The trackpad and plastic film are glued together, and the extra plastic sheeting around each glued trackpad is cut off by the robot. Pen Fun Pavilion www.biquge.info put a magnet block on the trackpad and glue it to the plastic film, and after a few days all the trackpads were processed.

Zhang Tao glued all the trackpads with magnets to a printed board with a robot, and each printed board was glued with 100 pieces, a total of 100 sheets. Zhang Tao made a box out of six one-meter-long square printed boards, the lid of the box was fixed with plastic hinges, and the plastic plates on both sides had grooves milled out by a milling cutter to place the printed boards.

Zhang Tao operated the robot to insert a hundred printed boards into the slot, a hundred layers of printed boards with adhesive touch boards are connected by wires and copper sheets, and there is a longitudinal copper sheet in the groove of the printed board on both sides of the box and a hundred layers of printed board copper contact, and a printed board is placed on the top layer, on which are placed batteries and switches, as well as signal transmitters and receivers.

I made a remote control with a signal transmitter and receiver, as well as a printed board, capacitors, resistors, wires, etc., and adjusted the frequency of the signal transmitter to a frequency with the signal receiver in the switch, and pressed the switch of the magnet sensor and remote control.

After closing the lid of the printed board, I weighed eighty pounds with a scale. Zhang Tao made a wooden shelf with wooden planks and long strips of wood, installed two directional wheels and two steering wheels under the wooden shelf, nailed four long wooden strips to the wooden shelf, and fixed four zigzag chains on the wooden strips, and the groove plate on which the magnet sensor was placed on the wooden shelf could move up and down on the serrated teeth of the chain.

After the wood car is finished, all kinds of steel plates and iron plates are taken out of the material warehouse, and the steel plates and iron plates of several different materials are processed into a little more than one millimeter with a machine tool, and the steel plates are put into a grinding machine and ground to one millimeter.

Take the steel plate to the bottom of the magnet sensor, turn on the switch with the remote control to sense the steel plate, the magnetic force emitted by the magnet sensor radiates to the steel plate, and produces a magnetic force on the steel plate, and the magnetic force makes the 5 mm magnet press the plastic film.

Each small magnet block corresponds to a slider resistor on a touchpad, and when the resistor is pushed by the magnet block, the resistance becomes smaller, and the current of the capacitor on the printed board increases, and it is transmitted to the digital simulator at the switch through the wire.

The digital simulator sends the electrical signal through the signal transmitter, and then receives the signal in the central processing unit and digital simulator of the remote control, converts the electrical signal into a digital signal, and then calculates the current of the magnet sensor through the CPU.

The 10,000 small magnets in the magnet sensor can be touched by the measured steel plate or the magnetic force reflected back from the iron plate, the magnetic force is an invisible force, and it will not be blocked by the small magnet block in front, but the magnetic force will be smaller and smaller the further back, and the amount of current obtained is about the same in each row, and the 10,000 current received in the remote control of Zhang Tao is copied to the computer, and the software is converted into a certain thickness of the steel plate according to the size of each row of current.

Since the steel plate is flat, the resulting current value is just as large as the current induced by the first row of small magnets. Zhang Tao divides the current amount obtained by each row of trackpads by 100 to obtain the average value of each row of trackpads, and the ratio of this 100 values is used as the current value of this type of steel plate with a thickness of one millimeter, which can be used as a standard to measure other steel materials with different thicknesses.

Just as one second is the time of the two basic forms of cesium atoms and the time between the transition radiation of 9,196,231,770 weeks at sea level and zero magnetic field, the current of a millimeter of steel plate measured by Zhang Tao is not measured casually, even if the resistance of a larger slider is replaced, the ratio between them is the same.

After doing various steel and iron plate tests, Zhang Tao stored the values in the computer, and then used the printer to print out two copies of paper as a backup of the data. The next day, Zhang Tao had a good night's sleep, practiced in the morning, had breakfast, and sent the girls outside the farm to the workshop.

Zhang Tao has an income this year, and several women have cars, and cars in Iceland are very cheap, two or three times cheaper than in China. Zhang Tao asked Lily and Leah to sell their original cars, and they both bought a better jeep, and they were not tired of driving a good car, and now they are not short of money, and they will come back after selling the gold in a few days. In total, it cost 60 million Icelandic krona, which is equivalent to 3 million yuan.

Put on your overalls and protective gear and place the magnet sensor on top of the wooden shelf, then push the wooden shelf next to the submarine. Turn the magnet sensor over and turn it on with the remote control after using it to turn on the switch.

The welding point is scanned by moving the wood plate up and down on the chain teeth, and the computer of the remote control converts the final current ratio obtained by multiplying the received current value by the reference ratio into an image, and a picture of the simulated welding place appears on the screen.

The welding material is also the same type of steel plate, but the steel plate is quickly melted by the assembly welding machine, and the image obtained is very clear, Zhang Tao moved the wooden frame to scan the shell of the submarine, and saw that there was no leakage anywhere.

The welds are very thick, and the extra parts have to be grinded down, otherwise it will increase the resistance in the water. The robot clamp was replaced with a grinding wheel, and the program was set, and the excess steel plate at the weld of the submarine was grinded.

There is a lake that is not too big in the training ground, Zhang Tao went to the market to buy a crane, and after a meeting on the farm, he put the submarine in the car and transported it to the lake to see the balance of the submarine, and then installed some stones in the submarine to let it sink, and the balance under the water is also very good.

The length of the submarine is 60 meters, the width is 30 meters, it belongs to small and medium-sized submarines, and it can be lowered under the crane for easy transportation.

When the girls came back, they saw Zhang Tao putting stones in the submarine on the edge of the lake, and they all came over and asked Zhang Tao curiously what he was doing, and Zhang Tao said that he wanted to build a submarine and take a few women to the bottom of the sea to play, which caused the girls to cheer and give Zhang Tao a kiss, and after the women walked away, they wiped off the four lipstick lipstick lip prints on their faces and continued to work.

The submarine was very well balanced under water and on the surface, and the submarine was hoisted out of the lake with a crane and a cable and transported back to the workshop. Next, the welding of the machine at the bottom of the submarine began, with a hydroballast chamber and an air chamber, as well as an entry and exit chamber.

After all the welding is completed, there is no problem after the magnet sensor is tested, and the industrial robot is controlled to replace the grinding wheel fixture to smooth the excess steel plate at the weld. Then the shell of the submarine is plated with a layer of chromium to improve the wear resistance and corrosion resistance of the submarine shell, and after the submarine shell is cooled, the industrial robot is sprayed with a layer of oxide rubber waterproof paint.

This kind of lacquer is made of natural rubber, which will not pollute the seawater, and the inner shell of the submarine is also painted after leaving the propeller and the place that needs to be cut in and out of the cabin.

After spitting out the paint and waiting for two days to dry, Zhang Tao cut the steel plate reserved for the entrance and exit compartments at the bottom of the submarine, and installed the propeller and propulsion system.

The power in the submarine Zhang Tao is designed for three power forms, the conventional is diesel power generation, if the diesel engine fails, there will be liquid hydrogen and liquid oxygen as the second backup power, the third power Zhang Tao has made a reservation in the middle of the submarine, and the first two types of power can be used as backup power after having the ability to collect the star core.

The star core is the most common power at the end of the 21st century, what oil, alcohol are all eliminated, a few grams of weight star core can make a car scrap and energy, is super environmentally friendly new energy.
