[0025] The upper surface of a pair of T-shaped moving blocks 9 is connected with the same U-shaped loading block 10, the upper surface of U-shaped loading block 10 is also provided with vacuum generator 11, the upper surface of U-shaped loading block 10 is also provided with hydraulic telescopic rod 12, the extension rod of hydraulic telescopic rod 12 is also provided with penetrated rectangular mounting plate 13, the upper surface of rectangular mounting plate 13 is also provided with circular ring mounting sleeve 14, and a pair of circular ring mounting sleeves 14 are rotatably connected.

[0026] The lower surface of rectangular mounting plate 13 is also provided with U-shaped limiting rod, and the rod body of U-shaped limiting rod is also provided with penetrated connecting block, the lower surface of a pair of connecting blocks is fixedly connected with vacuum adsorption equipment 15, the lower surface of vacuum adsorption equipment 15 is also provided with suction disc, the upper surface of vacuum adsorption equipment 15 is also communicated with arc-shaped connecting pipe 16, arc-shaped connecting pipe 16 is communicated with control equipment on vacuum generator 11, the upper surface of T-shaped moving block 9 is also provided with inductor 17, the vertical surface of inductor 17 is communicated with signal transmission line 18, the end point of signal transmission line 18 away from inductor 17 is communicated with control equipment, and the control equipment belongs to: a kind of of microcontroller;

[0027] Controller is a small, high-density control chip. It can connect various sensors through its input pins, and collect signals generated by the sensors. For example, a simple vacuum adsorption control system based on microcontroller, the microcontroller can connect the pressure sensor through its analog input pin, and obtain the voltage value corresponding to the pressure signal.

[0028] The microcontroller runs a pre-written program inside to judge the collected signals. When the set conditions are met, the microcontroller sends a control signal. This control signal can directly drive a small vacuum generator, or through a drive circuit to start the vacuum generator, to realize the vacuum adsorption function;

[0029] The working principle of the vacuum adsorption device 15: vacuum adsorption is to use vacuum pumps and other equipment to generate a pressure environment lower than the outside atmospheric pressure in the adsorption device. According to the principle of fluid mechanics, when the outside atmospheric pressure is greater than the internal pressure of the adsorption device, a pressure difference pointing to the inside of the adsorption device will be generated. This pressure difference acts on the surface of the adsorbed object, thereby tightly adsorbing the object on the adsorption device;

[0030] In use, first let the staff put the coded articles on the placement plate 4, and then the coded articles can be coded. After coding is completed, first start the drive motor 7, because the output end of the drive motor 7 penetrates and connects the circular surface of the threaded conveying rod 6, and the inside of the rectangular moving groove 5 is also provided with a cylindrical guide rod 8, and the rod body of the threaded conveying rod 6 is also sleeved with a T-shaped moving block 9, and the inner ring of one of the T-shaped moving blocks 9 is also provided with a threaded groove, which is in meshing relationship with the threads of the threaded conveying rod 6;

[0031] Therefore, with the start of the drive motor 7, a pair of T-shaped moving blocks 9 will move, and after moving, the hydraulic telescopic rod 12 will be started. At this time, the extension rod of the hydraulic telescopic rod 12 will be lowered, because the extension rod of the hydraulic telescopic rod 12 is also provided with a penetrated rectangular mounting plate 13, and the lower surface of the rectangular mounting plate 13 is also provided with a U-shaped limiting rod, and the rod body of the U-shaped limiting rod is also provided with a penetrated connecting block.

[0033] When the pair of T-shaped moving blocks 9 move to the position directly above the inclined discharge port formed on the upper surface of the operation table main body 1, the driving motor 7 will stop, and then the hydraulic telescopic rod 12 will rise. When the vacuum suction device 15 is out of the range of the inductor 17, the inductor 17 will send a signal to stop the power supply of the vacuum generator 11. After the vacuum generator 11 stops, because the three-way electromagnetic valve is also arranged on the vacuum generator 11, the air can be filled into the suction cup in negative pressure, and the vacuum suction device 15 will not have suction force, so that the finished product falls into the collecting box through the discharge port.

[0034] Embodiment 2

[0036] Before the steps in Embodiment 1 are used, first pinch the longer rectangular moving plate 20 with the hand, and then adjust the U-shaped extension sleeve 21 according to the length of the article. Because the accommodation sleeve in the U-shaped extension sleeve 21 is in sliding relationship with the rectangular moving plate 20, after the U-shaped extension sleeve 21 is adjusted, the article is placed, and then the hand is released. Then the steps in Embodiment 1 can be operated.
