The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0064] The working principle of the above embodiment is:

[0065] (1) The electronic board 10 is placed on the transmission belt 9 between the connecting plates 8. Through the setting of the sensor 7, when the electronic board 10 is located above the sensor 7 and the displacement cylinder 5, the transmission belt 9 stops and the displacement cylinder 5 starts to lift the electronic board 10 upward. Then the driving cylinder 2 is started. Through the pushing action of the cylinder, the sliding plate 302 is displaced and slid, thereby driving the rotating plate 305 to rotate through the hinge action, thereby adjusting the multiple adjustment rods 304, so that the multiple sliding plates 302 are displaced at the same time, and then the displacement plate 307 and the action plate 310 on the top of the sliding plate 302 are displaced, so as to position and load the supported electronic board 10. The overall work is convenient, the degree of automation is high, the loading effect is good, and it is beneficial to improve the efficiency of spot welding.

[0066] (2) Start the servo motor 17, and drive the driven gear 19 to rotate through meshing action. The displacement rod 21 is displaced through the threaded connection between the displacement rod 21 and the rotating rod 20, so that the overall pressure plate 23 is lowered. The electronic board 10 is protected by the airbag 24 on the side of the pressure plate 23. At the same time, the electronic board 10 is pressed down and stabilized by the pressure plate 23, so that the stability of the spot welding of the electronic board 10 is achieved. By adjusting the action of the motor 12052, the short rod 12053 is driven to rotate, so that the push rod 12054 pushes the tooth block 12055 toward the front, and the displacement of the drive plate 1204 is achieved through the meshing action with the rack 12051, so that the spot welding mechanism 13 on the drive plate 1204 is driven to move forward and backward. 1303 rotates, and drives the fixed tooth plate 1305 to move under the meshing action, thereby driving the movable motor 1309 and the sliding seat 1311 and the lower structure to move, thereby realizing the left and right displacement of the spot welding head and the tinning head. The movable motor 1309 rotates, and drives the movable tooth plate 1310 to move under the meshing action, and drives the sliding seat 1311 to move up and down, thereby realizing the up and down adjustment of the spot welding head and the tinning head, and realizing the multi-directional adjustment of the spot welding head and the tinning head as a whole, which is beneficial to improve the flexibility of the spot welding of the device, and the electronic board 10 is pressed by the pressing plate 23. Through the multi-directional adjustment of the spot welding head and the tinning head, the electronic board 10 can be set at multiple points, which is beneficial to further improve the work efficiency while improving the flexibility of the overall spot welding device.
