This utility model includes a mounting base, with several transverse moving devices fixedly mounted on the front end face of the mounting base. A longitudinal moving device is movably connected to the front end face of the transverse moving device, and a placement structure is movably connected to the front end face of the longitudinal moving device. The transverse moving device includes several parallel transverse tracks, each transverse track being movably connected to a transverse moving seat.

[0025] Both ends of the support frame 3 are fixedly provided with connecting sleeves 19. A connecting screw 20 is provided through the inside of the connecting sleeve 19. The connecting screw 20 is fixedly provided at one end of the slide rail 4. Two connecting nuts are provided in the middle of the connecting screw 20 through threads.

[0027] Working principle of this utility model:

[0028] When this device is in use, the circuit board 22 of the integrated circuit to be processed is fed through the loading platform 21. The circuit board 22 slides under the fixed frame 2 along with the loading platform 21. During this process, the spring applies a pushing force to the positioning seat 17, causing the positioning seat 17 to drive the connecting arm 13 to rotate. The connecting arm 13 drives the transmission rod 14 to rotate. The transmission rod 14 drives the movable seat 7 to rotate through the sliding sleeve 15. The movable seat 7 drives the conductive plate 8 to rotate around the pin at the bottom of the connecting seat 6. At this time, the lower surface of the conductive plate 8 contacts the upper surface of the circuit board 22. The static electricity on the circuit board 22 is transferred to the conductive plate 8. During this process, the conductive plate 8 is connected to the ground wire through the terminal block 11. The static electricity is released through the terminal block 11 and the ground wire to avoid the static electricity from affecting the electronic components.

[0029] When processing circuit boards 22 of different specifications, the positioning bolt 18 can be rotated to separate it from the slide rail 4, thereby releasing the limit of the slide block 5. At this time, the position of the slide block 5 can be adjusted to adjust the position of the conductive plate 8, so as to ensure that the conductive plate 8 can contact the surface of the circuit board 22 without affecting the placement of electronic components. By adjusting the position of the nut on the connecting screw 20, the position between the connecting screw 20 and the connecting sleeve 19 can be adjusted, thereby adjusting the height of the conductive plate 8 to ensure that the conductive plate 8 can contact the surface of the circuit board 22.

[0030] It should be noted that in this embodiment, the loading platform 21 and the chip mounter head 23 both adopt existing structures in the prior art, and the method of transmitting static electricity through contact and releasing static electricity through the ground wire in this embodiment is common sense in physics.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
