Technical Field
[0001] The utility model relates to the technical field of static elimination devices, in particular to a static elimination device for precision plastic parts. Background Technique
[0002] Static electricity refers to the static charges accumulated on the surface of certain materials. This phenomenon is usually caused by friction or contact separation between different materials (for example, when two different materials rub against each other, electrons transfer from one material to another).
[0003] In the prior art, when a plastic part rubs against other objects (such as clothes, paper, other plastics, etc.), electrons will transfer between the two materials. Due to the insulating property of plastics, these charges cannot dissipate quickly, so they will accumulate on the surface of the plastic part. If there is a large amount of static electricity on the plastic part, it may cause hazards such as explosion. Therefore, the utility model proposes a static elimination device for precision plastic parts to solve the above problems. Content of the Utility Model

[0019] Embodiment 1: Please refer to Figures 1-4 , the present utility model provides a technical solution: a static eliminator for precision plastic parts, including: a removal box 1, a driving rack 2 is arranged at the top of the removal box 1, a gear 3 is meshed with one side of the driving rack 2, a driven rack 4 is meshed with one side of the gear 3, static bars 5 are installed on the lower sides of the driving rack 2 and the driven rack 4, a chain 6 is arranged under the static bars 5, a fixing plate 7 is fixedly connected to one side of the chain 6, a support block 8 is fixedly connected to the fixing plate 7, a threaded rod 9 is rotatably sleeved in the support block 8, and a clamping block 10 is installed on the threaded rod 9.
[0020] The clamping block 10 is threadedly connected to the threaded rod 9. By rotating the threaded rod 9 under the limitation of the support block 8, the distance between the clamping blocks 10 can be adjusted, so that the clamping blocks 10 clamp the precision plastic parts. Under the operation of the chain 6, the chain 6 drives the fixing plate 7 to move into the removal box 1, thereby indirectly driving the precision plastic parts to move into the removal box 1. When the precision plastic parts just enter the removal box 1, the driving rack 2 reciprocates on the top of the removal box 1, thereby driving the gear 3 to rotate, so that the gear 3 meshes and drives with the driven rack 4, and further realizes the synchronous reciprocating movement of the driving rack 2 and the driven rack 4, so that the driving rack 2 and the driven rack 4 drive the static bars 5 to repeatedly contact the plastic products, achieving the effect of removing static electricity.
[0021] Embodiment 2: On the basis of Embodiment 1, remove the fixed frame 11 fixedly connected to the upper surface of the removal box 1. A small motor 12 is fixedly sleeved on the fixed frame 11. The output end of the small motor 12 is fixedly connected to one end of the driving block 13. The other end of the driving block 13 is fixedly sleeved with a sliding rod 14. The fixed frame 11 is fixedly installed on the top of the removal box 1. The small motor 12 is fixedly supported by the fixed frame 11. One end of the driving block 13 is fixedly connected to the output end of the small motor 12. The other end of the driving block 13 is fixedly sleeved with a sliding rod 14. One end of the sliding rod 14 is slidably sleeved in the connecting frame 15. One end of the connecting frame 15 is fixedly installed on the upper side of the driving rack 2. The lower surfaces of the driving rack 2 and the driven rack 4 are both fixedly connected to one end of the connecting rod 16. The other end of the connecting rod 16 is fixedly connected to the static electricity bar 5. The upper surface of the driving rack 2 is fixedly installed with a connecting frame 15. An arc-shaped hole is opened in the connecting frame 15. The sliding rod 14 is slidably sleeved in the arc-shaped hole opened in the connecting frame 15. The static electricity bar 5 is fixedly installed on the lower surfaces of the driving rack 2 and the driven rack 4 through the connection of the connecting rod 16. One side of the top of the removal box 1 is fixedly installed with a power supply box. The power supply box is electrically connected to the static electricity bar 5 through a stretchable connecting wire. The two sides of the connecting rod 16 are slidably connected to the limiting plates 17. The limiting plates 17 are fixedly connected to the removal box 1. Plasma fans 18 are fixedly installed on both sides of the top of the removal box 1. The gear 3 is rotatably sleeved on the limiting shaft 23. The bottom of the limiting shaft 23 is fixedly sleeved on the top of the removal box 1. The connecting rod 16 is limited by the limiting plates 17. The limiting plates 17 are fixedly installed on the removal box 1.
[0022] The small motor 12 is electrically connected to an external terminal control device. The rotation of the output end of the small motor 12 drives the rotation of one end of the driving block 13. The driving block 13 slides the sliding rod 14 fixedly sleeved on its other end in the connecting frame 15 to drive the connecting frame 15 to move. Thus, the connecting frame 15 drives the driving rack 2 fixedly connected to it to move. The driving rack 2 slides along the direction of the limiting plate 17 through the cooperation of the connecting rod 16 and the limiting plate 17. Thus, the driving rack 2 meshes with the gear 3, and the gear 3 meshes with the driven rack 4 for transmission. Thus, the driving rack 2 and the driven rack 4 slide reciprocally in the direction of the limiting plate 17 under the limitation of the limiting plate 17, and indirectly drive the static electricity bar 5 to move reciprocally. Thus, the contact area between the static electricity bar 5 and the plastic product is enlarged, and the purpose of removing static electricity can be better achieved. At the same time, the plasma fans 18 fixedly installed on both sides of the top of the removal box 1 are electrically connected to an external terminal control device. With the help of the plasma fans 18, air is blown onto the surface of the plastic parts to further improve the static electricity removal effect.
[0023] Embodiment 3: On the basis of Embodiment 2, a limiting rod 19 is arranged on the lower side of the plasma fan 18. Both ends of the limiting rod 19 are fixedly connected to the support blocks 8. The clamping block 10 is sleeved on the threaded rod 9 and is in threaded connection with the threaded rod 9. Both ends of the chain 6 are engaged with the sprockets 20. There are two fixing plates 7 which are symmetrically arranged with respect to the central plane of the removal box 1. The upper surface of the fixing plate 7 is fixedly connected to the support block 8. The lower surface of the fixing plate 7 is fixedly connected to the chain 6. The limiting rod 19 is fixedly connected between the two support blocks 8. There are two chains 6 which are symmetrically arranged. Two sections of threads with opposite helix directions are provided on the threaded rod 9. The sprocket 20 is fixedly sleeved on the fixed shaft 21. Both ends of the fixed shaft 21 are rotatably sleeved in the support seat 22. The clamping block 10 is slidably sleeved on the limiting rod 19. One set of sprockets 20 on one side is rotatably sleeved on the fixed shaft 21, and the fixed shaft 21 is fixedly sleeved in the support seat 22. One set of sprockets 20 on the other side is also rotatably sleeved on the fixed shaft 21. At the same time, the fixed shaft 21 on this side is fixedly connected to the connecting shaft. A worm gear is fixedly sleeved on the connecting shaft. The upper side of the worm gear is in meshing transmission with the worm. One end of the worm is rotatably sleeved on the fixed seat, and the other end of the worm is fixedly connected to the output end of the large motor. Through the meshing transmission of the worm gear and the worm, the connecting shaft drives the fixed shaft 21 to rotate, thereby realizing the meshing transmission of the chain 6 and the sprocket 20.
[0024] When it is necessary to remove static electricity from plastic parts products, by placing them between the clamping blocks 10 and twisting the threaded rod 9 under the limitation of the support block 8, the threaded rod 9 drives the clamping blocks 10 to move towards each other, so as to clamp and fix the plastic products through the two clamping blocks 10. Through the meshing transmission of the chain 6 and the sprocket 20, the chain 6 drives the fixing plate 7 to approach the removal box 1, thereby indirectly driving the plastic products to move into the removal box 1. After the static electricity removal is completed, the sprocket 20 rotates in the reverse direction, and the plastic products can be taken out. There are three groups of clamping blocks 10, so that multiple plastic products can be de-electrified at one time, improving the efficiency of de-electrification, and thus ensuring the stability of the plastic products when contacting the static electricity rod 5, and further improving the static electricity removal effect.
