Description

Technical Field

[0001] This utility model relates to the field of laptop shell painting technology, and more specifically to an electrostatic shielding automatic positioning auxiliary device. Background Technology

[0002] The laptop casing is the basic protective barrier for the laptop. During the production process, the laptop casing can be painted to enhance its appearance. Before painting, areas that do not need to be painted need to be masked to prevent static electricity.

[0003] A search revealed a novel electrostatic powder coating masking device (publication number CN213886734U), comprising a chassis, a powder supply cylinder, and a masking device. The masking device, housed inside the chassis, includes a tray and a masking plate. The tray has a groove on its surface, and the masking plate has a graphene layer on its surface. Pull rods are attached to both ends of the masking plate, with a pull ring fixedly connected to one end of each rod, and four anti-slip studs fixedly connected to the other end of the rod away from the pull ring. A ball bearing is fixedly and rollingly connected to one end of the masking plate. This invention, by using the masking device, allows for easy placement of items. After placing an item, the masking plate is slid to the desired masking position, and the pull ring is lowered, causing the anti-slip studs to engage with the groove. The graphene layer on the masking plate effectively isolates static electricity. Currently, most powder coating machines are inefficient for single-sided spraying, requiring pre-coating and subsequent manual removal of the film. Furthermore, the applied film cannot be reused, increasing costs. This device effectively avoids these problems and improves ease of use.

[0004] Existing laptop casings require manual application of anti-static film during spraying, which is time-consuming, labor-intensive, and inefficient. In addition, spray powder can easily seep into the mounting holes of the casing, thus affecting the spraying effect. Based on this, this utility model designs an automatic positioning auxiliary device for electrostatic shielding to solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electrostatic shielding automatic positioning auxiliary device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an automatic positioning auxiliary device for electrostatic shielding, comprising a base, a set of support frames fixedly connected to the top of the base, a motor mounted on the top of the support frames, a main threaded rod fixedly connected to the output end of the motor, a transmission mechanism provided on the outer wall of the main threaded rod, and the main threaded rod synchronously driving a secondary threaded rod to rotate through the transmission mechanism, both the main threaded rod and the secondary threaded rod passing through a sliding plate and threadedly connected thereto, the sliding plate slidably connected to the inner wall of the support frame, fixing plates fixedly connected to both sides of the outer wall of the sliding plate, a support rod fixedly connected to the bottom end of each fixing plate, and an anti-static plug passing through the support rod. Each of the following components is fixedly connected to a limiting rod at its bottom end. The limiting rod passes through a limiting post, which is fixedly connected to the top of the base. A set of outer shells is fitted to the top of the base. Several circular grooves are formed on the top of the outer shells. Each circular groove has a mounting hole at its bottom end. The limiting post passes through the mounting hole and fits into it. The bottom end of the antistatic plug is located in the circular groove and fits into it. A groove is formed on the top of the antistatic plug corresponding to the support rod. The bottom end of the support rod is located in the groove and fits into it. A sliding groove passes through the outer wall of the support rod. A set of sliders is slidably connected in the sliding groove. Springs are fixedly connected between the sliders. The sliders pass through both sides of the outer wall of the antistatic plug.

[0007] Furthermore, vertical grooves are provided on both sides of the inner wall of the support frame corresponding to the sliding plate, and both ends of the sliding plate are located in the vertical grooves and slidably connected thereto.

[0008] Furthermore, a support plate is fixedly connected to the inner wall of the support frame, and the bottom ends of the main threaded rod and the auxiliary threaded rod are rotatably connected to the support plate, while the top end of the auxiliary threaded rod is rotatably connected to the support frame.

[0009] Furthermore, the transmission mechanism includes transmission wheels fixedly connected to the outer walls of the main threaded rod and the auxiliary threaded rod, and a synchronous belt is sleeved between the transmission wheels.

[0010] Furthermore, a limiting groove is formed at the top of the limiting post corresponding to the limiting rod, and the limiting rod is located in the limiting groove and fits against it.

[0011] Furthermore, the antistatic plug has through grooves on both sides of the outer wall corresponding to the slider, and the slider passes through the through grooves and fits into them.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model achieves rapid positioning of the outer shell by aligning the mounting hole of the outer shell with the limiting post at the top of the base and placing it downwards on the base. The limiting post passes through the mounting hole and the bottom end of the outer shell is completely in contact with the base. The motor drives the main thread rod to rotate, and the main thread rod drives the auxiliary thread rod to rotate through the synchronous belt. This, in turn, drives the slide plate, antistatic plug and limiting rod to move downwards along the vertical groove. After the limiting rod passes through the mounting hole, it is inserted into the limiting groove. At the same time, the bottom end of the antistatic plug is inserted into the circular groove. This not only provides antistatic protection for the mounting holes of multiple sets of outer shells, but also prevents the spray powder from seeping into the mounting holes and affecting the spraying effect of the outer shell.

[0014] 2. In this utility model, when the sliders on both sides of the antistatic plug are pressed, the sliders move closer to each other along the slide groove and compress the spring. When the sliders are fully inserted into the slide groove, the antistatic plug can be removed downwards for replacement, reducing the cost of later maintenance and replacement. Similarly, during installation, after pressing the sliders and aligning the groove with the support rod, the antistatic plug is inserted upwards. When the sliders coincide with the through groove, the sliders move away from each other along the slide groove under the action of the spring and are inserted out of the through groove, realizing the quick installation and fixation of the antistatic plug.

A synchronous belt 132 is sleeved between the transmission wheels 131. A support plate 12 is fixedly connected to the inner wall of the support frame 6. The bottom ends of the main threaded rod 10 and the auxiliary threaded rod 11 are rotatably connected to the support plate 12, and the top end of the auxiliary threaded rod 11 is rotatably connected to the support frame 6. Each of the 11 plates has a sliding plate 8 threaded through it and connected to it. The sliding plate 8 is slidably connected to the inner wall of the support frame 6. Vertical grooves 7 are opened on both sides of the inner wall of the support frame 6 corresponding to the sliding plate 8.

Limiting rods 17 are fixedly connected to the bottom of the antistatic plugs 3. Limiting rods 17 pass through limiting posts 14. Limiting grooves 23 are opened on the top of the limiting posts 14 corresponding to the limiting rods 17. The limiting rods 17 are located in the limiting grooves 23 and fit with them. Limiting posts 14 are fixedly connected to the top of the base 1. A set of outer shells 2 are attached to the top of the base 1. Several circular grooves 16 are opened on the top of the outer shells 2. The bottom of the circular grooves 16 are all passed through There are mounting holes 15, and the limiting posts 14 all pass through the mounting holes 15 and fit against them. The mounting holes 15 of the outer shell 2 are aligned with the limiting posts 14 at the top of the base 1 and placed downwards on the base 1. The limiting posts 14 pass through the mounting holes 15 and the bottom of the outer shell 2 is completely fitted against the base 1, realizing the rapid positioning of the outer shell 2. The bottom of the antistatic plug 3 is located in the circular groove 16 and fits against it. The motor 9 drives the main thread rod 10 to rotate, and the main thread rod 10 drives the auxiliary thread rod 11 to rotate through the synchronous belt 132. In turn, it drives the slide plate 8, the fixing plate 5, the support rod 4, the antistatic plug 3 and the limiting rod 17 to move downwards along the vertical groove 7. After the limiting rod 17 passes through the mounting holes 15, it is inserted into the limiting groove 23. At the same time, the bottom of the antistatic plug 3 is inserted into the circular groove 16. While providing antistatic protection, it also prevents spray powder from seeping into the mounting hole 15 and affecting the spraying effect of the outer shell 2. The top of the antistatic plug 3 has a groove 22 corresponding to the support rod 4, and the bottom end of the support rod 4 is located in the groove 22 and fits against it.

When the sliders 19 on both sides of the antistatic plug 3 are pressed, the sliders 19 move closer to each other along the sliding groove 20 and squeeze the springs 21. When the sliders 19 are completely inserted into the sliding groove 20, the antistatic plug 3 can be removed downwards for replacement.This reduces the cost of later maintenance and replacement.

[0023] The working principle of this utility model is as follows: When painting is required, the mounting hole 15 of the outer shell 2 is aligned with the limiting post 14 at the top of the base 1 and placed downwards on the base 1. The limiting post 14 passes through the mounting hole 15 and the bottom end of the outer shell 2 is completely in contact with the base 1, achieving rapid positioning of the outer shell 2. The motor 9 drives the main thread rod 10 to rotate, and the main thread rod 10 drives the auxiliary thread rod 11 to rotate through the synchronous belt 132. This, in turn, drives the slide plate 8, the fixing plate 5, the support rod 4, the antistatic plug 3, and the limiting rod 17 to move downwards along the vertical groove 7. After passing through the mounting hole 15, the limiting rod 17 is inserted into the limiting groove 23. At the same time, the bottom end of the antistatic plug 3 is inserted into the circular groove 16. This provides antistatic protection for multiple sets of mounting holes 15 of the outer shell 2 while preventing the spray powder from seeping into the mounting hole 15. The mounting hole 15 affects the spraying effect of the outer shell 2. When the motor 9 rotates in the reverse direction, the slide plate 8 and the antistatic plug 3 move upward to facilitate the disassembly of the sprayed outer shell 2 and the replacement of the antistatic plug 3. When the sliders 19 on both sides of the antistatic plug 3 are pressed, the sliders 19 move closer to each other along the slide groove 20 and squeeze the spring 21. When the sliders 19 are fully inserted into the slide groove 20, the antistatic plug 3 can be removed downward for replacement, reducing the maintenance and replacement cost in the later stage. Similarly, when installing, after pressing the sliders 19, the groove 22 is aligned with the support rod 4, and the antistatic plug 3 is inserted upward. When the sliders 19 coincide with the through groove 18, the sliders 19 move away from each other along the slide groove 20 under the action of the spring 21 and are inserted out of the through groove 18, realizing the quick installation of the antistatic plug 3.
