Compared to desktop computers, laptop computers are similar in function, but their lightweight design and battery-powered nature allow users to operate the computer anytime, anywhere.

[0003] In the current technology of laptop manufacturing, the outer shell needs to be polished. Usually, the shell is fixed by a clamping structure, and then the polishing equipment is manually attached to the shell surface for polishing. However, manual operation is cumbersome, requiring multiple adjustments and controls by the operator, which increases the complexity of production. Moreover, due to the reliance on manual operation, errors can easily occur due to differences in the operator's skill level or improper operation, resulting in uneven polishing effect and even damage to the shell surface, affecting product quality.

[0004] To address these issues, we have developed an automated grinding fixture structure for laptop casings. Utility Model Content

When placing the outer shell, the outer shell can be roughly positioned through the junction of the two positioning frames 4. One end of the connecting rod 8 is rotatably connected to the bottom of the slider 6 through a rotating shaft. The input end of the fan 9 extends to the outside of the positioning platform 3 to draw in air. Multiple jet heads 11 are provided on one side of the inner cavity of the positioning platform 3 to blow the waste. Example

[0028] Please see Figure 1-5 Based on Embodiment 1, the positioning assembly further includes a cylinder 12, which is fixedly connected to the top of the base plate 1. A right-angle plate 13 is fixedly connected to the free end surface of the cylinder 12. A lifting plate 14 is fixedly connected to the top of the right-angle plate 13. A disc 15 is fixedly connected to the bottom of the lifting plate 14. A grinding head 16 is provided at the bottom of the disc 15. A linkage plate 17 is fixedly connected to the free end of the cylinder 12. One side of the linkage plate 17 is movably connected to one end of the connecting rod 8 via a rotating shaft. A collection frame 18 is provided on one side of the inner cavity of the positioning platform 3. A cover is movably connected to one side of the positioning platform 3 via a hinge, and a handle is fixedly connected to one side of the cover. The positioning platform 3 has a placement groove in its inner cavity, and a chip discharge port 19 is provided on one side of the placement groove. The bottom of the positioning frame 4 is fixedly connected to the inner cavity of the placement groove. A sliding groove is provided at the bottom of the positioning frame 4, and the inner cavity of the sliding groove extends to the outside of the positioning platform 3. The surface of the connecting rod 8 is movably connected to the inner cavity of the sliding groove. Limiting strips 20 are fixedly connected to both sides of the support plate 2. Limiting grooves are provided on both sides of the lifting plate 14, and one side of the limiting strip 20 is slidably connected to the inner cavity of the limiting groove.

[0029] Specifically: the right-angle plate 13 on the free end surface of cylinder 12 is located at the bottom of linkage plate 17 so as to move with the free end of cylinder 12; the disc 15 and grinding head 16 at the bottom of lifting plate 14 can drive grinding head 16 to perform comprehensive and uniform grinding on the surface of the outer shell through a self-drive system; linkage plate 17 is movably connected to connecting rods 8 through rotating shafts around its perimeter so as to drive four sliders 6 to move simultaneously; the placement slot is set at the center of the inner cavity of positioning table 3 for placing the outer shell to be ground, and positioning frame 4 is set inside; the jet head 11 is set on one side of the inner cavity of the placement slot; the linkage plate 17 can be connected to the slider 6 through the sliding groove; the limiting strip 20 supports and limits the lifting plate 14.

[0030] The working principle of this utility model is as follows: When it is necessary to automatically polish the laptop shell, the required shell is first placed in the placement slot of the positioning table 3. Then, the cylinder 12 is started by the external controller. The cylinder 12 drives the linkage plate 17 to move downward. The linkage plate 17 drives the connecting rod 8 to move. The connecting rod 8 drives the slider 6 to move, so that the clamping block 7 at the top of the slider 6 can move towards the center of the placement slot cavity to clamp and position the laptop shell around its perimeter.

[0031] When the cylinder 12 is working, it will also drive the right angle plate 13 to move. The right angle plate 13 drives the lifting plate 14 to slide on the surface of the slide bar. The lifting plate 14 drives the grinding head 16 at the bottom of the disc 15 to move, so that when the clamping block 7 clamps and positions the outer shell, the grinding head 16 can fit with the surface of the outer shell, thereby ensuring the consistency of grinding depth and effect.

[0032] After positioning, the grinding head 16 can be started to grind the outer shell through the external control system. During grinding, the blower 9 can be started through the external controller. The blower 9 can blow compressed air into the jet head 11 through the air supply pipe 10. The jet head 11 then sprays out the compressed air. The airflow can effectively blow the debris generated during the grinding process to the chip discharge port 19, and guide the debris into the collection frame 18 for centralized collection through the chip discharge port 19. After the debris is collected, the user can open the cover of the collection frame 18 to centrally process and clean the accumulated debris.
