Description

Technical Field

[0001] This utility model relates to the field of tablet computer technology, and in particular to a limiting device for polishing the back cover of a tablet computer. Background Technology

[0002] Tablet computers, also known as portable computers, are small, portable personal computers that primarily use touchscreens as their basic input device. The main purpose of polishing the back cover of a tablet computer is to improve the surface quality of the product, and the limiting device plays a crucial role in the polishing process.

[0003] Patent application number 202220728838.2 discloses a fixture for polishing the back cover of a tablet computer, including a base, on which a tooling base plate is fixedly mounted. The upper end of the tooling base plate has a protruding edge with rounded corners, and the lower end of the base plate has a groove. A lifting component is mounted on the base plate. Four sets of external clamping components are mounted circumferentially on the base opposite the tooling base plate, and an internal clamping component is mounted on the tooling base plate. The external clamping components and the internal clamping components are arranged opposite each other.

[0004] However, when using traditional limiting devices for polishing the back cover of a tablet, the fixing method is relatively simple, and it is not possible to polish the edge of the back cover, resulting in poor polishing effect. For example, the traditional method of fixing the back cover of a tablet is often a wrap-around limiting fixation. During the polishing process, the bottom and edge of the back cover need to be polished. The wrap-around method is not easy to polish the edge of the back cover, resulting in insufficient polishing. Utility Model Content

[0005] This utility model discloses a limiting device for grinding the back cover of a tablet computer, which aims to solve the technical problem that traditional limiting devices for grinding the back cover of tablet computers have a simple fixing method, cannot grind the edge of the back cover, and have poor grinding effect.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A limiting device for polishing the back cover of a tablet computer includes a worktable, a back cover body, and a limiting plate disposed on the worktable. The top outer wall of the worktable has an installation groove, and the bottom inner wall of the installation groove is provided with two electric telescopic rods. One end of the piston rod of the two electric telescopic rods is connected to the same grid frame. The back cover body is located on the grid frame. The top outer wall of the worktable is provided with four cylinders. The four outer walls of the limiting plate are provided with through holes. One end of the piston rod of each cylinder passes through the through hole and is connected to a limiting block. The four limiting blocks are used in conjunction with the back cover body.

[0008] In this solution, the electric telescopic rod working support grid frame is located in the matching position. The back shell of the tablet computer is placed on the grid frame, so that the back shell is higher than the limiting plate. Then the cylinder works, driving the four limiting blocks to fix and tighten around the back shell, so that the limiting blocks are located in the center of the back shell. The electric telescopic rod works in conjunction with the cylinder to adapt and fix back shells of different sizes and thicknesses. The position of the back shell above the limiting plate allows the grinding process to grind both the bottom and the edges, making the grinding more thorough.

[0009] In a preferred embodiment, a rubber pad is provided on the top outer wall of the grille frame, the rubber pad being located between the rear shell body and the grille frame, and grille holes are provided at equal intervals on the top outer walls of both the grille frame and the rubber pad.

[0010] Using the above technical solution, a layer of rubber pad is laid on the grid frame. Both the grid frame and the rubber pad have grid holes. The two work together to increase friction, making the rear shell body stable when placed on the grid frame. The rubber pad is in contact with the rear shell body, which can protect the rear shell body during placement and will not damage the rear shell body. The placement protection effect is better and the stable support effect is good.

[0011] As described above, a limiting device for grinding the back cover of a tablet computer includes a worktable, a back cover body, and a limiting plate disposed on the worktable. The top outer wall of the worktable has a mounting groove, and the bottom inner wall of the mounting groove has two electric telescopic rods. One end of the piston rod of each of the two electric telescopic rods is connected to the same grid frame. The back cover body is located on the grid frame. The top outer wall of the worktable has four cylinders. Through holes are formed on all four outer walls of the limiting plate. One end of the piston rod of each cylinder passes through the through hole and connects to a limiting block. The four limiting blocks cooperate with the back cover body. The limiting device for grinding the back cover of a tablet computer provided by this utility model has the technical effect of adapting to and fixing back cover bodies of different sizes and thicknesses, providing stable fixing, and simultaneously grinding the bottom and edges of the back cover body, resulting in thorough grinding and a better grinding effect.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0018] The limiting device for grinding the back cover of a tablet computer disclosed in this utility model is mainly used in scenarios where the traditional limiting device for grinding the back cover of a tablet computer has a relatively simple fixing method, cannot grind the edge of the back cover, and has a poor grinding effect.

[0019] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A limiting device for polishing the back cover of a tablet computer includes a worktable 1, a back cover body 4, and a limiting plate 3 disposed on the worktable 1. The top outer wall of the worktable 1 has an installation groove 2, and the bottom inner wall of the installation groove 2 is provided with two electric telescopic rods 6. One end of the piston rod of the two electric telescopic rods 6 is fixedly connected to the same grid frame 7. The back cover body 4 is located on the grid frame 7. The top outer wall of the worktable 1 is provided with four cylinders 5. The four outer walls of the limiting plate 3 are provided with through holes 11. One end of the piston rod of the cylinder 5 passes through the through hole 11 and is fixedly connected to a limiting block 10. The four limiting blocks 10 are used in conjunction with the back cover body 4.

[0020] In the specific working process, the electric telescopic rod 6 supports the grid frame 7 in the appropriate position, and the back shell body 4 of the tablet computer is placed on the grid frame 7 so that the back shell body 4 is higher than the limiting plate 3. Then the cylinder 5 works to drive the four limiting blocks 10 to move and fix and abut around the back shell body 4, so that the limiting blocks 10 are located in the center of the back shell body 4. Then the bottom and edge of the back shell body 4 are polished.

[0021] The height of the limiting block 10 is the same as the height of the limiting plate 3. The four limiting blocks 10 are located at the center of the outer wall of the rear shell body 4. In this way, when the limiting blocks 10 fix the rear shell body 4, they can fix the center of the rear shell body 4, thereby adapting to rear shell bodies 4 of different sizes and thicknesses. At the same time, they are fixed around the rear shell body 4, with a fixing effect in all directions, making the fixation more stable.

[0022] The inner walls of the four corners of the limiting plate 3 are all rounded. When the back shell body 4 is placed, it will overlap with the inner wall of the limiting plate 3. The rounded corner structure prevents the back shell body 4 from being scratched during placement and protects the back shell body 4.

[0023] The size of the grille frame 7 is smaller than that of the rear shell body 4, which allows for better placement of the rear shell body 4 and provides better support. Furthermore, the grille frame 7 is not obstructed by the limiting block 10 during its ascent and descent, ensuring smooth lifting and a better support contact position.

[0024] Reference Figure 2 and Figure 3 In a preferred embodiment, a rubber pad 8 is provided on the top outer wall of the grille frame 7. The rubber pad 8 is located between the rear shell body 4 and the grille frame 7. Grille holes 9 are evenly distributed on the top outer walls of both the grille frame 7 and the rubber pad 8.

[0025] Specifically, a rubber pad 8 is laid on the grid frame 7. Both the grid frame 7 and the rubber pad 8 have grid holes 9. The two work together to increase friction, so that the rear shell body 4 is placed stably on the grid frame 7. The rubber pad 8 is in contact with the rear shell body 4, which can protect the rear shell body 4 during placement and will not damage the rear shell body 4.

[0026] The grille frame 7 and the rubber pad 8 are both used in conjunction with the rear shell body 4. Thus, the grille frame 7 and the rubber pad 8 are used to support the rear shell body 4, making the rear shell body 4 stable. The material of the rubber pad 8 can also protect the rear shell body 4 from damage. The fit is tight and the support is stable.

[0027] Reference Figure 1 and Figure 4 In a preferred embodiment, four drainage holes 12 are provided on the bottom inner wall of the mounting groove 2, and the positions of the drainage holes 12 correspond to the positions of the gaps between the rear shell body 4 and the limiting plate 3.

[0028] Specifically, during the polishing process, the waste material generated during the polishing of the rear shell body 4 is discharged through the drain hole 12. After the polishing work is completed, the staff can clean the remaining waste material inside the workbench 1 by cleaning the workbench 1 side, which is discharged through the drain hole 12. The discharged waste material is then cleaned in a unified manner. The coordinated effect is good, making the whole device clean and tidy, and convenient for the next use.

[0029] Working principle: During use, the back cover 4 of the tablet computer is placed on the grille frame 7. The grille holes 9 on the grille frame 7, together with the rubber pad 8 and the grille holes 9 on the rubber pad 8, make the back cover 4 stable on the grille frame 7 without damaging the back cover 4. Then, the electric telescopic rod 6 works to support the grille frame 7 in the appropriate position, raising the back cover 4 slightly above the limiting plate 3. Then, the cylinder 5 works to drive the four limiting blocks 10 to fix and tighten around the back cover 4, so that the limiting blocks 10 are located in the center of the back cover 4. The bottom and edges of the back cover 4 are polished simultaneously and thoroughly. The waste generated during the polishing process is discharged through the drain hole 12. After the polishing work is completed, the staff can clean the remaining waste inside the cleaning workbench 1, and the waste will be discharged through the drain hole 12 again. Finally, the discharged waste is cleaned up uniformly.

[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
