Specific implementation

[0030] The utility model will be further described below in conjunction with the embodiment shown in the drawings.

[0031] As Figures 1-3 Shown, it is the structural schematic view of the notebook computer shell with the anti-overpolishing jig of the utility model, it is usually used for assisting operator, polishes the burr of notebook computer shell surface, improves the production yield of notebook computer shell. The jig mainly includes base plate 1, limiting assembly and polishing assembly.

[0032] Base plate 1 is rectangular plate, is fixed on the machine table by screw fastening mode, limiting assembly is fixed at the top of base plate 1, the notebook computer shell to be polished is placed in limiting assembly, limiting assembly is limited to notebook computer shell, and subsequent polishing work of polishing assembly is facilitated.

[0033] Limiting assembly is formed by the multiple fixed plates sequentially arranged at the head and tail, the number of fixed plate is at least three, and the at least three fixed plates are sequentially arranged at the head and tail, to form the limiting groove for accommodating notebook computer shell in its interior.

[0034] As Figure 1 , 2 As shown, only the shape of one kind of limiting groove (i.e. rectangular limiting groove, matching rectangular shape notebook computer shell) is shown. In actual application, it can also be surrounded in the shape of triangle, square, pentagon and the like, and the number of fixed plate can be appropriately increased or decreased according to the different product shapes. When limiting notebook computer shell, fixed plate only needs to abut against the side of the shell.

[0035] As Figure 1 , 2As shown, in this embodiment, the fixing plate is divided into two first fixing plates 11 and two second fixing plates 14. The two first fixing plates 11 are close to the two long sides of the substrate 1, and the two second fixing plates 14 are close to the two short sides of the substrate 1. Therefore, the first fixing plates 11 and the second fixing plates 14 form a rectangular limiting groove inside them to match the rectangular product shell.

[0036] The oblique fixing plate 17 is provided at the connection between the first fixing plate 11 and the second fixing plate 14 and is used to limit the corners of the product to improve the polishing accuracy of the notebook shell.

[0037] The first fixing plate 11 and the second fixing plate 14 have the same shape, and the only difference is the length. Figure 7 As shown, the first through slots 12 are arranged at intervals on the first fixing plate 11 and pass through the first fixing plate 11. The first through slots 12 are in the shape of a rounded rectangle, which facilitates adjustment of the first fixing plate 11 to change the size of the internal limiting slot, thereby adapting to products of different sizes and improving versatility.

[0038] A first relief groove 13 is formed at the top of the first through-slot 12. Once the fastening bolt passes through the first through-slot 12 and is secured within the first fixing groove 8 of the base plate 1, the first relief groove 13 accommodates the bolt head. This prevents the polishing assembly from colliding with the bolt head when it slides along the upper surface of the fixing plate to polish the laptop case.

[0039] The first through slot 12 is provided to change the distance between the two first fixing plates 11. The second fixing plate 14 has the same shape as the first fixing plate 11, and the second through slot 15 is provided to change the distance between the two first fixing plates 11.

[0040] The distance between the second fixing plates 14 can be used to adjust the size of the internal limiting groove to adapt to products of different sizes and improve versatility.

[0041] like Figure 8 As shown, the oblique fixing plate 17 is "L"-shaped, and the oblique through slot 18 passes through the oblique fixing plate 17. When the first fixing plate 11 and the second fixing plate 14 are adjusted outward, the oblique fixing plate 17 is adjusted outward along the oblique angle.

[0042] like Figure 5 、 6 As shown, the main air channel 4 and the secondary air channel 5 are opened in the substrate 1 and the main air channel 4 is externally connected to a vacuum pump. The adsorption holes 3 are spaced apart on the top of the substrate 1 and are connected to the secondary air channel 5. When the notebook shell is placed in the limiting groove, the vacuum pump draws air to vacuum the main air channel 4 and the secondary air channel 5, thereby firmly adsorbing the notebook shell in the limiting groove of the substrate 1, facilitating the polishing work of the polishing component.

[0043] like Figure 3As shown, a buffer plug 6 is positioned within the suction hole 3, and a plug hole 7 extends through the buffer plug 6 and communicates with the secondary airway 5. The height of the buffer plug 6 is greater than the depth of the suction hole 3 and the buffer plug 6 is made of rubber. The operator holds the polishing assembly and slides it along the upper surface of the fixed plate to polish the notebook product within the retaining groove. During the polishing process, the notebook product comes into close contact with the underlying base plate 1, squeezing the buffer plug 6 to provide cushioning and shock absorption for the notebook shell, protecting the notebook product's surface.

[0044] The chip removal hole 2 passes through the base plate 1 and is close to the inner side of the fixed plate. The bottom of the chip removal hole 2 is connected to an external vacuum pump. During the polishing process, burrs, powder, etc. polished off the surface of the notebook shell will fall into the limiting groove of the base plate 1. The dust and the like will be promptly removed through the chip removal hole 2 to avoid affecting the placement of subsequent notebook products.

[0045] like Figure 4 The figure shows a schematic diagram of the structure of the polishing assembly, which includes a polishing plate 20, a grip 21, and a transition portion 22. The grip 21 is integrally connected to the top of the polishing plate 20. The operator holds the grip 21 and then presses the polishing plate 20 against the fixed plate. The height of the notebook shell is equal to the thickness of the fixed plate. The polishing plate 20 slides along the upper surface of the fixed plate to polish off the burrs and protrusions on the surface of the notebook shell (because the polishing plate 20 presses against the upper surface of the fixed plate, it will only contact the burrs and protrusions on the surface of the notebook shell during polishing, and will not cause damage to the original structure of the notebook shell).

[0046] The transition portion 22 is arc-shaped and is disposed between the handle 21 and the grinding plate 20 to match the palm of the operator.

[0047] The method of using the anti-over-wear jig for the notebook shell of the utility model is as follows:

[0048] The operator adjusts the size of the retaining groove according to the size of the laptop shell in advance, then places the laptop shell in the retaining groove and firmly adsorbs the laptop shell into the retaining groove through vacuum adsorption. The operator holds the grinding assembly and then presses the grinding plate 20 against the fixing plate, sliding it along the upper surface of the fixing plate to grind away the burrs and protrusions on the surface of the laptop shell.

[0049] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
