[0022] Example:

[0023] In order to solve the above-mentioned problems in the related art, this embodiment provides a supporting jig.

[0024] As shown in Figures 1-4, in this embodiment, the support jig is used to fix the shell component during the deburring process of the shell component. The support jig includes a main body 1, which is connected to a limiting edge 113 protruding from the top edge of the main body 1, and an air suction portion 1121 located at the top of the main body 1 and spaced from the inner side of the limiting edge 113, and an air suction groove 1121a is provided in the air suction portion 1121; an assembly space for fixing the shell component is formed between the limiting edge 113 and the air suction portion 1121.

[0025] Specifically, in this embodiment, the shell component may refer to laptop shell A (the shell corresponding to the back of the display screen). That is, the support jig in this embodiment can be used to assist in deburring the inner cavity of laptop shell A. Of course, in some other embodiments, the shell component may also be laptop shell D (the shell corresponding to the bottom of the body), which is not limited here. An assembly space for fixing the shell component is formed between the limiting edge 113 and the suction portion 1121. That is, the height of the suction portion 1121 is less than the height of the limiting edge 113. The suction portion 1121 is located on the bottom side of the limiting space and can provide support for the shell component, preventing the entire exterior surface of the laptop shell A from directly contacting the support jig, thereby reducing the risk of three damages to the product. The suction groove 1121a of the suction portion 1121 can also be connected to an external suction device to generate negative pressure with the shell component, thereby sucking the shell component and ensuring the fixed stability of the shell component during processing. The provision of the limiting edge 113 can position the shell component and effectively limit the horizontal displacement of the shell component, further improving the fixed stability of the laptop shell A.

[0026] In this embodiment, the limiting edge 113 can respectively abut against each side of the notebook shell A to position the notebook shell A in the horizontal direction. The limiting edge 113 can be an integrally connected annular limiting edge 113, or specifically a U-shaped annular limiting edge; or it can be multiple limiting edges 113 spaced apart and distributed outside the assembly space, without limitation. Furthermore, in this embodiment, at least four spaced positioning platforms 1131 are formed on the side of the limiting edge 113 facing the air intake portion 1121. Each positioning platform 1131 is used to abut against each circumferential side of the shell component during the deburring process. Preferably, eight spaced positioning platforms 1131 can be provided, that is, two positioning platforms 1131 are spaced apart on each of the four sides of the assembly space. This allows the notebook shell A to be positioned from four directions, and reduces the contact area between the limiting edge 113 and the side of the notebook shell A, which is beneficial to improving product quality.

[0027] In this embodiment, the main body 1 includes a support plate 11 with an air suction portion 1121 and a limiting portion connected to the top, and a frame 12 fixed to the bottom side of the support plate 11. The frame 12 can support the support plate 11 and fix it to the external environment equipment. The support plate 11, the air suction portion 1121, and the limiting edge 113 can be obtained in an integrally formed manner. An air flow channel (not shown in the figure) connecting the air suction groove 1121a and the external air suction device can also be provided in the support plate 11, so that after the shell device is placed in the assembly space, the shell device can be sucked and fixed by the external air suction device, and the fixing effect is good. One or more air suction portions 1121 can be provided, and one or more air suction grooves 1121a can be provided on each air suction portion 1121, preferably two, which are not limited here.

[0028] In this embodiment, the main body 1 further includes a nozzle 3 fixed to the top of the frame 12. A clearance opening 11a and drainage holes 11b arranged around the periphery of the clearance opening 11a are defined within the support plate 11. The nozzle 3 extends from the frame 12 through the clearance opening 11a to the assembly space. A drainage groove 121b is provided on the top of the frame 12, corresponding to the position of the drainage hole 11b. The nozzle 3 sprays water during the deburring process, effectively preventing dust hazards associated with the deburring process. The water ultimately flows through the drainage holes 11b and into the drainage groove 121b.

[0029] Furthermore, in this embodiment, the support plate 11 includes a middle portion 111 and a slope portion 112 arranged around the outer peripheral side of the middle portion 111. The angle between the side of the slope portion 112 facing the assembly space and the plane where the middle portion 111 is located is 0.5°~3°, and the drainage hole 11b is located at the connection between the middle portion 111 and the slope portion 112. Specifically, the middle portion 111 is parallel to the horizontal plane, and the top surface of the slope portion 112 gradually tilts downward from the limiting edge 113 to the middle portion 111, that is, a certain slope is formed to facilitate the flow of water into the drainage groove 121b. Preferably, the angle between the side of the slope portion 112 facing the assembly space and the plane where the middle portion 111 is located can be 1.5°. Of course, the angle can also be set to 1° or 2°, etc., which is not limited here. The top surface of the slope portion 112 can be composed of four slopes connected in sequence. It is understood that in other embodiments, the top surface of the slope portion 112 can also be set as an arc-shaped slope, which is not limited here. One or more drainage holes 11b can be provided, and the shape of the drainage hole 11b can be arc-shaped, circular, square, etc. Preferably, the drainage hole 11b can include four elongated drainage holes corresponding to the four slopes respectively. The position and number of the drainage grooves 121b are adapted to the drainage holes 11b, the structure is simple, and can meet the requirements of timely drainage.

[0030] In this embodiment, at least four spaced and symmetrical suction portions 1121 are arranged around the side of the slope portion 112 facing the assembly space, that is, each suction portion 1121 is connected to the top surface of the slope portion 112; the end surface of each suction portion 1121 is parallel to the plane where the middle portion 111 is located, so that the corresponding areas of the shell component can be evenly and firmly adsorbed during processing. Preferably, a suction portion 1121 can be set at each of the four corners of the top surface of the support plate 11, and a suction portion 1121 can be set at each of the positions near the middle of the two long straight sides of the top surface of the support plate 11. In this way, the six suction portions 1121 can form a strong adsorption fixation for the shell component.

[0031] In this embodiment, a protective block 4 is further connected to the side of the limiting edge 113 that faces away from the assembly space. The provision of the protective block 4 can prevent the product from being over-worn due to excessive removal during deburring. The outer side of the limiting edge 113 and the outer side of the edge at the top of the support plate 11 are connected to form a mounting groove 1122. The shape of the protective block 4 is exactly adapted to the shape of the limiting groove, so that when the protective block 4 is installed in the mounting groove 1122, it fits and is fixed to the outer side of the limiting edge 113 and the outer side of the edge at the top of the support plate 11. A threaded hole can also be provided at the bottom of the mounting groove 1122 (the outer side of the edge at the top of the support plate 11), and the protective block 4 and the mounting groove 1122 can be reinforced and fixed by a threaded connection. Furthermore, in this embodiment, the protective block 4 includes a straight edge portion 41 connected to the limiting edge 113, and a chamfered portion 42 connected to the limiting edge 113 and detachably fixed to both ends of the straight edge portion 41. During machining, the straight edge 41 protects the straight edges of the laptop's case A, while the chamfered portion 42 protects the corners, preventing excessive burr removal. The straight edge 41 and chamfered portion 42 are detachably connected, making it easier for users to partially or completely replace the protective block 4 depending on the jig's operating conditions, thus saving costs.

[0032] In this embodiment, the frame 12 includes a fixed plate 121 fixed to the bottom side of the support plate 11, at least two vertical plates 122 spaced apart from each other and fixed to the side of the fixed plate 121 facing away from the support plate 11, and a base 123 connected and fixed to one end of each vertical plate 122 facing away from the fixed plate 121. Specifically, a mounting hole can be provided on the base 123, and the base 123 can be fixed to the external environment equipment through the mounting hole. Two vertical plates 122 can be provided, and the two vertical plates 122 are respectively perpendicular to and fixed to the two ends of the base 123, and the side surfaces of the two vertical plates 122 are aligned with the side surfaces of the base 123, thereby forming support for the fixed plate 121 and the support plate 11. A fixing hole 121a for fixing the nozzle 3 is provided in the center of the fixing plate 121, and a drainage groove 121b is provided on the periphery of the fixing hole 121a to spray water during the deburring process to prevent dust hazards. Furthermore, the support plate 11 and the fixed plate 121 , the fixed plate 121 and the vertical plate 122 , and the vertical plate 122 and the base 123 can be fixed by threaded connections, which makes installation simple and improves the stability of the frame 12 .

[0033] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
