Description

Technical Field

[0001] This utility model relates to the field of processing equipment, and in particular to a product processing equipment. Background Technology

[0002] In the manufacturing process of modern electronic products (such as tablets and smartphones), their structures are typically assembled from multiple precision components. Among these, metal parts, as key components, often require precision groove structures machined into their surfaces due to their unique structural complexity and decorative requirements. Traditional groove machining of metal parts typically employs CNC machining and grinding processes. CNC machining is too costly, while grinding presents significant technical challenges in practice: when high-speed grinding equipment comes into contact with the metal part, the workpiece is easily displaced or deflected due to mechanical forces, severely affecting machining accuracy. To ensure machining quality, the workpiece must be reliably fixed. While the commonly used clamping methods provide basic positioning, the thin-walled structure of electronic product metal parts often leads to irreversible plastic deformation, affecting the dimensional accuracy and appearance quality of the final product. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a product processing equipment to solve the problem that the existing thin sheet metal parts are prone to deformation during grinding when using clamping and fixing methods.

[0004] To solve the above-mentioned technical problems, the present invention provides a product processing equipment including a frame, a fixing mechanism located on the frame, and a grinding mechanism disposed on the frame. The fixing mechanism includes a first positioning structure for supporting and positioning the product in the horizontal direction and a second positioning structure disposed on the first positioning structure for picking up and positioning the product. The grinding mechanism is used to grind the corresponding structure at the grinding part of the product.

[0005] Furthermore, the first positioning structure includes a positioning protrusion adapted to the inner cavity of the product for covering and supporting the product thereon; the first positioning structure also includes a lower base located on the frame and an upper base mounted on the top surface of the lower base and having a supporting surface on the top surface, the positioning protrusion being formed by protruding upward from the supporting surface, and the second positioning structure being disposed within the upper base and the lower base and its top being used to pick up the product upward so that the product fits against the positioning protrusion.

[0006] Furthermore, the positioning protrusion has a recessed avoidance area corresponding to each protruding structure or groove on the inner cavity of the product to avoid it.

[0007] Furthermore, a central region is formed on the positioning protrusion and located inside each avoidance area. The second positioning structure includes an air cavity formed between the upper base and the lower base and a plurality of suction cups communicating with the air cavity. A plurality of receiving grooves are recessed on the central region corresponding to the plurality of suction cups. Each suction cup is disposed in a respective receiving groove, and the top of the suction cup extends upward through the receiving groove. When the suction cup holds the product and makes the product adhere to the positioning protrusion, the top is located in the receiving groove.

[0008] Furthermore, the outer edge of the positioning protrusion is formed with an outwardly open step portion to support part of the product. The first positioning structure also includes a positioning block formed on the support surface and located outside the positioning protrusion. The positioning block and the step portion enclose a positioning space for each side of the product to pass through.

[0009] Furthermore, the frame is provided with a transfer mechanism, and the first positioning structure is mounted on the transfer mechanism and used to drive it to move relative to the bottom of the grinding mechanism.

[0010] Furthermore, a lifting mechanism is provided on the frame corresponding to the grinding mechanism, and the grinding mechanism is connected to the lifting mechanism to drive the grinding mechanism to move up and down.

[0011] Furthermore, the frame is also provided with a protective part that faces the grinding mechanism, the lifting mechanism is installed on the protective part, and the grinding mechanism is located inside the protective part.

[0012] Furthermore, the protective part includes a base mounted on the frame and a protective cover fixedly connected to the base. A clearance space is formed on the bottom of the protective cover and on the side near the fixing mechanism along the moving direction of the first positioning structure. The clearance space communicates with the inner cavity of the protective cover. When the first positioning structure is located in the clearance space, the first positioning structure is located below the grinding mechanism.

[0013] Furthermore, the protective cover includes a support plate connected to the base, a top plate fixedly connected to the top of the support plate, and a first side plate and a second side plate distributed below the top plate and connected to the support plate along the moving direction of the first positioning structure; a rotating baffle is hinged to the side of the first side plate and the second side plate facing away from the support plate; an extended top plate adapted to the size of the two rotating baffles is formed on the top plate; when the two rotating baffles are rotated to be flush with the first side plate and the second side plate respectively, they contact the extended top plate and form a protective space between them; a grinding part of the grinding mechanism is located in the protective space; and the clearance space is formed at the bottom of the corresponding sides of the two rotating baffles and the protective cover.

[0014] The product processing equipment of this utility model has at least the following beneficial effects: by setting the first positioning structure, the product can be restricted in the horizontal direction while supporting the inner cavity of the product, dispersing pressure and stress during the grinding process and reducing the possibility of product deformation and movement; by setting the second positioning structure, the product is picked up from the inner side to position it, preventing the product from moving in the vertical direction, thereby achieving all-round positioning of the product without causing deformation of the product during the positioning process, thus greatly improving the service life of the product.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] Please see Figure 1 and Figure 2 One of the products adapted to this utility model is a tablet computer casing. Therefore, before processing, it already has a rectangular back plate b, side edges a integrally formed on the four sides of the back plate b, and an inner cavity formed by the side edges a and the back plate b. Protruding structures or groove-like structures c are formed on the back plate b and on one side of the inner cavity to facilitate subsequent injection molding. During processing, antenna slots need to be machined on the two side edges a of the outer side of the back plate b.

[0031] Please see Figures 3 to 11The product processing equipment of this utility model includes a frame 1, a fixing mechanism 2 mounted on the frame 1, a transfer mechanism 3 mounted on the frame 1 and cooperating with the fixing mechanism 2, a protective part 4 mounted on the frame 1, a lifting mechanism 5 mounted on the protective part 4, and a grinding mechanism 6 mounted on the lifting mechanism 5. The frame 1 is used to support other mechanisms and control the operation of each mechanism. The fixing mechanism 2 is used to position the product in all directions to prevent the product from moving during the grinding process and affecting the processing work and product quality. The transfer mechanism 3 is used to drive the fixing mechanism 2 relative to the grinding mechanism 6 to facilitate the automatic conveying of the product. The protective part 4 is used to prevent product debris from flying during the grinding process and ensure processing safety. The lifting mechanism 5 is used to drive the grinding mechanism 6 to lift and lower to facilitate the picking and placing of the product and the movement of the fixing mechanism 2. The grinding mechanism 6 is set on the frame 1 through the protective part 4 and the lifting mechanism 5 to grind the parts of the product that need to be ground, thereby grinding out the corresponding structure.

[0032] In another embodiment, the protective part 4 can be omitted, and the lifting mechanism 5 can be directly installed on the frame 1, which can also be used to drive the grinding mechanism 6 to move up and down. In yet another embodiment, the grinding mechanism 6 can be fixedly installed on the frame 1, and the lifting mechanism 5 can be set on the transfer mechanism 3, thereby driving the fixing mechanism to move up and down.

[0033] Please see Figure 3 In this embodiment, the frame 1 includes a frame body 11 with telescopic support legs 12 and casters 13 at the bottom, and an electrical control box 14 fixedly installed inside the frame body 11. A work panel 15 is fixedly installed on the top surface of the frame body 11. The top surface of the work panel 15 is horizontal, and all other mechanisms are installed on the work panel 15. An on / off switch is installed on the work panel 15. The on / off switch is electrically connected to the electrical control box 14 and each mechanism (including the transfer mechanism 3, the grinding mechanism 6, and the lifting mechanism 5). There can be one or more on / off switches, depending on actual needs, for starting and stopping each mechanism.

[0034] Please see Figures 3 to 9 In this embodiment, the fixing mechanism 2 includes a first positioning structure 21 for supporting and positioning the product in the horizontal direction, and a second positioning structure 22 disposed on the first positioning structure 21 for picking up and positioning the product. By supporting the inner cavity of the product, the possibility of deformation of the product during polishing is reduced, and some of the stress generated by the product during polishing is offset. At the same time, the horizontal movement of the product is restricted. Furthermore, by picking up the inner cavity of the product, the product can be positioned in the vertical direction, and the polishing process can be avoided. In another embodiment, the fixing mechanism 2 may include only the second positioning structure 22 or only the first positioning structure 21, both of which can achieve product positioning, or other structures with horizontal positioning and suction cup 222 can be used.

[0035] The first positioning structure 21 includes a positioning protrusion 211 adapted to the inner cavity of the product for covering and supporting the product, a lower base 212 located on the frame 1, an upper base 213 mounted on the top surface of the lower base 212 and having a support surface 215 on the top surface, and a positioning block 214 formed on the support surface 215 and located outside the positioning protrusion 211, wherein the positioning protrusion 211 is formed on the upper base 213. In this embodiment, four connecting posts 23 of equal height are formed at the center of the working panel 15. Both the lower base 212 and the upper base 213 are cuboid structures, and the length and width of the lower base 212 and the upper base 213 are the same and are stacked vertically. The four connecting posts 23 are fixedly connected to the four corners of the bottom surface of the lower base 212 in a rectangular array to support the lower base 212. The upper base 213 is connected to the top surface of the lower base 212, and the top surface of the upper base 213 is configured as the support surface 215. A positioning protrusion 211 protrudes upward from the support surface 215. The positioning protrusion 211 is located at the center of the support surface 215 and has a rectangular parallelepiped shape. The length and width of the positioning protrusion 211 are smaller than the length and width of the support surface 215, so that the support surface 215 retains an exposed portion around the positioning protrusion 211. The height of the positioning protrusion 211 is much greater than the thickness of the inner cavity of the product. Alignment areas 216 are recessed on the positioning protrusion 211 corresponding to the protruding structures and grooves on the inner cavity of the product to avoid unevenness in the support of the inner cavity during product positioning, thus preventing indentations. The protruding structures or grooves are concentrated at the edges of the product for subsequent injection molding, and are not located in the center. Therefore, to further facilitate the setting of the second positioning structure 22, a central region 2111 is formed on the positioning protrusion 211 and inside each avoidance region 216, so that the central region 2111 can provide main support when the product is supported on the positioning protrusion 211. Between the avoidance regions 216, a portion of the central region 2111 is still retained at the same height as the avoidance region 211 to facilitate further distributed support. A step 217 with an outward opening is formed around the outer edge a of the positioning protrusion 211 (i.e., the four sides a of the positioning protrusion 211) to support part of the product. The step 217 is formed by the edges of each central region 2111 and the portion of the positioning protrusion 211 at the same height as the central region 2111 relative to each avoidance region. The avoidance region 216 is open to the outward side in the horizontal direction, and the central region 2111 and the portion at the same height facing outward are arranged at a certain distance from the side a of the avoidance region to jointly form the step 217. The width of the step portion 217 is less than the thickness of the product side a. When the product is in use, it just covers or fastens onto the central region 2111 and the positioning protrusion 211 at the same height. The bottom inner side of each side a of the product is supported on the step portion 217.The positioning blocks 214 are fixedly installed on the support surface 215 by bolts and are configured in multiple ways. The rear shell of the positioning blocks 214 is configured in eight ways. Two positioning blocks 214 are set for each side a of the support surface 215. The positioning blocks 214 are spaced apart and the distance between them and the positioning protrusions 211 is greater than the thickness of the product side a. This is to make the positioning blocks 214 and the side a of the positioning protrusions 211 spaced apart. A positioning space 24 is formed between the positioning blocks 214 and the step portion 217 for the side a of the product to pass through. The positioning space 24 enables the product to quickly align with the positioning protrusions 211. To facilitate product placement and removal, a placement and removal groove 218 is recessed on each side a of the support surface 215 at a position between the two positioning blocks 214 on the corresponding side a. The groove surface of the placement and removal groove 218 is lower than the bottom surface of the step portion 217, and the placement and removal groove 218 extends horizontally outward through the upper base 213, so that when the product is positioned on the positioning protrusion 211, the middle part of each side a is suspended in the placement and removal groove 218.

[0036] The second positioning structure 22 is disposed within the upper base 213 and the lower base 212, and its top is used to suction the product upwards so that the product fits against the positioning protrusion 211. The second positioning structure 22 includes an air cavity 221 formed between the upper base 213 and the lower base 212 and a plurality of suction cups 222 communicating with the air cavity 221. A groove is recessed on the top surface of the lower base 212, and the upper base 213 is stacked on top of the top surface of the lower base 212 to block the opening side of the groove. A sealant is provided between the upper base 213 and the lower base 212 so that the upper base 213 and the groove together form the air cavity 221. A plurality of receiving grooves 223 are recessed in the central region 2111 in the same number as the plurality of suction cups 222. Each suction cup 222 is disposed in a respective receiving groove 223, and the top of the suction cup 222 extends upwards through the receiving groove 223. The receiving groove 223 has a cylindrical structure, and a through hole 224 is provided on the bottom wall of the receiving groove 223, which connects the receiving groove 223 and the air cavity 221. The suction cup 222 is fixedly connected in the receiving groove 223 and has an air suction hole that connects to the through hole 224. The air suction hole of the suction cup 222 extends axially through the suction cup 222, and the flared nozzle of the suction cup 222 protrudes upward from the top surface of the central region 2111. When the product is pressed onto the positioning protrusion 211, the suction cup 222 sucks up the product and fits tightly against the inner cavity wall of the product. The product fits against the top surface of the positioning protrusion 211. At this time, the suction nozzle of the suction cup 222 is located in the receiving groove 223, thus ensuring that the product is supported by the positioning protrusion 211 while sucking up the product. It should be noted that the air chamber 221 is connected to an external air source and the connection and disconnection of the external air source are controlled by the electrical control box 14.

[0037] Please see Figures 3 to 8The transfer mechanism 3 includes a linear motion unit mounted on the work panel 15. The linear motion unit is either an electric linear guide or a linear module, both having a first slider 32 that slides back and forth electrically. The linear motion unit can be configured with a first guide 31, a first slider 32 slidably mounted on the first guide 31, a first motor 33 mounted at the end of the first guide 31, and a first screw shaft connected to the motor output end. The end of the first screw away from the motor is rotatably connected to the first guide 31, and the first screw is arranged parallel to the first guide 31. The bottom of the first slider 32 is threaded onto the first screw, causing the output shaft of the motor to rotate in both directions, thus driving the slider to move back and forth. The entire transfer mechanism 3 is mounted below the lower base 212 and inside the two connecting posts 23. Each connecting post 23 is positioned on either side of the transfer mechanism 3. The lower base 212 of the first positioning structure 21 is fixedly connected to the top of the first slider 32, enabling the transfer mechanism 3 to drive the fixing mechanism 2 to move back and forth relative to the grinding mechanism 6. To ensure the movement of the entire fixed mechanism 2, second guide rails 34 connected to the work panel 15 are installed on both sides of the transfer mechanism 3. Two second sliders 35 are slidably arranged on each of the two second guide rails 34. The two second guide rails 34 are arranged parallel to the electric linear guide. Two connecting posts 23 are respectively connected to the two second sliders 35 of one of the second guide rails 34, and the other two connecting posts 23 are respectively connected to the two second sliders 35 of the other second guide rail 34, so that the first slider 32 can drive the entire fixed mechanism 2 to move when the electric linear guide is running. It should be noted that an initial block and a working block can be set on the second guide rails 34. When the connecting post 23 contacts the initial block, it indicates that the fixed mechanism 2 is not below the grinding structure. When the connecting post 23 contacts the working block, the fixed mechanism 2 moves to the bottom of the grinding mechanism 6, thereby limiting the movement position of the fixed mechanism 2. Alternatively, the initial block and working block can be omitted, and two sensors can be set on the second guide rails 34 to detect the approach or contact of the fixed mechanism 2, thereby controlling the start and stop of the transfer mechanism 3. In another embodiment, the transfer mechanism 3 may include two fourth guide rails, a fourth slider disposed on the two fourth guide rails, a support plate 421 fixedly connected to each fourth slider, and a cylinder disposed on the working panel 15 and connected to the piston fixed plate. The cylinder is arranged parallel to the fourth guide rails along its axis. The fixing mechanism 2 is mounted on the support plate 421 so that the cylinder can drive the fixing mechanism 2 to move by extension and retraction.

[0038] In this embodiment, in order to grind the antenna slots on both sides of the product at the same time, the protective part 4, the grinding part 62 and the lifting part are all set in two. One protective part 4, the grinding part 62 and the lifting part are the first group, and the other protective part 4, the grinding part 62 and the lifting part are the second group. The first group and the second group are spaced apart on both sides of the transfer mechanism 3 along the separation direction of the two second guide rails 34.

[0039] Please see Figures 3 to 6 , Figure 10 and Figure 11 The protective unit 4 includes a base 41 mounted on the work panel 15 and a protective cover 42 fixedly connected to the base 41. The base 41 provides connection support for the protective cover 42, which is used to cover the outside of the grinding mechanism 6 to avoid the adverse effects caused by flying debris during the grinding process. The base 41 is fixedly mounted on the work panel 15 by bolts, and the base 41 and the second guide rail 34 are spaced apart and do not interfere with each other. A clearance space 426 is formed at the bottom of the protective cover 42 and on the side near the fixing mechanism 2 (i.e., the bottom of the side of the first and second sets of protective covers 42 facing inward) along the moving direction of the first positioning structure 21. The clearance space 426 is connected to the inner cavity of the protective cover 42. When the first positioning structure 21 moves toward the side where the clearance space 426 is located and enters the clearance space 426, the first positioning structure 21 is located below the grinding mechanism 6. The grinding mechanism 6 cooperates with the lifting mechanism 5 to grind the product. When the grinding is completed, the transfer mechanism 3 drives the fixing mechanism 2 to move toward the other side, so that the fixing mechanism 2 and the product gradually move out of the clearance space 426.

[0040] The protective cover 42 includes a vertically arranged support plate 421 connected to the base 41 at its bottom, a top plate 422 fixedly connected to the top of the support plate 421 and extending horizontally inward, and a first side plate 423 and a second side plate 424 distributed below the top plate 422 and connected to the support plate 421 along the moving direction of the first positioning structure 21. The support plate 421, top plate 422, first side plate 423 and second side plate 424 together form a cuboid cavity structure that is open inward and downward. To reinforce the support plate 421, a first reinforcing block 43 is fixedly connected to the support plate 421 on its outward side. The width of the support plate 421 is parallel to the moving direction of the fixing mechanism 2, and the length of the support plate 421 is arranged vertically. A second reinforcing block 44 can also be used to reinforce the top plate 422 and the support plate 421, with the inward side of the top plate 422 extending beyond the second reinforcing block 44. The first side plate 423 and the second side plate 424 are connected to the two long sides of the support plate 421 along its width. The side of the first side plate 423 and the second side plate 424 closest to the support plate 421 is supported on the base 41, while the other side of the first side plate 423 and the second side plate 424 facing inward is suspended outside the side of the base 41 facing inward and close to the second guide rail 34. A rotating baffle 45 is hinged to the side a of the first side plate 423 and the second side plate 424 facing away from the support plate 421. The rotating baffle 45 is hinged to the corresponding side plate by a hinge. An extended top plate 4221 adapted to the size of the two rotating baffles 45 is formed on the top plate 422. The two rotating baffles 45 are respectively closer to or further away from the inner cavity of the protective cover 42 along the moving direction of the fixing mechanism 2 relative to the first side plate 423 and the second side plate 424. When the two rotating baffles 45 are rotated to be flush with the first side plate 423 and the second side plate 424 respectively, they contact the extended top plate 4221 and form a protective space between them. The grinding part 62 of the grinding mechanism 6 is located in the protective space, which can block the grinding mechanism 6 and prevent the grinding mechanism 6 from splashing debris during the grinding process. The clearance space 426 is formed at the bottom of the first side plate 423 and the second side plate 424 of the two rotating baffles 45 and the protective cover 42. When it is necessary to maintain the grinding part 62 of the grinding mechanism 6, the rotating baffles 45 can be rotated to the outside of the protective cover 42, and the grinding part 62 is located outside the protective cover 42. An L-shaped notch 425 is formed at the bottom of the first side plate 423 and the rotating baffle 45 hinged thereto. Similarly, an L-shaped notch 425 is formed at the bottom of the second side plate 424 and the rotating baffle 45 hinged thereto. The two L-shaped notches 425 are connected along the moving direction of the fixing mechanism 2. When the fixing mechanism 2 moves, it passes through the L-shaped notches 425 to enter the clearance space 426, and the two L-shaped notches 425 are configured as part of the clearance space 426.

[0041] Please see Figures 3 to 6 , Figure 10 and Figure 11The lifting mechanism 5 includes a second motor 51 mounted on a top plate 422 with its output shaft vertically passing through the top plate 422 and the second reinforcing block; a second screw 52 connected to the motor output shaft and located inside a protective cover 42; two third guide rails 53 mounted inside the protective cover 42 and each having two third sliders 54; a guide sleeve screwed onto the second screw 52; and a mounting plate 55 fixedly connected to the guide sleeve. The second motor 51 is a second motor with an output shaft capable of forward and reverse rotation. A bearing (not shown in the figure) is fixedly mounted on the second reinforcing block. The inner ring of the bearing vertically passes through the second reinforcing block 44 and the top plate 422. The output shaft of the second motor 51 and the second screw 52 are both fixedly connected to the inner ring of the bearing so that they can rotate relative to the second reinforcing block 44. In another embodiment, the second motor 51 can be replaced by a manual turntable, and the lifting of the grinding mechanism 6 can be completed by manual rotation. Two reinforcing strips 46 are also provided inside the protective cover 42. Each side plate of the two reinforcing strips 46 is connected to the support plate 421, the top plate 422, and the base 41, respectively. The two reinforcing strips 46 are respectively arranged in contact with the first side plate 423 and the second side plate 424. Two third guide rails 53 are respectively connected to the inward side a of the two reinforcing strips 46 to provide support for the third guide rails 53. The second screw 52 and the guide sleeve are both located between the two reinforcing strips 46. The guide sleeve is coaxial with the second screw 52 and has a screw hole (not shown in the figure). The second screw 52 passes through the screw hole so that the guide sleeve is screwed onto the second screw 52. The mounting plate 55 has an L-shaped structure with a horizontally arranged first section 551 and a vertically arranged second section 552. The two sides of the mounting plate 55 are spaced apart from the first side plate 423 and the second side plate 424. Third reinforcing blocks are connected to the sides of the first section 551 and the second section 552. The second segment 552 is fixedly connected to the two third sliders 54 on the two third guide rails 53, so that the mounting plate 55 cannot rotate. In another embodiment, the lifting mechanism 5 may only drive the linear guide rail, and is not limited to the structure of this embodiment.

[0042] In use, the operation of the second motor 51 drives the second screw 52 to rotate. The guide sleeve is threaded together, and the mounting plate 55 cannot rotate, so the mounting plate 55 moves up and down in the vertical direction with the guide sleeve. The grinding mechanism 6 is installed on the mounting plate 55 so that the lifting mechanism 5 can drive the grinding mechanism 6 to move up and down.

[0043] Please see Figures 3 to 6 , Figure 10 and Figure 11The grinding mechanism 6 is located inside the protective part 4. The grinding mechanism 6 includes a high-power motor 61 with a high-speed rotating output shaft and a grinding part 62 connected to the end of the output shaft of the high-power motor 61. The grinding part 62 is arranged inward along the thickness direction of the support plate 421 (towards the fixing mechanism 2). The top of the high-power motor 61 is fixedly mounted on the first section 551 of the mounting plate 55. The grinding part 62 includes a circular grinding blade for grinding structures such as antenna slots on the product. When the lifting mechanism 5 moves the grinding mechanism 6 downward to the bottom, the bottom of the grinding part 62 is located within the clearance space 426. When the lifting mechanism 5 moves the grinding mechanism 6 upward to the top, the bottom of the grinding part 62 is above the clearance space 426 and not within it. It should be noted that the grinding mechanism 6 can be any device capable of grinding a product, and is not limited to the structure shown in this utility model.

[0044] One embodiment of the product processing equipment of this utility model operates as follows: Initially, the fixing mechanism 2 is located outside the clearance space 426, and the lifting mechanism 5 positions the grinding part 62 of the grinding mechanism 6 above the clearance space 426; after the inner cavity of the product faces the positioning protrusion 211, the product is placed on the middle area 2111 of the positioning protrusion 211. After slightly pressing down on the product, the suction nozzle of the suction cup 222 is pressed against the cavity wall of the inner cavity, so that each side a of the product is located in the positioning space 24 and formed on the step 217. After the electrical control box 14 connects to the external air source to suck up the product, the transfer mechanism 3 is started. The operation of the transfer mechanism 3 drives the fixing mechanism 2 and the product to move inward. After the fixing mechanism 2 and the product pass through the first L-shaped notch 425, the two sides a of the product that need to be processed move into the two clearance spaces 426 and are in place. Then, the lifting mechanism 5 drives the mounting plate 55 to move downwards until the bottom of the grinding part 62 moves into the clearance space 426. The high-power motor 61 runs to grind the product. During the grinding process, the transfer mechanism 3 will still drive the fixing mechanism 2 to move as needed so that the grinding part 62 can grind to different positions until the antenna slot of the product is processed. Then, the high-power motor 61 stops running, the lifting mechanism 5 drives the mounting plate 55 to reset, and then the transfer mechanism 3 drives the fixing mechanism 2 and the product to reset so that the product can be removed.

[0045] Compared with the prior art, the product processing equipment of this utility model can achieve omnidirectional positioning of the product, and reduce the possibility of damage and deformation to the product side a and back plate b during the positioning process; the protective cover 42 design can not only prevent debris from flying, but also does not hinder the processing and movement of the product, and protects the grinding part 62 to a certain extent; the design of two sets of grinding mechanisms 6 can shorten the processing time and improve the processing efficiency.
