[0023] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0024] Please refer to Figures 1 to 6. An embodiment of the present invention provides a fixture, including a base 1, a first rotating component 2 rotatably connected to the base 1, a support component 3 rotatably connected to the first rotating component 2, and an upper cover component 4 detachably connected to the support component 3. The support component 3 includes a support plate 31 rotatably connected to the first rotating component 2. The rotating axis between the first rotating component 2 and the base 1 is perpendicular to the rotating axis between the support plate 31 and the first rotating component 2. The first rotating component 2 can rotate relative to the base 1 to drive the support plate 31 to be horizontally arranged. The support plate 31 can rotate 2360° relative to the first rotating component. The support plate 31 is used to adsorb the product to be repaired. The upper cover component 4 is used to press the product to be repaired onto the support plate 31 when connected to the support component 3.

[0025] Since the first rotating assembly 2 can rotate relative to the base 1 to drive the support plate 31 to be set horizontally, when taking and placing the product to be repaired, the appearance of the product to be repaired can be facing the operator, and the product to be repaired can be taken and placed in parallel with both hands, which is convenient to operate, thereby reducing secondary and tertiary damage caused by taking and placing the product to be repaired; moreover, when repairing the side of the product to be repaired, since the support plate 31 can rotate 2360° relative to the first rotating assembly, the defective position of the side of the product to be repaired can be adjusted by rotating the support assembly 3, ensuring that the defective position of the side is adjusted to the optimal repair angle, thereby improving the success rate of repair. In addition, this fixture can simultaneously repair the appearance surface and the side of the product to be repaired, saving the cost of a set of fixtures, while reducing one pick-up and placement process, and reducing the risk of secondary defects.

[0026] It should be noted that during the repair process, the support plate 31 is first rotated upward along with the first rotating assembly 2 until the support plate 31 is horizontally arranged, and then the product to be repaired is placed on the support plate 31. The upper cover assembly 4 is then installed on the support plate 31 to press the product to be repaired onto the support plate 31, and the vacuum is started to allow the support plate 31 to adsorb the product to be repaired. After the product to be repaired is firmly adsorbed, the upper cover assembly 4 is removed. At this time, the appearance of the product to be repaired is facing the repairer, and the corresponding position is repaired. Alternatively, after the upper cover assembly 4 is installed on the support plate 31 to press the product to be repaired onto the support plate 31, the first rotating assembly 2 is rotated downward and the support plate 31 is rotated circumferentially to adjust the defective position of the side of the product to be repaired, thereby repairing the defective side and ensuring that there is no repair dead angle on the side. After the repair is completed, the support plate 31 is rotated upward along with the first rotating assembly 2 until the support plate 31 is horizontally arranged, and the product to be repaired is taken out at this time.

[0027] Referring to Figures 1, 2, and 3, the support assembly 3 also includes a base plate 32 that is rotatably mounted on the first rotating assembly 2 and fixedly connected to a support plate 31. The support plate 31 is located on the side of the base plate 32 away from the first rotating assembly 2. The side of the support plate 31 away from the base plate 32 is provided with a receiving cavity 311 for accommodating the product to be repaired. The support plate 31 can rotate upward with the first rotating assembly 2 until the support plate 31 is horizontally arranged. The receiving cavity 311 is adapted to the product to be repaired, and when the product to be repaired is accommodated in the receiving cavity 311, the appearance and side edges of the product to be repaired are exposed outside the receiving cavity 311 to ensure successful repair. The support plate 31 is provided with a plurality of adsorption holes 312 exposed in the receiving cavity. The adsorption holes 312 are used to adsorb and secure the product to be repaired in the receiving cavity 311.

[0028] Referring to Figures 2 and 3 , preferably, the base plate 32 is provided with a plurality of first through-holes 321 evenly distributed across the surface of the base plate 32. Providing a plurality of first through-holes 321 on the base plate 32 reduces its weight, facilitating the first rotating assembly 2 to rotate the base plate 32, thereby causing the support plate 31 to rotate with it. The base plate 32 and the support plate 31 are connected by fixing screws 35 . The base plate 32 is provided with countersunk holes, and the nut ends of the fixing screws 35 are mounted within the countersunk holes to prevent protrusions. Multiple fixing screws 35 are provided to ensure a secure connection between the base plate 32 and the support plate 31.

[0029] Referring to Figures 2, 3, and 4, the support assembly 3 also includes an adapter plate 33 fixed to the side of the support plate 31 near the base plate 32 and, together with the support plate 31, enclosing an air storage chamber 331. The air storage chamber 331 is connected to the suction holes 312. The adapter plate 33 is provided with an interface 332 that communicates with the air storage chamber 331 and is used to connect to a vacuum pump. Interface 332 can be a gas nozzle. When the vacuum pump is activated, the gas in the air storage chamber 331 is absorbed through interface 332, causing the air storage chamber 331 to be in a negative pressure state. This negative pressure causes the suction holes 312 to absorb and secure the product to be repaired.

[0030] Referring to Figures 2, 3, and 4, the support plate 31 is provided with a plurality of bosses 313, all located within the accommodating cavity 311 and spaced apart. The bosses 313 are arranged on the surface of the support plate 31 to form transverse grooves 314 and longitudinal grooves 315. Each adsorption hole 312 is located at the junction of the transverse grooves 314 and the longitudinal grooves 315. Specifically, the bosses 313 are arranged in an array within the accommodating cavity 311, so that the transverse grooves 314 and the longitudinal grooves 315 are arranged in an array. Since each adsorption hole 312 is located at the junction of the transverse grooves 314 and the longitudinal grooves 315, when vacuum is applied, the gas within the transverse grooves 314 and the longitudinal grooves 315 is extracted through the adsorption holes 312, thereby placing the entire support plate 31 in a negative pressure state, allowing the product to be repaired to be tightly adsorbed and adhered to the support plate 31.

[0031] Please refer to Figures 2 and 3. The support assembly 3 also includes a first protective block 34 that is detachably connected to the circumferential side of the support plate 31. A plurality of first protective blocks 34 are continuously distributed along the circumference. The first protective block 34 and the support plate 31 are detachably connected via flat-head screws. The first protective block 34 can be a metal protective block, which can prevent the support plate 31 from being worn due to excessive repair, thereby increasing the service life of the support plate 31. Moreover, the first protective block 34 is detachable and can be replaced individually after wear, greatly reducing costs. A positioning protrusion 316 is provided on the circumferential side of the support plate 31. The positioning protrusion 316 is provided on the side of the first protective block 34 away from the bottom plate 32. The positioning protrusion 316 is used to position the product to be repaired when it is placed in the accommodating cavity 311, so that the placement of the product to be repaired is more accurate.

[0032] Please refer to Figures 2 and 5. The upper cover assembly 4 includes a cover plate 41 that is detachably connected to the support plate 31 and a second protective block 42 that is detachably connected to the circumferential side of the cover plate 41. A plurality of second protective blocks 42 are continuously provided along the circumference. The cover plate 41 is used to cover the accommodating cavity 311 when connected to the support plate 31. Specifically, the second protective block 42 and the cover plate 41 are detachably connected by flat-head screws. The second protective block 42 can be a metal protective block, which can prevent the cover plate 41 from being worn due to excessive repair and increase the service life of the cover plate 41. Moreover, the second protective block 42 is detachable and can be replaced separately after wear, which greatly reduces costs. Among them, the cover plate 41 is provided with a handle 43 to facilitate the removal and placement of the cover plate 41; the cover plate 41 is provided with a plurality of second through holes 411. The provision of a plurality of second through holes 411 can reduce the weight of the cover plate 41.

[0033] It should be noted that when repairing the side, first lift the cover plate 41, then place the product to be repaired on the support plate 31, then apply vacuum so that the product to be repaired is adsorbed and secured to the support plate 31 through the adsorption holes 312, and then replace the cover plate 41. When repairing the exterior surface, first lift the cover plate 41, then place the product to be repaired on the support plate 31, then apply vacuum so that the product to be repaired is adsorbed and secured to the support plate 31 through the adsorption holes 312.

[0034] Referring to Figures 1 and 6 , the first rotating assembly 2 includes a connecting plate 21 rotatably connected to the base 1, a first sleeve 22 extending through both sides of the connecting plate 21 and fixed to the connecting plate 21, and a first rotating shaft 23 rotatably mounted within the first sleeve 22 and fixedly connected to the support assembly 3. The first rotating shaft 23 rotates about the first sleeve 22, and the support assembly 3 is sleeved on the outside of the first rotating shaft 23. Specifically, a bottom plate 32 is sleeved and fixed on the outside of the first rotating shaft 23, so that the support plate 31 rotates 360° about the first sleeve 22 following the first rotating shaft 23 under the drive of the bottom plate 32. The first sleeve 22 and the connecting plate 21 are fixed by screws. The first rotating shaft 23 is hollow and coaxially arranged with the first sleeve 22. The interface 332 on the adapter plate 33 is aligned with the central region of the first rotating shaft 23, allowing the air pipe to pass through the first sleeve 22 and the first rotating shaft 23 to connect with the interface 332, thereby preventing the air pipe from interfering with the rotation of the support plate 31.

[0035] Please refer to Figures 1 and 6. The base 1 includes a base 11 and a support frame 12 fixed to the base 11. The support frame 12 is provided with a horizontally arranged support platform 121 at one end away from the base 11. The connecting plate 21 is rotatably connected to the support frame 12, and when the connecting plate 21 rotates to be supported by the support platform 121, the support plate 31 is horizontally arranged. Specifically, there are two support frames 12, and the two support frames 12 are spaced apart on the base 11. The two ends of the connecting plate 21 are respectively rotatably connected to the two support frames 12 to ensure that the rotation of the connecting plate 21 is more stable. The support frame 12 is a triangular structure, and a through hole is provided in the middle of the support frame 12. The two support frames 12 are connected by a connecting rod 13, so that the connection between the two support frames 12 is more secure. The arc transition between the side of the support frame 12 and the support platform 121 is conducive to the up and down rotation of the connecting plate 21.

[0036] Referring to Figures 1 and 6 , the fixture further includes a second rotating assembly 5 mounted on the support frame 12 and rotatably connected to the connecting plate 21. The second rotating assembly 5 includes a second rotating shaft 51 rotatably mounted on the support frame 12 and a second shaft sleeve 52 sleeved and fixed around the circumference of the second rotating shaft 51 and fixedly connected to the connecting plate 21. The second shaft sleeve 52 rotates about the second rotating shaft 51. Specifically, each support frame 12 is provided with a second rotating assembly 5. The second shaft sleeve 52 is fixed to the plate surface of the connecting plate 21 and is disposed at one end of the second rotating shaft 51. The connecting plate 21 rotates up and down following the second shaft sleeve 52, thereby driving the support plate 31 to rotate up and down. The second rotating assembly 5 also includes a limit screw 53, which is fixed to the side of the support frame 12 away from the second sleeve 52. There are two limit screws 53, and the nuts of the two limit screws 53 are in contact with the end of the second rotating shaft 51 to limit the axial movement of the second rotating shaft 51; and the limit screw 53 is in contact with the second rotating shaft 51 to limit the left and right movement of the second rotating shaft 51 on the plate surface of the support frame 12, thereby preventing the second rotating shaft 51 from shaking too much.

[0037] The above is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the scope of protection of the present invention.
