[0028] Electroplating is a process that uses the principle of electrolysis to plate a layer of another metal or alloy onto a metal surface. During electroplating, electroplating equipment is typically used. Some electroplating equipment is a spot plating machine, in which pre-cut metal parts are positioned on the machine using fixtures to shield certain areas of the part from the plating process.

[0029] Modern wheel-type spot plating equipment uses a water pump connected to a mounting shaft to supply liquid to a fan-shaped spraying component, which then sprays the plating solution onto the circumferential surface of a rolling wheel for electroplating.

[0030] As electronic devices become smaller, the cut metal parts are also smaller, making loading inconvenient and impacting plating efficiency. Furthermore, current plating equipment, particularly wheel-type electroplating machines, suffers from localized stagnation of the plating solution within the fan-shaped spray pattern after prolonged plating. This results in slight variations in the concentration of the sprayed plating solution, leading to defective products.

[0031] Please refer to the attached document. Figure 1 The present invention provides a wheel-type spot plating device, comprising: a wheel body 10, wherein a mounting shaft 11 is provided at the axial center of the wheel body 10, and a bearing is provided between the wheel body 10 and the mounting shaft 11; At least one fixture 13 is detachably and evenly distributed on the wheel body 10 for placing products; The spraying component is fixed on the mounting shaft 11. The inner wall of the spraying component has a liquid storage cavity. The mounting shaft 11 is connected to the liquid supply system and supplies liquid to the liquid storage cavity through the liquid outlet 111. The spraying port of the spraying component is located at the position of the fixture 13 corresponding to the wheel body 10. The outlet center of the liquid outlet 111 forms an angle with the spray center of the spraying element, and the angle is controlled to be 20-45°.

[0032] It should be noted that the liquid supply system includes a water pump, a liquid supply pipeline, and a liquid supply tank. The water pump is connected to the liquid supply tank through the liquid supply pipeline. The liquid supply tank contains a certain amount of electroplating solution. The water pump draws electroplating solution from the liquid supply tank and supplies it to the spraying component through the liquid supply pipeline. Here, the water pump ensures that the supplied electroplating solution has a certain pressure so that the electroplating solution can be sprayed outward from the spraying component. The pressure can be changed according to the different water pumps used. In this embodiment, the pressure only needs to be enough to spray the electroplating solution from the spraying component to the electroplating position, i.e., the position corresponding to fixture 13. This will not be elaborated further. At the same time, the electroplating solution sprayed to the electroplating position by the spraying component can be recycled and reused. There are usually conventional electroplating solution recycling systems. The recycling system includes devices for filtering impurities and replenishing concentration, etc., which can be referred to as conventional electroplating solution recycling systems. This will not be elaborated further.

[0033] In this embodiment, by tilting the outlet of the liquid outlet 111 to one side, specifically, after installation with the wheel body 10, the liquid outlet 111 is tilted towards the lower position of the liquid storage cavity of the spraying component. This ensures that the liquid outlet 111, when supplying liquid, agitates the electroplating solution in the liquid storage cavity through the pressure brought by the water pump. In other words, it ensures that the electroplating solution in the liquid storage cavity is in a flowing state, avoiding the problem of the electroplating solution at the bottom not flowing for a long time after entering the liquid storage cavity, which would cause slight differences in concentration. This effectively ensures the consistency of the electroplating solution concentration, ensures the quality of electroplating, and improves the yield.

[0034] In this embodiment, the wheel-type spot plating device includes a wheel body 10, a fixture 13, and a spraying element 12. The wheel body 10 and the spraying element 12 are connected and installed via a mounting shaft 11, allowing the wheel body 10 to rotate relative to the spraying element 12. At least one fixture 13 is detachably mounted on the outer surface of the wheel body 10. The fixture 13 is used to place and position the product, thereby ensuring continuous localized electroplating of the product to be processed on the wheel body 10 and improving processing efficiency. Furthermore, by making the fixture 13 detachable, a suitable fixture 13 can be replaced according to the actual product structure to be plated, ensuring that the wheel-type spot plating device can adapt to more products, improving adaptability and reducing equipment production costs. By adjusting the position of the liquid outlet 111 of the mounting shaft 11, the electroplating solution in the liquid storage chamber of the spraying element flows, preventing sedimentation caused by stagnant electroplating.

[0035] In actual operation, the fixture 13 corresponding to the product to be electroplated is installed on the wheel body 10, and then the product to be processed is placed on the fixture 13 of the wheel body 10. The wheel body 10 can rotate relative to the mounting shaft 11. When the product follows the rotation of the wheel body 10 to reach the position corresponding to the spraying element 12, the spraying element 12 continuously sprays electroplating liquid, so that electroplating can be performed by spraying electroplating liquid onto the product through the spraying element 12.

[0036] Reference Appendix Figure 2 As shown, in some embodiments, the outlet center of the liquid outlet 111 forms an angle with the spray center of the spraying element, that is, the outlet centerline P of the liquid outlet 111 and the spray center H of the spraying element form an angle D, and the angle D is controlled to be 30°; in some embodiments, the outlet center of the liquid outlet 111 and the spray center of the spraying element form an angle, that is, the outlet centerline P of the liquid outlet 111 and the spray center H of the spraying element form an angle D, and the angle D is controlled to be 20°; in some embodiments, the outlet center of the liquid outlet 111 and the spray center of the spraying element form an angle, that is, the outlet centerline P of the liquid outlet 111 and the spray center H of the spraying element form an angle D, and the angle D is controlled to be 45°.

[0037] Reference Appendix Figure 11 As shown in the embodiment, the mounting shaft 11 is a hollow tube, which is provided with a liquid inlet 112, a liquid outlet 111 and an isolation member 110. The liquid inlet 112 is located at one end of the hollow tube and is used to connect to the liquid supply system. The liquid outlet 111 is located on the side wall of the hollow tube and communicates with the inner cavity 113 of the hollow tube. The isolation element 110 is located in the inner cavity 113 and isolates the liquid inlet 112 and the liquid outlet 111 in the same inner cavity 113.

[0038] Understandably, by setting the mounting shaft 11 as a hollow tube with a hollow structure, and providing a liquid outlet hole 111 on the side wall of the hollow tube, the liquid outlet hole 111 is connected to the liquid storage cavity of the spraying component, and the interior of the hollow tube is divided into two parts by the isolation member 110, and the liquid inlet hole 112 and the liquid outlet hole 111 are located in the same inner cavity 113 of the hollow tube.

[0039] Reference Appendix Figure 11 As shown in the embodiment, the isolation member 110 is configured to gradually slope from the liquid outlet 111 to the liquid inlet 112 to ensure that the electroplating solution is smoothly ejected from the liquid outlet 111 after passing through the liquid inlet 112.

[0040] To ensure that the electroplating solution can be smoothly and quickly ejected from the sprayer, the embodiment uses an inclined isolation member 110 to guide the electroplating solution to quickly pass through the inside of the hollow tube and be ejected from the outlet hole 111.

[0041] Reference Appendix Figure 12 As shown in the embodiment, the lateral size of the liquid outlet 111 gradually decreases from the inner cavity 113 of the hollow tube to the outer surface.

[0042] Understandably, in order to further improve the fluidity within the storage cavity, in this embodiment, the structure of the outlet hole 111 is set as a gradient structure. Specifically, the cross-section of the outlet hole 111 gradually decreases from near the storage cavity towards the outer surface of the hollow tube, that is, the liquid storage capacity of the outlet hole 111 gradually decreases, thereby increasing the intensity of the electroplating solution sprayed from the outlet hole 111, effectively agitating the electroplating solution within the storage cavity, and ensuring that the electroplating solution settles inside the storage cavity.

[0043] In this embodiment, the pressure of the liquid injection is increased by gradually changing the liquid output from the liquid outlet 111.

[0044] Please refer to the attached document. Figure 1 and 3 In a further embodiment, the wheel body 10 includes a roller body 102, which is a tubular structure and has at least one mounting position 103 on the tube wall; The first side mounting 100 is detachably mounted at one end of the roller body 102; The second side mount 101 is detachably disposed at the other end of the roller body 102, and the first side mount 100 and the second side mount 101 are connected to the mounting shaft 11.

[0045] Understandably, in this embodiment, the wheel 10 includes a roller 102, a first side mount 100, and a second side mount 101. The roller 102 is a tubular structure, with its two ends connected to the first side mount 100 and the second side mount 101, respectively. The first side mount 100 and the second side mount 101 are movably connected to the mounting shaft 11, and mounting positions 103 are provided on the wall of the tubular structure for mounting the fixture 13. The roller 102, the first side mount 100, and the second side mount 101 form a cavity, and the spraying element 12 is installed inside this cavity. That is, the spraying element 12 can spray electroplating solution onto the inner wall of the rotating tubular structure, thereby electroplating the product on it. In this embodiment, this design ensures the structural stability of the wheel 10 and makes installation more convenient.

[0046] In a further embodiment, the roller body 102 has at least one recessed structure 1012 on the side near the second side mounting member 101, and the second side mounting member 101 has at least one protruding structure 1011 on the side, wherein the recessed structure 1012 cooperates with the protruding structure 1011.

[0047] In a further embodiment, the recessed structure 1012 is evenly distributed along the periphery of the roller body 102, and the recessed structure 1012 gradually deepens from one side to the other along the periphery of the roller body 102.

[0048] In this embodiment, to reduce the difficulty of installing the wheel 10, a recessed structure 1012 is provided on the side of the roller 102 near the second side fitting 101, and it cooperates with the protruding structure 1011 of the second side fitting 101. The recessed structure 1012 has a gradually deepening structure. This allows for effective and rapid positioning when installing the roller 102 and the second side fitting 101, and the gradual structure further ensures the connection between the roller 102 and the second side fitting 101 during rolling. That is, the cooperation between the protruding structure 1011 and the recessed structure 1012 prevents loosening.

[0049] In this embodiment, the recessed structure 1012 gradually deepens from one side to the other along the periphery of the roller body 102. The recessed structure 1012 gradually deepens inward along the direction of rotation of the wheel body 10. The gradually deepening structure allows the matching protruding structure 1011 to be quickly positioned and matched during installation.

[0050] For example: In one embodiment, four recessed structures 1012 are evenly arranged on the side of the roller body 102, and are arranged along the direction of rotation of the roller body 10, that is, the recessed structures 1012 gradually become deeper along the direction of rotation of the roller body 10. The protruding structures 1011 are set as gradually protruding structures 1011. After installation, the recessed structures 1012 and the protruding structures 1011 cooperate with each other. During operation, external power drives the second side mounting component 101, which drives the roller body 102 to rotate. The protruding structures 1011 drive the recessed structures 1012, effectively ensuring the stability of rotation.

[0051] In a further embodiment, the wheel body 10 also includes bearings (not shown in the figure), which are respectively disposed at the positions where the first side mount 100 and the second side mount 101 are connected to the mounting shaft 11.

[0052] Understandably, in order to ensure that the wheel body 10 can rotate relative to each other, in this embodiment, a bearing is provided at the position where the wheel body 10 is connected to the mounting shaft 11 to ensure that the wheel body 10 can rotate smoothly. Specifically, bearings are provided at the positions where the first side mounting part 100 and the second side mounting part 101 are respectively connected to the mounting shaft 11.

[0053] Please refer to the attached document. Figure 5 In a further embodiment, the second side mount 101 is provided with a transmission structure 1010, which is located near the mounting position 103.

[0054] Understandably, in order to ensure that the wheel 10 can still rotate relative to the mounting shaft 11 after it is installed on the mounting shaft 11, that is, to provide power to the wheel 10 so that the wheel 10 rotates automatically, in this embodiment, a transmission structure 1010 is provided on the second side mounting component 101. The power component drives the wheel 10 to rotate through the power structure, so that the wheel 10 can rotate relative to the mounting shaft 11.

[0055] In some embodiments, the second side mount 101 is provided with transmission teeth near the mounting position 103, and the power component drives the entire wheel 10 to rotate through gear transmission; in other embodiments, the second side mount 101 is provided with a plane near the mounting position 103, and the power component drives the entire wheel 10 to rotate through rollers that cooperate with the plane. Other transmission structures 1010 are also not excluded.

[0056] Please refer to the attached document. Figure 4 In a further embodiment, the mounting positions 103 are evenly distributed radially on the wall of the roller body 102. The mounting position 103 includes a groove 1030 and a through hole 1031. The groove 1030 is arranged radially, and the through hole 1031 is located at the bottom of the groove 1030.

[0057] In this embodiment, the roller body 102 is configured as a tubular structure, and the mounting positions 103 are evenly distributed along the periphery of the tubular structure on the tube wall. The number of mounting positions 103 is determined according to production efficiency requirements. Each mounting position 103 includes a groove 1030 and a perforation 1031. The grooves 1030 are evenly distributed along the circumference of the tubular structure's tube wall, and the perforations 1031 are provided at the bottom of the grooves 1030. The perforations 1031 ensure that the spraying element 12 can spray the electroplating solution onto the product for electroplating. In this embodiment, the grooves 1030 are used to cooperate with the fixture 13 for installation.

[0058] Please refer to the attached document. Figure 9In a further embodiment, the fixture 13 is provided with a recess 130, the recess 130 is provided with an electroplating hole 131, and the fixture 13 is provided with a connecting hole at a position away from the recess 130. 132 Understandably, in order to ensure that the product can be placed on the fixture 13 for electroplating, the fixture 13 is provided with a recess 130, which allows the product to be placed on it. To ensure that the desired electroplating location can be electroplated, an electroplating hole 131 is provided at the bottom of the recess 130. The electroplating hole 131 penetrates the fixture 13. The fixture 13 is provided with a connecting hole, which allows for detachable connection and installation with the mounting position 103. In actual use, the connection is made with screws.

[0059] In actual operation, the fixtures 13 are installed onto the mounting positions 103 by screws to form multiple fixtures 13 that can hold products. The products are placed in the recesses 130 on the fixtures 13. At the same time, electroplating holes 131 are set according to the positions of the products to be electroplated. This ensures that when the spraying part 12 is in operation, electroplating will only be performed on the positions of the products to be electroplated through the electroplating holes 131, achieving efficient processing and ensuring a high yield rate.

[0060] Please refer to the attached document.

[0061] Understandably, in this embodiment, the spraying component 12 includes a main component 120 and a spraying component 121. The spraying component 12 forms a liquid storage cavity through the interior of the main component 120 and the spraying component 121. The liquid storage cavity is internally connected to the mounting shaft 11, and the mounting shaft 11 is connected to the electroplating solution for supplying the electroplating solution to the spraying component 12. The spraying component 121 is used to spray out the electroplating solution for electroplating.

[0062] Please refer to the attached document. Figure 8 In a further embodiment, the spray element 121 includes an arc plate 1210, and the arc plate 1210 is evenly distributed with spray holes 122; Side plates 1211 are provided on both sides of the arc plate 1210.

[0063] Understandably, in order to better achieve electroplating of products on tubular structural components, the embodiment sets the spray nozzle 121 as an arc-shaped structure to match the inner wall shape of the tubular structural component. This allows the electroplating liquid sprayed from the arc-shaped spray nozzle 121 to be sprayed onto the product on the wheel body 10, resulting in higher electroplating efficiency.

[0064] In a further embodiment, a fastener (not shown in the figure) is provided on the mounting shaft 11.

Specifically, the fixing member (not shown in the figure) is sleeved on the shaft surface of the mounting shaft 11 and connected by an interference fit. Then, the fixing member (not shown in the figure) can be connected to the electroplating equipment by a thread.

[0066] In a specific embodiment, the fixed component is divided into a kit and a connecting ring. The connecting ring is located at one end of the kit. The kit is fitted onto the shaft surface of the mounting shaft 11 to achieve an interference fit. The connecting ring is then connected to the electroplating equipment by bolts.
