Description

Technical Field

[0001] This utility model relates to the field of electrodeposition equipment technology, and in particular to a holding device for electrodeposition equipment. Background Technology

[0002] Electrodeposition equipment is a key device widely used in surface treatment. It primarily uses an electric current to reduce metal ions from an electrolyte and deposit them onto the surface of the workpiece, forming a uniform and dense metal coating. This process is commonly used for electroplating metals such as copper, nickel, and zinc, and is widely applied in industries such as electronics, automotive, and machinery manufacturing. The holding device, as one of the core components of the electrodeposition equipment, directly affects the stability of the workpiece during the electrodeposition process, the uniformity of the coating, and the overall processing efficiency due to its structural design and clamping performance. In practical applications of electrodeposition equipment, the holding device plays a crucial role. As a key link in workpiece fixation and conductivity, its clamping stability, conductivity, and ease of operation have a decisive impact on the overall effect of electrodeposition and the quality of the coating. Especially in the core process of immersing the workpiece in the electrolytic tank and conducting electrodeposition, existing holding devices have gradually revealed a series of significant limitations and technical problems when clamping workpieces of different shapes, sizes, or materials.

[0003] Specifically, existing electrodeposition equipment is not ideal for effectively securing and clamping the workpiece to be electrodeposited. For example, utility model patent CN206706234U discloses a simple electrodeposition device for copper plating, including components such as a rocker arm, crossbar, stirring shaft, anode plate, cathode plate, end cap, electrolytic cell, observation window, support column, alcohol lamp, small storage battery, and stirring blades. This device achieves stirring manually and uses an alcohol lamp to provide the temperature required for electrolysis, thereby improving deposition efficiency.

[0004] While this equipment offers advantages in energy saving and safety, its holding device has significant shortcomings: First, the lack of an adjustable clamping structure makes it difficult to quickly clamp workpieces of various sizes; second, unstable clamping can easily lead to workpiece displacement or detachment during electrodeposition, affecting coating uniformity and adhesion; third, poor conductivity at the clamping point can result in uneven current distribution, thus affecting deposition quality and production consistency. Furthermore, the cumbersome clamping operation and low workpiece change efficiency significantly reduce the overall workpiece processing speed and equipment utilization efficiency. Therefore, to address these shortcomings of existing technology, we urgently need an innovative holding device for electrodeposition equipment to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a holding device for electrodeposition equipment, which solves the problems of the lack of adjustable clamping structure in the prior art, making it difficult to adapt to the rapid clamping of workpieces of various specifications; secondly, unstable clamping can easily cause the workpiece to shift or fall off during the electrodeposition process, affecting the uniformity and adhesion of the coating.

[0006] To achieve the above objectives, this utility model provides a holding device for an electrodeposition equipment, including an electrodeposition tank, and a side frame fixedly connected to one side of the outer wall of the electrodeposition tank, and a drive motor fixedly connected to one side of the outer wall of the side frame by bolts.

[0007] A bidirectional screw is rotatably connected to the inner side of the side frame, and one end of the bidirectional screw passes through the side wall of the side frame and is connected to the output shaft of the drive motor. Nut seats are threadedly connected to both ends of the bidirectional screw. The inner sides of the electrodeposition tank are provided with bearing plates, and one side of each bearing plate is fixedly connected to one side of each nut seat. Clamping plates are elastically connected to the opposite sides of the two bearing plates. A docking frame is fixedly connected to one side of one of the two bearing plates, and an inner plate that matches the docking frame is fixedly connected to one side of the other bearing plate.

[0008] The electrodeposition tank has a spray plate fixedly connected to one side of its top, a pump body fixedly connected to one side of its outer wall by bolts, and a filter fixedly connected to one side of its side by bolts. The inlet of the filter is connected to the lower part of the electrodeposition tank through a bottom pipe, the inlet of the pump body is connected to the outlet of the filter, and the outlet of the pump body is connected to the top of the spray plate.

[0009] The electrodeposition tank has a cover plate that is hinged to the outside of the tank, and a base that is fixedly connected to the bottom of the tank.

[0010] One end of the bidirectional screw is rotatably connected to the inner wall of the side frame via a rotating shaft, and the other end of the bidirectional screw passes through the side wall of the side frame via a bearing sleeve.

[0011] Each of the two clamping plates has an anti-slip plate fixedly connected to one side of the opposite side, and one side of each clamping plate is fixedly connected to one side of each of the two bearing plates by compression springs. Furthermore, one side of each of the two bearing plates is fixedly connected to one side of each of the two clamping plates by several telescopic rods.

[0012] One side of each of the two support plates is penetrated through a movable groove into one side of the electrodeposition tank.

[0013] This utility model discloses a holding device for electrodeposition equipment. Through a linkage structure consisting of a drive motor, a bidirectional screw, and a nut seat, combined with the coordinated action of a support plate and a clamping plate, it achieves automatic clamping and releasing of the workpiece. This effectively solves the problems of existing technologies lacking adjustable clamping structures and being unable to adapt to workpieces of various specifications, greatly improving clamping flexibility and applicability. Secondly, the clamping plate is installed on the support plate using an elastic connection, providing adaptive pressure during clamping to prevent workpiece damage due to excessive clamping or workpiece displacement and fall due to insufficient clamping, thus improving clamping stability and electrodeposition consistency. Thirdly, the mating structure between the docking frame and the inner plate enhances the contact area and conductive path between the clamping components, improving the conductivity of the clamping parts and avoiding uneven current distribution caused by poor contact, thereby improving coating quality and production consistency. Furthermore, the entire holding device is compact, easy to operate, and has rapid clamping and releasing actions, significantly reducing the frequency of manual intervention and improving workpiece change efficiency and overall processing speed. In summary, this invention not only effectively overcomes the shortcomings of existing holding devices in terms of poor clamping adaptability, poor conductivity, and cumbersome operation, but also provides a more stable, efficient, and safe workpiece fixing solution for electrodeposition equipment, meeting the needs of modern electrodeposition processes for high precision, multi-variety, and mass production, and has good application prospects and promotion value.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 .

[0023] A holding device for an electrodeposition apparatus includes an electrodeposition chamber 1, and a side frame 9 is fixedly connected to one side of the outer wall of the electrodeposition chamber 1, and a drive motor 12 is fixedly connected to one side of the outer wall of the side frame 9 by bolts.

[0024] A bidirectional screw 10 is rotatably connected to the inner side of the side frame 9, and one end of the bidirectional screw 10 passes through the side wall of the side frame 9 and is connected to the output shaft of the drive motor 12. Nut seats 11 are threadedly connected to both ends of the bidirectional screw 10. Both sides of the inner side of the electrodeposition tank 1 are provided with bearing plates 7, and one side of each of the two bearing plates 7 is fixedly connected to one side of each of the two nut seats 11. Clamping plates 13 are elastically connected to the opposite sides of the two bearing plates 7. A docking frame 18 is fixedly connected to one side of one of the two bearing plates 7, and an inner plate 17 that is used in conjunction with the docking frame 18 is fixedly connected to one side of the other bearing plate 7.

[0025] First, the workpiece to be electrodeposited is placed between two clamping plates 13, and the drive motor 12 is started. The output shaft of the drive motor 12 drives the bidirectional screw 10 inside the side frame 9 to rotate. Since the two ends of the bidirectional screw 10 have opposite thread structures, the two nut seats 11 installed on it will move towards the middle or sides respectively under the action of the threads, thereby driving the two support plates 7 fixedly connected to it to move closer or further away synchronously. When the two support plates 7 approach each other, the clamping plates 13 on them will elastically compress and tightly fit against the surface of the workpiece, achieving stable clamping of the workpiece; at the same time, the mating frame 18 fixedly installed on one of the support plates 7 forms a mating connection with the inner plate 17 on the other support plate 7, further enhancing the contact stability and conductivity of the clamping structure. In this process, the clamping plates 13 are installed on the support plates 7 in an elastic connection manner, so that the clamping force has a certain buffering capacity, which can adapt to workpieces of different thicknesses, shapes and materials, and avoid workpiece deformation or damage caused by rigid clamping. Furthermore, the surface of the clamping plate 13 can be designed with a conductive material or embedded with conductive contacts to ensure that current is stably conducted from the power source to the workpiece surface through the clamping plate 13, thereby achieving a uniform current distribution and ensuring the quality of electrodeposition. The entire clamping process is highly automated and easy to operate. The workpiece can be quickly clamped and released simply by controlling the drive motor 12, significantly improving processing efficiency and operational safety.

[0026] Furthermore, a spray plate 3 is fixedly connected to one side of the top of the electrodeposition tank 1, and a pump body 4 is fixedly connected to one side of the outer wall of the electrodeposition tank 1 by bolts. A filter 5 is also fixedly connected to one side of the electrodeposition tank 1 by bolts. The inlet of the filter 5 is connected to the lower part of the electrodeposition tank 1 through a bottom pipe 6, the inlet of the pump body 4 is connected to the outlet of the filter 5, and the outlet of the pump body 4 is connected to the top of the spray plate 3. During the electrodeposition process, the electrolyte can flow from the bottom of the electrodeposition tank 1 into the filter 5 through the bottom pipe 6 for impurity filtration. Then, it is pressurized by the pump body 4 and transported to the top spray plate 3, and evenly sprayed back into the interior of the electrodeposition tank 1. This achieves the effect of improving the electrolyte circulation efficiency and ensuring the clean and stable operation of the electrodeposition process.

[0027] Furthermore, a cover plate 2 is rotatably connected to the outer side of the electrodeposition tank 1 via a hinge, and a base 8 is fixedly connected to the bottom of the electrodeposition tank 1. This allows the cover plate 2 to be easily closed and the electrodeposition tank 1 sealed after the workpiece clamping or maintenance operation is completed, preventing electrolyte from splashing out or external impurities from entering. This achieves the effects of improving equipment safety, facilitating maintenance, and maintaining a clean working environment.

[0028] Furthermore, one end of the bidirectional screw 10 is rotatably connected to the inner wall of the side frame 9 via a rotating shaft, and the other end of the bidirectional screw 10 passes through the side wall of the side frame 9 via a bearing sleeve. When the drive motor 12 drives it to rotate, this double-end support method effectively improves the stability and transmission accuracy of the bidirectional screw 10, thereby extending the service life of the device and reducing vibration errors.

[0029] Furthermore, anti-slip plates 16 are fixedly connected to opposite sides of both clamping plates 13, and one side of each clamping plate 13 is fixedly connected to one side of each of the two bearing plates 7 via compression springs 14. One side of each of the two bearing plates 7 is fixedly connected to one side of each of the two clamping plates 13 via several telescopic rods 15. During the clamping process, the compression springs 14 provide buffering force to accommodate workpieces of different sizes, the telescopic rods 15 ensure that the clamping plates 13 move smoothly, and the anti-slip plates 16 enhance the clamping friction, thereby improving clamping stability, preventing workpiece slippage and displacement, and avoiding damage to the workpiece surface.

[0030] Furthermore, one side of each of the two support plates 7 passes through one side of the electrodeposition box 1 via a movable groove 19. The two support plates 7 can slide back and forth along the outside of the electrodeposition box 1 within the movable groove 19, thereby enabling the clamping components to move flexibly inside and outside the box. This not only facilitates the rapid loading and unloading of workpieces but also improves the overall space utilization and operational convenience of the device, achieving the effect of optimizing the structural layout and improving work efficiency.

[0031] In summary:

[0032] First, the workpiece to be processed is placed inside the electrodeposition chamber 1, between two clamping plates 13. Then, the drive motor 12 is started, and its output shaft drives the bidirectional screw 10, which is rotatably connected inside the side frame 9, to rotate. One end of the bidirectional screw 10 passes through the side wall of the side frame 9 via a bearing sleeve and is connected to the drive motor 12 for transmission. The other end is rotatably connected to the inner wall of the side frame 9 via a rotating shaft, forming a double-end support structure, thereby ensuring smooth operation and high transmission accuracy of the bidirectional screw 10. Because the two ends of the bidirectional screw 10 have oppositely oriented threads, the two nut seats 11 installed on it will move towards the center or sides respectively under the action of the threads, thereby causing the two bearing plates 7 fixedly connected to them to move closer or further away synchronously. When the two bearing plates 7 approach each other, the clamping plates 13 elastically connected on their opposite sides begin to contact and press against the workpiece surface. The clamping plate 13 is connected to the support plate 7 via a compression spring 14 and a telescopic rod 15. The compression spring 14 provides buffering force to accommodate workpieces of different thicknesses and shapes, preventing damage to the workpieces due to rigid clamping. The telescopic rod 15 ensures that the clamping plate 13 moves stably in a straight line, preventing deviation and swaying that could affect the clamping effect. Simultaneously, an anti-slip plate 16 is fixed to the opposite side of the clamping plate 13, effectively enhancing clamping friction and preventing the workpiece from sliding or falling off during electrodeposition, thus improving clamping stability. After clamping, the mating frame 18 fixed on one support plate 7 engages with the inner plate 17 on the other support plate 7, further enhancing the conductive contact area between the clamping components. This allows current to be conducted more evenly from the power source through the clamping plate 13 to the workpiece surface, thereby improving coating quality and production consistency. Furthermore, one side of each support plate 7 extends through a movable groove 19 to one side of the electrodeposition tank 1, allowing the entire clamping assembly to slide flexibly back and forth within the movable groove 19 along the outside of the electrodeposition tank 1. This facilitates quick workpiece loading and unloading and optimizes space layout, improving overall operating efficiency and equipment applicability. Throughout the electrodeposition process, to ensure clean and stable electrolyte circulation, pump 4 is activated, transporting the electrolyte from the bottom of electrodeposition tank 1 through bottom pipe 6 to filter 5 for impurity filtration. Afterward, it is pressurized and fed into spray plate 3, then evenly sprayed back into the electrodeposition tank 1 from the top of spray plate 3, achieving efficient electrolyte circulation and purification and maintaining a good electrodeposition environment. Simultaneously, a cover plate 2 is hinged to one side of the electrodeposition tank 1. After clamping or maintenance operations, the cover plate 2 can be used to seal the electrodeposition tank 1, preventing electrolyte splashing or external impurities from entering, thus improving equipment safety and the cleanliness of the operating environment. The base 8, fixedly connected to the bottom of the electrodeposition tank 1, provides a stable support foundation for the entire device, ensuring structural stability during operation.The linkage mechanism consisting of drive motor 12, bidirectional screw 10, and nut seat 11, combined with the coordinated action of bearing plate 7 and clamping plate 13, achieves automatic clamping and release of workpieces. This solves the problems of non-adjustable clamping structures and difficulty in adapting to multiple workpiece specifications in existing technologies, significantly improving clamping flexibility and applicability. Clamping plate 13 is installed on bearing plate 7 using an elastic connection, enhancing its self-adaptability during clamping, preventing workpiece deformation or displacement, and improving clamping stability and electrodeposition consistency. The mating structure between docking frame 18 and inner plate 17 enhances the stability of the conductive path, improves the conductivity of the clamping area, ensures uniform current distribution, and improves plating performance. The electrolyte circulation system, consisting of components such as the spray plate 3, pump body 4, filter 5, and bottom pipe 6, effectively improves the flow efficiency and cleanliness of the electrolyte, ensuring the continuous and stable operation of the electrodeposition process. The hinged structure of the cover plate 2 facilitates opening and closing, improving the operational safety and maintenance convenience of the equipment. The double-end support structure of the bidirectional screw 10 enhances transmission stability and extends the service life of the device. The combination of the anti-slip plate 16, the compression spring 14, and the telescopic rod 15 effectively improves the clamping friction and clamping reliability, preventing workpiece slippage. The design of the movable groove 19 allows the clamping components to move flexibly inside and outside the box, optimizing space utilization and improving operational convenience. Therefore, this utility model not only effectively overcomes the shortcomings of existing holding devices in terms of poor clamping adaptability, poor conductivity, and cumbersome operation, but also provides a more efficient, stable, and safe workpiece clamping solution for electrodeposition equipment, meeting the needs of modern electrodeposition processes for high precision, multi-variety, and mass production, and has broad application prospects and promotional value.

[0033] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
