Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, specifically an electroplating device. Background Technology

[0002] Barrel plating is an electroplating process in which a certain number of small parts are placed in a special barrel, and various metal or alloy plating layers are deposited on the surface of the parts by means of indirect electrical conduction while the parts are rolling, so as to achieve surface protection, decoration and various functional purposes.

[0003] The commonly used rolling method involves inserting an electroplating head, connected by a flexible wire, into the drum from both ends, where it is pressed down by the workpiece being plated during the rolling process to complete the electroplating. This structure is disclosed in patents such as CN220132393U and CN220413589U, which utilize this structure to electroplat various workpieces. However, because the drum continuously rolls during electroplating, the electroplating head, due to friction within the drum, is prone to rotating with it and detaching from the workpiece, leading to uneven electroplating. Therefore, this problem urgently needs to be addressed. Utility Model Content

[0004] To avoid and overcome the technical problems existing in the prior art, this utility model provides an electroplating apparatus. This utility model can effectively improve the uniformity of electroplating.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An electroplating apparatus includes a support frame, on which a horizontally arranged connecting sleeve is fixedly mounted. Both sides of the connecting sleeve are coaxially connected to end covers, each end cover having a liquid inlet hole. The inner cavities of the two end covers are connected to each other through the connecting sleeve to form an electroplating chamber. The two end covers can rotate coaxially to agitate the electroplated parts within the electroplating chamber. An electroplating head is mounted on the inner ring surface of the connecting sleeve, and the electroplating head is located at the lowest position of the electroplating chamber.

[0007] As a further embodiment of this utility model: outer limiting rings are coaxially fixed to the outer sides of both end covers, and the connecting sleeve is sleeved on the corresponding side of the end cover opening and abuts against the outer limiting rings.

[0008] As a further improvement of this utility model: both sides of the connecting sleeve are coaxially fixed with inner limiting rings, and an inner ring groove is coaxially opened on the inner wall surface of the end cover opening. The inner limiting ring is coaxially inserted into the inner ring groove, and at this time the inner ring surface of the limiting ring and the inner wall surface of the end cover are smoothly transitioned.

[0009] As a further improvement of this utility model: both end covers are coaxially fixed with transmission gears via transmission shafts, and the transmission gears are connected to the drive gear driven by a rotary motor.

[0010] As a further embodiment of this utility model: the bracket includes support plates symmetrically arranged on both sides of the connecting sleeve, the two support plates are connected to each other by a fixing rod, and the fixing rod passes through the positioning hole opened on the connecting sleeve.

[0011] As a further improvement of this utility model: a guide hole is provided on the support plate, a bearing is coaxially fixed in the guide hole, the transmission shaft is coaxially sleeved in the bearing, and the transmission shaft is detachably connected to the end cover.

[0012] As a further improvement of this utility model, the drive shaft is inserted into a countersunk hole at the tail of the end cover and a key connection is used to achieve the detachable connection shown.

[0013] As a further improvement of this utility model: both ends of the fixing rod are threaded ends, which pass through the support plate and are threadedly connected to the nut, so that both drive shafts abut against the tail of the corresponding end cover.

[0014] As a further improvement of this utility model, a support foot is installed at the bottom of the support plate.

[0015] As a further improvement of this utility model: the end cover, connecting sleeve, support plate, transmission shaft, transmission gear, fixing rod, inner limiting ring and outer limiting ring are all made of plastic.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model constructs an electroplating chamber using a horizontally arranged connecting sleeve and a coaxially fastened end cover. The liquid inlet of the end cover facilitates the injection of electroplating solution, ensuring smooth electroplating operations. Simultaneously, the electroplating head is fixed to the inner ring surface of the connecting sleeve and positioned at the lowest point of the electroplating chamber. During the process of the end cover rotating and stirring the electroplated parts, the electroplating head remains stationary and in close contact with the parts, greatly avoiding problems such as uneven electroplating and missed plating caused by head movement. This significantly improves the uniformity and integrity of the electroplating, effectively enhancing the quality and effect of electroplating and fully meeting the stringent requirements of high-quality electroplating.

[0018] 2. The outer limiting ring fixed to the outside of the end cover abuts against the corresponding side of the connecting sleeve, achieving precise positioning and stable assembly of the end cover and the connecting sleeve. During the operation of the electroplating device, the outer limiting ring effectively restricts the axial movement between the end cover and the connecting sleeve, enhancing the stability of the overall structure of the electroplating chamber and ensuring the reliable operation of the electroplating process. Furthermore, this structural design facilitates disassembly and installation, greatly simplifying subsequent maintenance and reducing maintenance difficulty and costs.

[0019] 3. The inner limiting rings on both sides of the connecting sleeve are inserted into the inner ring grooves of the end cover's inner wall, and the inner ring surface of the limiting rings smoothly transitions with the inner wall surface of the end cover, further improving the assembly accuracy of the end cover and the connecting sleeve. The smooth transition of the inner wall surface effectively reduces the flow resistance of the electroplating solution in the electroplating chamber, allowing the electroplating solution to flow more smoothly and fully coat the electroplated parts, which helps to improve the electroplating effect; at the same time, the tight fit also enhances the sealing of the structure, prevents electroplating solution leakage, and avoids pollution to the working environment and waste of resources.

[0020] 4. The end cover is fixed to a transmission gear via a drive shaft, which is then connected to the drive gear driven by a rotary motor. This transmission method provides stable and efficient power transmission to the end cover. The rotary motor, as the power source, transmits power precisely and stably to the end cover through the meshing of the drive gear and the transmission gear, ensuring that the end cover rotates at the set speed and direction, achieving uniform stirring of the electroplated parts. This transmission structure has high transmission efficiency and stable and reliable operation, ensuring the consistency and stability of the stirring action during the electroplating process, thereby improving the electroplating quality.

[0021] 5. The bracket adopts a symmetrically arranged support plate and fixing rod structure. The support plate provides stable support for the connecting sleeve, and the fixing rod passes through the positioning holes of the connecting sleeve to firmly connect the components into a whole. The bracket structure can effectively distribute the force during the operation of the electroplating device, enhance the overall rigidity and stability of the device, and maintain structural stability during long-term operation. This reduces the impact of vibration and other factors on the electroplating effect, providing a solid foundation for the smooth operation of electroplating. Guide holes are opened on the support plate and bearings are fixed thereon. The drive shaft is sleeved in the bearing and detachably connected to the end cover, effectively reducing the frictional resistance when the drive shaft rotates, making the rotation of the end cover more flexible and smooth. At the same time, the detachable connection method facilitates the individual disassembly and replacement of components such as the end cover and drive shaft. When the equipment malfunctions or requires maintenance, the problem can be quickly located and resolved, greatly improving the maintenance efficiency of the equipment and reducing maintenance costs and downtime.

[0022] 6. The drive shaft and end cover are connected by a key for easy disassembly. Key connections are characterized by their simple structure and reliable force transmission. This ensures that the drive shaft transmits rotational power to the end cover stably and efficiently, preventing slippage during transmission. Moreover, during disassembly, the drive shaft and end cover can be easily separated simply by loosening the relevant parts, facilitating the inspection, maintenance, and replacement of individual components. This simple and quick operation improves the convenience of equipment maintenance and work efficiency.

[0023] 7. The threaded ends of the fixing rod mate with the nuts, allowing the drive shaft to abut against the tail of the end cover. This axially fixes the drive shaft and end cover, effectively preventing axial displacement during transmission and ensuring the stability and reliability of the transmission system. Simultaneously, adjusting the nuts allows for easy adjustment of the assembly clearance between the drive shaft and end cover, ensuring the transmission system is in optimal working condition and further improving the stability and efficiency of the device.

[0024] 8. The support feet installed at the bottom of the support plate enable the electroplating device to be placed stably in the electroplating tank, effectively preventing the device from shaking or tilting due to uneven ground, and ensuring the stability of the electroplating process.

[0025] 9. End caps, connecting sleeves, and other components are all made of plastic. Plastic has the advantages of being lightweight and low-cost, which can effectively reduce the overall weight of the electroplating equipment, making it easier to handle and install. At the same time, the good corrosion resistance of plastic can effectively resist the erosion of electroplating solutions, extend the service life of the equipment, reduce the maintenance and replacement costs caused by component corrosion and damage, improve the economy and practicality of the equipment, and reduce the production and operating costs of enterprises.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-5 The usage process of this utility model is as follows:

[0034] I. Installation Preparation

[0035] Check that the inside of the electroplating tank is clean, ensuring there are no impurities or oil residues to avoid affecting the performance of the electroplating solution and the quality of electroplating.

[0036] Carefully inspect all components of the electroplating apparatus, including the bracket 10, connecting sleeve 20, end cover 40, drive shaft 50, and drive gear 51, to ensure there is no damage or deformation and that all connections are secure. If any problems are found with any components, repair or replace them promptly.

[0037] Lay anti-slip rubber pads at appropriate locations at the bottom of the electroplating tank to place the electroplating equipment, further enhancing the stability of the equipment and preventing direct contact between the equipment and the electroplating tank, thus preventing wear.

[0038] II. Equipment Installation

[0039] First, store the electroplated parts in the end cover 40. Connect the end cover 40 to the connecting sleeve 20. Align the outer limiting ring 42 with the corresponding side of the connecting sleeve 20, and slowly place the connecting sleeve 20 onto the opening of the end cover 40, ensuring a tight fit between the outer limiting ring 42 and the connecting sleeve 20. Then, insert the inner limiting ring 21 into the inner ring groove 44 on the inner wall of the end cover 40. Check whether the inner ring surface of the limiting ring smoothly transitions with the inner wall surface of the end cover 40, ensuring a good seal at the connection point and preventing leakage of the electroplating solution. Alternatively, after the end cover 40 is assembled, store the electroplated parts in the end cover 40 through the openable door installed on the end cover 40.

[0040] The drive shaft 50 is passed through the guide hole 111 on the support plate 11 and the bearing, so that the drive shaft 50 is coaxially sleeved in the bearing, ensuring that the drive shaft 50 rotates flexibly. The drive shaft 50 is inserted into the countersunk hole 43 opened at the tail of the end cover 40, and the drive shaft 50 is fixed to the end cover 40 by key connection. When installing the key, it is necessary to ensure that the key and the keyway fit tightly to avoid loosening during transmission.

[0041] Then, pass the fixing rod 12 through the positioning hole 22 on the connecting sleeve 20, and turn the nut 13 to fasten the fixing rod 12 to the support plate 11. This causes the support plate 11 to drive the two drive shafts 50 to clamp the two end covers 40 and the connecting sleeve 20. During the tightening process, it is necessary to ensure that the fixing rod 12 is subjected to uniform force to prevent the connecting sleeve 20 from shifting. Use a torque wrench to tighten the nut 13 to the specified torque to ensure a secure connection.

[0042] Install transmission gears 51 on each of the two transmission shafts 50, ensuring that the transmission gears 51 are coaxially and fixedly connected to the transmission shafts 50. After installation, check whether the installation position of the transmission gears 51 is accurate and whether the rotation is smooth. Install the rotary motor in a suitable position so that the drive gear and the transmission gear 51 mesh correctly. Adjust the gear meshing clearance to ensure smooth transmission. The clearance can be adjusted by adjusting the position of the motor mounting base and the thickness of the shims.

[0043] III. Debugging Preparation

[0044] Add an appropriate amount of electroplating solution to the electroplating tank and observe its flow. Check if the inlet hole 41 is unobstructed, ensuring the electroplating solution enters the electroplating chamber 45 through the inlet hole 41. Turn on the power to the rotary motor and perform a no-load test run. Observe the rotation of the end cover 40, checking if it can rotate coaxially, if the rotation is smooth, and if there is any abnormal noise or vibration. If any abnormality is found, stop the machine and check the transmission system, including the gear meshing and the fit between the transmission shaft 50 and the bearings, and troubleshoot the problem promptly.

[0045] Use a multimeter to check if the circuit connection of the electroplating head 30 is normal, ensuring that the electroplating head 30 can work properly. Check if the connection between the electroplating head 30 and the power supply is secure, and whether there is any damage or short circuit.

[0046] IV. Electroplating Operation

[0047] Set the rotation speed and running time of the rotary motor. Adjust the stirring speed and stirring time of the end cover 40 according to the electroplating process requirements to ensure that the electroplated parts are fully stirred and improve the uniformity of electroplating. Generally, the rotation speed can be set to 50-150 rpm, and the running time is determined according to the material of the electroplated parts and the required thickness of the electroplated layer.

[0048] Start the rotary motor, and the end cover 40 begins to rotate coaxially, stirring the electroplating parts in the electroplating chamber 45. Simultaneously, turn on the electroplating power supply, and the electroplating head 30 begins the electroplating operation on the parts. During the electroplating process, closely observe the changes in the electroplating solution level, the working status of the electroplating head 30, and the electroplating condition of the parts. If any abnormalities are found, stop the machine immediately for handling.

[0049] Regularly test the composition and performance of the electroplating solution. Based on the test results, replenish or adjust the solution promptly to ensure that parameters such as concentration and pH meet process requirements. Professional electroplating solution testing equipment, such as pH meters and hydrometers, can be used for testing.

[0050] After electroplating is complete, remove the device, then open the cover and pour out the electroplated parts.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
