Description

Technical Field

[0001] This utility model relates to the field of vacuum electroplating tank technology, specifically a vacuum electroplating tank for an automated electroplating production line. Background Technology

[0002] Electroplating equipment is a key component in surface treatment processes. Its core component, the plating tank, holds the plating solution and provides the necessary environment for the electroplating reaction. Traditionally, plating tanks are arranged in two ways: one is a linear arrangement based on the manual operation process flow, and the other is a dispersed arrangement based on available space and plating requirements. In automated production lines, plating tanks are typically arranged sequentially according to the process flow to improve production efficiency. Vacuum plating tanks, as a common type of electroplating tank, are widely used in high-precision electroplating processes because the vacuum environment reduces oxidation and impurity interference.

[0003] A search revealed a vacuum electroplating tank for use in an electroplating production line, with publication number CN217203024U. This application uses a motor to rotate a transmission rod, and the frame moves up and down under the drive of a lead screw sleeve, making it easy to pick up and place, convenient to use, and highly automated.

[0004] However, in this method, the workpiece remains stationary in the plating tank throughout the electroplating process, lacking a dynamic turning or stirring mechanism. This results in uneven contact between the plating solution and the workpiece surface, especially for workpieces with complex shapes or internal cavities, easily creating plating dead zones and reducing the uniformity and adhesion of the plating layer. Furthermore, static electroplating is inefficient and cannot meet the demands of modern high-precision and high-efficiency production. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum electroplating tank for an automated electroplating production line to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vacuum electroplating tank for an automated electroplating production line, comprising a vacuum electroplating tank, wherein a tank cover is installed on the top of the vacuum electroplating tank, and an agitation component and a driving component are provided inside and at the bottom of the vacuum electroplating tank;

[0007] The agitation component includes:

[0008] Mounting bracket, used to stabilize the motor;

[0009] An electric motor is used to drive the synchronous movement of various components.

[0010] Gear 1 is used to drive the rack and gear 2 to reciprocate.

[0011] Preferably, the mounting bracket is fixed to the bottom of the vacuum electroplating tank. A motor is fixed to the outer surface of the mounting bracket. A gear one is fixed through and fixed to the output shaft surface of the motor. The gear one is rotatably connected to the bottom of the vacuum electroplating tank. A gear two is rotatably connected to the bottom of the vacuum electroplating tank. A rack is slidably connected to the bottom of the vacuum electroplating tank. A rotating rod is provided on the surface of the gear two. The rotating rod passes through the gear two and the vacuum electroplating tank, and is fixedly connected to the gear two. The rotating rod is rotatably connected to the vacuum electroplating tank. A stirring plate is fixed to the top of the rotating rod. The bottom of the stirring plate is in contact with the bottom of the vacuum electroplating tank. The gear two meshes with the rack. When the motor is started, it drives the gear one to rotate. When the gear one meshes with the rack, the rack moves and drives the gear two to rotate forward. When the gear one disengages from the rack, the gear one meshes with the gear two, driving it to rotate in reverse. This allows the workpiece to be rotated back and forth.

[0012] Preferably, the driving assembly includes a fixed rod fixed to the agitator plate. A groove is formed on the outer surface of the fixed rod, and a sliding rod is slidably connected to the inner wall of the groove. A spring is fixed to the outer surface of the sliding rod, with the end of the spring away from the sliding rod fixed to the inner wall of the groove. A short rod is fixed to the end of the sliding rod away from the spring, and a driving plate is fixed to the end of the short rod away from the sliding rod. A groove is formed at the bottom of the driving plate, and an abutment block is fixed to the inner wall of the vacuum plating tank. When the agitator plate reciprocates, the fixed rod, sliding rod, and driving plate reciprocate. When the inclined surface of the driving plate contacts the abutment block, the driving plate moves towards the center of the vacuum plating tank, causing the workpiece subjected to centrifugal force to retract inward. When the driving plate disengages from the abutment block, the spring releases, pushing the sliding rod, fixed rod, and driving plate back to their original positions, re-adhering to the inner wall of the vacuum plating tank. Thus, the driving plate achieves a reciprocating inward retraction movement.

[0013] Preferably, the outer surface of the vacuum electroplating tank is equipped with a drain port, and the outer surface of the drain port is equipped with a gate valve to facilitate the discharge of electrolyte.

[0014] Preferably, the surface of the first gear is fixed with four teeth, and the four teeth are arranged in two groups in a circumferential array on the outer surface of the first gear. The second gear is a half gear, which facilitates the rotation of the second gear when the first gear meshes with the rack, and the rotation of the second gear when the first gear meshes with the second gear.

[0015] Preferably, the cross-section of the contact block is triangular, which allows the driving plate to move closer to the center of the vacuum electroplating tank when it contacts the surface of the driving plate.

[0016] Compared with the prior art, this utility model provides a vacuum electroplating tank for an automated electroplating production line, which has the following beneficial effects:

[0017] 1. The vacuum electroplating tank of this automated electroplating production line, through the set agitation component, when the motor is started, when gear one meshes with the rack, the rack moves and drives gear two to rotate forward; when gear one disengages from the rack, gear one meshes with gear two, which causes gear two to rotate in reverse. With the motor running continuously, gear two can drive the rotating rod and agitator plate to rotate back and forth, so that the workpiece is constantly flipped back and forth, avoiding affecting the electroplating workpiece, and avoiding the problem of workpiece accumulation caused by unidirectional flipping, thereby improving electroplating efficiency.

[0018] 2. The vacuum electroplating tank of this automated electroplating production line, through the set drive component, when the stirring plate reciprocates, the drive plate intermittently contacts the surface of the contact block. Through the spring, the drive plate can be reciprocated to retract inward, so that the workpiece affected by centrifugal force can be retracted inward, further improving the electroplating efficiency.

[0026] like Figures 1-6 As shown, this utility model provides a technical solution: a vacuum electroplating tank for an automated electroplating production line, including a vacuum electroplating tank 1, a tank cover 2 installed on the top of the vacuum electroplating tank 1, and an agitation component 4 and a driving component 5 provided inside and at the bottom of the vacuum electroplating tank 1; the agitation component 4 includes: a mounting frame 40, a motor 41, a first gear 42, a rack 43, a second gear 44, a rotating rod 45, and an agitation plate 46.

[0027] Mounting bracket 40 is fixed to the bottom of vacuum electroplating tank 1. A motor 41 is fixed to the outer surface of mounting bracket 40. A gear 42 is fixed through and attached to the output shaft of motor 41. Gear 42 is rotatably connected to the bottom of vacuum electroplating tank 1. A gear 44 is rotatably connected to the bottom of vacuum electroplating tank 1. A rack 43 is slidably connected to the bottom of vacuum electroplating tank 1. A rotating rod 45 is provided on the surface of gear 44. The rotating rod 45 passes through gear 44 and vacuum electroplating tank 1, and is fixedly connected to gear 44. The rotating rod 45 is rotatably connected to vacuum electroplating tank 1. A stirring plate 46 is fixed to the top of the rod 45, and the bottom of the stirring plate 46 is in contact with the bottom of the vacuum electroplating tank 1. Gear 2 44 meshes with rack 43. Gear 1 42 has four teeth fixed to its surface, and the four teeth are arranged in two groups in a circumferential array on the outer surface of gear 1 42. Gear 2 44 is a half gear. The motor 41 drives gear 1 42 to rotate. When gear 1 42 meshes with rack 43, rack 43 moves and drives gear 2 44 to rotate forward. When gear 1 42 disengages from rack 43, rack 43 rotates and meshes with gear 2 44, driving it to rotate in reverse. In this way, with the continuous operation of motor 41, gear 2 44 can drive the rotating rod 45 and stirring plate 46 to rotate back and forth, so that the workpiece is continuously flipped, while avoiding the problem of workpiece accumulation caused by unidirectional flipping, thereby improving electroplating efficiency.

[0028] The driving component 5 includes a fixed rod 50, which is fixed to the stirring plate 46. A groove 51 is formed on the outer surface of the fixed rod 50. A sliding rod 52 is slidably connected to the inner wall of the groove 51. A spring 53 is fixed on the outer surface of the sliding rod 52. The end of the spring 53 away from the sliding rod 52 is fixed to the inner wall of the groove 51. A short rod 54 is fixed to the end of the sliding rod 52 away from the spring 53. A driving plate 55 is fixed to the end of the short rod 54 away from the sliding rod 52. A groove 56 is formed at the bottom of the driving plate 55. An abutment block 57 is fixed to the inner wall of the vacuum electroplating tank 1. The abutment block 57 has a triangular cross-section. When the stirring plate 46 reciprocates, it synchronously drives the fixed rod 50, the sliding rod 52 and the driving plate 55 to reciprocate. When the inclined surface of the driving plate 55 contacts the abutting block 57, the driving plate 55 moves towards the center of the vacuum electroplating tank 1, causing the workpiece subjected to centrifugal force to retract inward. Simultaneously, the spring 53 is compressed, and the stirring plate 46 passes through the groove 56 to avoid interference. When the driving plate 55 disengages from the abutting block 57, the spring 53 is released, pushing the slide rod 52, the fixing rod 50, and the driving plate 55 back to their original positions, re-adhering to the inner wall of the vacuum electroplating tank 1. In this way, the driving plate 55 achieves a reciprocating inward retraction motion, effectively improving electroplating efficiency. A drain port 3 is installed on the outer surface of the vacuum electroplating tank 1, and a gate valve is installed on the outer surface of the drain port 3 to facilitate the discharge of electrolyte.

[0029] When electroplating is required, the workpiece is placed in the vacuum electroplating tank 1, and the electrolyte is also placed in the vacuum electroplating tank 1. The tank cover 2 is then closed, and electroplating can begin. Simultaneously, the motor 41 is turned on, causing gear 42 to rotate. When gear 42 meshes with rack 43, rack 43 moves, simultaneously driving gear 44 to rotate forward. When gear 42 is not meshed with rack 43, rack 43 meshes with gear 44, driving gear 44 to rotate in reverse. Thus, while the motor 41 continues to operate, gear 44 drives the rotating rod 45 and the agitator plate 46 to rotate reciprocally. This causes the agitator plate 46 to rotate the workpiece back and forth, preventing continuous rotation in one direction from causing the workpiece to be damaged. The workpieces are piled up in one place to improve electroplating efficiency. At the same time, when the stirring plate 46 reciprocates, it drives the fixed rod 50, the sliding rod 52, and the driving plate 55 to reciprocate. When the surface of the driving plate 55 contacts the inclined surface of the contact block 57, the driving plate 55 moves closer to the center of the vacuum electroplating tank 1, so that the workpiece affected by centrifugal force can be pulled inward. At this time, the spring 53 is compressed, and the stirring plate 46 passes through the groove 56 to avoid affecting the movement of the driving plate 55. When the driving plate 55 is no longer in contact with the surface of the contact block 57, the spring 53 is released, which drives the sliding rod 52, the short rod 54, and the driving plate 55 to reset and re-fit against the inner wall of the vacuum electroplating tank 1, so that the driving plate 55 can reciprocate to pull inward, thus improving electroplating efficiency.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
