Description

Technical Field

[0001] The invention belongs to the technical field of electroplating devices, and specifically refers to a self-adaptive immersion electroplating device. Background Art

[0002] Electroplating refers to the process of immersing the workpiece in the electroplating solution and then applying electricity, which eventually causes metal ions to deposit on the surface of the workpiece to form a coating. For workpieces with a single geometric shape (such as a cube, cylinder, etc.), the larger the size of the workpiece, the heavier the mass, and the larger the surface area, the longer the electroplating time will take. For some workpieces with similar specifications, many factories do not adjust the specific electroplating time for each workpiece in order to simplify the production steps. This is because it is quite cumbersome to adapt separate technical parameters to each workpiece with similar sizes. Many mixed production lines require frequent shutdowns to switch parameters.

[0003] However, if it is not adapted in this way, the surface coating thickness of the workpiece will be inconsistent. If the difference is small, it will affect the consistency of the product and cannot be used in high-end industries with high precision and high requirements. If the difference is large, both too small and too large coating thickness will lead to reduced durability of the coating. If the electroplating layer is too thin, the protective ability will be insufficient. If the electroplating layer is too thick, it is prone to quality defects such as cracks and peeling.

[0004] Therefore, if a technical solution can be proposed that can automatically adjust the electroplating time according to the condition of the workpiece, it will be able to greatly improve product quality while ensuring production efficiency. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes an adaptive immersion electroplating equipment based on weight sensing that can automatically adjust the electroplating duration; compared with the traditional, constant electroplating time, this solution can actively adjust and compensate the electroplating duration according to the weight change of the workpiece, thereby greatly reducing the thickness fluctuation caused by the change of the workpiece surface area.

[0006] In order to continuously maintain the matching of movement speeds among various mechanisms during the change of electroplating duration, the present invention proposes a driving scheme based on a motor. Through mechanical linkage, while the driving motor is continuously and stably rotating, the driving force of the driving motor is utilized to simultaneously drive the "lifting and lowering movement mechanism", "rotating and toggling mechanism" and "loading and unloading conveying mechanism", which not only simplifies the structure, but also achieves the matching of movement speeds among various structures without any electronic feedback and control module.

[0007] Moreover, the present invention also creatively proposes an intermittent reciprocating lifting mechanism and a gravity-sensing speed regulating mechanism, which senses the deadweight of the workpiece through a gravity-sensing component and adjusts the rotational resistance of the outer gear ring based on this, thereby achieving the technical effect of real-time and dynamic adjustment of the output speed of the output shaft frame.

The rotating lever 48 has a tendency to extend outward in a natural state, but may retract when blocked by the conveyor belt 58 or the pressure-sensitive stage 13.

[0063] When in use, the user first needs to start the drive motor 28, and the drive motor 28 rotates the output shaft frame 30 through the central gear 29. Since the outer ring gear 32 can rotate in the ring gear support frame 34, when the rotation speed of the drive motor 28 is constant, the greater the rotation resistance of the outer ring gear 32, the greater the rotation speed of the output shaft frame 30. When the rotation resistance of the outer ring gear 32 is reduced to nearly zero (a virtual extreme working condition), the output shaft frame 30 may even be unable to output torque; When the output shaft frame 30 rotates with the active bevel gear 33, it will continuously rotate with the bidirectional stud 17 through the driven bevel gear 19, and at the same time, it will rotate with the rotating disk 45 through the meshing transmission between the driven bevel gear 19 and the rotating bevel gear 65. When the rotating disk 45 rotates, on the one hand, it will rotate with the special-shaped dial component 42, and on the other hand, it will move with the conveying roller 57 and the conveying belt 58 through belt transmission. Since the rotating disk 45 and the conveying belt 58 are both driven by the active bevel gear 33 and the driven bevel gear 19 and the transmission ratio between the rotating disk 45 and the conveying belt 58 remains unchanged, during the change of the output speed of the active bevel gear 33, the relative movement speed between the turntable dial mechanism 3 and the loading and unloading mechanism 4 always remains matched.

[0064] During the rotation of the special-shaped rotating ring 46, the support wheel 53 rolls along the conveyor belt 58 after contacting the conveyor belt 58. At this time, the next group of workpieces has not reached the end of the conveyor belt 58, so the rotating lever 48 will not contact the next group of workpieces; after passing the pressure-sensitive worktable 13, it moves along the central slope 23 and the lifting platform 10 to the conveyor belt 58 at the other end. During this process, the rotating lever 48 will push the workpiece on the pressure-sensitive worktable 13 that has just completed electroplating to the conveyor belt 58 at the other end. After reaching the limit position, the rotating lever 48 will leave the conveyor belt 58 and rotate upward with the special-shaped rotating ring 46.

[0065] During the rotation of the special-shaped rotating ring 46, when the fixed lever 51 is about to approach the conveying belt 58, the next workpiece to be processed has been conveyed to the front of the fixed lever 51 by the conveying belt 58, so the fixed lever 51 cannot be extended. Therefore, during the rotation of the fixed lever 51, the fixed lever 51 can only move the workpiece on the conveying belt 58 to the pressure-sensitive stage 13, and then leave the workpiece; Through the above process, when the special-shaped rotating ring 46 rotates a unit angle, it can push the workpiece that has just been processed from the pressure-sensitive stage 13 to the conveyor belt 58 on the unloading side, and at the same time push the workpiece to be processed on the conveyor belt 58 on the loading side to the pressure-sensitive stage 13.

[0066] During the rotation of the special-shaped rotating ring 46, the bidirectional stud 17 is continuously rotating in one direction. However, since the bidirectional stud 17 has a bidirectional thread matching the lifting drive nut 16, the lifting drive nut 16 is actually continuously lifting and lowering. When the lifting drive nut 16 presses the lifting platform 10 to descend, the lifting platform 10 and the workpiece to be processed on the pressure-sensitive stage 13 are lowered together, and the workpiece can be electroplated after being immersed in the electroplating solution. After the lifting drive nut 16 moves to the bottom end of the two-way stud 17, it rises in the opposite direction. At this time, the lifting platform 10 rises synchronously with the lifting drive nut 16 under the elastic force of the platform return spring 11. However, when the platform return spring 11 reaches a balanced state, the lifting platform 10 stops rising. At this time, the lifting drive nut 16 continues to rise a certain distance alone under the guidance of the nut guide rod 21, and then returns to fall. Therefore, during the reciprocating lifting process of the lifting drive nut 16, the lifting platform 10 stays at the top for a period of time, and the material shifting process of the turntable type material shifting mechanism 3 occurs during this period of time.

[0067] Under the condition that other factors remain unchanged, the heavier the workpiece is, the larger the surface area of ​​the simple geometric workpiece is, and theoretically, the longer the electroplating duration is required; and the heavier the workpiece is, the greater the amount of the pressure-sensitive stage 13 sinks relative to the hoisting bottom shell 12. At this time, the gas between the hoisting bottom shell 12 and the pressure-sensitive stage 13 is squeezed to between the partition plate 36 and the piston part 40 through the conductive hose 15. As the air pressure between the partition plate 36 and the piston part 40 increases, under the dual action of the air pressure and the brake preload spring 37, the squeezing force and friction force between the brake drum 35 and the outer gear ring 32 are also smaller, thereby reducing the rotational resistance of the outer gear ring 32; When the output speed of the driving motor 28 is constant, if the rotational resistance of the outer gear ring 32 decreases, the speed of the output shaft frame 30 will also decrease accordingly, thereby achieving the technical effect of reducing the movement speed of the turntable material feeding mechanism 3 and the loading and unloading mechanism 4 and extending the duration of the workpiece being immersed in the electroplating solution.
