Description

Technical Field

[0001] The present invention belongs to the technical field of electroplating support frames, and specifically refers to an adjusting seat for an electroplating column rack. Background Art

[0002] Electroplating is a process of plating a thin layer of other metals or alloys on the surface of certain materials using the principle of electrolysis, which is a process of making the surface of metal or other material workpieces adhere to a layer of metal film by electrolysis. During operation, the workpiece generally needs to be immersed in the electroplating solution for a period of time and then taken out. However, due to the different surface areas of the workpieces, the duration of the workpiece immersed in the electroplating solution is also different.

[0003] Generally speaking, for workpieces with a single geometric shape (such as cubes, cylinders, etc.), the larger the size and weight of such parts, the larger the surface area of the workpiece. At this time, the electroplating time needs to be appropriately extended. If workpieces of different specifications are electroplated for the same time, quality defects such as too thin electroplating layer (insufficient protection ability) or too thick electroplating layer (cracks and peeling) may occur.

[0004] In order to ensure the continuity of the production process, existing electroplating production lines generally connect the feeding and discharging conveyor lines through a rotating bracket, and the workpiece is immersed in the electroplating solution and taken out by the rotation of the bracket. However, when facing workpieces of different specifications, it is necessary to manually adjust the rotation speed of the rotating bracket and the speed of the feeding and discharging conveyor lines. This conventional operation method not only requires a servo motor with a higher cost for driving, but also requires the control system to perform frequent control automatically or manually, resulting in high costs, complex structures, and difficult operations. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an adjusting support that can adaptively adjust the electroplating time according to the weight difference of workpieces of different specifications. Based on the characteristic that "for workpieces with simple shapes, the heavier the mass, the larger the surface area, and the longer the electroplating time required", this solution adaptively adjusts the transmission ratio of the adaptive speed regulation drive mechanism by sensing the mass of the workpiece, and can significantly reduce the impact of the process on the quality of the electroplating layer when the workpiece specifications change by automatically compensating the electroplating time. Moreover, the present invention also adopts an alternative feeding and discharging scheme, picking up only one magnetic carrier plate at a time, which can not only improve the overall work efficiency but also avoid the problem of disorder in the adjustment of the adaptive speed regulation drive mechanism when picking up multiple workpieces simultaneously.

[0006] The rotating rack assembly drives the loading and unloading assembly to rotate through the belt drive assembly. When the rotation speed of the rotating rack assembly changes, the loading and unloading speed of the loading and unloading assembly can also change accordingly, so as to ensure that no matter whether the rotation speed of the rotating rack assembly increases or decreases, the loading and unloading speed of the loading and unloading assembly can be kept matching it.

[0007] The technical solution adopted by the present invention is as follows: The present invention provides an adjusting seat for an electroplating column rack, which includes a rotary electroplating support mechanism, a gravity-sensing magnetic pickup mechanism, an adaptive speed regulation drive mechanism, and a loading and unloading mechanism. The rotary electroplating support mechanism includes an electroplating liquid storage tank, side support plates, and a rotating rack assembly. The side support plates are symmetrically arranged on the electroplating liquid storage tank, and the rotating rack assembly is rotatably arranged on the side support plates. The gravity-sensing magnetic pickup mechanism is symmetrically arranged on the rotating rack assembly. The adaptive speed regulation drive mechanism is arranged on the side support plates, and the loading and unloading mechanism is arranged on both sides of the rotating rack assembly.

[0008] Through the gravity-sensing magnetic pickup mechanism, the weight of the magnetic carrier plate can be sensed and the surface area of the workpiece can be reflected. Thus, when the surface area of the workpiece changes, under the condition that the rotary drive motor rotates continuously and stably, the rotation speed of the rotating rack assembly can be automatically adjusted adaptively, so as to achieve the technical purpose of automatically extending the electroplating time when the surface area of the workpiece increases and automatically shortening the electroplating time when the surface area of the workpiece decreases, and reducing the error during electroplating of different workpieces.

[0009] Preferably, the rotating rack assembly includes a rotating main shaft, a rotating bracket, and a transverse connecting rod. The rotating main shaft is rotatably arranged in the side support plate, the rotating bracket is fixedly connected to the rotating main shaft, the rotating brackets are connected and fixed by the transverse connecting rod, symmetrically arranged support crossbar parts are provided on the rotating brackets, a support chute part is provided at the end of the support crossbar part, and a hollowed-out groove part is provided on one of the rotating brackets.

[0010] Two support crossbar parts are symmetrically provided, so that the rotating brackets can alternately pick up and release the magnetic carrier plate during rotation, which not only effectively improves the efficiency, but also at the same moment, at most only one support crossbar part bears the material. Therefore, when controlling the rotation speed of the rotating rack assembly by the weight of the magnetic carrier plate, the embarrassing situation of mutual interference of the induction results of multiple heavy objects can be avoided.

[0011] Furthermore, the gravity-sensing magnetic pickup mechanism includes an elastic transverse displacement compensation component, a magnetic adsorption type hoisting component, and a gravity sensing component. The elastic transverse displacement compensation component is slidably arranged in the rotating rack assembly, the magnetic adsorption type hoisting component is rotatably arranged on the elastic transverse displacement compensation component, and the gravity sensing component is arranged on the magnetic adsorption type hoisting component.

[0012] Preferably, the elastic lateral movement compensation component includes a lateral movement slider and a lateral movement return spring. The lateral movement slider is engaged and slidably disposed in the bracket chute portion, and the lateral movement return spring is disposed between the end wall of the hollow groove portion and the lateral movement slider.

[0013] Through the lateral movement compensation of the lateral movement slider, during the loading and unloading of materials, the magnetic carrier plate can be allowed to pass, and the rotating bracket and its own lateral movement can contact or disengage from the support slide plate, so as to achieve a smooth connection between the electroplating stage and the loading and unloading stage.

[0014] As a further preference of the present invention, the magnetic suspension component includes a suspension cross bar, a suspension plate and a suspension plate return spring. The suspension cross bar is rotatably disposed in the lateral movement slider. One end of the suspension cross bar is provided with a hollow inner tube, and an induction cavity tube is provided at the central position of the suspension cross bar. The suspension cross bar is symmetrically provided with sliding sleeve portions on both sides of the induction cavity tube. Symmetrically provided with suspension guide rods on the suspension plate, the suspension plate is engaged and slidably disposed in the sliding sleeve portion through the suspension guide rods. A magnetic attraction plate is provided at the bottom of the suspension plate, and the suspension plate return spring is disposed between the suspension guide rods and the sliding sleeve portion.

[0015] The suspension cross bar and the suspension plate will maintain a vertical state, and the suspension plate will slide relative to the suspension cross bar under the gravity of the magnetic carrier plate. The sliding amplitude between the suspension plate and the suspension cross bar is determined by the weight of the magnetic carrier plate. Through the sliding amplitude of the suspension plate, the weight of the currently picked magnetic carrier plate can be feedback. In the case where the shape of the magnetic carrier plate is simple and unified, the quality and surface area of the workpiece loaded on the magnetic carrier plate can be reflected.

[0016] As a further preference of the present invention, the gravity sensing component includes a piston portion, a sliding rod portion and a first hydraulic pipeline. The piston portion is engaged and slidably disposed in the induction cavity tube. One end of the sliding rod portion is fixedly connected to the piston portion, and the other end of the sliding rod portion is fixedly connected to the suspension plate. The first hydraulic pipeline and the hollow inner tube are connected through the first hydraulic pipeline.

[0017] When the suspension plate slides relative to the suspension cross bar, it can simultaneously control the sliding of the piston portion in the induction cavity tube, and then change the transmission ratio of the adaptive speed regulation drive mechanism through the hydraulic induction and drive method, so as to achieve the technical purpose of adaptively adjusting the rotation speed of the rotating frame assembly under the condition that the rotation speed of the rotating drive motor remains unchanged.

[0018] Furthermore, the adaptive speed regulation drive mechanism includes a drive component, a driven variable diameter component and a driving variable diameter component. The drive component is disposed on the side support plate, the driven variable diameter component is disposed on the drive component, and the driving variable diameter component is disposed on the rotating frame assembly.

[0019] Preferably, the driving assembly includes a motor bracket and a rotary driving motor. The motor bracket is fixedly connected to the side support plate. The rotary driving motor is disposed on the motor bracket. A driving main shaft is provided on the rotary driving motor, and a spring baffle is provided on the driving main shaft.

[0020] As a further preference of the present invention, the driven variable-diameter assembly includes a first variable-diameter wheel, a second variable-diameter wheel, a variable-diameter wheel pre-tightening spring, and a trapezoidal transmission belt. The first variable-diameter wheel is fixedly connected to the driving main shaft. The second variable-diameter wheel is slidably disposed on the driving main shaft. The second variable-diameter wheel can axially slide relative to the driving main shaft, and the second variable-diameter wheel cannot rotate relative to the driving main shaft. The variable-diameter wheel pre-tightening spring is disposed between the second variable-diameter wheel and the spring baffle. The trapezoidal transmission belt is rolled between the first variable-diameter wheel and the second variable-diameter wheel.

[0021] By controlling the distance between the first variable-diameter wheel and the second variable-diameter wheel, the equivalent diameter at this position can be changed. Under the elastic force of the variable-diameter wheel pre-tightening spring, the equivalent diameter of the driven variable-diameter assembly always has an increasing trend. And under the linkage effect of the trapezoidal transmission belt, the equivalent diameter of the driving variable-diameter assembly always has a decreasing trend. Therefore, when the slope slider and the telescopic slope rod are not in contact, the distance between the third variable-diameter wheel and the fourth variable-diameter wheel is the largest.

[0022] As a further preference of the present invention, the driving variable-diameter assembly includes a third variable-diameter wheel, a fourth variable-diameter wheel, a telescopic cavity, a telescopic slope rod, and a second hydraulic pipeline. The third variable-diameter wheel is slidably disposed on the rotary main shaft. The third variable-diameter wheel can axially slide relative to the rotary main shaft, and the third variable-diameter wheel cannot rotate relative to the rotary main shaft. The fourth variable-diameter wheel is fixedly connected to the rotary main shaft. The trapezoidal transmission belt is rolled between the third variable-diameter wheel and the fourth variable-diameter wheel. The telescopic cavity is fixedly connected to the hollow groove portion. The telescopic slope rod is engaged and slidably disposed in the telescopic cavity. Symmetric slope sliders are provided on the third variable-diameter wheel and are slidably disposed in the hollow groove portion. The telescopic cavity and the hollow inner tube are connected through the second hydraulic pipeline.

[0023] The two variable-diameter wheel sets are driven by a trapezoidal transmission belt. Therefore, when the distance between the third variable-diameter wheel and the fourth variable-diameter wheel decreases, the distance between the first variable-diameter wheel and the second variable-diameter wheel will necessarily increase; when the distance between the third variable-diameter wheel and the fourth variable-diameter wheel increases, the distance between the first variable-diameter wheel and the second variable-diameter wheel will also decrease under the elastic force of the variable-diameter wheel pre-tightening spring. Therefore, by adjusting the distance between the third variable-diameter wheel and the fourth variable-diameter wheel, the adaptive adjustment of the transmission ratio of the adaptive speed regulation driving mechanism can be realized.

[0024] Further, the loading and unloading mechanism includes a belt drive assembly and a loading and unloading assembly. The loading and unloading assembly is arranged on the electroplating liquid storage tank. The belt drive assembly includes a driving synchronous pulley, a driven wheel shaft and a synchronous belt. The driving synchronous pulley is fixedly connected to the rotating main shaft. The driven wheel shaft is rotatably arranged in the side support plate. The driven wheel shaft and the driving synchronous pulley are connected by the synchronous belt for transmission.

[0025] Through the transmission of the belt drive assembly, on the one hand, it can make the movement directions of the two support slide plates adapt to the rotation direction of the rotating frame assembly. On the other hand, it can also keep the movement speeds of the two support slide plates match the rotation speed of the rotating frame assembly. Thus, when the rotation speed of the rotating main shaft changes, the loading and unloading speed of the loading and unloading toothed belt can still be adapted to it.

[0026] Preferably, the loading and unloading assembly includes a support slide plate, a loading and unloading toothed belt and a magnetic carrier plate. The support slide plate is fixedly connected to the electroplating liquid storage tank. The loading and unloading toothed belt is rotatably arranged on the driven wheel shaft. Trapezoidal ends are provided at both ends of the magnetic carrier plate. Meshing tooth parts matching the loading and unloading toothed belt are provided at the tops of the trapezoidal ends. The magnetic carrier plate is slidably arranged on the support slide plate.

[0027] The beneficial effects achieved by the present invention with the above structure are as follows:

[0028] (1) The gravity-sensing magnetic pickup mechanism can sense the weight of the magnetic carrier plate and reflect the surface area of the workpiece. Thus, when the surface area of the workpiece changes, under the condition that the rotation drive motor rotates continuously and stably, the rotation speed of the rotating frame assembly can be automatically adjusted adaptively. Thereby, the technical purpose of automatically extending the electroplating time when the surface area of the workpiece increases and automatically shortening the electroplating time when the surface area of the workpiece decreases is realized, and the error during electroplating of different workpieces is reduced.

[0029] (2) Two support crossbar parts are symmetrically provided, so that the rotating support can alternately pick up and release the magnetic carrier plate during rotation. It not only effectively improves the efficiency, but also at the same moment, at most only one support crossbar part bears the material. Therefore, when controlling the rotation speed of the rotating frame assembly through the weight of the magnetic carrier plate, the embarrassing situation of interference between the induction results of multiple heavy objects can be avoided.

[0030] (3) Through the cross-movement compensation of the cross-movement slider, when loading and unloading materials, the magnetic carrier plate can be allowed to pass through, and the rotating support and its own cross-movement can contact or disengage from the support slide plate, so as to realize a smooth connection between the electroplating stage and the loading and unloading stage.

[0031] (4) The hoisting crossbar and the hoisting plate will remain vertical, and the hoisting plate will slide relative to the hoisting crossbar under the gravity of the magnetic load plate. The sliding amplitude between the hoisting plate and the hoisting crossbar is determined by the weight of the magnetic load plate. Through the sliding amplitude of the hoisting plate, the weight of the currently picked magnetic load plate can be feedback. When the shape of the magnetic load plate is simple and unified, the mass and surface area of the workpiece loaded on the magnetic load plate can be reflected.

[0032] (5) When the hoisting plate slides relative to the hoisting crossbar, it can simultaneously control the sliding of the piston part in the induction cavity tube, and then change the transmission ratio of the adaptive speed regulation drive mechanism through the hydraulic induction and drive method, so as to achieve the technical purpose of adaptively adjusting the rotation speed of the rotating frame assembly under the condition that the rotation speed of the rotating drive motor remains unchanged.

[0033] (6) By controlling the distance between the first variable diameter wheel and the second variable diameter wheel, the equivalent diameter at this position can be changed. Under the elastic force of the variable diameter wheel preloading spring, the equivalent diameter of the driven variable diameter assembly always has an increasing trend, and under the linkage action of the trapezoidal drive belt, the equivalent diameter of the driving variable diameter assembly always has a decreasing trend. Therefore, when the ramp slider and the telescopic ramp rod are not in contact, the distance between the third variable diameter wheel and the fourth variable diameter wheel is the largest.

[0034] (7) The two groups of variable diameter wheel sets are driven by a trapezoidal drive belt. Therefore, when the distance between the third variable diameter wheel and the fourth variable diameter wheel decreases, the distance between the first variable diameter wheel and the second variable diameter wheel will necessarily increase; when the distance between the third variable diameter wheel and the fourth variable diameter wheel increases, the distance between the first variable diameter wheel and the second variable diameter wheel will also decrease under the elastic force of the variable diameter wheel preloading spring; therefore, by adjusting the distance between the third variable diameter wheel and the fourth variable diameter wheel, the adaptive adjustment of the transmission ratio of the adaptive speed regulation drive mechanism can be realized.

[0035] (8) Through the transmission of the belt drive assembly, on the one hand, it can make the movement directions of the two groups of support slide plates adapt to the rotation direction of the rotating frame assembly, and on the other hand, it can also keep the movement speeds of the two groups of support slide plates matching the rotation speed of the rotating frame assembly, so that when the rotation speed of the rotating main shaft changes, the loading and unloading speed of the loading and unloading toothed belt can still be adapted.

[0049] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation to the present invention. Detailed implementation manners

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0051] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0052] Such as Figures 1 to 12As shown, the present invention proposes an adjustment seat for an electroplating column rack, comprising a rotary electroplating bracket mechanism 1, a gravity-sensing magnetic pickup mechanism 2, an adaptive speed regulation drive mechanism 3 and a loading and unloading mechanism 4, the rotary electroplating bracket mechanism 1 comprises an electroplating liquid storage tank 5, a side support plate 6 and a rotating rack assembly 7, the side support plate 6 is symmetrically arranged on the electroplating liquid storage tank 5, the rotating rack assembly 7 is rotatably arranged on the side support plate 6, the gravity-sensing magnetic pickup mechanism 2 is symmetrically arranged on the rotating rack assembly 7, the adaptive speed regulation drive mechanism 3 is arranged on the side support plate 6, and the loading and unloading mechanism 4 is arranged on both sides of the rotating rack assembly 7.

[0053] The gravity-sensing magnetic pickup mechanism 2 can sense the weight of the magnetic carrier plate 54 and reflect the surface area of ​​the workpiece. When the surface area of ​​the workpiece changes, the rotation speed of the rotating frame assembly 7 is automatically adaptively adjusted while the rotating drive motor 34 continues to rotate stably, thereby achieving the technical purpose of automatically extending the electroplating time when the surface area of ​​the workpiece increases and automatically shortening the electroplating time when the surface area of ​​the workpiece decreases, thereby reducing the error in electroplating different workpieces.

[0054] The rotating frame assembly 7 includes a rotating main shaft 8, a rotating bracket 9 and a transverse connecting rod 10. The rotating main shaft 8 is rotatably arranged in the side support plate 6. The rotating bracket 9 is fixed to the rotating main shaft 8. The rotating brackets 9 are connected and fixed by the transverse connecting rod 10. The rotating brackets 9 are symmetrically provided with bracket cross bars 11. The ends of the bracket cross bars 11 are provided with bracket sliding grooves 12. One of the rotating brackets 9 is provided with a hollow groove 13.

[0055] Two bracket cross bars 11 are symmetrically provided, so that the rotating bracket 9 can alternately pick up and release the magnetic carrier plate 54 during the rotation process, which not only effectively improves the efficiency, but also at the same time, at most only one bracket cross bar 11 will carry materials. Therefore, when the rotation speed of the rotating frame assembly 7 is controlled by the weight of the magnetic carrier plate 54, the embarrassing situation that the sensing results of multiple heavy objects interfere with each other can be avoided.

[0056] The loading and unloading mechanism 4 includes a belt transmission assembly 47 and an loading and unloading assembly 48. The loading and unloading assembly 48 is arranged on the electroplating liquid storage tank 5; the belt transmission assembly 47 includes an active synchronous wheel 49, a driven wheel shaft 50 and a synchronous belt 51. The active synchronous wheel 49 is fixedly connected to the rotating main shaft 8, and the driven wheel shaft 50 is rotatably arranged in the side support plate 6. The driven wheel shaft 50 and the active synchronous wheel 49 are connected through a synchronous belt 51.

[0057] Through the transmission of the belt drive assembly 47, on the one hand, it can make the movement directions of the two groups of support slide plates 52 adapt to the rotation direction of the rotary frame assembly 7, and on the other hand, it can also keep the movement speeds of the two groups of support slide plates 52 matching the rotation speed of the rotary frame assembly 7. Thus, when the rotation speed of the rotary main shaft 8 changes, the loading and unloading speed of the loading and unloading toothed belt 53 can still be adapted to it.

[0058] The loading and unloading assembly 48 includes support slide plates 52, a loading and unloading toothed belt 53, and a magnetic load-carrying plate 54. The support slide plates 52 are fixedly connected to the electroplating liquid storage tank 5. The loading and unloading toothed belt 53 is rotatably arranged on the driven wheel shaft 50. Trapezoidal end heads 55 are provided at both ends of the magnetic load-carrying plate 54. Meshing tooth parts 56 matching the loading and unloading toothed belt 53 are provided at the tops of the trapezoidal end heads 55. The magnetic load-carrying plate 54 is slidably arranged on the support slide plates 52.

[0059] The adaptive speed regulation drive mechanism 3 includes a drive assembly 30, a driven variable diameter assembly 31, and a driving variable diameter assembly 32. The drive assembly 30 is arranged on the side support plate 6. The driven variable diameter assembly 31 is arranged on the drive assembly 30. The driving variable diameter assembly 32 is arranged on the rotary frame assembly 7.

[0060] The drive assembly 30 includes a motor bracket 33 and a rotary drive motor 34. The motor bracket 33 is fixedly connected to the side support plate 6. The rotary drive motor 34 is arranged on the motor bracket 33. A drive main shaft 44 is provided on the rotary drive motor 34. A spring baffle 45 is provided on the drive main shaft 44.

[0061] The driven variable diameter assembly 31 includes a first variable diameter wheel 35, a second variable diameter wheel 36, a variable diameter wheel pre-tightening spring 37, and a trapezoidal drive belt 38. The first variable diameter wheel 35 is fixedly connected to the drive main shaft 44. The second variable diameter wheel 36 is slidably arranged on the drive main shaft 44. The second variable diameter wheel 36 can axially slide relative to the drive main shaft 44, and the second variable diameter wheel 36 cannot rotate relative to the drive main shaft 44. The variable diameter wheel pre-tightening spring 37 is arranged between the second variable diameter wheel 36 and the spring baffle 45. The trapezoidal drive belt 38 is rotatably arranged between the first variable diameter wheel 35 and the second variable diameter wheel 36.

[0062] By controlling the distance between the first variable diameter wheel 35 and the second variable diameter wheel 36, the equivalent diameter at this position can be changed. Under the elastic force of the variable diameter wheel pre-tightening spring 37, the equivalent diameter of the driven variable diameter assembly 31 always has a tendency to increase. And under the linkage effect of the trapezoidal drive belt 38, the equivalent diameter of the driving variable diameter assembly 32 always has a tendency to decrease. Therefore, when the ramp slider 46 and the telescopic ramp rod 42 are not in contact, the distance between the third variable diameter wheel 39 and the fourth variable diameter wheel 40 is the largest.

[0063] The active diameter-changing assembly 32 includes a third diameter-changing wheel 39, a fourth diameter-changing wheel 40, a telescopic cavity 41, a telescopic ramp rod 42, and a second hydraulic pipeline 43. The third diameter-changing wheel 39 is slidably disposed on the rotating main shaft 8. The third diameter-changing wheel 39 can axially slide relative to the rotating main shaft 8 and cannot rotate relative to the rotating main shaft 8. The fourth diameter-changing wheel 40 is fixedly connected to the rotating main shaft 8. The trapezoidal drive belt 38 is rotatably disposed between the third diameter-changing wheel 39 and the fourth diameter-changing wheel 40. The telescopic cavity 41 is fixedly connected to the hollow groove portion 13. The telescopic ramp rod 42 is engaged and slidably disposed in the telescopic cavity 41. Symmetrically arranged on the third diameter-changing wheel 39 are ramp sliders 46 that cooperate with the telescopic ramp rod 42. The ramp sliders 46 are slidably disposed in the hollow groove portion 13. The telescopic cavity 41 and the hollow inner tube 25 are connected through the second hydraulic pipeline 43 in a through manner.

[0064] The two diameter-changing wheel groups are driven by the trapezoidal drive belt 38. Therefore, when the distance between the third diameter-changing wheel 39 and the fourth diameter-changing wheel 40 decreases, the distance between the first diameter-changing wheel 35 and the second diameter-changing wheel 36 will necessarily increase; when the distance between the third diameter-changing wheel 39 and the fourth diameter-changing wheel 40 increases, the distance between the first diameter-changing wheel 35 and the second diameter-changing wheel 36 will also decrease under the elastic force of the diameter-changing wheel pre-tightening spring 37; therefore, by adjusting the distance between the third diameter-changing wheel 39 and the fourth diameter-changing wheel 40, the adaptive adjustment of the transmission ratio of the adaptive speed regulation drive mechanism 3 can be achieved.

[0065] The gravity-sensing magnetic pickup mechanism 2 includes an elastic lateral movement compensation assembly 14, a magnetic adsorption lifting assembly 15, and a gravity-sensing assembly 16. The elastic lateral movement compensation assembly 14 is slidably disposed in the rotating frame assembly 7. The magnetic adsorption lifting assembly 15 is rotatably disposed on the elastic lateral movement compensation assembly 14. The gravity-sensing assembly 16 is disposed on the magnetic adsorption lifting assembly 15.

[0066] The elastic lateral movement compensation assembly 14 includes a lateral movement slider 17 and a lateral movement return spring 18. The lateral movement slider 17 is engaged and slidably disposed in the bracket chute portion 12. The lateral movement return spring 18 is disposed between the end wall of the hollow groove portion 13 and the lateral movement slider 17.

[0067] Through the lateral movement compensation of the lateral movement slider 17, during the material loading and unloading, the magnetic carrier plate 54 can be allowed to pass, and the rotating bracket 9 can be in lateral movement contact with or separated from the support slide plate 52, so as to achieve a smooth connection between the electroplating stage and the material loading and unloading stage.

[0068] The magnetic adsorption type lifting assembly 15 includes a lifting cross bar 19, a lifting plate 20 and a lifting plate return spring 21. The lifting cross bar 19 is rotatably arranged in the transverse movement slider 17. One end of the lifting cross bar 19 is provided with a hollow inner pipe 25. The central position of the lifting cross bar 19 is provided with an induction cavity pipe 26. The lifting cross bar 19 is symmetrically provided with sliding sleeve parts 27 on both sides of the induction cavity pipe 26. The lifting plate 20 is symmetrically provided with lifting guide rods 28. The lifting plate 20 is clamped and slidably arranged in the sliding sleeve parts 27 through the lifting guide rods 28. A magnetic adsorption plate 29 is arranged at the bottom of the lifting plate 20. The lifting plate return spring 21 is arranged between the lifting guide rods 28 and the sliding sleeve parts 27.

[0069] The lifting cross bar 19 and the lifting plate 20 will maintain a vertical state, and the lifting plate 20 will slide relative to the lifting cross bar 19 under the gravity of the magnetic load plate 54. The sliding amplitude between the lifting plate 20 and the lifting cross bar 19 is determined by the weight of the magnetic load plate 54. Through the sliding amplitude of the lifting plate 20, the weight of the currently picked magnetic load plate 54 can be feedback. In the case where the shape of the magnetic load plate 54 is simple and unified, the mass and surface area of the workpiece loaded on the magnetic load plate 54 can be reflected.

[0070] The gravity induction assembly 16 includes a piston part 22, a sliding rod part 23 and a first hydraulic pipeline 24. The piston part 22 is clamped and slidably arranged in the induction cavity pipe 26. One end of the sliding rod part 23 is fixedly connected to the piston part 22, and the other end of the sliding rod part 23 is fixedly connected to the lifting plate 20. The first hydraulic pipeline 24 and the hollow inner pipe 25 are connected through the first hydraulic pipeline 24.

[0071] When the lifting plate 20 slides relative to the lifting cross bar 19, it can simultaneously control the sliding of the piston part 22 in the induction cavity pipe 26, and then change the transmission ratio of the adaptive speed regulation drive mechanism 3 through the hydraulic induction and drive method, so as to achieve the technical purpose of adaptively adjusting the rotation speed of the rotary frame assembly 7 under the condition that the rotation speed of the rotary drive motor 34 remains unchanged.

[0072] During specific use, first, the user needs to start the rotary drive motor 34. During the continuous and stable rotation of the rotary drive motor 34, the rotary frame assembly 7 is driven to rotate integrally through the driven variable diameter assembly 31 and the active variable diameter assembly 32. While the rotary main shaft 8 is rotating, it will also drive the driven wheel shaft 50 to rotate through the active synchronous pulley 49 and the synchronous belt 51. The driven wheel shaft 50 will drive the loading and unloading tooth belt 53 to make a rotary motion. At this time, the magnetic load plate 54 is placed between the loading and unloading tooth belt 53 and the support sliding plate 52 through an external picking unit. Then, through the continuous movement of the loading and unloading tooth belt 53, the magnetic load plate 54 on one side can be conveyed towards the position close to the rotary frame assembly 7, and the magnetic load plate 54 on the other side can be conveyed towards the direction away from the rotary frame assembly 7.

[0073] During the continuous rotation of the rotating rack assembly 7, since the hoisting cross bar 19 can rotate freely in the transverse sliding block 17, under the pulling action of the hoisting plate 20 and the magnetic carrier plate 54, both the hoisting cross bar 19 and the hoisting plate 20 always remain in the vertical state.

[0074] The magnetic carrier plate 54 on the loading side just meets the hoisting plate 20 on the loading side at the horizontal position. The two are in contact and connected under the magnetic attraction force between the magnetic attraction plate 29 and the magnetic carrier plate 54. At this time, the deformation of the transverse movement return spring 18 allows the transverse sliding block 17 to slide slightly. After the magnetic carrier plate 54 disengages from the feeding and discharging toothed belt 53, the transverse sliding block 17 will return to its original position;

[0075] As the feeding and discharging toothed belt 53 rotates, after the magnetic carrier plate 54 on the loading side disengages from the support sliding plate 52, it will separate from the feeding and discharging toothed belt 53 and thus be transferred to the hoisting plate 20;

[0076] Under the gravity of the magnetic carrier plate 54, the hoisting plate 20 will slide relative to the hoisting cross bar 19 against the elastic force of the hanging plate return spring 21. And the heavier the weight of the magnetic carrier plate 54, the greater the sliding amplitude of the hoisting plate 20 relative to the hoisting cross bar 19; when the electroplated workpieces are all of simple standard shapes, the heavier the weight, the larger the specification and surface area of the workpiece, and the longer the time required for the electroplating process.

[0077] When the hoisting plate 20 slides relative to the hoisting cross bar 19, the piston part 22 will also slide relative to the induction cavity tube 26. At this time, the liquid in the induction cavity tube 26 will enter the telescopic cavity 41 through the first hydraulic pipeline 24, the hollow inner tube 25 and the second hydraulic pipeline 43, so that the telescopic ramp rod 42 extends. When the telescopic ramp rod 42 extends, it will push the third variable diameter wheel 39 to slide towards the direction close to the fourth variable diameter wheel 40 through the ramp cooperation between itself and the ramp sliding block 46; the heavier the mass of the magnetic carrier plate 54, the greater the extension amplitude of the telescopic ramp rod 42, and at the same time the smaller the distance between the third variable diameter wheel 39 and the fourth variable diameter wheel 40;

[0078] When the distance between the third variable diameter wheel 39 and the fourth variable diameter wheel 40 decreases, the equivalent diameter of the active variable diameter assembly 32 increases, and the total length of the trapezoidal drive belt 38 remains unchanged. Therefore, the equivalent diameter of the driven variable diameter assembly 31 will decrease. At this time, with the change of the transmission ratio of the adaptive speed regulation drive mechanism 3, when the rotational speed of the rotary drive motor 34 remains unchanged, the rotational speed of the rotary main shaft 8 will also decrease, so as to achieve the purpose of extending the electroplating time; the heavier the mass of the magnetic carrier plate 54, the longer the electroplating time.

[0079] Since at most one magnetic carrier plate 54 is adsorbed at the support crossbar portion 11 at the same time, the slide rod portion 23 and the telescopic ramp rod 42 on the other side are in the retracted state and will not affect the transmission ratio of the adaptive speed regulation drive mechanism 3; and the transmission ratio of the adaptive speed regulation drive mechanism 3 is related to the mass of the magnetic carrier plate 54 in the electroplating process.

[0080] After the electroplated workpiece is lifted out of the liquid, it will contact the loading and unloading tooth belt 53 on the blanking side and engage with it through the engaging tooth portion 56. At this time, driven by the lateral movement of the loading and unloading tooth belt 53, the lateral movement slider 17 will overcome the elastic force of the lateral movement return spring 18 and move laterally, causing the magnetic carrier plate 54 to slide onto the support slide plate 52, and then move to the next process along with the loading and unloading tooth belt 53 on the blanking side.
