Description

Technical Field

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

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain materials using the principle of electrolysis. It is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts. 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 immersion 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 of such parts, the heavier the weight, and the larger the surface area of ​​the workpiece. At this time, the time required for electroplating must be appropriately extended. If workpieces of different specifications are electroplated for the same time, quality defects such as the electroplating layer being too thin (insufficient protective ability) or too thick (cracks, peeling) may occur.

[0004] In order to ensure the continuity of the process, the existing electroplating production lines are generally connected to the loading and unloading conveyor lines through a rotating bracket. The workpieces are immersed in the plating solution and taken out by the rotation of the bracket. However, if workpieces of different specifications are encountered, the rotation speed of the rotating bracket and the speed of the loading and unloading conveyor lines need to be manually adjusted. This conventional operation method not only requires the motor used for driving to be a more expensive servo motor, but also requires the control system to perform frequent automatic or manual control, which is costly, structurally complex and difficult to operate. 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 adjustment support that can adaptively adjust the electroplating time according to the weight difference of workpieces of different specifications; this scheme is based on the characteristic that "the simpler the shape of the workpiece, the heavier the mass and the larger the surface area, and the longer the electroplating time is required". By sensing the mass of the workpiece, the transmission ratio of the adaptive speed regulation drive mechanism is adaptively adjusted, and by automatically compensating for the electroplating time, the impact of this process on the quality of the electroplating layer when the specifications of the workpiece change can be significantly reduced; not only that, the present invention also uses the scheme of alternating loading and unloading to pick up only one magnetic carrier plate at the same 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 at the same time.

[0006] The rotating frame assembly drives the loading and unloading assembly to rotate through the belt transmission assembly, so that when the rotation speed of the rotating frame assembly changes, the loading and unloading speed of the loading and unloading assembly can also change accordingly, thereby ensuring that no matter whether the rotation speed of the rotating frame assembly is increased or decreased, the loading and unloading speed of the loading and unloading assembly can remain matched therewith.

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

[0008] The gravity-sensing magnetic pickup mechanism can sense the weight of the magnetic carrier plate and reflect the surface area of ​​the workpiece. When the surface area of ​​the workpiece changes, the rotation speed of the rotating frame assembly can be automatically adaptively adjusted while the rotating drive motor 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.

[0009] Preferably, the rotating frame assembly comprises 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 fixed to the rotating main shaft, the rotating brackets are connected and fixed by a transverse connecting rod, the rotating brackets are symmetrically provided with bracket cross bar portions, the ends of the bracket cross bar portions are provided with bracket sliding groove portions, and one of the rotating brackets is provided with a hollow groove portion.

[0010] Two bracket cross bars are symmetrically arranged, so that the rotating bracket can alternately pick up and release the magnetic carrier plate during the rotation process, which not only effectively improves the efficiency, but also at the same time, at most only one bracket cross bar will carry materials. Therefore, when the rotation speed of the rotating frame assembly is controlled by the weight of the magnetic carrier plate, the embarrassing situation of the sensing results of multiple heavy objects interfering with each other can be avoided.

[0011] Furthermore, the gravity-sensing magnetic pickup mechanism includes an elastic lateral movement compensation component, a magnetic lifting component and a gravity-sensing component. The elastic lateral movement compensation component is slidably arranged in the rotating frame component, the magnetic lifting component is rotatably arranged on the elastic lateral movement compensation component, and the gravity-sensing component is arranged on the magnetic lifting component.

[0012] Preferably, the elastic transverse displacement compensation assembly comprises a transverse displacement slider and a transverse displacement return spring, the transverse displacement slider is slidably engaged in the bracket slide groove portion, and the transverse displacement return spring is arranged between the end wall of the hollow groove portion and the transverse displacement slider.

[0013] Through the lateral compensation of the lateral sliding block, the magnetic carrier plate can be allowed to pass when picking up and placing materials, and the rotating bracket and its own lateral movement can contact or detach from the supporting slide, thereby achieving a smooth connection between the electroplating stage and the picking up and placing stage.

[0014] As a further preferred embodiment of the present invention, the magnetic suspension assembly includes a suspension crossbar, a suspension plate and a suspension plate reset spring, the suspension crossbar is rotatably arranged in the transverse sliding block, one end of the suspension crossbar is provided with a hollow inner tube, the center of the suspension crossbar is provided with a sensing cavity tube, and the suspension crossbar is symmetrically provided with sliding sleeves on both sides of the sensing cavity tube. Suspension guide rods are symmetrically arranged on the suspension plate, the suspension plate is slidably arranged in the sliding sleeve part through the clamping of the suspension guide rods, a magnetic suction plate is arranged at the bottom of the suspension plate, and the suspension plate reset spring is arranged between the suspension guide rod and the sliding sleeve part.

[0015] The lifting cross bar and the lifting plate will remain in a vertical state, and the lifting plate will slide relative to the lifting cross bar under the gravity of the magnetic carrier plate. The sliding amplitude between the lifting plate and the lifting cross bar is determined by the weight of the magnetic carrier plate. The weight of the currently picked up magnetic carrier plate can be fed back through the sliding amplitude of the lifting plate. When the shape of the magnetic carrier plate is simple and uniform, the mass and surface area of ​​the workpiece loaded on the magnetic carrier plate can be reflected.

[0016] As a further preferred embodiment of the present invention, the gravity sensing component includes a piston part, a sliding rod part and a first hydraulic pipeline. The piston part is slidably arranged in the sensing cavity tube, one end of the sliding rod part is fixedly connected to the piston part, and the other end of the sliding rod part is fixedly connected to the hanging plate. The first hydraulic pipeline and the hollow inner tube are connected through the first hydraulic pipeline.

[0017] When the lifting plate slides relative to the lifting cross bar, the sliding of the piston part in the sensing cavity can be controlled at the same time, and then the transmission ratio of the adaptive speed regulation drive mechanism is changed through hydraulic sensing and driving, thereby achieving the technical purpose of adaptively adjusting the rotation speed of the rotating frame assembly when the rotation speed of the rotating drive motor remains unchanged.

[0018] Furthermore, the adaptive speed regulation drive mechanism includes a driving component, a driven diameter-changing component and an active diameter-changing component, the driving component is arranged on the side support plate, the driven diameter-changing component is arranged on the driving component, and the active diameter-changing component is arranged on the rotating frame component.

[0019] Preferably, the driving assembly comprises a motor bracket and a rotary driving motor, wherein the motor bracket is fixedly connected to the side supporting plate, the rotary driving motor is arranged on the motor bracket, the rotary driving motor is provided with a driving spindle, and the driving spindle is provided with a spring baffle.

[0020] As a further preferred embodiment of the present invention, the driven reducing wheel assembly includes a first reducing wheel, a second reducing wheel, a reducing wheel pre-tensioning spring and a trapezoidal transmission belt, the first reducing wheel is fixedly connected to the driving main shaft, the second reducing wheel is slidably arranged on the driving main shaft, the second reducing wheel can slide axially relative to the driving main shaft, the second reducing wheel cannot rotate relative to the driving main shaft, the reducing wheel pre-tensioning spring is arranged between the second reducing wheel and the spring baffle, and the trapezoidal transmission belt is rollingly arranged between the first reducing wheel and the second reducing wheel.

[0021] By controlling the spacing between the first reducing wheel and the second reducing wheel, the equivalent diameter at this position can be changed. Under the elastic force of the reducing wheel preload spring, the equivalent diameter of the driven reducing assembly always tends to increase, and under the linkage action of the trapezoidal transmission belt, the equivalent diameter of the active reducing assembly always tends to decrease. Therefore, when the ramp slider and the telescopic ramp rod are not in contact, the spacing between the third reducing wheel and the fourth reducing wheel is the largest.

[0022] As a further preferred embodiment of the present invention, the active variable diameter assembly includes a third variable diameter wheel, a fourth variable diameter wheel, a telescopic cavity, a telescopic ramp rod and a second hydraulic pipeline. The third variable diameter wheel is slidably arranged on the rotating main shaft, the third variable diameter wheel can slide axially relative to the rotating main shaft, and the third variable diameter wheel cannot rotate relative to the rotating main shaft. The fourth variable diameter wheel is fixedly connected to the rotating main shaft, the trapezoidal transmission belt is rotatably arranged 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 ramp rod is snap-fitted and slidably arranged in the telescopic cavity, the third variable diameter wheel is symmetrically provided with a ramp slider cooperating with the telescopic ramp rod, the ramp slider is slidably arranged in the hollow groove portion, and the telescopic cavity and the hollow inner tube are connected through the second hydraulic pipeline.

[0023] The two groups of variable diameter wheel groups 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 inevitably 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 preload spring; therefore, by adjusting the distance between the third variable diameter wheel and the fourth variable diameter wheel, the transmission ratio of the adaptive speed regulation drive mechanism can be adaptively adjusted.

[0024] Furthermore, the loading and unloading mechanism includes a belt transmission assembly and a loading and unloading assembly, and the loading and unloading assembly is arranged on the electroplating liquid storage tank; the belt transmission assembly includes an active synchronous wheel, a driven wheel shaft and a synchronous belt, the active synchronous wheel is fixedly connected to the rotating main shaft, and the driven wheel shaft is rotatably arranged in the side support plate, and the driven wheel shaft and the active synchronous wheel are connected by a synchronous belt transmission.

[0025] Through the transmission of the belt drive assembly, on the one hand, the movement direction of the two groups of supporting slides can be adapted to the rotation direction of the rotating frame assembly, and on the other hand, the movement speed of the two groups of supporting slides can be kept matching the rotation speed of the rotating frame assembly, so that when the rotation speed of the rotating spindle changes, the loading and unloading speed of the loading and unloading toothed belt can still be kept adapted to it.

[0026] Preferably, the loading and unloading assembly includes a supporting slide plate, an loading and unloading toothed belt and a magnetic carrier plate, the supporting slide plate is fixedly connected to the electroplating liquid storage tank, the loading and unloading toothed belt is rollingly arranged on the driven wheel shaft, trapezoidal end heads are arranged at both ends of the magnetic carrier plate, the top of the trapezoidal end heads is provided with meshing teeth matching the loading and unloading toothed belt, and the magnetic carrier plate is slidably arranged on the supporting slide plate.

[0027] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The gravity-sensing magnetic pickup mechanism can sense the weight of the magnetic carrier plate and reflect the surface area of ​​the workpiece. When the surface area of ​​the workpiece changes, the rotation speed of the rotating frame assembly can be automatically and adaptively adjusted while the rotating drive motor 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 the electroplating of different workpieces.

[0028] (2) The bracket cross bar is symmetrically provided with two, so that the rotating bracket can alternately pick up and release the magnetic carrier plate during the rotation process, which not only effectively improves the efficiency, but also at the same time, at most only one bracket cross bar will carry materials. Therefore, when the rotation speed of the rotating frame assembly is controlled by the weight of the magnetic carrier plate, the embarrassing situation that the sensing results of multiple heavy objects interfere with each other can be avoided.

[0029] (3) Through the lateral compensation of the lateral sliding block, the magnetic carrier plate can be allowed to pass when picking up and placing materials, and the rotating bracket and its own lateral movement can contact or detach from the supporting slide, thereby achieving a smooth connection between the electroplating stage and the picking up and placing stage.

[0030] (4) The lifting bar and the lifting plate will remain in a vertical state, and the lifting plate will slide relative to the lifting bar under the gravity of the magnetic carrier plate. The sliding amplitude between the lifting plate and the lifting bar is determined by the weight of the magnetic carrier plate. The weight of the currently picked up magnetic carrier plate can be fed back through the sliding amplitude of the lifting plate. When the shape of the magnetic carrier plate is simple and uniform, the mass and surface area of ​​the workpiece loaded on the magnetic carrier plate can be reflected.

[0031] (5) When the lifting plate slides relative to the lifting cross bar, it can simultaneously control the sliding of the piston part in the sensing cavity tube, and then change the transmission ratio of the adaptive speed regulation drive mechanism through hydraulic sensing and driving, thereby achieving the technical purpose of adaptively adjusting the rotation speed of the rotating frame assembly when the rotation speed of the rotating drive motor remains unchanged.

[0032] (6) By controlling the spacing between the first reducing wheel and the second reducing wheel, the equivalent diameter at that position can be changed. Under the elastic force of the reducing wheel preload spring, the equivalent diameter of the driven reducing assembly always tends to increase, and under the linkage action of the trapezoidal transmission belt, the equivalent diameter of the active reducing assembly always tends to decrease. Therefore, when the ramp slider and the telescopic ramp rod are not in contact, the spacing between the third reducing wheel and the fourth reducing wheel is the largest.

[0033] (7) The two groups of variable diameter wheels 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 inevitably 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 preload spring; therefore, by adjusting the distance between the third variable diameter wheel and the fourth variable diameter wheel, the transmission ratio of the adaptive speed regulation drive mechanism can be adaptively adjusted.

[0034] (8) Through the transmission of the belt drive assembly, on the one hand, the movement direction of the two groups of supporting slides can be adapted to the rotation direction of the rotating frame assembly, and on the other hand, the movement speed of the two groups of supporting slides can be kept matched with the rotation speed of the rotating frame assembly, so that when the rotation speed of the rotating spindle changes, the loading and unloading speed of the loading and unloading toothed belt can still be kept adapted to it.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] like Figure 1 to Figure 12 As 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] Through the transmission of the belt drive assembly 47, on the one hand, the movement direction of the two groups of supporting slides 52 can be adapted to the rotation direction of the rotating frame assembly 7, and on the other hand, the movement speed of the two groups of supporting slides 52 can be kept matching the rotation speed of the rotating frame assembly 7, so that when the rotation speed of the rotating spindle 8 changes, the loading and unloading speed of the loading and unloading toothed belt 53 can still be kept adapted thereto.

[0046] The loading and unloading assembly 48 includes a supporting slide 52, a loading and unloading toothed belt 53 and a magnetic carrier plate 54. The supporting slide 52 is 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 arranged at both ends of the magnetic carrier plate 54. The top of the trapezoidal end head 55 is provided with a meshing tooth portion 56 matching the loading and unloading toothed belt 53. The magnetic carrier plate 54 is slidably arranged on the supporting slide 52.

[0047] The adaptive speed regulation drive mechanism 3 includes a driving component 30 , a driven diameter-changing component 31 and an active diameter-changing component 32 . The driving component 30 is arranged on the side support plate 6 , the driven diameter-changing component 31 is arranged on the driving component 30 , and the active diameter-changing component 32 is arranged on the rotating frame component 7 .

[0048] The driving assembly 30 includes a motor bracket 33 and a rotary driving motor 34 . The motor bracket 33 is fixedly connected to the side support plate 6 . The rotary driving motor 34 is arranged on the motor bracket 33 . The rotary driving motor 34 is provided with a driving spindle 44 . The driving spindle 44 is provided with a spring baffle 45 .

[0049] The driven reducing assembly 31 includes a first reducing wheel 35, a second reducing wheel 36, a reducing wheel pre-tensioning spring 37 and a trapezoidal transmission belt 38. The first reducing wheel 35 is fixedly connected to the driving main shaft 44, the second reducing wheel 36 is slidably arranged on the driving main shaft 44, the second reducing wheel 36 can slide axially relative to the driving main shaft 44, the second reducing wheel 36 cannot rotate relative to the driving main shaft 44, the reducing wheel pre-tensioning spring 37 is arranged between the second reducing wheel 36 and the spring baffle 45, and the trapezoidal transmission belt 38 is rollingly arranged between the first reducing wheel 35 and the second reducing wheel 36.

[0050] By controlling the spacing between the first reducing wheel 35 and the second reducing wheel 36, the equivalent diameter at this position can be changed. Under the elastic force of the reducing wheel preload spring 37, the equivalent diameter of the driven reducing assembly 31 always tends to increase, and under the linkage action of the trapezoidal transmission belt 38, the equivalent diameter of the active reducing assembly 32 always tends to decrease. Therefore, when the ramp slider 46 and the telescopic ramp rod 42 are not in contact, the spacing between the third reducing wheel 39 and the fourth reducing wheel 40 is the largest.

[0051] 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 arranged on the rotating main shaft 8. The third diameter-changing wheel 39 can slide axially relative to the rotating main shaft 8, and the third diameter-changing wheel 39 cannot rotate relative to the rotating main shaft 8.

The telescopic cavity 41 is fixedly connected to the hollow groove portion 13. The telescopic ramp rod 42 is slidably arranged in the telescopic cavity 41. The third diameter-changing wheel 39 is symmetrically provided with a ramp slider 46 that cooperates with the telescopic ramp rod 42. The ramp slider 46 is slidably arranged in the hollow groove portion 13. The telescopic cavity 41 and the hollow inner tube 25 are connected through the second hydraulic pipeline 43.

[0052] The two groups of variable diameter wheel groups are driven by a trapezoidal transmission belt 38. Therefore, when the distance between the third variable diameter wheel 39 and the fourth variable diameter wheel 40 decreases, the distance between the first variable diameter wheel 35 and the second variable diameter wheel 36 will inevitably increase; when the distance between the third variable diameter wheel 39 and the fourth variable diameter wheel 40 increases, the distance between the first variable diameter wheel 35 and the second variable diameter wheel 36 will also decrease under the elastic force of the variable diameter wheel preload spring 37; therefore, by adjusting the distance between the third variable diameter wheel 39 and the fourth variable diameter wheel 40, the transmission ratio of the adaptive speed regulation drive mechanism 3 can be adaptively adjusted.

[0053] The gravity-sensing magnetic pickup mechanism 2 includes an elastic lateral displacement compensation component 14, a magnetic lifting component 15 and a gravity-sensing component 16. The elastic lateral displacement compensation component 14 is slidably arranged in the rotating frame component 7, the magnetic lifting component 15 is rotatably arranged on the elastic lateral displacement compensation component 14, and the gravity-sensing component 16 is arranged on the magnetic lifting component 15.

[0054] The elastic transverse displacement compensation assembly 14 includes a transverse displacement slider 17 and a transverse displacement return spring 18 .

The suspension crossbar 19 is rotatably arranged in the transverse sliding block 17. A hollow inner tube 25 is arranged at one end of the suspension crossbar 19. A sensing cavity tube 26 is arranged at the center of the suspension crossbar 19. The suspension crossbar 19 is symmetrically provided with sliding sleeves 27 on both sides of the sensing cavity tube 26. Suspension guide rods 28 are symmetrically arranged on the suspension plate 20. The suspension plate 20 is slidably arranged in the sliding sleeve 27 through the engagement of the suspension guide rods 28. A magnetic suction plate 29 is arranged at the bottom of the suspension plate 20. The suspension plate reset spring 21 is arranged between the suspension guide rods 28 and the sliding sleeve 27.

[0057] The lifting cross bar 19 and the lifting plate 20 will remain in a vertical state, and the lifting plate 20 will slide relative to the lifting cross bar 19 under the action of the gravity of the magnetic carrier plate 54. The sliding amplitude between the lifting plate 20 and the lifting cross bar 19 is determined by the weight of the magnetic carrier plate 54. The weight of the currently picked up magnetic carrier plate 54 can be fed back through the sliding amplitude of the lifting plate 20. When the shape of the magnetic carrier plate 54 is simple and uniform, the mass and surface area of ​​the workpiece loaded on the magnetic carrier plate 54 can be reflected.

One end of the sliding rod portion 23 is fixedly connected to the piston portion 22, and the other end of the sliding rod portion 23 is fixedly connected to the hanging plate 20. The first hydraulic pipe 24 and the hollow inner tube 25 are connected through the first hydraulic pipe 24.

[0059] 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 sensing cavity 26, and then change the transmission ratio of the adaptive speed regulation drive mechanism 3 through hydraulic sensing and driving, thereby achieving the technical purpose of adaptively adjusting the rotation speed of the rotating frame assembly 7 when the rotation speed of the rotating drive motor 34 remains unchanged.

[0060] During specific use, the user first needs to start the rotary drive motor 34. During the continuous and stable rotation of the rotary drive motor 34, the rotating frame assembly 7 is rotated as a whole through the driven variable diameter assembly 31 and the active variable diameter assembly 32. While the rotating main shaft 8 is rotating, it will also rotate the driven wheel shaft 50 through the active synchronous wheel 49 and the synchronous belt 51. The driven wheel shaft 50 will make a rotational motion with the loading and unloading toothed belt 53. At this time, the magnetic carrier plate 54 is placed between the loading and unloading toothed belt 53 and the supporting slide plate 52 through the external picking unit. The continuous movement of the loading and unloading toothed belt 53 can transport the magnetic carrier plate 54 on one side toward a position close to the rotating frame assembly 7, and the magnetic carrier plate 54 on the other side can be transported toward a direction away from the rotating frame assembly 7.

[0061] During the continuous rotation of the rotating frame assembly 7 , since the lifting cross bar 19 can rotate freely in the transverse sliding block 17 , the lifting cross bar 19 and the lifting plate 20 are always kept in a vertical state under the pulling action of the lifting plate 20 and the magnetic carrier plate 54 .

[0062] The magnetic carrier plate 54 on the feeding side just meets the hanging plate 20 on the feeding side in a horizontal position, and the two are in contact and connected under the action of the magnetic attraction between the magnetic attraction plate 29 and the magnetic carrier plate 54. At this time, the deformation of the transverse return spring 18 can allow the transverse slider 17 to slide slightly. After the magnetic carrier plate 54 is separated from the loading and unloading toothed belt 53, the transverse slider 17 will be reset; As the loading and unloading toothed belt 53 rotates, the magnetic carrier plate 54 on the loading side will separate from the loading and unloading toothed belt 53 after being separated from the supporting slide plate 52, and thus transferred to the hanging plate 20; Under the action of gravity of the magnetic carrier plate 54, the hanging plate 20 will overcome the elastic force of the hanging plate return spring 21 and slide relative to the hanging cross bar 19, and the heavier the weight of the magnetic carrier plate 54, the greater the sliding range of the hanging plate 20 relative to the hanging cross bar 19; when the electroplated workpieces all have simple standard shapes, the heavier the weight, the larger the specifications of the workpiece, and the larger the surface area, the longer the time required for the electroplating process.

[0063] When the hoisting plate 20 slides relative to the hoisting cross bar 19, the piston part 22 will also slide relative to the sensing cavity tube 26. At this time, the liquid in the sensing cavity tube 26 will enter the telescopic cavity 41 through the first hydraulic pipe 24, the hollow inner pipe 25 and the second hydraulic pipe 43, so that the telescopic ramp rod 42 is extended. When the telescopic ramp rod 42 is extended, it will cooperate with the slope of the ramp slider 46 to push the third diameter-changing wheel 39 to slide in the direction close to the fourth diameter-changing wheel 40; the heavier the mass of the magnetic carrier plate 54, the greater the extension of the telescopic ramp rod 42, and the smaller the distance between the third diameter-changing wheel 39 and the fourth diameter-changing wheel 40. When the distance between the third reducing wheel 39 and the fourth reducing wheel 40 decreases, the equivalent diameter of the active reducing assembly 32 increases, while the total length of the trapezoidal transmission belt 38 remains unchanged. Therefore, the equivalent diameter of the driven reducing assembly 31 decreases. At this time, as the transmission ratio of the adaptive speed regulation drive mechanism 3 changes, the speed of the rotating spindle 8 also decreases when the speed of the rotating drive motor 34 remains unchanged, thereby achieving the purpose of extending the electroplating time; the heavier the mass of the magnetic carrier plate 54, the longer the electroplating time.

[0064] Since the magnetic carrier plate 54 is adsorbed on at most one bracket cross bar portion 11 at the same time, the sliding bar portion 23 and the telescopic ramp rod 42 on the other side are both in a 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 quality of the magnetic carrier plate 54 in the electroplating process.

[0065] After the electroplated workpiece is lifted out of the liquid, it will contact the loading and unloading toothed belt 53 on the unloading side and engage with it through the meshing tooth portion 56. At this time, driven by the lateral movement of the loading and unloading toothed belt 53, the lateral movement slider 17 will overcome the elastic force of the lateral movement reset spring 18 and move laterally, causing the magnetic carrier plate 54 to slide onto the supporting slide plate 52, and then move to the next process along the loading and unloading toothed belt 53 on the unloading side.
