[0013] Furthermore, the electrical column and the electrical ring are respectively connected to the two ends of the electromagnet's same-level wire that are disconnected.

[0014] Beneficial Effects

[0015] 1. When the device is in use, the lifting control component can control the lifting of the bracket component, so as to realize the operation of inserting and taking out the workpiece into and out of the electroplating liquid. The use is convenient and flexible, and the depth control component can accurately control the lifting control component to drive the bracket component to insert the workpiece into the electroplating liquid, thereby realizing the use requirements of precise processing of the required electroplating parts of the workpiece. At the same time, the insertion depth can be freely adjusted and set, which can adapt to the processing operation of electroplating deposition to prepare Pt thin films for workpieces of different types and electroplating preparation requirements, thereby improving the flexibility, accuracy, adaptability and practicality of the device.

[0016] 2. The lifting control assembly can control the lifting of the bracket assembly to realize the operation of inserting and removing the workpiece into the electroplating liquid. When the driving motor rotates, the driving gear of the driving motor can drive the control disk to rotate synchronously through the driven gear disk. When the control disk rotates, the synchronous groove can drive the adaptation block to rotate synchronously through the regular polygonal block of the adaptation block. When the adaptation block rotates, the clutch tooth groove can drive the driving threaded rod to rotate through the clutch gear. When the driving threaded rod rotates, it can drive the synchronous bracket to lift and lower through the rod body thread, thereby realizing the operation of inserting and removing the workpiece clamped by the workpiece fixture into the electroplating liquid for processing. It is flexible and convenient to use.

[0017] 3. The depth control component can limit the maximum distance (limit) that the lifting control component can move down to drive the bracket component, so as to realize the function of accurately controlling the depth of the workpiece inserted into the electroplating solution, so as to accurately perform electroplating processing on the corresponding parts of the workpiece. The liquid level float can float on the top of the liquid level of the solution pool and can change with the change of the liquid level of the solution inside the solution pool. Therefore, when the bracket assembly moves down under the drive of the lifting control component, the follower block can synchronously follow the bracket assembly to move down. When the follower block contacts the liquid level float, the two vertical rods of the electrical connecting rod are respectively in contact with the electrical column and the electrical ring, thereby connecting the circuit of the electromagnet. After the electromagnet is energized, the magnetic force generated passes through the linkage block of the magnetic material. The adapting block is attracted to move the adapting block upward. When the adapting block moves upward, the clutch tooth groove disengages from the outside of the clutch gear, so that the adapting block no longer continues to transmit the drive threaded rod, preventing the drive threaded rod from continuing to rotate forward (here, the rotation direction when the drive threaded rod drives the synchronous bracket to move downward is the forward direction) to drive the synchronous bracket to continue to move downward, and thereafter when the control disk continues to rotate forward, the one-way clamping block and the one-way reset tooth groove can avoid each other under the mutual squeezing action of the bevel edges, so that the control disk still cannot drive the drive threaded rod to rotate forward when it rotates forward, thereby realizing the function of accurately controlling the downward movement length of the bracket assembly, and can accurately control the depth of the workpiece inserted into the electroplating liquid, with stable use and extremely high accuracy.

[0018] 4. After the depth limit function is triggered, the device can still realize the operation of lifting and resetting the bracket assembly to lift the workpiece out of the electroplating liquid by driving the control disk to reverse through the driving motor. After the depth limit function is triggered and the control disk is reversed, the straight edge of the one-way clamping block can be engaged with the straight edge of the tooth groove of the one-way reset tooth groove under the action of the positioning top spring, thereby driving the driving threaded rod to reverse synchronously, so that the driving threaded rod can drive the synchronous bracket to move up through the rod body thread when reversing to lift the workpiece out of the electroplating liquid, and in this process, the follower block and the liquid level float block are no longer in contact, thereby disconnecting the power supply of the electromagnet. Thereafter, the adaptation block can be reset under the action of the combined top spring so that the clutch tooth groove is reinserted into the outside of the clutch gear, so as to drive the synchronous bracket to move down when the threaded rod is driven to rotate forward next time. It is easy to use and has strong flexibility.

[0019] 5. The device can freely adjust the limit depth of the workpiece inserted into the electroplating liquid by adjusting the threaded rod, so that it can adapt to the electroplating processing operations on workpieces of different types and preparation requirements. When the adjusting threaded rod is rotated, the adjusting threaded rod can move up and down inside the synchronous bracket, thereby changing the initial use height of the follower block, that is, changing the depth of the workpiece inserted into the electroplating liquid when the follower block contacts the liquid level float, and the adaptability is extremely strong.

Its specific structure and working principle are existing mature technologies and will not be repeated here.

[0037] Among them, a driving gear 2011 is provided at one end of the rotating shaft of the driving motor 201, and a driven toothed disc 2021 is provided on the outside of the control disc 202.

The cross-sectional shape of the block at the bottom of the adaptation block 203 is a regular polygon, and a synchronous groove 2022 is provided inside the control disc 202. The regular polygonal block at the bottom of the adaptation block 203 is inserted into the inner part of the synchronous groove 2022.

[0038] Among them, a linkage block 2033 made of magnetic material is provided on the top of the adaptation block 203. In use, the depth control component 4 can limit the maximum distance (limit) that the lifting control component 2 can drive the support component 3 to move downward, so as to realize the function of accurately controlling the depth of the workpiece inserted into the electroplating liquid, so as to accurately perform electroplating processing on the corresponding part of the workpiece. The liquid level float 403 can float on the top of the liquid level of the solution pool 101, and can change with the change of the liquid level of the solution inside the solution pool 101, so that when the support component 3 moves downward under the drive of the lifting control component 2, the follower block 402 can synchronously follow the support component 3 to move downward. When the follower block 402 contacts the liquid level float 403, the two vertical rods of the electrical connecting rod 4031 are respectively in contact with the electrical column 4021 and the electrical ring 4022, thereby connecting the circuit of the electromagnet 103. After the electromagnet 103 is energized, the magnetic force is generated to attract the adaptation block 203 through the linkage block 2033 made of magnetic material, so that the adaptation block 203 moves upward. The adaptation block 203 moves upward. When moving, the clutch tooth groove 2031 is disengaged from the outside of the clutch gear 2041, so that the adaptation block 203 no longer continues to transmit the drive threaded rod 204, preventing the drive threaded rod 204 from continuing to rotate forward (here, the rotation direction when the drive threaded rod 204 drives the synchronous bracket 301 to move downward is the forward direction) to drive the synchronous bracket 301 to continue to move downward. The rod body of the drive threaded rod 204 is provided with a one-way reset tooth groove 2042, and the control panel 202 is internally plugged with a one-way block 2023. The one-way reset tooth groove The cross-sectional shapes of the single tooth groove 2042 and the outer end of the one-way block 2023 are both right-angled triangles, and thereafter when the control disk 202 continues to rotate forward, the one-way block 2023 and the one-way reset tooth groove 2042 can avoid each other under the mutual squeezing action of the hypotenuse, so that the control disk 202 still cannot drive the driving threaded rod 204 to rotate forward when rotating forward, thereby realizing the function of accurately controlling the downward movement length of the bracket assembly 3, and can accurately control the depth of the workpiece inserted into the electroplating liquid, with stable use and extremely high accuracy.

[0039] Among them, a positioning top spring 20231 is provided inside the one-way clamping block 2023, and the two ends of the positioning top spring 20231 are respectively fixedly connected to the inside of the one-way clamping block 2023 and the inside of the control disk 202.

A combining top spring 2032 is provided on the top of the adaptation block 203, and the two ends of the combining top spring 2032 are respectively against the bottom of the electromagnet 103 and the inside of the adaptation block 203. Thereafter, the adaptation block 203 can be reset under the action of the combining top spring 2032 so that the clutch tooth groove 2031 is reinserted into the outside of the clutch gear 2041, so as to drive the synchronous bracket 301 to move downward when the threaded rod 204 is driven to rotate forward next time.

In use, the device can freely adjust the limiting depth of the workpiece inserted into the electroplating liquid by adjusting the threaded rod 401, so as to adapt to the electroplating processing operations on workpieces of different types and preparation requirements. When the adjusting threaded rod 401 is rotated, the adjusting threaded rod 401 can move up and down inside the synchronous bracket 301, thereby changing the initial use height of the follower block 402, that is, changing the depth of the workpiece inserted into the electroplating liquid when the follower block 402 contacts the liquid level float 403, and the adaptability is extremely strong.

[0041] Specific usage and function of this embodiment: In the present invention, firstly, the maximum insertion depth of the workpiece of the device is adjusted according to the workpiece type and preparation requirements, and the limit depth of the workpiece inserted into the electroplating liquid can be freely adjusted by adjusting the threaded rod 401. When the threaded rod 401 is rotated, the threaded rod 401 can move up and down inside the synchronous bracket 301, thereby changing the initial use height of the follower block 402, that is, changing the depth of the workpiece inserted into the electroplating liquid when the follower block 402 contacts the liquid level float 403, fixing the workpiece at the bottom of the workpiece fixture 303, and then controlling the lifting and lowering of the bracket assembly 3 through the lifting control assembly 2 to realize the operation of inserting and removing the workpiece into the electroplating liquid. When the drive motor 201 rotates, The driving gear 2011 of the driving motor 201 can drive the control disk 202 to rotate synchronously through the driven gear disk 2021. When the control disk 202 rotates, the synchronous groove 2022 can drive the adaptation block 203 to rotate synchronously through the regular polygonal block of the adaptation block 203, so that when the adaptation block 203 rotates, the clutch tooth groove 2031 can drive the driving threaded rod 204 to rotate through the clutch gear 2041. When the driving threaded rod 204 rotates, it can drive the synchronous bracket 301 to rise and fall through the rod body thread, thereby realizing the operation of inserting and removing the workpiece clamped and fixed by the workpiece clamp 303 from the electroplating liquid for internal processing, and in the process of inserting the workpiece into the electroplating liquid, the depth control component 4 can limit the maximum downward movement of the bracket component 3 driven by the lifting control component 2 The maximum distance (limit) can be achieved, so that the function of accurately controlling the depth of the workpiece inserted into the electroplating solution can be realized, so that the corresponding part of the workpiece can be accurately electroplated. The liquid level float 403 can float on the top of the liquid level of the solution pool 101, and can change with the change of the liquid level of the solution in the solution pool 101. Therefore, when the support assembly 3 moves downward under the drive of the lifting control assembly 2, the follower block 402 can synchronously follow the support assembly 3 to move downward. When the follower block 402 contacts the liquid level float 403, the two vertical rods of the electrical connecting rod 4031 are respectively in contact with the electrical column 4021 and the electrical ring 4022, thereby connecting the circuit of the electromagnet 103. After the electromagnet 103 is energized, the magnetic force generated by the linkage block 2033 of the magnetic material will adapt to the block 20 3 is attracted to make the adapting block 203 move upward. When the adapting block 203 moves upward, the clutch tooth groove 2031 escapes from the outside of the clutch gear 2041, so that the adapting block 203 no longer continues to transmit the driving threaded rod 204, preventing the driving threaded rod 204 from continuing to rotate forward (here, the rotation direction when the driving threaded rod 204 drives the synchronous bracket 301 to move downward is the forward direction) to drive the synchronous bracket 301 to continue to move downward, and thereafter when the control disk 202 continues to rotate forward, the one-way block 2023 and the one-way reset tooth groove 2042 can avoid each other under the mutual squeezing effect of the oblique edges, so that the control disk 202 still cannot drive the driving threaded rod 204 to rotate forward when it rotates forward, thereby realizing the function of accurately controlling the downward movement length of the bracket assembly 3.The insertion depth of the workpiece into the electroplating liquid can be accurately controlled. After the depth limit function is triggered, the control disk 202 can be reversed by driving the motor 201 to still realize the operation of lifting the support assembly 3 up and resetting to lift the workpiece out of the electroplating liquid. After the depth limit function is triggered and the control disk 202 is reversed, the one-way clamping block 2023 can be engaged with the straight edge of the tooth groove of the one-way reset tooth groove 2042 by the action of the positioning top spring 20231, thereby driving the driving threaded rod 204 to synchronously reverse. The threaded rod 204 is driven to rotate in reverse direction, so that the synchronous bracket 301 can be driven to move upward through the rod body thread to lift the workpiece out of the electroplating liquid. In this process, the follower block 402 is no longer in contact with the liquid level float 403, thereby disconnecting the power supply of the electromagnet 103. After that, the adaptable block 203 can be reset under the action of the top spring 2032 so that the clutch tooth groove 2031 is reinserted into the outside of the clutch gear 2041, so that the synchronous bracket 301 can be driven to move downward to realize the electroplating processing operation when the threaded rod 204 is driven to rotate forward next time.
