Description

Technical Field

[0001] The present invention relates to the technical field of electroplating equipment, and in particular to a clamp for electroplating equipment. Background Art

[0002] The electroplating copper process involves depositing metallic copper via electrolysis onto an electroless copper layer to provide sufficient conductivity and thickness and prevent thermal and mechanical defects in the conductive circuit. The electroplating process involves adding a plating solution to a plating tank, using the circuit board as the cathode and an anode. After applying power and applying certain process adjustments, a copper layer is deposited onto the circuit board.

[0003] Anodic oxidation is the electrochemical oxidation of metals or alloys. It is a process in which a layer of oxide film is formed on the metal product (anode) under the action of an external current in the corresponding electrolyte and specific process conditions.

[0004] In a Chinese patent application with the number CN201620989239.0 and publication date of April 26, 2017, a clamp for anodizing is disclosed. The clamp comprises a mounting frame, a fixed clamp, a movable clamp, a reset mechanism for driving the movable clamp to reset, and a drive mechanism for driving the movable clamp to move up and down. The fixed clamp is fixed to the mounting frame; the fixed clamp comprises a fixed clamp plate and a fixed clamp arm, the fixed clamp plate being fixed to the lower end of the fixed clamp arm; the movable clamp comprises a movable clamp plate and a movable clamp arm, the movable clamp plate being fixed to the lower end of the movable clamp arm; the movable clamp plate and the fixed clamp plate are arranged vertically, forming a clamping gap between the movable clamp plate and the fixed clamp plate; the reset mechanism comprises a fixed plate connected to the mounting frame and a first spring disposed on the fixed plate, the lower end of the first spring being connected to the fixed plate and the upper end being connected to the movable clamp arm. The drive mechanism is used to drive the movable clamp to cooperate with the fixed clamp to change the size of the clamping gap, resulting in a simple and reliable structure. The reset mechanism is added to ensure that the movable clamp can be reset.

[0005] However, the clamp in this document does not have a fixing mechanism after the movable clamp and the fixed clamp clamp the aluminum plate. During operation, the movable clamp needs to be restricted by an external device to ensure stable clamping. Therefore, it will be restricted by the external device and cannot be well applied in unused environments. It is also easy to fail to stably clamp the aluminum plate due to changes in external restrictions during operation. Summary of the Invention

[0006] The present invention provides a clamp for electroplating equipment. The electroplating clamp of the present invention can stably clamp a workpiece, is not easy to disengage from the clamp during operation, and is simple and convenient to release the clamp.

[0007] To achieve the above-mentioned purpose, the technical solution of the present invention is: a fixture of electroplating equipment, including an electroplating fixture, wherein the electroplating fixture is arranged on the annular guide rail of the fully automatic electroplating equipment, and the electroplating fixture includes a base and a driving mechanism and a fixture group arranged on the base, wherein the driving mechanism is arranged at the upper end of one side of the base, and the fixture group is arranged at the lower end of one side of the base, and the driving mechanism is connected to the fixture group.

[0008] The driving mechanism includes a driving component and a reset component. The driving component is arranged at the top of the base, the reset component is connected to the clamp group, the reset component is arranged on one side of the base, and the driving component is arranged above the reset component; the reset component includes a reset driving plate, the reset driving plate is arranged on one side of the base and connected to the driving component, and the reset driving plate is connected to the clamp group.

[0009] The driving assembly includes a driving mounting plate, a driving wrench, a driving spring, a wrench connecting column, a driving top column, a driving shaft and a driving wheel. A driving groove is provided on the driving mounting plate, which passes through the two end surfaces of the driving rotating plate. A reset driving plate is provided on the front end surface of the driving mounting plate. A driving top column is provided on the reset driving plate located in the driving groove. The driving wrench is arranged on the rear end surface of the driving mounting plate through the wrench connecting column. A wrench driving part is provided on one end of the driving wrench. The wrench driving part extends to the driving groove. One side of the wrench driving part is connected to the side wall of the driving groove through a driving spring. A driving shaft is provided on the end of the wrench driving part away from the driving wrench. A driving wheel is provided on the driving shaft. The driving wheel is located in the driving groove and is connected to the driving top column in a conflicting manner.

[0010] In the above structure, the electroplating fixture moves along the annular guide rail to perform electroplating work, and the fixture group is driven by the driving component to clamp the workpiece. During operation, the fixture group clamps the workpiece and moves along the annular guide rail. During the movement, the fixture group performs electroplating on the workpiece. When clamping, the reset driving plate is manually pulled downward to allow the fixture group to clamp the workpiece. After the fixture group clamps the workpiece, the driving wrench is pulled upward to move. When the driving wrench moves upward, it drives the driving wheel provided on the driving wrench to move in the opposite direction in the driving groove, and then presses the driving wheel on the driving top column provided on the reset driving plate. When the driving wheel is pressed on the driving top column, the center of the driving wheel is in a straight line. Therefore, the driving top column is pressed by the driving wheel and cannot move upward to reset, while the upward movement of the driving top column The force of the driving wheel is resisted and cannot be moved. The force of the interaction between the driving top column and the driving wheel enables the driving top column and the driving wheel to be fixed, thereby completing the work clamping work. This structure is simple and effective, and does not require the help of other mechanisms to complete the work clamping and fixing. It not only saves costs but also is easy to operate. When it is necessary to loosen the workpiece, only a little downward force is needed on the driving wrench, and the straight line formed between the center of the driving top column and the driving wheel will be destroyed, thereby causing the driving top column to overcome the pressure of the driving wheel and move upward. At the same time, during the clamping process, the movement of the driving wheel will stretch the driving spring. When the straight line between the center of the driving top column and the driving wheel is destroyed, the driving wheel is reset by the elastic force of the driving spring, thereby releasing the workpiece. The operation is simple and effective.

[0011] Furthermore, the driving slot includes a top column limiting slot, a wrench driving slot and a spring slot, the top column limiting slot is arranged at the lower end of the wrench driving slot, the driving top column is located in the top column limiting slot, and a spring slot is provided at the upper end of the wrench driving slot, one end of the driving spring is fixed on the inner wall of the spring slot, a spring connecting portion is provided on one side of the wrench driving portion, and the other end of the driving spring is fixed on the spring connecting portion; a roller is provided on the other end of the driving wrench.

[0012] With the above arrangement, when the reset drive plate moves downward, the driving column arranged on the reset drive plate moves synchronously downward into the column limit slot. When the driving column has completed its movement, the driving wrench is pulled upward to cause the driving wheel to move in the wrench driving slot and press the driving column, thereby completing the fixation. The operation is simple and effective.

[0013] Furthermore, the reset assembly also includes a reset spring, a buffer spring, a buffer baffle and a reset connecting rod. A spring connecting seat is provided on the reset drive plate. One end of the reset spring is fixed on the spring connecting seat. A reset connecting rod is provided at the other end of the reset spring. A buffer baffle is provided on the bottom end of the base. The reset connecting rod passes through the buffer baffle and is connected to the clamp group. A buffer spring is provided between the reset connecting rod and the buffer baffle.

[0014] With the above arrangement, when the reset drive plate moves downward, the reset spring and the buffer spring move downward and are compressed. During electroplating operation, the reset spring and the buffer spring are in a compressed state. When the drive assembly is loosened and fixed, the reset drive plate is driven to move upward by the rebound action of the reset spring, thereby loosening the fixation. The structure is simple and effective.

[0015] Furthermore, the clamp group includes a fixed clamping plate, a movable clamping plate and a clamping plate limiting assembly, one end of the fixed clamping plate is fixed to the bottom end of the base, and a fixed clamping arm is provided on the other end of the fixed clamping plate, the movable clamping plate includes a movable connecting plate and a movable clamping arm, the movable connecting plate is connected to the reset connecting rod, the movable connecting plate is connected to the fixed clamping plate through the clamping plate limiting assembly, and a movable clamping arm is provided at the bottom end of the movable connecting plate, the movable clamping arm and the fixed clamping arm are distributed up and down, and a clamping portion is formed at the bottom end of the movable clamping arm and the top end of the fixed clamping arm; with the above arrangement, the workpiece is located in the clamping portion, and when clamping, the reset driving plate drives the reset assembly to move downward and then drives the movable clamping plate to move downward to clamp the workpiece.

[0016] Furthermore, a guide block is provided on one end of the fixed clamping arm and the movable clamping arm located at the clamping portion, and the guide block is a triangular protrusion with an inclined surface on one side facing the clamping portion; thus, the workpiece can be more conveniently entered into the clamping portion through the action of the guide block.

[0017] Furthermore, the splint limiting assembly includes a splint limiting connecting column, a splint limiting block and a splint sliding block. A splint connecting groove arranged along the length direction of the movable connecting plate is provided on the movable connecting plate, and the splint sliding block is arranged in the splint connecting groove. The splint sliding block is fixed to the fixed splint through the splint limiting connecting column, and a splint limiting block is provided on the splint sliding block, and the splint limiting block is in contact with the movable splint; thus, through the action of the splint limiting assembly, the movable splint is limited to moving up and down on the fixed splint only along the length direction of the fixed splint and can also prevent the movable splint from separating from the fixed splint.

[0018] Furthermore, the outer surfaces of the fixed splint and the movable splint are covered with an insulating layer. Thus, the setting of the insulating layer ensures that the fixed splint and the movable splint are not prone to leakage during the electroplating process of the workpiece.

[0019] Furthermore, a plating block is provided at the bottom end of the movable clamping arm and the top end of the fixed clamping arm.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 4 As shown, a fixture for electroplating equipment includes an electroplating fixture, which is disposed on a circular guide rail (not shown) of fully automatic electroplating equipment. The electroplating fixture includes a base 1, a drive mechanism 2 disposed on the base 1, and a fixture group 3. The drive mechanism 2 is disposed at the upper end of one side of the base 1, and the fixture group 3 is disposed at the lower end of one side of the base 1. The drive mechanism 2 is connected to the fixture group 3. In this embodiment, the electroplating fixture is moved on the circular guide rail by a motor and performs electroplating. The specific electroplating process is conventional and will not be described in detail below.

[0028] The driving mechanism 2 includes a driving component 4 and a reset component 5. The driving component 4 is arranged at the top of the base 1. The reset component 5 is connected to the clamp group 3. The reset component 5 is arranged on one side of the base 1. The driving component 4 is arranged above the reset component 5. The reset component 5 includes a reset driving plate 51. The reset driving plate 51 is arranged on one side of the base 1 and connected to the driving component 4. The reset driving plate 51 is connected to the clamp group 3.

[0029] like Figure 2 As shown, the drive assembly 4 includes a drive mounting plate 41, a drive wrench 42, a drive spring 43, a wrench connecting column 44, a drive top column 45, a drive shaft 46 and a drive wheel 47. A drive groove 48 is provided on the drive mounting plate 41, which passes through the two end surfaces of the drive mounting plate 41. A reset drive plate 51 is provided on the front end surface of the drive mounting plate 41. A drive top column 45 is provided on the reset drive plate 51 located in the drive groove 48. The drive wrench 42 is arranged on the rear end surface of the drive mounting plate 41 through the wrench connecting column 44. A wrench driving part 421 is provided on one end of the drive wrench 42. The wrench driving part 421 extends to the drive groove 48. One side of the wrench driving part 421 is connected to the side wall of the drive groove 48 through the drive spring 43. A drive shaft 46 is provided on the end of the wrench driving part 421 away from the drive wrench 42. A drive wheel 47 is provided on the drive shaft 46. The drive wheel 47 is located in the drive groove 48 and is connected to the drive top column 45. The driving slot 48 includes a top column limiting slot 481, a wrench driving slot 482 and a spring slot 483. The top column limiting slot 481 is set at the lower end of the wrench driving slot 482, and the driving top column 45 is located in the top column limiting slot 481. A spring slot 483 is provided at the upper end of the wrench driving slot 482. One end of the driving spring 43 is fixed to the inner wall of the spring slot 483. A spring connecting portion 422 is provided on one side of the wrench driving portion 421, and the other end of the driving spring 43 is fixed to the spring connecting portion 422. A roller 424 is provided on the other end of the driving wrench 42 (at Figure 1 shown in ).

[0030] With the above arrangement, when the reset drive plate 51 moves downward, the driving top column 45 provided on the reset drive plate 51 moves synchronously downward into the top column limiting groove 481. When the driving top column 45 has completed its movement, the driving wrench 42 is pulled upward so that the driving wheel 47 moves in the wrench driving groove 482 to press the driving top column 45, thereby completing the fixation. The operation is simple and effective.

[0031] like Figure 1As shown, the reset assembly 5 further includes a reset spring 52, a buffer spring 53, a buffer baffle 54, and a reset connecting rod 55. A spring connecting seat 521 is provided on the reset drive plate 51. One end of the reset spring 52 is fixed to the spring connecting seat 521. A reset connecting rod 55 is provided at the other end of the reset spring 52. A buffer baffle 54 is provided at the bottom end of the base 1. The reset connecting rod 55 passes through the buffer baffle 54 and connects to the clamp assembly 3. A buffer spring 53 is provided between the reset connecting rod 55 and the buffer baffle 54. In this embodiment, the elastic force of the reset spring is greater than the elastic force of the drive spring.

[0032] With the above arrangement, when the reset drive plate 51 moves downward, the reset spring 52 and the buffer spring 53 move downward and are compressed. During electroplating operation, the reset spring 52 and the buffer spring 53 are in a compressed state. When the drive assembly 4 is loosened and fixed, the rebound action of the reset spring 52 drives the reset drive plate 51 to move upward, thereby loosening the fixation. The structure is simple and effective.

[0033] like Figure 1 and Figure 3 When the workpiece is clamped, the reset drive plate 51 drives the reset plate 32 to move upwards, and the reset drive plate 51 drives the reset plate 32 to move downwards to clamp the workpiece.

[0034] like Figure 1 As shown, a guide block 341 is provided on one end of the fixed clamping arm 311 and the movable clamping arm 322 located at the clamping portion 34, and the guide block 341 is a triangular protrusion with an inclined surface on one side facing the clamping portion 34; thus, the guide block 341 can make it easier for the workpiece to enter the clamping portion 34.

[0035] like Figure 3When the cam 331 is in the unlock state, the locking cam 332 is locked and the locking cam 333 is locked, so the cam 332 can be unlocked when the cam 331 is unlocked.

[0036] The outer surfaces of the fixed clamping plate 31 and the movable clamping plate 32 are covered with an insulating layer (not shown in the figure). Therefore, the setting of the insulating layer ensures that the fixed clamping plate and the movable clamping plate are not prone to leakage during the electroplating process of the workpiece.

[0037] like Figure 3 As shown, a plating block 35 is provided on the bottom end of the movable clamping arm 322 and the top end of the fixed clamping arm 311. The plating block 35 passes through the insulating layer to connect the movable clamping arm 322 and the fixed clamping arm 311. The arrangement of the plating block and the insulating layer can ensure that the electroplating effect will not be weakened, and also ensure that the electroplating fixture will not have leakage problems.

[0038] like Figure 1 As shown, one or more limiting ridges 11 are provided on one side of the base 1, and the reset drive plate 51 is restrictedly connected between the limiting ridges 11 and the base 1. Through the setting of the limiting ridges 11, the reset drive plate 51 is restricted to move only along the up and down directions of the base 1 on the base 1 and can prevent the reset drive plate 51 from detaching from the base 1.

[0039] like Figure 4As shown, a sliding wheel group 6 is provided on the other side of the base 1, and the sliding wheel group 6 includes an upper pulley 61, a lower pulley 62 and a side pulley 63. A pulley upper end plate 64 is provided on the top of the other side of the base 1, and a pulley lower end plate 65 is provided on the bottom end of the other side of the base 1. The upper pulley 61 is provided at the end of the pulley upper end plate 64 close to the base 1, and the lower pulley 62 is provided at the end of the pulley lower end plate 65 close to the base 1. Side pulleys 63 are provided at the end of the pulley upper end plate 64 away from the base 1 and the end of the pulley lower end plate 65 away from the base 1. A side pulley 63 is also provided on the base 1 between the upper end plate 64 of the pulley and the lower end plate 65 of the pulley; a track groove 66 is formed between the upper pulley 61, the lower pulley 62 and the side pulley 63, and the annular guide rail is located in the track groove 66 and is rollingly connected to the upper pulley 61, the lower pulley 62 and the side pulley 63. Thus, when installing the electroplating fixture, the installation can be completed by inserting the track groove into the annular guide rail. The operation process is simple and convenient. When the electroplating fixture moves, the upper pulley, the lower pulley and the side pulley slide on the upper and lower end surfaces and the side surfaces of the annular guide rail.

[0040] In the above structure, the electroplating fixture moves along the annular guide rail to perform electroplating work, and the clamp group 3 is driven by the driving component 4 to clamp the workpiece. During work, the clamping part 34 moves along the annular guide rail for clamping work, and the electroplating block 35 performs electroplating on the workpiece during the movement; when clamping, the reset driving plate 51 is manually pulled downward to make the clamping part 34 clamp the workpiece. After the clamping part 34 clamps the workpiece, the driving wrench 42 is pulled upward to move. When the driving wrench 42 moves upward, it drives the driving wheel 47 provided on the driving wrench 42 to move in the opposite direction in the driving groove 48, and then presses the driving wheel 47 to press the driving top column 45 provided on the reset driving plate 51. When the driving wheel 47 is pressed on the driving top column 45, the center of the driving top column 45 and the driving wheel 47 is in a straight line. Therefore, the driving top column 45 is pressed by the driving wheel 47 and cannot move upward to reset, while the driving top column The upward force of 45 resists the driving wheel 47 from moving, and the driving push column 45 and the driving wheel 47 are fixed together by the force of the interaction between the driving push column 45 and the driving wheel 47, thereby completing the work clamping work. This structure is simple and effective, and does not require the help of other mechanisms to complete the clamping and fixing of the work, which not only saves costs but also is convenient to operate. When it is necessary to loosen the workpiece, only a little downward force is needed on the driving wrench 42, and the straight line formed between the driving push column 45 and the center of the driving wheel 47 will be destroyed, thereby causing the driving push column 45 to overcome the pressure of the driving wheel 47 and move upward. At the same time, during the clamping process, the movement of the driving wheel 47 will stretch the driving spring 43. When the straight line between the driving push column 45 and the center of the driving wheel 47 is broken, the elastic rebound action of the driving spring 43 drives the driving wheel 47 to reset, thereby releasing the workpiece. The operation is simple and effective.
