Description

Technical Field

[0002] PCB electroplating is a process of depositing a metal layer on the surface of a circuit board through electrolysis. In this process, the circuit board acts as the cathode, the metal anode dissolves under the action of the electrolyte, and the metal ions are deposited on the surface of the circuit board under the action of the electric field, forming a uniform metal coating.

[0003] The PCB plating hanger is a tool used to hang and fix the PCB during the electroplating process to ensure its correct position and posture. Using the hanger to electroplate the PCB can ensure that the coating is evenly deposited on the surface of the PCB, while conducting current to ensure the quality and efficiency of electroplating.

[0050] A plurality of evenly arranged teeth 65 are provided on the limiting plane 63 away from the second fixture fixing plate 5 , and the teeth 65 are used to assist in fixing the position of the lifting rod 62 .

[0051] The side of the sleeve 6 away from the second fixture fixing plate 5 is connected to a support 7 , and the side of the support 7 away from the sleeve 6 is rotatably connected to a symmetrically arranged pressure rod 71 , which is used to fix the position of the lifting rod 62 .

The opening and closing cylinder 55 corresponds to the front fixed plate 4, the guide rod lifting cylinder 56 corresponds to the pressure rod 71, and the opening and clamping cylinder 57 corresponds to the first clamping plate 21 and the second clamping plate 82. The opening and closing cylinder 55 is used to push the front fixed plate 4 to make the rear fixed plate 31 away from the middle fixed plate 3, the guide rod lifting cylinder 56 is used to squeeze the two corresponding pressure rods 71 ​​at the same time to make the teeth 65 lose engagement with the claws 74, and the opening and clamping cylinder 57 is used to push the first clamping plate 21 and the second clamping plate 82 to make the lower end of the first clamping plate 21 away from the first clamping seat 2, and the upper end of the second clamping plate 82 away from the second clamping seat 81.

[0064] Working principle: before clamping and fixing the circuit board 9, it is necessary to adjust the height of the second clamp assembly according to the size of the circuit board 9, and at the same time, it is necessary to adjust the horizontal position of the first clamp assembly connected to the second clamp fixing plate 5. When adjusting, first start the guide rod lifting cylinder 56 to make the guide rod lifting cylinder 56 squeeze the corresponding two pressure rods 71, and simultaneously squeeze the four groups of pressure rods 71, so that the pressure rods 71 ​​are away from the lifting rods 62, so that the teeth 65 and the claws 74 lose engagement, so that the lifting rods 62 lose fixation, and at this time, the height of the lifting rods 62 and the second clamp assembly can be adjusted. Through the cooperation of the second clamp assembly, the bottom of the circuit board 9 can be clamped, which can ensure the stability of the circuit board 9, thereby ensuring the electroplating quality of the circuit board 9, and with the cooperation of the lifting rods 62, the circuit board 9 can be clamped and fixed according to the size of the circuit board 9, so that circuit boards 9 of different heights can be clamped and fixed, thereby improving adaptability; After the height adjustment of the second clamp assembly is completed, the guide rod lifting cylinder 56 is started again to move the guide rod lifting cylinder 56 away from the pressure rod 71. Under the action of the restoring force of the third spring 73, the pressure rod 71 will be reset to make the teeth 65 mesh with the claws 74 again, so that the lifting rod 62 is fixed. After the height adjustment of the second clamp assembly is completed, the opening and closing cylinder 55 is started again to push the front fixing plate 4. After the front fixing plate 4 is pushed, the rear fixing plate 31 will be pushed with the cooperation of the fixing rod 41 to move the rear fixing plate 31 away from the middle fixing plate 3. After the rear fixing plate 31 moves away from the middle fixing plate 3, the telescopic rod 51 loses its fixation. At this time, the clamping claw cylinder 53 is started to clamp the four hanger adjustment plates 52 at the same time. After the hanger adjustment plates 52 are clamped, the activity is started again. The movable electric cylinder 54 makes the two corresponding groups of telescopic rods 51 move synchronously to positions close to or away from each other, thereby adjusting the positions of the telescopic rods 51. After the position adjustment of the telescopic rods 51 is completed, the horizontal positions of the first clamp assembly and the second clamp assembly connected to the second clamp fixing plate 5 are adjusted. With the cooperation of the opening and closing cylinder 55, the clamping claw cylinder 53 and the movable electric cylinder 54, the positions of the first clamp assembly and the second clamp assembly connected to the second clamp fixing plate 5 can be adjusted, so that the four corners of the circuit board 9 can be clamped and fixed at the maximum width of the circuit board 9, which can improve the stability of the circuit board 9. When the circuit board 9 is electroplated, the circuit board 9 will not shake or even bend, and the electroplating quality can be guaranteed. After the position of the telescopic rod 51 is adjusted, the movable electric cylinder 54 is started again to move the movable electric cylinder 54 away from the front fixing plate 4. Under the action of the restoring force of the second spring 44, the front fixing plate 4 will be reset. After the front fixing plate 4 is reset, with the cooperation of the fixing rod 41, the rear fixing plate 31 will be driven to reset synchronously, so that the rear fixing plate 31 is close to the middle fixing plate 3, so that the telescopic rod 51 is fixed again. After the position of the second clamp assembly and the first clamp assembly connected to the second clamp fixing plate 5 is adjusted, the clamping cylinder 57 is started to squeeze all the first clamp assemblies and the second clamp assemblies synchronously. A gap is generated between the first clamp assembly and the second clamp assembly. At this time, a manipulator is used to insert the circuit board 9 into the gap between the first clamp assembly and the second clamp assembly. After insertion, the clamping cylinder 57 is started again to move the clamping cylinder 57 away from the first clamp assembly and the second clamp assembly, so that the first clamp assembly is reset under the action of the restoring force of the first spring 22, and the second clamp assembly is reset under the action of the restoring force of the fourth spring 83. After the first clamp assembly and the second clamp assembly are reset, the circuit board 9 can be clamped and fixed, and the manipulator is used to load the material instead of manual loading, which can reduce manpower and improve efficiency.

[0065] A working method of a combined hanger for an electroplating system comprises the following steps: S1: Start the guide rod lifting cylinder 56 to squeeze the corresponding two pressure rods 71 ​​and simultaneously squeeze the four groups of pressure rods 71 ​​to adjust the height of the lifting rod 62 and the second clamp assembly.

[0066] S2: Start the guide rod lifting cylinder 56 again to move the guide rod lifting cylinder 56 away from the pressure rod 71, so that the lifting rod 62 is fixed.

[0067] S3: Start the opening and closing cylinder 55, so that the opening and closing cylinder 55 pushes the front fixing plate 4, so that the telescopic rod 51 loses its fixation.

[0068] S4: Start the clamping claw cylinder 53 to clamp the four hanger adjustment plates 52 at the same time.

[0069] S5: Start the movable electric cylinder 54 to make the two corresponding groups of telescopic rods 51 move synchronously to positions close to or away from each other, thereby adjusting the positions of the telescopic rods 51, that is, adjusting the horizontal position of the first clamp assembly connected to the second clamp fixing plate 5.

[0070] S6: Start the movable electric cylinder 54 again, so that the movable electric cylinder 54 is away from the front fixed plate 4, so that the telescopic rod 51 is fixed again.

[0071] S7: Start the clamping cylinder 57 so that the clamping cylinder 57 squeezes all the first clamp components and the second clamp components synchronously, so that a gap is generated between the first clamp components and the second clamp components.

[0072] S8: Use a robot to insert the circuit board 9 into the gap between the first clamp component and the second clamp component.
