Description

Technical Field

[0001] The present invention belongs to the technical field of electroplating fixtures, and particularly relates to a combined fixture for an electroplating system and a working method thereof. Background Art

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

[0003] A circuit board electroplating fixture is a tool used to hang and fix a circuit board during electroplating to ensure its correct position and posture. Using a fixture for electroplating the circuit board can ensure that the coating is evenly deposited on the surface of the circuit board, and at the same time conduct current to ensure the electroplating quality and efficiency.

[0004] The patent application with the patent publication number CN216427466U discloses a PCB circuit board electroplating fixture. By synchronously driving several driving gears to rotate through a driving shaft, the synchronous opening or synchronous clamping of the movable clamping plates can be realized, and the operation is convenient without separately opening several movable clamping plates. Although this fixture can clamp and fix the circuit board, the sizes of circuit boards are diverse. In actual use, this fixture cannot clamp the circuit board at the maximum width of the circuit board, and cannot ensure the stability of the circuit board. Moreover, this fixture cannot clamp the lower part of the circuit board, resulting in the situation that the circuit board shakes or even bends during electroplating in the electroplating tank, unable to ensure the stability of the circuit board and the electroplating quality at the same time.

The telescopic rods 51 are used to adjust the position of the lifting rod 62.

[0064] The two groups of telescopic rods 51 are arranged staggeredly. By this setting method, it is avoided that the two groups of telescopic rods 51 contact and the position of the telescopic rods 51 cannot be adjusted.

[0065] Above the side of the second fixture fixing plate 5 close to the reinforcing steel plate 34, there is a hanger adjusting plate 52 connected. The hanger adjusting plate 52 is used to assist in adjusting the position of the telescopic rod 51.

[0077] A third fixture fixing plate 8 is connected to the position near the middle of the hanging tool support square pipe 1 below the lifting rod 62. A second fixture assembly is connected to one side of the third fixture fixing plate 8 close to the lifting rod 62. The second fixture assembly is used for clamping and fixing the positions of the two lower corners of the circuit board 9, thereby improving the stability of the circuit board 9.

[0078] The second fixture assembly includes a second fixture base 81 which is connected to the third fixture fixing plate 8. In the middle of one side of the second fixture base 81 away from the third fixture fixing plate 8, a second clamping plate 82 is rotatably connected.

[0081] On the side of the first fixture fixing plate 14 away from the middle fixing plate 3, corresponding to the position of the rear fixing plate 31, symmetrically arranged front fixing plates 4 are provided. On the side of each front fixing plate 4 close to the first fixture fixing plate 14, three groups of symmetrically arranged fixing rods 41 are connected. The fixing rods 41 are connected to the reinforcing steel plate 34.

[0084] Multiple uniformly arranged spring grooves 43 are provided at the positions of the chute grooves 42 between the front fixing plates 4, the first fixture fixing plate 14 and the middle fixing plate 3. A plurality of second springs 44 are connected between the front fixing plates 4 and the middle fixing plates 3. The second springs 44 are located in the spring grooves 43. The second springs 44 are used to reset the front fixing plates 4 to make the rear fixing plate 31 close to the middle fixing plate 3, thereby clamping and fixing the telescopic rods 51.

[0085] Below the fixture support square pipe 1, an opening and closing air cylinder 55, a guide rod lifting air cylinder 56, and a clamping air cylinder 57 are respectively arranged. The opening and closing air cylinder 55 corresponds to the front fixing plate 4, the guide rod lifting air cylinder 56 corresponds to the pressure rod 71, and the clamping air cylinder 57 corresponds to the first clamping plate 21 and the second clamping plate 82. The opening and closing air cylinder 55 is used to push the front fixing plate 4 to move the rear fixing plate 31 away from the middle fixing plate 3. The guide rod lifting air cylinder 56 is used to simultaneously squeeze two corresponding pressure rods 71 to disengage the tooth 65 from the tooth claw 74. The clamping air cylinder 57 is used to push the first clamping plate 21 and the second clamping plate 82 to move 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.

[0086] Working principle: Before clamping and fixing the circuit board 9, it is necessary to adjust the height of the second fixture 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 fixture assembly connected to the second fixture fixing plate 5. When adjusting, first start the guide rod lifting air cylinder 56 to make the guide rod lifting air cylinder 56 squeeze two corresponding pressure rods 71, and synchronously squeeze four groups of pressure rods 71 to move the pressure rods 71 away from the lifting rod 62, so that the tooth 65 is disengaged from the tooth claw 74, thus making the lifting rod 62 lose its fixation. At this time, the height of the lifting rod 62 and the second fixture assembly can be adjusted. With the cooperation of the second fixture assembly, the lower part of the circuit board 9 can be clamped, ensuring the stability of the circuit board 9, thus ensuring the electroplating quality of the circuit board 9. And with the cooperation of the lifting rod 62, the circuit board 9 can be clamped and fixed according to the size of the circuit board 9, so that the circuit board 9 with different heights can be clamped and fixed, improving the adaptability.

[0087] After the height adjustment of the second fixture 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 restoring force of the third spring 73, the pressure rod 71 will reset, causing the tooth 65 to mesh with the tooth claw 74 again, thereby fixing the lifting rod 62. After the height adjustment of the second fixture assembly is completed, the opening and closing cylinder 55 is started to push the front fixing plate 4. After the front fixing plate 4 is pushed, it will push the rear fixing plate 31 with the cooperation of the fixing rod 41, causing the rear fixing plate 31 to move 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 jaw cylinder 53 is started to clamp the four hanger adjusting plates 52 simultaneously. After the hanger adjusting plates 52 are clamped, the movable electric cylinder 54 is started to move the corresponding two groups of telescopic rods 51 synchronously to positions closer to or farther from each other, thereby adjusting the position of the telescopic rod 51. After the position adjustment of the telescopic rod 51 is completed, the horizontal positions of the first fixture assembly and the second fixture assembly connected to the second fixture fixing plate 5 are adjusted. With the cooperation of the opening and closing cylinder 55, the jaw cylinder 53, and the movable electric cylinder 54, the positions of the first fixture assembly and the second fixture assembly connected to the second fixture fixing plate 5 can be adjusted, so that the four corners of the circuit board 9 can be clamped and fixed on the maximum width of the circuit board 9, improving the stability of the circuit board 9 and preventing the circuit board 9 from shaking or even bending during electroplating, ensuring the electroplating quality;

[0088] After the position adjustment of the telescopic rod 51, the movable electric cylinder 54 is started again to move the movable electric cylinder 54 away from the front fixing plate 4. Under the restoring force of the second spring 44, the front fixing plate 4 will reset. After the front fixing plate 4 resets, with the cooperation of the fixing rod 41, it will drive the rear fixing plate 31 to reset synchronously, causing the rear fixing plate 31 to approach the middle fixing plate 3, thereby fixing the telescopic rod 51 again. After the position adjustment of the second fixture assembly and the first fixture assembly connected to the second fixture fixing plate 5, the unclamping cylinder 57 is started to squeeze all the first fixture assemblies and the second fixture assemblies synchronously, creating a gap between the first fixture assembly and the second fixture assembly. At this time, a manipulator is used to insert the circuit board 9 into the gap between the first fixture assembly and the second fixture assembly. After insertion, the unclamping cylinder 57 is started again to move the unclamping cylinder 57 away from the first fixture assembly and the second fixture assembly, causing the first fixture assembly to reset under the restoring force of the first spring 22 and the second fixture assembly to reset under the restoring force of the fourth spring 83. After the first fixture assembly and the second fixture assembly are reset, the circuit board 9 can be clamped and fixed. Using a manipulator for feeding instead of manual feeding reduces manpower and improves efficiency at the same time.

[0089] A working method of a combined hanger for an electroplating system includes the following steps:

[0090] S1: Start the guide rod lifting cylinder 56 to make the guide rod lifting cylinder 56 squeeze the corresponding two pressure rods 71, and synchronously squeeze the four groups of pressure rods 71 to adjust the height of the lifting rod 62 and the second fixture assembly.

[0091] S2: Start the guide rod lifting cylinder 56 again to make the guide rod lifting cylinder 56 move away from the pressure rod 71 to fix the lifting rod 62.
