Description

Technical Field

[0001] The invention relates to the technical field of electroplating, and in particular to a PCB board electroplating hanging plate fixture. Background Art

[0002] In the PCB manufacturing process, the electroplating process is very important for improving the conductivity and corrosion resistance of the circuit board. In the PCB electroplating process, the PCB board needs to be fixed and moved by the electroplating hanging plate fixture. The Chinese patent application with application number 202011604333.7 discloses "a gantry line PCB board electroplating hanging plate fixture, belonging to the field of printed circuit board technology, including a workbench and a centering component and a clamping component arranged on the workbench, the centering component is arranged on the top of the workbench, and the clamping component is provided with two groups, and the two groups of clamping components are respectively arranged on the top of the workbench and are in The left and right sides of the centering component include a centering base plate, a first centering rod, a second centering rod, a centering cross bar and a centering column. When working, the PCB board is placed on the top of the centering base plate and between the two centering columns. At this time, the first centering rod is pushed backward, so that the rectangle formed by the first centering rod, the second centering rod and the two centering cross bars is gradually deformed into a parallelogram, so that the distance between the first centering rod and the second centering rod is gradually reduced, so that the PCB board is clamped by the first centering rod and the second centering rod, and then the two centering columns are used to limit the position to achieve the centering of the PCB board". This technical solution only solves the problem that the hanging plate clamp in the prior art cannot automatically center the PCB circuit board, resulting in the need for manual centering every time the hanging plate clamp clamps the PCB circuit board, which increases the work intensity of the operator. In the prior art, when the PCB board hanging plate clamp is in use, the operator is usually required to pull the clamp down one by one with force to fix the PCB board, which is not only labor-intensive but also affects the production efficiency of the PCB board.

When the airbag 509 is inflated, it expands and drives the movable cylinder 206 to extend outward from the corner clamping cylinder 203 and the side clamping cylinder 205, so that the PCB board is clamped. According to the thickness of the PCB board obtained by detection, the inflation amount in the airbag 509 is controlled to adjust the clamping pressure to avoid damage to the PCB board due to excessive clamping pressure of the clamp.

[0020] Working principle: When the present invention is in use, several groups of hanging plate clamps can be sleeved on the hanging rod 1, and the connecting seat 201 can be fixed after sliding. The spacing of the clamps can be adjusted according to the width of the PCB board in actual production. After the adjustment is completed, the PCB board is inserted upward from between the two side clamping cylinders 205 at the bottom. When the PCB board contacts the detection wheel 403, the detection wheel 403 is squeezed to drive the detection rod 402 to move toward the direction close to the fixed frame 401, and the sliding resistor 406 is driven to move by the detection rod 402. At this time, the detection device 408 detects the moving distance of the sliding resistor 406 through the conductive plate 407 to obtain the thickness of the PCB board, and sends a control signal through the detection device 408, and then the top two corners of the PCB board After contacting the positioning plate 208, the corners thereof are aligned to complete the positioning of the PCB board. When the control end receives the signal from the detection device 408, the air supply end is controlled to supply air, and air is supplied to the control valve 502 through the air supply pipe 503. The first air guide pipe 504 is controlled to be turned on through the control valve 502, and air is supplied to the second air pipe 506 through the fixed joint 505, and then air is supplied to the third air pipe 508 through the rotary joint 507, so that the airbag 509 is inflated. When the airbag 509 is inflated, it expands and drives the movable cylinder 206 to extend outward from the corner clamping cylinder 203 and the side clamping cylinder 205, so that the PCB board is clamped. According to the thickness of the PCB board obtained by the detection, the inflation amount in the airbag 509 is controlled to adjust the clamping pressure to avoid damage to the PCB board caused by excessive clamping pressure of the clamp. When the electroplating is completed, the connecting rod 204 is pulled upward to rotate the rotating frame 202, and the locking block 301 is driven to be inserted into the locking groove 303 through the rotating frame 202. At this time, the locking motor 310 is controlled to start, and the synchronization rod 309 is driven to rotate through the locking motor 310, and the first gear 307 is driven to rotate through the synchronization rod 309, and the second gear 308 is driven to rotate through the first gear 307. When the second gear 308 rotates, it drives the tooth plate 306 to move downward. At this time, the lifting plate 305 is used to make the insertion rod 304 follow the tooth plate 306 and descend at the same time. After the insertion rod 304 descends, it is inserted into the insertion hole 302, so that the rotating frame 202 is fixed, and the clamp is unfolded. In production, there is no need to frequently adjust the distance between the two sets of clamps. When a PCB board with a large width needs to be clamped, the clamp in the middle can be unfolded, which not only avoids the operator from operating the clamps one by one, but also makes the device applicable to PCB boards of different sizes, effectively improving the production efficiency of PCB boards.
