Description

Technical Field

[0001] This utility model relates to the field of circuit board processing equipment technology, and in particular to a circuit board processing fixture. Background Technology

[0002] Circuit board (PCB) processing fixtures are key tooling in electronics manufacturing, primarily used for the precise fixing and support of PCB boards. Existing PCB processing fixtures generally use two clamping plates to hold the edges of the PCB. Such fixtures are only suitable for PCBs of uniform thickness that are not yet fitted with any components. There are also suction-type fixtures, but these are prone to damaging the PCB and are unsuitable for holding larger, heavier PCBs.

[0003] Therefore, it is necessary to develop a circuit board processing fixture to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to design a circuit board processing fixture to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions: Circuit board processing fixtures, including: Upper clamping component; The lower clamping assembly has the same structure as the upper clamping assembly. Both the upper and lower clamping assemblies include a hydraulic cylinder. The hydraulic cylinder has a first cavity and multiple parallel second cavities. The first end of each of the multiple second cavities is connected to one side of the first cavity. A piston is slidably installed in each second cavity. The piston is connected to the first end of a clamping rod. The second end of the clamping rod extends out of the second end of the second cavity and is connected to a chuck. The first cavity is connected to the first output end of a power element of a hydraulic system. The multiple second cavities are connected to each other and then connected to the second output end of the power element of the hydraulic system. The chucks of the upper clamping assembly and the lower clamping assembly are arranged opposite each other. Mounting plate; the hydraulic cylinder of the upper clamping assembly is fixedly mounted on the upper first side of the mounting plate, and the hydraulic cylinder of the lower clamping assembly is fixedly mounted on the lower first side of the mounting plate.

[0006] The beneficial effects of this utility model are as follows: In this application, the upper clamping assembly and the lower clamping assembly use multiple clamps to clamp one edge of the circuit board. Since the clamping action is performed by multiple clamps, these clamps can be adapted to act on multiple uneven surfaces on both sides of the circuit board. Due to the hydraulic system, each clamp exerts the same force on the circuit board, preventing uneven force on the circuit board from causing damage. Attached Figure Description

[0016] like Figure 1-3 As shown, the circuit board processing fixture includes: Upper clamp component 9; The lower clamping assembly 10 and the upper clamping assembly 9 have the same structure. Both the upper clamping assembly 9 and the lower clamping assembly 10 include a hydraulic cylinder 11. The hydraulic cylinder 11 has a first cavity 12 and multiple parallel second cavities 14. The first ends of the multiple second cavities 14 are connected to one side of the first cavity 12. A piston 16 is slidably installed in each second cavity 14. The piston 16 is connected to the first end of the clamping rod 17. The second end of the clamping rod 17 extends out of the second end of the second cavity 14 and is connected to a chuck 18. The first cavity 12 is connected to the first output end of a power element of a hydraulic system. The multiple second cavities 14 are connected and then connected to the second output end of the power element of the hydraulic system. The chucks 18 of the upper clamping assembly 9 and the lower clamping assembly 10 are arranged opposite each other. Mounting plate 8; the hydraulic cylinder 11 of the upper clamping assembly 9 is fixedly installed on the upper first side of the mounting plate 8, and the hydraulic cylinder 11 of the lower clamping assembly 10 is fixedly installed on the lower first side of the mounting plate 8.

[0017] like Figure 1 As shown, the circuit board processing fixture also includes an adjuster for multi-dimensional attitude adjustment of the mounting plate 8. The first end of the adjuster is fixedly installed, and the second end of the adjuster is connected to the second side of the mounting plate 8.

[0018] like Figure 1As shown, the regulator includes a first motor 1, a first electric telescopic rod 3, a first connecting seat 4, a second connecting seat 5, a second motor 6, a second electric telescopic rod 7, and a third motor. The first motor 1 is fixedly positioned, and its shaft is connected to the first end of the first electric telescopic rod 3. The second end of the first electric telescopic rod 3 is connected to the first connecting seat 4. The third motor is installed in the second connecting seat 5, and its shaft is connected to the first connecting seat 4. The second motor 6 is installed on the second connecting seat 5, and its shaft is connected to the first end of the second electric telescopic rod 7. The second end of the second electric telescopic rod 7 is connected to the second side of the mounting plate 8.

[0019] like Figure 1 As shown, the regulator also includes a rotating seat 2, the first end of which is mounted on the first end of the first electric telescopic rod 3, and the shaft of the first motor 1 is connected to the second end of the rotating seat 2.

[0020] like Figure 1 As shown, the shaft of the first motor 1 is perpendicular to the shaft of the third motor, and the shaft of the third motor is perpendicular to the shaft of the second motor 6.

[0021] like Figure 3 As shown, a first hydraulic pipe 13 and a second hydraulic pipe 15 are also installed on the side wall of the hydraulic cylinder 11. The first hydraulic pipe 13 is connected to the first cavity 12, and the second hydraulic pipe 15 is connected to multiple second cavities 14.

[0022] like Figure 4 As shown, the multiple second cavities 14 are arranged in a rectangular array. The clamps 18 arranged in a rectangular array can evenly transmit clamping force to all parts of the circuit board, avoiding damage to the circuit board due to uneven force.

[0023] The chuck 18 includes a rigid chuck 18 and a flexible chuck 18 (not shown in the figure). The first end of the rigid chuck 18 is connected to the second end of the clamping rod 17, and the flexible chuck 18 is fitted over the second end of the rigid chuck 18. Using the flexible chuck 18 can prevent damage to the circuit board.

[0024] Working principle: During operation, the first motor 1 rotates its shaft, causing the rotating seat 2 to rotate in the first plane. The rotating seat 2 drives the first electric telescopic rod 3 to rotate, which in turn drives the first connecting seat 4 to rotate. The first electric telescopic rod 3 can adjust the length position of the first connecting seat 4 and its subsequent connecting components. Then, the rotation of the third motor shaft drives the second connecting seat 5 and its subsequent connecting components to rotate in the second plane. The rotation of the second motor 6 drives the second electric telescopic rod 7, the mounting plate 8 connected to the second electric telescopic rod 7, and its subsequent connecting components to rotate in the third plane. Finally, the positions of the upper clamping assembly 9 and the lower clamping assembly 10 are adjusted. The circuit board is positioned so that it is centered between the upper clamping assembly 9 and the lower clamping assembly 10. Then, the hydraulic system supplies oil into the first cavity 12 through the first hydraulic pipe 13 and supplies oil out through the second hydraulic pipe 15, pushing the piston 16 to move outward. This ultimately moves the clamping rod 17 and the clamping heads 18 until some of the clamping heads 18 first press against the higher parts of the circuit board, and then continues to apply pressure until the remaining clamping heads 18 press against the lower parts of the circuit board. During this process, the clamping heads 18 at the higher parts will not move due to the reaction force, and the pressure will be evenly distributed to all parts of the circuit board through multiple pressure heads, preventing damage to the circuit board at the higher parts. The combined action of the upper clamping assembly 9 and the lower clamping assembly 10 completes the clamping of the upper and lower surfaces of the circuit board. When it is necessary to remove the circuit board, only the hydraulic system needs to be activated in a specific direction. The first electric telescopic rod 3 and the second electric telescopic rod 7 work together to completely detach the upper clamping assembly 9 and the lower clamping assembly 10 from the circuit board. The remaining motors work together to control the flipping or other postures of the circuit board.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
