Description

Technical Field

[0001] The present application relates to the technical field of clamping devices, and in particular to a clamping device for a circuit board. Background Art

[0002] During the processing of cutting, engraving or drilling of circuit boards, a clamping device is needed to fix the circuit board to ensure processing accuracy and safety. However, the existing clamping device can usually only clamp the two sides of the circuit board. Since this clamping method only clamps the two sides of the circuit board, the circuit board is easily impacted by external forces during the processing and the position is shifted, which affects the processing accuracy. Utility Model Content

[0003] The problem to be solved by the present application is that the existing circuit board clamping device can only clamp two side surfaces of the circuit board, which makes it easy to be impacted by external forces and cause position deviation during the processing.

[0004] In order to solve the above technical problems, the present application provides a clamping device for a circuit board, including a frame plate for serving as a basic support, wherein the interior of the frame plate is symmetrically arranged with clamping components for clamping the corners of the circuit board with adjustable spacing, and the clamping components can also serve as a support for the bottom surface of the circuit board.

[0005] Since the clamping device of the present application is designed with a clamping component, the clamping component can stably clamp multiple corners of the circuit board and effectively prevent the circuit board from positional displacement, thereby solving the problem that the circuit board clamping device of the prior art can only clamp the two sides of the circuit board, which makes it easy to be impacted by external forces and cause positional displacement during the processing.

[0012] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0013] The present application relates to a clamping device for a circuit board, such as Figure 1-5 As shown, the clamping device includes a frame plate 2 for serving as a basic support, and the frame plate 2 has symmetrically arranged clamping components 1 for clamping the corners of the circuit board with adjustable spacing. In order to prevent the circuit board from falling due to external force impact during the clamping process, the clamping component 1 can also support the bottom surface of the circuit board.

[0014] The clamping assembly 1 includes a transverse clamp 3 and a longitudinal clamp 4. The transverse clamp 3 is arranged on the upper part of the frame plate 2, and the transverse clamping distance is adjusted according to the width of the circuit board. The longitudinal clamp 4 is arranged on the upper part of the transverse clamp 3, and the longitudinal clamping distance is adjusted according to the thickness of the circuit board.

[0015] The transverse clamp 3 includes a first cylinder 5, a transverse clamp bar 7, and a clamping bar 6. The first cylinder 5 is arranged at the midline position of the normal direction on one side of the frame plate 2. The end of the first cylinder 5 is arranged with a transverse clamp bar 7 which is driven by the first cylinder 5 to change the clamping spacing. In order to be able to clamp and fix the circuit board more stably, clamping bars 6 for clamping the corners of the circuit board are symmetrically arranged at both ends of the transverse clamp bar 7. In order to adapt to circuit boards of various lengths, the clamping bar 6 and the transverse clamp bar 7 are connected by bolts or pins that can be easily disassembled, so that the corner clamping and limiting operations of circuit boards of various lengths can be performed by changing the connection position of the clamping bar 6 on the upper part of the transverse clamp bar 7.

[0016] The longitudinal clamp 4 includes a second cylinder 9, a longitudinal clamp bar 10, and a longitudinal pressure bar 8. The second cylinder 9 is symmetrically arranged on both sides of the first cylinder 5 and connected to the transverse clamp bar 7. The lower end of the second cylinder 9 is provided with a longitudinal clamp bar 10 connected to it and driven by it to perform a lifting operation, so that the second cylinder 9 drives the longitudinal clamp bar 10 to be lifted and lowered to support the lower surface of the circuit board. In order to be able to adapt to the longitudinal clamp bar 10, longitudinal pressure bars 8 for abutting the upper surface of the circuit board are symmetrically and spaced on one side of the transverse clamp bar 7 along its width direction. With the help of the cooperation between the longitudinal clamp bar 10 and the longitudinal pressure bar 8, the circuit board can be clamped and limited in the vertical direction.

[0017] When in use, firstly, the first cylinder 5 drives the transverse clamping bar 7 to adjust the transverse spacing so that the transverse spacing is adapted to the width of the circuit board. Secondly, by changing the position of the clamping bar 6 on the upper part of the transverse clamping bar 7, the spacing between the clamping bars 6 is adapted to the length of the circuit board. Again, the second cylinder 9 drives the longitudinal clamping bar 10 to adjust the longitudinal spacing so that the spacing between the longitudinal clamping bar 10 and the longitudinal pressure bar 8 is adapted to the thickness of the circuit board. In this way, the stable clamping and limiting operation of the circuit board can be achieved, and there will be no positional displacement even if the circuit board is engraved or drilled.
