Detailed Implementation

[0020] This utility model is as follows Figures 1 to 4 As shown, a circuit board precision positioning and fixing device includes a mounting base 10, a lifting drive device 20, a positioning arm 30, a clamping arm 40, and a feeding plate 50 for placing the circuit board, wherein:

[0021] The feeding plate 50 is disposed on the upper side of the mounting base 10. The lifting drive device 20 is vertically disposed on the mounting base 10. The middle part of the positioning arm 30 is hinged to the mounting base 10. The lower end of the positioning arm 30 is movably abutted against the output end of the lifting drive device 20. The upper end of the positioning arm 30 is movably abutted against the side wall of the circuit board. The lower end of the clamping arm 40 is hinged to the output end of the lifting drive device 20. The upper end of the clamping arm 40 is movably clamped to the upper surface of the circuit board.

[0022] The circuit board is placed on the feeding plate 50. When the circuit board needs to be positioned and fixed, the output end of the lifting drive device 20 descends, the lower end of the positioning arm 30 descends with the middle of the positioning arm 30 as the center, and the upper end of the positioning arm 30 moves towards the side wall of the circuit board with the middle of the positioning arm 30 as the center. The positioning arm 30 positions the side wall of the circuit board, and the upper end of the clamping arm 40 descends and clamps the upper surface of the circuit board. When the circuit board needs to be removed from the feeding plate 50, the output end of the lifting drive device 20 rises, and the upper ends of the positioning arm 30 and the clamping arm 40 move away from the circuit board, releasing the positioning and fixing of the circuit board.

[0023] The circuit board is positioned and secured by employing a lifting drive device 20, a positioning arm 30, and a clamping arm 40, preventing the circuit board from shifting position and meeting the requirements for circuit board positioning and fixation. The positioning arm 30 can accurately position the circuit board laterally, ensuring the positional accuracy of the circuit board during installation or processing. The clamping arm 40 fixes the upper surface of the circuit board, ensuring the stability of the circuit board. The lifting drive device 20 provides a driving function for positioning and clamping the circuit board, saving energy. The overall structure is compact and occupies little space.

[0024] The upper end of the positioning arm 30 is equipped with a positioning member 31, which is movable and abuts against the side wall of the circuit board; the upper end of the clamping arm 40 is equipped with a clamping member 41, which is movable and clamped to the upper surface of the circuit board.

[0025] The positioning arm 30 is L-shaped, and the positioning member 31 is movably installed on the upper end of the positioning arm 30; the clamping arm 40 is bent, and the clamping member 41 is movably installed on the upper end of the clamping arm 40. The front end of the positioning member 31 and the front end of the clamping member 41 are both elastic.

[0026] Both the positioning element 31 and the clamping element 41 can be clamping blocks; by movably installing the positioning element 31 on the upper end of the positioning arm 30 and movably installing the clamping element 41 on the upper end of the clamping arm 40, it is convenient to adjust the position of the positioning element 31 and the clamping element 41, which is convenient to adapt to circuit boards of different sizes and specifications, and has a wide range of applications.

[0027] A spring 51 is vertically arranged between the feeding plate 50 and the positioning arm 30 to drive the positioning member 31 to press against the side wall of the circuit board. The upper end of the spring 51 is connected to the lower surface of the feeding plate 50, and the lower end of the spring 51 is connected to the lower side of the positioning arm 30. The use of the spring 51 facilitates the use of elastic force to drive the positioning member 31 to press against the side wall of the circuit board.

[0028] The lower end of the positioning arm 30 is vertically movable and equipped with an abutment rod 32. The lower end of the abutment rod 32 is detachably abutted against the output end of the lifting drive device 20. The detachable abutment between the positioning arm 30 and the output end of the lifting drive device 20 is achieved by using the abutment rod 32.

[0029] The clamping arm 40 has an arc-shaped guide groove 42, and the mounting base 10 is provided with a guide rod 43 corresponding to the guide groove 42. The clamping arm 40 is movably clamped to the upper surface of the circuit board through the guide groove 42 and the guide rod 43.

[0030] The position guidance of the clamping arm 40 during its movement is achieved by using guide groove 42 and guide rod 43.

[0031] The lifting drive device 20 includes a lifting drive cylinder 21 and a lifting slide 22. The lifting drive cylinder 21 is mounted on the mounting base 10, and the lifting slide 22 is mounted on the shaft end of the lifting drive cylinder 21. The lifting slide 22 serves as the output end of the lifting drive device 20. The lifting drive cylinder 21 drives the lifting slide 22 to move up and down.

[0032] The usage method and principle of the circuit board precision positioning and fixing device are as follows:

[0033] The circuit board is placed on the feeding plate. When the circuit board needs to be positioned and fixed, the output end of the lifting drive device descends, the lower end of the positioning arm descends with the middle of the positioning arm as the center, and the upper end of the positioning arm moves towards the side wall of the circuit board with the middle of the positioning arm as the center. The positioning arm positions the side wall of the circuit board, and the upper end of the clamping arm descends and clamps the upper surface of the circuit board. When the circuit board needs to be removed from the feeding plate, the output end of the lifting drive device rises, and the upper ends of the positioning arm and the clamping arm move away from the circuit board, releasing the positioning and fixing of the circuit board.

[0034] The key design feature of this invention is that it uses a lifting drive device, a positioning arm, and a clamping arm to position and clamp the circuit board, preventing the circuit board from shifting and meeting the requirements for circuit board positioning and fixing. The positioning arm can accurately position the circuit board laterally, ensuring the positional accuracy of the circuit board during installation or processing. The clamping arm fixes the upper surface of the circuit board, ensuring the stability of the circuit board. The lifting drive device provides a driving force for positioning and clamping the circuit board, saving energy. The overall structure is compact and occupies little space.

[0035] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
