Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, and particularly to an impedance device for circuit board production. Background Art

[0002] A circuit board is a basic platform for supporting and connecting electronic components. It is usually made of non-conductive insulating materials, such as glass fiber-reinforced epoxy resin (FR-4), as the substrate, and covered with a thin copper foil layer.

[0003] On the circuit board, through drilling and etching processes, part of the copper foil is removed to form various-shaped wires, pads, and other metal connections required for electronic components. These connections connect signals, power, and ground wires in the circuit through a wire network to achieve circuit functions.

[0004] When the circuit board is subjected to impedance detection, it needs to be clamped and limited by a clamping device before impedance detection. However, clamping is likely to cause damage to the circuit board, affecting the use of the circuit board. Content of the Utility Model

[0005] The purpose of the utility model is to provide an impedance device for circuit board production, which has the advantages of being convenient for limiting the circuit board, preventing damage to the circuit board caused by clamping, and at the same time being able to rotate the circuit board to a suitable angle for impedance detection according to needs, and solves the problem that the circuit board is clamped and limited by a clamping device before impedance detection, but clamping is likely to cause damage to the circuit board, affecting the use of the circuit board.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An impedance device for circuit board production, including a workbench, a moving plate, a motor, and a connecting block. One side of the upper surface of the workbench is fixed with a fixing plate. One side of the fixing plate is rotatably connected to a rotating shaft. One side of the rotating shaft is fixed with a turntable. One side of the turntable is provided with a slot. One side of the upper surface of the turntable is provided with a long slot. The connecting block is inserted into the long slot. The upper surface of the connecting block is fixed with a moving plate.

[0007] Preferably, four columns are fixed on the lower surface of the workbench in a rectangular array. The workbench can be supported by the four columns, making the overall device stable.

[0008] Preferably, a control switch box is fixed at the front end of the workbench. A display screen and buttons are installed on the front end of the control switch box from top to bottom in sequence. The start and stop of the motor and the motor can be controlled through the control switch box.

[0009] Preferably, a threaded hole is provided at the front end of the connecting block, and a second round hole is provided at the front end of the turntable. A motor is fixed to the front end of the turntable. The rear end of the transmission shaft of the motor extends into the second round hole. A threaded rod is fixed to the rear end of the transmission shaft of the motor. The rear end of the threaded rod penetrates through the threaded hole and is threadedly connected. By fixing the threaded rod through the transmission shaft of the motor, power is provided for the rotation of the threaded rod, enabling the connecting block and the moving plate to move as needed, facilitating the limitation of the circuit board inserted into the slot.

[0010] Preferably, the width of the long groove provided on one side of the upper surface of the turntable matches the width of the connecting block. By matching the width of the long groove with the width of the connecting block, the long groove can limit the connecting block, preventing the threaded rod from rotating and the connecting block from rotating accordingly, facilitating the movement of the connecting block.

[0011] Preferably, a first round hole is provided on the other side of the fixing plate, and a motor is fixed to the other side of the fixing plate. One side of the transmission shaft of the motor extends into the first round hole, and a rotating shaft is fixed to one side of the transmission shaft of the motor. By fixing the rotating shaft through the transmission shaft of the motor, power is provided for the rotation of the rotating shaft and the turntable. At the same time, the circuit board inserted into the slot can be rotated as needed, facilitating the impedance detection of different positions of the circuit board.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, the rotating shaft is rotatably connected to one side of the fixing plate, the turntable is fixed to one side of the rotating shaft, a slot is provided on one side of the turntable, a long groove is provided on one side of the upper surface of the turntable, the connecting block is inserted into the long groove, and the moving plate is fixed to the upper surface of the connecting block. When impedance detection needs to be performed on the circuit board, one side of the circuit board is inserted into the slot, and then the motor is started to rotate the threaded rod, enabling the connecting block and the moving plate to move as needed, so that the moving plate can move above the slot. Then the motor is started again to rotate the turntable and the circuit board to a suitable angle as needed for impedance detection, achieving the effects of facilitating the limitation of the circuit board, preventing damage to the circuit board caused by clamping, and at the same time being able to rotate the circuit board to a suitable angle for impedance detection as needed.

Specific implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 4 , an embodiment provided by the present invention: A circuit board production impedance device, including a workbench 2, a moving plate 9, a motor 10 and a connecting block 15. One side of the upper surface of the workbench 2 is fixed with a fixed plate 4, and four support pillars 1 arranged in a rectangular array are fixed on the lower surface of the workbench 2. The front end of the workbench 2 is fixed with a control switch box 6. A display screen and buttons are installed on the front end of the control switch box 6 in sequence from top to bottom. The workbench 2 can be supported by the four support pillars 1, so that the whole device is stably placed. The start and stop of the motor 5 and the motor 10 can be controlled through the control switch box 6.

[0021] One side of the fixed plate 4 is rotatably connected to a rotating shaft 7. A first round hole 8 is opened on the other side of the fixed plate 4. A motor 5 is fixed on the other side of the fixed plate 4. One side of the transmission shaft of the motor 5 extends into the first round hole 8. One side of the transmission shaft of the motor 5 is fixed with a rotating shaft 7. The rotating shaft 7 is fixed by the transmission shaft of the motor 5, providing power for the rotation of the rotating shaft 7 and the turntable 3. At the same time, the circuit board inserted into the slot 11 can be rotated as needed, facilitating impedance detection at different positions of the circuit board. One side of the rotating shaft 7 is fixed with a turntable 3.

[0022] A slot 11 is provided on one side of the turntable 3, and a long slot 12 is provided on one side of the upper surface of the turntable 3. The width of the long slot 12 provided on one side of the upper surface of the turntable 3 matches the width of the connecting block 15. By the matching of the width of the long slot 12 and the width of the connecting block 15, the long slot 12 can limit the connecting block 15 to prevent the threaded rod 13 from rotating and the connecting block 15 from following the rotation, facilitating the movement of the connecting block 15. The connecting block 15 is inserted into the long slot 12. A threaded hole 14 is provided at the front end of the connecting block 15, and a second round hole 16 is provided at the front end of the turntable 3. A motor 10 is fixed to the front end of the turntable 3. The rear end of the transmission shaft of the motor 10 extends into the second round hole 16. A threaded rod 13 is fixed to the rear end of the transmission shaft of the motor 10. The rear end of the threaded rod 13 passes through the threaded hole 14 and is threadedly connected. By fixing the threaded rod 13 to the transmission shaft of the motor 10, power is provided for the rotation of the threaded rod 13, enabling the connecting block 15 and the moving plate 9 to move as needed, facilitating the limitation of the circuit board inserted into the slot 11 and preventing damage to the circuit board caused by clamping. A moving plate 9 is fixed to the upper surface of the connecting block 15.

[0023] When impedance detection of the circuit board is required, the circuit board is inserted into the slot 11 provided on the turntable 3. Then, the control switch box 6 is operated to start the motor 10, causing the threaded rod 13 to rotate. The connecting block 15 and the moving plate 9 can move as needed, enabling the moving plate 9 to move above the slot 11. Then, the control switch box 6 is operated to start the motor 5, allowing the rotating shaft 7 and the turntable 3 to rotate as needed. At the same time, the circuit board can be rotated to a suitable angle as needed, and then impedance detection of the circuit board is performed. The effect of facilitating the limitation of the circuit board, preventing damage to the circuit board caused by clamping, and at the same time being able to rotate the circuit board to a suitable angle for impedance detection as needed is achieved.
