Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production, in particular to a turnover device for circuit board production. Background Art

[0002] During the manual soldering process of a circuit board, operations need to be performed on both sides in sequence. That is, after the front side of the circuit board is processed, the circuit board needs to be turned over and its back side needs to be processed. However, since the circuit board needs to be clamped by a tooling during processing to maintain the stable force of the circuit board and prevent phenomena such as solder joint misalignment caused by the movement of the circuit board, this also brings inconvenience to the turnover of the circuit board. The staff needs to first disassemble the circuit board, then turn it over and install it, which not only increases the workload of the staff but also reduces the work efficiency. Therefore, it is necessary to provide a new turnover device for circuit board production to solve the above technical problems. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a turnover device for circuit board production, which can be adjusted and clamped according to the specifications of the circuit board to be processed, has strong overall adaptability, and can control the relative angle between the support bar and the circuit board and the horizontal plane by manipulating the driving rod, facilitating the rapid turnover processing of a batch of circuit boards and can be adjusted according to the operating position of the staff, improving work efficiency.

[0004] The turnover device for circuit board production provided by the utility model includes a mounting frame and a support frame rotatably mounted inside the mounting frame at both ends through a shaft rod. A driving rod is also rotatably provided on the mounting frame. A worm is provided on the outer wall of the driving rod, and the worm and the worm gear provided on the shaft rod form a worm and worm gear transmission mechanism.

[0005] Two guiding plates of equal height and parallel to the driving rod are fixedly provided inside the support frame, and two support bars symmetrically distributed relative to the shaft rod are slidably arranged on the two guiding plates.

[0006] During use, the staff can control the turnover of the support bar and the circuit board on the support bar relative to the horizontal plane by rotating the driving rod, and at the same time use the self-locking characteristics of the worm gear and the worm to fix the rotation angle of the current circuit board, so that the staff can adjust according to their own operating habits and positions, and improve work efficiency.

[0007] Preferably, a rotating rod parallel to the driving rod is rotatably connected to the inner wall of the support frame at both ends, and screw threads with opposite helix directions are provided at both ends of the rotating rod and are respectively screwed with screw holes preset on the corresponding support bars.

[0008] Since the rotating rod is screwed to the two support bars through threaded sections with opposite helix directions respectively, the turnover of the rotating rod can drive the two support bars to move relatively or away from each other on the guide plate, so as to complete the adjustment of the distance between the two support bars and adapt to the circuit boards with corresponding size specifications.

[0009] Preferably, communication installation grooves and open grooves are formed on the relative side walls of the two support bars. The top of the open groove communicates with the outside world. A limiting bar is arranged in the installation groove. The top of the limiting bar is assembled with the bottom of the adjusting rod through a bearing. The top of the adjusting rod penetrates through the installation groove to the outside world and is screwed to a preset screw hole on the top wall of the installation groove through a preset thread.

[0010] Workers can place several circuit boards into the open groove and push them horizontally into the installation groove in sequence to complete the placement of multiple circuit boards of the same specification. Then, by controlling the rotation of the adjusting rod, the limiting bar can be driven to move vertically inside the installation groove to press the side of the circuit board.

[0011] Preferably, a guide rod is arranged on the top surface of the limiting bar on one side of the adjusting rod. A scale bar is arranged on the outer wall of the guide rod and penetrates through the installation groove to the outside world. The guide rod can guide the movement of the limiting bar and accurately adjust the displacement of the limiting bar through its own scale bar, preventing the limiting bar from pressing the circuit board excessively and damaging the circuit board.

[0012] Preferably, an electric cylinder is arranged on the guide plate near the open groove. The output end of the electric cylinder is arranged towards the installation groove and is connected with a pressing plate. A pressure sensor is arranged on the end face of the pressing plate.

[0013] Preferably, a controller is arranged on the outer wall of the mounting rack. The input end of the controller is in signal connection with the output end of the pressure sensor, and the output end of the controller is in signal connection with the control chip of the electric cylinder.

[0014] The electric cylinder can push the pressing plate to push multiple circuit boards placed in the open groove into the installation groove in sequence. By setting the pressure sensor, the controller can monitor the pressure state between the pressing plate and the circuit board in real time through the pressure sensor. When the pressure value reaches the set range, the work of the electric cylinder can be automatically stopped, thus avoiding the phenomenon that the pressing plate presses the circuit board excessively.

[0015] Compared with the related technology, the circuit board production turnover device provided by the present utility model has the following beneficial effects: The present utility model can perform adjustable clamping according to the specifications of the circuit boards to be processed, with strong overall adaptability. And the relative angle between the support bars and the circuit board and the horizontal plane can be controlled by manipulating the driving rod, which is convenient for the rapid turnover processing of batch circuit boards and can adjust the angle according to the operating position of the workers, improving work efficiency.

[0020] The following describes the specific implementation of the present utility model in detail with specific embodiments.

[0021] Please refer to Figures 1 to 3 , a flipping device for circuit board production, including a mounting frame 1 and a support frame 21 rotatably mounted at both ends inside the mounting frame 1 through a shaft rod. A driving rod 22 is also rotatably provided on the mounting frame 1. A worm 221 is provided on the outer wall of the driving rod 22, and the worm 221 and a worm gear 222 provided on the shaft rod form a worm and worm gear transmission mechanism;

[0022] Two guiding plates 33 of equal height and parallel to the driving rod 22 are fixedly provided inside the support frame 21. Two support bars 3 symmetrically distributed relative to the shaft rod are slidably arranged on the two guiding plates 33. Communication installation grooves 31 and open grooves 32 are provided on the opposite side walls of the two support bars 3. The top of the open groove 32 communicates with the outside. A limit bar 4 is arranged inside the installation groove 31. The top of the limit bar 4 is assembled with the bottom of the adjusting rod 41 through a bearing. The top of the adjusting rod 41 penetrates through the installation groove 31 to the outside and is screwed with a screw hole preset on the top wall of the installation groove 31 through a preset thread. A guiding rod 42 is provided on one side of the adjusting rod 41 on the top surface of the limit bar 4. A scale bar is provided on the outer wall of the guiding rod 42 and penetrates through the installation groove 31 to the outside.

[0023] An electric cylinder 35 is provided on the guiding plate 33 near the open groove 32. The output end of the electric cylinder 35 is arranged towards the installation groove 31 and is connected with a pressing plate 36. A pressure sensor 351 is provided on the end face of the pressing plate 36. A controller 11 is provided on the outer wall of the mounting frame 1. The input end of the controller 11 is in signal connection with the output end of the pressure sensor 351, and the output end of the controller 11 is in signal connection with the control chip of the electric cylinder 35.
