Modern EPS motors generally use flexible circuit boards to realize the electrical connection between the motor stator and the external controller. Printed circuit boards (PCBAs) are used to carry flexible board connectors, which need to complete multiple processes such as welding, testing, and assembly on the production line.

[0003] Currently, on PCBA processing and testing production lines, when it is necessary to operate or assemble the front and back sides, it is unavoidable to flip them. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an automatic flipping device for flexible board connection PCBA, which can conveniently and quickly realize the automatic flipping of PCBA boards.

[0005] To achieve the above technical objectives, this application provides the following technical solution: a flexible board connection PCBA flipping device, comprising, The conveying unit includes a conveyor line and a transfer tray that slides on the conveyor line. An auxiliary positioning flip plate for placing PCBA boards is placed on the transfer tray. The PCBA boards are conveyed to the designated workstation through the conveying unit. The flipping unit includes two flipping fixtures arranged opposite each other, with a flipping station between them. The conveying unit transports the PCBA board to the flipping station. The flipping fixture includes a base with a clamping mechanism slidably connected to it. The two clamping mechanisms move towards each other or away from each other to clamp or release the auxiliary positioning plate. The opposing surfaces of the clamping mechanisms are provided with arc-shaped track grooves. The synchronous belt pulley mechanism consists of two sets, each connected to one of the two clamping mechanisms, and the two sets of synchronous belt pulley mechanisms are arranged in opposite directions. The drive transmission unit includes a servo motor mounted on one side, which transmits the motor output to the drive shaft via a coupling. The drive shaft is connected to two synchronous pulley mechanisms in sequence along its axial direction. The flip block moves along the arc-shaped track groove path; one end of the flip block is connected to the drive shaft, and the other end is fixed to the auxiliary positioning flip plate. When the drive shaft rotates, it drives the flip block to move along the arc-shaped track groove and drives the auxiliary plate to flip 180°, and the PCBA board also flips 180° accordingly.

[0006] According to this utility model, the surface of the clamping mechanism is provided with two concentric arc-shaped track grooves with different radii, namely a first arc-shaped track groove and a second arc-shaped track groove, and the flipping block moves along the path of one of the arc-shaped track grooves with a smaller radius.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] like Figure 3As shown, this application embodiment provides a flexible board connection PCBA flipping device, including a conveying section and a flipping section. The conveying section includes a conveyor line 100, a transfer tray 110 that slides on the conveyor line 100, an auxiliary positioning flip plate 200 placed on the transfer tray 110, and the PCBA board placed on the auxiliary positioning flip plate 200. The PCBA board is conveyed to a designated workstation through the transfer tray 110, where it is stopped by a stopper. A lifting mechanism fixed on a platform directly below the tray lifts and positions the board. The conveyor line 100 is equipped with a double-speed chain conveyor, and a stopper component is provided at the far end for stopping the transfer tray 110. The position of the stopper component corresponds to the flipping workstation of the flipping section. The lifting component positions and lifts the transfer tray 140, and the flipping device flips the auxiliary positioning flip plate 200 on the transfer tray 110, thereby simultaneously achieving the PCBA flipping into place.

[0013] like Figure 1 and Figure 2 As shown, the flipping unit includes two flipping fixtures 300 arranged opposite each other, with a flipping station between them. The conveying unit transports the PCBA board to this station. The flipping fixture 300 includes a base 310, on which a clamping mechanism 320 is slidably connected. The clamping mechanism 320 is driven by a cylinder 330 to slide on the base 310, which can make the two clamping mechanisms 320 move towards each other or away from each other, thereby clamping or releasing the auxiliary positioning plate 200.

[0014] This utility model fixes the PCBA to be flipped by a clamping mechanism 320, and the two clamping mechanisms 320 are driven by cylinders 330 on both sides to move towards each other to clamp the auxiliary positioning plate 200.

[0015] It also includes a servo motor 400 mounted on one side, which smoothly transmits its output to the ball spline shaft 420 via a coupling 410, and then transmits the motion to the synchronous pulley mechanisms 500 mounted on opposite sides of the two clamping mechanisms 320. When the servo motor 400 is turned on, its output drives the ball spline shaft 420 to rotate via a reduction motor, which in turn drives the synchronous pulley mechanism 500 to move, thus improving the rotation stability of the flipping block 600, which will be detailed below. The two cylinders 300 respectively push the left and right sides of the clamping mechanism 320 to move towards each other, and the clamping mechanism 320 moves along the linear guide rail 311 mounted on the base 310 to ensure movement accuracy.

[0016] The clamping mechanism 320 has two concentric arc-shaped track grooves 321 and 322 with different radii on its opposing surfaces. It also includes a flipping block 600 that moves along the path of one of the arc-shaped track grooves with a smaller radius. One end of the flipping block 600 is connected to the drive shaft, and the positioning sleeve 610 is connected to the flipping block 600. The two positioning sleeves 610 are arranged opposite to each other and are used to position the auxiliary positioning plate 200. Correspondingly, the auxiliary positioning plate 200 is provided with a positioning post 142 that matches the positioning sleeve 610. The positioning post 142 is connected to the positioning sleeve 610 to achieve positioning. The flipping block 600 is used to drive the auxiliary positioning flipping plate 200 to move. The flipping block 600 moves along the path of the corresponding arc-shaped track groove through the rotation of the synchronous belt pulley mechanism 500 and the ball spline shaft 420.

[0017] In this embodiment of the application, an adjustment block and an idler wheel may be added to adjust the tension of the synchronous belt pulley mechanism 500.

[0018] Working principle: such as Figure 1 , Figure 2 , Figure 4a and Figure 4b As shown, the PCBA board to be flipped is transferred to its position via the transfer tray 110, stopped, lifted and positioned. The cylinder 330 pushes the corresponding clamping mechanism 320 to move towards each other on the left and right sides respectively. After it is in position, the auxiliary positioning flip plate 200 to be flipped is clamped between the two flipping blocks 600. At the same time, the positioning post 142 on the side of the auxiliary positioning plate 200 enters the positioning sleeve 610 of the flipping assembly. Then, the servo motor 400 is turned on and drives the ball spline shaft 420 to rotate through the coupling 410 connected to the output shaft of the reducer. The ball spline shaft 420 drives the pulley transmission mechanism 500 to rotate. Since one ball spline shaft 420 drives the pulley transmission mechanisms 500 on both sides to rotate at the same time, it can ensure that the movement trajectory of the pulley transmission mechanisms 500 on both sides is synchronized. And the flipping block 600 and the flipping assembly opposite it start to move and flip along the arc-shaped track groove path synchronously and stably. After it is in position, the servo motor 400 stops. At this time, the flexible board connected PCBA is flipped and assembled in place.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
