[0019] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0020] Combined with the attached Figures 1-5 , a processing and folding device for PCB boards, including an equipment main body 1. A support side plate 2 is connected to the rear side of the equipment main body 1. Electrically driven front and rear assembly lines 3 and 4 are connected to both ends of the front side of the support side plate 2. The styles of the front assembly line 3 and the rear assembly line 4 are not limited to those in the attached drawings and can be configured according to the style of the PCB board. A rotating disc 5 located between the front assembly line 3 and the rear assembly line 4 is rotatably connected to the front side of the support side plate 2 in an electrically driven manner. A bottom support plate 6 is connected to the bottom of the front side of the rotating disc 5. During actual use, the upper surface of the bottom support plate 6 should be slightly lower than the front assembly line 3 and the rear assembly line 4, so as to accurately fold the PCB board. After the rotating disc 5 rotates, the lower surface of the bottom support plate 6 will be slightly higher than the rear assembly line 4, so as to accurately convey and fold the PCB board. An adjustment groove 8 is provided at the top of the bottom support plate 6 on the front side of the rotating disc 5. An electrically driven adjustment screw 9 is connected in the adjustment groove 8. A sliding block 10 threadedly connected to the adjustment screw 9 is connected in the adjustment groove 8 in a limited sliding manner. The sliding block 10 is connected to a lifting support plate 11. Infrared sensors 23 are connected to both sides of the top of the bottom support plate 6 and both sides of the bottom of the lifting support plate 11. That is, the front assembly line 3 transports the PCB board. When the PCB board enters between the bottom support plate 6 and the lifting support plate 11, the infrared sensor 23 will sense the entry of the PCB board. After reaching the position, the sliding block 10 and the lifting support plate 11 are driven to descend by the rotation of the adjustment screw 9 to clamp the PCB board. Then, through the rotation of the rotating disc 5, the rotation of the PCB board can be driven for flipping.

The plurality of driving rotating rollers 7 extend into the gear transmission box 13 and are connected with a gear transmission group 15. The gear transmission group 15 needs to ensure that the plurality of driving rotating rollers 7 rotate in the same direction. After the PCB board is flipped by the above structure, the gear transmission box 13 and the first motor 14 drive the plurality of driving rotating rollers 7 to rotate. Cooperating with the plurality of driven rotating rollers 12, the PCB board can be driven to be conveyed above the rear assembly line 4. Then the rotating disc 5 rotates and resets again. By repeating the operation, the production of PCB boards in an assembly line manner can be achieved.

[0022] A second motor 16 for driving the rotation of the adjusting screw rod 9 is connected to the inner top of the rotating disc 5. A third motor 21 for driving the rotation of the rotating disc 5 is connected to the rear side of the support side plate 2. A fourth motor 22 for driving the front assembly line 3 and the rear assembly line 4 is connected to the rear side of the support side plate 2. Through direct connection of the motors, the driving operation of the electrical components in the driving device can be carried out.

[0023] Limit sliding grooves 17 are arranged on both sides of the adjusting groove 8 of the rotating disc 5. A first limit slider 18 for cooperating with the limit sliding grooves 17 is connected to the rear side of the lifting support plate 11. A limit ring groove 19 for cooperating with the rotating disc 5 is arranged inside the support side plate 2. A second limit slider 20 for cooperating with the limit ring groove 19 is connected to the outer side of the rotating disc 5. By setting the limit structure, the rotation and lifting structures can be conveniently and stably driven for operation.

[0024] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the purpose of the creation of the present invention, they shall fall within the protection scope of the present invention.
