At this time, the rotating knob can be driven to rotate by rotating the rotating shaft. When the rotating shaft stops rotating, the limit block is released so that the No. 1 spring drives the limit block to reset and snaps into the slot to limit the rotating shaft.

The movement of the pressure rod will contact the piston block so that the piston block moves toward the inside of the cylinder. Because of the vacuum setting inside the cylinder, the push rod moves upward until it contacts the PCB circuit board, causing the PCB circuit board to tilt and slide into the discharge plate.

[0013] According to the above technical solution, the output device also includes a fixed plate, a discharge plate, a second rotary motor, a rotating shaft, a chain belt, a push block, a push plate and a No. 6 spring.

When the PCB circuit board contacts the discharge plate, the discharge plate moves downward and compresses the No. 6 spring at the same time, so as to buffer the falling of the PCB circuit board and prevent the PCB circuit board from being damaged by collision when it falls. The rotation of the second rotary motor drives the rotating shaft to rotate in coordination with the chain belt, the push block, the push plate and the fixed plate so that the PCB circuit board is transported to the next processing place, thereby realizing the automation of PCB circuit board processing.

[0014] The present invention provides a flipping device for PCB circuit board processing, which has the following beneficial effects: (1) The invention, through the setting of the flipping device, presses the limit block and compresses the No. 1 spring at the same time to make the limit block disengage from the slot. At this time, the rotating shaft can be rotated to drive the rotating knob to rotate. When the rotating shaft stops rotating, the limit block is released so that the No. 1 spring drives the limit block to reset and engage in the slot to limit the rotating shaft, thereby preventing the rotating shaft from rotating due to accidental touch of external force and avoiding unnecessary losses. The rotation of the rotating knob drives the rotating rod to rotate left and right and resets the rotating rod through the No. 1 torsion spring. The rotating rod rotates to cooperate with the receiving block, the sliding rod and the connecting block to achieve the effect of adjusting the left and right position of the placement block 1, that is, it can be adjusted in time according to the size of different PCB circuit boards. Through rapid adjustment, the operator can flip and process the PCB circuit board more efficiently. The output end of the electric push rod 1 and the output end of the electric push rod 2 rise simultaneously to drive the slide block and the installation block to move. When it moves to the maximum distance, the rotating motor 1 rotates 180° to drive the placement block 2 to rotate, thereby achieving flipping.

[0015] (2) The invention, through the setting of the clamping device, places the PCB circuit board on the top of the placement block 1 and the placement block 2, and clamps the PCB circuit board by rotating the turntable to drive the screw rod to rotate in coordination with the spiral groove, the clamping block, the trigger rod, the penetration rod and the pressure plate. After the clamping is completed, the PCB circuit board is rotated by rotating the placement block 2. When the clamping force is too large, the pressure plate is squeezed and moves upward. The pressure plate moves to compress the second spring and drives the penetration rod to move in coordination with the trigger rod, the clamping block and the clamping groove to achieve the anti-clamping function, which can effectively prevent the clamping device from causing scratches, dents or other mechanical damage to the surface of the PCB circuit board during the clamping process. When the turntable is rotated, the slider is pulled out to make the slider disengage from the limit groove. Only then can the turntable be rotated to prevent external force from accidentally touching the turntable and causing clamping operation errors.

[0016] (3) The invention, through the setting of the output device, drives the pressure rod to rotate by the rotation of the clamping block, and releases the clamping device after the PCB circuit board is flipped 180 degrees. At this time, the clamping block moves downward to cooperate with the pressure rod, piston block, cylinder and push rod to contact the PCB circuit board, so that the PCB circuit board is tilted and slides into the discharge plate. When the PCB circuit board contacts the discharge plate, the discharge plate moves downward and compresses the No. 6 spring at the same time, so as to buffer the falling of the PCB circuit board and prevent the PCB circuit board from being damaged by collision when it falls. The rotating shaft is driven by the rotation of the rotating motor 2 to cooperate with the chain belt, push block, push plate and fixed plate to transport the PCB circuit board to the next processing place, so as to realize the automation of PCB circuit board processing and reduce the difficulty of operation for the staff.

[0027] The output device includes a cylinder 30, a piston block 31 and a push rod 32. The cylinder 30 is fixedly installed on the top of the base 1, the piston block 31 is slidably installed on the inner wall of the cylinder 30, and the push rod 32 is slidably installed on the inner wall of the cylinder 30. The interior of the cylinder 30 is set to be a vacuum. A No. 4 spring is arranged between the piston block 31 and the cylinder 30, and the piston block 31 is reset by the arranged No. 4 spring.

[0029] When the present embodiment is working, the PCB circuit board is placed on the top of the placement block 111 and the placement block 2 115. After the clamping is completed, the rotation of the placement block 2 115 drives the PCB circuit board to rotate, the rotation of the PCB circuit board drives the placement block 111 to rotate, and the rotation of the placement block 111 drives the screw rod 20 to rotate. The clamping process is explained as follows: the screw rod 20 is driven to rotate by rotating the turntable 22, the rotation of the screw rod 20 drives the spiral groove to rotate, and the rotation of the spiral groove drives the clamping block 21 to move up and down along the screw rod 20. When the clamping block 21 moves downward, it drives the trigger rod 23 to move and drives the penetration rod 25 to move at the same time. The movement of the trigger rod 23 drives the pressure plate 24 to move, so as to clamp the PCB circuit board. When the clamping force is too large, the pressure plate 24 is squeezed and moves upward. The pressure plate 24 moves to compress the second spring 26 and drives the penetration rod 25 to move at the same time. The trigger rod 23 moves, and the movement of the trigger rod 23 will contact the inclined surface of the card block 27, so that the card block 27 moves to the right until it is inserted into the card slot. At this time, the clamping block 21 cannot continue to clamp downwards. The anti-pinching function can effectively prevent the clamping device from causing scratches, dents or other mechanical damage to the surface of the PCB circuit board during the clamping process. This is particularly important for fragile circuits and components on the PCB circuit board, thereby affecting the function and reliability of the final product. The card block 27 is driven to move by moving the clamping block 21 upward. At this time, the inclined surface on the right side of the card block 27 contacts the card slot, so that the card block 27 moves to the left and the card block 27 is reset by the No. 3 spring. At this time, the clamping block 21 resumes the clamping effect. When the turntable 22 is rotated, the slider 29 is pulled out so that the slider 29 is out of the limit slot. At this time, the turntable 22 can be rotated to prevent the turntable from being accidentally touched by external force, resulting in an operational error in clamping. The rotation of the clamping block 21 drives the pressure rod 210 to rotate, and the clamping device is released after the PCB circuit board is flipped 180 degrees. At this time, the clamping block 21 moves downward and drives the pressure rod 210 to move. The movement of the pressure rod 210 will contact the piston block 31, so that the piston block 31 moves into the cylinder 30. Because of the vacuum setting inside the cylinder 30, the push rod 32 moves upward until it contacts the PCB circuit board, so that the PCB circuit board is tilted and slides into the discharge plate 34. When the PCB circuit board contacts the discharge plate 34, the discharge plate 34 moves downward and The sixth spring 310 is compressed to buffer the falling of the PCB circuit board and prevent the PCB circuit board from being damaged by bumps when it falls. The rotating motor 35 rotates to drive the rotating shaft 36 to rotate. The rotating shaft 36 drives the chain belt 37 to rotate. The rotation of the chain belt 37 drives the push block 38 to move. The movement of the push block 38 will contact the trigger groove of the push plate 39, so that the push plate 39 moves along the inner wall of the fixed plate 33. The movement of the push plate 39 will transport the PCB circuit board to the next processing location, thereby realizing the automation of the PCB circuit board processing and reducing the difficulty of operation for the staff.
