Description

Technical Field

[0001] This utility model specifically relates to a flipping mechanism for circuit board processing. Background Technology

[0002] In circuit board manufacturing, circuit boards often need to be flipped to meet double-sided processing requirements. Additionally, some production scenarios require circuit board diversion and conveying to enable simultaneous operation of different processes. Existing circuit board flipping mechanisms often suffer from limited functionality: either they can only flip and convey circuit boards without diversion, or they require pausing the conveyor belt during diversion, causing interruptions in processing continuity and severely impacting production efficiency. Utility Model Content

[0003] In view of the defects of the prior art, the technical problem to be solved by this utility model is to provide a flipping mechanism for circuit board processing.

[0004] A circuit board processing flipping mechanism includes a first conveyor belt and a second conveyor belt arranged on the same horizontal axis, and a flipping mechanism disposed between the first conveyor belt and the second conveyor belt. It also includes a third conveyor belt disposed below the second conveyor belt, and the end of the third conveyor belt near the flipping mechanism is connected to a connecting section that is arranged with a gradually inclined slope.

[0005] A flipping mechanism includes a frame and a connecting shaft rotatably mounted on the frame. Two turntables are spaced apart along the length of the connecting shaft, with the relative distance between the two turntables being greater than the width of a first conveyor belt and a connecting section, respectively. One end of the connecting section extends between the two turntables, and the end of the second conveyor belt is away from the turntables. Several grooves are evenly distributed around the circumference of each turntable, and the extension line of the groove depth direction coincides with the center of the turntable. A U-shaped carrier plate that can reciprocate along its depth direction is movably mounted in each groove. A slit is formed on the U-shaped carrier plate, which can receive the plate material fed in by the first conveyor belt. Several driving components are evenly distributed around the circumference of the connecting shaft, and each driving component corresponds to one of the U-shaped carrier plates. The driving components drive the U-shaped carrier plates to move along the depth direction of the grooves.

[0006] In one embodiment, the frame is provided with a servo motor that drives the connecting shaft to rotate.

[0007] In one embodiment, the slit is provided with a pad.

[0008] In one embodiment, the drive element is an electric telescopic rod or a cylinder.

[0009] In one embodiment, first guide limiting plates are respectively provided on both sides of the first conveyor belt.

[0010] In one embodiment, second guide limiting plates are respectively provided on both sides of the connecting section and located outside the turntable.

[0011] In one embodiment, a cushioning pad is attached to the connecting section.

[0012] In summary, the advantages of this utility model over the prior art are:

[0013] This invention, by setting up a third conveyor belt and a gradually tilting connecting section, and in conjunction with a U-shaped carrier plate on the turntable that can selectively move, allows circuit boards to be output via the second conveyor belt and also fed into the third conveyor belt via the connecting section for diversion, without interrupting equipment operation, effectively ensuring the continuity of processing and significantly improving production efficiency.

[0017] Figure 4 This is a perspective view of the flipping mechanism in one embodiment of the present invention. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1 to 4 The present invention preferably provides a circuit board processing flipping mechanism, including a first conveyor belt 1 and a second conveyor belt 2 arranged on the same horizontal axis, and a flipping mechanism disposed between the first conveyor belt 1 and the second conveyor belt 2. It also includes a third conveyor belt 3 disposed below the second conveyor belt 2. The end of the third conveyor belt 3 near the flipping mechanism is connected to a gradually inclined connecting section 4. Specifically, the conveying direction of the third conveyor belt is the same as that of the second conveyor belt, and it is used to receive the circuit boards being diverted. The connecting section is connected to the end of the third conveyor belt near the flipping mechanism. The connecting section is gradually inclined, with one end fixedly connected to the end of the third conveyor belt, and the other end extending upwards at an angle to the space between the two turntables of the flipping mechanism, forming a transition channel for the circuit board from the flipping mechanism to the third conveyor belt.

[0020] The flipping mechanism includes a frame 5 and a connecting shaft 6 rotatably mounted on the frame 5. Two turntables 7 are spaced apart along the length of the connecting shaft 6. The relative distance between the two turntables 7 is greater than the width of the first conveyor belt 1 and the connecting section 4, respectively. One end of the connecting section 4 extends between the two turntables 7. The end of the second conveyor belt 2 is away from the turntables 7. Several grooves 8 are evenly distributed around the circumference of the turntables 7, and the extension line of the depth direction of the grooves 8 coincides with the center of the turntables 7. A U-shaped carrier plate 9 that can move back and forth along its depth direction is movably disposed in the grooves 8. A slit 10 is formed on the U-shaped carrier plate 9, which can receive the plate material fed in by the first conveyor belt 1. Several driving members 11 are evenly distributed around the circumference of the connecting shaft 6. The driving members 11 are arranged one-to-one with the U-shaped carrier plates 9, and the driving members 11 drive the U-shaped carrier plates 9 to move along the depth direction of the grooves 8.

[0021] Specifically, the relative distance between the two turntables is greater than the width of the first conveyor belt and the connecting section, ensuring that the circuit boards conveyed by the first conveyor belt can smoothly enter between the two turntables, and that the connecting section can extend between the two turntables without interfering with them. The end of the second conveyor belt is positioned away from the turntables to avoid collisions between the second conveyor belt and the turntables during rotation.

[0022] During operation, the circuit board is conveyed by the first conveyor belt to the space between the two turntables. At this time, the gap of a certain U-shaped carrier plate on the turntable is exactly horizontal and aligned with the output end of the first conveyor belt. The circuit board enters the gap with the first conveyor belt. Then, the turntable is rotated by the connecting shaft, so that the circuit boards on the first conveyor belt are placed one by one into the corresponding gaps and conveyed with the rotation of the turntable. When the circuit board needs to be conveyed to the second conveyor belt, the drive unit drives the corresponding U-shaped carrier plate to move along the groove to the outside of the turntable, so that the circuit board in the gap is displaced and covers the second conveyor belt, and is output through the second conveyor belt. When the circuit board needs to be diverted to the third conveyor belt, the drive unit does not move, and the U-shaped carrier plate continues to rotate with the turntable. When it rotates to the connecting section, the circuit board in the gap tilts and slides down under the action of gravity. After being buffered by the connecting section, it falls onto the third conveyor belt to achieve diversion output.

[0023] Furthermore, the frame 5 is equipped with a servo motor 12 that drives the connecting shaft 6 to rotate. Specifically, the servo motor is fixedly mounted on one side of the frame via a motor mount, and the output shaft of the servo motor is fixedly connected to one end of the connecting shaft via a coupling. During operation, the servo motor receives signals from the control system and drives the connecting shaft to rotate at a set speed and angle through the coupling. This ensures that when the U-shaped carrier plate is in a horizontal input / output state corresponding to the first or second conveyor belt, the turntable remains stationary via the servo motor. Then, after the circuit board is fed into the corresponding slot by the first conveyor belt or sent out from the slot via the second conveyor belt, the turntable rotates again to the next angle, thereby driving the turntable to rotate synchronously. This ensures that the position of the U-shaped carrier plate is accurately controllable and guarantees the stability and consistency of the circuit board conveying and flipping actions.

[0024] Furthermore, a soft pad is provided in the gap 10. Specifically, the soft pad is made of an elastic material, preferably a silicone pad or a rubber pad, and is attached to the inner wall of the gap by adhesive or embedded installation. When the circuit board enters the gap, the soft pad can flexibly contact the surface of the circuit board, which on the one hand increases the clamping friction to prevent the circuit board from slipping; on the other hand, it can buffer the clamping force of the U-shaped carrier plate on the circuit board, avoiding scratches or pressure damage to the surface of the circuit board and protecting the processing quality of the circuit board.

[0025] Furthermore, the driving component 11 can be either an electric telescopic rod or a cylinder. Specifically, when the driving component is an electric telescopic rod, the fixed end of the electric telescopic rod is fixedly installed on the outer circumferential surface of the connecting shaft by bolts, and the telescopic end of the electric telescopic rod is fixedly connected to the bottom of the U-shaped carrier plate. The telescopic action of the electric telescopic rod drives the U-shaped carrier plate to move along the groove depth direction. When the driving component is a cylinder, the cylinder body is fixed to the connecting shaft by a bracket, the piston rod end of the cylinder is fixedly connected to the U-shaped carrier plate, and the cylinder is connected to an air source through an air pipe. The telescopic action of the piston rod drives the U-shaped carrier plate to move back and forth. Both driving methods can achieve precise displacement control of the U-shaped carrier plate and meet the driving requirements under different working conditions.

[0026] Furthermore, first guide limiting plates 13 are respectively provided on both sides of the first conveyor belt 1. Specifically, the first guide limiting plates extend along the length direction of the first conveyor belt, and the distance between the two first guide limiting plates is adapted to the width of the circuit board to be conveyed, and is slightly larger than the width of the circuit board. The first guide limiting plates are fixedly installed on the frame of the first conveyor belt by brackets, and their tops are higher than the conveying surface of the first conveyor belt. During operation, when the circuit board is conveyed on the first conveyor belt, the two sides are limited by the first guide limiting plates to prevent the circuit board from shifting laterally, ensuring that the circuit board can be accurately aligned and enter the gap of the U-shaped carrier plate.

[0027] Furthermore, second guide and limiting plates 14 are respectively provided on both sides of the connecting section 4 and on the outer side of the turntable 7. Specifically, the bottom of the second guide and limiting plate is fixedly connected to the two side edges of the connecting section, and its height is slightly higher than the thickness of the circuit board. When the circuit board slides from the gap of the U-shaped carrier plate into the connecting section, the second guide and limiting plate can guide and limit the circuit board, preventing the circuit board from shifting or falling on the connecting section, and ensuring that the circuit board is smoothly transported to the third conveyor belt.

[0028] Furthermore, a cushioning pad is attached to the connecting section 4. Specifically, the cushioning pad is made of a material with cushioning and shock-absorbing properties, preferably a sponge pad or a polyurethane foam pad, and the thickness of the cushioning pad is 3-5mm. It is evenly attached to the upper surface of the connecting section using double-sided tape or glue. When the circuit board slides from the U-shaped carrier plate to the connecting section, the cushioning pad can effectively absorb the impact force of the circuit board falling, avoiding hard contact between the circuit board and the connecting section that could cause edge or surface damage, further protecting the quality of the circuit board and reducing the defect rate during processing.
