[0002] After the PCB roll substrate is produced, a conveying device is needed to stack the PCB roll substrate. In the existing technology, the PCB roll substrate is transported by a conveyor belt and the PCB roll substrate is stacked vertically by a suction cup. However, in actual use, since the PCB roll substrate has different specifications, when stacking PCB roll substrates of different widths, it is not possible to adjust according to the actual width of the PCB roll substrate, which reduces the scope of use of the device. Utility Model Content

The transmission belt is fixed to the moving frame by using a locking block at the bottom of the moving frame. After the device has been used for a long time, the transmission belt will loosen. At this time, the bolts between the fixing feet and the locking block are rotated to increase the gap between the fixing feet and the transmission belt, thereby unlocking the transmission belt.

[0023] like Figures 1 to 6 As shown, this utility model provides an automated stacking and conveying device for PCB roll substrate, including a base frame 1, a slide rail 2 fixedly installed on the top of the base frame 1, a movable frame 3 slidably connected to the top of the slide rail 2, a cylinder 27 slidably connected to the top of the movable frame 3, and the movable frame 3 having the freedom of horizontal movement. The connecting rod 5 is located above the movable frame 3 and is fixedly connected to the output end of the cylinder 27. A suction cup 6 is fixedly installed at one end of the connecting rod 5 near the center of the base frame 1. An adjustment hole 7 is provided in the middle of the movable frame 3 and the bottom of the cylinder 27. The adjustment hole 7 has a degree of freedom of movement in the front and back directions. Fixed leg 21 is fixedly installed at the bottom of the movable frame 3. A locking block 22 is fixedly installed at the bottom of the fixed leg 21. A transmission belt 23 is engaged between the locking block 22 and the fixed leg 21.

[0024] The working principle and beneficial effects of the above technical solution are as follows: When stacking PCB roll substrates of different widths, the bolts fixing the adjustment hole 7 are unscrewed according to the actual width of the PCB roll substrate. At this time, the first vacuum pump 4 and the moving frame 3 are separated. The first vacuum pump 4 can be slid to adjust the spacing between the two connecting rods 5, thereby adapting to the use of PCB roll substrates of different widths. The transmission belt 23 is fixed to the moving frame 3 by using the locking block 22 at the bottom of the moving frame 3 to engage with the transmission belt 23. After the device has been used for a long time, the transmission belt 23 will become loose. At this time, the bolts between the fixing foot 21 and the locking block 22 are rotated to increase the gap between the fixing foot 21 and the transmission belt 23, thereby unlocking the transmission belt 23. After the transmission belt 23 is taken out and cut, the two ends of the transmission belt 23 are reinserted into the fixing foot 21 and the locking block 22 to achieve stable transmission between the transmission belt 23 and the moving frame 3.

[0025] The movable frame 3 and the adjustment hole 7 in the middle of the first vacuum pump 4 are fixedly connected by bolts.

[0026] The working principle and beneficial effects of the above technical solution are as follows: The connecting rod 5 is divided into two rows, front and back, and is fixedly connected by bolts in a detachable manner. This allows the position of the first vacuum pump 4 on the moving frame 3 to be adjusted after the bolts are unscrewed, thereby adjusting the distance between the two connecting rods 5.

[0027] The base frame 1 has a fourth motor 25 fixedly installed on its left end. The output end of the fourth motor 25 is connected to a lifting rod 26. The top end of the lifting rod 26 is fixedly installed with a placement frame 8. The bottom end of the placement frame 8 is fixedly installed with a weight sensor 24.

[0028] The working principle and beneficial effects of the above technical solution are as follows: By starting the fourth motor 25, the lifting rod 26 can be driven to move up and down. The output end of the fourth motor 25 is fixedly sleeved with a gear, which meshes with the rack embedded in the left side of the lifting rod 26 to drive the lifting rod 26 to move up and down (not shown in the figure). This is existing technology and will not be described in detail here. In turn, the placement rack 8 is driven to move up and down. The weight sensor 24 supports the PCB roll substrate placed at the top of the placement rack 8. After a certain number of PCB roll substrates are placed, the first transmission roller 9 is started to rotate and send out the stacked PCB roll substrates.

[0029] The top of the placement frame 8 is rotatably connected to a first transmission roller 9, and the bottom left side of the placement frame 8 is fixedly installed with a first motor 10, which is connected to the first transmission roller 9 for transmission.

[0030] The working principle and beneficial effects of the above technical solution are as follows: The first motor 10 drives the leftmost first transmission roller 9 to rotate, and then drives all the first transmission rollers 9 to rotate through the belt drive structure sleeved on all the first transmission rollers 9, thereby driving the PCB roll substrate to move.

[0031] The base frame 1 has a fixed frame 12 fixedly installed on the right end, an adsorption plate 15 fixedly installed on the top end of the fixed frame 12, a second transmission roller 13 rotatably connected to the top end of the fixed frame 12, and a second motor 14 fixedly installed on the right end of the fixed frame 12.

[0032] The working principle and beneficial effects of the above technical solution are as follows: The output end of the second motor 14 is connected to the rightmost second transmission roller 13 via belt drive. The multiple horizontally arranged second transmission rollers 13 are connected by conveyor belt 17. When the second motor 14 is started, it can drive the second transmission roller 13 to rotate and transport the PCB roll substrate to the left.

[0033] The cylinder 27 has a first vacuum pump 4 fixedly installed at the top, which is connected to the suction cup 6. The base frame 1 has a second vacuum pump 11 fixedly installed in the middle, which is connected to the adsorption plate 15.

[0034] The working principle and beneficial effects of the above technical solution are as follows: The suction cup 6 is controlled by the first vacuum pump 4 to achieve the adsorption and placement of the PCB roll substrate. The adsorption plate 15 is controlled by the second vacuum pump 11 to achieve the adsorption and fixation of the PCB roll substrate.

[0035] The top of the adsorption plate 15 has multiple adsorption holes 16, and multiple second drive rollers 13 are connected by a conveyor belt 17. The surface of the conveyor belt 17 has multiple connecting holes 18.

[0036] The working principle and beneficial effects of the above technical solution are as follows: The principle of adsorbing and fixing PCB roll substrate is as follows: When the second vacuum pump 11 is started, since the adsorption hole 16, the adsorption plate 15 and the second vacuum pump 11 are connected, when the connecting hole 18 is above the adsorption hole 16, the adsorption hole 16 can be connected, thereby realizing that the suction force generated by the second vacuum pump 11 adsorbs the PCB roll substrate onto the conveyor belt 17.

[0037] The base frame 1 has a third motor 19 fixedly installed at the bottom end, and the left and right sides of the bottom end of the base frame 1 are rotatably connected to the third conveyor rollers 20. The transmission belt 23 is connected to the third conveyor rollers 20.

[0038] The working principle and beneficial effects of the above technical solution are as follows: by starting the third motor 19, the third conveyor roller 20 on the right side can be driven to rotate, which in turn drives the transmission belt 23 located between the two third conveyor rollers 20 to rotate.

[0039] Working principle and usage process of this utility model: The produced PCB roll substrate is placed above the conveyor belt 17 and arranged in a horizontal line. The second vacuum pump 11 is started. The second vacuum pump 11 generates suction force on the suction hole 16 through the suction plate 15. Since the connecting hole 18 on the conveyor belt 17 is aligned with the suction hole 16, the suction force can adsorb the PCB roll substrate. The third motor 19 is started to drive the third conveyor roller 20 to rotate, which in turn drives the transmission belt 23 between the two third conveyor rollers 20 to rotate, thereby driving the moving frame 3 to move. The moving frame 3 transports the connecting rod 5 and the suction cup 6 to the PCB roll substrate. Then, the cylinder 27 is started to drive the connecting rod 5 and the suction cup 6 to descend as a whole, so that the suction cup 6 contacts the PCB roll substrate. At this time, the first vacuum pump 4 is started to make the suction cup 6 adsorb the PCB roll substrate. Then, the moving frame 3 moves to the left to move the PCB roll substrate above the placement frame 8. The cylinder 27 drives the suction cup 6 to move down and place the PCB roll substrate on the first transmission roller 9. After placement, the weight sensor 24 can obtain the weight of the placement and realize the weighing function. Repeating the above operation of picking up and placing PCB roll substrates can stack multiple PCB roll substrates on the first transmission roller 9. When the weight of the PCB roll substrates on the first transmission roller 9 reaches the first threshold of the weight sensor 24, the fourth motor 25 starts and drives the gear on the output end of the fourth motor 25 to rotate, thereby driving the lifting rod 26 to move down to increase the placement space between the suction cup 6 and the first transmission roller 9. Continue to repeat the above operation of picking up and placing PCB roll substrates. When the weight of the PCB roll substrates on the first transmission roller 9 reaches the second threshold of the weight sensor 24, the first motor 10 starts and drives the first transmission roller 9 to rotate, thereby sending the stacked PCB roll substrates to the left. After the device has been used for a period of time, the transmission belt 23 will become loose. At this time, rotate the bolt between the fixed foot 21 and the locking block 22 to increase the gap between the fixed foot 21 and the transmission belt 23, thereby unlocking the transmission belt 23. Take out the transmission belt 23 and cut it to reduce the total length of the transmission belt 23. Then, reinsert the two ends of the transmission belt 23 into the fixed foot 21 and the locking block 22, ensuring that the serrated surface of the transmission belt 23 is engaged with the locking block 22. Finally, tighten the bolt to lock the locking block 22 and the transmission belt 23.
