Description

Technical Field

[0003] The lifting belt is a conveyor belt structure commonly used in the assembly line processing process. When there are too many materials on the assembly line and the processing speed is slower than the conveying speed of the conveyor belt, the lifting mechanism can be raised under the drive of the lifting device below to send the materials to the buffer device first to avoid the production line from stopping.

Therefore, it is often not suitable for high-speed processing and has low processing efficiency. Therefore, an efficient circuit board loading and lifting mechanism is proposed to solve the above problems. Utility Model Content

[0040] Reference Figure 1 、 Figure 2 and Figure 3The utility model provides an embodiment of an efficient circuit board loading and lifting mechanism, comprising a bottom plate 1, the top of the bottom plate 1 is fixedly connected to a back plate 2, the front side of the back plate 2 is fixedly connected to two slide rails 3, the front sides of the two slide rails 3 are threadedly connected with screws 20, one end of the two screws 20 are threadedly connected to the front side of the back plate 2, the screws 20 make the connection between the back plate 2 and the slide rail 3 more stable. The front sides of the two slide rails 3 are slidably connected to sliders 4, the front sides of the two sliders 4 are fixedly connected to a support plate 5, a lifting slot 6 is opened inside the support plate 5, a lifting motor 7 is provided on the rear side of the back plate 2, and a motor pad 17 is fixedly connected to the right side of the bottom plate 1. The thickness of the motor pad 17 can be adjusted, and the height of the lifting motor 7 can be adjusted, thereby adjusting the height of the eccentric wheel 9. The top of the motor pad 17 is fixedly connected to a back frame 25, and the rear side of the back frame 25 is fixedly connected to two knobs 16. The existence of the back frame 25 can make the device The connection is more precise, and the knob 16 can be installed at the same time. The bottom of the jacking motor 7 is installed on the top of the motor pad 17. The output end of the jacking motor 7 is fixedly connected to the connecting shaft 8, and one end of the connecting shaft 8 is fixedly connected to the eccentric wheel 9. The rear side of the support plate 5 is fixedly connected to the servo motor 10. A groove 18 is provided inside the support plate 5. The size of the groove 18 matches the size of the output end of the servo motor 10. The size of the output end of the servo motor 10 matches the size of the output end of the servo motor 10 so that the output end of the servo motor 10 can pass through the groove 18, thereby driving the transmission belt 11 to rotate. The top of the support plate 5 is fixedly connected to the support member 13, and the front and rear sides of the support member 13 are fixedly connected to the conveyor belt 14. The two adjacent conveyor belts 14 are fixedly connected with a rotating shaft 12. The rotating shaft 12 is connected to the output end of the servo motor 10 through the transmission belt 11. The top of the conveyor belt 14 is provided with an adsorption mechanism 15, which is used to adsorb the circuit board on the conveyor belt 14;

[0041] Specifically, when there are too many materials on the assembly line and the processing speed is slower than the conveying speed, the jacking motor 7 is started. The model of the jacking motor 7 is AZ66AC. At this time, the output end of the jacking motor 7 begins to play a role, driving the connecting shaft 8 to rotate, and then driving the eccentric wheel 9 to start rotating. When the center of the eccentric wheel 9 is located directly below the connecting shaft 8, the support plate 5 is at the lowest point. As the eccentric wheel 9 continues to rotate, when the center of the eccentric wheel 9 is located directly above the connecting shaft 8, the support plate 5 will rise to the highest point. The continuous rotation of the eccentric wheel 9 realizes the rising and falling action of the jacking device. As a circular structure, the eccentric wheel 9 has a more uniform transmission compared with the cam-driven jacking method. During the jacking process, the eccentric wheel 9 can make the rising and falling movements of the conveyor belt 14 more uniform. At the same time, the servo motor 10 starts to start. The servo motor 10 The model is MS6B4, which drives the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 further drives the two conveyor belts 14 to move. This design can not only effectively adjust the conveying state of the assembly line when there is too much material, but also ensure that the movement of the conveyor belt 14 is more stable, thereby improving the working efficiency and stability of the assembly line.

[0042] Reference Figure 1 、 Figure 2 and Figure 5 The adsorption mechanism 15 includes a vacuum generator 1501, the bottom of the vacuum generator 1501 is fixedly connected to the top of the bottom plate 1, and a generator connection port 1502 is provided on both the left and right sides of the vacuum generator 1501. A plurality of negative pressure adsorption blocks 1503 are installed on the front and rear sides of the support member 13, and a plurality of negative pressure adsorption blocks 1503 are provided on one side of each of the negative pressure adsorption blocks 1503. A plurality of air holes 1505 are provided on the surface of the conveyor belt 14. A display screen 19 is installed on the front side of the vacuum generator 1501. The vacuum generator 1501 is electrically connected to the knob 16. The display screen 19 can display the negative pressure indication. The vacuum generator 1501 is electrically connected to the knob 16 so that the knob 16 can control the vacuum generator 1501.

[0043] Specifically, before the device is operated, a series of preparatory work needs to be carried out first. The air duct is connected between the generator connection port 1502 and the adsorption block connection port 1504. This step lays the foundation for subsequent operations and starts the vacuum generator 1501. At this time, the vacuum generator 1501 starts to operate. Its function enables the inside of the negative pressure adsorption block 1503 to quickly generate negative pressure. When negative pressure is generated inside the negative pressure adsorption block 1503, a special air pressure difference phenomenon will occur, that is, the air pressure outside the conveyor belt 14 is greater than the internal air pressure of the air hole 1505. Under the action of this air pressure difference, the air hole 1505 on the conveyor belt 14 can effectively adsorb the circuit board on the conveyor belt 14. In this way, the circuit board can be prevented from jumping during the operation of the lifting mechanism. This design greatly improves the stability and reliability of the device, ensures the safety of the circuit board during transportation and processing, and provides a strong guarantee for efficient and precise production operations.

[0044] Reference Figure 1 and Figure 4 The right side of the support member 13 is fixedly connected to a connecting block 21, and the front and rear sides of the connecting block 21 are fixedly connected to connecting plates 22. The ends away from each other of the two connecting plates 22 are fixedly connected to a rotating shaft 23, and the outer walls of the two rotating shafts 23 are rotatably connected to a rotating shaft 24;

[0045] Specifically, the connecting block 21 is connected to the connecting plate 22 , and rotating the rotating shaft 23 on the connecting plate 22 can rotate the rotating shaft 24 , thereby making the conveyor belt 14 run better.

[0046] Working principle: When there are too many materials on the assembly line and the processing speed is slower than the conveying speed, the jacking motor 7 is started, and the output end of the jacking motor 7 drives the connecting shaft 8 and then drives the eccentric wheel 9 to rotate. When the center of the eccentric wheel 9 is directly below the connecting shaft 8, the support plate 5 is at the lowest point and the eccentric wheel 9 continues to rotate. When the center of the eccentric wheel 9 is directly above the connecting shaft 8, the support plate 5 is at the highest point, thereby realizing the rise and fall of the jacking device through the rotation of the eccentric wheel 9. The eccentric wheel 9 is a circle. Compared with the uneven jacking transmission driven by the cam, the eccentric wheel 9 can make the conveyor belt 14 rise and fall evenly during the jacking process. At the same time, the servo motor 10 drives the rotating shaft 12 to rotate, thereby driving the two conveyor belts 14 to move.

[0047] Before the device is operated, first connect the air duct between the generator connection port 1502 and the adsorption block connection port 1504, and start the vacuum generator 1501. At this time, the vacuum generator 1501 operates to generate negative pressure inside the negative pressure adsorption block 1503. The negative pressure generated inside the negative pressure adsorption block 1503 makes the air pressure outside the conveyor belt 14 greater than the internal air pressure of the air hole 1505. At this time, the air hole 1505 on the conveyor belt 14 can adsorb the circuit board on the conveyor belt 14, thereby preventing the circuit board from jumping during the operation of the lifting mechanism.
