Embodiment 1
[0022] In the prior art, when the tray stops moving, due to the large total mass of the tray and the product, the stop cylinder will receive a large impact force, and it is easy to occur the situation that the stop cylinder is damaged, the position where the tray impacts is sunken, and the position of the stop cylinder is offset by being hit, resulting in inaccurate positioning of the tray and the product, and errors occur during product assembly or inspection.
[0023] Please refer to Figures 1-5, the present utility model provides a technical solution: a buffer mechanism, including a conveyor belt 1, on which a tray base 2 is provided. Inside the tray base 2, there are two piston cavities 3. At both sides of one end of the tray base 2, piston push rods 4 are movably inserted. At one end of the piston push rod 4 located inside the piston cavity 3, a piston 5 is fixedly connected. On the top of the tray base 2, there are two first through grooves 6. On the top of the tray base 2, there are two second through grooves 8. Inside the second through groove 8, a sphere 9 is provided. On the top of the tray base 2, at the top of the first through groove 6 and the second through groove 8, a sealing cover plate 19 is installed. At the bottom of the conveyor belt 1, a mounting bracket 13 is fixedly connected. On the mounting bracket 13, two stop cylinders 14 are installed; the conveyor belt 1 conveys the tray base 2. The piston rod of the stop cylinder 14 extends to block the tray base 2, so that the tray platform 12 stops at the position of the processing station. During this process, the piston push rod 4 collides with the piston rod of the stop cylinder 14. The piston push rod 4 is stressed to drive the piston 5 to move inside the piston cavity 3. The air inside the piston cavity 3 is compressed and then discharged from the inside of the first through groove 6 through the gap between the first through groove 6 and the throttle bolt 7, reducing the impact between the stop cylinder 14 and the tray base 2, preventing the stop cylinder 14 and the tray platform 12 from being damaged and deformed by impact, and preventing the position of the stop cylinder 14 from shifting, avoiding the positioning error of the products on the tray platform 12 and improving the accuracy of product assembly or detection.
[0024] A throttle bolt 7 is installed on the sealing cover plate 19. One end of the throttle bolt 7 is inserted into the inside of the first through groove 6. Through the throttle bolt 7, the size of the gap can be adjusted, thereby adjusting the air outflow speed and controlling the moving speed of the piston push rod 4; the two first through grooves 6 are communicated with the piston cavity 3, the second through groove 8 is communicated with the first through groove 6. At both ends of the top of the tray base 2, a communication groove 10 is provided. The communication groove 10 is communicated with the piston cavity 3. The communication groove 10 can facilitate the air circulation at one end of the piston cavity 3. At one end of the top of the tray base 2, a reset assembly is installed.
[0025] By setting a reset component, the piston push rod 4 can be driven to reset, thus facilitating the next buffering of the tray base 2. The reset component includes two mounting seats 15 fixedly connected to both ends of the top of the tray base 2. A fixed shaft 16 is installed between the two mounting seats 15. A dial 17 is fixedly sleeved on the outer side of the fixed shaft 16. A tray platform 12 is arranged on the top of the tray base 2. Notches 11 are formed on both sides of one end of the tray base 2. The notches 11 are matched with the dial 17. Rotating shafts 20 are movably connected to the inner sides of both sides of the conveyor belt 1. A reset wheel 18 is fixedly sleeved on the outer side of the rotating shaft 20. When the tray needs to enter the next working station, the piston rod of the stop cylinder 14 resets, and the conveyor belt 1 drives the tray base 2 to move, so that the dial 17 abuts against the reset wheel 18. The other end of the dial 17 is blocked by the reset wheel 18, so that the dial 17 rotates around the fixed shaft 16. One end of the dial 17 pushes the piston push rod 4 to move outwards. At this time, the piston push rod 4 drives the piston 5 to move inside the piston cavity 3, so that the air pressure in the first through groove 6 and the second through groove 8 decreases. Air enters through the gap between the first through groove 6 and the throttle bolt 7. At the same time, the negative pressure generated inside the first through groove 6 and the second through groove 8 can make a large amount of air enter the inside of the second through groove 8 from around the sphere 9, thus realizing the rapid movement of the piston push rod 4.
[0026] The working principle or structural principle is that the conveyor belt 1 transports the tray base 2, and the tray base 2 drives the tray platform 12 to move to the processing station. At this time, the piston rod of the stop cylinder 14 extends to block the tray base 2, so that the tray platform 12 stops at the position of the processing station. During this process, the piston push rod 4 collides with the piston rod of the stop cylinder 14, and the piston push rod 4 drives the piston 5 to move inside the piston cavity 3 under the force. The air inside the piston cavity 3 is compressed and then discharged from the inside of the first through groove 6 through the gap between the first through groove 6 and the throttle bolt 7. The size of the gap can be adjusted through the throttle bolt 7, so as to adjust the air outflow speed and control the movement speed of the piston push rod 4, reducing the impact between the stop cylinder 14 and the tray base 2. At the same time, the piston push rod 4 pushes one end of the dial 17 to move, so that the dial 17 rotates around the fixed shaft 16;
[0027] When the tray needs to enter the next working station, the piston rod of the stop cylinder 14 is reset, and the conveyor belt 1 drives the tray base 2 to move, so that the paddle 17 abuts against the reset wheel 18. The other end of the paddle 17 is blocked by the reset wheel 18, so that the paddle 17 rotates around the fixed shaft 16. One end of the paddle 17 pushes the piston push rod 4 to move outwards. At this time, the piston push rod 4 drives the piston 5 to move inside the piston cavity 3, so that the air pressure in the first through groove 6 and the second through groove 8 decreases. Air enters through the gap between the first through groove 6 and the throttle bolt 7. At the same time, the negative pressure generated inside the first through groove 6 and the second through groove 8 can make a large amount of air enter the inside of the second through groove 8 from around the sphere 9, thus realizing the rapid movement of the piston push rod 4.
