An anti-winding rotating material handling mechanism

Abstract

An anti-winding rotating material handling mechanism includes a base, a linkage pipe, a drive component, and a pneumatic material handling component. A sleeve is mounted on the base, with a sealed rotating cavity inside. An air inlet is located outside the sleeve, connecting to the rotating cavity and used for connecting an external air supply conduit. The linkage pipe has an internal air passage, and its middle section is rotatably positioned within the rotating cavity, with a through hole connecting the rotating cavity and the air passage. Both ends of the linkage pipe extend to the outside. The drive component is mounted on the base and driven by the first end of the linkage pipe. The pneumatic material handling component is fixed to the tail end of the linkage pipe and has an air inlet connecting to the air passage. The drive component can drive the linkage pipe to rotate, thereby rotating the pneumatic material handling component. Gas supplied by the air supply conduit can sequentially pass through the air inlet, rotating cavity, through hole, air passage, and air inlet to enter the pneumatic material handling component. Because the pneumatic material handling component and the air supply conduit are independently configured, the air supply conduit can be prevented from winding during the rotation of the pneumatic material handling component, thus eliminating airway blockage and extending service life.

Description

Technical Field

[0002] With the advancement of technology, machines are gradually replacing manual labor for repetitive tasks, and more and more factories are adopting automated equipment to improve production efficiency. Among these, the rotary material handling mechanism, as a structure for transferring materials, is a key component of automated equipment.

[0003] Existing rotary material handling mechanisms mainly consist of a drive unit and a pneumatic material handling unit. The drive unit controls the rotation and movement of the pneumatic material handling unit, while the pneumatic material handling unit is used to clamp or adsorb materials. However, since the pneumatic material handling unit needs to be directly connected to the air supply duct, the air supply duct is prone to winding when the pneumatic material handling unit rotates. This may cause the air supply duct to bend and block the air passage, and it will also accelerate the aging of the air supply duct and affect its service life. In view of this, it is necessary to design an anti-winding rotary material handling mechanism to solve this problem. Utility Model Content

[0021] See appendix Figure 1 -Appendix Figure 7A rotating material handling mechanism for preventing tangling includes a base 1, a linkage pipe 2, a drive component 3, and a pneumatic material handling component 4. A sleeve 11 is mounted on the base 1. The sleeve 11 has a sealed rotating cavity 110 inside and an air inlet 12 connected to the rotating cavity 110 and used for connecting an external air supply conduit (not shown in the figure) outside the sleeve 11. The linkage pipe 2 has an internal air passage 20, and the middle part of the linkage pipe 2 is rotatably set in the rotating cavity 110 and has a through hole 21 connecting the rotating cavity 110 and the air passage 20. The two ends of the linkage pipe 2 extend to the outside. The drive component 3 is mounted on the base 1 and drivenly connected to the first end of the linkage pipe 2. The pneumatic material handling component 4 is fixed to the tail end of the linkage pipe 2 and has an air inlet 40 connected to the air passage 20.

[0022] Specifically, before use, the base 1 is installed in the automated equipment (not shown in the figure), and the air supply conduit is connected to the air source. During use, the air source is turned on to supply air to the air supply conduit. The gas in the air supply conduit can pass through the air inlet 12, the rotating cavity 110, the through hole 21, the air passage 20 and the air inlet 40 in sequence to enter the pneumatic material handling component 4, so as to control the start and stop of the pneumatic material handling component 4 to clamp or adsorb the material, thereby realizing the picking and placing of the material. During the process of supplying air to the pneumatic material handling component 4 through the air passage 20 of the linkage pipe 2, the linkage pipe 2 can also be driven by the drive component 3 to rotate, thereby driving the pneumatic material handling component 4 to rotate and move the pneumatic material handling component 4, thereby realizing the adjustment of the material position. During the rotation of the pneumatic material handling component 4, the air supply conduit connected to the air inlet 12 remains in a fixed position due to the fixed setting of the sleeve 11.

[0023] In summary, this utility model connects the pneumatic material handling component 4 by installing a linkage pipe 2 with an air passage 20 inside the sealed rotating cavity 110 of the sleeve 11, allowing the air supply conduit to be supplied with air by the air receiving end 12 on the external sleeve 11. A driving component 3 is set on the base 1 to drive the linkage pipe 2 to rotate, thereby driving the pneumatic material handling component 4 to rotate independently. Under this structural design, the air supply conduit and the pneumatic material handling component 4 are independent, which can provide a normal air source and avoid the pneumatic material handling component 4 interfering with the air supply conduit when rotating, thereby preventing the air supply conduit from bending and slowing down the aging rate of the air supply conduit, thus eliminating the blockage of the air passage 430 and extending its service life.

[0024] See appendix Figure 1 -Appendix Figure 7 Both ends of the sleeve 11 are provided with sealing sleeves 13 for mounting the linkage pipe 2. The sealing sleeves 13 abut against the inner wall of the rotating cavity 110 and the outer wall of the linkage pipe 2 and are in transition fit, so as to seal the rotating cavity 110 and allow the middle part of the linkage pipe 2 to be rotatably set in the rotating cavity 110.

[0025] Specifically, the design of the sealing sleeve 13 can improve the airtightness of the rotating cavity 110, prevent air leakage, and ensure the stability of the air supply. It can also enable the linkage pipe 2 to rotate normally around the axis of the rotating cavity 110 and smoothly drive the pneumatic material handling component 4, thus ensuring the structural stability.

[0026] The sealing sleeve 13 is usually made of materials such as rubber or elastic plastic to ensure its airtightness and wear resistance. Since there are many types of related materials, this utility model does not limit them.

[0027] See appendix Figure 1 -Appendix Figure 7 The sleeve 11 is also equipped with a bearing 14. The inner ring of the bearing 14 is fitted to abut against the outer wall of the linkage tube 2, while the outer ring of the bearing 14 abuts against the inner wall of the rotating cavity 110.

[0028] Specifically, the bearing 14 is designed to support the linkage tube 2, so that the linkage tube 2 can be placed stably and the pressure applied to the sealing sleeve 13 around the linkage tube 2 is consistent, thereby reducing the wear of the sealing sleeve 13; it can also reduce friction, so that the linkage tube 2 can rotate more easily and further improve the structural stability.

[0029] The bearing 14 mainly includes an inner ring, an outer ring, and balls. The outer ring is fitted over the inner ring, and multiple balls are provided and fill the gap between the outer ring and the inner ring. Since it is an existing product and comes in various types, it will not be described or limited in detail in this utility model.

[0030] See appendix Figure 1 -Appendix Figure 7 The sleeve 11 is also provided with a first air guide ring 15. The first air guide ring 15 is fitted to abut against the linkage pipe 2 and has a first air guide groove 151 inside. The first air guide groove 151 is annular to fully connect the through hole 21. The first air guide ring 15 is also provided with a first air guide hole 152 connecting the rotating cavity 110 and the first air guide groove 151.

[0031] Specifically, after the gas in the gas inlet 12 enters the rotating cavity 110, it can enter the first gas guide groove 151 through the first gas guide hole 152, and then enter the through hole 21 through the first gas guide groove 151 to supply gas to the air passage 20. The first gas guide groove 151 is designed to be annular to fully connect the through hole 21, which can ensure that the gas in the first gas guide groove 151 can smoothly enter the air passage 20 through the through hole 21 even when the linkage pipe 2 rotates, thus improving the stability of gas supply.

[0032] See appendix Figure 1 -Appendix Figure 7The sleeve 11 is also provided with a second air guide ring 16. The second air guide ring 16 abuts against the inner wall of the rotating cavity 110 and has a second air guide groove 161 inside. The second air guide groove 161 is annular to fully connect the air inlet end 12. The second air guide ring 16 is fitted with the first air guide ring 15 and surrounds it to form an air gap 160. The second air guide ring 16 is also provided with a second air guide hole 162 that connects the second air guide groove 161 and the air gap 160.

[0033] Specifically, after the gas in the gas inlet 12 enters the second gas guide groove 161, it can enter the air gap 160 located in the rotating cavity 110 through the second gas guide hole 162 for buffering. After being buffered, the gas in the air gap 160 will enter the first gas guide groove 151 through the first gas guide hole 152, and then enter the through hole 21 through the first gas guide groove 151 to supply gas to the gas passage 20. The second gas guide groove 161 is designed to be annular to fully connect the gas inlet 12, which can guide the gas to flow around the second gas guide ring 16 before entering the air gap 160, avoiding interference between gases. The design of the air gap 160 can also buffer the gas to a certain extent, thereby further improving the stability of the gas supply.

[0034] See appendix Figure 1 -Appendix Figure 7 The first air guide hole 152 is provided with multiple parallel circumferential arrays on the first air guide ring 15, and the second air guide hole 162 is provided with multiple parallel circumferential arrays on the second air guide ring 16.

[0035] The design of multiple second air guide holes 162 allows the gas in the second air guide groove 161 to enter the air gap 160 in the rotating cavity 110 faster and more evenly, while the design of multiple first air guide holes 152 allows the gas in the air gap 160 to enter the first air guide groove 151 faster and more evenly. Therefore, the above structural design can further improve the gas supply speed and gas supply stability.

[0036] See appendix Figure 1 -Appendix Figure 7 The driving component 3 includes a pneumatic motor (not shown in the figure) or an electric motor 31. The output shaft of the pneumatic motor or the output end of the electric motor 31 is fixedly connected to the head end of the linkage tube 2. By controlling the rotation of the output shaft of the pneumatic motor or the output end of the electric motor 31, the linkage tube 2 can be driven to rotate, thereby driving the pneumatic material picking component 4 to rotate to adjust the position of the clamped / adsorbed material.

[0037] It should be noted that, in addition to the above-mentioned components, the drive unit 3 can also be a servo motor or a brushless motor with a reduction gearbox, etc. Since there are many types of related components and they are relatively common in the mechanical field, this utility model does not impose any restrictions on them.

[0038] See appendix Figure 1 -Appendix Figure 7The pneumatic material handling component 4 is an industrial product that uses compressed gas as a medium to achieve energy conversion and transfer through pressure changes, thereby clamping or adsorbing materials. There are various types of such components, and this utility model does not limit the specific type. For ease of understanding, three embodiments are given here: Example 1 See appendix Figure 1 -Appendix Figure 7 The pneumatic material handling component 4 includes a parallel cylinder 41 and a gripper 42. The parallel cylinder 41 is installed at the end of the linkage pipe 2 and has an air inlet 40. The gripper 42 has two grippers and is respectively installed on the two support arms 411 of the parallel cylinder 41.

[0039] Specifically, when the gas in the air passage 20 enters the parallel cylinder 41 through the air inlet 40, the two arms 411 of the parallel cylinder 41 can be driven to move away from or towards each other by controlling the gas flow direction, thereby causing the two grippers 42 to clamp or release the material; and when the drive unit 3 drives the linkage tube 2 to rotate, the linkage tube 2 will also drive the parallel cylinder 41 to rotate to adjust the material position.

[0040] Furthermore, the pneumatic material handling component 4 also includes a vent seat 43. The tail end of the linkage pipe 2 is provided with a fixing block 22. The vent seat 43 is installed on the fixing block 22. The parallel cylinder 41 is installed on the vent seat 43. The vent seat 43 has an air passage 430 with a straight / bent design inside, and the air passage 430 connects the air channel 20 and the air inlet 40.

[0041] The design of the vent seat 43 provides an installation position for the parallel cylinder 41, making it convenient to disassemble and assemble the parallel cylinder 41. The design of the air passage 430 is an adaptive design to ensure that the gas in the air passage 20 can smoothly enter the parallel cylinder 41 through the air inlet 40.

[0042] On the other hand, multiple parallel cylinders 41 can be set and installed synchronously on the fixed block 22. The straight / bent air passage 430 can be a three-way or four-way, etc., to synchronously connect multiple air inlets 40 to synchronously control multiple parallel cylinders 41, thereby facilitating the synchronous handling of more materials.

[0043] Example 2 The pneumatic material handling component 4 includes a suction cup (not shown in the figure), which is installed at the end of the linkage pipe 2 and has an air inlet 40.

[0044] Specifically, when the gas in the air passage 20 enters the suction cup through the air inlet 40, it can drive the suction cup to adsorb the material. Similarly, when the air supply is stopped, it drives the suction cup to release the material. When the driving component 3 drives the linkage tube 2 to rotate, the linkage tube 2 will also drive the suction cup to rotate to adjust the position of the material.

[0045] Example 3 The pneumatic material handling component 4 includes a pneumatic motor (not shown in the figure) and a magnetic screwdriver (not shown in the figure). The pneumatic motor is installed at the end of the linkage tube 2 and has an air inlet 40. The magnetic screwdriver is installed on the output shaft of the pneumatic motor.

[0046] Specifically, after the magnetic screwdriver attracts the screw material, it supplies air to the air passage 20. When the gas in the air passage 20 enters the pneumatic motor through the air inlet 40, it can drive the magnetic screwdriver to rotate, thereby installing the screw into the corresponding hole or unscrewing it from the corresponding hole. By controlling the gas flow direction, the output shaft of the pneumatic motor can be driven to rotate forward or backward to suit different scenarios and further improve the user experience.

[0047] It should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
