Description

Technical Field

[0001] This invention relates to the field of overhead conveying technology, specifically an intelligent overhead conveying system for the production of intelligent displays. Background Technology

[0002] Intelligent suspended conveyor is a modern material conveying equipment that uses a top-suspended track as a carrier and combines mechanical linkage structure and intelligent control technology. It relies on the ring track and mobile hanging components erected on the top to vertically suspend and continuously transfer the workpiece. This conveying method mainly relies on the upper suspension to bear the force, and the bottom of the workpiece is completely suspended in the air and does not come into contact with the platform, conveyor belt and other structures, which can effectively avoid scratches and extrusion deformation of the workpiece surface.

[0003] During the production of the display screen, the display screen frame needs to be transported. In this process, the display screen frame needs to be suspended on the hook of the overhead conveyor. The overhead conveyor drives the movement of the display screen frame to achieve the transport of the display screen frame. During this process, the frame is very easy to shift relative to the hook due to the vibration of the overhead conveyor. This will cause friction between the frame and the hook. At the same time, when the overhead conveyor stops operating, the frame will also swing due to inertia. This will affect the transport efficiency and cause some damage to the display screen frame. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent suspension conveying system for intelligent display screen production, in order to solve the problem of friction between the frame and the hook during the conveying process of the display screen frame.

One end of the C-shaped locking block is rotatably connected to a roller shaft via a bearing. The C-shaped locking block is slidably connected to the outer connecting ring by the limiting of the roller shaft. A positioning bolt is installed on the side of the C-shaped locking block away from the roller shaft. The positioning bolt extends from the outside of the C-shaped locking block to the inside of the C-shaped locking block. A blocking roller arranged parallel to the positioning bolt is installed on one side of the C-shaped locking block. A first connecting shaft extending to the outside of the positioning block is rotatably connected to the inside of the positioning block via a bearing. A shift lever is installed at the end of the first connecting shaft away from the positioning block. A cam located inside the positioning block is provided on the outside of the first connecting shaft. A first insert rod extending to the inside of the positioning block and located below the cam is inserted into the bottom of the positioning block. First telescopic springs connected to the outside of the positioning block are provided on both sides of the first insert rod.

[0010] As a further embodiment of the present invention: the vertical movable component further includes a connecting compartment installed on the outer wall of the positioning block and located outside the first connecting shaft. A first contact piece is installed on the inner wall of the connecting compartment. A second contact piece is provided on the outer side of the first connecting shaft, located inside the connecting compartment and in contact with the first contact piece.

[0014] As a further aspect of the present invention: the top of the first insertion rod is rotatably connected to a roller via a rotating shaft, and the edge of the cam is in contact with the roller.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting a traction limiting device, the display screen frame is placed inside the hook, so that the weight of the display screen frame acts on the top of the support plate. At this time, the support plate will move downward due to the weight of the display screen frame, thereby causing the second insert rod to move relative to the hook. This makes the top of the display screen frame located inside the hook, and the hook can limit the left and right swing direction of the display screen frame. During this process, the piston rod moves downward relative to the piston cylinder, thereby expelling the air inside the piston cylinder through the solenoid valve. At the same time, the third telescopic spring is compressed by the second insert rod, thereby buffering the downward movement of the second insert rod, thus supporting the support plate of the display screen frame. The plate moves slowly downwards. During the downward movement, the second insert rod drives the spur gear to rotate via the rack, which in turn drives the second connecting shaft to rotate. This causes the extension rod on the outside of the second connecting shaft to swing. The swing of the extension rod relative to the extension frame causes the limiting roller to swing away from the hook. This causes the limiting roller to swing towards the inner wall of the display frame, thus making contact between the limiting roller and the inner wall of the display frame. This forms a bidirectional clamping and limiting mechanism on the inner side, completely restricting the frame from sliding or misaligning with the hook, preventing sliding friction between the frame and the hook, and avoiding quality defects such as scratches on the frame paint, wear on the profile, and bumps on the corners. 2. By setting a vertical movable component, the sliding block drives the positioning block to move under the operation of the main body of the suspended conveyor. When the shifting rod moves to one side of the blocking roller, the blocking roller will obstruct the shifting rod. At this time, if the positioning block continues to move, the shifting rod will swing due to the obstruction of the blocking roller, thereby causing the shifting rod to drive the first connecting shaft to rotate slightly. The rotation of the first connecting shaft causes the cam to press and guide the top of the first insert rod, thus causing the first insert rod to move down relative to the positioning block. This causes the hook to move down, thereby changing the height of the hook and reducing the overall suspension height, avoiding material collisions and misalignment caused by high positions. This reduces labor intensity and minimizes workpiece damage from impacts. Simultaneously, the second contact piece separates from the first contact piece due to the rotation of the first connecting shaft, thus de-energizing the solenoid valve and opening it. The display screen frame can then be placed inside the hook. When the shift lever separates from the blocking roller, the first connecting shaft resets under the elastic restoring force of the second telescopic spring, allowing the second contact piece to re-engage with the first contact piece, energizing and closing the solenoid valve. At this point, the air inside the piston cylinder loses its flow space, thus limiting the swinging limit roller and further improving the stability of the limit roller's position on the display screen frame.

The following describes embodiments of the invention based on its overall structure.

[0020] Please see Figures 1 to 8In this embodiment of the invention, an intelligent suspended conveyor system for manufacturing intelligent displays includes a support frame 1. A suspended conveyor body 2 is mounted on the top of the support frame 1. An outer connecting ring 3 is provided on the outer side of the suspended conveyor body 2. A sliding connecting block 7 is connected to the bottom of the suspended conveyor body 2. A positioning block 6 is provided at the bottom end of the sliding connecting block 7. A vertical movable member is provided on the inner side of the positioning block 6. A hook 13 is connected to the positioning block 6 through the vertical movable member. A second insert rod 15 extending to the bottom of the hook 13 is inserted into the inner side of the hook 13. A support plate 14 located inside the hook 13 is provided at the top of the second insert rod 15. A traction limiting member located below the hook 13 is provided at the bottom of the second insert rod 15. The traction limiting component includes an extension frame 22 installed on both sides of the hook 13. The bottom end of the suspended conveyor body 2 is rotatably connected to a second connecting shaft 23 via a bearing. An extension rod 24 is provided on the outside of the second connecting shaft 23. A limiting roller 27 is installed at the top of the extension rod 24. Spur gears 26 are installed at both ends of the second connecting shaft 23. A rack 25 located below the hook 13 is provided at the bottom of the second insert rod 15. The bottom end of the rack 25 meshes with the spur gear 26. A connecting rod 31 located below the second insert rod 15 is provided on one side of the extension frame 22. A piston cylinder 30 is installed at the top of the connecting rod 31. A solenoid valve 32 located below the connecting rod 31 is provided at the bottom end of the piston cylinder 30. A piston rod 28 extending to the inside of the piston cylinder 30 is provided at the bottom of the second insert rod 15. A third telescopic spring 29 connected to the top of the piston cylinder 30 and located outside the piston rod 28 is provided at the bottom of the second insert rod 15.

[0021] The piston cylinder 30 has an exhaust hole at its bottom, the diameter of which is smaller than the inner wall diameter of the piston cylinder 30. The outer side of the limiting roller 27 is covered with an anti-slip pad, the length of the limiting roller 27 is greater than the width of the hook 13, and there are two extension frames 22, which are symmetrically arranged along the vertical central axis of the hook 13.

[0022] In this embodiment, when transporting the display frame, the display frame is placed inside the hook 13, so that the weight of the display frame acts on the top of the support plate 14. At this time, the support plate 14 will move downward due to the weight of the display frame, thereby causing the second insert rod 15 to move relative to the hook 13, so that the top of the display frame is located inside the hook 13. The left and right swing direction of the display frame can be limited by the hook 13. During this process, the piston rod 28 moves downward relative to the piston cylinder 30, thereby venting the air inside the piston cylinder 30 through the solenoid valve 32. At the same time, the third telescopic spring 29 is compressed by the second insert rod 15, thereby buffering the downward movement of the second insert rod 15, thus supporting the display frame. The support plate 14 moves down slowly. During the downward movement, the second insertion rod 15 drives the spur gear 26 to rotate via the rack 25. This causes the spur gear 26 to drive the second connecting shaft 23 to rotate, which in turn causes the extension rod 24 on the outside of the second connecting shaft 23 to swing. The swing of the extension rod 24 relative to the extension frame 22 causes the limiting roller 27 to swing away from the hook 13. This causes the limiting roller 27 to swing towards the inner wall of the display frame, so that the limiting roller 27 contacts the inner wall of the display frame, forming a bidirectional clamping limit on the inner side. This completely restricts the frame from sliding and misaligning with the hook 13, preventing sliding friction between the frame and the hook 13, and avoiding quality defects such as scratches on the frame paint, wear on the profile, and bumps on the corners.

[0023] Please refer to this carefully. Figure 2 , Figure 4 , Figure 5 , Figure 6 The vertical moving part includes a C-shaped locking block 4 located outside the outer connecting ring 3. One end of the C-shaped locking block 4 is rotatably connected to a roller shaft 16 via a bearing. The C-shaped locking block 4 is slidably connected to the outer connecting ring 3 by the limiting of the roller shaft 16. A positioning bolt 17 is installed on the side of the C-shaped locking block 4 away from the roller shaft 16. The positioning bolt 17 extends from the outside of the C-shaped locking block 4 to the inside of the C-shaped locking block 4. A blocking roller 18 is installed on one side of the C-shaped locking block 4, which is arranged parallel to the positioning bolt 17. The inside of the positioning block 6 is rotatably connected to a first connecting shaft 8 extending to the outside of the positioning block 6 via a bearing. A shift rod 5 is installed on the end of the first connecting shaft 8 away from the positioning block 6. A cam 10 located inside the positioning block 6 is provided on the outside of the first connecting shaft 8. A first insert rod 11 extending to the inside of the positioning block 6 and located below the cam 10 is inserted into the bottom of the positioning block 6. A first telescopic spring 12 connected to the outside of the positioning block 6 is provided on both sides of the first insert rod 11. The vertical moving part also includes a connecting chamber 9 installed on the outer wall of the positioning block 6 and located outside the first connecting shaft 8. A first contact piece 19 is installed on the inner wall of the connecting chamber 9. A second contact piece 20 is provided on the outer side of the first connecting shaft 8, located inside the connecting chamber 9 and in contact with the first contact piece 19. A second telescopic spring 21 is provided on the inner wall of the connecting chamber 9, located below the first contact piece 19 and connected to the first connecting shaft 8.

[0024] Among them, the farthest distance from the top of the shift lever 5 to the bottom of the support frame 1 is greater than the farthest distance from the top of the outer connecting ring 3 to the bottom of the support frame 1. The first contact piece 19 is electrically connected to an external power supply through a wire, and the second contact piece 20 is electrically connected to the solenoid valve 32 through a wire. The center of the connecting chamber 9 is coaxial with the center of the first connecting shaft 8. The top of the first insert rod 11 is rotatably connected to a roller through a rotating shaft, and the edge of the cam 10 is in contact with the roller.

[0025] In this embodiment, the sliding block 7 drives the positioning block 6 to move under the operation of the overhead conveyor body 2. When the shifting rod 5 moves to one side of the blocking roller 18, the blocking roller 18 will obstruct the shifting rod 5. At this time, if the positioning block 6 continues to move, the shifting rod 5 will swing due to the obstruction of the blocking roller 18, thereby causing the shifting rod 5 to drive the first connecting shaft 8 to rotate slightly. The rotation of the first connecting shaft 8 causes the cam 10 to press and guide the top of the first insert rod 11, so that the first insert rod 11 can move down relative to the positioning block 6. This causes the hook 13 to move down, thereby changing the height of the hook 13 and reducing the overall suspension height, avoiding material collision and positioning difficulties caused by high positions. This reduces labor intensity and minimizes workpiece damage from impacts. Simultaneously, the second contact 20 separates from the first contact 19 due to the rotation of the first connecting shaft 8, thus de-energizing the solenoid valve 32 and placing it in the open state. The display screen frame can then be placed inside the hook 13. When the shift lever 5 separates from the blocking roller 18, the first connecting shaft 8 resets under the elastic restoring force of the second telescopic spring 21. This allows the second contact 20 to re-engage with the first contact 19, energizing and closing the solenoid valve 32. At this point, the air inside the piston cylinder 30 loses its flow space, thus limiting the swinging limiting roller 27 and further improving the stability of the limiting roller 27 in limiting the display screen frame.

[0026] The working principle of this invention is as follows: The sliding block 7, under the operation of the main body 2 of the suspended conveyor, drives the positioning block 6 to move. When the shifting rod 5 moves to one side of the blocking roller 18, the blocking roller 18 will obstruct the shifting rod 5. At this time, as the positioning block 6 continues to move, the shifting rod 5 will swing due to the obstruction of the blocking roller 18, thereby causing the shifting rod 5 to drive the first connecting shaft 8 to rotate slightly. The rotation of the first connecting shaft 8 causes the cam 10 to press and guide the top of the first insert rod 11, thus causing the first insert rod 11 to move downward relative to the positioning block 6. This causes the hook 13 to move downward, thereby changing the height of the hook 13 and lowering the overall suspension height, preventing material collisions and misalignment caused by high positions. Difficulty, reducing labor intensity, reducing workpiece collision and damage, and at the same time, the second contact piece 20 will separate from the first contact piece 19 due to the rotation of the first connecting shaft 8, thereby de-energizing the solenoid valve 32, thus putting the solenoid valve 32 in the open state, placing the display frame inside the hook 13, so that the weight of the display frame acts on the top of the support plate 14, at this time the support plate 14 will move down due to the weight of the display frame, thereby moving the second insertion rod 15 relative to the hook 13, so that the top of the display frame is located inside the hook 13, and the left and right swing direction of the display frame can be limited by the hook 13. During this process, the piston rod 28 moves down relative to the piston cylinder 30, thereby putting the piston cylinder Air inside the 30 is discharged through the solenoid valve 32. Simultaneously, the third telescopic spring 29 contracts due to the compression of the second insert rod 15, thus buffering the downward movement of the second insert rod 15. This allows the support plate 14 of the display screen frame to slowly move downward. During the downward movement, the second insert rod 15 drives the spur gear 26 to rotate via the rack 25, which in turn drives the second connecting shaft 23 to rotate. This causes the extension rod 24 on the outside of the second connecting shaft 23 to swing. The swing of the extension rod 24 relative to the extension frame 22 causes the limiting roller 27 to swing away from the hook 13, thus causing the limiting roller 27 to swing towards the inner wall of the display screen frame. 27 contacts the inner wall of the display frame, forming an inner two-way clamping limit, completely restricting the frame from sliding and misaligning relative to the hook 13, preventing sliding friction between the frame and the hook 13, and avoiding quality defects such as scratches on the frame paint, wear on the profile, and bumps on the corners. When the shift lever 5 separates from the blocking roller 18, the first connecting shaft 8 will be reset under the elastic restoring force of the second telescopic spring 21, so that the second contact piece 20 can contact the first contact piece 19 again, thereby energizing and closing the solenoid valve 32. At this time, the air inside the piston cylinder 30 will lose its flow space, thereby limiting the swinging limiting roller 27, further improving the stability of the limiting roller 27 in limiting the display frame.
