Abstract
Description
Technical Field
[0001] This invention relates to the technical field of carrier recirculation, specifically to a mechanism for realizing carrier recirculation in a small space. Background Technology
[0002] The use of carrier trays is quite common in the assembly and manufacturing of various electronic products, and these trays basically circulate on the production line. Existing empty carrier tray return systems are all horizontal return systems. These horizontal return systems use flat guide tracks between the input and output tray areas. The trays in horizontal return systems flow along these guide tracks, resulting in a large footprint and potentially compressing limited normal production space. Furthermore, horizontal return systems require full support across the entire return line, leading to high costs. Summary of the Invention
[0003] To address the aforementioned problems, this invention provides a mechanism for achieving small-space return of the carrier tray. It changes the empty carrier tray from a horizontal to a vertical position by varying the height and spacing of the displacement track. After moving a certain distance, it returns to a horizontal position to restore its original position. By changing the position of the carrier tray, it can reduce the space used by the equipment during the return of the empty carrier tray and lower the equipment cost.
[0004] A mechanism for realizing the return flow of a carrier disk in a small space, characterized in that it comprises:
[0005] The empty material tray hanging area includes a first machine base, a first tray support, and a first lifting cylinder;
[0006] The return conveyor chain includes a support frame and a tray displacement guide rail arranged along the length direction. A rotating transmission chain is provided on the support frame, and several carrier hooks are arranged at intervals on the conveyor chain.
[0007] And the empty material tray hanging area, which includes a second machine base, a second tray support, and a second lifting cylinder;
[0008] The support frame covers an area on one side of the first and second machine platforms. The first and second tray supports are connected by tray displacement guide rails. The tray displacement guide rails include a first flat support guide rail, a second inward-retracting guide rail, a third vertical support guide rail, a fourth outward-expanding guide rail, and a fifth flat support guide rail. The first flat support guide rail, in conjunction with the carrier hook, transports the tray forward in a flat position. The second inward-retracting guide rail, in conjunction with the carrier hook, gradually switches the tray from a flat position to an upright position. The third vertical support guide rail, in conjunction with the carrier hook, keeps the tray upright and transports it towards the other side. The fourth outward-expanding guide rail gradually switches the tray from an upright position to a flat position. The fifth flat support guide rail, in conjunction with the carrier hook, transports the tray forward in a flat position.
[0009] Its further features are:
[0010] The carrier is changed from a flat mode to an upright mode by changing the height and spacing between the displacement track and the carrier hook connected to the carrier. After moving a distance in the upright mode, it is then changed back to the flat mode to restore the original position.
[0011] A positioning cylinder is also provided on the outside of the second tray support in the empty tray hanging area. The piston end of the positioning cylinder is used to accurately position the lateral position of the second tray support to ensure that the subsequent tray retrieval is quick and convenient.
[0012] The area between the first and second machine stations corresponding to the third vertical support rail is used to arrange other equipment, so that the space occupied by the return equipment is small.
[0013] After adopting the above technical solution, the pallet moves to the first pallet support in the empty pallet hanging area, and is then lifted by the first lifting cylinder. When the carrier hook on the transmission chain moves to below the pallet, the first lifting cylinder drops, hanging the empty pallet on the carrier hook on the transmission chain. The transmission chain carries the pallet on the displacement guide rail. As the displacement guide rail descends and approaches, the empty pallet gradually changes from lying flat to upright. Before reaching the unloading position, as the displacement guide rail rises and moves away, the empty pallet gradually returns to lying flat. When the pallet reaches the empty pallet hanging area, the second lifting cylinder lifts the pallet, detaching it from the transmission chain, completing the empty pallet return. During the pallet return process, the transmission chain drags the empty pallet onto the displacement track. By changing the height and spacing of the displacement track, the empty pallet changes from lying flat to upright. After moving a certain distance, it returns from upright to lying flat to return to its original position. Through the change of the pallet's position, the space usage of the equipment can be reduced during the empty pallet return process. Attached Figure Description

Detailed Implementation
[0021] A mechanism for achieving backflow within a small space on the carrier disk, see... Figures 1-5 It includes an empty material tray hanging area 10, a return conveyor chain 20, and an empty material tray hanging area 30.
[0022] The empty material tray hanging area 10 includes a first machine base 11, a first tray support 12, and a first lifting cylinder 13. The first machine base 11 is provided with a first tray support 12, which is used to place the tray 40. The piston end of the first lifting cylinder 13 is arranged in the opposite direction and is used to drive the tray 40 to rise.
[0023] The return conveyor chain 20 includes a motor 21, a transmission chain 22, a support frame 23 arranged along the length direction, and a tray displacement guide rail 24. The support frame 23 is equipped with a cyclically rotating transmission chain 22. The drive end of the transmission chain 22 is connected to the motor 21, and the motor 21 drives the transmission chain 22 to rotate cyclically. Several carrier hooks 25 are arranged at intervals on the transmission chain 22. The distance between the carrier hooks 25 is ensured to ensure that the normal return between adjacent trays 40 will not be affected.
[0024] The empty tray hanging area 30 includes a second machine base 31, a second tray support 32, a second lifting cylinder 33, and a positioning cylinder 34. The second machine base 31 is provided with the second tray support 32, which is used to place the tray 40. The piston end of the second lifting cylinder 33 is arranged in a certain direction and is used to drive the tray 40 to rise. The outer side of the second tray support 32 is also provided with a positioning cylinder 34, which is used to accurately position the lateral position of the second tray support 32 to ensure that the subsequent tray removal is quick and convenient.
[0025] The length of the support frame 23 covers the area on one side of the first and second machine platforms. The first tray support 12 and the second tray support 32 are connected by a tray displacement guide rail 24. The tray displacement guide rail 24 includes a first flat support guide rail 241, a second inward guide rail 242, a third vertical support guide rail 243, a fourth outward guide rail 244, and a fifth flat support guide rail 245. The first flat support guide rail 241, in conjunction with the carrier hook 25, transports the tray 40 forward in a flat position. The second inward guide rail 242, in conjunction with the carrier hook 25, gradually switches the tray 40 from a flat position to an upright position. The third vertical support guide rail 243, in conjunction with the carrier hook 25, keeps the tray 40 in an upright position and transports it towards the other side. The fourth outward guide rail 244 gradually switches the tray 40 from an upright position to a flat position. The fifth flat support guide rail 245, in conjunction with the carrier hook 25, transports the tray 40 forward in a flat position.
[0026] In practice, the carrier 40 is changed from a lying mode to an upright mode by changing the height and spacing between the displacement track 24 and the carrier hook 25 connected to the carrier. After moving a distance in an upright mode, it is changed back to a lying mode to restore its original position.
[0027] The area between the first machine base 11 and the second machine base 31 corresponding to the third vertical support guide rail 243 is used to arrange other equipment, so that the space occupied by the return equipment is small.
[0028] Its working principle is as follows: The carrier tray moves to the first carrier tray support in the empty tray hanging area, and then is lifted by the first lifting cylinder. When the carrier hook on the transmission chain moves to below the carrier tray, the first lifting cylinder drops, hanging the empty tray on the carrier hook on the transmission chain. The transmission chain carries the carrier tray on the displacement guide rail. As the displacement guide rail descends and approaches, the empty tray gradually changes from lying flat to upright. Before reaching the unloading position, as the displacement guide rail rises and moves away, the empty tray gradually returns to lying flat. When the carrier tray reaches the empty tray hanging area, the second lifting cylinder lifts the tray and disengages it from the transmission chain, completing the empty tray return. During the tray return process, the transmission chain drags the empty tray onto the displacement track. By changing the height and spacing of the displacement track, the empty tray changes from lying flat to upright. After moving a certain distance, it returns from upright to lying flat to return to its original position. By changing the position of the carrier tray, the space used by the equipment can be reduced during the empty tray return process.
