[0034] See also Figure 1 , Figure 2 and Figure 4 In one embodiment of the utility model, the feeding device 10 includes a frame 100, a lifting mechanism 200 and a translation mechanism 300 arranged on the frame 100, and the frame 100 has a stacking position 101, a material distribution position 102 and a material collection position 103; the lifting mechanism 200 includes an elastic member 230, a first driving member 210 and a tray 220, the first driving member 210 can drive the tray 220 to move in a vertical direction, the tray 220 is used to support the material tray 20, the elastic member 230 is arranged on the tray 220, one end of the elastic member 230 is connected to the tray 230, and the other end is used to abut the material tray 20; the translation mechanism 300 can drive the lifting mechanism 200 to move between the stacking position 101, the material distribution position 102 and the material collection position 103, so as to place the material tray 20 at the stacking position 101, the material distribution position 102 or the material collection position 103.

[0035] Specifically, the frame 100 is the main supporting structure of the feeding device 10, and is used to carry and support the lifting mechanism 200, the translation mechanism 300 and the material tray 20. The frame 100 is provided with a stacking position 101, a material distribution position 102 and a material fetching position 103. The material distribution position 102 is used for material storage. A plurality of materials, such as chips, are placed on the material tray 20, and the material tray 20 with materials is stored in the material distribution position 102; the lifting mechanism 200 and the translation mechanism 300 work together to move the material tray 20 with materials placed in the material distribution position 102 to the material fetching position 103, so as to provide materials for the next equipment of the production line; the stacking position 101 is used to recycle empty material trays 20. The stacking position 101, the material distribution position 102 and the material fetching position 103 can be arranged at intervals along the same direction on the frame 100, and the material tray 20 can move among the stacking position 101, the material distribution position 102 and the material fetching position 103 along this direction; the stacking position 101, the material distribution position 102 and the material fetching position 103 can also be distributed in a triangular shape on the frame 100, and the material tray 20 can move among the stacking position 101, the material distribution position 102 and the material fetching position 103 along a triangular route, and can also move among the stacking position 101, the material distribution position 102 and the material fetching position 103 along a circumferential direction. The arrangement order of the stacking position 101, the material distribution position 102 and the material taking position 103 can be adjusted according to the actual production line, such as the stacking position 101, the material distribution position 102 and the material taking position 103 are arranged in sequence, or the material distribution position 102, the material taking position 103 and the stacking position 101 are arranged in sequence, or the material distribution position 102, the stacking position 101, and the material taking position 103 are arranged in sequence, etc.

[0036] The elastic member 230 is provided on the tray 220 to improve the stability and protection of the material tray 20. The elastic member 230 can play a role of buffering and protection during the lifting process. With one end of the elastic member 230 connected to the tray 220 and the other end abutting against the material tray 20, the elastic member 230 can effectively absorb and reduce the vibration and impact force generated when the lifting mechanism 200 moves, protecting the tray 220 and the material tray 20 from damage.

[0037] The lifting mechanism 200 includes a first driving member 210 and a tray 220. The tray 220 is used to support the material tray 20 to ensure that it remains stable and safe during transportation and operation. The first driving member 210 can drive the tray 220 to move in the vertical direction, thereby realizing the lifting and lowering operation of the material tray 20. The translation mechanism 300 is used to realize the movement of the lifting mechanism 200 between different positions. The translation mechanism 300 can accurately control the movement of the lifting mechanism 200 between the stacking position 101, the material distribution position 102 and the material extraction position 103, so as to accurately place the material tray 20 at the desired position.

[0038] The feeding device 10 is provided with a translation mechanism 300 so that the lifting mechanism 200 can move between the stacking position 101, the material distribution position 102 and the material collection position 103, so that the lifting mechanism 200 can lift and lower the material tray 20 at the stacking position 101, the material distribution position 102 and the material collection position 103 respectively. There is no need to separately set up lifting mechanisms 200 at the stacking position 101, the material distribution position 102 and the material collection position 103, thereby reducing the number of lifting mechanisms 200 and simplifying the structure of the feeding device 10.

[0039] The translation mechanism 300 drives the lifting mechanism 200 to move to the material distribution position 102, the first driving member 210 drives the tray 220 to rise, so that the material tray 20 of the material distribution position 102 is placed on the tray 220, the first driving member 210 drives the tray 220 and the material tray 20 on the tray 220 to descend together, the translation mechanism 300 drives the lifting mechanism 200 to move to the material extraction position 103, so that the material tray 20 is also located at the material extraction position 103, after the material on the material tray 20 is taken away, the translation mechanism 300 drives the lifting mechanism 200 to move to the stacking position 101, the first driving member 210 drives the tray 220 and the empty material tray 20 on the tray 220 to rise together, the empty material tray 20 is recovered in the stacking position 101, and the first driving member 210 drives the tray 220 to descend. At this point, a feeding cycle of the feeding device 10 is completed.

[0040] The feeding device 10 uses a translation mechanism 300 and a lifting mechanism 200 to perform material distribution, transportation and stacking of the material tray 20, thereby achieving multi-position precise transportation of the material tray 20, and the feeding device 10 can realize multiple automatic cycles of material distribution, material retrieval and material stacking.

[0041] The technical solution of the utility model provides an elastic buffer between the tray 220 and the material tray 20 by arranging an elastic member 230 on the tray 220. The elastic member 230 can absorb the impact force during the lifting process, reduce the direct pressure of the tray 220 on the material tray 20, and effectively protect the integrity of the material tray 20 and the items loaded therein. The elastic buffer between the tray 220 and the material tray 20 not only reduces the risk of damage caused by mechanical hard contact, but also improves the stability and reliability of the entire feeding device 10.

[0042] In addition, the technical solution of the utility model also realizes multi-position precise transportation of the material tray 20 by using the translation mechanism 300 and the lifting mechanism 200 to divide, convey and stack the material tray 20. At the same time, driven by the translation mechanism 300, the lifting mechanism 200 can move between the stacking position 101, the material dividing position 102 and the material taking position 103, and can lift and lower the material tray 20 at the corresponding position, without separately setting the lifting mechanism 200 at the stacking position 101, the material dividing position 102 and the material taking position 103, thereby reducing the number of lifting mechanisms 200 and simplifying the structure of the feeding device 10.

[0043] In one embodiment, the feeding device 10 also includes a material storage mechanism 400, which is arranged at the stacking position 101 and / or the material distribution position 102. The material storage mechanism 400 includes a material storage rack 410, a second driving member 420 and a support member 430. The support member 430 is movably arranged on the material storage rack 410. The second driving member 420 drives the connected support member 430 and can drive the support member 430 to move toward or away from the inside of the material storage rack 410.

[0044] See also Figure 1 and Figure 4 The storage mechanism 400 is arranged at the stacking position 101 and / or the material distribution position 102 to provide storage space for the material tray 20 and ensure the safety and reliability of the storage of the material tray 20. The storage mechanism 400 includes a storage rack 410, a second driving member 420 and a supporting member 430. The storage rack 410, as a supporting structure, defines the storage space and limits the displacement of the material tray 20 in the storage space on the horizontal plane, so that multiple material trays 20 can be neatly stacked in the storage space.

[0045] The second driving member 420 is used to drive the connecting support member 430 so that the support member 430 can move in the horizontal direction. The support member 430 is used to support the material tray 20 and limit the material tray 20 from falling. The support member 430 is movably arranged on the material storage rack 410. The mobility of the support member 430 enables it to move toward or away from the inside of the material storage rack 410 as needed, that is, at least part of the support member 430 can extend into the inside of the material storage rack 410, or can extend from the inside of the material storage rack 410, so as to support the material tray 20 and release the material tray 20.

[0046] Specifically, in the initial state, the support member 430 of the material storage mechanism 400 of the material distribution position 102 extends into the material storage rack 410 and abuts against the lower surface of the material tray 20 at the lowest level, thereby vertically supporting the material tray 20 inside the material storage rack 410. The first driving member 210 drives the tray 220 to rise, so that the tray 220 is close to the lower surface of the material tray 20 at the lowest level. At this time, the second driving member 420 drives the support member 430 to move away from the inside of the material storage rack 410, and the support member 430 extends out of the inside of the material storage rack 410, and the material tray 20 falls on the tray 220. After the first driving member 210 continues to drive the tray 220 to rise to a certain distance, the second driving member 420 drives the supporting member 430 to move toward the inside of the material storage rack 410, and the supporting member 430 extends into the inside of the material storage rack 410 and extends between the two material trays 20 at the bottom layer. The first driving member 210 drives the tray 220 to descend, so that the two material trays 20 at the bottom layer are separated. After the material trays 20 on the tray 220 are lowered into place, the translation mechanism 300 drives the lifting mechanism 200 to move. At this point, the material distribution operation of the lifting mechanism 200 at the material distribution position 102 is completed.

[0047] When the material tray 20 has finished taking materials at the material taking position 103, the translation mechanism 300 drives the lifting mechanism 200 to move the empty material tray 20 to the stacking position 101. At this time, the storage mechanism 400 of the stacking position 101 remains in the initial state, and its support member 430 extends into the storage rack 410 and abuts against the lower surface of the empty material tray 20 at the bottom layer, thereby supporting the empty material tray 20 inside the storage rack 410 in the vertical direction. The first driving member 210 drives the tray 220 to rise, and the empty material tray 20 on the tray 220 approaches the supporting member 430. The second driving member 420 drives the supporting member 430 to move away from the inside of the storage rack 410, and the supporting member 430 extends out of the inside of the storage rack 410. After the first driving member 210 continues to drive the tray 220 to rise for a certain distance, the second driving member 420 drives the supporting member 430 to move toward the inside of the storage rack 410, and the supporting member 430 extends into the inside of the storage rack 410 and extends under the bottom empty material tray 20. The first driving member 210 drives the tray 220 to descend, and the empty material tray 20 falls on the supporting member 430, thereby completing the recovery of the empty material tray 20.

[0048] In one embodiment, the material storage rack 410 includes two oppositely arranged baffle assemblies 411, and at least two support members 430 are horizontally spaced and penetrated through each baffle assembly 411; the material storage mechanism 400 also includes a connecting member 440, which is arranged on the outer side of the baffle assembly 411 and connected to the support member 430 on the corresponding baffle assembly 411, and the second driving member 420 drives the connecting member 440.

[0049] See also Figure 4The storage rack 410 includes two baffle assemblies 411 arranged opposite to each other, and the baffle assemblies 411 are used to limit the movement range of the material tray 20 and provide support. The supports 430 on the two baffle assemblies 411 arranged opposite to each other can move toward each other or move away from each other at the same time. The baffle assembly 411 can be a first baffle arranged in the moving direction of the support member 430; the baffle assembly 411 can also be two second baffles arranged at the corners of the storage space, and the two second baffles are arranged at intervals perpendicular to the moving direction of the support member 430. The second baffle includes a first plate portion and a second plate portion arranged to intersect, the first plate portion is arranged in the moving direction of the support member 430, and the support member 430 is movably inserted in the first plate portion. At least two supports 430 are arranged on each baffle assembly 411, and the supports 430 are inserted in the baffle assembly 411 at intervals in the horizontal direction to ensure that the material tray 20 is evenly and stably supported. The support member 430 can be configured as a material fork, a support plate, etc.

[0050] The storage mechanism 400 also includes a connecting member 440, the function of which is to ensure that the connection between the supporting members 430 is stable and reliable, thereby ensuring the stability and load-bearing capacity of the entire storage rack 410 structure. The second driving member 420 is used to drive the connecting member 440 so that the supporting member 430 can move freely on the baffle assembly 411. In addition, one connecting member 440 simultaneously connects multiple supporting members 430 on the same baffle assembly 411. Only one second driving member 420 is required to realize the movement of multiple supporting members 430 on the same baffle assembly 411, thereby reducing the number of second driving members 420 and simplifying the structure of the storage mechanism 400. Moreover, one second driving member 420 simultaneously drives multiple supporting members 430 to move through the connecting member 440, so that the movement of multiple supporting members 430 on the same baffle assembly 411 is synchronized.

[0051] In one embodiment, the feeding device 10 further includes a limit member 500 , which is disposed at the material taking position 103 . When the lifting mechanism 200 moves to the material taking position 103 , the limit member 500 abuts against an edge of the upper surface of the material tray 20 .

[0052] See also Figure 1 and Figure 6The limiter 500 is arranged at the material taking position 103. When the lifting mechanism 200 moves to the material taking position 103, the second driving member 420 drives the tray 220 to rise, so that the limiter 500 abuts against the upper surface edge of the material tray 20. The limiter 500 plays the role of pressing the material tray 20 and limiting the position of the material tray 20, ensuring that the position of the material tray 20 is accurately controlled during the material taking process, and preventing the material tray 20 from being misplaced or tilted during the material taking process. By contacting with the upper surface edge of the material tray 20, the limiter 500 can accurately determine the position of the material tray 20, which can effectively improve the safety and stability of the material taking process, ensure the normal material taking operation, and thus improve the production efficiency and the convenience of the material taking operation. At the same time, after the material taking is completed, the lifting mechanism 200 can accurately transfer the empty material tray 20, so that the feeding device 10 has higher operating accuracy and reliability. After the material is taken out, the second driving member 420 drives the tray 220 to descend, and the translation mechanism 300 drives the lifting mechanism 200 to move to the stacking position 101 to recycle the empty tray 20. When the tray 20 moves to the material taking position 103, the stopper 500 abuts against the edge of the upper surface of the tray 20, and the elastic member 230 can effectively avoid the direct abutment between the tray 20 and the tray 220. The elastic member 230 plays a role of buffering and protecting the tray 20, effectively extending the service life of the tray 20.

[0053] In one embodiment, the stacking position 101 , the material distribution position 102 and the material extraction position 103 are sequentially arranged at intervals along the length direction of the frame 100 , and two material storage mechanisms 400 are provided, one of which is provided at the stacking position 101 and the other is provided at the material distribution position 102 .

[0054] See also Figure 2 , there are two storage mechanisms 400, one of which is set at the stacking position 101 for storing the recovered empty material trays 20; the other storage mechanism 400 is set at the material distribution position 102 for storing the material trays 20 with materials, so that both the material trays 20 with materials and the empty material trays 20 can be properly preserved. The stacking position 101, the material distribution position 102 and the material taking position 103 are arranged in sequence along the length direction of the frame 100. The material taking position 103 is at the end of the frame 100, and the space of the material taking position 103 is more spacious, which is more convenient for the material taking operation of the downstream material taking equipment. The material distribution position 102 is close to the material taking position 103, and the travel between the material distribution position 102 and the material taking position 103 is closer. The distance for the material tray 20 with materials to move from the material distribution position 102 to the material taking position 103 is smaller, which reduces the risk of accidents such as displacement and vibration of the material tray 20 during movement.

[0055] In one embodiment, the frame 100 includes a top plate 110 and at least two side plates 120 connected to the top plate 110, and the at least two side plates 120 are arranged opposite to each other. The tray 220 includes at least one supporting portion 221, and the top plate 110 is provided with at least one through hole 111 extending along its length direction corresponding to the supporting portion 221 for the supporting portion 221 to pass through.

[0056] See also Figure 4 and Figure 6 The top plate 110 and at least two side plates 120 enclose the frame 100, which is roughly in the shape of a rectangular parallelepiped, forming a stable support frame. The stacking position 101, the material distribution position 102 and the material extraction position 103 are arranged in sequence along the length direction of the top plate 110, and the two material storage mechanisms 400 are arranged at the stacking position 101 and the material distribution position 102 of the top plate 110. The tray 220 includes at least one supporting portion 221 for supporting the material tray 20. The top plate 110 is provided with at least one insertion hole 111 extending along its length direction corresponding to the supporting portion 221, so that the supporting portion 221 can pass through. The lifting mechanism 200 and the translation mechanism 300 are installed inside the frame 100, and the tray 220 can pass through the top plate 110 through the insertion hole 111 to lift and transport the material tray 20.

[0057] In one embodiment, a plurality of elastic members 230 are provided, and each supporting portion 221 is provided with at least two elastic members 230 spaced apart along the length direction thereof.

[0058] See also Figure 4 The elastic member 230 may be a spring, a rubber gasket or other elastic material. The elastic member 230 is used to provide a certain elastic support on the supporting portion 221 to absorb and disperse external loads and vibrations.
