Description

Technical Field

[0001] This invention relates to the field of optical modules, and more specifically to production equipment for passive components of optical modules. Background Technology

[0002] The production line for passive components of optical modules includes testing equipment, which includes loading and unloading mechanisms, a conveying mechanism located between the loading and unloading mechanisms, and a testing mechanism. The loading mechanism receives products from other equipment on the production line and automatically conveys the products to the testing mechanism. The testing mechanism automatically tests the products, and after the tests are completed, the unloading mechanism unloads the products.

[0003] The product is positioned on a carrier tray, which is then positioned in a hopper. Workers need to move the hopper to the loading mechanism of the testing equipment. After testing, workers need to move the hopper from the unloading mechanism and transfer it to the next machine on the production line. The entire production line is linearly distributed, and workers can only work on one side of the line. To improve efficiency, workers transfer several hoppers to the loading mechanism at a time. The loading mechanism needs a certain storage capacity to facilitate the transfer of carrier trays one by one to the conveyor mechanism, where the testing mechanism inspects the products on the carrier trays. Simultaneously, the conveyor mechanism of the testing equipment needs to be close to the workers so they can easily observe the testing process and handle emergencies.

[0004] The linear layout of the entire production line requires workers to work only on one side of the line, with the conveyor system close to the workers. Simultaneously, the loading and unloading mechanism requires a certain depth to accommodate several hoppers. These hoppers are longitudinally spaced from the conveyor system near the workers. How to automatically transfer products from the hoppers to the conveyor system to improve production efficiency is a technical problem that needs to be solved. Summary of the Invention

[0005] The technical problem solved by this invention is: how to set up the loading and unloading mechanism and the conveying mechanism of the testing equipment to realize the automatic flow of products among the three, so as to improve production efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a flexible conveying mechanism for passive optical module devices, including a feeding mechanism, a flexible conveying line and a discharging mechanism. The flexible conveying line can be connected to the feeding mechanism and the discharging mechanism to receive products from the feeding mechanism and convey the products to the discharging mechanism. The flexible conveying line includes a conveying line body and a first longitudinal conveying unit and a second longitudinal conveying unit located at the two transverse ends of the conveying line body. The feeding mechanism is located beside the first longitudinal conveying unit and the discharging mechanism is located beside the second longitudinal conveying unit. The first longitudinal conveying unit is capable of longitudinal displacement and connects with the discharge end of the feeding mechanism to receive products from the feeding mechanism; the first longitudinal conveying unit that receives products can connect with the main body of the conveyor line to transfer the products to the main body of the conveyor line. The second longitudinal conveying unit is capable of longitudinal displacement and connects with the main body of the conveyor line to receive products from the main body of the conveyor line; the second longitudinal conveying unit that receives products is capable of longitudinal displacement and connects with the feeding end of the unloading mechanism to transfer the products to the unloading mechanism. Both the feeding mechanism and the unloading mechanism can transport products longitudinally. The feeding end of the feeding mechanism and the discharging end of the unloading mechanism are located on the same side of the flexible conveying mechanism.

[0007] According to the above technical solution, workers transfer the fully loaded hopper from other equipment on the production line to the feeding mechanism. Specifically, the hopper enters from the feed end of the feeding mechanism. The feeding mechanism conveys the hopper longitudinally, i.e., backward. The first longitudinal conveying unit moves longitudinally, i.e., backward, and aligns laterally with the discharge end of the feeding mechanism, achieving connection. The tray in the hopper is transferred to the first longitudinal conveying unit. Then, the first longitudinal conveying unit moves longitudinally, i.e., forward, and aligns laterally with the main body of the conveyor line, achieving connection between the two. The first longitudinal conveying unit transfers the tray to the main body of the conveyor line. The main body of the conveyor line conveys the tray laterally, i.e., from left to right, to the inspection mechanism. The inspection mechanism obtains the product from the tray on the main body of the conveyor line and inspects the product. After inspection, the product is transported back to the tray, and the tray continues to move laterally along the main body of the conveyor line to the second longitudinal conveying unit. The second longitudinal conveying unit moves longitudinally, i.e., backward, and is offset from the main body of the conveyor line. The second longitudinal conveying unit is aligned with the feed end of the unloading mechanism, and the pallet is transferred to the unloading mechanism. Then, the unloading mechanism longitudinally conveys the fully loaded hopper, i.e., forward to the discharge end. The feed end of the loading mechanism, the main body of the conveyor line, and the discharge end of the unloading mechanism are all located on the same side of the worker, who loads and unloads materials and observes the process from that side.

[0008] Based on the linear distribution of the entire production line, workers are required to work only on one side of the production line. This technical solution achieves orderly loading and unloading of products and automatic loading and unloading while ensuring that workers work on the side of the testing equipment.

[0009] A first longitudinal conveying unit is mounted on a first longitudinal conveying module, which drives the first longitudinal conveying unit to move longitudinally. The first longitudinal conveying unit includes a first conveyor belt independent of the main conveyor line, capable of lateral conveying of products. Alternatively, the first longitudinal conveying module is a screw mechanism. Driven by the first longitudinal conveying module, the first longitudinal conveying unit reciprocates between the discharge end of the loading mechanism and the feed end of the main conveyor line. When a tray is transferred to the first longitudinal conveying unit and connected to the main conveyor line, the first conveyor belt actuates, transferring the tray onto the conveyor line. The first conveyor belt is driven by an independent motor.

[0010] The second longitudinal conveying unit is mounted on the second longitudinal conveying module, which drives the second longitudinal conveying unit to move longitudinally. The second longitudinal conveying unit includes a second conveyor belt independent of the main conveyor line, capable of lateral conveying of products. Alternatively, the second longitudinal conveying module is a screw mechanism. Driven by the second longitudinal conveying module, the second longitudinal conveying unit reciprocates between the discharge end of the main conveyor line and the feed end of the unloading mechanism. The tray is transferred to the second longitudinal conveying unit, at which point the second longitudinal conveying unit connects with the main conveyor line, and the second conveyor belt actuates to receive the tray from the main conveyor line. The second conveyor belt is driven by an independent motor.

[0011] The first longitudinal conveying unit is equipped with a first blocking block and a first blocking cylinder that drives the first blocking block to rise and fall. The first blocking block is located at the end of the first conveyor belt and is used to block the products conveyed by the first conveyor belt. When a tray from the loading mechanism is transferred to the first longitudinal conveying unit, the first blocking cylinder drives the first blocking block to fall, thereby blocking the tray conveyed by the first conveyor belt. In this way, the tray can be stabilized on the first longitudinal conveying unit. Then, driven by the first longitudinal conveying module, the first longitudinal conveying unit is longitudinally displaced from the discharge end of the loading mechanism to the feed end of the conveyor line body and aligned with it. Afterward, the first blocking block rises, and the first conveyor belt can laterally convey the tray to the conveyor line body, which continues to convey the tray to the inspection mechanism.

[0012] The second longitudinal conveying unit is equipped with a second blocking block and a second blocking cylinder that drives the second blocking block to rise and fall. The second blocking block is located at the end of the second conveyor belt and is used to block the products conveyed by the second conveyor belt. When the second conveyor belt operates, the trays from the main body of the conveyor line are transferred to the second longitudinal conveying unit. The second blocking cylinder drives the second blocking block to fall, thereby blocking the trays conveyed by the second conveyor belt. In this way, the trays can be stabilized on the second longitudinal conveying unit. Subsequently, driven by the second longitudinal conveying module, the second longitudinal conveying unit is longitudinally displaced from the discharge end of the main body of the conveyor line to the feed end of the unloading mechanism and aligned with it. Afterward, the second blocking block rises, and the trays on the second conveyor belt are laterally conveyed to the unloading mechanism.

[0013] The feeding mechanism includes a first upper and lower double-layer structure, and a first lifting device located beside the first upper and lower double-layer structure. The lower layer of the first upper and lower double-layer structure is equipped with a conveyor belt, which can transport the hopper carrying the product to the first lifting device. A first pushing device is provided beside the first lifting device to push the product out of the hopper. The first lifting device is equipped with a first longitudinal displacement unit, which drives the first lifting device to move away from or towards the first upper and lower double-layer structure.

[0014] The feeding mechanism has a base plate and a vertical plate. The lower structure of the first double-layer structure is set on the base plate and the vertical plate, with the vertical plate fixed to the base plate. The upper structure of the first double-layer structure is set on the vertical plate. Workers place a fully loaded hopper on the lower structure. Driven by the conveyor belt, the hopper moves longitudinally towards the first lifting device. The first lifting device lifts the hopper on the lower structure, detaching it from the lower structure. Then, driven by the first longitudinal displacement unit, the first lifting device moves away from the lower structure, and the hopper moves away from the lower structure accordingly. The first lifting device lifts the pallet in the hopper to a certain height, making the pallet, the first pushing device, and the first longitudinal conveying unit the same height. Then, the first pushing device, located on the left side of the hopper, pushes the pallet in the hopper to the right, towards the first longitudinal conveying unit. The first longitudinal conveying unit then moves longitudinally, connecting with the main conveyor line, and conveys the pallet on it. After one pallet in the hopper is pushed away, the first lifting device rises to a certain height, so that the pallets on the next layer in the hopper are at the same height as the first pushing device and the first longitudinal conveying unit. The first pushing device then pushes the pallets of this layer back to the first longitudinal conveying unit on the right side of the hopper. The first lifting device lifts the hopper layer by layer, and the pallets are pushed sequentially to the first longitudinal conveying unit. The first longitudinal conveying unit moves back and forth between the right side of the hopper (the discharge end of the feeding mechanism) and the main body of the conveyor line, transferring the pallets one by one to the main body of the conveyor line.

[0015] After all the pallets in the hopper are pushed out, the height of the hopper becomes equal to that of the upper structure of the first double-layer structure under the action of the first lifting device. Driven by the first longitudinal displacement unit, the first lifting device approaches the upper structure and transfers the empty hoppers on it to the upper structure. After the first lifting device descends, the hopper detaches from the first lifting device and falls onto the upper structure. The conveyor belt of the lower structure transports the next fully loaded hopper towards the first lifting device, which lifts the hopper. The first pushing device pushes the pallets in the hopper one by one to the first longitudinal conveying unit. After all the pallets in the hopper have been pushed, the first lifting device transfers the empty hopper to the upper structure. The empty hopper pushes the empty hoppers already on the upper structure. In this way, the empty hoppers on the upper structure are arranged in sequence and move towards the worker's position, allowing the worker to easily remove the empty hoppers from the upper structure.

[0016] The feeding mechanism includes a second upper and lower double-layer structure, and a second lifting device located beside the second upper and lower double-layer structure. The lower layer of the second upper and lower double-layer structure is equipped with a conveyor belt, which can transport an empty hopper to the second lifting device. A second pushing device is located beside the second lifting device to push products from the flexible conveyor line into the hopper. The second lifting device is equipped with a second longitudinal displacement unit, which drives the second lifting device to move away from or towards the second upper and lower double-layer structure.

[0017] The unloading mechanism has a base plate and a vertical plate. The lower structure of the second double-layer structure is set on the base plate and the vertical plate, with the vertical plate fixed to the base plate. The upper structure of the second double-layer structure is set on the vertical plate. Workers place the empty hopper on the lower structure. Driven by the conveyor belt, the hopper moves longitudinally towards the second lifting device. The second lifting device lifts the hopper on the lower structure, detaching it from the lower structure. Then, driven by the second longitudinal displacement unit, the second lifting device moves away from the lower structure, and the hopper moves away from the lower structure accordingly. The second lifting device lifts the pallet in the hopper to a certain height, making the pallet, the second pushing device, and the second longitudinal conveying unit level. Then, the second pushing device pushes the pallet on the second longitudinal displacement unit to the right into the hopper. Afterward, the second longitudinal conveying unit moves longitudinally, connects with the main conveyor line, receives the pallet on it, and then returns to the left side of the hopper. After the hopper receives a pallet, the second lifting device rises to a certain height, making the next empty layer in the hopper level with the second pushing device and the second longitudinal conveying unit. The second pushing device then pushes the pallets from the second longitudinal conveying unit into the empty layer of the hopper. The second lifting device lifts the hopper layer by layer, filling several empty layers one by one with the pallets. Under the action of the second lifting device, the height of the hopper becomes level with the upper structure of the second double-layer structure. Driven by the second longitudinal displacement unit, the second lifting device approaches the upper structure, transferring the fully loaded hopper onto the upper structure. After the second lifting device descends, the hopper detaches from the second lifting device and falls onto the upper structure. The conveyor belt of the lower structure transports the next empty hopper towards the second lifting device, which lifts the hopper, and the second pushing device pushes the pallets from the second longitudinal conveying unit into the hopper one by one. Once the silo is full, the second lifting device transfers it to the upper structure. This silo then pushes the already full silo on the upper structure, so that the silos on the upper structure are arranged in sequence and moved toward the worker's location, allowing the worker to easily remove the full silos from the upper structure.

[0018] A detection mechanism is located on the side of the main conveyor line, between the first and second longitudinal conveyor units. The detection mechanism picks up products from the carrier tray of the main conveyor line, performs detection on the products, and then returns the products to the carrier tray. The detection information is fed back to the MES system.

[0019] The present invention has the following technical effects: First, it meets the requirement that workers can only work on one side of the production line; Secondly, the loading and unloading mechanism has a certain depth, which enables it to have storage capacity to accommodate several silos. This allows for coordination between manual handling of silos and automated equipment in terms of speed and progress, which is conducive to the orderly progress of production and the improvement of production efficiency. Third, this invention makes the entire production line neat and orderly, which is easy to manage and also makes it easier for workers to carry out their work in an orderly manner. Fourth, it ensures that the passive components of the optical module are free from loss and contamination, indirectly improving the product yield. Attached Figure Description

[0022] like Figure 1 , Figure 2 A flexible conveying mechanism for passive optical module devices includes a loading mechanism 10, a flexible conveyor line 20, and a unloading mechanism 30. The flexible conveyor line can connect to the loading and unloading mechanisms, receiving products from the loading mechanism and conveying them to the unloading mechanism. The flexible conveyor line includes a conveyor line body 21, and a first longitudinal conveying unit 22 and a second longitudinal conveying unit 23 located at both ends of the conveyor line body. The loading mechanism is located beside the first longitudinal conveying unit, and the unloading mechanism is located beside the second longitudinal conveying unit. The first longitudinal conveying unit 22 is capable of longitudinal displacement and connects to the discharge end of the loading mechanism 10 to receive products from the loading mechanism. The first longitudinal conveying unit receiving products can also connect to the conveyor line body 21 to convey products to the conveyor line body. The second longitudinal conveying unit 23 is capable of longitudinal displacement and connects to the conveyor line body to receive products from the conveyor line body. The second longitudinal conveying unit receiving products can also connect to the feed end of the unloading mechanism 30 to convey products to the unloading mechanism. Both the feeding mechanism 10 and the unloading mechanism 20 are capable of longitudinally conveying products. The feeding end of the feeding mechanism and the discharging end of the unloading mechanism are located on the same side of the flexible conveying mechanism.

[0023] like Figure 7 , Figure 8 The first longitudinal conveying unit 22 is installed on the first longitudinal conveying module 221, and the first longitudinal conveying module drives the first longitudinal conveying unit to move longitudinally. The first longitudinal conveying unit includes a first conveyor belt 222 independent of the conveyor line body 21, and the first conveyor belt is capable of transversely conveying the product.

[0024] refer to Figure 1 , Figure 7 , Figure 8The second longitudinal conveying unit 23 is installed on the second longitudinal conveying module, and the second longitudinal conveying module drives the second longitudinal conveying unit to move longitudinally. The second longitudinal conveying unit includes a second conveyor belt independent of the conveyor line body 21, and the second conveyor belt is capable of transversely conveying the product.

[0025] like Figure 7 , Figure 8 The first longitudinal conveying unit 22 is provided with a first blocking block 223 and a first blocking cylinder 224 for driving the first blocking block to rise and fall. The first blocking block is located at the end of the first conveyor belt 222 and is used to block the products conveyed by the first conveyor belt.

[0026] refer to Figure 7 , Figure 8 The second longitudinal conveying unit 23 is provided with a second blocking block and a second blocking cylinder for driving the second blocking block to rise and fall. The second blocking block is located at the end of the second conveyor belt and is used to block the products conveyed by the second conveyor belt.

[0027] Combination Figures 3 to 6 The feeding mechanism 10 includes a first upper and lower double-layer structure 11, and a first lifting device 12 located beside the first upper and lower double-layer structure. The lower layer 111 of the first upper and lower double-layer structure is provided with a conveyor belt, which can convey the hopper carrying the product to the first lifting device. A first pushing device 13 for pushing the product out of the hopper is provided beside the first lifting device. The first lifting device 12 is provided with a first longitudinal displacement unit 121, which drives the first lifting device to move away from or towards the first upper and lower double-layer structure.

[0028] Combination Figures 9 to 11 The feeding mechanism 30 includes a second upper and lower double-layer structure 31 and a second lifting device 32 located beside the second upper and lower double-layer structure. The lower layer 311 of the second upper and lower double-layer structure is provided with a conveyor belt, which can transport an empty hopper to the second lifting device. A second pushing device 33 is provided beside the second lifting device to push products on the flexible conveyor line into the hopper. The second lifting device 32 is provided with a second longitudinal displacement unit 321, which drives the second lifting device to move away from or towards the second upper and lower double-layer structure.

[0029] like Figure 1 , Figure 2 A detection mechanism 40 is provided on the side of the main body 21 of the conveyor line, and the detection mechanism is located between the first longitudinal conveying unit 22 and the second longitudinal conveying unit 23.

[0030] refer to Figure 1 , Figure 2Workers transfer the fully loaded hopper 90 from other equipment on the production line to the loading mechanism 10. Specifically, the hopper enters from the feed end 101 of the loading mechanism. The loading mechanism 10 conveys the hopper longitudinally, i.e., backward. The first longitudinal conveying unit 22 moves longitudinally, i.e., backward, and aligns laterally with the discharge end 102 of the loading mechanism, thus connecting them. The tray 91 in the hopper 90 is transferred to the first longitudinal conveying unit 22. Then, the first longitudinal conveying unit moves longitudinally, i.e., forward, and aligns laterally with the main body of the conveyor line 21, thus connecting them. The first longitudinal conveying unit 22 transfers the tray 91 to the main body of the conveyor line 21. The main body of the conveyor line conveys the tray laterally, i.e., from left to right, to the inspection mechanism 40. The inspection mechanism obtains the product from the tray on the main body of the conveyor line 21 and inspects the product. The inspection information is fed back to the MES system.

[0031] After inspection, the product is transported back to the carrier tray 91, which continues to move laterally along the main body of the conveyor line 21 to the second longitudinal conveying unit 23. The second longitudinal conveying unit moves longitudinally, that is, backward, offset from the main body of the conveyor line 21. The second longitudinal conveying unit is aligned with the feed end of the unloading mechanism 30, and the carrier tray 91 is transferred to the unloading mechanism. Then, the unloading mechanism 30 longitudinally transports the fully loaded hopper 90, that is, forward, to the discharge end. The feed end 101 of the loading mechanism, the main body of the conveyor line 21, and the discharge end 302 of the unloading mechanism are located on the same side of the worker, who loads and unloads materials and observes the process from this side.

[0032] refer to Figure 3The feeding mechanism 10 has a base plate 14 and a vertical plate 15. The lower structure 111 of the first double-layer structure is set on the base plate and the vertical plate, and the vertical plate is fixed on the base plate. The upper structure 112 of the first double-layer structure is set on the vertical plate 15. Workers place a fully loaded hopper 90 on the lower structure 111. Driven by the conveyor belt, the hopper 90 moves longitudinally towards the first lifting device 12. The first lifting device lifts the hopper 90 on the lower structure, causing it to detach from the lower structure. Then, driven by the first longitudinal displacement unit 121, the first lifting device 12 moves away from the lower structure, and the hopper 90 moves away from the lower structure accordingly. The first lifting device 12 lifts the pallet 91 in the hopper to a certain height, such that the pallet 91, the first pushing device 13, and the first longitudinal conveying unit 22 are at the same height. Then, the first pushing device 13, located on the left side of the hopper 90, pushes the pallet 91 in the hopper to the right, towards the first longitudinal conveying unit 22. Subsequently, the first longitudinal conveying unit 22 moves longitudinally to connect with the main body of the conveyor line 21, conveying the pallets 91 on it. After one pallet 91 in the hopper 90 is pushed away, the first lifting device 12 rises to a certain height, so that the pallets on the next layer in the hopper 90 are at the same height as the first pushing device 13 and the first longitudinal conveying unit 22. The first pushing device 13 pushes the pallets of this layer back to the first longitudinal conveying unit 22 on the right side of the hopper 90. The first lifting device 12 lifts the hopper 90 layer by layer, and the pallets 91 are pushed sequentially to the first longitudinal conveying unit 22. The first longitudinal conveying unit moves back and forth between the right side of the hopper and the main body of the conveyor line 21, transferring the pallets 91 one by one to the main body of the conveyor line.

[0033] refer to Figure 3 The first lifting device 12 is provided with a pair of vertically distributed grippers 122 for gripping the bottom and top of the hopper. The pair of grippers can move up and down along the frame of the first lifting device 12 to lift the hopper.

[0034] After all the pallets 91 in the hopper 90 are pushed out, the height of the hopper becomes equal to that of the upper structure 112 of the first double-layer structure under the action of the first lifting device 12. Driven by the first longitudinal displacement unit 121, the first lifting device 12 moves closer to the upper structure, transferring the empty hoppers on it to the upper structure. After the first lifting device 12 descends, the hopper 90 detaches from the first lifting device and falls onto the upper structure 112. The conveyor belt of the lower structure transports the next fully loaded hopper 90 towards the first lifting device 12. The first lifting device lifts the hopper, and the first pushing device 13 pushes the pallets 91 in the hopper one by one to the first longitudinal conveying unit 22. After all the pallets in the hopper have been pushed out, the first lifting device transfers the empty hopper to the upper structure. The empty hopper pushes the empty hoppers already located on the upper structure. In this way, the empty hoppers on the upper structure are arranged in sequence and move towards the side where the worker is located, so that the worker can easily take the empty hoppers from the upper structure.

[0035] refer to Figure 7 , Figure 8 The first longitudinal conveying module 221 is a lead screw mechanism. Driven by the first longitudinal conveying module, the first longitudinal conveying unit 22 reciprocates between the discharge end 102 of the feeding mechanism and the feed end 211 of the conveyor body. When the tray 91 is transferred to the first longitudinal conveying unit 22 and connected to the conveyor body 21, the first conveyor belt 222 actuates, transferring the tray 91 on it to the conveyor body 21. When the tray 91 from the feeding mechanism 10 is transferred to the first longitudinal conveying unit 22, the first blocking cylinder 224 drives the first blocking block 223 to descend, thereby blocking the tray 91 conveyed by the first conveyor belt 222. In this way, the tray can be stabilized on the first longitudinal conveying unit 22. Then, driven by the first longitudinal conveying module 221, the first longitudinal conveying unit 22 moves longitudinally from the discharge end 102 of the feeding mechanism to the feed end 211 of the conveyor body and aligns with it. Afterwards, the first blocking block 223 rises, and the first conveyor belt 222 is able to transport the tray 91 laterally to the main body of the conveyor line 21, and the main body of the conveyor line continues to transport the tray to the detection mechanism 40.

[0036] refer to Figure 1 , Figure 2 The testing unit 40 takes the product from the carrier tray 91 of the main body 21 of the conveyor line, tests the product, and then resets the product back onto the carrier tray.

[0037] refer to Figure 7 , Figure 8 The second longitudinal conveying module is a screw mechanism. Driven by the second longitudinal conveying module, the second longitudinal conveying unit 23 reciprocates between the discharge end 212 of the conveyor body and the feed end 301 of the unloading mechanism. The carrier tray 91 is transferred to the second longitudinal conveying unit 23, at which point the second longitudinal conveying unit is connected to the conveyor body 21, and the second conveyor belt operates to receive the carrier tray from the conveyor body 21. The carrier tray 91 from the conveyor body 21 is transferred to the second longitudinal conveying unit 23, and the second blocking cylinder drives the second blocking block to descend, thereby blocking the carrier tray 91 conveyed by the second conveyor belt. In this way, the carrier tray can be stabilized on the second longitudinal conveying unit 23. Then, driven by the second longitudinal conveying module, the second longitudinal conveying unit 23 is longitudinally displaced from the discharge end 212 of the conveyor body to the feed end 301 of the unloading mechanism and aligned with it. Afterward, the second blocking block rises, and the carrier tray 91 on the second conveyor belt is laterally conveyed to the unloading mechanism 30.

[0038] refer to Figures 9 to 11The worker places the empty hopper 90 onto the lower structure 311 of the second double-layer structure. Driven by the conveyor belt, the hopper 90 moves longitudinally towards the second lifting device 32. The second lifting device 32 lifts the hopper 90 from the lower structure, detaching it from the lower structure. Then, driven by the second longitudinal displacement unit 321, the second lifting device 32 moves away from the lower structure, and the hopper moves away from the lower structure 311 accordingly. The second lifting device 32 lifts the tray 91 in the hopper 90 to a certain height, making the tray 91, the second pushing device 33, and the second longitudinal conveying unit 23 equal in height. Then, the second pushing device 33 pushes the tray on the second longitudinal displacement unit 321 to the right into the hopper 90. Afterward, the second longitudinal conveying unit 23 moves longitudinally, connects with the main body of the conveyor line 21, receives the tray on it, and then returns to the left side of the hopper 90. After the hopper receives a pallet, the second lifting device 32 rises to a certain height, making the next empty layer in the hopper the same height as the second pushing device 33 and the second longitudinal conveying unit 23. The second pushing device 33 pushes the pallets from the second longitudinal conveying unit into the empty layer of the hopper. The second lifting device 32 lifts the hopper 90 layer by layer, filling several empty layers one by one with the pallets. Under the action of the second lifting device 32, the height of the hopper 90 is the same as the upper structure 312 of the second double-layer structure. Driven by the second longitudinal displacement unit 321, the second lifting device 32 approaches the upper structure, transferring the fully loaded hopper on it to the upper structure 312. After the second lifting device 32 descends, the hopper detaches from the second lifting device and falls onto the upper structure. The conveyor belt of the lower structure transports the next empty hopper towards the second lifting device, which lifts the hopper 90. The second pushing device 33 pushes the pallets 91 from the second longitudinal conveying unit 23 into the hopper one by one. Once the hopper is filled, the second lifting device transfers the hopper to the upper structure 312. This hopper pushes the already full hopper on the upper structure, so that the hoppers on the upper structure are arranged in sequence and moved toward the side where the worker is located, allowing the worker to easily remove the full hopper from the upper structure.

For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
