Description

Technical Field

[0001] This application relates to the technical field of waste electronic product recycling, and particularly to an automatic loading device for waste electronic products at the front end of a disassembly table. Background Art

[0002] In the field of waste electronic product recycling, large household appliances such as refrigerators, washing machines, and air conditioners are key recycling targets. Taking waste refrigerators as an example, waste refrigerators not only contain recyclable materials such as steel, copper, and plastic, but also contain precious metals such as gold, silver, and palladium, and have high recycling value.

[0003] In the existing waste refrigerator recycling process, waste refrigerators are first transported to the factory by truck. After the workers unload the goods, they carry the waste refrigerators onto a trolley and use the trolley to move the refrigerator to the placement platform in front of the disassembly table. On the placement platform, the refrigerators are generally stacked (usually three layers), and then the workers directly carry the refrigerators onto the disassembly table; or use the lifting device installed on the placement platform to raise the placement platform to a certain height, and then the workers carry the refrigerators onto the disassembly table. After the refrigerator is carried onto the disassembly table, a series of subsequent disassembly operations are carried out.

[0004] However, when moving the refrigerator from the placement platform to the disassembly table, the refrigerator has a large volume, the manual handling efficiency is low, and at the same time, it is easy to cause safety hazards. Summary of the Invention

[0005] In order to improve the handling efficiency during the disassembly of waste refrigerators and reduce the safety hazards during handling, this application provides an automatic loading device for waste electronic products at the front end of a disassembly table.

[0006] An automatic loading device for waste electronic products at the front end of a disassembly table provided by this application adopts the following technical solutions: An automatic loading device for waste electronic products at the front end of a disassembly table includes a trolley, the trolley includes a frame body, and a plurality of layers of placement plates and a loading component are arranged on the frame body; The placement plate includes a first moving member, and the refrigerator entering the frame body is moved to the loading component through the first moving member; The loading component includes a loading plate and a loading driving member, the loading plate includes a second moving member, and the loading driving member is used to drive the loading plate to move in the vertical direction; the second moving member is used to drive the refrigerator to move to the placement plate or drive the refrigerator to move to the disassembly table.

[0007] By adopting the above technical solution, the refrigerator first moves to the loading plate through the first moving member, the loading driving member drives the loading plate to move in the vertical direction, and the second moving member is used to move the refrigerator to the placing plates on different layers in sequence. When the refrigerator needs to be placed on the disassembly table from the loading device, the first moving member moves the refrigerator onto the loading plate. After the loading plate moves to the height of the disassembly table, the second moving member is used to move the refrigerator onto the disassembly table.

[0008] During the process of moving the refrigerator to the disassembly table by this loading device, the labor intensity of workers is reduced, the handling efficiency is improved, and the safety risks of manual handling are reduced.

[0009] Optionally, a feeding plate is rotatably connected to the frame body, a roller shaft is rotatably arranged on the feeding plate, and the refrigerator enters the placing plate along the feeding plate, and the refrigerator abuts against the roller shaft; the feeding plate is connected with a supporting component, and the supporting component is used to support the feeding plate.

At the same time, the supporting component can support the ground, thereby improving the supporting strength of the feeding plate. During the movement of the refrigerator, the roller shaft is in rolling connection, further reducing the labor intensity of workers moving the refrigerator into the frame body. In addition, when transporting the refrigerator to the disassembly table, the feeding plate is rotated to be connected with the frame body, which can block the entrance of the refrigerator into the frame body, reducing the possibility of the refrigerator falling during the movement and reducing the safety hazard caused by the falling of the refrigerator.

[0012] By adopting the above technical solution, when the supporting component supports the feeding plate, the supporting component drives the roller shaft to move out of the discharging plate, so that the refrigerator enters the frame body through the roller shaft. When the feeding plate rotates to block the inlet of the frame body, at this time, the supporting component drives the roller shaft to move into the feeding plate, reducing the possibility of the roller shaft moving out of the feeding plate and occupying the space inside the frame body, thereby increasing the placing space of the refrigerator.

The connecting member is connected to the roller frame, the cam abuts against the connecting member, the cam is connected to the support rod, and the support rod drives the cam to rotate, so that the connecting member drives the roller frame to move; one end of the first elastic member is connected to the connecting member, and the other end is connected to the feed plate.

[0014] By adopting the above technical solution, when the support rod drives the cam to rotate, the rotation of the cam drives the connecting member to move, thereby driving the roller frame to move. Under the action of the elastic force of the second elastic member, the roller moves into or out of the feed plate.

[0015] Optionally, a locking member is further provided in the feed plate, and the locking member is used to lock the feed plate to the frame body.

[0016] By adopting the above technical solution, when the feed plate blocks the inlet of the frame body, the locking member can fix the feed plate to the frame body, improving the connection stability between the feed plate and the frame body during the movement process.

[0022] By adopting the above technical solution, after the fixing driving member moves the fixing groove to the position of the disassembly table, the clamping driving member drives the first lead screw to rotate, and the first lead screw makes the pair of clamping plates move towards each other, thereby clamping the disassembly table, reducing the possibility of the feeding device moving during feeding.

[0029] The following further elaborates on this application in conjunction with the attached Figure 1 - attached Figure 5 drawings to provide a more detailed description

[0030] An embodiment of this application discloses an automatic feeding device for waste electronic products at the front end of a disassembly table. As Figure 1 shown, it includes a trolley 1. Among them, the trolley 1 includes a frame 11 and moving wheels 12. Four moving wheels 12 are rotatably connected to the lower part of the frame 11 to facilitate the movement of the feeding device. A feeding plate 4, several layers of placing plates 2 and a feeding assembly 3 are provided on the frame 11. In this embodiment, three layers of placing plates 2 are provided

[0031] As Figure 2 and Figure 3As shown in the figure, the side where the refrigerator enters is the inlet side of the frame body 11. The feeding plate 4 is located on one side of the inlet side of the frame body 11 and is rotatably connected to the frame body 11. A plurality of roller racks 51 are provided on the feeding plate 4, and the rollers 5 are rotatably connected to the roller racks 51. A support assembly 6 is provided inside the frame body 11. The support assembly 6 includes a connecting member 61, a cam 62, a support rod 63, and a first elastic member 64. Among them, the connecting member 61 includes a connecting plate 611 and a connecting block 612. The connecting plate 611 is fixedly connected to the connecting block 612. The connecting block 612 is fixedly connected to the roller rack 51. The connecting plate 611 abuts against the cam 62, and the cam 62 is fixedly connected to the support rod 63. A first limiting groove 41 is provided inside the feeding plate 4. Both sides of the roller rack 51 abut against the inner wall of the first limiting groove 41, and the roller rack 51 can slide inside the first limiting groove 41. A plurality of first elastic members 64 are arranged inside the first limiting groove 41. Preferably, the first elastic members 64 are springs. One end of the first elastic member 64 is fixedly connected to the inner wall of the first limiting groove 41, and the other end is fixedly connected to the connecting block 612.

[0032] When the refrigerator needs to be transported into the frame body 11, the feeding plate 4 is rotated to make it contact the ground. The refrigerator can use the slope formed by the feeding plate 4 and the rollers 5 to facilitate the movement of the refrigerator into the frame body 11. At this time, the support rod 63 abuts against the ground, which can improve the support strength of the feeding plate 4. A support base 631 is fixedly connected to the bottom of the support rod 63. The support base 631 can increase the support surface and reduce the possibility of the support rod 63 rotating during the support process. When the support rod 63 supports the feeding plate 4, the convex part 621 of the cam 62 presses against the connecting plate 611, so that when the refrigerator contacts the roller 5, the roller 5 will not move, so that the refrigerator can stably abut against the roller 5, thereby reducing the friction during the movement of the refrigerator.

[0033] As Figure 1 and Figure 2 As shown in the figure, three placing plates 2 are fixedly connected inside the frame body 11. The placing plate 2 includes a first moving member 21 and a placing plate frame 22. The placing plate frame 22 is fixedly connected to the frame body 11, and the first moving member 21 is installed on the placing plate frame 22. In this embodiment, the first moving member 21 is a conveyor belt, and a driving motor is connected to the conveyor belt. When the refrigerator contacts the conveyor belt, the conveyor belt can drive the refrigerator to move. A feeding component 3 is also connected to the frame body 11. The feeding component 3 includes a feeding plate 32 and a feeding driving member 31. Among them, the feeding driving member 31 includes a first motor 311 and a second lead screw 312. The body of the first motor 311 is fixedly connected to the frame body 11. In this embodiment, two second lead screws 312 are provided. The output end of the first motor 311 is fixedly connected to one of the second lead screws 312. The two second lead screws 312 are rotatably connected to the frame body 11, and the two second lead screws 312 are connected by a conveyor belt, so that the two second lead screws 312 can rotate synchronously under the drive of the first motor 311.

[0034] As Figure 1 and Figure 2 shown, the loading plate 32 includes a second moving member 321 and a loading plate frame 322, and the second moving member 321 is installed on the loading plate frame 322. Two second lead screws 312 are threadedly connected to the loading plate frame 322. In addition, two guide rods 33 are passed through the loading plate frame 322, and the guide rods 33 are fixedly connected to the frame body 11. The first motor 311 drives the second lead screw 312 to rotate, so that the loading plate 32 can move in the vertical direction. In this embodiment, the second moving member 321 is a conveyor belt, and a driving motor is connected to the conveyor belt. When the refrigerator contacts the conveyor belt, the conveyor belt can drive the refrigerator to move.

[0035] When the refrigerator enters the frame body 11, it first enters from the bottommost placing plate 2. At this time, the loading plate 32 is at the same height as the bottommost placing plate 2. After the first moving member 21 of the bottommost placing plate 2 moves the refrigerator onto the loading plate 32, the loading driving member 31 drives the loading plate 32 to move to the height of the placing plate 2 on other layers. The second moving member 321 moves the refrigerator into the placing plate 2 on other layers, and under the drive of the first moving member 21 on this layer, the refrigerator is sequentially moved onto the placing plate 2 until this layer of the placing plate 2 is full.

[0036] As Figure 2 and Figure 4 shown, after the placing plate 2 in the frame body 11 is full, it is necessary to move the refrigerator to the disassembly table. At this time, the feeding plate 4 is rotated to block the inlet side of the frame body 11, reducing the possibility of the refrigerator falling during the movement and reducing the potential safety hazard caused by the falling of the refrigerator. A locking member 7 is provided in the feeding plate 4. The locking member 7 includes a locking rod 71, and a locking block 73 is fixedly connected to the locking rod 71. A second limiting groove 42 is provided in the feeding plate 4, and the locking block 73 is located in the second limiting groove 42. A second elastic member 72 is connected in the second limiting groove 42. Preferably, the second elastic member 72 is a spring. One end of the second elastic member 72 is fixedly connected to the locking block 73, and the other end is fixedly connected to the inner wall of the second limiting groove 42. One end of the locking rod 71 abuts against the cam 62. When the cam 62 rotates and the convex portion 621 gradually approaches the locking rod 71, the locking rod 71 moves and extends out of the feeding plate 4. At this time, the locking block 73 slides in the second limiting groove 42, and the movement direction of the locking rod 71 is restricted by the second limiting groove 42.

[0037] As Figure 5 shown, a locking port 111 is provided on the frame body 11. After the feeding plate 4 blocks the inlet side of the frame body 11, the locking rod 71 moves out of the feeding plate 4 and then enters the locking port 111 to lock the feeding plate 4 and the frame body 11.

[0038] Meanwhile, when the cam 62 rotates to move the locking rod 71 out of the feeding plate 4, the convex portion 621 gradually moves away from the connecting plate 611. Under the action of the elastic force of the first elastic member 64, the connecting block 612 moves in the first limiting groove 41 towards the cam 62, causing the roller shaft 5 to enter the feeding plate 4. When the feeding plate 4 seals the inlet side of the frame body 11, the roller shaft 5 moves into the feeding plate 4, reducing the possibility of the roller shaft 5 moving out of the feeding plate 4 and occupying the space inside the frame body 11, thereby increasing the placement space of the refrigerator.

[0039] It should be noted that in this application, by rotating the cam 62, when the refrigerator needs to be transported into the feeding device, the rotation of the cam 62 unlocks the feeding plate 4 and the frame body 11 and moves the roller shaft 5 out, facilitating the refrigerator to enter the placement plate 2 through the feeding plate 4. When the feeding device needs to transport the refrigerator to the position of the disassembly table, the rotation of the cam 62 locks the feeding plate 4 and the frame body 11 and moves the roller shaft 5 out, increasing the placement space inside the frame body 11. At the same time, it reduces the possibility of the refrigerator falling during the movement of the feeding device.

[0040] As Figure 1 and Figure 5 shown, a fixing device 8 is also fixedly connected to the frame body 11. The fixing device 8 fixes the driving member 81 and the fixing member 82. Among them, the fixing driving member 81 includes a second motor 811 and a third lead screw 812. In this embodiment, two third lead screws 812 are provided. The body of the second motor 811 is fixedly connected to the frame body 11, the output end of the second motor 811 is fixedly connected to one of the third lead screws 812, and the two third lead screws 812 are rotatably connected to the frame body 11. The two third lead screws 812 are connected by a transmission belt, enabling the second motor 811 to drive the two third lead screws 812 to rotate synchronously.

[0041] As Figure 1 and Figure 5 shown, the fixing member 82 includes a first lead screw 821, a clamping driving member 822, a fixing groove 823, and a pair of fixing plates 824. Preferably, the clamping driving member 822 is a motor. The body of the clamping driving member 822 is fixedly connected to the fixing groove 823, the output end of the clamping driving member 822 is fixedly connected to the first lead screw 821, the first lead screw 821 is rotatably connected to the fixing groove 823, and the fixing plates 824 are threadedly connected to the first lead screw 821. After the fixing driving member 81 moves the fixing groove 823 to the height of the disassembly table, the clamping driving member 822 drives the first lead screw 821 to rotate, and the first lead screw 821 drives the pair of fixing plates 824 to approach each other in the fixing groove 823, clamping the disassembly table with the pair of fixing plates 824, reducing the possibility of movement when the feeding device moves the refrigerator onto the disassembly table.

[0042] The implementation principle of the automatic feeding device for waste electronic products at the front end of the disassembly table in the embodiment of this application is as follows: When the discarded refrigerator is shipped to the placement board 2, rotate the feeding board 4 until it touches the ground, and at the same time rotate the support rod 63 to make it perpendicular to the ground. Under the action of the first elastic member 64, the connecting plate 611 always remains in contact with the cam 62. When the support rod 63 rotates to be perpendicular to the ground, the convex portion 621 of the cam 62 gradually approaches the connecting plate 611, so that the connecting plate 611 drives the connecting block 612 to move towards the roller 5. When the support rod 63 rotates to be perpendicular to the ground, the roller 5 moves out of the feeding board 4, facilitating the refrigerator to enter the bottommost placement board 2 through the roller 5.

[0043] After the refrigerator enters the bottommost placement board 2, the loading board 32 is at the same height as the bottommost placement board 2. Driven by the first moving member 21 of the bottommost placement board 2, the refrigerator first moves onto the loading board 32. Then, the loading board 32 moves in the vertical direction under the drive of the loading drive member 31, so that the refrigerator moves to the height of other placement boards 2. After the refrigerator moves to the height of other placement boards 2, the second moving member 321 drives the refrigerator to move onto other placement boards 2, and under the drive of the first moving member 21 of other placement boards 2, the refrigerators are successively placed on the placement board 2. After multiple transports by the loading assembly 3, the placement board 2 is filled with refrigerators.

[0044] After the placement board 2 is filled with refrigerators, rotate the feeding board 4 to block the inlet side of the frame 11, and rotate the support rod 63 to the vertical direction. During the rotation of the support rod 63, as the convex portion 621 of the cam 62 gradually moves away from the connecting plate 611, the connecting plate 611 moves towards the cam 62 under the action of the first elastic member 64, and then drives the connecting block 612 to move the roller 5 into the feeding board 4. At the same time, the convex portion 621 gradually approaches the locking rod 71, causing the locking rod 71 to move and extend into the locking port 111 to lock the feeding board 4 and the frame 11, improving the connection stability between the feeding board 4 and the frame 11.

[0045] When the loading device moves to the disassembly table through the moving wheels 12, the fixing drive member 81 controls the movement of the fixing member 82 and clamps the disassembly table, reducing the possibility of the loading device moving during the process of moving the refrigerator to the disassembly table.

[0046] After the fixing member 82 clamps the disassembly table, the loading board 32 moves to the height of one of the placement boards 2. After the first moving member 21 of this layer of placement board 2 drives the refrigerator to move onto the loading board 32, the loading board 32 then moves to the height of the disassembly table, and the second moving member 321 makes the refrigerator move to the disassembly table.

[0047] After multiple transports, all the refrigerators in the cart 1 are transferred to the disassembly table.

[0048] The above are all preferred embodiments of this application, and do not limit the protection scope of this application. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
