[0002] In automated assembly processes, the loading of some parts is often achieved using a tray loading method. Specifically, the required parts are placed into the tray, becoming a full tray; a set of power mechanisms transports the full tray to the robotic arm's picking position, where the robotic arm picks up the parts for automatic assembly; once all the parts in the full tray have been removed, it becomes an empty tray, at which point another set of power mechanisms removes the empty tray.

[0016] The beneficial effects of this new feeding and recycling equipment are:

[0017] In operation, this feeding and recycling equipment begins by positioning the lower lifting device in the feeding position. Since the upper and lower lifting devices are staggered in height, the upper lifting device is then in the receiving position. A full material tray is placed on the lower lifting device, completing the feeding process. Then, driven by the drive assembly, the lower lifting device moves from the feeding position to the picking position, allowing the robotic arm to perform the picking operation. Because the upper and lower lifting devices are mounted on the same conveyor belt, the upper lifting device moves synchronously with the lower lifting device.

[0018] After the robotic arm completes the material handling, the full pallet becomes an empty pallet. At this point, the lower lifting device can be used to lift the empty pallet, and the first clamping plate assembly can be used to clamp and fix the empty pallet. After the empty pallet is completely clamped and fixed by the first clamping plate assembly, the carrying end of the lower lifting device descends to exit the conveying path of the upper lifting device. Then, the drive assembly is used to switch the upper lifting device from the recovery position to the material handling position. At this time, the upper lifting device will be below the empty pallet. After the first clamping plate assembly releases its clamping action on the empty pallet, the empty pallet will be completely supported by the upper lifting device. As the upper lifting device moves from the recovery position to the material handling position, the lower lifting device will switch from the material handling position to the loading position to perform the loading operation of the next full pallet.

[0019] After the next full pallet loading operation is completed, the lower lifting device carries the full pallet at the loading position, while the upper lifting device carries the empty pallet at the unloading position. Under the action of the drive component, the full pallet will be conveyed to the unloading position along with the lower conveyor device, while the empty pallet will be conveyed to the recycling position along with the upper conveyor device.

[0020] In this feeding and recycling equipment, by placing both the lower and upper lifting devices on the same conveyor belt, a single set of drive components can switch the full material tray between the feeding and unloading positions, as well as the empty material tray between the unloading and recycling positions, significantly reducing drive costs. Furthermore, since the empty material tray can switch from the unloading to the recycling position simultaneously with the full material tray switching from the feeding to the unloading position, the two conveying actions are performed synchronously, greatly improving production efficiency.

[0035] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0036] Figure 1 This is one of the structural schematic diagrams of the feeding and recycling equipment provided in this embodiment; Figure 2 This is the second structural schematic diagram of the feeding and recycling equipment provided in this embodiment; Figure 3 This is the third structural schematic diagram of the feeding and recycling equipment provided in this embodiment. Figures 1 to 3 As shown, this embodiment provides a feeding and recycling device, including a frame 100, an upper lifting device 200, a lower lifting device 300, a first clamping plate assembly 400, and a conveying device 500. The frame 100 is provided with feeding and recycling positions spaced apart along a first horizontal direction, and a feeding position located below the recycling position. The conveying device 500 includes a conveyor belt 510 and a driving assembly 520 for driving the conveyor belt 510 to move. The conveyor belt 510 has an upper conveying section 511 and a lower conveying section 512. The first clamping plate assembly 400 is installed at the feeding position and located above the upper conveying section 511. The lower lifting device 300 is installed on the lower conveying section 512 for receiving a full pallet. The upper lifting device 200 is installed on the upper conveying section 511 for receiving an empty pallet. The lower lifting device 300 and the upper lifting device 200 are staggered in the height direction.

[0037] In this embodiment, the drive assembly 520 is configured to: drive the lower lifting device 300 from the loading position to the receiving position and cause the upper lifting device 200 to move from the receiving position to the recycling position; and drive the lower lifting device 300 from the receiving position to the loading position and cause the upper lifting device 200 to move from the recycling position to the receiving position. The switching between these two processes can be achieved by the forward and reverse rotation of the rotary motor in the drive assembly 520. By utilizing the rotary motor to output power in different directions, the conveyor belt 510 can move in two opposite directions.

[0038] In this embodiment, a full tray refers to the state when the tray 010 is filled with material, while an empty tray refers to the state when the tray 010 is not filled with material.

[0039] In operation, the lower lifting device 300 is initially positioned in the loading position. Since the upper lifting device 200 and lower lifting device 300 are staggered in height, the upper lifting device 200 is in the receiving position. A full material tray is placed on the lower lifting device 300, thus loading. Then, driven by the drive assembly 520, the lower lifting device 300 moves from the loading position to the unloading position, allowing the robotic arm to perform the unloading operation. Because the upper lifting device 200 and lower lifting device 300 are mounted on the same conveyor belt 510, the upper lifting device 200 moves synchronously with the lower lifting device 300.

[0040] After the robotic arm completes the material handling, the full material tray becomes an empty tray. At this time, the lower lifting device 300 can be used to lift the empty tray, and the first clamping plate assembly 400 can be used to clamp and fix the empty tray. After the empty tray is completely clamped and fixed by the first clamping plate assembly 400, the bearing end of the lower lifting device 300 descends to exit the conveying path of the upper lifting device 200. Then, the drive assembly 520 is used to switch the upper lifting device 200 from the recovery position to the material handling position. At this time, the upper lifting device 200 will be below the empty tray. After the first clamping plate assembly 400 releases its clamping action on the empty tray, the empty tray will be completely supported by the upper lifting device 200. As the upper lifting device 200 moves from the recovery position to the material handling position, the lower lifting device 300 will switch from the material handling position to the loading position to perform the loading operation of the next full tray.

[0041] After the next full pallet loading operation is completed, the lower lifting device 300 carries the full pallet at the loading position, while the upper lifting device 200 carries the empty pallet at the unloading position. Under the action of the drive component 520, the full pallet will be conveyed to the unloading position along with the lower lifting device 300, and at the same time, the empty pallet will be conveyed to the recycling position along with the upper lifting device 300.

[0042] In this feeding and recycling equipment, by placing both the lower lifting device 300 and the upper lifting device 200 on the same conveyor belt 510, a single set of drive components 520 can be used to switch the full material tray between the feeding and picking positions, as well as the empty material tray between the picking and recycling positions, significantly reducing drive costs. Furthermore, since the empty material tray can switch from the picking position to the recycling position simultaneously with the full material tray switching from the feeding position to the picking position, the two conveying actions are performed synchronously, greatly improving production efficiency.

[0043] Please continue to refer to Figures 1 to 3In this embodiment, the frame 100 includes a first side plate 110 and a second side plate 120 that are opposite to and spaced apart along a second horizontal direction. An upper lifting device 200 and a lower lifting device 300 are located between the first side plate 110 and the second side plate 120, and both sides of the upper lifting device 200 and the lower lifting device 300 are slidably connected to the first side plate 110 and the second side plate 120. A conveyor belt 510 is movably installed on the outer surface of the first side plate 110, and the first side plate 110 has an upper driving hole 111 and a lower driving hole 112. The upper lifting device 200 is connected to the upper conveying section 511 through the upper driving hole 111, and the lower lifting device 300 is connected to the lower conveying section 512 through the lower driving hole 112. The second horizontal direction is perpendicular to the first horizontal direction.

[0044] In this embodiment, the first horizontal direction and the second horizontal direction can be respectively referenced Figure 1 The direction indicated by the corresponding arrow.

[0045] With the above arrangement, the weight of the upper lifting device 200 and the lower lifting device 300 can be borne by the first side plate 110 and the second side plate 120. The conveyor belt 510 only provides driving force to the upper lifting device 200 and the lower lifting device 300, effectively reducing the load on the conveyor belt 510. Furthermore, by installing the conveyor belt 510 on the outer surface of the first side plate 110, the first side plate 110 can be used to separate the conveyor belt 510 from the upper lifting device 200 and the lower lifting device 300, thereby reducing motion interference and ensuring the reliability of the movement of the upper lifting device 200 and the lower lifting device 300.

[0046] Please continue to refer to Figure 1 In this embodiment, the outer surface of the first side plate 110 is provided with a plurality of synchronous pulleys, and the conveyor belt 510 is sleeved on and supported by the aforementioned synchronous pulleys; one of the synchronous pulleys can be connected to the drive assembly 520 as a drive wheel, and the remaining synchronous pulleys are rotatably mounted on the first side plate 110 as driven wheels, so that the drive assembly 520 can transmit power to each synchronous pulley, thereby driving the conveyor belt 510. The drive assembly 520 may include a rotary motor, and the drive wheel is fixedly mounted on the motor shaft of the rotary motor.

[0047] Please continue to refer to Figure 2 In this embodiment, the second side plate 120 is provided with a feeding port 121, and the feeding port 121 is provided with a feeding gate that can be opened and closed.

[0048] Using the feeding port 121, operators can drop a full material tray into the lower lifting device 300. Specifically, the full material tray can first be dropped into the feeding device 600 inside the frame 100, and then enter the lower lifting device 300 via the feeding device 600.

[0049] It should be noted that in other embodiments, the conveyor belt 510 may be installed on the outer surface of the second side plate 120, while the feeding port 121 may be opened on the first side plate 110.

[0050] Please continue to refer to Figure 1 and Figure 3 In this embodiment, the conveyor belt 510 can be a U-shaped closed annular belt, wherein the horizontal part of the U-shape is used to form the upper conveyor section 511 and the lower conveyor section 512, and the drive assembly 520 is located between the first side plate 110 and the second side plate 120.

[0051] By setting the conveyor belt 510 as a U-shaped closed loop structure, on the one hand, the extension length of the conveyor belt 510 along the first horizontal direction can be reduced, which is beneficial to reducing the width of the feeding and recycling equipment in this embodiment, thereby reducing the space occupation. On the other hand, the height of the upper conveyor section 511 and the lower conveyor section 512 can be raised, which is beneficial for the robot to grab the material in the full material tray at the picking position.

[0052] In addition, by placing the drive assembly 520 between the first side plate 110 and the second side plate 120, not only is the space between the first side plate 110 and the second side plate 120 effectively utilized, but the drive assembly 520 is also protected, reducing the adverse effects of external dust and impurities on the drive assembly 520.

[0053] Please continue to refer to Figure 3 In this embodiment, a feeding device 600 is provided at the feeding position. The feeding device 600 is provided with a lifting feeding end, which is configured to carry the material tray and drive the material tray to rise. The feeding and recycling equipment also includes a second clamping plate assembly 700, which is installed at the feeding position and located between the upper conveying section 511 and the lower conveying section 512. The second clamping plate assembly 700 is used to clamp the material tray driven to rise by the feeding device 600.

[0054] When in use, the feeding and recycling equipment allows a full pallet containing material to be placed on the feeding device 600 through the feeding port 121. The feeding device 600 then drives the full pallet to rise. When the full pallet rises to the position of the second clamping plate assembly 700, the second clamping plate assembly 700 clamps the uppermost full pallet. Afterward, the lifting and unloading end of the feeding device 600 descends, exiting the movement path of the lower lifting device 300. At the same time, subsequent full pallets can continue to be added to the feeding device 600 through the feeding port 121. When the conveyor belt 510 moves the lower lifting device 300 to below the second clamping plate assembly 700, the second clamping plate assembly 700 releases its clamping and fixing of the full pallet, allowing the full pallet to be completely carried by the lower lifting device 300. The lower lifting device 300 then moves the full pallet to the material removal position, where a robotic arm performs the material removal operation.

[0055] In this embodiment, the first clamping plate assembly 400 and the second clamping plate assembly 700 have the same structure, both consisting of telescopic cylinders simultaneously disposed on the first side plate 110 and the second side plate 120.

[0056] In this embodiment, the feeding device 600 may include a feeding motor, a synchronous belt assembly, and a feeding disc. Specifically, the two pulleys of the synchronous belt assembly are spaced apart in the vertical direction, and the synchronous belt is wound around the two pulleys. The feeding motor outputs rotational power to one of the pulleys to realize the movement of the synchronous belt. The feeding disc is fixed to the synchronous belt to form a lifting feeding end.

[0057] In other embodiments, material feeding can also be achieved by using a cylinder to lift the tray. Specifically, the piston rod of the cylinder faces upward to output power in the vertical direction, and the tray is fixedly mounted on the piston rod of the cylinder to form a lifting and feeding end.

[0058] Figure 4 for Figure 1 A magnified view of the local structure at point A. Please continue referring to this. Figure 1 and combined Figure 4In this embodiment, a recycling device 800 is provided at the recycling position. The recycling device 800 includes a recycling frame 810 and a tray support assembly 820. The recycling frame 810 is fixedly installed on the frame 100 and has an opening 811 for the tray to enter. Tray support assemblies 820 are provided at both ends of the recycling frame 810 along the second horizontal direction. The tray support assembly 820 includes a fixing member 821, a support member 822 rotatably installed on the fixing member 821, and an elastic element. The support member 822 has a horizontal support surface 8221 and a lifting inclined surface 8222 located below the support surface 8221. The lifting inclined surface 8222 extends obliquely upward toward the center of the opening 811 and is used to slide with the edge of the tray. The elastic element is disposed between the support member 822 and the fixing member 821 to keep the support surface 8221 in a horizontal position.

[0059] After the upper lifting device 200 receives the empty material tray from the picking position and transfers it to the recycling position, the upper lifting device 200 will lift the empty material tray, causing it to pass upward through the opening 811 of the recycling frame 810. During the upward movement of the empty material tray through the opening 811, the edge of the empty material tray will slide against the lifting ramp 8222 of the support member 822, causing the support member 822 to rotate relative to the fixed member 821. Once the edge of the empty material tray has completely passed the lifting ramp 8222 of the support member 822, the support member 822 will rotate and reset under the action of the elastic element, restoring the support surface 8221 to a horizontal position, thus using the support surface 8221 to support the material tray. Similarly, when the upper lifting device 200 moves the next empty material tray to the recycling position, the above actions will be repeated, causing the empty material tray to continue rising above the support member 822, stacking with the previously mentioned empty material trays, and jointly supported by the support member 822.

[0060] The aforementioned recycling device 800 enables automatic recycling and temporary storage of empty material trays, eliminating the tedious process of manually recycling each empty material tray one by one, and greatly saving labor costs.

[0061] Please continue to refer to Figure 4 In this embodiment, the tray support assembly 820 further includes a rotating shaft 823. There are two fixing members 821, which are spaced apart along the first horizontal direction. The rotating shaft 823 is fixedly connected between the two fixing members 821. There are two support members 822, which are rotatably mounted on the rotating shaft 823. The elastic element includes a torsion spring. A torsion spring is provided between each support member 822 and the rotating shaft 823 to provide a reset force for the support member 822.

[0062] Please continue to refer to Figure 1In this embodiment, the recycling device 800 may further include a guide component 830, wherein the recycling frame 810 is provided with guide components 830 at both ends along the first horizontal direction, and the guide components 830 are used to guide the material tray to rise and fall.

[0063] The aforementioned guide component 830 not only guides the lifting and lowering process of the tray, but also forms a tray storage space, so that after the tray is temporarily stored in the recycling position, it can be accommodated between the guide components 830 on both sides. The guide components 830 limit the tray and prevent it from sliding off to the side.

[0064] Figure 5 This is a schematic diagram of the upper lifting device 200 of the feeding and recycling equipment provided in this embodiment; Figure 6 This is a structural side view of the upper lifting device 200 of the feeding and recycling equipment provided in this embodiment. Figure 5 and Figure 6 As shown, in this embodiment, the upper lifting device 200 may include a first top plate 210, a first bottom plate 220, a first motor 230, a first lead screw 240, a first lifting rod 250, and a second lifting rod 260. The first top plate 210 and the first bottom plate 220 are spaced apart in the vertical direction. The first lead screw 240 is horizontally arranged and rotatably mounted on the first bottom plate 220. The first motor 230 is mounted on the first bottom plate 220 and connected to the first lead screw 240, and the first motor 230 is used to drive the first lead screw 240 to rotate. The first lifting rod... The first end of the first lifting rod 250 is rotatably connected to the first base plate 220, and the second end of the first lifting rod 250 is slidably installed on the first top plate 210, with the sliding direction along the extension direction of the first lead screw 240; the first end of the second lifting rod 260 is rotatably connected to the first top plate 210, and the second end of the second lifting rod 260 is spirally fitted onto the first lead screw 240 and slidably connected to the first base plate 220, with the sliding direction along the extension direction of the first lead screw 240; the first lifting rod 250 and the second lifting rod 260 are rotatably connected in the middle to form a fork-scissor structure.

[0065] When it is necessary to raise or lower the tray placed on the first top plate 210, the first motor 230 starts, driving the first lead screw 240 to rotate. Under the action of the helical connection between the second lifting rod 260 and the first lead screw 240 and the sliding connection between the second lifting rod 260 and the first bottom plate 220, the second lifting rod 260 will move up and down. At the same time, under the action of the rotational connection between the second lifting rod 260 and the first lifting rod 250 and the sliding connection between the first lifting rod 250 and the first top plate 210, the first lifting rod 250 will move up and down synchronously with the second lifting rod 260, realizing the lifting and lowering drive of the first top plate 210, thereby driving the tray to rise and fall. The rising and falling of the first top plate 210 is achieved by the forward and reverse rotation of the first motor 230.

[0066] The upper lifting device 200 is designed in this way to achieve smooth rising and falling of the material tray with high motion precision.

[0067] Similarly, the lower lifting device 300 includes a second top plate, a second bottom plate, a second motor, a second lead screw, a third lifting rod, and a fourth lifting rod. The second top plate and the second bottom plate are spaced apart vertically. The second lead screw is horizontally arranged and rotatably mounted on the second bottom plate. The second motor is mounted on the second bottom plate and connected to the second lead screw, driving the second lead screw to rotate. The first end of the third lifting rod is rotatably connected to the second bottom plate, and the second end is slidably mounted on the second top plate, sliding in the direction of extension of the second lead screw. The first end of the fourth lifting rod is rotatably connected to the second top plate, and the second end is helically fitted onto the second lead screw and slidably connected to the second bottom plate, sliding in the direction of extension of the second lead screw. The third and fourth lifting rods are rotatably connected at the middle, forming a scissor structure. The rising and falling of the second top plate is achieved by the forward and reverse rotation of the second motor.

[0068] In other words, the structure of the lower lifting device 300 is the same as that of the upper lifting device 200, and it can also achieve the smooth lifting of the material tray. Therefore, the working process of the lower lifting device 300 will not be described in detail.

[0069] Please continue to refer to Figure 5 The upper lifting device 200 includes a first buffer 270, which is mounted on the first base plate 220. The first buffer 270 is configured to engage with the second end of the second lifting rod 260 after the first top plate 210 has descended to its maximum stroke.

[0070] The aforementioned first buffer 270 can limit the maximum descent stroke of the first top plate 210 during its descent. On the one hand, it prevents the second lifting rod 260 from slipping off the first bottom plate 220 due to excessive movement of the first top plate 210. On the other hand, it can also buffer the impact force of the second lifting rod 260.

[0071] Similarly, the lower-level lifting device 300 includes a second buffer mounted on the second base plate. The second buffer is configured to engage with the second end of the fourth lifting rod after the second top plate has descended to its maximum stroke. The function of the second buffer in the lower-level lifting device 300 is the same as the function of the first buffer 270 in the upper-level lifting device 200, and therefore will not be described further.

[0072] The first buffer 270 and the second buffer can be hydraulic buffers.

[0073] Please continue to refer to Figures 1 to 3In this embodiment, the frame 100 is provided with an upper guide rail 130 and a lower guide rail 140, both extending along a first horizontal direction. An upper lifting device 200 is slidably mounted on the upper guide rail 130, and a lower lifting device 300 is slidably mounted on the lower guide rail 140. The first side upright plate 110 and the second side upright plate 120 are both simultaneously fixedly provided with the upper guide rail 130 and the lower guide rail 140.

[0074] The above-mentioned configuration can improve the smoothness of sliding between the upper lifting device 200 and the lower lifting device 300 between the first side plate 110 and the second side plate 120.

[0075] The working process of this feeding and recycling equipment is as follows:

[0076] A stack of full pallets filled with material is placed into the feeding device 600 through the feeding port 121. The feeding device 600 lifts the full pallets to the position of the second clamping plate assembly 700. The second clamping plate assembly 700 actuates, clamping the uppermost full pallet. The lifting feeding end of the feeding device 600 descends, exiting the conveying path of the lower lifting device 300. The drive assembly 520 actuates, driving the conveyor belt 510 to move, so that the lower lifting device 300 moves to below the second clamping plate assembly 700, while the upper lifting device 200 moves synchronously to the material picking position. When the lower lifting device 300 moves to the second clamping plate assembly... After the material is below part 700, the clamping and fixing of the second clamping plate assembly 700 on the full material tray is released, so that the full material tray is completely supported by the lower lifting device 300; the drive assembly 520 continues to operate, causing the lower lifting device 300 and the full material tray it carries to move to the material picking position, while at the same time, the upper lifting device 200 moves to the recovery position; the robotic arm picks up the material from the full material tray at the material picking position, and after all the material has been removed, the second motor of the lower lifting device 300 is activated, driving the second top plate to rise, so as to lift the empty material tray to the position of the first clamping plate assembly 400; the first clamping plate assembly 400 clamps the empty material tray. After the material tray is loaded, the second motor reverses its direction, driving the second top plate to descend, causing the lower lifting device 300 to exit the conveying path of the upper lifting device 200. Then, the drive assembly 520 actuates, returning the lower lifting device 300 to the loading position to load the next full material tray, while the upper lifting device 200 moves to below the first clamping assembly 400 to receive the empty material tray held by the first clamping assembly 400. Then, the drive assembly 520 actuates again, moving the upper lifting device 200 to the recovery position, while the lower lifting device 300, carrying the next full material tray, continues to return to the unloading position for loading by the machine. The robotic arm performs the material handling operation. After the upper lifting device 200 moves the empty material tray to the recycling position, the first motor 230 of the upper lifting device 200 is activated, driving the first top plate 210 to rise. During the rise of the first top plate 210, the empty material tray on the first top plate 210 will move upward through the opening 811 of the recycling frame 810 to pass over the lifting ramp 8222 of the carrier 822 and be carried on the bearing surface 8221 of the carrier 822. Through the continuous repetition of the above process, the empty material tray will gradually be stacked into the area defined by the two side guide components 830, realizing the recycling of the empty material tray.

[0077] It should be noted that, in this embodiment, both the first top plate 210 of the upper lifting device 200 and the second top plate of the lower lifting device 300 can be equipped with vacuum suction cups. These vacuum suction cups are used to fix the trays within the corresponding lifting devices, preventing the trays from slipping during the translational movement of the upper and lower lifting devices 200 and 300. When it is necessary to remove the tray from the corresponding lifting device, the vacuum suction cups can be released to ensure the trays can smoothly flow to the next process.

[0078] It should also be noted that in other embodiments, rollers can be installed at the bottom of the frame 100 so that the feeding and recycling equipment can be moved to the required position at any time, thereby improving the flexibility of the feeding and recycling equipment in this embodiment.

Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
