[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Please refer to Figures 1-4 This application provides an automatic material handling device, comprising: Support frame 1, on which a liftable support component is installed, the support component is used to place material rack 2, and multiple material trays 3 are arranged at intervals on the material rack 2; The telescopic component includes a telescopic tray support 5, which has a first station and a second station. When placed at the first station, the tray support 5 extends into the material rack 2 to support the tray 3. When placed at the second station, the tray support 5 moves the tray 3 out of the material rack 2. A positioning component is provided corresponding to the second workstation and is used to lift the material tray 3 and position the material tray 3.

[0021] Specifically, the rack 2 is equipped with multiple brackets to support trays 3, on which multiple batteries 4 can be placed. After the trays 3 are filled on the rack 2, the multiple trays 3 are arranged at intervals along the height direction of the rack 2. The automatic loading and unloading device provided in this embodiment is applied to the battery testing process. The loading and unloading of batteries in the battery testing process are both realized by AGV. Loading refers to the AGV placing the rack 2 filled with trays 3 onto the support component, and unloading refers to the AGV removing the rack 2 from the support component.

[0022] The support component, as the main component supporting the material rack 2, is mounted on the support frame and can be raised and lowered vertically to facilitate loading and unloading by the AGV. The telescopic component and the positioning component are mounted on the base plate. The telescopic component includes a freely retractable tray handle 5, used for picking up and placing the tray 3. The tray handle 5 has a first station and a second station at its two ends of its travel. The tray handle 5 switches between the first and second stations to pick up and place materials into the material rack 2. During picking up, the telescopic component drives the tray handle 5 to extend into the material rack 2 and into the first station. The support component then raises and lowers the material rack 2, causing the tray 3 to fall onto the tray handle 5. The telescopic component then drives the tray handle 5 back to the second station. The positioning component then positions the tray 3 to facilitate subsequent gripping of the batteries within the tray by the robotic arm. When feeding material, the material tray support 5 removes the material tray 3 from the positioning component at the second station. Then, the telescopic component drives the material tray support 5 to extend into the material rack 2 and place it in the first station. With the help of the support component, the material rack 2 is raised and lowered to put the material tray 3 back onto the material rack 2.

[0023] Furthermore, the telescopic component includes: Support plate 6 is provided on one side of support frame 1. A positioning seat 7 is fixed at the end of support plate 6 away from support frame 1. A first driving device 8 is installed on the positioning seat 7. The first driving device 8 is connected to a transmission screw 9. The transmission screw 9 extends along a first direction, which is parallel to the top surface of support plate 6. The first slide rail 10 is mounted on the top surface of the support plate 6. A first slider 11 is slidably mounted on the first slide rail 10. The first slider 11 is sleeved on the transmission screw 9 and threadedly connected to the transmission screw 9. The first slider 11 is connected to the material tray handle 5.

[0024] Specifically, in this embodiment, the first direction is horizontal. The support plate 6 is generally flat and is located on the side of the support frame 1 away from the AGV loading / unloading direction, and is fixedly installed on the base plate. It provides a stable mounting carrier for other components of the telescopic assembly. Its extension direction is consistent with the telescopic direction of the tray handle 5. A positioning seat 7 is fixedly installed at the end away from the support frame 1. The structure of the positioning seat 7 is adapted to the installation requirements of the first drive device 8, and is used to stably fix the first drive device 8, so that the output shaft axis of the first drive device 8 is coaxial with the axis of the transmission screw 9, avoiding transmission errors. The first drive device 8 and the transmission screw 9 are connected by a coupling. The transmission screw 9 extends along the horizontal first direction, and the end near the first drive device 8 is rotatably connected to the positioning seat 7. In this embodiment, the first drive device 8 is a motor.

[0025] A first slide rail 10 is laid on the top surface of the support plate 6 along a first direction. The extension trajectory of the first slide rail 10 is parallel to the transmission screw 9. The first slider 11 is slidably assembled on the first slide rail 10 and can slide along the first slide rail 10. At the same time, the first slider 11 is also threadedly connected to the transmission screw 9. When the first driving device 8 drives the transmission screw 9 to rotate, the threaded transmission converts the rotational motion into linear motion of the first slider 11 along the first slide rail 10. The first slider 11 is directly connected to the material tray holder 5, thereby driving the material tray holder 5 to move synchronously, realizing the switching of the material tray holder 5 between the first station and the second station.

[0026] Furthermore, a limiting seat 12 is fixed to one end of the support plate 6 near the support frame 1. A bearing sleeve is provided on the limiting seat 12, and the bearing sleeve is connected to the end of the transmission screw 9 away from the first driving device 8.

[0027] Specifically, the limiting seat 12 has a block-like structure and is fixedly installed on the end of the support plate 6 near the support frame 1. It is symmetrically distributed along the first direction with the positioning seat 7 at the end of the support plate 6 away from the support frame 1, forming support for both ends of the transmission screw 9. Simultaneously, the limiting seat 12 can also limit the movement distance of the first slider 11 towards the support frame 1, assisting in positioning the first slider 11 at the first work position. A hole for mounting a bearing sleeve is provided at the center of the limiting seat 12. The axis of this hole is coaxial with the axis of the output shaft of the first drive device 8 on the positioning seat 7. The bearing sleeve is fitted into the hole of the limiting seat 12, and its inner side forms a rotational fit with the end of the transmission screw 9 away from the first drive device 8.

[0028] Furthermore, the tray handle 5 is provided with multiple hollow positions 13, the tray handle 5 is provided with an air passage, and the top surface of the tray handle 5 is provided with multiple vacuum nozzles 14 that communicate with the air passage.

[0029] Specifically, the material tray support 5 has a frame structure that is adapted to the shape of the material tray 3. Multiple hollow positions 13 are set at intervals along the length and width of its top surface. The hollow positions 13 not only reduce the weight of the material tray support 5 itself and reduce the load on the telescopic component during transmission, but also prevent the airflow from being stuck due to the top surface of the material tray support 5 being completely in contact with the bottom surface of the material tray 3, thus reserving an airflow channel for the suction action of the vacuum nozzle 14.

[0030] The tray support 5 has a sealed air passage machined inside along the frame. One end of the air passage is connected to an external vacuum pump via an air pipe, and the other end is connected to multiple vacuum nozzles 14 on the top surface of the tray support 5. The vacuum nozzles 14 are evenly distributed on the edge and center of the top surface of the tray support 5, and their opening height is slightly higher than the top surface of the tray support 5, ensuring that the vacuum nozzles 14 can make close contact with the bottom surface of the tray 3 after the tray 3 is placed in the tray support 5.

[0031] Furthermore, the positioning component includes: A pair of positioning plates 15 are arranged along a second direction and respectively disposed on both sides of the support plate 6. The second direction is parallel to the top surface of the support plate 6 and perpendicular to the first direction. The edge of the positioning plate 15 away from the support frame 1 is provided with a positioning baffle 16. The positioning plate 15 is sleeved on the guide post 17, which extends along a third direction and is perpendicular to the top surface of the support plate 6. The second drive device 18 is connected to a lifting rod 19, which is located below the positioning plate 15. The second drive device 18 is used to drive the lifting rod 19 to rise and fall.

[0032] Specifically, in this embodiment, the second direction is horizontal and the third direction is vertical. Two positioning plates 15 are provided, symmetrically arranged on both sides of the support plate 6. The top surfaces of the two positioning plates 15 are flush, together forming the support surface for the material tray 3. Vertically upward-extending positioning baffles 16 are provided on the edges of both positioning plates 15 away from the support frame 1 and on the edges of the sides that are far from each other. When the material tray handle 5 moves the material tray 3 towards the positioning plate 15, the positioning baffles 16 can limit the movement of the material tray 3.

[0033] Each positioning plate 15 has two through holes for fitting guide posts 17. The guide posts 17 are fixedly mounted on the base plate in the vertical direction, and the positioning plate 15 is fitted onto the guide posts 17 through the through holes to form a sliding fit. When the positioning plate 15 is raised or lowered, the guide posts 17 can limit the horizontal displacement of the positioning plate 15, ensuring that it always moves smoothly in the vertical direction, and avoiding the material tray 3 from slipping due to tilting or affecting the accuracy of the subsequent robot arm's gripping of the battery.

[0034] The second drive unit 18 is installed on the equipment base below the positioning plate 15. Its output end is fixedly connected to the lifting rod 19, which extends vertically and whose top end contacts the positioning plate 15. When the telescopic assembly moves the tray support 5 to transfer the tray 3 to the second work station, the second drive unit 18 is activated, driving the lifting rod 19 to extend upward. The lifting rod 19 pushes the positioning plate 15 upward along the guide column 17 until the top surface of the positioning plate 15 contacts the bottom surface of the tray 3 and lifts the tray 3 off the tray support 5. At this time, the two sides of the tray 3 are limited by the positioning baffles 16 on the edge of the positioning plate 15, and the bottom is stably supported by the positioning plate 15, achieving precise positioning. Optionally, the second drive unit 18 is a cylinder.

[0035] Furthermore, a first movable plate 20 is provided on the side of the positioning plate 15 near the support frame 1. The first movable plate 20 is connected to the positioning plate 15 through a third driving device 21, which is used to drive the first movable plate 20 to move along the first direction. A second movable plate 33 is provided on the side of one of the positioning plates 15 away from the other positioning plate 15. The second movable plate 33 is connected to the positioning plate 15 through a seventh driving device 34, which is used to drive the second movable plate 33 to move along the second direction.

[0036] Specifically, the first movable plate 20 is generally elongated and is located at one end of the positioning plate 15 near the support frame 1. It is used to position the tray 3 in the first direction when it is placed on the positioning plate 15. The third drive device 21 is fixedly installed on the side of the positioning plate 15, and its output end extends along the first direction and is fixedly connected to the end of the first movable plate 20, which can drive the first movable plate 20 to reciprocate along the first direction. The second movable plate 33 is generally elongated and is located on one side of one of the positioning plates 15. It is used to position the tray 3 in the second direction when it is placed on the positioning plate 15. The seventh drive device 34 is fixedly installed at the bottom of the positioning plate 15, and its output end extends along the second direction and is fixedly connected to the end of the second movable plate 33, which can drive the second movable plate 33 to reciprocate along the second direction.

[0037] When the second drive device 18 lifts the positioning plate 15 by lifting the lifting rod 19 and lifts the tray 3 off the tray handle 5, the positioning baffle 16 limits the tray 3 on the side away from the support frame 1. At this time, the third drive device 21 and the seventh drive device 34 are activated. The first movable plate 20 moves closer to the tray 3 in the first direction, and the second movable plate 33 moves closer to the tray 3 in the second direction until the sides of the first movable plate 20 and the second movable plate 33 are tightly fitted with the edge of the tray 3, so that the tray 3 is positioned in the first direction and the second direction, avoiding inaccurate positioning due to the size deviation of the tray 3 itself or slight displacement during the transfer process.

[0038] After all the batteries in the tray 3 on the positioning plate 15 have been removed, the tray 3 on the positioning plate 15 is removed to make room for the subsequent tray 3. The removal of the tray 3 can be done manually or through its tray removal mechanism.

[0039] Furthermore, the positioning plate 15 is provided with a first laser sensor 22 for detecting whether the material tray 3 is placed on the positioning plate 15.

[0040] Specifically, the first laser sensor 22 is fixedly installed at the bottom of one of the positioning plates 15, with its transmitting and receiving ends arranged vertically. When the tray holder 5 transfers the tray 3 to the second station, the laser beam emitted by the transmitting end of the first laser sensor 22 is reflected by the tray 3 and received by the receiving end, thus indicating that a tray 3 is placed at the second station, which can be used to instruct the subsequent robotic arm to grasp the battery 4.

[0041] Furthermore, the support plate 6 is provided with second laser sensors 23 on both sides near the support frame 1, for detecting whether the material tray 3 is placed on the material rack 2.

[0042] Specifically, two second laser sensors 23 are provided, respectively fixedly installed on both sides of the support plate 6 near the support frame 1. The installation height of the two sensors is adapted to the placement height of the material tray 3 on the material rack 2. The emitting end and receiving end of the first laser sensor 23 are both tilted towards the material tray 3 inside the material rack 2 on the supporting assembly. The second laser sensor 23 is used to detect whether a material tray 3 is placed at the position where the material tray handle 5 picks up material on the material rack 2. It is used to instruct the supporting assembly to lift and lower when the material tray handle 5 picks up or puts down material in the material rack 2, so as to ensure that the corresponding layer of the material rack 2 has a tray 3 when the material tray handle 5 picks up material, or that the corresponding layer of the material rack 2 is empty when the material tray handle 5 puts down material. The specific control logic is not described here.

[0043] Furthermore, the support component includes: The second slide rail 24 is mounted on the support frame 1 and extends along the third direction. A fourth drive device 25 is mounted on the top of the second slide rail 24. The second slider 26 is slidably mounted on the second slide rail 24 and is connected to the fourth drive device 25. A support frame 27 is mounted on the second slider 26. Two conveyor belts 28 are arranged on the support frame 27 along the second direction. The conveyor belts 28 are used to support the material rack 2 and can drive the material rack 2 to move along the first direction.

[0044] Specifically, the second slide rail 24 is fixedly installed on the side of the support frame 1 along a third direction, and its extension length is adapted to the maximum lifting stroke of the material rack 2, providing a stable guide trajectory for the movement of the second slider 26. The fourth drive device 25 is fixedly installed on the top of the second slide rail 24, and its output end is connected to the second slider 26 through a transmission mechanism such as a lead screw. The second slider 26 is slidably mounted on the second slide rail 24 and can be vertically lifted and lowered along the second slide rail 24 under the drive of the fourth drive device 25, ensuring no lateral deviation during the lifting process.

[0045] The second slider 26 is fixedly connected to the support frame 27 on the side away from the second slide rail 24. The support frame 27 has a frame structure, and two conveyor belts 28 are installed at intervals along the second direction on its top surface. The top surfaces of the two conveyor belts 28 are kept flush and together form the bearing surface of the material rack 2. The two conveyor belts 28 are driven by a fifth drive device 31 and a synchronous shaft. The fifth drive device 31 is a motor.

[0046] When the AGV places the rack 2 on the conveyor belt 28, the rack is placed at the outer end of the conveyor belt 28, and then the conveyor belt 28 drives the rack 2 to move to the inner end to facilitate the telescopic component to pick up the material; after the tray 3 on the rack 2 is taken out, the conveyor belt 28 moves the empty rack 2 to the outer end again so that the AGV can take away the empty rack 2.

[0047] Furthermore, a first guide plate 29 is fixed on the side of the conveyor belt 28 away from the second slide rail 24, and a second guide plate 30 is movably installed on the side of the conveyor belt 28 close to the second slide rail 24. The second guide plate 30 is movable along the second direction.

[0048] Specifically, the first guide plate 29 is in the shape of a long strip and is vertically fixed to the edge of the conveyor belt 28 on the side away from the second slide rail 24. Its length is adapted to the length of the conveyor belt 28. When the material rack 2 is placed on the conveyor belt 28, the inner sidewall of the first guide plate 29 can guide the conveying of the material rack 2, thereby limiting the conveying direction of the material rack 2.

[0049] The second guide plate 30 is also a long strip, parallel to the first guide plate 29, and is movably installed on the edge of the conveyor belt 28 near the second slide rail 24. Its length is the same as the first guide plate 29, and it is used to guide the movement of the material rack 2 in cooperation with the first guide plate 29. The second guide plate 30 is connected to the second slider 24 through the sixth drive device 32. The sixth drive device 32 can drive the second guide plate 30 to move along the second direction, thereby adapting to the guiding requirements of material racks 2 of different sizes or stabilizing the material rack 2 during the lifting and lowering of the second slider 26.
