Description

Technical Field

[0001] This utility model relates to the field of battery module production technology, specifically to a truss handling device for destacking empty battery module trays. Background Technology

[0002] In power battery module and battery pack production lines, battery cells are typically transported to the production line in the form of multi-layer finished pallets. Then, robotic arms or grippers sort the cells sequentially onto the conveyor line for subsequent processes. Empty pallets require specialized destacking and stacking equipment to ensure the continuity and stability of the entire production process. Therefore, the destacking and stacking equipment is one of the primary components of a battery pack production line.

[0003] In existing technologies, common methods for empty pallet destacking and stacking mainly include truss-type and six-axis robot-type methods. Existing truss-type structures can meet the conventional pallet destacking and stacking needs and facilitate spatial layout to a certain extent. However, truss-type structures usually require robust structural supports, resulting in complex overall structures, space occupation, and high manufacturing costs. Utility Model Content

The specific technical solution is as follows: A truss handling device for destacking empty battery module trays includes: a support assembly connected to the ground, the support assembly forming a portal structure; a moving assembly connected to the portal structure, the free end of the moving assembly having lateral and vertical degrees of freedom, the free end being able to move the empty tray along a vertical moving surface; and a clamping assembly connected to the free end of the moving assembly, the clamping assembly forming a centering clamping mechanism to center and clamp the empty tray.

[0005] Preferably, it also includes a plurality of empty material tray conveyor lines for conveying empty material trays, a support component spanning a plurality of parallel empty material tray conveyor lines, and a movable component capable of moving the clamping component to empty material tray conveyor lines at different positions, so as to move the empty material tray to empty material tray conveyor lines at different positions.

[0007] Preferably, the moving component includes: mutually perpendicular gear and rack transmission members, the horizontally moving gear and rack transmission member having a lateral degree of freedom and the vertically moving gear and rack transmission member having a vertical degree of freedom, the gear and rack transmission members driving the movement trajectory of the clamping component to form a vertical moving surface; a transverse slide rail connected to a horizontal structure of the support component spanning the empty tray conveyor line, the horizontally moving gear and rack transmission member driving the clamping component to move laterally, thereby moving the clamping component to different positions on the empty tray conveyor line; and a vertical slide rail connected to the horizontally moving gear and rack transmission member, the vertically moving gear and rack transmission member driving the clamping component to move vertically, thereby clamping the empty tray located on the empty tray conveyor line.

[0008] Preferably, the gear and rack transmission components include meshing gears and racks, and the moving components also include felt gears that mesh with the racks. The felt gears are in communication with external lubricating oil to lubricate the racks.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] like Figure 1 As shown, this embodiment is a truss handling device for destacking empty battery module trays. The empty tray includes an empty pallet 5 for carrying battery modules and a base 6 for carrying the empty pallet 5. Specifically, the base 6 is a conventional plastic pallet with five layers of empty pallets 5 without battery modules placed on top. In this embodiment, during the handling of the empty pallets 5 or the base 6, only a single layer of empty pallets 5 is handled, or the base 6 and the bottommost empty pallet 5 are handled simultaneously.

[0018] like Figure 2 As shown, this embodiment includes: a support component 1 connected to the ground, the support component 1 forming a gate-shaped structure; a moving component 2 connected to the gate-shaped structure, the free end of the moving component 2 having lateral and vertical degrees of freedom, the free end being able to move the empty material tray along a vertical moving surface; and a clamping component 3 connected to the free end of the moving component 2, the clamping component 3 forming a centering clamping mechanism to center and clamp the empty material tray.

[0019] Specifically, in this embodiment, the X-axis direction is the relative movement direction of the centering clamping mechanism, the Y-axis direction is the lateral movement direction of the free end of the moving component 2, and the Z-axis direction is the vertical movement direction of the free end of the moving component 2.

[0020] Secondly, the cross-section of the gate-shaped structure is U-shaped. The bottom of the support component 1 is fixed to the ground with bolts. Its two sides are vertically arranged and parallel to the Z-axis, while its top is horizontally arranged and connected to the moving component 2, and parallel to the Y-axis. This simplifies the structure of the support component 1, and its footprint is only the contact area between the two sides and the ground, reducing the floor space. Secondly, the free end of the moving component 2 moves relative to the top of the support component 1 along the Y-axis or Z-axis. The vertical moving surface is parallel to the YZ plane. The clamping component 3 is fixedly connected to the free end of the moving component 2, and it clamps the empty material tray along the X-axis, allowing the clamping component 3 to move the empty material tray along the vertical moving surface. The free end of the moving component 2 drives the clamping component 3 to move along the vertical moving surface. The centering clamping mechanism of the clamping component 3 can be a symmetrically arranged gripper 34 cylinder to synchronously and relatively approach and clamp the empty pallet 5 or the base 6, or it can be a servo and bidirectional screw drive mechanism to synchronously and relatively approach and clamp the empty pallet 5 or the base 6. The moving ends of the centering clamping mechanism are symmetrically arranged, and they synchronously approach or move away from each other. The symmetry plane is the center plane of the moving end's moving trajectory. The center plane is perpendicular to the moving end's moving trajectory, and the symmetry plane is parallel to the vertical moving surface. In summary, this embodiment can complete the function of transporting the empty pallet 5 or the base 6, and has low structural complexity, small space occupation, and low manufacturing cost.

[0021] Furthermore, this embodiment also includes several empty material tray conveyor lines 4 for conveying empty material trays, a support component 1 spanning several parallel empty material tray conveyor lines 4, and a moving component 2 capable of moving the clamping component 3 to different positions of the empty material tray conveyor lines 4 to move the empty material tray to different positions of the empty material tray conveyor lines 4.

[0022] Specifically, the empty pallet conveyor line 4 is a conventional conveyor line. The figure only shows its position, and its specific structure is a conventional structure, which will not be described in detail here. Secondly, this embodiment includes two empty pallet conveyor lines 4. One is used to convey an empty pallet composed of multiple empty pallets 5 and a base 6. The other is used to convey the empty pallet 5 and the base 6 after the empty pallet has been disassembled. Both empty pallet conveyor lines 4 intersect with the vertical moving plane and the plane of symmetry. The conveying direction of both is perpendicular to the vertical moving plane and the plane of symmetry. Both pass through the gate structure of the support component 1, so that the moving component 2 can drive the clamping component 3 to contact the two empty pallet conveyor lines 4. The empty pallet conveyor line 4 moves the empty pallet to the working range of the centering clamping mechanism of the clamping component 3, so that it can clamp the single-layer empty pallet 5 or the single-layer empty pallet 5 and the base 6 on the empty pallet conveyor line 4. The moving component 2 can move the clamping component 3 after clamping to another empty pallet conveyor line 4, thereby completing the destacking of the empty pallet.

[0023] Furthermore, the arrangement direction of the empty material tray conveyor line 4 is perpendicular to the conveying direction of the empty material tray conveyor line 4; the support component 1 includes parallel and vertically arranged columns 11, the top of the columns 11 is connected to a horizontally arranged crossbeam 12, the crossbeam 12 is connected to the moving component 2, the length direction of the crossbeam 12 is consistent with the arrangement direction of the empty material tray conveyor line 4, and the projection of the crossbeam 12 along the vertical direction is perpendicular to the conveying direction of the empty material tray conveyor line 4.

[0024] Specifically, the empty pallet conveyor line 4 is arranged along the Y-axis, and its conveying direction and length direction are both along the X-axis. Secondly, the support component 1 includes two columns 11, whose bottom ends are fixed to the ground with bolts to ensure their stability, and whose top ends are fixed to both ends of the crossbeam 12 with bolts to ensure the stability of the crossbeam 12. The crossbeam 12 is fixedly connected to the moving component 2 to ensure the moving stability of the moving component 2. The moving component 2 is fixedly connected to the clamping component 3 to ensure the clamping stability of the clamping component 3, thus ensuring that the clamping component 3 can stably transport the empty pallet 5 or the bottom support 6. Furthermore, the length direction of the crossbeam 12 is along the X-axis, which is perpendicular to the length direction of the empty pallet conveyor line 4. Its projection along the Z-axis intersects with the empty pallet conveyor line 4, so that when the moving component 2 drives the clamping component 3 along the crossbeam 12, the clamping component 3 can contact the empty pallet conveyor line 4 to complete destacking and transport.

[0025] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the moving component 2 includes: mutually perpendicular gear and rack transmission members 21, the horizontally moving gear and rack transmission member 21 having lateral degree of freedom, the vertically moving gear and rack transmission member 21 having vertical degree of freedom, the gear and rack transmission member 21 driving the moving trajectory of the clamping component 3 to form a vertical moving surface; a transverse slide rail 22 connected to the horizontal structure of the support component 1 spanning the empty material tray conveyor line 4, the horizontally moving gear and rack transmission member 21 driving the clamping component 3 to move laterally, so as to move the clamping component 3 to different positions of the empty material tray conveyor line 4; and a vertical slide rail 23 connected to the horizontally moving gear and rack transmission member 21, the vertically moving gear and rack transmission member 21 driving the clamping component 3 to move vertically, so as to clamp the empty material tray located on the empty material tray conveyor line 4.

[0026] Specifically, the gear and rack transmission component 21 is a conventional transmission mechanism, consisting of a servo motor, gears, and a rack. Secondly, the horizontal structure of the support assembly 1 spanning the empty material tray conveyor line 4 is a crossbeam 12. The horizontally moving gear and rack transmission component 21 is fixedly connected to the crossbeam 12, and the transverse slide rail 22 is also fixedly connected to the crossbeam 12, with both having a length direction along the Y-axis. The servo motor moves along the horizontally fixed rack via the gears, while simultaneously sliding along the transverse slide rail 22, thereby moving along the Y-axis to clamp the assembly 3 and the vertically moving gear and rack transmission component 21. The vertically arranged gear... The length direction of the bar and the vertical slide rail 23 is both along the Z-axis and are fixedly connected to the support component 1. The gear and rack transmission component 21, which moves relatively horizontally, moves vertically. Another servo motor drives the vertically set rack to move along the Z-axis through the gear. At the same time, the vertical slide rail 23 slides relative to the servo motor, thereby moving the clamping component 3 along the Z-axis. This allows the clamping component 3 to clamp the empty pallet 5 or bottom support 6 placed on the empty pallet conveyor line 4 along the Z-axis, and it can move the empty pallet 5 or bottom support 6 along the Y-axis to another empty pallet conveyor line 4, realizing the destacking process of the empty pallet.

[0027] Furthermore, the moving component 2 also includes a felt gear 24 that meshes with the rack, the felt gear 24 being in communication with external lubricating oil to lubricate the rack.

[0028] Specifically, the felt gear 24 is a gear made of wool felt, which has good oil absorption and cleaning properties. External lubricating oil is injected into the felt gear 24 through the oil pipe, so that it is wetted with lubricating oil. When it moves relative to the rack, the lubricating oil is applied to the rack through the gear teeth, and then the lubricating oil enters the interior of the gear and rack transmission component 21 to achieve the lubrication effect. Secondly, during the rotation process, the felt gear 24 can absorb and remove iron filings and dirt on the rack, play a cleaning role, and prevent rack wear.

[0029] like Figure 7 and Figure 8As shown, the clamping assembly 3 includes a mounting frame 32 connected to the free end of the moving assembly 2 with a vertical degree of freedom. The clamping mechanism is symmetrically arranged at one end of the mounting frame 32 near the empty material tray, and the plane of symmetry is parallel to the vertical moving plane. Each clamping mechanism includes a clamping slide rail 31 and a clamping cylinder 35 connected to the mounting frame 32. The length direction of the clamping slide rail 31 is consistent with the extension and retraction direction of the clamping cylinder 35. The extension and retraction end of the clamping cylinder 35 is connected to the mounting plate 33. The mounting plate 33 slides relative to the clamping slide rail 31. Both ends of the mounting plate 33 are connected to grippers 34. The ends of the grippers 34 away from the mounting plate 33 are connected to spring compression shafts 36. The extension and retraction direction of the spring compression shafts 36 is consistent with the extension and retraction direction of the clamping cylinders 35.

[0030] Specifically, the mounting frame 32 is welded from steel pipes, and its top end is fixedly connected to the vertically moving gear and rack transmission component 21 by bolts, enabling it to drive the mounting frame 32 to move up and down along the Z-axis. Secondly, the bottom end of the mounting frame 32 is fixedly connected to two clamping mechanisms by bolts. The clamping mechanisms move synchronously relative to each other along the X-axis, with their symmetry plane being the center plane of the movement trajectory, parallel to the YZ plane. Thirdly, the clamping cylinder 35 is fixedly connected to the mounting frame 32 by bolts, and the parallel clamping slide rail 31 is fixedly connected to the mounting frame 32, with its length direction being the X-axis. The mounting plate 33 is connected to the clamping slide rail. 31 forms a sliding connection and is connected to the telescopic end of the clamping cylinder 35. Both ends of the mounting plate 33 are fixedly connected to the grippers 34, so that the clamping cylinder 35 can push the grippers 34 to move relative to each other or away from each other along the clamping slide rail 31. When the grippers 34 are in the initial position, the spacing between the symmetrically arranged grippers 34 is the largest. At this time, the projection of the clamping area enclosed by the four grippers 34 along the Z-axis can wrap the empty material tray. When the grippers 34 move down and move relative to each other, they can clamp a single empty tray 5 to another empty material tray conveyor line 4, or clamp a single empty tray 5 and the bottom support 6 to another empty material tray conveyor line 4, so as to realize the destacking process.

[0031] Secondly, the end of the gripper 34 away from the mounting plate 33 is connected to a spring compression shaft 36, which includes a sliding shaft and a compression spring. When the gripper 34 grips the empty tray 5, the compression spring is compressed, and the shaft slides along the X-axis relative to the end of the gripper 34. When the gripper 34 continues to move downward until the end of the gripper 34 is below the base 6, the compression spring loses pressure, and the shaft returns to its initial position under the action of the elastic force. Then, one end of the shaft moves to the bottom of the base 6, so that it can provide upward support for the base 6, so as to avoid deformation of the base 6 during the lifting and lowering process, which would cause the gripper 34 to lose its gripping effect on the base 6 and cause the base 6 to fall.

[0032] Furthermore, this embodiment also includes a support shaft 7 that is detachably connected to the support assembly 1. The support shaft 7 can restrict the free end of the movable assembly 2 from vertically moving relative to the support assembly 1. Specifically, during maintenance, the support shaft 7 is placed between the vertically moving gear and rack transmission component 21 and the crossbeam 12, preventing the vertically moving gear and rack transmission component 21 from moving vertically relative to the crossbeam 12, thereby ensuring that the operator can install, maintain, or repair the mechanical structure.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
