[0040] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0043] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components.

[0044] Furthermore, the terms "first," "second," and the like are primarily used to distinguish between different devices, elements, or components, which may or may not have the same specific type and configuration, and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0045] As mentioned in the background technology, in the related art, in order to prevent the battery cells from colliding with the stopping structure, a support portion is usually provided at the top of the stopping structure in the vertical direction to support a flexible belt so that the battery cells do not come into contact with hard objects on the carrier. However, the support portion easily affects the removal and placement of the battery cells, making the removal and placement of the battery cells difficult.

[0046] In order to solve the above problems, the present application provides a transfer device and battery production equipment. In the vertical direction, the height of the support member on the transfer device for supporting the flexible belt is lower than the height of the carrying surface, so that during the removal and placement process, the battery cell will not be hindered by the support member and can enter or leave the carrying surface more smoothly, thereby facilitating the removal and placement of the battery cell and reducing the difficulty of transferring the battery cell during the battery production process.

[0047] The technical solution of the present application will be further described below with reference to specific embodiments and drawings.

[0048] See also Figures 1 to 4The present embodiment provides a transfer device 1, which includes: a carrier 100, a lifting drive structure 200, a stopping structure 300 and an anti-collision structure 400. The carrier 100 includes a carrying surface 110, which is used to carry the object to be transferred; the lifting drive structure 200 is connected to the carrier 100, and is used to drive the carrier 100 to move up and down; the stopping structure 300 is arranged around the carrier 100, and is used to stop the object to be transferred carried on the carrying surface 110 in a first direction to prevent the object to be transferred from leaving the carrier along the first direction. The load-bearing surface 110, the first direction is parallel to the load-bearing surface 110; along the first direction, the anti-collision structure 400 is arranged between the load-bearing member 100 and the stopping structure 300, the anti-collision structure 400 includes a flexible belt 410 and a support member 420, the two ends of the flexible belt 410 along the vertical direction are respectively fixed on the stopping structure 300, the support member 420 is arranged on the stopping structure 300, and is used to support the flexible belt 410, so that a gap is formed between the flexible belt 410 and the stopping structure 300, and along the vertical direction, the height of the support member 420 is lower than the height of the load-bearing surface 110.

[0049] In this embodiment, the component to be transferred is a battery cell as an example for description.

[0050] It should be noted that the first direction can be Figure 1 The direction indicated by the arrow X can also be the direction indicated by the arrow Y, or any direction between the arrow X and the arrow Y. The vertical direction is Figure 1 The direction indicated by the arrow Z.

[0051] When it is necessary to use the transfer device 1 to transfer the battery cell, the battery cell is carried on the carrying surface 110 of the carrier 100, and the lifting drive structure 200 drives the carrier 100 to rise in the vertical direction to drive the battery cell to rise in the vertical direction. During this process, since the blocking structure 300 is arranged around the carrier 100 and blocks the battery cell carried on the carrying surface 110 in the first direction, the blocking device can limit the battery cell to the carrying surface 110 to prevent the battery cell from leaving the carrying surface 110 along the first direction, and an anti-collision structure 400 is provided between the blocking structure 300 and the carrier structure. The anti-collision structure 400 includes a support member 420 and a flexible belt 410. The flexible belt 410 has two vertical directions. The ends are respectively fixed on the stopping structure 300, and the support member 420 is arranged on the stopping structure 300 and is used to support the flexible belt 410 so that a gap is formed between the flexible belt 410 and the stopping structure 300. When the battery cell contacts the stopping structure 300 due to inertia during movement, the flexible belt 410 can absorb the impact force and protect the surface of the battery cell from damage, thereby improving the quality and pass rate of the product. In addition, in the vertical direction, the height of the support member 420 is lower than the height of the carrying surface 110, so that during the removal and placement process, the battery cell will not be hindered by the support member 420 and can enter or leave the carrying surface 110 more smoothly, thereby facilitating the removal and placement of the battery cell and reducing the difficulty of transferring the battery cell during the battery production process.

[0052] In one possible embodiment, participating Figures 2 to 4 , along the vertical direction, the support member 420 is slidably disposed on the blocking structure 300 and is fixedly connected to the carrier 100 .

[0053] Since the support member 420 is slidingly arranged on the stopping structure 300 and is fixedly connected to the carrier 100, when the carrier 100 is lifted and lowered under the action of the lifting drive structure 200, the support member 420 can slide synchronously with it, thereby ensuring that the relative position between the flexible belt 410 and the carrier 100 always remains stable, ensuring the anti-collision effect. For example, in the operation of frequently lifting and lowering the carrier 100, the support member 420 and the carrier 100 will not move out of sync, thereby affecting the anti-collision and pick-and-place effects.

[0054] For example, the support member 420 is fixedly connected to the carrier 100 via a connecting member 430 .

[0055] In one possible embodiment, see Figure 2 and Figure 3 A guide slot 310 is provided on the blocking structure 300 , and the guide slot 310 extends in a vertical direction. A guide slider that slides with the guide slot 310 is provided on the support member 420 .

[0056] Therefore, the cooperation between the guide groove 310 and the guide slider can ensure that the support member 420 performs precise linear motion in the vertical direction, avoiding the possible offset, jamming or skew of the support member 420 during the lifting process, thereby ensuring the stability and reliability of the operation of the entire device. For example, during long-term frequent lifting operations, the support member 420 can always be kept moving along the established vertical path, and the support and protection effect of the transfer member will not be affected by deviation. Moreover, this sliding cooperation method can effectively reduce the friction resistance between the support member 420 and the stopping structure 300, making the lifting and lowering of the support member 420 smoother, reducing the energy consumption required to drive the carrier 100 to lift and lower, and improving energy utilization efficiency. In addition, the cooperation between the guide groove 310 and the guide slider increases the contact area and connection strength between the support member 420 and the stopping structure 300, so that the entire structure can better disperse stress when bearing the weight of the transfer member and external force, reducing the risk of local deformation and damage.

[0057] In one possible embodiment, see Figures 5 to 8 An upper stop 120 and a lower stop 130 are provided on the carrier 100; the lifting drive structure 200 includes a lifting drive member 210 and a driving connecting rod 220, one end of the driving connecting rod 220 is connected to the lifting drive member 210, and a clamping portion 2201 is provided on the other end of the driving connecting rod 220, and the clamping portion 2201 is clamped between the upper stop 120 and the lower stop 130.

[0058] The lifting drive 210 may be a linear motor, a worm gear lift, a crank slider mechanism, an electro-hydraulic servo cylinder, or any other form of drive, which is not limited here.

[0059] By arranging an upper stop portion 120 and a lower stop portion 130 on the carrier 100, the clamping portion 2201 of the driving connecting rod 220 in the lifting drive structure 200 is clamped between the upper stop portion 120 and the lower stop portion 130. The cooperation between the clamping portion 2201 and the upper stop portion 120 and the lower stop portion 130 increases the connection stability between the lifting drive structure 200 and the carrier 100. During the process of the carrier 100 being lifted and lowered in the vertical direction, the shaking and vibration of the carrier 100 can be effectively reduced, thereby improving the operating stability of the entire transfer device 1.

[0060] In one possible embodiment, see Figures 6 to 8The clamping portion 2201 protrudes from the outer peripheral wall of the driving connecting rod 220 along the radial direction of the driving connecting rod 220; a clamping space 140 is opened on the carrier 100, and the top wall of the clamping space 140 forms an upper stop portion 120, and the bottom wall of the clamping space 140 forms a lower stop portion 130. An avoidance position is opened on the lower stop portion 130, and the avoidance position is used for the clamping portion 2201 to enter the clamping space 140, and along the vertical direction, the depth of the clamping space 140 matches the thickness of the clamping portion 2201.

[0061] It should be noted that the above-mentioned clamping portion 2201 can be a clamping key provided on the driving connecting rod 220, or the clamping portion 2201 can be directly processed on the driving connecting rod 220, which is not limited here.

[0062] Therefore, when the supporting member 100 needs to be raised in the vertical direction, the driving member drives the connecting rod 220 to move in the vertical direction toward the supporting member 100, and makes the clamping part 2201 pass through the avoidance position on the lower stop part 130 and enter the clamping space 140. Since the depth of the clamping space 140 matches the thickness of the clamping part 2201, the clamping part 2201 can be accurately positioned in the clamping space 140, so that during the lifting process, the clamping part 2201 can move stably in the clamping space 140 without shaking or deviating from the left and right, thereby ensuring the accuracy and stability of the supporting member 100 during the rising process.

[0063] Of course, the upper stopper 120 and the lower stopper 130 are not limited to the above structure. The carrier 100 may also be in the form of a flat plate, with its four corners extending upward to form side panels. An upper stopper 120 is provided on the inner side of the top of the two opposite side panels, which is a horizontally inwardly extending convex block, and a lower stopper 130 is provided at the corresponding position on the inner side of the bottom of the side panel, which is also a horizontally inwardly extending convex block. An annular clamping portion 2201 is processed on the end of the lifting drive rod, and the outer diameter of the clamping portion 2201 is larger than the outer diameter of the drive connection The diameter of the rod 220 can also be that the carrier 100 is a rectangular frame, and the upper stop parts 120 are respectively provided at the four corners on the inner side of the top of the frame, which are short columns vertically downward, and the lower stop parts 130 are provided at the corresponding positions on the inner side of the bottom of the frame, which are also short columns vertically upward. The driving connecting rod 220 is a square rod, and a square clamping part 2201 is welded at its end. The size of the clamping part 2201 is larger than the driving connecting rod 220, and is located between the upper stop part 120 and the lower stop part 130.

[0064] In one possible embodiment, see Figure 8 A snap-fit ​​key is provided on the end surface of the driving connecting rod 220 facing the carrier 100 , and at least one end of the snap-fit ​​key protrudes from the outer peripheral wall of the driving connecting rod 220 along the radial direction of the driving connecting rod 220 to form a snap-fit ​​portion 2201 .

[0065] By providing a separate snap-in key to form the snap-in portion 2201, the manufacturing process is simpler, reducing manufacturing difficulty and cost, and improving production efficiency, compared to the related art method of directly machining a complex snap-in structure on the drive connecting rod 220. For example, the snap-in key can be manufactured using standardized processes and molds, eliminating the need for complex cutting or forming of the drive connecting rod 220. Furthermore, snap-in keys of different sizes, shapes, and materials can be selected based on different load requirements and working conditions, thereby flexibly adjusting the performance and characteristics of the snap-in portion 2201. For example, when carrying a heavier part to be transferred, a stronger and larger snap-in key can be selected to enhance the snap-in effect and stability. Furthermore, the snap-in key can be individually precision-machined and tested before assembly to ensure the accuracy of its size and shape, thereby improving the assembly accuracy of the entire snap-in structure. For example, in applications where high assembly precision is required, a carefully manufactured snap-in key can better ensure the precise fit between the snap-in portion 2201 and the snap-in space 140 on the carrier 100.

[0066] In one possible embodiment, see Figure 8 Both ends of the snap-in key protrude from the outer peripheral wall of the driving connecting rod 220 .

[0067] Both ends of the snap-in key protrude from the outer peripheral wall of the drive connecting rod 220, so that during the snap-in process, both ends of the snap-in key can withstand the force from the carrier 100, making the force more evenly balanced, helping to reduce wear or deformation caused by excessive force on one side of the snap-in key, and extending the service life of the snap-in key. For example, when the carrier 100 is subjected to external forces from different directions, the snap-in keys protruding at both ends can evenly share these forces to ensure the stability of the snap-in. Moreover, the protrusions at both ends increase the contact area and snap-in points with the carrier 100, thereby improving the stability of the snap-in. Even when subjected to large vibrations or impacts, the snap-in portion 2201 can be more effectively prevented from slipping out of the snap-in space 140. In addition, since both ends of the snap-in key can play a positioning role, the relative position between the drive connecting rod 220 and the carrier 100 can be more accurately limited, further improving the positioning accuracy of the carrier 100 during the lifting process.

[0068] In one possible embodiment, see Figure 1 The blocking structure 300 includes a plurality of blocking bars 320 extending in a vertical direction, and the plurality of blocking bars 320 are arranged at intervals along the circumference of the bearing surface 110 .

[0069] Therefore, multiple baffles 320 are arranged at intervals along the circumference of the bearing surface 110, which can block and protect the parts to be transferred from various angles, prevent the parts to be transferred from accidentally detaching from the bearing surface 110 from different angles, and provide all-round protection. In addition, the intervals between the baffles 320 enable operators or detection equipment to more conveniently observe the status of the parts to be transferred on the bearing surface 110, discover problems in time and deal with them. Compared with the whole blocking structure 300, multiple baffles 320 arranged at intervals can reduce the weight of the entire blocking structure 300 while ensuring the protection effect, saving material costs.

[0070] In one possible embodiment, see Figure 1 , the bearing surface 110 is a rectangular bearing surface 110; the blocking structure 300 includes four groups of blocking bars 320, and the four groups of blocking bars 320 are respectively arranged at the four corners of the rectangular bearing surface 110, each group of blocking bars 320 includes two blocking bars 320, and the two blocking bars 320 in the same group of blocking bars 320 are respectively arranged close to two adjacent edges of the rectangular bearing surface 110.

[0071] The four groups of baffles 320 are respectively arranged at the four corners of the rectangular support surface 110, which can provide focused and precise protection for the corners of the support surface 110. Corners are usually places where objects are prone to collision and sliding during movement. This design can effectively prevent the transferred parts from accidentally detaching from the corners. For example, when the transfer device 1 suddenly accelerates or decelerates, the transferred parts are likely to rush towards the corners under the action of inertia. At this time, the baffles 320 groups can play a key blocking role. In addition, each group of baffles 320 consists of two baffles 320, which are respectively arranged near two adjacent sides of the rectangular support surface 110. This layout fully utilizes the corner space and achieves effective blocking without adding too much structure. Assuming that in a working environment with limited space, this compact design can ensure that it provides good protection while not occupying too much surrounding space. In addition, the four groups of baffles 320 at the corners work together to make the position of the transferred parts on the support surface 110 more stable. Even when the support surface 110 is tilted or subjected to uneven external forces, it can reduce the shaking and displacement of the transferred parts.

[0072] In one possible embodiment, see Figure 1 The transfer device 1 also includes a base plate 500, which is arranged below the carrier 100 in the vertical direction. An avoidance through hole 510 is provided on the base plate 500, and the avoidance through hole 510 is used to avoid the driving connecting rod 220 so that the driving connecting rod 220 can contact the carrier 100 through the avoidance through hole 510.

[0073] An embodiment of the present application further provides a battery production device, which includes the transfer device 1 in any one of the above embodiments.

[0074] Among them, the transfer device 1 in the embodiment of the present application can have the same structure as the transfer device 1 in the above embodiment, and can bring the same or similar beneficial effects.
