[0032] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. It should also be understood that the terminology used in the embodiments of this utility model is for describing specific implementation schemes and not for limiting the scope of protection of this utility model. Test methods in the following embodiments that do not specify specific conditions are generally performed under conventional conditions or according to the conditions recommended by the respective manufacturers.

[0033] When numerical ranges are given in the embodiments, it should be understood that, unless otherwise specified in this invention, both endpoints of each numerical range and any value between the two endpoints may be selected. Unless otherwise defined, all technical and scientific terms used in this invention, as well as the prior art known to those skilled in the art and the description of this invention, may be implemented using any prior art methods, equipment, and materials similar to or equivalent to those in the embodiments of this invention.

[0034] It should be noted that the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0035] The production of battery cells involves numerous steps and multiple transfers. After the final inspection of the battery pack film, robotic arms are required to sort and palletize them. The cells are covered with a fragile blue film that is easily scratched. Poor positioning accuracy can cause the blue film to be bumped and scratched during the robotic arm's palletizing process, necessitating manual removal of the cells from the pallet and re-tearing of the film for rework. This is a late stage in battery cell production, and rework requires the cells to undergo multiple processes again, significantly reducing production line efficiency.

[0036] Please see Figures 1 to 9In view of this, this application provides a battery cell receiving device, including a receiving mechanism 100, multiple lifting mechanisms 200, and a traversing mechanism 300. The receiving mechanism 100 includes a receiving section 110 and multiple support sections 120. Each support section 120 forms a receiving area for accommodating the battery cell 400. The receiving area positions the battery cell 400 in a regular manner, improving the positioning accuracy of the battery cell 400 and facilitating gripping by a robotic arm. By setting multiple support sections 120 to form multiple receiving areas, multiple battery cells 400 can be gripped by a robotic arm simultaneously, effectively improving the efficiency of the robotic arm in gripping the tray and increasing production line efficiency. The receiving section 110 moves the battery cell 400 to the receiving area. By feeding multiple receiving areas through one receiving section 110, the number of receiving sections 110 is reduced, thereby reducing the number of drive mechanisms and lowering the cost of the receiving device. The lifting mechanism 200 includes a first driving mechanism 210 and a lifting part 220. Multiple sets of the lifting mechanisms 200 correspond to multiple sets of the support parts 120. The first driving mechanism 210 drives the lifting part 220 to move, so that the lifting part 220 lifts the battery cell 400 away from the receiving part 110. After the battery cell 400 reaches the preset position of the receiving part 110, the lifting part 220 lifts the battery cell 400 away from the receiving part 110. The receiving part 110 continues to feed materials to other receiving areas, avoiding the receiving part 110 from continuously acting on the battery cell 400 that has reached the receiving area, thus protecting the battery cell 400, reducing wear on the battery cell 400, reducing the probability of damage to the blue film on the surface of the battery cell 400, and improving the yield rate. The transverse mechanism 300 includes a second drive mechanism 310 and a movable base plate 320. The receiving mechanism 100 and the lifting mechanism 200 are disposed on the movable base plate 320. The second drive mechanism 310 drives the movable base plate 320 to move so that multiple receiving areas sequentially connect to the discharge port of the battery cell 400. After the battery cell 400 is transported to the receiving area, the transverse mechanism 300 drives the receiving mechanism 100 to move so that multiple receiving areas can sequentially connect to the discharge port of the battery cell 400, completing the sequential receiving of multiple receiving areas, thereby facilitating the robot arm to grasp and assemble the tray, and improving efficiency.

[0037] Please see Figure 1 In one embodiment, two side plates 330 are fixed to the movable base plate 320. The fixing methods between the two side plates 330 and the movable base plate 320 include, but are not limited to, welding connection, bolt connection, etc. The two side plates 330 and the movable base plate 320 can also be fixed in a relatively fixed manner, such as integral molding. The two side plates 330 and the movable base plate 320 together provide installation space for the lifting mechanism 200 and the receiving mechanism 100, so as to facilitate the installation of the lifting mechanism 200 and the receiving mechanism 100.

[0038] The two side plates 330 are located at both ends of the moving base plate 320 in the moving direction, so as to form open openings on the other two sides of the moving base plate 320 to facilitate the receiving of the battery cell 400 and avoid interference.

[0039] Please see Figure 1 In one embodiment, each set of support portions 120 includes a first side support portion 121, a second side support portion 122, and a rear support portion 123. The first side support portion 121, the second side support portion 122, and the rear support portion 123 form a receiving area with an opening. The battery cell 400 enters the receiving area through the opening. The first side support portion 121 and the second side support portion 122 perform regular positioning of the battery cell 400, and the rear support portion 123 limits the movement of the battery cell 400, working together to ensure the transport accuracy of the battery cell 400.

[0040] Please see Figure 7 The first side support portion 121 is provided with a plurality of first rollers 124, and the first rollers 124 protrude from the first side support portion 121 toward the receiving area. The axis of the first rollers 124 is perpendicular to the movement direction of the battery cell 400. After the battery cell 400 moves to the receiving area and comes into contact with the first rollers 124, the first rollers 124 roll along the surface of the battery cell 400, avoiding relative sliding between the battery cell 400 and the surface of the first side support portion 121, reducing the movement resistance of the battery cell 400 in the receiving area, reducing the probability of damage to the blue film on the surface of the battery cell 400, and improving the yield of the battery cell 400.

[0041] To further reduce the probability of surface damage to the battery cell 400, the contact surface between the first roller 124 and the battery cell 400 is covered with a flexible layer. The flexible layer can be made of materials such as rubber, silicone, or flexible plastic to avoid rigid contact between the battery cell 400 and the first roller 124, protect the blue film on the surface of the battery cell 400, reduce wear and bumps, and improve the yield of the battery cell 400.

[0042] Please see Figure 8 The second side support 122 has a plurality of first rollers 124 on the side facing the first side support 121, and the first rollers 124 protrude from the second side support 122 toward the receiving area. The axial direction of the first rollers 124 on the second side support 122 is perpendicular to the movement direction of the battery cell 400, so that when the first rollers 124 move relative to the battery cell 400, the first rollers 124 roll along the surface of the battery cell 400. The battery cell 400 contacts the first rollers 124 on the second side support 122, avoiding relative sliding between the battery cell 400 and the surface of the second side support 122, reducing the movement resistance of the battery cell 400 in the receiving area, and reducing the probability of damage to the blue film on the surface of the battery cell 400.

[0043] Please see Figure 6In one embodiment, two rows of first rollers 124 are provided on opposite sides of the first side support 121 and the second side support 122. The two rows of first rollers 124 on the first side support 121 are arranged vertically, and the two rows of first rollers 124 on the second side support 122 are arranged vertically. The two rows of first rollers 124 provide support for the side of the battery cell 400, reducing the probability of the battery cell 400 tilting, ensuring that the battery cell 400 moves along a preset trajectory, and improving the positioning accuracy of the battery cell 400.

[0044] Of course, as some alternatives, the opposite sides of the first side support 121 and the second side support 122 may be provided with three, four or more rows of first rollers 124 to facilitate support of the battery cell 400.

[0045] Please see Figure 1 and Figure 3 The rear support portion 123 is disposed at the end of the first side support portion 121 and the second side support portion 122. The rear support portion 123 is disposed at one end of the first side support portion 121 and the second side support portion 122, and the other end of the first side support portion 121 and the second side support portion 122 forms an opening. The battery cell 400 moves from the opening into the receiving area until the battery cell 400 abuts against the rear support portion 123. The rear support portion 123 restricts the further movement of the battery cell 400 so that the battery cell 400 is kept in the receiving area.

[0046] In one embodiment, the two ends of the rear support 123 are respectively fixed to the two side plates 330 to facilitate the installation of the rear support 123.

[0047] Furthermore, a flexible layer is provided on the contact surface between the rear support 123 and the battery cell 400. The flexible layer can be made of materials such as rubber, silicone, or flexible plastic to achieve soft contact between the rear support 123 and the battery cell 400, reduce rigid contact between the battery cell 400 and the rear support 123 when the battery cell 400 moves to the rear support 123, reduce the impact and collision on the battery cell 400, reduce the damage to the battery cell 400, and improve the yield of the battery cell 400.

[0048] In one embodiment, the rear support portions 123 of the multiple sets of support portions 120 are relatively fixed. The fixing method can be integral molding, welding connection, bolt connection, etc. Preferably, the rear support portions 123 of the multiple sets of support portions 120 are integrally molded. In other words, the multiple sets of support portions 120 share a single rear support portion 123 to facilitate the assembly and installation of the battery cell receiving device. If multiple rear support portions 123 are installed separately, errors in the limiting position of the battery cell 400 in the receiving area may occur due to installation errors. By using a single rear support portion 123, errors between receiving areas caused by the installation of the rear support portions 123 can be avoided, thereby improving the limiting accuracy of the battery cell 400.

[0049] Please see Figure 1 and Figure 4 In one embodiment, the receiving part 110 includes a plurality of rollers 111 and a third drive mechanism. The plurality of rollers 111 are arranged side by side, and the third drive mechanism drives the rollers 111 to rotate, thereby moving the battery cells 400 on the rollers 111. By transporting the battery cells 400 by the side-by-side rollers 111, the possibility of damage to the surface of the battery cells 400 from impacts can be reduced.

[0050] To reduce the impact on the battery cell 400, the contact area between the roller 111 and the battery cell 400 is covered with a flexible layer. The flexible layer can be made of materials such as rubber, silicone or flexible plastic to achieve soft contact between the roller 111 and the battery cell 400, further reducing the impact between the battery cell 400 and the roller 111.

[0051] In one embodiment, the two ends of the roller 111 are rotatably mounted on two side plates 330 to facilitate the installation of the roller 111.

[0052] The third drive mechanism can be a motor or other drive mechanism. Preferably, the third drive mechanism includes a motor and a synchronous belt. The motor directly drives one roller 111 as the active roller 111. Multiple rollers 111 are connected by a synchronous belt so that the active roller 111 drives the other driven rollers 111 to rotate, thereby realizing the receiving and transportation of the battery cell 400.

[0053] In one embodiment, a mounting area is provided on the top of one side plate 330, where the motor and timing belt are installed to avoid exposing the motor and timing belt, thereby improving safety and reducing the risk of accidental injury to workers.

[0054] Please see Figures 6 to 8 To facilitate the robotic arm's gripping of the battery cell 400, the upper part of the battery cell 400 typically extends beyond the support portion 120. This is because the first side support portion 121 and the second side support portion 122 usually need to extend downwards through the receiving portion 110. The first side support portion 121 includes a transverse connecting rod and multiple longitudinal connecting rods. The transverse connecting rod can be positioned above or below the roller 111. Multiple transverse connecting rods can also be included, respectively positioned above and below the roller 111, to improve the strength of the first side support portion 121 and the second side support portion 122, ensuring support for the battery cell 400. Preferably, multiple transverse connecting rods are included, respectively positioned above and below the roller 111, and the first roller 124 is mounted on the transverse connecting rod located above the roller 111.

[0055] Multiple longitudinal connecting rods are included, and these multiple longitudinal connecting rods are fixed to the transverse connecting rods so that the first side support 121 forms a whole. The longitudinal connecting rods pass through the roller 111 so that the portion of the first side support 121 above the roller 111 forms a receiving area to support the battery cell 400; the portion of the first side support 121 below the roller 111 is connected to other structures for installation of the first side support 121.

[0056] Please see Figure 8 Similarly, the second side support 122 also includes a transverse connecting rod and multiple longitudinal connecting rods. The arrangement of the transverse connecting rods and longitudinal connecting rods of the second side support 122 can be the same as that of the first side support 121, so as to provide a more balanced support for the battery cell 400 on both sides.

[0057] Of course, as some alternatives, the configuration of the transverse connecting rod and the longitudinal connecting rod of the second side support 122 can be different from that of the transverse connecting rod and the longitudinal connecting rod of the first side support 121, as long as it can provide stable support for the battery cell 400.

[0058] Please see Figure 4 In one embodiment, the receiving mechanism 100 includes a connecting plate 130, a fourth guide rail 140, a fourth slider 131, and a fourth driving mechanism 150.

[0059] Several second-side support portions 122 are fixed to the connecting plate 130, so that the multiple second-side support portions 122 form a whole, which is driven by the fourth drive mechanism 150 to move along the fourth guide rail 140. The fixing methods of the second-side support portions 122 and the connecting plate 130 include, but are not limited to, bolt connection, welding connection, plug connection, and integral molding connection.

[0060] In one embodiment, the connecting plate 130 is provided with a connecting portion and a plurality of connecting holes arranged along the length direction of the fourth guide rail 140. The second side support portion 122 is detachably fixed to the connecting holes via connectors. By connecting the second side support portion 122 to different connecting holes, the relative position of the second side support portion 122 and the connecting plate 130 can be changed. When the specifications of the battery cell 400 change, it is convenient to adjust the feeding mechanism 100 to meet the feeding requirements of battery cells 400 of different specifications.

[0061] The fourth guide rail 140 is fixed relative to the movable base plate 320, the fourth slider 131 is matched with the fourth guide rail 140, and the fourth slider 131 is fixed with the connecting plate 130, so that the connecting plate 130 can move along the fourth guide rail 140.

[0062] In one embodiment, the two ends of the fourth guide rail 140 are fixed to the two side plates 330 respectively, so that the fourth guide rail 140 is relatively fixed to the movable base plate 320.

[0063] In one embodiment, the fourth slider 131 and the connecting part are the same component. By providing multiple connecting holes on the fourth slider 131, the second side support 122 is fixed to the fourth slider 131, so that the second side support 122 is fixed to the connecting plate 130. One component performs multiple functions, which improves the utilization rate of the component.

[0064] Of course, as some alternatives, the fourth slider 131 and the connecting part can also be different components.

[0065] The fourth drive mechanism 150 drives the connecting plate 130 to move along the fourth guide rail 140, the length direction of which is the same as the movement direction of the moving base plate 320. After the receiving area completes receiving, the fourth drive mechanism 150 drives the connecting plate 130 to move, which in turn drives the second side support 122 to move closer to the first side support 121, pushing and pressing the battery cell 400 towards the first side support 121 to further position the battery cell 400. This effectively improves the positioning accuracy of the battery cell 400, making it easier for the robot to grasp. It also effectively reduces the occurrence of bumps and damage to the blue film caused by the robot grasping the tray due to the low positioning accuracy of the battery cell 400, thereby improving the yield and production efficiency.

[0066] Please see Figure 9 In one embodiment, the fourth drive mechanism 150 includes a telescopic cylinder 151, which is fixed relative to the fourth guide rail 140. The push rod of the telescopic cylinder 151 is directly or indirectly connected to the connecting plate 130, so that the telescopic cylinder 151 pushes the connecting plate 130 to move along the fourth guide rail 140. The telescopic cylinder 151 can be a hydraulic telescopic cylinder 151, a pneumatic telescopic cylinder 151, or an electric telescopic cylinder 151, etc.

[0067] In other embodiments, the fourth drive mechanism 150 may also be a combination of a motor and a lead screw to drive the connecting plate 130 to move relative to the fourth guide rail 140.

[0068] Please see Figure 9In one embodiment, the fourth drive mechanism 150 includes a telescopic cylinder 151, a buffer 152, and a guide rod. The buffer 152 is disposed between the push rod of the telescopic cylinder 151 and the connecting plate 130; the guide rod is connected to the push rod of the telescopic cylinder 151 and slidably connected to the connecting plate 130, and the length direction of the guide rod is consistent with the length direction of the fourth guide rail 140. Compared with the telescopic cylinder 151 directly pushing the connecting plate 130 to move, the telescopic cylinder 151 indirectly pushes the connecting plate 130 to move by pushing the buffer 152, making the movement of the connecting plate 130 more uniform. The buffer 152 can provide cushioning, reducing the impact of the second side support 122 on the battery cell 400, thereby reducing the probability of damage to the battery cell 400 caused by the second side support 122 pushing the battery cell 400, and improving the yield of the battery cell 400.

[0069] The buffer 152 can be an elastic component such as a rubber pad or a spring. Preferably, the buffer 152 is a spring, which is sleeved outside the guide rod. The guide rod limits the spring, reducing radial bending or movement when the spring is compressed. This allows the telescopic cylinder 151 to stably push the spring to move, thereby driving the second-side support 122. When the battery cell 400 is being aligned, the telescopic cylinder 151 compresses the spring. When the spring force is sufficient to drive the connecting plate 130 to move, or when the spring is compressed to its limit, the spring presses against the connecting plate 130, causing the connecting plate 130 to move. The initial movement of the connecting plate 130 is relatively slow, thereby effectively reducing the impact of the second-side support plate on the battery cell 400, reducing the impact damage to the battery cell 400, and improving the yield rate.

[0070] In one embodiment, two fourth drive mechanisms 150 are provided, and the two fourth drive mechanisms 150 are symmetrically arranged on both sides of the second side support 122, so as to simultaneously drive the second side support 122 to move towards the first side support 121 from both sides of the second side support 122, thereby improving the stability of the movement of the second side support 122, preventing the second side support 122 from tilting, and making the force on the large surface of the battery cell 400 uniform.

[0071] Please see Figure 7In one embodiment, the lifting portion 220 is fixed to the first side support portion 121, and the lifting portion 220 is located between the rollers 111, such that the contact point between the lifting portion 220 and the battery cell 400 protrudes and retracts into the roller 111 along the movement direction of the lifting portion 220. When the receiving portion 110 transports the battery cell 400 to the receiving area, the lifting portion 220 retracts into the roller 111, that is, the height of the contact surface between the lifting portion 220 and the battery cell 400 is lower than the top height of the roller 111; when the battery cell 400 is transported to a preset position in the receiving area, the lifting portion 220 moves upward to push the battery cell 400 located in the receiving area away from the receiving portion 110, so as to avoid the receiving portion 110 continuously acting on the battery cell 400. To facilitate the robotic arm's gripping of the battery cells 400, the lifting part 220 and the first side support part 121 are both fixed below the roller 111 to avoid interference between the robotic arm and the lifting part 220 and the first side support part 121. Fixing the lifting part 220 to the first side support part 121 facilitates their installation. Preferably, the lifting part 220 and the first side support part 121 are integrally formed to reduce the number of parts and improve the assembly speed of the receiving device.

[0072] In one embodiment, the lifting part 220 is fixed on the longitudinal connecting rod to facilitate the lifting part 220 to move up and down in the gap of the roller 111.

[0073] In one embodiment, a flexible layer is provided at the contact point between the lifting part 220 and the battery cell 400. The flexible layer can be made of materials such as rubber, silicone, or flexible plastic to avoid rigid contact between the lifting part 220 and the battery cell 400, reduce the probability of the battery cell 400 being bumped or damaged, and improve the yield rate.

[0074] Please see Figure 7 In one embodiment, the first side support 121 is connected to the first drive mechanism 210. This connection allows the first drive mechanism 210 to connect with the lifting part 220, enabling the first drive mechanism 210 to move the lifting part 220 up and down. The lower side of the first side support 121 typically includes a transverse connecting rod, resulting in a relatively large height of the first side support 121 below the roller 111. Connecting the first drive mechanism 210 to the first side support 121, thereby driving the lifting part 220, effectively reduces the height of the first side support 121, saving materials, reducing costs, and decreasing the weight required to drive the first drive mechanism 210, thus facilitating the selection of the first drive mechanism 210.

[0075] Please see Figure 4In one embodiment, a first mounting part 321 is provided on the movable base plate 320, and the first driving mechanism 210 is mounted on the first mounting part 321. The position of the first mounting part 321 on the movable base plate 320 is adjustable. By adjusting the position of the first mounting part 321 on the movable base plate 320, the position of the first side support part 121 can be adjusted, thereby improving the installation accuracy of the first side support part 121.

[0076] Please see Figure 4 In one embodiment, a second mounting portion 323 is fixed on the movable base plate 320. The second mounting portion 323 has several elongated holes. The first mounting portion 321 is fixed to the elongated holes via connectors. For example, the first mounting portion 321 is fixed in the elongated holes by bolts. By adjusting the position of the bolts in the elongated holes, the position of the first mounting portion 321 can be adjusted, thereby fine-tuning the position of the first side support portion 121 to improve its positional accuracy. Consequently, after the second side support portion 122 pushes the battery cell 400 towards the first side support portion 121, the positioning of the battery cell 400 is more accurate, facilitating the robotic arm's gripping of the assembled battery cell 400 and reducing the risk of damage from impacts.

[0077] In one embodiment, two second mounting portions 323 are symmetrically arranged on the movable base plate 320. The two ends of the first mounting portion 321 are respectively fixed to the two second mounting portions 323 to improve the stability of the first drive mechanism 210 installation.

[0078] Please see Figure 4 In one embodiment, a first guide rail 322 is provided on the movable base plate 320, and a first slider 3211 is provided at the bottom of the first mounting part 321. The first slider 3211 matches the first guide rail 322. By cooperating with the first guide rail 322, the first mounting part 321 is conveniently installed, ensuring that the first mounting part 321 is consistent in the horizontal direction, thereby improving the consistency of the installation position of the multiple first side support parts 121, and thus making the battery cells 400 in the multiple receiving areas accurately positioned.

[0079] In one embodiment, the first drive mechanism 210 is a telescopic rod. The lifting movement of the jacking part 220 is simple, requiring only two hovering positions. The telescopic rod has a simple structure, low cost, and stable operation, ensuring the lifting movement of the jacking part 220 while reducing costs. The telescopic rod can be a hydraulic telescopic rod, a pneumatic telescopic rod, an electric telescopic rod, etc.

[0080] Of course, as some alternatives, the first drive mechanism 210 can also be a combination of a motor and a ball screw, or other structures that can drive the lifting part 220 to rise and fall.

[0081] In one embodiment, the lifting mechanism 200 includes a limiting device 230, which restricts the lifting part 220 from moving in a preset direction. The limiting device 230 improves the stability of the lifting part 220 during lifting and lowering, and avoids tilting or misalignment of the lifting part 220 during lifting and lowering.

[0082] Please see Figure 9 In one embodiment, a mounting plate 340 is provided between the two side plates 330, and the two ends of the mounting plate 340 are respectively fixed to the two side plates 330.

[0083] Please see Figure 4 and Figure 7 The limiting device 230 includes a limiting rod 232 and a plurality of second rollers 231. The limiting rod 232 is fixed relative to the lifting part 220. The second rollers 231 are mounted on the mounting plate 340 and are symmetrically arranged on both sides of the limiting rod 232. The second rollers 231 press against the limiting rod 232, so that the limiting rod 232 moves between the second rollers 231, thereby preventing the limiting rod 232 from tilting when moving up and down, reducing the shaking of the limiting rod 232, improving the stability of the operation of the limiting rod 232, and ensuring that the lifting part 220 can smoothly lift the battery cell 400.

[0084] In one embodiment, the limiting rod 232 is fixed to the first side support plate so that the limiting rod 232 is relatively fixed to the lifting part 220.

[0085] In one embodiment, the fourth guide rail 140 is mounted on the mounting plate 340 to effectively utilize the mounting plate 340, facilitate the assembly of the receiving device, and improve the compactness of the receiving device.

[0086] Please see Figure 1 and Figure 4 In one embodiment, the lateral movement mechanism 300 includes a mounting base 350, a second guide rail 360, and a second slider 370. The second guide rail 360 is disposed on the mounting base 350, and the second slider 370 is disposed on the movable base plate 320. The second slider 370 cooperates with the second guide rail 360 to allow the movable base plate 320 to move along the second guide rail 360. The cooperation between the second slider 370 and the second guide rail 360 guides the movable base plate 320, ensuring that the movable base plate 320 moves in a predetermined direction.

[0087] In one embodiment, the second drive mechanism 310 includes a motor and a ball screw. A slider is provided at the bottom of the movable base plate 320. The motor drives the ball screw to rotate, thereby causing the slider to move horizontally, and in turn, causing the movable base plate 320 to move.

[0088] Of course, as some alternatives, the second drive mechanism 310 can also be a motor and gear rack, linear motor, or magnetic levitation transmission mechanism, etc., to drive the movable base plate 320 to move along the second guide rail 360.

[0089] When the battery cell receiving device of this application is in operation, the transverse mechanism 300 drives the receiving mechanism 100 to move, so that the receiving area corresponds to the discharge port of the battery cell 400. The receiving part 110 transports the battery cell 400 to the receiving area, and the longitudinal positioning of the battery cell 400 is completed by the rear support part 123. The battery cell 400 is lifted by the lifting mechanism 200 and removed from the receiving part 110. The transverse mechanism 300 switches to another receiving area to correspond to the discharge port of the battery cell 400, and repeats the receiving action until the receiving area is full of battery cells 400. All battery cells 400 are lifted by the lifting mechanism 200 and transported by the second side support part 123. 2. The first side support 121 moves, pushing the battery cell 400 to move. The positioning of the battery cell 400 is completed through the cooperation of the first side support 121 and the second side support 122. The transverse mechanism 300 drives the receiving mechanism 100 to move, so that the battery cell 400 moves to the material picking position of the robot arm. The robot arm clamps the battery cell 400, and the second side support 122 moves away from the first side support 121. That is, the second side support 122 and the first side support 121 no longer squeeze the battery cell 400. The robot arm picks up the material and puts it on the tray. The battery cell receiving device completes the receiving and feeding action.

[0090] This utility model's battery cell receiving device feeds multiple receiving areas through a single receiving section 110, reducing the number of receiving sections 110 required. A lifting mechanism 200 lifts the battery cell 400 away from the receiving section 110, preventing continuous action from the receiving section 110 and reducing wear on the battery cell 400. A rear support section 123 limits the positioning of the battery cell 400, and a second side support section 122 moves towards the first side support section 121 to further position the battery cell 400, improving its positioning accuracy. This facilitates robotic arm gripping and assembly, reduces impacts and scratches on the surface blue film of the battery cell 400, reduces manual rework inspection, improves production efficiency, and increases yield. Therefore, this utility model effectively overcomes some practical problems in the prior art, thus having high utilization value and practical significance.

[0091] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
