Description

Cover plate handling device and battery assembly equipment Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a cover plate handling device and battery assembly equipment. Background Technology

[0002] A battery consists of a casing, battery cells, and a cover. The casing has a cavity for accommodating the battery cells, and the cavity has an opening. The cover is used to seal the opening. During the battery production and assembly process, after the battery cells are placed in the cavity of the casing, the cover is used to seal the opening of the cavity.

[0003] In related technologies, cover plates are clamped and fixed from the material pile using existing cover plate handling devices and directly transferred to a subsequent fastening mechanism, which then fastens the cover plate to the outer shell. However, when clamping and fixing cover plates from the material pile using existing cover plate handling devices, it is difficult to ensure that the clamping position of different cover plates remains constant, resulting in low clamping accuracy. Since the handling path of existing cover plate handling devices is consistent, inconsistent clamping positions lead to inconsistent positions of the cover plates at the subsequent fastening mechanism, affecting the mechanism's ability to drive the cover plate to fasten and fix to the outer shell. Furthermore, existing cover plate handling devices can only clamp and fix one cover plate at a time, resulting in low handling efficiency and failing to meet practical requirements.

[0004] Therefore, there is an urgent need to invent a cover plate handling device and battery assembly equipment to solve the above problems. Summary of the Invention

[0049] The present invention 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 present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0050] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0052] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0053] This embodiment provides a battery assembly device, which includes a cell transport device, a housing transport device, a fastening device, and a cover plate transport device. The cell transport device can transport the cell to the fastening device, the housing transport device can transport the housing to the fastening device, the cover plate transport device can transport the cover plate to the fastening device, and the fastening device can place the cell into the housing and fasten and fix the housing and the cover plate.

[0054] In related technologies, existing cover plate handling devices struggle to ensure consistent clamping positions for different cover plates when clamping and securing them from a material pile. This results in low clamping accuracy. Furthermore, because the transport path of existing cover plate handling devices is uniform, inconsistent clamping positions lead to inconsistent positions of the cover plates at the fastening mechanism, affecting the subsequent fastening mechanism's drive to secure the cover plate to the outer casing. Additionally, existing cover plate handling devices can only clamp and secure one cover plate at a time, resulting in low handling efficiency and failing to meet practical requirements.

[0055] To address the aforementioned problems, as shown in Figure 1, this embodiment provides a battery cover transport device. The battery cover transport device includes a first transport mechanism 100, a secondary positioning mechanism 200, and a second transport mechanism 300. The first transport mechanism 100 can simultaneously clamp and fix multiple cover plates 2000 located at the material pile and simultaneously transfer the multiple cover plates 2000 to the secondary positioning mechanism 200. The secondary positioning mechanism 200 is configured to simultaneously position and fix multiple cover plates 2000. The second transport mechanism 300 can simultaneously clamp at least two cover plates 2000 located at the secondary positioning mechanism 200 and having completed positioning and fixing, and simultaneously drive at least two cover plates 2000 to move. The second transport mechanism 300 can adjust the distance between two adjacent cover plates 2000 along a preset direction so that each cover plate 2000 is transferred to a preset position.

[0056] This cover plate handling device uses a first handling mechanism 100 to simultaneously clamp and fix multiple cover plates 2000 from the material pile and simultaneously transfer the multiple cover plates 2000 to a secondary positioning mechanism 200. The secondary positioning mechanism 200 simultaneously positions and fixes the multiple cover plates 2000, realizing secondary positioning of the cover plates 2000. A second handling mechanism 300 clamps and fixes at least two of the fixed cover plates 2000 from the secondary positioning mechanism 200, ensuring the clamping and fixing accuracy of the cover plates 2000 by the second handling mechanism 300. Combined with the second handling mechanism 300 moving at least two cover plates 2000 while adjusting the distance between two adjacent cover plates 2000 along a preset direction, it achieves precise transfer of each cover plate 2000 relative to the preset position, ensuring the subsequent fastening effect of the cover plate 2000 to the outer shell, and greatly improving the handling efficiency of the cover plates 2000, meeting actual needs.

[0057] It should be noted that in this embodiment, the preset direction is left and right. In other embodiments, the specific direction of the preset direction can be adjusted according to actual needs, and this embodiment does not impose any specific limitations.

[0058] As an optional solution, as shown in Figures 1 and 2, the first conveying mechanism 100 includes multiple sets of first clamping components 130, a first vertical drive component 120, and a first horizontal drive component 110. The multiple sets of first clamping components 130 are spaced apart in the horizontal plane, and each set of first clamping components 130 can clamp and fix a cover plate 2000. The output end of the first vertical drive component 120 is connected to all the first clamping components 130 at the same time, and the first vertical drive component 120 can synchronously drive all the first clamping components 130 to move in the vertical direction. The output end of the first horizontal drive component 110 is connected to the first vertical drive component 120, and the first horizontal drive component 110 can drive the first vertical drive component 120 to move in the horizontal direction.

[0059] When it is necessary to move the cover plate 2000 at the material pile to the secondary positioning mechanism 200, the first horizontal drive component 110 and the first vertical drive component 120 cooperate to drive multiple sets of first clamping components 130 to move above the cover plate 2000. Then, the multiple sets of first clamping components 130 clamp and fix one cover plate 2000 respectively. After the cover plate 2000 is clamped and fixed, the first horizontal drive component 110 and the first vertical drive component 120 synchronously drive all the first clamping components 130 to move to the secondary positioning mechanism 200. Subsequently, the first clamping components 130 release the clamped and fixed cover plate 2000 to complete the transfer of the cover plate 2000 from the material pile to the secondary positioning mechanism 200. It should be noted that in this embodiment, the first conveying mechanism 100 has four sets of first clamping components 130, which are arranged at intervals in the left and right direction and are simultaneously connected to the output end of the first vertical drive component 120. In other embodiments, the specific number of the first clamping components 130 can be adjusted according to actual needs, and this embodiment does not impose a specific limitation.

[0060] Furthermore, in this embodiment, to further simplify the structure of the cover plate handling device, the first handling mechanism 100, the secondary positioning mechanism 200, and the second handling mechanism 300 are arranged sequentially in the left-right direction. The first horizontal drive assembly 110 only needs to drive the first vertical drive assembly 120 to move in the left-right direction. The first horizontal drive assembly 110 includes a stepper motor and a ball screw extending in the left-right direction. The first vertical drive assembly 120 includes a linear cylinder with a vertical driving direction; both are existing technologies and will not be described in detail here.

[0061] The specific structure of the first clamping assembly 130 is described with reference to Figure 2. Each first clamping assembly 130 includes two first grippers 131 arranged opposite to each other along a first direction and a first driving member 132. A clamping space is formed between the two first grippers 131. The first direction is parallel to the horizontal direction. The first driving member 132 is connected to the output end of the first vertical driving assembly 120. The output end of the first driving member 132 is also connected to both first grippers 131. The first driving member 132 can drive the two first grippers 131 to move towards each other or away from each other. By connecting the first driving member 132 to the output end of the first vertical driving assembly 120, and connecting the two first grippers 131 arranged opposite each other along the first direction to the output end of the first driving member 132 respectively, when the first vertical driving assembly 120 drives the first driving member 132 to move in the vertical direction, it can drive the two first grippers 131 to move in the vertical direction. When the first horizontal driving assembly 110 drives the first vertical driving assembly 120 to move in the left and right direction, it can drive the two first grippers 131 to move in the left and right direction. A driving component 132 drives two first grippers 131 to move towards each other or away from each other. When it is necessary to clamp and fix the cover plate 2000, the first driving component 132 drives the two first grippers 131 to move towards each other to reduce the size of the clamping space along the first direction, thereby clamping and fixing the cover plate 2000 located in the clamping space. When it is necessary to release the clamped and fixed cover plate 2000, the first driving component 132 drives the two first grippers 131 to move away from each other to increase the size of the clamping space along the first direction, thereby releasing the cover plate 2000 located in the clamping space. It should be noted that in this embodiment, the first direction is the left-right direction. In other embodiments, the specific direction of the first direction can also be adjusted according to actual needs. This embodiment does not impose a specific limitation.

[0062] Optionally, each first clamping assembly 130 further includes a first elastic abutment member 133. The two opposing end faces of the two first jaws 131 are respectively provided with a first part and a second part. The first part is located above the second part. Each first part within the two first jaws 131 is fixed with a first elastic abutment member 133. The second part can abut against the side wall of the cover plate 2000, and the lower end face of the first elastic abutment member 133 can elastically abut against the upper end face of the cover plate 2000. When the first vertical drive assembly 120 drives the first clamping assembly 130 downwards towards the cover plate 2000, the lower end faces of the two first elastic abutment members 133 within the first clamping assembly 130 can elastically abut against the upper end face of the cover plate 2000. This not only enables the first clamping assembly 130 to accurately clamp and fix the cover plate 2000, but also prevents the first clamping assembly 130 from crushing the cover plate 2000 during downward movement, thus improving the protection of the cover plate 2000. It should be noted that in this embodiment, the first elastic abutment 133 is a rubber block. Rubber has good elasticity, toughness, and wear resistance, and has a long service life. In other embodiments, the first elastic abutment 133 may also be made of sponge or other elastic materials; this embodiment does not impose specific limitations.

[0063] The specific structure of the secondary positioning mechanism 200 is described with reference to Figure 3. The secondary positioning mechanism 200 includes a platform 220, a second driving member 210, and an elastic abutment structure 230. The platform 220 has multiple positioning grooves 221 extending along a second direction. These grooves are spaced apart along a first direction, and each groove can accommodate and position a cover plate 2000. Each of the positioning grooves 221 has an avoidance notch 2211 at the same end along the second direction. The elastic abutment structure 230 is located near the positioning grooves 221 along the second direction. Near one end of the clearance notch 2211, the output end of the second driving member 210 is connected to the elastic abutment structure 230. The second driving member 210 can drive the elastic abutment structure 230 to move along the second direction. The output end of the elastic abutment structure 230 can simultaneously extend into all the positioning grooves 221 along the clearance notch 2211 or simultaneously move out of all the positioning grooves 221 along the clearance notch 2211. The output end of the elastic abutment structure 230 is configured to abut against the cover plate 2000. By providing multiple positioning grooves 221 extending along the second direction on the platform 220, the multiple positioning grooves 221 are arranged at intervals along the first direction, and clearance notches 2211 are provided at the same end of the multiple positioning grooves 221 in the second direction. When the cover plate 2000 is transferred into the positioning groove 221 by the first clamping assembly 130, the second driving member 210 drives the elastic abutment structure 230 to move along the second direction toward the clearance notch 2211 and presses the cover plate 2000 against the groove wall of the elastic abutment structure 230 and the positioning groove 221 along the second direction, thereby realizing the secondary positioning of the cover plate 2000.

[0064] It should be noted that in this embodiment, the first direction is the left-right direction and the second direction is the front-back direction. Since the first transport mechanism 100 is provided with four sets of first clamping components 130, in order to meet the transport requirements of the first transport mechanism 100, four positioning grooves 221 are provided on the platform 220 at intervals along the left-right direction. The distance between two adjacent positioning grooves 221 is equal to the distance between two connected sets of first clamping components 130 in the first transport mechanism 100, so that the cover plate 2000 clamped and fixed on the four sets of first clamping components 130 can be transferred to the platform 220 synchronously.

[0065] Furthermore, in this embodiment, the second drive component 210 is a linear cylinder, which has a simple structure, sensitive response, and is easy to assemble and disassemble. In other embodiments, the second drive component 210 may also be a linear motor or other linear drive structure; this embodiment does not impose specific limitations.

[0066] In one alternative embodiment, the elastic abutment structure 230 includes a first connecting member 231 and a plurality of elastic telescopic members 232. The first connecting member 231 is connected to the output end of the second driving member 210. The plurality of elastic telescopic members 232 are spaced apart on the first connecting member 231 in the left-right direction. Each elastic telescopic member 232 is directly opposite a positioning groove 221 in the front-back direction, and each elastic telescopic member 232 is capable of elastic deformation in the front-back direction. The elastic telescopic members 232 are configured to abut against the cover plate 2000. By spaced apart on the first connecting member 231 in the left-right direction, and ensuring that each elastic telescopic member 232 is directly opposite a positioning groove 221 in the front-back direction, when the elastic telescopic members 232 abut against the cover plate 2000 in the front-back direction, the elastic deformation of the elastic telescopic members 232 in the front-back direction enhances the protection of the cover plate 2000. It should be noted that in this embodiment, the elastic telescopic member 232 is a spring. In other embodiments, the elastic telescopic member 232 may also be a rubber block or other elastic structure.

[0067] In this embodiment, to ensure the accuracy of the spring's extension and retraction in the front-to-back direction, the first connecting member 231 is also provided with multiple guide posts extending in the front-to-back direction. Each end of the spring near the first connecting member 231 in the front-to-back direction is sleeved on a guide post. When the spring extends and retracts in the front-to-back direction, the guide posts can improve the deformation guidance of the spring.

[0068] In addition, the elastic abutment structure 230 also includes a protective cap 233. Each spring is covered with a protective cap 233 at one end near the positioning groove 221 in the front-back direction. The protective cap 233 can elastically abut against the cover plate 2000. By covering the end of the spring near the positioning groove 221 in the front-back direction with a protective cap 233, direct contact between the spring and the cover plate 2000 can be avoided, further improving the protection of the cover plate 2000.

[0069] In an optional embodiment, as shown in Figures 1 and 4, the second conveying mechanism 300 includes at least two sets of second clamping components 330, a spacing adjustment component 340, a second vertical drive component 320, and a second horizontal drive component 310 arranged at intervals in the left-right direction. Each set of second clamping components 330 can clamp and fix a cover plate 2000. The output end of the spacing adjustment component 340 is connected to all the second clamping components 330 simultaneously, and the spacing adjustment component 340 can drive each set of second clamping components 330 to move in the left-right direction independently. The output end of the second vertical drive component 320 is connected to the spacing adjustment component 340, and the second vertical drive component 320 can drive the spacing adjustment component 340 to move in the vertical direction. The output end of the second horizontal drive component 310 is connected to the second vertical drive component 320, and the second horizontal drive component 310 can drive the second vertical drive component 320 to move in the left-right direction. By connecting at least two sets of second clamping components 330 to the spacing adjustment component 340 respectively, and having each set of second clamping components 330 moved in the left and right direction by the spacing adjustment component 340, the distance between two adjacent cover plates 2000 can be adjusted in the left and right direction. Combined with the driving of the second vertical drive component 320 and the second horizontal drive component 310, each cover plate 2000 can be transferred from the secondary positioning mechanism 200 to a preset position.

[0070] It should be noted that the specific structure of the second horizontal drive component 310 is the same as that of the first horizontal drive component 110, the specific structure of the second vertical drive component 320 is the same as that of the first vertical drive component 120, and the specific structure of the second clamping component 330 is the same as that of the first clamping component 130. The specific structures of the second horizontal drive component 310, the second vertical drive component 320, and the second clamping component 330 will not be described in detail here.

[0071] In this embodiment, the second handling mechanism 300 includes two sets of second clamping components 330, and the spacing adjustment component 340 is a double-output cylinder. The two sets of second clamping components 330 are respectively connected to the two output shafts of the double-output cylinder.

[0072] Understandably, the cover plate 2000 has positive and negative terminals. When the first conveying mechanism 100 transfers the cover plate 2000 from the material pile to the secondary positioning mechanism 200, the cover plate 2000 can be placed into the positioning groove 221 with the positive and negative terminals arranged sequentially along the length direction, or it may be placed into the positioning groove 221 with the negative and positive terminals arranged sequentially along the length direction. In the subsequent fastening process between the cover plate 2000 and the outer shell, the cover plate 2000 can only be fastened and fixed to the outer shell with the positive and negative terminals arranged sequentially along the length direction. To prevent the cover plate 2000 from being fastened to the outer shell with the negative and positive electrodes arranged sequentially along the length direction, the second conveying mechanism 300 also includes a control component and at least two sets of calibration adsorption components 350. Each set of calibration adsorption components 350 is correspondingly set with a set of second clamping components 330. The second clamping components 330 can clamp and fix the cover plate 2000 in either a first state or a second state. In the first state, the positive electrode in the cover plate 2000 is located at the front end of the negative electrode along the front-back direction. In the second state, the positive electrode in the cover plate 2000 is located at the rear end of the negative electrode along the front-back direction. The calibration adsorption components 350 can adsorb and fix the cover plate 2000 clamped and fixed in the first state. The control component is communicatively connected to the calibration adsorption components 350 and the fastening device for fastening the cover plate 2000 and the outer shell. By equipping each set of second clamping components 330 with a set of verification adsorption components 350, the verification adsorption components 350 can only be adsorbed and fixed with the cover plate 2000 where the positive electrode is located at the front end of the negative electrode, so as to quickly distinguish the state of the cover plate 2000. Combined with the communication connection between the verification adsorption components 350 and the fastening device and the control component, the verification adsorption components 350 transmit the corresponding verification information to the fastening device. The fastening device determines whether the cover plate 2000 needs to be flipped again according to the verification information, which can ensure that the cover plate 2000 is fastened and fixed with the outer shell in the correct state, and ensure the fastening effect of the cover plate 2000 and the outer shell in the future.

[0073] It should be noted that in this embodiment, the calibration adsorption component 350 is a negative pressure suction cup. Since the cover plate 2000 is equipped with an explosion-proof valve, when the cover plate 2000 is clamped and fixed by the second clamping component 330 in the first state, the explosion-proof valve and the negative pressure suction cup are misaligned, allowing the negative pressure suction cup to adsorb and fix the cover plate 2000. When the cover plate 2000 is clamped and fixed by the second clamping component 330 in the second state, the explosion-proof valve and the negative pressure suction cup are directly opposite each other, and the negative pressure suction cup cannot adsorb and fix the cover plate 2000.
