For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication 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 according to the specific circumstances.

[0033] The battery pressure-holding and shaping device 10 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0034] like Figure 1 and Figure 2 As shown, the battery pressure holding and shaping device 10 according to an embodiment of the present utility model includes a pressing and positioning device 1 and a pressure holding and shaping device 2.

[0035] Specifically, see the attached document. Figure 1 and attached Figure 2 As shown, the clamp 20 can fix the battery 101, ensuring reliable fixation of the battery 101 and facilitating subsequent processing of the battery 101. The clamping and positioning device 1 is used to position the clamp 20 that fixes the battery 101 and drive the clamp 20 to clamp the battery 101. It can fix the relative position of the clamp 20 at the battery pressure shaping equipment 10, so that the position of the battery 101 is consistent, which facilitates the processing of the battery 101 by the battery pressure shaping equipment 10.

[0036] Further, see attached document. Figure 4 and attached Figure 5 As shown, the pressure-holding and shaping device 2 and the clamping and positioning device 1 are aligned along the first horizontal direction (e.g., Figure 4 As shown, the clamp 20 is arranged between the pressing and positioning device 1 and the pressure holding and shaping device 2. The pressure holding and shaping device 2 is used to hold pressure on the side sealing edge 102 of the battery 101 and to shape the top sealing edge 103 of the battery 101.

[0037] It is understandable that by applying pressure to the side sealing edge 102 of the battery 101 using the pressure-holding and shaping device 2, the springback rate of the aluminum-plastic film can be reduced (e.g., springback rate ≤ 0.5%), preventing warping of the side sealing edge 102 and electrolyte leakage, thereby improving the sealing performance and safety of the battery 101, ensuring the quality of the battery 101, and extending the service life of the battery 101. By shaping the top sealing edge 103 of the battery 101 using the pressure-holding and shaping device 2, encapsulation defects can be eliminated, the sealing performance of the battery 101 can be improved, electrolyte leakage or external moisture / oxygen intrusion can be prevented, and the electrical connection reliability of the battery 101 can be improved. Furthermore, since irregular top sealing edge 103 may cause uneven stress on the tab 104 (such as local compression or tension), leading to fatigue fracture, shaping the top sealing edge 103 of the battery 101 can even out the stress distribution, enhance the connection strength between the tab 104 and the cell electrode, and extend the electrical connection life.

[0038] The pressure holding and shaping device 2 has the functions of both holding pressure on the side sealing edge 102 of the battery 101 and shaping the top sealing edge 103 of the battery 101. It can realize that one device can simultaneously hold pressure on the side sealing edge 102 and shape the top sealing edge 103 of the battery 101, thereby relatively reducing the production process of the battery 101, improving the production efficiency of the battery 101, and matching the high-speed production cycle.

[0039] It should be noted that by positioning the clamp 20 between the clamping and positioning device 1 and the pressure-holding and shaping device 2, the clamp 20 can be positioned from one side along the first direction, and then the battery 101 on the clamp 20 can be pressure-held and shaped from the other side along the first direction. This can avoid interference between the clamping and positioning device 1 and the pressure-holding and shaping device 2 during operation, and ensure the positioning effect of the clamping and positioning device 1 on the clamp 20 and the pressure-holding and shaping effect of the pressure-holding and shaping device 2 on the battery 101.

[0040] According to the embodiment of the present invention, the battery pressure holding and shaping equipment 10 includes a clamping and positioning device 1 and a pressure holding and shaping device 2. The clamping and positioning device 1 is used to position the clamp 20 that fixes the battery 101 and drive the clamp 20 to clamp the battery 101. The pressure holding and shaping device 2 is used to hold pressure on the side sealing edge 102 of the battery 101 and to shape the top sealing edge 103 of the battery 101. On the one hand, it can reduce the rebound rate of the aluminum-plastic film, avoid electrolyte leakage, improve the sealing and safety of the battery 101, ensure the quality of the battery 101, and extend the service life of the battery 101. On the other hand, it can uniformly distribute stress, enhance the connection strength between the tab 104 and the cell electrode, extend the electrical connection life, and enable one device to simultaneously hold pressure on the side sealing edge 102 and shape the top sealing edge 103 of the battery 101. This can relatively reduce the production steps of the battery 101, improve the production efficiency of the battery 101, and match the high-speed production cycle.

[0041] In some embodiments of this utility model, reference is made to the appendix. Figure 2 and attached Figure 3 As shown, the pressure-holding and shaping device 2 includes a first base 21, a pressure-holding module 22, and a shaping module 23. The pressure-holding module 22 and the shaping module 23 are disposed on the first base 21 and along a horizontal second direction (e.g., Figure 2 As shown, the battery 101 is arranged in a first direction and a second direction perpendicular to each other. The pressure holding module 22 and the shaping module 23 are movable along the first direction. The pressure holding module 22 is used to hold the pressure on the side sealing edge 102 of the battery 101, and the shaping module 23 is used to shape the top sealing edge 103 of the battery 101.

[0042] It should be noted that when the battery 101 is placed on the clamp 20, the axial direction of the battery 101 is as follows: Figure 3 The second direction shown allows the pressure-holding module 22 and the shaping module 23 to be arranged in the second direction, so that the pressure-holding module 22 is opposite to the side sealing edge 102 of the battery 101 and the shaping module 23 is opposite to the top sealing edge 103 of the battery 101, thus avoiding interference between the pressure-holding module 22 and the shaping module 23 during operation.

[0043] It is understandable that the pressure holding module 22 and the shaping module 23 are movable along the first direction. When the clamp 20 moves to the battery pressure holding and shaping device 10, after the clamping and positioning device 1 positions the clamp 20 that fixes the battery 101 and drives the clamp 20 to clamp the battery 101, the pressure holding module 22 and the shaping module 23 can move along the first direction toward the direction closer to the clamping and positioning device 1 to achieve pressure holding on the side sealing edge 102 of the battery 101 and shaping on the top sealing edge 103 of the battery 101. After the pressure holding and shaping are completed, the pressure holding module 22 and the shaping module 23 can move along the first direction toward the direction away from the clamping and positioning device 1, so that the clamp 20 leaves the battery pressure holding and shaping device 10 and avoids affecting the movement of the clamp 20.

[0044] It should be noted that the reference appendix Figure 3 As shown, there are two shaping modules 23, located at opposite ends of the pressure-holding module 22 along the second direction, thus matching the shape of the battery 101. This allows the pressure-holding module 22 to maintain pressure on the side sealing edges 102 of the battery 101. The two shaping modules 23 also adjust the axial direction of the battery 101 (e.g., ...). Figure 3 The two top sealing edges 103 at both ends of the second direction shown are shaped to further improve the processing efficiency of the battery pressure holding and shaping equipment 10 for the battery 101.

[0045] In a further embodiment of this utility model, reference is made to the appendix. Figure 6 As shown, the end of the pressure-holding module 22 facing the clamping and positioning device 1 has a pressure-holding arc surface 221. The pressure-holding arc surface 221 is suitable for driving the side sealing edge 102 of the battery 101 to fit against the outer peripheral wall of the battery 101. On the cross section perpendicular to the second direction, the pressure-holding arc surface 221 is formed into an arc shape, realizing the contour processing of the pressure-holding arc surface 221, so that the pressure-holding arc surface 221 can fit against the outer peripheral wall of the battery 101, thereby enabling the side sealing edge 102 of the battery 101 to fit against the outer peripheral wall of the battery 101 well, and improving the pressure-holding effect of the pressure-holding module 22.

[0046] In a further embodiment of this utility model, a buffer is provided on the pressure-holding arc surface 221, which can prevent the pressure-holding module 22 from directly contacting the side sealing edge 102 of the battery 101, avoid excessive impact force from the pressure-holding module 22 that could damage the side sealing edge 102 of the battery 101, reduce the breakage rate of the aluminum-plastic film, and thus reduce the production and processing cost of the battery 101. For example, the buffer can be a 1mm thick silicone sheet.

[0047] In a further embodiment of this utility model, the pressure holding module 22 is a brass component. Brass has a high thermal conductivity, which can quickly transfer heat during the pressure holding process, ensuring that the surface temperature of the pressure holding module 22 is uniform, avoiding local overheating that could lead to uneven melting or degradation of the aluminum-plastic film, ensuring the tightness of the sealing interface, and ensuring the uniformity of the pressure applied by the pressure holding module 22 to the side sealing edge 102 of the battery 101.

[0048] In a further embodiment of this utility model, reference is made to the appendix. Figure 3 As shown, the shaping module 23 has a shaping groove 230 extending along a first direction. The side of the shaping groove 230 facing the pressing and positioning device 1 is open. The top sealing edge 103 of the battery 101 is adapted to extend into the shaping groove 230 for shaping. Before the battery 101 enters the battery pressure-holding shaping device 10, the top sealing edge 103 of the battery 101 may collapse downwards or tilt upwards. As the shaping module 23 gradually approaches the battery 101, the top sealing edge 103 of the battery 101 moves relative to the open side of the shaping groove 230 to the inner wall of the shaping groove 230 facing away from the pressing and positioning device 1, so that the shape of the top sealing edge 103 of the battery 101 matches the shape of the shaping groove 230, thereby achieving the shaping of the top sealing edge 103 of the battery 101. It should be noted that the shaping module 23 can be a plastic part, for example, the shaping module 23 can be a nylon part.

[0049] In a further embodiment of this utility model, reference is made to the appendix. Figure 3 As shown, the shaping module 23 includes an upper shaping block 231 and a lower shaping block 232. The upper shaping block 231 is located above the lower shaping block 232, and a shaping groove 230 is formed between the upper shaping block 231 and the lower shaping block 232. The end of the lower shaping block 232 near the pressing and positioning device 1 extends beyond the upper shaping block 231. It can be understood that the top sealing edge 103 will contact the lower shaping block 232 first. The lower shaping block 232 can shape the downward-sloping top sealing edge 103, making it rise upward. The shaping module 23 moves towards the pressing and positioning device 1 along the first direction. During the directional movement of the positioning device 1, the top sealing edge 103 will come into contact with the upper shaping block 231. The upper shaping block 231 can shape the upward-curving top sealing edge 103 and press it downward. By making the upper shaping block 231 and the lower shaping block 232 have different lengths in the first direction, the top sealing edge 103 can come into contact with the lower shaping block 232 and the upper shaping block 231 in sequence, avoiding the upper shaping block 231 and the lower shaping block 232 directly blocking the top sealing edge 103, and ensuring that the top sealing edge 103 can smoothly enter the shaping groove 230 for shaping.

[0050] Of course, this utility model is not limited to this. Alternatively, the end of the upper shaping block 231 near the pressing and positioning device 1 can extend beyond the lower shaping block 232, which can also ensure that the top sealing edge 103 can smoothly enter the shaping groove 230 for shaping. However, in the scheme where the end of the lower shaping block 232 near the pressing and positioning device 1 extends beyond the upper shaping block 231, the lower shaping block 232 provides better support for the top sealing edge 103 of the battery 101.

[0051] In a further embodiment of this utility model, reference is made to the appendix. Figure 3 As shown, the upper shaping block 231 has a first guide surface 2311 below the end near the clamping and positioning device 1, in the direction from bottom to top (e.g. Figure 3 As shown, the first guide surface 2311 is inclined towards the pressing and positioning device 1. The presence of the first guide surface 2311 can guide the upward-curved top sealing edge 103, allowing the upward-curved top sealing edge 103 to enter the shaping groove 230 along the extension direction of the first guide surface 2311. This reduces the obstruction effect of the upper shaping block 231 on the top sealing edge 103, ensuring that the top sealing edge 103 can smoothly enter the shaping groove 230. Preferably, the first guide surface 2311 is formed as an arc surface, which can disperse the contact pressure through the geometric characteristics of the curve, avoid stress concentration caused by local high pressure, and protect sensitive components such as the top sealing edge 103 and the tab 104 from mechanical damage.

[0052] Further, see attached document. Figure 3 As shown, the lower shaping block 232 has a second guide surface 2321 above the end near the pressing and positioning device 1. The second guide surface 2321 is inclined towards the pressing and positioning device 1 in a downward direction. The presence of the second guide surface 2321 guides the downward-sloping top sealing edge 103, allowing it to enter the shaping groove 230 along the extension direction of the second guide surface 2321. This reduces the obstruction effect of the lower shaping block 232 on the top sealing edge 103, ensuring that the top sealing edge 103 can smoothly enter the shaping groove 230. Preferably, the second guide surface 2321 is formed as an arc surface, which can disperse contact pressure through the geometric characteristics of the curve, avoiding stress concentration caused by local high pressure and protecting sensitive components such as the top sealing edge 103 and the tab 104 from mechanical damage.

[0053] In a further embodiment of this utility model, reference is made to the appendix. Figure 1 and attached Figure 2As shown, the pressure-holding and shaping device 2 also includes a driving device 24, which is mounted on the first base 21. The driving device 24 drives the pressure-holding module 22 and the shaping module 23 to move along a first direction. When the clamp 20 moves to the battery pressure-holding and shaping device 10, after the clamping and positioning device 1 positions the clamp 20 that holds the battery 101 and drives the clamp 20 to clamp the battery 101, the driving device 24 can drive the pressure-holding module 22 and the shaping module 23 to move along the first direction toward the clamping and positioning device 1, thereby achieving the desired pressure. The side sealing edge 102 of the battery 101 is pressurized and the top sealing edge 103 of the battery 101 is shaped. After the pressurization and shaping are completed, the driving device 24 can drive the pressurization module 22 and the shaping module 23 to move in the first direction away from the pressing and positioning device 1, so that the clamp 20 leaves the battery pressurization and shaping device 10, so as to avoid affecting the movement of the clamp 20. By setting the driving device 24, the position of the pressurization module 22 and the shaping module 23 in the first direction can be controlled to meet different needs.

[0054] In a further embodiment of this utility model, reference is made to the appendix. Figure 1 and attached Figure 2 As shown, the driving device 24 includes a first mounting plate 241, a first driving structure 242, and a second driving structure 243. The first driving structure 242 is mounted on the first mounting plate 241 and is used to drive the pressure holding module 22 and the shaping module 23 to move along a first direction. The second driving structure 243 is mounted on the first base 21 and is used to drive the first mounting plate 241 to move along the first direction. It can be understood that by providing the first driving structure 242 and the second driving structure 243, segmented control can be achieved, the driving force of the driving device 24 can be better adjusted, the pressure applied by the pressure holding module 22 to the battery 101 can be adjusted, the pressure holding effect can be improved, the aluminum-plastic film breakage rate can be reduced, and the production and manufacturing cost of the battery 101 can be reduced. By setting the first mounting plate 241, the installation of the first driving structure 242 can be guaranteed, and the second driving structure 243 can drive the first driving structure 242 to move along the first direction.

[0055] In a specific example, see Appendix Figure 1 and attached Figure 2 As shown, both the first drive structure 242 and the second drive structure 243 are cylinders. The piston rods of both the first drive structure 242 and the second drive structure 243 are movable along the first direction. The pressure holding module 22 is directly connected to one end of the piston rod of the first drive structure 242 facing the pressing and positioning device 1. The pressure holding and shaping device 2 also includes a bracket 25, which is fixed on the piston rod of the first drive structure 242. The two shaping modules 23 are indirectly connected to the piston rod of the first drive structure 242 through the bracket 25.

[0056] The process of the pressure maintaining module 22 and the shaping modules 23 moving in a direction approaching the compression positioning device 1: the piston rod of the second driving structure 243 moves along the first direction toward the compression positioning device 1, and drives the first mounting plate 241 to move along the first direction toward the compression positioning device 1 until the piston rod of the second driving structure 243 cannot continue to move toward the compression positioning device 1, then the piston rod of the first driving structure 242 moves along the first direction toward the compression positioning device 1, and further drives the pressure maintaining module 22, the bracket 25 and the two shaping modules 23 to move toward the battery 101, so as to maintain pressure on the side sealing plate of the battery 101 and shape the top sealing edge 103 of the battery 101.

[0057] The process of the pressure maintaining module 22 and the shaping modules 23 moving in a direction away from the compression positioning device 1: the piston rod of the first driving structure 242 moves along the first direction in a direction away from the compression positioning device 1, and drives the pressure maintaining module 22, the bracket 25 and the two shaping modules 23 to move in a direction away from the battery 101 until the piston rod of the first driving structure 242 cannot continue to move in a direction away from the compression positioning device 1, then the piston rod of the second driving structure 243 moves along the first direction in a direction away from the compression positioning device 1, and drives the first mounting plate 241 and the first driving structure 242 to move in a direction away from the compression positioning device 1.

[0058] Preferably, during the process that the pressure maintaining module 22 maintains pressure on the side sealing edge 102 of the battery 101, an electric proportional valve can be used to control the first driving structure 242, so as to realize stepped control of the pressure maintaining pressure. For example, pressure maintaining can be performed at pressure p1 for t1 time first, then at pressure p2 for t2 time, and finally at pressure p3 for t3 time, where p1<p2<p3. Increasing the pressure in stages can further improve the pressure maintaining effect and reduce the damage rate of the aluminum plastic film. Moreover, the pressure maintaining effect can be further adjusted by combining the temperature of the pressure maintaining module 22.

[0059] Further, with reference to the accompanying Figure 2 as shown, the upper surface of the first base 21 is provided with a first sliding rail 211, the first sliding rail 211 extends along the first direction, the lower surface of the first mounting plate 241 is provided with a first sliding block 2411, the first sliding block 2411 is matched with the first sliding rail 211, and the first sliding block 2411 can move on the first sliding rail 211. Through the matching of the first sliding block 2411 and the first sliding rail 211, a guiding effect can be achieved for the movement of the first mounting plate 241, ensuring accurate linear movement of the first mounting plate 241 and the first driving structure 242, and further ensuring the movement accuracy of the pressure maintaining module 22 and the shaping modules 23 along the first direction.

[0060] In a still further embodiment of the present utility model, with reference to the accompanying Figure 1 and the accompanying Figure 2As shown, the drive device 24 also includes an elastic element 244, which is located between the second drive structure 243 and the first mounting plate 241. The end of the first mounting plate 241 facing the second drive structure 243 has a mating groove 2412, and the elastic element 244 is disposed within the mating groove 2412. The length direction of the elastic element 244 (see attached diagram) Figure 1 One end of the first direction shown abuts against the piston rod of the second drive structure 243, and the other end abuts against the inner wall of the mating groove 2412 opposite to the second drive structure 243.

[0061] Understandably, the elastic element 244 enables a flexible connection between the second drive structure 243 and the first mounting plate 241. When the first drive structure 242 drives the pressure-holding module 22 to abut against the battery 101, the reaction force can be transmitted to the elastic element 244, ensuring that the actual pressure applied to the battery 101 is equal to the elastic force of the elastic element 244, thus preventing excessive pressure on the battery 101 and protecting it. Furthermore, through the cooperation of the first drive structure 242, the second drive structure 243, the first mounting plate 241, and the elastic element 244, three-stage control can be achieved, allowing for better adjustment of the driving force of the drive device 24, adjusting the pressure applied to the battery 101 by the pressure-holding module 22, improving the pressure-holding effect, reducing the breakage rate of the aluminum-plastic film, and lowering the manufacturing cost of the battery 101.

[0062] In a further embodiment of this utility model, reference is made to the appendix. Figure 1 and attached Figure 2 As shown, the second drive structure 243 is a stroke adjustable cylinder. The stroke adjustable cylinder can change the stop position of the piston rod by rotating the adjusting nuts at both ends of the cylinder, thereby achieving linear adjustment of the stroke, adjusting the push-out pressure of the drive device 24, reducing the downtime and modification cost of the battery pressure holding and shaping equipment 10, and improving the flexibility of the production line.

[0063] In some embodiments of this utility model, reference is made to the appendix. Figure 3 As shown, the clamp 20 includes a base 3 and a jaw 4. The jaw 4 is rotatably disposed above the base 3. The battery 101 is adapted to be clamped between the base 3 and the jaw 4. By rotating the jaw 4 on the base 3, the battery 101 can be clamped or released, making the operation of the clamp 20 simple. Furthermore, the clamp 20 also includes a second elastic element disposed between the base 3 and the jaw 4. The second elastic element can drive the base 3 and the jaw 4 to clamp the battery 101, ensuring that the jaw 4 can clamp the battery 101 securely between the base 3 and the jaw 4. At the same time, the clamp 20 has a simple structure, is easy to manufacture, and helps reduce production costs. For example, the second elastic element can be a spring, etc.

[0064] Further, see attached document. Figure 1 and attached Figure 2 As shown, the clamping and positioning device 1 includes a second base 11 and a clamping mechanism 12. The clamping mechanism 12 is disposed on the second base 11 and includes a clamping member 121 and a third driving structure 122. The clamping member 121 is positioned along the vertical direction (e.g., ...). Figure 2 The clamping member 121 (as shown) is movable and used to press the jaw 4 above. The third drive structure 122 is used to drive the clamping member 121 to move up and down. It can be understood that the clamping member 121 can press the jaw 4, making the jaw 4 of the clamp 20 more reliable in clamping the battery 101, avoiding problems such as the battery 101 flipping during the pressure holding and shaping process, and ensuring the reliability and accuracy of the pressure holding and shaping of the battery 101. The third drive structure 122 can drive the clamping member 121 to move in the up and down direction, meeting the movement requirements of the clamping member 121, ensuring reliable pressing of the jaw 4, thereby ensuring reliable limiting of the battery 101, and realizing automation, which helps to reduce manual operation and ensure production efficiency. For example, the clamping member 121 and the third drive structure 122 together form a cylinder, in which the clamping member 121 acts as the piston rod of the cylinder.

[0065] It should be noted that the reference appendix Figure 3 and attached Figure 6 As shown, the claw 4 has a first groove 43 on the side facing the base 3, and the base 3 has a second groove 32 on the side facing the claw 4. The first groove 43 and the second groove 32 are opposite to and connected. The battery 101 is located in the first groove 43 and the second groove 32. By cooperating with the outer peripheral wall of the battery 101 through the first groove 43 and the second groove 32, the contact area between the claw 4 and the base 3 and the battery 101 can be increased, effectively positioning the battery 101 and ensuring reliable positioning of the battery 101.

[0066] Preferably, refer to the appendix Figure 3 and attached Figure 6 As shown, the battery 101 is a cylindrical soft-pack battery 101. On the cross-section perpendicular to the second direction, the first groove 43 and the second groove 32 are both formed into an arc shape, that is, the clamp 20 can be processed to conform to the shape, thereby fitting the battery 101 and achieving precise positioning of the battery 101. This ensures reliable positioning of the battery 101, prevents the battery 101 from rolling within the clamp 20, and ensures that the side sealing edge 102 of the battery 101 is opposite to the pressure holding module 22 and the top sealing edge 103 of the battery 101 is opposite to the shaping module 23, thus ensuring the effectiveness of the battery pressure holding and shaping equipment 10 in maintaining and shaping the battery 101.

[0067] In a further embodiment of this utility model, reference is made to the appendix. Figure 1 and attached Figure 2As shown, the clamping mechanism 12 also includes a second mounting plate 123 and a fourth drive structure 124. A third drive structure 122 and a clamping member 121 are mounted on the second mounting plate 123, and the fourth drive structure 124 is mounted on the second base 11. The fourth drive structure 124 drives the second mounting plate 123 to move along a first direction, causing the clamping member 121 to drive the jaw 4 to rotate and release the battery 101. It can be understood that by controlling the second mounting plate 123 through the fourth drive structure 124, the positions of the third drive structure 122 and the clamping member 121 in the first direction can be indirectly adjusted to allow the clamping member 121 to clamp or release the jaw 4, ensuring the reliability of the battery 101's fixation during the operation of the battery pressure-holding and shaping equipment 10, and ensuring that the clamp 20 can leave the battery pressure-holding and shaping equipment 10 after the pressure-holding and shaping is completed. For example, the fourth drive structure 124 can be a cylinder or a linear motor.

[0068] Further, see attached document. Figure 2 As shown, the upper surface of the second base 11 has a second slide rail 111, which extends along a first direction. The lower surface of the second mounting plate 123 has a second slider 1231, which cooperates with the second slide rail 111 and is movable on the second slide rail 111. Through the cooperation between the second slider 1231 and the second slide rail 111, the movement of the second mounting plate 123 can be guided, ensuring the precise linear movement of the second mounting plate 123, the third drive structure 122, and the clamping member 121.

[0069] In a further embodiment of this utility model, reference is made to the appendix. Figure 3 and attached Figure 6 As shown, the jaw 4 has a driving surface 41 that cooperates with the clamping member 121. When the jaw 4 clamps the battery 101, the driving surface 41 is located above the jaw 4 and is inclined upward in the direction from the pressure-holding and shaping device 2 to the pressure-holding and positioning device 1. The rotation shaft 42 of the jaw 4 is located on the side of the driving surface 41 that is close to the pressure-holding and shaping device 2. The jaw 4 also has a clamping surface 44 that cooperates with the clamping member 121. The clamping surface 44 is located on the side of the rotation shaft 42 of the jaw 4 that is away from the driving surface 41. When the jaw 4 clamps the battery 101, the clamping surface 44 extends in the horizontal direction and the clamping member 121 abuts against the clamping surface 44.

[0070] Understandably, before the pressure holding and shaping, the fourth drive structure 124 drives the second mounting plate 123 to move toward the pressure holding and shaping device 2 along the first direction, and the third drive structure 122 and the clamping member 121 move together toward the pressure holding and shaping device 2 along the first direction until the clamping member 121 and the clamping surface 44 are opposite each other in the vertical direction. Then the third drive structure 122 drives the clamping member 121 to move downward until the clamping member 121 and the clamping surface 44 stop, ensuring that the claw 4 clamps the battery 101.

[0071] After the pressure-holding and shaping process is completed, the third drive structure 122 drives the clamping member 121 to move upward, the clamping member 121 is spaced apart from the clamping surface 44, and the chuck 4 is released. Then, the fourth drive structure 124 drives the second mounting plate 123 to move along the first direction away from the pressure-holding and shaping device 2, which in turn drives the third drive structure 122 and the clamping member 121 to move together along the first direction away from the pressure-holding and shaping device 2 until the clamping member 121 and the drive surface 41 are facing each other in the vertical direction. The third drive structure 122 then drives the clamping member 121 to move downward, the clamping member 121 presses down on the drive surface 41, and the chuck 4 rotates and opens, allowing the operator to remove the battery 101.

[0072] In a further embodiment of this utility model, reference is made to the appendix. Figure 3 As shown, in conjunction with the reference appendix Figure 2 The base 3 has a positioning hole 31 on the side away from the pressure-holding and shaping device 2. The clamping and positioning device 1 also includes a positioning rod 13 and a fifth drive structure 14. The positioning rod 13 extends along the first direction and is movable along the first direction, and is used to insert into the positioning hole 31 to position the clamp 20. The fifth drive structure 14 is set on the second base 11 and is used to drive the positioning rod 13 to move. Due to the inability to achieve the required processing accuracy and considering the processing cost, there is a slight difference in the specific position of the clamp 20 in the second direction when it moves to the battery pressure-holding and shaping device 10. However, by setting the positioning rod 13, it can cooperate with the positioning hole 31 under the drive of the fifth drive structure 14 to achieve the positioning of the base 3 and ensure that the relative position of the clamp 20 and the clamping and positioning device 1 in the second direction is fixed.

[0073] Further, see attached document. Figure 3 As shown, the end of the positioning rod 13 facing the pressure-holding and shaping device 2 has a positioning guide section 131. The positioning guide section 131 is adapted to extend into the positioning hole 31. In the direction from the pressing positioning device 1 to the pressure-holding and shaping device 2, the cross-sectional area of ​​the positioning guide section 131 gradually decreases, thereby playing a guiding role and facilitating the positioning guide section 131 to extend into the positioning hole 31.

[0074] Optionally, the fifth drive structure 14 may be a cylinder, with the piston rod extending along the first direction and movable, and the positioning rod 13 connected to the piston rod of the fifth drive structure 14; alternatively, the fifth drive structure 14 and the positioning rod 13 may together form a cylinder, with the positioning rod 13 serving as the piston rod of the cylinder.

[0075] Optionally, the positioning hole 31 extends through the base 3 along the first direction, thereby reducing the manufacturing difficulty of the base 3.

[0076] In a further embodiment of this utility model, reference is made to the appendix. Figure 1 and attached Figure 4As shown, there are multiple pressure-holding and shaping devices 2 arranged along a horizontal second direction. The clamping component 121, the third drive structure 122, the positioning rod 13, and the fifth drive structure 14 are all corresponding to multiple pressure-holding and shaping devices 2. The second direction is perpendicular to the first direction, which can realize multi-station parallel processing, and realize the positioning, pressure holding, and shaping of batteries 101 on multiple fixtures 20 at the same time. This makes the pressure holding efficiency and shaping efficiency higher, which can improve production efficiency, increase production capacity, realize high-speed operation, and meet the needs of production cycle. For example, it can achieve a cycle of less than or equal to 3 seconds / cell and a production capacity of more than 20PPM (cells / minute).

[0077] In a specific example, see Appendix Figure 1 and attached Figure 4 As shown, there are two pressure-holding and shaping devices 2 arranged along the second horizontal direction. The clamping part 121, the third drive structure 122, the positioning rod 13 and the fifth drive structure 14 are all two corresponding to the two pressure-holding and shaping devices 2, which can realize parallel processing of two stations, and realize the positioning, pressure holding and shaping of the battery 101 on the two fixtures 20 at the same time, thereby improving production efficiency and matching the production cycle.

[0078] This utility model also proposes a processing device 100 having the battery pressure holding and shaping device 10 of the above embodiments.

[0079] like Figure 1 and Figure 2 As shown, the processing equipment 100 according to an embodiment of the present invention includes a fixture 20 and the battery pressure holding and shaping equipment 10 described above.

[0080] Specifically, see the attached document. Figure 1 and attached Figure 2 As shown, the clamp 20 is used to fix the battery 101, ensuring that the battery 101 is reliably fixed and facilitating subsequent processing of the battery 101. The clamp 20 is located between the pressure holding and shaping device 2 and the clamping and positioning device 1, which facilitates the clamping and positioning device 1 to position the clamp 20 and drive the clamp 20 to clamp the battery 101, and facilitates the pressure holding and shaping device 2 to maintain pressure on the side sealing edge 102 of the battery 101 and to shape the top sealing edge 103 of the battery 101.

[0081] According to the processing equipment 100 of this utility model embodiment, the battery pressure holding and shaping equipment 10 is provided. The battery pressure holding and shaping equipment 10 includes a clamping and positioning device 1 and a pressure holding and shaping device 2. The clamping and positioning device 1 is used to position the clamp 20 that fixes the battery 101 and drive the clamp 20 to clamp the battery 101. The pressure holding and shaping device 2 is used to hold pressure on the side sealing edge 102 of the battery 101 and shape the top sealing edge 103 of the battery 101. On the one hand, it can reduce the rebound rate of the aluminum-plastic film, avoid electrolyte leakage, improve the sealing and safety of the battery 101, ensure the quality of the battery 101, and extend the service life of the battery 101. On the other hand, it can uniformly distribute stress, enhance the connection strength between the tab 104 and the cell electrode, extend the electrical connection life, and enable one device to simultaneously hold pressure on the side sealing edge 102 and shape the top sealing edge 103 of the battery 101. This can relatively reduce the production steps of the battery 101, improve the production efficiency of the battery 101, and match the high-speed production cycle.

[0082] In some embodiments of this utility model, reference is made to the appendix. Figure 1 and attached Figure 2 As shown, the processing equipment 100 also includes a conveying mechanism 30. The clamp 20 is connected to the conveying mechanism 30. The conveying mechanism 30 is located between the pressure holding and shaping device 2 and the clamping and positioning device 1. It is used to drive the clamp 20 to move along the horizontal second direction to the battery pressure holding and shaping equipment 10. The first direction and the second direction are perpendicular, so that the clamp 20 can move synchronously with the conveyor line. It can realize dynamic pressure holding and shaping without stopping the line, avoiding the problem of stopping the pressure holding and shaping, making the pressure holding efficiency and shaping efficiency higher, and improving the production capacity. This enables high-speed operation and meets the production cycle requirements. For example, it can achieve a cycle of less than or equal to 3 seconds / piece and a production capacity of more than 20 PPM (pieces / minute).

[0083] Further, see attached document. Figure 1 and attached Figure 2 As shown, the clamp 20 is detachably mounted on the conveying mechanism 30, which facilitates the installation and removal of the clamp 20, as well as maintenance or replacement, and can meet different usage requirements.

[0084] Optionally, there can be multiple clamps 20 (two or more). The first groove 43 and the second groove 32 of the multiple clamps 20 have different shapes and / or sizes. The multiple clamps 20 can be interchangeably disposed on the conveying mechanism 30 to realize the connection between the multiple different clamps 20 and the conveying mechanism 30, thereby realizing the fixing and conveying requirements of batteries 101 of different shapes and / or sizes, enabling the processing equipment 100 to process different batteries 101, facilitating the universality of the processing equipment 100, meeting the processing requirements of different batteries 101, and avoiding the need to replace the entire clamps 20 and the conveying mechanism 30, which can reduce production costs.

[0085] Optionally, the processing equipment 100 according to the present invention can be applied to a battery production line.

[0086] Other configurations and operations of the battery pressure-holding and shaping equipment 10 and the processing equipment 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
