[0014] The technical solution of the present utility model will be explained in more detail below with reference to the drawings and on the basis of specific embodiments.

[0015] As in the Fig. 1 to Fig.As shown in Figure 4, the present embodiment provides a battery cover plate forming device. The battery cover plate forming device comprises a support platform 100, a stop module 300, a first forming module, and a second forming module.The support platform 100 serves to support an element 1 to be formed, wherein the element 1 to be formed comprises a base body 11 and a part 12 to be formed; the stop module 300 can move along the X-direction and rests against the base body 11; the first forming module comprises an outer forming element 210, wherein the outer forming element 210 can move along the Y-direction to rest against one side of the part 12 to be formed; the second forming module comprises an inner forming element 220, wherein the inner forming element 220 can move along the Y-direction to rest against the other side of the part 12 to be formed, wherein the inner forming element 220 and the outer forming element 210 can form a forming space to shape the part 12 to be formed.

[0016] The arrangement of the support platform 100 allows it to support the element 1 to be formed; the arrangement of the stop module 300 enables it to move along the X-direction and abut the base body 11 to achieve positioning and securing of the element 1 to be formed; the arrangement of the first and second forming modules allows them to form the part 12 to be formed. Specifically, the first forming module comprises an outer forming element 210, which can abut one side of the part 12 to be formed, and an inner forming element 220, which can abut the other side of the part 12 to be formed. Simultaneously, the outer forming element 210 and the inner forming element 220 move along the Y-direction.Therefore, the part 12 to be formed can be pressed and thus formed simultaneously on both sides within the forming space if the outer forming element 210 and the inner forming element 220 form a forming space along the Y-direction, thereby preventing deformation of the part 12 to be formed from leading to defective products in subsequent production and increasing the production yield.

[0017] For example, the base body 11 is a cover plate and the part to be formed 12 is an adapter plate, wherein the adapter plate is in a right-angled state, one end is welded to the cover plate and the other end is perpendicular to the cover plate. The adapter plate formed by the battery cover plate forming device can maintain its right-angled state, thereby increasing the reliability of the connection between the adapter plate and the electrode tab and the terminal. Furthermore, it ensures that after welding to the cell, the adapter plate can be installed in the housing during subsequent assembly without colliding with the housing, thus increasing assembly efficiency.

[0018] Preferably, the outer forming element 210 has a first forming surface that is parallel to both the base body 11 and the part 12 to be formed, and the inner forming element 220 has a second forming surface that is parallel to both the base body 11 and the part 12 to be formed. This allows the outer forming element 210 and the inner forming element 220 to simultaneously bear against both the part 12 to be formed and the base body 11, ensuring the shape and verticality of the part 12 to be formed and simultaneously pressing the connection between the part 12 to be formed and the element 1 to be formed, thereby increasing the reliability of the connection between the part 12 to be formed and the element 1 to be formed.

[0019] In this embodiment, the battery cover plate forming device further comprises a base plate 400, wherein the support platform 100, the stop module 300, the first forming module, and the second forming module are all provided on the base plate 400. The base plate 400 facilitates an increase in the level of integration of the battery cover plate forming device. For example, the battery cover plate forming device can be positioned downstream of a welding fixture for the part to be formed, in order to form the welded part 12 to be formed.

[0020] Specifically, the first forming module further comprises a first drive arrangement provided on the support platform 100, wherein the first drive arrangement includes a first drive element 232, at the drive end of which an outer forming element 210 is provided, and the first drive arrangement can drive the outer forming element 210 so that it moves along the Y-direction; furthermore, the first drive arrangement has a first guide rail 231 and a first slide 233, wherein the first guide rail 231 extends along the Y-direction, the first slide 233 is slidably provided on the first guide rail 231, and the outer forming element 210 is connected to the first slide 233. The arrangement of the first guide rail 231 and the first slide 233 provides guidance for the movement of the outer forming element 210, thus increasing the accuracy of its movement.In other embodiments, the first slide 233 can also be omitted, and the outer shaping element 210 can be provided in such a way that it is slidably connected to the first guide rail 231 in order to further simplify the structure.

[0021] The second forming module also includes a second drive assembly, which is provided on the support platform 100. The inner forming element 220 is located at the drive end of the second drive assembly, and the second drive assembly can drive the inner forming element 220 so that it moves along the Y-direction. The second drive assembly further comprises a second guide rail 242 and a second carriage 243, wherein the second guide rail 242 extends along the Y-direction, the second carriage 243 is slidably mounted on the second guide rail 242, and the inner forming element 220 is connected to the second carriage 243. Optionally, the first drive element 232, the second drive element 241, the first guide rail 231, and the second guide rail 242 are all provided on the base plate 400.

[0022] It is worth noting that the battery cover plate forming device further comprises a control unit, wherein the first drive element 232 and the second drive element 241 are communicatively connected to the control unit. In controlling the drive elements, the control unit can simultaneously ensure synchronization between them, thus enabling more precise and reliable press forming of the part 12 to be formed.

[0023] In this embodiment, a part 12 to be formed is provided at both ends of the base body 11. Therefore, two outer forming elements 210 and two inner forming elements 220 are provided to form the parts 12 to be formed. Accordingly, two second drive elements 241 are provided to drive the inner forming elements 220. The first drive element 232 is provided once and drives the two outer forming elements 210 synchronously via a synchronization structure, which simplifies the structure.

[0024] In this embodiment, the stop module 300 comprises a positioning aperture 310, wherein the positioning aperture 310 is provided on the support platform 100 and has a contact surface that can abut the base body 11, and the element 1 to be formed can abut the contact surface of the positioning aperture 310. By means of the arrangement of the positioning aperture 310, it serves to position the element 1 to be formed on the support platform 100, thus increasing the accuracy of the position of the outer forming element 210 and the inner forming element 220 relative to the part 12 to be formed.

[0025] For example, the stop module 300 has a third drive assembly and a positioning element 330, wherein the positioning element 330 is provided at the drive end of the third drive assembly, and the third drive assembly can drive the positioning element 330 along the X-direction so that it rests against the side of the base body 11 furthest from the positioning aperture 310. The positioning element 330 is provided and simultaneously driven by the third drive assembly, and the base body 11 is pressed between the positioning element 330 and the positioning aperture 310. This allows the stop module 300 not only to position the base body 11 but also to secure it, thus preventing the base body 11 from slipping and the forming process from failing when the part 12 to be formed is subsequently pressed. This increases the reliability of the battery cover plate forming device.

[0026] It is worth noting that the orthogonal projection of the positioning piece 330 onto the contact surface overlaps at least partially with the contact surface. This means that the positioning and fastening of the base body 11 is made possible by the mutual pressing action of the positioning piece 330 and the positioning disc 310, thereby preventing the tendency for the base body 11 to bend due to the force exerted by the positioning piece 330 and the positioning disc 310.

[0027] Preferably, more than two positioning plates 310 are provided, with the more than two positioning plates 310 being spaced apart in the Y-direction. Likewise, more than two positioning pieces 330 are provided, so that the element 1 to be formed can be attached at more than two positions in the longitudinal direction. This makes the attachment more reliable, and at the same time, the element 1 to be formed is subjected to a more even load, thus preventing damage to the element 1 to be formed due to a load at a single point. In this embodiment, two positioning plates 310 are provided, with the two positioning plates 310 being positionally adjustable in the Y-direction. Two positioning pieces 330 are provided, with the two positioning pieces 330 being positionally adjustable in the Y-direction to accommodate different lengths of the base body 11.

[0028] Specifically, the third drive arrangement comprises a connecting plate 322, which serves to mount two or more positioning elements 330. In this embodiment, the support platform 100 is provided in two parts, with the outer shaping element 210 located at the end of the split support platform 100 that is farther away from the other part. The positioning aperture 310 is also provided on the split support platform 100. Therefore, the position of the positioning aperture 310 moves synchronously when the first drive arrangement drives the split support platform 100 and the outer shaping element 210, causing them to move. Therefore, the two positioning elements 330 are preferably provided to be positionally adjustable on the connecting plate 322 in order to adapt to changes in the position of the positioning aperture 310.Optionally, one end of the positioning piece 330, which is connected to the connecting plate 322, has an elongated hole 331 extending in the Y-direction. A mounting opening 3221 is provided on the connecting plate 322, and the positioning piece 330 can be adjusted by the alignment of the different positions between the mounting opening 3221 and the elongated hole 331.

[0029] The third drive arrangement further comprises a third drive element 321, which serves to drive the connecting plate 322 so that it moves in the X-direction to enable the fitting of the more than two positioning plates 310 with the positioning pieces 330. Optionally, the third drive arrangement also includes a third guide rail 323 and a third carriage. The third guide rail 323 extends in the X-direction, and the third carriage is slidably mounted on the third guide rail 323. The connecting plate 322 is connected to the third carriage.

[0030] Preferably, the stop module 300 further comprises a first measuring element 340, wherein the first measuring element 340 serves to measure the force acting on the base body 11 through the positioning orifice 310 and / or the positioning piece 330 in order to prevent incorrect or excessive pressing of the positioning piece 330 onto the element 1 to be formed. This not only enables proper fastening but also prevents the element 1 to be formed from being damaged by the contact pressure. For example, the third drive element 321 and the first measuring element 340 are all connected to the control unit via communication, which increases the automation of the battery cover plate forming device. Optionally, the first measuring element 340 can be designed as a force sensor. When the value detected by the force sensor reaches a preset value, the control unit can stop the movement of the third drive element 321.Alternatively, the first measuring element 340 can also be used as a proximity switch.

[0031] In other embodiments, a second measuring element can also be provided at a corresponding position to measure the force acting on the element 1 to be formed by the outer forming element 210 and / or the inner forming element 220. This second measuring element is connected to the control unit via communication. The embodiment of the second measuring element can be based on the embodiment of the first measuring element 340 described above and is not explained in detail here.

[0032] The forming process of the battery cover plate forming device described above is as follows: The element 1 to be formed is placed on the carrier platform 100, and one side of the base body 11 is positioned against the positioning aperture 310. The third drive assembly drives the positioning element 330 so that it approaches the positioning aperture 310 along the X-direction. When the first measuring element 340 detects the preset value, the third drive assembly stops the drive, thus completing the positioning and securing of the base body 11. The first drive assembly drives the two outer forming elements 210 toward each other, and the second drive assembly drives the two inner forming elements 220 away from each other to create a forming chamber in which the part 12 to be formed is shaped by compression. The completion of the forming process can be determined by the reading of the second measuring element.It is worth noting that the first drive assembly and the second drive assembly can be driven sequentially or simultaneously. This can be adjusted by specialists in this field according to actual requirements and is not further restricted here.
