[0035] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1:

[0038] See Figure 1 A hot pressing and cold pressing device for battery cell edge sealing is used to position the battery cell and then perform hot pressing and cold pressing on the battery cell edge sealing positions in sequence to ensure the forming effect of the battery cell edge sealing.

[0039] The hot pressing and cold pressing device includes a cell positioning mechanism 100 , a cell pressing mechanism 200 , a hot pressing mechanism 300 , a cold pressing mechanism 400 and a driving mechanism 500 . The hot pressing mechanism 300 and the cold pressing mechanism 400 are both connected to the driving end of the driving mechanism 500 .

[0040] The battery cell positioning mechanism 100 is used to position the battery cell, the battery cell pressing mechanism 200 is used to press the battery cell onto the battery cell positioning mechanism 100, and the driving mechanism 500 is used to sequentially drive the hot pressing mechanism 300 and the cold pressing mechanism 400 to move to the corresponding battery cell edge sealing positions. The hot pressing mechanism 300 is used for hot pressing of the battery cell edge sealing, and the cold pressing mechanism 400 is used for cold pressing of the battery cell edge sealing.

[0041] The battery cell positioning mechanism 100 can be a contoured groove that matches the shape of the battery cell, which plays a corresponding positioning role for the battery cell. Of course, it can also be adopted to set an adjacent reference edge, and the battery cell can be positioned by pushing the opposite side of the battery cell so that the battery cell contacts the reference edge. This method is adaptable to the positioning of battery cells of various types and sizes. In actual applications, it can be adjusted according to specific needs. The battery cell pressing mechanism 200 is used to press the upper surface of the battery cell from top to bottom after completing the positioning of the battery cell on the battery cell positioning mechanism 100, so as to ensure that the battery cell will not move in position during subsequent hot pressing and cold pressing operations. The driving mechanism 500 is used to drive the hot pressing mechanism 300 and the cold pressing mechanism 400 to move to the battery cell edge sealing position in sequence, first hot pressing the battery cell edge sealing position by the hot pressing mechanism 300, and then cold pressing by the cold pressing mechanism 400.

[0042] During the specific operation, the battery cell is first placed on the battery cell positioning mechanism 100. After the battery cell is positioned by the battery cell positioning mechanism 100, the battery cell pressing mechanism 200 is actuated to press on the upper surface of the battery cell to ensure that the battery cell does not move. Then, the driving mechanism 500 drives the hot pressing mechanism 300 to move to the corresponding battery cell edge sealing position. The hot pressing mechanism 300 hot presses the glue after gluing to melt the glue a second time. Finally, the cold pressing mechanism 400 is driven by the driving mechanism 500 to move to the corresponding battery cell edge sealing position and quickly cold presses the glue that has melted for the second time to ensure the battery cell edge sealing forming effect.

[0043] This embodiment provides a hot pressing and cold pressing device for battery cell edge sealing. By setting a driving mechanism 500, the hot pressing mechanism 300 and the cold pressing mechanism 400 are driven in sequence to perform hot pressing and cold pressing on the glue after gluing, thereby effectively ensuring the molding effect of the battery cell edge sealing. Moreover, before the hot pressing and cold pressing operations are performed on the battery cell edge sealing position, the battery cell positioning mechanism 100 and the battery cell clamping mechanism 200 are used to ensure the accuracy and stability of the battery cell's operating position, thereby further improving the battery cell edge sealing molding effect.

[0044] Example 2:

[0045] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the hot pressing and cold pressing device of the utility model. Figure 2-Figure 4 .

[0046] See also Figure 2 The battery cell positioning mechanism 100 provided in this embodiment includes a positioning groove 110. An opening 120 for exposing the battery cell edge seal is formed on one side of the positioning groove 110 corresponding to the battery cell edge seal. A pushing component 130 for pushing the battery cell toward the opposite side is provided on one side of the positioning groove 110 adjacent to the opening 120, thereby achieving the positioning effect of the battery cell.

[0047] In this example, the battery cell is a rectangular structure, and the structure of the positioning groove 110 matches the structure of the battery cell. The positioning groove 110 is a groove of a rectangular structure. Since the operations of the hot pressing mechanism 300 and the cold pressing mechanism 400 are aimed at the edge sealing position of the battery cell, when positioning the battery cell, it is necessary to consider that the positioning groove 110 will not block or enclose the edge sealing of the battery cell to avoid interfering with the operation of the hot pressing mechanism 300 and the cold pressing mechanism 400. To this end, an opening 120 for exposing the edge sealing of the battery cell is formed on one side of the positioning groove 110 corresponding to the edge sealing of the battery cell. It can be understood that a first reference surface is formed on one side of the positioning groove 110 corresponding to the opening 120 for abutting against the opposite side of the edge sealing of the battery cell to achieve the positioning effect of the battery cell in this direction.

[0048] A pushing component 130 is provided on one side of the positioning groove 110 adjacent to the opening 120. In this example, the pushing component 130 can be an elastic member, which uses its own elastic force to move the battery cell toward the opposite side. It can be understood that a second reference surface is formed on the opposite side of the positioning groove 110 relative to the elastic member for abutting against the side of the battery cell to achieve the positioning effect of the battery cell in this direction.

[0049] See also Figure 3 and Figure 4 In some embodiments, the battery cell clamping mechanism 200 includes a first transverse driving module 210, a first lifting driving module 220 and a first lower pressing block 230, the first lower pressing block 230 is connected to the driving end of the first lifting driving module 220, and the first lifting driving module 220 is connected to the driving end of the first transverse driving module 210.

[0050] After the battery cell is positioned on the battery cell positioning mechanism 100, the first downward pressure block 230 moves laterally to the top of the battery cell under the action of the first transverse driving module 210, and then moves to the upper end of the battery cell under the driving action of the first lifting driving module 220, and generates downward pressure on the upper surface of the battery cell to ensure the positioning stability of the battery cell.

[0051] Furthermore, a first flexible member 240 is provided between the first pressing block 230 and the driving end of the first lifting driving module 220 , and the first flexible member 240 enables flexible contact between the first pressing block 230 and the battery cell to prevent damage to the battery cell due to hard contact.

[0052] Specifically, the first flexible member 240 can be a spring, which is distributed along the driving direction of the first lifting drive module 220. The first end of the spring is connected to the driving end of the first lifting drive module 220, and the other end of the spring is connected to the first lower pressure block 230. When the first lower pressure block 230 moves downward under the action of the first lifting drive module 220 until it contacts the surface of the battery cell, the spring will be squeezed under the continued downward driving action of the first lifting drive module 220, thereby making the contact between the first lower pressure block 230 and the battery cell produce a flexible contact effect, thereby protecting the battery cell.

[0053] Example 3:

[0054] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the hot pressing and cold pressing device of the utility model. Figure 5 and Figure 6 .

[0055] The driving mechanism 500 in this embodiment includes a second lifting driving module 510 and a mounting block 520 connected to the driving end of the second lifting driving module 510; the cold pressing mechanism 400 and the hot pressing mechanism 300 are respectively arranged at the upper and lower ends of the mounting block 520, so that the second lifting driving module 510 can drive the hot pressing mechanism 300 and the cold pressing mechanism 400 to move to the corresponding battery cell edge sealing positions in turn.

[0056] It is understandable that this embodiment is not limited to the cold pressing mechanism 400 being located at the upper end of the mounting block 520, or the hot pressing mechanism 300 being located at the lower end of the mounting block 520. Adjustments can be made according to actual needs. Here, the cold pressing mechanism 400 and the hot pressing mechanism 300 are arranged in an upper and lower spacing manner. The purpose is to facilitate the driving action of the second lifting drive module 510, so that the hot pressing mechanism 300 and the cold pressing mechanism 400 are moved to the corresponding battery cell edge sealing positions in sequence.

[0057] In some embodiments, the hot pressing mechanism 300 includes a second transverse driving module 310 and a hot pressing block 320, the hot pressing block 320 is connected to the driving end of the second transverse driving module 310, and the second transverse driving module 310 is set on the mounting block 520; the cold pressing mechanism 400 includes a third transverse driving module 410 and a cold pressing block 420, the cold pressing block 420 is connected to the driving end of the third transverse driving module 410, and the third transverse driving module 410 is set on the mounting block 520, to realize hot pressing and cold pressing operations on the edge sealing of the battery cell.

[0058] When the hot pressing mechanism 300 moves to the corresponding battery cell edge sealing position under the action of the driving mechanism 500, the hot pressing block 320 extends toward the battery cell edge sealing direction under the driving action of the second transverse driving module 310, and produces a pressing effect on the battery cell edge sealing, thereby producing a secondary melting effect on the glue after gluing; immediately afterwards, the driving mechanism 500 drives the cold pressing mechanism 400 to move to the corresponding battery cell edge sealing position, and the cold pressing block 420 extends toward the battery cell edge sealing direction under the driving action of the third transverse driving module 410, and performs rapid cold pressing on the battery cell edge sealing.

[0059] Furthermore, a second flexible member 330 is provided between the hot pressing block 320 and the driving end of the second transverse driving module 310 ; and a third flexible member 430 is provided between the cold pressing block 420 and the driving end of the third transverse driving module 410 .

[0060] The second flexible member 330 and the third flexible member 430 can both be springs, and the second flexible member 330 is distributed along the driving direction of the second transverse driving module 310, and the third flexible member 430 is distributed along the driving direction of the third transverse driving module 410. After the hot pressing block 320 presses the edge sealing position of the battery cell under the driving action of the second transverse driving module 310, under the continued driving action of the second transverse driving module 310, the second flexible member 330 is compressed to ensure the flexible contact between the hot pressing block 320 and the edge sealing of the battery cell; similarly, after the cold pressing block 420 presses the edge sealing position of the battery cell under the driving action of the third transverse driving module 410, the third flexible member 430 is compressed to ensure the flexible contact between the cold pressing block 420 and the edge sealing of the battery cell under the continued driving action of the third transverse driving module 410, thereby preventing hard contact from damaging the battery cell.

[0061] Furthermore, a transverse guide assembly 340 is provided between the hot pressing block 320 and the driving end of the second transverse driving module 310 to ensure the stability of the moving path of the hot pressing block 320, thereby ensuring the hot pressing effect.

[0062] The transverse guide assembly 340 may include a sliding block and a slide rail. The slider is connected to the drive end of the second transverse drive module 310, while the slide rail is provided on the hot pressing block 320. When the second transverse drive module 310 drives the hot pressing block 320 to move laterally, the hot pressing block 320 can contact the sliding guide of the slide rail and the slider, allowing for stable movement. Similarly, a transverse guide assembly 340 may also be provided between the cold pressing block 420 and the drive end of the third transverse drive module 410 to serve as a movement guide.

[0063] In some embodiments, a heating tube 350 is embedded along the length direction of the hot pressing block 320 on one side close to the battery cell sealing edge; a vortex tube 440 is embedded along the length direction of the cold pressing block 420 on one side close to the battery cell sealing edge. The heating tube 350 heats up the hot pressing block 320, and the vortex tube 440 cools down the cold pressing block 420.

[0064] It can be seen that the edge sealing of the battery cell has a certain length. In order to achieve a better secondary melting effect on the glue at the edge sealing position of the battery cell, a heating tube 350 is embedded along the length direction of the hot pressing block 320 close to the edge sealing of the battery cell. The heating tube 350 heats the hot pressing block 320, thereby utilizing the temperature of the hot pressing block 320 to melt the glue for the second time. Similarly, the vortex tube 440 is utilized to cool the cold pressing block 420, thereby enabling the glue to be quickly cold-pressed and formed.

[0065] It can be understood that in this embodiment, the heating component embedded in the hot pressing block 320 is not limited to the heating tube 350, but can also be other components that can play a heating role. Similarly, the cooling component embedded in the cold pressing block 420 is not limited to the vortex tube 440, but can also be other components that can play a cooling role.

[0066] Furthermore, the hot pressing block 320 is also connected to a temperature controller 360 , which facilitates monitoring the temperature of the hot pressing block 320 to prevent damage to the battery cell edge seal due to excessive temperature, thereby ensuring the quality of the operation.

[0067] The utility model provides a hot pressing and cold pressing device for battery cell edge sealing, which drives the hot pressing mechanism and the cold pressing mechanism to move to the corresponding battery cell edge sealing positions in sequence through a driving mechanism, and performs hot pressing and cold pressing on the battery cell edge sealing, thereby achieving the purpose of hot pressing the glue after gluing at the battery cell edge sealing position, melting the glue a second time, and then quickly cold pressing and forming, thereby ensuring the battery cell edge sealing forming effect. In addition, before the battery cell edge sealing position is subjected to hot pressing and cold pressing operations, the battery cell positioning mechanism and the battery cell clamping mechanism are used to ensure the accuracy and stability of the battery cell operating position, thereby further improving the battery cell edge sealing forming effect.
