Specific embodiments

[0025] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] As shown in Figures 1 and 2, an embodiment of the present application provides a gluing mechanism, which includes: a platform; a gluing component connected to the platform, one end of the gluing component is provided with an adsorption component and a groove 7, and when the adsorption component adsorbs the adhesive paper 100, the adhesive paper 100 is arranged corresponding to the groove 7; an anti-sticking component 3, connected to the platform and located on one side of the gluing component, the anti-sticking component 3 can reach a position opposite to the groove 7, and after the adsorption component adsorbs the adhesive paper 100, it can squeeze the adhesive paper 100 into the groove 7 to form a redundant portion 101 on the adhesive paper 100.

[0027] As shown in Figures 1 and 2, the adhesive application mechanism in the embodiment of the present application includes a platform, an adhesive application assembly, and an anti-adhesion assembly 3. The adhesive application assembly and the anti-adhesion assembly 3 are connected to the platform, and the platform supports the adhesive application assembly and the anti-adhesion assembly 3. The platform can be a support plate or a support base. In the embodiment of the present application, there are no excessive restrictions on the specific type of platform; any platform that can support the adhesive application assembly and the anti-adhesion assembly 3 can be used.

[0028] The adhesive component is connected to the platform, and one end of the adhesive component is provided with an adsorption component and a groove 7. When the adhesive tape 100 is placed on one end of the adhesive component, the adsorption component can adsorb the adhesive tape 100 so that the adhesive tape 100 is arranged opposite to the groove 7.

[0029] For example, the adsorption assembly may include adsorption holes and a negative pressure device, with the adsorption holes being located at one end of the adhesive assembly, and the negative pressure device being connected to the adsorption holes. The adhesive tape 100 is placed on the adsorption holes, and the negative pressure device generates negative pressure to adsorb the adhesive tape 100 to the end of the adhesive assembly. Multiple adsorption holes may be provided, spaced apart at one end of the adhesive assembly and connected to the negative pressure device. The adhesive tape 100 is adsorbed to the end of the adhesive assembly through the multiple adsorption holes, thereby improving the reliability of the adsorption assembly in adsorbing the adhesive tape 100.

[0030] Wherein, the anti-sticking component 3 is connected to the platform, and is positioned at one side of the glue assembly, and the anti-sticking component 3 can reach a position relative to the groove 7. Specifically, the anti-sticking component 3 can be movably connected to the platform, and the glue assembly can be fixedly connected to the platform, and the anti-sticking component 3 is moved to a position relative to the groove 7. The glue assembly can also be movably connected to the platform, and the anti-sticking component 3 can be fixedly connected to the platform, by moving the glue assembly, so that the groove 7 is relative to the anti-sticking component 3. Of course, the anti-sticking component 3 and the glue assembly can also be movably connected to the platform, and the anti-sticking component 3 and the glue assembly can be close to each other so that the groove 7 and the anti-sticking component 3 are relatively arranged. To this end, the present application embodiment is not specifically limited, and in actual use, the technician can set it as needed.

[0031] When the adsorption assembly adsorbs the adhesive tape 100, the anti-adhesion assembly 3 can squeeze the adhesive tape 100 into the groove 7 to form a redundant portion 101 on the adhesive tape 100. Exemplarily, the anti-adhesion assembly 3 may include an anti-adhesion rod. When the adsorption assembly adsorbs the adhesive tape 100, the anti-adhesion rod can squeeze the adhesive tape 100 into the groove to form a redundant portion 101 on the adhesive tape 100.

[0032] The present application provides a glue-applying assembly, comprising a platform; a glue-applying assembly connected to the platform, with an adsorption assembly and a groove 7 spaced apart at one end of the glue-applying assembly. When the adsorption assembly adsorbs adhesive tape 100, the adhesive tape 100 is positioned corresponding to the groove 7; and an anti-adhesion assembly 3 connected to the platform and located on one side of the glue-applying assembly. The anti-adhesion assembly 3 is capable of reaching a position opposite the groove 7. After the adsorption assembly adsorbs the adhesive tape 100, the anti-adhesion assembly 3 is capable of squeezing the adhesive tape 100 into the groove 7, thereby forming a redundant portion 101 on the adhesive tape 100. The adhesive tape 100 with the redundant portion 101 is applied between the connecting piece 400 and the battery cell 200. When the cells are closed or the battery cells expand, the redundant portion 101 can increase the redundancy of the adhesive tape 100, thereby preventing the adhesive tape 100 from pulling on the connecting piece 400 and the tab 300, thereby improving safety performance.

[0033] As an optional embodiment, as shown in Figures 1 and 2, the glue component includes a base 6, a first glue component 1 and a second glue component 2, the base 6 is movably connected to the platform, the first glue component 1 and the second glue component 2 are both connected to the base 6, and the first glue component 1 and the second glue component 2 are spaced apart to form a groove 7 between the first glue component 1 and the second glue component 2.

[0034] As shown in Figures 1 and 2, the base 6 in the embodiment of the present application is movably connected to the platform, and the first adhesive component 1 and the second adhesive component 2 are connected to the base 6. The first adhesive component 1 and the second adhesive component 2 are spaced apart to form a groove 7 between the first adhesive component 1 and the second adhesive component 2.

[0035] Among them, the first adhesive component 1 can be fixedly connected to the base 6, and the second adhesive component 2 can be slidably connected to the base 6, so that the size of the groove 7 can be changed by sliding the second adhesive component 2, thereby changing the size of the redundant part 101. The second adhesive component 2 can also be fixedly connected to the base 6, and the first adhesive component 1 can be slidably connected to the base 6, so that the size of the groove 7 can be changed by sliding the first adhesive component 1, thereby changing the size of the redundant part 101. Of course, the first adhesive component 1 and the second adhesive component 2 can also be slidably connected to the base 6, so that the size of the groove 7 can be changed by the relative sliding of the first adhesive component 1 and the second adhesive component 2, thereby changing the size of the redundant part 101. In this regard, the embodiments of the present application are not specifically limited.

[0036] As an optional embodiment, as shown in Figures 1 and 2, the adsorption component includes a first adsorption component 11 and a second adsorption component 21. The first adsorption component 11 is arranged at the end of the first adhesive component 1 facing away from the base 6, and the second adsorption component 21 is arranged at the end of the second adhesive component 2 facing away from the base 6; when the adsorption component adsorbs the adhesive paper 100, the first adsorption component 11 adsorbs one end of the adhesive paper 100, and the second adsorption component 21 adsorbs the other end of the adhesive paper 100, and the middle part of the adhesive paper 100 corresponds to the groove 7.

[0037] In the embodiment of the present application, as shown in Figures 1 and 2, a first adsorption member 11 is provided at the end of the first adhesive component 1 facing away from the base 6, and a second adsorption member 21 is provided at the end of the second adhesive component 2 facing away from the base 6. When the adsorption members adsorb the adhesive tape 100, the first adsorption member 11 adsorbs one end of the adhesive tape 100, and the second adsorption member 21 adsorbs the other end of the adhesive tape 100, so that the middle portion of the adhesive tape 100 corresponds to the groove 7. The anti-sticking component 3 can squeeze the middle portion of the adhesive tape 100 into the groove 7, thereby forming a redundant portion 101 in the middle portion of the adhesive tape 100.

[0038] It should be noted that the first adsorption member 11 and the second adsorption member 21 in the embodiment of the present application can be adsorption holes, suction cups, or any other adsorption members that facilitate adsorption of the adhesive tape 100. In the embodiment of the present application, there are no excessive restrictions on the specific structures of the first adsorption member 11 and the second adsorption member 21. In actual use, technicians can configure them as needed.

[0039] As an optional embodiment, as shown in Figures 1 and 2, the adsorption assembly also includes: a throttle valve 5 connected to the base 6; the first adsorption part 11 and the second adsorption part 21 are both adsorption holes, and the throttle valve 5 is connected to the first adsorption part 11 and the second adsorption part 21.

[0040] The adsorption assembly in the embodiment of the present application further includes a throttle valve 5, which is connected to the base 6. The first adsorption member 11 and the second adsorption member 21 are both configured as adsorption holes, and the throttle valve 5 is connected to the first adsorption member 11 and the second adsorption member 21, so that the adsorption holes can be evacuated through the throttle valve 5 to adsorb the adhesive tape 100 to the end of the first adhesive component 1 facing away from the base 6 and the end of the second adhesive component 2 facing away from the base 6, thereby fixing the adhesive tape 100 and preventing the adhesive tape 100 from detaching from the adhesive component during the production process of the redundant portion 101.

[0041] As an optional embodiment, as shown in Figures 1 and 2, the second adhesive component 2 is fixedly connected to the base 6; the adhesive mechanism has a first direction A and a second direction B that intersect each other, and the first adhesive component 1 is slidably connected to the base 6 and can slide along the first direction A and the second direction B. In this embodiment, the first direction A is the length direction of the adhesive mechanism, and the second direction B is the height direction of the adhesive mechanism.

[0042] As shown in Figures 1 and 2, in the embodiment of the present application, the second adhesive component 2 is fixedly connected to the base 6, and the first adhesive component 1 is slidably connected to the base 6, and the first adhesive component 1 can slide along a first direction A and a second direction B. The first direction A intersects with the second direction B. Preferably, the first direction A is perpendicular to the second direction B. The following description takes the case where the first direction A is perpendicular to the second direction B as an example.

[0043] The first adhesive component 1 of the embodiment of the present application slides along the first direction A, which can change the distance between the first adhesive component 1 and the second adhesive component 2, thereby changing the size of the groove 7 and further changing the size of the redundant portion 101 on the adhesive tape 100.

[0044] In the embodiment of the present application, the first adhesive component 1 can slide along the second direction B to change the height of the first adhesive component 1. As shown in Figure 3, before adhesive application, after the battery cell 200 and the connecting piece 400 are placed horizontally in place, the battery cell 200 and the connecting piece 400 are at different heights. During adhesive application, the driving base is moved or the clamp holding the battery cell 200 and the connecting piece 400 is driven to move, so that the adhesive component moves toward the battery cell 200 and the connecting piece 400 until the first adhesive component 1 and the second adhesive component 2 respectively abut the battery cell 200 and the connecting piece 400. It can be understood that due to the different heights of the battery cell 200 and the connecting piece 400, during adhesive application, the first adhesive component 1 will first abut the battery cell 200. Then, during the process of continuing to move until the second adhesive component 2 abuts the connecting piece 400, in order to avoid the first adhesive component 1 from causing compression damage to the battery cell 200, the first adhesive component 1 is configured to slide along the second direction B to improve product yield.

Under the drive of the main body of the first cylinder 41, the driving rod of the first cylinder 41 slides relative to the main body of the first cylinder 41, thereby driving the connecting plate 15 to approach or move away from the second gluing component 2 through the connecting block, thereby changing the size of the groove 7, so that the gluing component can glue battery cells of different specifications.

[0047] As an optional embodiment, as shown in Figure 2, the first rubber component 1 also includes: a fixed seat 43 and a buffer 42, wherein the fixed seat 43 is connected to the base 6, the buffer 42 is connected to the fixed seat 43, and one end of the buffer 42 is located between the main body and the connecting block. The buffer 42 can buffer and limit the sliding of the connecting plate 15 when the first cylinder 41 drives the connecting plate 15 to approach the second rubber component 2.

[0048] As shown in Figure 2, in an embodiment of the present application, the fixing seat 43 is connected to the base 6, the buffer 42 is connected to the fixing seat 43, and one end of the buffer 42 is arranged between the main body and the connecting block, so that when the first cylinder 41 drives the connecting plate 15 to approach the second rubber component 2, the buffer 42 buffers and limits the sliding of the connecting plate 15, so that there is a corresponding distance between the second rubber component 2 and the first rubber component 1, avoiding collision between the first rubber component 1 and the second rubber component 2.

[0049] As an optional embodiment, as shown in Figures 1 and 2, the first glue component 1 also includes: a first glue plate 14, a slider 13 and a linear guide 12, wherein the slider 13 is fixedly connected to the connecting plate 15, the linear guide 12 extends along the second direction B and is arranged on the first glue plate 14, and the slider 13 is slidably connected to the linear guide 12; the adsorption component is arranged at the end of the first glue plate 14 away from the base 6, and the first cylinder 41 can drive the connecting plate 15 to move, thereby driving the first glue plate 14 to approach or move away from the second glue component 2.

[0050] In the embodiment of the present application, as shown in Figures 1 and 2, the slider 13 is fixedly connected to the connecting plate 15, the linear guide 12 is disposed on the first adhesive plate 14, and the linear guide 12 extends along the second direction B, and the linear guide 12 is slidably connected to the slider 13. The adsorption assembly is disposed at the end of the first adhesive plate 14 facing away from the base 6. Specifically, the first adsorption member 11 is disposed at the end of the first adhesive plate 14 facing away from the base 6.

The spring extends along the second direction B, with one end of the spring connected to the spring stopper 16 and the other end connected to the first adhesive plate 14. In the embodiment of the present application, it is understood that the arrangement of the spring stopper 16 and the spring allows the first adhesive plate 14 to automatically rebound along the second direction B, returning to its initial position. Specifically, due to the different heights of the battery cells 200 and the connecting plate 400, during adhesive application, the first adhesive plate 14 initially abuts the battery cells 200. Subsequently, as the second adhesive assembly 2 continues to abut the connecting plate 400, the battery cells 200 press against the first adhesive plate 14, causing it to move in the opposite direction of the second direction B, thereby compressing the spring. After adhesive application is complete, the first adhesive plate 14 moves away from the battery cells 200, at which point the spring provides a restoring force, pushing the first adhesive plate 14 back to its initial position.

The anti-adhesion assembly 3 can also be connected to the mobile assembly, so that the anti-adhesion assembly 3 is driven to move by the mobile assembly so that the anti-adhesion assembly 3 reaches a position relative to the groove 7. Of course, the gluing assembly and the anti-adhesion assembly 3 can also be connected to the mobile assembly, so that the gluing assembly and the anti-adhesion assembly are driven to move by the mobile assembly so that the anti-adhesion assembly 3 and the groove 7 are relative.
