Description

Technical Field

[0001] This utility model relates to the technical field of battery production equipment, and in particular to the electrode insulating cap assembly mechanism. Background Technology

[0002] The positive and negative terminals of the battery must be strictly insulated to avoid short circuits caused by internal or external contact.

[0003] To better protect the battery terminals, insulating caps are usually installed on the battery terminals (such as the top of cylindrical batteries or the tabs of prismatic batteries) to block the direct contact between the battery's metal parts and the external environment, preventing the risk of short circuits caused by collisions, squeezing, or foreign object intrusion.

[0004] In related technologies, the tabs need to be bent before the insulating cap is assembled, so that the tabs are bent into three segments that are connected vertically in sequence, and then the insulating cap is put on to complete the assembly of the insulating cap.

[0005] However, the current insulating cap assembly mechanism can cause misalignment between the insulating cap and the battery cell electrode due to the offset position of the electrode after bending. This results in the electrode and the insulating cap being squeezed together during the assembly process, causing deformation of the battery cell electrode. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an electrode tab insulating cap assembly mechanism, which can prevent the electrode tab from shifting position after bending and avoid deformation of the battery cell electrode tab caused by squeezing between the electrode tab and the insulating cap during assembly.

[0007] The electrode insulating cap assembly mechanism according to an embodiment of the present utility model includes:

[0008] The first clamping assembly includes a first clamping component and a second clamping component;

[0009] The second clamping assembly includes a third clamping element and a fourth clamping element, wherein the third clamping element and the fourth clamping element are respectively closed with the first clamping element and the second clamping element to bend the electrode lug;

[0010] The feeding module is used to insert the insulating cap into the bent electrode tab;

[0011] In this process, the second pressing component and the fourth pressing component, and the first pressing component and the third pressing component are separated in sequence. When the feeding module puts the insulating cap into the first electrode tab, the first pressing component and the third pressing component keep pressing and fixing the electrode tab.

[0012] The electrode insulating cap assembly mechanism according to the embodiment of this utility model has at least the following beneficial effects:

[0013] This invention features a first and second pressing component in the first pressing assembly, and a third and fourth pressing component in the second pressing assembly. After the third and fourth pressing components are respectively joined with the first and second pressing components to complete the bending of the electrode tab, the second and fourth pressing components, and the first and third pressing components, separate sequentially. It can be understood that after the first and second pressing assemblies complete the bending of the electrode tab, the second and fourth pressing components separate first, allowing them to move away from the electrode tab and avoid the insulating cap. Then, the feeding module delivers the insulating cap. The cap is inserted into the first section of the electrode tab, which is the part of the electrode tab that is loosened by the second and fourth clamping components. At this time, the first and third clamping components still keep the electrode tab pressed and fixed, so that the bent electrode tab will not shift in position when the insulating cap is inserted into the first section. Then, after the insulating cap is inserted into the first section of the electrode tab, the first and third clamping components separate, and the feeding module continues to completely insert the insulating cap into the electrode tab. This prevents the bent electrode tab from shifting in position, improves the assembly accuracy of the electrode tab and the insulating cap, and avoids the electrode tab of the battery cell being deformed due to squeezing between the electrode tab and the insulating cap during the assembly of the insulating cap.

[0014] According to some embodiments of the present invention, the first pressing member and the second pressing member can move relative to each other in the direction of approaching and moving away from the second pressing assembly, and the second pressing member moves relative to the first pressing member away from the second pressing assembly to disengage from the electrode tab.

[0015] The advantage of this invention is that by enabling the first pressing member and the second pressing member to move relative to each other in the direction of approaching and moving away from the second pressing assembly, and by enabling the second pressing member to move relative to the first pressing member away from the second pressing assembly to disengage from the electrode tab, the second pressing member and the first pressing member can disengage from the electrode tab sequentially, thus avoiding the loss of fixation of the electrode tab position due to the first pressing member and the second pressing member disengaging from the electrode tab at the same time.

[0016] According to some embodiments of the present invention, the first pressing component and the second pressing component are arranged vertically. When the first pressing component rises, it causes the second pressing component to move relative to the first pressing component away from the second pressing component so as to disengage from the electrode tab.

[0017] The advantages of this invention are: by setting the first pressing component and the second pressing component vertically, the first pressing component rises and drives the second pressing component to move relative to the first pressing component away from the second pressing component to disengage from the electrode tab. It can be understood that after the second pressing component, the first pressing component, and the second pressing component close together to complete the bending of the electrode tab, the first pressing component rises and drives the second pressing component to rise synchronously. At this time, the first pressing component is affected by its own gravity and keeps in cooperation with the second pressing component to press and fix the electrode tab. Thus, the first pressing component can keep pressing and fixing the electrode tab when the feeding module puts the insulating cap into the first electrode tab, avoiding the electrode tab from being displaced and causing the electrode tab to be squeezed and damaged by the insulating cap.

[0018] According to some embodiments of the present invention, the first pressing component includes a first spring, which is used to press the first pressing member toward the second pressing component. When the first pressing component moves away from the second pressing component, the first spring presses the first pressing member to keep it pressed and fixed with the second pressing component.

[0019] The advantages of this invention are: by setting a first spring, the first spring is used to press the first pressing component towards the second pressing component. When the first pressing component moves away from the second pressing component, the first spring presses the first pressing component to keep it pressed and fixed with the second pressing component to secure the electrode tab. It can be understood that after the second pressing component, the first pressing component, and the second pressing component close together to complete the bending of the electrode tab, the first pressing component drives the second pressing component away from the second pressing component. At this time, the first spring can press the first pressing component towards the second pressing component to keep the first pressing component pressed and fixed with the second pressing component to secure the electrode tab. Thus, when the feeding module puts the insulating cap into the first electrode tab, the first pressing component can rely on the elastic force of the first spring to keep the electrode tab pressed and fixed, avoiding the electrode tab from being displaced and damaged by the insulating cap.

[0020] According to some embodiments of the present invention, the first pressing assembly further includes a first slide block, which is used to drive the first pressing member and the second pressing member to move closer to and away from the second pressing assembly. The first slide block is provided with a first guide rail, and the first pressing member slides along the first guide rail.

[0021] The advantage of this invention is that by setting a first slide block, which is used to drive the first pressing component and the second pressing component to move closer to and away from the second pressing component, and by setting a first guide rail on the first slide block, the first pressing component slides along the first guide rail, thereby making the sliding of the first pressing component on the first slide block more stable.

[0022] According to some embodiments of the present invention, the first pressing assembly further includes a first slide block and a first cylinder. The first slide block is used to drive the first pressing member and the second pressing member to move closer to and away from the second pressing assembly. The second pressing member is slidably connected to the first slide block. The first cylinder is used to drive the second pressing member to move closer to and away from the second pressing assembly.

[0023] The advantages of this invention are: by setting a first slide and a first cylinder, the first slide is used to drive the first and second pressing components to move closer to and away from the second pressing assembly. The second pressing component is slidably connected to the first slide, and the first cylinder is used to drive the second pressing component to move closer to and away from the second pressing assembly. It can be understood that when the second pressing assembly, the first pressing component, and the second pressing component close together to complete the bending of the electrode tab, the first cylinder first drives the second pressing component away from the second pressing assembly, so that the second pressing component can separate from the second pressing assembly first. At this time, the first pressing component can maintain a tight and fixed electrode tab with the second pressing assembly, thereby enabling the second pressing component and the first pressing component to separate from the second pressing assembly in sequence.

[0024] According to some embodiments of the present invention, a second guide rail is provided on the first slide block, and the second pressing member slides along the second guide rail.

[0025] The advantage of this invention is that by providing a second guide rail on the first slide block, the second pressing component slides along the second guide rail, thereby making the sliding of the second pressing component on the first slide block more stable.

[0026] According to some embodiments of the present invention, the first pressing member includes a first step portion and a second step portion, the first step portion and the second step portion having a height difference, the third pressing member and the fourth pressing member having a height difference, and the first step portion and the second step portion respectively engaging with the third pressing member and the fourth pressing member to bend the electrode lug.

[0027] The advantages of this invention are: by providing a first step and a second step in the first pressing component, with a height difference between the first step and the second step, and a height difference between the third pressing component and the fourth pressing component, the first step and the second step respectively engage with the third pressing component and the fourth pressing component to bend the electrode ear. Thus, when the first pressing component engages with the second pressing component, the third pressing component supports the electrode ear, and then the second step can engage with the fourth pressing component to bend the electrode ear.

[0028] According to some embodiments of the present invention, the support height of the fourth pressing component is less than the support height of the third pressing component, the second pressing component and the fourth pressing component are joined together, and the feeding module is located on the side of the fourth pressing component facing away from the third pressing component.

[0029] The advantage of this invention is that by making the support height of the fourth pressing component less than that of the third pressing component, the second pressing component and the fourth pressing component are closed and fitted together, and the feeding module is located on the side of the fourth pressing component away from the third pressing component. Thus, when the second pressing component and the fourth pressing component are separated, the feeding module can put the insulating cap into the electrode ear from the side of the fourth pressing component away from the third pressing component, avoiding the third pressing component from obstructing the insulating cap.

[0030] According to some embodiments of the present invention, the first pressing component includes a first slide block, the second pressing component includes a second slide block, and a third guide rail is also included. The first slide block and the second slide block slide along the third guide rail to make the first pressing component and the second pressing component move closer to each other and further away from each other.

[0031] The advantage of this invention is that by having the first pressing component include a first slide, the second pressing component include a second slide, and a third guide rail, the first slide and the second slide slide along the third guide rail to make the first pressing component and the second pressing component move closer to each other and further away from each other, thereby making the closing or separating movements of the first pressing component and the second pressing component smoother.

[0043] The electrode insulating cap assembly mechanism according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0044] This utility model aims to provide an embodiment of the electrode insulating cap assembly mechanism.

[0045] Reference Figure 1and Figure 2 In this embodiment, the electrode insulating cap assembly mechanism mainly includes a first pressing component 100, a second pressing component 130, and a feeding module 140.

[0046] The first clamping assembly 100 includes a first pressing element 110 and a second pressing element 120.

[0047] The second clamping assembly 130 includes a third clamping member 220 and a fourth clamping member 230, which are respectively joined with the first clamping member 110 and the second clamping member 120 to bend the electrode tab.

[0048] For the feeding module 140, the feeding module 140 is used to fit the insulating cap into the bent electrode tab.

[0049] Among them, the second pressing component 120 and the fourth pressing component 230, and the first pressing component 110 and the third pressing component 220 are separated in sequence. When the feeding module 140 puts the insulating cap into the first electrode ear, the first pressing component 110 and the third pressing component 220 keep pressing and fixing the electrode ear.

[0050] In this embodiment, a first pressing element 110 and a second pressing element 120 are provided in the first pressing assembly 100, and a third pressing element 220 and a fourth pressing element 230 are provided in the second pressing assembly 130. After the third pressing element 220 and the fourth pressing element 230 are respectively closed with the first pressing element 110 and the second pressing element 120 to complete the bending of the electrode tab, the second pressing element 120 and the fourth pressing element 230, and the first pressing element 110 and the third pressing element 220, separate sequentially. It can be understood that after the first pressing assembly 100 and the second pressing assembly 130 complete the bending of the electrode tab, the second pressing element 120 and the fourth pressing element 230 separate first. At this time, the second pressing element 120 and the fourth pressing element 230 can move away from each other. The electrode tab is positioned to avoid the insulating cap. Then, the feeding module 140 inserts the insulating cap into the first section of the electrode tab, which is the part of the electrode tab that is loosened by the second pressing component 120 and the fourth pressing component 230. At this time, the first pressing component 110 and the third pressing component 220 still keep the electrode tab pressed and fixed, so that the bent electrode tab will not shift in position when the insulating cap is inserted into the first section. Then, after the insulating cap is inserted into the first section of the electrode tab, the first pressing component 110 and the third pressing component 220 separate, and the feeding module 140 continues to completely insert the insulating cap into the electrode tab. This prevents the bent electrode tab from shifting in position, improves the assembly accuracy of the electrode tab and the insulating cap, and avoids the electrode tab of the battery cell being deformed due to squeezing between the electrode tab and the insulating cap during the assembly of the insulating cap.

[0051] Reference Figure 1 , Figure 2 and Figure 3In some specific embodiments, the first pressing member 110 and the second pressing member 120 can move relative to each other in the direction of approaching and moving away from the second pressing assembly 130. The second pressing member 120 moves relative to the first pressing member 110 away from the second pressing assembly 130 to disengage from the electrode tab. Thus, the second pressing member 120 and the first pressing member 110 can disengage from the electrode tab in sequence, avoiding the first pressing member 110 and the second pressing member 120 from disengaging from the electrode tab at the same time and losing the fixation of the electrode tab position.

[0052] In some specific embodiments, the first pressing component 100 and the second pressing component 130 are arranged vertically. When the first pressing component 100 rises, it causes the second pressing component 120 and the first pressing component 110 to move relative to each other away from the second pressing component 130 to disengage from the electrode tab. This allows the first pressing component 110 to keep the electrode tab pressed and fixed when the feeding module puts the insulating cap into the first electrode tab, thus preventing the electrode tab from shifting position and being squeezed and damaged by the insulating cap.

[0053] In other embodiments, the first clamping assembly 100 may include a first spring 150 for pressing the first pressing member 110 toward the second clamping assembly 130. When the first clamping assembly 100 moves away from the second clamping assembly 130, the first spring 150 presses the first pressing member 110 to keep it pressed and fixed with the second clamping assembly 130.

[0054] Understandably, after the second clamping assembly 130, the first clamping member 110, and the second clamping member 120 close together to complete the bending of the electrode tab, the first clamping assembly 100 drives the second clamping member 120 away from the second clamping assembly 130. At this time, the first spring 150 can press the first clamping member 110 towards the second clamping assembly 130 so that the first clamping member 110 remains pressed and fixed with the second clamping assembly 130. Thus, the first clamping member 110 can rely on the elastic force of the first spring 150 to keep the electrode tab pressed and fixed when the feeding module puts the insulating cap into the first electrode tab, avoiding the electrode tab from shifting position and causing the electrode tab to be squeezed and damaged by the insulating cap.

[0055] Furthermore, the first pressing assembly 100 also includes a first slide 160, which is used to drive the first pressing member 110 and the second pressing member 120 to move closer to and away from the second pressing assembly 130. The first slide 160 is provided with a first guide rail 170, and the first pressing member 110 slides along the first guide rail 170, thereby making the sliding of the first pressing member 110 on the first slide 160 more stable.

[0056] Furthermore, two first guide rails 170 are provided, thereby making the guidance of the first pressing component 110 more stable by the cooperation of the two first guide rails 170.

[0057] In some specific embodiments, a limiting pin is also provided on the first slide block 160. The limiting pin is used to limit the maximum sliding position of the first pressing member 110 on the first slide block 160 in the direction close to the second pressing assembly 130, thereby preventing the first pressing member 110 from being dislodged from the first slide block 160 by its own weight or by the elastic force of the first spring 150.

[0058] In some other embodiments, the first pressing assembly 100 further includes a first slide 160 and a first cylinder 180. The first slide 160 is used to drive the first pressing member 110 and the second pressing member 120 to move closer to and away from the second pressing assembly 130. The second pressing member 120 is slidably connected to the first slide 160. The first cylinder 180 is used to drive the second pressing member 120 to move closer to and away from the second pressing assembly 130.

[0059] Understandably, after the second pressing component 130, the first pressing component 110, and the second pressing component 120 close together to complete the bending of the electrode tab, the first cylinder 180 first drives the second pressing component 120 away from the second pressing component 130, so that the second pressing component 120 can separate from the second pressing component 130 first. At this time, the first pressing component 110 can keep pressing and fixing the electrode tab with the second pressing component 130, thereby enabling the second pressing component 120 and the first pressing component 110 to separate from the second pressing component 130 in sequence.

[0060] Furthermore, a second guide rail 190 is provided on the first slide block 160, and the second pressing member 120 slides along the second guide rail 190, thereby making the sliding of the second pressing member 120 on the first slide block 160 more stable.

[0061] Furthermore, two second guide rails 190 are provided, thereby making the two second guide rails 190 cooperate to guide the second pressing component 120 more smoothly.

[0062] In some specific embodiments, the first pressing member 110 includes a first step portion 200 and a second step portion 210, with a height difference between the first step portion 200 and the second step portion 210. The third pressing member 220 and the fourth pressing member 230 also have a height difference. The first step portion 200 and the second step portion 210 respectively engage with the third pressing member 220 and the fourth pressing member 230 to bend the electrode tab. Thus, when the first pressing member 110 engages with the second pressing assembly 130, the third pressing member 220 supports the electrode tab, and then the second step portion 210 can engage with the fourth pressing member 230 to bend the electrode tab.

[0063] Reference Figure 1 , Figure 2 and Figure 4In some specific embodiments, the support height of the fourth pressing member 230 is less than the support height of the third pressing member 220. The second pressing member 120 and the fourth pressing member 230 are closed together. The feeding module 140 is located on the side of the fourth pressing member 230 away from the third pressing member 220. Thus, when the second pressing member 120 and the fourth pressing member 230 are separated, the feeding module 140 can put the insulating cap into the electrode ear from the side of the fourth pressing member 230 away from the third pressing member 220, so as to avoid the third pressing member 220 obstructing the insulating cap.

[0064] In some specific embodiments, the second pressing assembly 130 further includes a second slide 240, and the fourth pressing element 230 is slidably connected to the second slide 240. A second cylinder is provided on the second slide 240. The second cylinder is used to drive the fourth pressing element 230 to approach and move away from the first pressing assembly 100, thereby facilitating the second cylinder to drive the fourth pressing element 230 to separate from the second pressing element 120 first.

[0065] In some specific embodiments, the first pressing assembly 100 includes a first slide 160, the second pressing assembly 130 includes a second slide 240, and a third guide rail 250 is also included. The first slide 160 and the second slide 240 slide along the third guide rail 250 to make the first pressing assembly 100 and the second pressing assembly 130 move closer and further away from each other, thereby making the closing or separating movements of the first pressing assembly 100 and the second pressing assembly 130 smoother.

[0066] Furthermore, two third guide rails 250 are provided, thereby making the guidance of the first slide 160 and / or the second slide 240 more stable by the cooperation of the two third guide rails 250.

[0067] In some specific embodiments, a first motor or a third cylinder is also included, which is used to drive the first slide block 160 to slide.

[0068] In some specific embodiments, a second motor or a fourth cylinder is also included, which is used to drive the second slide 240 to slide.
