[0033] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0034] The utility model relates to a kind of tool for moving pole group, to facilitate the moving of pole group 6, and can solve the problem of pole group moving tool in prior art easily damaging tab 601.

[0035] Overall constitution, the tool for moving pole group includes base 1 and clamping unit arranged on base 1. Among them, clamping unit includes clamping part for clamping two opposite sides of pole group 6, and pressing plate 3 is slidably arranged on base 1, and pressing plate 3 is used to abut with the top surface of pole group 6, and the avoiding portion for avoiding tab 601 is arranged on pressing plate 3.

[0036] The tool for moving pole group described in the embodiment, by the clamping part in clamping unit clamping pole group 6, and pressing plate 3 abuts with the top surface of pole group 6, facilitate to improve the clamping effect of pole group 6, and have good clamping stability, to facilitate to ensure the stability of pole group 6 in moving, and by setting the avoiding portion for avoiding tab 601 on pressing plate 3, facilitate to avoid that pressing plate 3 damages tab 601, prevent tab 601 from being damaged in moving process, to facilitate to improve the quality and reliability of pole group 6.

[0037] Based on the overall introduction as above, an exemplary structure of the tool for moving pole group described in the embodiment is shown in Figure 1 Base 1 provides stable support basis for the whole tool, to facilitate to ensure that the tool does not shake or tilt in moving process. Base 1 is preferably horizontally arranged plate, its structure is simple, and it is conducive to the arrangement of clamping unit. The clamping part in the embodiment clamps pole group 6 from both sides, while cooperating with pressing plate 3 from top abutment, can provide stable clamping force to pole group 6, to facilitate to ensure that pole group 6 does not loosen or fall in moving process. In specific implementation, the spacing of clamping part and the height of pressing plate 3 can be adjusted to adapt to pole group 6 of different sizes, improve the versatility of the tool, and the tool does not need to be replaced frequently, thereby facilitating to reduce production cost.

[0038] The pressing plate 3 in the embodiment is slidably arranged on the base 1, so that by sliding the pressing plate 3, the pressing plate 3 is facilitated to be closely abutted with the top surface of the pole group 6, the pole group 6 is effectively prevented from being damaged due to shaking or collision during the transferring process, and the safety of the pole group 6 during the transferring process is improved. The avoiding part on the pressing plate 3 can effectively avoid the pole lug 601, and avoid damaging the pole lug 601 during clamping.

[0039] As a preferred embodiment, the avoiding part comprises avoiding grooves 301 arranged on the bottom surface of the pressing plate 3, and the avoiding grooves 301 are arranged one-to-one with the pole lug 601. Here, the avoiding grooves 301 provide a safe space for the pole lug 601, and ensure that the pole lug 601 is not affected by external forces such as collision and extrusion, thereby preventing the pressing plate 3 from damaging the pole lug 601. The avoiding grooves 301 are arranged one-to-one with the pole lug 601, which ensures that each pole lug 601 can accurately enter the corresponding avoiding groove 301, thereby maximizing the protection effect on the pole lug 601. Of course, in addition to the avoiding grooves 301, the avoiding part can also use avoiding holes, as long as it meets the use requirements of avoiding the pole lug 601.

[0040] In some embodiments, the pole group 6 has pole lugs 601 at both ends, and at this time, the avoiding part is arranged at both ends of the pressing plate 3. By arranging the avoiding part at both ends of the pressing plate 3, the pole group 6 with the pole lugs 601 arranged at both ends can be transferred. Figure 1 In some embodiments, the pole group 6 has pole lugs 601 at both ends, and at this time, the avoiding part is arranged at both ends of the pressing plate 3. By arranging the avoiding part at both ends of the pressing plate 3, the pole group 6 with the pole lugs 601 arranged at both ends can be transferred.

[0041] As a preferred embodiment, as shown in Figure 2 The length L of the avoiding groove 301 in the width direction of the pole group 6 is between 280mm-320mm. Here, the length range of the avoiding groove 301 in the width direction of the pole group 6 is selected according to the common size of the pole lug 601. In the production of lithium ion batteries, the size of the pole lug 601 usually has a certain standard range, and the avoiding groove 301 with a length L of 280mm-320mm can cover the width direction size of most common pole lug 601, thereby ensuring the universality of the tooling.

[0042] In addition, the length of the avoiding groove 301 cannot be too long, otherwise it will affect the strength and stability of the pressing plate 3. When the length L of the avoiding groove 301 in the width direction of the pole group 6 is between 280mm-320mm, the pressing plate 3 can withstand the pressure of the pole group 6 without deformation or damage due to the length of the avoiding groove 301 being too long. In specific implementation, the length L here can be 280mm, 290mm, 300mm, 310mm or 320mm, etc.

[0043] As a preferred embodiment, still referring to Figure 2As shown in FIG. 1, the depth D of the avoiding groove 301 is between 45mm and 55mm. The setting of the depth range of the avoiding groove 301 can ensure that the tab 601 is completely placed in the avoiding groove 301, avoiding the tab 601 being damaged by scratching the bottom surface of the pressing plate 3, thereby ensuring the safety and stability of the pole group 6 during the transfer process. In a lithium ion battery, the tab 601 has a certain thickness, and the avoiding groove 301 with a depth D between 45mm and 55mm can ensure that the tab 601 is completely placed in the avoiding groove 301, which is beneficial to avoid the tab 601 being damaged by protruding from the bottom surface of the pressing plate 3, thereby ensuring the safety and stability of the pole group 6 during the transfer process.

[0044] If the depth D of the avoiding groove 301 exceeds 55mm, the overall strength of the pressing plate 3 will be weakened, causing the pressing plate 3 to be easily deformed when applying pressure to the pole group 6, affecting the fixing effect of the pole group 6. When the depth D of the avoiding groove 301 is less than 45mm, the tab 601 cannot be effectively accommodated, thereby failing to avoid the tab 601. In specific implementation, the depth D may be, for example, 45mm, 48mm, 50mm, 52mm, or 55mm, etc.

[0045] In order to improve the use effect of the clamping part, as shown in FIG. 1, the clamping part in the embodiment includes two clamping jaws 2 slidingly arranged on the base 1, and a first driving part for driving each clamping jaw 2 to slide, and the two clamping jaws 2 can be close to each other to clamp on both sides in the width direction of the pole group 6. Figure 1 As shown in FIG. 1, the clamping part in the embodiment includes two clamping jaws 2 slidingly arranged on the base 1, and a first driving part for driving each clamping jaw 2 to slide, and the two clamping jaws 2 can be close to each other to clamp on both sides in the width direction of the pole group 6.

[0046] In specific implementation, the material of the clamping jaw 2 is generally selected to have certain strength and wear resistance, such as metal or high-strength plastic, to ensure reliability during long-term use. When the pole group 6 needs to be clamped, the first driving part is started to drive the two clamping jaws 2 to slide towards each other, and the clamping jaws 2 gradually approach both sides in the width direction of the pole group 6 during the sliding process, until the pole group 6 is tightly clamped.

[0047] During the clamping process, the friction and clamping force between the clamping jaw 2 and the pole group 6 jointly act to ensure that the pole group 6 does not move laterally during the transfer process. At the same time, the position and clamping force of the clamping jaw 2 can be adjusted according to the size and weight of the pole group 6 to achieve the best clamping effect. When the pole group 6 needs to be released, the first driving part is reversely operated to drive the clamping jaw 2 to slide away from the pole group 6, thereby releasing the pole group 6.

[0048] As a feasible implementation, still referring to FIG. 1, Figure 1As shown in the figure, each of the clamping jaws 2 is in "L" shape, and has a vertical portion 201 and a horizontal portion 202 arranged in connection. The vertical portion 201 is used to abut against the side wall of the pole group 6, and the horizontal portion 202 is used to support the bottom surface of the pole group 6. Here, the clamping jaw 2 is in "L" shape, and can fix the pole group 6 from the side and the bottom, and the horizontal portion 202 cooperates with the pressing plate 3 to further improve the clamping stability of the clamping unit to the pole group 6.

[0049] In detail, the length and width of the vertical portion 201 are usually designed according to the size of the pole group 6 to ensure that it can closely fit the side wall of the pole group 6 and provide stable lateral support. The surface of the vertical portion 201 can be appropriately treated, such as adding a non-slip coating or a rubber pad, to increase the friction between the vertical portion 201 and the side wall of the pole group 6 and prevent the pole group 6 from slipping during the moving process. The horizontal portion 202 is used to support the bottom surface of the pole group 6. The thickness and strength of the horizontal portion 202 need to be able to withstand the weight of the pole group 6, while also ensuring that it will not be deformed or damaged during the moving process.

[0050] When the clamping jaw 2 clamps the pole group 6, the vertical portion 201 closely abuts against the side wall of the pole group 6 to provide lateral support. The horizontal portion 202 supports the bottom surface of the pole group 6 to prevent the pole group 6 from falling downward. During the moving process, the "L" shape of the clamping jaw 2 can effectively fix the pole group 6 on the tooling to ensure the stability of the position of the pole group 6.

[0051] In this embodiment, the top end of the vertical portion 201 is slidably arranged on the base 1 along the width direction of the pole group 6. To improve the stability of the clamping jaw 2 during sliding, a sliding groove for guiding the sliding of the clamping jaw 2 can be arranged on the base 1. The first driving part in this embodiment can adopt a pneumatic cylinder, and the power output end of the pneumatic cylinder is connected to the top end of the vertical portion 201 to drive the two clamping jaws 2 to move closer to or away from each other.

[0052] In addition, the tooling for moving the pole group in this embodiment also includes a lifting part 5 arranged on the base 1, and the lifting end of the lifting part 5 is connected to the pressing plate 3 to drive the pressing plate 3 to slide up and down relative to the base 1. Here, the arrangement of the lifting part 5 can realize accurate control of the height of the pressing plate 3, so that it can be adjusted according to the thickness and size of different pole groups 6 to ensure that the abutting force of the pressing plate 3 against the top surface of the pole group 6 is moderate, neither causing excessive extrusion of the pole group 6 nor damaging the pole group 6, and also providing sufficient fixing force to ensure the stability of the pole group 6 during the moving process.

[0053] In detail, the length and width of the vertical portion 201 are usually designed according to the size of the pole group 6 to ensure that it can closely fit the side wall of the pole group 6 and provide stable lateral support. The surface of the vertical portion 201 can be appropriately treated, such as adding a non-slip coating or a rubber pad, to increase the friction between the vertical portion 201 and the side wall of the pole group 6 and prevent the pole group 6 from slipping during the moving process. The horizontal portion 202 is used to support the bottom surface of the pole group 6. The thickness and strength of the horizontal portion 202 need to be able to withstand the weight of the pole group 6, while also ensuring that it will not be deformed or damaged during the moving process. Figure 1As shown in the figure, the lifting end of the lifting part 5 is provided with a plurality of connecting rods 502, and the lifting part 5 is connected with the pressing plate 3 through the plurality of connecting rods 502. By connecting the lifting part 5 with the pressing plate 3 through the plurality of connecting rods 502, the tilting or shaking of the pressing plate 3 during lifting can be effectively prevented, the pole group 6 can be ensured to always remain in the correct position, and the precision and reliability of the transfer are improved. The lifting part 5 here can also use a pneumatic cylinder, and the power output end of the pneumatic cylinder is provided with a connecting plate 501, and a plurality of connecting rods 502 are arranged between the connecting plate 501 and the pressing plate 3. Of course, the arrangement form of the connecting rods 502 can also be adaptively adjusted according to the use requirements.

[0054] In order to further improve the use flexibility of the pole group transfer tool, the pole group transfer tool of the embodiment further comprises a second driving part 4, the power output end of the second driving part 4 is connected with the base 1, and the second driving part 4 is used to drive the base 1 to lift and / or rotate. By driving the base 1 to lift and / or rotate through the second driving part 4, the pole group transfer tool can quickly and accurately transfer the pole to the required position, thereby facilitating the reduction of the time and labor intensity of manual adjustment.

[0055] When the second driving part 4 performs the lifting action, the second driving part 4 will drive the base 1 to move up and down, which can adjust the height of the clamping unit, thereby facilitating the clamping and transfer of the pole group 6. As a preferred embodiment, the second driving part 4 can use a rotary pneumatic cylinder, which can drive the base 1 to rotate and lift, thereby having better transfer flexibility.

[0056] In use, the pole group transfer tool in the embodiment first drives the base 1 to move downward through the second driving part 4, until the clamping jaws move to both sides of the pole group 6, at this time the pressing plate 3 is located above the pole group 6 and is arranged in a spaced manner with the pole group 6. Then the first driving part drives the two clamping jaws 2 to move close to each other, so that the vertical part 201 clamps both sides of the pole group 6, and the horizontal part 202 supports the bottom surface of the pole group 6.

[0057] Then the lifting part 5 drives the pressing plate 3 to move downward, so that the pressing plate 3 abuts against the top surface of the pole group 6, thereby completing the clamping of the pole group 6. Finally, the second driving part 4 moves upward and can drive the base 1 to rotate, thereby facilitating the adjustment of the angle of the pole group 6, thereby meeting the transfer requirements of the pole group 6, and the entire transfer process has good stability.

[0058] The pole group transfer tool described in the embodiment not only has a simple structure, is easy to arrange and implement, and has high transfer stability, but also has the avoiding part arranged on the pressing plate 3 to avoid the pole lug 601, which is beneficial to prevent the pressing plate 3 from damaging the pole lug 601, thereby improving the use performance of the pole lug 601.

[0059] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
