Description

Technical Field

[0001] The utility model relates to the technical field of battery steel strips, and in particular to a heat shrink positioning device for an insulation layer of a battery steel strip. Background Art

[0002] When the lithium battery pack is working, the lithium battery cells in the lithium battery pack need to be tied and fixed by steel belts to arrange the lithium battery cells neatly and prevent the shells of the lithium battery cells from shaking during operation, thereby protecting the lithium battery pack. In the existing steel belt production process, the straight steel belt needs to be bent and welded to form a frame, so that the lithium battery pack can be easily inserted into the frame for positioning.

[0003] During the production and processing of steel strips, the steel strips need to be led out from the reel, cut into a fixed length, and then bent into a U shape. An insulating sleeve is put on the long side of the U-shaped steel strip, and then the two ends of the U-shaped steel strip are bent and welded to form a rectangular frame. The steel strip is then placed in a heat shrink molding device to allow the insulating sleeve to shrink and fit onto the surface of the steel strip. During this process, the position of the insulating sleeve on the steel strip needs to be limited. Since different types of battery steel strips have different widths and arc groove curvatures, there is no heat insulation layer shrinkage positioning device that can be applied to different types of battery steel strips in the prior art.

[0027] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0028] Please refer to Figures 1 to 4 , a heat shrink positioning device for an insulation layer of a battery steel strip, comprising:

[0029] Base 1;

[0030] The limit block 2 is movably connected to the base 1 along the X direction, and a plurality of arc grooves 21 with different curvatures are provided on the limit block 2. The opening of the arc groove 21 faces the Z direction, one end of the arc groove 21 faces the Y direction, and the other end of the arc groove 21 faces the X direction. The central angle of the arc groove 21 is less than 90 degrees;

[0031] The positioning block 3 is movably connected to the base 1 along the X direction, and a linear groove 31 along the Y direction is provided on the positioning block 3. The positioning block 3 is located at one side of the limit block 2 in the Y direction;

[0032] The positioning block 3 is located on the Y-direction side of the limiting block 2;

[0033] A first moving mechanism 4, the first moving mechanism 4 is used to drive the limit block 2 to move;

[0034] A second moving mechanism 5, the second moving mechanism 5 is used to drive the positioning block 3 to move;

[0035] In a certain state of the limiting block 2 , one end of the arc-shaped groove 21 with different curvatures in the Y direction is aligned with the linear groove 31 .

[0036] In the above implementation mode, it should be noted that, since the central angle of the arc groove 21 is less than 90 degrees, the arc segment of the arc groove 21 on the side facing the Y direction is a straight segment. By setting the positioning block 3, the insulating layer of the U-shaped battery steel strip can be more stably bonded to the surface of the U-shaped battery steel strip. The specific method is as follows: put the thermal insulation sleeve on both sides of the U-shaped battery steel strip, and the corner of the U-shaped battery steel strip with the thermal insulation sleeve is bonded to the arc groove 21 on the limit block 2, and then use the straight groove 31 of the positioning block 3 to fit the straight section in the arc groove 21 of the U-shaped battery steel strip. Cooperating with its limiting function, the U-shaped battery steel strip is limited on the base 1, and then the base is stood up so that the Y side of the base is suspended upwards, and it is sent into the heat shrink device, so that the heat shrink insulation sleeve is attached to the surface of the U-shaped battery steel strip. Since the limiting block 2 is provided with arc grooves 21 with different curvatures, battery steel strips suitable for different turning angles can be used. Since the limiting block 2 can move along the X direction or the X reverse direction, the width of the battery steel strip can be controlled. Therefore, compared with the prior art, it can be suitable for battery steel strips with different widths and different turning curvatures.

[0037] As an optional embodiment, the first moving mechanism 4 includes a first screw guide rail assembly 41 and a first slider 42. The first screw guide rail assembly 41 is connected to the base 1. The axial direction of the first screw guide rail assembly 41 is the X direction. The first slider 42 is slidably connected to the first screw guide rail assembly 41, and the limit block 2 is connected to the slider.

[0038] In the above embodiment, the first sliding block 42 is slidably connected to the first screw guide rail assembly 41, thereby driving the limit block 2 to stably move along the X direction or the X reverse direction.

[0039] As an optional embodiment, the second moving mechanism 5 includes a second screw guide rail assembly 51 and a second slider 52. The second screw guide rail assembly 51 is connected to the base 1. The second screw guide rail assembly 51 is located on the Y-direction side of the first screw guide rail assembly 41. The axial direction of the second screw guide rail assembly 51 is the X-direction. The second slider 52 is slidably connected to the second screw guide rail assembly 51, and the positioning block 3 is connected to the second slider.

[0040] In the above embodiment, the second slider 52 is slidably connected to the second screw guide rail assembly 51, so that the positioning block 3 can be moved in the X direction or the X reverse direction, thereby cooperating with the movement of the limit block 2, so that the limit block 2 is in a certain state, and the straight groove 31 of the positioning block 3 is aligned with the arc groove 21Y of the limit block 2 toward one end.

[0041] As an optional implementation, a slot 421 is provided on the first sliding block 42 , and a limiting column 22 matching the slot 421 is provided on the limiting block 2 .

[0042] In the above implementation manner, different limit blocks 2 can be replaced by plugging and matching the limit column 22 with the slot 421, so as to be suitable for battery steel strips with more different arc angles.

[0043] As an optional implementation, the limiting block 2 is provided with four arc-shaped grooves 21 with different curvatures.

[0044] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
