DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-8 In an embodiment of the utility model, a lithium battery diaphragm roll core adhesive strip device includes a main frame and a fixing frame arranged on the surface of the main frame. The main frame is composed of two symmetrically arranged arc-shaped brackets 1. A plurality of square grooves 2 are provided on the two arc-shaped brackets 1. The two arc-shaped brackets 1 are connected by fasteners 5. A limit block 9 for limiting the position of the roll core is fixedly installed at the end of the arc-shaped bracket 1.

[0025] Specifically, the two symmetrically arranged arc-shaped brackets 1 are adjusted to have a spacing therebetween under the action of the fasteners 5, so as to facilitate the subsequent placement of the roll core between the two arc-shaped brackets 1. Secondly, the existence of the limit block 9 can limit one end of the roll core to prevent the phenomenon that one end of the roll core is too long when the roll core is inserted between the two arc-shaped brackets 1, thereby reducing the time for adjusting the roll core. At the same time, the design of the multiple square grooves 2 is adapted to the film to be pasted, so as to standardize the action of pasting the adhesive strip, reduce human errors, and reduce the time for pasting the adhesive strip on the roll core.

[0026] See also Figure 3 In the first embodiment, in this embodiment, preferably, the fastener 5 includes two second clamping blocks 56 arranged on the two arc-shaped brackets 1, and the two second clamping blocks 56 are connected by a threaded rod 57 whose ends pass through the two second clamping blocks 56, and the ends of the threaded rod 57 passing through the two second clamping blocks 56 are both threadedly connected with threaded sleeves 58.

[0027] When in use, the distance between the two arc-shaped brackets 1 is adjusted by rotating the threaded sleeve 58 on the threaded rod 57 clockwise or counterclockwise, so as to achieve the effect of quickly replacing the winding core, and the actual use effect is obvious.

[0028] See also Figure 4-7In the second embodiment, in this embodiment, preferably, the fastener 5 includes two first clamping blocks 51 arranged on the two arc-shaped brackets 1, and the two first clamping blocks 51 are connected by a movable rod 52 whose ends pass through the two first clamping blocks. The outer peripheral surface of the movable rod 52 is sleeved with a spring 53 whose ends are respectively connected to the surfaces of the two first clamping blocks 51, and the ends of the movable rod 52 passing through the two first clamping blocks 51 are both installed with connecting rods 54, and buckles 55 are both installed on the two connecting rods 54.

[0029] Specifically, the two arc-shaped brackets 1 are fixedly installed with first clamping blocks 51 near the adjacent fitting positions, and the two first clamping blocks 51 are both provided with through holes, and the two through holes are concentrically arranged. The movable rod 52 passes through the two through holes, and grooves are provided at the non-adjacent ends of the two first clamping blocks 51, and a connecting rod 54 is fixedly installed in the groove, and the connecting rod 54 is connected to the buckle 55 by interference fit, and the groove setting can prevent the buckle 55 from being affected when moving.

[0030] When in use, by adjusting the buckle 55 on the connecting rod 54 and rotating the buckle 55, the two arc-shaped brackets 1 can be merged when the buckle 55 squeezes the first clamping block 51, and rotating the buckle 55, when the buckle 55 is not in contact with the first clamping block 51, the two arc-shaped brackets 1 are separated under the action of the spring 53, so that the winding cores in the two arc-shaped brackets 1 can be easily taken out.

[0031] See also Figure 1-4 In one embodiment, in this embodiment, preferably, an annular groove 3 is provided at positions near both ends of the outer circumference of the arc-shaped bracket 1, and a rotating part is installed on the arc-shaped bracket 1 to assist its axial rotation.

[0032] See also Figure 4 In one embodiment, in this embodiment, preferably, the rotating part is specifically an auxiliary strip 4 installed on the surface of the arc-shaped bracket 1, and a rubber strip is arranged in a ring shape on the outer peripheral surface of the auxiliary strip 4.

[0033] Specifically, the staff can rotate the rubber strip on the auxiliary strip 4 to increase the friction between the rubber strip and the hand, so that the staff can drive the arc bracket to rotate 1360 degrees to complete the sticking of the rubber strip.

[0034] See also Figure 1 In one embodiment, in this embodiment, preferably, the rotating part is specifically a handle 10 installed on the surface of the arc-shaped bracket 1.

[0035] By rotating the handle 10 , the staff can drive the arc-shaped bracket to rotate 1360° to complete the adhesive strip pasting.

[0036] See also Figure 1 and Figure 4In one embodiment, in this embodiment, preferably, the fixing frame includes a vertically arranged support rod 6, and the two ends of the support rod 6 are respectively installed with a base 7 and a limiting semi-ring 8, and the limiting semi-ring 8 is designed to be arc-shaped and its inner diameter is adapted to the outer diameter of the annular groove 3.

[0037] Specifically, the base 7 is fixed to the ground, and the support rod 6 connects the base 7 and the limiting semi-ring 8, and under the action of the limiting semi-ring 8 and the annular groove 3, limits the rotation direction of the main frame.

[0038] The working principle and use process of the utility model are as follows: first, the staff adjusts the distance between the two arc-shaped brackets 1 through the fastener 5. When the distance between the two arc-shaped brackets 1 is too large, the core can be better placed between the two. Then, the two arc-shaped brackets 1 are closed through the fastener 5 to achieve the effect of fixing the core. At the same time, the design of the limit block 9 can preliminarily limit the core in the arc-shaped bracket 1. Then, the staff directly sticks the rubber strip on the surface of the core through the square groove 2, saving some time for sticking the rubber strip. Secondly, under the action of the limiting semi-ring 8 and the annular groove 3, the rotation direction of the main frame is limited, which is convenient for sticking the rubber strip around the core. Finally, the fastener 5 is adjusted to open the two arc-shaped brackets 1, and the core after sticking the rubber strip can be directly taken out.

[0039] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0040] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
