Description

Technical Field

[0001] The utility model relates to the technical field of lamination machines, in particular to a rotatable glue brush. Background Art

[0002] The stacking machine consists of a diaphragm unwinding and feeding device, a multi-station composite material retrieving and paper swinging robot, a modular lifting workbench device, a modular paper pressing mechanism, a flat-plate special vacuum adsorption device, and an electrical control and operation panel (including a touch screen). It can automatically stack battery cells and is one of the key equipment for the automated production of prismatic lithium batteries.

[0003] A bare cell refers to a single electrochemical cell containing positive and negative electrodes. After the bare cell is rolled up, it needs to be glued and then a brush is used to stick the tail diaphragm to the side of the bare cell to form a closed state. This prevents the bare cell from having electrode misalignment and diaphragm folding during operation and subsequent formation and degassing processes.

[0004] In the prior art, a brush is often fixed on a bracket for use in applying glue. For example, Chinese patent announcement No. "CN200960503Y" discloses a glue applicator, which includes a roller brush, which is movably mounted on the upper end of a shell, and a cavity for storing glue is formed between the roller brush and the shell; corresponding holes are processed on the two side surfaces of the shell, and a roller brush shaft passes through the roller brush to fix the roller brush between the two holes of the shell and can rotate around the roller brush shaft. The shell with the roller brush is divided into an inlet and an outlet, and a protruding scraper is processed at the outlet to closely fit with the roller brush; side panels are provided at both ends of the roller brush and are fixed by the roller brush shaft; a gear is provided on the roller brush; a thread is processed on the lower end of the shell and is threadedly connected to the glue bottle; compared with the prior art, the utility model has the characteristics of continuous supply of glue and fast and uniform gluing.

[0005] In actual operation, it is not easy to disassemble the roller brush and the shell. After a long period of use, the roller brush will accumulate and solidify because it is not convenient to replace and clean it, which can easily cause damage to the battery cell. At the same time, the deformation of the brush may also lead to poor glue application, affecting the normal use of subsequent glue dispensing. Utility Model Content

[0006] The purpose of the utility model is to solve the disadvantage in the prior art that it is inconvenient to replace and clean the glue between the roller brush and the shell, and to propose a rotatable glue brush.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A rotatable glue brush is designed, comprising a bracket and a brush arranged in the bracket, wherein the bracket comprises a supporting portion and a connecting portion, wherein the supporting portion and the connecting portion are detachably connected, and the two axial ends of the brush are connected to the connecting portion through a connecting component;

[0009] Wherein, a driving member is further provided on the side of the connecting portion, and the driving member is used to drive the brush to rotate.

[0010] Furthermore, the support portion is a plate-shaped structure and is provided in pair, the pair of support portions are provided correspondingly, and the lower ends of the pair of support portions are provided with connecting bosses, and steps are formed between the two sides of the connecting bosses and the support portion;

[0011] Wherein, the two sides of the connecting boss have protrusions, and a recessed portion is also provided inside the connecting boss.

[0012] Furthermore, the connecting portion is in a U-structure and extends downward between the two side extensions to form a plug-in portion, and the connecting portion is engaged with the connecting boss so that the plug-in portion is plugged into the recessed portion.

[0013] Furthermore, the extensions on both sides of the connecting portion are in contact with the step portion, and corresponding grooves are provided between opposite surfaces of the extensions on both sides, and the grooves are engaged with the protrusions.

[0014] Furthermore, the connecting component is a roller bearing, the outer peripheral key of the brush shaft end is connected to the roller bearing, and the brush is rotatably connected to the connecting part.

[0015] Furthermore, the driving member is a motor, the motor is fixedly mounted on the side of the support portion, and the motor shaft end is fixedly connected to the brush shaft end.

[0016] The utility model proposes a rotatable glue brush, which has the beneficial effect that: the utility model uses a roller bearing instead of a screw locking method to make the brush rotatably connected to the bracket, and by changing the brush fixing method, the glue brushing movement mode can be changed, which can effectively prevent the squeezed glue liquid from accumulating in one place to form large hard glue particles, avoid the glue particles from scratching the battery cell, and avoid poor glue brushing due to brush deformation. It can also reduce the frequency of manual inspections and brush replacements, reduce labor costs, and effectively ensure product quality and stable output. In addition, the brush and the connecting part are detachably connected, and the connecting part and the supporting part can also be quickly disassembled and assembled, which is convenient for disassembly and cleaning of the brush to prevent glue accumulation and solidification.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-3 A rotatable glue brush comprises a bracket 1 and a brush 2 arranged in the bracket 1, wherein the bracket 1 comprises a supporting portion 11 and a connecting portion 12, wherein the supporting portion 11 and the connecting portion 12 are detachably connected, and the two axial ends of the brush 2 are connected to the connecting portion 12 via a connecting component 3;

[0023] A driving member 4 is further provided on the side of the connecting portion 12 , and the driving member 4 is used to drive the brush 2 to rotate.

[0024] It should be added that the other end of the bracket 1 is connected and fixed to an external driving device. When the battery cell is wound, the winding needle rotates the unsealed bare battery cell to a certain position, and then the stacking machine gives a glue brushing signal. The brush is driven to rotate by a servo motor and the brush position is lowered by the driving device. The rotation of the brush is used to stick the diaphragm to the side of the bare battery cell, and at the same time, the glue can be prevented from accumulating in one place.

[0025] Furthermore, the support portion 11 is a plate-shaped structure and is provided in pair. The pair of support portions 11 are provided correspondingly, and a connecting boss 111 is provided at the lower end thereof. Step portions 112 are formed between the two sides of the connecting boss 111 and the support portion 11.

[0026] The connecting boss 111 has protrusions 113 on both sides and a recessed portion 114 inside.

[0027] Furthermore, the connecting portion 12 is in a U-structure and extends downward between the two side extensions to form an inserting portion 121 . The connecting portion 12 is engaged with the connecting boss 111 so that the inserting portion 121 is inserted into the recessed portion 114 .

[0028] In more detail, the extensions on both sides of the connecting portion 12 are in contact with the step portion 112 , and corresponding grooves 122 are provided between the opposite surfaces of the extensions on both sides, and the grooves 122 are engaged with the protrusions 113 .

[0029] It should be noted that the connecting portion 12 is preferably made of a material with plastic deformation ability, such as plastic or rubber. That is, the extended portions on both sides of the connecting portion 12 have the ability to deform to avoid being stuck when being interfered with by the protrusion 113, and to ensure that the groove 122 can be engaged with the protrusion 113.

[0030] It is worth mentioning that the insertion of the plug-in portion 121 and the recessed portion 114 can limit the brush 2 laterally, preventing the brush 2 from driving the connecting portions 12 on both sides to slide laterally on the support portion 11, causing the groove 122 and the protrusion 113 to lose their meaning;

[0031] Moreover, after being plugged in, the groove 122 and the protrusion 113 are engaged to limit the brush 2 laterally, preventing the connecting portion 12 from being separated from the supporting portion 11, thereby facilitating the disassembly and cleaning of the brush 2.

[0032] In general, the connecting component 3 is a roller bearing, the outer peripheral key of the axial end of the brush 2 is connected to the roller bearing, and the brush 2 is rotatably connected to the connecting portion 12.

[0033] Specifically, the brush 2 is fixed by the rotatable roller bearing instead of the traditional screw locking fixing method, so as to prevent the brush 2 from being locked and avoid the situation where only one side is brushed with glue and the contact surface is small.

[0034] Finally, the driving member 4 is a motor, and the side surface of the support portion 11 is fixedly mounted with the motor, and the shaft end of the motor is fixedly connected to the shaft end of the brush 2 .

[0035] Specifically, in the traditional operation method, due to the locking of the brush, the bare battery cell needs to be rotated for glue brushing. The present application replaces the bare battery cell rotating glue brushing method with the rotating brush brushing method, which improves the glue brushing efficiency while ensuring the glue brushing quality.

[0036] Working mode: When working, the shaft end key of the brush 2 is connected to the roller bearing and is rotatably connected to the connecting portion 12 through the roller bearing;

[0037] Then, the connecting portion 12 is engaged with the supporting portion 11, so that the plug-in portion 121 is plugged into the recessed portion 114. At the same time, the extended portions on both sides of the connecting portion 12 utilize plastic deformation force to engage the grooves 122 of the extended portions with the protrusions 113, thereby achieving the function of limiting and fixing the brush 2.

[0038] During operation, the winding needle rotates the unsealed bare battery cell to a certain position, and then the stacking machine gives a glue brushing signal. The brush is driven by the servo motor to rotate and start to descend. The servo motor drives the brush to rotate and fit the diaphragm to the side of the bare battery cell.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
