Description

Technical Field

[0001] The utility model relates to the technical field of battery adhesive application, in particular to an adhesive application mechanism for lithium battery bottom adhesive application equipment. Background Art

[0002] As an important secondary battery energy storage system, lithium-ion batteries have the advantages of high energy density, long cycle life and wide operating temperature range. According to the structure, lithium-ion batteries can be divided into three categories: cylindrical cells, hard-shell cells and soft-pack cells. Among them, soft-pack cells have the advantages of simple structure and high energy density, and are widely used in the 3C and power battery fields. The production and manufacturing process of soft-pack cells can be divided into the electrode segment, assembly segment and formation segment. In the assembly segment, the electrodes are stacked to form a soft-pack bare cell body. After the side of the bare cell body is fixed with glue, it flows into the next step of hot pressing, packaging and other processes. The quality of the side glue is crucial to the normal operation of the back-end process. Cells with poor glue often have problems such as electrode warping, wrinkles and poor contact, and will therefore be identified and scrapped.

[0003] Among them, the application number CN202322585470.6 provides a new type of battery cell gluing mechanism, which relates to the field of battery cell production technology. The battery cell gluing mechanism includes: a frame; a first rod, which is arranged on the frame and has a roller on the first rod; a second rod, which is arranged on the frame and has a roller on the second rod, and the roller on the first rod and the roller on the second rod are arranged relative to each other; a third rod, which is arranged on the frame and located between the first rod and the second rod, and the end of the third rod away from the frame moves along the length direction of the third rod when an external force is applied; a reset member, which is configured to apply a force opposite to the external force, so that when the external force is less than the force applied by the reset member, the end of the third rod away from the frame is reset. When gluing the battery cell, the roller presses the tape onto the battery cell. On the one hand, the roller smoothes the tape, which can effectively reduce problems such as tape bridging, wrinkles and overlap. On the other hand, the pressure applied to the battery cell by the roller during gluing is less than the pressure of direct extrusion gluing, and the interference with the battery cell electrode is smaller.

[0004] Existing adhesive tape application systems can only apply adhesive to one side of a battery cell and are unable to apply double-sided tape. Manually placing the tape rolls at the unloading station is tedious, and existing systems lack a standard for adhesive tape application. When precision adhesive application is required, existing systems cannot meet these requirements. Summary of the Invention

[0005] The purpose of the utility model is to provide a glue sticking mechanism for a lithium battery bottom glue sticking device in response to the deficiencies in the prior art.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] The gluing mechanism of the lithium battery bottom glue sticking equipment includes a gluing drive seat that can move horizontally and vertically. The gluing drive seat is provided with a horizontally arranged positioning seat for horizontally supporting the battery. The top and bottom surfaces of the positioning seat are respectively slidably mounted with a glue rolling assembly. The glue rolling assembly includes a glue pressing roller and a glue pressing seat. The outer end surface of the glue pressing seat is used to position the tape. When the glue pressing seat moves horizontally, the tape is tightly attached to the surface of the battery through the bottom surface of the glue pressing seat.

[0008] Furthermore: a plurality of adsorption holes for adsorbing the adhesive tape are provided on the outer end surface of the adhesive pressing seat.

[0009] Furthermore: the glue rolling assembly also includes a glue rolling drive seat, which is respectively equipped with the glue pressing roller and the glue pressing seat, and the glue rolling drive seat is provided with an elastic driving structure that drives the glue pressing roller to elastically press against the lateral end surface of the glue driving seat.

[0010] Furthermore: the elastic drive structure includes a rubber roller drive seat installed on the rubber roller drive seat, a rolling drive groove is opened at the bottom of the rubber roller drive seat, the rubber roller drive seat is equipped with a mounting bracket that can swing longitudinally, and the rubber pressure roller is rotatably installed at the bottom of the mounting bracket.

[0011] Furthermore: a compression spring is provided between the adhesive driving seat and the mounting bracket.

[0012] Furthermore: a first mounting hole is formed transversely on the outer end face of the rubber rolling drive seat, a second mounting long hole is formed on the rubber pressing seat which is coaxial with the first mounting hole, the second mounting long hole extends longitudinally, and the rubber pressing seat can be installed on the outer end face of the rubber rolling drive seat with an adjustable height.

[0013] Furthermore: the glue driving seat is provided with a transverse driving member that drives the glue rolling assembly to move laterally along the glue driving seat. The transverse driving member includes transverse driving seats that are respectively slidably installed on the top and bottom surfaces of the glue driving seat, and a longitudinal connecting plate is connected between the two transverse driving seats.

[0014] Furthermore: the transverse driving member also includes a guide rail arranged along the length direction of the rubber driving seat, the guide rail is slidably installed with a guide sliding seat, and the guide sliding seat is connected to the transverse driving seat; the rubber driving seat is arranged along the length direction with a transverse telescopic cylinder, and the transverse telescopic cylinder is connected to the longitudinal connecting plate.

[0015] Furthermore: the glue sticking mechanism also includes a glue sticking drive mechanism that drives the glue sticking drive seat to move horizontally and vertically.

[0016] The beneficial effects of the present invention are as follows: when applying glue, the two sets of glue rolling assemblies move simultaneously. The glue pressing seat first bends the tape attached to the side of the battery 90 degrees to the surface, so that the upper half of the tape is attached to the top surface of the battery and the lower half of the tape is attached to the bottom surface of the battery. Then, the glue pressing roller rolls with the top and bottom surfaces of the battery to roll the initially attached tape, thereby improving the adhesion stability between the tape and the battery and preventing the tape from falling off the battery. There is no need to move the battery cell. The glue applying mechanism can realize a U-shaped glue applying method and can apply glue to multiple surfaces of a product. It can ensure a certain degree of accuracy in the glue applying function. It is also relatively convenient to collect and release materials. Maintenance and debugging are relatively convenient.

[0030] The present invention is described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-3As shown, the gluing mechanism of the lithium battery bottom glue gluing equipment includes a gluing drive seat 1 that can move horizontally and vertically. The gluing drive seat 1 is provided with a horizontally arranged positioning seat 12 for horizontally supporting the battery. The top and bottom surfaces of the positioning seat 12 are respectively slidably mounted with a glue rolling assembly 11. The glue rolling assembly 11 includes a glue pressing roller 24 and a glue pressing seat 13. The outer end surface of the glue pressing seat 13 is used to position the tape. When the glue pressing seat 13 moves horizontally, the tape is tightly attached to the surface of the battery through the bottom surface of the glue pressing seat 13.

[0032] When applying glue, the two sets of glue rolling assemblies 11 move simultaneously. The glue pressing seat 13 first bends the tape attached to the side of the battery 90 degrees to the surface, so that the upper half of the tape is attached to the top surface of the battery and the lower half of the tape is attached to the bottom surface of the battery. Then the glue pressing roller 24 rolls with the top and bottom surfaces of the battery to roll the initially attached tape, thereby improving the adhesion stability between the tape and the battery and preventing the tape from falling off the battery. There is no need to move the battery cell. The glue applying mechanism can realize U-shaped glue application and can apply glue to multiple surfaces of a product. It can ensure a certain degree of accuracy of the glue application function. It is also relatively convenient to collect and release materials. Maintenance and debugging are relatively convenient.

[0033] The outer end surface of the glue pressing seat 13 is provided with a plurality of adsorption holes 14 for adsorbing the tape; initially, after the tape is in place, the upper and lower parts of the tape are respectively adsorbed and positioned through the adsorption holes 14 of the glue pressing seat 13, and then the battery is laterally approached to the side of the positioning seat 12 where the tape is positioned, and then the side of the battery is attached to the middle of the tape and presses the positioning seat 12 at the same time, waiting for subsequent attachment.

[0034] The rubber rolling assembly 11 also includes a rubber rolling drive seat 15, on which the rubber rolling drive seat 15 is respectively installed with the rubber pressing roller 24 and the rubber pressing seat 13. The rubber rolling drive seat 15 is provided with an elastic driving structure 2 that drives the rubber pressing roller 24 to elastically press against the lateral end surface of the rubber applying drive seat 1; the elastic driving structure 2 includes a rubber roller driving seat 21 installed on the rubber rolling drive seat 15, and a rolling driving groove 22 is provided at the bottom of the rubber roller driving seat 21. The rubber roller driving seat 21 is installed with a mounting bracket 23 that can swing longitudinally through the rolling driving groove 22 and the structure of the shaft hole, and the rubber pressing roller 24 is rotatably installed at the bottom of the mounting bracket 23 through the shaft hole structure; a compression spring 25 is provided between the rubber applying drive seat 1 and the mounting bracket 23. In this embodiment, initially, the glue roller driving seat 15 does not extend outward, and the mounting bracket 23 installed on the glue roller driving seat 21 is elastically driven by the compression spring 25, and the mounting bracket 23 will swing downward, so that the glue pressing roller 24 installed at the bottom of the mounting bracket 23 will press against the top or bottom surface of the positioning seat 12; after moving horizontally, the glue pressing roller 24 will be elastically driven by the compression spring 25 and will adaptively press against the positioning seat 12 and the battery surface according to the height, so that the tape can be quickly attached to the battery cell, thereby increasing the glue sticking efficiency and ensuring the glue sticking quality.

[0035] Preferably, a first mounting hole 16 is formed transversely on the outer end surface of the rubber rolling drive seat 15, and a second mounting long hole 17 is formed on the rubber pressing seat 13 which is coaxial with the first mounting hole 16. The second mounting long hole 17 extends longitudinally, and the rubber pressing seat 13 is mounted on the outer end surface of the rubber rolling drive seat 15 with adjustable height; when the thickness of the battery is different, the height of the rubber pressing seat 13 needs to be adjusted, and the first mounting hole 16 and the second mounting long hole 17 are connected by screws for adjusting the height of the rubber pressing seat 13.

[0036] The glue-applying drive seat 1 is provided with a transverse driving member 3 that drives the glue rolling assembly 11 to move transversely along the glue-applying drive seat 1. The transverse driving member 3 includes transverse driving seats 31 that are respectively slidably installed on the top and bottom surfaces of the glue-applying drive seat 1, and a longitudinal connecting plate 32 is connected between the two transverse driving seats 31; under the connection of the longitudinal connecting plate 32, the transverse driving seats 31 located at the top and bottom of the glue-applying drive seat 1 can move laterally synchronously at the same time, and the two glue rolling assemblies 11 move at the same time to achieve simultaneous gluing of the top, bottom and side surfaces of the battery.

[0037] Furthermore, the transverse driving member 3 also includes a guide rail 33 arranged along the length direction of the glue driving seat 1, and the guide rail 33 is slidably installed with a guide sliding seat 34, and the guide sliding seat 34 is connected to the transverse driving seat 31; the glue driving seat 1 is provided with a transverse telescopic cylinder 35 along the length direction, and the transverse telescopic cylinder 35 is connected to the longitudinal connecting plate 32; the transverse telescopic cylinder 35 drives the longitudinal connecting plate 32 to move transversely, and the transverse driving seat 31 moves along the guide rail 33 through the guide sliding seat 34, further improving the stability of the transverse movement.

[0038] The gluing mechanism also includes a gluing drive mechanism that drives the gluing drive seat 1 to move horizontally and vertically. The gluing drive mechanism can be coordinated with linear modules arranged horizontally and vertically to achieve horizontal and vertical movement.

[0039] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.
