Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary adhesive application devices, and in particular to an auxiliary adhesive application device for battery assembly process. Background Technology
[0002] In the battery assembly process, the adhesive application process is a crucial step in ensuring battery structural stability, insulation protection, and a neat appearance. Whether it's a power battery or an energy storage battery, insulating adhesive, fixing adhesive, or marking adhesive (usually 0.1-0.5mm thick) must be applied to areas such as the casing seams, around the terminals, and wiring terminals to prevent short circuits (short circuit failure rate can be reduced to below 0.1%), mitigate vibration and shock (vibration acceleration tolerance increased by 20%-30%), and meet standardized marking requirements. Existing auxiliary adhesive application devices used in battery assembly processes suffer from several drawbacks. Manual adhesive application relies on experience, resulting in positioning deviations of up to ±1mm. For precision areas of small batteries (<100mm×50mm) such as the edge of the terminal post, adhesive misalignment can easily occur, covering functional areas (over 5%) and damaging battery performance (insulation resistance decreases by 10%-15%). Furthermore, some semi-automatic adhesive application tools lack cushioning design, leading to uneven adhesive pressure (pressure fluctuations of ±0.5N), which can generate bubbles (over 8%) or wrinkles (over 10%), affecting protective effectiveness and appearance quality. Therefore, solutions to these technical problems are needed. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary adhesive applicator for the battery assembly process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Example: See Figures 1 to 4 This utility model discloses an auxiliary adhesive application device for battery assembly, comprising a battery 1 placed on top of a movable base 2. Multiple limiting plates 15 are fixedly connected to the upper perimeter of the movable base 2. A film application mechanism is installed on one side of the movable base 2, and a moving mechanism is installed on the other side of the film application mechanism. A scraping mechanism is also mounted on the film application mechanism. Through the battery 1, movable base 2, limiting plates 15, film application mechanism, moving mechanism, and scraping mechanism, auxiliary adhesive application during battery assembly is easily achieved. A support plate 3 is horizontally installed on one side of the movable base 2. The lower end of the support plate 3 is vertically fixed with rectangular support columns around its perimeter. The support plate 3 on one side of the movable seat 2 and the support columns at its lower end provide installation support for the moving mechanism and the film application mechanism. The moving mechanism includes a magnetic shaft linear motor 9 mounted on the upper end of the support plate 3. A second electric telescopic rod 8 is mounted on the upper end of the magnetic shaft linear motor 9. A fixing block 14 is mounted on the output end of the second electric telescopic rod 8 through a fixing nut. The magnetic shaft linear motor 9, the second electric telescopic rod 8 and the fixing block 14 on the support plate 3 facilitate the movement of the film application mechanism.
[0015] In this invention, a moving groove is provided on the support plate 3 between the magnetic shaft linear motors 9. A moving block 4 is slidably installed in the moving groove. One side of the moving block 4 is connected and fixed to the fixed block 14 by bolts. The moving groove and the moving block 4 on the support plate 3 facilitate the movement of the film-applying mechanism. The film-applying mechanism includes a guide rod 10 fixed to the upper end of the moving block 4. A sliding seat is slidably engaged at the upper end of the guide rod 10. A push rod 6 is bolted to the upper end of the sliding seat. One end of the push rod 6 is fixed to an adhesive block 11. The other end of the push rod 6 passes through the moving block 4 and is fixed to a positioning rod. One end of the positioning rod is threadedly connected to an anti-detachment cap. A first telescopic spring 12 is sleeved between the movable block 4 and the push rod 6. The guide rod 10, sliding seat, push rod 6, adhesive block 11, positioning rod and first telescopic spring 12 on the movable block 4 facilitate the application of adhesive. The scraping mechanism includes a scraping block fixed to one side of the movable block 4. A second telescopic spring 13 is connected between the scraping block and the push rod 6. A groove is opened on one side of the scraping block. A first electric telescopic rod 5 is installed in the groove. The output end of the first electric telescopic rod 5 is fixed to an adhesive roller 7. The scraping block, second telescopic spring 13, first electric telescopic rod 5 and adhesive roller 7 on one side of the movable block 4 facilitate the scraping and compaction of the applied side adhesive.
[0016] Working Principle: In the use of this utility model, firstly, the battery 1 to be glued is placed on the movable seat 2 and positioned by the limiting plate 15 to ensure accurate glue application. The adhesive strips required for battery assembly are prepared, and simultaneously, one end of the adhesive strip is fixed to the glue application block 11 by an external adhesive strip cutting device. The relative position of the glue application block 11 and the battery 1 is adjusted to prepare for the glue application operation. Then, the magnetic shaft linear motor 9 is started, driving the second electric telescopic rod 8 and the fixed block 14 to move horizontally. Since the movable block 4 is connected to the fixed block 14, the movable block 4 slides synchronously along the moving groove of the support plate 3, thereby adjusting the horizontal position of the film application mechanism and the scraping mechanism, and positioning the glue application block... Align the starting position of the adhesive application block 11 with the battery 1, and according to the adhesive application requirements of the battery 1, activate the second electric telescopic rod 8. The output end then drives the moving block 4 to move, thereby adjusting the adhesive application pressure of the adhesive application block 11 to ensure that the adhesive application block 11 is in close contact with the surface of the battery 1. At the same time, the scraping mechanism moves synchronously with the moving block 4. Then, activate the first electric telescopic rod 5, and push the application roller 7 out of the groove through the output end to contact the surface of the adhesive strip. The elastic force of the second telescopic spring 13 maintains the gap between the push rod 6 and the scraping block. Then, as the moving block 4 moves, the application roller 7 rolls along both sides of the adhesive strip, thereby adhering the adhesive strip to both sides of the battery 1 and ensuring that the adhesive strip is firmly adhered.
[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
