Technical Field
[0001] This utility model relates to the technical field of semi-automatic hot melt adhesive dispensing machines, and in particular to a semi-automatic hot melt adhesive dispensing machine for fixing automotive battery electrode groups. Background Technology
[0002] A hot melt adhesive dispensing machine is an automated device specifically designed to heat hot melt adhesive to a liquid state and then apply or spray it onto specific locations using precise control. It is widely used in manufacturing, especially in applications requiring rapid curing and environmentally friendly solvent-free evaporation, such as automobile manufacturing, electronic product assembly, and packaging. With the development of the automotive industry and increasingly stringent environmental requirements, lead-acid batteries, as a crucial component of automotive starting power, have received widespread attention for their performance and reliability. The electrode group (positive and negative plates) inside a lead-acid battery is one of its core components, and the fixation and sealing between the electrode groups are vital to ensuring the overall performance of the battery. Therefore, in the automotive battery production process, employing efficient, precise, and environmentally friendly hot melt adhesive dispensing technology to achieve stable fixation and sealing of the electrode groups has become a key step in improving battery quality and production efficiency.
[0003] Traditionally, assembly of products is mainly carried out by manual application of glue, mechanical clamps, or welding. Among these methods, manual application of glue is not only time-consuming and labor-intensive, but also makes it difficult to ensure the uniformity and consistency of the glue application, which can easily lead to fluctuations in product quality. While fully automatic dispensing machines on the market can improve production efficiency, their complex structure and high maintenance costs make them expensive and unaffordable for small and medium-sized enterprises, thus limiting their widespread promotion and application in the industry.
[0004] Therefore, it is necessary to design a semi-automatic hot melt adhesive dispensing machine for fixing automotive battery electrode groups in order to solve the above-mentioned technical problems. Utility Model Content

[0026] like Figure 4 and Figure 6As shown, it also includes a clamping ring 701, a flipping ring 702 and a locking block 703. The clamping ring 701 is installed at the top front end of the fixing frame 7 by screws. The front part of the clamping ring 701 is rotatably connected to the flipping ring 702 by a hinge. The left side of the flipping ring 702 is provided with a locking block 703, which slides with the flipping ring 702.
[0027] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes a glue bucket 9, a flip cover 10, a glue outlet 11, an HMI 12, a start button 13, a glue machine power switch 14, and an electrical control cabinet door 15. The glue bucket 9 is placed on the left side of the workbench 1. The flip cover 10 is located on the rear side of the top of the glue bucket 9. The glue outlet 11 is located on the lower rear side of the glue bucket 9. The HMI 12 is installed on the front side of the top of the glue bucket 9.

The electrical control cabinet door 15 is located at the front of the glue bucket 9.
[0028] like Figure 4 and Figure 7 As shown, it also includes a servo motor 16, a lead screw 17, a limit plate 18, an adjusting rod 19, a clamping plate 20, and a limit rod 21. The servo motor 16 is installed on the right side of the worktable 1 by screws. The output shaft of the servo motor 16 is connected to the lead screw 17. The left and right sides of the lead screw 17 are threaded to the limit plates 18 respectively. The two limit plates 18 are rotatably connected to the opposite sides of each other.

The control switch 8 is electrically connected to the servo motor 16.
[0029] When the device is needed, first, open the electrical control cabinet door 15 and check whether the internal electrical wiring is connected normally. Then, turn on the glue machine power switch 14 to turn on the equipment power. Next, open the flip cover 10 of the glue tank 9, add an appropriate amount of hot melt adhesive granules to the glue tank 9, and set parameters such as heating temperature, dispensing path, and dispensing speed through HMI12. Place the automotive battery electrode assembly to be fixed on the heating platform 2, open the flip ring 702 at the front of the clamping ring 701, put the electrode assembly into the clamping ring 701, close the flip ring 702, and lock it in place using the locking block 703. Then, press the start button 1. 3. Heating platform 2 begins heating to the set temperature, and servo motor 16 is started. Servo motor 16 drives lead screw 17 to rotate, causing the left and right limit plates 18 to move along lead screw 17. If the clamping width needs to be adjusted, the adjusting rod 19 can be manually rotated to move clamping plate 20 closer to or further away from the electrode assembly, completing the clamping and positioning. Clamping plate 20 and limit plate 18 slide together to ensure stable and reliable clamping. Both limit plate 18 and clamping plate 20 are made of hard alloy material, which has high strength and wear resistance, and is suitable for frequent clamping operations.

The system consists of three sliding rails: 4 (movable rail 2) and 5 (electric sliding rail 3). Electric sliding rail 3 controls electric slider 301 to move horizontally (X-axis); electric sliding rail 4 controls electric slider 401 to move forward / backward (Y-axis); and electric sliding rail 5 controls electric slider 301 to move vertically (Z-axis). These three sets of rails and sliders together form a three-degree-of-freedom motion platform, driving the glue-applying valve 6 to precisely reach any point. Electric sliders 301, 401, and 501 are all made of polyoxymethylene (POM), which has good wear resistance and self-lubricating properties, effectively improving sliding accuracy. After determining the service life, the glue dispensing valve 6 is opened, and hot melt adhesive is delivered from the glue tank 9 through the glue outlet 11 to the glue dispensing valve 6 and heated to a liquid state. The glue dispensing valve 6 performs precise glue dispensing operation on the designated position of the electrode group according to the preset path. After the glue dispensing is completed, the glue dispensing valve 6 is closed, and the control system drives the three sets of slide rails to reset to the initial position. Then, the heating system is turned off, and the heating table 2 is allowed to cool down. The locking block 703 is released, the flipping ring 702 is flipped, the electrode group component that has been glued is taken out, the residual glue is cleaned, and the equipment components are checked for normal operation. If it is necessary to continue operation, the above steps are repeated; otherwise, the power is turned off and the electrical control cabinet door 15 is closed.
