Description

Technical Field

[0001] This utility model relates to the field of lithium battery spray adhesive curing, specifically, to a device for lithium battery spray adhesive curing. Background Technology

[0002] In lithium battery production, adhesive spraying and curing are critical process steps that directly affect the battery's airtightness and safety. Currently, existing technologies mainly employ pneumatic valve adhesive spraying combined with thermosetting, relying on manual operation for material feeding, dispensing, and curing. Specifically, traditional technical solutions have the following problems and shortcomings:

[0003] (1) Problems with the glue spraying process: Traditional glue dispensing machines use pneumatic valves for glue spraying. The amount of glue dispensed by pneumatic valves fluctuates greatly, resulting in uneven glue layer thickness, which in turn affects the airtightness of the battery and may even cause safety hazards.

[0004] (2) Curing process issues: Traditional dispensing machines use thermal curing, which takes a long time (usually more than two minutes), consumes a lot of energy, and loses a lot of heat, resulting in low production efficiency; in addition, uneven thermal curing time will also affect the airtightness of lithium batteries.

[0005] (3) Manual operation problem: The existing equipment can only achieve semi-automatic operation. Most of them use manual feeding with a single material tray combined with mechanical dispensing and curing. Improper operation may lead to uneven lighting and some colloids not being fully cured, which affects battery performance and safety.

[0006] The aforementioned problems severely restrict the efficiency and quality of lithium battery production, and there is an urgent need for a spray adhesive curing equipment that can achieve automation, high precision, and high energy efficiency. Utility Model Content

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0040] like Figures 1 to 8 As shown, this utility model addresses the problems of excessive manual intervention, high energy consumption, low efficiency, and insufficient yield in the existing lithium battery spray adhesive curing process by proposing a lithium battery spray adhesive curing device. This device solves the problem of poor workflow by automatically connecting the feeding and unloading processes. It also strictly controls the uneven adhesive dispensing volume during the dispensing process using piezoelectric valves, which leads to inconsistent adhesive layer thickness. Finally, it utilizes UV curing to reduce curing time and save energy.

[0041] The specific solution for the lithium battery spray adhesive curing equipment in this utility model is as follows: The lithium battery spray adhesive curing equipment includes a feeding component, a dispensing conveying component, a dispensing component, a curing component, and a unloading component connected in sequence.

The linkage pusher 160 is mounted on the servo linkage base 110 through the linkage slide rail 170 and reciprocates along the linkage slide rail 170.

[0045] During the feeding process, the servo motor 120 drives one central shaft of the rotating component 130 to rotate.

[0046] 2. Dispensing and conveying assembly

[0047] like Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the dispensing conveying assembly 200 includes a conveying platform 210, and also includes a multi-station pushing assembly 220 and multiple clamping assemblies 230. In this utility model, the dispensing stations include at least three, so the multi-station pushing assembly 220 includes components for pushing the lithium battery to the three dispensing stations, and there are also three clamping assemblies 230.

[0048] The conveyor platform 210 is used to connect the feeding component and the multi-station push component 220. It is a structure in which the conveyor motor drives the conveyor belt. It can also be other conveying structures, which will not be described in detail here.

[0052] In this invention, three dispensing stations, three push arms 226, and three grippers 233 can simultaneously dispense adhesive onto three lithium batteries, improving processing efficiency. The clamping assembly 230 positions and holds the lithium batteries during the dispensing process, preventing misalignment and ensuring effective dispensing. Furthermore, the dispensing delivery assembly 200 completely replaces manual labor in placing and positioning the lithium batteries for dispensing, improving efficiency and saving labor costs.

This structure can adopt conventional designs in the industry and will not be described in detail here.

[0056] 4. Curing components

[0057] The curing assembly 400 is located at the outlet end of the dispensing assembly 300. The curing assembly 400 includes a curing chamber 410 and a UV curing lamp 440 located inside the curing chamber. The curing chamber 410 shields the lithium battery during the curing process to prevent light leakage. This invention uses UV curing, which greatly reduces the curing time of the adhesive and saves energy compared to traditional thermal curing.

[0058] The curing assembly 400 also includes a housing 430 and an air-cooling assembly 420. The UV curing lamp 440 is located at the bottom of the housing 430, and the air-cooling assembly 420 is located at the top of the housing 430. It is used to dissipate heat from the back of the UV curing lamp 440 and inside the housing 430 to ensure that the curing assembly 400 is in a good working environment.

[0059] 5. Material feeding assembly

[0060] This utility model also includes a feeding component, which is located at the discharge end of the curing component 400 and is used to feed the lithium battery after dispensing and curing, so as to achieve docking with the subsequent work station.

[0061] Both the curing assembly 400 and the discharge end of the unloading assembly are equipped with linkage mechanisms for steering the lithium battery. These linkage mechanisms can have the same structure as the servo linkage assembly 100 in the loading assembly, and will not be described in detail here. In this invention, the linkage mechanism inside the curing assembly 400 can convert the lithium battery moving in the X-axis direction to move in the Y-axis direction. By steering the lithium battery, the distance it moves within the curing assembly can be extended, ensuring sufficient curing time. The linkage mechanism at the discharge end of the unloading assembly can convert the lithium battery moving in the Y-axis direction to move in the X-axis direction, changing the unloading line to reduce the overall width of the equipment and also matching the loading direction of subsequent processes.
