[0003] Currently, the application of insulating strips to battery cells is mainly done using specialized adhesive application equipment tailored to different cell models. While this process is semi-automated compared to manual operation, it still struggles to achieve full automation and continuous operation. Furthermore, existing adhesive application equipment suffers from low compatibility. Different shapes and sizes of battery cells require separate handling of relevant parts, and each process necessitates replacement, adjustment, and setting of actual pressure parameters before each application. Otherwise, issues such as adhesive deviation, weak adhesion, air bubbles, wrinkles, or damage to the battery cell can easily occur. Even for the same type of battery cell, the required adhesive application location varies depending on the application scenario. Therefore, existing adhesive application equipment generally suffers from low processing efficiency, poor compatibility, complex operation, and low adhesive quality. Summary of the Invention

[0026] Example 1

[0027] This embodiment provides a battery cell insulation strip adhesive application device, including: an adhesive supply mechanism 100, which includes an adhesive application component 110 and an adjustment component 120 disposed on the adhesive application component 110; an adhesive application mechanism 200, which is spaced apart from the adhesive supply mechanism 100 along the insulation strip transmission direction, and includes a lifting component 210 and an adhesive application component 220 that move relative to each other along the height direction of the device, wherein the lifting component 210 includes a lifting platform 212, and the adhesive application component 220 includes an extrusion component 224 that moves up and down above the lifting platform 212, and the extrusion component 224 is provided with a pressure-pressurizing and stationary mechanism 225, the working time of the pressure-pressurizing and stationary mechanism 225 not exceeding 5 seconds; and a transmission mechanism 300, which includes at least one bearing fixture 320 that can be positioned on the lifting platform 212, and the bearing fixture 320 is provided with at least one battery cell position point.

[0028] The battery cell insulation strip adhesive application equipment of the present invention adjusts the position of the insulation strip through the adhesive supply mechanism 100, and then completes the adhesive application through the cooperation of the extrusion member 224 and the lifting platform 212 in the adhesive application mechanism 200. At the same time, the battery cell 500 to be adhesiveped is continuously transported to the adhesive application mechanism 200 through the transmission mechanism 300. This achieves fully automated, efficient and precise adhesive application operation. Most importantly, the pressure-pressurizing and stationary mechanism 225 in this equipment and its limitation on the extrusion speed can overcome the problems of low processing efficiency, poor compatibility, complex operation and low adhesive application quality in the prior art. It is a new type of battery cell insulation strip adhesive application equipment with broad application prospects.

[0029] See Figure 1 and Figure 2 As shown, the battery cell insulation strip adhesive application equipment in this embodiment also includes a housing 400. The housing 400 includes a support frame 420 and a top cover 410. The top cover 410 can be fastened to the support frame 420 and together with the support frame 420, it encloses a processing space for accommodating the adhesive supply mechanism 100, the adhesive application mechanism 200, and the transmission mechanism 300. Further, with... Figure 1 The battery cell insulation strip pasting equipment shown is a reference. The transmission mechanism 300 passes through the top cover 410 along the width of the housing 400. Both ends of the top cover 410 are used for loading and unloading operations. The top cover 410 is also provided with an observation window to facilitate real-time observation of the internal operation of the equipment. The support frame 420 is located below the top cover 410 to provide overall support for the equipment. Multiple storage cabinets can be set inside the support frame 420 to store maintenance parts or tools. In this embodiment, a connector is provided between the top cover 410 and the support frame 420 to connect the two. The connector is preferably a snap fastener.

[0030] by Figure 2The battery cell insulation strip applicator shown is a reference example. The adhesive supply mechanism 100, adhesive application mechanism 200, and transmission mechanism 300 are arranged sequentially from left to right. The adhesive supply mechanism 100 continuously feeds the insulation strips into the equipment at a specific speed and adjusts the shape and application position of the insulation strips. The adhesive application mechanism 200 connects the insulation strips and the battery cells 500 to be applicated, completing the application. The transmission mechanism 300 continuously transports the carrier fixture 320, which holds the battery cells 500 to be applicated, into the processing space, thereby maximizing the processing efficiency of the equipment. Furthermore, the equipment includes a recycling table 330 for collecting and storing defective products.

[0031] See Figure 2 As shown, in this embodiment, the glue application component 110 and the adjustment component 120 in the glue supply mechanism 100 are arranged sequentially along the direction of insulating glue transmission. The glue application component 110 is used to input the rolled insulating glue strip into the device, and the adjustment component 120 is used to adjust the insulating glue strip so that it can be applied to different models or shapes of battery cells 500 according to the actual situation.

[0032] See Figure 3 As shown, the gluing assembly 110 includes at least one winding module 111 and at least one glue feeder 112 correspondingly disposed at the discharge end of the winding module 111. In this embodiment, two winding modules 111 are spaced apart along the width of the equipment. The two winding modules 111 can work simultaneously to significantly improve their glue supply efficiency. Correspondingly, two glue feeders 112 carrying insulating adhesive strips are provided at the glue discharge ends of the two winding modules 111. In other embodiments, more winding modules 111 can be provided according to actual needs. Furthermore, to reduce costs, one glue feeder 112 can also be provided for two or more winding modules 111. Further, in this embodiment, any winding module 111 is fed by rotation, and after feeding, it is received by the glue feeder 112. The glue feeder 112 is provided with a support slider that can move along the length of the equipment. The support slider can move synchronously with the insulating adhesive strip on the glue feeder 112 to achieve the purpose of conveying the insulating adhesive strip to the next working point.

[0033] See Figure 2 and Figure 4 As shown, the adjusting component 120 can move above the glue dispenser 112. Specifically, it can move along the length, width, and height directions of the device, thereby adjusting the actual pasting position of the insulating strip. See [link to documentation]. Figure 4As shown, the adjustment assembly 120 includes an adsorption element, a first moving module 121 extending along the transmission direction of the insulating strip, a second moving module 122 located in the same horizontal plane as the first moving module 121 and arranged perpendicularly to each other, and a first lifting module 123 that moves up and down along the height direction of the device. The second moving module 122 is disposed on the first moving module 121, the first lifting module 123 is disposed on the second moving module 122, and the adsorption element is disposed on the first lifting module 123 with its working end facing the insulating strip. Furthermore, the first moving module 121 extends along the length of the device, preferably consisting of two parallel slide rails and a guide post extending in the same direction between the two slide rails. A main mounting frame is provided on the first moving module 121, and the main mounting frame moves along the first moving module 121. A second moving module 122 extending along the width of the device is provided on the upper surface of the first moving module 121. A secondary mounting frame is provided on the second moving module 122, and the secondary mounting frame moves along the second moving module 122. A first lifting module 123 extending along the height of the device is provided on the side of the secondary mounting frame, which can carry the adsorption component connected thereto for lifting and lowering. In this embodiment, the adsorption component contacts the insulating strip and moves by adsorbing the insulating strip through negative pressure, thereby realizing the working process of the adjustment component 120. Furthermore, in this embodiment, the main mounting frame, the secondary mounting frame, and the first lifting module 123 are respectively provided with power source cylinders to provide their respective movements. In other embodiments, the power source can be set as a motor or other equipment, and the adsorption component can also be set as a gripper or other device with a handling function. The present invention does not impose specific limitations.

[0034] See Figure 2 as well as Figures 5 to 7 As shown, in the adhesive application mechanism 200, the lifting component 210 is located below the adhesive application component 220. When the adjusting component 120 and the transmission mechanism 300 respectively transport the battery cell and the insulating strip to the processing position, the lifting component 210 can rise and the adhesive application component 220 can fall, thereby achieving mutual contact and compression between the two to complete the adhesive application action. Specifically, the lifting mechanism includes a second lifting module 211, and a lifting platform 212 is located at the working end of the lifting module. In this embodiment, the upper surface of the lifting platform 212 is provided with a lifting plate, and a driving cylinder is provided below the lifting plate to drive its lifting and lowering. Furthermore, a limiting member is provided on the outer periphery of the lifting plate to block the carrying fixture 320 so as to limit the movement distance of the carrying fixture 320, thereby ensuring that it can be lifted by the lifting assembly. At the contact part between the lifting plate and the carrying fixture 320, there is also a plug-in block (not shown in the figure) that is perpendicular to its upper surface. It can be inserted into the carrying fixture 320 to keep the carrying fixture 320 in a stable state during the lifting process, thereby improving the processing stability and product yield of the equipment.

[0035] See Figure 5As shown, the adhesive application assembly 220 includes a third moving module 221 extending along the transmission direction of the insulating strip, a fourth moving module 222 located in the same horizontal plane as the third moving module 221 and arranged perpendicularly to it, and a third lifting module 223 that moves up and down along the height direction of the device. The fourth moving module 222 is mounted on the third moving module 221, and the third lifting module 223 is mounted on the fourth moving module 222. An extruder 224 is connected to the working end of the third lifting module 223 and faces the insulating strip. Further, the third moving module 221 is arranged parallel to the first moving module 121, and the fourth moving module 222 is arranged parallel to the second moving module 122. A mounting bracket that can move along its extension direction is provided on the third moving module 221. The third lifting module 223 extending along the height direction of the device is located inside the mounting bracket. The extruder 224 is connected to the third lifting module 223 and can move synchronously with the third lifting module 223. In this embodiment, after the insulating strip and the battery cell 500 to be glued are evenly delivered to the processing point, the lifting platform 212 rises while the extruder 224 descends to minimize the glue application time. In other embodiments, the lifting platform 212 and the extruder 224 can also be configured to work in a mode where one moves and the other remains stationary.

[0036] See Figure 6 As shown, the pressurized stationary mechanism 225 includes a floating head 2251 and a buffer 2252. The floating head 2251 is connected to the pressing member 224 through the buffer 2252 and moves synchronously with the pressing member 224. In this embodiment, two sets of pressurizing and stationary mechanisms 225 are provided along the width direction of the device. Further, each set of pressurizing and stationary mechanisms 225 includes two horizontally spaced buffers 2252 and two floating heads 2251. Furthermore, the buffers 2252 and their corresponding floating heads 2251 are connected sequentially from top to bottom along the height direction of the device. When the adhesive application component 220 contacts and presses against the lifting component 210, the pressurizing and stationary mechanism 225 can pause after contact and continue pressing after stabilization, thereby realizing the process of pre-pressing and then pressing. This operation can greatly improve the flatness of the adhesive application of the device, avoid the generation of air bubbles and wrinkles during adhesive application, and greatly improve the adhesive application efficiency and product yield. Similarly, the present invention does not limit the specific number and installation position of the floating heads 2251 and the corresponding buffers 2252.

[0037] See Figure 7As shown, the transmission mechanism 300 also includes a speed-multiplying line 310 extending in a direction different from the transmission direction of the insulating strip and passing through the top of the lifting platform 212. The carrying fixture 320 moves along the speed-multiplying line 310. In this embodiment, the speed-multiplying line 310 extends along the width direction of the device, and the carrying fixture 320 can move along the speed-multiplying line 310. Specifically, in this embodiment, a through hole that mates with the plug-in block is provided at the bottom of a carrying fixture 320, and four battery cell positions 321 are arranged at intervals on its upper surface. This enables the simultaneous transport of four battery cells 500 and the simultaneous application of adhesive to four battery cells 500 in conjunction with the adhesive application assembly 220. In other embodiments, multiple carrying fixtures 320 can be set on the speed-multiplying line 310 to achieve uninterrupted loading and unloading and further improve the processing effect. Other numbers of battery cell positions 321 can also be provided on any carrying fixture 320. This invention does not impose specific limitations.

[0038] The following describes the processing procedure of the battery cell insulation strip adhesive application equipment in this embodiment:

[0039] In use, the glue supply mechanism 100 transports insulating glue into the processing space through the glue application component 110 and the adjustment component 120. The entire process takes about 15 seconds. At the same time, the transmission mechanism 300 continuously delivers the battery cells 500 to be glued into the processing space through the bearing fixture 320. The timing of this delivery is coordinated with the glue supply time.

[0040] When the supporting fixture 320 moves above the lifting platform 212, the lifting platform 212 rises, and the adhesive application assembly 220 presses down the prepared insulation strip and uses the pressure-setting mechanism 225 to achieve high-precision bonding by adopting a pre-pressing and then extrusion working mode. Specifically, the processing time of the pressure-setting mechanism does not exceed 5 seconds, and the overall adhesive application process does not exceed 11.5 seconds. The battery cell 500 with the insulation strip applied returns to the speed-multiplying line 310 and is unloaded. This completes one full adhesive application process for the battery cell 500 insulation strip. The total time of the entire process can be kept within 26.5 seconds. After that, all components return to their initial positions to wait for the next adhesive application process.

[0041] In summary, the battery cell insulation strip adhesive application equipment of the present invention adjusts the position of the insulation strip through the adhesive supply mechanism 100, and then completes the adhesive application through the cooperation of the extrusion member 224 and the lifting platform 212 in the adhesive application mechanism 200. At the same time, the battery cell 500 to be adhesiveped is continuously transported to the adhesive application mechanism 200 through the transmission mechanism 300. This achieves fully automated, efficient and precise adhesive application operation. Most importantly, the pressure-pressurizing and stationary mechanism 225 in this equipment and its limitation on the extrusion speed can overcome the problems of low processing efficiency, poor compatibility, complex operation and low adhesive application quality in the prior art. It is a new type of battery cell insulation strip adhesive application equipment with broad application prospects.
