[0026] Embodiment 1

[0027] See also Figure 1 A multi-electrode arrangement glue-bonding equipment comprises: a discharge module 1, which is composed of a discharge device 11 arranged in groups, so as to realize the synchronous discharge of multiple groups of electrode metal coils; a receiving module 2, which is composed of a receiving device 12 arranged in groups, so as to realize the synchronous collection of multiple groups of electrode metal coils after glue bonding; the synchronous operation of multiple groups of discharge and receiving devices 12 significantly improves the production efficiency, shortens the production cycle, and reduces the unit cost.

[0028] Refer to 2 and 3. The unloading device 11 and the receiving device 12 both include a feeding roller 21 and a diaphragm roller 22. The feeding roller 21 and the diaphragm roller 22 are arranged on a mobile platform. The positions of the feeding roller 21 and the diaphragm roller 22 are adjusted by the mobile platform to realize the horizontal arrangement of multiple groups of pole piece metal rolls.

[0029] Specifically, the displacement of the slide plate 26 is achieved through the precise control of the telescopic cylinder 25, and then the positions of the material placement roller 21 and the diaphragm roller 22 are adjusted to ensure that multiple groups of pole piece metal rolls can be arranged horizontally and evenly, providing a stable foundation for the subsequent gluing step.

[0030] See 2 and 3. The mobile platform includes a base plate 23. A slide rail 24 and a telescopic cylinder 25 are provided on both sides of the base plate 23. The sliding direction of the slide rail 24 is parallel to the telescopic direction of the telescopic cylinder 25. A slide plate 26 is provided on the slide rail 24. The slide plate 26 is used to install the feeding roller 21 and the diaphragm roller 22. The telescopic cylinder 25 is swingably installed on the base plate 23. The output end of the telescopic cylinder 25 is swingably connected to the slide plate 26. The position of the slide plate 26 is controlled by the telescopic cylinder 25 to adjust the position of the feeding roller 21 and the diaphragm roller 22 so that multiple groups of pole piece metal rolls can be arranged horizontally. Through the cooperation of the telescopic cylinder 25 and the slide rail 24, the position of the feeding roller 21 and the diaphragm roller 22 can be fine-tuned to ensure the precise arrangement of the pole piece metal rolls and improve the accuracy and consistency of the glue sticking.

[0031] The unloading device 11 or the receiving device 12 are arranged in pairs to form a group; the mobile platform is provided with a guide roller 27, which not only guides the pole piece metal roll to be smoothly transmitted, but also the adjacently arranged guide rollers 27 help to maintain the straightness and stability of the pole piece metal roll during the transmission process, and reduce the deviation caused by mechanical vibration or friction. The guide rollers 27 on each group of the unloading device 11 and each group of the receiving device 12 are arranged adjacently; the unloading device 11 also includes a correction sensor 31, which can monitor the relative position of the pole piece metal roll in the unloading process in real time to ensure that the pole piece metal roll moves accurately along the predetermined path. Once a position deviation is detected, the correction sensor 31 will immediately send a signal to the control system.

[0032] The deflection correction sensor 31 is arranged adjacent to each group of the unloading device 11; the combination of the adjacent arrangement of the guide roller 27 and the deflection correction sensor 31 ensures the stability and straightness of the pole piece metal roll during the transmission process, creating favorable conditions for the subsequent gluing process. The deflection correction sensor 31 detects the relative position of the pole piece metal roll during unloading and feeds back to the telescopic cylinder 25; the telescopic cylinder 25 realizes the position correction of the pole piece metal roll.

[0033] Specifically, when the deviation correction sensor 31 detects the position deviation of the pole piece metal roll, the system will automatically activate the telescopic cylinder 25, and through the fine-tuning action of the telescopic cylinder 25, the position of the pole piece metal roll is corrected in real time to ensure that the pole piece metal roll can be accurately aligned in the subsequent gluing process, thereby improving the gluing quality and the consistency of the finished product. Through the linkage of the deviation correction sensor 31 and the telescopic cylinder 25, this design can effectively correct the slight deviation of the pole piece metal roll during the transmission process, ensure the accurate position of the pole piece metal roll before gluing, and lay the foundation for high-quality gluing.

[0034] Refer to 2 and 3. A tension motor 28 and a diaphragm motor 29 are also provided on the mobile platform; the tension motor 28 is used to control the rotation of the pole piece metal roll on the feeding roller 21 to control the surface tension of the pole piece metal roll; a magnetic powder clutch 281 is also provided between the tension motor 28 and the feeding roller 21; the diaphragm motor 29 is used to control the rotation of the diaphragm roller 22 to control the retraction and extension of the diaphragm during operation.

[0035] Specifically, by precisely adjusting the surface tension of the pole piece metal coil and the retraction and extension of the diaphragm, problems such as material deformation and wrinkling are effectively avoided, the quality and consistency of the tab glue are ensured, and the safety and performance of the finished battery are improved. The precise tension and diaphragm control mechanism reduces waste caused by improper material handling, reduces production costs, and improves economic benefits.

[0036] See also Figure 1 , also includes: a glue placing device, which is used to place the pole lug film roll; ensure that the film roll is in sufficient supply. A glue sticking device 33, which is used to stick the pole lug film roll on the surface of the pole piece metal roll; the glue sticking device 33 includes a pair of limiting rollers 331 arranged adjacent to each other, and the pole lug film roll and the pole piece metal roll pass through the limiting rollers 331 to achieve the bonding of the pole lug film roll and the pole piece metal roll. Also includes: a positioning block 32, which is located between the discharge module 1 and the glue placing device; the positioning block 32 is provided with a positioning groove to position the pole piece metal roll into the positioning groove. The shape and size of the positioning groove on the positioning block 32 match the edge contour of the pole piece metal roll, and can be accurately embedded in the pole piece metal roll to ensure that it is in the correct position before gluing.

[0037] Specifically, in a conventional electrode gluing process, the electrode metal roll and the electrode tab film roll are first cut, and then the electrode metal roll and the electrode tab film roll are glued. The device only cuts the pole piece metal roll, and then arranges the cut pole piece metal roll horizontally before pasting it with the uncut pole ear film roll. The advantages are: first, since the pole ear film roll does not need to be cut in advance, the material waste generated in the cutting process can be avoided, especially for longer or wider films, the material saved may be considerable; second, since the pole ear film roll does not need to be cut in advance, the material waste generated in the cutting process can be avoided, especially for longer or wider films, the material saved may be considerable; third, the cutting of the pole piece metal roll and the gluing of the pole ear film roll can be carried out simultaneously, reducing the waiting time and the intermediate processing time, thereby improving the overall production speed; fourth, the pole piece metal roll and the pole ear film roll can be aligned at one time when pasting, reducing the possibility of multiple alignments, reducing the risk of alignment errors, and helping to improve the consistency and quality of the finished product; fifth, since the pole ear film roll does not need to be cut, the demand for high-precision slitting equipment may be reduced, thereby reducing the equipment investment cost.

[0038] See also Figure 1 , also includes: a rubber shoulder cutting device 4, the rubber shoulder cutting device 4 has a first cutter, the first cutter is used to cut off the excess pole ear glue of the outermost pole piece metal roll; to make it symmetrical on the left and right. Also includes: a slitting device 6, the slitting device 6 includes a second cutter, the second cutter is used to cut multiple groups of pole piece metal rolls with pole ear glue pasted, to facilitate subsequent high-temperature heating of current. Precision cutting device 7; the precision cutting device 7 precision cutting device 7 includes a third cutter, the third cutter is used to cut off the excess pole ear glue on both sides of the pole piece metal roll after slitting. Specifically, the rubber shoulder cutting device 4, the slitting device 6 and the precision cutting device 7 are used for slitting the pole piece roll after pasting and removing the excess pole ear glue; not only further improve the appearance quality of the finished product, but also optimize the electrical performance of the pole ear, so that the battery shows better stability and safety during the charging and discharging process.

[0039] See also Figure 1, the exhaust device 5, by effectively exhausting the air, ensures that the colloid and the metal strip form a close contact without gaps, thereby significantly improving the strength and stability of the bonding. The exhaust device 5 includes a heating roller 51, which is used to heat the pasted pole ear glue roll and the pole piece metal roll, and squeeze out the air between the pole ear glue roll and the pole piece metal roll. The exhaust device 5 is located on both sides of the rubber shoulder cutting device 4, and is respectively a first exhaust device 5 and a second exhaust device 5; wherein the first exhaust device 5 heats the fixed pole ear glue and metal strip through the heating roller 51, exhausts the air between the metal strip and the pole ear glue, enhances the bonding effect, and makes the bonding firm; the second exhaust device 5 heats the fixed pole ear glue and metal strip through the heating roller 51, maintains the temperature of the metal strip, and makes the metal strip and the pole ear glue bond more firmly.

[0040] Specifically, the first exhaust device 5 is located on one side of the rubber shoulder cutting device 4, and its main task is to heat the composite material through the heating roller 51 after the pole piece metal roll and the pole ear film roll are initially bonded. The purpose of heating is to soften the pole ear glue, making it more fluid and easier to fill the gap between the metal strip and the film roll. At the same time, the pressure of the heating roller 51 can effectively squeeze out the air trapped between the two, avoid the formation of bubbles, and thus significantly improve the tightness of the bonding. This process is crucial to enhancing the initial bonding effect and lays a solid foundation for the subsequent bonding stability. The second exhaust device 5 is located on the other side of the rubber shoulder cutting device 4. Its function is to continue to maintain the temperature of the metal strip through the heating roller 51 after the initial bonding, prolong the flow time of the pole ear glue, and further promote the deep fusion of the glue and the metal strip. Continuous heating helps the flow and diffusion of the colloid before it is completely cured, so that the pole ear glue can be more evenly distributed on the metal strip, enhancing the uniformity and strength of the bonding. In addition, the heating roller 51 of the second exhaust device 5 can squeeze out any remaining air again to ensure the smoothness of the bonding surface and prevent bonding failure due to stress concentration in subsequent use.

[0041] See also Figure 4, and also includes: a hot melt device 8 and a cold press device 9 located between the slitting device 6 and the fine cutting device 7; the hot melt device 8 includes a negative conductive block 81 and a positive conductive block 82 through which the pole piece metal coil passes in sequence, and the negative conductive block 81 and the positive conductive block 82 perform single-group energization heating on the slit pole piece metal coil to enhance the adhesive effect. A temperature sensor is provided between the negative conductive block 81 and the positive conductive block 82 to detect the surface temperature of the pole piece metal coil after heating; a temperature sensor is provided to monitor the surface temperature of the pole piece metal coil after heating in real time. It is crucial to prevent overheating or insufficient heating, and helps to maintain the consistency and stability of the adhesive effect. The cold pressing device 9 includes a pressing table 92 and a pressing plate 93, and the heights of the pressing table 92 and the pressing plate 93 are controlled by a control cylinder; the cold pressing device 9 is located on both sides of the positive electrode conductive block 82, and is respectively a first cold pressing device 9 and a second cold pressing device 9; wherein the first cold pressing device 9 is used to quickly cool and shape the hot-melted tab glue and metal strip, so as to meet the bonding and appearance standards of the product; the second cold pressing device 9 performs secondary cooling on the metal strip and tab glue to maintain the performance of the tab.

[0042] Specifically, the first cold pressing device 9 is located on one side of the positive electrode conductive block 82, and is mainly used to quickly cool the pole ear glue and metal strip that have just been hot-melted, so that they can be quickly shaped to meet the bonding and appearance standards of the product. This process is crucial for fixing the position of the pole ear glue and preventing it from being displaced or deformed in subsequent processing. The second cold pressing device 9 is located on the other side of the positive electrode conductive block 82, and performs secondary cooling on the metal strip and the pole ear glue to ensure that the performance of the pole ear glue is maintained for a long time. Secondary cooling not only helps to further consolidate the bonding effect, but also improves the mechanical properties of the pole ear, such as folding resistance, tensile strength, etc., thereby improving the overall quality and reliability of the finished battery. Furthermore, the bonding of the metal strip and the film in the device is carried out by current heating, which can not only achieve almost instantaneous heating and cooling, but also has a faster response speed than the traditional heat conduction heating method; it can also achieve very precise control of the heating temperature by accurately controlling the current size and time. Moreover, the heat generated when the current passes through the metal strip is evenly distributed. In battery manufacturing, uniform heating can ensure the consistency of bonding between the pole piece metal roll and the pole ear glue.

[0043] Embodiment 2

[0044] This embodiment adopts a multi-electrode arrangement glue sticking device in the first embodiment. The following is a description of the principle of the device:

[0045] Working principle of a multi-electrode arrangement glue sticking equipment:

[0046] After the equipment is started, multiple groups of electrode metal coils are released through the feeding roller 21 of the discharge module 1, positioned by the positioning block 32, and bonded with the electrode ear glue coils released from the glue release device through the limiting roller 331 in the glue bonding device 33. During the bonding process, the first cutter of the glue shoulder cutting device 4 cuts off excess electrode ear glue, and the heating roller 51 of the exhaust device 5 heats and exhausts air to improve the bonding quality. Subsequently, the second cutter of the slitting device 6 separates the multiple groups of electrode metal coils after gluing, and the third cutter of the fine cutting device 7 removes excess electrode ear glue. Finally, the hot melt device 8 enhances the bonding effect by heating with electricity, and the cold pressing device 9 cools and presses to ensure the bonding strength and quality consistency of the final product.

[0047] The technical effects of the present invention are mainly reflected in the following aspects: The equipment realizes the synchronous discharge and collection of multiple groups of pole piece metal coils through the innovative design of the multi-ear arrangement glue sticking equipment, greatly improving the production efficiency. Compared with the traditional single discharge and collection method, the present invention can process multiple pole pieces at the same time, significantly shorten the production cycle, and meet the needs of large-scale battery manufacturing. The use of electric current heating to paste the metal strip and the glue roll can not only achieve almost instantaneous heating and cooling, but also has a faster response speed than the traditional heat conduction heating method; it can also achieve very precise control of the heating temperature by precisely controlling the current size and time. Moreover, the heat generated when the current passes through the metal strip is evenly distributed. In battery manufacturing, uniform heating can ensure the consistency of the bonding between the pole piece metal coil and the pole ear glue.

[0048] In addition, as common knowledge in the industry, the rubber shoulder cutting device 4, the slitting device 6, and the precision cutting device 7 mentioned above are common knowledge, so their principles and structures will not be described in detail.
