Description

Technical Field

[0001] This invention relates to the field of battery technology, and in particular to an electrode assembly housing device. Background Technology

[0002] Since its development, lithium-ion batteries have begun to be used in electric vehicles, energy storage and other applications. Among them, blade batteries have advantages such as high energy density and high heat dissipation efficiency, which have brought about a new revolution in the development of lithium-ion battery technology.

[0003] Currently, the trend of gradually thinning the casing and increasing the number of electrode stack layers in blade batteries makes the assembly of electrode stacks and casings more difficult. Specifically, when the electrode stacks are installed into the casing, scratches often occur between the electrode stacks and the casing, resulting in scratches on the electrode stacks. This not only reduces the pass rate of battery products but also poses certain battery safety hazards.

[0004] Therefore, there is an urgent need to propose a pole assembly housing device to solve the above-mentioned technical problems. Summary of the Invention

The portion of the housing closer to the first positioning part can be embedded in the first through groove, and the portion of the housing closer to the second positioning part can be embedded in the second through groove.

[0022] Beneficial effects:

[0023] The electrode assembly housing device provided by this invention includes a Mylar film roll mounted on a frame. A film feeding mechanism clamps a portion of the Mylar film on the Mylar film roll and pulls the Mylar film through a first opening and a second opening into the housing. A film pulling mechanism clamps the Mylar film at the second opening and pulls it to cover the end face of the electrode assembly. An electrode assembly conveying mechanism clamps the electrode assembly and feeds the electrode assembly with the Mylar film covering its end face into the housing through the second opening. Because the Mylar film covers the end face of the electrode assembly, it effectively separates the electrode assembly from the housing when the electrode assembly is installed, preventing scratches between the electrode assembly and the housing, thus avoiding damage to the electrode assembly. This device improves the battery product qualification rate and enhances battery product safety. Attached Figure Description

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0041] This embodiment provides an electrode assembly insertion device for inserting electrodes into a housing. When inserting the electrodes into the housing, it can avoid the problem of scratching between the electrode assembly and the housing, thus improving the battery product qualification rate and the battery product safety.

[0042] Specifically, such as Figure 1 and Figure 2As shown, the housing 20 has a first opening 21 and a second opening 22 arranged opposite to each other. The electrode assembly housing device includes a frame, a housing positioning mechanism 200, a film feeding mechanism 300, a film pulling mechanism 400, and an electrode assembly conveying mechanism 500. A Mylar film roll 100 is provided on the frame. The housing positioning mechanism 200 is used to fix the housing 20. The film feeding mechanism 300 is movably mounted on the frame. The film feeding mechanism 300 is used to clamp a portion of the Mylar film on the Mylar film roll 100 and pull the Mylar film through the first opening 21 and the second opening 22 to pass through the housing 20. The film pulling mechanism 400 is movably mounted on the frame. The film pulling mechanism 400 is used to clamp the Mylar film at the second opening 22 and pull the Mylar film to cover the end face of the electrode assembly 10. The electrode assembly conveying mechanism 500 is movably mounted on the frame. The electrode assembly conveying mechanism 500 is used to clamp the electrode assembly 10 and send the electrode assembly 10 with the end face covered by the Mylar film into the housing 20 through the second opening 22.

[0043] When assembling the electrode assembly 10 and the housing 20, the film feeding mechanism 300 clamps a portion of the Mylar film on the Mylar film roll 100 and pulls the clamped Mylar film through the first opening 21 and the second opening 22 sequentially into the housing 20. At the second opening 22, the film pulling mechanism 400 clamps the Mylar film on the film feeding mechanism 300 and pulls the Mylar film to cover the end face of the electrode assembly 10. Then, the electrode assembly conveying mechanism 500 feeds the electrode assembly 10 with the Mylar film covering its end face into the housing 20 through the second opening 22. Simultaneously, as the electrode assembly 10 continuously enters the housing 20, the film feeding mechanism 300 passes through the second opening 22 to the first opening 21 and exits the housing 20 to provide clearance for the electrode assembly 10. This electrode assembly housing entry device is achieved by setting a film feeding machine. The structure 300 and the film-pulling mechanism 400 use a housing 20 for fixing and feeding the electrode assembly 10 into the housing 20. A Mylar film is covered on the end face of the electrode assembly 10. When the electrode assembly 10 is installed into the housing 20, the Mylar film separates the electrode assembly 10 from the housing 20, avoiding the problem of the electrode assembly 10 rubbing against the housing 20 and thus preventing the electrode assembly 10 from being scratched. Furthermore, due to the high flexibility of the Mylar film, covering the end face of the electrode assembly 10 can provide a certain buffering effect against collisions between the electrode assembly 10 and the housing 20, thereby providing a certain degree of protection for the electrode assembly 10. This has the effect of improving the qualification rate and safety of battery products.

[0044] Furthermore, such as Figure 2 As shown, there are two film-pulling mechanisms 400 and two Mylar film rolls 100, which correspond to each other. The two film-pulling mechanisms 400 are respectively set above the electrode group 10 and below the electrode group 10, so as to achieve the effect of covering the upper and lower end surfaces of the electrode group 10 with Mylar film. Thus, the upper and lower end surfaces of the electrode group 10 can be separated from the housing 20 by the Mylar film, avoiding the friction between the upper and lower end surfaces of the electrode group 10 and the housing 20.

[0045] Furthermore, to achieve the clamping and conveying of the Mylar film on the two Mylar film rolls 100 by the film feeding mechanism 300, such as... Figures 2 to 4 As shown, the film feeding mechanism 300 includes a film feeding mounting frame 310, two film feeding drive devices 320, a first clamping plate 330, and two second clamping plates 340. The fixed ends of the first clamping plate 330 and the two film feeding drive devices 320 are all fixed to the film feeding mounting frame 310, and the first clamping plate 330 is located between the two film feeding drive devices 320. The driving ends of the two film feeding drive devices 320 are respectively connected to the two second clamping plates 340. Under the drive of the two film feeding drive devices 320, the two second clamping plates 340... The two second clamping plates 340 can move towards and away from the first clamping plate 330, respectively, thereby cooperating with the first clamping plate 330 to clamp the Mylar film on the two Mylar film rolls 100. The film feeding mounting bracket 310 is movably mounted on the frame, so that the end of the first clamping plate 330 near the film pulling mechanism 400 and the ends of the two second clamping plates 340 near the film pulling mechanism 400 can sequentially pass through the first opening 21 and the second opening 22 into the housing 20, and can exit the housing 20 from the second opening 22 to the first opening 21. Optionally, the above-mentioned film feeding drive device 320 can be a reciprocating cylinder or a reciprocating screw module, etc. Preferably, such as Figures 2 to 4 As shown, both second clamping plates 340 are provided with stepped structures 331, and the stepped structures 331 on both second clamping plates 340 are set towards the first clamping plate 330. When the second clamping plate 340 and the first clamping plate 330 cooperate to clamp the Mylar membrane, the step surface and the step vertical surface of the stepped structure 331 can increase the contact pressure between the second clamping plate 340 and the Mylar membrane, thereby improving the stability and reliability of the clamping of the Mylar membrane by the second clamping plate 340 and the first clamping plate 330. When the film feeding mechanism 300 clamps the Mylar membrane and pulls the Mylar membrane through the shell 20, the role of the stepped structure 331 is particularly prominent, which can ensure that the film feeding mechanism 300 always keeps the Mylar membrane clamped during the process of passing through the shell 20.

[0046] Optionally, the drive ends of the two film feeding drive devices 320 are respectively connected to the two second clamping plates 340 by hexagonal screws, or they can be fixed by welding or other methods.

[0047] Optionally, such as Figures 2 to 5As shown, the film-pulling mechanism 400 includes a heat-fusion assembly for heat-fusioning the Mylar film covering the end face of the electrode assembly 10 onto the end face of the electrode assembly 10. The electrode assembly housing device also includes a film-cutting mechanism 600 located at the first opening 21. The film-cutting mechanism 600 is used to cut the Mylar film between the film-feeding mechanism 300 and the electrode assembly 10, so that the electrode assembly housing device not only completes the assembly of the electrode assembly 10 and the housing 20, but also completes the work of covering the electrode assembly 10 with an insulating film. Specifically, the Mylar film is covered on the end face of the electrode assembly 10 under the action of the film-pulling mechanism 400, and under the action of the heat-fusion assembly, the film covering the electrode assembly is... The Mylar film on the end face of electrode assembly 10 is heat-fused to the end face of electrode assembly 10. Under the action of electrode assembly conveying mechanism 500, electrode assembly 10 and the Mylar film heat-fused to its end face enter housing 20 through the second opening 22 of housing 20. At this time, the Mylar film is not disconnected from the Mylar film roll 100. After electrode assembly 10 is installed into housing 20, film feeding mechanism 300 also exits housing 20. Film cutting mechanism 600 set at the first opening 21 cuts the Mylar film between electrode assembly 10 and film feeding mechanism 300, so that the Mylar film on the end face of electrode assembly 10 is disconnected from the Mylar film roll 100, while the Mylar film heat-fused to the end face of electrode assembly 10 is fixed to electrode assembly 10.

[0048] Furthermore, such as Figures 2 to 5 As shown, there are two film cutting mechanisms 600. The two film cutting mechanisms 600 correspond to the Mylar film on the two Mylar film rolls 100 respectively, and cut the Mylar film on the upper and lower ends of the electrode group 10 respectively.

[0049] Optionally, such as Figures 2 to 5 As shown, the electrode assembly housing device also includes two winding and unwinding machines. Two Mylar film rolls 100 are respectively mounted on the two winding and unwinding machines. When the film feeding mechanism 300 clamps the two Mylar films and moves from the first opening 21 to the second opening 22, the winding and unwinding machines rotate forward to release the Mylar film on the Mylar film roll 100. When the electrode assembly 10 enters the housing 20 through the second opening 22, since the Mylar film covering the end face of the electrode assembly 10 has not yet been disconnected from the Mylar film roll 100, when the electrode assembly 10 is installed into the housing 20, the winding and unwinding machines reverse to retract the Mylar film between the end face of the electrode assembly 10 and the Mylar film roll 100, so that the Mylar film between the electrode assembly 10 and the Mylar film roll 100 can always be in a taut state, which is convenient for the film feeding mechanism 300 to clamp the Mylar film next time.

[0050] Optionally, such as Figures 2 to 6As shown, the film cutting mechanism 600 includes a film cutting mounting plate 610, a film cutting drive device 620, a film cutting connecting plate 630, a cutting electric heating device 641, and a metal wire 642. The fixed end of the film cutting drive device 620 is fixed on the film cutting mounting plate 610, and the driving end of the film cutting drive device 620 is connected to the film cutting connecting plate 630. The cutting electric heating device 641 is connected to the film cutting connecting plate 630 through a connector, and the metal wire 642 is wound or fastened to the cutting electric heating device. In device 641, after the cutting electric heating device 641 is energized, the temperature of the metal wire 642 rises. Driven by the film cutting drive device 620, the film cutting connecting plate 630 moves the cutting electric heating device 641 and the metal wire 642 closer to the Mylar film until the metal wire 642 heats and breaks the Mylar film. Then, driven by the film cutting drive device 620, the film cutting connecting plate 630 moves the cutting electric heating device 641 and the metal wire 642 away from the Mylar film, thereby achieving the cutting of the Mylar film. Optionally, the aforementioned film cutting drive device 620 can be a reciprocating cylinder, a lead screw module, or other drive device. Optionally, the aforementioned metal wire 642 can be made of materials such as nickel-chromium heating alloy or iron-chromium-aluminum alloy. It is understood that in other embodiments, the film cutting mechanism 600 can be other structural forms capable of cutting Mylar film, for example, providing a rotary cylinder and a cutter connected to the drive end of the rotary cylinder, using the cutter to cut the Mylar film, etc. Optionally, the connector and the cutting connecting plate 630, and the connector and the cutting electric heating device 641, can be connected by means of hex screws or welding. Optionally, the metal wire 642 can be wound around the cutting electric heating device 641 to increase the electrical connection area between the two.

[0051] Optionally, such as Figures 2 to 6As shown, the hot-melt assembly includes a hot-melt electric heating device (not shown), a hot-melt metal part 411, and a hot-melt driving device 412. The hot-melt metal part 411 can be block-shaped, strip-shaped, or plate-shaped. The hot-melt electric heating device is electrically connected to the hot-melt metal part 411. The film-stretching mechanism 400 also includes a film-stretching mounting plate 420. The fixed end of the hot-melt driving device 412 is fixed on the film-stretching mounting plate 420. The driving end of the hot-melt driving device 412 is provided with a film-stretching connecting plate 413. The hot-melt metal and the film-stretching connecting plate 413 are connected by a connector. After the hot-melt electric heating device is powered on, the temperature of the hot-melt metal part 411 rises. Under the drive of the hot-melt driving device 412, the film-stretching connecting plate 413 drives the hot-melt metal part 411 to approach the electrode group 10, so as to hot-melt the Mylar film covering the end face of the electrode group 10 onto the end face of the electrode group 10, thereby fixing the Mylar film on the end face of the electrode group 10. It is understandable that the area of ​​the Mylar film melted onto the end face of the electrode assembly 10 is determined by the cross-sectional area of ​​the melted metal portion 411. If the cross-sectional area of ​​the melted metal portion 411 is small, the area of ​​the Mylar film melted onto the end face of the electrode assembly 10 is small; if the cross-sectional area of ​​the melted metal portion 411 is large, the area of ​​the Mylar film melted onto the end face of the electrode assembly 10 is large, and the area of ​​the Mylar film melted onto the end face of the electrode assembly 10 can even be equal to the area of ​​the end face of the electrode assembly 10. Optionally, the melt-driving device 412 can be a reciprocating cylinder, a lead screw module, or other driving device. Further, as mentioned above, the two film-drawing mechanisms 400 are respectively arranged above and below the electrode assembly 10, and the melted metal portions 411 in the two film-drawing mechanisms 400 are symmetrically arranged relative to the electrode assembly 10, so that the positions of the Mylar films melted onto the upper and lower end faces of the electrode assembly 10 are symmetrical. Optionally, the membrane connecting plate 413 and the connector, as well as the connector and the hot-melt metal part 411, can be connected by means of hex screws or welding.

[0052] Optionally, such as Figures 2 to 6 As shown, the film-pulling mechanism 400 also includes a film-pulling gripper assembly 431, which is disposed on the film-pulling mounting plate 420. The film-pulling gripper assembly 431 can clamp the Mylar film at the second opening 22. The film-pulling mounting plate 420 is movably mounted on the frame to drive the film-pulling gripper assembly 431 that clamps the Mylar film to move and cover the Mylar film on the end face of the electrode group 10, thereby realizing the effect of the film-pulling mechanism 400 clamping and pulling the Mylar film.

[0053] Preferably, such as Figures 2 to 6As shown, the film-pulling mechanism 400 also includes a film-pulling claw drive device 432. The fixed end of the film-pulling claw drive device 432 is fixed on the film-pulling mounting plate 420, and the drive end of the film-pulling claw drive device 432 is connected to the film-pulling claw assembly 431. As mentioned above, the electrode assembly housing device has two film-pulling mechanisms 400. Therefore, under the respective drive of the two film-pulling claw drive devices 432, the distance between the two film-pulling claw assemblies 431 can be adjusted, thereby achieving the effect of adjusting the distance between the film-pulling membranes held by the two film-pulling claw assemblies 431. Optionally, the film-pulling claw drive device 432 can be a reciprocating cylinder, a lead screw module, or other drive device. Optionally, the drive end of the film-pulling claw drive device 432 and the film-pulling claw assembly 431 can be connected by hexagonal screws or welding.

[0054] Optionally, such as Figures 2 to 7 As shown, the housing positioning mechanism 200 includes a positioning part and a first suction cup 231. The positioning part is used to fix the housing 20, and the first suction cup 231 can adhere to the end face of the housing 20 and expand the housing 20, that is, increase the cross-sectional area of ​​the first opening 21 and the second opening 22, so as to facilitate the entry of the electrode assembly 10 into the housing 20 and avoid scratching between the electrode assembly 10 and the housing 20. It should be noted that the housing 20 can be made of aluminum, steel or non-metallic materials, and no specific limitation is made here.

[0055] Furthermore, such as Figures 2 to 7 As shown, the positioning part includes a first positioning part 210 and a second positioning part 220. The first positioning part 210 and the second positioning part 220 are respectively disposed on opposite sides of the housing 20. The first positioning part 210 is provided with a first through groove, and the second positioning part 220 is provided with a second through groove. The length of the first through groove and the length of the second through groove are both equal to the length of the housing 20. The openings of the first through groove and the openings of the second through groove are opposite to each other and spaced apart. The portion of the housing 20 near the first positioning part 210 can be embedded in the first through groove, and the portion of the housing 20 near the second positioning part 220 can be embedded in the second through groove. The first suction cup 231 is located at the edge of the first through groove and the second positioning part 220. Between the edges of the two through slots, when the first suction cup 231 expands the housing 20, the two sides of the housing 20 are prone to warping, which can cause the housing 20 to deform. In this embodiment, the part of the housing 20 near the first positioning part 210 is embedded in the first through slot, and the part of the housing 20 near the second positioning part 220 is embedded in the second through slot. This achieves the limitation of the two sides of the housing 20, avoids the problem of the two sides of the housing 20 warping when the first suction cup 231 expands the housing 20, reduces the probability of the housing 20 deforming, and makes the overall structure of the housing 20 more consistent, thereby improving the yield of the battery product.

[0056] Preferably, such as Figures 2 to 7As shown, the first positioning part 210 includes a first positioning block 211 and a second positioning block 212. The first positioning block 211 has a first notch on its edge, and the second positioning block 212 has a second notch on its edge. The second positioning part 220 includes a third positioning block 221 and a fourth positioning block 222. The third positioning block 221 has a third notch on its edge, and the fourth positioning block 222 has a fourth notch on its edge. The housing positioning mechanism 200 also includes a first positioning drive device (not shown in the figure). The first positioning drive device can drive the second positioning block 212 to approach the first positioning block 211, so that the first notch and the second notch cooperate to form a first through groove. The first positioning drive device can also drive the fourth positioning block 222 to approach the third positioning block 221, so that the third notch and the fourth notch cooperate to form a second through groove. The first suction cup 231 is located between the second positioning block 212 and the fourth positioning block 222. Optionally, the above-mentioned first positioning drive device can be a reciprocating cylinder, a lead screw module, or other drive device.

[0057] Furthermore, such as Figures 2 to 7 As shown, the housing positioning mechanism 200 also includes a housing positioning mounting plate 250 and four connecting posts 260. One end of two of the four connecting posts 260 is fixed to both ends of the second positioning block 212, and one end of the other two connecting posts 260 is fixed to both ends of the fourth positioning block 222. The other ends of the four connecting posts 260 are fixedly connected to the housing positioning mounting plate 250. The driving end of the first positioning driving device is connected to the housing positioning mounting plate 250, thereby realizing that under the drive of the first positioning driving device, the second positioning block 212 moves toward the first positioning block 211, and the fourth positioning block 222 moves toward the third positioning block 221. Optionally, in this embodiment, the housing positioning mounting plate 250, the second positioning block 212, and the fourth positioning block 222 are all provided with threaded holes, and both ends of the connecting posts 260 are provided with external threads. The threaded holes and external threads are threaded together, thereby realizing the connection between the housing positioning mounting plate 250 and the second positioning block 212 and the fourth positioning block 222 through the connecting posts 260. Of course, in other embodiments, the fixed connection can also be achieved by welding or other methods.

[0058] Optionally, such as Figures 2 to 7As shown, the housing positioning mechanism 200 also includes a suction rod 232 and a spring 233. One end of the suction rod 232 is connected to the first suction cup 231, and the other end is fixedly connected to the housing positioning mounting plate 250. The spring 233 is set on the suction rod 232. Pressing the first suction cup 231 causes the first suction cup 231 to adhere to the end face of the housing 20. Then, pulling the spring 233 causes the suction rod 232 to drive the first suction cup 231 to lift the housing 20, thereby expanding the housing 20. Furthermore, since the spring 233 has a certain elasticity, the way the first suction cup 231 is pulled to expand the housing 20 can be buffered and finely adjusted in terms of the expansion size of the housing 20, avoiding the problem of local breakage of the housing 20 during the expansion process. Optionally, the outer wall of the other end of the suction rod 232 is provided with an external thread, and the housing positioning mounting plate 250 is provided with a threaded hole. The external thread and the threaded hole are threadedly engaged to achieve a fixed connection between the suction rod 232 and the housing positioning mounting plate 250. Of course, the suction rod 232 and the housing positioning mounting plate 250 can also be fixed by welding or bolting or other methods. It is understood that in other embodiments, the first suction cup 231 can be connected to the suction air source on one side of the end face of the housing 20 through a suction pipe. Under the action of the suction air source, the first suction cup 231 is adsorbed on the end face of the housing 20 and the housing 20 is expanded. As long as the first suction cup 231 can be used to expand the housing 20, it is acceptable. No specific limitation is made here.

[0059] Preferably, such as Figures 2 to 7 As shown, there are multiple springs 233, suction rods 232 and first suction cups 231 arranged in groups. Multiple first suction cups 231 are evenly spaced along the length of the housing 20 to improve the magnitude and uniformity of the adsorption force applied to the housing 20, so that the housing 20 can expand more evenly and stably.

[0060] Preferably, such as Figures 2 to 8 As shown, the electrode assembly housing device also includes a housing conveying mechanism 700. The housing conveying mechanism 700 includes a housing conveying plate 710 and a housing conveying drive device 720. The housing 20 can be disposed on the housing conveying plate 710. The drive end of the housing conveying drive device 720 is connected to the housing conveying plate 710 to drive the housing conveying plate 710 to send the housing 20 between the first positioning block 211 and the third positioning block 221, thereby realizing automatic feeding of the housing 20, eliminating manual feeding, and improving production efficiency. Of course, after the electrode assembly 10 and the housing 20 are assembled, the housing conveying mechanism 700 can also realize the unloading process. At this time, the housing conveying drive device 720 drives in reverse to drive the housing conveying plate 710 to move in the opposite direction. In this embodiment, the housing conveying drive device 720 is a lead screw module. Of course, in other embodiments, the housing conveying drive device 720 can also be a reciprocating cylinder or other drive devices.

[0061] Preferably, such as Figures 2 to 8 As shown, the housing conveying mechanism 700 also includes two guide pillars 740, which are located on both sides of the housing conveying drive device 720. The driving ends of the two guide pillars 740 are connected to the housing conveying plate 710. When the housing conveying drive device 720 drives the housing conveying plate 710 to move, the guide pillars 740 can provide guidance and support for the housing conveying plate 710, making the loading and unloading process of the housing 20 more stable.

[0062] Furthermore, such as Figures 2 to 8 As shown, the housing conveying mechanism 700 further includes a second suction cup 730, which is disposed on the housing conveying plate 710. The second suction cup 730 adsorbs one end face of the housing 20 and is connected to the suction air source via a connecting pipe, allowing the second suction cup 730 to adsorb the housing 20 onto the housing conveying plate 710, thereby improving the stability of the housing conveying mechanism 700 in conveying the housing 20. Preferably, there are multiple second suction cups 730, which are evenly distributed along the length of the housing conveying plate 710, improving the uniformity of fixing the housing 20.

[0063] Optionally, such as Figures 2 to 8As shown, the housing positioning mechanism 200 also includes two second positioning drive devices 240. The drive ends of the two second positioning drive devices 240 are respectively connected to the first positioning block 211 and the third positioning block 221 to drive the first positioning block 211 and the third positioning block 221 to adjust the position of the housing 20 on the housing conveying plate 710, thereby improving the accuracy of the relative position between the housing 20 and the pole assembly 10, facilitating the installation of the pole assembly 10 into the housing 20, and avoiding the problem of the pole assembly 10 rubbing against the housing 20 due to the low accuracy of their relative position. Optionally, the second positioning drive device 240 can be a reciprocating cylinder, a lead screw module, or other drive device. When the housing 20 is loaded, it is first placed on the housing conveying plate 710. Driven by the housing conveying drive device 720, the housing conveying plate 710 conveys the housing 20 between the first positioning block 211 and the third positioning block 221. Then, the two second positioning drive devices 240 drive the first positioning block 211 and the third positioning block 221 respectively, so that the first positioning block 211 and the third positioning block 221 move closer to the housing 20. Then, driven by the first positioning drive device, the second positioning block 212 moves toward the first positioning block 211 and the fourth positioning block 222 moves toward the third positioning block 221, so that the first notch and the second notch cooperate to form The first through groove, the third notch, and the fourth notch cooperate to form the second through groove, and a portion of the housing 20 is embedded in the first and second through grooves to fix the housing 20 by the housing positioning mechanism 200. The first suction cup 231 is adsorbed onto the end face of the housing 20, and the spring 233 is pulled, causing the suction rod 232 to drive the first suction cup 231 to lift the housing 20, thereby expanding the housing 20. At this time, since the two sides of the housing 20 are respectively embedded in the first and second through grooves, the first and second through grooves are used to limit the two sides of the housing 20, thus avoiding the problem of the two sides of the housing 20 lifting up when the first suction cup 231 expands the housing 20.

[0064] Optionally, such as Figures 2 to 9 As shown, the electrode group conveying mechanism 500 includes an electrode group gripper assembly 510, an electrode group gripper drive device, and an electrode group conveying mounting plate 530. The electrode group gripper assembly 510 can grip the electrode group 10. The fixed end of the electrode group gripper drive device is fixed to the electrode group conveying mounting plate 530, and the drive end of the electrode group gripper drive device is connected to the electrode group gripper assembly 510 to drive the electrode group gripper assembly 510 to move closer to and away from the electrode group 10. The electrode group conveying mounting plate 530 is movably mounted on the frame to drive the electrode group gripper assembly 510 holding the electrode group 10 to move and send the electrode group 10 into the housing 20 through the second opening 22, so as to realize the assembly of the electrode group 10 and the housing 20. In addition, this structure can also realize the adjustment of the position of the electrode group 10, so that the relative position of the electrode group 10 and the housing 20 is more accurate, further reducing the probability of the electrode group 10 rubbing against the housing 20 when it is installed into the housing 20.

[0065] Preferably, such as Figures 2 to 9 As shown, the pole group gripper drive device includes a first pole group gripper drive device 521 and a second pole group gripper drive device 522. The fixed end of the first pole group gripper drive device 521 is fixed on the pole group conveying mounting plate 530. The drive end of the first pole group gripper drive device 521 is connected to the fixed end of the second pole group gripper drive device 522. The drive end of the second pole group gripper drive device 522 is connected to the pole group gripper assembly 510. By setting two pole group gripper drive devices, the position of the pole group gripper assembly 510 can be controlled in stages to maximize the position of the pole group 10. In the width direction, the coverage size of the Mylar membrane maximizes the area of ​​the Mylar membrane covering the surface of the electrode group 10. In this embodiment, the stroke of the first electrode group gripper drive device 521 is greater than the stroke of the second electrode group gripper drive device 522, forming a configuration where the first electrode group gripper drive device 521 performs coarse adjustment and the second electrode group gripper drive device 522 performs fine adjustment. It is understood that in other embodiments, the stroke of the first electrode group gripper drive device 521 may be less than or equal to the stroke of the second electrode group gripper drive device 522, depending on the actual application requirements. Optionally, the first electrode group gripper drive device 521 and the second electrode group gripper drive device 522 can be reciprocating cylinders or lead screw modules, etc. Optionally, the driving end of the first electrode group gripper drive device 521 and the fixed end of the second electrode group gripper drive device 522 can be connected by hexagonal screws or welding.

[0066] Preferably, such as Figures 2 to 9 As shown, the pole group conveying mounting plate 530 is also provided with a slide rail 540. The first pole group gripper drive device 521 is mounted on the slide rail 540, and the second pole group gripper drive device 522 is provided with a sliding groove. The sliding groove is slidably engaged with the slide rail 540. The slide rail 540 can not only support the first pole group gripper drive device 521 and the second pole group gripper drive device 522, but also guide the movement of the second pole group gripper drive device 522, further improving the accuracy of the pole group gripper drive device in adjusting the position of the pole group gripper assembly 510 and the pole group 10.

[0067] Preferably, such as Figures 2 to 9 As shown, the number of the first pole group gripper drive device 521, the second pole group gripper drive device 522, the pole group gripper assembly 510, and the slide rail 540 are all multiple and arranged in groups. The slide rail 540 in each group is fixed on the pole group conveying mounting plate 530, and the slide rails 540 in the multiple groups are evenly spaced along the length direction of the pole group 10 to improve the clamping force and clamping stability of the pole group conveying mechanism 500 on the pole group 10.

[0068] Preferably, such as Figures 2 to 9As shown, there are two pole group conveying mechanisms 500, which are respectively arranged on opposite sides of the pole group 10 to further improve the clamping force and clamping stability of the pole group 10.

[0069] It should be noted that the specific structures of the above-mentioned film-pulling gripper assembly 431 and electrode group gripper assembly 510 are both relatively mature existing technologies in the field. For example, taking the film-pulling gripper assembly 431 as an example, the film-pulling gripper assembly 431 may include a first gripper, a second gripper and a driving device. The fixed end and the driving end of the driving device are respectively connected to the first gripper and the second gripper. Under the drive of the driving device, the first gripper moves closer to and away from the second gripper to realize the opening and closing of the first gripper and the second gripper.

[0070] The following is a brief description of the operation of the electrode assembly housing device provided in this embodiment. (See attached diagram) Figures 1 to 9 :

[0071] The housing 20 conveying device picks up the housing 20 and conveys the housing 20 between the first positioning block 211 and the third positioning block 221. The two second positioning drive devices 240 drive the first positioning block 211 and the third positioning block 221 respectively to adjust the position of the housing 20. Under the drive of the first positioning drive device, the second positioning block 212 and the fourth positioning block 222 approach the first positioning block 211 and the third positioning block 221 respectively, so that the two sides of the housing 20 are respectively embedded in the first through groove and the second through groove. Pull the spring 233 so that the first suction cup 231 adsorbed on the end face of the housing 20 expands the housing 20.

[0072] The film feeding mechanism 300 clamps a portion of the Mylar film on each of the two Mylar film rolls 100 and pulls the Mylar film toward the first direction D1, so that the Mylar film enters the housing 20 through the first opening 21 and then exits the housing 20 through the second opening 22. At this time, the unwinding machine rotates forward to release the Mylar film.

[0073] The film pulling claw assembly 431 on the film pulling mechanism 400 clamps the Mylar film and pulls the Mylar film to continue moving a certain distance along the first direction D1 before stopping. Under the drive of the film pulling claw drive device 432, the distance between the two film pulling claw assemblies 431 is increased, which increases the distance between the upper and lower Mylar films.

[0074] The electrode assembly conveying mechanism 500 clamps the electrode assembly 10 and moves it between the two Mylar films held by the two film-pulling gripper assemblies 431. The film-pulling gripper drive device 432 drives the film-pulling gripper assemblies 431 again, reducing the distance between the two film-pulling gripper assemblies 431, thus reducing the distance between the upper and lower Mylar films until the two Mylar films cover the upper and lower end faces of the electrode assembly 10 respectively. During the process of the Mylar films covering the end faces of the electrode assembly 10, multiple electrode assembly gripper assemblies, multiple first electrode assembly gripper drive devices 521, and multiple second electrode assembly gripper drive devices 522 cooperate with each other to ensure that the Mylar films can be smoothly... The Mylar membrane is covered on the end face of the electrode group 10. That is, when the Mylar membrane is about to cover a certain area of ​​the electrode group 10, the corresponding electrode group gripper assembly releases the electrode group 10, and the first electrode group gripper drive device 521 and the second electrode group gripper drive device 522 cooperate to move the electrode group gripper assembly away from the electrode group 10, thereby avoiding the Mylar membrane. After the Mylar membrane covers the area of ​​the electrode group 10, the corresponding first electrode group gripper drive device 521 and the second electrode group gripper drive device 522 cooperate to move the electrode group gripper assembly closer to the electrode group 10 and clamp the electrode group 10. During this process, the other electrode group gripper assemblies are always in the state of clamping the electrode group 10.

[0075] Driven by the hot melt drive device 412, the hot melt metal part 411 moves toward the Mylar film and heat melts part of the Mylar film covering the end face of the electrode group 10 onto the end face of the electrode group 10.

[0076] The electrode assembly conveying mechanism 500 conveys the electrode assembly 10 to move in the second direction D2 and allows the electrode assembly 10 to enter the housing 20 through the second opening 22 until the electrode assembly 10 is completely fed into the housing 20. During the process of the electrode assembly 10 entering the housing 20, multiple electrode assembly gripper assemblies arranged along the first direction D1 sequentially release the electrode assembly 10 to allow the housing 20 to be positioned. During this process, the film feeding mechanism 300 moves synchronously along the second direction D2 until it completely exits through the first opening 21. During this process, the Mylar film located between the electrode assembly 10 and the Mylar film roll 100 is retracted onto the Mylar film roll 100 under the action of the reversing action of the unwinding machine. It should be noted that when the film feeding mechanism 300 moves synchronously along the second direction D2, the film feeding mechanism 300 can either always hold the Mylar film or release the Mylar film.

[0077] Driven by the film cutting drive device 620, the metal wire 642 approaches the Mylar film and melts the Mylar film, thereby completing the process of covering the end face of the electrode assembly 10 with the Mylar film and the process of installing the electrode assembly 10 into the housing 20.

[0078] Driven by the first positioning drive device, the second positioning block 212 and the fourth positioning block 222 move away from the first positioning block 211 and the third positioning block 221 respectively. The housing conveying mechanism 700 carries the assembly of the electrode group 10 and the housing 20 to the designated position, completing the unloading process of the assembly of the electrode group 10 and the housing 20.

[0079] The electrode assembly housing device provided in this embodiment, by setting a film feeding mechanism 300 and a film pulling mechanism 400, covers the end face of the electrode assembly 10 with Mylar film. When the electrode assembly 10 is installed into the housing 20, the Mylar film effectively separates the electrode assembly 10 and the housing 20, avoiding the problem of scratching between the electrode assembly 10 and the housing 20, thus protecting the electrode assembly 10 and improving the battery product qualification rate and battery product safety. Secondly, the hot-melt assembly and the film cutting mechanism 600 are set to achieve the effect of covering the end face of the electrode assembly 10 with Mylar film. Furthermore, the housing positioning mechanism 200 is equipped with a first suction cup 231, which is adsorbed onto the end face of the housing 20 and expands the housing 20, making it easier for the electrode assembly 10 to be smoothly installed into the housing 20. This design reduces the likelihood of the electrode assembly 10 rubbing against the housing 20 when it is installed. Simultaneously, a first positioning part 210 and a second positioning part 220 are provided. A first through groove of equal length to the housing 20 is provided on the first positioning part 210, and a second through groove of equal length to the housing 20 is provided on the second positioning part 220. The portion of the housing 20 closest to the first positioning part 210 is embedded in the first through groove, and the portion of the housing 20 closest to the second positioning part 220 is embedded in the second through groove. The first and second through grooves limit the movement of the two sides of the housing 20, preventing warping when the housing 20 is expanded, reducing the likelihood of deformation, and resulting in better overall structural consistency of the housing 20, thereby improving the yield rate.

[0080] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
