[0031] Currently, market developments indicate that battery devices are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric vehicles, as well as in energy storage devices such as energy storage containers and energy storage cabinets, and in a variety of fields, including aerospace.

[0032] The battery device referred to in the embodiments of this application refers to a single physical module that includes one or more battery cells to provide higher voltage and capacity. In the embodiments of this application, the battery cells may be secondary batteries, which are battery cells that can be recharged to activate the active materials after discharge and continue to be used.

[0034] A battery cell typically includes an electrode assembly. This assembly includes a positive electrode, a negative electrode, and a separator. During the charge and discharge process, active ions (such as lithium ions) are intercalated and released between the positive and negative electrodes. A separator, positioned between the positive and negative electrodes, prevents short circuits while allowing the active ions to pass through. For example, the electrode assembly includes a stacked positive electrode sheet, a negative electrode sheet, and a separator.

[0035] In some embodiments, the electrode assembly may be a wound structure.

[0036] Currently, continuous winding is commonly used for wound electrode assemblies. This involves applying tape to the leading and trailing ends of the electrode sheets to connect adjacent electrode sheets for continuous winding. In some cases, when applying the tape to the electrode sheets, defects such as wrinkling of the tape and the formation of air bubbles between the tape and the electrode sheet can occur. This not only reduces the quality of the tape application but also increases the risk of wrinkling the electrode sheets, posing a threat to the reliability of the battery device.

[0037] In order to reduce the risk of wrinkling of the electrode sheet and improve the reliability of the battery device, some embodiments of the present application provide a electrode sheet gluing device, which includes a clamping assembly and a gluing assembly, the clamping assembly includes two first clamping mechanisms arranged opposite to each other along the second direction and two second clamping mechanisms arranged opposite to each other along the second direction, the two first clamping mechanisms can clamp the first electrode sheet from both sides of the second direction, and the two second clamping mechanisms can clamp the second electrode sheet from both sides of the second direction; the gluing assembly includes an adsorption plate, a driver and a scraping structure, the scraping structure is movably connected to the adsorption plate along a third direction, the scraping structure is transmission-connected to the driver, the adsorption plate is used to adsorb the tape and attach the tape to the first electrode sheet and the second electrode sheet, and the tape covers the gap between the first electrode sheet and the second electrode sheet; driven by the driver, the scraping structure can move along the third direction and scrape the tape from the side of the tape close to the adsorption plate, and the first direction, the second direction and the third direction are perpendicular to each other.

[0038] In the above structure, since the adsorption plate used for adsorbing the tape is movably connected to a scraping structure along the third direction, after the adsorption plate attaches the tape to the first electrode and the second electrode, the scraping structure can move along the third direction and scrape the tape from the side of the tape close to the adsorption plate, so that the scraping structure can scrape the two ends of the tape in sequence along the third direction, which not only can flatten the tape, but also can squeeze out the bubbles between the tape and the first electrode or the second electrode, reducing the risk of wrinkling the tape attached to the first electrode or the second electrode, thereby reducing the risk of wrinkling the electrode, which is beneficial to improving the reliability of the battery device.

[0039] The electrode gluing device provided in the embodiment of the present application can be applied to the winding and forming of electrode assemblies. The manufactured electrode assemblies can be used to produce battery devices. The manufactured battery devices can be vehicles, mobile phones, portable devices, laptop computers, ships, spacecraft, electric toys, electric tools, etc. Vehicles can be fuel vehicles, gas vehicles, or new energy vehicles. New energy vehicles can be pure electric vehicles, hybrid vehicles, or extended-range vehicles. Spacecraft include airplanes, rockets, space shuttles, and spacecraft. Electric toys include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys.

[0040] The pole piece gluing device provided in an embodiment of the present application can also be used to attach tape to two sheets to connect the two sheets. The pole piece gluing device can improve the quality of attaching tape to the sheets.

[0041] The electrode gluing device and method thereof, and the battery device production system provided by the present application are further described below with reference to the accompanying drawings and through specific implementation methods.

[0042] Some embodiments of the present application provide a pole piece gluing device, referring to Figure 1 The electrode gluing device includes a clamping component 1 and a gluing component 2. The clamping component 1 includes two first clamping mechanisms 11 relatively arranged along the second direction Y and two second clamping mechanisms 12 relatively arranged along the second direction Y. The two first clamping mechanisms 11 can clamp the first electrode 10 from both sides of the second direction Y, and the two second clamping mechanisms 12 can clamp the second electrode 20 from both sides of the second direction Y; the gluing component 2 includes an adsorption plate 21, a driver and a scraping structure 23. The scraping structure 23 is movably connected to the adsorption plate 21 along the third direction Z. The scraping structure 23 is transmission-connected to the driver. The adsorption plate 21 is used to adsorb the tape and attach the tape to the first electrode 10 and the second electrode 20. The tape covers the gap 30 between the first electrode 10 and the second electrode 20. Driven by the driver, the scraping structure 23 can move along the third direction Z and scrape the tape from the side of the tape close to the adsorption plate 21. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0043] The pole piece gluing device is used to apply tape to the first pole piece 10 and the second pole piece 20 spaced apart along the first direction X to connect the first pole piece 10 and the second pole piece 20. The tape is bonded to the first pole piece 10 and the second pole piece 20 and covers the gap 30 between the first pole piece 10 and the second pole piece 20.

[0044] The clamping assembly 1 can be a plurality of components for clamping the first pole piece 10 and the second pole piece 20. It fixes the first pole piece 10 and the second pole piece 20 by clamping the first pole piece 10 and the second pole piece 20 so that tape can be attached to the first pole piece 10 and the second pole piece 20 later.

[0045] The first clamping mechanism 11 may be a mechanism for clamping the first pole piece 10, and fixes the first pole piece 10 by clamping the first pole piece 10. The second clamping mechanism 12 may be a mechanism for clamping the second pole piece 20, and fixes the second pole piece 20 by clamping the second pole piece 20.

[0046] By arranging the two first clamping mechanisms 11 relatively spaced apart along the second direction Y, the two first clamping mechanisms 11 can clamp the first pole piece 10 from both sides in the second direction Y by approaching each other. By arranging the two second clamping mechanisms 12 relatively spaced apart along the second direction Y, the two second clamping mechanisms 12 can clamp the second pole piece 20 from both sides in the second direction Y by approaching each other.

[0047] Exemplarily, the first clamping mechanism 11 and the second clamping mechanism 12 are arranged relatively spaced apart in the first direction X, and the gap 30 between the first pole piece 10 and the second pole piece 20 is located between the first clamping mechanism 11 and the second clamping mechanism 12 .

[0048] The first clamping mechanism 11 clamps the first pole piece 10, and it can be that when the two first clamping mechanisms 11 clamp the first pole piece 10 from both sides of the second direction Y, part of the first pole piece 10 can extend from between the two first clamping mechanisms 11, and the tape can be attached to the part of the first pole piece 10 extending from between the two first clamping mechanisms 11; the second clamping mechanism 12 clamps the second pole piece 20, and it can be that when the two second clamping mechanisms 12 clamp the second pole piece 20 from both sides of the second direction Y, part of the second pole piece 20 can extend from between the two second clamping mechanisms 12, and the tape can be attached to the part of the second pole piece 20 extending from between the two second clamping mechanisms 12, and the part of the first pole piece 10 extending from between the two first clamping mechanisms 11 and the part of the second pole piece 20 extending from between the two second clamping mechanisms 12 are spaced apart in the first direction X to form a gap 30.

[0049] The adhesive component 2 may be a component for attaching adhesive tape to the first pole piece 10 and the second pole piece 20 . The attached adhesive tape can connect the first pole piece 10 and the second pole piece 20 and cover the gap 30 between the first pole piece 10 and the second pole piece 20 .

[0050] The adsorption plate 21 can be used to carry and transport the tape in the adhesive component 2 to attach the tape to the surface of the first electrode 10 and the surface of the second electrode 20, and cover the gap 30 between the first electrode 10 and the second electrode 20, so that the tape can connect the first electrode 10 and the second electrode 20.

[0051] Exemplarily, the adsorption plate 21 can be a plate-shaped device with electrostatic adsorption capability, which can stably adsorb the tape on the surface facing the pole piece; the adsorption plate 21 can also be provided with adsorption holes 212, and the adsorption plate 21 can stably adsorb the tape on the surface facing the pole piece through the adsorption holes 212 for suction.

[0052] The scraping structure 23 can be a structure in the glue assembly 2 for scraping the tape attached to the electrode, which can improve the adhesion effect of the tape on the electrode. The scraping structure 23 is movably connected to the adsorption plate 21 along the third direction Z, which can mean that the scraping structure 23 is connected to the adsorption plate 21, and the scraping structure 23 can be moved along the third direction Z so as to scrape the tape by moving. Exemplarily, the scraping structure 23 can be configured as a scraper structure or a roller structure. Those skilled in the art can select the structural style of the scraping structure 23 according to actual conditions, as long as the scraping structure 23 can scrape the tape attached to the electrode.

[0053] The driver can be a device for driving the scraping structure 23 to move along the third direction Z, providing power for the movement of the scraping structure 23. By connecting the scraping structure 23 to the driver through a transmission connection, the scraping structure 23 can be driven by the driver to move along the third direction Z. For example, the driver can be a linear motor or a hydraulic cylinder, so that the driver can drive the scraping structure 23 to move along the third direction Z.

[0054] After the adsorption plate 21 attaches the tape to the first electrode 10 and the second electrode 20, the driver is activated, and the scraping structure 23 moves along the third direction Z driven by the driver, and scrapes from the side of the tape close to the adsorption plate 21, so that the scraping structure 23 can scrape the two ends of the tape in sequence along the third direction Z, which not only makes the tape flat, but also squeezes out the bubbles between the tape and the first electrode 10 or the second electrode 20.

[0055] By making the first direction X, the second direction Y and the third direction Z perpendicular to each other, the two first clamping mechanisms 11 can clamp the first pole piece 10 from a direction perpendicular to the setting direction of the first pole piece 10 and the second pole piece 20, and the two second clamping mechanisms 12 can clamp the second pole piece 20 from a direction perpendicular to the setting direction of the first pole piece 10 and the second pole piece 20, so that the scraping structure 23 can scrape the tape along a direction perpendicular to the setting direction of the first pole piece 10 and the second pole piece 20 and the clamping direction of the pole pieces by the clamping assembly 1.

[0056] In the above structure, since the adsorption plate 21 for adsorbing the tape is movably connected to the scraping structure 23 along the third direction Z, after the adsorption plate 21 attaches the tape to the first electrode 10 and the second electrode 20, the scraping structure 23 can move along the third direction Z and scrape the tape from the side of the tape close to the adsorption plate 21, so that the scraping structure 23 can scrape the two ends of the tape in turn along the third direction Z, which not only can make the tape flat, but also can squeeze out the bubbles between the tape and the first electrode 10 or the second electrode 20, thereby reducing the risk of wrinkling the tape attached to the first electrode 10 or the second electrode 20, thereby reducing the risk of wrinkling the electrode, which is beneficial to improving the reliability of the battery device.

[0057] In some embodiments, two scraping structures 23 are provided on the adsorption plate 21 and are arranged opposite to each other along the first direction X. One of the two scraping structures 23 is used to scrape the portion of the tape attached to the first electrode 10, and the other is used to scrape the portion of the tape attached to the second electrode 20.

[0058] The adsorption plate 21 is provided with two scraping structures 23 that are oppositely arranged along the first direction X. This may mean that the adsorption plate 21 is provided with two scraping structures 23 , and the two scraping structures 23 are oppositely arranged along the first direction X at intervals.

[0059] One of the two scraping structures 23 can be driven by the driver to move along the third direction Z to scrape the part of the tape attached to the first pole piece 10 so that the tape can be evenly attached to the first pole piece 10; the other can be driven by the driver to move along the third direction Z to scrape the part of the tape attached to the second pole piece 20 so that the tape can be evenly attached to the second pole piece 20.

[0060] Exemplarily, the two leveling structures 23 provided on the adsorption plate 21 are arranged at relative intervals along the first direction X, one leveling structure 23 is arranged opposite to the portion of the tape attached to the first pole piece 10 along the second direction Y, and the other leveling structure 23 is arranged opposite to the portion of the tape attached to the second pole piece 20 along the second direction Y, and the gap between the two leveling structures 23 is opposite to the gap 30 between the first pole piece 10 and the second pole piece 20 along the second direction Y.

[0061] In some embodiments, reference Figure 2 The surface of the adsorption tape on the adsorption plate 21 is recessed with a groove 211 , which extends along the third direction Z. At least a portion of the leveling structure 23 is disposed in the groove 211 .

[0062] The groove 211 may be a structure provided on the suction plate 21 for accommodating the leveling structure 23. At least a portion of the leveling structure 23 is provided in the groove 211. Alternatively, a portion of the leveling structure 23 may be provided in the groove 211, while another portion of the leveling structure 23 extends outside the groove 211. Alternatively, the entire leveling structure 23 may be provided in the groove 211. By providing at least a portion of the leveling structure 23 in the groove 211, the protrusion of the leveling structure 23 from the suction plate 21 can be reduced, thereby facilitating the flattening of the adhesive tape on the suction plate 21 and improving the quality of the adhesive tape adhered to the first and second pole pieces 10 and 20.

[0063] By extending the groove 211 along the third direction Z, the scraping structure 23 at least partially disposed in the groove 211 can move along the third direction Z in the groove 211 .

[0064] For example, machining such as milling may be used to remove material from the surface of the adsorption tape of the adsorption plate 21 , so that the surface of the adsorption tape of the adsorption plate 21 is recessed inward to form a groove 211 .

[0065] In some embodiments, the scraping structure 23 is accommodated in the groove 211 , and the end of the scraping structure 23 close to the tape is flush with the surface of the tape adsorbed by the adsorption plate 21 ; or, the end of the scraping structure 23 close to the tape protrudes outside the groove 211 .

[0066] The scraping structure 23 is accommodated in the groove 211, which may mean that the entire scraping structure 23 is completely accommodated in the groove 211. The end of the scraping structure 23 close to the tape is flush with the surface of the tape adsorbed by the adsorption plate 21, which may mean that when the entire scraping structure 23 is completely accommodated in the groove 211, the end of the scraping structure 23 close to the tape is located in the plane where the surface of the tape adsorbed by the adsorption plate 21 is located. This not only allows the end of the scraping structure 23 close to the tape to push the tape to be attached to the pole piece together with the surface of the tape adsorbed by the adsorption plate 21 when the adsorption plate 21 adsorbs the tape and attaches the tape to the pole piece, but also allows the scraping structure 23 to maintain contact with the tape when it moves along the third direction Z, and can scrape the surface of the tape close to the adsorption plate 21, so as to flatten the tape and squeeze out the bubbles between the tape and the pole piece.

[0067] The end of the scraping structure 23 close to the tape protrudes out of the groove 211. Alternatively, the end of the scraping structure 23 close to the tape protrudes outward from the opening of the groove 211, and the rest of the scraping structure 23 is located in the groove 211. By making the end of the scraping structure 23 close to the tape protrude out of the groove 211, not only can the end of the scraping structure 23 close to the tape work together with the surface of the adsorption plate 21 adsorbing the tape to push the tape to the electrode when the adsorption plate 21 adsorbs the tape and attaches the tape to the electrode, but also when the scraping structure 23 moves along the third direction Z, the scraping structure 23 can effectively maintain contact with the tape, thereby flattening the tape and squeezing out bubbles between the tape and the electrode.

[0068] In some embodiments, reference Figure 3 The scraping structure 23 includes a connecting portion 231 and a scraping portion 232 that are connected to each other. The connecting portion 231 is located in the groove 211 and is slidably connected to the inner wall of the groove 211. The end of the scraping portion 232 close to the tape protrudes out of the groove 211. The scraping portion 232 is configured as an elastic member and is used to scrape the tape.

[0069] The connecting portion 231 and the scraping portion 232 are two interconnected parts of the scraping structure 23. Among them, the connecting portion 231 is the part of the scraping structure 23 used to connect with the adsorption plate 21, and the scraping portion 232 is the part of the scraping structure 23 that contacts the tape to scrape the tape.

[0070] The connecting portion 231 is located in the groove 211 and is slidably connected to the inner wall of the groove 211. The connecting portion 231 can be accommodated in the groove 211, and a sliding groove is provided on the inner wall of the groove 211. The connecting portion 231 is slidably connected to the sliding groove, so that the scraping structure 23 can be slidably connected to the groove 211.

[0071] The end of the scraping portion 232 close to the tape protrudes outside the groove 211. It can be that the scraping portion 232 connected to the connecting portion 231 extends from the opening of the groove 211, and the end of the scraping portion 232 close to the tape protrudes outside the groove 211, so that the end of the scraping portion 232 protruding outside the groove 211 can apply a greater resistance force to the tape attached to the electrode, so that the tape can be better scraped flat.

[0072] The flattening portion 232 is configured as an elastic member, which may mean that the flattening portion 232 is elastically deformable. For example, the flattening portion 232 may be made of elastic rubber. By configuring the flattening portion 232 as an elastic member, the flattening portion 232 is elastically deformable when contacting the tape attached to the electrode. This not only enables the flattening portion 232 to provide a stable holding force to the tape, but also reduces the possibility of hard contact between the flattening portion 232 and the tape, thereby reducing the possibility of damage to the tape.

[0073] In some embodiments, the scraping portion 232 is configured as a roller, and the central axis of the roller is arranged along the first direction X.

[0074] By configuring the scraping portion 232 as a roller and setting the central axis of the roller along the first direction X, when the roller is driven by the driver to move along the third direction Z, the contact between the roller and the tape is rolling contact, which reduces the friction between the roller and the tape and helps to reduce the possibility of damage to the tape.

[0075] In some embodiments, the adsorption plate 21 is provided with adsorption holes 212 , and the openings of the adsorption holes 212 are provided on the surface of the adsorption tape of the adsorption plate 21 ; the adhesive component 2 also includes a negative pressure air source, which is connected to the adsorption holes 212 .

[0076] The adsorption hole 212 may be an air hole provided on the adsorption plate 21 for absorbing air. The opening of the adsorption hole 212 is provided on the surface of the adsorption tape of the adsorption plate 21, which may mean that the adsorption hole 212 is connected to the surface of the adsorption tape of the adsorption plate 21. By providing the opening of the adsorption hole 212 on the surface of the adsorption tape of the adsorption plate 21, the adsorption hole 212 can absorb air from the surface of the adsorption tape of the adsorption plate 21, which not only enables the tape to be adsorbed on the surface of the adsorption plate 21, thereby achieving stable bearing of the tape by the adsorption plate 21, but also can absorb dust from the bonding site, which is beneficial to improving the bonding quality of the tape on the electrode, and is more conducive to the discharge of bubbles between the tape and the electrode.

[0077] The negative pressure air source can be an air source capable of providing a stable negative pressure. By being in communication with the adsorption holes 212, the negative pressure air source enables the adsorption holes 212 to maintain stable air suction, thereby enabling the adsorption plate 21 to stably support the tape. For example, the negative pressure air source can be provided by a Roots vacuum pump, enabling the negative pressure air source to maintain stable air suction in the adsorption holes 212.

[0078] In some embodiments, the electrode laminating device further includes an image acquisition unit (not shown in the figure) and a control unit (not shown in the figure). The image acquisition unit is used to acquire an image at the gap 30. The control unit is communicatively connected with the image acquisition unit, the first clamping mechanism 11 and the second clamping mechanism 12. The control unit can control the first clamping mechanism 11 and the second clamping mechanism 12 to adjust the relative positions of the first electrode 10 and the second electrode 20 according to the image.

[0079] The image acquisition unit may be a device for acquiring an image at the gap 30 between the first pole piece 10 and the second pole piece 20. For example, the image acquisition unit may be spaced apart from the gap 30 between the first pole piece 10 and the second pole piece 20 in the second direction Y, and may be capable of acquiring an image at the gap 30 between the first pole piece 10 and the second pole piece 20.

[0080] Exemplarily, the image acquisition unit may include a charge coupled device (CCD) image acquisition unit. The CCD image acquisition unit has the advantages of high sensitivity, resistance to strong light, and small distortion, which is beneficial to improving the quality of the image obtained at the gap 30 between the first pole piece 10 and the second pole piece 20, and is beneficial to improving the accuracy of the position adjustment of the first pole piece 10 and the second pole piece 20.

[0081] The pixel value range of the image acquisition unit can be set to 30 million to 60 million, so that the image acquired by the image acquisition unit has a higher definition. Exemplarily, the pixel value of the image acquisition unit can be set to 40 million, 50 million, or 60 million. Those skilled in the art can set the pixel value of the image acquisition unit according to actual conditions. Exemplarily, the pixel value range of the image acquisition unit can be set to 40 million to 50 million, which not only makes the image acquired by the image acquisition unit have a higher definition, but also reduces the cost increase caused by using an image acquisition unit with an excessively high pixel value.

[0082] The control unit may be an industrial control computer that can perform numerical and logical calculations and has a storage and memory function. The control unit may store and execute a program for determining whether the first pole piece 10 and the second pole piece 20 are aligned, and a program for controlling the first clamping mechanism 11 and the second clamping mechanism 12 to adjust the relative positions of the first pole piece 10 and the second pole piece 20.

[0083] By communicating with the control unit, the image acquisition unit, the first clamping mechanism 11 and the second clamping mechanism 12, the control unit can control the first clamping mechanism 11 and the second clamping mechanism 12 to adjust the relative positions of the first electrode 10 and the second electrode 20 according to the image, which not only can adjust the first electrode 10 and the second electrode 20 to be relatively spaced along the first direction X and not easily misplaced; it can also adjust the size of the gap 30 between the first electrode 10 and the second electrode 20 in the first direction X to be within a preset range, which is beneficial to improving the quality of the connection between the tape and the first electrode 10 and the second electrode 20.

[0084] In some embodiments, the electrode laminating device also includes a support assembly 5, which includes two third clamping mechanisms 51 arranged relatively to each other along the second direction Y and two fourth clamping mechanisms 52 arranged relatively to each other along the second direction Y. The third clamping mechanism 51 is spaced apart from the first clamping mechanism 11, and the two third clamping mechanisms 51 can clamp the first electrode 10 from both sides of the second direction Y; the fourth clamping mechanism 52 is spaced apart from the second clamping mechanism 12, and the two fourth clamping mechanisms 52 can clamp the second electrode 20 from both sides of the second direction Y.

[0085] The support assembly 5 can be a plurality of components for supporting the first pole piece 10 and the second pole piece 20. It clamps the first pole piece 10 and the second pole piece 20 to fix the positions of the first pole piece 10 and the second pole piece 20, thereby reducing the possibility of movement of the first pole piece 10 and the second pole piece 20 when attaching the tape.

[0086] The third clamping mechanism 51 may be a mechanism for clamping the first pole piece 10, and fixes the first pole piece 10 by clamping the first pole piece 10. The fourth clamping mechanism 52 may be a mechanism for clamping the second pole piece 20, and fixes the second pole piece 20 by clamping the second pole piece 20.

[0087] By arranging the two third clamping mechanisms 51 relatively spaced apart along the second direction Y, the two third clamping mechanisms 51 can clamp the first pole piece 10 from both sides in the second direction Y by approaching each other. By arranging the two second clamping mechanisms 12 relatively spaced apart along the second direction Y, the two second clamping mechanisms 12 can clamp the first pole piece 10 from both sides in the second direction Y by approaching each other.

[0088] The third clamping mechanism 51 is spaced apart from the first clamping mechanism 11. It can be that the third clamping mechanism 51 and the first clamping mechanism 11 are spaced apart along the first direction X. The third clamping mechanism 51 can clamp the part of the first pole piece 10 away from the first clamping mechanism 11, so that the first pole piece 10 can be clamped from both ends by the first clamping mechanism 11 and the third clamping mechanism 51, so that the position of the first pole piece 10 is stable.

[0089] The two third clamping mechanisms 51 clamp the first pole piece 10 from both sides in the second direction Y, and can firmly fix the first pole piece 10 to reduce the possibility of its position shifting.

[0090] By arranging the two fourth clamping mechanisms 52 relatively spaced apart along the second direction Y, the two fourth clamping mechanisms 52 can clamp the second pole piece 20 from both sides in the second direction Y by approaching each other. By arranging the two fourth clamping mechanisms 52 relatively spaced apart along the second direction Y, the two fourth clamping mechanisms 52 can clamp the second pole piece 20 from both sides in the second direction Y by approaching each other.

[0091] The fourth clamping mechanism 52 is spaced apart from the second clamping mechanism 12. The fourth clamping mechanism 52 and the second clamping mechanism 12 are spaced apart along the first direction X. The fourth clamping mechanism 52 can clamp the part of the second pole piece 20 away from the second clamping mechanism 12, so that the second pole piece 20 can be clamped from both ends by the second clamping mechanism 12 and the fourth clamping mechanism 52, so that the position of the second pole piece 20 is stable.

[0092] The two fourth clamping mechanisms 52 clamp the second pole piece 20 from both sides in the second direction Y, and can firmly fix the second pole piece 20 to reduce the possibility of positional displacement.

[0093] The present application also provides a battery device production system, which includes the electrode gluing device provided by the above technical solution.

[0094] The present application also provides a pole piece gluing method, which is used to connect the first pole piece 10 and the second pole piece 20 spaced apart along the first direction X. Figure 4 , the pole piece gluing method includes: S1. Provide a clamping assembly 1, which includes two first clamping mechanisms 11 arranged opposite to each other along the second direction Y and two second clamping mechanisms 12 arranged opposite to each other along the second direction Y; the two first clamping mechanisms 11 clamp the first pole piece 10 from both sides of the second direction Y, and the two second clamping mechanisms 12 clamp the second pole piece 20 from both sides of the second direction Y.

[0095] In the above step S1, when the two first clamping mechanisms 11 clamp the first pole piece 10 from both sides of the second direction Y, part of the first pole piece 10 can extend from between the two first clamping mechanisms 11; when the two second clamping mechanisms 12 clamp the second pole piece 20 from both sides of the second direction Y, part of the second pole piece 20 can extend from between the two second clamping mechanisms 12; the part of the first pole piece 10 extending from between the two first clamping mechanisms 11 and the part of the second pole piece 20 extending from between the two second clamping mechanisms 12 are spaced apart in the first direction X to form a gap 30.

[0096] S2. Provide a glue-applying assembly 2, which includes an adsorption plate 21, a driver and a scraping structure 23. The scraping structure 23 is movably connected to the adsorption plate 21 along the third direction Z, and the scraping structure 23 is connected to the driver for transmission; the adsorption plate 21 adsorbs the tape and attaches the tape to the first pole piece 10 and the second pole piece 20, and the tape covers the gap 30 between the first pole piece 10 and the second pole piece 20.

[0097] In the above step S2, the adsorption plate 21 adsorbs the tape and attaches the tape to the first electrode 10 and the second electrode 20, wherein the tape covers the gap 30 between the first electrode 10 and the second electrode 20, and the tape realizes the connection between the first electrode 10 and the second electrode 20.

[0098] S3. The driver drives the scraping structure 23 to move along the third direction Z, so that the scraping structure 23 scrapes the tape from the side of the tape close to the adsorption plate 21 along the third direction Z. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0099] In the above step S3, the driver drives the scraping structure 23 to move along the third direction Z, so that the scraping structure 23 can move along the third direction Z and scrape the tape from the side of the tape close to the adsorption plate 21, so that the scraping structure 23 can scrape the two ends of the tape in sequence along the third direction Z, which not only can make the tape flat, but also can squeeze out the bubbles between the tape and the first pole piece 10 or the second pole piece 20, thereby reducing the risk of wrinkling the tape attached to the first pole piece 10 or the second pole piece 20, thereby reducing the risk of wrinkling the pole piece, which is beneficial to improving the reliability of the battery device.

[0100] In some embodiments, in step S2, a glue-applying assembly 2 is provided, the glue-applying assembly 2 including an adsorption plate 21, a driver, and a scraping structure 23. The scraping structure 23 is movably connected to the adsorption plate 21 along the third direction Z, and the scraping structure 23 is in transmission connection with the driver. The adsorption plate 21 adsorbs the adhesive tape and attaches the adhesive tape to the first electrode 10 and the second electrode 20. Before the adhesive tape covers the gap 30 between the first electrode 10 and the second electrode 20, the electrode gluing method further includes: S20. Provide an image acquisition unit and a control unit, the control unit is in communication with the image acquisition unit, the first clamping mechanism 11 and the second clamping mechanism 12; the image acquisition unit acquires an image at the gap 30, and the control unit controls the first clamping mechanism 11 and the second clamping mechanism 12 to adjust the relative positions of the first pole piece 10 and the second pole piece 20 according to the image, so that the first pole piece 10 and the second pole piece 20 are aligned.

[0101] In the above step S20, the control unit controls the first clamping mechanism 11 and the second clamping mechanism 12 to adjust the relative positions of the first electrode 10 and the second electrode 20 according to the image captured by the image acquisition unit. This not only allows the first electrode 10 and the second electrode 20 to be adjusted to be relatively spaced apart along the first direction X so that the first electrode 10 and the second electrode 20 are aligned and not easily misplaced; it also allows the size of the gap 30 between the first electrode 10 and the second electrode 20 in the first direction X to be within a preset range, which is beneficial to improving the quality of the connection between the tape and the first electrode 10 and the second electrode 20.

[0102] In some embodiments, the adsorption plate 21 is provided with adsorption holes 212, and the openings of the adsorption holes 212 are provided on the surface of the adsorption tape of the adsorption plate 21; the gluing assembly 2 further includes a negative pressure air source, which is connected to the adsorption holes 212; while the driver drives the scraping structure 23 to move along the third direction Z so that the scraping structure 23 scrapes the tape from the side of the tape close to the adsorption plate 21 along the third direction Z, the electrode gluing method further includes: The negative pressure air source keeps sucking air to the position where the tape is attached through the adsorption holes 212 .

[0103] While the scraping structure 23 is scraping the tape, the negative pressure air source keeps sucking air to the position where the tape is attached through the adsorption hole 212, which can form a negative pressure environment on the outside of the tape, which is conducive to squeezing out the bubbles between the tape and the electrode, and is conducive to improving the bonding quality between the tape and the electrode.

[0104] Some embodiments of the present application provide a pole piece gluing device for connecting a first pole piece 10 and a second pole piece 20 spaced apart along a first direction X. The pole piece gluing device includes a clamping assembly 1 and a gluing assembly 2. The clamping assembly 1 includes two first clamping mechanisms 11 disposed oppositely along a second direction Y and two second clamping mechanisms 12 disposed oppositely along the second direction Y. The two first clamping mechanisms 11 are capable of clamping the first pole piece 10 from both sides in the second direction Y, and the two second clamping mechanisms 12 are capable of clamping the second pole piece 20 from both sides in the second direction Y. Two leveling structures 23 of the gluing assembly 2 are disposed oppositely along the first direction X and are at least partially located in a groove 211. The leveling structures 23 are slidably connected to the groove 211 along a third direction Z. Driven by a driver, the leveling structures 23 are capable of moving along the third direction Z and scraping the tape from the side of the tape close to the adsorption plate 21.

[0105] In the above structure, since the adsorption plate 21 for adsorbing the tape is movably connected to the scraping structure 23 along the third direction Z, after the adsorption plate 21 attaches the tape to the first electrode 10 and the second electrode 20, the scraping structure 23 can move along the third direction Z and scrape the tape from the side of the tape close to the adsorption plate 21, so that the scraping structure 23 can scrape the two ends of the tape in turn along the third direction Z, which not only can make the tape flat, but also can squeeze out the bubbles between the tape and the first electrode 10 or the second electrode 20, thereby reducing the risk of wrinkling the tape attached to the first electrode 10 or the second electrode 20, thereby reducing the risk of wrinkling the electrode, which is beneficial to improving the reliability of the battery device.
