[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority based on Chinese patent application 2023116415278 filed on November 30, 2023, and all of its contents are incorporated herein by reference. Technical Field

[0003] The present application relates to the field of battery processing technology, and in particular to a hot pressing roller mechanism, a pressing roller mechanism, a gluing device and a battery production system. Background Art

[0004] The manufacturing process of battery pole pieces may require the pole pieces to be glued. Among them, the adhesive tape attached to the battery cell includes a substrate film, an adhesive film and a release film stacked in sequence.

[0005] With the development of technology, the requirements for the yield of glue lamination are getting higher and higher.

[0006] Summary of the Invention

[0007] The present application provides a hot pressing roller mechanism, a pressing roller mechanism, a gluing device and a battery production system to improve the gluing yield.

[0008] In order to solve the above-mentioned technical problems, the first aspect of the present application provides a hot pressing roller mechanism, comprising: a hot pressing roller and a heating component, wherein the heating component is spaced apart from the hot pressing roller; the heating component is configured to perform non-contact heating on the hot pressing roller. By adopting non-contact heating, no structural parts are introduced on the surface of the hot pressing roller, which can improve the phenomenon of foreign matter being introduced on the surface of the electrode during the hot pressing of the electrode by the hot pressing roller, thereby improving the yield rate of glue lamination. The hot pressing roller mechanism is used to hot press the electrode after glue lamination, and the tape on the surface of the electrode is smoothed and compacted, thereby strengthening the tightness of the fit between the tape and the electrode, thereby improving the yield rate of glue lamination.

[0009] In one embodiment, the device further includes a heat press base, the heat press roller and the heating assembly are respectively connected to the heat press base, the heat press base has a through hole corresponding to the heat press roller, and the heat press roller and the heating assembly are respectively disposed at two opposite ends of the through hole; the heating assembly is a heat radiation assembly or a hot air blowing assembly. Heat from the heating assembly is transferred to the heat press roller through the through hole, achieving non-contact heating.

[0010] In one embodiment, the device further includes a hot pressing base, wherein the hot pressing roller and the heating assembly are respectively connected to the hot pressing base, and the orthographic projection of the hot pressing roller on the hot pressing base at least partially overlaps with the orthographic projection of the heating assembly on the hot pressing base. The hot pressing base is made of a transparent material, and the heating assembly is a heat radiating assembly. Heat from the heating assembly is transferred to the hot pressing roller through the transparent hot pressing base, achieving non-contact heating. By ensuring that the orthographic projections of the hot pressing roller and the heating assembly on the hot pressing base at least partially overlap, the heat conduction path is shortened, thereby improving heat utilization.

[0011] In one embodiment, the heating assembly is a hot air blower assembly, the air outlet direction of the hot air blower assembly is perpendicular to the axial direction of the hot pressing roller, and the angle between the air outlet direction of the hot air blower assembly and the electrode sheet transport direction is 30-60 degrees. The angle between the air outlet direction of the heating assembly and the electrode sheet transport direction is 30-60 degrees, which reduces interference with the hot pressing roller's squeezing of the electrode sheet, while achieving efficient heating of the hot pressing roller and achieving a better hot pressing effect.

[0012] In one embodiment, along the axial direction of the hot pressing roller, the width of the air outlet of the heating assembly is greater than or equal to the length of the hot pressing roller, so that all parts of the hot pressing roller are heated evenly and the temperature consistency of all parts of the hot pressing roller is maintained.

[0013] In one embodiment, the device further includes a temperature sensor configured to detect the temperature of the hot-pressing roller. The temperature sensor detects the temperature of the hot-pressing roller in real time and feeds the detected temperature back to the control component. The control component is configured to control the heating parameters of the heating component based on the temperature of the hot-pressing roller fed back by the temperature sensor, thereby maintaining the temperature of the hot-pressing roller at a predetermined temperature.

[0014] In one embodiment, a hot pressing drive is further included, connected to the hot pressing roller; the hot pressing drive is configured to drive the hot pressing roller to move toward or away from the pole piece, thereby automatically adjusting the distance between the hot pressing roller and the pole piece.

[0015] In one embodiment, the hot pressing roller mechanism includes two hot pressing rollers, one located on either side of the electrode, each of which is provided with the heating assembly, the hot pressing driver, and the temperature sensor. The two hot pressing rollers are located on opposite sides of the electrode's transport path, with one hot pressing roller on each opposing side of the electrode to heat-press the tape on the electrode surface, ensuring a more consistent fit between the tape and the electrode.

[0016] In one embodiment, the two hot pressing rollers are symmetrically arranged to press the electrode from both sides to keep the tape at each location of the electrode in close contact with the electrode.

[0017] In order to solve the above technical problems, the second aspect of the present application provides a pressing roller mechanism, including a cold pressing roller mechanism and a hot pressing roller mechanism; the cold pressing roller mechanism is configured to perform preliminary extrusion on the electrode after tape is applied; the hot pressing roller mechanism is arranged downstream of the cold pressing roller mechanism; the hot pressing roller mechanism is configured to perform hot pressing on the electrode after preliminary extrusion; the hot pressing roller mechanism is the hot pressing roller mechanism described in any one of the above items.

[0018] The cold pressing roller mechanism is used to perform preliminary squeezing on the electrode after tape application, smoothing and compacting the tape on the electrode surface, thereby improving the tightness of the fit between the tape and the electrode. The hot pressing roller mechanism further smoothes and compacts the tape on the electrode surface, thereby strengthening the tightness of the fit between the tape and the electrode.

[0019] In one embodiment, a preheating component is further included; along the transmission path of the electrode, the preheating component is located between the cold pressing roller mechanism and the hot pressing roller mechanism; the preheating component is configured to preheat the tape on the initially extruded electrode to soften the tape and improve the flexibility of the adhesive.

[0020] In one embodiment, the preheating assembly includes a hot air blowing assembly, which includes a hot air blowing gun and a hot air blowing gun cover, wherein the hot air blowing gun cover is disposed at the end of the hot air blowing gun near the electrode. The preheating assembly has a simple structure, low cost, and can achieve a good preheating effect.

[0021] In one embodiment, the angle between the air outlet direction of the hot air blowing assembly and the transmission direction of the electrode is 80 degrees to 100 degrees, which improves the heat utilization rate of the hot air blown out by the hot air blowing gun and has a good preheating effect on the tape on the electrode.

[0022] In one embodiment, the cold press roller mechanism includes a cold press drive and a cold press roller. The cold press drive is connected to the cold press roller and is configured to drive the cold press roller toward or away from the electrode sheet. By controlling the cold press drive, the cold press roller exerts a pressing force on the electrode sheet, thereby automatically adjusting the distance between the cold press roller and the electrode sheet.

[0023] In one embodiment, the pressing roller mechanism includes two hot pressing rollers, two cold pressing rollers, and two preheating assemblies. The two hot pressing rollers, two cold pressing rollers, and two preheating assemblies are respectively arranged on both sides of the electrode. A cold pressing roller is provided on opposite sides of the electrode to pre-press the tape on the electrode surface, and a preheating assembly is provided on opposite sides of the electrode to preheat the tape on the electrode surface. A hot pressing roller is provided on opposite sides of the electrode to heat-press the tape on the electrode surface, thereby ensuring a better fit between the tape and the electrode.

[0024] In one embodiment, the two hot pressing rollers are axially symmetrically arranged; and / or, the two cold pressing rollers are axially symmetrically arranged; and / or, the two preheating assemblies are axially symmetrically arranged, squeezing each part of the electrode from both sides to keep the tape at each part of the electrode tightly fitted to the electrode.

[0025] In order to solve the above technical problems, the third aspect of the present application provides a glue application device, including any one of the pressure roller mechanisms described above, which has at least the same advantages as the pressure roller mechanism.

[0026] In one embodiment, the device further includes a control assembly, to which the hot pressing roller mechanism, the cold pressing roller mechanism, and the preheating assembly are each connected. The control assembly is configured to control the distance between the hot pressing roller of the hot pressing roller mechanism and the electrode piece, the temperature of the hot pressing roller, the distance between the cold pressing roller of the cold pressing roller mechanism and the electrode piece, and the heating temperature of the preheating assembly. The control assembly automatically smoothes and compacts the electrode piece after adhesive lamination, thereby enhancing the tightness of the adhesive tape to the electrode piece and improving the adhesive lamination yield.

[0058] In order to make the purpose, technical solution and effect of this application clearer and more specific, the following embodiments of the technical solution of this application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of this application and are therefore only examples and are not intended to limit the scope of protection of this application.

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0060] In the description of the embodiments of the present application, the technical terms "first" and "second" are used only to distinguish different objects and should not be understood as indicating or implying relative importance or implicitly indicating the quantity, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the term "multiple" refers to more than two (including two), similarly, "multiple groups" refers to more than two (including two), and "multiple pieces" refers to more than two (including two), unless otherwise clearly and specifically defined.

[0061] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0062] In the description of the embodiments of this application, the term "and / or" is simply a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0063] Amounts, ratios, and other numerical values ​​are presented herein in a range format. It should be understood that such range format is used for convenience and brevity and should be interpreted flexibly to include not only the values ​​explicitly specified as range limits, but also all individual values ​​or sub-ranges encompassed within the range, as if each value and sub-range were explicitly specified.

[0064] Batteries typically include power lithium batteries and energy storage batteries. The manufacturing process for battery electrodes typically involves coating the current collector with active material slurry to form a large roll. This roll is then pre-slit into single-film rolls. Finally, the single-film rolls are die-cut and slit into smaller rolls. After die-cutting and slitting, the electrodes are wound to form a bare cell.

[0065] Die cutting is usually done with a rolling cutter. The cutters are divided into upper and lower cutters. The upper and lower cutters interlock (0.5mm-1.5mm) and are close to each other. The upper and lower cutters rotate synchronously in opposite directions. The pole pieces are sheared (with some scoring) through the interlocking area of ​​the upper and lower cutters.

[0066] Because the upper and lower cutters interlock and engage closely with each other, wear and tear at the interlocking areas causes the blades to become blunt or chipped. In the actual battery cell manufacturing process, it is necessary to cope with different material formulations and process requirements. The different working conditions of thick or thin coatings on the pole pieces will all lead to metal burrs on the cutting edges. Excessive metal burrs on the cutting edges can pierce the diaphragm after the battery cell is formed, causing an internal short circuit in the battery cell. For example, the tabs of the pole pieces are formed by laser cutting, slicing metal, and cutting with a cutter; the cutting process produces a metal heat-affected zone and metal wiredrawing, which affects the safety of the battery.

[0067] Therefore, it is necessary to apply glue to the edges of the die-cut electrode sheets, and the adhesive film can safely isolate the metal burrs on the edges of the electrode sheets. In view of this, the present application provides a hot pressing roller mechanism, a pressing roller mechanism, a gluing device, and a battery production system to automate the entire gluing process and improve the gluing yield.

[0068] It should be noted that the gluing device provided in the embodiments of the present application is suitable for die-cutting and slitting equipment, and can be linked with the die-cutting and slitting equipment to achieve pole piece gluing, with the advantages of fast gluing efficiency, accurate gluing position, controllable gluing speed, and continuous and stable gluing. The hot pressing roller mechanism, pressing roller mechanism, gluing device, and battery production system provided in the embodiments of the present application are not limited to gluing pole pieces after die-cutting, but can also be used for die-cutting after gluing, and can also be used for gluing in other processes in the battery production process.

[0069] Please refer to FIG. 1 a , which is a schematic structural diagram of a glue application device provided in an embodiment of the present application.

[0070] The gluing device 1000 provided in the embodiment of the present application includes a support mechanism 100 and a gluing mechanism 200. The gluing device 1000 is configured to glue a pole piece; optionally, the gluing device 1000 is configured to glue an edge of a pole piece.

[0071] The support mechanism 100 has an inlet A and an outlet B. These define the electrode transfer path. Specifically, the electrode is in the form of an elongated strip, and is transferred from the inlet A to the outlet B. The inlet A refers to the entrance of the electrode into the gluing device 1000, while the outlet B refers to the exit of the electrode outside the operating range of the gluing device 1000. The elongated shape refers to the length of the electrode being much greater than its width.

[0072] In one embodiment, the support mechanism 100 includes a support plate 101 , which is a structural member that supports and positions the poles. Optionally, the support plate 101 is perpendicular to the ground, the pole pieces are parallel to the ground, and the direction of pole piece transmission is perpendicular to the support plate 101 .

[0073] The gluing mechanism 200 is disposed on the supporting mechanism 100 and is located on at least one side of the transmission path of the electrode piece. The gluing mechanism 200 is configured to apply glue to one surface of the electrode piece.

[0074] In one embodiment, the gluing device 1000 includes a gluing mechanism 200 located on one side of the electrode transport path and applying glue to the edge or entire surface of one surface of the electrode. Optionally, the gluing mechanism 200 applies glue to the edge of one surface of the electrode. By using the gluing mechanism 200 to apply glue to the electrode, the automation and efficiency of electrode gluing are improved, thereby increasing production capacity. Furthermore, the adhesive film formed on the electrode covers the burrs on the cross-section of the electrode after slitting, providing safety and isolation, thereby improving battery performance.

[0075] In one embodiment, the gluing device 1000 includes two gluing mechanisms 200, which are respectively arranged on opposite sides of the transmission path of the electrode, and glue the edges or the entire surface of the two opposite surfaces of the electrode respectively to reduce the impact of burrs on the edge of the electrode on battery performance.

[0076] In a specific embodiment, the two gluing mechanisms 200 are both used to glue the edges of the long sides of the electrode. The electrode is in the shape of an elongated strip and includes a first surface and a second surface arranged opposite to each other. The two gluing mechanisms 200 are respectively defined as a first gluing mechanism and a second gluing mechanism, the first gluing mechanism glues the long edges of the first surface of the electrode, and the second gluing mechanism glues the long edges of the second surface of the electrode; along the width direction of the electrode, the edges of the first surface of the electrode and the edges of the second surface of the electrode can be on the same side or on opposite sides. For example, when there are burrs on both sides of the length direction of the electrode, the first gluing mechanism can be used to glue the long edges of the first surface of the electrode, and the second gluing mechanism can be used to glue the long edges of the second surface of the electrode, and the long edges of the first surface of the electrode to be glued and the long edges of the second surface of the electrode to be glued are arranged opposite to each other, so as to achieve glue isolation and safety protection for the burrs on both sides of the electrode. As another example, a first gluing mechanism is used to glue the long side edge of the first surface of the pole piece, and a second gluing mechanism is used to glue the long side edge of the second surface of the pole piece, and the long side edge of the first surface of the pole piece to be glued and the long side edge of the second surface of the pole piece to be glued are on the same side, and the burrs on one side edge of the pole piece are double-glued for isolation and safety protection, thereby further reducing the impact of the burrs on the edge of the pole piece on the battery performance.

[0077] It should be noted that when a gluing mechanism 200 is provided on opposite sides of the electrode transmission path, the structures of the two gluing mechanisms 200 can be identical. For example, when the gluing device 1000 is in operation, the electrode is transported horizontally, and the two gluing mechanisms 200 are mirror-imaged and disposed on the upper and lower sides of the electrode transmission path.

[0078] The glue laminating mechanism 200 includes a feeding mechanism 210 and a receiving mechanism 220. The feeding mechanism 210 is configured to unwind the adhesive tape 701. The receiving mechanism 220 is configured to rewind the release film 7013 of the adhesive tape 701. The adhesive tape 701 includes a substrate film 7011, an adhesive film 7012 and a release film 7013 stacked in sequence (as shown in FIG1b , FIG1b is a structural schematic diagram of the adhesive tape 701 provided in an embodiment of the present application), and the release film 7013 is configured to protect the adhesive film 7012. After the adhesive tape 701 is attached to the electrode, the adhesive film 7012 contacts the electrode. By setting the feeding mechanism 210 to unwind the adhesive tape 701 and the receiving mechanism 220 to rewind the release film 7013, the occupied space of the glue laminating device 1000 is reduced, the space utilization rate is improved, and the entire glue laminating process is automated. By rolling up the release film 7013 of the tape 701 through the material receiving mechanism 220 , the collection efficiency of the release film 7013 by the gluing device 1000 during the electrode gluing process can be improved.

[0079] The gluing mechanism 200 further includes a control component (not shown), and the unloading mechanism 210 and the rewinding mechanism 220 are respectively connected to the control component. The control component controls the unloading mechanism 210 to unload and the rewinding mechanism 220 to rewind, thereby realizing automatic gluing.

[0080] Please refer to Figures 2 and 3. Figure 2 is a partial structural diagram of the unloading mechanism of the glue-applying mechanism shown in Figure 1a, and Figure 3 is a structural decomposition diagram of the unloading reel and the unloading fixed shaft of the unloading mechanism shown in Figure 2.

[0081] As shown in FIG. 2 , the unloading mechanism 210 includes a unloading component 211 , a winding tray 212 , a first deviation correction detection component 213 , and a deviation correction drive component 214 .

[0082] The unwinding assembly 211 includes an unwinding motor 2111. The winding disc 212 includes an unwinding reel 2121 and a tape roll 700 staggeredly wound on the unwinding reel 2121. The unwinding reel 2121 is connected to the unwinding motor 2111 and rotates under the drive of the unwinding motor 2111.

[0083] The unwinding motor 2111 is a structural component that provides driving force to the unwinding reel 2121. Exemplarily, the unwinding motor 2111 is a servo motor. The unwinding motor 2111 is connected to a control component that is configured to control the operation of the unwinding motor 2111 to provide driving force to the unwinding reel 2121.

[0084] The unwinding reel 2121 is a structural member that provides a winding space for the tape roll 700. Specifically, the side of the unwinding reel 2121 is provided with an annular winding groove 2121a. The annular winding groove 2121a refers to a groove body formed end to end along the circumference of the side of the unwinding reel 2121. The unwinding reel 2121 is a cylindrical structure. The groove depth of the annular winding groove 2121a is the same at all locations, forming a circular annular winding groove 2121a. The annular winding groove 2121a has no sharp edges. This reduces the possibility of damaging the tape 701 during the process of winding the tape roll 700 onto the annular winding groove 2121a of the unwinding reel 2121 or releasing the tape 701 from the tape roll 700 in the annular winding groove 2121a. The tape 701 of the tape roll 700 is spirally wound in the annular winding groove 2121a to form a multi-layer structure. Adjacent layers of adhesive tape 701 are staggered, and adhesive tape 701 within the same layer is also staggered, forming an offset tape roll 700 wound on the unwinding reel 2121. This increases the length of adhesive tape 701 that can be accommodated by the annular roll groove 2121a. Optionally, when the depth of the annular roll groove 2121a is constant, the width of the annular roll groove 2121a is 10 mm to 100 mm, and the width of the adhesive tape 701 is 3 mm to 20 mm, the annular roll groove 2121a can accommodate a length of adhesive tape 701 greater than 5000 m.

[0085] The unwinding assembly 211 also includes a fixed unwinding shaft 2112, a synchronous unwinding wheel 2113, a drive wheel 2114, and a synchronous belt 2115. The unwinding reel 2121 is sleeved onto the fixed unwinding shaft 2112. The synchronous unwinding wheel 2113 is attached to one end of the fixed unwinding shaft 2112; that is, the end of the fixed unwinding shaft 2112 is connected to the synchronous unwinding wheel 2113. The drive wheel 2114 is connected to the synchronous unwinding wheel 2113 via the synchronous belt 2115. The unwinding motor 2111 is connected to the drive wheel 2114, driving the fixed unwinding shaft 2112 to rotate via the drive wheel 2114 and the synchronous unwinding wheel 2113. Among them, the unloading fixed shaft 2112 refers to the structural component that drives the unloading reel 2121 to rotate; the unloading driving wheel 2114 refers to the structural component that is directly connected and directly driven by the unloading motor 2111; the unloading synchronous belt 2115 refers to the structural component that enables the unloading synchronous wheel 2113 and the unloading driving wheel 2114 to be synchronously transmitted; the unloading synchronous wheel 2113 refers to the structural component that drives the unloading fixed shaft 2112 and the unloading driving wheel 2114 to rotate synchronously.

[0086] The unwinding motor 2111 provides driving force, driving the unwinding drive wheel 2114 to rotate. The unwinding synchronous wheel 2113, driven by the unwinding synchronous belt 2115, rotates along with the unwinding drive wheel 2114. The unwinding fixed shaft 2112, driven by the unwinding synchronous wheel 2113, rotates, thereby rotating the unwinding reel 2121 mounted on the unwinding fixed shaft 2112. The unwinding reel 2121 rotates to release the adhesive tape 701 wrapped around the unwinding reel 2121. Through the mutual cooperation between the unwinding motor 2111, the unwinding synchronous wheel 2113, the unwinding drive wheel 2114, the unwinding synchronous belt 2115, and the unwinding fixed shaft 2112, the unwinding motor 2111 drives the unwinding reel 2121 to rotate, and the rotation of the drive shaft of the unwinding motor 2111 and the rotation of the unwinding reel 2121 are well synchronized.

[0087] As shown in Figure 3, the unwinding reel 2121 includes a winding member 2121b, a first fixing plate 2121c, and a second fixing plate 2121d. The winding member 2121b is a cylindrical structure with an annular groove formed along its circumference, which serves as the annular winding groove 2121a. The first fixing plate 2121c and the second fixing plate 2121d are respectively disposed on opposite sides of the winding member 2121b. The unwinding fixed shaft 2112 sequentially passes through the second fixing plate 2121d, the winding member 2121b, and the first fixing plate 2121c. A fixing ring 2121e is provided on the side of the first fixing plate 2121c away from the second fixing plate 2121d. The fixing ring 2121e is sleeved onto the unwinding fixed shaft 2112 to secure the unwinding reel 2121 on the unwinding fixed shaft 2112.

[0088] The unloading mechanism 210 also includes a material detection sensor 2116, which is configured to detect the remaining amount of the tape roll 700. By providing the material detection sensor 2116, the remaining amount of the tape roll 700 can be monitored in real time, allowing for timely detection of when the tape roll 700 is about to run out or exhausted, facilitating the issuance of a timely alarm. This significantly reduces the probability of the electrode being glued through the gluing device, thereby improving the gluing yield. Optionally, the material detection sensor 2116 is a photoelectric sensor that can monitor the remaining material in real time. A photoelectric sensor is a component that converts optical signals into electrical signals. Optionally, the unloading mechanism 210 also includes an alarm (not shown) connected to the material detection sensor 2116. When the material detection sensor 2116 detects that the remaining amount of the tape roll 700 is less than or equal to a threshold, the alarm emits at least one of an audible, visual, or electrical alarm. The control component is configured to control the alarm to emit an alarm based on the detection structure of the material detection sensor 2116.

[0089] The first deviation correction detection component 213 is configured to detect the position deviation of the tape 701 released by the unwinding component 211 when it is separated from the tape roll 700; in other words, the first deviation correction detection component 213 is configured to detect the position deviation of the tape 701 released by the unwinding motor 2111 driving the unwinding reel 2121 to rotate when it is separated from the tape roll 700.

[0090] The deflection correction drive assembly 214 is connected to the unwinding reel 2121 ; the deflection correction drive assembly 214 is configured to drive the unwinding reel 2121 to move axially according to the position offset of the tape 701 when it is separated from the tape roll 700 , so as to correct the deflection of the tape 701 .

[0091] The first deflection correction detection component 213 and the deflection correction drive component 214 are respectively connected to the control component. The control component is configured to receive the position deviation of the adhesive tape 701 when it is separated from the adhesive tape roll 700 detected by the first deflection correction detection component 213, and control the deflection correction drive component 214 to drive the unwinding reel 2121 to move axially according to the position deviation of the adhesive tape 701 when it is separated from the adhesive tape roll 700, so as to correct the deflection of the adhesive tape 701.

[0092] Since the tape roll 700 is staggered and wound on the unwinding reel 2121 , the position of the released tape 701 will continuously swing along the axial direction of the unwinding reel 2121 when it is separated from the tape roll 700 .

[0093] The transmission path of the adhesive tape 701 after it is released from the unloading reel 2121 and corresponding to the transmission path of the pole piece is defined as a preset path. The first deviation correction detection component 213 detects whether the transmission path of the adhesive tape 701 released from the unloading reel 2121 is consistent with the preset path. If not, the deviation correction drive component 214 drives the unloading reel 2121 to move in the opposite axial direction of the unloading reel 2121 according to the offset direction and offset amount of the transmission path of the adhesive tape 701 detected by the first deviation correction detection component 213 and the preset path to compensate, that is, the unloading reel 2121 is driven to move in the opposite axial direction of the offset by a corresponding offset amount, thereby correcting the deviation of the adhesive tape 701, accurately controlling the consistency of the transmission path of the adhesive tape 701 released from the unloading reel 2121, and aligning the unwinding of the adhesive tape 701. Specifically, the control component controls the deviation correction drive component 214 to drive the unloading reel 2121 to move in the opposite axial direction of the offset by a corresponding offset amount.

[0094] In one embodiment, the correction drive assembly 214 drives the unwinding reel 2121 to move axially with an amplitude greater than or equal to the width of the tape 701, so that the tape 701 wound on the unwinding reel 2121 at different axial positions along the unwinding reel 2121 can be aligned with the preset path after being released, and the tape 701 wound on the unwinding reel 2121 can be fully unwound.

[0095] The deflection correction drive assembly 214 includes a base 2141, a guide rail 2142, a slider 2143, and a deflection correction motor 2144. The deflection correction motor 2144 is connected to the control assembly to drive the unwinding reel 2121 to move axially to correct the deflection of the tape 701. The first deflection correction detection assembly 213 is arranged on the deflection correction drive assembly 214; optionally, the first deflection correction detection assembly 213 is arranged on the base 2141. The position of the first deflection correction detection assembly 213 is fixed to detect whether the tape 701 is offset at the same position. The guide rail 2142 is arranged on the base 2141. The slider 2143 is slidably arranged on the guide rail 2142, and the slider 2143 is connected to the unwinding assembly 211. The deflection correction motor 2144 is arranged on the base 2141, and the deflection correction motor 2144 is connected to the slider 2143. The deflection correction motor 2144 drives the unwinding assembly 211 via the slider 2143, thereby driving the unwinding reel 2121 in axial motion. The base 2141 supports the slider 2143; the guide rail 2142 guides the movement of the slider 2143; the slider 2143 moves relative to the base 2141 and is connected to the unwinding assembly 211; and the deflection correction motor 2144 provides the driving force for the slider 2143. The base 2141, guide rail 2142, slider 2143, and deflection correction motor 2144 work together to drive the unwinding reel 2121 in axial motion, maintaining the unwinding alignment of the adhesive tape 701.

[0096] The adhesive tape 701 is misaligned and wound around the unwinding reel 2121. The first deflection detection assembly 213 detects that the adhesive tape 701 has deviated from the position where it leaves the tape roll 700. The control assembly then activates the deflection correction motor 2144, which in turn drives the slider 2143, which in turn drives the unwinding assembly 211. This allows the unwinding reel 2121 to move along its own axis, precisely controlling its position and achieving precise unwinding of the tape. A closed loop is formed between the first deflection detection assembly 213 and the deflection correction motor 2144, ensuring that the unwinding of the adhesive tape 701 is aligned with the preset path and that the unwinding position of the adhesive tape 701 is consistent.

[0097] In one embodiment, a groove extending along a straight line is formed on the base 2141 , and the groove serves as the guide rail 2142 . The slider 2143 is provided with a protrusion corresponding to the groove, and the protrusion is embedded in the groove and slides.

[0098] In one embodiment, a protrusion extending in a straight line is formed on the base 2141 , and the protrusion serves as the guide rail 2142 . The slider 2143 is provided with a sliding groove corresponding to the protrusion, and the sliding groove is clamped on the protrusion and slides.

[0099] In one embodiment, the correction motor 2144 is a servo motor.

[0100] The correction drive assembly 214 also includes a first motor coupling 2145 and a first screw rod 2146. The correction motor 2144 is connected to the first screw rod 2146 via the first motor coupling 2145. The slider 2143 is sleeved on the first screw rod 2146. The driving force of the correction motor 2144 is transmitted to the slider 2143 via the first motor coupling 2145 and the first screw rod 2146, driving the slider 2143 to slide along the first screw rod 2146. The first motor coupling 2145 refers to a structural component that connects the correction motor 2144 and the first screw rod 2146, allowing the drive shaft of the correction motor 2144 to rotate with the screw rod to transmit torque; the first screw rod 2146 refers to a structural component that converts rotational motion into linear motion, thereby causing the slider 2143 to move in a straight line.

[0101] The deviation correction drive assembly 214 also includes two first sensors 2147, and the two first sensors 2147 are spaced apart on the base 2141. The slider 2143 slides between the two first sensors 2147. Optionally, the first sensor 2147 is a photoelectric sensor, wherein a photoelectric sensor refers to a structural component that converts an optical signal into an electrical signal. The first sensor 2147 is configured to control the maximum movement of the slider 2143, and further achieve precise control of the consistency of the transmission path of the tape 701 released from the unwinding reel 2121, so that the unwinding of the tape 701 is aligned with the preset path. The first sensor 2147 is used to detect the movement amplitude of the slider 2143 to achieve control of the movement amplitude of the slider 2143, which is conducive to improving the degree of automation and improving the glue application efficiency. The first sensor 2147 is connected to the control assembly.

[0102] Continuing with FIG2 , the unwinding mechanism 210 further includes an unwinding connection block 2117, a bearing rod 2118, and a bearing seat 2119. The unwinding connection block 2117 connects the unwinding reel 2121 and the slider 2143, respectively. The bearing rod 2118 is connected to the unwinding connection block 2117. The bearing seat 2119 is sleeved on the bearing rod 2118. The sliding of the slider 2143 drives the unwinding reel 2121 along its axis via the unwinding connection block 2117 and the bearing rod 2118, causing the unwinding reel 2121 to move along a straight line. The unwinding connection block 2117 is a structural component that enables the unwinding reel 2121 to move synchronously with the slider 2143; the bearing rod 2118 is a structural component that guides the movement of the unwinding reel 2121; and the bearing seat 2119 is a structural component that secures the bearing rod 2118.

[0103] Please refer to Figures 4 and 5. Figure 4 is a structural schematic diagram of the correcting guide wheel assembly and the positioning guide wheel assembly of the discharge mechanism shown in Figure 1a, and Figure 5 is a decomposition structural schematic diagram of the correcting guide wheel assembly shown in Figure 4.

[0104] In one embodiment, the unloading mechanism 210 further includes a plurality of deflection correction guide wheel assemblies 215 and a plurality of positioning guide wheel assemblies 216. The deflection correction guide wheel assemblies 215 and the positioning guide wheel assemblies 216 are both located downstream of the transmission path of the adhesive tape 701 released from the adhesive tape roll 700 of the unloading reel 2121. The plurality of deflection correction guide wheel assemblies 215 and the plurality of positioning guide wheel assemblies 216 are arranged sequentially along the transmission path of the adhesive tape 701; that is, the adhesive tape 701 passes through the plurality of deflection correction guide wheel assemblies 215 before passing through the plurality of positioning guide wheel assemblies 216. The deflection correction guide wheel assemblies 215 and the positioning guide wheel assemblies 216 cooperate to correct the deviation of the adhesive tape 701 during transmission. The deflection correction guide wheel assemblies 215 and the positioning guide wheel assemblies 216 are structural components that guide the transmission of the adhesive tape 701.

[0105] The circumferential side surface of the correcting guide wheel assembly 215 has an annular limiting groove 2150; the annular limiting groove 2150 refers to the area on the correcting guide wheel assembly 215 where the tape 701 is provided. Specifically, the correcting guide wheel assembly 215 includes a support shaft 2151, a bearing 2152, two adjustment rings 2153, and a limiting member 2154. The side surface of the support shaft 2151 has a limiting portion 2151a. The bearing 2152 is mounted on the support shaft 2151. The limiting portion 2151a limits the position of the bearing 2152 on the support shaft 2151. The two adjustment rings 2153 and the bearing 2152 cooperate to define the annular limiting groove 2150. Two adjustment rings 2153 are spaced apart and mounted on the bearing 2152, with the spacing adjustable. This allows the width of the annular retaining groove 2150 to accommodate tapes 701 of varying widths. Alternatively, the widths of the annular retaining grooves 2150 of different guide wheel assemblies 215 can be varied to accommodate the swing amplitude of the tape 701 at different locations along the transmission path. A retaining member 2154 is disposed on the support shaft 2151, located on the side of the bearing 2152 away from the retaining portion 2151a. The spacing between the retaining member 2154 and the retaining portion 2151a is adjustable, thereby adjusting the maximum axial swing amplitude of the bearing 2152 on the support shaft 2151 to accommodate the swing amplitude of the tape 701 at different locations along the transmission path. Furthermore, by providing the retaining member 2154 on the side of the bearing 2152 away from the retaining portion 2151a, the bearing 2152 is maintained securely mounted on the support shaft 2151, preventing it from falling off.

[0106] Optionally, support shaft 2151 includes a first cylindrical body 2151b and a second cylindrical body 2151c that are interconnected and coaxially arranged. The radius of first cylindrical body 2151b is greater than the radius of second cylindrical body 2151c. Because the radius of first cylindrical body 2151b is different from the radius of second cylindrical body 2151c, a stopper 2151a is formed at the connection between first cylindrical body 2151b and second cylindrical body 2151c. When bearing 2152 is sleeved on support shaft 2151, the end of bearing 2152 abuts against the end face of first cylindrical body 2151b adjacent to second cylindrical body 2151c, thereby limiting the position of bearing 2152.

[0107] The circumferential side surface of the positioning guide wheel assembly 216 has an annular limiting groove; this annular limiting groove is the area on the positioning guide wheel assembly 216 where the adhesive tape 701 is disposed. Specifically, the positioning guide wheel assembly 216 includes a support shaft, a bearing, two adjustment rings, and a limiting member. The structure of the positioning guide wheel assembly 216 is similar to that of the correcting guide wheel assembly 215. For details on the structure of the correcting guide wheel assembly 215, please refer to the above description.

[0108] It can be understood that due to the limited accuracy of the correction work performed by the first correction detection component 213 and the correction drive component 214, the tape 701 released from the unwinding reel 2121 will swing along the axial direction of the unwinding reel 2121, and further correction will be performed by setting the correction guide wheel component 215; therefore, along the transmission path of the tape 701, from the unwinding reel 2121 to the first positioning guide wheel component 216, the swing amplitude of the tape 701 gradually decreases to maintain the unwinding alignment.

[0109] In one embodiment, the correcting guide wheel assembly 215 is configured to be able to swing along its own axis; the positioning guide wheel assembly 216 is configured to be fixed along its own axial position; the annular limit groove 2150 on the correcting guide wheel assembly 215 is the same width as the annular limit groove on the positioning guide wheel assembly 216; along the transmission path of the tape 701, the swing amplitude of multiple correcting guide wheel assemblies 215 gradually decreases, adapting to the swing amplitude trend of the tape 701, thereby achieving gradual correction of the transmission deviation of the tape 701, so that the position consistency of the tape 701 during the movement is high and the operation is stable, reducing the risk of the tape 701 breaking. The correcting guide wheel assembly 215 is configured to be able to swing along its own axis. This means that the annular limiting groove 2150 swings along the axis of the correcting guide wheel assembly 215. For example, the correcting guide wheel assembly 215 can swing along the axis of the support shaft 2151 between the limiting member 2154 and the limiting portion 2151a via the bearing 2152, with the distance between the two adjustment rings 2153 being constant. Exemplarily, the unloading mechanism 210 further includes multiple correcting guide wheel assemblies 215 and a positioning guide wheel assembly 216. The adhesive tape 701 passes through the multiple correcting guide wheel assemblies 215 before passing through the positioning guide wheel assembly 216. The swing amplitude of the multiple correcting guide wheel assemblies 215 gradually decreases along the conveyance path of the adhesive tape 701. If there are multiple positioning guide wheel assemblies 216, the multiple positioning guide wheel assemblies 216 are configured to be fixed along their own axial position. For example, the bearing 2152 of the positioning guide wheel assembly 216 cannot swing between the limit member 2154 and the limit portion 2151a along the axial direction of the support shaft 2151 on the support shaft 2151.

[0110] In one embodiment, the positioning guide wheel assembly 216 is configured to be fixed along its own axial position; the correcting guide wheel assembly 215 is configured to be fixed along its own axial position; the center of the annular limit groove of the positioning guide wheel assembly 216 is aligned with the center of the annular limit groove of the correcting guide wheel assembly 215; along the transmission path of the tape 701, the width of the annular limit grooves of several correcting guide wheel assemblies 215 and several positioning guide wheel assemblies 216 gradually decreases, adapting to the swing amplitude trend of the tape 701, thereby achieving the correction of the transmission deviation of the tape 701, so that the position consistency of the tape 701 during the movement is high and the operation is stable, reducing the risk of the tape 701 breaking. Exemplarily, the unloading mechanism 210 further includes multiple deflection correction guide wheel assemblies 215 and a positioning guide wheel assembly 216. The adhesive tape 701 passes through the multiple deflection correction guide wheel assemblies 215 before passing through the positioning guide wheel assembly 216. The widths of the annular limiting grooves 2150 of the multiple deflection correction guide wheel assemblies 215 gradually decrease along the conveying path of the adhesive tape 701. The width of the annular limiting groove of the positioning guide wheel assembly 216 decreases relative to the width of the annular limiting groove 2150 of the last deflection correction guide wheel assembly 215 that the adhesive tape 701 passes through. If there are multiple positioning guide wheel assemblies 216, the annular limiting grooves of the multiple positioning guide wheel assemblies 216 have the same width.

[0111] By arranging a correction guide wheel assembly 215 and a positioning guide wheel assembly 216 downstream of the release transmission path of the tape roll 700 of the unwinding reel 2121, the deviation of the tape 701 released by the unwinding reel 2121 can be corrected, so that the position consistency of the tape 701 released by the unwinding mechanism 210 is high and the operation is stable, thereby improving the accuracy of subsequent glue positioning and reducing the risk of the tape 701 breaking.

[0112] The unwinding mechanism 210 realizes the precise unwinding of the shaft-type tape, and the deviation-correcting guide wheel assembly 215 and the positioning guide wheel assembly 216 cooperate with the unwinding to improve the diagonal accuracy of the unwinding tape.

[0113] Please refer to FIG6 , which is a partial structural diagram of the material receiving mechanism of the gluing mechanism shown in FIG1 a .

[0114] The material receiving mechanism 220 includes a material receiving assembly 221 , a material receiving reel 222 and a dislocation driving assembly 223 .

[0115] The take-up reel 222 is a structural component that provides winding space for the release film 7013 of the adhesive tape 701. Specifically, the take-up reel 222 has an annular take-up groove 2220; the annular take-up groove 2220 refers to a groove body formed end to end along the circumference of the side of the take-up reel 222. The take-up reel 222 is a cylindrical structure, and the groove depth of the annular take-up groove 2220 is uniform at all locations, forming a circular annular take-up groove 2220. The release film 7013 of the adhesive tape 701 is spirally wound within the annular take-up groove 2220 to form a multi-layer structure. Adjacent layers of release film 7013 are staggered, and the release film 7013 of the adhesive tape 7013 on the same layer is also staggered. In other words, the release film 7013 is staggered around the take-up reel 222, increasing the length of release film 7013 that the annular take-up groove 2220 can accommodate.

[0116] The take-up reel 222 includes a rotating shaft 2221 and two take-up reels 2222, one located at each end of the rotating shaft 2221. The rotating shaft 2221 is cylindrical, and the take-up reels 2222 are disc-shaped. The take-up reels 2222 are coaxial with the rotating shaft 2221, and their diameter is larger than that of the rotating shaft 2221. The two take-up reels 2222 and the rotating shaft 2221 define an annular take-up groove 2220. The take-up reel 2222 also includes a fixing member 2223, located on the side of one take-up reel 2222 facing away from the other take-up reel 2222, to securely position the take-up reels 2222 on the rotating shaft 2221.

[0117] The rewinding assembly 221 includes a rewinding motor 2211. The rewinding reel 222 is connected to the rewinding motor 2211 and rotates under the drive of the rewinding motor 2211. The rewinding motor 2211 is a structural component that provides driving force to the rewinding reel 222; illustratively, the rewinding motor 2211 is a servo motor. The rewinding motor 2211 is connected to a control assembly, which is configured to control the operation of the rewinding motor 2211 to provide driving force to the rewinding reel 222.

[0118] The rewinding assembly 221 also includes a rewinding fixed shaft 2212, a rewinding synchronous wheel 2213, a rewinding drive wheel 2214, and a rewinding synchronous belt 2215. The rewinding reel 222 is sleeved onto the rewinding fixed shaft 2212. The rewinding synchronous wheel 2213 is attached to one end of the rewinding fixed shaft 2212; that is, the end of the rewinding fixed shaft 2212 is connected to the rewinding synchronous wheel 2213. The rewinding drive wheel 2214 is connected to the rewinding synchronous wheel 2213 via the rewinding synchronous belt 2215. The rewinding motor 2211 is connected to the rewinding drive wheel 2214, which drives the rewinding fixed shaft 2212 to rotate via the rewinding drive wheel 2214 and the rewinding synchronous wheel 2213. Among them, the material receiving fixed shaft 2212 refers to the structural component that drives the material receiving reel 222 to rotate; the material receiving drive wheel 2214 refers to the structural component that is directly connected and directly driven by the winding motor 2211; the material receiving synchronous belt 2215 refers to the structural component that enables the material receiving synchronous wheel 2213 and the material receiving drive wheel 2214 to be synchronously transmitted; the material receiving synchronous wheel 2213 refers to the structural component that drives the material receiving fixed shaft 2212 and the material receiving drive wheel 2214 to rotate synchronously.

[0119] The rewinding motor 2211 provides driving force, driving the rewinding drive wheel 2214 to rotate. The rewinding synchronous wheel 2213, driven by the rewinding synchronous belt 2215, rotates along with the rewinding drive wheel 2214. The rewinding fixed shaft 2212, driven by the rewinding synchronous wheel 2213, rotates, thereby rotating the rewinding reel 222 mounted on the rewinding fixed shaft 2212. The rotation of the rewinding reel 222 causes the release film 7013 of the adhesive tape 701 to be wound around the annular rewinding groove 2220 of the rewinding reel 222, thereby achieving rewinding. The coordination between the rewinding motor 2211, the rewinding synchronous wheel 2213, the rewinding drive wheel 2214, the rewinding synchronous belt 2215, and the rewinding fixed shaft 2212 enables the rewinding motor 2211 to drive the rewinding reel 222 to rotate, and the rotation of the drive shaft of the rewinding motor 2211 and the rotation of the rewinding reel 222 are well synchronized.

[0120] The offset drive assembly 223 is connected to the take-up reel 222 and is configured to drive the take-up reel 222 to move back and forth along its own axial direction. Specifically, the offset drive assembly 223 is connected to the take-up assembly 221 and drives the entire take-up assembly 221 and the take-up reel 222 to move together, thereby achieving back and forth movement of the take-up reel 222 along its own axial direction. The offset drive assembly 223 refers to a structural component that drives the take-up reel 222 to move along its own axial direction. Exemplarily, the offset drive assembly 223 includes a cylinder. The control assembly is configured to control the offset drive assembly 223 to drive the take-up reel 222 to move back and forth along its own axial direction.

[0121] By setting up an offset drive component 223 to drive the material receiving reel 222 to move back and forth along its own axis, the release film 7013 can be staggered and wound on the material receiving reel 222, which is conducive to achieving uniform distribution of the release film 7013 on the material receiving reel 222, realizing precise winding in a shaft-like manner, and increasing the length of the release film 7013 that can be accommodated by the annular winding groove 2220 of the material receiving reel 222.

[0122] In one embodiment, the offset drive component 223 drives the take-up reel 222 to move back and forth axially with an amplitude that is an integer multiple of and at least twice the width of the release film 7013 of the tape 701, so that at least two turns of the release film 7013 can be completely offset and wound on the take-up reel 222, which is beneficial to increasing the length of the release film 7013 that can be accommodated by the annular take-up groove 2220 of the take-up reel 222, reducing the frequency of cleaning the release film 7013 wound on the take-up reel 222, and strengthening the automated gluing process.

[0123] In one embodiment, the width of the annular winding groove 2220 is an integer multiple and at least twice the width of the release film 7013 of the tape 701, so that at least two turns of the release film 7013 can be completely staggered and wound on the take-up reel 222, which is beneficial to increasing the length of the release film 7013 that can be accommodated by the annular winding groove 2220 of the take-up reel 222, reducing the frequency of cleaning the release film 7013 wound on the take-up reel 222, and strengthening the automated gluing process.

[0124] In one embodiment, the receiving mechanism 220 further includes a substrate detection sensor 224 configured to detect the amount of release film 7013 wound on the receiving reel 222. The substrate detection sensor 224 enables real-time monitoring of the amount of release film 7013 wound on the receiving reel 222, allowing for timely detection of when the receiving reel 222 is about to be or has been fully wound with release film 7013. This facilitates the issuance of an alarm, significantly reducing the impact of the release film 7013 on the adhesive lamination process and improving adhesive lamination yield. Optionally, the receiving mechanism 220 further includes an alarm (not shown) connected to the substrate detection sensor 224. When the substrate detection sensor 224 detects that the amount of release film 7013 wound on the receiving reel 222 is greater than or equal to a threshold, the alarm emits at least one of an audible, visual, or electrical alarm. The control component is configured to control the alarm to emit an alarm based on the detection information of the substrate detection sensor 224.

[0125] In one embodiment, the material receiving mechanism 220 further includes a plurality of positioning guide wheel assemblies 216 and a plurality of deflection correction guide wheel assemblies 215 (see Figures 4 and 5). The deflection correction guide wheel assemblies 215 and the positioning guide wheel assemblies 216 are both located upstream of the transmission path of the release film 7013 of the material receiving reel 222. The plurality of positioning guide wheel assemblies 216 and the plurality of deflection correction guide wheel assemblies 215 are arranged sequentially along the transmission path of the release film 7013 of the adhesive tape 701; that is, the release film 7013 of the adhesive tape 701 passes through the plurality of positioning guide wheel assemblies 216 before passing through the plurality of deflection correction guide wheel assemblies 215. The deflection correction guide wheel assemblies 215 and the positioning guide wheel assemblies 216 are structural components that guide the transmission of the release film 7013. It can be understood that since the release film 7013 is staggered and wound on the take-up reel 222 , the swing amplitude of the release film 7013 gradually increases along the transmission path of the release film 7013 from the positioning guide wheel assembly 216 to the take-up reel 222 .

[0126] By arranging a correction guide wheel assembly 215 and a positioning guide wheel assembly 216 upstream of the transmission path of the release film 7013 of the receiving reel 222, the release film 7013 can be staggered and wound on the receiving reel 222 on the basis of high position consistency during the transmission process before entering the receiving mechanism 220, and the release film 7013 can be evenly distributed on the receiving reel 222.

[0127] The specific structures of the deviation correction guide wheel assembly 215 and the positioning guide wheel assembly 216 can be found in the specific structure introduction of the deviation correction guide wheel assembly 215 and the positioning guide wheel assembly 216 in the discharge mechanism 210, and will not be repeated here.

[0128] In one embodiment, the deflection correction guide wheel assembly 215 is configured to be able to swing along its own axis; the positioning guide wheel assembly 216 is configured to be fixed along its own axis; the annular limiting groove 2150 on the deflection correction guide wheel assembly 215 has the same width as the annular limiting groove on the positioning guide wheel assembly 216; and the swing amplitude of the multiple deflection correction guide wheel assemblies 215 gradually increases along the transmission path of the release film 7013 of the adhesive tape 701. Exemplarily, the receiving mechanism 220 further includes multiple deflection correction guide wheel assemblies 215 and one positioning guide wheel assembly 216. The release film 7013 of the adhesive tape 701 passes through the positioning guide wheel assembly 216 before passing through the multiple deflection correction guide wheel assemblies 215. Furthermore, along the transmission path of the release film 7013 of the adhesive tape 701, the swing amplitude of the multiple deflection correction guide wheel assemblies 215 gradually increases, adapting to the swing amplitude trend of the release film 7013. By performing the above-mentioned settings on the deviation correction guide wheel assembly 215 and the positioning guide wheel assembly 216, the position consistency of the release film 7013 of the tape 701 is high and the operation is stable during the transmission process before entering the receiving mechanism 220, thereby reducing the risk of the release film 7013 breaking, and the release film 7013 can be staggered and wound on the receiving reel 222.

[0129] In one embodiment, the positioning guide wheel assembly 216 is configured to be fixed along its own axial position; the correcting guide wheel assembly 215 is configured to be fixed along its own axial position; the center of the annular limiting groove of the positioning guide wheel assembly 216 is aligned with the center of the annular limiting groove of the correcting guide wheel assembly 215; along the transmission path of the release film 7013 of the tape 701, the width of the annular limiting grooves of several positioning guide wheel assemblies 216 and several correcting guide wheel assemblies 215 gradually increases. Exemplarily, the material receiving mechanism 220 also includes a plurality of deflection correction guide wheel assemblies 215 and a positioning guide wheel assembly 216. The tape 701 passes through the positioning guide wheel assembly 216 before passing through the plurality of deflection correction guide wheel assemblies 215. Along the transmission path of the release film 7013 of the tape 701, the width of the annular limiting groove 2150 of the plurality of deflection correction guide wheel assemblies 215 gradually increases, and the width of the annular limiting groove of the positioning guide wheel assembly 216 decreases relative to the width of the annular limiting groove 2150 of the first deflection correction guide wheel assembly 215 through which the release film 7013 of the tape 701 passes, which is adapted to the swing amplitude trend of the release film 7013. By performing the above-mentioned settings on the deviation correction guide wheel assembly 215 and the positioning guide wheel assembly 216, the position consistency of the release film 7013 of the tape 701 is high and the operation is stable during the transmission process before entering the receiving mechanism 220, thereby reducing the risk of the release film 7013 breaking, and the release film 7013 can be staggered and wound on the receiving reel 222.

[0130] Continuing with Figure 1a, the adhesive laminating mechanism 200 further includes a discharge oscillating roller assembly 230. The discharge oscillating roller assembly 230 is disposed along the transport path of the adhesive tape 701. It is located downstream of the discharge mechanism 210. The discharge oscillating roller assembly 230 is electrically connected to the unwinding motor 2111. The unwinding motor 2111 is configured to control the unwinding speed of the unwinding reel 2121 based on the tension feedback from the discharge oscillating roller assembly 230. Optionally, the discharge oscillating roller assembly 230 is configured to feed back the tension of the adhesive tape 701 released by the discharge assembly 211 to a control component. The control component is configured to receive the tension feedback from the discharge oscillating roller assembly 230 and, based on the feedback, control the driving force provided by the unwinding motor 2111 to the unwinding reel 2121, thereby controlling the unwinding speed of the unwinding reel 2121.

[0131] The unwinding roller assembly 230 is a structural component capable of detecting and providing feedback on the tension of the tape 701. By providing the unwinding roller assembly 230, the unwinding roller assembly 230 and the unwinding motor 2111 form a closed loop, controlling the transmission speed of the tape 701 throughout the entire gluing mechanism 200, maintaining smooth unwinding and facilitating optimal automated gluing results.

[0132] Please refer to FIG. 7 , which is a schematic structural diagram of the unwinding swing roller assembly of the gluing mechanism shown in FIG. 1 a .

[0133] The unwinding swing roller assembly 230 includes a tape positioning swing roller 231, a swing roller connecting block 232, a swing roller bearing seat 233, and a signal converter 234. The tape 701 passes over the tape positioning swing roller 231. The ends of the swing roller connecting block 232 are connected to the tape positioning swing roller 231 and the swing roller bearing seat 233, respectively. The signal converter 234 is connected to the swing roller bearing seat 233. The signal converter 234 is a device that converts angular or linear displacement into a signal form that can be communicated, transmitted, and stored. Optionally, the signal converter 234 is also connected to a control assembly.

[0134] The tape positioning swing roller 231 includes a first rubber roller 2311 and two first limiting plates 2312. The two first limiting plates 2312 are spaced apart and sleeved on the first rubber roller 2311. The two first limiting plates 2312 cooperate with the first rubber roller 2311 to define an annular receiving groove, in which the tape 701 is placed. When the tape 701 passes through the tape positioning swing roller 231, the tension of the tape 701 varies, and the pressing force on the tape positioning swing roller 231 varies, thereby causing the angle of the tape positioning swing roller 231 to change. In one embodiment, the tape positioning swing roller 231 can be a deviation correction guide wheel assembly 215.

[0135] The tape 701 passes over the tape positioning swing roller 231, causing the angle of the tape positioning swing roller 231 to change. The signal converter 234 detects the angle change of the tape positioning swing roller 231 through the swing roller bearing seat 233 and the swing roller connecting block 232, and feeds the angle change of the tape positioning swing roller 231 back to the control assembly. Based on this angle change information, the control assembly controls the unwinding motor 2111 to provide driving force to the unwinding reel 2121, forming a closed loop between the unwinding swing roller assembly 230 and the unwinding motor 2111.

[0136] Continuing to refer to FIG1a, the adhesive laminating mechanism 200 further includes a second deflection correction detection component 240. The second deflection correction detection component 240 is disposed on the transmission path of the adhesive tape 701 and is electrically connected to the control component. The second deflection correction detection component 240 is configured to detect the positional deviation of the adhesive tape 701 during transmission and provide feedback to the control component. The control component controls the deflection correction drive component 214 to drive the unwinding reel 2121 to move along its own axial direction based on the positional deviation of the adhesive tape 701 during transmission, so as to correct the deflection of the adhesive tape 701, accurately control the consistency of the transmission path of the adhesive tape 701 released from the unwinding reel 2121, and maintain the unwinding alignment of the adhesive tape 701.

[0137] The second deflection detection assembly 240 is located downstream of the unwinding mechanism 210. Optionally, the second deflection detection assembly 240 is located downstream of the unwinding swing roller assembly 230. The second deflection detection assembly 240, in addition to the first deflection detection assembly 213 in the unwinding mechanism 210, further improves the consistency of the transport path of the adhesive tape 701 released from the unwinding reel 2121, thereby facilitating the alignment of the unwinding of the adhesive tape 701.

[0138] Please refer to FIG8 , which is a schematic structural diagram of the second deviation-correcting detection component of the gluing mechanism shown in FIG1 a .

[0139] The second deviation correction detection component 240 includes a moving motor 241, a second motor coupling 242, an optical axis positioning column 243, a second screw rod 244, a signal feedback board 245, a tape sensor 246, a linear bearing 247, a second sensor 248, and a base 249.

[0140] The signal feedback plate 245 is a structural component that forms the tape detection area. A notch 2451 is provided on the signal feedback plate 245, which forms the detection area for the tape 701. Specifically, the signal feedback plate 245 is mounted on the linear bearing 247. A portion of the signal feedback plate 245 extends beyond the linear bearing 247, meaning that the orthographic projection of the signal feedback plate 245 on the linear bearing 247 is not covered by the linear bearing 247. The portion of the signal feedback plate 245 that extends beyond the linear bearing 247 is provided with a notch 2451.

[0141] The linear bearing 247 is mounted on the second screw rod 244 and can move back and forth with the rotation of the linearly extending second screw rod 244. The linear bearing 247 is a structural component that fixes the signal feedback plate 245 and can drive the signal feedback plate 245 to move back and forth along a straight line.

[0142] The second screw rod 244 is connected to the mobile motor 241 via the second motor coupling 242. One end of the second screw rod 244 passes through the base 249 and is connected to the second motor coupling 242; the other end of the second screw rod 244 is fixed to the base 249. When the tape 701 enters the vicinity of the notch 2451 (i.e., the tape detection area), the second screw rod 244 is driven to rotate by the mobile motor 241, which in turn drives the signal feedback plate 245 to move back and forth to confirm the detection position of the tape 701. The mobile motor 241 is connected to the control component, which is also configured to control the operation of the mobile motor 241.

[0143] The tape sensor 246 is located on the signal feedback plate 245 and is positioned adjacent to the notch 2451 on the signal feedback plate 245, i.e., adjacent to the tape detection area, to detect the deviation of the tape 701. The tape sensor 246 is a structural component that converts the detected deviation signal of the tape 701 into an electrical signal. The tape sensor 246 automatically detects the deviation position of the tape 701 during operation. The tape sensor 246 is also connected to the control assembly, which is further configured to receive the deviation detected by the tape sensor 246 and, based on the positional deviation feedback of the tape 701 during transport, control the deflection correction motor 2144 of the deflection correction drive assembly 214 to drive the unwinding reel 2121 along its own axis to correct the deflection of the tape 701. The tape sensor 246 and the deflection correction motor 2144 form a closed loop to maintain the alignment of the unwinding of the tape 701.

[0144] Two second sensors 248 are spaced apart on base 249. These sensors are configured to limit the range of motion of linear bearing 247. Linear bearing 247 moves between the two second sensors 248, improving the accuracy of detecting positional deviations during the transfer of tape 701 and maintaining the consistent position of tape 701. The second sensors 248 are connected to the control assembly. Optionally, the second sensors 248 are photoelectric sensors, which convert light signals into electrical signals.

[0145] Linear bearing 247 is also mounted on optical axis positioning column 243, which is parallel to second screw rod 244 and guides the movement of linear bearing 247. Optical axis positioning column 243 has two opposite ends fixed to base 249. Optionally, second deviation correction detection assembly 240 includes two optical axis positioning columns 243, with the line connecting the center points of the orthographic projections of the two optical axis positioning columns 243 and the second screw rod 244 on linear bearing 247 forming a triangle.

[0146] The base 249 is fixed on the supporting mechanism 100 , so that the entire second deviation correction detection assembly 240 is fixed on the supporting mechanism 100 .

[0147] Continuing to refer to FIG1a, the gluing mechanism 200 further includes a tension control mechanism 250, which is disposed on the transmission path of the adhesive tape 701. The tension control mechanism 250 is configured to adjust the tension of the adhesive tape 701 during transmission, thereby preventing the adhesive tape 701 from curling and winding during the gluing process, and achieving a better gluing effect.

[0148] The tension control mechanism 250 is located downstream of the unwinding mechanism 210 ; optionally, the tension control mechanism 250 is located downstream of the second deviation correction detection component 240 .

[0149] Please refer to FIG9 and FIG10 . FIG9 is a structural diagram of the tension control mechanism of the gluing mechanism shown in FIG1 a , and FIG10 is a structural diagram of the tension sensor of the gluing mechanism shown in FIG1 a .

[0150] The tension control mechanism 250 includes a tension control motor 251, a tension driving wheel 252, a tension synchronous belt 253, a tension synchronous wheel 254, a tension coupling 255, a tension bearing seat 256, a tension limit block 257, a tension connecting block 258, and a tension positioning swing roller 259.

[0151] The tension drive wheel 252 is connected to the drive shaft of the tension control motor 251 and rotates under the drive of the tension control motor 251. The tension synchronization wheel 254 rotates synchronously with the tension drive wheel 252 via the tension timing belt 253. The tension synchronization wheel 254 is fixed to the end of the tension coupling 255. The tension bearing seat 256 is mounted on the tension coupling 255. The ends of the tension connection block 258 are respectively connected to the tension coupling 255 and the tension positioning swing roller 259, and the tension connection block 258 is fixed to the tension bearing seat 256.

[0152] The tension control mechanism 250 includes two tension limiters 257, located above and below the tension connection block 258. These limit the swing amplitude of the tension connection block 258. The tension connection block 258 is connected to a tension positioning swing roller 259, thereby limiting the swing amplitude of the tension positioning swing roller 259. When the tension connection block 258 contacts the tension limiter 257 above the tension connection block 258, the adhesive tape 701 reaches its maximum tension limit position. When the tension connection block 258 contacts the tension limiter 257 below the tension connection block 258, the adhesive tape 701 reaches its minimum tension limit position.

[0153] Tension sensor 270 is configured to detect the tension of tape 701 and feed the detection results back to the control component. A tension sensor is a structural component that converts optical signals into electrical signals. Tension sensor 270 and tension control motor 251 are connected to the control component; the control component is configured to receive the detection results from tension sensor 270 and, based on the detection results fed back by tension sensor 270, control tension control motor 251 to drive the tension drive wheel 252 to rotate. This is then transmitted to the tension positioning swing roller 259 through tension timing belt 253, tension timing pulley 254, tension coupling 255, and tension connection block 258, causing the tension to swing. The swing of tension positioning swing roller 259 maintains the tension of tape 701 constant. Optionally, tension sensor 270 is positioned adjacent to tension positioning swing roller 259.

[0154] The tension sensor 270 includes a smooth tension detection portion 271, through which the tape 701 passes, thereby enabling the tension sensor 270 to detect the tension of the tape 701. The tension detection portion 271 has a cylindrical structure, which reduces the possibility of damaging the tape 701 during the tension detection process of the tension sensor 270.

[0155] In one embodiment, the tension control motor 251 includes a servo motor.

[0156] In one embodiment, the tension positioning swing roller 259 includes a second rubber roller 2591 and two second limiting plates 2592. The two second limiting plates 2592 are spaced apart and sleeved on the second rubber roller 2591. The two second limiting plates 2592 cooperate with the second rubber roller 2591 to define an annular receiving groove, in which the adhesive tape 701 is placed. In one embodiment, the tension positioning swing roller 259 can also be the deflection correction guide wheel assembly 215.

[0157] In one embodiment, the tension coupling 255 extends in a straight line.

[0158] In one embodiment, the tension connection block 258 is a rectangular parallelepiped structure.

[0159] 1a, the adhesive laminating mechanism 200 further includes a traction mechanism 260, which is disposed on the transmission path of the adhesive tape 701 and configured to pull the adhesive tape 701. By providing the traction mechanism 260, the transmission speed of the adhesive tape 701 can be controlled.

[0160] The traction mechanism 260 is arranged downstream of the unwinding mechanism 210 ; optionally, the traction mechanism 260 is arranged downstream of the tension control mechanism 250 .

[0161] Please refer to FIG11 , which is a schematic structural diagram of the traction mechanism of the glue-applying mechanism shown in FIG1 a .

[0162] The traction mechanism 260 includes a traction motor 261 , a traction coupling 262 , a rotating roller 263 , a roller positioning block 264 , a positioning roller 265 , a roller cylinder 266 , and a traction positioning plate 267 .

[0163] The rotating roller 263 is connected to the traction motor 261 via the traction coupling 262. The traction positioning plate 267 is fixed to the housing of the traction motor 261. Two roller positioning blocks 264 are spaced apart on the traction positioning plate 267. The roller positioning blocks 264 are provided with mounting holes (not shown); one end of the rotating roller 263 passes through the mounting hole of one roller positioning block 264 and is connected to the traction coupling 262, and the other end of the rotating roller 263 is located in the mounting hole of the other roller positioning block 264. The positioning roller 265 is arranged corresponding to the rotating roller 263, and the roller cylinder 266 is configured to drive the positioning roller 265 to move toward or away from the rotating roller 263. The roller cylinder 266 is connected to the control component, which is further configured to control the roller cylinder 266 to drive the positioning roller 265 to move toward or away from the rotating roller 263. The traction motor 261 is connected to the control component, and the control component is also configured to control the operation of the traction motor 261.

[0164] The roller cylinder 266 drives the positioning roller 265 to move toward the rotating roller 263, and the tape 701 is pre-pressed between the positioning roller 265 and the rotating roller 263; the traction motor 261 transmits to the rotating roller 263, driving the rotating roller 263 to rotate, thereby controlling the conveying speed of the entire tape 701.

[0165] In one embodiment, the traction motor 261 is electrically connected to the unwinding oscillating roller assembly 230. The unwinding oscillating roller assembly 230 is configured to detect the tension of the adhesive tape 701 released by the unwinding assembly 211 and provide feedback to the control assembly. The control assembly is configured to receive the tension feedback from the unwinding oscillating roller assembly 230 and adjust the driving force of the traction motor 261 based on the tension feedback from the unwinding oscillating roller assembly 230, thereby adjusting the transmission speed of the adhesive tape 701. Specifically, the traction motor 261 controls the rotational speed of the rotating roller 263, thereby controlling the transmission speed of the adhesive tape 701.

[0166] It should be noted that the control component is configured to simultaneously control the unwinding motor 2111 and the traction motor 261 based on the tension signal of the tape 701 detected by the unwinding roller assembly 230, so that the speed at which the unwinding reel 2121 releases the tape 701 matches the transmission speed of the tape 701 downstream of the unwinding mechanism 210, thereby keeping the tape 701 in a good gluing state and achieving a good gluing effect.

[0167] Continuing with Figure 1a, the gluing mechanism 200 further includes a plurality of deflection correction guide wheel assemblies 215 and a plurality of positioning guide wheel assemblies 216. Both the deflection correction guide wheel assemblies 215 and the positioning guide wheel assemblies 216 are located downstream of the unloading mechanism 210; alternatively, the plurality of deflection correction guide wheel assemblies 215 and the plurality of positioning guide wheel assemblies 216 are located downstream of the second deflection correction detection assembly 240 and upstream of the tension control mechanism 250.

[0168] Several deflection-correcting guide wheel assemblies 215 and several positioning guide wheel assemblies 216 are arranged sequentially along the transport path of the adhesive tape 701; that is, the adhesive tape 701 passes through the several deflection-correcting guide wheel assemblies 215 before passing through the several positioning guide wheel assemblies 216. The deflection-correcting guide wheel assemblies 215 and the positioning guide wheel assemblies 216 work together to correct any deviations in the transport of the adhesive tape 701. The deflection-correcting guide wheel assemblies 215 and the positioning guide wheel assemblies 216 are structural components that guide the transport of the adhesive tape 701.

[0169] The specific structure of the several correcting guide wheel assemblies 215 and the several positioning guide wheel assemblies 216 and the specific setting method for realizing the correction of the tape 701 can be referred to the relevant introduction of the correcting guide wheel assembly 215 and the positioning guide wheel assembly 216 in the discharge mechanism 210, and will not be repeated here.

[0170] Continuing with FIG1a, the gluing device 1000 further includes a feed bias detection mechanism 300 and a gluing correction mechanism 400. The feed bias detection mechanism 300 is disposed at the feed end A of the support mechanism 100. The feed bias detection mechanism 300 is configured to detect the positional offset of the electrode piece. The gluing correction mechanism 400 is connected to the support mechanism 100. The gluing correction mechanism 400 is configured to drive the support mechanism 100 to move along a transmission direction perpendicular to the electrode piece based on the positional offset of the electrode piece detected by the feed bias detection mechanism 300. The feeding bias detection mechanism 300 and the gluing correction mechanism 400 are respectively connected to the control component, which is configured to receive the position offset of the electrode detected by the feeding bias detection mechanism 300, and control the gluing correction mechanism 400 to drive the support mechanism 100 to move along the transmission direction perpendicular to the electrode according to the position offset of the electrode fed back by the feeding bias detection mechanism 300, thereby driving the gluing mechanism 200 arranged on the support mechanism 100 to move, so as to maintain the tape 701 released by the gluing mechanism 200 aligned with the part of the electrode to be glued, thereby maintaining the gluing accuracy and having a better gluing effect.

[0171] Please refer to FIG. 12 , which is a schematic structural diagram of the feed bias detection mechanism of the gluing device shown in FIG. 1 a .

[0172] The feed offset detection mechanism 300 is a structural component that detects the positional offset of the electrode when it enters the gluing mechanism 200 for gluing. The feed offset detection mechanism 300 includes a electrode feed correction motor 301, a third motor coupling 302, a electrode positioning guide shaft 303, a third screw 304, a electrode bearing seat 305, a electrode detection plate 306, a electrode detection sensor 307, a electrode detection seat 308, and a third sensor 309.

[0173] The electrode detection plate 306 refers to a structural component that forms the electrode detection area. The electrode detection plate 306 is provided with an opening 3061, which forms the detection area of ​​the electrode. The electrode passes through the opening 3061. Specifically, the electrode detection plate 306 is connected to the electrode bearing seat 305; a portion of the electrode detection plate 306 extends outside the electrode bearing seat 305, that is, the orthographic projection of the portion of the electrode detection plate 306 on the electrode bearing seat 305 is not covered by the electrode bearing seat 305; and the portion of the electrode detection plate 306 that extends outside the electrode bearing seat 305 is provided with an opening 3061.

[0174] The pole piece bearing seat 305 is mounted on the third screw rod 304 and can move back and forth with the rotation of the linearly extending third screw rod 304. The pole piece bearing seat 305 is a structural component that fixes the pole piece detection plate 306 and can drive the pole piece detection plate 306 to move back and forth along the straight line.

[0175] The third screw rod 304 is connected to the electrode feeding and correcting motor 301 through the third motor coupling 302. When the electrode enters the vicinity of the opening 3061 (i.e., the electrode detection area), the third screw rod 304 is driven to rotate by the electrode feeding and correcting motor 301, thereby driving the electrode detection plate 306 to move back and forth along a straight line to confirm the detection position of the electrode. The detection position of the electrode is the position where the electrode is to be glued.

[0200] The hot pressing roller mechanism 600 includes a hot pressing roller 602 and a heating component 603. The heating component 603 is spaced apart from the hot pressing roller 602, and the heating component 603 is configured to perform non-contact heating on the hot pressing roller 602. For contact heating, the heating component needs to rotate together with the hot pressing roller, and an annular electrode needs to be introduced to maintain power supply to the heating component; the embodiment of the present application adopts non-contact heating, eliminating the annular electrode and reducing the complexity of the equipment structure. In addition, by adopting non-contact heating, no structural parts are introduced on the surface of the hot pressing roller 602, which can improve the phenomenon of foreign matter being introduced on the surface of the electrode during the hot pressing of the electrode by the hot pressing roller 602, thereby improving the glue bonding yield. The hot pressing roller mechanism 600 is used to hot press the electrode after gluing, and the tape 701 on the surface of the electrode is smoothed and compacted, thereby strengthening the tightness of the fit between the tape 701 and the electrode, and improving the glue bonding yield.

[0201] In one embodiment, the heating temperature of the heating component 603 is adjustable within the range of 20° C. to 180° C. The heating temperature can be selected according to needs to improve the adhesive bonding yield.

Optionally, a heating component 603 is provided at each of the opposite ends of the hot pressing roller 602 to achieve efficient heating of the hot pressing roller 602 and maintain temperature consistency at all locations of the hot pressing roller 602.

[0204] In one embodiment, the hot press roller mechanism 600 further includes a hot press base 605. The hot press roller 602 and the heating assembly 603 are respectively connected to the hot press base 605. The orthographic projection of the hot press roller 602 on the hot press base 605 at least partially overlaps with the orthographic projection of the heating assembly 603 on the hot press base 605. The hot press base 605 is made of a transparent material, and the heating assembly 603 is a heat radiating assembly. Heat from the heating assembly 603 is transferred to the hot press roller 602 through the transparent hot press base 605, achieving non-contact heating. By ensuring that the orthographic projections of the hot press roller 602 and the heating assembly 603 on the hot press base 605 at least partially overlap, the heat conduction path is shortened and heat utilization efficiency is improved. Optionally, a heating assembly 603 is provided at opposite ends of the hot press roller 602 to achieve efficient heating of the hot press roller 602 and maintain temperature consistency across the hot press roller 602.

[0205] In one embodiment, when the heating component 603 is a hot air blowing component, the air outlet direction of the hot air blowing component is perpendicular to the axial direction of the hot pressing roller 602, thereby achieving non-contact heating. The angle between the air outlet direction of the hot air blowing component and the transmission direction of the electrode is 30 degrees to 60 degrees. The angle between the air outlet direction of the heating component 603 and the transmission direction of the electrode is 30 degrees to 60 degrees, thereby reducing the interference of the hot pressing roller 602 in squeezing the electrode, while achieving efficient heating of the hot pressing roller 602 and achieving a better hot pressing effect. Optionally, along the axial direction of the hot pressing roller 602, the width of the air outlet of the heating component 603 is greater than or equal to the length of the hot pressing roller 602, so that the heat is evenly distributed in all parts of the hot pressing roller 602, and the temperature consistency of all parts of the hot pressing roller 602 is maintained.

[0206] In one embodiment, the hot-press roller mechanism 600 further includes a temperature sensor 604 configured to detect the temperature of the hot-press roller 602.

Specifically, the hot pressing driver 601 is connected to a control component, which is configured to control the hot pressing driver 601 to drive the hot pressing roller 602 to move toward or away from the pole piece. In other words, the control component is configured to control the distance between the hot pressing roller 602 and the pole piece of the hot pressing roller mechanism 600. The distance between the hot pressing roller and the pole piece is automatically adjusted by the control component and the hot pressing driver 601. Optionally, the hot pressing driver 601 may be a cylinder.

[0208] In one embodiment, the hot pressing roller mechanism 600 includes two hot pressing rollers 602, which are respectively arranged on opposite sides of the transmission path of the electrode. There is a hot pressing roller 602 on the opposite sides of the electrode to heat-press the tape 701 on the surface of the electrode, so that the tape 701 attached to the surface of the electrode is more conformable to the electrode.

[0209] Each hot pressing roller 602 is respectively provided with a heating component 603, a hot pressing drive 601 and a temperature sensor 604. When a tape 701 is attached to one surface of the electrode, the two hot pressing rollers 602 squeeze the two opposite surfaces of the electrode to achieve a tight fit between the tape 701 and the electrode, and the support plate provided on the surface of the electrode without the tape can be omitted (if there is only one hot pressing roller 602, a support plate is provided on the other side of the electrode, and the support plate supports the electrode so that the hot pressing roller 602 can squeeze the electrode). When the two opposite surfaces of the electrode are respectively attached with tape 701, the two hot pressing rollers 602 squeeze the two opposite surfaces of the electrode to achieve a tight fit between the tape 701 attached to the two surfaces of the electrode and the electrode. The two hot pressing drives 601 are controlled by the control component to adjust the distance between the two hot pressing rollers 602, and then adjust the squeezing force on the surface of the electrode. Optionally, two hot pressing rollers 602 are axially symmetrically arranged to squeeze the pole piece from both sides to keep the tape at each location of the pole piece in close contact with the pole piece.

[0210] When the electrode is initially extruded by the cold pressing roller mechanism 500, the hot pressing roller 602 is heated to the set temperature at the same time; after the electrode is initially extruded by the cold pressing roller mechanism 500, it enters the extrusion range of the hot pressing roller mechanism 600, and the hot pressing drive component 601 drives the hot pressing roller 602 to approach the electrode and extrude the electrode again.

[0211] Continuing with Figure 14, the preheating assembly 900 includes a hot air blowing assembly, and the hot air outlet assembly includes a hot air blowing gun 901 and a hot air blowing gun cover 902. The hot air blowing gun cover 902 is located at the end of the hot air blowing gun 901 near the electrode. The hot air blowing gun cover 902 collects the hot air blown by the hot air blowing gun 901, allowing the hot air to act on the electrode as much as possible, thereby improving heat utilization. Optionally, the hot air blowing gun cover 902 is trumpet-shaped. Optionally, the air outlet direction of the hot air blowing gun cover 902 is at an angle of 80-100 degrees to the electrode transmission direction, thereby improving the heat utilization rate of the hot air blown by the hot air blowing gun 901 and achieving a better preheating effect on the tape on the electrode.

[0220] The medium 6022 can be a liquid, such as water, oil, etc. By disposing the liquid medium 6022 within the housing 6021, the cooling rate of the hot press roller 602 is slowed down, thereby improving the energy utilization of the heating component 603 and maintaining a constant temperature of the hot press roller 602. In this case, the heating component 603 can be a hot air blowing component or a heat radiation component.

[0221] When the heating component 603 is a heat radiation component, the medium 6022 can be a material that can absorb electromagnetic waves and release heat, such as carbon black, graphite, etc. By designing the material of the medium 6022 as described above, the medium 6022 can quickly heat up and cool down along with the heating component 603, which is conducive to accurately controlling the temperature of the hot pressing roller 602.

The heating component 603 is a heat radiation component, and the heat of the heating component 603 is radiated to the first surface, which is diffusely reflected so that this part of the heat heats the medium 6022 in the receiving cavity, thereby improving the energy utilization rate of the heating component 603 and improving the temperature uniformity of the medium 6022 at various locations, thereby improving the temperature uniformity of the hot pressing roller 602 at various locations.
