[0008] In order to solve the above technical problems, the present disclosure provides a glue applying system and a glue applying method to improve the glue applying efficiency.

[0009] The present disclosure is achieved through the following technical solutions.

[0010] A first aspect of the present disclosure provides a gluing system, wherein a film roll includes a first release paper, a second release paper, and a glue located between the first and second release papers. The gluing system includes a support device, a first drive mechanism, and a gluing device. The support device is used to support the object to be glued. The gluing device includes:

The sizing roller, the first receiving roller, and the second receiving roller are all rotatably connected to the mounting base. The sizing roller is used to drive the film to rotate to release the film. The first receiving roller is used to wind the first release paper during rotation to separate the first release paper from the second release paper. The second receiving roller is used to wind the second release paper during rotation.

[0014] A second driving mechanism is installed on the mounting base, the first and second take-up rollers are both drivingly connected to the second driving mechanism, and the second driving mechanism is used to drive at least the first and second take-up rollers to rotate;

[0015] The glue applying device further comprises a first colloid detector, which is connected to the mounting base and is used for detecting the colloid before it moves from the glue roller to the pressure roller.

[0016] In the disclosed embodiment, a second drive mechanism drives the first and second take-up rollers to rotate, separating the first and second release liners and transferring the adhesive on the second release liners to the pressure roller. This improves the efficiency of separating the first release liners and, consequently, the efficiency of adhesive application. The first colloid detector detects the adhesive, minimizing the risk of adhesive leakage from the pressure roller.

[0017] In one embodiment, the pressing roller has a conveying surface for contacting the second release paper, and the conveying surface at least partially protrudes from the outside of the mounting base.

[0018] In the disclosed embodiment, the protruding conveying surface is beneficial for glue pressing.

[0019] In one embodiment, the direction in which the conveying surface protrudes from the mounting base is the first direction, and the material roller assembly is located on the side of the pressure roller away from the first direction.

[0020] In the disclosed embodiment, the material roller assembly is relatively far away from the adhesive-coated object, so as to prevent the adhesive on the material roller assembly from accidentally sticking to the adhesive-coated object.

[0021] In one embodiment, the material roller assembly further comprises:

[0022] a first redirecting roller, rotatably connected to the mounting base, and configured to convey the second release paper during rotation;

[0023] The second redirecting roller is rotatably connected to the mounting base, and is used to convey the second release paper during rotation. The center line of the first redirecting roller and the second redirecting roller is the first line, and the common tangent line of the outer contour of the first redirecting roller and the outer contour of the second redirecting roller is the second line. The second line is located on one side of the first line. The first colloid detector has a detection part for detection, and a straight line that coincides with the detection part and is parallel to the detection direction of the detection part intersects with the second line.

[0024] In the embodiment of the present disclosure, the first bend roller and the second bend roller are adapted to the detection direction of the detection portion of the first colloid detector, so that the position of the first colloid detector can be flexibly arranged.

[0025] In one embodiment, the center line connecting the second redirecting roller and the pressure roller is the third line, the angle between the first line and the third line is the first preset angle, the first preset angle is less than 180°, and the rubber roller is located on the side of the second redirecting roller facing the first preset angle.

[0026] In the embodiment of the present disclosure, the rubber roller is arranged by utilizing the space on the side of the second redirecting roller facing the first preset angle, thereby improving space utilization.

[0027] In one embodiment, the material roller assembly further comprises:

[0028] A carrying roller, rotatably connected to the mounting base;

[0029] The top roller is rotatably connected to the mounting base, and the top roller is arranged opposite to the carrying roller to clamp the second release paper between the carrying roller and the top roller.

[0030] In the embodiment of the present disclosure, the second release paper between the carrying roller and the second take-up roller is made tight, so that the release paper wound on the second take-up roller can be well aligned.

[0031] In one embodiment, the center line of the pressure roller and the supporting roller is the fourth line, the center line of the supporting roller and the second receiving roller is the fifth line, the angle between the fourth line and the fifth line is the second preset angle, and the second preset angle is less than 180°. The material roller assembly also includes a transition roller rotatably connected to the mounting base, and the transition roller is located on the side of the supporting roller facing the second preset angle.

[0032] In the disclosed embodiment, the belt transmission wrap angle of the pressure roller and the belt transmission wrap angle of the carrier roller are increased by the transition roller to prevent the second release paper from slipping during the conveying process.

[0033] In one embodiment, the glue-applying device further includes a second colloid detector connected to the glue-applying side of the mounting base, and a detection direction of the second colloid detector is toward the glue-applying side of the mounting base.

[0034] In the embodiment of the present disclosure, the second colloid detector is used to detect the glued object after gluing to identify whether the corresponding positions of the glued object are all glued.

[0035] In one embodiment, the rubber roller is drivingly connected to the second driving mechanism, and the second driving mechanism is also used to drive the rubber roller to rotate.

[0036] In the embodiment of the present disclosure, the second driving mechanism drives the glue roller, the first receiving roller and the second receiving roller to rotate, so that the second release paper and the first release paper can be better tensioned during the conveying process, which is conducive to better conveying the first release paper and the second release paper.

[0037] In one embodiment, the object to be glued is an unused rolled current collector; and / or, there are multiple colloids, and the multiple colloids are arranged at intervals between the first release paper and the second release paper.

[0038] A second aspect of the present disclosure provides a method for applying glue, including:

[0039] When the mounting base is in a pre-pressing position relative to the supporting device and has not yet been glued, the second driving mechanism drives at least the first and second take-up rollers to rotate, so that the second release paper with the first release paper removed drives the glue to move to the pressing roller;

[0040] The first driving mechanism drives one of the supporting device and the mounting base located at the pre-pressing position closer to the other, so that the pressing roller presses the adhesive on the second release paper toward the adhesive-coated object;

[0041] driving one of the supporting device and the mounting base away from the other by a first driving mechanism, so that the adhesive adhered to the adhesive object is separated from the second release paper;

[0042] The first colloid detector is connected to the mounting base, and is used for detecting the colloid before it moves from the rubber roller to the pressure roller.

[0043] In the embodiment of the present disclosure, at least the first and second receiving rollers are driven to rotate by the second driving mechanism to separate the first release paper from the second release paper, and the glue of the second release paper is transported to the pressure roller. The mounting base is driven to move by the first driving mechanism so that the glue at the pressure roller can be pressed toward the glued object, thereby realizing the automation of the entire glue laminating process and improving the glue laminating efficiency.

[0044] In one embodiment, the number of pre-pressing positions corresponding to the adhesive laminating object is multiple, and the multiple pre-pressing positions are arranged in sequence. The adhesive laminating method further includes:

[0045] When the glue on the glued object is separated from the second release paper, the first driving mechanism drives one of the support device and the mounting base to move relative to the other, so that the mounting base is located at another pre-pressing position adjacent to the reference pre-pressing position relative to the support device, and the reference pre-pressing position is the pre-pressing position corresponding to the glue separated from the second release paper.

[0046] In the embodiment of the present disclosure, the first driving mechanism drives the mounting base to move from the debonding position to another pre-pressing position, thereby achieving sequential gluing at multiple different positions on the gluing object.

[0047] In one embodiment, one of the pre-pressing positions is a target position, and among all the pre-pressing positions, except the target position, the remaining pre-pressing positions are located on one side of the target position. The adhesive application method further includes:

[0048] The first driving mechanism drives one of the mounting base and the supporting device to move relative to the other, so that the mounting base is located at a target position relative to the supporting device.

[0049] In the embodiment of the present disclosure, the mounting base can complete the gluing at all pre-pressing positions by moving in one direction starting from the target position, which is beneficial to shortening the moving path of the mounting base during the gluing process.

[0050] In one embodiment, when the mounting base is in a pre-pressing position relative to the supporting device and has not yet been glued, the second driving mechanism drives at least the first and second take-up rollers to rotate, so that the second release paper removed from the first release paper drives the glue to move to the pressure roller, including:

[0051] In the process of the second driving mechanism driving at least the first and second receiving rollers to rotate, when the first colloid detector detects the colloid on the second release paper, the second driving mechanism drives at least the first and second receiving rollers to rotate, driving the second release paper to move a preset distance, so that the corresponding colloid moves to the pressure roller.

[0052] In the embodiment of the present disclosure, when the first colloid detector detects that the colloid is triggered, the second release paper moves a preset distance, which can drive the corresponding colloid to move a preset distance, thereby allowing the colloid to move to the pressure roller more accurately.

[0053] Effects of the invention:

[0054] The disclosed embodiment drives the first and second take-up rollers to rotate through the second drive mechanism, driving the glue roller and the film to rotate so as to release the film and tear off the first release paper. The second release paper removed from the first release paper moves toward the pressure roller so that the glue on the second release paper can move to the pressure roller. The pressure roller presses the corresponding glue on the second release paper toward the glue-applying object, thereby automating the process of tearing off the first release paper and conveying the glue removed from the first release paper to the pressure roller, thereby improving the efficiency of tearing off the first release paper and correspondingly improving the glue-applying efficiency.

[0064] The following embodiments of the technical solution of the present disclosure are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present disclosure and are therefore only examples and are not intended to limit the scope of protection of the present disclosure.

[0065] 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 disclosure belongs; the terms used herein are for the purpose of describing specific embodiments only and are not intended to limit this disclosure; the terms "including" and "having" of the embodiments of this disclosure and any variations thereof are intended to cover non-exclusive inclusions.

[0066] In the description of the embodiments of the present disclosure, technical terms such as "first," "second," and "third" are used solely to distinguish different objects and should not be understood to indicate or imply relative importance or to implicitly specify the quantity, specific order, or primary and secondary relationship of the technical features indicated. In the description of the embodiments of the present disclosure, "plurality" means more than two, unless otherwise specifically defined.

[0067] 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 disclosure. 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.

[0068] In the description of the embodiments of the present disclosure, 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 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.

[0069] In the description of the embodiments of the present disclosure, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal connectivity between two components or interaction between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present disclosure based on specific circumstances.

[0070] In the description of the embodiments of the present disclosure, unless otherwise clearly specified and limited, the technical term "contact" should be understood in a broad sense, and can be direct contact or contact through an intermediate medium layer. It can be contact with essentially no interaction force between the two contacting parties, or it can be contact with interaction force between the two contacting parties.

[0071] As part of the creative concept of the present disclosure, before describing the embodiments of the present disclosure, it is necessary to analyze the reasons for the low glue application efficiency in related technologies, and obtain the technical solutions of the embodiments of the present disclosure through reasonable analysis.

[0072] In the related art, during the roll-changing process, the glue application of the rolled current collector requires tearing off the first release paper of the film, and then pasting the colloid on the rolled current collector. The process of tearing off the first release paper is mainly completed manually. The efficiency of manually tearing off the first release paper is affected by individual factors. Some people tear off the first release paper faster, while others tear off the first release paper slower. Moreover, after the operator works for a long time, the efficiency of tearing off the first release paper of the film will decrease. The reduced efficiency of tearing off the first release paper correspondingly reduces the efficiency of the overall glue application.

[0073] The embodiment of the present disclosure drives at least the first and second take-up rollers to rotate through the second drive mechanism to separate the first release paper from the second release paper and the colloid, thereby automatically peeling off the first release paper and transporting the colloid to the pressing roller for lamination.

[0074] Bare cells are an important component of battery cells.

[0075] There can be multiple battery cells, and these cells can be connected in series, in parallel, or in a hybrid configuration. A hybrid configuration refers to a combination of both series and parallel connections. Multiple battery cells can be directly connected in series, in parallel, or in a hybrid configuration to form a battery pack. Of course, multiple battery cells can first be connected in series, in parallel, or in a hybrid configuration to form a battery module, which can then be connected in series, in parallel, or in a hybrid configuration to form a battery pack. A battery pack may also include other structures, such as a busbar assembly for electrically connecting multiple battery cells.

[0076] A battery cell is a unit that can convert chemical energy into electrical energy.

[0077] In the embodiment of the present disclosure, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0078] In the embodiments of the present disclosure, the battery cells may be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-hydrogen batteries, nickel-cadmium batteries, lead-acid batteries, etc., but the embodiments of the present disclosure are not limited to this.

[0079] Bare cells can be made by winding or stacking electrodes.

[0080] The pole piece includes a current collector and an active material disposed on at least one side surface of the current collector.

[0081] The current collector has an overall sheet-like structure and can be rolled up.

[0082] The current collector can be a metal foil or a composite current collector.

[0083] For example, the metal foil may be made of stainless steel, copper, aluminum, nickel or titanium.

[0084] For example, the composite material is a combination of a metal material and a polymer matrix.

[0085] The embodiment of the present disclosure provides a glue laminating system, as shown in FIG4 , which includes a supporting device 400 , a first driving mechanism 300 , and a glue laminating device 200 . The supporting device 400 is used to support a glue laminating object 500 .

[0086] Exemplarily, the first driving mechanism 300 may be a motor or a combination of a motor and a transmission component.

[0087] Referring to Figure 1 , a film roll 100 according to the present embodiment includes a first release liner 101, a second release liner 103, and an adhesive 102 positioned between the first and second release liner 101, 103. During the adhesive laminating process, the first release liner 101 is separated from the adhesive 102 to expose the adhesive 102. The adhesive 102 adheres to the second release liner 103. After the first release liner 101 is removed, the adhesive 102 is affixed to the adhesive object 500.

[0088] It should be noted that both the side of the colloid 102 facing the first release paper 101 and the side of the colloid 102 facing the second release paper 103 are sticky, that is, the colloid 102 is a double-sided adhesive tape.

[0089] The first release paper 101 and the second release paper 103 are mainly used to isolate the sticky surface of the colloid 102 to maintain the stickiness of the surface of the colloid 102 as much as possible.

[0090] For example, the adhesive-coated object 500 may be a rolled current collector.

[0091] It is understood that the adhesive-coated object 500 is not limited to a rolled current collector. For example, the adhesive-coated object 500 can be other objects that need to be adhesive-coated except the current collector.

[0092] For example, referring to FIG1 , there are multiple colloids 102 between the first release paper 101 and the second release paper 103 . The multiple colloids 102 are arranged in sequence and spaced apart.

[0093] Exemplarily, the colloid may be double-sided yellow tape.

[0094] In one embodiment, referring to Figures 1 to 4 , the gluing device 200 includes a mounting base 1, a material roller assembly 2, a pressure roller 3, and a second drive mechanism 4. The support device 400 and / or the mounting base 1 are drivably connected to a first drive mechanism 300. The first drive mechanism 300 is configured to provide power to move one of the support device 400 and the mounting base 1 relative to the other. The material roller assembly 2 includes a sizing roller 21, a first take-up roller 22, and a second take-up roller 23. The sizing roller 21, the first take-up roller 22, and the second take-up roller 23 are all rotatably connected to the mounting base 1. The sizing roller 21 is configured to rotate the film roll 100 to release the film roll 100. The first take-up roller 22 is configured to wind the first release paper 101 during rotation to separate the first release paper 101 from the second release paper 103. The second take-up roller 23 is configured to wind the second release paper 103 during rotation. The pressure roller 3 is rotatably connected to the mounting base 1. The pressure roller 3 is used to convey the second release paper 103 during rotation and to press the adhesive 102 on the second release paper 103 toward the adhesive-coated object 500. A second drive mechanism 4 is mounted on the mounting base 1. Both the first and second take-up rollers 22, 23 are rotatably connected to the second drive mechanism 4. The second drive mechanism 4 is used to rotate at least the first and second take-up rollers 22, 23.

[0095] The mounting base 1 is mainly used to support other structures of the gluing device 200 , and the mounting base 1 serves as a mounting foundation for other components of the gluing device 200 .

[0096] For example, referring to FIG. 1 and FIG. 2 , the mounting base 1 may be in a plate shape or a box shape.

[0097] Exemplarily, the film 100 is sleeved on the rubber roller 21 , and the film 100 is gradually released as the rubber roller 21 rotates.

[0098] For example, referring to FIG. 1 and FIG. 2 , the adhesive roller 21 drives the film 100 to rotate in a counterclockwise direction as indicated by an arrow R1 to gradually release the film 100 .

[0099] Exemplarily, a first tray is formed at one end of the rubber roller 21 facing the mounting base 1 , and the first tray is used to carry the film 100 sleeved on the rubber roller 21 .

[0100] For example, the first release paper 101 of the film 100 is wound on the first receiving roller 22. As the first receiving roller 22 rotates, the first release paper 101 separated from the second release paper 103 is continuously wound onto the first receiving roller 22, and the first release paper 101 separated from the second release paper 103 is collected by the first receiving roller 22.

[0101] Exemplarily, referring to FIG. 1 and FIG. 2 , the first receiving roller 22 rotates in a clockwise direction indicated by an arrow R2 so that the first release paper 101 is wound around the first receiving roller 22 .

[0102] Exemplarily, a second tray is formed at one end of the first receiving roller 22 facing the mounting base 1 , and the second tray is used to carry the first release paper 101 wound on the first receiving roller 22 .

[0103] Illustratively, the second release paper 103 of the film 100 is wound on the second receiving roller 23 . As the second receiving roller 23 rotates, the second release paper 103 is continuously wound on the second receiving roller 23 , and the second release paper 103 is collected by the second receiving roller 23 .

[0104] Exemplarily, referring to FIG. 1 and FIG. 2 , the second receiving roller 23 rotates in a clockwise direction indicated by an arrow R3 so that the second release paper 103 is wound around the second receiving roller 23 .

[0105] Exemplarily, a third tray is formed at one end of the second receiving roller 23 facing the mounting base 1 , and the third tray is used to carry the second release paper wound on the second receiving roller 23 .

[0106] The second drive mechanism 4 drives the first take-up roller 22 to rotate, which can drive the sizing roller 21 and the film 100 mounted thereon to rotate via the first release paper 101, thereby releasing the film 100. The second drive mechanism 4 drives the second take-up roller 23 to rotate, which can drive the sizing roller 21 and the film 100 mounted thereon to rotate via the second release paper 103. The second drive mechanism 4 drives the second take-up roller 23 to rotate, providing power for the movement of the second release paper 103.

[0107] Illustratively, the linear speed at which the first release paper 101 is moved by the rotation of the first receiving roller 22 is a first speed, and the linear speed at which the second release paper 103 is moved by the rotation of the second receiving roller 23 is a second speed. The first speed and the second speed are approximately equal, so that the first release paper 101 and the second release paper 103 can both be kept in a tensioned state as much as possible, and the first release paper 101 and the second release paper 103 can be separated relatively smoothly.

[0108] Exemplarily, the second driving mechanism 4 may include a plurality of motors, and the first taking-up roller 22 and the second taking-up roller 23 are each driven by one motor.

[0109] Illustratively, the second driving mechanism 4 may include a motor and a transmission component. The motor drives the transmission component to move, and the transmission component drives the first and second receiving rollers 22 and 23 to rotate respectively.

[0110] 1 , the second release paper 103 released from the film 100 moves toward the second receiving roller 23 via the pressure roller 3 , and the pressure roller 3 abuts against the side of the second release paper 103 facing away from the colloid 102 . The moving second release paper 103 drives the pressure roller 3 to rotate.

[0111] For example, referring to FIG. 1 , the second release paper 103 released from the film roll 100 is sequentially wound around the pressing roller 3 and the second receiving roller 23 .

[0112] Exemplarily, the first driving mechanism 300 drives the mounting base 1 to move, so that the pressing roller 3 on the mounting base 1 presses the adhesive 102 toward the adhesive-coated object 500 .

[0113] Illustratively, the first driving mechanism 300 drives the supporting device 400 to move, so that the glued object 500 on the supporting device 400 moves toward the glue 102 on the pressing roller 3 , thereby pressing the glue 102 on the pressing roller 3 toward the glued object 500 .

[0114] Exemplarily, the second driving motor drives the mounting base 1 and the supporting device 400 to move, so that the mounting base 1 and the supporting device 400 approach each other, thereby pressing the adhesive 102 at the pressing roller 3 toward the adhesive-coated object 500 .

[0115] In the embodiment of the present disclosure, the first take-up roller 22 and the second take-up roller 23 are driven to rotate by the second driving mechanism 4, which drives the glue roller 21 and the film 100 to rotate so that the film 100 is released and the first release paper 101 is torn off. The second release paper 103 removed from the first release paper 101 moves toward the pressure roller 3 so that the glue 102 on the second release paper 103 can move to the pressure roller 3. The corresponding glue 102 on the second release paper 103 is pressed toward the glue-applying object 500 by the pressure roller 3, thereby realizing the automation of the process of tearing off the first release paper 101 and conveying the glue 102 removed from the first release paper 101 to the pressure roller 3, thereby improving the efficiency of tearing off the first release paper 101, thereby correspondingly improving the efficiency of glue-applying. The first release paper 101 is separated from the glue 102 by the glue laminating device 200, and the glue 102 is transported to the pressure roller 3. The second drive motor drives the mounting base 1 and / or the support device 400 to move so as to press the glue 102 on the pressure roller 3 toward the glue laminating object 500, thereby automating the entire glue laminating process, reducing the degree of manual intervention, and improving the efficiency of glue laminating.

[0116] It is understood that the gluing process does not necessarily require the first drive mechanism 300 to be driven. For example, the gluing device 200 separates the first release paper 101 from the adhesive 102 and transports the adhesive 102 to the pressing roller 3. After the adhesive 102 is transported, the operator adheres the adhesive 102 at the pressing roller 3 to the adhesive object 500.

[0117] In one embodiment, referring to FIG. 1 and FIG. 2 , the pressing roller 3 has a conveying surface 31 for contacting the second release paper 103 , and the conveying surface 31 at least partially protrudes from the outside of the mounting base 1 .

[0118] For example, referring to FIG. 1 , the pressing roller 3 abuts against the side of the second release paper 103 facing away from the colloid 102 , and the conveying surface 31 contacts the side of the second release paper 103 facing away from the colloid 102 .

[0119] In the embodiment of the present disclosure, since the conveying surface 31 at least partially protrudes from the outside of the mounting base 1, the side of the second release paper 103 facing away from the conveying surface 31 is conducive to making the colloid 102 protrude from the mounting base 1. During the process of contact between the colloid 102 and the rolled current collector, the possibility of interference between the current collector and the mounting base 1 can be reduced, so that the pressing roller 3 can better press the colloid 102 onto the current collector.

[0120] In one embodiment, referring to FIG. 1 and FIG. 2 , the direction in which the conveying surface 31 protrudes from the mounting base 1 is a first direction, and the material roller assembly 2 is located on a side of the pressure roller 3 that is away from the first direction.

[0121] Please refer to FIG. 2 , the first direction is the direction indicated by arrow R4 in the figure.

[0122] For example, referring to FIG. 1 and FIG. 2 , the sizing roller 21 , the first receiving roller 22 , and the second receiving roller 23 are all located on the side of the pressure roller 3 facing away from the first direction.

[0123] In the embodiment of the present disclosure, since the material roller assembly 2 is located on the side of the pressure roller 3 away from the first direction, the second release paper 103 at the position of the material roller assembly 2 is correspondingly located on the side of the pressure roller 3 away from the first direction, and the second release paper 103 at the position of the pressure roller 3 is more protruding relative to the second release paper 103 at the position of the material roller assembly 2. When the pressure roller 3 presses the colloid 102 onto the rolled current collector, the second release paper 103 at the position of the material roller assembly 2 is far away from the rolled current collector, which can reduce the possibility of the colloid 102 on the second release paper 103 at the material roller assembly 2 accidentally sticking to the rolled current collector.

[0124] It is understood that the arrangement of the material roller assembly 2 is not limited. For example, the material roller assembly 2 can be partially flush with the pressure roller 3, or the material roller assembly 2 can be partially located on the side of the pressure roller 3 facing the first direction.

[0125] It is understandable that the arrangement of the conveying surface 31 is not limited. For example, the conveying surface 31 can be located within the range of the mounting base 1, and the conveying surface 31 does not protrude from the mounting base 1.

[0126] In one embodiment, referring to FIG. 1 and FIG. 2 , the glue applying device 200 further includes a first colloid detector 5 , which is connected to the mounting base 1 and is used to detect the colloid 102 before it moves from the glue roller 21 to the pressure roller 3 .

[0127] For example, the first colloid detector 5 may be a color sensor, which identifies the color of the colloid 102 through the color sensor, thereby determining whether the colloid 102 passes through the first colloid detector 5 .

[0128] For example, the color of the colloid 102 may be yellow.

[0129] Exemplarily, referring to FIG. 1 and FIG. 2 , the first colloid detector 5 is located on a side of the pressing roller 3 that is away from the first direction.

[0130] In the embodiment of the present disclosure, the first colloid detector 5 can detect the colloid 102 that moves before the pressure roller 3. When the colloid 102 passes through the first colloid detector 5, the second release paper 103 drives the colloid 102 to move a preset distance to reach the pressure roller 3, and then presses the colloid 102 at the pressure roller 3 toward the glue-applying object 500. When the first colloid detector 5 does not detect the colloid 102, the pressure roller 3 will not perform the corresponding glue pressing action, which can reduce the possibility of glue missing on the glue-applying object 500.

[0131] It is understandable that the first colloid detector 5 is not limited to the position where the colloid 102 is detected. The first colloid detector 5 can detect the colloid 102 at the corresponding position according to actual needs.

[0132] It is understandable that the glue applying device 200 may not be provided with the first colloid detector 5 .

[0133] In one embodiment, referring to Figures 1 and 2 , the material roller assembly 2 further includes a first bend roller 24 and a second bend roller 25. The first bend roller 24 is rotatably connected to the mounting base 1 and is configured to convey the second release paper 103 during rotation. The second bend roller 25 is rotatably connected to the mounting base 1 and is configured to convey the second release paper 103 during rotation. A first line 901 connects the centers of the first bend roller 24 and the second bend roller 25. A second line 902 is a common tangent to the outer contours of the first bend roller 24 and the second bend roller 25. The second line 902 is located on one side of the first line 901. The first colloid detector 5 includes a detection portion 51 for detection. A straight line coinciding with the detection portion 51 and parallel to the detection direction of the detection portion 51 intersects the second line 902.

[0134] For example, referring to Figures 1 and 2 , the second release paper 103 released from the film roll 100 is sequentially wound around the first bend roller 24, the second bend roller 25, the pressure roller 3, and the second take-up roller 23. The first bend roller 24 abuts the side of the second release paper 103 facing away from the adhesive 102, while the second bend roller 25 abuts the side of the second release paper 103 facing away from the adhesive 102. When the second drive mechanism 4 drives the second take-up roller 23 to rotate, the second release paper 103 moves. The moving second release paper 103 then drives the first bend roller 24, the second bend roller 25, and the pressure roller 3 to rotate.

[0135] For example, referring to FIG. 1 and FIG. 2 , the first redirecting roller 24 and the second redirecting roller 25 are both located on the side of the pressing roller 3 facing away from the first direction.

[0136] Please refer to FIG. 2 . The second connection line 902 is located on one side of the first connection line 901 , and the second connection line 902 does not intersect with the first connection line 901 .

[0137] Please refer to Figures 1 and 2. The common tangent line of the outer contour of the first redirecting roller 24 and the outer contour of the second redirecting roller 25 is the second connecting line 902, and the second connecting line 902 is located on one side of the first connecting line 901. The second release paper 103 wrapped around the first redirecting roller 24 and the second redirecting roller 25 roughly coincides with the second connecting line 902.

[0138] Exemplarily, the detection direction of the detection unit 51 is perpendicular to the second connecting line 902 .

[0139] In the disclosed embodiment, because a straight line coinciding with the detection unit 51 and parallel to the detection direction of the detection unit 51 intersects the second line 902, the first colloid detector 5 detects the colloid 102 on the second release paper 103 coinciding with the second line 902. The arrangement of the first redirecting roller 24 and the second redirecting roller 25 changes the direction in which the second release paper 103 released from the film 100 moves toward the pressure roller 3, so that the direction of the second release paper 103 coinciding with the second line 902 toward the colloid 102 can best meet the detection requirements of the first colloid detector 5, thereby enabling the first detector to better detect the colloid 102. By adapting the direction of the second release paper 103 coinciding with the second line 902 toward the colloid 102 to the detection requirements of the first colloid detector 5, the position of the first colloid detector 5 can be arranged according to actual needs, making the position of the first colloid detector 5 more flexible.

[0140] It can be understood that the material roller assembly 2 may not be provided with the first redirecting roller 24 and the second redirecting roller 25 as appropriate.

[0141] In one embodiment, please refer to Figure 2, the center line of the second redirecting roller 25 and the pressure roller 3 is the third line 903, the angle between the first line 901 and the third line 903 is the first preset angle 904, the first preset angle 904 is less than 180°, and the rubber roller 21 is located on the side of the second redirecting roller 25 facing the first preset angle 904.

[0142] Exemplarily, the first preset angle 904 may be measured by an angle measuring device.

[0143] Exemplarily, the first preset angle 904 may be 60°, 100°, 120°, 145° or 160°.

[0144] In the embodiment of the present disclosure, since the angle between the first connecting line 901 and the third connecting line 903 is less than the first preset angle 904 of 180°, the second release paper 103 sequentially wound around the first redirecting roller 24 and the second redirecting roller 25 is arranged on the side of the second redirecting roller 25 facing the first preset angle 904 to form a certain accommodation space, and the glue roller 21 is located on the side of the second redirecting roller 25 facing the first preset angle 904. This part of the accommodation space can be fully utilized to arrange the glue roller 21, thereby improving space utilization and reducing the overall space occupied by the glue laminating device 200.

[0145] It is understood that there is no specific limitation on the position of the sizing roller 21 . The sizing roller 21 may be arranged on a side of the second redirecting roller 25 away from the first preset angle 904 .

[0146] In one embodiment, referring to Figures 1 and 2 , the material roller assembly 2 further includes a carrier roller 26 and a top roller 27 . The carrier roller 26 is rotatably connected to the mounting base 1 . The top roller 27 is rotatably connected to the mounting base 1 , and is arranged opposite the carrier roller 26 to clamp the second release paper 103 between the carrier roller 26 and the top roller 27 .

[0147] The carrier roller 26 is primarily used to support the second release paper 103, and the top roller 27 abuts against the second release paper 103 on the carrier roller 26. When the second drive mechanism 4 drives the second take-up roller 23 to rotate and move the second release paper 103, the first release paper 101 drives the carrier roller 26 and the top roller 27 to rotate.

[0148] For example, referring to Figure 1 , the second release paper 103 released from the film roll 100 is sequentially wound around the pressure roller 3, the supporting roller 26, and the second take-up roller 23. The supporting roller 26 abuts the side of the second release paper 103 facing away from the adhesive 102, while the top roller 27 abuts the side of the second release paper 103 facing toward the adhesive 102. When the second drive mechanism 4 rotates the second take-up roller 23, moving the second release paper 103, the first release paper 101 drives the supporting roller 26, the top roller 27, and the pressure roller 3 to rotate.

[0149] For example, referring to FIG. 1 , the second release paper 103 released from the film roll 100 is sequentially wound around the first redirecting roller 24 , the second redirecting roller 25 , the pressure roller 3 , the carrying roller 26 and the second receiving roller 23 .

[0150] In the embodiment of the present disclosure, the second release paper 103 is clamped by the carrying roller 26 and the top roller 27, and the second release paper 103 moving from the carrying roller 26 to the second receiving roller 23 can be tensioned, which is conducive to the second release paper 103 being wound more neatly on the second receiving roller 23.

[0151] It is understandable that the material roller assembly 2 may not be provided with the top roller 27 and the carrying roller 26 depending on the situation.

[0152] In one embodiment, please refer to Figure 2, the center line of the pressure roller 3 and the supporting roller 26 is the fourth line 905, the center line of the supporting roller 26 and the second receiving roller 23 is the fifth line 906, and the angle between the fourth line 905 and the fifth line 906 is the second preset angle 907, and the second preset angle 907 is less than 180°. The material roller assembly 2 also includes a transition roller rotatably connected to the mounting base 1, and the transition roller is located on the side of the supporting roller 26 facing the second preset angle 907.

[0153] Exemplarily, the second preset angle 907 may be measured by an angle measuring device.

[0154] Exemplarily, the second preset angle 907 may be 70°, 100°, 120°, 150° or 170°.

[0155] For example, referring to FIG1 , the second release paper 103 released from the film 100 is sequentially wound around the pressure roller 3, the transition roller, the carrying roller 26 and the second receiving roller 23 . The transition roller abuts against the side of the second release paper 103 facing the colloid 102 , and the moving second release paper 103 drives the transition roller to rotate.

[0156] In the embodiment of the present disclosure, when the pressure roller 3 and the carrying roller 26 abut against the side of the second release paper 103 facing away from the colloid 102, the transition roller abuts against the side of the second release paper 103 facing the colloid 102. Since the transition roller is located on the side of the carrying roller 26 facing the second preset angle 907, the transition roller can press the second release paper 103, so that the pressure roller 3 and the carrying roller 26 can be respectively covered with more second release paper 103, thereby increasing the belt transmission wrap angle of the second release paper 103 to the pressure roller 3 during movement, and increasing the belt transmission wrap angle of the second release paper 103 to the carrying roller 26 during movement, reducing the possibility of the second release paper 103 slipping between the pressure roller 3 or the carrying roller 26 during movement, which is conducive to the pressure roller 3 and the carrying roller 26 to better convey the second release paper 103.

[0157] It is understood that the number of transition rollers is not specifically limited. For example, there may be one or more transition rollers.

[0158] In one embodiment, please refer to Figures 1 and 2, there are two transition rollers, one of which is the first transition roller 28, and the other is the second transition roller 29. The center line between the pressure roller 3 and the first transition roller 28 is the sixth line 908, the center line between the first transition roller 28 and the second transition roller 29 is the seventh line 909, and the center line between the second transition roller 29 and the supporting roller 26 is the eighth line 910. The sixth line 908 and the eighth line 910 are both arranged to cross the seventh line 909, and the sixth line 908 and the eighth line 910 are both located on one side of the seventh line 909.

[0159] For example, referring to FIG. 1 , the second release paper 103 released from the film roll 100 is sequentially wound around the pressure roller 3 , the first transition roller 28 , the second transition roller 29 , the carrying roller 26 and the second receiving roller 23 .

[0160] 1 , the second release paper 103 released from the film 100 is sequentially wound around the first redirecting roller 24 , the second redirecting roller 25 , the pressure roller 3 , the first transition roller 28 , the second transition roller 29 , the carrying roller 26 and the second receiving roller 23 .

[0161] For example, referring to Figures 1 and 2, the first redirecting roller 24, the second redirecting roller 25, the rubber roller 21 and the first receiving roller 22 are all located on one side of the pressure roller 3 along the second direction, and the first transition roller 28, the second transition roller 29, the supporting roller 26 and the second receiving roller 23 are all located on the other side of the pressure roller 3 along the second direction, and the second direction is arranged crosswise with the first direction.

[0162] Exemplarily, referring to FIG. 1 and FIG. 2 , the second direction is the direction indicated by arrow R5 in the figures.

[0163] In the disclosed embodiment, the belt transmission wrap angle of the pressure roller 3 is increased by the first transition roller 28, and the belt transmission wrap angle of the bearing roller 26 is increased by the second transition roller 29. The position of the first transition roller 28 will not affect the belt transmission wrap angle of the bearing roller 26, and the position of the second transition roller 29 will not affect the belt transmission wrap angle of the pressure roller 3. The belt transmission wrap angle of the pressure roller 3 and the belt transmission wrap angle of the bearing roller 26 can be set independently according to actual needs.

[0164] It is understandable that the material roller assembly 2 may not be provided with a transition roller depending on circumstances.

[0165] In one embodiment, referring to FIG. 1 and FIG. 2 , the glue-applying device 200 further includes a second colloid detector 6 , which is connected to the glue-applying side of the mounting base 1 , and whose detection direction is toward the glue-applying side of the mounting base 1 .

[0166] The adhesive-coating side of the mounting base 1 , that is, the pressing roller 3 on the mounting base 1 presses the adhesive 102 toward the side of the adhesive-coating object 500 .

[0167] The detection direction of the second colloid detector 6 is toward the adhesive-applied side of the mounting base 1 , and the second colloid detector 6 can detect the colloid 102 on the adhesive-applied object 500 along the detection direction.

[0168] In the embodiment of the present disclosure, a second colloid detector 6 is provided to detect the colloid 102 on the glued object 500 and determine whether the colloid 102 is pasted at the corresponding position on the glued object 500, thereby realizing automatic detection of the glued condition on the glued object 500.

[0169] It is understandable that the glue applying device may not be provided with the second colloid detector 6 .

[0170] In one embodiment, referring to FIG. 1 to FIG. 4 , the sizing roller 21 is drivingly connected to the second driving mechanism 4 , and the second driving mechanism 4 is further used to drive the sizing roller 21 to rotate.

[0171] Exemplarily, the linear speed at which the first release paper 101 is moved by the rotation of the first receiving roller 22 is a first speed, the linear speed at which the second release paper 103 is moved by the rotation of the second receiving roller 23 is a second speed, and the speed at which the film 100 on the glue roller 21 releases the first release paper 101 and the second release paper 103 is a third speed, and the first speed, the second speed and the third speed are all approximately equal.

[0172] In the disclosed embodiment, the sizing roller 21, the first take-up roller 22 and the second take-up roller 23 are all driven by the second drive mechanism 4. The second drive mechanism 4 drives the sizing roller 21, the first take-up roller 22 and the second take-up roller 23 to rotate in coordination, so that the first release paper 101 and the second release paper 103 released from the film 100 can be better tensioned, thereby better separating and conveying the first release paper 101 and the second release paper 103.

[0173] It is understood that the sizing roller 21 can be driven independently of the second drive mechanism 4, depending on the circumstances. For example, the second drive mechanism 4 drives the first and second take-up rollers 22 and 23 to rotate, thereby correspondingly moving the first and second release papers 101 and 103. The moving first and second release papers 101 and 103 then rotate the film 100 on the sizing roller 21, causing the sizing roller 21 to rotate along with the film 100. The sizing roller 21 can be subjected to appropriate friction during rotation, so that when the first and second take-up rollers 22 and 23 stop rotating, the sizing roller 21 can also stop rotating due to the friction.

[0174] In one embodiment, the adhesive bonding object is an unused rolled current collector.

[0175] It should be noted that an unused rolled current collector refers to a rolled current collector that has not yet been unrolled and released. For example, a rolled current collector is placed on a cutting machine, and the end of the rolled current collector is pulled by a corresponding mechanism on the cutting machine to drive the rolled current collector to rotate, thereby unrolling and releasing the rolled current collector. An unused rolled current collector can be considered as a rolled current collector that has not yet been pulled by the corresponding mechanism on the cutting machine to be unrolled and released.

[0176] In the embodiment of the present disclosure, glue is applied to the unused rolled current collector so that the rolled current collector that is about to be used up can be unfolded and released and then pasted to the unused rolled current collector. After the unfolded and released current collector that is about to be used up is cut off, the unfolded current collector pasted together with the unused rolled current collector drives the unused rolled current collector to rotate under the traction of the corresponding mechanism of the cutting machine, so that the unused rolled current collector can be unfolded and released and cut by the cutting machine.

[0177] In one embodiment, there are multiple colloids, and the multiple colloids are spaced apart between the first release paper and the second release paper. The multiple colloids are spaced apart and are not continuous. After the colloids are applied, there is no need to cut the colloids, which helps simplify the application process.

[0178] The present disclosure also provides a method for applying glue, as shown in FIG5 , including:

[0179] Step S1: When the mounting base is in a pre-pressing position relative to the supporting device and has not yet been glued, the second driving mechanism drives at least the first and second take-up rollers to rotate, so that the second release paper with the first release paper removed drives the glue to move to the pressing roller;

[0180] Step S2: driving one of the supporting device and the mounting base located at the pre-pressing position closer to the other via the first driving mechanism, so that the pressing roller presses the adhesive on the second release paper toward the adhesive-coated object;

[0181] Step S3: driving one of the supporting device and the mounting base away from the other via the first driving mechanism, so that the adhesive adhered to the adhesive object is separated from the second release paper.

[0182] For example, when the colloid 102 moves to the pressure roller 3 , the second driving mechanism 4 may be turned off to keep the colloid 102 at the pressure roller 3 .

[0183] In the embodiment of the present disclosure, at the pre-pressing position, the second drive mechanism 4 drives at least the first take-up roller 22 and the second take-up roller 23 to rotate, so that the first release paper 101 is separated from the second release paper 103, and the glue 102 remains on the second release paper 103. The first drive mechanism 300 drives the mounting platform to move from the pre-pressing position to the glue pressing position, so that the glue 102 at the pressure roller 3 is pressed toward the glue-applying object 500, thereby achieving glue application. After the glue 102 is attached to the glue-applying object 500, the first drive mechanism 300 drives the mounting base 1 to move from the glue pressing position to the corresponding degumming position, so that the second release paper 103 is separated from the glue 102, thereby achieving automation of the entire glue application process. The glue 102 separated from the second release paper 103 on the glue-applying object 500 can also be attached to other objects.

[0184] In one embodiment, referring to FIG. 6 , the number of pre-pressing positions corresponding to the adhesive laminating object 500 is multiple, and the multiple pre-pressing positions are arranged in sequence. The adhesive laminating method further includes:

[0185] Step S4: When the adhesive on the adhesive object is separated from the second release paper, the first driving mechanism drives one of the support device and the mounting base to move relative to the other, so that the mounting base is located at another pre-pressing position adjacent to the reference pre-pressing position relative to the support device, and the reference pre-pressing position is the pre-pressing position corresponding to the adhesive separated from the second release paper.

[0186] Exemplarily, the plurality of pre-stressing positions are arranged along the second direction, and the second direction is arranged to intersect with the first direction.

[0187] Exemplarily, referring to FIG. 1 and FIG. 2 , the second direction is the direction indicated by arrow R5 in the figures.

[0188] In the embodiment of the present disclosure, the position where the glue 102 is pressed against the glued object 500 will change accordingly as the pre-pressing position is different. The first driving mechanism 300 drives the mounting base 1 to move from the debonding position to another pre-pressing position, thereby realizing sequential and spaced gluing at multiple different positions on the glued object 500.

[0189] In one embodiment, referring to FIG6 , one of the pre-pressing positions is the target position, and among all the pre-pressing positions, except the target position, the other pre-pressing positions are located on one side of the target position. The adhesive application method further includes:

[0190] Step S5: driving one of the mounting base and the supporting device to move relative to the other via the first driving mechanism, so that the mounting base is at a target position relative to the supporting device.

[0191] Exemplarily, referring to FIG. 1 and FIG. 2 , the mounting base 1 is moved one by one from the target position to the adjacent pre-pressing position along the second direction.

[0192] In the embodiment of the present disclosure, the mounting base 1 moves to the target position, and the other pre-pressing positions except the target position are all located on one side of the target position. When the mounting base 1 is at the target position and the corresponding gluing steps are performed, the mounting base 1 will move to the pre-pressing position adjacent to the target position among the other pre-pressing positions, until the mounting base 1 moves from the target position to the side where the other pre-pressing positions are located, and all the colloids 102 at all the pre-pressing positions are pasted. The mounting base 1 can complete the gluing at all the pre-pressing positions by moving in one direction starting from the target position, which is beneficial to shortening the moving path of the mounting base 1 during the gluing process.

[0193] In one embodiment, referring to FIG6 , when the mounting base 1 is in a pre-pressing position relative to the supporting device 400 and has not yet been glued, the second driving mechanism 4 drives at least the first and second take-up rollers 22 and 23 to rotate, so that the second release paper 103 removed from the first release paper 101 drives the glue 102 to move to the pressing roller 3, including:

[0194] Step S11: When the first colloid detector detects the colloid on the second release paper during the process of the second driving mechanism driving at least the first and second colloid rollers to rotate, the second driving mechanism drives at least the first and second colloid rollers to rotate to drive the second release paper to move a preset distance, so that the corresponding colloid moves to the pressure roller.

[0195] For example, the preset distance can be obtained through repeated debugging or theoretical calculation.

[0196] In the embodiment of the present disclosure, the position on the second release paper 103 detected by the first colloid detector 5 is fixed. Along the path along which the second release paper 103 is wound, the distance from the position on the second release paper 103 detected by the first colloid detector 5 to the pressure roller 3 is approximately a preset distance, and this preset distance basically does not change. Therefore, when the first colloid detector 5 detects that the colloid 102 is triggered, the second release paper 103 moves the preset distance, which can drive the corresponding colloid 102 to move the preset distance, thereby allowing the colloid 102 to move to the pressure roller 3 more accurately.

[0197] Please refer to FIG7 , and the adhesive application method will be described in detail through the following embodiments.

[0198] Step S101: starting to change the rolled current collector;

[0199] Step S102: driving the glue application device to move to a target position via a first driving mechanism;

[0200] Step S103: driving the sizing roller, the first receiving roller, and the second receiving roller to rotate by the second driving mechanism, so that the second release paper removed from the first release paper drives the colloid to move to the pressing roller;
