The entire content of the Chinese patent application is hereby introduced into the present disclosure as a reference. Technical Field

[0003] The present disclosure relates to the technical field of battery manufacturing, and in particular to a paper tearing device, a paper tearing method, a glue sticking device, and a glue sticking method. Background Art

[0004] New energy batteries are being used more and more widely in life and industry. For example, new energy vehicles equipped with batteries have been widely used. In addition, batteries are also being increasingly used in energy storage fields.

[0005] A battery module is composed of multiple battery cells. During the production and manufacturing process of the battery module, especially during the battery grouping process, it is usually necessary to stick thermal insulation pads or double-sided tape on the battery cells. Improving the efficiency of the sticking is an important part of improving the efficiency of battery module assembly. The sticking process of the thermal insulation pad or double-sided tape requires first tearing off the release paper, then checking whether the release paper is completely torn off, and then sticking the completely exposed adhesive surface to the battery cell. Therefore, improving the efficiency of release paper detection is one of the important measures to improve the efficiency of the sticking process.

[0006] In addition, since battery modules usually include multiple models, the insulation pads or double-sided tapes that need to be removed from the release paper have various specifications. Therefore, how to improve the compatibility of release paper detection without reducing the efficiency of release paper detection is one of the research topics in the industry.

[0007] Summary of the Invention

[0008] In order to solve the above technical problems, the present disclosure provides a paper tearing device, a paper tearing method, a gluing device and a gluing method, which are used to improve the compatibility of release paper detection without reducing the release paper detection efficiency.

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

[0010] A first aspect of the present disclosure provides a paper-tearing device for performing a paper-tearing operation on at least two sheets, the sheets having an adhesive surface covered by a release paper, the paper-tearing operation comprising a paper-tearing action of tearing the release paper from the adhesive surface and a detection action of detecting whether the release paper is completely torn off after the paper-tearing action; the paper-tearing device comprises: a base; a paper-tearing mechanism, arranged on the base, the paper-tearing mechanism being used to perform the paper-tearing action on at least two sheets arranged in sequence along a first direction; a first detection camera, arranged on the base; a second detection camera, arranged on the base and located on one side of the first detection camera along the first direction, the first detection camera and the second detection camera being configured to be able to approach or move away from each other so that each of the sheets is within the shooting field of view of the first detection camera and the second detection camera; the first detection camera and the second detection camera being configured to jointly perform the detection action on a plurality of the sheets.

[0011] When using the paper tearing device to perform paper tearing operations, the paper tearing mechanism tears at least two sheets arranged in sequence along the first direction, and the first detection camera and the second detection camera approach or move away from each other, so that each sheet is within the shooting field of view of the first detection camera and the second detection camera, and the first detection camera and the second detection camera jointly perform detection actions on multiple sheets.

[0012] The first detection camera and the second detection camera can detect multiple sheets at the same time, which can improve the efficiency of release paper detection. When replacing a sheet with a larger specification and performing a paper tearing operation on the sheet with a larger specification, the distance between the first detection camera and the second detection camera can be increased, and the shooting field of view of the first detection camera and the second detection camera can be increased, so that at least two sheets are located within the shooting field of view, thereby improving the compatibility of release paper detection without reducing the efficiency of release paper detection. Moreover, when replacing a sheet with a smaller specification and performing a paper tearing operation on the sheet with a smaller specification, the distance between the first detection camera and the second detection camera can be reduced, and the shooting field of view of the first detection camera and the second detection camera can be reduced, and the overlapping shooting field of view of the first detection camera and the second detection camera can be increased. In this way, the sheets located in the overlapping shooting fields of view are detected separately by the first detection camera and the second detection camera, which is conducive to improving the accuracy of detection.

[0013] In some embodiments, the shooting field of view of the first detection camera is a first shooting field of view, and the shooting field of view of the second detection camera is a second shooting field of view. The first shooting field of view and the second shooting field of view together form a shooting range, and the first shooting field of view and the second shooting field of view have an overlapping part, and each of the sheets is within the shooting range.

[0014] The first field of view of the first detection camera and the second field of view of the second detection camera overlap, creating a continuous capture range. This reduces the possibility of detection accuracy being affected by a gap between the first and second fields of view. Furthermore, at least a portion of the sheets can be positioned within the overlap between the first and second fields of view. Thus, sheets within the overlap are simultaneously inspected by the first and second detection cameras, which improves detection accuracy.

[0015] In some embodiments, the first detection camera and the second detection camera are moved closer to or farther away from each other so that a midpoint between the first detection camera and the second detection camera is located within a median plane of an area occupied by all the sheets.

[0016] In this way, the first detection camera and the second detection camera can achieve a state of center alignment with all sheets by moving closer to or further away from each other, so that the first detection camera and the second detection camera can increase the overlapping part of the first shooting field of view and the second shooting field of view as much as possible while being able to capture all sheets, which is further beneficial to improve the accuracy of detection.

[0017] In some embodiments, the paper tearing device also includes a control module, which determines the position of the center dividing surface based on the position and size of the sheet in the first direction, and calculates the distance that the first detection camera and / or the second detection camera need to move based on the positions of the first detection camera and the second detection camera, and controls the movement of the first detection camera and / or the second detection camera.

[0018] The setting of the control module realizes the automation of the movement control of the first detection camera and / or the second detection camera, thereby improving the accuracy and efficiency of the position adjustment of the first detection camera and / or the second detection camera.

[0019] In some embodiments, along the first direction, the sheet at the first position is the first sheet, the sheet at the end is the second sheet, the end surface of the first sheet facing away from the second sheet is the first reference surface, the end surface of the second sheet facing away from the first sheet is the second reference surface, and the plane located in the middle position between the first reference surface and the second reference surface is the center dividing surface; the control module calculates the position of the center dividing surface based on the positions of the first reference surface and the second reference surface.

[0020] The distance between the first reference surface and the second reference surface is the total length of the area where all sheets are located in the first direction. The position of the midpoint of the total length can be accurately calculated, thereby improving the accuracy of determining the mid-dividing surface.

[0021] In some embodiments, the first detection camera is fixedly mounted on the base, and the second detection camera is mounted on the base and is movable along the first direction.

[0022] In this way, the structure of the connector connecting the first detection camera and the base can be simplified, reducing material costs. Moreover, only the position of one camera needs to be adjusted, and the movement position is easy to control and easy to operate.

[0023] In some embodiments, the paper tearing device further includes a lighting lamp, which is disposed on the base and whose lighting range includes the shooting range.

[0024] The lighting range of the lighting lamp includes the shooting range, so that the lighting lamp can provide a sufficient light field for the first detection camera and the second detection camera, thereby facilitating improving the accuracy of detection.

[0025] In some embodiments, the paper tearing mechanism includes a clamp, and the clamp includes a plurality of clamping components sequentially arranged along the first direction, and the plurality of clamping components are used to clamp the release paper of the plurality of sheets in a one-to-one correspondence.

[0026] The multiple clamping assemblies are used to clamp the release papers of the multiple sheets in a one-to-one correspondence, so that the paper tearing mechanism can tear off the release papers of the multiple sheets at the same time, thereby improving the paper tearing efficiency.

[0027] In some embodiments, the clamping assembly includes: a connecting member, which is arranged on the base; a first clamping plate, which is arranged on the connecting member; and a second clamping plate, which is arranged on the connecting member; wherein the first clamping plate and the second clamping plate can move closer to or farther away from each other to clamp or loosen the release paper.

[0028] The clamping surface of the first clamping plate and the second clamping plate is relatively large. For some release papers that are skewed and warped, the first clamping plate and the second clamping plate with a larger clamping surface can still clamp them. Therefore, the clamping assembly improves compatibility and reduces the occurrence of some situations where the release paper cannot be clamped and cannot be torn off.

[0029] In some embodiments, the clamping assembly further includes a second driving member, which is disposed on the connecting member and is configured to drive the first clamping plate and / or the second clamping plate to move closer to or away from each other.

[0030] The second driving member is used to provide power for the movement of the first clamping plate and / or the second clamping plate.

[0031] In some embodiments, a plurality of the connecting members are connected to each other to form a connecting frame.

[0032] One connecting frame connects a plurality of first clamping plates and a plurality of second clamping plates at the same time, so that the structure is simple, the structural strength is high, and the assembly operation is simple.

[0033] In some embodiments, the first clamping plate is fixedly connected to the connecting member, and the second clamping plate can be driven by a second driving member to move closer to or away from the first clamping plate.

[0034] The first clamping plate is fixedly connected to the connecting piece, which simplifies the structure of the components connecting the first clamping plate and the connecting piece and reduces material costs. Moreover, only the position of one clamping plate needs to be adjusted, and the moving position is easy to control and easy to operate.

[0035] In some embodiments, the paper tearing mechanism further includes a moving mechanism, the moving mechanism is disposed on the base, the clamp is connected to the moving mechanism, and the moving mechanism is configured to drive the clamp to approach or move away from the sheet.

[0036] In this way, the moving mechanism is used to drive the clamp to move, and the moving mechanism cooperates with the clamp to complete the paper tearing operation.

[0037] In some embodiments, the movement mechanism comprises a multi-axis robot.

[0038] The multi-axis robot has the characteristics of repeatable programming, automatic control, multiple degrees of freedom, etc. The mobile fixture has high precision, which improves the success rate of paper tearing.

[0039] In some embodiments, the sheet has a first adhesive surface and a second adhesive surface, the release paper covers the second adhesive surface, and the tearing mechanism is used to perform the tearing action on the sheet adhered to the first adhesive component through the first adhesive surface to tear off the release paper covering the second adhesive surface.

[0040] The paper tearing device is used to tear off the release paper on the second side of the sheet material adhered to the first adhesive component.

[0041] In some embodiments, the paper tearing device further includes a positioning mechanism for positioning the first adhesive component, the positioning mechanism including at least two positioning structures spaced apart in sequence along the first direction, each positioning structure being used to limit the position of the first adhesive component in a one-to-one correspondence.

[0042] The positioning mechanism is used to position the at least two first adhesive components, thereby defining the positions of the sheets adhered to the at least two first adhesive components, so that the at least two sheets are sequentially spaced along a first direction. In this manner, the at least two clamping assemblies of the clamp can clamp the release paper of the at least two sheets in a one-to-one correspondence, and during the paper tearing operation, the positioned sheets do not move with the clamp, thereby smoothly tearing the release paper from the sheets.

[0043] In some embodiments, the positioning structure includes a bearing portion, a positioning block and a pushing block, the bearing portion defines a bearing area, the positioning block and the pushing block are respectively arranged on opposite sides of the bearing area along the first direction, and the pushing block is configured to be able to approach or move away from the corresponding positioning block along the first direction to clamp or loosen the first adhesive component located in the bearing area.

[0044] In this way, the positioning function of the positioning structure on the first adhesive component is realized, and the positioning structure has a simple structure and a simple assembly process.

[0045] In some embodiments, the first adhesive component includes a battery cell, and the sheet material includes a thermal insulation pad.

[0046] The disclosed embodiments can be applied to the process of pasting thermal insulation pads on battery cells. Since the first detection camera and the second detection camera can detect multiple thermal insulation pads at the same time, the release paper detection efficiency can be improved. When replacing a larger thermal insulation pad and performing a paper tearing operation on the larger thermal insulation pad, the distance between the first detection camera and the second detection camera can be increased, and the shooting field of view of the first detection camera and the second detection camera can be increased, so that at least two thermal insulation pads are located within the shooting field of view, thereby improving the compatibility of release paper detection without reducing the release paper detection efficiency. Moreover, when replacing a smaller thermal insulation pad and performing a paper tearing operation on the smaller thermal insulation pad, the distance between the first detection camera and the second detection camera can be reduced, and the shooting field of view of the first detection camera and the second detection camera can be reduced, and the overlapping shooting field of view of the first detection camera and the second detection camera can be increased. In this way, the thermal insulation pads located in the overlapping shooting fields of view are detected separately by the first detection camera and the second detection camera, which is conducive to improving the detection accuracy.

[0047] A second aspect of the present disclosure provides a paper tearing method, which uses a paper tearing device to tear a sheet of material, wherein the sheet has an adhesive surface covered by a release paper, and the paper tearing device includes a base, a paper tearing mechanism, a first detection camera, and a second detection camera. The paper tearing method includes: a paper tearing action, in which the paper tearing mechanism tears off the release paper covering the adhesive surface of a plurality of sheets arranged in sequence along a first direction; a detection preparation action, in which the first detection camera and / or the second detection camera moves a set distance so that each of the sheets is within the shooting field of view of the first detection camera and / or the second detection camera; a detection action, in which the first detection camera and the second detection camera jointly shoot the plurality of sheets that have completed the paper tearing action and detect whether the release paper is completely torn off based on the shot images.

[0048] In the paper tearing method, the first detection camera and the second detection camera simultaneously detect multiple sheets by moving closer or farther away, thereby improving the compatibility of release paper detection without reducing the release paper detection efficiency, and also helping to improve detection accuracy.

[0049] The third aspect of the present disclosure provides a gluing method, which uses a gluing device to stick a sheet to a gluing component, wherein the sheet has an adhesive surface covered by a release paper, the gluing device includes a paper tearing device and a gluing device, the paper tearing device includes a base, a paper tearing mechanism, a first detection camera and a second detection camera, and the gluing method includes: a paper tearing action, wherein the paper tearing mechanism tears off the release paper covering the adhesive surface of multiple sheets arranged in sequence along a first direction; a detection preparation action, wherein the first detection camera and / or the second detection camera moves a set distance so that each of the sheets is within the shooting field of view of the first detection camera and / or the second detection camera; a detection action, wherein the first detection camera and the second detection camera jointly shoot the multiple sheets that have completed the paper tearing action and detect whether the release paper is completely torn off based on the shot image; and a gluing action, wherein the gluing device sticks the sheet from which the release paper is detected to be completely torn off to the gluing component through the adhesive surface.

[0050] In this gluing method, the first detection camera and the second detection camera can simultaneously detect multiple sheets by moving closer or farther away, thereby improving the compatibility of release paper detection without reducing release paper detection efficiency, and is also conducive to improving detection accuracy.

[0051] The fourth aspect of the present disclosure provides a glue-applying device, comprising: a first-side paper-tearing device, used to tear off the release paper on one side of a sheet to expose a first adhesive surface; a first-side pasting device, used to past the sheet to a first glue-applying component through the first adhesive surface; the above-mentioned paper-tearing device as a second-side paper-tearing device, the paper-tearing device being used to perform the paper-tearing operation on the sheet to tear off the other side of the release paper to expose the second adhesive surface; and a second-side pasting device, used to past the sheet to a second glue-applying component through the second adhesive surface.

[0052] The gluing device provided in the embodiments of the present disclosure is used to affix a sheet material between a first gluing component and a second gluing component. Because the gluing device includes the aforementioned paper tearing device, it includes all the benefits of the aforementioned paper tearing device. Therefore, the gluing device improves the compatibility of release paper detection without reducing the efficiency of release paper detection, and improves the accuracy of detection.

In this method, the first and second inspection cameras simultaneously inspect multiple sheets by moving closer or further apart, thereby improving the compatibility of release paper inspection without reducing release paper inspection efficiency, and further facilitating improved inspection accuracy.

[0079] Hereinafter, the present disclosure will be described in detail.

[0080] Currently, new energy batteries are increasingly being used in everyday life and industry. They are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric cars, as well as in a variety of fields such as aerospace. As the application of power batteries continues to expand, market demand is also growing.

[0081] A battery module is composed of multiple battery cells. During the production and manufacturing process of the battery module, especially during the battery grouping process, it is usually necessary to stick thermal insulation pads or double-sided tape on the battery cells. Improving the efficiency of the sticking is an important part of improving the efficiency of battery module assembly. The sticking process of the thermal insulation pad or double-sided tape requires first tearing off the release paper, then checking whether the release paper is completely torn off, and then sticking the completely exposed adhesive surface to the battery cell. Therefore, improving the efficiency of release paper detection is one of the important measures to improve the efficiency of the sticking process.

[0082] In addition, since battery modules usually include multiple models, the insulation pads or double-sided tapes that need to be removed from the release paper have various specifications. Therefore, how to improve the compatibility of release paper detection without reducing the efficiency of release paper detection is one of the research topics in the industry.

[0083] The inventors of the present disclosure have noticed that, at present, in order to improve the grouping efficiency, the traditional method is to perform grouping operations on at least two battery modules at the same time. That is, during the grouping process, a detection camera is used to detect at least two thermal insulation pads or double-sided tapes at the same time. However, if the specifications of the thermal insulation pads or double-sided tapes change, for example, the thermal insulation pads or double-sided tapes extend out of the field of view of the detection camera, the detection camera cannot detect all the thermal insulation pads or double-sided tapes at the same time, which will affect the efficiency of release paper detection.

[0084] After research, the inventors of this disclosure discovered that using two inspection cameras with adjustable spacing instead of a traditional inspection camera with a fixed and smaller field of view can achieve an adjustable field of view. If the specifications of the thermal pad or double-sided tape change, the spacing between the two inspection cameras can be adaptively adjusted to adjust the field of view, so that the field of view includes at least two thermal pads or double-sided tapes. This allows for simultaneous inspection of at least two thermal pads or double-sided tapes, thereby improving the compatibility of release paper inspection without reducing release paper inspection efficiency.

[0085] Based on such a design concept, the inventor of the present disclosure designed a paper tearing device for tearing at least two sheets of material, wherein the sheet has an adhesive surface covered by release paper, and the paper tearing operation includes a paper tearing action of tearing the release paper from the adhesive surface and a detection action of detecting whether the release paper is completely torn off after the paper tearing action; the paper tearing device includes a base, a paper tearing mechanism, a first detection camera and a second detection camera, the paper tearing mechanism is arranged on the base, and the paper tearing mechanism is used to tear at least two sheets of material arranged in sequence along a first direction; the first detection camera is arranged on the base; the second detection camera is arranged on the base and is located on one side of the first detection camera along the first direction, the first detection camera and the second detection camera are configured to be able to approach or move away from each other, so that each sheet is within the shooting field of view of the first detection camera and the second detection camera; the first detection camera and the second detection camera are configured to jointly perform detection actions on multiple sheets of material.

[0086] When using the paper tearing device to perform paper tearing operations, the paper tearing mechanism tears at least two sheets arranged in sequence along the first direction, and the first detection camera and the second detection camera approach or move away from each other, so that each sheet is within the shooting field of view of the first detection camera and the second detection camera, and the first detection camera and the second detection camera jointly perform detection actions on multiple sheets.

[0087] When replacing a larger thermal insulation pad or double-sided tape and performing a paper tearing operation on the larger thermal insulation pad or double-sided tape, the distance between the two detection cameras can be increased, and the shooting field of view of the two detection cameras can be increased, so that at least two thermal insulation pads or double-sided tapes are located within the shooting field of view, thereby improving the compatibility of release paper detection without reducing the efficiency of release paper detection. In addition, when replacing a smaller thermal insulation pad or double-sided tape and performing a paper tearing operation on the smaller thermal insulation pad or double-sided tape, the distance between the two detection cameras can be reduced, and the shooting field of view of the two detection cameras can be reduced, and the shooting field of view of the two detection cameras can be increased. In this way, the thermal insulation pad or double-sided tape located in the overlapping shooting field of view is detected separately by the two detection cameras, which is conducive to improving detection accuracy.

[0088] The paper tearing device of the embodiment of the present disclosure can be used in the battery module grouping process, for example, to tear off the release paper from the thermal insulation pad or double-sided tape that needs to be attached to the battery cell. Of course, those skilled in the art should understand that the paper tearing device provided by the embodiment of the present disclosure is not only used for tearing off the various sheets in the battery module grouping process, but can also be used for tearing off other sheets that need to have their release paper removed.

[0089] A battery cell refers to a basic unit that can realize the mutual conversion of chemical energy and electrical energy. It can be used to make battery modules or battery packs, which are used to power electrical devices.

[0090] The battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be recharged to activate the active material after the battery cell is discharged and can be used continuously.

[0091] 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., which are not limited in the embodiments of the present disclosure.

[0092] In the embodiment of the present disclosure, the battery can be a single physical module including one or more battery cells to provide higher voltage and capacity.

[0093] In some embodiments, the battery may be a battery module. When there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0094] In some embodiments, the battery may be a battery pack, which includes a case and battery cells, wherein the battery cells or battery modules are housed in the case.

[0095] Hereinafter, some embodiments of the present disclosure will be described in detail with reference to FIG. 1 to FIG. 6 .

[0097] In some embodiments of the present disclosure, for ease of explanation, a first direction, a second direction, and a third direction are set, and the first direction, the second direction, and the third direction are directions that intersect with each other, where intersecting with each other includes intersecting perpendicularly with each other. For ease of understanding the embodiments of the present disclosure, in the embodiments shown in Figures 1 to 11, the first direction, the second direction, and the third direction are directions that intersect with each other perpendicularly for explanation, but those skilled in the art should understand that the embodiments of the present disclosure are not limited to the case where the three directions intersect with each other perpendicularly. For ease of explanation, as shown by the arrows in Figures 1 to 3, Figure 6, and Figure 8, the direction of arrow X is the first direction, the direction of arrow Y is the second direction, and the direction of arrow Z is the third direction. Sometimes the direction indicated by arrow Z along the third direction is also referred to as "above", and the opposite direction is referred to as "below".

[0098] As shown in Figures 1 and 2, the first aspect of the present disclosure provides a paper tearing device for tearing at least two sheets 100, wherein the sheet 100 has an adhesive surface covered by release paper, and the paper tearing operation includes a tearing action of tearing the release paper from the adhesive surface and a detection action of detecting whether the release paper is completely torn off after the tearing action; the paper tearing device includes a base 1, a paper tearing mechanism 2, a first detection camera 3 and a second detection camera 4, the paper tearing mechanism 2 is arranged on the base 1, and the paper tearing mechanism 2 is used to tear at least two sheets 100 arranged in sequence along a first direction; the first detection camera 3 is arranged on the base 1; the second detection camera 4 is arranged on the base 1 and is located on one side of the first detection camera 3 along the first direction, the first detection camera 3 and the second detection camera 4 are configured to be able to approach or move away from each other, so that each sheet 100 is within the shooting field of view of the first detection camera 3 and the second detection camera 4; the first detection camera 3 and the second detection camera 4 are configured to jointly perform detection actions on multiple sheets 100.

[0099] The sheet 100 is a sheet-like object having an adhesive surface on at least one side, and the adhesive surface is covered with release paper. For example, the sheet 100 may have an adhesive surface on only one side, and the adhesive surface is covered with release paper. The sheet 100 may also have adhesive surfaces on both sides. In the case of having adhesive surfaces on both sides, the sheet 100 may have one adhesive surface with the release paper torn off and pasted on the adhesive component, and the other adhesive surface is covered with release paper, and the tearing device provided in the embodiment of the present disclosure is used to tear off the release paper; the sheet 100 may also have two adhesive surfaces covered with release paper, and the tearing device provided in the embodiment of the present disclosure is used to tear off only one of the release papers, or to tear off both release papers in sequence. The sheet 100 may be an adhesive material (such as double-sided tape) used only to bond two components, or it may be an adhesive material with an adhesive function and other functions, such as but not limited to a thermal insulation pad with a heat insulation function, a thermal conductive pad with a heat conduction function, an insulating pad with an insulation function, and the like.

[0100] The base 1 is used to mount the paper tearing mechanism 2, the first detection camera 3, and the second detection camera 4, forming a single integrated structure. The base 1 can be a block or a frame. For example, the frame serving as the base 1 includes a top plate and several support rods extending along a third direction. The top plate is connected to the top ends of the support rods, the paper tearing mechanism 2 is connected to the top plate, and the first detection camera 3 and the second detection camera 4 are connected to the sides of the support rods.

[0101] The first detection camera 3 and the second detection camera 4 are both cameras for taking pictures and detecting whether the release paper is completely torn off based on the pictures taken. The specific structure and working principle can be referred to the existing technology and will not be described in detail here.

[0102] "The first detection camera 3 and the second detection camera 4 are configured to be able to move closer to or farther away from each other" means that the distance between the first detection camera 3 and the second detection camera 4 is adjustable. The first detection camera 3 may not move, and the second detection camera 4 may move closer to or farther away from the first detection camera 3; the second detection camera 4 may not move, and the first detection camera 3 may move closer to or farther away from the second detection camera 4; or both the first detection camera 3 and the second detection camera 4 may move, and the first detection camera 3 and the second detection camera 4 may move toward or away from each other respectively.

[0103] When using the paper tearing device to perform paper tearing operations, the paper tearing mechanism 2 performs a paper tearing action on at least two sheets 100 arranged in sequence along the first direction, and the first detection camera 3 and the second detection camera 4 approach or move away from each other, so that each sheet 100 is within the shooting field of view of the first detection camera 3 and the second detection camera 4, and the first detection camera 3 and the second detection camera 4 jointly perform a detection action on multiple sheets 100.

[0104] The first detection camera 3 and the second detection camera 4 can simultaneously detect multiple sheets 100, which can improve the efficiency of release paper detection. When replacing a larger sheet 100 and performing a paper tearing operation on the larger sheet 100, the distance between the first detection camera 3 and the second detection camera 4 can be increased, and the shooting field of view of the first detection camera 3 and the second detection camera 4 can be increased, so that at least two sheets 100 are located within the shooting field of view, thereby improving the compatibility of release paper detection without reducing the efficiency of release paper detection. Moreover, when replacing a smaller sheet 100 and performing a paper tearing operation on the smaller sheet 100, the distance between the first detection camera 3 and the second detection camera 4 can be reduced, and the shooting field of view of the first detection camera 3 and the second detection camera 4 can be reduced, and the overlapping shooting field of view of the first detection camera 3 and the second detection camera 4 can be increased. In this way, the sheets 100 located in the overlapping shooting fields of view are detected separately by the first detection camera 3 and the second detection camera 4, thereby helping to improve detection accuracy.

[0105] In some embodiments of the present disclosure, the shooting field of view of the first detection camera 3 is the first shooting field of view, and the shooting field of view of the second detection camera 4 is the second shooting field of view. The first shooting field of view and the second shooting field of view together form a shooting range, and the first shooting field of view and the second shooting field of view have an overlapping part, and each sheet 100 is within the shooting range.

[0106] It should be noted that the first shooting field of view refers to the field of view that the first detection camera 3 can capture when the first detection camera 3 and the second detection camera 4 are close to or far away from each other to a position suitable for capturing all sheets 100, and the second shooting field of view refers to the field of view that the second detection camera 4 can capture when the first detection camera 3 and the second detection camera 4 are close to or far away from each other to a position suitable for capturing all sheets 100.

[0107] The first field of view of the first inspection camera 3 overlaps with the second field of view of the second inspection camera 4, creating a continuous imaging range. This reduces the possibility that a gap between the first and second fields of view could affect detection accuracy. Furthermore, at least a portion of the sheets 100 can be positioned within the overlapping portion of the first and second fields of view. Thus, the sheets 100 within the overlapping portion are simultaneously inspected by the first and second inspection cameras 3 and 4, thereby improving detection accuracy.

[0108] In some embodiments of the present disclosure, the first detection camera 3 and the second detection camera 4 are moved closer to or farther away from each other so that the midpoint between the first detection camera 3 and the second detection camera 4 is located within the median plane γ of the area occupied by all sheets 100 .

[0109] For ease of understanding, the median plane γ of the area occupied by all sheets 100 is explained here: as shown in Figure 3, along the first direction, the sheet 100 located at the first position is the first sheet 100a, and the sheet 100 located at the end is the second sheet 100b. The end surface of the first sheet 100a facing away from the second sheet 100b is the first reference plane α, and the end surface of the second sheet 100b facing away from the first sheet 100a is the second reference plane β. The plane located in the middle position between the first reference plane α and the second reference plane β is the median plane γ of the area occupied by all sheets 100.

[0110] In this way, the first detection camera 3 and the second detection camera 4 can achieve a state of center alignment with all sheets 100 by moving closer to or further away from each other, so that the first detection camera 3 and the second detection camera 4 can increase the overlapping part of the first shooting field of view and the second shooting field of view as much as possible while being able to capture all sheets 100, which is further beneficial to improve the accuracy of detection.

[0111] In some embodiments of the present disclosure, the paper tearing device also includes a control module, which determines the position of the center dividing plane γ based on the position and size of the sheet 100 in the first direction, and calculates the distance that the first detection camera 3 and / or the second detection camera 4 need to move based on the positions of the first detection camera 3 and the second detection camera 4, and controls the movement of the first detection camera 3 and / or the second detection camera 4.

[0112] The setting of the control module realizes the automation of the movement of the first detection camera 3 and / or the second detection camera 4, thereby improving the accuracy and efficiency of the position adjustment of the first detection camera 3 and / or the second detection camera 4.

[0113] In some embodiments of the present disclosure, as shown in Figure 3, along the first direction, the sheet 100 located at the first position is the first sheet 100a, and the sheet 100 located at the end is the second sheet 100b. The end surface of the first sheet 100a that is away from the second sheet 100b is the first reference surface α, and the end surface of the second sheet 100b that is away from the first sheet 100a is the second reference surface β. The plane located at the middle position between the first reference surface α and the second reference surface β is the center dividing surface γ; the control module calculates the position of the center dividing surface γ according to the positions of the first reference surface α and the second reference surface β.

[0114] It can be understood that the position of the mid-plane γ is not limited to being determined by the first reference plane α and the second reference plane β, but can also be determined by any other two surfaces symmetrical about the mid-plane γ. For example, it can be determined by the end surface of the first sheet 100a facing the second sheet 100b and the end surface of the second sheet 100b facing the first sheet 100a.

[0115] The distance between the first reference plane α and the second reference plane β is the total length of the area where all sheets 100 are located in the first direction. In this way, the position of the midpoint of the total length can be accurately calculated, thereby accurately determining the median plane γ of the area where all sheets 100 are located.

[0116] In some embodiments of the present disclosure, the first detection camera 3 is fixedly disposed on the base 1 , and the second detection camera 4 is disposed on the base 1 and is movable along a first direction.

[0117] In this way, the structure of the connector connecting the first detection camera 3 and the base 1 can be simplified, reducing material costs. Moreover, only the position of one camera needs to be adjusted, and the movement position is easy to control and easy to operate.

[0118] In some embodiments of the present disclosure, the paper tearing device also includes a camera mounting structure 5 and a first driving member 7. The first driving member 7 is arranged on the base 1. The second detection camera 4 is connected to the output end of the first driving member 7 through the camera mounting structure 5. The output end of the first driving member 7 is used to drive the second detection camera 4 to move back and forth along the first direction.

[0119] The arrangement of the camera mounting structure 5 and the first driving member 7 enables the second detection camera 4 to be movably mounted on the base 1 .

[0120] In some embodiments of the present disclosure, the first driving member 7 includes a servo motor.

[0121] The servo motor facilitates changing the driving stroke, thereby facilitating adjusting the moving stroke of the second detection camera 4 .

[0122] In some embodiments of the present disclosure, the paper tearing device further includes a lighting lamp 8 , which is disposed on the base 1 and whose lighting range includes the shooting range.

[0123] The lighting range of the lighting lamp 8 includes the shooting range, so that the lighting lamp 8 can provide a sufficient light field for the first detection camera 3 and the second detection camera 4, thereby facilitating improved detection accuracy.

[0124] In some embodiments of the present disclosure, as shown in Figures 1, 4 and 5, the paper tearing mechanism 2 includes a clamp 21, and the clamp 21 includes a plurality of clamping components 211 arranged in sequence along a first direction. The plurality of clamping components 211 are used to clamp the release paper of multiple sheets 100 in a one-to-one correspondence.

[0125] The multiple clamping assemblies 211 are used to clamp the release papers of the multiple sheets 100 in a one-to-one correspondence, so that the paper tearing mechanism 2 can tear off the release papers of the multiple sheets 100 at the same time, thereby improving the paper tearing efficiency.

[0126] In some embodiments of the present disclosure, the clamping assembly 211 includes a connecting member, a first clamping plate 2111 and a second clamping plate 2112, the connecting member is arranged on the base 1; the first clamping plate 2111 is arranged on the connecting member; the second clamping plate 2112 is arranged on the connecting member; wherein the first clamping plate 2111 and the second clamping plate 2112 can be close to or away from each other to clamp or loosen the release paper.

[0127] "The first splint 2111 and the second splint 2112 can move closer to or farther away from each other" means that the distance between the first splint 2111 and the second splint 2112 can be reduced or increased. The first splint 2111 can remain stationary, and the second splint 2112 can move toward or away from the first splint 2111. The second splint 2112 can remain stationary, and the first splint 2111 can move toward or away from the second splint 2112. The first splint 2111 and the second splint 2112 can both move, and the first splint 2111 and the second splint 2112 can move toward or away from each other respectively.

[0128] It can be understood that the first clamping plate 2111 and the second clamping plate 2112 are both plate-shaped structures, and the large surfaces of the first clamping plate 2111 and the second clamping plate 2112 serve as clamping surfaces to clamp the release paper.

[0129] The clamping surfaces of the first clamping plate 2111 and the second clamping plate 2112 are relatively large. For some release papers that are skewed and warped, the first clamping plate 2111 and the second clamping plate 2112 with larger clamping surfaces can still clamp them. Therefore, the clamping assembly 211 improves compatibility and reduces the occurrence of some situations where the release paper cannot be clamped and cannot be torn off.

[0130] In some embodiments of the present disclosure, anti-slip tooth structures are provided on the clamping surfaces of the first clamping plate 2111 and the second clamping plate 2112 .

[0131] The anti-slip tooth-shaped structure is used to prevent the release paper clamped between the first clamping plate 2111 and the second clamping plate 2112 from sliding out, thereby improving the success rate of paper tearing.

[0132] In some embodiments of the present disclosure, the clamping assembly 211 further includes a second driving member 2113, which is disposed on the connecting member and configured to drive the first clamping plate 2111 and / or the second clamping plate 2112 toward or away from each other.

[0133] The second driving member 2113 is used to provide power for the movement of the first clamping plate 2111 and / or the second clamping plate 2112 .

[0134] In some embodiments of the present disclosure, the first clamping plate 2111 is fixedly connected to the connecting member, and the second clamping plate 2112 can be driven by the second driving member 2113 to move closer to or away from the first clamping plate 2111 .

[0135] The first clamping plate 2111 is fixedly connected to the connecting piece, which simplifies the structure of the components connecting the first clamping plate 2111 and the connecting piece and reduces material costs. Moreover, only the position of one clamping plate needs to be adjusted, and the moving position is easy to control and easy to operate.

[0136] In some embodiments of the present disclosure, the second driving member 2113 includes a cylinder or a linear motor.

[0137] In some embodiments of the present disclosure, a plurality of connecting members are connected to each other to form a connecting frame 212 .

[0138] One connecting frame 212 connects the plurality of first clamping plates 2111 and the plurality of second clamping plates 2112 at the same time, resulting in a simple structure, high structural strength, and easy assembly operation.

[0139] In some embodiments of the present disclosure, one of the connecting frame 212 and the second clamping plate 2112 is provided with a first slide rail 2131 extending along the second direction, and the other is provided with a first slider 2132 slidably connected to the first slide rail 2131 .

[0140] The provision of the first slide rail 2131 and the first slider 2132 improves the smoothness of the movement of the second clamping plate 2112 .

[0141] In some embodiments of the present disclosure, the first slide rail 2131 is disposed on the connecting frame 212 , and the first slider 2132 is connected to the second clamping plate 2112 .

[0142] Such an arrangement improves the installation stability of the first slide rail 2131 , thereby improving the movement stability of the second clamping plate 2112 .

[0143] In some embodiments of the present disclosure, the paper tearing mechanism 2 further includes a moving mechanism 22 , which is disposed on the base 1 , and the clamp 21 is connected to the moving mechanism 22 , and the moving mechanism 22 is configured to drive the clamp 21 toward or away from the sheet 100 .

[0144] When paper tearing is required, the moving mechanism 22 drives the clamp 21 close to the sheet 100. When the clamp 21 approaches the set position, it clamps the release paper. Then the moving mechanism 22 drives the clamp 21 to move along the set direction, thereby driving the release paper to be torn off from the adhesive surface of the sheet 100.

[0145] In this way, the moving mechanism 22 is used to drive the clamp 21 to move, and the moving mechanism 22 cooperates with the clamp 21 to complete the paper tearing operation.

[0146] In some embodiments of the present disclosure, the moving mechanism 22 includes a multi-axis robot.

[0147] Multi-axis robots are multi-purpose manipulators capable of automatic control, reprogrammable operation, multiple degrees of freedom, and rectangular motion. They primarily operate by performing linear motion along the X, Y, and Z axes. Multi-axis robots include three-axis, four-axis, five-axis, and six-axis robots.

[0148] The multi-axis robot has the characteristics of repeatable programming, automatic control, multiple degrees of freedom, etc. The mobile fixture 21 has high precision, which improves the success rate of paper tearing.

[0149] In some embodiments of the present disclosure, the sheet 100 has a first adhesive surface and a second adhesive surface, both of which are covered with release paper, and the tearing mechanism 2 is used to tear off the release paper covering the first adhesive surface or the second adhesive surface.

[0150] The paper tearing device is used to tear off the release paper on the first side of the sheet 100.

[0151] It should be noted that the first adhesive surface and the second adhesive surface of the sheet 100 are both covered by release paper, that is, the sheet 100 is not adhered to other components. During the paper tearing operation, the sheet 100 needs to be positioned separately so that the paper tearing operation is completed when the paper tearing mechanism 2 is in action.

[0152] In some embodiments of the present disclosure, the sheet 100 has a first adhesive surface and a second adhesive surface, the release paper covers the second adhesive surface, and the tearing mechanism 2 is used to tear the sheet 100 adhered to the first adhesive component 200 through the first adhesive surface to tear off the release paper covering the second adhesive surface.

[0153] The paper tearing device is used to tear off the release paper on the second surface of the sheet material 100 adhered to the first adhesive component 200 .

[0154] It should be noted that the sheet 100 is adhered to the first adhesive component 200 through the first adhesive surface, that is, the sheet 100 is attached to the first adhesive component 200. During the paper tearing operation, positioning the first adhesive component 200 can indirectly limit the position of the sheet 100, thereby completing the paper tearing operation when the paper tearing mechanism 2 is activated.

[0155] In some embodiments of the present disclosure, as shown in Figure 6, the paper tearing device also includes a positioning mechanism 9 for positioning the first adhesive component 200, and the positioning mechanism 9 includes at least two positioning structures arranged in sequence along the first direction, and each positioning structure is used to limit the position of the first adhesive component 200 in a one-to-one correspondence.

[0156] The positioning mechanism 9 is used to position the at least two first adhesive-applying components 200, thereby defining the positions of the sheets 100 adhered to the at least two first adhesive-applying components 200, so that the at least two sheets 100 are spaced apart from each other along the first direction. In this way, the at least two clamping assemblies 211 of the clamp 21 can clamp the release paper of the at least two sheets 100 in a one-to-one correspondence. During the paper tearing operation, the positioned sheets 100 do not move with the clamp 21, thereby smoothly tearing the release paper from the sheets 100.

[0157] In some embodiments of the present disclosure, the positioning structure includes a bearing portion 91, a positioning block 92 and a pushing block 93. The bearing portion 91 defines a bearing area. The positioning block 92 and the pushing block 93 are respectively arranged on opposite sides of the bearing area along the first direction. The pushing block 93 is configured to be able to approach or move away from the corresponding positioning block 92 along the first direction to clamp or loosen the first adhesive component 200 located in the bearing area.

[0158] In this way, the positioning function of the positioning structure for the first adhesive component 200 is achieved. Moreover, the positioning structure has a simple structure and a simple assembly process.

[0159] In some embodiments of the present disclosure, the pushing blocks 93 of each positioning structure are simultaneously connected to the same connecting plate, and the connecting plate moves back and forth along the first direction under the drive of the third driving member.

[0160] In this way, the third driving member can drive at least two pushing blocks 93 to move back and forth in the first direction at the same time, simplifying the structure of the positioning mechanism 9 and saving costs, and can make at least two pushing blocks 93 move synchronously, optimizing the positioning effect of at least two first adhesive components 200.

[0161] In some embodiments of the present disclosure, the positioning mechanism 9 is arranged on one side of the first detection camera 3 and the second detection camera 4 along the second direction, and the second direction intersects the first direction, and the intersection includes a vertical intersection; the first bonding surface of the sheet 100 is bonded to the side of the first adhesive component 200 along the second direction where the first detection camera 3 and the second detection camera 4 are located.

[0162] In this way, the first detection camera 3 and the second detection camera 4 are set toward the second adhesive surface of the sheet 100 covered with the release paper, so that the first detection camera 3 and the second detection camera 4 can photograph the second adhesive surface of the sheet 100 located on the positioning mechanism 9 after the paper tearing action is completed, thereby detecting the release paper residue on the second adhesive surface.

[0163] In some embodiments of the present disclosure, the positioning mechanism 9 is transferred on the production line as a pallet. The previous process is a process of bonding the sheet 100 to the first adhesive component 200 positioned on the positioning mechanism 9 through the first adhesive surface. After the bonding process is completed, the positioning mechanism 9 is transferred to the side at a set distance from the first detection camera 3 and the second detection camera 4, so as to tear off the release paper covering the second adhesive surface.

[0164] In some embodiments of the present disclosure, the first adhesive component 200 includes a battery cell, and the sheet 100 includes a thermal insulation pad.

[0165] The disclosed embodiment can be applied to the process of pasting thermal insulation pads on battery cells. Since the first detection camera 3 and the second detection camera 4 can detect multiple thermal insulation pads at the same time, the release paper detection efficiency can be improved. When replacing a larger thermal insulation pad and performing a paper tearing operation on the larger thermal insulation pad, the distance between the first detection camera 3 and the second detection camera 4 can be increased, and the shooting field of view of the first detection camera 3 and the second detection camera 4 can be increased, so that at least two thermal insulation pads are located within the shooting field of view, thereby improving the compatibility of release paper detection without reducing the release paper detection efficiency. Moreover, when replacing a smaller thermal insulation pad and performing a paper tearing operation on the smaller thermal insulation pad, the distance between the first detection camera 3 and the second detection camera 4 can be reduced, and the shooting field of view of the first detection camera 3 and the second detection camera 4 can be reduced, and the overlapping shooting field of view of the first detection camera 3 and the second detection camera 4 can be increased. In this way, the thermal insulation pads located in the overlapping shooting fields of view are detected separately by the first detection camera 3 and the second detection camera 4, which is conducive to improving the detection accuracy.

[0166] FIG7 is a flow chart of a paper tearing method provided in some embodiments of the present disclosure.

[0167] As shown in FIG7 , a second aspect of the present disclosure provides a paper tearing method, wherein a paper tearing device is used to tear a sheet 100, wherein the sheet 100 has an adhesive surface covered with release paper. The paper tearing device includes a base 1, a paper tearing mechanism 2, a first detection camera 3, and a second detection camera 4. The paper tearing method includes:

[0168] S1, paper tearing action: the paper tearing mechanism tears off the release paper covering the adhesive surface of a plurality of sheets arranged sequentially along a first direction;

[0169] S2, detection preparation action: the first detection camera and / or the second detection camera moves a set distance so that each sheet is within the shooting field of view of the first detection camera and / or the second detection camera;

[0170] S3, detection action: the first detection camera and the second detection camera jointly photograph the multiple sheets that have completed the paper tearing action and detect whether the release paper is completely torn off based on the photographed images.

[0171] In this paper tearing method, the first detection camera 3 and the second detection camera 4 simultaneously detect multiple sheets 100, which can improve the efficiency of release paper detection. When replacing a larger sheet 100 and performing a paper tearing operation on the larger sheet 100, the distance between the first detection camera 3 and the second detection camera 4 can be increased, and the shooting field of view of the first detection camera 3 and the second detection camera 4 can be increased, so that at least two sheets 100 are located within the shooting field of view, thereby improving the compatibility of release paper detection without reducing the efficiency of release paper detection. Moreover, when replacing a smaller sheet 100 and performing a paper tearing operation on the smaller sheet 100, the distance between the first detection camera 3 and the second detection camera 4 can be reduced, and the shooting field of view of the first detection camera 3 and the second detection camera 4 can be reduced, and the overlapping shooting field of view of the first detection camera 3 and the second detection camera 4 can be increased. In this way, the sheets 100 located in the overlapping shooting fields of view are detected separately by the first detection camera 3 and the second detection camera 4, thereby helping to improve detection accuracy.

[0172] In some embodiments of the present disclosure, the sheet 100 has a first adhesive surface and a second adhesive surface, both of which are covered with release paper.

In step S1, the tearing mechanism 2 is used to tear the sheet 100 adhered to the first adhesive component 200 through the first adhesive surface to tear off the release paper covering the second adhesive surface.

[0175] The paper tearing method is used to tear off the release paper on the second surface of the sheet material 100 adhered to the first adhesive component 200 .

The gluing device includes a paper tearing device and a gluing device 1000, wherein the paper tearing device includes a base 1, a paper tearing mechanism 2, a first detection camera 3, and a second detection camera 4.
