[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure is based on the Chinese patent application with application number 202311423218.3, application date October 30, 2023, and invention name “Glue Laminating Method and Glue Laminating Equipment”, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into this disclosure as a reference. Technical Field

[0003] The present disclosure relates to the field of battery technology, and in particular to a glue laminating method and glue laminating equipment. 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] Currently, in the process of applying glue to battery cells, after the glue is applied to the battery cells, the appearance of the glue is inspected by the winding equipment to determine whether it is defective (NG). If it is determined to be defective, the defective glue is processed, which seriously affects the production efficiency of the battery cells. The intelligence of the related equipment used for gluing is poor.

[0006] Summary of the Invention

[0007] The embodiments of the present disclosure provide a glue laminating method and glue laminating equipment, which can effectively improve the intelligence of the glue laminating equipment, thereby improving the production efficiency of battery cells.

[0008] The technical solution of the embodiment of the present disclosure is implemented as follows:

[0009] In a first aspect, an embodiment of the present disclosure provides a method for processing glue application, which is applied to a control device in a glue application device, wherein the glue application device includes a detection device and a glue removal device, and the method includes:

[0010] When it is determined that the adhesive preparation is completed, obtaining a test result obtained by the testing device on the adhesive tape section to be applied;

[0011] When it is determined based on the detection result that the adhesive tape segment to be applied is a defective adhesive tape segment, the adhesive removal device is controlled to remove the adhesive tape segment to be applied.

[0012] In this embodiment, whenever the glue preparation is completed and a tape segment to be pasted is obtained, the control device in the glue pasting equipment can obtain the detection result obtained by the detection device in the glue pasting equipment for the tape segment to be pasted, so that it can be determined whether the tape segment to be pasted is a defective tape segment, that is, whether the tape segment to be pasted is NG based on the detection result, so that when it is determined that the pasted tape segment is a defective tape segment, the control device can control the glue removal device to remove the defective tape segment; that is, the glue pasting equipment in the present disclosure can perform quality inspection on the tape segment to be pasted before gluing the battery cell, including before gluing the tail glue on the battery cell, and before the tape segment to be pasted is pasted on the battery cell, so as to remove the defective tape segment in advance, which greatly improves the intelligence of the glue pasting equipment; thereby, the tape segments subsequently pasted on the battery cell can be all good tape segments, and there is no need to process the defective tail glue for the battery cell that has been glued, which can greatly improve the production efficiency of the battery cell.

[0013] In some embodiments of the present disclosure, the detection device includes a visual detection device, and obtaining a detection result obtained by the detection device on the tape segment to be applied includes:

[0014] Controlling the visual inspection device to collect the image to be inspected from the tape segment to be applied;

[0015] The quality of the tape segment in the image to be inspected is inspected to obtain an inspection result.

[0016] In this embodiment, the detection device can be a visual detection device, whereby the control device can control the visual detection device to collect an image corresponding to the tape segment to be pasted, obtain the image to be detected, and directly detect the image to be detected, thereby obtaining a detection result that can reflect the quality of the tape segment, thereby realizing effective detection of the quality of the tape segment to be pasted.

[0017] In some embodiments of the present disclosure, the tape segment to be applied carries label information indicating the quality of the tape segment to be applied;

[0018] Obtaining a test result obtained by the testing device on the tape segment to be applied, including:

[0019] The detection device is controlled to detect the label information on the adhesive tape section to be attached and obtain a detection result.

[0020] In this embodiment, by setting label information representing the quality of the tape segment to be pasted on the tape segment to be pasted, the control device can directly control the detection device to detect the label information on the tape segment to be pasted, and the detection result can be obtained, thereby realizing rapid detection of the quality of the tape segment to be pasted.

[0021] In some embodiments of the present disclosure, the detection device is a grating sensor, and the length of the label information includes a first length indicating that the tape segment to be applied is a good tape segment, and a second length indicating that the tape segment to be applied is a bad tape segment, wherein the shorter of the first length and the second length does not exceed the detection range of the grating sensor, and the longer of the first length and the second length exceeds the detection range of the grating sensor;

[0022] The control detection device detects the label information on the tape segment to be applied and obtains the detection results, including:

[0023] The grating sensor is controlled to detect the length of the label information to obtain the detection result.

[0024] In this embodiment, the detection device can also be a grating sensor, and two situations are set for the length of the label information, one is a first length that characterizes that the tape segment to be pasted is a good tape segment, and the other is a second length that characterizes that the tape segment to be pasted is a bad tape segment; and since the shorter of the first length and the second length does not exceed the detection range of the grating sensor, and the longer of the first length and the second length exceeds the detection range of the grating sensor, the control device can control the grating sensor to detect the length of the label information, and can determine whether the tape segment to be pasted is a good tape segment or a bad tape segment, thereby realizing rapid detection of the quality of the tape segment to be pasted and effectively improving the accuracy of detecting the quality of the tape segment to be pasted.

[0025] In some embodiments of the present disclosure, the first length is smaller than the second length; the first length does not exceed the detection range of the grating sensor, and the second length exceeds the detection range of the grating sensor.

[0026] In this embodiment, since the first length is smaller than the second length, and the first length does not exceed the detection range of the grating sensor, and the second length exceeds the detection range of the grating sensor, when the control device detects the length of the label information by controlling the grating sensor, by determining whether the label information can be detected, it can be determined whether the length of the label information on the tape segment to be pasted is the first length or the second length, thereby determining the quality of the tape segment to be pasted, and effectively improving the accuracy of detecting the quality of the tape segment to be pasted.

[0027] In some embodiments of the present disclosure, when the grating sensor includes a first grating sensor,

[0028] The label information is set at a first preset position of the tape segment to be attached. The first preset position is such that when the tape segment to be attached with the label information of the first length moves in the moving direction, it is not within the detection range of the first grating sensor, and when the tape segment to be attached with the label information of the second length moves in the moving direction, it is within the detection range of the first grating sensor.

[0029] The method also includes:

[0030] If the detection result is that the first grating sensor detects the label information, it is determined that the tape segment to be applied is a defective tape segment.

[0031] In this embodiment, the label information is set at a first preset position of the tape segment to be pasted, and the first preset position is a position where the tape segment to be pasted with label information of the first length is not within the detection range of the first grating sensor when the tape segment to be pasted moves in the moving direction, and is within the detection range of the first grating sensor when the tape segment to be pasted with label information of the second length moves in the moving direction; thus, when the grating sensor includes the first grating sensor, that is, only includes one grating sensor, the control device can only use this first grating sensor to detect the label information on the tape segment to be pasted to determine whether the label information can be detected, and thus when it is determined that the label information can be detected, it means that the length of the label information on the tape segment to be pasted is the second length. Since the second length is the length that characterizes that the tape segment to be pasted is a defective tape segment, it can be determined that the tape segment to be pasted is a defective tape segment, thereby achieving accurate detection of defective tape segments and effectively improving the intelligence of the gluing equipment.

[0032] In some embodiments of the present disclosure, when the detection device further includes a second grating sensor, and when the tape segment to be applied of the first length moves in a moving direction, and the label information is within the detection range of the second grating sensor, the method further includes:

[0033] If the detection result is that the second grating sensor detects the label information and the first grating sensor does not detect the label information, it is determined that the tape segment to be applied is a good tape segment;

[0034] If the detection result is that both the first grating sensor and the second grating sensor detect the label information, it is determined that the tape segment to be applied is a defective tape segment;

[0035] If the detection result is that neither the first photoelectric grating sensor nor the second photoelectric grating sensor detects the label information, it is determined that the tape segment to be applied is a defective tape segment.

[0036] In this embodiment, the detection device may also include a first grating sensor and a second grating sensor at the same time, so that the control device can determine whether the tape segment to be pasted is a good product based on the detection conditions of the first grating sensor and the second grating sensor; further, since the label information of the tape segment to be pasted of the first length is within the detection range of the second grating sensor when the tape segment to be pasted moves in the moving direction; therefore, when the first grating sensor and the second grating sensor are used to detect the label information on the tape segment to be pasted when the tape segment moves in the moving direction, if the second grating sensor can detect the label information, the first grating sensor If the sensor does not detect the label information, it means that the length of the label information is the first length, and the tape segment to be pasted can be determined to be a good tape segment; if both the first grating sensor and the second grating sensor can detect the label information, it means that the length of the label information is the second length, and the tape segment to be pasted can be determined to be a bad tape segment; if both the first grating sensor and the second grating sensor cannot detect the label information, it means that the tape segment to be pasted does not carry label information, and it can also be determined that the tape segment to be pasted is a bad tape segment; thereby achieving accurate detection of the quality of the tape segment to be pasted and improving the intelligence of the gluing equipment.

[0037] In some embodiments of the present disclosure, the gluing device further includes a gluing roller and a first driving device, wherein the gluing roller is used to absorb the tape segment to be applied; and the method further includes:

[0038] If the tape segment to be applied is determined to be a defective tape segment according to the detection result, a first drive instruction is sent to the first drive device, so that the first drive device drives the glue application roller to move until the positioning angle of the glue application roller meets the first glue removal angle; wherein the first glue removal angle represents the angle of docking with the glue removal device.

[0039] In this embodiment, when it is determined that the tape segment to be pasted is a defective tape segment, the gluing equipment can perform glue removal. At this time, the control device can send a first drive instruction to the first drive device in the gluing equipment, so that the first drive device drives the gluing roller to move to the positioning angle of the gluing roller that meets the angle of docking with the glue removal device, thereby preparing for subsequent glue removal to achieve precise glue removal.

[0040] In some embodiments of the present disclosure, the glue removal device includes a cylinder and a glue removal roller; and the method further includes:

[0041] When it is determined that the positioning angle of the glue roller moved to the glue roller meets the first glue removal angle, and the cylinder drives the glue removal roller to extend to the glue removal position, the glue roller is controlled to be vacuum closed so that the tape segment to be applied is attached to the glue removal roller; wherein the glue removal position represents the position of contact with the glue roller.

[0042] In this embodiment, when it is determined that the glue roller and the glue removal roller have moved to a position where the removal process can be performed, that is, when the glue roller moves to a positioning angle that meets the first glue removal angle, and the glue removal roller is extended to the glue removal position, the control device can control the glue roller to perform vacuum closure, so that the tape segment to be applied attached to the glue roller is no longer attached to the glue roller, but attached to the glue removal roller, thereby realizing the automatic removal of defective tape segments and greatly improving the intelligence of the glue equipment.

[0043] In some embodiments of the present disclosure, after controlling the adhesive roller to close the vacuum so that the tape segment to be applied is attached to the adhesive removal roller, the method further includes:

[0044] Control the glue roller to perform vacuum treatment;

[0045] If the vacuuming signal corresponding to the adhesive roller is not received, it is determined that the tape segment to be applied has been removed and the removal process is completed;

[0046] If a vacuum pumping signal corresponding to the glue roller is received, it is determined that the tape segment to be applied has not been removed, and an alarm signal is generated; wherein the vacuum pumping signal is used to determine that the glue roller has performed the vacuum pumping process.

[0047] In this embodiment, after controlling the glue roller to perform vacuum closure so that the tape segment to be applied is attached to the glue removal roller, it is also possible to confirm whether the tape segment to be applied has been removed; specifically, the control device mainly controls the glue roller to perform vacuum processing again to determine whether the vacuum signal can be received. If the vacuum signal is not received, it means that the tape segment attached thereto has been removed, so that the glue roller cannot be vacuumed at this time; and if the vacuum signal is received, it means that the tape segment on it is still in an attached state and has not been removed, so vacuuming can be performed, and then an alarm signal can be generated to prompt that processing is required, thereby realizing the inspection of whether the tape segment to be removed has been successfully removed. Even if the tape segment to be removed is not removed, a prompt can be given, which greatly improves the reliability of the glue application equipment when performing the removal process and effectively improves the intelligence of the glue application equipment.

[0048] In a second aspect, an embodiment of the present disclosure provides a glue laminating device, the glue laminating device including a detection device, a glue removing device, and a control device;

[0049] The control device is connected to the detection device and the glue removing device respectively;

[0050] A detection device is used to detect the tape section to be applied after the adhesive preparation is completed;

[0051] Glue removal device, used to remove defective tape segments;

[0052] The control device is used to control the adhesive removal device to remove the tape segment to be applied when the tape segment to be applied is determined to be a defective tape segment based on the detection result obtained by the detection device. BRIEF DESCRIPTION OF THE DRAWINGS

This can effectively improve the intelligence of the glue application equipment, thereby improving the production efficiency of the battery cells.

[0068] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present disclosure.

[0069] An embodiment of the present disclosure provides a glue laminating method, which is applied to a control device in a glue laminating device.

[0070] FIG1 is a schematic diagram of the structure of the adhesive laminating device according to an embodiment of the present disclosure. As shown in FIG1 , the adhesive laminating device 0 may include a control device 1, a detection device 2, and a adhesive removal device 3. The control device 1 may be connected to the detection device 2 and the adhesive removal device 3, respectively; wherein:

[0071] The control device 1 can be a programmable logic controller (PLC) in the glue application device 0; the control device 1 can be used to obtain the detection result obtained by the detection device on the tape segment to be applied when it is determined that the glue preparation is completed; and when it is determined based on the detection result that the tape segment to be applied is a defective tape segment, the glue removal device can be controlled to remove the tape segment to be applied. The detection device 2 can be used to detect the quality of the tape segment to be applied obtained after the glue preparation process, wherein, after the glue preparation process, the tape segment to be applied will pass through the detection range of the detection device 2. The glue removal device 3 can be used to remove the defective tape segment.

[0072] In an embodiment of the present disclosure, FIG2 is a schematic diagram of a first implementation flow of the method for gluing processing proposed in an embodiment of the present disclosure. As shown in FIG2 , in an embodiment of the present disclosure, the method for performing the gluing processing by the control device in the gluing device may include the following steps:

[0073] Step 101: When it is determined that adhesive preparation is completed, a detection result obtained by a detection device on the adhesive tape segment to be applied is obtained.

[0074] In an embodiment of the present disclosure, the control device may first obtain a detection result obtained by the detection device on the tape segment to be applied when determining that the adhesive preparation is completed.

[0075] It should be noted that in the embodiments of the present disclosure, each time the glue is prepared, a corresponding tape segment will be obtained, and the tape segment can be a tape segment to be pasted on the battery cell; for example, the tape segment to be pasted can be a section of tail glue, and the tail glue obtained after the glue preparation process is pasted on the battery cell, which can play a role of isolation and protection.

[0076] In an embodiment of the present disclosure, the detection device may be used to detect the quality of the adhesive tape segment to be applied, so as to determine whether the adhesive tape segment to be applied is good quality adhesive.

[0077] In some embodiments of the present disclosure, the detection device may include a visual detection device; when the control device obtains the detection result obtained by the detection device on the tape segment to be applied, it can control the visual detection device to capture an image of the tape segment to be applied; and detect the quality of the tape segment in the image to be detected to obtain the detection result.

[0078] It should be noted that, in the embodiments of the present disclosure, the visual detection device may be any device that can be used to collect image information, and the present disclosure does not make any specific limitation.

[0079] It can be understood that in the embodiment of the present disclosure, the visual inspection device can collect image information corresponding to the tape segment to be pasted, that is, obtain the image to be detected, so that the control device can determine whether the tape segment to be pasted is a good quality adhesive based on the image to be detected after obtaining the image to be detected collected by the visual inspection device.

[0080] It should be noted that, in the embodiments of the present disclosure, the present disclosure does not limit the specific detection method for detecting the quality of the tape segment in the image to be detected or the specific detection content of the image to be detected for determining the detection result.

[0081] Exemplarily, the visual inspection device is a camera system, and the section of tape to be pasted is a section of tail glue; after the control device collects the image to be inspected corresponding to this section of tail glue by controlling the camera system, the control device can directly inspect or identify the quality of the tail glue based on the image to be inspected to determine whether this section of tail glue has been printed with identification information, such as a QR code, etc.; and / or whether the identification information is printed clearly; and / or whether this section of tail glue has wrinkles, etc.; so when it is determined that there is no identification information on this section of tail glue; and / or the printing is unclear; and / or this section of tail glue has wrinkles, the inspection result is a defective product, that is, this section of tail glue is a defective tail glue; and when it is determined that there is identification information on this section of tail glue, and the identification information is printed clearly, and the tail glue has no wrinkles, the inspection result is determined to be a good product, that is, this section of tail glue is a good tail glue.

[0082] For example, the control device may detect the quality of the tape segment based on computer-aided design (CAD) technology to obtain a detection result.

[0083] In some embodiments of the present disclosure, the tape segment to be attached carries label information representing the quality of the tape segment to be attached; when the control device obtains the detection result obtained by the detection device on the tape segment to be attached, it can control the detection device to detect the label information on the tape segment to be attached to obtain the detection result.

[0084] Exemplarily, when the detection device is a visual detection device, the control device can control the visual detection device to detect the label information on the tape segment to be pasted, thereby obtaining a detection result based on the quality of the tape segment to be pasted represented by the label information, and determining whether the tape segment to be pasted is a good quality tape.

[0085] That is to say, in the embodiments of the present disclosure, not only can the quality of the tape segment be directly detected by the detection device to obtain the detection result; but also, in the case where the tape segment carries label information representing the quality of the tape segment to be attached, the detection device can be used to detect the label information on the tape segment to be attached to obtain the detection result.

[0086] In some embodiments of the present disclosure, the detection device may also be a grating sensor.

[0087] It should be noted that in the embodiment of the present disclosure, when the tape segment carries label information representing the quality of the tape segment to be pasted, in addition to using a visual inspection device to detect the label information on the tape segment to be pasted, a grating sensor can also be used to detect the label information on the tape segment to be pasted.

[0088] In some embodiments of the present disclosure, the length of the label information includes a first length that characterizes that the tape segment to be attached is a good tape segment, and a second length that characterizes that the tape segment to be attached is a bad tape segment, wherein the shorter of the first length and the second length does not exceed the detection range of the grating sensor, and the longer of the first length and the second length exceeds the detection range of the grating sensor.

[0089] In some embodiments of the present disclosure, when the control device controls the detection device to detect the label information on the tape segment to be attached and obtains the detection result, the control device can control the grating sensor to detect the length of the label information and obtain the detection result.

[0090] It should be noted that, in the embodiments of the present disclosure, the grating sensor can be used to detect whether there is label information within the corresponding detection range; since the lengths of the label information corresponding to the defective tape segment and the good tape segment are different, it is possible that when the grating sensor detects label information of different lengths, there may be label information or no label information, thereby determining whether the label information is used to characterize the good tape segment or the label information is used to characterize the defective tape segment.

[0091] In some embodiments of the present disclosure, the first length is smaller than the second length; the first length does not exceed the detection range of the grating sensor, and the second length exceeds the detection range of the grating sensor.

[0092] In some embodiments of the present disclosure, the optical grating sensor may include a first optical grating sensor.

[0093] In some embodiments of the present disclosure, label information can be set at a first preset position of the tape segment to be affixed. The first preset position is that when the tape segment to be affixed with label information of a first length moves in the moving direction, it is not within the detection range of the first grating sensor, and when the tape segment to be affixed with label information of a second length moves in the moving direction, it is within the detection range of the first grating sensor.

[0094] In some embodiments of the present disclosure, if the detection result is that the first grating sensor detects label information, the tape segment to be attached is determined to be a defective tape segment; if the detection result is that the first grating sensor does not detect label information, the tape segment to be attached is determined to be a good tape segment.

[0095] It should be noted that in the embodiments of the present disclosure, the tape segment to be pasted obtained after preparation of the glue will move in a certain moving direction, thereby gradually approaching the detection range of the grating sensor or the visual detection device to complete the quality detection of the tape segment to be pasted; wherein, the moving direction of the tape segment when moving is not limited by the present disclosure.

[0096] For example, FIG3 is a schematic diagram of the position relationship of the grating sensors proposed in an embodiment of the present disclosure. As shown in FIG3 , from a top view perspective, the first grating sensor 21 is located directly above the tape segment 100 to be attached, and the first preset position of the tape segment 100 to be attached carries label information 25 of a first length; when the tape segment 100 to be attached moves in a moving direction, such as to the left, the label information 25 of the first length will not be within the detection range of the first grating sensor 21. Therefore, when the detection result is that the first grating sensor 21 does not detect the label information, it can be determined that the tape segment 100 to be attached is a good tape segment.

[0097] Exemplarily, Figure 4 is a second schematic diagram of the position relationship of the grating sensors proposed in an embodiment of the present disclosure. As shown in Figure 4, from the perspective of a top view, the first grating sensor 21 is located directly above the tape segment to be pasted, and the first preset position of the tape segment to be pasted carries label information 26 of the second length; when the tape segment 100 to be pasted moves in a moving direction, such as to the left, the label information 26 of the second length can be within the detection range of the first grating sensor 21, so that when the detection result is that the first grating sensor 21 detects the label information, it can be determined that the tape segment 100 to be pasted is a defective tape segment.

[0098] In some embodiments of the present disclosure, the detection device may further include a second grating sensor.

[0099] That is to say, in the embodiment of the present disclosure, in addition to using the first grating sensor to detect the label information on the tape segment to be attached, the first grating sensor and the second grating sensor can also be used simultaneously to detect the label information on the tape segment to be attached to obtain the detection result.

[0100] In some embodiments of the present disclosure, when a tape segment to be pasted with label information of a first length moves in a moving direction, and the label information is within the detection range of the second grating sensor, if the detection result is that the second grating sensor detects the label information and the first grating sensor does not detect the label information, then the tape segment to be pasted is determined to be a good tape segment; if the detection result is that both the first grating sensor and the second grating sensor detect the label information, then the tape segment to be pasted is determined to be a defective tape segment; if the detection result is that neither the first grating sensor nor the second grating sensor detects the label information, then the tape segment to be pasted is determined to be a defective tape segment.

[0101] Exemplarily, FIG5 is a third schematic diagram of the position relationship of the grating sensors proposed in an embodiment of the present disclosure. As shown in FIG5 , from the perspective of a top view, the first grating sensor 21 and the second grating sensor 22 are located above the tape segment 100 to be pasted, and can be used to detect the label information on the tape segment to be pasted below; assuming that the label information at the first preset position on the tape segment to be pasted is a first length, when the tape segment to be pasted moves to the left, the label information 25 of the first length will pass through the detection range of the second grating sensor 22, but cannot pass through the detection range of the first grating sensor 21. At this time, the detection result is that the second grating sensor 22 detects the label information, and the first grating sensor 21 does not detect the label information, so that the tape segment to be pasted can be determined. is a good tape segment; assuming that the label information on the tape segment to be pasted is the second length, when the tape segment to be pasted moves to the left, the label information 26 of the second length will pass through the detection range of the first grating sensor 21 and the second grating sensor 22 at the same time. At this time, the detection result is that both the first grating sensor 21 and the second grating sensor 22 detect the label information, so it can be determined that the tape segment to be pasted is a bad tape segment; and assuming that there is no label information on the tape segment to be pasted, it may be that the tape segment to be pasted has not undergone the quality inspection process or has passed the quality inspection process but the label information has been omitted, which will cause both the first grating sensor 21 and the second grating sensor 22 to fail to detect the label information, and it can also be determined that the tape segment to be pasted is a bad tape segment.

[0102] In some embodiments of the present disclosure, there may be a situation where the first grating sensor does not detect the label information, while the second grating sensor detects the label information. This situation may be caused by the fact that the label information of the first length is not set at the first preset position, but it can still be determined that the tape segment to be attached is a good tape segment.

[0103] Exemplarily, when the tape segment to be pasted moves in the moving direction, the first preset position is a position on the tape segment to be pasted close to the second grating sensor, for example, the first preset position is a position that will pass through the detection range of the second grating sensor; but the label information is not set at the first preset position, but is set at a position in the opposite direction of the first preset position, for example, a position close to the first grating sensor, which will pass through the detection range of the first grating sensor but not the detection range of the first grating sensor; in this case, when the label information on the tape segment to be pasted is detected based on the first grating sensor and the second grating sensor, the detection result will be that the first grating sensor does not detect the label information, and the second grating sensor detects the label information, and it can also be determined that the tape segment to be pasted is a good tape segment.

[0104] Step 102 : When it is determined based on the detection result that the adhesive tape segment to be applied is a defective adhesive tape segment, the adhesive removal device is controlled to remove the adhesive tape segment to be applied.

[0105] In an embodiment of the present disclosure, after determining that the glue preparation is completed, the control device obtains the detection result obtained by the detection device on the tape segment to be pasted, and can control the glue removal device to remove the tape segment to be pasted if it is determined that the tape segment to be pasted is a defective tape segment based on the detection result.

[0106] It should be noted that, in the embodiment of the present disclosure, Figure 6 is a schematic diagram of the composition structure of the glue removal device proposed in the embodiment of the present disclosure. As shown in Figure 6, the glue removal device may include a glue removal roller 31 and a cylinder 32, and the glue removal roller 31 and the cylinder 32 may be connected by a connecting device.

[0107] In some embodiments of the present disclosure, FIG7 is a second structural diagram of the gluing device proposed in the embodiments of the present disclosure. As shown in FIG7 , the gluing device 0 may further include a gluing roller 4 and a first driving device 5 .

[0108] It should be noted that, in the embodiment of the present disclosure, the glue-applying roller is used to absorb the tape segment to be applied; and the first driving device is used to drive the glue-applying roller.

[0109] In some embodiments of the present disclosure, if the control device determines that the tape segment to be applied is a defective tape segment based on the detection results, a first drive instruction is sent to the first drive device so that the first drive device drives the glue roller to move to a positioning angle of the glue roller that meets the first glue removal angle; wherein the first glue removal angle represents the angle of docking with the glue removal device.

[0110] In some embodiments of the present disclosure, the control device can control the glue roller to perform vacuum closure when it is determined that the positioning angle of the glue roller moves to a first glue removal angle, and the cylinder drives the glue removal roller to extend to the glue removal position, so that the tape segment to be applied is attached to the glue removal roller; wherein the glue removal position represents the position of contact with the glue roller.

[0111] It should be noted that, in the embodiment of the present disclosure, small holes are provided on the surface of the glue roller for absorbing the tape segment to be applied, and the side of the tape segment to be applied that contacts the surface of the glue roller is the non-sticky side, and the sticky side faces outward and does not contact the surface of the glue roller; when the vacuum of the glue roller is closed, the tape segment to be applied attached to the small holes on the surface of the glue roller will fall off, and at this time the glue removal roller is used to contact the sticky side of the tape segment to be applied to complete the glue removal.

[0112] In some embodiments of the present disclosure, after controlling the glue roller to perform vacuum closure so that the tape segment to be applied is attached to the glue removal roller, the control device can also control the glue roller to perform vacuum treatment; if the vacuum signal corresponding to the glue roller is not received, it is determined that the tape segment to be applied has been removed and the removal process is completed; if the vacuum signal corresponding to the glue roller is received, it is determined that the tape segment to be applied has not been removed, and an alarm signal is generated; wherein, the vacuum signal is used to determine that the glue roller has performed the vacuum treatment.

[0113] That is to say, in the embodiment of the present disclosure, when performing the rejection process, each time the tape segment to be attached to the adhesive removal roller is attached, a vacuum process is performed again to determine whether the tape segment to be attached has been removed, thereby improving the reliability of the rejection process.

[0114] It can be understood that in the embodiment of the present disclosure, since the glue-applying roller has a small hole, if the tape segment to be applied has been removed, the glue-applying roller cannot complete vacuuming due to the exposure of the small hole, that is, the control device cannot receive the vacuuming signal, thereby determining that the tape segment to be applied has been removed; and if the tape segment to be applied has not been removed, since the small hole is covered by the tape segment to be applied and is not exposed, vacuuming can be performed, and the control device can receive the vacuuming signal, thereby determining that the tape segment to be applied has not been removed.

[0115] In some embodiments of the present disclosure, the alarm signal may be used to indicate that the tape segment to be applied has not been removed, and manual intervention is required to remove the defective tape segment.

[0116] In an embodiment of the present disclosure, the gluing equipment includes a detection device and a glue removal device; the control device in the gluing equipment can obtain the detection result obtained by the detection device on the tape segment to be applied when it is determined that the glue preparation is completed; when it is determined based on the detection result that the tape segment to be applied is a defective tape segment, the glue removal device is controlled to remove the tape segment to be applied. Thus, it can be seen that whenever the glue preparation is completed and a tape segment to be pasted is obtained, the control device in the glue pasting equipment can obtain the detection result obtained by the detection device in the glue pasting equipment for the tape segment to be pasted, so that it can be determined whether the tape segment to be pasted is a defective tape segment based on the detection result, that is, whether the tape segment to be pasted is NG, so that when it is determined that the pasted tape segment is a defective tape segment, the control device can control the glue removal device to remove the defective tape segment; that is, the glue pasting equipment in the present disclosure can perform quality inspection on the tape segment to be pasted before gluing the battery cell, including before gluing the tail glue on the battery cell, and before the tape segment to be pasted is pasted on the battery cell, so as to remove the defective tape segment in advance, which greatly improves the intelligence of the glue pasting equipment; thereby, the tape segments subsequently pasted on the battery cell can be all good tape segments, and there is no need to process the defective tail glue for the battery cell that has been glued, which can greatly improve the production efficiency of the battery cell.

[0117] Based on the above embodiment, in another embodiment of the present disclosure, a glue sticking processing method is used to detect and process defective tail glue, that is, the tape segment to be pasted is a tail glue, which can be pasted on the bare battery cell to fix, isolate and protect the battery cell.

[0118] Exemplarily, the detection device adopts a first grating sensor and a second grating sensor. In combination with Figures 5 and 8, it can be seen that in the main view perspective of Figure 8, the first grating sensor 21 and the second grating sensor 22 are arranged on the supporting device 23, and the tail glue is in a planar position below the first grating sensor 21 and the second grating sensor 22, that is, the tail glue will pass through the plane 24 below the first grating sensor 21 and the second grating sensor 22; for the perspective of the top view, as shown in Figure 5, the first grating sensor 21 and the second grating sensor 22 are located above the tape segment to be pasted, and can be used to detect the label information on the tape segment to be pasted that moves below in the moving direction.

[0119] 5 and 8 , FIG9 is a second schematic diagram of the implementation process of the glue processing method proposed in the embodiment of the present disclosure. As shown in FIG9 , after executing glue preparation (step 201), the control device first determines whether the glue preparation is completed (step 202). If the glue preparation is completed, it determines whether the detection result of the detection device is that the second grating sensor detects the label information and the first grating sensor does not detect the label information (step 203); if the glue preparation is not completed, the glue preparation is continued; after step 203, if the judgment result is yes, wait for glue application (step 204); if the judgment result is no, perform the removal process (step 205), and determine whether the glue removal is completed (step 206); if completed, continue to enter the glue preparation process and start preparing the next tail glue to be applied. If the glue removal is not completed, an alarm message can be generated to request manual intervention to remove the defective tail glue.

[0120] In some embodiments of the present disclosure, Figure 10 is a third schematic diagram of the composition structure of the gluing equipment proposed in the embodiments of the present disclosure. As shown in Figure 10, the gluing equipment may include a gluing roller 4 and a glue removing device 3, wherein the glue removing device 3 is a newly added device on the original gluing equipment, which is used to remove defective tail glue.

[0121] In some embodiments of the present disclosure, when it is determined that the adhesive tail to be applied is defective, a adhesive removal device is required to remove the defective adhesive tail.

[0122] FIG11 is a third schematic diagram of the implementation process of the adhesive laminating method proposed in an embodiment of the present disclosure. As shown in FIG11 , the adhesive laminating method includes:

[0123] When the rejection process begins, the control device can control the glue swing arm to move the entire glue device to the second glue rejection angle, and move the glue roller to the first glue rejection angle (step 301); wherein, the second glue rejection angle represents an angle that can be used to perform the rejection process; when the control device moves the glue roller to the first glue rejection angle, it can send a first drive instruction to the first drive device, so that the first drive device drives the glue roller to move to the positioning angle of the glue roller that meets the first glue rejection angle; then it is determined whether the movement is completed (step 302), if so, the cylinder in the glue rejection device is controlled to extend (step 303); then it is determined whether the cylinder is extended to the position (step 304), if the cylinder is extended to the position, the glue roller vacuum can be controlled to be closed (step 305), and it is determined whether the glue roller is vacuum Close (step 306). If so, the glue removal roller can be controlled by the cylinder to move and rotate to the glue removal position (step 307). Then, it is determined whether the glue removal roller is in place (step 308). If so, the glue roller is controlled to be vacuumed again (step 309) to execute the confirmation process of whether the bad tail glue has been removed. After step 309, it is determined whether there is a vacuuming signal (step 310). If not, it is determined that the bad tail glue has been removed and the glue removal is completed (step 311). If there is a vacuuming signal, an alarm signal is generated (step 312) to request manual intervention to remove the bad tail glue. In addition, after step 308, if it is determined that the glue removal roller is not in place, step 312 can also be executed to generate an alarm signal to request manual intervention to adjust or handle the situation.

[0124] In an embodiment of the present disclosure, the gluing equipment includes a detection device and a glue removal device; the control device in the gluing equipment can obtain the detection result obtained by the detection device on the tape segment to be applied when it is determined that the glue preparation is completed; when it is determined based on the detection result that the tape segment to be applied is a defective tape segment, the glue removal device is controlled to remove the tape segment to be applied. Thus, it can be seen that whenever the glue preparation is completed and a tape segment to be pasted is obtained, the control device in the glue pasting equipment can obtain the detection result obtained by the detection device in the glue pasting equipment for the tape segment to be pasted, so that it can be determined whether the tape segment to be pasted is a defective tape segment based on the detection result, that is, whether the tape segment to be pasted is NG, so that when it is determined that the pasted tape segment is a defective tape segment, the control device can control the glue removal device to remove the defective tape segment; that is, the glue pasting equipment in the present disclosure can perform quality inspection on the tape segment to be pasted before gluing the battery cell, including before gluing the tail glue on the battery cell, and before the tape segment to be pasted is pasted on the battery cell, so as to remove the defective tape segment in advance, which greatly improves the intelligence of the glue pasting equipment; thereby, the tape segments subsequently pasted on the battery cell can be all good tape segments, and there is no need to process the defective tail glue for the battery cell that has been glued, which can greatly improve the production efficiency of the battery cell.
