Battery gluing equipment and battery gluing method Technical Field

[0001] The present application relates to the field of batteries, and in particular to a battery gluing device and a battery gluing method. Background Art

[0002] During the battery production process, batteries undergo a gluing process. After gluing, the results must be inspected and unqualified batteries promptly removed. While removing unqualified batteries at the gluing inspection station, the operator must wait for the robot to remove them, disrupting the inspection process and affecting production schedules.

[0003] Summary of the Invention

[0004] In view of the above problems, an embodiment of the present application provides a battery gluing device that can detect and discharge unqualified batteries without affecting the normal progress of the previous process and without occupying the production cycle.

[0005] An embodiment of the present application provides a battery gluing device, including: a gluing detection mechanism for detecting the gluing results of batteries; a defective product receiving mechanism for receiving batteries with unqualified gluing detected by the gluing detection mechanism; a transfer mechanism for transferring unqualified batteries detected by the gluing detection mechanism to the defective product receiving mechanism; and a conveyor line for transferring batteries from the gluing detection mechanism to the transfer mechanism.

[0006] The battery gluing equipment provided in the embodiment of the present application is configured so that the transfer mechanism for discharging unqualified batteries is arranged at a downstream station of the station where the gluing detection mechanism is located on the conveyor line, so that the detection operation of the gluing detection mechanism and the transfer operation of the transfer mechanism for transferring unqualified batteries are performed at different stations of the battery conveyor line, so that the transfer operation of unqualified batteries will not affect the detection operation of the gluing detection mechanism and will not affect the production rhythm.

[0007] In some embodiments, the defective product receiving mechanism includes a discharge line arranged at an angle relative to the conveyor line, and the unqualified batteries are transferred to the discharge line via a transfer mechanism. Using the discharge line arranged at an angle relative to the conveyor line, batteries that fail the adhesive bonding test are discharged via the transfer mechanism and the discharge line.

[0008] In some embodiments, the conveyor line has a preset length between the adhesive testing mechanism and the transfer mechanism to accommodate batteries that have been inspected by the adhesive testing mechanism. The conveyor line has a preset length between the adhesive testing mechanism and the defective product discharge mechanism. When the transfer mechanism takes longer to transfer defective batteries than the adhesive testing mechanism, batteries that have been inspected at the adhesive testing station can be accommodated within the preset length, thereby not occupying the inspection station and not affecting the production cycle.

[0009] In some embodiments, the glue detection mechanism is arranged on a first frame of the conveyor line, and the transfer mechanism is arranged on a second frame of the conveyor line. The first frame and the second frame provide stable support for the glue detection mechanism and the transfer mechanism.

[0010] In some embodiments, the adhesive application detection mechanism includes: a first frame disposed across the conveyor line; a first longitudinal guide rail disposed on the first frame and parallel to the conveyor line; and a vision system disposed on and movable along the first longitudinal guide rail, the vision system being configured to detect batteries on the conveyor line. This structural arrangement of the adhesive application detection mechanism allows the vision system of the adhesive application detection mechanism to be securely supported across the conveyor line and movable along the longitudinal guide rail parallel to the conveyor line.

[0011] In some embodiments, the battery gluing equipment includes at least two parallel conveyor lines, and the visual system of the gluing inspection mechanism is correspondingly provided with a visual camera for each conveyor line. By providing a visual camera for each conveyor line, it is possible to ensure that the batteries on each conveyor line are inspected.

[0012] In some embodiments, the transfer mechanism includes a battery grabbing member and a second frame. The battery grabbing member can move on the second frame in directions parallel to and perpendicular to the conveyor line, and can also move in a vertical direction, so that the battery grabbing member can be aligned with the unqualified glued batteries on the conveyor line and aligned with the defective product receiving mechanism. The configuration of the second frame of the transfer mechanism enables the battery grabbing member to move in three directions, namely, in a direction parallel to the conveyor line, a direction perpendicular to the conveyor line, and a vertical direction, so that the battery grabbing member can grab the defective batteries and transfer them to the defective product receiving mechanism.

[0013] In some embodiments, the second frame includes: at least one transverse guide rail disposed across the conveyor line; a second longitudinal guide rail extending parallel to the conveyor line and capable of moving on the transverse guide rail; and at least one vertical guide rail disposed on the second longitudinal guide rail and capable of moving along the second longitudinal guide rail, wherein the battery grabbing member is disposed on the vertical guide rail and capable of moving in a vertical direction along the vertical guide rail. The arrangement of the transverse guide rail, the longitudinal guide rail, and the vertical guide rail of the second frame of the transfer mechanism enables the second frame to guide the battery grabbing member to move in a direction parallel to the conveyor line, a direction perpendicular to the conveyor line, and a vertical direction.

[0014] In some embodiments, the second frame includes two transverse guide rails, and both ends of the second longitudinal guide rail are supported on the transverse guide rails respectively. The arrangement of the two transverse guide rails of the second frame provides a stable support for the longitudinal guide rail.

[0015] In some embodiments, the battery gripping member is configured as a manipulator, and the transfer mechanism includes a number of manipulators that matches the number of cells in each battery pack being transferred on the conveyor line. The number of manipulators in the battery gripping member is configured to match the number of cells in each battery pack being transferred on the conveyor line, enabling a plurality of batteries to be transferred from the conveyor line at once.

[0016] In some embodiments, the transfer mechanism includes a plurality of manipulators, each manipulator being disposed on a vertical guide rail, the vertical guide rails being disposed side by side with the second longitudinal guide rail, wherein at least one vertical guide rail is movable along the second longitudinal guide rail. The vertical guide rails disposed side by side enable the transfer mechanism to be provided with a plurality of manipulators side by side.

[0017] An embodiment of the present application provides a battery gluing method, which includes: using a gluing detection mechanism to detect the gluing results of the battery; associating the unqualified detection results with the identification information of the battery with unqualified gluing; using a conveyor line to transmit the detected battery to a transfer mechanism; identifying the identification information of the battery on the conveyor line to determine whether there is a battery with unqualified gluing; if so, using the transfer mechanism to transfer the unqualified battery on the conveyor line to a defective product receiving mechanism.

[0018] The battery gluing method provided in this embodiment enables the operation of the transfer mechanism for discharging unqualified batteries to be performed at a downstream station of the station where the gluing detection mechanism is located on the conveyor line, so that the detection operation of the gluing detection mechanism and the operation of the transfer mechanism for transferring unqualified batteries are performed at two different stations of the battery conveyor line, so that the transfer operation of unqualified batteries will not affect the detection operation of the gluing detection mechanism and will not affect the production rhythm.

[0019] In some embodiments, using a glue testing mechanism to test the glue application results of a battery includes: using the glue testing mechanism to collect dimensional information of the glue strip and dimensional information of the battery, and determining whether to generate an unqualified test result based on a comparison of the collected dimensional information of the glue strip and the collected dimensional information of the battery. By collecting and comparing the dimensional information of the glue strip and the dimensional information of the battery, it can be determined whether the glue application is unqualified.

[0020] In some embodiments, using a glue detection mechanism to collect dimensional information of the adhesive strip and the battery includes: capturing an image of the battery carrying the adhesive strip; determining the positions of the four sides of the battery and the edges of the adhesive strip based on image recognition; and determining whether to generate an unqualified detection result based on a comparison of the collected dimensional information of the adhesive strip with the collected dimensional information of the battery includes: calculating the distance from the edge of each adhesive strip to a corresponding edge of the four sides of the battery; and generating an unqualified detection result if the distance from the edge of any adhesive strip to the corresponding edge of the battery does not meet a predetermined tolerance range. By capturing image information of the battery and the adhesive strip and recognizing the image information, the positions of the edges of the battery and the adhesive strip can be determined, thereby obtaining dimensional information. By calculating the distance from the edge of the adhesive strip to a corresponding edge of the four sides of the battery, it can be determined whether each distance meets a predetermined tolerance range, thereby generating an unqualified detection result.

[0021] In some embodiments, determining the positions of the four sides of the battery and the edges of the adhesive strip based on image recognition includes: obtaining grayscale information of two intersecting edges of the battery in the image, establishing a coordinate system with the intersection of the two intersecting edges of the battery in the image as the origin; obtaining grayscale information of the four sides of the battery in the image, and determining the positions of the four sides of the battery in the image in the coordinate system; obtaining grayscale information of the outer edge of the adhesive strip in the image, and determining the position of the outer edge of the adhesive strip in the image in the coordinate system. By recognizing the grayscale information of the image and establishing a reference coordinate system, the positions of the four sides of the battery and the edges of the adhesive strip can be accurately determined.

[0035] In the related art, the conveyor line moves the batteries that have been glued from the gluing station to the gluing inspection station to inspect whether the battery glue is qualified. If a battery with unqualified glue is detected, the battery needs to be discharged in time to prevent the battery with poor glue from being mixed with qualified batteries.

[0036] When performing the discharge operation of unqualified batteries, there are at least the following problems: when the battery's glue test results are completed at the glue test station and the unqualified batteries are discharged, it is necessary to wait for the robot to discharge the unqualified batteries, which makes it impossible for the glue test station to detect the batteries normally, occupying the production cycle.

[0037] In order to solve the problem that the discharge operation of unqualified batteries occupies the production cycle, the operation of the glue detection mechanism and the discharge operation of unqualified batteries can be set at different stations of the conveyor line, thereby solving the problem that the discharge operation of unqualified batteries occupies the production cycle.

[0038] The batteries bonded by the battery bonding apparatus disclosed in the embodiments of this application can be used, but are not limited to, in electrical devices such as vehicles, ships, or aircraft. Electrical devices can include, but are not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, and the like.

[0039] The technical solution provided by this application is described in more detail below with reference to Figures 1 to 4.

[0040] Referring to Figures 1 to 4, Figure 1 is a schematic diagram of the three-dimensional structure of the battery gluing equipment of an embodiment of the present application; Figure 2 is a schematic diagram of the three-dimensional structure of the glue peeling gripper and the glue detection device of the battery gluing equipment of an embodiment of the present application; Figure 3 is an enlarged view of the glue detection device shown in Figure 2 of the embodiment of the present application; Figure 4 is a schematic diagram of the three-dimensional structure of the transfer mechanism and defective product receiving mechanism of the battery gluing equipment of an embodiment of the present application.

[0041] As shown in Figures 1 to 4, a battery gluing device is provided. The battery gluing device may include a gluing detection mechanism 1 for detecting the gluing results of a battery 20. The battery gluing device may include a defective product receiving mechanism 5 for receiving batteries 20 with unqualified gluing detected by the gluing detection mechanism 1. The battery gluing device may include a transfer mechanism 2 for transferring unqualified batteries 20 detected by the gluing detection mechanism 1 to the defective product receiving mechanism 5. The battery gluing device may include a conveyor line 3 for transferring the batteries 20 from the gluing detection mechanism 1 to the transfer mechanism 2.

[0042] As shown in Figures 1 and 4, the conveyor line 3 transfers the battery 20 shown in Figure 4 (the battery 20 is not shown on the conveyor line 3 in Figure 1) to different workstations. The workstations involved in the battery gluing equipment of the embodiment of the present application may include a glue peeling station, a glue detection station and a defective product discharge station. Defective products refer to batteries 20 that fail the glue testing. The battery 20 transported by the conveyor line 3 can be a battery cell or a battery module composed of battery cells. During the production process of the battery 20, the battery 20 needs to be glued by a rubber strip to fix it to the battery shell or to increase the strength of the battery surface or to prevent the battery surface from being punctured.

[0043] As shown in Figures 1 to 4, at the glue peeling station, the glue peeling gripper 4 tears off the release paper on the surface of the battery 20, and the battery 20 is transferred by the conveyor line 3 to the bottom of the glue detection mechanism 1 of the glue detection station. At the glue detection station, the glue detection mechanism 1 detects the glue results through visual inspection and screens out batteries 20 with poor glue. The batteries 20 that have been inspected by the glue detection mechanism 1 are transferred by the conveyor line 3 to the defective product discharge station. At the defective product discharge station, the transfer mechanism 2 transfers the unqualified batteries 20 away from the conveyor line 3 to the defective product receiving mechanism 5, while the qualified batteries 20 will continue to be transferred on the conveyor line 3 to the downstream equipment.

[0044] The battery gluing equipment provided in this embodiment enables the detection operation of the gluing detection mechanism 1 and the transfer operation of the transfer mechanism 2 for transferring unqualified batteries 20 to be performed at different stations of the battery 20 conveyor line 3. Since the gluing detection station for the detection operation of the gluing detection mechanism 1 is independent of the defective product discharge station for the transfer mechanism 2 to discharge unqualified batteries 20 from the conveyor line 3, the transfer operation of unqualified batteries 20 will not affect the detection operation of the gluing detection mechanism 1, so that the battery discharge operation will not affect the production rhythm.

[0045] In some embodiments, the defective product receiving mechanism 5 may include a discharge line arranged at an angle to the conveying line 3 , and the unqualified batteries 20 are transferred to the discharge line through the transfer mechanism 2 .

[0046] The discharge line of the defective product receiving structure can be arranged to intersect with the conveyor line 3. For example, the discharge line can be arranged transversely to the conveyor line 3 to be perpendicular to each other. The discharge line can be arranged in the form of a belt line or a double-speed chain as needed.

[0047] By adopting a discharge line arranged at an angle relative to the conveyor line 3 , batteries 20 that fail the glue testing can be quickly discharged from the conveyor line 3 to avoid being mixed with qualified batteries 20 transmitted on the conveyor line 3 .

[0048] In some embodiments, the conveyor line 3 has a preset length 8 between the glue-applying detection mechanism 1 and the transfer mechanism 2 for accommodating the batteries 20 that have been inspected by the glue-applying detection mechanism 1 .

[0049] The conveyor line 3 has a preset length 8 reserved between the glue detection mechanism 1 and the transfer mechanism 2. The preset length 8 can be determined based on factors such as the time required for the glue detection mechanism 1 to detect the battery glue results and the time required for the transfer mechanism 2 to transfer unqualified batteries 20.

[0050] The preset length is set so that when the operation time of the transfer mechanism 2 to transfer the unqualified battery 20 is greater than the detection time of the glue detection mechanism 1, the battery 20 that has been inspected by the glue detection mechanism 1 can be accommodated in the preset length 8, so that the inspected battery 20 will not occupy the inspection station and will not affect the production rhythm.

[0051] In some embodiments, the glue detection mechanism 1 is arranged on the first frame 6 of the conveyor line 3 , and the transfer mechanism 2 is arranged on the second frame 7 of the conveyor line 3 .

[0052] At the glue detection station and defective product discharge station of the conveyor line 3, the conveyor line 3 is supported by a first bracket and a second bracket respectively, the glue detection mechanism 1 is arranged on the first frame 6 of the conveyor line 3, and the transfer mechanism 2 is arranged on the second frame 7 of the conveyor line 3.

[0053] The first frame 6 and the second frame 7 provide stable support for the glue detection mechanism 1 and the transfer mechanism 2 .

[0054] In some embodiments, the glue detection mechanism 1 may include: a first frame 9 arranged across the conveyor line 3; a first longitudinal guide rail 10 arranged on the first frame 9 and parallel to the conveyor line 3; and a visual system 11 arranged on the first longitudinal guide rail 10 and capable of moving along the first longitudinal guide rail 10, the visual system 11 being used to detect batteries 20 located on the conveyor line 3.

[0055] The first frame 9 of the adhesive bonding inspection mechanism 1 is arranged across the conveyor line 3, and the first longitudinal guide rail 10 of the adhesive bonding inspection mechanism 1 is supported on the first frame 9. The first longitudinal guide rail 10 is arranged parallel to the conveyor line 3. The vision system 11 for inspecting the batteries 20 on the conveyor line 3 is arranged on the first longitudinal guide rail 10 and can move along the first longitudinal guide rail 10. The first longitudinal guide rail 10 can be arranged in the form of a linear module, for example.

[0056] The above-mentioned structural arrangement of the glue detection mechanism 1 enables the visual system 11 of the glue detection mechanism 1 to be stably supported across the conveyor line 3 and to move parallel to the conveyor line 3 along the longitudinal guide rail.

[0057] In some embodiments, the battery gluing equipment may include at least two parallel conveying lines 3 , and the vision system 11 of the gluing detection mechanism 1 is correspondingly provided with a vision camera 12 for each conveying line 3 .

[0058] The battery gluing equipment can be provided with one conveyor line 3 or two or more conveyor lines 3. In the case where the battery gluing equipment is provided with two or more parallel conveyor lines 3, the visual system 11 of the gluing inspection mechanism 1 can be provided with two or more visual cameras 12 accordingly, for taking pictures of the batteries 20 on each conveyor line 3.

[0059] By providing a vision camera 12 for each conveyor line 3 , it is possible to ensure that the batteries 20 on each conveyor line 3 are inspected.

[0060] In some embodiments, the transfer mechanism 2 may include a battery grasping member 13 and a second frame 14, and the battery grasping member 13 can move in the second frame 14 in a direction parallel to the conveyor line 3 and a direction perpendicular to the conveyor line 3, and can move in the vertical direction, so that the battery grasping member 13 can be aligned with the unqualified glue-applied battery 20 on the conveyor line 3, and can be aligned with the defective product receiving mechanism 5.

[0061] The second frame 14 of the transfer mechanism 2 can be set as a three-axis truss structure, which is used to support the battery grasping component 13 and enable the battery grasping component 13 to move in three directions, namely, in a direction parallel to the conveyor line 3, a direction perpendicular to the conveyor line 3 and a vertical direction, so that the battery grasping component 13 can grasp the unqualified batteries 20 and transfer the unqualified batteries 20 to the defective product receiving mechanism 5.

[0062] In some embodiments, the second frame 14 may include: at least one transverse guide rail 15 arranged across the conveyor line 3; a second longitudinal guide rail 16 extending parallel to the conveyor line 3 and capable of moving on the transverse guide rail 15; and at least one vertical guide rail 17 arranged on the second longitudinal guide rail 16 and capable of moving along the second longitudinal guide rail 16, wherein the battery grabbing member 13 is arranged on the vertical guide rail and can move in a vertical direction along the vertical guide rail.

[0063] The transverse guide rail 15 of the second frame 14 of the transfer mechanism 2 is disposed across the conveyor line 3. One or more transverse guide rails 15 may be provided. In FIG4 of the present embodiment, two transverse guide rails 15 are provided. Those skilled in the art may configure the transverse guide rail 15, the second longitudinal guide rail 16, and the vertical guide rail 17 in various configurations, such as slide rails, linear modules, or lead screws, as needed.

[0064] The provision of the transverse guide rail 15 , the second longitudinal guide rail 16 and the vertical guide rail 17 enables the second frame 14 to guide the battery gripping member 13 to move in a direction parallel to the conveyor line 3 , a direction perpendicular to the conveyor line 3 and a vertical direction.

[0065] In some embodiments, the second frame 14 may include two transverse guide rails 15 , and both ends of the second longitudinal guide rail 16 are supported on the transverse guide rails 15 respectively.

[0066] The second frame 14 is provided with two transverse guide rails 15 , which provide a stable support for the second longitudinal guide rail 16 .

[0067] In some embodiments, the battery gripping member 13 is configured as a robot 18 , and the transfer mechanism 2 includes a number of robots 18 that matches the number of batteries 20 in each battery group transported on the conveyor line 3 .

[0068] According to one embodiment of the present invention, a carrier 19 for batteries 20 is provided on the conveyor line 3, and the batteries 20 are arranged in the carrier 19. The carrier 19 for the batteries 20 is, for example, a tray. In the case where a group of batteries carried in the carrier 19 are batteries 20 with good performance matching, if it is determined that one battery 20 on the carrier 19 is an unqualified battery 20, then the other batteries 20 with matching performance on the carrier 19 also need to be discharged. Therefore, the number of manipulators 18 of the transfer mechanism 2 needs to be consistent with the number of batteries 20 on the carrier 19, so that if one battery 20 on the carrier 19 is unqualified, all batteries 20 on the carrier 19 will be discharged together.

[0069] In some embodiments, the transfer mechanism 2 may include a plurality of manipulators 18 , each manipulator 18 being disposed on a vertical guide rail 17 , and the vertical guide rails 17 being disposed side by side on the second longitudinal guide rail 16 , wherein at least one vertical guide rail 17 is capable of moving along the second longitudinal guide rail.

[0070] For example, the number of manipulators 18 can be set to two, and correspondingly two vertical guide rails 17 are set side by side on the second longitudinal guide rail 16, one of which can be set to move along the second longitudinal guide rail 16, and the other vertical guide rail 17 can be set not to move along the second longitudinal guide rail 16.

[0071] When the transfer mechanism 2 is provided with a plurality of manipulators 18 , the vertical guide rails 17 for guiding the movement of the manipulators 18 can be arranged side by side on the second longitudinal guide rail 16 to facilitate the discharge of a plurality of batteries 20 together and reduce the possibility of mutual interference.

[0072] According to an embodiment of the present application, with reference to Figures 1 to 4, the present application provides a battery gluing device, which may include: a gluing inspection mechanism 1 for inspecting the gluing results of batteries 20 contained in a carrier 19; a defective product receiving mechanism 5 for receiving defective batteries 20 inspected by the gluing inspection mechanism 1; a transfer mechanism 2 for transferring defective batteries 20 inspected by the gluing inspection mechanism 1 to the defective product receiving mechanism 5; and a conveyor line 3 for transferring the carrier 19 carrying the batteries 20 from the gluing inspection mechanism 1 to the transfer mechanism 2. The carrier 19 may accommodate two batteries 20 of matching performance, and the transfer mechanism 2 may be provided with two battery gripping members 13. When the gluing inspection mechanism 1 detects that one of the batteries 20 in the carrier 19 is defective, the two battery gripping members 13 are used to cause both batteries 20 in the carrier 19 to leave the conveyor line 3 and be discharged to the defective product receiving mechanism 5.

[0073] An embodiment of the present application provides a battery gluing method, which may include: using a gluing detection mechanism 1 to detect the gluing results of a battery 20; associating the unqualified detection results with the identification information of the battery 20 with unqualified gluing; using a conveyor line 3 to transmit the detected battery 20 to a transfer mechanism 2; identifying the identification information of the battery 20 on the conveyor line 3 to determine whether there is a battery 20 with unqualified gluing; if so, using the transfer mechanism 2 to transfer the unqualified battery 20 on the conveyor line 3 to a defective product receiving mechanism 5.

[0074] Each electrical component, including the adhesive application inspection mechanism 1, conveyor line 3, and transfer mechanism 2, is communicatively connected to the production line's control system, such as a programmable logic controller (PLC). At the adhesive application inspection station, the adhesive application inspection mechanism 1 uploads the photographic results to the PLC. The PLC compares the photographed dimensions of the battery 20 with the dimensions of the adhesive strip to determine if the adhesive application on the battery 20 is acceptable. The PLC binds the comparison result to the battery 20's identification information in the form of data. At the defective product removal station, the PLC reads the battery 20's identification information to determine whether to remove the defective battery 20.

[0075] When the battery 20 is disposed in the carrier 19 , identification information of the battery 20 may be bound to identification information of the carrier 19 , such as RFID of the carrier 19 .

[0076] The battery gluing method provided in this embodiment enables the operation of the transfer mechanism 2 for discharging unqualified batteries 20 to be performed at a downstream station of the station where the gluing detection mechanism 1 is located on the conveyor line 3, so that the detection operation of the gluing detection mechanism 1 and the operation of the transfer mechanism 2 for transferring unqualified batteries 20 are performed at two different stations of the battery conveyor line 3, so that the transfer operation of the unqualified batteries 20 will not affect the detection operation of the gluing detection mechanism 1, and will not affect the production rhythm.

[0077] In some embodiments, using the glue detection mechanism 1 to detect the glue results of the battery 20 may include: using the glue detection mechanism 1 to collect size information of the glue strip and size information of the battery 20, and determining whether to generate an unqualified detection result based on a comparison of the collected size information of the glue strip and the collected size information of the battery 20.

[0078] The adhesive testing mechanism 1 collects the size information of the adhesive strip and the size information of the battery 20 , and the PLC of the production line compares the collected size information of the adhesive strip with the collected size information of the battery 20 to determine whether to generate an unqualified test result.

[0079] By collecting and comparing the size information of the adhesive strip and the size information of the battery 20 , basic information for generating the test result is determined.

[0080] In some embodiments, using the adhesive detection mechanism 1 to collect the size information of the adhesive strip and the size information of the battery 20 may include: collecting an image of the battery 20 carrying the adhesive strip; determining the positions of the four sides of the battery 20 and the positions of the edges of the adhesive strip based on the recognition of the image, and determining whether to generate an unqualified detection result based on the comparison of the collected size information of the adhesive strip with the collected size information of the battery 20 may include: respectively calculating the distance from the edge of each adhesive strip to the corresponding edge of the four sides of the battery 20; if the distance from the edge of any adhesive strip to the corresponding edge of the battery 20 does not meet the predetermined tolerance range, an unqualified detection result is generated.

[0081] The adhesive strip inspection mechanism 15 captures image information of the battery 20 and the adhesive strip. The PLC determines the position of the edges of the battery 20 and the adhesive strip based on this image information, thereby obtaining dimensional information. The PLC calculates the distance from the edge of the adhesive strip to the corresponding of the four sides of the battery 20 to determine whether each distance meets the predetermined tolerance range. If all distances meet the predetermined tolerance range, a qualified test result is generated. If any of the distances does not meet the predetermined tolerance range, a failed test result is generated.

[0082] By comparing the precise distance between the battery 20 and the rubber strip, the accuracy of the detection result is guaranteed.

[0083] In some embodiments, determining the positions of the four sides of the battery 20 and the positions of the edges of the adhesive strip based on image recognition may include: obtaining grayscale information of the two intersecting edges of the battery 20 in the image, and establishing a coordinate system with the intersection of the two intersecting edges of the battery 20 in the image as the origin; obtaining grayscale information of the four sides of the battery 20 in the image, and determining the positions of the four sides of the battery 20 in the coordinate system; obtaining grayscale information of the outer edge of the adhesive strip in the image, and determining the position of the outer edge of the adhesive strip in the coordinate system.

[0084] By identifying the grayscale information of the image and establishing a coordinate system, the positions of the four sides of the battery 20 and the sides of the adhesive strip in the image can be quickly determined.

[0085] According to an embodiment of the present application, a battery gluing method is provided, which may include: using a gluing detection mechanism 1 to detect the gluing results of the battery 20; associating the unqualified detection results with the identification information of the tray 19 carrying the battery 20 with unqualified gluing; using the conveyor line 3 to transfer the tray 19 carrying the inspected batteries 20 to the transfer mechanism 2; identifying the identification information of the tray 19 carrying the battery 20 on the conveyor line 3 to determine whether there is a tray 19 carrying the battery 20 with unqualified gluing; if so, using the transfer mechanism 2 to transfer all the batteries on the tray 19 carrying the unqualified batteries 20 on the conveyor line 3 to the defective product receiving mechanism 5.
