[0033] Specifically, the side panel gluing device includes a tray 1 , a frame 2 , a turning device 3 , a gluing component 4 and a driving system 5 .

[0034] The tray 1 is detachably arranged on the frame 2 .

[0035] The flipping device 3 is disposed on the pallet 1, and is used to install the side plate 12 to be coated with glue, and is used to drive the side plate 12 to rotate until the glue-coated surface of the side plate 12 faces the side or upper part of the pallet 1. For example, Figure 1 As shown, the side of the tray 1 is Figure 1 The left or right side of the tray 1 is Figure 1 Optionally, refer to Figure 3 As shown, the flip device 3 may include a flip seat and a rotation drive device, the flip seat is rotationally connected to the tray 1, the rotation drive device is installed on the tray 1 and connected to the flip seat, and the rotation drive device is used to drive the flip seat to rotate. Optionally, a mounting seat is provided on the flip seat, and a slot is provided on the mounting seat, and the side plate 12 is inserted into the slot of the mounting seat. Optionally, the rotation drive device is set as a motor or a rotary cylinder.

[0036] The driving system 5 is arranged on one side of the tray 1, and the gluing component 4 is installed on the driving system 5. The gluing component 4 is used for gluing, and the driving device is used to drive the gluing component 4 to move along the gluing surface of the side plate 12 so that the gluing component 4 can glue on the gluing surface.

[0037] The side panel gluing device provided in the embodiment of the utility model is detachably connected to the frame 2 through the pallet 1, and the pallet 1 carrying the side panel 12 can be transferred as a whole to the frame 2. When gluing is required, the flipping device 3 drives the gluing surface toward the side of the pallet 1, so that the driving system 5 drives the gluing component 4 to move along the gluing surface of the side panel 12 and apply glue. After the gluing is completed, the flipping device 3 drives the gluing surface toward the upper part of the pallet 1 to avoid glue dripping on the gluing surface.

[0038] With such an arrangement, the side panel gluing device provided in the embodiment of the utility model drives the gluing assembly 4 to gluing the side panel 12 through the driving system 5. Compared with the gluing method in the prior art, it omits the tearing process and the regularizing process, simplifies the gluing process, and improves the gluing efficiency.

[0039] In some embodiments provided by the present invention, the driving system 5 includes a first linear module 501, a second linear module 502, and a third linear module 503 connected in sequence, and the moving directions of the first linear module 501, the second linear module 502, and the third linear module 503 are not aligned. For example, the moving directions of the first linear module 501, the second linear module 502, and the third linear module 503 are perpendicular. The glue coating component 4 is disposed on the third linear module 503.

[0040] In this embodiment, the first linear module 501, the second linear module 502 and the third linear module 503 drive the glue coating assembly 4 to move in three directions, so that the glue coating assembly 4 can not only run along the glue coating surface of the side plate 12 to complete the glue coating on the glue coating surface, but also move closer to or farther away from the direction perpendicular to the glue coating surface, so as to apply glue of different thicknesses to different positions of the glue coating surface, or move away from the glue coating surface after glue coating is completed to avoid the side plate 12 and the tray 1, so as to facilitate the placement and removal of the tray 1.

[0041] Optionally, at least one of the first linear module 501 , the second linear module 502 and the third linear module 503 is configured as a screw module or a rack and pinion module.

[0042] Optionally, the driving system 5 also includes a control component, which connects the first linear module 501, the second linear module 502 and the third linear module 503 respectively, and controls the movement of the first linear module 501, the second linear module 502 and the third linear module 503 to drive the gluing component 4 to complete the gluing step.

[0043] In some embodiments provided by the utility model, the side panel gluing device further includes at least one of a profile scanning device 7 and a height detection device 8. The tray 1 is also used to install the battery 6. For example, the battery 6 and the side panel 12 are arranged side by side on the tray 1, and the side panel 12 is arranged on the outside of the installation surface of the battery 6, and the installation surface is the side surface for installing the side panel 12.

[0044] The contour scanning device 7 and the height detection device 8 are installed on the drive system 5. For example, the contour scanning device 7 and the height detection device 8 can be set on the second linear module 502. Of course, the contour scanning device 7 and the height detection device 8 can also be set on the third linear module 503. The contour scanning device 7 is used to scan and obtain the three-dimensional data of the side of the battery 6, and the height detection device 8 is used to detect the height value of each battery cell on the side of the battery 6. The contour scanning device 7 and the height detection device 8 are electrically connected to the drive system 5. In this embodiment, the drive system 5 can control the operating state of the glue coating component 4 based on the three-dimensional data and the height value of each battery cell.

[0045] In this embodiment, optionally, the contour scanning device 7 and the height detection device 8 are electrically connected to the control component of the drive system 5 .

[0046] In this embodiment, optionally, the contour scanning device 7 can be a 3D contour scanning camera, a laser scanner or a contour scanner.

[0047] In this embodiment, the height detection device 8 can be optionally a photoelectric sensor, which emits a light beam to illuminate the surface of the battery cell. When the light beam encounters the surface of the battery cell, a portion of the light is reflected back to the sensor. After receiving the reflected light signal, the sensor calculates the reflection time of the signal and the speed of light to determine the height of the battery cell.

[0048] Alternatively, the height detection device 8 may also be an ultrasonic sensor, which can emit ultrasonic waves and receive the reflected signals. When the ultrasonic waves encounter the battery cell, they are reflected back and received by the sensor. By measuring the emission and reception time of the ultrasonic waves and combining the propagation speed of the ultrasonic waves in the air, the height of the battery cell can be calculated.

[0049] Alternatively, the height detection device 8 may also be a laser rangefinder, which calculates the distance by emitting a laser beam and measuring the time it takes for it to reflect back. The height of the battery cell can be measured by aiming the laser rangefinder at the top of the battery cell.

[0050] Optionally, the control component can obtain the flatness of the side of the battery 6 according to the three-dimensional data, and the low-lying part and the protruding part of the side of the battery 6 can be determined based on the flatness. At the position where the side plate 12 corresponds to the low-lying part of the side of the battery 6, the running speed of the glue-coating component 4 can be reduced or the glue-coating path of the glue-coating component 4 can be increased, thereby increasing the amount of glue and ensuring that the side plate 12 is tightly fitted to the side of the battery 6. At the position where the side plate 12 corresponds to the protruding part of the side of the battery 6, the running speed of the glue-coating component 4 can be increased or the glue-coating path of the glue-coating component 4 can be reduced, thereby reducing the amount of glue and avoiding the side plate 12 from overflowing after the side plate 12 is fitted to the side of the battery 6. Similarly, the amount of glue is reduced in the part of the side plate 12 corresponding to the higher battery cell to avoid overflowing glue, and the amount of glue is increased in the part of the side plate 12 corresponding to the lower battery cell. For example, the height value of the battery cell can be compared with the height of the end plate of the battery 6, and the corresponding preset threshold interval can be set to judge the height of the battery cell.

[0053] In this embodiment, the position of the glue nozzle 404 relative to the glue gun 401 can be adjusted by adjusting the position of the slider 403 on the guide structure 402, which facilitates the debugging of the position of the glue nozzle 404 so that the glue nozzle 404 is in the correct initial position, that is, the position of the glue nozzle 404 relative to the glue gun 401 can be conveniently adjusted so that the glue nozzle 404 maintains an appropriate gap with the side panel 12 during the gluing process.

[0054] Optionally, a fastening screw may be provided on the slider 403, the fastening screw is threadedly connected to the slider 403, and abuts against or disengages from the guide structure 402 to lock or unlock the slider 403. Of course, the slider 403 may also be moved under the drive of the motor and the lead screw.

In addition, in order to maintain the stability of the pallet 1 during the gluing process, the pallet 1 can be clamped and fixed by the two centering seats 10.

[0057] In this embodiment, optionally, refer to Figure 1 As shown, in the horizontal direction, the centering seat 10 overlaps with the flip seat. Therefore, in order to allow the centering seat 10 to avoid the glue coating component 4, the contour scanning device 7 or the height detection device 8, a through avoidance groove is provided on the centering seat 10.

For example, the motor, the lead screw and the centering seat 10 correspond to each other one by one, the motor is installed on the frame 2, the lead screw is connected to the output shaft of the corresponding motor, and the lead screw is threadedly connected to the corresponding centering seat 10. Of course, only one set of motor and lead screw can be provided, and the lead screw is provided with two sections of threads with opposite rotation directions, which are respectively threadedly connected to the two centering seats 10.

[0062] In this embodiment, during the gluing process, the tray 1 can be driven to rise by the lifting drive device, so that the tray 1 rises between the two centering seats 10, so that the two centering seats 10 can clamp the tray 1. When the tray 1 needs to be taken and placed, the two centering seats 10 move away from each other, and the lifting drive device drives the tray 1 to descend to increase the operable space above the tray 1, thereby facilitating a mechanism such as a robot to enter above the tray 1 and perform a take-and-place operation on the tray 1.
