[0038] Reference Figures 1 to 7 As shown, one embodiment of the battery adhesive fixing device of this utility model is used for bonding adhesive tape 200 and battery cell 100. A thin film is connected to a portion of the end face of the battery cell 100, and the thin film portion extends out of the battery cell 100. That is, the thin film portion is placed on the outside of the long strip edge 110 of the battery cell 100.

[0039] Reference Figure 1 , Figure 2 and Figure 5 As shown, the adhesive tape 200 of the battery bonding and fixing device includes a first sub-tape 210, a second sub-tape 220 and a third sub-tape 230 connected in sequence. The second sub-tape 220 is arranged at a right angle to the first sub-tape 210 and the third sub-tape 230, and the upper end and the lower end of the second sub-tape 220 are connected to the first sub-tape 210 and the third sub-tape 230 respectively, so that the adhesive tape 200 forms a slot, and the slot fits into the side of the battery cell 100.

[0040] Specifically, the slot engages with the elongated side 110 of the battery cell 100. The second sub-tape 220 is arranged at right angles to the first sub-tape 210 and the third sub-tape 230. The adhesive tape 200 has an adhesive layer on the inner wall of the slot to facilitate adhesion between the adhesive tape 200 and the battery cell 100. The adhesive tape 200 has an extension protruding from the side of the battery cell 100; specifically, the extension protrudes along the length of the battery cell 100.

[0041] Reference Figure 1 , Figure 2 and Figure 5 As shown, the first sub-strip 210 and the third sub-strip 230 are connected to the upper and lower ends of the battery cell 100, respectively. A pressing space 240 is constructed between the end corner 120 of the battery cell 100 and the tape 200. The pressing space 240 allows the kneading assembly 400 to press the tape 200, so as to achieve the covering of the end corner 120 and the film of the battery cell 100 by the tape 200.

[0042] Reference Figure 1 , Figure 3 and Figure 4As shown, the telescopic actuator 500 is connected to the pusher block 300 to drive the pusher block 300 to press against the middle of the second sub-belt 220, causing the middle of the second sub-belt 220 to fold inward into the pressing space 240, forming an upper belt 221 and a lower belt 222 arranged at an angle. The middle of the second sub-belt 220 along its height direction abuts against the pusher block 300, and an indentation is formed at the abutment point between the pusher block 300 and the second sub-belt 220. Specifically, the pusher block 300 is in the shape of an elongated rod. The pusher block 300 is configured to move closer to or further away from the end corner 120 of the cell 100.

[0043] Reference Figure 1 , Figure 3 and Figure 4 As shown, the kneading assembly 400 includes a tensioning driver, an upper clamping block 410, and a lower clamping block 420. The tensioning driver is connected to the upper clamping block 410 and the lower clamping block 420 to drive the upper clamping block 410 and the lower clamping block 420 toward or away from the tape 200. The tensioning driver is configured to press the first sub-tape 210 and the third sub-tape 230 against the upper tape 221 and the lower tape 222, respectively.

[0044] Reference Figure 1 , Figure 3 and Figure 4 As shown, the opening and closing driver is connected to the upper clamping block 410 and the lower clamping block 420 to drive the upper clamping block 410 and the lower clamping block 420 to move closer to or further away from the tape 200. Under the joint squeezing action of the upper clamping block 410 and the lower clamping block 420, the second sub-tape 220 is pressed along the indentation in its middle part, which can press the first sub-tape 210 with the upper tape 221 and the third sub-tape 230 with the lower tape 222, so that the extension is pinched into a flat shape, that is, the part of the tape 200 protruding from the battery cell 100 is pinched into a flat shape, so as to achieve the fixation of the tape 200 and the battery cell 100, so as to complete the packaging and protection of the end corner 120 and the film of the battery cell 100 by the tape 200, which is beneficial to improve the adhesive quality of the battery cell 100.

[0045] Specifically, the pressing space 240 is divided into an upper chamber and a lower chamber along the indentation. The upper chamber is defined by the lower end face of the first sub-tape 210, the inner wall face of the upper tape 221, and the end corner 120 of the battery cell 100. The lower chamber is defined by the upper end face of the third sub-tape 230, the inner wall face of the lower tape 222, and the end corner 120 of the battery cell 100. Under the action of the kneading assembly 400, the lower end face of the first sub-tape 210 is pressed against the inner wall face of the upper tape 221, and the upper end face of the third sub-tape 230 is pressed against the inner wall face of the lower tape 222.

[0046] Reference Figure 1 , Figure 3 and Figure 4As shown, it is understandable that, considering the difficulty in controlling the adhesive application at the four corners 120 of the battery cell 100, two adhesive tapes 200 are provided for each battery cell 100. The two tapes 200 are respectively connected to both ends of the battery cell 100 along its width direction, and each tape 200 is fitted into one of the two elongated sides 110 of the battery cell 100. Furthermore, the length of the tape 200 is greater than the length of the elongated side 110 of the battery cell 100, so that one tape 200 can cover the two corners 120 of the battery cell 100 located on the same side, thereby achieving packaging and protection of the corners 120 of the battery cell 100.

[0047] Reference Figure 1 , Figure 3 and Figure 4 As shown, the adapted battery adhesive fixing device comprises a pusher block 300, a telescopic driver 500, and a pinching adhesive assembly 400 forming an adhesive pressing mechanism. Four adhesive pressing mechanisms are provided, each corresponding to one of the four end corners 120 of the battery cell 100. By applying adhesive pressing treatment to the battery cell 100 at the four end corners 120, the bonding effect between the adhesive tape 200 and the battery cell 100 is improved, thereby achieving the connection between the two adhesive tapes 200 and the battery cell 100.

[0048] Reference Figure 1 , Figure 3 and Figure 4 As shown, for a battery cell 100 with an arc-shaped end corner 120, traditional adhesive application equipment has difficulty in packaging and protecting the end corner 120 of the battery cell 100. However, the battery adhesive application and fixing device provided in this embodiment of the utility model uses the tape 200 to fit into the end corner 120 of the battery cell 100, in conjunction with the push block 300 and the telescopic driver 500, to drive the second sub-tape 220 to fold inward toward the end corner 120 of the battery cell 100. With the position arrangement of the pinching assembly 400, the tape 200 can package and protect the end corner 120 and the film of the battery cell 100.

[0049] Reference Figure 3 , Figure 4 and Figure 6 As shown, specifically, considering that the end corners 120 of some battery cells 100 are arc-shaped, in order to improve the adhesive or wrapping effect of the tape 200 on the end corners 120 of the battery cells 100, the pusher block 300 is configured to move closer to or further away from the end corners 120 of the battery cells 100, driving the second sub-tape 220 to fold towards the end corners 120 of the battery cells 100, so as to enhance the correspondence between the second sub-tape 220 and the end corners 120 of the battery cells 100. That is, by controlling the squeezing position of the pusher 300 and the second sub-tape 220, the tape 200 can cover the arc-shaped end corners 120, thereby improving the adhesive effect of the tape 200 on the end corners 120 of the battery cells 100.

[0050] Reference Figure 3 , Figure 4 and Figure 7 As shown, the adhesive pinching assembly 400 is configured to apply pressure to the area of ​​the tape 200 near the end corner 120 of the cell 100, so that the tape 200 is pressed together in the area near the end corner 120 of the cell 100, thereby enhancing the correspondence between the second sub-tape 220 and the end corner 120 of the cell 100 and ensuring the adhesive effect of the tape 200 on the end corner 120 of the cell 100.

[0051] It should be noted that the indentation formed on the second sub-tape 220 can guide the pressing of the second sub-tape 220, so that after the pinch assembly 400 presses the tape 200, the shape of the tape 200 after pressing is more regular and the tape 200 is flat.

[0052] Reference Figure 1 , Figure 3 and Figure 4 As shown, it is understood that the pressing mechanism also includes a base plate 710, and the telescopic actuator 500 includes a fixed seat 510 and a movable seat 520 that are capable of telescopic movement. The fixed seat 510 is connected to the base plate 710, and the push block 300 and the pinching assembly 400 are both connected to the movable seat 520.

[0053] Reference Figure 1 , Figure 3 and Figure 4 As shown, the fixed seat 510 is connected to the base plate 710, which provides support for the fixed seat 510 to fix the position of the base. The push block 300 and the pinching assembly 400 are both connected to the movable seat 520. When the movable seat 520 extends relative to the fixed seat 510, the push block 300 can first abut against the second sub-belt 220 of the tape 200, so that the second sub-belt 220 is folded inward to form the upper belt 221 and the lower belt 222.

[0054] The pinching assembly 400 can drive the upper clamping block 410 and the lower clamping block 420 to move closer to the tape 200. Under the joint squeezing action of the upper clamping block 410 and the lower clamping block 420, the second sub-tape 220 is pressed along the indentation in its middle, which can press the first sub-tape 210 with the upper tape 221 and the third sub-tape 230 with the lower tape 222. This makes the part of the tape 200 protruding from the battery cell 100 flattened, so as to fix the tape 200 to the battery cell 100, thereby completing the packaging and protection of the battery cell 100 and the film by the tape 200, which is beneficial to improving the adhesive quality of the battery cell 100.

[0055] Reference Figure 1 , Figure 3 and Figure 5As shown, when the movable seat 520 is in a retracted state relative to the fixed seat 510, the opening and closing driver drives the upper clamping block 410 and the lower clamping block 420 to move away from each other, so that a pinching space is formed between the upper clamping block 410 and the lower clamping block 420, and the end of the push block away from the movable seat 520 is adjacent to the pinching space.

[0056] Reference Figure 3 , Figure 6 and Figure 7 As shown, when the telescopic actuator 500 operates, the movable seat 520 extends relative to the fixed seat 510. The movable seat 520 moves closer to the battery cell 100 and the tape 200. The end of the push block 300 away from the movable seat 520 first abuts against the second sub-tape 220, causing the second sub-tape 220 to fold inward and form an upper tape 221 and a lower tape 222 arranged at an angle. The upper tape 221 and the lower tape 222 are both placed in the pinching space, that is, the upper clamping block 410 is located above the first sub-tape 210 and the upper tape 221, and the lower clamping block 420 is located below the third sub-tape 230 and the lower tape 222. Under the driving action of the opening and closing actuator, the upper clamping block 410 and the lower clamping block 420 move closer to each other, thereby pressing the first sub-tape 210 and the third sub-tape 230 against the upper tape 221 and the lower tape 222 respectively, so that the portion of the tape 200 protruding in the width direction of the battery cell 100 is pinched into a flat shape.

[0057] Reference Figure 3 , Figure 6 and Figure 7 As shown, it should be noted that the telescopic actuator 500 is a linear drive mechanism such as an electric actuator, pneumatic actuator, hydraulic actuator, lead screw slider mechanism, and crank connecting rod mechanism.

[0058] It should be understood that in some other embodiments, the lower end of the upper clamping block 410 is provided with an elastic rubber pad, and the upper end of the lower clamping block 420 is provided with an elastic rubber pad. When the movable seat 520 extends into position relative to the fixed seat 510, the long strip edge 110 of the battery cell 100 is located in the pinching space, that is, the pinching assembly 400 can achieve joint pressing of the tape 200 and the battery cell 100. Through the deformation of the elastic rubber pad at the lower end of the upper clamping block 410 and the elastic rubber pad at the upper end of the lower clamping block 420, the portion of the tape 200 protruding in the length direction of the battery cell 100 is pinched into a flat shape.

[0059] Reference Figure 1 , Figure 3 and Figure 4 As shown, it can be understood that in this embodiment, the pressing mechanism further includes a rotating block 600 and a limiting member 800. The rotating block 600 is rotatably connected to the movable seat 520. The rotating block 600 can rotate relative to the movable seat 520 about an axis extending vertically. The pressing mechanism also includes a rotating shaft, which passes through the rotating block 600 and the movable seat 520 so that the rotating block 600 and the movable seat 520 can rotate about the rotating shaft.

[0060] Reference Figure 1 , Figure 3 and Figure 4 As shown, the limiting member 800 is configured to fix the rotation angle between the rotating block 600 and the movable seat 520, and the push block 300 and the pinching assembly 400 are both connected to the rotating block 600.

[0061] Reference Figure 1 , Figure 3 and Figure 4 As shown, the push block 300 and the pinching component 400 are both connected to the rotating block 600, so that the user can adjust the relative position of the push block 300 and the pinching component 400 relative to the battery cell 100 according to the different shapes and sizes of the battery cell 100 and the actual adhesive application effect. After the adjustment is in place, the user can fix the rotation angle between the rotating block 600 and the movable seat 520 through the limiting component 800, so that the battery adhesive fixing device can be adapted to various battery cells 100 and meet the usage needs of different scenarios.

[0062] Reference Figure 1 , Figure 3 and Figure 4 As shown, it can be understood that the rotating block 600 is provided with an arc-shaped hole 610, the movable seat 520 has a mounting hole opposite to the arc-shaped hole 610, and the limiting member 800 is configured to slide along the arc-shaped hole 610. The limiting member 800 passes through the arc-shaped hole 610 and is connected to the mounting hole to fix the rotating block 600 and the movable seat 520.

[0063] Reference Figure 1 , Figure 3 and Figure 4 As shown, as the rotating block 600 rotates relative to the movable seat 520, the position of the limiting member 800 within the arc-shaped hole 610 can be changed. The movable seat 520 has a mounting hole opposite to the arc-shaped hole 610. The limiting member 800 passes through the arc-shaped hole 610 and is connected to the mounting hole. By pressing the movable seat 520 and the rotating block 600 together with the limiting member 800, the rotation angle between the movable seat 520 and the rotating block 600 is fixed.

[0064] Reference Figure 1 , Figure 3 and Figure 4As shown, specifically, the limiting member 800 is a threaded connector, and the mounting hole is a threaded hole. After passing through the arc-shaped hole 610, the threaded connector can be threadedly connected to the threaded hole. The user can rotate the threaded connector to disengage it from the threaded hole, thereby reducing or eliminating the pressure of the threaded connector on the rotating block 600, allowing the rotating block 600 to rotate relative to the movable seat 520, thus adjusting the rotation angle between the rotating block 600 and the movable seat 520. After the rotating block 600 and the movable seat 520 are adjusted to their positions, the user can rotate the threaded connector to screw it into the threaded hole. The head of the threaded connector abuts against the rotating block 600, thereby applying pressure to the rotating block 600 and the movable seat 520 to fix their relative positions.

[0065] Reference Figure 1 , Figure 3 and Figure 4 As shown, it can be understood that the push block 300 includes a first sub-block 310 and a second sub-block 320 arranged at an angle. The two ends of the first sub-block 310 are connected to the rotating block 600 and the second sub-block 320 respectively. The length direction of the second sub-block 320 is consistent with the extension and retraction direction of the telescopic actuator 500.

[0066] Reference Figure 1 , Figure 3 and Figure 4 As shown, the push block 300 includes a first sub-block 310 and a second sub-block 320 arranged at an angle. The first sub-block 310 and the second sub-block 320 are arranged at right angles. The two ends of the first sub-block 310 are connected to the rotating block 600 and the second sub-block 320, respectively. The length direction of the second sub-block 320 is consistent with the extension direction of the telescopic driver 500, that is, the second sub-block 320 is used to squeeze the second sub-belt 220. The first sub-block 310 is arranged so that the second sub-block 320 avoids the pinching assembly 400, thus avoiding the problem that the pinching assembly 400 hinders the extension of the second sub-block 320.

[0067] Reference Figure 1 , Figure 3 and Figure 4 As shown, specifically, the push block 300 also includes a third sub-block connected to the first sub-block 310. The third sub-block is arranged at a right angle to the first sub-block 310. The third sub-block is used to connect with the rotating block 600. The first sub-block 310, the second sub-block 320, and the third sub-block can be made from the same material through a bending process to improve the connection stability of the first sub-block 310, the second sub-block 320, and the third sub-block.

[0068] Reference Figure 1 , Figure 3 and Figure 4As shown, it can be understood that the thickness of the push block 300 at the end that abuts against the second sub-tape 220 is less than the thickness of the second sub-tape 220 in the vertical direction. When the push block 300 abuts against the second sub-tape 220, the middle part of the second sub-tape 220 can be folded into the interior of the pressing space 240 and separated into an upper tape 221 and a lower tape 222 along the middle indentation. With the cooperation of the pinching assembly 400, under the joint squeezing action of the upper clamping block 410 and the lower clamping block 420, the second sub-tape 220 is pressed along the middle indentation, so that the first sub-tape 210 is pressed with the upper tape 221 and the third sub-tape 230 is pressed with the lower tape 222. This makes the part of the tape 200 protruding from the battery cell 100 flattened, so as to fix the tape 200 to the battery cell 100, thereby completing the packaging and protection of the battery cell 100 and the film by the tape 200, which is beneficial to improving the adhesive quality of the battery cell 100.

[0069] Reference Figure 1 , Figure 3 and Figure 4 As shown, specifically, the second sub-block 320 has an abutment section at the end away from the first sub-block 310. The thickness of the abutment section gradually decreases in the direction away from the first sub-block 310, so that the abutment section can abut and squeeze the middle of the second sub-belt 220, so that the middle of the second sub-belt 220 folds towards the pressing space 240 and forms an upper belt 221 and a lower belt 222 arranged at an angle.

[0070] Reference Figure 1 , Figure 3 and Figure 4 As shown, it is understood that the push block 300 and the rotating block 600 are detachably connected so that users can select different types of push blocks 300 to use according to different shapes or sizes of battery cells 100, thereby improving the applicability of the battery adhesive fixing device to different battery cells 100.

[0071] Reference Figure 1 , Figure 3 and Figure 4 As shown, specifically, the rotating block 600 is provided with a screw hole, and the third sub-block of the push block 300 is provided with a second through hole. The user can use a threaded connector to pass through the second through hole and connect it with the screw hole on the rotating block 600, so that the push block 300 and the rotating block 600 can be detachably connected, so that the user can replace the push block 300 with different styles and sizes according to actual needs.

[0072] Reference Figure 1 , Figure 3 and Figure 4As shown, it can be understood that one end of the pinching assembly 400 is connected to the movable seat 520, and the other end is inclined toward the end corner 120 of the battery cell 100. The pinching assembly 400 and the push block 300 are arranged at an angle. The push block 300 is configured to drive the second sub-tape 220 toward the end corner 120 of the battery cell 100 to enhance the correspondence between the second sub-tape 220 and the end corner 120 of the battery cell 100. At the same time, one end of the pinching assembly 400 is connected to the movable seat 520, and the other end is inclined toward the end corner 120 of the battery cell 100 so that the tape 200 is pressed in the area near the end corner 120 of the battery cell 100 to enhance the correspondence between the second sub-tape 220 and the end corner 120 of the battery cell 100 and ensure the adhesive effect of the tape 200 on the end corner 120 of the battery cell 100.

[0073] Reference Figure 1 , Figure 3 and Figure 4 As shown, it can be understood that, specifically, the movable seat 520 is connected to a stop block 720, and the base plate 710 is connected to a stop block 730. The stop block 720 moves linearly back and forth as the movable seat 520 extends and retracts. The stop block 720 can abut against the stop block 730 to limit the extension stroke of the movable seat 520 relative to the fixed seat 510, which helps to improve the control accuracy of the extension and retraction of the movable seat 520 relative to the fixed seat 510.

[0074] Reference Figure 1 , Figure 3 and Figure 4 As shown, specifically, the base plate 710 is provided with multiple mounting positions arranged in a straight line. Users can install the stop block 730 at different mounting positions to adjust the contact position between the stop block 730 and the stop block 720, thereby adjusting the extension stroke of the limiting movable seat 520 relative to the fixed seat 510, so as to improve the applicability of the battery adhesive fixing device to different scenarios and make the adjustment of the battery adhesive fixing device more flexible.

[0075] Reference Figure 1 , Figure 3 and Figure 4 As shown, it can be understood that the kneading assembly 400 also includes a connecting seat 430 and a first slider 440 and a second slider 450 arranged vertically. The first slider 440 and the second slider 450 are both slidably connected to the connecting seat 430 in the vertical direction. The opening and closing driver is used to drive the first slider 440 and the second slider 450 to move closer or further apart from each other. The upper clamping block 410 is detachably connected to the first slider 440, and the lower clamping block 420 is detachably connected to the second slider 450.

[0076] Reference Figure 1 , Figure 3 and Figure 4As shown, the adhesive-pressing assembly 400 is slidably connected to the connecting seat 430 via the first slider 440 and the second slider 450, making the movement of the upper clamping block 410 and the lower clamping block 420 more stable and reliable. The upper clamping block 410 is detachably connected to the first slider 440, and the lower clamping block 420 is detachably connected to the second slider 450. Users can select different types and shapes of upper clamping blocks 410 and lower clamping blocks 420 according to the different shapes and sizes of the battery cell 100, which helps to improve the adaptability of the battery adhesive fixing device to different battery cells 100.

[0077] Reference Figure 1 , Figure 3 and Figure 4 As shown, specifically, the upper clamping block 410 has a first through hole, and the first slider 440 has a threaded hole. A user can thread a threaded connector through the first through hole and then connect it to the threaded hole of the first slider 440. The engagement of the threaded connector with the threaded hole of the first slider 440 allows for a detachable connection between the upper clamping block 410 and the first slider 440. The lower clamping block 420 has a second through hole, and the second slider 450 has a threaded hole. A user can thread a threaded connector through the second through hole and then connect it to the threaded hole of the second slider 450. The engagement of the threaded connector with the threaded hole of the second slider 450 allows for a detachable connection between the lower clamping block 420 and the second slider 450.

[0078] It should be noted that the opening and closing actuator can be a linear drive mechanism such as an electric actuator, a hydraulic actuator, a pneumatic actuator, a lead screw and slider mechanism, or a crank and connecting rod mechanism.
