[0002] The cells of common square batteries are mostly dual-core or quad-core structures. During the shelling process, in order to facilitate the shelling process, the bottom and both sides of the cell formed by stacking multiple core packages together will be glued and bound.

[0003] In the related art, a gluing device with announcement number CN214848726U and a gluing assembly and gluing system with announcement number CN217062208U both use upper and lower cross arms and brushes to perform U-shaped gluing on the ends of the battery cells to ensure that the ends of the tape are smoothed by the brushes without curling up. However, except for the parts of the tape squeezed by the brushes at the ends, the remaining middle section lacks the corresponding squeezing structure to ensure that the tape is flat and tightly attached to the end surface of the battery cell, and the flatness and tightness of the middle section of the tape are difficult to ensure.

[0004] Therefore, it is necessary to study and improve the above structure and provide a glue sticking mechanism in order to achieve a more practical purpose. Summary of the invention

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] In view of the shortcomings or one of the shortcomings of the above-mentioned technology, the embodiment of the present application provides a gluing mechanism to further improve the gluing effect of the end of the battery cell and ensure the flatness and tightness of the tape on the battery cell.

[0030] See also Figures 1 to 3 As shown, the embodiment of the present application provides a glue sticking mechanism, including:

[0031] A side attachment assembly, comprising a mounting base 1 and an upper cross arm 2 and a lower cross arm 3 arranged on the mounting base 1;

[0032] The plane attaching assembly comprises a top block 4 arranged between the upper cross arm 2 and the lower cross arm 3 , and a blowing hole 41 is arranged on a side of the top block 4 facing away from the mounting seat 1 .

[0033] The side attachment component of the gluing mechanism of the embodiment of the present application includes a mounting base 1 and an upper cross arm 2 and a lower cross arm 3 installed on the mounting base 1. The top block 4 of the planar attachment component is arranged between the upper cross arm 2 and the lower cross arm 3. When the battery cell is pushed into the upper cross arm 2 and the lower cross arm 3, the end of the battery cell will first contact the tape arranged at the end of the upper cross arm 2 and the lower cross arm 3, and then contact and squeeze with the top block 4, to ensure that the tape can fit flatly and tightly to the end surface of the battery cell.

[0034] In addition, further, a blowing hole 41 is provided on the side of the top block 4 facing away from the mounting seat 1. The gas discharged from the blowing hole 41 can provide a force. Before the tape comes into contact with the top block, the tape can be blown toward the side where the battery cell is located, so that the tape is pre-attached to the end face of the battery cell to avoid slipping when the two ends of the tape are pulled, thereby reducing the risk of wrinkling the tape. The tape is not easy to deviate from the preset sticking position, thereby further improving the gluing effect of the end of the battery cell and ensuring the flatness and tightness of the tape on the battery cell.

[0035] It should be noted that, in the present embodiment, there are multiple blowing holes 41 on the top block 4 and they are distributed in an array. The gas discharged from the blowing holes 41 can act evenly on the surface of the tape, ensuring that the tape is pre-adhered to the end face of the battery cell under the premise of uniform tension. The tape is not easy to wrinkle and has better flatness. By squeezing the tape by the pressing block, it can be ensured that the tape is tightly adhered to the end face of the battery cell, and the tape will not be arched and peeled off under the action of its own stress due to being not tightly adhered.

[0036] In some alternative embodiments: See Figures 1 to 3 As shown, an embodiment of the present application provides a gluing mechanism, the planar attachment component of the gluing mechanism also includes a driving member 5 disposed on the mounting seat 1 and used to drive the top block 4 to reciprocate in the direction of the blowing hole 41 .

[0037] The driving member 5 of the adhesive bonding mechanism of the embodiment of the present application can drive the top block 4 to move toward the side where the battery cell is located. When the battery cell is pushed into the upper cross arm 2 and the lower cross arm 3, the end of the battery cell will first contact the tape arranged at the end of the upper cross arm 2 and the lower cross arm 3, and then contact and squeeze with the top block 4. The driving member 5 can smoothly push the battery cell out from between the upper cross arm 2 and the lower cross arm 3. In addition, the driving member 5 can also provide thrust to increase the squeezing force of the top block 4 on the tape to ensure that the tape is tightly adhered to the battery cell.

[0038] It should be noted that the driving member 5 in this embodiment is used to drive the top block 4 to perform linear displacement. Exemplarily, the driving member 5 can be an electric or pneumatic push rod, or a screw threadedly connected to the mounting seat 1 and the end of which is rotatably connected to the top block 4. Those skilled in the art can set or adjust it according to actual conditions.

[0039] In some alternative embodiments: See Figures 1 to 3 As shown, an embodiment of the present application provides a gluing mechanism, the planar attachment component of the gluing mechanism further includes a connecting member 6 connecting the driving member 5 and the top block 4.

[0040] The driving member 5 and the top block 4 of the glue-applying mechanism of the embodiment of the present application are connected by a connecting member 6, which can ensure the stability of the connection between the top block 4 and the driving member 5. Specifically, in this embodiment, the connecting member 6 includes a connecting plate 61 located between the upper cross arm 2 and the lower cross arm 3, and a connecting block 62 connected to the driving member 5 is installed on the connecting plate 61 by fasteners.

[0041] The end of the connecting block 62 away from the mounting seat 1 is fixed with a mounting plate 64 through an angle code 63, and the top block 4 is installed on the mounting plate 64 through fasteners. The end of the connecting block 62 close to the mounting seat 1 is installed with a limit block 65 through fasteners, which can limit the range of movement of the top block 4 and can stably support the top block 4 when the top block 4 is squeezed.

[0042] In some alternative embodiments: See Figures 1 to 3 As shown, an embodiment of the present application provides a gluing mechanism, in which a connecting member 6 is slidably connected to the upper cross arm 2 or the lower cross arm 3 .

[0043] The connecting member 6 of the adhesive bonding mechanism of the embodiment of the present application is slidably connected to the upper cross arm 2 or the lower cross arm 3, so as to guide and support the top block 4 connected to the connecting member 6. Specifically, in the present embodiment, a guide rail 66 arranged along the length direction thereof is installed on the lower cross arm 3, and a slider 67 cooperating with the guide rail 66 is installed on the connecting plate 61 of the connecting member 6, so as to guide and support the top block 4 in movement.

[0044] In some alternative embodiments: See Figures 1 to 3 As shown, an embodiment of the present application provides a gluing mechanism, and a limiting member 7 for limiting the range of movement of the connecting member 6 is installed on the upper cross arm 2 or the lower cross arm 3 of the gluing mechanism.

[0045] A limiting member 7 is installed on the upper cross arm 2 or the lower cross arm 3 of the glue-applying mechanism of the embodiment of the present application. The limiting member 7 is used to limit the range of movement of the connecting member 6, and further limit the range of movement of the top block 4. Specifically, in the present embodiment, the limiting member 7 is a T-shaped plate, which is installed on one side of the lower cross arm 3, and the two ends of the T-shaped plate extend to the front and rear sides of the connecting block 62.

[0046] In some alternative embodiments: See Figures 1 to 3 As shown, an embodiment of the present application provides a gluing mechanism, wherein the upper cross arm 2 and the lower cross arm 3 of the gluing mechanism are rotatably connected with brushes 8 for smoothing the tape, and the brushes 8 on both sides are oriented in opposite directions.

[0047] The upper cross arm 2 and the lower cross arm 3 of the gluing mechanism of the embodiment of the present application are all equipped with brushes 8, and the brushes 8 on the upper and lower sides are oriented opposite to each other. When the battery cell is pushed into the upper cross arm 2 and the lower cross arm 3, the gas discharged from the blowing hole 41 on the top block 4 blows the tape toward the side where the battery cell is located, so that the tape is pre-attached to the end face of the battery cell.

[0048] The battery cell continues to approach the top block 4 so that the two ends of the tape are in contact with the brushes 8. The brushes 8 on both sides squeeze the tape so that the two ends of the tape are close to the two sides of the battery cell, and the tape is smoothed and pasted to the two sides of the battery cell. At the same time, the movement is stopped until the battery cell is pushed in to fit with the top block 4 of the battery cell. After the battery cell is glued, the top block 4 pushes the battery cell out under the action of the driving member 5.

[0049] It should be noted that, in this embodiment, the brushes 8 on both sides are rotatably connected to the upper cross arm 2 and the lower cross arm 3 respectively, and the brushes 8 on both sides maintain relative initial positions to ensure that under the soft force of the brushes 8, the two ends of the tape can be attached to the upper and lower surfaces of the battery cell.

[0050] In the process of the battery cell being pushed out by the top block 4, the friction between the battery cell and the brush 8 can drive the brush 8 to rotate outward, so that the brush 8 rotates outward, avoiding the tape being scratched by the brush 8 and tilting up in the process of the battery cell being pushed out by the top block 4, and reducing the force of the brush 8 on the surface of the battery cell, making it easier for the top block 4 to push the battery cell.

[0051] In some alternative embodiments: See Figures 1 to 3 As shown, an embodiment of the present application provides a gluing mechanism, and a reset member for restoring the brushes 8 on both sides to their initial positions is provided on the upper cross arm 2 and the lower cross arm 3 of the gluing mechanism.

[0052] The upper cross arm 2 and the lower cross arm 3 of the gluing mechanism of the embodiment of the present application are provided with reset parts for resetting the brushes 8 on both sides to their initial positions. Specifically, when the battery cell is pushed out by the top block 4, the friction between the battery cell and the brush 8 can drive the brush 8 to rotate outward, so that the brush 8 rotates outward. When the battery cell is separated from the brush 8, the reset parts can reset the brushes 8 on both sides to their initial positions facing each other, thereby facilitating the start of the gluing action of the next battery cell.

[0053] Exemplarily, the reset member is a torsion spring, and the brushes 8 on both sides are rotatably connected to the upper cross arm 2 and the lower cross arm 3 respectively through the rotating shaft 81. A torsion spring (not shown in the figure) is connected between the upper cross arm 2 and the upper brush 8, and between the lower brush 8 of the lower cross arm 3. By reasonably designing the torsional force of the torsion spring, the battery cell can be pushed out by the top block 4, and the friction between the battery cell and the brush 8 can overcome the torsional force of the torsion spring and drive the brush 8 to rotate outward. When the battery cell is separated from the brush 8, the torsional force of the torsion spring can reset the brushes 8 on both sides to their initial positions facing each other.

[0054] In some other embodiments, the reset member can be a micro motor that drives the shaft 81 to rotate. The micro motor drives the shaft 81 to rotate, and the shaft 81 in turn drives the brush 8 to rotate. The brush 8 can be controlled to rotate outward to prevent the tape from being scraped by the brush 8 and lifted up when the battery cell is pushed out by the top block 4. After the top block 4 pushes the battery cell out, it can be controlled to rotate inwardly to the brush 8 to reset, so as to facilitate the start of the gluing action of the next battery cell.

[0055] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a gluing mechanism, and the ends of the upper cross arm 2 and the lower cross arm 3 of the gluing mechanism are both provided with mounting grooves 321 for accommodating the brush 8.

[0056] The ends of the upper cross arm 2 and the lower cross arm 3 of the glue sticking mechanism of the embodiment of the present application are both provided with mounting grooves 321 for accommodating the brush 8. Specifically, the brush 8 is rotatably connected in the mounting grooves 321 via the rotating shaft 81. The mounting grooves 321 can limit the rotation range of the brush 8, so as to facilitate keeping the brushes 8 on both sides in the relative initial positions. In the present embodiment, the end of the mounting groove 321 away from the mounting seat 1 is open, so that the brush 8 can be flipped outward to prevent the tape of the battery cell from being scraped by the brush 8 and tilted up when the battery cell is pushed out by the top block 4.

[0057] In some alternative embodiments: See Figures 1 to 4 As shown, the embodiment of the present application provides a gluing mechanism, and a limiting surface 322 for limiting the rotation angle of the brush 8 is arranged in the mounting groove 321 of the gluing mechanism.

[0058] The mounting groove 321 of the gluing mechanism of the embodiment of the present application is provided with a limiting surface 322 for limiting the rotation angle of the brush 8, so as to facilitate keeping the brushes 8 on both sides in the relative initial positions, or to allow the brushes 8 to flip outward to avoid. Specifically, in the present embodiment, the end of the mounting groove 321 away from the mounting seat 1 is opened, and the limiting surface 322 includes a horizontal limiting surface and a vertical limiting surface located in the mounting groove 321.

[0059] The horizontal limiting surface and the vertical limiting surface are perpendicular to each other, and the rotation range of the brush 8 can be limited to ninety degrees. When the brush 8 abuts against the vertical limiting surface, the brushes 8 on both sides face oppositely. When the brush 8 abuts against the horizontal limiting surface, the brushes 8 on both sides face outwards.

[0060] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a gluing mechanism, and the ends of the upper cross arm 2 and the lower cross arm 3 of the gluing mechanism away from the mounting seat 1 are both provided with suction holes 323 for adsorbing the tape.

[0061] The upper cross arm 2 and the lower cross arm 3 of the embodiment of the present application are both provided with suction holes 323 for adsorbing the tape at one end away from the mounting seat 1. The suction holes 323 can use negative pressure to adsorb the tape to keep the tape in a vertical position, making it convenient for the battery cell to approach the tape.

[0062] Specifically, the tape is adsorbed on the air intake holes 323 of the upper cross arm 2 and the lower cross arm 3. When the battery cell is pushed between the upper cross arm 2 and the lower cross arm 3 by the external mechanism, the bottom of the battery cell contacts the tape first. During this process, the air blowing holes 41 on the top block 4 can provide force to blow the tape toward the bottom side of the battery cell, so that the tape is pre-attached to the bottom of the battery cell.

[0063] When the battery cell is pushed in to fit with the top block 4, it stops moving. The tapes at both ends are attached to the upper and lower surfaces of the battery cell under the soft force of the brush 8. After the battery cell is glued, the top block 4 pushes the battery cell out and retracts under the action of the driving member 5, and the gluing action of the next battery cell begins.

[0064] In this embodiment, the upper cross arm 2 and the lower cross arm 3 are both separately arranged, including a side plate 31 and a fixing plate 32. The side plate 31 is fixedly connected to the mounting seat 1 by fasteners, and the mounting seat 1 is provided with oblong holes for installing fasteners, so as to facilitate adjustment of the installation distance between the two side plates 31. The side plate 31 and the fixing plate 32 are fixedly connected by fasteners, and the fixing plate 32 is conveniently separately processed with a mounting groove 321 and an air intake hole 323.
