[0032] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0033] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The existing wound battery cells are usually made of positive electrode sheets, separators and negative electrode sheets stacked and wound. After winding, glue needs to be applied to bundle the battery cells. At present, the battery cells need to be glued once to initially bundle the battery cells to maintain the winding shape of the battery cells, and then glue is applied twice to tighten and shape the battery cells to reduce damage to the battery cells when they are put into the shell.

[0035] In the prior art, the cell gluing device for secondary gluing of the cell mainly includes a jig for placing the cell, a gluing mechanism disposed above the jig, a pushing member disposed below the jig, and a first driving mechanism connected to the bottom of the pushing member. The first driving mechanism is used to drive the pushing member to move to lift the cell on the jig, so that the cell moves up to the gluing assembly for gluing. Positioning members for axial positioning of the cell are disposed on both sides of the jig in the horizontal direction, and the positioning members are connected to a second driving mechanism. Before gluing, the second driving mechanism can drive the positioning member to move so that the two positioning members are respectively in contact with the two end faces of the cell in the axial direction, thereby realizing the axial positioning of the cell. However, the cell conveying mechanism of this structure requires at least three driving mechanisms to complete the gluing operation, which is costly, and the cell needs to be positioned first and then lifted during gluing, so the gluing efficiency is low.

[0036] To this end, the utility model provides a battery core gluing device, which is mainly used to automatically glue the wound battery core to tighten and reshape the battery core. Figures 1 to 7 As shown, the battery cell gluing device includes a frame 1, on which are provided a jig 2 for placing the battery cell 100 to be glued, a connecting member 3, a gluing mechanism 4 and a transfer mechanism 5, the gluing mechanism 4 is arranged on one side of the jig 2 along a first direction (x direction in the figure), the transfer mechanism 5 includes a pushing member 51, a positioning member 52 and a first driving member 53, the pushing member 51 is arranged on the side of the jig 2 away from the gluing mechanism 4, and the positioning members 52 are slidably arranged on both sides of the jig 2 along the second direction (y direction in the figure), and the first direction and the second direction are arranged at an angle.

[0037] Among them, one of the connecting member 3 and the positioning member 52 is provided with an arc-shaped slide groove 6, and the two slide grooves 6 are convex inward in the relative directions between the two. The other of the connecting member 3 and the positioning member 52 is provided with a sliding portion 7. In this embodiment, the connecting member 3 is fixedly arranged on the frame 1, and the connecting member 3 is provided with the slide groove 6, and the positioning member 52 is provided with the sliding portion 7, and the sliding portion 7 is slidably connected in the slide groove 6. Moreover, the first driving member 53 is connected to the pushing member 51 and the two positioning members 52 through the bracket respectively. The first driving member 53 can drive the bracket to reciprocate along the first direction, so as to simultaneously drive the pushing member 51 and the two positioning members 52 to move along the first direction, so that the pushing member 51 lifts the battery cell 100 on the jig 2 and approaches the gluing mechanism 4 for gluing. At the same time, the positioning member 52 is slidably arranged on the bracket. During the movement of the positioning member 52 along the first direction, the connecting member 3 and the slide groove 6 arranged on the connecting member 3 remain stationary, and the sliding part 7 can move with the sliding part 7, so that the positioning member 52 moves along the first direction with the bracket, so that the sliding part 7 can move relative to the slide groove 6. Since the two slide grooves 6 are convex inwardly in the relative directions of the two, the two positioning members 52 can also move closer to or away from the jig 2 relative to the bracket along the second direction at the same time, so as to respectively abut against the opposite end surfaces of the battery cell 100 on the jig 2, thereby realizing the axial positioning of the battery cell 100.

[0038] The battery cell gluing device of the utility model can simultaneously drive the pushing member 51 and the positioning member 52 through a driving member, so as to reduce the number of driving mechanisms and reduce the manufacturing cost. Moreover, this design can also synchronously position the battery cell 100 when the pushing member 51 lifts the battery cell 100 and moves it, thereby reducing the gluing time and improving the gluing efficiency.

[0039] In this embodiment, the first direction is the vertical direction, the second direction is the horizontal direction, the glue sticking mechanism 4 is arranged above the jig 2, and two pushing members 51 spaced along the second direction are arranged below the jig 2. The two pushing members 51 are respectively used to lift the axial ends of the battery cell 100, and the positioning members 52 are arranged on both sides of the length direction of the jig 2, and the two positioning members 52 are both provided with a sliding portion 7, and the connecting member 3 is provided with a slide groove 6. The slide grooves 6 of the two connecting members 3 are partially protruded toward the jig 2 and form an arc-shaped guide groove. The sliding portion 7 and the slide groove 6 are connected one by one, so that the two positioning members 52 can move relative to or away from each other during the vertical movement.

[0040] Further, refer to Figures 1 to 3 , Figure 5 and Figure 7, one of the bracket and the positioning member 52 is provided with a first guide rail 8 extending along the second direction, and the other of the bracket and the positioning member 52 is provided with a first slider 9. For example, the bracket is provided with the first guide rail 8, and the positioning member 52 is provided with the first slider 9, and the first slider 9 is slidably connected to the first guide rail 8. By sliding with the first slider 9 and the first guide rail 8, the movement of the positioning member 52 can be limited to prevent the bracket from being offset when moving, thereby ensuring that the positioning member 52 always moves along the second direction.

[0041] In an optional embodiment, if Figure 2 Hezhi Figure 3 As shown, the bracket includes a first bracket 54 and a second bracket 55, the first driving member 53 is connected to the first bracket 54 and the second bracket 55 respectively, the positioning member 52 is arranged on the first bracket 54, and the pushing member 51 is arranged on the second bracket 55. Specifically, the first driving member 53 includes but is not limited to an electric cylinder and a pneumatic cylinder, the electric cylinder includes a motor and a screw rod, the motor is connected to the screw rod, the motor can drive the screw rod to rotate, so as to convert the rotary motion of the motor into a linear motion, the screw rod is connected to the first bracket 54, the screw rod can drive the first bracket 54 and the positioning member 52 to move in the first direction, and at the same time, the screw rod is connected to one end of the piston rod of the pneumatic cylinder, and the other end of the piston rod of the pneumatic cylinder is connected to the second bracket 55, the screw rod can drive the piston rod to move in the first direction and drive the second bracket 55 and the pushing member 51 to move in the first direction, so that the first driving member 53 drives the pushing member 51 and the positioning member 52 to move at the same time.

[0042] Further, refer to Figures 1 to 3 , Figure 5 and Figure 7 , one of the rack 1 and the first bracket 54 is provided with a second guide rail 10 extending in the first direction, and the other of the rack 1 and the first bracket 54 is provided with a second slider 11. For example, the first bracket 54 is provided with the second guide rail 10, the rack 1 is provided with a second slider 11 corresponding to the second guide rail 10, and the first slider 9 is slidably connected to the second guide rail 10. By sliding in cooperation with the second slider 11 and the second guide rail 10, the movement of the first bracket 54 can be limited to prevent the first bracket 54 from shaking and deflecting when moving, thereby improving the stability of the movement of the first bracket 54.

[0043] Furthermore, one of the rack 1 and the second bracket 55 is provided with a third guide rail 12 extending along the first direction, and the other of the rack 1 and the second bracket 55 is provided with a third slider 13. For example, the second bracket 55 is provided with the third guide rail 12, and the rack 1 is provided with a third slider 13 corresponding to the third guide rail 12, and the third slider 13 is slidably connected to the third guide rail 12. By sliding in cooperation with the third slider 13 and the third guide rail 12, the movement of the second bracket 55 can be limited to prevent the second bracket 55 from shaking and deflecting when moving, thereby improving the stability of the movement of the second bracket 55.

[0044] Of course, in other optional embodiments, the pusher 51 and the positioning member 52 may also be arranged on one bracket. Correspondingly, one of the rack 1 and the bracket is provided with a fourth rail extending along the first direction, and the other of the rack 1 and the bracket is provided with a fourth slider, which is slidably connected to the fourth rail. This design arranges the pusher 51 and the positioning member 52 on one bracket, so that only one rail and slider need to be provided for sliding cooperation to achieve smooth movement of the pusher 51 and the positioning member 52, which can reduce the number of parts of the battery cell glue sticking device and reduce costs.

[0045] Specifically, Figure 5 and Figure 6 As shown, at least one positioning member 52 includes a base 521, an abutting portion 522 and a sliding rod 523. The base 521 is arranged on the bracket, and a sliding hole is arranged on the base 521. The sliding rod 523 slides through the sliding hole along the second direction. The end of the sliding rod 523 close to the fixture 2 is connected to the abutting portion 522. An elastic member 56 is sleeved on the outer periphery of the sliding rod 523. The elastic member 56 can be a spring. The elastic member 56 abuts between the abutting portion 522 and the base 521. The elastic member 56 drives the abutting portion 522 to have a tendency to move away from the base 521. When the positioning member 52 abuts against the end face of the battery cell 100, the elastic force of the elastic member 56 can be used to make the abutting portion 522 press against the battery cell 100, and the elastic force of the elastic member 56 can be adjusted by sliding the sliding rod 523, thereby adjusting the abutting force of the abutting portion 522 against the battery cell 100 to prevent damage to the battery cell 100.

[0046] Furthermore, one end of the slide bar 523 away from the abutting portion 522 is screwed with a limiting nut, and the limiting nut abuts against a side surface of the base 521 away from the abutting portion 522 to limit the movement of the slide bar 523 and prevent the slide bar 523 from falling out of the slide hole.

[0047] Specifically, Figure 1 , Figure 2 and Figure 8As shown, the glue sticking mechanism 4 includes a rotatable glue storage wheel 46 and a glue sticking wheel 41. The glue storage wheel 46 is wound with a tape, and the tape has an adhesive surface and a non-adhesive surface that are relatively arranged. The glue sticking wheel 41 is adsorbed on the non-adhesive surface of the tape. The pushing member 51 can lift the battery cell 100 against the periphery of the glue sticking wheel 41. When the glue sticking wheel 41 rotates, the battery cell 100 can rotate synchronously with the glue sticking wheel 41 to achieve the purpose of sticking the tape to the periphery of the battery cell 100.

[0048] Optionally, combined Figures 2 to 5 The pushing member 51 is a roller. Two groups of rollers are arranged on the side of the fixture 2 away from the glue sticking mechanism 4. The two groups of rollers are arranged at intervals along the second direction. The two groups of rollers are respectively used to abut against the two ends of the side of the battery cell 100 away from the glue sticking mechanism 4. This design lifts the battery cell 100 through the smooth outer circumference of the roller, so that the battery cell 100 can rotate relative to the roller, so that the battery cell 100 can be glued with the rotation of the glue sticking wheel 41.

[0049] Preferably, each group of rollers includes two rollers arranged along a third direction (z direction in the figure), and the third direction is perpendicular to the first direction and the second direction respectively. In this embodiment, the third direction is the width direction of the fixture 2. The two side-by-side rollers can jointly support the limited battery cell 100, so that the battery cell 100 is located between the two side-by-side rollers along the third direction to prevent the battery cell 100 from rolling and falling when moving, which is conducive to improving the stability of the movement of the battery cell 100.

[0050] Since the battery cell 100 needs to rotate with the glue sticking wheel 41 during glue sticking, the positioning member 52 that is kept against the end surface of the battery cell 100 will affect the rotation of the battery cell 100 and interfere with the glue sticking of the battery cell 100. Figure 2 and Figure 4 Specifically, the slide groove 6 includes a first groove 61 and a second groove 62 connected at an angle, and the length direction of the first groove 61 extends close to the fixture 2 along the direction of the second groove 62, and the length direction of the second groove 62 extends away from the fixture 2. It can be understood that when the positioning member 52 moves toward the gluing mechanism 4 along the first direction, the sliding portion 7 can slide from the first groove 61 to the second groove 62, and during the sliding process in the first groove 61, the sliding portion 7 will gradually approach the jig 2 to drive the positioning member 52 to move gradually toward the jig 2 along the second direction. When the sliding portion 7 moves to the connection between the first groove 61 and the second groove 62, the positioning member 52 just abuts against the battery cell 100 to position the battery cell 100. After positioning, the sliding portion 7 moves into the second groove 62, and during the sliding process in the second groove 62, the sliding portion 7 gradually moves away from the jig 2 to drive the positioning member 52 away from the battery cell 100, so that when the battery cell 100 abuts against the gluing wheel 41, the battery cell 100 can rotate with the gluing wheel 41 for gluing, thereby avoiding the positioning member 52 affecting the gluing of the battery cell 100.

[0051] Specifically, continue to refer to Figure 1 and Figure 6 The glue sticking mechanism 4 also includes a cutter 42 and a second driving member 43. The cutter 42 is arranged on one side of the glue sticking wheel 41. The second driving member 43 is connected to the cutter 42. When the tape is wrapped around the battery cell 100 for one circle, the second driving member 43 can drive the cutter 42 to move close to the glue sticking wheel 41 to cut the tape.

[0052] Furthermore, the periphery of the rubber-applying wheel 41 is recessed with a rubber-cutting groove 411 for the cutter 42 to be inserted, and the second driving member 43 drives the cutter 42 to move and insert into the rubber-cutting groove 411. This design can not only avoid direct contact between the blade and the rubber-applying wheel 41 through the rubber-cutting groove 411 to prevent damage to the rubber-applying wheel 41, but also facilitate the blade to cut the tape.

[0053] Furthermore, the glue sticking mechanism 4 also includes a glue pressing wheel 44 and a third driving member 45. The glue pressing wheel 44 is arranged on one side of the glue sticking wheel 41 and is adjacent to the cutter 42. The third driving member 45 is connected to the glue pressing wheel 44. After the glue sticking is completed, the third driving member 45 can drive the glue pressing wheel 44 away from the glue sticking wheel 41 so that the glue sticking wheel 41 can rotate to replenish new tape. After the tape is replenished, the third driving member 45 can drive the glue pressing wheel 44 to move close to the glue sticking wheel 41 to press the tape so that the tape can be tightly attached to the outer periphery of the glue sticking wheel 41, thereby ensuring that the cutter 42 can smoothly cut the tape.
