[0002] With the development of technology, new energy power batteries are being used more and more widely. As a core component of batteries, the production quality of battery cells is closely related to the quality of batteries. In the production process of battery cells, the surface of the battery cells except the top cover needs to be wrapped with an insulating film, and the quality of the wrapped insulating film has an important impact on the performance and safety of the battery cells.

DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0024] like Figure 1 As shown, in a preferred embodiment, the corner gluing device of the present invention includes a fixing seat 1, a tape unwinding mechanism 2 for unwinding the tape, a tape cutting mechanism 3 for horizontally tensioning and cutting the tape, a gluing mechanism 4 for adsorbing the tape and sticking the tape to the corner of the product, and a shaping mechanism 5 for folding and flattening the tape stuck to the corner of the product.

[0025] Among them, the tape unwinding mechanism 2 is arranged on the fixed seat 1. In this embodiment, the tape unwinding mechanism 2 includes two symmetrically arranged unwinding units 21, a gap is formed between the two unwinding units 21, and the tape discharge ports of the two unwinding units 21 are opposite and both face the gap.

[0026] Please refer to Figure 2 The tape cutting mechanism 3 includes a clamping unit 31 for clamping the two ends of the tape and a cutter 32 for cutting the tape. The clamping unit 31 includes a first clamping member 33 and a second clamping member 34. The first clamping member 33 is arranged on the fixed seat 1 near the discharge port of the tape unwinding mechanism 2, and the second clamping member 34 is movably arranged on the side of the first clamping member 33 away from the tape unwinding mechanism 2. The second clamping member 34 can clamp the end of the tape and move horizontally in a direction away from the first clamping member 33 under the drive of the cylinder, so as to pull out and tension the tape. The cutter 32 is vertically arranged between the first clamping member 33 and the second clamping member 34, and the cutter 32 can move vertically under the drive of the cylinder to cut the tape.

[0027] The tape cutting mechanism 3 can realize automatic pulling out and tensioning of the tape, as well as automatic cutting of the tape, thereby effectively improving the efficiency of adhesive application.

[0028] Please refer to Figure 3The glue sticking mechanism 4 includes a glue sticking driving unit 41, a seat body 42, and a glue sticking piece 43. The glue sticking driving unit 41 is arranged on the fixed seat 1, located in the gap between the two unwinding units 21, the seat body 42 is slidably connected to the glue sticking driving unit 41, and the glue sticking piece 43 is symmetrically arranged on both sides of the seat body 42.

[0029] The adhesive member 43 includes a first patch 44 and a second patch 45 arranged in parallel, and the first patch 44 and the second patch 45 are used to absorb the two ends of the adhesive tape respectively. The first patch 44 and the second patch 45 are both rectangular parallelepiped, and the first patch 44 is arranged on the outside of the second patch 45, and the sides of the two are against or close to each other, and the surfaces of the two facing the front end are provided with air holes, and the air holes are used to absorb the adhesive tape on the front end surfaces of the two. Among them, the first patch 44 is fixedly connected to the seat body 42, and the second patch 45 is elastically connected to the seat body 42, so that the second patch 45 can slide relative to the first patch 44. Specifically, the rear end of the second patch 45 is provided with an elastic member 46, and the elastic member 46 can make the second patch 45 move relative to the first patch 45 along the extension direction of the adhesive driving unit 41. It should be noted that the distance between the two first patches 45 is slightly smaller than the width of the product, and the distance between the two second patches 45 matches the width of the product.

[0030] The gluing mechanism 4 can automatically stick the tape on the bottom surface of the product and bend the tape into an L shape so that the tape fits the bottom surface and both side surfaces of the product, thereby improving the gluing accuracy and efficiency.

[0031] Please refer to Figure 4 and Figure 5 The shaping mechanism 5 includes a shaping block 51 and a shaping drive unit 52. The shaping blocks 51 are arranged opposite to each other, and include two first shaping bosses 53 in the form of long strips arranged at the front side, and two second shaping bosses 54 in the form of long strips arranged at the rear side. The first shaping bosses 53 and the second shaping bosses 54 are parallel, and both extend in the horizontal direction. The length of the second shaping bosses 54 is greater than that of the first shaping bosses 53. The two first shaping bosses 53 are opposed to each other up and down, and the two second shaping bosses 54 are opposed to each other up and down. A right angle edge matching the product surface is formed between the two first shaping bosses 53 and between the two second shaping bosses 54.

[0032] The shaping drive unit 52 includes a first drive member 55, a second drive member 57, and a third drive member 56, all of which are arranged on the fixed seat 1. The first drive member 55 is used to drive the shaping block 51 to move toward the product, so that the shaping block 51 is close to the corner of the product. The second drive member 57 is used to drive the shaping block 51 to move toward each other, so that the first shaping boss 53 of the shaping block 51 slides over the upper surface and the lower surface of the product from both sides of the product. The third drive member 56 is used to drive the shaping block 51 to slightly move forward along the moving direction of the first drive member 55, so that the second shaping boss 54 slides forward from the rear side of the product over the upper surface and the lower surface of the product.

[0033] The shaping mechanism 5 can fold and flatten the adhesive tape so that it can be firmly attached to the surface of the product, thereby preventing the insulating film from shifting or loosening due to the loosening of the adhesive tape, thereby improving the quality of product film attachment.

[0034] The working principle of the corner gluing device is as follows: the tape unwinding mechanism 2 unwinds the tape to the discharge port, the first clamping member 33 clamps the end of the tape, and moves horizontally in the direction away from the discharge port under the drive of the cylinder, thereby pulling the tape out, at this time the second clamping member 34 clamps the end of the tape close to the discharge port, and at the same time the gluing mechanism 4 sucks the tape, and the cutter 32 moves vertically to cut the tape. Then the gluing member 43 drives the tape to move toward the product, the first sticking block 44 contacts the bottom surface of the product near the corner, and under the action of the elastic member 46, it presses against the bottom surface of the product and sticks the tape at the contact position, at this time the second sticking block 45 continues to move forward from both sides of the product and slides over the two side surfaces of the product, thereby bending the tape into an "L" shape, so that the tape is stuck to the two side surfaces of the product. Then the glue sticking member 43 is reset, the first driving member 55 drives the shaping block 51 to move to both sides of the product, and the second driving member 57 drives the shaping block 51 to move toward each other, so that the first shaping boss 53 slides over the upper and lower surfaces of the product from both sides of the product, respectively, so that the tapes on both sides are closely attached to the upper and lower surfaces of the product, and the third driving member 56 drives the shaping block 51 to move forward slightly, so that the second shaping boss 54 slides forward from the rear side of the product over the upper and lower surfaces of the product, so that the tapes on the bottom are close to the upper and lower surfaces of the product, and finally the shaping block 51 is reset to complete the glue sticking.

[0035] To sum up, the corner gluing device of the present invention realizes automatic gluing of product corners, improves the efficiency of product film pasting, and at the same time can make the tape adhere flatly and firmly to the surface of the insulating film, avoiding the displacement or loosening of the insulating film caused by the loose tape, thereby improving the quality of product film pasting.
