[0003] A Chinese patent with the publication number CN114725480B discloses a battery cell gluing device, including a clamping mechanism, a conveying mechanism, and a gluing mechanism. The first clamping component clamps two opposite sides of the battery cell, and the second clamping component clamps two opposite surfaces of the battery cell, ensuring the firmness of the battery cell fixation. During the process of gluing the battery cell, the battery cell is not prone to shift, which is conducive to ensuring the gluing quality. However, this gluing device cannot ensure that the gluing position is stable and standard, reducing the misjudgment ratio of visual inspection and standardizing the normality of tape pasting. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies of the prior art and provide a square battery cell automatic gluing device. When the adsorption plate rotates driven by the rotary chain, it rises and falls. The adsorption plate adsorbs the back glue pad driven by the negative pressure component, and then one end of the release film is wound around the negative pressure tube through the glue tearing component. After the release film is separated from the back glue pad by the glue winding component, the adsorption plate drives the back glue pad to bond with the battery cell, improving the bonding efficiency and bonding accuracy, and replacing the phenomena of skew or unaesthetic pasting caused by manual gluing.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0038] Embodiment 1

[0039] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0040] like Figures 1 to 15 As shown, a square battery cell automatic glue sticking device includes a revolving chain 1, a guide rail 2 arranged outside the revolving chain 1, and a first conveyor belt 3 and a second conveyor belt 4 arranged on both sides of the guide rail 2. A guide component 5 and an adsorption component 6 driven by the guide component 5 are arranged above the revolving chain 1. The adsorption component 6 includes a fixed seat 61 slidably arranged on the guide rail 2 and an adsorption plate 62 slidably arranged on the fixed seat 61. A negative pressure component 7 is arranged above the revolving chain 1. A glue peeling component 8 is arranged between the revolving chain 1 and the second conveyor belt 4. The glue peeling component 8 includes a sliding seat 81 slidably arranged on the guide rail 2 and a rotatable plate 62 arranged on the sliding seat. A negative pressure tube 82 on 81, a toggle assembly 9 is arranged between the fixed seat 61 and the sliding seat 81, a glue rolling assembly 10 is arranged on the negative pressure tube 82, the guide assembly 5 is used to drive the adsorption plate 62 to adsorb the adhesive pad 11 on the first conveyor belt 3 and then bond it with the battery cell 12 on the second conveyor belt 4 under the cooperation of the negative pressure assembly 7, the glue peeling assembly 8 is used to make one end of the isolation film 13 on the adhesive pad 11 be wound around the negative pressure tube 82 under the cooperation of the toggle assembly 9, and the glue rolling assembly 10 is used to drive the isolation film 13 to separate the adhesive pad 11 from the adhesive pad 11 during the rotation of the negative pressure tube 82, wherein the adhesive pad 11 and the battery cell 12 are placed manually or by a robot.

[0041] It is worth mentioning that Figure 3 As shown, the guide assembly 5 includes a first track 51 fixedly arranged above the slewing chain 1, and a track groove 52 opened on the first track 51. The track groove 52 consists of a first descending section 53, a first ascending section 54, a second descending section 55 and a second ascending section 56.

[0042] In addition, if Figures 7 to 15As shown, the adsorption assembly 6 further includes a slider 63 slidably arranged on the fixed seat 61, a telescopic rod 64 fixedly arranged on the rotary chain 1, a fixed block 65 fixedly arranged on the telescopic rod 64, an adsorption tube 66 fixedly arranged on the adsorption plate 62, and a suction cup 67 fixedly arranged on the adsorption plate 62. The adsorption tube 66 is fixedly connected to the fixed block 65 and the slider 63. The suction cup 67 and the adsorption plate 62 are communicated with the adsorption tube 66. The bottom of the adsorption tube 66 is matched with the track groove 52. During use, after the adhesive pad 11 and the battery cell 12 are placed, when the first conveyor belt 3 and the second conveyor belt 4 are conveying, the rotary chain 1 drives the adsorption tube 66 and the adsorption plate 62 to rotate. When the adsorption tube 66 enters the first descending section 53, it drives the slider 63 to descend in the fixed seat 61, the telescopic rod 64 is compressed, and the adsorption plate 62 descends and gradually fits with the adhesive pad 11. Subsequently, under the action of the negative pressure assembly 7, the adhesive pad 11 is adsorbed. After adsorption, it enters the first ascending section 54 to drive the adhesive pad 11 to rise, and the isolation film 13 and the adhesive pad 11 are peeled off through the negative pressure tube 82. Subsequently, the adsorption tube 66 drives the peeled adhesive pad 11 into the second descending section 55. During this peeling process, the position of the battery cell 12 on the second conveyor belt 4 is always directly below the adhesive pad 11. Therefore, after entering the second descending section 55, the adsorption plate 62 drives the adhesive pad 11 to descend until it adheres to the battery cell 12. After the gluing is completed, the adsorption tube 66 enters the second ascending section 56 to rise and re-enters the first descending section 53 to prepare for adsorbing the next adhesive pad 11, improving the gluing efficiency and at the same time improving the gluing accuracy, and solving the problems of unsightly gluing and low efficiency caused by manual gluing.

[0043] It should be further noted that, as Figures 7 to 15 shown, the negative pressure assembly 7 includes a support rod 71, a second track 72 fixedly arranged on the support rod 71, a piston 73 slidably arranged in the adsorption tube 66, a piston rod 74 fixedly arranged on the piston 73, a hollow groove 75 opened on the track groove 52, and a connecting rod 76 fixedly arranged between the first track 51 and the second track 72. The second track 72 is composed of a first inclined section 77 and a second inclined section 78. The bottom of the piston rod 74 passes through the hollow groove 75 and is matched with the second track 72. During use, when the adsorption tube 66 slides out of the first descending section 53, the piston rod 74 enters the first inclined section 77 at the same time, driving the piston rod 74 and the piston 73 to slide away from the adhesive pad 11, generating suction force on the suction cup 67 to adsorb the adhesive pad 11. When the adsorption tube 66 slides out of the second descending section 55, the piston rod 74 enters the second inclined section 78 at the same time, driving the piston rod 74 and the piston 73 to slide towards the adhesive pad 11, canceling the suction force at the suction cup 67, separating the suction cup 67 from the adhesive pad 11, and the adhesive pad 11 adheres to the battery cell 12 and continues to be transported on the second conveyor belt 4 for the next process, greatly improving the automation degree of gluing.

[0044] It should be emphasized that, asFigure 10 and Figure 12 As shown, the glue peeling assembly 8 also includes a slide groove 83 opened on the guide rail 2 and a fixed sleeve 84 mounted on the negative pressure tube 82. The fixed sleeve 84 is fixedly arranged on the sliding seat 81. The sliding seat 81 cooperates with the slide groove 83 and a spring 85 is connected between the two. The fixed sleeve 84 is connected with a negative pressure device to make the negative pressure tube 66 generate suction. When in use, when the adsorption tube 66 enters the first rising section 54 to drive the adhesive pad 11 to rise to a set height, in the process of continuing to rotate, when passing through the negative pressure tube 82, the isolation film 13 and the adhesive pad 11 are peeled off through the negative pressure tube 82, thereby achieving the effect of automatic glue peeling.

[0045] It is worth mentioning that Figures 10 to 14 As shown, the toggle assembly 9 includes a fixed plate 91 fixedly arranged on the sliding seat 81, a toggle rod 92 rotatably arranged on the fixed plate 91, and an extension rod 93 fixedly arranged on the fixed seat 61. The toggle rod 92 is connected to the fixed plate 91 through a torsion spring, and the extension rod 93 cooperates with the toggle rod 92. When in use, when the adsorption plate 62 drives the adhesive pad 11 to slide out of the first rising section 54, the negative pressure tube 82 is located below one end of the adhesive pad 11, and the extension rod 93 conflicts with the toggle rod 92. Then the extension rod 93 drives the toggle rod 92 and the sliding seat 81 to slide in the slide groove 83, and the spring 85 is gradually compressed, and the negative pressure tube 82 moves synchronously with the adsorption plate 62 and the adhesive pad 11. At this time, the negative pressure The tube 82 and the adhesive pad 11 are relatively stationary, and the negative pressure tube 82 peels off one end of the isolation membrane 13 from the adhesive pad 11, so that one end of the isolation membrane 13 is wrapped around the negative pressure tube 82. When the sliding seat 81 slides to the end of the slide groove 83, the sliding seat 81 and the negative pressure tube 82 are restricted. At this time, the extension rod 93 drives the lever 92 to rotate downward until the extension rod 93 is disengaged from the lever 92. The lever 92 is reset under the action of the torsion spring, and at the same time, the spring 85 drives the fixed seat 81 and the negative pressure tube 82 to reset. In this way, the adsorption time of the negative pressure tube 82 and the isolation membrane 13 can be extended to ensure that the negative pressure tube 82 can peel off the isolation membrane 13 from the adhesive pad 11, instead of manually tearing the glue, to improve the effect.

[0046] Further, such as Figures 10 to 14As shown, the roll adhesive assembly 10 includes a gear 101 fixedly arranged on the negative pressure tube 82 and a rack 102 fixedly arranged on the slider 63. The gear 101 meshes with the rack 102. During use, when the extension rod 93 disengages from the lever 92 and the spring 85 pushes the sliding seat 81 and the negative pressure tube 82 to reset, the gear 101 meshes with the rack 102, driving the negative pressure tube 82 to rotate. At this time, the back adhesive pad 11 slides in the opposite direction to the negative pressure tube 82, causing the negative pressure tube 82 to continue winding the isolation film 13. After the sliding seat 81 resets and stops moving, since the back adhesive pad 11 is always in a sliding state, the negative pressure tube 82 completely peels off the isolation film 13 from the back adhesive pad 11 during rotation, enabling the isolation film 13 to be completely wound around the negative pressure tube 82. The isolation film 13 is removed from the negative pressure tube 82 manually or by a manipulator to prepare for the next adhesive tearing.

[0047] In addition, as Figure 10 shown, rubbers are provided on both the extension rod 93 and the lever 92 to reduce the friction between them and improve the service life.

[0048] As Figure 1 shown, a number of grooves 14 are formed on the first conveyor belt 3 and the grooves 14 cooperate with the back adhesive pad 11 to limit the back adhesive pad 11 through the grooves 14.

[0049] In addition, as Figure 1 shown, a number of limit blocks 15 are provided on the second conveyor belt 4 and the limit blocks 15 cooperate with the battery cell 12 to limit the battery cell 12 through the limit blocks 15 to ensure no deviation occurs during adhesive pasting.

[0050] Working process

[0051] After the adhesive pad 11 and the battery cell 12 are placed, the first conveyor belt 3 and the second conveyor belt 4 are conveyed simultaneously. The rotary chain 1 drives the suction tube 66 and the suction plate 62 to rotate. When the suction tube 66 enters the first descending section 53, it drives the slider 63 to descend in the fixed seat 61, the telescopic rod 64 is compressed, and the suction plate 62 descends and gradually fits with the adhesive pad 11. At the same time, the piston rod 74 enters the first inclined section 77, driving the piston rod 74 and the piston 73 to slide away from the adhesive pad 11, causing the suction cup 67 to generate suction force to adsorb the adhesive pad 11. After adsorption, it enters the first ascending section 54 to drive the adhesive pad 11 to rise. The negative pressure tube 82 is located below one end of the adhesive pad 11, and the extension rod 93 abuts against the lever 92. Subsequently, the extension rod 93 drives the lever 92 and the sliding seat 81 to slide in the chute 83, and the spring 85 is gradually compressed. The negative pressure tube 82 moves synchronously with the suction plate 62 and the adhesive pad 11. At this time, the negative pressure tube 82 and the adhesive pad 11 are relatively stationary. The negative pressure tube 82 peels off one end of the isolation film 13 from the adhesive pad 11, causing one end of the isolation film 13 to wind around the negative pressure tube 82. When the extension rod 93 disengages from the lever 92 and the spring 85 pushes the sliding seat 81 and the negative pressure tube 82 to reset, the gear 101 meshes with the rack 102, driving the negative pressure tube 82 to rotate. At this time, the adhesive pad 11 and the negative pressure tube 82 slide in opposite directions, causing the negative pressure tube 82 to continue winding the isolation film 13. When the sliding seat 81 resets and stops moving, since the adhesive pad 11 is always in a sliding state, the negative pressure tube 82 completely peels off the isolation film 13 from the adhesive pad 11 during rotation, causing the isolation film 13 to completely wind around the negative pressure tube 82. Subsequently, the suction tube 66 drives the peeled adhesive pad 11 into the second descending section 55, and the suction plate 62 drives the adhesive pad 11 to descend until it adheres to the battery cell 12. After the gluing is completed, the suction tube 66 enters the second ascending section 56 to rise and re-enters the first descending section 53 to prepare to adsorb the next adhesive pad 11, improving the gluing efficiency and the gluing accuracy at the same time, and solving the problems of unsightly gluing and low efficiency caused by manual gluing.
