[0002] The adhesive application mechanism in related technologies usually uses flipping or roller application to press the adhesive tape tightly onto the battery cell. This will squeeze the adhesive tape towards the center, causing the adhesive tape to separate from the battery cell and resulting in the adhesive tape bulging. Therefore, it is necessary to arrange personnel to manually fold the corners and apply adhesive from the center to both sides, which is labor-intensive. Utility Model Content

The adhesive wrapping module has a first surface on the side facing the suction module along the first direction, and a second surface on the side facing the suction module along the third direction. A boundary line is formed at the intersection of the first and second surfaces. The boundary line gradually moves away from the suction module from the center to both ends in the second direction. The first direction, the second direction, and the height direction of the adhesive application mechanism are perpendicular to each other. The suction module and the base frame are connected by a first driving module, which drives the suction module to move along the first direction; and / or the adhesive wrapping module and the base frame are connected by a second driving module, which drives the adhesive wrapping module to move along the first direction.

[0005] Beneficial effects: After the suction module sucks the battery cell with the adhesive paper, the suction module and the wrapping module can be driven to move close to each other by at least one of the first driving module and the second driving module, the wrapping module contacts the adhesive paper, and the adhesive paper on the side of the battery cell is folded to make part of the adhesive paper on the lower surface of the battery cell, and then the suction module and the wrapping module continue to move close to each other, and the wrapping module presses the adhesive paper on the lower surface of the battery cell to make the battery cell and the adhesive paper connect stably. By arranging the boundary line, the adhesive paper can first contact the boundary line at the center of the second direction, then the adhesive paper gradually contacts the boundary line from the center to the edge of the second direction, and then the adhesive paper can first adhere to the lower surface of the battery cell at the center of the second direction, and then the adhesive paper gradually adheres to the lower surface of the battery cell from the center to the edge of the second direction, so that the gas between the adhesive paper and the battery cell can be continuously squeezed out from the edge of the adhesive paper, avoiding the adhesive paper and the battery cell from being inflated due to the gas after being adhered, and the adhesive paper is not easy to wrinkle, and the adhesive effect between the adhesive paper and the battery cell is good.

By providing a support plate, the rubber coating plate can be supported to maintain its shape, preventing deformation or bending of the rubber coating plate under the action of gravity, and ensuring the reliability of the fit between the rubber coating plate and the battery cell with rubber paper.

[0014] In an alternative embodiment, the rubber coating mechanism further comprises a third driving module movably provided on the base frame in the third direction, the third driving module being connected to the rubber coating module for driving the rubber coating module to move in the third direction.

[0051] The embodiments of the present application will be described below in combination with Figures 1 to 12 The embodiments of the present application will be described below in combination with

[0052] According to the embodiments of the present application, a kind of smearing mechanism 1 is provided, smearing mechanism 1 includes two two opposite relatively first direction X, second direction Y and third direction Z, smearing mechanism 1 includes base frame 100, suction module 200 and wrap rubber module 300.

[0053] The suction module 200 is connected with the base frame 100 and is used for sucking the battery cell 2 with the adhesive paper 3. The wrapping module 300 is connected with the base frame 100, and the wrapping module 300 and the suction module 200 are arranged along the first direction X. The wrapping module 300 has a first surface 330 on the side of the wrapping module 300 facing the suction module 200 along the first direction X. The wrapping module 300 has a second surface 340 on the side of the wrapping module 300 facing the suction module 200 along the third direction Z. The first surface 330 is used for bending a part of the adhesive paper 3 to the lower side of the battery cell 2. The second surface 340 is used for pressing the part of the adhesive paper 3 to the lower surface of the battery cell 2. The intersection of the first surface 330 and the second surface 340 has a boundary line 301. The boundary line 301 gradually moves away from the suction module 200 from the center to the two ends along the second direction Y.

[0054] The suction module 200 and the base frame 100 are connected through the first driving module 400. The wrapping module 300 and the base frame 100 are fixedly connected. The first driving module 400 drives the suction module 200 to move along the first direction X.

[0055] In an embodiment not shown in the figure, the suction module 200 and the base frame 100 are fixedly connected. The wrapping module 300 and the base frame 100 are connected through the second driving module. The second driving module drives the wrapping module 300 to move along the first direction X.

[0056] In another embodiment not shown in the figure, the suction module 200 and the base frame 100 are connected through the first driving module 400. The wrapping module 300 and the base frame 100 are connected through the second driving module. The first driving module 400 drives the suction module 200 to move along the first direction X. The second driving module drives the wrapping module 300 to move along the first direction X.

[0057] For example, the first driving module 400 can include a driving motor or a cylinder or other devices with driving function. The second driving module can include a driving motor or a cylinder or other devices with driving function. The suction module 200 can include a vacuum suction cup and a vacuum pump. The lower surface of the vacuum suction cup is provided with a plurality of air suction holes. The side surface or the upper surface of the vacuum suction cup is provided with an air outlet. The air outlet is connected with the vacuum pump. When the lower surface of the vacuum suction cup contacts the battery cell 2 with the adhesive paper 3, the vacuum pump starts to work to draw the vacuum suction cup into a negative pressure state. The battery cell 2 with the adhesive paper 3 is adsorbed on the vacuum suction cup.

[0058] For example, the first driving module 400 can include a driving motor or a cylinder or other devices with driving function. The second driving module can include a driving motor or a cylinder or other devices with driving function. The suction module 200 can include a vacuum suction cup and a vacuum pump. The lower surface of the vacuum suction cup is provided with a plurality of air suction holes. The side surface or the upper surface of the vacuum suction cup is provided with an air outlet. The air outlet is connected with the vacuum pump. When the lower surface of the vacuum suction cup contacts the battery cell 2 with the adhesive paper 3, the vacuum pump starts to work to draw the vacuum suction cup into a negative pressure state. The battery cell 2 with the adhesive paper 3 is adsorbed on the vacuum suction cup. Figure 12As shown, after the suction module 200 sucks up the battery cell 2 with adhesive tape 3, the suction module 200 and the adhesive wrapping module 300 can approach each other under the drive of at least one of the first drive module 400 and the second drive module. The first surface 330 contacts the adhesive tape 3 and bends the adhesive tape 3 located on the side of the battery cell 2 so that a part of the adhesive tape 3 is located on the lower surface of the battery cell 2. Then the suction module 200 and the adhesive wrapping module 300 continue to approach each other. The second surface 340 presses the adhesive tape 3 located on the lower surface of the battery cell 2 onto the lower surface of the battery cell 2 so that the battery cell 2 and the adhesive tape 3 are stably connected.

[0059] By setting the boundary line 301, the adhesive tape 3 can first contact the boundary line 301 at the center of the second direction Y. Then, the adhesive tape 3 gradually contacts the boundary line 301 from the center to the edge of the second direction Y. The adhesive tape 3 first adheres to the battery cell 2 at the center of the second direction Y. Then, the adhesive tape 3 gradually adheres to the battery cell 2 from the center to the edge of the second direction Y. This can continuously squeeze out the air between the adhesive tape 3 and the battery cell 2 from the edge of the adhesive tape 3, avoiding the presence of air and bulging after the adhesive tape 3 and the battery cell 2 are adhered. In addition, the adhesive tape 3 is not easy to wrinkle. The adhesion effect between the adhesive tape 3 and the battery cell 2 is good. It does not require manual operation, the adhesive application speed is fast, the consistency is good, which is conducive to the automation of the whole line and reduces costs.

[0060] like Figure 3 As shown, in the technical solution of this embodiment, the boundary line 301 includes a straight line 3011 and two inclined lines 3012. Both inclined lines 3012 are connected to the straight line 3011, and the two inclined lines 3012 are located on opposite sides of the straight line 3011 in the second direction Y.

[0061] In an embodiment not shown, the boundary line 301 may also be constructed as an arc.

[0062] In this way, the adhesive wrapping module 300 and the adhesive tape 3 make contact through an arc or through a straight line 3011. The contact area between the adhesive wrapping module 300 and the adhesive tape 3 is large, which can avoid pressure concentration on the adhesive tape 3 and reduce the probability of damage to the adhesive tape 3.

[0063] like Figure 3 As shown, in the technical solution of this embodiment, the first surface 330 is provided with a guide slope 302 and a plane 303. The guide slope 302 is connected between the boundary line 301 and the plane 303 along the first direction X. The guide slope 302 is gradually inclined downward in the direction closer to the suction module 200, that is, the guide slope 302 is inclined in the third direction Z relative to the plane 303 in the direction away from the suction module 200.

[0064] In this way, the guide slope 302 can make the bending of the adhesive tape 3 smoother, so as to improve the contact effect between the adhesive tape 3 and the battery cell 2.

[0065] As shown in the technical scheme of the embodiment, the two rubber wrapping modules 300 are located on opposite sides of the suction module 200 in the first direction X. Figure 1

[0066] In this way, the two rubber wrapping modules 300 can press opposite sides of the rubber paper 3 in the first direction X, that is, one rubber wrapping module 300 presses one side of the rubber paper 3 in the first direction X, and the other rubber wrapping module 300 presses the other side of the rubber paper 3 in the first direction X, thereby improving the rubber wrapping efficiency of the battery cell 2 with rubber paper.

[0067] As shown in the technical scheme of the embodiment, the two rubber wrapping modules 300 are located on opposite sides of the suction module 200 in the first direction X. Figure 3

[0068] For example, the rubber wrapping plate 310 can be made of materials such as silicone, rubber, polyurethane (PU), polypropylene (PP), etc., and the support plate 320 can be made of hard plastic, metal, etc.

[0069] In addition, the support plate 320 includes a support body 321 and two mounting ears 322. The support body 321 is connected to the rubber wrapping plate 310, and the two mounting ears 322 are separately arranged on opposite sides of the support body 321 in the second direction Y. The upper surface of the mounting ear 322 is lower than the upper surface of the support body 321. The rubber wrapping plate 310 can be glued to the support body 321, and the glue may overflow the edge of the support body 321, or the rubber wrapping plate 310 can be directly formed on the support body 321, and the rubber wrapping plate 310 may overflow the edge of the support body 321. In this way, the rubber wrapping plate 310 and the support body 321 have less effect on the mounting ear 322 after being connected, thereby ensuring the convenience of disassembly between the mounting ear 322 and the base frame 100.

[0070] By setting the rubber wrapping plate 310 to be elastically deformable, when the battery cell 2 with rubber paper 3 is pressed onto the rubber wrapping plate 310, the rubber wrapping plate 310 can be elastically deformed to apply elastic force to the rubber paper 3, thereby adapting to the shape of the battery cell with rubber paper and improving the connection strength between the rubber paper 3 and the battery cell 2. By setting the support plate 320, the rubber wrapping plate 310 can be supported to maintain its own shape, thereby avoiding deformation or bending of the rubber wrapping plate 310 under the action of gravity and ensuring the reliability of the fit between the rubber wrapping plate 310 and the battery cell 2 with rubber paper 3.

[0071] ​​In an embodiment not shown, the glue applying mechanism 1 further comprises a third driving module, the third driving module is movably connected with the base frame 100 along the third direction Z, the third driving module is connected with the glue wrapping module 300, and is used to drive the glue wrapping module 300 to move along the third direction Z.

[0072] For example, the third driving module can comprise a driving motor or a cylinder or other device having a driving function.

[0073] By arranging the third driving module, when the adhesive tape 3 needs to be pressed, the third driving module drives the glue wrapping module 300 to move upward, the glue wrapping module 300 contacts the battery cell 2 with the adhesive tape, so as to press the adhesive tape 3 on the battery cell 2, and ensure the connection strength between the battery cell 2 and the adhesive tape 3. After the adhesive tape 3 is pressed, the third driving module drives the glue wrapping module 300 to move downward, the glue wrapping module 300 is separated from the battery cell 2 with the adhesive tape 3, so as to avoid the friction between the glue wrapping module 300 and the battery cell 2 with the adhesive tape 3 when the battery cell with the adhesive tape is displaced relative to the glue wrapping module 300 along the first direction X, prevent the adhesive tape 3 from being separated from the battery cell 2 due to the friction between the glue wrapping module 300 and the battery cell with the adhesive tape, reduce the friction, and also reduce the damage probability of the battery cell with the adhesive tape, and prolong the service life of the battery cell with the adhesive tape.

[0074] As shown in Figure 4 In the technical scheme of the embodiment, the base frame 100 comprises a bearing plate 110, a first bushing 120, a first guide shaft 130, a mounting plate 140, and a first elastic member 150.

[0075] The first bushing 120 is connected with the bearing plate 110, the first guide shaft 130 is slidably arranged in the first bushing 120, the first guide shaft 130 extends along the third direction Z, the mounting plate 140 is connected with the first guide shaft 130 and is located on the side of the bearing plate 110 facing the suction module 200 along the third direction Z, the glue wrapping module 300 is arranged on the side of the mounting plate 140 facing the suction module 200 along the third direction Z, the first elastic member 150 is clamped between the bearing plate 110 and the mounting plate 140, and the first elastic member 150 is elastically deformed.

[0076] For example, the first bushing 120 comprises a first base 121 and a first shaft sleeve 122, the first base 121 is located on the side of the bearing plate 110 away from the mounting plate 140, the first base 121 is fixedly connected with the bearing plate 110, and the first base 121 and the bearing plate 110 can be fixedly connected by a threaded fastener such as a bolt, the first shaft sleeve 122 is connected with the first base 121 and penetrates the bearing plate 110, the first guide shaft 130 penetrates the first base 121 and the first shaft sleeve 122, and is slidable relative to the first base 121 and the first shaft sleeve 122.

[0077] The base frame 100 further comprises a positioning shaft 160 penetrating through the bearing plate 110 and connected with the mounting plate 140, the first elastic member 150 is a spring, and the first elastic member 150 is sleeved on the positioning shaft 160, so that the first elastic member 150 cannot be bent to effectively support the mounting plate 140.

[0078] The mounting plate 140 is connected with the support plate 320 of the rubber wrapping module 300, and the mounting plate 140 and the support plate 320 can be fixedly connected through a threaded fastener such as a bolt.

[0079] By arranging the first bushing 120, the first guide shaft 130 and the first elastic member 150, the relative position between the mounting plate 140 and the bearing plate 110 can be fixed, so that the bearing plate 110 bears the mounting plate 140 and the rubber wrapping module 300, and the rubber wrapping module 300 is prevented from being separated from the base frame 100, and the mounting plate 140 can move along the height direction of the rubber coating mechanism 1 relative to the bearing plate 110. The first elastic member 150 is clamped by the mounting plate 140 and the bearing plate 110, the elastic force of the first elastic member 150 pushes the mounting plate 140 to move upward, when the battery cell 2 with the adhesive tape 3 presses the rubber wrapping module 300, the rubber wrapping module 300 drives the mounting plate 140 to move downward, the elastic force of the first elastic member 150 increases to continuously exert an upward reaction force on the mounting plate 140, so that the rubber wrapping module 300 and the battery cell 2 with the adhesive tape 3 can be tightly attached, and the elastic deformation of the first elastic member 150 can play a role of energy storage of suction force, so that the battery cell 2 with the adhesive tape 3 is prevented from being damaged due to excessive pressure.

[0085] The working process of the glue applying mechanism 1 will be described below by way of example:

[0086] Firstly, the fourth driving module 500 drives the suction module 200 to move downward, and the suction module 200 sucks the battery cell 2 with the adhesive tape 3, and the relative positions between the battery cell 2 with the adhesive tape 3 and the suction module 200 are fixed;

[0088] Finally, as shown in Figure 11 the first side bonding segment 32 contacts the first glue folding module 600, the first glue folding module 600 bends the first side bonding segment 32 downward, the first side bonding segment 32 contacts one side of the battery cell 2 in the first direction X, the second side bonding segment 33 contacts the second glue folding module 700, the second glue folding module 700 bends the second side bonding segment 33 downward, and the second side bonding segment 33 contacts the other side of the battery cell 2 in the first direction X.

[0089] By setting the fourth driving module 500, the first glue folding module 600 and the second glue folding module 700, the adhesive paper 3 can be folded on both sides in the first direction X at the same time, realizing the function of double folding edges, and the adhesive paper 3 is not prone to wrinkles, thereby realizing the function of imitating manual glue smearing, achieving the effects of automatic production and cost reduction and efficiency increase.

[0090] As shown in Figure 5 and Figure 6 In the technical scheme of the embodiment, the first glue folding module 600 comprises a positioning plate 610, a second guide shaft 620, a second bushing 630, a glue folding plate 640, a limiting piece 650 and a second elastic piece 660.

[0091] The positioning plate 610 is connected with the base frame 100, the second guide shaft 620 is connected with the positioning plate 610, the second guide shaft 620 extends along the first direction X, the second bushing 630 is located on the side of the positioning plate 610 away from the suction module 200, and the second bushing 630 is slidably sleeved on the second guide shaft 620. The glue folding plate 640 comprises a guide section 641, the guide section 641 is located on the side of the positioning plate 610 away from the suction module 200, and the guide section 641 is connected with the second bushing 630. The limiting piece 650 is connected with the second guide shaft 620 and located on the side of the guide section 641 away from the suction module 200, the second elastic piece 660 is clamped between the limiting piece 650 and the guide section 641, and the second elastic piece 660 is elastically deformed.

[0092] Specifically, the second bushing 630 comprises a second base 631 and a second shaft sleeve 632, the second base 631 is connected with the guide section 641, the second base 631 and the guide section 641 can be fixedly connected by a threaded fastener such as a bolt, the second base 631 is located between the guide section 641 and the positioning plate 610, and the second shaft sleeve 632 is provided through the guide section 641. Moreover, the glue folding plate 640 further comprises a connecting section 643 and a glue folding section 642, the glue folding section 642 is located on the lower side of the positioning plate 610 and is spaced apart from the positioning plate 610, and the connecting section 643 is connected to the lower edge of the guide section 641 and the upper edge of the glue folding section 642.

[0093] The size of the battery cell 2 in the first direction X can be greater than the distance between the lower end of the glue folding plate 640 of the first glue folding module 600 and the lower end of the second glue folding module 700, so that when the battery cell 2 with the adhesive paper 3 moves upward, the battery cell 2 with the adhesive paper 3 is respectively stopped by the glue folding plate 640 of the first glue folding module 600 and the second glue folding module 700 on the opposite sides in the first direction X (i.e., the first side bonding section 32 is located between the battery cell 2 and the glue folding plate 640, and the second side bonding section 33 is located between the battery cell 2 and the second glue folding module 700), the battery cell 2 with the adhesive paper 3 provides a pushing force to the glue folding plate 640 in the direction of the limiting member 650, the glue folding plate 640 drives the second bushing 630 to slide along the second guide shaft 620, the distance between the glue folding plate 640 and the limiting member 650 gradually decreases, the second elastic member 660 is compressed to increase the size, and the elastic force of the second elastic member 660 pushing the glue folding plate 640 to compress the battery cell with the adhesive paper 3 is greater, so that the connection between the battery cell 2 with the adhesive paper 3 and the adhesive paper 3 is tight, which is beneficial to expel the air between the battery cell 2 and the adhesive paper 3.

[0094] By arranging the second guide shaft 620 and the second bushing 630, the positioning between the positioning plate 610, the glue folding plate 640, the limiting member 650 and the second elastic member 660 can be achieved, the moving resistance of the glue folding plate 640 can be reduced, the moving direction of the glue folding plate 640 can be limited, and the deflection of the glue folding plate 640 can be avoided. By arranging the second elastic member 660, an elastic force of the second elastic member 660 pushing the glue folding plate 640 to move in the direction of the battery cell 2 with the adhesive paper 3 can be applied, so that the connection between the battery cell 2 with the adhesive paper 3 and the adhesive paper 3 is tight, which is beneficial to expel the air between the battery cell 2 and the adhesive paper 3.

[0095] For example, the second glue folding module 700 can be an integral member connected with the base frame 100, so as to simplify the structure of the second glue folding module 700 and reduce the processing difficulty; or the structure of the second glue folding module 700 can be the same as that of the first glue folding module 600, so as to increase the clamping force of the first glue folding module 600 and the second glue folding module 700 on the battery cell 2 with the adhesive paper 3 and more effectively stabilize the connection between the battery cell 2 and the adhesive paper 3.

[0096] As shown in FIGS. 1, 2 and 3, the first glue folding module 600 and the second glue folding module 700 are arranged on the base frame 100, and the first glue folding module 600 and the second glue folding module 700 are arranged in the first direction X. Figure 5 and Figure 7 As shown in FIGS. 1, 2 and 3, the first glue folding module 600 and the second glue folding module 700 are arranged on the base frame 100, and the first glue folding module 600 and the second glue folding module 700 are arranged in the first direction X.

[0097] In an embodiment not shown, the lower end of the second folding module 700 may also be provided with a second guide surface. The second guide surface gradually tilts upward in the direction close to the suction module 200. At this time, the distance between the lower edge of the second guide surface and the first folding module 600 is greater than the size of the battery cell 2 with adhesive paper 3 in the first direction X, and the distance between the upper edge of the second guide surface and the first folding module 600 is less than the size of the battery cell 2 with adhesive paper 3 in the first direction X.

[0098] In another embodiment not shown, the lower end of the first adhesive folding module 600 is provided with a first guide surface 601, and the lower end of the second adhesive folding module 700 is provided with a second guide surface. In this case, the distance between the lower edge of the first guide surface 601 and the lower edge of the second guide surface is greater than the size of the battery cell 2 with adhesive paper 3 in the first direction X, and the distance between the upper edge of the first guide surface 601 and the upper edge of the second guide surface is less than the size of the battery cell 2 with adhesive paper 3 in the first direction X.

[0099] By setting at least one of the first guide surface 601 and the second guide surface, the distance between the first folding module 600 and the second folding module 700 gradually increases from bottom to top. Therefore, when the battery cell 2 with adhesive paper 3 moves upward, the battery cell 2 with adhesive paper 3 can be easily inserted between the first guide surface 601 and the second guide surface. Then, as the battery cell 2 with adhesive paper 3 gradually rises, the battery cell with adhesive paper pushes the folding plate 640 to move towards the limiting member 650, which facilitates moving the battery cell 2 with adhesive paper 3 to the first folding module 600 and the second folding module 700.
