[0002] During the production process of batteries, it is necessary to apply adhesive tape to various parts of the battery. Therefore, a gluing mechanism is indispensable in the automated production process of batteries. Existing gluing mechanisms are usually only provided with an adsorption unit for taking adhesive tape, and the adsorption unit can often only adsorb and apply to the center area of ​​the adhesive tape, and cannot take into account the application of the edge area of ​​the adhesive tape, especially when attaching some adhesive tapes with bent structures on the sides, it is impossible to ensure that the side areas of the adhesive tape are also applied in place. For example, during the production process of wearable soft-pack lithium batteries, it is necessary to attach fireproof adhesive tape to the battery shell, and the fireproof adhesive tape often has a bending structure on the side. The existing gluing mechanism cannot achieve the application of the bent parts of the side of the adhesive tape in place, so it is easy to cause the side of the adhesive tape to be not attached properly and affect the fire prevention effect, thereby affecting the quality of the product.

[0036] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] refer to Figures 1 to 3 The utility model provides a gluing mechanism for a lithium battery shell. The gluing mechanism 1 includes a first driving module 11 and a gluing module 12 connected to the driving end of the first driving module 11. In some embodiments, the first driving module 11 is a mechanical arm that can drive the gluing module 12 to move between various workstations. Specifically, the gluing module 12 includes an adsorption unit 121 and an expansion unit 122 located at the periphery of the adsorption unit 121. The adsorption unit 121 is used to adsorb the adhesive tape body, and the expansion unit 122 is used to push the side of the adhesive tape against the inner wall of the battery shell.

[0040] In some embodiments, the adhesive tape body is a planar structure, and the side of the adhesive tape is bent so that it forms a certain angle with the adhesive tape body. It is understandable that in the initial state, the expansion unit 122 is close to the outer wall of the adsorption unit 121, and the bottom of the expansion unit 122 is in the same plane as the bottom of the adsorption unit 121, so that when the adsorption unit 121 adsorbs the adhesive tape, the bottom of the expansion unit 122 can also be pressed against the adhesive tape; when applying the adhesive tape, the adsorption unit 121 first attaches the adhesive tape to the bottom wall of the battery shell, and then the expansion unit 122 expands outward, and the expansion unit 122 first moves against the edge of the adhesive tape body, and then pushes the bent side of the adhesive tape against the inner wall of the battery shell to complete the attachment of the adhesive tape.

[0041] The adhesive tape is attached to the center area of ​​the tape body through the adsorption unit 121, and the adhesive tape is attached to the edge area of ​​the tape body and the bent side of the tape through the expansion unit 122, thereby achieving all-round application of the tape, improving the fit between the tape and the battery shell, and effectively improving the production quality of battery products.

[0042] As a further optimization, the driving end of the first driving module 11 is connected to the mounting plate 111, and the adsorption unit 121 and the expansion unit 122 are both arranged on the mounting plate 111. The expansion unit 122 includes a slide rail 1221 arranged on the mounting plate 111 in the horizontal direction, and the first expansion block 1222 and the second expansion block 1223 are slidably connected to the slide rail 1221, and a spring 1224 is connected between the first expansion block 1222 and the second expansion block 1223 in the horizontal direction, and the first expansion block 1222 and the second expansion block 1223 are respectively located on opposite sides of the adsorption unit 121. In the initial state, the first expansion block 1222 and the second expansion block 1223 are close to the outer wall of the adsorption unit 121, and the bottoms of the first expansion block 1222 and the second expansion block 1223 are both in the same plane as the bottom of the adsorption unit 121. The expansion unit 122 also includes a transmission component 1225 for transmitting the first expansion block 1222 and the second expansion block 1223 to move closer to or away from each other.

[0043] As one embodiment, the transmission assembly 1225 includes a transmission block 1226 that can move in a vertical direction. The movement of the transmission block 1226 is driven by a lifting drive cylinder. The transmission block 1226 is located above the first expansion block 1222 and the second expansion block 1223. A first transmission part 1227 and a second transmission part 1228 are formed at the end of the transmission block 1226. The first transmission part 1227 abuts against the first expansion block 1222, and the second transmission part 1228 abuts against the second expansion block 1223.

[0044] It can be understood that, in the natural state, due to the pulling and limiting effect of the spring 1224, the relative position between the first expansion block 1222 and the second expansion block 1223 is fixed. When the transmission block 1226 moves downward, the first transmission part 1227 and the first expansion block 1222 generate relative movement, and the second transmission part 1228 and the second expansion block 1223 generate relative movement, thereby pushing the first expansion block 1222 and the second expansion block 1223 to move closer to or away from each other. As one embodiment, when the transmission block 1226 moves downward, the first transmission part 1227 pushes the first expansion block 1222 to move in the direction of the second expansion block 1223, and the second transmission part 1228 moves the second expansion block 1223 in the direction of the first expansion block 1222, thereby making the first expansion block 1222 and the second expansion block 1223 move closer to each other. It can be understood that when the transmission block 1226 moves downward to the lowest position, the spring 1224 is squeezed, and the first expansion block 1222 and the second expansion block 1223 are located close to the adsorption unit 121. At this time, the glue module 12 is in a state before gluing; when the transmission block 1226 starts to move upward, the first expansion block 1222 and the second expansion block 1223 gradually move away from each other under the elastic force of the spring 1224, thereby realizing the gluing operation on the side area of ​​the adhesive tape.

[0045] As a further optimization, a first roller 1229 is provided at the abutting portion of the first transmission part 1227 and the first expansion block 1222, and a second roller 1220 is provided at the abutting portion of the second transmission part 1228 and the second expansion block 1223. The first roller 1229 can reduce the friction force when the first transmission part 1227 and the first expansion block 1222 move relative to each other, and the second roller 1220 can reduce the friction force when the second transmission part 1228 and the second expansion block 1223 move relative to each other, thereby making the transmission process of the transmission block 1226 smoother, which is conducive to improving the operation production efficiency.

[0046] Example 2

[0047] refer to Figures 4 to 8 The device provided by the utility model comprises a tape forming mechanism 2 and the above-mentioned lithium battery shell gluing mechanism, and the tape forming mechanism 2 is located on the operation path of the gluing mechanism 1. Specifically, the tape forming mechanism 2 comprises a fixed platform 21 and a forming module 22, and the forming module 22 comprises a driving unit 221 and a forming member 222 connected to the driving end of the driving unit 221, and the forming member 222 is located at the periphery of the fixed platform 21, and is used to bend and form at least one side of the tape.

[0048] In some embodiments, the driving unit 221 is a lifting driving cylinder, which drives the forming member 222 to rise to achieve the bending and forming action of the side of the adhesive tape. The specific operation process is that the gluing mechanism 1 adsorbs the adhesive tape to the position of the adhesive tape forming mechanism 2, so that the adhesive tape body is placed on the fixed platform 21, and the driving unit 221 drives the forming member 222 to rise, so that the forming member 222 pushes the side of the adhesive tape to bend upward to form, and the adhesive tape forming operation is completed. By bending and forming the side of the adhesive tape by the adhesive tape forming mechanism 2, the consistency of the bending part of the side of the adhesive tape can be achieved, the matching degree of the size and shape of the adhesive tape with the size and shape of the battery shell can be improved, and the production quality can be improved.

[0049] In some embodiments, there are two adhesive modules 12, and two adhesive tape forming mechanisms 2, and one adhesive tape forming mechanism 2 can be used to bend and form two opposite sides of the adhesive tape, and the other adhesive tape forming mechanism 2 can be used to bend and form three sides of the adhesive tape. In this way, the adhesive tapes of different specifications on the same battery housing can be synchronously bent and formed, which is highly versatile and has high operating efficiency.

[0050] As a further optimization, the contact part between the forming piece 222 and the side of the adhesive tape is provided with a third roller 2221. The side of the adhesive tape is rolled and formed by the third roller 2221, which has a better forming effect and can also reduce the friction between the forming piece 222 and the adhesive tape, preventing the adhesive tape from being scratched or abraded during the forming process, thereby affecting the product quality.

[0051] As a further optimization, the device further includes a tape feeding mechanism 3 and a battery shell conveying mechanism 4 located on the working path of the glue sticking mechanism 1. In some embodiments, the tape feeding mechanism 3 can be a feeder feeder. Specifically, the battery shell conveying mechanism 4 includes a mobile module 41 and a battery shell positioning module 42 connected to the driving end of the mobile module 41.

[0052] As one embodiment, the battery casing positioning module 42 includes a positioning platform and a first positioning unit and a second positioning unit respectively located on adjacent sides of the positioning platform. A first retaining wall is provided on the positioning platform on the side opposite to the position of the first positioning unit, and a second retaining wall is provided on the positioning platform on the side opposite to the position of the second positioning unit. The first positioning unit can push the battery casing against the first retaining wall, and the second positioning unit can push the battery casing against the second retaining wall, thereby realizing the positioning and fixation of the battery casing.

[0053] As a further optimization, the device also includes a shaping mechanism 5, which is located in the conveying direction of the battery shell conveying mechanism 4. When the battery shell is completed with the adhesive tape attached, it will move to the position of the shaping mechanism 5 to perform the shaping operation of the adhesive tape. Specifically, the shaping mechanism 5 includes a second driving module 51 and a shaping module 52 connected to the driving end of the second driving module 51. In some embodiments, the second driving module 51 is an up-and-down moving module that can drive the shaping module 52 to press down the adhesive tape body to achieve the shaping of the adhesive tape.

[0054] In some embodiments, the driving end of the second driving module 51 is connected to the second mounting plate 511, and the shaping module 52 is arranged on the second mounting plate 511. The shaping module 52 includes a fixed block 521 connected to the second mounting plate 511, and a second slide rail 522 is arranged on the second mounting plate 511 in a horizontal direction. The first shaping block 523 and the second shaping block 524 are slidably connected to the second slide rail 522. A second spring 525 is connected between the first shaping block 523 and the second shaping block 524 in a horizontal direction. The first shaping block 523 and the second shaping block 524 are respectively located on opposite sides of the fixed block 521. The shaping module 52 further includes a second transmission block 526 movable in the vertical direction, the second transmission block 526 is located above the first shaping block 523 and the second shaping block 524, a third transmission part 527 and a fourth transmission part 528 are formed at the end of the second transmission block 526, the third transmission part 527 abuts against the first shaping block 523, the fourth transmission part 528 abuts against the second shaping block 524, and the second transmission block 526 is used to drive the first shaping block 523 and the second shaping block 524 to move closer to or away from each other. Since the transmission principle of the second transmission block 526 is the same as that of the transmission block 1226, it will not be described in detail here.

[0055] As one embodiment, when the shaping module 52 moves downward under the drive of the second driving module 51, the fixed block 521 presses against one side area and the corresponding bent side of the adhesive tape body, and the first shaping block 523 and the second shaping block 524 press against the two opposite side areas of the adhesive tape body respectively. When the first shaping block 523 and the second shaping block 524 move away from each other under the transmission of the second transmission block 526, the corresponding bent side of the adhesive tape can be pushed against the inner wall of the battery shell respectively, so as to realize the shaping of the adhesive tape attached to the battery shell. Through the shaping operation of the shaping mechanism 5, the fit between the adhesive tape and the battery shell can be further improved, so that the adhesive tape is attached more tightly, thereby effectively improving the production quality of battery products.

[0056] In some embodiments, rollers are provided at the abutting parts of the third transmission part 527 and the first shaping block 523, and at the abutting parts of the fourth transmission part 528 and the second shaping block 524. The provision of rollers can make the transmission process of the second transmission block 526 smoother, which is conducive to improving the operation production efficiency.

In some embodiments, the first visual inspection mechanism 6, the second visual inspection mechanism 7, and the third visual inspection mechanism 8 are all CCD cameras.

[0059] The first visual inspection mechanism 6 is used to take photos and position the loaded adhesive tape, so as to ensure that the position and size of the adhesive tape taken by the gluing mechanism 1 are consistent with the position and size of the gluing module 12, and indirectly control the shape and size of the subsequent bending and forming of the adhesive tape. The second visual inspection mechanism 7 is used to take photos and position the battery shell, so that the gluing mechanism 1 can lock the position of the battery shell, which is conducive to improving the accuracy of the subsequent gluing operation. The third visual inspection mechanism 8 is used to take photos and position the adhesive tape after bending and forming, so that the gluing mechanism 1 can more accurately align the adhesive tape to the inner wall of the battery shell to ensure the quality of the operation.
