[0092] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention are further described below in conjunction with the accompanying drawings and through specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, not all.

[0093] like Figure 1 As shown, this embodiment provides a glue coating and edge sealing production line for gluing and edge sealing battery cells, wherein the battery cells include a battery cell body and a battery cell skirt. The glue coating and edge sealing production line includes a cutting device for trimming and / or corner trimming the battery cell skirt, a first skirt shaping device 5, a glue coating device 91, a glue coating detection device and a folding shaping device, which are sequentially arranged along a preset conveying direction, a jig reflow device 2 for conveying the battery cells along a preset conveying direction, and a loading device capable of loading at least two battery cells onto the jig reflow device 2.

[0094] like Figure 2 As shown, the fixture reflow device 2 is provided with a plurality of battery fixtures 1 for clamping the battery cells, and each battery fixture 1 can position and clamp N battery cells at the same time, where N is greater than or equal to 2. Specifically, as Figure 2 As shown, the battery fixture 1 includes an upper connecting plate 10, N upper pressing blocks 11, a lower connecting plate 16, N lower pressing blocks 12, a lifting assembly and a fixture bottom plate 15, wherein the N upper pressing blocks 11 are distributed along the extension direction of the battery core skirt, and the lower pressing blocks 12 and the upper pressing blocks 11 are arranged one by one and are located directly below the corresponding upper pressing blocks 11. Among them, the N upper pressing blocks 11 are all connected to the lower surface of the upper connecting plate 10, and the lower pressing blocks 12 are all connected to the lower connecting plate. In this embodiment, N=2 is taken as an example.

[0095] The lifting assembly includes a lifting rod 132, a lifting block 131 and a connecting rod unit. The upper end of the lifting rod 132 is connected to the lifting block 131. The lower end of the lifting rod 132 passes through the upper connecting plate 10 and the lower connecting plate 16 in sequence and is connected to the connecting rod unit. The lifting rod 132 is slidably connected to the lower connecting plate 16. The fixture bottom plate 15 is located below the connecting rod unit and the lower connecting plate 16. One end of the connecting rod unit is rotatably connected to the fixture bottom plate 15, and the other end is rotatably connected to the lower connecting plate 16.

[0096] The battery cell jig 1 further includes an elastic reset member 17, preferably, the elastic reset member 17 is a tension spring or a compression spring. One end of the elastic reset member 17 is connected to the jig bottom plate 15, and the other end is connected to the lower connecting plate 16. When the lifting block 131 pulls the lifting rod 132 upward, the connecting rod unit drives the lower connecting plate 16 to descend, so that the battery cell is clamped between the upper connecting plate 10 and the lower connecting plate 16, and the elastic reset member 17 will be compressed.

[0097] When the upper pressing block 11 and the lower pressing block 12 are needed to clamp the battery cell, the elastic reset member 17 will push the lower connecting plate 16 up, so that the battery cell is clamped between the lower connecting plate 16 and the upper connecting plate 10; at the same time, the lower connecting plate 16 will cause the connecting rod unit to pull the lifting rod 132 down, thereby resetting the lifting assembly.

[0098] By using the battery cell fixture 1 provided in this embodiment, two battery cells can be positioned and clamped at one time, and after being clamped and positioned, only the upper and lower surfaces of the battery cells are in contact with the battery cell fixture 1, and the glue edge sealing is mainly for the battery cell skirt. The use of the above-mentioned battery cell fixture 1 will not affect the glue edge sealing of the battery cell skirt, and the battery cells are positioned and clamped from the upper and lower directions, and the position of the battery cell in the width direction will not change, thereby improving the accuracy of battery cell positioning.

[0099] In this embodiment, the connecting rod unit is a symmetrical structure about the lifting assembly, specifically, the connecting rod unit includes a first connecting rod 141 connected to the lower end of the lifting rod 132, and both ends of the first connecting rod 141 are hinged with a second connecting rod 142, and the end of the second connecting rod 142 away from the first connecting rod 141 is hinged to the third connecting rod 143 and the fourth connecting rod 144 through the same hinge axis. Among them, the third connecting rod 143 is hinged to the fixture bottom plate 15, the fourth connecting rod 144 is hinged to the fifth connecting rod 145, and the fifth connecting rod 145 is connected to the lower connecting plate 16.

[0100] like Figures 3 to 5 As shown, the jig reflow device 2 is used to transport the battery jig 1 loaded with battery cells along a preset conveying direction, and can return the battery jig 1 located at the unloading end of the preset conveying direction to the loading end of the preset conveying direction.

[0101] Specifically, the above-mentioned jig reflow device 2 also includes two reflow lifting components and two horizontal reflow components. The reflow lifting components are respectively a first reflow lifting component and a second reflow lifting component 22. The first reflow lifting component is located at the loading end of the preset conveying direction, and the second reflow lifting component 22 is located at the unloading end of the preset conveying direction; the two horizontal reflow components are respectively a first horizontal reflow component 21 and a second horizontal reflow component 23. The first horizontal reflow component 21, the second reflow lifting component 22, the second horizontal reflow component 23 and the first reflow lifting component form a cycle.

[0102] Among them, the first horizontal reflux component 21 is used to convey the battery cell fixture 1 loaded with battery cells along the preset conveying direction, and the second horizontal reflux component 23 conveys the battery cell fixture 1 without battery cells along the preset reflux direction. The above preset conveying direction and the preset reflux direction are opposite. The second reflux lifting component 22 is used to convey the battery cell fixture 1 at the unloading end of the first horizontal reflux component 21 to the loading end of the second horizontal reflux component 23, and the first reflux lifting component is used to convey the battery cell fixture 1 at the unloading end of the second horizontal reflux component 23 to the loading end of the first horizontal reflux component 21, so as to realize the recycling of the battery cell fixture 1.

[0103] The first horizontal reflux assembly 21 includes a first conveying section and a second conveying section 25 sequentially distributed along a preset conveying direction. Both the first conveying section and the second conveying section 25 can convey the battery cell fixture 1 with battery cells clamped therein along the preset conveying direction.

[0104] Among them, the cutting device, the cutting device, the skirt shaping device, the gluing device 91, and the gluing detection device are all distributed corresponding to the first conveying section, the folding shaping device is arranged corresponding to the second conveying section 25, and the second conveying section 25 is provided with two, and the two second conveying sections 25 are horizontally distributed along the direction perpendicular to the skirt of the hot-pressed battery cell to be rolled, and the two second conveying sections 25 can move horizontally along the direction perpendicular to the skirt of the hot-pressed battery cell to be rolled, so that the two second conveying sections 25 are alternately docked with the first conveying section to receive the battery cell fixture 1 with the battery cell transported by the first conveying section; and the two second conveying sections 25 can also be alternately docked with the second reflow lifting assembly 22 to transport the battery cell fixture 1 on the second conveying section 25 to the second reflow lifting assembly 22.

[0105] It should be noted that when the first conveying section is docked with one of the second conveying sections 25 , the other second conveying section 25 is docked with the second reflux lifting assembly 22 .

[0106] The first conveying section and the second conveying section 25 have the same structure, and only the specific structure of the first conveying section is described below. Figure 3As shown, the first conveying section includes a first reflow slide rail 211 extending along a preset conveying direction, each battery cell fixture 1 also includes a fixture slide 20 arranged under the fixture base plate 15, and multiple fixture slides 20 are slidably arranged on the first reflow slide rail 211 in sequence. The first horizontal reflow assembly 21 also includes a lifting slide 214, a first reflow lifting unit that drives the lifting slide 214 to rise and fall, and a first horizontal reflow unit that drives the first reflow lifting unit to move horizontally.

[0107] Each jig slide 20 is provided with two reflow blocks 20 distributed along the preset conveying direction on both sides of the preset conveying direction, and two first reflow slots are provided on the lifting slide 214. The first reflow lifting unit is lifted and lowered regularly so that the two first reflow slots can be inserted into two adjacent reflow blocks 20 at the same time, so as to realize the vertical connection between the reflow support block 221 and the first reflow slot.

[0108] The first reflux lifting unit is a cylinder, and the first horizontal reflux unit includes a reflux motor 212 and a reflux screw 213. The first reflux lifting unit is connected to the reflux screw 213. The reflux motor 212 drives the reflux screw 213 to rotate, thereby driving the first reflux lifting unit to move horizontally, and realizing the horizontal movement of the battery fixture 1 along the preset conveying direction. In this embodiment, there are multiple first horizontal reflux units, and the lifting slide 214 corresponds to the first horizontal reflux unit one by one. The multiple first horizontal reflux units are distributed along the preset conveying direction to realize the continuous conveying of the battery fixture 1 along the preset conveying direction.

[0109] like Figure 4 As shown, the second horizontal reflux assembly 23 is located directly below the first horizontal reflux assembly 21, and includes a second reflux rail 231 that slides with the battery fixture 1 and extends along a preset reflux direction, a first reflux plug plate 232, a second horizontal reflux unit 233 that drives the first reflux plug plate 232 to move horizontally in a direction perpendicular to the preset conveying direction, and a third horizontal reflux unit 234 that drives the second horizontal reflux unit 233 to move horizontally in the preset conveying direction. Among them, a second reflow slot is provided on the first reflow plug plate 232, and the second horizontal reflow unit 233 drives the first reflow plug plate 232 to move horizontally in a direction perpendicular to the preset conveying direction so that the second reflow slot is plugged into the reflow plug block 20. The second horizontal reflow unit 233 adopts a cylinder, and the third horizontal reflow unit 234 is a motor gear rack structure. The second horizontal reflow unit 233 is driven by the third horizontal reflow unit 234 to move horizontally along the preset reflow direction, so as to drive the battery fixture 1 to move horizontally along the preset reflow direction and send the battery fixture 1 to the first reflow lifting assembly.

[0110] In the present embodiment, a plurality of second horizontal reflux components 23 are provided, and the plurality of second horizontal reflux components 23 are sequentially distributed along a preset reflux direction, so as to realize continuous conveyance of the battery cell fixture 1 along the preset reflux direction.

[0111] In order to ensure the stability of the transportation of the battery fixture 1, the third horizontal reflux component 24 is added in this embodiment, and the second horizontal reflux component 23 and the third horizontal reflux component 24 are arranged on both sides of the preset reflux direction. The third horizontal reflux component 24 includes a reflux manipulator 241 and a reflux cylinder 242. The protruding end of the reflux cylinder 242 is provided with a second reflux plug plate 243, and the second reflux plug plate 243 is provided with a third reflux slot. The reflux cylinder 242 drives the second reflux plug plate 243 to move horizontally in a direction perpendicular to the preset transportation direction, so that the third reflux slot is plugged into the reflux plug block 20. The reflux manipulator 241 is a single-axis manipulator, which is used to drive the reflux cylinder 242 to move horizontally along the preset reflux direction, so as to realize the horizontal movement of the battery fixture 1 along the preset reflux direction.

[0112] The first reflux lifting assembly and the second reflux lifting assembly 22 have the same structure. The following only describes the structure of the second reflux lifting assembly 22. Figure 5 As shown, the second reflux lifting assembly 22 includes a reflux support block 221 and a second reflux lifting unit 222 for driving the reflux support block 221 to lift. The second reflux lifting unit 222 is a lifting structure composed of a motor, a belt and a slide rail. This structure is a prior art and will not be described in detail here.

[0113] The specific process of using the jig reflow device 2 to transport the battery jig 1 is as follows:

[0114] The first reflow lifting unit drives the lifting slide 214 to rise so that the two first reflow slots are simultaneously inserted into the two adjacent reflow plug blocks 20, and the first horizontal reflow unit drives the first reflow lifting unit to move along the preset conveying direction to drive the battery cell fixture 1 to slide horizontally relative to the first reflow slide rail 211 along the preset conveying direction, so that the battery cell fixture 1 gradually approaches the second conveying section 25.

[0115] The two second conveying sections 25 are driven to move horizontally so that the first reflow slide 211 of one of the second conveying sections 25 is docked with the first reflow slide 211 of the first conveying section, and the second conveying section 25 receives the battery cell fixture 1 conveyed by the first conveying section; at the same time, the second reflow lifting unit 222 is used to drive the reflow support block 221 to rise and fall so that the reflow support block 221 is docked with the first reflow slide 211 of the other second conveying section 25, so as to send the battery cell fixture 1 conveyed by the second conveying section 25 to the second horizontal reflow assembly 23 through the second reflow lifting unit 222.

[0116] The reflow support block 221 receives the battery cell fixture 1 conveyed by the second conveying section 25, and then the first reflow lifting unit drives the lifting slide 214 to descend, and the first horizontal reflow unit drives the first reflow lifting unit to drive the lifting slide 214 to move along the preset reflow direction to convey another battery cell fixture 1; at the same time, the second reflow lifting unit 222 drives the reflow support block 221 to descend, and at the same time, the third horizontal reflow unit 234 drives the second horizontal reflow unit 233 to move in the preset conveying direction, and the second horizontal reflow unit 233 is used to drive the first reflow plug 232 to move horizontally in a direction perpendicular to the preset conveying direction, so that when the second reflow lifting unit 222 drives the reflow support block 221 to descend to dock with the second reflow slide rail 231, the reflow plug 20 is just inserted into the second reflow slot, and then the second horizontal reflow unit 233 is driven by the third horizontal reflow unit 234 to move horizontally along the preset reflow direction to realize the horizontal movement of the battery cell fixture 1 along the preset reflow direction.

[0117] When the second horizontal reflux assembly 23 conveys the cell jig 1 to the first lifting reflux assembly, the first lifting reflux assembly drives the cell jig 1 to rise to convey the cell jig 1 to the loading end of the first horizontal reflux assembly 21 , thereby realizing the recycling of the cell jig 1 .

[0118] Please refer again Figure 1 The feeding device includes a feeding assembly 100, a cell flipping assembly 200, a feeding robot 300, a double-station turntable 400 and a handling robot 500 which are sequentially arranged along the cell conveying direction, wherein the feeding assembly 100 is a belt conveying structure, and the cell flipping assembly 200 is used for CCD photographing and detecting the upper and lower surfaces of the cell in the vertical direction. The feeding assembly 100 and the cell flipping assembly 200 are both prior arts and will not be described in detail herein.

[0119] The above-mentioned double-station turntable 400 is provided with four stations, two of which are battery cell placement positions and two are loading positions. The feeding robot 300 is used to transport the battery cells processed by the battery cell flipping assembly 200 to the battery cell placement position, and the double-station turntable 400 is driven by a motor to rotate 180° once to transport the two battery cells placed at the battery cell placement position to the loading position. The above-mentioned transport robot 500 adopts a four-axis robot, which is used to transport the battery cells at the loading position to the battery cell fixture 1 located at the loading end of the first horizontal reflux assembly 21 at one time.

[0120] This embodiment adopts a double-station turntable 400 to transport two battery cells to the loading position at one time, and then uses a handling robot 500 to transport the battery cells at the loading position to the battery cell fixture 1 at the loading end of the first horizontal reflux component 21, which greatly improves the efficiency of gluing and edge sealing of the battery cells.

[0121] like Figure 6As shown, a second skirt shaping device 3 is provided upstream of the cutting device, such as Figure 6 As shown, the second skirt shaping device 3 is provided with a skirt shaping placement position 31 corresponding to the loading position one by one, and the handling robot 500 is used to transport the battery cells at the loading position to the skirt shaping placement position 31 at one time to perform skirt shaping on the battery cells; the handling robot 500 is also used to transport the battery cells that have undergone skirt shaping by the second skirt shaping device 3 to the battery cell jig 1 located at the loading end of the jig reflux device 2, and the cutting device is located at the loading end of the jig reflux device 2, and is used to perform skirt cutting and corner cutting on two battery cells in turn at the same time.

[0122] The above-mentioned second skirt shaping device 3 includes two shaping cell positioning components, two first upper shaping hot pressing blocks 32, and two first lower shaping hot pressing blocks 33, wherein the shaping cell positioning component is used to support the battery cell and position the battery cell, and two skirt shaping placement positions 31 are arranged thereon. A handling robot 500 is used to transport the two battery cells at the loading position to the corresponding skirt shaping placement positions 31. The shaping cell positioning component uses negative pressure adsorption to position the battery cell, and its specific structure is not repeated here.

[0123] The two first upper shaping hot pressing blocks 32 are arranged on both sides of the extension direction of the battery cell skirt, and can be moved closer or farther away from each other to clamp the battery cell skirt and perform hot pressing shaping on the battery cell skirt. The distance between the two first upper shaping hot pressing blocks 32 can be adjusted according to the battery cells of different sizes. In this embodiment, a horizontal shaping drive 35 composed of a gear rack structure driven by a motor is used to adjust the distance between the two first upper shaping hot pressing blocks 32. The two first lower shaping hot pressing blocks 33 are located below the corresponding first upper shaping hot pressing blocks 32, and a vertical shaping cylinder 34 is used to drive the two first lower shaping hot pressing blocks 33 to rise and fall synchronously, so as to perform hot pressing shaping on the lower surface of the battery cell skirt.

[0124] The cell skirt is clamped by two first upper shaping hot pressing blocks 32 and two first lower shaping hot pressing blocks 33, and then the two first upper shaping hot pressing blocks 32 and two first lower shaping hot pressing blocks 33 work to generate heat so as to perform hot pressing and shaping on the cell skirt; the cell after hot pressing treatment by the first skirt shaping device 5 is transported by the handling robot 500 to the cell fixture 1 at the feeding end of the fixture reflow device 2, and the cell is clamped by the cell fixture 1.

[0125] The above-mentioned first skirt shaping device 5 performs hot pressing shaping after the cutting device cuts the battery cell skirt. The first skirt shaping device 5 includes a second upper shaping hot pressing block and a second lower shaping hot pressing block arranged on both sides of the preset conveying direction. The battery cell is conveyed between the two upper shaping hot pressing blocks by the jig reflux device 2, and the battery cell jig 1 is used to clamp the battery cell. The two first cylinders work synchronously to drive the two second upper shaping hot pressing blocks to approach or move away from each other, so as to adjust the distance between the two second upper shaping hot pressing blocks, and the upper surface of the battery cell skirt is shaped. The two second cylinders work synchronously to drive the two second lower shaping hot pressing blocks to rise and fall, so as to perform hot pressing shaping on the lower surface of the battery cell skirt.

[0126] like Figure 1 As shown, the cutting device includes a first skirt cutting component 41, a second skirt cutting component 42 and a corner cutting component 43 which are sequentially arranged along the battery cell conveying direction, and the jig reflow device 2 sequentially conveys the battery cell fixture loaded with the battery cells to the first skirt cutting component 41, the second skirt cutting component 42 and the corner cutting component 43, wherein the first skirt cutting component 41 and the second skirt cutting component 42 respectively cut the two battery cell skirts of the battery cells, and the structures of the first skirt cutting component 41 and the second skirt cutting component 42 are both prior arts and will not be repeated herein.

[0127] like Figures 7 to 10 As shown, the above-mentioned corner cutting component 43 is used to cut multiple corners of the battery cell. The above-mentioned corner cutting component 43 is set in two, and the two corner cutting components 43 are arranged on both sides of the preset conveying direction and are both arranged on the corner cutting frame 431, which can simultaneously cut the four corners of the battery cell skirt.

[0128] In this embodiment, each corner cutting component 43 includes a corner cutting unit 432, and a corner cutting manipulator 433 for driving the corner cutting unit 432 to move in multiple axes, wherein the corner cutting unit 432 includes a first corner cutting portion 4321 and a second corner cutting portion 4322 which are adjacently arranged and have adjustable spacing, so that each corner cutting unit 432 can cut two corners of a cell skirt, and at the same time meet the cutting of cell skirts of various sizes. In addition, in order to prevent the cell from being contaminated when the cell skirt is cut, this embodiment further provides a dust removal portion 4323 between the first corner cutting portion 4321 and the second corner cutting portion 4322, which can use an air pipe with air holes on the outer peripheral surface to blow and remove dust from the cell. The specific structural design of this part is more commonly used in the prior art, and will not be described in detail here.

[0129] In this embodiment, the first corner cutting part 4321 and the second corner cutting part 4322 have the same structure, both of which include a vertically arranged corner cutting guide block 4324, an upper cutter 4325 and a lower cutter 4326 arranged along the length direction of the corner cutting guide block 4324, and a first corner cutting cylinder 4327 for driving the upper cutter 4325 and the lower cutter 4326 to close and cut the corners of the corresponding cell skirt. The first corner cutting cylinder 4327 in this embodiment is connected to the upper cutter 4325 slidably arranged on the corner cutting guide block 4324. With this structural design, the two corners of a cell skirt are synchronously cut by the first corner cutting part 4321 and the second corner cutting part 4322, and the two corner cutting components 43 can correspondingly synchronously cut the four corners of the cell skirt, which effectively improves the cutting efficiency of cutting the corners of the cell skirt.

[0130] In this embodiment, the first corner cutting part 4321 and the second corner cutting part 4322 of the same corner cutting component 43 are both arranged on the corner cutting support plate 434, and the corner cutting manipulator 433 drives the corner cutting support plate 434 to rise and fall in the vertical direction, move horizontally in the extension direction of the cell skirt, and move horizontally in the direction perpendicular to the cell skirt. As for the structure of the corner cutting manipulator 433, it is prior art and will not be described in detail here.

[0131] In order to facilitate the adjustment of the spacing between the first corner cutting portion 4321 and the second corner cutting portion 4322 so as to meet the cutting requirements of the corners of the cell skirt of different specifications, one of the first corner cutting portion 4321 and the second corner cutting portion 4322 can move horizontally along the extension direction of the cell skirt. In this embodiment, the second corner cutting portion 4322 can move horizontally along the extension direction of the cell skirt as an example. Specifically, the second corner cutting portion 4322 is slidably arranged on the corner cutting support plate 434, and the corner cutting support plate 434 is provided with a corner cutting adjustment screw 435, which drives the second corner cutting portion 4322 to move horizontally along the extension direction of the cell skirt to be cut. A dividing head is provided at one end of the corner cutting adjustment screw 435, so as to accurately adjust the gap between the first corner cutting portion 4321 and the second corner cutting portion 4322.

[0132] In this embodiment, the end of the cutting angle support plate 434 away from the first cutting angle portion 4321 is pivotally connected to a cutting angle support seat 436 for mounting the second cutting angle portion 4322, and the cutting angle support seat 436 is provided with an arc-shaped slide groove 4361 for adjusting the cutting angle of the second cutting angle portion 4322, and the cutting angle support seat 436 is connected to an external driving mechanism. In this way, the cutting angle support seat 436 is driven to rotate around the arc-shaped slide groove 4361, and then the cutting angle of the second cutting angle portion 4322 is adjusted, so as to meet the cutting of the edges and corners of the battery core at different angles. According to design requirements, the first cutting angle portion 4321 can also be made adjustable in a similar manner to the second cutting angle portion 4322, which will not be described in detail here.

[0133] Furthermore, a slide groove 4363 for pivotally connecting to the second corner cutting portion 4322 is also provided at a position of the corner cutting support seat 436 close to the arc-shaped slide groove 4361. The slide groove 4363 is also arranged in an arc shape. In order to facilitate the rotation of the second corner cutting portion 4322, bearings pivotally connected to the corner cutting support plate 434 can be respectively arranged in the arc-shaped slide groove 4361 and the slide groove 4363, so that the second corner cutting portion 4322 can rotate smoothly when the angle is adjusted under the action of external force.

[0134] Furthermore, in order to facilitate the timely discharge of the scraps after cutting, the present embodiment is provided with waste guide grooves on the first corner cutting portion 4321 and the second corner cutting portion 4322. The waste guide grooves are located below the lower cutting knife 4326. The waste guide grooves are connected with the through holes 4362 on the corner cutting support seat 436, so that the through holes 4362 are connected with the openings on the corner cutting support plate 434, thereby allowing the waste of the second corner cutting portion 4322 to be discharged. The waste discharge structure of the first corner cutting portion 4321 can be designed with reference to the first corner cutting portion 4321, and no detailed description is given here.

[0135] The above-mentioned corner cutting unit 432 also includes a cell pressing mechanism 437 mounted above the corner cutting frame 431, and a corner cutting shooting structure 438 mounted above the cell pressing mechanism 437 and used for capturing images of the cell before corner cutting. The above-mentioned cell pressing mechanism 437 includes a corner cutting fixing plate 4371 disposed above the cell to be corner cut, a second corner cutting cylinder 4373 that drives the corner cutting fixing plate 4371 to move in a vertical direction and is connected to the corner cutting frame 431, and a corner cutting positioning group 4372 that can move horizontally in a direction perpendicular to the skirt of the cell to be corner cut, and the corner cutting positioning group 4372 is used to position the cell along the extension direction of the skirt of the cell to be corner cut.

[0136] When the battery cell moves to the corner cutting component 43, the corner cutting shooting structure 438 takes a picture of the battery cell before corner cutting to determine the position of the battery cell skirt, and then the battery cell is positioned by the corner cutting positioning group 4372; thereafter, the second corner cutting cylinder 4373 drives the corner cutting fixing plate 4371 to move toward the battery cell side to flatten the battery cell; and then the corner cutting component 43 is used to cut the edges of the battery cell skirt.

[0137] like Figures 11 to 20As shown, the glue coating device 91 is used to coat UV glue on the upper surface and the lower surface of the cell skirt to connect the outer wall of the upper surface and the lower surface. The glue coating device 91 includes a glue coating module 911 and a camera positioning module. There are two glue coating modules 911. The two glue coating modules 911 are located on both sides of the preset conveying direction. Each glue coating module 911 includes two glue coating components 912 arranged vertically opposite to each other. The two glue coating components 912 are used to coat the upper surface and the lower surface of the cell skirt respectively, and use the glue sprayed from the upper surface and / or the lower surface to cover the outer wall of the cell skirt.

[0138] The two glue coating modules correspond to the four glue coating components, which can simultaneously coat the upper and lower surfaces of the two battery cell skirts and the outer walls of the battery cell skirts, greatly improving the glue coating efficiency and thus improving the production efficiency of the battery cells.

[0139] The camera positioning module is used to photograph the battery cell to determine the position of the battery cell. In the actual working process, after the jig reflow device transports the battery cell to the glue coating device 91, the camera positioning module can photograph the position of the battery cell. The glue coating module 911 can accurately apply glue according to the position of the battery cell photographed by the camera positioning module during the actual glue coating process, thereby improving the glue coating accuracy of the glue coating device 91 and reducing the scrap rate in the battery cell production process. It should be supplemented here that the battery cell glue coating module 911 of this embodiment should also include a control system, and the control system can receive the image information photographed by the camera positioning system, and send a control signal to the glue coating module 911 according to the image information to make it move to a more accurate glue coating position. In this embodiment, the type of control system, the image processing process, and the control logic between the control system and the camera positioning module and the glue coating module 911 can all be selected according to the existing image processing positioning software and the automatic control system. In other words, the camera positioning module and the control system can select existing products according to actual needs.

[0140] Each glue coating component 912 includes a glue coating support seat 9121, a glue coating slide 9122, a first glue coating drive unit 9123, a glue coating slide 9122, a glue dispensing machine 9124, a second glue coating drive unit 9125 and a third glue coating drive unit 9127. The glue coating slide 9122 is slidably disposed on the glue coating support seat 9121 along a preset conveying direction. The first glue coating drive unit 9123 cooperates with the glue coating slide 9122 to drive the glue coating slide 9122 to move along the preset conveying direction. The glue dispensing machine 9124 is slidably disposed on the glue coating slide 9122 along the vertical direction. The second glue coating drive unit 9125 cooperates with the glue dispensing machine 9124 to drive the glue dispensing machine 9124 to slide vertically.

[0141] It is understandable that in the actual process of gluing, after the battery cell is positioned, the second gluing drive unit 9125 and the third gluing drive unit 9127 drive the glue dispenser 9124 to move horizontally in the vertical direction and in the direction perpendicular to the skirt of the battery cell to be glued, and move it to the specified position. The distance between the glue dispenser 9124 and the skirt of the battery cell can be selected according to actual needs and is not limited here. When the glue dispenser 9124 moves to a suitable position, the first glue drive unit 9123 drives the glue slide 9122 to move horizontally in the direction perpendicular to the skirt of the battery cell to be glued to achieve glue coating, thereby realizing automatic glue dripping of the glue dispenser 9124.

[0142] It should be noted that the first gluing drive unit 9123, the second gluing drive unit 9125 and the third gluing drive unit 9127 in this embodiment can be linear drive structures such as linear motors, electric push rods, and cylinders. The specific types of the first gluing drive unit 9123, the second gluing drive unit 9125 and the third gluing drive unit 9127 are not limited here, and the types of the first gluing drive unit 9123, the second gluing drive unit 9125 and the third gluing drive unit 9127 can be comprehensively selected according to actual driving needs and purchase costs.

[0143] The glue dispensing machines 9124 of the two glue coating components 912 are staggered in a direction perpendicular to the skirt of the battery cell to be glued. Each glue coating component 912 also includes a glue receiving unit 9126, which is used to receive glue drops leaking from the skirt of the battery cell. In the gluing direction of the glue coating component 912, the glue receiving unit 9126 is located upstream of the glue dispensing machine 9124. Each glue receiving unit 9126 includes two glue coating pulleys 91261 and a glue coating conveyor belt 91262 extending along the gluing direction and cooperating with the two glue coating pulleys 91261.

[0144] During the glue dripping process, glue may drip to places other than the cell skirt, and glue dripping to other places may increase the risk of failure of the entire glue coating device 91. In this embodiment, the glue connection unit 9126 is arranged upstream of the glue dispenser 9124. In the actual glue coating process, the glue connection unit 9126 of one glue coating component 912 is located below the glue dispenser 9124 of another glue coating component 912. In this way, the glue dripping outside the cell skirt can be received by the glue coating conveyor belt 91262 of the glue connection unit 9126 and transported to the waste glue collection device. In this way, the phenomenon of glue contaminating the workshop or affecting the glue coating device 91 is better avoided.

[0145] Of course, it should be additionally explained here that the driving device for the glue coating pulley 91261 to rotate may be a motor or a rotary cylinder, and the specific selection may be made according to actual needs. In addition, in other embodiments of the present invention, the glue connection unit 9126 may also be formed as a glue connection container such as a glue connection tank located upstream of the glue dispensing machine 9124, and is not limited to the structure of the glue coating pulley 91261 in this embodiment in conjunction with the glue coating conveyor belt 91262.

[0146] It should be noted that, in other embodiments of the present invention, each glue dripping assembly may only include a glue dispenser 9124 and a robotic arm capable of driving the glue dispenser 9124 to move in a vertical direction, a direction perpendicular to the skirt of the battery cell to be glued, and a preset conveying direction. The early adjustment of the glue dispenser 9124 and the later glue dripping can also be achieved under the driving action of the robotic arm. In other words, in other embodiments of the present invention, the structure of the glue dripping assembly is not limited to the above description, and can be selected according to actual needs.

[0147] In some more specific embodiments, each glue coating module 911 also includes a first glue coating light source 912, which is slidably connected to the glue coating component 912 located above, and the first glue coating light source 912 has an extended position and a retracted position. Before the glue coating starts, the first glue coating light source 912 is located in the extended position and can illuminate the battery cell. During the glue coating process, the first glue coating light source 912 is located in the retracted position.

[0148] It is understandable that, since the glue coating device 91 of this embodiment includes a camera positioning module, the first glue coating light source 912 capable of illuminating the battery cell can improve the camera clarity of the camera positioning module, improve the positioning accuracy of the battery cell, and thus improve the glue coating accuracy. In addition, the first glue coating light source 912 has an extended position and a retracted position to prevent glue from falling onto the first glue coating light source 912 and contaminating the light source during the glue dripping process.

[0149] The first glue-coated light source 912 includes a first glue-coated light source glue-coated bracket 91419121, a first glue-coated light-emitting component 9122, and a light-emitting driver 9123. The light-emitting driver 9123 can drive the first glue-coated light-emitting component 9122 to move relative to the first light tube glue-coated bracket 9141, thereby realizing the reciprocating motion of the first glue-coated light-emitting component 9122 between the retracted position and the extended position. It should be noted that the light-emitting driver 9123 can be any one of an electric push rod, a cylinder, or a motor-driven ball screw, and the specific type of the light-emitting driver 9123 is not limited here.

[0150] The camera positioning module includes a first glue-coating camera component 913, and there are two first glue-coating camera components 913. The two first glue-coating camera components 913 are spaced apart in a direction perpendicular to the skirt of the battery cell to be glued, and the two first glue-coating camera components 913 are respectively used to photograph the lower surface of the skirt of the battery cell, and the first glue-coating camera component 913 is adjustable along the preset conveying direction. It can be understood that the two first glue-coating camera components 913 can respectively photograph the lower surface of the left skirt and the right skirt. Therefore, in the actual gluing process, the position of the glue-coating components 912 located on the lower side of the two glue-coating modules 911 can be adjusted according to the shooting results, thereby improving the positioning accuracy of the battery cell and improving the gluing accuracy.

[0151] Each first gluing photographing component 913 includes a first gluing rail 9131, a first gluing slider 9132, a first gluing camera 9133, a first gluing knob 9134 and a gluing photographing light source 9135. The first gluing rail 9131 is extended along a preset conveying direction. The first gluing slider 9132 is slidably disposed on the first gluing rail 9131. The gluing photographing light source 9135 is connected above the first gluing camera 9133. The first gluing camera 9133 is connected to the first gluing slider 9132. The first gluing knob 9134 is connected to the first gluing slider 9132. The first gluing knob 9134 is used to lock the first gluing slider 9132 on the first gluing rail 9131.

[0152] In the actual production process, when the model of the battery cell is changed, the position of the first glue-coated camera assembly 913 also needs to change relatively. In this embodiment, the position of the first glue-coated camera 9133 can be adjusted by manually pushing the first glue-coated slider 9132 to make it suitable for different models of batteries. In addition, since the first glue-coated camera assembly 913 of this embodiment includes a first glue-coated knob 9134 for locking the first glue-coated slider 9132, when the position of the first glue-coated camera 9133 is adjusted, the first glue-coated slider 9132 can be locked by the first glue-coated knob 9134, so that the first glue-coated camera 9133 is fixed relative to the first glue-coated slide rail 9131, thereby avoiding the positioning deviation caused by the shaking of the first glue-coated camera 9133 during the photo positioning process.

[0153] Of course, in other embodiments of the present invention, the movement of the first glue-coating camera 9133 can also be adjusted by a driving member such as a motor or a cylinder, and is not limited to the technical solution of manual adjustment in this embodiment. In addition, the first glue-coating camera component 913 can be one, and this first glue-coating camera component 913 can simultaneously capture the lower surface of the left skirt edge and the right skirt edge.

[0154] The camera positioning module also includes a second glue-coating camera component 914, which is located above the battery cell. The second glue-coating camera component 914 is used to photograph the upper surface of the battery cell skirt, and the second glue-coating camera component 914 is adjustable in a direction perpendicular to the battery cell skirt to be glued and in a vertical direction. It can be understood that the second glue-coating camera component 914 can photograph the upper surface of the battery cell skirt, so that in the actual positioning process, the first glue-coating camera component 913 and the second glue-coating camera component 914 can be used in conjunction to achieve accurate positioning of the battery cell, thereby ensuring the glue coating accuracy.

[0155] The second glue coating camera assembly 914 includes a glue coating bracket 9141, a second glue coating slide rail 9142, a glue coating sliding frame 9143, a second camera and a second glue coating slider 9146. The second glue coating slide rail 9142 is connected to the glue coating bracket 9141 and extends in a direction perpendicular to the skirt of the battery cell to be glued. The glue coating sliding frame 9143 is slidably disposed on the second glue coating slide rail 9142. There are two second glue coating camera groups 9145, each of which includes a plurality of second cameras arranged in sequence along a preset conveying direction. The two second glue coating camera groups 9145 are spaced apart in a direction perpendicular to the skirt of the battery cell to be glued. There are a plurality of second glue coating sliders 9146, each of which is slidably disposed on the glue coating sliding frame 9143 in a vertical direction. The plurality of second glue coating sliders 9146 are arranged in a one-to-one correspondence with the plurality of second cameras.

[0156] It is understandable that before the start of gluing, the positions of the multiple second cameras can be adjusted by adjusting the position of the gluing slide 9143 relative to the second gluing slide rail 9142 and the position of the second gluing slider 9146 relative to the gluing slide 9143. In this way, the camera positioning accuracy of the battery cell is better guaranteed, thereby improving the gluing accuracy of the battery cell. It should be additionally explained that in other embodiments of the present invention, there may be only two second cameras, and each second camera can move horizontally along a preset conveying direction relative to a second gluing slider 9146. Of course, the number and movement form of the second camera can be selected according to actual needs. In addition, the movement of the second camera can also be adjusted by a driving member such as a motor or a cylinder, and is not limited to the technical solution of manual adjustment of this embodiment.

[0157] The second gluing knob 9144 is connected to the gluing slide frame 9143, and the second gluing knob 9144 is used to lock the gluing slide frame 9143 on the second gluing slide rail 9142. Therefore, after the position of the gluing slide frame 9143 is adjusted, the second gluing knob 9144 can be used to lock the gluing slide frame 9143 on the second gluing slide rail 9142, thereby better avoiding positioning deviation caused by the shaking of the gluing slide frame 9143 during the camera positioning process.

[0158] The glue coating adjustment bolt 9147 is arranged on the second glue coating slider 9146, and the glue coating adjustment bolt 9147 is used to lock the second glue coating slider 9146 on the glue coating slide frame 9143. Therefore, after the second camera is positioned, the glue coating adjustment bolt 9147 can be used to lock the second glue coating slider 9146 on the glue coating slide frame 9143, thereby better avoiding the positioning deviation caused by the shaking of the second glue coating slider 9146 during the camera positioning process.

[0159] The second glue-coating camera assembly 914 also includes a second glue-coating light source 9148, which is disposed below the second glue-coating camera group 9145. The second glue-coating light source 9148 can move in a direction perpendicular to the edge of the battery cell to be glued. Thus, the second glue-coating light source 9148 can further illuminate the battery cell, so that the second glue-coating camera assembly 914 can more clearly photograph the battery cell, thereby improving the accuracy of the camera positioning.

[0160] The second glue-coated light source 9148 includes a second glue-coated light-emitting component 91481, a second glue-coated light-emitting component glue-coated bracket 91482, a glue-coated light-emitting component slide rail 91483, a glue-coated light-emitting component slide plate 91484, and a glue-coated light-emitting component knob 91485. Therefore, in actual use, the position of the second glue-coated light source 9148 can be adjusted by adjusting the position of the glue-coated light-emitting component slide plate 91484 relative to the glue-coated light-emitting component slide rail 91483, so that the position of the second glue-coated light source 9148 better meets actual needs. At the same time, when the second glue-coated light source 9148 is adjusted into place, the glue-coated light-emitting component slide plate 91484 can be locked on the glue-coated light-emitting component slide rail 91483 by the glue-coated light-emitting component knob 91485, thereby avoiding the phenomenon of unclear photography caused by the shaking of the second glue-coated light-emitting component 91481 during photography.

[0161] The camera positioning module also includes a third glue-coating camera component 915, which is located downstream of the battery cell. The third glue-coating camera component 915 is adjustable in the vertical direction. In the actual production process, the thickness of different types of battery cells is different. The third glue-coating camera component 915 can take pictures of the front side of the battery cell skirt, so that the thickness of the battery cell skirt can be determined according to the shooting results of the third glue-coating camera component 915, so that the height of the glue-coating component 912 can be adjusted according to the shooting results of the third glue-coating camera component 915, thereby improving the accuracy of glue coating.

[0162] The third glue-coating camera assembly 915 includes a glue-coating fixed frame 9151, a third glue-coating slide rail 9152, a third glue-coating slider 9153, a third glue-coating camera 9154, and a glue-coating rotary plunger 9155. The third glue-coating slide rail 9152 is arranged on the glue-coating fixed frame 9151 and extends in the vertical direction, the third glue-coating slider 9153 is slidably arranged on the third glue-coating slide rail 9152, the third glue-coating camera 9154 is connected to the third glue-coating slider 9153, and the glue-coating rotary plunger 9155 is arranged on the third glue-coating slider 9153, and the glue-coating rotary plunger 9155 is used to lock the third glue-coating slider 9153 on the third glue-coating slide rail 9152. Therefore, the third glue coating camera component 915 is located upstream of the battery cell, and the third glue coating camera 9154 can photograph the thickness of the battery cell, thereby providing a reference for adjusting the height position of the glue dispenser 9124 to avoid the height of the glue dispenser 9124 being too high or too low during the glue coating process.

[0163] In addition, it should be noted that in the actual production process, the thickness of different types of battery cells is different, and the shooting range of the third glue-coated camera 9154 will be different. In this embodiment, the third glue-coated camera 9154 can be adjusted in the vertical direction by adjusting the position of the third glue-coated slider 9153 on the third glue-coated slide rail 9152, thereby adjusting the shooting range of the third glue-coated camera 9154. In addition, after the position of the third glue-coated slider 9153 is adjusted, the third glue-coated slider 9153 can be locked on the third glue-coated slide rail 9152 by using a glue-coated rotary plunger 9155, thereby avoiding the third glue-coated camera 9154 shaking during the photo positioning and causing positioning deviation. Of course, in other embodiments of the present invention, the adjustment of the third motor can be achieved by an automatic adjustment mechanism such as an electric push rod and a cylinder push rod.

[0164] The glue coating device 91 also includes a glue wiping module 916, which is arranged on one side of the preset conveying direction. The glue wiping module 916 includes a finger cylinder and a glue wiping drive. The piston rod of the finger cylinder is provided with a glue wiping drive. There are two finger cylinders, and the two finger cylinders are used to clamp the two battery core skirts respectively. The glue wiping drive is connected to the finger cylinder and drives the finger cylinder to move horizontally along the extension direction of the battery core skirt. Therefore, after the glue dispenser 9124 has finished dripping glue, the finger cylinder of the glue wiping module 916 can clamp the two battery core skirts of the battery core, and then move along the extension direction of the battery core skirt under the drive of the glue wiping drive so that the glue dripped on the battery core skirt is evenly distributed on the battery core skirt, thereby better realizing the subsequent battery core packaging process. It should be noted here that the glue wiping drive can be two or one respectively connected to the two finger cylinders, and the glue wiping drive can be a motor or a cylinder or other drive, which can be selected according to actual needs.

[0165] like Figure 1As shown, the above-mentioned glue edge banding production line is provided with a curing device between the glue coating device 91 and the glue coating detection device 8, and two curing devices 7 are provided, and the two curing devices 7 are distributed along the preset conveying direction. Fig.21 As shown, each curing device 7 includes two curing components, which are arranged on both sides of a preset conveying direction, and are used to cure the battery cells placed between the two curing components. Each curing component includes a UV light bracket 71, a UV light base plate 72 and a UV light unit. The UV light bracket 71 can move horizontally relative to the UV light base plate 72 in a direction perpendicular to the skirt of the battery cell to be cured so as to approach or move away from the battery cell. A first horizontal curing drive unit 75 such as a motor screw structure, a cylinder, etc. is used to realize the horizontal movement of the UV light bracket 71 relative to the UV light base plate 72 in a direction perpendicular to the skirt of the battery cell to be cured.

[0166] The UV irradiation unit is arranged on the UV irradiation support 71 and can move horizontally and vertically relative to the UV irradiation bottom plate 72 in a direction perpendicular to the skirt of the battery cell to be cured. The second horizontal curing drive unit 76 such as a motor screw structure, a cylinder, etc. is used to realize the horizontal movement of the UV irradiation unit relative to the UV irradiation support 71 in a direction perpendicular to the skirt of the battery cell to be cured. In this embodiment, the UV irradiation unit includes an upper UV irradiation 73 and a lower UV irradiation 74. The first vertical curing drive unit 77 such as a motor screw structure, a cylinder, etc. is used to realize the lifting and lowering of the upper UV irradiation 73 in the vertical direction, and the second vertical curing drive unit 78 such as a motor screw structure, a cylinder, etc. is used to realize the lifting and lowering of the lower UV irradiation 74 in the vertical direction. Among them, the horizontal distance between the UV irradiation units of the two curing components and the lifting and lowering distance of the upper UV irradiation 73 and the lower UV irradiation 74 of each curing component depend on the size of the battery cell to meet the curing requirements of battery cells of different sizes.

[0167] The first vertical curing drive unit 77, the second vertical curing drive unit 78, the first horizontal curing drive unit 75, and the second horizontal curing drive unit 76 are used to adjust the positions of the upper UV light 73 and the lower UV light 74, so that one of the battery cell skirts is located between the upper UV light 73 and the lower UV light 74 on the same side, and the other battery cell skirt is located between the upper UV light 73 and the lower UV light 74 on the same side, and the UV light unit works to cure the UV glue coated on the upper surface, lower surface and outer wall of the battery cell skirt.

[0168] In this embodiment, the glue detection device 8 is used to detect the UV glue coated on the UV-cured battery cell skirt. When the jig reflux device 2 transports the battery cell jig 1 carrying the battery cell to the glue detection device 8, and when the transport robot 500 transports the battery cell to the battery cell jig 1 located at the loading end of the first conveying section for cutting by the cutting device, the battery cell jig 1 needs to be unclamped first. For this purpose, this embodiment provides an unclamping device 80, and the glue detection device 8 and the cutting device are each equipped with an unclamping device 80. The structure of the unclamping device 80 is introduced below by taking the unclamping device 80 corresponding to the glue detection device 8 as an example.

[0169] like Fig. 22 As shown, the clamping device 80 includes a horizontal clamping cylinder 801 and a vertical clamping cylinder 802, wherein the movable end of the horizontal clamping cylinder 801 is connected with a plug-in block, which is used to drive the plug-in block to be plugged into the lower surface of the lifting block 131 to support the lifting block 131 or to separate the plug-in block from the lifting block 131. The movable end of the vertical clamping cylinder 802 is connected to the fixed end of the horizontal clamping cylinder, which can drive the horizontal clamping cylinder 801 to rise so that the horizontal clamping cylinder 801 drives the lifting assembly to rise, and can also drive the horizontal clamping cylinder 801 to fall.

[0170] In order to prevent the elastic reset member 17 from being realized and causing the battery fixture 1 to be unable to clamp the battery cell, a vertical clamping cylinder is added in this embodiment. The vertical clamping cylinder 803 is used to press down the lifting block 131 to lower the lifting rod 132. In order to prevent the vertical clamping cylinder from interfering with the lifting and lowering of the horizontal clamping cylinder, the vertical clamping cylinder 802 is arranged above the horizontal clamping cylinder, and the movable end of the vertical clamping cylinder 802 is connected to the fixed end of the vertical clamping cylinder 803, and the vertical clamping cylinder 802 synchronously drives the vertical clamping cylinder 803 and the horizontal clamping cylinder to lift and lower.

[0171] In this embodiment, the upper connecting plate 10 and the lifting rod 132 are fixed relative to the lifting rod 132. In the process of lifting the lifting rod 132, the upper connecting plate 10 and the upper pressing block 11 are lifted and lowered synchronously with the lifting rod 132. The above-mentioned clamping device 80 also includes a lifting buffer driving part and a lifting buffer part 804. The lifting buffer driving part is driven to lift and lower by the vertical clamping cylinder 802. One battery cell is equipped with two lifting buffer driving parts. Since in this embodiment, one battery cell fixture 1 conveys two battery cells, four lifting buffer parts 804 are correspondingly provided. The two lifting buffer parts 804 corresponding to one battery cell are arranged on both sides of the preset conveying direction. The lifting buffer part 804 is driven by the lifting buffer driving part to move horizontally in a direction perpendicular to the battery cell skirt, so that the two lifting buffer parts 804 arranged opposite to each other clamp the corresponding upper connecting plate 10 or the corresponding upper pressing block 11, and the upper connecting plate 10 or the upper pressing block 11 is clamped and lifted in the process of the clamping device 80 controlling the battery cell fixture 1 to release the battery cell. During the process of the opening and clamping device 80 controlling the battery cell fixture 1 to clamp the battery cell, after the lower connecting plate 16 is reset, the vertical opening and clamping cylinder 802 drives the lifting buffer part 804 to descend to avoid the battery cell between the lower pressing block 12 and the upper pressing block 11 being damaged due to the rapid reset of the lower connecting plate 16 when the lower connecting plate 16 is reset.

[0172] The process of using the above-mentioned clamping device 80 to control the battery fixture 1 loaded with battery cells to release the battery cells clamped therein is as follows:

[0173] The horizontal clamping cylinder 801 drives the plug-in block to be placed on the lower surface of the lifting block 131, and the vertical clamping cylinder 802 drives the horizontal clamping cylinder 801 to rise, so as to drive the lifting block 131 to rise through the plug-in block, thereby raising the lifting rod 132, and the connecting rod unit will move under the action of the lifting rod 132 to pull the lower pressure plate down, thereby separating the upper pressure plate and the lower pressure plate, and the battery cell fixture 1 releases the battery cell; at the same time, the elastic reset member 17 is compressed.

[0174] The process of using the above-mentioned clamping device 80 to control the battery fixture 1 to clamp the battery cell is as follows: the battery cell is placed on the upper surface of the lower pressure block 12, the horizontal clamping cylinder 801 drives the plug-in block to move so that the plug-in block is separated from the lifting block 131, and the lower connecting plate 16 moves upward under the action of the elastic reset member 17, and the vertical clamping cylinder 802 pushes the horizontal clamping cylinder 801 to descend, and simultaneously drives the lifting buffer part 804 to descend. When it descends to the corresponding designated position, the upper connecting plate 10 or the upper pressure block 11 is released, and then the two lifting buffer parts 804 can move in the direction away from the battery cell, that is, the battery cell is clamped between the upper pressure block 11 and the corresponding lower pressure block 12.

[0175] like Fig. 22 and Fig.23As shown, the above-mentioned glue coating detection device 8 includes a battery cell glue coating conveying component and two glue coating detection components, the two glue coating detection components are sequentially distributed along the preset conveying direction of the battery cell conveying component, and the two battery cell skirts of each battery cell are photographed to determine whether the glue coated on the battery cell skirt is qualified.

The third transfer single-axis manipulator 825 can transport the second transfer lifting cylinder 824 to the top of the second tray 827, and place the battery cells adsorbed by the second transfer adsorption unit 823 in the second tray 827 through the second transfer lifting cylinder 824.

[0180] The third transfer assembly includes a third transfer adsorption unit 831, a third transfer lifting cylinder 832 for driving the third transfer adsorption unit 831 to rise and fall, and a fifth transfer single-axis manipulator 833 for driving the third transfer lifting cylinder 832 to move horizontally in a direction perpendicular to a preset conveying direction.

[0181] The specific process of the above-mentioned glue coating detection device 8 is as follows: the clamping device 80 controls the battery cell fixture 1 transported to the glue coating detection device 8 to release the battery cell; the first transfer single-axis manipulator 813 drives the first transfer lifting cylinder 812 to move to the top of the battery cell released by the battery cell fixture 1, and the first transfer lifting cylinder 812 drives the first transfer adsorption unit 811 to rise and fall, so that the first transfer adsorption unit 811 can adsorb the battery cell; then the first transfer single-axis manipulator 813 cooperates with the first transfer lifting cylinder 812 to transport the battery cell adsorbed by the first transfer adsorption unit 811 to the two first trays 822.

[0182] The second transfer single-axis manipulator 821 transports the first tray 822 with the battery cells placed thereon to the first glue coating detection unit 841 for UV glue coating detection; thereafter, the second transfer single-axis manipulator 821 transports the first tray 822 corresponding to the two battery cells detected by the first glue coating detection unit 841 to directly below the second transfer adsorption unit 823, and uses the second transfer lifting cylinder 824 to drive the second transfer adsorption unit 823 to descend, so that the second transfer adsorption unit 823 can adsorb the battery cells in the two first trays 822; then the second transfer lifting cylinder 824 cooperates with the third transfer lifting cylinder 824 to move the battery cells to the first tray 822. The single-axis manipulator 825 transfers the battery cells adsorbed by the second transfer and adsorption unit 823 to directly above the fourth transfer and adsorption unit 826, and the fourth transfer and adsorption unit 826 transfers the two second trays 827 to directly below the two battery cells; the second transfer lifting cylinder 824 controls the second transfer and adsorption unit 823 to descend, so that the second transfer and adsorption unit 823 can place the two battery cells it adsorbs in the second tray 827; the fourth transfer and adsorption unit 826 is then used to transfer the battery cells in the two trays to the second glue coating detection unit 842 for UV glue coating detection.

[0183] The fourth transfer single-axis manipulator 826 transports the second tray 827 corresponding to the two battery cells detected by the second glue coating detection unit 842 to directly below the third transfer and adsorption unit 831, and the third transfer lifting cylinder 832 controls the third transfer and adsorption unit 831 to descend so that the third transfer and adsorption unit 831 can adsorb the two battery cells in the second tray 827; the third transfer lifting cylinder 832 cooperates with the fifth transfer single-axis manipulator 933 to transport the battery cells adsorbed by the third transfer and adsorption unit 831 to the battery cell fixture 1, and then the clamping device 80 is activated to clamp the battery cell by the battery cell fixture 1, and the fixture reflux device 2 transports the battery cell to the next process.

[0184] Please refer again Figure 1 The above-mentioned glue coating and edge sealing production line also includes a hot melt adhesive coating device 6 located between the glue coating detection device 8 and the edge folding shaping device, which is used to coat the upper surface of the battery core skirt passing through the glue coating detection device 8 with hot melt adhesive. Figure 24 to Figure 26 As shown, the hot melt adhesive coating device 6 includes a coating frame 61, a first conveying section passes through the coating frame 61, and the hot melt adhesive coating device 6 also includes a coating component 62, a coating detection component 63 mounted on the top of the coating frame 61, and an upper coating light source 64 arranged above the battery cell and fastened to the coating frame 61.

[0185] In this embodiment, two coating components 62 are provided, which are respectively provided on both sides of the preset conveying direction. Specifically, the coating component 62 includes a coating bracket 621, a coating drive unit 622 mounted on the coating bracket 621, and a coating unit 623 connected to the coating drive unit 622; a lower coating light source 65 is provided below the battery cell, and the lower coating light source 65 and the upper coating light source 64 can respectively illuminate the upper and lower surfaces of the battery cell skirt to be coated, so as to facilitate the coating detection component 63 to obtain the image of the battery cell skirt through the built-in industrial camera, and then set the movement path of the coating drive unit 622. In this embodiment, the setting of the movement path of the coating detection component 63 and the coating drive unit 622 is more commonly used in the prior art, and will not be described in detail here.

[0186] More specifically, in order to prevent glue from dripping onto the lower coating light source 65 during the coating process, the coating assembly 62 further includes a lower coating light source driving unit 624 disposed on the coating bracket 621, which is used to drive the lower coating light source 65 to move horizontally in a direction perpendicular to the skirt of the battery cell to be coated. The lower light source coating driving unit 624 is a motor screw structure, which will not be described in detail here. When the industrial camera of the coating detection assembly 63 takes a picture of the battery cell skirt, the lower light source coating driving unit 624 drives the lower coating light source 65 to move to the bottom of the battery cell, and cooperates with the upper coating light source 64 to fill in the upper and lower surfaces of the battery cell skirt. After the photo is taken, the lower coating light source 65 moves to one side of the battery cell under the action of the lower light source coating driving unit 624, and then drives the coating unit 623 to coat the battery cell skirt through the coating driving unit 622. In this way, glue is prevented from dripping onto the lower coating light source 65 when coating the battery cell skirt.

[0187] Furthermore, the coating drive unit 622 in this embodiment includes a coating slide, a coating machine, a first coating drive unit, a second coating drive unit and a third coating drive unit mounted above the lower coating light source drive unit 624, wherein the coating machine is connected to the first coating drive unit, the first coating drive unit is arranged on the coating slide, and the first coating drive unit is used to drive the coating machine to rise and fall relative to the coating slide in the vertical direction; the second coating drive unit is used to drive the coating slide to move horizontally along a preset conveying direction, and the third coating drive unit is used to drive the second coating drive unit to move horizontally in a direction perpendicular to the skirt of the battery cell to be coated. With this structural design, the coating machine can be horizontally moved in a preset conveying direction, horizontally moved in a direction perpendicular to the skirt of the battery cell to be coated, and lifted and lowered in a vertical direction, thereby facilitating the coating machine 626 to flexibly coat the skirt of the battery cell.

[0188] In this embodiment, the first coating drive part is a cylinder, the second coating drive part is a motor gear rack structure, and the third coating drive part is a motor nut screw structure.

[0189] In this embodiment, in order to facilitate the adjustment of the coating angle of the coating machine 626, a coating arc groove 6221 is provided on one side of the pivot position of the coating slide 622, and a coating knob 66 ​​for driving the coating machine 626 to adjust the angle is inserted in the coating arc groove 6221. The coating knob 66 ​​is fastened to the coating machine 626 through a coating screw 67. Therefore, when adjusting the coating angle of the coating machine 626, it is only necessary to manually drive the coating screw 67 of the coating knob 66 ​​to slide along the coating arc groove 6234 and lock the coating knob 66.

[0190] When the battery fixture 1 carrying the battery cells moves between the two coating components 62 , the coating detection component 63 , under the supplementary lighting of the upper coating light source 64 and the lower coating light source 65 , clearly captures the image of the battery cells, and then provides support for the movement path of the coating drive unit 622 .

[0191] like Fig. 27 and Fig.28 As shown, the above-mentioned folding shaping device includes two folding shaping units and a folding shaping slide plate 94, wherein the two folding shaping units are both arranged on the folding shaping slide plate 94, and are horizontally distributed along the direction perpendicular to the skirt edge of the hot pressed battery core to be rolled, and each folding shaping unit forms a battery core channel, and each battery core channel is provided with a second conveying section 25. The folding shaping slide plate 94 can move horizontally along the direction perpendicular to the skirt edge of the hot pressed battery core to be rolled, so that the two second conveying sections 25 are alternately docked with the first conveying section to receive the battery core fixture 1 with the battery cores conveyed by the first conveying section.

[0192] The above-mentioned edge shaping device also includes an edge shaping driving unit 95, which is used to drive the edge shaping slide plate 94 to move horizontally in a direction perpendicular to the skirt of the hot pressed core to be rolled. The edge shaping driving unit can adopt a motor screw structure, a cylinder, etc., which will not be repeated here.

[0193] Each folding and shaping unit includes two rolling and hot pressing modules and two cold pressing modules arranged in sequence along a preset conveying direction, so that each folding and shaping unit can perform rolling and hot pressing treatment on two battery cells at the same time, and perform cold pressing treatment on two battery cells at the same time.

[0194] Each rolling hot pressing module includes rolling hot pressing units arranged on both sides of a preset conveying direction, and each rolling hot pressing unit includes a first rolling hot pressing bottom plate 9211, a second rolling hot pressing bottom plate 9212 that is lifted and lowered relative to the first rolling hot pressing bottom plate 9211, and a rolling hot pressing lifting drive 9213 that drives the second rolling hot pressing bottom plate 9212 to be lifted and lowered relative to the first rolling hot pressing bottom plate 9211. The rolling hot pressing lifting drive 9213 uses a cylinder or the like.

[0195] The rolling and hot pressing unit also includes a rolling part and a hot pressing part which are arranged on the second rolling and hot pressing bottom plate 9212 and are arranged opposite to each other up and down, wherein the rolling part is used to roll the cell skirt, and the hot pressing part is used to hot press the cell skirt processed by the rolling unit. The above-mentioned rolling and hot pressing unit also includes a rolling and hot pressing horizontal drive 927 that drives the rolling part and the hot pressing part to move horizontally perpendicular to the cell skirt to be rolled and hot pressed to move closer to or away from each other, and a rolling lifting drive that drives the rolling part to lift and lower. The above-mentioned rolling and hot pressing horizontal drive 927 and the rolling lifting drive both use cylinders.

[0196] In this embodiment, when the cell skirt is subjected to rolling and hot pressing treatment and cold pressing treatment, the cell fixture 1 is required to loosen the cell. Therefore, each rolling and hot pressing module is matched with two clamping devices 80, wherein the two rolling and hot pressing units correspond to the same clamping device 80, and the cold pressing module corresponds to one clamping device 80.

[0197] In this embodiment, the rolling part includes a rolling bracket 922 and a rolling roller 923 rotatably connected to the rolling bracket 922. The hot pressing part includes a hot pressing bracket 924 and a rolling hot pressing block 925 connected to the hot pressing bracket 924.
