Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production equipment, in particular to a lithium battery cover assembly gluing device. Background Art

[0002] In the production process of lithium batteries, it is necessary to perform gluing and packaging operations on lithium batteries, which involves the gluing operation of the lithium battery cover group. It is necessary to stick the sticker to the gluing part on the lithium battery cover group and keep the sticker and the gluing part completely in contact with each other to ensure the sticker sticking effect. However, in the traditional cover group gluing operation, because the gluing part on the lithium battery cover group is too small, the corresponding sticker used is also too small, too light, and too thin. The position of the sticker is easily offset during the sticker feeding process, which will cause the center of the sticker and the center of the corresponding gluing part to be difficult to align when the lithium battery cover group is gluing. The sticker cannot be completely in contact with the gluing part, resulting in poor sticker sticking effect and affecting the yield rate of gluing. Therefore, in traditional operations, rework and re-gluing are often required, which affects the efficiency of the lithium battery cover group gluing operation and increases production costs.

[0030] like Figures 1 to 6 As shown, a gluing device for lithium battery cover assembly of this embodiment includes a loading mechanism 100, a gluing feeding mechanism 200, a material taking mechanism 300 and a visual recognition mechanism 400. The loading mechanism 100 is provided with a plurality of placement slots 111 for placing lithium battery cover assembly 600; the gluing feeding mechanism 200 is arranged on one side of the loading mechanism 100, and the gluing feeding mechanism 200 includes a gluing conveying assembly 210 and a feeding platform 220. The gluing conveying assembly 210 includes a discharge reel 211 and a reel 212. The feeding platform 220 is disposed between the discharge reel 211 and the reel 212. The adhesive tape 500 passes through the discharge reel 211, the reel 212 in sequence. A feeding platform 220 and a winding shaft 212; a material picking mechanism 300 is arranged on one side of the loading mechanism 100 and the adhesive feeding mechanism 200, the material picking mechanism 300 includes a material picking robot 310, and the placement slot 111 and the feeding platform 220 are located within the movement range of the material picking robot 310; a visual recognition mechanism 400 is arranged on one side of the adhesive feeding mechanism 200, the visual recognition mechanism 400 includes a photographing component 410 arranged toward the feeding platform 220, and the photographing component 410 takes a photograph of the position of the sticker 510 of the tape 500 on the feeding platform 220.

[0031] Among them, the photographing component 410, the glue feeding mechanism 200 and the picking mechanism 300 are all connected to the controller (not shown) to receive the position information of the sticker 510 photographed by the photographing component 410 through the controller, and control the glue feeding mechanism 200 to feed and control the picking mechanism 300 to grab the sticker 510.

[0032] In this embodiment, the tape 500 is unwound from the unwinding shaft 211 and conveyed to the feeding platform 220 by feeding through the unwinding shaft 211, and then the sticker 510 on the tape 500 is grabbed by the picking mechanism 300 and adhered to the lithium battery cover group 600 of the loading mechanism 100 to complete the gluing operation, and then the release paper 520 is rolled up from the feeding platform 220 to the winding shaft 212. Specifically, when the sticker 510 is conveyed to the feeding platform 220 along with the tape 500, the sticker 510 located on the feeding platform 220 is photographed by the photographing component 410, and the position information of the sticker 510 is fed back to the picking mechanism 300, so that the picking mechanism 300 controls the robot arm to accurately pick up the sticker 510 according to the position information of the sticker 510, and then the sticker 510 is affixed to the lithium battery cover group 600 placed in the placement groove 111, and the center position of the sticker 510 is aligned and affixed with the center of the adhesive part 610 of the lithium battery cover group 600, so that the sticker 510 can be completely affixed to the adhesive part 610, thereby ensuring the adhesive effect of the sticker 510, improving the efficiency of the adhesive operation, and reducing the production cost.

[0033] In actual operation, the visual recognition mechanism 400 also includes an adjustment component 420, and the camera component 410 can be movably connected to the adjustment component 420, so as to flexibly adjust the camera position of the camera component 410, and ensure that the camera component 410 can accurately capture the sticker 510 located on the feeding platform 220. Specifically, the adjustment component 420 includes an adjustment base 421, and an adjustment rod 422 is provided on the adjustment base 421. The camera component 410 includes a connecting bracket 412, a sliding plate 413 and a visual camera 411. The visual camera 411 is fixed on the sliding plate 413, and the sliding plate 413 is slidably connected to the connecting bracket 412. At the same time, the connecting bracket 412 is slidably connected to the adjustment rod 422. Among them, the sliding plate 413 slides on the connecting bracket 412 to approach or move away from the adjustment rod 422, and the connecting bracket 412 rotates around the central axis of the adjustment rod 422 on the adjustment rod 422, or moves along the central axis direction of the adjustment rod 422. Through the above-mentioned movable connection design, the visual camera 411 can be moved in multiple directions so as to clearly and accurately capture the image of the sticker 510 and ensure the accuracy of the positioning information.

[0034] In one embodiment, the material picking robot 310 includes a material picking assembly 311, and the material picking assembly 311 includes a plurality of material picking heads 3111 and a first driving member 3113, and the first driving member 3113 is connected to the material picking head 3111 in a transmission manner to control the material picking head 3111 to grab or release the sticker 510. The plurality of material picking heads 3111 are connected to the plurality of first driving members 3113 in a one-to-one correspondence, so that a single material picking head 3111 is individually controlled by a single first driving member 3113, so that when the sticker 510 is grabbed, each material picking head 3111 can perform an individual grabbing operation on the sticker 510, so that when each material picking head 3111 is driven by the material picking robot 310 to align with the corresponding sticker 510, the material picking head 3111 is correspondingly controlled to grab the sticker 510, so that each material picking head 3111 can accurately grab the corresponding sticker 510.

[0035] Specifically, a suction cup 3112 is provided on the material taking head 3111, and the sticker 510 is sucked by the suction cup 3112 to complete the material taking operation of the sticker 510, and when gluing, the suction cup 3112 is driven to stick the sucked sticker 510 on the gluing part 610 of the lithium battery cover assembly 600, and then the suction cup 3112 is driven to stop adsorption. Among them, the first driving member 3113 includes a single control air pipe 3114 connected to the suction cup 3112, which is used to control the suction of each suction cup 3112 on the material taking head 3111 individually. Of course, outside of this embodiment, the grabbing of the sticker 510 is not limited to the suction method of the suction cup 3112 in this embodiment, and other grabbing methods can also be used. As long as the sticker 510 can be grabbed and stuck on the corresponding gluing part 610, such designs belong to the protection scope of the utility model.

[0036] In one embodiment, the material picking assembly 311 further includes a plurality of second driving members 3115, which are connected to the plurality of material picking heads 3111 in a one-to-one transmission manner, and the second driving members 3115 drive the material picking heads 3111 to move closer to or away from the feeding platform 220 or the placement slot 111, and a single material picking head 3111 is driven to move independently by a single second driving member 3115. Specifically, during the material picking and gluing operation, when the corresponding positions of the stickers 510 on the tape 500 are not exactly the same, the material picking head 3111 can be driven independently by the second driving member 3115 toward the corresponding sticker 510, and then driven to grab by the corresponding first driving member 3113, and then driven by the material picking robot 310 to align the other material picking heads 3111 with the corresponding grabbed stickers 510, and then driven by the corresponding second driving member 3115 to move toward the corresponding sticker 510.

[0037] For the above-mentioned drive control, in actual operation, if there are several material taking heads 3111 aligned with the positions of several corresponding stickers 510 to be grabbed, then the corresponding second driving member 3115 can be used to drive these parts of the material taking heads 3111 to move toward the corresponding stickers 510 at the same time, and the corresponding first driving member 3113 can be used to drive the grabbing, and then the other material taking heads 3111 can be driven to grab in turn. Through such a design, each material taking head 3111 can be driven individually, which can effectively ensure that each material taking head 3111 can accurately grab the corresponding sticker 510, and effectively ensure the accuracy of the final glue sticking. And in the case where multiple material taking heads 3111 are aligned with the corresponding stickers 510, these parts of the material taking heads 3111 can be driven to grab at the same time, without being restricted to grabbing in sequence by a single material taking head 3111, and the control operation is more flexible, and it is conducive to improving the efficiency of grabbing and the efficiency of glue sticking.

[0038] In one embodiment, the material taking assembly 311 further includes a connecting plate 3116, and the material taking head 3111, the first driving member 3113 and the second driving member 3115 are arranged on the connecting plate 3116. The connecting plate 3116 is provided with a slide rail 3117 and a slider 3118 slidably arranged on the slide rail 3117, the material taking head 3111 is fixed on the slider 3118, and the second driving member 3115 is in transmission connection with the slider 3118 to drive the slider 3118 to slide on the slide rail 3117, so that the slider 3118 drives the material taking head 3111 to move close to or away from the feeding platform 220 or the placement slot 111.

[0039] In one embodiment, the material picking mechanism 300 also includes a robot body 320, and the material picking robot 310 is movably arranged on the robot body 320. The material picking robot 310 also includes a robot arm 312, one end of the robot arm 312 is connected to the robot body 320, and the other end of the robot arm 312 is connected to the connecting plate 3116. The connecting plate 3116 is driven to move by the robot arm 312, that is, the material picking assembly 311 is driven to move as a whole by the loading and unloading arm, so as to realize the grabbing of the sticker 510 and the glue sticking operation of the lithium battery cover group 600 placed on the placement slot 111.

[0040] In one embodiment, the adhesive feeding mechanism 200 includes a mounting bracket 230, and the adhesive conveying assembly 210 and the feeding platform 220 are mounted and fixed on the mounting bracket 230. The adhesive conveying assembly 210 includes a feeding drive member, which is in transmission connection with the unwinding shaft 211 and / or the rewinding shaft 212 to drive the unwinding shaft 211 and / or the rewinding shaft 212 to rotate, so as to realize the conveyance of the adhesive tape 500. In this embodiment, the feeding drive component includes a feeding motor 213, the feeding motor 213 and the winding shaft 212 are installed on one side of the mounting bracket 230, the output shaft of the feeding motor 213 passes through the mounting bracket 230 and is arranged on the other side of the mounting bracket 230, the output shaft of the feeding motor 213 is transmission-connected with a driving wheel 214, and the winding shaft 212 passes through one side of the mounting bracket 230 and is provided with a driven wheel 215, the driving wheel 214 is transmission-connected with the driven wheel 215 through a synchronous belt 216, so that the winding shaft 212 is driven to rotate synchronously by the feeding motor 213 to pull the tape 500, thereby providing conveying power for the tape 500, and winding up and recycling the release paper 520 after the sticker 510 is removed.

[0041] In one embodiment, the adhesive feeding mechanism 200 further includes a sensor 240, which is disposed on the feeding platform 220 for sensing the position of the sticker 510 to determine whether the sticker 510 is smoothly delivered to the feeding platform 220. The sensor 240 is connected to the feeding drive and the visual recognition mechanism 400. When the sensor 240 does not sense the sticker 510, the feeding drive continues to drive the conveyance of the adhesive tape 500 until the sensor 240 senses that the sticker 510 is smoothly delivered to the feeding platform 220, and then feeds back the corresponding information to the feeding drive and the visual recognition mechanism 400. At this time, the feeding drive stops conveying the adhesive tape 500, and the visual recognition mechanism 400 starts and takes photos of the sticker 510 placed on the feeding platform 220. Through the sensor 240, it is possible to accurately identify whether the sticker 510 is smoothly fed to the feeding platform 220, and through the sensing and feedback of the sensor 240, the feeding automation and photo automation operations are realized, which is conducive to improving the automation degree of the overall equipment and the overall operation efficiency.

[0042] In actual operation, when the position of the sticker 510 is sensed by the sensor 240, the feeding drive member still drives the tape 500 to be transported forward for a distance, so that the sticker 510 enters the photographing and recognition range of the visual recognition mechanism 400. Specifically, the tape 500 enters from the upper part of the first side of the feeding platform 220 to the second side of the feeding platform 220, and is conveyed from the lower part of the second side of the feeding platform 220 back to the direction of the first side of the feeding platform 220, so that the sticker 510 and the release paper 520 are separated at the edge of the second side of the feeding platform 220, which facilitates the operation of the picking mechanism 300 to pick up the sticker 510.

[0043] In one embodiment, the loading mechanism 100 includes a loading turntable 110, and the placement grooves 111 are evenly arranged around the loading turntable 110. The loading mechanism 100 is adjacent to the side of the glue feeding mechanism 200. A glue sticking station is provided. When the loading turntable 110 rotates, a plurality of lithium battery cover groups 600 placed in the placement grooves 111 enter the glue sticking station in turn, and the lithium battery cover groups 600 are placed in a plurality of placement grooves 111 through external loading equipment, and then the lithium battery cover groups 600 are loaded in turn through the loading turntable 110.

[0044] Among them, the lithium battery cover group 600 is provided with a plurality of glue sticking parts 610 arranged side by side, and the arrangement direction of the plurality of glue sticking parts 610 on the lithium battery cover group 600 located at the glue sticking station is parallel to the conveying direction of the tape 500 on the feeding platform 220. The plurality of stickers 510 are arranged side by side on the tape 500, and the arrangement direction of the plurality of stickers 510 is perpendicular to the arrangement direction of the glue sticking parts 610, so that when the material picking robot 310 performs the glue sticking operation, it first aligns and grabs the plurality of material picking heads 3111 arranged side by side with the stickers 510, and then controls the entire row of material picking heads 3111 to rotate synchronously by 90° through the material picking robot, and at this time, the plurality of material picking heads 3111 grabbing the stickers 510 correspond one to one with the plurality of glue sticking parts 610. In actual operation, the material picking and gluing are performed by right-angle rotation of 90° respectively. The operation and corresponding control design are relatively simple, and the positions of the loading mechanism 100 and the gluing feeding mechanism 200 are arranged conveniently and compactly, which is conducive to improving the space utilization rate of the workshop.

[0045] Specifically, the feeding mechanism 100 also includes a feeding bracket 120 and a feeding drive 130. The feeding mechanism 100 is rotatably set on the feeding bracket 120. The feeding drive 130 is transmission-connected to the feeding turntable 110 to drive the feeding turntable 110 to rotate on the feeding bracket 120, so as to realize the rotational loading and unloading of the lithium battery stamp, and the operation is simple and convenient.
