[0030] Reference Figure 1 According to an embodiment of the present invention, the button battery filling port sealing automated welding equipment includes a frame 100 and a clamping and feeding mechanism 200. The clamping and feeding mechanism 200 includes a supporting plate 210, a moving component 220 and at least one clamping component 230 arranged along the left and right directions. The supporting plate 210 and the moving component 220 are installed on the frame 100. The clamping component 230 includes a first driving device 231, a first clamping member 232 and a second clamping member 233. The first clamping member 232 and the second clamping member 233 are arranged relative to each other in the front-to-back direction. The first driving device 231 is installed on the moving component 220. The first driving device 231 can drive the first clamping member 232 and the second clamping member 233 to move closer or farther relative to each other. The moving component 220 can drive the clamping component 230 to move left and right along the supporting plate 210. The clamping member 232 and the second clamping member 233 are arranged above the supporting plate 210 along the supporting plate 210. The supporting plate 210 is used to support the battery. When the first clamping member 232 and the second clamping member 233 are close to each other, the first clamping member 232, the second clamping member 233 and the supporting plate 210 are enclosed to form a clamping groove 240 for clamping the battery. All the clamping grooves 240 are arranged equidistantly in a straight line along the left and right directions; among them, the first loading mechanism 300 for conveying the battery to the clamping feeding mechanism 200, the second loading mechanism 400 for conveying the sealing member to the liquid filling port of the battery on the clamping feeding mechanism 200, the pre-welding mechanism 500 for pre-welding the battery with the corresponding sealing member and the full welding mechanism 600 for fully welding the battery with the corresponding sealing member are arranged in sequence along the supporting plate 210 and are at least partially located above the supporting plate 210.

[0031] During the operation of the clamping and feeding mechanism 200, the first clamping member 232 and the corresponding second clamping member 233 are first brought close to each other to clamp and position the battery on the supporting plate 210 in the clamping groove 240, and then the moving component 220 drives the entire clamping component 230 to move a certain distance toward the full welding mechanism 600, and then drives all batteries in the clamping groove 240 to move a certain distance along the supporting plate 210 toward the full welding mechanism 600. After the second feeding mechanism 400, the pre-welding mechanism 500 and the full welding mechanism 600 complete their respective tasks, the first clamping member 232 and the corresponding second clamping member 233 are separated from each other, and then the moving component 220 drives the clamping component 230 to move toward the first feeding mechanism 300. Reset, and continue to cycle in this way, so that the battery can be continuously transported forward along the supporting plate 210, and the battery is clamped and positioned by the clamping assembly 230 at the second loading mechanism 400, the pre-welding mechanism 500 and the full welding mechanism 600. Therefore, the button battery filling port sealing automated welding equipment can complete the battery transfer and transportation between various mechanisms and clamping and positioning of the battery at each mechanism by the clamping feeding mechanism 200, wherein the arrangement position of the clamping feeding mechanism 200 on the frame 100 and the arrangement position of the first loading mechanism 300, the second loading mechanism 400, the pre-welding mechanism 500 and the full welding mechanism 600 can overlap as much as possible, thereby making the equipment more compact, which is conducive to controlling the overall size of the equipment and reducing the footprint.

[0032] During the specific implementation process, the moving component 220 drives the clamping component 230 to move the same distance toward the full welding mechanism 600 each time. By precisely controlling the moving distance of the clamping component 230 each time, precise battery transportation can be achieved, so that the battery is accurately positioned when it is transported to the second loading mechanism 400 or the pre-welding mechanism 500, or the full welding mechanism 600. Therefore, the second loading mechanism 400, the pre-welding mechanism 500, or the full welding mechanism 600 does not need to repeatedly position the battery.

[0033] In some embodiments, in the above-mentioned clamping assembly 230, one first driving device 231 can be provided, and only one first clamping part 232 and second clamping part 233 need to be configured. At this time, the first clamping part 232 and the second clamping part 233 need to extend from the first loading mechanism 300 to the full welding mechanism 600. With the above-mentioned setting, the structure of the clamping assembly 230 is relatively simple and the assembly steps are relatively few. However, the first clamping part 232 and the second clamping part 233 are longer and heavier, and tools such as cranes are required to install the first clamping part 232 and the second clamping part 233, and the load on the first driving device 231 is relatively large.

[0034] According to some embodiments of the present invention, the first loading mechanism 300 is correspondingly provided with at least one group of clamping components 230, the second loading mechanism 400 is correspondingly provided with one group of clamping components 230, the pre-welding mechanism 500 is correspondingly provided with one group of clamping components 230, and the full welding mechanism 600 is correspondingly provided with at least one group of clamping components 230. Specifically, each first driving device 231 is provided with a first clamping part 232 and a second clamping part 233, and two adjacent first clamping parts 232 are independent of each other, and two adjacent second clamping parts 233 are also independent of each other. With the above-mentioned arrangement, the clamping assembly 230 completes the battery transportation and clamping positioning work through the cooperation of multiple first clamping parts 232 and multiple second clamping parts 233. At this time, although the clamping assembly 230 has more structures, each first clamping part 232 and each second clamping part 233 are short in length and light in weight, making assembly easier and more convenient. In addition, the load of each first driving device 231 is small, and it can more flexibly and quickly drive the first clamping part 232 and the corresponding second clamping part 233 to move closer or away from each other.

[0035] According to some embodiments of the present invention, each clamping groove 240 includes a first clamping groove 2321 and a second clamping groove 2331 that cooperate with each other. The first clamping groove 2321 is arranged on the first clamping part 232, and the second clamping groove 2331 is arranged on the second clamping part 233. The first clamping groove 2321 and the second clamping groove 2331 can be semicircular. At this time, the shape of the clamping groove 240 is more matched with the outer periphery of the button battery, thereby improving the clamping accuracy. However, the circular clamping groove 240 is usually only suitable for clamping batteries of one size.

[0036] It is conceivable that in other embodiments, the first clamping groove 2321 and the second clamping groove 2331 may also be V-shaped, so that the clamping groove 240 can clamp batteries of different sizes.

[0037] According to some embodiments of the present invention, the moving assembly 220 includes a second drive device 221 and a mounting platform 222. The mounting platform 222 is slidably mounted on the frame 100. The first drive device 231 is mounted on the mounting platform 222. The second drive device 221 is mounted on the frame 100. The second drive device 221 and the mounting platform 222 are connected by a screw rod 223. Through the above arrangement, the second drive device 221 drives the mounting platform 222 to move via the screw rod 223, which can drive the clamping assembly 230 to move precisely, thereby achieving precise battery transfer.

[0038] It is conceivable that in other embodiments, the above-mentioned moving component 220 can also be arranged in other ways. For example, the second driving device 221 and the screw rod 223 can be replaced by a hydraulic cylinder, and the mounting platform 222 can be driven by the hydraulic cylinder to move repeatedly.

[0039] According to some embodiments of the present invention, a blanking mechanism 700 is further included. A blanking section 211 is reserved at one end of the supporting plate 210 away from the first loading mechanism 300. The blanking mechanism 700 is used to remove the battery from the blanking section 211. Therefore, the battery after full welding can be pushed to the blanking section 211 by the clamping assembly 230, and then the battery on the blanking section 211 is removed by the blanking mechanism 700 to complete the blanking.

[0040] According to some embodiments of the present invention, two second loading mechanisms 400 are provided, and the pre-welding mechanism 500 has two resistance welding heads. Through the above arrangement, sealing parts can be placed on the liquid filling ports of the batteries in the two clamping grooves 240 at the same time, and the pre-welding work of the sealing parts of the two batteries can be completed at the same time, thereby improving production efficiency.

[0041] According to some embodiments of the present invention, the second feeding mechanism 400 includes a vibrating feeding device 410 and a second material transfer assembly 430. The vibrating feeding device 410 is used to supply sealing members to the second material transfer assembly 430, and the second material transfer assembly 430 is used to transport the sealing members to the clamping and feeding mechanism 200. Therefore, during the operation of the second feeding mechanism 400, the vibrating feeding device 410 supplies the stacked sealing members one by one to the second material transfer assembly 430, and then the second material transfer assembly 430 transports the sealing members to the corresponding battery filling ports on the clamping and feeding mechanism 200.

[0042] According to some embodiments of the present invention, the second feeding mechanism 400 further includes a cache positioning device 420, which is used to cache and position the sealing parts supplied by the vibration feeding device 410, and the second material moving assembly 430 can transport the sealing parts from the cache positioning device 420 to the clamping and feeding mechanism 200. During the operation of the second feeding mechanism 400, the vibration feeding device 410 supplies the sealing parts at a faster speed. The cache positioning device 420 can temporarily store and position the sealing parts supplied by the vibration feeding device 410, and then the second material moving assembly 430 transports the positioned sealing parts to the corresponding battery filling port on the clamping and feeding mechanism 200, so as to coordinate the feeding speed of the vibration feeding device 410 and the speed of transferring the battery by the clamping and feeding mechanism 200, and realize accurate feeding of the sealing parts, so as to avoid the problem that the position deviation of the sealing part cover at the battery filling port is too large, resulting in poor sealing between the sealing part and the battery after full welding.

[0043] According to some embodiments of the present invention, the cache positioning device 420 includes a third drive device 421, a positioning turntable 422, and a third material moving assembly 425. The third drive device 421 is mounted on the frame 100 and is used to drive the positioning turntable 422 to rotate. The positioning turntable 422 is provided with a plurality of cache positioning structures around its rotation axis. The cache positioning structures include a guide groove 4232 and a positioning groove 4231 provided on the bottom wall of the guide groove 4232. The sidewall of the guide groove 4232 is inclined. The third material moving assembly 425 is used to transport the sealing member from the discharge guide rail 411 of the vibrating loading device 410 to the positioning groove 4231 for positioning. The provision of the guide groove 4232 allows the third material moving assembly 425 to more smoothly transport the sealing member into the positioning groove 4231, and also facilitates the subsequent removal of the sealing member from the positioning groove 4231 by the second material moving assembly 430. Through the above-mentioned configuration, the cache positioning device 420 can efficiently and accurately position the sealing member.

[0044] According to some embodiments of the present invention, the cache positioning device 420 includes a cover plate 424, which is covered on the positioning turntable 422. The cover plate 424 and the positioning turntable 422 form an annular slide 4241. Each cache positioning structure includes a positioning column 423, the lower end of the positioning column 423 is attached to the positioning turntable 422, and the guide groove 4232 and the positioning groove 4231 are arranged on the corresponding positioning column 423. The cover plate 424 is provided with a first avoidance hole 4242 and a second avoidance hole 4243 connected to the slide 4241. A stop structure 426 is provided between the cover plate 424 and the cache positioning structure, and the first avoidance hole 4242 and the second avoidance hole 4243 are provided with a stop structure 426 electrically connected to the stop structure 426. The sensing device 4264, wherein the positioning turntable 422 can drive all the positioning posts 423 to slide in the slide 4241. When any guide groove 4232 moves to a position relative to the first avoidance hole 4242 or the second avoidance hole 4243, the sensing device 4264 triggers the stopping structure 426 to stop the positioning post 423, and the third material moving component 425 transports the sealing part from the second avoidance hole 4243 to the positioning groove 4231, and the second material moving component 430 receives the sealing part from the first avoidance hole 4242. During this process, the positioning turntable 422 does not need to stop rotating, which avoids the frequent start and stop of the third drive device 421 during the continuous operation of the second feeding mechanism 400, thereby ensuring the service life of the cache positioning device 420.

[0045] According to some embodiments of the present invention, the stopping structure 426 includes a stopping claw 4261 and a pushing cylinder 4262. The stopping claw 4261 is rotatably installed on the frame 100. A stopping groove is provided at one end of the stopping claw 4261. A reset elastic member 4263 is provided between the stopping claw 4261 and the frame 100. When the pushing cylinder 4262 abuts against and pushes the other end of the stopping claw 4261, one end of the stopping claw 4261 rotates toward the slide 4241 so that one of the positioning columns 423 is stuck in the stopping groove, thereby stopping the positioning column 423.

[0046] It is conceivable that, in other embodiments, the above-mentioned stop structure 426 may also be arranged in other ways. For example, the above-mentioned pushing cylinder 4262 may be replaced by a magnetic pushing device.

[0047] It is conceivable that, in other embodiments, the first loading mechanism 300 and the second loading mechanism 400 may also be arranged in other ways. For example, the first loading mechanism 300 and the second loading mechanism 400 may both include feeding robots.

[0048] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
