[0030] Reference Figure 1 According to an embodiment of the present invention, the button battery filling port sealing automatic 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 assembly 220 and at least one clamping assembly 230 arranged along the left and right directions. The supporting plate 210 and the moving assembly 220 are installed on the frame 100. The clamping assembly 230 includes a first driving device 231, a first clamping piece 232 and a second clamping piece 233. The first clamping piece 232 and the second clamping piece 233 are arranged relatively in the front-back direction. The first driving device 231 is installed on the moving assembly 220. The first driving device 231 can drive the first clamping piece 232 and the second clamping piece 233 to move relatively close to or away from each other. The moving assembly 220 can drive the clamping assembly 230 to move left and right along the supporting plate 210. The clamp 232 and the second clamp 233 are arranged above the supporting plate 210 along the supporting plate 210, and the supporting plate 210 is used to support the battery. When the first clamp 232 and the second clamp 233 are close to each other, the first clamp 232, the second clamp 233 and the supporting plate 210 are enclosed to form a clamping groove 240 for clamping the battery, and all the clamping grooves 240 are arranged equidistantly in a straight line along the left and right directions; wherein, a first loading mechanism 300 for conveying the battery to the clamping feeding mechanism 200, a second loading mechanism 400 for conveying the sealing member to the injection port of the battery on the clamping feeding mechanism 200, a pre-welding mechanism 500 for pre-welding the battery with the corresponding sealing member, and a 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 assembly 220 drives the entire clamping assembly 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 assembly 220 drives the clamping assembly 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 feeding 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 and feeding mechanism 200, wherein the arrangement position of the clamping and feeding mechanism 200 on the frame 100 can overlap with the arrangement positions of the first feeding mechanism 300, the second feeding mechanism 400, the pre-welding mechanism 500 and the full welding mechanism 600 as much as possible, thereby making the equipment more compact, which is beneficial 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 full welding mechanism 600 by the same distance each time. By precisely controlling the moving distance of the clamping component 230 each time, accurate 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, and the full welding mechanism 600 do 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 set, and only one first clamping member 232 and second clamping member 233 are required. At this time, the first clamping member 232 and the second clamping member 233 need to extend from the first feeding 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 member 232 and the second clamping member 233 are relatively long and heavy, and tools such as cranes are required to install the first clamping member 232 and the second clamping member 233, and the load of the first driving device 231 is relatively large.

[0034] According to some embodiments of the present invention, the first feeding mechanism 300 is correspondingly provided with at least one group of clamping assemblies 230, the second feeding mechanism 400 is correspondingly provided with one group of clamping assemblies 230, the pre-welding mechanism 500 is correspondingly provided with one group of clamping assemblies 230, and the full welding mechanism 600 is correspondingly provided with at least one group of clamping assemblies 230. Specifically, each first driving device 231 is provided with a first clamping component 232 and a second clamping component 233, and two adjacent first clamping components 232 are independent of each other, and two adjacent second clamping components 233 are also independent of each other. With the above 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, and assembly is easier and easier. In addition, the load of each first driving device 231 is small, and the first clamping part 232 and the corresponding second clamping part 233 can be driven more flexibly and quickly to move closer or farther 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 member 232, and the second clamping groove 2331 is arranged on the second clamping member 233, wherein 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 circumference 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 driving device 221 and a mounting platform 222, the mounting platform 222 can be slidably mounted on the frame 100, the first driving device 231 is mounted on the mounting platform 222, the second driving device 221 is mounted on the frame 100, and the second driving device 221 and the mounting platform 222 are connected by a screw rod 223. Through the above arrangement, the second driving device 221 drives the mounting platform 222 to move through the screw rod 223, which can drive the clamping assembly 230 to move accurately, thereby realizing accurate 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 material unloading mechanism 700 is further included. A material unloading section 211 is reserved at one end of the supporting plate 210 away from the first loading mechanism 300. The material unloading mechanism 700 is used to remove the battery on the material unloading section 211. Therefore, the battery after full welding can be pushed to the material unloading section 211 by the clamping assembly 230, and then the battery on the material unloading section 211 is removed by the material unloading mechanism 700 to complete the unloading.

[0040] According to some embodiments of the present invention, two second feeding 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 moving assembly 430, wherein the vibrating feeding device 410 is used to supply sealing parts to the second material moving assembly 430, and the second material moving assembly 430 is used to convey the sealing parts to the clamping and feeding mechanism 200. Thus, during the operation of the second feeding mechanism 400, the vibrating feeding device 410 supplies the stacked sealing parts to the second material moving assembly 430 one by one, and then the second material moving assembly 430 conveys the sealing parts to the corresponding battery injection port 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 member supplied by the vibration feeding device 410, and the second material moving assembly 430 can transport the sealing member from the cache positioning device 420 to the clamping feeding mechanism 200. During the operation of the second feeding mechanism 400, the vibration feeding device 410 supplies the sealing member at a faster speed, and the cache positioning device 420 can temporarily store and position the sealing member supplied by the vibration feeding device 410, and then the second material moving assembly 430 transports the positioned sealing member to the corresponding battery injection port on the clamping 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 feeding mechanism 200, and realize accurate feeding of the sealing member, so as to avoid the problem that the position deviation of the sealing member cover at the battery injection port is too large, resulting in poor sealing between the sealing member and the battery after full welding.

[0043] According to some embodiments of the present invention, the cache positioning device 420 includes a third driving device 421, a positioning turntable 422 and a third material moving assembly 425. The third driving device 421 is installed on the frame 100. The third driving device 421 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 structure includes a guide groove 4232 and a positioning groove 4231 provided on the bottom wall of the guide groove 4232. The side wall 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 vibration feeding device 410 to the positioning groove 4231 for positioning. The provision of the guide groove 4232 can make the third material moving assembly 425 more smoothly deliver the sealing member into the positioning groove 4231, and also facilitate the subsequent second material moving assembly 430 to take out the sealing member from the positioning groove 4231. Through the above-mentioned arrangement, 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, and the cover plate 424 and the positioning turntable 422 are enclosed to form an annular slideway 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, and the cover plate 424 is provided with a first avoidance hole 4242 and a second avoidance hole 4243 connected to the slideway 4241, and a stop structure 426 is arranged 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 guide hole electrically connected to the stop structure 426. The sensing device 4264, wherein the positioning turntable 422 can drive all the positioning columns 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 column 423, and the third material moving component 425 transports the sealing piece from the second avoidance hole 4243 to the positioning groove 4231, and the second material moving component 430 receives the sealing piece from the first avoidance hole 4242. During this process, the positioning turntable 422 does not need to stop rotating, thereby avoiding the frequent start and stop of the third driving 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-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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 knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
