[0067] By adopting the above structure, the present invention only needs to put the carbon canister 110 and the non-woven fabric into the first carrier 220 and the unloading platform 300 respectively at the loading station, and then the assembling mechanism 400 can automatically assemble the non-woven fabric 120 into the carbon canister 110, and the turntable 210 can drive the first carrier 220 to flow through the welding mechanism 500 and the unloading mechanism 600 in sequence, the welding mechanism 500 can weld the carbon canister 110 and the non-woven fabric 120, and the unloading mechanism 600 can unload the welded carbon canister 110, thereby avoiding manual unloading and reducing labor, and as the turntable 210 rotates, the operator can continuously load the carbon canister 110 and the non-woven fabric 120 at the loading station, thereby improving loading efficiency and Welding efficiency; in addition, the first carrier 220 includes a carrier block 221, which is recessed inward from its top surface to form a first profiling groove 2211, and the first profiling groove 2211 is penetrated downward from its bottom to form a receiving hole 2212, and the position of the turntable 210 corresponding to the receiving hole 2212 is penetrated to form a first avoidance hole 211. When loading, the operator can directly insert the carbon canister 110 into the receiving hole 2212 and the first avoidance hole 211. Since the top support of the carbon canister 110 is positioned in the first profiling groove 2211, the position accuracy of the carbon canister 110 is high, and the stability of the carbon canister 110 during the circulation process can be effectively improved. There is no need to set up an additional complex clamping structure, and the installation is more convenient and efficient.

[0068] Furthermore, the carbon canister 110 includes a carbon canister body 111 and a flange 112. The flange 112 is arranged around the top periphery of the carbon canister body 111. The outer contour of the flange 112 matches the inner contour of the first profiling groove 2211. The flange 112 is suitable for supporting the bottom of the first profiling groove 2211. The carbon canister body 111 is recessed inward from its top to form a cavity 113 for accommodating the non-woven fabric 120. In this embodiment, the carbon canister body 111 is formed with two cavities 113. Of course, in other embodiments, the carbon canister body 111 may also form only one cavity 113.

[0069] Further, the first carrier 220 includes a bottom plate 222, the carrier block 221 is fixed on the bottom plate 222, the bottom plate 222 is detachably placed on the turntable 210, and the bottom plate 222 is provided with a receiving hole 2221 through the axial direction of the turntable 210 at the position corresponding to the receiving hole 2212 and the first avoidance hole 211, so as to be received between the receiving hole 2212 and the first avoidance hole 211. The inner contours of the receiving hole 2212, the first avoidance hole 211 and the receiving hole 2221 are preferably matched with the outer contour of the carbon canister body 111, so as to further improve the positioning accuracy and position reliability.

[0070] Specifically, the turntable mechanism 200 includes a positioning pin group and a toggle clamp group. The positioning pin group is suitable for positioning the bottom plate 222, and the toggle clamp group is suitable for tightening or loosening the bottom plate 222 in a positioning state. The positioning pin group is arranged on the turntable 210 and protrudes relative to the top surface of the turntable 210. The positioning pin group corresponds to the first carrier 220 one by one. The positioning pin group includes at least two positioning pins 230 fixed on the turntable 210. The bottom plate 222 is provided with pin holes 2222 corresponding to the positioning pins 230 one by one. When the bottom plate 222 is placed on the turntable 210, the positioning pins 230 are plugged into the pin holes 2222. The toggle clamp group includes at least two toggle clamps 240. The two toggle clamps 240 are arranged on both sides of the bottom plate 222 relatively. The two toggle clamps 240 are suitable for tightening or loosening the bottom plate 222. The toggle clamps 240 are existing structures, and the present invention will not be repeated here. Preferably, a handle 223 is provided on the bottom plate 222 to facilitate operators to disassemble, assemble and replace the first carrier 220 .

[0071] Furthermore, the turntable mechanism 200 includes a first base 250 and a cam divider 260, the cam divider 260 is fixed on the first base 250, the cam divider 260 includes a mounting flange 261 and a driving disk 262 rotatably mounted outside the mounting flange 261, the turntable 210 is coaxially fixed to the driving disk 262, and a second avoidance hole 212 is opened through the turntable 210 at the position corresponding to the mounting flange 261, and the unloading table 300 is fixed to the mounting flange 261 through the second avoidance hole 212, thereby making the unloading table 300 and the turntable 210 more compact, saving installation space, and the operator can also more conveniently load the non-woven fabric 120 to the unloading table 300 at the loading station.

[0072] Further, refer to Figures 2 to 4 As shown, the unloading platform 300 includes an unloading platform body 310 and a second carrier 320 disposed on the unloading platform body 310. The second carrier 320 is located near the loading station. The unloading platform 300 also includes a connecting piece 330 fixed to the bottom of the unloading platform body 310. The connecting piece 330 is fixed to the mounting flange 261 so that the clearance between the unloading platform body 310 and the turntable 210 is matched to prevent the unloading platform body 310 from hindering the rotation of the turntable 210. The second carrier 320 is recessed inward from its top surface to form a second profiling groove 321 for accommodating the non-woven fabric 120. The outer contour of the non-woven fabric 120 is matched with the inner contour of the second profiling groove 321, thereby effectively positioning the non-woven fabric 120, which is convenient for the assembly mechanism 400 to accurately grasp and assemble. Since the carbon canister 110 has two cavities 113 in this embodiment, the number of the second profiling grooves 321 is two, and they are respectively used to accommodate different non-woven fabrics.

[0073] Preferably, a positioning pin group and a toggle clamp group are also provided between the second carrier 320 and the material discharging platform 310, so as to realize the quick disassembly and replacement of the second carrier 320 and the material discharging platform 310. The specific structure can refer to the quick disassembly structure between the first carrier 220 and the turntable 210, and the present invention will not be repeated here. In addition, a sensor structure corresponding to the first carrier 220 can also be provided on the material discharging platform 310 to obtain the rotation state of the turntable 210 in real time.

[0074] Further, refer to Figure 1 and Figure 5 As shown, the assembly mechanism 400 is located above the unloading platform 300, and includes a first transverse moving module 410, a first lifting module 420 and a suction nozzle 430. The first transverse moving module 410 is transmission-connected to the first lifting module 420, and the suction nozzle 430 is transmission-connected to the first lifting module 420. The suction nozzle 430 is suitable for lowering the non-woven fabric 120 from the unloading position of the unloading platform 300 to the preset installation position in the carbon canister 110 under the drive of the first transverse moving module 410 and the first lifting module 420.

[0075] Specifically, the second carrier 320 and the first carrier 220 at the loading station are arranged at intervals along the radial direction of the turntable 210, the first transverse movement module 410 is suitable for driving the suction nozzle 430 to move back and forth between the first carrier 220 and the second carrier 320 along the radial direction of the turntable 210, and the first lifting module 420 is suitable for driving the suction nozzle 430 to rise and fall to suck the non-woven fabric 120 and load it into the carbon canister 110. Since there are two cavities 113 of the carbon canister 110 in this embodiment, there are two suction nozzles 430 accordingly, one of which corresponds to one of the second profiling grooves 321 and the cavity 113, and the other suction nozzle 430 corresponds to the other second profiling groove 321 and the cavity 113.

[0076] Preferably, the suction nozzle member 430 and the first lifting module 420 are connected by a first connecting frame 440, and the suction nozzle member 430 can be lifted and lowered on the first connecting frame 440 along the vertical direction. The assembly mechanism 400 also includes a lifting cylinder 450 arranged on the first connecting frame 440, and the lifting cylinder 450 is suitable for driving the suction nozzle member 430 to lift and lower. By adopting the above structure, during the process of assembling the non-woven fabric 120, the moving accuracy requirement for the first lifting module 420 is relatively low. When the non-woven fabric 120 needs to be grabbed, the first lifting module 420 only needs to drive the suction nozzle 430 down to a position adjacent to the second carrier 320, and then drive the suction nozzle 430 down through the lifting cylinder 450 to grab the non-woven fabric 120. When the non-woven fabric 120 needs to be loaded into the carbon canister 110, the first lifting module 420 only needs to drive the suction nozzle 430 down to a position adjacent to the bottom of the cavity 113, and then drive the suction nozzle 430 down through the lifting cylinder 450 to load the non-woven fabric 120 to the bottom of the cavity 113.

[0077] Further, refer to Figure 1 , Figure 6 and Figure 7 As shown, the turntable 210 has two welding stations, and there are two welding mechanisms 500, which are respectively arranged at different welding stations. When the first carrier 220 carrying the carbon canister 110 flows to one of the welding stations, the welding mechanism 500 at the welding station corresponds to one of the cavities 113 of the carbon canister 110. When the first carrier 220 carrying the carbon canister 110 flows to another welding station, the welding mechanism 500 at the welding station corresponds to another cavity 113 of the carbon canister 110. The two welding mechanisms 500 are suitable for extending into different cavities 113 to weld the non-woven fabric 120 to the carbon canister 110.

[0078] The welding mechanism 500 includes a mounting frame 510, a second lifting module 520 and a welding assembly 530. The second lifting module 520 is disposed on the mounting frame 510, and the welding assembly 530 is in transmission connection with the second lifting module 520. When the carbon canister 110 is in the welding station, the welding assembly 530 is located directly above the carbon canister 110. The welding assembly 530 is adapted to extend into the carbon canister 110 under the drive of the second lifting module 520, and weld the non-woven fabric 120 to the carbon canister 110.

[0079] The welding assembly 530 includes a second connecting frame 531 and a welding head 532 disposed on the second connecting frame 531. The second connecting frame 531 is fixed to the output end of the second lifting module 520. Preferably, a slide rail assembly 540 is provided between the second connecting frame 531 and the mounting frame 510. The slide rail assembly 540 is arranged in the vertical direction to guide the second connecting frame 531 to be lifted and lowered smoothly and reliably.

[0080] Preferably, the welding mechanism 500 also includes a first limit assembly 550 arranged on the mounting frame 510, and the first limit assembly 550 is located on the lifting path of the second connecting frame 531, and includes a first limit cylinder 551 and a limit seat 552. The first limit cylinder 551 and the limit seat 552 are both fixed on the mounting frame 510. The first limit cylinder 551 is a linear cylinder arranged in the horizontal direction. The limit seat 552 is formed with a support hole 5521 along the extension and retraction direction of the first limit cylinder 551, and the telescopic rod 5511 is penetrated in the support hole 5521 to support the telescopic rod 5511 and guide the telescopic rod 5511 to retract. When the telescopic rod 5511 of the first limiting cylinder 551 extends out of the supporting hole 5521 , it is located on the lifting path of the second connecting frame 531 . When the telescopic rod 5511 of the first limiting cylinder 551 contracts into the supporting hole 5521 , it is suitable to leave the lifting path of the second connecting frame 531 .

[0081] By setting the first limiting assembly 550, when the welding mechanism 500 is in a non-working state, the second connection frame 531 can be moved to the top of the first limiting assembly 550 under the drive of the second lifting module 520, and then the telescopic rod 5511 of the first limiting cylinder 551 can be extended to block the bottom of the second connecting frame 531, thereby playing the role of supporting the welding assembly 530, reducing the burden of the second lifting module 520, and improving the service life and position accuracy of the second lifting module 520. Moreover, since most of the telescopic rod 5511 of the first limiting cylinder 551 is supported in the supporting hole 5521, the first limiting cylinder 551 is not easy to be damaged and deformed when supporting the welding assembly 530. Preferably, in this embodiment, the number of the first limiting assemblies 550 is two, which are arranged on both sides of the second connecting frame 531 to cooperate with supporting the welding assembly 530.

[0082] Furthermore, during the welding process, the welding assembly 530 will continuously apply downward pressure to the carbon canister 110, and this pressure will be transmitted to the turntable 210. After long-term use, the connection between the turntable 210 and the cam divider 260 will be deformed, thereby affecting the service life of the turntable mechanism 200.

[0083] As a preferred embodiment, refer to Figure 1 , Figure 6 , Figures 8 to 10 As shown, the automatic welding equipment includes a support mechanism 700 arranged at the welding station, and the support mechanism 700 corresponds to the welding mechanism 500. The support mechanism 700 includes a pressure rod assembly 710 and a lifting assembly 720. The pressure rod assembly 710 is arranged on the welding assembly 530 and is suitable for descending with the welding assembly 530 and pushing against the top of the carbon canister 110. The lifting assembly 720 is arranged at the welding station and is located below the turntable 210. The lifting assembly 720 is suitable for lifting and supporting the carbon canister 110 at the welding station, so that the pressure will not be transmitted to the turntable 210 during the welding process, thereby improving the service life of the turntable 210, and the carbon canister 110 is limited between the pressure rod assembly 710 and the lifting assembly 720 in the vertical direction, and has good stability and will not affect the normal welding operation. In addition, when the welding assembly 530 moves downward to a preset position, the telescopic rod 5511 of the first limiting cylinder 551 can extend to the upper side of the second connecting frame 531, thereby limiting the welding assembly 530 upward to prevent the second lifting module 520 from being damaged when the lifting assembly 720 operates abnormally.

[0084] Furthermore, the pressure rod assembly 710 includes a pressure rod seat 711, a pressure rod 712 and a buffer spring 713. The pressure rod seat 711 is fixed to the welding assembly 530, specifically fixed to the second connecting frame 531. The pressure rod 712 includes a rod body 7121 and a pressure head 7122 connected to one end of the rod body 7121. The rod body 7121 can be movably inserted into the pressure rod seat 711 along the vertical direction. The pressure head 7122 protrudes relative to the periphery of the rod body 7121. The buffer spring 713 is sleeved outside the rod body 7121, and both ends are supported between the pressure head 7122 and the pressure rod seat 711. When the welding assembly 530 moves downward toward the carbon canister 110, the pressure head 7122 of the pressure rod 712 moves downward synchronously therewith and pushes against the top of the flange 112 of the carbon canister 110. Due to the action of the buffer spring 713, the pressure rod assembly 710 is not easy to damage the carbon canister 110, and the welding assembly 530 is not easy to be limited by the pressure rod assembly 710.

[0085] In this embodiment, a mounting hole 7111 is provided through the pressure rod seat 711 in the vertical direction, a linear bearing 714 is provided in the mounting hole 7111, and the pressure rod 712 is inserted into the linear bearing 714 to improve the smoothness of the lifting and lowering of the pressure rod 712. A limiting sleeve 715 is fixed at one end of the pressure rod 712 away from the pressure head 7122, and the limiting sleeve 715 protrudes relative to the periphery of the pressure rod 712 to prevent the pressure rod 712 from moving downward out of the linear bearing 714.

[0086] Furthermore, the lifting assembly 720 includes a second base 721, a lifting cylinder 722, a lifting frame 723 and a support seat 724. The lifting cylinder 722 is arranged on the second base 721, the lifting frame 723 can be arranged on the second base 721 to be raised and lowered in the vertical direction, and the support seat 724 is fixed on the lifting frame 723. The support seat 724 is suitable for being lifted upward under the drive of the lifting cylinder 722 to accommodate and support the bottom of the carbon canister 110.

[0087] The support seat 724 includes a seat body 7241, a support block 7242 and a positioning block 7243. The seat body 7241 is fixed on the lifting frame 723. The support block 7242 and the positioning block 7243 are both detachably connected to the seat body 7241. The support block 7242 is suitable for supporting the bottom of the carbon canister 110. There are multiple positioning blocks 7243, which are arranged around the peripheral side of the support block 7242. The multiple positioning blocks 7243 are suitable for cooperating with the horizontal limiting carbon canister 110 to improve the reliability during the support and lifting process. Preferably, in this embodiment, when the carbon canister 110 is supported on the first carrier 220, the flange 112 of the carbon canister 110 is recessed inwardly relative to the notch of the first profiling groove 2211, so that when the lifting assembly 720 lifts the carbon canister 110 to a preset height, the flange 112 is always positioned by the first profiling groove 2211, ensuring the position reliability of the carbon canister 110 during the lifting process.

[0088] However, with the lifting assembly 720 of the above structure, the lifting cylinder 722 is subjected to a large pressure and is easily damaged. As a preferred embodiment, the support mechanism 700 also includes a second limiting assembly 730 arranged on the second base 721. The second limiting assembly 730 includes a second limiting cylinder 731 and a limiting block 732 which is transmission-connected to the second limiting cylinder 731. The second limiting cylinder 731 is fixed to the second base 721. The limiting block 732 is slidably placed on the second base 721. The second limiting cylinder 731 is a linear cylinder arranged along the horizontal direction. When the second limiting cylinder 731 is extended, the limiting block 732 moves to the lifting path of the lifting frame 723. When the second limiting cylinder 731 is contracted, the limiting block 732 moves away from the telescopic path of the lifting frame 723. When the lifting cylinder 722 drives the lifting frame 723 to rise to the preset position, the second limiting cylinder 731 is suitable for driving the limiting block 732 to move to the lower side of the lifting frame 723 to support the lifting frame 723. Since the limiting block 732 is supported on the second base 721, when the lifting frame 723 is supported on the limiting block 732, the second limiting cylinder 731 is not easily deformed and damaged.

[0089] Preferably, in this embodiment, the number of the second limiting components 730 is two groups, and they are relatively arranged on both sides of the lifting frame 723 to cooperate with the supporting lifting frame 723 to further improve the reliability of the support.

[0090] Further, refer to Figure 1 and Fig.11 As shown, the unloading mechanism 600 includes a second transverse moving module 610, a third transverse moving module 620, a third lifting module 630 and a clamping assembly 640. The third transverse moving module 620 is connected to the second transverse moving module 610 by transmission, the third lifting module 630 is connected to the third transverse moving module 620 by transmission, and the clamping assembly 640 is connected to the third lifting module 630 by transmission. The moving directions of the second transverse moving module 610 and the third transverse moving module 620 are both horizontal and perpendicular to each other. When the carbon canister 110 flows to the unloading station, the clamping assembly 640 is suitable for moving to the carbon canister 110 under the drive of the above modules to clamp the carbon canister 110 and move it to a preset position. The clamping assembly 640 is a conventional clamping claw structure. Preferably, the carrier block 221 is recessed inward from its top surface to form an avoidance portion 2213. The avoidance portion 2213 is a through structure in the clamping direction of the clamping assembly 640. The avoidance portion 2213 can drive part of the side wall of the carbon canister 110 to be exposed, and the clamping assembly 640 can clamp the carbon canister 110 through the avoidance portion 2213.

[0091] Furthermore, the automatic welding equipment further includes a conveyor line 800 arranged adjacent to the unloading mechanism 600, and there are two conveyor lines 800. The unloading mechanism 600 can transfer the products with qualified welding to one of the conveyor lines 800, and transfer the products with unqualified welding to the other conveyor line 800. Preferably, the two conveyor lines 800 are stacked up and down, and the conveying directions are parallel, so as to save installation space, and the input ends of the two conveyor lines 800 are staggered in their conveying directions, so as to ensure that the unloading mechanism 600 can unload the carbon canister 110 to different input ends.

[0092] The working process of the automatic welding equipment of the present invention is as follows: the turntable 210 transfers the empty first carrier 220 to the loading station, the operator puts the carbon canister 110 into the first carrier 220 at the loading station, and puts the non-woven fabric 120 into the second carrier 320; the assembly mechanism 400 grabs the non-woven fabric 120 and loads the non-woven fabric 120 into the bottom of the carbon canister 110; then the turntable 210 drives the carbon canister 110 to transfer to one of the welding stations to weld the non-woven fabric 120 in one of the cavities 113 of the carbon canister 110. During this process, the lifting assembly 720 is lifted upward to lift and support the carbon canister 110, and then the welding assembly 530 and the pressure rod assembly 710 are synchronously moved downward to weld. The connecting assembly 530 extends into the interior of the carbon canister 110 to weld the non-woven fabric 120, and the pressure rod assembly 710 presses against the top of the carbon canister 110; after welding is completed, the welding mechanism 500 and the lifting assembly 720 are reset, and the turntable 210 drives the carbon canister 110 to continue to flow to another welding station to weld the non-woven fabric 120 of another cavity 113 of the carbon canister 110; after welding is completed, the turntable 210 drives the carbon canister 110 to flow to the unloading station, if the carbon canister 110 is welded qualified, the unloading mechanism 600 unloads the qualified carbon canister 110 to one of the conveyor lines 800, if the carbon canister 110 is welded unqualified, the unloading mechanism 600 unloads the carbon canister 110 to another conveyor line 800.
