[0032] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] See also Figures 1 to 5 A production line for electrode powder cleaning, electric welding, gluing and kneading comprises a feeding section 10, a processing section 20 and a discharging section 30, wherein the feeding section 10 and the discharging section 30 are respectively located on both sides of the processing section 20; the processing section 20 comprises a cabinet 200, and a processing turntable 210, a feeding and transporting module 220, a powder cleaning mechanism 230, a tab conveying and cutting mechanism 240, a tab welding mechanism 250, a tab gluing mechanism 260, a discharging and transporting module 270 and a conveyor line 280 arranged on the cabinet 200; The loading and transporting module 220, the powder cleaning mechanism 230, the tab conveying and cutting mechanism 240, the tab welding mechanism 250, the tab gluing mechanism 260 and the unloading and transporting module 270 are respectively arranged around the production turntable 210, and a number of jigs 211 are distributed at intervals on the production turntable 210; the loading and transporting module 220 travels back and forth between the loading section 10 and the jig 211, and the unloading and transporting module 270 travels back and forth between the jig 211 and the conveyor line 280, and the conveyor line 280 is connected to the unloading section 30.

[0036] Specifically, in this embodiment, when the electrode is prepared and produced, the electrode is automatically loaded and transported by the loading section 10. After loading to the set position, the electrode of the loading section 10 is sucked and transported to the fixture 211 of the film turntable 210 by the loading and transporting module 220 of the film turntable 20, and the film turntable 210 rotates with the fixture 211. When it rotates to the powder cleaning mechanism 230, the powder cleaning mechanism 230 performs ultrasonic high-frequency vibration to perform welding on the electrode. The powder is cleaned by vibration to expose the original base material of the electrode. After the powder is cleaned, the powder will be extracted by a vacuum pipe to improve the subsequent welding quality of the electrode and the electrode. After the electrode is cleaned, the film turntable 210 and the fixture 211 are rotated to the electrode conveying and cutting mechanism 240. The electrode conveying and cutting mechanism 240 automatically conveys the electrode and cuts the electrode into a set size. After cutting, it is sucked and placed in the fixture 211 to cooperate with the electrode in the fixture 211. After the tab is placed on the jig 211, the production turntable 210 continues to rotate with the jig 211 to the tab welding mechanism 250, and the tab and the pole piece in the jig 211 are welded by the tab welding mechanism 250. After welding, the production turntable 210 rotates with the jig 211 to the tab gluing mechanism 260, and the tab gluing mechanism 260 automatically conveys the tape and cuts it into a set size. After cutting, the tape is pasted to the tab and the tab and the pole piece are welded. On the upper and lower surfaces, when the glue is completed, the film turntable 210 rotates with the jig 211 to the unloading and transporting module 270, and the electrode is sucked and transported to the conveyor line 280 by the unloading and transporting module 270. The electrode is transported by the conveyor line 280 and transported to the unloading section 30, and the electrode is first kneaded and shaped by the unloading section 30, and then stacked and unloaded in sequence after shaping, finally realizing the automated preparation and production of the electrode, thereby improving the production efficiency and production quality of the electrode.

[0037] Of course, in order to ensure the production quality of the electrode, in this embodiment, a CCD detection mechanism 290 is also provided on the side of the conveyor line 280. The welding between the electrode tab and the electrode and the gluing of the electrode tab are detected by the CCD detection mechanism 290, thereby ensuring the quality of the electrode production.

[0038] In addition, when preparing and producing the electrode sheet, the electrode sheet needs to be welded with four groups of electrode tabs. Therefore, in the production line of this embodiment, the electrode tab conveying and cutting mechanism 240 can simultaneously convey and cut four groups of electrode tabs, and absorb and place the four groups of electrode tabs into the jig 211 to cooperate with the electrode sheet. Similarly, the electrode tab gluing mechanism 260 is also provided with four groups, and is arranged in pairs. By simultaneously loading four groups of electrode tabs and simultaneously sticking four groups of tapes, production needs can be met. Of course, the number of layouts can be set according to actual production needs and is not limited here.

[0039] The loading and transporting module 220 and the unloading and transporting module 270 in this embodiment are PPU manipulators, and the powder cleaning mechanism 230 and the tab welding mechanism 250 are all existing technologies, so they will not be described in detail here.

[0040] See also Figure 2 and Figure 12 In order to realize the automatic transportation of the electrode pieces, the loading section 10 in this embodiment includes a feeding line 100, a loading rotation unit 110 and an inlet assembly line 120. The loading rotation unit 110 is located between the feeding line 100 and the inlet assembly line 120, and the loading rotation unit 110 can rotate 180° to suck the electrode pieces on the feeding line 100 to the inlet assembly line 120. The tail end of the inlet assembly line 120 cooperates with the loading and handling module 220.

[0041] The feeding line 100 transports the feeding frame full of electrode pieces. When the feeding frame is transported to the set position, the loading rotary unit 110 will move downward to absorb the electrode pieces in the feeding frame. After absorption, it will be rotated 180° so that the absorbed electrode pieces are above the feeding line 120. The loading rotary unit 110 then places the electrode pieces on the feeding line 120 for transportation, thereby realizing automatic transmission and loading of the electrode pieces and improving the production efficiency of electrode preparation. The loading rotary unit 110 is a prior art, which is composed of a rotary cylinder / rotary motor, a lifting cylinder and an adsorption head, so it will not be described in detail here.

[0042] See also Figures 6 to 9 In order to realize the automatic conveying, cutting and loading of the tabs, the tab conveying and cutting mechanism in this embodiment includes a material tray 241, a conveying channel 242, a conveying drive unit 243, a positioning unit 244, a cutting unit 245 and a transport unit 246. The material tray 241 and the cutting unit 245 are respectively located at the two ends of the conveying channel 242. The material tray 241 is used to install the tab coil, the conveying drive unit 243 drives the tab to be conveyed along the conveying channel 242, and the cutting unit 245 is used to cut the conveyed tab. During cutting, the positioning unit 244 presses down and positions the conveyed tab, and the transport unit 246 transports the cut tab to the jig 211.

[0043] When loading the tabs, the tab coils are mounted on the tray 241, and the starting end of the tabs is passed through the conveying channel 242. The tabs in the conveying channel 242 are conveyed forward by the conveying drive unit 243, and pass through the positioning unit 244 and are then conveyed to the cutting unit 245. When the conveying drive unit 243 has conveyed the tabs to a set length, the conveying stops. At this time, the positioning unit 244 moves downward to press the tabs being conveyed. After pressing, the cutting unit 245 is cut. Element 245 will cut the tabs. After the tabs are cut into segments, the cut tabs are sucked and transported to the jig 211 of the film-making turntable 210 by the transport unit 246, so that the tabs are matched with the pole pieces in the jig 211. After the tabs are transported, the positioning unit 244 rises and resets, and the transport drive unit 243 transports the tabs in the transport channel 242 again, and the cycle continues, ultimately realizing automatic transport, automatic cutting and automatic transport of the tabs, thereby improving the production efficiency of the pole pieces.

[0044] The conveying drive unit 243 in this embodiment adopts rolling conveying, and the pole ear is conveyed by rotating two rollers arranged upper and lower. The positioning unit 244 is a cylinder and pressure block structure, and the cylinder drives the pressure block to move up and down. The handling unit 246 also adopts a PPU manipulator. The structures of the above units are all existing technologies, so they will not be elaborated in detail.

[0045] In addition, in order to realize automatic cutting of the tabs, the cutting unit 245 in this embodiment includes a cutting knife 2451, a material receiving platform 2452, a limit block 2453 and a cutting cylinder 2454. The cutting knife 2451 is located above the end of the conveying channel 242, and the material receiving platform 2452 is connected to the end of the conveying channel 242 through a tension spring 2455. The limit block 2453 limits the material receiving platform 2452, and the cutting cylinder 2454 is respectively connected to the cutting knife 2451 and the limit block 2453, and drives the cutting knife 2451 and the limit block 2453 to rise and fall.

[0046] When the conveying drive unit 243 outputs the tab to the conveying channel 242 and delivers the set length, the cutting cylinder 2454 starts to operate and moves the cutting knife 2451 and the limit block 2453 downward. When the limit block 2453 moves downward, it will be separated from the material receiving platform 2452. The material receiving platform 2452 will move toward the end of the conveying channel 242 due to the tension of the tension spring 2455 until it moves to the set position. At this time, the cutting knife 2451 just moves down to cooperate with the material receiving platform 2452. The output tabs are cut off by the cutting knife 2451, and the cut tabs are adsorbed by the receiving platform 2452, and then the cutting cylinder 2454 drives the cutting knife 2451 and the limit block 2453 to rise and reset. The receiving platform 2452 is reset under the pressure of the limit block 2453, and the conveying unit 246 runs to suck the tabs on the receiving platform 2452 and convey them to the jig 211, so as to realize the automatic cutting of the tabs, ensure the consistency of the cutting length, and improve the production efficiency and quality of the pole pieces.

[0047] See also Figures 10 to 13 In order to achieve gluing of the welding points on the upper and lower surfaces of the tab, the tab gluing mechanism 260 in this embodiment includes a gluing mounting seat 261, an upper gluing group 262 and a lower gluing group 263. The upper gluing group 262 and the lower gluing group 263 are respectively arranged on the gluing mounting seat 261, and the upper gluing group 262 and the lower gluing group 263 have the same structure, both including a glue feeding tray 264, a molding turntable 265, a cutter unit 266 and a gluing unit 267. The glue feeding tray 264 is used to install the film, the molding turntable 265 is used to transport the film, the cutter unit 266 is used to cut the transported film into segments, and the gluing unit 267 is used to absorb the cut tape and stick it to the tab.

[0048] The edge of the forming turntable 265 is spaced apart with a plurality of bonding blocks 2651, and a cutting groove 2652 is provided in the middle of the bonding block 2651. An anti-sticking push block 2653 is also provided in the middle of the forming turntable 265. The width of the anti-sticking push block 2653 is smaller than the distance between two adjacent bonding blocks 2651. At the same time, the cutting unit 266 has two sets of cutting knives 2661. The distance between the two sets of cutting knives 2661 is adapted to the distance between the cutting grooves 2652 of two adjacent bonding blocks 2651. 267 includes a glue rotating cylinder 2671, a glue rotating seat 2672 and a glue adsorption head 2673. The glue rotating seat 2672 is connected to the glue rotating cylinder 2671. The glue rotating cylinder 2671 drives the glue rotating seat 2672 to rotate 180°, and glue adsorption heads 2673 are provided at both ends of the glue rotating seat 2672. The glue rotating seat 2672 of the upper glue group 262 rotates longitudinally, and the glue rotating seat 2672 of the lower glue group 263 rotates laterally.

[0049] Specifically, when applying glue, a tape roll (single-sided tape) is installed on the glue feeding disks 264 of the upper glue applying group 262 and the lower glue applying group 263, and then the starting end of the tape is adhered to the adhesive block 2651 on the edge of the forming turntable 265. The forming turntable 265 rotates, and the tape is transported around the several adhesive blocks 2651. When the adhesive blocks 2651 of the forming turntable 265 rotate to the cutter unit 266 with the tape, the two groups of cutters 2661 of the cutter unit 266 will move toward the adhesive block 2651. The two groups of cutters 2661 are respectively inserted into the cutting grooves 2652 in the middle of the two adjacent adhesive blocks 2651, thereby cutting the transported tape. After the tape is cut, the two ends of the tape will still adhere to the edges of the two adjacent adhesive blocks 2651. At this time, the forming turntable 265 will continue to advance. The glue adsorption head 2673 is then driven by the cylinder to move, and the tape is adhered to the ear and the welding point between the ear and the electrode, thereby realizing automatic gluing of the electrode. By means of automatic gluing, the production efficiency of the electrode is improved and the production quality of the electrode is ensured.

[0050] In this embodiment, in order to better improve production efficiency, glue adsorption heads 2673 are provided at both ends of the glue rotating seat 2672. The glue rotating seat 2672 is rotated 180° to make the two groups of glue adsorption heads 2673 run alternately. When the glue adsorption head 2673 at one end is located under the non-stick push block 2653 to absorb the adhesive tape, the glue adsorption head 2673 at the other end will be located at the pole ear to apply glue, and the alternation can be carried out to improve the glue application efficiency.

[0051] See also Figure 4 and Figure 15In order to realize the automatic unloading of the electrode, the unloading section 30 in this embodiment includes a sheet kneading unit 300, a receiving positioning line 310, a receiving robot 320, a collecting group 330, a transfer group 340, an unloading robot 350, a material box turnover line 360 and a discharging line 370. The head end of the sheet kneading unit 310 is connected to the conveyor line 280, and the tail end is connected to the receiving positioning line 310. The collecting group 330 is located at the receiving On one side of the positioning line 310, the material receiving robot 320 travels back and forth between the material receiving positioning line 310 and the material collection group 330. A defective material receiving box 380 is also provided at the end of the material receiving positioning line 310. The material transfer group 340 is used to transfer the electrodes collected in the material collection group 330. The unloading robot 350 transports the electrodes transferred by the material transfer group 340 to the turnover box of the material box turnover line 360, and the discharging assembly line 370 transports the turnover box.

[0052] When the gluing work is completed, the film turntable 210 will carry the electrode in the fixture 211 to the unloading and handling module 270, and the unloading and handling module 270 will transport the electrode in the fixture 211 to the conveyor line 280. The electrode is transported in sequence through the conveyor line 280, and will be inspected by the CCD detection mechanism 290 during the transportation process. The electrode after inspection will be directly transported to the kneading unit 300 of the unloading section 30, and the electrode will be shaped and flattened by the kneading unit 300. The kneading unit 300 is an existing technology and adopts a pressure roller structure. After the electrode is kneaded and shaped, it will be transported to the receiving positioning line 310, and the CCD detection mechanism 290 will detect that it is not Good products, the electrodes will be transferred from the receiving positioning line 310 to the defective receiving box 380 for collection. If the CCD detection mechanism 290 detects that it is a good product, the receiving robot 320 will absorb the electrodes on the receiving positioning line 310 and transport them to the collecting group 330. When the collecting group 330 collects the set number of electrodes, the transfer group 340 will transfer the electrodes of the collecting group 330, and the unloading robot 350 will clamp all the electrodes of the transfer group 340 and transport them to the turnover box on the material box turnover line 360. The turnover box will then be discharged and transported by the discharging assembly line 370, and finally the automatic sorting and collection of the electrodes will be realized, thereby reducing manual operations and improving the production efficiency and quality of the electrodes.
