[0040] Figures 1 to 11 An embodiment of the electrode cutting machine of the present application is schematically shown.

[0041] like Figures 1 to 11As shown, the present application discloses an electrode cutting machine, including: a frame 1, and a feeding assembly 2, a material dividing assembly 3, a material pushing assembly 4, a material cutting assembly 5 and an output assembly 6 installed on the frame 1.

The material dividing assembly 3 is arranged above the feeding assembly 2, including a transfer suction cup 31 that moves back and forth. The material pushing assembly 4 is arranged on the side of the feeding assembly 2, including a material pushing rod 41 extending to the rear of the feeding assembly 2. The material cutting assembly 5 is arranged at the rear of the feeding assembly 2, including a support platform 51 and a cutting knife mechanism 52, and the support platform 51 is provided with a plurality of groups of first guide grooves 511 and a plurality of groups of second guide grooves 512 arranged alternately, and a sliding rod 513 and an adsorbent 514 are arranged in the first guide groove 511, and the second guide groove 512 partially accommodates the material pushing rod 41 to cooperate and guide the sliding of the material pushing rod 41. The output assembly 6 is arranged behind the cutting assembly 5 and includes a cutting piece conveyor belt 61 .

[0042] The electrode cutting machine of the present application is designed by the above structure, and the material distribution component and the material pushing component are arranged above and on the side of the feeding component respectively, so that the lifting and feeding, adsorption and material distribution, and front and rear pushing are organically combined, making the structure of the electrode cutting machine more compact and reasonable, occupying less space, and saving equipment space. In addition, the present application can also achieve stable and accurate stable cutting. Among them, the support platform 51 of the cutting component 5 has a first guide groove 511 and a second guide groove 512. The first guide groove 511 is provided with a slide bar 513 and an adsorbent 514, which can reduce the resistance of the electrode sheet during the pushing process, stabilize the direction of the electrode sheet, and prevent the electrode sheet from drifting. The second guide groove 512 cooperates with the pushing rod 41 to improve the parallelism of the electrode sheet movement. Thus, the present application can effectively and stably push the electrode sheet to move step by step, so as to accurately realize the pushing and cutting of the electrode sheet, improve the cutting accuracy of the electrode sheet, and ensure the product quality of the photovoltaic energy storage device finally manufactured.

[0043] In some embodiments of the present application, reference Figure 4 and Figure 5As shown, the storage bin 21 is surrounded by a bin bottom plate 211, front and rear guard plates 212, and left and right guard plates 213, thereby forming a storage space with an open top. A front and rear adjustment shaft 214 is provided between the front and rear guard plates 212, and the front and rear adjustment shaft 214 is connected to the front and rear guard plates 212 by opposite threads, so that when the front and rear adjustment shaft 214 is rotated, the front and rear guard plates 212 will be opened or retracted at the same time under the action of opposite threads; a left and right adjustment shaft 215 is provided between the left and right guard plates 213, and the left and right adjustment shaft 215 is connected to the left and right guard plates 213 by opposite threads, so that when the left and right adjustment shaft 215 is rotated, the left and right guard plates 213 will be opened or retracted at the same time under the action of opposite threads. Therefore, the feeding assembly 2 of the present application can adapt to the storage of electrode sheets of different shapes and specifications. In addition, a front and rear axle support block 216 and a left and right axle support block 217 are centrally arranged in the storage bin 21. The front and rear axle support block 216 is rotatably mounted with the front and rear adjustment shaft 214, and the left and right axle support block 217 is rotatably mounted with the left and right adjustment shaft 215. Thus, the present application can always maintain the centering of the front and rear guard plates 212 and the left and right guard plates 213 by rotatably mounting the front and rear adjustment shaft 214 and the left and right adjustment shaft 215 in the storage bin 21, so that the storage center position of the electrode sheet is not changed during the adjustment and use process, thereby improving the positioning accuracy of the electrode sheet raw material, always ensuring the centering, ensuring the success rate of the material distribution component 3 in adsorbing and transferring the electrode sheet, and effectively ensuring the efficiency and accuracy of the sheet cutting process.

[0044] In some embodiments of the present application, continue to refer to Figure 4 and Figure 5As shown, the liftable material platform 22 includes: a support plate 221, a lifting rod 222, a lifting motor 223, a lifting pulley 224, a lifting belt 225, a lifting connection seat 226 and a linear lifting guide rail 227. Among them, a plurality of lifting rods 222 are provided, which are vertically penetrated on the silo bottom plate 211 through a linear bearing, and the upper end of the lifting rod 222 is connected to the support plate 221, and the lower end is connected to the lifting connection seat 226. The lifting motor 223, the lifting pulley 224, the lifting belt 225 and the linear lifting guide rail 227 constitute a lifting power system, which is arranged below the silo bottom plate 211, that is, installed through the side support plate located below the silo bottom plate 211. The lifting pulley 224 is vertically sleeved on the lifting motor 223 and the lifting pulley 224, and the lifting connection seat 226 is slidably installed on the linear lifting guide rail 227 and connected to the lifting belt 225, so that under the linear vertical reciprocating motion of the lifting belt 225, the lifting rod 222 and the support plate 221 are driven to move vertically, so as to realize the step-by-step ascending feeding of the electrode sheet. In addition, in the embodiment of the present application, the support plate 221 of the present application is made into a hollow structure by adding a support rod 2211, that is, the area of ​​the support plate 221 is set to be smaller than the cross-sectional size of the storage bin 21, and the support rod 2211 is added to extend to expand the supporting area, so that the weight of the support plate 221 can be controlled, and the shaft support block and other structures under the support plate 221 can be installed and observed and repaired. Among them, the support plate 221 is provided with rod grooves distributed along different directions to adapt to different shapes or different cutting directions of the electrode sheet, and extend in different directions, thereby improving the adaptability of the feeding assembly 2.

[0045] In some embodiments of the present application, Figure 4 and Figure 5 As shown, a sensor rack 23 is further provided below the silo bottom plate 211, and a lifting sensor 231 is provided on the sensor rack 23, and the lifting sensor 231 is electrically connected to the lifting motor 223. After each transfer of the material distribution component 3, the lifting motor 223 steps up by one electrode sheet height, thereby ensuring that the material distribution component 3 can adsorb the electrode sheet at the same fixed height each time, thereby ensuring the success rate and efficiency of the adsorption and distribution.

[0046] In some embodiments of the present application, reference Figure 6As shown, the transfer suction cup 31 includes: a suction cup support plate 311 and a plurality of vacuum suction cups 312, and the plurality of vacuum suction cups 312 are evenly distributed on the suction cup support plate 311 to achieve multi-point simultaneous adsorption, thereby ensuring the reliability and success rate of adsorption. In addition, the material distribution component 3 also includes: a transfer cylinder 32, a transfer linear guide rail 33, a transfer support frame 34 and a lifting cylinder 35. The transfer cylinder 32 and the transfer linear guide rail 33 are arranged in parallel above the liftable material platform 22, and the transfer support frame 34 is installed on the transfer linear guide rail 33 and connected to the piston rod of the transfer cylinder 32, so that it can slide back and forth along the transfer linear guide rail 33 under the drive of the cylinder piston rod, so that the transfer suction cup 31 completes the adsorption and transfer of the electrode sheet in the front and rear directions. The lifting cylinder 35 is installed on the transfer support frame 34 in the vertical direction, and the suction cup support plate 311 is installed on the piston rod of the lifting cylinder 35 to cooperate with the vacuum suction cup 312 to achieve the lifting and adsorption of the electrode sheet.

[0047] In some embodiments of the present application, reference Figure 8 and Fig. 9 As shown, the slide bar 513 is a cylindrical rod with a smooth surface, and the adsorbent 514 is a magnet. Specifically, the slide bar 513 is made of a different material and surface roughness from the support platform 51. The slide bar 513 is made of a harder material and its surface is polished. The smooth cylindrical side surface can reduce the contact area between the slide bar 513 and the electrode sheet, thereby protecting the surface of the electrode sheet and reducing the sliding resistance of the electrode sheet, thereby overcoming the problems of large friction and uneven distribution of friction in traditional material pushing. The adsorbent 514 is a bar magnet, which is arranged parallel to the slide bar 513. It can adsorb the electrode sheet to prevent the electrode sheet from drifting freely on the slide bar 513, thereby stabilizing the position and direction of the electrode sheet. Therefore, the present application effectively solves the problem of large friction and uneven distribution of the original electrode sheet pushing friction, which easily leads to the deflection of the electrode sheet, by using the structure of the slide bar 513 and the adsorbent 514, and will not cause the electrode sheet to drift, thereby effectively improving the positioning and cutting accuracy of the electrode sheet. Figure 8 and Fig. 9 As shown, the slide rod 513 is arranged in each group of the first guide grooves 511 to ensure that each part of the electrode sheet is suspended through uniform support at multiple points. The adsorption member 514 is arranged in at least part of the first guide grooves 511, and can be specifically arranged according to the material, weight and size of the electrode sheet to perform adsorption and stabilization in the appropriate area of ​​the electrode sheet.

[0048] On this basis, the present application also alternately arranges the first guide groove 511 for constraining the electrode sheet and the second guide groove 512 for guiding the push rod 41, so as to ensure that the force on each part of the electrode sheet is balanced and will not deflect, so as to make the step-by-step cutting positioning of the electrode sheet more accurate. Figure 7The main body of the push rod 41 is in the shape of a crossbar parallel to the cutter mechanism 52, and a plurality of sliding protrusions 411 are arranged below the push rod 41, and each sliding protrusion 411 can extend into each second guide groove 512 and slide along the second guide groove 512. On the one hand, the sliding protrusion 411 can cooperate with the second guide groove 512 to realize the linear motion guidance of the push rod 41, and on the other hand, it can also penetrate to a height lower than the electrode sheet, so as to stably contact the electrode sheet and avoid the problem of material stripping due to improper position of the push rod when pushing the material.

[0049] In some embodiments of the present application, Figure 7 As shown, the pusher assembly 4 also includes: a pusher motor 42, a pusher pulley 43, a pusher belt 44, a pusher linear guide 45 and a pusher connection seat 46. The pusher belt 44 is sleeved on the pusher motor 42 and the pusher belt 44 along the front-to-back direction, and is arranged parallel to the pusher linear guide 45. The pusher connection seat 46 is slidably mounted on the pusher linear guide 45 and connected to the pusher belt 44. The pusher rod 41 is mounted on the pusher connection seat 46, so that under the drive of the pusher belt 44, the pusher rod 41 reciprocates back and forth to realize electrode sheet pushing.

[0050] In some embodiments of the present application, reference Figure 8 and Fig. 9 As shown, the cutting mechanism 52 includes: an upper cutting knife 521, a lower cutting knife 522, a spring 523 and a pressure strip 524. The lower cutting knife 522 is staggered with the upper cutting knife 521 and aligned with the pressure strip 524. When cutting, the pressure strip 524 presses the electrode sheet on the lower cutting knife 522 in advance to fix it, and then the upper cutting knife 521 is pressed down against the lower cutting knife 522 to achieve accurate cutting of the electrode sheet at the contact surface between the two. Figure 8 and Fig. 9 As shown, specifically in the embodiment of the present application, the cutting assembly 5 further includes: a cutting bottom plate 54, a cutting guide rod 55, a cutting top plate 56, a lifting plate 57 and a cutting cylinder 58. The cutting bottom plate 54 and the cutting top plate 56 are fixedly connected by a column 53. The lifting plate 57 is installed between the cutting top plate 56 and the cutting bottom plate 54 through the cutting guide rod 55. The support platform 51 and the lower cutter 522 are installed on the cutting bottom plate 54. The cutting cylinder 58 is installed on the cutting top plate 56, and the piston rod of the cutting cylinder 58 is arranged downward and connected to the lifting plate 57. The upper cutter 521 and the spring 523 are installed on the lifting plate 57, and move up and down with the lifting plate 57. The pressure strip 524 is connected to the lower end of the spring 523. When the spring 523 is in the natural state, the position of the pressure strip 524 is lower than the upper cutter 521, so that when the lifting plate 57 descends, the pressure strip 524 first contacts the electrode sheet, and pre-presses and fixes the electrode sheet on the lower cutter 522. Then, as the lifting plate 57 continues to descend, the spring 523 is compressed, making the pressing effect of the pressure strip 524 more reliable, until the upper cutter 521 contacts the electrode sheet and rises and resets again after the electrode sheet is cut.

[0051] In some embodiments of the present application, continue to refer to Figure 8 and Fig. 9 As shown, on the support platform 51, the front end of the second guide groove 512 is open, and the rear end is closed by the lower cutter 522.
