Detailed implementation manners

[0020] The embodiments of the present utility model will be described in detail below. Referring to Figures 1 to 3 , an embodiment of the present utility model provides a battery pole piece forming device for realizing the forming of a battery pole piece with a single-piece structure for the incoming pole piece. The battery pole piece forming device includes a frame 100 and a loading module 200, a cutter module 300, a supporting platform 400, and an unloading module 500 provided on the frame 100; the loading module 200 is used to place materials on the supporting platform 400; the cutter module 300 is used to cut the materials on the supporting platform 400 to cut the materials into battery pole pieces; the unloading module 500 is used to take away the battery pole pieces on the supporting platform 400. This device uses the loading module 200 to transfer and place the materials to be cut onto the supporting platform 400, and uses the cutter module 300 to cut the materials on the supporting platform 400, thereby obtaining battery pole pieces with the required dimensions and shapes. Then, the unloading module 500 is used to take away the cut battery pole pieces on the supporting platform 400. Therefore, this device can conveniently and quickly realize loading, cutting, and unloading, realize the automatic and rapid forming of battery pole pieces with a single-piece structure for the incoming pole piece, save manpower and material resources, and improve production efficiency.

[0021] Furthermore, referring to Figure 1 , the loading module 200 includes a first material rack 210 and a loading manipulator 220; the first material rack 210 is used to store the materials to be processed; the loading manipulator 220 is used to transfer the materials on the first material rack 210 to the supporting platform 400.

[0022] Regarding the loading method of the loading module 200, in some embodiments, the loading manipulator 220 can rotate relative to the frame 100 and can move vertically relative to the first material rack 210 and the supporting platform 400:

[0023] When loading materials, the loading manipulator 220 first rotates relative to the frame 100 to the upper side of the first material rack 210, then moves downward relative to the first material rack 210, picks up the materials by means of grasping or adsorption, etc., then moves upward and rotates to the upper side of the supporting platform 400, and finally moves downward and releases the materials relative to the supporting platform 400, so that the materials can be smoothly placed on the supporting platform 400. In addition, a tray capable of stacking multiple pieces of materials can be provided at the bottom of the first material rack 210, and a lifting module is provided at the bottom of the tray. The lifting module can lift the tray and the materials on the tray upward to cooperate with the loading manipulator 220 to pick up materials. For example, after each piece of material is taken away, the lifting module lifts the tray upward by the height of one piece of material, so that the travel of the loading manipulator 220 each time it moves downward to pick up materials remains unchanged. By setting the rotation angle and the up-and-down movement travel of the loading manipulator 220, it can be ensured that the loading manipulator 220 can accurately pick up materials from the first material rack 210 and accurately place the materials on the supporting platform 400.

[0024] In some embodiments, the loading manipulator 220 can move horizontally relative to the frame 100 and can move vertically relative to the first material rack 210 and the supporting platform 400:

[0025] When loading materials, the loading manipulator 220 first translates relative to the frame 100 to the upper side of the first material rack 210, then moves downward relative to the first material rack 210, picks up the materials by means of grasping or adsorption, etc., then moves upward and translates to the upper side of the supporting platform 400, and finally moves downward and releases the materials relative to the supporting platform 400, so that the materials can be smoothly placed on the supporting platform 400. By setting the translation and vertical movement travel of the loading manipulator 220, it can be ensured that the loading manipulator 220 can accurately pick up materials from the first material rack 210 and accurately place the materials on the supporting platform 400. Of course, the loading manipulator 220 described here can move horizontally relative to the frame 100, which can be Figure 1 as shown, a horizontal movement in one direction. At this time, the first material rack 210 and the supporting platform 400 can be arranged on the same straight line. Of course, the loading manipulator 220 can also be a horizontal movement in multiple directions. Specifically, which method can be selected and adjusted according to the actual application scenario.

[0026] For the loading method of the loading module 200, it can be selected and arranged according to aspects such as the space size of the production site, the relationship between the front and rear workstations, the production scale, and the cost. Of course, the loading methods of the loading module 200 are not limited to the above several. The loading manipulator 220 can also have other movement loading methods, which will not be elaborated here. As long as the materials are transferred from the first material rack 210 to the supporting platform 400 by means of grasping or adsorption, etc., it should belong to the loading module 200 described in this application. Herein, in combination with Figure 1Some more specific feeding methods will be described: The first material rack 210 includes a positioning frame 211 and a lifting tray 212 disposed within the positioning frame 211. The lifting tray 212 is used to stack multiple materials to be cut, and can drive the materials to move upward within the positioning frame 211 under the action of a lifting driving member. The positioning frame 211 can circumferentially limit the materials to ensure the accurate position of the materials within the first material rack 210. The supporting platform 400 and the first material rack 210 are arranged on the same straight line. Above this straight line, a horizontal guide rail is provided. A vertical driving member is slidably mounted on the horizontal guide rail. The feeding manipulator 220 adopts a suction cup structure and is installed at the output end of the vertical driving member. The vertical driving member can be a structure such as a cylinder. When the vertical driving member moves horizontally along the horizontal guide rail, it can drive the feeding manipulator 220 to move horizontally relative to the frame 100, realizing the reciprocating movement between the first material rack 210 and the supporting platform 400. And the vertical driving member can also drive the feeding manipulator 220 to move up and down to approach / away from the first material rack 210 / supporting platform 400, so as to facilitate the picking and placing of materials.

[0027] Furthermore, in some embodiments, the supporting platform 400 is a vacuum adsorption platform to ensure that when the cutting blade module 300 cuts the material, the material can be fixed on the supporting platform 400. In some other embodiments, the material can also be fixed on the supporting platform 400 through other positioning structures, such as a pressing block with a buffer member, etc.

[0028] Furthermore, the cutting blade module 300 includes a first cutting blade assembly 310, a second cutting blade assembly 320, and a third cutting blade assembly 330; the first cutting blade assembly 310 is used to cut the side edges of the material; the second cutting blade assembly 320 is used to cut the bottom edge of the material; the third cutting blade assembly 330 is used to cut the tabs on the material.

[0029] Regarding the positional relationship among the first cutting blade assembly 310, the second cutting blade assembly 320, and the third cutting blade assembly 330, in some embodiments, the first cutting blade assembly 310 and the second cutting blade assembly 320 can be the same cutting blade assembly. At this time, the loading manipulator 220 is a rotatable manipulator, or the supporting platform 400 is a rotatable platform. After the cutting blade assembly cuts one side of the material, the loading manipulator 220 or the supporting platform 400 drives the material to rotate, so that the bottom edge of the material rotates to the cutting blade assembly. After cutting the bottom edge of the material, then rotate the other side of the material to the cutting blade assembly for cutting, and finally transfer the material to the third cutting blade assembly 330 for cutting the tab. In some embodiments, there are two sets of the first cutting blade assemblies 310 arranged oppositely to correspondingly cut two opposite sides of the material. The second cutting blade assembly 320 and the third cutting blade assembly 330 are also arranged oppositely, and the two first cutting blade assemblies 310, the second cutting blade assembly 320, and the third cutting blade assembly 330 are distributed on the four sides of a rectangle and are arranged towards the center of the rectangle. The supporting platform 400 is located at the center of the rectangle. The two first cutting blade assemblies 310, the second cutting blade assembly 320, and the third cutting blade assembly 330 can be started for cutting simultaneously, so as to complete the cutting and forming of the battery electrode sheet at one time. The formed battery electrode sheet can be transferred and taken away by means of a manipulator or other structures.

[0030] Of course, the first cutting blade assembly 310, the second cutting blade assembly 320, and the third cutting blade assembly 330 can also have other setting methods, which will be described below with reference to the attached Figure 1 for example:

[0031] A guiding member 110 is provided on the frame 100. The guiding member 110 is a structure such as a horizontal slide rail or a chute. The supporting platform 400 is slidably connected to the guiding member 110. The first cutting blade assembly 310, the second cutting blade assembly 320, and the third cutting blade assembly 330 are located at the side of the guiding member 110. There are two sets of the first cutting blade assemblies 310 arranged oppositely on both sides of the guiding member 110, which are respectively used for cutting two sides of the material. The second cutting blade assembly 320 and the third cutting blade assembly 330 are arranged oppositely on both sides of the guiding member 110. After the material is cut at the two first cutting blade assemblies 310 to complete two sides, it is then transferred between the second cutting blade assembly 320 and the third cutting blade assembly 330 for cutting the bottom edge and the tab. After the material is cut at two sides, the material needs to be rotated by 90 degrees. This rotation can be realized by a manipulator or by rotating the supporting platform 400. For example Figure 1As shown, a slide table 120 is slidably connected to a guide member 110, and a supporting platform 400 is rotatably connected to the slide table 120. When cutting two sides of the material to be cut, the slide table 120 drives the supporting platform 400 to move between two first cutter assemblies 310. After the two sides are cut, the supporting platform 400 drives the material to rotate 90 degrees, and then the slide table 120 drives the supporting platform 400 to transfer to between the second cutter assembly 320 and the third cutter assembly 330, waiting to cut the bottom edge and the tab.

[0032] For the transfer of the material between the first cutter assembly 310 and the second cutter assembly 320 / the third cutter assembly 330, in some other embodiments, a supporting platform 400 can also be arranged between the two first cutter assemblies 310, and a supporting platform 400 can also be arranged between the second cutter assembly 320 and the third cutter assembly 330, and a manipulator is used to realize the transfer of the material between the supporting platforms 400. For the setting method of multiple supporting platforms 400, when the bottom edge and the tab of the current material are cut, the next material can be cut on the side at the same time, which can further improve the production efficiency. For the setting method of a single supporting platform 400, it can avoid damaging the material due to multiple picking and placing of the material, thus ensuring the performance of the battery electrode sheet.

[0033] Furthermore, the positions of the first cutter assembly 310, the second cutter assembly 320, and the third cutter assembly 330 on the frame 100 are all adjustable to realize the forming of electrode sheets with different lengths and widths. More specifically, the distance between the two first cutter assemblies 310 can be adjusted, so as to adjust the width of the electrode sheet by adjusting the sizes of the two cut sides; the distance between the second cutter assembly 320 and the third cutter assembly 330 can be adjusted, so as to adjust the length of the electrode sheet and the length of the tab by adjusting the size of the cut bottom edge and the size of the tab position; specifically, the distance adjustment can be realized by using a slide rail or by setting multiple mounting holes. Further, referring to Figure 2 and Figure 3 , the structures of the first cutter assembly 310, the second cutter assembly 320, and the third cutter assembly 330 are similar, including a mounting frame 340 and an upper cutter 350 and a lower cutter 360 arranged on the mounting frame 340. When the upper cutter 350 and the lower cutter 360 are engaged, the material can be cut. For the third cutter assembly 330, since it is necessary to cut and form the tab, a relief notch 351 is provided at the upper cutter 350 to retain the material at the corresponding position on the material to form the tab.

[0034] Furthermore, the battery electrode forming device further includes a size detection module 600 disposed on the frame 100. The size detection module 600 is arranged between the cutting tool module 300 and the blanking module 500, and a CCD detection system is used to detect the size of the battery electrode. The blanking module 500 includes a second material rack 510, a third material rack 520, and a blanking manipulator 530. The second material rack 510 is used to store the battery electrodes that pass the size detection. The third material rack 520 is used to store the battery electrodes that fail the size detection. The blanking manipulator 530 is used to transfer the battery electrodes on the supporting platform 400 to the second material rack 510 or the third material rack 520. Another supporting platform 400 can be provided at the size detection module 600, and a manipulator is used to place the formed battery electrodes on this supporting platform 400. Or only one supporting platform 400 can be provided, and the supporting platform 400 can slide along the guide member 110 to the size detection module 600. The products that pass the detection of the size detection module 600 are transferred to the second material rack 510 by the blanking manipulator 530, while the unqualified products are transferred to the third material rack 520 by the blanking manipulator 530. For the structure and movement process of the blanking manipulator 530, and the structures of the second material rack 510 and the third material rack 520, reference can be made to the loading manipulator 220 and the first material rack 210, which will not be elaborated here.
