[0033] See also Figure 6 and Figure 7 As shown, the conveying assembly includes a mounting frame 14, a conveying roller 141, a driving motor 142 and a tensioning assembly. The mounting frame 14 is fixedly connected symmetrically between the front and rear side surfaces of the workbench 1. Two conveying rollers 141 are rotatably connected on the mounting frame 14. When the conveying rollers 141 rotate, the conveying rollers 141 can drive the battery pole piece to move to the right. The front sides of the upper and lower conveying rollers 141 are connected by gear transmission. A driving motor 142 is installed on the upper part of the rear side of the mounting frame 14. The output shaft end of the driving motor 142 is fixedly connected to the rear end of the upper conveying roller 141. A tensioning assembly is provided between the mounting frame 14 and the workbench 1. When the tensioning assembly is in operation, the tensioning assembly can tighten the battery pole piece. The components include an electric slide rail 143, a movable plate 144, a sliding frame 145 and a pressure roller 147. The electric slide rail 143 is symmetrically installed on the front and back bottom of the mounting frame 14. A movable plate 144 is fixed between the moving parts of the electric slide rails 143 on the front and back sides. The movable plate 144 is at the same horizontal height as the cutting platform 6. The sliding frame 145 is vertically slidably connected to the movable plate 144. The middle part of the sliding frame 145 is rotatably fitted with a pressure roller 147. When the pressure roller 147 moves, the pressure roller 147 can tighten the battery electrode. Guide grooves 146 are symmetrically opened on the front and back sides of the workbench 1. The inner side of the guide groove 146 is slidably connected to the end of the sliding frame 145. The guide groove 146 consists of an inclined section and a straight section.

[0034] Initially, the connecting spring 132 is in a compressed state. First, the size of the battery electrode to be cut by the laser cutting machine 41 is set by programming, and the moving path of the three-axis moving machine 4 is adjusted. Then, the winding drum with the wound battery electrode is placed between the grooves of the front and rear support plates 3. Then, the head end of the battery electrode is pulled to move between the two conveying rollers 141 on the left. The driving motor 142 is started to reverse and drive the upper conveying roller 141 to reverse. The upper conveying roller 141 reverses and drives the lower conveying roller 141 to rotate forward through the gear transmission. The left conveying roller 141 rotates to pull out the battery electrode, so that the battery electrode moves to the right for conveying. The battery electrode moves to the right and passes between the pressure roller 147 and the movable plate 144. The battery electrode continues to move to the right to be conveyed on the upper and lower sides of the right. When the battery electrode is between the rollers 141, the battery electrode contacts the right conveying roller 141, the driving motor 142 is turned off, the conveying roller 141 stops rotating, and the pulled battery electrode is above the cutting platform 6. At this time, the electric slide rail 143 is started to drive the left and right movable plates 144 to move away from each other, and the movable plates 144 drive the left and right sliding frames 145 to move away from each other, and the sliding frames 145 drive the left and right pressure rollers 147 to move away from each other, and the sliding frames 145 move in the guide groove 146. The guide groove 146 first drives the sliding frame 145 to move downward, and the sliding frame 145 drives the pressure roller 147 to move downward and contact the battery electrode, and then the sliding frame 145 continues to move to the right and contacts the straight section of the guide groove 146. 45 stops and drives the pressure roller 147 to continue to move downward, the movable plate 144 and the pressure roller 147 cooperate to clamp the two sides of the battery electrode, and then the movable plates 144 and the pressure roller 147 on the left and right sides move away from each other to pull the battery electrode to both sides, which also tightens the battery electrode, and turns off the electric slide 143, and the pressure roller 147 and the movable plate 144 stop moving to prevent the uneven protrusion or depression of the battery electrode from affecting the accuracy of laser cutting, thereby ensuring the accuracy of laser cutting of the battery electrode, and then start the vacuum adsorption device on the cutting platform 6 to suck and fix the battery electrode, and then start the three-axis moving machine 4 to drive the laser cutting machine 41 to move, so that the laser cutting machine 41 moves to the initial starting cutting position of the battery electrode, and start the three-axis moving machine 4 to drive the laser cutting machine 41 moves downward to approach the battery electrode, and then starts the laser cutting machine 41 to start laser cutting the battery electrode. The cut block battery electrode remains on the cutting platform 6. As the battery electrode is continuously cut into block battery electrode, the three-axis moving machine 4 continuously moves to the right, driving the laser cutting machine 41 to move to the right. At the same time, the three-axis moving machine 4 drives the L-shaped rod 136 to move to the right. The L-shaped rod 136 moves to the right and breaks away from the contact with the arc plate 137. Due to the action of the connecting spring 132, the movable frame 131 moves to the right, driving the limit rod 133 and the fixed plate 134 to move to the right. The fixed plate 134 drives the swing plate 135 to move to the right. The swing plate 135 moves to the right synchronously with the limit rod 133. When the swing plate 135 moves to the right and contacts the contact rod 12,The contact rod 12 drives the swing plate 135 to swing upward, and the torsion spring 1341 is compressed. As the swing plate 135 continues to move to the right, the swing plate 135 slides over the contact rod 12. Due to the action of the torsion spring 1341, the swing plate 135 swings downward and resets to contact the limit rod 133 and is limited. When the laser cutting of the battery electrode on the cutting platform 6 is completed, the three-axis moving machine 4 drives the laser cutting machine 41 to move upward and reset, and then the three-axis moving machine 4 drives the laser cutting machine 41 to move to the left and reset. At the same time, the three-axis moving machine 4 drives the L-shaped rod 136 to move to the left and reset. The L-shaped rod 136 moves to the left and contacts the curved plate 137. The L-shaped rod 136 drives the curved plate 137 to move to the left, and the curved plate 137 drives the movable frame 131 to move left and reset. The movable frame 131 drives the limiting rod 133 and the fixed plate 134 to move to the left, and the fixed plate 134 drives the swinging plate 135 to move to the left. The swinging plate 135 moves to the left and contacts the contact rod 12. Due to the limitation of the limiting rod 133 on the swinging plate 135, the swinging plate 135 cannot swing to the right. The swinging plate 135 drives the contact rod 12 to move upward, and the contact rod 12 drives the tooth block 11 to move upward, and the tooth block 11 drives the gear shaft 10 to rotate forward. The gear shaft 10 rotates forward through the rotating shaft 7 to drive the cutting platform 6 to swing downward. The cutting platform 6 swings downward and drives the fixed frame 9 to swing downward. The elastic telescopic rod 8 is compressed, and the cutting platform 6 swings downward in an inclined state. The block battery electrode cut by the laser is removed from the cutting plane. The battery blocks on the guide plate 5 are collected and collected, and the battery blocks are collected and processed without manual intervention, and the automatic unloading is completed. The degree of automation is high, thereby improving the cutting efficiency. As the swing plate 135 and the fixed plate 134 continue to move to the left, the swing plate 135 is out of contact with the contact rod 12, and the fixed plate 134 moves to the left and contacts the contact rod 12. The fixed plate 134 continues to move to the left and resets and is out of contact with the contact rod 12. Due to the action of the elastic telescopic rod 8, the fixed frame 9 drives the cutting platform 6 to swing upward and reset. The cutting platform 6 drives the gear shaft 10 to reverse and reset through the rotating shaft 7. The gear shaft 10 drives the gear block 11 to move downward and reset. The gear block 11 drives the contact rod 12 to move downward and reset. At this time, the cutting platform 6 is started. The electric slide rail 143 drives the left and right movable plates 144 to move closer to each other and reset, which in turn drives the left and right sliding frames 145 to move closer to each other and reset. The guide groove 146 drives the movable frame 131 to move upward and reset. The movable frame 131 drives the pressure roller 147 to move upward and reset to disengage from the battery electrode sheet. The vacuum adsorption device on the cutting platform 6 is closed, and the battery electrode sheet stops being sucked. Then the drive motor 142 is started again, so that the conveying roller 141 rotates and continues to drive the battery electrode sheet to move to the right for conveying, so that the next part of the battery electrode sheet moves to the laser cutting area. According to the above operation, the battery electrode sheet can be laser cut again. This process is repeated to cut a roll of battery electrode sheets into block-shaped battery electrode sheets. When all the battery electrode sheets in a roll are laser cut into block-shaped battery electrode sheets,Remove the winding drum for winding the battery electrode sheet from the support plate 3, and then perform subsequent processing on the block-shaped battery electrode sheet.

[0035] See also Figure 8 and Figure 9 As shown, the battery electrode laser cutting device also includes a dust collection component installed on the moving part of the three-axis moving machine 4, the dust collection component includes a dust collection pump 15, a hose 151, an annular tube 152, a dust collection tube 1521, a dust cover 153 and an annular brush 154, and the dust cover 153 is fixed to the bottom of the laser cutting machine 41. When the laser cutting machine 41 performs laser cutting on the battery electrode, the dust cover 153 can block the smoke and debris generated by the cutting. An annular brush 154 is fixedly connected to the bottom along the circumferential direction to block smoke and dust. An annular tube 152 is fixedly connected to the top of the dust cover 153. Eight dust suction pipes 1521 are connected to the bottom of the annular tube 152 at evenly spaced intervals along the circumference. The dust suction pipes 1521 are fixedly passed through the dust cover 153. A dust suction pump 15 is installed on the moving part of the three-axis moving machine 4. The dust suction end of the dust suction pump 15 is connected to a hose 151, and the tail end of the hose 151 is connected to the right side of the annular tube 152.

[0036] When the three-axis moving machine 4 drives the laser cutting machine 41 to move downward and approach the battery pole piece, the laser cutting machine 41 moves downward and drives the dust cover 153 to move downward. The dust cover 153 moves downward and drives the annular brush 154 to move downward. The annular brush 154 moves downward and contacts the battery pole piece. When the laser cutting machine 41 laser cuts the battery pole piece, the dust cover 153 and the annular brush 154 block the dust and debris generated by the laser cutting. The dust suction pump 15 is started. The dust suction pump 15 creates a negative pressure state in the dust suction pipe 1521 through the hose 151 and the annular pipe 152. The dust suction pipe 1521 extracts and collects the dust and debris generated by the laser cutting. As the laser cutting machine 41 continues to move to laser cut the battery pole piece, the laser cutting machine 41 drives the annular brush 154 to move through the dust cover 153. The movement of the annular brush 154 can sweep away and remove the debris remaining on the battery pole piece. After the battery electrode laser cutting is completed, the dust pump 15 is turned off, and the laser cutting machine 41 moves upward, driving the dust cover 153 to move upward and reset. The dust cover 153 then drives the annular brush 154 to move upward and reset. This prevents the dust and debris generated by the laser cutting from affecting the surrounding working environment, thereby ensuring a good working environment.

[0037] See also Figure 10 As shown, the battery pole piece laser cutting device further includes a vibration motor 16 , and three vibration motors 16 are evenly spaced and installed on the bottom of the cutting platform 6 .

[0038] When the cutting platform 6 swings downward to cause the battery block sheets to fall off for unloading, the vibration motor 16 is started to vibrate the cutting platform 6, which in turn vibrates the battery block sheets. When the battery block sheets are unloaded, the vibration motor 16 is turned off. In this way, the battery block sheets can fall off the cutting platform 6 more smoothly and complete unloading.
