[0043] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0044] like Figure 1 As shown, this embodiment provides an automatic cutting and bonding device for flexible battery separator paper, which includes a substrate feeding mechanism 1, a worktable 2, a substrate unloading mechanism 3, a separator paper gripping and bonding mechanism 4, and a separator paper cutting mechanism 5.

[0045] The substrate feeding mechanism 1 conveys the flexible battery substrate 6 to the worktable 2. The flexible battery substrate 6 is laid on the worktable 2, and the worktable 2 can hold and fix the flexible battery substrate 6 in place when the separator paper 7 is applied. The separator paper cutting mechanism 5 cuts the entire sheet of separator paper into the required size. During application, the separator paper gripping and applying mechanism 4 picks up the cut separator paper 7 from the separator paper cutting mechanism 5 and then applies the separator paper 7 to the flexible battery substrate 6. Figure 12 As shown, after the bonding is completed, it enters the next station from the substrate unloading mechanism 3.

[0046] like Figure 4 As shown, the workbench 2 in this embodiment includes a suction work plate 21, a platform support frame 22, and a suction base plate 23. The platform support frame 22 is located at the bottom of the suction work plate 21. The suction work plate 21 has several suction holes 24. The suction base plate 23 is connected to the bottom of the suction work plate 21 and is located below the suction holes 24. The bottom of the suction base plate 23 has air holes. The flexible battery substrate 6 is laid on the suction work plate 21. The air holes at the bottom of the suction base plate 23 are connected to an external vacuum pump. During bonding, the vacuum pump draws air, which is then adsorbed and fixed to the flexible battery substrate 6 through the suction holes 24 on the suction work plate 21. After bonding is completed, the vacuum pump stops drawing air, and the substrate feeding mechanism 1 is started, which moves the flexible battery substrate 6 toward the substrate unloading mechanism 3. Then, the bonding operation of the separator paper 7 can continue for the subsequent flexible battery substrate 6.

[0047] like Figure 4 , 12 As shown, in this embodiment, a deviation detection device is also added to the suction working plate 21, which uses a color sensor 8. The flexible battery substrate 6 has a white background, and black marks 61 are drawn at equal intervals on the edge of the flexible battery substrate 6. During the movement of the flexible battery substrate 6, the color sensor 8 can continuously identify the black marks 61 on the edge of the flexible battery substrate 6 within the same time interval. If the position of the flexible battery substrate 6 deviates during the movement, the color sensor 8 will not be able to identify the black marks 61, triggering a deviation alarm, and then the position of the flexible battery substrate 6 will be manually adjusted.

[0048] like Figure 2 As shown, the substrate feeding mechanism 1 in this embodiment includes a first pressure roller assembly 11, a dragging driven roller 12, an arc-shaped base plate 13, a dragging active roller 14, a dragging motor 15, and a second pressure roller assembly 16.

[0049] The arc-shaped base plate 13 is fixed on the platform support frame 22, and there is a gap between the upper end of the arc-shaped base plate 13 and one end of the suction working plate 21.

[0050] The material-carrying driven roller 12 is disposed on the inner side of the lower end of the arc base plate 13 and is rotatably connected to the platform support frame 22. The first pressure roller assembly 11 is fixed to one end of the platform support frame 22. The first pressure roller assembly 11 is disposed opposite to the material-carrying driven roller 12 and is located on the outer side of the lower end of the arc base plate 13. The first pressure roller assembly 11 is used to press the flexible battery substrate 6 onto the material-carrying driven roller 12.

[0051] The material-dragging active roller 14 is located below the gap between the upper end of the arc base plate 13 and one end of the suction working plate 21. The material-dragging active roller 14 is rotatably connected to the platform support frame 22. The material-dragging motor 15 is fixed on the side wall of the platform support frame 22. The motor shaft of the material-dragging motor 15 is connected to the material-dragging active roller 14.

[0052] The second pressure roller assembly 16 is fixed on the platform support frame 22. The second pressure roller assembly 16 is arranged opposite to the material dragging active roller 14. The second pressure roller assembly 16 is used to press the flexible battery substrate 6 onto the material dragging active roller 14.

[0053] The flexible battery substrate 6 enters the arc-shaped base plate 13 between the first pressure roller assembly 11 and the dragging driven roller 12, then passes through the gap between the arc-shaped base plate 13 and the suction working plate 21, and finally is laid on the suction working plate 21. During feeding, the dragging motor 15 is started to drive the dragging drive roller 14 to rotate, and the second pressure roller assembly 16 presses the flexible battery substrate 6 onto the dragging drive roller 14, which in turn drives the flexible battery substrate 6 to move.

[0054] like Figure 4As shown, the diaphragm paper gripping and bonding mechanism 4 of this embodiment includes an X-axis linear module 41, a Z-axis linear module 42, a first fixing plate 43, a second fixing plate 44, an air distribution 45, a mounting frame 46, and bonding heads 47. The X-axis linear module 41 is disposed above the suction working plate 21. The Z-axis linear module 42 is connected to the X-axis linear module 41. The first fixing plate 43 is connected to the Z-axis linear module 42. The air distribution 45 is fixed on the second fixing plate 44. The second fixing plate 44 is fixed on the first fixing plate 43. The mounting frame 46 is connected to the first fixing plate 43. Several bonding heads 47 are fixed on the mounting frame 46. The air distribution 45 is connected to the bonding heads 47 through pipelines. During bonding, the X-axis linear module 41 drives the Z-axis linear module 42 and the bonding head 47 to move upwards towards the separator paper cutting mechanism 5. Then, the Z-axis linear module 42 drives the bonding head 47 downwards to the cut separator paper 7. The external vacuum pump starts to suck in air, and the air distributor 45 is connected to the external vacuum pump. Through the air distributor 45, all bonding heads 47 start sucking in air, holding the separator paper 7 in place. Then, the Z-axis linear module 42 and the X-axis linear module 41 drive the separator paper 7 back above the flexible battery substrate 6. Next, the Z-axis linear module 42 drives the bonding head 47 and the separator paper 7 downwards, bonding the separator paper 7 onto the flexible battery substrate 6.

[0055] like Figure 4 As shown, the substrate feeding mechanism 3 in this embodiment includes feeding side plates 31, feeding baffles 32, guide rods 33, and rollers 34. Two feeding side plates 31 are fixed to the other end of the platform support frame 22. Both ends of the rollers 34 are connected to the two feeding side plates 31. Multiple rollers 34 are provided, and each roller passes through the two feeding baffles 32. Linear bearings are provided on the feeding baffles 32, and these bearings are mounted on the guide rods 33. Both ends of the guide rods 33 are connected to the two feeding side plates 31. The flexible battery substrate 6, with the separator paper 7 attached, is fed from the rollers 34 and enters the next station. The two feeding baffles 32 can limit the movement of the flexible battery substrate 6 during feeding, and the distance between the two feeding baffles 32 is adjustable to accommodate flexible battery substrates 6 of different widths. A pressure plate 301 is also installed between the two feeding side plates 31. The pressure plate 301 is located above the roller 34, which can prevent the flexible battery substrate 6 from detaching from the roller 34 during the feeding process and ensure smooth feeding.

[0056] like Figure 3As shown, the first pressure roller assembly 11 and the second pressure roller assembly 16 in this embodiment adopt the same structure. The pressure roller assembly includes a pressure roller 91, a pressure roller shaft 92, a shaft head slider 93, a support 94, a screw 95, a spring 96, and a nut 97. Two pressure rollers 91 are rotatably connected to the pressure roller shaft 92, pressing the flexible battery substrate 6. The shaft head slider 93 is fixed at both ends of the pressure roller shaft 92 and can slide within the support 94. The screw 95 is connected to the spring 96, and the spring 96 is connected to the shaft head slider 93. The nut 96 is screwed to the screw 95, and the screw 97 is fixed to the support 94. The nut 97 abuts against the support 94. Tightening the nut 97 adjusts the position of the nut 97 on the screw 95, thereby adjusting the position of the shaft head slider 93, and realizing the position adjustment of the pressure roller shaft 92 and the pressure roller 91.

[0057] like Figure 6 As shown, the diaphragm paper cutting mechanism 5 of this embodiment includes a diaphragm paper active conveying component 51, a diaphragm paper passive conveying component 52, a laser cutter 53, and a laser cutting platform 54.

The cut diaphragm paper 7 is wound on the diaphragm paper active conveying assembly 51, and the uncut diaphragm paper 7 is wound on the diaphragm paper passive conveying assembly 52. ​​The diaphragm paper active conveying assembly 51 provides power for conveying the diaphragm paper 7.

[0059] The laser cutting platform 54 is positioned between the diaphragm paper active conveying assembly 51 and the diaphragm paper passive conveying assembly 52, and is used to carry the diaphragm paper 7.

[0060] The laser cutting machine 53 is located above the laser cutting platform 54 and is used to cut the diaphragm paper 7 on the laser cutting platform 54.

[0061] like Figure 7 As shown, the diaphragm paper active conveying assembly 51 of this embodiment includes a diaphragm paper conveying motor 511, a diaphragm paper drive shaft 512, a first bracket 513, a diaphragm paper active drag roller 514, a pressure bar 515, a guide arc plate 516, a diaphragm paper pressure roller assembly 517, and a first working plate 518.

[0062] The first working plate 518 is fixed on the first bracket 513, and the guide arc plate 516 is fixed on the first bracket 513 with its upper end connected to the first working plate 518.

[0063] The diaphragm paper active drag roller 514 is located on the inner side of the lower end of the guide arc plate 516 and is rotatably connected to the first bracket 513. The two ends of the pressure rod 515 are connected to the first bracket 513 and the pressure rod 515 is located on the outer side of the lower end of the guide arc plate 516.

[0064] The structure of the diaphragm paper pressure roller assembly 517 is as follows: Figure 8 As shown, the diaphragm paper pressure roller assembly 517 includes a pressure roller motor 5171, a diaphragm paper active pressure roller 5172, and a diaphragm paper driven pressure roller 5173. The diaphragm paper active pressure roller 5172 is connected to the motor shaft of the pressure roller motor 5171. A gap is left between the first working plate 518 and the guide arc plate 516. The diaphragm paper active pressure roller 5172 is located above the gap, and the diaphragm paper driven pressure roller 5173 is located below the gap. The diaphragm paper 7 is pressed between the diaphragm paper active pressure roller 5172 and the diaphragm paper driven pressure roller 5173.

[0065] The diaphragm paper conveying motor 511 is fixed on the frame of the equipment. The motor shaft of the diaphragm paper conveying motor 511 is connected to the diaphragm paper drive shaft 512, which is located below the diaphragm paper drive roller 514. When conveying the diaphragm paper 7, the diaphragm paper conveying motor 511 drives the diaphragm paper drive shaft 512 to rotate, winding up the cut diaphragm paper 7. At the same time, the pressure roller motor 5171 drives the diaphragm paper drive pressure roller 5172 to rotate, providing auxiliary power for the conveying of the diaphragm paper 7. Then, it moves the uncut diaphragm paper 7 on the driven conveying assembly 52 to the laser cutting platform 54.

[0066] like Figure 7 As shown, the diaphragm paper driven conveying assembly 52 of this embodiment includes a diaphragm paper driven shaft 521, a second bracket 522, a second working plate 523, two diaphragm paper feeding side plates 524, two diaphragm paper feeding baffles 525, two diaphragm paper feeding guide rods 526, and two diaphragm paper support rollers 527. The second working plate 523 is fixed to the second bracket 522, and the two diaphragm paper feeding side plates 524 are fixed to one end of the second bracket 522.

The two ends of the diaphragm paper feeding guide rods 526 are connected to the two diaphragm paper feeding side plates 524. The diaphragm paper driven shaft 521 is located below the diaphragm paper support rollers 527. Uncut diaphragm paper 7 is wound around the diaphragm paper driven shaft 521. The diaphragm paper 7 passes over the diaphragm paper support rollers 527 and is limited by the diaphragm paper feeding baffles 525 to prevent the diaphragm paper 7 from tilting during movement. Then the diaphragm paper 7 enters the second working plate 523 and the laser cutting platform 54 in sequence.

The wire mesh 541 passes sequentially through the wire mesh drive shaft 542, the first guide roller 547, the wire mesh worktable 545, the second guide roller 548, and the wire mesh driven shaft 546. When laser cutting the diaphragm paper 7, the diaphragm paper 7 is laid flat on the wire mesh 541, and the wire mesh worktable 545 simultaneously holds the diaphragm paper 7 in place. Then, the laser cutting machine 53 can cut the diaphragm paper 7. After prolonged laser cutting, the wire mesh 541 will turn black and develop stains due to laser burning, requiring replacement with a new wire mesh 541. Simply start the wire mesh conveyor motor 543 to drive the wire mesh drive shaft 542 to rotate, winding the wire mesh 541 to be replaced onto the wire mesh drive shaft 542. At the same time, the new wire mesh 541 moves from the wire mesh driven shaft 546 to the wire mesh worktable 545, thus completing the automatic replacement of the wire mesh 541. Alternatively, instead of using wire mesh 541, laser cutting can be performed directly using wire mesh worktable 545. Wire mesh worktable 545 is placed on the third support 544 in a pull-out manner. If wire mesh worktable 545 needs to be replaced after long-term use, simply pull it out and replace it with a new wire mesh worktable 545.

[0068] like Figure 11 As shown, the wire mesh workbench 545 in this embodiment includes an upper plate 5451, a frame 5452, and a lower plate 5453.

The upper plate 5451 has several diaphragm paper suction holes 5454, and the bottom of the lower plate 5453 has an air extraction hole. The frame 5452 has a handle 5455. When cutting the diaphragm paper, the air extraction hole at the bottom of the lower plate 5453 is connected to an external vacuum pump. Starting the vacuum pump draws air, which then adheres to the diaphragm paper through the suction holes 5454 on the upper plate 5451. After cutting the diaphragm paper 7, the vacuum pump is turned off, and the diaphragm paper 7 can be moved.
