[0002] In the battery production process, a coated electrode is formed by coating the upper and lower surfaces of the foil with a wet slurry, and then the wet coated electrode is dried by hot air in an oven.

[0003] In the related art, a Chinese patent with authorization announcement number CN217450836U provides a lithium battery pole piece drying treatment device, which includes a drying box, an inlet is set at one end of the drying box, an outlet is set at the other end of the drying box, a number of conveying rollers are rotatably set in the drying box, a number of drying tubes are set in the drying box, a number of air outlets are set on the drying tubes, and an air supply mechanism is installed on the drying box, and the air supply mechanism is used to input hot gas to the drying tube. The pole piece is input into the drying box from the inlet, and the pole piece in the drying box is output from the outlet under the action of the conveying roller. During the movement of the pole piece in the drying box, the air supply component inputs hot gas into the drying tube, and the hot gas in the drying tube flows to the pole piece through the air outlet, and then the hot gas dries the pole piece.

[0004] In the process of implementing the present application, the inventors found that there are at least the following problems in this technology: since the slurry at the edge of the pole piece is less than that in the middle of the pole piece, the edge of the pole piece will dry before the middle of the pole piece. When the middle of the pole piece is dry, the edge of the pole piece is prone to cracking. Utility Model Content

[0005] In order to evenly dry the electrode and reduce the occurrence of cracking of the electrode, the present application provides a coating oven nozzle device.

[0006] The coating oven nozzle device provided in this application adopts the following technical solution:

[0008] By adopting the above technical scheme, since the aperture of the first air hole is larger than the aperture of the second air hole, and the aperture of the second air hole is larger than the aperture of the third air hole, the air volume blown out of the first air outlet is larger than the air volume blown out of the second air outlet, so the air volume blown out of the second air outlet is larger than the air volume blown out of the third air outlet, so the first carrier, the second carrier and the third carrier are arranged according to the distribution of the slurry on the electrode, the middle area of ​​the coated electrode corresponds to the first air outlet, the transition area from the middle area to the edge area of ​​the coated electrode corresponds to the second air outlet, and the edge area of ​​the coated electrode corresponds to the third air outlet. When the wet coated electrode is dried with hot air in an oven, the hot air volume blown to the middle area of ​​the coated electrode is large, the hot air volume blown to the transition area of ​​the coated electrode is moderate, and the hot air volume blown to the convenient area of ​​the coated electrode is small, so that the wet coated electrode is evenly dried and cracking at the edge of the coated electrode is reduced.

[0009] Preferably, a group of long air holes are provided on the first carrier plate, and the first air holes are all located between the long air holes.

[0010] By adopting the above technical solution, the long air holes increase the air output of the first carrier plate, which facilitates the rapid drying of the middle area of ​​the coated electrode.

[0013] Preferably, a sealing layer is fixedly provided on the outer wall of the installation frame.

[0014] By adopting the above technical solution, when the installation frame is fixed at the air outlet of the oven, the sealant layer abuts between the installation frame and the air outlet of the oven, so that hot air is not easy to leak out from the gap between the installation frame and the oven.

[0015] Preferably, a left plug board is fixedly arranged on one side of the installation frame, and the left card holder has a left slot facing the side of the installation frame, and the left slot is for the left plug board to be inserted; a right plug board is fixedly arranged on the other side of the installation frame, and the right card holder has a right slot facing the side of the installation frame, and the right slot is for the right plug board to be inserted.

[0016] By adopting the above technical solution, one side of the installation frame is plugged together with the left socket through the left plug-in plate, and the other side of the installation frame is plugged together with the right socket through the right plug-in plate, so that the left plug-in plate and the right plug-in plate can be removed from the installation frame according to the situation. When the installation frames are spliced ​​into one and fixed in the oven, the left socket and the right socket are abutted between adjacent installation frames, so that the left socket and the right socket are not easy to fall off the installation frame.

[0017] Preferably, the inner wall of the left slot, the inner wall of the right slot, the outer wall of the left inserting plate and the outer wall of the right inserting plate are all fixedly provided with a friction layer.

[0018] By adopting the above technical solution, the friction layer is made of rubber material, and the friction layer increases the friction between the left slot and the left plug block, so that the left plug block needs a certain external force to be moved out of the left slot. The friction layer increases the friction between the right slot and the right plug block, so that the right plug block needs a certain external force to be moved out of the right slot.

[0019] Preferably, a left card slot is provided on the end wall of the left card seat, a card block is slidably arranged in the left card slot, a right card slot is provided on the end wall of the right card seat, a card rod is slidably arranged in the right card slot, the card rod is connected to the card block, a card hole is provided on the card rod, and a card bolt is arranged in the card hole.

When the clamping block is moved into the left clamping slot, the left clamping seat is connected with the right clamping seat. When multiple installation frames are integrated and fixed in the oven, the clamping rod is fixed in the oven by the clamping bolt, so that the clamping rod is not easy to shake, and the clamping block is not easy to slide out of the left clamping slot.

[0022] By adopting the above technical solution, the clamping rod is pressed, and the clamping rod moves along the right clamping slot. The movement of the clamping rod drives the connecting block to move in the direction of the extrusion support spring, so that the clamping block can enter and exit the left clamping seat along the connecting slot. When the clamping block is inserted into the connecting slot of the left clamping seat, the clamping rod is released, and the support spring pushes the connecting block to move, so that the connecting block drives the clamping block to be inserted into the left clamping slot, and then the clamping block is clamped in the left clamping slot.

Figure 1, including a plurality of first carrier plates 1, a plurality of second carrier plates 2 and a plurality of third carrier plates 3, wherein adjacent first carrier plates 1 are detachably connected to the second carrier plates 2, adjacent first carrier plates 1 are detachably connected to the third carrier plates 3, and adjacent second carrier plates 2 are detachably connected to the third carrier plates 3. The first carrier plate 1 is provided with a plurality of first air holes 11 and a group of long air holes 12, the long air holes 12 increase the air volume of the first carrier plate 1, and the first air holes 11 are all located between the long air holes 12. The second carrier plate 2 is provided with a plurality of second air holes 21, and the third carrier plate 3 is provided with a plurality of third air holes 31. The aperture of the first air hole 11 is larger than the aperture of the second air hole 21, and the aperture of the second air hole 21 is larger than the aperture of the third air hole 31. Since the aperture of the first air hole 11 is larger than the aperture of the second air hole 21, and the aperture of the second air hole 21 is larger than the aperture of the third air hole 31, the air volume blown out of the first air outlet is larger than the air volume blown out of the second air outlet, so the air volume blown out of the second air outlet is larger than the air volume blown out of the third air outlet. Therefore, the first carrier 1, the second carrier 2 and the third carrier 3 are arranged according to the distribution of the slurry on the electrode, the middle area of ​​the coated electrode corresponds to the first air outlet, the transition area from the middle area to the edge area of ​​the coated electrode corresponds to the second air outlet, and the edge area of ​​the coated electrode corresponds to the third air outlet. When the wet coated electrode is dried by hot air in an oven, the hot air volume blown to the middle area of ​​the coated electrode is large, the hot air volume blown to the transition area of ​​the coated electrode is moderate, and the hot air volume blown to the convenient area of ​​the coated electrode is small, so that the wet coated electrode is evenly dried and the cracking of the edge of the coated electrode is reduced.

[0034] In order to fix the first carrier plate 1, the second carrier plate 2 and the third carrier plate 3 in the oven, refer to Figure 1 and Figure 2 The edges of the first carrier plate 1, the second carrier plate 2 and the third carrier plate 3 are all integrally formed with a mounting frame 4, and the outer wall of the mounting frame 4 is wrapped with a sealing layer 43 of rubber material, which is detachably connected to the mounting frame 4. A plurality of mounting holes 41 are provided on the mounting frame 4, and mounting bolts 42 are arranged in the mounting holes 41. The mounting frame 4 is fixed to the air outlet of the oven by the mounting bolts 42, so that the first carrier plate 1, the second carrier plate 2 and the third carrier plate 3 are installed in the oven. The sealing layer 43 abuts between the mounting frame 4 and the air outlet of the oven, so that hot air is not easy to leak out from the gap between the mounting frame 4 and the oven.

[0035] In order to make the first carrier plate 1, the second carrier plate 2 and the third carrier plate 3 be spliced ​​into one body, refer to Figures 1 to 4, a left card holder 5 is installed on one side of the installation frame 4, and a right card holder 6 is installed on the other side of the installation frame 4. A group of connecting grooves 8 are symmetrically provided on the side of the left card holder 5 away from the installation frame 4 and the side of the right card holder 6 away from the installation frame 4, and a connecting block 81 slides in the relative connecting grooves 8. A left card slot 82 is provided on the end wall of the left card holder 5, and the left card slot 82 is connected to the connecting groove 8. A card block 821 slides in the left card slot 82, and the card block 821 is welded to the connecting block 81. A right card slot 83 is provided on the end wall of the right card holder 6, and the right card slot 83 is connected to the connecting groove 8. A card rod 831 slides in the right card slot 83, and the card rod 831 is welded to one side of the connecting block 81. A card hole 91 is provided on the card rod 831, and a card bolt 9 is arranged in the card hole 91. A support spring 811 is welded on the side of the connecting block 81 away from the card rod 831, and the support spring 811 is welded to the right card holder 6. The clamping rod 831 is pressed, and the clamping rod 831 moves along the right clamping slot 83. The clamping rod 831 moves and drives the connecting block 81 to move in the direction of the extrusion support spring 811, so that the clamping block 821 can enter and exit the left clamping seat 5 along the connecting slot 8. After the clamping block 821 is inserted into the connecting slot 8 of the left clamping seat 5, the clamping rod 831 is released, and the support spring 811 pushes the connecting block 81 to move, so that the connecting block 81 drives the clamping block 821 to be inserted into the left clamping slot 82, and then the clamping block 821 is clamped in the left clamping slot 82, so that the left clamping seat 5 and the right clamping seat 6 are connected together. After the plurality of installation frames 4 are integrated with the left clamping seat 5 and the right clamping seat 6 and fixed in the oven, the clamping rod 831 is fixed in the oven by the clamping bolt 9, so that the clamping rod 831 is not easy to shake, and then the clamping block 821 is not easy to slide out of the left clamping slot 82.

[0036] In order to make the left card holder 5 and the right card holder 6 detachably arranged on the mounting frame 4, refer to Figures 1 to 3 , a left plug-in board 52 is integrally formed on one side of the installation frame 4, and a right plug-in board 62 is integrally formed on the other side of the installation frame 4.

The inner wall of the left slot 51, the inner wall of the right slot 61, the outer wall of the left plug-in board 52, and the outer wall of the right plug-in board 62 are all covered with a friction layer 7 made of rubber material. When the installation frame 4 is plugged into the left card holder 5 through the left plug-in board 52, the friction layer 7 increases the friction between the left slot 51 and the left plug-in block, so that the left plug-in block needs a certain external force to be removed from the left slot 51. When the installation frame 4 is plugged into the right card holder 6 through the right plug-in board 62. The friction layer 7 increases the friction between the right slot 61 and the right plug-in block, so that the right plug-in block needs a certain external force to be removed from the right slot 61. When the installation frames 4 are spliced ​​into one body and fixed in the oven, the left clamping seat 5 and the right clamping seat 6 abut between adjacent installation frames 4 , so that the left clamping seat 5 and the right clamping seat 6 are not easy to fall off the installation frames 4 .

[0037] The implementation principle of a coating oven nozzle device in the embodiment of the present application is as follows: since the aperture of the first air hole 11 is larger than the aperture of the second air hole 21, and the aperture of the second air hole 21 is larger than the aperture of the third air hole 31, the air volume blown out of the first air hole is larger than the air volume blown out of the second air hole, so the air volume blown out of the second air hole is larger than the air volume blown out of the third air hole. Therefore, the first carrier plate 1, the second carrier plate 2 and the third carrier plate 3 are arranged according to the slurry distribution on the electrode piece, the middle area of ​​the coated electrode piece corresponds to the first air hole, the transition area from the middle area to the edge area of ​​the coated electrode piece corresponds to the second air hole, and the edge area of ​​the coated electrode piece corresponds to the third air hole. When the wet coated electrode piece is dried by hot air in the oven, the hot air volume blown to the middle area of ​​the coated electrode piece is large, the hot air volume blown to the transition area of ​​the coated electrode piece is moderate, and the hot air volume blown to the convenient area of ​​the coated electrode piece is small, so that the wet coated electrode piece is evenly dried and the cracking of the edge position of the coated electrode piece is reduced.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
