Description

Technical Field

[0001] The utility model relates to the technical field of coating, in particular to a laser drying oven and coating equipment. Background Art

[0002] During the lithium battery manufacturing process, the electrodes need to be dried in an oven after coating.

[0003] Existing ovens generally have upper and lower nozzles at the bottom of the upper hull and the top of the lower hull inside the box, respectively. Hot air is blown out through the upper and lower nozzles to achieve hot air heating of the electrode, thereby achieving drying of the electrode. Some ovens also have upper nozzles and an upper laser at the bottom of the upper hull, and lower nozzles and a lower laser at the top of the lower hull. Hot air is blown out through the upper and lower nozzles to achieve hot air heating of the electrode, and the upper laser and the lower laser emit lasers to achieve laser heating of the electrode, thereby achieving drying of the electrode. This method of using hot air drying has a slow drying speed, reduces drying efficiency, and increases production costs. This method of combining hot air heating and laser heating has a higher drying efficiency than the hot air drying method. However, since the temperature inside the oven box is usually relatively high during the drying process of the electrode, the temperature inside the box is usually higher than the ambient temperature when the upper laser and the lower laser are operating normally. Therefore, after a period of drying, the normal operation of the upper laser and the lower laser cannot be guaranteed, and the drying efficiency cannot be guaranteed. Utility Model Content

It can be understood that the number of upper air nozzles 31, upper laser drying components 40, lower air nozzles 32, and lower laser drying components 50 can be set according to actual conditions.

[0030] Combine Figures 8 to 11 、 Figures 17 to 19As shown, both the upper laser drying assembly 40 and the lower laser drying assembly 50 include a heat-insulating channel 41 disposed within the housing 10 and a laser 42 disposed within the inner cavity of the heat-insulating channel 41. One end of the laser 42, such as the rear end, faces the rear side of the housing 10, while the other end of the laser 42, such as the front end, faces the door 11. In this embodiment, the laser 42 is a conventional semiconductor laser, for example. The heat-insulating channel 41 provides thermal insulation.

[0031] The insulating channel 41 is a hollow structure. One end of the insulating channel 41 abuts against the rear side of the door 11, while the other end engages with the through-hole 18 on the rear side of the cabinet 10. A through-hole 111 corresponding to the insulating channel 41 is provided on the front side of the door 11, connecting the through-hole 111 to the inner cavity of the insulating channel 41. A rectangular ring-shaped fixing member 412 is formed around the outer periphery of the other end of the insulating channel 41. The fixing member 412 is located outside the cabinet 10 and is secured to the rear side of the cabinet 10 using fasteners such as screws. When the cabinet door 11 is open, one end of the insulating channel 41 is separated from the cabinet door 11.

[0032] The top of the housing 10 is provided with a U-shaped upper insulation channel support 101 and an upper hull support, and the bottom of the housing 10 is provided with a U-shaped lower insulation channel support 102 and a lower hull support. The upper insulation channel support 101 is located above the insulation channels 41 of the multiple upper laser drying assemblies 40 and is close to the front side of the housing 10. One end of the insulation channels 41 of the multiple upper laser drying assemblies 40 is disposed at the bottom end of the upper insulation channel support 101. The upper hull support is located above the upper hull 21, which is disposed at the bottom end of the upper hull support. The lower insulation channel support 102 is located below the insulation channels 41 of the multiple lower laser drying assemblies 50 and is close to the front side of the housing 10.

[0033] In actual application, the pole piece 200 enters the box body 10 from the pole piece inlet 12 of the box body 10, and passes through the multiple upper air nozzles 31, the multiple upper laser drying components 40 and the multiple lower air nozzles 32, and the multiple lower laser drying components 50, and then comes out from the pole piece outlet 13 of the box body 10. When the pole piece 200 passes through the multiple upper air nozzles 31, the multiple upper laser drying components 40 and the multiple lower air nozzles 32, and the multiple lower laser drying components 50, the hot air generated by the heating device can enter the upper hull 21 through the upper air inlet pipe and the upper air inlet 14 and enter the lower hull 22 through the lower air inlet pipe and the lower air inlet 16, and then blow toward the upper surface and the lower surface of the pole piece 200 through the multiple upper air nozzles 31 and the multiple lower air nozzles 32 to heat the pole piece 200 with hot air. At the same time, after the lasers 42 of the multiple upper laser drying components 40 and the lasers 42 of the multiple lower laser drying components 50 are powered on, the lasers 42 of the multiple upper laser drying components 40 and the lasers 42 of the multiple lower laser drying components 50 can respectively irradiate the upper surface and the lower surface of the electrode 200 with lasers to perform laser heating on the electrode 200, thereby achieving the drying of the electrode 200. A part of the mixture of the hot air after drying the electrode 200 and the NMP vapor, water vapor, etc. evaporated during the drying process of the electrode 200 can be discharged through the exhaust port 15, and the remaining part flows back to the heating equipment through the return air port 17. After filtering the NMP vapor, this part can be heated again by the heating equipment, thereby achieving recycling. The present invention achieves drying of the electrode 200 by combining hot air heating and laser heating, which can achieve rapid drying of the electrode 200, improve drying efficiency, and reduce production costs. The heat insulation channel 41 provided can play a heat insulation role, thereby preventing the heat in the box 10 from being transferred to the laser 42, ensuring that the ambient temperature of the laser 42 is within the ambient temperature range when the laser 42 is operating normally, thereby ensuring that the laser 42 can operate normally and ensuring the drying efficiency. The temperature inside the box 10 is usually around 100°C, and the ambient temperature when the laser 42 is operating normally is usually 10°C-45°C. The heat insulation channel 41 of this embodiment can ensure that the temperature inside the inner cavity of the heat insulation channel 41 is around 40°C.

The cover plate 113 is evenly distributed with a number of air outlet holes 1131, such as Figure 1As shown, several air outlet holes 1131 are connected to the through hole 111. The number of air outlet holes 1131 can be set according to actual conditions. A hood 60 is provided on the rear side of the housing 10. The fixing member 412 is located within the hood 60. The inner cavity of the heat insulation channel 41 is connected to the interior of the hood 60. An air inlet pipe 61 is provided at the bottom end of the hood 60. The air inlet pipe 61 is connected to the interior of the hood 60. The end of the air inlet pipe 61 away from the hood 60 is connected to the ventilation fan 70. In actual use, indoor air is introduced into the inner cavity of the heat-insulating channel 41 by the ventilation fan 70 through the air inlet pipe 61 and the air hood 60, thereby maintaining a positive pressure in the inner cavity of the heat-insulating channel 41. This prevents NMP (N-methylpyrrolidone, 1-Methyl-2-pyrrolidinone) vapor, such as that evaporated during the drying process of the electrode 200 in the housing 10, from flowing into the inner cavity of the heat-insulating channel 41 and coming into contact with the powered laser 42. This prevents the NMP vapor from reaching its flash point, thus providing explosion protection and improving the safety performance of the equipment. After entering the inner cavity of the heat-insulating channel 41, the air can flow out of the housing 10 through the through-hole 111 corresponding to the heat-insulating channel 41 and the plurality of air outlet holes 1131 of the cover plate 113.

[0035] The cover 113 is transparent and made of, for example, acrylic. This transparent cover facilitates observation of the operating status of the laser 42 through the indicator lights on the front of the laser 42 during operation. The indicator lights on the front of the laser 42 include a power indicator, a normal operation indicator, a fault indicator, and a network connection indicator.

[0036] A channel sealing ring 411 is provided at one end of the heat-insulating channel 41.

The channel sealing ring 411 is rectangular in shape and is provided to perform a sealing function.

[0037] An air hood sealing ring is provided between the air hood 60 and the rear side of the box body 10, and the air hood sealing ring plays a sealing role.

The distal end of the first water outlet connector 821 extends through a third through-hole at the top of the hood 60 and is located above the hood 60.

The ends of the water outlet pipes 422 of the lasers 42 of the multiple lower laser drying components 50 extend from the corresponding heat insulation channels 41 and are connected to the corresponding third water outlet joints 823. In actual application, the cooling water of the cooling water circulation system can enter the water inlet main pipe 81 through the water outlet of the cooling water circulation system and the first water inlet joint 811, and then enter the water inlet pipes 421 of the lasers 42 of the multiple upper laser drying components 40 and the water inlet pipes 421 of the lasers 42 of the multiple lower laser drying components 50 through multiple second water inlet joints 812 and multiple third water inlet joints 813 respectively, and then enter the cooling channels in the lasers 42 of the multiple upper laser drying components 40 through the water inlets 42a of the lasers 42 of the multiple upper laser drying components 40 and the cooling channels in the lasers 42 of the multiple lower laser drying components 50 through the water inlets 42a of the lasers 42 of the multiple lower laser drying components 50, and then enter the cooling channels in the lasers 42 of the multiple lower laser drying components 50 through the multiple The water outlet 42b of the laser 42 of the upper laser drying assembly 40 enters the water outlet pipes 422 of the lasers 42 of the multiple upper laser drying assemblies 40 and the water outlet 42b of the lasers 42 of the multiple lower laser drying assemblies 50 enters the water outlet pipes 422 of the lasers 42 of the multiple lower laser drying assemblies 50, and then enters the water outlet main pipe 82 through the multiple second water outlet joints 822 and the multiple third water outlet joints 823, and then flows back to the cooling water circulation system through the first water outlet joint 821 and the water inlet of the cooling water circulation system.

Fasteners 41713, such as screws, are installed in the first and corresponding second mounting holes 4181. The number of first and second mounting holes 4181 can be adjusted based on actual needs. A rectangular, ring-shaped second mounting portion 41712 is formed at the other end of the mounting member 4171. The second mounting portion 41712 is located within the opening 416 and adjacent to the inner cavity of the thermal insulation channel 41. Four U-shaped first pressing blocks 4172 and four L-shaped second pressing blocks 4173 are welded to the four inner walls of the mounting member 4171, respectively. The four first pressing blocks 4172 are joined end-to-end, and the four second pressing blocks 4173 are joined end-to-end. The four first pressing blocks 4172 are positioned between the four second pressing blocks 4173 and the second mounting portion 41712. One end of the second pressing block 4173 facing the pole piece 200 is flush with the side of the first mounting portion 41711 facing the pole piece 200. The first glass 4174 is sandwiched between the four first pressing blocks 4172 and the second mounting portion 41712, and the second glass 4175 is sandwiched between the four second pressing blocks 4173 and the four first pressing blocks 4172. In actual application, the laser light emitted by the laser 42 can pass through the first glass 4174 and the second glass 4175. The first glass 4174 and the second glass 4175 can ensure the heat insulation effect and prevent condensation caused by the large difference between the temperature in the inner cavity of the heat insulation channel 41 and the temperature in the box 10. By disassembling the fastener 41713, the first mounting portion 41711 can be disassembled, and the entire light-transmitting structure 417 can be removed from the corresponding heat insulation channel 41. The sealing strip 418 can play a sealing role.

[0046] The mounting member 4171 , the four first mounting portions 41711 and the second mounting portion 41712 are an integrally formed structure, and the integrally formed structure is Z-shaped.

[0047] Furthermore, both surfaces of the first glass 4174 and the second glass 4175 are coated with an antireflection film. The antireflection film can increase the transmittance of the laser light to >99.5%, thereby improving the drying efficiency of the electrode 200. The thickness of the antireflection film is 930nm-940nm (nanometers).

[0048] In this embodiment, the first glass 4174 and the second glass 4175 are both iridescent glass, and are formed by splicing together multiple, for example, three, rectangular sub-glasses. The mounting member 4171, the first pressing block 4172, and the second pressing block 4173 are all sheet metal parts.

[0049] Furthermore, two L-shaped pads 413 are provided in the inner cavity of the heat-insulating channel 41 and are symmetrically arranged. Specifically, the two L-shaped pads 413 of the upper laser drying assembly 40 are respectively arranged on the inner wall of the inner cavity of the heat-insulating channel 41 of the upper laser drying assembly 40 away from the upper hull 21, as shown in FIG. Figure 8 As shown, the two L-shaped pads 413 of the lower laser drying assembly 50 are respectively positioned on the inner wall of the insulation channel 41 of the lower laser drying assembly 50, near the lower hull 22. The length of the L-shaped pads 413 is aligned with the length of the insulation channel 41. A light-transmitting structure 417 is located between the two L-shaped pads 413. The laser 42 is placed on the two L-shaped pads 413, specifically on the horizontal portions of the two L-shaped pads 413. The vertical portions of the two L-shaped pads 413 contact the sides of the laser 42, providing support for the laser 42. By placing the laser 42 on the two L-shaped pads 413, the laser 42 is positioned within the insulation channel 41. To actually position the laser 42 within the insulation channel 41, the laser 42 can be simply pushed from one end of the insulation channel 41 along the two L-shaped pads 413 into the insulation channel 41.

[0050] The L-shaped pad 413 is a Teflon pad with a low friction coefficient. When the laser 42 is pushed into the inner cavity of the heat insulation channel 41 along the two L-shaped pads 413, the friction between the laser 42 and the pad can be reduced, thereby avoiding damage to the laser 42.

[0051] Understandably, if Figure 8 and Figure 13As shown, a support pad 4131 for supporting the laser 42 may also be provided within the inner cavity of the heat-insulating channel 41 of the upper laser drying assembly 40 between the two L-shaped pads 413, depending on actual circumstances. For example, the support pad 4131 of the upper laser drying assembly 40 is provided on the inner wall of the heat-insulating channel 41 of the upper laser drying assembly 40 away from the upper hull 21. A support pad 4131 for supporting the laser 42 may also be provided within the inner cavity of the heat-insulating channel 41 of the lower laser drying assembly 50 between the two L-shaped pads 413, depending on actual circumstances. For example, the support pad 4131 of the lower laser drying assembly 50 is provided on the inner wall of the heat-insulating channel 41 of the lower laser drying assembly 50 near the lower hull 22. The number and shape of the support pads 4131 may be set according to actual circumstances, and the material of the support pads 4131 is the same as that of the L-shaped pads 413. The support pad 4131 and the L-shaped pad 413 are provided to create a space between the laser 42 and the light-transmitting structure 417. After the air is input into the inner cavity of the heat-insulating channel 41, the air can flow between the laser and the light-transmitting structure 417, so that one side of the light-transmitting structure 417 can maintain positive pressure.

[0052] Furthermore, an L-shaped limit block 414 for limiting the laser 42 is provided in the inner cavity of the heat-insulating channel 41 behind the laser 42. The laser 42 abuts against the limit block 414. Specifically, the limit block 414 of the upper laser drying assembly 40 is provided on the inner wall of the inner cavity of the heat-insulating channel 41 of the upper laser drying assembly 40 away from the upper hull 21, as shown in FIG. Figure 9 、 Figure 11 、 Figure 13 As shown, the limit block 414 of the lower laser drying assembly 50 is set on the inner wall of the inner cavity of the heat insulation channel 41 of the lower laser drying assembly 50 away from the lower hull 22, as shown in FIG. Figure 18 As shown, the stopper 414 is provided to limit the position of the laser 42 as it is pushed from one end of the heat-insulating channel 41 along the two L-shaped pads 413 into the inner cavity of the heat-insulating channel 41. In this embodiment, there are two stoppers 414. It is understood that the shape and number of the stoppers 414 can be set according to actual conditions.

[0053] In this embodiment, Figures 8 to 14 、 Figures 17 to 19 As shown, the heat-insulating channel 41 includes a hollow outer shell 41a and a hollow inner liner 41b.

The sealed connection is, for example, welding. A heat-insulating cavity 41e is formed between the inner liner 41b and the inner wall of the outer shell 41a. Figure 11 and Figure 12As shown, the insulation cavity 41e is filled with cold gel, and the interior of the liner 41b of the insulation channel 41 forms the inner cavity of the insulation channel 41. The insulation channel 41 adopts a double-layer structure formed by the outer shell 41a and the inner liner 41b, which provides thermal insulation. The cold gel filled in the insulation cavity 41e further provides thermal insulation and can ensure that the temperature in the inner cavity of the insulation channel 41 is around 40°C.

[0054] One end of the outer shell 41a, the first connecting member 41c, and one end of the inner liner 41b are provided with the above-mentioned channel sealing ring 411, so that one end of the outer shell 41a, the first connecting member 41c, and one end of the inner liner 41b are abutted against the rear side of the door 11 through the above-mentioned channel sealing ring 411, and the other end of the outer shell 41a is matched with the through hole 18 on the rear side of the box body 10. The outer periphery of the second connecting member 41d is formed with the above-mentioned fixing member 412, and the fixing member 412 and the second connecting member 41d are an integral part. An annular sealing member is provided between the other end of the outer shell 41a and the inner wall of the through hole 18 for sealing, and the sealing member is sleeved on the outer periphery of the other end of the outer shell 41a. One end of the outer shell 41a of the multiple upper laser drying components 40 is set at the bottom end of the upper thermal insulation channel bracket 101, and one end of the outer shell 41a of the multiple lower laser drying components 50 is set at the top end of the lower thermal insulation channel bracket 102. A first rectangular hole and a second rectangular hole are provided on the side of the outer shell 41a facing the pole piece 200 and on the side of the inner liner 41b facing the pole piece 100. A third connecting member 41g is provided in the first hole and the second hole. The third connecting member 41g is arranged on the four inner walls of the first hole and the four inner walls of the second hole by welding. The side of the third connecting member 41f facing the pole piece 100 is provided with the above-mentioned groove 415, and the bottom of the groove 415 is provided with the above-mentioned opening 416.

[0055] A connecting column 41f and a reinforcing plate are provided between the inner wall of the inner container 41b and the outer shell 41a. Figure 11 As shown, the provided connecting column 41f and the reinforcing plate support the outer shell 41a, thereby preventing the outer shell 41a from collapsing and deforming.

[0056] The outer shell 41a, the inner shell 41b, the fixing member 412, the first connecting member 41c, and the second connecting member 41d are all sheet metal parts, and the channel sealing ring 411, the air cover sealing ring, the sealing strip 418, and the sealing members are all made of materials such as silicone, rubber, etc.
