Description

Technical Field

[0001] This utility model relates to the field of drying technology, specifically to a drying device. Background Technology

[0002] Currently, after coating the positive electrode slurry on the surface of the positive electrode sheet of a lithium battery to form a positive electrode slurry coating, it is usually necessary to coat ceramic slurry on both sides of the positive electrode slurry coating to form a ceramic edge. Through this ceramic edge, the burrs that puncture or scratch the separator of the lithium battery can be reduced during the cutting of the electrode tabs of the lithium battery.

[0003] Existing drying equipment typically uses an oven to heat the positive electrode slurry coating and ceramic edge of the coated positive electrode sheet to cure them. However, this method of curing the ceramic edge has several drawbacks. First, because the ceramic edge and the positive electrode slurry coating are made of different materials, they can dissolve each other under the influence of surface and volume forces. Second, due to the temperature difference between the ceramic slurry and the positive electrode slurry, the ceramic edge often cracks when heated above its required curing temperature, or it may not cure completely when heated below its required curing temperature. This can lead to the positive electrode sheet sticking to the rollers, reducing the coating quality of the positive electrode sheet.

[0004] Therefore, there is an urgent need for an improved drying device to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a drying device that can slow down the mutual dissolution of the ceramic edge of the positive electrode sheet and the positive electrode slurry coating, and can prevent the ceramic edge from cracking or not being fully cured, thereby avoiding the phenomenon of the positive electrode sheet sticking to the roller and improving the coating quality of the positive electrode sheet.

[0039] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0040] Please refer to Figures 1 to 3 An embodiment of this utility model provides a drying device, including a ceramic edge infrared drying mechanism 100 and an oven 200. The ceramic edge infrared drying mechanism 100 includes a drying chamber 10 and a plurality of infrared lamp assemblies 20.

[0041] The oven 200 has an oven inlet 201 on one side and an oven outlet (not shown in the figure) on the other side. This invention does not modify the structure of the oven 200. A drying chamber 10 is disposed on one side of the oven 200. On both sides of the drying chamber 10 are respectively provided an inlet 11 and an outlet 12 communicating with the interior of the drying chamber 10. The inlet 11 is used for the positive electrode sheet to enter the drying chamber 10, and the outlet 12 is used for the positive electrode sheet to exit the drying chamber 10. The outlet 12 corresponds to and communicates with the oven inlet 201 on one side of the oven 200. Multiple infrared lamp assemblies 20 are spaced apart along the length of the drying chamber 10 above it and are all connected to the drying chamber 10. The number of infrared lamp assemblies 20 corresponds to the ceramic edge of the positive electrode sheet. In practical applications, each infrared lamp assembly 20 corresponds to one ceramic edge of the positive electrode sheet. In this embodiment, there are four infrared lamp assemblies 20, thus this embodiment is suitable for positive electrode sheets with two positive electrode slurry coatings and four ceramic edges. The width direction of the positive electrode sheet is the same as the length direction of the drying chamber 10.

[0042] Combination Figures 4 to 9As shown, the infrared lamp assembly 20 includes a lamp holder 21, a semi-circular lamp cover 22, an infrared lamp 23, and a plano-convex focusing lens 24. The bottom end of the lamp holder 21 has a lamp holder through hole 211 communicating with the interior of the lamp holder 21. The lamp cover 22 is housed within the lamp holder 21 and fixed to the bottom of the lamp holder 21. In this embodiment, two bent members 221 are formed on both sides of the bottom end of the lamp cover 22, and the two bent members 221 are fixed to the bottom of the lamp holder 21 by means of, for example, screws. The lamp cover 22 and the two bent members 221 are integrally formed, facilitating manufacturing. The bottom and top ends of the lamp cover 22 are respectively provided with a first lamp cover through hole 222 and a second lamp cover through hole 223 communicating with the interior of the lamp cover 22. The first lamp cover through hole 222 corresponds to and communicates with the lamp holder through hole 211. When the infrared lamp 23 is powered on, it emits infrared rays. The infrared lamp 23 is housed inside the lamp cover 22. Part of the infrared lamp 23 extends out from the second lamp cover through hole 223 and is located inside and connected to the lamp holder 21. The plano-convex focusing lens 24 is fixed in the lamp cover 22 and the first lamp cover through hole 222 and rests on the bottom of the lamp holder 21. The plano-convex focusing lens 24 corresponds to the lamp holder through hole 211. In practical applications, the coated positive electrode sheet enters the drying chamber 10 through the chamber inlet 11. The infrared lamp 23 emits infrared rays, which are reflected by the semi-circular lampshade 22 and pass through the plano-convex focusing lens 24. The plano-convex focusing lens 24 focuses the divergent infrared rays into a high-energy-density light spot, which can irradiate the ceramic edge of the corresponding positive electrode sheet, thereby heating the ceramic edge of the corresponding positive electrode sheet (the heating temperature corresponds to the temperature required for the ceramic edge to solidify), so that the ceramic edge is solidified. Afterwards, the positive electrode sheet enters the drying chamber 200 through the chamber outlet 12 and the drying chamber inlet 201. The drying chamber 200 can heat the positive electrode slurry coating of the positive electrode sheet to solidify the positive electrode slurry coating. Afterwards, the positive electrode sheet comes out from the drying chamber outlet.

[0043] This invention utilizes a ceramic edge infrared drying mechanism 100, which includes a drying chamber 10 and multiple infrared lamp assemblies 20. Before the positive electrode sheet enters the drying chamber 200, the ceramic edge of the positive electrode sheet is heated by the infrared lamp assemblies 20 to solidify the ceramic edge. This reduces the phenomenon of mutual dissolution between the ceramic edge of the positive electrode sheet and the positive electrode slurry coating, and prevents the ceramic edge from cracking or being incompletely cured. This also prevents the positive electrode sheet from sticking to the roller, thus improving the coating quality of the positive electrode sheet.

[0044] In this embodiment, two guide rails 30 are provided above the drying chamber 10. The two guide rails 30 are spaced apart along the width direction of the drying chamber 10 and are both located above the multiple infrared lamp assemblies 20. One guide rail 30 is connected to the drying chamber 10 via a first support plate 31. There are two first support plates 31. Specifically, two first support plates 31 are formed at both ends of the bottom of one guide rail 30. The bottom ends of the two first support plates 31 are respectively connected to one side of the drying chamber 10. The one guide rail 30 and the two first support plates 31 are preferably integrally formed for ease of manufacturing. The other guide rail 30 is connected to the drying chamber 10 via a second support plate 32. There are two second support plates 32. Specifically, the second support plates 32 are L-shaped. Two second support plates 32 are provided at both ends of the other guide rail 30. The bottom ends of the two second support plates 32 are respectively connected to both ends of the drying chamber 10.

[0045] The infrared lamp assembly 20 also includes a connecting plate 25, which is located between the lamp holder 21 and the two guide rails 30 and connected to the lamp holder 21. The top of the connecting plate 25 is provided with two sliders 26, and the bottom of the guide rails 30 is provided with a groove 33. The two sliders 26 of the multiple infrared lamp assemblies 20 are slidably connected to the grooves 33 of the two guide rails 30 respectively.

[0046] Two fixing plates 40 are provided between the connecting plate 25 of the multiple infrared lamp assemblies 20 and the lamp holder 21 of the multiple infrared lamp assemblies 20. The two fixing plates 40 correspond to the two sliders 26 of the multiple infrared lamp assemblies 20 respectively and are detachably connected to the two guide rails 30 respectively. The top end of the fixing plate 40 abuts against the bottom end of the connecting plate 25 to press the connecting plate 25 upward. Thus, the corresponding slider 26 can be pressed against the bottom of the corresponding slide groove 33 through the connecting plate 25. In this way, the slider 26 can be fixed in the corresponding slide groove 33 to prevent the slider 26 from sliding in the corresponding slide groove 33. This can fix the infrared lamp assembly 20 and the two guide rails 30 together.

[0047] Two fixing plates 40 are detachably connected to two guide rails 30. Specifically, the fixing plates 40 are provided with fixing plate screw holes (not shown in the figure), and the top of the guide rails 30 is provided with guide rail screw holes (not shown in the figure) communicating with the slide grooves 33. Fasteners (not shown in the figure) are threaded into the guide rail screw holes of the guide rails 30 and the corresponding fixing plate screw holes of the fixing plates 40. The number of guide rail screw holes, fixing plate screw holes, and fasteners can be set according to actual conditions. The fasteners include fixing screws, which are threaded into the corresponding fixing plate screw holes and guide rail screw holes. A fixing nut is threaded onto the fixing screw, and the fixing nut abuts against the top of the guide rail 30.

[0048] The above structure allows for adjustment of the position of the infrared lamp assembly 20 to accommodate ceramic edges of varying widths. When adjusting the position of the infrared lamp assembly 20, first remove the fixing nut from the fixing screw, then remove the fixing screw from the corresponding fixing plate screw hole and guide rail screw hole. This separates the two fixing plates 40 from the two guide rails 30, and separates the top of the fixing plate 40 from the bottom of the connecting plate 25. At this point, the fixing plate 40 no longer presses against the connecting plate 25, preventing the slider 26 from being pressed against the bottom of the corresponding slide groove 33 by the corresponding connecting plate 25. The slider 26 can then slide within the corresponding slide groove 33, thus allowing the infrared lamp assembly 20 to move. Then, move multiple infrared lamp assemblies 20 to predetermined positions along the length of the drying chamber 10. Next, move the fixing plate 40 to adjust its position along the length of the drying chamber 10. Then, install the fixing screw in the corresponding fixing plate screw hole and guide rail screw hole, and make the top of the fixing plate 40 abut against the bottom of the connecting plate 25 to press the connecting plate 25 upward. In this way, the corresponding slider 26 can be pressed against the bottom of the corresponding slide groove 33 through the connecting plate 25, thus fixing the infrared lamp assembly 20 and the two guide rails 30 together, thereby preventing the infrared lamp assembly 20 from moving on its own. Then, install the fixing nut on the fixing screw and abut against the top of the corresponding guide rail 30. In this way, the position of the infrared lamp assembly 20 is adjusted.

[0049] Infrared lamp 23 is connected to lamp holder 21 via lamp clip 231. In this embodiment, lamp clip 231 has a lamp clip mounting hole at its top end, lamp holder 21 has a lamp holder mounting hole at its top end corresponding to the lamp clip mounting hole, and connecting plate 25 has a connecting plate mounting hole 251 corresponding to the lamp holder mounting hole. The lamp clip mounting hole is a threaded hole, and both the lamp holder mounting hole and the connecting plate mounting hole 251 are oblong holes. A first screw 2311 is installed in the lamp clip mounting hole, the lamp holder mounting hole, and the connecting plate mounting hole 251. The first screw 2311 is threadedly connected to a first nut 2312, which abuts against the top end of the connecting plate 25. The lamp clip 231, the connecting plate 25, and the lamp holder 21 can be connected together through the first screw 2311 and the first nut 2312.

[0050] In this embodiment, there are two lamp clips 231, which are respectively close to both ends of the infrared lamp 23. It can be understood that the number of lamp clips 231 can be set according to the actual situation. The lamp clip 231 includes a U-shaped lamp clip body 2313. The lamp clip body 2313 includes a horizontal part and two vertical parts connected to both ends of the horizontal part. The horizontal part is provided with the above-mentioned lamp clip mounting hole. Two clamping parts 2314 are formed at the ends of the two vertical parts away from the horizontal part. The two clamping parts 2314 are arranged opposite to each other. The shape of the clamping parts 2314 is adapted to the shape of the infrared lamp 23. The two clamping parts 2314 are used to clamp the infrared lamp 23. The vertical part is provided with a lamp clip threaded hole. A second screw 2315 is installed in the lamp clip threaded hole of the two vertical parts. The second screw 2315 is threadedly connected to a second nut 2316. The second nut 2316 abuts against the side of one of the vertical parts away from the other vertical plate. The structure of the lamp clip 231 facilitates the assembly of the infrared lamp 23 and the lamp clip 231. During assembly, the two clamping parts 2314 are first engaged with the infrared lamp 23, and then the second nut 2316 is tightened so that the second nut 2316 abuts against the side of one of the vertical parts away from the other vertical part. During the tightening of the second nut 2316, the end of one of the vertical parts away from the horizontal part will move towards the other vertical part under the pressure of the second nut 2316 until one of the vertical parts is tilted. When the end of one of the vertical parts away from the horizontal part moves towards the other vertical part, it can drive the corresponding clamping part 2314 to move towards the clamping part 2314 of the other vertical part, thereby reducing the distance between the two clamping parts 2314. In this way, the infrared lamp 23 can be clamped by the two clamping parts 2314, and the assembly is completed.

[0051] Inside the lamp holder 21, above the infrared lamp 23, there is a support member 213. The support member 213 supports the lamp holder 21 to prevent deformation. The support member 213 has clearance positions for avoiding the lamp clip 231. The number of clearance positions corresponds to the number of lamp clips 231.

[0052] In this embodiment, the first and second ends of the lamp holder 21 are respectively provided with a first lamp holder opening and a second lamp holder opening 214 communicating with the interior of the lamp holder 21, and the lamp holder through hole 211 is respectively connected to the first lamp holder opening and the second lamp holder opening 214. The first and second ends of the lamp cover 22 are respectively provided with a first lamp cover opening 225 and a second lamp cover opening 226, the first lamp cover opening 225 is connected to the interior of the lamp cover 22 and the interior of the lamp holder 21, the second lamp cover opening 226 is connected to the interior of the lamp cover 22 and the interior of the lamp holder 21, and the first lamp cover through hole 22 is connected to the first lamp cover opening 225 and the second lamp cover opening 226. The first end of the lamp holder 21 is provided with a sealing plate 27, and the sealing plate 27 is provided with an air inlet pipe 28. The air inlet pipe 28 is connected to the opening of the first lamp holder and is used to connect to an inflation device. Through the inflation device, cold air can be introduced into the lamp holder 21 and the lamp cover 22 via the air inlet pipe 28, the opening of the first lamp holder, and the opening of the first lamp cover 225, thereby cooling the infrared lamp 23. The air in the lamp holder 21 and the lamp cover 22 can be discharged from the opening of the second lamp cover 226 and the opening of the second lamp holder.

[0053] The sealing plate 27 is provided with a sealing plate through hole 271 communicating with the opening of the first lamp holder. One end of the infrared lamp 23 is electrically connected to a wire 232. The end of the wire 232 away from the infrared lamp 23 passes through the opening 225 of the first lamp cover, the opening of the first lamp holder, and the sealing plate through hole 271 and is used to connect to an external power source. The infrared lamp 23 can be powered by an external power source. There are two wires 232, which are the positive wire and the negative wire, respectively.

[0054] Two flexible elements 241 are respectively covered on both sides of the outer peripheral surface of the plano-convex focusing lens 24. Two lens clamping plates 242 are respectively covered on the side of the two flexible elements 241 away from the plano-convex focusing lens 24. The side of the lens clamping plate 242 away from the plano-convex focusing lens 24 abuts against the lampshade fastener 224 (e.g., a set screw) threaded onto the lampshade 22, thereby fixing the plano-convex focusing lens 24 within the lampshade 22 and the first lampshade through hole 222. The two flexible elements 241 and the two lens clamping plates 242 rest on the bottom of the lamp holder 21. The flexible elements 241 are preferably silicone or rubber parts, which protect the plano-convex focusing lens 24 and prevent damage to it. The number of lampshade fasteners 224 can be set according to actual conditions. In this embodiment, the outer peripheral surface of the lampshade 22 is provided with a screw hole communicating with the interior of the lampshade 22, and the lampshade fastener 224 is threaded into the screw hole. This structure facilitates the assembly of the plano-convex focusing lens 24 and the lamp cover 22, and also facilitates the replacement of the plano-convex focusing lens 24. During assembly, first, two flexible components 241 are respectively wrapped around both sides of the outer peripheral surface of the plano-convex focusing lens 24. Then, two lens clamping plates 242 are respectively wrapped around the sides of the two flexible components 241 away from the plano-convex focusing lens 24. Next, the plano-convex focusing lens 24, the two flexible components 241, and the two lens clamping plates 242 are placed on the bottom of the lamp holder 21. Finally, the lamp cover fastener 224 is threaded into the screw hole of the lamp cover 22, so that the lamp cover fastener 224 abuts against the corresponding lens clamping plate 242. When replacing the plano-convex focusing lens 24, first loosen the lamp cover fastener 224 to separate it from the corresponding lens pressure plate 242. Then, remove the plano-convex focusing lens 24, the two flexible parts 241, and the two lens pressure plates 242 as a whole from the lamp cover 22 and lamp holder 21. Next, remove the two lens pressure plates 242 and the two flexible parts 241 from the plano-convex focusing lens 24. Then, wrap the two flexible parts 241 around the outer periphery of the new plano-convex focusing lens 24. Next, wrap the two lens pressure plates 242 around the side of the two flexible parts 241 away from the plano-convex focusing lens 24. Then, place the new plano-convex focusing lens 24, the two flexible parts 241, and the two lens pressure plates 242 on the bottom of the lamp holder 21. Finally, tighten the lamp cover fastener 224 so that it abuts against the corresponding lens pressure plate 242. The replacement of the plano-convex focusing lens 24 is now complete.

[0055] Combination Figures 10 to 13As shown, the bottom of the drying chamber 10 is further provided with an exhaust pipe 13 that communicates with the interior of the drying chamber 10. The exhaust pipe 13 is used to connect to an air extraction device. The air extraction device can extract air from the interior of the drying chamber 10 through the exhaust pipe 13, thereby removing water vapor and NMP (N-methylpyrrolidone, 1-Methyl-2-pyrrolidinone) and other gases that evaporate during the ceramic edge heating process, so as to avoid water vapor and NMP and other gases polluting the environment.

[0056] Furthermore, the top of the drying chamber 10 is provided with a mounting hole 14 communicating with the interior of the drying chamber 10. A glass assembly 50 is placed within the mounting hole 14. Part of the glass assembly 50 is located outside the mounting hole 14 and is detachably mounted on the top of the drying chamber 10. The glass assembly 50 corresponds to multiple infrared lamp assemblies 20. In practical applications, the light spots emitted by the multiple infrared lamp assemblies 20 can simultaneously illuminate the glass assembly 50 and the ceramic edge of the corresponding positive electrode, thereby raising the temperature of the glass assembly 50. The high temperature of the glass assembly 50 reduces the condensation rate of water vapor and NMP gases evaporated during the heating process of the ceramic edge, facilitating the extraction equipment to remove water vapor and NMP gases through the exhaust pipe 13.

[0057] In this embodiment, the glass assembly 50 includes a mounting frame 51, a rectangular upper glass 52, and a rectangular lower glass 53. The top and bottom of the mounting frame 51 are open, and the mounting frame 51 is accommodated in the mounting hole 14. The top of the mounting frame 51 is bent outward to form two opposing first extensions 511 and two opposing second extensions 512. One end of each of the two second extensions 512 contacts one of the first extensions 511, and the other end of each of the two second extensions 512 contacts the other first extension 511. The two first extensions 511 and the two second extensions 512 are all located outside the mounting hole 14 and are detachably mounted on the top of the drying chamber 10, thereby fixing the mounting frame 51 and the drying chamber 10 together. The inner wall of the mounting frame 51 is provided with an annular rectangular upper glass pressure plate 513 and an annular rectangular lower glass pressure plate 514. The lower glass pressure plate 514 is located between the upper glass pressure plate 513 and the bottom of the mounting frame 51. The upper glass 52 is covered with an upper U-shaped adhesive strip 521, which is sandwiched between the upper glass pressure plate 513 and the lower glass pressure plate 514. The lower glass 53 is covered with a lower U-shaped adhesive strip 531, which is sandwiched between the lower glass pressure plate 514 and the bottom of the mounting frame 51. The U-shaped adhesive strip is made of materials such as silicone or rubber. The upper U-shaped adhesive strip 521 protects the upper glass 52 and prevents damage to it, and the lower U-shaped adhesive strip 531 protects the lower glass 53 and prevents damage to it. The use of double-glazed glass can reduce the condensation rate of water vapor and NMP gases that evaporate during the heating process of the ceramic edge, and also serve as a heat insulation function.

[0058] The above structure facilitates the replacement of the upper glass 52 and / or the lower glass 53. When replacing, for example, the upper glass 52, firstly, remove the first extension 511 and the second extension 512 from the drying chamber 10. Then, remove the entire glass assembly 50 from the mounting hole 14. Next, remove the upper glass 52 and the upper U-shaped adhesive strip 521 from the upper glass pressure plate 513 and the lower glass pressure plate 514. Then, insert the new upper glass 52, with the upper U-shaped adhesive strip 521 covering all four sides, between the upper glass pressure plate 513 and the lower glass pressure plate 514. Finally, place the entire glass assembly 50 into the mounting hole 14 and install the two first extensions 511 and the two second extensions 512 at the top of the drying chamber 10. This completes the replacement of the upper glass 52. The steps for replacing the lower glass 53 are the same as those for replacing the upper glass 52, and will not be repeated here.

[0059] Both first extensions 511 and two second extensions 512 are detachably mounted on the top of the drying chamber 10. Specifically, the first extensions 511 and second extensions 512 are respectively provided with first holes 5111 and second holes 5121. The top of the drying chamber 10 is provided with third holes and fourth holes corresponding to the first holes 5111 and second holes 5121, respectively. First mounting frame fasteners, such as screws, are installed in the third holes and the corresponding first holes 511, and second mounting frame fasteners, such as screws, are installed in the fourth holes and the corresponding second holes 512. The number of first holes 5111, second holes 5121, third holes, and fourth holes can be set according to actual conditions. The two first extensions 511 and two second extensions 512 can be disassembled and assembled by disassembling and assembling the first mounting frame fasteners and the second mounting frame fasteners.

[0060] In this embodiment, the upper glass pressure plate 513 includes two horizontal plates 5131 and two vertical plates 5132 arranged opposite to each other. The two horizontal plates 5131 are respectively disposed on the inner walls of both ends of the mounting frame 51, and the two vertical plates 5132 are respectively disposed on the inner walls of both sides of the mounting frame 51. One end of each of the two vertical plates 5132 is connected to one of the horizontal plates 5131, and the other end of each of the two vertical plates 5132 is connected to the other horizontal plate 5131.

[0061] The lower glass plate 514 includes two opposing transverse U-shaped members 5141 and two opposing longitudinal U-shaped members 5142. The two transverse U-shaped members 5141 are respectively disposed on the inner walls of both ends of the mounting frame 51, and the two longitudinal U-shaped members 5142 are respectively disposed on the inner walls of both sides of the mounting frame 51. One end of each longitudinal U-shaped member 5142 is connected to one of the transverse U-shaped members 5141, and the other end of each longitudinal U-shaped member 5142 is connected to the other transverse U-shaped member 5141.
