Description

Technical Field

[0001] The present invention relates to the technical field of composite solid electrolyte membrane production, and particularly to a device for manufacturing a composite solid electrolyte membrane. Background Art

[0002] With the progress of the times, traditional liquid batteries and colloidal batteries can no longer meet the special equipment supporting requirements of some industries due to relatively poor energy density and safety. Solid-state batteries are a new type of battery with good safety and high energy density. Theoretically, solid-state batteries are completely suitable for equipment supporting in all industries.

[0003] When the existing composite solid electrolyte membrane is produced, it is necessary to coat a composite electrolyte slurry on a support membrane, then press the support membrane together with siliconized paper, and then pre-dry it to solidify the electrolyte slurry. Then, a composite electrolyte slurry is coated on the other side of the support membrane and dried again. However, a series of existing processes such as coating and drying are carried out separately, resulting in discontinuous production, low production efficiency, large floor area due to multiple processing equipment, and high production costs.

[0004] Based on this, we propose a device for manufacturing a composite solid electrolyte membrane. Summary of the Invention

[0040] The coating mechanism further includes two fourth mounting plates 17 symmetrically and fixedly connected to the upper end of the base 1. A second coating roller 18 is rotatably connected to the mutually approaching side walls of the two fourth mounting plates 17. The upper end of the base 1 is fixedly connected to a second coating plate 19 through a fixed shaft. A second feed cavity 20 is formed in the second coating plate 19, and a plurality of second spraying holes 21 are formed in the inner wall of the second feed cavity 20.

[0041] The pressing mechanism includes two fifth mounting plates 55 symmetrically and fixedly connected to the upper end of the base 1. Two pressing rollers 56 are rotatably connected to the mutually approaching side walls of the two fifth mounting plates 55.

[0042] The driving mechanism includes a motor 22 fixedly connected to the side wall of the base 1 through a bracket. The output end of the motor 22 penetrates through the second mounting plate 10 and is fixedly connected to the winding roller 11. A driving wheel 23 is fixedly connected to the side wall of the output end of the motor 22. One end of the first unwinding roller 3 penetrates through the side wall of the first mounting plate 2 and is fixedly connected to a first driven wheel 24. One end of the second unwinding roller 5 penetrates through the side wall of the box body 4 and is fixedly connected to a second driven wheel 25. The driving wheel 23, the first driven wheel 24 and the second driven wheel 25 are connected through a synchronous belt.

[0043] A pump feeding mechanism is installed on the base 1. The pump feeding mechanism includes a sliding cylinder 26 fixedly connected to the upper end of the base 1 through a fixed shaft. A sliding plug 27 is hermetically and slidably connected to the inner wall of the sliding cylinder 26 (as shown in Figure 7 ) and a one-way feeding pipe 28 is fixedly connected to the side wall of the sliding cylinder 26 (as shown in Figure 2As shown in the figure, the other end of the one-way feed pipe 28 is communicated with a container storing the composite electrolyte slurry externally, and the one-way feed pipe 28 only allows the external composite electrolyte slurry to enter the sliding cylinder 26. The sliding cylinder 26 is communicated with the first feed cavity 15 through the first one-way discharge pipe 29, and the sliding cylinder 26 is communicated with the second feed cavity 20 through the second one-way discharge pipe 30. The first one-way discharge pipe 29 and the second one-way discharge pipe 30 only allow the composite electrolyte slurry in the sliding cylinder 26 to enter the first feed cavity 15 and the second feed cavity 20 respectively. A push rod 31 is fixedly connected to the side wall of the sliding plug 27. One end of the push rod 31 penetrates through the side wall of the sliding cylinder 26. A first cam 33 is fixedly connected to the side wall of the second material release roller 5. One end of the push rod 31 is in sliding contact with the side wall of the first cam 33. A first spring 32 is sleeved on the side wall of the push rod 31. Two ends of the first spring 32 are respectively fixedly connected to the inner wall of the sliding cylinder 26 and the side wall of the sliding plug 27.

[0044] Further, start the motor 22 to drive the winding roller 11 to rotate, and the motor 22 will synchronously drive the driving wheel 23 to rotate, thereby driving the first driven wheel 24 and the second driven wheel 25 to rotate, driving the first material release roller 3 and the second material release roller 5 to rotate. The rotation of the winding roller 11 will wind the composite electrolyte film, and the rotation of the first material release roller 3 and the second material release roller 5 will release the silicon oil paper and the support film. Then the whole device starts to operate. The rotation of the second material release roller 5 will drive the first cam 33 to rotate. Then the first cam 33 cooperates with the first spring 32 to drive the push rod 31 to slide reciprocally, driving the sliding plug 27 to slide reciprocally for sealing. At this time, the external composite electrolyte slurry will be pumped into the sliding cylinder 26 through the one-way feed pipe 28. Then the composite electrolyte slurry will enter the first feed cavity 15 and the second feed cavity 20 through the first one-way discharge pipe 29 and the second one-way discharge pipe 30 respectively. The composite electrolyte slurry will be sprayed onto the A side of the silicon oil paper through a plurality of first spraying holes 16, and then enter the preheating box 6 for drying. Subsequently, the B side of the silicon oil paper is sprayed, and after drying again, it is wound. Spraying, pressing, drying, and winding are automatically completed integrally, with good production continuity and higher efficiency. And it can greatly reduce the floor area of the equipment and lower the production cost.

[0045] A drying mechanism is installed on the preheating box 6. The drying mechanism includes a first sliding groove 34 opened on the inner wall of the preheating box 6 (as Figure 9 shown). The first sliding groove 34 penetrates through the side wall of the preheating box 6. A sliding rod 35 is slidably connected to the inner wall of the first sliding groove 34. A drying plate 36 is fixedly connected to the side wall of the sliding rod 35. An air inlet cavity 37 is opened in the drying plate 36. A plurality of air spraying holes 38 are opened on the inner wall of the air inlet cavity 37. The air spraying holes 38 are arranged in four rows, and the two rows of air spraying holes 38 on both sides are symmetrically arranged. An air pump 39 is fixedly connected to the upper end of the drying plate 36. The air pump 39 is communicated with the air inlet cavity 37 through a plurality of air supply pipes 40. The air pump 39 is communicated with a container storing hot air externally through a pipeline.

[0046] The drying mechanism further includes four stoppers 41 slidably connected in the air inlet chamber 37 (as Figure 5 shown), and a plurality of second springs 42 are fixedly connected between two adjacent stoppers 41. Two rotating shafts 43 are symmetrically and rotatably connected to the inner wall of the air inlet chamber 37. Second cams 44 are fixedly connected to the side walls of the two rotating shafts 43. The side wall of the stopper 41 is in sliding contact with the second cam 44. The protruding parts of the two second cams 44 are arranged in opposite directions. One end of the rotating shaft 43 penetrates through the first chute 34 and is fixedly connected to a first gear 45. The upper end of the base 1 is fixedly connected to a first rack 46 through a fixed shaft. The first gear 45 is meshed with the first rack 46, and the sliding rod 35 and the push rod 31 are fixedly connected through a fixed rod.

[0047] It should be noted that the four stoppers 41 are grouped in pairs, and the second cam 44 is located between a pair of stoppers 41 (as Figure 5 shown).

[0048] It should be noted that the number of rows of the air jet holes 38 is the same as the number of the stoppers 41, and the air jet holes 38 are not in a uniform matrix. When the push rod 31 extends to the limit, the states of the stoppers 41 and the air jet holes 38 are as Figure 5 shown. At this time, two rows of the air jet holes 38 that are close to each other are completely blocked by the corresponding two stoppers 41, and the two rows of the air jet holes 38 that are far from each other are completely exposed.

[0049] It should be noted that by setting the transmission ratio between the first gear 45 and the first rack 46, when the drying plate 36 reciprocates, the rotating shaft 43 can only rotate forward and backward by 180 degrees.

[0050] Further, the air pump 39 pumps the external hot air into the intake cavity 37 through the air supply pipe 40. Finally, the hot air is ejected through multiple air ejection holes 38 to dry the composite electrolyte slurry on the composite electrolyte membrane. When the drying plate 36 moves towards the drying box 7, it drives the rotating shaft 43 to move synchronously, driving the first gear 45 to move. Since the first gear 45 meshes with the first rack 46, the first gear 45 rotates synchronously, driving the rotating shaft 43 to rotate, and then driving the second cam 44 to rotate, causing the two stoppers 41 on both sides to move towards both sides, and the two stoppers 41 in the middle also move towards both sides. As a result, the two rows of air ejection holes 38 on both sides will gradually be blocked by the stoppers 41, while the two rows of air ejection holes 38 in the middle will gradually open. Therefore, during the movement of the drying plate 36 towards the drying box 7, the number of air ejection holes 38 increases, and the diameter of the air ejection holes 38 decreases. Thus, the air ejection speed can be gradually increased. On the contrary, the air ejection speed is small when moving away from the drying box 7. Since the composite electrolyte slurry has a large fluidity at the beginning, a small air ejection speed at the beginning can prevent the composite electrolyte slurry from flowing, thereby avoiding unevenness of the composite electrolyte slurry on the composite electrolyte membrane. As the drying progresses, the composite electrolyte slurry gradually solidifies and its fluidity decreases. Therefore, the closer the composite electrolyte slurry is to the drying box 7, the smaller its fluidity. So when the drying plate 36 approaches the drying box 7, the air ejection speed increases, which can improve the drying speed.

[0051] A leveling mechanism is installed on the drying plate 36. The leveling mechanism includes a leveling plate 47 fixedly connected to the side wall of the drying plate 36 through a fixed shaft. The leveling plate 47 is U-shaped. Two leveling blocks 48 are symmetrically and slidably connected to the inner wall of the leveling plate 47. Two reciprocating lead screws 49 are symmetrically and rotatably connected to the inner wall of the leveling plate 47. The side walls of the two reciprocating lead screws 49 are respectively threadedly connected to the two leveling blocks 48. Two second chutes 50 are opened on the side wall of the preheating box 6. One end of each of the two reciprocating lead screws 49 penetrates through the second chute 50 and is fixedly connected to two second gears 51. Two second racks 52 are fixedly connected to the upper end of the base 1 through a fixed shaft. The two second gears 51 are respectively meshed with the two second racks 52.

[0052] Further, the composite electrolyte membrane entering the preheating box 6 passes through between the leveling plates 47. The reciprocating movement of the push rod 31 drives the sliding rod 35 to reciprocate, and then drives the drying plate 36 to reciprocate, driving the leveling plate 47 to reciprocate to level the composite electrolyte membrane. There may be wrinkles on the surface of the composite electrolyte membrane just after pressing. And when the leveling plate 47 reciprocates, it drives the reciprocating lead screw 49 to translate, and then drives the second gear 51 to translate. Since the second gear 51 meshes with the second rack 52, the second gear 51 rotates synchronously, and then drives the reciprocating lead screw 49 to rotate, causing the two leveling blocks 48 to move back and forth, further improving the effect of eliminating wrinkles.

[0053] On the side walls of the two first mounting plates 2 and the two third mounting plates 12 that are close to each other, a first guide roller 53 is rotatably connected in common. Inside the box body 4, a first guide roller 53 is rotatably connected. Inside the drying box 7, a plurality of second guide rollers 54 are rotatably connected. At the top inside the drying box 7, a ceramic infrared heater 57 is installed.

[0054] In the present invention, silicon oil paper is wound around the first feeding roller 3, and a support film is wound around the second feeding roller 5. The silicon oil paper sequentially passes around the first guide roller 53, the first coating roller 13, the pressing roller 56, the second coating roller 18, and the guide roller 9, and then the end is fixed to the winding roller 11. The support film sequentially passes around the first guide roller 53, the pressing roller 56, and the guide roller 9, and then the end is fixed to the winding roller 11, and the support film is located above the silicon oil paper (as Figure 3 shown).

[0055] Then, start the motor 22, the air pump 39, and the ceramic infrared heater 57 to drive the winding roller 11 to rotate. And the motor 22 will synchronously drive the driving wheel 23 to rotate, and then drive the first driven wheel 24 and the second driven wheel 25 to rotate, driving the first feeding roller 3 and the second feeding roller 5 to rotate. The rotation of the winding roller 11 will wind up the electrolyte membrane, and the rotation of the first feeding roller 3 and the second feeding roller 5 will feed the silicon oil paper and the support film. Then the whole device starts to operate. The rotation of the second feeding roller 5 will drive the first cam 33 to rotate. Then the first cam 33 cooperates with the first spring 32 to drive the push rod 31 to slide reciprocally, driving the sliding plug 27 to slide reciprocally for sealing. At this time, the external composite electrolyte slurry will be pumped into the sliding cylinder 26 through the one-way feeding pipe 28. Then the composite electrolyte slurry will enter the first feeding cavity 15 and the second feeding cavity 20 through the first one-way discharging pipe 29 and the second one-way discharging pipe 30 respectively. The composite electrolyte slurry will be sprayed onto the A side of the silicon oil paper through a plurality of first spraying holes 16. Then when the silicon oil paper and the support film pass between the two pressing rollers 56, the silicon oil paper and the support film are pressed together, and then enter the preheating box 6 together.

[0056] The composite electrolyte membrane entering the preheating box 6 will pass through between the leveling plates 47. The reciprocating movement of the push rod 31 will drive the sliding rod 35 to move reciprocally, and then drive the drying plate 36 to move reciprocally, driving the leveling plates 47 to move reciprocally to level the composite electrolyte membrane. There may be wrinkles on the surface of the just-pressed composite electrolyte membrane. And when the leveling plates 47 move reciprocally, they will drive the reciprocating lead screw 49 to translate, and then drive the second gear 51 to translate. Since the second gear 51 meshes with the second rack 52, the second gear 51 will rotate synchronously, and then drive the reciprocating lead screw 49 to rotate, causing the two leveling blocks 48 to move back and forth, further improving the effect of eliminating wrinkles.

[0057] The air pump 39 pumps the external hot air into the air inlet cavity 37 through the air supply pipe 40. Finally, the hot air is ejected through a plurality of air ejection holes 38 to dry the composite electrolyte slurry on the composite electrolyte membrane. When the drying plate 36 moves towards the drying box 7, it drives the rotating shaft 43 to move synchronously, driving the first gear 45 to move. Since the first gear 45 meshes with the first rack 46, the first gear 45 rotates synchronously, driving the rotating shaft 43 to rotate, and then driving the second cam 44 to rotate, causing the two stoppers 41 on both sides to move towards both sides, and the two stoppers 41 in the middle also move towards both sides. As a result, the two rows of air ejection holes 38 on both sides are gradually blocked by the stoppers 41, while the two rows of air ejection holes 38 in the middle are gradually opened. Therefore, during the process of the drying plate 36 moving towards the drying box 7, the number of air ejection holes 38 increases, and the diameter of the air ejection holes 38 decreases. Thus, the air ejection speed can be gradually increased. On the contrary, when moving away from the drying box 7, the air ejection speed is small. Since the composite electrolyte slurry has a large fluidity at the beginning, a small air ejection speed at the beginning can prevent the composite electrolyte slurry from flowing, thereby avoiding uneven composite electrolyte slurry on the composite electrolyte membrane. As the drying progresses, the composite electrolyte slurry gradually solidifies and its fluidity decreases. Therefore, the closer the composite electrolyte slurry is to the drying box 7, the smaller its fluidity. So when the drying plate 36 moves towards the drying box 7, the air ejection speed increases, which can improve the drying speed.

[0058] After the composite electrolyte membrane moves out of the preheating box 6, a plurality of second slurry spraying holes 21 spray the composite electrolyte slurry on the B side of the silicon oil paper. Subsequently, it enters the drying box 7, and the ceramic infrared heater 57 dries it again. Finally, a complete composite electrolyte membrane is formed, and then it is wound on the take-up roller 11.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
