Description

Technical Field

[0001] This invention relates to the field of lithium battery manufacturing technology, specifically to a drying device with a flipping structure. Background Technology

[0002] Lithium battery drying equipment is an important part of the manufacturing process of lithium-ion batteries. During the manufacturing process, it is necessary to dry the liquid or wet materials in the battery components to ensure the quality and performance of the batteries.

[0003] Patent publication number CN214039343U relates to a lithium battery drying device, comprising: a frame; a rotating mechanism disposed within the inner cavity of the frame; several microwave heaters, each fixedly installed on the inner wall of the frame; a fan fixedly installed on the top right side of the frame; a filter box fixedly installed on the top left side of the frame; an air outlet pipe, one end of which is fixedly connected to the air outlet of the fan, and the other end extending into the inner cavity of the frame; an air inlet pipe, one end of which is fixedly inserted into the left side of the filter box, and its bottom end extending into the inner cavity of the frame; an air inlet hopper fixedly installed at the bottom end of the air inlet pipe; and a filtration mechanism disposed within the inner cavity of the filter box. This patent solves the problems of lithium battery drying devices failing to heat lithium batteries evenly, resulting in longer equipment operating times, and the inability to clean dust from the equipment.

[0004] In the aforementioned patent, a motor drives the active pulley, driven pulley, first rotating column, and turntable to rotate. With the cooperation of gears and gear rings, the second rotating column can rotate while rotating, causing the roller to drive the placement rack to rotate, thus ensuring uniform heating of the lithium battery. However, in actual use, because the air inlet blows hot air from above to dry the lithium battery, the upper part of the lithium battery is in closer contact with the hot air, resulting in the upper part of the lithium battery drying faster than the lower part. This leads to uneven drying efficiency between the upper and lower parts of the lithium battery, which in turn affects the function of the lithium battery. Therefore, a lithium battery drying device with a flipping structure is designed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a drying device with a flipping structure, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drying device with a flipping structure, comprising a drying chamber, a flipping device, and a fixing device; wherein a dryer is fixedly installed on the bottom inner wall of the drying chamber, a motor is fixedly installed on the bottom inner wall of the drying chamber, and an installation plate is fixedly installed inside the drying chamber, with ventilation grooves formed on the surface of the installation plate; wherein the flipping device comprises a rotating disk, a drying frame, a rotating disc, a connecting disc, a connecting rod, and a fixing rod, the output end of the motor rotates to drive the rotating disk to rotate, the rotating disk rotates to drive the drying frame to rotate, the rotating drying frame rotates to drive the connecting disc to move, the moving connecting disc moves the connecting rod, the rotating disk is fixedly installed on the output end of the motor, and the drying frame is fixedly installed on the rotating disk.

Gear 3 is fixedly installed at the end of the connecting rod away from the connecting disk, and gear 4 is fixedly installed on the surface of the fixing rod. Gear 3 and gear 4 mesh. The rotation of the rotating disk realizes the flipping of the lithium battery, making the upper and lower surfaces of the lithium battery more evenly contacted with the hot air, thus improving the drying effect of the lithium battery.

[0007] According to the above technical solution, a striking rod is fixedly installed at the end of the connecting rod away from the fixed rod, and a filter plate is fixedly installed on the surface of the drying frame. The striking rod is elastic, and the rotation of the connecting rod drives the striking rod to rotate. The rotating striking rod strikes the filter plate, effectively removing dust from the surface of the filter plate and preventing dust residue on the surface of the filter plate from causing blockage and affecting the drying effect.

[0008] According to the above technical solution, the fixing device includes a slider, a clamping plate, and a triangular block. The lithium battery moves and contacts the slider, causing it to move. After the slider moves, it resets and drives the clamping plate to move. The clamping plate moves and contacts the lithium battery, clamping it. The slider is slidably mounted on the surface of the rotating disk, and the clamping plate is slidably mounted on the surface of the slider. A second groove is provided on the surface of the slider. The triangular block is slidably mounted inside the second groove. A spring is provided at the junction of the slider and the rotating disk. The clamping plate and the slider are fixedly connected by an elastic telescopic rod. The triangular block is fixedly connected to the inner wall of the second groove by the elastic telescopic rod. When the clamping plate moves and contacts the lithium battery, it is squeezed and drives the triangular block to move. After the triangular block moves, it resets under the action of the elastic telescopic rod, limiting and fixing the triangular block to prevent the lithium battery from detaching from the rotating disk during rotation. At the same time, it can prevent excessive clamping force from damaging the lithium battery.

[0009] According to the above technical solution, a fixing plate is fixedly installed on the surface of the rotating disk. A groove three is formed on the surface of the fixing plate. A clamping plate is slidably installed inside the groove three. A groove four is formed on the surface of the clamping plate. A blocking block is slidably installed inside the groove four. A spring-loaded spring two is provided at the junction of the clamping plate and the groove three. The surface of the blocking block is cut into a bevel. The blocking block is fixedly connected to the inner wall of the groove four by an elastic telescopic rod three. When the clamping plate moves upward, it drives the blocking block to move upward and is limited by the fixing plate. This can effectively clamp lithium batteries of different thicknesses and improve the applicability of the drying equipment.

[0010] According to the above technical solution, it also includes a dehumidification device and a fire prevention device. The dehumidification device includes a lifting rod, an arc-shaped block, a rotating shaft, a stop block, and a rotating plate. The fixed plate rotates and contacts the lifting rod, causing it to move upward. The upward movement of the lifting rod drives the arc-shaped block to move upward. The arc-shaped block moves upward and contacts and drives the stop block to rotate. The rotation of the stop block drives the rotating shaft to rotate. The lifting rod is slidably installed on the surface of the drying frame. A five-slide groove is provided on the surface of the lifting rod. The arc-shaped block is slidably installed inside the five-slide groove. The rotating shaft rotates through the inner and outer walls of the drying frame. The stop block is fixedly installed on the surface of the rotating shaft. The rotating plate is fixedly installed on the surface of the rotating shaft. The arc-shaped block and the inner wall of the five-slide groove are fixedly connected by an elastic telescopic rod. The lower part of the lifting rod is curved. A spring-loaded spring is provided at the junction of the lifting rod and the drying frame. The rotation of the rotating shaft drives the rotating plate to rotate. The rotation of the rotating plate discharges the air inside the drying frame, improving the air circulation between the inside and outside of the drying frame, preventing humid air from remaining inside the drying frame and affecting the subsequent drying of the lithium battery, thus improving the drying effect.

[0011] According to the above technical solution, a lifting rod is slidably installed on the surface of the drying frame, and a limiting block is fixedly installed on the surface of the lifting rod. The fixed plate rotates to contact and press the lifting rod to move upward. The upward movement of the lifting rod drives the limiting block to move upward. The upward movement of the limiting block releases the limiting of the stop block, which can prevent foreign objects from entering the interior of the drying frame when drying is not in progress, thus avoiding affecting the drying effect.

[0012] According to the above technical solution, the fire prevention device includes a gas storage tank, a gas valve, a rotating rod, a limiting plate, and a fuse. When the temperature of the lithium battery inside the drying frame becomes abnormal, the excessively high temperature will burn out the fuse. The burnt fuse will release the limiting plate. The gas storage tank is fixedly installed through the inner and outer walls of the drying frame. The gas valve is fixedly installed on the surface of the gas storage tank. The rotating rod is fixedly installed on the surface of the gas valve. The limiting plate is slidably installed on the surface of the filter plate. The fuse is fixedly installed below the limiting plate. The end of the fuse away from the limiting plate is fixedly installed on the bottom of the inner wall of the drying frame. The limiting plate and the bottom inner wall of the drying frame are fixedly connected by a spring. The gas storage tank stores carbon dioxide. The upward movement of the limiting plate drives the rotating rod to rotate. The rotation of the rotating rod drives the gas valve to rotate. The rotation of the gas valve discharges the carbon dioxide stored in the gas storage tank to cool the inside of the drying frame, preventing fire and reducing safety hazards.

[0013] According to the above technical solution, an exhaust pipe is fixedly installed at the end of the gas valve away from the gas storage tank. A nozzle is fixedly inserted through the surface of the exhaust pipe. Carbon dioxide enters the nozzle through the exhaust pipe and is discharged, which can cool down each lithium battery inside the drying frame, effectively improve the cooling effect, reduce damage to other lithium batteries, and reduce subsequent maintenance costs.

[0014] This invention provides a drying device with a flipping structure. It has the following beneficial effects:

[0015] (1) The drying equipment with the flipping structure starts the motor, and the output end of the motor rotates through the rotating disk to drive the drying frame to rotate. The rotation of the drying frame drives the connecting disk to rotate through the connecting rod and the fixing rod. The rotation of the connecting disk drives the rotating disk to rotate, which realizes the flipping of the lithium battery, so that the upper and lower surfaces of the lithium battery are in more uniform contact with the hot air, improving the drying effect of the lithium battery. At the same time, the rotation of the connecting rod drives the striking rod to strike the filter plate, effectively removing the dust on the surface of the filter plate and avoiding the dust residue on the surface of the filter plate from causing blockage and thus affecting the drying effect.

[0016] (2) The drying equipment with the flip structure moves the lithium battery to contact and squeeze the slider to move. After the slider moves, it resets and drives the clamping plate to clamp and fix the lithium battery. The clamping plate contacts the lithium battery and moves under the pressure, which drives the triangular block to move. After the triangular block moves, it resets and fixes the clamping plate, preventing the lithium battery from falling off the rotating disk during rotation. At the same time, it can prevent the clamping force from being too large and causing damage to the lithium battery. The lithium battery moves to contact and squeeze the clamping plate to move upward. The clamping plate moves upward and drives the resistance block to move and is limited by the fixing plate. It can effectively clamp lithium batteries of different thicknesses and improve the applicability of the drying equipment.

[0017] (3) In this drying equipment with a flipping structure, the fixed plate rotates and contacts the lifting rod to move upward. The upward movement of the lifting rod drives the stop block to rotate through the arc block. The rotation of the stop block drives the rotating shaft and the rotating plate to discharge the air inside the drying frame, improving the air circulation between the inside and outside of the drying frame. This avoids the residual humid air inside the drying frame from affecting the subsequent drying of the lithium battery and improving the drying effect. The fixed plate moves and contacts the lifting rod to move upward. The upward movement of the lifting rod drives the limit block to move upward to release the limit on the stop block. This can prevent foreign objects from entering the drying frame when the drying work is not being carried out, thus avoiding affecting the drying effect.

[0018] (4) When the temperature of the lithium battery inside the drying frame is abnormal, the excessive temperature will burn the fuse, causing it to release the limit plate. After the limit is released, the limit plate moves upward under the action of the spring, driving the rotating rod and the air valve to rotate, and the carbon dioxide stored in the gas tank is discharged to cool the inside of the drying frame, avoiding fire and reducing safety hazards. At the same time, the carbon dioxide cools each lithium battery through the exhaust pipe and nozzle, which can effectively improve the cooling effect, reduce damage to other lithium batteries, and reduce subsequent maintenance costs.

This can effectively clamp lithium batteries of different thicknesses and improve the applicability of the drying equipment.

[0033] In this embodiment, when the motor and dryer are started, the output end of the motor rotates, driving the rotating disk 31 to rotate. The rotation of the rotating disk 31 drives the drying frame 32 to rotate. The rotation of the drying frame 32 drives the connecting disk 34 to move. The movement of the connecting disk 34 drives the connecting rod 35 to move. The movement of the connecting rod 35 drives the gear three on its surface to contact the gear four on the surface of the fixed rod 36 and generate rotation. The rotation of the connecting rod 35 drives the connecting disk 34 to rotate. The rotation of the connecting disk 34 drives the gear on the surface of the rotating disk 33 to rotate together through the gear two. The rotation of the rotating disk 33 realizes the flipping of the lithium battery, making the contact between the top and bottom surfaces of the lithium battery and the hot air more uniform, improving the drying effect of the lithium battery. At the same time, the rotation of the connecting rod 35 drives the striking rod 37 to rotate.

This can effectively clamp lithium batteries of different thicknesses, improving the applicability of the drying equipment.

[0035] Please see Figure 1-8Based on the above embodiments, another embodiment of the present invention further includes a dehumidification device and a fire prevention device. The dehumidification device includes a lifting rod 51, an arc-shaped block 52, a rotating shaft 53, a stop block 54, and a rotating plate 55. The fixed plate 44 rotates to contact and press the lifting rod 51 to move upward. The upward movement of the lifting rod 51 causes the arc-shaped block 52 to move upward. The upward movement of the arc-shaped block 52 contacts and causes the stop block 54 to rotate. The rotation of the stop block 54 causes the rotating shaft 53 to rotate. The lifting rod 51 is slidably mounted on the surface of the drying frame 32. A five-slide groove is provided on the surface of the lifting rod 51. The arc-shaped block 52 is slidably mounted inside the five-slide groove. The rotating shaft 53 rotates. The inner and outer walls of the drying frame 32 are penetrated by a stop block 54, which is fixedly installed on the surface of the rotating shaft 53. The rotating plate 55 is fixedly installed on the surface of the rotating shaft 53. The arc-shaped block 52 is fixedly connected to the inner wall of the slide groove 5 by an elastic telescopic rod 4. The lower part of the lifting rod 51 is opened into an arc surface. A spring spring 3 is provided at the junction of the lifting rod 51 and the drying frame 32. The rotation of the rotating shaft 53 drives the rotating plate 55 to rotate. The rotation of the rotating plate 55 exhausts the air inside the drying frame 32, improves the air circulation between the inside and outside of the drying frame 32, avoids the residual humid air inside the drying frame 32 from affecting the subsequent drying of the lithium battery, and improves the drying effect.

[0036] A lifting rod 56 is slidably installed on the surface of the drying frame 32. A limiting block 57 is fixedly installed on the surface of the lifting rod 56. The fixing plate 44 rotates to contact and press the lifting rod 56 to move upward. The upward movement of the lifting rod 56 drives the limiting block 57 to move upward. The upward movement of the limiting block 57 releases the limiting of the stop block 54, which can prevent foreign objects from entering the interior of the drying frame 32 when drying is not in progress, thus avoiding affecting the drying effect.

[0037] The fire prevention device includes a gas tank 61, a gas valve 62, a rotating rod 63, a limiting plate 64, and a fuse 65. When the temperature of the lithium battery inside the drying frame 32 becomes abnormal, the excessively high temperature will burn out the fuse 65. The burnt fuse 65 will release the limiting plate 64. The gas tank 61 is fixedly installed through the inner and outer walls of the drying frame 32. The gas valve 62 is fixedly installed on the surface of the gas tank 61. The rotating rod 63 is fixedly installed on the surface of the gas valve 62. The limiting plate 64 is slidably installed on the surface of the filter plate 38. The fuse 65 is fixed. Installed below the limiting plate 64, the end of the fuse 65 away from the limiting plate 64 is fixedly installed on the bottom of the inner wall of the drying frame 32. The limiting plate 64 and the bottom inner wall of the drying frame 32 are fixedly connected by a spring. The gas tank 61 stores carbon dioxide. When the limiting plate 64 moves upward, it drives the rotating rod 63 to rotate. The rotation of the rotating rod 63 drives the gas valve 62 to rotate. The rotation of the gas valve 62 discharges the carbon dioxide stored in the gas tank 61 to cool the inside of the drying frame 32, prevent fire, and reduce safety hazards.

[0038] An exhaust pipe 66 is fixedly installed at the end of the air valve 62 away from the air tank 61. A nozzle 67 is fixedly inserted through the surface of the exhaust pipe 66. Carbon dioxide enters the nozzle 67 through the exhaust pipe 66 and is discharged, which can cool down each lithium battery inside the drying frame 32, effectively improve the cooling effect, reduce damage to other lithium batteries, and reduce subsequent maintenance costs.

[0039] In this embodiment, during operation, the fixed plate 44 rotates to contact and press the lifting rod 51 to move upward. The upward movement of the lifting rod 51 causes the arc-shaped block 52 to move upward. The upward movement of the arc-shaped block 52 contacts and causes the stop block 54 to rotate. The rotation of the stop block 54 causes the rotating shaft 53 to rotate. The rotation of the rotating shaft 53 causes the rotating plate 55 to rotate. The rotation of the rotating plate 55 discharges the air inside the drying frame 32, improving the air circulation between the inside and outside of the drying frame 32. This prevents humid air from remaining inside the drying frame 32 and affecting the subsequent drying of the lithium battery, thus improving the drying effect. The fixed plate 44 rotates to contact and press the lifting rod 56 to move upward. The upward movement of the lifting rod 56 causes the limiting block 57 to move upward. The upward movement of the limiting block 57 releases the limiting of the stop block 54, so that the subsequent rotation of the rotating plate 55 is not affected. This prevents foreign objects from entering the drying frame 32 when drying is not in progress, thus avoiding any impact on the drying effect.

[0040] When the temperature of the lithium battery inside the drying frame 32 becomes abnormal, the excessively high temperature will burn out the fuse 65. The blown fuse 65 will release the limit plate 64. After the limit is released, the limit plate 64 moves upward under the action of the spring. The upward movement of the limit plate 64 drives the rotating rod 63 to rotate. The rotation of the rotating rod 63 drives the air valve 62 to rotate. The rotation of the air valve 62 discharges the carbon dioxide stored in the air tank 61 to cool the inside of the drying frame 32, preventing fire and reducing safety hazards. At the same time, the carbon dioxide enters the nozzle 67 through the exhaust pipe 66 and is discharged, which can cool each lithium battery inside the drying frame 32, effectively improving the cooling effect and reducing damage to other lithium batteries, thus reducing subsequent maintenance costs.
