Description

Technical Field

[0001] This invention relates to the field of lithium battery cap technology, and in particular to a lithium battery cap protection process. Background Technology

[0002] A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It differs from rechargeable lithium-ion batteries and lithium-ion polymer batteries. With the development of electronic technology and the increasing miniaturization of devices, higher demands are being placed on power supplies. Lithium batteries have thus entered a stage of large-scale practical application.

[0003] After the lithium battery cap is manufactured, it needs to be treated before being assembled with the lithium battery. The existing processing flow for lithium battery caps includes: degreasing, pickling, drying, polishing, spraying rust inhibitor, testing, and drying. Spraying rust inhibitor on the lithium battery cap is the most important step in the protective treatment process of the lithium battery cap.

[0004] Lithium battery caps are small parts; however, immersing the caps in anti-rust liquid can easily result in uneven application. Spraying the caps with anti-rust liquid can also lead to inconvenient positioning. Therefore, a lithium battery cap protection process is proposed, which solves the above problems by setting up a cap protection device that can conveniently and stably position and clamp the caps and uniformly and stably spray anti-rust liquid. Summary of the Invention

[0005] The purpose of this invention is to provide a lithium battery cap protection treatment process, which solves the problem in the prior art of lacking a lithium battery cap positioning and uniform anti-rust liquid spraying treatment device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A protective treatment process for lithium battery caps utilizes a rust-preventive spraying device. This device includes a frame, a positioning mechanism, a spraying mechanism, and a drying mechanism. The specific process flow for the protective treatment of lithium battery caps is as follows:

[0008] S1. Lithium battery cap positioning: By placing the lithium battery cap on the positioning mechanism inside the frame, the positioning mechanism straightens the lithium battery cap. At the same time, the positioning mechanism drives the lithium battery cap to rotate slowly in a circular motion, and the positioning mechanism conveys the lithium battery cap from the feeding end of the frame to the discharging end of the frame.

[0009] S2. Lithium battery cap spraying: The spraying mechanism sprays both sides of the upper half of the rotating lithium battery cap to ensure that the entire upper half of the lithium battery cap is covered with anti-rust liquid.

[0010] S3. Lithium battery cap drying: The positioning mechanism drives the lithium battery cap to rotate circumferentially at the bottom. After the upper half of the lithium battery is sprayed with anti-rust liquid, it rotates slowly. The drying mechanism dries the sprayed area that rotates down, while the unsprayed part of the lower half rotates to the top. The dried lithium battery cap moves to the positioning mechanism.

[0011] S4. Lithium battery discharge: The coated lithium batteries are conveyed out from the discharge end of the frame through the positioning mechanism;

[0012] The positioning mechanism includes a positioning seat, a drive shaft, and support rollers. Multiple positioning seats are provided, and the multiple positioning seats run in a waist-shaped trajectory. A drive shaft is driven on the positioning seat, and two limiting clamps are symmetrically sleeved on the drive shaft. Two sets of support rollers are symmetrically installed on the positioning seat, and a positioning area is formed between the two sets of support rollers, the two limiting clamps, and the drive shaft.

[0013] The frame is provided with horizontally sliding baffles on both vertical sides, and the side end faces of the two baffles are close to the side end faces of the cap. The positioning mechanism is located inside the frame.

[0014] The spraying mechanism includes a storage tank, a drive pump, and spray nozzles. The drive pump is connected to the storage tank and the spray nozzles respectively. Two sets of spray nozzles are symmetrically arranged, and the two sets of spray nozzles are respectively located above the baffle.

[0015] The drying mechanism includes a blower and a suction fan. The blower is connected to a blower head, and two sets of blower heads are symmetrically arranged and located below the baffle. The suction fan is connected to a suction pipe, and the suction pipe is located below the positioning seat.

[0016] Preferably, the side end face of the frame is provided with a limiting groove, the baffle is Z-shaped, the side end face of the baffle is provided with a limiting strip that slides in cooperation with the limiting groove, and the side end face of the frame is provided with multiple positioning rods, with the baffle placed above the positioning rods.

[0017] Preferably, the top horizontal end of the baffle is located on the horizontal diameter line of the cap, and the bottom horizontal end of the baffle is located below the horizontal diameter line of the cap.

[0018] Preferably, two drive rollers are mounted on the frame via a transmission belt, with the transmission belt positioned at both ends of the drive rollers. Two shafts are provided on both sides of the bottom of the positioning seat, and the positioning seat is mounted to the shafts. The two ends of the shafts are respectively mounted to the transmission belts on both sides. A support seat is installed inside the frame, and the support seat is in contact with the lower part of the shaft.

[0019] Preferably, the two ends of the support roller are movably connected to the positioning seat through bearing seats, and the middle part of the drive shaft is provided with multiple silicone strips in a circular array. The line connecting the center of the two support rollers and the center of the drive shaft forms a V-shaped structure.

[0020] Preferably, a screw is installed on the positioning seat, and two sets of threaded structures are symmetrically arranged on the screw. A motor for driving the positioning seat to rotate is installed on the positioning seat. The limiting clamp is slidably connected to the drive shaft, and the bottom end of the limiting clamp is installed with the screw through a nut sleeve.

[0021] Preferably, the positioning seat has a sliding groove, the bottom end of the limiting clamp is limited to slide within the sliding groove, and a motor for controlling the rotation of the drive shaft is installed on the positioning seat.

[0022] Preferably, the blower head is oriented near the lower part of the baffle, and the suction pipe is located between the positioning seat and the shaft.

[0023] This invention has at least the following beneficial effects:

[0024] 1. Driven by a positioning mechanism, the cap rotates circumferentially, causing the uncoated area to rotate above the baffle and the coated area to rotate below the baffle to receive drying. The cap receives coating and drying evenly, and the baffle receives excess coating material, ensuring internal cleanliness. This process achieves a lithium battery cap protection treatment with uniform rust-preventive liquid spraying.

[0025] 2. The baffle has a Z-shaped structure, which lowers the bottom horizontal end of the baffle so that the center of the cap is above the baffle. This further supplements the spraying of the center of the cap and reduces the occurrence of uneven spraying of the rust inhibitor. The baffle can be directly pulled out of the frame for easier cleaning.

[0026] 3. By setting up a positioning mechanism consisting of a positioning seat, a drive shaft, a support roller, a shaft rod, a limit clamp, and a screw, a protective treatment device with stable and convenient positioning is realized, which can accurately spray anti-rust liquid onto small cap parts.

[0034] Example 1

[0035] Reference Figure 1-4 A protective treatment process for lithium battery caps utilizes a rust-preventive spraying device, which includes a frame 3, a positioning mechanism 4, a spraying mechanism 6, and a drying mechanism 5. The specific process flow for the protective treatment of lithium battery caps is as follows:

[0036] S1. Positioning of lithium battery cap: By placing the lithium battery cap on the positioning mechanism 4 inside the frame 3, the positioning mechanism 4 straightens the lithium battery cap. At the same time, the positioning mechanism 4 drives the lithium battery cap to rotate slowly in a circular motion. The positioning mechanism 4 conveys the lithium battery cap from the feeding end of the frame 3 to the discharging end of the frame 3.

[0037] S2. Lithium battery cap spraying: Spraying mechanism 6 sprays both sides of the upper half of the rotating lithium battery cap to ensure that the entire upper half of the lithium battery cap is coated with anti-rust liquid.

[0038] S3. Drying of lithium battery cap: The positioning mechanism 4 drives the lithium battery cap to rotate in a circular motion at the bottom. After the upper half of the lithium battery is sprayed with anti-rust liquid, it rotates slowly. The drying mechanism 5 dries the sprayed part that rotates down, while the unsprayed part of the lower half rotates to the top. The dried lithium battery cap moves to the positioning mechanism 4.

[0039] S4. Lithium battery discharge: The coated lithium battery is conveyed out from the discharge end of the frame 3 via the positioning mechanism 4;

[0040] The positioning mechanism 4 includes a positioning seat 401, a drive shaft 402, and a support roller 406. Multiple positioning seats 401 are provided, and the multiple positioning seats 401 move in a waist-shaped trajectory. The drive shaft 402 is driven on the positioning seat 401. Two limiting clamps 403 are symmetrically sleeved on the drive shaft 402. Two sets of support rollers 406 are symmetrically installed on the positioning seat 401. A positioning area is formed between the two sets of support rollers 406, the two limiting clamps 403, and the drive shaft 402.

[0041] Baffles 7 are horizontally slidably installed on both vertical sides of the frame 3. The side end faces of the two baffles 7 are close to the side end faces of the cap. The positioning mechanism 4 is installed inside the frame 3.

[0042] The spraying mechanism 6 includes a storage tank 601, a drive pump 602 and a spray head 603. The drive pump 602 is connected to the storage tank 601 and the spray head 603 respectively. Two sets of spray heads 603 are symmetrically arranged, and the two sets of spray heads 603 are respectively arranged above the baffle 7.

[0043] The drying mechanism 5 includes a blower 501 and a suction fan 503. The blower 501 is connected to a blower head 502. Two sets of blower heads 502 are symmetrically arranged and are located below the baffle 7. The suction fan 503 is connected to a suction pipe 504, which is located below the positioning seat 401.

[0044] In this embodiment: by placing the cap on the drive shaft 402 of the positioning mechanism 4, with the two sides of the cap limited by two support rollers 406, during the process of the multiple positioning mechanisms 4 in a waist-shaped transmission, the spray nozzle 603 of the spraying mechanism 6 sprays the two sides above the cap baffle 7, while the blower head 502 of the drying mechanism 5 sprays the two sides below the baffle 7. After the cap is dried, the area of ​​the cap rotates circumferentially under the rotation of the drive shaft 402 of the positioning mechanism 4, so that the unsprayed area rotates to the top of the baffle 7, and the sprayed area rotates to the bottom of the baffle 7 to receive drying, thereby achieving the effect of uniform drying of the lithium battery cap. The baffle 7 can not only receive excess spray liquid, but also be pulled out for convenient cleaning, improving the convenience of the cap spraying protection treatment device.

[0045] In one embodiment: a limiting groove 9 is provided on the side end face of the frame 3, the baffle 7 has a Z-shaped structure, a limiting strip 10 that slides in cooperation with the limiting groove 9 is installed on the side end face of the baffle 7, a plurality of positioning rods 8 are installed on the side end face of the frame 3, and the baffle 7 is placed above the positioning rods 8; the top horizontal end of the baffle 7 is located on the horizontal diameter line of the cap, and the bottom horizontal end of the baffle 7 is located below the horizontal diameter line of the cap; the blower head 502 faces the position close to the lower part of the baffle 7, and the suction pipe 504 is located between the positioning seat 401 and the shaft 405;

[0046] In this embodiment, the baffle 7 has a Z-shaped structure, which lowers the bottom horizontal end of the baffle 7 so that the center position of the cap is above the baffle 7, thereby further supplementing the spraying of the center position of the cap and further reducing the occurrence of uneven spraying of the cap rust inhibitor; and the baffle 7 can be directly pulled out of the frame 3, making cleaning more convenient.

[0047] In one embodiment: two drive rollers 1 are mounted on the frame 3 via a transmission belt 2, with the transmission belt 2 positioned at both ends of the drive rollers 1. Two shafts 405 are provided on both sides of the bottom of the positioning seat 401, and the positioning seat 401 is mounted to the shafts 405. The two ends of the shafts 405 are respectively mounted to the transmission belts 2 on both sides. A support seat 11 is installed inside the frame 3, and the support seat 11 is in contact with the lower part of the shafts 405. The two ends of the support roller 406 are movably connected to the positioning seat 401 via bearing seats. Multiple silicone strips are arranged in a circular array in the middle of the drive shaft 402. The center of the two support rollers 406 and the center of the drive shaft 402 form a V-shaped structure; a screw 404 is installed on the positioning seat 401, and two sets of threaded structures are symmetrically arranged on the screw 404; a motor for driving the positioning seat 401 to rotate is installed on the positioning seat 401; a limiting clamp 403 is slidably connected to the drive shaft 402, and the bottom end of the limiting clamp 403 is installed with the screw 404 through a nut sleeve; a sliding groove is opened on the positioning seat 401, and the bottom end of the limiting clamp 403 is limited to slide within the sliding groove; a motor for controlling the rotation of the drive shaft 402 is installed on the positioning seat 401.

[0048] In this embodiment: the motor controls the drive shaft 402 to rotate, so that the cap rotates. The limiting clamps 403 on both sides move relative to each other under the rotation of the screw 404 to straighten the cap. The two support rollers 406 improve the stability of the cap. The setting of the two shafts 405 at the bottom of the positioning seat 401 improves the stability of the positioning seat 401. The setting of the support seat 11 improves the stability of the multiple positioning mechanisms 4 of the horizontal transmission. Thus, a protective treatment device with stable and convenient positioning and precise anti-rust spraying of small parts of the cap is realized.
