Description

Technical Field

[0001] This utility model relates to the technical field of transverse pulling equipment for diaphragm production, and in particular to a transverse pulling chain lubrication mechanism. Background Technology

[0002] The lithium-ion battery separator is a key component of lithium-ion batteries, and its performance has a significant impact on the battery's safety, charge-discharge efficiency, and cycle life. In lithium-ion battery separator production, the transverse stretching equipment preheats the porous separator, after the extractant has been removed, to its softening point temperature using physical methods. This is followed by expansion and pore enlargement, and then transverse shrinkage to eliminate internal stress. Finally, it is cooled and shaped to improve the separator's longitudinal and transverse tensile strength and pore size.

[0003] In the cross-stretching equipment used in lithium battery separator production, the lubrication of the cross-stretching chain and its bearings is crucial. Existing technologies mostly employ a timed and metered injection of lubricating oil using an oiling machine. This method can precisely control the amount of lubricating oil while ensuring the continuous and stable operation of the chain and bearings under high-temperature and high-load conditions.

[0004] The shortcomings of the existing technical solutions are as follows: In the horizontal stretching equipment for lithium battery separator production, the dry film process requires high-speed operation to ensure production efficiency. However, when using a traditional oiling machine to inject lubricating oil in a timed and quantitative manner, the centrifugal force generated by the high-speed operation of the equipment easily causes oil droplets to be thrown out and adhere to the separator surface, forming oil spot contamination. These oil spots not only affect the appearance quality of the separator but may also lead to a decrease in electrochemical performance, causing product defects and increasing the scrap rate. Utility Model Content

[0005] This utility model provides a lubrication mechanism for a horizontal chain, which can solve the problem in the prior art where oil droplets are easily thrown out and adhere to the diaphragm surface when using a traditional oil injection machine to inject lubricating oil in a timed and quantitative manner.

[0006] A horizontal chain lubrication mechanism includes an oil cup bracket with an interface on which an oil cup is detachably mounted. A connecting support plate is fitted on one side of the oil cup bracket for detachable connection with a device track plate. The horizontal chain on the device track plate is located below the oil cup bracket, and the movement path of multiple bearings on the horizontal chain is located below the oil cup bracket. A guide hole is provided in the middle of the oil cup bracket, which guides the lubricating oil output from the oil cup to the lower end of the oil cup bracket. When the bearings pass through the lower end of the oil cup bracket, they carry away the oil droplets that are about to form, completing a splash-free oiling operation.

[0007] As a further aspect of this utility model: there is a gap of 0.5~1.5mm between the lower end height of the oil cup bracket and the upper end height of the bearing.

[0008] As a further embodiment of this utility model, the connecting support plate is fixedly disposed between the oil cup bracket and the connecting support plate.

[0009] As a further embodiment of this utility model, a height adjustment component is provided between the connecting support plate and the oil cup bracket.

[0010] As a further embodiment of this utility model: the height adjustment component includes a fixed frame fixedly mounted on the oil cup bracket, the connecting support plate being longitudinally slidably fitted within the fixed frame, and a threaded rod being rotatably mounted on the fixed frame, the threaded rod being threadedly fitted with the connecting support plate.

[0011] As a further embodiment of this utility model, the oil cup support is equipped with an optical detection mechanism for detecting whether the installation height of the oil cup support is qualified.

[0012] As a further embodiment of this utility model: the optical detection mechanism includes a hanging plate detachably mounted on the oil cup bracket, and a laser emitter is provided at the lower end of the hanging plate, the laser emitter emitting a laser beam located below the guide hole laterally.

[0013] As a further embodiment of this utility model: a limiting groove is provided on the oil cup bracket, and a docking block that cooperates with the limiting groove is fixedly provided on the hanging plate.

[0014] As a further embodiment of this utility model: a limiting rod is fixedly provided in the limiting groove, and a limiting hole that cooperates with the limiting rod is provided on the docking block.

[0015] As a further embodiment of this utility model: a guide rod that slides and engages with the connecting support plate is longitudinally fixed inside the fixed frame.

[0016] The beneficial effects of this utility model are: 1. This utility model sets the height of the oil cup support so that its lower end has a gap of 0.5-1.5mm between it and the upper end of the bearing. When the bearing passes the lower end of the oil cup support, it carries away any oil droplets that are about to form, applying a layer of lubricating oil to the bearing surface, thus achieving splash-free oil injection. This method avoids the formation of airborne oil droplets, uses less lubricating oil, and due to surface tension, the oil is less likely to be thrown out, effectively reducing the possibility of diaphragm contamination.

[0017] 2. This utility model is equipped with a fixed frame, a threaded rod, and a guide rod. Rotating the threaded rod can drive the connecting support plate to move longitudinally, adjusting the height of the oil cup bracket. The guide rod ensures stable movement and can adapt to different scenarios. On the other hand, it is equipped with a photoelectric detection mechanism that uses a laser emitter to emit a laser beam. Adjusting the height of the oil cup bracket ensures that the laser beam falls on the upper end of the bearing without being blocked, achieving precise positioning, ensuring reasonable spacing, and high installation and adjustment accuracy.

[0020] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0021] like Figures 1 to 6 As shown in the figure, this utility model provides a horizontal chain lubrication mechanism, including an oil cup bracket 2. The oil cup bracket 2 has an interface 202 on which an oil cup 1 is detachably mounted. The oil cup 1 stores lubricating oil to provide an oil source for the entire lubrication process. A connecting support plate 201 is fixedly mounted on one side of the oil cup bracket 2. This connecting support plate 201 is used for detachable connection with the equipment track plate, thereby securely mounting the entire lubrication mechanism on the equipment. Figure 1As shown, the horizontal chain 3 on the equipment track plate is located below the oil cup bracket 2. The moving path of the multiple sets of bearings 301 on the horizontal chain 3 is also located below the oil cup bracket 2, allowing the oil cup bracket 2 to apply lubricating oil to the bearings 301 along their movement path. A guide hole 208 is provided in the middle of the oil cup bracket 2, which guides the lubricating oil output from the oil cup 1 to the lower end of the oil cup bracket 2. During actual installation and use, the height of the oil cup bracket 2 needs to be adjusted so that there is a gap of 0.5~1.5mm between the lower end of the oil cup bracket 2 and the upper end of the bearing 301. After practice and optimization, a 1mm gap is preferred. When the bearing 301 passes the lower end of the oil cup bracket 2, it carries away the oil droplets that are about to form, thus applying a layer of lubricating oil to the surface of the bearing 301 at the lower end of the oil cup bracket 2, thereby completing the splash-free oiling operation. This operating method does not form oil droplets floating in the air. At the same time, due to the small amount of lubricating oil and the influence of surface tension, the oil on the surface of bearing 301 will not be splashed out, thereby reducing the possibility of diaphragm contamination.

[0022] However, in practical applications, the operating environment of the oil cup bracket 2 is complex and involves many uncertainties, making it difficult to install the oil cup bracket 2 at the appropriate height. This can lead to an inability to precisely control the distance between the lower end of the oil cup bracket 2 and the upper end of the bearing 301. Improper control of this distance will affect the lubrication effect and may even cause new problems.

[0023] To address the issue of precise height control, the mechanism is further optimized in the second embodiment. A fixed frame 203 is fixedly mounted on the oil cup bracket 2. A connecting support plate 201 slides longitudinally within the fixed frame 203. A threaded rod 204 is rotatably mounted on the fixed frame 203, threadedly engaging with the connecting support plate 201. By rotating the threaded rod 204, the connecting support plate 201 moves longitudinally, thereby adjusting the height of the oil cup bracket 2 and ensuring the mechanism can adapt to different application scenarios. To ensure the stability of the oil cup bracket 2 during movement, a guide rod 205 is longitudinally fixed inside the fixed frame 203, slidingly engaging with the connecting support plate 201. The guide rod 205 serves to guide and stabilize, preventing the oil cup bracket 2 from swaying or shifting during height adjustment.

[0024] When installing the oil cup holder 2, it is still difficult to precisely adjust the distance between the oil cup holder 2 and the bearing 301. However, this distance must be within the range of 1.5mm or less; otherwise, the oil droplets output by the oil cup holder 2 may be too large, resulting in an excessive amount of oil applied in a single application. The oil droplets will be more easily thrown out, thus affecting the lubrication effect and equipment operation.

[0025] To further address the issue of precise spacing adjustment, an optical inspection mechanism 4 is installed on the oil cup bracket 2 to check whether its installation height is within acceptable limits. The optical inspection mechanism 4 includes a detachable hanging plate 403 mounted on the oil cup bracket 2. A laser emitter 404 is located at the lower end of the hanging plate 403. The laser emitter 404 emits a laser beam laterally below the guide hole 208, positioned 1 mm below the guide hole 208. During installation of the oil cup bracket 2, by adjusting its height, the laser beam falls on the upper end of the bearing 301, ensuring that the beam passes over the upper surface of the bearing 301 without being blocked. This completes the positioning of the oil cup bracket 2, ensuring that the distance between the oil cup bracket 2 and the bearing 301 is within a reasonable range.

[0026] Furthermore, to facilitate the assembly of the optical testing mechanism 4 and ensure its accurate installation, a limiting groove 206 is provided on the oil cup bracket 2, and a mating block 401 that mates with the limiting groove 206 is fixedly installed on the hanging plate 403. A limiting rod 207 is fixedly installed in the limiting groove 206, and a limiting hole 402 that mates with the limiting rod 207 is provided on the mating block 401. When assembling the hanging plate 403, the mating block 401 is first inserted into the limiting groove 206, so that the limiting rod 207 is inserted into the limiting hole 402. The horizontal height of the mating block 401 is determined by the position of the limiting rod 207, ensuring that the optical testing mechanism 4 can be accurately installed.

[0027] Working Principle: First, the oil cup 1 containing lubricating oil is detachably installed on the oil cup bracket 2 via interface 202, providing an oil source for the subsequent lubrication process. Next, the hanging plate 403 of the optical inspection mechanism 4 is assembled, and the mating block 401 on the hanging plate 403 is inserted into the limiting groove 206 on the oil cup bracket 2, so that the limiting rod 207 in the limiting groove 206 is inserted into the limiting hole 402 on the mating block 401, and the horizontal height of the mating block 401 is determined by the limiting rod 207. At this time, the laser emitter 404 in the optical inspection mechanism 4 emits a laser beam laterally located below the guide hole 208 and 1 mm below the guide hole 208. Finally, the entire lubrication mechanism is detachably connected to the equipment track plate via the connecting support plate 201, completing the initial installation.

[0028] By rotating the threaded rod 204, the connecting support plate 201 is moved longitudinally, thereby adjusting the height of the oil cup bracket 2. During the height adjustment, precise positioning is achieved using the laser emitted by the optical inspection mechanism 4. The height of the oil cup bracket 2 is adjusted so that the laser beam falls on the upper end of the bearing 301 on the horizontal chain 3, ensuring that the beam passes over the upper surface of the bearing 301 without obstruction. This completes the positioning of the oil cup bracket 2, ensuring that the distance between the lower end of the oil cup bracket 2 and the upper end of the bearing 301 is within a reasonable range of 0.5-1.5mm. After installation, the optical inspection mechanism 4 can be removed.

[0029] When the equipment is running, as the bearing 301 on the horizontal chain 3 moves along the path to below the oil cup support 2, the lubricating oil in the oil cup 1 is guided to the lower end of the oil cup support 2 through the guide hole 208 in the middle of the oil cup support 2. Because there is a suitable gap between the lower end of the oil cup support 2 and the upper end of the bearing 301, when the bearing 301 passes the lower end of the oil cup support 2, it carries away any oil droplets that are about to form, thus coating the surface of the bearing 301 at the lower end of the oil cup support 2 with a layer of lubricating oil, completing the splash-free oiling operation. This operation method does not form oil droplets floating in the air, and because the amount of lubricating oil is small and affected by surface tension, the oil on the surface of the bearing 301 will not be splashed out, reducing the possibility of diaphragm contamination.

[0030] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
