Description

Technical Field

[0001] This utility model relates to the field of storage battery technology, specifically to a double scraper mechanism for a casting and welding machine. Background Technology

[0002] Lead-acid batteries consist of positive plates, negative plates, fiberglass separators, and plastic shells. After being assembled by a pre-slotting machine, they are welded together by a casting and welding machine with a casting and welding mold. The casting and welding mold needs to be lifted from the molten lead, and then the excess molten lead on the surface of the casting and welding mold is scraped off by a scraper to ensure the consistency of the busbar thickness and weight, thereby improving the welding quality.

[0003] In the existing process of scraping molten lead with a scraper, the automated production line uses a single scraper to scrape the molten lead back and forth. When the scraper scrapes back and forth, it comes into contact with the molten lead on the casting mold, resulting in molten lead adhering to the scraper. When the scraper retracts and scrapes the casting mold, the molten lead on the scraper flows onto the surface of the casting mold, causing the molten lead to not be completely scraped off. This results in inconsistent molten lead removal with each back and forth scraping, making it difficult to guarantee the thickness of the manifold and reducing the quality of the weld.

[0004] For example, patent application number 202321519578.9 discloses a variable reversible automatic scraper assembly. This utility model relates to the field of battery technology, specifically to a variable reversible automatic scraper assembly, including a lead-water tank and a support plate disposed on the lead-water tank, with a lifting mechanism provided on the lead-water tank. In summary, this variable reversible automatic scraper assembly employs the mutual adjustment of two scraper bodies. During reciprocating motion, the two scraper bodies scrape the surface of the casting mold separately, improving the scraping capacity and ensuring that the amount of lead scraped off each time is consistent, thus guaranteeing the thickness of the manifold in the casting mold and improving the welding quality. However, when processing different types of batteries, this variable reversible automatic scraper assembly requires changing to different types of casting molds. The existing dual-scraper structure cannot adjust the spacing between the scrapers according to the battery type, affecting the lead scraping effect.

[0005] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed a double scraper mechanism for casting and welding machines. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-2 As shown, a double scraper mechanism for a casting and welding machine includes a placement frame 1. A guide groove 2 102 is provided in the middle of the upper surface of the placement frame 1, and a placement block 2 is provided on the left side of the guide groove 2 102. A servo motor 201 is mounted on the surface of the placement block 2, and a bidirectional spiral drive rod 202 is provided at the output end of the servo motor 201. This technical solution, through the setting of the bidirectional spiral drive rod 202, can dynamically optimize the scraping accuracy, compensate for mold wear, adapt to process fluctuations such as lead viscosity when using the double scraper body 301 to scrape away lead liquid, ensure uniform scraping force, avoid lead residue, and guarantee casting and welding quality. At the same time, the spacing of the scraper body 301 can be adjusted according to the different models and sizes of the batteries being produced.

[0023] Furthermore, a sliding sleeve 203 is spirally installed on the outer surface of the bidirectional spiral drive rod 202, and the sliding sleeve 203 and the guide groove 102 are configured to slide. This technical solution, through the setting of the sliding sleeve 203, can restrict the sliding direction of the pneumatic push rod 204, and prevent the pneumatic push rod 204 from tilting during displacement, thus affecting the scraping effect of the scraper body 301.

[0024] Furthermore, a pneumatic push rod 204 is provided on the inner surface of the sliding sleeve 203, and a push plate 205 is provided at the output end of the pneumatic push rod 204. Limiting slide rods 22 and 32 are slidably installed on the lower surfaces of both sides of the push plate 205, and scraper body 301 is provided on the lower surface of the limiting slide rod 22 and 32. With this technical solution, the lead water on the mold can be scraped off multiple times by setting the front and rear scraper bodies 301, thereby improving the scraping efficiency of lead water.

[0025] Furthermore, the upper surface of the push plate 205 is provided with limiting slide rods 206 on both sides, and the outer surface of the limiting slide rods 206 is provided with guide sliders 207. The upper surface of the placement frame 1 is provided with guide grooves 101 on both sides, and the guide grooves 101 and the guide sliders 207 are slidably connected. With this technical solution, the limiting slide rods 206 can be driven to slide synchronously during the displacement of the pneumatic push rod 204 by the setting of the guide sliders 207.

[0026] like Figures 3-4 As shown, a limit plate 302 is provided on the lower surface of the limit slide bar 2 3, and a return spring 304 is installed on the outer surface of the limit slide bar 2 3. With this technical solution, by setting the return spring 304, when the scraper body 301 contacts the mold, the elastic return characteristic of the return spring 304 can drive the scraper body 301 to always stick to the mold surface, maintain the uniformity of scraping force, and when the scraper body 301 encounters the mold surface with too much undulation, the elastic contraction of the return spring 304 can drive the scraper body 301 to rebound and protect the scraper body 301.

[0027] Furthermore, the upper outer surface of the limiting slide bar 3 is provided with a threaded groove 303, and a spiral sleeve 305 is spirally installed on the outer surface of the threaded groove 303. The spiral sleeve 305 and the upper surface of the return spring 304 are configured for frictional connection. In this technical solution, by setting the spiral sleeve 305, the return spring 304 can be pressed down by rotating along the threaded groove 303, thereby adjusting the rebound threshold of the return spring 304 to ensure that the scraper body 301 always fits against the surface of the mold.

[0028] Working Principle: When using the double scraper mechanism of this casting and welding machine, firstly, after the battery busbar production is completed, the system will automatically adjust the parameters of the double scraper mechanism according to the battery model: First, the servo motor 201 is started to drive the bidirectional spiral transmission rod 202 to rotate, which drives the sliding sleeve 203 to slide synchronously along the guide slide groove 102, accurately completing the spacing adjustment of the two scraper bodies 301. When the linear motor smoothly lifts the mold from the lead water tank, the pneumatic push rod 204 synchronously drives the push plate 205 to descend, and at the same time, the limiting slide rod 206 limits the push plate 205, so that the scraper body 301 quickly reaches the working position.

[0029] During the mold pulling process, the front scraper body 301 first contacts the mold surface. The return spring 304 ensures that the scraper and mold surface are in constant contact through an elastic adaptive mechanism, completing the dynamic calibration of the scraping force within 0.1 seconds. The rear scraper body 301 follows closely behind, performing a secondary scraping of the residual lead, forming a collaborative operation mode of "coarse scraping + fine scraping". During this process, the distance and pressure between the two scrapers are matched with the mold parameters in real time, ensuring that the residual lead in different types of manifolds is controlled below 0.3g / cycle, improving scraping efficiency by 40%. This is the working principle of the dual scraper mechanism used in this casting and welding machine.
