Description

Technical Field

[0001] The utility model relates to the technical field of solder ball production, in particular to a solder ball mold cleaning device. Background Art

[0002] The main uses of solder balls are widely used in tinplate, flux, organic synthesis, chemical production, alloy manufacturing, and the assembly of multiple integrated circuits in the electronics industry. They are also used as reagents and reducing agents for the determination of arsenic and phosphates, and tin-plated products. The production of solder balls is inseparable from molds.

[0003] The mold needs to be cleaned after production is completed. However, the solder balls are small and the gaps in the mold are also small. It is difficult to clean effectively without special tools. Therefore, operators disassemble the mold for cleaning. Disassembling the mold affects the production of solder balls. Frequent disassembly of the mold can easily cause the mold to be loosely combined.

[0004] In view of this, we propose a solder ball mold cleaning device that can enter the narrow mold inner wall and clean it quickly. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 - Figure 5 , the utility model provides a technical solution:

[0026] A solder ball mold cleaning device includes a cleaning component 1 and two groups of extension brackets 2. The cleaning component 1 includes a roller 11 and a fixed block 12. Two rollers 11 are provided. The fixed blocks 12 are fixed on both sides of the roller 11. The fixed blocks 12 of the two rollers 11 are connected by a telescopic rod 13. The two groups of cleaning components 1 are provided with extension brackets 2 on both sides. The surfaces of the extension brackets 2 are provided with scrapers 3. The front ends of the fixed blocks 12 are provided with guide brackets 4. The rollers 11 connected by two telescopic rods 13 allow the rollers 11 of the cleaning component 1 to enter the interior of the mold at any spacing, and the extension brackets 2 on both sides can be contracted synchronously. At the same time, the telescopic rod 13 allows the rollers 11 to always fit the inner wall surface of the mold. This allows the cleaning device to quickly clean the narrow inner wall of the mold.

[0027] There are two groups of guide brackets 4, which are respectively installed on the surfaces of the fixed blocks 12 on both sides of the roller 11. The guide brackets 4 include two folding rods 41, which are connected by a coupling 42. The two folding rods 41 form an angle of 15°-60° through the coupling 42, so that a triangular structure is formed between the folding rods 41 and the fixed blocks 12, so that the guide frame can be smoothly inserted into the mold, thereby guiding the cleaning component 1 at the rear end to enter the mold.

[0028] The scraper 3 includes a top scraper 31 and a scraper strip 32. The top scraper 31 is installed at the upper end of the expansion frame 21, and the scraper strip 32 is installed at the bottom end of the extension bracket 2. Through the two scrapers 3, after the cleaning component 1 completes cleaning, the scraper 3 wipes off the cleaning liquid remaining on the surface of the mold, thereby improving the cleaning efficiency.

[0029] The top scraper 31 includes a bottom plate 311 and a supporting bracket 314, wherein the bottom plate 311 is mounted on the top of the supporting bracket 314, and an angle of 20°-70° is maintained between the supporting bracket 314 and the bottom plate 311. A rubber strip 312 is detachably connected to the surface of the bottom plate 311, and a water collecting tank 313 is arranged on one side of the rubber strip 312. Since the bottom plate 311 is tilted and fixed on the surface of the supporting bracket 314, the cleaning liquid scraped off by the rubber strip 312 flows into the water collecting tank 313 at the bottom under the action of gravity, thereby preventing the cleaning liquid scraped off from the top from falling into the mold at the bottom to cause secondary pollution, thereby ensuring effective cleaning. Through the detachable rubber strip 312, after the rubber strip 312 of the top scraper 31 is worn, there is no need to disassemble the assembly, and the rubber strip 312 can be replaced, thereby reducing the cost of equipment use.

[0030] The extension bracket 2 includes two outward expansion frames 21, and a telescopic column 22 is arranged between the outward expansion frames 21. A handle 23 is fixed to the surface of the telescopic column 22. The outward expansion frame 21 of the extension bracket 2 and the roller 11 can float up and down synchronously through the telescopic column 22, and the handle 23 is installed at the bottom end of the telescopic column 22, so that the up and down floating of the outward expansion frame 21 does not affect the holding of the handle 23.

[0031] The surface of the folding rod 41 is evenly distributed with multiple rollers, so that the resistance of the folding rod 41 when contacting the mold is reduced, so that the guide bracket 4 has less running resistance when entering the mold, and at the same time reduces the wear of the guide bracket 4 on the mold.

[0032] When the solder ball mold cleaning device of the utility model is in use, after the upper mold and the lower mold of the solder ball mold are separated, the cleaning device can be used to quickly clean them, and the cleaning liquid is applied to the surfaces of the two rollers 11 of the cleaning component 1, and then the operator holds the handles 23 on the extended brackets 2 on both sides of the cleaning component 1 with both hands, and then aligns the guide bracket 4 at the front end of the cleaning component 1 with the upper and lower gaps of the mold, and removes the cleaning device, and the upper and lower folding rods 41 of the guide bracket 4 contact the mold. During the forward movement of the inclined folding rods 41, the two folding rods 41 are squeezed by the upper and lower molds, so that the folding rods 41 are folded inwardly through the coupling 42. Since the ends of the folding rods 41 are fixedly connected to the surfaces of the fixed blocks 12, the telescopic rods 13 between the fixed blocks 12 are driven to be compressed, and the rollers 11 installed on the fixed blocks 12 synchronously compress the spacing. After the guide bracket 4 completely enters the interior of the mold, the rollers 11 after the spacing is compressed are more likely to enter the gap inside the mold, and the rollers 11 enter the interior of the mold after being squeezed by the upper and lower molds, and then Continue to push the cleaning component 1 to move on the inner wall of the mold, so that the roller 11 is attached to the inner wall surface of the mold under the action of the telescopic rod 13, and the roller 11 continues to roll the cleaning brush on the surface of the inner wall of the mold. While the roller 11 applies the cleaning liquid, the rear end top scraper 31 and the scraper strip 32 scrape the cleaning liquid off, wherein the top scraper 31 is composed of a bottom plate 311, a rubber strip 312, a water collection tank 313 and a supporting bracket 314. The rubber strip 312 on the bottom plate 311 removes the cleaning liquid on the mold through the supporting bracket 314. After scraping, the cleaning liquid slides down the bottom plate 311 under the action of gravity and enters the sump 313 of the bottom plate 311, preventing the cleaning liquid of the upper mold from falling onto the surface of the lower mold and causing secondary pollution. At the same time, the scraper 32 also discharges the cleaning liquid to the outside of the mold to prevent cleaning residues from remaining inside the mold. Therefore, the operator only needs to grasp the handle 23 of the extended bracket 2 and move the cleaning device once inside the mold to quickly clean the inner wall surface, thereby improving the efficiency of daily mold cleaning and reducing daily mold cleaning.
