Description

Technical Field

[0001] The utility model relates to the technical field of cleaning, in particular to an automatic cleaning device for residual glue at a glue coating port. Background Art

[0002] In the glue application work with a relatively small amount of glue, the sealant is usually applied to the surface of the part through a glue application tube. Because the sealant has surface tension, a small amount of sealant will always protrude from the glue application port after each application. This poses two problems:

[0003] 1. The surface area of ​​the sealant exposed to the air is larger, which is easily contaminated by dust and affects the quality of the sealant, affects the coating of subsequent parts, and easily causes airtight leakage, high parts failure rate and rework rate;

[0004] 2. When the amount of glue applied is very small, the protruding sealant will easily lead to a significant increase in the amount of glue applied, and the amount of sealant used is difficult to control.

[0005] In the past, people mostly relied on manual cleaning of residual glue on the glue application port with a rag. However, there may be risks of forgetting or not cleaning in time, and the above hidden dangers cannot be guaranteed to be eliminated, resulting in unqualified parts.

[0006] Therefore be necessary to improve the glue coating structure to solve the above problems. Utility Model Content

[0009] Specifically, the scraper blade is a rectangular thin sheet perpendicular to the length direction of the swing arm, and the scraper blade is elastic.

[0010] Specifically, a limit block is further provided in the middle of the bracket, and the limit block is located above the rotating shaft of the swing arm and limits the maximum swing angle of the swing arm.

[0011] Furthermore, the residual glue cleaning mechanism also includes a fixed plate, the swing arm, the limit block and the telescopic cylinder are arranged on the front side of the fixed plate, and the back side of the fixed plate is connected to the bracket.

[0012] Furthermore, the limit block is a right-angled trapezoidal structure, the long bottom side of the limit block is fixed on the bracket, the right-angled waist of the limit block faces downward, and the side of the limit block is provided with a hollow hole.

[0013] Furthermore, a buffer block is provided on the right-angle waist of the limit block, and the buffer block serves as a contact component between the limit block and the swing arm.

[0014] The beneficial effects of the technical solution of the utility model are:

[0024] The utility model is further described in detail below in conjunction with specific embodiments.

[0025] Example:

[0026] like Figure 1 and Figure 2As shown, the utility model is an automatic cleaning device for residual glue at the glue coating port, comprising a bracket 1 and a glue coating tube 2 arranged on the upper part of the bracket 1 with the glue coating port 21 facing downward, a residual glue cleaning mechanism 3 is also provided in the middle part of the bracket 1, and the residual glue cleaning mechanism 3 comprises a swing arm 31 arranged on one side of the bracket 1 and rotating around a horizontal axis, a telescopic cylinder 32 driving the swing arm 31 to rotate in a vertical plane, a glue scraping cylinder 33 arranged at the free end of the swing arm 31 and a glue scraping plate 34 driven by the glue scraping cylinder 33 to move forward and backward along the length direction of the swing arm 31, when the swing arm 31 is in a horizontal position, the glue scraping plate 34 is close to the glue coating tube 2 and the highest edge of the glue scraping plate 34 is flush with the glue coating port 21.

[0027] The telescopic cylinder 32 is used to control the swing arm 31 to swing, thereby determining whether the scraper blade 34 is close to or away from the glue coating port 21. When the scraper blade 34 is close to the glue coating port 21, the scraper cylinder 33 drives the scraper blade 34 to translate, thereby scraping the edge of the glue coating port 21, so that the residual glue protruding from the glue coating port 21 can be removed. The device can realize automatic scraping of the residual glue at the glue coating port 21 through the air path control of the telescopic cylinder 32 and the scraper cylinder 33, ensuring the timely cleaning of the glue coating port 21, saving labor, and effectively improving the smoothness of the sealant coating and the qualified rate of the airtightness test results.

[0028] like Figure 3 As shown, the scraper blade 34 is a rectangular thin sheet perpendicular to the length direction of the swing arm 31, and the scraper blade 34 is elastic.

[0029] The scraper blade 34 needs to move along the edge of the glue coating opening 21 to scrape more cleanly, but the telescopic cylinder 32 may not be very accurate in controlling the angle of the swing arm 31, so the telescopic cylinder 32 can make the swing angle of the swing arm 31 slightly higher, so that the scraper blade 34 can scrape the glue coating opening 21 in a deformed state.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, a limit block 35 is further provided in the middle of the bracket 1 . The limit block 35 is located above the rotation axis of the swing arm 31 and limits the maximum swing angle of the swing arm 31 .

[0031] There is a relatively strict positional relationship between the scraper blade 34 and the glue application port 21. If they are too close, the glue application tube 2 may be easily knocked crooked, and if they are too far away, the scraper blade 34 cannot scrape the residual glue. However, because the scraper cylinder 33 and the scraper blade 34 are located at the end of the swing arm 31, a small angle error will lead to a large distance error. Therefore, it is necessary to limit the swing angle of the swing arm 31 through a limit block 35, so that after the swing arm 31 swings up, the scraper blade 34 stops at an appropriate position.

[0032] like Figure 1 , Figure 2 and Figure 4As shown, the residual glue cleaning mechanism 3 also includes a fixing plate 37 , a swing arm 31 , a limit block 35 and a telescopic cylinder 32 are arranged on the front side of the fixing plate 37 , and the back side of the fixing plate 37 is connected to the bracket 1 .

[0033] The other parts of the residual glue cleaning mechanism 3 are fixed on the fixing plate 37. The relative position correction between the parts can be completed before being installed on the bracket 1, and the fixing is also more convenient.

[0034] like Figure 4 As shown, the limit block 35 is a right-angled trapezoidal structure, the long bottom side of the limit block 35 is fixed on the bracket, the right-angle waist of the limit block is downward, and a hollow hole 351 is provided on the side of the limit block 35.

[0035] This type of limit block 35 has a smaller structure and is more capable of withstanding the impact of the swing arm 31 .

[0036] like Figure 4 As shown, a buffer block 36 is provided on the right-angle waist of the limit block 35 , and the buffer block 36 serves as a contact component between the limit block 35 and the swing arm 31 .

[0037] The buffer block 36 can prevent the limit block 35 from hard collision with the swing arm 31, reduce noise, and prevent parts from being damaged. If the buffer block 36 is worn out too much, it can be replaced to ensure the position accuracy of the highest swing angle of the swing arm 31.

[0038] The working process of the automatic cleaning device for residual glue at the glue coating port is as follows:

[0039] When applying glue, the swing arm 31 swings down so that the glued parts can reach the bottom of the glue application tube 2; after the gluing is completed, the glued parts are moved away, and the telescopic cylinder 32 drives the swing arm 31 to swing up until it is blocked by the buffer block 36. At this time, the scraper 34 approaches the glue application port 21, and then the scraper cylinder 33 drives the scraper 34 to scrape across the edge of the glue application port 21 to remove the residual glue.

[0040] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
