Description

Technical Field

[0001] This utility model relates to the field of infrared glue application technology, specifically to an infrared-guided precision glue application device. Background Technology

[0002] Precision adhesive application is a key process in industrial production. It refers to the uniform and accurate application of adhesive to designated areas of an item to be processed, following a preset path and thickness requirement, to achieve functions such as bonding, sealing, and fixing. In electronic equipment assembly, precision adhesive application ensures stable connections between components and prevents circuit performance from being affected by adhesive layer issues. In the automotive manufacturing industry, it ensures good sealing of body component joints, improving the vehicle's waterproof, dustproof, and sound insulation effects. In furniture production, precision adhesive application makes the joints of boards aesthetically pleasing and strong. As various industries continue to increase their requirements for product precision, quality, and lifespan, precision adhesive application has become an important link in ensuring product performance and reducing subsequent maintenance costs, and is an indispensable process in modern industrial production. Traditional glue application operations often rely on operators manually controlling the glue application tools based on their experience, or on simple mechanical glue application equipment. These traditional techniques often lack effective positioning guidance mechanisms. During the glue application process, operators are easily affected by factors such as visual fatigue and differences in operational proficiency, making it difficult to accurately control the glue application path and glue layer thickness. Simple mechanical glue application equipment cannot flexibly adapt to items of different sizes and heights, leading to problems such as glue application position deviation and uneven glue layer. These defects not only cause a large amount of adhesive waste and increase production costs, but also result in quality risks such as weak adhesion and poor sealing performance of products. In severe cases, it can even lead to product scrapping, affecting production efficiency and the company's market competitiveness. To address this, we propose an infrared-guided precision glue application device. Utility Model Content

[0023] Working Principle: First, the basic assembly and fixation of the device are carried out. Four threaded cylinders are pre-installed at the top front of the glue-applying base 1. The bottom end of the glue-applying fixing seat 2 corresponds to these threaded cylinders and is securely connected to the glue-applying base 1 using bolts, providing a stable platform for the items to be glued. The items to be glued are then placed inside the glue-applying fixing seat 2. Simultaneously, two positioning cylinders are also provided at the top of the glue-applying base 1. A fixing groove 11 is opened on the inner side of the fixing strip 3. After placing the positioning cylinders inside the fixing groove 11, the fixing strip 3 is also installed to the glue-applying base 1 using bolts. The fixing strip 3 is located behind the glue-applying fixing seat 2. Next, the height adjustment structure is built and adjusted. An adjustment support rod 4 is fixedly installed on the top left side of the fixing strip 3 for adjustment. The cylindrical surface of the support rod 4 has vertically distributed adjusting grooves 12, and multiple equidistant adjusting limiting holes 13 are also provided on both sides of the adjusting grooves 12. The left cylindrical surface of the movable adjusting cylinder 5 has a first telescopic hole 15. The top of the adjusting support rod 4 passes through the first telescopic hole 15 and forms a sliding fit, allowing the movable adjusting cylinder 5 to move up and down along the adjusting support rod 4. To fix the movable adjusting cylinder 5 at a specific height, a limiting movable cavity 16 communicating with the first telescopic hole 15 is provided inside the left side of the movable adjusting cylinder 5. The end of the limiting adjusting rod 6 of the limiting adjusting mechanism is provided with a guide plate, and multiple limiting springs 7 are provided on the back of the guide plate. Adjusting limiting ends 14 are provided on both sides of the front end of the guide plate, and the adjusting limiting ends 14 are located on the limiting adjusting rod. On both sides, the guide plate at the end of the limiting adjustment rod 6 and the limiting spring 7 are placed inside the limiting movable cavity 16. The front end of the limiting adjustment rod 6 passes through the left end of the movable adjustment cylinder 5 and slides within the adjusting groove 12. When the movable adjustment cylinder 5 is adjusted to a suitable height, the adjusting limiting end 14 will correspondingly engage with the adjusting limiting hole 13, thus fixing the height of the movable adjustment cylinder 5 on the adjusting support rod 4. If the height needs to be adjusted again, simply press the front end of the limiting adjustment rod 6 to compress the limiting spring 7, causing the adjusting limiting end 14 to disengage from the adjusting limiting hole 13. Then, the movable adjustment cylinder 5 can slide along the adjusting groove 12. After adjustment, release the limiting adjustment rod 6. Under the elastic force of the limiting spring 7, the adjusting limiting end 14 will again engage with the corresponding adjusting limiting hole 13 to complete the fixation. First, the horizontal infrared positioning structure is installed and its position adjusted. A second telescopic hole 17, perpendicular to the limiting cavity 16, is provided inside the right side of the movable adjusting cylinder 5. An internal threaded hole 18 is also provided at its right end. A locking bolt 10 is threaded into the internal threaded hole 18. The end of the infrared positioning rod 8 passes through the second telescopic hole 17 and penetrates the right side of the movable adjusting cylinder 5. Since the infrared positioning rod 8 and the adjusting support rod 4 are perpendicularly distributed, and the adjusting support rod 4 is located on the left side of the movable adjusting cylinder 5, the infrared positioning rod 8 can be pulled laterally along the second telescopic hole 17 to adjust its length extending out of the movable adjusting cylinder 5. After adjusting to the appropriate position, the locking bolt 10 is tightened so that its end is tangentially engaged with the cylindrical surface of the infrared positioning rod 8, fixing the infrared positioning rod 8 through friction.To prevent lateral displacement during subsequent operations and achieve precise glue application guided by infrared light, an infrared guide head 9 is installed at the front end of the infrared positioning rod 8. After adjusting the lateral position of the infrared positioning rod 8 and the height of the moving adjustment cylinder 5, the bottom end of the infrared guide head 9 is precisely positioned above the center of the glue application fixture 2. At this point, activating the infrared guide head 9 causes it to emit infrared light downwards, precisely projecting it onto the surface of the item to be glued, placed inside the glue application fixture 2, forming a clear positioning mark. Operators or automated glue application equipment can accurately determine the glue application position based on this infrared positioning mark and perform the glue application along the marked path, thus achieving precise glue application and effectively ensuring the accuracy and consistency of glue application, avoiding glue application quality problems caused by positioning deviations.
