Description

Technical Field

[0001] The invention relates to the technical field of upper cover tape processing, in particular to a uniform glue coating device for heat-sealed upper cover tape processing. Background Art

[0002] The cover tape is a material widely used in the packaging and protection of electronic and electrical components. It is usually made of plastic, metal or composite materials and has good sealing, flexibility and heat resistance. It is mainly used to cover the surface of electrical components or the position of components in the tray. Through physical protection and sealing, it prevents the components from being polluted and physically damaged by the external environment, while ensuring its stability during transportation, storage and use. Heat-sealing the cover tape is a key process to firmly adhere the cover tape to the components or their substrates. Compared with other bonding methods, heat sealing can form a uniform and firm bonding layer between the cover tape and the substrate through heating and pressure. Gluing is an important link in the heat-sealing cover tape process, which directly determines the bonding effect and sealing performance of the cover tape. By evenly applying glue on the glue layer of the cover tape, it forms a firm bonding layer with the substrate during heat sealing to avoid falling off or displacement due to poor bonding.

[0003] The glue coating devices currently on the market are usually equipped with a glue delivery pump, which transmits the glue to the nozzle or brushing device through a pipeline to ensure that the glue is distributed on the glue coating layer of the upper cover belt, and the glue coating layer is processed with a scraper to ensure the thickness consistency of the glue coating layer.

[0004] The scraper is usually a fixed scraper plate. Since the scraper is fixed in a rigid position, it is difficult to flexibly adjust it according to the glue thickness of the upper cover belt coating or the width of the upper cover plate, resulting in uneven thickness of the glue layer, which in turn affects the heat sealing quality and sealing performance.

The air collecting duct 9011 provides a continuous air source for the heating box 901. By connecting the fan 9012, a stable air input is achieved. The fan 9012 provides a strong airflow for the heating box 901, ensuring smooth air flow and sufficient heating.

[0048] See also Figure 12-13 A guide assembly is provided on the outer side of the tooth plate 907. The guide assembly is used to guide the movement of the tooth plate 907, providing a stable track for the movement of the tooth plate 907 to prevent deviation or shaking during operation. A guide plate 909 is fixedly connected to the outer side of the tooth plate 907. A guide groove 9010 is provided on the outer side of the mounting frame 10. The guide plate 909 is slidably connected to the guide groove 9010. The guide plate 909 is slidably connected to the guide groove 9010. By limiting the movement direction of the tooth plate 907, it is ensured that the meshing of the tooth plate 907 and the gear 906 is always accurate, so that the angle adjustment of the storage tube 904 is more accurate and reliable.

[0049] Working principle: The upper cover belt on the unwinding roller 2 is pulled out, and passes through the inside of the cleaning box 401, the bottom of the glue outlet pipe 507, the bottom of the scraper plate 605, between the two scraper plates 704, the bottom of the air supply head 905, and is connected with the components of the subsequent process.

[0050] The fixing plate 402 inside the cleaning box 401 provides downward pressure through the tightening spring 403, so that the multiple brushes 405 contact the rubber layer of the upper cover belt, and the brushes 405 clean the dust and impurities on the rubber layer of the material. The elastic force of the spring ensures that the brushes 405 maintain appropriate contact strength with the material and will not damage the rubber layer of the upper cover belt. At the same time, the exhaust fan 406 is started, and the exhaust fan 406 generates negative pressure, and the dust cleaned by the brushes 405 is sucked into the cleaning box 401 through the output pipe 407. The dust is intercepted by the filter plate 4011 of the filter box 409, and the clean air is discharged through the outlet pipe 4010, thereby keeping the working environment clean.

[0051] By starting the delivery pump 502, the delivery pump 502 draws glue from the glue storage box 501 and transmits it to the discharge pipe 504 through the feed pipe 503. The diverter pipe 505 distributes the glue output by the delivery pump 502 to multiple soft discharge branch pipes 506. The flexibility of these soft discharge branch pipes 506 makes the glue discharge range adjustable to avoid affecting the glue coating effect due to the rigidity of the pipeline. The soft discharge branch pipe 506 transports the glue to the glue discharge pipe 507. The glue discharge pipe 507 is controlled by the cylinder 508 to move up and down. The cylinder 508 adjusts the distance between the glue coating pipe and the upper cover belt through the telescopic end to ensure uniform glue coating and comprehensive coverage.

[0052] The scraper plate 605 is fixed by the connecting rod 602 and contacts the glue layer of the upper cover plate. The torsion spring 604 provides adjustable pressure so that the scraper plate 605 can adapt to different glue thicknesses and scrape off excess glue to ensure consistent glue thickness. The two ends of the connecting rod 603 are rotatably connected to the inner side of the limit frame 11. The angle of the scraper plate 605 is adjusted according to the width of the cover plate and the glue thickness to ensure uniform glue coating.

[0053] By starting the motor 701, the motor 701 drives the bidirectional threaded rod 702 to rotate. Through the bidirectional design of the bidirectional threaded rod 702, the movable plate 703 is moved along the axial direction of the bidirectional threaded rod 702, thereby driving the scraper plate 704 to move, and then the scraper plate 704 is attached to the edge of the upper cover belt. When applying glue, when the upper cover belt passes through the scraper plate 704, excess glue is scraped off to ensure the width of the glue and the neatness of the edge, and to avoid excess glue from contaminating other parts.

[0054] The glue coating mechanism 5 evenly coats the glue on the glue coating layer of the upper cover belt through the glue outlet pipe 507. Some excess glue cannot adhere due to the error in the coating amount or the overflow of the edge of the material. The excess glue is scraped off the glue coating layer of the upper cover belt by the scraper plate 605 and the scraper plate 704. The glue naturally falls into the collection frame 801 due to gravity. The rotating plate 806 is rotated to unlock the rotating plate 806 and the locking plate 805. Then, the handle 802 is pulled to pull the mounting plate 803 out of the mounting shell 804, and then the glue in the collection frame 801 is collected. The recycled glue can be processed and then enter the glue storage box 501 again, so as to be recycled, thereby reducing glue waste, improving the utilization rate of raw materials, and reducing production costs.

[0055] After the heating wire 902 inside the heating box 901 is energized, it is quickly heated to generate hot air. After the fan 9012 is energized and heated, the heated air is sent to the heat supply pipe 903. The heat supply pipe 903 sends the heated air to the storage tube 904. Then the storage tube 904 is connected to multiple air supply heads 905 to blow out hot air evenly. It is started by the electric telescopic rod 908. The electric telescopic rod 908 drives the tooth plate 907 to move, so that the outer guide plate 909 of the tooth plate 907 moves along the guide groove 9010. The tooth plate 907 is meshed with the gear 906, and the angle and position of the storage tube 904 are adjusted to make the hot air cover the processing area, and the upper cover belt glue layer is slightly blown, so that the upper cover belt glue layer has a uniform and stable glue layer, and the process will not be difficult due to the glue being too wet.
