Description

Technical Field

[0001] The utility model relates to the technical field of optical adhesive production, and specifically to an OCA optical adhesive sub-packaging and anti-sticking blanking device. Background Art

[0002] The OCA optical adhesive packaging and anti-sticking blanking device is a precision equipment used in the optical industry, mainly used for OCA packaging and anti-sticking treatment.

[0003] OCA optical adhesive has extremely high transparency, so it is often used in various electronic screens. For this reason, OCA optical adhesive needs to be packaged into cans. In order to prevent the OCA optical adhesive from sticking together before packaging and becoming difficult to transport, it will be stirred as much as possible in a flowing liquid state. The OCA optical adhesive is then squeezed into the delivery tube through the liquid, and then delivered to the hose through the glue injection head.

[0004] However, in actual use, the delivery of optical glue is intermittent. When the optical glue stops after moving forward for a certain distance, the glue injection head will also stop and inject the next glue tube. This will cause colloid to remain on the end face and inside of the glue injection head. When the colloid is diluted too much or the stop time is too long, the colloid will drip, resulting in colloid waste and pollution of the working environment. For this reason, we propose an OCA optical glue packaging and anti-sticking discharging device. Utility Model Content

[0005] A technical problem to be solved by this application is: how to design an OCA optical glue dispensing and anti-sticking feeding device that can prevent the glue inside the glue injection head from dripping.

[0008] A pneumatic component is provided on the bottom plate and is used for scraping the residual OCA optical glue inside the glue injection head with the arc scraper. The hydraulic glue storage box squeezes the OCA optical glue inside by hydraulic pressure, and the pneumatic component can be driven by the gas inside the hydraulic glue storage box to collect the scraped OCA optical glue;

[0009] The linkage component is arranged on the synchronous positioning device and is used for synchronously driving the arc scraper away from and close to the inside of the glue injection head when the synchronous positioning device lowers and raises the glue injection head.

[0010] In some embodiments, the linkage assembly includes an L-shaped plate arranged at the bottom of the synchronous positioning device, a rack is arranged on the side of the L-shaped plate, a fixed frame is arranged on the top of the base plate, a fixed plate is arranged on the side of the fixed frame, a gear is movably arranged on the side of the fixed plate, and the tooth surface of the gear is movably arranged on the tooth surface of the rack.

Then, the driving member can drive the arc scraper to scrape off the residual colloid in the injection head, thereby avoiding contamination of the working ring.

Obviously, the described embodiment is only a part of the embodiment of this utility, not all of the embodiments. Based on the embodiment of this utility, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this utility.

[0030] The arc scraper 8 is movably arranged on the inner wall of the bottom end of the glue injection head 7, and a plurality of arc scrapers 8 are provided. The arc scraper 8 has a scraping function and can also throw out the scraped colloid in the direction of rotation;

[0031] The pneumatic assembly 5 is arranged on the bottom plate 1 and is used for scraping the residual OCA optical adhesive inside the adhesive injection head 7 by the arc-shaped scraper 8. The hydraulic adhesive storage box 2 squeezes the OCA optical adhesive inside by hydraulic pressure, and the pneumatic assembly 5 is driven by the gas inside the hydraulic adhesive storage box 2 to collect the scraped OCA optical adhesive;

[0032] The linkage assembly 6 is arranged on the synchronous positioning device 3 and is used to synchronously drive the arc scraper 8 away from and close to the inside of the glue injection head 7 when the synchronous positioning device 3 lowers and raises the glue injection head 7.

[0033] The linkage assembly 6 includes an L-shaped plate 61 arranged at the bottom of the synchronous positioning device 3, a rack 62 is arranged on the side of the L-shaped plate 61, a fixing frame 4 is arranged on the top of the bottom plate 1, a fixing plate 64 is arranged on the side of the fixing frame 4, and a gear 63 is movably arranged on the side of the fixing plate 64. The tooth surface of the gear 63 is movably arranged on the tooth surface of the rack 62. When the rack 62 is raised or lowered, it can drive the gear 63 to rotate.

[0034] A rotating rod 65 is movably provided inside the fixed plate 64, and one end of the rotating rod 65 is movably provided on the end face of the gear 63. A connecting rod 66 is provided on the end of the rotating rod 65 away from the gear 63. The rotating rod 65 can drive the connecting rod 66 to rotate, and the connecting rod 66 can drive the pneumatic component 5 to rotate.

[0035] The pneumatic assembly 5 includes a rotating tube 53 arranged on the end face of the connecting rod 66. The interior of the rotating tube 53 is movably arranged on the outer surface of the glue injection head 7. A glue storage tank 52 is provided at the bottom of the rotating tube 53. A connecting tube 51 is provided inside the glue storage tank 52. One end of the connecting tube 51 is provided on the top inner wall of the hydraulic glue storage box 2. A driving member 9 for driving the arc scraper 8 to rotate is provided at the bottom of the rotating tube 53. The hydraulic gas of the hydraulic glue storage box 2 is sucked into the glue storage tank 52 through the connecting tube 51, and the glue storage tank 52 collects the colloid scraped from the inside through the rotating tube 53.

[0036] The driving member 9 includes a shaft 93 arranged on the side of the arc scraper 8. The bottom end of the shaft 93 passes through the inner wall of the rotating tube 53 and is provided with a micro motor 91. Two side plates 92 are provided on the side of the micro motor 91. The tops of the two side plates 92 are both provided at the bottom of the rotating tube 53. The provided micro motor 91 has a driving effect, and can therefore drive multiple arc scrapers 8 to rotate.

[0037] When using this device, the hydraulic glue storage box 2 will descend and drive the L-shaped plate 61 to descend, while driving the glue injection head 7 to inject the glue tube. After completion, it will rise, which can drive the L-shaped plate 61 to rise. The L-shaped plate 61 drives the rack 62 set on the side to move, and the rack 62 drives the gear 63 set on the outer surface to rotate.

For this purpose, the arc scraper 8 can be driven to enter the interior of the glue injection head 7. The micro motor 91 is started to drive the arc scraper 8 set on the outer surface of the shaft 93 to rotate, so that the residual colloid inside the glue injection head 7 can be scraped off and dropped into the interior of the rotating tube 53.

[0038] When the driving hydraulic pressure drives the colloid inside the hydraulic glue storage box 2 to move, it can drive the gas inside the connecting pipe 51 to be sucked in, and the connecting pipe 51 sucks the inside of the glue storage tank 52. The internal gas and colloid are sucked out through the glue storage tank 52 using the rotating tube 53 and sucked out into the interior of the glue storage tank 52, completing the collection effect.

The torsion spring 10 has a reset function, and moves inside the arc groove 12 through the slider 11, which has a certain self-protection to avoid contact between them and the injection head 7, resulting in breakage.
