Description

For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0036] In one embodiment of the present application, as shown in Figures 1-12 An automatic light-shielding adhesive equipment is provided, which comprises a feeding device 10, a carrying manipulator 20, a positioning device 30, an attaching device 40, a film pressure maintaining device 50, a film tearing device 60, a pressing device 70 and a discharging device 80. The film pressure maintaining device 50, the film tearing device 60 and the pressing device 70 are sequentially arranged and located on the moving stroke of the carrying manipulator 20.

[0037] The feeding device 10 is arranged at the starting end of the whole equipment, and is used for feeding products. The height of the position of the feeding device 10 is matched with the grabbing height of the carrying manipulator 20, so that the carrying manipulator 20 can smoothly grab the products.

[0038] The carrying manipulator 20 is used for carrying the products of the feeding device 10 to the next station. The carrying manipulator 20 is located above the feeding device 10, the positioning device 30, the attaching device 40, the film pressure maintaining device 50, the film tearing device 60 and the pressing device 70. The movement track of the carrying manipulator 20 covers the stations of the devices, and the carrying manipulator 20 can flexibly move between the stations to realize the carrying of the products.

[0039] The positioning device 30 receives the products carried by the carrying manipulator 20 and is used for positioning the positions of the products. The positioning device 30 is adjacent to the feeding device 10 and is located on the moving path of the carrying manipulator 20, so as to conveniently receive the products carried by the carrying manipulator 20.

[0040] The attaching device 40 comprises a taking mechanism 41 for the light-shielding glue, an attaching mechanism 42 for attaching the light-shielding glue to the product, and a vision mechanism 43 for rectifying the deviation of the product and the light-shielding glue. The taking mechanism 41, the attaching mechanism 42 and the vision mechanism 43 are integrated on the workbench of the attaching device 40, and the vision mechanism 43 is arranged above and below the product and the light-shielding glue to detect the position deviation in all directions. The taking mechanism 41 and the attaching mechanism 42 perform the picking and attaching operations of the light-shielding glue on the workbench according to the detection result of the vision mechanism 43.

[0041] The film pressure maintaining device 50 is used for rolling the product after the glue is attached. The film tearing device 60 is used for tearing the blue film on the product after rolling. The pressing device 70 is used for pressing the product to avoid the light-shielding glue from being taken out and shaping the edge of the product. The discharging device 80 is arranged on the side of the pressing device 70 opposite to the film tearing device 60 and is used for picking the product processed by the pressing device 70. The film pressure maintaining device 50, the film tearing device 60 and the pressing device 70 are arranged in sequence along the moving direction of the conveying manipulator 20 to form continuous processing stations. The rolling part of the film pressure maintaining device 50 is in a horizontal position to facilitate the rolling of the product. The film tearing mechanism of the film tearing device 60 is arranged behind the rolling station to timely tear the blue film of the product after rolling. The pressing device 70 is arranged at the last station, and the pressing plate thereof faces the product to ensure that the product can be effectively shaped.

[0042] The double positioning and rectifying by the positioning device 30 and the vision mechanism 43 effectively solves the problem of low attaching precision in the traditional glue attaching method, reduces the deviation, bubbles, wrinkles and other defects, and improves the optical performance and yield of the product. The automatic feeding, conveying, attaching and subsequent processing process greatly improves the production efficiency, can meet the demand of mass production, reduces the labor cost and production cycle. The attaching device 40 can adjust the parameters according to the shape and size of the product, and combined with the detection of the vision mechanism 43, can adapt to the glue attaching demand of different shapes (such as irregular shape and curve), and widen the application range of the equipment. The orderly cooperation of the film pressure maintaining device 50, the film tearing device 60 and the pressing device 70 ensures that the product after glue attaching is fully processed, avoids the falling and displacement of the light-shielding glue, improves the stability and reliability of the product quality, and reduces the rework and scrap rate of the product.

The third feeding optical fiber 14 is located at the output end of the second conveying line 15. The tail block 16 is arranged at the output end of the second conveying line 15. Specifically, when the first feeding optical fiber 11 detects the product feed, the stepping motor of the first conveying line 12 starts to drive, stops when the product flows to the position of the second feeding optical fiber 13, and buffers the product. After the product is taken away by the carrying manipulator 20, the third feeding optical fiber 14 feeds back the no-feed signal, the stepping motor of the second conveying line 15 is driven, the product flows to the discharge position, and is limited by the tail block 16. The third feeding optical fiber 14 feeds back the feed signal, and the belt module alignment mechanism 17 is driven to position the product, which can meet the consistency of the feeding and discharging positions of products of different sizes.
