  • Patent number: 10751985
    Abstract: The present invention teaches a device for lifting a flexible substrate from its glass substrate, including a supply reel, a take-up reel, a lifting roller, and an adhesive tape. The supply reel spins to deliver the adhesive tape. The adhesive tape has a first side and a second side opposite to each other. The lifting roller contacts the second side of the adhesive tape. The lifting roller moves along a lateral direction parallel to the glass substrate and presses the flexible substrate so that the flexible substrate is adhered to the first side of the adhesive tape. The take-up reel spin to retract the adhesive tape and the flexible substrate adhered to the first side of the adhesive tape is lifted from the glass substrate. The lifting device achieves effective and gentle separation of the flexible substrate and the glass substrate through the traction of adhesive tape.

  • Publication number: 20190186807
    Abstract: A detachable quick-freezing food storage case is provided that includes a storage case body and a quick-freezing fan assembly. The quick-freezing fan assembly comprises a quick-freezing fan support and a quick-freezing fan. The quick-freezing fan support includes an air inlet positioned proximate the quick-freezing fan. The storage case body includes a return air inlet. The quick-freezing fan support surrounds one of the air outlets on a cold air duct board to form an air circulation path from the air outlet, through the air inlet, to the return air inlet. The storage case body also includes a cover fitting the storage case body. The quick-freezing fan is connected to a main control panel, and the main control panel is connected to a display control panel. The storage case is also detachable, making it convenient for customers to use refrigerator space efficiently.
