Description
Technical Field
[0001] The utility model relates to the technical field of glass processing, in particular to a fixed rack used for processing tempered glass films of mobile phones. Background Art
[0002] Glass has become popular in people's lives. Glass products can be seen everywhere, such as the glasses we drink water from, glass windows, glass doors, screen protectors on computer monitors, glass buildings, tempered glass films for mobile phones, etc.
[0003] During the production and processing of tempered glass film for mobile phones, the glass sheet to be processed needs to be cut into the required tempered film shape by a cutting machine, and then polished and ground by CNC processing, and finally tempered at high temperature to make the tempered glass film required for the tempered film; since the glass film material is thin and fragile, a turnover rack is needed to place the glass film material in order to ensure that the glass film material can be transported, tempered, cleaned or stored during the production and processing. The traditional turnover rack is generally configured as a closed-loop side frame, and a plurality of fixed racks are arranged on the side frame to form a space for placing the glass film material between two adjacent fixed racks. A plurality of grooves are arranged on the fixed racks, so that multiple pieces of glass film material can be inserted in an arranged manner between two adjacent fixed racks through the grooves, and a toothed structure matching the grooves is provided at the bottom of the side frame, so that the glass film material can be supported by at least three points, thereby ensuring that it can be stably placed in the turnover rack.
[0004] Existing fixed racks, such as the Chinese authorized utility model patent with announcement number CN214869925U, have been found in actual applications that when the glass film material is inserted into the groove position of the fixed rack (i.e., the outer tooth groove in the CN214869925U patent), it can only be inserted along the notch direction of the groove position of the fixed rack, that is, it can only be inserted vertically. However, when the glass film material is inserted manually or by a robot, an angle deviation is inevitable, which causes the insertion of the glass film material to be easily stuck, affecting the processing efficiency, and easily causing the corners of the lower end of the glass film material to collide with the corners of the notch of the groove position of the fixed rack, resulting in damage.
[0005] Therefore, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content
