Technical Field

[0001] The utility model relates to the technical field of telephone assembly, in particular to a single-machine double-cylinder independent pressing device for front shell lenses. Background Art

[0002] At present, many of the existing telephone products use adhesive bonding technology to install the lenses (display screens) on the products. According to the previous traditional process, if there are two lenses on one surface that need to be pressed together, two pressing blocks are usually installed on a cylinder, and then the cylinder moves to achieve the purpose of pressing. This method has certain disadvantages. Since the two lenses may not be on the same plane and have a certain height difference, the pressing blocks of the jig are also made with a certain height difference according to the drawings. Due to the influence of product tolerances and the accuracy of jig processing, there is a certain error between the height difference of the actual pressing block and the height difference of the product lens, which will cause one of the lenses to be pressed loosely. It is now urgently needed to produce a single-machine dual-cylinder independent pressing jig to avoid the loose pressing phenomenon caused by the height difference between the two lenses.

[0003] Therefore, we have developed a single-machine dual-cylinder independent pressing device for the front shell lens to solve the above problems. Utility Model Content
