Locating device for flexible sheet

Abstract

The invention provides a locating device for a flexible sheet and belongs to the technical field of machining equipment. By means of the locating device, the problem that over-suction arises when an existing flexible sheet is sucked is solved. The locating device for the flexible sheet comprises a rack. A material frame is arranged on the rack. A material-taking arm is connected to the portion, ona side portion of the material frame, of the rack in a swinging manner. The material-taking arm is fixedly connected with a material-taking frame. Two material-taking blocks are slidingly connected with the material-taking frame. Both the two material-taking blocks are provided with material-taking surfaces. Each material-taking surface is provided with a plurality of material-taking suction holes. Locating blocks are also slidingly connected with the material-taking frame. Each locating block is provided with a locating surface, and locating suction holes are formed in each locating surface.The material-taking frame is also provided with driving parts by which the two material-taking blocks can be driven to approach and move relatively. A transmission structure is arranged between the material-taking blocks and the locating blocks, wherein when the two locating blocks approach and move relatively, the locating blocks are driven to move upwards by the transmission structure. According to the locating device for the flexible sheet, automatic feeding of the flexible sheet can be achieved; and the phenomenon that multiple flexible sheets are sucked simultaneously can be avoided.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment and relates to a flexible sheet positioning device. Background technique [0002] Flexible sheets, such as mobile phone diaphragms, are relatively common auxiliary tools for mobile phones. When the mobile phone leaves the factory, a mobile phone diaphragm will be pasted on the screen to protect the mobile phone screen. The mobile phone diaphragm is roughly rectangular and has There is a certain degree of elasticity, and there are corresponding through holes at the position of the diaphragm and the button of the mobile phone. During the processing of the diaphragm, the raw material of the diaphragm needs to be cut into a rectangular diaphragm first, and the cut diaphragms are usually stacked together, and then The holes are taken one by one, and due to the electrostatic adsorption phenomenon between the diaphragms, it is easy to adhere to the redundant diaphragm when taking ...

[0002] Flexible sheets, such as mobile phone diaphragms, are relatively common auxiliary tools for mobile phones. When the mobile phone leaves the factory, a mobile phone diaphragm will be pasted on the screen to protect the mobile phone screen. The mobile phone diaphragm is roughly rectangular and has There is a certain degree of elasticity, and there are corresponding through holes at the position of the diaphragm and the button of the mobile phone. During the processing of the diaphragm, the raw material of the diaphragm needs to be cut into a rectangular diaphragm first, and the cut diaphragms are usually stacked together, and then The holes are taken one by one, and due to the electrostatic adsorption phenomenon between the diaphragms, it is easy to adhere to the redundant diaphragm when taking out the diaphragm, and because the diaphragm is soft, the positioning accuracy is poor, resulting in the quality of the hole reduced, which also leads to lower overall processing efficiency
