Detailed Description
As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, an apparatus that is configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). A communication terminal arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. A cellular phone is an electronic device equipped with a cellular communication module.
The inventor researches for a long time to find that the existing glue spraying equipment has single function, can only carry out corresponding glue spraying operation on the middle frame of the display screen assembly generally, and then needs to be transferred to other equipment to carry out corresponding subsequent operation so as to finish the processing of the display screen assembly. But because the data between the equipment are independent each other and not intercommunicated, consequently can't adjust the processing parameter of display screen subassembly through the mode that the data was compared to obtain more accurate processing parameter, reduced the gluey yields of spouting of display screen subassembly to a certain extent. In the years of popularization of comprehensive screens of mobile phones, the viscose surfaces of middle frames of the mobile phones are increasingly narrow, the middle frames are designed more and more complexly, influence caused by errors of machining parameters is undoubtedly huge, and glue spraying equipment with a single function cannot meet machining requirements of current display screen assemblies of the mobile phones. Meanwhile, the existing glue spraying equipment generally adopts a light source polishing mode to assist a 2D camera to scan a mobile phone middle frame so as to obtain contour data. However, the error of the profile data acquired by the 2D camera is relatively high, and because the light source needs to perform corresponding light-emitting scheme design on mobile phone middle frames of different styles, the universality is poor, and the method cannot adapt to the design of mobile phone middle frames of various styles.
In order to solve the above problem, an embodiment of the present application provides a processing device for a multifunctional display screen assembly. The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.
