If an abnormal situation such as the tilting of the electronic components of the device i occurs, and there is no abnormality in the immediate advancement, the operation of the load-carrying tool will be shifted to the next station. There is a problem of the action f, so at present, the component of the ^ component = the fixture will be set to _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ If the abnormal situation is reached, it will be sent to the controller to control the machine stop for abnormal elimination. 2. The load-carrying fixture 1 applied on the current machine platform can be a fixed=material loading platform, and a nuclear positioning slot is provided thereon to accurately place the electronic component 2 in the positioning slot i, obliquely placed 'other than the carrying fixture i is fixed i 1 side of the installation - group light: end?", the side of the device is the emission source 31, the other side is ίί sensing the amount of light blocking of the electronic component 2 for the emission source 3 1 Missing: This (4) bears the way of the tool, and has the same as the use of 1342950 1 . Since the light-scattering sensor emits the light beam with the - emitting light source, and receives the light beam with another receiving sensing end 32, the operator When assembling the optical diffuser on the machine table, the installation position and the use height of the transmitting light source 31 and the receiving sensing terminal 32 must be made fresh, resulting in assembly recording; the inconvenience is missing.
2.業者為確實檢查承載治具1之各定位槽11是否承載異常及 電子元件2是否擺置異常，係於機台上相對應各定位槽11 之兩側方均配置有-組由發射歧3 i及接收感測端3 2組 成之光散式感測器，若承載治具1之定位槽1 1數量繁多， 則光散式感測器之配置數量也相對增加，以致相當佔 A 空間，造成不利機台相關裝置配置之缺失。 σ 3·由於各工作站可能依作業需求而分別設置承載治具^ 確實檢查各讀站承載治具1之各定位槽丨丨是 ^ 及電子元件2是否擺置異常，則必須轉工作站之各J載二 ^1财配置相對應定位槽丨m量之光散式感測器，以^ 整個機H設備所需魏之光散絲測雜量相當 組裝耗時，更加耗費成本。 ， 个值 故，如何設計-種可便利設置檢查器 查承載治具之異常狀態，及大幅降: 裝置，即為業者研發之標的。 列2. In the industry, it is necessary to check whether the positioning slots 11 of the bearing fixture 1 are abnormally loaded and whether the electronic component 2 is placed abnormally, and the two sides of the corresponding positioning slots 11 on the machine are arranged with a group-by-emission dislocation. 3 i and the light-scattering sensor composed of the sensing end 32, if the number of the positioning slots 1 1 carrying the jig 1 is large, the number of the arrangement of the optical-dissipating sensors is relatively increased, so that the space is quite occupied. , resulting in the lack of configuration of equipment related to the disadvantaged machine. σ 3·Because each workstation may separately set the bearing fixture according to the operation requirements. ^When the positioning slots of the bearing fixtures 1 of each reading station are checked, and the electronic components 2 are placed abnormally, the workstations must be transferred. The light-scattering sensor with the corresponding amount of slot 丨m is configured to take up the amount of time, which is more time-consuming and costly for the whole machine H equipment. , a value, therefore, how to design - can easily set up the checker to check the abnormal state of the carrying fixture, and drastically: the device, that is, the development of the industry.
