Title: Mechanism for orientating electrical components
IPC: H01J9/38
Filed: 1959-04-15
Abstract: 878,306. Making hermetically sealed electric components. SYLVANIA ELECTRIC PRODUCTS Inc. April 15, 1959 [April 21, 1958], No. 12874/59. Class 39(2). A mechanism for orientating cylindrical electric components such as valves having spaced electric contact leads projecting therefrom in which it is desired to pass a current through the filament during the process of manufacture, comprises a pair of jaws mounted for movement towards and away from the component, each jaw carrying means for engaging the component, one of which is motor driven for rotating the component and both of which carry contacts for the electrical leads of the device, a motor operative to move the jaws and means when the contacts engage the leads to effect separation of the jaws. In the form shown as applied to a turret machine, the jaws 96, 137, Fig. 3, are carried on a rod 46 and a plate 136 respectively, connected by a pivoted lever 60 so as to be movable together towards and away from the component 16 by means of an air motor 86, one side of the piston of which is acted upon by a low pressure air line to close the jaws and the other side by a high pressure air line to effect rapid separation of the jaws. The jaw 96 carries an idler roller 104 and the jaw 137 a pair of rollers 168 driven by the turret machine. On rotation of the component by the rollers, contact fingers 116, 169 are brought into engagement with contact pins 18 on the component. The low pressure line LP, Fig. 14, is controlled by a normally closed valve 192 operated by a solenoid 190 on closure of a cam operated switch 198. The high pressure line HP is controlled by a normally open valve 196 operated by a solenoid 194, the circuit of which is opened by a switch 204B controlled by a relay which also closes a switch 204A when it is energized by the closing of switch 198. When the contacts 116, 169 encounter the pins 18, current flows through the filament and energizes a relay 200 opening a contact 200A to de-energize the relay 204, thereby cutting off low pressure air and allowing the high pressure air to retract the jaws. In a modification, low pressure air is continuously applied, the greater pressure of the high pressure air overcoming this to cause separation of the jaws. If the contacts 116, 169 fail to complete the circuit due e.g. to the absence of a component or the failure of a filament, the cam operated switch 202 is opened after one complete revolution of the component by the rollers to effect separation of the jaws. U.S.A. Specification 2,744,671 is referred to.
