Method and apparatus for mounting component

Abstract

According to the present invention, a control device and a circuit board moving device controlled in operation by the control device for holding a circuit board are provided, whereby the circuit board moving device is moved to bring a component mount position on the circuit board closest to a recognition device after the circuit board moving device is moved to bring the component mount position closest to a component feed position. In the state, a circuit board mark formed on the circuit board is detected, thereby recognizing a position of the circuit board. A transfer distance for the component by a component hold device from the recognition device to the component mount position is thus shortened, enabling high-speed mounting with higher accuracy.

1 . A component mount method for carrying out by a component mounting apparatus which comprises a transfer device for transferring an object to be mounted in a transfer direction along a linear transfer path, at least two component feed devices fixedly disposed at both sides ofthe transfer path via the transfer path in a direction orthogonal to the transfer direction for supplying components to be mounted to the object and, a component hold device which is movable both in the transfer direction and the direction orthogonal to the transfer direction, holds the component from the component feed device and mounts the component to the object, 
 the component mount method comprising that after the object is moved towards the component feed device for supplying the component to be held by the component hold device in order to mount the component to the object, the component is mounted by the component hold device to the object.    
     
     
         2 . A component mount method according to  claim 1 , wherein after the object is moved toward the component feed device before mounting the component, recognition operation of an arrangement position of the object is carried out so as to correct a movement amount of the component hold device with respect to a component mount position on the object.  
     
     
         3 . A component mount method according to  claim 1 , wherein in a case when the component mounting apparatus comprises recognition devices arranged at both sides of the transfer path via the transfer path in the direction orthogonal to the transfer direction, for recognizing the component held by the component hold device before being mounted, the object is brought to a position where a distance between the recognition device and a component mount position on the object is minimum after the object is moved toward the component feed device and before the component is mounted.  
     
     
         4 . A component mount method according to  claim 3 , wherein after the object is brought to the position where the distance between the recognition device and the component mount position on the object is minimum and before the component is mounted, recognition operation of an arrangement position of the object is carried out in order to correct a movement amount of the component hold device with respect to a component mount position on the object.  
     
     
         5 . A component mount method according to  claim 1 , wherein in a case when the component hold device has a plurality of component hold members for holding the components and the component mount operation is carried out after component hold operation by the component hold members, the object is moved to the component feed device which is to supply the component to be held by the component hold member which holds the component last.  
     
     
         6 . A component mount method according to  claim 4 , wherein in a case when the component hold device has a plurality of component hold members for holding the components and the component mount operation is carried out after component hold operation by the component hold members, the object is moved to the component feed device which is to supply the component to be held by the component hold member which holds the component last.
