Electronic component mounting apparatus for exchanging support blocks which support circuit boards

Abstract

An electronic component mounting apparatus is provided with a plurality of support blocks for supporting boards. A support block is automatically selected from among the plurality of support blocks and exchanged in accordance with the switching of the kind of boards to be supported by the support block, so that the time required for switching the kind of boards is reduced, thereby improving the productivity.

What is claimed is:  
     
         1 . An electronic component mounting apparatus comprising: 
 a plurality of support blocks one of which supports a board when mounting an electronic component, wherein a support block among the plurality of support blocks is automatically selected and exchanged in accordance with switching of a kind of boards.    
     
     
         2 . An electronic component mounting apparatus according to    claim 1   , further comprising: 
 a storing device for storing the plurality of support blocks; and    a support block moving device for selecting one of the support blocks stored in the storing device in accordance with the switching of the kind of boards and moving the selected support block from the storing device to a position where the board is supported by the selected support block.    
     
     
         3 . An electronic component mounting apparatus according to    claim 2   , wherein the support block moving device upward moves the support block to support the board when the electronic component is mounted on the board, and downward moves the support block to stop supporting the board.  
     
     
         4 . An electronic component mounting apparatus according to    claim 2   , wherein the support blocks are different in positions of pins for supporting the boards.  
     
     
         5 . An electronic component mounting apparatus according to    claim 1   , further comprising a single support block driving device for upward moving the support block to support the board when the electronic component is mounted on the board, downward moving the support block to stop supporting the board, and exchanging the support block with another support block.  
     
     
         6 . An electronic component mounting apparatus according to    claim 1   , wherein the support blocks are different in positions of pins for supporting the boards.
