Board working system
View Patent ↗A system including at least one inspection machine and an NG board discharge machine which moves an NG board to a checking position visible to a worker. The system acquires positional information of a circuit board during conveyance, and stores the NG board by associating a work result for the NG board with the positional information. In this manner, the positional information of the NG board is acquired. Based on the positional information, it is determined whether or not the circuit board conveyed to the NG board discharge machine is the NG board. When the circuit board conveyed to the NG board discharge machine is the NG board, a checking-purpose working machine discharges the NG board to the checking position.
1. A board working system, comprising:
multiple working machines, circuit boards arranged on an upstream side to a downstream side of the multiple working machines are conveyed through multiple paths in a conveyance direction, and each of the multiple working machines sequentially carries out the work for the circuit boards, the multiple working machines include at least one inspection-purpose working machine which inspects the work for the circuit boards, and include a board discharge machine which has a board moving mechanism to move the circuit boards in a direction orthogonal to the conveyance direction to a checking position parallel with the multiple paths, the board discharge machine being arranged on a downstream side of the at least one inspection-purpose working machine; and
a control device including
a positional information acquisition unit that acquires positional information of each of the circuit boards,
a memory section that stores a defective board which is a circuit board of the circuit boards whose work result is determined as unsatisfactory by the at least one inspection-purpose working machine by associating the work result with the positional information acquired by the positional information acquisition unit,
a determination unit that determines whether or not a circuit board conveyed to the board discharge machine is the defective board, based on the work result and the positional information which are stored in the memory section, and
a moving mechanism operation control unit that controls an operation of the board moving mechanism and moves the defective board in the direction orthogonal to the conveyance direction to the checking position, when the determination unit determines that the circuit board conveyed to the board discharge machine is the defective board.
2. The board working system according to claim 1 ,
wherein the control device includes a display unit that causes a display device disposed in the board working system to display the work result for the defective board stored in the memory section, when the determination unit determines that the circuit board conveyed to the board discharge machine is the defective board.
3. The board working system according to claim 1 ,
wherein the at least one inspection-purpose working machines is multiple inspection-purpose working machine.
4. The board working system according to claim 1 ,
wherein with respect to the circuit boards conveyed through each of the multiple paths, the positional information acquisition unit stores a sequence and a conveying path of the circuit boards conveyed through each path, and acquires the positional information, based on the sequence and the path of the circuit boards.
5. The board working system according to claim
wherein with respect to the boards conveyed through each of the multiple paths, the positional information acquisition unit sets a symbol for distinguishing the circuit boards from each other, and acquires the positional information, based on the symbol, the path through which the circuit board having set symbol is conveyed, and the working machine which conveys the circuit board having the set symbol.
