6, 7 and 8 are schematic cross-sectional views of the present invention, when the parts 19 supplied from the separator are supplied along the supply guide holes 20-1 and 20-2 of the inserter 20. When the cylinder 21 is driven and the bottom surface 22-1 is pushed, the pressing piece 22 is rotated about the shaft 22-2, and the contact surface 22-3 is pressed against the top of the component and is supplied (19). ) So that it is not inclined and is upright, and thus the cylinder 23 is driven and pushed to the position of the operating hole 24 while being inserted into the inserting portion 20 and inserted into the fitting groove 25-1 of the pedestal 25. After aligning with the position to be inserted on the printed circuit board 26, the cylinder 27 in which the inclined surface 27-1 is integrated is driven, and the spring piece 28-3 is supported by the spring piece, which is elastically upward ( When the inclined surface 28-1 of the 28 is pushed down, the projection 28-2 of the mill piece 28 fits into the upper groove 29-1 of the tongs 29, so that the space between the tongs 29 is widened. Shaft (29-2) The lower groove 29-3 is narrowed while the upper and lower stirring functions to hold the upper portion of the part 19.

Then, while the cylinder 21 reversely drives the pressing piece 22 to its original state, the contact surface 22-3 is released while pressing the upper part of the component 19, and the cylinder 23 reversely drives. The parts 19 are not caught by the guide holes 20-3, 20-4, and 20-5 of the inserting part 20, and the parts 19 are held in the state where the upper part is caught by the tongs 29. The insertion part 20 is returned to its original state while being left in the position of the operation hole 24 to prepare to receive the next part, and then an operation cylinder not shown in the drawing is driven to drive the upper thread part 34-1. An operating piece that can freely limit the working distance by the sensor 35 by inserting the adjusting nuts 3 and 3-1 having the washer 31 in which the sensor shielding plate 31-1 is integrated therebetween. By pressing down 34, the pin 32-1 is inserted into the long hole 33-1 of the guide wall 33, thereby limiting the operation distance of the upper and lower sides, and connected with the operating piece 34 and the pin 34-2. Up and down The bottom 32-2 of the actuating part 32 is pushed down the top 29-4 of the tongs 29 so that the component 19 is mounted on the printed circuit board 26.

In the present invention, when the printed circuit board 26 is supplied in the automatic mode and the start switch S4 is connected, the X-axis position motor depends on the position where the component 19 should be inserted on the printed circuit board 26. The drive unit 5 and the Y-axis position motor drive unit 6 are operated to adjust the position according to the insertion order, and the parts 19 supplied to the inserting unit 20 are moved to the cylinders 21, 23, and 27. When it is confirmed that there is no abnormality in the sensor unit 4 in which the sensing state of each sensor is detected while driving or reverse driving, it is driven to drive the operating cylinder 29 and the operating unit 32. ) By mounting down the component 19 on the printed circuit board 26. The central processing unit 3 sends signals to the decoder circuits IC25 and IC25a, and the switches and sensors are connected to each other. Read the bungee at once to get it up and running A motor driving unit (8), the motor was driven to potoyi through the isolator circuit (9), (16) to prevent the counter electromotive force.

At this time, the Interrupt switches (S1) to (S11) input from the 3rd connector to the 13th connector of the 250th address are the ones in which the smaller numbered switch takes precedence over the larger numbered switch. When the interlock switch is connected, the central processing unit 3 reads the address 250 to confirm which switch is connected. First, the operation corresponding to the function of the switch is performed first. It is.

In the manual mode, when the position and the order of X coordinate and Y coordinate are not memorized in the program memory 1 or when the type of the printed circuit board is changed, the position of the X coordinate and Y coordinate is operated while operating semi-automatically or manually. And the sequence of memories to be carried out in the automatic mode accordingly. When the switches S12 and S14 are connected to move to the right or left on the X coordinate or forward or backward on the Y coordinate, the or gate is connected. "L" is input to one side of (O18) and one side of the NAND gate Na1, and the "H" value through the exclusive OR gate EX1 is input to the other side of the NAND gate Na1, and the clock generator circuit Since the clock pulse "H" is applied through the IC39 and the clock circuit IC40, the output terminal of the NAND gate Na1 becomes the "L" value so that there is no signal for moving to the left (back) of the X (Y) axis. And a signal is sent to move the "H" value through the or gate O18 to the right (front) of the X (Y) axis. On the contrary, when the switches S and S15 are connected, “H” is input to one side of the OR gate O18 and the NAND gate Na1, and passes through the exclusive OR gate EX1 to the other side of the NAND gate Na1. When " H " is input, the clock pulse " H " through the clock generator circuit IC39 and the clock circuit IC40 is inputted to the or gate I18 as " L " No signal is sent to move to the left (back) of the X (Y) axis through the NAND gate Na1.

In this way, the parts are automatically mounted on the printed circuit board while continuously operating in the auto mode in the order stored in the program memory. When the type of the printed circuit board is changed, the X and Y axis motors are used as the manual mode. After the operation, the position is memorized, and after the end of the process, it is operated by the automatic mode by the memorized method, and the sensor shield plate (34-1) on the upper shaft screw portion 34-1 of the operating piece 34 moved up and down by the operation cylinder. The sensor 35 is sensed by arbitrarily adjusting the adjusting nuts 30 and 30-1 by installing the adjusting nuts 30 and 30-1 sandwiching the washers 31 having the integrated body 31-1). By operating the cylinders by the signal of the sensor unit 4 located in each part, such as limiting the working distance by the precise operation is made to perform a stable work quickly and publicly.
