The cover plate 34 closing the insertion hole 31a from above the insertion hole 31a is fixed by a screw 61. The discharge holes 32a and 33a provided at the four corners of the accommodation holes 32 and 33 are discharge holes that shorten the processing time of the accommodation holes 32 and 33. Semicircular holes 32b, 33b are provided on one side of the housing holes 32, 33, so that the brush circuit boards 70, 80 can be easily taken out from the housing holes 32, 33.
The movable blade 40 is held between the guide plate 31 and the fixed blade 50, and its moving direction is guided by the guide plate 41. The moving blade 40 has a fitting hole 40a through which the slider 42 can be inserted to a position corresponding to the insertion hole 31a of the guide plate 31. Further, at positions corresponding to the receiving holes 32, 33 of the guide plate 31, there are provided blade holes 45 into which lead wires of electronic components can be inserted. Blade portions 45a are provided at both ends of the inner peripheral edge of the moving blade 40 forming the blade hole 45 in the moving direction. Between the blade 45a and the fixed blade 50, the lead wire of the electronic component may be cut to a predetermined length and bent at a predetermined angle.
The slider 42 is composed of a large-diameter portion 43 and a small-diameter portion 44, and has a through hole 42a in the axial direction, and the pin 26 provided on the cam plate 24 can be fitted from below. The upper end surface of the slider 42 is pressed by the cover plate 34 and prevented from falling off from above the inclined plate 30. Further, the lower end surface of the large diameter portion 43 is tied to the upper end surface of the moving blade 40, and the slider can be prevented from falling off from the lower side of the inclined plate 30. The gap formed in the moving direction of the moving blade 40 is made extremely small, and notches 44a are provided at both ends of the slider 42 in the radial direction of the small diameter portion 44, such that the slider 42 is fitted into the fitting hole 40 a.

The fixed blade 50 has an insertion hole 50a, and the slider is inserted into the insertion hole 50a at a position corresponding to the fitting hole 40a so as to be reciprocatingly movable. At a position corresponding to the blade hole 45, there is a wire hole 51 through which a lead wire of an electronic component can be passed.
The printed circuit boards 70 and 80 are constituted by 3 printed circuit boards 71 and 81, respectively. As shown in fig. 7, the green sheet 70 is divided into individual green sheets 71 by removing a frame 72 provided around the green sheet 71. As shown in fig. 8, electronic components 73 such as capacitors and resistors are inserted into predetermined positions of the printed circuit boards 71 and 81, and lead wires 74 project from the lower side of the printed circuit board 71.
The sequence of mounting the electronic components to the printed circuit board is described below.
(1) The pin 26 is fitted in the through hole 42a of the slider 42, and the inclined plate 30 is mounted in the apparatus body 10. At this time, the movement of the inclined plate 30 in the horizontal direction is restricted by the housing 11 and the positioning pin 14.
(2) The printed circuit boards 70 and 80, into which electronic components are manually inserted, are fitted into the receiving holes 32 and 33 of the guide plate 31 while inserting the lead wires of the electronic components into the blade holes 45 and the wire holes 51.
(3) When the operator turns ON a start switch not shown in the drawing, the rod 21 is moved back and forth in the direction A, B in fig. 2 by the air pressure in the air cylinder. As the lever 21 is moved back and forth, the pin 23 moves into the cam groove 24a, and the guide plate 25 guides the cam plate 24 to move back and forth in the C, D direction in fig. 2, which C, D direction is perpendicular to the A, B direction in fig. 2, which is the direction in which the lever 21 is moved back and forth. As the cam 24 reciprocates, the moving blade 40 also reciprocates. As the rod 21 reciprocates, the pin 23 moves in the cam groove 24a in the direction a in fig. 2, the cam plate 24 moves in the direction C in fig. 2, and one end of the blade portion 45a provided at both ends of the knife hole 45 and the fixed knife 50 cut one end of the lead wire and bend the lead wire toward the other lead wire. The pin 23 is moved in the direction a in fig. 2 and then returned in the direction B, the cam plate 24 is moved in the direction D in fig. 2, and the other end of the blade portion 45a and the fixed blade 50 cut the other side of the lead wire and bend the other side of the lead wire. In this way, the lead wires protruding from the lower side of the green sheets 70 and 80 are cut by the blade portion 45a of the movable blade 40 and the fixed blade 50 so as to protrude slightly from the lower side of the green sheets 71 and 81 as shown in fig. 8, and are bent at a certain angle in the direction facing each other. The bent shapes of the lead wires with respect to each other are to prevent the lead wires from coming into contact with the wiring of the circuit board of the printed circuit board base 71 or other incorporated electronic components.
Fig. 9 is a sectional view showing a state where the lead wires 74 are inserted into the printed circuit board 70. When the movable blade 40 is moved in the leftward direction in the drawing from this state, the lead wire 74 on the right side is cut as shown in fig. 10, and the tip of the cut lead wire is bent by the inclined surface 45b formed on the blade 45a as shown in the drawing. Then, the left lead wire 74 in fig. 10 is cut similarly by the movement of the movable blade 40 in the reverse direction, and the cut tip may be bent to the opposite side of the right lead wire.
(4) After the cutting and bending of the lead wires are completed, the green sheets 70 and 80 are taken out from the mounting apparatus. The taken-out green sheets 70 and 80 are divided into green sheets after electronic components are soldered to the green sheets 70 and 80 by solder.
Then, by repeating the operation processes of (2) to (4), the electronic component can be efficiently mounted on the printed circuit board.
In this embodiment, the electronic components are manually inserted into the printed circuit boards 70 and 80, and the operator turns ON the start switch to drive the air cylinder 20. In the present invention, the insertion of the electronic components into the green sheets 70 and 80 and the driving of the air cylinders can also be performed automatically.
In addition, the shape and number of the receiving holes provided in the guide plate of the present invention for receiving the green sheets are changed corresponding to the loaded green sheets. With this change, the blade portion, i.e., the blade hole position of the moving blade and the wire hole position of the fixed blade, also changes.
In this embodiment, the air cylinder uses air to drive the piston to move, but in the present invention, other fluids may be used to drive the piston to reciprocate.
In the present embodiment, the blade hole 45 into which the pair of lead wires of each electronic component are inserted together is provided in the movable blade 40, and the movable blade 40 is reciprocated; the lead wires are bent to face each other while being cut. However, in the present invention, when the density of wiring of the printed circuit board or mounting of electronic components is low, the blade holes into which the pair of lead wires of each electronic component are inserted may be provided in the blade portion, that is, in the movable blade, and the lead wires may be bent in opposite directions while being cut by the reciprocating movement of the movable blade.
In the present embodiment, the moving blade 40 moves forward and backward to cut one lead wire; however, in the present invention, the lead wire may be cut by moving the lead wire once.
