Abstract

PURPOSE:To effectively detect insertion of a lead of an electronic component by bringing split ends of a detecting piece inserted by the lead into contact in a state of bridging between adjacent patterns, and bringing all patterns into electric continuity. CONSTITUTION:An end of a detecting piece 59c is separated upward from a corresponding pattern 60b and not brought into contact therewith in a state that the piece 59c is not inserted from above by a corresponding lead 11b. An IC 11 picked up by a head mechanism is mounted from this state on a circuit board 12. When leads 11a are inserted to corresponding through holes 12a, the piece 59c is pressed down by the lead 11b, brought into contact with the adjacent patterns 60b from above, and brought into electric continuity. Thus, bending of the piece 59c is not feared, and a sureness of the detecting operation is improved.

A pair of rotating members supported by the rotating member, and a detecting unit arranged on the tip surface of each rotating member for detecting the completion of the inserting operation of all the lead wires into the circuit board. Are arranged so as to correspond to all of the above-mentioned lead wires, respectively, can be independently pushed by the inserted lead wires, have a spring property in electrical conduction with each other, and have their tips divided into two. A detection piece and a plurality of pattern portions arranged in an electrically insulated state from each other,
All of the pattern portions are brought into an electrically conductive state by contacting with each other in a state where the tip end portions of the detection piece pushed in by the lead wires are hung over the pattern portions adjacent to each other. And a detection board.

Further, in the mounting apparatus according to the present invention,
The detection piece is composed of a conductive arch-shaped spring member, and is elastically held in a posture of being separated from the pattern portion in a state in which the lead wire is not pressed into the spring member. Further, in the mounting apparatus according to the present invention, each of the detection pieces is arranged so as to be able to simultaneously contact adjacent pattern parts, and all the pattern parts are electrically connected to each other in a state where all the lead wires are inserted. It is characterized in that at least one lead wire is made non-conductive in a state where at least one lead wire is not inserted.

[0006]

As described above, in this mounting apparatus, since the detecting pin having the spring property is used as the detecting means without using the detecting pin which is slidably driven by the insertion of the lead wire, the detecting pin is used. As described above, there is no possibility of bending, and the reliability of the detection operation is improved. Further, since the detection piece whose tip is divided into two parts is used in this detection operation, even if the detection piece comes into contact with the detection substrate at an angle during this detection operation, The two divided tip portions can surely contact the pattern portions adjacent to each other, and the occurrence of detection error can be surely eliminated.

1b is configured to correspond to the left column in the drawing and the right column in the diagram, respectively, but since both are symmetrical, in the following description, only the portion corresponding to the left column in the drawing will be taken out. explain.

That is, this detection mechanism 58 is shown in FIGS.
As shown in FIG. 5, a detection member 59 is formed by cutting a conductive thin plate made of phosphor bronze and having a spring property into a shape described later. As shown in FIG. 6, the detection member 59 is formed in an arch shape, one end of which is fixed to the inner side surface of the clinch member 54a in a standing state, and the other end of which is the upper end surface of the corresponding rotation base 51a. It is set to float right above.

That is, the detecting member 59 corresponds to the flat main body 59a fixed to the inner surface of the clinch member 54a and the lead wire 11b extending from the main body 59a in an arch shape to detect the insertion state. , a plurality of detection pieces which is branched via a branching slit 59b so as to position independently of these immediately under 59c (59c ₁ ~59c _n:
However, n is a lead wire 11 provided on each side edge of the IC 11.
(the number of b)). here,
Each arch-shaped detection piece 59c _n is set so that its top is located immediately below the through hole 12a through which the corresponding lead wire 11b is inserted. Further, the tip end portion of each detection piece 59c _n (that is, the portion located on the tip end side with respect to the portion located immediately below the through hole 12a) is divided into the first and second division pieces 59c via the division slit 59d. It is divided into two parts, _na and 59c _nb .

Since the detection member 59 is constructed in this manner, the plurality of detection pieces 59c _n of the detection member 59 are inserted into the corresponding lead wires 11b through the corresponding through holes 12a. By being pushed down by 11b, each tip is biased downward. On the other hand, the detection mechanism 58 is provided on the upper end surface of the rotation base 51a.
It has 0. The detection substrate 60 includes an insulating substrate body 60a and a conductive pattern portion 60b (6 formed on the substrate body 60a in a predetermined pattern).
It is constructed from 0b ₁ ~60b _{n + 1)} and. here,
As shown in FIG. 5, a plurality of pattern portions 60b are arranged along the arrangement direction of the plurality of detection pieces 59c _n so as to be spaced apart from each other, and one detection piece 59c _n is adjacent to each other at the same time. It is arranged so that it can contact the portion 60b _n . The number (n + 1) of the pattern portions 60b _n , as shown, is set to be one more than the number (n) of the detection pieces 59c.

The pattern portion 60b ₁ located at one end
Is connected to a power source (V
cc) and the pattern portion 60b located at the other end
_Although not shown, _{n + 1} is electrically connected to the pattern portion located at the other end of the plurality of pattern portions arranged corresponding to the lead wire 11b in the right column. The pattern portion located at one end of these pattern portions arranged corresponding to the lead wire 11b in the right column is grounded via the LED 61. The pattern portions 6 other than those located at both ends
0b _{2 to} 60b _n are set to be insulated from each other independently.

Since the detection mechanism 58 is constructed in this way, as shown in FIG. 4, when the detection piece 59c cannot be pushed in by the corresponding lead wire 11b from above, the tip of the detection piece 59c is Pattern part 60
It is spaced upward from b and does not contact them. From this standby state, as will be described later, the IC 11 picked up by the head mechanism 18 is mounted on the circuit board 12, and the IC 1
When each lead wire 11b of No. 1 is inserted through the corresponding through hole 12a, the detection piece 59c located below each through hole 12a.
Are pushed down by the corresponding lead wires 11b and come into contact with the pattern portions 60b adjacent to each other from above, so that they are brought into an electrically conductive state.

Here, when all the lead wires 11b are inserted through the corresponding through holes 12a and protrude below the circuit board 12, all the detection pieces 59c are corresponding lead wires 1c.
It is pushed down by 1b, so that all pattern parts 6
As shown in FIG. 7, 0b is brought into an electrically conducting state through all the detection pieces 59c that are in contact with them. In this way, the voltage from the power supply (Vcc) is supplied to the LED 61. As a result, the LED 61 is turned on when the IC 11 is mounted on the circuit board 12 without error.

On the other hand, when at least one lead wire 11b is not inserted through the corresponding through hole 12a and mounting fails, the detection piece 59c corresponding to the lead wire 11b not inserted through the through hole 12a is pushed down. Therefore, the pattern portions 60b adjacent to each other at the corresponding places do not come into contact with each other. In this way, the voltage from the power supply (Vcc) is not supplied to the LED 61. As a result, the LED 61 is turned off when the mounting operation of the IC 11 has failed.

In this embodiment, the tip of each detection piece 59c _n is divided into two, as described above.
Here, if it is not divided into two, as shown in FIG. 8, if the predetermined detection piece 59c _n is tilted for some reason, for example, the operator's hand touches it, for example, Even if the lead wire 11b is inserted properly and the detection piece 59c _n is pushed down, one end X of the tip of the detection piece 59c _n contacts the corresponding pattern portion 60b _n , but the other end. The part Y does not contact the corresponding pattern part (that is, the adjacent pattern part) 60b _{n + 1} . In other words, the lead wire 1 is good, for example.
Even if 1b is inserted, the pattern portions 60b _n and 60b _{n + 1} adjacent to each other at corresponding positions are not electrically connected to each other and are maintained in an insulated state. As a result, the voltage from the power supply (Vcc) is not supplied to the LED 61, the LED 61 is turned off, and the IC 11
It will be erroneously displayed that the mounting operation of failed.

However, in this one embodiment,
As described above, each detection piece 59c_nThe tip of the

Here, again, as shown in FIG.
The ED 61 is attached to the outer peripheral surface of each of the second attachment main bodies 46 in an exposed state, and in the state of facing only the LED 61 of the clinch mechanism 43 in the clinching position, one ED 61, for example, , Phototransistor 62
Are arranged. On the other hand, on the side of the phototransistor 62, although the details are not shown, the base of this is
It is arranged so as to face the LED 61, its emitter is connected to the power supply V _CC , its collector is connected to the latch circuit, and it is grounded via a predetermined resistor. In this way, when the LED 61 emits light, the phototransistor 62 becomes conductive by receiving the light from this.
The input potential to the latch circuit is increased, and the latch circuit is configured to latch the value when the input potential exceeds a predetermined threshold value. This latch signal is
It is sent to the control unit 21 and is set so as to be a clinch operation permission signal (starting signal) described later.

The latch state is set so that it is released along with the lowering operation of the clinch body 49 of the clinch mechanism 43A executed after the clinch operation. As described above, in this embodiment, the detection result of the detection mechanism 58 is transmitted to the control unit 21 via the LED 61 and the phototransistor 62 which is arranged so as to face the LED 61 in a separated state. It will be. As a result, even if the second rotary table 42 rotates and the clinch mechanisms 43 ₁ to 43 ₁₀ are sequentially positioned at the clinch positions, the control unit 21 and the detection mechanism 58 are directly connected by the connection cable.
