Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for supplying electronic components used in an inspection device having a measuring unit for measuring the characteristics of molded electronic components such as ICs, capacitors and discrete devices.

[0002]

2. Description of the Related Art ICs, capacitors, pooled in one place,
Various types of feeders of this type have been proposed in the past, which reliably separate molded electronic components such as discrete devices (hereinafter collectively referred to as electronic components) one by one and supply them to a predetermined position such as a measuring unit. As one example thereof, an electronic component supply device described in Japanese Utility Model Publication No. 7-31179 is known.

As shown in FIGS. 25 (a) and 25 (b), this supply device normally projects into an inclined chute 1 for supplying electronic components 2a, 2b ... And a downstream passage of the chute 1. By doing so, the first electronic component 2a from the bottom is locked, and the locking pin 3 that releases the locking of the first electronic component 2a at the time of supplying to the measurement unit, and the locking pin 3 is arranged above the locking pin 3. The press pin 4 that presses the second electronic component 2b by lowering it in conjunction with the locking pin 3 at the time of supply, and raises when the first electronic component 2a does not move within a certain time during supply. As a result, the push-up pin 21 for pushing up the second electronic component 2b and sandwiching it with the pressing pin 4 is provided. In addition, 20 is a detection means 20 for detecting the movement of the first electronic component 2 a, and 22 is a drive device such as a solenoid for driving the push-up pin 21.

In such a structure, the electronic components 2a,
The supply operation of 2b ... Is performed by operating the locking pin 3 and the pressing pin 4 by an appropriate driving device such as a solenoid (not shown) according to a supply signal. In this case, the state shown in FIG. 25A, that is, the locking pin 3 locks the first electronic component 2a and the pressing pin 2b is positioned above the second electronic component 2b in a non-contact manner. In, when the locking pin 3 and the pressing pin 4 are operated, the locking pin 3 rises and retracts from the passage, and the locking of the first electronic component 2a is released. Therefore, the first electronic component 2a slides down along the chute 1 and is supplied to the measuring unit and the like. When the locking pin 3 operates, the pressing pin 4 descends in tandem with this.
The second electronic component 2b is pressed. Therefore, the second and subsequent electronic components 2b ... Are not supplied to the measuring section.

When the first electronic component 2a passes below the locking pin 3, the detecting means 20 detects the movement of the electronic component 2a and sends the detection signal to the controller. Upon arrival of this detection signal, the control unit confirms that the electronic component 2a has been normally supplied to the measuring unit and the like and sends a signal to stop the driving device for the locking pin 3 and the pressing pin 4. Therefore,
The locking pin 3 and the pressing pin 4 return to the original state again. Therefore, the second electronic component 2b is released from the pressing pin 4, slides down to the position of the locking pin 3, and is locked by the locking pin 3 to become the first electronic component 2a. Then, by repeating such an operation, the electronic component 2
Can be automatically supplied to the measuring unit or the like at a predetermined timing.

Since the electronic component 2 is formed by molding the element with synthetic resin, if burrs 7 and 8 are generated along the parting line of the mold during manufacturing, the burrs 7 and 8 interfere with each other and the second Electronic component 2b is the first electronic component 2a
May be locked and stuck (this is commonly called "device jam"). It also stops due to friction with the passage. In that case, the detection means 20 uses the electronic component 2a.
Is not detected, the detection signal is not sent to the control unit,
When a preset time has elapsed from the start of supply, the control unit determines that the supply is impossible and sends a drive signal to the drive device 22. When the drive device 22 is driven by the drive signal, the push-up pin 21 is operated to cause the push-up pin 21 to project into the passage of the chute 1 as shown in FIG. Therefore, the second electronic component 2b is pushed up by the push-up pin 21 and pressed against the push pin 4. This makes Bali 7,
The engaged electronic components 2a and 2b can be reliably separated by 8, and the first electronic component 2a can be smoothly and reliably supplied. Note that, when the first electronic component 2a safely passes under the locking pin 3 and the detection means 20 detects this, the locking pin 3, the pressing pin 4, and the push-up pin 21 are shown in FIG. 25 (a). It returns to the state and stands by for the supply of the next electronic component 2b.

[0007]

In the above-mentioned conventional electronic component supply apparatus, when the movement of the first electronic component 2a from the bottom is restrained by device jam or friction, 2
Since the second electronic component 2b is displaced by the push-up pin 21 in the direction perpendicular to the supply direction of the electronic component 2 and separated, there is an advantage that the electronic component 2 can be reliably supplied. There is a problem that when the second electronic component 2b is displaced upward depending on the burrs or the overlapping of the burrs and the electronic component 2, not only the burrs 7 and 8 but also a part of the electronic component 2a or 2b itself is damaged. It was That is, the second electronic component 2b itself or the burr 8
When the second electronic component 2b is displaced upward when the first electronic component 2a itself or the lower side of the burr 7 is displaced, not only the burr 7, 8 but also the burr 7, 8 are broken. The mold part of 2a or 2b also breaks or cracks together. In particular, such damage or cracks in the mold part occur frequently because the electronic component 2 itself is becoming smaller and thinner, and if the mold part is damaged, it is originally a good product in terms of performance. However, since it loses its commercial value, it must be discarded as a defective product.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide an electronic component that can be reliably supplied even if it is a mold type electronic component having a burr. It is to provide a supply device.

The cam 144 has a cam surface 144a as shown in FIG. 10A, and the first holding device 76 is provided.
Corresponding to the cam followers 111, 112 of the screw rod 142
It is fixed to b. The cam 145 is a tubular body, has a tapered cam surface 145a formed on the upper end side, and is fixed to the screw rod 142b corresponding to the cam followers 135 and 136 of the second holding device 77. These cams 144
When the electronic component 2 is supplied to the passage 33, the passages 145 and 145 pass through the tips of the pair of holding pieces 108 and 109 of the first holding device 76 and the pair of holding pieces 133 and 134 of the second holding device 77. 33, each of which is kept in a retracted state,
When the electronic components 2 in 3 are sequentially supplied to the measuring section, the retracted states of the pair of holding pieces 108 and 109, 133 and 134 are sequentially released.

The cam 146 is formed into a conical tubular body at the lower end side thereof, is located between the cams 144 and 145, and has a tapered cam surface 146a. This cam 14
After the stopper 92 withdraws from the passage 33, the first holding device 76 is operated to operate the pair of clamping pieces 10.
8 and 109 are evacuated from the passage 33.

The member 147 is formed into a cylindrical body, is slidably fitted from the upper side to the outer periphery of the cam 146, and is urged downward by the compression coil spring 148 to be pressed against the cam 146. There is. This member 147 is
When supplying the electronic component 2 in the passage 33, the pair of cam followers 111 and 112 are pressed downward to move the slide member 85 downward via the first holding device 76. The cam surface 146a of the cam 146 always projects below the member 147.

Further, below the front surface of the carrying member 34, the rotating member 91 of the stopper device 75 is rotated downward after the slide member 85 is moved downward when the electronic component 2 is supplied, and the stopper 92 is passed through. A cam 149 (FIGS. 1 and 3) for temporarily retracting from 33 is integrally provided so as to correspond to the cam follower 94. The cam 149 has a trapezoidal shape in a side view, and the upper slope forms a cam surface 149a.

Next, the operation of the supply device 30 having the above structure will be described mainly with reference to FIGS. Figure 1
0 (a) is a diagram showing the positional relationship between the cam and the cam follower before the electronic component 2 is supplied to the passage 33, (b)
FIG. 4 is a diagram showing a state of a stopper and a sandwiching piece. In this state, the cam shaft 142 is held at the upper limit position. At this time, the cam follower 94 of the stopper device 75 is
The stopper 92 a of the stopper 92 is inserted into the passage 33, which is located above 49. In addition, the first holding device 7
The pair of cam followers 111 and 112 of 6 are brought into pressure contact with the peripheral surface of the cam 144, and the holding members 114 and 115 of the pair of holding pieces 108 and 109 are retracted from the passage 33. Further, the pair of cam followers 135 of the second holding device 77,
136 is pressed against the peripheral surface of the cam 145, and the pair of clamping pieces 1
The clamps 138 and 139 of 33 and 134 are retracted from the passage 33.

In this state, when the electronic component 2 is supplied from the device housing portion to the passage 33, the electronic component 2 falls in the passage 33 due to its own weight, and the electronic component 2a initially supplied is locked by the stopper 92. The part 92a drops and stops, and the second electronic component 2b from the bottom drops and stops on the part 92a. Hereinafter, the electronic components 2c, 2d ...
・ Drops on the electronic component supplied immediately before and stops.

Electronic parts 2a, 2 supplied into the passage 33
When b ... stops in the middle of the passage 33 due to mold burr, friction, etc., and a device jam occurs, the jam eliminating device 36 shown in FIG. 6 eliminates the device jam. That is, in the jam eliminating device 36, since the holding member 51 is reciprocally rotated by supplying the air pressure to the air cylinder 52, the pressing piece 59 provided at the tip of the elastic member 53 has the groove 37.
From above, the front surface of the electronic component 2 that has entered the passage 33 and stopped in the passage is repeatedly pressed or tapped. At this time, the pressing piece 59 is elastically deformed in the plate thickness direction and is also elastically deformed upward, and a force for moving the electronic component 2 upward is generated. When such an operation is repeated several times, the electronic component 2 is separated, the device jam is eliminated, and after the jam is eliminated, the electronic component 2 is normally dropped and stored in the passage 33.

Here, if the pressing piece 59 is formed so as to be directed obliquely downward, it is not preferable because it is elastically deformed downward and the electronic component 2 is moved in the direction in which a device jam occurs. Further, when it is formed horizontally, the direction of elastic deformation when pressed against the electronic component 2 is not constant, which is not preferable. Further, in order to facilitate upward elastic deformation of the pressing piece 59, it is preferable to increase the elasticity of the elastic member 53 or to form the pressing piece 59 long to facilitate elastic deformation.

When the electronic component 2 is normally stored in the passage 33, the stopper device 75, the first,
By operating the second holding devices 76 and 77 and the slide device 78 at a predetermined timing, the electronic components 2 are sequentially discharged from a lower one at a predetermined interval and supplied to the measuring unit. The operation will be described below with reference to FIGS. 11 to 13.

When supplying the electronic component 2 to the measuring section, first, the first holding device 75 is operated. That is, when compressed air is supplied to one air port 160 (FIG. 4) of the air cylinder 141 to lower the cam shaft 142, the cam 14
4 moves below the pair of cam followers 111 and 112. Therefore, the cam followers 111 and 112 are shown in FIG.
As shown in (a), the distance becomes narrower by moving from the position of the broken line to the position of the solid line. This is because the two blocks 106 and 107 (FIG. 5) of the first holding device 75 are urged in the directions toward each other by the spring force of the tension coil spring 113, so that the blocks 106 and 107 are fixed. This is made possible by moving the sliders 101a and 101b that are present along the slide groove 102 of the guide member 100 in the approaching direction. As a result, the pair of clamps 114, 11
5 is the first electronic component 2 from the bottom after entering the passage 33.
Hold a. FIG. 11 shows this state.

Further, when the cam shaft 142 descends, as shown in FIG.
As shown in FIG. 2A, the cam surface 146a of the cam 146 contacts the cam followers 111 and 112, and the cam 145 moves below the cam followers 135 and 136. At this time,
The member 147 is provided at its lower end surface with the cam followers 111, 112.
Press down. When the cam followers 111 and 112 are pressed downward by the member 147, the stopper device 75
The slide member 85 (FIG. 5) of the slide device 78 to which the first holding device 76 is attached moves downward along the rail 86. When the slide member 85 moves downward, the cam follower 94 of the stopper device 75 causes the cam 149 to move.
In order to ride on the cam surface 149a of the stopper 92, the stopper 92 integrally rotates with the rotating member 91 downward by a predetermined angle, and the stopper 92
Exit a from the passage 33. Therefore, the first electronic component 2a from the bottom is released from the locking by the locking portion 92a. In this state, the first electronic component 2a is still held by the pair of clamps 114 and 115, and therefore does not drop.

On the other hand, as the cam shaft 142 descends, the cam 14
When 5 moves below the cam followers 135 and 136,
As shown in FIG. 12, the cam followers 135 and 136 move from the position indicated by the broken line to the position indicated by the solid line, and the distance between them becomes narrow. This is the two blocks 130, 13 of the second holding device 77.
1 (FIG. 5) are urged in the directions approaching each other by the spring force of the tension coil spring 137, each block 13
Sliders 122a and 12 to which 0 and 131 are fixed
2b is moved by moving in the direction of approaching along the slide groove 123 of the guide member 121. As a result, the pair of clamps 138, 139 enters the passage 33 and clamps the second electronic component 2b from the bottom. FIG. 12 shows this state.

Further, when the cam shaft 142 descends, as shown in FIG.
As shown in FIG. 3A, the cam 146 enters between the pair of cam followers 111 and 112, so that these cam followers 111 and 112 move over the cam surface 146a of the cam 146 and move to the outer peripheral surface of the cam 146. Therefore, the pair of cam followers 111, 112 moves from the position indicated by the chain double-dashed line to the position indicated by the solid line, retracts the pair of clamps 114, 115 from the passage 33, and releases the first electronic component 2a from the bottom. . As a result, the electronic component 2a drops and is supplied to the measuring section. At this time, since the locking portion 92a of the stopper 92 is retracted from the passage 33, the electronic component 2a
It does not prevent the fall of. The slide member 85
Descends and moves to the lower limit position, so that the pair of holding pieces 108 and 109 of the first holding device 76 and the second holding device 7
The distance d between the pair of sandwiching pieces 133 and 134 of FIG.
It becomes larger than the interval d0 in the initial state shown in (b) (d> d0).

When the first electronic component 2a from the bottom drops from the passage 33 and is supplied to the measuring portion, compressed air is supplied to the air port 161 (see FIG. 4) of the air cylinder 141 to move the cam shaft 142. Raise to the upper limit position. When the cam shaft 142 stopped at the lower limit position is raised, the stopper device 75, the first and second holding devices 76 and 77, and the slide device 78 operate at a predetermined timing and in the opposite manner to the above, The initial state shown in FIG. 10 is restored. That is, when the cam shaft 142 starts to rise, first, the cam 146
Moves above the pair of cam followers 111 and 112, so that the pair of holding pieces 108 and 109 move in the direction of approaching each other, and the holding elements 114 and 115 enter the passage 33. When the cam 146 moves upward, the pressing state of the cam followers 111 and 112 by the member 147 is also released, so that the slide member 85 moves up to the upper limit position by the spring force of the tension coil spring 88 (FIG. 5). . Therefore, the cam follower 94 of the stopper device 75 moves above the cam 149, the rotating member 91 rotates upward due to the spring force of the tension coil spring 95, and the locking portion 92a of the stopper 92 enters the passage 33 again. Let

When the cam shaft 142 further rises, the cam 1
Reference numeral 45 moves between the pair of cam followers 135, 136 to move the cam followers 135, 136 in the direction of separating them, so that the pair of clamps 138, 138 withdraw from the passage 33. Then, when the cam shaft 142 moves to the upper limit position, the cam 144 causes the pair of cam followers 111,
Since it moves between 112, a pair of clamps 114, 11
5 exits the passage 33 and thus returns to the initial state shown in FIG. Therefore, when the cam shaft 142 is repeatedly moved up and down, the electronic components 2 in the passage 33 can be sequentially discharged from the lower one at a predetermined interval and supplied to the measuring unit.

As described above, in the supply device 30 according to the present invention, when the stopper 92 is retracted from the passage 33 and the first electronic component 2a from the bottom is dropped, the slide device 78 is moved downward immediately before that. Since the stopper device 75 and the first holding device 76 are moved downward, the first electronic component 2a from the bottom is forcibly moved downward, so that the first and second electronic components from the bottom are moved. Even if 2a and 2b interfere with each other due to mold burrs or the like, they can be reliably separated and supplied to the measurement unit. Further, since the first electronic component 2a from the bottom is only held and moved in the supply direction and is not moved in the direction orthogonal to the supply direction, the burrs may interfere with each other, or the burrs may interfere with each other. Even if the electronic parts overlap with each other, the mold part is not damaged.

Further, according to the present invention, the pair of sandwiching pieces 108, 109 of the first holding device 76 are movably supported by the first supporting device 79 in the directions of approaching and separating from each other, and the pair of sandwiching pieces 108, 109 are supported. 109 tension coil spring 11
3, the pair of holding pieces 133 and 134 of the second holding device 77 are movably supported by the second support device 80 so as to move toward and away from each other, and the tension coil spring 137. Since the first electronic component 2a and the second electronic component 2b from the bottom supplied into the passage 33 are displaced in the thickness direction due to a device jam or the like, the respective electronic components are urged toward each other. The 2a and 2b are held at that position and are not moved in the thickness direction. Therefore, the first and second holding devices 7
Even when the electronic components 2a and 2b are sandwiched by 6 and 77, the mold portion is not damaged.
