Directional slit! 6b, and the recess 16
By raising the lifting block 16 after feeding the cylindrical main body 1a of the electronic component 1 into the slit 16b, the two lead wires 1b and ]C are positioned within the slit 16b, and the electronic component 1 is rotated. It is possible to transport the material upward while preventing it from occurring.

The gripping block 18 connecting the cylinder 20 and the lifting block 16 has 1. Recess 16 of the lifting block 16
A gripping claw 18a is provided opposite to the gripping claw 18a, and the gripping claw 18a is rotated counterclockwise in FIG. The cylindrical main body portion 1a is gripped between the lift block 16 and the grip block 18 can be released by swinging in the opposite direction when the grip block 18 is lowered by the cylinder 20.

Roughly, as shown in FIG. 6, there are two screws located below the recess 16a of the lifting block 16 that grips the cylindrical main body 1a of the electronic component 1 and the gripping claw 18a of the gripping block 18. A determining means is provided for detecting the difference in length between the lead wire 1b and the IC and determining in which direction the electronic component 1 is supplied.

This discriminating means is equipped with a support lever 26 that is swingably supported by a pin 25 on the machine frame 14. In its natural state, this support lever 26 is biased by a spring 27 and rotated clockwise in FIG. , whose upper end portion is held in a position where it abuts against a bracket 28 attached to the machine frame 14. However, when the lift block 16 is located at the lower end position, it is rotated counterclockwise by the lift block 16 so that its upper end is separated from the bracket 28 by a predetermined distance.

At the upper end of the support lever 26, as shown in FIG.
The lead wires 1b and 1c can be captured inside each engagement groove 26a when the upper end of the support lever 26 is brought into contact with the bracket 28.

Further, a stopper portion 26b is formed on one side of the support lever 26, and when the support lever 26 is brought into contact with the bracket 28, the stopper portion 26b is connected to the lead wire 1b or 1c of the subsequent electronic component 1. It is possible to stop the advance by bringing it into contact with the On the other hand, when the upper end of the support lever 26 is separated from the bracket 28, the subsequent electronic component 1 is allowed to move forward and can be supplied into the recess 16a of the lifting block 16. .

Furthermore, the bracket 28 has each of the engagement grooves 26a.
A pair of detectors 29 are provided to detect the presence or absence of the lead wire 1b and IC captured within the electronic component 1, and a detector 30 is provided to detect the presence or absence of the electronic component 1 itself.

In the article delivery device 13 having the above configuration, when the lifting block 16 and the gripping block 18 are located at the lowering end position and the gripping claws 18a are open, the lifting block 16 located at the lowering end position supports the article delivery device 13.

The pair of lead wires 1b and IC that are raised as the lifting block 16 rises is captured in the engagement groove 26a, and the stopper portion 26b on one side of the support lever 26 is connected to the lead wire 1b of the subsequent electronic component 1. Alternatively, it is brought into contact with the IC to stop the electronic component 1 from entering.

The detector 29 provided on the bracket 28 is connected to each engagement groove 2.
The presence or absence of the lead wire 1b and IC captured in the lead wire 6a is detected, and as the lifting block 16 rises, each engagement groove 26a
By detecting which lead wire is pulled out first when the lead wire 1b and the IC are pulled out from inside,
Determine the orientation of electronic components.

Furthermore, when the chuck 12 of the second article conveying means 10 grips the cylindrical main body 1a of the electronic component 1, the cylinder 20 starts lowering the gripping block 18, and at this time, the cylindrical main body 1a is moved by the gripping claws 18a. The grip is released, and the grip block 18 and the lifting block 16 are lowered together. When both of them are at the lower end position, the grip claw 18a is in the open state, and the lifting block 16 is at the lower end position, so that the upper end of the support lever 26 is separated from the bracket 28, so that the subsequent electronic component 1 is advanced and supplied into the recess 16a of the lifting block 16.

2 are all open. The gripping cylinder 41 is provided above the article delivery device 13,
When the electronic component 1 is inserted between the released gripping block 36 and the fixed block 34 from the article delivery device 13, the gripping cylinder 41 operates to grip the cylindrical main body 1a of the electronic component 1 on the chuck 12. It is designed to let you do so.

Furthermore, in FIG. 1, the index table 11
Processing sections 45 to 47 are arranged around the index table 11 to perform various processing on the electronic component 1 held by the chuck 12 and having the lead wires 1b and 1c protruding outward in the radial direction. .50 to 52 are provided.

The processing section 45 next to the delivery section where the electronic component 1 is delivered from the article delivery device 13 is a press section, and in this press section 45, the lead wires 1b and Ic are pressed by a pair of flat press plates. By this, each lead wire 1

9 is housed in a storage box 60 provided at a lower position of the machine frame 14, and its both end surfaces are supported by both inner surfaces of the storage box 60, and the lower part of its outer peripheral surface is rotatably supported by a pair of rollers 61. are doing. And this mount tape supply reel 5
The backing tape 57 pulled upward from the tape 9 is supplied to the feed motor 63 through an idle pulley 62, reversed downward through an upper idle pulley 64, and then fed through a plurality of idle pulleys 65. It is supplied to the taping section 52.

On the other hand, an adhesive tape supply reel 66 on which the adhesive tape 58 is wound is provided above the machine frame 14, and the adhesive tape 58 pulled out from the adhesive tape supply reel 66 is fed to a plurality of idle pulleys 67. , and then superposed on the backing tape 57 at the taping portion 52.

The feeding motor 63 is configured to be able to feed out the mount tape 57 at a supply amount larger than the consumption amount of the mount tape 57 in the taping section 52, and thereby the mount tape 57 is fed out between the feeding motor 63 and the upper idle pulley 64. The paper tape 57 is extruded in a diagonally upward curve,
When the curved mount tape 57 comes into contact with a limit switch 68, the operation of the feed motor 63 is stopped.

Therefore, a predetermined amount of the backing tape 57 can be always held in a slack state between the feed motor 63 and the upper idle pulley 64, which creates unnecessary resistance when drawing the backing tape 57 into the taping section 52. Therefore, the backing tape 57 can be reliably supplied.

Further, the adhesive tape 58 passes through the taping part 52 and
The product tape 69 that is integrally attached is wound up by a take-up reel 70 provided on a different vertical plane from the backing tape 57 pulled upward from the backing tape supply reel 59 toward the idle pulley 64. There is. Therefore, the product tape 69 that has passed through the taping section 52 is twisted slightly in the lateral direction and then wound onto the take-up sole 70. The tape 69 is being wound up.

Further, in this embodiment, an interlayer paper reel 72 is provided above the take-up reel 70, and the product tape 6 is wound with the interlayer paper 73 pulled out from the interlayer paper reel 72 onto the take-up reel 70.
It is placed between 9 and 9.

However, as shown in FIG. 10, the taping portion 52 includes a pressure bonding member 77 that clamps the mount tape 57 and the adhesive tape 58 and presses them together with a fixing member 76 attached to the machine frame 14. This pressure bonding member 77 is attached to a movable bracket 79 that is moved forward and backward by a cylinder 78. In addition, at a position in front of the crimp member 77,
A heater 80 is provided to heat the mount tape 57 and adhesive tape 58.

The pressure bonding member 77 is made of metal, and an elastic body 81 is attached above the tip of the pressure bonding member 77, and the above-mentioned index table! By the rotation (2), the lead wires 1b and lc inserted between the backing tape 57 and the adhesive tape 58 from above can be held relatively softly between the elastic body 81 and the fixing member 76. .

Also, a position below the tip of the crimping member 77 that corresponds to the feed amount of one pitch of the backing tape 57 and the adhesive tape 58;
The fixing member 76 opposite thereto has relief parts 77a and 76a for the lead wire 1b and the IC, and the metal part of the crimping member 77 and the fixing member 76 connect the mount tape 57 and the adhesive tape 58. By firmly holding the parts, reliable adhesion can be achieved.

Further, the movable bracket 79 is provided with a product tape made of the mount tape 57 and the adhesive tape 58 at an intermediate position of the electronic component 1 which is pasted at regular intervals between the mount tape 57 and the adhesive tape 58. A bunch 82 is provided at 69 to form a bunch hole. Further, below the punch 82, a bunch hole detector 83 is provided at a distance corresponding to the feed amount of one pitch.

In the illustrated embodiment, the detector 83 is provided with a detection rod 85 having substantially the same diameter as the bunch hole and biased toward the product tape 69 by a spring 84, and a detection rod 85 provided at the right end of the detection rod 85. A proximity switch 86 is provided to detect when the rod 85 approaches by a predetermined amount or more.

Therefore, when the product tape 69 is advanced by exactly one pitch, the detection rod 85 is moved forward by the bunch 82.
However, if the product tape 69 is not advanced by exactly one pitch for some reason, the detection rod 85 will come into contact with the product tape 69 and move relative to the product tape 69. Since the sensor is moved toward the proximity switch 86, it is possible to warn of the abnormality.

Further, at a position below the bunch 82, a feed roller 87 is provided which is intermittently rotated by a predetermined rotation angle by a pulse motor (not shown). A feed pawl 87a is provided to match the punching hole and engage with the punching hole. Therefore, by rotating the feed roller 87 intermittently by a required rotation angle, the product tape 69 can be transported intermittently at a predetermined pitch. In addition,
An annular groove 88a is formed on the outer peripheral surface of the roller 88 that brings the product tape 69 into close contact with the feed roller 87 to avoid interference with the feed claw 87a.

In the taping portion 52 having the above configuration, when the movable bracket 79 is located at the right side retracted position in FIG. . In this state, when the lead wire 1b and IC of the electronic component 1 are inserted from above between the mount tape 57 and the adhesive tape 58 by rotation of the index table 11 and stopped, the movable bracket 79 moves forward. and the crimp member 77
The mount tape 57 and the adhesive tape 58 are held relatively softly between the elastic body 81 and the fixing member 76, and the mount tape 5
7 and the adhesive tape 58 to connect the lead wire 1b of the electronic component 1,
Hold lc.

When the mount tape 57 and the adhesive tape 58 hold the lead wires 1b and IC of the electronic component 1, the grip of the electronic component 1 by the chuck 12 is released by the release cylinder 40 (not shown), and the movable bracket 79 returns to its original right side. It is returned to the retreat position. When the feed roller 87 is intermittently driven to rotate by a required rotation angle, the product tape 69 is intermittently conveyed by a predetermined pitch and then stopped.

In this state, the movable bracket 79 is moved forward again and the above-described operation is repeated, but when the movable bracket 79 is moved forward, at the same time as the above-mentioned operation, the crimp member 77
The mount tape 57 and the adhesive tape 58 are firmly sandwiched between the portion below the elastic body 81 and the fixing member 76, and the mount tape 57 and the adhesive tape 58 are brought into close contact with each other.

At the same time, the bunch 82 punches a bunch hole in the product tape 69, and the detection rod 85 is inserted into the punch hole already punched by the bunch 82. If the product tape 69 is not inserted into the bunch hole, the product tape 69 has not been fed by a predetermined amount, and the proximity switch 86 will alert you to the abnormality.
