90 is attached, giving the shutter 91 the opposite movement of the shutter 79, and
Only when the electromagnet 85 is de-magnetized, the shutter 9 and the shutter 91 approach from both sides and enclose the suction pin 19, thereby reliably removing the defective square plate-shaped electronic component 13 at the tip of the suction pin 19.

Next, referring to FIG. 13, the positioning section 23 will be explained. The rectangular plate-shaped electronic component 13 attracted to the tip of the suction pin 19 is correctly positioned at the center of the suction pin 19 by the operation of the four pairs of positioning levers 92. Each positioning lever 92 has four pairs of shafts 9.

Next, the insertion portion 25 will be explained with reference to FIGS. 14 and 15. The shipping tape 24 has its feeding hole 1.
A pulley 104 that performs an intermittent indexing operation and has a pin 103 that engages with a pin 103 sequentially sends the sheets to the insertion section 25. In the insertion part 25, the square plate-shaped electronic component 13, which has been accurately positioned by the positioning part 23 at the tip of the suction pin 19, matches the square hole 105 provided in the shipping tape 24, and is inserted by the downward movement of the suction pin 19. An action is taken. Here, since the suction pin 19 is always in a vacuum state, it is necessary to separate the square plate-shaped electronic component 13 from the suction pin 19, so the shutter 106 is used.

That is, when the suction pin 19 descends, the shutter 106 moves to the suction pin 19 side, covers the square plate-shaped electronic component 13, and releases it when the suction pin 19 moves upward. Furthermore, in that state, the pulley 104 is 1
In order to be fed, the square plate-shaped electronic component 13 is smoothly guided into the fixed guide 107 and the fixed lid 108. Pulley 104 is held by shaft 109.

6b, cam 113 and spring 1 via cam follower 110, lever 111, and cam follower 112
14. The shaft 106a is a bearing 115
It is maintained by

Next, the intermittent drive section 26 of the shipping tape 24 will be explained in detail with reference to FIGS. 16 and 17. In order to prevent tooth loss in the square plate-shaped electronic component 13 in the shipping tape 24, the square hole 105 of the shipping tape 24 corresponds to the position removed by the two pairs of defect ejecting parts 22, 22'. When this occurs, it is necessary to instantaneously stop the pulley 104 by one indexing operation at extremely high speed.
This is achieved with the configuration shown in the figure.

First, the shaft 109 that holds the pulley 104 has a bearing 1
It is rotatably held in a box 117 via a gear 16 and connected to an indexing shaft 120 via a gear 118 and a gear 119. The gear 121 is for eliminating back clearance. The indexing shaft 120 is rotatably connected to the box 117 by a ball bearing 122 and a metal fitting 123. The indexing shaft 120 is provided with a ratchet wheel 124, which is given indexing motion by a cam 129 via a ratchet 125, a pin 126, a lever 127, and a cam follower 128. A ball bearing 130, a collar 131, and a lever 127 are rotatably held on the indexing shaft 120. Here, in order to improve the indexing accuracy and to prevent the ratchet wheel 124 and the ratchet 125 from coming off during high-speed operation, a cam follower 135 provided on a presser lever 134 that is swung by a cam 132 and a cam follower 133 is used to control the indexing. To restrict the ratchet 125 toward the center during movement. The lever 134 is rotatably attached to the box 117 via a ball bearing 135 and a pin 136. Furthermore, indexing axis 1
The notch lever 137 is driven into the tooth shaft 119 provided on the indexing shaft 120 so that the notch lever 137 does not move during indexing. The notch lever 137 is driven by a cam 139 via a cam follower 138.

The notch lever 137 has a ball bearing 140 and a pin 14.
1 and is rotatably held in a box 117. Next, the camshaft 142 that is in charge of driving is bearing 1
43, and is rotatably attached to the box 117 via a metal fitting 144. The drive pulley 145 rotates the camshaft 142 and is attached to the camshaft 142 via a distance piece 146.
It is driven by a timing belt 147.

Spring 148 is held by pin 149 and feeds ratchet 125. Spring 150 is held by pin 151 and drives presser lever 134. Spring 152 drives notch lever 137. All operations here are spring operations, and the shipping tape 24
If the resistance increases due to clogging or the like within the fixed guide 107 and the fixed lid 108, the feeding function will not work due to the escape of the spring, and the product will not be damaged. Next, when stopping the indexing operation momentarily, the electromagnet 1
53 is magnetized to stop the swinging movement of the lever 127, thereby stopping the indexing movement. The metal fitting 154 is for holding the electromagnet 153.

Next, the heat seal portion 27 will be explained with reference to FIG.

Square plate-shaped electronic component 1 contained in shipping tape 24
3, a thermocompression bonding tape 156 is supplied from an upper reel 157, guided onto the shipping tape 24 via a tape guide 158, and thermocompression bonded from above with an iron 159. In this case, since the iron 159 is pressurized by the electromagnet 163 through the plate 160, shaft 161, and iron plate 162 only when the shipping tape 24 is stopped, problems such as meandering and warping of the thermocompression tape 156 are eliminated.

A heater 164 and a temperature sensor 165 are embedded within the iron 159 to keep the temperature of the iron 159 constant.

Next, FIG. 19 shows a flowchart of the number setting system. In other words, only non-defective products are counted, and when the initial amount (number of items) is completed, the inspection disk 18
Stop the rotation of and feed only the pulley 104 alone.
During this time, the shipping tape 24 is emptied for a certain length, and the inspection disk 18 is rotated again to fill it with non-defective products. The above-mentioned blank portion of a certain length is processed as a leader tape section in the electronic component mounting machine. Here, the number of tapes and the length of the leader tape can be set arbitrarily.

As described above, according to this embodiment, chip-shaped electronic components are reliably fed one by one, and during transportation by the numerous vacuum suction pins of the inspection disk with an elevating function,
By setting up two inspection processes, in order to perform suction, front/back discrimination, characteristic inspection, and defect ejection twice each, as well as positioning and insertion at the same time,
Mixing of defective products with non-defective products can be almost completely prevented.

Effects of the Invention As described above, the present invention provides a ball feeder, a linear feeder, a supply section that reliably separates and supplies one item at a time, an inspection disk with an elevating function and an intermittent indexing mechanism, which is equipped with a large number of vacuum suction pins, and an inspection disk with an intermittent indexing mechanism. By providing two parts in the conveyance process for front and back discrimination, characteristic inspection, defect ejection and positioning parts, an insertion part, an intermittent drive device, a heat seal part, and a number setting function and a leader tape function, It is now possible to sort out defective products twice, almost completely preventing defective products from getting mixed in with non-defective products, and compared to conventional methods, all the work from picking up the parts to inserting them can be done with just the lifting and lowering and indexing functions of the inspection disk. This makes it possible to produce rectangular plate-shaped electronic component tape-packed products having a predetermined number of pieces and a leader tape length at extremely high speed and with extremely high efficiency.
