Description

TECHNICAL FIELD The present invention relates to a device for loading electronic components such as chip resistors and leadless diodes into a large number of component storage portions in a magazine, one by one.

[Conventional technology]

Generally, magazines as shown in FIGS. 11 and 12 are used for packaging electronic parts having terminals at both ends such as chip resistors and leadless diodes.

This magazine 1 includes a long tape 2 made of a thin sheet of synthetic resin, a large number of component storage parts 3, and the long tape 2
To form recesses by vacuum forming at appropriate intervals in the longitudinal direction of
After electronic components 4 are loaded one by one in each of the component storage portions 3, a cover tape 5 is attached to the upper surface of the long tape 2 by heat welding or the like to hermetically pack (this is called taping). It was configured to do.

And conventionally, the long tape 2 in this magazine 1
An apparatus as shown in FIG. 13 is used to load the electronic components 4 one by one into each of the component storage sections 3 of FIG.

That is, in this conventional loading device, the supply section A of the electronic component 4, the inspection section B of the electronic component 4, and the taping section C are arranged in a horizontal row, and the supply section A and the inspection section are provided above the supply section A. A first suction collet D that reciprocates horizontally with respect to B;
A second suction collet E that horizontally reciprocates between the inspection unit B and the taping unit C is provided, and when the first suction collet D is at the position of the supply unit A, the second suction collet D descends and is located directly below. When the electronic components 4 sequentially sent by a parts feeder or the like (not shown) are adsorbed, the first adsorption collet D moves up and then moves horizontally to the inspection unit B and descends, and then the electrodes in the inspection unit B are moved. Electronic component 4 with pieces b1 and b2
Both terminals 4a, 4b in the electronic component 4 are both electrode pieces b.
The first suction collet D releases the suction of the electronic component 4 and returns to the original position while being sandwiched so as to come into contact with each of 1, 1 and 2, while in the inspection unit B, the electronic component 4 is energized. The performance is inspected, and when the electronic component 4 is a defective product, it is excluded by releasing the sandwiching, and when the electronic component 4 is a good product, the electronic component 4 is sucked by the second suction collet E. . Then, the second suction collet E moves horizontally to the position of the taping portion C that has moved upward, and then moves downward to release suction, and the electronic components 4 are loaded into the component storage portions 3 of the magazine 1. It was configured to repeat the operation.

[Problems to be Solved by the Invention]

However, this conventional loading device uses two suction collets, and the two suction collets are separately reciprocated in the horizontal direction, and are vertically moved at both ends of the reciprocating movement. Since the structure for moving is extremely complicated, the device becomes significantly large and expensive, and the total moving distance including horizontal reciprocating movement of both suction collets and vertical movement at both ends is extremely high. However, since it takes a long time to move the cartridge and therefore it takes a long time to move the cartridge, the loading speed of the magazine is slow, which is rather inefficient.

In addition, both suction collets have to be lifted in a state in which the electronic parts are sucked in the supplying part and the inspecting part, and there is a problem in that handling errors of the electronic parts frequently occur during the lifting.

It is an object of the present invention to provide a loading device that solves the problems of this conventional loading device.

[Means for solving the problem]

To achieve this object, the present invention has a suction collet that moves up and down at the upper part of a magazine with a component storage part that is intermittently transferred, and the suction collet is provided between the suction collet and the magazine in a raised position. A table plate having a guide hole passing therethrough is provided movably in a substantially horizontal direction. The guide hole in the table plate is located at a position below the suction collet, and the guide hole is located at a position removed from below the suction collet. While providing a moving mechanism adapted to take a position, a component supply mechanism for sequentially supplying electronic components to a portion below the suction collet is disposed on the upper surface side of the table plate, and further, the lower surface of the table plate. On the side, a pair of inspection electrode pieces that are in contact with the electronic component and both terminals and are energized to the electronic component, and a defective electronic component from between the inspection electrode pieces. And the configuration of disposing the exclusion means as excluding towards.

[Operation and effect of invention]

In this configuration, when the electronic component is supplied to the portion below the suction collet by the component supply mechanism, the suction collet descends to suck the electronic component in the lower portion, and then the table plate Horizontally moves so that the guide hole in is located below the suction collet.

Then, the suction collet descends so as to pass through the guide hole while adsorbing the electronic component, and on the lower surface side of the table plate, to both terminals of the electronic component adsorbed by the suction collet, The inspection electrode pieces come into contact with each other and are energized to inspect the performance of the electronic component.

In this inspection, if the electronic component is a defective product, the defective electronic component is laterally excluded from the suction collet by the excluding means, and if the electronic component is a good product, the suction collet is After the electronic components are further sucked down toward the magazine, the electronic components are loaded in the magazine by releasing the suction.

When this is finished and the suction collet rises to the original position, the table plate moves horizontally so that the guide hole in the table plate comes off from below the suction collet, and then the component supply mechanism moves the next electronic component. While supplying to the portion below the suction collet, the magazine is sequentially transferred by the component supply mechanism by repeating the operation that the next component storage section in the magazine is intermittently transferred so as to come to the portion below the suction collet. While checking the performance of the sent electronic components, only the good electronic components are loaded into each component storage section of the magazine one by one.

Therefore, according to the present invention, the suction collet is only required to move up and down, as in the prior art, two suction collets are used, and both suction collets are horizontally reciprocated, and Since it is not necessary to move up and down at both ends of the reciprocating motion, the structure for moving the suction collet becomes extremely simple, the device can be downsized, and it can be provided at low cost. By significantly shortening the moving distance, the time required to load one electronic component can be shortened. In other words, the speed of loading the electronic component into the magazine can be increased, and the efficiency can be significantly improved. Have.

In addition, the suction collet in the present invention is loaded in the magazine by the downward movement in the state where the electronic component is sucked, and does not lift the electronic component in the sucked state unlike the conventional suction collet. It also has the effect of reliably reducing handling mistakes of parts.
