This paper proposes the automatic supply of empty sleeves of handlers to transfer empty sleeves loaded on the loading section to the discharge track for inserting devices from the discharge section of the handler for inspecting and classifying devices manufactured in the manufacturing process into the empty sleeves. Relates to a device.

In general, the handler for inspecting and classifying a device manufactured in a manufacturing process is as shown in FIG. 1, and the handler is classified into a larger size in order to stack the sleeve into which the device is inserted. Transfer unit (2) for feeding the feed unit to the supply unit, supply unit (3) for supplying the device transferred to the transfer unit to the tester unit, the head unit (4) for transferring the device supplied from the supply unit to the tester unit, and the discharged track ( And a sending section 7 for sending out devices classified by the sorting section 6.

Conventionally, a bin sleeve is installed on one side of the delivery unit configured as described above, and a transport block operated by a cylinder is installed below the bin, so that one bin sleeve loaded on the stack is lowered to As it is located on one side, the cylinder is operated to transfer the empty sleeve to the delivery track side.

Therefore, when the bin sleeve is positioned on one side of the transport block to transport the bin sleeve loaded on the loading unit to the lower side of the delivery track, the cylinder is operated to transfer the transport block to the delivery track side.

As the transfer block transfers the empty sleeve to the delivery track, the fixed block installed below the delivery track is lowered by the cylinder to fix the empty sleeve.

However, such a conventional apparatus has no means for exactly matching the empty sleeve with the delivery track, and is designed to be transported according to the stroke distance of the transport block, so that the inlet of the empty sleeve and the delivery outlet of the delivery track cannot be exactly matched. As a result of frequent jams, the bin sleeves were moved to the delivery track by simply pushing them, which made it impossible to transport the bin sleeves.

In addition, when testing a device with a width of 300m: 1, if you want to test a device with a different width, the transfer block had to be replaced.

This paper has been devised in view of the above-described drawbacks of the prior art, and has an object of enabling the bean sleeve to be stably positioned and supported at the bottom of the delivery track.

According to the present invention for achieving the above object, a pair of mounting plates are installed on the main body to correspond to each other, and a guide piece fixed to the mounting plate is provided with a transfer piece for fixing the cylinder, and the finger is fixed below the cylinder. To fix the finger block and to fasten each conveying piece to the belt wound on the pulley, and to connect the pulley to the power transmission shaft so that the motor power can be transmitted to the conveying piece through the belt. An automatic feeder is provided.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 2 to 6 of the accompanying drawings.

FIG. 3 is a perspective view of the present invention, and FIG. 4 is an exploded perspective view of the main part. In the present case installed directly below the delivery track 5, a pair of mounting plates 9a and 9b are mutually connected to the main body of the handler. The conveying piece 12 for fixing the cylinder 11 is coupled to the guide side 10 which is installed correspondingly and fixed to the mounting plates 9a and 9b, and below the cylinder 11 there is an empty sleeve ( The finger 14 for holding and releasing 13 and the push pin 15 are fixed to the finger block 17 which is elastically fixed with the spring 16.

The finger 14 actuated by the cylinder 11 is elastically installed with the spring 20 so that the pair of tong pieces 18 can be rotated about the pin 19 as shown in FIG. In the upper part of the piece 18, the bearing 22 which presses the tong piece 18 by the piston 21 is provided.

A pair of pulleys 24, on which the belt 23 is wound, is rotatably installed on the mounting plates 9a and 9b, and the transfer piece 12 is fixed to the pulley 24 by the fixing plate 25. The pulley 24 on one side is interconnected to the power transmission side 26 so that they are interlocked with each other as the step motor 27 rotates, and the feed amount of the conveying piece 12 is not included in the program of the controller (not shown). It can be easily adjusted by.

In addition, the movable piece 28 having the engaging projection 28a can be rotated about the axis 29 directly below the fixed installation plate 9b, that is, below the delivery track 5, as shown in FIG. A guide block 31 having a recessed groove 31a is coupled to the cylinder 30 and provided on the other side of the mounting plate 9a so as to be able to move back and forth by a cylinder (not shown).

The operational effects of the present proposal thus constructed are as follows.

First, a description will be given from a state in which the first bean sleeve 13 is placed on the movable 28 to insert a device (not shown) to be sent to the delivery track 5.

In this state, the recessed groove formed below the bin sleeve 13 is inserted into the engaging projection 28a formed on the movable piece 28 to position the device. As the cylinder detects this, the cylinder for driving the movable piece 28 and the guide block 31 is operated to raise the movable piece 28 and pull the guide block 31 at the same time. It falls to a loading box (not shown).

As the sleeve falls from the delivery track 5 as described above, the finger 14 is transferred to the loading side to grip the empty sleeve 13 loaded on the loading portion, where one empty sleeve is installed. It is a state waiting on one side of (9a) (9b).

When the pulley 24 is rotated by the step motor 27 in this state, the conveying piece 12 fixed to the belt 23 is conveyed to the empty sleeve side, that is, the right side in the drawing.

After that, the cylinder 11 is operated to lower the finger block 17 so that the bin sleeve 13 is positioned between the tong pieces 18 so that the piston 22 is lowered by a separate pneumatic means to lower the bearing 22. Since it is pressed, the tong piece 18 is crimped inward while pressing the spring 20 to grip the empty sleeve 13.

As described above, when the tong piece 18 of the finger 14 grips the empty sleeve 13, the cylinder 11 is operated to raise the finger block 17 to the initial state and at the same time the step motor 27 The reverse rotation rotates the conveyance piece 12 directly below the delivery track 5 without a sleeve.

Then, when the cylinder 11 is lowered and the empty sleeve 13 coincides with the outlet of the delivery track 5, the cylinder 30 for raising the movable piece 28 and the cylinder for advancing the guide block 31 At the same time, the completion of positioning of the bin sleeve 13 is completed. At this time, the engaging piece 28a is formed in the movable piece 28 so that the outlet of the delivery track 5 and the inlet of the bin sleeve 13 are formed. Exactly matches

In this way, when the bin sleeve 13 completes the delivery track 5 and the positioning, the supply of air that has been supplied to retract the forceps 18 of the finger 14 is stopped. The sebum state of 13) is released and restored to the initial state by the spring 20.

What has been described so far has described one cycle for supplying and positioning one bean sleeve 13 to contain the device sent out from the delivery track 5, and this operation is carried out continuously.

As described above, the device of the present invention installs the fingers 14 on the mounting plates 9a and 9b so as to be transported by the pulley 24, so that the empty sleeve 13 is always directly under the delivery track 5. The binsley supplied by installing the movable piece 28 having the engaging projection 28a and the guide block 31 having the recessed groove 31a in a straight line of the delivery track 5 can be supplied to the room accurately. Since the eve 13 can be accurately positioned, it has an effect that can prevent the occurrence of shock during operation.
