The present invention relates to an automatic tube feeding device of a handler for sequentially supplying a tube containing a device to a loading unit in a handler for inspecting and classifying a manufactured device in a manufacturing process.

In general, a handler for inspecting and classifying a device manufactured in a manufacturing process includes a stacking unit for stacking tubes into which a device is inserted, a transporting unit for sequentially transporting the tubes loaded in the stacking unit to a supply unit one by one, and being transported by the transporting unit. A supply unit for supplying a device to the tester unit, a head unit for transferring the device supplied to the supply unit to the tester unit, and a classification unit for classifying the tested device as a delivery track. It is comprised by the sending part which sends out the device classified by the said sorting part.

Conventionally, in order to supply the tube into which the device is inserted from the handler configured as described above to the supply portion, as shown in FIGS. The timing belt 2 with the 2a is rotatably installed by the motor 3, and the timing belt 2 with the recess 2a is rotatably installed by the motor 3, When the tube 4 into which the device is inserted is inserted and power is applied to the motor 3, the driving gear 5 rotated by the motor 3 is driven by the pulley shaft 6 and the driven gear 7 fixed thereto. Since the tube 4 fitted on the recess 2a of the timing belt 2 is sequentially aligned with the supply rail 1 one by one, the devices in the tube 4 are fed by the supply rail 1 by their own weight. Is transferred to). At this time, the upper part of the tube 4 is closed by the stopper 8, while the lower part is open for discharging the device, and the stopper which controls the exit of the device in the tube 4 which has been transferred to the inlet side of the supply rail 1. The plate 9 is provided to be movable up and down, so that the device can be supplied while being lowered only when the transfer of the tube 4 is completed.

On the other hand, the drive control of the motor 3 which moves the timing belt 2 is another tube in which the device is inserted by rotating the motor 3 when the sensor 10 installed at the outlet side of the tube 4 does not detect the device. By matching with the supply rail (1), the continuous operation is possible. However, such a conventional device has a small number of indentations 2a for inserting the tube 4 on the timing belt 2, which requires the operator to insert the tube frequently, as well as the tube 4 being transferred in an inclined state. There has been a problem that the device exits to the exit side and the workability is lowered.

The present invention has been made to solve such a problem in the prior art, while placing a large amount of tubes at a time in the stacker and at the same time horizontally moving the tube into which the device is inserted and tilt the device at a certain angle in a straight line with the supply rail The purpose is to make it available.

According to an aspect of the present invention for achieving the above object, the stacker is installed on the base to stack a plurality of tubes, and the yaw is provided so as to be horizontally movable in the vicinity of the stacker to supply the tubes one by one sequentially The automatic tube feeder of the handler is composed of a pusher having a fault, a tube supplied by the pusher, a housing rotatably installed in the housing so as to be inclined with the supply rail, and a rotation means for rotating the swing block at an angle. Is provided.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 3 and 4 of the accompanying drawings.

FIG. 3 is a side view of the present invention, and FIG. 4 is a plan view of FIG. 3, wherein a pair of stackers 13 for mounting the tube 12 on one side of the base 11 installed in the loading part of the handler face each other. On one side between the stacker 13 is provided with a pusher 14 for supplying one by one tube 12 loaded in the stacker 13 in order to be retractable by the cylinder (15) At this time, the pusher 14 is formed with a recess 14a so that the tube does not flow in the pusher when the tube 12 is transferred.

The device inserted in the tube 12 is inclined at the same angle with the supply rail 16 while supporting the tube 12 which has been horizontally transferred to the inlet of the supply rail 16 installed to be inclined at an angle. A swing block 17 is pivotally coupled to the housing 18 so as to be transferred to the tester part, and one side of the housing 18 has the swing block 17 in line with the supply rail 16. Rotating means is installed to rotate.

As the rotation means, a step motor may be installed in the housing 18 to rotate the shaft 19 coupled to the swing block 17 at an angle, but in one embodiment of the present invention, the cylinder 20 is mounted on the base 11. The hinge and the lever 21 is coupled between the cylinder rod and the shaft l9 exposed to one side of the housing 18 so that the swing block 17 rotates as the cylinder 20 moves forward and back a predetermined distance. In this case, since the connecting portion of the cylinder rod and the lever 21 is circular motion, the base 20 should be rotatably installed.

On the other hand, a cylinder 22 is provided to push the tube 12 conveyed by the pusher 14 into the swing block 17 in a line with the supply rail 16. When located near the rear end of the tube.

In addition, the inner side of each stacker 13 is supplied with a pusher 14 at the bottommost tube 12 and collides with the tube 12 inserted in the stacker 13 at the time of restoration. The cylinder 24 to which the lifting rod 23 for preventing is installed is provided, and the guide rail 25 for stably conveying the tube 12 is fixed to the base 11 inside.

In addition, the cylinder 27 having the clamp 26 coupled to the swing block 17 is fixed by the mounting plate 28, and on one side of the mounting plate 28, the vibrator repeatedly lifting and lowering according to the operation of the solenoid 29. 30 is installed and the sensor 31 for detecting the transfer of the device is installed at the inlet side of the supply rail 16, in which the repetitive lifting movement in accordance with the operation of the solenoid 29 on one side of the mounting plate 28 The reason why the oscillator 30 is installed is that if the transfer of the device is not detected by the sensor 31 installed at the inlet side of the supply rail 16, the upper part of the tube 12 is repeatedly beaten and remains in the tube 12. To supply the devices that may be present.

Referring to the effects of the present invention configured as described above are as follows.

First, when the tube 12 into which the device manufactured in the manufacturing process is inserted is placed between the stackers 13, the tube 12 positioned at the lowermost end is inserted into the recesses 14a of the pusher 14. In this state, when the cylinder l5 is operated to push the pusher 14 toward the supply rail 16 and to be in line with the swing block 17, the cylinder 22 positioned at the rear end of the tube 12 is operated. Thus, the tube 12 positioned on the recessed groove 14a is pushed between the swing block 17 and the clamp 26 and the cylinder 22 is reduced to the original state. As such, when the tube 12 is inserted between the swing block 17 and the clamp 26, a separate proximity sensor (not shown) detects this to operate the cylinder 27 fixed to the mounting plate 28. The clamp 26 is lowered to support one side (the feeding side of the device) of the tube 12. Then, when the cylinder 20 hinged to the base 11 is operated to push the lever 21, one end of the lever 21 and the fixed shaft 19 are rotated in the clockwise direction in the drawing, and (b) of FIG. Since the swing block l7 fixed to the shaft 19 is connected to the inlet at the same inclination angle with the supply rail 16, the device inserted in the tube 12 is removed from the supply rail 16 by its own weight. Through the tester part is supplied at once.

In the state in which the device is transferred to the tester unit by the operation as described above, the sensor 31 installed at the inlet side of the supply rail 16 detects this. If the transfer of the device is not detected, the lead vent of the device is detected. The vibrator 30 is repeatedly raised and lowered several times to energize the solenoid 29 fixed to the mounting plate 28 to transfer a device that may be caught in the tube 12. If the sensor 31 does not detect the device transfer even by such an operation, the device supply in the tube 12 is completed.

On the other hand, the cylinder l5 for moving the pusher 14 is reduced to the initial state when the tube 12 is rotated by the swing block 17 and pushes the lowermost tube positioned between the stackers 13. It is placed on the inlet groove (l4a) of the, this time the cylinder (24) installed inward of the stacker 13 is operated to prevent the pusher 14 is restored and collide with the lowermost tube 12 After the tube 12 is raised, the tube 12 is positioned in the recessed groove 14a as the pusher 14 is restored and then lowered. After the pusher 14 is returned to the initial state and the device inserted into the tube 12 is transferred to the tester part, the sensor 31 detects this and activates the cylinder 20 to pull the lever 2l, thereby swinging the swing. The block 17 is separated at the inlet side of the supply rail 16 to form a horizontal state with the base 11. When the cycle is completed and the empty tube is level with the base as described above, the cylinder 15 for transporting the pusher 14 is operated to move the new tube 12, which is the device, in the straight line of the supply rail l6. Since the end of the pusher 14 is dropped, the empty tube 12 mounted between the swivel block 17 and the guide rail 25 is dropped into a separate stacking box (not shown), and at the same time, the tube 12 is loaded with the device. ) Is located at the inlet side of the swing block 17 is to enable continuous operation.

As described above, the device of the present invention is rotated inclined to the supply rail 16 by sequentially moving horizontally in a state in which the device is loaded with a large number of tubes (12) in the stacker (l3) at a time, so that unmanned operation for a long time This will not only improve productivity, but also prevent the device from exiting the outlet side of the tube.
