CONSTITUTION:A pole 2 on which an IC 3 is slid from a magazine 5, a stopper support rod 17 which is provided in parallel with the pole 2 and supports a stopper 8a positioning the IC 3, support rods 13a and 13b which have a lead detecting sensor 10 detecting the leads of the IC 3 and a probe detecting sensor 11 detecting a probe 4 corresponding to the lead and is moved in parallel with the pole 2 and motors 14 and 15 for moving the stopper support rod 17 and the support rods 13a and 13b in parallel with the pole 2 are provided. For instance, the probe 4 of the measuring part of the testing apparatus and the lead of the IC 3 are detected by the sensors 11 and 10 and the IC positioning mechanism is operated and automatic adjustment is performed so as to have the lead of the IC 3 and the probe 4 always agree with each other.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a handler for loading and unloading ICs on and from test equipment in IC characteristic tests.

[Conventional technology]

FIG. 2 is a side view of a conventional handler.

Conventionally, this type of handler is an IC3, as shown in the same figure.
A stopper 8 that stops the magazine 5, which is a supply unit for sequentially feeding the balls 2, and the IC3 falling from the magazine 5 at the position where the lead and the measuring needle 4 match, accommodates the magazine 5, and attaches the stopper 8 to its tip. It is composed of a carrier head 1 that holds a support rod, and a bracket 6 to which an adjusting screw for adjusting the height position of the carrier head 8 is attached.

The operation of this handler is as follows: First, from the magazine 5, the IC
3, rotate the ball 2 in the direction of arrow B, and press the stopper 8.
Stops receiving IC3. At this time, the lead of the IC 3 and the measuring needle 4 coincide and come into contact. Next, the primary signal is sent from the main body of the test device to the signal IC3, and the response signal is sent from the IC3.
A test device determines whether the characteristics of IC3 are good or bad. Next, when the test is finished, the stopper 8 rotates in the direction of arrow A, and the IC
3 is repeated, and all the ICs accommodated in the magazine are inspected.

[Problem to be solved by the invention]

In the conventional handler described above, when changing the type of IC to be inspected or before carrying out an inspection,
The positions of the lead C3 and the measuring needle 4 must match each other. Therefore, by turning the adjustment screw 9 attached to the bracket 6, the adjustment screw 9 can be moved up and down in the support part 7, which is a nut, and the carrier head 1 and the stopper 8 can be moved up and down.
was adjusting the position. However, this adjustment work not only requires a large amount of man-hours, but also has the drawback that accurate position adjustment cannot be expected because it is judged by the human eye.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate such drawbacks, to provide a handler that does not require initial IC positioning adjustment work and can accurately position the IC.

[Means to solve the problem]

The handler of the present invention includes a ball that slides and moves an IC from a magazine, a stopper support bar that is arranged parallel to the ball and holds a stop that positions the IC, and a stopper support bar that moves parallel to the ball and holds the IC.
a support rod to which a lead detection sensor for detecting a lead and a measuring needle detection sensor for detecting a measuring needle corresponding to the lead are attached at one end; and for moving the stopper support rod and the support rod parallel to the ball. It has a motor.

〔Example〕

Next, the present invention will be explained without reference to the drawings. The second figure is a side view of a handler showing one embodiment of the present invention. This handler, as shown in the figure,
Lead position detection sensor 0 that detects the lead position at the final end of 3 and a first support jFIJ 13 that holds it.
a, a second support rod 1 to which a measuring needle sensor 1 for detecting the measuring needle 4 corresponding to the final end lead and a lower limit sump 12 for detecting the lower limit position of the stopper 8a are attached.
3b, an arm 13c that joins and connects the first support rod 13a and the second support rod 13b, a second motor 15 that slightly moves the arm 13c up and down, and a stopper 8a and a stopper holder that holds the stopper 8a. A first motor 14 is provided to slightly move the carrier head 1a including the rod 17 up and down.

Further, the first motor 14 is attached to the bracket 6a, and one end of the feed screw directly connected to the first motor 14 is fitted into a nut of the receiver portion 7a. Further, the second motor 15 is attached to a stay 16 projecting from the bracket 6a, and one end of a feed swash directly connected to the second motor 15 meshes with a nut at the other end of the arm 13c.

Next, the stopper position adjustment operation in this handler will be explained. First, the second motor 15 rotates, and the first and second support rods 3a attached to the arm 13c,
3b rises, the measuring needle position detection sensor 11 attached to the first support rod detects the measuring needle 4 at the final end of the inspection device, the second motor 15 stops rotating, and the first support rod 1
3a stops rising. Next, start the first I from magazine 5.
Slide down C3 and stop the receiver with stopper 8a.

Next, the first motor 14 rotates, the stopper support rod is raised, and the IC 3 is raised by the stopper 8. Next, I.C.
When the final end of the lead 3 is detected by the lead position detection sensor 10, the first motor 14 stops rotating and the stopper 8
a stops at that position and is positioned. Further, the lower limit sensor 12 detects the lowest limit of the position of the stopper 8a, and detects abnormal operation of the handler.

By installing such an automatic sequence adjustment mechanism, positioning adjustments can be made within a few minutes even if the type of IC is changed.

〔Effect of the invention〕

As explained above, in addition to the conventional handler, the present invention provides λ! of the measuring section of the inspection device. 11 The fixed hand and the IC lead are detected by a sensor, and the IC to which these sensors are attached
By activating the positioning mechanism and automatically adjusting the IC lead and measuring needle so that they always match, a handler that does not require initial IC positioning work and can accurately position the IC can be obtained. It has the effect of being
