The test mechanism section includes a test means for performing tests and inspections, and a device handling means for loading and unloading IC devices on the test means.

[0003] In order to improve the efficiency of loading IC devices to be tested into this test equipment and unloading tested IC devices, magazines are widely used as jigs for storing IC devices. It is used. This magazine consists of a stick-shaped member that stores a large number of devices in a line, and devices are taken out and stored through an opening at one end of the magazine. Therefore, a magazine containing devices is installed in the loader section, an empty magazine is installed in the unloader section, and one device is removed from the magazine in the loader section.
After being separated and taken out one by one, sent to a test mechanism section, and subjected to a predetermined test, they are stored again in a magazine installed in an unloader section.

[0004] The operation of inserting and removing a device in a magazine is
Since using a pusher or other forced feeding means would complicate the structure, the device is generally configured to slide under its own weight. For example, in order to slide the device, a tilting chute is installed at a predetermined angle in order to slide the device, and a magazine tilting mechanism is also installed, and this magazine tilting mechanism tilts the magazine from a horizontal state at the same angle as the tilting chute. Then, the device is transported into the test mechanism section by sliding it under its own weight along this slope. Further, after the test is completed, the device is sent to the unloader part which is provided in an inclined state.

[0005]

[Problem to be Solved by the Invention] When a test is performed in the test mechanism section with the device tilted at the same angle as this tilted chute, the device must be positioned at a predetermined position during this sliding. Then, it can be mounted on the test means. However, in order to ensure ease and accuracy in positioning the device, it is preferable to position the device in a horizontal state. Further, depending on the type of test, it may be preferable to mount the device on the test means in a horizontal state from the viewpoint of inspection accuracy. In an inclined chute, it is necessary to provide a roof section above the runway in order to guide the device and hold it so that it does not deviate from the conveyance path, and a mechanism for guiding the device package part to this roof section. be. For this reason, the top of the device is covered, so even if the device is received from the tilted chute and transferred from the tilted state to the horizontal state, the device cannot be transferred after being placed in the horizontal state. However, there are disadvantages such as a complicated mechanism for taking out the device.

The present invention has been made in view of the above points, and its object is to easily take out the IC device when it is displaced from an inclined state to a horizontal state. An object of the present invention is to provide an IC device transfer apparatus as described above.

[0007]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a base member which is provided with side walls on the left and right sides of the sliding surface of an IC device that can be connected to a sliding chute of the IC device; a roof member openably and closably connected to the side wall of the base member to form a device housing portion;
It has an orienter member having an IC device insertion/removal section on one end thereof, and by attaching this orienter member to a rotating shaft, it can be moved up and down between a state where it is tilted at a predetermined angle and a state where it is horizontal. A biasing means is applied to the roof member in a direction to cover the base member, and
An extending portion is connected to the roof member toward the opposite side of the connecting portion to the side wall of the base member, and an elevating drive means is connected to the elongating portion, and the elevating drive means is configured to cause elevating and elevating of the orienter member. The roof member is characterized in that it is configured to have a displacement stroke corresponding to the angle and the opening/closing angle of the roof member.

[0008]

[Operation] By adopting such a configuration, the orienter member is placed in an inclined state, and an IC device that slides under its own weight along the inclined chute is housed in the device housing portion of the orienter member, and the elevating drive means It can be displaced to the horizontal state by activating the . Here, at the beginning of this elevating motion, the base portion and the roof portion are simultaneously lowered. After the base part is in a horizontal state, the roof part is rotated and the upper part of the base part is opened by continuing to operate the elevation driving means. Thereby, the device transported in an inclined state by the inclined chute can be displaced to a horizontal state, and the device can be transferred. Further, by holding the orienter member in a horizontal state, housing the device in the orienter member, and moving the orienter member upward and downward, the device can also be fed into the inclined chute.

[0009]

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, in FIG. 1, 1 is an inclined chute;
10 is a device transfer device, and the inclined chute 1 includes, for example, a DIP type I as shown in FIG.
The C device D is carried in from the magazine M by sliding under its own weight. The inclined chute 1 includes device individual separation means that includes a first locking pin 2 that engages with the most advanced device D and a second locking pin 3 that engages with the next device D. are provided, and each of these locking pins 2 and 3 is configured to be driven by cylinders 4 and 5, respectively. Therefore, first, the locking pin 2 is held in an operating state, that is, a state in which the device D is stopped, and the locking pin 3 is in a retracted state, that is, a state that allows the device D to pass. is supplied, and the most advanced device D is stopped by the action of the locking pin 2. Then, when the locking pin 3 is activated to lock the second device D and the locking pin 2 is released, one device D is separated and sent out from the inclined chute 1. After that, locking pin 2
When the device is activated and the locking pin 3 is retracted, the next device will move to the most advanced position.

[0011] In this manner, the devices D are separated one by one and sent out at the exit portion of the inclined chute 1, and the devices D thus sent out are transferred to the transfer device 10. This transfer device 10 is
As is clear from FIGS. 3 to 5, the orienter member 13 includes a base member 11 and a roof member 12. The base member 11 includes a bottom wall 11a, side walls 11b and 11c erected on the left and right sides of the bottom wall 11a, and side walls 11b and 11c.
It is composed of a sliding portion 11d consisting of a protrusion formed between 11c and a sliding portion 11d. By covering the side walls 11b and 11c, the roof member 12 forms a device housing portion 13a for receiving the device D between the side walls 11b and the base member 11, and also covers the left and right shoulders of the package portion P of the device D. Guide walls 12a, 12a for guiding are formed. Further, in order to position the device D at a predetermined position when the device D is housed in the device housing portion 13a, a stopper pin 14 that comes into contact with the device D protrudes from the sliding portion 11d of the base member 11. It is set up.

Here, the roof member 12 is the base member 11.
It is attached so that it can be opened and closed freely. For this purpose, a shaft mounting portion 15 is extended from the side wall 11b of the base member 11, and an extending portion 12b from the main body portion that covers the top of the base member 11 is formed on the roof member 12.
The extending portion 12b is provided with a shaft mounting portion 16, and the shaft mounting portions 15 of the base member 11 and the roof member 12 are provided with a shaft mounting portion 16.
, 16, a shaft 17 is inserted between them. by this,
The roof member 12 is rotatable about an axis 17. Further, the orienter member 13 is connected to the inclined chute 1 and can be moved up and down between an inclined state for receiving the device D and a horizontal state. That is, a rotation shaft 18 is attached to the outer surface of the side wall 11c of the base member 11, and the rotation shaft 18 is rotatably supported by a bearing member 20 mounted on a base 19. A spacer 21 is provided on the base 19 to stably hold the orienter member 13 in a horizontal state.

In order to move the orienter member 13 up and down, a cylinder 22 is provided as an up-and-down drive means. A piston rod 22a of this cylinder 22 is pivotally supported by an extending portion 12a of the roof member 12. Further, a spring 23 is provided between the base member 11 and the roof member 12 to constantly bias the roof member 12 to a state in which the top of the base member 11 is covered.

By operating the cylinder 22, the orienter member 13 is moved up and down, but the stroke of the cylinder 22 simply moves the orienter member 13 between the horizontal state and the inclined state. A stroke that not only allows the roof member 12 to be vertically displaced, but also rotates the roof member 12 against the biasing force of the spring 23 after the roof member 12 is displaced from the inclined state to the horizontal state, thereby displacing the roof member 12 to a substantially vertical state. It has the following. Further, a positioning member 24 is provided protruding from the base 19 in order to position the device D located in the device housing portion 13a when the orienter member 13 is displaced to a horizontal state. is a through hole 2 through which the positioning member 24 is inserted at the position where the sliding portion 11d is formed.
5 have been established.

The present embodiment is constructed as described above, and its operation will be explained next.

First, by tilting the magazine M, it is connected to the tilted chute 1, and the device D stored in the magazine M is fed toward the tilted chute 1. At this time, by extending the cylinder 22, the orienter member 13 is held in an inclined state connected to the inclined chute 1. At this time, the roof member 12 of the orienter member 13 is held in a closed state covering the upper part of the base member 11 by the action of the spring 23. Therefore, a device individual separation mechanism consisting of a pair of stopper pins 2 and 3 provided on the inclined chute 1 is operated to separate one device D fed into the inclined chute 1 and accommodate it in the orienter member 13. . As a result, the device D that has entered the orienter member 13 is
The stopper pin 14 slides along the sliding portion 11d.
It stops at the position where it touches. In this state, the cylinder 22
When the orienter member 13 is contracted, the entire orienter member 13 first rotates downward about its rotation axis 16, and this orienter member 13 is displaced to a horizontal state. As a result, the base member 11 comes into contact with the spacer 21, and the base member 11 stops rotating at this position. Moreover, at a position midway through the rotational movement of the orienter member 13,
Since the positioning member 24 is projected onto the sliding surface from the through hole 25 provided in the sliding portion 11d of the base member 11, when the orienter member 13 is in a horizontal state, the positioning member 24 and the stopper pin 14, the device D is positioned.

However, even after the base member 11 comes into contact with the spacer 21 in this way, the cylinder 22 continues to contract, so that the base member 11
After the roof member 12 has stopped in a horizontal position, the roof member 12 has a spring 2 centered on the connection between it and the base member 11.
It rotates against the urging force of 3. And this cylinder 2
2 is displaced to the stroke end position, the roof member 22
is in a substantially vertical state, and the upper part of the base member 11 is open. As a result, the device D housed in the base member 11 is taken out by an appropriate pick-and-place means, such as by vacuum suctioning the top surface of the package part P, and placed in a desired part such as the inspection and measurement mechanism part. You will be able to transfer it. Moreover, when the device D is taken out, the device D is in a horizontal state and is positioned almost accurately, so the device D is taken out by the pick-and-place means.
It is convenient for transferring to mechanical parts or other predetermined locations where inspections, measurements, etc. are performed.

As a result, until the orienter member 13 completes the upward and upward movement after receiving the device D from the inclined chute 1 and the orienter member 13 is reliably in a horizontal state, the roof member 12 keeps the device accommodating portion 13a Since the upper part of the orienter member 13 is kept covered, it is possible to reliably prevent inconveniences such as the device D falling off from the orienter member 13 when the device D is received and when the device D is raised and raised. Furthermore, since the single cylinder 22 is used to raise and lower the orienter member 13 and to open and close the roof member 12, the structure of the mechanism for operating the orienter member 13 is significantly simplified.

Contrary to the above, if this transferring device 10 is used, as shown in FIG. It is also possible to send it to 30. In this case, the elevation movement of the orienter member 13 by actuating the cylinder 22 is configured to displace it from a horizontal state to a downwardly inclined state. Further, in order to accurately position the base member 11 in this horizontal state, an appropriate regulating member 3 that comes into contact with the upper surface of the base member 11 is required.
1 may be provided. Then, by extending a cylinder (not shown) for elevating motion, the base member 11 is brought into contact with this regulating member 30 to hold it in a horizontal state, and furthermore, the extension stroke of this cylinder is extended from this position. By making the roof member 12 larger, the roof member 12 can be rotated about the shaft 17 to open the upper part of the device housing part 13a, and the package part P of the device D can be brought into contact with the sliding part 11d of the base member 11. Install it as follows. Therefore, when the cylinder is contracted, the urging force of the spring 23 acting between the base member 11 and the roof member 12 causes both members 11 and 12 to move toward the shaft 1.
7, the roof member 12 contacts the base member 11, and the device accommodating portion 13a is covered. When the cylinder further contracts, the entire orienter member 13 rotates downward about the rotation shaft 18, and at the stroke end position of the cylinder, the orienter member 13 is at a predetermined angle. It will be tilted.

[0020] Here, when the device D is received in a horizontal state, tilted downward, and fed into the inclined chute 30, the positioning member 24 and the through hole 25 are not provided, and instead, a locking member is provided. A pin 32 is provided on the base member 11 (or roof member 12), and this locking pin 32
is installed so as to be movable by a pin driving means 33 such as a cylinder between a position facing the sliding portion 11d of the device D and a position evacuated from the sliding portion 11d. By causing this locking pin 32 to protrude above the sliding portion 11d at least while the elevating motion is being performed, the device D in the device accommodating portion 13a is held so as not to fall off. Then, when the orienter member 13 is connected to the inclined chute 30, the device D in the orienter member 13 can be fed into the inclined chute 30 by displacing the locking pin to the retracted position.

[0021]

As explained above, the present invention has a base member and a roof member provided on the base member so as to be openable and closable, and the roof member is biased in the direction of closing the base member. At the same time, an extending portion is connected to the opposite side of the connecting portion to the side wall of the base member, and an elevating drive means is connected to the elongating portion, and the elevating driving means is configured to act on the elevating and elevating means of the orienter member. Since it is configured to have a displacement stroke corresponding to the angle and the opening/closing angle of the roof member,
Converts the posture of the IC device from a tilted state to a horizontal state,
Alternatively, it is now possible to transfer from a horizontal state to a tilted state, and the mechanism for displacing the roof member between the tilted state and the horizontal state has the function of opening and closing the roof member. A single driving means can perform the raising and lowering operations of the orienter member and the opening/closing operations of the roof member, resulting in effects such as the ability to significantly simplify the configuration of this driving means.
