Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an article sorting device, and in particular to an I.
The present invention relates to an improvement of an IC sorting device when supplying ICs from a loader section to a preheating section in a C handler.

[Prior Art] An IC handler is used by being incorporated into an automatic IC inspection device, and continuously transports a large number of ICs as objects to be inspected, and sequentially supplies them to the measuring section of the inspection head. This is a device that tests the IC by making contact with the terminals of the IC.

FIG. 6 is a schematic diagram showing the basic configuration of the IC handler.

A is a loader section that stores uninspected ICs and sends them out one after another.Generally, IC magazines 1 are stacked.
.

It is. Inside this IC magazine 1, there is a continuous line. . 3

:゛The ICs in IC magazine 1 are placed in preliminary heat treatment section B.
, while being guided by guide rails and sliding down one after another under its own weight, while being pre-treated to a temperature that meets predetermined inspection conditions. Preliminary treatments in this case include preheating and precooling.

The ICs that have passed through the uneven heat treatment section B are similarly guided by guide rails and are sequentially lowered vertically downward through the measurement section C, while being transferred to an automatic measuring device (@-inspection).

(not shown).

After the inspection, the ICs slide down under their own weight to the unloader section, but along the way, they are sorted by the classification section E according to the inspection results and slide down under their own weight through multiple lanes set up in parallel. Multiple rows of magazines 1a, lb, lc, le, if, Ig set in the unloader section

Now, in order to increase the processing efficiency in the measurement section C,
Generally, a plurality of lanes are provided within the measuring section C.

Correspondingly, a plurality of lanes are provided in the preheating processing section B as well. Therefore, a distribution FT<G (not shown in the figure because it is located inside) is provided between the loader section A and the preliminary heat treatment section B.

The function of the sorting section E and the vibrating molecule mG is to receive the IC, move it in a direction perpendicular to the lane, and send it to one of the plurality of lanes for the next process.
There are the following differences.

The sorting section E must send the inspected ICs to a predetermined lane according to the +yJ inspection results, while the sorting section G must send the uninspected ICs to a plurality of lanes (preprocessing section B) in a fixed order.
(lanes)).

FIG. 5 is an explanatory diagram showing the principle of such a conventional sorting device, in which one row of loader chute 2 and four rows of preheat chutes 3a, 3b are shown.

3c and 3d are provided in parallel at intervals.

Reference numeral 5 denotes a sorting chute that is driven back and forth as indicated by arrows a+b, and has the function of accepting ICs, temporarily storing them, and sending them out to the chute for the next process.

Here, four ICs 4a, 4b, and 4c are sent sequentially along the loader chute 2 from the left side of the figure.

4d are preheat chutes 3a and 3b, respectively.

Sort into 3c and 3d. Therefore, the distribution chute 5 moves left and right.

The distance that this distribution chute 5 must move is
It becomes as follows.

(2) Receive the leading IC 4a in the state shown, move it to the left by L, and feed it into the preheat chute 3a.

■Next, go back to the right by L to get to the position shown in the diagram, and pass through the second IC4b as it is, then go to Buri Heaton NEET 3b.
send to.

■Then, receive the third IC4c in the same position, move it to the right by L, and feed it into the preheat chute 3c.

■Next, go back to the left by L to get to the position shown in the diagram, and make the final rc
4d, moves to the right by 2L, sends it to the preheat chute 3d, moves further to the left by 2L, and returns to the initial position shown.

[Problem you are trying to solve] Part 41 of I--2 to 4: Allocate the IC after the steps.

Here, the distance that the distribution chute 5 should move left and right is 8L in total.

Therefore, the sorting processing speed becomes slow, which poses a problem for high-speed inspection.

Furthermore, when driving using an air cylinder or the like, the number of stroke control increases, the distance the piston rod moves also increases, and position control is complicated, making accurate positioning difficult.

Therefore, in order to simplify cylinder control, it is possible to combine several cylinders and control the position only by moving them forward and backward, but it is also possible to mount other cylinders on the piston rod of one cylinder. The driving mechanism becomes large, and the piping becomes complicated by the number of cylinders, and the piping parts are also moved together, making the structure of the entire mechanism complicated.

[Object of the Invention] The object of the present invention has been made in view of the problems of the prior art, and the purpose is to eliminate such problem blades and to solve the problem of a large number of continuously arranged lanes. 1] To provide an article sorting device that can quickly and efficiently sort parts (ICs) with a simple mechanism.

[Means for Solving the Problems] The means in the article sorting device of the present invention for achieving the above-mentioned objectives include a first passage and a plurality of lanes provided corresponding thereto. provided between the second passage,
What is the component sorting member that receives the parts from the first passage, moves at right angles to the transport direction, and distributes and supplies the received parts to a predetermined second passage among the plurality of passages? The dividing member performs distribution by being driven by a cylinder having multiple strokes.

[Operation] By controlling the movement of the article sorting member using a plurality of stroke cylinders in this manner, the sorting speed can be improved, the control becomes simple, and the drive mechanism thereof can be made compact.

[Example 1] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic diagram of an embodiment of the IC sorting device portion of an IC handler to which the article sorting device of the present invention is applied;
Fig. 2 is an explanatory diagram of a specific example of the article sorting drive section;
Figures (a) to 3(C) are explanatory diagrams of the drive control of the embodiment for the first kindergartener, and Figures 4(a) to 4(d) are, respectively.
are explanatory diagrams of the operation of the embodiment in each case.

Components that are the same as those in FIG. 5 are designated by the same reference numerals.

The shuttle base 6 is driven in the left and right direction by the reciprocating device 10 as shown by arrows a and b.
, two sorting chutes 5a and 5b are mounted parallel to each other with an interval between them.

Here, "-recording distribution chute 5 a * 5 b is I
This is a member having a function of temporarily storing C. In this embodiment, a case will be explained in which two distribution chutes are provided, but the number of distribution chutes may be one, three, or three. After that, it's fine. The intervals (=L) between these plurality of distribution chutes are set so as to correspond to the respective preheat chutes (that is, the chutes on the receiving side).

On the other hand, the reciprocating device 10 is a double stroke cylinder in which two cylinders are connected in tandem in series, as shown in FIG. Second cylinder 10a, l
It is composed of Ob. Then, the piston rod 10c of the first cylinder 10a moves forward and backward with a stroke corresponding to the above-mentioned interval, and the piston rod 10c of the second cylinder 10b moves forward and backward with a stroke corresponding to the above-mentioned interval.
d advances and retreats with a stroke of 2L, which is twice the interval.

Specifically, if L” is 50 mm, cylinder 1
0a is a cylinder with a so-called 50 mm stroke, and 10b is a cylinder with a 100 mm stroke.

Note that 11, 12, 13, and 14 are piping ports for intake/exhaust air of a double stroke cylinder as the reciprocating device 10, respectively.

Now, FIG. 3 (
a) to FIG. 3(c) and FIG. 4(a) to FIG. 4(d)
).

■As shown in FIG. 3(a), the first cylinder 10a is driven forward and the second cylinder 10b is driven backward,
With these force relationships, the first cylinder lOa pushes out the piston rod lod of the second cylinder 10b, and the second
The cylinder 10b is moved forward to the center position. When the reciprocating device 10 is controlled in this manner, the shuttle base 6 is positioned at the position shown in FIG. 4(a), which is taken as the initial position. At this time, the reciprocating device IO is
Distance L (from the reference position (center position of loader chute 2)
The shuttle base 6 is moved to the right by a distance m> to the center position of the distribution chute 5b.

As a result, the distribution chute 5a faces the loader chute 2, and the first IC 4a is received by the distribution chute 5a.

Note that the white arrows in each cylinder indicate the relationship between the direction of the force acting on the cylinder and the magnitude of that force.
The output of the cylinder 10a is larger than that of the second cylinder tab.

■Next, as shown in Figure 3(b), the first cylinder 1
0a is moved backward and the second cylinder 10b is driven forward. As a result, as shown in FIG. 4(b), the shuttle base 6 is moved to 1115 by a further distance of 11 tL from the position ①.
Move forward and move the shuttle base 6 to the left from the reference position! L
The center of the distribution shoe 5b and the position reference position match.

Therefore, the distribution chute 5a is arranged to face the preheat shoe 3a. The distribution chute 5b faces the loader chute 2 and the preheat chute 3b.

In this state, the first IC 4a is fed into the preheat chute 3a, and at the same time, the second IC 4b and the distribution shoe 5b are passed through and fed into the preheat chute 3b. then 3
The IC4c is received through the distribution chute 5b.

(2) Next, as shown in FIG. 3(a), the first cylinder 10a is driven forward and the second cylinder tab is driven backward. Then, as shown in FIG. 4(C), the shuttle base 6 is moved back to the right by a certain distance to reach the current position, and the reference position coincides with the center position of the distribution shoe 5a.

Here, the distributed chute 5a can be received at the last IC 4d.

- Then, as shown in FIG. 3(C), the first cylinder 10a is moved backward, and the second cylinder lOb is driven backward to move the shuttle base 6 further to the right by a distance +IIL.
move only. As a result, as shown in FIG. 4(d), the distribution shoes 5a and 5b are respectively preheated chutes 3
c, facing 3d. In this state, the third IC 4c is sent to the preheat shoe) 3d, and the last IC 4d is sent to the preheat chute 3c.

At this stage, all of the four ICs 4a to 4d have not been inspected, so it does not matter which IC is sent into which preheat chute.

Thereafter, the first cylinder 10a is driven forward and the second cylinder 10a is driven forward.
The cylinder 10b is driven backward to move the shuttle base 6 to the left by a distance 'mL' and return it to its original initial position as shown in FIG. 3(a).

In the above four steps (1) to (2), the shuttle base 6 makes one reciprocation from the left end to the right end by the reciprocating device 10, and the moving distance is 4L in total. Since this embodiment is provided with two distribution chutes, it is possible to control the movement over a distance 1/2 that of the conventional one. Therefore, the time required for the movement is reduced by i, and since two ICs are transferred simultaneously and in parallel in each of the steps (1) to (2), the time required for transferring the ICs is also significantly shortened.

By the way, by using a double stroke cylinder, three-stage movement control is possible by combining the forward and backward drive of two stages of cylinders, and the piping becomes simple. Therefore, it is not necessary to drive the cylinder by mounting another cylinder on the piston rod of the cylinder, making the control much more convenient, and making the device itself more compact.

By the way, in the embodiment, the cylinders are directly connected in two stages, but this may be a three-stage directly connected type stroke cylinder, or two or more cylinders may be used. In short, what is necessary is to control the distributing member to be moved by a cylinder that performs multiple strokes.

Further, the method of controlling the double cylinder in the embodiment is merely an example, and is assumed to be in its initial setting state.

For example, it may be possible to set the first cylinder in the forward position and the second cylinder in the backward position. A combination of these is possible.

[Effects of the Invention] As can be understood from the above description, the system is provided between the first passage and the second passage of a plurality of lanes provided correspondingly, and the part is removed from the first passage. It has a parts sorting member that receives and moves perpendicularly to the conveyance direction to sort and supply the received parts to a predetermined second path of the plurality of passages, and this parts sorting member has a plurality of stages. Since the distribution is performed by being driven by a cylinder having a stroke, the distribution speed can be increased, control is simple, and the drive mechanism is also compact.
