Description

{APPARATUS FOR OPENING TRAY}

The present invention relates to a tray opening device for opening a stacking tray for loading electronic components.

Generally produced electronic components are carried on the stacking tray.

The electronic components loaded in the stacking tray may be detached due to impact during transportation or tilting of the stacking tray. Therefore, depending on the type of the stacking tray, a gripper for gripping the electronic component is provided.

Particularly, in the case of a stacking tray provided for testing mounted electronic components, the configuration of the punching machine is also necessary for the sophisticated electrical contact between the electronic component and the tester.

Therefore, in order to load electronic components into the stacking tray or to withdraw electronic components from the stacking tray, the stacking tray must be opened by operating the gripper. Therefore, an opening device for opening the stacking tray is required.

Generally, in order for the loading tray to be opened by the opening device, the loading tray must be accurately aligned at a position where it can be opened by the opening device. This requires a technique for aligning the stacking tray.

The conventional opening device is composed of a mounting plate which is lifted and lowered by a driving cylinder and an opening pin and an alignment pin which are provided on the mounting plate. And the opener consists of an open plate for opening the stacking tray and a lifting cylinder for lifting the open plate.

Such a conventional opening device operates in such a manner that the mounting plate is primarily lifted by the driving cylinder, the mounting tray is finely aligned by the alignment pin, and the loading tray is opened while the open plate is lifted secondarily by the lifting cylinder .

However, the conventional opening device has the following problems.

First, since the number of driving sources is large, the production unit price increases.

Second, since the aligning pin is operated by the driving cylinder, damage to the stacking tray or the aligning pin occurs in some cases.

Third, the number of driving sources is so large that it is necessary to consider interference avoidance with other components, thereby increasing design difficulties.

The stacking tray LT is provided with 16 pairs of holding members PE ₁ and PE ₂ paired with each other. And holding members (PE _1, PE _2), the electronic component is to be inserted gripping groove (IS) This is formed, holding members (PE _1, PE ₂₎ lower part of the guide hole opening downward (GH _1, GH ₂ of Is formed.

Further, the holding member by the spring (S _1, S ₂₎ also between the holding members (PE _1, PE ₂₎ in a pair, as shown in a conceptual side view of the third to the elastic force acts in the direction to face each other (PE _1, PE ₂ are elastically supported. Accordingly, the grip member in the pair (PE _1, PE ₂₎ on the electronic component (ED) caught tightly between which is held in the form.

The gap between the pair of holding members PE ₁ and PE ₂ must be widened to load or unload the electronic component ED onto the stacking tray LT as required. To this end, as shown in FIG. 4 (a), which is highly exaggerated, a pair of open pins G2 and G3 having a mutual distance L ₂ wider than the gap L ₁ between the pair of guide holes GH ₁ and GH ₂ , (OP ₁ , OP ₂ ) are required. That is, when the pair of opening pins OP ₁ and OP ₂ are inserted into the pair of guide holes GH ₁ and GH ₂ , the pair of holding members PE ₁ and PE 2 ₂ ). Of course, the opening pin (OP _1, OP ₂₎ a guide hole fall from (GH _1, GH _2), holding members (PE _1, PE ₂₎ the interval narrowing As between the holding members (PE _1, PE ₂₎ in a pair The electronic component ED is gripped by the gripper. As shown in FIG. 4 (c), even though the gap L ₁ between the pair of holding members PE ₁ and PE ₂ is narrowed, the center of the opening pins OP ₁ and OP ₂ C are located inside the guide holes GH ₁ , GH ₂ .

On the other hand, the loading tray LT is provided with a matching hole AH opened downward, and a rectangular fixing hole FH is formed on both left and right sides. The matching hole AH and the fixing hole FH will be described later in the relevant portions.

<Description of open device>

FIG. 5 is a schematic partially exploded perspective view of a tray opening device 500 (hereinafter abbreviated as "opening device") according to an embodiment of the present invention, and FIG. 6 is a conceptual Side view.

The opening device 500 according to the present embodiment includes an opening plate 510, an elevator 520, a pair of aligners 530, a mounting plate 540, and a pair of fixing devices 550.

The open plate 510 is provided so as to be movable up and down. The open plate 510 is provided with an open plate 510 protruding upward to open the loading tray LT so that the electronic part ED can be loaded on the loading tray LT or the electronic part ED can be drawn out from the loading tray LT And open pins OP ₁ and OP ₂ . The open pins (OP ₁ , OP ₂ ) are two pairs and are provided with 16 pairs. The upper part of the open pin (OP ₁ , OP ₂ ) has a narrower width toward the upper end. Distance between the opening pin (OP _1, OP ₂₎ with each other in a pair, where (L _2), the gripping member in the pair to each other (PE _1, PE ₂₎ holding members interval in a pair with each other in the narrowed state between (PE ₁ wider than a distance (L ₁₎ between the guide hole (GH _1, GH ₂₎ forming a respective pair formed in the PE _2). Further, the open plate 510 has long guide posts 511 in the downward direction.

The elevator 520 lifts the open plate 510. The elevator 520 is preferably provided as a cylinder in view of reducing the production cost, but may be replaced with a motor or other driving source depending on the implementation. The elevator 520 lifts the open plate 510 to open the loading tray LT by bringing the open pins OP ₁ and OP ₂ into contact with the loading tray LT located on the upper side, And closes the stacking tray LT by releasing the contact of the open pins OP ₁ and OP ₂ with respect to the stacking tray LT. Since the opening pins OP ₁ and OP ₂ are inserted into the guide holes GH ₁ and GH ₂ of the gripping members PE ₁ and PE _{2 while} being in contact with the stacking tray LT, The gap between the gripping members (PE ₁ , PE ₂ ) is widened. And thereby the loading tray LT is opened.

A pair of aligners 530 aligns the stacking tray LT. To this end, the pair of aligners 530 includes a coupling member 531, a matching member 532, and a restoring spring 533, respectively.

The engaging member 531 is coupled to the opening plate 510 and moves up and down together with the opening plate 510. The coupling member 531 is provided with two through holes TH penetrating in the vertical direction, and a lubricating member 531a is provided on the inner inner wall of the through hole TH. Here, the lubrication member 531a may be a ball bush.

The matching member 532 is coupled to the engaging member 531 and is provided so as to be relatively movable relative to the engaging member 531. [ The matching member 532 has a matching pin 532a, two guide rods 532b, and a blocking end 532c.

The matching pin 532a protrudes upward to be inserted into the matching hole AH of the stacking tray LT when the opening plate 510 is lifted and has a shape in which the width of the upper portion is narrowed toward the upper end . This matching pin 532a is moved in the direction in which the open pins OP ₁ and OP ₂ are lifted up to contact the stacking tray LT and inserted into the guide holes GH ₁ and GH ₂ Is positioned at a height that allows the stacking tray LT to be aligned prior to opening of the stacking tray LT by first being inserted into the hole AH. In this embodiment, the upper end of the registration pin 532a is located higher than the upper end of the opening pins OP ₁ and OP ₂ , but depending on the lower structure of the loading tray, the registration pin may be positioned at the same or lower position As shown in FIG.

The guide rods 532b are inserted into the respective through holes TH so as to be capable of sliding up and down through the lubrication member 531a. These two guide rods 532b guide the relative lift movement of the mating member 532 relative to the mating member 531 when the mating member 532 is relatively lifted relative to the mating member 531. [ Since the lifting and lowering of the matching member 532 is guided by the two guide rods 532b, the wobbling and twisting in the horizontal direction are prevented. Of course, depending on the necessity, one through hole and one guide rod may be provided, or three or more holes may be provided if necessary.

The preventing end 532c prevents the matching member 532 from being displaced upward due to the elastic force applied by the restoring spring 533 upward. Of course, the prevention step 532c may be formed integrally with the guide rod 532b or may be provided to be coupled to the guide rod 532b.

The restoring spring 533 is provided as an elastic member for elastically supporting the matching member 532 upward with respect to the engaging member 531. [ That is, the restoring spring 533 is an operating member that allows the mating member 532 to be relatively lifted and lowered relative to the engaging member 531. [

The mounting plate 540 is provided with a guide pipe 541 through which the guide pillars 511 are inserted to guide the lifting and lowering of the opening plate 510. Here, the guide pipe 541 may be provided with a lubrication member such as a ball bush.

A pair of fasteners 550 are installed on the mounting plate 540.

The fixing device 550 includes a fixing member 551 and a moving device 552.

The holding member 551 is provided so as to move forward or backward in the opposite direction to the open plate 510 side by the moving unit 552. The fixing member 551 prevents an excessive rise of the stacking tray LT by the fixed end 551a protruding toward the opening plate 510. [ The fixed end 551a is inserted into or removed from the fixing hole FH of the loading tray LT placed on the opening plate 510 in accordance with the forward and backward movement of the fixing member 551. [

Of course, depending on the implementation, the fixed end may be provided to hang over the top of the stacking tray LT. In this case, the retracting movement of the fixed end may not be necessary.

The operation of the opening device 500 having the above configuration will be described below.

7 is a state in which the electronic component ED is roughly located at the loading position where the current loading tray LT is closed and the electronic component ED is loaded. At this time, a separate stopper may be provided to place the stacking tray LT in a required position. The movable member 552 is operated to advance the fixing member 551 toward the stacking tray LT so that the fixed end 551a of the fixing member 551 is inserted into the fixing hole FH of the stacking tray LT.

In order to load the electronic component ED in the state of Fig. 7, the stacking tray LT must be opened. To this end, the elevator 520 of the opening device 500 operates to raise the open plate 510. As the open plate 510 rises, the aligner 530 coupled to the open plate 510 also ascends. The opening pins OP ₁ and OP ₂ are inserted into the guide holes GH ₁ and GH ₂ of the gripping members PE ₁ and PE _{2 as} shown in FIG. (532a) is inserted into the matching hole (AH). The matching pin 532a is completely inserted into the matching hole AH in accordance with the continuous rise of the open plate 510 and the ascending of the matching pin 532a so that the position of the stacking tray LT is accurately aligned . 9, the upper surface of the matching member 532 is brought into contact with the lower surface of the stacking tray LT. 10, the bottom surface of the fixing hole FH is brought into contact with the bottom surface of the fixed end 551a by the continuous rising of the opening plate 510. [ As a result, further rise of the stacking tray LT is prohibited, and further rise of the registration member 532 is prohibited. Therefore, after the state shown in FIG. 10, the stacking tray 540 is stopped by the stacking tray LT and is not allowed to rise. When the open plate 510 further rises in the state of Fig. 10, only the open plate 510 and the engaging member 531 are lifted in the state where the upward movement of the mating member 532 is stopped, so that the restoring spring 533 is compressed . That is, the matching member 532 stopped by the stacking tray LT is lowered relative to the engaging member 531 while pressing the restoring spring 533 downward. The opening pins OP ₁ and OP ₂ are inserted into the guide holes GH ₁ and GH ₂ as shown in Fig. 11 by the rise of the open plate 510 following the state of Fig. 10, PE ₁ , PE ₂ ) is opened to open the loading tray LT.

11, the electronic parts ED are placed between the gripping members PE ₁ and PE ₂ which are paired with each other by performing the loading operation of the electronic parts ED.

And when the loading tray (LT) and electronic components (ED) are both mounted on, to open plate 510 is lowered by the pressing strongly the electronic component (ED) holding members (PE _1, PE ₂₎ forming a pair with each other gripping Lt; / RTI &gt;

Of course, in the case of unloading the electronic part ED from the loading tray LT, an operation for unloading the electronic part ED is performed after opening the loading tray LT in the same manner as above.

The reason for limiting the excessive rise of the matching pin 532a through the structure in which the matching member 532 is resiliently supported by the restoring spring 533 in the present embodiment is that when the matching pin 532a rises excessively, This is because of interference with other structures of the equipment or other structures of the stacking tray (LT). In other words, there is a great limitation in constructing the matching pin 532a in the vertical direction. Therefore, in this embodiment, after the aligning pin 532a performs the aligning function of the stacking tray LT through the engaging structure using the restoring spring 533, the aligning pin 532a is prevented from rising further.
