The present invention relates to a conveying apparatus for a cassette for separating the cassettes stacked between the loading pieces in order to transfer them to the loading portion or the unloading portion of the device, and more specifically, to transfer the cassettes separated from the loading loading fund in a stable state. It was made to be possible.

In general, the inspector that inspects the performance by producing the SOP and QFP type devices and removes one cassette located at the bottom of the cassette and transfers it to the supply rail. Then, after transferring it back to the element loading rail side, the elements contained in the cassette are sequentially supplied to the alignment block. After all the elements in the cassette are supplied to the alignment block, the bin caster is loaded on the unloading stack.

Accordingly, in the performance tester of the device, there is a need for an apparatus for transferring the cassette separated from the loading stack to the supply rail side to the device loading rail.

Conventionally, when one cassette separated from the loading stack is transported to the supply rail side, the pickup is transported to the upper portion of the cassette by the transport means, and the upper surface of the cassette is absorbed by the vacuum suction force and transported to the element loading rail side. If the lower surface is unstablely connected to the upper surface of the cassette (the upper surface of the cassette is formed with an indentation groove for accommodating elements, the flat surface is very small), the cassette may fall from the pickup when the cassette is transported due to the decrease in adsorption force. There was a case where the element fell and broke.

In addition, when the device to be tested for performance is a thin small outline package (TSOP), the thickness of the device is only about 1 mm, which is very weak to shock, which may have a fatal adverse effect on the characteristics of the device. There is a problem that the molded chip (Chip) is broken.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem in the related art, and an object thereof is to enable the cassette to be stably transferred to the element loading rail by a mechanical configuration.

As the link 23 is rotated by driving the cylinder by coupling the rod 26 of the cylinder 25, the spline shaft 8 fixed to one end of the link is rotated within a predetermined range.

Accordingly, the rotation shaft 15 coupled to the spline shaft 8 is rotated together within the rotation range of the spline shaft 8.

If the bearing 27 is coupled to the front end of the rod 26 coupled to the long hole 23a of the link 23 so that the bearing 27 is connected to the inner surface of the long hole 23a, the link 23 is operated. Noise caused by the friction of the connection is not generated, of course, the operation is made more smoothly.

The stopper 28 such as rubber is fixed to the bracket 24 to which one end (lower end) of the link 23 is connected.

This controls the amount of the link 23 falling when the link 23 is lowered and at the same time to prevent the impact and noise generated when one end of the link is connected to the bracket 24.

The driving means for transferring the slider 10 to the element loading position to be guided by the spline shaft 8 is provided with a step motor 29 as a driving source under the mounting plate 1 as shown in FIGS. 5 and 6. The first timing belt 34 is wound between the shaft 30 of the motor and the power transmission shaft 31 for transmitting the power of the motor to the slider side, respectively, by fixing the pulleys 32 and 33.

The pulleys 37 and 38 are fixed to one end of the power transmission shaft 31 and the shaft 36 supported by the bracket 35 to wind the second timing belt 39 on the pulley and the pulley 37. The third timing belt is fixed between the shaft 36 located at one side of the shaft and the shaft 42 fixed to the bracket 41 of the shaft of the element loading rail 40 by another pulley 43 and 44. Wind 45

The third timing belt 45 is mounted on the extension 46 of the slider 10, and then the top of the third timing belt 45 is fixed by covering the fixing piece 47 and fixing it with the bolt 48. As a result, the slider 10 is horizontally moved along the spline shaft 8.

Meanwhile, the fourth timing belt 53 is fixed between the pulleys 51 and 52 by fixing the pulleys 51 and 52 to the shaft 50 supported by the other side of the power transmission shaft 31 and the bracket under the mounting plate 1. And secure the connecting piece 54 fixed to the slider 10 on one side on the fourth timing belt with the fixing piece 55.

This is for the slider 10 to be moved along the spline shaft 8 in accordance with the positional change of the fourth timing belt 53.

In addition, a first elevating piece 57 is provided between the supply rails 6 to drive up and down by the driving of the cylinder 56, and the cylinder 58 is moved up and down between the element loading rails 40. The second lifting piece 59 is installed.

This raises the cassette 2 mounted on the supply rail 6 horizontally with the holder 19, or the cassette conveyed as the gripper is transported to the element loading rail 40 by holding the catheter in the supply rail. Is to stably seat the device loading rail (40).

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

First, the lifting member (not shown) installed between the loading members is lifted up and connected to the cassette located at the lower side while the cassette 2 containing the elements is sequentially loaded between the loading members 3. At the same time, when the stopper (not shown) holding the cassette retreats, the lowermost cassette is placed on the lifting piece.

In this state, when the elevating piece advances the stopper that has retreated at the same time as the one-step down by the operation of the cylinder, the stopper is inserted between the lowermost cassette and the second cassette to hold the second or more cassettes from the lowermost.

Then, when the elevating piece descends by the continuous operation of the cylinder, one cassette 2 separated from the loading stacking piece 3 is placed on the first loader 5.

In this way, when one cassette 2 is separated from the loading stack 3 and placed on the first loader 5, the first cylinder 4 is operated to transfer the first loader 5 to the supply rail 6. Since the cassette (2) containing the element is conveyed to the supply rail side, the front end of the cassette (2) conveyed by the first loader (5) is caught by the stopper (7) fixed to the mounting plate (1) At the same time the position of the cassette in the feed rail 6 is determined.

After one cassette 2 is separated from the loading stack 3 by the operation as described above and positioned on the supply rail 6 as shown in FIG. 5 (a), it is installed below the mounting plate 1. The first lifting piece 57 is lifted by the cylinder 56 so that the cassette 2 placed on the first loader 5 is separated from the first loader, and the holder 19 and the holder 19 as shown in FIG. Place it on the horizon.

When the cassette 2 is positioned on the holder 19 and a horizontal line, as shown in FIG. 5 (b), a pair of grip portions installed on both sides of the cassette 2 are driven to hold both sides of the cassette.

This will be described in more detail as follows.

When the cylinder 25 fixed to the bracket 24 is operated, the rod 26 of the cylinder is fitted into the long hole 23a of the link 23 and one end is fixed to the spline shaft 8 so that the rod is centered on the spline shaft. 4 is rotated in the arrow direction (clockwise) shown in FIG. 4A, and the spline shaft is also rotated by the amount of rotation of the link 23. FIG.

Since the bearing 27 coupled to the upper portion of the rod 26 is connected to the inner surface of the long hole 23a during the operation, the operation is smoothly performed and noise is minimized.

When the spline shaft 8 is rotated, the rotating shaft 15 is integrally formed with the intermediate shaft 13 and the key 14 on the spline shaft, and the rotating shaft is rotated together so that the extension piece 16 fixed to the lower portion of the rotating shaft 16 is rotated. ) Pushes the plate 18 to the left in the drawing of FIG.

Accordingly, the plate 18 coupled to each slider 10 is moved to the cassette 2 side as shown in (b) of FIG. 4 and (c) of FIG. 5 while compressing the spring 20. The holder 19 fixed with 17) holds both sides of the cassette.

In the operation as described above, as shown in FIG. 2, the pivot shaft 15 is not fixed to the slider 10 and is coupled to the fixed plate 11 and the bearing 63, and the spline shaft 8 is fixed to the fixed plate ( And the slider 10 does not move because the spline shaft 8 is idling on the fixed plate 11.

In this way, after the holder 19 holds the cassette 2 lifted by the first lift piece 57 by the grip portion, the cylinder 56 is driven to lower the first lift piece 57 that has been raised.

As a result, the cassette 2 containing the element is supported by the holder 19 and floated in the air. In the state in which the holder supports the cassette, the rod 26 of the cylinder 25 is lifted so that the spline shaft 8 Continue to rotate.

According to the operation as described above will be described the process of holding the cassette 2 transferred to the supply rail 6 to the element loading rail 40 by holding the gripper.

As shown in FIG. 6 (b), when the step motor 29 installed in the lower part of the mounting plate 1 is driven while the grip unit holds the cassette 2, the power of the step motor causes the first timing belt 34 to operate. Since it is transmitted through the power transmission shaft 31 is rotated.

When the power transmission shaft 31 is rotated, power is transmitted through the pulley 37 and the second timing belt 39 fixed to one end of the power transmission shaft, as shown in FIG. 5, and thus the third timing belt 45. And the fourth timing belt 53 is moved toward the element loading rail 40 through the pulley 53 fixed to the other end, so that the fixing pieces 47 and 55 are respectively attached to the third and fourth timing belts. The fixed slider 10 is conveyed by the conveying amount of the third and fourth timing belts.

At this time, the intermediate shaft 13 installed inside the slider 10 is fitted to the spline shaft 8 and the bearing 21 coupled to the extension piece 16 rotates the plate 18 by the rotation of the spline shaft 8. Since the slider 10 and the holder 19 do not flow continuously, the cassette 2 is stably horizontally moved to the element loading rail 40 without moving.

In this operation, the two sliders 10 are connected to the connecting piece 22, so that they are horizontally moved more stably along the spline shaft 8 while maintaining a balance of forces.

The cassette 2 held by the holder 19 is moved to the element loading rail 40 as shown in FIG. 6 (c) by horizontal movement of the slider 10. When the driving of the step motor 29 is stopped, the element loading is performed. Since the second lifting piece 59 provided between the rails 40 is driven up by the driving of the cylinder 58, the second lifting piece is connected to the bottom surface of the cassette.

After the second lifting piece 59 is connected to the bottom surface of the cassette 2, the holder 19 holding both sides of the cassette releases the holding state of the cassette.

To this end, when the rod 26, which has been raised, is lowered by the driving of the cylinder 25, the rotated spline shaft 8 is reduced to an initial state, so that the pivot shaft 15 integrated with the spline shaft is also reduced to an initial state.

At this time, one end (lower) of the rod 23 is connected to the stopper 28 such as rubber fixed to the bracket 24, thereby minimizing the impact and noise caused by the restoration of the link 23.

Accordingly, when the extension piece 16 fixed to the pivot shaft 15 is kept vertical as shown in FIG. 4 (a), the mill plate 18 pushed by the bearing 21 installed on the extension piece 16 is removed. Since the spring 920 is reduced to the initial state by the restoring force of the spring 920, the holder 19 fixed to the contact plate and the rod 17 is separated from the cassette 2.

When the holder 19 is separated from the cassette 2, the cassette 2 held in the holder is placed on the upper part of the second lifting piece 59, so that the second lifting piece 59 is driven by the cylinder 58. When the lowering, the cassette is placed on the upper surface of the device loading rail 40.

Accordingly, since the cassette placed on the element loading rail 40 is accurately positioned by a separate positioning means, a pickup (not shown) sequentially loads the elements contained in the cassette into the alignment block.

After all the elements contained in the cassette are loaded in the above operation, the second lifting piece 59 lifts the cassette 2 on the upper surface of the element loading rail 40 and at the same time the second loader 60 moves the element loading rail. And the second lifting piece 59 is lowered so that the cassette 2 is placed on the upper surface of the second loader 60 so that the loaded bin tray of the device is loaded on the unloading stacking piece 62. Will be loaded.

The operation of stacking the bin tray on the unloading stacking piece 62 is performed in the reverse order of the operation of separating the cassette from the loading stacking piece 3, and thus a detailed description thereof will be omitted.

On the other hand, after one cassette 2 is transferred to the element loading rail 40, the gripper is transferred along the spline shaft 8 by the reverse rotation of the step motor 29 to be in an initial state. The cassette loaded in (3) can be separated and transferred to the element loading rail side.

As described above, the present invention securely seats the cassette containing the element on the element loading rail side in the state where both sides of the cassette transferred onto the supply rail are held on the element loading rail side, so that the cassette falls during transportation of the cassette. The shock to the device is prevented in advance, and all the operations are performed correctly, so that no shock occurs during the operation, and thus, the productivity is improved according to the automation of the device.
