The present invention relates to a device loading machine, and more specifically, to a QFP (Quad Flat Package) type produced in a manufacturing process to sequentially load a device on a burn-in test board.

The conventional device loading machine is in the form of FIG. 1, in which a rotating plate 2 having a plurality of recessed grooves 2a on the upper portion of the main body 1 is rotatably installed by a cylinder 3, and the rotating plate Rail (4) is formed on one side of (2), and when the cylinder 3 is operated by placing a slide (not shown) in which the device is inserted into the recessed groove 2a, the rotating plate 2 is rotated at a predetermined angle. Since the device is inclined, the device inserted in the sleeve is directed along the rail 4.

And the upper side of the rail 4, the suction block (6) formed with the handle (5) on both sides is elastically installed by the slide unit (8) and the spring (9) moving along the guide rail (7) and the guide rail Board holders 11 on which burn-in boards 10 are seated are provided between the guides, and a set point plate 12 for positioning the slide unit 8 by one step is provided on the guide rail 7 on one side. It is fixed.

Therefore, when the rotating plate 2 is rotated by the cylinder 3 to attract the device drawn on the rail 4, the operator grasps the handle 5 of the adsorption block 6 and lowers the adsorption block 6. The device is adsorbed to the lower part of the adsorption block 6 by the vacuum pressure generated in the adsorption pump 13.

When the slide unit 8 is pulled toward the set point plate 12 while the device is attracted to the adsorption block as described above, the slide unit 8 moves along the guide rail 7 to be fixed to the upper part of the burn-in board 10. It stops in line with the line of the socket.

This is possible by matching the positions of the recesses formed in the socket and the set point plate 12 when setting the initial burn-in board 10 to the board holder 11.

Thereafter, when the worker grasps the handle 5 of the suction block 6 and presses it down strongly, the pressure of the suction block 6 is removed and the lead of the device is inserted into the socket of the burn-in board 10.

Then, when the external force is removed from the handle 5, the adsorption block 6 is lifted by the restoring force of the spring 9 so that the adsorption block 6 is moved to the rail 4 side and rotated by the operation of the cylinder 3 at the same time. Since the copper plate 2 is inclined, the device to be sent out is adsorbed as described above to perform continuous operation.

When all the devices are inserted into the sockets on the burn-in board 10 by the operation as described above, the new burn-in board is replaced, and when all the devices in the sleeve are discharged, the worker rotates the new sleeve filled with the devices. It is inserted into the recess groove (2a).

However, such a conventional device loading machine had to be loaded by moving the device drawn out on the rail 4 by the worker to the suction block 6 by hand and then moving to the burn-in board 10 side. Since the sleeve had to be manually replaced on the concave groove 2a, there was a problem that the work efficiency was lowered.

The present invention has been made to solve such a problem in the prior art, by simply placing a plurality of sleeves in the loading section and the burn-in board on the board holder so that the adsorption unit can sequentially load the device on the burn-in board The purpose is to realize the automation of the device.

According to an aspect of the present invention for achieving the above object, a loading portion installed on one side of the main body and a lowermost sleeve loaded on the loading portion for loading a plurality of sleeves filled with a device between a pair of loading plates; A loading unit for separating the loads and transferring them in a perpendicular direction to the loading unit and a rail installed at an angle so that the slides conveyed by the transfer unit are inclined at one time, and the devices contained in the sleeves are inclined, taking out and loading the burn-in board; There is provided a device loading machine comprising a burn-in board conveying unit for transferring one burn of the burn-in board as one step as the device is finished loading one line of the burn-in board.

The sleeve 16 filled with the device 17 is stacked in the insertion groove 15a and operated by the cylinder 18 as shown in FIG. 8 to the lowermost outer side of the insertion groove of the loading plate 15. The stopper 19 to be moved forward and backward is installed to control that the sleeve 16 falls to its own weight.

The stopper 19 operates simultaneously to control the free fall or free fall of the sleeve 16 in each insertion groove 15a.

The conveying part which conveys the sleeve 16 separated from the insertion groove 15a is a pair of 1st mounting block 20 so that it may be located between each loading board 15, as shown in FIG. The first cylinder 21 is installed to be elevated and lifted, and the lead screw 23 is rotated by the driving of the motor 22 to the inside of the first seating block, so that it is transferred in a direction perpendicular to the mounting plate 15. The slide plate 24 is possibly coupled to the lead screw 23 by screwing, and the pair of second seating blocks 25 having recessed grooves 25a are lifted by the third cylinder 26 in the slide plate. It is possibly installed.

And the take-out part which draws in the rail 27 inclined by the predetermined angle to the slide 16 installed at one end of the conveyance part is as shown in FIG. 2, FIG. 3, FIG. 5, FIG. (28) is rotatably installed about the shaft (30) by the rotation cylinder 29, the grip block 31 is installed on the one side of the swing block so as to be elevated by the fourth cylinder (32). The slide 16 which is moved to the swing block 28 is gripped. On one side of the swing block, a rail 27 waiting for the device taken out of the sleeve is inclined at a predetermined angle from the horizontal plane.

The loading section for absorbing one row of devices 17 located at the bottom of the rail 27 at once and loading them into the socket 34 of the burn-in board 33 is shown in FIGS. 2, 6, 9, and 10 As shown in FIG. 2, the base 36 is rotatably installed on the mounting plate 35 positioned on both sides of the rail 27, and connected to the shaft 37 exposed on one side. The pin 38 is fixed and connected to the first link 41 fitted in the first cam groove 40 of the rotating plate 39 to the connecting piece as shown in FIG. The first connecting rod 43 which moves up and down is connected as the pivot moves about the shaft 42.

In addition, the lifting piece 44 is coupled to the base 36 so as to be lifted and lowered, and the second link 46 moves the shaft 42 on one side of the lifting piece by the rotation of the rotating plate 39 as shown in FIG. The second connecting rod 47 which moves up and down as the pivoting movement is connected to the center, and the head 48 for adsorbing the device 17 at the bottom of the rail 27 in accordance with the vacuum pressure generated at the bottom of the lifting piece 44 Is fixed.

The first cam groove 40 into which the first link 41 is fitted consists of a large diameter portion 40a and a small diameter portion 40b, and concentric circle sections A and B are formed in the large diameter portion and the small diameter portion.

As shown in FIG. 10A, when the connecting portion of the first link 41 is positioned in the concentric section A of the small diameter portion 40b, the head 48 is rotated toward the rail 27. Is rotated while the device 17 is adsorbed, and when the connection portion of the first link 41 is positioned in the concentric section B of the large-diameter portion 40a, the head adsorbing the device 17 ( This is to ensure that 48 remains vertical while loading device 17 onto burn-in board 33.

In addition, as shown in FIG. 10 (b), when the second link 46 is located at the small diameter portion 45b of the second cam groove 45, the head 48 rotated in accordance with the rotation of the base 36. Is lowered to the position connected with the upper surface of the device 17 located at the lowest end of the rail 27 to adsorb the device, and when the lift piece 44 is positioned at the large diameter portion 45a, the lifting piece 44 of the burn-in board 33 This is to allow the device 17 adsorbed to the head 48 to be loaded onto the burn-in board by rotating up to the socket 34.

As the device is loaded in one row of the socket 34 fixed to the burn-in board 33, the burn-in board transfer part for transferring one step of the burn-in board is rotatably installed on the main body 14. The lead screw is mounted to the lead screw (330) on which the burn-in board 33 is mounted, and a motor 51 for rotating the lead screw is fixed to one end of the lead screw.

At this time, the transfer table 50 is guided to the guide rail 52 to perform a linear reciprocating motion.

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

First, if the slide 16 filled with the device 17 is placed in the insertion groove 15a formed in the loading plate 15 of the loading portion, and the power switch (not shown) is turned on, (a) of FIG. As described above, the first cylinder 21 and the third cylinder 26 operate simultaneously to raise the first and second seating blocks 20 and 25.

At this time, the slide plate 24 of the conveying part is moved to the loading part side, and the first seating block 20 is spaced apart by the thickness of the sleeve from the lowermost sleeve 16 loaded on the loading plate 15. It is located at a position slightly higher than the mounting block 25.

In this state, when the cylinder 18 operates and the stopper 19 is retracted as shown in FIG. 8 (b), the holding state of the sleeve 16 located at the lowermost position in the insertion groove 15a is released. 16 is dropped by the ground and seated on the first seating block 20.

Then, the retracted stopper 19 is advanced as shown in FIG. 8C by the operation of the cylinder 18 to shed the second lower sleeve 16 at the same time as the first cylinder 21 is returned to its initial state. When reduced, the first seating block 20 is lowered as shown in (c) of FIG. 7, so that the sleeve 16 on the first seating block 20 is equal to the number of insertion grooves 15a formed in the mounting plate 15. ) Will be put on.

As a result, the sleeve 16 placed on the first seating block 20 is placed on the second seating block 25 that is raised.

After the three slaves 16 are seated on the second seating block 25 as described above, the motor 22 is driven to transfer the slide plate 24 to the right by one step, thereby forming the second seating block 25. The concave groove 25a coincides with the insertion groove 15a of the loading plate 15, thereby allowing the sleeve 16 to be seated in the concave groove 25a in turn.

With the second seating block 25 seating all twelve sleeves 16 in the recess 25a in this operation, the swing block 28 of the outlet portion is lowered according to the operation of the rotary cylinder 29. A horizontal state is achieved.

At this time, the sebum block 31 rotatably installed on the swing block 28 is lifted by the fourth cylinder 32 and the support block 53 is slightly lower than the lower end surface of the sleeve 16 being conveyed. Since the sleeve 16 is transported to the outlet side, it does not cause mutual interference.

When the lead screw 23 is rotated by the driving of the motor 22, the slide plate 24 coupled to the lead screw 23 by screwing moves to the take-out part, so that the second seating block fixed to the slide plate 24 ( 25) is stopped in a state located above the swing block 28.

In this state, when the second seating block 25 is lowered by the restoring force of the third cylinder 26, the sleeve 16 is placed on the support block 53, so that when the fourth cylinder 32 is operated, the link ( The gripping block 31 connected to 54 descends about the shaft 55 to grip the delivery side of the sleeve 16.

Simultaneously with the above operation, the slide plate 24 is reduced to the initial state by the reverse rotation driving of the motor 22.

Thereafter, when the rotary cylinder 29 is operated to rotate the swing block 28, the swing block is inclined at a predetermined angle (same as the inclination angle of the rail) around the shaft 30 as illustrated in FIG. 9. Since the outlet port is made to coincide with the inlet of the rail 27, the device 17 contained in the sleeve 16 is sent out at once and waits on the rail 27.

As described above, the operation of supplying the device onto the rail is provided with a sensor (not shown) for detecting the presence or absence of the device in the middle of the rail 27 to drive the feeder and the drawer as the sensor does not detect the device. In this way, the device is continuously supplied to the rail 27.

The operation of loading one row of twelve devices 16 located at the bottom of the rail 27 inclined in turn into the burn-in board 33 will be described in detail as follows.

The first and second cam grooves 40 and 45 formed in the rotating plate 29 in the initial state in which the device 16 is positioned on the rail 27 are provided with the first and second links 41 and 46 as shown in FIG. ) Is located.

In this state, when the rotating plate 39 is rotated by the driving of the motor, the first and second connecting parts 43 and 47 connected to the first and second links 41 and 46 according to the shapes of the first and second cam grooves 40 and 45. This sequential lifting movement.

That is, in the state as shown in (a) of FIG. 10, the connecting portion of the first link 41 moves along the first cam groove 40 to reach the concentric circle section A by the clockwise rotation of the rotating plate 39. As the distance between the connecting portion of the first link 41 and the center O1 of the rotating plate 39 is closer, the first link 41 is rotated clockwise about the axis 42, and thus the first link ( Since the first connecting rod 43 connected to 41 is lifted up, the base 36, which is positioned as a solid line in (a) of FIG. 9, is rotated like a dashed line about the axis 37 so that the head 48 is railed. It is located on the vertical line with the device 17 located at the lowest end of the (27).

As described above, the second link 46 fitted into the second cam groove 45 formed on the other side of the rotating plate 39 when the base 36 is rotated has a second cam groove ( 45 is moved along the 45 to rotate the second link 46 in the clockwise direction while reaching a position shorter than the distance between the center (O2) of the initial state, and as a result of the rotation of the base 36 and the second connecting rod (47) Compensation for the variable position of the connecting portion of the piece 44.

After that, when the connecting plate of the second link 46 is positioned in the small diameter portion 45b of the second cam groove 45 by rotating the rotating plate 39, the connecting portion of the second link is rotated in the state in which the base 36 is rotated. Since the second link 46 is rotated in the counterclockwise direction about the axis 42 because the distance from the center (O2) was located in the end, the lifting piece 44 is guided to the base 36 Descends.

At this time, the descending distance is until the head 48 fixed to the bottom surface of the elevating piece 44 is connected to the upper surface of the device 17 located at the lowest end of the rail 27, which is the small diameter portion 45b and the center ( This is possible because the distance L1 between O2) is appropriately set.

According to the operation, when the head 48 is connected to the upper surface of the device 17, the vacuum pressure is transmitted through the hose 56 connected to the elevating piece 44, so that the device 17 located at the bottom of the rail 27 Adsorbed to the head 48.

As such, when the head 48 adsorbs the device 17, the connection portion of the first link 41 positioned in the first cam groove 40 is moved along the concentric section A, so that the base 36 is rotated. Will be maintained.

During the device adsorption section C of the second cam groove 45, the head 48 adsorbs the device 17 located at the lowermost end of the rail 27, and when it is out of the section C, the center O2 of the rotating plate 39 and Since the second link 46 is rotated in the clockwise direction so that the second link 46 is shorter than the connecting part distance l1 of the second link 46, the lifting piece 44 is reduced to the base 36 in an initial state.

In this way, when the lifting piece 44 is reduced to the initial state, the connection portion of the first link 41 fitted in the first cam groove 40 passes through the concentric section A, which is the base rotation section, and the center of the rotating plate 39 (O1). ) And the connection distance between the first link 41 is moved to the section B as the distance away from the base 36 is maintained in a vertical state.

After that, when the rotating plate 39 is continuously rotated, the connecting portion of the first link 41 fitted in the first cam groove 40 is passed through the concentric circle section B, thereby maintaining a vertical state, but not in the second cam groove 45. The connecting portion of the fitted second link 46 is passed through the cam groove section that is gradually away from the center (O2), the lifting piece 44 coupled to the base 36 is lowered.

At this time, the lifting piece 44 because the distance (L2) of the second cam groove 45 passing through the connection portion of the center O2 and the second link 46 is farther than the distance (1) falling when the device 17 is attracted. ) Is lowered more.

Accordingly, when the vertex portion of the loading section D passes through the connecting portion of the second link 46, the elevating piece 44 is located at the bottom dead center and the device 17 adsorbed to the head 48 is burn-in board 33. The loading of the socket 36 is completed, at which time the vacuum for the adsorption of the device 17 is released.

After loading the device 17 adsorbed to the head 48 in this way, the lifting section 44 is raised because the cam groove section where the distance from the center O2 is gradually shortened to the connecting portion of the second link 46 is passed. At the same time, the base 36 is maintained in a vertical state because the concentric circle section B is passed until the lifting piece 44 is completed.

On the other hand, when the device 17 in a row is loaded in the socket 34 of the burn-in board 33, the motor 51 is driven to rotate the lead screw 49, so the carriage 50 screwed to the lead screw is One pitch (pitch: center distance of the socket) is transferred and the driving of the motor 51 is stopped.

What has been described so far has described a state in which a single line of the device 17 taken out on the rail 27 is loaded into the socket 34. The loading operation of the device is performed in the socket 34 of the burn-in board 33. It continues to run until 17) is fully loaded (8 lines), then the operation of the device is suspended.

Accordingly, the operator can replace the burn-in board that has been loaded, thereby enabling the continuous loading operation.

The present invention as described above has the following advantages.

First, simply insert the sleeve into the loading unit and the device is taken out by the rail and automatically loaded into the socket of the burn-in board by the loading unit, thereby improving productivity by realizing the automation of the device.

Second, as the device is loaded into the socket of the burn-in board, the feed-in lead screw equipped with the burn-in board is automatically transferred by one step, thereby reducing the cycle time.

Third, the base and the elevating plate are guided and driven according to the shape in the cam groove due to the driving of the rotating plate to be made accurately.
