BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device loading apparatus, and more particularly, to a loading apparatus for loading a burned board to a burn-in board for a burn-in (BURM-IN) test of a manufactured device in a manufacturing process. The present invention relates to a device loading apparatus capable of improving the workability and productivity by loading a device of a device on a burn-in board that is stepped while being fixed and fixed to a board seat.

In general, a device manufactured in a manufacturing process is subjected to a burn-in test to determine whether or not it is suited to ambient conditions such as high temperature and withstand voltage. This is performed by inserting a plurality of devices into sockets on a systemized burn-in board according to a standard. Will be sent to the test line.

Such a device loading device includes a vacuum suction type loading device for inserting a device continuously supplied in a plurality of rows from a device supply device installed at an inclined angle to a socket of a burn-in board which is periodically moved by a head by vacuum suction and rotating and lifting operation; Finger type loading device is known which directly pulls out and inserts the device supplied from the device supply device by elevating operation while a plurality of sets of heads having a finger shape are angularly converted.

The vacuum suction type device loading device, which is an electronic device, is loaded with a separate conveying means in a state in which a sleeve containing a device is loaded, and the device contained in the sleeve has a certain angle (when the inclination angle of the rail is connected) Is supplied to the lower part of the rail and stopped at the end stop of the rail. As the device is loaded on the rail, the head is lowered and the vacuum pressure is generated through the vacuum hose. do.

After that, the head is raised to the initial state and rotated while being angularly converted to the burn-in board. Then, the head is inserted into the socket of the burn-in board, the head is reduced to the original situation, and the burn-in board is transported. It has a structure to be conveyed by one step.

However, the vacuum suction type loading device has a disadvantage of being entangled with each other due to gate marks generated during molding when the device on the rail is sucked up to the lowermost device. As a result, workability is deteriorated, which is a fundamental cause of poor connection.

Therefore, recently, as in the latter case, the finger loading device has been disclosed to allow the device to be connected to the burn-in board by converting the angle while the device is directly picked up by the finger robot hand. While the device has the advantage of solving the problem of the device being detached or disconnected from the connection by directly rotating the device, the operation speed is too slow and due to structural problems, There was still a concern about the connection, and the problem that the workability and productivity fell eventually remained.

The present invention has been made for the purpose of solving and improving all the problems of the prior art as described above.

The main object of the present invention is to change the angle of the device in a row in a state in which the finger-type head is ejected and raised at a time when the finger-type head is connected to the device repeatedly supplied in a plurality of rows by the device supply unit. It is to provide a device loading device that can be connected as it is to make the operation quick.

Another object of the present invention is to improve the structure of the head portion described above to enable perfect take-out and connection to double the workability and productivity.

Still another object of the present invention is to accurately seat the burn-in boards that are automatically supplied by the transfer device and to step-shift the device according to the connection operation of the device, thereby preventing the burn-in test failure of the device due to the poor connection.

In order to achieve the above object, in the present invention, the structure of the finger-type head is improved, and a plurality of the above-described finger heads are provided in the main head, which will become apparent when described in more detail according to the accompanying drawings.

That is, the present invention, as shown in Figures 1 to 6 of the accompanying drawings, the burn-in board loading portion 2 and the board transfer portion (3) for placing and placing the stacked board 21 in sequence and timing transfer; The board seating part 4 which corrects the conveyed burn-in board 21 in a correct position, and transfers it to a step, and the socket 22 of the burn-in board 21 which is step-feeded while seated in the board seating part 4 is carried out. The device loading part 6 which takes out and loads the device 51 supplied from the supply part 5 by a lifting operation and a rotating operation, and the conveying part 7 which removes and conveys the loaded burn-in board 21 are divided and mutually combined. Composed,

The device loading part 6 is axially coupled with the motor M1 of one side with the rotating plate 61 rotatably installed on the rotation shaft 62 at the upper middle portion of both side walls 60 constituting the main body,

In the middle of the rotating plate 61, the ball screw 64, which is installed at the lower part of the elevating plate 63 in order to elevate and is installed up and down, is axially coupled with the upper rotating motor M2.

In the lower inner side of the elevating plate 63, the main head 66, which is provided with a plurality of finger heads 65, which are held and released by the cylinders S1 and S2, is fixedly installed.

The finger head 65 is connected to a rod 67 and an air cylinder S1 fixed at an upper side of the cover 65a positioned at an inner lower side of a lower cover 65a, and in the middle of the gripper 65b. The insert tip 65c is connected to the rod 67a with another air cylinder S2 located on the other side of the upper portion, and a socket guide 65d is provided at the lower end of the cover 65a on the plurality of tanger springs 65e. It is possible to go up and down while being touched, but it is not detachable.

In addition, the above-described mounting portion 4 is provided with a plurality of detection sensors 41 so that the transported burn-in board 21 is fixed in accordance with the correct position.

Referring to the operation and the effect on the device of the present invention having such a structure as follows.

First, a plurality of burn-in boards 21 are stacked on the board loading section 2, and a device manufactured in a supply device such as a plurality of square guides (not shown) is placed in the device supply section 5 behind the loading section 6. In the inserted state, it is transferred according to the usual transfer method to maintain the operating standby state.

In this state, the operator operates the control system (not shown) to operate the lift lift (not shown) below the board stock unit 2 and to lift the burn-in board 21 that is raised by a separate moving device. When moving to the board transfer part 3 on the front side, the transfer of the burn-in board 21 by the conveyor system starts, and at the same time, the electric hoisting operation starts at the board storage part and maintains the standby state of the next operation. When the burn-in board 21 transferred by the board transfer unit 3 reaches the board seating unit 4, the burn-in board 21 is installed in the middle of the board seating unit 4 and is transported according to the rotation of the conveyor belt 42. 21 passes to the board seat 4.

As the transfer of the burn-in board 21 to the board seating part 4 progresses, a plurality of detection sensors 41 installed on the outer surface of the seating part 4 detect the moving position of the burn-in board 21 and reach the set position. If the transfer operation is suspended, the burn-in board 21 is clipped from the seating portion 4 to descend to a certain height and maintains the standby state of the step transfer operation by a separate drive source.

The device to be inserted 51 is inserted in the device supply section 5 behind the loading section 6 while maintaining the stand-by operation to the seating section 4 of the burn-in board 21 and the step feeding operation. When a plurality of rectangular guides 5 inserted in a row are raised one by one by a lifting lift to reach a supply position, the guide 5 is changed in an angle by a separate operating system and the front end is lowered. When descending, a plurality of devices 51 inserted therein are moved to the front side by their own weight, and the moved devices 51 are separately fixed and released by loading by a plurality of stoppers (not shown) at the bottom. The devices 21 supplied to the unit 6 are sequentially supplied one by one from the devices located below in the guide 5, which is made up of a plurality (8 to 10) of the guides 5. One bar Since they work together, the devices 51 supplied to the take-out position eventually form a row in the horizontal direction.

In this state, the loading unit 6 is operated by the operation of the timer device or the control system so as to load the devices 51 supplied in a row into the sockets 22 on the burn-in board 21 for step feeding.

At this time, the main head 66 having the finger-shaped head 65 at the end is lifted along the ball screw 64 by the operation of the upper motor M2, and the motor M1 on one side operates to rotate the rotating plate 61. ) Is rotated, so that the angle change is made at the same time as the finger head 65 is raised.

The change in the angle of the finger head 65 is located on the top of the device 51 at the end of the guide, which is the device supply section 5, as shown in the fourth drawing of the accompanying drawings, and the finger head ( As the cylinder S1 is lowered and the gripper 65b is expanded while the gripper 65b is lowered, the device that is waiting for supply is gripped at the upper and lower sides thereof, and the insert tip 65c is also held at the cylinder S2 to maintain the gripped state. It descends by operation, and takes out a gripping operation of a perfect device.

In this operation, a plurality of finger-type heads 65 are simultaneously operated to hold the waiting device 51 at a time, and the holding protrusions formed inside the lower end of the gripper 65b hold the device below. If the insert tip 65c is pressed against the upper surface of the lower surface, a perfect gripping effect is obtained, so that the pressed and fixed state can be firmly maintained regardless of the gate marks when the device 51 is formed, thereby the gripper 65b and the insert tip 65c. By this, the perfect gripping effect of the device 51 is obtained.

When the gripping operation of the device 51 is completed by such a series of operations, the finger-type head 65 rises to the state where the device is taken out and positioned, and is spaced apart from the device supply guide 5 so that the device 51 in the guide 5 is separated. ) Is lowered to the holding position by self-weight one by one and waiting to be taken out, and the raised finger-type head is converted to its original position by driving the motor M1 so that its position coincides with the socket 22 on the burn-in board 21. The finger-type head 65 is lowered as it is to load the device 51 into a plurality of sockets 22 formed on the burn-in board 21 at once.

At this time, when the finger-type head 65 is lowered, the head guide 65d, which is fixedly held by the finger spring 65e, coincides with the upper outer surface of the socket 22 of the burn-in board 21, and continues to descend. The compression force of the spring 65e is pushed by the lowering force of the spring, and the device 51 gripped by the gripper 65b and the insert tip 65c is inserted into the socket 22 and loaded according to the lowering motion. The gripper 65b of the finger-type head 65, which has been lowered after the device 51 has been loaded into the socket 22 of the burn-in board 21 by the operation, is enlarged by the operation of the cylinder S1, and the gripper is expanded. 65b rises as it is expanded through the gripper 65b separation space formed in the socket 22. As shown in FIG.

After the gripper 65b is raised, the burn-in board 21 moves forward one step, and the raised finger head 65 repeatedly performs the operation as described above, and the repeated operation of the finger head 65 is performed. In accordance with the burn-in board 21 also repeats the step transfer, the device 51 is all loaded quickly into the socket 22 of the burn-in board 21.

After the device 51 is completed loading on the burn-in board 21, the burn-in board 21, which has been stepped, is returned to its original position, is lifted while the clipping device (not shown) is released, and passes to the conveying unit by the conveyor belt.

Pass-in (burned) burn-in board 21 is moved to the conveying unit is sent to the test process for the burn-in test may be performed the following process.

According to the present invention, when a finger-type head takes out and loads a plurality of devices that are automatically repeatedly supplied in a plurality of rows by a device supply unit, a method of taking out and loading a row of devices at a time is selected. In addition, it is possible to expect a perfect and accurate gripping action by the improvement of the head structure, so that the working time is significantly reduced, there is a useful effect such as a significant improvement in the workability and productivity accordingly.
