For example, as shown in Figs. 14 to 17, in order to move the element pressing tools 830 and 840 in the horizontal direction (Y-axis direction) A first vertical moving device 802 is provided which is connected to the device pressing tools 830 and 840 in order to move the device pressing tools 830 and 840 in the vertical direction (Z-axis direction) do.

The horizontal movement device 801 includes a connection member 830a and 840a extending in the vertical direction from the element pressing tools 830 and 840 and connected to the vertical movement direction of the support shafts 830a and 840a, And 840b and a horizontal driving unit 803 for moving the connecting members 830b and 840b in the horizontal direction.

The support shafts 830a and 840a are formed in the connection members 830b and 840b so as to be vertically penetrated and connected to the connection members 830b and 840b so that the movement of the support shafts 830a and 840a in the horizontal direction is restricted, Through holes 830c and 840c into which the shafts 830a and 840a are inserted can be formed. As the supporting shafts 830a and 840a are inserted into the through holes 830c and 840c of the connecting members 830b and 840b, the horizontal movement of the supporting shafts 830a and 840a is transmitted to the connecting members 830b and 840b But the movement of the support shafts 830a and 840a in the vertical direction is not constrained. The through holes 830c and 840c can also serve to guide the movement of the support shafts 830a and 840a in the vertical direction.

The horizontal driving unit 803 includes a belt 803a connected to the connecting members 830b and 840b, a pulley 803b around which the belt 803a is wound, a rotary motor 803b connected to the pulley 803b Not shown). According to such a construction, the pulley 803b is rotated by the rotational force of the rotation motor (not shown), and the connecting members 830b and 840b connected to the belt 803a and the belt 803a by the rotation of the pulley 803b, The supporting shafts 830a and 840a and the element pressing tools 830 and 840 connected to the connecting members 830b and 840b can be moved in the horizontal direction. In the embodiment of the present invention, the horizontal driving unit 803 is provided with the belt 803a and the pulley 803b. However, the present invention is not limited thereto. The horizontal driving unit 803 may be a hydraulic or pneumatic A variety of horizontal transport mechanisms may be used, including actuated actuators, linear motors or ballscrew devices.

In the first vertical movement device 802, the vertical movements of the support shafts 830a and 840a extending in the vertical direction from the element pressing tools 830 and 840 are constrained and connected to be movable in the horizontal direction The cam followers 830e and 840e connected to the moving blocks 830d and 840d and the cam members 830f and 840f in which the cam followers 830e and 840e are inserted are formed 830g and 840g connected to the moving blocks 830d and 840d and elevation guides 830h and 840h for guiding movement of the moving blocks 830d and 840d in the vertical direction.

Guide rods 830i and 840i are connected to the end portions of the support shafts 830a and 840a and extend in the horizontal direction to guide the movement of the support shafts 830a and 840a in the horizontal direction . Thus, the support shafts 830a and 840a can be moved in the horizontal direction along the guide rails 830i and 840i.

Driving motors 830j and 840j are connected to the cam members 830g and 840g so that the cam members 830g and 840g can be rotated by driving the driving motors 830j and 840j. The cam members 830g and 840g may be provided in pairs so as to be connected to the pair of element pressing tools 830 and 840, respectively.

The cam grooves 830f and 840f are formed to include a first radius section and a second radius section having a constant radius and a variable section connecting the first radius section and the second radius section. When the cam grooves 830f and 840f are configured as described above, the element pressing tools 830 and 840 are positioned on the upper side when the cam yarn movements 830e and 840e are in the first radius section having a small radius, The device pressing tools 830 and 840 are moved upward or downward when the moving cam followers 830e and 840e are in the variable section and the moving speed of the moving cam followers 830e and 840e is larger than that of the second The element pressing tools 830 and 840 are kept in a lower position.

The moving blocks 830d and 840d can be connected to the cam members 830g and 840g through insertion of the cam followers 830e and 840e into the cam grooves 830f and 840f. The moving blocks 830d and 840d are connected to the elevation guides 830h and 840h and can move up and down in the vertical direction. Therefore, when the cam members 830g and 840g are rotated, the cam followers 830e and 840e move in the vertical direction in accordance with the shapes of the cam grooves 830f and 840f, and thus are connected to the cam followers 830e and 840e The movable blocks 830d and 840d can be moved in the vertical direction and the element pressing tools 830 and 840 connected to the movable blocks 830d and 840d and the supporting shafts 830a and 840a can be moved in the vertical direction .

The elevation guides 830h and 840h can be fixed to the fixture 804 provided at the upper portion of the movable blocks 830d and 840d. However, the present invention is not limited to this, and various configurations can be used as the elevation guides 830h and 840h as long as they can guide the elevating and lowering of the moving blocks 830d and 840d.

According to such a configuration, the element pressing tools 830 and 840 are moved in the horizontal direction by the horizontal moving device 801, and thereby, between the first shuttle part 610 and the test socket 310, The element pressing tools 830 and 840 can be moved in the horizontal direction between the shuttle part 620 and the test socket 310. [ The element pressing tools 830 and 840 are vertically moved by the first vertical movement device 802 to the upper portion of the first shuttle portion 610 and the upper portion of the second shuttle portion 620 and the upper portion of the test socket 310, The element 1 can be picked up or the element 1 can be loaded. These element pressing tools 830 and 840 move vertically at the top of the test socket 310 to move the element 1 to the test socket 310 in order to firmly couple the element 1 to the test socket 310 It is possible to perform the function of pressing with a constant force.

As described above, since the element pressing tools 830 and 840 are moved in the vertical direction in accordance with the rotation of the cam members 830g and 840g, the moving position of the element pressing tools 830 and 840 in the vertical direction can be accurately set .

Also, in the process of the test of the device 1 being pressed by the test socket 310, the pressurized state of the device 1 with respect to the test socket 310 must be maintained for a predetermined time. For this purpose, when only a linear movement motor such as a rotary motor or a linear motor of the ball screw device is used without using the cam members 830g and 840g, a relatively large voltage for pressing the element 1 is continuously applied to the linear movement motor The pressing force of the element 1 with respect to the test socket 310 is applied to the driving motors 830j and 840j when the cam members 830g and 840g are used Irrespective of changes in the voltage applied to the cam members 830g and 840g. Therefore, when the first vertical movement device 802 for moving the element pressing tools 830 and 840 in the vertical direction includes the cam members 830g and 840g, the cam members 830g and 840g are used There is an effect that the energy can be saved as compared with the case where only the linear movement motor is used.

On the other hand, depending on the type of the device 1 to be tested or the type of the test socket 310 so that the device 1 can be precisely pressed to the test socket 310 so that the test on the device 1 can be accurately performed, The pressing position at which the pickers 831 and 841 of the tools 830 and 840 are to be positioned can be changed. It is also necessary to check and check whether the element pressing tools 830 and 840 are accurately lowered to the pressing position and press the element 1 to the test socket 310. [

Accordingly, in order to change or confirm the pressing position of the element pressing tools 830 and 840, the horizontal moving device 801 and the first vertical moving device 802 connected to the element pressing tools 830 and 840 are moved up and down It is necessary to determine whether or not the pressing positions of the element pressing tools 830 and 840 are to be set at the pressing position, that is, the reference position, by rotating the cam members 830g and 840g.

8 and 9, a horizontal moving device 801, and a first vertical moving device 802, as shown in FIGS. 18 and 19, for the device testing apparatus according to the embodiment of the present invention. A second vertical movement device 805 for moving the element pressing part linearly in the vertical direction by being connected to the pressing part and a second vertical movement device 805 for moving the element pressing tools 830 and 840 by the second vertical movement device 805, 830 when the detected load reaches a preset reference load, and detects the load applied to the test part 300 by the second vertical movement device 805 when the load is applied to the test tool 300. [ And a control unit 807 for determining the position of the pressing position as a pressing position.

The second vertical movement device 805 may also be connected to the first vertical movement device 802 and the horizontal movement device 801 and in this case the first vertical movement device 802 and the horizontal movement device 801 may be connected together And can be raised and lowered by the second vertical movement device 805, whereby the element pressing tools 830 and 840 can be raised and lowered.

The portions of the element pressing tools 830 and 840 which contact the test portion 300 are positioned on the lower sides of the picker modules 834 and 844 located around the pickers 831 and 841, As shown in Fig. To this end, a portion of the lower side of the pick ground blocks 836 and 846, which is in contact with the test portion 300, may be made of a metal such as aluminum.

The portion where the element pressing tools 830 and 840 contact with the test portion 300 may be the upper surface of the support frame 312 supporting the test socket 310. For this, the portion of the upper surface of the support frame 312 where the element pressing tools 830 and 840 are contacted may be made of a metal such as aluminum. The element pressing tools 830 and 840 are pressed while the lower side of the picker modules 834 and 844 is in contact with the upper surface of the support frame 312 in the process of pressing the element 1 to the test socket 310, The pressing position of the element 1 with respect to the test socket 310 is determined.

Therefore, when the height of the support frame 312 varies depending on the type of the element 1, the type of the test socket 310, or the type of the terminal 311 provided in the test socket 310, It can be determined whether or not the element 1 is located at the pressing position by judging whether or not the lower surface of the element pressing tools 830 and 840 is in contact with the upper surface of the support frame 312. [

For this purpose, it is possible to consider a method of providing a sensor for detecting whether the lower side of the element pressing tool 830 is in contact with the upper surface of the support frame 312. However, in such a case, There is a problem in that the configuration of the element pressing tools 830 and 840 and the test socket 310 becomes complicated when considering the installation position of the sensor and the like.

Therefore, when the element pressing tools 830 and 840 are brought into contact with the test portion 300, the change amount of the load of the second vertical movement device 805 is sensed, and the test portion 300, And a control unit 807 for determining the position of the element pressing tools 830 and 840 as a pressing position when the detected load reaches a preset reference load.

When the second vertical movement device 805 is a belt conveyance mechanism that is connected to the ball screw device including the motor 806 or the motor 806 through a pulley, Similarly, it can be connected to the motor 806 to sense a load such as the torque of the motor 806. When the element pressing tools 830 and 840 are lowered by the second vertical movement device 805 in a state where the element pressing tools 830 and 840 are not in contact with the test portion 300, The amount of change in the load of the motor 806 sensed by the controller 807 is not large. However, when the element pressing tools 830 and 840 contact the test unit 300, the load sensed by the controller 807 increases. The controller 807 senses the load of the motor 806 and uses the sensed load to move the second vertical movement device 805 when the element pressing tools 830 and 840 are in contact with the test portion 300. [ And the position of the element pressing tools 830 and 840 when the detected load reaches a preset reference load is determined as the pressing position.

As another example, when the second vertical movement device 805 is a linear motor that operates using electromagnetic interaction between the permanent magnet and the electromagnet, the control unit 807 can be configured to sense the load of the linear motor.

Hereinafter, a method of setting the pressing positions of the element pressing tools 830 and 840 using the above-described configuration will be described.

First, the first element pressing tool 830 of the element pressing tools 830 and 840 is positioned on the upper portion of the test portion 300 having a predetermined height, that is, the upper portion of the support frame 312, The first element pressing tool 830 is positioned at the lowest position where the first element pressing tool 830 can be lowered by the rotation of the cam member 830a by rotating the cam member 830g connected to the pressing tool 830 .

Then, the second vertical movement device 805 is operated to gradually lower the element pressing portion 830 while gradually lowering the element pressing portion 830. At the same time, the control unit 807 detects the load applied to the test unit 300 by the first element pressing tool 830 through sensing the load of the second vertical movement unit 805.

18 and 19, as the first element pressing tool 830 is lowered by the second vertical movement device 805, the first element pressing tool 830 contacts the test portion 300 , Whereby the load applied to the test portion 300 by the first element pressing tool 830 is changed. At this time, when the load applied to the test unit 300 by the first element pressing tool 830 becomes the reference load, the control unit 807 determines that the position of the first element pressing tool 830 coincides with the preset pressing position And the operation of the second vertical movement device 805 is stopped.

After completing the process of setting the pressing position of the first element pressing tool 830 as described above, the process of setting the pressing position of the second element pressing tool 840 is performed by the first element pressing tool 830, In the same manner as in the process of setting the pressing position of the pressing member.

When the pressing position of the element pressing tools 830 and 840 is set through the above process, the pressing force of the element 1 pushing the element 1 to the test socket 310 by the element pressing tools 830 and 840 The test procedure can be performed.

When it is necessary to adjust the pressing position of the element pressing tools 830 and 840 according to the type of the element 1 or the type of the test socket 310, Alternatively, if it is necessary to confirm and check whether the element pressing tools 830 and 840 are correctly lowered to the pressing position and press the element 1 to the test socket 310, the second vertical movement device 805, The device pressing tools 830 and 840 are lowered to be in contact with the test portion 300 and the load of the second vertical movement device 805 is sensed and the test load is applied to the test portion 300 The pressing position of the element pressing tools 830 and 840 is determined as the pressing position by determining the position of the element pressing tools 830 and 840 when the detected load becomes the preset reference load It can be determined easily and accurately.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
