The first lift frame 721 is coupled to the first lift rail 722 so as to be able to lift. The first lifting frame 721 can be divided into a first lifting portion 721a and a first converting portion 721b. Of course, the first elevating portion 721a and the first converting portion 721b may be integrally formed or integrally joined.

The first elevating portion 721a is a portion that is vertically coupled to the first elevating rail 722. A gripper 710 is coupled to the lower end of the first elevating portion 721a.

The first converting portion 721b has a first converting hole TH1 for converting the rotational force from the first power feeder 724 to a rising force. Here, a female screw acid is formed on the inner surface forming the first conversion hole TH1.

The first lift rail 722 is coupled to both the front and rear plates constituting the support frame 760 and guides the lifting and lowering of the first lift frame 721.

The first driving motor 723 is fixedly coupled to the support frame 760 and generates a driving force necessary for raising and lowering the first lift frame 721. The first drive motor 723 has a first drive pulley 723a that rotates according to an operation.

The first driven pulley 724a rotates in conjunction with the rotation of the first drive pulley 723a.

The first drive belt 724b rotates the first drive pulley 723a and the first driven pulley 723a as rotation turning points to interlock the first driven pulley 724a with the rotation of the first drive pulley 723a .

The first transmission shaft 724c rotates in conjunction with the rotation of the first driven pulley 724a. The first transmission shaft 724c is installed to pass through the first conversion hole TH1 and the upper end portion and the lower end portion are coupled to the support frame 760 rotatably by the bearing device BA. In the portion of the first transmission shaft 724c passing through the first conversion hole TH1, a male thread is formed and is screwed with the female thread of the first conversion hole TH1.

Accordingly, when the first drive motor 723 is operated to rotate the first drive pulley 723a, the first driven pulley 724a and the first transmission shaft 724c are rotated in conjunction with the rotation of the first drive pulley 723a And the first lift frame 721 moves up and down according to the rotation of the first transmission shaft 724c. As the first lifting frame 721 is lifted and lowered, the lifter 710 coupled to the first lifting frame 721 moves up and down. Of course, the stacking tray LT held by the gripper 710 also moves up and down together with the lifting and lowering of the gripper 710.

<Description of the presser>

The pusher 730 pushes the electronic part (not shown) loaded on the loading tray LT when the electronic part ED loaded on the loading tray LT and the test socket SK are electrically connected with the lowering of the gripper 710 ED so that the electronic component ED is electrically connected to the test socket SK. As shown in FIG. 13, these pushers 730 are provided in the same manner as the number of the electronic components ED loaded on the stacking tray LT, and are each provided with a pressing member 731, a static pressure cylinder 732, 733, and a coupling member 734.

The pressing member 731 presses down the electronic component ED while descending according to the operation of the second elevator 740 so that the electronic component ED is electrically connected to the test socket SK.

The static pressure cylinder 732 supports the pressing member 731 in a positive pressure so that the pressing member 731 can be moved up and down. For this purpose, the constant-pressure cylinder 732 maintains a constant pressure state by a constant-pressure regulator (not shown) provided separately from the connecting device 700.

The connecting member 733 connects the urging member 731 to the cylinder rod of the positive pressure cylinder 732 so that the urging member 731 can be positively supported by the positive pressure cylinder 732. [

The pusher 730 as described above descends together when the gripper 710 descends to electrically connect the electronic component ED to the test socket SK. 14, even if the stacking tray LT gripped by the gripper 710 is lowered and the electronic component ED loaded on the stacking tray LT contacts the test socket SK and an interference resistance is generated, The electronic component ED can be properly connected to the test socket SK since the pusher 730 presses the electronic component ED downward, which is the side of the test socket SK.

The positive pressure support of the pressure member 731 by the constant pressure cylinder 732 in the pressurizer 730 as described above has two functions. The first function is to check whether the electrical connection between the electronic component (ED) and the test socket (SK) is appropriate, and the second is a function to prevent the damage of the electronic component (ED) by the excessive pressing force .

On the other hand, the pressurizer 730 also functions as a departure prevention device for preventing the departure of the electronic component ED loaded on the stacking tray LT. For example, when the stacking tray LT is lifted or moved horizontally, the lower end of the pressing member 731 is positioned at a position (as shown in Fig. 15) in a state in which a minute gap with the electronic component ED loaded on the stacking tray LT is maintained, So that it is possible to prevent the electronic component ED from deviating from the correct position. In view of the function of preventing the detachment of such an electronic component ED, the pusher 730 is also capable of preventing the deterioration of the electronic component ED when the electronic component ED and the test socket SK are electrically connected or disconnected It can be considered to perform the function of preventing the deviation of the electronic part ED from the correct position.

&Lt; Description of the second elevator >

The second lift frame 741 can be divided into a second lift portion 741a and a second change portion 741b. Of course, the second lift portion 741a and the second conversion portion 741b may be integrally formed or combined.

The second lift portion 741a is a portion where the second lift rail 742 is fixed. 17, the static pressure cylinder 732 of the pressurizer 730 is fixed to the lower portion of the second lift portion 741a by the engaging member 734. As shown in Fig.

The second converting portion 741b has a second converting hole TH2 (see the drawing portion) for converting the rotational force from the second power feeder 744 into a rising force. Here, a female screw acid is formed on the inner surface forming the second conversion hole TH2. The second conversion portion 741b also serves to couple the second lift portions 741a spaced apart from each other in the front-rear direction.

The four second elevating rails 742 are fixed to the second elevating portion 741a of the second elevating frame 741 and are elevatably coupled to a rail block RB fixed to the supporting frame 760 . That is, the rail block RB fixed to the support frame 760 is not moved in the vertical direction, but is a coupling structure in which the four second lift rails 742 are raised and lowered.

The second driving motor 743 is fixedly coupled to the mounting plate 761 of the support frame 760 and generates a driving force necessary for raising and lowering the second lift frame 741. The second drive motor 743 has a second drive pulley 743a that rotates according to the operation.

The second driven pulley 744a rotates in conjunction with the rotation of the second drive pulley 743a.

The second driven belt 744b rotates the second driven pulley 743a and the second driven pulley 744a as rotation turning points to interlock the second driven pulley 744a with the rotation of the second drive pulley 743a .

The second transmission shaft 744c rotates in conjunction with the rotation of the second driven pulley 744a. The second transmission shaft 744c is installed to pass through the second conversion hole TH1 and the upper end portion and the lower end portion are coupled to the mounting plate 761 side rotatably by the bearing device BA. The portion of the second transmission shaft 744c passing through the second conversion hole TH2 is formed with a male thread and is screwed with the female thread of the second conversion hole TH2.

Accordingly, when the second drive motor 743 is operated to rotate the second drive pulley 743a, the second driven pulley 744a and the second transmission shaft 744c are rotated in conjunction with the rotation of the second drive pulley 743a And the second lift frame 741 moves up and down according to the rotation of the second transmission shaft 744c. As the second lift frame 741 is lifted and lowered, the sixteen pushers 730 coupled to the second lift frame 741 move up and down.

<Explanation of checker>

The checker 750 is electrically connected to the electronic component ED and the test socket SK when the electronic component ED and the test socket SK are electrically connected to each other along with the lowering of the gripper 710. [ SK). This confirmation device 750 includes a confirmation element 751 fixed to the static pressure cylinder 732 of the pusher 730 and a confirmation element 752 fixed to the pushing member 731 of the pusher 730 as shown in Fig. .

The confirmation element 751 detects and confirms the confirmed element 752 through light emission and light reception (see arrow A) as in FIG. In this embodiment, when the confirmation element 751 senses the component to be confirmed 752, the connection between the electronic component ED and the test socket SK is not properly performed, and when the confirmation element 751 If the electronic component ED and the test socket SK are properly connected in the case where the component to be confirmed 752 is not sensed.

20 (a), if the terminal portion of the electronic component ED loaded on the stacking tray LT is not properly inserted into the slot of the test socket SK, The urging member 731 is relatively urged upward. Therefore, the pressing member 731 is in a state of relatively rising with respect to the descending static pressure cylinder 732 while the descending is stopped in spite of the descent of the static pressure cylinder 732. [ In this case, the component to be confirmed 752 fixed to the pressing member 731 is also relatively higher than the confirmation component 731 fixed to the static pressure cylinder 732. Thus, the acknowledgment element 731 senses the acknowledgment element, indicating that the connection between the electronic component (ED) and the test socket (SK) is not properly established. Of course, when the connection between the electronic component ED and the test socket SK is properly performed as shown in FIG. 20 (b), the confirmation element 751 can not detect the confirmed element 752.

Meanwhile, FIG. 21 is a conceptual left side view for roughly grasping the layout structure of each of the components constituting the above-described connecting device 700. That is, the first lift frame 721 is coupled to the outside of the support frame 760 such that the second lift frame 741 is vertically coupled to the inside of the support frame 760. As described above, the gripper 710 is coupled to the first lift frame 721 to move up and down together with the first lift frame 721, and the presser 730 is coupled to the second lift frame 741, And moves up and down together with the lift frame 741. Of course, since the checker 750 is coupled to the pressurizer 730, the ascending and descending of the second lift frame 741 occurs.

<Explanation of the overall operation of the connection device>

When the loading tray LT on which the electronic part ED is loaded is located at the loading position IP, the connecting device 700 moves to the loading position IP and grips the loading tray LT. That is, the first elevator 720 is operated to lower the gripper 710, and the driving source 712 operates to hold the holding tray LT by the gripper 710. Then, the first elevator 720 is operated to raise the gripper 710. At this time, the gripper 710 has only a small gap between the upper end of the electronic part ED and the lower end of the urging part 731 so that the electronic part ED loaded on the stacking tray LT is lifted or lowered, So that it can be prevented from being detached from the correct position. Of course, when the standard of the electronic part ED to be tested is changed, the height of the gripper 710 can be set in accordance with the standard of the changed electronic part ED.

When the gripper 710 is raised, the connecting device 700 is moved to the test position TP by the horizontal rail HR and the belt device BA. Of course, the socket board SB of the tester TESTER is located below the test position TP. Therefore, when the connecting device 700 is moved to the test position TP, the first elevator 720 and the second elevator 740 operate to lower the gripper 710 and the pressurizer 730.

The stacking tray LT is lowered by the lowering of the gripper 710 and the stacking tray LT and the socket board SB are matched by the interaction of the matching holes LH and the matching pins LP. The position of the electronic component ED is aligned by the interaction of the guide holes GH ₁ and GH ₂ and the alignment pins AP ₁ and AP ₂ so that the terminal portion of the electronic component ED is aligned with the position of the test socket SK Slot. Then, the electronic component ED and the test socket SK are electrically connected to each other.

At this time, whether or not an appropriate connection between the electronic component (ED) and the test socket (SK) is confirmed by the checker (750).

The first elevator 720 and the second elevator 740 are operated and the gripper 710 and the pusher 730 are moved up, So that the stacking tray LT is raised.

When the gripper 710 is lifted, the connecting device 700 horizontally moves to the carry-out position OP. After releasing the gripper 710, the gripping of the stacking tray LT is released.

In the description of the above process, it is described that the connecting device 700 keeps gripping the stacking tray LT at the time of testing the electronic component ED. However, when the electronic component ED is tested, the connecting device 700 Can perform a moving operation or the like on the other stacking tray LT.

The connecting device 700 according to the present invention can move the loading tray LT between the loading position IP and the unloading position OP while moving the loading tray LT between the loading position IP and the unloading position OP, And connects the electronic component ED in the state of being loaded in the stacking frame LT at the test position TP between the test socket SK and the test socket SK.

As described above, the present invention has been described in detail with reference to the accompanying drawings. However, the above-described embodiments have been described with reference to preferred embodiments of the present invention. Accordingly, the present invention should not be construed as being limited to the above-described embodiments, and the scope of the present invention should be understood as the following claims and their equivalents.
