Hereinafter, the arrangement relationship of the first slide connection part 230 , the 2-1 slide connection part 251 , and the 2-2 slide connection part 252 will be described in detail.

Each of the first slide connection part 230, the 2-1 slide connection part 251, and the 2-2 slide connection part 252 is connected to each of the first and second rails 110 and 120 through a bearing provided therein. It may be an LM guide.

The aforementioned first slide connection part 230 , the 2-1 slide connection part 251 , and the 2-2 slide connection part 252 have the same shape. Accordingly, the friction coefficient of the portion (eg, a bearing in the case of an LM guide) where the first slide connection part 230 and the first rail 110 are connected, the 2-1 slide connection part 251 and the second rail 120 ) The friction coefficient of the connected part (eg, a bearing in the case of an LM guide) and the friction of the part (eg, a bearing in the case of an LM guide) where the 2-2 slide connection part 252 and the second rail 120 are connected The coefficients are all the same.

In the first slide connection part 230 , the 2-1 slide connection part 251 , and the 2-2 slide connection part 252 , the center point C1 of the first slide connection part 230 is the 2-1 slide connection part 251 . ) of the central point C2 and the center point C3 of the 2-2 slide connection part 252 are arranged to be located in the center of the front-rear direction.

In detail, as the cylinder 300 is connected to the right body 212 of the body 210 of the slide block 200 , when the cylinder 300 expands and contracts, a force is applied to the right side of the slide block 200 . will lose Accordingly, when the slide block 200 moves forward and backward, a yaw phenomenon occurs in which the slide block 200 is shaken. However, as in the present invention, two slide connection parts, that is, the 2-1 slide connection part 251 and the 2-2 slide connection part 252 are provided on the right body 212 to which the cylinder 300 is connected, and the cylinder As one slide connection part, that is, the first slide connection part 230 is provided on the left body 211 to which 300 is not connected, a higher friction force is generated between the right body 212 and the second rail 120 . (As described above, since the friction coefficients of all the slide connections are the same, the frictional force generated in the right body 212 and the second rail 120 is the same as the frictional force generated in the left body 211 and the first rail 110 . 2 times) to effectively prevent the above yaw phenomenon.

In addition, in the first slide connection part 230 , the 2-1 slide connection part 251 , and the 2-2 slide connection part 252 , the center point C1 of the first slide connection part 230 is the 2-1 slide connection part Since the center point C2 of 251 and the center point C3 of the second-second slide connection part 252 are located in the front-rear center, the yaw phenomenon can be more effectively prevented.

As the yaw phenomenon is prevented as described above, when the pressing unit 710 presses the terminal portion of the electronic component, the alignment of the electronic component is not disturbed, and thus, the terminal portion and the connection portion 480 are accurately connected. Accordingly, the socket 10 for testing electronic components has high test accuracy.

As shown in FIG. 3C , when the pressing unit 710 of the elevating block 700 descends and presses the terminal of the electronic component, the pressing unit 710 is fixed to the seating unit 410 of the electronic component. The phosphorus fixing part is positioned within a range from the front end of the 2-1 slide connecting part 251 to the rear end of the 2-2 slide connecting part 252 .

As described above, as the fixed portion of the electronic component is positioned within the above range, the alignment of the fixed portion of the electronic component is disturbed by shaking generated according to the slide of the slide block 200 or the lowering of the elevating block 700. Accordingly, it is possible to effectively prevent the connection portion 480 from being properly connected to the terminal portion of the electronic component.

This is within the range where the first slide connection part 230, the 2-1 slide connection part 251, and the 2-2 slide connection part 252 are located in the slide block 200, the first slide connection part 230, the second Since the 2-1 slide connection part 251 and the 2-2 slide connection part 252 support the slide block 200, the shaking generated according to the slide of the slide block 200 or the descent of the elevating block 700 This is because it is not transmitted. That is, shaking does not occur within the range in which the first slide connection part 230, the 2-1 slide connection part 251, and the 2-2 slide connection part 252 are supported, so that the alignment of the electronic components is disturbed. This is prevented, and through this, the test reliability of the socket 10 for testing electronic components can be improved.

As described above, in the socket 10 for testing electronic components of the present invention, after the electronic components are transferred by the robot arm and fixed to the seating unit 410, the slide block 200 slides forward, and then the elevating block ( 700) descends to pressurize the terminal portion of the electronic component, thereby electrically connecting the terminal portion and the connecting portion 480 of the electronic component. Thereafter, the electronic component and the test PCB 470 are electrically connected to test the electronic component.

When the test of the electronic component is completed, the elevating block 700 rises to release the connection between the terminal portion and the connection portion 480 of the electronic component, and after the slide block 200 slides backward, the robot arm mounts the electronic component It will be picked up from the unit 410 .

As described above, through the socket 10 for testing electronic components of the present invention, it is possible to automatically achieve testing of electronic components.

Hereinafter, the seating block 400 will be described.

1 and 4 , the seating block 400 is installed on the upper surface of the base 100 to be positioned between the first and second rails 110 and 120 .

The seating block 400 includes a seating part 410 on which the electronic component to be tested is mounted; a test PCB 470; and a connection part connected to the terminal part of the electronic component to electrically connect the terminal part and the test PCB 470 (480); may be configured to include.

The seating part 410 functions to provide a space in which the electronic component to be tested is mounted.

The seating portion 410 includes a seating plate 420 on which the electronic component to be tested is mounted; and the front and left sides of the fixing portion (not shown), which is a portion fixed to the seating portion 410 among the electronic components to be tested. A first support part 430 for aligning the fixed part by contacting; and a second support part 440 which aligns the fixed part in contact with the rear and right sides of the fixed part, and is provided to be tiltable; may be configured to include there is.

The seating plate 420 provides a space in which the electronic component to be tested is mounted.

The fixing portion of the electronic component to be tested, the terminal portion of the electronic component, and a connection portion (not shown) connecting the fixing portion and the terminal portion are all seated on the seating plate 420 . In this case, the connection part may be a non-fixed part that is not fixed to the seating part 410 among the electronic components to be tested. For example, the connection part, ie, the non-fixed part, is made of a flexible material that can be bent, such as an electric wire and a flexible PCB, and can function to electrically connect the terminal part and the fixed part.

The first support part 430 is fixedly installed and disposed in front of the seating plate 420 .

The first support part 430 has a '┏' shape as a whole so that its inner surface can contact the front and left surfaces of the fixing part.

Therefore, when the electronic component is seated on the seating plate 420 , the inner surface of the first support part 430 contacts the front and left surfaces of the fixing part of the electronic component, thereby fixing the fixing part to secure the fixing part of the electronic component. It functions to sort.

The support member 443 of the second support part 440 corresponds to the first support part 430 , and has a '┛' shape as a whole so that an inner surface thereof can contact the rear surface and the right surface of the fixing part.

Accordingly, when the electronic component is seated on the mounting plate 420 , the inner surface of the support member 443 of the second support unit 440 contacts the rear and right sides of the fixing portion of the electronic component, thereby fixing the electronic component and fixing the electronic component. It functions to align the fixed parts of the parts.

Unlike the first support part 430 , the support member 443 of the second support part 440 is tiltably installed on the seating plate 420 .

The second support part 440 is, as shown in FIGS. 5 to 7B, a slide plate 441 that is slidably installed in the front-rear direction; and one end is connected to the rear of the slide plate 441, and the other end is A first elastic member 444 connected to the rear of the seating part 410; and a rotation shaft 442 installed on the slide plate 441; and a rotation shaft 442 to be able to tilt around the rotation shaft 442. and a support member 443 installed on the slide plate 441 by It may be configured to include a second elastic member (445).

The second support part 440 slides the slide plate 441 forward by pushing the slide plate 441 by a pressing member (not shown) provided on the lower surface of the pressing part 710 when the pressing part 710 descends. And, when the pressing part 710 rises, the slide plate 441 is slid backward by the elastic restoring force of the first elastic member 444 to return to the original position.

In detail, as shown in FIG. 7A , the second support part 440 as above maintains the slide plate 441 completely slid backward due to the elastic restoring force of the first elastic member 444 . do.

Thereafter, as shown in FIG. 3c , the slide block 200 slides completely forward, and the elevating block 700 descends, and when the pressing unit 710 descends, the lower surface of the pressing unit 710 . The pressing member protruding in the downward direction is inserted into the space between the slide plate 441 and the rear of the seating part 410 .

After that, as the pressing unit 710 descends, the pressing member pushes the rear of the slide plate 441 to slide the slide plate 441 forward.

As described above, as the slide plate 441 slides forward, the rear surface and the right surface of the fixing part of the electronic component are fixed and aligned by the support member 443 .

In other words, as the slide plate 441 slides forward, it comes into contact with the front and left surfaces of the fixing part of the electronic component by the first support part 430 , and the electronic part is moved by the second support part 440 by the second support part 440 . As the rear surface and the right side of the fixing part come into contact, the fixing part of the electronic component is firmly fixed.

After the test of the electronic component is performed, when the elevating block 700 rises and the pressurizing unit 710 rises, the pressurization by the pressurizing member is released, so the slide plate 441 is a first elastic member 444 . It slides backward by the elastic restoring force of

The rotating shaft 442 is installed in the protruding front of the slide plate 441 . The support member 443 is installed on the rotation shaft 442 so as to be able to tilt around the rotation shaft 442 .

The support member 443 corresponds to the first support part 430 , and has a '┛' shape as a whole so that its inner surface can contact the rear surface and the right surface of the fixing part.

On the inner surface of the support member 443, a first bearing 448 that is in contact with the right side of the fixed part of the electronic component and can rotate by itself, and a second bearing 449 that can rotate by itself while in contact with the rear surface of a predetermined part of the electronic component. this is provided In detail, a first bearing 448 is provided on an inner surface of the inner surface of the support member 443 in contact with the right surface of the fixing part of the electronic component, and after the fixing member of the electronic component among the inner surface of the support member 443 . A second bearing 449 is provided on the inner surface in contact with the surface.

Each of the first bearing 448 and the second bearing 449 is installed on the support member 443 by an axis, and therefore, each of the first bearing 448 and the second bearing 449 can rotate by itself. .

Therefore, when the slide plate 441 is slid forward by the pressing member of the pressing part 710, the first bearing 448 rotates in contact with the right side of the fixing part of the electronic component, so that the first bearing 448 is Since it acts as a kind of wheel, the slide plate 441 slides forward more smoothly and at the same time, damage to electronic components can be prevented.

An elastic material such as rubber may be formed on the outer peripheral surfaces of the first bearing 448 and the second bearing 449 . Accordingly, in the first bearing 448 and the second bearing 449 , the slide plate 441 slides forward by the elastic force of the first elastic member 444 , and the support member 443 is the fixed portion of the electronic component. When a force is applied to the rear surface and the right surface, it can function to prevent the fixing part of the electronic component from being damaged.

In addition, one end of the second elastic member 445 is connected to one side, that is, the rear surface of the support member 443 , and the other end of the second elastic member 445 is a second elastic member connecting portion of the slide plate 441 . It is connected to (447).

The second elastic member 445 applies an elastic force to the support member 443 when the support member 443 is tilted about the rotation shaft 442 , thereby preventing damage to the fixed portion of the electronic component and the fixed portion of the electronic component. It functions to make the fixation of the

As described above, the seating part 410 firmly fixes the fixing part of the electronic component through the first support part 430 and the second support part 440 . Therefore, when the pressing part 710 presses the terminal part, it prevents the electronic part from being disturbed, thereby preventing malfunction of the electronic part test from occurring due to a connection error between the terminal part and the connection part 480 in advance. there is.

In addition, as the slide plate 441 slides forward in association with the pressing unit 710 of the elevating block 700, it is possible to align and fix electronic products of various sizes without error.

In detail, when the slide distance of the slide plate 441 is set and there is an error in the size of the electronic product, it is impossible to firmly fix the slide plate 441 by the first and second support parts 430 and 440 . In addition, as the types of electronic products change, it is cumbersome to have to set the slide distance one by one. However, in the case of the present invention, until the fixing part of the electronic product is completely fixed, the slide plate 441 is mechanically sliding forward in conjunction with the descent of the pressing part 710, even if an error in the size of the electronic product occurs The fixed part of the electronic product can be completely fixed, and various types of electronic products can be fixed and aligned without setting a separate slide setting value.

Hereinafter, the test PCB 470 and the connection unit 480 will be described in detail.

As described above, the terminal unit is connected to the protruding contact pin 481 , and through this, the electronic component and the test PCB 470 are electrically connected, and the electronic component is tested.

After the test of the electronic component is performed, when the elevating block 700 rises, the pressurization of the terminal unit by the pressing unit 710 is released. Accordingly, the elevating portion 482 is raised by the third elastic member 485, and the contact pin 481 is not inserted into the hole 483 and does not protrude upward, so the contact pin 481 and the electronic component The terminal part is disconnected.
