Description

Transfer and test handler including it {TRANSFER AND TEST HANDLER INCLUDING SAME}

The present invention relates to a transfer and a test handler including the same.

In general, electronic parts are distributed on the market after passing tests such as durability and defect detection. To test these electronic components, a tester for testing electrically connected electronic components and a test handler, which is a device for electrically connecting the electronic components to the tester, are required.

The test handler uses a test tray that can be transported all at once in a state where a large number of electronic components are loaded in a matrix form to increase the test throughput. The electronic component is electrically connected to a test socket of the tester in a state of being loaded on the test tray, and the test is performed.

Electronic components to be tested are loaded on a customer tray. The customer tray serves to load and store electronic components. The untested electronic components loaded on the customer tray are transferred to the test tray, or the tested electronic components loaded on the test tray are loaded onto the customer tray.

In general, a plurality of pockets are arranged in the customer tray for independently loading and arranging a plurality of electronic components. When such a number of electronic components are loaded on the customer tray, a pocket rib phenomenon may occur. The pocket rib phenomenon refers to a phenomenon in which some electronic parts among a plurality of electronic parts are not completely seated in pockets on the customer tray, and some are not normally seated in pockets, such as hanging over the outer edge of pockets.

When the customer tray is transported while the electronic component is pocket ribbed, there is a problem in that the electronic component is damaged while the customer tray is transported. In addition, when the pocket ribbed electronic component is gripped to be transferred to the test tray, there is a problem in that it is not normally gripped. In this way, when the electronic component is transferred onto the test tray in a state in which it is not normally gripped, cracks occur in the electronic component, damage occurs to the terminal of the electronic component, and a problem occurs in identification of the electronic component.

Conventional transfers are manufactured to have a vibration motor for applying vibration to the customer tray so that the electronic part placed on the customer tray is completely seated in the pocket in order to prevent the pocket rib phenomenon of the electronic part. The vibration motor is coupled to the set plate of the transfer to apply vibration to the set plate, and the vibration applied to the set plate may indirectly vibrate the customer tray. On the other hand, there is a problem in that the pocket rib phenomenon of the electronic component cannot be completely solved only by the vibration force applied to the set plate by the conventional vibration motor. When the size of the vibration motor is increased to increase the size of the vibration motor to increase the vibration force, there is a problem in that the space utilization is lowered and the fastening force between the vibration motor and the set plate is weakened due to the increase in the weight of the vibration motor. . In addition, there is a problem in that a lot of cost is consumed in order to provide a vibration motor having high performance capable of increasing the vibration force without increasing the size of the vibration motor.

Referring back to FIG. 12 , the spacer 130 may separate the tray support 110 by the first distance h1 when the vibration transmission body 100 is seated in the seating groove 211 . The spaced portion 130 may have a predetermined thickness h1. In addition, the spacer 130 may come into contact with the set plate 200 when the vibration transmission body 100 is seated in the seating groove 211 . For example, when the vibration transmission body 100 is seated in the seating groove 211, the tray support 110 may be placed in a state not in contact with the set plate 200.

The thickness h1 of the separation portion 130 may be the same as the vertical separation distance h2 between the tray support portion 110 and the set plate 200 . Through the spacer 130, the customer tray CT may be spaced vertically from the set plate body 210 by the second distance h2. In other words, the upper end of the tray support part 110 may be disposed higher than the upper end of the seating groove 211 . The second distance h2 may be the same as the first distance h1.

The spaced part 130 may be disposed on the lower surface of the tray support part 110 . In addition, a plurality of spacers 130 may be provided, spaced apart from each other on both sides of the protrusion 120 in the width direction (for example, in the left-right direction). The lower end of the spaced portion 130 may be disposed above the lower end of the protruding portion 120 . In other words, the thickness h1 of the spaced portion 130 may be smaller than the thickness of the protruding portion 120 .

This spaced portion 130 may extend along the front-back direction. The length of the spaced portion 130 may be greater than the width of the spaced portion 130 . For example, the width of the spacer 130 in the left-right direction may be smaller than the length of the spacer 130 in the front-back direction. The spaced portion 130 may be integrally formed with the tray support portion 110 and the protruding portion 120 . However, the spirit of the present invention is not limited thereto, and the spaced portion 130 may be formed as a separate member from the tray support portion 110 and the protruding portion 120 and connected to the lower surface of the tray support portion 110 .

Hereinafter, the operation and effect of the test handler 1 according to the third embodiment of the present invention will be described.

When the vibration transmission unit 100 of the test handler 1 is vibrated, the tray support 110 may be repeatedly moved so that the edge portion moves away from or approaches the upper surface of the set plate body 210 . Referring again to FIGS. 8 and 9, before the elevating module 12 and the vibration motor assembly 300 are operated (see FIG. 8), the plurality of electronic components D loaded on the customer tray CT Some of them may be placed in the pocket rib state (see Fig. 9).

Referring again to FIGS. 10 and 11, the vibration motor assembly 300 is driven while the elevating module 12 descends, and vibrations are generated in the vibration transmission body 100 (see FIG. 10), and these vibrations cause customer trays ( CT) and all the electronic parts (D) that were pocket ribbed on the customer tray (CT) can be normally seated on the customer tray (CT) (see FIG. 11). When the vibration transmission body 100 vibrates through the spacer 130, the test handler 1 increases the movable range of the tray support 110 by the distance between the set plate body 210 and the tray support 110. It has the effect of maximizing the size of the vibration applied to the customer tray (CT).

On the other hand, in addition to this configuration, according to the fourth embodiment of the present invention, in the vibration transmission body 100, the length of the spaced portion 130 may be smaller than the width of the protruding portion 120. Hereinafter, a third embodiment of the present invention will be described with further reference to FIGS. 13 and 14 . In the description of the third embodiment, the differences compared with the above-described embodiment are mainly described, and the same description and reference numerals refer to the above-described embodiment.

The length of the spacer 130 in the front-back direction may be smaller than the width of the protrusion 120 in the left-right direction. For example, the length of the spacer 130 in the front-back direction may be less than half of the width of the protrusion 120 in the left-right direction. The width of the spacer 130 in the left-right direction and the length in the front-back direction may be the same.

The width of the upper end of the lower part of the spaced part 130 may be greater than the width of the lower end of the lower part of the spaced part 130 . The lower portion of the spaced portion 130 may have a shape having an outwardly convex curvature. In other words, a round may be formed at a lower portion of the spaced portion 130 . The lower surface of the spacer 130 may be formed in one or more of, for example, a circular shape (see FIG. 13) and a rectangular shape (see FIG. 14).

Hereinafter, the operation and effect of the test handler 1 according to the fourth embodiment of the present invention will be described.

When the vibration transmission unit 100 of the test handler 1 is vibrated, the tray support 110 may be rotated about a left and right rotation axis passing through the spacer 130 . The left and right rotation shafts pass through the spaced portion 130 and may extend along the left and right directions. When the vibration transmission body 100 is vibrated, the tray support 110 may be rotated and vibrated around the width rotation axis. For example, when the vibration transmission body 100 is vibrated, the front and rear sides of the tray support 110 may be repeatedly moved away from or closer to the upper surface of the set plate body 210 . In other words, when the vibration transmission body 100 is vibrated, the tray support 110 may be rotated and vibrated around the left and right rotation axis in the same way as a seesaw. The test handler 1 has an effect of maximizing the amount of vibration of the customer tray CT by applying rotational vibration to the customer tray CT seated on the tray support 110 through the spaced portion 130 .
