Description

Adapter for Handlers for Electronic Component Testing

The present invention relates to an adapter that can be used in a sorter for testing electronic components.

The electronic components produced (such as semiconductor components, substrates, SSDs, etc.) are tested by a tester and divided into good products and defective products, and only good products are released from the warehouse.

Electronic components can be tested only when they are electrically connected to the tester. At this time, the equipment that supports electronic components to be tested by electrically connecting electronic components to the tester is a sorter for electronic component testing (hereinafter referred to as "sorter" ).

Sorters are proposed and produced along with the development of new electronic components, and various follow-up developments are being carried out for stabilization.

Recently, there is a tendency that the popularity of solid state drives (SSD: Solid State Drives), which are large electronic components on which a plurality of electronic components are mounted, is increasing.

Initially, when only a small amount of SSD was produced due to the low demand for SSD, the SSD was directly electrically connected to the tester and disconnected by manual operation, but as the demand for SSD increased sharply, it was difficult to support by manual operation test.

However, because the thickness, structure, and weight of SSDs are different from existing electronic components, existing sorters cannot be directly applied. Therefore, a sorter suitable for supporting the testing of large electronic components such as SSDs has been developed, and It is proposed in Korean Patent Publication No. 10-2019-0050483 and No. 10-2019-0061291.

Also, in the case of SSDs, various specifications can be obtained depending on the types of electronic components mounted or their dedicated uses, etc., and a sorter that supports testing of electronic components of such various specifications is required. However, since a sorter is expensive and has a large scale, it is estimated that there is a demand for a technology that can test electronic components having various specifications with a single sorter in consideration of production costs, installation places, and the like.

In addition, in order to test electronic components with different specifications, it is necessary to replace the components conforming to the specifications of the corresponding electronic components, and even if the components do not need to be replaced, a downtime for supplying new electronic components is required. According to this, since the operating rate of the sorting machine and the tester is reduced and complicated manpower loss occurs, it is expected that there will be a sorting machine that does not require an additional stop time even when the sorting machine is operated in one cycle or in continuous operation. demand.

In addition, in the case of semiconductor components of existing small-type mass-produced products, the following method is adopted: a test tray capable of loading more than hundreds of semiconductor components is equipped, and the semiconductor components are directly clamped and inserted by multiple holders. Insert to test tray. In such a system, since the precise position of the semiconductor element is maintained in the interposer and also in the connection procedure with the tester, there is no problem even if the accuracy is slightly lowered. However, electronic components including semiconductor elements tend to be mass-produced in small quantities in a variety of varieties to correspond to the diversity of applicable devices, and there may be cases where various tests are required. Since the test sockets of all testers do not exist in the same position, therefore , It is necessary to make expensive test trays according to the type of electronic components or the type of tester and equip them with matching sorting machines. Through previous studies, it has been found that there are considerable problems in connecting an electronic component to a test socket in a state where the electronic component is directly clamped by a clamper without considering the above-mentioned problems. For example, electronic components not only have various types, but also have various lengths and widths. Due to the characteristics of manufacturing, even electronic components of the same type are difficult to make their sizes 100% consistent due to processing errors and other reasons. However, in the case of clamping an electronic component using a clamper without considering such a situation, the electronic component may be lost due to failure to accurately clamp it, or the electronic component may be damaged due to too strong pressing force. Of course, even if the electronic component is properly clamped by adjusting the clamper, it is confirmed that the electronic component is twisted or rotated while being clamped depending on which part of the electronic component is clamped and how strong it is clamped. etc., so that it is difficult for the electronic component held by the holder to accurately contact the test socket. In order to improve this situation, the driving part needs to be able to be precisely controlled, and needs to correspond to all electronic parts, so the driving shaft also needs to be very long. In addition, in order to prevent damage, twisting, and unnecessary rotation, it is necessary to use an expensive motor capable of torque control according to circumstances. However, such a problem requires enlargement of equipment and high production cost, so it is not practical. Furthermore, it is necessary to perform automatic calibration for setting an accurate clamping position of the electronic component by the clamper to achieve precise contact, and this actually requires enormous cost and technical effort.

Therefore, the applicant of the present invention previously proposed the invention of equipping the sorting machine with an adapter in Patent Application No. 10-2020-0073725 (hereinafter referred to as "prior application technology", which is currently unpublished), in order to be able to reflect the universality sorting machine.

It functions to change the clamping width between the pair of clamping rods according to the degree of compression, so that the pair of clamping rods can clamp electronic components with various widths.

The pair of clamping rods is formed with guide grooves on the faces of the pair of clamping rods facing each other, and the guide grooves are perpendicular to the direction in which the electronic component moves linearly with the pair of clamping rods. The direction of moving and electrically connected to the tester guides the movement of the electronic component, wherein the direction perpendicular to the direction in which the pair of clamping rods move linearly is called the orthogonal direction, and the guide groove is along the The orthogonal direction is formed elongated so that the electronic component moves along the orthogonal direction along with the guide groove.

When the pair of clamping rods are in the state of clamping both ends of the electronic component, the two ends of the electronic component are inserted into the guide groove, so that the guide groove also functions as a clamping groove for The function of holding electronic components.

The electronic component test sorter to which the adapter according to the present invention is applied is more suitable for the case where the contact terminal side portion of an electronic component such as SSD is inserted into the test slot of the tester.

For example, as shown in FIG. 1 , a tester TESTER is equipped with a test slot S, and the electronic component ED is electrically connected to the tester TESTER by inserting the terminal T side of the electronic component ED into the test slot S. ＜Schematic description of the structure of the sorting machine＞

FIG. 2 is a schematic plan view of a handler HR that can use an adapter 100 (hereinafter simply referred to as “adapter”) of a handler for electronic component testing according to the present invention, and FIG. 3 is a schematic plan view of the handler HR of FIG. 2 Schematic perspective view of .

The sorter HR according to the present embodiment includes a connection part CP, a stacker part SP, and a transfer device TA.

The connection part CP takes out the electronic component ED to be tested from the customer tray CT and supplies it to the tester TESTER, or collects the tested electronic component ED from the tester TESTER and loads it on the customer tray CT. An adapter 100 according to the invention is used for the connection part CP.

The stacker section SP stores the customer trays carried into the sorter HR to supply the customer trays CT loaded with the electronic components ED to be tested to the connection section CP, or collects the customer trays loaded with the tested electronic components ED from the connection section CP. CT and keep it until it is moved out of the sorter. And, the stacker part SP supplies the customer tray CT loaded with the electronic component ED to be tested being stored to the transfer device TA, or collects the customer tray CT loaded with the tested electronic component ED from the transfer device TA.

The transfer device TA transfers the customer tray CT between the connection part CP and the stacker part SP. That is, the customer tray CT loaded with the electronic parts ED to be tested is transferred from the stacker part SP to the connection part CP by the transfer device TA, and the customer tray CT loaded with the tested electronic parts ED is transferred from the connection part CP by the transfer device TA. Part CP passes to stacker part SP. <Explanation of the schematic flow of electronic components involved in the adapter>

Since it has been described in detail in the prior art, the movement mainly of the adapter 100 is schematically described.

With the adapter 100 set on the rack, a mobile hand (not shown) takes out the electronic component ED from the customer tray CT and sets it on the adapter 100 . At this time, an opener (not shown) opens the adapter 100 so that the electronic component ED can be placed on the adapter 100 by moving the handle.

The adapter 100 mounted with the electronic part ED moves from the set position to the clamping position, and is erected by being rotated. The testing hand (not shown) moves after clamping the adapter 100 in the upright state, and electrically connects the electronic component ED to the tester TESTER. Thereafter, when the test of the electronic component ED is completed, the electronic component ED whose test has been completed is loaded on the customer tray CT through the reverse operation. ＜Instructions for the adapter＞

FIG. 4 is an exploded perspective view of the adapter 100 according to an embodiment of the present invention. 5 is a plan view of the adapter 100 of FIG. 4 , and FIG. 6 is a bottom view of the adapter 100 of FIG. 4 .

The adapter 100 includes a pair of clamping rods 111 , 112 , an installation frame 120 , a spacer 130 , elastic members 141 , 142 , 143 , 144 , 145 , 146 , a support member 150 , and restoring members 161 , 162 .

A pair of clamping bars 111, 112 can be provided to face each other, can be guided by a guide bar GB provided on the setting frame 120, and can be narrowed or widened in a direction in which the interval therebetween (in the figure Left and right directions, hereinafter referred to as "left and right directions") perform linear movement. Therefore, when the distance between the pair of clamping rods 111 and 112 is narrowed, the pair of clamping rods 111 and 112 clamp the horizontal electronic component ED. And when the space|interval between a pair of clamping rod 111,112 becomes wide, a pair of clamping rod 111,112 will be in the state which released the clamping of the electronic component ED. Therefore, if the electronic component ED is to be placed on or removed from the adapter 100 by moving the hand, the pair of clamping levers 111 and 112 should be in an open state for releasing the clamping of the electronic component ED.

Two operation grooves OG are respectively formed on the surfaces facing each other of the pair of clamp rods 111 and 112 .

The operation groove OG is formed at a portion where the clamping rods 111 , 112 contact the spacer operation device 130 . The two operation grooves OG respectively located on the same clamp lever 111 , 112 are formed side by side along a direction perpendicular to the left-right direction (the front-rear direction in the figure, hereinafter referred to as “orthogonal direction”). In addition, the operation groove OG is formed to have an inclined surface in which the depth of the depression becomes shallower toward the rear.

In addition, a guide groove GG is formed elongately along the orthogonal direction on the surfaces facing each other of the pair of clamp rods 111 and 112 and on the upper side of the operation groove OG. The guide groove GG is used in a program in which the electronic component ED moves in an orthogonal direction (for example, a program in which the electronic component to be tested is moved in order to be electrically connected to the tester or a program in which the electronic component after the test is taken out from the tester and moved to the adapter ) to guide the movement of the electronic part ED. Furthermore, when the pair of clamping rods 111 and 112 are in the state of clamping both ends of the electronic component ED, since both ends of the electronic component ED are inserted into and locked in the guide groove GG, the guide groove GG also functions as a The function of the holding groove for holding the electronic component ED.

The installation frame 120 is configured to install and support the clamping rods 111 , 112 , the spacer operating device 130 , the elastic members 141 to 146 , the supporting member 150 , and the restoration members 161 , 162 . Such an installation frame 120 has position fixing protrusions 121 protruding to the left and right on the left and right sides, respectively.

As shown in the reference diagram of FIG. 7 , the position fixing protrusion 121 is associated with the position fixing groove FG formed on the grip surface of the test hand 300 . That is, when the testing hand 300 grips the setting frame 120 and finally grips the adapter 100 , the position fixing protrusion 121 is inserted into the position fixing groove FG. Therefore, even if an external force in a direction perpendicular to the adapter 100 is applied to the adapter 100 in the state where the testing hand 300 holds the adapter 100 , the position of the installation frame 120 can be fixed and maintained, and finally the position of the adapter 100 can be fixed and maintained. Certainly, according to the embodiment, a position fixing groove may also be formed on the setting frame 120 , and a position fixing protrusion may be formed on the testing hand 300 .

In addition, two first setting holes 122 are formed at the front portion of the installation frame 120 . In addition, a first setting groove 123 is formed in the middle portion, and a second setting groove 124 is formed in the rear portion. The first setting hole 122 , the first setting groove 123 and the second setting groove 124 are formed for setting the position of the adapter 100 during the process of installing the adapter 100 on the bracket.

As shown with reference to FIG. 8 , in this embodiment, it is assumed that the position setting pin PP protruding upward is formed on the mounting surface of the bracket 200 . And, the first setting hole 122 and the setting grooves 123, 124 are formed at positions corresponding to the position setting pins PP. Therefore, in the process of installing the adapter 100 on the bracket 200, the position setting pin PP is inserted into the first setting hole 122, or is connected to the first setting hole 122 and the first setting hole 122 and the first setting hole 122 by connecting the edge surfaces of the setting grooves 123 and 124. The setting grooves 123 , 124 are matched so as to accurately set the placement position of the adapter 100 . Furthermore, the first setting hole 122 also has the function of fixing and maintaining the position of the installation frame 120 when an external force is applied to the adapter 100 in the vertical direction, and thus also has the function of fixing the position of the adapter 100 relative to the bracket 200 .

In addition, in this embodiment, it is assumed that the position setting pin PP is formed at a height that supports the electronic component ED placed on the adapter 100 in a lying state when the pair of clamping rods 111 and 112 are in the unclamped state. , thereby preventing the electronic component ED from coming off downward.

For reference, the number of the first setting hole 122 , the setting grooves 123 , 124 , and the position setting pin PP can be arbitrarily increased or decreased to an appropriate number.

In addition, in order to prevent the electronic component ED placed in a horizontal position from coming off downward when the pair of clamping rods 111 and 112 are in the unclamped state, the installation frame 120 has a first support boss 125 supporting the lower end of the electronic component ED.

The spacing operation device 130 is installed on the installation frame 120, and applies an operating force to the pair of clamping rods 111, 112 to move the pair of clamping rods 111, 112 in a direction to widen the gap between them. For this purpose, the interval operating device 130 is disposed on the installation frame 120 in a manner to be movable in an orthogonal direction, and includes an operating part 131 , a push plate 132 and a transmission rod 133 .

The operation section 131 has two scroll rollers R on the left and right sides, respectively.

The rolling roller R is provided at a position corresponding to the position of the operation groove OG. Therefore, the rolling roller R is in contact with the surface constituting the operation groove OG in a state where a part thereof is inserted into the operation groove OG. That is, both ends of the operating portion 131 of the spacer operating device 130 are in contact with the pinch rods 111 , 112 through the rolling roller R. As shown in FIG. Therefore, when the distance operation device 130 moves in the forward direction (backward in the figure), the rolling roller R contacts with the surface where the recess depth of the operation groove OG becomes shallower along with the movement, so the distance operation device 130 naturally moves toward the two sides. An operating force is applied to both the grip levers 111 and 112 in the direction in which the space between the grip levers 111 and 112 becomes wider. Here, the positive direction refers to a direction in which the adapter 100 is moved in a direction in which the operating device 130 opens the adapter 100 .

On the contrary, when the interval operating device 130 moves in the reverse direction which is the reverse direction of the forward direction, the rolling roller R contacts with the surface of the operation groove OG whose depression depth becomes deeper as the interval operating device 130 moves, and therefore, the application is naturally released. The operating force on the two clamping rods 111, 112.

The push plate 132 is subjected to an external force applied to the spacer operating device 130 in a positive direction by the opener.

The front end of the transmission rod 133 is fixedly coupled to the push plate 132 , and the rear end is fixedly coupled to the side of the operation part 131 , so that the external force of the opener input to the push plate 132 is transmitted to the operation part 131 .

In addition, a passing hole 134 and a third setting groove 135 are formed in the interval operating device 130 . The passing hole 134 and the third setting groove 135 are formed together with the first setting hole 122 , the first setting groove 123 and the second setting groove 124 to set the position of the adapter 100 when the adapter 100 is mounted on the bracket 200 .

As shown with reference to FIG. 9 , the second setting hole SH is formed by pairing the hole 134 with the second setting groove 124 . The reason for this will be described next.

The position setting pin PP of the bracket 200 has a height capable of supporting the electronic component ED mounted on the adapter 100 . For this purpose, a specific position setting pin PP must pass through the spacer 130 , and a passage hole 134 is formed in the spacer 130 . Therefore, a part of the section S1 of the edge of the second setting hole SH is provided by the second setting groove 124 formed in the setting frame 120 , and another part of the section S2 is provided by the passing hole 134 formed in the spacer 130 . Here, the specific position setting pin PP should remain inserted into the through hole 134 . Therefore, in order not to interfere with the linear movement of the spacing operation device 130 by the specific position setting pin PP, the passage hole 134 should be formed in the form of an elongated long hole along the orthogonal direction. In this way, since the form of the through hole 134 should be a long hole, a mechanical design as shown in FIG. 9 is required. Accordingly, the interference of the specific position setting pin PP with the linear movement of the pitch operation device 130 is eliminated.

The third setting groove 135 is paired with the first setting groove 123 to constrain the position setting pin PP.

The elastic members 141 to 146 are arranged such that one side thereof is in contact with the installation frame 120 and the other side thereof is in contact with the clamping rods 111 , 112 . Therefore, the elastic members 141 to 146 apply elastic force to the pair of clamp rods 111 and 112 in a direction in which the distance between the pair of clamp rods 111 and 112 becomes narrower. Accordingly, if the operating force applied to the pair of clamping rods 111, 112 is removed by the distance operating device 130, the pair of clamping rods 111, 112 will move toward each other by the elastic force of the elastic members 141 to 146. The electronic component ED is held by moving in a direction in which the space becomes narrower. From this point of view, the elastic members 141 to 146 function to generate and maintain a clamping force by which the pair of clamping rods 111 , 112 can clamp the electronic component ED, and further function to close the adapter 100 .

The elastic members 141 to 146 determine the distance between the pair of clamping rods 111 and 112 according to the degree of compression thereof. Moreover, this fact means that the elastic members 141 to 146 also function as variable elements to change the clamping width between the pair of clamping rods 111, 112 (a pair of clamping rods needs to be separated in order to clamp the electronic components). width) function. That is, according to the degree of compression of the elastic members 141 to 146 , the clamping rods 111 , 112 can clamp electronic components ED having various widths.

The supporting member 150 is provided to prevent the electronic component ED placed in a lying shape from falling out downward when the pair of clamping rods 111 and 112 are in a state where the clamping of the electronic component ED is released. Therefore, the second support boss 151 for supporting the lower end of the electronic component ED is formed on the support member 150 .

Since the support member 150 is fixed to the installation frame 120 in a U-shape, the left and right ends of the support member 150 also function as limiting members to limit the minimum distance between the pair of clamping rods 111 and 112 .

When the external force generated by the opener is removed, the restoration members 161 and 162 apply elastic force to the spacer operating device in the rearward direction in order to return the spacer operation device to the front. ＜Explanation of the role of feature composition＞

Along with replacing the original or electronic part ED to be tested, the operator places the adapter 100 matching the electronic part ED to be tested in the rack 200 . At this time, the position setting pin PP protruding upward from the installation surface of the bracket 200 is inserted into the first setting hole 122, the second setting hole SH, the first setting groove 123 and the third setting groove 135 in pairs to constrain the position setting. pin PP, so that the adapter 100 is placed on the bracket 200 in a state where its position is accurately set.

Thereafter, when the moving hand is to place the electronic component ED taken out from the customer tray CT on the adapter 100 , the opener pushes the spacer operation device 130 backward. At this time, since the position of the installation frame 120 is fixed by the position setting pin PP inserted into the first setting hole 122, only the spacer operating device 130 moves backward by the pressure of the opener. In this procedure, the restoration members 161, 162 are compressed, and the rolling roller R moves in a state of being in contact with the wall surface of the operation groove OG forming the inclined surface, and at the same time applies a force in the left and right direction to the clamping rods 111, 112, so that the two The adapter 100 is opened while the space between the clamping rods 111 and 112 is widened.

When the opening of the adapter 100 is completed, the moving hand sets the electronic part ED to the adapter 100 . At this time, the electronic component ED is placed on the first supporting boss 125 , the second supporting boss 151 and the position setting pin PP, thereby preventing it from coming off downward. Accordingly, the upper end of the position setting pin PP is preferably formed in a flat form.

If the moving hand moves to another position after unclamping the electronic component ED, the opener removes the external force applied to the spacer operating device 130 . Accordingly, the distance operating device 130 is restored forward by the restoration members 161 , 162 , and the distance between the two clamping rods 111 , 112 is reduced by the elastic force of the elastic members 141 to 146 . And, the left and right ends of the electronic component ED are inserted into the guide grooves GG of the clamping rods 111 , 112 , thereby completing the clamping of the electronic component ED by the adapter 100 .

In addition, the adapter 100 placed on the bracket 200 is clamped by the testing hand 300 , and in this procedure, the position fixing protrusion 121 is inserted into the position fixing groove FG. Accordingly, the adapter 100 is clamped on the testing hand 300 so that the adapter 100 is located at a correct setting position. And, since the position where the frame 120 is disposed can also be fixed and maintained under an external force applied to the adapter 100 later, the position of the adapter 100 can also be finally fixed and maintained.

Then, if the test hand 300 moves the adapter 100 to the TESTER side of the tester to correctly set the position between the adapter 100 and the test socket, the opening element in the test hand 300 pushes the gap operating device 130 slightly to expand the two spacers slightly. Grip the space between the rods 111, 112, in this state, the connecting element in the test hand 300 pushes the electronic part ED to the side of the test socket, so that the terminal part of the electronic part ED is inserted into the test slot S located in the test socket .

And, when the test ends, the adapter 100 is operated in a state of fixing the electronic part ED, and then, the electronic part ED is subsequently taken out from the test slot S by the test hand 300 . The electronic components ED taken out are moved through the reverse procedure, and are finally loaded on the customer tray CT. ＜References＞

In this embodiment, the position setting pin PP, the support member 150 , the first support boss 125 and the second support boss 151 are formed to support the electronic component ED placed on the adapter 100 in a lying shape. However, it is also possible to realize that the electronic component ED is clamped or released by the pair of clamp levers 111 and 112 in a state where the hands are clamped. However, in the case of realization in the latter manner, it is necessary to manage very finely the position of the moving hand, the timing of the clamping or unclamping of the moving hand, and the clamping or unclamping by the clamping levers 111, 112. point in time. And, since the processing speed decreases thereupon, therefore, more preferably, as shown in this embodiment, it is realized that the position setting pin PP, the support member 150, the first support boss 125 and the second support boss 151 are supported in a horizontal position.
