Description

Adapter of handler for testing electronic components {ADAPTOR OF HANDLER FOR TESTING ELECTRONIC COMPONENT}

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

Produced electronic components (e.g. semiconductor devices, boards, SSDs, etc.) are tested by testers and then divided into good and defective products, and only good products are shipped.

Electronic components can only be tested when they are electrically connected to a tester. At this time, the equipment that supports the testing of electronic components by electrically connecting them to the tester is an electronic component test handler (hereinafter abbreviated as 'handler'). am.

Handlers are being proposed and manufactured along with the development of new electronic components, and various future developments are being made to stabilize them.

Recently, the distribution of SSD (Solid State Drive), a large electronic component equipped with various electronic devices, is increasing.

In the beginning, when demand for SD was low and only small quantities were produced, the SD was manually connected electrically to the tester and disconnected, but as demand increased rapidly, support for manual testing became difficult.

However, since the thickness, structure, and weight of the SSD are different from those of conventional electronic components, the conventional handler could not be applied as is. Therefore, a handler suitable for testing support of large electronic components such as the SD was developed, and was published in Korean Patent No. 10-2019. It has been proposed as No. -0050483 and No. 10-2019-0061291.

In general, SD can have various standards depending on the type of electronic device mounted or its exclusive use, and a handler is required to support testing of electronic components of such various standards. However, because the handler is expensive and large in scale, a technology that can test electronic components with various specifications in one handler is required, taking into account production costs and installation locations.

In addition, in order to test electronic components with different specifications, replacement of components that meet the specifications of the electronic component is required, and even if replacement of components is not necessary, down time is required to supply new electronic components. As a result, the operation rate of handlers and testers decreases, and miscellaneous manpower is lost, so a handler that does not require a separate pause time even during one cycle operation or continuous operation of the handler is needed.

Meanwhile, in the case of semiconductor devices, which are conventional small-type mass-produced products, a test tray capable of loading hundreds of semiconductor devices is provided, and the semiconductor devices are directly grasped with a number of pickers and inserted into the insert of the test tray. . In this system, the precise position of the semiconductor device is maintained both in the insert and during the connection process with the tester, so even if the precision is somewhat low, it is not a problem.

However, electronic components such as SSD, which contain various electronic devices including semiconductor devices, are being produced in small quantities in various types in response to the diversity of applicable devices, and there are cases where various types of tests must be performed, and the test sockets of all testers are Since they do not exist in the same location, it was necessary to manufacture expensive test trays and equip appropriate handlers for each type of electronic component or tester. It has been confirmed through previous research that there are significant problems in connecting electronic components to a test socket while directly holding the electronic components with a gripper without considering this.

For example, electronic components have different lengths and widths, and due to the nature of manufacturing, it is difficult to produce 100% identical sizes even for electronic components of the same type due to processing errors. However, if you try to grip the electronic component with a gripper without considering this situation, the electronic component may not be properly gripped and may be lost or damaged due to too strong a pressing force. Of course, even if the gripper is adjusted to grip the electronic component well, depending on which part of the electronic component is gripped and the strength of the grip, situations such as twisting or rotating of the electronic component may occur while being gripped, making it difficult to grip the electronic component with the gripper. A drawback was identified in that it was difficult for an electronic component to precisely contact the test socket. In order to improve this, precise control of the driving part must be possible, and since it must correspond to all electronic components, the driving shaft must also be very long. Additionally, there is a need to use an expensive motor that can even control torque depending on the situation to prevent damage, distortion, or unnecessary rotation. However, this is not effective because it requires high production costs along with the enlargement of equipment. In addition, auto-teaching must be performed to set the exact gripping position of the electronic component by the gripper to ensure precise contact, which is a part that requires a truly enormous amount of cost and technology.

In general, in the case of SSD, the width is the same within the processing error range regardless of the type, but the length varies by type depending on the quantity or size of the mounted electronic devices.

Therefore, the applicant of the present invention has previously proposed an invention (hereinafter referred to as 'pre-filed technology') to provide an adapter to a handler to implement a versatile handler through patent application No. 10-2020-0073725. The adapter is designed to function as a carrier used to supply electronic components to the tester, and adds to the versatility of the handler by allowing it to be adapted to many types of electronic components of different sizes.

The most important points related to adapters are as follows.

First, the adapter must be able to properly grip both ends of all SDs with a width within the error range due to manufacturing tolerances.

Second, it must be able to grip all SDs within the normal length range that electronic components called SSDs can have (ranging from the shortest SD to the longest SD).

Third, a characteristic structure is needed to accurately seat the SD on the adapter. Here, the feature structure may be for the configurations surrounding the adapter, but is also required for the adapter's own configurations. If a defect occurs in the seating of the SD, this may prevent proper electrical connection between the SD and the tester in the future.

Fourth, the adapter needs to hold the SD so that the terminal area of the SD mounted on the adapter remains flat. However, during the production process, the substrate is often manufactured in a curved state, so even in the case of SDs equipped with electronic devices, they are produced in a curved state. For this reason, in the case of bent SSD, there is a need to seat it on the adapter so that the terminal area remains flat even in large quantities.

The present invention was created from concerns about technology that would enable an adapter to properly grip various electronic components regardless of manufacturing tolerance or length within the error range.

In particular, the present invention was conceived from concerns about a technology that can ensure that the terminal portion of an electronic component with a bend in an adapter is seated in an accurately flat state.

The adapter of the handler for testing electronic components according to the present invention includes a pair of grip levers that face each other and grip or release the rear end portion of the electronic component from both ends by moving linearly in the direction in which the gap between them narrows or widens; An installation frame on which the pair of grip levers are installed to enable straight movement; a gap control mechanism installed on the installation frame and applying a manipulation force to the pair of grip levers to move them in a direction that widens the gap between them; And by applying a pressing force to the pair of grip levers in a direction that narrows the gap between them, when the operating force applied to the pair of grip levers by the gap control mechanism is removed, the gap between the pair of grip levers is reduced. operating members that enable movement in this narrowing direction; The pair of grip levers includes a long guide groove in the forward and backward directions for gripping both ends of the electronic component and guiding forward and backward movement on surfaces facing each other, and a through groove through which the support protrusion of the support member on the holder can pass. This is formed.

The gap control mechanism is installed on the installation frame to enable linear movement in the forward and backward directions, both ends of the gap control mechanism are in contact with the pair of grip levers, and when moved straight backward by an external force, the pair of An operating portion provided to apply a manipulation force to the pair of grip levers in a direction in which the gap between the grip levers widens, and to release the manipulation force when the external force is removed and moves straight forward; and the pair of grip levers have rolling rollers on opposing surfaces to reduce friction with the operating portion, the rolling rollers are provided to protrude further in a direction facing each other, and the operating portion is rearward. By having inclined portions whose left and right widths gradually become narrower, the inclined portions are moved backward while in contact with the rolling rollers, thereby applying a manipulation force to the pair of grip levers.

A pressing member supported by the installation frame on one side and in contact with the space manipulation mechanism on the other side to elastically press the gap control mechanism backward; It may further include.

The installation frame has long guide rods in the left and right directions to guide the movement of the pair of grip levers, and the grip lever is formed with passing holes through which the guide rods are inserted. Among the guide rods At least one has a straight region on a cross-section cut in the front-back direction.

The installation frame has a plurality of positioning protrusions on both left and right sides that can be inserted into the positioning groove of the test hand for moving the adapter.

A receiving groove in which the rear end of the electronic component can be accommodated is formed at the rear end of the installation frame, and the left and right widths of the receiving groove are wider than the left and right widths of the rear end of the electronic component, so that the rear end of the electronic component is levitated. It can be.

The guide groove has a horizontal maintaining section that maintains the level of the gripped electronic component and a width increasing section that widens from the front end of the horizontal maintaining section toward the front.

The guide groove is located in front of the width increasing section and has an open section formed to have a width at least equal to or more expanded than the front end of the width increasing section, and the open section is divided into a rear horizontal section and a front descending section. It is further divided, and in the descending section, it extends further downward than the horizontal section.

The installation frame is provided with a plurality of positioning grooves on both left and right sides into which the positioning pins of the holder for mounting the adapter can be inserted.

The installation frame includes a pair of installation levers on which the pair of grip levers are installed at a rear portion; and a padding member for preventing the gap between the pair of installation levers from widening that may occur due to use by connecting the rear ends of the pair of installation levers; It includes, and the padding member has an exposure window through which the contact terminal of the electronic component can be exposed.

According to the present invention, the following effects are achieved.

First, even if manufacturing tolerances occur during the manufacturing process, the electronic components can be properly held and seated in the adapter.

Second, all electronic components of various lengths can be properly seated on the adapter, improving the versatility of the handler.

Third, the tight grip of the grip lever by the elastic member and the step structure of the guide groove allow the electronic components to be supported even during the posture change process, thereby creating and maintaining a flat state of the terminal area while properly maintaining the seating state of the electronic components. This improves the reliability of the handler because the electronic components can be accurately electrically connected to the tester.

<Explanation of electrical connection between electronic components and tester>

The handler to which the adapter according to the present invention is applied is more appropriately applied in cases where the contact terminal side of the electronic component, such as SSD, is inserted into the test slot of the tester.

For example, as shown in FIG. 1, the tester (TESTER) is provided with a test slot (S), and the contact terminal (T) side of the electronic component (ED) is inserted into the test slot (S), thereby making the electronic component (ED) ) and the tester are electrically connected.

<A brief description of the handler structure>

Figure 2 is a schematic plan view of a handler (HR) in which an adapter (hereinafter abbreviated as 'adapter') of a handler for testing electronic components according to the present invention can be used, and Figure 3 is a schematic plan view of the handler (HR) of Figure 2. This is a schematic three-dimensional diagram.

The handler (HR) according to this embodiment includes a connection part (CP), a stacker part (SP), and a transfer device (TA).

The connection part (CP) withdraws the electronic component (ED) to be tested from the customer tray and supplies it to the tester (TESTER), or retrieves the electronic component (ED) for which testing has been completed from the tester (TESTER) and places it on the customer tray. An adapter according to the invention is used in this connection (CP).

The stacker part (SP) stores the customer trays brought into the handler (HR) to supply the customer trays loaded with electronic components (ED) to be tested to the connection part (CP), or stores the electronic components (ED) for which testing has been completed. ) is retrieved from the connection part (CP) and stored before being taken out from the handler. In addition, the stacker part (SP) supplies customer trays containing stored electronic components (ED) to be tested to the transfer device (TA), or transfers customer trays loaded with electronic components (ED) for which testing has been completed to the transfer device. Retrieved from (TA).

The transfer device (TA) transfers the customer tray between the connection part (CP) and the stacker part (SP). In other words, the customer tray containing the electronic components (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 containing the electronic components (ED) for which testing has been completed is carried. The tray is transferred from the connection part (CP) to the stacker part (SP) by the transfer device (TA).

<A brief description of the flow of electronic components related to the adapter>

Regarding the handler (HR), since it was explained in detail in the previous application technology, the adapter-oriented flow is briefly explained.

With the adapter seated on the holder, a moving hand (not shown) withdraws the electronic component (ED) from the customer tray (CT) and places it on the adapter. At this time, an opener (not shown) opens the adapter so that the moving hand can seat the electronic component (ED) on the adapter.

The adapter on which the electronic component (ED) is seated moves from the setting position to the holding position together with the holder and is erected by rotation. The test hand (not shown) grasps the upright adapter and moves to electrically connect the electronic component (ED) to the tester. Afterwards, when the test for the electronic component (ED) is completed, the opposite operation is performed and the tested electronic component (ED) is loaded onto the customer tray (CT).

<Description of the adapter according to the first embodiment>

Figure 4 is a combined perspective view of the adapter 100 according to the first embodiment of the present invention, and Figure 5 is an exploded perspective view of the adapter 100 of Figure 4.

The adapter 100 includes a pair of grip levers 111 and 112, an installation frame 120, a gap manipulation mechanism 130, elastic members 141 to 144, and pressure members 161 and 162.

A pair of grip levers (111, 112) are provided to face each other, and are guided by guide rods (125, 126) on the installation frame (120) and can move straight in the left and right directions where the gap between them narrows or widens. there is. Therefore, when the gap between the pair of grip levers 111 and 112 is narrowed, the pair of grip levers 111 and 112 come into a state in which the rear end portion of the electronic component ED is gripped at both ends. And when the gap between the pair of grip levers 111 and 112 is widened, the pair of grip levers 111 and 112 enter an open state to release the grip of the electronic component ED. Therefore, in order for the electronic component (ED) to be seated on the adapter 100 or withdrawn from the adapter 100 by the moving hand, the pair of grip levers 111 and 112 must be in an open state to release the grip of the electronic component (ED). do.

As can be clearly seen in the excerpt of FIG. 6, each pair of grip levers 111 and 112 has two rolling rollers R arranged in the front-back direction. The rolling rollers (R) are provided to protrude more in the direction facing each other than the gripping surfaces of the pair of grip levers (111, 112).

In addition, as shown in FIG. 6, guide grooves GG are formed on the sides of the pair of grip levers 111 and 112 facing each other and extending in the front-back direction on the upper side of the rolling rollers R. This guide groove (GG) is used in the process of moving the electronic component (ED) forward and backward (for example, the process in which the electronic component to be tested moves to be electrically connected to the tester, or the electronic component that has completed testing is pulled out from the tester). It guides the movement of electronic components (ED) in the process of moving to the adapter. Furthermore, when the pair of grip levers 111 and 112 grip both ends of the rear end of the electronic component (ED), both ends of the electronic component (ED) are inserted into the guide groove (GG) and are caught in the vertical direction. Therefore, the guide groove (GG) also has the function of holding the electronic component (ED).

As shown in the virtual excerpt of FIG. 7, the guide groove (GG) sequentially passes the horizontal maintenance section (HM), width increase section (WG), penetration section (TS), and opening section (OS) in the direction from rear to front. have it as

The horizontal maintenance section (HM) is so narrow that its upper and lower width is almost the same as the upper and lower thickness of the electronic component (ED), so that it properly holds both ends of the electronic component (ED) and connects the contact terminal (at the rear end of the electronic component (ED)). It is formed so that the flatness of the area where the T) is located is maintained.

The width increase section (WG) is formed to become wider from the front end of the horizontal maintenance section (HM) toward the front. Accordingly, in the process of seating the electronic component (ED), even if sagging due to gravity or bending of the substrate itself occurs in areas other than the area adsorbed and gripped by the moving hand, the electronic component (ED) is held by both grip levers 111 and 112. Both ends of the part (ED) can be properly gripped.

The through section (TS) is formed to have a constant width in the front and rear directions at the front end of the width increasing section (WG), and the through groove (TG) through which the rear support protrusion (sp) of the support member (SE) on the stand can pass. ) corresponds to the width in the front-to-back direction. For reference, the support member (SE) is capable of being raised and lowered, so when it rises, the top of the support protrusion (sp) passes through the through groove (TG) and is in a state where it can support the electronic component (ED) in the seating process. When this happens, the support state of the electronic component (ED) is released. Of course, the supporting protrusions (sp) are formed with supporting protrusions (J) for supporting the electronic component (ED), and it is preferable that four or more are provided in a symmetrical form on the front, rear, left and right. When the support member (SE) is provided on the holder in this way, even if the adapter 100 is slightly twisted, the situation in which a defect occurs in the seating of the electronic component (ED) due to the support protrusions (sp) whose positions are fixed is prevented to that extent. do.

The open section (OS) is formed to have a width that is at least the same as or wider than the front end of the width increasing section (WG).

And the guide groove (GG) is open in the front and back directions.

As described above, the guide groove GG having the same shape as shown in FIG. 7 solves the problem of the adapter 100 holding the electronic component ED even when the electronic component ED is bent downward as shown in the exaggerated view of FIG. 8. While eliminating any scratches, the flatness of the contact terminal (T) side of the rear end is maintained, thereby contributing to the accurate insertion of the contact terminal (T) side into the test slot (S).

The installation frame 120 is provided to install and support the grip levers 111 and 112, the gap control mechanism 130, the elastic members 141 to 146, and the pressure members 161 and 162.

The installation frame 120 has two positioning protrusions 121 protruding to the left and right, respectively, on both left and right sides of its front end.

The positioning protrusions 121 are related to the positioning groove (SG) formed on the gripping surface of the test hand 400, as shown in the reference diagram of FIG. 9. That is, when the test hand 400 ultimately grasps the adapter 100 by grasping the installation frame 120, the positioning protrusion 121 is inserted into the positioning groove (SG). Therefore, in a state in which the test hand 400 holds the adapter 100, the position of the installation frame 120 is fixed and maintained even if an external force is applied to the adapter 100 in the front and rear directions, ultimately changing the position of the adapter 100. can be fixed and maintained. Of course, depending on the implementation, a positioning groove may be formed in the installation frame 120 and a positioning protrusion may be formed in the test hand 400.

As in the present embodiment, if a plurality of positioning protrusions 221 are provided on both left and right sides at regular intervals in the front and rear directions, the front end portion of the adapter 200 held by the test hand 400 is moved by gravity. By descending while rotating, poor grip on the electronic component (ED) is prevented. Here, referring to FIG. 10, it can be seen that one of the two positioning protrusions 121 is cylindrical with a relatively short protrusion, and the other has a relatively long protrusion and is roughly conical. According to this example, in the process of the test hand 400 gripping the adapter 200, the conical positioning protrusion 121 can contribute to correcting the position and posture of the adapter 100, and the cylindrical positioning protrusion 121 ) can contribute to accurately maintaining the set position, thereby eliminating defects resulting from manufacturing tolerances of the positioning protrusions 121.

In addition, the installation frame 120 has long guide rods 125 and 126 in the left and right directions to guide the straight left and right movement of the pair of grip levers 111 and 112. Of course, the grip levers 111 and 112 are formed with passing holes TH through which the guide rods 125 and 126 are inserted.

Additionally, a receiving groove (AG) is formed at the front end of the installation frame 120 to accommodate the front end of the electronic component (ED). Here, the left and right widths of the receiving groove (AG) are wider than the left and right widths of the front end of the electronic component (ED), so that both sides of the front end of the electronic component (ED) are mechanically pressed or caught by the adapter 100. It is not gripped and remains in a suspended form. This receiving groove (AG), like the guiding groove (GG), is also open in the front-back direction. This means that the seating space of the adapter 100 where the electronic component (ED) is seated is open in the front and rear directions. That is, the seating space including the guide groove (GG) and the receiving groove (AG) is open in the front and rear directions. Therefore, electronic components (ED) of various lengths can be seated across the guide groove (GG) and receiving groove (AG) without restrictions on their length.

In addition, the installation frame 120 has two position fixing grooves (FG) on the left and right sides into which the position fixing pins of the holder can be inserted at the rear end. Two or more of these position fixing grooves (FG) may be formed on both left and right sides. And the position fixing grooves (FG) and position fixing pins serve to correct and fix the position of the adapter 100 held in the holder. Therefore, when the holder moves or rotates, the adapter 100 is prevented from being separated. In addition, the position fixing groove (FG) and the position fixing pins function to maintain the installation frame 120 in its position even if an external force is applied in the front and rear directions to the adapter 100 coupled to the holder.

In addition, the installation frame 230 further has a separate padding member 128 in addition to a pair of installation levers 123 and 124 on which a pair of grip levers 111 and 112 are installed at the rear portion.

The padding member 128 connects the rear ends of a pair of installation levers 123 and 124, which may be caused by use due to the pressing force of the elastic members 141 to 144 continuously applied. Prevent the gap between them from widening. This padding member 128 has an exposure window (W) through which the contact terminal (T) of the electronic component (ED) can be exposed.

The gap control mechanism 130 is installed on the installation frame 120 and applies a manipulation force to the pair of grip levers 111 and 112 to move them in the direction of widening the gap between them. For this purpose, the gap control mechanism 130 is installed on the installation frame 120 so that it can move in the front and rear directions, and includes an operation part 131, a pushing plate 132, and a transmission rod 133.

The manipulation part 131 has two inclined parts (TP) in the front-back direction on both left and right sides whose left and right widths become narrower toward the rear. Therefore, the inclined portions (TP) are moved rearward while in contact with the rolling rollers (R) of the grip levers (111, 112), and the operating part 131 is spaced between the pair of grip levers (111, 112). Manipulating force is applied in the direction of expansion. Conversely, when the gap control mechanism 130 moves forward, the operating force applied to both grip levers 111 and 112 is naturally released as it moves forward.

The push plate 132 receives an external force applied in the positive direction to the gap manipulation mechanism 130 by an opener (not shown). That is, the opener applies a force backward through the push plate 132 to supply a driving force that allows the gap control mechanism 130 to move rearward, and the gap control mechanism 130 moves rearward by the driving force of the opener. I do it.

The front end of the transmission rod 133 is fixedly coupled to the pushing plate 132, and the rear end is fixedly coupled to the operating part 131, thereby transmitting the external force of the opener that pushes the pushing plate 132 backward to the operating part 131. do.

The elastic members 141 to 144 are installed so that one side is in contact with the installation frame 120 and the other side is in contact with the grip levers 111 and 112. Accordingly, the elastic members 141 to 144 apply elastic force to the pair of grip levers 111 and 112 in a direction in which the gap between the pair of grip levers 111 and 112 narrows. Accordingly, when the operating force applied to the pair of grip levers 111 and 112 by the gap manipulation mechanism 130 is removed, the pair of grip levers 111 and 112 are moved by the elastic force of the elastic members 141 to 144. The electronic component (ED) is gripped as it moves in a direction where the gap between them narrows. From this perspective, the elastic members 141 to 144 function as operating members that generate and maintain a pressing force that allows the pair of grip levers 111 and 112 to grip the electronic component (ED), and furthermore, It functions to close the adapter 100. Of course, motors, cylinders, etc. can be considered as operating members, but in order to respond to all widths of electronic components (ED) within the processing error range without separate settings, it is most desirable to construct the operating members with elastic members such as springs. You can.

The distance between the pair of grip levers 111 and 112 of the elastic members 141 to 144 is determined according to the degree of compression. And this fact shows that the elastic members 141 to 144 are also variable elements that change the gripping width between the pair of gripping levers 111 and 112 (the width that the pair of gripping levers must be spaced apart from to grip the electronic component). It means functioning. That is, depending on the degree of compression of the elastic members 141 to 144, the grip levers 111 and 112 can grip electronic components ED having various widths within manufacturing tolerances.

When the external force caused by the opener is removed, the pressing members 161 and 162 apply elastic force to the gap control mechanism 130 forward in order to smoothly restore the gap control mechanism 130 to its forward position. Since these pressing members (161, 162) press the gap control mechanism (130) forward, the gripping force of the elastic members (141 to 144) that apply elastic force to the pair of gripping levers (111, 112) in a direction that narrows each other It also contributes to strengthening.

Next, the operation of the adapter 100 as described above will be described.

As the electronic component (ED) to be initially or tested is replaced, the operator places the adapter 100 that meets the standards of the electronic component (ED) to be tested into the holder. Afterwards, when the moving hand wants to seat the electronic component (ED) drawn from the customer tray into the adapter 100, the opener pushes the gap control mechanism 130 backward. At this time, since the installation frame 120 is fixed to the holder by the position fixing groove (FG), only the gap control mechanism 130 moves rearward due to the pressing force of the opener. In this process, the inclined parts (TP) of the manipulation part 131 move backward while in contact with the rolling rollers (R) of the grip levers 111 and 112, and exert force in the left and right directions on the grip levers 111 and 112. By applying, the gap between the two grip levers 111 and 112 widens and the adapter 100 is opened. Then, the support member (SE) of the cradle rises so that the support protrusion (sp) can support the electronic component (ED). Therefore, the rear end of the electronic component (ED) can be supported by being placed on the support jaws (J) at four locations of the support member (SE).

When the opening of the adapter 100 is completed, the mobile hand that has suction-gripped the upper surface of the electronic component (ED) is lowered to a height where the rear end of the electronic component (ED) is placed on the support jaws (J). This lowering process is also the process by which the bent rear end of the electronic component (ED) is converted to a flat state. In other words, the lowering of the electronic component (ED) by the moving hand is achieved to a position where the electronic component (ED) is spread flat so that both left and right ends of the rear end are properly inserted into the guide grooves (GG) of the holding members (111, 112). will be. Therefore, even if the electronic component (ED) is bent to a certain degree, the electronic component (ED) can be properly held by the grip levers 111 and 112 through the guide groove (GG). Here, since the rear end of the electronic component (ED) is supported by the supports (J) at a total of four locations on both the front, left, and right sides, the rear end of the electronic component (ED) is flat due to the downward pressure applied by the moving hand. It is spread out, and for this purpose, the point that is adsorbed and held by the moving hand needs to be located between four support points (preferably at the point where two diagonal lines connecting two support points diagonally intersect). Therefore, it is desirable to have at least four support protrusions (sp) on the support member (SE).

Next, the external force applied to the gap manipulation mechanism 130 is removed while the rear end portion of the electronic component ED is supported by the support jaw J. Then, the gap between the two grip levers 111 and 112 is narrowed by the elastic force of the elastic members 141 to 144, and the gap control mechanism 130 is also pushed forward. In this process, both left and right ends of the electronic component (ED) are inserted into the guide grooves (GG) of the grip levers (111, 112), thereby completing the gripping of the electronic component (ED) by the adapter (100). At this time, due to the shape of the guide groove GG, the rear portion of the electronic component ED (more specifically, the portion where the contact terminal is located) can be maintained flat. In addition, even if there is a wider tolerance in the left and right widths of the electronic component (ED), because the width of the receiving groove (AG) is sufficiently wide, a situation occurs where the rear end of the electronic component (ED) gets caught in the wall forming the receiving groove (AG). It doesn't work.

When the gripping of the electronic component (ED) by the grip levers 111 and 112 is completed, the moving hand releases the gripping of the electronic component (ED) and then moves to another location.

Meanwhile, the adapter 100, which was seated on the cradle, is erected vertically. At this time, the lower end of the vertically standing electronic component (ED) is supported by the wall forming the guide groove (GG) and the support jaw (J), and further, the pressing force of both grip levers (111, 112) and, depending on the case, Due to the bending restoring force that may occur, the seated state is properly maintained by being stuck in the guide groove GG. In this way, the adapter 100, which was in a vertical state and seated on the cradle, is gripped by the test hand 400, and in this process, the positioning protrusion 121 is inserted into the positioning groove (SG). Accordingly, the adapter 100 is held by the test hand 400 so that it is positioned at the correct setting position. Moreover, since the position of the installation frame 120 can be fixed and maintained even in the event of external force applied to the adapter 100 in the future, the position of the adapter 100 can ultimately be fixed and maintained.

When the test hand 400 moves the adapter 100 toward the tester (TESTER) and the position between the adapter 100 and the test slot (S) is accurately set, the opening element in the test hand 400 is used as a gap control mechanism. (130) is slightly pushed to slightly widen the gap between the two grip levers (111, 112), and in that state, the connection element in the test hand (400) pushes the electronic component (ED) toward the test slot (S) to Insert the rear end of (ED) with the contact terminal (T) into the test slot (S).

And when the test is completed, the adapter 100 is operated to fix the electronic component (ED), and then the electronic component (ED) is pulled out from the test slot (S) by the test hand 400. The withdrawn electronic components (ED) go through the reverse process and are ultimately placed on the customer tray (CT).

<Description of the adapter according to the second embodiment>

Figure 11 is a combined perspective view of the adapter 200 according to the second embodiment of the present invention, and Figure 12 is an exploded perspective view of the adapter 200 of Figure 11.

The adapter 200 includes a pair of grip levers 211 and 212, an installation frame 220, a gap manipulation mechanism 230, elastic members 241 to 244, and pressure members 261 and 262.

A pair of grip levers (211, 212) are provided to face each other, and are guided by guide rods (225, 226) on the installation frame (220) while moving straight in the left and right directions where the gap between them narrows or widens. It is in an open state that grips the electronic component (ED) or releases the grip of the electronic component (ED).

As shown in the excerpt of FIG. 13, two operating grooves OG are formed on opposing surfaces of the pair of grip levers 211 and 212, respectively.

The operating groove (OG) is formed at the area where the grip levers 211 and 212 and the gap manipulation mechanism 230 contact. The two operating grooves OG on the same grip levers 211 and 212 are formed side by side in the front-back direction. And the operating groove (OG) is formed to have an inclined surface where the depth of the depression becomes shallower toward the rear.

As in the first embodiment, the pair of grip levers 211 and 212 has guiding grooves GG formed on the surfaces facing each other and extending in the front-back direction above the operating grooves OG. Likewise, the guide groove (GG) has a horizontal maintenance section (HM), a width increase section (WG), a penetration section (TS), and an opening section (OS) in the direction from rear to front, as shown in the virtual excerpt of Figure 14. have them sequentially. However, the open section (OS) in the second embodiment can be further divided into a rear horizontal section (OS1) and a front lowering section (OS2), and in the lowering section (OS2), the width is further expanded downward. As a result, even electronic components (ED) with larger bends can be properly accommodated.

The installation frame 220 is provided to install and support the grip levers 211 and 212, the gap control mechanism 230, the elastic members 241 to 246, and the pressure members 261 and 262. The installation frame 220 in the second embodiment also includes a positioning protrusion 221, an installation lever 223, 224, a guide rod 225, 226, an accommodation groove (AG), a position fixing groove (FG), and an exposure window. It has a padding member (128) with (W).

However, at least one of the guide rods 225 and 226 in the second embodiment (in this embodiment, the guide rod indicated by symbol 226) has both left and right end regions left and right on a cross-section cut in the anteroposterior direction, as shown in the excerpted front view of FIG. 15. When viewed from the direction, the upper side is formed to have a straight line. And the guide rod of symbol 226 is coupled to the installation levers 223 and 224 in a straight area, so its rotation is prevented by its straight shape.

In addition, the guide rod of symbol 226 is formed so that the upper and lower sides are cut flat in the middle region so that both the upper and lower sides have a straight shape in a cross-section cut in the front-back direction. In this way, the upper side of the guide rod 226 does not interfere with the electronic component (ED), and the lower side does not interfere with the gap control mechanism 230, and the cross-sectional area can be secured to be wide. As a result, the rigidity of the guide rod 226 is improved and the guide rod 226 can be prevented from being bent or deformed during use.

Of course, in order to prevent rotation and maintain rigidity, it can be fully considered that the guide rod 226 has a square cross-section over the entire area as shown in FIG. 16.

The gap control mechanism 230 is installed on the installation frame 220, and applies a manipulation force to the pair of grip levers 211 and 212 to move them in the direction of widening the gap between them. The gap control mechanism 230 in the second embodiment also includes an operation part 231, a pushing plate 232, and a transmission rod 233.

The operating part 230 in the second embodiment has two rolling rollers (R) on both left and right sides corresponding to the operating groove (OG), and the rolling rollers (R) protrude outward from both left and right sides. form a region. And the rolling rollers (R) are in contact with the surface forming the operating groove (OG) with some of them inserted into the operating groove (OG). That is, both ends of the manipulation part 131 of the gap manipulation mechanism 130 are in contact with the grip levers 211 and 212 through the rolling rollers R. Therefore, when the gap control mechanism 230 moves rearward, the rolling rollers (R) come into contact with the inclined surface where the depth of the depression in the control groove (OG) becomes shallower as it moves, so naturally the gap control mechanism 230 moves both grip levers ( Manipulating force is applied to both grip levers (211, 212) in a direction that widens the gap between them (211, 212). Of course, when the gap control mechanism 230 moves forward, the rolling rollers (R) come into contact with the inclined surface where the depth of the depression in the control groove (OG) becomes deeper as it moves, so it is naturally applied to both grip levers 211 and 212. The operating power that was lost is being released.

The elastic members 241 to 244 and the pressing members 261 and 262 are the same as in the first embodiment.

Since the operation of the adapter 200 according to the above second embodiment is substantially the same as that of the adapter 100 according to the first embodiment, its description is omitted.

As described above, the specific description of the present invention has been made by way of examples with reference to the accompanying drawings. However, since the above-described embodiments are only explained by referring to preferred examples of the present invention, the present invention is limited to the above-described embodiments. It should not be understood as limited, and the scope of rights of the present invention should be understood as the scope of the claims described later and their equivalents.
