Description

Technical Field

[0001] The present invention relates to a holder for placing electronic components in an electronic component sorting machine. Background Technology

[0002] Electronic components undergo multiple manufacturing processes and are shipped after testing. At this point, electronic component sorting machines (hereinafter referred to as "sorting machines") are used in several processing steps to separate the electronic components. In particular, sorting machines are essential for testing and classifying the electronic components produced.

[0003] With the development of new electronic components or the required processes, sorting machines are being proposed and manufactured with new structures, and various follow-up developments are underway for stabilization.

[0004] Recently, the trend of solid-state drives (SSDs), which are large electronic components containing multiple electronic parts, is expanding.

[0005] Initially, due to low demand for solid-state drives (SSDs), they were handled manually when only small quantities were produced. This was especially true during the testing process, where SSDs were manually connected to and disconnected from the test equipment. However, with the surge in demand, manual testing support became increasingly difficult.

[0006] However, because solid-state drives (SSDs) differ from existing electronic components in thickness, structure, and weight, existing sorting machines cannot be directly applied. Therefore, the applicant of this invention previously proposed a sorting machine suitable for testing support of large electronic components such as SSDs in Korean Patent Publications Nos. 10-2019-0050483 and 10-2019-0061291.

[0007] Furthermore, existing sorting machines are designed to process only electronic components of the same specifications, or require the replacement of multiple components when the specifications of the electronic components to be processed change. This necessitates a sorting machine that corresponds to the number of electronic components of various specifications being processed, resulting in wasted construction costs and space, or reduced uptime due to component replacements.

[0008] Furthermore, since electronic components such as solid-state drives vary greatly in specifications depending on the finished product they are used in, they are actually produced using a system that produces a wide variety of products in small quantities. In view of this situation, the applicant of this invention proposed a universal sorting machine in Korean Patent Application No. 10-20-0073725 (hereinafter referred to as the "prior application invention").

[0009] According to the sorting machine of the prior art, an adapter is used, which functions as a carrier for supplying electronic components to the tester. Thus, by simply changing the adapter, a single sorting machine can process various types of electronic components of different sizes.

[0010] The adapter has a pair of gripping rails for holding and releasing the mounted electronic components. During the placement or removal of the electronic components from the adapter, the spacing between the gripping rails widens, necessitating that the adapter be in an open state. Furthermore, when the adapter is in the open state, a separate support protrusion is required to maintain the position of the electronic components.

[0011] Furthermore, although electronic components are manufactured with great precision, tolerances are inevitable. For example, when manufacturing an electronic component with a width of 22mm, the actual width of the manufactured component reflects a tolerance of 0.15mm, resulting in a range from 21.85mm to 22.15mm. Therefore, the width supported by the support device can only be set to 22.15mm.

[0012] However, as Figure 20 As shown in the reference figure, the support platform sj formed on the support protrusions 213a and 213b is formed to only support about 0.25mm on the left and right ends of the electronic component ED due to interference with the structure of the electronic component ED or other structures of the adapter. Therefore, as Figure 21 As shown, the electronic component ED, with a width of 21.85mm reflecting negative tolerance, cannot be properly supported by the support table sj and may experience improper placement, potentially causing it to sag downwards on one side. Furthermore, if improper placement occurs, it needs to be rectified after stopping the sorting machine's operation, thus potentially leading to a decrease in the sorting machine's operating rate or damage to the electronic component ED. Summary of the Invention

[0013] This invention is proposed based on the concept of a structure that can well support electronic components manufactured with different widths due to tolerances.

[0014] The electronic component sorting machine holder according to the present invention includes: a pair of gripping rods capable of gripping or releasing an adapter on which electronic components are detachably placed; a drive source capable of gripping or releasing the adapter by narrowing or widening the gap between the pair of gripping rods; a pair of movable guides supporting the electronic components in a state where the adapter is open by an opening machine, and guiding the placement position of the electronic components during placement into the adapter; and a restoring member that, after applying an external force to the pair of movable guides to move them, if the external force is removed from the pair of movable guides, restores the position of the pair of movable guides. The guide is restored to its original position; and a frame is provided for accommodating the pair of grip rods, the drive source, the pair of movable guides, and the restoration component, wherein the movable guides are movably disposed in the frame and protrude upward through the passage area of ​​the adapter to support electronic components mounted on the adapter. The pair of movable guides includes: a guide portion, the width of which narrows as the facing surfaces downwards, thereby guiding the placement position of the electronic components; and a support portion located below the guide portion to support the electronic components, thereby forming a support platform for positioning the electronic components in the adapter.

[0015] The pair of movable guides are hinged to the mounting frame at their lower ends so that the spacing between the support platforms of the pair of guides can be widened or narrowed by rotational movement.

[0016] The restoring component has a pair of restoring springs that restore the pair of movable guides respectively.

[0017] The recovery component has a pair of recovery springs for restoring the pair of movable guides together.

[0018] It also includes: a pair of fixed guides, fixedly disposed on the mounting frame, which can support the electronic components when the adapter is opened by the opening mechanism, and guide the placement position of the electronic components during the process of placing the electronic components into the adapter.

[0019] It also includes: an anti-protrusion device, fixedly mounted on the mounting frame, for preventing the electronic components placed on the adapter from tilting when the adapter is open by the unclamping mechanism.

[0020] It also includes: sensors for detecting improper placement of electronic components during the process of placing electronic components into the adapter.

[0021] According to the present invention, electronic components manufactured with different widths due to tolerances can be stably mounted on the adapter, thus ultimately improving the operating rate of the sorting machine. Attached Figure Description

[0050] <Instructions for Electrical Connections Between Electronic Components and Testers>

[0051] The sorting machine employing the holder for electronic component sorting machine according to the present invention (hereinafter referred to as "holder") is more suitable for inserting the contact terminal side of electronic components such as solid-state drives into the test slit of the tester.

[0052] For example, such as Figure 1 As shown, the tester (TESTER) has a test slit S, and the terminal T side portion of the electronic component (ED) is inserted into the test slit S, thereby creating a structure in which the electronic component (ED) and the tester (TESTER) are electrically connected. Here, as... Figure 1 As shown, the test slit S can be either longer in the vertical direction or longer in the horizontal direction.

[0053] <Illustrative explanation of the main components of a sorting machine>

[0054] Figure 2 This is a schematic floor plan of the sorting machine HR. Figure 3 yes Figure 2 A schematic 3D diagram of the HR sorting machine.

[0055] The sorting machine HR according to this embodiment includes a connecting part CP, a stacking part SP, and a conveying device TA.

[0056] The connection section CP removes the electronic component ED to be tested from the user tray CT and provides it to the tester TESTER, or retrieves the electronic component ED after testing from the tester TESTER and loads it back into the user tray CT. A holder according to the invention is provided in this connection section CP.

[0057] The stacking section SP stores and moves user trays loaded with electronic components ED to be tested (ED) into the sorting machine HR before supplying them to the connecting section CP, or retrieves user trays loaded with tested electronic components ED from the connecting section CP and moves them out of the sorting machine HR. Furthermore, the stacking section SP provides the stored user trays CT loaded with tested electronic components ED to the conveying device TA, or retrieves user trays CT loaded with tested electronic components ED from the conveying device TA.

[0058] The conveyor TA transfers the user tray CT between the connecting section CP and the stacking section SP. That is, the user tray CT, loaded with the electronic component ED to be tested, is transferred from the stacking section SP to the connecting section CP via the conveyor TA, and the user tray CT, loaded with the electronic component ED after testing, is transferred from the connecting section CP to the stacking section SP via the conveyor TA.

[0059] Electronic components ED, which need to be tested in the sorting machine HR as described above, are moved from the stacking section SP to the connecting section CP via the conveying device TA while loaded on the user tray CT. In the connecting section CP, they are moved from the user tray CT to the relay device 100 via the moving handle MH, and supplied from the relay device 100 to the tester TESTER via the test handle TH. Afterwards, the tested electronic components ED are moved to the stacking section SP via the reverse process described above.

[0060] Here, the mobile handle MH has a structure that holds the electronic component ED by vacuum adsorption, and the test handle TH has a structure that holds the electronic component ED by applying pressure at both ends.

[0061] <Adapter manage A summary of the process flow for the electronic components implemented in the connection section >

[0062] As detailed in the prior art application, see reference Figure 4 The conceptual diagram outlines the process of electronic components (ED) performed when using the adapter (AD).

[0063] With the adapter AD placed on the relay device 100, the mobile handle MH removes the electronic component ED from the user tray CT and places it on the adapter AD located in the first work area WA1. At this time, the relay device 100 opens the adapter AD, allowing the mobile handle MH to place the electronic component ED on the adapter AD.

[0064] When the first operation of placing the electronic component ED onto the adapter AD is completed, the relay device 100 moves the adapter AD from the first operation area WA1 to the second operation area WA2. Here, the first operation area WA1 is behind the second operation area WA2.

[0065] When the adapter AD completes its movement to the second working area WA2, the relay device 100 rotates the adapter AD, changing the orientation of the electronic component ED mounted on the adapter AD from horizontal to vertical. Then, the test handle TH grasps the adapter AD and moves it, thereby electrically connecting the electronic component ED mounted on the adapter AD to the tester TESTER. Then, if the testing of the electronic component ED is completed, the reverse operation is performed, and the tested electronic component ED moves to the user tray CT.

[0066] <Illustrative description of the adapter>

[0067] Figure 5 As shown in the applicant's prior Korean Patent Application No. 10-2021-0017446 (hereinafter referred to as the "prior application"), the opening lever FL can be pressurized or depressurized by an opening device (described later). When the opening lever FL is pressurized, the gap between the pair of gripping rails GR1 and GR2 widens, thereby opening the adapter AD, allowing the electronic component ED to be placed in or removed from the adapter AD. Furthermore, when the pressure on the opening lever FL is depressurized, the gap between the pair of operating rails GR1 and GR2 narrows, thereby closing the adapter AD, in which case the electronic component ED placed in the adapter AD is fixed.

[0068] Other structures or operating structures of the adapter AD as described above have been described in detail in the prior applications mentioned above, and therefore are omitted in this specification.

[0069] Since this adapter AD is detachably attached to the relay device 100, it can be moved together with the electronic components ED via the test handle TH.

[0070] For reference, the adapter has a passage area pf that allows the flow-type guide and the fixed-type guide, which will be described later, to pass through.

[0071] <Illustrative explanation of the purpose and structure of the relay device>

[0072] The relay device 100 relays electronic components ED between the moving handle MH and the test handle TH. The moving handle MH and the test handle TH are responsible for supplying electronic components ED located in the user tray CT to the tester TESTER or for recovering electronic components ED that have completed testing from the tester TESTER back to the user tray CT.

[0073] Typically, large electronic components (EDs) with wide shapes, such as solid-state drives (SSDs), are supplied to the sorting machine (HR) in a horizontally mounted state on the user tray (CT). Therefore, holding the EDs using a vacuum suction method is suitable for retrieving them from the CT. However, holding the EDs using a vacuum suction method is not suitable for forcibly inserting them into the test slit (S) of the tester (TESTER). Instead, holding them by applying pressure to both ends is appropriate. This is because by applying pressure to both ends, it is easy to create a structure that properly guides the movement of the EDs for insertion.

[0074] Therefore, as shown in the aforementioned related applications, the sorting machine HR needs to have two gripping structures for holding the electronic component ED. One is a moving handle MH that can hold the electronic component ED by vacuum adsorption, and the other is a test handle TH that can hold the electronic component ED by applying pressure at both ends.

[0075] The moving handle MH is used to retrieve electronic components ED from or load electronic components ED onto the user tray CT. The test handle TH is used when inserting or retrieving electronic components ED into or from the test slit S of the tester TESTER.

[0076] Furthermore, if the working area of ​​the moving handle MH overlaps with the working area of ​​the test handle TH, not only will the control design to prevent interference between them become very complex, but the operating rate will also decrease. Therefore, as mentioned above, it is best to separate the working areas WA1 and WA2. Additionally, when the test slit S is elongated vertically, it is necessary to convert the horizontal electronic component ED to a vertical position. Therefore, a relay device 100 as described in this invention is required.

[0077] That is, the relay device 100 according to the present invention is provided for the following reasons.

[0078] First, an appropriate relay electronic component ED is needed between the movable handle MH, which has a vacuum adsorption structure, and the test handle TH, which has a two-end pressurization structure.

[0079] Second, during the relay process, it is necessary to change the orientation of the electronic component ED from horizontal to vertical or vice versa.

[0080] Third, it is necessary to prevent the working areas WA1 and WA2 of the moving handle MH and the test handle TH from overlapping.

[0081] Fourth, the sorting machine HR needs to process electronic components ED of various specifications.

[0082] Therefore, as in Figure 6 Conceptual diagram and omission of the round-trip mobile device 120 Figure 7 As shown in the partial excerpt of the figure, the relay device 100 includes a holder 110, a reciprocating mover 120, a posture converter 130, and an opener 140.

[0083] The holder 110 is provided for holding the previously described adapter AD. Furthermore, the present invention relates to such a holder 110, which will be described in more detail in another section below.

[0084] The reciprocating mover 120 causes the holder 110 to move back and forth between a first working area WA1 where the moving handle MH performs operations and a second working area WA2 where the test handle TH performs operations. Therefore, the first working area WA1 and the second working area WA2 can be separated from each other without overlapping, and operational interference between the moving handle MH and the test handle TH can be prevented.

[0085] The posture converter 130 rotates the adapter AD placed on the holder 110 by rotating the holder 110, thereby ultimately rotating the electronic component ED placed on the adapter AD, thus changing the posture of the electronic component ED. For reference, the posture of the electronic component ED changes from horizontal to vertical during the process of supplying the electronic component ED to the tester TESTER, and the posture of the electronic component ED changes from vertical to horizontal during the process of returning the electronic component ED to the user tray CT.

[0086] The opener 140 opens the adapter AD, allowing the electronic component ED to be placed in the adapter AD or to be extracted from the adapter AD. For example... Figure 8 As shown in the excerpt, this opener 140 includes a pressure rod 141, a pressure source 142, and a return spring 143.

[0087] The pressure rod 141 applies pressure to the opening rod FL of the adapter AD to open the adapter AD.

[0088] The pressure source 142 pressurizes or depressurizes the release lever FL of the adapter AD by moving the pressure lever 141 forward and backward. Although a cylinder is used as such a pressure source 142 in this embodiment, it is not necessarily limited to a cylinder.

[0089] The rebound spring 143 is configured as an elastic member that applies a spring force to the pressure rod 141 in the direction of releasing pressure when no pressure is supplied from the pressure source 142.

[0090] Additionally, it should be noted that the shelf 110 rotates via the posture converter 130. Therefore, in order to open the adapter AD placed on the shelf 110, it would be preferable to attach the opener 140 to the shelf 110. However, due to the operating structure of the shelf 110 itself, it is difficult to attach the opener 140 to the shelf 110. Therefore, in this embodiment, by employing a structure in which the pressure rod 141 is rotatably attached to the pressure source 142, the pressure rod 141 can rotate together with the shelf 110 when it rotates via the posture converter 130.

[0091] For reference, since the posture converter 130 and the opener 140 need to move back and forth together with the holder 110, they are respectively coupled to the holder 110 in an operable structure and move together with the holder 110.

[0092] <Instructions for the shelf>

[0093] like Figure 9 , Figure 10 and Figure 11 As shown in the excerpt, the holder 110 has a pair of grip rods 111a, 111b, a drive source 112, a pair of movable guides 113a, 113b, a pair of fixed guides 114a, 114b, a pair of restoring springs 115a, 115b, a mounting frame 116, and a sensor 117.

[0094] For a pair of grip levers 111a and 111b and drive source 112, refer to Figure 12 and Figure 13 The following is an excerpt from the image for explanation.

[0095] A pair of gripping levers 111a and 111b grip or release the adapter AD by narrowing or widening the gap between them.

[0096] The drive source 112 provides a driving force that enables the pair of gripping rods 111a and 111b to automatically grip or release the adapter AD by reducing or increasing the gap between them. In this embodiment, instead of directly supplying the driving force from the drive source to the pair of gripping rods 111a and 111b, the driving force is transmitted through a guide rail a, a pair of rotating links b, and a forward / backward component c.

[0097] When the grip levers 111a and 111b move to the left or right, the guide rail a guides the movement of the grip levers 111a and 111b. For this purpose, the grip levers 111a and 111b are mounted on the guide rail a.

[0098] One side of a pair of rotating links b is rotatably connected to gripping rods 111a and 111b, and the other side is rotatably connected to the forward / backward component c. Therefore, while the rotating links b rotate by the forward or backward movement of the forward / backward component c, the gripping rods 111a and 111b are pushed or pulled in the left and right directions.

[0099] The forward and backward component c moves forward and rotates by the driving force of the drive source 112.

[0100] For reference, in this embodiment, the driving force of the drive source 112, which is composed of a cylinder, is transmitted to a pair of gripping rods 111a and 111b through the forward and backward component c, etc. However, any structure can be preferred as long as the interval between the pair of gripping rods 111a and 111b can be changed.

[0101] Furthermore, the pair of grip rods 111a and 111b should be able to grip or release the adapter AD when the electronic component ED is in a horizontal position, and should also be able to grip or release the adapter AD when the electronic component ED is in an upright position. Therefore, the grip rods 111a and 111b and the drive source 112 should be configured to rotate together with the mounting frame 116 via the posture converter 130. For this purpose, in this embodiment, a structure is adopted in which the grip rods 111a and 111b and the drive source 112 are operably integrated into the mounting frame 116. As in... Figure 11 As can be seen from the diagram, the drive source 117 is located on the opposite side of the mounting adapter AD, that is, on the back of the mounting frame 116, so that while properly supplying drive force to the pair of grip rods 111a, 111b, it does not interfere with the mounting of the adapter AD.

[0102] A pair of movable guides 113a and 113b can support the electronic component ED in an open state via the opener 140 to maintain the position of the electronic component ED, and guide the placement position of the electronic component ED during placement onto the adapter AD. These movable guides 113a and 113b are hinged to the bracket B fixed to the mounting frame 116, thus ultimately being rotatably and movablely mounted on the mounting frame 116. Furthermore, they can protrude upwards through the passage area pf of the adapter AD, thereby supporting the electronic component ED placed on the adapter AD. For this purpose, as... Figure 14 As shown in the excerpt, the movable guides 113a and 113b have a guide portion gp and a support portion sp.

[0103] The width of the guide parts GP becomes narrower as the facing surfaces of the guide parts GP descend, thus guiding the placement of the electronic components ED.

[0104] The support part sp and the guide part gp are integrally formed and the support part sp is located below the guide part gp to support the electronic component ED, thereby forming a support platform sj that sets the placement position of the electronic component ED on the adapter AD.

[0105] And, as Figure 15 As shown, in the movable guides 113a and 113b, there are insertion slots ig that allow the restoring springs 115a and 115 to be inserted. The restoring springs 115a and 115 are configured as restoring components for restoring the position of the movable guides 113a and 113b.

[0106] Preferably, the spacing between a pair of movable guides 113a, 113b is set to accommodate an electronic component ED with the maximum negative tolerance width.

[0107] The pair of fixed guides 114a and 114b have the same shape and structure as the pair of movable guides 113a and 113b, but are fixedly mounted on the mounting frame 116. These fixed guides 114a and 114b can also guide the placement position of the electronic component ED during the placement of the electronic component ED onto the adapter AD. However, the spacing between the pair of fixed guides 114a and 114b is set to accommodate an electronic component ED with the maximum positive tolerance width. Furthermore, the pair of fixed guides 114a and 114b also have the function of preventing the electronic component ED, when placed onto the adapter AD with the adapter AD open by the opener 140, from the perspective of preventing the aforementioned misalignment of the electronic component ED, the pair of fixed guides 114a and 114b can also be named anti-misalignment protrusions for the electronic component ED. For example, if the elastic coefficients of the two restoring springs 115a and 115b become different, the electronic component ED, which descends by moving the handle MH, may deflect to one side. In this case, the fixed guides 114a and 114b will prevent the electronic component ED from deflecting beyond a specified threshold.

[0108] A pair of restoring springs 115a and 115b are configured to return the pair of movable guides 113a and 113b to their original positions when an external force is applied to them, causing them to rotate, and then the external force is removed from them. The lower ends of these restoring springs 115a and 115b are fixed to the mounting frame 116.

[0109] The frame 116 is used to set up a pair of grip rods 111a and 111b, a drive source 112, a pair of movable guides 113a and 113b, a pair of fixed guides 114a and 114b, and restoring springs 115a and 115b.

[0110] Sensor 117 detects improper placement of electronic component AD during the process of placing electronic component ED onto adapter AD.

[0111] Figure 16 An example of adapter AD being placed on shelf 110 is shown. (See reference...) Figure 16 It can be confirmed that the adapter AD has a mobile guide 113a and a fixed guide 114a in the pass area pf.

[0112] <Explanation of characteristic operations>

[0113] When the electronic component ED is supplied to the adapter AD mounted on the shelf 110 by means of the moving handle MH, the adapter AD is kept open by means of the opener 140.

[0114] First, for electronic components ED with the maximum negative tolerance width, the movable guides 113a and 113b will not rotate.

[0115] However, for electronic components ED with a width exceeding the maximum negative tolerance width, if the electronic component ED is lowered by the moving handle MH, external forces are applied to both ends of the electronic component ED along the unfolding direction of the moving guides 113a and 113b simultaneously upon contacting the guide portion gp. Thus, as enlarged... Figure 17 As shown, while the movable guides 113a and 113b rotate and move, the gap between the two support platforms sj is widened, so that the electronic component ED can be properly supported on the two support platforms sj.

[0116] <Application example for shelf>

[0117] Reference Figure 18 The diagram illustrates how the horizontal movement of movable guides 113a and 113b widens or narrows the gap between support platforms.

[0118] In addition, refer to Figure 19 The schematic diagram shows a restoring spring 115 configured to simultaneously provide restoring force to the two movable guides 113a and 113b. Figure 19 As shown, in the example in which a restoring force is applied to both movable guides 113a and 113b by means of a restoring spring 115, the problem that the amount of movement of movable guides 113a and 113b becomes different due to the different elastic coefficients of the restoring springs 115a and 115b can be prevented.

[0119] As described above, although the specific description of the present invention is given with reference to the embodiments in the accompanying drawings, the above embodiments are only examples of preferred embodiments of the present invention. Therefore, it should not be construed that the present invention is limited to the above embodiments, and the scope of the present invention should be understood as the scope of the claims described below and its equivalents.
