[0002] Generally speaking, electronic components are subject to additional quality inspection, sorting, packaging, labeling, loading or storage operations. The equipment that handles electronic components during various operations is called a test handler.

[0003] The test handler can be configured differently according to different purposes. Among various test handlers, one test handler used to help understand is equipped with a shuttle in order to increase the test processing capacity, and the shuttle can transport multiple electronic components at the same time. The electronic components are transported while being loaded on the shuttle, and are transferred to the test socket in the drawer of the tester room cabinet, and are electrically connected to the test socket for testing. The electronic components as test objects are moved to the test handler while being loaded on the customer tray. The customer tray and the shuttle play the role of loading and storing electronic components. In addition, in order to process electronic components, the test handler can also be equipped with an electronic component moving device, which is used to move electronic components between loading components.

[0004] However, in the test handler, there is a possibility that the loading of the electronic components may be improper due to the impact generated by the electronic component moving device during the process of moving the electronic components. For example, there is a concern that the loading state of the electronic components may be disturbed during the process of the electronic components being moved by the electronic component moving device or during the process of loading or unloading the electronic components.

When the loading part lifting plate 242 is lifted and lowered, the loading part gripper 241 may also be lifted and lowered together. The first combined panel JP1, the second combined panel JP2, and the third combined panel JP3 may be coupled to the loading part lifting plate 242. The first combined panel JP1 may couple the upper end of the loading part gripper 241 to the loading part lifting plate 242. The first combined panel JP1 may couple the upper end of the loading part gripper 241 to the loading part lifting plate 242. The loading part confirmation camera 246 may be coupled to the third combined panel JP3. When the loading part lifting plate 242 is lifted and lowered, the loading part gripper 241, the loading part state detector 245, and the loading part confirmation camera 246 may be lifted and lowered together.

[0118] The loading section vertical mover 243 can move the loading section lifting plate 242 in the vertical direction, thereby finally moving the loading section gripper 241 in the vertical direction. The vertical movement of the loading section gripper 241 can mean the vertical movement of the gripping unit 241-1. When the loading section gripper 241 is lowered by the loading section vertical mover 243, the gripping unit 241-1 can be located at a first height capable of gripping or releasing the electronic component ED, and when the loading section gripper 241 is raised by the loading section vertical mover 243, the gripping unit 241-1 can be located at a second height higher than the first height, so that the loading section gripper 241 can be moved in the horizontal direction.

[0119] The loading part horizontal mover 244 may be configured to move the loading part gripper 241 in the horizontal direction. More specifically, the loading part horizontal mover 244 moves the loading part mounting frame 243-4 in the horizontal direction, thereby ultimately being able to move the loading part gripper 241 coupled to the loading part lifting plate 242 in the horizontal direction. To this end, the loading part mounting frame 243-4 is coupled to the loading part horizontal mover 244 in a manner that allows it to be moved in the horizontal direction. For example, when the vertical direction is set as the Z-axis direction, the loading part horizontal mover 244 can move the loading part gripper 241 on a horizontal plane perpendicular to the Z-axis direction, i.e., an XY plane. Of course, the loading part horizontal mover 244 can only move the loading part gripper 241 in the X-axis direction or in the Y-axis direction.

[0120] The loading unit state detector 245 is configured to confirm the loading state of the electronic component ED loaded on the loading element located below the loading unit gripper 241. The loading unit state detector 245 may be provided with a plurality of components coupled to the second coupling panel JP2. The plurality of loading unit state detectors 245 may be configured as distance detection sensors. The plurality of loading unit state detectors 245 can confirm the loading state of the electronic component ED by information about the distance between the loading unit state detector 245 and the electronic component ED loaded on the loading element. For example, when the distance between the loading unit state detector 245 and the electronic component ED is less than or greater than a set value, the controller 500 of the test handler 10 may determine that the loading state of the electronic component ED is poor. The plurality of granular electronic components ED may be loaded on the loading element in a long state in a one-side direction (in the X-axis direction in this embodiment). The plurality of loading unit state detectors 245 may be arranged side by side in the length direction of the electronic component ED, i.e., in the X-axis direction.

[0121] The loading section confirmation camera 246 may be provided to set the teaching point of the loading section gripper 241. For example, the loading section confirmation camera 246 may generate image information by photographing a set point with preset coordinates. Then, the generated image information may be provided to the controller 500. Thus, the controller 500 may analyze and confirm the teaching point of the loading section gripper 241 after finding the position of the set point from the image information. Similarly, the loading section confirmation camera 246 is also coupled to the loading section lifting plate 242 through the third coupling panel JP3, so that it can move in the vertical and horizontal directions together with the loading section lifting plate 242.

[0122] The loading section reader 250 may identify a pallet identifier attached to the customer pallet while the customer pallet is held by the loading section conveyor 230 and moves horizontally. The loading section reader 250 may be disposed on the loading section conveyor 230. The pallet identifier may be a pallet barcode providing information about the customer pallet. The loading section reader 250 may confirm information about the customer pallet by identifying the pallet barcode attached to the side of the customer pallet.

[0123] The loading unit visual detector 260 can receive the electronic component ED from the loading unit hand 240 and can photograph the received electronic component ED. The loading unit visual detector 260 can include a detector base 261, a posture converter 262, a detector camera 263 and an identification code recognizer 264.

[0124] The detector base 261 can support the posture converter 262 and the identification code recognizer 264. The detector base 261 can be a support plate on which the posture converter 262 and the identification code recognizer 264 can be set. A detector hole 261-1 can be formed on the detector base 261. The detector hole 261-1 can be a hole for allowing the detector camera 263 to photograph the electronic component. When the electronic component is photographed by the detector camera 263, the detector hole 261-1 can be located between the electronic component ED and the detector camera 263. When the electronic component ED is positioned so that the detector hole 261-1 is located between the electronic component ED and the detector camera 263, and the surface of the electronic component ED to be photographed faces the detector camera 263, the detector camera 263 can photograph the electronic component ED.

[0125] The posture converter 262 can hold at least a portion of the electronic component ED. The posture converter 262 can change the electronic component ED to two or more different postures while holding the electronic component ED. The posture converter 262 can be disposed on the upper surface of the detector base 261 .

[0126] The detector camera 263 may photograph the electronic component ED along a third direction. The third direction may be a direction orthogonal to the first direction and the second direction. The detector camera 263 may be disposed at the lower side of the detector base 261. The detector camera 263 may photograph the electronic component ED in two or more postures.

[0127] When the first posture converter 262-1 changes the posture of the electronic component ED, the detector camera 263 can shoot any one of the left side or right side of the electronic component ED. When the second posture converter 262-2 changes the posture of the electronic component ED, the detector camera 263 can shoot any one of the front surface, rear surface, upper surface, and lower surface of the electronic component ED. However, for such shooting, the situation of exchanging the electronic component ED from the first posture converter 262-1 to the second posture converter 262-2 can be selectively occurred. In addition, when changing the posture between the first posture converter 262-1 and the second posture converter 262-2, or, when shooting by the detector camera 263, the structure of any one of the posture converters in the first posture converter 262-1 and the second posture converter 262-2 should be avoided so that the first posture converter 262-1 and the second posture converter 262-2 do not interfere with each other.

[0128] The identification code recognizer 264 may be a recognizer capable of recognizing an identification code attached to the electronic component ED. As an example, the identification code recognizer 264 may be a barcode reading camera or a barcode reader capable of recognizing a barcode of an electronic component. The identification code recognizer 264 may be disposed on the detector base 261 in a manner facing the electronic component ED. In order to effectively recognize the identification code of the horizontally moving electronic component ED, the identification code recognizer 264 may be disposed on the detector base 261 in a direction in which the identification code attached to the electronic component ED is observed in an oblique upward direction. While the electronic component ED is horizontally moved by the loading unit hand 240, the identification code recognizer 264 may recognize one or more identification codes (identifiers) attached to the electronic component ED.

The actions in the unloading section conveyor 430 can be performed in the reverse order of the actions in the loading section conveyor. The detailed structure of the unloading section conveyor 430 can correspond to the detailed structure of the loading section conveyor 230.

[0172] The unloading section hand 440 can grasp and transfer the electronic components ED loaded on the shuttle 100 to the customer tray waiting in the loading section fixing plate unit. The actions in the unloading section hand 440 can be performed in the reverse order of the actions in the loading section hand 240. The detailed structure of the unloading section hand 440 can correspond to the detailed structure of the loading section hand 240.

[0173] The unloading unit visual detector 450 can take a post-test image of the tested electronic component ED. The unloading unit visual detector 450 can receive the electronic component ED loaded on the shuttle 100 from the loading unit hand 240. The photographing of the electronic component ED by the unloading unit visual detector 450 can be performed in the same manner as the operation of the loading unit visual detector 260.

[0174] The unloading section shuttle lifting assembly 460 may receive the shuttle 100 moved from the unloading section conveyor 470. The electronic components ED in the shuttle 100 of the unloading section shuttle lifting assembly 460 may be moved to the unloading section visual detector 450 by the unloading section hand 440. The actions in the unloading section shuttle lifting assembly 460 may be performed in a manner opposite to the actions in the loading section shuttle lifting assembly 270. The detailed structure of the unloading section shuttle lifting assembly 460 may correspond to the detailed structure of the loading section shuttle lifting assembly 270.

[0175] The unloading section conveyor 470 can receive the shuttle 100 moved from the shuttle transfer section 300, and can transfer the received shuttle 100 to the unloading section shuttle lifting assembly 460. The action in the unloading section conveyor 470 can be performed in a manner opposite to the action in the loading section conveyor 280. The detailed structure of the unloading section conveyor 470 can correspond to the detailed structure of the loading section conveyor 280.

[0176] The buffer unit 480 can receive a customer tray. The tested electronic component ED can be loaded on the customer tray. The buffer unit 480 may include a buffer frame 481, a first buffer lock 482, and a second buffer lock 483. The buffer frame 481 may be provided in the form of a loading plate capable of receiving a customer tray. A plurality of customer trays may be detachably arranged on the buffer frame 481. When the customer tray is received in the buffer frame 481, the first buffer lock 482 may support a side wall of the edge of the customer tray received on the buffer frame 481. The first buffer lock 482 may be fixedly arranged at one side edge of the buffer frame 481. When the customer tray is received on the buffer frame 481, the second buffer lock 483 may support the other side wall of the edge of the customer tray received on the buffer frame 481. The second buffer lock 483 may be fixedly arranged at the other side edge of the buffer frame 481.

[0177] Controller

[0178] The controller 500 can control the loading section 200, the shuttle transfer section 300, and the unloading section 400 as a whole. For example, the controller 500 can determine the loading status of the electronic components ED loaded on the loading element through the loading section status detector 245. For example, when the distance between the electronic components ED is less than or greater than the set value, the controller 500 can determine that the loading status of the electronic components ED is poor. When the loading section gripper 241 moves, the controller 500 can sequentially confirm the loading status of multiple electronic components ED in this way. When it is confirmed that there are poorly loaded electronic components ED, the administrator can convert the loading status of the multiple poorly loaded electronic components ED to good and restart.

[0179] In addition, the controller 500 can analyze and confirm the teaching point of the loading unit gripper 241 through the loading unit confirmation camera 246. For example, when the loading unit confirmation camera 246 captures a set point with set coordinates and generates image information, the controller 500 can analyze and confirm the teaching point of the loading unit gripper 241 after finding the position of the set point in the image information.

[0180] In addition, the controller 500 can move the insertion clamper 351-2 from the shuttle 100 to the slit formed in the cabinet drawer D in a state where the insertion clamper protrusion 351-203 is engaged with the card slot of the electronic component ED. When the electronic component ED is located in the slit formed in the cabinet drawer D, the controller 500 can release the engagement state between the insertion clamper protrusion 351-203 and the card slot of the electronic component ED, and when the engagement state between the insertion clamper protrusion 351-203 and the card slot of the electronic component ED is released, the insertion clamper 351-2 can be controlled so that the push block 351-204 pushes the upper part of the electronic component ED.

[0181] The slot position of the electronic component ED may be different depending on the type of the electronic component ED. In this regard, the height of the protrusion 351-203 of the insertion clamp 351-2 may be changed by replacing the COK (change over kit), or the protrusion 351-203 of the insertion clamp 351-2 may be changed to a push block 351-204 of different sizes while the protrusion 351-203 of the insertion clamp 351-2 remains unchanged. In addition, it is also possible to deal with it by changing the installation height of the push block 351-204. In addition, a vertical V-groove may be formed on the insertion clamp 351-2 to compensate for the verticality of the electronic component ED, and a through hole and a presence detection sensor portion may be added to one side of the V-groove to detect the presence of the electronic component ED. The push block 351-204 may operate as the following structure, wherein the insertion clamp 351-2 is unfolded at a fixed height above the socket, and after the electronic component ED being grasped is released and freely falls, the top of the electronic component ED is pressed, and finally the socket contacts the terminal of the electronic component ED. In addition, an elastic support portion may be added to the push block 351 - 204 to prevent the electronic component ED or the socket from being damaged due to being pressed above a fixed pressure.

[0182] In addition, the controller 500 can recognize the identification code attached to the electronic component ED through the identification code recognizer 264 and detect the tray identifier of the customer tray through the loading unit reader, thereby being able to confirm the information of the customer tray.

[0183] In addition, the controller 500 can determine whether the electronic component ED is abnormal before and after the tester T by comparing the post-test image of the electronic component ED taken by the unloading part visual detector 450 and the pre-test image of the electronic component ED taken by the loading part visual detector 260.

[0184] The controller can use artificial intelligence (AI) to record, store, transmit and analyze the information of the electronic components, shuttles and customer trays identified by the detector for historical management. The controller can determine whether the electronic components are placed normally, and use artificial intelligence (AI) to learn the judgment results. Based on the results of learning using artificial intelligence (AI), the controller can derive the normal placement position and normal state of the electronic components, shuttles and customer trays, and determine whether the electronic components, shuttles and customer trays are normal based on the calculated results, and learn the judgment results. In addition, the controller 500 can be implemented by a computing device including a microprocessor, a memory, etc., and its implementation method is self-evident to those skilled in the art, so further detailed description is omitted.

[0185] Next, the main structure of a test handler according to an embodiment of the present invention will be described in detail.

[0186] Hands

[0187] Reference Figures 9 to 23 , a plurality of hands involved in an embodiment of the present invention may be provided in the test handler 10. The plurality of hands may include a loading section hand 240 and an unloading section hand 440. The loading section hand 240 may transfer electronic components ED in the loading section 200, and the unloading section hand 440 may transfer electronic components ED in the unloading section 400. The loading section hand 240 may include a loading section gripper 241, a loading section lifting plate 242, a loading section vertical mover 243, a loading section horizontal mover 244, a loading section state detector 245, and a loading section confirmation camera 246. Since the unloading section hand 440 corresponds to the structure of the loading section hand 240, a specific description of the unloading section hand 440 will be omitted.

[0188] The loading part gripper 241 has a plurality of gripping units 241-1, and the gripping units 241-1 are capable of gripping or releasing the gripping of electronic components. The loading part gripper 241 may be provided with eight gripping units 241-1. However, depending on the implementation, the loading part gripper 241 only needs to have at least one or more gripping units 241-1. In addition, the gripping units 241-1 may be configured to grip granular electronic components ED by applying pressure to both ends of the electronic components ED. In particular, the loading part hand 240 may be applicable to the technology of gripping granular electronic components ED. The structure of these gripping units 241-1 will be described in detail in the following sub-catalog.

[0189] The loading part lifting plate 242 may be configured to be able to be lifted and lowered by the loading part vertical mover 243. The loading part gripper 241 may be coupled to the loading part lifting plate 242. When the loading part lifting plate 242 is lifted and lowered, the loading part gripper 241 may also be lifted and lowered together. The first combined panel JP1, the second combined panel JP2, and the third combined panel JP3 may be coupled to the loading part lifting plate 242. The first combined panel JP1 may couple the upper end of the loading part gripper 241 to the loading part lifting plate 242. The first combined panel JP1 may couple the upper end of the loading part gripper 241 to the loading part lifting plate 242. The loading part confirmation camera 246 may be coupled to the third combined panel JP3. When the loading part lifting plate 242 is lifted and lowered, the loading part gripper 241, the loading part state detector 245, and the loading part confirmation camera 246 may also be lifted and lowered together.

[0190] The loading section vertical mover 243 can move the loading section gripper 241 in the vertical direction by moving the loading section lifting plate 242 in the vertical direction. The vertical movement of the loading section gripper 241 means the vertical movement of the gripping unit 241-1. When the loading section gripper 241 is lowered by the loading section vertical mover 243, the gripping unit 241-1 can be located at a first height capable of gripping or releasing the electronic component ED, and when the loading section gripper 241 is raised by the loading section vertical mover 243, the gripping unit 241-1 can be located at a second height higher than the first height, thereby enabling the loading section gripper 241 to move in the horizontal direction.

[0191] In order to move the loading part lifting plate 242 in the vertical direction, the loading part vertical mover 243 may include a loading part lifting motor 243-1, a loading part rotating rod 243-2, a loading part lifting component 243-3, a loading part mounting frame 243-4, a loading part lifting guide rail 243-5a, 243-5b, and a loading part guide rail block 243-6a to 243-6d.

[0192] The loading section elevating motor 243 - 1 may generate power for elevating and lowering the loading section elevating plate 242 .

[0193] The loading section rotating rod 243-2 is rotatably coupled to the loading section mounting frame 243-4. When the loading section lifting motor 243-1 is operated, the rotational force of the loading section lifting motor 243-1 can be transmitted to the loading section rotating rod 243-2 through a transmission structure composed of a belt B and pulleys P1, P2, etc. The loading section rotating rod 243-2 can rotate with a vertical line as the Z-axis direction as a rotation center line C.

[0194] The loading part lifting member 243-3 can be lifted and lowered as the loading part rotating rod 243-2 rotates. The loading part lifting member 243-3 can be coupled to the loading part rotating rod 243-2 by a bolt connection structure. When the loading part rotating rod 243-2 rotates, the loading part lifting member 243-3 can be lifted and lowered by the bolt connection structure.

[0195] The loading part mounting frame 243 - 4 may be provided to be movable in the horizontal direction. Also, the loading part mounting frame 243 - 4 may be movable in the horizontal direction by the loading part horizontal mover 244 .

[0196] The loading part lifting motor 243-1 is arranged on the loading part mounting frame 243-4. When the loading part mounting frame 243-4 moves in the horizontal direction, the loading part lifting motor 243-1 can also move in the horizontal direction. A lifting hole H is formed on the loading part mounting frame 243-4. The loading part lifting component 243-3 and the loading part lifting plate 242 can be combined together through the lifting hole H. That is, the lifting hole H can combine the loading part lifting plate 242 and the loading part lifting component 243-3 with each other across the loading part mounting frame 243-4. Of course, the lifting hole H needs to be formed in a manner that has at least a higher and lower width that is wider than the lifting width of the loading part lifting component 243-3.

[0197] The loading part lifting rails 243-5a, 243-5b and the loading part rail blocks 243-6a to 243-6d can be configured to combine the loading part lifting plate 242 and the loading part mounting frame 243-4 rails together. The loading part lifting rails 243-5a, 243-5b can be combined on the loading part lifting plate 242, and the loading part rail blocks 243-6a to 243-6d can be combined on the loading part mounting frame 243-4. The loading part lifting rails 243-5a, 243-5b and the loading part rail blocks 243-6a to 243-6d can be combined with each other rails. The loading part lifting plate 242 can be lifted and lowered under the guidance of the rail combination structure. Of course, the loading part gripper 241 coupled to the loading part lifting plate 242 is also lifted and lowered together with the lifting and lowering of the loading part lifting plate 242. In addition, when the loading section mounting frame 243 - 4 moves in the horizontal direction, the loading section lifting plate 242 may also move in the horizontal direction together, and thus the loading section gripper 241 coupled to the loading section lifting plate 242 also moves in the horizontal direction together.

[0198] The loading section horizontal mover 244 may be configured to move the loading section gripper 241 in the horizontal direction. More specifically, the loading section horizontal mover 244 may be able to move the loading section gripper 241 coupled to the loading section lifting plate 242 in the horizontal direction by moving the loading section mounting frame 243-4 in the horizontal direction. To this end, the loading section mounting frame 243-4 may be coupled to the loading section horizontal mover 244 in a manner movable in the horizontal direction. For example, when the vertical direction is the Z-axis direction, the loading section horizontal mover 244 may move the loading section gripper 241 on a horizontal plane perpendicular to the Z-axis direction, i.e., an XY plane. Of course, the loading section horizontal mover 244 may also move the loading section gripper 241 only in the X-axis direction, or move the loading section gripper 241 only in the Y-axis direction.

[0199] The loading unit state detector 245 can be configured to confirm the loading state of the electronic component ED loaded on the loading element below the loading unit gripper 241. The loading unit state detector 245 can be configured as a plurality of components coupled to the second coupling panel JP2. The plurality of loading unit state detectors 245 can be configured as distance sensors. The plurality of loading unit state detectors 245 can confirm the loading state of the electronic component ED by information about the distance between the loading unit state detector 245 and the electronic component ED loaded on the loading element. For example, when the distance between the loading unit state detector 245 and the electronic component ED is less than or greater than a set value, the controller 500 of the test handler can determine that the loading state of the electronic component ED is poor. The granular plurality of electronic components ED can be loaded on the loading element in a long state in a one-side direction (in the X-axis direction in this embodiment). The plurality of loading unit state detectors 245 can be arranged side by side in the length direction of the electronic component ED, i.e., in the X-axis direction. According to the present embodiment, during the movement of the loading unit gripper 241 in the Y-axis direction perpendicular to the X-axis direction, the plurality of loading unit state detectors 245 can detect the following information, which is information capable of confirming the loading state of the electronic components ED loaded on the loading element below the loading unit gripper 241 (hereinafter referred to as "state information"). According to the present embodiment, the plurality of loading unit state detectors 245 can be three. Since the plurality of electronic components ED are long in the X-axis direction, three loading unit state detectors 245 can be arranged side by side in the X-axis direction. The loading unit state detector 245 can be coupled to the loading unit lifting plate 242 through the second coupling panel JP2. The loading unit state detector 245 can move in the vertical direction or the horizontal direction together with the loading unit gripper 241.

[0200] The loading section confirmation camera 246 can be configured to set the teaching point of the loading section gripper 241. For example, the loading section confirmation camera 246 can generate image information by photographing a set point with preset coordinates. Then, the generated image information is provided to the controller 500. Thus, the controller 500 can analyze and confirm the teaching point of the loading section gripper 241 after finding the position of the set point in the image information. Similarly, since the loading section confirmation camera 246 is also coupled to the loading section lifting plate 242 through the third coupling panel JP3, it can move in the vertical and horizontal directions together with the loading section lifting plate 242.

[0201] On the other hand, according to the present embodiment, eight gripping units 241-1 may also be provided. All eight gripping units 241-1 may have the same structure. The description of one gripping unit 241-1 is used to replace the description of the remaining gripping units 241-1. The gripping unit 241-1 may include a pair of pressure rods 241-11, 241-12, a loading portion drive motor 241-13, a loading portion drive belt 241-14, a loading portion lifting frame 241-15, a loading portion gripping detector 241-16, a loading portion combining frame 241-17, and a loading portion elevator 241-18.

[0202] The pair of pressure rods 241-11 and 241-12 can move in a direction approaching or moving away from each other (for example, in the X-axis direction). When moving in a direction approaching each other, the pair of pressure rods 241-11 and 241-12 can be in a state of pressing both ends of the electronic component ED to grip. When moving in a direction away from each other, the pair of pressure rods 241-11 and 241-12 can be in a state of releasing the grip of the electronic component ED.

[0203] The loading unit drive motor 241-13 may be configured to move a pair of pressurizing rods 241-11, 241-12. Through the action of the loading unit drive motor 241-13, the pair of pressurizing rods 241-11, 241-12 may move in a direction close to or away from each other. In other words, the loading unit drive motor 241-13 may be configured as a drive source that provides a driving force that enables the pair of pressurizing rods 241-11, 241-12 to grip or release the electronic component ED.

[0204] The loading section drive belt 241-14 may be cyclically rotated along with the operation of the loading section drive motor 241-13. The first pressurizing rod 241-11 may be coupled to one side of the loading section drive belt 241-14, and the second pressurizing rod 241-12 may be coupled to the other side of the loading section drive belt 241-14. Of course, when the loading section drive belt 241-14 is cyclically rotated, one side and the other side may move in opposite directions to each other. When the loading section drive belt 241-14 rotates forward and reversely, the first pressurizing rod 241-11 and the second pressurizing rod 241-12 may be closer to or farther from each other.

[0205] The loading part lifting frame 241-15 can be arranged in a liftable manner. A pair of pressurizing rods 241-11, 241-12, a loading part driving motor 241-13 and a loading part driving belt 241-14 can be arranged on the loading part lifting frame 241-15. The following guide rails GR1, GR2 can be arranged on the loading part lifting frame 241-15, and the guide rails GR1, GR2 are used to guide the movement of the pressurizing rods 241-11, 241-12 when the pressurizing rods 241-11, 241-12 move in the X-axis direction. Guide blocks GB1, GB2 are respectively coupled to the pair of guide rails GR1, GR2. The first pressurizing rod 241-11 can be coupled to the first guide block GB1, and the second pressurizing rod 241-12 can be coupled to the second guide block GB2. When the loading unit driving motor 241-13 is operated, the pressing rods 241-11 and 241-12 can be appropriately moved in the X-axis direction under the guidance of the guide rails GR1 and GR2. In addition, the loading unit lifting frame 241-15 can be provided with a moving block MB for lifting and lowering the loading unit lifting frame 241-15.

[0206] The loading unit gripping detector 241-16 is configured to confirm whether the electronic component ED is gripped by a pair of pressure rods 241-11, 241-12. For example, in FIG17(a), since the loading unit gripping detector 241-16 is in a state of being pressed upward by the electronic component ED, the controller 500 can identify the electronic component ED as being gripped. However, in FIG17(b), since the loading unit gripping detector 241-16 is in a state of not being pressed by the electronic component ED, the controller 500 can identify the electronic component ED as being not gripped. In other words, the controller 500 can confirm whether the gripping action of the electronic component ED is defective during the gripping process based on the information from the loading unit gripping detector 241-16. The loading unit gripping detector 241-16 can be configured to adjust or release the limit switch (not shown) by lifting and lowering.

[0207] The loading unit coupling frame 241-17 can be coupled to the loading unit lifting plate 242. The loading unit coupling frame 241-17 can be provided with a movable guide rail MR, and the movable guide rail MR is used to guide the lifting and lowering movement of the loading unit lifting frame 241-15. The movable guide rail MR is coupled to the upper guide rail of the movable guide rail MR. The loading unit lifting frame 241-15 can be appropriately lifted and lowered under the guidance of the movable guide rail MR. Of course, as the loading unit lifting frame 241-15 is lifted and lowered, a pair of pressure rods 241-11, 241-12, the loading unit driving motor 241-13 and the loading unit driving belt 241-14 are also lifted and lowered together.

[0208] The loading unit elevator 241-18 may be configured to raise and lower a pair of pressure rods 241-11 and 241-12. In the present embodiment, since the loading unit elevator 241-18 raises and lowers the loading unit elevator frame 241-15, the pair of pressure rods 241-11 and 241-12 can be raised and lowered eventually. According to a preferred example, the loading unit elevator 241-18 may be configured as a cylinder. When the piston rod PR is raised and lowered and advanced and retreated along with the action of the loading unit elevator 241-18, the loading unit elevator frame 241-15 can be raised and lowered. The pair of pressure rods 241-11 and 241-12 provided on the loading unit elevator frame 241-15 can also be raised and lowered together. According to the present embodiment, depending on whether each loading unit elevator 241-18 is in action or not, each gripping unit 241-1 can be in a state where it can grip or cannot grip the electronic component ED. That is, even if the loading part gripper 241 is lowered by the loading part vertical mover 243 so that each gripping unit 241-1 is located at the first height at which the electronic components ED can be gripped, each gripping unit 241-1 can selectively grip or not grip the electronic components ED.

[0209] For example, referring to the conceptual diagram of Fig. 19, since the plurality of press rods 241-11 and 241-12 of all the gripping units 241-1 are in a state of being lowered by the loading unit elevator 241-18 in the state (a), all the gripping units 241-1 can grip the electronic components ED. However, in the state (b) of Fig. 17, since the press rods 241-11 and 241-12 of the gripping units 241-1 in the third and fifth columns are in a state of not being lowered, the above two gripping units 241-1 cannot grip the electronic components ED.

[0210] Next, the function and effect of the loading section hand 240 having the above-described structure will be described.

[0211] The loading part gripper 241 includes eight gripping units 241-1. The eight gripping units 241-1 are used to grip both ends of the electronic components ED which are long in the X-axis direction. Three loading part state detectors 245 are also arranged side by side in the X-axis direction.

[0212] In the process of determining whether the electronic component ED is loaded improperly, the loading unit gripper 241 and the loading unit state detector 245 move together in the Y-axis direction. Of course, a plurality of electronic components ED are loaded side by side on the loading element in the Y-axis direction. The loading element is stationary at the unloading position, which is used to unload the electronic component ED from the loading element. That is, when the loading element is stationary at the unloading position, the loading unit hand 240 involved in the present invention performs the action of confirming the loading state of the electronic component ED.

[0213] During the movement of the loading unit gripper 241 in the Y-axis direction, the plurality of loading unit state detectors 245 may be located above the first electronic component ED1. At this time, the plurality of loading unit state detectors 245 detect distance information between the electronic component ED1. The distance information is state information for confirming the loading state of the electronic component ED1. For example, when the electronic component ED is correctly loaded, the first distance information detected by one loading unit state detector 245 is the same as the second distance information detected by another loading unit state detector 245. Furthermore, the first distance information and the second distance information are consistent with the distance values ​​pre-set in the controller 500.

[0214] As shown in FIG. 21(b), in the case where the electronic component ED is tilted, the first distance information and the second distance information are different from each other. Therefore, in the state shown in FIG. 21(b), the electronic component ED cannot be properly gripped by the gripping unit 241-1. Of course, the first distance information and the second distance information are also inconsistent with the set distance value. In addition, even if the first distance information and the second distance information obtained in the state where the electronic component ED is tilted in the Y-axis direction are the same as shown in FIG. 21(c), the first distance information and the second distance information are also inconsistent with the distance value (d) pre-set in the controller 500. Moreover, even if the electronic component ED is floatingly loaded as shown in FIG. 21(d), the first distance information and the second distance information are inconsistent with the set distance value (d). That is, the first distance information and the second distance information are shorter than the distance value (d) pre-registered in the controller 500. Therefore, the controller 500 identifies the remaining states shown in FIG. 21(b), (c), and (d) except the state shown in FIG. 21(a) as poor loading.

[0215] In the manner described above, when the loading portion gripper 241 moves, the loading states of the second to eighth electronic components ED2 to ED8 are sequentially confirmed by the controller 500 .

[0216] Thereafter, at the teaching point, the controller 500 lowers the loading unit gripper 241 through the loading unit vertical mover 243. As a result, each gripping unit 241-1 is lowered from the second height to the first height, thereby being in a state where each electronic component ED can be gripped. In this state, each loading unit elevator 241-18 is actuated, thereby lowering each pressure rod 241-11, 241-12 of each gripping unit 241-1. In this process, each pressure rod 241-11, 241-12 of the gripping unit 241-1 located above the electronic component ED that is confirmed to be poorly loaded is controlled not to be lowered. Therefore, only each electronic component ED that is well loaded can be gripped by the loading unit gripper 241.

[0217] Then, each electronic component ED gripped by the loading unit gripper 241 is moved and loaded onto another loading element. Even in this case, since each pressing rod 241-11, 241-12 on each gripping unit 241-1 can be independently raised and lowered, each electronic component ED can be loaded adjacent to each other on the loading element.

[0218] On the other hand, FIG. 22(a) shows that one loading unit state detector 245 and another loading unit state detector 245 can be used to confirm the loading state of the electronic component ED having the first length D1 specification. Moreover, FIG. 22(b) shows that all three different loading unit state detectors 245 can be used to confirm the loading state of the electronic component ED having the second length D2 specification that is longer than the first length D1. Of course, depending on the implementation, as shown in FIG. 22(c), only one loading unit state detector 245 and another loading unit state detector 245 can be used to confirm the loading state of the electronic component ED having the second length D2 specification.

[0219] That is, according to the present invention, only two loading unit status detectors 245 may be provided, but if the example of providing three loading unit status detectors 245 is followed, it is ensured that the compatibility of the types of electronic components ED that can be processed can be further increased. Further, in the example of FIG. 21 , the loading state of the electronic component ED can be properly confirmed using only one loading unit status detector 245. However, in the case of only one loading unit status detector 245, the proper loading state may not be confirmed in various situations. For example, in Fig.23 In the figure, when the normal loading state is a dotted line and the current loading state of the electronic component ED is a solid line, the same distance is measured by one loading unit state detector 245. Therefore, sometimes it is impossible to confirm that the electronic component ED is loaded improperly. Therefore, it is preferred to set a plurality of loading unit state detectors 245. In particular, as mentioned above, when there are three or more loading unit state detectors 245, the loading state of electronic components ED of different specifications can be confirmed, so there is an advantage of expanding the versatility of the processor.

[0220] As described above, according to the present invention, unlike the conventional technology, when the loading unit gripper 241 moves in the horizontal direction, the loading unit state detector 245 detects the state information while moving in the horizontal direction together with the loading unit gripper 241. In contrast, in the conventional technology, when the loading unit state detector 245 is in a stationary state, the state information is detected while the loading element is moved in the horizontal direction below the loading unit state detector 245. However, the present invention takes into account that when the loading element moves, the impact caused by the movement may cause poor loading of the electronic component ED. Therefore, in the present invention, it is configured that the loading unit state detector 245 detects the state information while moving in the horizontal direction.

[0221] On the other hand, when a part of the eight electronic components ED to be grasped is poorly loaded, various operation methods can be used to move all eight electronic components ED. For example, as described above, it can be set so that the loading unit hand 240 only preferentially grasps and moves the multiple electronic components ED that are well loaded for the first time, and then the administrator converts the loading status of the multiple electronic components ED that are poorly loaded to good, and then moves the remaining multiple electronic components ED for the second time. For example, the controller 500 can also be set to generate a jam when confirming the poorly loaded electronic components ED. At this time, the administrator can restart after converting the loading status of the multiple electronic components ED that are poorly loaded. Thus, it is implemented again to move the multiple electronic components ED after the loading unit hand 240 performs the process of confirming the loading status of the multiple electronic components ED.

[0222] For example, the loading state may become good during the movement. Therefore, it may also be implemented that the loading unit hand 240 first moves the multiple electronic components ED that are well loaded for the first time, and then moves the multiple electronic components ED for the second time from the loading element that returns via a certain circulation path. Here, between the first movement and the second movement, the movement of the electronic components ED loaded on another loading element may also be implemented. That is, it may be implemented that after the multiple electronic components ED that are well loaded are moved for the first time from the front loading element, the electronic components ED that are well loaded are moved from the rear loading element, and then the multiple electronic components ED are moved for the second time from the front loading element that returns again via the circulation path.

[0223] Vision detector

[0224] If you refer to it again Figures 24 to 31, then a plurality of visual detectors involved in one embodiment of the present invention are provided in the test handler. The plurality of visual detectors may include a loading section visual detector 260 and an unloading section visual detector 450. The loading section visual detector 260 may capture a pre-test image of the electronic component ED, and the unloading section visual detector 450 may capture a post-test image of the electronic component ED. The loading section visual detector 260 may include a detector base 261, a posture converter 262, a detector camera 263, and an identification code identifier 264. Since the unloading section visual detector 450 corresponds to the structure of the loading section visual detector 260, the specific description of the unloading section visual detector 450 will be omitted.

[0225] The detector base 261 may support the posture converter 262 and the identification code recognizer 264. The detector base 261 may be a support plate on which the posture converter 262 and the identification code recognizer 264 can be installed. A detector hole 261-1 may be formed on the detector base 261. The detector hole 261-1 may be a hole for allowing the detector camera 263 to photograph the electronic component ED. When the electronic component ED is photographed by the detector camera 263, the detector hole 261-1 may be located between the electronic component ED and the detector camera 263.

[0226] The posture converter 262 can grasp at least a portion of the electronic component ED. The posture converter 262 can change the electronic component ED to more than two postures while grasping the electronic component ED. The posture converter 262 can be disposed on the upper surface of the detector base 261. The posture converter 262 can include a first posture converter 262-1 and a second posture converter 262-2.

[0227] The first posture converter 262-1 can rotate the electronic component ED with the first direction as the center. The first direction can be a direction perpendicular to one side (front or back) of the electronic component ED when the electronic component ED is erected in an upright state by the second posture converter 262-2. The first posture converter 262-1 changes the posture of the electronic component ED by rotating the electronic component ED, so that one of the left side or right side of the electronic component ED can be directed to the detector camera 263. The first posture converter 262-1 may include a first detector bracket 262-11, a first detector clamp 262-21, a first detector lifting guide rail 262-13, a first detector rotating ring 262-14, a first detector rotating motor 262-15, a first detector transfer guide rail 262-16 and a first detector transfer device 262-17.

[0228] The first detector bracket 262-11 can support the first detector rotating motor 262-15. The first detector bracket 262-11 can be slidably disposed on the first detector lifting rail 262-13. The first detector bracket 262-11 can move on the first detector lifting rail 262-13 in a direction away from or close to the detector hole 261-1 of the detector base 261.

[0229] The first detector clamp 262-21 can grasp the long side of the electronic component ED. In this embodiment, when the electronic component ED is erected in an upright state by the second posture converter 262-2, the long side of the electronic component ED can be the upper surface and the lower surface of the electronic component ED. The first detector clamp 262-21 can be set to be a plurality of mutually opposed. A plurality of first detector clamps 262-21 can be arranged opposite to the electronic component ED in a straight line so as to grasp the long side of the electronic component ED from the upper side and the lower side. Detector grooves 262-121 can be formed on the plurality of first detector clamps 262-21, respectively. The detector groove 262-121 can be formed in a V-shaped groove shape in which the long side of the electronic component ED is fixed to achieve line contact. A plurality of first detector clamps 262-21 can be arranged on the first detector lifting rail 262-13 in a slidable manner. The plurality of first detector grippers 262 - 21 move on the first detector lifting rail 262 - 13 in directions away from or approaching each other, thereby being able to selectively grip the long sides of the electronic components ED.

[0230] The first detector lifting rail 262-13 may provide a plurality of paths for the first detector holder 262-21 to move. A plurality of first detector holders 262-21 may be slidably disposed on the first detector lifting rail 262-13. The first detector lifting rail 262-13 may be fixedly disposed on the first detector rotating ring 262-14. When the first detector rotating ring 262-14 rotates, the first detector lifting rail 262-13 may rotate in a manner linked to the detector rotator.

[0231] The first detector rotating ring 262-14 can rotate the first detector holder 262-21 through the action of the first detector rotating motor 262-15. The first detector rotating ring 262-14 can be drivingly connected to the rotating shaft of the first detector rotating motor 262-15. When the first detector rotating motor 262-15 is in action, the first detector rotating ring 262-14 can receive the rotating force from the first detector rotating motor 262-15 and transmit it to the first detector holder 262-21.

[0232] The first detector rotating motor 262-15 can rotate the first detector rotating ring 262-14. The first detector rotating ring 262-14 can be rotated between 90 degrees and -90 degrees or between 0 degrees and 270 degrees by the first detector rotating motor 262-15. If the rotation range of the first detector rotating ring 262-14 is set to rotate between 0 degrees and 270 degrees, the rotation range of the first detector rotating ring 262-14 may be smaller than the rotation range of the second detector rotating ring 262-20. The first detector rotating motor 262-15 can rotate the first detector rotating ring 262-14 by ±90 degrees so that one of the left side surface or the right side surface of the electronic component ED faces the detector camera 263. As an example, when the plurality of first detector clamps 262-21 grasp the upper and lower surfaces of the electronic component ED erected in an upright state, the first detector rotating motor 262-15 rotates the first detector rotating ring 262-14 by +90 degrees in one direction, at which time the detector camera 263 can photograph one side of the left side or right side of the electronic component ED (the left side as an example). In addition, when the plurality of first detector clamps 262-21 grasp the upper and lower surfaces of the electronic component ED erected in an upright state, the first detector rotating motor 262-15 rotates the first detector rotating ring 262-14 by -90 degrees in the other direction, at which time the detector camera 263 can photograph the other side of the left side or right side of the electronic component ED (the right side as an example).

[0233] The first detector transfer rail 262-16 may provide a path for the first detector bracket 262-11 to move. The first detector bracket 262-11 may be slidably disposed on the first detector transfer rail 262-16. The first detector transfer rail 262-16 may be fixedly disposed on the detector base 261. The first detector transfer rail 262-16 may guide the first detector bracket 262-11 in a direction away from or close to the detector hole 261-1 of the detector base 261.

[0234] The first detector transporter 262-17 may move the first detector support 262-11 on the first detector transport rail 262-16. The first detector transporter 262-17 may be connected to the first detector support 262-11. The first detector transporter 262-17 may move the first detector holder 262-21 in a direction away from or close to the detector hole 261-1 of the detector base 261 by moving the first detector support 262-11. As an example, when the second detector holder 262-22 of the second posture converter 262-2 grasps the electronic component ED, the first detector transporter 262-17 moves the first detector holder 262-21 in a direction away from the detector hole 261-1 of the detector base 261, thereby preventing interference between the electronic component ED and the first detector holder 262-21. When the electronic component ED is to be grasped by the first detector holder 262 - 21 , the first detector transfer device 262 - 17 can move the first detector holder 262 - 21 toward the direction close to the detector hole 261 - 1 of the detector base 261 .

[0235] The second posture converter 262-2 can rotate the electronic component ED with the second direction as the center. The second direction can be a direction horizontally orthogonal to the first direction. The second posture converter 262-2 can convert the posture of the electronic component ED by rotating the electronic component ED, so that one of the front surface, rear surface, upper surface, and lower surface of the electronic component ED can be directed toward the detector camera 263. The second posture converter 262-2 can be arranged on the detector base 261 so as to be located in a direction orthogonal to the second posture converter 262-2. The second posture converter 262-2 may include a second detector bracket 262-21, a second detector clamp 262-22, a second detector rotating motor 262-23, a second detector transfer device 262-24, and a second detector conveyor 262-25.

[0236] The second detector bracket 262-21 can support the second detector rotating motor 262-23. The second detector bracket 262-21 can move on the detector base 261. In this embodiment, the second detector bracket 262-21 can be slidably disposed on a guide rail disposed on the detector base 261. The guide rail can provide a path for the second detector bracket 262-21 to move. The second detector bracket 262-21 can move on the guide rail in a direction away from or close to the detector hole 261-1 of the detector base 261.

[0237] The second detector clamp 262-22 can grasp the short side of the electronic component ED. In this embodiment, when the electronic component ED is erected into an upright state by the second posture converter 262-2, the short sides of the electronic component ED can be the two side surfaces of the electronic component ED. The second detector clamp 262-22 can be set to be multiple and opposite to each other. Multiple second detector clamps 262-22 can be arranged in a straight line relative to the electronic component ED so as to grasp the short side of the electronic component ED. Multiple second detector clamps 262-22 can be arranged on the second detector lifting rail in a slidable manner. Multiple second detector clamps 262-22 move in a direction away from or close to each other on the second detector lifting rail, so as to selectively grasp the short side of the electronic component ED.

[0238] The second detector rotating ring 262-20 can rotate the second detector holder 262-22 by the action of the second detector rotating motor 262-23. The second detector rotating ring 262-20 can be drivingly connected to the rotating shaft of the second detector rotating motor 262-23. When the second detector rotating motor 262-23 is actuated, the second detector rotating ring 262-20 can receive the rotational force from the second detector rotating motor 262-23 and transmit it to the second detector holder 262-22. The second detector rotating ring 262-20 can rotate between 0 degrees and 360 degrees or between 0 degrees and -360 degrees by the second detector rotating motor 262-23.

[0239] The second detector rotating ring 262-20 can rotate the second detector clamp 262-22. The second detector rotating ring 262-20 can rotate the second detector clamp 262-22 by ±90 degrees or ±180 degrees so that any one of the left side or right side of the electronic component ED faces the detector camera 263. As an example, when a plurality of second detector clamps 262-22 grasp both ends of the electronic component ED erected in an upright state, the detector camera 263 can photograph the lower surface of the electronic component ED. In addition, if the second detector rotating ring 262-20 rotates the second detector clamp 262-22 by +90 degrees or -90 degrees in a state where a plurality of second detector clamps 262-22 grasp both ends of the electronic component ED erected in an upright state, the detector camera 263 can photograph the front surface or the rear surface of the electronic component ED. In addition, if the second detector rotating ring 262-20 rotates the second detector clamp 262-22 by +180 degrees or -180 degrees while multiple second detector clamps 262-22 grasp the two ends of the electronic component ED erected in an upright state, the detector camera 263 can photograph the upper surface of the electronic component ED.

[0240] The second detector transporter 262-24 can move the second detector bracket 262-21. In this embodiment, the second detector transporter 262-24 can transport the second detector bracket 262-21 through the guide rail. The first detector transporter 262-17 can move the first detector holder 262-21 in a direction away from or close to the detector hole 261-1 of the detector base 261 by moving the first detector bracket 262-11. As an example, when the electronic component ED is to be grasped by the second detector holder 262-22, the second detector transporter 262-24 can move the second detector holder 262-22 in a direction close to the detector hole 261-1 of the detector base 261. In addition, when the first detector holder 262 - 21 of the first posture converter 262 - 1 grasps the electronic component ED, the second detector transporter 262 - 24 can move the second detector holder 262 - 22 in a direction away from the detector hole 261 - 1 of the detector base 261 .

[0241] The second detector conveyor 262-25 can be driven and connected to the second detector transfer device 262-24. The second detector conveyor 262-25 can be set to a ring shape. The second detector conveyor 262-25 can be connected to a pair of second detector brackets 262-21 through a top conveyor sheet 262-251 and a bottom conveyor sheet 262-252. The top conveyor sheet 262-251 can be connected to the upper conveyor of the second detector conveyor 262-25 and any one of the pair of second detector brackets 262-21. The bottom conveyor sheet 262-252 can be connected to the lower conveyor of the second detector conveyor 262-25 and the other second detector bracket 262-21 of the pair of second detector brackets 262-21. When the second detector conveyor 262-25 is circulated by the action of the second detector transfer device 262-24, the top conveyor sheet 262-251 and the bottom conveyor sheet 262-252 can move the same distance toward or away from each other. When the top conveyor sheet 262-251 and the bottom conveyor sheet 262-252 move toward or away from each other, since a pair of second posture converters 262-2 also move toward or away from each other through the top conveyor sheet 262-251 and the bottom conveyor sheet 262-252, the electronic component ED can be grasped or released by the second posture converter 262-2.

[0242] The detector camera 263 can shoot the electronic component ED along the third direction. The third direction can be a direction orthogonal to the first direction and the second direction. The detector camera 263 can be set on the lower side of the detector base 261. The detector camera 263 can shoot the electronic component ED in two or more postures. The detector camera 263 may include a detector shooting part 263-1 and a focus moving part 263-2. The detector shooting part 263-1 may be a camera for shooting the electronic component ED. The detector shooting part 263-1 may be set toward the detector hole 261-1 of the detector base 261. The focus moving part 263-2 may be an actuator that can lift the detector shooting part 263-1. The focus moving part 263-2 can adjust the focus of the detector shooting part 263-1 relative to the electronic component ED by lifting the detector shooting part 263-1. The focus distance of the detector shooting part 263-1 may vary according to the type of the electronic component ED and the spacing distance between the electronic component ED. Therefore, when the detector imaging section 263 - 1 is appropriately raised and lowered by the focus moving section 263 - 2 , the focus of the detector imaging section 263 - 1 with respect to the electronic component ED can be accurately aligned.

[0243] When the first posture converter 262-1 converts the posture of the electronic component ED, the detector camera 263 can photograph any of the left side or right side of the electronic component ED. When the second posture converter 262-2 converts the posture of the electronic component ED, the detector camera 263 can photograph any of the front surface, rear surface, upper surface, and lower surface of the electronic component ED.

[0244] The identification code recognizer 264 may be a recognizer capable of recognizing an identification code attached to the electronic component ED. As an example, the identification code recognizer 264 may be a barcode reading camera or a barcode reader capable of recognizing a barcode of the electronic component ED. The identification code recognizer 264 may be disposed on the detector base 261 in a manner facing the electronic component ED. In order to effectively recognize the identification code of the electronic component ED moving in the horizontal direction, the identification code recognizer 264 may be disposed on the detector base 261 in a manner of observing the identification code attached to the electronic component ED in an oblique upward direction.

[0245] Next, the operation and effect of the loading portion visual detector having the structure as described above will be described.

[0246] The loader visual detector 260 may receive the electronic component ED through the loader hand 240 , and may change the received electronic component ED into two or more postures to photograph the electronic component ED.

[0247] For example, if you refer again to Fig.28, the second posture converter 262-2 can enable the loading section hand 240 to receive the electronic component ED from the loading section visual detector 260. When the loading section hand 240 positions the electronic component ED between the pair of second detector grippers 262-22, the second detector transfer 262-24 enables the second detector grippers 262-22 to grip the electronic component ED by moving the pair of second detector grippers 262-22 toward each other. When the second detector grippers 262-22 grip the electronic component ED, the first detector transfer 262-17 of the first posture converter 262-1 can prevent interference between the electronic component ED and the first detector gripper 262-21 by moving the first detector gripper 262-21 toward a direction away from the detector hole 261-1 of the detector base 261.

[0248] When the electronic component ED is gripped by the second detector clamp 262-22 of the second posture converter 262-2, in other words, when multiple second detector clamps 262-22 grip the short sides of the electronic component ED erected in an upright posture, the detector camera 263 can photograph the lower surface of the electronic component ED.

[0249] If you refer to it again Fig.29 In a state where the plurality of second detector holders 262-22 hold both ends of the electronic component ED erected in an upright state, the second detector rotating motor 262-23 rotates the second detector holder 262-22 by +90 degrees or -90 degrees, and the detector camera 263 can photograph the front surface or the rear surface of the electronic component ED. In addition, in a state where the plurality of second detector holders 262-22 hold both ends of the electronic component ED erected in an upright state, the second detector rotating motor 262-23 rotates the second detector holder 262-22 by +180 degrees or -180 degrees, and the detector camera 263 can photograph the upper surface of the electronic component ED.

[0250] If you refer to it again Fig.30 The first detector conveyor 262-17 of the first posture converter 262-1 can move the first detector clamp 262-21 in a direction away from the detector hole 261-1 of the detector base 261, and the first detector clamp 262-21 can grasp the long side of the electronic component ED by moving in a direction close to each other on the first detector lifting rail 262-13. When the electronic component ED is grasped by the first posture converter 262-1, the second detector conveyor 262-24 of the second posture converter 262-2 can release the second detector clamp 262-22 from grasping the electronic component ED by moving the pair of second detector clamps 262-22 in a direction away from each other.

[0251] If you refer to it again Fig.31 When the first detector gripper 262-21 of the first posture converter 262-1 grasps the long side of the electronic component ED, if the first detector rotating motor 262-15 rotates the first detector rotating ring 262-14 by +90 degrees or -90 degrees, the detector camera 263 can shoot the left side or right side of the electronic component ED. When the shooting of the electronic component ED is finished, the actions of the first posture converter 262-1 and the second posture converter 262-2 as described above can be performed in reverse order, and the electronic component ED grasped by the second posture converter 262-2 can be moved to the next moving position by the loading unit hand 240.

[0252] Shuttle lift assembly

[0253] When referring to Figure 32 to Figure 38 When the shuttle lifting assembly involved in one embodiment of the present invention is provided in plurality. The plurality of shuttle lifting assemblies may include a loading section shuttle lifting assembly 270 and an unloading section shuttle lifting assembly 460. The loading section shuttle lifting assembly 270 may move the shuttle 100 of the loading section toward the shuttle transfer section 300. The unloading section shuttle lifting assembly 460 may move the shuttle 100 of the shuttle transfer section 300 to the unloading section. The shuttle 100 may circulate along a path returning to the loading section shuttle lifting assembly 270 via the loading section shuttle lifting assembly 270, the unloading section shuttle lifting assembly 460, and the transfer conveyor 310. The loading section shuttle lifting assembly 270 may include a lifting guide rail 271, a first shuttle lift 272, a second shuttle lift 273, and a shuttle slide mover 274. Since the unloading section shuttle lifting assembly 460 corresponds to the structure of the loading section shuttle lifting assembly 270, the specific description of the unloading section shuttle lifting assembly 460 will be omitted.

[0254] The lifting guide 271 may guide the shuttle 100 to the first shuttle position S1 or the second shuttle position S2 located on the same horizontal line. The first shuttle position S1 may be a position where the shuttle 100 moving upward from the first shuttle elevator 272 is located. The first shuttle position S1 may be located on the same vertical line as the path where the shuttle 100 is lifted and lowered in the first shuttle elevator 272. The second shuttle position S2 may be a position where the shuttle 100 moving downward through the second shuttle elevator 273 is located. The second shuttle position S2 may be located on the same vertical line as the path where the shuttle 100 is lifted and lowered in the second shuttle elevator 273. The first shuttle position S1 and the second shuttle position S2 may be located on the same horizontal plane. The lifting guide 271 may include a lifting support table 271-1, a guide unit 271-2, a fixed stopper 271-3, and a discharge stopper 271-4.

[0255] The lifting support platform 271-1 may be provided as a pair arranged side by side. A lifting space may be provided between the pair of lifting support platforms 271-1. The guide unit 271-2, the fixed stopper 271-3, and the discharge stopper 271-4 may be provided on the lifting support platform 271-1. On one lifting support platform 271-1, a pair of fixed stoppers 271-3 and a pair of discharge stoppers 271-4 may be provided in the form of a mirror surface.

[0256] The guide unit 271-2 may selectively support the shuttle 100. The guide unit 271-2 may be disposed on the lower surface of the lifting support table 271-1. The guide unit 271-2 may include a guide sheet 271-21, a guide actuator 271-22, a first guide roller 271-23, a second guide roller 271-24, and an elastic roller 271-25.

[0257] The guide piece 271-21 may be configured to be a plurality of guide pieces 271-21 disposed on the lower surface of the lifting support platform 271-1 so as to be disposed on one side and the other side of the lifting space. As an example, the guide piece 271-21 may include a pair of first guide pieces 271-21a and second guide pieces 271-21b disposed on the lifting support platform 271-1 in a mutually opposing manner. A lifting space may be formed between the first guide piece 271-21a and the second guide piece 271-21b. The first guide piece 271-21a and the second guide piece 271-21b may be moved in a manner close to or away from the lifting space by the guide actuator 271-22.

[0258] The guide actuator 271-22 can selectively move the guide piece 271-21 into or out of the lifting space. As an example, when any one of the pair of guide pieces 271-21 is in a stationary state, the guide actuator 271-22 can move the other guide piece 271-21 of the pair of guide pieces 271-21 into or out of the lifting space, so that both of the pair of guide pieces 271-21 can move into or out of the lifting space.

[0259] The first guide roller 271-23 may be provided at the end of the guide piece 271-21. The first guide roller 271-23 may freely rotate at the end of the guide piece 271-21 to support the lower surface of the shuttle 100. The rotation axis of the first guide roller 271-23 may be in a horizontal direction. When the shuttle 100 is located at the first shuttle position S1 or the second shuttle position S2, the first guide roller 271-23 may support the lower surface of the shuttle 100.

[0260] The second guide roller 271-24 may be disposed on the upper surface of the guide piece 271-21. The second guide roller 271-24 may freely rotate on the upper surface of the guide piece 271-21 to support the side wall of the shuttle 100. The rotation axis of the second guide roller 271-24 may be perpendicular to the rotation axis of the first guide roller 271-23. When the shuttle 100 is located at the first shuttle position S1 or the second shuttle position S2, the second guide roller 271-24 may support the side wall of the shuttle 100.

[0261] The elastic roller 271-25 may provide an elastic force for pressing the side wall of the shuttle 100. The elastic roller 271-25 may be provided on the guide sheet 271-21. When the shuttle 100 is located at the first shuttle position S1 or the second shuttle position S2, the elastic roller 271-25 may provide an elastic force to push the shuttle 100 when the shuttle 100 abuts against the guide sheet 271-21.

[0262] The fixed stopper 271-3 can guide the arrangement of the shuttle 100 at the first shuttle position S1 or the second shuttle position S2. The fixed stopper 271-3 can be located at the end of the lifting space. The fixed stopper 271-3 can be set on at least any one of the pair of lifting support platforms 271-1. In a state where the shuttle 100 is located at the first shuttle position S1 or the second shuttle position S2, when the discharge stopper 271-4 presses one end side of the shuttle 100, the fixed stopper 271-3 can support the other end side of the shuttle 100. The fixed stopper 271-3 can have a substantially " " shape.

[0263] When the shuttle 100 is located at the first shuttle position S1 or the second shuttle position S2, the discharge type stopper 271-4 can push the end side of the shuttle 100. The discharge type stopper 271-4 can be provided on any one of the pair of lifting support tables 271-1. Since the end of the discharge type stopper 271-4 is formed to be inclined, when the discharge type stopper 271-4 pushes the end side of the shuttle 100, the shuttle 100 can be easily attached to the fixed type stopper 271-3. For example, when the shuttle 100 is located at the first shuttle position S1 or the second shuttle position S2, when the discharge-type stopper 271-4 presses one end side of the shuttle 100, the other end side of the shuttle 100 will be tightly attached to the fixed-type stopper 271-3, thereby enabling the shuttle 100 to be arranged at the correct position of the first shuttle position S1 or the second shuttle position S2.

[0264] The first shuttle elevator 272 can lift the shuttle 100 from the first shuttle position S1. The first shuttle elevator 272 can lift the shuttle 100 from the first shuttle position S1 by a first lifting distance.

The first shuttle support frame 272-3 may be fixedly disposed on the first shuttle lifting piece 272-2.

[0267] The first shuttle support frame 272-3 may support the lower surface of the shuttle 100. Since the first shuttle support frame 272-3 supports the center portion of the lower surface of the shuttle 100, it is possible to provide a space in which the guide unit 271-2 can support both sides of the shuttle 100 when the shuttle 100 is located at the first shuttle position S1 or the second shuttle position S2. The first shuttle support frame 272-3 may be bent and connected to the same horizontal plane as the first shuttle lifting piece 272-2. The end of the first shuttle support frame 272-3 may be extended to the end portion of the shuttle 100 relative to the center portion of the lower surface of the shuttle 100.

[0268] The second shuttle elevator 273 can lift the shuttle 100 from the second shuttle position S2.

[0270] The second shuttle lifting piece 273-2 can be slidably disposed on the second shuttle lifting rail 273-1. When the second shuttle lifting piece 273-2 is lifted and lowered on the second shuttle lifting rail 273-1, the second shuttle support frame 273- is also lifted and lowered together with the second shuttle lifting piece 273-2. The second shuttle support frame 273- is fixedly disposed on the second shuttle lifting piece 273-2.

[0271] The second shuttle support frame 273- can support the lower surface of the shuttle 100. Since the second shuttle support frame 273- supports the center portion of the lower surface of the shuttle 100, it is possible to provide a space in which the guide unit 271-2 can support both sides of the shuttle 100 when the shuttle 100 is located at the second shuttle position S2 or the second shuttle position S2. The second shuttle support frame 273- is bent and connected to the same horizontal plane as the second shuttle lifting piece 273-2. The end of the second shuttle support frame 273- can be extended to the end portion of the shuttle 100 relative to the center portion of the lower surface of the shuttle 100.

[0272] The shuttle slide mover 274 can move the shuttle 100 between the first shuttle position S1 and the second shuttle position S2. The shuttle slide mover 274 may include a first shuttle slide rail 274-1, a first shuttle slide moving piece 274-2, a second shuttle slide rail 274-3, a second shuttle slide moving piece 274-4, and a shuttle moving pin 274-5.

[0273] The first shuttle sliding guide rail 274-1 may provide a moving path for the first shuttle sliding moving piece 274-2. The first shuttle sliding guide rail 274-1 may guide the first shuttle sliding moving piece 274-2 in the length direction of the lifting support platform 271-1. The first shuttle sliding guide rail 274-1 may be extended to a position corresponding to the first shuttle position S1 and the second shuttle position S2. The first shuttle sliding guide rail 274-1 may be configured to enable the first shuttle sliding moving piece 274-2 to slide.

[0274] The first shuttle sliding moving piece 274-2 can slide along the first shuttle sliding guide rail 274-1, so that the second shuttle sliding guide rail 274-3 can be moved to the first shuttle position S1 or the second shuttle position S2. The bottom of the first shuttle sliding moving piece 274-2 can be in the shape of a guide groove that can slide along the first shuttle sliding guide rail 274-1. The shuttle 100 sliding guide rail is set on the top of the first shuttle sliding moving piece 274-2.

[0275] The second shuttle slide rail 274-3 may provide a moving path of the second shuttle slide moving piece 274-4. The second shuttle slide rail 274-3 may be disposed on the first shuttle slide moving piece 274-2 in a direction intersecting with the first shuttle slide rail 274-1.

[0276] The second shuttle sliding moving piece 274-4 can move in a direction away from or close to the lifting space. Since the second shuttle sliding moving piece 274-4 can slide along the second shuttle sliding guide rail 274-3, the shuttle moving pin 274-5 can be moved to the shuttle engagement groove 111 of the shuttle 100. The bottom of the second shuttle sliding moving piece 274-4 can be in the shape of a guide groove that can slide along the second shuttle sliding guide rail 274-3.

[0277] The shuttle moving pin 274-5 can selectively fix the shuttle 100. When the shuttle 100 is located at the first shuttle position S1 or the second shuttle position S2, the shuttle moving pin 274-5 can be selectively inserted into the shuttle engagement groove 111 of the shuttle 100 by the movement of the second shuttle sliding moving piece 274-4. As an example, the shuttle moving pin 274-5 can be in the shape of a protrusion that can be inserted into the shuttle engagement groove 111 of the cabinet shuttle 100. In a state where the shuttle moving pin 274-5 is inserted into the shuttle engagement groove 111 of the shuttle 100, when the first shuttle sliding moving piece 274-2 moves along the first shuttle sliding guide 274-1, the shuttle 100 can move from the first shuttle position S1 to the second shuttle position S2, or, from the second shuttle position S2 to the first shuttle position S1.

[0278] Next, the function and effect of the loading section shuttle lifting assembly having the above-mentioned structure will be described.

[0279] When the shuttle 100 is located at the first shuttle position S1 of the lifting guide rail 271, the shuttle 100 is arranged at the first shuttle position S1 by the guide unit 271-2, the fixed stopper 271-3 and the discharge stopper 271-4. The first guide roller 271-23 and the second guide roller 271-24 of the guide unit 271-2 can support the lower surface and the side wall of the shuttle 100 at the first shuttle position S1, and the elastic roller 271-25 can press the side wall of the shuttle 100 so that the shuttle 100 can be closely attached to the guide piece 271-21. In addition, when the shuttle 100 is located at the first shuttle position S1 of the lifting rail 271, the discharge type stopper 271-4 pushes the end side of the shuttle 100 to make the shuttle 100 close to the fixed type stopper 271-3, so that the shuttle 100 can be arranged at the correct position of the first shuttle position S1. When the shuttle 100 is arranged at the correct position of the first shuttle position S1, the loading section hand 240 can load the electronic component ED on the shuttle 100. When the electronic component ED is loaded on the shuttle 100, the shuttle 100 is moved from the first shuttle position S1 to the second shuttle position S2 by the shuttle slide mover 274.

[0280] When the shuttle 100 is located at the second shuttle position S2 of the lifting rail 271, the shuttle 100 moves downward to the first loading section conveyor 281 through the second shuttle lift 273. When the shuttle 100 moves to the first loading section conveyor 281, the shuttle 100 is moved to the first transfer conveyor 311 of the shuttle transfer section 300 through the first loading section conveyor 281.

[0281] On the other hand, the shuttle 100 may be located at the lower side of the first shuttle position S1 by the second loading part conveyor 282. The shuttle 100 may be moved upward from the second loading part conveyor 282 to the first shuttle position S1 of the lifting rail 271 by the first shuttle elevator 272. When the shuttle 100 is located at the first shuttle position S1 of the lifting rail 271, the shuttle 100 repeats the arrangement posture at the first shuttle position S1 by the guide unit 271-2, the fixed type stopper 271-3, and the discharge type stopper 271-4.

In this way, the insertion hand 350 can be moved to the prescribed teaching position, and the cabinet drawer D can be grasped or released by accurate lifting and lowering movement. That is, when the horizontality of the drawer D is distorted, not only the verticality of the socket existing inside it is distorted, but also the socket direction in the direction perpendicular to the above horizontality is distorted, so it must be aligned. Therefore, the shape of the first plate pin 348-11 and the second plate pin 348-21 is roughly the same as the rectangular shape, preferably a graphic shape with a predetermined angle.

[0353] The board-type communicator may be a transceiver capable of communicating with the lock portion of the cabinet drawer D. The lock portion of the cabinet drawer D may be a locking device capable of selectively locking or unlocking the cabinet drawer D on the tester T. When the board body 341 is located in front of the cabinet drawer D, the board-type communicator may transmit a signal for unlocking the cabinet drawer D to the lock portion of the cabinet drawer D. When the lock portion of the cabinet drawer D receives the unlocking signal from the board-type communicator, the cabinet drawer D may be unlocked.

[0354] In addition, the board communicator can transmit a signal to the tester T to open the test door of the tester T whose cabinet drawer D is pulled out or not exposed through the door. For example, among multiple cabinet drawers D, after the test of the electronic component ED is completed in a certain cabinet drawer D, the board feeder 340 can move to the test door of the tester T where the certain cabinet drawer D is located, and the board communicator can open the tester door of the tester T by transmitting a signal for opening the tester door to the tester T.

[0355] A signal may be received from the tester T indicating whether the test door of the tester T is opened, indicating that the cabinet drawer D is pulled out or not exposed through the door.

[0356] In this way, interference or collision with the door can be prevented, or it can be used as information for selecting the action position. When the door is opened, based on the signal, the plate feeder is ready to move, and the drawer of the cabinet will be discharged during the movement, making the logistics process faster. In the absence of a door, if the signal of the entry and exit information of the cabinet drawer is received or the cabinet drawer is tested, a discharge command can be sent to the tester before or after the plate feeder approaches. In addition, if it is not a drawer form, but the socket is exposed to the outside and the socket can be seen from the front, information about whether the test is completed can be received, so that the action position and action sequence can be determined, and information about the electronic components that will be received from the socket of the cabinet can be transmitted to the tester, and real-time history management can be performed.

[0357] Hereinafter, the operation and effect of the plate feeder having the above-mentioned structure will be described.

[0358] The plate feeder 340 can be moved to the vicinity of a designated cabinet drawer D to be pulled out in the test among the plurality of cabinet drawers D. The plate feeder 340 can be moved to a position corresponding to a designated cabinet drawer D's left-right direction point by a plate left-right direction mover 342. In addition, the plate feeder 340 can be moved to a position corresponding to a designated cabinet drawer D's up-down direction point by a plate up-down direction mover 343.

[0359] When the plate feeder 340 moves to the point where the designated cabinet drawer D is located, the slide feeder 345 can pull out the designated cabinet drawer D from the tester T, or push the designated cabinet drawer D into the tester T. In the case where the slide feeder 345 pulls out the cabinet drawer D from the tester T, the first slide feeder 345-1 moves toward the cabinet drawer D on the plate body 341 through the action of the slide motor 346, and when the first plate protrusion 345-14 is located at the lower side of the engagement groove of the cabinet drawer D, the first plate feeder part 345-11 of the first slide feeder 345-1 can engage the first plate protrusion 345-14 with the engagement groove of the cabinet drawer D through the upward movement of the first plate lifting part 345-13. In a state where the first sliding feeder 345-1 limits the engagement groove of the cabinet drawer D by the first plate-type protrusion 345-14, the cabinet drawer D can be moved toward the plate body 341 by the action of the sliding motor 346. When the first sliding feeder 345-1 moves to a point where the first plate-type protrusion 345-14 and the second plate-type protrusion 345-24 are located on the same line, the first plate-type protrusion 345-14 can be disengaged from the engagement groove of the cabinet drawer D by the upward movement of the first plate-type lifting part 345-13. At this time, the first plate-type protrusion 345-14 and the second plate-type feeder part 345-21 can be placed in a straight line in the left-right direction at a predetermined reference position. That is, the first plate-type protrusion 345-14 and the second plate-type feeder part 345-21 can overlap in the left-right direction at a predetermined reference position. Thereafter, the second plate protrusion 345-24 of the second slide feeder 345-2 can engage with the engagement groove of the cabinet drawer D through the upward movement of the second plate lifter 345-23. When the second plate protrusion 345-24 restricts the engagement groove of the cabinet drawer D, the second slide feeder 345-2 can move the cabinet drawer D to a point where it completely overlaps the upper side of the plate body 341 through the action of the sliding motor 346.

[0360] When the cabinet drawer D moves to a point where it completely overlaps the upper side of the plate body 341, the plate lifting unit 348 can adjust the height of both sides of the cabinet drawer D to maintain the balance of both sides of the cabinet drawer D. In other words, when the plate pin slot of the cabinet drawer D is located at a point corresponding to the first plate pin 348-11 and the second plate pin 348-21 of the plate lifting unit 348, the plate pin elevator of the plate lifting unit 348 can move the first plate pin 348-11 and the second plate pin 348-21 to a preset height, thereby being able to adjust the balance of both sides of the cabinet drawer D. On the other hand, when the cabinet drawer D is pushed into the tester T, the actions of the first slide feeder 345-1 and the second slide feeder 345-2 as described above are performed in reverse order.

[0361] Insert the hand

[0362] If you refer to it again Figure 52 to Figure 56 The insertion hand 350 according to one embodiment of the present invention can load or unload electronic components ED between the cabinet drawer D of the tester T and the shuttle 100. The insertion hand 350 may include an insertion unit 351, a hand horizontal mover 352, a hand vertical mover 353, and a hand detector 354.

[0363] The insertion unit 351 may be moved in the horizontal direction by the hand horizontal mover 352 and in the vertical direction by the hand vertical mover 353. The insertion unit 351 may include an insertion body 351-1, an insertion holder 351-2, an insertion horizontal mover 351-3, and an insertion vertical mover 351-4.

[0364] The insertion body 351-1 may be disposed in a manner adjacent to the tester T. When the cabinet drawer D is pulled out of the tester T and supported by the plate feeder 340, the insertion body 351-1 may be moved in the front-to-rear direction (Y direction) or the left-to-right direction (X direction) so as to be as close as possible to the point where the cabinet drawer D of the tester T is located. The insertion body 351-1 may be moved in the up-down direction (Z direction) along the handle vertical guide rail, or may be guided in the front-to-rear direction (Y direction) along the first handle horizontal guide rail, or may be moved in the left-to-right direction (X direction) along the second handle horizontal guide rail.

[0365] The insertion clamp 351-2 can grip or release the electronic component ED. The insertion clamp 351-2 can be set to be a plurality of insertion clamps 351-2 that are spaced apart in the left and right directions (X direction) on the insertion body 351-1. As an example, the insertion clamp 351-2 may include a first insertion clamp 351-21, a second insertion clamp 351-22, an insertion clamp support sheet 351-23, an insertion lifting actuator 351-24, and an insertion lifting guide rail 351-25.

[0366] The first insertion gripper 351-21 can insert one electronic component ED into one slit formed on the cabinet drawer D. In other words, when the insertion hand 350 moves close to the cabinet drawer D, one electronic component ED loaded on the shuttle 100 can be inserted into one slit formed on the cabinet drawer D. The first insertion gripper 351-21 can be spaced apart in a manner adjacent to each other in the left-right direction (X direction). The first insertion gripper 351-21 can be moved in the left-right direction (X direction) by the first horizontal mover.

[0367] The second insertion clamp 351-22 can be separated from the first insertion clamp 351-21 in the left-right direction (X direction). When the first insertion clamp 351-21 inserts an electronic component ED into a slit formed on the cabinet drawer D, the second insertion clamp 351-22 can simultaneously or sequentially insert another electronic component ED into another slit adjacent to the slit. In addition, in order to overcome the limitations of the insertion clamp pitch adjustment caused by differences such as the gaps between the utensils around the socket or the sockets, a portion of the first insertion clamp 351-21 or the second insertion clamp 351-22 can also be raised or lowered. For this purpose, a distance sensor is provided to identify different situations and respond accordingly. In addition, by understanding the position of the socket and the position of the electronic component through the camera, the spacing of the first insertion clamp 351-21 or the second insertion clamp 351-22 can be adjusted, or the spacing adjustment limitation of the insertion clamp can be overcome by lifting and horizontally moving the first insertion clamp 351-21 or the second insertion clamp 351-22 as a whole. The second insertion clamp 351-22 can be moved multiple times in the left and right direction (X direction) by the first insertion horizontal mover 351-31 and the second insertion horizontal mover 351-32. As an example, when the first insertion clamp 351-21 is moved in the left-right direction (X direction) by the first insertion horizontal mover 351-31, the second insertion clamp 351-22 can be moved by the first insertion horizontal mover 351-31 by the distance that the first insertion clamp 351-21 is moved in the left-right direction (X direction), and further moved by the second insertion horizontal mover 351-32 by a distance shorter than the moving distance of the first insertion clamp 351-21 in the left-right direction (X direction). Each of the first insertion clamp 351-21 and the second insertion clamp 351-22 may include an end side insertion clamp component 351-201, an other end side insertion clamp component 351-202, an insertion clamp protrusion 351-203, and a push block 351-204.

[0368] One end side insert clamp component 351-201 and the other end side insert clamp component 351-202 can selectively grasp an electronic component ED. One end side insert clamp component 351-201 and the other end side insert clamp component 351-202 can be fixed on the rotating belt in a manner of moving in opposite directions to each other. When the rotating belt rotates, one end side insert clamp component 351-201 and the other end side insert clamp component 351-202 can move in opposite directions to each other through the rotating belt. As an example, one end side insert clamp component 351-201 and the other end side insert clamp component 351-202 can be configured to be able to move in a direction close to or away from the insertion body 351-1.

[0369] The insertion clamp protrusion 351-203 can be formed by protruding from the end of the insertion clamp component 351-201 on one end side and the insertion clamp component 351-202 on the other end side. The insertion clamp protrusion 351-203 can be set to a hook shape that can engage with the card slot of the electronic component ED. When the end of the insertion clamp component 351-201 on one end side and the end of the insertion clamp component 351-202 on the other end side move in a direction approaching each other, the insertion clamp protrusion 351-203 engages with the card slot of the electronic component ED, thereby selectively grasping one electronic component ED.

[0370] The push block 351-204 can be detachably arranged on the one-end side insertion clamp component 351-201 and the other-end side insertion clamp component 351-202. When the push block 351-204 is detachably arranged on the one-end side insertion clamp component 351-201 and the other-end side insertion clamp component 351-202, the push block 351-204 is installed on the one-end side insertion clamp component 351-201 and the other-end side insertion clamp component 351-202 in a manner that the height can be adjusted. When the engagement state between the insertion clamp protrusion 351-203 and the card slot of the electronic component ED is released, the push block 351-204 can push the top of the electronic component ED through the control of the controller 500. The action of the insertion hand 350 as described above can be adjusted by the controller 500. For example, the controller 500 may move the insertion clamper 351-2 from the shuttle 100 to the slit formed on the cabinet drawer D in a state where the insertion clamper protrusion 351-203 and the card slot of the electronic component ED are engaged. When the electronic component ED is located in the slit formed on the cabinet drawer D, the controller 500 may release the engagement state between the insertion clamper protrusion 351-203 and the card slot of the electronic component ED, and when the engagement state between the insertion clamper protrusion 351-203 and the card slot of the electronic component ED is released, control the insertion clamper 351-2 to cause the push block 351-204 to push the top of the electronic component ED.

[0371] The insertion clamp support piece 351-23 may be provided as a plurality of pieces capable of independently supporting the first insertion clamp and the second insertion clamp 351-22. A plurality of insertion clamp support pieces 351-23 are provided on the insertion lifting guide rail 351-25 in a slidable manner. On each insertion clamp support piece 351-23, the first insertion clamp and the second insertion clamp 351-22 may be movably provided in a direction close to or away from each other.

[0372] The insertion lifting actuator 351-24 may be a lifting actuator for lifting the insertion clamp support piece 351-23. The insertion lifting actuator 351-24 may be provided as a plurality of drivingly connected to the first insertion clamp 351-21 and the second insertion clamp 351-22 through the insertion clamp support piece 351-23. When the insertion lifting actuator 351-24 is actuated, the first insertion clamp 351-21 and the second insertion clamp 351-22 may move in the up and down directions.

[0373] The insertion lifting guide rail 351-25 can provide a moving path for the insertion clamp support piece 351-23 to move in the up-down direction. The insertion lifting guide rail 351-25 can be arranged to be a plurality of insert clamp support pieces 351-23 arranged side by side in accordance with the number of insert clamp support pieces 351-23. The insert clamp support pieces 351-23 are arranged on a plurality of insertion lifting guide rails in a slidable manner. When the insertion lifting actuator 351-24 is actuated, the second insertion clamp and the second insertion clamp 351-22 can be guided in the up-down direction by the insertion lifting guide rail 351-25.

[0374] The insertion horizontal mover 351-3 may include a first insertion horizontal mover 351-31 and a second insertion horizontal mover 351-32. The first insertion horizontal mover 351-31 may move the insertion gripper 351-2 in a horizontal direction. The first insertion horizontal mover 351-31 may include a first insertion horizontal guide rail 351-311 and a first insertion transfer motor 351-312.

[0375] The second insertion horizontal mover 351-32 may provide a horizontal moving path shorter than that of the first insertion horizontal mover 351-31. Either the first insertion clamper 351-21 or the second insertion clamper 351-22 may be disposed on the second insertion horizontal mover 351-32 in a manner movable in the horizontal direction. The second insertion horizontal mover 351-32 may include a second insertion horizontal guide rail 351-321 and a second insertion transfer motor 351-322.

[0376] The insertion vertical mover 351-4 can move the insertion clamp 351-2 in the vertical direction (up and down direction). The insertion vertical mover 351-4 can move the insertion clamp 351-2 to a first gripping height or a second gripping height. The first gripping height can be a height at which the insertion clamp 351-2 can grip or release the above-mentioned electronic component ED, and the second gripping height can be a height at which the insertion clamp 351-2 is located at a position higher than the first gripping height. The insertion vertical mover 351-4 can include an insertion vertical guide rail 351-41 and an insertion drive motor 351-42.

[0377] The hand horizontal mover 352 may move the insertion unit 351 in the horizontal direction. The hand horizontal mover 352 may be disposed on the insertion body 351-1. The hand horizontal mover 352 may include a first hand horizontal mover 352-1 and a second hand horizontal mover 352-2. The first hand horizontal mover 352-1 may move the insertion clamp 351-2 in the front-rear direction (Y direction), and the second hand horizontal mover 352-2 may move the insertion clamp 351-2 in the left-right direction (X direction).

[0378] The hand vertical mover 353 can move the insertion unit 351 in the vertical direction (up and down direction) by moving the hand horizontal mover 352 in the vertical direction. The hand horizontal mover 352 may be provided on the hand vertical mover 353 in a manner that allows sliding movement in the vertical direction.

[0379] In addition, the hand vertical mover 353 can move the insertion unit 351 in the vertical direction, so that the electronic component grasped by the insertion unit 351 can be moved in the vertical direction, and the hand vertical mover 353 is configured to be able to move the hand vertical mover 353 in the horizontal direction.

[0380] The hand detector 354 may be provided on the insertion unit 351. The hand detector 354 may include a handle camera and a handle distance sensor. The handle camera may confirm the position of the insertion hand 350. When the insertion hand 350 is located on the upper side of the cabinet drawer D, the handle distance sensor may measure the relative distance to a reference point on the cabinet drawer D. The insertion distance measuring sensor may detect the four edge portions of the cabinet drawer D, thereby being able to confirm the overall inclination of the cabinet drawer D. In addition, the handle distance sensor may detect the specific position of a fan disposed around a test socket of the cabinet drawer D into which the electronic component ED is inserted.

[0381] Next, the function and effect of the insertion hand having the above-mentioned structure will be described.

[0382] In the case where the insertion hand 350 inserts the electronic component ED loaded on the shuttle 100 into the test socket of the cabinet drawer D, when the insertion gripper 351-2 of the insertion hand 350 is located at the first descending position (the position when the end of the electronic component ED enters the guide portion of the test socket of the cabinet drawer D), the insertion gripper 351-2 can release the gripping state of the electronic component ED. At this time, the electronic component ED can be (temporarily) inserted from the insertion gripper 351-2 into the test socket of the cabinet by its own weight.

[0383] When the electronic component ED is inserted into the test socket of the cabinet drawer D, the push block 351-204 of the insertion clamp 351-2 can move the electronic component ED to the second lowered position (the position when the electronic component ED is fully inserted into the test socket of the cabinet drawer D) by pushing the top of the electronic component ED.

[0384] After completing the test of the electronic component ED, when the insertion hand 350 separates the electronic component ED loaded on the shuttle 100 into the test socket of the cabinet drawer D, when the insertion clamp 351-2 of the insertion hand 350 is located at the second descending position, the insertion clamp protrusion 351-203 of the insertion clamp 351-2 can engage with the two side ends of the electronic component ED, and in the state where the clamp protrusion and the two side ends of the electronic component ED are engaged, the insertion clamp 351-2 can separate the electronic component ED from the test socket of the cabinet drawer D by moving upward.

[0385] Buffer unit

[0386] When referring to Figure 60 to Figure 63 When the electronic components ED are tested, the buffer unit 480 may receive the customer tray. The buffer unit 480 may include a buffer frame 481, a first buffer lock 482, and a second buffer lock 483.

[0387] The buffer frame 481 may be configured to be in the shape of a loading tray capable of accommodating a customer tray. A plurality of customer trays may be disposed on the buffer frame 481 in a detachable manner. The customer tray mounted on the buffer frame 481 may receive the electronic component ED from the unloading hand. The buffer frame 481 may include a buffer space 481-1, a buffer partition 481-2, and a partition partitioning piece 481-3. The buffer space 481-1 may provide a plurality of spaces capable of accommodating a customer tray. The buffer space 481-1 may be divided by a buffer partition 481-2. The buffer partition 481-2 is disposed between a plurality of buffer spaces 481-1. The buffer partition 481-2 may be formed by extending in the length direction of the buffer frame 481. The buffer partition 481-2 may be disposed in the center portion of the buffer frame 481. A plurality of partition partitioning pieces 481-3 are disposed separately on the buffer partition 481-2. A plurality of partition partitioning pieces 481-3 may support one side edge portion of a customer tray.

[0388] When the customer tray is received in the buffer frame 481, the first buffer lock 482 may support a side wall of the edge of the customer tray received in the buffer frame 481. The first buffer lock 482 may be fixedly disposed at a side edge of the buffer frame 481. The first buffer lock 482 may include a first buffer shaft 482-1, a first buffer dividing piece 482-2, and a first buffer roller 482-3.

[0391] The first buffer dividing piece 482-2 can rotate in conjunction with the rotation of the first buffer shaft 482-1. When the first buffer dividing piece 482-2 is rotated by the first buffer shaft 482-1, it can selectively limit the side edge of the customer tray received in the buffer frame 481. As an example, when the first buffer dividing piece 482-2 rotates along the inner side direction of the buffer frame 481 by the rotation of the first buffer shaft 482-1 in one direction, the first buffer dividing piece 482-2 can limit the side edge of the customer tray received in the buffer frame 481. In addition, when the first buffer dividing piece 482-2 rotates along the outer side direction of the buffer frame 481 by the rotation of the first buffer shaft 482-1 in one direction, the first buffer dividing piece 482-2 can release the restriction on the side edge of the customer tray received in the buffer frame 481.

[0392] The first buffer roller 482-3 can support the side wall of the customer pallet. The first buffer roller 482-3 can be set to be multiple and arranged on the first buffer partition sheet 482-2 so as to be able to closely fit the side wall of the customer pallet. When the customer pallet is disassembled and assembled in the buffer space 481-1, the first buffer roller 482-3 supports the side wall of the customer pallet through the roller, so that the customer pallet can be smoothly disassembled and assembled on the buffer frame 481.

[0393] When the customer tray is received in the buffer frame 481, the second buffer lock 483 may support the other side wall of the edge of the customer tray received in the buffer frame 481. The second buffer lock 483 may be fixedly disposed at the other side edge of the buffer frame 481. The second buffer lock 483 may include a second buffer shaft 483-1, a second buffer dividing piece 483-2, and a second buffer roller 483-3.

[0394] The second buffer shaft 483-1 is rotatably disposed at the other side edge of the buffer frame 481. A plurality of second buffer partitions 483-2 may be spaced apart and disposed on the second buffer shaft 483-1 in the length direction. When the second buffer shaft 483-1 rotates in one direction or the other direction, the plurality of second buffer partitions 483-2 may rotate in the outer direction or the outer direction of the buffer frame 481.

[0395] The second buffer partition 483-2 can support the other side edge of the customer tray. The second buffer partition 483-2 can be configured to be arranged at a position corresponding to the plurality of partition partitions 481-3. A buffer space 481-1 is provided between the plurality of second buffer partitions 483-2 and the plurality of partition partitions 481-3. Among the plurality of second buffer partitions 483-2, the second buffer partitions 483-2 arranged at both ends of the second buffer shaft 483-1 can be configured as " " shape, the second buffer dividing piece 483-2 arranged in the middle part of the second buffer shaft 483-1 can be arranged in a "T" shape.

[0396] The second buffer dividing piece 483-2 can rotate in conjunction with the rotation of the second buffer shaft 483-1. When the second buffer dividing piece 483-2 is rotated by the second buffer shaft 483-1, it can selectively limit the other side edge of the customer tray received in the buffer frame 481. As an example, when the second buffer dividing piece 483-2 can be rotated in the inner direction of the buffer frame 481 by rotating the second buffer shaft 483-1 in one direction, the second buffer dividing piece 483-2 can limit the other side edge of the customer tray received in the buffer frame 481. In addition, when the second buffer dividing piece 483-2 is rotated in the outer direction of the buffer frame 481 by rotating the second buffer shaft 483-1 in the other direction, the second buffer dividing piece 483-2 can release the restriction on the other side edge of the customer tray received in the buffer frame 481.

[0397] The second buffer roller 483-3 can support the side wall of the customer pallet. The second buffer roller 483-3 can be set to be a plurality of second buffer rollers 483-3 arranged on the second buffer partition sheet 483-2 so as to be able to closely fit the side wall of the customer pallet. When the customer pallet is disassembled and assembled in the buffer space 481-1, the second buffer roller 483-3 supports the side wall of the customer pallet through the roller, so that the customer pallet can be smoothly disassembled and assembled on the buffer frame 481.
