The sorter HR according to this embodiment includes a stacker part SP, a connection part CP, and a transfer part TP.

The stacker section SP accommodates the customer pallet CT on which the electronic component ED is mounted. This stacker section SP is used to receive from the outside the customer pallet CT on which the electronic component ED that needs to be tested is mounted, or for transferring the customer pallet CT on which the electronic component ED that has been tested is mounted to the outside. In addition, the stacker part SP is also used for storing customer pallets CT that are carried in from the outside or to be carried out to the outside.

Recover to the stacker section SP.

Each part (SP, CP, TP) will be classified according to the catalog and explained in more detail below. ＜Instructions for the stacker part＞

As shown in the schematic extraction diagram of FIG. 4 , the stacker section SP has five stackers 100 for entry and exit, five stackers 200 for storage, five stackers 300 , a conveyor 400 and two buffers. Use stacker 500. In the following description of the stacker part SP, "outside" and "inside" are defined based on the arrangement relationship between the stackers of symbols 100, 200, and 300 and the conveyor 400. That is, the side from the conveyor 400 facing the stackers 100, 200, and 300 (the left side in the plan view of FIG. 2) is defined as the "outside", and the side facing the stackers 100, 200, and 300 One side of the conveyor 400 is defined as the "inside" (the right side in the plan view of Figure 2). 1. Instructions for stackers for entry and exit

Each of the access stackers 100 has the same structure, and five of them are arranged side by side in the horizontal direction (the front-rear direction based on the picture of FIG. 2 ).

The loading and unloading stacker 100 is used to receive from the outside customer pallets CT in bundles containing electronic components ED to be tested, or to receive customer pallets CT in bundles containing electronic components ED that have been tested. transmitted to the outside. That is, each of the five loading and unloading stackers 100 can be used to carry the customer pallet CT into the sorting machine HR, or can be used to carry the customer pallet CT out of the sorting machine HR according to the control. Therefore, as shown in the extracted view of FIG. 5 and the exploded perspective view of FIG. 6 , the access stacker 100 includes a storage device 110 , a first switch 120 , a moving plate 130 , a base plate 140 , a first forward and backward mover 150 , Rotator 160 and first mover 170 .

The container 110 can store customer pallets CT in bundle units. That is, a plurality of customer pallets CT loaded into or unloaded from the sorting machine HR by an operator or an automated system are in a bundled state. In addition, depending on the situation, the uppermost customer tray CT can be covered with a separate cover tray. Therefore, the container 110 needs to ensure the first storage space S1 so as to be able to accommodate the customer trays CT received from the outside or transferred to the outside in bundle units. To this end, the container 110 includes first supports 111o, 111i and a rotating plate 112.

The first supports 111o and 111i support the side surfaces of the four corners of the customer pallet CT to prevent the customer pallet CT stored in the first storage space S1 from being detached. Therefore, the first support members 111o and 111i form a first storage space S1 capable of accommodating the customer tray CT inside the edge connecting them.

The rotating plate 112 is rotatably arranged, and a conveyor belt 171 including a first shutter 120 and a first mover 170 to be described later is provided on the rotating plate 112 . Obviously, the customer pallet CT is placed on the conveyor belt 171. In addition, the first supporting members 111o and 111i are fixedly provided on the rotating plate 112.

The first shutter 120 rotates the first support member 111i located in the inward direction of the sorting machine HR forward or reversely, so that the first support member 111i can support the corners of the four sides of the customer pallet CT located in the inward direction. side, or as shown in the reference drawing of Figure 7, release the support for that side. At this time, if the first support member 111i is in a state where the support of the four corners of the customer tray CT located in the inward direction is released, the first storage space S1 is opened in the inward direction, so that the customer tray CT can move in the inward direction. condition.

The movable plate 130 is equipped to be movable in the inner and outer directions, and is provided with a rotator 160 which will be described later.

The base plate 140 is fixed, and the rails of the movable plate 130 that can move in the inner and outer directions are coupled to the rails R located on the base plate. Furthermore, the base plate 140 is provided with a second cylinder 153 of the first forward and backward mover 150 and an operation motor 172 of the first mover 170 which will be described later.

As shown with reference to the conceptual diagrams of (a) and (b) of FIG. 8 , after the first forward and backward mover 150 moves the container 110 forward and outward of the sorting machine HR to reach the state of (a) of FIG. 8 , The container 110 is moved backward again and restored to the original position as shown in (b) of FIG. 8 . According to this embodiment, the storage stacker 200 is located above the access stacker 100 . Therefore, it is difficult for an operator or the automation system to store the customer tray CT in the storage container 110 or to collect the customer tray CT stored in the storage container 110 . In order to solve this problem, in this embodiment, the first forward and backward mover 150 moves the container 110 forward and outward of the sorting machine HR, so that the operator or the automation system can store the customer pallet CT in the first container. Space S1 or the state of recovering customer pallets CT from the first storage space S1. And when the customer tray CT is stored in the first storage space S1 or the customer tray CT is recovered from the first storage space S1, the first forward and backward mover 150 moves the container 110 backward toward the inside of the sorting machine HR, thereby moving the container 110 restored to its original position. Therefore, as shown in the extracted view of FIG. 9 , the first forward and backward mover 150 is composed of a first air cylinder 151 , a support plate 152 , and a second air cylinder 153 .

Since the piston rod of the first cylinder 151 is coupled to the moving plate 130, when the first cylinder 151 is operated, the moving plate 130 moves once in the inner and outer directions.

The support plate 152 is orbitally coupled to the base plate 140 in a manner that can move inward and outward directions. The first cylinder 151 is fixedly provided on the support plate 152 .

The second cylinder 153 is fixedly installed on the base plate 140 , and its piston rod is combined with the support plate 152 . Therefore, when the second air cylinder 153 is operated, the support plate 152 moves in the inward and outward directions, and the moving plate 130 moves twice.

As mentioned above, the two air cylinders 151 and 153 are used to enable the movable plate 130 to move repeatedly, so that the moving distance of the container 110 can be fully ensured.

The rotator 160 rotates the rotating plate 112 forward or reversely at an angle of 90 degrees. Therefore, taking into account the electrical connection direction between the electronic component ED and the tester TESTER, even if the direction of the customer pallet CT supplied through the conventional automation system is supplied with a difference equivalent to 90 degrees, it can be achieved by the rotation of the rotator 160 Run to correct the direction of customer pallet CT. For example, in the case of a conventionally installed automated system that supplies customer pallets CT in the correct orientation, there is no need to operate the rotator 160 . However, if a conventionally installed automation system supplies customer pallets CT in a direction that is 90 degrees different from the normal direction, as shown in the conceptual diagram with reference to FIG. 10 , the rotator 160 is operated to cause the container 110 to After the forward rotation of 90 degrees, if the customer pallet CT is stored in the first storage space S1, it will be rotated in the reverse direction of 90 degrees again, so that the direction of the customer pallet CT can be corrected. Therefore, regardless of the type of electronic component ED, the previously installed automation system can be directly used to smoothly carry the customer pallet CT into the sorter HR, or smoothly move the customer pallet CT from the sorter HR. Of course, in order to minimize the installation space, it is preferable to implement and control the rotator 160 so as to rotate only when the storage container 110 advances to the outside of the sorting machine HR.

For reference, in this embodiment, the rotator 160 is composed of the cylinder 161, the rack 162, the pinion 163, etc., but depending on the embodiment, it can be appropriately applied in any form as long as it is a structure that can rotate the rotary plate 112. .

The first mover 170 is configured to move the customer trays CT stored in the storage unit 110 in the inward direction to exit the customer trays CT from the first storage space S1, or to move the customer trays conveyed from the inside. CT moves in the outer direction and the customer tray CT enters the first storage space S1. In this embodiment, as shown in the extracted view of FIG. 11 , the first mover 170 is implemented as having the conveyor belt 171 . However, as long as it is a structure that can move the customer pallets CT in bundle units in the inward and outward directions, it is not necessary. Limited to conveyor belt structures. This first mover 170 has an operation motor 172 for operating the conveyor belt 171, a rotation shaft 173, and a power transmitter 174.

The operating motor 172 provides power for the circular movement of the conveyor belt 171 .

The rotating shaft 173 is rotated by the power of the operating motor 172 .

The power transmitter 174 transmits the rotational force of the rotation shaft 173 to the conveyor belt 171 .

For reference, as shown in the conceptual diagram of FIG. 12 , the rotating shaft 173 is divided into an upper shaft 173T, a lower shaft 173B, and a moving shaft 173M. The moving shaft 173M coupled to the lower shaft 173B is lifted and lowered by the lifting member 175 , so that the upper shaft 173T and the moving shaft 173M can be coupled or decoupled to each other and separated. Therefore, when the moving plate 130 is in a state of moving forward and backward or advancing outward, as shown in (a) of FIG. 12 , the moving shaft 173M is lowered by the lifting member 175 so that the upper shaft 173T and the moving shaft 173M are at a distance open state, thereby preventing interference between the rotating shaft 173 and the moving plate 130 . Of course, in the state where the moving plate 130 is restored to the original position, especially when the first mover 170 is operating and the customer trays CT in bundles are withdrawn from the first storage space S1, as shown in (b) of FIG. 12 As shown, the moving shaft 173M needs to be raised by the lifting member 175 so that the moving shaft 173M is coupled to the upper shaft 173T, so that the power of the operating motor 172 is transmitted to the conveyor belt 171 through the rotating shaft 173 and the power transmitter 174 . For reference, the lower shaft 173B is connected to the operation motor 172, and the upper shaft 173T is gear-engaged with the power transmitter 174 side.

Next, the operation of the entry and exit stacker 100 will be described.

First, when the customer pallet CT is supplied in bundle units by an operator or an automated system, the first forward and backward mover 150 is operated to move the container 110 forward toward the outside of the sorter HR. In this state, the customer pallets CT in bundle units are loaded in the first storage space S1 while descending from above. At this time, if the direction of the customer pallet CT needs to be corrected, before the customer pallet CT is lowered, the rotator 160 is operated in advance to make the container 110 rotate forward at an angle of 90 degrees. When the CT is stored in the first storage space S1, the rotator 160 rotates in the reverse direction, causing the container 110 to rotate in the reverse direction at an angle of -90 degrees.

When the customer trays CT in bundles are stored in the first storage space S1, the first forward and backward mover 150 is operated to move the container 110 backward toward the inside of the sorting machine HR, thereby returning the container 110 to its original position. s position.

In addition, when the customer trays CT in bundles located in the first storage space S1 are to be moved inward, the first shutter 120 is operated to forwardly rotate the first support 111i located inside, thereby moving inward. The first storage space S1 is opened in the direction. Furthermore, in this state, the first mover 170 operates to move the customer pallets CT in bundle units inwardly, thereby withdrawing the customer pallets CT in bundle units from the first storage space S1 inwardly. 2. Instructions for storage stackers

The five storage stackers 200 all have the same structure and are respectively located on the lower side of the entry/exit stacker 100. They are used to store customer pallets CT in bundles received from the outside through the entry/exit stacker 100. Alternatively, customer pallets CT in bundles that need to be conveyed to the outside through the entry/exit stacker 100 are stored before being conveyed to the entry/exit stacker 100 . Therefore, as shown in the extracted view of FIG. 13 , the storage stacker 200 has four second supports 211 o and 211 i, a second switch 220 and a second mover 270 .

The four support members 211o and 211i support the corners of the four sides of the customer pallet CT and form a second storage space S2 that can accommodate the customer pallet CT.

The second shutter 220 and the second mover 270 are substantially the same as the first shutter 120 and the first mover 170 respectively, and therefore their description is omitted. 3. Instructions for stacker crane 300

The five stackers 300 all have the same structure and are located on the lower side of the access stacker 100 . This stacker 300 has substantially the same structure as the entry/exit stacker 100 or the storage stacker 200, and therefore its detailed description is omitted.

The stacker 300 can be used for various purposes as illustrated below.

For example, when the cover pallet covers the uppermost customer pallet CT among the customer pallets CT in the bundle unit, any one of the stackers 300 may be used to store the cover pallet.

For example, the stacker 300 can be used to store customer pallets CT containing a small number of electronic components ED that are judged to be defective products.

For example, the stacker 300 can be used to classify good electronic components ED according to test levels and temporarily store them.

For example, when it is difficult to move the customer pallet CT using the current access stacker 100 or the storage stacker 200 , the stacker 300 can be used for temporary standby.

That is, the stacker 300 can function as a multi-purpose stacker that can be applied to various purposes according to control.

Furthermore, it is considered preferable that the storage capacity of the customer pallet CT of this type of stacker 300 is smaller than that of the entry/exit stacker 100 or the storage stacker 200 in order to prevent the sizer HR from becoming larger. 4. Instructions for conveyors

The conveyor 400 is equipped to be responsible for the movement of the customer pallets CT in the stacker section SP in order to move the customer pallets in bundles at once between the entry and exit stacker 100 and the storage stacker 200 . CT, or supplying customer pallets CT in single sheets (referring to one sheet) located in the access stacker 100 or the storage stacker 200 to the transfer device TA. Of course, the conveyor 400 also moves the customer pallets CT in units of sheets transferred by the transfer device TA to the stackers 100, 200, and 300. To this end, as shown in the extracted view of FIG. 14 , the conveyor 400 includes a first gripper 410 , a second gripper 420 , a lifter 430 and a horizontal mover 440 .

The first clamper 410 is provided on the upper side of the second clamper 420 and can clamp or release the clamping of customer pallets CT in bundles at one time. For this reason, as shown in the extracted view of FIG. 15 , the first holder 410 includes third supports 411 o and 411 i, a third shutter 412 , and a third mover 413 .

The third support members 411o and 411i support the side surfaces of the four corners of the customer pallet CT in bundle units, and form a storage space S3 in which the customer pallet CT in bundle units can be stored. Such third support members 411o and 411i are jointly provided on the upper surface of the coupling plate JP.

The third shutter 412 rotates the third support 411o located in the outer direction, so that the customer trays CT in bundle units that move horizontally inward or outward can enter or exit the storage space S3. That is, the storage space S3 is opened or closed to the outside according to the rotation state of the third support 411o by the operation of the third shutter 412.

The third mover 413 is equipped for horizontally moving the customer pallets CT in bundles entering or exiting the storage space S3 , and in the same manner as the first mover 170 in this embodiment. This is implemented to include a conveyor belt 413a.

The second holder 420 is provided on the lower side of the first holder 410 . That is, the first holder 410 and the second holder 420 are aligned and arranged in the vertical direction, and are coupled to each other with the coupling plate JP interposed therebetween. That is, the first clamper 410 is also provided on the coupling plate JP, and the second clamper 420 is also provided on the coupling plate JP.

The second gripper 420 can grip or release the customer pallet CT in single sheets. To this end, as shown in the extracted view of FIG. 16 , the exploded perspective view of FIG. 17 , and the partial extracted view of FIG. 18 , the second clamper 420 includes a first forward and backward moving plate 421 , a second forward and backward moving plate 422 , a pair of Clamping rod 423, a pair of distance adjustment sources 424, and a second forward and backward mover 425.

The first forward and backward movement plate 421 is coupled to the coupling plate JP rail so as to be capable of forward and backward movement in the inner and outer directions.

The second forward and backward moving plate 422 is orbitally coupled to the first forward and backward moving plate 421 so as to be able to move forward and backward in the inner and outer directions.

The pair of clamping rods 423 are provided on the second forward and backward movement plate 422 so as to face each other in the front-rear direction in the figure, and have clamping hooks GH for clamping the customer pallets CT in units of sheets.

A pair of spacing adjustment sources 424 provides power for narrowing or widening the spacing between a pair of clamping rods 423 . Therefore, depending on the operating state of the pair of distance adjustment sources 424, the pair of clamping rods 423 is in a state of clamping the customer pallet CT or in a state of releasing the clamping.

The second forward and backward mover 425 provides a forward and backward moving force that allows the first forward and backward moving plate 421 and the second forward and backward moving plate 422 to move forward and backward in the inner and outer directions. This second forward and backward mover 425 has a dual conveyor belt structure, and includes a drive motor 425a, a first conveyor belt 425b, and a second conveyor belt 425c.

The drive motor 425a provides power to circulate the first conveyor belt 425b and the second conveyor belt 425c.

The first conveyor belt 425b is provided on the coupling plate JP. Furthermore, the first forward and backward moving plate 421 is coupled to the first conveyor belt 425b, so that the first forward and backward moving plate 421 linearly moves in the inner and outer directions by the cyclic rotation of the first conveyor belt 425b.

The second conveyor belt 425c is provided on the first forward and backward moving plate 421. Furthermore, the second forward and backward movement plate 422 is coupled to one side point P1 of the second conveyor belt 425c, and is coupled to the coupling plate JP with a coupling member JE interposed therebetween at the other side point P2. Here, in order to eliminate interference between the coupling member JE and the first forward and backward movable plate 421, the first forward and backward movable plate 421 is formed with a long through hole TH in the inner and outer directions through which the coupling member JE can pass.

For reference, it can be preferably considered that the second clamper 420 is equipped with a pressure plate PP that is elastically supported by an elastic member E such as a spring to achieve elasticity on the upper surface of the clamped customer pallet CT. Pressurized for stable clamping of customer pallets CT. Of course, the elastic member E is provided between the pressure plate PP and the second forward and backward movement plate 422 . In addition, in this embodiment, the first forward and backward moving plate 421 and the second forward and backward moving plate 422 are provided to fully ensure the moving distance of the clamping rod 423, and the double conveyor belts 425b and 425c are applied, but it may be sufficient. It is considered that the second forward and backward moving plate is equipped with only one forward and backward moving plate provided with the clamping rod 423, and the second forward and backward moving plate 425 moves only one forward and backward moving plate forward and backward in the inner and outer directions.

The lifter 430 moves the coupled first holder 410 and the second holder 420 together in the vertical direction.

The horizontal mover 440 moves the lifter 430 in the horizontal direction, and finally moves the first clamper 410 and the second clamper 420 combined with the lifter 430 in the horizontal direction together. Here, the horizontal direction refers to the horizontal line direction perpendicular to the direction in which the customer pallet CT in a bundle unit moves inward or outward (in the diagram of FIG. 2 , the front-rear direction).

Next, the operation of the second clamper 420 will be described, taking an example of clamping customer pallets CT in single sheets from the storage stacker 200 .

The lifter 430 and the horizontal mover 440 are operated so that the second clamper 420 is located at a position corresponding to the storage stacker 200 that requires operation. Then, the second forward and backward movement device 425 is operated to cause the second forward and backward movement plate 422 to enter the second storage space S2 of the storage stacker 200 . As a result, the pair of clamping rods 423 will be located on the front and rear sides of the uppermost customer pallet CT, and then the distance adjustment source 424 is operated to reduce the distance between the pair of clamping rods 423, thereby clamping the customer pallet CT. At this time, the clamping hook GH enters the gap between the upper customer tray CT and the lower customer tray CT. Furthermore, the lifter 430 slightly lifts the second clamper 420 to completely separate the upper customer tray CT and the lower customer tray CT clamped by the second clamper 420 so that they do not interfere with each other. , the second forward and backward moving device 425 is operated in the reverse direction, so that the second forward and backward moving plate 420 is withdrawn from the second storage space S2. Through the above operation, the conveyor 400 can take out the customer pallets CT in single sheets from the storage stacker 200 . Of course, by the reverse operation, the conveyor 400 can also move the customer pallets CT in units of sheets to the storage stacker 200 .

That is, as described above, the conveyor 400 of this embodiment can use the first clamper 410 to move the customer trays CT in bundles at once, or can use the second clamper 420 to move only the customer trays CT in single sheets. A customer pallet CT moves. Therefore, the operation of transporting customer pallets CT in bundle units or the operation of transporting customer pallets CT in single-unit units can be prevented from being disturbed, and the sorting machine HR can be prevented from becoming excessively large. 5. Instructions for buffer stackers

Two buffer stackers 500 are installed in order to make the logistics process of customer pallets CT proceed quickly and smoothly, and are spaced apart from the inside of the entry and exit stacker 100, the storage stacker 200, and the stacker 300. In the embodiment, it is provided below the second holder 420 .

As shown in the extracted view of FIG. 19 , the buffer stacker 500 is equipped with four fourth supports 511 , a support plate 512 , a lifter 513 , a setting plate 514 and four guides 515 .

The fourth support member 511 forms a fourth storage space S4 in which the lid tray can be accommodated, and supports the four corner side surfaces of the lid tray accommodated in the fourth storage space S4.

The support tray 512 supports the cover tray accommodated in the fourth storage space S4.

The lifter 513 raises and lowers the support plate 512, as shown in the extracted view of FIG. 20, and includes a lift motor 513a, a transmission belt 513b, a lift shaft 513c, and a rotating component 513d.

The lift motor 513a generates power for raising and lowering the lift shaft 513c.

The transmission belt 513b transmits the lifting rotation force generated by the lifting motor 513a to the rotating component 513d.

The lifting shaft 513c is in the shape of a long rod along the up and down direction, and is ultimately coupled to the installation plate 514 side so as to be able to lift and lower.

The rotating member 513d is rotatably coupled to the setting plate 514. Furthermore, the lifting shaft 513c and the rotating member 513d are coupled with a bolt and nut. When the rotating member 513d is rotated by the operation of the lifting motor 513a, the lifting shaft 513c whose rotation is prohibited is raised and lowered.

The installation plate 514 is provided to install the support 511, the lifting motor 513a, the lifting shaft 513c, and the rotating member 513d.

The guide 515 guides the lifting and lowering movements of the supporting plate 512 and the lifting shaft 513c coupled to the supporting disk 512, and prohibits the rotation of the supporting disk 512 and the lifting shaft 513c.

For reference, in this embodiment, it is expected that the buffer stacker 500 is loaded with cover pallets, but depending on the embodiment, it is entirely possible to use it exclusively for temporarily loading customer pallets CT.

In addition, in this embodiment, a lift motor 513a is provided for lifting the support plate 512, but depending on the implementation, a lift cylinder may be used instead. However, if the cover trays are stacked on the support plate 512, the lifting height of the support plate 512 needs to be adjusted. Therefore, a lift motor 513a with adjustable lift height may be more appropriately considered than a lift cylinder.

Next, the purpose of the buffer stacker 500 will be described.

If the customer pallets CT in bundle units located in the access stacker 100 or the storage stacker 200 are to be moved to the connection portion CP in single units, the uppermost cover tray needs to be removed first. However, if the removal procedure takes a long time, the logistics of moving the customer's pallet CT will be correspondingly delayed. Therefore, the cover pallet is first moved to the buffer stacker 500 using the conveyor 400, and then the customer pallet CT is moved to the transfer part TP. Of course, the lid tray located in the buffering stacker 500 may be transferred to the storage stacker 300 while the conveyor 400 is at rest.

Furthermore, it may be realized that the customer pallet CT transferred from the connecting part CP by the transfer part TP may also pass through the buffer stacker 500 on the logistics flow.

Preferably, the buffer stacker 500 as described above is disposed on the leftmost side of the storage stacker 200 , the entry/exit stacker 100 , and the stacker 300 on the right (inside) side of the first to third floors of the storage stacker 200 . ) part of the area and is provided in the lower area on the movement path of the second clamper 420 . The reason for this is to install the buffer stacker 500 at the nearest position when quickly temporarily storing the lid pallet and the pushed customer pallet CT. ＜Instructions for connection parts＞

As shown in the conceptual plan view of FIG. 21 and the extracted view of the main part I in FIG. 22 , the connection part CP includes a rest 610 , a moving hand 620 , an opener 630 , a converter 640 , a reciprocating mover 650 and a test hand 660 .

The shelf 610 is used to hold the electronic component ED. Referring to parts (a) and (b) of the extracted view of FIG. 23 , the shelf 610 includes a pair of fixing parts 611 , a driving source 612 and a pair of transmission members 613 .

The pair of fixing members 611 can fix or release the electronic component ED by increasing or decreasing the distance between them in the left-right direction. That is, the fixing members 611 move linearly in the left-right direction under the guidance of the guide rail GR. If the distance between the fixing members 611 is enlarged, the electronic component ED or the adapter AD in which the electronic component ED is mounted is in a position where it can be placed on the shelf 610 or can be removed from the shelf 610 . If the distance between the fixing members 611 is reduced in the state where the shelf 610 is detached, the electronic component ED is in a state of being fixedly mounted on the shelf 610 .

The driving source 612 supplies driving force for adjusting the distance between the pair of fixed members 611, and is equipped with a cylinder in this embodiment.

The transmission member 613 transmits the driving force applied by the driving source 612 to the pair of fixed parts 611 . In this embodiment, a structure is adopted in which the forward and backward force of the drive source 612 as the cylinder is converted into the left and right movement force of the fixed member 611 while the transmission member 613 rotates, but various modifications are possible depending on the implementation.

The moving hand 620 moves the customer pallet CT transferred from the stacker part SP through the transfer part TP and places the electronic part ED that needs to be tested on the shelf 610, or places the tested electronic part ED on the shelf 610 The electronic component ED moves to the customer pallet CT. This mobile hand 620 clamps the horizontal electronic component ED by vacuum suction. At this time, by equipping a plurality of adsorption members, it can be selectively adsorbed by more than one adsorption member, so that various sizes can be adsorbed and clamped. All electronic components ED (refer to Korean Application No. 10-2020-0019380).

The opener 630 is used when an adapter AD as shown in FIG. 24 is used to place the electronic component ED on the shelf 610 . Here, the adapter AD is a carrier for handling relatively small electronic components ED having a size that is difficult to place directly on the shelf 610 (see Korean Application No. 10-2021-0017446). That is, the opener 630 pushes the operating part OE of the adapter AD located in the first working area W1 to open the adapter AD, thereby allowing the moving hand 620 to load or unload the electronic component ED in the adapter AD. This kind of opener 630 can be composed of a pushing member 631 for pushing the operating part OE, which is used to open the adapter AD, and an advancing and retreating source 632 for The pushing member 631 is moved forward and backward.

The converter 640 rotates the shelf 610 to finally convert the posture of the electronic component ED placed on the shelf 610 . That is, the posture of the electronic component ED can be converted from a lying position to an upright position, or from an upright position to a lying position, by the converter 640 . The electronic component ED whose posture is changed from the horizontal position to the vertical position by such a converter 640 is in a state in which the portion on the side of the contact terminal T can be appropriately inserted into the test slot S. The electronic component whose posture is changed from the vertical position to the horizontal position is The ED is in a state that can be appropriately sucked and clamped by moving the hand 620 . Of course, in the case where the electronic component ED is electrically connected to the tester TESTER in a horizontal state (for example, in the case where the test slot is formed long in the horizontal direction), the converter 640 may not perform its role, or it may The structure of the converter 640 may be omitted.

The reciprocator 650 moves the rest 610 between the first working area W1 where the moving hand 620 works and the second working area W2 where the testing hand 660 works. Since the shelving device 610 moves back and forth between the first working area W1 and the second working area W2 via the reciprocating mover 650 , the first working area W1 and the second working area W2 can be separated to eliminate the moving hand 620 and the testing hand 660 interference between.

The test hand 660 clamps the electronic component ED placed on the shelf 610 in the second working area W2, moves the electronic component ED, and inserts the portion of the electronic component ED on the contact terminal T side into the test slot S. If the electronic component ED is After the test is completed, the electronic component ED is taken out from the test slot S, and the electronic component ED that has completed the test is placed in the shelf 610 again. Of course, in the case where the adapter AD is applied, the test hand 660 moves the adapter AD holding the electronic component ED. To this end, as shown in the extracted view of FIG. 25 , the test hand 660 includes a clamping member 661 , horizontal moving members 662 a , 662 b , a vertical moving member 663 , an opening member 664 , and a connecting member 665 .

The clamping member 661 is provided for clamping the electronic component ED or the adapter AD or releasing the clamping. For this purpose, as shown in the extracted view with reference to FIG. 26 , the clamping member 661 has a pair of clamping parts 661a-1, 661a-. 2. The distance between the clamping members 661a-1 and 661a-2 is expanded or reduced by the driving force of the driving source 661b, so that the electronic component ED or the adapter AD can be clamped or released.

The horizontal moving members 662a and 662b move the clamping member 661 in the horizontal left-right direction and the front-rear direction, thereby moving the electronic component ED toward the currently empty test slot S side among the plurality of test slots S.

The vertical moving member 663 moves the clamping member 661 in the vertical direction, so that the clamping member 661 can clamp the electronic component ED or the adapter AD in the clamping position, or can raise the clamped electronic component ED or the adapter AD to the test required height and can also perform the opposite operation.

When the adapter AD is used, the opening member 664 slightly opens the adapter AD to the extent that the electronic component ED can be held in the adapter AD. For this reason, as shown in the extracted view of FIG. 27 , the opening member 664 has a pusher 664a that can move forward and backward by the driving source 664b. Here, the pusher 664a slightly pushes the operating member OE while the clamping member 661 clamps the adapter AD to open the adapter AD, so that the electronic component ED can move backward while being held by the adapter AD. That is, the opening member 664 provided on the test hand 660 opens the adapter AD only to the extent that the electronic component ED can move rearward without being separated from the adapter AD. Therefore, the electronic component ED can move backward while still being loaded on the adapter AD.

As shown in the extracted view of FIG. 28 , the pusher 665a of the connecting member 665 that moves forward and backward by the operation source 665b pushes the electronic component ED backward so that the portion of the electronic component ED on the contact terminal T side can be inserted into the test slot S.

For reference, in this embodiment, the test hand 660 is configured to hold the electronic component ED or the adapter AD whose posture is converted from a horizontal position to an upright position through the converter 640. However, depending on the shape of the test slot S, the test hand 660 may also be Implemented to hold horizontal electronic components ED or adapters AD. ＜Explanation of the transfer part＞

FIG. 29 is a schematic perspective view of the transfer part TP.

The transfer part TP is located substantially below the front side of the connection part CP, and is equipped to ride on the stacker part SP and the connection part CP. The transfer part TP receives the customer pallet CT loaded with the electronic component ED to be tested from the conveyor 400 of the stacker part SP, and moves the customer pallet CT to the supply position FP where the moving hand 620 can clamp the electronic component ED (refer to FIG. 21), and returns the customer pallet CT loaded with the tested electronic component ED from the recovery position RP (refer to Figure 21) to the stacker section SP. For this purpose, the transfer part TP is equipped with a supplier 710, a collector 720, five supply lifters 731, three recovery lifts 732, and a transfer device 740. In these structures, the feeder 710 and the collector 720 are located on the stacker part SP side, and the lifters 731, 732 and the transferer 740 are located on the connection part CP side.

The supplier 710 is provided to supply the customer tray CT received from the conveyor 400 and loaded with the electronic component ED to be tested to the transfer unit 740 . Referring to the extracted view of FIG. 30 , this supplier 710 is equipped with a moving plate 711 capable of loading customer pallets CT, since the moving plate 711 is provided to be able to travel to and from the area (stacker section side) where the conveyor 400 operates and The area in which the transfer unit 740 operates (the connecting portion side) allows the customer trays CT received from the conveyor 400 to be supplied to the transfer unit 740 .

The collector 720 is provided to collect the customer tray CT loaded with the tested electronic component ED received from the transfer unit 740 and transfer the customer tray CT to the conveyor 400 . Similarly, the collector 720 also has the same structure as the supplier 710 and can transfer the customer tray CT received from the transfer unit 740 to the conveyor 400 .

Each of the five supply lifters 731 on the supply line side has a supply lift plate 731a on which the customer pallet CT can be placed, as shown in the extracted view of FIG. 31 . Furthermore, the supply lifting plate 731a is raised and lowered by the lifting source 731b. Therefore, with the transfer device 740, the customer tray CT placed on the supply lifting plate 731a can be raised to a height where the moving hand 620 can clamp the electronic component ED located on the customer tray CT. Furthermore, when the raised customer tray CT is fixed by a holder (not shown) provided at the connection part CP, the supply lifting plate 731a is lowered again, so that the supply lifting plate 731a can be in a state that does not interfere with the operation of the transfer device 740 .

When all the electronic components ED that have been tested by the operation of the moving hand 620 are loaded on the customer pallets CT, the collecting lifter 732 lowers the customer pallets CT, so that the transfer device 740 can move the customer pallets CT to the collector 720 . This recovery lift 732 also has a recovery lift plate 732a, and its structure is the same as that of the supply lift 731.

The transferer 740 moves the customer tray CT loaded with the electronic component ED that needs to be tested from the supplier 710 to the supply elevator 731, and moves the customer tray CT loaded with the electronic component ED that has been tested from the recycling elevator 732. Recycler 720. In addition, the transfer device 740 plays the following role: if the customer tray CT placed on the supply lift plate 731a is emptied, the transfer device 740 moves the emptied customer tray CT to the recovery lift plate 732a, so that the electronics that have completed the test can Part ED can be loaded on customer pallet CT. As shown in the extracted view of FIG. 32 , such a transfer device 740 has a pair of clamping rods 741 a and 741 b for clamping the customer tray CT or releasing the clamping. Of course, the clamping rods 741a and 741b can move in the left-right direction, the front-rear direction, and the vertical direction.

Next, the transfer flow of the cover tray, the customer tray CT, and the electronic component ED formed in the connection part CP will be described. ＜Instructions on the cover tray transfer process＞

The cover pallets are loaded into the sorting machine HR together with the customer pallets CT in bundle units via the loading and unloading stacker 100 . Depending on the load level of the sorting machine HR, the customer pallet CT can pass through the storage stacker 200 or not pass through the storage stacker 200. Therefore, the cover pallet can also pass through the storage stacker 200 or not pass through the storage stacker 200. . 1. Without passing through the storage stacker

The conveyor 400 uses the second gripper 420 to clamp the cover tray from the customer pallet CT in the bundle unit located in the entry/exit stacker 100 , and then transfers the cover tray to the buffer stacker 500 . Thereafter, while the conveyor 400 is at rest, the conveyor 400 transfers the cover pallets located in the buffering stacker 500 to the stacker 300 , and the cover pallets located in the stacker 300 remain in the stacker 300 or from the sorting machine. HR moved out. Of course, considering the current capacity of the buffering stacker 500 , the cover trays may continue to remain in the buffering stacker 500 . 2. Passing through a storage stacker

The conveyor 400 transfers the customer pallets CT in bundle units covered with the cover pallet located in the entry/exit stacker 100 to the storage stacker 200 using the first gripper 410 . At this time, the lid tray is also transferred from the entry/exit stacker 100 to the storage stacker 200 . Then, the conveyor 400 uses the second gripper 420 to clamp the lid tray from the customer tray CT in the bundle unit located in the storage stacker 200, and then transfers the lid tray to the buffer stacker 500, and then transfers the lid tray to the buffer stacker 500. While the machine 400 is at rest, the cover pallet located in the buffering stacker 500 is moved to the stacker 300 . In addition, the cover tray located in the stacker 300 remains in the stacker 300 or is unloaded from the sorting machine HR. Similarly, the cover tray may remain in the buffering stacker 500 .

For reference, when the customer pallets CT that have been tested subsequently pass through the storage stacker 200 and the entry/exit stacker 100 and are unloaded from the sorting machine HR in bundle units, the execution conveyor 400 is located at the stacker 300 or The operation of covering the upper side of the customer pallet CT loaded in bundle units with the cover pallet of the buffer stacker 500. Then, the customer pallets CT in bundle units covered with the cover pallet in this way are carried out from the sorting machine HR. ＜Explanation of the basic transfer process for customer pallets＞ 1. Without passing through the storage stacker

Customer pallets CT in bundle units are loaded into the sorting machine HR via the loading and unloading stacker 100 . When there is a lid tray, the conveyor 400 first moves the lid tray to the buffering stacker 500 using the second gripper 420 . Then, the conveyor 400 uses the second gripper 420 to take out the customer pallets CT one by one starting from the uppermost customer pallet CT in the entry/exit stacker 100 and supplies them. to the supplier 710 which transfers the part TP. Furthermore, the customer tray CT of the supplier 710 is moved to the supply position FP by the operation of the supplier 710 and the transfer device 740, and is raised by the supply lifter 731. Thereafter, in a state where the customer tray CT is fixed by the holder located at the connection part CP, the loaded electronic components ED are emptied by the moving hand 620 . Accordingly, the customer tray CT in which all the electronic components ED have been emptied is lowered by the supply lifter 731 , is moved to the recovery position RP by the transfer device 740 , and is then fixed by the holder while being raised by the recovery lifter 732 . Then, the moving hand 620 performs an operation of loading the tested electronic components ED to the empty customer pallet CT located at the recovery position RP, and the customer pallet CT loaded with the tested electronic components ED is lowered by the recovery lifter 732, and then borrowed It moves to the stacker part SP by the transferer 740 and the collector 720 . Next, the conveyor 400 moves the customer pallets CT from the recycler 720 to the entry/exit stacker 100. When the customer pallets CT are loaded into the entry/exit stacker 100 in bundle units, they are covered with the cover pallet and are then separated from the sorter HR. Move out in bundles. 2. Passing through a storage stacker

When the customer pallets CT in bundles are carried into the sorter HR through the entry/exit stacker 100 , the conveyor 400 removes the customer pallets CT in bundles from the entry/exit stacker using the first gripper 410 100 moves to the storage stacker 200 to empty the access stacker 100 . Therefore, the loading and unloading stacker 100 can accommodate the amount of loading cargo supplied one after another.

In addition, when it is necessary to supply the customer pallets CT located in the storage stacker 200 to the connection part CP, the conveyor 400 supplies the customer pallets CT in single sheets to the transfer part TP using the second gripper 420 . Of course, if there is a cover tray in this case, the conveyor 400 first moves the cover tray to the buffering stacker 500 using the second gripper 420 .

Then, after the customer pallet CT moves to the supply position FP in the same flow as described above, it passes through the recovery position RP and is recovered to the collector 720 again. Similarly, the customer pallets CT collected by the collector 720 are moved to the storage stacker 200 via the conveyor 400. When the customer pallets CT are loaded into the storage stacker 200 in bundle units, the pallets are covered with After covering, it moves to the loading and unloading stacker 100, and is then carried out from the sorting machine HR. ＜Transfer process of electronic components in the connection section＞

The movement of the electronic component ED in the stacker section SP and the transfer section TP is performed together with the movement of the customer pallet CT described above.

In addition, the electronic component ED that needs to be tested located at the supply position FP is moved by the moving hand 620 and placed on the shelf 610 located in the first working area W1. Then, the reciprocator 650 moves the shelf 610 to the rear second working area W2, so that the electronic component ED also moves to the second working area W2. Then, the converter 640 rotates the shelf 610, thereby converting the posture of the electronic component ED placed on the shelf 610 from the horizontal position to the upright position.

Furthermore, the electronic component ED that has been transformed into an upright posture is held by the test hand 660 and electrically connected to the tester TESTER. The electronic component ED that has been tested is recovered from the tester TESTER by the test hand 660 and then placed in the shelf 610 . Next, the converter 640 reversely rotates the shelf 610 so that the upright electronic component ED becomes a horizontal position, and the moving hand 620 moves the horizontal electronic component ED that has completed the test from the shelf 610 to the customer tray located at the recovery position RP. CT. ＜References＞ 1. Number of stackers

In this embodiment, five stackers 100 for entry and exit, stackers 200 for storage, and stackers 300 are each provided. However, one or more stackers may be provided depending on the processing capacity of the sorting machine HR. Furthermore, the storage stacker 200 may be arranged in multiple stages above the entry/exit stacker 100 to increase the processing capacity. 2. Supplementary instructions for the process of customer pallets

The above customer pallet CT process only illustrates the most basic process.

Therefore, even if the storage stacker 200 is not used on the path where the customer pallets CT carried into the sorter HR are supplied to the connection part CP, the storage stacker 200 can be used on the path where the customer pallets CT are carried out.

Similarly, even if the storage stacker 200 is used on the path on which the customer pallets CT carried into the sorter HR are supplied to the connection part CP, the storage stacker 200 may not be used on the path on which the customer pallets CT are carried out. Palletizer 200.

That is, according to the present invention, by providing the storage stacker 200 and the stacker 300 independently of the entry and exit stacker 100, the flow of customer pallet CT can be realized in a very diverse combination, and the flow of customer pallet CT can be improved to a corresponding degree. Efficiency. 3. Supplementary instructions for stackers

According to the existing general sorter technology, it is divided into a stacker that carries in customer pallets CT and a stacker that carries out customer pallets CT (for example, it is divided into a stacker for loading and a stacker for unloading), and its layout The location is fixed.

However, according to the present invention, it is divided into only the stacker 100 for entry and exit and the stacker 200 for storage. Furthermore, depending on the situation at that time, the loading and unloading stacker 100 may be used for loading the customer pallets CT into the sorting machine HR or for carrying out the customer pallets CT from the sorting machine HR. That is, the loading and unloading stacker 100 can be selectively used for loading or unloading according to the current situation. Therefore, the efficiency of customer pallet CT transfer operations will be greatly improved.

Of course, the storage stacker 200 can also be used selectively in response to the current situation. 4. Identification of customer pallets based on bundles

When the conveyor 400 transfers the customer pallets CT in bundles from the entry/exit stacker 100 to the storage stacker 200, it can realize an identification code (for example, a barcode) that identifies the customer pallets CT in bundles. . In this way, by identifying the customer pallets CT in the bundle unit, the customer pallet CT can be managed in the unit of bundles, so it can be considered as a preferable method. 5. Identify customer pallets in units of sheets and confirm the placement status of electronic components

When the customer pallets CT in units of single sheets are moved from the stacker part SP to the connection part CP through the transfer part TP, each customer pallet CT can be identified by identifying the identification code (for example, a barcode) possessed by it. Each customer pallet CT manages electronic components ED.

Furthermore, it is preferably implemented so that the placement state of the electronic component ED is confirmed using a camera when the customer pallet CT in single sheet units is moved from the stacker part SP to the connection part CP via the transfer part TP.

In this way, when the customer pallets CT in units of single sheets are moved by the transfer part TP, it is possible to identify the customer pallets CT and confirm the placement status of the electronic components ED, so that it can be performed with only a minimum number of identification devices and confirmation devices. It is possible to reduce production costs by identifying customer pallets with CT and confirming the placement status of electronic components ED. 6. Expansion of processing capacity

The sorter HR according to the present invention can expand the processing capacity by combining another connection part CP and the transfer part TP on the right side of the connection part CP and the transfer part TP, and the expansion of the processing capacity can be realized with the storage of the stacker part SP The capacity is the same. 7. Matters regarding electronic components processed

In the present invention, a solid-state drive is cited as an example of the large electronic component ED, but the sorter according to the present invention is not limited to processing solid-state drives. 8. Types of solid state drives

FIG. 33 illustrates various forms of solid-state drives as a type of electronic components.

That is, the solid-state drive can have various sizes depending on the functions and specifications of the finished product to which it is applied. Therefore, a large-sized solid-state drive can be directly placed on the shelf 610 , but a smaller-sized solid-state drive cannot be directly placed on the shelf 610 . Therefore, the application adapter AD is required for resting the small-sized solid-state drive on the shelf 610 . 9. Rotation direction of electronic components

Since the test slot S of the tester TESTER is formed long in the up-down direction, when the solid-state drive as the electronic component ED is in a lying state, the terminal T side of the solid-state drive cannot be inserted into the test slot S. That is, as shown in (a) of FIG. 34 , this is because the terminals T on the terminal T side of the horizontal solid-state actuator are arranged long in the left-right direction. Therefore, in this embodiment, the horizontal solid-state actuator is rotated and converted into an upright position, so that the terminals T become in an attitude in which they can be arranged in a long vertical direction. Through this attitude transformation, the bit on the side of the terminal T of the solid-state drive can be inserted into the test slot S.

Therefore, according to this embodiment, the mobile hand 620 clamps the horizontal solid-state drive from the customer tray CT in a vacuum suction manner, moves it to the shelf 610, and rotates the shelf 610 90 degrees through the converter 640, thereby placing the The solid-state drive placed on the shelf 610 in a horizontal position is converted into an upright position. Furthermore, the test hands 660 hold both ends of the vertical solid-state drive (or an adapter equipped with the solid-state drive), and then electrically connect it to the tester.

Here, the solid-state driver by the converter 640 should be rotated in a direction such that the portion on the terminal T side can be inserted into the test slot S. This is explained in more detail with reference to (a) and (b) of FIG. 34 .

In (a) of FIG. 34 , the solid-state actuator as the electronic component ED is in a horizontal state. That is, the wide surface faces upward or downward, and a long terminal T is formed at the rear in the left-right direction.

In the state of FIG. 34(a) , the terminal T side is divided into two parts by dividing a long straight line in the front-rear direction (the direction in which the fixed actuator moves when the terminal side part of the solid-state actuator is inserted into the test slot). The half imaginary line serves as the rotation axis RS and rotates the solid-state actuator 90 degrees, thereby converting the solid-state actuator into an upright shape with the wide surface facing the left and right directions as shown in (b) of FIG. 34 . 10. Supplementary instructions for adapters

The adapter AD may have various placement structures depending on the type of electronic component ED.
