Description

Sorting machine for electronic component testing

The present invention relates to a sorter for electronic component testing that supports the supply of electronic components to a tester for testing.

The electronic components produced (such as SSD, circuit substrate, semiconductor components, etc.) are divided into good products and defective products after being tested by the tester, and only good products are released from the warehouse.

Electronic components can only be tested by being electrically connected to a tester. At this time, the equipment that supports testing electronic components by electrically connecting electronic components to a tester is a sorter for electronic component testing (hereinafter referred to as "handler"). Therefore, the sorter has a stacker for recovering tested electronic components after supplying the electronic components to be tested to the tester side.

The stacking mechanism is configured to accommodate customer trays on which electronic components to be tested are placed or customer trays on which tested electronic components are placed. And, the customer tray carried into the sorting machine from the outside or the customer tray carried out from the sorting machine goes through a process of being stored in the stacker.

In the past, the work of loading and unloading customer pallets into and out of the sorting machine was carried out directly by the operator. Until the introduction of automated systems (OHT or AGV, etc.), it is possible to automatically move customer pallets into and out of the sorting machine.

In addition, most electronic components have an orientation for electrical connection with a tester. Therefore, electronic components need to be supplied to the tester in a specific orientation. Therefore, customer trays with electronic components also need to be moved into the sorting machine in a specific direction.

However, depending on the type of electronic components, the directionality of the customer trays supplied to the sorting machine by the automation system varies, and there may be a problem that customer trays cannot be supplied to the sorting machine by the conventionally installed automation system.

In addition, multiple customer pallets are moved into the sorting machine in bundles by the automation system. If the stacker on the loading path is filled with customer pallets, it is impossible to load more customer pallets into the sorting machine. Factors that limit the increase in processing speed and processing capacity.

The sorting machine according to the present invention is more suitable for the case where the contact terminal side of an electronic component such as a solid state drive (SSD: Solid State Drive) is inserted into a test slot of a tester.

For example, as shown in FIG. 1 , a tester (TESTER) is provided with a test slot S, and the electronic component ED is electrically connected to the tester (TESTER) by inserting the portion on the terminal T side of the electronic component ED into the test slot S. <Schematic description of the overall structure of the sorter>

FIG. 2 is a schematic plan view of a sorting machine HR according to an embodiment of the present invention, and FIG. 3 is a schematic perspective view of the sorting machine HR of FIG. 2 .

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

The stacker section SP accommodates customer trays CT on which electronic components ED are placed. This stacker part SP is used to receive from the outside customer trays CT on which electronic parts ED to be tested are placed, or to transfer to the outside customer trays CT on which electronic parts ED that have been tested are placed. In addition, the stacker part SP is also used for storing customer trays CT carried in or out from the outside. For this reason, as shown in the schematic sectional view of Figure 4, the stacker part SP includes 5 access stackers 100, 5 storage stackers 200, 5 sorting stackers 300, and conveyors. 400, these will be described in detail in the following table of contents.

The connection part CP takes out the electronic components ED from the customer tray CT delivered by the stacker part SP and electrically connects them to the tester (TESTER), or sorts the electronic components ED tested by the tester (TESTER) according to the test level and places them on the customer Tray CT.

The transfer device TA transfers the customer tray CT between the stacker part SP and the connection part CP. That is, the customer tray CT on which the electronic component ED to be tested is placed is supplied from the stacker part SP to the connection part CP by the transfer device TA, and the customer tray CT on which the tested electronic part ED is placed is collected from the connection part CP by the transfer device TA. to stacker section SP.

The connection part CP and the transfer device TA described above are described in detail in Korean Application No. 10-2020-0073725, which is the applicant of the present application, and thus detailed description thereof will be omitted.

For reference, "outside" and "inside" described in the following description are defined based on the arrangement relationship between the stacker and the conveyor described later. That is, the side from the conveyor toward the stacker (the left side in the plan view of FIG. right side in plan). ＜Explanation for access stacker＞

The access stackers 100 all have the same structure, and five are arranged side by side in the horizontal direction (the front-back direction based on FIG. 2 ).

The access stacker 100 is used to receive from the outside customer trays CT in bundles on which electronic components ED to be tested are placed, or to transfer customer trays CT in bundles to which electronic components ED that have been tested are placed. to the outside. That is, each of the five loading and unloading stackers 100 can be used to carry customer trays CT into the sorter HR, or can be used to carry customer trays CT out of the sorter HR according to control. To this end, as shown in the sectional view of FIG. 5 and the exploded perspective view of FIG. 6 , the access stacker 100 includes a storage device 110, a first shutter 120, a moving plate 130, a base plate 140, a first front and rear mover 150, a rotating The device 160 and the first mover 170.

The storage unit 110 can store customer trays CT in bundles. That is, a plurality of customer trays CT carried into and out of the sorter HR by the operator or the automation system are configured as a bundle. In addition, depending on circumstances, the uppermost customer tray CT may be covered with a separate tray cover. Therefore, the storage device 110 needs to ensure the first storage space S1 so that it can store the customer tray CT received from the outside or sent to the outside in units of bundles. To this end, the container 110 includes first supports 111 o , 111 i and a rotating plate 112 .

The first supports 111o and 111i support the side surfaces of the corners of the four sides of the customer tray CT, and prevent the customer tray CT stored in the first storage space S1 from detaching. Therefore, the 1st support body 111o, 111i forms the 1st storage space S1 which can accommodate the customer tray CT inside the edge which connects these.

The rotary plate 112 is rotatably arranged, and the rotary plate 112 is provided with a conveyor belt 171 which will be described later as a first shutter 120 and a first mover 170 . Obviously, the customer tray CT is placed on the conveyor belt 171 . In addition, the first support members 111 o and 111 i are fixedly disposed on the rotating plate 112 .

The first shutter 120 rotates the first support member 111i located in the inner direction of the sorter HR forward or reversely, so that the first support member 111i can support the corners of the four sides located in the inner direction of the customer tray CT. side, or as shown in the reference view of Figure 7, unsupport that side. At this time, if the first support member 111i is in the state of releasing the support of the corners of the four sides located in the inner direction of the customer tray CT, the first storage space S1 is opened in the inner direction, so that the customer tray CT can move in the inner direction. state.

The moving plate 130 is equipped to be movable toward 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 movable plate 130 is rail-coupled to the base plate 140 so as to be movable toward the inner and outer directions. Furthermore, the base plate 140 is provided with the second air cylinder 153 of the first forward and backward mover 150 to be described later, the operation motor 172 of the first mover 170 , and the like.

As shown in the conceptual diagrams referring to (a) and (b) of FIG. The retracting movement of the container 110 is restored to the original position as shown in FIG. 8( b ). According to the present embodiment, the storage stacker 200 is positioned above the entry/exit stacker 100 . Therefore, it is difficult for a worker or an automated system to store the customer tray CT in the stocker 110 or collect the customer tray CT stored in the stocker 110 . In order to solve such a problem, in this embodiment, the first forward and backward mover 150 moves the storage device 110 forward to the outside of the sorter HR, so that the operator or the automation system can store the customer tray CT in the first storage space S1 or a state in which customer trays CT are collected 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 storage device 110 back to the inside of the sorter HR, thereby moving the storage device 110 to the inside of the sorter HR. Return to original position. For this purpose, as shown in the sectional 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 air cylinder 151 is coupled to the moving plate 130, when the first air cylinder 151 operates, the moving plate 130 moves inwardly and outwardly once.

The support plate 152 is track-coupled to the base plate 140 in a manner capable of moving inward and outward. A first air cylinder 151 is fixedly provided on such a support plate 152 .

The second cylinder 153 is fixed on the base plate 140 , and the piston rod of the second cylinder 153 is combined with the support plate 152 . Therefore, when the second air cylinder 153 operates, the support plate 152 moves inwardly and outwardly, so that the moving plate 130 performs secondary movement.

As mentioned above, the moving plate 130 can be moved repeatedly by using the two air cylinders 151 and 153 , so that the moving distance of the container 110 can be sufficiently ensured.

The rotator 160 rotates the rotating plate 112 forwardly or backwardly at an angle of 90 degrees. Therefore, considering the direction of electrical connection between the electronic component ED and the tester (TESTER), even if the direction of the customer tray CT supplied by the conventional automation system is supplied with a difference equivalent to 90 degrees, it can be passed through the rotator The operation of 160 corrects the orientation of the customer tray CT. For example, when the conventionally installed automation system supplies customer trays CT in the correct direction, it is not necessary to operate the spinner 160 . However, in case the conventionally installed automation system supplies customer trays CT in a direction different from the normal direction by 90 degrees, as shown in the conceptual diagram with reference to FIG. After the forward rotation of 90 degrees, if the customer tray CT is stored in the first storage space S1, then the reverse rotation of 90 degrees is performed again, so that the direction of the customer tray CT can be corrected. Therefore, no matter what kind of electronic components ED are, the conventionally installed automation system can be directly used to smoothly carry the customer tray CT into the sorting machine HR, or smoothly carry out the customer tray CT from the sorting machine HR. Of course, in order to minimize the installation space, it is preferable to implement and control the rotation of the rotator 160 only when the container 110 advances to the outside of the sorter HR.

For reference, in this embodiment, the rotator 160 is constituted by the air cylinder 161, the rack 162, the pinion 163, etc., but any form can be appropriately applied as long as it is a structure that can rotate the rotatable plate 112 according to the embodiment. .

The first mover 170 is configured to move the bundle-based customer trays CT stored in the storage unit 110 inwardly to withdraw the customer trays CT from the first storage space S1, or to move the customer trays conveyed from the inside CT moves outward, and the customer tray CT enters into the 1st storage space S1. In this embodiment, as shown in the sectional view of FIG. 11 , although the first mover 170 is implemented with a conveyor belt 171, as long as it is a structure that can move the customer tray CT in the unit of a bundle to the inside and outside, it does not need to be moved. Limited to conveyor belt structures. Such a first mover 170 has an operating motor 172 for operating the conveyor belt 171 , a rotating shaft 173 , and a power transmitter 174 .

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

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

The power transmitter 174 transmits the rotational force of the rotating 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. 173T and the moving shaft 173M can be separated from each other by being coupled or disengaged. Therefore, when the moving plate 130 is in the state of moving forward, backward or outward, as shown in (a) of FIG. The open state prevents interference between the rotating shaft 173 and the moving plate 130 . Of course, in the state where the moving plate 130 returns to its original position, especially when the first mover 170 operates to withdraw the customer tray CT in bundles from the first storage space S1, as shown in (b) of FIG. As shown, the moving shaft 173M needs to be raised by the lifting member 175 so that the moving shaft 173M is combined with 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 running motor 172 , and the upper shaft 173T is geared to the power transmitter 174 side.

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

First, when the customer tray CT is supplied in units of bundles by a worker or an automated system, the first forward and backward mover 150 is operated to move the storage unit 110 forward toward the outside of the sorter HR. In this state, the customer tray CT in units of bundles is loaded in the first storage space S1 while descending from above to below. At this time, if the direction of the customer tray CT needs to be corrected, before the customer tray CT descends, the rotator 160 is operated in advance, so that the container 110 is rotated forward at an angle of 90 degrees. When the CT is stored in the first storage space S1, the rotator 160 operates in the reverse direction, and the container 110 rotates in the reverse direction at an angle of -90 degrees.

When customer trays CT in bundles are stored in the first storage space S1, the first forward and backward mover 150 operates to move the storage device 110 backward toward the inside of the sorter HR, thereby restoring the storage device 110 to its original position. Location.

In addition, when it is necessary to move the bundle-based customer tray CT located in the first storage space S1 inwardly, the first shutter 120 operates to rotate the first support member 111i located inward in the forward direction, thereby moving inwardly. The direction opens the first storage space S1. Then, in this state, the first mover 170 operates to move the bundle-unit customer trays CT inward, and the bundle-unit customer trays CT exit from the first storage space S1 inwardly. ＜Explanation for storage stackers＞

The stacker 200 for storage has the same structure, and is used to store customer trays CT in bundles received from the outside by the stacker 100 for access, or to transfer the pallets CT to the outside by the stacker 100 for access. The customer tray CT in the bundle unit is stored or the like before being transferred to the stacker 100 for loading and unloading. For this purpose, the storage stacker 200 includes four second supports 211o, 211i, a second shutter 220, and a second mover 270, as shown in a cutaway view of FIG. 13 .

The four supports 211o, 211i support the corners of the four sides of the customer tray CT, and form the second storage space S2 capable of storing the customer tray 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, so their descriptions are omitted. ＜Explanation for sorting stackers＞

The stackers 300 for sorting all have the same structure, and are located on the lower side of the stacker 100 for entry and exit. Such a stacker 300 for sorting has substantially the same structure as the stacker 200 for storage, and thus detailed description thereof will be omitted.

The sorting stacker 300 can be applied to various uses as exemplified below.

For example, when the tray cover covers the uppermost customer tray CT among the customer trays CT in units of bundles, any one of the sorting stackers 300 can be used for storing the tray cover.

For example, the sorting stacker 300 can be used for storing customer trays CT on which a small number of electronic components ED judged to be defective are placed.

For example, the stacker 300 for sorting can be used for sorting good electronic components ED by test level and temporarily storing them.

For example, when it is difficult to move the customer tray CT by the current access stacker 100 or the storage stacker 200 , the sorting stacker 300 can be used for temporary waiting.

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

In addition, for this kind of stacker 300 for sorting, it can be considered that the storage capacity of the customer tray CT equipped with it is smaller than that of the stacker 100 for access or the stacker 200 for storage, so as to prevent the sorter from The hugeness of HR. ＜Explanation for the conveyor＞

The conveyor 400 is equipped to move customer trays CT in the stacker section SP in one go by moving customer trays in bundles between the stacker 100 for loading and unloading and the stacker 200 for storage. CT, or the customer tray CT on the stacker 100 for entry and exit or the stacker 200 for storage is supplied to the transfer device TA in units of sheets (referring to one sheet). Of course, the conveyor 400 also moves the customer trays in single sheets transferred by the transfer device TA to the stackers 100 , 200 , 300 . For this, as shown in the cutaway view of FIG. 14 , the conveyor 400 includes a first gripper 410 , a second gripper 420 , an elevator 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 customer tray CT in bundles at one time. To this end, as shown in the sectional view of FIG. 15 , the first clamper 410 includes third supports 411 o , 411 i , a third shutter 412 , and a third mover 413 .

The third supports 411o and 411i support the side surfaces of the four corners of the customer tray CT in bundle units, and form a storage space S3 inside which the customer tray CT in bundle units can be accommodated. Such third support members 411o, 411i are combined and disposed on the upper surface of the combination plate JP.

The third shutter 412 rotates the third support member 411o located in the outer direction, so that the bundle-based customer tray CT horizontally moving 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 411 o by the operation of the third shutter 412 .

The third mover 413 is equipped to horizontally move customer trays CT in units of bundles entering or exiting the storage space S3, and in the same manner as the first mover 170 in this embodiment 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 clamper 410 and the second clamper 420 are arranged in parallel in the vertical direction, and are coupled to each other by installing the coupling plate JP. That is, the first clamper 410 is also disposed on the joint plate JP, and the second clamper 420 is also disposed on the joint plate JP.

The second clamper 420 can clamp or release the customer tray CT in units of sheets. To this end, as shown in the sectional view of FIG. 16, the exploded perspective view of FIG. 17 and the partial sectional view of FIG. Rod 423 , a pair of pitch adjustment sources 424 , and a second back and forth mover 425 .

The first forward-backward moving plate 421 is rail-coupled to the joint plate JP in a manner capable of moving forward and backward in the inner and outer directions.

The second forward and backward moving plate 422 is track-coupled with the first forward and backward moving plate 421 in a manner capable of moving forward and backward in the inner and outer directions.

A pair of clamping rods 423 are provided on the second forward-backward moving plate 422 so as to face each other in the front-back direction in the drawing, and have clamping hooks GH for clamping customer trays CT in units of sheets.

A pair of spacing adjustment sources 424 provides power for reducing or expanding the spacing between a pair of clamping rods 423 . Therefore, depending on the operating state of the pair of pitch adjustment sources 424, the pair of clamp levers 423 is in a state of clamping the customer tray CT or in a state of releasing the clamp.

The second forward and backward mover 425 provides a forward and backward moving force to enable 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 back and forth mover 425 has a double conveyor belt structure, and includes a driving motor 425a, a first conveyor belt 425b, and a second conveyor belt 425c.

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

The first conveyor belt 425b is disposed on the joint plate JP. Furthermore, the first front-back movement plate 421 is coupled to the first conveyor belt 425b, and the first front-back movement plate 421 linearly moves inwardly and outwardly by the cyclic rotation of the first conveyor belt 425b.

The second conveyor belt 425c is disposed on the first front and rear moving plate 421 . And, the second forward and backward movement plate 422 is coupled to one side point P1 of the second conveyor belt 425c, and the coupling member JE is attached to the other side point P2 to be coupled to the coupling plate JP. Here, in order to eliminate interference between the connecting member JE and the first forward-backward moving plate 421 , a through hole TH through which the connecting member JE can pass is formed long in the inner-outer direction in the first forward-backward moving plate 421 .

As a reference, it is preferable to consider that the second clamper 420 is equipped with a pressure plate PP elastically supported by an elastic member E such as a spring to realize the elasticity on the upper surface of the clamped customer tray CT. Pressurized for stable clamping of customer trays CT. Of course, the elastic member E is provided between the pressure plate PP and the second back and forth moving plate 422 .

Then, the customer tray CT is transferred to the connection part CP by the transfer device TA.

When the customer tray CT is moved to the connection part CP and located at the desired position, the electronic parts ED placed on the customer tray CT are finally taken out one by one through the operation of the connection part CP, and then supplied to the tester (TESTER) to be emptied Customer Tray CT. The tested electronic components ED are classified according to grades and placed on empty customer trays CT, and the customer trays CT filled with tested electronic components ED are transferred to the stacker part SP by the transfer device TA. Then, the conveyor 400 moves the corresponding customer tray CT to the stacker 100 for entry and exit using the second gripper 420 . 2. In the case of a stacker for storage

If the customer tray CT in bundles is carried into the sorting machine HR by the stacker 100 for loading and unloading, the conveyor 400 uses the first gripper 410 to transfer the customer trays CT in bundles as a unit from the stacker for loading and unloading. 100 moves to the stacker 200 for storage, and the stacker 100 for entry and exit is emptied. Therefore, the stacker 100 for loading and unloading can accommodate the quantity of incoming goods supplied successively.

In addition, when it is necessary to supply the customer tray CT located in the storage stacker 200 to the connection part CP, the conveyor 400 supplies the customer tray CT in the unit of sheet to the transfer device TA using the second gripper 420 . Of course, if there are still tray covers in this case, the conveyor 400 first uses the second gripper 420 to move the tray covers to any one of the sorting stackers 300 .

And, after the customer tray CT on which the electronic component ED to be tested is placed is supplied to the connection part CP by the transfer device TA, if the customer tray CT on which the tested electronic part ED is placed is transferred from the connection part CP to the stacker by the transfer device TA SP, the conveyor 400 uses the second gripper 420 to move the customer tray CT to the stacker 200 for storage. Afterwards, when the customer tray CT in bundles is stored in the stacker 200 for storage, the conveyor 400 uses the first gripper 410 to transfer the customer tray CT in bundles from the stacker 200 for storage to the stacker 200 for storage. The stacker 100 for entry and exit, and the customer trays CT in bundles stored in the stacker 100 for entry and exit are carried out from the sorter HR by a worker or an automated system. ＜References＞ 1.

Supplementary instructions for the stacker

According to the existing general sorting machine technology, the arrangement position of the stacker that carries in the customer tray CT and the stacker that carries out the customer tray CT (for example, divided into a stacker for loading and a stacker for unloading) is fixed.

However, according to the present invention, only the stacker 100 for access and the stacker 200 for storage are classified. In addition, depending on the situation at the time, the stacker 100 for loading and unloading can be used for loading the customer tray CT into the sorting machine HR, or can be used for unloading the customer tray CT from the sorting machine HR. . That is, the stacker 100 for carrying in and out can be selectively used for carrying in or carrying out according to the current situation. Therefore, the efficiency of the transfer operation of the customer tray CT will be greatly improved.

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

When the conveyor 400 transfers the customer tray CT in units of bundles from the stacker 100 for storage to the stacker 200 for storage, it can be realized as an identification code (for example, a barcode) for identifying the customer tray CT in units of bundles. . In this way, since customer trays CT can be managed in units of bundles by recognizing customer trays CT in units of bundles, the above-mentioned aspect can be considered preferably. 5. Identification of customer trays in units of sheets and confirmation of placement status of electronic components
