Description

Tray processing assembly

Technical Field

The application relates to the technical field of semiconductor testing, in particular to a tray processing assembly.

Background

The semiconductor test tray is used as a key packaging structure required by semiconductor package to prevent electrostatic touch of products, protect chips from being damaged, and facilitate automatic detection and installation. In practical use, it is necessary to equip the test tray adapted to different types of chips and to mount the chip-mounted test tray to a rack for performance testing of the chips. When different test trays are assembled relative to the rack, model identification needs to be performed on the test trays to confirm chip information.

At present, when the test tray is identified, the depth of the identification groove on the test tray is identified by utilizing the identification block in a matching mode of the identification groove and the identification block so as to distinguish the test trays with different models. However, this approach requires different depths of identification slots for different test trays, and the number of test trays is large, manufacturing is unchanged, and cost is high.

Disclosure of Invention

Based on this, it is necessary to provide a tray handling assembly that is simple to manufacture and low in cost, while satisfying the recognition of different test trays.

The tray processing assembly is used for being mounted on the rack and comprises a test tray, a plug and an induction component; the test tray is provided with a plurality of detection holes which are arranged at intervals; the plugs are used for plugging the detection holes so as to adjust the opening states of the detection holes; wherein the open cell state includes open cells and closed cells; the induction component is arranged on the frame; the sensing assembly is configured to generate detection signals for characterizing different test trays in response to the open states of the plurality of detection holes; wherein the sensing assembly comprises a plurality of sensing elements, and the number of the sensing elements is not less than the number of the detection holes; when the test tray is assembled relative to the rack, each sensing element can correspondingly sense the opening state of one detection hole.

According to the tray processing assembly, the plurality of detection holes which are arranged at intervals are formed in the test tray, and the opening state of each detection hole is changed by plugging the plugs relative to the detection holes, so that the test tray with different types is represented; meanwhile, the open hole state of each detection hole is detected by using the sensing element in the sensing assembly, so that the information of the test tray can be identified. Because, when the open hole state of each detection hole is different, the detection information fed back by the corresponding sensing element is different, so that detection signals aiming at different test trays are obtained. Compared with the prior art that the depth of the identification groove on different test trays needs to be changed, the tray processing assembly provided by the utility model can meet the identification of different test trays only by adjusting the opening state of the detection hole by using the plug and by using the matching of the sensing element, and is convenient to operate, simple to manufacture and low in cost.

In one embodiment, the opening states of the plurality of detection holes are determined according to the number of plugs and the arrangement rule of the plurality of plugs relative to the detection holes.

It can be understood that whether the plug is mounted on the detection hole or not determines the opening state of the detection hole. Therefore, when the number of plugs is different, the number of the plugged detection holes is also different; and when the plugs plug the detection holes at different positions, the detection signals of the corresponding sensing elements are different. Thus, the setting of different test trays can be satisfied.

In one embodiment, the sensing element is triggered in a contact manner with respect to the plug; the sensing element is configured to generate a pressure signal responsive to a pressure change within the sensing bore.

It can be understood that whether the plug is installed in the detection hole can be judged by detecting the pressure condition between the plug and the hole wall of the detection hole.

In one embodiment, the sensing element is triggered in a non-contact manner relative to the plug; the inductive element is configured to generate a magnetic signal responsive to the plug; or, the sensing element is configured to generate an optical signal responsive to the plug; alternatively, the inductive element is configured to generate an electrical signal responsive to the plug.

It can be appreciated that by utilizing a non-contact triggering mode, the interference of the test tray and the plug relative to the induction element is reduced, the protection of the induction element is improved, and the service life of the induction element is prolonged.

In one embodiment, the sensing assembly further comprises a mounting substrate and a plurality of mounting arms spaced apart from the mounting substrate, each of the mounting arms being for coupling one of the sensing elements.

It will be appreciated that by the provision of a plurality of mounting arms, individual mounting and replacement of each sensing element is facilitated; meanwhile, the arrangement of the matched mounting substrate meets the requirement of integrated mounting of a plurality of sensing elements relative to the frame.

In one embodiment, each of the assembly arms has a first folding arm portion, a second folding arm portion, and a third folding arm portion, the first folding arm portion and the second folding arm portion being arranged at intervals in a thickness direction of the test tray, the third folding arm portion being connected between the first folding arm portion and the second folding arm portion, the first folding arm portion being used for mounting the sensing element, and the second folding arm portion being used for being connected to the mounting substrate.

It can be appreciated that the first folding arm portion and the second folding arm portion are separated by the third folding arm portion, so that the mounting space of the test tray relative to the rack is met, and meanwhile, the sensing requirement of the sensing element is met.

In one embodiment, the first fold arm and the second fold arm extend in opposite directions from a junction with the third fold arm.

It will be appreciated that this provides for installation space for the wire termination traces on the inductive element.

In one embodiment, each of the detection holes is provided through the test tray in a thickness direction of the test tray.

It can be appreciated that by arranging the detection hole as a through hole, a significant difference is formed between the detection hole and the installation plug, so that the detection device is convenient for not only artificial observation, but also detection of the sensing element.

In one embodiment, a groove is formed in the edge of the orifice of one end, facing away from the sensing element, of each detection hole, and the groove is recessed in a direction towards the sensing element; the plugs are arranged in the detection holes and the grooves; the bottom of the groove is provided with a fixing hole; the tray processing assembly further comprises a fixing piece, and one end of the fixing piece penetrates through the plug to be connected with the hole wall of the fixing hole.

It can be understood that the accommodating space of the plug is increased through the matching of the groove and the detection hole so as to be suitable for the plug with larger size; meanwhile, the plug is fixed relative to the test tray by matching with the fixing piece, so that the connection reliability is improved, and the plug is prevented from being separated.

In one embodiment, the plug is provided with an assembly hole for the fixing piece to penetrate through, and one end of the assembly hole, which is away from the induction element, is provided with a containing groove.

It can be understood that the fixing piece is more convenient to assemble relative to the plug through the arrangement of the assembly holes, and the accommodating groove is used for accommodating the fixing piece, so that interference of the fixing piece to other structures in the sorting machine is reduced.

The term "and/or" as used in the specification of this application includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-3, a tray handling assembly 100 according to an embodiment of the present utility model includes a test tray 10, a stopper 20, and a sensing assembly 30. The test tray 10 is provided with a plurality of detection holes 11 which are arranged at intervals, and plugs 20 are used for plugging the detection holes 11 so as to adjust the opening states of the plurality of detection holes 11; the open state of the plurality of detection holes 11 includes open holes and closed holes. The sensing assembly 30 is mounted on the rack 200, and the sensing assembly 30 is configured to generate a detection signal for characterizing different test trays 10 in response to the open states of the plurality of detection holes 11. The sensing assembly 30 includes a plurality of sensing elements 31, and the number of sensing elements 31 is not less than the number of detection holes 11; moreover, when the detection tray is assembled with respect to the rack 200, each sensing element 31 can correspondingly sense the opening state of one detection hole 11.

Specifically, when the open state of each detection hole 11 is different, the detection information fed back by the corresponding sensing element 31 is different, so that detection signals for different test trays 10 are obtained. For example, when the plug 20 is installed in a certain detection hole 11, the detection hole 11 is closed, and the sensing element 31 detects the information that the detection hole 11 is closed, and feeds back to the controller for analysis. Compared with the prior art in which the corresponding depths of the identification grooves are required to be set for different test trays 10, the tray processing assembly 100 provided in this embodiment can be configured to form the test holes 11 on each test tray 10 in batch, and then adjust different opening states of the plurality of test holes 11 by using the plugs 20, so as to change the identification information of the test tray 10; meanwhile, the matching of the sensing elements 31 can meet the identification of the identification information of different test trays 10, so that the operation is convenient, the manufacturing is simple, and the cost is low.

When the sensing element 31 is used to detect the open state of the detection hole 11, it may be used to directly detect whether the detection hole 11 is a through hole or not, or whether the plug 20 is present in the detection hole 11 or not.

Referring to fig. 2 and 3, in some embodiments, the open states of the plurality of detecting holes 11 are determined according to the number of plugs 20 and the arrangement rule of the plurality of plugs 20 relative to the detecting holes 11. Specifically, whether the plug 20 is attached to the detection hole 11 determines the open state of the detection hole 11, that is: the installation plugs 20 are closed holes, and the non-installation plugs 20 are open holes; the combination of the different opening states of the plurality of detection holes 11 corresponds to the identification information of the different test trays 10. Therefore, the number of plugs 20 may determine the number of plugged detection holes 11, and the number of plugs 20 may be different, and the number of plugged detection holes 11 may be different. Meanwhile, when the plugs 20 plug the detection holes 11 at different positions, the combination of the open states of all the detection holes 11 is different, and the detection signals of the corresponding sensing elements 31 are also different. In this manner, identification information corresponding to different test trays 10 is made available.

For example, when the number of the detection holes 11 is 4, 3 of the detection holes 11 may be plugged by the

plugs

20, 2 of the detection holes may be plugged by the plugs 20, or 1 of the detection holes may be plugged by the plugs 20, or even 4 of the detection holes may be plugged by the plugs 20. Moreover, when 3 of the detection holes 11 are plugged, the selection of 3 of the 4 detection holes 11 is also required to be combined. When 2 or 1 detection holes 11 are plugged, a combination selection is also required.

With continued reference to fig. 2 and 3, in a preferred embodiment, the number of plugs 20 is not greater than the number of detection holes 11. With the number of the detection holes 11 being n, the arrangement mode of the plugs 20 relative to the detection holes 11 is 2 ⁿ -2 types of corresponding detection signals of type 2 ⁿ -2. That is, in the present embodiment, whether the plug 20 is present in the detection hole 11 is mainly used as a detection index. Therefore, when the plugs 20 are arranged relative to the detection holes 11, the situation that no plugs 20 are arranged on all the detection holes 11 is eliminated, so that at least one sensing element 31 can detect the plugs 20 to send detection information. Meanwhile, the case that plugs 20 are provided on all the detection holes 11 is excluded. Taking the number of the detection holes 11 as 4 as an example, the 4 detection holes 11 are arranged on the test tray 10 at intervals. The number of plugs 20 is 4, and 4 plugs 20, 3, 2 or 1 plugs 20 may be selected for use.

When the number of the detection holes 11 is 4 and the number of the plugs 20 is 4 or less, the following arrangement and combination forms are provided:

/>

wherein "having" means that the plug 20 is present in the detection hole 11, and "none" means that the plug 20 is absent in the detection hole 11. 2 ⁿ -2＝2 ⁴ -2＝14。

In other embodiments, when the number of plugs 20 is not greater than the number of detection holes 11, the arrangement of plugs 20 relative to detection holes 11 has 2 ⁿ -1, type of corresponding detection signal is 2 ⁿ -1. That is, in this case, only the case where no plugs 20 are provided on all the detection holes 11 is excluded,to ensure that the at least one sensing element 31 is able to detect the plug 20 to send a detection message. Taking n as 4 as an example, the type of the corresponding detection signal is 2 ⁴ -1＝15。

It should be noted that, when only the situation that plugs 20 are provided on all the detection holes 11 is eliminated, the arrangement mode of the plugs 20 relative to the detection holes 11 is 2 ⁿ -1, type of corresponding detection signal is 2 ⁿ -1.

In still other embodiments, when the number of plugs 20 is not greater than the number of detection holes 11, the plugs 20 are arranged in a manner of 2 relative to the detection holes 11 ⁿ The type of the corresponding detection signal is 2 ⁿ A kind of module is assembled in the module and the module is assembled in the module. That is, in this case, when no plugs 20 are provided on all the detection holes 11, identification information of one type of test tray 10 is also corresponding. Taking n as 4 as an example, the type of the corresponding detection signal is 2 ⁴ ＝16。

It should be noted that, since the plugs 20 are only used to plug the detection holes 11, and each plug 20 has the same structure, the arrangement and combination relationship between the plugs 20 is not required to be considered when the plugs 20 are selected in the present embodiment. Therefore, even if the number of plugs 20 is larger than the number of detection holes 11, the arrangement is performed based on the number of detection holes 11 and whether or not the detection holes 11 are plugged by the plugs 20 when the hole-forming state arrangement of the detection holes 11 is performed. Therefore, the number of plugs 20 is the same as the number of detection holes 11 at maximum.

In yet other embodiments, where the plugs 20 are also numbered, a permutation may be required when using the plugs 20, as may be seen with respect to placing m things into n holes. This is a mathematically mature prior art and will not be described in detail.

Referring to fig. 3 and 6, in some embodiments, each of the test holes 11 is provided through the test tray 10 in the thickness direction of the test tray 10. That is, the detection hole 11 is provided as a through hole. At this time, neither contact nor noncontact induction is used, and there is no risk of interference with the detection result due to the influence of the structure of the test tray 10 itself. For example, when a photoelectric switch is used as the sensor 31, it is necessary to determine whether the plug 20 is present or not by determining whether or not a light reflection signal is received. At this time, if the detection hole 11 is a blind hole, the light is reflected by the bottom wall of the detection hole 11, so that it is unclear whether the plug 20 is present in the detection hole 11. However, if the detection hole 11 is a through hole, if the plug 20 is not present, the light beam is not received by the detection hole 11, and if the plug 20 is present, the light beam is reflected to feed back the reflected signal. In addition, the provision of the through holes also facilitates the operator's observation of the presence or absence of the plugs 20.

In some embodiments, the sensing element 31 is triggered by contact with respect to the plug 20, which ensures that the sensing element 31 accurately detects the open state of the detection hole 11. For example, the sensing element 31 is configured to generate a pressure signal responsive to a change in pressure within the sensing bore 11. That is, the sensing element 31 employs a sensor for detecting pressure. At this time, a part of space is reserved at one end of the detection hole 11 for forming a pressure space, and the plug 20 is made of a sealing material, so as to ensure tightness between the plug 20 and the wall of the detection hole 11. For example, the plug 20 is made of a silica gel material or a rubber material.

As a preferred embodiment, the sensing element 31 is a negative pressure sensor. After the plug 20 is installed in the detection hole 11, an air suction disc is assembled at the edge of the detection hole 11 and is connected with a vacuum pump through a conveying pipe so as to suck the gas between the plug 20 and the hole wall to form negative pressure. In other embodiments, the sensing element 31 employs a positive pressure sensor. At this time, a booster pump may be connected to the delivery pipe, and gas may be injected between the plug 20 and the hole wall by the booster pump.

In some embodiments, the sensing element 31 is triggered in a non-contact manner with respect to the plug 20, i.e., the sensing element 31 is a proximity switch. Because the proximity switch needs to be triggered by a certain working distance between the sensing element 31 and the plug 20, when the test tray 10 is assembled relative to the rack 200, it can be ensured that both the test tray 10 and the plug 20 are not in contact with the sensing element 31. By the arrangement, detection is convenient, protection of the sensing element 31 is improved, and service life of the sensing element 31 is prolonged.

In a specific embodiment, the sensing element 31 is configured to generate a magnetic signal in response to the plug 20, i.e., the sensing element 31 employs a hall proximity switch. At this time, the plug 20 is made of a magnetic metal. When the plug 20 approaches the hall proximity switch, the hall element changes the state of the internal circuit due to the hall effect, and thereby recognizes the presence of a magnetic substance nearby, and controls the on/off of the hall proximity switch. When the plug 20 is a conductor, it is necessary to ensure that the chip mounted on the test tray 10 is not interfered with.

In a further embodiment, the sensing element 31 is configured to generate an optical signal in response to the plug 20, i.e. the sensing element 31 employs a photoelectric switch. The photoelectric switch uses the blocking or reflection of the light beam by the plug 20, and the synchronous circuit is used for switching on the circuit, thereby detecting whether the plug 20 exists. In this embodiment, a reflection-selective manner is preferable.

In yet other embodiments, the inductive element 31 is configured to generate an electrical signal in response to the plug 20, i.e., the inductive element 31 employs a capacitive proximity switch. When the test tray 10 is assembled relative to the rack 200, the plug 20 is moved to the capacitive proximity switch, and whether the plug 20 is a conductor or not, the capacitive dielectric constant in the switch changes as long as the plug 20 is close to the capacitive proximity switch, so that the capacitance changes to change the circuit state and generate different electric signals.

Referring to fig. 5 and 6, in some embodiments, the thickness of the plug 20 along the axial direction of the detection hole 11 is not greater than the hole depth of the detection hole 11. Therefore, when the plug 20 is plugged in the detection hole 11, the plug 20 does not protrude in the axial direction of the detection hole 11. Thus, after the test tray 10 moves to the detection station of the sensing element 31, the plug 20 is located within a safe working distance range without interference with respect to the sensing element 31. At the same time, such an arrangement also reserves the space for detecting the change in air pressure of the detection hole 11 described above.

With continued reference to fig. 3 and 6, in a specific embodiment, the edge of the opening at the end of each detection hole 11 facing away from the sensing element 31 is provided with a recess 12, and the recess 12 is recessed in a direction toward the sensing element 31. The plug 20 is installed in the detection hole 11 and the groove 12, and the bottom of the groove 12 is configured with a fixing hole 13. The tray handling assembly 100 further includes a fixing member, one end of which passes through the plug 20 to be connected to the wall of the fixing hole 13.

Specifically, the groove 12 is arranged at the edge of the orifice of the detection hole 11, so that the assembly area of the plug 20 relative to the detection hole 11 is increased; meanwhile, the fixing piece is used for improving the assembly reliability of the plug 20 relative to the detection hole 11, and the possibility that the plug 20 is separated in the operation process of the test tray 10 is reduced. In a preferred embodiment, the detection hole 11 is a circular hole. At this time, the groove 12 and the detection hole 11 together form an eccentric stepped hole including a waist-shaped hole and a circular hole communicating with the waist-shaped hole. In this embodiment, the plug 20 is an elongated block that fits into the waist-shaped hole, and the thickness of the plug 20 is substantially the same as the depth of the waist-shaped hole. Further, the fixing member adopts a screw, and the wall of the fixing hole 13 is provided with internal threads so as to facilitate threaded connection.

With continued reference to fig. 3 and 6, in actual use, the plug 20 is configured with a mounting hole 21 for the fixture to pass through, and an end of the mounting hole 21 facing away from the sensing element 31 is configured with a receiving groove 22. Specifically, the mounting holes 21 are formed so that the fixing members can pass through, and the mounting holes 21 are threaded holes. Therefore, when the fixing member adopts a screw, the fixing member is in threaded connection with the plug 20 and the test tray 10, and the nut of the screw is accommodated in the accommodating groove 22. By the arrangement, the fixing piece is prevented from protruding out of the test tray 10, flatness of the installation position of the plug 20 is improved, and interference of the fixing piece to other parts is reduced. Of course, pins may be used for the fixing member, as long as the plug 20 is fixed with respect to the test tray 10.

In other embodiments, the hole wall of the detection hole 11 is provided with a fixing table protruding upward, and the fixing table extends in a direction approaching the axis of the detection hole 11. At this time, the tray handling assembly 100 further includes a fixing member, one end of which is connected to the fixing table through the stopper 20. That is, by providing the fixing base, the fitting area of the plug 20 with respect to the detection hole 11 is increased, and the connection reliability is improved by fitting with the fixing member. Moreover, because of the fixing table, the installation depth of the plug 20 relative to the detection hole 11 can be limited, so as to ensure that the plug 20 is in a working distance range relative to the sensing element 31.

Of course, the fixing table may be disposed in the axial middle of the detection hole 11, the plug 20 is made of a flexible material, and a clamping groove for clamping the fixing table is configured in the middle of the plug 20, so that the assembly reliability of the plug 20 is further improved.

Referring to fig. 1-4, in some embodiments, the sensing assembly 30 further includes a mounting substrate 32 and a plurality of mounting arms 33 spaced apart from the mounting substrate 32, and each mounting arm 33 is configured to connect to one sensing element 31. That is, by the arrangement of the plurality of mounting arms 33, it is convenient to individually mount and replace each of the sensing elements 31, while the plurality of sensing elements 31 are modularized to be integrally mounted with respect to the housing 200 in cooperation with the arrangement of the mounting substrate 32. Furthermore, the mounting arm 33 is arranged such that the sensing element 31 has a certain mounting height with respect to the frame 200 to satisfy the working distance between the sensing element 31 and the plug 20.

With continued reference to fig. 2 and 3, in a specific embodiment, each of the mounting arms 33 has a first folding arm portion 331, a second folding arm portion 332, and a third folding arm portion 333, where the first folding arm portion 331 and the second folding arm portion 332 are spaced apart along the thickness direction of the test tray 10, the third folding arm portion 333 is connected between the first folding arm portion 331 and the second folding arm portion 332, and the first folding arm portion 331 is used for mounting the sensing element 31, and the second folding arm portion 332 is used for connecting to the mounting substrate 32.

Specifically, the first folding arm portion 331, the third folding arm portion 333 and the second folding arm portion 332 are sequentially enclosed in a U-shape or a Z-shape, and the first folding arm portion 331 has a certain mounting height compared with the frame 200, so as to facilitate the assembly and disassembly of the sensing element 31 relative to the assembly arm 33 when the sensing element 31 is separated from the frame 200. Moreover, because of this arrangement, the sensing element 31 has a mounting height relative to the rack 200 to accommodate the mounting height of the test tray 10 relative to the rack 200, meeting the sensing requirements of the plug 20.

With continued reference to fig. 2 and 3, further, the first folding arm 331 and the second folding arm 332 extend in opposite directions from the connection with the third folding arm 333. The arrangement is such that the first folding arm 331, the third folding arm 333 and the second folding arm 332 enclose a zigzag shape in sequence, reducing interference between the assembly of the sensing element 31 with respect to the first folding arm 331 and the assembly of the mounting base with respect to the frame 200. Meanwhile, the arrangement is such that no other structure except the frame 200 is arranged below the first folding arm 331, which is equivalent to reserving an installation space for wiring the wire end on the sensing element 31, so that the assembly interference of the sensing element 31 is reduced.

With continued reference to fig. 2 and 3, the mounting substrate 32 is further configured with a first elongated hole 321, and the second folding arm 332 is configured with a second elongated hole 3321. Specifically, the elongated holes are provided to provide a margin for mounting so as to fine-tune the mounting position of the mounting substrate 32 with respect to the frame 200, and the mounting position of the mounting arm 33 with respect to the mounting substrate 32. The first locking post for fixing the mounting substrate 32 can move in the first elongated hole 321 along the length direction of the first elongated hole 321, and change the mounting position to adapt to the test tray 10 with different widths. The second locking post for fixing the second folding arm 332 can move in the second elongated hole 3321 along the length direction of the second elongated hole 3321 so as to adapt to the detection holes 11 with different pitches.
