[0002] Chips, or integrated circuits (ICs), are the core of modern electronic technology. To ensure their performance, reliability, and application stability, comprehensive functional testing is essential. Chip functional testing is designed to verify whether its functions meet design specifications under specific operations and conditions.
[0003] Chip binning means dividing the data from a chip test into several groups according to certain rules, each group represents a "bin", so as to classify the chip more finely. In the chip testing process, there are often some imperfect situations, such as some chips have some minor problems, but they do not affect the performance of the entire chip. If these chips are directly mixed together, it will increase the difficulty of testing and analysis, and binning is to solve this problem.

In this way, the chip can be analyzed and tested more finely to find out the problems or optimize the design. Chip binning is an important part of chip testing, which has an important impact on the quality, performance and stability of the chip.

[0048] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0049] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. The singular forms "a", "said" and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings, and "multiple" generally includes at least two.
[0050] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
[0051] It should be understood that although the terms first, second, third, etc. may be used to describe the embodiments of the present disclosure, they should not be limited to these terms.
[0052] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or device. In the absence of more restrictions, the elements defined by the sentence "comprises a" do not exclude the presence of other identical elements in the product or device including the elements.
[0053] In the related art, during the finished product testing process, due to the limited binning area in the chip sorter (handler), when facing multi-pass bin products, it is necessary to add multiple processes according to the binning restrictions of the chip sorter (handler), which affects the production capacity and increases the risk of mixing. Therefore, it is very necessary to provide a device that can expand the binning of the chip sorter.
[0054] The chip handler is a very important part of the finished product test automation. It sends the DUT to the ATE (automatic test machine) for testing, and sends the tested DUT (Device Under Test) to different Bin Trays. The mainstream chip handlers on the market can be roughly divided into translational and gravity types. Among them, the translational manipulator is the most widely used due to its good versatility, and the material loading and unloading method is the tray form. The test position can test up to 8 chips at the same time. It is already relatively mature in the automation of finished product testing.
[0055] However, the currently used chip sorting machines (handlers) have a small number of reserved binning areas. When the binning requirements of the chip test exceed the binning area reserved by the handler, it is necessary to add a new test process. The new test process requires a new procedure, which requires additional manpower, material resources, financial resources and time, increasing costs and delaying delivery.
[0056] In addition, there is a high possibility that chips from multiple pass bins are mixed. In actual operation, since some binning areas require manual tray replacement, if the operator does not pay attention to the placement of different bins and mixes chips from different bins together, the chips with the risk of mixing need to be retested, further extending the delivery time.
[0057] Therefore, in the chip testing for multiple pass bins, it is necessary to improve production efficiency by reducing the test process and avoid the risk of mixing by reducing manual operations.
[0058] In order to overcome the above-mentioned problems, the present disclosure provides a chip sorting machine bin expansion device, which is configured to cooperate with the chip sorting machine to perform chip bin processing, and the chip sorting machine bin expansion device includes: a tray storage bin, which has a three-dimensional tray bracket, and the three-dimensional tray bracket is configured to store the expanded bin tray. When the chip sorting machine bin expansion device cooperates with the chip sorting machine to perform chip bin processing, the tray storage bin is located above the tray replacement area of the chip sorting machine; a tray transfer bin, which is located on the side of the tray storage bin away from the chip sorting machine, has a tray transfer device, and is configured to transfer trays between the tray replacement area of the chip sorting machine and the tray storage bin; and a support bin, which is located below the tray transfer bin, supporting the tray transfer bin.
[0059] In the present disclosure, a chip sorter bin expansion device is designed to cooperate with a chip sorter. The chip sorter bin expansion device has a tray storage bin for accommodating multiple trays with expanded bins. Trays are transferred between the tray replacement area of the chip sorter and the tray storage bin, and the bin limit of the chip sorter is expanded, so that the chips required for binning can be automatically sent to multiple bin trays. The test process is reduced, production efficiency is improved, manual operation is reduced, and the risk of mixing is avoided.
[0060] The optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
[0061] Figure 1 A schematic diagram of the structure of a chip sorting machine binning expansion device provided in some embodiments of the present disclosure, Figure 2 This is a schematic diagram of the structure of a tray stereoscopic support in a binning expansion device for a chip sorting machine provided in some embodiments of the present disclosure. Figure 3 A schematic diagram of a usage scenario in which the chip sorter binning expansion device provided in some embodiments of the present disclosure cooperates with the chip sorter operation.
[0062] like Figures 1 to 3 As shown, some embodiments of the present disclosure provide a chip sorter binning expansion device 100, which is configured to cooperate with a chip sorter 200 to perform chip binning. The chip sorter binning expansion device 100 includes a tray storage bin 10, a tray transfer bin 20, and a support bin 30.
[0063] The tray storage bin 10 has a tray stereoscopic support 11, and the tray stereoscopic support 11 is configured to store the trays of the expanded bins. When the chip sorter bin expansion device 100 cooperates with the chip sorter 200 to perform chip binning, the tray storage bin 10 is located above the tray replacement area of the chip sorter 200. The orthographic projection of the tray storage bin 10 on the plane where the tray replacement area of the chip sorter 200 is located overlaps with the tray replacement area of the chip sorter 200.
[0064] The tray transfer bin 20 is adjacent to the tray storage bin 10, and is located on the side of the tray storage bin 10 away from the chip sorter 200, and has a tray transfer device 21, which is configured to transfer trays between the tray replacement area of the chip sorter 200 and the tray storage bin 10. In this way, the number of bins of the chip sorter can be expanded.
[0065] The support bin 30 is located below the tray transport bin 20, adjacent to the tray transport bin 20, and supports the tray transport bin 20. Specifically, the support bin 30 integrally supports the tray transport bin 20 and the tray storage bin 10. In some embodiments, the support bin 30 is provided with functional modules such as a power supply module.
[0066] Figure 4 A schematic diagram of the structure of a chip sorting machine provided in some embodiments of the present disclosure, such as Figures 1 to 4 As shown, in some embodiments, the three-dimensional tray support 11 includes M layers of tray storage positions stacked in the vertical direction, each layer of tray storage positions includes N tray storage positions 111 arranged side by side in the horizontal direction, and the tray replacement area of the chip sorter includes N tray automatic replacement positions 201 arranged side by side, wherein M and N are positive integers. In some embodiments, the number of layers M of the tray storage positions is a positive integer greater than or equal to 1, for example, equal to 5. The N tray storage positions 111 correspond one-to-one to the N tray automatic replacement positions 201 arranged side by side, and N is a positive integer greater than or equal to 1, for example, equal to 3.
[0067] In some embodiments, Figures 1 to 4As shown, the N Tray automatic changing positions 201 arranged side by side correspond to the N automatic loading positions 202 of the chip sorting machine 200 respectively, and the N groups of Tray storage positions of the Tray stereoscopic support correspond to the N Tray automatic changing positions 201 arranged side by side respectively, wherein each group of Tray storage positions includes M stacked Tray storage positions. In some embodiments, the chip sorting machine 200 places the detected chips into the corresponding bin tray, and the bin tray is located on the automatic loading position 202. The chip sorting machine 200 places the detected chips into the corresponding bin tray according to the detection results of the chips. Figure 4 As shown, the chip sorter 200 has only three automatic loading positions. If the chip sorter binning expansion device 100 in this case is not used, the overall test process can only bin the chips into three categories. When the chip binning requirement exceeds 3, for example, 5, specifically the first to fifth categories, it is necessary to increase the test process. Specifically, it is necessary to first use the chip sorter 200 to bin the chips into the first category, the second category, and a comprehensive category including the third to fifth categories. Subsequently, the chips in the comprehensive category continue to be binned into the third to fifth categories using the chip sorter 200. In this process, additional manpower, material resources, financial resources and time are required, which increases costs and delays delivery. Manual disc replacement is required between the two test processes. If the operator does not pay attention to the placement of different bins and mixes chips from different bins together, it is necessary to retest the chips with the risk of mixing, which further extends the delivery time.
[0068] The chip sorter binning expansion device 100 provided in the embodiment of the present disclosure is used in conjunction with the chip sorter 200 to implement binning of chips into more than three categories using one testing process. For example, the chips are divided into 15 categories, among which the bin trays corresponding to categories 1 to 3 correspond respectively to the three tray storage positions in the first layer of the tray stereoscopic bracket 11, the bin trays corresponding to categories 4 to 6 correspond respectively to the three tray storage positions in the second layer of the tray stereoscopic bracket 11, the bin trays corresponding to categories 7 to 9 correspond respectively to the three tray storage positions in the third layer of the tray stereoscopic bracket 11, the bin trays corresponding to categories 10 to 12 correspond respectively to the three tray storage positions in the fourth layer of the tray stereoscopic bracket 11, and the bin trays corresponding to categories 13 to 15 correspond respectively to the three tray storage positions in the fifth layer of the tray stereoscopic bracket 11.
[0069] The bin trays corresponding to categories 1, 4, 7, 10, and 13 correspond to the first tray automatic change position and the first automatic loading position in the chip sorting machine 200, the bin trays corresponding to categories 2, 5, 8, 11, and 14 correspond to the second tray automatic change position and the second automatic loading position in the chip sorting machine 200, and the bin trays corresponding to categories 3, 6, 9, 12, and 15 correspond to the third tray automatic change position and the third automatic loading position in the chip sorting machine 200.
[0070] When the chip sorter 200 bins the test chips, it places the tested chips in the bin tray on the automatic loading position 202. Specifically, for example, when the first automatic loading position, the second automatic loading position, and the third automatic loading position are respectively stored with the first category bin tray, the second category bin tray, and the third category bin tray, and the tested chips happen to be classified into the first category, the second category, or the third category, at this time, the chip sorter 200 places the chips on the corresponding first category bin tray, the second category bin tray, or the third category bin tray.
[0071] When the next chip is classified into other categories other than categories 1 to 3 after testing, for example, the nth category, n is any natural number from 4 to 15, then the chip sorting machine bin expansion device 100 cooperates with the chip sorting machine 200 to operate in conjunction, and the nth category bin tray needs to be placed in its corresponding automatic loading position, and the bin tray previously stored in the automatic loading position needs to be transferred to the corresponding tray storage position in the tray stereoscopic bracket 11 through the corresponding tray automatic changing position, and then the next chip is placed in the nth category bin tray.
[0072] For example, when the next chip is classified into other categories other than Category 10 after testing, when the Category 10 bin tray is located in the first Tray storage position in the fourth Tray storage position in the Tray stereoscopic support 11, the chip sorting machine bin expansion device 100 cooperates with the chip sorting machine 200 to operate in conjunction, and the Category 1 bin tray on the first automatic loading position is returned to the first Tray automatic replacement position, and the Tray conveying device 21 picks up the Category 1 bin tray from the first Tray automatic replacement position and transfers it to the first Tray storage position in the first Tray storage position in the Tray stereoscopic support 11, and the Tray conveying device 21 picks up the Category 10 bin tray from the first Tray storage position in the fourth Tray storage position in the Tray stereoscopic support 11 and transfers it to the first Tray automatic replacement position, and then the Category 10 bin tray on the first Tray automatic replacement position is returned to the first Tray automatic replacement position. The tray is transferred to the first automatic loading position, and then the next chip is placed in the 10th bin tray located on the first automatic loading position.
[0073] By combining the chip sorter 200 with the chip sorter binning expansion device 100, the binning limit of the chip sorter can be expanded, and the chips to be binned can be automatically sent to multiple bin trays, thereby reducing the test process, improving production efficiency, reducing manual operations, and avoiding the risk of mixing materials.
[0074] Figure 5 A schematic diagram of the internal structure of a chip sorter provided in some embodiments of the present disclosure. Figure 5 This is a top view. The following is a brief introduction to the structure and working mechanism of the chip sorter.
[0075] like Figure 4 and 5 As shown, the chip sorting machine 200 includes an external interface area 210 and a sorting area 220, wherein the sorting area 220 is covered by a cover. The external interface area 210 includes a tray supply position 2061 for material to be inspected, a first empty tray loading and unloading position 2071, a second empty tray loading and unloading position 2072, and three tray automatic replacement positions 201, which constitute the tray replacement area of the chip sorting machine 200.
[0076] The sorting area 220 includes a material tray loading position 2062, a first empty tray loading position 2081, a second empty tray loading position 2082, an empty tray transfer robot 2031, an input robot 2032, an output robot 2033, a test position assembly 205, an automatic loading position 202, and a manual loading position 204.
[0077] When the chip sorting machine 200 performs binning, the tray carrying the chip to be tested, i.e., the tray, is loaded onto the tray supply position 2061, and is transferred from the tray supply position 2061 to the tray loading position 2062. The input robot 2032 picks up the chip to be tested from the tray on the tray loading position 2062 and transfers it to the test position assembly 205. The test position assembly 205 cooperates with the automatic tester to complete the test of the chip and determine the bin category. The output robot 2033 picks up the chip after the test and puts it into the corresponding bin tray on the automatic loading position 202 to realize the automatic binning of the chip.
[0078] After all the chips on the tray at the tray loading position 2062 are input into the robot arm 2032 and picked up, the empty tray is transferred from the tray loading position 2062 to the first empty tray loading position 2081, and the empty tray transfer robot arm 2031 transfers the empty tray at the first empty tray loading position 2081 to the first empty tray loading and unloading position 2071, to be picked up manually or by a robot arm for other uses.
[0079] When a bin category of the chip sorter 200 and the chip sorter bin expansion device does not have a corresponding tray or the corresponding tray is fully loaded, an empty tray can be placed in the second empty tray loading and unloading position 2072 manually or by a robot arm, and transferred to the second empty tray loading position 2082 by the empty tray transfer robot 2031, and then transferred from the second empty tray loading position 2082 to the corresponding automatic loading position 202 to continue the binning operation.
[0080] The manual loading position 204 is used for manual binning operations and is suitable for manual binning of a small number of chips.
[0081] Figure 6 A schematic diagram of the structure of a tray transfer bin in a bin expansion device for a chip sorting machine provided in some embodiments of the present disclosure. Figure 7 for Figure 6 A schematic diagram of the structure of the tray conveying device in the tray conveying bin, wherein Figure 7 For oneself Figure 6 Schematic diagram of the perspective on the left side of the center.
[0082] like Figures 1 to 7 As shown, the tray conveying device 21 includes a carrying plate 211 , a transverse slide rail 212 , a longitudinal slide rail 213 and a mechanical arm 214 .
[0083] The supporting plate 211 is arranged at the end of the Tray disk transfer bin 20 away from the Tray disk storage bin 10, and the supporting surface of the supporting plate 211 is arranged facing the Tray disk storage bin 10. The supporting surface is a plane and extends along the vertical direction, such as the second direction Y shown in the figure, that is, the supporting surface is a vertically arranged plane.
[0084] The transverse slide rail 212 is arranged on the bearing surface of the bearing plate 211, and extends along a first direction X, such as a horizontal direction. The longitudinal slide rail 213 is slidably arranged on the transverse slide rail 212, and the longitudinal slide rail extends along a second direction Y, such as a vertical direction. The mechanical arm 214 is slidably arranged on the longitudinal slide rail 213, and the mechanical arm can be extended and retracted along a third direction Z, which is a direction perpendicular to the bearing surface of the bearing plate 211, and any two of the first direction X, the second direction Y, and the third direction Z are orthogonal to each other.
[0085] Such a design allows the robot arm 214 to move freely within the plane where the first direction X and the second direction Y are located, and the robot arm 214 is used to transfer the bin trays between the tray storage position 111 of the tray stereoscopic support 11 and the tray automatic replacement position 201 in the tray replacement area of the chip sorting machine 200.
[0086] Figure 8 A schematic diagram of a scene in which a robotic arm picks up a bin tray according to some embodiments of the present disclosure. Fig. 9 A schematic diagram of the structure of a robotic arm provided in some embodiments of the present disclosure.
[0087] like Figures 1 to 9 As shown, the robot arm 214 includes a robot arm 2141 and a robot gripper. One end of the robot arm 2141 is slidably disposed on the longitudinal slide rail 213, extending in a direction perpendicular to the bearing surface of the bearing plate, i.e., a third direction X, and is retractable in a direction perpendicular to the bearing surface of the bearing plate, i.e., a third direction Z. The robot gripper 2142 is disposed at the free end of the robot arm 214 away from the longitudinal slide rail 213, and is configured to pick up the Tray T. When the robot arm 214 picks up the Tray T, the robot arm 214 moves to above the Tray T, and descends close to the Tray T, and uses the robot gripper 2142 to grab the bottom edge of the Tray T. In some embodiments, as Figure 8 As shown, the tray body is provided with array-arranged slots for accommodating chips, such as packaged chips, with the pins of the chip facing the slots, and at least a portion of the entire chip is accommodated in the slots.
[0088] In some embodiments, the mechanical gripper 2142 includes a gripper body 21421 and at least one pair of mechanical claws 21422. The gripper body 21421 is planar and is disposed on the lower surface of the free end of the mechanical arm 2141 away from the longitudinal slide rail. The at least one pair of mechanical claws 21422 are respectively disposed at two opposite sides of the gripper body 21421 away from the mechanical arm 2141. The at least one pair of mechanical claws 21422 are configured to be relatively close to or relatively far away in a direction parallel to the gripper body 21421 to pick up or release the tray. Figure 8 As shown, in some embodiments on one side, the number of mechanical claws 21422 is 2 pairs.
[0089] Some embodiments of the present disclosure provide a chip sorting system, such as Figure 3 As shown, the chip sorting system 1000 includes a chip sorting machine 200 and the chip sorting machine binning expansion device 100 described in the above embodiment. The chip sorting system can expand the binning limit of the chip sorting machine and can automatically send the chips that need to be binned into multiple bin trays. It reduces the test process, improves production efficiency, reduces manual operations, and avoids the risk of mixing.

[0091] S100: After the chip is tested and classified, the output robot arm picks up the chip;
