Abstract
Description
Technical Field
[0001] This invention relates to the field of semiconductors, and in particular to a DBC packaging and testing device. Background Technology
[0002] In the existing technology, the DBC packaging and testing process is generally divided into two major steps: first, room temperature static testing, and then high temperature dynamic testing. These two steps operate independently and do not interfere with each other. During the testing process, the DBC substrate that has completed the room temperature static testing needs to be manually transferred to the high temperature dynamic testing. Therefore, most of the current DBC packaging and testing lines are semi-automated operations.
[0003] With industry development and increased market demand for production capacity, how to simplify processes, improve testing efficiency, and at the same time not affect the accuracy of testing results has become a key focus for major companies. Summary of the Invention
[0004] The main objective of this invention is to propose a DBC packaging test device, which aims to solve the problem that existing DBC packaging test lines are manual or semi-automated operations with low testing efficiency.
[0005] To address the above problems, this invention proposes a DBC packaging test device, comprising a static test device and several dynamic test devices connected in series.
[0006] Both the static and dynamic testing equipment include conveyor line one, a three-axis robot, conveyor line three, and a rotary testing platform.
[0007] The static testing equipment also includes a static testing machine and a basket feeding mechanism. The first conveyor line and the basket feeding mechanism convey DBC substrates to the third conveyor line. The three-axis robot grabs the DBC substrates on the third conveyor line and sends them to the rotary testing platform. The rotary testing platform sends the DBC substrates into the static testing machine for room temperature static testing. After the test, the rotary testing platform sends the DBC substrates away from the static testing machine. Then, the three-axis robot sends the DBC substrates on the rotary testing platform back to the third conveyor line. Finally, the third conveyor line sends the DBC substrates to the first conveyor line of the downstream adjacent dynamic testing equipment.
[0008] The dynamic testing equipment also includes a dynamic testing machine. Conveyor line one of the dynamic testing equipment sends the DBC substrate to conveyor line three. A three-axis robot grips the DBC substrate on conveyor line three and sends it to the rotary testing platform. The rotary testing platform feeds the DBC substrate into the dynamic testing machine for high-temperature dynamic testing. After the test, the rotary testing platform removes the DBC substrate from the dynamic testing machine. Then, the three-axis robot returns the DBC substrate from the rotary testing platform to conveyor line three. Finally, conveyor line three sends the DBC substrate to conveyor line one of the adjacent downstream dynamic testing equipment.
[0009] In one embodiment, the dynamic testing equipment includes a second dynamic testing equipment and a plurality of interconnected first dynamic testing equipments, with the upstream of the plurality of interconnected first dynamic testing equipments connected in series with a static testing equipment and the downstream of the first dynamic testing equipment connected in series with the second dynamic testing equipment.
[0010] In one embodiment, both the dynamic testing device one and the dynamic testing device two have two conveyor lines three, which are parallel to each other;
[0011] The conveyor lines of the static and dynamic testing equipment can slide along their own width.
[0012] In one embodiment, the dynamic testing device 2 further includes a conveyor line 4 and a basket receiving mechanism. One of the conveyor lines 3 of the dynamic testing device 2 can convey DBC drawers to the conveyor line 4, and the other conveyor line 3 of the dynamic testing device 2 can convey DBC drawers to the basket receiving mechanism.
[0013] In one embodiment, the DBC packaging and testing equipment further includes a chassis, and the first conveyor line, the three-axis robot, the third conveyor line, the fourth conveyor line, the rotary testing platform, the basket feeding mechanism, and the basket receiving mechanism are mounted on the chassis;
[0014] The chassis is equipped with a slide groove for the three conveyor lines to slide along and a push-pull device for driving the three conveyor lines to slide along the slide groove.
[0015] In one embodiment, the basket feeding mechanism and the basket receiving mechanism have the same structure, both including a material transfer device and a basket;
[0016] The basket has a frame two and a conveyor line two disposed on the frame two. A plate frame is placed on the conveyor line two, and the plate frame can be stacked to hold multiple layers of DBC drawer boards.
[0017] The material transfer device has a frame and a lifting device on the frame. The lifting device is connected to a push-pull device, which is connected to the lifting device. The upper and lower ends of the lifting device are equipped with clamps. A pair of clamps move closer to each other and clamp the frame under the action of the lifting device. The push-pull device is used to move the pair of clamps closer to or away from the basket.
[0018] In one embodiment, the basket feeding mechanism further includes a thrust device connected to a frame. This device is used to move the DBC drawer on the plate holder, which is gripped by a pair of clamps, onto the conveyor line.
[0019] In one embodiment, the three-axis manipulator includes an X-axis translation device and a Y-axis translation device disposed on the X-axis translation device. The Y-axis translation device is provided with a Z-axis lifting device, and the Z-axis lifting device is provided with a push-pull device three. The push-pull device three is connected to a pair of grippers. The push-pull device three drives the pair of grippers to move closer or further apart to grip or release the DBC substrate.
[0020] In one embodiment, the DBC packaging test equipment further includes a barcode scanning device for scanning the DBC substrate on the conveyor line.
[0021] In one embodiment, the rotating test platform includes a rotating device, a lifting device, and a placement plate. The middle part of the placement plate is connected to the rotating device, and the rotating device drives the placement plate to rotate around a vertical axis.
[0022] The DBC substrate is placed at both ends of the placement plate;
[0023] The lifting device is located below one end of the placement plate and is used to lift the DBC substrate on the placement plate for packaging testing.
[0024] Beneficial effects: The DBC packaging test equipment of this invention combines room temperature static testing and high temperature dynamic testing into one, which simplifies the test line architecture, reduces the test line cost, reduces the test line footprint, optimizes the testing process, realizes fully automatic testing operations without manual assistance, and improves testing efficiency and product yield.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0048] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0049] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0050] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
[0051] This invention proposes a DBC packaging test device.
[0052] In a specific embodiment of the invention, such as Figure 1 and Figure 4 As shown, the DBC packaging test equipment includes a static test device 91 and several dynamic test devices connected in series. Further, the dynamic test device includes a second dynamic test device 102 and multiple first dynamic test devices 101 connected in series, for example... Figure 1 and Figure 4 This diagram shows two dynamic testing devices 101 and one dynamic testing device 102. Multiple interconnected dynamic testing devices 101 are connected in series, with the upstream of the static testing device 91 connected in series and the downstream of the dynamic testing device 102 connected in series. The upstream and downstream refer to the directions of the DBC panel extraction and inspection process. Figure 1 and Figure 4 In general, the DBC sample first enters the static testing equipment 91 for room temperature static testing, and then enters the dynamic testing equipment for high-temperature dynamic testing. Multiple dynamic testing equipment can independently perform high-temperature dynamic testing. For example, when one DBC sample enters one of the dynamic testing equipment 101 for high-temperature dynamic testing, another DBC sample can enter another dynamic testing equipment 101 for high-temperature dynamic testing, and a third DBC sample can enter dynamic testing equipment 102 for high-temperature dynamic testing. Figure 1 and Figure 4 The diagram illustrates how three dynamic testing devices work in conjunction with one static testing device 91 to complete the DBC packaging test. The DBC board that has completed the high-temperature dynamic test does not need to enter other dynamic testing devices for a second high-temperature dynamic test; it can directly leave the DBC packaging test device of this invention. This design of the DBC packaging test device results in a high degree of automation and high testing efficiency.
[0053] Furthermore, such as Figure 1 and Figure 4 As shown, the DBC packaging test equipment also includes a chassis 1, and the static test equipment 91 and the dynamic test equipment are mounted on the chassis 1.
[0054] Specifically, such as Figures 5-7 As shown, the static testing equipment 91 includes a static testing machine 9 and a conveyor line 2, a three-axis robot 5, a three-axis conveyor line 6, a rotary testing platform 8, and a basket feeding mechanism installed on the chassis 1. The conveyor line 2, the three-axis robot 5, the three-axis conveyor line 6, the rotary testing platform 8, and the basket feeding mechanism will be described in detail below.
[0055] In this embodiment, as Figures 5-7As shown, both conveyor line 2 and conveyor line 6 are belt conveyors used to transport DBC drawers. Each DBC drawer includes a drawer body 44 and several DBC substrates 45 disposed on the drawer body 44. The drawer body 44 is used to place the DBC substrates 45, for example... Figures 5-7 Three DBC substrates 45 are placed on a pull-out body 44 shown.
[0056] In this embodiment, as Figures 5-7 As shown, the basket feeding mechanism includes a transfer device 3 and a basket 4. The basket 4 is used to store a large number of DBC drawers, and the transfer device 3 is used to pick up the DBC drawers stored on the basket 4.
[0057] In this embodiment, as Figures 5-7 As shown, the basket 4 has a second frame 43 and a second conveyor line 41 mounted on the second frame 43. The second frame 43 is fixedly connected to the housing 1. The structure of the second conveyor line 41 is the same as that of the first conveyor line 2 and the third conveyor line 6, all of which are belt conveyors. Multiple trays 42 are placed on the second conveyor line 41. The trays 42 are moved towards the transfer device 3 by the second conveyor line 41, making it convenient for the transfer device 3 to clamp the trays 42. Preferably, the second frame 43 is provided with multiple second conveyor lines 41 to accommodate more trays 42, and the multiple second conveyor lines 41 are arranged in a straight line from top to bottom, for example... Figures 5-7 The frame 43 shown is equipped with two upper and lower conveyor lines 41. Each layer of conveyor line 41 holds multiple tray racks 42. This design allows the basket 4 to store a large number of DBC trays.
[0058] In this embodiment, as Figures 5-7 As shown, multiple layers of DBC drawers can be stacked on a shelf 42, and adjacent layers of DBC drawers do not touch. This design allows the basket 4 to store a large number of DBC drawers.
[0059] In this embodiment, as Figures 5-7 As shown, the material transfer device 3 has a frame 31 and a lifting device 32 mounted on the frame 31. The frame 31 is fixedly connected to the housing 1. The lifting device 32 is connected to a push-pull device 33, which moves up and down. The push-pull device 33 is connected to a lifting device 34, which moves closer to or away from the basket 4. The lifting device 34 has clamping plates 35 at both its upper and lower ends. The clamping plates 35 move closer to each other and clamp the frame 42 under the action of the lifting device 34. The push-pull device 33 is used to move the clamping plates 35 closer to or away from the basket 4. Figures 5-7As shown, when a pair of clamping plates 35 are needed to clamp a DBC drawer of a certain height, firstly, the lifting device 1 32 is controlled to adjust the height of the pair of clamping plates 35 to fit the DBC drawer of a certain height. Then, the pushing and pulling device 2 33 pushes the pair of clamping plates 35 to the top and bottom of the DBC drawer of a certain height. Finally, the lifting device 2 34 moves the pair of clamping plates 35 closer together to clamp the DBC drawer of a certain height. Figures 5-7 As shown, a thrust device 36 is fixedly installed on the frame 31. After a pair of clamping plates 35 clamp a DBC drawer of a certain height, the lifting device 32 and the push-pull device 33 are controlled to move the DBC drawer between the thrust device 36 and the conveyor line 6. Then, the clamping force of the pair of clamping plates 35 is slightly loosened, and the thrust device 36 is controlled to push the DBC drawer away from the pair of clamping plates 35 and onto the conveyor line 6, thus completing the feeding of the DBC drawer.
[0060] Of course, the feeding of the DBC drawing plate can also be completed through conveyor line 2. Specifically, for example... Figures 5-7 As shown, the chassis 1 is provided with a slide groove 11, and a slide rail 12 is installed in the slide groove 11. The conveyor line 6 is located in the slide groove 11 and can slide along the slide rail 12 in the direction of its own width. The slide groove 11 is also provided with a push-pull device 13 that drives the conveyor line 6 to slide along the slide groove 11. When the push-pull device 13 moves the conveyor line 6 to a position flush with and connected to the conveyor line 2, the conveyor line 2 can transport the DBC drawer plate on it to the conveyor line 6. When the push-pull device 13 moves the conveyor line 6 to the front of the thrust device 36, the thrust device 36 is controlled to push the DBC drawer plate away from a pair of clamps 35 and onto the conveyor line 6. Both methods can realize the feeding of the DBC drawer plate. Figure 6 and Figure 7 The conveyor line 36 shown is located directly in front of the thrust device 36.
[0061] In this embodiment, another purpose of setting up conveyor line 2 is to facilitate the connection between static testing equipment 91 and other testing equipment, so that the DBC trays sent by other testing equipment can smoothly enter the static testing equipment 91 of this embodiment via conveyor line 2 for room temperature static testing.
[0062] In this embodiment, the push-pull device 13, the lifting device 32, the push-pull device 2 33, the lifting device 2 34, and the thrust device 36 are cylinders, hydraulic cylinders, or linear motors.
[0063] In this embodiment, as Figures 5-7As shown, the three-axis robot 5 includes an X-axis translation device 51 and a Y-axis translation device 52 mounted on the X-axis translation device 51. The X-axis translation device 51 is fixedly connected to the chassis 1. The X-axis translation device 51 drives the Y-axis translation device 52 to translate along the X-axis. The Y-axis translation device 52 is equipped with a Z-axis lifting device 53. The Y-axis translation device 52 drives the Z-axis lifting device 53 to translate along the Y-axis. The Z-axis lifting device 53 is equipped with a push-pull device 54. The Z-axis lifting device 53 drives the push-pull device 54 to move up and down along the Z-axis. The push-pull device 54 is connected to a pair of grippers 55. The push-pull device 54 drives the pair of grippers 55 to move closer or further apart to grip or release the DBC substrate 45.
[0064] In this embodiment, the X-axis translation device 51, Y-axis translation device 52, Z-axis lifting device 53, and push-pull device 54 are cylinders, hydraulic cylinders, or linear motors.
[0065] In this embodiment, as Figures 5-7 As shown, the rotating test platform 8 includes a rotating device 81, a lifting device 83, and a placement plate 82. The rotating device 81 and the lifting device 83 are vertically fixed in the housing 1. The middle part of the placement plate 82 is connected to the rotating device 81, and the rotating device 81 drives the placement plate 82 to rotate around a vertical axis. The DBC substrate 45 on the DBC drawer on the conveyor line 6 can be gripped by the three-axis robot 5 and placed at both ends of the placement plate 82. The lifting device 83 is located below one end of the placement plate 82. When that end of the placement plate 82 rotates between the lifting device 83 and the test probe of the static tester 9, the lifting device 83 is controlled to lift the DBC substrate 45 on the placement plate 82, so that the DBC substrate 45 rises and contacts the test probe for room temperature static testing. In actual operation, the placement plate 82 is positioned below the DBC substrate 45 on the placement plate 82. The placement plate 82 stops rotating for a period of time after rotating 180 degrees. This design serves two purposes: firstly, it allows the DBC substrate 45 at one end of the placement plate 82 to undergo room temperature static testing; secondly, the three-axis robot arm 5 picks up the next DBC substrate 45 to be tested and places it at the other end of the placement plate 82. After the previous DBC substrate 45 has completed its room temperature static test, the placement plate 82 rotates another 180 degrees to immediately begin the room temperature static test of the next DBC substrate 45. At the same time, the three-axis robot arm 5 picks up the tested DBC substrate 45 and places it back onto the DBC tray on the conveyor line 6, and then places the next DBC substrate 45 to be tested onto one end of the placement plate 82 again. This achieves fully automated and continuous room temperature static testing without manual assistance, significantly improving testing efficiency and product yield.
[0066] In this embodiment, the rotating device 81 and the lifting device 83 are cylinders, hydraulic cylinders, or linear motors.
[0067] In this embodiment, as Figures 5-7 As shown, the static testing equipment 91 also includes a tray 14, which is placed on the chassis 1. The DBC substrate 45 that passes the test is placed back onto the DBC tray on the conveyor line 6 by the three-axis robot 5, waiting to be sent to the dynamic testing equipment for high-temperature dynamic testing. The DBC substrate 45 that fails the test is placed onto the tray 14 by the three-axis robot 5.
[0068] In this embodiment, as Figures 5-7 As shown, the static testing equipment 91 also includes a barcode scanning device 61, which is used to scan the DBC substrate 45 on the conveyor line 6. The scanning result is transmitted to the static testing machine 9, and the static testing machine 9 automatically runs the room temperature static testing program according to the scanning result to complete the room temperature static testing operation.
[0069] In this embodiment, as Figures 8-10 As shown, the dynamic testing equipment 101 includes a conveyor line 2, a three-axis robot 5, a third conveyor line 6, a barcode scanner 61, a tray 14, and a rotating testing platform 8. The structures of the conveyor line 2, the three-axis robot 5, the third conveyor line 6, the barcode scanner 61, the tray 14, and the rotating testing platform 8 are the same as the corresponding components in the static testing equipment 91, and will not be described in detail here. The following is a detailed introduction to the function and operation of each component in the dynamic testing equipment 101.
[0070] exist Figures 8-10 In this process, one end of the conveyor line 2 extends into the static testing equipment 91, such as... Figure 1 and Figure 4 As shown, this design facilitates the transfer of the tested and qualified DBC substrates from conveyor line 6 in static testing equipment 91 to conveyor line 2 in dynamic testing equipment 101, thereby enabling high-temperature dynamic testing of the tested and qualified DBC substrates 45. Figures 8-10 In this process, the other end of the first conveyor line 2 can be connected to the third conveyor line 6 so that the DBC drawer on the first conveyor line 2 can be conveyed to the third conveyor line 6.
[0071] In this embodiment, as Figures 8-10 As shown, the dynamic testing device 101 has two parallel conveyor lines 6, both of which can slide along their width in the chute 11. This design ensures that other DBC trays can pass through the dynamic testing device 101 to the downstream dynamic testing devices 101 and 102 for high-temperature dynamic testing, thus enabling multiple dynamic testing devices to work simultaneously without interference, effectively improving testing efficiency. For example, Figure 9 As shown, one of the two conveyor lines 36 can house a DBC drawer, which can be placed in... Figure 8The dynamic testing equipment 101 shown is used for high-temperature dynamic testing. Another conveyor line 6 is connected to its upstream conveyor line 2 and downstream conveyor line 2. The upstream conveyor line 2 refers to... Figure 9 The conveyor line 2 of the dynamic testing equipment 101 shown in the diagram, the downstream conveyor line 2 refers to the conveyor line 2 of another dynamic testing equipment 101, such as... Figure 1 and Figure 4 As shown, the two dynamic testing devices 101 are connected in series, that is, the upstream dynamic testing device 101's conveyor line 2 (i.e. Figures 8-10 The conveyor line 12 of the downstream dynamic testing equipment 101 receives the DBC trays from the upstream static testing equipment 91, and the conveyor line 2 of the downstream dynamic testing equipment 101 receives the DBC trays from the upstream dynamic testing equipment 101. The movement of one of the conveyor lines 36 of the upstream dynamic testing equipment 101 connects the upstream and downstream conveyor lines 12, allowing subsequent DBC trays on conveyor line 12 to smoothly pass through the upstream dynamic testing equipment 101 and arrive at the downstream dynamic testing equipment 101. This also allows multiple dynamic testing equipment to operate simultaneously, improving testing efficiency. Similarly, the movement of one of the conveyor lines 36 of the downstream dynamic testing equipment 101 connects the conveyor line 12 of the downstream dynamic testing equipment 101 and the conveyor line 12 of the dynamic testing equipment 2102, allowing subsequent DBC trays on conveyor line 12 to smoothly pass through the dynamic testing equipment 101 and arrive at the dynamic testing equipment 2102. This also allows multiple dynamic testing equipment to operate simultaneously, improving testing efficiency.
[0072] In this embodiment, when the dynamic testing equipment 101 is working, the conveyor line 2 sends the DBC substrate to one of the conveyor lines 6. Then, the barcode scanning device 61 scans the DBC substrate 45. After that, the three-axis robot 5 picks up the DBC substrate 45 from the conveyor line 6 and sends it to the rotary testing platform 8. The lifting device 83 lifts the DBC substrate 45 to contact the test probe of the dynamic testing machine 10 for high-temperature dynamic testing. After the test, the qualified DBC substrate 45 is put back into the DBC tray on the conveyor line 6, and the unqualified products are placed in the tray 14.
[0073] In this embodiment, Figure 3 The structure and working principle of the downstream dynamic testing device 101 shown are similar to those of the previous one. Figures 8-10 The upstream dynamic testing device 101 shown is exactly the same. The structure and working principle of the dynamic testing device 102 are described in detail below.
[0074] like Figures 1-4As shown, the dynamic testing equipment 102 includes a first conveyor line 2, a three-axis robot 5, a third conveyor line 6, a barcode scanner 61, a tray 14, a fourth conveyor line 7, a basket receiving mechanism, and a rotating testing platform 8. The structures of the first conveyor line 2, the three-axis robot 5, the third conveyor line 6, the barcode scanner 61, the tray 14, the basket receiving mechanism, and the rotating testing platform 8 are the same as the corresponding components in the static testing equipment 91, and will not be described in detail here. The following is a detailed introduction to the function and operation of each component in the dynamic testing equipment 101.
[0075] like Figure 2 and Figure 3 As shown, one end of the conveyor line 2 of the dynamic testing device 2 102 extends into the downstream dynamic testing device 101. This design facilitates the conveyor line 3 6 in the downstream dynamic testing device 101 to send its DBC drawer plate to the conveyor line 2 of the dynamic testing device 2 102; Figure 2 and Figure 3 As shown, the other end of the first conveyor line 2 can be connected to the third conveyor line 6 so that the DBC drawer on the first conveyor line 2 can be conveyed to the third conveyor line 6.
[0076] In this embodiment, as Figure 2 and Figure 3 As shown, the dynamic testing device 2 102 has two conveyor lines 3 6, which are parallel to each other. Both conveyor lines 3 6 can slide in the slide groove 11 along their own width direction. This design can avoid affecting the passage of other DBC pull plates that have completed high-temperature dynamic testing through the dynamic testing device 2 102, thereby enabling multiple dynamic testing devices to work at the same time without affecting each other, effectively improving testing efficiency.
[0077] In other words, such as Figure 2 As shown, one of the two conveyor lines 3 and 6 can hold a DBC tray that has not undergone high-temperature dynamic testing. This DBC tray can... Figure 2 High-temperature dynamic testing is performed in the dynamic testing equipment 2 102 shown. DBC substrates 45 that pass the test are picked up by the three-axis robot arm 5 and placed back onto the DBC tray on conveyor line 3 6. DBC substrates 45 that fail the test are picked up by the three-axis robot arm 5 and placed into the tray 14. Then, conveyor line 3 6 transports the DBC trays on it to conveyor line 4 7, from where they leave the dynamic testing equipment 2 102 and enter other downstream testing equipment for easy docking. Another conveyor line 3 6 is connected to its upstream conveyor line 1 2 and downstream basket receiving mechanism. The upstream conveyor line 1 2 refers to... Figure 3As shown in the diagram, the DBC trays that have passed the high-temperature dynamic test by the dynamic testing equipment 101 pass through conveyor line 2 of the dynamic testing equipment 102 and another conveyor line 6 to enter the basket receiving mechanism, thus completing the receiving of the DBC trays. The basket feeding mechanism and the basket receiving mechanism have the same structure. Specifically, the material transfer device 3 clamps the DBC trays conveyed by the conveyor line 6 and then puts the DBC trays into the basket 4, thus completing the receiving of the DBC trays. It can be seen that the dynamic testing equipment 102 can independently complete the high-temperature dynamic test and can also collect or transport the qualified DBC trays to the downstream testing equipment without affecting each other, resulting in high working efficiency.
[0078] In this embodiment, when the dynamic testing equipment 102 is working, the conveyor line 2 sends the DBC trays that have not undergone high-temperature dynamic testing to one of the conveyor lines 6. Then, the barcode scanning device 61 scans the DBC substrate 45. After that, the three-axis robot 5 grabs the DBC substrate 45 on the conveyor line 6 and sends it to the rotary testing platform 8. The lifting device 83 lifts the DBC substrate 45 to contact the test probe of the dynamic testing machine 10 for high-temperature dynamic testing. After the test, the qualified DBC substrate 45 is returned to the DBC tray on the conveyor line 6, and the unqualified products are placed in the tray 14. Then, the DBC trays are conveyed by the conveyor line 6 to the conveyor line 7. The qualified DBC trays that have completed the high-temperature dynamic test by the dynamic testing equipment 101 are conveyed to the basket receiving mechanism through another conveyor line to complete the receiving.
[0079] In this embodiment, the DBC packaging test equipment utilizes conveyor lines 1-2 and 3-6 to connect static test equipment 91, dynamic test equipment 1-101, and dynamic test equipment 2-102 into a single test line. This integrates room-temperature static testing and high-temperature dynamic testing, simplifying the test line architecture, reducing production and installation costs, and minimizing the test line's footprint. The design of the two conveyor lines 3-6 allows for independent room-temperature static testing and high-temperature dynamic testing of the static test equipment 91, multiple dynamic test equipment 1-101, and dynamic test equipment 2-102, without mutual interference. This optimizes the testing process, achieves fully automated testing without manual assistance, and improves testing efficiency and product yield. Furthermore, the design of conveyor lines 1-2 and 4-7 allows the DBC packaging test equipment in this embodiment to easily integrate with other production lines.
