Description

A device for high-temperature and room-temperature testing of DBC Technical Field

[0001] This invention relates to the field of IGBT modules, and in particular to a device for high-temperature and room-temperature testing of DBCs. Background Technology

[0002] DBC substrates are an important component of IGBT modules. They are mainly used to provide a packaging base for chip packaging and also have the functions of heat dissipation, conductivity, and insulation. They are widely used in the electronics and power fields.

[0003] Currently, after DBC liners are manufactured, they need to undergo a series of tests to verify whether their performance is up to standard. Only DBC liners that pass the tests can be released for sale.

[0004] Common testing items include high-temperature dynamic and static testing and room-temperature dynamic and static testing of DBC liners. In existing technologies, high-temperature, room-temperature, dynamic and static testing are completely separated, each using a separate testing line. Multiple testing lines occupy a lot of space and have high testing costs. Each testing line has a single function and can only be used for one testing mode.

[0005] Summary of the Invention

[0006] The main objective of this invention is to provide a device for high-temperature and room-temperature testing of DBC, aiming to solve the problems mentioned in the background art.

[0007] To address the aforementioned problems, this invention proposes a device for high-temperature and room-temperature testing of DBC (Digital Curtain Cells), comprising a mounting plate one, a mounting plate two, a feeding module, a heating transfer module, a testing module, and a unloading and sorting module. The feeding module, heating transfer module, testing module, and unloading and sorting module are mounted on mounting plate one and mounting plate two. The heating transfer module picks up the DBC liner from the feeding module and heats it. Then, the heated DBC liner is sent to the testing module, which performs high-temperature dynamic and high-temperature static tests or high-temperature dynamic and room-temperature static tests on the DBC liner. After testing, the testing module sends the DBC liner to the unloading and sorting module, which sorts and unloads the DBC liner.

[0008] In one embodiment, the feeding module includes a conveyor line, a lifting device, a second lifting device, a two-axis translation device, and a barcode scanner.

[0009] The conveyor line is horizontally and fixedly installed on the mounting plate.

[0010] The lifting device 2 and lifting device 1 are respectively located in the middle and at the end of the conveyor line 1. The lifting device 1 and lifting device 2 are fixedly connected to the mounting plate 1. The operation of the lifting device 1 and lifting device 2 can stop the pallet conveyed by the conveyor line 1.

[0011] The two-axis translation device is fixedly connected to the mounting plate. The barcode scanner is located directly above the conveyor line and is connected to the two-axis translation device. The barcode scanner is driven to move horizontally along the X and Y directions by the two-axis translation device.

[0012] After the lifting device 2 stops the pallet, the barcode scanner moves horizontally along the X and Y directions to scan the product information on all the DBC liners placed on the pallet, and the conveyor line 1 conveys the pallet along the X or Y direction.

[0013] In one embodiment, the feeding module further includes a lifting device four, which is located inside the conveyor line one and is fixedly connected to the mounting plate one. When the lifting device one stops the pallet, the lifting device four lifts the pallet and separates it from the conveyor line one.

[0014] In one embodiment, the feeding module further includes a second conveyor line, a third conveyor line, and a third lifting device. The second conveyor line is horizontally arranged and located inside the first conveyor line, and is connected to the third lifting device.

[0015] The third conveyor line is horizontally arranged and located outside the first conveyor line next to the second conveyor line, and is fixedly connected to the first mounting plate. The conveying direction of the third conveyor line is the same as that of the second conveyor line. After the third conveyor line transports the pallet on it to the second conveyor line, the third lifting device drives the second conveyor line to descend and place the pallet on the first conveyor line. Then the pallet is stopped by the second lifting device.

[0016] In one embodiment, the heating transfer module includes: a material transfer mechanism one, a heating device, a material transfer mechanism two, and a horizontal moving device one;

[0017] The material transfer mechanism includes a three-axis translation device and a suction nozzle connected to the three-axis translation device. The three-axis translation device is fixedly connected to the mounting plate. The three-axis translation device drives the suction nozzle to pick up the DBC liner from the tray stopped by the lifting device and then places the DBC liner onto the heating device.

[0018] The heating device is fixedly connected to the mounting plate.

[0019] The second material transfer mechanism is fixedly connected to the first mounting plate, and the second material transfer mechanism and the first material transfer mechanism have the same structure;

[0020] The horizontal moving device 1 is fixedly connected to the mounting plate 1. The horizontal moving device 1 is equipped with a heating seat 1. The material transfer mechanism 2 transfers the DBC liner plate that has been heated on the heating device to the seat 1. The horizontal moving device 1 then transfers the seat 1 to the material pick-up position of the test module.

[0023] The rotating test device 1, rotating test device 2, clamping device 1, clamping device 2, and transfer device are all fixedly connected to the mounting plate 2. The rotating test device 1 and rotating test device 2 have the same structure, and the clamping device 1 and clamping device 2 have the same structure. The high-temperature dynamic test device is located below the rotating test device 1 and clamping device 1, and the static test device is located below the rotating test device 2 and clamping device 2.

[0024] In one embodiment, the rotation testing device includes: a rotation device, a mounting base, a mounting base, a rotation device, a mounting base, a mounting base, a sliding column, a storage base, a pressure plate, and a spring.

[0025] The first mounting base is fixedly connected to the second mounting plate, the second mounting base is rotatably connected to the first mounting base, and the first rotating device is fixedly connected to the first mounting base and is connected to the second mounting base in a transmission manner, which is used to drive the second mounting base to rotate around the vertical axis.

[0026] The third mounting base is rotatably connected to the second mounting base, and the second rotating device is fixedly connected to the second mounting base and is connected to the third mounting base in a transmission manner, which is used to drive the third mounting base to rotate around the horizontal axis.

[0027] The fourth mounting base is fixedly connected to the third mounting base, and the sliding column is vertically slidably connected to the fourth mounting base. The two ends of the sliding column are respectively connected to the second placement base and the pressure plate. The two ends of the spring are connected to the pressure plate and the fourth mounting base. The sliding column causes the spring to be compressed or stretched.

[0028] In one embodiment, the first pressing device includes: a mounting frame, a pressing device, and a pressing column. The mounting frame is fixedly connected to the second mounting plate, the pressing device is fixedly connected to the mounting frame, and the pressing column is connected to the pressing device, thereby driving the pressing column to rise and fall through the pressing device.

[0030] The test head of the high-temperature dynamic testing device is located directly below the pressure column of the first clamping device, and the test head of the static testing device is located directly below the pressure column of the second clamping device.

[0031] In one embodiment, the transfer device includes: a base, a cooling device, a loading tray, and a horizontal moving device.

[0032] The base is fixedly connected to the second mounting plate. The cooling device is located on the base. The loading tray is located on the upper surface of the cooling device and is horizontally slidably connected to the cooling device and the base. The second horizontal moving device is connected to the base and the loading tray and is used to drive the loading tray to move horizontally to contact or separate from the cooling device.

[0033] The material transfer mechanism three moves the DBC liner plate on the first placement seat at the material pick-up position of the test module to the second placement seat of the rotating test device one. Then, the rotating device two drives the second placement seat to rotate 180 degrees. Next, the rotating device one drives the second placement seat to rotate and move to the position directly below the pressure column of the pressing device one. Then, the pressure column descends and pushes the pressure plate to drive the second placement seat to descend so that the DBC liner plate contacts the test head of the high temperature dynamic test device to complete the high temperature dynamic test.

[0034] After the high-temperature dynamic test is completed, the rotating test device 1 drives the DBC liner to reset, and then the transfer mechanism 4 transfers the tested DBC liner on the rotating test device 1 to the loading tray. If the DBC liner on the loading tray needs to be tested at room temperature next, the horizontal moving device 2 drives the loading tray to move horizontally and contact the cooling device to cool the DBC liner on the loading tray.

[0035] The material transfer mechanism five transfers the DBC liner plate on the loading tray to the placement seat two of the rotating testing device two, and then performs a high temperature or room temperature static test. After the test is completed, the rotating testing device two drives the DBC liner plate to reset, and then the material transfer mechanism six removes the DBC liner plate after the high temperature or room temperature static test is completed.

[0036] In one embodiment, the material unloading and sorting module includes: a horizontal moving device 3, a material transfer mechanism 7, a conveyor line 5, a conveyor line 6, a conveyor line 7, an air knife, a conveyor line 8, a conveyor line 9, a lifting device 5, and a lifting device 6;

[0037] The horizontal moving device three is fixedly connected to the mounting plate one. The horizontal moving device three is provided with a placement seat three. The material transfer mechanism six transfers the DBC liner plate that has completed the high temperature or normal temperature static test to the placement seat three. The horizontal moving device three then transfers the placement seat three to the unloading position.

[0038] The material transfer mechanism seven and the material transfer mechanism one have the same structure;

[0039] Conveyor lines five, six, and seven are all fixedly connected to mounting plate one. Conveyor line seven is located above conveyor lines five and six. Conveyor line seven is connected to conveyor line one through conveyor line four. Empty pallets on conveyor line one are transferred to conveyor line seven through conveyor line four.

[0040] The air knife is located above the seventh conveyor line and is fixedly connected to the first mounting plate. It is used to blow air onto the trays on the seventh conveyor line to cool the DBC liner inside the trays.

[0041] The conveyor line 8 is set horizontally and located inside the conveyor line 7, and is connected to the lifting device 5. The lifting device 5 is fixedly connected to the mounting plate 1. The lifting device 5 drives the conveyor line 8 to rise and fall. The conveying direction of the conveyor line 8 is perpendicular to the conveying direction of the conveyor line 7.

[0042] The conveyor line nine is located outside the conveyor line seven next to the conveyor line eight. The conveyor line nine is fixedly connected to the mounting plate one. The conveying direction of the conveyor line nine is the same as that of the conveyor line eight.

[0043] The lifting device 6 is located at the end of the conveyor line 7 and is fixedly connected to the mounting plate 1. The lifting device 6 can stop the pallet on the conveyor line 7, and the conveyor line 8 rises to lift the pallet stopped by the lifting device 6 and separate it from the conveyor line 7.

[0044] The material transfer mechanism 7 transfers the DBC liner plates that fail the test from the placement seat 3 at the unloading position to the conveyor line 5 or the conveyor line 6, and the conveyor line 5 or the conveyor line 6 sends the DBC liner plates that fail the test away for unloading.

[0045] The material transfer mechanism 7 transfers the qualified DBC liner from the storage seat 3 at the unloading position to the tray on the conveyor line 7. After being cooled by the air knife, the qualified DBC liner is sent away by the conveyor line 7 for unloading.

[0046] When it is necessary to conduct random inspections on the qualified DBC liners, first control the lifting device to stop the pallet on the sixth gear on the seventh conveyor line, then lift the pallet on the eighth conveyor line to separate it from the seventh conveyor line, and then the eighth conveyor line will transfer the pallet to the ninth conveyor line for random inspection.

[0047] Beneficial effects: The device for high-temperature and room-temperature testing of DBCs proposed in this application is compatible with a variety of different testing machines, enabling different testing modes for different batches of the same DBC product. It breaks the limitations of the traditional single-support testing method. One testing line can complete different testing modes for different batches of DBC products without the need to set up multiple testing lines, which greatly reduces testing costs and floor space. The testing process is flexible and versatile, fully meeting the needs of various testing procedures for different batches of DBC products. Attached Figure Description

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] This invention proposes a device for high-temperature and room-temperature testing of DBCs. This device is compatible with a variety of different testing machines and can realize different testing modes for different batches of the same DBC product. It breaks the limitations of the traditional single-set testing method. One testing line can complete different testing modes for different batches of DBC products without the need to set up multiple testing lines, which greatly reduces testing costs and floor space. The testing process is flexible and versatile, fully meeting the needs of various testing procedures for different batches of DBC products.

[0077] Specifically, in one embodiment of the invention, as shown in Figure 1, the device for high-temperature and room-temperature testing of DBC includes a mounting plate 1, a mounting plate 2, a feeding module, a heating transfer module, a testing module, and a discharging and sorting module. The feeding module, heating transfer module, testing module, and discharging and sorting module are mounted on the mounting plate 1 and mounting plate 2, respectively. During operation, the heating transfer module picks up the DBC liner from the feeding module and heats it. Then, the heated DBC liner is sent to the testing module, where it performs high-temperature dynamic and high-temperature static tests, or high-temperature dynamic and room-temperature tests, on the DBC liner. After the static temperature test is completed, the testing module sends the DBC liner to the unloading and sorting module, which sorts and unloads the DBC liner. Because the testing module has the functions of high temperature dynamic and high temperature static testing or high temperature dynamic and normal temperature static testing, it realizes different testing modes for different batches of the same DBC product. This breaks the limitations of the traditional single-set testing method. One testing line can complete different testing modes for different batches of DBC products without the need to set up multiple testing lines, which greatly reduces testing costs and floor space. The testing process is flexible and versatile, fully meeting the needs of various testing procedures for different batches of DBC products.

[0078] Specifically, as shown in Figures 2-4, the feeding module includes a conveyor line 2, a lifting device 3, a second lifting device 5, a two-axis translation device 9, and a barcode scanner 10. The conveyor line 2 is horizontally fixed on the mounting plate 1. The second lifting device 5 and the first lifting device 3 are located at the middle and end of the conveyor line 2, respectively. The first lifting device 3 and the second lifting device 5 are fixedly connected to the mounting plate 1. The operation of the first lifting device 3 and the second lifting device 5 can stop the pallet 4 conveyed by the conveyor line 2. Specifically, the pallet 4 conveyed by the conveyor line 2 is first stopped by the second lifting device 5, and then stopped by the first lifting device 3.

[0079] In this embodiment, as shown in Figures 2 and 3, the two-axis translation device 9 is fixedly connected to the mounting plate 1. The barcode scanner 10 is located directly above the conveyor line 2 and connected to the two-axis translation device 9. The two-axis translation device 9 drives the barcode scanner 10 to move horizontally in the X and Y directions. After the lifting device 2 5 stops the tray 4, the barcode scanner 10 moves horizontally in the X and Y directions to scan the product information (such as barcodes, QR codes, etc.) on all the DBC liners placed on the tray 4 for binding of subsequent test data. The conveyor line 2 conveys the tray 4 in the X or Y direction. After all the DBC liners on the tray 4 have been scanned, the lifting device 2 5 resets, and the conveyor line 2 continues to convey the tray 4. Finally, it is stopped by the lifting device 3. Then, the heating transfer module removes the DBC liners from the tray 4. After all the DBC liners are removed, the lifting device 3 resets, and the conveyor line 2 sends the empty tray 4 to the conveyor line 4 30, as shown in Figure 1.

[0080] In this embodiment, as shown in Figures 2-4, the feeding module also includes a lifting device 411. The lifting device 411 is located inside the conveyor line 2 and is fixedly connected to the mounting plate 1. When the lifting device 3 stops the pallet 4, the lifting device 411 lifts the pallet 4 and separates it from the conveyor line 2. With this design, the conveyor line 2 can continue to rotate and feed the pallet 4 while the heating transfer module removes the DBC liner on the pallet 4.

[0081] Furthermore, in this embodiment, as shown in Figures 2-4, the feeding module further includes a second conveyor line 6, a third conveyor line 8, and a third lifting device 7. The second conveyor line 6 is horizontally arranged and located inside the first conveyor line 2, and is connected to the third lifting device 7. The third lifting device 7 is fixedly connected to the first mounting plate 1. The conveying direction of the second conveyor line 6 is perpendicular to the conveying direction of the first conveyor line 2. The third conveyor line 8 is horizontally arranged and located outside the first conveyor line 2 next to the second conveyor line 6, and is fixedly connected to the first mounting plate 1. The conveying direction of the third conveyor line 8 is the same as that of the second conveyor line 6. After the third conveyor line 8 can transport the tray 4 on it to the second conveyor line 6, the third lifting device 7 drives the second conveyor line 6 to descend and place the tray 4 on the first conveyor line 2. Then the tray 4 is stopped by the second lifting device 5. After the second lifting device 5 is reset, the tray 4 is sent away by the first conveyor line 2. The DBC liner that needs to be retested is placed in the various holes 14 on the tray 4, and then the tray 4 is fed from the third conveyor line 8.

[0082] Specifically, as shown in Figures 2-4, the heating transfer module includes: a material transfer mechanism one, a heating device 15, a material transfer mechanism two 16, and a horizontal moving device one 17. The material transfer mechanism one includes a three-axis translation device 12 and a suction nozzle 13 connected to the three-axis translation device 12. The three-axis translation device 12 drives the suction nozzle 13 to move along the XYZ axes. The three-axis translation device 12 is fixedly connected to the mounting plate one 1. The three-axis translation device 12 drives the suction nozzle 13 to pick up the DBC liner from the tray 4 stopped by the lifting device one 3, and then places the DBC liner on the heating device 15 for preheating in preparation for subsequent high-temperature dynamic testing. The heating device 15 is fixedly connected to the mounting plate one 1. The transfer mechanism 2 16 is fixedly connected to the mounting plate 1, and the transfer mechanism 2 16 and the transfer mechanism 1 have the same structure. The horizontal moving device 17 is fixedly connected to the mounting plate 1, and the horizontal moving device 17 is provided with a heating seat 18. The transfer mechanism 2 16 transfers the DBC liner plate heated on the heating device 15 to the seat 18, and the horizontal moving device 17 moves the seat 18 to the material pick-up position of the test module to facilitate the test module to remove the DBC liner plate. The seat 18 is designed with a heating function to ensure the heating state of the DBC liner plate and ensure that the test temperature of the DBC liner plate entering the high-temperature dynamic test meets the standard.

[0083] Specifically, in this embodiment, as shown in Figure 5, the testing module includes: material transfer mechanism three 19, material transfer mechanism four 20, material transfer mechanism five 21, material transfer mechanism six 22, rotation testing device one 23, rotation testing device two 24, clamping device one 25, clamping device two 26, transfer device 27, high temperature dynamic testing device 28, and static testing device 29; material transfer mechanism three 19, material transfer mechanism four 20, material transfer mechanism five 21, and material transfer mechanism six 22 are all fixedly connected to mounting plate one 1, and material transfer mechanism one, material transfer mechanism three 19, material transfer mechanism four 20, material transfer mechanism five 21, and material transfer mechanism six 22 have the same structure.

Specifically, the rotating device 231 of the rotating testing device 23 can drive the base 237 of the rotating testing device 23 to rotate. The rotating device 231 of the rotating testing device 24 can drive the second seat 237 of the rotating testing device 24 to rotate and move directly below the pressure column 253 of the clamping device 26. In addition, the test head of the high temperature dynamic testing device 28 is located directly below the pressure column 253 of the clamping device 25, and the test head of the static testing device 29 is located directly below the pressure column 253 of the clamping device 26. This design can smoothly realize the testing work. The specific testing method will be described in detail later.

[0087] In this embodiment, as shown in Figure 8, the transfer device 27 includes: a base 271, a cooling device 272, a loading tray 273, and a second horizontal moving device 274. The base 271 is fixedly connected to the second mounting plate 40. The cooling device 272 is disposed on the base 271. The loading tray 273 is located on the upper surface of the cooling device 272 and is horizontally slidably connected to the cooling device 272 and the base 271. The second horizontal moving device 274 is connected to the base 271 and the loading tray 273 and is used to drive the loading tray 273 to move horizontally to contact or separate from the cooling device 272 so as to cool the DBC liner on the loading tray 273. Whether cooling is required will be described in detail later.

[0088] In this embodiment, as shown in Figures 5-8, the working process of the test module is as follows: The material transfer mechanism 19 moves the DBC liner on the first seat 18 at the material picking position of the test module to the second seat 237 of the rotating test device 23. Then, the rotating device 234 drives the second seat 237 to rotate 180 degrees, so that the DBC liner on the second seat 237 faces downward and the pressure plate 238 faces upward. Then, the rotating device 231 drives the second seat 237 to rotate and move to directly below the pressure column 253 of the pressing device 25. The angle at which the rotating device 231 drives the second seat 237 to rotate can be determined according to the specific structural design of the rotating test device 23, such as the rotating test device 23 shown in Figure 5. 3. The rotating test device 24 only needs to rotate the rotating device 231 to rotate the second placement seat 237 90 degrees to move it to the position directly below the pressure column 253 of the clamping device 25. Therefore, after the test is completed, the rotating device 231 can rotate the second placement seat 237 90 degrees in the opposite direction to reset it. After the second placement seat 237 rotates and moves to the position directly below the pressure column 253 of the clamping device 25, the pressing device 252 is controlled to push the pressure column 253 down and push the pressure plate 238 to drive the second placement seat 237 down synchronously so that the DBC liner contacts the test head of the high temperature dynamic test device 28 to complete the high temperature dynamic test. In order to further improve the test efficiency, the test head can rise vertically during the process of the pressing device 252 pushing the DBC liner down.

[0089] After the high-temperature dynamic test is completed, the rotating test device 23 drives the DBC liner to reset, and then the transfer mechanism 20 transfers the tested DBC liner on the rotating test device 23 to the loading tray 273. If the DBC liner on the loading tray 273 needs to be tested at room temperature next, the horizontal moving device 274 drives the loading tray 273 to move horizontally and contact the cooling device 272 to cool the DBC liner on the loading tray 273. If the DBC liner on the loading tray 273 needs to be tested at high temperature next, the loading tray 273 shown in Figure 8 does not need to move horizontally.

[0090] The material transfer mechanism 21 transfers the DBC liner on the tray 273 to the placement seat 237 of the rotating test device 24, and then performs a high temperature or room temperature static test. The test action is the same as that of the rotating test device 23 and the clamping device 25. After the test is completed, the rotating test device 24 drives the DBC liner to reset, and then the material transfer mechanism 22 removes the DBC liner after the high temperature or room temperature static test is completed.

[0091] In this embodiment, a vacuum suction cup is provided on the second storage seat 237, which can firmly adsorb and fix the DBC liner onto the second storage seat 237.

[0094] In this embodiment, the working process of the unloading and sorting module is as follows: The material transfer mechanism 33 transfers the DBC liners that failed the test from the placement seat 32 at the unloading position to the conveyor line 34 or the conveyor line 35. The conveyor line 34 or the conveyor line 35 then sends the DBC liners that failed the test away for unloading. Specifically, the appropriate conveyor line can be selected for unloading according to the model of the DBC liners; empty pallet 4 After entering conveyor line 736, the DBC liners are first stopped by lifting device 743. Then, the material transfer mechanism 733 transfers the qualified DBC liners from the unloading position seat 332 to the tray 4 on conveyor line 736. After the tray 4 is full, lifting device 743 resets, and conveyor line 736 sends the tray 4 away.
