Description

Technical Field

[0001] The utility model relates to the field of IGBT, in particular to a fully automatic PIN needle shifting device. Background Art

[0002] IGBT (Insulated Gate Bipolar Transistor) is a fully controlled, voltage-driven power semiconductor device composed of a BJT (bipolar junction transistor) and a MOS (insulated gate field-effect transistor). It combines the advantages of a MOSFET's high input impedance and a GTR's low on-state voltage drop. A GTR has a low saturation voltage drop and high current density, but also offers high drive currents. A MOSFET offers low drive power and fast switching speeds, but also a high on-state voltage drop and low current density. The IGBT combines the advantages of both devices, offering low drive power and low saturation voltage drop. It is ideally suited for applications in power conversion systems with DC voltages of 600V and above, such as AC motors, inverters, switching power supplies, lighting circuits, and traction drives.

[0003] The IGBT module is a modular semiconductor product consisting of an IGBT (insulated gate bipolar transistor chip) and a FWD (diode chip) packaged through a specific circuit bridge. The packaged IGBT module is directly used in inverters, UPS uninterruptible power supplies and other equipment.

[0004] The PIN pin is a metal material used to complete the conduction (transmission) of electricity (signals) in the IGBT module.

[0005] With the rapid advancement of automation equipment, customers are placing increasingly high demands on equipment, demanding both multi-functionality and a compact footprint. This is also true for IGBT modules. Currently, the pins of IGBT modules are fixed to the circuit board using soldering and other methods. The reliability of these pins is crucial to the quality of the IGBT module, so post-soldering quality inspection is required to detect any loosely soldered pins.

[0006] Existing quality inspection solutions mostly rely on manual inspection, whereby the PIN pins are moved by human fingers to see if they shake, thereby determining whether the pins are firmly soldered. This quality inspection method is slow and inefficient, and the quality inspection results are greatly affected by human subjective operation differences, which may lead to misjudgment and low quality inspection quality.

[0036] The utility model proposes a fully automatic PIN needle shifting device, which can replace manual work to complete the PIN needle shifting action, and uses the axial force sensor 22 to detect and judge whether the PIN needle welding is reliable during the needle shifting process, and generates corresponding detection data for each PIN needle for review, thereby realizing the binding of test results and PIN needles, eliminating the trouble of manual recording of detection data, and having high detection accuracy, without the problem of being affected by human subjective operation differences, and having excellent quality inspection quality, fast inspection speed, high efficiency and high inspection accuracy.

[0037] Specifically, in one embodiment of the utility model, as Figure 1 As shown, the fully automatic PIN needle shifting equipment includes a chassis 2 and a hood 1 arranged at the upper end of the chassis 2, and the upper surface of the chassis 2 is equipped with a conveyor line 3, a material moving device, a conveyor line three 24, a needle shifting assembly, a conveyor line two 17, a visual inspection device 19, a lifting device 14, an in-place detection device 12, a lifting device two 6, and a transverse movement device 10. The conveyor line 3, the material moving device, the conveyor line three 24, the needle shifting assembly, the conveyor line two 17, the visual inspection device 19, the lifting device 14, the in-place detection device 12, the lifting device two 6, and the transverse movement device 10 are all located on the inner side of the hood 1.

[0038] In this embodiment, if Figure 2-Figure 4 As shown, the conveyor line 13 is used for loading IGBT modules 14 to be tested and unloading IGBT modules 14 that have been tested and qualified.

[0039] In this embodiment, if Figure 2As shown, a lifting device 4 connected to the chassis 2 and an in-place detection device 12 are provided next to the conveyor line 3. A stopper 5 is provided on the upper end of the lifting device 4. The stopper 5 rises to stop the IGBT module 14 on the conveyor line 3. The in-place detection device 12 is used to detect the position of the IGBT module 14 on the conveyor line 3. When the in-place detection device 12 detects the arrival of the IGBT module 14, it sends a detection signal, and accordingly controls the lifting device 4 to lift the stopper 5 to stop the IGBT module 14 on the conveyor line 3 so that the subsequent lifting plate 8 can be lifted.

[0040] In this embodiment, if Figure 2 As shown, a lifting device 2 6 and a transverse moving device 10 connected to the chassis 2 are provided next to the conveyor line 3. A lifting plate 8 is provided on the upper end of the lifting device 2 6. After the block 5 stops the IGBT module 14 on the conveyor line 3, the lifting plate 8 rises to lift the IGBT module 14 and separate it from the conveyor line 3, so that the IGBT module 14 can be placed on the support plate 11 later.

[0041] Furthermore, in order to make the lifting plate 8 rise and fall smoothly, Figure 2 As shown, the lower end of the lifting plate 8 is connected to a guide column 7, and the guide column 7 is vertically arranged and vertically slidably connected to the chassis 2.

[0042] In this embodiment, if Figure 2 As shown, the transverse moving device 10 is installed on the mounting frame 9, and the mounting frame 9 is fixedly connected to the chassis 2. The transverse moving device 10 is connected to the support plate 11. The support plate 11 is moved transversely toward the conveyor line 3 under the drive of the transverse moving device 10, and moves to the bottom of the IGBT module 14. With this design, when the lifting plate 8 is lowered and reset, the IGBT module 14 is placed on the support plate 11. After the lifting plate 8 is lowered and reset, the remaining IGBT modules 14 on the conveyor line 3 can continue to be driven by the conveyor line 3 to pass under the support plate 11 without delaying the loading of the conveyor line 3. The IGBT modules 14 on the support plate 11 are then transferred to the conveyor line 2 17 for needle detection.

[0043] Furthermore, in order to facilitate the conveying of the IGBT module 14 by the conveying line 13, Figure 2 As shown, the IGBT module 14 is placed on the tray 13, and the tray 13 is placed on the conveyor line 3, and the tray 13 moves horizontally through the conveyor line 3.

[0044] In this embodiment, if Figure 3As shown, the material moving device includes a three-axis translation mechanism 15 and an automatic clamp 16 connected to the three-axis translation mechanism 15. The automatic clamp 16 can clamp the IGBT module 14. The three-axis translation mechanism 15 is installed on the chassis 2. The three-axis translation mechanism 15 drives the automatic clamp 16 to move along the XYZ three axes to clamp the IGBT module 14 on the support plate 11.

[0045] In this embodiment, a carrier jig 18 is provided on the conveyor line 2 17, and the carrier jig 18 is used to place the IGBT module 14. After the material moving device clamps the IGBT module 14 on the support plate 11, the IGBT module 14 is placed on the carrier jig 18. The visual inspection device 19 and the needle shifting assembly are located next to the conveyor line 2 17. The conveyor line 2 17 drives the IGBT module 14 to pass through the visual inspection device 19 and the needle shifting assembly in turn to receive visual inspection by the visual inspection device 19 and needle shifting inspection by the needle shifting assembly. The structure of the visual inspection device 19 is as follows Figure 6 As shown, the structure of the conveying line 2 17 is as follows Figure 5 shown.

[0046] In this embodiment, if Figure 2 and Figure 3 As shown, the material transfer device is also used to transfer the IGBT module 14 that fails the pin-shifting test from the carrier jig 18 to the conveyor line three 24 for unloading, and to transfer the IGBT module 14 that passes the pin-shifting test from the carrier jig 18 to the tray 13 of the support plate 11. After the tray 13 is filled with material, the lifting plate 8 drives the tray 13 down to the conveyor line 3, and then the conveyor line 3 sends the unloaded material away.

[0047] In this embodiment, the pin-moving assembly is used to perform pin-moving detection on the PIN pins on the IGBT module 14 conveyed by the conveyor line 13 to determine whether the PIN pins are firmly welded.

[0048] Specifically, such as Figure 4 and Figure 7As shown, the needle shifting assembly includes: a three-axis translation mechanism 20, a transverse movement device 21, an axial force sensor 22, and a needle shifting piece 23. The three-axis translation mechanism 20 is fixedly connected to the chassis 2; the transverse movement device 21 is connected to the three-axis translation mechanism 20, and the transverse movement device 21 is driven to move along the XYZ three axes through the three-axis translation mechanism 20; the axial force sensor 22 is connected to the transverse movement device 21, and the axial force sensor 22 is driven to move horizontally through the transverse movement device 21; the needle shifting piece 23 is connected to the axial force sensor 22, and the needle shifting piece 23 is connected to the axial force sensor 22. It can swing relative to the axial force sensor 22, and then squeeze the axial force sensor 22, so that the axial force sensor 22 detects a pressure, and the needle shifting member 23 descends and can be inserted into the PIN needle. The axial force sensor 22 is used to detect the axial thrust of the needle shifting member 23 on it, that is, the upward pressure of the needle shifting member 23 on it. When the needle shifting member 23 swings, one end of its upper surface in the swinging direction pushes the axial force sensor 22. At this time, the axial force sensor 22 can detect the upward pressure of the needle shifting member 23 on it. Preferably, the axial force sensor 22 is a multi-dimensional force sensor.

[0049] Working principle: The IGBT module 14 to be tested is placed on the tray 13 and then loaded through the conveyor line 3. After the in-place detection device 12 detects the tray 13, the jacking device 4 controls the stopper 5 to lift and stop the tray 13, and then the jacking device 2 6 controls the jacking plate 8 to rise to lift the tray 13 and separate it from the conveyor line 3. Then the transverse movement device 10 controls the support plate 11 to move transversely to the bottom of the tray 13, and then the jacking plate 8 descends and resets, and the tray 13 remains on the support plate 11. After the jacking plate 8 is reset, the other trays 13 on the conveyor line 3 can continue to be transported by the conveyor line 3 without being affected.

[0050] The three-axis translation mechanism 15 drives the automatic gripper 16 to pick up the IGBT module 14 in the tray 13 on the support plate 11, and then places the IGBT module 14 on the carrier jig 18. The conveyor line 2 17 drives the carrier jig 18 to move to the bottom of the visual inspection device 19, as shown in FIG. Figure 7As shown, the visual inspection of the visual inspection device 19 is performed at this position, and then the positions of the carrier fixture 18, the IGBT module 14, and the PIN pins thereon are identified. These position information are transmitted to the controller, and the controller controls the three-axis translation mechanism 20 to adjust the position of the needle-shifting member 23. When the conveyor line 217 drives the carrier fixture 18 to move to the needle-shifting assembly, the three-axis translation mechanism 220 drives the needle-shifting member 23 to descend vertically and insert it on the PIN pin. Then, the three-axis translation mechanism 220 drives the needle-shifting member 23 to move horizontally to shift the PIN pin to generate a thrust on the PIN pin. At this time, the reaction force of the PIN pin on the needle-shifting member 23 causes the needle-shifting member 23 to swing. The axial force sensor 22 detects the upward pressure of the needle member 23 on it, and the axial force sensor 22 transmits the detection data to the processor in real time. Under normal circumstances, the PIN pin is firmly welded. As the displacement of the needle member 23 moves horizontally, the swing amplitude of the needle member 23 increases, and the axial force sensor 22 detects that the upward pressure of the needle member 23 on it is greater. If the PIN pin is not firmly welded and is loose, as the displacement of the needle member 23 moves horizontally, the axial force sensor 22 detects that the upward pressure of the needle member 23 on it is not gradually increasing under normal circumstances. Based on this abnormal detection data, it is possible to accurately identify and judge whether the PIN pin is firmly welded.

[0051] like Figure 4 As shown, the needle setting assembly is provided with a row of multiple needle setting members 23, which can be used for Figure 2 All PIN pins on one side of the IGBT module 14 are tested for pin shifting. After the test of all PIN pins on one side of the IGBT module 14 is completed, the second lateral movement device 21 is controlled to drive the pin shifting member 23 to move to the other side of the IGBT module 14, and then the above action is repeated to perform pin shifting test on all PIN pins on the other side of the IGBT module 14 until the test of the PIN pins on the IGBT module 14 is completed. During the test process, the processor generates corresponding test data for each PIN pin and stores it for review.

[0052] It should be noted that after the pin-moving member 23 is vertically lowered and inserted into the PIN pin, the horizontal displacement of the pin-moving member 23 cannot be too large, otherwise the firmly welded PIN pin will be damaged. The specific displacement amount can be flexibly set according to the actual situation of the PIN pin, as long as it can be judged whether the PIN pin is firmly welded.

[0053] It can be seen that the fully automatic PIN pin moving device of this embodiment can replace manual work to complete the PIN pin moving action, and use the axial force sensor 22 to detect and determine whether the PIN pin welding is firm during the pin moving process, and generate corresponding test data for each PIN pin for review, thereby realizing the binding of test results and PIN pins, eliminating the trouble of manual recording of test data. Compared with manual inspection, the inspection accuracy is high, the quality inspection quality is excellent, there is no problem of being affected by human subjective operation differences, the inspection speed is fast, the efficiency is high, and the inspection accuracy is high.

[0054] After an IGBT module 14 completes the inspection, if all the PIN pins of the IGBT module 14 are qualified, the three-axis translation mechanism 15 drives the automatic clamp 16 to clamp the IGBT module 14 and send it to the tray 13 on the support plate 11; on the contrary, if at least one PIN pin of the IGBT module 14 fails the inspection, the three-axis translation mechanism 15 drives the automatic clamp 16 to clamp the IGBT module 14 and send it to the conveyor line 3 24 for loading and unloading. After the tray 13 is full of IGBT modules 14, the lifting plate 8 rises to lift the tray 13, and then the support plate 11 is reset. The lifting plate 8 drives the tray 13 down to the conveyor line 3, and the conveyor line 3 sends the qualified IGBT module 14 to the unloading.

[0055] Furthermore, in order to improve the detection efficiency, Figure 2-Figure 4 As shown, a plurality of conveyor lines 2 17 can be arranged next to a conveyor line 1 3 , and each conveyor line 2 17 is equipped with a visual inspection device 19 and a needle shifting assembly.
