Abstract
Description
Technical Field
[0001] This utility model belongs to the field of IGBT testing technology, specifically a tooling for automatic docking and testing of IGBT modules. Background Technology
[0002] After the IGBT modules are manufactured, they need to be tested. Testing typically involves providing a test environment to simulate the temperature of the actual operating environment of the IGBT module. Simultaneously, the IGBT module needs to be powered on to simulate actual use, facilitating observation of the product's response. Therefore, testing fixtures are required. Existing testing fixtures are all manual test components, requiring manual pin insertion and wire connections to the main terminals to conduct current. The disadvantages of existing testing fixtures are cumbersome testing conditions, excessive preparation time, a high probability of human error, and unstable testing conditions, thus affecting test results. If testing different product types is required, new fixtures will be needed. Utility Model Content
[0003] To address the aforementioned problems in existing technologies, the purpose of this utility model is to provide a fixture for automatic docking and testing of IGBT modules. The docking of the IGBT module with the fixture and subsequent testing are automated, shortening the overall product testing time and significantly improving docking efficiency and accuracy. The same fixture can be used to test IGBT modules with the same shape but different models or series. For testing IGBT modules with different shapes, only different product positioning frames and fixtures need to be replaced. The temperature regulating block supporting the IGBT module can automatically adjust the temperature, providing a specified temperature range for IGBT module testing.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A fixture for automatic docking and testing of IGBT modules includes a support base and a temperature regulating component mounted on the support base, a product positioning frame, a jig, a jig mounting component, and a jig driving component. The product positioning frame is used to position and support the IGBT module to be tested. The product positioning frame is mounted and supported on the temperature regulating component, the temperature of which is adjustable. The jig is located directly above the product positioning frame and is connected to a testing system. The jig is mounted on the jig mounting component. The jig driving component is connected to and drives the jig mounting component to move up and down, causing the jig to descend to dock with the IGBT module on the product positioning frame to connect the IGBT module to the testing system, or the jig to rise to disengage from the IGBT module on the product positioning frame.
[0006] As a further improvement to the above technical solution:
[0007] The temperature control assembly includes a temperature control block, a heating element, and a cooling element. The heating element provides heat to the temperature control block, raising its temperature. The cooling element absorbs the heat from the temperature control block, lowering its temperature. The product positioning frame is mounted and supported on the temperature control block.
[0008] The upper surface of the temperature regulating block is also provided with at least one thermometer placement slot, in which a temperature detector is placed, and the temperature detector is electrically connected to the test system.
[0009] The heating element includes a heating tube, which is inserted into the temperature regulating block. When the heating tube is powered on, it heats up and the heat from the heating tube is transferred to the temperature regulating block, causing the temperature of the temperature regulating block to rise.
[0010] The cooling unit includes at least one cooling hole on the temperature regulating block for the passage of cooling water.
[0011] The product positioning frame has at least one product placement hole that is a through hole, and the IGBT module is placed in the product placement hole.
[0012] The fixture includes a fixing plate and a probe fixing block and a probe plate mounted on the fixing plate. The fixing plate is detachably mounted on the fixture mounting assembly. The fixing plate is equipped with terminals that interface with the IGBT module. The terminals on the fixing plate are electrically connected to the test system through the probe plate, which is a PCB board.
[0013] The fixing plate is also equipped with a clamping assembly. The clamping assembly is an elastic component. There are multiple clamping assemblies, which are arranged at intervals. One end of the clamping assembly is connected to the fixing plate, and the other end extends downward. When the fixture and the IGBT module are docked, the clamping assembly contacts and clamps the top of the IGBT module.
[0014] The fixture mounting assembly includes a main plate and mounting blocks. The main plate supports the fixture. There are two mounting blocks, each a long strip with an L-shaped cross-section. Each mounting block includes vertical and horizontal plates connected to each other. The two mounting blocks are arranged in parallel with their interior angles facing each other. The vertical plates of the mounting blocks are fixedly connected to the main plate, and the horizontal plates are arranged alternately with the main plate. The fixture is located between the vertical plates of the two mounting blocks and between the horizontal plates of the main plate and the mounting blocks. The fixture is fixed to the main plate and the mounting blocks by fasteners.
[0015] The jig drive assembly includes a motor, a reducer, a lead screw, and a slider. The motor transmits the drive to the lead screw through the reducer, causing the lead screw to rotate. The slider is fixedly mounted on the whole plate, and the lead screw passes through the slider. When the lead screw rotates, it drives the slider to move along the length of the lead screw, thereby raising and lowering the whole plate.
[0016] The beneficial effects of this utility model are:
[0017] (1) The docking of IGBT modules with tooling and the testing after docking are automated, which shortens the overall testing time of the product and greatly improves the efficiency and accuracy of docking. There is no need for manual docking of the terminals on the product and tooling one by one before testing. It is especially suitable for docking and testing of low-voltage IGBT modules.
[0018] (2) The same fixture can be used to test IGBT modules with the same shape but different models or series. For testing IGBT modules with different shapes, you only need to change the different product positioning frame and different fixture. When changing the fixture, just unscrew the fastener and pull out the fixture. It is simple and quick, and the time for product changeover testing is greatly reduced.
[0019] (3) The temperature adjustment block supporting the IGBT module can automatically adjust the temperature and provide a specified temperature range for the testing of the IGBT module. Attached Figure Description

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0027] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0028] An automated docking and testing fixture for IGBT modules, such as Figure 1 As shown, it includes a support base and a temperature regulation component 2 mounted on the support base, a product positioning frame 3, a fixture 4, a fixture mounting component, and a fixture driving component.
[0029] Product positioning frame 3 is used to position and support the IGBT module to be tested (hereinafter referred to as the product). Product positioning frame 3 is mounted and supported on temperature regulating component 2. The temperature of temperature regulating component 2 is adjustable, providing the required ambient temperature for product positioning frame 3 and the product. Fixture 4 is located directly above product positioning frame 3. Fixture 4 is mounted on fixture mounting component. Fixture drive component is connected to and drives fixture mounting component to rise and fall, causing fixture 4 to descend to dock with the product on product positioning frame 3, or fixture 4 to rise to disengage from docking with the product on product positioning frame 3.
[0030] The support base is a frame structure, including an upper plate 11, a base 12, and guide rods 13. The upper plate 11 and the base 12 are arranged in parallel and spaced apart. The base 12 is supported on the ground or a workbench, and the upper plate 11 is located above the base 12. The upper plate 11 and the base 12 are connected by four guide rods 13, which are located on four parallel edges of the same cuboid.
[0031] Temperature regulating component 2 is mounted and supported on base 12, as shown in the image. Figure 2 As shown, it includes a temperature regulating block 21, a heating section, and a cooling section. The temperature regulating block 21 is a metal block with a roughly rectangular shape. The heating section provides heat to the temperature regulating block 21, causing the temperature of the temperature regulating block 21 to rise. The cooling section absorbs the heat from the temperature regulating block 21, causing the temperature of the temperature regulating block 21 to drop.
[0032] The temperature regulating block 21 has multiple holes, including multiple blind holes and at least one cooling hole 23, which are not connected to the blind holes. Preferably, the blind holes are used to house the heating element, and the cooling holes 23 are used to supply cooling water. The heating element includes multiple heating tubes 22, which can be connected to a power source and heat up when energized. The heating tubes 22 can adopt existing products and structures. One heating tube 22 is inserted into each blind hole, and the energization and de-energization of each heating tube 22 can be controlled independently. After the heating tube 22 is energized and heats up, the heat from the heating tube 22 is transferred to the temperature regulating block 21, causing the temperature of the temperature regulating block 21 to rise. The two inlets and outlets of the cooling holes 23 on the temperature regulating block 21 are connected to water pipes, which are connected to a water source via a water pump to supply cooling water to the cooling holes 23 on the temperature regulating block 21. The cooling water enters from one outlet of the cooling hole 23 on the temperature regulating block 21 and exits from the other outlet. When cooling water flows through cooling holes 23, it absorbs heat from temperature regulating block 21 to cool temperature regulating block 21. Cooling holes 23 and the water pipes, water pumps, water sources, etc. connected to them constitute the cooling section.
[0033] The upper surface of the temperature regulating block 21 is also provided with at least one thermometer placement slot 24, in which a temperature detector is placed for measuring the ambient temperature of the product. In this embodiment, the temperature detector is a thermocouple, and the thermocouple wire is glued and fixed with thermally conductive putty. The thermocouple detects the temperature of the temperature regulating block 21.
[0034] The upper surface of the temperature regulating block 21 is also provided with multiple main terminal pads 25 for supporting the main terminals on the product. Because the main terminal probes 44 on the fixture 4 (described below) need to mate with the main terminals on the product, the fixture 4 applies a certain pressure to the main terminals on the product when it is pressed down, ensuring sufficient electrical conductivity. Therefore, the main terminal pads 25 are used to support the main terminals of the product to prevent them from being bent. In this embodiment, the main terminal pads 25 are made of insulating material PEEEK.
[0035] Product positioning frame 3 is a plate-like structure, such as Figure 3 As shown, the product positioning frame 3 has through holes including a limiting frame fixing hole 31, a product placement hole 32, and a positioning hole 33. The limiting frame fixing hole 31 is used to fix the product positioning frame 3 onto the temperature regulating block 21. The product placement hole 32 is used to place the product, and the outline of the product placement hole 32 matches the shape of the product, so that the product can be stably placed in the product placement hole 32. The bottom surface of the IGBT module contacts and is supported on the temperature regulating block 21, and the periphery of the IGBT module contacts the hole wall of the product placement hole 32. The positioning hole 33 is used to position the product positioning frame 3.
[0036] In this embodiment, four limiting frame fixing holes 31 and two product placement holes 32 are provided. The temperature regulating block 21 has corresponding screw holes. Screws pass through the limiting frame fixing holes 31 and are then inserted into the screw holes on the temperature regulating block 21 to fix the product positioning frame 3 onto the temperature regulating block 21. One product is placed in each product placement hole 32. A cylindrical pin passes through the positioning hole 33 and is then inserted into the temperature regulating block 21.
[0037] In this embodiment, three thermometer placement slots 24 are provided, and each thermometer placement slot 24 contains one thermocouple. Two thermocouples are located in two product placement holes 32 respectively, and the third thermocouple is located between two adjacent product placement holes 32.
[0038] Based on the above structure, if two products of the same model but different series have the same appearance and only differ in the auxiliary pins, then the same product positioning frame 3 can be used without replacing it. If the appearances of different models of products differ significantly, then the product positioning frame 3 needs to be replaced.
[0039] Fixture 4 such as Figure 4 and 5 As shown, the fixture includes a fixing plate 41 and a probe fixing block 42, a clamping assembly 43, a probe plate 46, and a probe plate pad 48 mounted on the fixing plate 41. The probe fixing block 42 is fixed with main terminal probes 44 and auxiliary probes 45, with multiple main terminal probes 44 and auxiliary probes 45. The multiple main terminal probes 44 correspond to the main terminals of the product on the product positioning frame 3, and the multiple auxiliary probes 45 correspond to the auxiliary terminals of the product on the product positioning frame 3. When the fixture 4 is connected to the product, the multiple main terminal probes 44 can be inserted into the multiple main terminals of the product on the product positioning frame 3, and the multiple auxiliary probes 45 can be inserted into the multiple auxiliary terminals of the product on the product positioning frame 3.
[0040] The probe board 46 is a custom-designed PCB board with built-in circuitry. It has interfaces for connecting to the main terminal probe 44 and the auxiliary probe 45, respectively. The main terminal probe 44, the auxiliary probe 45, and the probe board 46 are fixedly connected together using soldering, bolts, or other methods. This eliminates the need for wires and copper busbars, simplifying the main circuit.
[0041] In this embodiment, two probe fixing blocks 42 and two probe plates 46 are provided (for clearer display of the structure, ...). Figures 4-6 Only one probe plate 46 is shown in the image. The two probe fixing blocks 42 correspond to the two products on the two product placement holes 32 on the product positioning frame 3, respectively. The two probe plates 46 correspond to the two probe fixing blocks 42, and each probe plate 46 is connected to the main terminal probe 44 and the auxiliary probe 45 on its corresponding probe fixing block 42.
[0042] In this embodiment, the auxiliary probe 45 is a spring needle with a certain amount of compression.
[0043] The probe board 46 is connected to the testing system to transmit product information to the testing system. Other necessary electrical components, such as capacitors and driver boards, are arranged on the probe board 46. The driver board converts low-voltage, low-current logic signals into high-voltage, high-current drive signals to control the conduction and cutoff of the product. The structure and specific principles of the probe board 46 itself are prior art and are not part of the technical content claimed in this solution; therefore, they will not be described further.
[0044] The clamping assembly 43 applies pressure to the product to clamp it onto the product positioning frame 3. Multiple clamping assemblies 43 are elastic components, spaced apart. One end of the elastic component is connected to the fixed plate 41, and the other end extends downwards. When the fixture 4 and the product are aligned, the clamping assembly 43 contacts and clamps the top of the product, ensuring good contact between the product and the temperature regulating block 21 and guaranteeing efficient heat exchange. In this embodiment, the clamping assembly 43 is a disc spring assembly, consisting of a disc spring, a disc spring fixing rod, and a pressure head. The disc spring fixing rod is fixed to the fixed plate 41, and one end of the disc spring is connected to the disc spring fixing rod, while the other end is connected to the pressure head. When the fixture 4 and the product are aligned, the pressure head contacts the top of the product, and under the elastic potential energy of the disc spring, the pressure head clamps the product.
[0045] The probe plate pad 48 is mounted on the fixing plate 41. The probe plate pad 48 extends beyond the edge of the fixing plate 41 to support the part of the probe plate 46 that extends beyond the fixing plate 41, preventing the probe plate 46 from breaking or bending due to excessive force when it is plugged in or unplugged from the probe plate 46 or related electrical components.
[0046] The fixing plate 41 has two through holes 47. After the fastener 7 passes through the fixing holes 47, it fixes the fixing plate 41 to the fixture mounting assembly.
[0047] The fixing plate 41 is also provided with at least one handle 49 to facilitate manual force application to install or remove the fixture 4 from the fixture mounting assembly.
[0048] Fixture mounting components such as Figure 1 and 6As shown, the fixture includes a main plate 51 and mounting blocks 52. The main plate 51 is parallel to the base 12 and supports the fixture 4. Each guide rod 13 passes through the main plate 51 to guide its lifting and lowering. There are two mounting blocks 52, which are elongated and L-shaped in cross-section. The two mounting blocks 52 are arranged parallel to each other and spaced apart, with their inner angles facing each other. The mounting blocks 52 are fixedly mounted on the main plate 51. Specifically, the mounting block 52 includes a vertical plate and a horizontal plate that are integrally connected and perpendicular to each other. The vertical plate of the mounting block 52 is fixedly connected to the main plate 51, and the horizontal plate is spaced apart from the main plate 51. The fixture 4 is located between the vertical plates of the two mounting blocks 52 and between the main plate 51 and the horizontal plate of the mounting block 52. Preferably, the gap between the horizontal plate of the mounting block 52 and the main plate 51 is approximately equal to the thickness of the two ends of the fixing plate 41, so that the fixing plate 41 is supported on the mounting blocks 52. Meanwhile, the length of the mounting block 52 is greater than the dimension of the fixing plate 41 in the same direction, so that when the handle 49 is pulled, the mounting block 52 acts as a guide rail, and the fixture 4 is pulled out along the length direction of the mounting block 52.
[0049] When installing the fixture 4, the fasteners 7 pass through the fixing holes 47 on the main plate 51, the fixing plate 41, and the horizontal plate of the mounting block 52 in sequence, thus fixing the fixture 4 onto the main plate 51. Obviously, in this embodiment, two fasteners 7 are provided.
[0050] In this embodiment, fastener 7 is a knob-type quick-locking device to achieve convenient and quick locking and disassembly. This embodiment uses a knob-type quick-locking device manufactured by Yiheda Company. Figure 5 7' shows a component of a rotary quick-locking device installed in the fixing hole 47.
[0051] The fixture drive assembly includes a motor 61, a reducer 62, a lead screw 63, and a slider. The motor 61 and reducer 62 are supported on the top of the upper plate 11. Two lead screws 63 and two sliders are provided. Two sliders are fixedly mounted on the plate 51, and two lead screws 63 are arranged parallel and spaced apart, located at either end of the length or width of the plate 51. Each lead screw 63 passes through one of the two sliders and is screwed to one of the two sliders. When the lead screw 63 rotates, it drives the slider to move along the length of the lead screw 63, thereby raising and lowering the plate 51. The motor 61 transmits drive to the lead screw 63 through the reducer 62, causing the lead screw 63 to rotate.
[0052] The motor 61, each heating tube 22, each thermocouple, and the water pump are all electrically connected to the test system.
[0053] Based on the above structure, the working principle of this utility model is as follows: The product is placed in the product placement hole 32 of the product positioning frame 3. Each heating element 22 is turned on, and each heating element 22 is energized to heat up and transfer heat to the temperature regulating block 21. When the temperature detected by the thermocouple reaches the first set value, the testing system controls each heating element 22 to be de-energized; when the temperature detected by the thermocouple reaches the second set value, the testing system controls each heating element 22 to be energized again. In this way, the temperature of the temperature regulating block 21 is adjusted to a set range, so that the ambient temperature of the product is within the set range.
[0054] Then, the testing system starts motor 61, which drives the entire plate 51 to descend a set distance via lead screw 63 and slider. This causes the entire plate 51 to lower the fixture 4, so that each main terminal probe 44 on the fixture 4 is connected to each main terminal of the product on the product positioning frame 3, and each auxiliary probe 45 is connected to each auxiliary terminal of the product on the product positioning frame 3. In this way, the product and the probe board 46 are electrically connected, and the probe board 46 sends the product information to the testing system for testing and judgment. After the test is completed, motor 61 drives the entire plate 51 to rise the fixture 4 until the fixture 4 is detached from the product. The heating tubes 22 are de-energized, the water pump is turned on, and cooling water is introduced into the through hole of the temperature regulating block 21 to cool it down.
[0055] When it is necessary to inspect products with different shapes, simply replace the product positioning frame 3 and fixture 4 that match the product being inspected. Specifically, unscrew the fastener 7 to release the fixture 4 from the fixture mounting assembly, grasp the handle 49 and pull out the fixture 4, then insert the new fixture 4, and finally use the fastener 7 to fix the new fixture 4 onto the fixture mounting assembly.
[0056] Finally, it is necessary to state that the above embodiments are only used to further illustrate the technical solution of this utility model in detail, and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made by those skilled in the art based on the above content of this utility model shall fall within the scope of protection of this utility model.
