Description

Technical Field

[0001] This utility model belongs to the field of IGBT module technology, and in particular relates to an automated positioning and feeding mechanism for IGBT modules. Background Technology

[0002] IGBT modules have become an important component in the field of power electronics. Various IGBT modules are developing towards higher efficiency, higher reliability, higher integration, and lower cost.

[0003] IGBT modules need to be tested individually before leaving the factory. During the testing process, the IGBT modules need to be scanned and identified first, and then placed on the testing line for subsequent identification and testing. In the current technology, most IGBT modules are scanned manually and then placed on the material tray. Manual scanning wastes a lot of time and reduces the smoothness of material flow, thus reducing the testing efficiency of IGBT modules. At the same time, it is difficult to accurately position the IGBT modules and ensure their flatness when placing them on the material tray manually, resulting in insufficient loading accuracy of IGBT modules and affecting subsequent testing. Utility Model Content

[0004] The purpose of this invention is to provide an automated positioning and feeding mechanism for IGBT modules, which aims to solve the technical problem that manual feeding in the prior art leads to poor placement accuracy and flatness of IGBT modules, affecting subsequent testing.

[0005] This utility model is implemented as follows: an automated positioning and feeding mechanism for IGBT modules includes a feeding trolley, a feeding platform, and a substrate. The feeding platform is located on one side of the substrate, and the feeding trolley works in conjunction with the feeding platform. Multiple sets of trays are provided inside the feeding trolley.

[0006] Two sets of parallel support frames for supporting pallets are fixedly installed on the substrate. A feeding screw module is provided inside the support frame and located on the substrate. The feeding screw module drives the pallet gripper to move along the length of the support frame. The pallet gripper is used to hold the pallet. A rotary pneumatic gripper driven by a power component is provided on the substrate for holding the material on the pallet. A barcode scanner for scanning the material is provided on the substrate and located on the moving path of the rotary pneumatic gripper.

[0007] A further technical solution: The loading trolley is equipped with a feeding rack and the bottom of the loading trolley is equipped with multiple sets of rollers that support the feeding rack, and multiple sets of pallets are slidably installed in the feeding rack.

[0008] A further technical solution: The loading platform is equipped with a loading Z-axis servo module for pushing the unloading rack up and down.

[0009] A further technical solution: A feeding X-axis servo module is fixedly installed on the substrate. The feeding X-axis servo module drives the feeding tray to move. The movement trajectory of the feeding tray interferes with the movement trajectory of the rotating pneumatic gripper.

[0010] Further technical solution: The power assembly includes a mounting plate, which is fixedly mounted on the base plate and is provided with a gripping Y-axis servo module, a gripping X-axis servo module and a gripping Z-axis servo module that are used in sequence for driving and cooperating. The gripping Z-axis servo module drives the rotating pneumatic gripper to move.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By setting the placement position of each material on the pallet, the material is positioned on the pallet. Subsequent pallet movement is under controlled conditions, which enables continuous positioning of the pallet and the materials on it. This ensures that the rotary pneumatic gripper can accurately move to the material placement position to pick up the material and place it in the correct position, thereby ensuring the accuracy of the material's position during movement and avoiding errors and deviations that may occur during human operation.

[0013] 2. The material is picked up by a rotating pneumatic gripper and moved along a set route. As the material moves, it is scanned by a barcode scanner. The barcode recognition is achieved during the material transfer process, reducing the need for manual barcode scanning. The rotating pneumatic gripper makes picking up, placing, and rotating the material more stable and smooth, ensuring the stability and accuracy of the material's position during and after the material is placed, which is beneficial for subsequent material processing.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] like Figures 1-2 As shown, this utility model provides an automated positioning and feeding mechanism for IGBT modules, including a feeding trolley 1, a feeding platform 4 and a substrate 17. The feeding platform 4 is located on one side of the substrate 17 and the feeding trolley 1 is used in conjunction with the feeding platform 4. Multiple sets of trays 3 are provided inside the feeding trolley 1.

[0020] Two sets of parallel support frames 6 for supporting trays 3 are fixedly mounted on the substrate 17. A feeding screw module 7 is provided inside the support frame 6 and located on the substrate 17. The feeding screw module 7 drives the tray gripper 8 to move along the length direction of the support frame 6. The tray gripper 8 is used to hold the tray 3. A rotary pneumatic gripper 13 driven by a power component 18 is provided on the substrate 17 for holding the material on the tray 3. A barcode scanner 14 for scanning the material is provided on the substrate 17 and located on the moving path of the rotary pneumatic gripper 13.

[0021] In practical application, multiple sets of materials to be processed are placed at designated positions on pallets 3. Then, the loading trolley 1 is moved to the side of the loading platform 4, docking with it. After docking, multiple pallets 3 are placed into the loading platform 4. At this time, the loading screw module 7 moves the pallet gripper 8 to the position of the pallet 3, clamping it. After clamping, the loading screw module 7 resets the pallet gripper 8, moving the pallet 3 onto the support frame 6. The pallet 3 remains in a fixed position. Then, the power assembly 18 moves the rotary pneumatic gripper 13 to the material placement position and grips it. The rotary pneumatic gripper 13 then moves along a designated route. As the material moves along the route, it passes the location of the barcode scanner 14, which scans the barcode on the material. Finally, the rotary pneumatic gripper 13 moves the material along the designated route. The terminal rotates the material to a suitable angle, and then the rotating pneumatic gripper 13 releases the material to the subsequent transfer equipment. The rotating pneumatic gripper 13 picks up the material and moves it along the set route. As the material moves, it is scanned by the barcode scanner 14. The barcode recognition is achieved during the material transfer process, reducing the manual scanning process. The rotating pneumatic gripper 13 makes picking up, placing, and rotating materials more stable and smooth, ensuring the stability and accuracy of the material's position during the movement and after placement. This is beneficial for subsequent material processing. The placement position of each material is set through the tray 3, realizing the positioning of the material on the tray 3. The subsequent movement of the tray 3 is under controlled conditions, which can continuously position the tray 3 and the materials on it. This ensures that the rotating pneumatic gripper 13 can accurately move to the material's placement position, pick up the material, and place the material in the accurate position, thereby ensuring the accuracy of the material's position during the movement and avoiding errors and deviations that may occur in human operation.

[0022] like Figures 1-2 As shown, this utility model provides an automated positioning and feeding mechanism for IGBT modules. The feeding trolley 1 is equipped with a feeding rack 2, and the bottom of the feeding trolley 1 is equipped with multiple sets of rollers that support the feeding rack 2. Multiple sets of trays 3 are slidably installed in the feeding rack 2.

[0023] Specifically, the loading platform 4 is equipped with a loading Z-axis servo module 5 for pushing the unloading rack 2 up and down.

[0024] In practical application, multiple sets of pallets 3 containing materials are slidably installed in the feeding rack 2. The feeding rack 2 is placed on the rollers in the loading trolley 1 and fixed. When in use, after the loading trolley 1 is docked with the loading platform 4, the fixing of the feeding rack 2 is released, and the feeding rack 2 is pushed to move on the rollers and enter the loading platform 4. The rollers reduce the friction between the feeding rack 2 and the feeding rack 2, increasing the smoothness of the movement of the feeding rack 2. When a set of pallets 3 in the feeding rack 2 is taken out and then placed back in its original position, the loading Z-axis servo module 5 drives the feeding rack 2 to move, thereby moving the adjacent pallets 3 to a position where they can be clamped. Repeating the above steps can remove the materials on multiple sets of pallets 3.

[0025] like Figures 1-2 As shown, this utility model provides an automated positioning and feeding mechanism for IGBT modules. A feeding X-axis servo module 15 is fixedly installed on the substrate 17. The feeding X-axis servo module 15 drives the feeding disk 16 to move. The moving trajectory of the feeding disk 16 interferes with the moving trajectory of the rotating pneumatic gripper 13.

[0026] In practical application, the material scanned by the barcode camera 14 is moved by the rotary pneumatic gripper 13 to a position where the movement trajectory of the unloading tray 16 interferes with the movement trajectory of the rotary pneumatic gripper 13. Then, the rotary pneumatic gripper 13 moves downward under the drive of the power component 18 to place the material on the unloading tray 16. Subsequently, the unloading X-axis servo module 15 drives the unloading tray 16 to move, moving the material on the unloading tray 16 to the next workstation for further processing. After unloading is completed, the unloading tray 16 returns to the position where the movement trajectory of the unloading tray 16 interferes with the movement trajectory of the rotary pneumatic gripper 13, thereby realizing continuous material transfer.

[0027] like Figures 1-2 As shown, this utility model provides an automated positioning and feeding mechanism for IGBT modules. The power assembly 18 includes a mounting plate 9, which is fixedly mounted on a base plate 17. The mounting plate 9 is provided with a gripping Y-axis servo module 10, a gripping X-axis servo module 11, and a gripping Z-axis servo module 12 that are used in sequence for driving and cooperating. The gripping Z-axis servo module 12 drives the rotating pneumatic gripper 13 to move.

[0028] In practical application, this embodiment drives the Y-axis servo module 10 to move the X-axis servo module 11 in the Y-axis direction, drives the Z-axis servo module 12 in the X-axis direction, and drives the rotary pneumatic gripper 13 in the Z-axis direction. This allows the rotary pneumatic gripper 13 to reach any point covered by the Y-axis servo module 10, X-axis servo module 11, and Z-axis servo module 12 within the space. Consequently, the rotary pneumatic gripper 13 can accurately move to the material placement position, grip the material, and place it in the correct location, thus ensuring the accuracy of the material's position during movement and avoiding errors and deviations that may occur during human operation.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
