Description

Technical Field

[0001] The invention belongs to the technical field of IGBT modules, and in particular relates to an IGBT module feeding system. Background Art

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

[0003] The IGBT modules need to be tested one by one before leaving the factory. After the IGBT modules are produced, they will be placed on a pallet. Then, multiple groups of pallets will be placed on a group of unloading racks. The unloading will then be transported by a loading trolley, and the unloading rack will be transported to the loading table. In the prior art, when the unloading rack is placed on the loading trolley, the loading trolley positions the unloading rack through positioning pieces that are in sliding contact with the unloading rack on both sides. Therefore, it is necessary to adjust the positioning pieces of the unloading rack on the loading trolley in advance so that the positions of the positioning pieces and the two sides of the unloading rack coincide with each other. When placing the unloading rack, it is necessary to align the unloading rack with the position defined by the positioning pieces, and then the unloading rack can be pushed and placed on the loading trolley. It takes a lot of time to adjust the alignment of the unloading rack with the positioning pieces, which reduces the loading speed of the IGBT module. In addition, since the positioning pieces are in sliding contact with the side of the unloading rack, the positioning pieces are prone to collide with the unloading rack when aligned and placed. The impact may cause slight changes in the position or placement flatness of the IGBT module, which is not conducive to subsequent detection. Summary of the invention

[0004] The object of the present invention is to provide an IGBT module loading system, aiming to solve the technical problems in the prior art that it is difficult to quickly place a material placing rack on a loading trolley and collision occurs during placement.

[0005] The present invention is implemented as follows: an IGBT module loading system includes a loading trolley, a loading platform and a substrate, the loading platform is located on one side of the substrate and the loading trolley is used in conjunction with the loading platform, a material placing rack is provided in the loading trolley and a plurality of trays are slidably installed in the material placing rack, and an adjustment component for changing the position of the material placing rack is provided on the loading trolley; Two groups of support frames for supporting pallets are fixedly installed on the base plate and are distributed in parallel with each other at intervals. A feeding screw module located on the base plate is arranged in the support frame. The feeding screw module drives the pallet clamp to move along the length direction of the support frame. The pallet clamp is used to clamp the pallet. A rotating pneumatic clamp driven by a power component is arranged on the base plate and is used to clamp the material on the pallet. A code scanning camera for scanning the material is arranged on the base plate and is located on the moving path of the rotating pneumatic clamp.

[0006] Further technical solution: A placing plate is provided on the loading trolley, and the placing plate is installed on the loading trolley through ball bearings. The placing plate is a U-shaped structure and multiple groups of parallel placement shafts for placing the material rack are rotatably installed in the placing plate.

[0007] Further technical solution: The loading trolley is fixedly installed with a first bracket and a second bracket, and two sets of connecting plates are fixedly installed on the first bracket and the second bracket. A limit plate is slidably installed on the connecting plate, and the limit plate is located between the loading trolley and the placement plate. The loading trolley and the placement plate are respectively provided with a placement groove and a limit groove used in conjunction with the limit plate.

[0008] Further technical solution: A loading Z-axis servo module for driving the unloading rack to move up and down is arranged in the loading platform.

[0009] Further technical solution: A material unloading X-axis servo module is fixedly installed on the base plate, and the material unloading X-axis servo module drives the unloading tray to move, and the moving trajectory of the unloading tray interferes with the moving trajectory of the rotating pneumatic clamp.

[0010] Further technical solution: The adjustment component includes a power frame, which is an L-shaped structure and is provided with two groups. The two groups of power frames are respectively slidably installed on the two groups of second brackets. One end of the power frame located in the two groups of second brackets is fixedly installed with a guide plate. The guide plate is an obtuse-angle bending structure and the two groups of guide plates are symmetrically distributed. The guide plate is used in conjunction with a guide cylinder rotatably installed on the discharge rack. The loading trolley is provided with a moving unit for driving the two groups of power frames to move simultaneously.

[0011] Further technical solution: The moving unit includes a screw rod, which is rotatably installed on the loading trolley. Both ends of the screw rod drive a group of moving bars to move. The moving bars are fixedly connected to the power frame on the same side. The screw rod is driven by a worm gear rotatably installed on the loading trolley.

[0012] Further technical solution: the worm and the lead screw are skewed and perpendicular and the worm is meshed with a worm wheel fixedly mounted on the lead screw, a gear is fixedly mounted on one end of the worm away from the lead screw, and the gear is meshed with a rack arranged on the loading trolley.

[0013] Further technical solution: A slide groove is provided on the feeding trolley, a slider is slidably installed in the slide groove, the slider is fixedly connected to the rack and a limit ring is fixedly installed on the slider.

[0014] Further technical solution: The power assembly includes a mounting plate, which is fixedly mounted on the base plate and is provided with a Y-axis servo module, an X-axis servo module and a Z-axis servo module for grabbing materials, which are driven and used in sequence. The Z-axis servo module for grabbing materials drives the rotating pneumatic clamp to move.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When loading, by increasing the distance between the guide plates, the unloading rack can be quickly placed on the placement axis. There is no need to position and align the unloading rack before placing it, which improves the placement speed of the unloading rack and avoids collision when the unloading rack is placed on the loading trolley, ensuring the stable and accurate placement of the IGBT module.

[0016] 2. By reducing the distance between the guide plates, the guide plates apply pressure to the unloading rack to fix it. While pressing and fixing it, the unloading rack is moved to the middle position and positioned in the center, avoiding the cumbersome process caused by separate positioning and fixing, reducing the workload, and facilitating the subsequent direct push of the unloading rack to move.

[0017] 3. When the unloading rack leaves, the distance between the guide plates is set to limit the path of the unloading rack, so as to ensure that the path of the unloading rack moving to the loading platform is the path after accurate positioning, thereby ensuring the accuracy of the unloading rack position.

[0018] 4. The placement position of each material is set by the pallet to achieve the positioning of the material on the pallet. The subsequent movement of the pallet is under controlled conditions, so that the pallet and the material on it can be continuously positioned, ensuring that the rotating pneumatic gripper can accurately move to the placement position of the material to clamp the material and place the material in the correct position, thereby ensuring the accuracy of the position of the material during the movement and avoiding errors and deviations that may occur in human operation.

[0019] 5. The pneumatic gripper is rotated to grip the material and move it along the set route. When the material moves, it passes the position of the barcode scanning camera for barcode scanning and identification. Barcode scanning and identification are realized during the material transfer process, reducing the manual scanning process. The pneumatic gripper is rotated to pick up, place, and rotate the material more stably and smoothly, ensuring the stability and accuracy of the position of the material during the movement and after placement.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0030] like Figure 1-Figure 7 As shown, an IGBT module loading system provided by the present invention comprises a loading trolley 1, a loading platform 4 and a substrate 17, the loading platform 4 is located on one side of the substrate 17 and the loading trolley 1 is used in conjunction with the loading platform 4, a material placing rack 2 is arranged in the loading trolley 1 and a plurality of trays 3 are slidably mounted in the material placing rack 2, and an adjusting component 38 for changing the position of the material placing rack 2 is arranged on the loading trolley 1; Two groups of support frames 6 for supporting the pallet 3 are fixedly installed on the base plate 17 and are distributed in parallel with each other. A feeding screw module 7 located on the base plate 17 is arranged in the support frame 6. The feeding screw module 7 drives the pallet clamp 8 to move along the length direction of the support frame 6. The pallet clamp 8 is used to clamp the pallet 3. A rotating pneumatic clamp 13 driven by a power component 39 is arranged on the base plate 17 for clamping the material on the pallet 3. A barcode scanning camera 14 for scanning the material is arranged on the base plate 17 and is located on the moving path of the rotating pneumatic clamp 13.

[0031] In actual application of this embodiment, multiple groups of materials to be processed are placed at set positions on the tray 3, and then the multiple groups of trays 3 are placed on the material rack 2, and then the material rack 2 is pressed and fixed by the adjusting component 38, and the material rack 2 is centered on the loading trolley 1 while being pressed and fixed, and then the loading trolley 1 is pushed to move to the side of the loading platform 4, so that the loading trolley 1 and the loading platform 4 are docked, and after the docking is completed, the pressing of the material rack 2 by the adjusting component 38 is released, and at the same time, the moving path of the material rack 2 is restricted by the adjusting component 38, and then the material rack 2 can be pushed to enter the loading platform 4; The feeding screw module 7 drives the pallet clamp 8 to move to the position of the pallet 3, and then clamps the pallet 3 through the pallet clamp 8. After clamping is completed, the feeding screw module 7 drives the pallet clamp 8 to reset, so that the pallet 3 moves to the supporting frame 6. At this time, the pallet 3 maintains a fixed position, and then the power component 39 drives the rotating pneumatic clamp 13 to move. The rotating pneumatic clamp 13 moves to the position where the material is placed and clamps the material. Then, the rotating pneumatic clamp 13 moves along the set route. When the material moves driven by the rotating pneumatic clamp 13, it passes the position of the code scanning camera 14. The code on the material is scanned and identified by the code scanning camera 14. Then, the rotating pneumatic clamp 13 drives the material to move to the terminal of the set route and rotates the material to a suitable angle. Then, the rotating pneumatic clamp 13 releases the material to the subsequent transfer equipment. The pneumatic gripper 13 grips the material and moves it along a set route. When the material moves, it passes the position of the barcode scanning camera 14 for barcode scanning and identification. Barcode scanning and identification are realized during the material transfer process, reducing the manual scanning process. The material can be picked up, placed, and rotated more stably and smoothly by rotating the pneumatic gripper 13, ensuring the stability and accuracy of the position during the material movement process, that is, after placement, which is beneficial to the subsequent processing of the material. The placement position of each material is set by the tray 3 to achieve the positioning of the material on the tray 3. The subsequent movement of the tray 3 is under controlled conditions, so that the tray 3 and the material thereon can be continuously positioned, ensuring that the rotating pneumatic gripper 13 can accurately move to the placement position of the material to grip the material and place the material at the correct position, thereby ensuring the accuracy of the position of the material during the movement and avoiding errors and deviations that may occur in human operation.

[0032] like Figure 2 , Figure 4 As shown, an IGBT module loading system provided by the present invention is provided with a placing plate 20 on the loading trolley 1. The placing plate 20 is installed on the loading trolley 1 through ball bearings. The placing plate 20 is a U-shaped structure and a plurality of sets of parallel distributed placing shafts 21 for placing the placing rack 2 are rotatably installed in the placing plate 20.

[0033] Specifically, the loading trolley 1 is fixedly installed with a first bracket 18 and a second bracket 19, and the first bracket 18 and the second bracket 19 are jointly fixedly installed with two groups of connecting plates 22, and a limiting plate 23 is slidably installed on the connecting plate 22, and the limiting plate 23 is located between the loading trolley 1 and the placing plate 20. The loading trolley 1 and the placing plate 20 are respectively provided with a placing groove 24 and a limiting groove 25 used in conjunction with the limiting plate 23.

[0034] In actual application of this embodiment, the material placing rack 2 is placed on the placing shaft 21, and the placing shaft 21 enables the material placing rack 2 to move smoothly. At the same time, under the action of the ball, the placing plate 20 can move freely on the loading trolley 1. When in use, the limit plate 23 is moved upward and fixed by the fixing screw, so that the limit plate 23 enters the limit groove 25. At this time, under the action of the limit plate 23, the placing plate 20 can only move along the limit plate 23, so that the moving direction of the placing plate 20 is limited. When the placing plate 20 needs to be taken out for maintenance, the limit plate 23 is moved downward to make it enter the placing groove 24 and fill the placing groove 24. At this time, the surface of the loading trolley 1 can form a complete plane, and the placing plate 20 can be pushed out from the loading trolley 1.

[0035] like Figure 1 As shown, an IGBT module feeding system provided by the present invention is provided in a feeding platform 4 with a feeding Z-axis servo module 5 for pushing the unloading rack 2 to move up and down.

[0036] In actual application of this embodiment, the material loading Z-axis servo module 5 drives the material unloading rack 2 to move, thereby moving the tray 3 to a position where it can be clamped, and the above steps are repeated to remove the materials on multiple groups of trays 3.

[0037] like Figure 1-Figure 3 As shown, an IGBT module loading system provided by the present invention is provided, wherein a feeding X-axis servo module 15 is fixedly mounted on a substrate 17 , and the feeding X-axis servo module 15 drives a feeding tray 16 to move, and the moving trajectory of the feeding tray 16 interferes with the moving trajectory of the rotating pneumatic clamp 13 .

[0038] In actual application of this embodiment, the material scanned by the barcode scanning camera 14 is moved to the position where the moving trajectory of the discharge tray 16 interferes with the moving trajectory of the rotating pneumatic clamp 13 under the drive of the rotating pneumatic clamp 13, and then the rotating pneumatic clamp 13 moves downward under the drive of the power component 39 to place the material on the discharge tray 16, and the subsequent discharge X-axis servo module 15 drives the discharge tray 16 to move and drives the material on the discharge tray 16 to the next workstation for subsequent processing. After the discharge is completed, the discharge tray 16 returns to the position where the moving trajectory of the discharge tray 16 interferes with the moving trajectory of the rotating pneumatic clamp 13, thereby realizing the continuous transportation of materials.

[0039] like Figure 1-Figure 7 As shown, an IGBT module feeding system provided by the present invention, the adjustment component 38 includes a power frame 31, the power frame 31 is an L-shaped structure and is provided with two groups, the two groups of power frames 31 are respectively slidably installed on the two groups of second brackets 19, one end of the power frame 31 located in the two groups of second brackets 19 is fixedly installed with a guide plate 32, the guide plate 32 is an obtuse-angle bending structure and the two groups of guide plates 32 are symmetrically distributed, the guide plate 32 is used in conjunction with a guide cylinder 37 rotatably installed on the discharge rack 2, and the loading trolley 1 is provided with a moving unit 40 for driving the two groups of power frames 31 to move simultaneously.

[0040] Specifically, the moving unit 40 includes a screw rod 29, which is rotatably installed on the loading trolley 1. Both ends of the screw rod 29 drive a group of moving bars 30 to move. The moving bars 30 are fixedly connected to the power frame 31 on the same side. The screw rod 29 is driven by a worm 27 rotatably installed on the loading trolley 1.

[0041] Specifically, the worm 27 is perpendicular to the screw 29 and meshes with a worm wheel 28 fixedly mounted on the screw 29 . A gear 33 is fixedly mounted on one end of the worm 27 away from the screw 29 , and the gear 33 meshes with a rack 34 provided on the loading trolley 1 .

[0042] Specifically, a slide groove 26 is provided on the feeding trolley 1 , and a slider 35 is slidably installed in the slide groove 26 . The slider 35 is fixedly connected to the rack 34 , and a limit ring 36 is fixedly installed on the slider 35 .

[0043] In actual application of this embodiment, when the material discharging rack 2 is placed on the placement shaft 21, the distance between the two sets of guide plates 32 is the largest. When the material discharging rack 2 is placed on the placement shaft 21, the user inserts one foot into the limiting ring 36 and then pushes the slider 35 to move to the other side of the slide groove 26. The slider 35 drives the rack 34 to move, and then drives the worm 27 to rotate under the action of the meshing rack 34 and the gear 33. The worm 27 drives the screw 29 to rotate through the meshing worm gear 28. The screw 29 drives the two sets of moving bars 30 to move inward at the same time, and then the moving bars 30 drive the guide plates 32 to move inward at the same time through the power frame 31. When the guide plate 32 moves inward, it will contact the guide cylinder 37. Since the contact position between the guide plate 32 and the guide cylinder 37 is inclined outward, the guide plate 32 will push the unloading rack 2 on the placement shaft 21 to move in the direction close to the first bracket 18 through the guide cylinder 37. At the same time, the placement plate 20 will also move along the direction of the limit plate 23 on the loading trolley 1, thereby causing the unloading rack 2 to move to the middle position of the loading trolley 1. When the two sets of guide plates 32 are in contact with the guide cylinders 37 on both sides at the same time, the unloading rack 2 is located in the middle position of the loading trolley 1. At this time, the guide plate 32 continues to move inward to push the unloading rack 2 to contact the first bracket 18 and press the unloading rack 2 against the first bracket 18, thereby realizing the centering positioning and fixation of the unloading rack 2. Subsequently, the loading trolley 1 is pushed to move to the position of the loading platform 4 and docked with the loading platform 4. After the docking is completed, the screw rod 29 is rotated in the opposite direction, so that the two sets of guide plates 32 are separated from each other until the width of the parallel sections of the two sets of guide plates 32 is the same as the maximum width between the two sets of guide cylinders 37. At this time, the guide plates 32 are no longer fixed to the unloading rack 2, and the staff pushes the unloading rack 2 to move to the upper loading platform 4; When the force used by the staff to push the unloading rack 2 to move is perpendicular to the rotation axis of the placement shaft 21, the unloading rack 2 can be directly positioned and moved onto the loading platform 4. When the force used by the staff to push the unloading rack 2 to move is not perpendicular to the rotation axis of the placement shaft 21, the unloading rack 2 will drive the placement plate 20 to move horizontally along the limit plate 23 during the process of moving to the upper loading platform 4. When the guide cylinder 37 on the side of the unloading rack 2 contacts the position inclined outwardly by the guide plate 32, the unloading rack 2 will drive the placement plate 20 to move to the middle position again under the action of the guide plate 32. Finally, the two sets of guide cylinders 37 contact the guide plates 32 on both sides at the same time, thereby realizing the re-centering of the unloading rack 2, ensuring that the unloading rack 2 can move to the accurate position on the loading platform 4, improving the loading accuracy, and increasing the distance between the guide plates 32 during loading. The distance between the unloading rack 2 and the loading trolley 1 is reduced, so that the unloading rack 2 can be quickly placed on the loading shaft 21 without the need to position and align the unloading rack 2 before placing it, thereby improving the placement speed of the unloading rack 2 and avoiding collision when the unloading rack 2 is placed on the loading trolley 1, ensuring the stable and accurate placement of the IGBT module, and then reducing the distance between the guide plates 32 so that the guide plates 32 apply pressure to the unloading rack 2 to fix it, and while pressing and fixing it, the unloading rack 2 is moved to the middle position and positioned in the center, avoiding the cumbersome process caused by separate positioning and fixing, reducing the workload, and facilitating the subsequent direct pushing of the unloading rack 2 to move. When the unloading rack 2 leaves, the distance between the guide plates 32 is set to limit the path of the unloading rack 2 leaving, thereby ensuring that the path of the unloading rack 2 moving to the loading platform 4 is the path after accurate positioning, thereby ensuring the accuracy of the position of the unloading rack 2.

[0044] like Figure 1As shown, an IGBT module feeding system provided by the present invention, the power component 39 includes a mounting plate 9, the mounting plate 9 is fixedly mounted on the base plate 17 and is provided with a Y-axis servo module 10, an X-axis servo module 11 and a Z-axis servo module 12 for grabbing material, which are driven and used in sequence. The Z-axis servo module 12 drives the rotating pneumatic clamp 13 to move.

[0045] In actual application of this embodiment, the material grabbing Y-axis servo module 10 drives the material grabbing X-axis servo module 11 to move in the Y-axis direction, the material grabbing X-axis servo module 11 drives the material grabbing Z-axis servo module 12 to move in the X-axis direction, and the material grabbing Z-axis servo module 12 drives the rotating pneumatic clamp 13 to move in the Z-axis direction, so that the rotating pneumatic clamp 13 can finally reach any point covered by the material grabbing Y-axis servo module 10, the material grabbing X-axis servo module 11 and the material grabbing Z-axis servo module 12 in the space, and then the rotating pneumatic clamp 13 can accurately move to the material placement position to clamp the material and place the material at the accurate position, thereby ensuring the accurate position of the material during the movement process and avoiding errors and deviations that may occur in human operation.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0047] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
