Description

Technical Field

[0001] This utility model belongs to the field of transfer and conveying carrier pallet technology, and relates to a compact pallet-collecting and rotating up-and-down switching device. Background Technology

[0002] A power module is a modular assembly of power electronic devices combined with specific functions and then encapsulated. It is an advanced hybrid integrated power component with an IGBT (Insulated Gate Bipolar Transistor) as its core, consisting of a high-speed, low-power IGBT die, optimized gate drive circuitry, and fast protection circuitry. The transfer and transport of the carrier tray is a crucial step in automated semiconductor production. Current technologies use 3-axis module mechanisms or robots to achieve this, which, while functional, result in high costs, large space requirements in the production workshop, high maintenance costs, and a waste of valuable production space.

[0003] To address this issue, a compact rotating and repositioning device for the tray is designed to overcome the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a compact plate rotating and repositioning device that is simple and reasonable in structure, practical and convenient, small in size and low in cost.

[0005] This utility model is achieved through the following technical solution: a compact tray-receiving and rotating device, comprising a platform and a conveyor line, a lifting mechanism, a rotating mechanism, and a carrier tray mounted on the platform. The conveyor line consists of a first conveyor line and a second conveyor line. The horizontal height of the first conveyor line is higher than that of the second conveyor line, and the ends of the first and second conveyor lines are adjacent to each other and form an angle between them. A carrier tray is placed on the first conveyor line, and a lifting mechanism is provided on one side of the first conveyor line. A rotating mechanism is provided on the lifting mechanism, and a gripper assembly is installed on the rotating mechanism. After the lifting mechanism and the rotating mechanism drive the gripper assembly to move up and down and adjust the angle, the gripper assembly sequentially clamps each carrier tray placed on the first conveyor line onto the second conveyor line.

[0006] Preferably, the lifting mechanism consists of a guide rod cylinder, a cylinder limiting pad, and a cylinder mounting seat. The cylinder mounting seat is vertically fixed to the platform by bolts at a position near the carrier pallet on one side of the first conveyor line. A triangular reinforcing block is provided on the side of the cylinder mounting seat away from the carrier pallet, and a guide rod cylinder is installed on the other side. A cylinder limiting pad is installed at the top of the cylinder mounting seat between the guide rod cylinder and the cylinder mounting seat. A rotating mechanism is installed on the piston rod end of the guide rod cylinder, and the rotating mechanism moves up and down by the piston rod of the guide rod cylinder.

[0007] Preferably, the rotating mechanism consists of a fixed connecting frame, a rotating cylinder, a first rotating buffer limit block, and a rotating lower connecting plate. The fixed connecting frame is provided with long strip-shaped reinforcing ribs to improve overall strength. One end of the fixed connecting frame is connected to the piston rod of the guide rod cylinder by bolts, and the other end is equipped with a rotating cylinder. The rotating cylinder is connected to one side of the rotating lower connecting plate, and the other side of the rotating lower connecting plate is connected to the gripper assembly. After the rotating cylinder is vented, the gripper assembly connected to the rotating lower connecting plate can rotate forward and backward together. A first rotating buffer limit block matching the gripper assembly is installed on the bottom surface of the fixed connecting frame to position the gripper assembly when it rotates into place, reducing impact and thus improving service life.

[0008] Preferably, the gripper assembly comprises a first miniature sliding cylinder, a first gripper, a gripper connecting seat, a second rotary buffer limiting block, a second gripper, and a second miniature sliding cylinder. The gripper connecting seat is connected to a rotating lower connecting plate by bolts. A first gripper and a second gripper are symmetrically arranged on opposite sides of the gripper connecting seat. A first miniature sliding cylinder and a second miniature sliding cylinder are mounted on the gripper connecting seat at the ends of the first and second grippers. The first and second miniature sliding cylinders are connected to... The first and second grippers are connected. The first and second small sliding table cylinders drive the first and second grippers to extend or retract simultaneously along the length of the gripper connecting seat. A second rotation buffer limit block is provided on the gripper connecting seat for positioning the gripper assembly when it is rotated into place. U-shaped limiting grooves corresponding to the carrier tray are provided on the inner sidewalls of the first and second grippers. When the first and second grippers retract, the opposite sides of the carrier tray slide into the U-shaped limiting grooves and clamp them.

[0009] Preferably, the gripper connecting seat is provided with a check mechanism, which consists of a connecting block and a check element. The connecting block is bolted to the end of the first or second gripper near the carrier pallet, and a check element is installed on the connecting block. The check element and the first or second gripper form a gap for the carrier pallet to pass through.

[0010] The anti-return component acts as a limiting component to ensure that the vehicle pallet will not fall out of the gripper assembly after it has been fully inserted into the gripper assembly during the rotation of the vehicle pallet.

[0011] Preferably, both the first and second conveyor lines consist of a frame, a conveyor belt, and a motor. A motor is installed on one side of the frame, and the motor drives the conveyor belt to transport the carrier pallet.

[0012] Preferably, a tray receiving mechanism is provided at the end of the second conveyor line. After the carrier pallet is conveyed to the end of the second conveyor line, it is pushed into the tray receiving mechanism under the action of an external push rod. After completion, the next carrier pallet will be conveyed to wait to be pushed into the tray receiving mechanism.

[0013] Preferably, the relative angle between the second conveyor line and the first conveyor line is 90 degrees.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model provides a compact tray rotation and up-and-down switching device. After the carrier tray is transported to the other end of the line through the first conveyor line, the carrier tray is pushed into the gripper assembly by the external push rod mechanism. Once pushed into position, the rotating mechanism rotates the carrier pallet 90 degrees and aligns it with the upper part of the second conveyor line. Then, the lifting mechanism lowers the carrier pallet to bring it as close as possible to the upper surface of the second conveyor line (belt conveyor). At this time, the two cylinders of the gripper assembly extend simultaneously to open the grippers and place the carrier pallet onto the conveyor belt. The second conveyor line then moves to the other end after the carrier pallet is placed on it. Simultaneously, the two cylinders in the gripper assembly retract simultaneously to close the grippers. The cylinders in the lifting mechanism extend upward to return the gripper assembly to its original working position. Then, under the action of the rotating mechanism, it rotates 90 degrees so that the opening of the gripper assembly aligns with the upper first conveyor line, ready to receive the next carrier pallet. The entire function uses a compact mechanism to rotate the carrier pallet 90 degrees from the upper conveyor line and place it on the lower (second) conveyor line, realizing the transfer function before the carrier pallet is recycled. The entire device is simple to operate and improves work efficiency; its small size reduces costs and saves space. Attached Figure Description

[0024] To enable those skilled in the art to more clearly understand the purpose, technical solution and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] The present invention will now be described in detail with reference to the accompanying drawings: Figure 1-2 As shown, a compact tray-receiving and rotating device includes a platform (not shown) and a conveyor line, a lifting mechanism 1, a rotating mechanism 2, and a carrier tray 3 mounted on the platform. The conveyor line consists of a first conveyor line 4 and a second conveyor line 5. The horizontal height of the first conveyor line 4 is higher than that of the second conveyor line 5. The ends of the first conveyor line 4 and the second conveyor line 5 are adjacent and form an angle between them. The relative angle between the second conveyor line 5 and the first conveyor line 4 is 90 degrees. A carrier tray 3 is placed on the first conveyor line 4, and a lifting mechanism 1 is provided on one side of the first conveyor line 4. The rotating mechanism 2 is provided on the lifting mechanism 1, and a gripper assembly 6 is installed on the rotating mechanism 2. After the lifting mechanism 1 and the rotating mechanism 2 drive the gripper assembly 6 to move up and down and adjust the angle, the gripper assembly 6 sequentially clamps each carrier tray 3 placed on the first conveyor line 4 onto the second conveyor line 5.

[0027] like Figure 3As shown, the lifting mechanism 1 consists of a guide rod cylinder 7, a cylinder limiting pad 8, and a cylinder mounting seat 9. The cylinder mounting seat 9 is vertically fixed to the platform (not shown in the figure) by bolts at a position close to the carrier pallet 3 on one side of the first conveyor line 4. A triangular reinforcing block 10 is provided on the side of the cylinder mounting seat 9 away from the carrier pallet 3, and the guide rod cylinder 7 is installed on the other side. A cylinder limiting pad 8 is installed at the top position of the cylinder mounting seat 9 between the guide rod cylinder 7 and the cylinder mounting seat 9. A rotating mechanism 2 is installed on the piston rod end of the guide rod cylinder 7. The rotating mechanism 2 moves up and down by the piston rod of the guide rod cylinder 7.

[0028] When the guide rod cylinder extends with air, it can lift the mechanism mounted on the cylinder upwards. When the guide rod cylinder retracts, it can move the mechanism mounted on the cylinder downwards. At the same time, the descent height is limited by the cylinder limit pad. The entire lifting mechanism realizes the lifting function of the rotating mechanism.

[0029] like Figure 4 As shown, the rotating mechanism 2 consists of a fixed connecting frame 12, a rotating cylinder 13, a first rotating buffer limit block 14, and a rotating lower connecting plate 15. The fixed connecting frame 12 is provided with long strip-shaped reinforcing ribs 16 to improve the overall strength. One end of the fixed connecting frame 12 is connected to the piston rod of the guide rod cylinder 7 by bolts, and the other end is equipped with the rotating cylinder 13. The rotating cylinder 13 is connected to one side of the rotating lower connecting plate 15, and the other side of the rotating lower connecting plate 15 is connected to the gripper assembly 6. After the rotating cylinder 13 is vented, the gripper assembly 6 connected to the rotating lower connecting plate 15 can rotate forward and backward together. A first rotating buffer limit block 14 matching the gripper assembly 6 is installed on the bottom surface of the fixed connecting frame 12 to provide a gentler positioning when the gripper assembly 6 is rotated into place, reducing impact and thus improving service life.

[0030] like Figure 5As shown, the gripper assembly 6 comprises a first small sliding cylinder 18, a first gripper 19, a gripper connecting seat 20, a second rotary buffer limiting block 21, a second gripper 22, and a second small sliding cylinder 23. The gripper connecting seat 20 is connected to the rotating lower connecting plate 15 by bolts. The first gripper 19 and the second gripper 22 are symmetrically arranged on opposite sides of the gripper connecting seat 20. The first small sliding cylinder 18 and the second small sliding cylinder 23 are mounted on the gripper connecting seat 20 at the ends of the first gripper 19 and the second gripper 22. The first small sliding cylinder 18 and the second small sliding cylinder 23 are connected to the first gripper 19 and the second small sliding cylinder 23. The second gripper 22 is connected, and the first small sliding table cylinder 18 and the second small sliding table cylinder 23 drive the first gripper 19 and the second gripper 22 to extend or retract simultaneously along the length direction of the gripper connecting seat 20. A second rotation buffer limit block 21 is provided on the gripper connecting seat 20 to provide a gentler positioning when the gripper assembly is rotated into place, reducing impact and thus improving service life. U-shaped limiting grooves 11 corresponding to the carrier tray 3 are provided on the inner side walls of the first gripper 19 and the second gripper 22. When the first gripper 19 and the second gripper 22 retract, the opposite sides of the carrier tray 3 slide into the U-shaped limiting grooves 11 and clamp them.

[0031] like Figure 6 As shown, a check mechanism 24 is provided on the gripper connecting seat 20. The check mechanism 24 consists of a connecting block 25 and a check element 26. The connecting block 25 is bolted to the end of the first gripper 19 or the second gripper 22 near the carrier pallet 3. The check element 26 is installed on the connecting block 25. A gap is formed between the check element 26 and the first gripper 19 or the second gripper 22 for the passage of the carrier pallet 3. The check element 26 acts as a limiting element to ensure that the carrier pallet 3 will not fall out of the gripper assembly 6 during the rotation of the carrier pallet 3 after it has entered the gripper assembly 6.

[0032] like Figure 7 As shown, both the first conveyor line 4 and the second conveyor line 5 consist of a frame 27, a conveyor belt 28, and a motor 29. A motor 29 is mounted on one side of the frame 27, driving the conveyor belt 28 to transport the carrier pallet 3. A pallet-collecting mechanism (not shown in the figure) is provided at the end of the second conveyor line 5. After the carrier pallet 3 is transported to the end of the second conveyor line 5, it is pushed into the pallet-collecting mechanism by an external push rod (not shown in the figure). After completion, the next carrier pallet will be transported to wait for it to be pushed into the pallet-collecting mechanism.

[0033] This utility model provides a compact tray rotation and up-and-down switching device. After the carrier tray is transported to the other end of the line through the first conveyor line, the carrier tray is pushed into the gripper assembly by the external push rod mechanism. Once pushed into position, the rotating mechanism rotates the carrier pallet 90 degrees and aligns it with the upper part of the second conveyor line. Then, the lifting mechanism lowers the carrier pallet to bring it as close as possible to the upper surface of the second conveyor line (belt conveyor). At this time, the two cylinders of the gripper assembly extend simultaneously to open the grippers and place the carrier pallet onto the conveyor belt. The second conveyor line then moves to the other end after the carrier pallet is placed on it. Simultaneously, the two cylinders in the gripper assembly retract simultaneously to close the grippers. The cylinders in the lifting mechanism extend upward to return the gripper assembly to its original working position. Then, under the action of the rotating mechanism, it rotates 90 degrees so that the opening of the gripper assembly aligns with the upper first conveyor line, ready to receive the next carrier pallet. The entire function uses a compact mechanism to rotate the carrier pallet 90 degrees from the upper conveyor line and place it on the lower (second) conveyor line, realizing the transfer function before the carrier pallet is recycled. The entire device is simple to operate and improves work efficiency; its small size reduces costs and saves space.

[0034] The plate-receiving mechanism is an existing structure and not a core technical feature of this invention, therefore it will not be explained in detail. The first and second conveyor lines in this invention are also existing standardized conveyor lines, and will not be explained in detail thereafter.

[0035] For ease of understanding, the following is provided Figure 8 This is a schematic diagram of the structure of the carrier pallet in this utility model. Of course, the carrier pallet to be transferred and transported that this utility model can be applied to is not only as shown above, but can also be other similar structures.

[0036] The specific embodiments described herein are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
