Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to an automatic loading and unloading system with quick changeover capability. Background Technology

[0002] In modern industrial production, automated material handling systems are one of the key technologies for improving production efficiency, reducing labor intensity, and enhancing product quality. Especially in scenarios of multi-variety, small-batch production, rapid changeover capability has become an important indicator for measuring the performance of automated systems.

[0003] In traditional automated loading and unloading systems, clamping plates are generally fixed with bolts. While this method is relatively simple in structural design, it has many obvious shortcomings and limitations in actual production. This is especially true when companies face multi-variety, small-batch production tasks and need to frequently change clamping plates of different shapes or sizes to meet the needs of gripping and handling different materials. The drawbacks of bolt fixing become increasingly apparent. Every time a clamping plate is replaced, the operator needs to use tools to loosen and remove multiple bolts one by one, then remove the old clamping plate, install the new clamping plate, and retighten all bolts to ensure it is firmly fixed. This process is not only cumbersome but also consumes a lot of time and energy, resulting in a significant increase in equipment downtime. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic loading and unloading system with quick model change capability.

[0005] This utility model is achieved using the following technical solution: an automatic loading and unloading system with quick-change capability, comprising a movable plate and a top plate. An assembly sleeve is fixedly connected to the lower surface of the movable plate. Pop-out holes are provided on both sides of the assembly sleeve. An installation post is snapped into the interior of the assembly sleeve. A clamping plate is fixedly connected to the lower surface of the installation post. Spring grooves are provided on both sides of the installation post. A telescopic spring is fixedly connected to the inner wall of the spring groove. A reset pin is fixedly connected to the surface of the telescopic spring. Extension frames are fixedly connected to both sides of the lower surface of the movable plate. A movable slider is slidably connected inside the extension frame. A tamping rod is fixedly connected to the surface of the movable slider. A push rod is fixedly connected to the surface of the movable slider.

[0006] Through the above technical solution and the quick-assembly and disassembly design, personnel can flexibly change the clamping plate to match the shape of the actual material, ensuring that the material can be stably clamped during subsequent loading and unloading operations. This improves the stability of loading and unloading, effectively avoids material damage or operational errors caused by unstable clamping, and improves production efficiency and product quality.

[0007] As a further improvement to the above solution, the inner wall of the extension frame is provided with a groove, the movable slider is slidably connected to the inside of the groove, and the tamping rod is located on one side of the reset pin.

[0008] As a further improvement to the above solution, the reset pin is adapted to the pop-out hole, and the reset pin passes through the pop-out hole and is inserted into the interior of the extension frame.

[0009] As a further improvement to the above solution, a bearing seat is fixedly connected to the lower surface of the top plate, and a bidirectional lead screw is rotatably connected to the surface of the bearing seat.

[0010] As a further improvement to the above solution, two movable plates are provided, and the two movable plates are respectively threaded to both sides of the surface of the bidirectional lead screw.

[0011] As a further improvement to the above solution, limit rods pass through both sides of the movable plate, and supports are fixedly connected to both ends of the limit rods, which are fixedly connected to the lower surface of the top plate.

[0012] As a further improvement to the above solution, a mounting shell is fixedly connected to the surface of the movable plate, a drive motor is fixedly connected to the inner wall of the mounting shell, and the bidirectional lead screw is fixedly connected to the output end of the drive motor.

[0013] The above technical solution, through the cooperation of the drive motor and the bidirectional lead screw, realizes the control of the movement of the movable plate, eliminating the need for manual adjustment of the clamping plate position, and greatly improving production efficiency and ease of operation.

[0014] As a further improvement to the above solution, preset bolt blocks are fixedly connected at the four corners of the outer surface of the top plate, and bolt holes are opened on the surface of the preset bolt blocks.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a push rod to move a movable slider, which in turn causes the tamping rod to press the reset pin, compressing the telescopic spring and allowing the reset pin to quickly disengage from the pop-up hole. This facilitates the easy removal of the mounting post and the disassembly of the clamping plate. When replacing the clamping plate, pressing the reset pin and inserting it into the mounting post causes the pop-up hole to overlap with the reset pin. Under the reset action of the telescopic spring, the reset pin quickly extends and engages with the pop-up hole, forming a snap-fit ​​structure. This enables rapid installation of the clamping plate, significantly shortening changeover time and avoiding the problems of long downtime, time-consuming, and labor-intensive processes caused by traditional bolt fixing and complex disassembly and assembly. It ensures the continuity and stability of production, enhances the system's flexibility, and allows it to quickly respond to the production needs of different material shapes.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] Please combine Figure 1-4 This embodiment of an automatic loading and unloading system with quick-change capability includes a movable plate 1 and a top plate 13. An assembly sleeve 2 is fixedly connected to the lower surface of the movable plate 1. Pop-out holes 3 are provided on both sides of the assembly sleeve 2. A mounting post 4 is snapped into the interior of the assembly sleeve 2. A clamping plate 5 is fixedly connected to the lower surface of the mounting post 4. Spring grooves 6 are provided on both sides of the mounting post 4. A telescopic spring 7 is fixedly connected to the inner wall of the spring groove 6. A reset pin 8 is fixedly connected to the surface of the telescopic spring 7. Extension frames 9 are fixedly connected to both sides of the lower surface of the movable plate 1. The extension frames 9 slide internally. A movable slider 10 is connected, and a tamping rod 11 is fixedly connected to the surface of the movable slider 10. A push rod 12 is also fixedly connected to the surface of the movable slider 10. When it is necessary to replace the clamping plate 5 with a different shape, the operator first presses the push rod 12. The push rod 12 pushes the movable slider 10 to slide along the inside of the extension frame 9. The movable slider 10 drives the tamping rod 11 to move and squeeze the reset pin 8. After being compressed, the reset pin 8 compresses the telescopic spring 7 and retracts into the spring groove 6. When the reset pin 8 disengages from the pop-up hole 3, the mounting post 4 can be removed from the assembly sleeve 2, thus disassembling the clamping plate 5. After replacing the clamping plate 5 with a suitable one, during assembly, press the reset pins 8 on both sides to compress the telescopic spring 7 and retract it into the spring groove 6. Insert the mounting post 4 into the assembly sleeve 2. When the mounting post 4 is installed in place and the pop-up hole 3 overlaps with the reset pin 8, the reset pin 8 extends under the reset action of the telescopic spring 7 and engages with the pop-up hole 3, forming a snap-fit ​​structure, thus completing the installation of the clamping plate 5.

[0020] The inner wall of the extension frame 9 is provided with a sliding groove, the movable slider 10 is slidably connected to the inside of the sliding groove, and the tamping rod 11 is located on one side of the reset pin 8. When the push rod 12 is pressed, the movable slider 10 slides in the sliding groove, driving the tamping rod 11 to move, thereby realizing the squeezing operation on the reset pin 8.

[0021] The reset pin 8 is adapted to the pop-out hole 3. The reset pin 8 passes through the pop-out hole 3 and is inserted into the inside of the extension frame 9. When the clamping plate 5 is removed, the reset pin 8 is compressed and retracted into the spring groove 6, and can be smoothly disengaged from the pop-out hole 3. When the clamping plate 5 is installed, the reset pin 8 extends under the reset action of the telescopic spring 7 and accurately engages in the pop-out hole 3, forming a stable engagement structure.

[0022] A bearing seat 14 is fixedly connected to the lower surface of the top plate 13, and a two-way lead screw 15 is rotatably connected to the surface of the bearing seat 14.

[0023] There are two movable plates 1, which are threaded to both sides of the surface of the bidirectional lead screw 15.

[0024] Limiting rods 16 pass through both sides of the movable plate 1, and supports are fixedly connected to both ends of the limiting rods 16. The supports are fixedly connected to the lower surface of the top plate 13.

[0025] A mounting shell 17 is fixedly connected to the surface of the movable plate 1. A drive motor 18 is fixedly connected to the inner wall of the mounting shell 17. A bidirectional lead screw 15 is fixedly connected to the output end of the drive motor 18. After the drive motor 18 starts, it drives the bidirectional lead screw 15 to rotate. The rotation of the bidirectional lead screw 15 causes the movable plates 1 on both sides to move synchronously along the limit rod 16 towards the center. The movement of the movable plate 1 drives the clamping plate 5 that is snapped onto the surface of the assembly sleeve 2 to move and clamp the material. After clamping, subsequent loading and unloading operations can be performed.

[0026] Pre-set bolt blocks 19 are fixedly connected to the four corners of the outer surface of the top plate 13. The surface of the pre-set bolt blocks 19 has bolt holes. By passing the bolts through the bolt holes, this device can be installed on external driving equipment, such as a robotic arm. After installation, the movement of the external equipment drives this device to clamp materials and perform loading and unloading operations.

[0027] The implementation principle of the quick-change automatic loading and unloading system in this application embodiment is as follows: Personnel first install the device onto an external driving device, such as a robotic arm, using bolts. After installation, the external device moves, causing the device to clamp the material and complete the loading and unloading operation.

[0028] Subsequently, after the drive motor 18 starts, it drives the bidirectional lead screw 15 to rotate, causing the two movable plates 1 on both sides to move synchronously along the limit rod 16 towards the center. The movement of the movable plates 1 causes the clamping plate 5 that is engaged with the surface of the assembly sleeve 2 to move, thereby clamping the material. After clamping is completed, subsequent loading and unloading operations are performed by moving external equipment.

[0029] When it is necessary to replace the clamping plate 5 with a different shape, the operator presses the push rod 12. The push rod 12 pushes the movable slider 10 to slide along the extension frame 9. The movable slider 10 drives the tamping rod 11 to move and squeeze the reset pin 8. After being compressed, the reset pin 8 compresses the telescopic spring 7 and retracts into the spring groove 6. At this time, the reset pin 8 disengages from the pop-out hole 3, and the mounting post 4 can be removed from the assembly sleeve 2, completing the disassembly of the clamping plate 5. After replacing the clamping plate 5 with a suitable one, press the reset pins 8 on both sides to compress the telescopic spring 7 and retract it into the spring groove 6. Insert the mounting post 4 into the assembly sleeve 2. In Set 2, when the mounting post 4 is in place and the pop-out hole 3 overlaps with the reset pin 8, the reset pin 8 extends under the reset action of the telescopic spring 7 and engages with the pop-out hole 3, forming a stable engagement structure and completing the installation of the clamping plate 5. The sliding groove on the inner wall of the extension frame 9 provides a stable guide for the sliding of the movable slider 10, ensuring that the tamping rod 11 can accurately squeeze the reset pin 8. The reset pin 8 is adapted to the pop-out hole 3, passes through the pop-out hole 3 and is inserted into the interior of the extension frame 9, ensuring that the reset pin 8 can smoothly disengage from the pop-out hole 3 during disassembly and can be accurately engaged during installation, forming a stable connection.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
