Furthermore, the labor costs for loading are high, and the pallet placement error is significant, affecting the efficiency and accuracy of sheet metal loading on the stamping line. Utility Model Content

[0003] The purpose of this invention is to provide an AGV loading system for the head of a stamping line, which can solve the technical problems of low efficiency and poor accuracy of loading using forklifts on stamping lines. It uses a mobile trolley to automatically move stacked sheets onto the loading trolley, which greatly improves the efficiency and accuracy of loading, reduces the production cost of the stamping line, and improves the safety of the production workshop.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] An AGV loading system for the beginning of a stamping line includes a transition pallet and a mobile trolley that shuttles back and forth between a loading area and a beginning-of-line loading area. The transition pallet carries a sheet metal pallet on which sheet metal bodies are stacked. The loading area is equipped with a reinforcing bracket and a transition bracket. The beginning-of-line loading area is equipped with a loading trolley. The mobile trolley is used to transport the transition pallet from the transition bracket to the beginning-of-line loading area. A pushing cylinder is provided on one side of the reinforcing bracket. The pushing cylinder is used to push the sheet metal pallet from the reinforcing bracket to the transition pallet of the transition bracket. The loading trolley is equipped with a gripping cylinder. The gripping cylinder is equipped with a gripping hook that works with the sheet metal pallet. The gripping cylinder is used to grip the sheet metal pallet on the transition pallet and move it onto the loading trolley.

[0006] Furthermore, the grab hook is rotatably connected to the end of the grabbing cylinder, and after the grab hook rotates, it comes into contact with one side of the inside of the sheet material tray.

[0007] Furthermore, the loading trolley is symmetrically equipped with leveling cylinders, and the movable end of the leveling cylinders contacts the side of the plate tray.

[0008] Furthermore, the movable end of the alignment cylinder is equipped with a pressure sensor for use with the sheet metal pallet.

[0009] Furthermore, there are at least two of both the reinforcing bracket and the feeding trolley.

[0010] Furthermore, the reinforcing bracket, transition tray, and loading trolley are all equipped with rollers for use with the sheet material tray.

[0011] Furthermore, the feed area at the beginning of the line is also equipped with a transition bracket for use with the transition tray.

[0023] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0024] Reference Figure 1 This utility model describes an AGV loading system for the beginning of a stamping line. The main structure includes a transition pallet 1 and a mobile trolley 4 that shuttles between the loading area 2 and the beginning-of-line loading area 3. The mobile trolley 4 is a commonly used AGV trolley structure in the prior art, capable of movement and lifting to achieve automatic material handling and transfer. The mobile trolley 4 can transfer sheet metal loaded in the loading area 2 to the beginning-of-line loading area 3. The transition pallet 1 is used to temporarily support the sheet metal; its specific structure can use a common pallet structure found in the market. The transition pallet 1 supports sheet metal pallets 5, on which sheet metal bodies 6 are stacked. The sheet metal bodies 6 used for stamping production are stacked on the sheet metal pallet 5. During hoisting, the hoisting equipment lifts the sheet metal pallet 5, facilitating the hoisting and movement of the sheet metal bodies 6. The sheet metal pallets 5 are placed on the transition pallet 1 for temporary transfer and support. The loading area 2 is used for loading sheet metal. The beginning-of-line loading area 3 is located on one side of the beginning of the stamping line. (Refer to...) Figure 2 and Figure 3 The loading area 2 is equipped with a reinforcing bracket 7 and a transition bracket 8. The reinforcing bracket 7 and transition bracket 8 are generally made of metal and serve a supporting function. The transition tray 1 is placed on the transition bracket 8, and the top of the transition tray 1 and the top of the reinforcing bracket 7 are at the same height. Figure 4 and Figure 5The loading area 3 at the beginning of the line is equipped with a loading trolley 9, which can move and rise. The loading robot picks up the top layer of sheet metal and loads it onto the stamping line. The loading trolley 9 then rises to maintain the top layer of sheet metal at a designated height, ensuring the accuracy of the robot's loading. The moving trolley 4 is used to transport the transition pallet 1 from the transition bracket 8 to the loading area 3 at the beginning of the line. Specifically, the moving trolley 4 moves to below the transition pallet 1, rises to contact the bottom of the transition pallet 1, and lifts it up, thereby enabling the transition pallet 1 to automatically move into the loading area 3 at the beginning of the line. One side of the reinforcing bracket 7 is welded or... A push cylinder 10 is bolted to the plate tray 5. The push cylinder 10 can adopt a commonly used cylinder structure on the market. The push cylinder 10 is used to push the plate tray 5 from the reinforcing bracket 7 to the transition tray 1 of the transition bracket 8. The transition tray 1 is placed on the transition bracket 8. The hoisting equipment hoists the plate tray 5 containing the plate body 6 and places it on the reinforcing bracket 7 to avoid potential impact damage to the transition tray 1. Then, the push cylinder 10 is activated, pushing the plate tray 5 onto the transition tray 1 of the transition bracket 8. Afterwards, the moving trolley 4 moves to below the transition tray 1 and rises until it contacts the bottom of the transition tray 1. The transition tray 1 is lifted, separating it from the transition support 8, allowing it to automatically move to the line-start loading area 3. A gripping cylinder 11 is fixed to the loading trolley 9 by welding or bolts. The gripping cylinder 11 uses a commonly available cylinder structure. It has a gripping hook 12 that works with the sheet metal tray 5. The gripping cylinder 11 grips the sheet metal tray 5 on the transition tray 1 and moves it to the loading trolley 9. The moving trolley 4 moves the transition tray 1 to the line-start loading area 3, bringing it close to the loading trolley 9. The moving trolley 4 uses lifting and lowering to keep the transition tray 1 in contact with the loading trolley 9. When the trolley 9 is at the same height, the gripping cylinder 11 extends so that the gripping hook 12 at its movable end contacts and grips the sheet material pallet 5 on the transition pallet 1. Then, the gripping cylinder 11 retracts, moving the sheet material pallet 5 from the transition pallet 1 to the loading trolley 9, thereby realizing the automatic transfer of the sheet material pallet 5. This operation can realize the automatic loading of the sheet material pallet 5 containing the sheet material body 6 without human intervention, which greatly reduces the labor cost required in the loading process and improves the efficiency and convenience of loading. The moving trolley 4 moves in a directional manner according to the set route, avoiding the risk of collision between equipment and ensuring the safety of the workshop production process.

[0025] Preferred, refer to Figure 6The gripping hook 12 is rotatably connected to the end of the gripping cylinder 11 via a pin or hinge. After rotating, the gripping hook 12 contacts one side of the inside of the sheet material tray 5. The side of the sheet material tray 5 has a notch. When the gripping hook 12 is in a horizontal state, its height is low. It can pass through the notch and move to the bottom of the sheet material tray 5 under the push of the gripping cylinder 11. Then, the gripping hook 12 is driven to rotate by a motor or other power components, so that it rotates to a vertical state, thereby increasing the vertical height of the gripping hook 12 and contacting one side of the inside of the sheet material tray 5. Then, the gripping cylinder 11 retracts, which can drive the sheet material tray 5 to move together. The structure is simple and the gripping operation of the sheet material tray 5 is more efficient and convenient.

[0026] Preferably, the loading trolley 9 is symmetrically fixed with straightening cylinders 13 by welding or bolts. The movable end of the straightening cylinder 13 contacts the side of the sheet material pallet 5. Before the sheet material pallet 5 is gripped, the straightening cylinders 13 on both sides extend simultaneously until they contact the side of the sheet material pallet 5 at the same time, thereby realizing the straightening operation of the sheet material pallet 5. This makes the position of the sheet material pallet 5 when it is moved onto the loading trolley 9 more accurate, and further improves the accuracy of sheet material loading.

[0027] Preferably, the movable end of the straightening cylinder 13 is equipped with a pressure sensor 14 for use with the sheet metal tray 5. The pressure sensor 14 can adopt the common contact pressure sensor structure on the market. Specifically, the I2C model pressure sensor sold by Shidefu Measurement & Control Technology (Shanghai) Co., Ltd. can be used. The pressure sensor 14 is electrically connected to the straightening cylinder 13. When the pressure sensors 14 on both sides are in contact with the sheet metal tray 5, they transmit a signal to the straightening cylinder 13, so that the straightening cylinder 13 stops moving in time, making the straightening operation of the sheet metal tray 5 more accurate.

[0028] Preferably, there are at least two reinforcing brackets 7 and at least two loading trolleys 9. This arrangement allows the transition bracket 8 on the side of the other reinforcing bracket 7 to hold empty transition pallets 1 while one reinforcing bracket 7 is loading sheet metal. This enables multiple transition pallets 1 to continuously cycle and ensure the continuity of sheet metal loading. Similarly, after one loading trolley 9 finishes loading, it can be replenished with sheet metal by a moving trolley 4. During this process, the other loading trolley 9 loads sheet metal, ensuring that the loading of the stamping line is uninterrupted and the continuity of stamping production is guaranteed.

[0029] Preferably, the reinforcing bracket 7, the transition tray 1, and the loading trolley 9 are all equipped with rollers 15 for use with the sheet material tray 5. The sheet material tray 5 is placed on the rollers 15, which makes it easier to push the sheet material tray 5, thereby making the transfer of the sheet material tray 5 between the reinforcing bracket 7, the transition tray 1, and the loading trolley 9 smoother.

[0030] Preferably, the feed area 3 at the beginning of the line is also provided with a transition bracket 8 for use with the transition tray 1. This structure allows the moving trolley 4 to transfer the transition tray 1 and place it on the transition bracket 8. At this time, the transition tray 1 on the transition bracket 8 is automatically at the same height as the feed trolley 9, and there is no need to adjust the height of the moving trolley 4, which further improves the convenience and accuracy of transferring the sheet material tray 5 to the feed trolley 9.

[0031] Working Principle: The structure of this utility model uses a transition pallet 1 and a moving trolley 4. The transition pallet 1 is used to move the pallet 5 containing the main body of the sheet material 6 from the loading area 2 to the line-start loading area 3, and then transfer it to the loading trolley 9. This process does not require human intervention, reducing labor and forklift usage costs, greatly improving loading efficiency and convenience, and enhancing workshop safety. The hoisting equipment places the pallet 5 containing the main body of the sheet material 6 on the reinforcing bracket 7, and then uses the push cylinder 10 to move the pallet 5 to the transition pallet 1 on the transition bracket 8, thereby avoiding potential damage to the transition pallet 1. Then, the moving trolley 4 drives the transition pallet 1 to automatically move into the line-start loading area 3. After the moving trolley 4 is aligned with the loading trolley 9, the gripping cylinder 11 uses the gripping hook 12 to grab the pallet 5 on the transition pallet 1 and move it to the loading trolley 9, thus realizing automatic loading and rapid transfer of the sheet material. The transfer process is faster and more accurate, further improving loading efficiency and accuracy.
