[0001] This invention relates to the field of equipment for processing circular sheet metal parts, and particularly to a trimming device and method for finished sheet metal parts. Background Technology

[0002] Sheet metal parts often suffer from burrs, unevenness, or dimensional deviations at the edges due to stamping, cutting, and other processes during manufacturing. These issues necessitate trimming. Trimming circular sheet metal parts often relies on manual operation or semi-automated equipment, resulting in low efficiency, poor consistency, and high labor intensity. While some automated trimming equipment exists, it suffers from discontinuous feeding, insufficient positioning accuracy, and poor adaptability. Its performance is particularly poor in areas such as changing the posture of circular sheet metal parts, continuous processing of multiple workpieces, and real-time quality monitoring, failing to meet the demands of high-efficiency and high-precision modern production. Therefore, there is an urgent need for a trimming device and method that can achieve fully automated feeding, precise positioning, adaptive processing, and intelligent sorting.

[0022] like Figure 1 As shown, it includes: a loading assembly 1, which includes a temporary storage box 11, a loading component 12, and a return plate 13. The temporary storage box 11 is used to temporarily store circular sheet metal parts. The loading component 12 is fixedly installed at an angle inside the temporary storage box 11 to transport the circular sheet metal parts from bottom to top. The return plate 13 is fixedly installed on the side of the loading component 12. A transport assembly 2 includes a transport component 21 and a bending plate 22. The transport component 21 is fixedly installed on the top of the loading component 12 to transport a single horizontal circular sheet metal part. The bending plate 22 is fixedly installed on the side of the transport component 21. Through the cooperation of the transport component 21 and the bending plate 22, the transport is realized and the circular sheet metal parts are changed from horizontal to vertical. A trimming assembly 3 includes... The system includes a limiting component 31, a transfer component 32, a trimming component 33, a blanking component 34, and a processing component 35. One end of the limiting component 31 is fixedly connected to the side of the bending plate 22 for transporting vertical circular sheet metal parts one by one. The transfer component 32 is connected to the other end of the limiting component 31. The trimming component 33 is installed on the surface of the transfer component 32 for transferring individual circular sheet metal parts for processing. The blanking component 34 is used to automatically blank the processed circular sheet metal parts. The processing component 35 is fixedly installed on the surface of the transfer component 32 for processing the circular sheet metal parts. The width of the transport component 21 is set to be greater than the width of the circular sheet metal parts. The limiting component 31, the transfer component 32, the trimming component 33, the blanking component 34, and the processing component 35 are controlled by a unified system.

[0023] Finished sheet metal parts trimming equipment includes the following specific steps: S1. Intelligent feeding and posture recognition: The circular sheet metal parts to be trimmed are placed in the temporary storage box 11. The circular sheet metal parts are transported from bottom to top to the transport component 2 one by one through the inclined conveyor belt 121 and support block 122 of the feeding component 12. The mounting frame 211 of the transport component 21 receives the circular sheet metal parts and, through the cooperation of the horizontal conveyor belt 212 and the bending plate 22, turns the circular sheet metal parts from a horizontal state to a vertical state. S2. Multi-level limiting and precise positioning: The vertical circular sheet metal parts enter the limiting component 31 through the transport channel 311 and are positioned one by one by the limiting machine 312; the fixing plate 323 of the transfer component 32 clamps the circular sheet metal parts and performs precise positioning on the worktable 321 through the first moving seat 322, and transfers the circular sheet metal parts to the trimming station; S3. Adaptive trimming and real-time monitoring: The turning tool 332 of the trimming component 33 performs trimming processing on the circular sheet metal part under the drive of the mounting base 331. During the processing, the cutting parameters are adaptively adjusted according to the material and thickness of the circular sheet metal part. The second push rod 353 of the processing component 35 assists in positioning and processing the circular sheet metal part through the limiting sleeve 352. At the same time, the processing force is monitored in real time by the force sensor to prevent over-cutting or under-cutting. S4. Quality Inspection and Intelligent Sorting and Unloading: After processing, the trimming quality is inspected in real time by an optical inspection device set near the trimming station to determine whether it is qualified; the second moving seat 341 of the unloading component 34 drives the unloading channel 342 to the processing position to receive the round sheet metal parts that have been trimmed, and sorts and transports them to the qualified product area or rework area according to the inspection results.

[0024] like Figure 2 As shown, the temporary storage box 11 includes an inclined conveyor belt 121 and support blocks 122. One end of the inclined conveyor belt 121 is fixedly installed inside the temporary storage box 11, and several support blocks 122 are fixedly connected to the outer surface of the inclined conveyor belt 121 at equal intervals.

[0025] When trimming the circular sheet metal parts, the parts to be trimmed are first placed inside the temporary storage box 11. The inclined conveyor belt 121 is then turned on, and the circular sheet metal parts are supported by the support block 122 and lifted along the inclined conveyor belt 121. When the circular sheet metal parts are lifted to the highest point of the inclined conveyor belt 121, they fall down. The inclined plate causes the circular sheet metal parts to slide towards the horizontal conveyor belt 212. Due to the large number of parts, in order to ensure that each circular sheet metal part is driven by the horizontal conveyor belt 212, the width of the horizontal conveyor belt 212 is set to be greater than the width of the circular sheet metal parts. At this time, one side of the mounting frame 211 is closed and the other side is open. When two circular sheet metal parts are side by side on the surface of the horizontal conveyor belt 212, the outer circular sheet metal part will be blocked by the side of the mounting frame 211 as it moves and fall into the return plate 13, thus falling back into the temporary storage box 11. This process is repeated.

[0026] like Figure 3 As shown, the transport component 21 includes a mounting frame 211 and a horizontal conveyor belt 212. The mounting frame 211 is fixedly installed at the other end of the inclined conveyor belt 121, and the horizontal conveyor belt 212 is fixedly installed inside the mounting frame 211. One end of the curved plate 22 is fixedly connected to the side of the mounting frame 211, and the other end is set to be curved.

[0027] The circular sheet metal part begins to move when it falls onto the horizontal conveyor belt 212. When the circular sheet metal part reaches the other end of the horizontal conveyor belt 212, it is affected by the bending of the bending plate 22 and moves along the bending plate 22 toward the outer end of the horizontal conveyor belt 212. When it reaches the outer end of the horizontal conveyor belt 212, the inclined plate on the outer side of the mounting frame 211 is tilted. When the circular sheet metal part moves to the inclined plate, half of the circular sheet metal part is supported by the inclined plate, and the other half is not supported by the force of gravity and falls, thus falling into the transport channel 311. This causes the circular sheet metal part to change from a horizontal state to a vertical state during the falling process.

[0028] like Figure 4 As shown, the limiting component 31 includes a transport channel 311, a limiting mechanism 312, and a long plate 313. One end of the transport channel 311 is connected to the side end of the mounting frame 211 and is located directly below the curved end of the curved plate 22. The limiting mechanism 312 is fixedly installed on the side end of the other end of the transport channel 311, and the long plate 313 is fixedly connected to the bottom of the other end of the transport channel 311. The transfer component 32 includes a worktable 321, a first movable seat 322, a fixed plate 323, and a first push rod 324. The first movable seat 322 is fixedly installed on the worktable 321. 1. At the top, a fixed plate 323 is connected to the surface of the first movable seat 322. A first push rod 324 is fixedly installed inside the fixed plate 323. The trimming component 33 includes a mounting base 331 and a turning tool 332. The mounting base 331 is connected to the surface of the first movable seat 322, and the turning tool 332 is fixedly installed on the surface of the mounting base 331. The unloading component 34 includes a second movable seat 341 and an unloading channel 342. The second movable seat 341 is fixedly installed on the top of the worktable 321, and the unloading channel 342 is fixedly installed on the surface of the second movable seat 341.

[0029] The circular sheet metal part falls vertically into the transport channel 311. It then slides down the channel to the bottom, where it is blocked by a limit switch 312. A stop on the outer surface of the limit switch 312 prevents the circular sheet metal part from moving. Just before processing, the limit switch 312 electrically retracts its internal stop, allowing the single circular sheet metal part to continue moving from the bottom of the transport channel 311. The disc-shaped sheet metal piece falls into the fixed plate 323 through the opening of the part. After a single disc-shaped sheet metal piece passes through, the baffle of the limiter 312 quickly pops out to continue blocking the remaining disc-shaped sheet metal pieces. The other end of the disc-shaped sheet metal piece that has fallen into the fixed plate 323 is blocked by the long plate 313, so that the disc-shaped sheet metal piece is temporarily stored in the fixed plate 323 in a vertical state. Then, through the movement of the first moving seat 322 on the surface of the worktable 321, the fixed plate 323 is moved to the limit. The first push rod 324 pushes the circular sheet metal part into the limiting cylinder 352. Then, the first moving seat 322 moves again so that the turning tool 332 moves to the side of the circular sheet metal part to trim the edge of the circular sheet metal part. At this time, the fixing plate 323 moves to the bottom of the transport channel 311. The limiting machine 312 allows another circular sheet metal part to pass through. After the turning tool 332 completes the processing of a circular sheet metal part, there is a certain gap between the mounting seat 331 and the fixing plate 323 during the movement of the first moving seat 322. At this time, the second moving seat 341 controls the unloading channel 342 to move to the bottom of the limiting cylinder 352. The second push rod 353 pushes the processed circular sheet metal part into the unloading channel 342 and slides down. According to the feedback of the optical detection device, the second moving seat 341 controls the movement position of the unloading channel 342 so that the circular sheet metal part falls into different recycling bins. The limiting component 31, transferring component 32, trimming component 33, and unloading component 34 are driven by a unified system. When the circular sheet metal part moves to the limiting machine 312, the limiting machine 312 detects the presence of the circular sheet metal part. Subsequently, the first moving seat 322 receives an instruction, and both the fixing plate 323 and the mounting seat 331 are positioned above the first moving seat 322 and move together under the drive of the first moving seat 322. When the first moving seat 322 moves the fixing plate 323 to the lower end of the transport channel 311, the baffle of the limiting machine 312 retracts, causing the circular sheet metal part to move freely. The metal part falls into the fixed plate 323. Then the first moving seat 322 moves to the fixed seat 351 for processing. After processing, the first moving seat 322 moves to the far end of the limiting component 31. At this time, the second moving seat 341 drives the unloading channel 342 to the front end of the fixed seat 351 to receive the processed round sheet metal part. Then the unloading channel 342 moves out, and the first moving seat 322 moves to the bottom of the transport channel 311. The limiting machine 312 releases the next round sheet metal part for movement. This process is repeated.

Various modifications and variations can be made to the present invention by those skilled in the art.
