[0052] Currently, most stamping production lines are equipped with automated handling systems, enabling the entire line to operate in a cyclical manner. However, for single presses, the worktable is larger than that of traditional presses, and the size of the parts they process exceeds the processing capacity of existing stamping production lines, making it impossible to use traditional press handling systems. In addition, due to the varying local strengths of the parts during the production process, manual handling is difficult.

[0053] Therefore, this invention provides an automated production system for a single press, aiming to solve the problem of difficult manual handling of existing single presses without establishing an entire production line. Please refer to [link / reference]. Figures 1 to 5 This is a schematic diagram of an embodiment of the automated production system for a single press provided by the present invention.

[0054] Please see Figure 1The single-press automated production system 100 has multiple zones sequentially formed, including a loading zone, a centering zone, a pressing and forming zone, an inspection zone, and a unloading zone. The single-press automated production system 100 includes a loading trolley 1, a centering device 2, a single press 3, an inspection device 4, a transfer frame 5, and multiple transfer devices 6. The loading trolley 1 is located in the loading zone and is used to carry the workpiece 9. The centering device 2 is located in the centering zone and includes a centering platform 21. The centering device 2 is used to center and position the workpiece 9 on the centering platform 21. The single press 3 is located in the pressing and forming zone. The single press 3 is equipped with multiple sets of stamping dies corresponding to different stamping processes. The inspection device 4 is located in the inspection area to inspect the workpiece 9 after press forming. The transfer frame 5 is used to carry the workpiece 9 unloaded from the unloading area. Multiple transfer devices 6 are respectively located between multiple partitions for the transfer of workpiece 9 between two adjacent partitions. By selecting different stamping dies, the workpiece 9 passes through the corresponding devices in the loading area, the centering area, the press forming area, the inspection area, and the unloading area in sequence to complete different stamping processes.

[0055] In the technical solution of this invention, workpiece 9 is mounted on the loading trolley 1 via the rotating material frame, and the workpiece 9 is moved to the loading area via the loading trolley 1. Then, the workpiece 9 is transferred to the centering area for centering and positioning via the transfer device 6, and then transferred to the press forming area for stamping and forming via the transfer device 6. After stamping, the workpiece 9 is transferred to the unloading area via the transfer device 6 after passing through the inspection area, and collected in the transfer material frame 5 in the unloading area, so that it can be used for subsequent stamping after the single press 3 changes the stamping die. By setting the transfer device 6, the workpiece 9 can complete one stamping process. The workpiece 9 after completing one stamping process is transferred to the loading area via the loading trolley 1, so that it can be used for a second stamping process after the single press 3 changes the stamping die. The process is repeated according to the processing steps of the workpiece 9 to complete the processing of the workpiece 9. In this way, the entire cycle processing can be completed by the transfer device 6 and the loading trolley 1 without manual transfer, thereby solving the problem of difficult manual handling of existing single presses.

[0056] To facilitate the positioning of workpiece 9 on the loading trolley 1, in this embodiment, please refer to... Figure 2 The loading trolley 1 includes a trolley platform 11, with multiple insertion holes 111 at the edge of the trolley platform 11. Each insertion hole 111 contains an insertion rod, and the side of each insertion rod is used to abut against the workpiece 9 to limit the workpiece 9. Thus, by setting the insertion rods, the workpiece 9 is positioned on the loading trolley 1. ; and / or,

[0057] Furthermore, a positioning pin is provided on one of the trolley platform 11 and the transfer frame 5, and a positioning hole is provided on the other. The positioning pin is inserted into the positioning hole to cooperate. In this way, the positioning pin and the positioning hole cooperate to position the transfer frame 5 on the trolley platform 11, so as to prevent the transfer frame 5 from disengaging from the loading trolley 1 when the transfer frame 5 moves.

[0058] To prevent workpiece 9 from being contaminated during alignment, please refer to the following in this embodiment. Figure 3 The centering platform 21 is provided with a plurality of support columns 22, which are distributed to correspond to the first preset support points on the workpiece 9. In this way, by setting a plurality of support columns 22, the workpiece 9 is supported and isolated from the centering platform 21 to prevent the workpiece 9 from directly contacting the centering platform 21, thereby preventing the workpiece 9 from being contaminated during centering.

[0059] Since the stamped workpiece 9 has various shapes, and the support positions differ for different shapes of workpiece 9, in this embodiment, please refer to... Figure 4 The centering platform 21 is provided with a plurality of support frames 23, which are distributed to correspond to the second preset support points on the workpiece 9. At least some of the support frames 23 are set with different heights to adapt to the shape of the workpiece 9. In this way, by setting the support frames 23, the centering platform 21 can be adapted to the shape of the workpiece 9, thereby enabling the centering platform 21 to support workpieces 9 with different shapes.

[0060] In order to facilitate the control of the position of workpiece 9, in this embodiment, the single press automated production system 100 also includes a vision alignment system 24 disposed above the alignment platform 21. Thus, by setting the vision alignment system 24, the position of workpiece 9 on the alignment platform 21 can be determined, which is beneficial for the rotating device to accurately transfer workpiece 9 to the alignment platform 21.

[0061] It should be noted that the aforementioned related technical features, such as "multiple support columns 22 are provided on the centering platform 21", "multiple support frames 23 are provided on the centering platform 21", and "the single press automated production system 100 also includes a visual centering system 24 provided above the centering platform 21", can be set individually or simultaneously. Obviously, setting them simultaneously will have a better effect.

[0062] To improve the safety of the single-press automated production system 100, in one embodiment, multiple zones are spaced apart in the left-right direction, and two loading trolleys 1 are spaced apart in the front-back direction. The single-press automated production system 100 also includes safety light curtains 7, with two safety light curtains 7 corresponding to each loading trolley 1, and the two safety light curtains 7 are spaced apart in the front-back direction. When the transfer device 6 retrieves material from the front loading trolley 1, the left safety light curtain 7 of the front loading trolley 1 is closed and the right safety light curtain 7 is open; the left safety light curtain 7 of the rear loading trolley 1 is open and the right safety light curtain 7 is closed. When the transfer device 6 retrieves material from the rear loading trolley 1, the left safety light curtain 7 of the rear loading trolley 1 is closed and the right safety light curtain 7 is open, and the left safety light curtain 7 of the front loading trolley 1 is open and the right safety light curtain 7 is closed. In this way, the two spaced-apart safety light curtains 7 prevent personnel from entering the loading area to avoid danger. It is understood that the single-press automated production system 100 also includes a control device electrically connected to the safety light curtain 7 and an alarm electrically connected to the control device, so that an alarm can be issued in a timely manner when personnel enter the loading area.

[0063] In another embodiment, an isolation fence is provided between the two loading trolleys 1, so as to prevent personnel from entering the area of ​​the other loading trolley 1 when the right safety light curtain 7 of one loading trolley 1 is closed.

[0064] Furthermore, the plurality of transfer devices include transfer robots 61, and multiple transfer robots 61 are provided. The transfer robots 61 are located between the loading area and the centering area, between the centering area and the pressing and forming area, and between the inspection area and the unloading area. Thus, by providing the transfer robots 61 between the loading area and the centering area, the workpiece 9 is transferred from the loading area to the forming area. By providing the transfer robots 61 between the centering area and the pressing and forming area, the workpiece 9 is transferred from the centering area to the pressing and forming area. At the same time, by providing the transfer robots 61 between the inspection area and the unloading area, the processed workpiece 9 is placed in the transfer frame 5.

[0065] In order to transfer the workpiece 9 from the press-forming area to the unloading area, in this embodiment, the multiple transfer devices include a belt conveyor 62. The belt conveyor 62 includes a conveyor belt, and the conveyor belt passes through the press-forming area and the inspection area in sequence. In this way, by setting the belt conveyor 62, the processed workpiece 9 can be transferred from the press-forming area to the unloading area for unloading, and the travel distance of the workpiece 9 can be increased so that the workpiece 9 can be inspected during the movement of the workpiece 9.

[0066] Furthermore, a transfer robot 61 is provided between the feeding end of the conveyor belt and the pressing and forming area to transfer the processed workpiece 9 from the single press 3 to the conveyor belt, so that the conveyor belt can transfer the workpiece 9 to the unloading area.

[0067] To inspect the processed workpiece 9, in this embodiment, the single-press automated production system 100 further includes an off-line inspection device. This off-line inspection device includes an off-line inspection table located on one side of the conveyor belt. By setting up this off-line inspection device to inspect the workpiece 9 on the conveyor belt, defective workpieces 9 can be screened out to prevent them from entering subsequent processes, thus improving both the product pass rate and processing efficiency. Furthermore, the inspection device 4 includes a vision inspection system. By setting up this vision inspection system, appearance defects in the workpiece 9 can be observed, thereby facilitating the rapid screening of defective products.

[0068] To classify the workpieces 9 in the unloading area, in this embodiment, the unloading area includes a scrap station and a collection station. The single-press automated production system 100 also includes a scrap collection frame 8 located at the scrap station, and a transfer frame 5 located at the collection station. Thus, by setting up the scrap station and the collection station, the workpieces 9 are classified. Simultaneously, the scrap collection frame 8 collects defective workpieces 9 for subsequent centralized processing. Furthermore, multiple collection stations are provided, so that when the transfer frame 5 at one of the collection stations is transferring workpieces, the transfer frames 5 at the remaining collection stations can hold the workpieces 9, reducing waiting time and thus improving production efficiency.

[0069] Based on the above hardware structure, this invention proposes an automated production method for a single press, wherein the automated production method for a single press enables the single press to complete the processing of workpiece 9 through cyclic stamping.

[0070] Please see Figure 6 , Figure 6 This is a schematic flowchart of an embodiment of the automated production method for a single press provided by the present invention.

[0071] Different stamping processes include multiple pre-stamping processes and a final stamping process;

[0072] The automated production method for a single press includes the following steps:

[0073] S10: Initial mold installation: Install the stamping mold corresponding to the foremost stamping process.

[0074] S20: Single stamping: The material is processed sequentially through the corresponding devices in the feeding area, the centering area, the press forming area, the inspection area, and the unloading area.

[0075] S30: Single return transport: Transferring the processed workpiece 9 from the unloading area to the loading area;

[0076] S40: Die replacement: Replace the stamping die corresponding to the previous stamping process with the stamping die corresponding to the next stamping process;

[0077] S50: Cyclic stamping: Repeat the above steps of single stamping, single return, and die replacement in sequence until the final stamping process is completed;

[0078] S60: Material storage: Transfer the workpiece 9 after the final stamping process is completed to the warehouse for storage.

[0079] In this embodiment, after workpiece 9 completes one stamping, the stamping die for the next process is replaced and stamping is performed again. In this way, the number of cycles of workpiece 9 is determined according to the processing steps of workpiece 9, so that workpiece 9 can be processed by cyclic stamping, thereby enabling a single press to complete the processing of workpiece 9.

[0080] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
