Description

Technical Field

[0001] This invention relates to the field of parts processing technology, and more specifically, to a method for inspecting the processing of stainless steel bright strips. Background Technology

[0002] Stainless steel bright strips are often used in automotive exterior parts. To meet the assembly requirements of different car models, stainless steel bright strips are processed. Due to the inherent errors in the workpiece, it is usually necessary to process both ends of the stainless steel bright strip separately to obtain the final shaped workpiece.

[0003] In related technologies, when processing the two ends of stainless steel bright strips, a separate, sequential processing method is typically used. Furthermore, the finished product is often only inspected after forming is complete, lacking real-time monitoring during the processing. Because the two ends of the bright strip are not processed synchronously, if an error occurs at one end and the process parameters cannot be adjusted in time, continuing to process the other end will lead to the continued circulation of defective products. This will result in the accumulation of errors or the inability to correct them, ultimately causing a decrease in the finished product yield. Summary of the Invention

[0004] The problem addressed by this invention is how to effectively improve the pass rate of finished products.

[0005] To address the above problems, this invention provides a method for inspecting the processing of stainless steel bright strips, comprising the following steps: Process one end of the workpiece; and obtain the length of the workpiece after processing one end; The length of the workpiece after processing at one end is compared with the first preset length. If the length of the workpiece after processing at one end is less than the first preset length, the workpiece is sent into the recycling box. If the length of the workpiece after processing one end is equal to the first preset length, then process the other end of the workpiece. If the length of the workpiece after processing one end is greater than the first preset length, then adjust the processing parameters of the other end of the workpiece according to the length of the workpiece after processing one end and process the other end of the workpiece. The length of the workpiece after processing both ends is obtained and compared with the second preset length. If the length of the workpiece after processing both ends is equal to the second preset length, the workpiece after processing both ends is further processed. If the length of the workpiece after processing both ends is not equal to the second preset length, the workpiece is recycled.

[0006] Optionally, obtaining the length of the workpiece after processing at one end includes: placing the workpiece between two telescopic cylinders spaced a third preset length apart; obtaining the extension length of the telescopic cylinders by extending the two telescopic cylinders to abut against both ends of the workpiece; and obtaining the length of the workpiece after processing at one end by the difference between the third preset length and the extension length of the telescopic cylinders.

[0007] Optionally, processing one end of the workpiece may include stamping the workpiece.

[0008] Optionally, the processing parameters include the punching feed rate.

[0009] Optionally, adjusting the processing parameters of the other end of the workpiece according to the length of the workpiece after processing one end and processing the other end of the workpiece includes: subtracting the obtained length of the workpiece after processing one end from a first preset length to obtain a difference value, obtaining the blanking feed amount when processing the other end of the workpiece according to the difference value, adjusting the distance of the other end of the workpiece entering the equipment according to the blanking feed amount, and processing the other end of the workpiece.

[0010] Optionally, processing one end of the workpiece also includes: gripping the workpiece with a robot arm according to its length and bringing one end into the equipment for processing.

[0011] Optionally, placing the workpiece between two telescopic cylinders spaced a third preset length includes: moving the workpiece between the two telescopic cylinders spaced a third preset length using a robotic arm.

[0012] Optionally, adjusting the processing parameters of the other end of the workpiece according to the length of the workpiece after processing at one end and processing the other end of the workpiece includes: using a robot to grab the workpiece between two telescopic cylinders spaced a third preset length apart, and causing the other end of the workpiece to enter the equipment for processing.

[0013] Optionally, adjusting the processing parameters of the other end of the workpiece according to the length of the workpiece after processing one end and processing the other end of the workpiece further includes: adjusting the position of the robot gripping the workpiece according to the length of the workpiece after processing one end.

[0014] Optionally, adjusting the position of the robot gripping the workpiece according to the obtained length of the workpiece after processing at one end includes: shifting the position of the robot gripping the workpiece towards the processed end of the workpiece by the same distance as the obtained difference.

[0015] The beneficial effects of the stainless steel bright strip processing inspection method of the present invention are: After processing one end of a workpiece, its length changes. The length of the workpiece after processing is obtained, and compared with a first preset length. This effectively determines whether the processed end meets the requirements. If the length is less than the first preset length, the workpiece cannot be lengthened and is directly recycled, avoiding a decrease in the pass rate due to defective products. When the length is the same as the first preset length, the other end can be processed directly. When the length is greater than the first preset length, the processing parameters of the other end can be adjusted based on the length of the processed end, i.e., adjusting the required processing length of the other end to meet a second preset length. The method involves further processing of the first preset length portion to avoid waste of the workpiece. After both ends of the workpiece have been processed, the length of the processed workpiece at both ends is measured again to determine if it meets the processing requirements. If it does, the workpiece is transferred for further processing; otherwise, it is recycled. This method can effectively process workpieces in segments, and the workpiece is inspected after each segment is processed. This effectively prevents workpieces from continuing to circulate due to excessively short length, which would reduce the pass rate and affect processing efficiency. Furthermore, the processing parameters of workpieces that are too long can be adjusted to correct the workpiece length in a timely manner, effectively ensuring the pass rate of the finished product, significantly reducing the number of ineffective processing operations, and reducing the waste of raw materials. The overall production efficiency of the processing flow is significantly improved. Attached Figure Description

[0020] In related technologies, stainless steel bright strips are often used for exterior decorations in automobiles. To meet the assembly requirements of different models, stainless steel bright strips are processed. Due to the inherent errors in the workpiece, it is usually necessary to process both ends of the stainless steel bright strip separately to obtain the final shaped workpiece.

[0021] In related technologies, when processing the two ends of stainless steel bright strips, a separate, sequential processing method is typically used. Furthermore, the finished product is often only inspected after forming is complete, lacking real-time monitoring during the processing. Because the two ends of the bright strip are not processed synchronously, if an error occurs at one end and the process parameters cannot be adjusted in time, continuing to process the other end will lead to the continued circulation of defective products. This will result in the accumulation of errors or the inability to correct them, ultimately causing a decrease in the finished product yield.

[0022] To address the problems existing in the aforementioned related technologies, this embodiment provides a method for detecting the processing of stainless steel bright strips.

[0023] like Figure 1 As shown in the figure, an embodiment of the present invention provides a method for detecting the processing of stainless steel bright strips, which includes the following steps: One end of the workpiece is machined; and the length of the workpiece after machining is obtained. The length of the workpiece after processing at one end is compared with the first preset length. If the length of the workpiece after processing at one end is less than the first preset length, the workpiece is sent into the recycling bin. If the length of the workpiece after processing one end is equal to the first preset length, then the other end of the workpiece is processed. If the length of the workpiece after processing one end is greater than the first preset length, then the processing parameters of the other end of the workpiece are adjusted according to the length of the workpiece after processing one end, and the other end of the workpiece is processed. The length of the workpiece after both ends are processed is obtained and compared with the second preset length. If the length of the workpiece after both ends are processed is equal to the second preset length, the workpiece after both ends are processed is further processed. If the length of the workpiece after both ends are processed is not equal to the second preset length, the workpiece is recycled.

[0024] Specifically, the length of the workpiece changes after processing. The first preset length is the standard length of the workpiece after processing one end, while the second preset length is the standard length of the workpiece after processing both ends. The adjustment of the processing parameters is actually adjusting the parameters of the equipment when processing the workpiece.

[0025] In this embodiment, after processing one end of the workpiece, the length of the workpiece changes. The length of the workpiece after processing one end is obtained and compared with a first preset length. This can effectively determine whether the workpiece at one end meets the requirements. If the length of the workpiece after processing one end is less than the first preset length, the workpiece cannot be lengthened, so it is directly recycled, avoiding a decrease in the pass rate caused by the circulation of defective products. When the length of the workpiece after processing one end is the same as the first preset length, it means that the workpiece at one end can be directly processed at the other end. When the length of the workpiece after processing one end is greater than the first preset length, the processing parameters of the other end can be adjusted according to the length of the workpiece at one end. That is, the length to be processed at the other end of the workpiece is adjusted so that the other end of the workpiece can meet the second preset length after processing. That is, the part with a length greater than the first preset length is subsequently compensated for, avoiding waste of the workpiece. After both ends of the workpiece are processed, the length of the workpiece at both ends is measured again to determine whether it meets the processing requirements. If it meets the processing requirements, the workpiece is transferred to subsequent processing. If it does not meet the requirements, the workpiece is recycled. This method can effectively process workpieces in segments, and inspect the workpiece after each segment is processed. This effectively prevents workpieces from continuing to circulate due to being too short, which would reduce the pass rate and affect processing efficiency. Furthermore, it can adjust the processing parameters of workpieces that are too long, correct the workpiece length in a timely manner, effectively ensure the pass rate of finished products, significantly reduce the number of invalid processing operations, reduce the waste of raw materials, and significantly improve the overall production efficiency of the processing flow.

[0026] Optionally, obtaining the length of the workpiece after processing at one end includes: placing the workpiece between two telescopic cylinders spaced a third preset length apart; obtaining the extension length of the telescopic cylinders by extending the two telescopic cylinders to abut against both ends of the workpiece; and obtaining the length of the workpiece after processing at one end by the difference between the third preset length and the extension length of the telescopic cylinders.

[0027] Specifically, the third preset length is the length between the telescopic ends of the two telescopic cylinders, and the third preset length is greater than the total length of the workpiece. The extension length of the two telescopic cylinders is the displacement distance of the telescopic ends of the telescopic cylinders, which can be measured by tools such as displacement sensors. The extension length of the telescopic cylinders is existing technology and will not be described in detail in this application.

[0028] In this embodiment, the length of the workpiece after one end is processed can be obtained by calculating the distance between the telescopic ends of the two telescopic cylinders and their contact with both ends of the workpiece. The measurement is simple and accurate.

[0029] Optionally, processing one end of the workpiece includes stamping the workpiece.

[0030] In this embodiment, the workpiece is stamped and cut to change its length.

[0031] Optionally, the processing parameters include the punching feed rate.

[0032] In this embodiment, when the length of the workpiece after processing one end is too long, adjusting the punching feed can adjust the length of the other end of the workpiece after processing, so that the length of the workpiece after processing meets the qualified requirements.

[0033] Optionally, adjusting the processing parameters of the other end of the workpiece according to the length of the workpiece after processing at one end and processing the other end of the workpiece includes: obtaining a difference value by subtracting the length of the workpiece after processing at one end from the first preset length, obtaining the blanking feed amount when processing the other end of the workpiece according to the difference value, adjusting the distance of the other end of the workpiece entering the equipment according to the blanking feed amount, and processing the other end of the workpiece.

[0034] In this embodiment, the length of the workpiece after processing one end is reduced by the first preset length to obtain a workpiece length greater than the standard. Based on this length, the length of the workpiece entering the equipment is adjusted. The punching feed of the workpiece entering the equipment is the original length of the other end of the workpiece entering the equipment plus the length of the workpiece greater than the standard. In this way, by controlling the punching feed of the other end of the workpiece, the length of the workpiece after processing at both ends conforms to the second preset length.

[0035] Optionally, processing one end of the workpiece further includes: gripping the workpiece with a robotic arm according to its length and allowing one end of the workpiece to enter the equipment for processing.

[0036] Specifically, the use of robotic arms to grasp workpieces is an existing technology, so the methods used in this application to grasp workpieces will not be described in detail.

[0037] In this embodiment, the workpiece is gripped and processed by a robotic arm, which effectively improves the automation level of workpiece processing and meets the accuracy requirements of workpiece processing.

[0038] Optionally, placing the workpiece between two telescopic cylinders spaced a third preset length includes: moving the workpiece between the two telescopic cylinders spaced a third preset length using the robotic arm.

[0039] In this embodiment, the workpiece is grasped and measured by a robotic arm, which effectively improves the automation level of workpiece processing.

[0040] Optionally, adjusting the processing parameters of the other end of the workpiece according to the length of the workpiece after processing at one end and processing the other end of the workpiece further includes: using the robot to grab the workpiece between two telescopic cylinders spaced apart by the third preset length, and causing the other end of the workpiece to enter the equipment for processing.

[0041] In this embodiment, the workpiece is grasped and measured by a robotic arm, and then placed in a recycling bin or rotated by the robotic arm. After rotation, the other end of the workpiece is processed, which effectively improves the automation level of workpiece processing.

[0042] Optionally, adjusting the processing parameters of the other end of the workpiece according to the length of the workpiece after processing at one end and processing the other end of the workpiece further includes: adjusting the position of the robot gripping the workpiece according to the length of the workpiece after processing at one end.

[0043] In this embodiment, when adjusting the processing length of the other end of the workpiece, the distance at which the robot arm grasps the workpiece and feeds it into the equipment will change. By adjusting the position of the workpiece grasp, the distance between the robot arm and the equipment after the robot arm grasps the workpiece and feeds it in can be effectively adjusted.

[0044] Optionally, adjusting the position of the robot gripping the workpiece according to the obtained length of the workpiece after processing at one end includes: shifting the position of the robot gripping the workpiece towards the processed end of the workpiece by the same distance as the obtained difference.

[0045] In this embodiment, by offsetting the gripping position of the robot arm towards the already processed end by the same distance as the length difference, it can be effectively ensured that after the other end of the workpiece is fully fed into the equipment, the distance between the robot arm and the equipment is the same as the distance when the robot arm feeds the workpiece that meets the first preset length into the equipment. This eliminates the need for additional positioning adjustment procedures for the robot arm and effectively avoids the situation where the robot arm shortens the distance to the equipment without adjusting its position when the workpiece length is too short, thus preventing a collision with the equipment.

[0046] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
