Description

Technical Field

[0002] The present invention belongs to the technical field of stamping processing equipment, and particularly relates to a PCI-E pin stamping and forming equipment based on machine vision adjustment.

Background Art

[0004] In the process of inserting a PCI-E pin row into the notch of a plastic body, due to the small size of the pins and the use of reverse hooks or interference fits to prevent loosening, each pin in the pin row requires high positional accuracy during production. The conventional production method is to cut off the pin rows with unqualified positional accuracy to achieve the continuity of the next process, which will relatively generate unnecessary waste. Therefore, the stamping process is used for forming.

[0005] However, the PCI-E pins may be deformed after stamping and forming. At the same time, the friction generated during the feeding process and the wear of the pressing deformation will cause errors in the positional accuracy of each pin in the pin row during production. Generally, after the first step of stamping, the next step is to perform detection, and after the detection, the errors are adjusted. However, there are differences in accuracy in the detected values. The adjustment of the workpiece positional accuracy obtained from the error accuracy detected in the prior art still fails to meet the requirements of the PCI-E pin positional accuracy.

[0006] In addition, the conventional feeding method for pin rows uses a tooth meshing transmission method similar to chain drive for feeding. However, due to the extremely small size of PCI-E pins, using a tooth meshing transmission method similar to chain drive for feeding easily causes pin deformation and generates waste.

Detailed Embodiments

[0031] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the following further details the present invention in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] When the embodiments of the present invention mention ordinal numbers such as "first" and "second", unless they actually express an order meaning according to the context, they should be understood as merely for distinction.

[0033] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Such as Figures 1 to 4As shown, the PCI-E pin stamping and forming equipment based on machine vision adjustment includes a servo-controlled feeding mechanism 1 for conveying workpieces. On one side of the servo-controlled feeding mechanism 1, there is a stamping mechanism 2 for receiving workpieces and performing stamping and forming on them. On the other side of the stamping mechanism 2, there is a machine vision inspection mechanism 3 for measuring the errors of the stamped and formed workpieces. The machine vision inspection mechanism 3 detects the total stroke deviation amount equivalent to the amplified error of the workpiece from the first stamping to the workpiece being sent to the machine vision inspection mechanism 3, and then feeds it back to the servo-controlled feeding mechanism 1. The PCI-E pin workpieces are fed step by step by the servo-controlled feeding mechanism 1. Theoretically, each operation of the servo-controlled feeding mechanism 1 makes the displacement of the workpiece a single-cycle stroke y, that is, the theoretical operating stroke of the servo-controlled feeding mechanism 1 from the first station of the stamping mechanism 2 to the workpiece being sent out of the stamping mechanism 2 is an integer multiple of y. The actual displacement of the workpiece per operation of the servo-controlled feeding mechanism 1 is a single-cycle stroke y'. Then the total stroke deviation is an integer multiple of y' - y. Assuming that the number of steps required for the workpiece to travel from the start of the first stamping to being sent out of the stamping mechanism 2 for inspection is n, the total stroke deviation amount of the machine vision inspection pins is n(y' - y). By this method, the deviation amount is amplified and fed back to the servo motor 32, making the adjustment of the single-cycle number of steps of the servo motor 32 more accurate and the single-cycle stroke of the adjusted servo motor 32 more precise. After each trimming, precise processing of subsequent pins can be achieved.

[0035] Further, for the PCI-E pin stamping and forming equipment based on machine vision adjustment, the stamping mechanism 2 includes a stamping mechanism bracket 4. On the stamping mechanism bracket 4, there is a die base 5. Above the die base 5, there is a die pressing bottom plate 6 for die pressing. Above the die pressing bottom plate 6, there is a punch bottom plate 7 for installing a punch die. On the die base 5, there is a feeding guide block 8 for receiving and guiding the workpiece. Along the feeding direction on one side of the feeding guide block 8, there are successively a left reverse hook blanking station 9, a right reverse hook blanking station 10, a flattening profile blanking station 11, and a punching and bending station 12. On the other side of the punching and bending station 12, there is a discharging guide block 13 located on the die base 5 for guiding the discharged and formed workpiece. The workpiece is received by the feeding guide block 8 and then successively conveyed to the left and right reverse hook stations, the flattening profile punching station, and the punching and bending station to complete the filling, and then conveyed to the discharging guide block and sent to the inspection mechanism for inspection.

[0036] Furthermore, the left reverse hook blanking station 9 includes a left reverse hook female die 14 disposed on the female die base 5 near the feeding guide block 8. A left reverse hook pressure block 18 is provided on the left reverse hook female die 14. The left reverse hook female die 14 and the left reverse hook pressure block 18 are located between the female die base 5 and the die pressing bottom plate 6. Above the left reverse hook pressure block 18, there is a left reverse hook punching knife 21 connected to the die punching bottom plate 7 and passing through the die pressing bottom plate 6, the left reverse hook pressure block 18, and the left reverse hook female die 14. The right reverse hook blanking station 10 includes a right reverse hook female die 15 disposed on the female die base 5 near the left reverse hook female die 14. A right reverse hook pressure block 19 is provided on the right reverse hook female die 15. The right reverse hook female die 15 and the right reverse hook pressure block 19 are located between the female die base 5 and the die pressing bottom plate 6. Above the right reverse hook pressure block 19, there is a right reverse hook punching knife 22 connected to the die punching bottom plate 7 and passing through the die pressing bottom plate 6, the right reverse hook pressure block 19, and the right reverse hook female die 15. Both the left reverse hook female die 14 and the right reverse hook female die 15 adopt reverse hook combined female dies, and both the left reverse hook pressure block 18 and the right reverse hook pressure block 19 adopt reverse hook combined pressure blocks. The upper and lower pressing dies adopt a combined die method to ensure that the workpiece can be processed by a simple machining method without the need for drilling and wire cutting processing methods, so as to ensure the surface roughness, manufacturing accuracy of the workpiece and reduce the processing cost.

[0037] Specifically, the flattening profile blanking station 11 includes a profiling female die 16 disposed on the female die base 5 on one side near the right reverse hook female die 15. A profiling pressure block 20 is provided on the profiling female die 16. The profiling female die 16 and the profiling pressure block 20 are located between the female die base 5 and the die pressing bottom plate 6. On the profiling pressure block 20, there is a profiling knife 23 connected to the die punching bottom plate 7 and passing through the die pressing bottom plate 6, the profiling pressure block 20, and the profiling female die 16. After the left and right reverse hooks of the workpiece are punched out, it is transported to the flattening profile blanking station 11 to flatten the workpiece profile and punch out the waste.

[0038] More specifically, the punching and bending station 12 includes a punching and bending lower die 17 disposed on the female die base 5 on one side near the profiling female die 16. Above the punching and bending lower die 17, there is a punching and bending knife 24 connected to the die punching bottom plate 7 and passing through the die pressing bottom plate 6. After the workpiece passes through the flattening profile blanking station 11, it enters the punching and bending station 12, and the workpiece with the profile flattened by punching out the waste is punched and bent to finally obtain the PCI-E pin workpiece with the profiling completed.

[0039] Furthermore, a plurality of guide posts 25 are provided on the concave die base 5. The guide posts 25 sequentially penetrate through the pressing die bottom plate 6 and the punching die bottom plate 7. Springs 26 for resetting the die are provided between the concave die base 5 and the pressing die bottom plate 6 and between the pressing die bottom plate 6 and the punching die bottom plate 7. The springs 26 are sleeved on the respective guide posts 25. The upper ends of the guide posts 25 are connected to an upper beam 27, and a cylinder 28 for providing punching force is provided above the upper beam 27. The guide posts 25 guide the reverse hook pressing block and the reverse hook concave die, the punching block 20 and the punching concave die 16, and the punching bending knife 24 and the punching bending lower die 17 to be aligned at the correct positions. Installing the springs 26 on the guide posts can not only reset the die after stamping, but also reduce the punching force during the stamping process, playing a buffering role.

[0040] Still further, the servo-controlled feeding mechanism 1 includes a feeding rack 29 for conveying workpieces, a pressing wheel 30 provided at the upper end of the feeding rack 29 for pressing the workpieces, a driving wheel 31 provided at the lower end of the feeding rack 29 for cooperating with the pressing wheel 30 to convey the workpieces, and a servo motor 32 connected to the driving wheel 31 and controlling the rotation of the driving wheel 31. The servo feeding mechanism 1 feeds the materials in a way of rubber-coated wheel friction, and the friction force is adjusted by cylinder pressure regulation. It can ensure that the raw copper foil is not damaged while ensuring the smooth feeding of the workpieces.

[0041] Finally, the machine vision detection mechanism 3 includes a camera support 33 and a detection camera 34 provided on the camera support 33 for detecting the position deviation of the workpiece before and after stamping and feeding it back to the servo motor 32 for precise adjustment. The CCD camera is used for detection and arranged at the workpiece outlet position to obtain a more accurate deviation amount, which is fed back to the servo motor 32. By adjusting the number of steps of the motor, the single-cycle stroke of the motor is adjusted. After each trimming, the subsequent pins can be precisely processed.

[0042] The present invention provides a PCI-E pin stamping and forming device based on machine vision adjustment. First, a servo-controlled feeding mechanism controls the feeding of the workpiece. The feeding is carried out by the friction of a rubber-coated wheel, and the friction force is adjusted by the air cylinder pressure regulation. The air cylinder pushes the rubber-coated non-powered roller, which presses the rubber-coated powered roller on the motor shaft against the workpiece. This can ensure that the copper foil of the workpiece is not flattened while ensuring the smooth feeding of the workpiece. The workpiece is fed into the stamping mechanism and passes through the left reverse hook blanking station, the right reverse hook blanking station, the flattening contour blanking station, and the bending station in sequence to achieve stamping and forming. Then, the machine vision detection mechanism detects the workpiece after the filling is completed. It is detected that the theoretical running stroke of the motor is an integer multiple of y. From the first station, the left reverse hook blanking station, to the workpiece being sent to the machine vision detection mechanism, the pins at the processed position have experienced n strokes in total. The total stroke deviation amount after magnification of the workpiece from the first stamping to the detection position is detected by the detection mechanism. The magnified total stroke deviation amount is divided by n strokes to obtain the single-cycle stroke deviation amount. Then, the single-cycle stroke deviation amount is fed back to the servo-controlled feeding mechanism to adjust the number of steps of the motor, thereby adjusting the single-cycle stroke of the motor. For example, when the detected value is 0.1 mm, assuming the feeding step number n is 100, after magnifying the error, the adjustment value for the servo motor is 0.001 mm, which improves the position accuracy of the PCI-E pin workpiece during the production process.

[0043] The present invention provides a PCI-E pin stamping and forming device based on machine vision adjustment. The machine vision detection mechanism detects the total stroke deviation amount accumulated by the PCI-E pin workpiece after n strokes from the first stamping to the completion of stamping, thereby magnifying the error value. Only when the magnified error value meets the minimum error detection requirement of the machine vision detection mechanism for the PCI-E pin workpiece can the detection of the vision detection mechanism be more accurate. Then, through calculation, the obtained single-cycle stroke deviation amount is fed back to the servo motor, thereby meeting the position accuracy requirement of the PCI-E pins during the production process and reducing the generation of unnecessary waste. Among them, the feeding process uses the friction method for feeding. By adopting the rubber coating process, the rubber-coated pressure wheel and the rubber-coated power wheel cooperate for feeding, and the friction force is adjusted by the air cylinder pressure regulation, which can ensure that the workpiece is not damaged while increasing the friction force. The upper and lower pressing dies at the reverse hook blanking station adopt a combined die method, ensuring that the workpiece can be processed by simple machining methods without using drilling and wire cutting methods, so as to ensure the surface roughness, manufacturing accuracy of the workpiece and reduce the processing cost.
