Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of industrial automation detection equipment, and particularly to a stamping part integrity detection mechanism based on a photoelectric induction switch. Background Art
[0002] Nowadays, customers' requirements for product quality are becoming increasingly strict. Before products are shipped out, 100% visual marking full inspection is basically required, and for some individual parts, even 200% full inspection is required. Once unqualified parts flow to the subsequent inspection and penalty costs at the customer end are also very high.
[0003] The detection needs to detect the hole positions of stamping parts and the welding of nuts. Most of the existing detections are carried out by manual visual full inspection to detect whether there are missing punched holes, nuts, and bolts that are not welded. The efficiency is relatively low. Therefore, detection tooling has begun to be used for detection. The existing tooling uses detection pins or sensors to perform single-item detections on missing punched holes, missing welding, etc. When multiple detections are required, multiple toolings need to be used for detection separately, resulting in high production costs and low detection efficiency. Moreover, for stamping parts that need to be detected on both sides, a single tooling cannot achieve multi-faceted detection, and the detection efficiency is relatively low. Summary of the Invention
[0004] In view of this, the purpose of the present invention is to provide a stamping part integrity detection mechanism based on a photoelectric induction switch to solve the problem of low detection efficiency caused by the need for multiple toolings to be detected separately.
[0005] Based on the above purpose, the present invention provides a stamping part integrity detection mechanism based on a photoelectric induction switch, including a bottom plate. One end of the bottom plate is fixedly connected with an initial positioning plate. The middle of the bottom plate is respectively provided with a first positioning detection mechanism and a second positioning detection mechanism. The first positioning detection mechanism detects the forward hole positions of stamping parts, and the second positioning detection mechanism detects the reverse nuts of stamping parts. Limit mechanisms are arranged corresponding to the first positioning detection mechanism and the second positioning detection mechanism on the bottom plate, and the limit mechanisms limit the placed stamping parts.
[0006] Further improvement lies in that the first positioning detection mechanism includes a first support block and a side positioning plate installed on the bottom plate. The side positioning plate is located on one side of the first support block. A first photoelectric induction switch and a first positioning pin are installed on the base at one end of the first support block. Detection pins are installed on both the first support block and the bottom plate.
[0007] Further improvement lies in that the second positioning detection mechanism includes four second support blocks arranged in a rectangular array distribution. A second positioning pin is installed in the middle between the second support blocks, and second photoelectric induction switches are installed on both sides between the second support blocks.
[0008] Further improvement lies in that an indicator light is installed at one end of the bottom plate. The indicator light corresponds to the first positioning detection mechanism and the second positioning detection mechanism, and the indicator light gives a reminder according to the detection result.
[0009] Further improvement lies in that the limiting mechanism includes a driving rod and a driven rod. A sliding groove and a rotating groove are formed on the surface of the bottom plate. The rotating groove is arranged on both sides of the sliding groove and communicates with the sliding groove. The driving rod is slidably arranged in the sliding groove, and the driven rod is rotatably installed in the rotating groove through a rotating shaft. The other end of the driven rod is fixedly connected with a limiting rod, and the upper end of the limiting rod is fixedly connected with a pressing plate.
[0010] Further improvement lies in that pushing blocks are fixedly connected to both sides of the driving rod, and one end of the driven rod extends into the sliding groove and abuts against the pushing block.
[0011] Further improvement lies in that a torsion spring is sleeved on the rotating shaft, and both ends of the torsion spring are respectively connected with the driven rod and the inner wall of the rotating groove.
[0012] Further improvement lies in that a limiting groove is formed on the side of one end of the rotating groove, one corresponding end of the driving rod is rotatably connected to a limiting block, a return spring is sleeved and connected to the other end of the driving rod, and the other end of the return spring is connected with the inner wall of the other end of the rotating groove.
[0013] Further improvement lies in that a bracket is fixedly connected to the lower side of the bottom plate, an electrical box is installed on the bracket, and rollers are installed at the lower end of the bracket.
[0014] The beneficial effects of the present invention: By setting the first positioning detection mechanism and the second positioning detection mechanism, both the front and back sides of the stamping part can be detected, making the detection more comprehensive; placing the stamping part face up on the first support block, the side positioning plate and the initial positioning plate perform preliminary positioning on the side and the end, the first positioning pin performs positioning, the detection pin detects the hole position and hole diameter to prevent the generation of missed punching, and the first photoelectric induction switch senses and detects the nuts in the middle to prevent the generation of missed welding and wrong welding of nuts and bolts; placing the four corners of the stamping part face down on the corresponding second support blocks, the second positioning pin performs positioning, and the second photoelectric induction switch senses and detects the nuts on both sides; the indicator light quickly gives a reminder of the detection result, greatly improving the detection effect.
[0015] By setting the limiting mechanism, pulling the driving rod makes the pushing block push the driven rod to rotate, and the limiting rod fits to the side of the stamping part for positioning and clamping as the driven rod rotates, making the placement of the stamping part stable. The pressing plate moves to the upper side of the stamping part and fits with the surface of the stamping part as the limiting rod moves. Pressing and limiting the stamping part ensures the accuracy of the position of the stamping part, reduces the generation of deviation, and ensures the accuracy of the detection result.

[0021] As Figure 1 shown, this embodiment provides a stamping part integrity detection mechanism based on a photoelectric induction switch, including a bottom plate 1. A bracket 24 is fixedly connected to the lower side of the bottom plate 1, and a roller 26 is installed at the lower end of the bracket 24. The bracket 24 and the bottom plate 1 are moved through the roller 26. An electrical box 25 is installed on the bracket 24, and a small contactor, a PLC controller and a power voltage regulator are installed in the electrical box 25, which are prior arts and are not particularly limited here.
[0022] One end of the bottom plate 1 is fixedly connected with an initial positioning plate 2. A first positioning detection mechanism and a second positioning detection mechanism are respectively arranged in the middle of the bottom plate 1. The initial positioning plate 2 is located at the ends of the first positioning detection mechanism and the second positioning detection mechanism to limit the ends of the stamping parts placed on the first positioning detection mechanism and the second positioning detection mechanism.
[0023] As Figure 2 shown, the first positioning detection mechanism detects the forward hole positions and nuts of the stamping parts. The first positioning detection mechanism includes a first support block 3 and a side positioning plate 4 installed on the bottom plate 1. The side positioning plate 4 is located on one side of the first support block 3. A first photoelectric induction switch 5 and a first positioning pin 6 are installed on the base at one end of the first support block 3. Detection pins 7 are installed on both the first support block 3 and the bottom plate 1. The first photoelectric induction switch 5, the first positioning pin 6, and the detection pin 7 are respectively arranged corresponding to the positions of the nut, the positioning hole, and the hole to be detected on the front of the stamping part. One end in the middle of the stamping part is clamped on the first support plate, the first positioning pin 6 performs positioning, the first photoelectric induction switch 5 senses and detects the nut on the front of the stamping part, and the detection pin 7 detects the missing punching holes, the positions of the holes, and the hole diameters.
[0024] As Figure 3As shown, the second positioning and detecting mechanism detects the reverse nut of the stamping part. The second positioning and detecting mechanism includes four second supporting blocks 8 arranged in a rectangular pattern. A second positioning pin 9 is installed in the middle between the second supporting blocks 8, and second photoelectric induction switches 10 are installed on both sides between the second supporting blocks 8. The four corners of the stamping part are respectively placed corresponding to the four second supporting blocks 8. The second positioning pin 9 is inserted into the middle hole of the stamping part for positioning, and the second photoelectric induction switches 10 sense and detect the nuts on both sides of the stamping part.
[0025] As Figure 4 , 5 shown, on the bottom plate 1, limiting mechanisms are provided corresponding to the first positioning and detecting mechanism and the second positioning and detecting mechanism, and the limiting mechanisms limit the placed stamping parts. The limiting mechanism includes a driving rod 12 and a driven rod 13. A sliding groove 14 and a rotating groove 15 are formed on the surface of the bottom plate 1. The rotating groove 15 is arranged on both sides of the sliding groove 14 and communicates with the sliding groove 14. The driving rod 12 is slidably arranged in the sliding groove 14, and the driven rod 13 is rotatably installed in the rotating groove 15 through a rotating shaft 16. The other end of the driven rod 13 is fixedly connected with a limiting rod 17. The limiting rod 17 is a height-adjustable structure, and the upper end of the limiting rod 17 is fixedly connected with a pressing plate 18. Push blocks 19 are fixedly connected to both sides of the driving rod 12. One end of the driven rod 13 extends into the sliding groove 14 and abuts against the push block 19. By pulling the driving rod 12, the push block 19 is used to push the driven rod 13 to rotate. Through the rotation of the driven rod 13, the limiting rod 17 fits against the side of the stamping part for clamping, and the pressing block fits on the surface of the stamping part to limit the height position of the stamping part, ensuring that the stamping part is placed in place and improving the accuracy of detection.
[0026] A limiting groove 21 is formed on the side of one end of the rotating groove 15. One corresponding end of the driving rod 12 is rotatably connected to a limiting block 22. By rotating the limiting block 22 into the limiting groove 21, the position of the driving rod 12 is limited. The other end of the driving rod 12 is sleeved and connected with a return spring 23. The other end of the return spring 23 is connected to the inner wall of the other end of the rotating groove 15. The return spring 23 pulls and resets the driving rod 12 released from the limit. A torsion spring 20 is sleeved on the rotating shaft 16. The two ends of the torsion spring 20 are respectively connected to the driven rod 13 and the inner wall of the rotating groove 15. After the driving rod 12 is reset, the driven rod 13 is driven to rotate and reset by the torsion spring 20.
[0027] One end of the bottom plate 1 is provided with an indicator light 11. There are multiple groups of indicator lights 11, and the multiple groups of indicator lights 11 respectively correspond to the first positioning detection mechanism and the second positioning detection mechanism. The indicator light 11 gives a reminder according to the detection result. The first photoelectric induction switch 5, the second photoelectric induction switch 10, the indicator light 11, the small contactor, and the PLC controller are electrically connected. The first photoelectric induction switch 5 and the second photoelectric induction switch 10 are used to detect and sense the stamping parts in different states respectively. The induction signal is sent to the small contactor, and the PLC controller controls whether the corresponding indicator light 11 flashes and sounds an alarm according to the signal received by the small contactor; when the indicator light 11 flashes and sounds an alarm, it means that the stamping part is a qualified part, otherwise it is an unqualified product.
[0028] During the detection, the stamping part is placed on the first positioning detection mechanism along the initial positioning plate 2 in the forward direction, with one end clamped on the first support block 3. The stamping part is positioned by the first positioning pin 6, and the other holes are sequentially detected by the detection pin 7. If it cannot pass sequentially, there are missing punched holes. After the placement is completed, the driving rod 12 is pulled to drive the driven rod 13 to rotate, so that the limiting rod 17 and the pressing plate 18 limit the stamping part to determine that the stamping part is placed in place. The first photoelectric induction switch 5 senses the nuts and bolts on the forward welding holes of the stamping part, and the indicator light 11 gives a reminder according to the induction information; after the forward detection of the stamping part is completed, the stamping part is flipped and then placed on the second positioning detection mechanism along the initial positioning plate 2. The four corners of the stamping part are placed corresponding to the second support block 8, and the second positioning pin 9 is used for positioning. The limiting mechanism limits the stamping part, and the second photoelectric induction switch 10 senses the nuts and bolts on the forward welding holes of the stamping part, and the indicator light 11 gives a reminder according to the induction information; the stamping part is detected on multiple sides through the first positioning detection mechanism and the second positioning detection mechanism, which improves the comprehensiveness of the detection.
