Detailed Implementation
[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
[0020] like Figure 1 As shown, the present invention provides a feeding and detection mechanism for an automotive blanking mold, which is set on the mold body 1. The mold body 1 is equipped with a roller structure. The plate is placed above the mold body 1 for notch stamping. During processing, the distance between two adjacent notches is the same. Therefore, it is necessary to ensure that the plate moves the same distance each time during stamping. The detection mechanism of this solution is used to detect whether the plate moves the same distance each time.
[0021] like Figure 2As shown, the detection mechanism of this solution includes a distance sensing mechanism 2 and a displacement mechanism 3 disposed opposite to the distance sensing mechanism 2. The displacement mechanism 3 includes a mounting plate 31, a fixed base 32 disposed on the mounting plate, and a movable member 34 movably disposed on the fixed base 32. An elastic reset member is disposed between the movable member 34 and the fixed base 32. The movable member 34 faces the plate located on the mold body 1, and one side of the movable member 34 is in abutting contact with the plate, while the other side is opposite to the distance sensing mechanism 2.
[0022] During the movement of the plate, the moving part 34 presses against the plate. When the notch stamped on the plate is opposite to the moving part 34, the moving part 34 moves towards the notch under the action of the elastic reset part. At this time, the distance sensing mechanism 2 corresponding to the moving part 34 detects the distance change and sends a detection signal to the host computer, indicating that the plate's step distance is accurate. Conversely, if the step distance is deviated, the notch will not be opposite to the moving part 34, the moving part 34 will press against the plate and cannot enter the notch. In this case, the distance sensing mechanism 2 will not detect the distance change, and the host computer will not receive the signal. At this time, the surface step distance is incorrect.
[0023] This solution uses the distance sensing mechanism 2 and the displacement mechanism 3 in cooperation to solve the problem of accurate feeding step distance, reduce product defect rate, check whether the board is fed incorrectly or in place, has high detection accuracy, is easy to operate, can detect and stop the machine in time to protect the mold and punch, improve production efficiency and save costs.
[0024] The fixed base 32 is provided with a displacement groove 33, and the moving part 34 is slidably connected to the displacement groove 33. The moving part 34 includes an overall U-shape, including an L-shaped sliding plate 341 and a contact rod 342 integrally formed with the sliding plate 341, and the contact rod 342 contacts the plate. The fixed base 32 is fixedly mounted on the mounting plate 31, which is mounted on the mold body 1. The bottom of the fixed base 32 is provided with a through groove. The vertical part of the L-shaped sliding plate 341 is limited by the displacement groove 33, and the horizontal part passes through the through groove and connects to the contact rod 342 outside the fixed base 32. One side of the contact rod 342 is provided with a bevel 343, which is set with a rounded corner structure. The bevel 343 and the rounded corner allow the contact rod 342 to smoothly enter and exit the notch on the plate when the plate moves, avoiding jamming.
[0025] like Figure 3 As shown, this is the state when the contact rod 342 enters the notch on the plate, as... Figure 4 As shown, this is the state when the contact rod 342 has not entered the notch on the plate. The state of the aforementioned moving member 34 is reset by the elastic reset member.
[0026] The elastic reset component includes a reset spring 35, which is disposed between the fixed base 32 and the contact rod 342, with both ends connected to the fixed base 32 and the contact rod 342 respectively. When the contact rod 342 is not in the notch on the plate, the reset spring 35 is compressed; when the contact rod 342 enters the notch on the plate, the reset spring 35 resets, causing the contact rod 342 to extend into the notch. The displacement change of the aforementioned moving component 34 is detected by the distance sensing mechanism 2.
[0027] The distance sensing mechanism 2 includes a mounting bracket 21 and a distance sensor 22 mounted on the mounting bracket 21. The distance sensor 22 is positioned towards the sliding plate 341. The distance sensor 22 can be a laser distance sensor or similar device from the prior art, as long as it can detect distance changes.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
