[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] Figure 1 , Figure 2 , Figure 3 and Figure 4 The optical measurement and control device for stamping and forming equipment of automotive seat belt parts shown includes a main frame 1. The main frame 1 has a lower mold base 2 with a lower mold mounted on the upper end and an upper mold base 3 with an upper mold mounted on the lower end installed inside. The lower mold base 2 has an electrically controlled control frame 4 on both sides and an optical detection module 5 installed at the end of the electrically controlled control frame 4.

[0025] To facilitate installation and translation adjustment, lateral adjustment grooves are symmetrically provided on both sides of the lower mold base 2, and transverse adjustment grooves are provided on the inner side of the lateral adjustment grooves. Electrically controlled translation guide rails are installed inside the transverse adjustment grooves.

[0026] The electrically controlled translation guide rail includes an embedded movable guide rail installed in the transverse adjustment groove, an embedded lead screw installed inside the embedded movable guide rail, and an embedded movable internal thread mounting block threaded onto the embedded lead screw.

[0027] To facilitate electronic adjustment, the electronically controlled control frame 4 includes an embedded lifting guide rail 41 mounted on an electronically controlled translation guide rail, an electronically controlled lifting screw 42 mounted inside the embedded lifting guide rail 41, an internal lifting frame 43 with an internally threaded adjusting block on the side wall, an external flipping guide rail 44 hinged to the outside of the internal lifting frame 43, an inner adjusting support rod 45 for controlling the external flipping guide rail 44, a telescopic guide rail 46 mounted inside the external flipping guide rail 44, a lateral translation screw 47 for controlling the telescopic guide rail 46, an adjusting screw 48 mounted inside the telescopic guide rail 46, an internally threaded translation block 49 threaded onto the adjusting screw 48, a first locking claw 50, and a second locking claw 51.

[0028] The electrically controlled lifting screw 42 rotates, thereby driving the internal lifting frame 43 to adjust its height along the embedded lifting guide rail 41. Then, the inner adjusting support rod 45 extends and retracts to control the external flipping guide rail 44 to flip and adjust its height. Then, the lateral translation screw 47 rotates, thereby driving the telescopic guide rail 46 to extend and translate within the external flipping guide rail 44. Then, the adjusting screw 48 rotates, driving the internal threaded translation block 49 to move along the telescopic guide rail 46, thereby driving the second locking claw 51 to squeeze and limit from the outer end, limiting the bottom of the component or finished product. The embedded lifting guide rail 41 is horizontally adjusted along the electrically controlled translation guide rail, thereby controlling the first locking claw 50 to limit the outer side of the component or finished product from the outside.

[0029] To facilitate bidirectional optical inspection, the optical inspection module 5 includes an upper optical probe 51 fixed to the upper end of the internal thread translation block 49 and a lower optical probe 52 fixed to the lower end of the internal thread translation block 49.

[0030] After the electrically controlled control frame 4 is raised to the specified height, it is then electrically flipped and moved to be level with the upper surface of the lower mold base 2. At this time, the electrically controlled control frame 4 is horizontally adjusted, and then the upper optical probe 51 performs an upward optical scan to scan the internal state of the upper mold. At the same time, the lower optical probe 52 performs a downward optical scan to scan the surface state of the stamped workpiece. At the same time, an end optical probe is also installed at the end of the telescopic guide rail 46, which can scan and locate the position of the lower mold and perform optical scans on the lower mold to determine whether there is deformation or damage on its surface.

[0031] To facilitate limiting different positions, the first locking claw 50 is fixed to one side of the bottom of the outer flip guide rail 44, and the second locking claw 51 is fixed to one side of the bottom of the internal thread translation block 49.

[0032] To facilitate the control of the movable connection, one end of the inner adjusting support rod 45 is hinged to the outside of the inner lifting frame 43, and the other end of the inner adjusting support rod 45 is movably connected to the inner side of the outer flip guide rail 44.

[0033] To facilitate translation, the upper surface of the lower mold base 2 is provided with a guide transition groove 21 that cooperates with the first locking claw 50 and the second locking claw 51.

[0034] The guide transition groove 21 allows the first locking claw 50 and the second locking claw 51 to be easily inserted below the edge of the finished product during translation.

[0035] To facilitate lateral lead screw control, the external flip guide rail 44 has symmetrical strip-shaped translation slots on both sides, the lateral translation lead screw 47 is installed inside the strip-shaped translation slots, and the telescopic guide rail 46 has internal thread blocks 461 protruding into the strip-shaped translation slots on both sides.

[0036] The lateral translation screw 47 rotates, thereby driving the internal thread translation block 461 to move and adjust along the strip translation opening, controlling the telescopic guide rail 46 to move and adjust inside the external flip guide rail 44.

[0037] In order to facilitate the support and separation of raw materials and finished products during loading and unloading, electrically controlled translational support frames 6 are symmetrically installed on both sides of the lower mold base 2.

[0038] When the electrically controlled translation support frame 6 at the feeding end moves outward, the electrically controlled control frame 4 clamps the raw material from both sides, then controls the raw material to be lifted, flipped, and translated to the stamping position. When unloading, the electrically controlled control frame 4 clamps the raw material from both sides, then controls the product to move, flip, and descend to the unloading position. Then, when the electrically controlled translation support frame 6 at the unloading end moves outward, it facilitates the separation and unloading by the external unloading robot.

[0039] To facilitate the electrically controlled translation adjustment, the electrically controlled translation support frame 6 includes an L-shaped translation base frame 61 and a bottom adjustment strut 62 for controlling the translation base frame 61.

[0040] The bottom adjustment support rod 62 is fixedly installed inside the lower mold base 2. It is adjusted by telescopic adjustment of the sliding bottom frame 61. In order to reduce the bottom friction, a bottom support wheel is installed at the lower end of the sliding bottom frame 61.

[0041] (I) Working Principle The equipment uses the main frame 1 as the installation base. The lower mold and upper mold are supported by the lower mold base 2 and the upper mold base 3 respectively. The core of the equipment is to achieve dual functions through the electronically controlled frame 4 on both sides of the lower mold base 2: First, it drives the optical detection module 5 at the end to perform multi-directional optical scanning on the lower mold (on the lower mold base 2), the upper mold (on the upper mold base 3) and the stamped finished product, so as to accurately obtain the mold deformation, damage and finished product size data and improve the detection accuracy. Second, through the translation, lifting, flipping and extension of the electronically controlled frame 4, the equipment completes the feeding of stamping raw materials and the unloading of finished products. The scanning of the optical detection module 5 is triggered simultaneously during the feeding and unloading process, without the need for additional detection procedures. At the same time, the electronically controlled translation support frame 6 works with the electronically controlled frame 4 to realize the support separation of raw materials and finished products. The first locking claw 50 and the second locking claw 51 ensure the structural stability of raw materials and finished products during the movement by squeezing and limiting. The whole system adopts the control method of "fitting when idle and acting when busy" and does not occupy additional external space.

[0042] (II) Work Process 1. Material preparation: In the electrically controlled translation support frames 6 on both sides of the lower mold base 2, the bottom adjusting support rod 62 extends and pushes the L-shaped translation base frame 61 outward to make room for raw material conveying; at the same time, the electrically controlled translation guide rail in the transverse adjusting groove in the side adjusting groove of the lower mold base 2 is activated, driving the entire electrically controlled control frame 4 to translate in the direction of the raw material. 2. Raw material clamping and positioning: In the electrically controlled control frame 4, the electrically controlled lifting screw 42 inside the embedded lifting guide rail 41 rotates, driving the internal lifting frame 43 to descend to a height suitable for the raw material; the inner adjusting support rod 45 extends and retracts to control the external flipping guide rail 44 to flip to a horizontal state, so that the first locking claw 50 at the bottom of the external flipping guide rail 44 aligns with the outside of the raw material; subsequently, the lateral translation screw 47 rotates within the strip-shaped translation opening of the external flipping guide rail 44, driving the telescopic guide rail 46 to extend towards the raw material, and the adjusting screw 48 rotates synchronously to drive the internal thread translation block 49 to move, so that the second locking claw 51 at the bottom of the internal thread translation block 49 engages with the first locking claw 50, squeezing and limiting the raw material from the outside and bottom, while the first locking claw 50 and the second locking claw 51 move along the guide transition groove 21 on the lower mold base 2 to ensure stable clamping. 3. Synchronous optical inspection: During the raw material clamping process, the optical inspection module 5 at the end of the electrically controlled control frame 4 is activated. The upper optical probe 51 at the upper end of the internal thread translation block 49 scans upwards at the upper mold at the lower end of the upper mold base 3 to detect its internal state; the lower optical probe 52 at the lower end of the internal thread translation block 49 pre-scans downwards to detect the state of the raw material; the end optical probe at the end of the telescopic guide rail 46 scans the lower mold on the lower mold base 2 to determine whether there is deformation or damage on its surface. The detection data is fed back in real time to confirm whether the mold is suitable. 4. Raw material conveying and stamping: After the detection is confirmed to be correct, the electrically controlled translation guide rail drives the electrically controlled control frame 4 and the clamped raw material to move upwards above the lower mold. The embedded lifting guide rail 41 drives the internal lifting frame 43 to descend, accurately placing the raw material on the lower mold; then, the first locking claw 50 and the second locking claw 51 are released, the electrically controlled control frame 4 returns to both sides of the lower mold base 2, the upper mold base 3 drives the upper mold to descend, and cooperates with the lower mold to complete the stamping of the raw material. 5. Finished product unloading and secondary inspection: After stamping, the upper die holder 3 drives the upper die to rise and reset; the electrically controlled control frame 4 starts again, and according to the above clamping action process, the first locking claw 50 and the second locking claw 51 cooperate to clamp the stamped finished product; during the clamping process, the optical detection module 5 starts again, and the upper optical probe 51, the lower optical probe 52 and the end optical probe scan the upper die, the finished product and the lower die for the second time to confirm whether the finished product size is qualified and whether the die is intact; after the inspection is qualified, the electrically controlled control frame 4 drives the finished product to move in the unloading direction, the bottom adjusting support rod 62 of the electrically controlled translation support frame 6 retracts and pulls the translation bottom frame 61 to reset, and the external unloading robot takes away the finished product from above the translation bottom frame 61, completing a complete stamping and measurement and control cycle.
