[0028] Embodiment 1

[0029] like Figure 1-Figure 4As shown, the intelligent detection equipment for sheet metal forming production line proposed by the present invention includes a base 1, a slider 4, a rack 12, a hollow rod 14, a spacing adjustment component and a side plate 22. A conveyor belt 2 is arranged on the base 1, and a U-shaped frame 3 is arranged on the base 1. The two side support arms of the U-shaped frame 3 are respectively located on the two sides of the conveyor belt 2. The slider 4 is symmetrically and slidably arranged on the U-shaped frame 3. The U-shaped frame 3 is provided with a lifting drive member for driving the sliders 4 on both sides to rise and fall synchronously. The lifting drive member includes but is not limited to a linear module A5. A slide groove 301 is arranged on the U-shaped frame 3. The slider 4 is located in the slide groove 301 on the corresponding side and is slidably connected thereto. The linear module A5 is arranged in the slide groove 301, and the output end of the linear module A5 is connected to the slider 4. The slider 4 is rotatably connected to the hollow shaft 6. A spline shaft 7 is coaxially arranged inside the hollow shaft 6 and slides along its radial direction. The spline shafts 7 on both sides are connected to a clamping plate 8 at the ends close to each other. The hollow shaft 6 is coaxially connected to a worm wheel 9. The slider 4 is rotatably connected to a worm 10. The worm 10 is meshed with the worm wheel 9. The worm 10 is coaxially connected to a gear 11. Two racks 12 are respectively connected to the corresponding side support arms of the U-shaped frame 3, and the gears 11 on both sides are meshed with the racks 12 on the corresponding side when following the slider 4 to lift the height. A circular ring 13 is coaxially arranged on the spline shaft 7 and rotatably connected to the spline shaft 7. The circular ring 13 is rotatably connected to the clamping plate 8 on the corresponding side. A hollow rod 14 is connected to the circular ring 13. The top ends of the hollow rods 14 on both sides are connected to the same group of telescopic rods. The telescopic rods include a cross bar 19 and a slide bar 21. A limit rod 18 is provided on the cross arm of the U-shaped frame 3 and is slidably connected to the limit rod 18. The cross bar 19 is connected to the limit rod 18. Two slide bars 21 are respectively inserted into the corresponding ends of the cross bar 19 and slidably connected to the inner wall thereof, and the ends of the slide bars 21 on both sides that are away from each other are respectively connected to the hollow bars 14 on the corresponding sides, and a detection probe A20 is set at the bottom of the cross bar 19, and the detection probe A20 includes but is not limited to a visual camera A. The spacing adjustment component is connected to the U-shaped frame 3 and drives the hollow bars 14 on both sides to move away or closer synchronously. The side plate 22 is connected to the base 1, and the two side plates 22 are respectively located on both sides of the conveyor belt 2, and a group of detection probes B23 are respectively set at the ends of the side plates 22 on both sides that are close to each other, and the detection probes B23 include but are not limited to visual cameras B. A controller is set on the base 1, and a touch screen is set on the base 1, and the controller is electrically connected to the detection probes A20 and B23. Status indicator lights are set on the U-shaped frame 3 and the side plate 22, and the controller is electrically connected to the status indicator lights. An infrared grating 24 is set on the side plate 22 between the U-shaped frame 3 and the detection probe B23, and the infrared grating 24 is electrically connected to the controller. The side plates 22 on both sides are slidably connected to the same movable plate 25 at the same time. The side plates 22 on both sides are provided with linear modules B26 , and the linear modules B26 on both sides drive the movable plate 25 to slide at the same time.Two blocking plates 27 slidably connected to the bottom of the movable plate 25 are symmetrically arranged, a pressure sensor 28 is arranged on one side of the blocking plate 27 close to the U-shaped frame 3, the pressure sensor 28 is electrically connected to the controller, and a bidirectional module B29 is arranged at the bottom of the movable plate 25 to drive the blocking plate 27 to slide.

[0030] In this embodiment, the conveyor belt 2 conveys the formed sheet metal parts. Different sheet metal parts to be inspected have different widths. In order to make the center position of the clamping plate 8 as close to the side center of the sheet metal part as possible, the linear module B26 is started at this time, and the movable plate 25 is driven to slide by the linear module B26, so that the distance between the blocking plate 27 and the center of the clamping plate 8 is adjusted (the set spacing is equal to half the width of the sheet metal part). When the sheet metal part is conveyed to the contact pressure sensor 28, the pressure sensor 28 generates an electrical signal, and the electrical signal is fed back to the controller. The controller automatically controls the linear module A5 and the bidirectional module A17 to operate, and starts the detection program. When the detection process is started, the bidirectional module B29 drives the blocking plates 27 on both sides to move away from each other, and the bidirectional module A17 drives the inner rods 15 on both sides to move closer to each other, and then drives the clamping plates 8 on both sides to move closer to each other through the hollow rod 14. After the clamping plates 8 on both sides clamp the sheet metal part, the linear module A5 is started. The linear module A5 drives the slider 4 to gradually rise, thereby driving the sheet metal to rise to a certain height from the conveyor belt 2. During the lifting process, the detection probe A20 keeps working and detects the current upward side of the sheet metal. When the gear 11 is lifted to engage with the rack 12, as the height of the slider 4 rises, the gear 11 moves along the rack 12 and drives the worm 10 to rotate. The worm 10 drives the worm wheel 9 and the hollow shaft 6 to rotate, thereby driving the spline shaft 7 and the clamping plate 8 to rotate, thereby driving the sheet metal to rotate. The detection probe A20 performs a blind angle detection on the circumference of the rotating sheet metal. After the detection is completed, the linear module A5 drives the slider 4 to lower its height, and the sheet metal adaptively rotates in the opposite direction. After the gear 11 is separated from the rack 12, the clamping plate 8 remains consistent with the initial working state, and the sheet metal falls back on the conveyor belt 2. Then the clamping plates 8 move away from each other. Since the spacing between the blocking plates 27 on both sides is widened, the transportation of the inspected sheet metal will not be hindered. When the sheet metal passes through the infrared grating 24, the detection probe B23 starts automatically, and the two ends of the sheet metal are detected by the detection probes B23 on both sides. If one of the tests fails, the status light will display a red flashing alarm of failure. If both are qualified, the status light will display a permanent green.

[0031] Embodiment 2

[0032] like Figure 5As shown, the present invention proposes an intelligent detection equipment for a sheet metal forming production line. Compared with the first embodiment, a mounting groove is respectively provided on the side where the two side clamps 8 are close to each other, a perspective window is provided at the opening of the mounting groove, and the detection probe B23 is provided in the mounting groove, and the detection ends of the detection probes B23 on both sides are opposite to each other; a mounting plate 30 is provided on the horizontal arm of the U-shaped frame 3 on the side facing the feeding end of the conveyor belt 2, and a height measuring probe 31 is provided at the bottom of the mounting plate 30, and the height measuring probe 31 includes but is not limited to an infrared ranging sensor, and the infrared ranging sensor is electrically connected to the controller.

[0033] In this embodiment, the detection probe B23 is connected to the clamping plate 8 in an integral manner. When the clamping plate 8 is at the maximum spacing, the height of the clamping plate 8 can be pressed down to detect the two ends of the sheet metal by using the detection probes B23 on both sides. In this structure, there is no need to use the infrared grating 24 structure. At the same time, before clamping the sheet metal, the maximum height of the sheet metal is measured by the infrared distance sensor, and the height of the clamping plate 8 is automatically determined according to the measured height. Through this structure, the clamping starting height of the clamping plate 8 can be maintained at the middle waist position of the sheet metal, avoiding the eccentric rotation of the sheet metal when the clamping plate 8 rotates, and effectively preventing the sheet metal from detaching from the clamping plate 8.

[0034] Embodiment 3

[0035] like Figure 6 and Figure 7 As shown, the present invention proposes an intelligent detection device for a sheet metal forming production line. Compared with the first and second embodiments, a support foot 32 is respectively arranged at the bottom of the base 1 below the four bottom corners thereof, and each support foot 32 is respectively provided with a storage groove with an opening facing downward, and a movable rod 33 is arranged in the storage groove to be slidably connected to the inner wall thereof, and the bottom of the movable rod 33 is connected to a universal wheel 34, and a self-locking component is arranged on the universal wheel 34; a group of height adjustment components 35 are respectively arranged on each support foot 32, and the height adjustment component 35 includes a power motor, a worm gear, a screwdriver ... Wheel A and worm A; a screw rod rotatably connected to the supporting foot 32 is arranged in the storage groove of the supporting foot 32, one end of the screw rod is inserted into the movable rod 33 and spirally connected thereto; the worm wheel A is coaxially connected to the screw rod, the worm A is rotatably connected to the supporting foot 32, and the worm A is meshed with the worm wheel A; the body of the power motor is connected to the supporting foot 32, and the output end of the power motor is connected to the worm A; each supporting foot 32 is connected to the same connecting frame 36, and an inclination sensor 37 is arranged on the connecting frame 36, and each power motor and the inclination sensor 37 are connected to the controller.

[0036] In this embodiment, the base 1 is placed on the ground through the support feet 32. After the equipment is powered on, it is visually checked whether all the universal wheels 34 are on the ground. When a universal wheel 34 is suspended in the air, the power motor on the corresponding side is manually started. The power motor drives the worm A to rotate, and then the worm A drives the worm wheel A and the lead screw to rotate, so that the movable rod 33 on this side drives the universal wheel 34 to drop to the ground, and then the inclination sensor 37 automatically detects the horizontal state of the equipment. When the upper surface of the equipment base 1 is in a non-horizontal state, the inclination sensor 37 automatically detects the inclination angle and inclination direction of the equipment, and the controller controls the power motor on the corresponding side to move and automatically adjust the base 1 to a horizontal state. The use of this structure can effectively improve the stability of the equipment and make the sheet metal parts rise and fall vertically.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
