DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The positioning mechanism 4 includes a tray 401, a limiting frame 402, a connecting seat 403, a positioning seat 404 and a fastening rubber ring 405. The limiting frame 402 is fixed at an equal angle on the tray 401, and a workpiece 5 is placed between the limiting frame 402 and the tray 401, and a non-slip rubber pad is provided on the contact surface between the limiting frame 402 and the workpiece 5; a connecting seat 403 is fixed on the lower end surface of the tray 401, and the connecting seat 403 and the positioning seat 404 are nested, and the positioning seat 404 is fixed to the upper end of the movable cylinder 303; a fastening rubber ring 405 is fixed on the outer side of the positioning seat 404, and the fastening rubber ring 405 and the connecting seat 403 are interference fit; the optical detection probe 807 is electrically connected to the detection host, and the storage module in the detection host collects and stores the collected information; When using the optical detection and collection device, Figure 1-Figure 6As shown, firstly, a suitable pallet 401 is selected for installation according to the size of the workpiece 5. When installing the pallet 401, the installation and positioning of the pallet 401 can be achieved through the nesting effect between the connecting seat 403 and the positioning seat 404. The interference connection between the fastening rubber ring 405 and the connecting seat 403 can achieve the fastening effect between the connecting seat 403 and the positioning seat 404, thereby ensuring the stability of the installation of the pallet 401. After the installation of the pallet 401 is completed, the workpiece 5 to be inspected is placed between the limiting frame 402 and the pallet 401. The limiting effect of the workpiece 5 can be achieved through the effect of the limiting frame 402 and the pallet 401. The effect of the anti-slip rubber pad on the limiting frame 402 can not only ensure the stability of the workpiece 5, but also protect the edge of the workpiece 5 to avoid friction damage between the edge of the workpiece 5 and the limiting frame 402. The adjusting mechanism 8 includes a counterweight 801, a slide bar 802, a cross bar 803, a movable block 804, a connecting rod 805, a mounting plate 806, an optical detection probe 807, a positioning plate 808, a ball bearing 809 and a top rod 810. The counterweight 801 is arranged below the fixed plate 7. The slide bar 802 is fixed symmetrically on the upper end surface of the counterweight 801, and the slide bar 802 is slidably connected to the fixed plate 7. The side of the counterweight 801 is symmetrically fixed with a cross bar 803. The movable block 804 is slidably connected to the cross bar 803. The movable block 804 is rotatably connected to one end of the connecting rod 805. The other end of the connecting rod 805 is rotatably connected to the fixed plate 7. The lower end surface of the movable block 804 is fixed with a mounting plate 806. The lower end surface of the mounting plate 806 is fixed An optical detection probe 807 is fixed, a positioning plate 808 is also fixed on the lower end surface of the mounting plate 806, a rollable ball 809 is installed on the positioning plate 808, a push rod 810 is fixed on the lower end surface of the counterweight block 801, and the lower end surface of the push rod 810 is lower than the lower end surface of the positioning plate 808. The adjustment mechanism 8 is driven downward by the extension of the cylinder 6. When the push rod 810 contacts the tray 401, the counterweight block 801 moves upward relative to the fixed plate 7. With the transmission effect of the connecting rod 805, the positions of the movable block 804, the mounting plate 806, the optical detection probe 807, the positioning plate 808 and the ball 809 can be adjusted until the ball 809 contacts the tray 401 to achieve limit. At this time, the optical detection probe 807 is located above the workpiece 5 for detection; After the installation of artifact 5 is completed, Figure 1-Figure 6As shown, the extension of the control cylinder 6 drives the fixed plate 7 and the adjustment mechanism 8 to move downward. When the push rod 810 contacts the tray 401, the push rod 810 is limited and no longer moves downward. The cylinder 6 continues to extend, so that the fixed plate 7 can move downward relative to the counterweight 801. The sliding guide effect between the slide bar 802 and the fixed plate 7 can ensure the stability of the movement of the fixed plate 7, so that the distance between the fixed plate 7 and the counterweight 801 is reduced. The transmission effect of the connecting rod 805 is used to make the movable block 804 slide on the cross bar 803, so as to adjust the position of the movable block 804. When the movable block 804 moves, the mounting plate 806, the optical detection probe 807, the positioning plate 808 and the ball 809 are synchronously driven to move. When the ball 809 contacts the tray 401, the limiting effect is realized. At this time, the optical detection probe 807 is just located above the workpiece 5 for subsequent detection. A rotating mechanism 3 is fixed on the bottom plate 1, and a positioning mechanism 4 is installed on the rotating mechanism 3, and a workpiece 5 is placed on the positioning mechanism 4; the rotating mechanism 3 includes a circular plate 301, a vertical rod 302, a movable cylinder 303, a spring 304, a pressure sensor 305, a spiral groove 306, a fixed rod 307 and a convex shaft 308, the circular plate 301 is connected to the bottom plate 1 by a bearing, and a vertical rod 302 is fixed on the upper end surface of the circular plate 301, and the vertical rod 302 and the movable cylinder 303 are in sliding connection; the circular plate 301 and the spring One end of the spring 304 is fixed to each other, and the other end of the spring 304 is fixed to the lower end surface of the movable cylinder 303; a pressure sensor 305 is fixed in the movable cylinder 303, and the pressure sensor 305 is located directly above the vertical rod 302, and the pressure sensor 305 is electrically connected to the PLC controller, and a spiral groove 306 is opened on the outer wall of the movable cylinder 303; a fixed rod 307 is fixed to the bottom plate 1, and a convex shaft 308 is fixed to the fixed rod 307, and the convex shaft 308 and the spiral groove 306 are slidably connected; When the ball 809 contacts the tray 401 to achieve positioning, Figure 1-Figure 6As shown, at this time, the cylinder 6 continues to extend. Since the distance between the fixed plate 7 and the counterweight block 801 is limited, the cylinder 6 continues to extend, so that the push rod 810 generates downward pressure on the pallet 401, so that the movable cylinder 303 is forced to move downward relative to the circular plate 301, and the sliding guide effect between the movable cylinder 303 and the vertical rod 302 can ensure the stability of the movement of the movable cylinder 303. When the movable cylinder 303 moves, the sliding effect between the convex shaft 308 and the spiral groove 306 is cooperated, so that the movable cylinder 303, the vertical rod 302 and the circular plate 301 are forced to rotate synchronously, thereby driving the pallet 401 and the workpiece 5 to rotate. Through the rotation of the workpiece 5, the optical detection probe 807 can be convenient for a comprehensive detection of the workpiece 5, and the detection data is transmitted to the storage module in the detection host for collection and storage for the staff to view, and the movable cylinder 303 and the vertical rod 302 slide. When the vertical rod 302 contacts the pressure sensor 305 and generates pressure, the pressure sensor 305 transmits a signal to the PLC controller, thereby controlling the cylinder 6 to stop extending and completing the detection. At this time, the cylinder 6 contracts and drives the device to reset. When the push rod 810 no longer generates pressure on the tray 401, the movable cylinder 303 can be reset through the elastic action of the spring 304. At this time, the cylinder 6 continues to contract, and through the gravity of the counterweight block 801, the fixed plate 7 moves upward relative to the counterweight block 801, thereby resetting the mounting plate 806, the optical detection probe 807, the positioning plate 808 and the ball 809. After the mounting plate 806, the optical detection probe 807, the positioning plate 808 and the ball 809 are reset, the cylinder 6 continues to contract, which can separate and reset the push rod 810 to the tray 401 for the next detection. This is the working principle of the optical detection and acquisition device.
