[0027] In the following description, many specific details are set forth to facilitate a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive of other embodiments.

[0029] Thirdly, the present invention is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present invention, for the sake of convenience of explanation, the cross-sectional views showing the device structure are locally enlarged not in accordance with the general ratio, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0030] Embodiment 1 Referring to Figures 1-3 , this is the first embodiment of the present invention. This embodiment provides an on-line flatness measuring instrument for foil materials, including a console 1, a detection unit 2 provided on one side of the console 1. The detection unit 2 includes a bracket 21. The bottom side of the bracket 21 is provided with anchor bolts, and the anchor bolts can adjust the parallelism between the detection unit 2 and the foil material. A driving mechanism 22 is installed on the surface of the bracket 21. The driving mechanism 22 can drive the connecting plate 23 to move reciprocally. The output end of the driving mechanism 22 is connected to the connecting plate 23. The driving mechanism 22 is preferably a linear motor. The connecting plate 23 connects three groups of adjustment platforms 24. Two laser probes 25 are installed on each group of adjustment platforms 24. The detection ends of the laser probes 25 face upward. By providing multiple reflection sensors, the output length of the foil material can be reduced. The detection unit 2 is covered with a cover 4.

[0031] Specifically, a moving guide rail 26 is installed on the top side of the bracket 21, and a calibration block 27 is installed on the moving guide rail 26. When adjusting the laser probe 25, the calibration block 27 is slid on the moving guide rail 26 so that the calibration block 27 passes through six mechanism probes in sequence.

[0032] Further, the calibration block 27 includes a slider 273 disposed on the moving guide rail 26. A cushion block 272 is connected to the top side of the slider 273, and a zeroing block 271 is installed on the top of the cushion block 272. The zeroing block 271 extends from one side of the moving guide rail 26 to the bottom side area of the laser probe 25. The slider 273 is in close contact with the moving guide rail 26 and can slide stably.

[0033] Operation process: Before detecting the online foil, the calibration block 27 needs to be installed on the moving guide rail 26. At this time, push the calibration block 27 to move, so that the calibration block 27 passes through the top sides of the 6 laser probes 25 in sequence. The adjustment platform 24 can level the connected laser probe 25 according to the actual situation. After the laser probe 25 is leveled, when detecting the foil, the foil is in a state of continuous movement, and the probe is also in a state of reciprocating movement. The moving direction of the probe is along the width direction of the foil (that is, when the foil is output, if the moving direction of the foil is the X direction at this time, the moving direction of the probe is the Y direction). The driving mechanism 22 drives the laser probe 25 to move left and right. The 6 laser probes 25 irradiate from bottom to top, and the emitted rays are perpendicular to the foil. The light emitted by the reflection sensor is perpendicular to the foil. Through the adjustment of the emitter lens, the reflected light is made oblique and finally collected and detected by the photosensitive element. The operation detection of the device and the reception of data are all completed by the console 1.

[0034] Embodiment 2 Refer to Figures 1-8 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: an adaptive unit 3 is provided on the calibration block 27. The adaptive unit 3 is used to ensure that when the calibration block 27 adjusts the balance of the six groups of laser probes 25, the calibration block 27 can move stably while maintaining a horizontal state.

[0035] Specifically, the adaptive unit 3 includes a stabilizing block 31 installed on the outer wall of the cushion block 272. A threaded rod 311 is installed through the stabilizing block 31 from top to bottom. The bottom end of the threaded rod 311 is connected to a support frame 312. The support frame 312 and the stabilizing block 31 are guided by a guide rail. A roller 313 is installed at the bottom of the support frame 312, and the roller 313 can contact the top of the moving guide rail 26.

[0036] Further, the zeroing block 271 is movably connected to a sliding plate 32. A support column 321 is installed at the bottom of the sliding plate 32. A ball sleeve 322 is installed at the bottom end of the support column 321. A universal ball 323 is lubricatingly installed inside the ball sleeve 322. A calibration touch plate 324 is installed at the bottom of the universal ball 323.

[0037] Further, the cooperation of the calibration touch plate 324, the universal ball 323 and the ball sleeve 322 enables the calibration touch plate 324 to maintain the bottom end face in a horizontal state by relying on its own gravity.

[0038] Further, a locking shaft 33 is installed on the top of the skateboard 32, and the bottom end of the locking shaft 33 extends into the interior of the support column 321, and this extended end is close to the top side of the universal ball 323. A fixed shaft 331 is installed on the inner wall of the locking shaft 33, the fixed shaft 331 is connected to a fork-shaped locking member 332, a locking groove 333 is formed on the inner wall of the support column 321, and the locking groove 333 and the locking end of the fork-shaped locking member 332 are on the same side. A fixing spring 334 is installed on the outer wall of the locking shaft 33, and one end of the fixing spring 334 is connected to the bottom side of the fork-shaped locking member 332.

[0039] Further, a suction cup 341 is installed at the bottom end of the locking shaft 33. A retaining piece 342 is placed on the inner bottom wall of the locking shaft 33. An extension shaft 343 is installed on the top of the retaining piece 342. A seesaw 344 is installed on the bottom side of the fork-shaped locking member 332, and one end of the seesaw 344 extends into the interior of the extension shaft 343. A spring presses against the retaining piece 342, so that the retaining piece 342 blocks the air outlet channel of the suction cup 341. When discharging air, the retaining piece 342 can be triggered to open, and this channel cannot intake air by itself, so that the negative pressure of the suction cup 341 can be maintained.

[0040] Further, an unlocking rod 35 is installed on the top of the locking shaft 33, and the bottom end of the unlocking rod 35 extends to the top side of the fork-shaped locking member 332. When unlocking, the unlocking rod 35 can trigger the fork-shaped locking member 332 to move.

[0041] All other structures are the same as those in Embodiment 1.

[0042] Operation process: After the slider 273 is connected to the movable guide rail 26, the threaded rod 311 can be rotated, and the rotation of the threaded rod 311 drives the support frame 312 to move, so that the roller 313 of the support frame 312 is pressed against the movable guide rail 26, so that the slider 273 with a shaking gap is lifted up, so that even if there is a gap between the slider 273 and the movable guide rail 26, it does not affect the adjustment of the laser probe 25, and after the roller 313 is in close contact with the movable guide rail 26, its The zeroing block 271 may tilt. When the zeroing block 271 tilts, its calibration touch plate 324 can always remain in a horizontal state by relying on the connection between the sleeve ball 322 and the universal ball 323. At this time, it is only necessary to press the locking shaft 33. When the locking shaft 33 moves downward, its suction cup 341 is in contact with the top of the universal ball 323, and as it is squeezed, the gas of the suction cup 341 is squeezed out from the baffle 342, so that the universal ball 323 is touched by the suction cup 341 and the negative pressure state is carried out. When the fork-shaped locking piece 332 on the locking shaft 33 moves to the locking groove 333, the fixing spring 334 embeds the bottom end of the fork-shaped locking piece 332 into the locking groove 333, so that the locking shaft 33 will not move back. At this time, the horizontal state of the calibration contact block is maintained. At this time, the calibration block 27 can be moved to slide, which effectively improves the detection of the parallelism of the laser probe 25. When unlocking is required, only the unlocking lever 35 needs to be pressed, and the unlocking lever 35 contacts the fork-shaped locking piece 332. The top of 32 is tilted, so that the bottom end of the fork-shaped locking member 332 is slightly retracted, so that the fork-shaped locking member 332 can be disengaged from the locking groove 333, and when the bottom end of the fork-shaped locking member 332 is displaced, the rocker 344 on the bottom side of the fork-shaped locking member 332 simultaneously drives the extension shaft 343 to lift up, and the extension shaft 343 lifts the baffle 342, so that the suction cup 341 can restore normal air pressure, and the locking shaft 33 is also restored by the spring, and the calibration contact block can restore to a free state.

[0043] Working principle: Before conducting online foil inspection, the calibration block 27 needs to be installed on the moving guide rail 26. At this time, after the slider 273 is connected to the moving guide rail 26, the threaded rod 311 can be rotated. The rotation of the threaded rod 311 drives the support frame 312 to move, so that the roller 313 of the support frame 312 is pressed against the moving guide rail 26, so that the slider 273 with a shaking gap is lifted up, so that even if there is a gap between the slider 273 and the moving guide rail 26, it does not affect the adjustment of the laser probe 25, and after the roller 313 is in close contact with the moving guide rail 26, its zeroing block 271 may tilt. When the zeroing block 271 tilts, its calibration touch plate 324 The connection between the sleeve ball 322 and the universal ball 323 can always maintain a horizontal state. At this time, you only need to press the locking shaft 33. When the locking shaft 33 moves downward, its suction cup 341 is in contact with the top of the universal ball 323, and as it is squeezed, the gas in the suction cup 341 is squeezed out from the baffle 342, so that the universal ball 323 is pressed by the suction cup 341 and the negative pressure state is stabilized. When the fork-shaped locking piece 332 on the locking shaft 33 moves to the locking groove 333, the fixing spring 334 embeds the bottom end of the fork-shaped locking piece 332 into the locking groove 333, so that the locking shaft 33 will not move back. At this time, the horizontal state of the calibration contact block is maintained, and the calibration block 27 can be moved to The calibration block 27 passes through the top sides of the six laser probes 25 in sequence, and the adjustment platform 24 can level the connected laser probes 25 according to actual conditions. After the laser probes 25 are leveled, the calibration block 27 can be disassembled by pressing the unlocking lever 35. The unlocking lever 35 touches the top raised part of the fork-shaped locking piece 332, so that the bottom end of the fork-shaped locking piece 332 retracts slightly, so that the fork-shaped locking piece 332 can be disengaged from the locking groove 333, and when the bottom end of the fork-shaped locking piece 332 is displaced, the rocker 344 on the bottom side of the fork-shaped locking piece 332 synchronously drives the extension shaft 343 to lift up, and the extension shaft 343 lifts the blocking piece 342, so that the suction cup 341 can return to the normal state. Normal air pressure, and the locking shaft 33 is also restored by the spring, at this time the calibration contact block can be restored to a free state, when the foil is detected, the foil is in a state of continuous movement, and the probe is also in a state of continuous reciprocating movement, the moving direction of the probe is along the width direction of the foil (that is, when the foil is output, if the moving direction of the foil is the X direction, then the moving direction of the probe is the Y direction), the driving mechanism 22 drives the laser probe 25 to move left and right, the 6 laser probes 25 illuminate from bottom to top, the emitted rays are perpendicular to the foil, the light emitted by the reflection sensor is perpendicular to the foil, and the reflected light is adjusted by the transmitter lens so that the reflected light is oblique, and is finally collected and detected by the photosensitive element.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
