[0032] 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.

[0033] like Figure 1-5As shown, the automatic production line thickness measuring equipment in this embodiment includes a stand 1, on which a rotating measuring platform 2 and a driving device for driving the rotating measuring platform 2 to rotate are arranged, and a first material sensor 6 is arranged on the side of the rotating measuring platform 2. In this embodiment, the driving device includes a rotating motor 3, and the lower end of the rotating measuring platform 2 is connected to a rotating spindle 4, and the rotating motor 3 is connected to the rotating spindle 4 through a transmission belt 5. The rotating motor 3 drives the rotating spindle 4 to rotate through the transmission belt 5, thereby driving the rotating measuring platform 2 to rotate. The first material sensor 6 can sense whether there is a workpiece 31 on the rotating measuring platform 2. In this embodiment, the first material sensor 6 adopts a magnetic switch, and other sensing devices with similar functions can also be adopted according to actual conditions.

[0034] A floating measuring device 7 is provided on the side of the rotating measuring platform 2, and the floating measuring device 7 is provided on a transfer device 8, and the transfer device 8 can transport the floating measuring device 7 in a horizontal plane toward or away from the rotating measuring platform 2. In this embodiment, the transfer device 8 is a pneumatic slide, and other structures with similar functions can also be used according to the situation in practice.

[0035] See also Figure 4-5 The floating measuring device 7 includes a bracket 9, an upper limit block 10 is provided at the upper end of the bracket 9, a rod hole 11 is provided on the upper limit block 10, and a vertical adjustment rod 12 is inserted into the rod hole 11. A limit member 13 is provided at the top of the adjustment rod 12, and a floating spring 14 is sleeved on the adjustment rod 12 between the limit member 13 and the upper limit block 10. A sliding probe frame 15 is provided at the lower end of the adjustment rod 12, and the sliding probe frame 15 can be slidably arranged on the bracket 9. In this embodiment, a vertical guide rail 16 is provided on the bracket 9, and a slider 17 is provided on the guide rail 16, and the sliding probe frame 15 is arranged on the slider 17. Then the sliding probe frame 15 can slide up and down along the guide rail 16.

[0036] The sliding probe frame 15 is provided with a rotatable swing probe frame 18, which is located at the side end of the sliding probe frame 15, and the rotation axis of the swing probe frame 18 is in the horizontal direction. In this embodiment, the sliding probe frame 15 is provided with a mandrel 19, and the swing probe frame 18 is arranged on the mandrel 19 through a bearing 20. Then the swing probe frame 18 can swing and rotate relative to the sliding probe frame 15 through the bearing 20. A dust cover 21 is provided on the swing probe frame 18 at a position opposite to the bearing 20 to protect the bearing 20 and facilitate maintenance and repair in the later stage. In this embodiment, the left and right ends of the sliding probe frame 15 are respectively provided with side baffles 22, and the two side baffles 22 are respectively located on both sides of the swing probe frame 18. A limit spring 23 is provided between the side baffle 22 and the swing probe frame 18, and a total of four limit springs 23 are provided here, which are respectively located at the upper and lower sides of the swing probe frame 18. When the swing probe frame 18 swings, the limit spring 23 can provide a certain buffering effect thereon and can also promote the resetting of the swing probe frame 18 .

[0037] The lower end of the swing probe frame 18 is provided with a fixed probe 24, and the upper end of the swing probe frame 18 is provided with a movable probe 25. In this embodiment, two fixed probes 24 are provided to ensure that they are in close contact with the workpiece 31 during the rotation process, and to ensure that the measurement result is not affected by the rotation. In this embodiment, the top of the fixed probe 24 is set to be slightly higher than the surface of the rotating measurement platform 2 by 0.5 mm, so that when the fixed probe 24 moves toward the workpiece 31, the fixed probe 24 is gradually pressed down by the workpiece 31.

[0038] An automatic unloading device and an unloading conveying device 26 are arranged on the side of the rotating measuring platform 2. The automatic unloading device is used to transfer the workpiece 31 on the rotating measuring platform 2 to the unloading conveying device 26. In this embodiment, the automatic unloading device includes a second material sensor 27 and an unloading cylinder 28. The second material sensor 27 is arranged at the feeding end of the unloading conveying device 26, and is used to determine whether there is a workpiece 31 here. In this embodiment, the second material sensor 27 adopts a photoelectric switch, and other similar sensor devices can also be used as needed in practice. The unloading cylinder 28 is connected to an unloading rod 29, and the ends of the unloading rod 29 and the unloading conveying device 26 are respectively located on both sides of the rotating measuring platform 2, and the ends of the unloading rod 29 are at the same height as the workpiece 31 on the rotating measuring platform 2. The cylinder drives the unloading rod 29 to move back and forth, so as to push the workpiece 31 on the rotating measuring platform 2 to the unloading conveying device 26. The unloading conveying device 26 here adopts a roller conveying device, and the unloading cylinder 28 is arranged on the roller conveying device and is located below the conveying roller.

[0039] The driving device, the transfer device 8, the movable probe 25, the automatic unloading device and the unloading conveying device 26 are respectively connected to the controller 30, and the controller 30 controls the overall operation of the equipment.

[0040] When the present embodiment is working, the first material sensor 6 determines whether there is a workpiece 31 on the rotating measuring platform 2. If there is no workpiece 31, the supporting loading equipment, such as a manipulator, places the measured workpiece 31 on the rotating measuring platform 2 and sends a start detection signal to the controller 30. The controller 30 starts the pneumatic slide to drive the floating measuring device 7 to approach the measured workpiece 31. The fixed probe 24 first contacts the lower surface of the workpiece 31. Since it is slightly higher than the lower surface of the workpiece 31 by 0.5 mm, the fixed probe 24 will be pressed down by the lower surface of the product during the approach process. Under the action of the floating spring 14, the entire floating measuring device 7 is floating, so after approaching, the floating measuring device 7 gradually moves down, so that the fixed probe 24 is adapted to the lower surface of the workpiece 31. Then the movable probe 25 starts to contact the upper surface of the workpiece 31 to achieve the measurement purpose.

[0041] After the pneumatic slide is in place, it sends a signal to the controller 30 indicating that it is in place, and then the rotating motor 3 starts to rotate, driving the rotating spindle 4 and the rotating measuring platform 2 to rotate, thereby driving the workpiece 31 to rotate, thereby realizing the detection of the thickness of the entire workpiece 31. During the rotation detection process, if an out-of-tolerance point occurs, the detection is stopped, the controller 30 outputs an alarm signal, and then the unqualified workpiece 31 is removed under manual intervention. After the rotation detection process, if the workpiece 31 is qualified, the controller 30 checks the signal of the second material sensor 27 to determine whether the unloading and conveying device 26 is full of material. If it is full of material, it waits. If it is not full of material, it sends a signal to the unloading cylinder 28, pulls the unloading rod 29, and pulls the workpiece 31 to be measured onto the unloading and conveying device 26.

[0042] The adjustment screw and the floating spring 14 are used together to adjust the position of the sliding probe frame 15, ensuring that the fixed probe 24 is slightly higher than the surface of the rotating measuring platform 2 by 0.5mm when not measuring, and can contact the lower surface of the workpiece 31 when measuring. The floating spring 14 generates elastic force to ensure that there is a certain pressure between the fixed probe 24 and the workpiece 31 to ensure that they will not separate during the rotation process. The bearing 20 and the mandrel 19 allow the swinging probe frame 18 to rotate freely within a small angle, so that the fixed probe 24 can fluctuate with the bottom surface of the workpiece 31, ensuring a good measurement effect.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
