Of course, the clamping device can also move the movable baffle 3 until the distance is equal to the chord length of the magnetic shoe 34, and then the magnetic shoe 34 is put on the positioning assembly 4, so that the magnetic shoe 34 can be placed more quickly, and the distance between the movable baffle 3 and the fixed baffle 2 can be adjusted along with the chord length of the magnetic shoe 34, so that the clamping of the magnetic shoes 34 with different sizes can be realized, and the application range of the whole system is larger. In the first transmission device of the magnetic shoe surface defect inspection system, the electromagnet 6 can contact the magnetic shoe 34 under the action of the first telescopic part 7, so that the magnetic shoe 34 can be sucked, then the first telescopic part 6 can be transmitted to the upper part of the convex surface detection device under the action of the first transmission assembly, and at the moment, the first telescopic part 6 continuously extends out to enable the magnetic shoe 34 to abut against the first detection curved surface formed by the first probe 9. When the convex surface of the magnetic shoe 34 has no defect, the convex surface of the magnetic shoe 34 is attached to the first detection curved surface, all the first probes 9 are simultaneously pressed to trigger the first touch switch, and when the convex surface of the magnetic shoe 34 has a defect, the pressing time of the defect position of the convex surface of the magnetic shoe 34 to the corresponding first probes 9 is different. When the convex area exists, a part of the first probes 9 can be touched in advance, and then a part of the first touch switches are triggered in advance, on the contrary, a part of the first probes 9 can be touched after being delayed, and then the corresponding first touch switches are triggered after being delayed, so that whether the convex surface of the magnetic shoe 34 has defects or not can be judged according to the action states of the first touch switches. And then, the second transmission device further transmits the magnetic shoe 34 with the checked convex surface to a concave surface detection device for checking, wherein the detection method of the concave surface detection device is similar to that of the convex surface detection device, and the detection curved surface formed by the second probe 13 is used for checking the concave surface of the magnetic shoe 34, so that whether the concave surface of the magnetic shoe 34 has defects or not can be judged. So, this magnetic shoe surface defect inspection system has just realized the defect inspection to the concave-convex face of magnetic shoe 34, and detect through the mode of probe, can avoid through the great error that visual inspection caused, improve the inspection effect of defect, this system carries out the defect inspection to magnetic shoe 34 through full automatic mode simultaneously, avoid the manual work to detect respectively with the naked eye, can reduce intensity of labour, protect workman's eyes simultaneously, and can improve the efficiency and the false retrieval rate of defect inspection, guarantee the precision of magnetic shoe 34 surface defect inspection.

The controller of the magnetic shoe surface defect inspection system can judge whether the distance between the movable baffle plate 3 and the fixed baffle plate 2 reaches the chord length of the magnetic shoe 34 or not according to the distance detected by the distance measuring sensor I5, so that the position of the magnetic shoe 34 is unique after the magnetic shoe is placed, the first electromagnet 6 can be prevented from being askew sucked, and the first subsequent electromagnet 6 can be conveniently and accurately sucked. The controller can also be according to the distance that second distance measuring sensor 14 and third distance measuring sensor 15 detected, fix a position the position that magnetic shoe 34 was located in the inspection process to after fixing a position at every turn, through expansion part 7 and expansion part two 11, magnetic shoe 34 moves to and detects curved surface one and detect curved surface two and go up and detect, thereby accomplish the full-automatic defect inspection to magnetic shoe 34, realized full automatization and intellectuality.

The emitter and the receiver of the first infrared sensor 30 are respectively installed on the fixed baffle 2 and the movable baffle 3, and the light emitted from the emitter passes through the space below the magnetic shoe 34 on the positioning assembly 4 to be transmitted to the receiver. When the magnetic shoe 34 is tilted, the convex end of the magnetic shoe 34 blocks light so that the infrared sensor 30 generates a first switching signal. When the first infrared sensor 30 sends out a first switch signal, the controller drives the inclination alarm to send out an inclination alarm signal. Therefore, when the magnetic shoe 34 is subjected to defect inspection and is inclined, the inclination alarm can send out an alarm signal, and the magnetic shoe 34 can be adjusted in time at the moment, so that the inspection is ensured to be carried out smoothly.

When the weight detected by the first weighing sensor 31 or the second weighing sensor 32 is larger than the preset weight, the controller judges that the magnetic shoe 34 has overweight defects or the first probe 9/the second probe 13 has separation conditions. When the weight detected by the first weighing sensor 31 or the second weighing sensor 32 is smaller than the preset weight, the controller judges that the magnetic shoe 34 has the shortage defect.

Of course, in other embodiments, in order to avoid the falling probe directly attracted to the electromagnet and affecting the weighing accuracy, the probe may be made of a material that cannot be magnetically attracted.
