Description

Technical Field

[0001] The invention relates to the field of galvanometer motor sector pieces, and in particular to a device for detecting the flatness of galvanometer motor sector pieces. Background Art

[0002] The galvanometer motor is provided with a detection device for determining the angular position of a rotating element in the galvanometer motor, wherein the angular position of the rotating element can be determined by using a photocell, a light source and a shading plate (fan-shaped piece) arranged between the photocell and the light source.

[0003] For example, a Chinese patent with publication number CN218387163U discloses a galvanometer motor, including a wire control unit, a housing unit and a lens unit, wherein the wire control unit includes: a PCB board with multiple photocells, a shading plate and a light source, wherein the shading plate is arranged between the light source and the multiple photocells; the shading plate includes: a shielding portion and a fixing portion protruding outward along the center of one side surface of the shielding portion, wherein a positioning hole for fixing the shading plate is arranged in the fixing portion. The present application shortens the assembly spacing between the shading plate and the photocells through the special structural arrangement of the shading plate, thereby improving the detection accuracy of the photocells.

[0004] In summary, there are many drawbacks in the existing quality inspection of fan-shaped pieces, which are summarized as follows:

[0005] ① If the flatness of the shading plate (sector-shaped piece) does not meet the standard, the assembly distance between it and the photocell monomer cannot be guaranteed. During the operation of the galvanometer motor, some stray light cannot be completely blocked, resulting in low detection accuracy of the photocell and affecting the performance of the galvanometer motor;

[0006] ② Fan-shaped pieces are often screened manually, which is inefficient and may cause omissions or wrong selections, resulting in the misuse of unqualified products and the unqualified performance of the galvanometer motor. Summary of the invention

The feeding placement plate 12 is provided with a placement groove 121.

[0033] The group A suction equipment 31 includes a group A linear module 311, a group A lifting slide 312, and a group A suction device 313. The group A lifting slide 312 is connected to the group A linear module 311 for moving the group A suction equipment 31 up, down, left, and right.

The group B suction device 323 is connected to the group B lifting slide 322, and a group B suction part 3231 is provided at the lower end of the group B suction device 323.

[0034] The detection device 2 includes an in-place sensor 21, a detection sensor 22, and a bracket 23. The in-place sensor 21 and the detection sensor 22 are connected through the bracket 23. The in-place sensor 21 is a fiber optic sensor, and the detection sensor 22 is a distance sensor. A discharge bin 43 is provided on one side of the rotating platform 41. The discharge bin 43 is divided into a qualified bin and an unqualified bin. The detection slot 421 is divided into a detection area 4211 and an area to be detected 4212, which are used to correspond to the detection position of the upper detection sensor 22. The model selection of the distance sensor and the fiber optic sensor can be determined according to the actual accuracy requirements and cost. All sensors and movable devices are connected to the PLC, and the PLC sends and receives instructions.

[0035] Working mode: The fan-shaped piece is placed in the placement slot 121, and the in-position sensor 21 automatically detects the placement of the fan-shaped piece. If it is in place, it sends a signal, and the telescopic device 11 drives the loading placement plate 12 to move to one side. When it moves into place, the linear module 311 of group A drives the lifting slide 312 of group A to move toward the placement slot 121. The lifting slide 312 of group A moves downward to the placement slot 121. The suction device 313 of group A starts to work, and the suction part 3131 of group A sucks the fan-shaped piece through negative pressure. After suction, the lifting slide 312 of group A rises and moves to the detection slot through the linear module 311 of group A. 421, and after reaching it, the suction device 313 of group A releases the positive pressure, and the suction part 3131 of group A puts the sector piece into the detection slot 421 and then returns to the initial position at the beginning of the work.

After arriving, the B group lifting slide 322 will descend, and the B group suction device 323 will release the positive pressure. After the B group suction part 3231 puts the fan-shaped piece into the qualified bin, the B group lifting slide 322 will rise and return to the starting position.

[0038] If the fan-shaped piece is unqualified, it will move toward the unqualified bin through the B group linear module 321. After arriving, the B group lifting slide 322 will descend, the B group suction device 323 will release the positive pressure, and the B group suction part 3231 will place the fan-shaped piece into the unqualified bin.
