Note that the following embodiments are merely illustrative in nature, and the present invention is not intended to limit its applicable objects or uses, and the present invention is not limited to the following embodiments.

[0024] Example

[0025] A detection device for preventing standard parts from being missed during brake assembly, wherein a plurality of standard parts are fixedly provided on the bottom surface of the brake 1, and the standard parts include screws and elastic pins. In the present embodiment, a screw 6 and an elastic pin 10 are fixedly provided on the bottom surface of the brake 1, and the detection device includes a detection frame and a plurality of standard parts detection components. Correspondingly, the present invention includes two standard parts detection components, and a brake positioning groove and a detection component groove are provided on the detection frame. The detection component groove is provided in the middle of the detection frame, and the shape of the brake positioning groove is adapted to the shape of the brake 1. The groove bottom height of the brake positioning groove is the same as the groove top height of the groove of the detection component groove. The standard parts detection component is provided in the detection component groove, and a plurality of detector supports 8 are provided at the bottom of the detection frame, and a rubber anti-slip sheet is provided at the bottom of the detector support 8.

[0026] The standard parts detection component includes a photoelectric sensor, a pressing sub-component and a controller. The photoelectric sensor includes a photoelectric transmitter 3 and a photoelectric receiver 2. The photoelectric transmitter 3 and the photoelectric receiver 2 are respectively connected to the controller. The photoelectric transmitter 3 is arranged on the lower side of the detection component groove, and the photoelectric receiver 2 is arranged on the upper side of the detection component groove. The photoelectric transmitter 3 and the photoelectric receiver 2 are arranged relatively to each other. The pressing sub-component includes an auxiliary pressure plate 4, an elastic member 9 and two positioning columns 7. The pressing sub-component is arranged between the photoelectric transmitter 3 and the photoelectric receiver 2. Two positioning holes are provided on the auxiliary pressure plate 4. One end of the positioning column 7 is fixed to the bottom surface of the detection component groove, and the other end passes through the positioning hole. In the present invention, the elastic member 9 is a compression spring. One end of the elastic member 9 is fixed to the bottom surface of the detection component groove, and the other end contacts the bottom surface of the auxiliary pressure plate 4. The position of the auxiliary pressure plate 4 is adapted to the position of the standard part of the bottom surface of the brake 1. The height of the bottom surface of the auxiliary pressure plate 4 is higher than the photoelectric sensor.

[0027] A limit plate groove is opened on the top of the auxiliary pressure plate 4, and a limit plate 5 is fixed on the edge of the detection component groove. One end of the limit plate 5 is fixed to the top of the upper side of the detection component groove, and the other end abuts against the limit plate groove of the auxiliary pressure plate 4. A standard part abutment groove is opened at the top center of the auxiliary pressure plate 4, and the standard part abutment groove is circular.

[0028] When the detection device for preventing standard parts from being missed during brake assembly of the present invention is used, the detection device is placed horizontally, and then the brake 1 is placed horizontally in the brake positioning groove on the detection frame. If the standard parts of the brake 1 are not missed, the screws 6 and the positioning pins 10 at the bottom of the brake 1 respectively press down the corresponding auxiliary pressure plates 4, and the two auxiliary pressure plates 4 move downward to block the light beams emitted by the photoelectric transmitter 3. Both photoelectric receivers 2 cannot receive the light beams, and the controller determines that the standard parts of the brake 1 are not missed. If the standard parts of the brake 1 are missed, at least one auxiliary pressure plate 4 cannot move downward to block the light beam emitted by the photoelectric transmitter 3. Correspondingly, when one or two photoelectric receivers 2 cannot receive the light beam, the controller determines that the standard parts of the brake 1 are missed.

These embodiments can also be implemented in various other ways, and various omissions, substitutions, and changes can be made without departing from the technical concept of the present invention.
