[0002] After the brake pads are produced, in order to ensure the quality and safety of the products, the surface flatness inspection is generally required. This step helps to detect the defects that may occur during the production process, such as uneven wear, surface damage or other manufacturing defects. By inspecting the two working surfaces of the brake pads, it can be ensured that they all meet specific quality standards, so as to provide reliable braking performance after being installed on the vehicle. Since the brake pads have two sides, they need to be flipped during the inspection. The number of brake pads produced in the factory is huge. If manual flipping and inspection are relied on, the repeated manual flipping and inspection are repetitive labors, which may cause fatigue of workers and affect the inspection quality and work efficiency; manual inspection depends on the experience and judgment of the inspectors, and different workers may have different inspection standards and meticulousness, resulting in differences in inspection results; therefore, manual inspection is difficult to meet the high-efficiency production requirements, and a new mechanical structure needs to be developed to replace manual operation.

[0031] The pushing device 2 includes a push plate 21 and a translation driver 41. The length of the push plate is determined according to requirements. The push plate 21 is connected to the movable end of the translation driver 41. The push plate 21 is pushed by the translation driver 41 to contact the workpiece, so as to push the workpiece away from the conveyor belt. In this embodiment, both the telescopic driver 74 and the translation driver 41 adopt existing air cylinders or hydraulic cylinders, preferably air cylinders, and the flipping driver 42 is selected as a motor.

[0032] The magnetic attraction assembly 7 includes a flipping base 71, a lever 72, an electromagnet 73 and a telescopic driver 74. The magnetic attraction assembly 7 is connected to the flipping driver 42 through the flipping base 71, so that the flipping driver 42 drives the whole magnetic attraction assembly 7 to rotate. The telescopic driver 74 is installed on the flipping base 71, the electromagnet 73 is installed on the lever 72, and the lever 72 is connected to the movable end of the telescopic driver 74. The flipping base 71 is provided with a vacant position 75 for the lever 72 to be hinged. The movable end of the telescopic driver 74 extends into the vacant position 75 to connect the lever 72.

[0038] Action flow: In this embodiment, the workpiece is a brake pad. The brake pad is placed on the first conveyor belt 81 with the back facing upward. A photoelectric sensor is set at the workpiece table 5 to detect whether the brake pad is in place. When the brake pad of the first conveyor belt 81 moves to the position of the workpiece table 5, it is pushed into the magnetic suction groove 51 of the workpiece table 5 by the first pushing device 83. The magnetic suction component 7 of the first magnetic suction flipping device 85 is located above the magnetic suction groove 51 in the initial state. When the brake pad enters the magnetic suction groove 51, the telescopic driver 74 pushes the lever 72 into the magnetic suction groove 51, so that the electromagnet 73 sucks the brake pad tightly, and the flip driver 42 drives the flip seat 71 to rotate and turn the brake pad over; the translation driver 41 drives the moving seat 43 to slide along the slide rail 11 to put the brake pad into the detection position 61, and the flatness of the front of the brake pad is detected by the sensor 62 above the detection position 61. The sensor can be a photoelectric sensor, an ultrasonic sensor, a laser displacement sensor, etc. After the detection is completed, the moving seat 43 of the second magnetic flip device 86 is pushed to the detection device 6 by the translation driver 41, and the telescopic driver 74 of the second magnetic flip device 86 moves to lower the lever 72 connected thereto, so as to tighten the front of the brake pad in the detection position 61 through the electromagnet 73 of the lever 72, and the translation driver 41 pushes the moving seat 43 away from the detection device 6 to avoid collision with the detection device 6, and pushes the moving seat 43 to the second conveyor belt 82, and rotates the magnetic component 7 through the flip driver 42 to make the back of the brake pad face up, and cooperates with the electromagnet 73 of the second magnetic flip device 86 to disconnect and put the brake pad on the second conveyor belt 82. According to the data feedback from the sensor of the detection device, if the flatness test passes, the brake pad is transported to the next process through the second conveyor belt 82, and if the flatness test fails, the brake pad is pushed to the downward track 12 to the unqualified area through the second pushing device 84. The flipping angle range of the flipping actuator 42 is 180 degrees, so that the brake pad can be adjusted to face the front side upward or the back side upward through the magnetic attraction component 7 connected to the flipping actuator 42.
