[0027] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0028] like Figures 1-9 As shown, an automotive brake pad production line includes a base plate 1, brake pads 3, and warning iron plates 31. The brake pads 3 have protrusions for mounting the warning iron plates 31. The base plate 1 is provided with a second bracket 13. Below the second bracket 13 are a grinding mechanism 5, a rotating mechanism 6, and a driving mechanism 7. The driving mechanism 7 is used to provide power output to the grinding mechanism 5, and the rotating mechanism 6 is used to make the grinding mechanism 5 rotate around the protrusions for one revolution for grinding.

[0029] A conveyor belt 2 is provided on the base plate 1, a first support 12 is provided on the base plate 1, and an electromagnet 4 is provided on the first support 12. The electromagnet 4 is located between the upper and lower belt surfaces of the conveyor belt 2 and is close to the upper belt surface. The electromagnet 4 is used to attract the brake pad 3.

[0030] The electromagnet 4 is switched between state A and state B. When the electromagnet 4 is in state A, the electromagnet 4 is not powered and the conveyor belt 2 moves toward the grinding mechanism 5. When the electromagnet 4 is in state B, the electromagnet 4 is powered, the conveyor belt 2 stops moving and the electromagnet 4 attracts the brake pad 3, and the grinding mechanism 5 starts grinding the brake pad 3.

[0031] The rotating mechanism 6 includes a mounting plate 61, a return frame 63, and a rotating motor 64. A rotating shaft 62 is provided on the mounting plate 61, and the rotating motor 64 is mounted on the second bracket 13, and its output end is connected to the rotating shaft 62.

[0032] The grinding mechanism 5 includes a housing 51, rollers 52, a sanding belt 53, and a light curtain sensor 56. The rollers 52 are cylindrical and coaxially mounted on the housing 51. Two sets of rollers 52 are arranged along the length of the housing 51. The sanding belt 53 is sleeved on the two sets of rollers 52 and rotates as the rollers 52 roll. A guide rod 54 is provided on the upper end face of the housing 51, penetrating the thickness direction of the mounting plate 61. The guide rod 54 and the mounting plate 61 form a sliding guide fit. A frustum is provided on the end face, and a spring 57 is provided between the frustum and the mounting plate 61. The elastic force of the spring 57 is used to drive the frustum to move away from the mounting plate 61. An iron block 511 is provided on the outer shell 51. The iron block 511 is located between the sanding belts 53 and is in contact with the lower sanding belt surface. The outer surface of the iron block 511 is made of smooth material. A third bracket 55 is provided on the outer shell 51. A light curtain sensor 56 is installed on the third bracket 55. The light curtain sensor 56 is used to detect whether the grinding mechanism is on the protrusion.

[0033] A fourth bracket 65 is provided on the side of the mounting plate 61 facing the grinding mechanism 5. The drive mechanism 7 includes a first bevel gear 72, a second bevel gear 73, a third bevel gear 74, and a fourth bevel gear 75. The second bevel gear 73 is mounted on the fourth bracket 65, and a motor 71 is provided on the fourth bracket 65. The rotation direction of the motor 71 changes intermittently. The first bevel gear 72 and the second bevel gear 73 form a gear power mesh, the second bevel gear 73 and the third bevel gear 74 form a gear power mesh, and the third bevel gear 74 and the fourth bevel gear 75 form a gear power mesh. 2. A power connection is established between the output end of the motor 71 and the output end of the fourth bevel gear 75 and the belt roller 52. The motor 71 is used to transmit power to the belt roller 52. A bevel gear bracket 512 is provided on the side of the housing 51 facing the grinding mechanism 5. The third bevel gear 74 is mounted on the bevel gear bracket 512. One end of the second bevel gear 73 is a spline groove, and one end of the third bevel gear 74 is a spline. When the electromagnet 4 is in state A, the spline is located above the spline groove, and the power to the belt roller 52 is disconnected. When the electromagnet 4 is in state B, the spline is located in the spline groove and the power to the belt roller 52 is connected.

[0034] Two sets of grinding mechanisms 5 are arranged along the width direction of the outer shell 51. The driving mechanism 7 mirrors the two sets along the middle surface of the facing surfaces of the two sets of outer shell 51. The two sets of driving mechanisms 7 are connected by power. The return frame 63 is located in the area formed by the facing surfaces of the two sets of outer shell 51. The return frame 63 and the mounting plate 61 form a sliding guide fit. The return frame 63 is made of ferromagnetic material.

[0035] A dust collection mechanism 8 is provided on the side of the outer casing 51 away from the sanding belt 53. The dust collection mechanism 8 includes an air intake 81, a casing 82, a fan blade 83, a pipe 84, and a collection box 85. The fan blade 83 is coaxially mounted on the casing 82. Both ends of the casing 82 are connected to the air intake 81 and the collection box 85 through the pipe 84. A helical gear mechanism 9 is installed at one end of the fan blade 83. The helical gear mechanism 9 includes a gear 91, a helical gear 92, and a casing 93. The gear 91 is coaxially connected to the fan blade 83. The casing 93 is mounted on the mounting plate 61. A spring a is provided between the helical gear 92 and the casing 93 to keep them away from each other. The spring a has a very small elastic coefficient. A unidirectional power connection is formed, and during the process of electromagnet 4 changing from state B to state A, the plane on the helical tooth 92 that is away from the helical tooth surface contacts the tooth surface on gear 91. The force formed by the plane and the tooth surface on gear 91, and the component of the force pointing to spring a, will not drive the helical tooth 92 to move away from gear 91. Thus, the movement of the helical tooth 92 drives gear 91 to rotate, and in turn drives fan blade 83 to rotate, thereby forming an upward wind. During the process of electromagnet 4 changing from state A to state B, the force formed by the contact between the helical tooth surface of the helical tooth 92 and the tooth of gear 91, and the component of the force pointing to spring a, overcomes the elastic force of spring a and drives the helical tooth 92 to move away from gear 91.

[0036] When starting work, the motor 71 is started, and the conveyor belt 2 is started to transport the brake pad 3 to the electromagnet 4. At this time, the electromagnet 4 is in state A, and the power transmission component of the roller 52 is interrupted. The motor 71 drives the second bevel gear 73 to idle. Then the electromagnet 4 is powered, so that the electromagnet 4 switches from state A to state B. At this time, the helical gear 92 will not drive the fan blade 83 to rotate, avoiding the formation of a downward airflow that blows foreign objects on the surface of the brake pad 3 into the area below the sanding belt 53. At the same time, the electromagnetic attraction moves the grinding mechanism 5, the third bevel gear 74 and the fourth bevel gear 75 toward the brake pad 3 on the one hand, and fixes the brake pad 3 on the other hand. As the third bevel gear 74 gradually moves down and meshes with the second bevel gear 73, the sanding belt 53 is driven to rotate, and the surface of the brake pad 3 is then ground.

[0037] The motor 71 intermittently adjusts its rotation direction, so that the burrs on the edge of the brake pad 3 are sometimes subjected to force in the direction of the burrs and sometimes to force in the opposite direction of the burrs, thus making the burrs more thoroughly removed. After a period of time, the electromagnet switches from state B to state A, and the grinding mechanism 5, the third bevel gear 74 and the fourth bevel gear 75 are reset. The fan blade 83 is driven to rotate through the helical gear 92, generating an upward airflow and forming an upward suction force to suck away the newly ground debris in time and store it in the collection box 85. The collection box 85 is a technology that can be implemented in the prior art and will not be described in detail. If the debris is not sucked away in time, the debris will be between the sanding belt 53 and the brake pad 3. When the sanding belt 53 rotates, the sanding belt 53 and the debris will form rolling friction, which will greatly reduce the grinding efficiency and seriously affect the service life of the sanding belt 53.

[0038] The conveyor belt 2 carries the brake pad 3 forward a certain distance, and the process is repeated. When the protrusion moves to the bottom of the return frame 63, the grinding mechanism 5 moves downward and is relatively displaced with the return frame 63, which cannot move downward. The light curtain sensor 56 detects the return frame 63 and then starts the rotating motor 64. The sanding belts 53 on both sides of the return frame 63 rotate around the protrusion while grinding, ensuring that the sanding belts 53 do not come into contact with the protrusion. Even when the protrusion moves to the bottom of the sanding belts 53, the power component is interrupted, so on the one hand, it ensures that the area around the protrusion is ground, and on the other hand, it protects the protrusion from being damaged by the grinding mechanism.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
