Technical Field

[0001] This invention relates to the field of material conveying technology, specifically to a material conveying mechanism for processing automobile hoof blocks with visual inspection. Background Technology

[0002] Motorcycle brake shoes are critical components in motorcycle and automobile braking systems, and their manufacturing quality directly affects driving safety. During the production process, it is necessary to inspect their appearance and dimensions, and then classify and collect qualified and unqualified products.

[0003] Chinese patent CN210236276U discloses a high-efficiency shoe block supply device for automotive compressors, including a frame, a housing fixedly connected to the top of the frame, a shoe block conveying box disposed within the inner cavity of the housing, the top of the shoe block conveying box extending to the outside of the housing, a rectangular flexible material channel fixedly connected to the right side of the shoe block conveying box, and a shoe block conveying plate fixedly connected to the end of the shoe block conveying box away from the shoe block conveying box. This invention, by setting a lifting plate, can raise the shoe blocks to a higher height, facilitating their discharge from the outlet material channel. Through the coordinated operation of the frame, housing, shoe block conveying box, rectangular flexible material channel, shoe block conveying plate, fixed plate, cylinder, lifting plate, outlet material channel, and material shortage alarm sensor, it has the advantages of simultaneously conveying shoe blocks through ten material channels, resulting in high conveying efficiency.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-6 This invention provides a technical solution: a material conveying mechanism for processing automotive hoof blocks with visual inspection, comprising an inspection component 2 and a material conveying component 3 disposed within a machine body 1. The material conveying component 3 is connected to a material distribution component 4. A material collection guide rail 11 is fixedly connected to the surface of the machine body 1, facilitating the collection and transportation of qualified hoof blocks to the next stage. A collection chamber 12 is provided at the bottom of the machine body 1 for collecting unqualified hoof blocks. A movable collection container is disposed within the collection chamber 12. The horizontal position of the material collection guide rail 11 is higher than that of the collection chamber 12. The machine body 1 is fixedly connected to a conveyor rail 31, thereby enabling the conveyor rail 31 to... The conveyor rail 31 is fixed inside the machine body 1. One end of the conveyor rail 31 is hinged to a baffle 32 via a torsion spring hinge. When the hoof block is moved out of the conveyor rail 31, the position of the hoof block can be easily corrected by the baffle 32. The output direction of the conveyor rail 31 is tangent to the arc surface of the base plate 33. A vision inspection instrument 24 and a connecting rod 25 are fixedly connected to the top of the machine body 1. The vision inspection instrument 24 can be used to inspect the hoof block entering the base plate 33 from above. The vision inspection instrument 24 is located directly above the baffle 32. A torsion spring pressure sensor is installed inside the baffle 32. When the baffle 32 rotates, the torsion amount of the torsion spring changes, the pressure increases, thereby triggering the vision inspection instrument 24.

[0019] The surface of the external gear ring 21 is rotatably connected to the body 1. A drive device is installed inside the body 1 to drive the external gear ring 21. The bottom surface of the internal gear ring 22 is fixedly connected to the body 1. The internal gear ring 22 has a discharge port 23, which is connected to the collection bin 12. When the hoof block fails the inspection, it can enter the discharge port 23 through the material distribution component 4. The gear 38 is positioned between the internal gear ring 22 and the external gear ring 21 and meshes with both of them. The external gear ring 21 and the internal gear ring 22 are coaxially designed. When the drive device drives the external gear ring 21 to rotate, the gear 38 rotates accordingly. At the same time, under the action of the internal gear ring 22, the gear 38 begins to rotate and revolve around the center of the internal gear ring 22. The gear 38 is fixedly connected to the base plate 33. At this time, the base plate 33 can also rotate accordingly. When the hoof block fails the inspection, it can enter the collection bin 12. When the block is fixed to the surface of the substrate 33, the hoof block can be displayed from multiple angles, thereby avoiding blind spots in the detection. One end of the connecting rod 25 is fixedly connected to the upper end of the machine body 1, and the other end is rotatably connected to the rotating drum 26 through a bearing. A drive rotation device is set inside the connecting rod 25 to drive the rotating drum 26 to rotate at a constant speed. A laser sensor 27 and a vision inspection instrument 28 are fixedly connected to the surface of the rotating drum 26. The laser sensor 27 and the vision inspection instrument 28 are on the same axis, and their output directions are facing the substrate 33. The laser sensor 27 can monitor the position of the substrate 33 in real time, thereby providing parameters for the drive rotation device, so as to ensure that the vision inspection instrument 28 is facing the substrate 33. The side of the hoof block can be detected by the vision inspection instrument 28.

[0020] A rotating groove 35 is formed on the surface of the substrate 33, and an internal cavity 34 is formed inside the substrate 33. An electric push rod 36 is fixedly connected to the top of the internal cavity 34. The output end of the electric push rod 36 is vertically downward and fixedly connected to the clamp 37. The electric push rod 36 can drive the clamp 37 to move vertically up and down. A guide rod 373 and a motor 371 are fixedly connected inside the clamp 37. A lead screw 372 is fixedly connected to the output end of the motor 371. The other end of the lead screw 372 is rotatably connected to the clamp 37 through a bearing. The guide rod 373 and the lead screw 372 both pass through a linkage rod 374. Sliding grooves are formed on both sides of the linkage rod 374. 375 is threadedly connected to lead screw 372. When lead screw 372 rotates, linkage rod 374 can move vertically under the restriction of guide rod 373. Each of the two arc blocks 376 is rolledly connected in the slide groove 375. The arc blocks 376 are rotatably connected to the clamp 37. The other ends of the two arc blocks 376 are respectively fixedly connected to clamping plate 377 and top block 378. One end of top block 378 is fixedly connected to rubber block 379. The rubber block 379 can improve the clamping force of clamp 37 on the shoe block. A guide groove 3710 is opened in the top block 378. A slider 3713 is slidably connected in the guide groove 3710. 713 has rotating rods 3714 hinged at both ends, and rollers 3716 rotatably connected to the other end of the rotating rods 3714. The rollers 3716 rotate horizontally. Rollers 3716 and springs 3715 are installed inside the top block 378, allowing for automatic adjustment along the inner arc surface of the shoe block to avoid jamming caused by rigid contact. Spring 3715 is fixedly connected to the middle of the rotating rods 3714, and the other end of the spring 3715 is fixedly connected to the slider 3713. Spring 3715 is in a stretched state. Initially, the angle between the rotating rods 3714 and the top block 378 is an acute angle. Motor 3711 is fixedly connected inside the top block 378. The output end of motor 3711 is fixedly connected to lead screw 3712. Lead screw 3712 passes through slider 3713 and is threadedly connected to it. When motor 3711 drives lead screw 3712 to rotate, slider 3713 begins to slide linearly, thereby applying pressure to rotating rod 3714. Rotating rod 3714 simultaneously applies pressure to roller 3716, causing it to roll along the inner arc surface of the shoe block. At this time, the angle between rotating rod 3714 and top block 378 increases. At the same time, the tension of spring 3715 on the two rotating rods 3714 allows rubber block 379 to be located at the midpoint of the inner arc surface of the shoe block, thereby fixing the position of the shoe block.

[0021] The feeding assembly 4 includes two side plates 41, with electromagnets 42 fixedly connected to the surface of each side plate 41. The side plate 41 has a multi-layer composite structure, consisting of, from bottom to top: a memory alloy driving layer 422, which can be made of nickel-titanium-copper memory alloy sheet with a phase transition temperature of 50°C and a downward bending 60° in the high-temperature state; and a memory alloy reset layer 421, which can be made of titanium-nickel-niobium memory alloy sheet. This material has a two-way memory effect, a phase transition temperature of 80°C, and an upward bending reset state in the high-temperature state. The two memory alloy layers form an interlocking structure at room temperature, allowing the side plate 41 to stably maintain a flat or downward bending state without being energized. An electromagnetic coil layer is provided between the two layers. This layer is a planar spiral copper coil used to heat the driving layer 422 and the reset layer 421. Both layers have good repeatability and long lifespan.

[0022] In actual use, the shoe block is input through the conveyor rail 31. At this time, the base plate 33 is located directly below the baffle 32. The electric push rod 36 pushes the clamp 37 to move upward. At this time, the lead screw 372 rotates, driving the linkage rod 374 to move upward, which in turn causes the arc block 376 to rotate. The rubber block 379 and the clamping plate 377 clamp the shoe block. During the process, the motor 3711 starts. The spring 3715 pulls on the rotating rod 3714, causing the roller 3716 to roll along the inner arc surface of the shoe block to calibrate the position of the shoe block. When the clamping is stable, the outer toothed ring 21 starts to rotate, which in turn drives the base plate 33 to rotate and revolve. During the process, the shoe block pushes open the baffle 32 and triggers the vision inspection instrument 24. Then, the electric push rod 36 drives the clamp 37 to descend, and the bottom surface of the shoe block is in contact with the base plate 33. At this time, the electromagnet 42 is activated to complete the positioning of the shoe block. The side plate 41 is in a low temperature and flat state and remains horizontal.

[0023] When the external gear ring 21 rotates, it drives the gear 38 to rotate the base plate 33 around the internal gear ring 22 while simultaneously rotating itself. During the rotation, the shoe changes angle and posture. During this process, the clamp 37 reverses its operation to release the grip on the shoe. The rotating drum 26 follows the base plate 33 through the laser sensor 27, thus ensuring that the vision inspection instrument 28 can perform real-time detection on the shoe. At the same time, the side plate 41 heats up, causing the driving layer 422 to heat up to 5-10° below the phase change point, thus maintaining a critical state. When the vision inspection instrument 28 detects that the shoe is qualified, when the base plate 33 rotates to the corresponding position of the collecting guide rail 11, the controller applies a large current to the side plate 41 closest to the collecting guide rail 11, and the electromagnet 42 on the other side is completely de-energized. At this time, the driving layer 422 rapidly heats up and exceeds the 50° phase change point, causing a phase change to occur. This causes the driving side plate 41 to bend downwards by 60°. At the same time, due to the high phase change temperature of the upper memory alloy and the two memory alloy layers... The alloy forms an interlock, at which point the side plate 41 remains stable and bends downward. When the side plate 41 bends to the correct position, the electromagnet 42 is de-energized, the magnetic field disappears, and the shoe block slides smoothly down the inclined plane into the collection guide rail 11 under the action of gravity. When the shoe block is detected as unqualified, the power supply and de-energization of the base plates 33 and electromagnet 42 on both sides are reversed. At this time, the shoe block slides down from the other side of the base plate 33 and enters the collection bin 12 through the discharge port 23, thus completing the sorting. After the sorting is completed, a reset current is passed through the electromagnetic coil layer of the side plate 41, causing the upper memory alloy to start heating up and exceed the 80°C phase change point. Through the reset phase change of the upper memory alloy bending upward, the lower memory alloy is forcibly pulled back to a flat state. After the power is cut off and the cooling is completed, both memory alloys return to flatness, the side plate 41 resets, and waits for the next cycle. The driving layer 422 and the reset layer 421 heat up and change phase rapidly after being energized, with a fast response speed and only energized at the moment of sorting, resulting in low energy consumption and high efficiency.

[0024] By integrating the detection component 2, the feeding component 3, and the distributing component 4 into one unit, and designing the clamp 37 and the distributing component 4 as independently detachable units, maintenance and repair are facilitated. The overall mechanism reduces the maintenance cost of long-term operation while ensuring multifunctionality. At the same time, it effectively detects the main areas outside the bottom surface of the hoof block during the rotation of the hoof block.
