Description

Technical Field

[0001] This invention relates to the field of bearing testing technology, specifically to an intelligent testing device for bearing processing with automatic calibration function. Background Technology

[0002] Bearings are an important component in mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. After bearing production, they also need to undergo certain tests, such as appearance quality inspection, vibration testing, hardness testing, and temperature testing.

[0003] Currently, when inspecting bearings in factories, most methods involve manually placing the bearings at the inspection position or using robotic arms and conveyor belts to transport the bearings to the inspection position. Manual inspection is inefficient, increases labor costs for workers, and is prone to human error. The second method, semi-automated inspection, requires stopping work during bearing inspection and waiting for the previous bearing to be inspected before transporting the next bearing, which also reduces inspection efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent testing device for bearing processing with automatic calibration function, so as to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An intelligent testing device for bearing processing with automatic calibration function is disclosed. The intelligent testing device includes a conveying mechanism, a rotating mechanism, a testing mechanism, a material guiding mechanism, and a distance measuring mechanism. The upper end of the conveying mechanism and the lower end of the rotating mechanism are fastened together. The rotating mechanism and the testing mechanism are fastened together. The testing mechanism is provided in several groups, which are arranged in an equidistant array along the axial direction of the rotating mechanism. The material guiding mechanism is provided in two groups, which are located at the feeding end of the conveying mechanism and are symmetrically placed on both sides of the conveying mechanism. The distance measuring mechanism is fastened together with the conveying mechanism and is located on both sides of the conveying direction of the conveying mechanism.

[0006] The manufactured bearings enter the intelligent testing device through the conveying mechanism. Guided by two sets of material guiding mechanisms, they move to the middle position of the conveying mechanism. As the bearings move towards the rotating mechanism, the distance measuring mechanism measures the distance between the bearings and the inspection station. The conveying mechanism adjusts the bearing conveying distance and the time it takes for the bearings to reach the inspection station accordingly. The rotating mechanism drives the testing mechanism to rotate at a constant speed above the conveying mechanism. When the testing mechanism rotates above the inspection station, it clamps the bearings for testing. After the test is completed, the testing mechanism also rotates to the discharge position of the conveying mechanism and puts the bearings back onto the conveying mechanism. During this process, the conveying mechanism and the rotating mechanism operate without stopping, so that each transported bearing can be continuously tested.

[0007] Furthermore, the conveying mechanism includes a frame, a support plate, a conveyor belt, a first drive assembly, a second drive assembly, and a first cylinder. The upper end of the frame is fastened to the material guiding mechanism, the upper end of the frame is fastened to the distance measuring mechanism, the frame is fastened to the support plate, the frame is fastened to the first drive assembly, the first drive assembly is in frictional contact with the conveyor belt, the frame and the second drive assembly are slidably connected, the second drive assembly is in frictional contact with the conveyor belt, the support plate is fastened to the first cylinder, and the output end of the first cylinder is fastened to the second drive assembly.

[0008] The guide mechanism is fixed by the frame, and the bearing is guided to the inspection position on the conveyor belt. The distance measuring mechanism is fixed by the frame and can measure the distance between the bearing and the inspection position. In the initial state, the linear speed of the second drive component and the first drive component are the same, and they drive the conveyor belt to rotate. The conveyor belt drives the bearing to move towards the inspection position. When the distance between the bearing and the inspection position is greater than the calibrated distance, the linear speed of the second drive component is increased to make the linear speed of the second drive component greater than that of the first drive component. Thus, the driving force of the second drive component on the conveyor belt becomes the main force driving the conveyor belt to rotate. The first drive component and the conveyor belt slip. Through the fixation of the output end of the first cylinder and the second drive component, the first cylinder can drive the second drive component to move up and down.

[0009] Furthermore, the first drive assembly includes a first drive gear, a first driven gear, a first motor, a first roller, a second roller, a first housing, a first idler roller, and a second idler roller. The frame and the first housing are fastened together. The first motor is housed inside the first housing. The output end of the first motor is fastened together with the first drive gear. The teeth of the first drive gear and the first driven gear mesh. The first driven gear and the first roller are fastened together. The first roller and the conveyor belt are in frictional contact. The first roller is covered by the first roller. The first roller and the first roller are rotatably connected. The first roller and the frame are fastened together. The conveyor belt and the second roller are in frictional contact. The second roller is covered by the second roller. The second roller and the second roller are rotatably connected. The second roller and the frame are fastened together.

[0010] The first motor outputs torque to drive the first drive gear to rotate. The first drive gear drives the first driven gear to rotate through tooth surface meshing. The first driven gear drives the first roller to rotate through a tight connection with the first roller. The first roller drives the conveyor belt to move by frictional contact with the conveyor belt. The first roller is installed between the frames through the first idler roller. There is a second roller on each side of the second drive assembly. The second rollers are in frictional contact with the conveyor belt, so the second rollers rotate with the movement of the conveyor belt. The second rollers are installed between the frames through the second idler roller.

[0011] Furthermore, the second drive assembly includes a second drive gear, a second driven gear, a second motor, a third roller, a second housing, a second cylinder, a third idler roller, and a fourth roller. The frame and the second housing are fastened together, the second housing and the second cylinder are fastened together, the output end of the second cylinder is fastened together with the second motor, the output end of the second motor is fastened together with the second drive gear, the teeth of the second drive gear and the second driven gear mesh, the second driven gear and the third roller are fastened together, the third roller and the conveyor belt are in frictional contact, the third idler roller is covered with a third roller, the third idler roller and the third roller are rotatably connected, the third idler roller and the second driven gear are rotatably connected, the third idler roller and the frame are slidably connected, the frame is provided with a sliding groove, the sliding groove and the third idler roller are slidably connected, and the surface roughness of the third roller is greater than that of the first roller.

[0012] The second motor outputs torque to drive the second drive gear to rotate. The second drive gear, through tooth meshing, drives the second driven gear to rotate. The second driven gear, through a fastened connection with the third roller, drives the third roller to rotate. The third roller, through friction contact with the conveyor belt, drives the conveyor belt to move. Initially, the linear velocities of the second drive gear and the first drive gear are the same. When the second drive gear rotates in the opposite direction to the first drive gear, the third roller also rotates in the opposite direction to the first roller, simultaneously driving the conveyor belt to rotate. When the distance between the bearing and the inspection station is greater than the calibrated distance, the linear velocity of the second drive gear is increased, making its linear velocity greater than that of the first drive gear. At the same time, the third idler roller drives the third roller to slide downward in the sliding groove, while the fourth roller on the other side rises. The third roller makes frictional contact with the conveyor belt, so that the driving force of the third roller on the conveyor belt is the main force driving the conveyor belt to rotate. The first roller and the conveyor belt slip, causing the bearing on the conveyor belt to move closer to the inspection station faster. When the distance between the bearing and the inspection station is less than the calibrated distance, the second drive gear rotates in the same direction as the first drive gear. At the same time, the third roller rises and the fourth roller falls. And because the surface roughness of the third roller is greater than that of the first roller, the conveyor belt rotates in the opposite direction, causing the bearing on the conveyor belt to move away from the inspection station.

[0013] Furthermore, the rotating mechanism includes a rotating disk, a support column, a first rotating shaft, a connecting plate, and a third motor. The third motor is fastened to the rotating disk, the output end of the third motor is fastened to the first rotating shaft, the first rotating shaft is rotatably connected to the rotating disk, the first rotating shaft is fastened to the support column, the support column is fastened to the frame, and several sets of connecting plates are provided below the rotating disk. The several sets of connecting plates are arranged in an equidistant array along the axial direction of the support column, and the several sets of connecting plates are fastened to the testing mechanism. The rotating disk is rotatably connected to the testing mechanism.

[0014] The connecting plate is fixed by a rotating disk. The third motor outputs torque to drive the rotating disk to rotate. The rotating disk can drive the testing mechanism to rotate at a certain speed, so that each testing mechanism can grab the bearing for testing when it reaches the position to be inspected. When it rotates to the position above the material discharge position of the conveyor belt, the test is completed and the bearing is put down. The conveyor belt drives the tested bearing to move to the subsequent position.

[0015] Furthermore, the testing mechanism includes a gripping assembly, a clamping assembly, a second rotating shaft, a sensor bracket, a vibration sensor, and a fourth motor. The gripping assembly is fastened to the connecting plate, the fourth motor is fastened to the rotating disk, the output end of the fourth motor is fastened to the second rotating shaft, the second rotating shaft is rotatably connected to the rotating disk, the second rotating shaft is rotatably connected to the connecting plate, two sets of clamping assemblies are provided below the connecting plate, the sensor bracket is fastened to an adjacent set of clamping assemblies, the sensor bracket is fastened to the vibration sensor, and the output end of the vibration sensor abuts against the inner ring of the bearing.

[0016] When the testing mechanism is positioned above the bearing, the gripping assembly grips the bearing and lifts it up, placing it in the middle of the clamping assembly. The clamping assembly fixes the outer ring of the bearing, and the inner ring of the bearing is fitted onto the second rotating shaft. During testing, the torque output by the fourth motor drives the second rotating shaft to rotate, which in turn drives the inner ring of the bearing to rotate. At the same time, the output end of the vibration sensor comes into contact with the inner ring of the bearing to measure the vibration of the inner ring of the bearing during rotation.

[0017] Furthermore, the gripping component includes a robotic arm and a gripper, and the clamping component includes a connecting block, a third cylinder, and a clamping plate. The upper end of the robotic arm is fastened to the connecting plate, the lower end of the robotic arm is fastened to the gripper, the connecting block is fastened to the connecting plate, the connecting block is fastened to the sensor bracket, the connecting block is fastened to the third cylinder, and the output end of the third cylinder is fastened to the clamping plate. The clamping plate is provided with an arc-shaped clamping groove.

[0018] When the testing mechanism is positioned above the bearing, the grippers grasp the bearing, and the rotating robotic arm raises the bearing. The outer ring of the bearing is clamped by the two side clamping plates, allowing the second rotating shaft to pass through the inner ring of the bearing. The clamping plates clamp and release via the third cylinder. The connecting block is fixed by the connecting plate, and the third cylinder is fixed by the lower end of the connecting block. The third cylinder is used to output displacement, driving the two opposing third cylinders to move in the center and clamp the outer ring of the bearing.

[0019] Furthermore, the material guiding mechanism includes a shaped plate and a connecting bracket. There are two connecting brackets, which are located on both sides of the conveyor belt in the conveying direction. The connecting brackets are fastened to the frame. The shaped plate is provided on the side of the connecting bracket closest to the conveyor belt. The shaped plate is provided with a guide slope and a guide plane in sequence along the conveying direction.

[0020] The connecting bracket is fixed by the frame, and the irregular shape is fixed by the connecting bracket. The two irregularly shaped plates arranged opposite each other guide the bearings entering the detection device. The guide slope first guides the irregularly arranged bearings at the feeding position to a horizontal line parallel to the conveyor belt, and the guide plane then guides the bearings to the detection station on the conveyor belt.

[0021] Furthermore, the ranging mechanism includes a rangefinder and an auxiliary support, the auxiliary support and the frame are fastened together, the auxiliary support and the rangefinder are fastened together, and the rangefinder's shooting direction is towards the conveyor belt.

[0022] The auxiliary support is fixed to the frame, and the rangefinder is fixed to the auxiliary support. The rangefinder measures the distance from the bearing to the workstation under inspection and transmits the data to the second motor. The second motor outputs torque to drive the second drive gear and the third roller to rotate. Whether the measured distance is greater than the calibrated distance determines whether the third roller rotates in the same direction or in the opposite direction to the first roller. When the measured distance is greater than the calibrated distance, the linear velocity of the third roller is made greater than that of the first roller, and the third roller rotates in the opposite direction to the first roller. This results in the driving force of the third roller on the conveyor belt being equal to that of the first roller. The main force driving the conveyor belt rotation is the slippage motion between the first roller and the conveyor belt, which causes the bearing on the conveyor belt to move closer to the inspection station more quickly. When the test distance is less than the calibrated distance, the third roller rotates in the same direction as the first roller. Since the surface roughness of the third roller is greater than that of the first roller, the conveyor belt rotates in the opposite direction, causing the bearing on the conveyor belt to move away from the inspection station. When the bearing moves away from the calibrated distance, the third roller rotates in the opposite direction to the first roller again, keeping their linear speeds consistent. This ensures that when the gripper reaches the top of the inspection station, the bearing has also moved to that position.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: When the bearing is transported by the conveyor belt, the bearing is first guided by the guiding mechanism, and then the distance from the bearing to the inspection station is measured by the rangefinder. In the initial state, the linear velocities of the third roller and the first roller are the same, and when the third roller rotates in the opposite direction to the first roller, it simultaneously drives the conveyor belt to rotate. When the measured distance is greater than the calibrated distance, the linear velocity of the third roller is made greater than that of the first roller. At the same time, the third idler roller drives the third roller to slide downward, and the fourth roller rises, so that the driving force of the third roller on the conveyor belt becomes the main force driving the conveyor belt to rotate. The first roller and the conveyor belt slip, making the bearing on the conveyor belt move closer to the inspection station faster. When the test distance is less than the calibrated distance... The third roller rotates in the same direction as the first roller. Because the surface roughness of the third roller is greater than that of the first roller, the conveyor belt rotates in the opposite direction. At the same time, the third roller rises and the fourth roller falls, causing the bearing on the conveyor belt to move away from the inspection station. When the bearing moves away to the calibrated distance, the third roller rotates in the opposite direction to the first roller again, keeping their linear speeds consistent. This ensures that when the gripper reaches the inspection station, the bearing has also moved to that position. After the gripper picks up the bearing, it is inspected. When the testing mechanism rotates with the rotating disc to the other end of the conveyor belt, the test is completed and the bearing is lowered. This intelligent inspection device uses the conveyor belt and robotic arm throughout the process, reducing labor costs. Moreover, the entire device runs continuously during bearing inspection, greatly improving inspection efficiency. Attached Figure Description

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.

[0027] Example: Figures 1-7 As shown, the present invention provides a technical solution for an intelligent testing device for bearing processing with automatic calibration function.

[0028] like Figure 1 As shown, an intelligent testing device for bearing processing with automatic calibration function is disclosed. The intelligent testing device includes a conveying mechanism 1, a rotating mechanism 2, a testing mechanism 3, a material guiding mechanism 4, and a distance measuring mechanism 5. The upper end of the conveying mechanism 1 and the lower end of the rotating mechanism 2 are fastened together. The rotating mechanism 2 and the testing mechanism 3 are fastened together. The testing mechanism 3 is provided with several groups, which are arranged in an equidistant array along the axial direction of the rotating mechanism 2. The material guiding mechanism 4 is provided with two groups, which are located at the feeding end of the conveying mechanism 1 and are symmetrically placed on both sides of the conveying mechanism 1. The distance measuring mechanism 5 is fastened to the conveying mechanism 1, and the distance measuring mechanism 5 and the rotating mechanism 2 are located on both sides of the conveying direction of the conveying mechanism 1, respectively.

[0029] The manufactured bearings enter the intelligent testing device through the conveying mechanism 1. Guided by two sets of guiding mechanisms 4, they move to the middle position of the conveying mechanism 1. As the bearings move towards the rotating mechanism 2, the distance measuring mechanism 5 measures the distance between the bearings and the inspection station. The conveying mechanism 1 adjusts the bearing conveying distance, and the time it takes for the bearings to reach the inspection station is adjusted accordingly. The rotating mechanism 2 drives the testing mechanism 3 to rotate at a constant speed above the conveying mechanism 1. When the testing mechanism 3 rotates above the inspection station, it clamps the bearings for testing. After the test is completed, the testing mechanism 3 also rotates to the discharge position of the conveying mechanism 1 and puts the bearings back on the conveying mechanism 1. During this process, the conveying mechanism 1 and the rotating mechanism 2 operate without stopping, so that each transported bearing can be continuously tested.

[0030] like Figures 1-2 As shown, the conveying mechanism 1 includes a frame 11, a support plate 12, a conveyor belt 13, a first drive assembly 14, a second drive assembly 15, and a first cylinder 16. The upper end of the frame 11 is fastened to the material guiding mechanism 4 and the distance measuring mechanism 5. The frame 11 is fastened to the support plate 12 and the first drive assembly 14. The first drive assembly 14 and the conveyor belt 13 are in frictional contact. The frame 11 and the second drive assembly 15 are slidably connected. The second drive assembly 15 and the conveyor belt 13 are in frictional contact. The support plate 12 and the first cylinder 16 are fastened to each other. The output end of the first cylinder 16 is fastened to the second drive assembly 15.

[0031] The guide mechanism 4 is fixed by the frame 11, and the bearing is guided by the guide mechanism 4 to the inspection position on the conveyor belt 13. The distance measuring mechanism 5 is fixed by the frame 11. The distance measuring mechanism 5 can measure the distance between the bearing and the inspection position. In the initial state, the linear speed of the second drive component 15 and the first drive component 14 are the same, and the conveyor belt 13 is driven to rotate. The conveyor belt 13 drives the bearing to move towards the inspection position. When the distance between the bearing and the inspection position is greater than the calibrated distance, the linear speed of the second drive component 15 is increased, so that the linear speed of the second drive component 15 is greater than the linear speed of the first drive component 14. Thus, the driving force of the second drive component 15 on the conveyor belt 13 is the main force that drives the conveyor belt 13 to rotate. The first drive component 14 and the conveyor belt 13 slip. Through the fixation of the output end of the first cylinder 16 and the second drive component 15, the first cylinder 16 can drive the second drive component 15 to move up and down.

The frame 11 and the first housing 146 are fastened together. The first motor 143 is housed inside the first housing 146. The output end of the first motor 143 is fastened together with the first drive gear 141. The first drive gear 141 and the first driven gear 142 mesh. Driven gear 142 is fastened to first roller 144. First roller 144 is in frictional contact with conveyor belt 13. First idler 147 is covered by first roller 144. First idler 147 and first roller 144 are rotatably connected. First idler 147 is fastened to frame 11. Conveyor belt 13 and second roller 145 are in frictional contact. Second idler 148 is covered by second roller 145. Second idler 148 and second roller 145 are rotatably connected. Second idler 148 is fastened to frame 11.

[0033] The first motor 143 outputs torque to drive the first drive gear 141 to rotate. The first drive gear 141 drives the first driven gear 142 to rotate through tooth surface meshing. The first driven gear 142 drives the first roller 144 to rotate through a tight connection with the first roller 144. The first roller 144 drives the conveyor belt 13 to rotate through frictional contact with the conveyor belt 13. The first roller 144 is installed between the frames 11 through the first idler roller 147. There is a second roller 145 on each side of the second drive assembly 15. The second roller 145 is in frictional contact with the conveyor belt 13, so the second roller 145 rotates with the movement of the conveyor belt 13. The second roller 145 is installed between the frames 11 through the second idler roller 148.

[0034] like Figures 3-5As shown, the second drive assembly 15 includes a second drive gear 151, a second driven gear 152, a second motor 153, a third roller 154, a second housing 155, a second cylinder 156, a third idler roller 157, and a fourth roller 158. The frame 11 and the second housing 155 are fastened together. The second housing 155 and the second cylinder 156 are fastened together. The output end of the second cylinder 156 is fastened together with the second motor 153. The output end of the second motor 153 is fastened together with the second drive gear 151.

[0035] The second motor 153 outputs torque to drive the second drive gear 151 to rotate. The second drive gear 151 drives the second driven gear 152 to rotate through tooth surface meshing. The second driven gear 152 drives the third roller 154 to rotate through a fastened connection with the third roller 154. The third roller 154 drives the conveyor belt 13 to move through friction contact with the conveyor belt 13. Initially, the linear velocities of the second drive gear 151 and the first drive gear 141 are the same. When the second drive gear 151 rotates in the opposite direction to the first drive gear 141, the third roller 154 will also rotate in the opposite direction to the first roller 144, simultaneously driving the conveyor belt 13 to rotate. When the distance between the bearing and the inspection station is greater than the calibrated distance, the linear velocity of the second drive gear 151 is increased to make the linear velocity of the second drive gear 151 greater than that of the first drive gear 141. The linear velocity of the third roller 157 drives the third roller 154 to slide downward in the sliding groove 111, while the fourth roller 158 on the other side rises. The third roller 154 makes frictional contact with the conveyor belt 13, so that the driving force of the third roller 154 on the conveyor belt 13 is the main force driving the conveyor belt 13 to rotate. The first roller 144 and the conveyor belt 13 slip, so that the bearing on the conveyor belt 13 moves closer to the inspection station faster. When the distance between the bearing and the inspection station is less than the calibrated distance, the second drive gear 151 rotates in the same direction as the first drive gear 141. At the same time, the third roller 154 rises and the fourth roller 158 falls. Since the surface roughness of the third roller 154 is greater than that of the first roller 144, the conveyor belt 13 rotates in the opposite direction, so that the bearing on the conveyor belt 13 moves away from the inspection station.

[0036] like Figure 6As shown, the rotating mechanism 2 includes a rotating disk 21, a support column 22, a first rotating shaft 23, a connecting plate 24, and a third motor 25.

The several sets of connecting plates 24 are fastened to the testing mechanism 3, and the rotating disk 21 is rotatably connected to the testing mechanism 3.

[0037] The connecting plate 24 is fixed by the rotating disk 21. The third motor 25 outputs torque to drive the rotating disk 21 to rotate. The rotating disk 21 can drive the testing mechanism 3 to rotate at a certain speed, so that each testing mechanism 3 can grab the bearing for testing when it reaches the upper position of the inspection station. When it rotates to the upper position of the conveyor belt 13, the test is completed and the bearing is put down. The conveyor belt 13 drives the tested bearing to move to the subsequent station.

[0038] like Figures 6-7 As shown, the testing mechanism 3 includes a gripping component 31, a clamping component 32, a second rotating shaft 33, a sensor bracket 34, a vibration sensor 35, and a fourth motor 36.

At the same time, the output end of the vibration sensor 35 abuts against the inner ring of the bearing to measure the vibration of the inner ring of the bearing during the rotation.

[0040] like Figure 7As shown, the gripping component 31 includes a robotic arm 311 and a gripper 312, and the clamping component 32 includes a connecting block 321, a third cylinder 322 and a clamping plate 323. The upper end of the robotic arm 311 is fastened to the connecting plate 24, the lower end of the robotic arm 311 is fastened to the gripper 312, the connecting block 321 is fastened to the connecting plate 24, the connecting block 321 is fastened to the sensor bracket 34, the connecting block 321 is fastened to the third cylinder 322, the output end of the third cylinder 322 is fastened to the clamping plate 323, and the clamping plate 323 is provided with an arc-shaped clamping groove.

[0041] When the testing mechanism 3 is positioned above the bearing, the gripper 312 grasps the bearing, and the rotating mechanical arm 311 raises the bearing. The outer ring of the bearing is clamped by the two side clamping plates 323, allowing the second rotating shaft 33 to pass through the inner ring of the bearing. The clamping plates 323 clamp and release the bearing via the third cylinder 322. The connecting plate 24 fixes the connecting block 321, and the lower end of the connecting block 321 fixes the third cylinder 322. The third cylinder 322 is used to output displacement, driving the two opposing third cylinders 322 to move in the center and clamp the outer ring of the bearing.

[0042] like Figure 1 As shown, the material guiding mechanism 4 includes a shaped plate 41 and a connecting bracket 42. There are two connecting brackets 42, which are located on both sides of the conveying direction of the conveyor belt 13. The connecting brackets 42 and the frame 11 are fastened together. The shaped plate 41 is provided on the side of the connecting bracket 42 near the conveyor belt 13. The shaped plate 41 is provided with a guide slope and a guide plane in sequence along the conveying direction.

[0043] The connecting bracket 42 is fixed by the frame 11, and the irregular plate 41 is fixed by the connecting bracket 42. The two irregular plates 41 arranged opposite each other guide the bearings entering the detection device. The guide slope first guides the irregularly arranged bearings at the feeding position to a horizontal line parallel to the conveyor belt 13, and the guide plane then guides the bearings to the detection station on the conveyor belt 13.

[0044] like Figure 4 As shown, the ranging mechanism 5 includes a rangefinder 51 and an auxiliary support 52. The auxiliary support 52 is fastened to the frame 11, and the rangefinder 51 is fastened to the auxiliary support 52. The shooting direction of the rangefinder 51 is towards the conveyor belt 13.

[0045] The auxiliary support 52 is fixed to the frame 11, and the rangefinder 51 is fixed to the auxiliary support 52. The rangefinder 51 measures the distance from the bearing to the inspection station and transmits the data to the second motor 153. The second motor 153 outputs torque to drive the second drive gear 151 and the third roller 154 to rotate. Whether the measured distance is greater than the calibrated distance determines whether the third roller 154 and the first roller 144 rotate in the same direction or in opposite directions. When the measured distance is greater than the calibrated distance, the linear velocity of the third roller 154 is greater than that of the first roller 144, and the third roller 154 rotates in the opposite direction to the first roller 144. This causes the third roller 154 to drive the conveyor belt 13. The force is the main force driving the conveyor belt 13 to rotate. The first roller 144 and the conveyor belt 13 slip, causing the bearing on the conveyor belt 13 to move closer to the inspection station more quickly. When the test distance is less than the calibrated distance, the third roller 154 rotates in the same direction as the first roller 144. Since the surface roughness of the third roller 154 is greater than that of the first roller 144, the conveyor belt 13 rotates in the opposite direction, causing the bearing on the conveyor belt 13 to move away from the inspection station. When the bearing moves away from the calibrated distance, the third roller 154 rotates in the opposite direction to the first roller 144 again, keeping their linear speeds consistent. This ensures that when the gripper 312 reaches above the inspection station, the bearing has also moved to that position.

[0046] Working principle of the invention: When the bearing is transported via the conveyor belt 13, it is first guided by the guiding mechanism 4, and then the distance from the bearing to the inspection station is measured by the rangefinder 51. Initially, the linear velocities of the third roller 154 and the first roller 144 are the same, and when the third roller 154 rotates in the opposite direction to the first roller 144, it simultaneously drives the conveyor belt 13 to rotate. When the measured distance is greater than the calibrated distance, the linear velocity of the third roller 154 is made greater than that of the first roller 144. At the same time, the third idler roller 157 drives the third roller 154 to slide downward, and the fourth roller 158 rises. Thus, the driving force of the third roller 154 on the conveyor belt 13 becomes the main force driving the rotation of the conveyor belt 13. The first roller 144 and the conveyor belt 13 slip, causing the bearing on the conveyor belt 13 to... The test mechanism moves closer to the inspection station more quickly. When the test distance is less than the calibrated distance, the third roller 154 rotates in the same direction as the first roller 144. Since the surface roughness of the third roller 154 is greater than that of the first roller 144, the conveyor belt 13 rotates in the opposite direction. At the same time, the third roller 154 rises and the fourth roller 158 falls, causing the bearing on the conveyor belt 13 to move away from the inspection station. When the bearing moves away from the calibrated distance, the third roller 154 rotates in the opposite direction to the first roller 144 again, keeping their linear speeds consistent. This ensures that when the gripper 312 reaches above the inspection station, the bearing also moves to that position. After the gripper 312 picks up the bearing, the bearing is tested. When the test mechanism 3 rotates with the rotating disk 21 to the other end of the conveyor belt 13, the test is completed and the bearing is lowered.
