Technical Field
[0001] This invention relates to the field of cam roller technology, specifically to a roller discharge device that can be used for defect detection. Background Technology
[0002] In modern industrial production, roller components such as cam rollers are widely used as key components in various mechanical equipment. Cam rollers are specially designed elements for cam mechanisms, their function being to convert the rotational motion of the cam into a predetermined motion pattern of the follower. The cam itself is a component with a specific profile; as it rotates, its profile curve pushes the roller in contact with it, thereby driving other components connected to the roller to operate in a preset manner.
[0003] Given the central role of cam rollers in complex mechanical systems, ensuring the high quality and reliability of these components is crucial. However, during the manufacturing process, factors such as material defects and machining errors may lead to quality problems in some rollers. If these problems are not detected and eliminated, they will directly affect the performance and lifespan of the entire mechanical system.

[0016] 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.
[0017] Please see Figure 1-12 The present invention provides a technical solution: a roller discharge device for defect detection, comprising a frame 1 for supporting the entire device, a drive unit 2 installed below the frame 1, a conveyor belt 3 installed inside the frame 1, the conveyor belt 3 being provided with the drive power required for conveying through the drive unit 2, baffles being provided on the inner walls of the frame 1 on both sides of the conveyor belt 3 to prevent materials on the conveyor belt 3 from falling off from both sides, one end of the conveyor belt 3 near the drive unit 2 being the input end, and the other end being the output end.
[0018] refer to Figure 1 and Figure 3 The conveyor belt 3 is provided with a first discharge chute 31, a second discharge chute 32, and a third discharge chute 33 in sequence from left to right along the conveying direction. A partition 4 is provided above the conveyor belt 3. A baffle 5 is hinged to the end of the partition 4 near the input end of the conveyor belt 3 by a rod. A motor is installed inside the rod. The baffle 5 is flipped by the motor. A partition 6 is also provided above the conveyor belt 3. A baffle 7 is hinged to the end of the partition 6 near the input end of the conveyor belt 3 by a rod. A motor is installed inside the rod. The baffle 7 is flipped by the motor. Partition 3 41 is provided at the end of partition 4 away from baffle 5, and partition 4 6 ... The first, second, and third channels are respectively equipped with a first guide plate group 8, a second guide plate group 10, and a third guide plate group 11. Each guide plate group consists of two plates converging towards the discharge chute along the direction from the input to the output end of the conveyor belt 3, with the convergence point forming the discharge port. One plate of the first guide plate group 8 is riveted to the inner wall of the frame 1, and the other plate is riveted to the inner wall of the partition 4. A distance sensor is installed near the discharge port of each plate in the first guide plate group 8. Figure 5 A sliding groove 81 is provided on the upper end face of the first guide plate group 8, and an adjustment component 9 is provided above the partition 4. Specifically, refer to Figure 5 The adjusting assembly 9 includes a positioning box 91, which is riveted to the top of the partition 4 via a plate. Two double-acting cylinders 92 are installed inside the positioning box 91. These double-acting cylinders 92 are double-acting cylinders with built-in brakes, which is existing technology; they can be driven by air pressure and locked by a brake. A connecting ring 93 is fixedly connected to the output end of the double-acting cylinder 92. A moving rod 94 is welded to the lower end of the connecting ring 93 and slidably connected within the slide groove 81. When the roller passes the first guide plate group 8, the conveying rollers of the conveyor belt 3 will pass through the discharge port of the first guide plate group 8. At this time, the rollers exert force on the two guide plates of the first guide plate group 8, opening its discharge port. The roller moves to a distance equal to the diameter of the roller. Simultaneously, under the action of the double-acting cylinder 92, the moving rod 94 slides within the slide groove 81. This distance parameter is fed back by the distance sensor. After the roller leaves the feed inlet, the first guide plate group 8 returns to its initial state under the action of the double-acting cylinder 92. During this process, the diameter of the roller can be fed back through the distance parameter, thereby accurately determining whether there is a size deviation in the roller, which is convenient for subsequent operations. When the double-acting cylinder 92 is set to the locked state, the opening size of the discharge port of the first guide plate group 8 can be set according to the actual situation. In this mode, rollers with a diameter exceeding this range will be blocked from entering the next process, thereby reducing the pressure on subsequent operations of the device.
[0019] Further, refer to Figure 1-2 A support frame 14 is fixedly connected to the top of the frame 1. The support frame 14 is a frame structure with vertical plates on both sides and a horizontal plate on the top. Viewing windows 141 are opened on the vertical plates on both sides of the support frame 14 for real-time observation of the material discharge on the conveyor belt 3. Several support members 26 are fixedly connected to the bottom surface of the horizontal plate of the support frame 14. The bottom ends of the support members 26 are riveted to the sides of partition 1 4, partition 2 6, partition 3 41 and partition 4 61 respectively, so as to realize the connection and support effect of the partitions. A camera (not shown in the figure) is also installed on the bottom surface of the horizontal plate of the support frame 14. It is mainly used to monitor the arrangement of the rollers on the channel, and the camera is equipped with image processing function. refer to Figure 4 , Figure 6 and Figure 7 The support frame 14 has a mounting groove 15 on the bottom surface of the horizontal plate, and a motor is installed in the mounting groove 15. Two support rods 16 are fixedly connected to the inner wall of the vertical plate of the support frame 14. A sliding column 17 is sleeved on the support rod 16, and a slide rail 171 is provided on the sliding column 17. A turntable 18 is connected to the bottom surface of the horizontal plate of the support frame 14 by a bearing. The turntable 18 is fixedly connected to the output shaft of the motor via a belt. A drive rod 19 is fixedly connected to the lower end of the turntable 18. The other end of the drive rod 19 is slidably connected to the slide rail 171 via a rod. After the motor drives, the turntable 18 rotates through belt transmission. At this time, the drive rod 19 will rotate. The back and forth rotation of the drive rod 19 causes the rod on it to slide back and forth in the slide rail 171, thereby causing the sliding column 17 to move back and forth on the support rod 16.
[0020] refer to Figure 8 A connecting rod 20 is fixedly connected to the center of the bottom surface of the sliding column 17. A mounting block 21 is fixedly connected to the other end of the connecting rod 20. A cylindrical cam 22 is connected to the inside of the mounting block 21 through a bearing. A closed-loop spiral V-shaped groove is opened around the surface of the cylindrical cam 22. A driven column 23 is provided on one side of the cylindrical cam 22. The driven column 23 is slidably connected in the groove of the cylindrical cam 22. A positioning rod 24 is welded to the side of the driven column 23 away from the cylindrical cam 22. A detection element 25 is threadedly connected to the bottom of the positioning rod 24, so that the detection element 25 and the sliding column 17 are moved synchronously. Furthermore, a hardness sensor is installed on the bottom surface of the detection component 25 to detect the hardness of the roller. In addition, a distance sensor 2 is also integrated inside the detection component 25 near the bottom surface. The cross-section of the detection component 25 is trapezoidal. After the detection component 25 is displaced, the roller in the discharge trough rolls and lifts the detection component 25 as it contacts the bottom inclined surface of the detection component 25 to the horizontal surface. At this time, the cylindrical cam 22 will rotate, and the hardness and diameter parameters of the roller are read by the hardness sensor and the distance sensor 2 respectively.
[0021] refer to Figure 2 as well as Figure 9-10 A mounting box 27 is fixedly connected to the outer wall of one side of the frame 1. A positioning frame 28 is fixedly connected inside the mounting box 27. A rotating component 29 is connected to the side of the positioning frame 28 away from the inner wall of the mounting box 27 by a bearing. A lever 30 is fixedly connected to the surface of the rotating component 29 away from the inner wall of the mounting box 27. A motor 4 is fixedly connected to the other side of the rotating component 29 through a coupling. The motor 4 is a bidirectional motor. A grooved wheel 34 is provided on one side of the lever 30. The grooved wheel 34 is rotatably connected to the positioning frame 28 through a rod. The grooved wheel 34 is a wheel structure with several U-shaped grooves around it. When the motor 4 starts, the rotating component 29 drives the lever 30 to rotate. The lever 30 is inserted into the U-shaped groove of the grooved wheel 34 in sequence, thereby causing the grooved wheel 34 to rotate intermittently. Furthermore, a rotating rod 35 is inserted through the middle of the grooved wheel 34, and the rotating rod 35 is inserted through the baffle of the frame 1. The rotating rod 35 is a hollow rod, and three adjusting members 36 are evenly fixedly connected to the rod body of the rotating rod 35. The three adjusting members 36 are respectively located in the first discharge groove 31, the second discharge groove 32 and the third discharge groove 33, so as to control the roller spacing in the discharge groove by realizing the intermittent rotation of the adjusting members 36. refer to Figure 11-12 The adjusting member 36 has a structure with several vertical plates arranged around a circumference. At the ends of the plates are several screen plates 361 at a certain angle. Each screen plate 361 contains a pressure sensor, which is battery-powered and outputs data via a wireless communication protocol to provide feedback on its contact with the rollers. The surface of each screen plate 361 is an inclined plane. Several air holes 362 are formed on the surface of one screen plate 361, and a passage is formed at the connection between the vertical plate corresponding to that screen plate 361 and the circumference. This passage is connected to the rotating rod 35, and a fan 38 is fixedly connected to the other end of the rotating rod 35. When the fan 38 is started, the generated air is directed into the rotating rod 35 and discharged through the passage connecting the air holes 362. This allows the screen plate 361 with the air holes 362 to clean dust and other debris from the discharge chute when it comes into contact with the discharge chute, preventing interference with the detection and arrangement of the rollers.
[0022] A controller 37 is fixedly connected to the top of the support frame 14. A buzzer is installed in the controller 37 to adjust the parameters of the device, provide status feedback, and issue an alarm as needed. Among them, drive unit 2, motor 1, motor 2, electric telescopic rod 1, electric telescopic rod 2, motor 3, distance sensor 1, hardness sensor, distance sensor 2, pressure sensor, motor 4, camera, double-acting cylinder 92, and fan 38 are all connected to controller 37 via signal.
[0023] A roller discharge device for defect detection offers two usage methods: Specifically, in Implementation Example 1, three channels are set to be turned on sequentially, and the turn-on time of each channel is t. Figure 1 As shown in the example, the first channel is in the open state, the second and third channels are in the closed state, the distance sensor is also in the closed state, the diameter and hardness parameters of the qualified roller are set by the controller 37, and the first guide plate group 8 is locked and in the maximum open state. When the drive unit 2 is started, the rollers are conveyed onto the conveyor belt 3 and enter the first channel. They are arranged one by one into the first discharge trough 31 by the first guide plate group 8. At the same time, the push plate 12 extends at a frequency p to push the rollers at the discharge port to prevent blockage. At this time, the detection piece 25 is moved back and forth in the first channel by the setting of the motor 3, so as to detect the diameter and hardness of the rollers in the first discharge trough 31. This is achieved by a distance sensor 1 installed in the first guide plate group 8, which forces the two plates of the guide plate group to separate as the roller passes by, until its outlet is opened to a distance matching the diameter of the roller. At this time, the distance sensor records this distance as the actual measured value of the roller diameter. If the actual measured value falls within the preset diameter standard range, the diameter parameter of the roller is considered to be qualified; otherwise, it is unqualified. At the same time, using the hardness sensor installed at the bottom of the detection component 25, when the roller rolls under the detection component 25 as the detection component 25 moves synchronously with the sliding column 17, the hardness sensor directly contacts and tests the hardness of the roller. If the measured hardness value meets the preset hardness range, the hardness parameter of the roller is considered qualified; otherwise, it is unqualified. Rollers with qualified parameters continue to be conveyed to the spacing adjustment component 36 for arrangement spacing adjustment. Rollers with unqualified parameters will be marked by the camera. When they are conveyed to the spacing adjustment component 36, the motor will reverse and lift the unqualified rollers. At this time, the lifted rollers will fall along the inclined surface of the screen plate 361 to a position outside the first discharge chute 31 on the conveyor belt 3, and will be rejected when conveyed to the output end of the conveyor belt 3. After time t, the first and third channels are closed, while the second channel is open. At this time, the rollers on conveyor belt 3 enter the second channel, pass through the second guide plate group 10, and are arranged in the second discharge chute 32. The same detection and rejection operations are performed, and the first push plate 12 assists in unblocking. After another time t, the third channel opens, and the rollers pass through the third guide plate group 11 and are arranged in the third discharge chute 33. The same detection and rejection operations are performed. It should be noted that when the third channel is conveying, the second push plate 13 assists in unblocking. After the third channel is completed, the second channel is used, again assisted by the second push plate 13. After the second channel is completed, the first channel is used, assisted by the first push plate 12, and so on. This process continues in sequence. Thus, while the rejection operation is being performed in the current channel, the arrangement and detection operations at the beginning of the next channel can begin, greatly improving the processing efficiency of the rollers.
[0024] Furthermore, the threshold for the defective quantity of a single channel roller is set to M, and the defective quantity of the roller reported by the test piece 25 during the actual testing process is m; When m≤M, it indicates that the defect rate of the rollers in this channel is normal; When m > M, it indicates that the defect rate of the rollers in this channel is high. At this time, the opening time t of this channel will be shortened, that is, the channel will be closed directly and the next channel will be opened for conveying. During the conveying process of the next channel, the defective quantity will be accumulated. When m continues to increase, it indicates that the detection part 25 is damaged. The controller 37 will shut down the drive unit 2 and issue an alarm to remind the operator to replace the detection part 25. If m does not continue to increase, it indicates that there are foreign objects in the discharge trough of the channel, causing the measurement results to deviate. At this time, the channel will no longer be opened until the rollers on the conveyor belt 3 have completed the inspection, and then the blower 38 will be turned on to clean the discharge trough.
[0025] Based on the above, the pressure sensor on the adjusting piece 36 can provide feedback on the conveying status of the rollers in the channel. When the frequency of the pressure received by the pressure sensor is higher than a set value p, the push plate is driven to push out the rollers in the discharge trough, so that they enter the discharge trough in the next opened channel for conveying, thereby relieving the conveying pressure in the channel. Furthermore, if the density of rollers in the channel is not improved under the assistance of the push plate, the channel opening time t is shortened accordingly, that is, the next channel is opened to arrange and detect the rollers.
[0026] This embodiment optimizes the processing flow by sequentially opening three channels and dynamically adjusting the working time of each channel. Each channel uses a specific guide plate to arrange the rollers, and uses a detection device to accurately detect the diameter and hardness of the rollers. Defective products are marked and physically rejected. The working status is automatically adjusted according to the number of defective rollers, ensuring production efficiency and quality control. The status of the rollers in the channel is monitored in real time by a camera, and the pusher action is intelligently adjusted to prevent blockage, further ensuring the smooth operation of the production line. This achieves efficient, flexible, and reliable automation of roller detection and discharge.
[0027] Example 2, which is a second method of using a roller discharge device that can be used for defect detection, in this case, only the first channel is in the open state, the second and third channels are in the closed state, and the first guide plate group 8 is set to the unlocked state, and the distance sensor is put into use. When the drive unit 2 is started, the roller is conveyed onto the conveyor belt 3 and enters the first channel. Guided by the first guide plate group 8, it enters the first discharge trough 31 in sequence. When the roller passes through the feed port, the distance parameter fed back by the distance sensor in the first guide plate group 8 is the diameter of the roller. The qualified value of the roller diameter is set to D, and the roller diameter fed back by the distance sensor is d. When d=D, the roller diameter is qualified, and the roller will continue to be conveyed in the first discharge trough 31; When d < D, the roller diameter is less than the qualified value. At this time, a second inspection is carried out by the inspection piece 25. After confirming that there is no error, the push plate 12 pushes the roller out into the second channel for conveying. When d > D, the roller diameter is less than the qualified value. Similarly, after the detection piece 25 confirms that there is no error, the push plate 12 pushes the roller out into the third channel for conveying. Furthermore, when the detection component 25 performs a second inspection, if the inspection result differs from that of the distance sensor, the defective roller will first be pushed out by the pusher plate 12 into the diameter matching channel fed back by the distance sensor. At the same time, the detection component 25 will be synchronously moved above the channel to inspect the roller again. If the inspection result is the same as that of the distance sensor, it indicates that there are impurities in the discharge trough interfering with the inspection result. At this time, the conveying of the roller to the conveyor belt 3 will be stopped, and the controller 37 will start the fan 38 to clean the relevant channel. If the inspection result is still different from that of the distance sensor, it indicates that the detection component 25 is damaged, and the controller 37 will issue an alarm to remind the operator to replace the detection component 25. At this point, the pressure sensor of the adjusting component 36 provides feedback on the conveying status of each channel, which can determine whether the diameter of the rollers produced in this batch is too large or too small. This allows for adjustment during the roller production process to prevent subsequent batches of rollers from having the same diameter defect.
[0028] This embodiment uses only the first channel for roller arrangement and preliminary inspection. A distance sensor measures the roller diameter and assigns the rollers to different channels for further processing based on the diameter. A secondary inspection mechanism for defective rollers is implemented. The consistency of the inspection results can be used to determine whether there is interference from impurities or damage to the inspection components, thereby taking appropriate cleaning or maintenance measures. This ensures accurate inspection and classification of each roller, effectively improving the quality control level of the product.
