Description

Technical Field

[0001] The invention relates to the technical field of bearing assembly, in particular to an automatic bearing assembly machine. Background Art

[0002] The automatic bearing assembly machine is a highly automated mechanical equipment specially used for the assembly process of bearings. The design of this machine aims to improve production efficiency, reduce manual operations, ensure assembly accuracy, and improve overall product quality. Its working principle is to transport each component to the assembly station through the feeding system, and then ensure the accurate positioning of the components through the positioning and clamping mechanism. Then the assembly mechanism assembles the components together according to the predetermined procedures and parameters. During the assembly process, the detection and feedback system monitors key parameters in real time to ensure the stability and consistency of the assembly quality. Finally, the control system controls and adjusts the entire process to achieve efficient and accurate assembly. During the final assembly process of the bearing, a certain amount of lubricating grease needs to be injected into the inside of the bearing to reduce the friction during its rotation. In the existing bearing assembly process, the lubricating grease is added to the inside of the bearing through a nozzle. During the oiling process, the bearing needs to be turned over so that an appropriate amount of lubricating grease is added to both sides. Since the lubricating grease has a certain fluidity, and its fluidity increases with increasing temperature, the added grease may be thrown out or flow out during the bearing flipping and subsequent transfer process, causing the conveyor table to be contaminated by the lubricating grease. In addition, when the bearing is being transported to the next process, its lower end is easily exposed to the lubricating grease and slips, resulting in a deviation between the final position of the bearing and the predetermined position, affecting the assembly accuracy of the bearing. For this reason, we propose an automatic bearing assembly machine. Summary of the invention

[0006] Preferably, limit rods are fixedly installed on both sides of the magnetic plate, and a guide groove for limiting the limit rod is provided inside the refueling bin, and the guide groove is designed in a "U" shape.

[0007] Preferably, a magnetic rod is fixedly installed at the lower end of the sliding plate, a circular groove for limiting the magnetic rod is provided in the refueling bin, and magnetic blocks that are magnetically attracted to the magnetic rod are fixedly installed on the inner wall of the initial end and the inner wall at the diagonal end of the circular groove.

[0008] Preferably, each of the oil injection devices is fixedly mounted with a plurality of telescopic rods for moving the balls in the bearings, each of the telescopic rods is fixedly mounted with a plurality of elastic strips, and each of the oil injection nozzles is provided with a plurality of positioning holes for limiting the elastic strips, and the positioning holes correspond one-to-one to the elastic strips.

[0009] Preferably, the lower end of each telescopic rod is located at the lower end of the oil injection nozzle, and the lower end of the telescopic rod is arranged in an arc shape, and the elastic force of the telescopic rod is smaller than the pulling force required for the elastic strip to deform.

[0010] Preferably, each of the electric shafts is symmetrically provided with two slide grooves, a guide block is slidably installed in each of the slide grooves, each of the guide blocks is fixedly connected to the corresponding clamping plate, and a first spring is fixedly connected to the inner wall of the slide groove, each of the fixed seats is provided with a limiting groove corresponding to the slide groove, the limiting groove is located above the electric shaft, and a second cylinder for pushing the clamping plate is fixedly installed on the fixed seat.

[0012] Preferably, the magnetic attraction force of the magnetic strip on the magnetic plate is greater than the elastic force of the second spring.

[0013] Preferably, the upper end of each of the limit strips is configured to be wedge-shaped to facilitate pushing the bearing.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention uses the first cylinder to push the limit card to move toward the bearing, and the magnetic rod moves vertically along the straight groove at the initial end of the round-shaped groove. After the first cylinder is extended, the magnetic rod will be attracted by the magnetic block at the diagonal position of the initial end of the round-shaped groove to move horizontally, and the limit card will drive the bearing to move to the next process. At the same time, the inclined surface of the wedge block cooperates with the inclined surface of the wedge plate, so that the wedge plate drives the limit bar to move downward. The first cylinder retracts to drive the magnetic rod to move vertically along the other straight groove of the round-shaped groove. The limit card retracts and no longer limits the bearing. The limit bar is extended upward by the elastic force of the telescopic column to limit the bearing again, so that the bearing is accurately located at a predetermined position, thereby improving the accuracy of the bearing processing process; 2. The present invention utilizes an oiling nozzle to drive the telescopic rod to move downward. The telescopic rod will first contact the ball in the bearing, causing the ball to deviate from the oil outlet of the oiling nozzle, thereby preventing the oiling nozzle from directly spraying the lubricating grease onto the ball, thereby reducing the situation in which the lubricating grease adheres to the oil outlet due to contact between the oil outlet and the ball. The lubricating grease is sprayed between two adjacent balls and is located deeper in the bearing. During the subsequent flipping and moving process, the lubricating grease is not easy to flow out.

[0015] 3. The present invention uses the gravity of the bearing to press the support member downward. If the lubricating grease in the bearing does not flow out or the amount of flow out is within a reasonable error, the weight of the bearing will cause the magnetic strip and the magnetic plate to be aligned or about to be aligned. The magnetic strip will generate sufficient magnetic attraction on the magnetic plate to put the magnetic plate in a retracted state. When the weight of the lubricating grease in the bearing is insufficient, the magnetic attraction generated by the magnetic strip on the magnetic plate is insufficient. The magnetic plate will extend a corresponding length according to the magnetic attraction of the magnetic strip on the magnetic plate. The third cylinder extends to drive the magnetic plate to move upward. If the magnetic strip generates sufficient magnetic attraction on the magnetic plate, the magnetic plate will move laterally along the bottom of the guide groove to the left vertical groove during the rising process, and finally retract to the initial end of the guide groove. If the magnetic attraction generated by the magnetic strip on the magnetic plate is insufficient, the magnetic plate will move laterally along the bottom of the guide groove to the right vertical groove during the rising process, and finally retract to the initial end of the guide groove. If the magnetic attraction generated by the magnetic strip on the magnetic plate is insufficient, the magnetic plate will move laterally along the bottom of the guide groove to the right vertical groove during the rising process, and the end of the magnetic plate will contact the inclined surface of the wedge, and the wedge drives the scraper to scrape the bearing on the support member to screen the bearings with insufficient internal lubricating grease.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-14The present invention provides a technical solution: an automatic bearing assembly machine, comprising a conveying table 1, a feeding device 2, an assembling mechanism 3, a riveting device 4, two cleaning devices 5, a measuring device 6, a refueling bin 7 and a detection device 49 fixedly installed on the conveying table 1 (the feeding device 2, the assembling mechanism 3, the riveting device 4, the cleaning device 5, the measuring device 6 and the detection device 49 are all existing known structures, so the present invention will not be described in detail), two capping devices 34 for capping both sides of the bearing are fixed in the refueling bin 7, and a grease-distributing device 35 for evenly distributing the lubricating grease in the bearing (the capping device 34 and the grease-distributing device 35 are also existing known structures, so the present invention will not be described in detail), and a refueling bin 7 is fixed with a plurality of capping devices 34 for capping both sides of the bearing. A first cylinder 8 is installed, a sliding plate 9 is slidably installed at the output end of the first cylinder 8, a plurality of limit cards 10 for conveying bearings are fixedly installed on the sliding plate 9, a magnetic rod 15 is fixedly installed at the lower end of the sliding plate 9, a circular groove 16 for limiting the magnetic rod 15 is provided in the refueling bin 7, a magnetic block 17 magnetically attracted to the magnetic rod 15 is fixedly installed on the inner wall of the initial end and the inner wall of the diagonal part of the initial end of the circular groove 16, a wedge block 11 is fixedly installed at the lower end of the sliding plate 9, a wedge plate 12 matching the wedge block 11 is slidably installed in the refueling bin 7, and the length of the wedge plate 12 is greater than the wedge block 11, a plurality of telescopic columns 14 are fixedly installed between the lower end of the wedge plate 12 and the inner wall of the refueling bin 7, and a plurality of telescopic columns 14 are fixedly installed on the upper end of the wedge plate 12 for conveying bearings. The limit strip 13 for limiting the bearing, the upper end of each limit strip 13 is set to be wedge-shaped for pushing the bearing. In the initial state, the first cylinder 8 is in a retracted state, the wedge block 11 does not limit the wedge plate 12, the limit strip 13 and the wedge plate 12 are pushed upward by the elastic force of the telescopic column 14, and the limit strip 13 extends upward to limit the bearing. When the first cylinder 8 is extended, it will push the sliding plate 9 and the limit card 10 to move toward the bearing, and the magnetic rod 15 moves vertically along the straight groove at the initial end of the circular groove 16. At the same time, the inclined surface of the wedge block 11 cooperates with the inclined surface of the wedge plate 12, so that the wedge plate 12 drives the limit strip 13 to move downward and compresses the telescopic column 14. After the first cylinder 8 is extended, the magnetic rod 15 will move to the corner of the circular groove 16 , and then it will be attracted by the magnetic block 17 at the diagonal position of the initial end of the circular groove 16 to move horizontally, and drive the sliding plate 9 to slide at the output end of the first cylinder 8. At the same time, the limit card 10 will drive the bearing to move to the next process. Since the length of the wedge plate 12 is greater than the wedge block 11, the wedge plate 12 is always limited by the wedge block 11. Then the first cylinder 8 will retract, driving the magnetic rod 15 to move vertically along the other straight groove of the circular groove 16. The limit card 10 retracts and no longer limits the bearing. At the same time, the wedge block 11 no longer limits the wedge plate 12. The limit bar 13 will be extended upward by the elastic force of the telescopic column 14 to limit the bearing again, so that the bearing is accurately located at the predetermined position, which improves the accuracy of the bearing processing process. After the first cylinder 8 is retracted,The magnetic rod 15 will be attracted by the magnetic block 17 at the initial end of the circular groove 16 again to move horizontally and reset. At this time, the bearings in the oil filling bin 7 are transported to the next corresponding process.

[0020] Two oil injection devices 21 are fixedly installed in the oil filling bin 7, and an oil injection nozzle 22 is slidably installed on each oil injection device 21. A plurality of telescopic rods 23 for moving the balls in the bearings are fixedly installed on each oil injection device 21, and a plurality of elastic strips 24 are fixedly installed on each telescopic rod 23. A plurality of positioning holes 25 for limiting the elastic strips 24 are provided on each oil injection nozzle 22, and the positioning holes 25 correspond to the elastic strips 24 one by one. The lower ends of the telescopic rods 23 are located at the lower ends of the oiling nozzles 22, and the lower ends of the telescopic rods 23 are arranged in an arc shape. The elastic force of the telescopic rods 23 is less than the pulling force required for the elastic strip 24 to deform. After the first cylinder 8 retracts, the oiling device 21 will start to move the oiling nozzles 22 downward. Since the initial elastic force of the telescopic rods 23 is less than the pulling force required for the elastic strip 24 to deform, the oiling nozzles 22 will drive the lower ends of the telescopic rods 23 to move downward. Since the lower ends of the telescopic rods 23 are located at the oiling nozzles 2 2, the telescopic rod 23 will first contact the ball in the bearing, and the lower end of the telescopic rod 23 is set in an arc shape. As the telescopic rod 23 moves downward, the ball of the bearing will rotate, causing the ball to deviate from the oil outlet of the oil injection nozzle 22, thereby preventing the oil injection nozzle 22 from directly spraying the lubricating grease onto the ball, reducing the situation where the oil outlet contacts the ball and causes the lubricating grease to adhere to the oil outlet, and the lubricating grease is sprayed between two adjacent balls, located at a deeper position in the bearing. In the subsequent flipping and moving process, the lubricating grease is not easy to flow out. After the ball position adjustment is completed, the telescopic rod 23 will stop moving first. As the oil injection nozzle 22 descends, the elastic strip 24 will deform and break away from the limit of the positioning hole 25, and then the elastic force of the telescopic rod 23 itself will drive it to move upward and reset, without affecting the oil output of the oil injection nozzle 22. After the oil injection is completed, the oil injection nozzle 22 will retract upward, and the elastic strip 24 will deform again and re-engage in the positioning hole 25.

[0021] Two fixed seats 32 are fixedly installed in the refueling bin 7, and an electric shaft 27 is rotatably installed on each fixed seat 32. Two clamping plates 28 for clamping bearings are arranged on each electric shaft 27. Two slide grooves 31 are symmetrically arranged on each electric shaft 27. A guide block 29 is slidably installed in each slide groove 31. Each guide block 29 is fixedly connected to the corresponding clamping plate 28, and a first spring 30 is fixedly connected to the inner wall of the slide groove 31. A limiting groove 33 corresponding to the slide groove 31 is arranged on each fixed seat 32, and the limiting groove 33 is located above the electric shaft 27. A second cylinder 26 for pushing the clamping plate 28 is fixedly installed on the fixed seat 32. In the initial state, the two slide grooves 31 are both in a vertical state. The guide block 29 in the lower slide groove 31 drives the lower clamping plate 28 to be located on the bearing conveying track, and the upper slide groove 31 is fixedly connected to the inner wall of the slide groove 31. The groove 31 is aligned with the limit groove 33, and the guide block 29 will drive the upper clamping plate 28 to move upward and enter the limit groove 33. After the first cylinder 8 retracts, the second cylinder 26 will also extend out, pushing the upper clamping plate 28 downward along the limit groove 33, and making the guide block 29 corresponding to the upper clamping plate 28 also enter the corresponding slide groove 31. At this time, the two clamping plates 28 will clamp the bearing, and then the second cylinder 26 will retract, and the electric shaft 27 will rotate 180 degrees, and the guide block 29 is limited by the fixed seat 32 and cannot extend out of the slide groove 31. The electric shaft 27 will drive the clamping plate 28 and the bearing to flip, and the lower clamping plate 28 will flip to the top, and the lower slide groove 31 will correspond to the limit groove 33. At this time, the upper clamping plate 28 will be pushed upward by the elastic force of the first spring 30, and the bearing will no longer be limited, and the bearing will complete the flipping.

[0022] A third cylinder 36 is fixedly installed in the refueling bin 7, and a fixed disk 37 is fixedly installed at the output end of the third cylinder 36. A pushing member 38 is fixedly installed on the upper end of the fixed disk 37, and a supporting member 39 is slidably installed on the pushing member 38. Elastic rods 40 are fixedly installed between the two sides of the supporting member 39 and the inner wall of the refueling bin 7, and a magnetic strip 41 is fixedly installed at the lower end of the supporting member 39. A magnetic plate 42 magnetically attracted to the magnetic strip 41 is slidably installed in the fixed disk 37, and a plurality of second springs 43 are fixedly connected between the magnetic plate 42 and the inner wall of the fixed disk 37. The magnetic attraction of the magnetic strip 41 to the magnetic plate 42 is greater than the elastic force of the second spring 43. A wedge-shaped member 46 cooperating with the end of the magnetic plate 42 is slidably installed in the refueling bin 7, and an elastic column 48 is fixedly connected between the wedge-shaped member 46 and the inner wall of the refueling bin 7. A scraper strip 47 for scraping the bearing down the conveying path is fixedly connected to the component 46, and limit rods 44 are fixedly installed on both sides of the magnetic plate 42. A guide groove 45 for limiting the limit rod 44 is arranged inside the refueling bin 7. The guide groove 45 is designed in a "U" shape. In the initial state, the third cylinder 36 remains in an extended state, pushing the fixed plate 37, the pushing member 38 and the supporting member 39 to move upward to support the bearing. At this time, since the magnetic attraction force of the magnetic strip 41 on the magnetic plate 42 is greater than the elastic force of the second spring 43, the magnetic plate 42 retracts into the fixed plate 37, and the limit rod 44 is located at the initial end of the upper left corner of the guide groove 45. The magnetic plate 42 does not limit the wedge 46, and the wedge 46 is pushed by the elastic force of the elastic column 48 to push the scraper strip 47, so that the scraper strip 47 is not on the bearing conveying track. On the upper side, it does not affect the transportation of the bearing. After the first cylinder 8 retracts, the third cylinder 36 will also retract, the fixed disk 37 no longer limits the support member 39, and the pushing member 38 no longer supports the bearing. The gravity of the bearing presses the support member 39 downward and compresses the elastic rod 40. When the fixed disk 37 moves downward, it will drive the magnetic plate 42 and the limiting rod 44 to move downward, and the limiting rod 44 will move vertically downward along the initial end of the guide groove 45. If the lubricating grease in the bearing does not flow out or the amount of flow out is within a reasonable error, the weight of the bearing will cause the support member 39 to drive the magnetic strip 41 to move downward, and align the magnetic strip 41 with the magnetic plate 42 or are about to align. The magnetic strip 41 will generate sufficient magnetic attraction on the magnetic plate 42, so that the magnetic plate 42 is in a retracted state. When the lubricating grease in the bearing does not flow out or the amount of flow out is within a reasonable error, the weight of the bearing will cause the support member 39 to drive the magnetic strip 41 to move downward, and align the magnetic strip 41 with the magnetic plate 42 or are about to align. The magnetic strip 41 will generate sufficient magnetic attraction on the magnetic plate 42, so that the magnetic plate 42 is in a retracted state. When the fat weight is insufficient, the magnetic attraction force generated by the magnetic strip 41 on the magnetic plate 42 is insufficient, and the magnetic plate 42 will extend a corresponding length according to the magnetic attraction force of the magnetic strip 41 on the magnetic plate 42. When the magnetic plate 42 extends, the limit rod 44 will move laterally along the bottom of the guide groove 45, and then the third cylinder 36 will extend to drive the fixed plate 37 and the magnetic plate 42 to move upward. If the magnetic strip 41 generates enough magnetic attraction on the magnetic plate 42, the magnetic plate 42 will move laterally along the bottom of the guide groove 45 to the left vertical groove during the rising process, and finally retract to the initial end of the guide groove 45. At this time, the end of the magnetic plate 42 does not contact the wedge 46. After the fixed plate 37 has risen, the pusher 38 and the support member 39 provide support for the bearing again, and the magnetic strip 41 will align with the magnetic plate 42 and generate enough magnetic attraction.Keep the magnetic plate 42 in the retracted state. If the magnetic attraction force generated by the magnetic strip 41 on the magnetic plate 42 is insufficient, the magnetic plate 42 will move horizontally along the bottom of the guide groove 45 to the right vertical groove during the rising process. At this time, the end of the magnetic plate 42 will contact the inclined surface of the wedge 46. During the rising process of the magnetic plate 42, the wedge 46 will drive the scraper 47 to scrape the bearing on the support 39, so that it leaves the bearing conveying track. The unqualified bearing will no longer be conveyed to the next process. After the third cylinder 36 is extended, the magnetic strip 41 will align with the magnetic plate 42 and generate sufficient magnetic attraction, so that the magnetic plate 42 is reset to the initial state along the upper horizontal groove of the guide groove 45. The wedge 46 is driven by the elastic force of the elastic column 48 to drive the scraper 47 to reset, effectively screening the bearings with insufficient internal lubricating grease.

[0023] A plurality of cleaning rollers 18 for cleaning the bearing conveying path are rotatably mounted on the sliding plate 9, and a gear 19 is fixedly mounted on each cleaning roller 18. A rack 20 meshing with the gear 19 is fixedly mounted in the refueling bin 7, and the rack 20 is located on the movement trajectory of the cleaning roller 18. When the first cylinder 8 is extended, the cleaning roller 18 will be driven to move to the bearing conveying trajectory, and the gear 19 will be meshed with the rack 20. When the sliding plate 9 slides, the meshing of the gear 19 and the rack 20 will drive the cleaning roller 18 to move and rotate at the same time, so as to clean the bearing conveying trajectory, reduce the influence of lubricating grease on the bearing conveying, and keep the bearing conveying trajectory clean. When the first cylinder 8 retracts, the cleaning roller 18 will also retract, and the gear 19 will no longer be meshed with the rack 20. When the sliding plate 9 is reset, the cleaning roller 18 and the gear 19 will also be driven to reset.

[0024] Specifically, the inner ring and outer ring of the bearing are first transported to the conveying platform 1 one by one through the feeding device 2, and then they are preliminarily demagnetized and cleaned by the first cleaning device 5, and then the inner ring, outer ring and ball of the bearing are assembled by the assembling mechanism 3, and then the balls are evenly distributed by the riveting device 4, and the balls are limited by the riveting gaskets, and then they are demagnetized and cleaned for the second time by the second cleaning device 5, and then the inner diameter, outer diameter and clearance of the bearing are measured by the measuring device 6, and then the bearing enters the refueling bin 7 to inject lubricating grease and cover, and finally the noise during the use of the bearing is detected by the detection device 49, and finally the qualified product is output, and after the bearing enters the refueling bin 7, when the first cylinder 8 extends, it will push the sliding plate 9 With the limit card 10 moving toward the bearing, the magnetic rod 15 moves vertically along the straight groove at the initial end of the circular groove 16. At the same time, the inclined surface of the wedge block 11 cooperates with the inclined surface of the wedge plate 12, so that the wedge plate 12 drives the limit bar 13 to move downward and compresses the telescopic column 14. After the first cylinder 8 is extended, the magnetic rod 15 will move to the corner of the circular groove 16, and then it will be attracted by the magnetic block 17 at the diagonal position of the initial end of the circular groove 16 to move horizontally, and drive the sliding plate 9 to slide at the output end of the first cylinder 8. At the same time, the limit card 10 will drive the bearing to the next process, and then the first cylinder 8 will retract, driving the magnetic rod 15 to move vertically along the other straight groove of the circular groove 16. The limit card 10 retracts and no longer limits the bearing. At the same time, the wedge block 11 no longer limits the wedge plate 12 limit, the limit strip 13 will be extended upward by the elastic force of the telescopic column 14 to limit the bearing again. After the first cylinder 8 is retracted, the magnetic rod 15 will be attracted by the magnetic block 17 at the initial end of the circular groove 16 again to move horizontally to reset. After the first cylinder 8 is retracted, the oil injection device 21 will be started to make the oil injection nozzle 22 move downward. Since the elastic force of the telescopic rod 23 is less than the pulling force required for the elastic strip 24 to deform, the oil injection nozzle 22 will drive the lower end of the telescopic rod 23 to move downward. Since the lower ends of the telescopic rod 23 are located at the lower end of the oil injection nozzle 22, the telescopic rod 23 will first contact the ball in the bearing, and the lower end of the telescopic rod 23 is arranged in an arc shape. As the telescopic rod 23 moves downward, the ball of the bearing will rotate, causing the ball to deviate from the oil outlet of the oil injection nozzle 22, avoiding The oil-free nozzle 22 directly sprays the lubricating grease onto the top of the ball. After the ball position adjustment is completed, the telescopic rod 23 will stop moving first. As the oil injection nozzle 22 descends, the elastic strip 24 will be deformed and disengage from the limit of the positioning hole 25, and then the elastic force of the telescopic rod 23 itself will drive it to move upward and reset without affecting the oil output of the oil injection nozzle 22. After the oil injection is completed, the oil injection nozzle 22 will retract upward, and the elastic strip 24 will be deformed again and re-engaged in the positioning hole 25. After the first cylinder 8 retracts, the second cylinder 26 will extend out, push the upper clamping plate 28 downward along the limit groove 33, and make the guide block 29 corresponding to the upper clamping plate 28 also enter the corresponding slide groove 31. At this time, the two clamping plates 28 will clamp the bearing, and then the second cylinder 26 will retract.At the same time, the electric shaft 27 will rotate 180 degrees, and the guide block 29 will be limited by the fixed seat 32 and cannot extend out of the slide slot 31. The electric shaft 27 will drive the clamping plate 28 and the bearing to flip over, and the lower clamping plate 28 will flip over to the top, and the lower slide slot 31 will correspond to the limiting slot 33. At this time, the upper clamping plate 28 will be pushed upward by the elastic force of the first spring 30 and will no longer limit the bearing. After the bearing completes the flipping, after the first cylinder 8 retracts, the third cylinder 36 will retract, the fixed plate 37 will no longer limit the support member 39, and the pushing member 38 will no longer support the bearing. The gravity of the bearing will press the support member 39 downward and compress the elastic rod 40, When the bearing 37 moves downward, it will drive the magnetic plate 42 and the limit rod 44 to move downward, and the limit rod 44 will move vertically downward along the initial end of the guide groove 45. If the lubricating grease in the bearing has not flowed out or the amount of flow out is within a reasonable error, the weight of the bearing will cause the support member 39 to drive the magnetic strip 41 to move downward, and align the magnetic strip 41 with the magnetic plate 42 or make it about to be aligned. The magnetic strip 41 will generate enough magnetic attraction on the magnetic plate 42 to make the magnetic plate 42 in a retracted state. When the weight of the lubricating grease in the bearing is insufficient, the magnetic attraction generated by the magnetic strip 41 on the magnetic plate 42 is insufficient, and the magnetic plate 42 will extend a corresponding length according to the magnetic attraction of the magnetic strip 41 on the magnetic plate 42. When the magnetic plate 42 is extended, the limit rod 44 will move vertically downward along the initial end of the guide groove 45. The positioning rod 44 will move laterally along the bottom of the guide groove 45, and then the third cylinder 36 will extend, driving the fixed disk 37 and the magnetic plate 42 to move upward. If the magnetic strip 41 generates sufficient magnetic attraction on the magnetic plate 42, the magnetic plate 42 will move laterally along the bottom of the guide groove 45 to the left vertical groove during the rising process, and finally retract to the initial end of the guide groove 45. At this time, the end of the magnetic plate 42 does not contact the wedge-shaped member 46. After the fixed disk 37 has risen, the pushing member 38 and the supporting member 39 provide support for the bearing again, and the magnetic strip 41 will align with the magnetic plate 42 and generate sufficient magnetic attraction to keep the magnetic plate 42 in a retracted state. If the magnetic attraction generated by the magnetic strip 41 on the magnetic plate 42 is insufficient, the magnetic plate 42 will be retracted. During the rising process of plate 42, it will move horizontally along the bottom of guide groove 45 to the right vertical groove. At this time, the end of magnetic plate 42 will contact the inclined surface of wedge 46. During the rising process of magnetic plate 42, wedge 46 will drive scraper 47 to scrape the bearing on support 39, so that it leaves the bearing conveying track. The unqualified bearing will no longer be conveyed to the next process. After the third cylinder 36 is extended, magnetic strip 41 will align with magnetic plate 42 and generate sufficient magnetic attraction, so that magnetic plate 42 will return to the initial state along the upper horizontal groove of guide groove 45. Wedge 46 is driven by the elastic force of elastic column 48 to drive scraper 47 to return to its original state, effectively screening bearings with insufficient internal lubricating grease.
