Description

Technical Field

[0001] The present application relates to the technical field of laser marking, and in particular to a laser marking assembly and a bearing laser marking device. Background Art

[0002] Laser marking is a technology that uses a high-energy-density laser beam to permanently mark the surface of various materials. In bearing manufacturing, laser marking is mainly used to engrave serial numbers, production dates, brand logos and other information to achieve product traceability, anti-counterfeiting and improve product quality.

[0003] In the prior art, the laser marking device includes a workbench and a laser head disposed on the workbench. The bearing to be laser marked is fixed on the workbench so that the surface of the bearing to be marked faces the laser head, and the surface of the bearing can be marked by the laser head. However, in actual applications of such laser marking devices, the connection and fixation between the bearing and the workbench takes a lot of time, and the disassembly and assembly process is cumbersome, which leads to the overall inefficiency of laser marking of the bearing. Therefore, further improvement is needed. Summary of the invention

[0004] In order to improve the overall efficiency of bearing marking, the present application provides a laser marking assembly and a bearing laser marking device.

[0005] In the first aspect, the laser marking assembly provided in this application adopts the following technical solution: A laser marking assembly comprises a workbench and a laser head, wherein the laser head is arranged on the workbench, and a marking station is formed below the laser head; the workbench is connected to a conveyor belt for conveying bearings, and a lifting seat is slidably installed on the workbench, and two clamping seats are slidably installed on the lifting seat, and the two clamping seats are respectively arranged on both sides of the marking station for clamping the flange of the bearing, and the side walls of the two clamping seats close to each other are provided with embedded arc grooves for the bearing flange to be embedded; the lifting seat is provided with a driving component for driving the two clamping seats to approach or move away from each other.

[0006] By adopting the above technical solution, when the surface of the bearing is laser marked, the bearing is transported to the marking station through the conveyor belt, and then the two clamping seats are forced to approach each other through the driving component to clamp the flange of the bearing. The setting of the embedded arc groove can improve the connection stability between the bearing flange and the clamping seat. After the two clamping seats clamp the bearing, the lifting seat is driven to lift a certain distance to lift the bearing off the surface of the conveyor belt, thereby reducing the possibility of the conveyor belt causing shaking of the bearing during the marking process of the bearing, thereby improving the quality of laser marking. After the marking is completed, the lifting seat is driven to move down and force the two clamping seats to move away from each other, so that the marked bearing can be output outward through the conveyor belt, which greatly improves the overall efficiency of bearing marking.

[0007] Optionally, the driving assembly includes a connecting arm and a driving cylinder. There are two connecting arms, and both of the two connecting arms are slidably mounted on the lifting seat. The two connecting arms are arranged corresponding to the two clamping seats, and each clamping seat is arranged on the corresponding connecting arm. The clamping seat is slidably mounted on the lifting seat through the corresponding connecting arm; the cylinder body of the driving cylinder is connected to the lifting seat, and the driving cylinder has two piston rods, and the two piston rods of the driving cylinder are respectively connected to the two connecting arms.

[0008] By adopting the above technical solution, after the bearing is conveyed to the marking station, the driving cylinder is forced to make the two connecting arms approach each other, so that the two clamping seats can jointly clamp the flange of the bearing, improving the disassembly and assembly convenience between the bearing and the workbench.

[0009] Optionally, each connecting arm is connected with a rotary cylinder. The cylinder body of the rotary cylinder is fixed on the side wall of the connecting arm, and the rotating end of the rotary cylinder is connected to the clamping seat corresponding to the connecting arm. The clamping seat is rotatably mounted on the connecting arm through the rotary cylinder.

[0010] By adopting the above technical solution, with the setting of the rotary cylinder, after the two clamping seats clamp the bearing, the rotary cylinder can be forced to make the clamping seat rotate, so that the "turning over" of the bearing can be realized, enabling the laser head to perform laser marking on different surfaces of the bearing according to actual needs and improving the adaptability of the overall structure.

[0011] Optionally, the driving assembly includes a connecting arm, an installation ring, a rotating ring, a guiding member and a driving member. There are two connecting arms, and both of the two connecting arms are mounted on the lifting seat; the installation ring is arranged between the two connecting arms, and an installation groove is formed on the inner peripheral wall of the installation ring. Each clamping seat is provided with a sliding block, and the sliding block is slidably mounted on the inner wall of the installation groove; the rotating ring is rotatably connected in the installation groove and is coaxially arranged with the installation ring. The guiding member is arranged between the rotating ring and the sliding block. When the rotating ring rotates, the guiding member forces the sliding block to displace along the radial direction of the installation ring; the driving member is arranged on the connecting arm to drive the rotating ring to rotate.

[0012] By adopting the above technical solution, after the bearing is conveyed to the marking station by the conveyor belt, the lifting seat is forced to move downward so that the installation ring is sleeved on the outer peripheral side of the bearing. Then, the driving member is forced to make the rotating ring rotate. Under the action of the guiding member, the sliding block can slide towards the center of the installation ring to clamp and fix the flange of the bearing. Then, the lifting seat is driven to rise, and the bearing can be lifted off the conveyor belt, facilitating the laser head to perform laser marking on the surface of the bearing.

[0013] Optionally, the guiding member includes two guiding columns disposed on the rotating ring, the two guiding columns are correspondingly arranged with the two clamping seats, and a guiding groove for the corresponding guiding column to be inserted is formed on the side wall of each clamping seat; the two ends of the guiding groove respectively form a first point and a second point, and the distance from the first point to the center of the mounting ring is greater than the distance from the second point to the center of the mounting ring; when the rotating ring rotates and forces the guiding column to slide from the second point towards the first point, the two clamping seats approach each other.

[0014] By adopting the above technical solution, when clamping the bearing, the rotating ring is driven to rotate, so that the guiding column slides from the second point towards the first point. The rotating ring pushes the inner wall of the guiding groove through the guiding column, thereby driving the clamping seat to slide towards the center of the mounting ring, so that the clamping seat can clamp and fix the flange of the bearing. After the bearing is marked, the rotating ring is driven to rotate in the reverse direction, so that the guiding column can slide from the first point towards the second point, thereby forcing the two clamping seats to move away from each other to loosen the bearing, improving the operation convenience of the overall structure.

[0015] Optionally, a sliding groove is formed on the inner wall of the mounting groove, the two ends of the sliding groove extend along the radial direction of the mounting ring, and the sliding block is slidably mounted in the sliding groove; a rotating groove is formed on the inner wall of the mounting groove, the rotating groove is arc-shaped, and the virtual central axis of the rotating groove coincides with the central axis of the mounting ring; one end of the rotating groove is communicated with one end of the sliding groove, and when the guiding column slides from the second point to the first point, the sliding block slides into the rotating groove.

[0016] By adopting the above technical solution, the setting of the sliding groove enables the sliding block to slide along the radial direction of the mounting ring when the guiding column slides in the guiding groove, so that the clamping seat clamps or loosens the bearing. When the guiding column slides from the second point to the first point (that is, when the clamping seat clamps the bearing), at this time the sliding block slides into the rotating groove, and the rotating ring is continuously driven to rotate. The rotating ring can drive the sliding block to rotate into the rotating groove, so that the clamping seat can drive the bearing to rotate by a certain angle around the central axis of the mounting ring. By rotating the bearing by a certain angle to cooperate with the laser head, the displacement of the laser head for laser marking can be greatly reduced, improving the adaptability of the overall structure.

[0017] Optionally, the driving member includes a rotating shaft, a bevel gear, a bevel gear ring and a driving motor. One end of the rotating shaft is rotatably connected to one of the connecting arms, and the other end extends into the mounting groove and is coaxially connected to the bevel gear. The bevel gear ring is coaxially arranged on the surface of the rotating ring, and the bevel gear and the bevel gear ring are meshed and driven; the driving motor is arranged on one of the connecting arms, and the output shaft of the driving motor is coaxially connected to the rotating shaft.

[0018] By adopting the above technical solution, the driving motor drives the rotating shaft to rotate. Under the action of the bevel gear and the bevel gear ring, the rotation can drive the rotation around its own central axis, so as to drive the two clamping seats to approach or move away from each other.

[0019] Optionally, a first rotating rod is connected to the outer peripheral wall of the mounting ring. The first rotating rod is rotatably connected to the connecting arm, and the mounting ring is rotatably mounted on the connecting arm through the first rotating rod; the workbench is provided with a turning assembly for driving the first rotating rod to rotate.

[0020] By adopting the above technical solution, through the setting of the turning assembly, the "turning over" of the bearing is realized, so that the laser head can perform laser marking on different surfaces of the bearing according to actual needs, improving the adaptability of the overall structure.

[0021] Optionally, a second rotating rod is rotatably mounted on the connecting arm. The turning assembly includes an eccentric rod, a guiding plate and a synchronizing member. The eccentric rod is arranged on the outer peripheral wall of one end of the second rotating rod, and the eccentric rod is eccentrically arranged with the second rotating rod; the guiding plate is arranged on the workbench, and a guiding groove for the eccentric rod to be embedded is formed on the plate surface of the guiding plate; the guiding groove has a straight section and an inclined section. One end of the straight section is communicated with one end of the inclined section. The end of the straight section far from the inclined section forms a third position point, and the end of the straight section close to the inclined section forms a fourth position point. The end of the inclined section far from the straight section forms a fifth position point; when the eccentric rod slides from the third position point to the fourth position point, the mounting ring lifts the bearing off the conveyor belt; when the eccentric rod slides from the fourth position point to the fifth position point, the mounting ring drives the bearing to turn over and forces the central axis of the bearing to be parallel to the surface of the conveyor belt; the synchronizing member is arranged between the first rotating rod and the second rotating rod to drive the first rotating rod and the second rotating rod to rotate synchronously.

[0022] By adopting the above technical solution, under normal conditions, the eccentric rod is located at the fourth position. After the bearing is conveyed to the marking station, the lifting seat is driven to move downward, so that the mounting ring is sleeved on the outer peripheral side of the bearing (at this time, the eccentric rod slides from the fourth position to the third position). Then, the bearing is clamped and fixed by the clamping seat. Next, the lifting seat is forced to rise to lift the bearing off the conveyor belt (at this time, the eccentric rod slides back to the fourth position). When laser marking is required on the outer peripheral wall of the bearing flange, the lifting seat can be driven to continue rising, forcing the eccentric rod to slide from the fourth position to the fifth position. Under the guidance of the inclined section, the eccentric rod drives the first rotating rod and the second rotating rod to rotate, so as to force the central axis of the bearing to be parallel to the surface of the conveyor belt. At this time, the outer peripheral wall of the bearing flange can be marked. If the bearing needs to be turned over, the lifting seat can be driven to descend, forcing the eccentric rod to slide from the fifth position back to the fourth position, and the turning over of the bearing can be realized. The achieved effect is that the bearing can be turned over, so that different surfaces of the bearing flange face the laser head for laser marking, or the peripheral wall of the bearing flange can face the laser head to mark the peripheral wall of the bearing flange. Specifically, the turning position of the bearing is adaptively adjusted according to actual needs, greatly improving the flexibility of the overall structure.

[0023] In a second aspect, a bearing laser marking device provided by the present application adopts the following technical solution: A bearing laser marking device includes a marking machine table and the above-mentioned laser marking assembly.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the arrangement of the two clamping seats, when laser marking the surface of the bearing, the bearing is conveyed to the marking station by the conveyor belt. Then, the two clamping seats are forced to approach each other by the driving assembly to clamp the flange of the bearing. The arrangement of the embedded arc grooves can improve the connection stability between the bearing flange and the clamping seat. After the two clamping seats clamp the bearing, the lifting seat is driven to rise a certain distance to lift the bearing off the surface of the conveyor belt, reducing the possibility of the bearing shaking caused by the conveyor belt during the marking process of the bearing, thereby improving the laser marking quality. After the marking is completed, the lifting seat is driven to move downward and the two clamping seats are forced to move away from each other, and the marked bearing can be output outward by the conveyor belt, greatly improving the overall marking efficiency of the bearing; 2. By setting the guide posts, when clamping the bearing, the rotating ring is driven to rotate, causing the guide posts to slide from the second position towards the first position. The rotating ring pushes against the inner wall of the guide groove through the guide posts, thereby driving the clamping seat to slide towards the center of the mounting ring, enabling the clamping seat to clamp and fix the flange of the bearing. After the bearing is marked, driving the rotating ring to rotate in the reverse direction can cause the guide posts to slide from the first position towards the second position, forcing the two clamping seats to move away from each other to release the bearing, improving the operational convenience of the overall structure; 3. By setting the rotating groove, when the guide posts slide from the second position to the first position (i.e., when the clamping seat clamps the bearing), at this time the sliding block slides into the rotating groove. Continuing to drive the rotating ring to rotate, the rotating ring can drive the sliding block to turn into the rotating groove, so that the clamping seat can drive the bearing to rotate by a certain angle around the central axis of the mounting ring. By rotating the bearing by a certain angle to cooperate with the laser head, the displacement of the laser head for laser marking can be significantly reduced, improving the adaptability of the overall structure.

[0027] The following is combined with Figures 1 - 9 to further elaborate on this application in detail.

[0028] Embodiment 1: The embodiment of this application discloses a laser marking general assembly.

[0029] Referring to Figure 1 and Figure 2 , a laser marking general assembly includes a workbench 1 and a laser head. The laser head (the laser head is a prior art, and its structure will not be elaborated too much here and is not shown in the figure) is slidably mounted on the workbench 1, and a marking station 11 is formed below the laser head. The workbench 1 is connected with a conveyor belt 2 for conveying bearings. Two positioning strips 21 are installed above the conveyor belt 2. The two positioning strips 21 are arranged at intervals along the width direction of the conveyor belt 2 and form a conveyor channel 22 for the bearings to pass through.

[0030] A blocking block 23 is slidably mounted on the workbench 1. The blocking block 23 is located at the output port of the conveyor channel 22 to block the bearings. In this embodiment, the driving mode of the blocking block 23 is cylinder driving, that is, the blocking block 23 is driven by a cylinder to slide along the width direction of the conveyor belt 2, so that the blocking block 23 can control the opening and closing of the output port of the conveyor channel 22.

[0031] Referring to Figure 1 and Figure 3 and Figure 4, a lifting seat 3 is installed inside the workbench 1. The lifting seat 3 is slidably installed on the workbench 1 to be able to lift. The workbench 1 is equipped with a lifting cylinder 32. The cylinder block of the lifting cylinder 32 is fixedly installed at the bottom of the workbench 1, and the piston rod of the lifting cylinder 32 is fixedly connected to the lifting seat 3. When the piston rod of the lifting cylinder 32 extends outwards, the lifting seat 3 is lifted. A lifting groove 12 for avoiding the lifting seat 3 is formed on the tabletop of the workbench 1, and the lifting groove 12 is directly opposite to the marking station 11; two clamping seats 31 are slidably installed on the lifting seat 3. The two clamping seats 31 are respectively arranged on both sides of the marking station 11 for clamping the flange of the bearing, and the mutually approaching side walls of the two clamping seats 31 are both provided with embedding arc grooves 311 for the bearing flange to be embedded.

[0032] It should be noted that in this embodiment, a blocking block 23 (not shown in the figure) also needs to be slidably arranged at the rear end of the marking station 11 (that is, the side of the marking station 11 far from the conveying channel 22), and the driving mode of this blocking block 23 is also driven by a cylinder. This blocking block 23 is used to block the bearing conveyed by the conveying channel 22 to position the bearing at the marking station 11.

[0033] Refer to Figure 3 、 Figure 4 , the lifting seat 3 is provided with a driving assembly 4 for driving the two clamping seats 31 to approach or separate from each other. In this embodiment, the driving assembly 4 includes a connecting arm 41 and a driving cylinder 42. There are two connecting arms 41. The two connecting arms 41 are both slidably installed on the lifting seat 3. The two connecting arms 41 are arranged corresponding to the two clamping seats 31. Each clamping seat 31 is arranged on the corresponding connecting arm 41, and the clamping seat 31 is slidably installed on the lifting seat 3 through the corresponding connecting arm 41.

[0034] The driving cylinder 42 can be a double-rod cylinder. The cylinder block of the driving cylinder 42 is fixedly connected to the lifting seat 3. The driving cylinder 42 has two piston rods, and the two piston rods of the driving cylinder 42 are respectively fixedly connected to the two connecting arms 41 to drive the two connecting arms 41 to approach or separate from each other; in other embodiments, the two connecting arms 41 can be respectively equipped with individual cylinders for control.

[0035] Refer to Figure 3 、 Figure 4 , in this embodiment, each connecting arm 41 is equipped with a rotary cylinder 411. The cylinder block of the rotary cylinder 411 is fixedly installed on the upper side wall of the connecting arm 41. The rotating end of the rotary cylinder 411 is connected to the clamping seat 31 corresponding to the connecting arm 41, and the clamping seat 31 is rotatably installed on the connecting arm 41 through the rotary cylinder 411.

[0036] The implementation principle of Embodiment 1 of this application is as follows: When laser marking the surface of a bearing, the bearing is conveyed to the marking station 11 through the conveyor belt 2. Then, the two connecting arms 41 are driven to approach each other so that the two clamping seats 31 can clamp the flange of the bearing. The provision of the embedded arc groove 311 can improve the connection stability between the bearing flange and the clamping seat 31. After the two clamping seats 31 clamp the bearing, the lifting seat 3 is driven to lift a certain distance to lift the bearing off the surface of the conveyor belt 2, reducing the possibility of the conveyor belt 2 causing shaking of the bearing during the laser marking process, thereby improving the laser marking quality.

[0037] After the marking is completed, the lifting seat 3 is driven to move downward and the two clamping seats 31 are forced to move away from each other, and then the marked bearing can be output outward through the conveyor belt 2, greatly improving the overall efficiency of bearing marking. With the provision of the rotary cylinder 411, after the two clamping seats 31 clamp the bearing, the clamping seat 31 can be forced to rotate by the rotary cylinder 411, so that the bearing can be "turned over", enabling the laser head to perform laser marking on different surfaces of the bearing according to actual needs, improving the adaptability of the overall structure.

[0038] Embodiment 2: This application embodiment discloses a laser marking assembly.

[0039] The difference between the laser marking assembly disclosed in this application embodiment and Embodiment 1 lies in: Referring to Figure 5 、 Figure 6 In this embodiment, the driving assembly 4 includes connecting arms 41, an installation ring 43, a rotating ring 44, a guiding member, and a driving member. There are two connecting arms 41, and both of the two connecting arms 41 are fixedly installed on the lifting seat 3; the installation ring 43 is installed between the two connecting arms 41. An installation groove 431 is provided on the inner peripheral wall of the installation ring 43. The installation groove 431 is annular around the central axis of the installation ring 43. One end of each clamping seat 31 extends into the installation groove 431 and is fixedly connected with a sliding block 312. A sliding groove 432 is provided on the inner wall of the installation groove 431. The two ends of the sliding groove 432 extend along the radial direction of the installation ring 43. The sliding block 312 is slidably installed in the sliding groove 432, and the clamping seat 31 is slidably installed in the sliding groove 432 of the installation ring 43 through the sliding block 312 so as to be able to slide along the radial direction of the installation ring 43.

[0040] Referring to Figure 5 、 Figure 7, the rotating ring 44 is rotatably connected in the mounting groove 431 and is coaxially arranged with the mounting ring 43. The rotating ring 44 is located on the side of the clamping seat 31 away from the sliding block 312. The guiding member is arranged between the rotating ring 44 and the sliding block 312. When the rotating ring 44 rotates, the guiding member forces the sliding block 312 to displace along the radial direction of the mounting ring 43. In this embodiment, the guiding member includes two guiding columns 45, and both of the two guiding columns 45 are fixedly installed on the surface of the rotating ring 44 close to the clamping seat 31, and the two guiding columns 45 are arranged corresponding to the two clamping seats 31.

[0041] A guiding groove 313 for the corresponding guiding column 45 to be embedded is formed on the side wall of each clamping seat 31; two ends of the guiding groove 313 respectively form a first point 314 and a second point 315, and the distance from the first point 314 to the center of the mounting ring 43 is greater than the distance from the second point 315 to the center of the mounting ring 43; when the rotating ring 44 rotates and forces the guiding column 45 to slide from the second point 315 towards the first point 314, the two clamping seats 31 approach each other, and when the rotating ring 44 rotates in the reverse direction and forces the guiding column 45 to slide from the first point 314 towards the second point 315, the two clamping seats 31 move away from each other to loosen the bearing.

[0042] Refer to Figure 5 , Figure 7 , a driving member is arranged on the connecting arm 41 to drive the rotating ring 44 to rotate. The driving member includes a rotating shaft 46, a bevel gear 47, a bevel gear ring 48 and a driving motor 49. One end of the rotating shaft 46 is rotatably connected to one of the connecting arms 41, and the other end extends into the mounting groove 431 and is coaxially connected to the bevel gear 47. The bevel gear ring 48 is coaxially fixed on the surface of the rotating ring 44, and the bevel gear 47 and the bevel gear ring 48 are meshed and driven; the driving motor 49 is fixedly installed on one of the connecting arms 41, and the output shaft of the driving motor 49 is coaxially connected to the rotating shaft 46. In this embodiment, the driving motor 49 is a servo motor (that is, the output shaft of the driving motor 49 can rotate forward and backward).

[0043] Refer to Figure 5 , Figure 7 , Figure 8 , a first rotating rod 434 is fixedly connected to the outer peripheral wall of the mounting ring 43. The first rotating rod 434 and the rotating shaft 46 are coaxially arranged. The first rotating rod 434 is rotatably connected to the connecting arm 41. The mounting ring 43 is rotatably mounted on the connecting arm 41 through the first rotating rod 434; the workbench 1 is provided with a flipping assembly 5 for driving the first rotating rod 434 to rotate. A second rotating rod 412 is rotatably mounted on the connecting arm 41. The flipping assembly 5 includes an eccentric rod 51, a guiding plate 52 and a synchronizing member. The eccentric rod 51 is fixedly installed on the outer peripheral wall of one end of the second rotating rod 412, and the eccentric rod 51 is eccentrically arranged with respect to the second rotating rod 412 (that is, the eccentric rod 51 can perform "revolution" around the central axis of the second rotating rod 412).

[0044] The guide plate 52 is vertically arranged, the lower end of the guide plate 52 is fixedly installed on the surface of the workbench 1, and a guide groove 53 for the eccentric rod 51 to be embedded is formed on the plate surface of the guide plate 52; the guide groove 53 has a straight section 531 and an inclined section 532, the inclined section 532 is located above the straight section 531, and one end of the straight section 531 is communicated with one end of the inclined section 532; the end of the straight section 531 far from the inclined section 532 forms a third position point 533, the end of the straight section 531 close to the inclined section 532 forms a fourth position point 534, and the end of the inclined section 532 far from the straight section 531 forms a fifth position point 535; when the eccentric rod 51 slides from the third position point 533 to the fourth position point 534, the mounting ring 43 lifts the bearing away from the conveyor belt 2; when the eccentric rod 51 slides from the fourth position point 534 to the fifth position point 535, the mounting ring 43 drives the bearing to turn and forces the central axis of the bearing to be parallel to the surface of the conveyor belt 2.

[0045] Refer to Figure 5 、 Figure 7 A synchronizing member is arranged between the first rotating rod 434 and the second rotating rod 412 to drive the first rotating rod 434 and the second rotating rod 412 to rotate synchronously. In this embodiment, the synchronizing member includes a first gear 54 and a second gear 55. The first gear 54 is coaxially fixed on the outer peripheral wall of the first rotating rod 434, the second gear 55 is coaxially fixed on the outer peripheral wall of the second rotating rod 412, and the first gear 54 and the second gear 55 are meshed and driven.

[0046] The inner walls of the inclined section 532 respectively form a first pushing surface 536 and a second pushing surface 537. When the eccentric rod 51 slides from the fourth position point 534 towards the fifth position point 535, the first pushing surface 536 pushes the eccentric rod 51 and forces the second rotating rod 412 to rotate. When the eccentric rod 51 slides from the fifth position point 535 towards the fourth position point 534, the second pushing surface 537 pushes the eccentric rod 51 and forces the second rotating rod 412 to rotate; the rotation directions of the first pushing surface 536 and the second pushing surface 537 forcing the second rotating rod 412 to rotate are the same.

[0047] It should be noted that in this embodiment, avoidance notches 435 are provided on the outer peripheral walls of the mounting ring 43, the rotating ring 44, and the bevel gear ring 48. The avoidance notches 435 are used to avoid the laser head so that the laser head can perform laser marking on the peripheral wall of the bearing flange. The outer diameter of the first gear 54 is larger than the outer diameter of the second gear 55. When the eccentric rod 51 slides from the fourth position 534 to the fifth position 535, the eccentric rod 51 (i.e., the second rotating rod 412) rotates 180°, and when the eccentric rod 51 rotates 180°, the first rotating rod 434 (i.e., the mounting ring 43) rotates 90°. The achieved effect is that when the eccentric rod 51 slides from the fourth position 534 to the fifth position 535, the mounting ring 43 can rotate 90° around the central axis of the first rotating rod 434, so that the avoidance notch 435 rotates upward (i.e., the central axis of the bearing is parallel to the surface of the conveyor belt 2), thereby enabling the laser head to perform laser marking on the outer peripheral wall of the flange of the bearing.

[0048] The implementation principle of Embodiment 2 of the present application is as follows: After the bearing is conveyed to the marking station 11 by the conveyor belt 2, the lifting seat 3 is forced to move downward (the eccentric rod 51 moves downward to the third position 533), so that the mounting ring 43 is sleeved on the outer periphery of the bearing. Then, the rotating ring 44 is driven to rotate, so that the guide post 45 slides from the second position 315 to the first position 314. The rotating ring 44 pushes the inner wall of the guide groove 313 through the guide post 45, thereby driving the sliding block 312 to slide toward the center of the mounting ring 43, so that the clamping seat 31 can clamp and fix the flange of the bearing. Then, the lifting seat 3 is driven to lift (the eccentric rod 51 slides back to the fourth position 534), and the bearing can be lifted off the surface of the conveyor belt 2 for laser marking, improving the operation convenience of the overall structure.

[0049] When laser marking of the outer peripheral wall of the bearing flange is required in actual demand, the lifting seat 3 is driven to continue to lift (forcing the eccentric rod 51 to slide from the fourth position 534 to the fifth position 535), and the mounting ring 43 can be driven to rotate 90°, so that the laser head can perform laser marking on the outer peripheral wall of the bearing flange.

[0050] When laser marking of different surfaces of the bearing is required by "turning over" the bearing in actual demand, the lifting seat 3 is driven to lift, forcing the eccentric rod 51 to slide from the fourth position 534 to the fifth position 535, and then the lifting seat 3 is driven to move downward, forcing the eccentric rod 51 to slide from the fifth position 535 back to the fourth position 534, and the "turning over" of the bearing in the mounting ring 43 can be realized, greatly improving the adaptability of the overall structure, so that laser marking can be performed on different positions of the bearing according to actual production requirements.

[0051] Embodiment 3: The present application embodiment discloses a laser marking assembly.

[0052] The difference between the laser marking general assembly disclosed in the embodiment of the present application and Embodiment 2 lies in that: Referring to Figure 9 , in this embodiment, a rotating groove 433 is formed in the inner wall of the mounting groove 431. The rotating groove 433 is arc-shaped, and the virtual central axis of the rotating groove 433 coincides with the central axis of the mounting ring 43. One end of the rotating groove 433 is communicated with one end of the sliding groove 432. When the guide post 45 slides from the second position 315 to the first position 314 (that is, when the sliding block 312 slides to the side of the sliding groove 432 close to the center of the mounting ring 43), the sliding block 312 slides into the rotating groove 433.

[0053] The implementation principle of Embodiment 3 of the present application is as follows: When the guide post 45 slides from the second position 315 to the first position 314 (that is, when the clamping seat 31 clamps the bearing), at this time, the sliding block 312 slides into the rotating groove 433. Continuing to drive the rotating ring 44 to rotate, the rotating ring 44 can drive the sliding block 312 to turn into the rotating groove 433, so that the rotating ring 44 can drive the clamping seat 31 to rotate by a certain angle around the central axis of the mounting ring 43, and further drive the bearing to rotate by a certain angle around the central axis of the mounting ring 43. By driving the bearing to rotate by a certain angle to cooperate with the laser head, the displacement of the laser head for laser marking can be greatly reduced (especially when laser marking the outer peripheral wall of the bearing flange), and the adaptability and operation convenience of the overall structure can be improved.

[0054] Embodiment 4: The embodiment of the present application discloses a bearing laser marking device.

[0055] A bearing laser marking device includes a marking machine table and the above-mentioned laser marking general assembly, and the workbench 1 is installed in the marking machine table.

[0056] The above are the preferred embodiments of the present application. The protection scope of the present application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
