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 uses a high-energy-density laser beam to permanently mark the surface of various materials. In bearing manufacturing, laser marking is primarily used to engrave information such as serial numbers, production dates, and brand logos to achieve product traceability, prevent counterfeiting, and improve product quality.

[0003] Conventional laser marking devices include a workbench and a laser head mounted on the workbench. The bearing to be laser-marked is secured to the workbench with the surface to be marked facing the laser head, which then marks the bearing surface. However, in practical applications, this type of laser marking device requires considerable time to secure the bearing to the workbench, and the assembly and disassembly process is cumbersome, resulting in insufficient overall efficiency for laser marking of bearings. Therefore, further improvements are 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 present application provides a laser marking assembly adopting the following technical solution:

[0006] A laser marking assembly includes 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 the workbench is slidably installed with a lifting seat, and the lifting seat is slidably installed with two clamping seats, 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.

[0007] By adopting the above-mentioned technical solution, when laser marking the surface of a bearing, the bearing is transported to the marking station via a conveyor belt. A drive assembly then forces the two clamping seats toward each other to clamp the bearing flange. The embedded arc grooves enhance the connection stability between the bearing flange and the clamping seats. 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. This reduces the possibility of the conveyor belt causing vibration during the marking process, thereby improving the quality of the laser marking. After marking is completed, the lifting seat is driven downward, forcing the two clamping seats away from each other. The marked bearing can then be discharged via the conveyor belt, significantly improving the overall efficiency of bearing marking.

[0008] Optionally, the driving assembly includes a connecting arm and a driving cylinder, two connecting arms are provided, and both connecting arms are slidably mounted on the lifting seat, the two connecting arms are correspondingly arranged with two clamping seats, each of the clamping seats is provided on the corresponding connecting arm, and 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, the driving cylinder has two piston rods, and the two piston rods of the driving cylinder are respectively connected to the two connecting arms.

[0009] By adopting the above technical solution, after the bearing is transported to the marking station, the two connecting arms are forced to move closer to each other by driving the cylinder, so that the two clamping seats can be forced to clamp the flange of the bearing together, thereby improving the convenience of disassembly and assembly between the bearing and the workbench.

[0010] Optionally, each of the connecting arms is connected to a rotating cylinder, the cylinder body of the rotating cylinder is fixed to the side wall of the connecting arm, the rotating end of the rotating cylinder is connected to the clamping seat corresponding to the connecting arm, and the clamping seat is rotatably installed on the connecting arm through the rotating cylinder.

[0011] By adopting the above-mentioned technical solution and setting up the rotating cylinder, after the two clamping seats clamp the bearing, the clamping seats can be forced to rotate by the rotating cylinder, so that the bearing can be "turned over" so that the laser head can laser mark different surfaces of the bearing according to actual needs, thereby improving the adaptability of the overall structure.

[0012] Optionally, the driving assembly includes a connecting arm, a mounting ring, a rotating ring, a guide member and a driving member, two connecting arms are provided, and both connecting arms are installed on the lifting seat; the mounting ring is arranged between the two connecting arms, and the inner peripheral wall of the mounting ring is provided with a mounting groove, and each of the clamping seats is provided with a sliding block, and the sliding block is slidably installed on the inner wall of the mounting groove; the rotating ring is rotatably connected in the mounting groove and is coaxially arranged with the mounting ring, and the guide member is provided between the rotating ring and the sliding block, and when the rotating ring rotates, the guide member forces the sliding block to displace along the radial direction of the mounting ring; the driving member is provided on the connecting arm to drive the rotating ring to rotate.

[0013] By adopting the above technical solution, after the bearing is transported to the marking station via the conveyor belt, the lifting seat is forced to move downward, so that the mounting ring is sleeved on the outer peripheral side of the bearing. Then, the driving member forces the rotating ring to rotate. Under the action of the guide member, the sliding block can slide toward the center of the mounting 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 to facilitate the laser head to laser mark the surface of the bearing.

[0014] Optionally, the guide member includes two guide posts arranged on the rotating ring, the two guide posts are arranged corresponding to the two clamping seats, and the side walls of each clamping seat are provided with a guide groove for the corresponding guide post to be embedded; the two ends of the guide groove respectively form a first point position and a second point position, and the distance from the first point position to the center of the mounting ring is greater than the distance from the second point position to the center of the mounting ring; when the rotating ring rotates and forces the guide post to slide from the second point position toward the first point position, the two clamping seats approach each other.

[0015] By adopting the above technical solution, when clamping a bearing, the rotating ring is driven to rotate, causing the guide post to slide from the second position toward the first position. The rotating ring pushes the inner wall of the guide groove through the guide post, thereby driving the clamping seat to slide toward the center of the mounting ring, so that the clamping seat can clamp and secure the bearing flange. After the bearing is marked, the rotating ring is driven to rotate in the opposite direction, causing the guide post to slide from the first position toward the second position, forcing the two clamping seats to move away from each other, loosening the bearing and improving the overall operation convenience.

[0016] Optionally, a sliding groove is provided on the inner wall of the mounting groove, and both ends of the sliding groove are extended along the radial direction of the mounting ring, and the sliding block is slidably installed in the sliding groove; a rotation groove is provided on the inner wall of the mounting groove, and the rotation groove is arc-shaped, and the virtual central axis of the rotation groove coincides with the central axis of the mounting ring; one end of the rotation groove is connected to one end of the sliding groove, and when the guide column slides from the second point position to the first point position, the sliding block slides into the rotation groove.

[0017] By adopting the above-mentioned technical solution and the arrangement of the sliding groove, as the guide post slides within the guide groove, the sliding block can slide radially along the mounting ring, thereby causing the clamping seat to clamp or release the bearing. When the guide post slides from the second position to the first position (i.e., when the clamping seat clamps the bearing), the sliding block slides into the rotating groove, continuing to drive the rotating ring to rotate. The rotating ring can drive the sliding block into the rotating groove, thereby causing the clamping seat to drive the bearing to rotate a certain angle around the central axis of the mounting ring. By rotating the bearing at a certain angle to cooperate with the laser head, the displacement of the laser head during laser marking can be significantly reduced, improving the adaptability of the overall structure.

[0018] 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 for transmission; 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.

[0019] By adopting the above technical solution, the driving motor drives the rotating shaft to rotate, and under the action of the bevel gear and the bevel gear ring, it can drive the shaft to rotate around its own central axis, thereby driving the two clamping seats to move closer to or away from each other.

[0020] Optionally, the outer peripheral wall of the mounting ring is connected to a first rotating rod, the first rotating rod is rotatably connected to the connecting arm, and the mounting ring is rotatably mounted on the connecting arm via the first rotating rod; the workbench is provided with a flip assembly for driving the first rotating rod to rotate.

[0021] By adopting the above technical solution and setting up the flip assembly, the bearing can be "turned over" so that the laser head can laser mark different surfaces of the bearing according to actual needs, thereby improving the adaptability of the overall structure.

[0022] Optionally, the connecting arm is rotatably installed with a second rotating rod, and the flip assembly includes an eccentric rod, a guide plate and a synchronous member, the eccentric rod is arranged on the outer peripheral wall of one end of the second rotating rod, and the eccentric rod and the second rotating rod are eccentrically arranged; the guide plate is arranged on the workbench, and the plate surface of the guide plate is provided with a guide groove for the eccentric rod to be embedded in; the guide groove has a straight section and an inclined section, one end of the straight section is connected to one end of the inclined section, the straight section forms a third point position away from one end of the inclined section, the straight section forms a fourth point position close to one end of the inclined section, and the inclined section forms a fifth point position away from one end of the straight section; when the eccentric rod slides from the third point position to the fourth point position, the mounting ring lifts the bearing away from the conveyor belt; when the eccentric rod slides from the fourth point position to the fifth point position, the mounting ring drives the bearing to flip and forces the central axis of the bearing to be parallel to the surface of the conveyor belt; the synchronous 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.

[0023] By adopting the above technical solution, the eccentric rod is normally located at the fourth position. When the bearing is conveyed to the marking station, the lifting seat is driven downward, allowing the mounting ring to be placed on the outer periphery of the bearing (the eccentric rod slides from the fourth position to the third position). The bearing is then clamped and secured by the clamping seat. The lifting seat is then forced upward to lift the bearing off the conveyor belt (the eccentric rod slides back to the fourth position). To laser mark the outer periphery of the bearing flange, the lifting seat is driven further upward, forcing the eccentric rod to slide from the fourth position to the fifth position. Guided by the inclined section, the eccentric rod rotates the first and second rotating rods, forcing the central axis of the bearing parallel to the surface of the conveyor belt. The outer periphery of the bearing flange can now be marked. If the bearing needs to be flipped, the lifting seat is driven downward, forcing the eccentric rod to slide from the fifth position back to the fourth position, thereby completing the flip. The effect achieved is: 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 faces the laser head for laser marking. The flipping position of the bearing can be adaptively adjusted according to actual needs, which greatly improves the flexibility of the overall structure.

[0024] In the second aspect, the present application provides a bearing laser marking device that adopts the following technical solutions:

[0025] A bearing laser marking device comprises a marking machine and the above-mentioned laser marking assembly.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By setting up two clamping seats, when laser marking the surface of the bearing, the bearing is transported to the marking station via a conveyor belt. Then, the two clamping seats are forced close to each other by the drive assembly to clamp the bearing flange. 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, reducing the possibility of the conveyor belt causing shaking of the bearing during the bearing marking process, thereby improving the quality of laser marking. After marking is completed, the lifting seat is driven to move downward and force the two clamping seats away from each other. The marked bearing can then be output outward via the conveyor belt, greatly improving the overall efficiency of bearing marking.

[0028] 2. By setting the guide column, when clamping the bearing, the rotating ring is driven to rotate, causing the guide column to slide from the second point toward the first point. The rotating ring pushes the inner wall of the guide groove through the guide column, thereby driving the clamping seat to slide toward the center of the mounting ring, so that the clamping seat can clamp and fix the bearing flange. After the bearing is marked, the rotating ring is driven to rotate in the opposite direction, causing the guide column to slide from the first point to the second point, forcing the two clamping seats to move away from each other, loosening the bearing and improving the operational convenience of the entire structure.

[0029] 3. Through the setting of the rotation groove, when the guide column slides from the second point to the first point (that is, when the clamping seat is clamped on the bearing), the sliding block slides into the rotation groove and continues to drive the rotating ring to rotate. The rotating ring can drive the sliding block to rotate into the rotation groove, so that the clamping seat can drive the bearing to rotate a certain angle around the central axis of the mounting ring. By rotating the bearing at a certain angle to cooperate with the laser head, the displacement of the laser head during laser marking can be greatly reduced, and the adaptability of the overall structure can be improved.

DETAILED DESCRIPTION

[0040] The following combination Figures 1-9 This application is described in further detail.

[0041] Example 1: The embodiment of the present application discloses a laser marking assembly.

[0042] Reference Figure 1 、 Figure 2 A laser marking assembly includes a workbench 1 and a laser head. The laser head (the laser head is conventional technology and its structure will not be elaborated on here, and it is not shown in the figure) is slidably mounted on the workbench 1, with a marking station 11 formed below the laser head. The workbench 1 is connected to a conveyor belt 2 for conveying bearings. Two positioning bars 21 are installed above the conveyor belt 2. The two positioning bars 21 are spaced apart along the width of the conveyor belt 2 and form a conveying channel 22 for the bearings to pass through.

[0043] A blocking block 23 is slidably installed on the workbench 1, and the blocking block 23 is located at the output port of the conveying channel 22 to block the bearing; in this embodiment, the blocking block 23 is driven by a cylinder, 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 conveying channel 22.

[0044] Reference Figure 1 、 Figure 3 、 Figure 4 The workbench 1 is equipped with a lifting seat 3, which is slidably mounted on the workbench 1 for lifting and lowering. The workbench 1 is equipped with a lifting cylinder 32, the cylinder body of which is fixedly mounted on the bottom of the workbench 1. 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 outward, the lifting seat 3 is lifted. The workbench 1 is provided with a lifting groove 12 for accommodating the lifting seat 3, which is directly opposite the marking station 11. The lifting seat 3 is slidably mounted with two clamping seats 31, which are respectively arranged on both sides of the marking station 11 for clamping the bearing flange. The side walls of the two clamping seats 31, which are close to each other, are provided with an embedded arc groove 311 for the bearing flange to be embedded.

[0045] It should be noted that, in this embodiment, the rear end of the marking station 11 (i.e., the side of the marking station 11 away from the conveying channel 22) also needs to be slidably provided with a blocking block 23 (this blocking block 23 is not shown in the figure), and the driving method of this blocking block 23 is also driven by a cylinder. This blocking block 23 is used to block the bearings conveyed from the conveying channel 22 to position the bearings at the marking station 11.

[0046] Reference Figure 3 、 Figure 4 The lifting seat 3 is provided with a driving assembly 4 for driving the two clamping seats 31 to move closer to or away from each other. In this embodiment, the driving assembly 4 includes a connecting arm 41 and a driving cylinder 42. Two connecting arms 41 are provided. Both connecting arms 41 are slidably mounted on the lifting seat 3. The two connecting arms 41 are correspondingly arranged with the two clamping seats 31. Each clamping seat 31 is arranged on the corresponding connecting arm 41. The clamping seat 31 is slidably mounted on the lifting seat 3 through the corresponding connecting arm 41.

[0047] The driving cylinder 42 can be a double-rod cylinder, the cylinder body of the driving cylinder 42 is fixedly connected to the lifting seat 3, and the driving cylinder 42 has two piston rods. 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 closer to or away from each other; in other embodiments, the two connecting arms 41 can be separately configured with cylinders for control.

[0048] Reference Figure 3 、 Figure 4In this embodiment, each connecting arm 41 is equipped with a rotating cylinder 411, the cylinder body of the rotating cylinder 411 is fixedly installed on the upper end side wall of the connecting arm 41, the rotating end of the rotating 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 rotating cylinder 411.

[0049] The implementation principle of Example 1 of the present application is as follows: when laser marking the surface of a bearing, the bearing is transported to the marking station 11 via the conveyor belt 2, and then the two connecting arms 41 are driven closer together so that the two clamping seats 31 can clamp the bearing flange. The arrangement 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, thereby reducing the possibility of the conveyor belt 2 causing the bearing to shake during the bearing marking process, thereby improving the quality of laser marking.

[0050] After marking is completed, the lifting seat 3 is driven downward and the two clamping seats 31 are forced away from each other. The marked bearing can then be transported outward via the conveyor belt 2, greatly improving the overall efficiency of bearing marking. The rotary cylinder 411 is set up so that after the two clamping seats 31 clamp the bearing, they can be forced to rotate by the rotating cylinder 411, thereby achieving the "flip" of the bearing, allowing the laser head to laser mark different surfaces of the bearing according to actual needs, improving the adaptability of the overall structure.

[0051] Example 2: The embodiment of the present application discloses a laser marking assembly.

[0052] The difference between the laser marking assembly disclosed in the embodiment of this application and embodiment 1 is that:

[0053] Reference Figure 5 、 Figure 6 In this embodiment, the driving assembly 4 includes a connecting arm 41, a mounting ring 43, a rotating ring 44, a guide member and a driving member. Two connecting arms 41 are provided, and the two connecting arms 41 are fixedly mounted on the lifting seat 3; the mounting ring 43 is installed between the two connecting arms 41, and the inner peripheral wall of the mounting ring 43 is provided with a mounting groove 431, and the mounting groove 431 is annular around the central axis of the mounting ring 43. One end of each clamping seat 31 extends into the mounting groove 431 and is fixedly connected to a sliding block 312. The inner wall of the mounting groove 431 is provided with a sliding groove 432, and the two ends of the sliding groove 432 extend along the radial direction of the mounting 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 mounting ring 43 through the sliding block 312, so that it can slide along the radial direction of the mounting ring 43.

[0054] Reference Figure 5、 Figure 7 The rotating ring 44 is rotatably connected to 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 guide member is arranged between the rotating ring 44 and the sliding block 312. When the rotating ring 44 rotates, the guide member forces the sliding block 312 to move along the radial direction of the mounting ring 43; in this embodiment, the guide member includes two guide columns 45, and the two guide columns 45 are fixedly mounted on the surface of the rotating ring 44 close to the clamping seat 31. The two guide columns 45 are arranged corresponding to the two clamping seats 31.

[0055] The side wall of each clamping seat 31 is provided with a guide groove 313 for the corresponding guide post 45 to be inserted into; the two ends of the guide 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 guide post 45 to slide from the second point 315 to the first point 314, the two clamping seats 31 approach each other. When the rotating ring 44 rotates in the opposite direction and forces the guide post 45 to slide from the first point 314 to the second point 315, the two clamping seats 31 move away from each other to loosen the bearing.

[0056] Reference Figure 5 、 Figure 7 The driving member is provided 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 to the surface of the rotating ring 44, and the bevel gear 47 and the bevel gear ring 48 are engaged for transmission; 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 reverse).

[0057] Reference Figure 5 、 Figure 7 、 Figure 8 The outer peripheral wall of the mounting ring 43 is fixedly connected to the first rotating rod 434, 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, and the mounting ring 43 is rotatably installed 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, and the connecting arm 41 is rotatably installed with the second rotating rod 412, the flipping assembly 5 includes an eccentric rod 51, a guide plate 52 and a synchronizer, 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 the second rotating rod 412 (that is, the eccentric rod 51 can "revolve" around the central axis of the second rotating rod 412).

[0058] The guide plate 52 is arranged vertically, and the lower end of the guide plate 52 is fixedly mounted on the surface of the workbench 1. The plate surface of the guide plate 52 is provided with a guide groove 53 for the eccentric rod 51 to be embedded. 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 connected to one end of the inclined section 532. The end of the straight section 531 away from the inclined section 532 forms a third point 533, the end of the straight section 531 close to the inclined section 532 forms a fourth point 534, and the end of the inclined section 532 away from the straight section 531 forms a fifth point 535. When the eccentric rod 51 slides from the third point 533 to the fourth point 534, the mounting ring 43 lifts the bearing away from the conveyor belt 2. When the eccentric rod 51 slides from the fourth point 534 to the fifth point 535, the mounting ring 43 drives the bearing to flip and forces the central axis of the bearing to be parallel to the surface of the conveyor belt 2.

[0059] Reference Figure 5 、 Figure 7 The synchronizer 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 synchronizer includes a first gear 54 and a second gear 55. The first gear 54 is coaxially fixed to the outer peripheral wall of the first rotating rod 434, and the second gear 55 is coaxially fixed to the outer peripheral wall of the second rotating rod 412. The first gear 54 and the second gear 55 are engaged for transmission.

[0060] The inner wall of the inclined section 532 forms a first pushing surface 536 and a second pushing surface 537 respectively. When the eccentric rod 51 slides from the fourth point position 534 to the fifth point position 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 point position 535 to the fourth point position 534, the second pushing surface 537 pushes the eccentric rod 51 and forces the second rotating rod 412 to rotate. The first pushing surface 536 and the second pushing surface 537 force the second rotating rod 412 to rotate in the same direction.

[0061] It should be noted that in this embodiment, the outer circumferential walls of the mounting ring 43, rotating ring 44, and bevel gear ring 48 are each provided with a clearance notch 435. This clearance notch 435 serves to clear the laser head, enabling the laser head to laser-mark the bearing flange. The outer diameter of the first gear 54 is larger than that 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°. When the eccentric rod 51 rotates 180°, the first rotating rod 434 (i.e., the mounting ring 43) rotates 90°. As the eccentric rod 51 slides from the fourth position 534 to the fifth position 535, the mounting ring 43 can rotate 90° about the central axis of the first rotating rod 434, allowing the clearance notch 435 to rotate upward (i.e., the central axis of the bearing is parallel to the surface of the conveyor belt 2), allowing the laser head to laser-mark the outer circumferential wall of the bearing flange.

[0062] The operating principle of Example 2 of the present application is as follows: After the bearing is transported to the marking station 11 via the conveyor belt 2, the lifting seat 3 is forced to move downward (the eccentric rod 51 moves downward to the third position 533), causing the mounting ring 43 to fit over the outer circumference of the bearing. The rotating ring 44 is then driven to rotate, causing the guide post 45 to slide from the second position 315 toward the first position 314. The rotating ring 44 pushes the inner wall of the guide groove 313 via the guide post 45, thereby driving the sliding block 312 to slide toward the center of the mounting ring 43, allowing the clamping seat 31 to clamp and secure the bearing flange. The lifting seat 3 is then driven to rise (the eccentric rod 51 slides back to the fourth position 534), thereby lifting the bearing off the surface of the conveyor belt 2 for laser marking, thereby improving the operational convenience of the overall structure.

[0063] If it is actually necessary to mark the outer peripheral wall of the bearing flange, the lifting base 3 is driven to continue to rise (forcing the eccentric rod 51 to slide from the fourth point 534 to the fifth point 535), and the mounting ring 43 can be driven to rotate 90°, so that the laser head can laser mark the outer peripheral wall of the bearing flange.

[0064] If the actual demand requires that the bearing be "turned over" to mark different surfaces of the bearing, the lifting base 3 is driven to rise, forcing the eccentric rod 51 to slide from the fourth point 534 to the fifth point 535, and then the lifting base 3 is driven to move downward, forcing the eccentric rod 51 to slide from the fifth point 535 back to the fourth point 534, so that the bearing in the mounting ring 43 can be "turned over", which greatly improves the adaptability of the overall structure, so that different positions of the bearing can be laser marked according to actual production needs.

[0065] Example 3: The embodiment of the present application discloses a laser marking assembly.

[0066] The difference between the laser marking assembly disclosed in the embodiment of this application and embodiment 2 is that:

[0067] Reference Figure 9 In this embodiment, a rotation groove 433 is opened on the inner wall of the mounting groove 431. The rotation groove 433 is arc-shaped, and the virtual central axis of the rotation groove 433 coincides with the central axis of the mounting ring 43; one end of the rotation groove 433 is connected to one end of the sliding groove 432. When the guide column 45 slides from the second point 315 to the first point 314 (that is, 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 rotation groove 433.

[0068] The implementation principle of Example 3 of the present application is as follows: when the guide post 45 slides from the second point 315 to the first point 314 (i.e., when the clamping seat 31 is clamped on the bearing), 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 rotate into the rotating groove 433, thereby enabling the rotating ring 44 to drive the clamping seat 31 to rotate a certain angle around the central axis of the mounting ring 43, and further drive the bearing to rotate a certain angle around the central axis of the mounting ring 43. By driving the bearing to rotate a certain angle to cooperate with the laser head, the displacement of the laser head during laser marking can be significantly reduced (especially when laser marking the outer peripheral wall of the bearing flange), improving the adaptability and ease of operation of the overall structure.

[0069] Example 4: This embodiment of the present application discloses a bearing laser marking device.

[0070] A bearing laser marking device includes a marking machine and the above-mentioned laser marking assembly, wherein a workbench 1 is installed in the marking machine.

[0071] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
