[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0032] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "plurality" means two or more, unless otherwise specifically specified.

[0033] See Figures 1 to 8, an embodiment of the present application provides a laser marking system for a firearm sight, comprising a workbench 1, a material storage device 2, a material transfer device 3, a laser marking detection device 4, and a material grabbing device 5. The material storage device 2 is provided on one side of the workbench 1, for storing parts to be marked and parts that have been marked. The material transfer device 3 is provided on one side of the workbench 1, for containing qualified marked parts and transferring qualified marked parts. The laser marking detection device 4 is provided on the workbench 1 and has a marking station, for positioning, laser marking, and marking quality inspection of parts to be marked. The material grabbing device 5 is used to grab parts to be marked from the material storage device 2 to the marking station, grab marked parts on the marking station back to the material storage device 2, and grab marked parts in batches from the material storage device 2 to the material transfer device 3.

[0034] The technical solution provided by this application utilizes a storage device 2 to store the parts to be marked and the parts that have been marked, and then utilizes a material grabbing device 5 to grab the parts to be marked and send them to a laser marking detection device 4 for marking, and then grabs the marked parts and sends them to the storage device 2. After a certain number of marked parts are stored in the storage device 2, the material grabbing device 5 is used to transfer the marked parts in batches to the material transfer device 3. The entire storage, material transfer and marking process are all automated, which is conducive to improving work efficiency and reducing labor costs and labor intensity. In addition, the laser marking detection device 4 can locate, laser mark and detect the marking quality of the parts to be marked, without relying on manual marking quality detection and positioning, which is conducive to improving marking accuracy and quality and further reducing labor costs and labor intensity.

[0035] In some embodiments, see Figure 2 The storage device 2 includes a storage rack 21, a plurality of material trays 22, and a first drive mechanism 23. The storage rack 21 is arranged on one side of the workbench 1. The plurality of material trays 22 are stacked and fixed to the driving end of the first drive mechanism 23 along the Z-axis direction. The first drive mechanism 23 is located within the frame of the storage rack 21 and is used to drive the material trays 22 to move up and down so that the material trays 22 are located at the preset position where the material grabbing device 5 grabs the material. The storage rack 21 is formed by connecting a plurality of steel bars. For example, four steel bars are placed vertically, and two steel bars are set between two adjacent vertically placed steel bars. The two steel bars are arranged opposite to each other in the Z-axis direction to connect the two adjacent vertically placed steel bars. A space is formed between the four placed steel bars, and the material trays 22 can be stacked in this space. The first drive mechanism 23 can also be set in this space and drive the material trays 22 to move up and down in this space. The preset position is that the uppermost material tray 22 is located at the top of the material storage rack 21 , so that the material grabbing device 5 can grab the material tray 22 and the material in the material tray 22 easily.

[0036] Furthermore, the storage rack 21 is provided with a plurality of positioning pieces 211. These positioning pieces 211 are arranged along the circumference of the storage rack 21 and define a positioning opening within which the material tray 22 is positioned. When the material tray 22, driven by the first drive mechanism 23, rises to a predetermined position, the topmost material tray 22 presses against the positioning pieces 211. Correspondingly, the positioning pieces 211 press against the material tray 22, securing the material tray 22 in the predetermined position.

[0037] Furthermore, the positioning piece 211 includes a fixed plate and a positioning plate. The fixed plate is fixed to the material storage rack 21. The positioning plate is connected to the side of the fixed plate facing the material tray 22. The positioning plate is inclined from bottom to top toward the material tray 22 so that the area of ​​the positioning opening defined by the multiple positioning plates is less than or equal to the area defined by the maximum edge profile of the material tray 22. By arranging the positioning plate to be inclined toward the material tray 22, and the area of ​​the positioning opening defined by the multiple positioning plates being less than or equal to the area defined by the maximum edge profile of the material tray 22, when the material tray 22 is driven by the first drive mechanism 23 to move to a preset position, it will contact the positioning plate, thereby achieving the positioning of the material tray 22.

[0038] Furthermore, the positive projection shape of the material tray 22 from top to bottom is a rectangle, and the contour area of ​​the material tray 22 gradually decreases along the top-down direction, so that after the material tray 22 contacts the positioning plate and plays a positioning role, the material tray 22 continues to move upward, so that the positioning plate can be separated from the material tray 22, avoiding continuous squeezing of the material tray 22, and facilitating the subsequent material grasping device 5 to grasp the material tray 22.

[0039] In some embodiments, at least two position sensors 212 arranged opposite to each other are provided on the storage rack 21 for detecting whether the material tray 22 is located at a preset position.

[0040] In some embodiments, the first drive mechanism 23 is driven by a servo motor and a steel rail. Specifically, a material tray 22 or a base plate is connected to a slider in the steel rail. The steel rail acts as a guide, and the slider is driven by the servo motor to move in the Z-axis direction, thereby driving the material tray 22 to move stably in the Z-axis direction.

[0041] In some embodiments, see Figure 3The laser marking detection device 4 includes a laser marker 41, a first CCD detection component 42, a material clamping and flipping component 44, a second drive mechanism 45 and a third drive mechanism 46. The laser marker 41 and the first CCD detection component 42 are both connected to the second drive mechanism 45. The second drive mechanism 45 is used to drive the laser marker 41 and the first CCD detection component 42 to move in the Z-axis direction. The first CCD detection component 42 is located above the clamping end of the material clamping and flipping component 44. The material clamping and flipping component 44 is connected to the third drive mechanism 46. The third drive mechanism 46 is used to drive the material clamping and flipping component 44 to move in the X-axis direction.

[0042] For example, after the material holding and flipping assembly 44 obtains the workpiece to be marked from the material grabbing device 5, the material holding and flipping assembly 44 will be driven by the third drive mechanism 46 to move toward the laser irradiation area of ​​the laser marker 41, so that the workpiece to be marked held by the material holding and flipping assembly 44 can be located at the laser irradiation area, and then the workpiece to be marked is irradiated with laser to complete the marking of the workpiece to be marked. Before the laser marker 41 laser marks the workpiece to be marked, the second drive mechanism 45 can also be used to drive the laser marker 41 and the first CCD detection assembly 42 to move in the Z-axis direction to adjust the distance between the laser marker 41 and the first CCD detection assembly 42 and the workpiece to be marked. Under the drive of the second drive mechanism 45, the first CCD detection assembly 42 can be moved in the Z-axis direction to achieve focusing of the first CCD detection assembly 42 and improve detection accuracy. After the workpiece to be marked is clamped by the material clamping and flipping assembly 44, the material clamping and flipping assembly 44 is driven by the third driving mechanism 46 to clamp the workpiece to be marked and move it to directly below the laser marker 41. At this time, the first CCD detection assembly 42 will detect and locate the position of the workpiece to be marked. The third driving mechanism 46 will further fine-tune the position of the workpiece to be marked based on the detection and positioning results of the first CCD detection assembly 42. The material clamping and flipping assembly 44 will also flip and adjust based on the detection and positioning results of the first CCD detection assembly 42 to ensure that the surface of the workpiece to be marked faces the laser marker 41.

[0043] In some embodiments, the laser marking detection device 4 further includes a connecting bracket 47, which is connected to the driving end of the second driving mechanism 45 and can move in the Z-axis direction as driven by the second driving mechanism 45. The laser marker 41 and the first CCD detection assembly 42 are both mounted on the connecting bracket 47, so that the first CCD detection assembly 42 and the laser marker 41 can move synchronously with the movement of the connecting bracket 47.

[0044] It should be noted that the first CCD detection component 42 is located on one side of the laser marker 41 in the X-axis direction and close to the material clamping and flipping component 44, so that the first CCD detection component 42 and the laser marker 41 will not interfere with each other, and the detection angle of the first CCD detection component 42 is diffuse, so that although the first CCD detection component 42 is not facing the workpiece to be marked, it can still detect the position of the workpiece to be marked, and the first CCD detection component 42 can also detect part of the structure of the material clamping and flipping component 44, such as the clamping end of the material clamping and flipping component 44, and judge whether the current position of the workpiece to be marked is correct according to the shape and position of the clamping end.

[0045] In some embodiments, see Figure 4 The laser marking detection device 4 also includes a second CCD detection component 43, a fixed rail and a supporting seat. The fixed rail is provided on the workbench 1 and extends in the Z-axis direction. The supporting seat is connected to the fixed rail and can be adjusted in position along the fixed rail in the Z-axis direction. The second CCD detection component 43 is connected to the supporting seat, and the detection end of the second CCD detection component 43 faces the clamping end of the material clamping and flipping component 44. The supporting seat is connected to the track groove of the fixed rail by bolts and other connecting parts. The track groove extends in the Z-axis direction, so that by changing the position of the bolt connecting the track groove, the position of the connection between the supporting seat and the fixed rail can be changed, thereby realizing the position adjustment of the supporting seat in the Z-axis direction, and then realizing the position adjustment of the second CCD detection component 43 in the Z-axis direction to adapt to the detection of parts to be marked at different heights. But generally speaking, the position of the second CCD detection component 43 will not be easily changed after the height of the clamping end of the material clamping and flipping component 44 is determined, because the height of the material clamping and flipping component 44 in the Z-axis direction is fixed, unless the material clamping and flipping component 44 is replaced, resulting in a change in the height of the new clamping end. At this time, the second CCD detection component 43 can use the characteristic of the support seat that can be adjusted in position on the Z-axis to change its position so that the second CCD detection component 43 can achieve detection at different heights.

[0046] By utilizing the first CCD detection component 42 and the second CCD detection component 43, positioning detection of the part to be marked in the X-axis direction and the Z-axis direction is realized, and by cooperating with the material clamping and flipping component 44 to flip the part to be marked, visual detection of all sides of the part to be marked except the side facing the clamping end is realized.

[0047] In some embodiments, see Figure 3 or Figure 4The material gripping and flipping assembly 44 includes a fixed bracket 441, a first flipping mechanism 442, a second flipping mechanism, a clamping assembly 443, and a mounting bracket 444. The fixed bracket 441 is connected to the driving end of the third driving mechanism 46, enabling the fixed bracket 441 to move in the X-axis direction. The first flipping mechanism 442 is connected to one side of the fixed bracket 441 in the Y-axis direction, and the flipping end of the first flipping mechanism 442 is connected to the mounting bracket 444 to drive the mounting bracket 444 to rotate up and down within the plane defined by the X-axis and Z-axis. The second flipping mechanism is connected to the mounting bracket 444, and the flipping motion end of the second flipping mechanism is connected to the clamping assembly 443, which is used to drive the clamping assembly 443 to rotate within the plane defined by the Y-axis and the Z-axis, so that the workpiece to be marked clamped by the clamping assembly 443 can rotate within the plane defined by the Y-axis and the Z-axis, so that the side surfaces of the workpiece to be marked in the Y-axis direction and the Z-axis direction can be set relative to the laser marker 41 by flipping, and then the laser marker 41 can mark multiple sides of the workpiece to be marked.

[0048] Furthermore, the clamping assembly 443 includes a clamping cylinder and a clamping member. One end of the clamping cylinder is connected to the flipping motion end of the second flipping mechanism, and the other end is connected to the clamping member to drive the clamping member to clamp or release the material.

[0049] Furthermore, mounting bracket 444 is provided with a positioning sensor, and fixed bracket 441 is provided with a flip sensor. The flip sensor is located in the movement path of the positioning sensor along with the movement of mounting bracket 444. When first flip mechanism 442 operates, driving mounting bracket 444 to rotate, the positioning sensor also moves with mounting bracket 444. When the positioning sensor moves to the flip sensor, the flip sensor receives an electrical signal, determining that mounting bracket 444 has rotated to a predetermined position, thereby achieving the rotational positioning of mounting bracket 444.

[0050] In some embodiments, see Figure 5The material grabbing device 5 includes a material grabbing assembly 51, a fourth drive mechanism 52, and a fifth drive mechanism 53. The material grabbing assembly 51 is connected to the driving end of the fourth drive mechanism 52. The fourth drive mechanism 52 is used to drive the material grabbing assembly 51 to move in the Z-axis direction. The fourth drive mechanism 52 and the material grabbing assembly 51 are both connected to the driving end of the fifth drive mechanism 53. The fifth drive mechanism 53 is used to drive the material grabbing assembly 51 and the fourth drive mechanism 52 to move synchronously in the Y-axis direction, so that the material grabbing assembly 51 approaches or moves away from the laser marking detection device 4. When grabbing material, the fourth drive mechanism 52 is activated to drive the material grabbing assembly 51 to move in the Z-axis direction, so that the material grabbing assembly 51 approaches the material tray 22 and grabs the material in the material tray 22, that is, the object to be marked. After grabbing the object to be marked, the material grabbing assembly 51 is driven by the fourth drive mechanism 52 to move in the Z-axis direction away from the material tray 22. Then the fifth driving mechanism 53 is activated to drive the fourth driving mechanism 52 and the material grabbing assembly 51 to move synchronously in the Y-axis direction, so that the material grabbing assembly 51 is close to the clamping part used to clamp the workpiece to be marked in the laser target detection device, thereby transferring the workpiece to be marked to the clamping part for laser marking.

[0051] Further, see Figure 6 The material grabbing assembly 51 includes a first grabbing cylinder 511 and a first grabber 512 , wherein the first grabber 512 is connected to the driving end of the first grabbing cylinder 511 so that the first grabber 512 can grab and release materials.

[0052] In some embodiments, see Figure 7The material grabbing device 5 also includes a tray grabbing assembly 55, a sixth drive mechanism 56, and a seventh drive mechanism 57. The driving end of the sixth drive mechanism 56 is connected to the tray grabbing assembly 55 to drive the tray grabbing assembly 55 to move in the Z-axis direction. The seventh drive mechanism 57 is provided at the driving end of the fifth drive mechanism 53. The fourth drive mechanism 52 and the sixth drive mechanism 56 are both connected to the driving end of the seventh drive mechanism 57, so that the seventh drive mechanism 57 can drive the fourth drive mechanism 52 and the sixth drive mechanism 56 to move in the X-axis direction. The tray grabbing assembly 55 is used to grab the tray 22. It is mainly used when the tray 22 needs to be replaced after a preset number of marked parts are loaded in the tray 22. When transferring the material tray 22, the sixth drive mechanism 56 drives the material tray grabbing assembly 55 to move in the Z-axis direction, so that the material tray grabbing assembly 55 moves toward the material tray 22 and completes grabbing the material tray 22, and then moves away from the material tray 22 to raise the material tray grabbing assembly 55 to avoid interference. Then the seventh drive mechanism 57 drives the sixth drive mechanism 56 to move in the X-axis direction, and the fifth drive mechanism 53 drives the seventh drive mechanism 57 to move in the Y-axis direction, which in turn drives the material tray grabbing assembly 55 to move in the X-axis and Y-axis directions, so that the material tray grabbing assembly 55 moves to one side of the material storage device 2. Then the sixth drive mechanism 56 drives the material tray grabbing assembly 55 downward again to place the material tray 22 in the preset position.

[0053] Furthermore, a material transfer device 3 is provided at a preset position to carry the material trays 22 transferred from the material storage rack 21. After the material trays 22 are stacked to a certain height, the staff will move the material transfer device 3 to another station to unload the material trays 22, completing the batch transfer of the marked parts. The material transfer device 3 can be a small cart.

[0054] In some embodiments, see Figure 7 The tray grabbing assembly 55 includes a grabbing bracket 551 and a gripper assembly 552. The gripper assembly 552 is provided on the grabbing assembly and is used to grab and release the tray 22. The grabbing bracket 551 is connected to the driving end of the sixth driving mechanism 56 so that the grabbing bracket 551 can drive the gripper assembly 552 to move in the Z-axis direction, thereby enabling the grabbing assembly to approach the tray 22 to grab the tray 22 and move away from the storage rack 21 to avoid interference with the storage rack 21.

[0055] Furthermore, the gripper assembly 552 includes a second gripping cylinder 5521, a third gripping cylinder 5522, a first clamping piece 5523, and a second clamping piece 5524. The second gripping cylinder 5521 and the third gripping cylinder 5522 are spaced apart along the Y-axis on the gripping bracket 551. The first clamping piece 5523 is connected to the driving end of the second gripping cylinder 5521, and the second clamping piece 5524 is connected to the driving end of the third gripping cylinder 5522. Such that the distance between the first clamping piece 5523 and the second clamping piece 5524 can be changed by driving the second gripping cylinder 5521 and the third gripping cylinder 5522, thereby achieving the gripping and release of the material tray 22.

[0056] In some embodiments, see Figure 8 The material grabbing device 5 also includes a material transfer mechanism 54, which is arranged on the workbench 1. The material transfer mechanism 54 is provided with a discharge station 5441 and a pick-up station 5442. The discharge station 5441 is connected to the pick-up station 5442. The discharge station 5441 is used to temporarily place the parts to be marked that the material grabbing component 51 grabs from the storage device 2. The pick-up station 5442 is used to temporarily place the parts to be marked transferred from the discharge station 5441 and provide the laser marking detection device 4 with the parts to be marked. By providing the material transfer mechanism 54, the parts to be marked that the material grabbing component 51 grabs from the material tray 22 can be placed in the material transfer mechanism 54, and then the parts to be marked are clamped by the material clamping and flipping component 44, and then marked, making the transfer of the parts to be marked smoother. Moreover, because of the existence of the material transfer mechanism 54, the material clamping and flipping component 44 can clamp the workpiece to be marked for marking while the material grabbing component 51 can continue to grab the workpiece to be marked to the material grabbing component, thereby reducing the intermediate waiting time and improving work efficiency.

[0057] Further, see Figure 8The material transfer mechanism 54 includes a support platform assembly 541, a lifting cylinder 542, a feeding assembly 543, a workstation 544, and a pushing assembly 545. The support platform assembly 541 is arranged on the workbench 1, and the lifting cylinder 542 is arranged at the bottom of the support platform assembly 541, which is used to drive the support platform assembly 541 to rise and fall in the Z-axis direction. The workstation 544 is arranged on the support platform assembly 541, which is used to receive materials delivered from the material grabbing assembly 51. The materials include both parts to be marked and parts to be marked. The workstation 544 is provided with a discharge station 5441 and a pick-up station 5442. The discharge station 5441 is mainly used to place parts to be marked, and the pick-up station 5442 is mainly used to receive parts to be marked from the discharge station 5441 and parts to be marked grabbed from the material grabbing assembly 51. Of course, the pick-up station 5442 is also used to place parts to be marked. The unloading station 5441 is connected to the retrieving station 5442, allowing material to be transferred from the unloading station 5441 to the retrieving station 5442. The feed assembly 543 is located between the workstation 544 and the support platform assembly 541. The feed assembly 543 supports and drives the workstation 544. The feed end of the feed assembly 543 is connected to the workstation 544 and is movable in the Y-axis direction, allowing the workstation 544 to move toward the material gripping and flipping assembly 44 under the drive of the feed assembly 543. The pushing assembly 545 is arranged on the work station table 544 and the pushing end of the pushing assembly 545 can move in the X-axis direction. The unloading station 5441 and the picking station 5442 are adjacent to each other along the X-axis direction, and the unloading station 5441 is located between the picking station 5442 and the pushing end, so that when the pushing end moves toward the picking station 5442, it can move the part to be marked on the unloading station 5441 to the picking station 5442, so that the first gripper 512 of the material grabbing assembly 51 can move to the picking station 5442 to pick up the material. Moreover, because the position of the material picking station 5442 remains unchanged during material picking, that is, no matter the first gripper 512 grabs the workpiece to be marked to the material clamping and flipping assembly 44, or grabs the marked workpiece and places it on the material picking station 5442, or takes the marked workpiece away from the material picking station 5442, the gripping position of the first gripper 512 always remains unchanged, which is conducive to simplifying the gripping positioning of the first gripper 512.

[0058] In some embodiments, the support platform assembly 541 includes a first support plate 5411, a second support plate 5412, a plurality of support columns 5413, and a plurality of buffer columns 5414. The plurality of support columns 5413 are located at the bottom of the first support plate 5411. The ends of the support columns 5413, distal from the first support plate 5411, are fixed to the workbench 1, such that the first support plate 5411 is spaced apart from the surface of the workbench 1, leaving space for the lifting cylinder 542. The second support plate 5412 is positioned opposite the first support plate 5411, and a plurality of buffer columns 5414 are positioned between the first support plate 5411 and the second support plate 5412 to support the second support plate 5412. The lifting cylinder 542 is fixed to the side of the first support plate 5411 facing the workbench 1, and the telescopic end of the lifting cylinder 542 extends between the first support plate 5411 and the second support plate 5412 and is connected to the second support plate 5412, so that the lifting cylinder 542 can drive the second support plate 5412 to rise and fall in the Z-axis direction.

[0059] In some embodiments, the feeding assembly 543 is arranged on the top surface of the second support plate 5412 and includes a feeding cylinder 5431 and a feeding slider 5432. The feeding slider 5432 is sleeved on the sliding end of the feeding cylinder 5431, so that the feeding slider 5432 can move in the Y-axis direction under the drive of the feeding cylinder 5431, thereby driving the workstation 544 to move in the Y-axis direction, so that the material picking station 5442 can be moved to a position for clamping by the clamping member.

[0060] In some embodiments, the pusher assembly 545 includes a pusher cylinder 5451, a connecting plate 5452, and a push rod 5453. The pusher cylinder 5451 is disposed on the workstation 544, and the telescopic end of the pusher cylinder 5451 faces the X-axis direction, so that the telescopic end of the pusher cylinder 5451 can be extended and retracted in the X-axis direction. The connecting plate 5452 is connected to the telescopic end of the pusher cylinder 5451 and extends in the Y-axis direction toward the material clamping and flipping assembly 44, so that the connecting plate 5452 can move in the X-axis direction under the drive of the pusher cylinder 5451. The push rod 5453 is connected to the end of the connecting plate 5452 away from the pushing cylinder 5451 and extends along the X-axis direction toward the discharge station 5441, so that when the connecting plate 5452 moves in the X-axis direction, it can drive the push rod 5453 to move in the X-axis direction, thereby achieving that the telescopic end of the pushing cylinder 5451 does not occupy the area of ​​the work station 544 in the Y-axis direction, and can also apply thrust to the material located on the Y-axis side of the pushing cylinder 5451, so that the material can move in the X-axis direction, which is beneficial to shorten the length of the work station 544 in the Y-axis direction and realize material pushing and avoidance.

[0061] In some embodiments, the material transfer mechanism 54 further includes a positioning assembly 546, which is disposed on the work station 544 and located on the side of the pushing assembly 545 in the Y-axis direction away from the material clamping and flipping assembly 44. The positioning end of the positioning assembly 546 is capable of extending and retracting in the Y-axis direction, and the retractable end is located above the pushing cylinder 5451, so that the retractable end can avoid the pushing cylinder 5451 during extension and retraction to avoid interference. When the retractable end of the positioning assembly 546 extends toward the material retrieving station 5442, it can push the marking piece or the piece to be marked placed on the material retrieving station 5442 toward the material clamping and flipping assembly 44, so that the marking piece or the piece to be marked collides with a baffle on the side of the work station 544 facing the material clamping and flipping assembly 44, and the baffle and the retractable end of the positioning assembly 546 are used to clamp the marking piece or the piece to be marked, thereby completing the positioning.

[0062] Furthermore, the positioning assembly 546 includes a positioning cylinder 5461 and a positioning abutment 5462. The positioning cylinder 5461 is arranged on the work station 544 and the telescopic end of the positioning cylinder 5461 is connected to one side of the positioning abutment 5462 to drive the positioning abutment 5462 to move in the Y-axis direction, so that the positioning abutment 5462 can push the marking parts or the parts to be marked on the material picking station 5442 and cooperate with the baffle to complete the extrusion positioning.

[0063] In some embodiments, the laser marking system further includes a buzzer indicator 6, which is provided on the workbench 1 and is configured to emit an alarm sound and display an indicator light in one of three colors: red, yellow, or green, depending on the operating condition. A red light indicates a problem with the current operating condition, a yellow light serves as a warning of danger, and a green light indicates normal system operation.

[0064] To better understand the working process of the laser marking system, the following is a detailed introduction:

[0065] See Figures 1 to 8First, the staff places the parts to be marked into the tray 22. Then, the stacked trays 22 are stacked and placed in the stocker 21. The first drive mechanism 23 is used to drive the tray 22 to move in the Z-axis direction, so that the tray 22 is at a height that allows the material grabbing device 5 to grab it. Then, the fourth drive mechanism 52 is used to drive the material grabbing assembly 51 in the Z-axis direction, the fifth drive mechanism 53 drives the material grabbing assembly 51 in the Y-axis direction, and the seventh drive mechanism 57 drives the material grabbing assembly 51 in the X-axis direction, thereby achieving three-dimensional position adjustment of the material grabbing assembly 51, so that the material grabbing assembly 51 grabs the parts to be marked in the tray 22 and transfers them to the unloading station 5441. Next, the pusher assembly 545 pushes the object to be marked, causing it to move to the material removal station 5442. The positioning assembly 546 then pushes the object to be marked until it contacts the baffle of the workstation 544, completing the positioning of the object to be marked. The feeder assembly 543 then delivers the workstation 544 to the clamping end of the material clamping and flipping assembly 44. The material clamping and flipping assembly 44, driven by the third drive mechanism 46, moves along the X-axis to clamp the object to be marked. After the material clamping and flipping assembly 44 clamps the object to be marked, the lifting cylinder 542 lowers the workstation 544, freeing the object to be marked from the workstation 544 and facilitating the clamping of the object to be marked and moving it to the laser irradiation area of ​​the laser marker 41. The first CCD detection component 42 and the second CCD detection component 43 are used to detect the position of the part to be marked, and then the laser marker 41 is turned on to mark the part to be marked. If multiple sides need to be marked, the second flipping mechanism can also be used to drive the part to be marked to flip over to achieve marking on multiple sides. After the marking is completed, the marking inspection is carried out by using the first CCD detection component 42 and the second CCD detection component 43. After the inspection is qualified, the work station 544 is sent to the marking part by the feeding component 543 to receive the marked part, so that the marked part is located at the material picking station 5442, and then the material grabbing component 51 is used to grab the part to be marked in the material tray 22 to the discharge station 5441, and then the marked part is grabbed from the material picking station 5442 to the material tray 22. The pushing component 545 pushes the part to be marked to the material picking station 5442 at this time, and then the cycle is repeated until the material tray 22 is full of marking parts. The material tray grabbing component 55 is driven by the fifth drive mechanism 53, the sixth drive mechanism 56 and the seventh drive mechanism 57 to realize the three-dimensional space position adjustment, and then the gripper component 552 in the material tray grabbing component 55 is used to complete the grabbing of the material tray 22 and transport it to the trolley.
