In actual operation, due to the diversity of workpiece shapes and sizes, the equipment often needs to accurately identify and locate the workpiece. In addition, the exhaust gas generated during the laser marking process not only pollutes the environment, but also threatens the health of operators. Therefore, it is necessary to treat the exhaust gas and smoke to prevent the exhaust gas and smoke from spreading outside the equipment. Summary of the invention

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a laser marking device with identification and positioning functions, comprising a laser marking system, a laser marking head and an exhaust mechanism, the laser marking head is connected to the laser marking system, and also comprises a machine body, a machine cover and a marking mechanism, the machine cover is rotatably mounted on the machine body, lateral movement modules are symmetrically arranged on opposite end surfaces inside the machine body, a base is mounted on the slider of the lateral movement module, a clamping mechanism is mounted on the two bases in cooperation with each other, the marking mechanism is mounted on the two bases, the marking mechanism is located in the middle of the clamping mechanism, and a storage component is mounted between the two lateral movement modules inside the machine body;

[0005] The laser marking head is installed on the marking mechanism. The marking mechanism adjusts the relative position between the laser marking head and the workpiece, and the laser marking head marks the workpiece.

[0006] The marking mechanism includes a bracket and an axle seat mounted on the base, a vertical screw is rotatably mounted between the bracket and the axle seat, a reducer connected to the vertical screw is mounted on the bracket, the input end of the reducer is connected to the servo motor, a sliding block is mounted on the vertical screw, a carrier plate is mounted on the two sliding blocks, a slideway is arranged in the middle of the carrier plate, support plates are symmetrically mounted at both ends of the slideway above the carrier plate, a horizontal screw is rotatably mounted on the two support plates in cooperation with each other, a base is slidably mounted in the slideway, the upper end of the base is threadedly connected to the horizontal screw, a laser marking head is mounted below the base, and one end of the horizontal screw is connected to a power motor through a coupling. The vertical screw rotates under the drive of the servo motor, and drives the carrier plate to move downward or upward through the sliding block, thereby realizing the distance adjustment between the laser marking head and the workpiece. The power motor drives the horizontal screw to rotate, and the horizontal screw drives the base to move in the slide. The slide limits the base to prevent the base from rotating with the horizontal screw. When the base moves in the slide, it drives the laser marking head to move, thereby adjusting the relative position between the laser marking head and the workpiece.

[0007] The clamping mechanism comprises an electric cylinder 1 symmetrically mounted on each base, a collar is mounted on the output end of the electric cylinder 1, a sleeve is rotatably mounted on the collar, a plurality of key slots are arranged on the inner wall of the sleeve, a "bow"-shaped tube is installed between two sleeves corresponding to each other on the two bases, and both ends of the "bow"-shaped tube are provided with flat keys adapted to the key slots, and the flat keys are located in the key slots;

[0008] A driving motor and two tension plates are installed on one of the bases, an inclined slide is provided on the tension plate, a sliding shaft is slidably installed in the inclined slide, a tension wheel is rotatably installed at one end of the sliding shaft, the two tension wheels have different thicknesses, a tension spring is installed at the other end of the sliding shaft, one end of the tension spring is arranged on the base, two driving wheels are installed on the motor shaft of the driving motor, one of the driving wheels is a planetary gear structure, the planetary gear in the driving wheel of the planetary gear structure is connected with a planetary plate, and one end of the planetary plate is installed on the tension plate;

[0009] Driven wheels are installed on the two sleeves located above the base, and the positions of the two driven wheels are staggered. One driven wheel corresponds to a driving wheel and a tension wheel. Guide rollers are installed above one end of the two tension plates close to each other through pin shafts. The driving wheel, tension wheel and driven wheel are commonly connected with a transmission belt, and the transmission belt passes over the guide rollers.

[0010] The tension spring (not shown) provides tension for the tension wheel. When the electric cylinder drives the sleeve to move up and down, the movement of the driven wheel will cause the transmission belt to move with it. Therefore, the tension wheel and the tension spring are used to adjust the tightness of the transmission belt so that the transmission belt is always meshed with the driven wheel, the driving wheel and the tension wheel. The electric cylinder drives the "bow"-shaped tube to move up and down through the collar and the sleeve, providing a basis for the "bow"-shaped tube to clamp workpieces of different thicknesses. By selecting the planetary gear, the conveying directions of the two driving wheels are different, and then the two "bow"-shaped tubes can rotate in opposite directions through the transmission belt. When clamping the workpiece, the driving motor drives the driving wheel to rotate. Through the transmission of the transmission belt, the tension wheel and the driven wheel rotate synchronously, and then the sleeve is driven by the driven wheel to rotate. Under the cooperation of the flat key and the keyway, the sleeve drives the "bow"-shaped tube to rotate, and the two "bow"-shaped tubes cooperate with each other to clamp the workpiece through the protruding position.

[0011] The two ends of the "bow"-shaped tube are respectively inserted into two sleeves, the "bow"-shaped tube is slidably connected with the sleeves, the outer diameters of the two ends of the "bow"-shaped tube are equal to the inner diameters of the sleeves, and the length of the flat key is equal to the length of the keyway;

[0012] The sleeve located above the other base is provided with an electric cylinder 2, the output end of which is located in the sleeve, and is connected to one end of the "bow"-shaped tube inserted into the sleeve. When the "bow"-shaped tube clamps the workpiece and the position of the workpiece on the placement component needs to be adjusted, the electric cylinder 2 works, and the output end of the electric cylinder 2 extends or contracts, so that the "bow"-shaped tube drives the workpiece to move horizontally on the placement component.

[0013] The "bow"-shaped tube is a pipe structure with one end blocked and the other end open, a dynamic seal is arranged between the open end of the "bow"-shaped tube and the sleeve, a rotary joint is installed at one end of the sleeve connected to the opening of the "bow"-shaped tube, and the rotary joint is connected to the air extraction mechanism through a pipeline;

[0014] The protruding position of the "bow"-shaped tube is provided with a plurality of air holes. The exhaust mechanism extracts the waste gas generated during the marking process through the air holes, so that the air flows near the workpiece, and the diffusion of the waste gas is prevented in time, thereby improving the waste gas collection effect. At the same time, the workpiece can also be cooled by the flowing airflow after the marking is completed.

[0015] The protruding position of the "bow"-shaped tube is provided with a plurality of rubber sleeves with through holes and protrusions, and the protrusions and through holes are staggered. The rubber sleeves are used to prevent the "bow"-shaped tube from clamping the workpiece, and the protrusions are used to increase friction and improve the clamping effect. The through holes are adapted to the air holes.

[0016] The machine body is provided with an air intake pipe for one-way air intake, and the storage component is a mesh plate or a conveyor belt with foot supports installed at the four corners. The gas entry direction is controlled by a one-way valve so that external air can enter the laser marking equipment through the air intake pipe to supplement the air loss inside the laser marking equipment. When the laser marking equipment is not connected to the production line and is used to process a single workpiece, a mesh plate or a conveyor belt can be selected as the storage component. If the laser marking equipment is connected to the production line and used for batch marking, a conveyor belt is selected as the storage component, and the conveying equipment of the production line sends the workpiece onto the conveyor belt. After the previous workpiece is marked, the conveyor belt transports the workpiece, so that the next workpiece moves to the inside of the laser marking equipment, and the marked workpiece is moved out of the laser marking equipment.

[0017] A transparent acrylic plate is provided in the middle of the upper part of the machine cover, a through groove is provided on one side of the transparent acrylic plate above the machine cover, an opening is provided at the vertical end surface of the machine cover, and a flow isolation member is installed together with the through groove and the opening. The flow isolation member is used to block the air inside and outside the laser marking equipment to prevent the exhaust gas inside the laser marking equipment from diffusing to the external environment.

[0018] The flow partition includes two adjusting cylinders symmetrically installed on the inner side of the machine cover, and a partition connected to the adjusting cylinder through a connecting plate, one end of the partition passes through the through slot, the partition covers the opening, and a pipe is provided at the lower end of the partition to connect the air pipe of the exhaust mechanism, and a plurality of air holes are provided on the air pipe. When used to process a single workpiece, the lower end of the partition fits the workbench of the machine body. When batch processing of workpieces, the adjusting cylinder works and drives the partition to move upward, one end of the partition extends out of the through slot, and the other end of the partition no longer contacts the workbench of the machine body, and releases a part of the opening area, so that the workpiece can pass through the opening and enter the laser marking equipment. During the marking process, the exhaust mechanism extracts the exhaust gas in the laser marking equipment through the air pipe.

[0019] The flow partition includes a filling plate for blocking the through groove and a hollow plate connected to the machine cover. The hollow plate is installed above the opening, and a partition curtain is installed below the hollow plate. The partition curtain is composed of a number of flexible hollow tubes, one end of which is blocked and the other end is connected to the internal chamber of the hollow plate. A number of air holes are arranged on the side of the hollow tube facing the marking mechanism, and the hollow plate is connected to the exhaust system through a pipeline. The workpiece passes through the partition curtain and directly enters the interior of the laser marking equipment. During the marking process, when the exhaust gas diffuses to the vicinity of the partition curtain, the exhaust mechanism extracts the exhaust gas in the laser marking equipment through the partition curtain.

[0020] Compared with the prior art, the beneficial effects of the present invention are: the height and rotation angle of the "bow"-shaped tube in the vertical direction are adjusted to achieve the purpose of clamping different workpieces. A rubber sleeve is provided on the outside of the "bow"-shaped tube to prevent the "bow"-shaped tube from causing damage to the workpiece during the clamping process. A number of air holes are provided at the protruding position of the "bow"-shaped tube. During the marking process, the exhaust gas generated during the marking process is extracted through the air holes, so that the air flows near the workpiece, and the diffusion of the exhaust gas is prevented in time, thereby improving the exhaust gas collection effect. At the same time, after the marking is completed, the workpiece can also be cooled by the flowing airflow. BRIEF DESCRIPTION OF THE DRAWINGS

A slideway is arranged in the middle of the carrier plate 16, and support plates are symmetrically installed at both ends of the slideway above the carrier plate 16. A horizontal screw rod 17 is rotatably installed on the two support plates in cooperation with each other, a base is slidably installed in the slideway, and the upper end of the base is threadedly connected to the horizontal screw rod 17, a laser marking head is installed below the base, and one end of the horizontal screw rod 17 is connected to a power motor through a coupling.

[0041] The clamping mechanism includes an electric cylinder 9 symmetrically mounted on each base 6, a collar is mounted on the output end of the electric cylinder 9, a sleeve 11 is rotatably mounted on the collar, a plurality of key slots are arranged on the inner wall of the sleeve 11, a "bow"-shaped tube 7 is commonly mounted between two sleeves 11 located at positions corresponding to each other on the two bases 6, and both ends of the "bow"-shaped tube 7 are provided with flat keys adapted to the key slots, and the flat keys are located in the key slots;

[0042] A driving motor and two tension plates are installed on one of the bases 6, an inclined slide is provided on the tension plate, a sliding shaft is slidably installed in the inclined slide, a tension wheel 20 is rotatably installed at one end of the sliding shaft, the two tension wheels 20 have different thicknesses, a tension spring is installed at the other end of the sliding shaft, one end of the tension spring is arranged on the base 6, two driving wheels 19 are installed on the motor shaft of the driving motor, one of the driving wheels 19 is a planetary gear structure, the planetary gear in the driving wheel 19 of the planetary gear structure is connected to a planetary plate 23, and one end of the planetary plate 23 is installed on the tension plate;

[0043] Driven wheels 18 are installed on the two sleeves 11 located above the base 6. The positions of the two driven wheels 18 are staggered. One driven wheel 18 corresponds to a driving wheel 19 and a tension wheel 20. Guide rollers 21 are installed above one end of the two tension plates close to each other through a pin shaft. The driving wheel 19, the tension wheel 20 and the driven wheel 18 are commonly connected with a transmission belt 22, and the transmission belt 22 passes over the guide roller 21.

[0044] The tension spring provides tension for the tension wheel 20. When the electric cylinder 9 drives the sleeve 11 to move up and down, the movement of the driven wheel 18 will cause the transmission belt 22 to follow the movement. Therefore, the tension of the transmission belt 22 is regulated by the tension wheel 20 and the tension spring, so that the transmission belt 22 is always engaged with the driven wheel 18, the driving wheel 19 and the tension wheel 20 for transmission.

[0045] The electric cylinder 9 drives the "bow"-shaped tube 7 to move up and down through the ring and the sleeve 11, providing a basis for the "bow"-shaped tube 7 to clamp workpieces of different thicknesses.

[0046] By selecting the planetary gear, the conveying directions of the two driving wheels 19 are different, and then the two "bow"-shaped tubes 7 can rotate towards each other through the transmission belt 22.

[0047] The two ends of the "bow"-shaped tube 7 are respectively inserted into two sleeves 11, and the "bow"-shaped tube 7 is slidably connected with the sleeves 11. The outer diameters of the two ends of the "bow"-shaped tube 7 are equal to the inner diameters of the sleeves 11, and the length of the flat key is equal to the length of the keyway;

[0048] The second electric cylinder 10 is installed on the sleeve 11 located above the other base 6. The output end of the second electric cylinder 10 is located in the sleeve 11. The output end of the second electric cylinder 10 is connected to one end of the "bow"-shaped tube 7 inserted into the sleeve 11. When the "bow"-shaped tube 7 clamps the workpiece and the position of the workpiece on the placement component 5 needs to be adjusted, the second electric cylinder 10 works, and the output end of the second electric cylinder 10 extends or contracts, so that the "bow"-shaped tube 7 drives the workpiece to move horizontally on the placement component 5.

[0049] The “bow”-shaped tube 7 is a pipe structure with one end blocked and the other end open, a dynamic seal is arranged between the open end of the “bow”-shaped tube 7 and the sleeve 11, a rotary joint 12 is installed at one end of the sleeve 11 connected to the opening of the “bow”-shaped tube 7, and the rotary joint 12 is connected to the air extraction mechanism through a pipeline;

[0050] The protruding position of the "bow"-shaped tube 7 is provided with a plurality of air holes.

[0051] The protruding position of the "bow"-shaped tube 7 is provided with a plurality of rubber sleeves with through holes and protrusions, and the protrusions and through holes are staggered. The rubber sleeves are used to prevent the "bow"-shaped tube 7 from clamping the workpiece, and at the same time, the protrusions are used to increase friction and improve the clamping effect. The through holes are adapted to the air holes.

[0052] The working principle of the present invention is as follows: a workpiece is placed on the placement component 5, a visual sensor is installed inside the body 1, which is used to collect image data of the workpiece and transmit it to the control system. The control system analyzes the image data to obtain the position of the workpiece on the placement component 5, and then locates it in the image data to confirm the position of the laser marking head.

[0053] Under the control of the control system, the power motor drives the horizontal screw 17 to rotate, and the horizontal screw 17 drives the base to move in the slide. When the base moves in the slide, it drives the laser marking head to move, and the transverse movement module 4 drives the base 6 to move in another direction. The transverse movement module 4 and the horizontal screw 17 cooperate with each other to adjust the relative position between the laser marking head and the workpiece.

[0054] After the adjustment is completed, the workpiece is clamped again, and the driving motor drives the driving wheel 19 to rotate. Through the transmission of the transmission belt 22, the tension wheel 20 and the driven wheel 18 rotate synchronously, and then the sleeve 11 is driven by the driven wheel 18 to rotate. Under the mutual cooperation of the flat key and the keyway, the sleeve 11 drives the "bow" shaped tube 7 to rotate, and the two "bow" shaped tubes 7 cooperate with each other to clamp the workpiece through the protruding position.

[0055] After the clamping is completed, the vertical screw rod 14 rotates under the drive of the servo motor 15, and drives the carrier plate 16 to move downward or upward through the sliding block, thereby realizing the distance between the laser marking head and the workpiece. After the laser marking head moves into place, it starts to mark the workpiece.

[0056] During the marking process, the exhaust mechanism extracts the waste gas generated during the marking process through the air holes, allowing the air to flow near the workpiece, preventing the diffusion of the waste gas in time and improving the waste gas collection effect. At the same time, after the marking is completed, the workpiece can also be cooled by the flowing airflow.
