Description

Technical Field

[0001] The utility model relates to a laser galvanometer processing device, in particular to a laser galvanometer processing device according to the continuous movement of a disc. Background Art

[0002] A laser scanner, also called a laser galvanometer, consists of an X-Y optical scanning head, an electronic drive amplifier, and an optical reflection lens. The signal provided by the computer controller drives the optical scanning head through the drive amplifier circuit, thereby controlling the deflection of the laser beam in the X-Y plane. Simply put, a galvanometer is a kind of scanning galvanometer used in the laser industry, and its professional name is a high-speed scanning galvanometer. A galvanometer, also known as an ammeter, is designed entirely following the design method of an ammeter. The lens replaces the pointer, and the signal of the probe is replaced by a DC signal of -5V - 5V or -10V - +10V controlled by a computer to complete a predetermined action. Similar to the rotating mirror scanning system, this typical control system uses a pair of folding mirrors. The difference is that the stepping motor driving this set of lenses is replaced by a servo motor. In this control system, the use of a position sensor and the design concept of a negative feedback loop further ensure the accuracy of the system. The scanning speed and repetitive positioning accuracy of the entire system reach a new level.

[0003] Currently, during laser processing loading, workpieces are conveyed by a disc. However, the distance between workpieces placed on the disc is limited, and manual loading and unloading are required one by one. If the disc stops for a long time each time, a large amount of time is easily wasted. If the disc stops for a short time each time, it is difficult for workers to ensure that the workpieces are taken out or placed on the disc one by one in a short time. The entire process relies strongly on manual labor, has a low degree of automation, a large workload of manual operation, and low work efficiency.

[0004] Therefore, it is necessary to design a laser galvanometer processing device according to the continuous movement of a disc to solve the above technical problems. Summary of the Utility Model

[0006] A laser galvanometer processing device according to continuous disc movement, characterized in that: it includes a workbench, a laser galvanometer, a motor, a first gear, a second gear, a first rotating shaft, a second rotating shaft, a disc and a placement frame. The laser galvanometer is fixedly connected to the workbench, the motor is fixedly connected inside the workbench, the first gear is fixedly connected to the output shaft of the motor, the first rotating shaft is rotatably connected to one side of the lower part of the workbench, the second rotating shaft is rotatably connected to the other side of the lower part of the workbench, the second gears are fixedly connected to the bottoms of the first rotating shaft and the second rotating shaft, and both of the second gears are engaged with the first gear.

A plurality of the placement frames are fixedly connected in a circular array on the top of each disc, and a plurality of the offset holes are opened in a circular array on the top of each disc.

[0007] Further explanation, both the placement frame and the offset hole are evenly distributed along the circumference of the disc, and the placement frame and the offset hole are staggeredly distributed.

[0008] Further explanation, it also includes a support rod, a blanking cylinder, a baffle, an elastic member, a fixed block and a dial block. The support rods are fixedly connected to both sides of the upper part of the workbench. The blanking cylinders are fixedly sleeved in the middle of each support rod. The baffles are rotatably connected to the bottoms of the two blanking cylinders. The elastic members are connected between the two blanking cylinders and the corresponding baffles. The fixed blocks are fixedly connected to one side of the two baffles. The dial blocks are fixedly connected to the rear of each placement frame, and each dial block can abut against the corresponding fixed block.

[0009] Further explanation, the upper and lower edges of both the baffles are beveled.

[0010] Further explanation, it also includes a mounting block, an elastic plate and a calibration block. Two mounting blocks are fixedly connected to the lower part of the workbench, and the two mounting blocks are respectively located on the right sides of the first rotating shaft and the second rotating shaft.

Repeating this process can realize automatic feeding of the placing frame, thus replacing manual feeding and saving labor.

[0014] 3. Through the cooperation of the elastic plate and the calibration block, the rotation angle of the first rotating shaft and the second rotating shaft is 45 degrees each time, thereby preventing a large torque from being generated after the output shaft of the motor stops rotating, resulting in the placing frame and the laser galvanometer not being on the same vertical line, the position deviating, and the processing effect deteriorating.

Detailed Description of the Invention

[0024] The present utility model will be further described below in conjunction with specific embodiments. The illustrative embodiments and explanations of this utility model are used to explain the present utility model, but do not limit the present utility model.

[0025] Embodiment: A laser galvanometer processing device according to continuous disc movement, as Figure 1-8 shown, comprising a workbench 1, a laser galvanometer 2, a motor 3, a first gear 4, a second gear 401, a first rotating shaft 5, a second rotating shaft 6, a disc 7 and a placement frame 8. The laser galvanometer 2 is installed in the middle of the top of the workbench 1 by screws. The motor 3 is installed inside the workbench 1 by screws. The first gear 4 is welded to the output shaft of the motor 3. The first rotating shaft 5 is rotatably connected to the right side of the lower part of the workbench 1. The second rotating shaft 6 is rotatably connected to the left side of the lower part of the workbench 1. The second gears 401 are welded to the bottoms of the first rotating shaft 5 and the second rotating shaft 6. Both of the two second gears 401 are meshed with the first gear 4. The discs 7 are welded to the tops of the first rotating shaft 5 and the second rotating shaft 6, and the two discs 7 are vertically offset. Four placement frames 8 are welded in a circular array on the top of each disc 7. Four misalignment holes 9 are opened in a circular array on the top of each disc 7. The placement frames 8 and the misalignment holes 9 are evenly distributed along the circumferences of the discs 7. The placement frames 8 and the misalignment holes 9 are misaligned.

[0026] When the device needs to be used, the staff will sequentially place the workpieces into the placement frame 8, and start the laser galvanometer 2. The laser galvanometer 2 can perform laser processing on the workpieces below. Since the placement frames 8 and the misalignment holes 9 on the disk 7 are evenly distributed circumferentially, two processing states can be obtained. The first state is that the laser galvanometer 2 processes the workpiece in the placement frame 8 on the left disk 7, and the misalignment hole 9 on the right disk 7 is directly below the laser galvanometer 2. The second state is that the laser galvanometer 2 processes the workpiece in the placement frame 8 on the right disk 7, and the misalignment hole 9 on the left disk 7 is directly below the laser galvanometer 2. If the two states need to be switched with each other, just rotate the two disks 7 counterclockwise by 45 degrees at the same time. To enable the disk 7 to continuously switch between the two processing states, the staff can start the motor 3. The output shaft of the motor 3 drives the first gear 4 to rotate clockwise, then the first gear 4 can make the two second gears 401 rotate counterclockwise. The second gears 401 drive the first rotating shaft 5 and the second rotating shaft 6 to rotate counterclockwise respectively, and the two disks 7 also rotate counterclockwise at this time. When the two disks 7 rotate to 45 degrees, the operation of the motor 3 can be stopped. At this time, the output shaft of the motor 3 stops rotating, and the first gear 4, the second gear 401, the first rotating shaft 5, the second rotating shaft 6 and the disk 7 stop rotating. Then the laser galvanometer 2 can perform laser processing on the workpiece below. After processing, start the motor 3 again to switch the processing state. After each switch between the two processing states, the staff can take out the processed workpiece in the placement frame 8 and put in the workpiece to be processed, so as to realize the continuous switching between the two processing states, make the workpieces be processed alternately, and reserve more feeding and discharging time for the staff. After all the workpieces are processed, turn off the laser galvanometer 2 and the motor 3.

[0027] As Figure 1 、 Figure 4 、 Figure 5 and Figure 6 shown, it further includes a support rod 10, a blanking cylinder 11, a baffle 12, an elastic member 13, a fixing block 1301 and a dialing block 14. The support rods 10 are welded to the upper left and right sides of the workbench 1 respectively. The blanking cylinders 11 are welded and sleeved in the middle of each support rod 10. The baffles 12 are rotatably connected to the bottoms of the two blanking cylinders 11. The elastic members 13 are connected between the two blanking cylinders 11 and the corresponding baffles 12. The elastic member 13 is a torsion spring. The fixing blocks 1301 are welded to the sides of the two baffles 12 away from the blanking cylinders 11. The dialing blocks 14 are welded to the outside of each placement frame 8. The upper and lower edges of the two baffles 14 are both beveled, and each dialing block 14 can abut against the corresponding fixing block 1301.

[0028] As Figure 7 and Figure 8As shown, it further includes mounting blocks 15, elastic plates 16 and calibration blocks 17. Two of the mounting blocks 15 are mounted on the lower part of the workbench 1 by screws, and the two mounting blocks 15 are respectively located on the right side of the first rotating shaft 5 and the second rotating shaft 6. The elastic plates 16 are mounted on the left side of each mounting block 15 by screws. The calibration blocks 17 are mounted on the middle parts of the first rotating shaft 5 and the second rotating shaft 6 by screws. The structures of the two calibration blocks 17 are both octagonal, and the two elastic plates 16 are respectively clamped with the corresponding calibration blocks 17.

[0029] To save the feeding time of the staff, before using the device, the staff can stack the workpieces and put them into the blanking cylinder 11. Subsequently, when switching between the two processing states, the counterclockwise rotation of the disc 7 will drive the placement frame 8 to move circumferentially. During the movement of the placement frame 8, the dial block 14 will contact the fixed block 1301, and the dial block 14 will push the fixed block 1301 to make the baffle 12 rotate counterclockwise. At the same time, the elastic member 13 is squeezed and deformed. When the disc 7 stops rotating, at this time, the placement frame 8 is located directly below the blanking cylinder 11, and the baffle 12 is in a fully open state. The workpieces in the blanking cylinder 11 fall into the placement frame 8 without being blocked by the baffle 12. When the disc 7 rotates counterclockwise again, the dial block 14 disengages from the fixed block 1301, and the elastic member 13 resets to drive the baffle 12 to rotate clockwise to its original position. Since the upper and lower edges of the baffle 12 are beveled, the workpieces in the blanking cylinder 11 can be blocked to prevent the workpieces from falling out of the blanking cylinder 11. When the disc 7 rotates 90 degrees, the next placement frame 8 can be loaded. By repeating the above operations, the function of automatic feeding is realized. When the first rotating shaft 5 and the second rotating shaft 6 rotate counterclockwise each time, the calibration block 17 rotates counterclockwise. Each time the calibration block 17 rotates, it will squeeze the elastic plate 16 to deform outward. After the calibration block 17 stops rotating, the elastic plate 16 returns to its original state, and the inner side surface of the elastic plate 16 is close to the outer side surface of the calibration block 17. Since the structures of the calibration blocks 17 are all octagonal, the first rotating shaft 5 and the second rotating shaft 6 can be restricted to rotate only 45 degrees each time they rotate counterclockwise, so as to prevent a large torque from being generated after the output shaft of the motor 3 stops rotating, resulting in the placement frame 8 and the laser galvanometer 2 not being on the same vertical line, the position deviating, and the processing effect deteriorating.

[0030] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from the present disclosure will understand that various other embodiments can be designed without departing from the scope of the present invention. Therefore, the scope of the present invention should be limited only by the appended claims.
