A laser precision drilling method and device based on CCD positioning

Abstract

This invention relates to the field of laser drilling technology, specifically disclosing a CCD-based laser precision drilling method and apparatus. The apparatus includes a housing with fixed plates mounted on both sides. A movable plate is positioned on top of the two fixed plates, and a mounting base is mounted on one outer wall of the movable plate. A laser head is mounted on the bottom of the mounting base, and protective mechanisms are mounted on both sides of the mounting base. Two clamping mechanisms and a cleaning mechanism are installed inside the housing. In this invention, the clamping mechanisms can clamp and fix both ends of the sheet metal, leaving the bottom of the sheet metal suspended. This reduces the impact of the contact area between the supporting and fixing components and the sheet metal on the working efficiency of the laser head, improving the laser drilling efficiency of the apparatus. Furthermore, the two cleaning rollers provide auxiliary support to the bottom of the sheet metal without affecting the drilling process, improving the stability of drilling large-area sheet metal and ensuring that the drilling quality is not affected.

Description

Technical Field

[0001] The present invention relates to the technical field of laser drilling, and in particular to a laser precision drilling method and device based on CCD positioning. Background Art

[0002] Laser drilling device is a device that uses laser technology to perform drilling. It uses a high-power laser beam to instantly penetrate the surface of the material, and uses a high-power density laser beam to irradiate the processed material, so that it is quickly heated to the vaporization temperature, and produces precise and stable small holes. It is suitable for drilling various materials. Laser drilling is the earliest practical laser processing technology and is also one of the main application areas of laser processing. CCD positioning is a technology that uses CCD image sensors to capture and process image information in real time to achieve target positioning. It is widely used in visual positioning systems. Laser drilling devices use CCD positioning technology to achieve high-precision and fast target positioning, and improve drilling efficiency and drilling quality.

This shape is used to reduce the contact area between the workpiece and the device. However, when the weight of the workpiece supported by the serrated bottom plate is large, scratches will appear on the contact part between the workpiece and the serrated bottom plate due to extrusion, especially for some products with high requirements on the surface of the workpiece, such as mirror steel plates, mirror steel sheets and other workpieces, which will reduce the quality of the product.

[0015] Optionally, a laser precision drilling method based on CCD positioning includes the drilling device described above, and the drilling method further includes the following steps:

[0016] Step 1: First debug the device, then open the two movable doors outward, control the two fourth sliders to move in the corresponding fourth slide grooves toward the direction close to the movable doors, and drive the first rectangular plate and the multiple components above it to move together to a position close to the movable doors;

[0017] Step 2: Then, one of the cleaning rollers is controlled to move upward to a position higher than the other cleaning roller 13, and the spacing between the two clamping mechanisms is controlled to match the width of the plate to be punched according to the width of the plate to be punched. Then, the two cleaning rollers can be controlled to rotate in opposite directions, and the plate is taken manually or with the help of a robot and placed on the top of the cleaning roller at the left end. The cleaning roller at the left end is rotated and transported to the gap between the cleaning roller at the right end and the fixed seat, and the cleaning roller at the right end is used to contact the top of the plate, so as to automatically clean up the debris attached to the top of the plate;

[0018] Step 3: After the two cleaning rollers clean the surface of the plate, the two ends of the plate entering the shell fall on the top of the two placement plates, and the two ends of the plate are pressed downward with the help of two pressing plates. Then, the two first sliders can be controlled to drive the moving plate to move to the top of the shell, and the telescopic ends of the two first electric telescopic rods are controlled to retract downward, and the mounting seat and the laser head thereunder are driven to move downward to a position close to the plate. The two rotating blocks are controlled to drive the two protective plates to rotate upward together, so that there is no obstruction under the laser head. With the help of the laser generated by the laser head, the inside of the plate can be punched;

[0019] Step 4: After the plate is processed by laser drilling, the two moving blocks are controlled to move back and forth inside the moving groove, driving the two cleaning rollers to clean the bottom of the plate, and then the telescopic ends of the two sets of third electric telescopic rods are controlled to extend upward together, driving the two placement plates and the clamped plate to move upward to the top of the shell, and the two placement plates are controlled to rotate 180 degrees together, so that the top of the plate rotates to be close to the two cleaning rollers, and as the telescopic ends of the two sets of third electric telescopic rods move downward and reset together, the plate is driven to abut against the two cleaning rollers, and the two moving cleaning rollers can be used to clean the side of the plate after rotation;

[0020] Step 5: After cleaning the surface of the punched plate, control the two pressing plates to release the pressing and clamping on both ends of the plate, and use the telescopic ends of the two first electric telescopic rods to retract downward, driving the upper movable plate and the two protective plates to move downward together, so that the two protective plates move downward to one end close to the plate, and as the two first sliders move inside the first slide groove, the two protective plates are driven to push the plate to the top of the two cleaning rollers, and the punched plate is automatically transported and discharged from the inside of the shell to the outside with the help of the two cleaning rollers.

[0021] The beneficial effects of the present invention are:

[0022] 1. In the present invention, the two ends of the plate to be punched can be clamped and fixed by setting a clamping mechanism, so that the bottom of the plate is in a suspended state, which can reduce the influence of the contact area between the supporting and fixing parts and the plate on the working efficiency of the laser head and improve the laser drilling efficiency of the device; and with the help of two cleaning rollers, the bottom of the plate can be auxiliary supported without affecting the punching of the plate, thereby improving the stability of punching large-area plates and ensuring that the punching quality is not affected.

[0023] 2. In the present invention, by setting up a cleaning mechanism, when the plate to be punched is placed inside the shell, with the help of the cooperation between two cleaning rollers and other multiple components, the debris attached to the upper and lower sides of the plate can be automatically cleaned off, thereby facilitating the subsequent punching of the plate.

[0024] 3. In the invention, during the process of laser drilling of the plate, the two protective plates are located on both sides of the laser head. The telescopic ends of the two sets of second electric telescopic rods can be controlled to drive the two protective plates to move toward the direction close to the laser head, and the external preset dust collection equipment can be controlled to start, so that suction is generated at the bottom ends of the two dust collection heads, and impurities such as smoke generated during the drilling process are automatically sucked away to avoid pollution to the surrounding working environment.

[0025] 4. In the present invention, after the plate is processed by laser drilling, a small amount of impurities will inevitably be attached to its upper and lower sides. The two moving blocks are controlled to move back and forth inside the moving groove, and the two cleaning rollers that are connected to the bottom of the plate are driven to clean the bottom of the plate. Then, the telescopic ends of the two sets of third electric telescopic rods are controlled to extend upward together, driving the clamped plate to move upward to the top of the shell together, and the two placement plates are controlled to rotate 180 degrees together, so that the top of the plate is rotated to be close to the two cleaning rollers. As the telescopic ends of the two sets of third electric telescopic rods move downward and reset together, the plate is driven to abut against the two cleaning rollers. At this time, the two moving cleaning rollers can be used to clean the side of the plate after rotation, thereby reducing the labor of subsequent staff in cleaning the plate and improving the processing efficiency of the plate.

[0047] As a technical optimization solution of the present invention, a laser precision drilling method based on CCD positioning includes the above-mentioned drilling device, and the drilling method also includes the following steps:

[0048] Step 1: First debug the device, then open the two movable doors 7 outward, control the two fourth sliders 26 to move in the corresponding fourth slide slots 11 toward the movable door 7, and drive the first rectangular plate 27 and the multiple components above it to move together to a position close to the movable door 7;

[0049] Step 2: Then, one of the cleaning rollers 13 is controlled to move upward to a position higher than the other cleaning roller 13, and according to the width of the plate to be punched, the spacing between the two clamping mechanisms is controlled to match the width of the plate to be punched, and then the two cleaning rollers 13 can be controlled to rotate in opposite directions, and the plate is taken manually or with the help of a robot and placed on the top of the cleaning roller 13 at the left end, and the cleaning roller 13 at the left end is rotated and transported to the gap position between the cleaning roller 13 at the right end and the fixed seat 31, and the cleaning roller 13 at the right end contacts the top of the plate, and the debris attached to the top of the plate is automatically cleaned off;

[0050] Step 3: After the two cleaning rollers 13 clean the surface of the plate, the two ends of the plate entering the shell 1 fall on the top of the two placement plates 12, and the two ends of the plate are pressed downward with the help of two pressing plates 23. Then, the two first sliders 14 can be controlled to drive the moving plate 4 to move to the top of the shell 1, and the telescopic ends of the two first electric telescopic rods 3 are controlled to retract downward, and the mounting seat 5 and the laser head 6 thereunder are driven to move downward to a position close to the plate. The two rotating blocks 16 are controlled to drive the two protective plates 18 to rotate upward together, so that there is no obstruction under the laser head 6. With the help of the laser generated by the laser head 6, the inside of the plate can be punched;

[0051] Step 4: After the plate is processed by laser drilling, the two moving blocks 32 are controlled to move back and forth inside the moving groove 28, driving the two cleaning rollers 13 to clean the bottom of the plate, and then the telescopic ends of the two sets of third electric telescopic rods 21 are controlled to extend upward together, driving the two placement plates 12 and the clamped plate to move upward to the top of the shell 1, and the two placement plates 12 are controlled to rotate 180 degrees together, so that the top of the plate rotates to be close to the two cleaning rollers 13, and as the telescopic ends of the two sets of third electric telescopic rods 21 move downward and reset together, the plate is driven to abut against the two cleaning rollers 13, and the two moving cleaning rollers 13 can be used to clean the side of the plate after rotation;

[0052] Step 5: After cleaning the surface of the punched plate, control the two pressing plates 23 to release the pressing and clamping on both ends of the plate, and use the telescopic ends of the two first electric telescopic rods 3 to retract downward, driving the upper movable plate 4 and the two protective plates 18 to move downward together, so that the two protective plates 18 move downward to one end close to the plate, and as the two first sliders 14 move inside the first slide groove 8, the two protective plates 18 are driven to push the plate to the top of the two cleaning rollers 13, and the punched plate is automatically transported and discharged from the inside of the shell 1 to the outside with the help of the two cleaning rollers 13.

[0053] In the present invention, when the user uses the device, the device is first debugged. Taking the microhole with a diameter of 0.02mm as an example, the specific debugging method is to use a tool to adjust the size of the laser energy beam to a horizontal cutting line width of 0.02mm and a vertical cutting line width of 0.02mm. The debugging process takes about 20 minutes. The cutting parameters are set according to the product thickness and effect. Before cutting, an embroidery needle is used to clear the nozzle to avoid multiple nozzles. The oxygen pressure of the equipment is adjusted to 1.2Mp. The focusing height of the laser head 6 is adjusted. The height cannot be too low. If it is too low, the steel sheet will move during the cutting process. If the height is too high, the cutting will be out of focus and cannot be cut through. Then the two movable doors 7 are opened outward, and the two fourth sliders 26 are controlled to move in the corresponding fourth slide groove 11 toward the direction close to the movable door 7, thereby driving the first rectangular plate 27 and multiple components above it to move to a position close to the movable door 7.

[0054] Then, if Figure 1 As shown, the telescopic end of one of the fourth electric telescopic rods 30 on the right end is controlled to move upward, driving one of the fixed seats 31 and the cleaning roller 13 to move upward together, until one of the cleaning rollers 13 moves upward to a position higher than the other cleaning roller 13, and then, according to the width of the plate to be punched, the two groups of third sliders 20 are controlled to move in the corresponding third slide grooves 10 in the approaching direction, driving the placement plates 12 of the two clamping mechanisms to move in the approaching direction together, so that the spacing between the two placement plates 12 is adapted to the width of the plate to be punched, and then the two cleaning rollers 13 can be controlled to rotate in opposite directions, that is, the cleaning roller 13 at the left end rotates clockwise. The cleaning roller 13 on the right side rotates counterclockwise, and the plate to be punched is picked up manually or with the help of a preset robot near the device and placed on the top of another cleaning roller 13 on the left side. As the bottom end of the plate contacts the surface of the cleaning roller 13 on the left side, the debris attached to the bottom end of the plate is automatically cleaned off. The plate can also be transported to the gap between the cleaning roller 13 on the right side and the fixed seat 31 with the help of the cleaning roller 13 on the left side, and the cleaning roller 13 on the right side contacts the top of the plate to automatically clean the debris attached to the top end of the plate, thereby achieving the effect of automatically cleaning the upper and lower sides of the plate, which is convenient for the subsequent plate punching work.

[0055] After the two cleaning rollers 13 clean the surface of the plate and assist the plate to move into the shell 1, the two ends of the plate entering the shell 1 fall on the top of the two placement plates 12, and the driving screws 25 arranged in the two first grooves 24 rotate, driving the two pressing plates 23 to press and fix the two ends of the plate downward, so that the bottom of the plate is in a suspended state, and then the two first sliders 14 can be controlled to drive the moving plate 4 to move to the top of the shell 1, and the telescopic ends of the two first electric telescopic rods 3 are controlled to retract downward, driving the mounting seat 5 and the laser head 6 thereunder to move downward to a position close to the plate, and controlling the two rotating blocks 16 to drive the two protective plates 18 to rotate upward together, so that there is no obstruction below the laser head 6, and the inside of the plate can be punched with the help of the laser generated by the laser head 6. Since there is no obstruction below the plate, the influence of the contact area between the supporting and fixing components and the plate on the working efficiency of the laser head 6 can be reduced, thereby improving the laser drilling efficiency of the device.

[0056] If the plate to be punched is large in area, directly clamping and fixing the two ends of the plate with the help of two clamping mechanisms will be unstable. In order to ensure that the quality of the plate punching is not adversely affected, the second rectangular plate 29 can be controlled to rotate 90 degrees after the two cleaning rollers 13 have completed the cleaning and auxiliary movement of the plate, so that the two cleaning rollers 13 and other components are rotated and adjusted together, so that the two cleaning rollers 13 are located below the plate and are parallel to the two placement plates 12. The telescopic ends of the two fourth electric telescopic rods 30 are extended upward to drive the top ends of the two cleaning rollers 13 to abut against the bottom end of the plate, so as to punch the plate. The bottom end has the effect of auxiliary support and fixation, and with the help of the rotation of the double-headed screw 34, the distance between the two rectangular blocks 35 and the two cleaning rollers 13 is adjusted, so that the distance between the two cleaning rollers 13 is adapted to the punching diameter of the plate, ensuring that the two cleaning rollers 13 are located on both sides of the punching position of the plate, without affecting the punching work, and can control the moving block 32 to adaptively move inside the moving groove 28 as the second slider 15 moves inside the second slide groove 9, so that the two cleaning rollers 13 can assist in supporting and fixing different punching positions of the plate, thereby improving the stability of punching large-area plates and ensuring that the punching quality is not affected.

[0057] In the process of laser drilling of the plate, Figure 4 As shown, at this time, the two protective plates 18 are located on both sides of the laser head 6. The telescopic ends of the two sets of second electric telescopic rods 17 can be controlled to drive the two protective plates 18 to move toward the direction close to the laser head 6, and the external preset dust collection equipment can be controlled to start, so that the bottom ends of the two dust collection heads 19 generate suction force, and the smoke and dust generated during the drilling process are automatically sucked away to avoid pollution to the surrounding working environment.

[0058] After the laser drilling of the plate is completed, the two rotating blocks 16 can be controlled to drive the two protective plates 18 to rotate downward and reset to shield the laser head 6, and then the movable plate 4 can be controlled to drive the laser head 6 to move and reset to avoid accidentally touching the switch, causing the laser head 6 to continue to emit laser downward, causing harm to the staff.

[0059] After the plate is processed by laser drilling, a small amount of impurities will inevitably be attached to its upper and lower sides. At this time, the two moving blocks 32 can be controlled to move back and forth inside the moving groove 28, and the two cleaning rollers 13 that are connected to the bottom of the plate can be driven to clean the bottom of the plate. Then, the telescopic ends of the two groups of third electric telescopic rods 21 are controlled to extend upward together, driving the two placement plates 12 and the clamped plate to move upward to the top of the shell 1, and the two placement plates 12 are controlled to rotate 180 degrees together, so that the top of the plate is rotated to be close to the two cleaning rollers 13. As the telescopic ends of the two groups of third electric telescopic rods 21 move downward and reset together, the plate is driven to abut against the two cleaning rollers 13. At this time, with the help of the two moving cleaning rollers 13, the side of the plate after rotation can be cleaned, which reduces the labor of subsequent staff in cleaning the plate and improves the processing efficiency of the plate.

[0060] After cleaning the surface of the punched plate, the two pressing plates 23 can be controlled to release the pressing and clamping of the two ends of the plate, and the multiple components of the cleaning mechanism can be controlled to move to the positions where the plate is in a state of being cleaned. Figure 1 In the state shown, the telescopic ends of the two first electric telescopic rods 3 can be retracted downward to drive the upper movable plate 4 and the two protective plates 18 to move downward together, so that after the two protective plates 18 move downward to one end close to the plate, as the two first sliders 14 move inside the first slide 8, the two protective plates 18 are driven to push the plates on the top of the two placement plates 12 to the top of the two cleaning rollers 13, and with the help of the two cleaning rollers 13 rotating counterclockwise together, the punched plates can be automatically transported and discharged from the inside of the shell 1 to the outside, thereby achieving the effect of automatic unloading, so that the efficiency of the device is effectively improved when punching multiple plates.

[0061] If it is necessary to use the device to perform drilling processing on the surface of the round tube, at this time, the double-headed screw 34 can be controlled to drive the distance between the two cleaning rollers 13 to be adjusted, so that the round tube to be punched can be placed between the two cleaning rollers 13, and with the help of the rotation of the two cleaning rollers 13, the impurities attached to the outer wall of the round tube can also be automatically cleaned, and then the first rectangular plate 27 is controlled to drive the two cleaning rollers 13 and the round tube to move to the inside of the shell 1 together. When the laser head 6 is used to perform drilling processing on the surface of the round tube, the rotation of the two cleaning rollers 13 can be used again to drive the round tube to rotate slowly and adjust the drilling position, so that when the device performs drilling processing on the round tube, there is no need to install a rotatable clamp to limit and rotate the round tube, thereby improving the applicability of the device during actual use.

[0062] Since a small amount of impurities may enter the shell 1 and the third and fourth slide grooves 10 and 11 during the use of the device, the two first sliders 14 can be controlled to move inside the corresponding first slide grooves 8, driving the movable plate 4 and the mounting seat 5 to move together to the top of the shell 1, and controlling the telescopic ends of the two first electric telescopic rods 3 to retract, driving the mounting seat 5 and the two protective plates 18 below to move downward to the inside of the shell 1, and with the help of the continued extension of the telescopic ends of the two second electric telescopic rods 17, the two dust suction heads 19 at the bottom ends of the two protective plates 18 are driven to continue to move downward until they are close to the inner bottom surface of the shell 1. At this time, as the second slider 15 is controlled to move back and forth inside the second slide groove 9, and the two first sliders 14 are synchronously controlled to move inside the first slide groove 8, the two dust suction heads 19 can be driven to comprehensively remove impurities attached to the inner bottom surface of the shell 1, the third slide groove 10 and the fourth slide groove 11, so as to facilitate the subsequent use of the device.

[0063] The first rectangular plate 27 can also be controlled to drive the two cleaning rollers 13 to move to the inside of the shell 1. With the help of the two vacuum heads 19 above the shell 1, they move downward to a position close to the cleaning rollers 13, so that impurities attached to the surfaces of the two cleaning rollers 13 can be simultaneously removed by suction, thereby facilitating the subsequent use of the two cleaning rollers 13.
