Description

Technical Field

[0001] This invention relates to the field of laser etching apparatus, and particularly to an adaptive laser etching apparatus for electronic components. Background Technology

[0002] Laser etching is a precision machining technology that uses a high-power-density laser beam to locally remove or modify the surface of a material. Its core principle is to use a pulsed laser to form a light power density higher than the material evaporation threshold in the focal region. Through the photothermal conversion effect, the surface material is instantly vaporized. A CO2 laser focusing device drives the laser tube through a two-stage energy storage pulse power supply. Combined with an optical beam expanding system, the spot diameter is reduced to the micrometer level. Wavefront diffraction transformation technology can achieve energy distribution shaping, making the etching accuracy ±0.01mm. It is mainly used in fields such as photonic crystal manufacturing, spacecraft antenna reflector processing, and ITO glass circuit etching.

[0003] In the invention application with publication number CN116967620A, a laser etching device and etching method are disclosed. The device is equipped with a low-smoke laser etching mechanism, which can greatly reduce the smoke and dust in the working environment during etching and avoid pollution of the working environment and corrosion of the machine. In the invention patent with publication number CN114918553B, an adaptive control method for thermal deformation in the laser etching process is disclosed. The processing area of ​​the workpiece is gridded and the processing sequence is planned, which can better control the thermal deformation during the processing.

[0004] When a laser etching machine is working, the material that vaporizes instantly will form smoke and dust. This smoke and dust usually needs to be sucked out from the etching work position by a dust collection device to avoid affecting the operation of the industrial vision module. This allows the laser etching machine to perform etching work according to the preset settings. Most of the existing smoke and dust absorption structures are fixed to the laser etching head, making it difficult to adjust its posture and achieve the best smoke and dust absorption effect. Summary of the Invention

[0005] The core of this invention lies in using an industrial vision module in conjunction with an etching unit and a dust collection unit to adaptively adjust the etching process and its smoke adsorption, thus solving the problem of smoke generated during etching affecting etching quality in existing technologies. Simultaneously, a manually adjustable dust collection unit is introduced as a temporary adjustment, used only when the industrial vision module cannot input qualified image information and the dust collection unit cannot adjust automatically.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] An adaptive laser etching apparatus for electronic components includes a central control unit and a working part, with a connecting wire fixedly connected between the central control unit and the working part.

[0008] The working unit includes a main body, with a support frame fixedly connected to its lower end. A mounting groove is carved into the lower end of the main body, and a pair of X-axis electric slide rails are fixedly connected within the mounting groove. Electric sliders are slidably connected to each of the two X-axis electric slide rails. The lower ends of the two electric sliders are fixedly connected to the same Y-axis electric slide rail, which is perpendicular to both X-axis electric slide rails. An electric push rod is slidably connected to the Y-axis electric slide rail, and an electric slider is slidably connected to the Y-axis electric slide rail. An electric push rod is fixedly connected to the lower end of the electric slider, and an etching unit is fixedly connected to the lower end of the etching unit. An industrial vision module is fixedly connected to the lower end of the electric push rod near the etching unit. A fixed bracket is fixedly connected to the end of the electric push rod near the etching unit, and the fixed bracket includes a pair of... A fixing ring, secured by a connecting rod, is fitted around the outside of the first electric push rod, while the second electric push rod is inserted into the other fixing ring. The second electric push rod includes a push rod body, with a rotating groove carved at the lower end of the push rod body. An electric rotating shaft is rotatably connected to the rotating groove, and a dust collection unit is fixedly connected to the electric rotating shaft. A locking ring is fixedly connected to the upper end of the push rod body, and an insertion groove is carved on the side wall of the locking ring. A matching enrichment unit is inserted into the insertion groove, and an elastic connecting tube is fixedly connected between the enrichment unit and the first dust collection unit. By using an industrial vision module in conjunction with the etching unit and the first dust collection unit, the etching work and its fume adsorption work are adaptively adjusted, making the industrial vision module less susceptible to the effects of etching fumes and less likely to affect the normal operation of the etching unit.

[0009] Furthermore, the industrial vision module includes an image input module and a laser rangefinder. The image input module fine-tunes the working state of the etching unit, while the laser rangefinder is used to detect the position of the etching unit and electronic components, and to adjust the posture of the dust collection unit.

[0010] Furthermore, the two X-axis electric slide rails operate synchronously, and the running times of the two X-axis electric slide rails and the Y-axis electric slide rails are staggered, which increases the stability of the etching unit during operation and improves the etching accuracy.

[0011] Furthermore, the enrichment unit includes an enrichment tube, with multiple elastic capture fibers fixedly connected to the inner wall of the enrichment tube. Multiple adjacent elastic capture fibers overlap together, and an air outlet is drilled at the lower end of the enrichment tube. The three-dimensional spatial structure formed by multiple elastic capture fibers will adsorb the smoke in the air, causing the smoke to remain in the gaps between the multiple elastic capture fibers.

[0012] Furthermore, multiple partition plates are fixedly connected to the inner wall of the enrichment tube. Each partition plate has a notch, and the notches on adjacent partition plates are staggered to extend the path of the air mixed with smoke in the enrichment tube and increase the filtration effect of the enrichment unit on smoke.

[0013] Furthermore, both the enrichment tubes and the elastic capture fibers are made of transparent materials, facilitating observation by staff and enabling timely replacement of the enrichment units.

[0014] Meanwhile, a second suction unit is fitted on the outer side of the electric shaft to replace the first suction unit. A friction ring is fixedly connected to the side of the electric shaft near the second suction unit. The second suction unit contacts the friction ring, and both surfaces of the second suction unit and the friction ring are frosted. The second suction unit includes a suction part. A movable groove is cut at the end of the suction part away from the friction ring. A repulsion ring is fixedly connected to the bottom plate of the movable groove. An electromagnetic ring that matches the repulsion ring is fixedly connected to the side wall of the electric shaft. When the electromagnetic ring is energized, it repels the repulsion ring.

[0015] Furthermore, the support frame is equipped with multiple infrared detection units. When the system detects that a worker's hand has entered the support frame, the etching unit stops working, which is less likely to cause accidental injury to the worker. The central control unit is equipped with a fingerprint recognition unit. Before manually adjusting the second vacuum unit, the worker needs to perform fingerprint recognition, which makes it less likely for the second vacuum unit to be accidentally touched by unauthorized personnel.

[0016] Furthermore, the second suction unit can be manually adjusted. When it needs to return to the automatic adjustment, the second suction unit rotates to the extreme horizontal position. At this time, the second suction unit points to the etched unit, so that the second suction unit returns to the preset position, and the system error is not easily caused by the initial position of the second suction unit.

[0017] Compared with the prior art, the advantages of this invention are:

[0018] During the etching process, the industrial vision module acquires image signals from the surface of the electronic components in real time, identifies the location of marker points, calculates the deformation of the marker point area, and then determines the width of the etching line. When the width exceeds the preset value, the output power of the etching unit is reduced; conversely, the output power of the etching unit is increased until the width of the etching line meets the requirements. The industrial vision module works in conjunction with the etching unit and the first dust collection unit. The first dust collection unit approaches the electronic components as close as possible to the etching position without affecting the normal operation of the etching unit. The angle of the first dust collection unit is then adjusted to adaptively adjust the etching process and its smoke adsorption, making the industrial vision module less susceptible to the effects of etching smoke and less likely to affect the normal operation of the etching unit.

[0019] Meanwhile, a manually adjustable dust collection unit 2 is introduced as a temporary adjustment, which is only used when the industrial vision module cannot record qualified image information and the dust collection unit 2 cannot adjust automatically, thereby increasing the effective range of use of the etching device. At the same time, the introduction of the infrared detection unit and fingerprint unit can effectively increase the security of the etching device. Attached Figure Description

[0033] The technical solutions will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0034] First implementation method:

[0035] Please see Figures 1-6 An adaptive laser etching device for electronic components includes a central control unit 1 and a working part 2. A connecting wire 3 is fixedly connected between the central control unit 1 and the working part 2. The central control unit 1 is equipped with a control chip, which can control the working state of the working part 2 and provide power to the working part 2. Both control signals and electrical energy are transmitted through the connecting wire 3. In addition, the central control unit 1 is equipped with a battery, which can provide power to the working part 2 in an environment without an external power source. The central control unit 1 can also be connected to the mains power or industrial power grid to provide power to the working part 2. Those skilled in the art can reasonably design the central control unit 1 and the working part 2 according to the prior art to meet the usage requirements of this application.

[0036] The working unit 2 includes a main working body 201. A support frame 202 is fixedly connected to the lower end of the main working body 201. A mounting groove 203 is carved into the lower end of the main working body 201. A pair of X-axis electric slide rails 204 are fixedly connected in the mounting groove 203. Electric sliders 1 are slidably connected in each of the two X-axis electric slide rails 204. The lower ends of the two electric sliders 1 are fixedly connected to the same Y-axis electric slide rail 205, and the Y-axis electric slide rail 205 is perpendicular to both X-axis electric slide rails 204. Electric slider 2 is slidably connected in the Y-axis electric slide rail 205. An electric push rod 4 is fixedly connected to the lower end of the electric slider 2. An etching unit 5 is fixedly connected to the lower end of the electric push rod 4. Through the cooperation of the pair of X-axis electric slide rails 204 and Y-axis electric slide rails 205, the etching unit 5 can be moved to any position within the range of the main working body 201. At the designated location, an industrial vision module 6 is fixedly connected to the lower end of the etching unit 5. A fixed bracket 7 is fixedly connected to the end of the electric push rod 4 near the etching unit 5. The fixed bracket 7 includes a pair of fixed rings fixed by a connecting rod. One fixed ring is sleeved on the outside of the electric push rod 4, and an electric push rod 8 is inserted into the other fixed ring. The electric push rod 8 includes a push rod body 801. A rotating groove 802 is carved at the lower end of the push rod body 801. An electric rotating shaft 9 is rotatably connected to the rotating groove 802. A dust collection unit 10 is fixedly connected to the electric rotating shaft 9. A locking ring 803 is fixedly connected to the upper end of the push rod body 801. An insertion groove is carved on the side wall of the locking ring 803. An enrichment unit 11 that matches itself is inserted into the insertion groove. An elastic connecting tube 12 is fixedly connected between the enrichment unit 11 and the dust collection unit 10.

[0037] The industrial vision module 6 includes an image input module and a laser rangefinder. The image input module can input the etched graphics and text on the surface of electronic components in real time and compare them with pre-planned graphics and text to fine-tune the working state of the etching unit 5. The laser rangefinder is used to detect the position of the etching unit 5 and the electronic components, so that the electric rotating shaft 9 can adjust the posture of the dust collection unit 10. The electric rotating shaft 9 is the same shaft as the rotating joint of the industrial mechanical wall.

[0038] In this embodiment, the electronic component to be etched is placed in the support frame 202, and the graphics or text to be etched is pre-input into the central control unit 1. The graphics and text units are then processed into a grid, and the processing sequence is planned. Then, the central control unit 1 controls the X-axis electric slide rail 204 and Y-axis electric slide rail 205 in the working part 2 to move the electric push rod 4 and the etching unit 5 to the working position according to the planned processing sequence. The etching unit 5 is then started, and the electronic component is etched according to the preset etching route. During the etching process, the industrial vision module 6 collects image signals of the surface of the electronic component in real time, identifies the position of the marker point, calculates the deformation of the marker point area, and then determines the width of the etching line. When the width exceeds the preset value, the output power of the etching unit 5 is reduced, and vice versa, the output power of the etching unit 5 is increased until the width of the etching line meets the requirements. The etching unit 5 then maintains the current power and continues to work.

[0039] During the aforementioned process, the smoke generated by laser etching affects the accuracy of the image signals acquired by the industrial vision module 6, thereby affecting the working state of the etching unit 5. The laser rangefinder installed in the industrial vision module 6 can detect the position between the etching unit 5 and the electronic components, and adjust the length of the electric push rod 8 according to the detected distance, so that the dust collection unit 10 can get as close as possible to the position of the electronic components for etching without affecting the normal operation of the etching unit 5. Then, the angle of the dust collection unit 10 is adjusted so that the dust collection unit 10 is directly facing the etching position, which facilitates the absorption of smoke. When the image information recorded by the industrial vision module 6 cannot identify the position of the marker point, the working power of the dust collection unit 10 is gradually increased from the preset power until the image information recorded by the industrial vision module 6 can normally identify the position of the marker point. The power of the dust collection unit 10 is maintained to increase the smoke absorption effect and reduce the impact of smoke on the operation of the industrial vision module 6. After the dust collection unit 10 maintains the power for 5 seconds, the working power of the dust collection unit 10 is restored to the preset power within 2 seconds.

[0040] In this embodiment, the industrial vision module 6, together with the etching unit 5 and the dust collection unit 10, adaptively adjusts the etching process and its smoke adsorption process, so that the industrial vision module 6 is not easily affected by etching smoke and does not easily affect the normal operation of the etching unit 5.

[0041] The two X-axis electric slide rails 204 operate synchronously, and the running times of the two X-axis electric slide rails 204 and the Y-axis electric slide rail 205 are staggered, which increases the stability of the etching unit 5 during operation and improves the etching accuracy.

[0042] Please see Figures 6-8 The enrichment unit 11 includes an enrichment tube 1101. Multiple elastic capture fibers 1105 are fixedly connected to the inner wall of the enrichment tube 1101. Multiple adjacent elastic capture fibers 1105 overlap together. An air outlet 1104 is drilled at the lower end of the enrichment tube 1101. Air mixed with smoke is transported into the enrichment tube 1101 through the elastic connecting tube 12. The three-dimensional spatial structure formed by multiple elastic capture fibers 1105 will adsorb the smoke in the air, so that the smoke is trapped in the gaps between multiple elastic capture fibers 1105, while the air passes through the air outlet 1104 and returns to the space of the support frame 202.

[0043] Multiple partition plates 1102 are fixedly connected to the inner wall of the enrichment tube 1101. Each partition plate 1102 has a notch 1103. The notches 1103 on adjacent partition plates 1102 are staggered to extend the path of the air mixed with smoke in the enrichment tube 1101 and increase the filtration effect of the enrichment unit 11 on the smoke. The enrichment tube 1101 and the elastic capture fiber 1105 are both made of transparent material, which makes it easy for staff to observe and replace the enrichment unit 11 in a timely manner.

[0044] Second implementation method:

[0045] Please see Figure 1 and Figures 9-11 Compared to the first embodiment, a second suction unit 13 is fitted on the outer side of the electric rotating shaft 9 to replace the first suction unit 10. A friction ring 14 is fixedly connected to the side of the electric rotating shaft 9 near the second suction unit 13. The second suction unit 13 contacts the friction ring 14, and the surfaces in contact with each other are both frosted surfaces. The second suction unit 13 includes a suction part 1301. A movable groove 1302 is chiseled at the end of the suction part 1301 away from the friction ring 14. A repulsion ring 1303 is fixedly connected to the bottom plate of the movable groove 1302. An electromagnetic ring 15 that matches the repulsion ring 1303 is fixedly connected to the side wall of the electric rotating shaft 9. When the electromagnetic ring 15 is energized, it repels the repulsion ring 1303.

[0046] When etching is in normal operation, the electromagnetic ring 15 is energized. Under the action of magnetic repulsion, the second suction unit 13 will be in close contact with the friction ring 14. At the same time, under the action of friction between the two, the second suction unit 13 is not easy to rotate relative to each other, which makes it easy to keep the second suction unit 13 fixed. When the angle of the second suction unit 13 cannot be automatically adjusted to the required angle, the user can turn off the electromagnetic ring 15 through the central control unit 1 and manually adjust the angle of the second suction unit 13 to a suitable position. Then, restart the electromagnetic ring 15 to fix the posture of the second suction unit 13 to meet the usage requirements. In particular, the manual adjustment is a temporary adjustment and is only used when the industrial vision module 6 cannot record qualified image information and the second suction unit 13 cannot be automatically adjusted.

[0047] The support frame 202 is equipped with multiple infrared detection units. When a staff member's limb is detected to be inserted into the range of the support frame 202, the etching unit 5 stops working, which is less likely to cause accidental injury to the staff member. After the staff member's limb leaves the range of the support frame 202, the etching unit 5 restarts. The central control unit 1 is equipped with a fingerprint recognition unit. Before the staff member manually adjusts the vacuuming unit 2 13, they need to perform fingerprint recognition, which makes it less likely for the vacuuming unit 2 13 to be accidentally touched by unauthorized personnel. When the vacuuming unit 2 13 is manually adjusted and needs to be restored to automatic adjustment, the vacuuming unit 2 13 rotates to the extreme horizontal position. At this time, the vacuuming unit 2 13 points to the etching unit 5, so that the vacuuming unit 2 13 returns to the preset position, which is less likely to cause system errors due to the initial position of the vacuuming unit 2 13.

[0048] Compared to the first implementation, this implementation introduces a manually adjustable dust collection unit 2 13 as a temporary adjustment. It is only used when the industrial vision module 6 cannot record qualified image information and the dust collection unit 2 13 cannot be automatically adjusted, thereby increasing the effective range of use of the etching device. At the same time, the introduction of the infrared detection unit and the fingerprint recognition unit can effectively increase the security of the etching device.

[0049] The above description is merely a preferred embodiment of the present invention; it encompasses all the protection scope of the present invention. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solutions and improved concepts of the present invention, should be covered within the protection scope of the present invention.
