Description

Technical Field

[0001] This invention relates to the field of mobile phone processing technology, and more specifically, to a hole-opening device for processing mobile phone cover plates. Background Technology

[0002] Mobile phone cover plate drilling equipment is a specialized processing equipment used to complete various precision drilling operations such as camera holes, earpiece holes, and speaker holes on materials such as mobile phone glass cover plates. Most mainstream models currently use laser processing technology, which achieves non-contact drilling through a high-energy-density laser beam. It can precisely control the size, position, and shape of the hole, and supports the processing of various hole types such as round and irregular shapes. It has the advantages of fast drilling speed, smooth hole surface without burrs, and no workpiece deformation.

[0003] Some double-layer structure processing solutions can also utilize the energy on both sides of the laser focal length to achieve simultaneous batch drilling of double glass cover plates. With the help of the air supply device, the processing melt can be discharged in time, which greatly improves the processing efficiency and yield. It is widely used in the large-scale precision production of cover glass for consumer electronics. Currently, during the drilling process of mobile phone cover plates, the powder generated will affect the accuracy of the hole opening. It is necessary to remove the glass powder while drilling in order to accurately open the hole.

[0004] In the existing technology, due to the long-term processing of mobile phone cover plates, a large amount of dust and chemical waste liquid will accumulate inside the equipment.

[0013] Furthermore, the push plate slides through the connecting plate from top to bottom, and the front and rear sides of the fixed frame are inclined. The left and right sides of the fixed frame are connected through a limiting groove. The height and width of the limiting groove can be adjusted according to actual production. The push plate passes through the limiting groove from top to bottom. A feeding slope is fixedly connected to the left side of the fixed frame. The feeding slope is located at the lower left of the limiting groove.

[0014] Furthermore, the inner and outer sides of the body are provided with a cooling assembly, which includes a second right-angle bend pipe that passes through and is fixedly connected to the left side of the fixed frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) The present invention uses the first right-angle bend to extract the dust inside the fixed cover by negative pressure and separate the dust from the airflow. The high-temperature glass micro powder generated by instantaneous vaporization and shattering will be instantly carried out by the surrounding negative pressure airflow, preventing the dust from spreading and drifting to the surroundings. At the same time, dust cleaning can be completed in the continuous processing state of the equipment, thereby reducing the accumulation of dust inside the equipment and preventing dust from adhering and contaminating the optical lens.

[0020] (2) The present invention restricts the mobile phone cover plate by setting a limiting groove, and then pushes it at a constant speed with the help of the push plate to complete the continuous feeding. Since the height and width of the limiting groove can be changed to different specifications according to actual production, it can adapt to the processing needs of mobile phone cover plates of different thicknesses and sizes. At the same time, the limiting groove restricts the collection cover plate, which can prevent the mobile phone cover plate from being misaligned during the opening process.

[0021] (3) The present invention sprays coolant in an atomized manner through the nozzle and absorbs the heat generated during the processing of the mobile phone cover. Since the entire spraying, flow and collection path of the cooling medium is completely restricted to the lower half of the processing station, it will not come into contact with the optical lens of the laser head, nor will it flow into the installation area of ​​the motion guide rail, thus avoiding the contamination of precision moving parts by the cooling waste liquid.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 8A hole-opening device for processing mobile phone cover plates includes a body 1 and a bracket 11 fixedly connected to the upper left side of the body 1. A driving component 12 is fixedly connected to the upper side inside the bracket 11. A laser cutting component 13 is fixedly connected to the telescopic end of the driving component 12. A dust collection component 2 is provided on the lower side of the driving component 12. The dust collection component 2 includes a fixed cover 21 fixedly connected to the lower side of the driving component 12.

[0034] The telescopic end of the drive component 12 slides through the upper inside of the fixed cover 21. The upper right end of the fixed cover 21 is fixedly connected to the first right-angle bend 22. The lower inside of the horizontal part of the first right-angle bend 22 is provided with a guide groove 23. The lower side of the first right-angle bend 22 is fixedly connected to a collection frame 24. The first right-angle bend 22 is connected to the collection frame 24 through the guide groove 23. The first filter screen 25 is detachably installed inside the first right-angle bend 22. The other end of the first right-angle bend 22 is connected to an external air extraction device.

[0035] Multiple first electric push rods 26 are fixedly connected to the left side of the extension of the collection frame 24. The telescopic ends of the multiple first electric push rods 26 are fixedly connected to a baffle 27. A movable groove 28 is opened on the lower side of the inside of the collection frame 24. The right side of the inside of the movable groove 28 is connected to the outside. The baffle 27 is slidably connected inside the movable groove 28. The baffle 27 is used to block the lower outlet of the collection frame 24.

[0036] The first right-angle bend 22 is partially enlarged at the horizontal part, and the collection frame 24 is fixedly connected to the lower side of the enlarged part of the first right-angle bend 22. The first filter screen 25 is located on the right side of the guide groove 23, and the left and right width of the inner cavity of the collection frame 24 is greater than the left and right width of the guide groove 23.

[0037] By adopting the above technical solution, before the laser drilling operation starts, the external air extraction device is turned on in advance to form a stable negative pressure field inside the first right-angle bend 22. This negative pressure diffuses outward through the lower opening of the fixed cover 21, forming a negative pressure air curtain in the drilling area directly below the laser head. When the drive component 12 drives the laser cutting component 13 to feed downward to complete the drilling operation, the high-temperature glass micropowder generated by instantaneous vaporization and fragmentation will be instantly engulfed by the surrounding negative pressure airflow and sucked into the first right-angle bend 22. After the dust-laden airflow enters the first right-angle bend 22, the sudden expansion of the flow cross-section due to the expanded section of the first right-angle bend 22 will cause the airflow velocity to drop sharply. The large glass particles carried in the airflow will be absorbed into the airflow. Glass dust will break free from the airflow trajectory under the influence of gravity and fall directly downwards. It will fall into the collection frame 24 below through the guide channel 23 to complete the first stage of settling. The remaining fine glass dust will continue to flow into the pipe with the airflow and will be completely intercepted by the high-precision first filter 25 set on the right side of the guide channel 23. After the equipment has been running continuously for a set period of time, the controller configured in the machine body 1 will simultaneously activate multiple first electric push rods 26 to drive the baffle 27 to slide to the left at a uniform speed along the moving channel 28, fully opening the dust discharge outlet on the lower side of the collection frame 24. The settled dust accumulated inside will automatically fall and be discharged under the influence of gravity. After the dust discharge is completed, the first electric push rods 26 will reverse and reset, and the baffle 27 will re-seal the lower outlet of the collection frame 24.

[0038] It should be noted that the cross-sectional area of ​​the expansion section is 3-5 times larger than the inlet cross-sectional area of ​​the guide channel 23, ensuring that the flow velocity is reduced to below 2m / s. This ensures that glass particles with a diameter greater than 50μm are separated from the airflow under the action of gravity. The high-temperature glass micropowder generated by instantaneous vaporization and fragmentation will be instantly carried away by the surrounding negative pressure airflow, preventing dust from spreading and drifting in all directions. At the same time, dust cleaning can be completed in the continuous processing state of the equipment, thereby reducing the accumulation of dust inside the equipment and preventing dust from adhering and contaminating the optical lens.

[0039] like Figures 1 to 6 As shown, a feeding assembly 3 is provided on the upper side of the machine body 1. The feeding assembly 3 includes electric guide rails 31 that are fixedly connected to the front and rear sides of the upper end of the machine body 1.

[0040] The electric guide rail 31 has a slider 32 inside, and the upper sides of the two sliders 32 are fixedly connected to a connecting plate 35. The upper side of the connecting plate 35 is fixedly connected to an L-shaped frame 36. The lower side of the horizontal plate of the L-shaped frame 36 is fixedly connected to a second electric push rod 37. The telescopic end of the second electric push rod 37 is fixedly connected to a push plate 38. The upper side of the machine body 1 is fixedly connected to a fixed frame 33. The right side of the fixed frame 33 is fixedly connected to a pressure sensor 39. The left side of the pressure sensor 39 is in contact with the right side of the push plate 38.

[0041] The push plate 38 slides through the connecting plate 35 from top to bottom. The front and rear sides of the fixed frame 33 are inclined. The left and right sides of the fixed frame 33 are connected to form a limiting groove 34. The height and width of the limiting groove 34 can be adjusted according to actual production. The push plate 38 passes through the limiting groove 34 from top to bottom. The left side of the fixed frame 33 is fixedly connected to the discharge slope 4, which is located at the lower left of the limiting groove 34.

[0042] By adopting the above technical solution, the second electric push rod 37 installed on the L-shaped frame 36 retracts upward and drives the push plate 38 to move upward. At this time, the phone cover can slide smoothly inside the limiting groove 34. Then, the phone cover is inserted into the fixed frame 33 through the limiting groove 34 and arranged in sequence. After the phone cover is placed, the second electric push rod 37 pushes the push plate 38 downward, so that the push plate 38 contacts the right side of the rightmost phone cover. Then, the two parallel electric guide rails 31 drive the two sliders 32 to maintain strict position synchronization, thereby driving the upper connecting plate 35 to move linearly along the guide rail direction. After the phone cover plate moves to the preset station with the connecting plate 35, the second electric push rod 37 installed on the L-shaped frame 36 extends downward, driving the push plate 38 to press down smoothly in the vertical direction, pushing the phone cover plate placed at the station to the left. The processed phone cover plate will be discharged from the left side of the limiting groove 34 and conveyed out through the feeding slope 4. When all the phone cover plates are processed, the electric guide rail 31 drives the connecting plate 35 to move to the right. If the push plate 38 presses the pressure sensor 39 inside the fixed frame 33, the controller immediately controls the second electric push rod 37 to retract upward, so that the limiting groove 34 can allow other phone cover plates to enter.

[0043] It should be noted that the pressure sensor 39 is installed in the empty area on the right side of the fixed frame 33. When the electric guide rail 31 drives the connecting plate 35 to the rightmost limit position under no-load, the push plate 38 does not contact the workpiece and triggers the sensor 39. Only then does the controller execute the retraction action. The height and width of the limiting groove 34 can be changed to different specifications according to actual production to adapt to the processing requirements of mobile phone cover plates of different thicknesses and sizes. At the same time, the limiting groove 34 restricts the mobile phone cover plate to prevent misalignment of the mobile phone cover plate during the hole-making process.

[0044] like Figure 2 and Figures 4 to 6 As shown, the inner and outer sides of the body 1 are provided with a cooling assembly 5, which includes a second right-angle bend 51 that passes through and is fixedly connected to the left side of the fixed frame 33.

[0045] A nozzle 52 is fixedly connected to the upper side of the outer surface of the second right-angle bend 51. The nozzle 52 is located below the limiting groove 34. A material collection chamber 53 is opened at the upper left end of the body 1. A second filter screen 54 is detachably installed inside the material collection chamber 53. A drain pipe 55 is fixedly connected to the left side inside the material collection chamber 53. The left end of the second right-angle bend 51 is connected to an external liquid supply device.

[0046] By adopting the above technical solution, the external cooling medium supply pump starts immediately upon completion of the laser drilling operation, delivering low-temperature coolant through the second right-angle bend 51 to the top atomizing nozzle 52. The nozzle 52 sprays the coolant upwards in the form of fine droplets, directly acting on the lower surface of the newly drilled phone cover, instantly removing the residual local high temperature from the laser processing and preventing stress cracking of the glass cover due to sudden heating and cooling. After heat exchange, the coolant will carry a small amount of fine glass fragments that fall from the drilling gap, all flowing down the surface of the body 1. The coolant enters the material collection chamber 53 located at the left end of the machine body 1. The second filter 54, which can be detachably installed inside the material collection chamber 53, completely intercepts the glass fragments mixed in with the coolant. The filtered clean coolant is discharged through the drain pipe 55 on the left side of the material collection chamber 53 and can be directly connected to the external cooling circulation system for reuse. Since the entire path of the cooling medium's spray, flow, and collection is completely restricted to the lower half of the processing station, it will not come into contact with the optical lens of the laser head or flow into the installation area of ​​the motion guide rail, thus avoiding the contamination of precision moving parts by the waste cooling liquid.

[0047] like Figure 1 , Figure 2 and Figures 4 to 6 As shown, the upper side of the body 1 is provided with a cleaning component 6, which includes a partition 61 fixedly connected inside the fixed frame 33.

[0048] The partition 61 is located below the limiting groove 34. The right end of the second right-angle bend 51 is fixedly connected to the left side of the partition 61. A scraper 63 is slidably connected to the outside of the second right-angle bend 51. A connecting rod 62 is fixedly connected to the right side of the scraper 63. The connecting rod 62 slides through the partition 61. The right end of the connecting rod 62 is pressed against the left side of the push plate 38. Two pressure springs 64 are fixedly connected between the left side of the inside of the fixed frame 33 and the left side of the scraper 63. The shape of the scraper 63 is adapted to the shape of the inner cavity of the fixed frame 33. The lower side of the scraper 63 slides against the upper side of the machine body 1.

[0049] By adopting the above technical solution, when the push plate 38 moves to the left, the push plate 38 continuously pushes the connecting rod 62, causing the connecting rod 62 to slide inside the partition 61. At the same time, the pushed connecting rod 62 will drive the scraper 63 to move, and the scraper 63 will begin to compress the pressure spring 64, causing the scraper 63 to slide uniformly to the left along the outside of the second right-angle bend 51. Because the outline of the scraper 63 is perfectly matched with the inner cavity shape of the fixed frame 33, the lower edge of the scraper 63 remains in contact with the upper surface of the machine body. During the sliding process, residual glass dust and cold water scattered on the machine body will be removed. The remaining waste liquid mixture is scraped and collected, and pushed into the collection chamber 53 on the left side to complete the cleaning of the entire surface of the machine body. When the push plate 38 returns to the right, the pressure spring 64 releases the pressure, causing the scraper 63 to move to the right until it contacts the partition plate 61, preparing for the next cleaning operation. Since the push plate 38 pushes the scraper 63 to move through the connecting rod 62 each time it moves to the left, and the scraper 63 removes the impurities and waste liquid on the upper side of the machine body 1, it avoids the long-term accumulation of dust and waste liquid that corrodes the machine body, thereby reducing the frequency and cost of daily maintenance of the equipment.

[0050] Working principle: Before operation, the external air extraction device is turned on to form a negative pressure air curtain in the opening area on the lower side of the fixed cover 21. The high-temperature glass micro powder generated by laser drilling is carried into the first right-angle bend 22 by the negative pressure airflow. After gravity settling in the expansion section, the first stage of dust collection is completed. The remaining fine dust is intercepted by the first filter 25. After the equipment has been running continuously for a set time, the first electric push rod 26 drives the baffle 27 to open the lower outlet of the collection frame 24, and the accumulated settling dust can be automatically discharged without stopping the machine, avoiding dust contamination of the optical lens. When feeding, the electric guide rail 31 drives the connecting plate 35 to move to the preset position. The second electric push rod 37 drives the push plate 38 to push the mobile phone cover plate in the fixed frame 33. The adjustable limit groove 34 is used to adapt to cover plates of different sizes. The processed cover plate is then unloaded. Slope 4 delivers the material, and pressure sensor 39 completes automatic material replenishment. This prevents misalignment during cover plate opening. The moment the laser opening is completed, the external liquid supply device atomizes and sprays the low-temperature coolant upward through the nozzle 52 at the top of the second right-angle bend 51, quickly removing the local high temperature of the cover plate and preventing stress cracking of the glass. The coolant after heat exchange, carrying fine glass fragments, flows into the collection chamber 53. After being filtered by the second filter screen 54, it is discharged from the drain pipe 55 and connected to the circulation system. As the push plate 38 pushes the cover plate to the left, it squeezes the connecting rod 62, causing the scraper 63 to slide to the left along the inner cavity of the fixed frame 33. This scrapes and collects all the dust and waste liquid mixture scattered on the machine body surface into the collection chamber 53. When the push plate 38 returns to the right, the pressure spring 64 causes the scraper 63 to automatically return to its original position, completing the cleaning of the entire machine body.
