Description

Technical Field

[0001] This utility model relates to the field of polarizer processing technology, and in particular to a device for drilling and blowing chips from a perforated screen polarizer. Background Technology

[0002] A polarizer is an optical film mainly used in liquid crystal displays. Its core function is to control the brightness of the screen by selectively allowing light with a specific polarization direction to pass through. Its working principle is based on the polarization characteristics of light, allowing light with the same polarization direction to pass through while blocking light from other directions.

[0003] Drilling polarizers is typically used for structural fixation, such as fixing the polarizer to the housing or bracket with screws. It is also used to avoid components such as cameras, sensors, and buttons by leaving pre-drilled holes, or to provide space for touch chip wiring. Most drilling methods involve placing the polarizer stably, locating the position to be drilled, moving the drill bit to the positioning position via a moving component, and then using a drive component to drive the drill bit to drill the polarizer. After drilling, the dust is blown away.

[0004] However, during the drilling process, most of the polarizers are exposed without any shielding, which leads to the flying debris during drilling, making it difficult to clean. The accumulation of debris may also affect the positioning of the polarizer in subsequent processing, or even scratch the surface of the polarizer. Therefore, we urgently need a device for drilling and blowing debris from the polarizers of a perforated screen to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems of debris splashing and debris accumulation in the prior art, and to propose a debris blowing device for drilling polarizers in perforated screens.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for drilling and blowing chips from a perforated screen polarizer includes a mounting plate and a milling cutter rotatably connected to the mounting plate. It also includes: a sleeve mounted on the mounting plate, on which fans are symmetrically mounted, and on which air boxes are symmetrically mounted. An inclined baffle is fixedly mounted at the air inlet end of the air box, dividing the air box into a sedimentation chamber and a pressurization chamber that are interconnected. The sedimentation chamber is connected to the inner cavity of the sleeve. A telescopic sleeve is mounted on the sleeve, and an adsorption plate is fixedly mounted on the telescopic sleeve.

[0008] To shield debris, the width ratio of the deposition chamber to the pressurization chamber is preferably 2:1.

[0009] To reduce debris entering the fan, the angle between the inclined baffle and the horizontal plane is further defined as 30°-45°.

[0010] To collect debris, preferably, a settling trough is provided at the bottom of the sedimentation chamber, the width of which is smaller than the width of the sedimentation chamber.

[0011] In order to collect debris, preferably, the sedimentation chamber is connected to an air inlet pipe, and one end of the air inlet pipe is connected to the sleeve.

[0012] To better collect debris, the cross-sectional shape of the air inlet duct is rhomboid, with the long side of the rhomboid having an inclination angle of 45°.

[0013] In order to better attract polarizers, preferably, the adsorption plate has several holes, and the holes are equidistantly arranged around the axis of the sleeve, and a negative pressure tube is fixedly connected in the holes.

[0014] In order to drive the milling cutter to drill holes, preferably, a drive motor is fixedly mounted on the mounting plate, and the output end of the drive motor is fixedly mounted to the milling cutter.

[0015] Compared with the prior art, this utility model provides a device for drilling and blowing chips from a polarizer in a perforated screen, which has the following advantages:

[0016] 1. The polarizer drilling and chip blowing device of this perforation screen, through the cooperation of the sleeve, the adsorption plate and the negative pressure pipe, utilizes an external negative pressure machine connected to the negative pressure pipe. When the negative pressure machine is started, an adsorption effect is formed on the air intake surface of the adsorption plate. When the adsorption plate contacts and adsorbs the polarizer, the sleeve can cover the drilling position, thereby reducing the chip splashing during the drilling process.

[0017] 2. The polarizer drilling and chip removal device of this perforated screen uses a milling cutter to drill holes in the polarizer. When the chip removal groove on the milling cutter discharges the chips outward, the fan starts and draws air inward. In conjunction with the telescopic characteristics of the telescopic sleeve, when the stroke of the telescopic sleeve shortens, the distance between the chips and the air inlet pipe is reduced, which improves the collection of chips and effectively speeds up the collection of chips. The chips entering the air box will fall into the sinking trough under the obstruction of the inclined baffle, realizing the collection of chips during the drilling process and reducing the accumulation of chips.

[0018] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model reduces the flying of debris and the accumulation of debris during the drilling process. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example:

[0027] Reference Figures 1-4 A device for drilling and blowing chips from a perforated screen polarizer includes a mounting plate 1 and a milling cutter 2 rotatably connected to the mounting plate 1. A drive motor 15 is fixedly mounted on the mounting plate 1, and the output end of the drive motor 15 is fixedly mounted to the milling cutter 2.

[0028] It should be noted that mounting plate 1 needs to be installed on a machine tool or robotic arm and used in conjunction with other necessary processing equipment.

[0029] It also includes: a sleeve 3 installed on the mounting plate 1, a fan 4 symmetrically installed on the sleeve 3, a wind box 5 symmetrically installed on the sleeve 3, an inclined baffle 9 fixedly installed at the air inlet end of the wind box 5, the inclined baffle 9 dividing the wind box 5 into a sedimentation chamber and a pressurization chamber that are interconnected, the sedimentation chamber is connected to the inner cavity of the sleeve 3, and the width ratio of the sedimentation chamber and the pressurization chamber is 2:1.

[0030] The air velocity will be reduced to a certain extent at the beginning of the Z-shaped loop. In conjunction with the inclined baffle 9, it can better block debris and reduce the proportion of debris entering the fan 4.

[0031] The angle between the inclined baffle 9 and the horizontal plane is in the range of 30°-45°, preferably 45°. A sinking trough 10 is provided at the bottom of the sedimentation chamber. The width of the sinking trough 10 is smaller than the width of the sedimentation chamber. An air inlet pipe 11 is connected to the sedimentation chamber, and one end of the air inlet pipe 11 is connected to the sleeve 3. The cross-sectional shape of the air inlet pipe 11 is rhomboid, and the inclination angle of the long side of the rhomboid is in the range of 45°.

[0032] The connection end between the blower 4 and the air box 5 is the input end. When the blower 4 is started, it will draw the gas in the air box 5 carrying debris through the air inlet pipe 11. The inclined baffle 9 will block the air and the debris mixed in the air. The air will be discharged outward by the blower 4, and the impurities will fall downward into the sink trough 10. The inclined angle of the air inlet pipe 11 can better extract the internal gas.

[0033] When the milling cutter 2 drills a hole in the polarizer, the chip removal groove on the milling cutter 2 discharges the chips outwards. At the same time, the fan 4 starts and draws air inwards. With the telescopic characteristics of the telescopic sleeve 6, the internal airflow can be compressed and released, accelerating the flying of chips. The chips entering the air box 5 will fall into the sink trough 10 under the obstruction of the inclined baffle 9, thus realizing the collection of chips during the drilling process and reducing the accumulation of chips.

[0034] A telescopic sleeve 6 is installed on the sleeve 3. An adsorption plate 7 is fixedly installed on the telescopic sleeve 6. Several holes 13 are opened on the adsorption plate 7, and the holes 13 are equidistantly arranged around the axis of the sleeve 3. A negative pressure pipe 14 is fixedly connected in the several holes 13.

[0035] The telescopic sleeve 6 needs to be connected to the sleeve 3 through an external moving component to extend and retract. When the sleeve 3 moves upward, the stroke of the telescopic sleeve 6 becomes longer. When the sleeve 3 moves downward, the stroke of the telescopic sleeve 6 becomes shorter. When the stroke becomes shorter, the distance between the debris and the air inlet pipe 11 is reduced, thereby improving the collection of debris.

[0036] With the cooperation of sleeve 3, adsorption plate 7 and negative pressure pipe 14, and by connecting an external negative pressure machine to negative pressure pipe 14, when the negative pressure machine is started, an adsorption effect will be formed on the air intake surface of adsorption plate 7. When adsorption plate 7 contacts and adsorbs the polarizer, sleeve 3 can cover the drilling position, thereby reducing the flying debris during the drilling process.

[0037] In this invention, after the external negative pressure machine is connected to the negative pressure pipe 14, the adsorption plate 7 is brought into contact with the polarizer. Before contact, the milling cutter 2 and the position to be drilled on the polarizer need to be positioned. At this time, the negative pressure machine is started, and after the adsorption effect is formed on the surface of the adsorption plate 7, the adsorption plate 7 and the polarizer are adsorbed. At this time, the milling cutter 2 rotates under the drive of the drive motor 15 and drills. During the drilling process, the telescopic sleeve 6 can be moved up and down by the external mobile device. During the up and down movement, the milling cutter 2 will also move up and down. During the movement, the debris will be discharged outward. At this time, the fan 4 is started and the air in the sleeve 3 is drawn outward. The upward movement of the air will cause the debris to fly. At this time, the stroke of the telescopic sleeve 6 is shortened, reducing the distance between the air inlet pipe 11 and the debris. The debris and the air are mixed and sucked into the air box 5 through the air inlet pipe 11. The debris is blocked by the inclined baffle 9 and the separated debris falls into the sink trough 10, completing the collection of debris.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
