Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a cutting testing device for precision cutting of color filters. Background Technology

[0002] As a core component of optical equipment, color filters have extremely high requirements for cutting precision and edge smoothness, and must be compatible with various shapes such as rings, rectangles, and irregular shapes. However, the traditional color filter cutting equipment in the current industry has many technical defects, making it difficult to meet the needs of precision, diversification and automation. The specific pain points are that traditional color filter cutting mostly uses mechanical blade cutting or fixed angle laser cutting: mechanical blades are prone to burrs on the cutting edge due to wear, and the blade pressure is prone to cause micro deformation of the color filter, with dimensional errors of ±0.05mm or more. While fixed-angle laser cutting avoids blade wear, the laser cutting head cannot flexibly adjust the angle. When cutting beveled edges or irregular contours of color filters, it is easy to encounter cutting dead corners or edge burning. At the same time, traditional equipment relies on a single clamp or adsorption fixation, and the color filter is prone to shifting during high-speed cutting, further aggravating the accuracy deviation. This results in a yield rate of only 75%-85%, which cannot meet the precision assembly requirements of optical equipment. The positioning structure of traditional equipment is fixed. The positioning fixture designed for ring color filters is not compatible with rectangular or irregular color filters. When changing the type of processing, the positioning structure must be disassembled and the entire fixture replaced, which takes more than 30 minutes and the cost of each fixture is as high as several thousand yuan. Meanwhile, the equipment's cutting range is limited. For small or large-sized color filters, different models of equipment need to be replaced, resulting in high equipment investment costs and low production efficiency when producing multiple varieties in small batches. The traditional color filter cutting process requires multiple interventions: "manual feeding - manual positioning - cutting - manual inspection - manual sorting". Manual positioning is prone to alignment errors due to visual fatigue. Manual inspection relies on magnifying glasses or microscopes for visual inspection, which easily misses defects such as burrs and gaps, and can only inspect 60-80 filters per hour. Manual sorting is not only inefficient, but also prone to surface contamination of the filters due to hand contact. The entire process requires 2-3 operators per machine, resulting in high labor costs, and the overall operating efficiency is only 80-100 filters per hour, making it difficult to adapt to large-scale production. Traditional equipment has independent cutting and inspection devices—after cutting, filters must be manually transferred to the inspection device, which can easily cause damage during the transfer. Inspection standards are set manually, and different operators have different judgment thresholds, resulting in poor quality consistency within the same batch of products. The sorting process lacks an automated docking structure, and qualified and unqualified products must be manually sorted and stored, further extending the production cycle and easily causing material mixing problems.

[0003] In summary, the shortcomings of traditional color filter cutting equipment in terms of precision, adaptability, automation, and maintainability have become key bottlenecks restricting the high-quality development of the optical equipment industry. Therefore, developing a precision color filter cutting and testing equipment with characteristics of "high-precision cutting, multi-shape adaptation, full-process automation, and low maintenance costs" has become an urgent need to solve industry pain points and improve the efficiency and quality of color filter production.

[0022] Working Principle: This cutting and inspection equipment for precision cutting of color filters achieves high-precision cutting and quality screening of color filters through an automated process of positioning, cutting, inspection, and sorting, combined with mechanical transmission and intelligent monitoring technology. Specifically, the workflow involves replacing the shape adapter 34 on the positioning base plate 16 with the shape adapter 34 according to the shape of the color filter to be cut (ring, rectangle, or irregular shape) to ensure a perfect fit to the filter's outline. After placing the color filter on the shape adapter 34, the vacuum pump 31 at the connection between the positioning base plate 16 and the shape adapter 34 is activated. Negative pressure is generated through the air holes 33 at the bottom of the shape adapter 34, firmly adsorbing the color filter onto the positioning base plate and preventing displacement during cutting. Simultaneously, the pressure sensor inside the shape adapter 34 monitors the adsorption pressure in real time. If the pressure is lower than the set value and the adsorption is not firm, a signal is sent to the control system to pause the operation, ensuring reliable positioning. The brush plate 21 on the positioning substrate 16 is fixed to the brush plate mounting base 20 and the upper surface of the mounting cover 17. During the positioning of the filter, the brush plate can lightly wipe the dust on the surface of the filter to avoid impurities affecting the cutting accuracy. The baffle 22 plays an auxiliary limiting role for the filter, ensuring that the filter is accurately aligned with the shape adapter 34 when placed, reducing manual alignment error. The motion platform 7 on the equipment frame 8 can drive the laser mounting base 6, mounting table 10 and other components to move as a whole, realizing macroscopic adjustment of the cutting area; the laser mounting base 6 is connected to the L-shaped laser mounting bracket 1 through the laser bracket connector 2, and the laser cutting head 5 is fixed to the laser cutting head mounting base 3 through the universal metal connector 4. The universal metal connector 4 can flexibly adjust the angle of the laser cutting head 5 by ±30° to adapt to the cutting requirements of different positions of the color filter, such as edge beveling; at the same time, the cutting cooling water pipe inside the laser mounting bracket 1 works synchronously with the laser cutting head 5, continuously delivering coolant during the cutting process to prevent the laser cutting head from aging due to high temperature and ensure cutting stability. The inverted T-shaped sliding boss 13 on the mounting platform 10 cooperates with the drive motor 11 through the threaded rod 12, which can drive the support platform 26 to move laterally along the mounting platform, and transport the cutting turntable 23 to the area below the laser cutting head 5; the servo motor 27 inside the support platform 26 drives the cutting disc connecting platform 25 to rotate the cutting turntable 23, so that the color filter rotates with the turntable, and cooperates with the laser cutting head to achieve continuous cutting of ring or irregular contours; the waste chips generated during the cutting process fall into the waste chip collection groove 24 on the cutting turntable 23, and are guided through the groove to the waste chip box 35 on the side surface of the cutting turntable, so as to avoid the accumulation of waste chips affecting the cutting accuracy or contaminating the equipment; The chuck mounting seats 28 on the cutting turntable 23 are arranged in a ring array. The arc-shaped clamping heads 30 on the inner side use the elasticity of the elastic sheet 29 to assist in clamping the edge of the filter sheet. This, combined with vacuum adsorption, forms a double fixation of adsorption and clamping, further preventing the filter sheet from shifting during high-speed rotation and cutting, and ensuring the cutting dimensions. The inspection camera 18 on one side of the positioning substrate 16 is fixed to the camera mounting base 19 and has a built-in vision sensor and a ring-shaped color-changing light source. After the laser cutting is completed, the motion platform 7 moves the color filter to below the inspection camera 18. The ring-shaped color-changing light source can adjust the wavelength of the light source according to the color of the color filter. For example, a green light source is used for a red color filter to enhance the contrast between the cutting edge and the color filter body. The vision sensor captures the cutting contour image of the color filter and automatically compares it with the preset standard contour to determine whether there are defects such as burrs, gaps, and dimensional deviations at the cutting edge. The loading boxes 14 on both sides of the positioning substrate 16 are divided into qualified boxes and unqualified boxes, and are at the same height as the positioning substrate. If the detection camera determines that the filter is qualified, the motion platform moves the positioning substrate to the top of the qualified box, the vacuum pump 31 stops working, and the filter falls into the qualified box under the action of gravity. If it is determined to be unqualified, it moves to the top of the unqualified box to complete the sorting. The whole process does not require manual intervention and realizes the automatic closed loop of cutting-detection-sorting. The intelligent air pressure monitoring device 15 on one side of the motion platform 7 is connected to the air circuit installation chamber 32 to monitor the air supply pressure of the vacuum pump 31 and the air circuit sealing in real time. If the air circuit leaks and causes abnormal pressure, the device will immediately issue an alarm and stop the equipment to avoid positioning failure due to insufficient air pressure. All electrical components inside the equipment, such as drive motors, servo motors, detection cameras, and vacuum pumps, are connected by wires and coordinated by the control system to ensure that the timing of each action is accurately matched. For example, detection is started immediately after cutting and sorting is completed quickly after detection, thereby improving the overall operation efficiency. The dual fixing structure of vacuum adsorption and arc clamping, combined with the high-precision turntable rotation driven by servo motor and the laser cutting head angle adjustment, controls the cutting size error within ±0.01mm. The cutting cooling water pipe cools down in real time, avoiding high-temperature drift of the laser cutting head, further ensuring the smoothness of the cutting edge and meeting the precision assembly requirements of color filters in optical equipment. The replaceable shape adapter supports positioning of various shapes of color filters, such as rings, rectangles, and irregular shapes, and the replacement process only takes 5 minutes. The coordinated adjustment of the inverted T-shaped sliding boss and the motion platform can adapt to different sizes of color filters without changing the cutting mold, reducing the equipment investment cost for multi-variety production and adapting to the needs of small-batch, multi-batch color filter processing. From filter positioning, cutting, and waste collection to testing and sorting, the entire process is automated without human intervention. A single machine can complete the cutting and testing of 120-150 filters per hour, which is more efficient than traditional manual assistance equipment. The automatic focusing and visual comparison functions of the testing camera replace manual visual inspection, reducing the waste of qualified products or the flow of unqualified products downstream due to human error. The support feet 9 at the bottom of the equipment frame 8 enhance the overall stability of the equipment and prevent vibration from affecting the accuracy during cutting; the laser cutting head 5 is connected by a universal metal connector 4, which is flexible in adjustment and wear-resistant, and its service life is 3 times longer than that of traditional rigid connections; the combined design of the waste chip collection trough 24 and the waste chip box 35 reduces the wear of waste chips on equipment parts, and the overall failure rate of the equipment is lower than that of traditional equipment. The intelligent air pressure monitoring device 15 and pressure sensor provide real-time feedback on the equipment status. Operators only need to set the cutting parameters through the control system to complete the operation without professional skills. The quick-change design of the shape adapter 34 and the flush-height sorting structure of the loading box 14 further simplify the operation process. A single operator can manage 2-3 machines at the same time, reducing labor costs.

Drive motor 11: Fixed to one end of threaded rod 12. It provides power for the movement of inverted T-shaped sliding boss 13. By driving the threaded rod 12 to rotate, the rotational motion is converted into the horizontal linear motion of the boss, which drives the support table 26 and the cutting turntable 23 to move below the laser cutting head 5, so as to achieve precise docking of the cutting position. Threaded rod 12: Rotatably connected to the connection between the mounting platform 10 and the inverted T-shaped sliding boss 13, with one end connected to the drive motor 11.

The upper surface is fixed with a support platform 26. The T-shaped structure enhances the stability of the fit with the mounting platform 10, preventing tipping during movement. At the same time, it drives the support platform 26 and the cutting turntable 23 to move laterally along the mounting platform, realizing the position adjustment of the cutting turntable and the laser cutting head to adapt to the cutting needs of different sized color filters.

[0024] Material box 14: Movably connected to both sides of positioning base plate 16, it is divided into qualified material box and unqualified material box, and is flush with the positioning base plate. It realizes the automated sorting and storage of color filters. Qualified color filters fall into the qualified material box and unqualified color filters fall into the unqualified material box. The design of being flush with the positioning base plate ensures that the color filters slide smoothly under the action of gravity, avoiding edge damage caused by bumps when falling.

It provides mounting support for the servo motor 27 and the cutting disc connecting platform 25, and the rigid structure ensures the coaxiality of the servo motor output end and the cutting disc connecting platform, avoiding eccentricity during rotation that would cause the cutting turntable to wobble, thus ensuring cutting accuracy. Servo motor 27: Fixed inside the support platform 26, with its output end fixed to the cutting disc connecting platform 25. It provides high-precision power for the rotation of the cutting turntable 23, and its speed can be adjusted according to cutting requirements, such as uniform rotation when cutting ring-shaped color filters and variable speed rotation when cutting irregular-shaped color filters, ensuring that the rotation angle of the cutting turntable is precisely synchronized with the cutting action of the laser cutting head, so as to achieve precision cutting of complex contours. The chuck mounting base 28 is fixed to the upper surface of the cutting turntable 23 in a ring array, with an arc-shaped clamping head 30 fixed on the inner side. It provides a mounting carrier for the arc-shaped clamping head 30. The ring array distribution ensures that the edge of the filter is subjected to uniform force, avoids deformation of the filter during clamping, and adapts to the clamping requirements of different sized filters through the array spacing. Elastic sheet 29: Fixed to the end of the arc-shaped clamping head 30 away from the clamping mounting base 28. It adapts to the edge contour of the filter through elastic deformation, generating flexible pressure during clamping to avoid damage to the edge of the filter caused by rigid clamping; at the same time, it enhances the clamping friction, and together with vacuum adsorption, forms a double fixation of adsorption and clamping to prevent the filter from moving around when it is being cut at high speed. Arc-shaped clamping head 30: Fixed inside the clamping head mounting base 28, with an elastic sheet 29 fixed at the end away from the mounting base. It conforms to the curved surface of the filter edge and uses the elasticity of the elastic sheet 29 to assist in clamping the filter. In conjunction with vacuum adsorption, it further improves the stability of the filter positioning and ensures that the filter does not shift during high-speed cutting. Vacuum pump 31: Fixed inside the connection between shape adapter 34 and positioning base plate 16, and connected to the air hole 33 at the bottom of shape adapter. The negative pressure generated by the air hole 33 firmly adsorbs the color filter onto the shape adapter 34, achieving precise positioning of the color filter; it works with the arc-shaped clamping head to form a double fixation, preventing the color filter from shifting during cutting and ensuring cutting accuracy. Air path installation chamber 32: Located on the motion platform 7 corresponding to the positioning base plate 16. It houses the air path connecting the vacuum pump 31, preventing the air path from being exposed to the outside and damaged by friction and pulling. At the same time, it makes the air path layout neat, facilitates later inspection of the air path sealing, and reduces maintenance difficulty. Air hole 33: Located at the bottom of the shape adapter 34, it is connected to the vacuum pump 31. As a negative pressure transmission channel, it evenly applies the negative pressure generated by the vacuum pump to the bottom of the filter, ensuring that the filter is firmly adsorbed as a whole and avoiding insufficient local adsorption force that could cause the filter to warp and affect the flatness of the cut. Shape adapter 34: Fixed to the end of the positioning base plate 16 away from the motion platform 7, it can be replaced with a ring, rectangle, or irregular frame shape according to the shape of the filter. It has an air hole 33 at the bottom and a pressure sensor installed inside. Through the structure matching the contour of the filter, the filter is initially positioned; the replaceable design can adapt to multiple shaped filters and the replacement only takes 5 minutes, solving the defects of the fixed positioning structure of traditional equipment; the internal pressure sensor monitors the adsorption pressure in real time to ensure reliable positioning. Waste chip box 35: Fixed to the side surface of the cutting turntable 23, corresponding to the waste chip collection trough 24. It collects the cutting waste chips guided by the waste chip collection trough 24, and can be disassembled and cleaned periodically to prevent waste chips from accumulating and overflowing; by collecting waste chips in a centralized manner, the workload of cleaning the workshop environment is reduced, and at the same time, waste chips are prevented from entering the equipment and affecting the operation of the components.
