Description

Technical Field

[0001] The invention belongs to the technical field of environmental protection mirror processing, and in particular relates to an air-floating detection line for processing a film-sprayed environmental protection mirror and a use method thereof. Background Art

[0002] In the field of magnetron sputtering coating of environmentally friendly mirrors, inspection is required after processing. However, the surface inspection of mirror materials has always faced many problems, including the following defects: (1) Currently, most conveyor lines use rollers (small wheels can be arranged linearly on the roller surface to reduce the contact area) or conveyor belts to transport mirrors. However, these are mechanical contacts, which can easily cause scratches or particle contamination on the surface of the mirror material. The mirror coating layer after magnetron sputtering is usually only a few microns thick, and the surface finish requirements are extremely high. Any slight mechanical contact may cause irreversible damage, especially for large-sized mirror materials, where the contact area is large and the damage risk is more prominent.

[0003] (2) Most existing inspection equipment can only inspect one side of the mirror material, while many application scenarios (such as double-sided coated glass) require comprehensive inspection of both the front and back sides of the material. The existing technical solution is to manually flip the material or add additional flipping stations, which not only significantly reduces production efficiency but also introduces the risk of secondary contamination and damage.

[0004] (3) The detection of mirror materials usually has high precision requirements (such as confocal microscopes, interferometers, etc.). These devices have extremely high requirements for the positioning accuracy and stability of the materials. The traditional transmission method with large vibration will cause blurred imaging and cannot meet the sub-micron detection requirements. Especially during high-speed transmission, the vibration problem is more prominent.

[0005] (4) Particles (especially metal particles) generated by mechanical friction in traditional conveying methods will contaminate the product surface, and the existing air flotation conveying technology cannot achieve stable multi-degree-of-freedom positioning and flipping functions.

[0006] Therefore, an innovative flip-over air-floating conveyable inspection line system was designed. Through the organic combination of non-contact transmission and intelligent flipping mechanism, non-destructive, efficient and comprehensive automated inspection of mirror materials was achieved. Summary of the Invention

[0007] The purpose of the present invention is to provide an air-floating detection line for the processing of film-sprayed environmentally friendly mirrors. By designing a new detection line, two conveyor lines are used for detecting the front and back sides of the mirror body respectively, and the flipping frame is used for flipping the mirror body. Through the design of the front air-floating platform and the rear air-floating platform, it can be ensured that the mirror body is in an air-floating state when the flipping frame and the two conveyor lines move. There is no mechanical contact and it can operate fully automatically. It can be completed online at one time without the need for worker intervention, which greatly reduces the damage to the mirror surface, improves product quality, improves the stability of mirror body transportation, and ensures the detection effect.

[0008] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is an air-floating detection line for processing a film-spraying and coating environmentally friendly mirror, comprising a front conveyor line, a rear conveyor line, a front air-floating table, a rear air-floating table and a turning frame; The front conveyor line and the rear conveyor line both include a platform, longitudinal beams are fixed on both sides of the top of the platform, and slide rails and racks are fixed on the top and inner side of the longitudinal beams respectively.

The plurality of air flotation units are linearly fixed to the top of the moving frame. Travel drives are fixed on both sides of the moving frame. The output end of the travel drive is connected to a gear. A plurality of linear modules are fixed to the bottom of both sides of the moving frame. The structural features of the rear air-floating platform are consistent with those of the front air-floating platform. The front air-floating platform moves along the front conveyor line. The rear conveyor line and the flipping rack share the rear air-floating platform. When the external longitudinal beam on the flipping rack is parallel to the ground rail and the external slide rail is located above, the external longitudinal beam, external slide rail and external rack are respectively positioned opposite and flush with the longitudinal beam, slide rail and rack on the rear conveyor line. A plurality of locking cylinders are linearly arranged on both sides of the rear air-floating platform, and the output ends of the locking cylinders are connected to fastening seats that match the fastening grooves.

[0009] Furthermore, the platform is a box-type platform or a frame-type platform, and an open area is provided at the bottom of the tail end of the platform on the front conveyor line. One end of the ground rail extends into the open area, and the height of the open area is higher than the upper surface of the rail car.

[0010] Furthermore, a rotary drive is provided in one of the side boxes, and a gear ring mechanism is provided between the rotary drive output end and the rotating shaft.

[0011] Furthermore, it also includes a reinforcement frame, which is installed at one end of the rear conveyor line close to the ground rail. Support beams are fixed on both sides of the top of the reinforcement frame. An electromagnet is fixed on the top surface of the support beam, and the upper surface of the electromagnet is flush with the lower surface of the longitudinal beam.

[0012] Furthermore, the adsorption unit includes a first junction box, a plurality of adsorption ports are linearly provided on the upper surface of the first junction box, a concave area is provided in the middle of the moving frame, and the lifting cylinder is installed between the first junction box and the concave area.

[0013] Furthermore, the air flotation unit includes a second combiner box, which is fixed on the top of the moving frame, and a plurality of air outlets are evenly arranged on the upper surface of the second combiner box.

[0014] Furthermore, the travel drive is fixed to the bottom of the moving frame through a mounting seat, and both the travel drive and the rotary drive are motor reducers.

[0015] Furthermore, the rotating shaft is located in the middle of the external longitudinal beam, and the distance between the rotating shaft and the upper surface of the rail car is greater than half the length of the rear air-floating platform and the external longitudinal beam.

[0016] Furthermore, a proximity switch is provided on the external slide rail, and a detection point cooperating with the proximity switch is provided on the moving frame of the rear air-floating platform.

[0017] A method for using an air-floating detection line for processing a spray-coated environmentally friendly mirror comprises the following steps: The SS01 lens is suspended on the surface of the front air-floating table by the buoyancy of the air-floating unit and the suction of the adsorption unit. The linear module of the front air-floating table sits on the slide rail of the front conveyor line. The front air-floating table moves along the slide rail to the rear conveyor line through the travel drive, gears and racks on the front conveyor line. It stops when it reaches the end of the front conveyor line and stops for inspection when it passes the inspection position. Initially, the linear module of the rear air-floating table sits on the external slide rail, and the gear of the rear air-floating table meshes with the external rack. At the same time, the locking cylinder is in the retracted state, and all fastening seats are respectively stuck in the corresponding fastening grooves. At this time, the two external slide rails of the rear air-floating table's moving frame and flip frame are in a fixed state. During the operation of SS03, the rail car moves the rear air flotation platform to the middle of the ground rail to provide space for the flipping of the rear air flotation platform. The rotary drive and gear ring mechanism in the side box control the rotating shaft and the rear air flotation platform to flip 180 degrees, so that the air flotation unit and adsorption unit are in a downward state. After the flip is completed, the rear air flotation platform is moved to the ground rail near the end of the front conveyor line by the rail car. SS04: After the lens is in place in SS01, the front air-floating platform is exactly below the rear air-floating platform. The air-floating unit and the adsorption unit on the rear air-floating platform are activated, and the extension of the lifting cylinder on the rear air-floating platform is increased to reduce the distance between the adsorption unit and the lens, thereby increasing the adsorption force on the lens to resist gravity. The air-floating unit and the adsorption unit on the front air-floating platform are stopped, thereby transferring the lens on the front air-floating platform to the rear air-floating platform. SS05 After the lens transfer is completed, the rear air-floating table is flipped 180 degrees according to the method in SS03 to turn the lens over. After the flip is completed, the rail car is driven to move to the ground rail near one end of the rear conveyor line; SS06: After the rail car moves into position, the external longitudinal beam, external slide rail and external rack on the flip frame are connected to the longitudinal beam, slide rail and rack of the rear conveyor line respectively. The bottom surface of the external longitudinal beam of the flip frame close to the rear conveyor line is in contact with the upper surface of the electromagnet, which activates the electromagnet to attract the external longitudinal beam and stabilize the position of the external longitudinal beam and the rear air floatation platform. SS07 controls the extension of the locking cylinder on the rear air-floating platform, releasing the lock between the fastening seat and the fastening groove. The rear air-floating platform is then transferred to the rear conveyor line via the travel drive, external rack, and external slide rail on the rear air-floating platform. After the transfer, the linear module of the rear air-floating platform sits on the slide rail of the rear conveyor line. The rear air-floating platform moves along the slide rail via the travel drive, gear, and rack on the rear conveyor line, stopping for inspection when it passes the inspection position. SS08 After one lens is transported, it controls each component to reset in preparation for the next lens.

[0018] The present invention has the following beneficial effects: The present invention designs a new type of detection line, which is mainly composed of two conveyor lines and a flipping frame. The two conveyor lines are respectively used for detecting the front and back sides of the mirror body, and the flipping frame is used for flipping the mirror body. Through the design of the front air floating platform and the rear air floating platform, it can be ensured that the mirror body is in an air floating state when the flipping frame and the two conveyor lines move. There is no mechanical contact and it can operate fully automatically. It is completed online in one go without the need for worker intervention, which greatly reduces the damage to the mirror surface, improves product quality, improves the stability of mirror body transportation, and ensures the detection effect.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] A method for using an air-floating detection line for processing a spray-coated environmentally friendly mirror comprises the following steps: The SS01 lens is suspended on the upper surface of the front air-floating platform 3 by the buoyancy of the air-floating unit 303 and the suction of the adsorption unit 302. The linear module 307 of the front air-floating platform 3 sits on the slide rail 103 of the front conveyor line 1. The front air-floating platform 3 moves along the slide rail 103 toward the rear conveyor line 2 via the travel drive 305, gear 306, and rack 104 on the front conveyor line 1. It stops when it reaches the end of the front conveyor line 1 and stops for inspection when it passes the inspection position. SS02 Initially, the linear module 307 of the rear air-floating platform 4 is seated on the external slide rail 506, and the gear 306 of the rear air-floating platform 4 is meshed with the external rack 507. At the same time, the locking cylinder 401 is in a retracted state, and all the fastening seats 402 are respectively locked in the corresponding fastening grooves 508. At this time, the moving frame 301 of the rear air-floating platform 4 and the two external slide rails 506 of the flip frame 5 are in a fixed state. During the operation of SS03, the railcar 502 moves the rear air flotation platform 4 to the middle of the ground rail 501 to provide space for the flipping of the rear air flotation platform 4. The rotary drive and gear ring mechanism in the side box 503 control the rotating shaft 504 and the rear air flotation platform 4 to flip 180 degrees, so that the air flotation unit 303 and the adsorption unit 302 are in a downward position. After the flip is completed, the rear air flotation platform 4 is moved to the end of the ground rail 501 near the front conveyor line 1 by the railcar 502. SS04: After the lens is in place in SS01, the front air-floating platform 3 is located directly below the rear air-floating platform 4. The air-floating unit 303 and the suction unit 302 on the rear air-floating platform 4 are activated, and the lifting cylinder 304 on the rear air-floating platform 4 is extended. This reduces the distance between the suction unit 302 and the lens, increasing the suction force on the lens to resist gravity. The air-floating unit 303 and the suction unit 302 on the front air-floating platform 3 are then stopped, thereby transferring the lens from the front air-floating platform 3 to the rear air-floating platform 4. SS05 After the lens transfer is completed, the rear air-floating table 4 is flipped 180 degrees according to the method in SS03 to turn the lens over. After the flip is completed, the rail car 502 is driven to move to the end of the ground rail 501 close to the rear conveyor line 2; SS06 When the rail 501 is moved into position, the external longitudinal beam 505, external slide rail 506 and external rack 507 on the flipping frame 5 are respectively connected to the longitudinal beam 102, slide rail 103 and rack 104 of the rear conveyor line 2.

SS07 controls the extension of the locking cylinder 401 on the rear air-floating platform 4, releasing the lock between the fastening seat 402 and the fastening groove 508. The rear air-floating platform 4 is then transferred to the rear conveyor line 2 via the travel drive 305, the external rack 507, and the external slide 506 on the rear air-floating platform 4. After the transfer, the linear module 307 of the rear air-floating platform 4 sits on the slide 103 of the rear conveyor line 2. The rear air-floating platform 4 moves along the slide 103 via the travel drive 305, the gear 306, and the rack 104 on the rear conveyor line 2, stopping for testing when it passes the inspection position.

10. The method for using the air-floating detection line for processing a spray-coated environmentally friendly mirror according to any one of claims 1 to 9, characterized in that: The following steps are involved: The SS01 lens is suspended on the upper surface of the front air-floating platform (3) by the buoyancy of the air-floating unit (303) and the suction of the adsorption unit (302). The linear module (307) of the front air-floating platform (3) sits on the slide rail (103) of the front conveyor line (1). The front air-floating platform (3) moves along the slide rail (103) to the rear conveyor line (2) through the travel drive (305), the gear (306) and the rack (104) on the front conveyor line (1). When it reaches the end of the front conveyor line (1), it stops and stops for detection when it passes the detection position. SS02 Initially, the linear module (307) of the rear air-floating platform (4) sits on the external slide rail (506), and the gear (306) of the rear air-floating platform (4) is engaged with the external rack (507), while the locking cylinder (401) is in a retracted state, and all the fastening seats (402) are respectively stuck in the corresponding fastening grooves (508). At this time, the moving frame (301) of the rear air-floating platform (4) and the two external slide rails (506) of the flip frame (5) are in a fixed state; SS03 During the operation of SS01, the rail car (502) moves the rear air flotation platform (4) to the middle of the ground rail (501) to provide space for the flipping of the rear air flotation platform (4). The rotary drive and gear ring mechanism in the side box (503) control the rotating shaft (504) and the rear air flotation platform (4) to flip 180 degrees, so that the air flotation unit (303) and the adsorption unit (302) are in a downward state. After the flip is completed, the rear air flotation platform (4) is moved to the ground rail (501) near one end of the front conveyor line (1). SS04 After the lens is in place in SS01, the front air-floating platform (3) is just below the rear air-floating platform (4), the air-floating unit (303) and the adsorption unit (302) on the rear air-floating platform (4) are started, and the extension of the lifting cylinder (304) on the rear air-floating platform (4) is increased, thereby reducing the distance between the adsorption unit (302) and the lens, increasing the adsorption force on the lens to resist gravity, and stopping the air-floating unit (303) and the adsorption unit (302) on the front air-floating platform (3), thereby transferring the lens on the front air-floating platform (3) to the rear air-floating platform (4); SS05 After the lens transfer is completed, the rear air-floating platform (4) is flipped 180 degrees according to the method in SS03 to achieve the flipping of the lens. After the flipping is completed, the rail car (502) is driven to move to the ground rail (501) close to one end of the rear conveyor line (2); SS06 When the rail (501) car moves to its position, the external longitudinal beam (505), the external slide rail (506) and the external rack (507) on the flipping frame (5) are respectively connected to the longitudinal beam (102), the slide rail (103) and the rack (104) of the rear conveyor line (2), and the bottom surface of the external longitudinal beam (505) of the flipping frame (5) close to the rear conveyor line (2) is in contact with the upper surface of the electromagnet (602), and the electromagnet (602) is activated to absorb the external longitudinal beam (505), thereby stabilizing the position of the external longitudinal beam (505) and the rear air-floating platform (4); SS07 controls the extension of the locking cylinder (401) on the rear air-floating platform (4), releases the lock between the fastening seat (402) and the fastening groove (508), and controls the rear air-floating platform (4) to be transferred to the rear conveyor line (2) through the travel drive (305), the external rack (507) and the external slide rail (506) on the rear air-floating platform (4). After the transfer, the linear module (307) of the rear air-floating platform (4) sits on the slide rail (103) of the rear conveyor line (2). The rear air-floating platform (4) moves along the slide rail (103) through the travel drive (305), the gear (306) and the rack (104) on the rear conveyor line (2), and stops for detection when passing the detection position; SS08 After one lens is transported, it controls each component to reset in preparation for the next lens.
