Description

Technical Field

[0001] The invention belongs to the technical field of glass cleaning equipment, and in particular relates to a cleaning line and a cleaning method for automobile glass. Background Art

[0002] After forming, the glass needs to be sprayed and cured on the concave surface to form a layer of infrared and ultraviolet isolation film. In order to improve the forming quality of the isolation film, the glass is usually cleaned before spraying to remove surface impurities. For example, the continuous production line of automobile glass washing machine and powder spraying machine disclosed in the Chinese utility model patent with application number 201620393454.4 connects the washing machine and the powder spraying machine through a continuous transport track, so that the cleaned glass can be directly put into the powder spraying process, thereby improving the film quality and film forming efficiency.

[0003] However, in actual use, it was found that the cleaning power of this type of glass cleaning equipment is poor, and tiny dust particles still exist on the glass surface after cleaning. For some spraying processes with extremely thin film thickness, if the cleanliness of the glass surface cannot meet the standard, it will seriously affect the appearance quality of the glass after spraying. Summary of the invention

[0004] The technical problem to be solved by the present invention is: how to provide a cleaning line for automobile glass to improve the cleanliness of the glass surface before spraying.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A car glass cleaning line comprises a polishing assembly, a roller brush assembly, a spray cleaning machine, a glass air drying machine, a flame treatment assembly and a spray air drying assembly which are arranged in sequence;

[0007] The roller brush assembly comprises a roller brush unit;

[0008] The roller brush unit comprises a water tank, a brush roller and a driving motor;

[0009] Part of the brush roller is arranged in the water tank;

[0010] The driving motor is arranged on the outside of the water tank, and the driving motor is drivingly connected to the brush roller.

[0011] Another technical solution of the present invention is: a method for cleaning materials using the above-mentioned automobile glass cleaning line, comprising the following steps:

[0012] S1, driving the polishing assembly to grind the surface of the product to be sprayed, and after grinding, transferring the product to be sprayed to the roller brush assembly;

[0013] S2, driving the roller brush assembly to initially wash the surface of the product to be sprayed, and after the initial washing, transporting the product to be sprayed to the spray cleaning machine;

[0014] S3, driving the spray cleaning machine to perform the first fine cleaning on the surface of the product to be sprayed, and after the first fine cleaning, transferring the product to be sprayed to the glass air drying machine;

[0015] S4, driving the glass air-drying machine to air-dry the surface of the product to be sprayed for the first time, and after the first air-drying, transporting the product to be sprayed to the flame treatment assembly;

[0016] S5, driving the flame treatment component to bake the to-be-sprayed surface of the to-be-sprayed product, and after baking, transporting the to-be-sprayed product to the spray air-drying component;

[0017] S6, driving the spray air-drying assembly to perform a second fine-washing and air-drying of the to-be-sprayed surface of the to-be-sprayed product. After the second fine-washing and air-drying, the cleaning work of the to-be-sprayed product is completed.

[0018] The beneficial effects of the present invention are as follows: the automobile glass cleaning line provided by the present invention needs to polish the surface of the glass before the glass passes through the spray cleaning machine and the glass air-drying machine for the first cleaning and air-drying, so as to improve the flatness of the glass surface and avoid the uneven thickness of the film layer after spraying due to surface potholes, and the polished surface of the glass is preliminarily cleaned by a roller brush assembly, so as to clean the most impurities with the minimum energy consumption, thereby achieving the effect of reducing the working pressure of subsequent cleaning equipment; at the same time, before entering the spray air-drying assembly for the second cleaning and air-drying, the glass surface needs to be instantly activated at high temperature by a flame treatment assembly, so as to deeply remove the residual organic matter on the glass surface, so that the impurities on the glass surface can be completely removed during the second cleaning and air-drying, thereby ensuring that the cleanliness of the glass surface can meet the requirements of the thin spraying process.

[0052] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0053] The cleaning power of existing glass cleaning equipment is poor, and tiny dust particles still exist on the glass surface after cleaning. For some spraying processes with extremely thin film thickness, if the cleanliness of the glass surface cannot meet the standard, it will seriously affect the appearance quality of the glass after spraying.

[0054] Based on this, please refer to Figures 1 to 21A cleaning line for automobile glass is proposed, comprising a polishing component, a roller brush component, a spray cleaning machine 6, a glass air drying machine 7, a flame treatment component and a spray air drying component 10 which are arranged in sequence; the roller brush component comprises a roller brush unit 5; the roller brush unit 5 comprises a water tank 51, a brush roller 52 and a driving motor 53; part of the brush roller 52 is arranged in the water tank 51; the driving motor 53 is arranged on the outside of the water tank 51, and the driving motor 53 is transmission-connected to the brush roller 52.

[0055] Specifically, it also includes a water replenishment valve 511 and a drain valve 512; the liquid outlet of the water replenishment valve 511 and the liquid inlet of the drain valve 512 are both connected to the water tank 51, so that the cleaning liquid in the water tank 51 can be replenished and discharged in time; if necessary, the water tank 51 can also be provided with a corresponding filter device and a reflux valve, and the water tank 51, the filter device and the reflux valve are connected in sequence to form a circulation loop, so that the cleaning liquid can be reused many times to achieve the effect of cost saving. This design makes specific improvements to the composition structure of the roller brush unit 5, and drives the brush roller 52 to rotate continuously along its own axis by driving the motor 53, so as to provide structural support for removing a large amount of grinding stains on the glass surface.

[0056] It can be understood that, in the cleaning line of automobile glass of the present invention, before the glass passes through the spray cleaning machine 6 and the glass air-drying machine 7 for the first cleaning and air-drying, it is necessary to first polish the surface of the glass to improve the flatness of the glass surface and avoid uneven thickness of the film layer after spraying due to surface pits, and the polished surface of the glass is preliminarily cleaned by the roller brush assembly to clean the most impurities with the minimum energy consumption, so as to reduce the working pressure of the subsequent cleaning equipment; at the same time, before entering the spray air-drying assembly 10 for the second cleaning and air-drying, the glass surface needs to be instantaneously activated at high temperature by the flame treatment assembly, so as to deeply remove the organic matter remaining on the glass surface, so that the impurities on the glass surface can be completely removed during the second cleaning and air-drying, thereby ensuring that the cleanliness of the glass surface can meet the requirements of the thin spraying process; and compared with the traditional cleaning process, the cleaning flow of the present invention can not only realize fully automatic cleaning, but also meet the needs of efficient cleaning, and after cleaning the glass, the air-drying dehydration method is adopted to replace the traditional drying dehydration, which ensures the dehydration effect while greatly saving the overall production energy consumption.

[0057] In some embodiments, the above-mentioned automobile glass cleaning line also includes a loading and positioning device 1; the polishing assembly includes a first industrial robot 2 and a polishing unit 3; the discharge end of the loading and positioning device 1 and the grinding end of the polishing unit 3 are both located within the moving range of the clamping end of the first industrial robot 2; the loading and positioning device 1 includes a first transmission device 101 and an image collector 102; the image collector 102 is arranged on one side of the first transmission device 101, and the scanning end of the image collector 102 and the transmission surface of the first transmission device 101 are arranged opposite to each other; the transmission surface of the first transmission device 101 is located within the moving range of the clamping end of the first industrial robot 2. Specifically, the loading and positioning device 1 can also be equipped with a corresponding fill light plate 103 when necessary to improve the acquisition clarity of the image collector 102, and the image collector 102 can also be electrically connected to the corresponding industrial robot through an external control system, so as to transmit the relevant position information of the glass to the corresponding industrial robot, ensuring that the industrial robot can accurately clamp the glass. This design further improves the composition structure of the cleaning line of the present invention. It is only necessary to place the glass to be cleaned in an orderly manner on the first transmission device 101, and then the imaging device scans and obtains the position information of the glass in sequence, and transmits the corresponding position information to the first industrial robot 2, so that the first industrial robot 2 can accurately clamp the glass and perform subsequent cleaning work, saving the time required for manual adjustment of the clamping position.

[0058] In some embodiments, the polishing unit 3 includes a support frame 31, a polishing liquid feeder 32 and a polishing assembly 33 disposed on the support frame 31; the liquid outlet of the polishing liquid feeder 32 and the polishing end of the polishing assembly 33 are both located within the moving range of the clamping end of the first industrial robot 2. Specifically, the polishing assembly 33 also includes a rotating table 31, and at least two polishing stations 332 disposed on the rotating table 31. When one of the polishing stations 332 needs to replace the polishing piece, the other polishing stations 332 can be rotated to a specified position through the rotating table 31 to ensure that the polishing work can proceed normally; the polishing liquid feeder 32 is any commercially available device that can automatically squeeze out the material inside the tank. This design makes specific improvements to the composition structure of the polishing unit 3. The first industrial robot 2 brings the glass surface to be sprayed close to the liquid outlet of the polishing liquid feeder 32, so that the polishing liquid is evenly applied to the surface of the glass. Then, along the set polishing route, the glass is reciprocated on the polishing end of the polishing assembly 33, so that the surface of the glass can be fully polished, thereby avoiding the problem of uneven film thickness during subsequent spraying due to surface potholes, which affects the overall appearance.

[0059] In some embodiments, the above-mentioned automobile glass cleaning line also includes a turntable 4; the roller brush assembly also includes a second industrial robot; the turntable 4 is arranged within the moving range of the clamping end of the first industrial robot 2 and the clamping end of the second industrial robot; the brush end of the brush roller 52 and the feeding end of the spray cleaning machine 6 are both located within the moving range of the clamping end of the second industrial robot. A mixture of polishing liquid and glass debris usually remains on the surface of the polished glass. In order to reduce the working pressure of the subsequent spray cleaning machine 6, the glass surface will be pre-cleaned by the roller brush unit 5 before entering the spray cleaning machine 6, so that a large amount of stains can be removed; since the moving range of the first industrial robot 2 is limited, and to avoid the first industrial robot 2 affecting the feeding rhythm due to the large amount of work to be performed, a corresponding second industrial robot is added to take over the roller brushing work of the glass. In order to enable the first industrial robot 2 and the second industrial robot to be smoothly handed over, a corresponding transfer table 4 is set at the intersection of their moving ranges, so that the first industrial robot 2 can first place the polished glass on the transfer table 4, and then the second industrial robot further clamps the glass, thereby ensuring the stability of clamping. If necessary, a corresponding image collector 102 can also be set on one side of the transfer table 4 to transmit the position information of the glass to the second industrial robot in real time, so as to improve the reliability of clamping.

[0060] In some embodiments, the spray cleaning machine 6 is provided with at least two spray channels; a first linear drive device 61 and a first spray rack 62 are provided in the spray channel; a first suction cup 611 is provided on the movable part of the first linear drive device 61, and the suction end of the first suction cup 611 can be adsorbed on one side of the thickness direction of the material; along the vertical direction, a first spray component 621 and a second spray component 622 are provided on the first spray rack 62; the movable part of the first linear drive device 61 can drive the material to pass between the spray end of the first spray component 621 and the spray end of the second spray component 622; a wind knife head 623 is also provided on the first spray rack 62; the air outlet end of the wind knife head 623 is arranged opposite to the other side of the thickness direction of the material. This design makes specific improvements to the composition structure of the spray cleaning machine 6. When the movable part of the first linear drive device 61 drives the product to be sprayed through the first spray rack 62, it can simultaneously clean both sides of the product to be sprayed in the thickness direction, so that the impurities remaining from the previous process can be cleaned; at the same time, during the spraying process, the wind knife head 623 also blows high-pressure gas to the surface of the product to be sprayed, thereby quickly drying the moisture on one side of the product, so as to provide structural support for the subsequent clamping equipment to reliably adsorb the product.

[0061] In some embodiments, the glass air-drying machine 7 is provided with an air-drying channel corresponding to the spray channel; a second linear drive device 71 and a first air knife frame 72 are provided in the air-drying channel; a second suction cup 711 is provided on the movable part of the second linear drive device 71, and the suction end of the second suction cup 711 is arranged opposite to the suction end of the first suction cup 611; along the vertical direction, a first air knife assembly 721 and a second air knife assembly 722 are provided on the first air knife frame 72; the movable part of the second linear drive device 71 can drive the material to pass between the air outlet end of the first air knife assembly 721 and the air outlet end of the second air knife assembly 722. Specifically, a telescopic device 712 is also provided on the movable part of the second linear drive device 71, and the second suction cup 711 is connected to the movable part of the telescopic device 712, and the second suction cup 711 can be driven to move toward the mold surface of the material through the telescopic device 712. This design makes specific improvements to the component structure of the glass drying machine 7. When the movable part of the second linear drive device 71 drives the product to be sprayed through the first wind knife rack 72, the moisture on both sides of the product to be sprayed can be quickly dried under the action of the high-pressure airflow of the first wind knife rack 72, thereby ensuring that the dryness of the surface can meet the processing requirements of the subsequent flame treatment process.

[0062] In some embodiments, the above-mentioned automobile glass cleaning line also includes a sealing device 8; the feeding end and the discharging end of the glass dryer 7 are both provided with a sealing device 8; the sealing end of the sealing device 8 can control the opening of the feeding end or the discharging end of the glass dryer 7; the sealing device 8 includes a sealing plate 81, a pressing cylinder 82 and a lifting cylinder 83 connected in sequence; the lifting cylinder 83 is connected to the glass dryer 7; the moving direction of the pressing cylinder 82 is perpendicular to the moving direction of the lifting cylinder 83; the moving direction of the pressing cylinder 82 is parallel to the moving direction of the material; the sealing plate 81 and the feeding end and / or the discharging end of the glass dryer 7 are arranged relative to each other; the pressing cylinder 82 can drive the sealing plate 81 to fit the feeding end or the discharging end of the glass dryer 7. By arranging corresponding sealing devices 8 at the feeding end and the discharging end of the glass drying machine 7, the interior of the glass drying machine 7 can be sealed when the glass drying machine 7 dries the moisture on the surface of the product to be sprayed, so as to prevent the high-pressure gas generated by the wind knife assembly from flowing into the external environment, thereby destroying the pressure balance system of the production workshop.

[0063] In some embodiments, the above-mentioned automobile glass cleaning line also includes a converging conveyor 9; the converging conveyor 9 includes a material transfer device 91, a conveyor belt 92, and a second transmission device 93 corresponding to the second linear drive device 71; the conveyor belt 92 is arranged between the second transmission device 93; the transmission surface of the conveyor belt 92 and the transmission surface of the second transmission device 93 are both arranged opposite to the material transfer end of the material transfer device 91; the transmission surface of the conveyor belt 92 and the transmission surface of the second transmission device 93 are both located within the moving range of the material transfer end of the material transfer device 91. Specifically, when necessary, the converging conveyor 9 can also be provided with a corresponding image collector 102 in combination with a corresponding industrial robot to improve the material clamping accuracy and facilitate the smooth transfer of the material to the equipment of the next process. The image collector 102 can also be provided to detect the surface quality of the material. When the material is unqualified, the material can be promptly pushed out of the cleaning process to avoid unnecessary time and material costs. This design can gather the products to be sprayed in multiple cleaning and air-drying processes onto the conveyor belt 92 by setting up a converging conveyor device 9, so that subsequent grabbing equipment can uniformly and orderly transport the products to be sprayed to the corresponding processing equipment.

[0064] In some embodiments, the flame treatment component includes a third industrial robot and a flame spray rack; the transmission surface of the conveyor belt 92, the spray end of the flame spray rack and the feeding end of the spray air-drying component 10 are all located within the moving range of the clamping end of the third industrial robot; the spray air-drying component 10 includes at least two spray air-drying channels; the spray air-drying channel includes a third linear drive device 1001, and a second spray rack 1002 and a second wind knife rack 1003 arranged in sequence along the moving direction of the material; a third suction cup 1004 is provided on the movable part of the third linear drive device 1001, and the suction end of the third suction cup 1004 and the suction end of the second suction cup 711 are arranged oppositely; in the vertical direction, a third wind knife assembly 1005 and a fourth wind knife assembly 1006 are provided on the second wind knife rack 1003; the movable part of the third linear drive device 1001 can drive the material to pass between the air outlet end of the third wind knife assembly 1005 and the air outlet end of the fourth wind knife assembly 1006. Specifically, the first industrial robot 2, the second industrial robot and the third industrial robot have similar structures, and are all commercially available devices that can achieve six-axis linkage, and the clamping ends of the three are all provided with corresponding suction cup devices 21; the feeding end and the discharging end of the spray air-drying component 10 can also be provided with corresponding sealing devices 8 to ensure the airtightness of the equipment. This design makes specific improvements to the composition structure of the flame treatment component, the composition structure of the spray air-drying component 10, and the positional relationship between the two, so that the product to be sprayed after flame treatment can quickly and smoothly enter the interior of the spray air-drying component 10 for deep cleaning, thereby ensuring that the surface cleanliness of the glass meets the spraying requirements.

[0065] In some embodiments, the above-mentioned automobile glass cleaning line also includes a material dividing and collecting device 11; the material dividing and collecting device 11 includes a main conveying device 111, a material dividing and collecting device 112 and a rotating material transfer device 113; both sides of the main conveying device 111 are provided with a material dividing and collecting device 112; the movable part of the main conveying device 111 and the movable part of the material dividing and collecting device 112 are both provided with a fourth suction cup; a rotating material transfer device 113 is provided between the main conveying device 111 and the material dividing and collecting device 112; the moving path of the movable part of the main conveying device 111 and the moving path of the movable part of the material dividing and collecting device 112 both intersect with the rotating path of the movable part of the rotating material transfer device 113; the moving path of the movable part of the main conveying device 111 and the moving range of the clamping end of the third industrial robot intersect; the feeding end and the discharging end of the spray air-drying component 10 are both provided with a material dividing and collecting device 11; the material dividing and collecting device 11 is connected to the feeding end or the discharging end of the spray air-drying component 10 through the material dividing and collecting device 112. Specifically, the main conveying device 111 and the material distribution conveying device 112 are any commercially available devices that can drive an object to move back and forth in a straight line, such as a linear guide or a pneumatic guide; the rotary material transfer device 113 is any commercially available device that can drive an object to perform a planar rotational motion, such as a rotary downward pressure cylinder. By providing corresponding material distribution and collection devices 11 at both the feed end and the discharge end of the spray air-drying component 10, the products to be sprayed can be orderly dispersed to the corresponding cleaning process, thereby effectively improving the cleaning rhythm; at the same time, after cleaning and air-drying, the products to be sprayed in different processes are aggregated on the same conveying device, which can facilitate the subsequent spraying work, that is, only the spraying angle of the corresponding spraying device needs to be adjusted and fixed once, and then the ordered products to be sprayed are sequentially conveyed through the spraying device, so that the overall spraying work can be completed efficiently.

[0066] The present invention also provides a method for cleaning materials using the above-mentioned automobile glass cleaning line, comprising the following steps:

[0067] S1, driving the polishing assembly to grind the surface of the product to be sprayed, and after grinding, transferring the product to be sprayed to the roller brush assembly;

[0073] Specifically, the automobile glass processed by the present invention is usually a curved surface, so the automobile glass of the present invention has a posture with the convex surface facing upward and the concave surface facing downward when passing through the loading and positioning device 1, the spray cleaning machine 6, the glass air drying machine 7 and the merging and conveying device 9; and has a posture with the concave surface facing upward and the convex surface facing downward when passing through the material dividing and gathering device 11, the spray air drying component 10 and the subsequent spraying equipment.
