Description

Technical Field

[0001] The present invention relates to the technical field of glass cover plate processing, and particularly to an automatic polishing and detection device for glass cover plates, which is used for the surface treatment after rough polishing of glass cover plates. Background Art

[0002] Glass cover plates are widely used in various high-tech industries, and the surface cleanliness of glass cover plates is an important indicator for factory inspection.

[0003] In the surface treatment process of glass cover plates, steps such as rough grinding, fine grinding, fine polishing, cleaning, and detection are generally carried out in sequence. At present, each step of the surface treatment of most glass cover plates is carried out separately, which not only makes the overall process steps complex and the work efficiency low, but also results in high equipment costs and large equipment occupation space. The key lies in that there may be slight differences in the polishing processing degree of each glass cover plate, resulting in poor consistency of the surface brightness of each glass cover plate, or poor consistency of the surface polishing amount (too much or too little polishing). Although it does not affect the factory quality monitoring, for customers with high requirements for surface brightness consistency, this impact will be amplified and there will be problems with unqualified quality. Summary of the Invention

[0004] One advantage of the present invention is to provide an automatic polishing and detection device for glass cover plates, which is only for the glass cover plates after fine grinding. The automatic polishing and detection device integrates fine polishing treatment, cleaning treatment, and detection at the same time, can batch process multiple glass cover plates according to the same standard, thereby greatly improving the work efficiency, ensuring the consistency of the surface brightness of the glass cover plates, and thus making it more convenient to control the factory quality of the glass cover plates.

[0005] One advantage of the present invention is to provide an automatic polishing and detection device for glass cover plates. When performing fine polishing treatment, based on the surface brightness requirements of the glass cover plates, the glass cover plates can be processed by only one fine polishing wheel, or the glass cover plates can be processed by two fine polishing wheels with different polishing precisions in sequence to obtain higher precision, and the applicable range is wide.

[0006] One advantage of the present invention is to provide an automatic polishing and detection device for glass cover plates, which strictly controls the time of the cleaning operation and the time of the fine polishing operation, so that the time of the cleaning operation is less than or equal to the time of the fine polishing operation, thereby enabling the automatic polishing and detection device to operate continuously and efficiently, and can greatly improve the work efficiency.

Detailed implementation manners

[0030] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description can be applied to other implementation manners, variant schemes, improvement schemes, equivalent schemes, and other technical schemes that do not deviate from the spirit and scope of the present invention.

[0031] Those skilled in the art should understand that in the disclosure of the specification, the orientation or positional relationships indicated by the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present invention.

[0032] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, and in other embodiments, the number of the element can be multiple. The term "one" should not be construed as a limitation on the number.

[0033] Rough grinding means removing most of the surplus of the workpiece blank, and the final achieved effect should maintain a general geometric shape and roughness. Among them, rough grinding can improve the grinding efficiency and reduce the wear of the grinding tool, including processes such as deburring, flashing, rounding, removing oxide scale, rust removal, and strengthening the metal surface of the workpiece, leaving a balanced surplus for subsequent fine grinding;

[0034] Fine grinding means that after rough grinding, further fine grinding treatment is carried out to keep the workpiece in the most accurate geometric shape and with a fine crack depth, as the last process before polishing;

[0035] Fine polishing means that the final static polishing is performed on the workpiece to achieve a flat or mirror-like surface effect on the workpiece;

[0036] Among them, during the process of rough grinding and fine grinding, it may be necessary to change the shape or position of the workpiece, while fine polishing is mainly to polish the surface of the workpiece to make it flat or achieve a mirror-like effect, and generally there is no need to move or change the position of the workpiece.

[0037] An automatic polishing and inspection device for a glass cover plate according to a preferred embodiment of the present invention will be described in detail below. The automatic polishing and inspection device for the glass cover plate is only used for the surface treatment after the fine grinding of the glass cover plate and does not involve the rough grinding and fine grinding processes, so that the glass cover plate can be directly cleaned and inspected after fine polishing, so that fine polishing, cleaning and inspection can be integrated together. This can not only greatly reduce the procurement cost of each device, but also reduce the occupied space. The key is that it can also greatly improve the work efficiency and significantly improve the surface brightness consistency of each glass cover plate after batch processing, so as to meet the consistency of the factory products. Under the condition of meeting the quality inspection requirements, it can also meet the higher requirements of brightness consistency.

[0038] Specifically, refer to Figures 1 to 5, the automatic polishing and detection device for the glass cover plate includes a frame 10, a rotating disk 20, a fine polishing wheel 30, a cleaning disk 40 and a detection component. Among them, the rotating disk 20 is arranged inside the frame 10 and near the lower part. At the same time, a plurality of disk-shaped bases 21 are evenly distributed along the circumference on the top of the rotating disk 20. Among them, a plurality of fixture pads 22 are evenly arranged along the circumference on the top of the disk-shaped base 21 for respectively fixing the glass cover plate. Among them, the plurality of fixture pads 22 are evenly distributed radially with the center of the disk-shaped base 21 as the center of the circle. Among them, the fine polishing wheel 30 and the cleaning disk 40 are both located directly above the rotating disk 20 and are arranged on the frame 10 in a manner that can be driven to move up and down directionally. Among them, the detection component includes an image acquisition element 50 and a display screen. Among them, the image acquisition element 50, such as a vision detection lens, is located directly above the rotating disk 20 and has a plurality of image acquisition modules corresponding to the plurality of fixture pads 22 on the disk-shaped base 21 for respectively acquiring the surface information of the glass cover plate fixed on each fixture pad 22, such as brightness information or roughness information. At the same time, the image acquisition module is electrically connected to the display screen through an image processing system for real-time displaying the brightness information of the glass cover plate on each fixture pad 22 to confirm whether the polishing is qualified. If it is qualified, then turn it over for surface treatment on the other side, or take away the qualified glass cover plate and flow it into the next process. Among them, the fine polishing wheel 30, the cleaning disk 40 and the image acquisition element 50 are evenly distributed in sequence along the circumference in a manner corresponding to the disk-shaped base 21. Among them, in the circumferential rotation direction, the cleaning disk 40 is close to the image acquisition element 50, and a flexible shielding curtain 60 kept in a suspended state is arranged between the cleaning disk 40 and the image acquisition element 50 and the fine polishing wheel 30 to prevent the powder generated by polishing from splashing out of the polishing area and affecting the glass cover plate in the cleaning area (i.e., the area where the cleaning disk is located) or the detection area (i.e., the area where the image acquisition element is located). At the same time, through the flexible shielding curtain 60, a part of the polishing residues on the surface of the glass cover plate can also be removed, playing a role of pre-cleaning.

[0039] In the actual operation process, by controlling the rotating disk 20, the disk-shaped bases 21 on the rotating disk 20 can be respectively aligned with the fine polishing wheel 30, the cleaning disk 40 and the image acquisition element 50, and then the glass cover plate on the fixture pad 22 is sequentially subjected to fine polishing, cleaning and detection processing. At the same time, during the working process, it can finally make the glass cover plate cover all the fixture pads, thus forming a continuous, batch and same-standardized processing of the glass cover plate, and further effectively improving the processing efficiency of the glass cover plate, saving equipment costs and occupied space, and ensuring the consistency of the surface brightness of the glass cover plate on the premise of ensuring product quality.

[0040] In one embodiment, the disc-shaped base 21 has three or four. When the disc-shaped base 21 has four, two finishing wheels 30 are provided, and the polishing accuracies between the two finishing wheels 30 are different. The finishing wheel 30 with a lower polishing accuracy is closer to the image acquisition element 50, and the finishing wheel 30 with a higher polishing accuracy is closer to the cleaning disc 40. In this way, for a glass cover plate with a higher requirement for surface brightness, it can first be polished by the finishing wheel 30 with a lower polishing accuracy, then polished by the finishing wheel 30 with a higher polishing accuracy, and finally cleaned and inspected, and formed in one-time processing.

[0041] Preferably, a polyurethane environmental protection sponge is provided at the bottom of the cleaning disc 40.

[0042] Preferably, the flexible shielding curtain 60 is implemented as a rubber curtain.

[0043] In one embodiment, combined with Figure 4 , a first driving mechanism 70 for driving the finishing wheel 30 and the cleaning disc 40 to rotate directionally is provided on the frame 10. The first driving mechanism 70 includes a brushless motor 71, an L-shaped fixing seat 72, and a bearing seat 73. The L-shaped fixing seat 72 is provided on the frame 10. The brushless motor 71 is fixedly provided on the top of the horizontal portion 721 of the L-shaped fixing seat 72. At the same time, the bearing seat 73 is fixedly provided at the bottom of the horizontal portion 721. The output main shaft of the brushless motor 71 passes through the horizontal portion 721 and the bearing seat 73 and is coaxially and fixedly connected to the finishing wheel 30 or the cleaning disc 40, respectively for driving the finishing wheel 30 or the cleaning disc 40 to rotate directionally and at a constant speed.

[0044] Further preferably, combined with Figure 4 and Figure 5, a second driving mechanism 80 for driving the L-shaped fixing seat 72 to move vertically in a directed manner is further provided on the frame 10. Among them, the timing, moving speed, etc. of the vertical movement of the fine polishing wheel 30 and the cleaning disc 40 can be controlled separately or synchronously. The second driving mechanism 80 includes a fixing plate 81 and a stepping motor 82. The fixing plate 81 is fixedly arranged on the frame 10 along the vertical direction. The stepping motor 82 is vertically installed on the rear side of the fixing plate 81, and the output rotating shaft of the stepping motor 82 penetrates through the fixing plate 81 and is fixedly sleeved with a gear 821. At the same time, a guide rail 811 and a rack 812 extending along the vertical direction are arranged on the front side of the fixing plate 81. Generally, the guide rail 811 and the rack 812 are symmetrically distributed left and right with the gear 821 as the center. The rack 812 is meshed and cooperated with the gear 821 and is fixedly connected to the vertical portion 722 of the L-shaped fixing seat 72. At the same time, the guide rail 811 is slidably cooperated with the vertical portion 722 to play a guiding role. Thus, when the stepping motor 82 operates, the L-shaped fixing seat 72 can be driven to move vertically in a directed manner based on the cooperation between the gear 821 and the rack 812 and the sliding cooperation relationship between the guide rail 811 and the vertical portion 722.

[0045] Further preferably, a bellows cover 813 covering both the guide rail 811 and the rack 812 is further arranged on the front side of the fixing plate 81 for protecting the guide rail 811, the rack 812 and the gear 821, ensuring a good cooperation relationship between each component, and further ensuring the stability and reliability of the operation of the automatic polishing and detecting device.

[0046] It is worth mentioning that during the operation of the automatic polishing and detecting device, it is mainly divided into three processes, or three zones: fine polishing, cleaning and detecting. Among them, relying on the automated high-speed operation of the image acquisition element 50 and the image processing system, the brightness detection can be quickly carried out with the shortest time consumption. Therefore, in terms of affecting the production rhythm, the time of the cleaning operation and the time of the fine polishing operation are mainly considered. As a preferred embodiment, in order to maximize the work efficiency and meet the rhythm requirements of high-speed production, after the rotating disc 20 rotates a predetermined angle, the fine polishing wheel 30 and the cleaning disc 40 respectively perform the fine polishing operation and the cleaning operation. The time of the cleaning operation is less than or equal to the time of the fine polishing operation. When two fine polishing wheels 30 are provided, the time of the fine polishing operation is the sum of the fine polishing operation times of the two fine polishing wheels 30. In this way, it can be ensured that the automatic polishing and detecting device operates continuously without stagnation during the working process for a complete cycle, that is, a complete cycle of fine polishing, cleaning and detecting, enabling the automatic polishing and detecting device to always maintain the highest-speed working state, and thus greatly improving the work efficiency.

[0047] In one embodiment, a plurality of negative pressure air holes 201 are evenly formed in the top of the jig backing plate 22 for adsorbing and fixing the glass cover plate.

[0048] It should be noted that the terms "first" and "second" in the present invention are only used for descriptive purposes, do not represent any order, and cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0049] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the above principles, the embodiments of the present invention can have any deformation or modification.
