Description

Technical Field

[0001] This utility model relates to the field of optical disc cleaning and testing technology, and in particular to a cleanliness testing device for glass discs. Background Technology

[0002] Optical discs are a type of storage medium that uses glass as a substrate. They feature high storage density, long lifespan, and low cost. Compared to traditional plastic-based optical discs, glass discs have better chemical stability and mechanical properties. During the optical disc recording process, if the data on the disc is damaged or the recording is incomplete, the disc needs to be recycled and its surface photoresist cleaned before the data is re-recorded. After the initial cleaning steps, to ensure the cleaning quality, the disc needs to be sent to a testing fixture for inspection to ensure the accuracy of the next data recording.

[0003] Currently, Chinese Patent CN100339681C discloses an optical disc inspection device, which includes a carrier, a light source, a prism, a light sensor, and a display screen. The carrier holds the optical disc, the light source is adjacent to the carrier and located below the disc, emitting light. The prism is positioned between the disc and the light source; the light passes through the prism and illuminates the disc. The light reflected from the disc is then refracted by the prism. The light sensor receives and analyzes the refracted light. Compared to existing technologies, this device shortens the distance between the light source and the disc, and by utilizing prism refraction, reduces the size of the optical disc inspection device, thereby reducing the space cost required for mechanical equipment. Furthermore, this invention can detect whether the optical disc is warped or deformed, thus increasing the product yield rate.

[0004] However, the above-mentioned testing equipment has limitations in the testing process. Although the equipment uses a light source detection method, its detection principle is to analyze the incident and refraction angles after the light source is refracted in order to obtain the degree of warping of the optical disc surface. This method can only be used to detect the shape and cannot be directly used to detect the cleanliness of the glass disc. Utility Model Content

[0005] In view of the above situation and to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a cleanliness detection device for glass plates. The above technical objective is achieved through the following technical solution:

[0006] A cleanliness testing device for glass discs includes a testing platform. A placement tray is positioned above the testing platform, and an upwardly positioned tray-arranging column is fixed at the center of the placement tray. Stacked glass discs to be tested are placed above the placement tray. A testing gripper mechanism, mounted on the testing platform, is located on one side of the placement tray. The testing gripper mechanism includes a first glass disc support block, a second glass disc support block, and an electric gripper. The outer surfaces of the first and second glass disc support blocks have slots. One end of the first and second glass disc support blocks is mounted to the drive end of the electric gripper. A testing base, mounted on the top of the testing platform, is located on one side of the testing gripper mechanism. A testing base block is fixed to the upper end of the testing base. The interior of the testing base block has a testing groove, and two opposing light source generators and silicon photodiode sensors are located at both ends of the testing groove.

[0007] Furthermore, the detection gripper mechanism also includes a glass disk rotation motor, a glass disk reversing motor, and an adjusting cylinder. The glass disk rotation motor is mounted on one side of the electric gripper, and the electric gripper is fixed to the drive shaft end of the glass disk rotation motor. A motor mounting block is fixed on the other side of the glass disk rotation motor. A rotating base plate is fixed on the side wall of the motor mounting block. The rotating base plate is fixed to the drive shaft end of the glass disk reversing motor. A motor mounting plate is provided between the glass disk reversing motor and the adjusting cylinder. The motor mounting plate is fixed to the piston rod end of the adjusting cylinder.

[0008] Furthermore, a first Y-axis linear module is provided on one side of the adjusting cylinder, and a first X-axis linear module is provided on one side of the first Y-axis linear module. The first Y-axis linear module and the first X-axis linear module together form a two-axis conveying system for controlling the movement of the adjusting cylinder.

[0009] Furthermore, a gripping and moving mechanism is provided on the other side of the placement tray and installed above the testing platform. The gripping and moving mechanism moves the glass tray to be tested by gripping it with a suction cup. The gripping and moving mechanism includes a suction cup and a suction cup connecting rod, and the suction cup connecting rod is fixed to the upper end of the suction cup.

[0010] Furthermore, a second Y-axis linear module is provided on one side of the suction cup connecting rod, and a second X-axis linear module is provided on one side of the second Y-axis linear module. The second Y-axis linear module and the second X-axis linear module together form a dual-axis conveying system for controlling the movement of the suction cup connecting rod.

[0011] Furthermore, a transfer support plate is provided at the upper end of the detection platform, located between the gripping and moving mechanism and the detection gripper mechanism, and an auxiliary support bar is fixedly provided at the upper end of the transfer support plate.

[0012] In summary, this utility model has the following beneficial effects:

[0013] This invention features a high degree of automation. By having two independently operating handling systems work together, it achieves automatic handling and automatic detection functions, which helps improve the efficiency of cleanliness detection of optical disc glass substrates and provides a basis for the optical disc burning process.

[0014] The detection steps in this invention utilize the light transmittance of the glass plate as a criterion. By placing the glass plate in a counter-beam light source generator and sensor, and cooperating with a mechanical structure, all-round detection is achieved to obtain the light transmittance data of each position on the glass plate under test, thereby determining the cleanliness of the glass plate. This method of judgment is scientific and efficient, and its accuracy is greatly improved compared to human visual observation. Attached Figure Description

[0021] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figure 1 To be continued Figure 4 The detailed description of the embodiments will make this clear. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0022] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings. Example

[0023] A cleanliness testing device for glass plates includes a testing platform 1, which is the supporting platform of the device structure. A placement plate 2 is provided above the testing platform 1. An upwardly arranged plate-arranging column 3 is fixed at the center of the placement plate 2. Glass plates 4 to be tested are stacked on top of the placement plate 2. The central hole of the glass plates 4 to be tested is inserted into the plate-arranging column 3. During the testing process, the topmost set of glass plates will be taken away and tested.

[0024] A gripping and moving mechanism is installed on one side of the placement tray 2 above the testing platform 1. The gripping and moving mechanism mainly moves the glass tray 4 to be tested by gripping it with a suction cup 20. Therefore, the structure of the mechanism mainly includes a suction cup 20 and a suction cup connecting rod 21, with the suction cup connecting rod 21 fixed to the upper end of the suction cup 20.

[0025] In this embodiment, to improve the stability of the mechanism when gripping and adsorbing the glass plate, the device is provided with two sets of suction cups 20. The suction cup connecting rod 21 fixes the two sets of suction cups 20. When the suction cup connecting rod 21 moves, it synchronously drives the two sets of suction cups 20 to move.

[0026] A second Y-axis linear module 22 is provided on one side of the suction cup connecting rod 21, and a second X-axis linear module 23 is provided on one side of the second Y-axis linear module 22. The second Y-axis linear module 22 and the second X-axis linear module 23 together form a dual-axis conveying system for controlling the movement of the suction cup connecting rod 21. By adopting the above structure, the gripping and moving mechanism can achieve lateral and longitudinal movement adjustment under the action of the second Y-axis linear module 22 and the second X-axis linear module 23.

[0027] The upper end of the testing platform 1 is provided with a transfer support plate 24 located between the gripping and moving mechanism and the testing gripper mechanism. An auxiliary support bar 25 is fixedly provided on the upper end of the transfer support plate 24. The auxiliary support bar 25 supports the glass plate 4 to be tested. When the glass plate is placed above the auxiliary support bar 25, the center hole of the glass plate 4 to be tested is suspended in the air.

[0028] In this embodiment, the two sets of suction cups 20 are controlled by the second Y-axis linear module 22. After the suction cups 20 descend to the uppermost glass plate 4 to be tested, the gripping and moving mechanism will adsorb and grip the glass plate 4 to be tested. After the gripping is completed, the suction cups 20 rise and are transported to the upper part of the transfer support plate 24 under the control of the second X-axis linear module 23. Then the suction cups 20 descend again and gently place the glass plate 4 to be tested on the upper part of the auxiliary support bar 25.

[0029] A detection gripper mechanism is installed on one side of the placement plate 2 above the detection platform 1. The detection gripper mechanism includes a first glass plate support block, a second glass plate support block, and an electric gripper 7. The outer surfaces of the first and second glass plate support blocks are provided with slots. One end of the first and second glass plate support blocks is installed on the drive end of the electric gripper 7. Under the control of the electric gripper 7, after the glass plate 4 to be tested is supported by the auxiliary support bar 25, the suspended structure at the center of the glass plate 4 to be tested allows the first and second glass plate support blocks to be smoothly inserted into the center hole of the glass plate 4 to be tested. When the slots on the outer surfaces of the first and second glass plate support blocks are aligned with the center hole of the glass plate 4 to be tested, the electric gripper 7 controls the first and second glass plate support blocks to move outward and clamp the glass plate 4 to be tested through their slots.

[0030] The inspection gripper mechanism also includes a glass disk rotary motor 12, a glass disk reversing motor 13, and an adjusting cylinder 14. The glass disk rotary motor 12 is mounted on one side of the electric gripper 7, and the electric gripper 7 is fixed to the drive shaft end of the glass disk rotary motor 12. A motor mounting block 15 is fixed on the other side of the glass disk rotary motor 12. A rotating base plate 16 is fixed on the side wall of the motor mounting block 15. The rotating base plate 16 is fixed to the drive shaft end of the glass disk reversing motor 13. A motor mounting plate 17 is provided between the glass disk reversing motor 13 and the adjusting cylinder 14. The motor mounting plate 17 is fixed to the piston rod end of the adjusting cylinder 14.

[0031] A first Y-axis linear module 18 is provided on one side of the adjusting cylinder 14, and a first X-axis linear module 19 is provided on one side of the first Y-axis linear module 18. The first Y-axis linear module 18 and the first X-axis linear module 19 together form a two-axis conveying system for controlling the movement of the adjusting cylinder 14.

[0032] By adopting the above structure, the glass disk rotation motor 12, the glass disk reversing motor 13, and the adjusting cylinder 14 all provide the driving source basis for the fine-tuning movement of the glass disk 4 under test in each direction. The dual-axis conveying system of the first Y-axis linear module 18 and the first X-axis linear module 19 provides the movement control of the entire detection gripper mechanism. In the embodiment, the detection gripper mechanism lowers its height through the first Y-axis linear module 18, and the first glass disk support block and the second glass disk support block simultaneously extend into the center hole of the glass disk 4 under test. After the electric gripper performs the action of fixing the glass disk 4 under test, it takes the glass disk 4 under test above the auxiliary support bar 25 upward. Through the action of the glass disk reversing motor 13, the direction of the glass disk 4 under test is rotated by 90 degrees. Then, under the control of the first X-axis linear module 19, the glass disk 4 under test continues to move laterally.

[0033] A detection base 8 is installed on one side of the detection gripper mechanism and mounted on the upper end of the detection platform 1. A detection base block 9 is fixedly installed on the upper end of the detection base 8. A detection groove is provided inside the detection base block 9. A light source generator 10 and a silicon photodiode sensor 11 are arranged facing each other at both ends of the detection groove. The silicon photodiode sensor 11 is a photodetector made of silicon semiconductor material. Its working principle is to convert light signals into electrical signals.

[0034] When the glass disk 4 to be tested reaches one side of the detection groove, the adjusting cylinder 14 extends and controls one end of the glass disk 4 to be tested to move into the detection groove. At this time, the light source generator 10 in the detection base block 9 emits a fixed light source that passes through the surface of the glass disk 4 to be tested. The light source after penetration is received by the silicon photodiode sensor 11. The transmittance of the detection end of the glass disk 4 to be tested is obtained by analyzing the data. The glass disk rotation motor 12 controls the glass disk 4 to be tested to rotate at a uniform speed, which facilitates the detection of the entire surface of the glass disk 4 to be tested. The cleanliness of the glass disk 4 to be tested is analyzed and judged by the overall transmittance data.

[0035] The above description is a further detailed explanation of the present utility model in conjunction with specific embodiments, and it should not be considered that the specific implementation of the present utility model is limited to this. For those skilled in the art to which the present utility model pertains and related fields, any extensions, operation methods, and data substitutions made based on the technical solution concept of the present utility model should fall within the protection scope of the present utility model.
