Cover glass strip streak detection device

Abstract

This utility model discloses a cover glass stripe detection device, relating to the field of glass inspection technology. It includes a detection base, a frame plate fixedly mounted on the top of the detection base, support frames fixedly mounted on both sides of the frame plate, a movable frame movably mounted inside the support frames, and a detection lens movably mounted on the surface of the movable frame. When the device is activated by a cylinder, pushing a sliding plate along a slide rail, the slider at the bottom of the sliding plate moves synchronously along a fixed sliding post. When the clamping plate approaches the edge of the workpiece, rotating the threaded sleeve pushes the threaded block to move laterally along the threaded post, thereby precisely adjusting the position of the clamping plate. This adapts to cover glass workpieces of different sizes and thicknesses, ensuring the clamping plate always fits tightly against the edge of the workpiece, preventing displacement or shaking, and ensuring the detection lens is always aligned with the preset detection area, significantly reducing detection errors caused by inaccurate positioning.

Description

Technical Field

[0001] This utility model relates to the field of glass testing technology, specifically to a cover glass stripe detection device. Background Technology

[0002] Cover glass is widely used on the display surfaces of electronic devices such as smartphones, tablets, and smartwatches, serving to protect the display and enhance its appearance. Various defects may occur during the production process of cover glass, among which streaks are relatively common and can affect the optical performance and appearance quality of the product.

[0003] Among the existing technical solutions, the publication number CN119104564A discloses an ultra-thin vehicle cover glass stripe detection device, which includes a support plate and a support frame; an ultra-thin glass flexible feeding mechanism, which is set on the support frame and is used to clamp and automatically feed the ultra-thin glass.

[0004] Traditional clamping mechanisms often use clamping components of fixed size, which can only be adapted to cover glass of specific specifications. When it is necessary to inspect processed parts of different sizes and thicknesses, the clamping fixtures need to be changed frequently. This is not only cumbersome and time-consuming, but also affects the positioning accuracy due to installation errors during the fixture replacement process. Utility Model Content

[0005] The purpose of this invention is to provide a cover glass stripe detection device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A cover glass stripe detection device includes a detection base, a frame plate fixedly installed on the top of the detection base, support frames fixedly installed on both sides of the frame plate, a movable frame movably installed inside the support frames, a detection lens movably installed on the surface of the movable frame, a transmission belt fixedly installed inside the frame plate, and a movable plate fixedly connected to the top of the transmission belt. Also includes: A clamping mechanism is disposed on the top of the movable plate and is used to clamp and fix the workpiece. A pushing mechanism is installed inside the movable plate and is used to push and lift the workpiece for loading and unloading.

[0007] A further improvement of the present invention is that the clamping mechanism includes a slide rail, with sliding plates movably mounted at both ends of the top of the slide rail, a cylinder fixedly connected to the right end of the sliding plate, a slider fixedly connected to the left end of the sliding plate, a fixed sliding column movably sleeved inside the slider, and a clamping plate fixedly connected to the bottom of the sliding plate.

[0008] A further improvement of this utility model is that threaded columns are fixedly installed at both ends of the inner side of the clamping plate, and threaded blocks are movably sleeved on the outer side of the threaded columns, and clamping plates are fixedly connected to the surface of the threaded blocks.

[0009] A further improvement of this utility model is that: threaded sleeves are threadedly connected to both ends of the clamping plate, and the right end of the threaded sleeve extends to the side of the threaded block.

[0010] A further improvement of this utility model is that a buffer column is fixedly installed on the inner side of the clamping plate, and a connecting block is fixedly connected to the telescopic end of the buffer column.

[0011] A further improvement of this utility model is that a protective plate is movably installed on the inner side of the clamping plate, and a rubber pad is fixedly installed on the surface of the protective plate.

[0012] A further improvement of the present invention is that the pushing mechanism includes a feeding plate, the bottom of which is fixedly mounted on the surface of a movable plate, a top plate is movably mounted inside the feeding plate, a driving plate is fixedly connected to the bottom of the top plate, a gear block is meshed on the side of the driving plate, and a rotary motor is fixedly connected inside the gear block.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a cover glass stripe detection device. When the cylinder is started, it pushes the sliding plate to slide along the slide rail. The slider at the bottom of the sliding plate moves synchronously along the fixed sliding column. When the clamping plate is close to the edge of the workpiece, the threaded block can be pushed to move laterally along the threaded column by rotating the threaded sleeve, thereby accurately adjusting the position of the clamping plate. This adapts to cover glass workpieces of different sizes and thicknesses, ensuring that the clamping plate is always in close contact with the edge of the workpiece, preventing displacement or shaking of the workpiece, and ensuring that the detection lens is always aligned with the preset detection area, significantly reducing the detection error caused by inaccurate positioning.

[0014] 2. This utility model provides a cover glass stripe detection device. When the protective plate contacts the edge of the workpiece, as the clamping action continues to advance, the reverse force generated by the workpiece on the protective plate will push the protective plate to squeeze the buffer column, causing it to undergo expansion and contraction deformation. The expansion and contraction characteristics of the buffer column can convert the instantaneous impact force during the clamping process into elastic potential energy, effectively offsetting the rigid impact caused by excessive thrust of the power component or excessive speed of movement, fundamentally avoiding physical damage such as chipping and scratches on the edge of the workpiece.

[0015] 3. This utility model provides a cover glass stripe detection device. A rotary motor drives a gear block to rotate, and the precise lifting and lowering of the top plate is achieved through the meshing transmission between the gear and the drive plate. When loading, the top plate extends to form a support platform higher than the bearing surface, allowing operators to directly and quickly place the workpiece. When unloading, the top plate extends again to lift the workpiece, facilitating quick pick-up and drop-off. The automated lifting method significantly shortens the operation time for loading and unloading, avoids the cumbersome process of bending over and leaning to pick up and drop parts, significantly shortens the detection cycle, and improves the overall detection efficiency of the device.

[0018] The present invention will be further described in detail below with reference to embodiments: like Figure 1-5 As shown, this utility model has the following three specific embodiments.

[0019] Example 1

[0020] This utility model provides a cover glass stripe detection device, including a detection base 1, a frame plate 2 fixedly installed on the top of the detection base 1, support frames 3 fixedly installed on both sides of the frame plate 2, a movable frame movably installed inside the support frame 3, a detection lens 4 movably installed on the surface of the movable frame, a transmission belt 5 fixedly installed inside the frame plate 2, and a movable plate 6 fixedly connected to the top of the transmission belt 5. Also includes: A clamping mechanism is located on the top of the movable plate 6 and is used to clamp and fix the workpiece. The pushing mechanism is located inside the movable plate 6 and is used to push and lift the workpiece for loading and unloading.

[0021] like Figure 1 As shown, the push mechanism is activated, and the internal push rod extends upward under the action of the power source, lifting the processed part on the top of the moving plate 6 to a certain height. The operator places the cover glass processed part to be tested in the preset area on the top of the moving plate 6, and then lowers it back to its original position. With the help of the clamping mechanism and the power provided by the air pump, the processed part is firmly fixed on the moving plate 6 by mechanical clamping force, so as to avoid detection errors caused by vibration or displacement during subsequent transportation and testing. After the material preparation is completed and the clamping and fixing are completed, the transmission belt 5 drives the moving plate 6 and the processed part to move towards the testing area at a uniform speed. The moving frame inside the support frame on both sides of the frame plate 2 starts synchronously. According to the size parameters of the processed part, it makes adaptive adjustments in the up and down and left and right directions along the track of the support frame, thereby driving the detection lens 4 on the surface to adjust to the preset detection position.

[0022] Example 2

[0023] The difference from Embodiment 1 is that this embodiment discloses a slide rail 61 and a feeding plate 7. The clamping mechanism includes a slide rail 61, with sliding plates 62 movably mounted at both ends of the top of the slide rail 61. A cylinder 66 is fixedly connected to the right end of the sliding plate 62, and a slider 64 is fixedly connected to the left end of the sliding plate 62. A fixed sliding post 65 is movably sleeved inside the slider 64. A clamping plate 63 is fixedly connected to the bottom of the sliding plate 62, and threaded posts 631 are fixedly mounted at both ends of the inner side of the clamping plate 63. Threaded posts 631 are movably sleeved on the outer side of the threaded posts 631. Block 632, the surface of the threaded block 632 is fixedly connected to a clamping plate 67, both ends of the clamping plate 63 are threadedly connected to threaded sleeves 634, the right end of the threaded sleeves 634 extends to the side of the threaded block 632, the pushing mechanism includes a feeding plate 7, the bottom of the feeding plate 7 is fixedly installed on the surface of the moving plate 6, a top plate 71 is movably installed inside the feeding plate 7, a drive plate 72 is fixedly connected to the bottom of the top plate 71, a gear block 73 is meshed on the side of the drive plate 72, and a rotary motor 74 is fixedly connected inside the gear block 73.

[0024] like Figure 2 , 3As shown in Figure 5, the rotary motor 74 drives the gear block 73 to rotate. The gear block 73 meshes with the drive plate 72 and drives it to move upward. The drive plate 72 pushes the top plate 71 to extend out from the inside of the loading plate 7, making it convenient for the operator to place the cover glass processing part to be inspected on the surface of the top plate 71. Then the rotary motor 74 rotates in the opposite direction, and through the meshing transmission between the gear block 73 and the drive plate 72, it drives the top plate 71 to retract into the inside of the loading plate 7, achieving the function of convenient loading and unloading. Then, the cylinder 66 starts and pushes the sliding plate 62 to slide inward along the top of the slide rail 61. At this time, the slider 64 at the bottom of the sliding plate 62 slides synchronously along the fixed slide post 65, providing guidance and limit for the movement of the sliding plate 62, ensuring its smooth movement. The sliding plate 62 drives the bottom fixed clamping plate 63 to move closer together until the clamping plate 67 is close to the edge of the workpiece. The threaded sleeves 634 at both ends of the clamping plate 63 can be rotated. The threaded sleeves 634 push the threaded block 632 to move laterally along the threaded post 631, thereby adjusting the position of the clamping plate 67 so that the clamping plate 67 is tightly fitted with the edge of the workpiece. The workpiece is firmly fixed by mechanical clamping force, avoiding detection errors caused by vibration or displacement during subsequent transportation and inspection.

[0025] Example 3

[0026] The difference from Embodiment 2 is that this embodiment discloses a protective plate 68 and a rubber pad 69. A buffer post 671 is fixedly installed on the inner side of the clamping plate 67, and a connecting block 672 is fixedly connected to the telescopic end of the buffer post 671. A protective plate 68 is movably installed on the inner side of the clamping plate 67, and a rubber pad 69 is fixedly installed on the surface of the protective plate 68.

[0027] like Figure 3 , 4 As shown, when the protective plate 68 on the inner side of the clamping plate 67 contacts the edge of the workpiece, as the sliding plate 62 continues to advance, the workpiece exerts a reverse force on the protective plate 68, pushing the protective plate 68 towards the clamping plate 67, thereby squeezing the buffer column 671 to contract. The telescopic characteristics of the buffer column 671 can effectively buffer the impact force during the clamping process, avoiding damage to the edge of the workpiece due to excessive thrust of the cylinder 66 or excessive movement speed. At the same time, the rubber pad 69 on the surface of the protective plate 68 is in direct contact with the workpiece. The elasticity and anti-slip properties of the rubber material not only further enhance the buffering effect, but also increase the friction with the workpiece, improve clamping stability, and prevent the workpiece from sliding or shifting during the clamping process.

[0028] The working principle of this cover glass stripe detection device will be explained in detail below.

[0029] like Figure 1-5As shown, the rotary motor 74 drives the gear block 73 to rotate. The gear block 73 meshes with the drive plate 72 and drives it to move upward. The drive plate 72 pushes the top plate 71 to extend out from the inside of the loading plate 7, making it convenient for the operator to place the cover glass processing part to be inspected on the surface of the top plate 71. Then the rotary motor 74 rotates in the opposite direction, and through the meshing transmission between the gear block 73 and the drive plate 72, it drives the top plate 71 to retract into the inside of the loading plate 7, achieving the function of convenient loading and unloading. Then, the cylinder 66 starts and pushes the sliding plate 62 to slide inward along the top of the slide rail 61. At this time, the slider 64 at the bottom of the sliding plate 62 slides synchronously along the fixed slide post 65, providing guidance and limit for the movement of the sliding plate 62, ensuring its smooth movement. The sliding plate 62 drives the bottom fixed clamping plate 63 to move closer together until the clamping plate 67 is close to the edge of the workpiece. The threaded sleeves 634 at both ends of the clamping plate 63 can be rotated. The threaded sleeves 634 push the threaded block 632 to move laterally along the threaded post 631, thereby adjusting the position of the clamping plate 67 so that the clamping plate 67 is in close contact with the edge of the workpiece. The workpiece is firmly fixed by mechanical clamping force. The transmission belt 5 drives the moving plate 6 and the workpiece to move at a uniform speed to the detection area. The moving frame inside the support frame on both sides of the frame plate 2 starts synchronously. According to the size parameters of the workpiece, it makes adaptive adjustments in the up and down and left and right directions along the track of the support frame, thereby driving the detection lens 4 on the surface to adjust to the preset detection position.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
