Description

Technical Field

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

[0002] In the era of rapid development of smartphones, the quality of the phone's glass cover, as an important component of the phone screen, directly affects the phone's appearance, feel, and lifespan. As consumers' demands for phone quality continue to increase, phone manufacturers are becoming increasingly strict in their quality control of the glass cover, especially the inspection of the glass cover's sides. The sides of the phone's glass cover must not only withstand the impacts and friction of daily use, but also ensure a perfect fit with the phone's frame. Therefore, its quality requirements are high. Any minor scratches, cracks, or dimensional deviations may lead to problems such as screen breakage, dust ingress, and water seepage during phone use, seriously affecting the user experience.

[0003] However, early inspection methods mainly relied on manual visual inspection. Inspectors checked the sides of the glass cover one by one with their eyes and experience. Due to eye fatigue and subjectivity, it was easy to miss or misidentify, especially for some minor scratches and cracks, which were difficult for the human eye to accurately identify, resulting in defective products entering the market. Some factories used simple calipers and magnifying glasses to assist in inspection, but these devices had limited functions and could only detect the size of the glass cover and some obvious defects. They could not accurately detect the surface quality of the glass cover. To address the above problems, a mobile phone glass cover inspection device was proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a mobile phone glass cover detection device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile phone glass cover detection device, comprising a housing, a partition fixedly connected to the inner surface of the housing, a top platform fixedly connected to the outer top of the housing, a bottom box fixedly connected to the inner bottom of the housing, a sliding groove horizontally formed on the outer top wall of the bottom box, a telescopic cylinder fixedly connected to the bottom inner side of the bottom box, a rack fixedly connected to the outer top surface of the telescopic cylinder, sector gears movably connected to the outer surfaces of both sides of the rack, a rotating shaft fixedly connected to the inner surface of the sector gears, a locking rod movably connected to the outer side of one side of the rotating shaft, a connecting rod fixedly connected to the outer top of the rotating shaft, a locking shaft engaging with the outer top surface of the connecting rod, and a clamping piece fixedly connected to the outer surface of one side of the locking shaft.

[0006] As described above, the bottom box is located at the center of the bottom of the box body, the top of the bottom box extends through the top of the partition, the rack has evenly distributed tooth grooves symmetrically opened on both sides, the rack and the sector gear are meshed and driven, the rotating shaft is fixed to the tail end of the sector gear, and the sector gear is symmetrically distributed on both sides of the rack.

[0007] As described above, the locking rod is a hollow tubular structure, the rotating shaft is rotatably connected inside the locking rod, the bottom end of the locking rod is fixed to the inner surface of the base box, the connecting rod passes through the inside of the sliding groove and is connected to the clamping piece, and the connecting rod is slidably connected inside the sliding groove.

[0008] As described above, support columns are fixedly connected to the top two sides of the partition, slide rails are fixedly connected to the top inner side of the support columns, a movable frame is slidably connected to the outer surface of the slide rails, and a laser scanning head is fixedly connected to the bottom outer side of the movable frame.

[0009] As described above, the opposite side surface of the clamping piece is made of soft rubber. The clamping piece is positioned below the laser scanning head, and the rubber on the inner side of the clamping piece holds the two sides of the mobile phone glass cover, ensuring the stability of the glass cover during the testing process.

[0010] As described above, a motor is fixedly connected to the top outer side of the top platform, a fan is fixedly connected to the bottom outer surface of the motor, a trough is provided at the bottom of the fan, a screen is fixedly connected to the upper and lower ends of the partition, the screen is located on the outside of the bottom box, a dust collection trough is provided at the bottom of the screen, and the dust collection trough is opened inside the bottom of the box.

[0011] As described above, the fan is rotatably connected to the inside of the top platform, the trough is opened on the bottom outer wall of the top platform, and the screen is set below the trough. The motor drives the fan to rotate, and the airflow generated by the fan rotates blows downwards, passing through the trough and the screen, blowing the impurities on the glass cover plate into the dust collection trough, keeping the detection environment clean and avoiding dust from interfering with the laser scanning detection results.

[0012] Compared with existing technologies, this mobile phone glass cover detection device has the following advantages:

[0013] I. This utility model uses a telescopic cylinder to drive a rack and a sector gear to mesh and transmit power. The rise of the rack causes the sector gear to start rotating around the shaft. At the same time, the rotation of the sector gear is transmitted to the clamping plates through the connecting rod, causing the two clamping plates to move relative to each other. The rubber on the inner side of the clamping plates clamps the two sides of the mobile phone glass cover, ensuring that the glass cover is stably clamped. The soft rubber on the inner side of the clamping plates ensures the clamping force and avoids damage to the surface of the glass cover, providing a stable foundation for the detection of the laser scanning head.

[0014] Second, this utility model uses an electric motor to drive a fan to generate airflow, which passes through a trough and a screen to blow impurities on the surface of the glass cover into a dust collection trough. This avoids dust scattering and interference with the laser beam, making the reflected light received by the laser scanning head purer. As a result, scratches and cracks on the surface of the glass cover can be detected more accurately, thus improving the detection accuracy.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-4As shown, this utility model provides a technical solution: a mobile phone glass cover detection device, including a housing 1, a partition 101 fixedly connected to the inner surface of the housing 1, a top platform 102 fixedly connected to the outer top of the housing 1, a bottom box 3 fixedly connected to the inner bottom of the housing 1, a sliding groove 301 horizontally opened on the outer top wall of the bottom box 3, a telescopic cylinder 302 fixedly connected to the bottom inner side of the bottom box 3, a rack 303 fixedly connected to the outer top of the telescopic cylinder 302, sector gears 304 movably connected to the outer surfaces of both sides of the rack 303, a rotating shaft 305 fixedly connected to the inner surface of the sector gears 304, a locking rod 306 movably connected to the outer side of one side of the rotating shaft 305, and a connecting rod 307 fixedly connected to the outer top of the rotating shaft 305. A snap-fit ​​shaft 308 is engaged with the outer surface of the end. A clamping piece 309 is fixedly connected to one side of the outer surface of the snap-fit ​​shaft 308. Support columns 2 are fixedly connected to the top two sides of the partition plate 101. A slide rail 201 is fixedly connected to the top inner side of the support column 2. A movable frame 202 is slidably connected to the outer surface of the slide rail 201. A laser scanning head 203 is fixedly connected to the bottom outer side of the movable frame 202. A motor 4 is fixedly connected to the top outer side of the top platform 102. A fan 401 is fixedly connected to the bottom outer surface of the motor 4. A trough 402 is provided at the bottom of the fan 401. A screen 403 is fixedly connected to the upper and lower ends of the partition plate 101. The screen 403 is located on the outside of the bottom box 3. A dust collection trough 404 is provided at the bottom of the screen 403. The dust collection trough 404 is opened inside the bottom end of the box 1.

[0023] Based on the overall structure of the device, the mobile phone glass cover to be tested is placed between the two clamping plates 309, ensuring that the side of the glass cover corresponds to the detection direction of the laser scanning head 203. Then, the telescopic cylinder 302 is activated, extending upward and driving the top rack 303 to move upward. The rack 303 meshes with the sector gears 304 on both sides, and the rise of the rack 303 causes the sector gears 304 to start rotating around the rotating shaft 305. At the same time, the rotation of the sector gears 304 is transmitted to the clamping plates 309 through the connecting rod 307, causing the two clamping plates 309 to move relative to each other. The rubber clamps on the inner side of the clamping plates 309 hold the hand. To ensure the stability of the glass cover during the inspection process, motor 4 is started, which drives fan 401 to rotate. The airflow generated by fan 401 blows downwards, passing through trough 402 and screen 403, blowing impurities on the surface of the glass cover into dust collection trough 404. This keeps the inspection environment clean and prevents dust from interfering with the laser scanning results. At this time, the position of moving frame 202 on slide rail 201 is adjusted so that moving frame 202 drives the laser scanning head 203 at the bottom to perform a full scan of the side of the mobile phone glass cover. By analyzing the reflected light, scratches and cracks on the surface of the glass cover are detected.

[0024] like Figure 1-4As shown, the bottom box 3 is located at the center of the bottom of the box body 1. The top of the bottom box 3 extends through the partition 101. The rack 303 has evenly distributed toothed grooves symmetrically distributed on both sides. The rack 303 and the sector gear 304 are meshed and driven. The rotating shaft 305 is fixed to the tail end of the sector gear 304. The sector gear 304 is symmetrically distributed on both sides of the rack 303. The locking rod 306 is a hollow tubular structure. The rotating shaft 305 is rotatably connected to the inside of the locking rod 306. The bottom end of the locking rod 306 is fixed to the inner surface of the bottom box 3. The connecting rod 307 extends through the inside of the slide groove 301 and is connected to the clamping piece 309. The connecting rod 307 is slidably connected to the inside of the slide groove 301. The opposite side surface of the clamping piece 309 is made of soft rubber material. The clamping piece 309 is located below the laser scanning head 203.

[0025] The telescopic cylinder 302 extends upward, driving the top rack 303 to move upward. The rack 303 meshes with the sector gears 304 on both sides for transmission. The rise of the rack 303 causes the sector gears 304 to start rotating around the rotating shaft 305. At the same time, the rotation of the sector gears 304 is transmitted to the clamping plates 309 through the connecting rod 307, causing the two clamping plates 309 to move relative to each other. The rubber on the inner side of the clamping plates 309 clamps the two sides of the mobile phone glass cover, ensuring the stability of the glass cover during the inspection process. At this time, the position of the moving frame 202 on the slide rail 201 is adjusted so that the moving frame 202 drives the laser scanning head 203 at the bottom to perform a full scan of the side of the mobile phone glass cover. By analyzing the reflected light, scratches and cracks are detected on the surface of the glass cover.

[0026] like Figure 1-4 As shown, the fan 401 is rotatably connected to the inside of the top platform 102, the trough 402 is opened on the bottom outer wall of the top platform 102, and the screen 403 is set below the trough 402.

[0027] The motor 4 drives the fan 401 to rotate. The airflow generated by the fan 401 blows downwards, passing through the trough 402 and the screen 403, blowing impurities on the glass cover plate into the dust collection trough 404, keeping the detection environment clean and preventing dust from interfering with the laser scanning detection results.

[0028] Working principle: The mobile phone glass cover to be tested is placed between two clamping plates 309, ensuring that the side of the glass cover corresponds to the detection direction of the laser scanning head 203. Then, the telescopic cylinder 302 is activated, extending upward and driving the rack 303 at the top to move upward. The rack 303 meshes with the sector gears 304 on both sides. The rise of the rack 303 causes the sector gears 304 to start rotating around the rotating shaft 305. At the same time, the rotation of the sector gears 304 is transmitted to the clamping plates 309 through the connecting rod 307, causing the two clamping plates 309 to move relative to each other. The rubber on the inner side of the clamping plates 309 clamps the two sides of the mobile phone glass cover, ensuring the stability of the glass cover during the testing process.

[0029] Next, motor 4 is started, which drives fan 401 to rotate. The airflow generated by fan 401 blows downwards, passing through trough 402 and screen 403, blowing impurities on the glass cover into dust collection trough 404, keeping the detection environment clean and preventing dust from interfering with the laser scanning detection results. At this time, the position of moving frame 202 on slide rail 201 is adjusted so that moving frame 202 drives the laser scanning head 203 at the bottom to perform a full scan of the side of the mobile phone glass cover. By analyzing the reflected light, scratches and cracks are detected on the surface of the glass cover.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
