Description

Technical Field

[0001] This utility model relates to the technical field of mobile phone component testing equipment, specifically a device for measuring the flatness of a mobile phone glass cover. Background Technology

[0002] The flatness of a mobile phone's glass cover is a core indicator of its manufacturing precision and has a decisive impact on the overall performance and user experience of the phone. During assembly, the quality of flatness directly affects the fitting accuracy between the cover and the body frame and display module. For phones with complex structures such as curved screens and foldable screens, flatness deviations in the cover can amplify assembly stress, increasing the risk of screen breakage.

[0003] In existing technologies, mobile phone glass cover flatness measuring devices typically use mechanical clamps to fix the cover plate to prevent displacement during measurement. However, this fixing method requires manual adjustment of the clamping force and position, increasing the number of steps and time spent loading the cover plate, thus reducing testing efficiency. Furthermore, after measurement, because the cover plate is tightly fitted to the surface of the placement table, the operator must manually remove the cover plate, which is also inconvenient. Therefore, this invention provides a flatness measuring device for mobile phone glass covers. Utility Model Content

[0022] 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.

[0023] Please see Figures 1-4 This utility model discloses a flatness measuring device for mobile phone glass covers, including a base 1 made of marble, which has good stability and shock resistance. A measuring sensor 7 is arranged above the base 1. The measuring sensor 7 is a laser displacement sensor, which has high measurement accuracy and can move laterally and longitudinally to achieve a comprehensive scan of the glass cover surface.

[0024] An infeed assembly 8 is provided at the center of the upper surface of the base 1 for automatically conveying the glass cover. A placement platform 9 is installed above the infeed assembly 8.

[0025] The infeed / outfeed assembly 8 includes a mounting bracket 81 fixedly mounted to the base 1. A lead screw 83, which is a ball screw, is rotatably connected to the inner side of the mounting bracket 81 via bearings and is driven by a motor 82. A mounting plate 85 is sleeved on the upper side of the mounting bracket 81 and is threadedly connected to the lead screw 83. The outer casing 91 is fixedly mounted on the upper end face of the mounting plate 85 by bolts. When the motor 82 drives the lead screw 83 to rotate, the mounting plate 85 drives the placement platform 9 to move axially along the lead screw 83.

[0026] Both sides of the mounting bracket 81 are provided with guide rails 84 that are fixedly connected to the base 1. The guide rails 84 are linear slide rails. The lower end face of the mounting plate 85 is slidably connected to the guide rails 84 on both sides through sliders. The guide rails 84 guide and support the movement of the mounting plate 85, ensuring that the placement platform 9 is moved smoothly.

[0027] The placement platform 9 includes an outer shell 91, which is made of aluminum alloy to reduce the overall weight. An inner liner 95 is fixedly installed inside the outer shell 91. The inner liner 95 is a sealed cavity structure, and a placement plate 92 is fixed to its upper end with bolts. The placement plate 92 is made of stainless steel and the surface is polished to prevent scratching the glass cover.

[0028] The inner side of the placement plate 92 is provided with multiple through holes arranged in a matrix. The placement plate 92 is embedded in the recessed part of the upper end face of the outer shell 91, which facilitates the stable placement of the glass cover.

[0029] Both the placement plate 92 and the inner liner 95 have slots in the middle. An ejection assembly 94 is installed inside the slot of the placement plate 92. The ejection assembly 94 is used to eject the glass cover for easy material removal. The ejection assembly 94 includes a connecting plate 941 that is fixed to the inside of the slot of the placement plate 92 by bolts. A cylinder 944 is installed on the lower end face of the connecting plate 941. The cylinder 944 is a small guide rod cylinder.

[0030] The extended end of cylinder 944 passes through connecting plate 941 and is fitted with top plate 942. Top plate 942 is made of polytetrafluoroethylene, which has good wear resistance and non-stick properties. Its size matches the size of the groove of inner liner 95. Guide rods 943 are fixedly connected to both sides of the lower end face of top plate 942. Guide rods 943 slide through connecting plate 941 to ensure that the lifting and lowering process of top plate 942 is stable and avoids tilting.

[0031] A filter screen 96, made of stainless steel, is installed between the inner liner 95 and the placement plate 92 to prevent glass shards or dust from entering the inner liner 95 and causing blockage. A vent pipe 93 extending from the outer shell 91 is connected to one side of the inner liner 95. The vent pipe 93 is connected to an external negative pressure device (such as a vacuum pump) via a flexible hose. During operation, the negative pressure device generates negative pressure inside the inner liner 95 through the vent pipe 93, which firmly adheres the glass cover to the placement plate 92 through the through-hole.

[0032] In this embodiment, support frames 2 are fixedly connected to both sides of the upper surface of the base 1. The support frames 2 are made of cast iron to ensure structural stability. A crossbeam 4 is slidably installed between the two support frames 2, and a movable seat 6 is slidably installed on the upper surface of the crossbeam 4. The measuring sensor 7 is fixedly connected to the movable seat 6 through a bracket.

[0033] A longitudinal movement module 3 is installed on the outer side of a support frame 2. The longitudinal movement module 3 is a linear module, including a servo motor, a ball screw, and a guide rail, used to drive the crossbeam 4 to move longitudinally along the support frame 2. A transverse movement module 5 is installed on the upper end face of the crossbeam 4. The transverse movement module 5 is also a linear module, used to drive the moving seat 6 to move laterally along the crossbeam 4. Through the coordinated action of the longitudinal movement module 3 and the transverse movement module 5, the two-dimensional movement of the measuring sensor 7 in the horizontal plane is realized.

[0034] The working principle and usage process of this utility model are as follows: During use and measurement, the glass cover plate is automatically moved to the measurement area through the inlet and outlet assembly 8. The negative pressure device generates negative pressure in the inner liner 95 through the vent pipe 93, and the glass cover plate is adsorbed and fixed through the through hole of the placement plate 92 to prevent displacement during the measurement process.

[0035] Driven by the longitudinal movement module 3 and the lateral movement module 5, the measuring sensor 7 moves along the lateral and longitudinal directions to perform a full scan of the glass cover surface and obtain flatness data.

[0036] After the measurement is completed, the feeding and discharging assembly 8 moves the placement platform 9 back to its initial position, and the ejection assembly 94 lifts up the glass cover for easy material removal.
