Description

Technical Field

[0001] The utility model relates to the technical field of testing instruments, and more specifically to a mobile phone 3D cover curved surface tester. Background Art

[0002] Mobile phone curved cover plates are usually made of glass or plastic materials. They can adopt different curved designs, such as 2.5D curve, 3D curve, etc. During the manufacturing process, the mobile phone 3D cover plates need to be tested. Through such a curvature detection process, manufacturers can ensure that the quality of mobile phone curved cover plates meets the standards and improve the overall product appearance and performance.

[0003] The Chinese patent discloses a mobile phone 3D cover curved surface tester (authorization announcement number CN208688473U), including a lifting device and a curved surface contact device, the lifting device is composed of a test protection shell and a lifter, a fixed seat is provided at the middle position of the top of the inner top of the test protection shell, and a test pressing plate is provided at the bottom end of the lifting rod of the lifter, and the test pressing plate can make the mobile phone 3D cover plate not only prevent scratches on the surface of the mobile phone 3D cover plate when performing a curved surface test, but also prevent the mobile phone 3D cover plate from being broken due to excessive pressure during pressing, and the curved surface contact device is composed of a test workbench , a motor and a curved surface sensing head, a plurality of evenly distributed sleeves are arranged inside the test workbench, the motor rotates and fixes the second rotating rod, a first rotating rod is provided at the top of the second rotating rod, and a curved surface sensing head is provided at the top of the first rotating rod. The curved surface sensing head can be used to test the curved surface value of the mobile phone's 3D cover, but the device uses a pressing and holding method to fix the mobile phone's 3D cover. Since the two sides of the mobile phone's 3D cover are relatively thin and have a certain curvature as a whole, they are easily deformed during the press and clamping test, thereby affecting the accuracy of the test.

[0031] A sliding groove 4 is provided in the middle of the upper side of the device base 3, and a limiting slide 201 corresponding to the sliding groove 4 is fixedly installed on the lower side of the sliding housing 2. The sliding housing 2 is arranged in the sliding groove 4 through the limiting slide 201, so that the sliding housing 2 can move laterally within the range of the sliding groove 4, which is convenient for detecting the curvature of the mobile phone cover workpiece 1;

[0032] A first auxiliary rotating rod 24 is rotatably installed on the upper front side of the adjusting base 18, and a second auxiliary rotating rod 25 is rotatably installed on one side of the first auxiliary rotating rod 24 on the upper front side of the adjusting base 18.

[0033] A support base 11 is fixedly installed on the middle part of the upper side of the sliding shell 2, and a buffer groove 27 is opened in the middle part of the upper side of the support base 11. A support platform 10 is arranged on the upper side of the support base 11.

[0035] Working principle of the utility model: the operator rotates the limit bolt 203 counterclockwise to allow the first rotating wheel 19 and the second rotating wheel 20 to rotate and adjust, and then places the mobile phone cover workpiece 1 on the first suction cup 12 and the second suction cup 14. When the first suction cup 12 is subjected to force, the first adjusting member 16 and the first rotating rod 17 will drive the first rotating wheel 19 to rotate. Since the first rotating wheel 19 and the second rotating wheel 20 are meshed and connected, when the first rotating wheel 19 drives the second rotating wheel 20 to rotate, the second rotating rod 21, the second adjusting member 22 and the second rotating member 23 will drive the second suction cup 14 to rise and fall synchronously, so that the vertical heights of the first suction cup 12 and the second suction cup 14 can be adjusted. When the first suction cup 12 and the second suction cup 14 are adjusted to a suitable height, they can be adjusted according to the height. According to the curvature of the lower side of the mobile phone cover workpiece 1, the first suction cup 12 and the second suction cup 14 are rotated perpendicular to the bottom surface of the mobile phone cover workpiece 1 respectively. At this time, the first suction cup 12 and the second suction cup 14 adsorb and fix the mobile phone cover workpiece 1, and then the operator rotates the limit bolt 203 clockwise, and the limit bolt 203 is inserted into the threaded groove on the front side of the first rotating wheel 19 to lock the first rotating wheel 19 and the second rotating wheel 20. At this time, the mobile phone cover workpiece 1 is suspended and fixed to prevent the mobile phone cover workpiece 1 from deforming during the fixing process, and at the same time facilitate detection. Start the detector body 7, and then move the sliding shell 2 horizontally along the sliding groove 4. The detection probe 5 will fit the upper curved surface of the mobile phone cover workpiece 1 and gradually slide horizontally. At this time, the detector body 7 can calculate and detect the curvature.
