Description

Technical Field

[0001] This utility model relates to the field of measuring fixture technology, specifically a short-side measuring fixture for improving measurement efficiency. Background Technology

[0002] In today's rapidly developing smartphone industry, the manufacturing precision of mobile phone lenses, as core imaging components, directly affects image quality and photographic quality. Parameters such as the short-side dimensional accuracy, surface roughness, and geometric tolerances of mobile phone lens components are key indicators for measuring product quality. Accurate testing of these parameters is crucial for ensuring product performance and enhancing market competitiveness.

[0003] Currently, when inspecting mobile phone lens parts, OMM (Optical Measuring Instrument) is used to accurately measure the dimensions of the parts. However, because the short side of mobile phone lens parts is small and narrow, it needs to be fixed vertically when fixing them. Therefore, tilting and inaccurate positioning are prone to occur during use. Thus, it is necessary to improve the measurement efficiency of the short side measuring fixture to solve the above problems. Utility Model Content

[0025] Example 1:

[0026] Please see Figure 1-3 This utility model provides a technical solution: a short-side measuring fixture for improving measurement efficiency, comprising an A-plate base 1 and a B-plate base 2. A lower positioning block 3 is provided on the top of the A-plate base 1, and an upper positioning block 4 is provided on the bottom of the B-plate base 2. The installation positions of the lower positioning block 3 and the upper positioning block 4 are parallel to the front of the A-plate base 1 and the B-plate base 2, thereby enabling the detection of the two long sides of the mobile phone lens component. A positioning pin 5 is fixedly installed on the top of the A-plate base 1, and a positioning hole 6 is opened on the bottom of the B-plate base 2. A first circular magnet 7 is fixedly installed inside the A-plate base 1 extending to the top, and a second circular magnet 8 is fixedly installed inside the B-plate base 2 extending to the bottom.

[0027] Furthermore, there are two positioning pins 5, which are symmetrically arranged with respect to the center line of the front of the A-plate base 1.

[0028] Furthermore, there are two positioning holes 6, which are symmetrically arranged with respect to the center line of the front side of the B plate base 2.

[0029] Furthermore, the position of the positioning pin 5 corresponds to the position of the positioning hole 6, and the positioning pin 5 is inserted into the inside of the positioning hole 6.

[0030] Thus, through the cooperation of positioning hole 6 and positioning pin 5, A plate base 1 and B plate base 2 can be positioned and docked, thereby achieving the fixation of mobile phone lens parts.

[0031] Furthermore, four first circular magnets 7 are provided, and two are arranged symmetrically around the center line of the front of the A plate base 1.

[0032] Furthermore, four second circular magnets 8 are provided, and two are arranged symmetrically around the center line of the front of the B plate base 2.

[0033] Furthermore, the first circular magnet 7 and the second circular magnet 8 have opposite magnetic properties, and the positions of the four first circular magnets 7 and the four second circular magnets 8 correspond to each other.

[0034] Thus, the A-plate base 1 and the B-plate base 2 are fixed by the attraction between the first circular magnet 7 and the second magnet, preventing them from separating during use.

[0035] Example 2:

[0036] Please see Figure 4-6 This utility model provides another technical solution: a short side measuring fixture for improving measurement efficiency, including an A-plate base 1 and a B-plate base 2. A lower positioning block 3 is provided on the top of the A-plate base 1, and an upper positioning block 4 is provided on the bottom of the B-plate base 2. The installation positions of the lower positioning block 3 and the upper positioning block 4 are perpendicular to the front of the A-plate base 1 and the B-plate base 2, thereby realizing the detection of the two short sides of the mobile phone lens parts. A positioning pin 5 is fixedly installed on the top of the A-plate base 1, and a positioning hole 6 is opened on the bottom of the B-plate base 2. A first round magnet 7 is fixedly installed inside the A-plate base 1 extending to the top, and a second round magnet 8 is fixedly installed inside the B-plate base 2 extending to the bottom.

[0037] Furthermore, there are two positioning pins 5, which are symmetrically arranged with respect to the center line of the front of the A-plate base 1.

[0038] Furthermore, there are two positioning holes 6, which are symmetrically arranged with respect to the center line of the front side of the B plate base 2.

[0039] Furthermore, the position of the positioning pin 5 corresponds to the position of the positioning hole 6, and the positioning pin 5 is inserted into the inside of the positioning hole 6.

[0040] Thus, through the cooperation of positioning hole 6 and positioning pin 5, A plate base 1 and B plate base 2 can be positioned and docked, thereby achieving the fixation of mobile phone lens parts.

[0041] Furthermore, four first circular magnets 7 are provided, and two are arranged symmetrically around the center line of the front of the A plate base 1.

[0042] Furthermore, four second circular magnets 8 are provided, and two are arranged symmetrically around the center line of the front of the B plate base 2.

[0043] Furthermore, the first circular magnet 7 and the second circular magnet 8 have opposite magnetic properties, and the positions of the four first circular magnets 7 and the four second circular magnets 8 correspond to each other.

[0044] Thus, the A-plate base 1 and the B-plate base 2 are fixed by the attraction between the first circular magnet 7 and the second magnet, preventing them from separating during use.

[0045] In actual operation, when this device is used, the mobile phone lens part is placed on the lower positioning block 3 of the A plate base 1, and then the positioning hole 6 on the B plate base 2 is aligned with the positioning pin 5 on the A plate base 1. The positioning pin 5 is then inserted into the positioning hole 6, so that the A plate base 1 and the B plate base 2 are positioned and connected. The upper positioning block 4 on the B plate base 2 cooperates with the lower positioning block 3 to position and fix the mobile phone lens part. Then, the A plate base 1 and the B plate base 2 are attracted and fixed by the attraction of the first round magnet 7 and the second round magnet 8.

[0046] During the inspection, A-plate base 1 and B-plate base 2 are laid flat, and the two edges of the mobile phone lens parts are inspected through the through grooves on the front and back of A-plate base 1 and B-plate base 2.

[0047] After the inspection is completed, repeat the above operation on the mobile phone lens part and install it in another measuring fixture to inspect the other two edges of the mobile phone lens part.
