Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical product measurement technology, and in particular to a high-precision optical product thickness measurement device. Background Technology
[0002] Optical lenses are among the most critical optical products. To ensure the quality of optical lens manufacturing, thickness testing of the lenses or optical adhesive sheets is necessary during production to promptly screen for defective products or for quality control. Currently, the process for testing the thickness of optical adhesive sheets involves placing the sheet on a flat surface, using a dial indicator to measure the thickness at a starting position, then rotating the sheet at a certain angle to measure the thickness at the next position, and so on, until all positions have been measured. However, the frequent rotation of the sheet during measurement causes friction between the sheet and the table surface, leading to wear on the sheet surface, reduced measurement accuracy, and ultimately affecting product quality. Utility Model Content

[0006] A measurement platform, wherein an assembly bracket is provided on one side of the measurement platform and an installation cavity is provided in the middle of the test platform;
[0007] A measuring scale supported on the assembly bracket;
[0008] A lifting drive component is disposed within the mounting cavity;
[0009] A rotating platform fixed to the power output end of the lifting drive component, used to support the product to be tested;
[0010] When the product under test is carried on the rotating platform, its test position is directly below the measuring scale. When the lifting drive is in the extended state, the product under test is detached from the surface of the measuring platform. When the lifting drive is in the retracted state, the product under test is in contact with the surface of the measuring platform.
[0011] To implement the above technical solution, during use, the product to be tested is placed on the measuring platform, with its middle part corresponding to the rotating platform. After zeroing the measuring scale, the thickness at the initial position is measured. After measurement, the measuring head of the measuring scale is moved to a high position, and then the lifting drive is activated, driving the rotating platform to rise and lifting the product to be tested off the measuring platform. The rotating platform is then rotated so that the product to be tested rotates synchronously by a certain angle. The lifting drive is then activated again to lower the product to be tested back onto the measuring platform, and the thickness measurement at the next position can be performed. The above process is repeated until all positions are measured, thus completing the measurement of the product to be tested. By using the lifting drive to raise the product to be tested off the measuring platform and adjusting the rotation angle using the rotating platform, rotational friction between the product to be tested and the surface of the measuring platform is avoided, thus preventing wear on the product to be tested, ensuring measurement accuracy, and allowing for easy switching between rotation and measurement states, making the operation process more convenient.
[0012] In some exemplary embodiments, the measuring scale is a digital micrometer, and the surface of the measuring platform is used as the zero point for measurement.
[0013] The above technical solution makes the measurement and reading process more convenient.
[0014] In some exemplary embodiments, the lifting drive is connected to a foot pedal control switch, which is used to control the lifting drive to perform lifting actions.
[0015] The above technical solution facilitates foot control by testing personnel.
[0016] In some exemplary embodiments, the measuring platform is further provided with a wire groove communicating with the mounting cavity, and the foot control switch is electrically connected to the lifting drive component through a control line, the control line being threaded through the wire groove.
[0017] Implementing the above technical solution facilitates wiring.
[0018] In some exemplary embodiments, the lifting drive is either a pneumatic cylinder or an electric cylinder.
[0019] In some exemplary embodiments, the rotating platform includes: a mounting base plate for assembly with the power output end of the lifting drive component, and a rotating support plate rotatably mounted on the mounting base plate.
[0020] To achieve the above technical solution, the mounting base is locked to the power output end of the lifting drive component, and the product under test can be rotated by rotating the support platform.
[0021] In some exemplary embodiments, the assembly bracket is provided with clamping fixtures for clamping and fixing the measuring scale.
[0022] Implementing the above technical solution facilitates the fixing of the measuring scale.
[0023] In some exemplary embodiments, the clamping fixture includes: a first fixing part for clamping and fixing the measuring scale, and a second fixing part for fixing to the assembly bracket, wherein the first fixing part is slidably assembled to the second fixing part.
[0024] By implementing the above technical solution, the measuring scale can be adjusted to different measuring positions, thereby meeting the measurement needs of products of different sizes and models.
[0025] In summary, compared with the prior art, this utility model has the following beneficial effects:
[0026] This utility model provides a high-precision optical product thickness measurement device, comprising: a measurement platform, an assembly bracket on one side of the measurement platform, and an installation cavity in the middle of the measurement platform; a measurement scale supported on the assembly bracket; a lifting drive component disposed in the installation cavity; and a rotating platform fixed to the power output end of the lifting drive component for supporting the product to be measured. When the product to be measured is supported on the rotating platform, its measurement position is directly below the measurement scale, and when the lifting drive component is in an extended state, the product to be measured is detached from the surface of the measurement platform; when the lifting drive component is in a retracted state, the product to be measured is in contact with the surface of the measurement platform. In use, place the product to be tested on the measuring platform, aligning its center with the rotating platform. After zeroing the measuring scale, measure the thickness at the initial position. After measurement, move the measuring head of the measuring scale to the high position. Then, the lifting drive activates, raising the rotating platform and lifting the product to be tested off the measuring platform. Rotate the rotating platform to make the product rotate synchronously at a certain angle. Then, the lifting drive activates again to lower the product back onto the measuring platform, allowing for the measurement of the thickness at the next position. Repeat the above process until all positions are measured, thus completing the measurement of the product. By using the lifting drive to raise the product to be tested off the measuring platform and adjusting the rotation angle via the rotating platform, rotational friction between the product and the measuring platform surface is avoided, thus preventing wear on the product and ensuring measurement accuracy. Furthermore, it allows for easy switching between rotation and measurement states, making the operation process more convenient. Attached Figure Description

[0034] 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.
[0035] Example 1
[0036] like Figures 1 to 3 As shown, this utility model embodiment provides a high-precision optical product thickness measurement device, including: a measurement platform 10, an assembly bracket 11 on one side of the measurement platform 10, and an installation cavity 12 in the middle of the test platform; a measurement scale 20 supported on the assembly bracket 11; a lifting drive component 30 disposed in the installation cavity 12; and a rotating platform 40 fixed to the power output end of the lifting drive component 30 for supporting the product 60 to be measured; when the product 60 to be measured is supported on the rotating platform 40, its measurement position is directly below the measurement scale 20, and when the lifting drive component 30 is in the extended state, the product 60 to be measured is detached from the surface of the measurement platform 10; when the lifting drive component 30 is in the retracted state, the product 60 to be measured is in contact with the surface of the measurement platform 10.
[0037] Specifically, the measuring platform 10 can be a marble platform, and the upper surface of the measuring platform 10 must be flat and smooth. The mounting bracket 11 is fixed to the marble platform with screws. The measuring scale 20 is a digital micrometer, and the surface of the measuring platform 10 is used as the zero point for measurement, so as to make the measurement reading process more convenient. The mounting bracket 11 is provided with a clamping fixture 50 for clamping and fixing the measuring scale 20, so as to fix the measuring scale 20. The clamping fixture 50 can be fixed to the measuring scale 20 by screw connection, and the clamping fixture 50 and the mounting bracket 11 are locked and fixed by bolt assembly.
[0038] The lifting drive component 30 can be either a pneumatic cylinder or an electric cylinder. Preferably, the lifting drive component 30 is a pneumatic cylinder, which allows for faster operation. The lifting drive component 30 is connected to a foot control switch 31, which is used to control the lifting drive component 30 to perform lifting actions, so that the testing personnel can control it by foot. The measuring platform 10 is also provided with a wiring groove 13 that communicates with the mounting cavity 12. The foot control switch 31 is electrically connected to the lifting drive component 30 through a control line 32, which is run through the wiring groove 13 to facilitate wiring. It can be understood that when the lifting drive component 30 is a pneumatic cylinder, its air supply pipe can also be run through the wiring groove 13. The wiring groove 13 can be located in the middle of the measuring platform 10 or on the bottom surface of the measuring platform 10.
[0039] The rotating platform 40 includes: a mounting base plate 41 for assembly with the power output end of the lifting drive component 30, and a rotating support 42 rotatably mounted on the mounting base plate 41. The rotating support 42 and the mounting base plate 41 can be rotatably connected, for example, by a high-precision bearing. The mounting base plate 41 is locked to the power output end of the lifting drive component 30 with screws. The product under test 60 can be rotated by rotating the support 42.
[0040] In use, the product to be tested 60 is placed on the measuring platform 10, with its middle part corresponding to the rotating platform 40. After the measuring scale 20 is zeroed, the thickness at the initial position is measured. After measurement, the measuring head of the measuring scale 20 is moved to a high position. Then, the lifting drive 30 is activated, driving the rotating platform 40 to rise and lifting the product to be tested 60 off the measuring platform 10. The rotating platform 40 is then rotated so that the product to be tested 60 rotates synchronously at a certain angle. The lifting drive 30 is then activated again to lower the product to be tested 60 back onto the measuring platform 10, and the thickness measurement at the next position can be performed. The above process is repeated until all positions are measured, thus completing the measurement of the product to be tested 60. By using the lifting drive 30 to raise the product to be tested 60 off the measuring platform 10 and by using the rotating platform 40 to adjust the rotation angle, rotational friction between the product to be tested 60 and the surface of the measuring platform 10 is avoided, thus preventing wear on the product to be tested 60, ensuring measurement accuracy, and allowing for easy switching between rotation and measurement states, making the operation process more convenient.
[0041] Example 2
[0042] The difference between this embodiment and Embodiment 1 is that: Figure 4 and Figure 5 As shown, in this embodiment, the clamping fixture 50 includes: a first fixing part 51 for clamping and fixing the measuring scale 20, and a second fixing part 52 for fixing to the assembly bracket 11. The first fixing part 51 is slidably assembled to the second fixing part 52. The first fixing part 51 and the measuring scale 20 can be locked together by screws. The first fixing part 51 and the second fixing part 52 are slidably connected by a sliding block and a sliding rail that cooperate with each other. The second fixing part 52 and the assembly bracket 11 can be locked and fixed by a bolt assembly. The first fixing part 51 can be slidably adjusted on the second fixing part 52, so that the measuring scale 20 can be adjusted to different measurement positions, thereby meeting the measurement of products 60 of different sizes and models.
[0043] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
