Description
Technical Field
[0001] The utility model relates to the technical field of automobile film processing and detection, in particular to a black film etching depth measuring device. Background Technique
[0002] Automobile films mainly refer to a thin film-like object attached to the front and rear windshield, side windows and sunroof of a vehicle, and this thin film-like object is also called a solar film or a heat insulation film. The main functions of automobile films are to block ultraviolet rays, block part of the heat, prevent injury caused by flying glass, prevent glare, etc. At the same time, according to the one-way perspective performance of the solar film, the purpose of protecting personal privacy can be achieved. In addition, it can also reduce the damage to the items and personnel in the vehicle caused by ultraviolet radiation, reduce the temperature in the vehicle through physical reflection, reduce the use of the automobile air conditioner, thereby reducing fuel consumption and saving a part of the expenses.
[0003] The purpose of etching is to transfer the photoresist pattern obtained by photolithography to the thin film on the surface of the wafer, that is, by using the covering and protection of the photoresist film, to remove the thin film without photoresist protection by chemical reaction or physical action to complete the purpose of pattern transfer. The etching process is mainly divided into wet etching process and dry etching process.
[0004] As a typical representative of dry etching, when laser etching is carried out on automobile films, by controlling the laser frequency and irradiation duration, the black color of the black film is corroded (the film at the black film position does not change, but the color on the film is decomposed, just like the situation that a normal outdoor billboard fades after a long time), and a high-gloss black film layer with color change can be obtained (the materials of the black films are all PVC films, and there are differences in surface treatment). Through laser etching, a state of dark pattern and silver flowers can be achieved.
[0005] When an automobile film obtains dark pattern and silver flowers by laser etching, its depth determines the overall aesthetics and corresponding optical performance after the film is pasted. At present, the depth after etching of automobile films is mainly controlled by an etching machine. Affected by factors such as the parameter settings of the etching machine when etching the film and the state of the film being etched, the etching depth is prone to deviation, and it is difficult to determine the etching accuracy of the film surface. Summary of the Invention
[0006] To overcome the deficiencies of the prior art, an embodiment of the present application provides a black film etching depth measurement device.

This is conducive to using the first laser rangefinder as a reference to control the laser emitted by the laser emitter on the second laser rangefinder to sweep across the black film surface and enter the interior of the etching tank. It can achieve calculating the distance difference measured by the first laser rangefinder and the second laser rangefinder to determine the depth of the etching tank, facilitating the determination of the etching accuracy of the automotive black film and providing data support for subsequent use.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0027] Embodiment 1:
[0028] A black film etching depth measurement device, as Figures 1 - 5 shown, includes a first laser rangefinder 3 and a second laser rangefinder 9 disposed on one side of the first laser rangefinder 3 (the laser rangefinder ranging technology adopts the prior art, and it can select a KLM30 type laser rangefinder, a Deli rangefinder, etc. according to the actual situation, as well as high-precision laser rangefinders used in the conventional industrial field). The outside of the first laser rangefinder 3 is provided with a first support 4, two sliding rods 6 are machined on the surface of one side of the first support 4, and the outside of the second laser rangefinder 9 is provided with a second support 8;
[0029] Among them, the laser emitters of the first laser rangefinder 3 and the second laser rangefinder 9, as well as the laser receivers of the first laser rangefinder 3 and the second laser rangefinder 9 are all located in the same plane. An electric push rod 7 is hingedly connected between the first support 4 and the second support 8 (here, the control principle of the electric push rod 7 refers to the prior art, and the function exercised by the electric push rod 7 can be replaced by other means, such as a lead screw, manual, electromagnetic drive, etc.). When the electric push rod 7 works, both ends of the second support 8 are slidably connected to the outside of two slide rods 6, and the distance between the second support 8 and the first support 4 can be controlled, thereby controlling the distance between the first laser rangefinder 3 and the second laser rangefinder 9 (taking the first laser rangefinder 3 as the reference base point), and the laser emitted by the laser emitter on the second laser rangefinder 9 can be controlled to sweep across the black film surface 22 and shoot into the inside of the etching tank 23;
[0030] Secondly, in order to facilitate the fixation of the first laser rangefinder 3 to the first support 4 and the second laser rangefinder 9 to the second support 8, as Figures 1 to 3 shown, receiving grooves are processed on one side of the first support 4 and the second support 8, and limiting grooves 12 are processed on both inner walls of the receiving grooves. Limiting strips 11 are processed on the surfaces on both sides of the second support 8 and the first laser rangefinder 3. By making the limiting strips 11 and the limiting grooves 12 fit and connect, after inserting the second laser rangefinder 9 into the receiving groove on the second support 8 and inserting the first laser rangefinder 3 into the receiving groove on the first support 4, the second support 8 or the first laser rangefinder 3 can be fixed inside the receiving groove by means of the cooperation between the limiting strips 11 and the limiting grooves 12.
[0031] In a black film etching depth measuring device of the present utility model, by utilizing the cooperation between the limiting strips 11 and the limiting grooves 12, the first laser rangefinder 3 is fixed inside the first support 4, and the second laser rangefinder 9 is fixed inside the second support 8. When the electric push rod 7 controls the distance between the second support 8 and the first support 4, the second support 8 can slide on the outside of the slide rod 6, thereby adjusting the distance between the first laser rangefinder 3 and the second laser rangefinder 9 whose laser emitters and laser receivers are both located in the same plane. This is beneficial to controlling, with the first laser rangefinder 3 as the reference, the laser emitted by the laser emitter on the second laser rangefinder 9 to sweep across the black film surface 22 and shoot into the inside of the etching tank 23. By means of the distance difference measured by the first laser rangefinder 3 and the second laser rangefinder 9, the depth of the etching tank 23 is determined to ensure that the produced product is in a qualified state for use.
[0032] Embodiment 2:
[0033] On the basis of Embodiment 1, as Figure 1 、 Figure 4 and Figure 5As shown in the figure, this embodiment shows the specific structure of the first laser rangefinder 3. A vertical plate 14 is assembled and connected to the bottom of one side of the second support 8. A support shaft rod 17 is integrally formed at the center of the bottom of the vertical plate 14. An outer bearing 16 is in interference fit with the support shaft rod 17, and an outer control disk 10 is in interference fit with the bearing 16. A retaining disk 19 is arranged at the center of the bottom of the control disk 10;
[0034] Among them, by sleeving the retaining disk 19 on one end of the support shaft rod 17 and threading a bolt into the interior of one end of the support shaft rod 17, the retaining disk 19 is fixed to one end of the support shaft rod 17, and the bolt head can be used to prevent the control disk 10 from slipping off the outside of the support shaft rod 17 to the bottom;
[0035] Secondly, to ensure that the laser emitted by the laser emitter on the second laser rangefinder 9 can enter the interior of the etching grooves 23 with different widths, as Figure 4 shown, a plurality of second through holes 21 are machined on the edge of the control disk 10, and a plurality of first through holes 20 are machined at the center of the control disk 10. The diameters of the plurality of first through holes 20 are different and are arranged in decreasing order according to the diameter size;
[0036] Among them, the plurality of second through holes 21 are equally spaced around the center of the control disk 10, and the plurality of first through holes 20 are arranged around the center of the control disk 10. One second through hole 21 and one first through hole 20 are used in combination. When the first through holes 20 with different diameters are aligned with the laser emitter on the second laser rangefinder 9, the second through hole 21 is aligned with the laser receiver on the second laser rangefinder 9, so as to support the laser emitted by the second laser rangefinder 9 to pass through the interior of the first through hole 20, and after being reflected on the black film surface, it is received by the laser receiver from the interior of the second through hole 21.
[0037] In the black film etching depth measuring device of the present utility model, by controlling the control disk 10 to rotate around the support shaft rod 17 at the bottom of the second laser rangefinder 9, one second through hole 21 and one first through hole 20 used in combination are respectively aligned with the laser receiver and the laser emitter on the second laser rangefinder 9, so that the laser can pass through the interior of the first through hole 20, and after being reflected on the black film surface, it is received by the laser receiver from the interior of the second through hole 21. By aligning the first through holes 20 with different diameters with the laser emitter, the thickness of the laser light emitted from the interior of the first through hole 20 can be controlled, facilitating the laser emitted by the laser emitter on the second laser rangefinder 9 to enter the interior of the etching groove 23 according to the actual width of the etching groove 23 and performing distance detection work.

[0041] Secondly, in order to facilitate fixing the first support 4 to the top of the mounting base 102 to support the stable ranging of the first laser rangefinder 3 and the second laser rangefinder 9, as Figure 1 and Figure 3 shown, an installation notch 5 is processed inside one side of the first support 4. A spring bean 13 is connected in a receiving manner inside the installation notch 5. A plurality of positioning holes 2 are processed on the top of the mounting base 102. By making the bottom of the spring bean 13 extend out from the inside of the first support 4 and inserting it into the inside of a positioning hole 2, the first support 4 can be fixed to the outside of the mounting base 102 by the cooperation and limitation of the spring bean 13 and the positioning hole 2.
[0042] In a black film etching depth measuring device of the present utility model, a measuring bracket 1 is provided at the bottom of the first support 4, and a plurality of positioning holes 2 are processed on the top of the mounting base 102 of the measuring bracket 1. When the spring bean 13 inside the first support 4 cooperates with a positioning hole 2, the first support 4 can be fixed to the outside of the mounting base 102;
[0043] At the same time, by sliding the first support 4 outside the mounting base 102 and sliding the second support 8 outside the two sliding rods 6, the different areas of the surface of the automotive black film can be measured with the first laser rangefinder 3 as a reference point.
[0044] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description.
