[0028] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0029] The first implementation method:

[0030] Figure 1-Figure 5 The invention shows an infrared anti-reflection film performance detection device, which includes an infrared laser 101, an infrared detector 102, and a film placement and adjustment component. The film placement and adjustment component includes a film placement cylinder 201. A detection through hole 202 is opened in the middle of the top of the film placement cylinder 201. A blocking plug 203 is provided in the detection through hole 202 and is slidably and sealedly connected to the blocking plug 203. The top of the blocking plug 203 is flush with the top of the film placement cylinder 201. The bottom of the blocking plug 203 is fixedly connected to a linkage plate 204. A push-pull cylinder 214 is fixedly installed on the inner wall of the bottom end of the sheet placing cylinder 201, and an air squeezing plate 206 is provided above the push-pull cylinder 214 and is slidably and sealedly connected to the sheet placing cylinder 201. A connecting rod 205 is fixedly connected between the output end of the push-pull cylinder 214 and the bottom end of the linkage plate 204. The connecting rod 205 passes through the air squeezing plate 206 and is slidably connected thereto. A pair of elastic suspension ropes 207 are fixedly connected between the air squeezing plate 206 and the inner wall of the top end of the sheet placing cylinder 201;

[0031] A horizontal container cylinder 208 is embedded through the side wall of the sheet placing cylinder 201, and the horizontal container cylinder 208 is located above the air squeezing plate 206, and one end of the horizontal container cylinder 208 located in the sheet placing cylinder 201 is set to an open shape, and the bottom end of the horizontal container cylinder 208 is connected to an air guide pipe 209, and the end of the air guide pipe 209 away from the horizontal container cylinder 208 is located below the air squeezing plate 206 and is connected to the interior of the sheet placing cylinder 201, and a guide push plate 210 is provided in the horizontal container cylinder 208 and is connected to the horizontal container cylinder 208 with a sliding sealing connection therewith. The side of the guide push plate 210 away from the air guide pipe 209 is fixedly connected to a support plate 211, and the infrared detector 102 is fixedly mounted on the support plate 211, and the infrared detector 102 is located directly above the detection through hole 202.

[0032] During the inspection, the infrared anti-reflection film to be inspected is placed flat on the top of the film placement cylinder 201. Since the top of the blocking plug 203 is flush with the top of the film placement cylinder 201, the top of the film placement cylinder 201 can be regarded as a flat plane, so that the infrared anti-reflection film is easy to place flatly. The push-pull cylinder 214 is controlled to drive the blocking plug 203 and the linkage plate 204 to move downward until the infrared detector 102 moves to the bottom of the detection through hole 202. When the push-pull cylinder 214 drives the blocking plug 203 and the linkage plate 204 to move downward, the linkage plate 204 and the extrusion plate 206 are abutted, and the push-pull cylinder 214 continues to drive the blocking plug 203 and the linkage plate 204 to move downward. At this time, the extrusion plate 206 06 will move downward with the linkage plate 204, and because the linkage plate 204 and the connecting rod 205 are against each other, the connection between the connecting rod 205 and the extrusion plate 206 can be sealed, so that when the extrusion plate 206 moves downward with the linkage plate 204, the extrusion plate 206 will squeeze the air below it, and the squeezed air will flow into the horizontal container cylinder 208 through the air guide pipe 209. The inflow of air will push the guide plate 210, causing the support plate 211 and the infrared detector 102 to move out of the horizontal container cylinder 208. Therefore, by controlling the push-pull cylinder 214 to drive the push-pull cylinder 214 to move the blocking plug 203 and the linkage plate 204 downward, the infrared detector 102 can be moved to just below the detection through hole 202;

[0033] After the infrared detector 102 moves to the position just below the detection through hole 202, the infrared laser 101 and the infrared detector 102 are started, so that the infrared laser 101 emits infrared light of a specific wavelength to the infrared detector 102 (the wavelength of the infrared light emitted by the infrared laser 101 is set by a person skilled in the art as appropriate). The infrared detector 102 receives the infrared light after passing through the infrared anti-reflection film, measures the intensity of the transmitted light, and then can measure the intensity of the incident light according to the incident light intensity (the incident light intensity refers to the intensity of the incident light when the infrared laser 101 emits infrared light of a specific wavelength directly to the infrared detector 102 under the same conditions without placing the infrared anti-reflection film). The light, corresponding to the light intensity measured by the infrared detector 102, the measurement of the incident light intensity is a prior art and will not be elaborated here) and the transmitted light intensity are used to calculate the transmittance of the infrared anti-reflection film, and then complete the detection; therefore, through the setting of the piece placement and adjustment component, when the infrared anti-reflection film is detected, the infrared anti-reflection film is easy to place flat, and after the infrared anti-reflection film is placed, the piece placement and adjustment component will be adjusted accordingly, so that during the detection, there are no obstructions between the infrared laser 101 and the infrared anti-reflection film, and between the infrared anti-reflection film and the infrared detector 102, thereby greatly improving the accuracy of the detection.

[0034] See also Figure 2-Figure 3An elastic pull rope 212 is fixedly connected between the guide push plate 210 and the inner wall of the horizontal container cylinder 208. The elastic pull rope 212 is located on the side of the guide push plate 210 away from the support plate 211, which is conducive to the automatic reset of the guide push plate 210, the support plate 211, the elastic pull rope 212, etc. A ventilation pipe 213 is connected to the side wall of the film placement cylinder 201. The ventilation pipe 213 is located above the extrusion plate 206 to avoid the formation of negative pressure above the extrusion plate 206 when the extrusion plate 206 moves downward, causing deformation of the infrared anti-reflection film.

[0035] See also Figure 1 、 Figure 4 and Figure 5 A support frame 103 is fixedly installed on the outer wall of the film placement cylinder 201, and a lifting cylinder 104 is fixedly installed on the support frame 103. The outer cover of the infrared laser 101 is provided with a sensor sample cylinder 003, which is located below the lifting cylinder 104 and fixedly connected to the output end of the lifting cylinder 104. The sensor sample cylinder 003 is composed of a sensor connecting cylinder 301 and an elastic sample ring 302 matching the sensor connecting cylinder 301. The bottom end of the sensor connecting cylinder 301 is set to an open shape. The elastic sample ring 302 is made of elastic sealing material and is fixedly installed on the bottom end of the sensor connecting cylinder 301. The infrared laser 101 is fixedly connected to the top inner wall of the sensor connecting cylinder 301.

[0036] During detection, after the infrared anti-reflection film is placed flat, before controlling the push-pull cylinder 214 to drive the blocking plug 203 and the linkage plate 204 to move downward, first control the lifting cylinder 104 to drive the container sample cylinder 003 to move downward until the elastic sample ring 302 is against the infrared anti-reflection film, thereby fixing the infrared anti-reflection film, which not only prevents the infrared anti-reflection film from being deformed when the blocking plug 203 moves downward, but also prevents the infrared anti-reflection film from moving during the movement, and the container sample cylinder 003 can also play a shading role to prevent the light in the environment from affecting the detection results; therefore, through the arrangement of the support frame 103, the lifting cylinder 104, the container sample cylinder 003, etc., the infrared anti-reflection film can be fixed after it is placed flat to prevent the infrared anti-reflection film from being deformed and moving, and at the same time, the influence of ambient light on the detection can be eliminated, thereby further improving the accuracy of the detection.

[0037] Second implementation method:

[0038] Figure 6-Figure 9The present invention shows an infrared anti-reflection film performance detection device. Different from the first embodiment, the detection device also includes a flattening detection patch assembly arranged on the sample receiving cylinder 003 of the sensor. The flattening detection patch assembly includes an outer cover tube 401 fixedly mounted on the outer wall of the sensor connecting cylinder 301. The bottom end of the outer cover tube 401 is set to an open shape. The outer walls on the left and right sides of the outer cover tube 401 are respectively embedded with an exhaust pipe 402 and an inflation pipe 403. The end of the exhaust pipe 402 located on the inner side of the outer cover tube 401 is connected to the interior of the sensor connecting cylinder 301, and the exhaust pipe 403 is connected to the inner wall of the sensor connecting cylinder 301. 02 is provided with a solenoid valve 404, and an inflation one-way valve 405 is provided at one end of the inflation tube 403 located on the inner side of the outer cover tube 401, and the other end of the inflation tube 403 is connected to the air pump. The flattening inspection assembly also includes an air pressure sensor 406 fixedly installed in the outer cover tube 401. The inner diameter of the outer cover tube 401 matches the outer diameter of the sheet placing cylinder 201. When the outer cover tube 401 is sleeved on the sheet placing cylinder 201, the outer cover tube 401 can be slidably and sealedly connected to the sheet placing cylinder 201, and the bottom end of the outer cover tube 401 is lower than the bottom end of the elastic sample ring 302.

[0039] The detection device also includes a pressure detection intelligent controller 005 fixedly mounted on the outer wall of the sheet placing cylinder 201. The pressure detection intelligent controller 005 is provided with a pressure detection setting module, a pressure detection control module, a detection analysis module, a ring reminder module, and a control button. The pressure detection setting module and the control button are all connected to the pressure detection control module by signal. The pressure detection control module is connected to the lifting cylinder 104, the solenoid valve 404, the air pressure sensor 406, and the air pump by signal. The air pressure sensor 406 is connected to the detection analysis module by signal. The detection analysis module is connected to the ring reminder module by signal.

[0040] During the inspection, after the infrared anti-reflection film is placed flat, before controlling the push-pull cylinder 214 to drive the blocking plug 203 and the linkage plate 204 to move downward, the pressure inspection command can be issued to the pressure inspection control module through the control button. After receiving the command, the pressure inspection control module will control the lifting cylinder 104 to drive the container sample cylinder 003 to move downward. Since the outer cover tube 401 is mounted on the container sample cylinder 003, the outer cover tube 401 will move downward with the container sample cylinder 003. What is different from the first embodiment is that in this embodiment, when the pressure inspection control module controls the lifting cylinder 104 to drive the container sample cylinder 003 to move downward, it will not directly cause the elastic sample ring to move downward. 302 is not against the infrared anti-reflection film, but after the outer cover tube 401 is sleeved on the film placement cylinder 201, the lifting cylinder 104 will temporarily stop driving the container sample cylinder 003 to move downward (the downward movement distance can be set by those skilled in the art through the pressure detection setting module according to the thickness of the infrared anti-reflection film), so that the elastic sample ring 302 is suspended above the infrared anti-reflection film, and then the pressure detection control module will start the air pump to fill a certain amount of air into the inner side of the outer cover tube 401 and the inner side of the container sample cylinder 003 through the air pump, the inflation tube 403, and the inflation one-way valve 405 (the amount of air filled can be set by the pressure detection setting module as needed);

[0041] The filling of air will cause the air pressure in the outer cover tube 401 to increase, so that under the action of air pressure, the infrared anti-reflection film will be closely attached to the top of the film-setting tube 201, so that the infrared anti-reflection film can be further leveled, making the infrared anti-reflection film flatter. After the inflation is completed, the pressure detection control module will turn off the air pump and control the lifting cylinder 104 to continue to drive the sample container cylinder 003 to move downward until the elastic sample ring 302 is against the infrared anti-reflection film. Then, the pressure detection control module will open the solenoid valve 404 and start the air pressure sensor 406. After the solenoid valve 404 is opened, The pressure inside the sample container cylinder 003 can be relieved through the exhaust pipe 402 to restore the air pressure inside the sample container cylinder 003 to normal, thereby preventing the infrared anti-reflection film at the detection hole 202 from being concave and deformed downward under the action of air pressure when the subsequent blocking plug 203 moves downward. After the air pressure sensor 406 is activated, it will monitor the air pressure inside the outer cover cylinder 401, and the air pressure data monitored by the air pressure sensor 406 will be transmitted to the inspection and analysis module in real time, so that the inspection and analysis module can determine whether there is any abnormality by analyzing the air pressure data monitored by the air pressure sensor 406.

[0042] After the solenoid valve 404 is activated, the air inside the sample cylinder 003 of the sensor can be discharged to the outside of the outer cover cylinder 401 through the exhaust pipe 402, but the air inside the outer cover cylinder 401 cannot be discharged to the outside through the exhaust pipe 402. Therefore, under normal circumstances, the air pressure inside the outer cover cylinder 401 will remain unchanged. However, if the elastic sample ring 302 fails to contact the infrared anti-reflection film, or the elastic sample ring 302 contacts the infrared anti-reflection film but the elastic sample ring 302 fails to fit tightly with the infrared anti-reflection film due to the unevenness of the infrared anti-reflection film (the elastic sample ring 302 If the infrared anti-reflection film is not offset, it will affect the fixing effect of the infrared anti-reflection film, and thus indirectly affect the detection results. The unevenness of the infrared anti-reflection film will directly affect the detection results. Therefore, the above two situations are abnormal situations). Then the air inside the outer cover tube 401 will leak into the inner side of the receiving sample cylinder 003 through the connection between the elastic sample ring 302 and the infrared anti-reflection film, which will cause the air pressure inside the outer cover tube 401 to gradually decrease. Therefore, the inspection and analysis module can determine whether there is an abnormality by analyzing the air pressure data monitored by the air pressure sensor 406;

[0043] When the judgment result is that there is an abnormality, the inspection and analysis module will control the ringing reminder module to sound an alarm to remind the relevant technical personnel, prompting the relevant technical personnel to stop the inspection and perform corresponding maintenance. When the judgment result is that there is no abnormality, the inspection and analysis module will control the ringing reminder module to emit a prompt sound representing normal. After hearing the prompt sound representing normal, the push-pull cylinder 214 can be controlled to drive the push-pull cylinder 214 to drive the blocking plug 203 and the linkage plate 204 to move downward, and perform subsequent inspection operations; therefore, through the settings of the flattening inspection component, the pressure inspection intelligent controller 005, etc., when the infrared anti-reflection film is inspected, the infrared anti-reflection film can be flattened by air pressure to make the infrared anti-reflection film flatter, and it will also automatically check and judge whether there is an abnormality. When there is an abnormality, an alarm will be sounded to remind the relevant technical personnel, thereby further improving the accuracy of the inspection.

[0044] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
