Description

Technical Field

[0002] In the process of modern automobile manufacturing, as an important safety component, the quality of headlights is directly related to driving safety. In order to ensure the quality of headlights, vision inspection technology is usually used in the production process to check various defects and performance indicators of headlights. However, cracks and bubbles are often small in size. The existing vision inspection technology for headlight production uses a single camera to take pictures for identification, and only relies on the single-camera image to detect and identify headlight inspection parts, such as defects like bubbles and cracks on the headlight cover. The efficiency is low and the accuracy is poor. In addition, single-camera photo identification may fail to identify defects due to the lack of some features of the headlight, resulting in incorrect detection results. Therefore, there is an urgent need for a vision inspection mechanism for headlight production that can quickly detect minute defects of headlights and the absence of headlight shapes.

[0015] Advantages of the present invention:

[0016] 1. By setting the first traction wire and the lamp beads, the first traction wire pulls the outer clamping assembly to limit the vehicle lamp detection piece, and the sliding lamp holder is located at the edge bottom of the vehicle lamp detection piece. By starting the lamp beads, the lamp beads illuminate the edge bottom of the vehicle lamp detection piece. When the vehicle lamp detection piece is a vehicle lamp cover, the light emitted by the lamp beads will be refracted and reflected multiple times inside the vehicle lamp detection piece, and refraction and diffuse reflection will occur on the irradiated surfaces of the bubbles and cracks, forming bright spots that are easier to observe, facilitating the detection of bubbles and cracks in the vehicle lamp detection piece, improving the detection efficiency of bubbles and cracks in the vehicle lamp detection piece, and the detection quality of bubbles and cracks in the vehicle lamp detection piece; when the vehicle lamp detection piece is a vehicle lamp housing or the whole vehicle lamp, the light emitted by the lamp beads irradiates the side bottom of the vehicle lamp detection piece, making the diffuse reflection brightness of the side bottom of the vehicle lamp detection piece higher than other parts of itself, thereby strengthening the bottom contour characteristics of the vehicle lamp detection piece and facilitating the subsequent detection of shape defects of the vehicle lamp detection piece;

[0017] 2. The present invention sets two cameras with different angles and adjustable orientations. By enabling the cameras, after the lamp beads are enabled, the cameras capture the shape features of the vehicle lamp detection component. Among them, the two cameras cooperate with each other to simultaneously collect images of the vehicle lamp detection component, thereby forming a stereo vision detection, more accurately obtaining the three-dimensional dimensions and shape information of the vehicle lamp detection component, and more efficiently detecting cracks and bubbles in the vehicle lamp.

[0018] 3. The present invention sets a resin plate. When the camera rotates to the topmost position, the camera faces the resin plate, and power is supplied to the vehicle lamp detection component as the overall vehicle lamp, causing the vehicle lamp detection component to light up. The light of the vehicle lamp detection component will irradiate on the resin plate, causing the light of the vehicle lamp detection component to scatter at the fine bubbles inside the resin plate, thereby forming the Tyndall effect. The light path of the vehicle lamp detection component is visualized and displayed inside the resin plate. The camera detects the light distribution and uniformity of the light of the vehicle lamp detection component by photographing the light path inside the resin plate, effectively improving the detection efficiency of the light of the vehicle lamp detection component.

Embodiment

[0031] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but it is not intended to limit the present invention.

[0032] Example 1

[0033] A vision inspection mechanism for headlight production, as Figures 1-4 shown, includes a base 1. The outer circumferential wall of the base 1 is fixedly connected with first support frames 2 in mirror image distribution. It also includes a support slide bar 3. The support slide bar 3 is fixedly connected to one of the first support frames 2. A lighting clamping unit 4 is installed on the support slide bar 3. The lighting clamping unit 4 is used to clamp the headlight inspection piece and illuminate the bubbles, cracks and contour features of the headlight inspection piece;

[0034] The lighting clamping unit 4 includes a lifting plate 401 which is slidably connected to the support slide bar 3 in a penetrating manner. The bottom of the lifting plate 401 contacts the base 1, and both sides of the lifting plate 401 are in sliding contact with the first support frame 2. A support housing 402 is fixedly connected to the center of the bottom of the lifting plate 401. A first wire spool 406 is circumferentially distributed and rotatably connected inside the support housing 402. Linear chutes are circumferentially distributed on the lifting plate 401, and a plum blossom rod 407 is fixedly connected between the lifting plate 401 and the support housing 402. An outer clamping assembly 408 and an inner clamping assembly 409 are arranged on the plum blossom rod 407. A first elastic washer 412, a sliding lamp holder 413, and a second elastic washer 414 are slidably connected to the plum blossom rod 407. The outer clamping assembly 408, the inner clamping assembly 409, and the sliding lamp holder 413 all slide inside the linear chutes of the lifting plate 401. One side of the outer clamping assembly 408 is connected to the first elastic washer 412, and the first elastic washer 412 is fixedly connected to the sliding lamp holder 413 on one side. A lamp bead 415 is fixedly installed on the top of the sliding lamp holder 413, and the top of the lamp bead 415 is lower than the top surface of the lifting plate 401 to prevent the lamp bead 415 from colliding with the vehicle lamp detection component. One side of the sliding lamp holder 413 is fixedly connected to the second elastic washer 414. A guide ring 410 is arranged at the bottom of the outer clamping assembly 408, and a first traction wire 411 is wound around the guide ring 410. One end of the first traction wire 411 penetrates the support housing 402 and is fixedly connected to the first wire spool 406, and the other end of the first traction wire 411 is connected to the inner clamping assembly 409. When the first wire spool 406 is pulled, the traction direction of the inner clamping assembly 409 can be changed through the guide ring 410, so that the outer clamping assembly 408 and the inner clamping assembly 409 move closer. A driving component is installed at the bottom of the support housing 402, and the driving component is connected to the first wire spool 406 through a damping rod. By driving the first wire spool 406 to rotate, the position of the lamp bead 415 is adjusted by the outer clamping assembly 408.

[0035] First, the staff places the vehicle headlight detection part on the lifting plate 401, with the detected surface of the vehicle headlight detection part facing upward for easy observation of the vehicle headlight detection part. Subsequently, the staff activates the driving component to rotate the first wire spool 406, so that the circumferential outer wall of the first wire spool 406 winds up and retracts the first traction wire 411. The retraction of the first traction wire 411 shortens the length of the first traction wire 411 located outside the support housing 402, thereby generating a pulling force to guide the guide ring 410. The guide ring 410 is pulled and drives the outer clamping component 408 to slide on the plum blossom rod 407. At the same time, the pulling force of the first traction wire 411 will pull the inner clamping component 409 to slide on the plum blossom rod 407, so that the inner clamping component 409 and the outer clamping component 408 approach each other. During the movement of the outer clamping component 408, it will push the first elastic washer 412 to move synchronously. When the first elastic washer 412 moves, it will drive the sliding lamp holder 413 to move synchronously, so that the sliding lamp holder 413 drives the second elastic washer 414 and the lamp bead 415 to move synchronously. When the outer clamping component 408 contacts the vehicle headlight detection part, the vehicle headlight detection part is clamped and limited by the outer clamping component 408. At this time, the outer clamping component 408 is limited by the vehicle headlight detection part and cannot move. The length of the first traction wire 411 located outside the support housing 402 continues to shorten, causing the first traction wire 411 to pull the inner clamping component 409 to continue approaching the outer clamping component 408. During the movement of the inner clamping component 409, it will squeeze the second elastic washer 414. While the second elastic washer 414 is deformed under extrusion, it will drive the sliding lamp holder 413 to move and squeeze the first elastic washer 412, so that the first elastic washer 412 and the second elastic washer 414 are deformed to the same extent synchronously, so that the sliding lamp holder 413 is always located exactly in the middle of the outer clamping component 408 and the inner clamping component 409. At this time, the sliding lamp holder 413 is located at the edge bottom of the vehicle headlight detection part. The staff activates the lamp bead 415, and the lamp bead 415 illuminates the edge bottom of the vehicle headlight detection part. When the vehicle headlight detection part is the lamp shade part of the vehicle headlight, the light emitted by the lamp bead 415 irradiates the side bottom of the vehicle headlight detection part, causing part of the light to be refracted and reflected multiple times inside the vehicle headlight detection part. During the reflection of the light inside the vehicle headlight detection part, it will irradiate on the cracks and bubbles of the vehicle headlight detection part, and refraction and diffuse reflection will occur on the irradiated surfaces of the bubbles and cracks, so that the light is diffusely reflected through the bubbles and cracks and transmitted through the vehicle headlight detection part to the outside world, forming a bright spot that is easier to observe, facilitating the detection of bubbles and cracks in the vehicle headlight detection part, improving the detection efficiency of bubbles and cracks in the vehicle headlight detection part, and the detection quality of bubbles and cracks in the vehicle headlight detection part; when the vehicle headlight detection part is the vehicle headlight housing or the whole vehicle headlight, the light emitted by the lamp bead 415 irradiates the side bottom of the vehicle headlight detection part, making the diffuse reflection brightness of the side bottom of the vehicle headlight detection part higher than other parts of itself, thereby strengthening the bottom contour feature of the vehicle headlight detection part, facilitating the subsequent detection of shape defects of the vehicle headlight detection part.

[0036] Such as Figure 4As shown, the outer clamping assembly 408 includes a first slider 4081. The first slider 4081 slides in the linear chute of the lifting plate 401. The first slider 4081 is slidably connected through the plum blossom rod 407. A guiding frustum 4082 is detachably fixed to the top of the first slider 4081, which is used to laterally squeeze and fix the vehicle lamp detection part. The circular table surface of the guiding frustum 4082 faces downward, facilitating the guiding frustum 4082 to laterally squeeze the vehicle lamp detection part while moving closer to each other, and at the same time, downwardly squeezing the vehicle lamp detection part, so that the bottom of the vehicle lamp detection part is in extrusion fit with the lifting plate 401, thereby preventing the vehicle lamp detection part from moving up and down along its inclined surface after being squeezed. The detachable connection method of the guiding frustum 4082 enables the guiding frustum 4082 to replace the corresponding height and the slope of the circular table surface according to the size of the vehicle lamp detection part. The bottom of the first slider 4081 is fixedly connected to the guiding ring 410, and a first tension spring 4083 is fixedly connected between the bottom of the first slider 4081 and the lifting plate 401. One side of the first slider 4081 is fixedly connected to the first elastic washer 412.

[0037] During the movement of the outer clamping assembly 408, that is, during the process that the first traction wire 411 pulls the first slider 4081 to slide on the plum blossom rod 407 through the guiding ring 410, the first slider 4081 will stretch the first tension spring 4083 and drive the guiding frustum 4082 to move synchronously, so that the guiding frustum 4082 contacts the vehicle lamp detection part, and the vehicle lamp detection part is downwardly squeezed under the guidance of the inclined surface of the guiding frustum 4082, thereby tightly fitting the vehicle lamp detection part on the lifting plate 401, so as to stably fix the vehicle lamp detection part.

[0038] As Figure 4 shown, the inner clamping assembly 409 includes a second slider 4091. The second slider 4091 is slidably connected through the plum blossom rod 407. The second slider 4091 slides in the linear chute of the lifting plate 401. A clamping block 4092 is fixedly connected to the top of the second slider 4091. The clamping block 4092 is semi-flat spherical. When the bottom surface of the vehicle lamp detection part is an arc surface, the semi-flat spherical structure of the clamping block 4092 can prevent the vehicle lamp detection part from moving upward when squeezing the vehicle lamp detection part. A third tension spring 4093 is connected between one side of the second slider 4091 and the support housing 402.

[0039] During the movement of the inner clamping assembly 409, that is, during the process that the first traction wire 411 pulls the second slider 4091 to slide on the plum blossom rod 407, the movement of the second slider 4091 will stretch the third tension spring 4093 and drive the top clamping block 4092 to move synchronously, so that the top arc surface of the clamping block 4092 squeezes the vehicle lamp detection part, thereby cooperating with the inclined surface of the guiding frustum 4082 to further clamp the vehicle lamp detection part, preventing the special-shaped vehicle lamp detection part from being squeezed by the top arc surface of the clamping block 4092 and causing the vehicle lamp detection part to move due to extrusion.

[0040] AsFigures 2-3 As shown in the figure, the driving component includes a first motor 403. The first motor 403 is installed at the bottom of the support housing 402. The output shaft of the first motor 403 is fixedly connected with a first gear 404. A plurality of second gears 405 are rotatably connected in the support housing 402. The second gears 405 are frictionally clamped with the first wire shaft 406 through damping rods, so that the first wire shaft 406 can rotate idly when encountering a large torque, preventing the first wire shaft 406 from being twisted and broken.

[0041] The staff starts the first motor 403, so that the output shaft of the first motor 403 rotates to drive the first gear 404 to rotate. The rotation of the first gear 404 drives the second gear 405 meshing with it to rotate in the reverse direction. The rotation of the second gear 405 drives the first wire shaft 406 to rotate synchronously through the damping rod, thereby performing the above-mentioned clamping process on the vehicle lamp detection part. Since the vehicle lamp detection part often has an irregular shape, the lengths that several first traction wires 411 can shorten outside the support housing 402 are often different, so that the rotation angles of the first wire shaft 406 can be different. When the first wire shaft 406 reaches the limit of the rotation angle, the second gear 405 drives the damping rod to rotate idly, thus avoiding the first wire shaft 406 from being twisted and broken.

[0042] Embodiment 2

[0043] On the basis of Embodiment 1, as Figure 1 and Figures 5-8 shown, it further includes a horizontal adjustment unit 5. The horizontal adjustment unit 5 includes an annular guide rail 501. Two first support frames 2 are fixedly connected with the annular guide rail 501 together. The top of the annular guide rail 501 is rotatably connected with an annular frame 502. The top of the annular frame 502 is provided with a first arc-shaped chute. The first arc-shaped chute is semi-circular. Two first sliding frames 503 are slidably connected in the first arc-shaped chute in a mirror image distribution. One side of the top of the two first sliding frames 503 is rotatably connected with a rotating frame 504. Cameras 505 are fixedly installed on the tops of the two rotating frames 504. The cameras 505 have a heat source capture function, which is convenient for the cameras 505 to perform high-temperature detection and heat dissipation detection on the vehicle lamp detection part. A vertical adjustment unit 6 is installed at the bottom of the rotating frame 504. The vertical adjustment unit 6 is used to adjust the vertical angle of the camera 505 through the rotating frame 504, so that the center of the lifting plate 401 is always within the shooting range of the camera 505.

[0044] After the positioning of the vehicle headlight is completed, the staff activates the camera 505. Since the center of the lifting plate 401 is always within the shooting range of the camera 505, the vehicle headlight detection component above the lifting plate 401 is also always within the shooting range of the camera 505. After the lamp beads 415 are activated, the camera 505 captures the shape characteristics of the vehicle headlight detection component. Among them, the two cameras 505 cooperate with each other and simultaneously collect images of the vehicle headlight detection component at different positions and in different directions, thus forming a stereo vision detection. Compared with the existing single-camera vision detection, it can more accurately obtain the three-dimensional size and shape information of the vehicle headlight detection component, and thus more efficiently detect cracks, bubbles and shape defects of the vehicle headlight detection component.

[0045] As Figures 5-6 shown, the horizontal adjustment unit 5 further includes a second motor 506. The second motor 506 is fixedly installed on one side of another first support frame 2. The output end of the second motor 506 is fixedly connected with a rotating shaft 507. The rotating shaft 507 penetrates through the other first support frame 2 and is rotatably connected with the other first support frame 2. One end of the rotating shaft 507 is fixedly connected with a bevel gear 508. A bevel gear ring 509 is fixedly connected to the circumferential outer wall of the annular frame 502. The bevel gear 508 meshes with the bevel gear ring 509, enabling the second motor 506 to drive the annular frame 502 to rotate through the bevel gear 508 and the bevel gear ring 509, and further enabling the two cameras 505 to rotate synchronously.

[0046] During the process of the staff activating the camera 505, the second motor 506 can be started. The rotation of the output shaft of the second motor 506 drives the bevel gear 508 to rotate through the rotating shaft 507, so that the bevel gear 508 drives the bevel gear ring 509 meshing with it to rotate. The rotation of the bevel gear ring 509 will drive the annular frame 502 to rotate on the annular guide rail 501, so that the annular frame 502 drives the first sliding frame 503 to rotate synchronously. The rotation of the first sliding frame 503 will drive the camera 505 to rotate synchronously through the rotating frame 504, enabling the camera 505 to capture the vehicle headlight detection component from different horizontal angles, thereby improving the detection efficiency and detection effect of the vehicle headlight detection component.

[0047] As Figures 7-9 shown, the horizontal adjustment unit 5 further includes a third motor 510. The third motor 510 is fixedly installed on the top of the annular frame 502. The output end of the third motor 510 is fixedly connected with a second wire spool 511. The second wire spool 511 is rotatably connected with the annular frame 502, and a second traction wire 512 is fixedly connected to the second wire spool 511. The second traction wire 512 penetrates through the annular frame 502 and one of the first sliding frames 503, and is fixedly connected with the other first sliding frame 503 along the first arc-shaped chute of the annular frame 502. A cylindrical spring 513 is sleeved outside the second traction wire 512. The cylindrical spring 513 restricts the movement range of the second traction wire 512, and both ends of the cylindrical spring 513 are fixedly connected with the first sliding frame 503.

[0048] During the process of the staff activating the camera 505, the third motor 510 can be started. The output shaft of the third motor 510 rotates to drive the second spool 511 to rotate, so that the second spool 511 winds the second towing line 512. The length of the second towing line 512 located in the first arc-shaped chute of the annular frame 502 is shortened, thereby causing the second towing line 512 to pull one of the first sliding frames 503, enabling the first sliding frame 503 to slide in the first arc-shaped chute of the annular frame 502 and compress the cylindrical spring 513. The first sliding frame 503 drives the camera 505 to rotate synchronously through the rotating frame 504. When the output shaft of the third motor 510 rotates in the reverse direction, the output shaft of the third motor 510 rotates in the reverse direction to drive the second spool 511 to rotate synchronously, causing the second towing line 512 to release the second spool 511. One of the first sliding frames 503 loses the pulling force of the second spool 511, enabling the cylindrical spring 513 to release and push one of the first sliding frames 503 to slide in the reverse direction in the first arc-shaped chute of the annular frame 502. The first sliding frame 503 drives the camera 505 to rotate synchronously through the rotating frame 504, thereby adjusting the angle between the two cameras 505 and achieving multi-angle stereoscopic vision detection, improving the detection efficiency of the vehicle lamp detection component.

[0049] As Figure 1 and Figures 5-8 shown, the vertical adjustment unit 6 includes a fourth motor 601. The fourth motor 601 is fixedly installed inside the other first support frame 2. The output shaft of the fourth motor 601 penetrates through the other first support frame 2 and is fixedly connected to a variable pitch screw 602. There are two threads with different pitches on the circumferential outer wall of the variable pitch screw 602. The thread with a smaller pitch is located at the top of the variable pitch screw 602, and the thread with a larger pitch is located at the bottom of the variable pitch screw 602. The bottom of the variable pitch screw 602 is threadedly connected to the lifting plate 401, and the top of the variable pitch screw 602 is threadedly connected to a second support frame 603. A third support frame 604 is slidably connected to the support slide rod 3. The second support frame 603 and the third support frame 604 are jointly fixedly connected to a rotating ring 605. One side of the rotating ring 605 is fixedly connected to an arc-shaped guide rail 606. A second arc-shaped chute is opened on one side of the arc-shaped guide rail 606. The angular range of the second arc-shaped chute corresponds to the first arc-shaped chute of the annular frame 502. Second sliding frames 607 are slidably connected in a mirror image distribution in the second arc-shaped chute. Third arc-shaped chutes are opened in a mirror image distribution on the rotating frame 504, and the second sliding frames 607 slide in the third arc-shaped chutes.

[0050] During the process of the staff enabling the camera 505, the fourth motor 601 can be started. The output shaft of the fourth motor 601 drives the pitch-changing screw 602 to rotate. The rotation of the pitch-changing screw 602 drives the lifting plate 401 to move upward, so that the lifting plate 401 drives the vehicle lamp detection component to move upward. Moreover, the rotation of the pitch-changing screw 602 drives the second support frame 603 to move upward, so that the second support frame 603 drives the rotating ring 605 to move upward synchronously. The upward movement of the rotating ring 605 makes the third support frame 604 slide upward along the support slide rod 3, and drives the second sliding frame 607 to move upward through the arc-shaped guide rail 606. The second sliding frame 607 squeezes the third arc-shaped chute of the rotating frame 504, and the second sliding frame 607 drives the rotating frame 504 to rotate upward, so that the rotating frame 504 drives the camera 505 to rotate synchronously. Thus, the vehicle lamp detection component is always included in the shooting range of the camera 505, and the camera 505 can shoot the vehicle lamp detection component from different vertical angles, thereby improving the detection efficiency and detection accuracy of the vehicle lamp detection component.

[0051] Embodiment 3

[0052] On the basis of Embodiment 2, as Figure 1 and Figure 5 shown, it further includes a fourth support frame 7. The top of the annular frame 502 is fixedly connected with the fourth support frame 7. A resin plate 8 is fixedly connected inside the fourth support frame 7. The bottom of the resin plate 8 is lower than the circumferential inner wall of the fourth support frame 7, which is convenient for the camera 505 to observe the circumferential outer wall of the resin plate 8. The resin plate 8 is filled with fine air bubbles, so that the light path is shown when the light passes through the resin plate 8.

[0053] When the vehicle lamp detection component is the whole vehicle lamp, and when the camera 505 rotates to the topmost position, the camera 505 faces the resin plate 8. At this time, the lifting plate 401 drives the vehicle lamp detection component to approach the resin plate 8. At this time, the external power supply is connected to the vehicle lamp detection component through a wire, so that the vehicle lamp detection component is lit by the external power supply. The light of the vehicle lamp detection component will irradiate on the resin plate 8, and the light of the vehicle lamp detection component will scatter at the fine air bubbles in the resin plate 8, thereby forming the Tyndall effect. The light path of the vehicle lamp detection component is visualized and shown in the resin plate 8. The camera 505 detects the light distribution and uniformity of the light of the vehicle lamp detection component by shooting the light path in the resin plate 8, effectively improving the detection efficiency of the light of the vehicle lamp detection component.

[0054] Embodiment 4

[0055] On the basis of Embodiment 2, as Figure 1 and Figures 10-11As shown, it further includes a hot air cleaning unit 9. The hot air cleaning unit 9 includes a flexible support frame 901. The flexible support frames 901 are fixedly connected to the outer circumferential wall of the base 1 in a mirror image distribution. One end of the flexible support frame 901 is fixedly connected to a venturi tube 902. One end of the venturi tube 902 is connected and installed with a heating tube 903 for heating the air flowing through the venturi tube 902. The other end of the venturi tube 902 is fixedly connected to an external gas cylinder with a pressure valve through a first hose in a connected manner. The bottom of the venturi tube 902 is fixedly connected to a U-shaped tube 904 in a connected manner. Water is contained in the U-shaped tube 904, and the water surface is lower than the inner top surface of the U-shaped tube 904. One end of the U-shaped tube 904 is fixedly connected to a piston cylinder 905, and a one-way valve 906 is installed at the other end of the U-shaped tube 904. Liquid through holes are provided on the piston cylinder 905 in a mirror image distribution. A liquid guide piston 907 is slidably connected in the piston cylinder 905. A diversion groove is provided at the center of the circumferential outer wall of the liquid guide piston 907. The diversion groove is L-shaped, so that the diversion groove can adjust the communication state with the liquid through holes to prevent the water in the U-shaped tube 904 from leaking. A fourth tension spring 908 is connected between the liquid guide piston 907 and the piston cylinder 905. A three-way pressure relief valve 909 is installed on the outer wall of the U-shaped tube 904 in a connected manner. The water inlet end of the three-way pressure relief valve 909 is connected to a water pump through a second hose, the water outlet end communicates with the inside of the U-shaped tube 904, and the pressure relief end communicates with an external water tank through a third hose.

[0056] When the staff fixes the headlight detection part above the lifting plate 401, the heating tube 903 can be started, and at the same time, the external air pressure valve is started, so that the compressed gas in the gas cylinder flows to form an air flow. The air flow enters the venturi tube 902 through the first hose. When the air flow enters the small-diameter part of the venturi tube 902 from the large-diameter part at one end of the venturi tube 902, based on Bernoulli's principle, the air flow velocity increases and the air pressure becomes smaller. The decrease in air pressure causes the air flow to drive the liquid guide piston 907 to move upward through the pressure difference. The upward movement of the liquid guide piston 907 stretches the fourth tension spring 908 and makes the diversion groove of the liquid guide piston 907 communicate with the diversion hole of the piston cylinder 905. The water in the U-shaped tube 904 flows toward the piston cylinder 905 under the guidance of the low pressure of the air flow, thereby forming a high and low liquid level difference in the U-shaped tube 904. The external gas enters the U-shaped tube 904 through the one-way valve 906. The water in the U-shaped tube 904 enters the diversion hole of the piston cylinder 905 as the liquid level rises and enters the venturi tube 902 through the diversion groove of the liquid guide piston 907. The high-speed flowing air flow breaks up and atomizes the water, so that the air flow is filled with water mist. The air flow absorbs heat and is heated after passing through the heating tube 903 and is sprayed on the headlight detection part. The water mist in the air flow cleans the surface of the headlight detection part, and the air flow conducts a high-temperature resistance test on the headlight detection part. Through the heat source capture function of the camera 505, the temperature of the headlight detection part is monitored, so as to judge the high-temperature resistance ability of the headlight detection part. When the liquid level at the lower part in the U-shaped tube 904 drops to the inner bottom surface of the U-shaped tube 904, the air at one end in the U-shaped tube 904 can enter the other end of the U-shaped tube 904 through the bottom of the U-shaped tube 904, so that the air enters the diversion hole of the piston cylinder 905 and enters the venturi tube 902 through the diversion groove of the liquid guide piston 907. At this time, the air flow no longer contains water mist, so that the surface of the headlight detection part will be quickly dried when the air flow is ejected, avoiding interference with the bubble, crack and optical path detection of the headlight detection part.

[0057] After the hot air flow is ejected, the staff closes the heating tube 903 and the external air pressure valve, so that the venturi tube 902 stops working, and the inside of the venturi tube 902 no longer maintains a low pressure, so that the fourth tension spring 908 pulls the liquid guide piston 907 to reset, and the diversion groove of the liquid guide piston 907 is disconnected from the diversion hole of the piston cylinder 905. When it is necessary to replenish water to the U-shaped tube 904, the staff starts the external water pump, so that the water enters the three-way pressure relief valve 909 through the second hose. The three-way pressure relief valve 909 passes the water into the U-shaped tube 904. The circumferential outer wall of the liquid guide piston 907 blocks the water from flowing out from the diversion hole of the piston cylinder 905, so that the water pressure in the U-shaped tube 904 increases. When the water pressure in the U-shaped tube 904 reaches the threshold value of the three-way pressure relief valve 909, the end of the three-way pressure relief valve 909 leading to the U-shaped tube 904 will be closed, so that the water flows out through the pressure relief of the three-way pressure relief valve 909 and flows into the external water tank through the third hose, preventing the U-shaped tube 904 from bursting due to excessive water added to the U-shaped tube 904.

Accordingly, the scope of the present invention should be limited only by the appended claims.
