For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In addition, the terms "first", "second", "third", "fourth", "fifth", "sixth", and "seventh" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0035] It should be noted that the horizontal, longitudinal and vertical directions in the embodiments of the present invention are perpendicular to each other.

[0036] like Figure 1 As shown, an embodiment of the present invention provides a system for detecting the light type and air tightness of automobile headlights. The detection system includes a light type detection unit 1, an air tightness detection unit 2 and a machine tool 3. The light type detection unit 1 and the air tightness detection unit 2 are respectively arranged on both sides of the machine tool 3 in the horizontal direction.

[0037] like Figure 2 and Figure 3 As shown, the optical pattern detection unit 1 includes a first lower fixture 11, a first upper fixture 12, a first movable mechanism 13, a third movable mechanism 14, and a first detection chamber 15. The first lower fixture 11, the first upper fixture 12, and the third movable mechanism 14 are all located within the first detection chamber 15. The front of the first detection chamber 15 has a first opening communicating with the interior, allowing a worker to place the vehicle headlight to be inspected within the first detection chamber 15 through the first opening. Specifically, the first detection chamber 15 includes a first station and a second station along the longitudinal direction, with the first station being located near the first opening and the second station being located further away.

[0038] like Figure 4As shown, the first lower fixture 11 includes a first base 111 and a first base plate 112. The first base 111 is mounted on a third movable mechanism 14 via the first base plate 112, enabling the third movable mechanism 14 to drive the first base 111 toward or away from the first opening. The third movable mechanism 14 specifically includes a third drive device and a first longitudinal track 141 extending longitudinally. The first longitudinal track 141 is fixed to the machine tool 3. Driven by the third drive device, the first base 111 can reciprocate longitudinally between the first and second workstations.

[0039] Continue to refer Figure 3 and Figure 4 The first base 111 is a first contoured base. The inner contour of the upper portion of the first contoured base matches the outer contour of the front side of the automobile headlight, so that the automobile headlight can be placed on the upper portion of the first contoured base with the front side facing downward. It should be noted that the front side of the automobile headlight is the side that emits the light beam.

[0040] like Figure 6 As shown, the light pattern detection unit 1 also includes a dark box 16 and a camera detection device 17. The dark box 16 is located below the first profiling base, specifically below the second workstation. The camera detection device 17 is placed inside the dark box 16 to detect the light pattern of the vehicle headlight. When the vehicle headlight is placed on the first profiling base with its front side facing downward, the light beam emitted by the vehicle headlight can be illuminated by the dark box 16, allowing the camera detection device 17 inside the dark box 16 to detect the light pattern of the vehicle headlight.

[0041] It is understandable that, when the automobile headlights emit a light beam and illuminate the dark box 16 , the principle of detecting the light pattern of the automobile headlights by the camera detection device 17 is common knowledge in the art and will not be elaborated here.

[0042] like Figures 2 to 4 As shown, the first upper fixture 12 includes a first upper frame 121, a first clamping mechanism 122, a power plug 123, and a first drive device 124. The first clamping mechanism 122 and the first drive device 124 are respectively disposed on the first upper frame 121. The first clamping mechanism 122 is used to grasp the vehicle headlight, and the power plug 123 is disposed on the first upper frame 121 via the first drive device 124. The first moving mechanism 13 is connected to the first upper frame 121. The first moving mechanism 13 can drive the first clamping mechanism 122 to move via the first upper frame 121, so that the first clamping mechanism 122 approaches the first base 111. The first moving mechanism 13 can also drive the power plug 123 to move via the first upper frame 121 and the first drive device 124, so that the power plug 123 approaches the vehicle headlight on the first base 111.

[0043] like Figure 8As shown, the first moving mechanism 13 specifically includes a fourth drive device and a first vertical rail 131 extending vertically. The first upper frame 121 is slidably disposed on the first vertical rail 131. Driven by the fourth drive device, the first upper frame 121 can drive the first clamping mechanism 122 and the power plug 123 to reciprocate vertically, so that the first clamping mechanism 122 and the power plug 123 can move away from or closer to the first base 111.

[0044] Continue to refer Figure 4 The power plug 123 is used to electrically connect to the car headlight on the first base 111 to perform light pattern detection on the car headlight. The first driving device 124 is specifically a cylinder that can cause the power plug 123 to move back and forth vertically. When the power plug 123 is close to the car headlight on the first base 111, the first driving device 124 can drive the power plug 123 to be vertically inserted into the car headlight, thereby electrically connecting the power plug 123 to the car headlight.

[0045] like Figure 2 、 Figure 3 and Figure 7 As shown, the airtightness testing unit 2 includes a second lower fixture 21, a second upper fixture 22, a second movable mechanism 23, a fourth movable mechanism 24, and a second testing chamber 25. The second lower fixture 21, the second upper fixture 22, and the fourth movable mechanism 24 are all located within the second testing chamber 25. The front of the second testing chamber 25 has a second opening communicating with the interior, allowing workers to remove the tested vehicle headlights from the second testing chamber 25 through the second opening. Specifically, the second testing chamber 25 includes a third and fourth workstations in the longitudinal direction, with the third workstation located farther from the second opening and the fourth workstation located closer to the second opening.

[0046] like Figure 5 and Figure 7 As shown, the second lower fixture 21 includes a second base 211 and a second base plate 212. The second base 211 is mounted on a fourth movable mechanism 24 via the second base plate 212, enabling the fourth movable mechanism 24 to move the second base 211 toward or away from the second opening. The fourth movable mechanism 24 specifically includes a fifth drive device and a second longitudinal track 241 extending longitudinally. The second longitudinal track 241 is fixed to the machine tool 3. Driven by the fifth drive device, the second base 211 can reciprocate longitudinally between the third and fourth workstations.

[0047] Continue to refer Figure 3 and Figure 5 The second base 211 is a second contoured base, and the inner contour of the upper portion of the second contoured base matches the outer contour of the front side of the automobile headlight, so that the automobile headlight can be placed on the upper portion of the second contoured base with the front side facing downward.

[0048] like Figure 2 、 Figure 3 and Figure 5 As shown, the second upper fixture 22 includes a second upper frame 221, a second clamping mechanism 222, an inflation nozzle 223, and a second drive device 224. The second clamping mechanism 222 and the second drive device 224 are respectively disposed on the second upper frame 221. The second clamping mechanism 222 is used to grasp the automobile headlight, and the inflation nozzle 223 is disposed on the second upper frame 221 via the second drive device 224. The second moving mechanism 23 is connected to the second upper frame 221. The second moving mechanism 23 can drive the second clamping mechanism 222 to move via the second upper frame 221, so that the second clamping mechanism 222 approaches the second base 211. The second moving mechanism 23 can also drive the inflation nozzle 223 to move via the second upper frame 221 and the second drive device 224, so that the inflation nozzle 223 approaches the automobile headlight on the second base 211.

[0049] like Figure 8 As shown, the second moving mechanism 23 specifically includes a sixth drive device and a second vertical track 231 extending vertically. The second vertical track 231 is fixedly mounted on the machine tool 3, and the second upper frame 221 is slidably mounted on the second vertical track 231. Driven by the sixth drive device, the second upper frame 221 can drive the second clamping mechanism 222 and the inflation nozzle 223 to move back and forth vertically, so that the second clamping mechanism 222 and the inflation nozzle 223 can move away from or closer to the second base 211.

[0050] Continue to refer Figure 5 The inflation nozzle 223 is used to connect to the automobile headlight on the second base 211 to perform airtightness testing on the automobile headlight. The second driving device 224 is specifically a cylinder that can cause the inflation nozzle 223 to move back and forth vertically. When the inflation nozzle 223 is close to the automobile headlight on the second base 211, the second driving device 224 can drive the inflation nozzle 223 to be vertically inserted into the automobile headlight, thereby connecting the inflation nozzle 223 to the automobile headlight.

[0051] In addition, the airtightness testing unit 2 also includes an airtightness testing device, which is connected to the inflation nozzle 223 so that the airtightness testing device can perform airtightness testing on the automobile headlight when the inflation nozzle 223 is connected to the automobile headlight. The airtightness testing device is specifically an airtightness tester and can be located below the first inspection chamber 15 or the second inspection chamber 25.

[0052] It is understandable that, when the inflation nozzle 223 is connected to the automobile headlight, the principle of performing airtightness testing on the automobile headlight by using the airtightness testing device is common knowledge in the art and will not be elaborated here.

[0053] Continue to refer Figures 2 to 4 A third opening is provided between the second detection chamber 25 and the first detection chamber 15 so as to allow the two to communicate. The third opening is specifically located between the second station and the third station.

[0054] like Figure 8 As shown, the first moving mechanism 13 specifically includes a moving frame 133, a seventh drive device, and a transverse rail 132 extending laterally. The transverse rail 132 is fixedly mounted on the machine tool 3, the moving frame 133 slides on the transverse rail 132, and the fourth drive device and the first vertical rail 131 are fixedly mounted on the moving frame 133. Driven by the seventh drive device, the first clamping mechanism 122 is capable of reciprocating in the transverse direction. When the first clamping mechanism 122 is grasping the vehicle headlight, the first moving mechanism 13 can drive the first clamping mechanism 122 to move laterally from the second station through the third opening to the third station.

[0055] The control method of the embodiment of the utility model comprises the following steps:

[0056] It should be noted that in the initial state of the detection system, the first lower jig 11 is located at the first station, the first upper jig 12 is located at the second station, the second lower jig 21 is located at the third station, and the second upper jig 22 is located at the fourth station.

[0057] Step S1 : The detection system is in an initial state; a car headlight to be detected is placed on the first base 111 .

[0058] Step S2 : the third moving mechanism 14 drives the first base 111 to move from the first station to the second station, so that the car headlight is located below the first upper fixture 12 and above the dark box 16 .

[0059] Specifically, driven by the third driving device, the first base 111 drives the automobile headlight to move along the first longitudinal track 141 from the first workstation to the second workstation.

[0060] Step S3 : the first moving mechanism 13 drives the first clamping mechanism 122 and the power plug 123 to approach the car headlight on the first base 111 .

[0061] Specifically, driven by the fourth driving device, the first upper frame 121 drives the first clamping mechanism 122 and the power plug 123 along the first vertical track 131 to approach the car headlight on the first base 111.

[0062] Step S4: the first driving device 124 drives the power plug 123 to be plugged into the automobile headlight in a vertical direction, thereby electrically connecting the power plug 123 to the automobile headlight and performing light pattern detection.

[0063] Step S5: After the light pattern detection is completed, the first driving device 124 drives the power plug 123 to move vertically away from the first base 111, so that the power plug 123 is separated from the automobile headlight.

[0064] Step S6 : the first clamping mechanism 122 grabs the car headlight on the first base 111 and transfers it to the second base 211 through the first moving mechanism 13 .

[0065] Specifically, after the first clamping mechanism 122 grasps the car headlight on the first base 111, the first upper frame 121, driven by the fourth drive device, drives the first clamping mechanism 122 along the first vertical track 131 away from the first base 111. Then, driven by the seventh drive device, the first clamping mechanism 122 moves the car headlight along the transverse track 132 to above the second base 211. Thereafter, driven by the fourth drive device, the first upper frame 121 drives the first clamping mechanism 122, which is grasping the car headlight, along the first vertical track 131 toward the second base 211 and places the car headlight on the second base 211. After completing the above actions, the first upper jig 12 returns to the second workstation.

[0066] In step S7 , the fourth moving mechanism 24 drives the second base 211 to move from the third station to the fourth station, so that the car headlight is located below the second upper fixture 22 .

[0067] Specifically, driven by the fifth driving device, the second base 211 drives the automobile headlight to move along the second longitudinal track 241 from the third station to the fourth station.

[0068] Step S8 : the second moving mechanism 23 drives the second clamping mechanism 222 and the inflation nozzle 223 to approach the car headlight on the second base 211 .

[0069] Specifically, driven by the sixth driving device, the second upper frame 221 drives the second clamping mechanism 222 and the inflation nozzle 223 along the second vertical track 231 to approach the car headlight on the second base 211 .

[0070] Step S9: the second driving device 224 drives the inflation nozzle 223 to be plugged into the automobile headlight in a vertical direction, thereby connecting the inflation nozzle 223 to the automobile headlight, and performing an airtightness test.

[0071] Step S10: After the airtightness test is completed, the second driving device 224 drives the inflation nozzle 223 to move vertically away from the second base 211, so that the inflation nozzle 223 is separated from the automobile headlight.

[0072] Step S11: The second clamping mechanism 222 grabs the inspected automobile headlight on the second base 211 so that the staff can unload it.

[0073] Specifically, after the second clamping mechanism 222 grabs the inspected car headlight on the second base 211, under the drive of the sixth driving device, the second upper frame 221 drives the second clamping mechanism 222 along the second vertical track 231 away from the second base 211 to grab the inspected car headlight, thereby making it convenient for the staff to remove the car headlight from the second clamping mechanism 222 from the second opening.

[0074] When the above-mentioned technical solution is adopted, the embodiment of the utility model can automatically perform light type detection and air tightness detection on automobile headlights in sequence, reducing the operation steps of manually transferring automobile headlights, thereby shortening the detection time of the entire process, improving detection efficiency, and improving the degree of automation of the detection system.

However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
