Figure 2 A structure exploded view of a nozzle detection device according to an embodiment of the present application. Reference is made to Figure 1 and Figure 2 An embodiment of the present application provides a nozzle detection device which can be applied to detect a nozzle 101 of a machining head 100, specifically to detect the coaxiality of the nozzle, the appearance of the nozzle, and the size of the nozzle.

[0049] Reference is made to Figure 1The processing head 100 includes a nozzle 101 and a processing head body 102. The nozzle 101 is arranged on the processing head body 102. The processing head body 102 is provided with a sensor (such as a capacitive sensor), and the nozzle 101 can be fixed to the sensor of the processing head body 102. Normally, the nozzle 101 should be coaxial with the sensor of the processing head body 102. The nozzle detection device provided by the embodiment of the application is used to detect the coaxiality of the nozzle 101 and the processing head body 102.

[0050] The processing head 100 can be a cutting head or a marking head. The aforementioned cutting head can be a laser cutting head, a flame cutting head, or a water cutting head. The aforementioned nozzle 101 can be a laser cutting nozzle, a flame cutting nozzle, or a water cutting nozzle.

[0051] Referring to Figure 1 and Figure 2 , the nozzle detection device provided by the embodiment of the application includes a mounting seat 1, a dustproof component 2, and a detection camera 3.

[0052] The mounting seat 1 is provided with a nozzle accommodating position 110 for accommodating the nozzle 101 of the processing head 100.

[0053] The dustproof component 2 is arranged on the mounting seat 1 and can move relative to the mounting seat 1 to cover or expose the nozzle accommodating position 110. Specifically, in the width direction W of the nozzle detection device, the dustproof component 2 can move left and right relative to the mounting seat 1.

[0054] The dustproof component 2 can be a plate-shaped structure or a block-shaped structure. The dustproof component 2 can be a transparent structure or a non-transparent structure.

[0055] The detection camera 3 is used to shoot an image of the nozzle to realize detection of the nozzle. The detection camera 3 is arranged inside the mounting seat 1.

[0056] In the height direction H of the nozzle detection device, the detection camera 3 is located below the nozzle accommodating position 110 to detect the nozzle 101 located in the nozzle accommodating position 110 below the nozzle accommodating position 110.

[0057] Figure 3 A working state diagram of the nozzle detection device provided by an embodiment of the application. Figure 4 Another working state diagram of the nozzle detection device provided by an embodiment of the application. Figure 5 Still another working state diagram of the nozzle detection device provided by an embodiment of the application. Referring to Figures 3 to 5 , the processing head 100 (such as a laser cutting head) is moved to above the height direction H of the nozzle detection device after replacing the nozzle 101 (such as automatically replacing the nozzle 101), so that the nozzle 101 is located directly above the nozzle accommodating position 110.Figure 4 , the dustproof component 2 moves relative to the mounting base 1, uncovers the nozzle accommodating position 110, and exposes the nozzle accommodating position 110. The machining head moves downward in the height direction H, and the nozzle 101 is located in the nozzle accommodating position 110. Referring to Figure 5 , at this time, the machining head body part 102 of the machining head covers the nozzle accommodating position 110. The detection camera 3 takes a photo of the nozzle and transmits the image to the computer system for processing to detect the coaxiality of the nozzle 101, to ensure that the center of the nozzle 101 and the machining head sensor are together, and to detect whether the appearance of the nozzle is damaged and whether the size meets the requirements.

[0058] After the detection is completed, the machining head moves upward in the height direction H, and the nozzle 101 is separated from the nozzle accommodating position 110. The dustproof component 2 moves relative to the mounting base 1 to cover the nozzle accommodating position 110.

[0059] According to the above, during the non-detection time, the dustproof component 2 covers the nozzle accommodating position 110; during the detection time, the dustproof component 2 moves relative to the mounting base 1 to uncover the nozzle accommodating position 110, so that the nozzle accommodating position 110 is exposed; the exposed nozzle accommodating position 110 accommodates the nozzle 101 of the machining head; the machining head covers the nozzle accommodating position 110; the detection camera 3 takes a photo of the nozzle for detection; the detection camera 3 can be protected from dust during both the non-detection time and the detection time, preventing dust generated by cutting from entering the interior of the mounting base 1 through the nozzle accommodating position 110 to contaminate the detection camera 3, improving the accuracy of detection, and improving the machining quality.

[0060] Referring to Figure 1 and Figure 2 , the nozzle detection device can further include a protective lens assembly 4.

[0061] The protective lens assembly 4 is a light-transmitting structure. The protective lens assembly 4 is located in the interior of the mounting base 1. Light can enter the interior of the mounting base from the nozzle accommodating position 110 and pass through the protective lens assembly 4 to be received by the detection camera 3 for photo detection.

[0062] Referring to Figure 1 and Figure 2 , in the height direction H, the protective lens assembly 4 is located above the detection camera 3 to protect the detection camera 3, prevent the detection camera 3 from being damaged, and prevent dust from contaminating the lens of the detection camera 3.

[0063] In the height direction H, the protective lens assembly 4 is located between the detection camera 3 and the dustproof component 2, so that the dustproof component 2 can prevent dust from entering the interior of the mounting base 1 to contaminate the lens of the protective lens assembly 4, and ensure the accuracy of detection.

[0075] The lens frame 411 and the lens cover plate 412 are both annular structures or hollow structures in the middle, to expose the protective lens 42, so that light can pass through the protective lens 42.

[0076] Referring to Figure 6The lens mounting component 41 can further include a lens gasket 413.

[0077] The lens gasket 413 is arranged on the lens frame 411.

[0078] The protective lens 42 is arranged on the lens gasket 413. The lens cover plate 412 fixes the lens gasket 413 and the protective lens 42 on the lens frame 411. The lens gasket 413 can provide cushioning for the protective lens 42 to prevent the protective lens 42 from being broken.

[0079] For example, the lens gasket 413 wraps the protective lens 42, and the lens cover plate 412 fixes the lens gasket 413 and the protective lens 42 on the lens frame 411, which can better protect the lens and facilitate replacement and cleaning of the lens.

[0083] In the height direction H, the aperture 5 is located above the detection camera 3. Light entering the inside of the mounting seat 1 from the nozzle accommodating position 110 can pass through the aperture 5 to reach the detection camera 3.

[0084] The detection camera 3 can automatically capture the nozzle 101 through the aperture 5, and can automatically detect the coaxiality of the nozzle and the center of the processing head sensor, detect whether the appearance of the nozzle 101 is damaged, and detect the size of the nozzle 101.

[0085] In the height direction H, the protective lens assembly 4, the aperture 5, and the detection camera 3 are arranged and fixed in sequence from top to bottom. The protective lens assembly 4 can protect the aperture 5 and the detection camera 3, prevent the aperture 5 and the detection camera 3 from being contaminated and affecting the detection accuracy, and achieve accurate shooting and detection of the nozzle 101.
