Description

Technical Field

[0001] The present application relates to the field of laser processing. Specifically, it relates to a device for detecting whether there are missing holes after small holes are processed on the cylindrical surface of a pipe fitting. Background Art

[0002] Whether it is mechanical processing or laser processing, when mass-producing products with small holes on the cylindrical surface of pipe fittings, there will be a situation where the small holes on the cylindrical surface of the finished pipe are not processed. In the past, such detection errors were generally observed by someone or photographed with a camera for discrimination. Manual inspection is a repetitive and boring task. As the working time accumulates, people's visual perception will become fatigued, resulting in misjudgment. Although camera shooting can avoid people's visual perception fatigue in principle, due to factors such as the shooting focal length of the hardware for the material, the illumination of light, and the rotation delay of the cylinder, there will also be a certain error recognition rate.

[0003] In view of this, those skilled in the art need to develop a device for detecting missing holes in small holes of pipe fittings to address the above technical problems. Utility Model Content

[0004] The main purpose of the present application is to provide a device for detecting whether there are missing holes after small holes are processed on the cylindrical surface of a pipe fitting, realizing automatic detection of whether there are missing holes in the small holes on the pipe fitting, with high detection efficiency.

[0005] To achieve the above purpose, in a first aspect, the present application provides a device for detecting whether there are missing holes after small holes are processed on the cylindrical surface of a pipe fitting, including an inclined conveying component for conveying products, a wick shaft pushing component arranged on one side of the lowest end of the conveying component, and a photosensitive sleeve component arranged on the other side of the lowest end of the conveying component. The wick shaft pushing component includes an outer housing, a wick shaft slidably arranged in the outer housing, and a driving mechanism for driving the sliding of the wick shaft. The wick shaft is matched with the central hole of the product. The photosensitive sleeve component is provided with an insertion cavity matched with the product. The wick shaft is made of a transparent material, and a light-emitting unit is arranged inside the wick shaft.

[0006] Further improved, the photosensitive sleeve component is cylindrical, and the inner wall of the photosensitive sleeve component is curled by a flexible photosensitive material.

[0007] Further improved, the light-emitting unit is embedded in the wick shaft.

[0008] Further improved, the conveying component is a conveying plate, and baffles are respectively and fixedly arranged on both sides of the conveying plate.

[0009] Further improved, the driving mechanism is one of a push cylinder, an electric push rod, and a driving lead screw connected to the wick shaft.

[0010] Further improved, a positioning structure for positioning the product is provided at the lowest end of the conveying assembly.

[0011] Further improved, the positioning structure includes a positioning groove fixedly connected to the lowest end of the conveying assembly, and the positioning groove can only accommodate 1 said product.

[0012] Further improved, a limiting member is provided at the end of the wick shaft, and the size of the limiting member is larger than the size of the central hole of the product.

[0013] A device provided by the utility model for detecting whether there is a missing hole after a small hole is processed on the cylindrical surface of a pipe fitting. Compared with the prior art, its beneficial effect is that the wick shaft is pushed into the central hole of the product through the wick shaft pushing assembly, and then the product is pushed into the photosensitive sleeve assembly together. The light-emitting unit in the wick shaft emits a specific spectrum, and the light passes through the small hole of the product and irradiates on the photosensitive material on the inner wall of the photosensitive sleeve assembly to generate a photoelectric effect, transmitting a corresponding electrical signal. The electrical signal is compared with the electrical signal of the preset qualified product to check whether they are consistent. If they are not consistent, it indicates that there is a leakage hole phenomenon. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with embodiments to detail this application.

[0024] As Figure 1 - Figure 2 shown, a device for detecting whether there is a missing hole after a small hole is machined on the cylindrical surface of a pipe fitting includes an inclined conveying assembly for conveying products, a wick shaft pushing assembly arranged on one side of the lowest end of the conveying assembly, and a photosensitive sleeve assembly arranged on the other side of the lowest end of the conveying assembly. The wick shaft pushing assembly includes an outer housing, a wick shaft slidably arranged in the outer housing, and a driving mechanism for driving the wick shaft to slide. The wick shaft is matched with the central hole of the product. The photosensitive sleeve assembly is provided with an insertion cavity matched with the product. The wick shaft is made of a transparent material, and a light-emitting unit is arranged in the wick shaft. The photosensitive sleeve assembly is cylindrical, and the inner wall of the photosensitive sleeve assembly is curled by a flexible photosensitive material.

[0025] Working principle: The product slides down along the conveying component to the lowest end, and the wick shaft pushing component works to drive the sliding of the wick shaft, that is, it inserts into the inner hole of the pipe fitting, and then drives the pipe fitting to be inserted into the photosensitive sleeve component together. The wick shaft in the wick shaft pushing component is made of transparent material. When the light source of a specific spectrum embedded in it is turned on, the light will overflow through the small holes processed in the pipe fitting and irradiate on the inner cylindrical wall of the photosensitive sleeve component. This inner wall is curled by flexible photosensitive material. The overflowing light irradiates on it to generate the photoelectric effect and transmit the corresponding electrical signal. This signal is compared with the digital quantity of the electrical signal of the pre-set qualified product. If one signal is missing, it means that there is a situation where the small hole on this pipe fitting is not processed, and an alarm will be recorded and waiting for sorting.

[0026] The wick shaft can be made of materials such as glass and silica gel.

[0027] Preferably in this embodiment, the conveying component is a conveying plate, and baffles are fixedly arranged on both sides of the conveying plate. The product automatically slides down along the inclined conveying plate by its own gravity.

[0028] Preferably, the driving mechanism is one of a pushing cylinder, an electric push rod, and a driving lead screw connected to the wick shaft.

[0029] In order to facilitate the accurate insertion of the wick shaft into the inner control of the pipe fitting when it moves, a positioning structure for positioning the product is arranged at the lowest end of the conveying component. Specifically, the positioning structure includes a positioning groove fixedly connected to the lowest end of the conveying component, and the positioning groove can only accommodate 1 such product.

[0030] In order to drive the pipe fitting to move while the wick shaft inserts into the inner control of the pipe fitting, a limiting part is arranged at the end of the wick shaft, and the size of the limiting part is larger than the size of the central hole of the product.

[0031] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
