[0023] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] In this embodiment:

[0025] Reference Figure 1 The diagram shows a preferred embodiment of the present invention.

[0026] This embodiment of an automatic PCB drilling tool breakage analysis device includes: a body 1, which is detachably mounted on a drilling device via a mounting bracket 3 and screws; a laser emitter 2, which is mounted on the body 1 and corresponds to the tool position, for emitting and receiving laser light; and a dustproof device 4, which is detachably mounted on the body 1, wherein the dustproof device 4 encloses the laser emitter 2 and intercepts external dust, preventing dust from adhering to the laser emitter 2.

[0027] Figure 2 , Figure 3 and Figure 4The dustproof device 4 shown includes: a screw 42, which is fixed to the machine body 1 via an annular seat 41, wherein the annular seat 41 encloses the laser emitting head 2; a protective cover 43, which is fitted onto the screw 42 and secured by a nut, wherein the protective cover 43 encloses the laser emitting head 2; and a circular tube 44, which is fixed to the protective cover 43, wherein the inner wall of the circular tube 44 has multiple perforations 45, and the laser emitted by the laser emitting head 2 is emitted from inside the circular tube 44. By setting up the dustproof device 4, the protective cover 43 is first manually moved to move the circular tube 44. When the protective cover 43 moves to the position fitted onto the screw 42, the screw is rotated using a tool. The nut moves up and down along the surface of the screw 42 and presses and fixes the protective cover 43, so that the protective cover 43 encloses the laser emitter 2, allowing the laser to be emitted from inside the round tube 44. The protective cover 43, together with the round tube 44, intercepts external debris and dust, while debris and dust falling into the round tube 44 are discharged through multiple holes 45, thereby achieving dust protection for the laser emitter 2. This reduces the amount of floating debris and dust adhering to the laser emitter 2, which could form a barrier layer on the surface of the laser emitter 2 and hinder the normal irradiation of the laser, affecting the accuracy of broken blade analysis. This improves the cleanliness of the surface of the laser emitter 2 and the safety of use.

[0028] Figure 2 , Figure 3 and Figure 4 The dustproof device 4 also includes a cover plate 46, which is rotatably mounted on the side of the circular tube 44 away from the protective cover 43. The cover plate 46 is fixed in place by a protrusion engaging with a groove during rotation. By providing the cover plate 46, when the laser emitter 2 is not in use, the cover plate 46 can be rotated to completely cover the circular tube 44, preventing external dust and impurities from entering the interior of the circular tube 44 and accumulating. The dustproof device 4 also includes an electric telescopic rod 47, which is fixedly connected to the protective cover. 43; scraper ring 48, wherein the scraper ring 48 is fixedly connected to the output end of the electric telescopic rod 47, wherein the scraper ring 48 is placed inside the round tube 44 and slides against its inner wall. By setting the scraper ring 48, the electric telescopic rod 47 is first started, so that the electric telescopic rod 47 drives the scraper to move along the inside of the round tube 44 away from the protective cover 43, so that the scraper ring 48, during the movement, adheres to the inner wall of the round tube 44 and pushes out the residual debris and dust from the round tube 44, thereby achieving rapid cleaning of the debris and dust accumulated inside the round tube 44.

[0029] Figure 2 , Figure 3 and Figure 4A scraper 413 is fixedly connected to one side of the scraper ring 48 shown. The cross-section of the scraper 413 is triangular. By setting the scraper 413, the scraper 413 can assist the scraper ring 48 in scraping up the strongly adhering debris or dust, further improving the cleaning effect of the scraper ring 48. The dustproof device 4 also includes: an arc plate 49, which is fixed to the cover 43. The arc plate 49 is placed on the side of the round tube 44 near the drain hole 45; and a collection box 410, which is placed on the arc plate 49 and is used to collect and store the debris and dust discharged from the drain hole 45. The collection box 410 is made of iron. By setting the collection box 410, the collection box 410 is first placed on the arc plate 49, so that the collection box 410 is positioned below the drain hole 45, so that the debris and dust discharged through the drain hole 45 and the inside of the round tube 44 fall into the collection box 410 for storage, which facilitates the quick cleaning of debris and dust by personnel later.

[0030] Figure 2 , Figure 3 and Figure 4 A magnet 412 is fixedly connected to the side of the protective cover 43 near the arc plate 49. The magnet 412 is fixed to the collection box 410 by adsorption. By setting the magnet 412, the collection box 410 can be adsorbed and fixed, reducing the possibility of the collection box 410 slipping on the arc plate 49. A blocking plate 411 is fixedly connected to the side of the collection box 410 away from the protective cover 43. The blocking plate 411 is inclined away from the circular tube 44. By setting the blocking plate 411, the debris and dust pushed out by the scraper ring 48 can be intercepted and guided into the collection box 410 for storage, thereby improving the collection efficiency of debris and dust.

[0031] Working principle: First, the broken tool detector (model TRS2) on the machine body 1 is fixedly installed inside the drilling machine using the mounting bracket 3 and screws, so that the laser emitter 2 on the machine body 1 corresponds to the position of the tool. Then, the laser emitter 2 projects a beam of light onto the rotating tool and receives the reflected light signal. The internal system of the machine body 1 then analyzes the spectral characteristics of the reflected light to distinguish between the intact and damaged states of the tool, quickly determine the integrity of the tool, and thus achieve the analysis of broken tools.

[0032] First, manually move the protective cover 43 to move the circular tube 44. When the protective cover 43 moves to the position where it is fitted onto the screw 42, rotate the nut with a tool to move the nut up and down along the surface of the screw 42 and press and fix the protective cover 43, so that the protective cover 43 encloses the laser emitter 2, allowing the laser to be emitted from inside the circular tube 44. The protective cover 43, together with the circular tube 44, intercepts external debris and dust, reducing the exposed area of ​​the laser emitter 2. At the same time, the debris and dust falling into the circular tube 44 are discharged through multiple holes 45 and stored in the collection box 410 below, thereby achieving dust protection for the laser emitter 2.

[0033] When a lot of debris and dust accumulate inside the round tube 44, the electric telescopic rod 47 is activated, which drives the scraper to move along the inside of the round tube 44 away from the protective cover 43. As the scraper ring 48 moves, it adheres to the inner wall of the round tube 44 and pushes out the remaining debris and dust from the round tube 44, which then falls into the collection box 410 below for storage, thereby achieving rapid cleaning of the debris and dust accumulated inside the round tube 44.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
