[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the present invention is not limited to the following embodiments.

[0025] Embodiment 1:

[0026] See attached Figures 1 to 4. An automatic bottle knocking crack detection device comprises a supporting mechanism, an adjusting mechanism, a bottle knocking mechanism and a sound recognition system; the supporting mechanism is connected to the adjusting mechanism; the adjusting mechanism is connected to the bottle knocking mechanism; the sound recognition system is used to recognize the sound made by the bottle knocking mechanism knocking the bottle; the adjusting mechanism is used to adjust the direction of the bottle knocking mechanism. As can be seen from the above structure, the automatic bottle knocking crack detection device of the utility model can automatically knock on the detected bottle and collect the sound for comparative analysis, so as to screen out the detected bottles with crack defects quickly and efficiently. Specifically, the supporting mechanism is used to support the adjustment mechanism and the bottle knocking mechanism, etc., which includes a base 13 and a supporting seat 14. The base 13 is in contact with the ground, and the supporting seat 14 is connected to the base 13 through a connecting plate to form a supporting frame. The adjusting mechanism is fixedly connected above the supporting frame. The adjusting mechanism specifically includes a connecting seat 8. Both ends of the connecting seat 8 are provided with a first arc-shaped connecting plate 9. The two first arc-shaped connecting plates 9 are connected to the second arc-shaped connecting plates 10 through bearings. The first arc-shaped connecting plates 9 and the second arc-shaped connecting plates 10 are symmetrically arranged. A slide rail seat 3 is fixed between the two second arc-shaped connecting plates 10. The bearing structure between the first arc-shaped connecting plate 9 and the second arc-shaped connecting plate 10 ensures that the second arc-shaped connecting plate 10 can rotate with the bearing as the axis, and the two second arc-shaped connecting plates 10 are synchronously arranged. The slide rail seat 3 is provided with a bottle knocking mechanism. The two second arc-shaped connecting plates 10 can drive the slide rail seat 3 and the bottle knocking mechanism to rotate within a certain angle range, so that the bottle knocking mechanism can perform bottle knocking detection at different positions. The bottle knocking mechanism mainly consists of a power mechanism and a bottle knocking rod. The power mechanism is a telescopic cylinder 2, which is fixed to one end of a slide rail seat 3. The output end of the telescopic cylinder 2 is fixedly connected with a slider 4, which is matched and connected with the slide rail seat 3 and can slide on the slide rail seat 3. The telescopic cylinder 2 makes a reciprocating motion on the slide rail seat 3 by controlling the slider 4. The other end of the slider 4 is connected to the middle section of the knocking rod 1 through a connecting rod. One end of the knocking rod 1 is hinged on the second arc-shaped connecting plate 10, so that a partial structure of the knocking rod 1 forms a triangular structure with the connecting rod and the second arc-shaped connecting plate 10, such as Figures 1 to 4As shown, the telescopic movement of the telescopic cylinder 2 drives the connecting rod to drive the knocking rod 1 to rotate around the hinge, forming a knocking movement process, and realizing the knocking detection of the detected bottle. The sound recognition system uses a built-in algorithm and records the knocking sound of qualified bottles without cracks in advance. Then, during the detection process, the knocking rod 1 emits sounds of different frequencies to the detected bottle, and then collects and compares them with the sounds of the built-in qualified bottles, and analyzes whether there are other defects. The built-in algorithm and sound recognition system here all use existing technologies, and their principles will not be further explained. Finally, a signal is sent to the external system, and the external system performs subsequent work by analyzing the signal, such as automatically screening defective products. The automatic bottle knocking crack detection equipment of the utility model can effectively solve the problems of high labor intensity, easy fatigue and low efficiency of traditional manual bottle knocking in the prior art, and cannot meet the requirements of production speed-up, digitalization and intelligence of production.
