Description

Technical Field

[0001] The invention relates to the field of egg and poultry detection, in particular to a vertical vibration detection device for egg cracks. Background Art

[0002] As a high-nutrition, high-consumption animal food, the integrity of the eggshell has an important impact on its quality and safety during production, processing and transportation. Cracks in the eggshell will not only reduce the market value of eggs, but also lead to the invasion of microorganisms and cause food safety problems. Therefore, the development of efficient egg crack detection technology is of great significance to improving egg quality and protecting consumer health.

[0003] At present, the detection methods of cracks in poultry eggs mainly include machine vision detection and acoustic characteristics detection. Although machine vision detection has advantages in identifying indicators such as eggshell surface shape, color, and blood spots, its detection ability for tiny cracks is limited, and it is easily affected by stains on the eggshell surface, resulting in a high misjudgment rate. In addition, the image acquisition method of machine vision detection is difficult to achieve continuous coverage of the entire surface of the eggshell, which limits its application in online detection.

[0004] The acoustic characteristic detection method, also known as audio detection technology, is to knock on the eggs and collect the generated audio signals, analyze their characteristic parameters, and use the discrimination model to identify whether there are cracks in the eggshell. Compared with machine vision detection, acoustic detection technology has higher detection efficiency and accuracy, and is not affected by stains on the eggshell surface. Foreign countries have put into commercial application the egg crack detection technology and equipment based on acoustic characteristics. Its main process includes knocking excitation, audio signal collection, characteristic parameter extraction and crack discrimination.

[0005] However, most of the existing acoustic detection technologies are to place duck eggs on a conveying mechanism and roll them, and then knock on the duck eggs while rolling. However, the size, direction and position of the knocking force need to be precisely controlled during the knocking process. If the knocking force is too small, it may not generate enough vibration signals to identify cracks, resulting in a decrease in the signal-to-noise ratio and affecting the accuracy of the detection results. On the contrary, if the knocking force is too large, it may cause nonlinear response or signal distortion in the structure, which will also affect the reliability of the detection results. Moreover, in the process of repeated knocking, it is difficult to ensure that the strength, direction and position of each knock are completely consistent. This inconsistency may cause fluctuations and errors in the detection results, affecting the stability and reliability of the detection. Summary of the invention

[0006] The purpose of the present invention is to provide a vertical vibration detection device for egg cracks, which effectively solves the problem that it is difficult to ensure that the force, direction and position of each knock are completely consistent compared to the existing rolling knocking method.

[0054] Preferably, there are multiple egg-laying poultry vibration detection components 3, and a data acquisition card 5, a computer 6 and a voltage-stabilized power supply 7 are provided outside the egg-laying poultry vibration detection component 3.

When the eggs are placed vertically on the annular egg tray 3-1, the distance between them and the top of the microphone on the microphone collecting plate 3-2 is 10-20 mm. Four fixing holes are left on the outermost side of the base 3-5, which is fixed to a fixing plate by screws. Each unit on the fixing plate corresponds to the operating position of the suction cup 4-3-1.

[0061] Preferably, the power transmission assembly 4 includes a driving device 4-1, a translational swing arm device 4-2 and an adsorption device 4-3, and the driving device 4-1 includes a reducer 4-1-1, a motor 4-1-2 and a coupling 4-1-3, and optionally a 130 servo motor 4-1-2 and a two-stage planetary reducer 4-1-1 with a reduction ratio of 1 to 35.

[0062] A connecting plate 8 with an L-shaped cross section is provided on the top of the base plate 1, the reducer 4-1-1 is fixed on the connecting plate 8, the motor 4-1-2 is connected to the end of the reducer 4-1-1 away from the connection, the other end of the reducer 4-1-1 is connected to the coupling 4-1-3, and the other end of the coupling 4-1-3 is connected to the translational swing arm device 4-2.

There are two wheel seats 4-2-2 and they are connected to the top of the base plate 1. The pulley 4-2-3 is fixed to the wheel seat 4-2-2 by screws. The swing arm main shaft 4-2-1 is passed through the two pulleys 4-2-3, and an annular brass sleeve 9 is provided between the pulleys 4-2-3. A key groove 10 is provided on the side wall of one end of the swing arm main shaft 4-2-1 close to the coupling 4-1-3, and the swing arm main shaft 4-2-1 and the coupling 4-1-3 are connected together.

[0064] Preferably, swing arm connecting rods 11 are symmetrically arranged on the swing arm main shaft 4-2-1, and the two swing arm connecting rods 11 are located between the opposite surfaces of the two pulleys 4-2-3. Positioning keys 12 are symmetrically arranged on the outer wall of the swing arm main shaft 4-2-1, and the positioning keys 12 are connected between the swing arm connecting rods 11 and the swing arm main shaft 4-2-1. The other ends of the two swing arm connecting rods 11 are equipped with seat bearings 13, and the seat bearings 13 are provided with the same pulley 4-2-3. The synchronous belt 4-2-4 is connected between the upper and lower pulleys 4-2-3 on the same side of the swing arm connecting rod 11. A follower shaft 14 passing through the pulley 4-2-3 is arranged between the tops of the two swing arms, and the same positioning keys 12 are arranged on the outer wall of the follower shaft 14 and between the seat bearings 13. A spacer sleeve 15 is installed at the end of the follower shaft 14. The pulley 4-2-3 can be selected with a tension sleeve model and is installed next to the spacer sleeve 15 to keep a certain distance from the swing arm connecting rod 11.

[0065] It should be noted that after the suction bracket 4-3-2 is fixed on the follower shaft 14 by means of the support 1 4-3-3 and the support 2 4-3-4, the motor 4-1-2 is started, and the reducer 4-1-1 drives the swing arm main shaft 4-2-1 to rotate through the coupling 4-1-3. The swing arm main shaft 4-2-1 is connected with a pulley 4-2-3 and a swing arm connecting rod 11, thereby driving the swing arm connecting rod 11 to rotate. Under the linkage of the synchronous belt 4-2-4, the suction bracket 4-3-2 is rotated, and the suction bracket 4-3-2 is always kept in a horizontal state.

[0066] Preferably, the adsorption device 4-3 includes a suction cup 4-3-1, a suction frame 4-3-2, a support 1 4-3-3 and a support 2 4-3-4. The suction frame 4-3-2 is placed horizontally and is always parallel to the axis of the follower shaft 14. There are multiple suction cups 4-3-1. The suction cups 4-3-1 are connected to the side of the suction frame 4-3-2 close to the substrate 1 through a locking member 16 and the suction port is set downward. The top of the suction frame 4-3-2 is symmetrically connected to the support 1 4-3-3 through a pad 17. The support 1 4-3-3 and the support 2 4-3-4 cooperate with each other.

An air pipe support pipe 20 is installed on the air pipe guide shaft support 19. The air pipe support pipe 20 is connected to the air distribution plate to divide one air source into twelve routes.

[0068] It should be noted that the translational swing arm device 4-2 follows the driving transposition rotation. As long as the initial state of the adsorption device 4-3 is kept horizontal, when the swing arm main shaft 4-2-1 produces any angular displacement during operation, the adsorption device 4-3 always produces an angular displacement of the same size and opposite direction, so that the adsorption device 4-3 and the egg placing plate 2 remain parallel during movement, thereby maintaining horizontal alignment with the duck eggs.

[0069] The suction cup 4-3-1 is a three-layer vacuum corrugated suction cup 4-3-1 with a suction diameter of 35 mm and a height of 47 mm. The material is silica gel, which ensures that every poultry egg can be adsorbed.

[0070] The egg placing plate 2 is placed on the work station, the control system sends a signal, and the translational swing arm device 4-2 approaches the top of the duck eggs. At this time, negative pressure is introduced into the adsorption device 4-3, and as the swing arm connecting rod 11 moves, it gradually contacts the duck eggs and absorbs the duck eggs through negative pressure. When the swing arm connecting rod 11 rotates to the detection table, the vacuum environment of the suction cup 4-3-1 disappears quickly, and the duck eggs fall into individual egg-laying poultry vibration detection components 3 respectively. Then the swing arm connecting rod 11 is reset, waiting for the next egg placing plate 2 to enter the work station.

[0071] Among them, Figure 7 As shown, the microphone acquisition board 3-2 is used to collect the acoustic signal generated in the resonance. The electret microphone used is omnidirectional φ9.7*4.5mm 1.5V-10V, with a sensitivity of -38db. The step-down chip 78L05 is used to reduce 12V to 5V. The signal conditioning circuit amplifies and filters the signal collected by the microphone. The rail-to-rail dual-channel power amplifier chip AD8552 is used. The signal amplification part is a co-directional amplifier circuit with an amplification factor of 11. The hardware filtering part is a second-order Butterworth filter with a cut-off frequency of 10KHz.

[0072] like Figure 8 As shown, the vibration drive board 3-4 uses an integrated power amplifier chip NS4110B, and a 1KΩ@100MHz magnetic bead and a 1nf capacitor are used at the output end to form a filter to remove high-frequency noise. The input end connects a resistor and a capacitor in series to form a high-pass filter with a cut-off frequency of 53Hz.

[0073] Detailed usage and effects of the above embodiments:

[0074] In the present invention, duck eggs are selected for poultry egg detection, but as long as they belong to poultry eggs, they are within the protection scope of the present invention. The detection of duck eggs includes two parts: offline analysis and online detection. The online detection process refers to that the computer 6 sends a 1-4KHz sweep frequency signal, and at the same time enables the data acquisition card 5 to start real-time acquisition, and the sweep frequency signal is amplified by the vibration drive plate 3-4, so that the vibration unit 3-3 vibrates, causing the duck eggs and the annular egg tray 3-1 to resonate and produce an acoustic response. After the signal is amplified and filtered by the microphone acquisition board 3-2, it is input into the data acquisition card 5, and the data acquisition card 5 inputs the data into the computer 6 for signal processing.

[0075] The present invention selects 200 duck eggs as data for offline detection to ensure the accuracy of data detection. Offline analysis refers to using 200 duck eggs as training samples to construct a discrimination model that can identify cracks according to the characteristic differences of audio signal segments. 100 intact duck eggs are manually screened out, and cracks are artificially created on the other 100 duck eggs, and the operation is performed according to the vibration duck egg detection process.

[0076] According to the hardware configuration described in the embodiment, a typical acoustic response signal can be obtained by detection, and the signal is analyzed by the Welch power spectrum method to obtain typical frequency spectra of cracked eggs and intact eggs. Effective signal features can be extracted from the spectrum lines. 200 duck egg samples were subjected to signal analysis and feature extraction through the device, and used to establish and verify the discrimination model; online analysis refers to online detection of the vibration acoustic signal of a duck egg based on the offline analysis results, and combined with the discrimination model to comprehensively judge whether the poultry egg has cracks.

[0077] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
