Therefore, an injection head is needed to inject the virus into the fertilized eggs of 5-10 days of incubation. However, during the injection process, due to improper selection of parameters such as needle shape, needle thickness, needle speed, needle module weight, crack (micro-crack) eggs will be produced, resulting in virus culture failure. During virus culture, due to the different varieties, origins, feeding methods, etc. of the eggs, the mechanical properties of the eggshells are different, and the injection parameters must be adjusted (otherwise the eggshells will crack, resulting in virus culture failure). Furthermore, in addition to chicken embryos (eggs), when other poultry eggs (such as duck eggs, etc.) are injected with viruses, different injection parameters need to be changed.

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0025] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the drawings are all simplified and not in exact proportion, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.
[0026] like Figure 1 As shown, the lifting platform part of the present invention is illustrated, the preferred mechanism of the chicken embryo virus injection head of the present invention comprises a lifting platform 1, a vibration-absorbing egg tray 3-9 for accommodating chicken embryo eggs and a CCD camera 3-2, the lifting platform 1 comprises a lifting plate 1-5 and a plurality of polished rods 1-7, the lifting plate 1-5 is horizontally arranged and sleeved on the plurality of polished rods 1-7, and is slidably connected to the plurality of polished rods 1-7, a counterweight 1-2 is placed on the upper surface of the lifting plate 1-5, a side hole needle 1-9 is vertically arranged downward in the middle position of the lower surface of the lifting plate 1-5, and the vibration-absorbing egg tray 3-9 is located directly below the middle position of the lower surface of the lifting plate 1-5; the CCD camera 3-2 is movably arranged above the side of the vibration-absorbing egg tray 3-9;
[0027] Under the action of gravity, the lifting plate 1-5 descends along the multiple polished rods 1-7, and the side hole needle 1-9 pierces the eggshell; the lifting plate 1-5 is removed, and the CCD camera 3-2 is moved in so that it is located directly above the vibration absorbing egg tray 3-9, and the eggshell of the chicken embryo egg is photographed to determine whether the chicken embryo egg has cracks. The counterweight 1-2 can be replaced to change the initial weight of the needle injection system.
[0028] The lifting platform 1 also includes a magnetic sleeve 1-6, which is sleeved on the multiple light rods 1-7. The multiple light rods 1-7 are also respectively sleeved on buffer devices, and the buffer devices are located below the magnetic sleeve 1-6.
[0029] like Figure 2 The figure shows the structure of the buffer device 2. The buffer device comprises an upper adsorption surface 2-2 of the electromagnet, an electromagnet coil 2-3, a lower adsorption surface 2-4 of the electromagnet, a damping spring 2-6 and a magnetic fixing seat 2-7, the upper adsorption surface 2-2 of the electromagnet is arranged at the upper end of the electromagnet coil 2-3, the lower adsorption surface 2-4 of the electromagnet is arranged at the lower end of the electromagnet coil 2-3, and the damping spring 2-6 is connected between the electromagnet coil 2-3 and the magnetic fixing seat 2-7.
[0030] During injection, the photoelectric switch 5 determines that the lifting plate 1-5 with the side hole needle head descends along the light rod 1-7, and then controls the electromagnet coil 2-3 to be energized, the magnetic sleeve 1-6 is adsorbed to the upper adsorption surface 2-2 of the electromagnet, and the magnetic fixing seat 2-7 is adsorbed to the lower adsorption surface 2-4 of the electromagnet to reduce the vibration generated by the lifting plate 1-5.
[0031] like Figure 3As shown, the installation structure of the CCD camera 3-2 is illustrated. The CCD camera 3-2 is installed on the CCD camera bracket 3-1, and a coated convex lens 3-3 is also provided on the CCD camera bracket 3-1. The coated convex lens 3-3 is located below the CCD camera 3-2. The CCD camera 3-2 photographs the eggshell of the chicken embryo egg through the coated convex lens 3-3. Through the coated convex lens 3-3, the camera 3-2 can magnify and photograph the eggshell injection hole to determine whether there is a crack in the eggshell.
[0032] like Figure 4 As shown, the present invention also includes a relatively arranged scale 4-3 and a high-speed camera 4-2, which are respectively located on both sides of the vibration-absorbing egg tray 3-9. The high-speed camera 4-2 shoots during the descent of the side hole needle 1-9, and is used to shoot the position of the side hole needle 1-9 on the scale to obtain the speed of the side hole needle 1-9.
[0033] like Figure 5 As shown, the interior of the vibration-absorbing egg tray 3-9 is provided with an egg-illuminating light source 3-9-3, the vibration-absorbing egg tray 3-9 is concave to form a receiving cavity, the bottom opening of the receiving cavity is used as a light source through hole, the inner wall of the receiving cavity is provided with vibration-absorbing cotton, and the upper outer edge plane of the vibration-absorbing egg tray 3-9 is covered with a black shading cloth 3-5. The egg-illuminating light source 3-9-3 illuminates the egg embryo after injection to make the cracks clearer. The vibration-absorbing cotton 3-9-2 is consistent with the shape of the eggshell, which not only supports the egg embryo, but also absorbs vibration.
[0034] After the image captured by the CCD camera 3 - 2 is gray-scaled and binarized, edge detection is performed on the image, and a contour is drawn based on the result of the edge detection, and whether there is a crack is determined based on the contour.
[0035] like Figure 6-8 The overall structure and state of the present invention are shown in FIG. The working process and steps are described as follows in conjunction with the accompanying drawings:
[0036] 1. Initial injection velocity detection
[0037] The lifting platform is fixed to the linear bearing, and the linear bearing descends along the light rod. After the photoelectric switch detects the lifting platform, the high-speed camera starts working, and the electromagnet coil of the buffer device starts to be energized. A ruler is placed vertically opposite the high-speed camera to facilitate the calculation of the initial injection velocity V0.
[0038] 2. The needle of the side hole pierces the eggshell
[0039] The needle of the side hole pierces the blunt end of the chicken embryo (breeding egg). At this time, the electromagnet is energized and has magnetism. The groove at the bottom of the magnetic sleeve collides with the annular rubber protrusion on the upper adsorption surface of the electromagnet of the buffer device. After the collision, the bottom of the magnetic sleeve and the upper adsorption surface of the electromagnet are adsorbed together. The lifting platform continues to compress the shock-absorbing spring of the buffer device. After a certain distance of compression, the annular rubber protrusion on the lower adsorption surface of the electromagnet is embedded in the groove of the lower magnetic fixing seat and plays a buffering role. At this time, the lower adsorption surface of the electromagnet is adsorbed together with the magnetic fixing seat. The function of the buffer device is to prevent the needle from vibrating during the injection process and rebounding after the injection, and to avoid cracks caused by other factors.
[0040] 3. Injection hole micro crack detection
[0041] After the injection is completed, the lifting platform is reset, the steering gear is started, and the CCD camera and the coated convex lens are driven by the steering gear to move to the top of the chicken embryo (breeding egg). There is an egg light source inside the vibration-absorbing egg tray. With the help of the egg light source and the coated convex lens, the CCD camera can obtain a very clear image, which is convenient for micro-crack detection. The function of the black shading cloth is to eliminate external light interference and obtain a clearer image.
[0042] The chicken embryo virus injection head optimization mechanism of the present invention can form a chicken embryo virus injection head optimization method.
[0043] Although the embodiments are described and illustrated separately above, some common technologies are involved. It is the opinion of ordinary technicians in this field that the embodiments can be replaced and integrated. If the content is not clearly recorded in one of the embodiments, reference can be made to another recorded embodiment.
[0044] The above only describes the preferred embodiments of the present invention, but it should not be understood as limiting the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to be changed. In short, all changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
