Description

Technical Field

[0001] The utility model belongs to the technical field of biological laboratory appliances, and particularly relates to a multi-channel chicken embryo punching device. Background Art

[0002] Chicken embryos are commonly used in biological laboratories. Chicken embryo inoculation is a common method for cultivating certain viruses. This method can be used for the separation, proliferation, toxicity titration, neutralization test and production of vaccines of certain viruses. Chicken embryos need to be punched before chicken embryo inoculation, and the size of the holes is different according to different experimental types. In the laboratory, a hole puncher is usually used to punch a small hole in the eggshell, and then the size of the hole is enlarged as needed with tweezers. This method is all manual operation, it is easy to crack the eggshell, and the efficiency is relatively low, which cannot meet the requirements of the amount of chicken embryo inoculation; moreover, although there are corresponding automatic punchers in the prior art, the size of eggs purchased in each batch will be different, and the automatic punching can only punch a single hole, and multiple holes cannot be punched at one time. Although the single automatic punching is faster than the manual punching efficiency, it still cannot meet the use requirements, so it is necessary to design a punching device that can punch chicken embryos in batches in view of the current technical deficiencies. Utility Model Content

[0003] Aiming at the above-mentioned deficiencies of the prior art, the utility model invents a multi-channel chicken embryo punching device.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A multi-channel chicken embryo punching device comprises a base, a movable seat, a mounting slot, a punching mechanism, an electric telescopic rod driving mechanism, an egg tray placement slot and a controller. The front end of the base is provided with a movable seat which is lifted and lowered by the movable driving mechanism, and the movable seat is fixedly provided with a mounting slot; two rows of 6 punching mechanisms are provided in the mounting slot, the punching mechanism in the middle is fixedly connected to the mounting slot, and the punching mechanisms on both sides are slidably installed in the mounting slot by a screw driving mechanism respectively; an egg tray placement slot and a controller are provided on the base, and the egg tray placement slot is located directly below the 6 punching mechanisms.

[0006] The innovation of the utility model is to realize the three-dimensional spatial position movement of the punching mechanism by adopting the reasonable combination of the mobile driving mechanism so as to realize the simultaneous punching of multiple chicken embryos on the egg tray.

[0007] Furthermore, the punching mechanism includes a sliding seat, a punching motor, a drill bit, a tool cavity, a tool, a pop-up spring and a pressure sensor. The punching motor is fixedly arranged at the center position of the sliding seat, and the drill bit is fixedly arranged on the main shaft of the punching motor; two tool cavities are symmetrically arranged in the center of the drill bit, and the tool and the pop-up spring are installed in the tool cavity, and the tool is located below the pop-up spring; a pressure sensor is arranged on the top of the pop-up spring, and the tool is designed in a pop-up manner to meet the punching requirements of the curved surface on the eggshell; the distance between the two tools is the size of the hole, and different drill bits can be replaced according to the size of the hole when in use.

[0008] Furthermore, the mounting groove is divided into a first mounting groove and a second mounting groove, and three punching mechanisms are arranged in a row in the first mounting groove and the second mounting groove; the second mounting groove is slidably installed in front of the first mounting groove through a cam driving mechanism, so that the drill bit spacing between rows can be adjusted.

[0009] Furthermore, the screw drive mechanism includes a screw, a first drive motor and a first sliding rod, the screw is a unidirectional screw or a bidirectional screw, the thread on the unidirectional screw is a left-handed or right-handed threaded screw; one end of the thread on the bidirectional screw is a left-handed thread, and the other end is a right-handed thread; the screw drive mechanism has high control accuracy, stable control, and a large range of control movement.

[0010] Furthermore, the electric telescopic rod driving mechanism comprises an electric telescopic rod and a second sliding rod. The electric telescopic rod driving mechanism is relatively simple, occupies a small space, and is not complicated to install.

[0011] Furthermore, the cam driving mechanism comprises a second driving motor, a third sliding rod, a cam and a return spring. The cam driving mechanism has a simple structure, occupies a small space, and is suitable for use in fine-tuning the spacing.

[0012] Furthermore, it also includes an infrared rangefinder, which is arranged at the center position of the bottom of the drill bit. The infrared rangefinder is mainly used as a marking line to adjust and judge whether the drill bit is directly above the marking point on the chicken embryo. Moreover, it can also monitor the distance between the drill bit and the chicken embryo.

[0013] Furthermore, the controller includes a touch display screen, a switch button, a direction adjustment button and a control panel. The touch display screen is used to display the operation parameters or modify the corresponding parameters; the switch button is used as a main switch and also as a drilling start button; the direction adjustment button is used to adjust the horizontal coordinate position of the punching mechanism.

[0014] Furthermore, an egg tray is placed in the egg tray placement groove, and a rubber layer is arranged inside the chicken embryo hole of the egg tray. The rubber layer on the egg tray plays a role in fixing the chicken embryo to prevent the chicken embryo from sliding during the punching process.

[0015] The utility model has the advantages that the punching mechanism on the punching device of the utility model can adjust the three-dimensional coordinates under the action of the driving mechanism, so that 6 chicken embryos on the egg tray can be punched at the same time, and the size difference between chicken embryos of different batches can be adjusted. The size difference of chicken embryos of the same batch is not large, so generally no adjustment is required; the tool on the punching mechanism adopts a pop-up design, which will retract under pressure, so as to meet the use requirement that the eggshell is a curved surface; the overall structure is small in size and low in production cost, and can be promoted to most laboratories for use.

[0027] In order to achieve longitudinal adjustment of the punching mechanism 4, the installation slot 3 is divided into a first installation slot 31 and a second installation slot 32. Three punching mechanisms 4 are arranged in a row in the first installation slot 31 and the second installation slot 32, that is, six punching mechanisms 4 are divided into two groups. The second installation slot 32 is slidably installed in front of the first installation slot 31 through a cam driving mechanism.
