For example, covered culture dishes and other carriers are used to proliferate cells. In the cell culture unit, the culture medium usually needs to be refrigerated. Therefore, the culture medium container is placed in a cold room, and the culture medium is transferred from the culture medium container to the culture container via a pipeline. The culture dish is then placed in an incubator, and the appropriate temperature and humidity are set to culture the cells. The traditional incubator consists of a box body, a support frame, a temperature control device and a humidity control device. It plays an important role in pharmaceutical, biochemical, and medical fields. The incubator with this structure has the advantages of simple structure, easy use and low cost. It is currently the most widely used incubator for cell culture.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides a biological cell culture device for biological experiments, which has the following beneficial effects:

[0022] 1. When the present invention is in use, culture fluid and cell unit groups are added to the culture dish, and the culture dish cover can be placed on the placement table after it is covered. When there are many culture dishes, the door panel can be opened and the culture dishes can be directly placed in the culture chamber, and multiple culture chambers can also be opened and temperature-controlled independently, so that different cell unit groups that need to be cultured can be placed in multiple culture chambers. In addition, when there are already cultured cell unit groups in the culture chamber, the second motor is first started to drive the screw to rotate, and the rotation of the screw drives the connection part to move the sealing plate by using the threaded hole. When the sealing plate moves, it moves in the card strip, so that the sealing plate can be removed from the outlet, and then the clamping mechanism can be moved to the outlet to clamp the culture dish through the transverse movement mechanism and the lifting assembly, and then the transverse movement mechanism and the lifting assembly can be reset and moved into the box body and the culture dish can be placed on the corresponding placement table, so that different cell unit groups can be cultivated, and it is convenient to assist technicians in taking and placing culture dishes during cultivation.

[0023] 2. The lateral movement mechanism and the lifting assembly mechanism provided in the present invention can be used together to drive the clamping mechanism to move in the X-axis direction and the Y-axis direction, so as to correspond to the culture dishes on the placement table distributed in the matrix of the clamping. The lateral movement mechanism uses the first reduction motor as the power to drive the gear to rotate. When the gear rotates, it rolls on the rack, so that the base, the lifting assembly and the clamping mechanism can be driven in the opposite direction to move to the specified position. After reaching the specified position, the lifting mechanism uses the first motor as the power to drive the screw rod to rotate. When the screw rod rotates, the thread drives the threaded sleeve to move. When the threaded sleeve moves, the cross tube is moved through the connecting block and the fixed plate. When the cross tube moves, the clamping mechanism can be moved to the specified height. At this time, the second reduction motor drives the main shaft to rotate the vertical tube The vertical tube rotates, and the clamping mechanism faces the placement table. The first electric push rod drives the slider to move the transverse mechanism on the Z axis, so that the clamping mechanism facing the placement table can be extended into the culture chamber. The culture dish can be clamped by the clamping mechanism. Finally, the first electric push rod is reset, the second reduction motor is reversed to reset the vertical tube, the lifting mechanism moves the clamping mechanism to a position corresponding to the outlet height, and the first reduction motor drives the base to move the lifting assembly and the clamping mechanism to one side of the box. Finally, the culture dish is sent out of the box from the outlet after the sealing assembly is opened. Therefore, the culture dish can be taken out of the equipment without opening the equipment to observe the culture progress during the cultivation process, and the stable culture environment in the equipment is not affected.

[0024] 3. The clamping mechanism provided in the present invention, when in use, starts the third reduction motor to drive the worm to rotate the two worm wheels. When the two worm wheels rotate, they can drive the two transmission rods to swing relative to each other through the rotating shaft. When the transmission rods swing, they drive the support shaft and the sliding sleeve to slide on the rod wall of the rectangular rod. When the support shaft slides, it drives the clamping plate to move, so that the culture dish can be clamped, and the anti-slip rubber pad provided on the clamping plate can protect the culture dish and avoid scratching the surface of the culture dish during clamping.

[0025] 4. The rectangular plate provided in the present invention can form a sealing structure with the first baffle, the second baffle and the frame. The second electric push rod can drive the movably installed second baffle to move down to the lower dead point. When displacement occurs, the second pick-up and release port coincides with the first pick-up and release port. At this time, the clamping mechanism can extend into the culture chamber to clamp culture dishes at different positions. When the second baffle is at the upper dead point, the second baffle can cover the first pick-up and release port on the first baffle. In this way, the culture dish can be placed in a relatively sealed culture chamber. During the culture process, since the temperatures required for culturing different cell unit groups are also different, the air intake can be controlled by the opening angle of the electric control air valve. When the air intake is small, the amount of hot air delivered is also small. In this way, the temperature in the culture chamber can be controlled within a certain range and can be monitored by a temperature sensor. The temperature sensor can also be installed in the culture chamber, so that multiple cell unit groups can be cultured in different areas with different culture environments.

When displacement occurs, the second pick-up and release port 21 coincides with the first pick-up and release port 29. At this time, the clamping mechanism can extend into the culture chamber to clamp the culture dish 11 at different positions. When the second baffle 12 is at the upper dead point, the second baffle 12 can cover the first pick-up and release port 29 on the first baffle 28. In this way, the culture dish 11 can be placed in a relatively sealed culture chamber. During the culture process, since the temperatures required for culturing different cell unit groups are also different, the air intake can be controlled by the opening angle of the electric control valve. When the air intake is small, the amount of hot air delivered is also small. In this way, the temperature in the culture chamber can be controlled within a certain range and can be monitored by the temperature sensor 33. The temperature sensor 33 can also be installed in the culture chamber, so that multiple cell unit groups can be cultured in different areas with different cultivation environments.
