[0002] A petri dish is a laboratory dish used for culturing microorganisms or cells. It consists of a flat, disc-shaped base and a lid, and is typically made of glass or plastic. Petri dishes are generally divided into two categories: plastic and glass. Glass can be used for culturing plant materials, microorganisms, and adherent animal cells.

[0003] Since crystallization dish culture dishes have high requirements for the flatness of the bottom of the dish, the traditional method uses a glass tube to directly seal the bottom, which has poor bottom flatness and cannot guarantee high consistency. In addition, mold casting is used, which has poor smoothness and often produces mold marks. The thickness uniformity depends on the professional level of the craftsman and cannot meet mass production requirements.

[0004] Therefore, a bottom sealing device is needed to improve the above problems. Summary of the Invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, a clamping assembly is provided in the bottom sealing device, and one end of a conduit in the clamping assembly is connected to the air inlet of a negative pressure extraction machine, so that the gas at the port of the inner film mold is extracted, which facilitates the adsorption of glass sheets of equal diameter.

After uniform fusion, this is beneficial to solve the problem that the crystallization dish culture dish has high requirements for the flatness of the bottom of the vessel. The traditional method uses a glass tube to directly seal the bottom, but the bottom flatness is poor and the height consistency cannot be guaranteed. In addition, the mold casting is used, which has poor smoothness and often produces mold marks. The thickness uniformity depends on the professional level of the craftsman, and cannot meet the requirements of mass production. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In this embodiment, please refer to Figure 1 、 Figure 2 and Figure 4 The clamping assembly 8 includes a positioning block 801, which is installed on the base surface of the fixed plate 6 through a second bolt 802. The cross-section of the positioning block 801 is a T-shaped structure. An electric rotating three-jaw chuck 803 is installed on the outer wall of the positioning block 801. The rotating disk 704 and the electric rotating three-jaw chuck 803 are located on the same horizontal line. The inner wall of the electric rotating three-jaw chuck 803 is slidably connected with an inner film mold 804. A hydraulic push rod 805 is installed on the outer wall of the inner film mold 804, and a conduit 806 is installed on the outer wall of the inner film mold 804.

[0037] Furthermore, the main controller 13 is connected to the servo motor 9, the electric rotating three-jaw chuck 803, the hydraulic push rod 805 and the electric flame burner 504 through wires, and the connection method is electrical connection, so that the device is powered on. A connecting groove 14 is opened on the inner wall of the mounting groove 2 to facilitate the conduit 806 and the air intake pipe 505 to pass through the connecting groove 14 in sequence, making the pipeline more neat and convenient to operate. The connection method between the drive shaft of the servo motor 9 and the mounting plate 3 is a rotating connection.

The servo motor 9 is provided with two groups and is respectively located on the inner wall of the mounting groove 2. The servo motor 9 provides thrust for the trimming assembly 7 and the clamping assembly 8.

[0038] The working process of the present invention is as follows: when the bottom sealing device designed by the present invention is working, the main controller 13 is connected to the servo motor 9, the electric rotating three-jaw chuck 803, the hydraulic push rod 805 and the electric flame burner 504 through wires, and the connection method is electrical connection, so that the device is powered on, and the glass tube is placed on the inner wall of the electric rotating three-jaw chuck 803 for fixation, and the inner film mold 804 is slidably connected to the inner wall of the electric rotating three-jaw chuck 803, and the hydraulic push rod 805 is installed on the outer wall of the inner film mold 804. Under the action of the conduit 806 installed on the outer wall of the inner film mold 804, one end of the conduit 806 is connected to the air inlet of the negative pressure machine, so that the gas at the port of the inner film mold 804 is sucked into the conduit 806, The gas is extracted, and then it is convenient to absorb glass pieces of equal diameter. A bracket 502 is installed on the outer wall of the limit plate 501, a clamping block 503 is installed on the outer wall of the bracket 502, and an electric-controlled flame burner 504 is installed on the inner wall of the clamping block 503. An air inlet pipe 505 is installed at one end of the electric-controlled flame burner 504. Under the action of the air inlet pipe 505, the air inlet pipe 505 is connected to the natural gas pipeline. When the switch of the main controller 13 is turned on, the main controller 13 controls the operation of the electric-controlled flame burner 504 according to the set program, so that the electric-controlled flame burner 504 sprays out flames, and the firepower is automatically adjusted. A servo motor 9 is installed on the outer wall of the mounting plate 3. The drive shaft of the servo motor 9 passes through the mounting plate 3 and extends to the outer wall of the mounting plate 3, where a threaded rotating rod is connected. 10. One end of the threaded rotating rod 10 is threadedly connected to the fixed plate 6. It is only necessary to turn on the switch of the main controller 13 so that the main controller 13 controls the operation of the servo motor 9. Since the connection between the driving shaft of the servo motor 9 and the mounting plate 3 is a rotational connection, and the connection between the limit plate 501 and the threaded rotating rod 10 is a rotational connection, the driving shaft of the servo motor 9 rotates on the outer wall of the mounting plate 3. At the same time, the driving shaft of the servo motor 9 drives the threaded rotating rod 10 to rotate, so that the threaded rotating rod 10 rotates on the outer wall of the mounting plate 3. At the same time, the threaded rotating rod 10 applies a thrust to the fixed plate 6 under the action of the threaded connection, so that the fixed plate 6 drives the clamping assembly 8 to move to one side, so that the electric rotating three-jaw chuck 803 moves to the electric-controlled flame burner 504. , under the action of the electric flame torch 504 located just below the electric rotating three-jaw chuck 803, the electric flame torch 504 heats the glass tube, and then the switch of the main controller 13 is turned on, so that the main controller 13 controls the electric rotating three-jaw chuck 803 to operate according to the set program, so that the electric rotating three-jaw chuck 803 drives the inner film mold 804 to rotate and adjust the firing position, and then the switch of the main controller 13 is turned on, so that the main controller 13 controls the hydraulic push rod 805 to operate with pressure, so that one end of the hydraulic push rod 805 is pushed to one side, so that the bottom of the glass piece of equal diameter slowly moves to one side of the glass tube, and finally the glass tube and the glass piece are fused together. After the fusion is uniform, the edge is trimmed to complete the bottom sealing.This helps solve the problem that the bottom flatness of crystallization dishes is very high. The traditional method uses glass tubes to seal the bottom directly, which has poor bottom flatness and cannot guarantee high consistency. In addition, the use of mold casting has poor smoothness and often produces mold marks. The thickness uniformity depends on the professional level of the craftsman and cannot meet the needs of mass production.

[0039] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
