Description

Technical Field

[0001] The invention relates to the technical field of medical automation, and in particular to a lifting mechanism for automatically collecting microbial culture dishes. Background Art

[0002] At present, in the medical field, the health of the people and the corresponding awareness are increasingly valued by all parties. The effects of antibiotics in the medical field and on people's health are very significant. However, due to the lack of understanding of antibiotics in the past, the use of antibiotics has been abused, which has brought certain negative effects on the health of the people. Therefore, when the masses are sick, medical workers will gradually adopt more scientific and stable ways and methods to treat patients. The current practice is that medical personnel use an inoculation loop to take an appropriate amount of samples from the sampling tube, inoculate and mark on a blank culture dish, and manually place them in the incubator after accumulating an appropriate number. The next day, the medical staff opens the incubator to observe the growth of the culture dish. The current methods and methods are all manual operations, which are not only time-consuming and labor-intensive, but also have a long cycle. Due to the possibility of fatigue of medical staff, it is easy to cause certain mistakes. Therefore, it is necessary to find an automated way and method. The use of automated methods and methods will inevitably involve the recovery of the culture dish. Therefore, it is necessary to design a structure to solve the problem of automatically transporting the culture dish in the conveying track to the recovery mechanism. Summary of the invention

[0004] According to the prior art described in the background technology of this patent, since the current process of culturing patient body fluids and prescribing the right medicine is carried out manually from beginning to end, it is necessary to find an automated way and method to carry out the process. The use of automated ways and methods will inevitably involve the recovery of culture dishes, so it is necessary to design a structure to solve the problem of automatically transporting the culture dishes in the conveying track to the recovery mechanism; and the lifting mechanism for automatic collection of microbial culture dishes disclosed in the present invention can automatically intercept the culture dishes on the culture dish conveying track through blocks, and transport the intercepted culture dishes to the culture dish recovery mechanism through a lifting plate. Therefore, the lifting mechanism for automatic collection of microbial culture dishes of the present invention can automatically transport the culture dishes on the culture dish conveying track to the culture dish recovery mechanism located directly above it, freeing the operator from repetitive actions, reducing labor intensity, and improving collection efficiency. It has a simple structure, reliable performance, and provides convenience for subsequent automation.

[0005] In addition, the lifting mechanism for automatic collection of microbial culture dishes disclosed in the present invention also has the following additional technical features:

[0006] Furthermore, the linear drive mechanism includes a rotational drive source, a ball screw fixedly connected to the output end of the rotational drive source through a coupling, a ball screw nut threadedly connected to the ball screw, and a lifting block fixed on the ball screw nut, the lifting block having the through groove, and the lifting block is fixedly connected to the lifting part of the culture dish.

[0007] Furthermore, the rotation drive source is a stepping motor.

[0008] Furthermore, the lifting mechanism also includes a base, the base of the rotary drive source is fixedly mounted on the base, a linear slide rail is also arranged on the base, and the lifting block is slidably arranged on the linear slide rail.

[0009] Furthermore, a light shielding sheet is installed on the lifting block, a photoelectric switch bracket is installed on the base, and a photoelectric switch is installed on the photoelectric switch bracket for limiting the rising height of the lifting part of the culture dish in cooperation with the light shielding sheet.

[0010] Furthermore, the elastic member is a compression spring.

[0011] Furthermore, a shaft sleeve is arranged between the blocking rod and the through slot.

[0012] Furthermore, the lifting mechanism for automatic collection of microbial culture dishes is arranged directly below two parallel culture dish conveying tracks, N is 2, the two culture dish limiting mechanisms are respectively located directly below the two culture dish conveying tracks, and the lifting plate is located between the two culture dish conveying tracks.

[0013] Furthermore, the culture dish lifting portion includes a connector fixedly connected to the output end of the linear drive mechanism and a lifting plate fixedly connected to the connector, and a width of the lifting plate is smaller than a distance between the two culture dish conveying tracks.

When the two ends of the elastic member are respectively abutted against the upper limit plate and the output end of the linear drive mechanism, the block moves upward under the action of the elastic member and passes through the through hole on the culture dish conveying track. The upper limit plate cannot pass through the through hole and abuts against the lower side of the culture dish conveying track. The block stops moving upward, while the lifting block continues to move upward under the drive of the stepper motor. The elastic member is compressed. When the lifting plate connected to the lifting block through the connecting tube reaches the lower end of the culture dish conveying track plane, the stepper motor stops moving upward. The feed motor stops rotating, at which time the block can intercept the culture dish on the culture dish conveying track, and the lifting plate is below the track and will not interfere with the movement of the culture dish on the track to the position against the block; after the culture dish is blocked by the block, the stepper motor rotates, the lifting block drives the lifting plate to rise, and pushes the culture dish limited by the block upward, the elastic part continues to be compressed, and when the lifting plate transports the culture dish to the recovery mechanism, the photoelectric switch is triggered by the light blocking piece to complete the lifting action, the stepper motor rotates in the opposite direction, the lifting block drives the lifting plate to descend, at this time the block does not move, and when the lifting block descends to contact with the lower limit piece, the block is driven to descend simultaneously with the lifting block until it returns to the starting state.

Figure 6 As shown in FIG. 1 ), the stepper motor 1 rotates in the opposite direction, and the lifting block 10 drives the lifting plate 17 to descend. At this time, the stopper 8 does not move. When the lifting block 10 descends to contact the lower limit plate 11, the stopper 8 is driven to descend together with the lifting block 10 until it returns to the position shown in FIG. Figure 1 The starting state is shown.
