The screwdriver bit assembly 4-5 comprises a motor 4-51, a driving rod 4-52 connected with an electrode shaft and a screwdriver bit 4-53 connected with the tail end of the motor driving rod 4-52. The photoelectric detection device 4-7 is arranged at the lower part of the vertical plate 4-1 and is used for detecting whether the tube cover of the freezing tube is opened or not.
The push plate 4-3 is arranged at the lower part of the head accommodating frame 4-2, and the push plate driving device 4-4 can drive the push plate 4-3 to move up and down relative to the head accommodating frame 4-2. The push plate 4-3 is provided with a plurality of through holes, and the driving rod 4-52 passes through the through holes. The diameter of the through hole is smaller than that of the tube cover of the freezing tube.
The basic working process of the filling system is as follows: the empty freezing storage tubes 8 are placed in the insertion holes 3-21 of the freezing storage tube carrier units 3, the freezing storage tube carrier units 3 are fixed on the carrier unit driving device 10, the carrier unit driving device 10 drives the freezing storage tube carrier units 3 to move leftwards, the two rows of freezing storage tubes 8 are aligned with the two rows of batch heads 4-53, the batch head accommodating frames 4-2 move downwards, the batch heads 4-53 are inserted into the corresponding covers 8-1 of the freezing storage tubes 8, and in order to enable the batch heads 4-53 to be accurately inserted into the covers 8-1, the motors 4-51 can drive the batch heads 4-53 to perform micro-motion rotation. After the batch head 4-53 is inserted into the cover 8-1, the motor 4-51 drives the batch head 4-53 to rotate, and meanwhile, the batch head accommodating frame 4-2 moves upwards, so that the uncapping process is finished, namely, uncapping operation is carried out on two rows of freezing pipes 8 each time, and at the moment, the cover 8-1 is clamped on the batch head 4-53;
the freezing pipe carrier unit 3 continues to move leftwards, when the first row of freezing pipes 8 is aligned with the filling needles 6-3, the peristaltic pump filling unit 5 is controlled to inject liquid medicine into the freezing pipes 8, and then the freezing pipe carrier unit 3 continues to move leftwards, and the second row of freezing pipes 8 is aligned with the filling needles 6-3 and is injected with liquid medicine.
Subsequently, the freezing storage pipe carrier unit 3 moves rightwards to the lower part of the cover opening and closing unit 4, the batch head 4-53 is aligned to the freezing storage pipe 8, the batch head accommodating frame 4-2 moves downwards, the motor 4-51 is started to drive the batch head 4-53 to rotate, and the cover on the batch head 4-53 is screwed into the freezing storage pipe; and then stopping the motor 4-51, controlling the batch head accommodating frame 4-2 to move upwards, and simultaneously controlling the push plate 4-3 to move downwards, so that the batch head 4-53 is separated from the cover 8-1 of the freezing storage tube, thereby preventing the freezing storage tube from moving upwards, and completing the cover closing process.
The freezing tube carrier unit 3 continues to move leftwards, and the filling operation of the subsequent freezing tube is completed according to the method.
Compared with the prior art, the method has the advantages that (1) the plurality of head-batch assemblies form a plurality of rows (preferably two rows), and the head-batch assemblies in the plurality of rows can be controlled simultaneously when the cover is opened and closed each time, so that compared with the prior art, the freezing tube filled in unit time is improved in multiple times, and the filling efficiency is greatly improved; (2) After closing the cover, the push plate moves downwards to press the freezing pipe cover, and as the diameter of the through hole in the push plate is smaller than that of the freezing pipe cover, the push plate can press the freezing pipe, so that the freezing pipe is prevented from being driven to move upwards by the batch head when the batch head is separated from the cover of the freezing pipe, and compared with a complex clamp for clamping the freezing pipe in the prior art, the invention is simpler, and the invention can be well suitable for filling a plurality of rows of freezing pipes at one time.
The following describes a process of detecting the uncapping state by the photodetection device 4-7, wherein the photodetection device 4-7 can emit a beam of light 4-71 (for example, infrared ray) in the column direction where the freezing storage tube is located, the height of the light is consistent with the height where the freezing storage tube cover is located, and the photodetection device 4-7 judges whether the uncapping of the column of freezing storage tubes is completed according to the shielding and reflection conditions of the emitted light. When a row of freezing pipes with the uncaps not correctly exist, light rays are blocked, the uncapping failure is primarily judged at the moment, the row of freezing pipes can perform uncapping operation again and then are re-detected, if the uncapping failure still exists, the uncapping failure of the row of freezing pipes is judged, namely, each row of freezing pipes has the fault tolerance of two uncapping failures, and if the uncapping failure of the row of freezing pipes is finally judged, the filling operation is not performed on the row of freezing pipes.
The photoelectric detection device can detect the uncovering condition of a row of freezing storage tubes each time, improves the efficiency by setting the fault tolerance rate for two times, and greatly reduces the cost of the detection method and the detection equipment compared with the prior art.

Since the first shape is substantially polygonal, and the boundary of the groove 8-2 is formed by rotating the reference shape to a certain extent, when the head 4-53 moves down to the groove 8-2, the groove 8-2 has a plurality of shapes that can be matched with the periphery of the first guiding surface (for example, in fig. 4B, two squares are actually matched with the first shape formed by the first guiding surface in fig. 3C, two triangles are matched with the first shape in fig. 5, and four triangles are matched with the first shape in fig. 6), so that the head 4-53 can be smoothly inserted into the bottle cap without or only by rotating the head 4-53 by a small angle. In addition, since the reference shape is slightly smaller than the first shape, the cap 8-1 can clamp the bits 4-53 by elastic deformation, and the cap 8-1 can be disengaged from the freezing vial body when the cap is opened.
Through such design for after the frozen storage pipe uncapped, the tube cap of frozen storage pipe firmly combines together through elastic deformation with criticizing the head, criticizes the head and is lifted the back with the lid, waits for frozen storage pipe filling to finish, directly carries out the operation of closing the lid.
