[0016] S300, adjustment process of test operation:

[0017] S301, basic size equipment clamping work: only drive motor A to make a fixed number of turns of power output, and then use the primary drive gear to rotate the primary drive gear ring as a whole so that the extrusion protrusion A sequentially performs a circumferential extrusion action on the spiral extrusion groove A, and the sub-planetary extrusion drive gear is rotated through the extrusion operation, and the planetary gear A is rotated through the rotating sub-planetary extrusion drive gear, and the sun gear A is rotated as a whole based on the rotation locking of the driving planet carrier A, and the extension teeth and the clamping arm assembly are clamped by multiple rotating sun gears A, and the clamping action is adapted to the clamping operation of glassware, volumetric flasks and other large diameter sizes;

[0021] S400, test operation: the multifunctional clamping unit adjusted by the multi-axis robotic arm sequentially adds raw materials and stock solution to carry out test work.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the present invention, a cooling component for the low-temperature operation chamber is arranged at the bottom of the operation cabinet. The component is an existing refrigeration and freezing cooling technology and will not be described in detail. In addition, the pharmaceutical raw materials for internal inspection and testing can be operated through an external control device through the multi-axis robotic arm and the multi-functional clamping unit. The low-temperature operation test device with a robotic arm can realize the test operation with good sealing and heat preservation in a limited and compact space.

[0024] 2. The present invention drives the primary drive gear ring to rotate as a whole through the driving mechanism A, and the rotating primary drive gear ring causes the extrusion protrusion A to perform a circular extrusion action on the spiral extrusion groove A in turn, and the sub-planetary extrusion drive gear is rotated through the extrusion operation, and the planetary gear A is rotated through the rotating sub-planetary extrusion drive gear. Based on the rotational locking of the driving planetary frame A, the sun gear A is rotated as a whole, and the extension teeth and the clamping arm assembly are clamped to expand or close through multiple rotating sun gears A. At the same time, the clamping action is adapted to clamping operations with larger diameters such as glassware and volumetric flasks.

[0025] 3. The present invention forms a buffer compensation cavity through the triangular structure of the clamp arm body, so that the clamp arm body is deformable, and the deformed clamp arm body can adapt to the shape required by different test operations to the outer wall of the container, effectively improving the stability after clamping. And a number of hinged support shaft buckles are used to maintain the basic stability of the clamp arm body.

[0026] 4. The present invention uses the setting of the self-rotating adjustment gear ring to enable the extrusion protrusion B to synchronously rotate and extrude the spiral extrusion groove B, so that multiple driving planetary frames A can adjust the movement. Through this setting, the rotation angle of the clamping arm body can be further adjusted to perform secondary rotation adjustment work to clamp test equipment with smaller diameters such as droppers and test tubes. This operation method performs secondary clamping work based on the primary rotation clamping work of a fixed value.

[0027] 5. The present invention drives the synchronous wheel A and the synchronous wheel B to rotate or lock the central drive shaft and the planetary rotating frame respectively through the driving motor B and the driving motor C, and synchronously forms a planetary transmission structure. After the first-level fixed value rotation of the planetary transmission structure, the driving motor C is locked, and the driving motor B outputs power to rotate the central drive shaft. The central gear set on the top of the central drive shaft drives the multiple key gears on the side to rotate, and the self-rotating key gears make the self-rotating adjustment gear ring rotate as a whole, and the sun gear is synchronously adjusted by the self-rotating adjustment gear ring. Wheel A enables the clamp arm body to further perform secondary rotation adjustment, and through the primary fixed value rotation adjustment, it enables the clamp arm body to be clamped and compensated within a certain range to adapt to the clamping of test vessels and equipment with relatively large diameters; at the same time, based on the primary fixed value rotation adjustment, it cooperates with the above-mentioned secondary rotation adjustment and is compensated for by the clamping of the nautilus block to clamp test vessels and equipment with small diameters, and the rotation adjustment based on the key gear allows the extended connecting shaft to synchronously drive the nautilus block to rotate, and the test tube cover is opened through the nautilus block, effectively improving the functionality of the manipulator.

[0028] 6. The present invention uses a planar spiral nautilus block to enable the nautilus block to rotate around a fixed center point of an extended connecting shaft. The planar spiral feature allows the nautilus block to make rotational frictional contact with vessels and equipment lids with smaller diameters, forcing the lids to rotate and open, thereby effectively avoiding the manual operation of opening the lids. The elastic setting is used to allow both sides of the nautilus block to be compressively deformed, thereby effectively adapting to the rotational opening operation of vessels and equipment lids within a certain size range.

[0029] 7. The present invention uses the return stroke of the micro electric push rod to adjust the overall lifting and lowering of the rotating seat and the limit fork shaft, and in this way, the extended connecting shaft and the nautilus block are synchronously driven to rotate. The nautilus block after rotation is used to push and open the push cover in the container or equipment. At the same time, the rubber end of the dropper is pressed by the forked end of the limit fork shaft based on the lifting and lowering adjustment. The multifunctionality of the single manipulator is realized through the above operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Specifically, the annular flip mechanism 6 includes a sub-planetary extrusion drive gear 601 rotatably arranged in the flip frame 501; a plurality of spiral extrusion grooves A6011 distributed in an annular manner with equal spacing are arranged inside the sub-planetary extrusion drive gear 601, and a driving tooth groove A6012 is arranged on the outer wall of the sub-planetary extrusion drive gear 601; a driving planetary frame A602 is rotatably arranged outside the sub-planetary extrusion drive gear 601, and a plurality of planetary gears A6021 meshing with the driving tooth groove A6012 are arranged in an annular manner with equal spacing inside the driving planetary frame A602, a solar-level rotating cavity is arranged inside the driving planetary frame A602, and a plurality of spiral extrusion grooves A6011 distributed in an annular manner with equal spacing are arranged on the outer surface of the driving planetary frame A602.

The present invention drives the first-stage drive gear ring 604 to rotate as a whole through the driving mechanism A7, and the rotating first-stage drive gear ring 604 causes the extrusion protrusion A6041 to perform a circular extrusion action on the spiral extrusion groove A6011 in turn, and the sub-planetary extrusion drive gear 601 is rotated through the extrusion operation, and the planetary gear A6021 is rotated through the rotating sub-planetary extrusion drive gear 601. Based on the rotational locking of the driving planetary frame A602, the sun gear A603 is rotated as a whole, and the extension teeth 6031 and the clamping arm assembly 8 are clamped to expand or close through multiple rotating sun gears A603. At the same time, the clamping action is adapted to clamping operations with larger diameters such as glassware and volumetric flasks.

[0053] Furthermore, the clamping arm assembly 8 includes a plurality of clamping arm bodies 801 that are hingedly arranged in a circular shape with equal spacing on the basic winding frame 5. The hinged end of the clamping arm body 801 is provided with a secondary driving tooth 8011 that meshes with the extension tooth 6031. The clamping arm body 801 is in a triangular structure, and the internal gap of the clamping arm body 801 forms a buffer compensation cavity; and a plurality of support shaft buckles 8012 are movably hooked inside the buffer compensation cavity. The present invention forms a buffer compensation cavity by forming the clamping arm body 801 in a triangular structure, so that the clamping arm body 801 has deformability, and the deformed clamping arm body 801 can adapt to the outer wall of the vessel required by different test operations, thereby effectively improving the stability after clamping. And a plurality of support shaft buckles 8012 are hingedly arranged to maintain the basic stability of the clamping arm body 801.

[0055] It is worth mentioning that the secondary drive system 10 includes a basic plug-in mounting seat 11 fixedly arranged on the basic winding frame 5; a mounting frame is arranged on the basic plug-in mounting seat 11; a drive motor B12 and a drive motor C13 are symmetrically installed on the mounting frame; the output ends of the drive motor B12 and the drive motor C13 are respectively provided with synchronous wheels A and synchronous wheels B, and a central drive shaft 14 is rotatably arranged on the basic plug-in mounting seat 11 through a bearing seat; a planetary rotating frame 15 is rotatably arranged on the outer wall of the central drive shaft 14 through a bearing; a plurality of key gears 16 are rotatably arranged in a ring shape at equal intervals on the top of the planetary rotating frame 15; and the key gear 16 is meshed and connected with the self-rotation adjustment gear ring 9, and an extension connecting shaft 17 is key-connected inside the key gear 16; the extension connecting shaft 17 is key-connected with the planetary rotating frame 15, and a nautilus block 18 is arranged at the end of the extension connecting shaft 17.
