DETAILED DESCRIPTION

[0009] like Figure 1 , Figure 2 As shown, the high-pressure sterilizing pot includes a pot body 11 and a plurality of storage frames 12 stacked in the pot body 11. The side walls and the bottom of the storage frames 12 are both grid-like structures. A base 13 is placed on the bottom of the pot body 11. A first pull rod 14 is provided at two symmetrical positions on the inner wall of the storage frame 12.

[0010] like Figure 1 , Figure 3 As shown, this embodiment provides a high-pressure sterilizer storage frame taking and placing device, which is used for taking and placing the storage frame 12 , and the device includes a support frame 2 , a lifting mechanism 3 and a clamping mechanism 4 .

[0011] Specifically, the support frame 2 includes a vertical plate 21, a horizontal plate 22 and a disc 23. The vertical plate 21 is fixed on the top of the pot body 11, and the horizontal plate 22 is arranged on the top of the vertical plate 21, and the two form an inverted L shape. The disc 23 is suspended below the horizontal plate 22 through two support plates 25.

[0012] Specifically, Figure 3 , Figure 4 , Figure 8 As shown, the lifting mechanism 3 includes a first motor 31, two mutually meshing bevel gears 32, a screw rod 33, a square tube 34 and a sleeve 35. The first motor 31 is arranged between one of the support plates 25 and the vertical plate 21. The output shaft of the first motor 31 passes through the support plate 25 and is connected to one of the bevel gears 32. A smooth rod 321 is provided at the bottom of the other bevel gear 32. The smooth rod 321 rotates and fits and passes through the center of the disc 23. Note that the smooth rod 321 does not slide downward. The bottom of the smooth rod 321 is connected to the screw rod 33. The sleeve 35 is suspended below the disc 23 through two reinforcement rods 351. The sleeve 35 is provided with a square groove that passes through itself from top to bottom. A threaded groove is provided in the center of the square tube 34. The square tube 34 is threadedly connected to the screw rod 33 through the threaded groove. The bottom of the square tube 34 slides through the square groove and is connected to a transition column 341. The bottom of the transition column 341 is connected to the clamping mechanism 4.

[0013] Specifically, the clamping mechanism 4 is located directly above the base 13 and is used to clamp the two first pull rods 14 on the storage frame 12. When the clamping mechanism 4 is projected downward, it is located within the storage frame 12. There are many ways to implement the clamping mechanism 4. In order to effectively and conveniently clamp the two first pull rods 14, the specific implementation method of this embodiment is as follows: like Figure 4 As shown, the clamping mechanism 4 includes a control box 43 and two clamping plates 42 arranged at the bottom thereof. The control box 43 is used to adjust the distance between the two clamping plates 42. The opposite outer walls of the two clamping plates 42 are provided with clamping grooves 421, which are used to clamp the corresponding first pull rod 14.

[0014] Method of use: The experimenter moves the storage frame 12 containing the experimental utensils to the clamping mechanism 4 or uses other mechanical arms to automatically transfer the storage frame 12 to the clamping mechanism 4; the regulating box 43 slowly expands the distance between the two clamping plates 42 until the clamping groove 421 clamps the corresponding first pull rod 14; the first motor 31 drives the bevel gear 32 to cause the smooth rod 321 and the screw rod 33 to rotate. Because the square tube 34 is threadedly connected to the screw rod 33 and is limited by the sleeve 35, when the screw rod 33 rotates, the square tube 34 will not move with it. The square tube 34, the transition column 341 and the clamping mechanism 4 will move downward as a whole until the first storage frame 12 is lowered into the pot body 11; the clamping plate 42 releases the first storage frame 12, and the first motor 31 reversely drives the bevel gear 32 to reset the clamping mechanism 4 upward to the initial position, and the above process is repeated until the second and third storage frames 12 are lowered into the pot body 11, and high-pressure sterilization begins; after high-pressure sterilization, the storage frames 12 in the pot body 11 can be automatically taken out one by one by using the pick-and-place device.

[0015] The above solution solves the technical problem of automatically taking out the object frame 12. In order to solve the technical problem of automatically cleaning the inner wall of the pot body 11, the following measures are taken for this embodiment: like Figure 5-Figure 8 As shown, the device also includes a rotating mechanism 5 and a cleaning cylinder 6. The rotating mechanism 5 includes a first synchronous wheel 51, a second synchronous wheel 52, a synchronous belt 53 and a second motor 54. The second motor 54 is arranged on the outer wall of the vertical plate 21. The top of the output shaft of the second motor 54 is connected to the first synchronous wheel 51. The vertical plate 21 is provided with a window 211 that runs through it. The synchronous belt 53 is located in the window 211. The synchronous belt 53 is sleeved on the outer periphery of the first synchronous wheel 51 and the second synchronous wheel 52. The outer wall of the disc 23 is provided with a circle of grooves. The second synchronous wheel 52 rotates in the groove. The support frame 2 also includes two limiting tubes 24 fixedly arranged at the bottom of the second synchronous wheel 52. Two guide rods 41 are fixedly arranged on the top of the clamping mechanism 4. The guide rods 41 slide up and down and fit in the corresponding limiting tubes 24. The top of the clamping mechanism 4 is rotatably connected to the transition column 341. A cleaning brush is provided on the outer wall of the cleaning cylinder 6. A second pull rod 61 is provided at two symmetrical positions on the inner wall of the cleaning cylinder 6.

[0016] Instructions for use: The experimenter moves the cleaning cylinder 6 to the clamping mechanism 4 or uses other robotic arms to automatically transfer the cleaning cylinder 6 to the clamping mechanism 4; the control box 43 slowly expands the distance between the two clamping plates 42 until the clamping groove 421 clamps the corresponding second pull rod 61; on the one hand, the first motor 31 drives the bevel gear 32, causing the square tube 34, the transition column 341, the clamping mechanism 4 and the cleaning cylinder 6 to move downward as a whole, and on the other hand, the second motor 54 drives the first synchronous wheel 51 and the second synchronous wheel 52, and the second synchronous wheel 52 causes the two limiting tubes 24, the two guide rods 41, the clamping mechanism 4 and the cleaning cylinder 6 to rotate, that is, the cleaning cylinder 6 can move up and down and rotate at the same time, so that the cleaning cylinder 6 can be used to clean the pot body 11.

[0017] In order to further improve the stability of the clamping mechanism 4 and the cleaning cylinder 6 during rotation, in this embodiment, a plurality of guide grooves 241 are provided on the side wall of the limiting tube 24 , and a plurality of lugs 411 are provided on the outer wall of the guide rod 41 , and the lugs 411 are slidably matched with the corresponding guide grooves 241 .

[0018] The above solution solves the technical problem of automatically cleaning the inner wall of the pot body 11. In order to solve the technical problem of automatically removing the base 13, the present embodiment adopts the following measures: First, if Figure 9-11 As shown, a plug-in is provided on the control box 43, and the plug-in is used to automatically connect the lock in the base 13 so as to take and place the base 13. The plug-in includes a top plate 71, a bottom plate 72 and two plug-in plates 73 symmetrically arranged on both sides of the control box 43. The plug-in is located between the two clamping plates 42, and the plug-in plate 73 is fixedly connected to the side wall of the control box 43. The plug-in plate 73 is provided with a first groove 731 and a second groove 732 running through it. The top surface of the first groove 731 is lower than the bottom surface of the control box 43, and the second groove 732 is located at the first groove 73 1, the top surface of the second groove 732 is lower than the bottom surface of the clamping plate 42, the top plate 71 and the bottom plate 72 together cross the first grooves 731 of the two plug plates 73, the top plate 71 is not fixed, the bottom plate 72 is fixed, and the bottoms of both ends of the top plate 71 are provided with columns 711, the columns 711 penetrate the bottom plate 72 downward, the outer periphery of the columns 711 is provided with a first spring, and the two ends of the first spring are respectively connected to the top plate 71 and the bottom plate 72, and the top plate 71 is pressed downward by force, so that the two columns 711 can move downward at the same time.

[0019] Then, if Fig.11 , Fig.12 As shown, four jacks 131 are provided on the top of the base 13, and two jacks 131 form a group, and a cavity is formed by the assembly groove 132. A locking member is provided in the assembly groove 132, and the locking member includes a V-shaped plate 83, a second spring 81 and a third spring 82. Fig.12It is a schematic diagram of the connection between the plug-in and the lock in one of the assembly grooves 132. When the plug plate 73 and the column 711 are inserted into the corresponding jack 131, the V-shaped plate 83 opens toward the corresponding column 711. The angle of the V-shaped plate 83 is an acute angle, and the V-shaped plate 83 is rotatably connected to the base 13 at the angle. The second spring 81 is vertically arranged, and a pressure block 84 is connected to the top of the second spring 81. The pressure block 84 is located directly below the corresponding plug plate 73. The third spring 82 is located directly below the corresponding column 711, and the top of the third spring 82 is connected to the first branch section of the V-shaped plate 83. The second branch section of the V-shaped plate 83 is close to a vertical state, but is inclined at a certain angle toward the direction of the first branch section, such as any angle of 5° to 30°. A hook is provided on the outer side of the second branch section of the V-shaped plate 83, and the top surface of the hook is an inclined surface for inserting into the first groove 731.

[0020] The plug-in and the lock are connected as follows: After taking out all the storage frames 12 by using the lifting mechanism 3 and the clamping mechanism 4, the lifting mechanism 3 is used to lower the clamping mechanism 4 to the base 13, and the plug-in plate 73 and the column 711 are slowly inserted into the corresponding plug-in hole 131, and the plug-in plate 73 squeezes the hook on the second branch section of the V-shaped plate 83. Fig.12 When the second groove 732 of the plug plate 73 moves down to the hook, the hook of the V-shaped plate 83 loses the restriction of the plug plate 73 and the hook is inserted into the second groove 732 under the action of the third spring 82, thus completing the connection between the plug and the lock. In this process, the second spring 81 plays a buffering role. After the plug is connected with the lock, the lifting mechanism 3 is used to move the clamping mechanism 4, the plug, the lock and the base 13 upward as a whole, thereby realizing automatic removal of the base 13.

[0021] After taking out the base 13, the base 13 needs to be disassembled from the plug-in. The method is: the experimenter holds the base 13 with one hand and presses the top plate 71 downward with the other hand, so that the two columns 711 move downward at the same time. The columns 711 press down the first branch section of the V-shaped plate 83. Fig.12 From the perspective, the V-shaped plate 83 rotates counterclockwise by a certain angle until the hook of the second branch section of the V-shaped plate 83 disengages from the second groove 732 of the plug plate 73. At this time, the base 13 can be taken out downwards, and the experimenter releases the top plate 71 by hand. The top plate 71 returns to its original position upward under the action of the first spring, and the V-shaped plate 83 returns to its original position under the action of the third spring 82.

[0022] When the base 13 needs to be placed in the pot body 11, two methods can be adopted: first, the experimenter directly lowers the base 13 from the pot mouth of the pot body 11 to the bottom of the pot; second, the experimenter holds the base 13 by hand, and aligns its socket 131 with the corresponding plug plate 73 and the column 711, and then moves the base 13 upward until the hook is inserted into the second groove 732 of the plug plate 73, and uses the lifting mechanism 3 to move the clamping mechanism 4 and the base 13 downward until the base 13 is lowered to the bottom of the pot body 11; the experimenter holds a long rod and presses down the top plate 71, and after the hook is separated from the second groove 732 of the plug plate 73, the lifting mechanism 3 is used to move the clamping mechanism 4 upward.

[0023] The above embodiments are only used to illustrate the technical ideas and features of the present invention, and are not intended to be the only or limit the present invention. It should be understood by those skilled in the art that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention all fall within the scope of protection of the present invention.
