Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical formulation experiment technology, and in particular to an automatic chemical dispensing device. Background Technology

[0002] With the continuous advancement of science and technology and the ongoing development of society, the demand for special materials (such as pharmaceuticals) in traditional scenarios is increasing. Taking the fabrication and research of semi-solid lithium batteries as an example, the following explanation illustrates the process: The designed materials are electrolyte, conductive agent, and positive and negative electrode active materials. The fabrication process involves first mixing the active materials and conductive agent evenly, then adding the electrolyte under extremely low moisture conditions and continuing to stir until a semi-solid slurry is obtained. This semi-solid slurry is then pressed onto a current collector, and subsequently, a pouch cell is assembled.

[0003] In this process, the extraction and transfer of electrolyte must be carried out in an anhydrous and oxygen-free environment. The main reasons are as follows: the electrolyte is sensitive to moisture and oxygen, especially moisture, because water will react with the lithium salt in the electrolyte, causing the electrolyte to deteriorate and generate hydrogen fluoride, which is extremely harmful to the environment and human health; therefore, isolation is required. The existing utility model patent with authorization announcement number CN201812879U discloses a glove box syringe-type electrolyte filling machine for electrolyte filling.

[0004] While current research typically involves mixing the active material and conductive agent thoroughly and then adding the electrolyte in an artificially created extremely low-moisture environment such as a glove box or dehumidification room, glove boxes are inconvenient to operate and pose a risk of gas leakage at the glove joints. Dehumidification rooms, on the other hand, require a humidity level no lower than -40%, which can cause discomfort for people spending extended periods in such environments and does not effectively address the issue of hydrogen fluoride generation.

[0005] For the reasons mentioned above, there is an urgent need for an automatic chemical dispensing device that can automatically transfer electrolyte. Utility Model Content

[0052] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0053] like Figures 1-6 As shown, the automatic chemical dispensing device of this utility model includes a frame 1, a liquid suction module 2, a cap screwing module 3, a liquid injection module 4, an electrolyte tank 5, a defoaming machine 6, a first linear module 7, a weighing device 8, and a second linear module 9.

[0054] like Figure 1 As shown, the liquid suction module 2, the capping module 3, and the liquid injection module 4 are arranged in parallel and are slidably connected to the frame 1 through a driving component, and the liquid suction module 2 and the liquid injection module 4 are connected; the electrolyte tank 5 is set on the frame 1 and corresponds to the movable end of the capping module 3; the degassing machine 6 is set on the frame 1 and is located on one side of the electrolyte tank 5;

[0055] As shown in the structure above, see Figure 1 and Figure 2 In the initial state, the capping module 3 corresponds to the electrolyte tank 5; before the mixing begins, conductive agent and electrode active material are put into the degassing machine 6.

[0056] After that, as Figure 4 As shown, the sealing cap of the electrolyte tank 5 is opened using the screw cap module 3;

[0057] Subsequently, as Figure 5 As shown, the liquid suction module 2, the cap screwing module 3, and the liquid injection module 4 move synchronously on the frame 1 under the drive of the driving component, so that the liquid suction module 2 corresponds to the electrolyte tank 5, while the liquid injection module 4 is close to the degassing machine 6;

[0058] Finally, the liquid injection module 4 is activated, and the liquid suction module 2 draws electrolyte from the electrolyte tank 5, and then the liquid injection module 4 injects the electrolyte into the degassing machine 6, thus realizing the automatic injection of electrolyte.

[0059] Then, the electrolyte, conductive agent, and electrode active material are mixed and degassed using a degassing machine 6.

[0060] In this structure, the liquid suction module 2, the cap screwing module 3, and the liquid injection module 4 are slidably connected to the frame 1, so the position of each module can be freely adjusted. The cap screwing module 3 can open or close the sealing cap of the electrolyte tank 5, while the liquid suction module 2 and the liquid injection module 4 can cooperate with each other to draw electrolyte from the electrolyte tank 5 and input it into the degassing machine 6, thereby performing automated component proportioning. This eliminates the need for manual operation, thus avoiding the problems of physical discomfort to experimental personnel caused by low humidity environment and safety hazards caused by gas leakage.

[0061] Specifically, the frame 1 is equipped with clamps to fix the electrolyte tank 5 and the degassing machine 6, so as to fix the electrolyte tank 5 and the degassing machine 6, thereby facilitating the unscrewing module 3 to unscrew the sealing cap of the electrolyte tank and ensuring the stability of the degassing machine 6.

[0062] like Figure 3 As shown, the cap screwing module 3 includes a first lifting component 31, a cap screwing motor 32, and a chuck 33. The first lifting component 31 is slidably connected to the frame 1; the cap screwing motor 32 is mounted on the first lifting component 31; and the chuck 33 is mounted on the movable end of the cap screwing motor 32.

[0063] As described above, when the capping module 3 is working, the first lifting component 31 drives the capping motor 32 and the chuck 33 to descend synchronously, so that the chuck 33 can engage the sealing cap of the electrolyte tank 5. Then, the capping motor 32 drives the chuck 33 to rotate, thereby unscrewing the sealing cap of the electrolyte tank 5. Afterwards, the first lifting component 31 drives the capping motor 32 and the chuck 33 to reset, at which point the electrolyte tank 5 is in the open state.

[0064] Subsequently, the driving component can move the liquid suction module 2, the cap screwing module 3 and the liquid injection module 4. They rely on sliding cooperation to achieve lateral position adjustment so that the liquid suction module 2 corresponds to the opened electrolyte tank 5.

[0065] In some embodiments, an automatic gripper is used instead of a chuck 33 to hold the sealing cap.

[0066] like Figure 2 As shown, the liquid suction module 2 includes a second lifting member 21 and a liquid suction tube 22, wherein the second lifting member 21 is slidably connected to the frame 1; the liquid suction tube 22 is disposed on the second lifting member 21;

[0067] As described above, when the liquid suction module 2 is working, the second lifting component 21 drives the liquid suction tube 22 to move up and down so that the liquid suction tube 22 can be inserted into the electrolyte tank 5, thereby realizing the extraction of electrolyte.

[0068] like Figure 6 As shown, in some embodiments, the suction tube 22 is configured as a telescopic structure, the tube body 221 is connected to the second lifting member 21 through the sliding sleeve 222, and a pair of rollers 223 are provided to hold the tube body 221, and one of the rollers 223 is connected to a motor. The motor is fixed relative to the sliding sleeve 222. In this way, the motor drives the roller 223 to rotate, and the tube body 221 can move up and down relative to the sliding sleeve 222. This is beneficial to go deeper into the electrolyte tank 5 to extract the electrolyte at the bottom.

[0069] like Figure 3 As shown, the liquid injection module 4 includes a third lifting component 41, a rotary motor 42, a pump 43, an injection needle 44, and a connecting pipe 45. The third lifting component 41 is slidably connected to the frame 1; the rotary motor 42 is mounted on the third lifting component 41; the pump 43 is mounted on the rotary motor 42; the injection needle 44 is connected to the output port of the pump 43; one end of the connecting pipe 45 is connected to the input port of the pump 43, and the other end is connected to the suction pipe 22.

[0070] As described above, the third lifting component 41 is used to adjust the height of the liquid injection module 4. Then, by rotating the motor 42, the orientation of the pump 43 and the liquid injection needle 44 can be adjusted. After the liquid injection needle 44 is aligned with the deaerator 6, the pump 43 is activated to draw electrolyte through the suction pipe 22. The electrolyte is injected into the deaerator 6 in sequence through the suction pipe 22, the connecting pipe 45, the pump 43 and the liquid injection needle 44, thereby realizing automated liquid injection.

[0071] After the liquid injection is completed, the liquid suction module 2 and the liquid injection module 4 self-reset. Then, driven by the drive component, the liquid suction module 2, the cap screwing module 3 and the liquid injection module 4 are laterally displaced to reset. After that, the cap screwing module 3 puts the sealing cap back on to seal the electrolyte tank 5.

[0072] Finally, the capping module 3 self-resets, and at the same time, the degassing machine 6 performs mixing.

[0073] Specifically, the first lifting component 31, the second lifting component 21, and the third lifting component 41 are made of one of the following: a lead screw, an electric push rod, or a cylinder.

[0074] As described above, each lifting component can be a part with linear displacement function, thereby driving the suction tube 22, the capping motor 32 and the pump 43 to adjust their vertical displacement.

[0075] like Figure 2As shown, the first linear module 7 is a driving component. The first linear module 7 includes a lead screw 71, a servo motor 72, a slide rail 73, a slider 74, and a nut seat 75. The lead screw 71 is rotatably mounted on the frame 1; the servo motor 72 is mounted on the frame 1, and the spindle of the servo motor 72 is connected to the lead screw 71; the slide rail 73 is mounted on the frame 1, and the slide rail 73 is parallel to the lead screw 71; the slider 74 is slidably engaged with the slide rail 73, and the liquid suction module 2, the cap screwing module 3, and the liquid injection module 4 are all mounted on the slider 74; the nut seat 75 is threadedly connected to the lead screw 71, and the nut seat 75 is connected to the slider 74.

[0076] As described above, in this solution, the first linear module 7 is used as the driving component to drive the liquid suction module 2, the cap screwing module 3 and the liquid injection module 4 to move laterally.

[0077] When the first linear module 7 is working, the servo motor 72 drives the lead screw 71 to rotate. Then, by relying on the cooperation between the lead screw 71 and the nut seat 75, the liquid suction module 2, the cap screwing module 3 and the liquid injection module 4 can be driven to slide on the slide rail 73 by the slider 74, thereby realizing position adjustment.

[0078] The slide rail 73 is mounted on the frame 1 via a support frame to ensure good load-bearing capacity;

[0079] Specifically, the first lifting component 31, the second lifting component 21, and the third lifting component 41 are connected to the slider 74.

[0080] In some embodiments, the first linear module 7 is replaced by a rodless cylinder.

[0082] As described above, by setting up a weighing device 8 and placing the electrolyte tank 5 and the deaerator 6 on the weighing device 8, the electrolyte tank 5 and the deaerator 6 can be weighed in real time, so as to facilitate the control of the amount of electrolyte added and thus improve the accuracy of the ratio.

[0083] Specifically, the weighing device 8 is equipped with clamps to secure the electrolyte tank 5 and the degassing machine 6.

[0084] like Figure 2 As shown, the degassing machine 6 includes a tank 61, a tank cover 62, and a stirring assembly 63. The tank 61 is mounted on the frame 1; the tank cover 62 is mounted at the opening of the tank 61; and the stirring assembly 63 is mounted on the tank cover 62, with the movable end of the stirring assembly 63 located inside the tank 61.

[0085] As described above, in the structure of the degassing machine 6, the tank 61 is used to contain the conductive agent, active material and electrolyte, the tank cover 62 is used to seal the tank 61, and the mixing of materials is carried out by the stirring assembly 63.

[0086] The stirring component 63 uses a motor to drive the stirring paddle to achieve the stirring operation;

[0087] In this structure, the stirring component 63 is mounted on the tank cover 62, so that after removing the tank cover 62, it is convenient to clean the tank body 61 and the stirring component 63.

[0088] like Figures 1-5 As shown, the second linear module 9 is mounted on the frame 1, and the movable end of the second linear module 9 is connected to the can lid 62.

[0089] As described above, by setting a second linear module 9, the tank lid 62 and stirring assembly 63 of the degassing machine 6 can be raised and lowered to realize automated opening and closing, thereby facilitating the injection module 4 to inject electrolyte into the degassing machine 6.

[0090] In some embodiments, a degassing machine with an automatic lid-opening function is used, thus eliminating the need for a second linear module 9.

[0091] Specifically, the capping module 3, the liquid injection module 4, and the degassing machine 6 are controlled by a Siemens SIMATIC S7-1200CPU 1214CPLC controller or an Omron CP1H-X40DT1-D programmable controller;

[0092] As described above, the controller is used for the electrical control of the capping module 3, the liquid injection module 4, and the defoaming machine 6. It is also used for the electrical control of the first linear module 7, the weighing device 8, and the second linear module 9, so that the modules can work in coordination. This is existing technology and will not be elaborated further.

[0093] This device is used for experimental applications in low humidity environments, such as in a test chamber built with transparent acrylic sheets or in a dehumidification room.

[0098] S4. The first linear module 7 is activated. The servo motor 72 drives the lead screw 71 to rotate. Then, by relying on the cooperation between the lead screw 71 and the nut seat 75, the liquid suction module 2, the cap screwing module 3 and the liquid injection module 4 can be driven to slide on the slide rail 73 by the slider 74, so that the liquid suction module 2 corresponds to the opened electrolyte tank 5.

[0100] S6, the injection module 4 is activated, the third lifting component 41 adjusts its height, and at the same time, the rotary motor 42 drives the pump 43 and the injection needle 44 to rotate synchronously to adjust their orientation so that the injection needle 44 corresponds to the tank 61 of the deaerator 6. Then the pump 43 works to draw electrolyte through the suction pipe 22. The electrolyte is injected into the deaerator 6 in sequence through the suction pipe 22, the connecting pipe 45, the pump 43 and the injection needle 44.

[0101] S7. After the electrolyte injection is completed, the liquid absorption module 2 and the liquid injection module 4 will automatically reset.
