[0023] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] Such as Figure 1 And Figure 2As shown in the figure, the present application provides an embodiment of an automatic feeding device for new energy silicone raw materials. The new energy silicone raw material feeding device is connected to an automatic dispensing arm, and includes a storage barrel 100. The storage barrel 100 is fixed on a fixed bracket 200 for storing liquid silicone raw materials. The bottom of the storage barrel 100 is provided with a discharge port 130, and the top of the storage barrel 100 is provided with a return port 120 and an openable and closable feeding port. The discharge port 130 is connected to a cam pump 300 through a pipeline. A feeding pipe 400 is connected to the cam pump 300, a return pipe 500 is connected to the return port 120, the feeding pipe 400 is connected to the feeding end of the automatic dispensing arm, and the return pipe 500 is connected to the return end of the automatic dispensing arm. The feeding end and the return end of the automatic dispensing arm are communicated. The liquid silicone raw material enters the automatic dispensing arm along the feeding pipe 400 and then is guided back into the storage barrel 100 along the return pipe 500 to form a flowing cycle, so that the automatic dispensing arm extracts the flowing raw material in the pipeline into the internal mixing chamber for real-time mixing. The fixed bracket 200 raises the bottom end of the storage barrel 100 so that the bottom surface of the storage barrel 100 does not contact the ground. The discharge port 130 can be arranged at the bottom end of the barrel body, so that all the raw materials in the storage barrel 100 are added to the feeding cycle. The cam pump 300 adopts two rotors that move synchronously. The rotors are driven by an external synchronous gearbox. The rotors rotate synchronously in opposite directions driven by a transmission shaft, thus constituting a relatively high vacuum degree and discharge pressure, which is particularly suitable for the transportation of pharmaceutical-grade media and highly corrosive high-viscosity media, and is very suitable for the transportation of liquid silicone raw materials in the present application. The cam pump 300 is used to push the silicone raw material to be transported between the storage barrel 100 and the dispensing arm. The new energy silicone liquid raw material in the storage barrel 100 and the pipeline connecting it to the dispensing arm is in a flowing state. When the raw materials of the automatic dispensing arm are mixed, the automatic dispensing arm extracts the flowing raw material in the pipeline into the internal mixing chamber for real-time mixing. When the automatic dispensing arm extracts the required volume of liquid raw material, it will be smoother, which can ensure stable and continuous feeding, reduce the occurrence of blockages, ensure the accuracy and consistency of the dispensing process, and realize the automatic control of the feeding of new energy silicone raw materials.

[0025] New energy batteries refer to various batteries that can meet the power storage and release requirements in the new energy field, including lithium-ion batteries, nickel-metal hydride batteries, fuel cells, solid-state batteries, etc. Generally made through new technologies and new materials, they have characteristics such as high energy density, long cycle life, and good safety performance. To ensure the safe and reliable operation of new energy batteries, protect the environment, and meet relevant regulatory requirements, it is necessary to conduct sealing and fire prevention for new energy batteries. Generally, new energy silicone is used for sealing to prevent the chemical reactions inside the battery from getting out of control and causing fires, and to avoid the harm and losses caused by battery combustion to personnel and equipment. At the same time, the new energy silicone seal can limit the spread of fire within a single battery or battery pack, reducing the risk of overall losses; prevent the high temperature, smoke, and harmful substances generated by the fire from spreading to the surrounding environment, ensuring the safety of surrounding equipment and personnel; and can also reduce the erosion of the battery by external factors (such as moisture, dust, etc.), maintaining the stable performance of the battery and extending the service life of the battery. When performing the dispensing operation of fireproof silicone for new energy batteries, the automatic feeding device for new energy silicone raw materials in this application can be used as the automatic feeding equipment for new energy silicone raw materials in the dispensing production for new energy battery fire prevention.

[0026] As Figure 3 shown, new energy silicone generally includes liquid A glue and B glue raw materials. The A glue and B glue need to be mixed to cure and form the material shape. The automatic feeding device for new energy silicone raw materials in this application is generally used in pairs. The automatic dispensing arm mixes them in real time and then performs the dispensing operation, which can prevent the silicone from curing and blocking the pipeline, improve the automation degree of production, and improve the accuracy and consistency of dispensing.

[0027] In one embodiment, in the cam pump 300, the pump head 310 of the cam pump 300 is connected to the motor through a coupling 320. The motor is a servo motor 330, and the servo motor 330 provides power for the rotation of the cam pump 300. The rotating shaft of the motor is connected to the pump head 310 through the coupling 320, and the structure of the cam pump 300 is simple. By controlling the rotation of the motor to change the rotation speed of the cam pump 300, the flow rate of the new energy silicone raw materials can be controlled, and the dynamic cyclic supply of the raw materials between the storage barrel 100 and the automatic dispensing arm can be controlled.

[0028] As Figure 2As shown, in one embodiment, the bottom end of the storage barrel 100 is in a downward conical shape, and the discharge port 130 is located at the middle position of the bottom end of the storage barrel 100. The discharge port 130 is at the lowest position of the storage barrel 100. The liquid in the storage barrel 100 converges at the lowest position under the action of gravity. The silica gel raw material contained in the storage barrel 100 can be fully converged into the discharge port 130 and enter the cam pump 300 to be transported into the automatic dispensing arm, so that all the silica gel raw material contained in the storage barrel 100 can participate in the feeding cycle. At the same time, when changing materials and cleaning, the downwardly inclined and shrinking bottom end helps the cleaning liquid to clean the inner wall of the storage barrel 100, reduces the cleaning dead corners inside the storage barrel 100, and at the same time facilitates the complete discharge of the cleaning liquid, reduces cleaning residues, saves cleaning water, reduces the possibility of raw material pollution in the storage barrel 100, and prevents the mixing and pollution of the raw materials in the storage barrel 100 or caking during the material change operation, resulting in feeding blockage.

[0029] In one embodiment, the pipeline connecting the discharge port 130 and the cam pump 300 is a stainless steel pipeline. The stainless steel pipeline has good sealing effect, the stainless steel surface is smooth and not easy to rust, which is beneficial to reducing the possibility of raw material pollution during transportation. At the same time, the stainless steel pipeline has high strength, firm connection and long service life.

[0030] In one embodiment, the feed port is circular and is covered with an upper cover 110. The upper cover 110 closes the upper end of the storage barrel 100. Closing the feed port of the storage barrel 100 in this way simplifies the structure of the storage barrel 100. The upper cover 110 is convenient to install and disassemble, which is convenient for replenishing the raw materials in the storage barrel 100.

[0031] In one embodiment, the storage barrel 100 is also provided with a pressure port and a pressure gauge. A pressure valve is installed at the pressure port, and the pressure gauge is used for monitoring the pressure in the storage barrel 100. The pressure valve controls the intake of air into the storage barrel 100 to maintain the stability of the pressure in the storage barrel 100 and ensure the stability of the automatic feeding cycle. The pressure gauge monitors the inside of the storage barrel 100 in real time to ensure the smooth progress of automatic dispensing and can also timely detect pressure faults in the storage barrel 100. Thus, it is convenient to supervise whether the automatic feeding of the liquid silica gel raw material is carried out smoothly. The storage barrel 100 is also provided with a safety valve and an exhaust valve for adjusting the pressure in the storage barrel 100. If the pressure in the barrel continues to rise after reaching the set pressure, the safety valve opens to exhaust and relieve pressure, timely discharging the excess gas in the storage barrel 100 to prevent damage to the cam pump 300 or other components due to excessive pressure and improve the safety of production. The exhaust valve directly exhausts gas to ensure the balance of air pressure inside and outside the storage barrel 100 during the loading and replenishing of the storage barrel 100 and ensure the normal progress of loading and replenishing.

[0032] In one embodiment, the material of the storage barrel 100 is stainless steel, and the storage barrel 100 is welded to the fixed bracket 200. Stainless steel has high strength and does not react with the raw materials, and can store the raw materials well during production. Welding fixes the storage barrel 100 to the fixed bracket 200, making the fixation of the storage barrel 100 stable. The storage barrel 100 will not be violently shaken and toppled due to external impacts, which helps to ensure the safe progress of production and reduce the requirements for the production environment. At the same time, a stable storage environment helps to reduce the generation of bubbles in the liquid raw materials and improve the quality of the dispensed products.

[0033] In one embodiment, a plurality of feet 600 are provided at the bottom of the fixed bracket 200. The feet 600 support the fixed bracket 200, increasing the friction with the ground, so that the automatic feeding device for new energy silicone raw materials is not likely to move in position. The support feet can also be adjusted in height to ensure the horizontal placement of the body of the storage barrel 100 and reduce the requirements for the flatness of the ground in the production site.

[0034] In one embodiment, the feeding pipe 400 and the return pipe 500 are soft rubber hoses. To improve the automation of the dispensing operation, the automatic dispensing arm needs to move in the direction of the assembly line production. To ensure the free movement of the automatic dispensing arm, the feeding pipe 400 and the return pipe 500 should be made of soft materials, which can be bent as the automatic dispensing arm moves, without hindering the movement of the automatic dispensing arm and ensuring the continuous progress of automatic feeding.

[0035] In other embodiments, only the parts of the feeding pipe 400 and the return pipe 500 that protrude from the fixed bracket and are connected to the gantry can be made of soft rubber material to not hinder the movement of the automatic dispensing arm.

[0036] It should be understood that for those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of the present utility model.

[0037] The above describes the patent of the present utility model with reference to the accompanying drawings in an exemplary manner. Obviously, the implementation of the patent of the present utility model is not limited by the above methods. As long as various improvements are made by adopting the method concept and technical solution of the patent of the present utility model, or the concept and technical solution of the patent of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
