[0014] The utility model will be further explained in connection with specific embodiments. It should be understood that the following embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model.

[0015] Embodiment 1

[0016] Figure 1 It is a structure schematic view of the utility model. Figure 2 It is a structure schematic view of the buffer tank.

[0017] As Figure 1 Indicated, a kind of lithium battery adhesive feeding structure, comprising: storage tank 100, radar material level meter 200, diaphragm valve 300, buffer tank 400, rotor pump 500, flow meter 600 and industrial computer 700, storage tank 100 is connected with material bin, storage tank 100 is connected with buffer tank 400 by diaphragm valve 300, radar material level meter 200 is located in storage tank 100 and buffer tank 400, rotor pump 500 is connected with buffer tank 400, rotor pump 500 is connected with flow meter 600 by pipeline, flow meter 600 is connected with industrial computer 700.

[0018] As Figure 2 Indicated, wherein, buffer tank 400 includes: tank body 410, partition plate 420, downward pressure transmission motor 430, stirring structure 440 and heating inner wall 450, the top of tank body 410 is equipped with downward pressure transmission motor 430, downward pressure transmission motor 430 is connected with partition plate 420 by connecting shaft, stirring structure 440 is connected with the side end of tank body 410, heating inner wall 450 is located in tank body 410, heating inner wall 450 is connected with circulating water tank, partition plate 420 is equipped with discharge gate, the connecting place of the connecting shaft of downward pressure transmission motor 430 and tank body 410 is equipped with sealing element.

[0019] The principle of the utility model is: to cope with the challenge of material flow span, adopt upper and lower structure design. Upper storage tank 100 is fixed by support, realizes material descending by using the weight of material. Radar material level meter 200 is installed in storage tank, is responsible for monitoring liquid level and sends high-low limit alarm signal, to control the opening and closing of diaphragm valve 300, realizes accurate material addition.

[0020] The material enters the buffer tank 400 through the diaphragm valve 300, and from the buffer tank 400, the material is transported by the rotor pump 500. The inlet of the rotor pump is designed to be thickened to meet the flow requirements of high viscosity materials. The material flows through the flow meter 600, which provides real-time flow data for comparison with the set value. The industrial computer 700 receives the data from the flow meter, calculates the error through the PID control algorithm, and dynamically adjusts the speed of the rotor pump 500 to ensure the accuracy of the material injection and the stability of the system. When the pressure in the buffer tank 400 changes, the industrial computer 700 will automatically adjust the motor speed to maintain the stability of the output. Through this closed-loop control, the system realizes accurate transportation and metering of high-viscosity materials.

[0021] The radar level gauge 200 is designed to meet the high precision requirements of lithium battery adhesive. Lithium battery adhesive has high viscosity and stickiness, and non-contact radar level gauge avoids contamination and wear of the sensor by the material. At the same time, considering the corrosion problem, the design of the radar level gauge can avoid direct contact and prolong the service life of the equipment. The diaphragm valve 300 is also designed for the high precision requirements of lithium battery adhesive. The rotor pump 500 is designed not only for the high precision requirements of lithium battery adhesive, but also for the stability and transmission efficiency of high viscosity materials.

[0022] The overall improvement of the utility model improves the structure of the traditional chemical adding method, adopts the control of the buffer tank 400 cooperating with the diaphragm valve 300, the rotor pump 500, the flow meter 600 and the industrial computer 700, realizes more accurate, and guarantees the feeding accuracy of high viscosity adhesive.

[0023] On the other hand, for the characteristics of lithium battery adhesive, we are not limited to the traditional buffer tank 400. Through the improvement of the buffer tank 400, a more targeted design for lithium battery adhesive is realized.

[0024] The utility model adds three new structure combinations in the tank body, the baffle 420 and the lower pressure transmission motor 430 form the hydraulic control, realize the structure of adjusting and controlling the tank volume; the stirring structure 440 increases the flowability of the adhesive; the heating inner wall 450 controls the viscosity by stabilizing. The characteristics of lithium battery adhesive are high viscosity: lithium battery adhesive has high viscosity, which makes it need special equipment to ensure flowability and uniformity during transportation and mixing. High uniformity requirement: the adhesive needs to form a uniform coating in the battery assembly to ensure the performance and life of the battery. Sensitive chemical properties: its composition is sensitive to temperature, humidity or shear force, so it needs to be handled carefully to prevent degradation or reaction. Stability: the adhesive needs to remain stable during storage and use to prevent delamination or sedimentation.

[0025] The combination of the partition 420 and the downward pressure transmission motor 430 works as follows: the downward pressure transmission motor 430 drives the partition 420 to reduce the volume of the tank 410.

[0026] By reducing the volume of the tank 410, although it cannot directly affect the viscosity of the adhesive, it can indirectly affect the operations related to viscosity, first of all, it changes the mixing efficiency: with the cooperation of the stirring structure 440, under the premise of reducing the volume, it can make the non-professional stirring structure effectively act on the adhesive, reduce the dead zone, and improve the mixing uniformity. On the other hand, cooperating with the heating inner wall 450 to increase the heat exchange efficiency: reducing the volume can improve the heating or cooling efficiency, shorten the heat transfer path, and faster reach the required temperature. At the same time, it is also conducive to temperature control: it is easier to achieve uniform temperature distribution, thereby improving the viscosity management. Finally, in terms of pressure and flow, it is easier to control the flow after reducing the volume, thereby helping to handle high-viscosity materials.

[0027] The increase of the stirring structure 440 prevents sedimentation: the stirring structure can prevent the solid components in the high-viscosity adhesive from settling, ensuring that the adhesive in the entire tank remains uniform. Uniform mixing: continuous stirring helps to maintain uniform distribution of components and avoid stratification. Improve flowability: stirring can reduce the apparent viscosity of the adhesive and improve its flowability, making it easier to transport and use later. Improve pumping efficiency: uniform mixtures are easier to transport through pipes and pumps, improving production efficiency. Prevent bubble formation: appropriate stirring speed can help reduce bubble formation in the adhesive, ensuring the quality of the final product. The stirring structure 440 referred to in the utility model is a complete system including a motor, a stirring shaft, and stirring blades. Since it is directly purchased without any improvement, it will not be described.

[0028] The increase of the heating inner wall 450 can prevent sensitive components in the adhesive from degrading at high temperatures through precise temperature control, thereby maintaining the chemical properties of the material. Temperature regulation can help control the chemical reaction rate inside the adhesive, ensuring that it reaches the required performance within the appropriate time.

[0029] In summary, we have added more targeted functions to the buffer tank to control the flowability of the adhesive through flexible adjustment.

[0030] Compared with the traditional technology, the utility model improves the traditional feeding structure for the problems of lithium battery adhesive in the feeding process, adopts more suitable accessories for lithium battery adhesive for the external basic equipment, controls in the way of browser cooperating with the buffer tank, improves the buffer tank by controlling the volume to indirectly improve the viscosity problem.

[0031] The specific embodiments of the present application are described above, but the present application is not limited thereto, and various changes can be made to the present application without departing from the spirit of the present application.
