Description

Technical Field

[0001] The invention relates to the technical field of battery manufacturing, and in particular to a glue supply device with adjustable flow and pressure. Background Art

[0002] In the modern battery manufacturing industry, pole piece glue coating is a crucial process link, and its quality directly affects the performance, safety and service life of the battery. During the pole piece glue coating process, the uniform distribution and precise control of the glue liquid are the key to achieving high-quality coating. However, due to the diversity of battery design and the flexibility of production requirements, the pole piece glue coating process faces many challenges, among which the precise adjustment of the glue supply flow rate and the matching of the glue supply system pressure with the coating roller and scraper form are particularly prominent.

[0003] First of all, the glue supply flow rate of the electrode coating needs to be dynamically adjusted according to different blueprints (i.e. product design specifications or production requirements). Different blueprints often mean different requirements for parameters such as coating thickness, width, and uniformity. For example, a high-energy-density battery design may require a thicker coating to accommodate more active substances, while a fast-charging battery may require a thinner coating to reduce internal resistance. However, the existing glue supply system does not have a high degree of flexibility and accuracy, nor can it respond quickly and accurately adjust the glue supply flow rate to meet production needs under different blueprints.

[0004] Secondly, as the core components in the glue coating process, the form and design of the coating roller and scraper directly affect the distribution of the glue and the final quality of the coating. The material, surface texture, rotation speed of the coating roller, and the angle and position of the scraper will have a significant impact on the fluidity of the glue and the morphology of the coating. However, during the electrode coating process, the pressure of the existing glue supply system cannot be adjusted accordingly according to the specific form of the coating roller and scraper.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0035] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0036] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0037] See also Figure 1-5 The present embodiment discloses a glue supply device with adjustable flow rate and pressure, comprising: a glue supply body 1, a rotating shaft 2, a safety mechanism 3 and a rotating shaft driving member 4. The glue supply body 1 is provided with an inlet 5, a connecting channel 6 and an outlet 7 which are connected in sequence. The rotating shaft 2 is rotatably installed in the connecting channel 6. The driving end of the rotating shaft driving member 4 is transmission-connected with the rotating shaft 2 to drive the rotating shaft 2 to drive the liquid in the inlet 5 to the outlet 7. A safety circuit 8 which is connected with the inlet 5 and the outlet 7 is provided in the rotating shaft 2. The safety mechanism 3 is installed in the safety circuit 8 to open or close the safety circuit 8 according to the pressure of the liquid.

[0038] The glue supply system of this embodiment can adjust the glue supply flow rate according to different blueprints by adjusting the rotation speed of the rotating shaft 2, and can also control the pressure of the glue supply system by adjusting the pre-tightening pressure of the safety mechanism 3 to meet the needs of different glue supply pressures.

[0039] The working principle is as follows: when glue supply is required, the shaft driving member 4 is driven, the shaft driving member 4 drives the shaft 2 to rotate, and the rotation of the shaft 2 drives the liquid in the feed port 5 to the discharge port 7, thereby realizing glue supply.

[0040] The liquid may be fluid substances such as water, glue and oil.

[0041] In this embodiment, a spiral groove 9 is provided on the outer surface of the rotating shaft 2 , and two ends of the spiral groove 9 are respectively connected to the feed port 5 and the discharge port 7 .

[0042] Specifically, a spiral groove 9 is provided on the outer surface of one end of the rotating shaft 2 , and two ends of the spiral groove 9 are respectively connected to the feed port 5 and the discharge port 7 .

[0043] The design of the spiral groove 9 can guide the liquid to flow along the direction of the groove. This guiding effect helps the liquid to be transferred more smoothly from the inlet 5 to the outlet 7, reducing the accumulation and retention of liquid around the rotating shaft 2, thereby improving the overall liquid delivery efficiency.

[0044] In this embodiment, a plurality of rotating shafts 2 are provided, and each rotating shaft 2 is provided with a gear 10 (such as Figure 2 As shown), adjacent rotating shafts 2 are meshed through gears 10.

[0045] The gear 10 transmission usually has a high transmission efficiency, which is much higher than other transmission modes such as belt transmission and chain transmission. This high-efficiency transmission helps to reduce energy loss and improve the efficiency of the entire mechanical system. Multiple shafts 2 are meshed and connected through gears 10, which can realize complex transmission functions in a limited space and improve space utilization.

[0046] In this embodiment, the shaft 2 and the shaft driving member 4 are connected by a coupling 11 (such as Figure 2 As shown in Figure 1, the two shafts are connected by a transmission. Due to the impossibility of absolute precision in manufacturing and installation, as well as various deformation factors during operation, relative offset may occur between the two shafts. The coupling 11 has a certain ability to compensate for the offset between the two shafts, so as to eliminate or reduce the additional load caused by such offset and improve the transmission performance.

[0047] It should be noted that the shaft driving member 4 can be a motor.

[0048] In this embodiment, please refer to Figure 6 and Figure 7 The safety mechanism 3 includes: a base 12, an elastic member 13, a plug 14 and a safety component 15. The base 12 and the safety component 15 are installed in the safety circuit 8. A base through hole 16 is provided on the base 12, and a safety through hole 17 is provided on the safety component 15. The base through hole 16 and the safety through hole 17 are connected. One end of the elastic member 13 abuts against the base 12, and the other end of the elastic member 13 abuts against the plug 14 to abut the plug 14 on the safety through hole 17 and block the safety through hole 17.

[0049] The entire safety mechanism 3 is embedded in the front end of the rotating shaft 2, and the plug 14 seals the circuit under the elastic force of the elastic member 13 (such as a spring or a spring), when the pressure of the glue supply system exceeds the elastic force of the elastic member 13, the liquid will push the plug 14, thereby opening the safety circuit 8, and the liquid returns to the feed port 5 through the safety through hole 17, the base through hole 16 and the safety circuit 8 in turn, thereby ensuring that the pressure of the entire glue supply system will not be over-pressured.

[0050] The safety mechanism 3 is composed of several basic parts, including a base 12, an elastic member 13, a plug 14 and a safety member 15, and has a compact structure and is simple and clear. This design not only reduces the manufacturing cost, but also makes installation, commissioning and daily maintenance easier and faster. In addition, by adjusting the preload of the elastic member 13 and the size of the plug 14, the safety mechanism 3 can adapt to safety holes 17 of different sizes and safety requirements of different levels. This flexibility enables the mechanism to be widely used in various safety circuits 8 to meet the safety protection requirements in different scenarios.

[0051] The preload force of the elastic member 13 can be adjusted by rotating the base 12, thereby adjusting the elastic force of the elastic member 13. After the adjustment, the opening thrust of the plug 14 will change, thereby realizing the function of adjusting the glue supply pressure of the system.

[0052] Specifically, the base 12 is threadedly connected to the inner wall of the safety circuit 8, and the safety component 15 is threadedly connected to the inner wall of the safety circuit 8. The distance between the base 12 and the safety component 15 can be adjusted by rotating the base 12, so that the compression length of the elastic member 13 can be adjusted to adjust the elastic force of the elastic member 13, thereby realizing the function of adjusting the system glue supply pressure.

[0053] Of course, the distance between the base 12 and the safety component 15 can also be adjusted by rotating the safety component 15, so that the compression length of the elastic component 13 can be adjusted to adjust the elastic force of the elastic component 13, thereby realizing the function of adjusting the system glue supply pressure.

[0054] In some embodiments, the base 12 is mounted on the inner wall of the safety loop 8, the base 12 is threadedly connected to the safety member 15, and the distance between the base 12 and the safety member 15 is adjusted by rotating the safety member 15, so that the compression length of the elastic member 13 can be adjusted to adjust the elastic force of the elastic member 13, thereby realizing the function of adjusting the system glue supply pressure. Alternatively, the safety member 15 is mounted on the inner wall of the safety loop 8, the base 12 is threadedly connected to the safety member 15, and the distance between the base 12 and the safety member 15 is adjusted by rotating the base 12, so that the compression length of the elastic member 13 can be adjusted to adjust the elastic force of the elastic member 13, thereby realizing the function of adjusting the system glue supply pressure.

[0055] Through the threaded connection between the base 12 or the safety member 15 and the inner wall of the safety loop 8, the user can easily adjust the distance between the base 12 and the safety member 15 by rotating these components. This design allows fine adjustment of the compression length of the elastic member 13, thereby accurately controlling the elastic force of the elastic member 13. This high degree of adjustability enables the system to flexibly adjust the glue supply pressure according to different working requirements or environmental conditions, ensuring the stability and efficiency of the production process.

[0056] In this embodiment, please refer to Figure 6-8 A base limiting portion 18 is provided on the base 12, a plug limiting portion 19 is provided on the plug 14, and two ends of the elastic member 13 are respectively sleeved on the base limiting portion 18 and the plug limiting portion 19.

[0057] The arrangement of the base stopper 18 and the plug stopper 19 provides a clear installation location and support point for the elastic member 13. This design ensures that the elastic member 13 can be stably maintained at a predetermined position when subjected to external forces (such as pressure, vibration, etc.), and is not prone to displacement or falling off, thereby improving the stability and safety of the entire structure. In addition, by respectively sleeve-mounting the two ends of the elastic member 13 on the base stopper 18 and the plug stopper 19, the assembly process is simplified. This is not only easy to operate, but also reduces the number of parts and complex operating steps required for assembly, thereby improving production efficiency.

[0058] In this embodiment, please refer to Figure 2-9 , and also includes: a sealing body 20 and a sealing member 21. The sealing body 20 is connected to the glue supply body 1. A sealing channel 22 and a sliding groove 23 connected to the sealing channel 22 are arranged in the sealing body 20. The sealing member 21 is slidably installed in the sliding groove 23. A sealing block 24 located at one end of the sliding groove 23 is arranged on the rotating shaft 2. When the sealing member 21 slides to abut against the sealing block 24, the rotating shaft 2 is sealed.

[0059] When the sealing channel 22 is filled with gas or liquid, the sealing member 21 moves toward the sealing block 24 under the push of the gas or liquid, and slides until it abuts against the sealing block 24, thereby achieving sealing of the rotating shaft 2.

[0060] The seal 21 can slide in the sliding groove 23 and form a dynamic seal with the sealing block 24 on the rotating shaft 2. When the seal 21 slides to tightly abut against the sealing block 24, it can effectively prevent the medium from leaking through the gap between the rotating shaft 2 and the sealing body 20, achieving an efficient sealing effect.

[0061] The seal 21 is provided with a wear-resistant part 25 (such as Fig.10 As shown), the wear-resistant part 25 is usually made of wear-resistant and corrosion-resistant materials, such as rubber, polytetrafluoroethylene, etc. These materials have good wear resistance and corrosion resistance, and can maintain a stable sealing effect for a long time in a harsh working environment.

[0062] Furthermore, a guide rod 26 (such as Fig.10 As shown), the guide rod 26 is slidably installed in the sealing channel 22.

[0063] The sliding installation of the guide rod 26 in the sealing channel 22 provides accurate positioning and guidance for the seal 21. This helps to ensure that the seal 21 always remains in the correct position during operation, avoiding seal failure caused by deviation or misalignment. At the same time, the matching design of the guide rod 26 and the sealing channel 22 simplifies the installation process of the seal 21. The installer can more easily position and fix the seal 21 in the correct position without complicated adjustment or calibration.

[0064] Furthermore, a sealing ring 27 (such as Fig.10 shown).

[0065] The main function of the sealing ring 27 is to provide a sealing effect to prevent liquid, gas or other media from leaking from the gap between the guide rod 26 and the sealing surface. This design ensures the sealing of the structure.

[0066] In this embodiment, please refer to Figure 2-12 , further comprising: a reversing member 28 and a reversing driving member 29, the reversing driving member 29 being mounted on the glue supply body 1, a feeding through hole 30 and a circulation through hole 31 being arranged on the end of the connecting channel 6 close to the discharge port 7, a reversing channel 32 and a circulation channel 33 being arranged on the glue supply body 1, the feeding through hole 30, the circulation through hole 31, the discharge port 7 and the circulation channel 33 being all connected to the reversing channel 32, the circulation through hole 31 being arranged between the feeding through hole 30 and the circulation channel 33, The reversing member 28 is movably installed in the reversing channel 32. The driving end of the reversing driving member 29 is transmission-connected to one end of the reversing member 28 to drive the reversing member 28 to move and seal the feeding through hole 30 or the circulation through hole 31. When the feeding through hole 30 is sealed, the circulation through hole 31 is connected to the circulation channel 33, and the feeding through hole 30 is not connected to the discharge port 7. When the circulation through hole 31 is sealed, the feeding through hole 30 is connected to the discharge port 7, and the circulation through hole 31 is not connected to the circulation channel 33.

[0067] When the device circulates, the reversing drive 29 drives the reversing member 28 to move. When the reversing member 28 moves to the feeding through hole 30 and seals the feeding through hole 30, since the circulation through hole 31 is connected with the circulation channel 33, the feeding through hole 30 is not connected with the discharge port 7, the circulation line is opened, and the liquid will flow from the circulation through hole 31 and the circulation channel 33 to the feed port 5, and circulate inside the glue supply mechanism, which can effectively prevent the glue from solidifying.

[0068] When the device is feeding, the reversing drive 29 drives the reversing member 28 to move. When the reversing member 28 moves to the circulation through hole 31 and seals the circulation through hole 31, since the feeding through hole 30 is connected with the discharge port 7, the circulation through hole 31 is not connected with the circulation channel 33, the feeding line is opened, and the glue feeding mechanism feeds normally.

[0069] Furthermore, the reversing member 28 is provided with a sealing portion 34 (such as Fig.13 shown).

[0070] The diameter of the sealing portion 34 is similar to that of the reversing channel 32, so that the sealing portion 34 can seal the reversing channel 32. When the sealing portion 34 moves to the circulation through hole 31, the sealing portion 34 seals the part of the reversing channel 32 connected to the circulation through hole 31, so that the circulation through hole 31 is also sealed. The sealing principle of the feed through hole 30 is similar and will not be described in detail. Both ends of the sealing portion 34 are grooves, so there is a gap between the groove and the reversing channel 32, and the liquid can flow out from there.

[0071] In this embodiment, both ends of the reversing member 28 are provided with reversing seals 35 (such as Fig.13 shown).

[0072] Reversing seals 35 are provided at both ends of the reversing member 28 to ensure that the liquid in the reversing channel 32 will not leak during the movement of the reversing member 28, thereby ensuring the sealing and safety during the reversing process.

[0073] In this embodiment, it also includes: a reset member 36 (such as Fig.12 As shown), one end of the reset member 36 is connected to the glue supply body 1, and the other end of the reset member 36 is connected to the other end of the reversing member 28.

[0074] Among them, the reset member 36 can have two states, one is compression and the other is tension, and the two states have two different reset modes. When the reset member 36 is in the compressed state, the reversing drive member 29 drives the reversing member 28 to move up to seal the circulation through hole 31, and the reset member 36 is compressed. At this time, the feeding through hole 30 is connected with the discharge port 7, and the circulation through hole 31 is not connected with the circulation channel 33. When the reversing drive member 29 stops driving, the reset member 36 returns to its original state, and the reversing member 28 gradually moves down and moves to the feeding through hole 30 under the action of the elastic force of the reset member 36 to seal the feeding through hole 30. At this time, the circulation through hole 31 is connected with the circulation channel 33, and the feeding through hole 30 is not connected with the discharge port 7.

[0075] When the reset member 36 is in the stretched state, the reversing driving member 29 drives the reversing member 28 to move downward to seal the feed hole 30, and the reset member 36 is stretched. At this time, the circulation hole 31 is connected with the circulation channel 33, and the feed hole 30 is not connected with the discharge port 7. When the reversing driving member 29 stops driving, the reset member 36 returns to its original state, and the reversing member 28 gradually moves upward and moves to the circulation hole 31 under the elastic force of the reset member 36 to seal the circulation hole 31. At this time, the feed hole 30 is connected with the discharge port 7, and the circulation hole 31 is not connected with the circulation channel 33.

[0076] The reset element 36 may be a spring, compressed gas, or a structure that can be reset by gas.

[0077] In this embodiment, it also includes: a cap 37 (such as Fig.12 As shown), the cap 37 is detachably installed in the reversing channel 32, one end of the reset member 36 is connected to the cap 37, and the other end of the reset member 36 is connected to the other end of the reversing member 28.

[0078] The detachable design of the cap 37 allows the cap 37 to be easily removed when the reversing channel 32 needs to be maintained or cleaned, without the need to perform complex disassembly of the entire structure, which greatly reduces the difficulty and time cost of maintenance.

[0079] In this embodiment, the reversing drive member 29 is connected to the fixed plate 38 (such as Figure 2 As shown) is installed on the glue supply body 1.

[0080] The reversing drive member 29 is mounted on the glue supply body 1 through the fixing plate 38, which can ensure that the reversing drive member 29 maintains a stable position and posture during operation, reducing displacement or loosening caused by vibration or impact. This stable installation method helps to improve the overall stability and reliability of the device.

[0081] It should be noted that the reversing drive element 29 may be a cylinder, a hydraulic drive element, or other linear drive devices.

[0082] In this embodiment, it also includes: a glue barrel 39 (such as Figure 1 As shown), a glue barrel 39 is installed on the glue supply body 1, and a liquid containing chamber for containing liquid and a glue barrel injection port 40 for injecting material are provided in the glue barrel 39, and the glue barrel injection port 40, the liquid containing chamber and the feed port 5 are connected in sequence.

[0083] The glue barrel 39 is directly mounted on the glue supply body 1, reducing intermediate connecting parts and pipelines, making the entire glue supply system compact and occupying less space. This integrated design not only facilitates the layout and installation of the equipment, but also helps to improve the space utilization of the production workshop.

[0084] In this embodiment, it also includes: a discharge joint 41 and a right angle joint 42 (such as Figure 2 As shown), the discharge joint 41 is installed on the discharge port 7, and the right-angle joint 42 is installed on the sealing channel 22.

[0085] The discharge connector 41 is installed on the discharge port 7. Through precise matching and possible sealing elements (such as the sealing ring 27), it can effectively prevent leakage of materials during the transmission process and ensure the sealing of the system. The right-angle connector 42 is installed on the sealing channel 22, which can reduce the additional space required for the traditional elbow.

[0086] In this embodiment, the bearing 43 and the bearing cover 44 (such as Figure 2 As shown), the bearing cover 44 is installed on the sealing body 20, the bearing 43 is arranged between the bearing cover 44 and the sealing body 20, and the rotating shaft 2 is rotatably installed on the bearing 43.

[0087] As a key supporting component of the rotating shaft 2, the bearing 43 provides precise and stable support for the rotating shaft 2 through the rolling of its internal rolling elements between the inner and outer rings. This support method reduces the friction and vibration of the rotating shaft 2 during rotation and ensures the smooth operation of the equipment. The bearing cover 44 is installed on the sealing body 20 and together with the bearing 43 forms a relatively closed environment. This design effectively prevents external dust, moisture and other contaminants from entering the interior of the bearing 43, thereby protecting the lubrication system and rolling elements of the bearing 43 and extending the service life of the bearing 43.

[0088] In this embodiment, a transmission cover 45 (such as Figure 2 As shown), the gear 10 is installed in the transmission cover 45, and the transmission cover 45 is connected to the sealing body 20.

[0089] The design of the transmission cover 45 effectively seals the gear 10 and the transmission system inside, preventing dust, dirt and other impurities from entering. This not only reduces the wear and corrosion of the gear 10, but also ensures the cleanliness of the transmission system and prolongs its service life.

[0090] In this embodiment, the pressure ring 46 and the locking nut 47 (such as Figure 2 As shown), the locking nut 47 is installed on the rotating shaft 2, and the pressure ring 46 is sleeved on the rotating shaft 2 and arranged between the locking nut 47 and the bearing 43.

[0091] When the locking nut 47 is tightened, the pressure ring 46 is deformed by the extrusion force, and this deformation enables the pressure ring 46 to fit tightly between the bearing 43 and the rotating shaft 2, forming a reliable sealing layer. This not only effectively prevents foreign impurities and pollutants from entering the bearing 43, but also prevents the leakage of liquid in the glue supply system, thereby ensuring the normal operation of the glue supply system and extending its service life.
