Description

Technical Field

[0001] This invention relates to the field of adhesive coating equipment technology, and in particular to a robotic adhesive coating equipment for the production of new energy vehicles. Background Technology

[0002] In the field of new energy vehicle manufacturing, the adhesive coating process for key components such as battery packs and high-voltage parts requires extremely high standards of sealing, durability, and process stability. Traditional adhesive coating equipment often uses air pressurization to drive the adhesive output. However, oxygen in the air easily reacts with polyurethane, silicone, and other adhesives, leading to accelerated curing, reduced bond strength, and decreased weather resistance, directly affecting the airtightness of the battery pack and the insulation performance of high-voltage components. Furthermore, air pressurization requires an oxygen generator, air compressor, and multi-stage filtration system, resulting in high equipment costs and complex maintenance. During pressurization, impurities such as moisture and oil can easily mix into the adhesive, causing coating defects and necessitating the addition of a precision filtration system, further increasing equipment complexity and manufacturing costs.

[0003] Meanwhile, the existing rubber rings on glue bucket sealing caps mostly adopt a protruding design, which easily causes severe friction with the inner wall of the glue bucket during the lifting and lowering of the cap, resulting in severe wear or even breakage of the seal, affecting the normal use of the glue coating equipment, and making replacement troublesome. Furthermore, due to the inherent limitations of traditional rubber rings, traditional equipment requires manual segmented pressure release and cap lifting when changing buckets, which is cumbersome and time-consuming. At the same time, glue tends to adhere to the outer wall of the glue suction conduit and the lower end surface of the traditional cap, requiring cleaning to prevent contamination of new glue and hindering the efficient operation of the production line. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a robotic adhesive application device for new energy vehicle production to solve the aforementioned problems.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a robotic glue-applying device for new energy vehicle production, comprising an intelligent glue applicator, a cover, and a nitrogen tank. A detachable glue bucket is mounted on the upper end of the intelligent glue applicator. The cover is adapted to the glue bucket. A glue-suction conduit is slidably connected through the middle of the lower end of the cover. An upper sealing cover is fixedly mounted on the lower end of the cover. A lower sealing cover is fixedly sleeved on the outer side of the glue-suction conduit near the upper side. Both the lower and upper sealing covers have [missing information - likely related to a specific feature or design]. An annular groove is provided, and a trapezoidal rubber ring is fitted inside the annular groove. An exhaust check valve is installed on the right side of the lower sealing cover, and an inlet check valve is installed on the left side of the lower sealing cover. A pressure reducing valve is connected to and fixedly installed at the exhaust port of the upper end of the nitrogen tank. A pressure regulating valve is connected to and fixedly installed at the front side of the pressure reducing valve. An inlet pipe is provided between the front nozzle of the pressure regulating valve and the inlet check valve. An exhaust valve is provided at the rear side of the upper end of the cover, and the lower end of the exhaust valve penetrates into the interior of the upper sealing cover.

[0006] Furthermore, a sleeve arranged in a circular array is fixedly installed on the upper end of the lower sealing cover, and a slide rod arranged in a circular array is fixedly installed on the lower end of the upper sealing cover, with the lower end of the slide rod penetrating and slidably connected inside the sleeve.

[0007] Furthermore, the nitrogen tank is detachably installed on the upper part of the intelligent glue applicator near the left rear end. A small oil-free vacuum pump is also fixedly installed on the upper part of the intelligent glue applicator on the right side of the nitrogen tank. A recovery hose is installed between the right input end of the small oil-free vacuum pump and the exhaust valve. A recovery rigid pipe is installed between the left output end of the small oil-free vacuum pump and the nitrogen tank.

[0008] Furthermore, a sintered metal filter element is installed on the recycling hose, and quick connectors are provided at both ends of the sintered metal filter element. The sintered metal filter element is connected to the recycling hose through the quick connectors, and a leak-proof one-way valve is installed on the recycling hose.

[0009] Furthermore, a baffle is slidably sleeved on the outer side of the adhesive suction conduit at the lower side of the lower sealing cover. The lower ends of the air outlet one-way valve and the air inlet one-way valve are both fixedly connected to a through pipe. The lower ends of the through pipes all penetrate the baffle. A silicone retaining ring is sleeved on the outer side of the through pipe at the lower end of the baffle. The outer ring of the baffle is in contact with the inner wall of the adhesive bucket.

[0010] Furthermore, a lifting frame is installed at the upper end of the intelligent glue applicator with the glue bucket as the center. A cylinder is fixedly installed at the lower middle position of the top plate of the lifting frame. The lower telescopic end of the cylinder is fixedly connected to the upper middle position of the cover.

[0011] Furthermore, the cover is provided with a glue discharge valve at the upper front position, and a glue delivery head is provided at the middle position of the upper end of the cover. Both the glue delivery head and the glue discharge valve are connected to the glue suction conduit in the inner cavity of the cover.

[0012] (III) Beneficial Effects This invention provides a robotic adhesive application device for new energy vehicle production. It has the following advantages: This equipment uses nitrogen instead of air for pressurized adhesive supply. Nitrogen is chemically stable and will not react with polyurethane, silicone, or other components in the adhesive. This fundamentally avoids problems such as accelerated oxidation and curing and decreased adhesion caused by contact with oxygen. Furthermore, nitrogen is dry and clean, free of moisture and oil, eliminating the need for filtration and preventing impurities from contaminating the adhesive. This effectively reduces pipe and nozzle blockage and is suitable for high-quality adhesive application requirements in new energy vehicle battery packs, high-voltage components, and other applications.

[0013] The trapezoidal rubber ring expands outward under nitrogen pressure, forming a full compression contact with the inner wall of the glue tank to achieve self-adaptive sealing. The sealing effect is good and it can effectively maintain the stability of the pressure inside the tank. With the linkage control of the pressure regulating valve and pressure sensor, the pressure can be automatically replenished when the glue material decreases, ensuring a uniform glue output speed and avoiding problems such as glue breakage and uneven glue lines, further ensuring the consistency of the glue coating process.

[0014] The trapezoidal rubber ring achieves sealing by self-expanding under nitrogen pressure. After depressurization and recovery, the rubber ring automatically returns to its fitted state. During the lifting and lowering of the cover, the friction between the rubber ring and the inner wall of the glue tank is minimal. Compared with the traditional protruding rigid sealing design, this avoids problems such as excessive wear and breakage of the rubber ring. At the same time, the cover can be quickly and stably lifted and lowered by a cylinder without cumbersome manual operation. The baffle design can quickly scrape off the glue material adhering to the outer wall of the glue suction tube, and the baffle can be quickly disassembled for cleaning and replacement, reducing glue cleaning and equipment debugging time, significantly improving the efficiency of changing the glue tank, and reducing the interruption time of the glue coating process.

[0015] The glue is supplied by utilizing the natural pressure difference between the high-pressure nitrogen in the nitrogen tank and the working pressure of the glue bucket. There is no need to configure additional equipment such as oxygen generator, air compressor, and booster pump, which reduces the initial investment. At the same time, the nitrogen is filtered by a metal sintered filter and then recycled back to the nitrogen tank for reuse. The filter can be backflushed and regenerated for reuse, reducing nitrogen consumption and consumable replacement costs. The long-term operation is economically significant.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0019] Please see Figures 1-6This invention provides a robotic glue-applying device for new energy vehicle production, including an intelligent glue applicator 1, a cover 3, and a nitrogen tank 4. A detachable glue tank 2 is mounted on the upper end of the intelligent glue applicator 1. The cover 3 is adapted to the glue tank 2. A glue-suction conduit 31 is slidably connected through the middle of the lower end of the cover 3. An upper sealing cover 32 is fixedly mounted on the lower end of the cover 3. A lower sealing cover 33 is fixedly sleeved on the outer side of the glue-suction conduit 31 near the upper side. Both the lower sealing cover 33 and the upper sealing cover 32 have annular grooves 34 near their edges at their adjacent ends. A trapezoidal rubber ring 35 is fitted inside the annular grooves 34. A [missing information - likely a device or material] is mounted on the right side of the lower sealing cover 33. An exhaust check valve 38 is installed on the lower sealing cover 33 on the left side. An intake check valve 39 is installed on the upper exhaust port of the nitrogen tank 4. A pressure reducing valve 41 is connected to and fixedly installed on the front side of the pressure reducing valve 41. An intake pipe 43 is provided between the front nozzle of the pressure reducing valve 42 and the intake check valve 39. An exhaust valve 5 is provided on the rear side of the upper end of the cover 3. The lower end of the exhaust valve 5 penetrates into the interior of the upper sealing cover 32. A glue discharge valve 9 is provided on the front side of the upper end of the cover 3. A glue delivery head 10 is provided on the middle position of the upper end of the cover 3. Both the glue delivery head 10 and the glue discharge valve 9 are connected to the glue suction conduit 31 in the inner cavity of the cover 3. When replacing the glue container 2, keep it aligned with the cover 3. Open cylinder 81 to lower the cover 3 and other structures, simultaneously opening the exhaust valve 5. At this point, the trapezoidal rubber ring 35 is only in contact with the inner wall of the glue container 2. Before lowering, the outer side of the trapezoidal rubber ring 35 is coated with grease or other lubricant, resulting in minimal friction. This allows the cover 3 to quickly descend to the liquid level of the glue in the glue container 2. During this process, air inside the glue container 2 is expelled through the one-way valve 38, the exhaust valve 5, or edge gaps. The high-pressure nitrogen is precisely reduced to a level slightly higher than the set pressure of the glue container 2 by opening the pressure reducing valve 41. Then, the nitrogen is further regulated by the pressure regulating valve 42. The pressure is reduced, allowing nitrogen to enter the glue container 2 at a low and continuous flow rate through the inlet pipe 43 and the inlet check valve 39. This allows the nitrogen to fill and displace the air on the upper side of the glue in the container 2. The replacement time is adjusted according to the solvent in the glue container 2; for example, a 20-liter glue container 2 requires approximately 40 seconds. After the internal air is expelled, the exhaust valve 5 is closed. Then, the nitrogen pressure is increased to the working pressure of the glue container 2 through the pressure regulating valve 42. As the nitrogen increases, the sealed space formed by the upper sealing cap 32, the lower sealing cap 33, and the trapezoidal rubber ring 35 is also pressurized. This nitrogen pressure causes the trapezoidal rubber ring 35 to expand outward, thereby allowing the trapezoidal rubber ring 35 to... The inner walls of the glue tank 2 achieve sufficient compression contact, resulting in an adaptive sealing treatment with good sealing effect, thus maintaining stable pressure. When the working pressure inside the glue tank 2 is reached, the glue is continuously output through the suction conduit 31. As the amount of glue in the glue tank 2 decreases, the volume increases, and the pressure drops slightly. At this time, the pressure regulating valve 42 automatically replenishes the pressure to ensure stable pressure and uniform glue output speed. Furthermore, when the suction conduit 31 outputs the glue upward and overflows through the discharge valve 9, the discharge valve 9 is closed in time. At the same time, the glue is transported to the glue head integrated on the robotic arm through the glue delivery pipe connected to the glue delivery head 10. Compared to... The current adhesive application equipment uses nitrogen to expel air and pressurize the adhesive instead of air. This prevents the nitrogen from reacting with polyurethane and silicone in the adhesive, thus effectively preventing oxidation, accelerated curing, and decreased adhesion caused by contact with oxygen. In addition, nitrogen is dry and clean, free of moisture and oil, eliminating the need for complex filtration. Furthermore, the nitrogen in nitrogen tank 4 is under high pressure, creating a significant pressure difference with the working pressure in adhesive tank 2. Compared to traditional air pressurization, this saves on investment in oxygen generators and pressurization pumps, while meeting the high-quality adhesive application requirements for battery packs and high-voltage components in new energy vehicle production.

[0020] Please see Figure 6The upper end of the lower sealing cover 33 is fixedly installed with sleeves 36 arranged in a circular array, and the lower end of the upper sealing cover 32 is fixedly installed with slide rods 37 arranged in a circular array. The lower end of the slide rods 37 passes through and slides inside the sleeves 36. The upper sealing cover 32 and the lower sealing cover 33 of this device are designed to be separate. Therefore, the sliding design of the sleeves 36 and the slide rods 37 improves the structural stability and ensures the rationality of the structural design.

[0021] Please see Figures 2-6 Nitrogen tank 4 is detachably installed on the upper end of intelligent glue applicator 1 near the left rear end. A small oil-free vacuum pump 6 is also fixedly installed on the upper end of intelligent glue applicator 1 on the right side of nitrogen tank 4. A recovery hose is installed between the right input end of small oil-free vacuum pump 6 and exhaust valve 5. A recovery rigid pipe is installed between the left output end of small oil-free vacuum pump 6 and nitrogen tank 4. A metal sintered filter element 61 is installed on the recovery hose. Quick connectors are installed at both ends of metal sintered filter element 61. Metal sintered filter element 61 is connected to the recovery hose through quick connectors. A leak-proof one-way valve 62 is installed on the recovery rigid pipe. When it is necessary to change the container or shut down the machine, close the pressure reducing valve 41 and the pressure regulating valve 42. At the same time, insert the other end of the recovery hose on the small oil-free vacuum pump 6 into the exhaust valve 5, and open the switches of the small oil-free vacuum pump 6 and the exhaust valve 5 to extract the nitrogen from the glue container 2. The nitrogen will then be filtered through the metal sintered filter element 61 to remove any trace amounts of glue mist that may be present in the nitrogen. Finally, the nitrogen will be recovered back into the nitrogen tank 4. The metal sintered filter element 61 should be removed periodically for backflushing and regeneration cleaning to ensure long-term use and reduce operating costs. In addition, the flow... After the nitrogen gas is recovered, the internal pressure of the upper sealing cover 32, the lower sealing cover 33, and the trapezoidal rubber ring 35 will return to atmospheric pressure. The trapezoidal rubber ring 35 will no longer be compressed and expanded by the nitrogen gas pressure, thus restoring its state of being close to or in contact with the inner wall of the rubber barrel 2. Therefore, when the cover body 3 is lifted by opening the cylinder 81, it can continue to rise stably. Compared with the traditional protruding design, there will be no greater wear or even breakage. At the same time, compared with the traditional manual segmented lifting method, the lifting efficiency of the cover body 3 is greatly improved.

[0022] Please see Figures 4-6A baffle 7 is slidably sleeved on the outside of the glue suction tube 31 at the lower side of the lower sealing cover 33. The lower ends of the air outlet check valve 38 and the air inlet check valve 39 are both fixedly connected to the through pipe 71. The lower ends of the through pipe 71 pass through the baffle 7. The outside of the through pipe 71 is sleeved with a silicone retaining ring 72 at the lower end of the baffle 7. The outer ring of the baffle 7 is in contact with the inner wall of the glue bucket 2. The upper end of the intelligent glue applicator 1 is equipped with a lifting frame 8 centered on the glue bucket 2. The top plate of the lifting frame 8 is fixedly installed with a cylinder 81 at the lower middle position. The lower telescopic end of the cylinder 81 is fixedly connected to the upper middle position of the cover 3. After the cover 3 rises and detaches from the glue tank 2, the baffle 7 can slide downwards directly. During this process, the glue material adhering to the outer wall of the glue suction tube 31 is scraped off. After removing the baffle 7, it can be cleaned, and the glue replacement efficiency can be improved by replacing it with a new one. The silicone retaining ring 72 is fitted onto the lower end of the tube 71 to provide support for the baffle 7 and also to seal it. The design of the baffle 7 can also effectively shield structures such as the lower sealing cover 33, reducing the adhesion of glue material, thereby reducing the cleaning work and further reducing the time required to replace the glue tank 2. This improves the glue application efficiency of the glue head on the robotic arm for new energy vehicle battery packs and high-voltage components.

[0023] Working principle: When replacing the glue bucket 2, keep it aligned with the cover 3. Opening cylinder 81 lowers the cover 3 and other structures, simultaneously opening the exhaust valve 5. At this point, the trapezoidal rubber ring 35 is only in contact with the inner wall of the glue bucket 2. Before lowering, the outer side of the trapezoidal rubber ring 35 is coated with grease or other lubricant, resulting in minimal friction. This allows the cover 3 to quickly descend to the liquid level of the glue in the glue bucket 2. During this process, air inside the glue bucket 2 is expelled through the exhaust valve 38 and the exhaust valve 5, or through edge gaps. The high-pressure nitrogen is precisely reduced to a range slightly higher than the set pressure of the glue bucket 2 by opening the pressure reducing valve 41. Then, the nitrogen pressure is further reduced by the pressure regulating valve 42, allowing nitrogen to flow continuously through the inlet pipe 43 and the inlet valve at a low flow rate. Valve 39 enters the interior of the glue container 2, allowing nitrogen gas to fill and compress the air on the upper side of the glue material inside the container 2. The replacement time is adjusted according to the solvent in the glue container 2; for example, a 20-liter glue container 2 requires approximately 40 seconds. After the internal air is expelled, the exhaust valve 5 is closed. Then, the nitrogen pressure is increased to the working pressure of the glue container 2 through the pressure regulating valve 42. As the nitrogen gas increases, the sealed space formed by the upper sealing cover 32, the lower sealing cover 33, and the trapezoidal rubber ring 35 is also pressurized. The nitrogen pressure causes the trapezoidal rubber ring 35 to expand outward, thereby achieving sufficient compression contact between the trapezoidal rubber ring 35 and the inner wall of the glue container 2, achieving adaptive sealing treatment with good sealing effect. This maintains stable pressure, and when the working pressure inside the glue container 2 is reached, the glue material is compressed by the pressure. As the adhesive is continuously output through the suction conduit 31, the volume of the adhesive in the adhesive tank 2 increases due to the decrease in adhesive content, causing a slight drop in pressure. At this time, the pressure regulating valve 42 automatically replenishes the pressure to ensure stable pressure and uniform adhesive output speed. Furthermore, when the adhesive is output upward through the suction conduit 31 and overflows through the discharge valve 9, the discharge valve 9 is closed in time. At the same time, the adhesive is delivered to the adhesive head integrated on the robotic arm through the adhesive delivery pipe connected to the dispensing head 10. Compared with current adhesive application devices, this equipment uses nitrogen to expel air and pressurize the adhesive by replacing air with nitrogen. It will not react with polyurethane and silicone in the adhesive, effectively preventing the adhesive from oxidizing due to contact with oxygen, accelerating the curing speed, and reducing the bonding performance. In addition, nitrogen is dry and clean, and itself... Free from moisture and oil, requiring no additional complex filtration, and with nitrogen in nitrogen tank 4 already at high pressure, creating a significant pressure difference with the working pressure in glue container 2, this saves on investment in oxygen generators and pressurization pumps compared to traditional air pressurization. It also meets the high-quality adhesive coating requirements of new energy vehicle production for battery packs and high-voltage components. When changing containers or shutting down, close pressure reducing valve 41 and pressure regulating valve 42, insert the other end of the recovery hose on the small oil-free vacuum pump 6 into exhaust valve 5, and open the small oil-free vacuum pump 6 and exhaust valve 5 to extract nitrogen from glue container 2. The nitrogen is then filtered through metal sintered filter element 61 to remove any trace amounts of adhesive mist, and finally, the nitrogen is returned to nitrogen tank 4.The metal sintered filter element 61 is periodically removed for backflushing and regeneration cleaning to ensure long-term use and reduce operating costs. Furthermore, with nitrogen recovery, the internal pressure of the upper sealing cover 32, lower sealing cover 33, and trapezoidal rubber ring 35 returns to atmospheric pressure. The trapezoidal rubber ring 35 is no longer compressed and expanded by nitrogen pressure, thus restoring its close contact with the inner wall of the rubber container 2. This allows for a continuous and stable rise when the cover 3 is lifted by opening the cylinder 81. Compared to the traditional protruding design, this avoids significant wear and breakage. Moreover, compared to the traditional manual segmented lifting method, it greatly improves the lifting efficiency of the cover 3. Efficiency is improved by allowing the baffle 7 to slide downwards directly after the cover 3 rises and detaches from the glue tank 2. During this process, the glue adhering to the outer wall of the glue suction conduit 31 is scraped off. After removing the baffle 7, it can be cleaned, and replacing it with a new one improves glue replacement efficiency. A silicone retaining ring 72 fitted onto the lower end of the tube 71 provides support for the baffle 7 and also acts as a seal. The design of the baffle 7 effectively shields structures such as the lower sealing cover 33, reducing glue adhesion and thus shortening cleaning time. This further reduces the time required to replace the glue tank 2, thereby improving the glue application efficiency of the robotic arm's glue applicator on new energy vehicle battery packs and high-voltage components.
