Description

Technical Field

[0001] This utility model relates to the field of automotive parts production equipment technology, and in particular to an automotive dashboard crossbeam oil injection device. Background Technology

[0002] In recent years, the automotive industry has faced the dual pressures of cost reduction and efficiency improvement, as well as environmental upgrades, leading OEMs to optimize component manufacturing processes. For example, some OEMs, while ensuring performance standards are met, have optimized the surface treatment of dashboard crossbeams from electrophoresis to rust-preventive oil spraying, using a process that prioritizes cost reduction through technology. This transformation reflects the automotive industry's shift from solely controlling manufacturing costs to prioritizing technological cost reduction.

[0003] Application No. 2015106899400 discloses a cylinder liner oiling machine, which conveys the workpiece through a conveying system, applies oil through an oiling system, and sprays the conveyed cylinder liner through an atomizing nozzle, thereby effectively ensuring the oiling effect on the cylinder liner.

[0004] However, to ensure the coating effect, sufficient oil mist needs to be sprayed. However, the sprayed oil mist gathers on the workpiece surface to form oil droplets, which affects the coating quality. Furthermore, during the spraying process, the oil mist gradually adheres to the inner wall of the spraying chamber. Long-term processing and production use makes cleaning inconvenient and wastes the use of rust-preventive oil, increasing production costs. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose an oil spraying device for automotive dashboard crossbeams to solve the problem of oil droplets and oil mist adhering to the workpiece surface and causing waste due to their adhesion to the inner wall of the processing chamber.

[0006] Based on the above objectives, this utility model provides an automotive dashboard crossbeam oil spraying device, including a conveyor belt, a processing chamber on the conveyor belt, a curtain inside the processing chamber, and an oil coating chamber and an oil blowing chamber separated by the curtain; an oil coating mechanism for coating workpieces is provided in the oil coating chamber; an oil blowing mechanism for blowing oil droplets off the surface of workpieces is provided in the oil blowing chamber; an oil mist treatment mechanism for recovering and treating oil mist inside the processing chamber is provided on the top of the processing chamber corresponding to both the oil coating chamber and the oil blowing chamber; an oil scraping mechanism for removing oil stains from the inner wall of the processing chamber is provided on the inside of the processing chamber; an oil storage tank is installed on one side of the conveyor belt, and the coating mechanism and the oil mist treatment mechanism are respectively connected to the oil storage tank.

[0007] A further improvement is that the oiling mechanism includes an oil pump and a nozzle. The nozzle is installed on the inner wall of the oiling chamber and is connected to the oil pump through a spray pipe. The oil pump is installed on an oil storage tank and is connected to the inside of the oil storage tank through an oil pipe.

[0008] A further improvement is that an unloading valve is installed on the nozzle.

[0009] A further improvement is that the oil blowing mechanism includes air knives, which are respectively installed on the top, bottom and side walls of the oil blowing chamber. A high-pressure air pump is installed on one side of the conveyor belt, and the high-pressure air pump is connected to the air knives through an air blowing pipeline.

[0010] A further improvement is that the oil mist treatment mechanism includes an oil mist fan and an oil mist treatment machine installed on the top of the processing chamber. The input end of the oil mist fan extends into the processing chamber, and the output end of the oil mist fan is connected to the oil mist treatment machine. The oil mist treatment machine is connected to the oil storage tank through an oil pipe.

[0011] A further improvement is that the oil scraping mechanism includes an elastic rubber scraper and an oil collection box. The oil collection box is detachably installed at the bottom of the side wall of the processing chamber. The elastic rubber scraper is set on the upper side of the oil collection box. Multiple elastic rubber scrapers are provided. The elastic rubber scrapers are rotatably installed on the inner wall of the processing chamber via a rotating shaft. One end of the rotating shaft passes through the inner wall of the processing chamber and is fixedly connected to a gear. A toothed block is connected to the side of the conveyor belt, and the toothed block meshes with the gear.

[0012] A further improvement is that an oil guide plate is installed on the side wall of the processing chamber. The oil guide plate is set on both sides of the elastic rubber scraper, and the end of the oil guide plate is inclined towards the oil collection box.

[0013] The beneficial effects of this utility model are as follows: By setting up an oiling mechanism, the nozzle sprays oil mist, which allows the rust-preventive oil to be evenly adhered to the surface of the workpiece, improving the uniformity and consistency of the coating; by setting up an oil blowing mechanism, the air knife blows air from the top, bottom and sides onto the workpiece conveyed in the middle, blowing off large oil droplets on the surface of the workpiece, so that an oil film can be quickly formed on the surface of the workpiece, which is convenient for subsequent packaging, improving processing efficiency and processing effect, and improving product quality.

[0014] By setting up an oil mist treatment mechanism, an oil mist fan sucks out the oil mist scattered in the processing chamber, and the oil mist treatment machine filters the sucked-out oil mist before returning it to the oil storage tank for reuse. The elastic rubber scraper rotates with the conveyor belt through the action of gears and toothed blocks. The elastic rubber scraper adheres to the inner wall of the processing chamber and scrapes off the oil mist attached to it. The oil guide plate scrapes off the oil mist scraped off by the elastic rubber scraper again. The scraped oil mist slides down the oil guide plate into the oil collection box for recycling and reuse, which effectively improves the utilization rate of resources, reduces production costs, and improves the cleanliness of the production environment.

[0024] like Figure 1 , 2As shown, an automotive dashboard crossbeam oil spraying device includes a conveyor belt 1, which is made of stainless steel mesh belt and is powered by a cycloidal pinwheel reducer and a motor to drive the conveyor belt 1. A processing chamber 2 is provided on the conveyor belt 1 and is mounted on the frame of the conveyor belt 1. A curtain 3 is provided inside the processing chamber 2 and is made of polyurethane. The processing chamber 2 is divided into an oiling chamber 4 and an oil blowing chamber 5 by the curtain 3.

[0025] The oiling chamber 4 is equipped with an oiling mechanism for applying oil to the workpiece. The oiling mechanism includes an oil pump 7 and a nozzle 8. The nozzle 8 is installed on the inner wall of the oiling chamber 4 and has a fan-shaped structure. The nozzle 8 is connected to the oil pump 7 through a spray pipe. The oil pump 7 is installed on the oil storage tank 6 and is connected to the oil storage tank 6 through an oil pipe. The oil pump 7 is a Southern centrifugal pump. A precision filter with a filtration accuracy of 5μm is also installed between the oil pump 7 and the oil storage tank 6. The oil pump 7 draws rust-preventive oil from the oil storage tank 6 through the oil pipe. The rust-preventive oil is filtered through the precision filter to reduce impurities in the rust-preventive oil.

[0026] An unloading valve is installed on the nozzle, which is used to adjust the flow rate and pressure during atomization.

[0027] The oil blowing chamber 5 is equipped with an oil blowing mechanism for blowing off oil droplets from the surface of the workpiece. The oil blowing mechanism includes air knives 9, which are respectively installed on the top, bottom, and side walls of the oil blowing chamber 5. A high-pressure air pump 10 is installed on one side of the conveyor belt 1. The high-pressure air pump 10 is connected to the air knife 9 through an air blowing pipe. A solenoid valve is installed on the air blowing pipe. The high-pressure air pump 10 delivers airflow to the air knife 9 through the air blowing pipe. The air knife 9 blows oil onto the workpiece conveyed from the top, bottom, and sides towards the middle, preventing large oil droplets from adhering to the surface of the workpiece and preventing oil droplets from flowing down after unloading, which would affect the working environment. The workpiece is blown oil by the oil blowing mechanism, leaving only a single layer of oil film on the surface of the workpiece, allowing for direct packaging and improving production efficiency.

[0028] The top of the processing chamber 2 is equipped with an oil mist treatment mechanism corresponding to the oiling chamber 4 and the blowing chamber 5 to recover and treat the oil mist in the processing chamber 2, preventing excessive oil mist from spreading into the workshop. The oil mist treatment mechanism includes an oil mist fan 11 and an oil mist treatment machine 12 installed on the top of the processing chamber 2. The input end of the oil mist fan 11 extends into the processing chamber 2, and the output end of the oil mist fan 11 is connected to the oil mist treatment machine 12. The oil mist treatment machine 12 is connected to the oil storage tank 6 through an oil pipe. The oil mist fan 11 sucks out the oil mist sprayed from the oiling chamber 4 and the oil droplets blown up from the blowing chamber 5 and transports them into the oil mist treatment machine 12 for filtration, so that the oil mist can be collected into oil droplets and flow back into the oil storage tank 6 for recycling.

[0029] like Figure 3 , 4As shown, a scraping mechanism for removing oil stains from the inner wall of the processing chamber 2 is installed inside the processing chamber 2. The scraping mechanism includes an elastic rubber scraper 13 and an oil collection box 14. The oil collection box 14 is detachably installed at the bottom of the side wall of the processing chamber 2. The elastic rubber scraper 13 is located on the upper side of the oil collection box 14. Multiple elastic rubber scrapers 13 are provided. The elastic rubber scrapers 13 are rotatably installed on the inner wall of the processing chamber 2 via a rotating shaft 15. One end of the rotating shaft 15 passes through the inner wall of the processing chamber 2 and is fixedly connected to a gear 16. A toothed block 17 is connected to the side of the conveyor belt 1. The toothed block 17 meshes with the gear 16. The conveyor belt 1 drives the toothed block 17 to move. During the movement of the toothed block 17, it meshes with the gear 16 and drives the gear 16. 6. When the gear 16 rotates, it drives the elastic rubber scraper 13 to rotate via the rotating shaft 15. The elastic rubber scraper 13 adheres to the inner wall of the processing chamber 2 and scrapes off the oil mist adhering to the inner wall of the processing chamber 2. An oil guide plate 18 is installed on the side wall of the processing chamber 2. The oil guide plate 18 is set on both sides of the elastic rubber scraper 13. The end of the oil guide plate 18 is inclined towards the oil collection box 14. During the rotation of the elastic rubber scraper 13, it contacts the oil guide plate 18 and is squeezed and bent. With further rotation, the oil guide plate 18 scrapes off the oil droplets on the elastic rubber scraper 13. The scraped oil droplets slide down through the inclined surface of the oil guide plate 18 and finally drip into the oil collection box 14 for recycling, thereby improving the utilization rate of the rust-preventive oil.

[0030] An oil storage tank 6 is installed on one side of the conveyor belt 1. The coating mechanism and the oil mist treatment mechanism are connected to the oil storage tank 6 respectively. The oil storage tank 6 is provided with an oil drain port, an oil return port, a sewage outlet, and an oil filling port. The coating mechanism is connected to the oil storage tank 6 through the oil drain port, and the oil mist treatment mechanism is connected to the oil storage tank 6 through the oil return port. A drawer-type filter screen is installed in the oil return port. The filter screen is an 80-mesh stainless steel filter screen. A liquid level gauge is installed on one side of the oil storage tank 6 to observe the liquid level in the oil storage tank 6.

[0031] During processing, the workpiece is conveyed by conveyor belt 1. After entering the oiling chamber 4, the rust-preventive oil is pressurized by oil pump 7 and sprayed into the oiling chamber 4 through nozzle 8 as an oil mist. The oil mist adheres to the surface of the workpiece as it passes through. After spraying, the workpiece enters the blowing chamber 5, where air knife 9 blows oil off the workpiece from the top, bottom, and sides, removing large oil droplets from the surface. After blowing, the workpiece is conveyed away from the processing chamber 2 by conveyor belt 1 for subsequent packaging. During the spraying and blowing process, the oil mist treatment mechanism absorbs and treats the scattered oil mist, improving the utilization rate of the rust-preventive oil. The elastic rubber scraper 13 rotates with the conveyor belt 1, scraping off the oil mist adhering to the inner wall of the processing chamber 2. The oil guide plate 18 scrapes off the oil droplets on the elastic rubber scraper 13, and the scraped oil droplets slide down the oil guide plate 18 into the oil collection box 14 for recycling, allowing the rust-preventive oil to be reused and improving resource utilization.
