Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile processing, in particular to non-immersion pre-treatment equipment for coating of aluminum battery boxes. Background Art
[0002] In recent years, new energy vehicles have developed rapidly. The battery trays or battery boxes that hold the battery packs are mostly made of aluminum alloy. After the aluminum alloy battery box is machined, it needs to be sprayed or oxidized to obtain a denser, more wear-resistant, or more corrosion-resistant coating surface and oxidized surface. Before entering the surface treatment process, the processing emulsion, cutting oil, etc. on the surface of the battery box must be removed to avoid adverse effects on subsequent surface treatment.
[0003] Usually, the pre-treatment cleaning of the battery box is mainly done manually. The battery box is lifted and moved by an overhead crane or a lifting device, and then enters the cleaning liquid tank, clean water tank, pickling liquid tank, etc. for immersion cleaning. After immersion cleaning in multiple cleaning tanks, most of the stains on the battery box can be removed. However, this method requires the use of lifting equipment or lifting equipment, and multiple cleaning tanks occupy a large area, occupying more production areas. Moreover, although the battery box has been immersed in multiple cleaning tanks for immersion cleaning, due to the presence of multiple small-sized corners and cleaning dead zones in the battery box, the immersion cleaning method still cannot achieve a thorough cleaning effect. Summary of the invention
[0004] In order to achieve the above purpose, the utility model utilizes a roller conveyor line + a robot laser cleaning device + a robot atomizing cleaning device + an online drying furnace to form a special aluminum battery box cleaning equipment, which has the advantages of good cleaning effect, high efficiency and compact structure.
[0005] The technical solution of the utility model is as follows:
[0006] A non-immersion pre-treatment equipment for coating an aluminum battery case, the equipment uses a conveyor roller as a water conveying channel, a robot laser cleaning device is arranged on the front end side of the conveyor roller, and a plurality of robot atomizing cleaning devices are arranged on the downstream side of the robot laser cleaning device, the end of the conveyor roller is connected to a translation chain plate, and a drying furnace is installed on the translation chain plate.
[0007] The robot laser cleaning device adopts KUKA robot KR60-3 and Haiyi laser cleaning system. Two laser cleaning guns are installed at the end of the robot flange to increase the working scanning range and improve the production rhythm. The scanning range of the laser cleaning system is 20-400MM, and the laser power can be adjusted up to 2000W. The high-energy laser beam irradiates the surface of the workpiece, causing the dirt, rust or coating on the surface to evaporate or peel off instantly, and removes the surface attachments or surface coatings of the cleaning object at high speed and effectively, thereby achieving the effect of cleaning the workpiece.
[0008] The robot atomization cleaning device uses FANUC robot M-20ID / 12L, automatic atomization spray gun, and pneumatic diaphragm pump; clean water is sent to the spray gun by the pneumatic diaphragm pump, and the atomized water impacts the surface of the battery box to remove dirt.
[0009] A guardrail is arranged around the robot laser cleaning device. Since the laser cleaning device emits strong light during the working stage, a guardrail is arranged at the visual height of a person to protect the operator and prevent idle people from entering the laser cleaning area.
[0010] A blocking cylinder is arranged at the position corresponding to the robot laser cleaning device and the robot atomizing cleaning device on the conveying roller. When the battery box moves to the cleaning station, it is blocked by the raised block to prevent the battery box from passing the position and positioning, which is conducive to the robot arm of the cleaning device to perform accurate cleaning according to the procedure.
[0011] The end of the transmission roller is connected to the translation chain plate through the turning table A, the transfer roller and the turning table B. The turning table is an array of multiple bull's eye pulleys, which supports the bottom surface of the battery box. The battery box can be easily turned and moved manually to realize the turning of the assembly line and adapt to the layout of the workshop production area.
[0012] The front and rear ends of the drying furnace are the inlet and outlet respectively, and an air inlet fan is installed on the upper middle part, which is connected to the air inlet of the inner cavity, and a number of heaters are arranged below the air inlet. Cold air is injected from the fan on the top side of the drying furnace. After the cold air enters the inner cavity of the furnace, it is heated by the heating tube and becomes hot air that blows downward to dry the battery box moving along the chain plate below. The drying temperature is 140-170℃ and the drying time is 10min.
[0013] Advantages of utility models:
[0014] The aluminum battery box of the utility model is cleaned by laser + atomized water, which changes the status quo of traditional immersion cleaning, improves the cleaning degree of the dead zone of the battery box corner, and utilizes the close-range and all-round cleaning effect of the manipulator + laser and atomized water to achieve a thorough cleaning effect.
[0015] The utility model has high battery box assembly line transfer efficiency and avoids occupying workshop overhead cranes and lifting equipment.
[0016] The cleaning efficiency of the utility model is higher than that of the traditional immersion cleaning efficiency, and the time required for cleaning and drying a battery box is reduced by 40% on average. BRIEF DESCRIPTION OF THE DRAWINGS
