Description

Technical Field

[0001] This utility model belongs to the field of paint spraying technology for automotive parts, and relates to a pre-treatment structure for paint spraying of automotive parts. Background Technology

[0002] In the automotive manufacturing industry, the surface treatment quality of parts is crucial to the appearance and durability of the final product. This is especially true for plastic automotive parts; effective pretreatment before painting is a key step in ensuring the adhesion and aesthetics of the subsequent coating. Traditional pretreatment methods typically involve placing plastic automotive parts on automated conveyor systems that individually transport them to a workstation before the paint booth. However, before entering the painting process, to remove any grease, dust, and other contaminants from the surface of the parts, manual wiping with towels or other cloths is often necessary to achieve the desired degreasing and cleaning effect.

[0003] While this method can meet basic cleaning requirements to some extent, its drawbacks are also quite obvious. First, manual wiping not only consumes a lot of human resources, leading to a significant increase in labor costs, but this labor-intensive operation is also inefficient, greatly limiting the overall capacity and production speed of the production line. Utility Model Content

[0004] The purpose of this invention is to provide a pre-painting treatment structure for automotive parts, which replaces manual labor with an automated method of cleaning and removing contaminants from parts, thereby effectively improving production efficiency and reducing labor costs.

[0005] To solve the above-mentioned technical problems, this utility model provides a pre-treatment structure for painting automotive parts, including a long strip shell with openings at both the front and rear ends. An upper cleaning conveyor belt is provided in the upper part of the long strip shell. A first drive shaft is rotatably connected to both ends of the upper cleaning conveyor belt inside the long strip shell. A first drive motor for driving the first drive shaft to rotate is installed outside the long strip shell. An upper cleaning brush is provided on the outer side of the upper cleaning conveyor belt.

[0006] The lower front section of the long shell is provided with multiple parallel feeding conveyor belts, and the lower rear section of the long shell is provided with multiple parallel discharging conveyor belts. The feeding conveyor belts and the discharging conveyor belts are staggered in pairs. Multiple second drive shafts for driving all feeding conveyor belts and all discharging conveyor belts to move synchronously are rotatably connected inside the long shell. A second drive motor for driving the second drive shafts to rotate is installed outside the long shell.

[0007] Multiple front lower cleaning conveyor belts are arranged at the feeding conveyor belt, and multiple rear lower cleaning conveyor belts are arranged at the discharging conveyor belt, with each rear lower cleaning conveyor belt having a third drive shaft rotatably connected to both ends of all the front lower cleaning conveyor belts and both ends of all the rear lower cleaning conveyor belts inside the long shell. A third drive motor for driving the rotation of the third drive shafts is installed outside the long shell. Lower cleaning brushes are provided on the outer side of each front lower cleaning conveyor belt and the outer side of each rear lower cleaning conveyor belt.

[0008] By adopting the above technical solution, the first drive motor drives the upper cleaning conveyor belt to move backward, the second drive motor drives the feeding conveyor belt and the discharge conveyor belt to move backward, and their movement speed is faster than that of the upper cleaning conveyor belt. The third drive motor drives the front lower cleaning conveyor belt and the rear lower cleaning conveyor belt to move forward. When cleaning and removing oil stains from parts, the parts are placed on the feeding conveyor belt, and the parts move backward with the feeding conveyor belt. The upper cleaning brush on the upper cleaning conveyor belt cleans the upper surface of the parts backward, and the lower cleaning brush on the front lower cleaning conveyor belt moves forward to clean the lower surface of the parts backward. When the parts are transferred from the feeding conveyor belt to the discharge conveyor belt, the upper cleaning conveyor belt can also provide a backward thrust for the parts. On the discharge conveyor belt, the lower cleaning brush on the rear lower cleaning conveyor belt moves forward to clean the lower surface of the parts backward, which is used to supplement the cleaning of the parts that the lower cleaning brush on the front lower cleaning conveyor belt did not clean. Then, the parts are discharged from the end of the discharge conveyor belt, completing the cleaning process.

[0009] The present invention is further configured such that three second drive shafts are rotatably connected inside the elongated housing, wherein two of the second drive shafts are located inside the outer end of all the feeding conveyor belts and all the discharging conveyor belts, and one is located in the middle and inside the inner end of all the feeding conveyor belts and all the discharging conveyor belts. The power output shaft of the second drive motor is connected to the second drive shaft in the middle.

[0010] The present invention is further configured such that an upper scraper groove is horizontally arranged inside the elongated housing above the upper cleaning conveyor belt, and an upper scraper strip is arranged on the lower side of the upper scraper groove downward and away from the feeding conveyor belt, which contacts the upper cleaning brush. An upper drip pipe is horizontally arranged inside the elongated housing on the side of the upper scraper groove close to the feeding conveyor belt, and a plurality of upper drip holes are opened on the lower side of the upper drip pipe along its length direction.

[0011] The present invention is further configured such that, within the elongated housing, a lower squeegee with an upper opening is horizontally arranged below both the front and rear lower cleaning conveyors; each lower squeegee has multiple lower scraper strips corresponding one-to-one with either the front or rear lower cleaning conveyor; the inclination direction of each lower scraper strip is opposite to that of the upper scraper strip; a lower drip pipe is horizontally arranged within the elongated housing below both the front and rear lower cleaning conveyors; and multiple lower water outlet holes corresponding one-to-one with the lower cleaning brush are opened on the upper side without the lower drip pipe.

[0012] The present invention is further configured such that one end of the upper scraper groove is connected to an upper sewage pipe extending out of the elongated shell, and one end of the upper drip pipe is connected to an upper water inlet pipe extending out of the elongated shell.

[0013] The present invention is further configured such that one end of each lower scraper groove is connected to a lower sewage pipe extending out of the elongated shell, and one end of each lower drip pipe is connected to a lower water inlet pipe extending out of the elongated shell.

[0014] The present invention is further configured such that a sewage tank is provided outside the elongated shell, and the free ends of the upper sewage pipe and each lower sewage pipe extend into the sewage tank.

[0015] The present invention is further configured such that a transition thin plate is connected to the elongated shell at the junction of the feeding conveyor belt and the lower cleaning brush, the junction of the feeding conveyor belt and the discharge conveyor belt, and the junction of the discharge conveyor belt and the lower cleaning brush.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Firstly, by using the feeding conveyor belt and the discharging conveyor belt to transport the parts to one side, the upper cleaning brush on the surface of the upper cleaning conveyor belt cleans the upper surface of the parts, and the lower cleaning brushes on the front lower cleaning conveyor belt and the rear lower cleaning conveyor belt alternately clean the lower surface of the parts. By using an automated cleaning and decontamination method to replace manual labor, production efficiency can be effectively improved and labor costs can be reduced.

[0018] Secondly, when using the upper and lower cleaning brushes to clean and remove oil stains from the surface of parts, they can continuously scrape away dirty water and continuously replenish clean water, so that the upper and lower cleaning brushes can always be kept clean and the cleaning effect is better.
