Description

Technical Field

[0001] This utility model relates to the field of electrophoretic coating production technology, specifically a pre-cleaning device for electrophoretic coating production. Background Technology

Both the pre-degreasing tank and the primary degreasing tank contain a degreasing agent. Both the first and second spray tanks are equipped with silane spraying mechanisms. The bottom of the immersion tank contains a silane solution sufficient to completely immerse the parts. The bottom of the second spray tank is connected to the immersion tank via a pipe. The upper part of the immersion tank is equipped with a first overflow pipe connected to the first spray tank. This utility model has the technical effect of reusing silane, thereby reducing production costs.

[0003] In the prior art, including the aforementioned patents, automotive parts and other workpieces often have complex shapes and numerous dead corners, grooves, and bends. For some workpieces with stains on two or more sides, cleaning only one side cannot effectively remove all stains. For example, in the production of automotive parts, some stamped parts may have oil stains and processing debris on both sides. Without a flipping structure, it is difficult to completely remove these stains, thus affecting the appearance and protective performance after electrophoretic coating. Therefore, it is necessary to design a pre-cleaning device for electrophoretic coating production with a flipping structure. Utility Model Content

[0004] The purpose of this invention is to provide a pre-cleaning device for electrophoretic coating production, so as to solve the problem of insufficient single-sided cleaning mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-cleaning device for electrophoretic coating production, comprising a support frame, a roller conveyor belt mounted on the top of the support frame, a fixed frame fixedly connected to the top of the support frame, an adjusting cylinder mounted on the top of the fixed frame, a cleaning nozzle fixedly connected to the output end of the adjusting cylinder, a connecting pipe mounted on the outer wall of the adjusting cylinder, a feeding rack fixedly connected to one side of the support frame, a flipping assembly mounted on the top of the feeding rack, and a cleaning assembly mounted on the top of the support frame.

[0006] Furthermore, the roller conveyor belt is flush with the loading rack, and the conveying directions of the roller conveyor belt and the loading rack are the same.

[0007] Furthermore, the fixing frame is located on both sides of the roller conveyor belt, and the number of cleaning nozzles is the same as the number of fixing frames, with the cleaning nozzles located above the roller conveyor belt.

[0008] Furthermore, the flipping assembly includes a connecting shaft, a flipping cylinder, and a flipping panel. The connecting shaft is installed on the outer wall of the bracket, the flipping cylinder is installed on the outer wall of the bracket via the connecting shaft, and the flipping panel is connected to the outer wall of the bracket via a rotating shaft.

[0009] Furthermore, the output end of the flipping cylinder is connected to the flipping panel via a connecting shaft and a connecting rod, and the rotation angle of the flipping panel is 90°.

[0010] Furthermore, the cleaning assembly includes a lifting cylinder, a mounting bracket, an electric telescopic rod, a sliding bracket, an air pump, and an air gun. The lifting cylinder is mounted on one side of the bracket, and the output end of the lifting cylinder is fixedly connected to the mounting bracket. The electric telescopic rod is mounted on the top of the mounting bracket, and the output end of the electric telescopic rod is fixedly connected to the sliding bracket. The air pump is mounted on the top of the sliding bracket, and the air gun is mounted on the output end of the air pump.

[0011] Furthermore, the cleaning components are positioned on both sides of the roller conveyor belt, and the sliding frame is slidably connected to the mounting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the pre-cleaning device for electrophoretic coating production is reasonable and has the following advantages:

[0013] (1) The pre-cleaning device can pre-treat the parts to be coated by electrophoresis, reducing dust and stains. At the same time, a flipping component is set on one side of the roller conveyor belt. The flipping structure allows different sides of the workpiece to face the cleaning nozzle in turn, so that the cleaning agent can fully cover and rinse each part. Dust, oil and impurities in hidden places such as the inner wall of holes and corner gaps can be effectively removed, avoiding the residual impurities due to inadequate cleaning, which will affect the quality of subsequent electrophoretic coating. For stubborn stains that are firmly attached, after flipping, they can be rinsed from different directions and angles. With the chemical action of the cleaning agent, the stain removal effect can be enhanced and the cleaning cleanliness can be improved. At the same time, during the conveying process using the roller conveyor belt, there is no need to manually flip the workpiece. The equipment automatically completes the flipping action, reducing auxiliary time. It can also coordinate with the conveying process to achieve continuous automated cleaning and speed up the workpiece cleaning rhythm.

[0014] (2) By using the cleaning component, pneumatic cleaning of the flipped parts can be performed during the flipping process, resulting in more thorough pre-cleaning and a high degree of cleanliness on the workpiece surface. Air blowing is used, with air guns installed on both sides for blowing. The high-pressure airflow can quickly blow away larger particles of dust, welding slag, metal shavings and other impurities on the workpiece surface. During electrophoretic coating, the paint can better bond with the workpiece surface, enhance the adhesion of the paint film, and reduce coating defects caused by impurities, such as pinholes and peeling. Pre-cleaning with air guns can remove some impurities and reduce the impurity content in the cleaning agent. This reduces the situation where the cleaning agent fails prematurely and needs to be replaced frequently due to excessive impurities, saves the amount of cleaning agent used and costs, and reduces the amount of waste cleaning agent to be disposed of. The air gun blows away the loose impurities on the surface first, and the subsequent water washing, chemical cleaning and other processes can act more efficiently on the workpiece surface, shortening the overall cleaning time.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0023] Example 1:

[0024] A pre-cleaning device for electrophoretic coating production includes a support 1, a roller conveyor belt 2 mounted on the top of the support 1, a fixed frame 3 fixedly connected to the top of the support 1, an adjusting cylinder 4 mounted on the top of the fixed frame 3, a cleaning nozzle 5 fixedly connected to the output end of the adjusting cylinder 4, a connecting pipe 6 mounted on the outer wall of the adjusting cylinder 4, a feeding rack 7 fixedly connected to one side of the support 1, a flipping assembly 8 mounted on the top of the feeding rack 7, and a cleaning assembly 9 mounted on the top of the support 1.

[0025] The above structure can pre-treat the parts to be coated by electrophoresis through the pre-cleaning device, reducing dust and stain residue. At the same time, a flipping component 8 is set on one side of the roller conveyor belt 2. The flipping structure allows different sides of the workpiece to face the cleaning nozzle in turn, so that the cleaning agent can fully cover and rinse each part. Dust, oil and impurities in hidden places such as the inner walls of holes and corners can be effectively removed, avoiding the residual impurities due to inadequate cleaning, which will affect the quality of subsequent electrophoretic coating.

[0026] Furthermore, the roller conveyor belt 2 is flush with the loading rack 7, and the roller conveyor belt 2 and the loading rack 7 have the same conveying direction. The fixing frame 3 is set on both sides of the roller conveyor belt 2, and the number of cleaning nozzles 5 is the same as the number of fixing frames 3, and the cleaning nozzles 5 are located above the roller conveyor belt 2.

[0027] The above structure utilizes the roller conveyor belt 2 for conveying, eliminating the need for manual workpiece flipping. The equipment automatically completes the flipping action, reducing auxiliary time and enabling continuous automated cleaning in coordination with the conveying process, thus accelerating the workpiece cleaning pace.

[0028] Furthermore, the flipping assembly 8 includes a connecting shaft 801, a flipping cylinder 802, and a flipping panel 803. The connecting shaft 801 is installed on the outer wall of the bracket 1, and the flipping cylinder 802 is installed on the outer wall of the bracket 1 through the connecting shaft 801. The flipping panel 803 is connected to the outer wall of the bracket 1 through a rotating shaft. The output end of the flipping cylinder 802 is connected to the flipping panel 803 through the connecting shaft 801 and a connecting rod, and the rotation angle of the flipping panel 803 is 90°.

[0029] The above structure uses the extension and retraction of the flipping cylinder 802 to drive the connecting shaft 801 and the support rod to move, thereby driving the flipping panel 803 to rotate along the rotating shaft, thus performing the flipping operation.

[0030] Furthermore, the cleaning assembly 9 includes a lifting cylinder 901, a mounting bracket 902, an electric telescopic rod 903, a sliding frame 904, an air pump 905, and an air gun 906. The lifting cylinder 901 is mounted on one side of the bracket 1. The output end of the lifting cylinder 901 is fixedly connected to the mounting bracket 902. The electric telescopic rod 903 is mounted on the top of the mounting bracket 902. The output end of the electric telescopic rod 903 is fixedly connected to the sliding frame 904. The top of the sliding frame 904 is mounted on the air pump 905. The output end of the air pump 905 is mounted on the air gun 906. The cleaning assembly 9 is located on both sides of the roller conveyor belt 2. The sliding frame 904 is slidably connected to the mounting bracket 902.

[0031] The above structure utilizes the cleaning component 9 to perform pneumatic cleaning on the flipped parts during the flipping process, resulting in more thorough pre-cleaning and high surface cleanliness of the workpiece. It employs air blowing, using air guns 906 installed on both sides to blow away large particles of dust, welding slag, metal shavings, and other impurities from the workpiece surface.

[0032] Working principle: In use, firstly, the feeding rack 7 is used for feeding, and the feeding rack 7 is set between two sets of roller conveyor belts 2. At the same time, there are multiple sets of this pre-cleaning device, all set on the production line, to transport the parts on the roller conveyor belts 2.

[0033] Secondly, a flipping assembly 8 is provided on one side of the roller conveyor belt 2. The flipping structure allows different sides of the workpiece to face the cleaning nozzle in sequence, so that the cleaning agent can fully cover and rinse each part. Dust, oil and impurities in hidden places such as the inner walls of holes and corners can be effectively removed, avoiding residual impurities due to inadequate cleaning, which would affect the quality of subsequent electrophoretic coating. For stubborn stains that are firmly attached, after flipping, they can be rinsed from different directions and angles. Combined with the chemical action of the cleaning agent, the stain removal effect can be enhanced and the cleaning cleanliness can be improved. At the same time, during the conveying process of the roller conveyor belt 2, the extension and retraction of the flipping cylinder 802 drives the connecting shaft 801 and the support rod to move, thereby driving the flipping panel 803 to rotate along the rotating shaft, thus performing the flipping operation. There is no need for manual flipping of the workpiece. The equipment automatically completes the flipping action, reducing auxiliary time. It can also be coordinated with the conveying process to achieve continuous automated cleaning and speed up the workpiece cleaning rhythm.

[0034] Finally, the cleaning component 9 can be used to pneumatically clean the flipped parts during the flipping process, making the pre-cleaning more thorough and the surface cleanliness of the workpiece high. It uses air blowing and air guns 906 installed on both sides to blow away the larger particles of dust, welding slag, metal shavings and other impurities on the surface of the workpiece. The cleaning component 9 itself can be adjusted according to the size of the parts. It can be raised and lowered using the lifting cylinder 901. At the same time, the distance of the air gun 906 can be adjusted by activating the electric telescopic rod 903.
