Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile surface treatment, and in particular to an electrophoresis device and process for aluminum profile surface treatment. Background Art

[0002] In the field of aluminum profile surface treatment, electrophoresis technology is widely used due to its excellent coating quality and environmental protection characteristics. However, traditional electrophoresis equipment and processes face some technical problems that need to be solved when processing aluminum profiles.

[0003] First, regarding the automation and efficiency of electrophoresis equipment, traditional electrophoresis equipment often relies on manual operation when processing aluminum profiles, such as clamping, transferring, and removing aluminum profiles after electrophoresis. This manual operation method is not only inefficient, but also easily affected by human factors, resulting in unstable electrophoretic coating quality. With the development of modern manufacturing, higher requirements are placed on the surface treatment efficiency and quality of aluminum profiles. Therefore, how to realize the automation of electrophoresis equipment and improve production efficiency has become one of the technical problems that need to be solved urgently.

[0004] Secondly, the waste and pollution of electrophoretic fluid are also issues that cannot be ignored in traditional electrophoretic processes. During the electrophoretic process, the electrophoretic fluid will be continuously consumed and a certain amount of waste fluid will be generated. If these waste fluids are not effectively treated, it will not only waste resources but also pollute the environment. At the same time, since parameters such as the concentration and temperature of the electrophoretic fluid have an important influence on the quality of the coating, how to achieve the recycling and effective management of the electrophoretic fluid, reduce resource waste and environmental pollution, is also a technical problem that needs to be solved in the current electrophoretic process.

[0005] In response to the above technical problems, the industry has been exploring new electrophoresis equipment and process solutions. However, the existing electrophoresis equipment still has deficiencies in automation, production efficiency, and electrophoresis liquid management, and cannot meet the high efficiency, high quality, and environmental protection requirements of modern manufacturing for aluminum profile surface treatment. Therefore, it is necessary to improve and innovate the existing electrophoresis equipment and process to solve the above technical problems. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0034] Aluminum profiles are an indispensable material in modern architecture, and their surface quality directly affects the aesthetics and service life of the product.

However, traditional electrophoretic equipment has many shortcomings in the loading, transportation, processing and unloading of aluminum profiles, such as complex operation, low efficiency, and unstable coating quality. Therefore, the development of a new type of electrophoretic equipment and process for aluminum profile surface treatment is of great significance to improving the processing quality and production efficiency of aluminum profiles.

[0035] like Figures 1 to 5 As shown, the present invention provides an electrophoresis device for surface treatment of aluminum profiles, including a material containing frame 100, the material containing frame 100 includes a containing frame 110, a first limiting door 120 and a second limiting door 130 are respectively provided at both ends of the containing frame 110, and a first limiting portion 111 and a second limiting portion 121 are respectively provided on the first limiting door 120 and the second limiting door 130;

The container frame is used to support and fix the aluminum profile, and its structure can be customized according to the specifications and shapes of the aluminum profile. The first limiting door and the second limiting door are respectively provided with a first limiting portion and a second limiting portion, which are used to limit the position of the aluminum profile in the material container frame to prevent it from moving or deforming during the processing process.

[0039] Specifically, the grabbing device is used to grab the material container frame from the unprocessed placement area to the processing pool, and grab the processed material container frame from the processing pool to the processed placement area. The grabbing device includes a support seat, a track device, an upper support seat, a lower support seat and a support arm.

A clamping device is arranged on the support arm to clamp the material container frame.

[0040] The structure of the clamping device can be customized according to the shape and size of the container frame to ensure that the container frame can be stably clamped and prevented from falling off or being damaged during transportation. The clamping device can be driven pneumatically or electrically to improve the flexibility and efficiency of clamping.

[0041] Specifically, the processing device includes a processing pool and a tilting table. The processing pool contains electrophoretic liquid for electrophoretic coating of aluminum profiles. A tilting table is provided at one end of the processing pool, and the tilting table has an inclined surface inclined toward the processing pool. The design of the tilting table helps the material container frame to quickly discharge the liquid attached to the surface after the electrophoresis is completed, while avoiding the accumulation of liquid in the material container frame to cause pollution.

[0042] like Figure 1 and Figure 2 As shown, in this embodiment, an unprocessed placement area 500 and a processed placement area 600 are further included, and an air-drying device 700 corresponding to the processed placement area 600 is arranged in the processed placement area 600 .

[0043] In this embodiment, the unprocessed placement area and the processed placement area are used to place the material frame to be processed and the material frame after processing, respectively.

[0045] like Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, an opening and closing mechanism is provided between the first limiting door 120 and the accommodating frame 110, and an elastic mechanism is provided between the second limiting door 130 and the accommodating frame 110;

[0046] The opening and closing mechanism includes a hinge 122 and a locking member 123. The hinge 122 is disposed at one end of the first position-limiting door 120, the other end of the hinge 122 is disposed on the receiving frame 110, and the locking member 123 is disposed between the other end of the first position-limiting door 120 and the receiving frame 110;

A stopper 115 corresponding to the second position-limiting door 130 is provided on the accommodating frame 110 . The tension spring 133 is provided between the second position-limiting door 130 and the stopper 115 .

[0048] Specifically, an opening and closing mechanism is provided between the first limit door and the receiving frame to facilitate the opening and closing of the first limit door. The opening and closing mechanism includes a hinge and a locking member, wherein the hinge connects one end of the first limit door to the receiving frame, and the locking member is used to lock the first limit door on the receiving frame when the first limit door is closed. Similarly, an elastic mechanism is provided between the second limit door and the receiving frame to provide a certain elastic pressure when the second limit door is closed to enhance the limiting effect. The elastic mechanism includes a positioning member and a tension spring, wherein the positioning member is used to fix one end of the tension spring, and the other end of the tension spring is connected to the second limit door.

[0049] like Figure 1 As shown, in this embodiment, a support rod 112 corresponding to the clamping device 214 is provided at the upper end of the material containing frame 100 , and an embedded groove for accommodating at least a portion of the clamping device is opened in the support rod 112 .

[0050] Specifically, a support rod corresponding to the clamping device is arranged at the upper end of the material container frame, and the support rod is used to provide a support point for the clamping device when grabbing the material container frame. An embedded groove is opened in the support rod to accommodate the clamping component of the clamping device, thereby improving the stability and reliability of clamping.

[0051] like Figure 1 As shown, in this embodiment, a plurality of locking protrusions 322 are provided on the inclined surface 321 , and a positioning protrusion 114 is provided at the lower end of the material containing frame 100 .

[0052] Specifically, a plurality of positioning protrusions are arranged on the inclined surface to provide positioning points when the material containing frame is placed to prevent it from sliding or tilting. A positioning protrusion is arranged at the lower end of the material containing frame to cooperate with the positioning protrusion to achieve precise positioning.

[0053] like Figure 1 As shown, in this embodiment, an overflow hole 311 and a water flow channel connected to the tilting platform 320 are provided on the processing pool 310, and a water outlet hole 313 is provided at the lower end of the processing pool 310.

[0054] Specifically, a plurality of positioning protrusions are arranged on the inclined surface to provide positioning points when the material containing frame is placed to prevent it from sliding or tilting. A positioning protrusion is arranged at the lower end of the material containing frame to cooperate with the positioning protrusion to achieve precise positioning.

[0055] In this embodiment, an overflow hole and a water flow trough connected to the tilting platform are provided on the processing pool. The overflow hole is used to discharge excess liquid when there is too much electrophoretic liquid to prevent the liquid in the processing pool from overflowing and causing pollution. The water flow trough is used to guide the liquid flowing down the tilting surface back into the processing pool to achieve liquid recycling. A water outlet is provided at the lower end of the processing pool to discharge waste liquid in the processing pool or for cleaning.

[0056] The present invention also provides a process for electrophoresis equipment for surface treatment of aluminum profiles, which is characterized by comprising the following processing steps:

[0057] S1, loading the aluminum profile into the material containing frame 100, fixing the aluminum profile by the first limiting portion 111 and the second limiting portion 121, and placing the material containing frame 100 in the unprocessed placement area 500;

[0058] S2, the gripping device 200 clamps the material container frame 100, and puts the material container frame 100 into the processing pool 310, immerses it in the electrophoretic liquid and then performs electrophoretic coating;

[0059] S3, after the electrophoresis is completed, the material holding frame 100 is taken out of the processing pool 310 and placed on the inclined platform 320 for static storage, and the liquid attached to the material holding frame 100 falls on the inclined surface 321 and flows back to the processing pool 310 through the water flow trough;

[0060] S4, after the material containing frame 100 is left to stand for two minutes, the grabbing device 200 grabs the material containing frame 100 to the processed placement area 600 and blows it dry through the air drying device 700.

[0061] After air drying is completed, the locking member 123 in the opening and closing mechanism and the positioning member 132 in the elastic mechanism are opened to release the aluminum profile.

[0062] Specifically, when loading aluminum profiles, the aluminum profiles to be processed are loaded into the material container according to the specified quantity and arrangement. During the loading process, attention should be paid to whether the specifications and shapes of the aluminum profiles match the material container, and whether the aluminum profiles maintain an appropriate distance to avoid mutual collision or extrusion. At the same time, the position of the aluminum profile is fixed by the first limit part and the second limit part to ensure that it will not move or deform during the processing process.

[0063] When grabbing and transporting the material frame, start the grabbing device, adjust the clamping device to a suitable position and clamp the support rod of the material frame. Then, slide the support arm to the top of the unprocessed placement area through the track device, and grab the material frame from the unprocessed placement area. Then, the material frame is transported to the top of the processing pool through the swing of the track device and the support arm, and is ready to be placed in the processing pool.

[0064] During electrophoretic coating, the material container is slowly placed into the processing tank so that it is completely immersed in the electrophoretic solution. During the electrophoretic process, the thickness and quality of the coating are adjusted by controlling the composition, temperature, voltage and other parameters of the electrophoretic solution. The electrophoretic time can be adjusted according to the material of the aluminum profile and the coating requirements. After the electrophoresis is completed, the material container is removed from the processing tank and placed on a tilting table to rest.

[0065] When the attached liquid is discharged and allowed to stand, the liquid attached to the surface will flow down along the inclined surface and flow back into the processing pool through the water flow channel when the material frame is allowed to stand on the tilting table. At the same time, the cooperation of the positioning protrusion and the positioning protrusion can prevent the material frame from sliding or tilting during the standing process. The standing time can be adjusted according to the material and coating requirements of the aluminum profile, usually about 2 minutes. Standing helps to make the coating more evenly and firmly adhere to the surface of the aluminum profile.

[0066] When grabbing and transporting to the processed placement area, start the grabbing device, adjust the clamping device to a suitable position and clamp the support rod of the material frame. Then, slide the support arm to the top of the tilting table through the track device, and grab the material frame from the tilting table. Then, the material frame is transported to the top of the processed placement area through the swing of the track device and the support arm, and is ready to be placed in the processed placement area.

[0067] During air drying, place the material frame under the corresponding air drying device in the processed placement area. Start the air drying device to quickly dry the material frame. The air drying time can be adjusted according to the material and coating requirements of the aluminum profile. After air drying is completed, turn off the air drying device and wait for the next step.

[0068] When releasing the aluminum profile, after air drying, the locking member in the opening and closing mechanism and the positioning member in the opening elastic mechanism are opened to release the aluminum profile. At this time, the staff can conveniently take out the aluminum profile and carry out subsequent processing or packaging.

[0069] The present embodiment provides an electrophoresis device for surface treatment of aluminum profiles, including a material storage frame, a gripping device, a processing device, an unprocessed placement area and a processed placement area. The material storage frame includes a storage frame and a first limit door and a second limit door arranged at both ends of the storage frame. The first limit door and the second limit door are respectively provided with a first limit portion and a second limit portion. The gripping device includes a support seat, a track device, an upper support seat, a lower support seat and a support arm. A clamping device is provided on the support arm. The processing device includes a processing pool and a tilting table. The tilting table has an inclined surface tilted toward the processing pool. The unprocessed placement area and the processed placement area are respectively used to place the material storage frame to be processed and the material storage frame after processing. An air-drying device corresponding to the processed placement area is provided in the processed placement area.

[0070] When in use, the aluminum profile to be processed is loaded into the material container frame, and its position is fixed by the first limit part and the second limit part. Then the grabbing device is started to grab the material container frame from the unprocessed placement area and put it into the processing tank to immerse it in the electrophoretic liquid for electrophoretic coating treatment. After the electrophoresis is completed, the material container frame is taken out and placed on the tilting table to stand. After the standing is completed, the grabbing device is started again to grab the material container frame to the processed placement area and blow dry it through the air drying device. Finally, the aluminum profile is released for subsequent processing or packaging.

[0071] The present invention has many application scenarios, including but not limited to the following description scenarios:

[0072] Aluminum profile manufacturers can use this electrophoresis equipment to perform surface coating treatment on aluminum profiles to improve the aesthetics and corrosion resistance of the products and meet the market demand for high-quality aluminum profiles.
