[0013] About Silanes for Electrophoresis Processing:

[0014] Silane plays a key role in electrophoretic processing. As a metal surface pretreatment technology, it is environmentally friendly, energy-saving and highly efficient. Silane treatment technology is widely used in the pretreatment of metal surfaces to enhance the adhesion and corrosion resistance of coatings. Silane first generates silanols through a hydrolysis reaction. The silanol hydroxyl groups form hydrogen bonds with inorganic substances on the metal surface, and further form covalent bonds through a dehydration reaction, thereby forming a film on the metal surface.

[0015] When the product undergoes electrophoresis processing, it needs to be immersed in a liquid silane tank for oil treatment to form a dense silane film on the surface of the decorative strip, so that subsequent electrophoretic coating and other processes can proceed smoothly. During the oil immersion treatment, debris adhering to the surface of the product enters the silane tank. After long-term operation, the silane tank contains a large amount of impurities, which in turn affects the silane treatment effect of the subsequent product, thereby reducing the production quality of the product;

[0016] The existing technologies all adopt the technical means of treating the silane tank to remove impurities, which is too inefficient. In view of this, the inventors propose a silane treatment device for electrophoresis processing. Utility Model Content

[0017] The purpose of the utility model is to solve the problem of low efficiency when a traditional silane tank processes internal impurities.

[0018] In order to achieve the above objectives, the present invention provides the following basic solutions:

[0019] The silane treatment device for electrophoresis processing includes a silane treatment tank, a plurality of limit blocks arranged inside the silane treatment tank close to the tank wall, and a filter component with a size equal to the inner diameter of the silane treatment tank, wherein the filter component is slidably connected to the limit blocks.

[0020] The principles and effects of this basic solution are:

[0021] 1. Compared with the existing technology, the present device has a simple structure and an ingenious design. The core of the present device is the filtering component. The traditional technology is to use salvage to remove non-liquid silane impurities located in the silane tank, which is too slow. Therefore, the present device is provided with a filtering component. The advantage is that no matter the density is greater than liquid silane, or the density is equivalent to liquid silane, or the density is less than liquid silane, under the action of the filtering component, the impurities are all located at the bottom of the silane tank, thereby realizing the separation of impurities and liquid silane. In terms of speed, since there is no need to salvage the non-liquid silane impurities located in the silane tank, it is only necessary to sink the non-liquid silane impurities to the bottom and reuse the liquid silane. From this point of view, the present device can reuse the liquid ghost doll faster and thus more efficiently, solving the problem of low efficiency of traditional silane tanks in handling internal impurities.

[0022] 2. Compared with the prior art, this device is provided with a limit block, and the filter assembly is slidably connected to the limit block. The limit block accelerates the falling of the filter assembly and realizes the correct falling of the filter assembly.

[0023] Furthermore, the filter assembly includes a frame, a main body arranged in the frame and composed of a plurality of connecting rods, a mounting hole opened in the main body, and filter paper arranged in the mounting hole. The filter assembly is used to separate the liquid silane from the impurities.

[0024] Furthermore, the main body is provided with connection grooves whose number and positions correspond to the limit blocks, and the connection grooves are slidably connected to the limit blocks to achieve the correct drop of the filter assembly.

[0025] Furthermore, a plurality of grab bars are provided at the end of the frame away from the limit block. The filter assembly is manually lowered.

[0026] Furthermore, the filter assembly further includes a self-drop assembly comprising a connecting frame and a latch rod slidably connected to the connecting frame. The connecting frame is disposed on an end surface of the silane treatment tank. One end of the latch rod extends through the connecting frame and is disposed perpendicularly thereto. The other end of the latch rod is provided with an anti-sliding block. The latch rod extending through the connecting frame forms a restricted area that supports the weight of the frame, thereby enabling the filter assembly to self-drop.

[0027] Furthermore, the filter assembly includes a deceleration assembly comprising a positioning rod disposed outside the stop block and positioning holes formed in the main body, the positions and number of which correspond to the positioning rods. The outer periphery of the positioning rods is wrapped with friction pads, which contact the inner walls of the positioning holes. Since water takes time to pass through the filter paper, the deceleration assembly is provided to provide a certain amount of time for the water to pass through, thereby slowing the descent of the filter assembly.

[0028] Furthermore, the friction skin is a resin-based friction skin comprising reinforcing fibers, friction powder and resin, and the resin-based friction skin with a high friction coefficient is used as a very fine structure of the retarding component.

[0029] Furthermore, a plurality of support columns are provided at the bottom of the silane treatment tank, and the free ends of the support columns are provided with rubber anti-skid pads, thereby improving the installation stability of the device.

[0030] Furthermore, when the main body is slidably connected to the stopper, the main body enters the silane treatment tank and contacts the bottom of the silane treatment tank. If the internal space of the silane treatment tank is set to maximize the outflow, it is convenient to use multiple filter assemblies without frequent replacement of filter assemblies.

[0036] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0037] The figure marks in the drawings of the specification include: silane treatment tank 1, support column 2, anti-slip pad 3, limit block 4, positioning rod 5, connecting frame 6, pin 7, filter assembly 8, frame 801, connecting rod 802, connecting groove 9, mounting hole 10, positioning hole 11, friction skin 12, filter paper 13, grab bar 14.

[0038] Implementation example Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown:

[0039] Example 1: A silane treatment device for electrophoresis processing includes a silane treatment tank 1, a plurality of limit blocks 4 arranged inside the silane treatment tank 1 close to the tank wall of the silane treatment tank 1, and a filter assembly 8 with a size equal to the inner diameter of the silane treatment tank 1, and the filter assembly 8 is slidably connected to the limit blocks 4.

[0040] The filter assembly 8 comprises a frame 801, a main body mounted within the frame 801 and composed of several connecting rods 802, a mounting hole 10 formed in the main body, and filter paper 13 positioned within the mounting hole 10. The filter assembly 8 separates liquid silane from impurities. The main body is provided with connecting grooves 9, each corresponding in number and position to the stop blocks 4. These connecting grooves 9 are slidably connected to the stop blocks 4. To ensure the proper lowering of the filter assembly 8, several grab bars 14 are provided at the end of the frame 801 away from the stop blocks 4. This allows for manual lowering of the filter assembly 8.

[0041] Specifically: the filter paper 13 is used to block solid impurities and allow liquid to pass through. The bottom of the silane treatment tank 1 is provided with a plurality of support columns 2, and the free ends of the support columns 2 are provided with rubber anti-slip pads 3 to improve the installation stability of the device.

[0042] When the main body is slidably connected to the stopper 4, the main body enters the silane treatment tank 1 and contacts the bottom of the silane treatment tank 1. If the internal space of the silane treatment tank 1 is set to maximize the outflow, it is convenient to use multiple filter assemblies 8 without having to frequently replace the filter assemblies 8.

[0043] Specifically, after the solid impurities are filtered using the filter assembly 8, all the solid impurities are blocked at the bottom of the silane treatment tank 1, while the liquid silane passes through the filter paper 13 and is located on the other side of the main body, and the filter assembly 8 is used to separate the impurities and the liquid;

[0044] Then the liquid silane can be used again. After the liquid silane is used again, impurities continue to be generated. The filter component 8 is used again to separate the impurities and the liquid. This improves the filtration efficiency because there is no need to remove the impurities.

[0045] The second embodiment differs from the first embodiment only in that the filter assembly 8 is lowered by a manual grabbing rod 14 , and the filter assembly 8 is lowered manually, and the falling speed of the filter assembly 8 is controlled by the manual grabbing force.

[0046] The filter assembly 8 further comprises a self-drop assembly comprising a connecting frame 6 and a latch rod 7 slidably connected to the connecting frame 6. The connecting frame 6 is disposed on the end surface of the silane treatment tank 1. One end of the latch rod 7 extends through the connecting frame 6 and is disposed perpendicularly thereto. The other end of the latch rod 7 is provided with an anti-sliding block. The latch rod 7 extending through the connecting frame 6 forms a restricted area that supports the weight of the frame 801, thereby enabling the filter assembly 8 to self-drop.

[0047] The filter assembly 8 further includes a deceleration assembly comprising a positioning rod 5 disposed outside the stop block 4 and positioning holes 11 formed on the main body, the positions and number of which correspond to the positioning rods 5. The outer periphery of the positioning rods 5 is wrapped with friction skin 12, which contacts the inner wall of the positioning holes 11. Since water takes time to pass through the filter paper 13, a deceleration assembly is provided to provide a certain amount of time for the water to pass through, thereby slowing down the descent speed of the filter assembly 8.

[0048] The second embodiment is characterized by the use of self-falling. The advantage of self-falling is that it frees up hands, but the disadvantage is that the falling speed may be too fast, resulting in insufficient filtering time. Therefore, a retarding component is provided. The friction skin 12 is a resin-based friction skin 12, which includes reinforcing fibers, friction powder, and resin. The resin-based friction skin 12 with a high friction coefficient is used as a very fine structure of the retarding component.

[0049] A high friction coefficient is used to increase friction to slow down the falling speed, giving the filtration a certain amount of time, thereby ensuring the filtration effect.

[0050] This device solves the problem of low efficiency when treating internal impurities in traditional silane tanks.

[0051] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
