Description

Technical Field

[0001] This utility model relates to the field of debubbling electrophoresis technology, specifically a debubbling electrophoresis device. Background Technology

[0002] Electrophoretic coating is one of the most effective methods for coating metal workpieces. Electrophoretic coating is a special coating method in which a conductive object is immersed in a tank filled with water-diluted electrophoretic coating at a relatively low concentration as the anode (or cathode). A corresponding cathode (or anode) is set in the tank. After a period of time, a uniform and fine coating film that is not dissolved by water is deposited on the surface of the object.

[0003] The existing technology has the following problems: Typically, defoamers are added directly to the electrophoresis pool, resulting in a slow mixing rate between the liquid and the defoamer. This affects the efficiency of bubble elimination within the pool, reducing the quality of the workpiece electrophoresis. Furthermore, when the workpiece is placed in the electrophoresis pool, bubbles easily adhere to its surface, causing uneven coating and ultimately affecting the electrophoresis effect.

[0004] Therefore, this invention provides a degassing electrophoresis device to solve the above problems. Utility Model Content

[0005] This invention provides a degassing electrophoresis device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including an electrophoresis tube and a hybrid structure assembled inside the electrophoresis tube, and a movable structure assembled outside the electrophoresis tube, wherein a base is fixedly connected to the bottom of the electrophoresis tube;

[0007] The hybrid structure includes a reciprocating lead screw mounted on one side of the inner wall of the electrophoresis tube and a servo motor fixedly installed on the top of the base, as well as a first guide wheel fixedly connected to the output end of the servo motor. A belt is sleeved on the surface of the first guide wheel, and a second guide wheel is sleeved on the side of the belt away from the first guide wheel. A cylinder that passes through the electrophoresis tube and is fixedly connected to the bottom of the reciprocating lead screw is fixedly connected to the top of the second guide wheel. A movable block is threadedly connected to the surface of the reciprocating lead screw, and a water collection ring is fixed to the surface of the movable block.

[0008] As a preferred technical solution of this application, a U-shaped rod is rotatably connected to the bottom of the second guide wheel, and the top of the U-shaped rod is fixedly connected to one side of the bottom of the electrophoresis tube.

[0009] As a preferred technical solution of this application, the inner wall of the electrophoresis tube is provided with a limiting groove for the vertical sliding of the movable block, the surface of the water collecting ring is arranged with a plurality of water outlet holes, and the top of the water collecting ring is connected to a water inlet pipe.

[0010] As a preferred technical solution of this application, a fixed rod is fixedly connected to the top of the first guide wheel, extending through the center of the bottom of the electrophoresis tube to its interior, and a stirring blade is fixedly connected to one end of the fixed rod located inside the electrophoresis tube.

[0011] As a preferred technical solution of this application, the movable structure includes a cylinder fixedly installed on the surface of the electrophoresis tube and a filter tube installed inside the electrophoresis tube, as well as two sliding plates slidably connected to both sides of the surface of the electrophoresis tube. The output end of the cylinder is fixedly connected to a connecting block, and the surface of the connecting block is rotatably connected to a guide rod rotatably connected to the surface of the sliding plate.

[0012] As a preferred technical solution of this application, the bottom side of the sliding plate is fixedly connected to the top of the filter cylinder, and the bottom of the sliding plate is provided with an arc-shaped notch that matches the curvature of the electrophoresis cylinder surface.

[0013] As a preferred technical solution of this application, the water collection ring is hollow inside and is located on the inner wall of the electrophoresis tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By employing a hybrid structure, a servo motor drives the first guide wheel to rotate, which in turn causes the second guide wheel and cylinder to rotate via belt drive. This, in turn, drives the reciprocating screw to rotate, causing the movable block to slide vertically along the limiting groove, thus moving the water collecting ring up and down. Liquid is introduced into the water collecting ring through the inlet pipe and sprayed out from the outlet holes in the circumferential array. This up-and-down movement releases defoamer at different heights within the electrophoresis tank, reducing bubble formation. Simultaneously, the fixed rod at the top of the first guide wheel rotates the stirring blades, thoroughly agitating the liquid inside the tank, breaking up bubble buildup, enhancing the defoaming effect, preventing bubbles from interfering with the migration path of electrophoretic substances, and improving the efficiency of bubble elimination within the electrophoresis tank.

[0016] Through the design of the movable structure, the cylinder pushes the connecting block to move, which in turn drives the sliding plate to slide along the surface of the electrophoresis cylinder via the guide rod. This causes the filter cylinder to rotate on the surface of the electrophoresis cylinder, allowing the workpiece inside the filter cylinder to swing, reducing the accumulation of air bubbles within the workpiece and improving the electrophoresis effect. At the same time, the filter cylinder can filter impurities, reducing their impact on the electrophoresis process. It is also easy to remove and clean separately, maintaining the cleanliness of the device and creating favorable conditions for subsequent experiments or production. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] This utility model provides, for example Figure 1-5 The degassing electrophoresis device shown includes an electrophoresis tube 1, a hybrid structure 2 assembled inside the electrophoresis tube 1, and a movable structure 3 assembled outside the electrophoresis tube 1. A base 4 is fixedly connected to the bottom of the electrophoresis tube 1.

[0025] The hybrid structure 2 includes a reciprocating lead screw 201 mounted on one side of the inner wall of the electrophoresis tube 1 and a servo motor 202 fixedly installed on the top of the base 4, as well as a first guide wheel 203 fixedly connected to the output end of the servo motor 202. A belt 204 is sleeved on the surface of the first guide wheel 203. A second guide wheel 205 is sleeved on the side of the belt 204 away from the first guide wheel 203. A cylinder 206 that passes through the electrophoresis tube 1 and is fixedly connected to the bottom of the reciprocating lead screw 201 is fixedly connected to the top of the second guide wheel 205. A movable block 207 is threadedly connected to the surface of the reciprocating lead screw 201. A water collection ring 208 is fixedly fixed to the surface of the movable block 207.

[0026] Using the above scheme, the servo motor 202 is started, driving the first guide wheel 203 to rotate. Through the belt 204, the second guide wheel 205 and the cylinder 206 rotate, which in turn drives the reciprocating screw 201 to rotate. The movable block 207 slides vertically along the limiting groove, causing the water collecting ring 208 to move up and down. The water collecting ring 208 introduces liquid through the inlet pipe 209 and sprays it out through the circumferential array of outlet holes. Combined with its up-and-down movement, it releases defoaming agent at different heights within the electrophoresis tube 1, reducing bubble formation. Simultaneously, the fixed rod at the top of the first guide wheel 203 drives the stirring blades 210 to rotate, thoroughly stirring the liquid inside the tube, breaking up bubble accumulation, further enhancing the defoaming effect, preventing bubbles from interfering with the migration path of substances in electrophoresis, and improving the efficiency of bubble elimination inside the electrophoresis tube 1.

[0027] The bottom of the second guide wheel 205 is rotatably connected to a U-shaped rod, and the top of the U-shaped rod is fixedly connected to one side of the bottom of the electrophoresis tube 1. The inner wall of the electrophoresis tube 1 has a limiting groove for the vertical sliding of the movable block 207. The surface of the water collecting ring 208 has several water outlet holes arranged in a circular array. The top of the water collecting ring 208 is connected to a water inlet pipe 209. The top of the first guide wheel 203 is fixedly connected to a fixing rod that penetrates from the center of the bottom of the electrophoresis tube 1 to its interior. One end of the fixing rod located inside the electrophoresis tube 1 is fixedly connected to a stirring blade 210. The movable structure 3 includes components fixedly installed on the surface of the electrophoresis tube 1. The cylinder 301 and the filter cylinder 302 installed inside the electrophoresis tube 1, as well as two sliding plates 303 slidably connected to both sides of the surface of the electrophoresis tube 1, are provided with a connecting block 304 fixedly connected to the output end of the cylinder 301. A guide rod 305 rotatably connected to the surface of the sliding plate 303 is rotatably connected to the surface of the connecting block 304. The bottom side of the sliding plate 303 is fixedly connected to the top of the filter cylinder 302. The bottom of the sliding plate 303 is provided with an arc-shaped notch that matches the curvature of the surface of the electrophoresis tube 1. The water collecting ring 208 is hollow inside and is located on the inner wall of the electrophoresis tube 1.

[0028] Using the above scheme, the cylinder 301 pushes the connecting block 304 to move, and the guide rod 305 drives the sliding plate 303 to slide along the surface of the electrophoresis cylinder 1, causing the filter cylinder 302 to rotate back and forth on the surface of the electrophoresis cylinder 1. This causes the workpiece placed inside the filter cylinder 302 to swing, reducing the accumulation of air bubbles in the workpiece and thus improving the electrophoresis effect. At the same time, the filter cylinder 302 can filter impurities, reducing their impact on the electrophoresis process, and is easy to remove and clean separately, maintaining the cleanliness of the device and providing good conditions for subsequent experiments or production.

[0029] The working principle of a degassing electrophoresis apparatus based on an embodiment is as follows: First, the apparatus performs pretreatment and sample placement. The cylinder 301 is activated, and its output pushes the connecting block 304 to move. The connecting block 304, through a guide rod 305 rotatably connected to its surface, drives two sliding plates 303 to slide along the surface of the electrophoresis cylinder 1. Since one side of the bottom of the sliding plate 303 is fixedly connected to the top of the filter cylinder 302, the filter cylinder 302 rises with the sliding plate 303, allowing the workpiece to be electrophoresed to be placed inside the filter cylinder 302. Subsequently, the cylinder 301 is controlled to retract, and the connecting block 304 pulls the sliding plate 303 back to its original position via the guide rod 305. The filter cylinder 302 then descends to a suitable position inside the electrophoresis cylinder 1, with the arc-shaped notch at the bottom of the sliding plate 303 fitting against the surface of the electrophoresis cylinder 1, ensuring stable placement of the filter cylinder 302.

[0030] Next, the hybrid structure 2 is activated to perform the defoaming operation. The servo motor 202 is turned on, and its output drives the first guide wheel 203 to rotate. The first guide wheel 203, via the belt 204, causes the second guide wheel 205 to rotate. The cylinder 206 at the top of the second guide wheel 205 rotates accordingly, thereby driving the reciprocating screw 201 on one side of the inner wall of the electrophoresis tube 1 to rotate. The movable block 207, threaded onto the surface of the reciprocating screw 201, slides vertically along the limiting groove on the inner wall of the electrophoresis tube 1, causing the water collecting ring 208 on the surface of the movable block 207 to move up and down. Simultaneously, defoamer is introduced into the water collecting ring 208 through the water inlet pipe 209. The water collecting ring 208 has a hollow internal structure, and the defoamer is evenly sprayed out through the circumferential array of water outlets on its surface. Combined with the up-and-down movement of the water collecting ring 208, defoamer is released into different height areas within the electrophoresis tube 1, reducing bubble formation. During this process, the fixed rod at the top of the first guide wheel 203 drives the stirring blade 210 to rotate inside the electrophoresis tube 1, which fully stirs the liquid inside the tube, breaks up the bubble accumulation, and further enhances the defoaming effect.

[0031] During electrophoresis, the mixing structure 2 can be continuously activated as needed to ensure that air bubbles inside the cylinder are eliminated in a timely manner. If it is necessary to adjust the position of the workpiece to reduce air bubble accumulation, the cylinder 301 can be restarted, and the guide rod 305 drives the sliding plate 303 to make the filter cylinder 302 rotate back and forth inside the electrophoresis cylinder 1. The workpiece swings with the filter cylinder 302, reducing the probability of air bubbles accumulating on or inside the workpiece surface.

[0032] After electrophoresis is completed, the servo motor 202 and cylinder 301 are turned off, and the filter cylinder 302 is raised to remove the workpiece. The filter cylinder 302 can then be removed separately for cleaning to maintain the cleanliness of the device and prepare for the next experiment or production.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
