[0025] Please refer to Figures 1-5 The utility model provides a technical scheme: a novel aluminum substrate electroplating oxidation equipment, including electroplating bath 1, the surface of electroplating bath 1 is fixedly connected with two portal frames one 7, the surface of two portal frames one 7 is fixedly connected with portal frame two 11, the inner wall of two portal frames two 11 is rotatably connected with outer shaft 13, the surface of one of portal frame two 11 is fixedly installed with motor 12, the output shaft of motor 12 is fixedly connected with outer shaft 13, outer shaft 13 penetrates the surface of portal frame one 7, the inside of outer shaft 13 is slidably connected with inner shaft 10, the surface of outer shaft 13 is provided with chute 14, chute 14 is spiral, the surface of inner shaft 10 is fixedly installed with clamping block 20, clamping block 20 is slidably connected with chute 14, the end of inner shaft 10 away from motor 12 is fixedly connected with hanger 15, hanger 15 is L-shaped, the surface of hanger 15 is fixedly connected with support plate 16, the surface of support plate 16 is fixedly connected with spring one 17, the end of spring one 17 away from support plate 16 is fixedly connected with push plate 18, the surface of push plate 18 is slidably connected with hanger 15, the surface of two outer shafts 13 is fixedly provided with belt pulley, and the structure on two outer shafts 13 is identical, two outer shafts 13 are drivenly connected with belt 6 through belt pulley.

[0026] When the aluminum substrate needs to be electroplated, the sliding push plate 18 is extruded against the spring 17, and the aluminum substrate is placed on the surface of the hanger 15. At this time, the push plate 18 is released, and the spring 17 drives the push plate 18 to reset by the elastic force. The push plate 18 extrudes the aluminum substrate, and the aluminum substrate is clamped to the middle by the push plate 18 and one side of the hanger 15. The motor 12 is started to drive the outer shaft 13 to rotate. The outer shaft 13 drives the sliding groove 14 to rotate when it rotates. The sliding groove 14 extrudes the clamping block 20, and the clamping block 20 drives the inner shaft 10 to slide along the sliding groove 14. When the clamping block 20 slides to the other end of the sliding groove 14, the clamping block 20 is blocked by the sliding groove 14. The outer shaft 13 drives the sliding groove 14 and the inner shaft 10 to rotate when it rotates. This structure can simply and conveniently install and fix the aluminum substrate when it needs to be electroplated. After starting the motor 12, the aluminum substrate will be lowered into the electroplating tank 1 to electroplate the aluminum substrate. The electroplating liquid in the electroplating tank 1 is stirred during rotation. The stirring of the electroplating liquid can reduce the concentration difference between the anode and the cathode, increase the brightness of the plating layer, and avoid local overheating of the aluminum substrate during electroplating.

[0027] The inner wall of the gantry 7 is fixedly connected with a fixed frame 22, the inner wall of the fixed frame 22 is fixedly connected with a spring 21, and the end away from the inner wall of the fixed frame 22 of the spring 21 is fixedly connected with a sliding block 19. The sliding block 19 is a right trapezoid, and the sliding block 19 and the inner wall of the fixed frame 22 are slidably connected.

[0028] When the outer shaft 13 rotates forward, the outer shaft 13 drives the sliding groove 14 to rotate, and the clamping block 20 drives the inner shaft 10 to slide downward along the sliding groove 14. When the clamping block 20 slides to the lowermost end of the sliding groove 14, the sliding groove 14 blocks the clamping block 20. When the clamping block 20 cannot descend, the sliding groove 14 drives the clamping block 20 to rotate when it rotates. The clamping block 20 extrudes the inclined surface of the sliding block 19 when it rotates, so that the sliding block 19 slides into the inside of the fixed frame 22. The sliding block 19 extrudes the spring 21 when it slides. When the clamping block 20 no longer extrudes the sliding block 19, the spring 21 releases the elastic force to drive the sliding block 19 to reset. Conversely, when the outer shaft 13 reverses, the clamping block 20 is blocked by the sliding block 19. At this time, the clamping block 20 is extruded by the sliding groove 14 and slides upward along the sliding groove 14 until it slides to the uppermost end of the sliding groove 14. This structure can block the clamping block 20 when it slides to the uppermost end. At this time, the aluminum substrate on the surface of the hanger 15 can be disassembled or installed. The hanger 15 is prevented from sliding into the electroplating tank 1 due to gravity, and the worker is facilitated to operate.

[0029] A circulation tank 2 is fixedly connected to one side of the electroplating tank 1. A cover plate 3 is fixedly installed on the surface of the circulation tank 2. A pipe 4 is fixedly connected to one side of the circulation tank 2. The circulation tank 2 and the pipe 4 are internally connected. The pipe 4 is L-shaped. A water pump 5 is fixedly installed on the side of the electroplating tank 1 near the circulation tank 2. The inlet and outlet of the water pump 5 are fixedly connected to the end of the pipe 4 away from the circulation tank 2 and the surface of the electroplating tank 1, respectively. A connection port 9 is opened on the side of the electroplating tank 1 near the circulation tank 2. The electroplating tank 1 and the circulation tank 2 are connected through the connection port 9. A filter screen 8 is fixedly connected to the outlet of the water pump 5.

[0030] The electroplating solution inside the electroplating tank 1 flows into the circulation tank 2 through the connection port 9. At this time, the water pump 5 is started, and the water pump 5 draws the electroplating solution inside the circulation tank 2 through the pipe 4, so that the electroplating solution flows back into the electroplating tank 1 through the filter screen 8 and the outlet of the water pump 5. This structure can circulate and filter the electroplating solution inside the electroplating tank 1 to prevent the electroplating solution inside the electroplating tank 1 from becoming too turbid. The filtration makes the electroplating solution achieve a better electroplating effect, thereby reducing the occurrence of burrs on the aluminum substrate after electroplating due to excessive turbidity of the electroplating solution. When the upper hanger 15 rotates, it stirs the electroplating solution to prevent impurities from settling at the bottom of the electroplating tank 1. At this time, the electroplating solution can be circulated and filtered more effectively.

[0031] Working principle: When the aluminum substrate needs to be electroplated, the sliding push plate 18 is used to press the spring 17, placing the aluminum substrate on the surface of the hanger 15. When the push plate 18 is released, the spring 17 uses its elasticity to push the push plate 18 back to its original position. The push plate 18 presses the aluminum substrate, which is then clamped and fixed in the middle by the push plate 18 and one side of the hanger 15. The motor 12 is started, which drives the outer shaft 13 to rotate. When the outer shaft 13 rotates, it drives the slide groove 14 to rotate, pressing the locking block 20. The locking block 20 drives the inner shaft 10 to slide along the slide groove 14. When the locking block 20 slides to the other end of the slide groove 14, it is blocked by the slide groove 14. At this time, the rotation of the outer shaft 13 drives the slide groove 14 and the inner shaft 10 to rotate.

[0032] When the outer shaft 13 rotates forward, the outer shaft 13 drives the sliding groove 14 to rotate, at this time, the clamping block 20 drives the inner shaft 10 to slide downward along the sliding groove 14, when the clamping block 20 slides to the lowermost end of the sliding groove 14, at this time, the sliding groove 14 blocks the clamping block 20, when the clamping block 20 cannot descend, the sliding groove 14 drives the clamping block 20 to rotate when rotating, at this time, the clamping block 20 extrudes the inclined surface of the sliding block 19 when rotating, so that the sliding block 19 slides into the inside of the fixed frame 22, the sliding block 19 extrudes the spring 21 when sliding, when the clamping block 20 no longer extrudes the sliding block 19, the spring 21 releases the elastic force to drive the sliding block 19 to reset, on the contrary, when the outer shaft 13 reverses, the clamping block 20 is blocked by the sliding block 19, at this time, the clamping block 20 is extruded by the sliding groove 14 to slide upward along the sliding groove 14, until sliding to the uppermost end of the sliding groove 14.

[0033] The electroplating solution in the electroplating tank 1 flows into the inside of the circulating tank 2 through the connecting port 9, at this time, the water pump 5 is started, the water pump 5 draws the electroplating solution in the circulating tank 2 through the pipeline 4, so that the electroplating solution flows into the inside of the electroplating tank 1 again through the filter screen 8 and the outlet of the water pump 5.

[0034] The above has made a detailed description on the embodiments of the utility model in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, within the knowledge range possessed by the ordinary skilled in the art of the technical field, various changes can also be made without departing from the purpose of the utility model.
