Description

Technical Field

[0001] The invention mainly relates to the field of acid and alkali cleaning, and in particular to an automated production line for acid and alkali cleaning. Background Art

[0002] Acid-base cleaning is a method of removing dirt from the surface of an object using acidic and alkaline chemicals. Acidic cleaning agents are mainly used to remove inorganic salt scale, alkaline oxides and hydroxides on the metal surface. Commonly used acids include hydrochloric acid, sulfuric acid, nitric acid, etc. Acidic cleaning agents can not only dissolve dirt, but also convert metal rust into salts that are easily soluble in water through acid-base neutralization reactions. When using acidic cleaning agents, you need to pay attention to their corrosiveness to metals, especially their limited applicability to stainless steel and aluminum alloys; When the workpiece enters and leaves the acid-base cleaning tank, an electric hoist is used to assist in lifting and transporting. The lifting hook is manually operated to load and unload the material. The operator is close to the tank. The acid-base tank is heated by a heating wire to allow the acid etching solution to react more fully with the workpiece. The remaining residue in the acid-base tank needs to be manually assisted to neutralize the acid and alkali so that the residue after the reaction meets the treatment standard.

[0003] The inventor discovered the following defects during the operation of the specific embodiment: The existing equipment is a semi-automatic line, and manual operation and the existing structure have safety risks. When the workpiece is placed in and taken out of the acid and alkali cleaning tank, an electric hoist is used to assist in lifting and transportation. The lifting hook is manually operated to load and unload materials. During the operation, the tooling basket will swing, and there is a risk of liquid splashing, which poses certain safety hazards to personnel. There is no accurate numerical reflection of the acid and alkali concentration of the tank. It relies on experience and human subjective evaluation. The heating of the tank is heated by a heating wire to allow the acid etching solution to react more fully to the workpiece. However, the use of heating wires in the pickling tank will have the risk of conductivity. The remaining residue in the acid and alkali tank requires manual assistance for acid and alkali neutralization. Because the residue has too much water, the environmental protection utilization rate is low. After the workpiece is cleaned with acid and alkali solutions, the residual solution on the cleaning surface still needs to be manually handled.

[0004] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Summary of the invention

[0005] 1. Technical problem to be solved by the invention: The present invention provides an automated acid-base cleaning line to solve the technical problems existing in the above-mentioned background technology.

[0006] 2. Technical solution: To achieve the above object, the technical solution provided by the present invention is: an automated production line for acid and alkali cleaning, comprising a travel track, a cleaning tank is arranged on the inner side of the travel track, drying tables are arranged at both ends of one side of the travel track, a neutralization tank is arranged in the middle of one side of the travel track, a liquid level switch is arranged inside the cleaning tank, and a gantry upper rail type travel two-handed mechanical arm is arranged on the top of the travel track; A basket, wherein the basket is arranged at the bottom of the two-handed mechanical arm of the gantry upper rail type crane; A soaking tank is arranged directly below the vehicle track, the number of the soaking tanks is set to be multiple, a pH meter is arranged on one side of the top of the soaking tank, a bubbler tube is arranged inside the soaking tank, a heating tube is arranged at the bottom of the inner wall of the soaking tank, and a water inlet pipe is arranged inside the soaking tank.

[0007] Furthermore, guide rail bodies are arranged on both sides of the top of the traveling track, and a gantry-type traveling two-handed mechanical arm is arranged between the two guide rail bodies.

[0008] Furthermore, the gantry rail-type two-handed robotic arm includes a moving frame, the number of the moving frames is set to two, a first driving motor is arranged on one side between the two moving frames, the internal rotation of the first driving motor is connected to a first transmission shaft, moving wheels are arranged at both ends of the first transmission shaft, and a second driving motor is arranged on the other side between the two moving frames.

[0009] Furthermore, a support frame is provided between the two moving frames, the support frame is connected to the second driving motor, and the second driving motor is internally rotatably connected to the second transmission shaft.

[0010] Furthermore, the number of the sprocket bodies is set to two groups, one group of the sprocket bodies is rotatably connected to the top and bottom of the mobile frame, the sprocket body at the top of the mobile frame is connected to the second transmission shaft, and a chain is set between the two sprocket bodies.

[0011] Furthermore, a linear guide rail is arranged in the middle of the movable frame, the number of the linear guide rails is set to two, and a lifting frame is arranged between the two linear guide rails.

[0012] Furthermore, lifting frames are arranged on both sides of the top of the lifting frame, the connecting frame is slidably connected to the linear guide rail, and hooks are arranged at the four corners of the bottom of the lifting frame.

[0013] Furthermore, an outer wall of the driving track is provided with a pneumatic diaphragm pump, and a pump tube is provided inside the pneumatic diaphragm pump.

[0014] 3. Beneficial effects: Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: The present invention puts the workpiece to be processed into a basket, which is pulled up by a gantry upper rail type traveling two-handed mechanical arm, and then horizontally runs on the traveling track to a designated soaking tank and puts it in. When the soaking time is reached, it is pulled out by a gantry upper rail type traveling two-handed mechanical arm, and horizontally moved to a cleaning tank. After the soaking time is completed, it is pulled out by a gantry upper rail type traveling two-handed mechanical arm and horizontally moved to a cleaning tank. After two water washes, it is pulled out and moved to a material discharge port. The basket is manually moved to a material area, and the acid and alkali cleaning process flow is completed. The soaking tank uses steam as energy supply, and the heating tube is used as energy storage and transmission. Steam heating is used to allow the acid and alkali solutions to fully react. The steam heating temperature is monitored and controlled by a thermocouple. A bubbler tube is added to the soaking tank to allow the solution to flow in the tank while soaking. The pH meter detects the solution concentration in real time and dilutes the solution to the pH value required by the process in combination with the water inlet pipe. If the pH value of the solution in the soaking tank can no longer meet the requirements for cleaning the workpiece, the solution is transferred from the soaking tank to the neutralization tank for acid-base neutralization reaction. The gantry rail-mounted two-handed robotic arm has higher stability than the electric hoist lifting method on the market. The solution ratio in the tank is detected in real time by a pH meter, and the pH value is more accurate, which increases the utilization rate of the workpiece cleaning solution. Steam is used as the medium, and the acid and alkali solutions are heated by steam heating coils to replace the existing heating wire method, avoiding the risk of leakage and improving the safety factor. The remaining residue after acid and alkali neutralization is dried with steam to improve environmental protection utilization. BRIEF DESCRIPTION OF THE DRAWINGS
