Abstract
Description
Technical Field
[0001] The invention relates to the technical field of electrodeposition, and in particular to an automated conveying device and method during the electrodeposition process of a pump barrel workpiece. Background Art
[0002] At present, most oil fields at home and abroad use rod pumping systems, which mainly include pumping units, sucker rods and oil pumps. The oil pump is installed in the underground wellbore and is an important part of the system, while the pump barrel is one of the most core components of the oil pump.
[0003] In the environment of high temperature and corrosive well fluid at the bottom of the well, the inner surface of the pump barrel rubs back and forth with the plunger during operation, which places high demands on corrosion resistance and wear resistance. The outer surface of the pump barrel is immersed in the well fluid, which places high demands on corrosion resistance. Electrodeposition is performed on the inner and outer surfaces of the pump barrel to form an electroplated coating containing nickel elements, which can effectively improve the wear resistance and corrosion resistance of the pump barrel and has a good effect.
[0004] Ordinary oil pump barrels are slender workpieces with an outer diameter of 50 to 100 mm and a length of 7-10 m. In current electroplating equipment, except for the oil tank, etching tank, and electroplating tank, which are placed independently on the ground, operators use cranes to lift and move the pump barrel workpiece. However, in the actual operation of manual lifting, there are the following technical difficulties: Since the pump barrel workpiece is slender, it shakes severely during the lifting process, and it is difficult for one person to lift it. The hook hanging operation needs to be done manually, which is labor-intensive and inefficient; when manual lifting is used, the surface of the pump barrel workpiece comes into contact with human hands, which is easy to cause contamination of the surface of the pump barrel workpiece, and the liquid in the pump barrel workpiece cannot be completely discharged, making it difficult to ensure the quality of the electrodeposited layer. Summary of the invention

The controller controls the horizontal slide to pause directly above each slot by receiving the position sensor signal.
[0010] Furthermore, the monitor includes a video monitor for detecting the rotation angle of the movable hook, which is arranged on the horizontal slide and is offset from the lateral position of the movable hook.

[0013] Based on the above-mentioned conveying method of the conveying automation device in the process of electroplating of a pump barrel workpiece, it includes the following steps: (1) The lifting mechanism drives the lifting frame to rise from the ground, driving the pump barrel workpiece to rise until it is roughly flush with each groove; (2) The horizontal slide and the movable hook cooperate to transport the pump barrel workpiece from the lifting frame to the degreasing tank and the etching tank respectively, complete the degreasing and etching of the pump barrel workpiece, and then transport it to each electrodeposition tank respectively; the degreasing tank pre-treats the inner hole surface of the pump barrel workpiece before electrodeposition to remove the oil stains on the surface of the pump barrel workpiece; the etching tank pre-treats the inner hole surface of the pump barrel workpiece before electrodeposition to form an etching surface suitable for electrodeposition; (3) Each electrodeposition tank simultaneously performs electrodeposition on the outer surfaces of multiple pump barrel workpieces; the electrodeposition tank transports electrodeposition liquid to the inner holes of the pump barrel workpieces to form an electrodeposition layer on the inner hole surface of the pump barrel workpiece; (4) According to the progress of electrodeposition, the pump barrel workpieces that have completed electrodeposition in different electrodeposition tanks are transported to the water washing tank behind the electrodeposition tank for water washing, and then transported to the lifting frame through the horizontal slide and sent back to the ground; (5) The horizontal slide transports the pump barrel workpiece, which is degreased and etched in turn and then sent to the empty electrodeposition tank.

Example 5
[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A conveying method of a conveying automation device in a pump barrel workpiece electrodeposition process based on the above embodiments includes the following steps: (1) The lifting mechanism drives the lifting frame 6 to rise from the ground, driving the pump barrel workpiece 19 to rise to be roughly flush with each groove; (2) The horizontal slide 9 cooperates with the movable hook 10 to transport the pump barrel workpiece 19 from the lifting frame 6 to the degreasing tank 2 and the etching tank 3, respectively, to complete the degreasing and etching of the pump barrel workpiece 19, and then transport it to each electrodeposition tank 4 respectively; the degreasing tank 2 pre-treats the inner hole surface of the pump barrel workpiece 19 before electrodeposition to remove the oil stains on the surface of the pump barrel workpiece 19; the etching tank 3 pre-treats the inner hole surface of the pump barrel workpiece 19 before electrodeposition to form an etching surface suitable for electrodeposition; (3) Each electrodeposition tank 4 simultaneously performs electrodeposition on the outer surfaces of multiple pump barrel workpieces 19; the electrodeposition tank 4 delivers electrodeposition liquid to the inner hole of the pump barrel workpiece 19 to form an electrodeposition layer on the inner hole surface of the pump barrel workpiece 19; (4) According to the progress of electrodeposition, the pump barrel workpiece 19 that has completed electrodeposition in different electrodeposition tanks 4 is transported to the water washing tank 5 behind the electrodeposition tank 4 for water washing, and then transported to the lifting frame 6 through the horizontal slide 9 and sent back to the ground; (5) The horizontal slide 9 transports the pump barrel workpiece 19, which is degreased and etched in turn and then transported to the empty electrodeposition tank 4.
[0026] In the above steps, the state change of the pump barrel workpiece 19 is an important link: When the pump barrel workpiece 19 runs between the grooves, the movable rods of the left cylinder 15.1 and the right cylinder 15.2 are both in a short extended posture, and the pump barrel workpiece 19 is in a horizontal state.
[0027] During the electrodeposition process on the inner surface of the pump barrel workpiece 19, the degreasing, etching, electrodeposition and cleaning processes of the inner wall of the pump barrel workpiece 19, the degreasing liquid, etching liquid, electrodeposition liquid and cleaning liquid must enter the pump barrel workpiece 19. Since the pump barrel workpiece 19 is slender and horizontal, the internal liquid is difficult to be discharged quickly and completely, and is easily brought into the next process with the pump barrel workpiece 19. Therefore, when the pump barrel workpiece 19 leaves each groove, the pump barrel workpiece 19 should be in a state of changing from a horizontal state to an inclined state, so that the internal liquid can be discharged quickly and completely, avoiding the internal liquid being brought into the next process with the pump barrel workpiece 19, thereby avoiding liquid contamination of subsequent processes. Specifically, if the active rod of the left cylinder 15.1 is in a short extended position and the active rod of the right cylinder 15.2 is in a long extended position, the pump barrel workpiece 19 is transformed into an inclined state with the right end lowered, and the liquid is discharged outward from the right end of the pump barrel workpiece 19; if the active rod of the left cylinder 15.1 is in a long extended position and the active rod of the right cylinder 15.2 is in a short extended position, the pump barrel workpiece 19 is transformed into an inclined state with the left end lowered, and the liquid is discharged outward from the left end of the pump barrel workpiece 19.
