Description

Technical Field

[0001] This utility model relates to the field of injection molding processing technology, specifically to a surface treatment device for injection molded parts before coating. Background Technology

[0002] Surface treatment of injection molded parts before painting is a crucial step that directly affects the adhesion and coating effect. Cleaning with physical and chemical solvents and adding coatings can greatly improve the coating effect of injection molded parts.

[0003] According to Chinese Patent Publication No. CN222135944U, "A Surface Treatment Equipment for Injection Molded Parts Before Coating," the main description is that, under the control and adjustment of various angles of a six-axis robotic arm, a plasma flame gun can precisely bake various angle positions of the injection molded parts, thereby increasing the surface tension of the injection molded parts. It can also handle injection molded parts with complex structures. The higher the surface tension of the injection molded parts, the stronger the paint adhesion, resulting in a thicker paint film and better quality during coating. When the plasma flame gun reciprocates and bakes at the parting line of the injection molded parts, the surface tension of the parting line and its vicinity reaches more than 70 dynes / cm. This allows for the treatment of parting lines with a height not exceeding 0.05mm, resulting in a thicker paint film at the parting line position, thus covering the parting line. A good coating appearance can be obtained without sanding, thereby reducing the working hours of employees handling parts, eliminating the use of consumable sandpaper, avoiding the consumption of a large amount of sanding tool and labor costs, and eliminating sanding dust on the production site, thus optimizing the production environment.

[0004] Flame treatment can improve paint adhesion on injection molded parts. However, during the injection process, grease, dust, and other impurities can adhere to the injection molded parts, forming a coating on the surface that hinders direct contact between the flame and the surface, resulting in uneven flame treatment.

[0005] Therefore, a surface treatment device for injection molded parts before coating is proposed to solve the problem that grease, dust and other impurities may adhere to the injection molded parts during the injection process, forming a covering on the surface of the injection molded parts, which can hinder the direct contact between the flame and the surface of the injection molded parts, resulting in uneven flame treatment effect. Utility Model Content

[0006] The technical problem to be solved by this utility model is that during the injection molding process, injection molded parts will be contaminated with impurities such as grease and dust, which can form a covering on the surface of the injection molded parts, hindering the direct contact between the flame and the surface of the injection molded parts, resulting in uneven flame treatment effect. Therefore, a surface treatment device for injection molded parts before coating is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a surface treatment device for injection molded parts before coating, including a worktable, a robotic arm and a flame nozzle. A cleaning frame is provided on the worktable, the cleaning frame is filled with cleaning water, a partition is fixedly connected inside the cleaning frame, and two first grooves are provided on the cleaning frame. A first motor is fixedly connected to both sides of the worktable located in the first grooves. A first lead screw is fixedly connected to the output end of the first motor. A moving plate is threadedly connected to the first lead screw. A second motor is fixedly connected to one side of the moving plate. A rotating column is fixedly connected to the output end of the second motor. A rotating plate is fixedly connected to the bottom side of the rotating column. An electric push rod is fixedly connected to the bottom end of the rotating plate. A moving frame is fixedly connected to the output end of the electric push rod. A third motor is fixedly connected to one side of the moving frame. A bidirectional lead screw is fixedly connected to the output end of the third motor. Clamping columns are threadedly connected to both sides of the bidirectional lead screw that are far apart from each other. Limiting recesses are provided on the clamping columns.

[0008] As a preferred technical solution of this utility model, a water pump is fixedly connected to the outside of the cleaning frame, and a horizontal frame is fixedly connected to the inside of the cleaning frame. The output end of the water pump is connected to the inside of the horizontal frame, and nozzles are evenly fixedly connected to the horizontal frame. By pumping water through the horizontal frame and the nozzles, the contact between the cleaning liquid and the injection molded part can be increased, thereby improving the cleaning effect.

[0009] As a preferred technical solution of this utility model, a telescopic motor is fixedly connected to the movable plate, and the output end of the telescopic motor contacts the rotating plate. By setting the telescopic motor and providing a limit on the rotating plate, the stability of the rotating plate can be improved.

[0010] As a preferred technical solution of this utility model, a slider is in contact with the movable plate, and the slider is rotatably embedded in the rotating plate. By setting the slider, the friction between the movable plate and the rotating plate is reduced.

[0011] As a preferred technical solution of this utility model, a folding sleeve is fixedly connected to the bottom end of the rotating plate, and the bottom end of the folding sleeve is fixedly connected to the moving frame. The folding sleeve is located outside the electric push rod. By setting the folding sleeve and the moving frame, the contact between the electric push rod and the cleaning fluid can be reduced.

[0012] This invention has the following advantages: by placing the injection molded part to be treated on the clamping column and flipping it so that the injection molded part comes into contact with the cleaning fluid in the cleaning frame, and then driving the moving frame up and down by the electric push rod, while the water pump draws out the cleaning fluid to increase the contact between the cleaning fluid and the injection molded part, the grease and dust on the surface of the injection molded part can be greatly reduced, thus improving the effect of flame treatment.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3The illustrated surface treatment equipment for injection molded parts before coating includes a worktable 1, a robotic arm 2, and a flame nozzle 3. The flame nozzle 3 is connected to a plasma torch (not shown in the figure). By combining a plasma generator power supply, torch, and cables, an electric arc is generated between the nozzle and electrode inside the torch through arc discharge and plasma generation. This causes air to instantly become ionized as it passes through the torch. Since the pressure of the plasma is much greater than the external atmospheric pressure, the plasma is ejected from the torch as a plasma beam, which can generate a temperature of 9000 degrees Celsius. A cleaning frame 4 is provided on the worktable 1. The cleaning frame 4 contains alcohol and pure water on both sides of a partition 5. The cleaning frame 4 is used to treat oil and dust on the surface of the injection molded parts, while the pure water is used for subsequent cleaning of the alcohol surface. The cleaning frame 4 is filled with cleaning water. A partition 5 is fixedly connected inside the cleaning frame 4. Two first grooves 6 are provided on the cleaning frame 4. A first motor is fixedly connected to both sides of the worktable 1 located in the first grooves 6. The first motor drives the first lead screw 7 to rotate, which causes the moving plate 8 to move within the first groove 6. The output end of the first motor is fixedly connected to the first lead screw 7, and the moving plate 8 is threadedly connected to the first lead screw 7. A second motor is fixedly connected to one side of the moving plate 8. The second motor drives the rotating column 9 to rotate, which causes the rotating plate 10 to rotate. The output end of the second motor is fixedly connected to the rotating column 9, and the rotating plate 10 is fixedly connected to the bottom side of the rotating column 9. An electric push rod 11 is fixedly connected to the bottom end of the rotating plate 10. The electric push rod 11 extends and retracts, which causes the moving frame 12 to vibrate in the cleaning solution. The output end of the electric push rod 11 is fixedly connected to the moving frame 12. A third motor is fixedly connected to one side of the moving frame 12. The third motor drives the bidirectional lead screw 13 to rotate, which causes the clamping column 14 to move relative to each other. The output end of the third motor is fixedly connected to the bidirectional lead screw 13. The two mutually distant sides of the bidirectional lead screw 13 are threadedly connected to the clamping column 14. A limit recess is provided on the clamping column 14, and the limit recess is a right-angled triangle structure.

[0019] A water pump 15 is fixedly connected to the outside of the cleaning frame 4, and a horizontal frame 16 is fixedly connected inside the cleaning frame 4. The output end of the water pump 15 is connected to the inside of the horizontal frame 16. Spray nozzles 17 are evenly fixedly connected to the horizontal frame 16. The water pump 15 draws the cleaning liquid and sprays it out from the spray nozzles 17, which can increase the contact between the cleaning liquid and the injection molded parts and improve the cleaning effect.

[0020] The movable plate 8 is fixedly connected to a telescopic motor 18. The output end of the telescopic motor 18 is in contact with the rotating plate 10. By setting the telescopic motor 18, it can provide a limit by extending, which can facilitate the stable support of the rotating plate 10.

[0021] The movable plate 8 is in contact with a slider 19, which is rotatably embedded in the rotating plate 10. By setting the slider 19, the rotational friction between the movable plate 8 and the rotating plate 10 is reduced.

[0022] The rotating plate 10 is fixedly connected to the bottom end of a folding sleeve 20, and the bottom end of the folding sleeve 20 is fixedly connected to the moving frame 12. The folding sleeve 20 is located outside the electric push rod 11. By setting the folding sleeve 20, the cleaning fluid can be prevented from contacting the electric push rod 11, thereby reducing damage to the electric push rod 11.

[0023] Working principle: The injection molded part to be processed is placed between the clamping columns 14 and limited by the limiting recess. Then, the telescopic motor 18 retracts, the second motor drives the rotating plate 10 to rotate, and the electric push rod 11 extends, allowing the bottom side of the clamping column 14 to enter the water. At the same time, the injection molded part is immersed in the alcohol on the left side of the cleaning frame 4 to clean oil and dust. Then, by the rotation of the first motor and the first lead screw 7, the injection molded part can be moved closer to the pure water on the right side of the cleaning frame 4 to clean the alcohol adhering to the injection molded part. Then, the extension and retraction of the electric push rod 11 generates vibration, and the water pump 15 draws the cleaning liquid and sprays it evenly through the horizontal frame 16 and the nozzle 17 to increase the contact area and achieve the effect of cleaning the injection molded part to be processed. After cleaning, the injection molded part is moved and flipped to be on the upper side of the worktable 1. Then, the surface of the injection molded part is treated by the robotic arm 2 and the flame nozzle 3.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
