Description

Technical Field

[0001] This utility model relates to the field of corona treatment technology, and in particular to a curved surface corona treatment machine with adjustable electrodes. Background Technology

[0002] The curved surface corona treatment machine is a special equipment used to process the surface energy of three-dimensional curved objects. With the diversification of industrial products, the demand for surface treatment of three-dimensional curved workpieces (such as automotive parts, appliance housings, and containers) is increasing. When processing such curved surfaces, existing equipment cannot maintain a constant distance between the electrode and the curved surface, which leads to uneven discharge during the movement process, poor treatment effect, obvious blind spots and weak areas, and seriously affects product quality.

[0003] Furthermore, for workpieces with different radii of curvature, it is necessary to frequently change the position of the corresponding workpiece to face the corona treatment machine. Since the position of the corona treatment machine is fixed, when the corresponding workpiece is rotated, the change of different positions of the workpiece also requires timely fine-tuning of the distance between the workpiece and the corona treatment machine. However, there is no relevant equipment in the existing technology for fine-tuning the distance. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing equipment, when processing such curved surfaces, cannot maintain a constant distance between the electrode and the curved surface, resulting in uneven discharge and poor processing effect during movement. Therefore, this invention proposes a curved surface corona treatment machine with adjustable electrodes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable electrode curved surface corona treatment machine includes a support frame and a drive motor. The drive motor is installed at the bottom of the support frame. An electrode corona treatment machine and a curved panel are placed on the support frame. The electrode corona treatment machine slides on the support frame via the drive motor. The curved panel slides on the support frame via a second sliding block. The second sliding block is provided with a rolling displacement part for clamping and moving the curved panel.

[0006] Preferably, the support frame has a sliding hole, a first sliding block slides on the sliding hole, a rotating screw is coaxially fixed to the output end of the drive motor, the rotating screw is threadedly connected to the first sliding block, and the electrode corona generator is installed on the first sliding block.

[0007] Preferably, the support frame is provided with a sliding groove, the second sliding block slides on the support frame through the sliding groove, the support frame is fixed with a baffle, and a compression spring is connected between the second sliding block and the baffle.

[0008] Preferably, the second sliding block is provided with an elastic clamping block, which is disposed between the electrode corona machine and the curved panel and is used to elastically abut against the curved panel.

[0009] Preferably, the tumbling displacement part includes a friction wheel and a rotating wheel. The rotating wheel is mounted on the second sliding block via a drive shaft. A base is provided on the top of the elastic clamping block. The friction wheel is mounted on the base via a fixed shaft. The friction wheel and the rotating wheel abut against the two sides of the curved panel, respectively.

[0010] Preferably, the support frame is further provided with a top rod, and the top rod abuts against the second sliding block through a threaded assembly.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model changes the position of the first sliding block on the support frame, and at the same time can drive the distance between the electrode corona machine installed on the first sliding block and the curved panel, thereby ensuring that the electrode of the electrode corona machine and the surface of the workpiece on the curved panel always maintain a constant and optimal processing distance.

[0012] 2. This utility model drives the rotation of the rotating wheel, which, in conjunction with the opposing friction wheel, causes the curved panel to rotate due to friction, changing the position of the curved panel toward the side of the electrode corona machine, thereby completing the position switching of the curved panel and the position switching of the surface treatment.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-5 An adjustable electrode curved surface corona treatment machine includes a support frame 1 and a drive motor 3. The drive motor 3 is fixedly installed at the bottom of the support frame 1. An electrode corona treatment machine 6 and a curved panel 7 are placed on the support frame 1. A sliding hole 2 is provided on the support frame 1, and a first sliding block 5 slides on the sliding hole 2 to provide conditions for the sliding of the first sliding block 5 on the support frame 1.

[0017] The electrode corona treatment machine 6 slides on the support frame 1 via a drive motor 3. A rotating lead screw 4 is coaxially fixed to the output end of the drive motor 3, and the lead screw 4 is threadedly connected to a first sliding block 5. The electrode corona treatment machine 6 is mounted on the first sliding block 5. Therefore, when the drive motor 3 is turned on, it drives the rotating lead screw 4 to rotate, thereby changing the position of the first sliding block 5 on the support frame 1. Simultaneously, it can adjust the distance between the electrode corona treatment machine 6 mounted on the first sliding block 5 and the curved panel 7. This ensures that the electrodes of the electrode corona treatment machine 6 maintain a constant and optimal processing distance from the surface of the workpiece on the curved panel 7. The electrode corona treatment machine 6 uses a high-frequency, high-voltage electric field to ionize the air near the electrodes, generating low-temperature plasma. This plasma bombards the material surface, increasing its surface energy through physical and chemical interactions, thereby improving its wettability and adhesion. This technology is existing and will not be elaborated upon further here.

[0018] The curved panel 7 slides on the support frame 1 via the second sliding block 9, thus enabling the curved panel 7 to achieve secondary distance adjustment during the corona discharge process.

[0019] Furthermore, a sliding groove 11 is provided on the support frame 1, and the second sliding block 9 slides on the support frame 1 through the sliding groove 11. A baffle 17 is fixed on the support frame 1, and a compression spring 18 is connected between the second sliding block 9 and the baffle 17. Therefore, the curved panel 7 placed on the second sliding block 9 will tend to be pushed towards the electrode corona machine 6 under the compression action of the compression spring 18.

[0020] Reference Figure 2 As shown, the second sliding block 9 is provided with an elastic clamping block 10. The elastic clamping block 10 is located between the electrode corona machine 6 and the curved panel 7, and is used to elastically abut against the curved panel 7. The second sliding block 9 is L-shaped, and under the action of the elastic clamping block 10, the curved panel 7 is fastened to the outer surface of the rotating wheel 15, providing a pushing force for clamping the curved panel 7.

[0021] The second sliding block 9 is provided with a tumbling displacement part for clamping and moving the curved panel 7. The tumbling displacement part includes a friction wheel 14 and a rotating wheel 15. The rotating wheel 15 is mounted on the second sliding block 9 via a drive shaft 16. The top of the elastic clamping block 10 is provided with a base 12. The friction wheel 14 is mounted on the base 12 via a fixed shaft 13. The friction wheel 14 and the rotating wheel 15 abut against the two sides of the curved panel 7 respectively. The second sliding block 9 is provided with a micro motor. The output end of the micro motor is coaxially fixed with the drive shaft 16. Therefore, under the action of the elastic clamping block 10, the friction wheel 14 is driven to abut against the curved panel 7. So after the micro motor is turned on, it drives the rotating wheel 15 to rotate. With the abutting friction wheel 14, the curved panel 7 can be moved by friction, so that the position of the curved panel 7 toward the side of the electrode corona machine 6 is changed, thereby completing the position switching of the curved panel 7 and the position switching of the surface treatment.

[0022] Furthermore, the support frame 1 is also equipped with a top rod 8, and the top rod 8 abuts against the second sliding block 9 through a threaded assembly. Therefore, when it is necessary to focus on corona treatment on a specific area during operation, it is only necessary to drive the top rod 8 to rotate through the external drive mechanism, so that the position of the second sliding block 9 against the top rod 8, which was originally pushed by the compression spring 18, is changed, without changing the position of the electrode corona treatment machine 6, thereby completing the fine adjustment of the distance between the second sliding block 9 and the electrode corona treatment machine 6.

[0023] The functional principle of this utility model can be explained through the following operation methods: First, after the drive motor 3 is turned on, it drives the rotating lead screw 4 to rotate, thereby changing the position of the first sliding block 5 on the support frame 1. At the same time, it can also drive the distance between the electrode corona machine 6 installed on the first sliding block 5 and the curved panel 7, so that for the workpiece on the curved panel 7, the electrode of the electrode corona machine 6 and the surface of the workpiece on the curved panel 7 always maintain a constant and optimal processing distance.

[0024] Then, after the micro motor is turned on, it drives the rotating wheel 15 to rotate. In conjunction with the friction wheel 14, it can drive the curved panel 7 to rotate due to friction, so that the curved panel 7 changes its position toward the electrode corona machine 6. This completes the position switching of the curved panel 7 and the position switching of the surface treatment. At the same time, the external drive mechanism drives the push rod 8 to rotate, so that the position of the second sliding block 9 against the push rod 8, which was originally pushed by the compression spring 18, changes without changing the position of the electrode corona machine 6. This completes the fine adjustment of the distance between the second sliding block 9 and the electrode corona machine 6.

[0025] 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.
