Its working principle is to use high frequency and high voltage to discharge corona on the surface of the treated material to oxidize and polarize the surface molecules, increase the surface polarity to increase adhesion. Corona machines are commonly used for traditional rubber, plastic and other film materials. Such film materials involve ink printing, compounding, gluing, coating, bonding and other processes in the application process. These processes require the film surface to have a certain adhesion.

[0033] Example
[0034] Reference Figure 1-Figure 3 As shown, the utility model provides a corona machine, including a placement table 1, a conveying mechanism and a corona mechanism 4, wherein the conveying mechanism and the corona mechanism 4 are both arranged on the placement table 1, the conveying mechanism is sequentially provided with a loading station, a processing station and an unloading station along its conveying direction, and is suitable for conveying the substrate from the loading station to the processing station and the unloading station in sequence, the corona mechanism 4 is arranged above the conveying mechanism and at the processing station, and is suitable for performing electric shock treatment on the substrate conveyed from the loading station to the processing station.
[0035] Through the conveying mechanism, the substrate conveyed to the loading station in the previous link can be automatically conveyed to the corona mechanism 4, and the substrate is subjected to electric shock treatment by the corona mechanism 4. The high-frequency and high-voltage corona mechanism 4 is used to perform corona discharge on the surface of the substrate to be treated, thereby generating low-temperature plasma, causing free radical reaction on the surface of the substrate to cause cross-linking of the polymer. The surface becomes rough and its wettability to polar solvents is increased. These ions enter the surface of the substrate through electric shock and penetration to destroy its molecular structure, thereby oxidizing and polarizing the treated surface molecules, and the ion electric shock erodes the surface, thereby increasing the adhesion ability of the substrate surface. The treated substrate is then moved from the treatment station to the unloading mechanism under the action of the conveying mechanism, and the treated substrate is conveyed to the next link by the unloading mechanism, thereby realizing automatic conveying and electric shock treatment, with a high degree of automation, high work efficiency, reduced labor costs, and avoiding the risk of work-related injuries caused by manual operation.
[0036] Specifically, the conveying mechanism includes a conveyor belt 3 and a driving member. The loading station, the processing station and the unloading station are arranged along the conveying direction of the conveyor belt 3, which is suitable for conveying the substrate from the loading station to the processing station and the unloading station in sequence.

The driving member is arranged at one of the rollers 8, which is suitable for providing power to the conveyor belt 3 to drive the conveyor belt 3 to move, and convey the substrate from the loading station to the processing station and the unloading station in sequence. There is no sole limitation on the structure of the driving member, and it can be set to a driving motor, etc., as long as it can drive the roller 8 to rotate and drive the conveyor belt 3 to move, and move the substrate from the loading station to the processing station and the unloading station in sequence.
[0037] Two bottom plates 2 are arranged above the placement table 1. The bottom plates 2 are respectively located on both sides of the conveyor belt 3.

[0038] As a specific implementation, the corona mechanism 4 includes a discharge plate 41, which is arranged above the conveyor belt 3 at intervals and located at the processing station. There is a space between the discharge plate 41 and the conveyor belt 3 for the substrate to move to the bottom of the discharge plate 41. The discharge plate 41 in the power-on state processes the substrate motor, performs corona discharge on the substrate surface, and increases the adhesion of the substrate surface. As for the number of discharge plates 41, two are provided in this embodiment, and the two discharge plates 41 are arranged along the conveying direction of the conveyor belt 3. By providing two discharge plates 41, firstly, the substrate can be subjected to electric shock treatment, so that the adhesion of the substrate after corona is better. At the same time, it can adapt to substrates with different corona requirements to select one discharge plate 41 or two discharge plates 41 to work. In addition, when one of the discharge plates 41 has a problem, the other discharge plate 41 can continue to work, avoiding stopping work to repair the faulty discharge plate 41.

The corona mechanism 4 also includes a support assembly 42, which is arranged on the bottom plate 2. The support assembly 42 is suitable for supporting the discharge plate 41, limiting the discharge plate 41 above the conveyor belt 3, and supporting and fixing the discharge plate 41 through the support assembly 42.
[0040] Specifically, the support assembly 42 includes a base 421 arranged on the bottom plate 2. There are two bases 421, and the two bases 421 are respectively located on different bottom plates 2. Two vertically arranged connecting rods 422 are arranged on the base 421. Support rods 423 are arranged at the top ends of the two connecting rods 422 of the same base 421.

It can be set to a cylinder or a linear guide rail. As long as it can drive the electric release board 41 to move up and down in the vertical direction, the height of the electric release board 41 can be adjusted to meet the requirements of different product heights.

The bottom plate 2 and the base 421 are sequentially inserted into the first fixing hole 5 and the second fixing hole 6 by means of a latch, so that the bottom plate 2 and the base 421 are detachably connected. The discharge board 41 can be removed from the bottom plate 2 for repair or replacement. In addition, when the position of the discharge board 41 is adjusted, the latch is taken out from the first fixing hole 5 and the second fixing hole 6. At this time, the base 421 and the bottom plate 2 are separated, and the bottom plate 2 can be moved, thereby moving the discharge board 41. After the position of the discharge board 41 on the conveyor belt 3 is adjusted, the latch is taken out again and inserted into the second fixing hole 6 and the first fixing hole 5 to fix the base 421 on the bottom plate 2.
