Therefore, most medical device manufacturers commonly adopt a process of coating hydrophilic coating by using PVP as a hydrophilic solution and performing the hydrophilic coating in a dip-coating mode, and when the hydrophilic coating is performed, as the guide wire cannot bend, a corresponding length of coated copper is often required to meet the coating requirement, while most devices are often only capable of processing guide wires with the length of 1.5 meters, and taking a dip-coating device for processing guide wires with the length of 1.5 meters as an example, a dip-coating liquid storage tank is about 1.2 meters, which causes that the device is about 3 meters, if a longer guide wire is to be processed, a higher liquid storage tank is required, the height of the device is required to be increased by times, and the cost of the device is increased by times.
There is also the mode that adopts the dip-coating of secondary turn, namely coating once, solidification back, turns around the seal wire again, carries out the dip-coating of secondary, solidification, has caused the loaded down with trivial details of course of working, and efficiency reduces to parameters such as homogeneity and thickness of the coating that forms after the dip-coating respectively are twice can't guarantee the uniformity, cause the quality of final product to reduce, the defective percentage improves.

In addition, in order to prevent the hydrophilic solution from leaking out and affecting the coating effect of the hydrophilic solution on the guide wire caused by the shaking of the dynamic sealing liquid storage tank 3 during the moving process of the dynamic sealing liquid storage tank 3, a guiding structure may be added, for example, a sliding block (not shown in the figure) is further disposed on the dynamic sealing liquid storage tank 3, and the sliding block is slidably disposed on a guide rail (not shown in the figure) in the box body 1.

In particular, when the deformable sealer 4 is driven by air pressure to seal, as shown in fig. 2, at least one air flow channel 6 communicated with the mounting hole 32 is formed at the bottom of the groove-shaped body 31, an air inlet end of the air flow channel 6 is connected with an air supply device (not shown in the figure), and the air flow channel 6 is arranged at the middle position of the deformable sealer 4, so that the middle position of the deformable sealer 4 is deformed, and the positions of the two ends of the deformable sealer are guaranteed to be in sealing connection with the bottom of the dynamic sealing liquid storage tank.
Since the fixture assembly 2 clamps a plurality of guide wires simultaneously for coating, although a certain gap exists between the guide wires, if the guide wires are not limited in the coating process, a certain contact is often generated between adjacent guide wires due to shaking, and the effect of the coating is affected, therefore, in this embodiment, as shown in fig. 2, it is preferable that the dynamic sealing liquid storage tank 3 further comprises a cover plate 33, at least one conical through hole is formed on the cover plate 33, each conical through hole is coaxial with one of the mounting holes 32, a guide device 5 is arranged in the cover plate, a guide hole 51 for the guide wire 10 to pass through and coaxial with one of the mounting holes 32 is formed on the guide device 5, the guide hole 51 is a conical hole with a large upper end and a small lower end, and the small end opening of the guide hole 51 is larger than the diameter of the strip.
