The present invention relates to a wiper blade coating apparatus.

As is well known, a wiper is a device installed on a windshield or rear window of various vehicles to clean a glass to secure a driver's watch in the rain or snow.

Here, the wiper may be divided into a wiper blade, a wiper arm, an electric motor, a link mechanism, and the wiper blade is made of a soft rubber material as a part directly contacting the glass surface.

1A is a perspective view illustrating a representative example of a conventional wiper blade.

Referring to FIG. 1A, the wiper blade 100 is a strip having a connection portion 110 connected to a wiper arm (not shown) and first and second inclined surfaces 120a and 120b in direct contact with the glass surface. It is composed of a portion 120, the elastic portion 130 for connecting the connecting portion 110 and the strip portion 120. Such wiper blades 100 are consumables. When the first and second inclined surfaces 120a and 120b of the strip part 120 are badly worn during long-term use, the wiper blade 100 may be degraded as the performance thereof is significantly degraded. Should be replaced. Accordingly, in order to extend the life of the wiper blade 100, the wiper blade 100 may be made of a material having excellent wear resistance, or the wear resistance may be improved on the first and second inclined surfaces 120a and 120b of the strip part 120. Forming a coating film, such as a carbon coating film.

Figure 1b is a plan view for explaining a conventional wiper blade coating apparatus, Figure 1c is a configuration diagram for schematically illustrating a state in which the coating liquid is sprayed on the wiper blade in the conventional wiper blade coating apparatus.

Such wiper seating groove (H) is arranged in the same pitch as the conveying pitch of the pallet 220. And, the injection unit 230 for performing a linear motion by the linear transfer module 240 is installed in the center of the upper surface of the main body 210. Accordingly, the conventional coating apparatus 200 arranges the plurality of wiper blades 100 in the wiper seating groove H of the pallet 220 as shown in Figure 1c, and then the pallet (through the moving means 220a) 220 is moved by one pitch, and correspondingly, the spray unit 230 forms a coating film by spraying the coating liquid on the first inclined surface 120a of the strip part 120.

Therefore, after the coating film is formed on the first inclined surface 120a, after changing the position of the wiper blade 100 on the pallet 220, the coating liquid is sprayed again to form the coating film on the second inclined surface 120b. Done.

However, the existing coating apparatus 200 on the pallet 220 in changing the position of the wiper blade 100 after forming the coating film on the first inclined surface 120a of the strip portion 120 as described above. Since the second inclined surface 120b of each of the wiper blades 100 arranged must be manually changed so as to be positioned at an upper portion thereof, there is a problem in that a long time is required.

In addition, the coating liquid sprayed by the injection unit 230 in the process of forming the coating film on the first inclined surface 120a of the wiper blade 100 is buried on the upper surface of the pallet 220 in addition to the wiper blade 100. For this reason, before the operation of forming the coating film on the second inclined surface 120b of the wiper blade 100, the coating liquid on the upper surface of the pallet 220 should be dried, and the drying time of the pallet 220 is a working efficiency side. As a result, the loss of work time is a factor that lowers work efficiency.
