[0025] Referring to Figures 1-5 , this utility model provides a coating tooling for preparing a high-performance Lens array film, including:

[0026] A tooling seat 1, on which a plurality of working stations 11 for placing products 6 to be coated are provided. A stop member 12 is provided on the working station 11, and the stop member 12 is arranged between two adjacent working stations 11 for stopping at least one side of the product 6. A limiting member 13 is provided on the working station 11, and the limiting member 13 is used for stopping at least one side of the product 6. A coating port 15 for exposing a channel on a part of the product 6 is opened at the bottom of the working station 11. The stop member 12 and the limiting member 13 can be protrusions respectively formed on the tooling seat 1, and respectively abut against two side walls of the placed product 6, so as to expose the channel on the area to be coated. The product 6 is, for example, a light passing component with 8 lenses arranged side by side on the surface.

[0027] A knife guard 2, which is connected in a strip-shaped groove 14 at the bottom of the tooling seat 1 and corresponds to the coating port 15, and can move along the width direction of the strip-shaped groove 14 for shielding part of the coating port 15 on the product 6. The shape of the knife guard 2 is a strip-shaped knife. The knife guard 2 is placed in the strip-shaped groove 14 at the bottom of the tooling group. In the cavity of the PVD evaporator, the knife guard 2 can be driven manually or by a robotic arm to push the knife guard 2 to move along the strip-shaped groove 14 in the width direction. For the light passing product 6, manually driving the knife guard 2 attached to the bottom of the tooling seat 1 can accurately push the position of the knife guard 2, thereby controlling the exposed area to be coated, and in the cavity of the PVD evaporator, it is convenient to control the formation of a stop edge less than 1 mm to meet the coating size requirements for precision light passing components.

[0028] In one embodiment, a connection hole 3 is provided at the bottom of the tooling seat 1, and strip-shaped holes 4 are provided on the knife guards 2. The knife guards 2 are connected and attached to the bottom of the tooling seat 1 by bolts 5. The strip-shaped holes 4 on the knife guards 2 cooperate with the bolts 5, enabling the knife guards 2 to fit against the bottom of the tooling seat 1 and move along the width direction of the strip-shaped groove 14, so as to precisely control the coating area and the shielding area.

[0029] In one embodiment, the knife guard 2 has a blade and a knife body, and the inclination angle of the blade is 30 - 60 degrees. Through experimental verification, the blade within this inclination angle range can effectively control the width of the edge of the coating area to be less than 1 mm and ensure the effective formation of the coating on the coating area.

[0030] In one embodiment, a shielding boss 21 is provided near the blade at the top of the tool. The top inclination angle of the shielding boss 21 is the same as that of the blade, and the inclined surface of the shielding boss 21 coincides with the inclined surface of the blade. The distance between the top of the shielding boss 21 and the channel of the product 6 is 0.05 mm. The shielding boss 21 can be a boss formed on the top of the tool, and the protruding shielding boss 21 at the top can approach a partial channel to be shielded, reducing the risk of film diffraction and film winding.

[0031] In one embodiment, the width of the strip-shaped groove 14 is greater than the width of the knife guard 2.

[0032] In one embodiment, the coating port 15 extends outward from the top to the bottom of the tooling seat 1 in a flared shape, and the inclination angle is 45 degrees. The peripheral inclination angle of the coating port 15 is 45 - 60 degrees. During coating, the evaporated material can be evenly formed on the coating channel of the light-transmitting component under the guidance of the 60-degree chamfer.
