Description

Technical Field

[0001] This utility model relates to the field of filter processing equipment, and in particular to an automated filter printing mechanism. Background Technology

[0002] A filter is an optical device that selectively transmits radiation in a specific wavelength range through absorption or interference effects.

[0003] The existing printing process has the following problems: 1. Traditional filter printing relies on manual adjustment, which is prone to registration errors and affects the optical performance of the filter; 2. Poor ink thickness uniformity leads to fluctuations in transmittance; 3. The lack of high-precision automatic alignment leads to a decrease in filter printing efficiency.

[0004] For example, Chinese patent CN202520635974.0 uses a conveyor belt to print filters. However, this mechanism has poor support during printing, which affects the thickness of the ink and thus the stability of the printing. Using a single feeding method results in low efficiency. Utility Model Content

[0005] The main purpose of this invention is to propose an automated filter printing mechanism, which aims to improve existing printing mechanisms and achieve both precision printing and high-efficiency loading and unloading.

[0006] To achieve the above objectives, this utility model proposes an automated filter printing mechanism, comprising: A base, wherein a turntable is rotatably mounted in the middle of the base, and the turntable is provided with a plurality of slots distributed circumferentially along the axis, the slots being used to place filters; A substrate, wherein the substrate is moved vertically by a lifting device; A printing apparatus, the printing apparatus comprising a screen printing plate disposed on a substrate and a coating device disposed above the screen printing plate; The coating device is mounted on the horizontal moving device; The first driving device is used to drive the turntable to rotate and move the filter to be processed to a position below the screen printing plate. The lifting device is used to move the screen printing plate between a position close to the filter and a position far away from the filter; The horizontal moving device is used to drive the coating device to move back and forth (and to coat the filter ink onto the filter).

[0007] In practical design, automated adjustment at multiple positions reduces manual debugging. An automated mechanism places the fixture in the slot, and a first drive unit rotates it to a position below the screen printing plate. A lifting device then lowers the printing unit, bringing the screen printing plate into contact with the filter. A horizontal moving device then drives the coating device to reciprocate, achieving ink coating. In practical design, a visual inspection device detects the ink height, and the lowering stroke of the lifting device is adjusted to regulate the bonding gap. The number of coating passes on the screen printing plate also adjusts the ink thickness; one coat equals one layer of ink.

[0008] Specifically, high-precision alignment system: 1. The visual CCD identifies the reference marks of the slot on the fixture and the product, thereby ensuring the stability of the adjustment; 2. A multi-degree-of-freedom fine-tuning platform to compensate for substrate deformation errors, namely, the lifting device is equipped with a servo telescopic motor to adjust the bonding gap, and a fine-tuning screw can also be set. 3. The constant pressure scraper system (pneumatic servo control) ensures stable reciprocating movement. 2.2 Nanoscale porous ceramic mesh can reduce ink diffusion. 3. Conveying Module: A rotary servo motor is used for conveying, enabling precise positioning of the filter. Attached Figure Description
