[0002] Typically, in the manufacturing process of LCD and OLED displays, cleaning equipment such as slit blades is used to clean the displays. A slit blade is a blade structure with fine slits inside. High-pressure fluid is blown out evenly through the blade tip, which can remove foreign objects and impurities from the surface of components such as substrates.

[0003] Currently, common Slit-type blades include liquid cutters, air cutters, and water-air dual-fluid blades. When using these three types of blades, high-pressure fluid can be used to achieve cleaning operations. However, because the slits of the blades are very small, long-term use will cause the blades to become clogged, resulting in a decrease in the cleaning effect of the Slit-type blades on the substrate surface.

[0020] In some embodiments of this application, the cleaning fluid can be one of a liquid, a gas, or a gas-liquid mixture.

[0021] In the above-described scheme of this application, the Slit-type knife includes a knife body 1 and a cleaning component 2. The knife body 1 has a slit groove 3 inside, which penetrates the lower surface of the knife body 1 to form a cutting edge. The slit groove 3 is used to introduce cleaning fluid, which flows out through the cutting edge. The front surface of the knife body 1 has a guide groove 4 extending along the length direction of the knife body 1. The cleaning component 2 includes a sliding guide plate 21, a connecting vertical plate 22, a connecting horizontal plate 23, and a scraper 24 connected in sequence. The sliding guide plate 21 is slidably disposed in the guide groove 4. The scraper 24 passes through the cutting edge and extends into the slit groove 3. The sliding guide plate 21 is perpendicular to the connecting vertical plate 22, the connecting vertical plate 22 is perpendicular to the connecting horizontal plate 23, and the connecting horizontal plate 23 is perpendicular to the scraper 24. The sliding guide plate 21 and the connecting horizontal plate 23 are located on the same side of the connecting vertical plate 22, and the scraper 24 and the connecting vertical plate 22 are located on the same side of the connecting horizontal plate 23. With this structure, the cleaning component 2 can slide along the guide groove 4 to clean the blade edge, preventing the blade edge from becoming clogged after long-term use of the Slit-type blade, thereby improving the cleaning effect of the Slit-type blade on the substrate surface. Furthermore, when the sliding guide plate 21, connecting vertical plate 22, connecting horizontal plate 23, and scraper 24 are connected in sequence, one end of the cleaning component 2 can be fixed by engaging the sliding guide plate 21 with the guide groove 4, and the other end of the cleaning component 2 can be fixed by engaging the scraper 24 with the blade edge. This ensures that the cleaning component 2 can be stably installed on the blade body 1, improving the reliability of the cleaning component 2 installation.

[0022] Understandably, this application improves the stability and uniformity of cleaning by using cleaning component 2 to clean the blade, enhancing the ability to clean the substrate and improving product quality.

[0023] In some embodiments of this application, the cutting groove 3 extends through both the left and right sides of the blade body 1. Two filling blocks are also provided within the cutting groove 3, located on the left and right sides of the blade body 1 respectively. These two filling blocks are used to seal both ends of the cutting groove 3. With this structure, the cutting groove 3 extends through both sides of the blade body 1. By setting two filling blocks to seal both ends of the cutting groove 3, leakage of cleaning fluid from both sides of the blade body 1 can be prevented, ensuring that the fluid flows out evenly and uniformly from the cutting edge, maintaining a stable cleaning effect. Furthermore, it makes the machining of the cutting groove 3 more convenient.

[0024] In some embodiments of this application, a linear drive assembly is mounted on the cutter body 1 and connected to a cleaning assembly 2 to drive the cleaning assembly 2 to slide along the guide groove 4. With this structure, the cleaning assembly 2 can be driven to slide along the guide groove 4 via the linear drive assembly, enabling the cleaning assembly 2 to clean the cutting edge, preventing clogging and improving the overall automation level of the mechanism.

[0025] In some embodiments of this application, the linear drive assembly includes a motor, a lead screw, and a slider. The motor is fixed to the blade body 1. Rotary seats are provided at both ends of the lead screw, which are mounted on the blade body 1. The lead screw is rotatably connected to the rotating seats and is drively connected to the motor. The slider is sleeved on the lead screw and threadedly engaged with it. The slider is connected to the cleaning assembly 2. With this structure, the lead screw can be positioned along the length of the blade body 1. The motor can drive the lead screw to rotate. When the lead screw rotates, it causes the slider to move along the axis of the lead screw. When the slider moves, it causes the cleaning assembly 2 to clean the blade edge along the length of the blade body 1.

[0026] In some embodiments of this application, a plurality of cleaning components 2 are provided in the guide groove 4, and the plurality of cleaning components 2 are arranged sequentially along the length direction of the guide groove 4.
