[0002] While the ring light system used in traditional dicing machines' vision systems provides uniform illumination and enhances image clarity and contrast, since the ring light only provides illumination, any contaminants that land on the workpiece surface or suspended contaminants within the light source assembly can interfere with the accuracy of the vision system during processing, affecting the overall cutting or processing quality. Consequently, to maintain accuracy, operators must frequently perform manual cleaning, which increases workload and reduces production efficiency. Utility Model Content

[0003] (1) Technical problems solved

[0004] In response to the shortcomings of the existing technology, the utility model provides a ring light cleaning device for a dicing machine, which solves the problem that the ring light lighting device used in the existing dicing machine vision system has a single function and pollutants on the workpiece surface and inside the light source easily interfere with the accurate recognition of the vision system.

[0007] A ring light cleaning device for a dicing machine includes a ring light source arranged in the inner cavity of a light source housing, a lens blowing plate detachably mounted on the upper part of the light source housing, an air pipe joint connected to the lens blowing plate, an air flow guide channel arranged between the lens blowing plate and the light source housing, positive pressure gas delivered by the air pipe joint is blown out from the center hole in the middle of the light source housing along the air flow guide channel, forming an air suction effect from top to bottom between the light source housing and the center hole of the lens blowing plate.

[0008] Preferably, the lens air blowing plate is detachably connected to the light source housing via fixing screws, and the fixing screws are evenly distributed on the lens air blowing plate in a circular shape along the axis of the central hole of the lens air blowing plate.

[0009] Preferably, the annular light source is installed in the inner cavity of the light source housing through a heat-conducting gasket and a transparent glass plate, and the wires on the annular light source extend out of the light source housing through a wire outlet hole arranged on the light source housing.

[0013] (3) Beneficial effects

[0014] The utility model has the following beneficial effects:

[0015] The annular light cleaning device of the dicing machine introduces positive pressure airflow from the air connecting pipe joint through the lens air blowing plate and the air connecting pipe joint. Due to the airflow guide channel arranged between the lens air blowing plate and the light source housing, when the airflow enters the guide channel, it will flow along these gaps to the bottom of the light source housing.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 The utility model provides a technical solution: a ring light cleaning device for a dicing machine, comprising a ring light source 6 arranged in the inner cavity of a light source housing 4, a lens blowing plate 1 detachably mounted on the upper part of the light source housing 4, an air pipe joint 2 connected to the lens blowing plate 1, an air flow guide channel arranged between the lens blowing plate and the light source housing 4, the positive pressure gas delivered by the air pipe joint 2 is blown out from the central hole in the middle of the light source housing 4 along the air flow guide channel, forming an air suction effect from top to bottom between the light source housing 4 and the central hole of the lens blowing plate 1.

[0022] The utility model provides a lens air blowing plate 1 and an air pipe joint 2, and introduces a positive pressure airflow from the air pipe joint 2. Due to the airflow guide channel arranged between the lens air blowing plate 1 and the light source housing 4, when the airflow enters the guide channel, it will flow along these gaps to the bottom of the light source housing 4. The airflow at the bottom of the light source housing 4 will be faster and have a lower pressure than the air flow above, and a downward suction effect will be formed in the center hole of the light source housing 4, which will extract the dust and water mist in the center hole, and at the same time, it can blow away the water mist or other pollutants on the surface of the workpiece of the working disk below the light source housing 4, so as to ensure the accuracy of the recognition of the entire visual system.

[0023] Reference Figure 3 As shown, in this embodiment, the lens air blowing plate 1 is detachably connected to the light source housing 4 via fixing screws 3. The fixing screws 3 are evenly distributed in a circular pattern along the axis of the central hole of the lens air blowing plate 1. The detachable installation of the lens air blowing plate 1 and the light source housing 4 facilitates the disassembly and maintenance of the entire cleaning device during daily use.

[0024] Reference Figure 2 and 3 As shown, in this embodiment, the annular light source 6 is mounted within the inner cavity of the light source housing 4 through a light-transmitting glass plate with the aid of a thermally conductive gasket 8. The wires 7 of the annular light source 6 extend out of the light source housing 4 through a wire outlet 5 provided in the light source housing 4. The wire outlet 5 facilitates wire routing from the annular light source 6, and the thermally conductive gasket 8 facilitates heat conduction and dissipation from the annular light source 6.

[0025] Reference Figure 2 and 3As shown, in this embodiment, one side of the thermally conductive gasket 8 is fully bonded to the ring light source 6. The thermally conductive gasket 8 is made of a thermally conductive soft silicone gasket, and the light-transmitting glass plate 9 is a light-transmitting tempered glass plate. The thermally conductive soft silicone gasket primarily provides cushioning, absorbing shock and vibration. It also has excellent thermal conductivity, helping to dissipate heat and protect the optical components within the ring light source 6. The light-transmitting tempered glass plate primarily protects the internal optical components from dust and contamination. Tempered glass has a high light transmittance, ensuring loss-free light transmission. Dust-proof tempered glass can also be used.

[0026] Reference Figure 2 As shown, in this embodiment, the airflow guide channel includes a connecting channel 10 arranged on the lens air blowing plate 1 and an air blowing groove 11 arranged in the middle of the light source housing 4. The connecting channel 10 is connected to the air pipe joint 2, and the air blowing groove 11 is connected to the center hole of the light source housing 4. The positive pressure airflow introduced from the air pipe joint 2 is sent into the connecting channel 10 and blown out from the air blowing groove 11 along the center hole of the light source housing 4. Therefore, the airflow at the bottom of the light source housing 4 will be faster and less pressured than the air flow at the top, which will form a downward suction effect in the center hole of the light source housing 4 and the lens air blowing plate, extracting dust and water mist in the center hole, and at the same time blowing away water mist or other contaminants on the surface of the workpiece on the working disk below the light source housing 4.

[0027] Reference Figure 2 and 3 As shown, in this embodiment, the upper portion of the lens air-blowing plate 1 is mounted on the lens of the visual system via a socket hole 12. A sealing ring 13 is disposed between the cavity wall of the socket hole 12 and the outer surface of the lens. The provision of sealing ring 13 ensures airtightness at the connection between the lens air-blowing plate 1 and the lens. This effective sealing measure prevents air leakage at the connection, thereby ensuring stable operation of the entire cleaning system.
