Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of visual recognition of dicing machines, and specifically to a visual device for a double-lens dicing machine. Background Art
[0002] The visual module of a dicing machine is a key component for achieving precise image processing and automatic alignment. The design of a single-lens in the traditional visual module of a dicing machine cannot switch magnifications, which limits the flexibility and adaptability of operations. Due to the fixed magnification, it is difficult for a single-lens visual module to simultaneously take into account global observation and detail processing, easily leading to operation errors and affecting processing accuracy. In addition, the inability to switch magnifications also means that when processing workpieces of different sizes or shapes, it is necessary to frequently adjust the lens or replace the equipment, increasing the complexity of operations and the time cost. Therefore, when facing diverse processing requirements, the traditional visual module of a dicing machine often appears powerless and cannot meet the requirements of modern precision processing. At the same time, the entire lighting system supporting visual recognition has a relatively single function, making it difficult to ensure the clarity and richness of details of the images captured by the visual system, reducing the efficiency and accuracy of processing or detection.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figure 1 , the present utility model provides a technical solution: a double-lens 10 dicing machine vision device, including two cameras 11 and lenses 10 that are matched with the cameras 11 one by one. The two lenses 10 are connected through a reflection component 6, and the two lenses 10 cooperate with the reflection component 6 to play a role of high-magnification amplification. An annular light component 9 is arranged at one end of one of the lenses 10, and a point light source 14 for providing illumination for the lens 10 is arranged on one side of one of the lenses 10. A vision air blowing pipe 7 is arranged outside the annular light component 9 perpendicular to the X-axis and Y-axis to blow air onto the surface of the workpiece and the cutting track.
[0024] The present utility model, through the design of the dual-lens 10 vision device, aims to flexibly adapt to different observation requirements through the convenient switching between high and low magnifications. At the same time, sharing a point light source 14 and a ring light not only simplifies the lighting system, reduces the cost and maintenance work of the device, but also ensures the consistency of image brightness and contrast at different magnifications. In addition, the combination of the point light source 14 and the ring light realizes the compactness of the structure, effectively guarantees the effective working distance, and provides stable and reliable lighting support for precision operations. Through the vision air blow pipes 7 arranged on the X-axis and Y-axis, by blowing air, the water mist or other impurities left on the workpiece surface and the cutting path during work can be effectively cleaned, ensuring better focusing of the vision system, clear images analyzed during shooting, and improving the recognition accuracy.
[0025] Refer to Figure 1 and 3 As shown, in this embodiment, the camera 11 and the lens 10 are fixedly arranged on the vision rear cover 4 through a dual-vision mounting plate 5. A protective shell 16 is arranged outside the camera 11 and the lens 10 on one side of the vision rear cover 4. A vision air blow joint 8 is fixedly arranged on the protective shell 16. The vision air blow pipe 7 is connected in communication with the air outlet end of the vision air blow joint 8. By externally connecting a blowing device to the vision air blow joint 8, the vision air blow pipes 7 arranged on the X-axis and Y-axis can blow air. By blowing air, the water mist or other impurities left on the workpiece surface and the cutting path during work can be effectively cleaned, ensuring better focusing of the vision system, clear images analyzed during shooting, and improving the recognition accuracy.
[0026] Refer to Figure 2 and 4 As shown, in this embodiment, a linear drive module 1 is fixedly arranged on the lower cavity wall of the vision rear cover 4. The movable end of the linear drive module 1 is fixedly connected to the microscope dust-proof plate 2. The microscope dust-proof plate 2 linearly moves under the drive of the linear drive module 1 to cover the lower end face of the ring light assembly 9. The movable end of the linear drive module 1 and the microscope dust-proof plate 2 are fixed on both sides through nuts, enabling the linear drive module 1 to push out or retract the microscope dust-proof plate 2. When the linear drive module 1 is pushed out, the microscope dust-proof plate 2 covers the lower end face of the ring light assembly 9, effectively preventing dust from disturbing the lens 10; when retracted, it drives the microscope dust-proof plate 2 to retract, ensuring the cleanliness of the lens 10 and also ensuring the normal and effective operation of the vision module. In the actual application process, the linear drive module 1 can adopt a linear module, a linear motor, or a cylinder, etc. The linear drive module 1 is a cylinder, seemingly only able to connect to air.
[0027] Refer to Figure 4As shown, in this embodiment, a dust-proof guide plate 3 is fixedly arranged on the lower cavity wall of the visual rear cover 4, and the microscope dust-proof plate 2 is slidably connected to the dust-proof guide plate 3 through the arranged notches. By arranging the dust-proof guide plate 3, the smooth operation of the microscope dust-proof plate 2 can be ensured.
[0028] Refer to Figure 5 As shown, in this embodiment, the annular light component 9 is sleeved and arranged at the lower end of a lens 10. The annular light component 9 includes an annular lamp head 93 and a connecting sleeve 91 fixedly connected to the annular lamp head 93. The connecting sleeve 91 is sleeved on the lens 10, and a sealing ring 92 is arranged between the connecting sleeve 91 and the lens 10. A light-transmitting plate 94 with a central opening is fixedly arranged on the lower end surface of the annular lamp head 93. By arranging the annular lamp head 93, the annular light directly irradiates the working area. The uniform light formed by it can effectively eliminate shadows and highlight the edge features of the workpiece, which is crucial for operations such as precise alignment and dimensional measurement. Through the organic combination of these two light sources, not only the overall performance of the visual system is optimized, but also the efficiency and accuracy of processing or detection are significantly improved. Optimize the performance of the visual system and improve the operation efficiency and accuracy. By arranging the sealing ring 92, the sealing performance between the lens 10 and the connecting sleeve 91 can be effectively ensured, preventing dust or water vapor from escaping into the inner cavity of the connecting sleeve 91 through the gap during daily operation and affecting the accuracy of subsequent visual recognition.
[0029] Refer to Figure 5 As shown, in this embodiment, a blowing nozzle 95 is arranged outside the connecting sleeve 91. A gas channel 96 communicating with the blowing nozzle 95 is arranged between the connecting sleeve 91 and the annular lamp head 93, and a gap communicating with the gas channel 96 is arranged between the lower end of the connecting sleeve 91 and the annular lamp head 93. The airflow blown out from the blowing nozzle 95 can be blown out from the gas channel 96 and the gap between the connecting sleeve 91 and the annular light joint. The blowing function can be used to clean the water mist or other impurities on the workpiece working plate below the annular light component 9; a light-transmitting component is arranged at the bottom of the annular lamp head 93, usually made of tempered glass, mainly to protect the internal optical elements from dust and pollution. At the same time, the tempered glass has a high light transmittance to ensure no loss of light transmission.
