Technical Field

[0002] A line scan light source is a light source that forms a linear light spot, which is projected onto the surface of a workpiece to facilitate camera inspection of surface defects. Existing line scan light sources typically involve directly attaching the lamp panel to the housing, with heat sink fins mounted on the housing to cool the lamp panel. However, this method of cooling the lamp panel has low efficiency and is insufficient to meet the light output requirements of high-power lamp panels.

[0003] Therefore, it is necessary to design a line scan light source that can improve the cooling efficiency of the lamp panel.

[0004] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0043] Please refer to Figures 1 to 2 This utility model embodiment provides a line scan light source, including a heat-conducting plate 1, a strip lamp plate 2, and a semiconductor cooling plate 3.

[0044] The strip light panel 2 is fixedly connected to the heat-conducting plate 1; one side of the semiconductor cooling plate 3 is attached to the heat-conducting plate 1, and the other side is attached to the strip light panel 2, with the strip light panel 2 emitting light to the side away from the semiconductor cooling plate 3.

[0045] In this embodiment, the heat-absorbing side of the semiconductor cooling plate 3 is attached to the strip light panel 2 to absorb the heat emitted by the strip light panel 2; the heat-dissipating side of the semiconductor cooling plate 3 is attached to the heat-conducting plate 1 to transfer heat to the heat-conducting plate 1, and the heat-conducting plate 1 dissipates the high-temperature heat to the outside. Preferably, the heat-conducting plate 1 is a copper plate, as copper plates have better thermal conductivity.

[0046] In this embodiment, even if the temperature of the heat-conducting plate 1 is higher than that of the strip light panel 2, it can still maintain a good heat dissipation effect on the strip light panel 2. Existing methods that directly use heat dissipation fins cannot achieve the above effect.

[0047] The line scan light source in this embodiment has good heat dissipation effect, which can keep the strip light panel 2 within a reasonable temperature range. Compared with the line scan light source in the prior art, it significantly improves the cooling efficiency of the strip light panel 2.

[0048] Optionally, the line scan light source also includes a heat sink fin assembly 4 and a cooling fan 5. The heat sink fin assembly 4 is attached to the side of the heat conduction plate 1 away from the semiconductor cooling plate 3. The heat sink fin assembly 4 includes a plurality of heat sink fins 41 spaced apart. The cooling fan 5 is installed on the top of the heat sink fin assembly 4 away from the heat conduction plate 1, and the cooling fan 5 is used to blow cooling gas into the heat dissipation gaps between the heat sink fins 41.

[0049] Specifically, the heat from the heat-conducting plate 1 is transferred to the heat dissipation fins 41, and then the heat in the heat dissipation fins 41 is quickly dissipated to the outside under the cooling of the cooling fan 5.

[0050] Optionally, such as Figure 3 The heat-conducting plate 1 is connected to a heat-conducting copper pipe 11, which passes through the heat dissipation fin assembly 4. The heat-conducting copper pipe 11 can further improve the efficiency of heat transfer to the heat dissipation fin assembly 4, enabling the heat dissipation fin assembly 4 to cool the heat-conducting plate 1 more efficiently.

[0051] Optionally, the line scan light source also includes several temperature detectors; several semiconductor cooling plates 3 are spaced apart, and each area of ​​the strip light panel 2 cooled by a semiconductor cooling plate 3 is equipped with a temperature detector, and the temperature detector is electrically connected to the corresponding semiconductor cooling plate 3. Specifically, the temperature detector detects the temperature of the corresponding area. If the temperature of the corresponding area is too high, the cooling efficiency of the corresponding semiconductor cooling plate 3 is increased, thereby maintaining the strip light panel 2 within a reasonable temperature range.

[0052] Optionally, the heat dissipation fins 41 are perpendicular to the heat conduction plate 1; at least four cooling fans 5 are spaced apart, and the air outlet direction of the cooling fans 5 is parallel to the heat dissipation fins 41.

[0053] Optionally, the line scan light source also includes a focusing rod 6 mounted on the light-emitting side of the strip light panel 2; the focusing rod 6 is parallel to the strip light panel 2, and the cross-section of the focusing rod 6 is circular. The light emitted from the strip light panel 2 is focused by the focusing rod 6 to form a linear light spot on the workpiece surface. It should also be noted that the line scan light source also includes a housing, in which the focusing rod 6 and the strip light panel 2 are both mounted.

[0054] Optionally, the focusing rod 6 is a glass rod.

[0055] Optionally, such as Figure 4 The heat dissipation fins 41 are curved in a serpentine shape away from the heat conduction plate 1, and adjacent heat dissipation fins 41 are parallel to each other. Specifically, this can effectively increase the heat dissipation area, and together with the airflow from the cooling fan 5, it can effectively improve the heat dissipation effect.

[0056] Optionally, the strip light board 2 includes a strip circuit board and LED beads arranged at intervals along the central direction of the strip circuit board.

[0057] Optionally, each semiconductor cooling plate 3 is individually connected to a set of control modules.

[0058] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
