Description

Technical Field

[0001] The utility model relates to the technical field of light sources, in particular to a linear light source and a detection device. Background Art

[0002] Current line light sources consist of a focusing rod and multiple linearly arranged light beads. The light from these multiple light beads converges through the focusing rod into a linear spot, illuminating the workpiece. Because the light convergence point is fixed, the distance between the line light source and the workpiece is also fixed. Changes in workpiece size require readjusting the height of the line light source to accommodate actual use. This requires pausing the equipment during readjustment, which reduces inspection efficiency.

[0003] In view of this, it is necessary to design a line light source and a detection device that can detect workpieces of two different thicknesses without adjusting the height position of the line light source.

[0047] Example 1

[0048] In light of the aforementioned shortcomings of existing linear light sources, the applicant, drawing on years of extensive practical experience and expertise in the design and manufacture of such products, combined with applied theory, has actively engaged in research and innovation, hoping to develop a technology that can address these shortcomings and make linear light sources more practical. Through continuous research and design, repeated prototype production, and refinement, the applicant has finally developed the present utility model, which possesses proven practical value.

[0049] Please refer to Figures 1 to 6The embodiment of the utility model provides a linear light source, comprising a focusing rod 1, a first lamp group, and a second lamp group. The first lamp group comprises a plurality of first lamp beads 2, the arrangement direction of the plurality of first lamp beads 2 is parallel to the center line of the focusing rod 1, and the first lamp beads 2 emit light toward the focusing rod 1; the second lamp group comprises a plurality of second lamp beads 3, the arrangement direction of the plurality of second lamp beads 3 is parallel to the center line of the focusing rod 1, and the second lamp beads 3 emit light toward the focusing rod 1; a second lamp bead 3 is arranged between two adjacent first lamp beads 2, and the distance from the second lamp bead 3 to the focusing rod 1 is greater than the distance from the first lamp bead 2 to the focusing rod 1; the first lamp group and the second lamp group can be turned on or off separately. The fact that the first lamp group and the second lamp group can be turned on or off separately means that the first lamp group can be turned on or off separately, and the second lamp group can also be turned on or off separately.

[0050] In actual application, only the first light group or the second light group can be turned on separately to make the position of the light-collecting point of the focusing rod 1 different to meet the detection needs of workpieces with different thicknesses.

[0051] Preferably, the first and second light groups are located on the same side of the focusing rod 1 so that light can be emitted from the same light outlet. Of course, the first light group can be located on the upper left of the focusing rod 1 and the second light group can be located on the upper right of the focusing rod 1. In this case, two light outlets are required.

[0052] Optionally, the line light source in this embodiment further includes a housing 4 having a mounting groove 41 formed therein. The first and second lamp groups are both located within the mounting groove 41, and the focusing rod 1 is clamped by the opposing walls of the mounting groove 41. The housing 4 supports the first and second lamp groups, as well as the focusing rod 1, and the opposing walls of the mounting groove 41 securely clamp the focusing rod 1, preventing it from shaking.

[0053] Optionally, at least three mounting protrusions 42 are spaced apart on the bottom wall of the mounting groove 41, and a first lamp bead 2 is mounted on the top of each mounting protrusion 42; a mounting groove 401 is formed between two adjacent mounting protrusions 42, and a second lamp bead 3 is mounted in the mounting groove 401. The arrangement of the mounting protrusions 42 creates a height difference between the first lamp bead 2 and the second lamp bead 3, so that the light emitted by the first lamp group and the light emitted by the second lamp group have different light convergence points, such as Figure 2 and Figure 3 As shown, the light convergence point is the intersection of two dotted lines. Generally speaking, the light convergence point is projected onto the surface of the workpiece to form a line spot.

[0054] Optionally, the second lamp group further includes a second circuit board 31 , and the second lamp beads 3 are mounted on the second circuit board 31 .

[0055] Alternatively, as Figure 3The bottom of the mounting groove 401 is tilted, and a triangular slider 5 is slidably mounted within the mounting groove 401. The second lamp bead 3 is mounted on one side of the top of the triangular slider 5, and the top surface of the triangular slider 5 supports the second circuit board 31. The two ends of the second circuit board 31 slide in contact with the side walls of the mounting groove 41. The triangular slider 5 can be adjusted to adjust the length of its insertion into the mounting groove 401 to adjust the height of the second lamp bead 3, and one end of the triangular slider 5 extends beyond the housing 4. Specifically, when the triangular slider 5 moves to the left, it causes the second circuit board 31 to slide downward, bringing the second lamp bead 3 closer to the focusing rod 1. Therefore, the triangular slider 5 can be used to adjust the location of the light source's focal point after the light emitted by the second lamp bead 3 is focused by the focusing rod 1, thereby significantly expanding the applicability of the linear light source.

[0056] Optionally, the linear light source further includes an electric adjustment device for adjusting the height of the second lamp assembly; the electric adjustment device includes a support plate mounted on the electric telescopic device and the telescopic shaft of the electric telescopic device, and the support plate extends into the mounting slot 401 to support the second lamp bead 3. In this embodiment, the position of the second lamp bead 3 is adjusted using the electric adjustment device, making adjustment simpler and more convenient for the operator.

[0057] Optionally, the distance between the second lamp bead 3 and the focusing rod 1 is adjustable, thereby increasing the applicable range of the line light source.

[0058] Optionally, the first lamp group further includes a first circuit board 21 , and the first lamp beads 2 are mounted on the first circuit board 21 .

[0059] Optionally, the first lamp bead 2 and the second lamp bead 3 are both LED lamps.

[0062] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
