[0050] Embodiment 1

[0051] In view of the defects existing in the above-mentioned existing light source devices, based on the rich practical experience and professional knowledge in the design and manufacture of such products for many years by the applicant, and in cooperation with the application of theory, active research and innovation have been carried out in the hope of creating a technology that can solve the defects in the prior art and make the light source device more practical. After continuous research, design, and repeated sample making and improvement, the present utility model with practical value has finally been created.

[0052] Please refer to Figures 1 to 4 , an embodiment of the present utility model provides an adjustable linear light source device, including: a condenser rod 1, which has a light condensing effect and finally forms a linear light spot to be projected on the surface of the workpiece; a rotatable support 2, parallel to the condenser rod 1, and the condenser rod 1 and the rotatable support 2 are arranged at intervals; a linear light emitting component 3, installed on the outer peripheral surface of the rotatable support 2 close to the condenser rod 1 and parallel to the condenser rod 1; the rotatable support 2 is used to support and adjust the position of the linear light emitting component 3 and keep the linear light emitting component 3 parallel to the condenser rod 1; a rotation driving device 4, used to drive the rotatable support 2 to rotate around the center line of the rotatable support 2.

[0053] In this embodiment, the condenser rod 1 and the linear light emitting component 3 are kept parallel, and the light emitted by the linear light emitting component 3 forms a linear light spot (i.e., the focal line) after being condensed by the condenser rod 1. When it is necessary to change the light emitting direction of the adjustable linear light source device, the rotation driving device 4 drives the rotatable support 2 to rotate around the center line of the rotatable support 2, so as to achieve the effect of the light emitting direction being to the left as shown in Figure 3 or the effect of the light emitting direction being to the right as shown in Figure 4 . It should also be supplemented that the linear light emitting component 3 is a scattering light source so that the linear light emitting component 3 can still emit light towards the condenser rod 1 after rotation. It should also be noted that the rotation driving device 4 drives the rotatable support 2 to rotate around the center line of the rotatable support 2, changing the position of the focal line, enabling the adjustable linear light source device to illuminate workpieces at different distances and better adapting to different detection environments.

[0054] It should be particularly supplemented that the adjustable linear light source device further includes a housing, the housing surrounds the condenser rod 1, the rotatable support 2, the linear light emitting component 3 and the condenser rod 1, and the housing is formed with a light outlet for light emission.

[0055] Optionally, the rotatable support 2 is in a cylindrical shape, and the linear light emitting component 3 is installed on the outer cylindrical surface of the rotatable support 2. The cylindrical rotatable support 2 can make it easier to install the linear light emitting component 3 on the outer wall surface of the rotatable support 2.

[0056] Optionally, the rotation driving device 4 includes a driving motor 41 and a rotating plate 42; the rotating plate 42 is fixedly connected to the rotating shaft of the driving motor 41, and the rotating plate 42 is fixedly connected to the rotatable support 2. That is, the driving motor 41 drives the rotating plate 42 to rotate, and the rotation of the rotating plate 42 drives the rotatable support 2 to rotate around the center line of the rotatable support 2.

[0057] Optionally, the linear light-emitting component 3 includes a strip-shaped circuit board 31 and a row of lamp beads 32 mounted on the strip-shaped circuit board 31; the strip-shaped circuit board 31 is parallel to the center line of the light condensing rod 1, and the arrangement direction of the lamp beads 32 is parallel to the center line of the light condensing rod 1; the strip-shaped circuit board 31 is mounted on the rotatable support 2. The strip-shaped circuit board 31 is used to supply power to the lamp beads 32 and control the opening and closing of the lamp beads 32.

[0058] Optionally, the linear light-emitting component 3 further includes an orientation adjustment device 33 for adjusting the orientation direction of the strip-shaped circuit board 31; the strip-shaped circuit board 31 is rotatably connected to the rotatable support 2, and the orientation adjustment device 33 includes a telescopic device 331 hinged to the rotatable support 2 and a visual detection device 332 for detecting the position of the light condensing rod 1, and the telescopic device 331 is electrically connected to the visual detection device 332; the body of the telescopic device 331 is installed in the rotatable support 2, and the telescopic shaft of the telescopic device 331 passes through the rotatable support 2 and is hinged to the strip-shaped circuit board 31; the telescopic device 331 adjusts the orientation direction of the lamp beads 32 on the strip-shaped circuit board 31 by controlling the telescopic length of the telescopic shaft. Preferably, the linear light-emitting component 3 includes a carrier plate, the linear light-emitting component 3 is mounted on the carrier plate, and then the carrier plate is connected with a rotating shaft, and the carrier plate is rotatably connected to the rotatable support 2 through the rotating shaft, and the telescopic shaft of the telescopic device 331 is hinged to the carrier plate.

[0059] Specifically, after the rotatable support 2 rotates by a certain angle, if the orientation angle of the strip-shaped circuit board 31 is not adjusted, then as the rotation angle increases, less and less light is irradiated on the light condensing rod 1, resulting in weaker light output, and it may not be possible to meet the requirement of illuminating the workpiece. Therefore, the telescopic device 331 is provided to adjust the orientation direction of the strip-shaped circuit board 31 so that the lamp beads 32 are directly facing the light condensing rod 1, so that the rotated linear light-emitting component 3 can also well emit light to the light condensing plate 1, and can better ensure the lighting effect on the workpiece. That is, after the linear light-emitting component 3 rotates and adjusts its position, it can also better ensure the lighting effect of the adjustable linear light source device on the workpiece and avoid the problem of a large decrease in lighting brightness.

[0060] Optionally, a plurality of linear light-emitting components 3 are arranged in a circumferential array on the outer periphery of the rotatable support 2, and the colors of the light rays emitted by two adjacent linear light-emitting components 3 are different. Specifically, in the adjustable linear light source device of this embodiment, the rotatable support 2 can be directly rotated to make the lamp beads corresponding to the light output color face the condenser rod 1, so as to achieve the purpose of switching the light output color. In the adjustable linear light source device of this embodiment, it is convenient to switch the light output color, which can meet the needs of different color light irradiation, and further expands the scope of application. The light rays emitted by the linear light-emitting component 3 can be white light, red light, green light, blue light, yellow light or other color lights.

[0061] Optionally, as Figure 5 and Figure 6 , the adjustable linear light source device further includes a support plate 401 and a translation pushing device 5; the translation pushing device 5 is connected to the condenser rod 1, and includes a pushing part for pushing the condenser rod 1 to translate horizontally and a translation driving part for driving the driving part to move horizontally. Specifically, when pushing the condenser rod 1 to translate left and right, the light output direction and the position of the condenser focal line can also be adjusted, which can further improve the scope of application of the adjustable linear light source device and change the light output direction and light output irradiation effect of the adjustable linear light source device. The horizontal position of the condenser rod 1 is adjustable, which is combined with the adjustable rotation angle of the rotatable support 2. Together with the multi-group different-color linear light-emitting components 3 arranged on the rotatable support 2, the light output effect is effectively broadened, and the light output direction, the light focus point and the light output color can all be adjusted.

[0062] Optionally, the adjustable linear light source device further includes a support plate 401, and a sliding groove 402 is arranged on the support plate 401. One end of the condenser rod 1 is slidably installed in the sliding groove 402, so that the installation stability of the condenser rod 1 is better.

[0063] Optionally, as Figure 7 , the adjustable linear light source device further includes an angle adjustment device 6 for driving the rotatable support 2 to rotate around the center line of the condenser rod 1; the angle adjustment device 6 includes a sector plate 61 fixedly connected to the condenser rod 1, and an arc-shaped sliding groove 601 is arranged on the sector plate 61 around the center line of the condenser rod 1. The rotatable support 2 is slidably connected to the arc-shaped sliding groove 601; the angle adjustment device 6 further includes a driving component 62 for pushing the rotatable support 2 to slide along the arc-shaped sliding groove 601. Specifically, in this embodiment, the rotatable support 2 can be pushed to slide along the arc-shaped sliding groove 601, and combined with the self-rotation of the rotatable support 2, the relative position between the linear light-emitting component 3 and the condenser rod 1 can be better adjusted, providing more different lighting effects.
