After continuous research and design, and repeated trial production and improvement, the present utility model with real practical value was finally created.

[0046] Please refer to Figure 1 to Figure 2 The embodiment of the utility model provides a light source device, which can adjust the light output direction without adjusting the top plate 1.

[0047] The light source device includes: a top plate 1, a lamp board is installed at the bottom of the top plate 1; a side plate 2, connected to the top plate 1; a diffusion plate 3, installed on the light-emitting side of the top plate 1, and can be rotated around a first rotation center line to adjust the tilt angle, the first rotation center line is parallel to the bottom surface of the top plate 1; the side surface of the side plate 2 close to the diffusion plate 3 is a total reflection surface 201, which is used to reflect the light emitted by the lamp board to the diffusion plate 3.

[0048] In this embodiment, the diffuser plate 3 rotates relative to the light board, and the light passes through the diffuser plate 3 at different tilt angles, thereby changing the angle of the final diffused light emission direction, that is, changing the emission direction of the diffused light.

[0049] In this embodiment, the purpose of adjusting the light emitting direction can be achieved by simply adjusting the rotation angle of the diffuser plate 3 around the first rotation center line. It should also be noted that the light source device in this embodiment has a relatively small adjustment range of the light emitting direction. If the rotation angle of the diffuser plate 3 is too large, the light of the lamp board may be directly emitted to the workpiece 100 without passing through the diffuser plate 3.

[0050] It should also be noted that the first rotation center line is located at the bottom side of the light board and is perpendicular to the side board 2, so that the diffuser 3 can prevent the light from directly hitting the workpiece 100. Figure 2 Preferably, the diffuser plate 3 can be set to be longer.

[0051] Optionally, the side panel 2 is rotatably connected to the top panel 1, and the side panel 2 can rotate around a second rotation center line to adjust the tilt angle; the side panel 2 is provided with a rotation groove 21, and the edge of the top panel 1 is provided with a rotation shaft 11, and the rotation shaft 11 can be rotatably installed in the rotation groove 21; the center line of the rotation shaft 11 is the second rotation center line, and the first rotation center line is parallel to the second rotation center line.

[0053] Optionally, the light source device also includes an end sealing plate 4; the top plate 1 is fixedly connected to the end sealing plate 4, and the opposite ends of the top plate 1 are connected to the end sealing plates 4, and the two end sealing plates 4 are parallel to each other; the side plate 2 is installed between the two end sealing plates 4, and the opposite end surfaces of the side plate 2 can be slidably fitted with the two end sealing plates 4 respectively.

[0054] It should be noted that the end sealing plate 4 can well support the diffuser plate 3. The opposite end surfaces of the side plate 2 are respectively slidably fitted with the two end sealing plates 4, which can avoid light leakage and does not affect the rotation adjustment of the side plate 2.

[0055] Optionally, the light source device further comprises a rotation hole 401 formed on the end sealing plate 4, and the diffusion plate 3 is provided with a rotation column extending into the rotation hole 401, the rotation column is rotatably connected to the rotation hole 401, and the center line of the rotation hole 401 coincides with the first rotation center line. The rotational cooperation between the rotation column and the rotation hole 401 can achieve the purpose of enabling the diffusion plate 3 to rotate around the first rotation center line.

[0056] Optionally, an arc groove 402 is provided on the end sealing plate 4 around the first rotation center line, and a connection fixing portion extending into the arc groove 402 is provided on the diffuser plate 3, and the fastening screw is connected to the connection fixing portion to fix the diffuser plate 3, that is, the diffuser plate 3 is fixed to the end sealing plate 4. Specifically, the fastening screw is screwed on the connection fixing portion, thereby fixing the connection fixing portion at the current position. At this time, the connection fixing portion and the end sealing plate 4 are relatively fixed, and the purpose of fixing the diffuser plate 3 is achieved. When the inclination angle of the diffuser plate 3 needs to be adjusted, the fastening screw is loosened, and then the position of the connection fixing portion is adjusted by sliding along the arc groove 402, and finally the fastening screw is screwed.

[0057] Optionally, the top plate 1 is provided with an observation port 101 for the camera 200 to take photos of the inspection workpiece 100; two diffuser plates 3 are provided, and the two diffuser plates 3 are symmetrically arranged about the center line of the observation port 101; two side plates 2 are provided, and the two side plates 2 are symmetrically arranged about the observation port 101. The two diffuser plates 3 rotate around the corresponding first rotation center line respectively.

One of the diffusion plates 3 scatters the light of the first light-emitting component 51, and the other diffusion plate 3 scatters the light of the second light-emitting component 52.

[0059] Optionally, a slope structure 22 is provided on one side of the side plate 2 close to the diffuser plate 3, and the slope surface of the slope structure 22 is a total reflection surface 201. Specifically, the slope structure 22 is provided so that the total reflection surface 201 can better reflect light to the diffuser plate 3, and then the diffuser plate 3 emits the diffused light to the workpiece.
