[0002] In vision detection, a vision detection device uses an industrial camera to photograph an object to be detected and converts the object to be detected from an image signal into a digital signal. During the photographing process, a light source is required to illuminate the object to be detected to achieve a better photographing effect.

[0003] In order to avoid illumination dead angles, different objects to be detected have different requirements for the illumination range. When different objects to be detected need to be detected on a vision detection line, it is impossible to quickly adjust the illumination range.

[0024] First embodiment:

[0025] Figure 1 The structural schematic diagram of the adjustable light source mechanism for visual inspection in the first embodiment of the present utility model is shown. Figure 2 The side view structural diagram of the telescopic structure in the first embodiment of the present utility model is shown. In combination with Figure 1 and Figure 2 as shown, the present utility model discloses an adjustable light source mechanism for visual inspection.

[0026] The adjustable light source mechanism for visual inspection includes: a main body 1, a guiding bracket 3 arranged in the main body 1, a telescopic structure 4 movably connected to the guiding bracket 3, a moving member 6 movably connected to one end of the telescopic structure 4, and a light source 5 distributed along the main body 1.

[0027] Wherein, the light source 5 is connected to the telescopic structure 4. Exemplarily, the guide bracket 3 is a curved structure. The upper and lower ends of the telescopic structure 4 can expand or contract in the up and down directions. The middle position of the telescopic structure 4 is movably connected to the guide bracket 3. The moving member 6 moves along the guide bracket 3 away from the middle position of the telescopic structure 4, and the moving member 6 pulls one end of the telescopic structure 4 to expand, and the telescopic structure 4 drives the adjacent light sources 5 away from each other. The moving member 6 moves along the guide bracket 3 close to the middle position of the telescopic structure 4, and the moving member 6 pushes one end of the telescopic structure 4 to contract, and the telescopic structure 4 drives the adjacent light sources 5 to approach each other.

[0028] By manually moving the moving part 6, the expansion and contraction of the telescopic structure 4 is realized, and the distance between adjacent light sources 5 is adjusted, and the end of the light source 5 irradiation is concentrated on the object to be detected. When the distance between adjacent light sources 5 is short, the irradiation range of the adjustable light source mechanism for visual detection is narrow, and when the distance between adjacent light sources 5 is long, the irradiation range of the adjustable light source mechanism for visual detection is wide, thereby realizing the adjustment of the irradiation range.

[0029] The support shaft 31 is perpendicular to the guide support 3 and is arranged on the guide support 3. The middle position of the telescopic structure 4 is movably connected to the support shaft 31. A guide hole 32 is formed on the guide support 3 along the expansion or contraction direction of the telescopic structure 4. Notches 63 are formed at both ends of the moving member 6. When the moving member 6 is placed in the guide hole 32, the guide supports 3 on both sides of the guide hole 32 are placed in the notches 63, so that the moving member 6 can move smoothly along the guide hole 32.

[0030] The telescopic structure 4 includes mutually hinged unit structures 41. The unit structure 41 includes a central axis 42 and unit plates 43 arranged in a stacked manner. Exemplarily, the unit plates 43 are straight plates bent into an arc shape. The unit plates 43 are cross-stacked. The central axis 42 passes through the middle position of the unit plates 43, and the unit plates 43 rotate around the central axis 42.

[0031] Two ends of the unit plate 43 on the unit structure 41 are hinged to two ends of the unit plate 43 on the adjacent unit structure 41 .

[0032] The central axis 42 on the unit structure 41 at the middle position of the telescopic structure 4 is connected to the bracket axis 31. The central axis 42 on the unit structure 41 at one end of the telescopic structure 4 is connected to the moving member 6.

[0033] The unit plate 43 rotates in the vertical direction around the central axis 42 to complete the expansion of the telescopic structure 4. The unit plate 43 rotates in the horizontal direction around the central axis 42 to complete the contraction of the telescopic structure 4. By moving the moving member 6, the moving member 6 pulls the central axis 42, driving the unit plate 43 to rotate around the central axis 42, thereby driving the unit plate 43 on the adjacent unit structure 41 to rotate, and realizing the telescopic structure 4.

[0034] The connecting block 44 is arranged at the hinged position of the unit structures 41. Both ends of the light source 5 are connected to the connecting block 44.

[0035] When the telescopic structure 4 expands, the hinged positions of the unit structures 41 approach each other, driving the connecting blocks 44 to approach each other, so that the light sources 5 approach each other, and the irradiation range of the adjustable light source mechanism for visual inspection is narrowed. When the telescopic structure 4 contracts, the hinged positions of the unit structures 41 move away from each other, driving the connecting blocks 44 to move away from each other, so that the light sources 5 move away from each other, and the irradiation range of the adjustable light source mechanism for visual inspection is widened.

[0036] A curved surface 2 is formed on the main body 1 from top to bottom along the object to be detected. The curved surface 2 is formed on the side of the main body 1 close to the object to be detected. The light sources 5 are distributed along the curved surface 2, so that the ends of the light sources 5 are concentrated on the object to be detected, and the brightness is evenly distributed within the irradiation range of the light sources 5.

[0037] The light source 5 includes a plate body 51 and lamp beads 52 arranged side by side on the plate body 51. Both ends of the plate body 51 are connected to the connecting block 44. The lamp beads 52 are connected to the power supply through the plate body 51.

[0038] An installation ring is arranged around the visual inspection device. The main body 1 is arranged at intervals on the installation ring. So that the adjustable light source mechanism for visual inspection can irradiate around the object to be detected, avoiding irradiation dead angles.

[0039] Second Embodiment:

[0040] Figure 3 The structural schematic diagram of the adjustable light source mechanism for visual inspection according to the second embodiment of the present invention is shown. Combined Figures 1-3 As shown, a power device 61 is arranged on the moving member 6. Exemplarily, the power device 61 is a motor. A gear 62 is arranged at the driving end of the power device 61.

[0041] A rack 33 is arranged on the guiding bracket 3. The rack 33 is arc-shaped. The gear 62 meshes with the rack 33. The power device 61 drives the gear 62 to rotate, and the gear 62 rolls along the rack 33, thereby driving the moving member 6 to move along the guiding bracket 3.

[0042] By controlling the power device 61, the automatic adjustment of the telescopic structure 4 is realized, and the automatic adjustment of the irradiation range is realized.

[0043] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0044] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
