[0047] Please refer to Figures 1 to 6 This utility model provides a combined visual inspection device, including a line scan camera 1 and a combined light source 2.

[0048] The combined light source 2 forms a detection channel 201, and the bottom end of the line scan camera 1 is inserted into the detection channel 201 for detecting the workpiece under test through the detection channel 201. The line scan camera 1 and the combined light source 2 are detachably connected.

[0049] The line scan camera 1 is connected to a first plug-in connector 11, and the combined light source 2 is connected to a second plug-in connector 21. The first plug-in connector 11 can be plugged into the second plug-in connector 21 so that the line scan camera 1 can supply power to the combined light source 2.

[0050] In this embodiment, on the one hand, by connecting the line scan camera 1 and the combined light source 2, the relative positions between the line scan camera 1 and the combined light source 2 are ensured. On the other hand, the first plug-in connection part 11 and the second plug-in connection part 21 are plugged in and connected, so that the line scan camera 1 supplies power to the combined light source 2, reducing the complexity of the circuit winding, thereby helping to maintain the light output effect.

[0051] In summary, by ensuring the relative position between the line scan camera 1 and the combined light source 2, the position of the line scan camera 1 relative to the combined light source 2 is made more accurate. In addition, by connecting the first plug-in connector 11 and the second plug-in connector 21, the interference of the power supply line on the light can be reduced, which is beneficial to improving the detection accuracy.

[0052] Optionally, the combined light source 2 is provided with opposing first mounting plate portions 202 and second mounting plate portions 203; the detection channel 201 is located between the first mounting plate portions 202 and second mounting plate portions 203, and the bottom end of the line scanning camera 1 is inserted between the first mounting plate portions 202 and second mounting plate portions 203. The arrangement of the first mounting plate portions 202 and second mounting plate portions 203 can more accurately position the line scanning camera 1. Preferably, the first mounting plate portions 202 and second mounting plate portions 203 are in contact with the outer side wall of the line scanning camera 1. It should also be noted that the first mounting plate portions 202 and second mounting plate portions 203 can effectively support and maintain the position of the line scanning camera 1.

[0053] Optionally, the combined light source 2 includes a housing 3, a coaxial light source 4, an arched light source 5, and a supplementary light source; the housing 3 includes a first housing plate 31 and a second housing plate 32, both of which are integrally formed; the coaxial light source 4, the arched light source 5, and the supplementary light source are installed in the housing 3 from top to bottom along the light emission direction. In this embodiment, through the multiple light irradiation of the coaxial light source 4, the arched light source 5, and the supplementary light source, the surface condition of the workpiece under test in different states can be better detected, such as the surface condition in the initial state, the preliminary processing state, the intermediate processing state, and the final forming state.

[0054] Optionally, the coaxial light source 4 includes a first lamp plate 41 and a beam splitter 42. A first housing plate 31 has a mounting groove and a first tilting limiting groove, and a second housing plate 32 has a second tilting limiting groove. The first lamp plate 41 is mounted in the mounting groove, and the two opposite ends of the beam splitter 42 are respectively embedded in the first and second tilting limiting grooves. The light emitted from the first lamp plate 41 is reflected by the beam splitter 42 and directed towards the workpiece to be measured. It should also be noted that the mounting groove defines the mounting position of the first lamp plate 41, ensuring accurate mounting. The first and second tilting limiting grooves define the mounting position of the beam splitter 42, ensuring accurate mounting.

[0055] Optionally, the first shell plate 31 and the second shell plate 32 form an arched reflector wall 501 for the arched light source 5, and the arched reflector wall 501 has a light-passing groove facing the beam splitter 42; the arched light source 5 also includes a second lamp plate 502, and both the first shell plate 31 and the second shell plate 32 are provided with a support platform 301 located on the arched reflector wall 501. The platform surface of the support platform 301 is inclined, and the second lamp plate 502 is mounted on the platform surface of the support platform 301. The light emitted from the second lamp plate 502 is reflected by the arched reflector wall 501 and then directed toward the workpiece to be measured. The second lamp plate 502 is inclined on the platform surface of the support platform 301, so that more light is directed toward the arched reflector wall 501, and finally more light is projected onto the surface of the workpiece to be measured.

[0056] Optionally, the support platform 301 has an inclined mounting surface on one side of its bottom, and the supplementary light source includes a supplementary light plate 61 mounted on the inclined mounting surface; the two supplementary light plates 61 are inclined relative to each other to form a figure-eight structure. The setting of the supplementary light plate 61 can further improve the brightness of the light, and the light is tilted towards the workpiece to be tested, which can better illuminate the side of the workpiece to be tested.

[0057] Optionally, one side of the supplementary lighting panel 61 extends upward to form a blocking portion 611 for blocking the second lighting panel 502. The blocking portion 611 can position the second lighting panel 502 to prevent it from slipping during installation. Furthermore, it should be noted that an insulating layer is provided on the blocking portion 611 to prevent leakage.

[0058] In another specific embodiment, the line scanner 1 is equipped with an elastic protrusion component, and the combined light source 2 is provided with an insertion hole corresponding to the elastic protrusion component; the elastic protrusion component can be inserted into the insertion hole to position the combined light source 2 and the line scanner 1 relative to each other. The elastic protrusion component can be inserted into the insertion hole to achieve mutual fixation between the combined light source 2 and the line scanner 1.

[0059] Optionally, the coaxial light source 4 also includes a diffuser lens 43, which is located between the first lamp plate 41 and the beam splitter lens 42. The diffuser lens 43 can homogenize the light output.

[0060] Optionally, both the outer sides of the first shell plate 31 and the second shell plate 32 are provided with heat dissipation fins, and the heat dissipation fins include a plurality of heat dissipation fins spaced apart.
