[0061] In this embodiment, the vision detection system includes a vision detection bracket, a camera module mounted on the vision detection bracket, and a light source device mounted on the vision detection bracket.

[0062] See Figure 1 and Figure 2 , the vision detection bracket includes a bottom plate platform 1, a vertical guide rail 2, a camera bracket assembly 3, and a light source bracket assembly 4. The bottom plate platform 1 is used to place the workpiece to be measured; the vertical guide rail 2 is fixed on the bottom plate platform 1; the camera bracket assembly 3 is slidably mounted on the vertical guide rail 2 and is used to clamp and fix the camera module; the light source bracket assembly 4 is slidably mounted on the vertical guide rail 2 and is located below the camera bracket assembly 3 and is used to mount and fix the light source device.

[0063] For the vision detection bracket and the vision detection system provided in this embodiment, after placing the workpiece to be measured on the bottom plate platform 1, sliding the light source bracket assembly 4 up and down can adjust the relative position between the light source device and the workpiece to be measured, and sliding the camera bracket assembly 3 up and down can adjust the relative position between the camera module and the workpiece to be measured, thereby solving the problem that the relative positions of the camera module and the light source device with respect to the workpiece to be measured cannot be adjusted.

[0064] In this embodiment, the vision detection bracket further includes two longitudinal sliding tables 5 that are slidably connected to the vertical guide rail 2 up and down. Among them, the camera bracket assembly 3 is mounted and fixed on the longitudinal sliding table 5 at a higher position, and the light source bracket assembly 4 is mounted and fixed on the longitudinal sliding table 5 at a lower position.

[0065] Optionally, the longitudinal sliding table 5 includes a sliding table body 501 and a first hand-tightening bolt 502. The sliding table body 501 is slidably connected to the vertical guide rail 2 up and down; the first hand-tightening bolt 502 passes through the sliding table body 501 in a threaded manner and abuts against the vertical guide rail 2.

[0066] When it is necessary to adjust the up and down position of the sliding table body 501, loosen the first hand-tightening bolt 502, and the first hand-tightening bolt 502 disengages from the vertical guide rail 2, then the sliding table body 501 can be slid up and down; after the adjustment is completed, tighten the first hand-tightening bolt 502 so that the first hand-tightening bolt 502 presses against the vertical guide rail 2, thereby locking the sliding table body 501 and the vertical guide rail 2 to prevent the sliding table body 501 from sliding down under the action of gravity.

[0067] Optionally, the camera bracket assembly 3 is detachably mounted on the corresponding longitudinal sliding table 5.

[0068] In this embodiment, the vision detection bracket further includes a first fixing block 6 and a second fixing block 7. The first fixing block 6 is fixedly installed on the camera bracket assembly 3, and the first fixing block 6 is provided with a trapezoidal boss 601; the second fixing block 7 is fixedly installed on the higher longitudinal slide 5, and a dovetail groove for upper and lower plug-in connection with the trapezoidal boss 601 is formed on the top surface of the second fixing block 7.

[0069] Wherein, a blocking portion is provided at the lower end of the dovetail groove to limit the trapezoidal boss 601 from sliding out of the dovetail groove downward. Through the plug-in connection structure of the trapezoidal boss 601 and the dovetail groove, the rapid installation and disassembly of the camera bracket assembly 3 can be realized.

[0070] See Figure 3 , further, the vision detection bracket further includes a fixing frame 8, a rotating plate 9, and a second hand-tightening bolt 10. The fixing frame 8 is fixedly installed on the first fixing block 6, and a rotating groove 801 is provided at the middle position of the fixing frame 8; one end of the rotating plate 9 is fixedly installed on the camera bracket assembly 3, and the other end is rotatably connected with the rotating groove 801 around a horizontal axis. After the second hand-tightening bolt 10 is screwed through the fixing frame 8, it abuts against the rotating plate 9. It should be noted that by loosening the second hand-tightening bolt 10, the rotating plate 9 can be rotated, and then the shooting angle of the camera module on the camera bracket assembly 3 can be adjusted. After the adjustment is completed, by tightening the second hand-tightening bolt 10, the rotating plate 9 can be locked.

[0071] In this embodiment, the camera bracket assembly 3 includes a U-shaped frame 301, a guide rod 302, two oppositely arranged camera clamping plates 303, an adjusting screw rod 304, and a screw rod cap 305. The guide rod 302 is fixed in the U-shaped frame 301. The two camera clamping plates 303 are slidably connected to the U-shaped frame 301 along the guide rod 302. The adjusting screw rod 304 is rotatably installed on the U-shaped frame 301 and is threadedly connected to the two camera clamping plates 303; wherein, the thread rotation directions of the adjusting screw rod 304 corresponding to the two camera clamping plates 303 are opposite. The screw rod cap 305 is fixed at the end face of the adjusting screw rod 304. By turning the screw rod cap 305, the two camera clamping plates 303 can be made to approach each other to clamp the camera module or move away from each other to release the camera module.

[0072] Optionally, protective pads 306 are provided on the surfaces of the two camera clamping plates 303 that approach each other to prevent damage to the camera module.

[0073] The light source support assembly 4 includes a first longitudinal plate 401a, a connecting cross plate 402, and a second longitudinal plate 401b arranged in a U-shaped structure. Among them, the connecting cross plate 402 is provided with a cross plate long hole 4021 for tightly connecting with the first longitudinal plate 401a or the second longitudinal plate 401b; both the first longitudinal plate 401a and the second longitudinal plate 401b are provided with longitudinal plate long holes 4011 for tightly connecting with the light source device.

[0074] The setting of the cross plate long hole 4021 can adjust the distance dimension between the first longitudinal plate 401a and the second longitudinal plate 401b longitudinally, so that the light source device approaches or moves away from the workpiece to be measured longitudinally. The longitudinal plate long hole 4011 can adjust the position of the light source device transversely, so that the light source device approaches or moves away from the workpiece to be measured transversely.

[0075] In summary, the vision detection support and the vision detection system provided by this embodiment have the following advantages:

[0076] ① By sliding the light source support assembly 4 up and down, the relative position between the light source device and the workpiece to be measured can be adjusted. By sliding the camera support assembly 3 up and down, the relative position between the camera module and the workpiece to be measured can be adjusted, thereby solving the problem that the relative positions of the camera module and the light source device with respect to the workpiece to be measured cannot be adjusted.

[0077] ② Through the plug-in connection structure of the trapezoidal boss 601 and the dovetail groove, the rapid installation and disassembly of the camera support assembly 3 can be realized.

[0078] ③ Loosen the second hand-tightening bolt 10, and then the rotating plate 9 can be rotated to adjust the shooting angle of the camera module on the camera support assembly 3.
