[0019] The embodiments of the present utility model, for example Figures 1 to 3As shown in the figure, a camera detection machine for assembling a large and small fan door includes a carrier plate 20 and a conveying line 2 for conveying it. The conveying line 2 is a double-speed chain conveying line, and the conveying direction of the conveying line 2 is the left-right direction. A jig for mounting a fan is provided on the carrier plate 20. The jig includes at least four limit blocks 3. Preferably, six limit blocks 3 are provided. The fan is fixed in the middle of the six limit blocks 3. The six limit blocks 3 are correspondingly arranged in the front, back, left, and right four directions at the top of the carrier plate 20. Two of the limit blocks 3 are correspondingly arranged on the left and right sides of the fan, and the remaining four limit blocks are divided into two groups. The two groups of limit blocks 3 are correspondingly arranged on the front and back sides of the fan. Each limit block 3 includes a connecting portion 30 and a limiting portion 31. The connecting portion 30 and the limiting portion 31 are combined into a limit block 3 with an L-shaped cross-section. The connecting portion 30 is connected to the top of the carrier plate 20. The limiting portion 31 is arranged on the side of the top of the connecting portion 31 away from the center of the carrier plate 20. The top of the connecting portion 30 abuts against the bottom of the fan, and the side of the limiting portion 31 close to the center of the carrier plate 20 abuts against the corresponding side wall of the fan. The six limit blocks 3 fix the fan, and the fan will not move during transportation and detection, which will not affect the detection. Both the connecting portion 30 and the limiting portion 31 are of rectangular parallelepiped structure. Extension plates 300 adjacent to the bottom end of the connecting portion 30 extend from both opposite ends of the connecting portion 30. Extension plate through holes 301 are provided on the extension plates 300. A right angle is formed at the side of the top of the limiting portion 31 close to the center of the carrier plate 20. The chamfer is convenient for guiding when the fan is placed between the six limit blocks for fixing. A plurality of through holes 21 corresponding one-to-one to a plurality of fan doors on the fan are further provided on the carrier plate 20. A detection station is provided on the transportation track of the conveying line 2. An air blowing mechanism 4 for blowing air through the through holes 21 from bottom to top to the fan doors is provided at the detection station. The air blowing mechanism 4 includes an air distribution block 40 and an air blowing nozzle 41. The air distribution block 40 is arranged at the detection station. The air blowing nozzle 41 is installed at the output end of the air distribution block 40. The input end of the air distribution block 40 is connected to the air using port of the compressed air in the factory through an air pipe.

[0020] The six limit blocks 3 fix the fan on the carrier plate 20, that is, the carrier plate 20 carries the fan through the six limit blocks 3. The conveying line 2 conveys the fan to the detection position through the carrier plate 20. The air blowing mechanism 4 blows air to the fan doors of different sizes on the fan through the air distribution block 40 and the air blowing nozzle 41. The air flow passes through the avoidance through holes 21 to blow the fan doors on the fan. At this time, the vision detection unit 5 detects the opening and closing states of the fan doors to detect the quality of the fan.

There are two brackets 53 arranged at the detection station. The two brackets 53 are correspondingly located on both sides of the conveying direction of the conveyor line 2 at the detection station, that is, the two brackets 53 are correspondingly located at the left and right ends of the conveyor line 2. The XY moving platform 50 and the linear slide 21 are correspondingly arranged on the two brackets 53. The XY moving platform 50 is arranged on the right bracket 53, and the linear slide 51 is arranged on the left bracket 53. The conveying direction of the linear slide 51 is perpendicular to the conveying direction of the conveyor line 2, that is, the conveying direction of the linear slide 51 is the front-back direction. The two ends of the conveying direction of the linear slide 51 are correspondingly located at the front and back ends of the conveyor line 2. The two cameras 52 are correspondingly arranged on the XY moving platform 50 and the linear slide 51. The lenses of the two cameras 52 face downward. By moving the two cameras 52 through the XY moving platform 50 and the linear slide 51, the visual detection unit 5 can detect the fan doors at different positions on the fan.
