[0032] A 3D line scan camera, also known as a laser profilometer or 3D line laser measuring instrument, works by projecting a line laser plane onto the surface of an object to obtain the three-dimensional coordinates of the point where the plane intersects the surface of the object to be measured, and then calculating the depth information of the object.

[0033] The clamping and positioning mechanism 9 is composed of a fixture table 91, a product fixture 92, a pressing mechanism 93, a slider 94, a linear slide 95 and a linear drive mechanism. The linear slide 95 and the linear drive mechanism are both fixedly mounted on the base 13. The slider 94 is fixedly mounted on the bottom of the fixture table 91. The product fixture 92 is fixedly mounted on the fixture table 91. The product fixture 92 has a fixture front hole 921 and a fixture rear hole 922. The slider 94 is also slidably mounted on the linear slide 95. The fixture table 91 reciprocates along the linear slide 95 through the linear drive mechanism and uses the front 3D line scan camera 6 and the back 3D line scan camera 7 to perform flatness detection. The pressing mechanism 93 is fixedly mounted on both sides of the fixture front hole 921 and the fixture rear hole 922 of the fixture table 91.

[0038] The three-axis manipulator can realize XYZ axis movement, and the rotary motor can adjust the angular position of the negative pressure suction nozzle so that the negative pressure suction nozzle can suck up the plane position of the fan product 10 and grab and carry the fan product 10 through the negative pressure suction nozzle.

The piston rod of the transverse telescopic cylinder retracts to drive the cylinder body of the longitudinal telescopic cylinder to approach the jig table 91. When the pressure rod is above the pressing point of the fan product 10, the piston rod of the longitudinal telescopic cylinder retracts to drive the combination of the pressure plate and the pressure rod to move downward, and the fan product 10 placed in the front hole 921 and the rear hole 922 of the jig is pressed and fixed by the pressure rod.

[0042] An upper support frame protective cover 12 is also fixedly mounted on the top of the lower frame 11 to protect the internal structure of the equipment.

[0043] A position sensor 21 is fixedly installed on the loading assembly line 2. The position sensor 21 is connected to the control module through a circuit. The position of the fan product 10 is detected by the position sensor 21 and fed back to the control module, so as to determine the timing for the loading robot 4 to grab the fan product 10 from the loading assembly line 2.

[0044] The fan product 10 flows into the loading line 2 through the loading line, and the loading robot 4 grabs the fan product 10 on the loading line 2 and puts it into the front hole 921 and the back hole 922 of the product fixture 92. The lower parts of the front hole 921 and the back hole 922 of the fixture pass through the fixture table 91 and the product fixture 92, so the back 3D line scan camera 7 can scan the bottom of the back of the fan product 10, and press the fan product 10 into the front hole 921 and the back hole 922 of the fixture through the pressing mechanism 93. The linear drive mechanism drives the product fixture 92 and the fan product 10 along the straight line. The linear slide 95 moves past the front 3D line scan camera 6 and the back 3D line scan camera 7 to perform automatic scanning and detection on the front and back sides. The front 3D line scan camera 6 and the back 3D line scan camera 7 send the detection data to the control module. The control module judges and analyzes the plane detection information of the fan product 10. The linear drive mechanism drives the product fixture 92 and the fan product 10 to reset along the linear slide 95. The pressing mechanism 93 releases the pressing and positioning of the fan product 10. The unloading robot 5 grabs the fan product 10 from the front hole 921 and the back hole 922 of the fixture and puts it into the unloading assembly line 3 for outflow.
