Referring to fig. 5, 6 and 7, in some embodiments of the present invention, the fixing assembly 320 further includes a first sliding rod 322 and a first limiting member 323, the fixing base 310 is provided with a first sliding hole 311, the first sliding rod 322 is inserted into the first sliding hole 311 and movably connected to the fixing base 310, a lower end of the first sliding rod 322 is connected to the suction cup 321, an upper end of the first sliding rod 322 is connected to the first limiting member 323, the suction cup 321 is located below the first sliding hole 311, the first limiting member 323 is located above the first sliding hole 311, and the first limiting member 323 is configured to prevent the first sliding rod 322 from moving downward to be separated from the first sliding hole 311.
The first sliding rod 322 is inserted into the first sliding hole 311, and the first sliding rod 322 can move along the axial direction of the first sliding hole 311 (even a small displacement can be generated along the radial direction of the first sliding hole 311, and the positioning can be assisted by the product placement through hole 331 a). The first limiting member 323 is disposed to prevent the first sliding rod 322 from moving downward to separate from the first sliding hole 311 when the first sliding rod 322 can move downward along the first sliding hole 311, that is, the first limiting member 323 is blocked by the fixed base 310 and cannot move downward any more, that is, the first sliding rod 322 cannot move downward any more; it should be understood that the first limiting member 323 may be integrally formed with the first sliding rod 322, that is, the first limiting member 323 and the first sliding rod 322 are integrated, the first limiting member 323 may also be a separate component mounted on the first sliding rod 322, and further, the first limiting member 323 may adjust its (up-down) position on the first sliding rod 322.
In a general mechanism, the suction cup 321 is fixed on the base; referring to fig. 7, in the present invention, when the product 100 is sucked by the suction cup 321 and placed on the inspection table 510, the pressing claw 610 presses the edge pressing member 330 (the edge pressing member 330 presses the edge portion 120 of the product 100), so that the product 100 moves downward (or tends to move downward), and since the edge pressing member 330 is spaced apart from the edge portion 120 before being pressed, the distance that the edge pressing member 330 moves downward (driving the fixing base 310 to move downward) is greater than the distance that the product 100 moves downward, at this time, if the suction cup 321 is fixed on the fixing base 310, the fixing base 310 moves downward and drives the suction cup 321 to move downward, which causes the suction cup 321 to move downward and is greater than the distance that the product 100 moves downward, thereby pressing both the suction cup 321 and the product 100, and easily making the suction effect of the suction cup 321 ineffective, and the product 100 easily drops. The first sliding rod 322 is movably connected to the fixed base 310, so that the suction cup 321 can move up and down relative to the fixed base 310, and thus when the product 100 is pressed, the suction cup 321 and the product 100 are not pressed against each other.
