The detailed structure of the conveying mechanism 200 will now be described with reference to fig. 1 and 6.

As shown in fig. 6, the first detection mechanism 300 includes a limiting plate 310, a pushing assembly 320, and a first detection assembly 330. Wherein, the limiting plate 310 is disposed on the conveying mechanism 200 along the X direction, that is, the limiting plate 310 is disposed on the conveyor belt 240, the pushing assembly 320 is configured to push the fitting 1000 on the conveyor belt 240 of the conveying mechanism 200 to the position of the fitting limiting plate 310, and the first detecting assembly 330 can detect the distance of the fitting 1000 away from the end face 1100 of the limiting plate 310, thereby detecting the profile dimension of the fitting 1000 along the Y direction.

Here, the stopper plate 310 and the pushing assembly 320 cooperate with each other to fix the position of the fitting 1000 on the conveyor belt 240 in the Y direction, so as to improve the detection accuracy of the first detecting assembly 330. In order to avoid the output end of the pushing component 320 from damaging the external shape of the fitting 1000, a buffer member 322, such as a sponge, foam, rubber, etc., is disposed on the output end 1100 of the pushing component 320 to protect the fitting 1000.

The limiting tool 431 is detachably connected with the detecting platform 411, the limiting tools 431 are multiple groups, and the first limiting part 4311 and the second limiting part 4313 of the multiple groups of limiting tools 431 are matched with the fittings 1000 with different sizes, so that the detecting second detecting assembly 430 can be suitable for the fittings 1000 with different sizes, and the application range of the second detecting assembly 430 is enlarged. Specifically, the limiting tool 431 is fixed on the detection platform 411 through a fixing member. In this example, the limiting tool 431 includes a mounting plate 4314, the second limiting member 4313 is disposed on the upper end surface 1100 of the mounting plate 4314, when the limiting tool 431 is replaced, only the mounting plate 4314 needs to be replaced, and the limiting tool 431 realizes modularized management, so that replacement and assembly are convenient.

In order to facilitate the rapid assembly of the limiting tool 431, a limiting hole is formed in the limiting platform, a limiting column is arranged on the lower end face 1100 of the limiting tool 431, and during assembly, the limiting column can be inserted into the limiting hole so as to facilitate the rapid assembly of the limiting tool 431. Meanwhile, the number of the limiting columns is two, three or more, so that the limiting effect is improved. Further, the limiting columns can be arranged along the X direction or the Y direction, so that the error in the installation direction of the limiting tool 431 is avoided, and the fool-proof effect is achieved.

The third detecting member 442 may be any one of an optical distance sensor, an infrared distance sensor, an ultrasonic distance sensor, etc., which are commonly used distance sensors, and is low in cost and advantageous in ensuring detection accuracy.

Since the third detecting member 440 is used for detecting the assembly size of the upper end 1100 of the fitting 1000, when the size of the fitting 1000 is changed, the position of the third limiting member 441 relative to the first limiting member 4311 may be changed.

The structure of the first guide 4432 is advantageous in improving the stability of the reciprocating movement of the second driving member 4433 in the X direction.
