[0051] In actual use, according to the relative angle between the desiccant and the first cylinder clamp 18, the second driving member drives the second bracket 17 to rotate with the first cylinder clamp 18, thereby changing the relative angle between the first cylinder clamp 18 and the desiccant, so that the first cylinder clamp 18 can accurately clamp the desiccant, thereby improving the feeding yield of the desiccant. The third driving member is used to drive the suction nozzle 19 to move up and down, so that the suction nozzle 19 is close to or away from the humidity card, thereby ensuring that the suction nozzle 19 accurately sucks the humidity card, thereby improving the feeding yield of the humidity card.

[0053] A sixth driving member is installed on the third bracket 21, and the pneumatic scissors 24 are installed on the output end of the sixth driving member. The sixth driving member drives the pneumatic scissors 24 to reciprocate between the second cylinder clamp 23 and the guide cylinder 25. In actual use, according to the actual size of the desiccant, the sixth driving member drives the pneumatic scissors 24 to move up and down, thereby changing the position of the pneumatic scissors 24 relative to the desiccant, so that the pneumatic scissors 24 can smoothly cut desiccants of various sizes.

[0054] The third bracket 21 is provided with a guide unit 28, and the pneumatic scissors 24 are located between the guide unit 28 and the guide cylinder 25.

[0055] The guide unit 28 is used to guide the moving direction of the desiccant tape released by the tray 22, so as to prevent the desiccant tape released by the tray 22 from being skewed during movement and being used improperly. The rotation of the guide wheel 29 reduces the contact wear between the desiccant tape released by the tray 22 and the guide wheel 29, thereby improving the feeding yield of the desiccant tape. The inner side wall of the annular blind groove 31 is used to block and limit the two sides of the desiccant tape released by the tray 22, so as to prevent the desiccant tape released by the tray 22 from being separated from the guide wheel and moving improperly.

[0059] By providing the accommodating blind groove 39 and the supporting protrusion 41, the contact area between the circuit board and the carrier 38 is reduced, and the air in the gaps between the multiple supporting protrusions 41 is used to reduce the adhesion between the circuit board and the carrier 38, ensuring that the circuit board can be easily removed from the carrier 38, thereby avoiding the circuit board and the carrier 38 from adhering to each other and causing poor circuit board feeding.
