Such card holder is usually light and thin in structure and complex in shape, and has very high precision requirements for handling, positioning and assembly.

[0003] The semi-finished card holder needs to be transferred to the mold of the liquid silicone rubber injection molding machine for injection, and the silicone sealing ring on the card holder is formed before being taken out. In the existing process, manual or semi-automatic feeding and discharging operation is usually adopted, which has low efficiency, high labor cost and low positioning precision.
