Carrier transmission device, transmission system and carrier transmission method

A transmission system, comprising:

• a first carrier adapted to be loaded with product components and including a first toothed rack;
• and
• a carrier transmission device, including:
• a slide rail extending along a transmission direction of the first carrier and receiving and guiding the carrier to slide along the slide rail;
• a pair of toothed gears spaced by a predetermined distance in the transmission direction and engaging with the rack to drive the first carrier to slide in the transmission direction on the slide rail;
• and,
• an elastic blocking device contacting a toothing of the first rack and applying a friction resistance on the first rack opposite to the transmission direction.

A carrier transmission device, comprising:

• a slide rail extending along a transmission direction of a carrier to be transmitted;
• a carrier slidably supported on the slide rail;
• a rack defining teeth and extending along the transmission direction and connectable to, or integrally formed on, the carrier;
• a pair of gears spaced by a predetermined distance in the transmission direction and adapted to engage with the teeth of the rack and drive the carrier to slide in the transmission direction on the slide rail;
• and
• a blocking device arranged between the pair of gears in the transmission direction and fixed relative to the slide rail, the blocking device engaging with the teeth of the rack and applying a friction resistance on the rack opposite to the transmission direction.
