An assembly mechanism for respectively assembling a first cap and a second cap onto a first tube and a second tube is disclosed. The assembly mechanism includes a holding mechanism including a pair of clamping jigs and an actuating member. The pair of clamping jigs includes a pressing block. The actuating member is connected to the clamping jigs. The actuating member is for driving the clamping jigs to clamp the first cap and cover the first cap onto the first tube. The actuating member is further for driving the clamping jigs to clamp the second cap and cover the second cap onto the second tube after the first cap is covered on the first tube, wherein the pressing block presses the first cap when the clamping jigs cover the second cap on the second tube, so as to firmly mate the first cap with the first tube.一種組裝機構,其用來將一第一蓋體與一第二蓋體分別組裝於相鄰之一第一管體與一第二管體,該組裝機構包含有至少一夾持機構,其包含有一對夾爪以及一致動件。該對夾爪包含有一下壓突塊,該致動件連接於該對夾爪。該致動件用以驅動該對夾爪夾持該第一蓋體並蓋裝該第一蓋體於該第一管體,該致動件另用以於該第一蓋體蓋裝於該第一管體後,驅動該對夾爪夾持該第二蓋體並蓋裝該第二蓋體於該第二管體,其中該下壓突塊於該對第一夾爪蓋裝該第二蓋體於該第二管體時下壓該第一蓋體,使該第一蓋體蓋緊於該第一管體。3000‧‧‧組裝機構1‧‧‧第一夾持機構11‧‧‧夾爪110‧‧‧下壓突塊112‧‧‧夾持突塊114‧‧‧第一連接件116‧‧‧第二連接件13‧‧‧致動件15‧‧‧基座150‧‧‧滑槽2‧‧‧管體21‧‧‧第一管體21‧‧‧第一蓋體22‧‧‧第二蓋體23‧‧‧第三管體23‧‧‧第三蓋體24‧‧‧第四蓋體25‧‧‧第五管體25‧‧‧第五蓋體26‧‧‧第六蓋體27‧‧‧第七管體27‧‧‧第七蓋體28‧‧‧第八管體28‧‧‧第八蓋體3‧‧‧架體4‧‧‧移動裝置
