Description

CROSS-REFERENCE TO RELATED APPLICATION The present disclosure is based on Chinese Patent Application No. 202311293186.X filed on October 8, 2023 and titled "BLOCKING MECHANISM AND LOGISTICS CONVEYOR LINE", and claims the priority to the Chinese patent application, which is incorporated herein by reference in its entirety. TECHNICAL FIELD New energy batteries are increasingly more widely applied in life and industry. For example, new energy vehicles equipped with batteries have been widely used. In addition, batteries are increasingly applied in the field of energy storage and the like. The present disclosure relates to the field of logistics, and in particular to a blocking mechanism and a logistics conveyor line. BACKGROUND In the related art, in order to coordinate with the production rhythm, a blocking mechanism is generally provided between the previous and subsequent workstations on the logistics conveyor line for transporting workpieces. When the subsequent workstation is running, the blocking mechanism blocks the workpiece on the previous workstation; and when the subsequent workstation needs to be docked with the previous workstation and stops running, the blocking mechanism allows the workpiece on the previous workstation to be transferred to the subsequent workstation. The current blocking mechanism cannot be applied to operations in which the movement direction of the logistics conveyor line of the subsequent workstation is bidirectional so that the workpiece is transferred between multiple layers of logistics conveyor lines. SUMMARY OF THE INVENTION In view of this, embodiments of the present disclosure are intended to provide a blocking mechanism and a logistics conveyor line that can effectively solve the production rhythm problem in transferring workpieces between multiple layers of logistics conveyor lines. To achieve the above objective, an embodiment of the present disclosure provides a blocking mechanism, including a blocking assembly and a trigger member. The blocking assembly includes a transmission member, a blocking member, and an elastic member. The blocking member includes a first position for blocking and a second position for unblocking. The transmission member is connected to the blocking member, and the elastic member can place the blocking member in the first position. The trigger member can contact the transmission member in two opposite directions to place the blocking member in the second position. The elastic member stores elastic potential energy under the action of the transmission member, and when the trigger member is disengaged from the transmission member, the elastic member can restore the blocking member from the second position to the first position. The trigger member can push the transmission member, and the transmission member drives the blocking member to move, so that the blocking member reaches the second position for unblocking. When the trigger member is not in contact with the transmission member, the elastic member returns the blocking member to the first position to resume blocking. The trigger member can contact the transmission member in two opposite directions, so that the workpiece can be transferred between multiple layers of conveyor lines. In some embodiments, the blocking assembly further includes a base, and the blocking member is rotatably connected to the base. The transmission member includes a push rod, which can move linearly relative to the base. One end of the push rod is connected to the blocking member, and the other end of the push rod can contact the trigger member. The base serves to support the push rod and the blocking member. The push rod can move linearly relative to the base, and the blocking member is rotatably connected to the base, thereby converting the linear motion of the push rod into rotation of the blocking member, thus realizing the state change of the blocking member between the first position and the second position. In some embodiments, the base has a through hole, and the push rod passes through the through hole. The push rod is restricted to make linear motion in the axial direction of the through hole. In some embodiments, the base includes a first base and a second base, one of the first base and the second base has a slide rail, the other of the first base and the second base has a slide groove, and the first base and the second base are slidably mated through the slide rail and the slide groove; the blocking member is rotatably connected to the first base, and the push rod is fixedly connected to the second base. The slide rail and the slide groove are slidably mated, and the second base can make linear motion relative to the first base, together with the movement of the push rod fixed thereon, so that the push rod makes linear motion. The use of a slide rail and slide groove structure can effectively reduce costs. In some embodiments, the base includes a base body and a linear bearing. The blocking member is
