The utility model relates to the technical field of optical cable packaging equipment, and particularly discloses anti-loosening optical cable packaging equipment which comprises a fixing frame and a bottom plate, a clamping groove is formed in the center of the surface of the fixing frame, guide rails are fixedly installed on the periphery of the surface of the clamping groove, a sliding plate is slidably connected to the surfaces of the guide rails, and a driving motor is fixedly installed on the back face of the fixing frame. Rotating discs are movably installed on the two sides of the outer surface of the guide rail, sliding grooves are formed in the two sides of the surface of the bottom plate, lead screws are fixedly installed on the surfaces of the sliding grooves, sliding blocks are in threaded connection with the surfaces of the lead screws, connecting rods are fixedly connected with the surfaces of the sliding blocks, and limiting rollers are fixedly connected with the surfaces of the connecting rods in a sleeving mode. And the sliding block is driven to slide on the sliding groove, so that the position of the limiting roller is accurately adjusted. The optical cable rings are limited by the multiple limiting rollers in different directions, it is ensured that the optical cable rings are always kept at the fixed positions in the packaging process, loosening and displacement of the optical cable rings are effectively prevented, and basic guarantee is provided for high-quality packaging.

The utility model relates to the technical field of packaging equipment, and discloses packaging equipment for seed packaging, which comprises a packaging equipment main body, a mounting seat is fixed at the bottom of the packaging equipment main body, a feed hopper is mounted at the top of the packaging equipment main body, and a mounting pad is fixed at the top of the packaging equipment main body. By arranging the auxiliary packaging mechanism, when seed packaging and packaging are carried out, vibration generated by collision of the moving rod on the feeding hopper can clear away seeds remaining on the inner wall of the feeding hopper, a feeding port is prevented from being blocked, and meanwhile the problem that part of the seeds are left on the inner wall of the feeding hopper and possibly mixed into packaging bags for subsequent seed packaging is solved; the packaging quality of seed packaging is improved, and the situation that different seeds are mixed is reduced; by arranging the closing mechanism, when the movable door is locked after being closed, locking after the movable door is closed can be conveniently completed, opening operation of the movable door is simple and convenient, and operation of a user is facilitated.

本实用新型提供了一种半导体器件焊料阻挡结构，涉及半导体技术领域，包括设置在芯片上的导电连接柱，导电连接柱远离芯片一端设置焊料连接层，导电连接柱外周设置环形凹槽，环形凹槽内设置阻挡环。本实用新型中，通过在导电连接柱外侧设置阻挡环，阻挡环能够阻挡锡料沿导电连接柱延伸，减少回流焊过程中虚焊或短路的问题，提高了封装品质。
