Rotary opening and closing device and automatic assembly module

Abstract

The invention relates to the technical field of automatic assembly, and discloses a rotary opening and closing device and an automatic assembly module. The rotary opening and closing device comprisesa linear driving mechanism, a linkage mechanism, at least one rotating shaft and at least one execution piece, wherein the output end of the linear driving mechanism can reciprocate in the first direction; the linkage mechanism is connected with the output end of the linear driving mechanism, and the linkage mechanism can convert the linear motion of the linear driving mechanism into rotary motion; each rotating shaft is arranged in the second direction, and the first end of each rotating shaft is connected with the linkage mechanism and can rotate under the driving of the linkage mechanism; and the rotating shafts of the execution pieces are arranged in a one-to-one correspondence mode, each execution piece is fixedly arranged at the second end of one rotating shaft and can rotate along with the rotating shaft, and each execution piece is configured to be connected with a movable piece on a carrier. According to the rotary opening and closing device and the automatic assembly module,the plurality of rotating shafts can be driven to rotate at the same time through one linear driving mechanism, so that the universality is good, the arrangement space of mechanism pieces can be saved, and the production yield and the working efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of automatic assembly, in particular to a rotary opening and closing device and an automatic assembly module. Background technique [0002] In the assembly and manufacturing of 3C products, it is often necessary to use a carrier to carry the product, and at the same time, it is necessary to position and clamp the product on the carrier, and the design of the carrier will be used for as many assembly processes as possible. Since the carrier will be subject to different degrees of impact, vibration and other interference during the turnover between different stations, the positioning of product parts in the carrier must meet the constraints of the "six-point positioning principle". It is necessary to maintain a certain clamping force, It is also necessary to open and close the movable parts of the carrier during assembly operations at different stations to release the corresponding operating space and meet the...

AI Technical Summary

Problems solved by technology

The opening and closing action of the rotating shaft cover is performed by the swing cylinder mechanism to provide torque, but the adaptability of this mechanism is poor, only one swing cylinder corresponds to one rotating shaft cover

However, when there are multiple stations on the carrier and it is necessary to perform opening and closing actions on multiple shaft covers, due to the limitation of the installation position, multiple swing cylinder mechanisms cannot be arranged at the same time
