Embodiment 2
[0055] Such as image 3 As shown, in order to prevent repeated tightening operations and achieve a better error prevention effect, this embodiment also adds some functions on the basis of embodiment 1, as follows:
[0056] When the second judging module judges that the wrench has completed one operation multiple times within 0.2-1 second, it indicates that a repeated tightening operation has been performed, and this repeated tightening operation should not be regarded as one operation, so the controller 3 in this Within 0.2-1 second, only one is added to the value of the actual number of operations of the wrench, thereby well preventing repeated tightening operations.
[0057] In addition, the error proofing device also includes an indicator light 9, which is used to indicate the wrench that the lock is in an open state.

The invention provides a mistake-proofing device, a mistake-proofing method and a mistake-proofing system. The mistake-proofing device comprises an identifying unit for identifying a product, a controller, tools, a lockset for locking various tools, a first judgment unit for judging whether the use of the tools is finished, and a second judgment unit for judging whether one-time operation of the tools is finished, wherein the controller stores product mistake-proofing information and is used for controlling the lockset of the currently to-be-used tool to be in the opening state until the first judgment unit judges that the use the tool is finished, and outputting prompt information when the actual operation time of the used tool is not identical to the targeted operation time. The mistake-proofing device disclosed by the invention is simple in structure, can avoid wrong tool and part neglecting problems when the part is assembled, effectively conducts mistake-proofing control on the part assembly process, increases the production efficiency of the product, and lowers the production cost.
Description
technical field [0001] The invention relates to the technical field of workpiece assembly, in particular to an error prevention device in the workpiece assembly process, an error prevention method realized by the error prevention device, and an error prevention system including the error prevention device. Background technique [0002] At present, many products such as engines are generally produced with a variety of workpieces. During the assembly process of the product, a large number of parts need to be installed through assembly tools. Due to the different types, quantities and installation requirements of different parts, the assembly tools for assembling these parts are also different. different, and the operation requirements and number of operations realized by each assembly tool are also inconsistent. [0003] When existing parts are installed by means of assembly tools, many operators use the assembly tools to complete the assembly of parts. However, because mass ...
