Problems solved by technology

However, after the assembly welding production line runs for a long time, the rhythm of the robot spot welding workstation may decrease accordingly, and this situation cannot be reflected in time, so there is no pre-judgment, which leads to the failure of the robot spot welding workstation It is required to complete the pre-set production plan in time, and the production plan can only be passively responded, which may affect the production of the entire welding production line

Embodiment Construction

[0017] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] The robot spot welding production line includes multiple robot spot welding workstations, each robot spot welding workstation includes multiple stations, and the spot welding robot of the same robot spot welding workstation can only weld the workpiece on one station at the same time. Such as figure 1 As shown, when the production capacity monitoring method of the robot spot welding production line is in operation, step S100 is first performed to set the bottleneck beat of each robot spot welding workstation. The bottleneck beat setting should be set according to the requirements of the production capacity plan. The bottleneck beat It should be the minimum takt that can complete the requirements of the capacity plan.

[0019] Then execute step S110, measure the welding time and the number of welding points of the spot welding robot at ...

Abstract

The invention discloses a capacity monitoring method of a robot spot-welding production line. The capacity monitoring method comprises the following steps of: calculating welding efficiency of all work positions and welding efficiency and welding beat of a corresponding robot spot-welding work station by monitoring welding time and welding spot quantity of all work positions in the robot spot-welding work station in real time; comparing the welding beat of the robot spot-welding work station with preset bottleneck beat; and then determining actual working condition of the robot spot-welding production line. The capacity monitoring method changes a fact that the condition of actual production can be only passively responded before and make the real-time understanding of the production condition and the capacity of the robot spot-welding production line possible, so that the production plan can be reasonably and timely arranged, data basis can be provided for preset maintenance equipment, and an idea of lean production of the current factories is simultaneously met.

Description

technical field [0001] The invention relates to a monitoring method, in particular to a method for monitoring the production capacity of a robot spot welding production line. Background technique [0002] The assembly welding production line includes multiple robot spot welding workstation groups, and each robot spot welding workstation includes multiple workstations, which are mainly composed of industrial robots, welding systems, tooling, etc. In the production process of the assembly welding production line, the welding time, number of welding points and welding efficiency of each station are different, so it is difficult to understand the overall working status and production capacity of the robot welding workstation in real time, and the production plan is often based on previous functions. Based on experience in production capacity. However, after the assembly welding production line runs for a long time, the rhythm of the robot spot welding workstation may decrease a...
