Description

Technical Field

[0001] This utility model relates to the field of logistics equipment technology, and in particular to a flipping mechanism. Background Technology

[0002] In automated production lines, material flipping is a critical process in assembly, inspection, and packaging. For example, in automotive parts assembly, appliance casing processing, and large sheet metal painting, it is often necessary to flip workpieces from a horizontal to a vertical position (or vice versa) to meet process requirements or spatial layout needs. Traditional flipping mechanisms generally use hydraulic cylinders or motors to drive the shaft and directly rotate the grippers, but these methods have the following significant drawbacks in practical applications:

[0003] First, the drive consumes a lot of energy and the system is inefficient.

[0004] When flipping workpieces with large loads (such as metal castings and large injection molded shells), the drive mechanism needs to overcome the huge overturning moment generated by the weight of the workpiece. If no counterweight is set, the hydraulic system or motor needs to continuously output high power, which will significantly increase the long-term operating cost, especially in continuous operation scenarios.

[0005] Second, poor clamping stability, making the workpiece easily damaged.

[0006] Existing clamping assemblies mostly use a single cylinder to drive the moving clamping plate, which lacks anti-sway design. When clamping irregular workpieces (such as irregularly shaped packaging boxes), the moving clamping plate is easily jammed or tilted due to uneven force, which causes the workpiece to shake during the flipping process, increases the instantaneous load on the drive mechanism, and accelerates the wear of transmission components.

[0007] Third, the counterweight adjustment is inflexible and has poor adaptability.

[0008] Although some improvement solutions add counterweights, most of them use bolt-fixed structures. When the production line switches to different specifications of workpieces, it is necessary to stop the machine and manually disassemble / add counterweights. For flexible production lines with multiple varieties, this kind of design seriously restricts the utilization rate of equipment. Summary of the Invention

[0009] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a flipping mechanism.
