Seat cushion positioning mechanism and control method thereof

Abstract

The invention discloses a seat cushion positioning mechanism and a control method of the seat cushion positioning mechanism. The seat cushion positioning mechanism comprises a left clamping device, a right clamping device, a front hold-down device and a rear hold-down device, wherein the left clamping device, the right clamping device, the front hold-down device and the rear hold-down device are installed on a basal plane and used for fixing a seat cushion; a clamping part of the left clamping device faces right, a clamping part of the right clamping device faces left, and both a clamping part of the front hold-down device and a clamping part of the rear hold-down device face downward and are located between the clamping part of the left clamping device and the clamping part of the right clamping device. In the clamping and positioning process, the clamping part of the left clamping device and the clamping part of the right clamping device abut against the left side face and right side face of the seat cushion respectively, the clamping part of the front hold-down device compresses a seat basin downward, and the clamping part of the rear hold-down device compresses the rear portion of the seat cushion downward, wherein the seat basin is installed on the seat cushion in advance. The seat cushion positioning mechanism can realize accurate and stable clamping and positioning of the seat cushion on an automated assembly line, thereby facilitating automated control and management of positioning.

Description

technical field [0001] The invention relates to the technical field of fixtures for auto parts, in particular to a seat frame positioning mechanism and a control method for fixing the seat frame and the seat pot when the seat frame and the seat pot are connected. Background technique [0002] As the final assembly plant of car seats is a labor-intensive area, the traditional assembly of seat frames and seat pans is done manually. The demand for manual work is not as good as that of automated equipment in terms of labor cost, process, quality, efficiency, and working hours. The use of automated equipment can not only reduce the demand for personnel, but also improve the process, quality, efficiency, and working hours. Therefore, an automatic wire feeding and tightening system has appeared for the assembly of the seat frame and seat pan. In this system, the workers pre-install the workpiece on the line, and after the confirmation is completed, it flows to the assembly station....

[0002] As the final assembly plant of car seats is a labor-intensive area, the traditional assembly of seat frames and seat pans is done manually. The demand for manual work is not as good as that of automated equipment in terms of labor cost, process, quality, efficiency, and working hours. The use of automated equipment can not only reduce the demand for personnel, but also improve the process, quality, efficiency, and working hours. Therefore, an automatic wire feeding and tightening system has appeared for the assembly of the seat frame and seat pan. In this system, the workers pre-install the workpiece on the line, and after the confirmation is completed, it flows to the assembly station. The second part of the workpiece The secondary positioning and assembly are all completed by mechanical equipment and controlled by automation. After the assembly line pallet is lifted and positioned in place, it is assembled by mechanical equipment. After the assembly is completed, the assembly line pallet is positioned and lifted by the lifting mechanism. The pallet returns to the assembly line and flows to the next stage. One station, and because the seat frame and the seat basin are only manually pre-assembled, the seat frame is supported on the pallet, and the seat pot is pre-installed on the seat frame only to pre-position the seat frame and the seat pot, and the tray on the assembly line After flowing to the assembly station, before the automatic assembly of mechanical equipment, it is necessary to perform secondary clamping and positioning on the seat frame and seat basin. Therefore, a positioning device is required to perform horizontal and vertical positioning of the seat frame and seat basin. position

[0003] The disadvantage of the existing technology is: after the manual assembly of the seat frame and the seat basin is changed to automatic assembly, after the workpiece is pre-assembled on the line and flowed to the assembly station, secondary positioning is required, but there is no such positioning of the workpiece at present. clamping mechanism
