Embodiment 1

[0125]A mixed-flow coating line for standard cars and vans, comprising a pre-treatment track 1, a primer treatment catenary 2 and a topcoat treatment catenary 3, the pre-treatment track 1 is located on one side of the primer treatment catenary 2 , the other side of the primer treatment catenary 2 is a topcoat drying catenary 3; the pretreatment track 1 is a circular track, and the primer treatment catenary 2 and the topcoat treatment catenary 3 are ring A catenary, a plurality of electric hoists 15 slidingly matched with the pretreatment track 1 are hung, a mobile hanger 4 is hung on the bottom of the electric hoist 15, and a lifting lug 41 is arranged on the top of the mobile hanger 4, and the workpiece hanger The bottom is provided with a plurality of hanging holes 42, the primer-treated catenary 2 is provided with a primer drying catenary hook 51, and the top-coated catenary 3 is provided with a topcoat-treated catenary hook 52 ; The bottom of the ring-shaped pre-processing...

Embodiment 2

[0144] Embodiment 2 basic content is the same as embodiment 1, and its difference is:

[0145] In the fifth step, after the mobile hanger 4 that hangs the primer treatment workpiece breaks away from the primer treatment catenary 2 and moves to the top of the second translation trolley 62, it is judged whether the workpiece hung on the mobile hanger 4 is a standard or not. Car floor 102;

[0146] If the workpiece hanging on the mobile hanger 4 is not the standard compartment floor 102, then continue to carry out the topcoat catenary transfer;

[0147] If the workpiece hanging on the mobile hanger 4 is the standard compartment floor 102, then move the second translation dolly 62 to the transfer station 18 along the translation dolly track 17, and make the second translation dolly 62 and the transfer high roller rack 36 top The roller table 7 is connected, and the second translation trolley 62 is controlled to rotate with the top roller 71 of the transfer high-position roller fr...

Embodiment 3

[0149] Embodiment 3 basic content is the same as embodiment 2, and its difference is:

[0150] In the eighth step, if the finished workpiece hung on the mobile hanger 4 is the side panel 103 of the standard compartment or the front and rear panels 104 of the standard compartment, the front and rear panel removal trailer 91 is moved to control the lifting of the removal and hanging station 14. On the platform 8, the lifting platform 8 that controls the lifting station 14 rises, and the lifting platform 8 drives the front and rear panel trailers 91 to rise until the side panels 103 of the standard compartment or the front and rear panels 104 of the standard compartment are placed on the front and rear panel trailers. 91 and coordinate with the baffle plate 911, the operator removes the hook, the standard compartment side panel 103 and the standard compartment front and rear panels 104 are separated from the mobile hanger 4, the removal and hanging is completed, and the standard c...

Abstract

The invention relates to a mixed flow coating line and a mixed flow coating method for standard compartment and van vehicles. The mixed flow coating line comprises an annular pretreatment track, a primer treatment suspension chain and a finish treatment suspension chain, wherein a hanging station, a pretreatment electrophoresis chamber, a pretreatment discharging station and a picking and hangingstation are sequentially arranged below the pretreatment track in the running direction of an electric hoist; a primer feeding station, a primer drying furnace and a primer discharging station are sequentially arranged below the primer drying suspension chain in the rotating direction of a suspension chain track; a finish feeding station, a paint spraying chamber, a finish drying furnace and a finish discharging station are sequentially arranged below the finish treatment suspension chain in the rotating direction of the suspension chain track; and to-be-coated parts are suspended on a movablehanging bracket for conveying and a high-position roller way and a transverse moving trolley are matched through a descending track, a low track and an ascending track which are arranged on the suspension chains for rotary hanging and feeding and discharging. According to the design, mixed flow production of the standard compartment and van vehicles is realized through unique coating line arrangement and suspension conveying and rotary hanging modes.

Description

technical field [0001] The invention relates to a mixed-flow coating line and its mixed-flow coating method, in particular to a mixed-flow coating line and its mixed-flow coating method for standard compartments and vans, and is particularly applicable to the mixed-flow coating of standard compartments and vans. painting. Background technique [0002] In the domestic carriage painting production line, the painting of standard carriages often adopts the method of fragmented dispersion, and the conveying system is a low-cost ordinary catenary chain, while the carriage painting of vans is generally conveyed by ground rollers. If standard vans and vans are produced at the same time, two production lines need to be invested. And in the coating process, there are different process requirements for different workpieces, resulting in differences in the processes required for different products, so it is difficult to produce different products on the same line, and the cost of build...
