Description

Technical Field

[0001] The utility model relates to the field of automobile seat processing, in particular to a heating transmission mechanism for a backrest frame of an automobile seat. Background Art

[0002] The felt is pasted on the car seat back frame mainly through drawings and data information, according to the amount of glue, position and gram weight, the backrest and the felt are closely fitted and positioned, and finally the felt and the backrest frame are closely fitted to achieve the required pull-off force. Because the spray glue is a hot melt glue, the glue melts at a certain temperature and is sprayed on the seat frame. When the temperature of the seat frame is low, the glue will solidify prematurely and affect the fitting effect of the felt. Therefore, before spraying the glue, the seat frame needs to be heated in a heating furnace. The operation method of the prior art is that workers manually carry the seat frame to the heating furnace for heating. The disadvantage is that the manual handling efficiency is low, and the seat frame needs to be positioned again after heating to complete the fitting of the felt, which wastes production costs. Summary of the invention

[0003] In view of the deficiencies of the prior art, the utility model has developed a heating and transmission mechanism for the frame of a car seat backrest. The technical solution adopted by the utility model is: a heating and transmission mechanism for the frame of a car seat backrest, characterized in that it includes a base 1, a frame 2, a positioning platform 13 and a transmission mechanism 14; the base 1 is fixedly connected to the frame 2; the base 1 is connected to the transmission mechanism 14; the positioning platform 13 is arranged below the frame 2; the first guide shaft 3 and the second guide shaft 17 are respectively fixedly arranged on the base 1; the first lifting cylinder 5 and the second lifting cylinder 19 are respectively fixedly arranged on the base 1; the first guide shaft 3 and the second guide shaft 17 pass through the first lifting plate 4 and the second lifting plate 18 respectively; the first lifting plate 4 and the second lifting plate 18 are respectively fixedly connected to the piston rods of the first lifting cylinder 5 and the second lifting cylinder 19; the A guide rail 7 and a second guide rail 21 are fixedly arranged on the first lifting plate 4 and the second lifting plate 18 respectively; the first fork plate 8 and the second fork plate 22 are slidably connected to the first guide rail 7 and the second guide rail 21 respectively; the first fork cylinder 6 and the second fork cylinder 20 are fixedly arranged on the first lifting plate 4 and the second lifting plate 18 respectively; the first fork plate 8 and the second fork plate 22 are fixedly connected to the piston rods of the first fork cylinder 6 and the second fork cylinder 20 respectively; the first fork claw 15 and the second fork claw 16 are fixedly arranged on the first fork plate 8 and the second fork plate 22 respectively; the upper crossbeam 9 is fixedly arranged on the upper part of the frame 2; the first positioning pin group 10, the second positioning pin group 11 and the third positioning pin group 12 are fixedly arranged on the upper crossbeam 9 respectively.

[0004] The benefits of the utility model are as follows: since a positioning platform is used to complete the pre-heating positioning of the seat frame, the fork cylinder is used to drive the fork plate so that the fork claws pick up the workpiece, and then the lifting cylinder is used to lift the workpiece, and the positioning pin group is used to position the workpiece, and finally the conveying mechanism is used to convey the workpiece to the heating furnace. After the heating is completed, the workpiece is unloaded to the positioning platform and the felt bonding operation is carried out, which greatly improves the production efficiency and reduces the production cost.
