Technical field

The invention relates to the technical field of automobile painting equipment, in particular to a vertical double-chain conveyor.

Background technique

With the rapid economic growth, China ’s car sales have ranked first in the world for three consecutive years. Under the situation of accelerating the transformation of economic growth mode, the replacement of expensive imported equipment with cost-effective domestic equipment has also become the competitiveness of the domestic car market. inevitable choice. Coupled with the rapid rise of domestic human resource costs and the low degree of intelligent control of old products, domestic automobile manufacturers have been forced to upgrade and upgrade. In addition, in recent years, the market demand for trucks, special vehicles, agricultural vehicles and construction machinery has also increased year by year.

However, China's auto industry's dependence on imports of core equipment and key components has not changed. According to the survey, the current domestic automobile production equipment is at least 10 years behind the international advanced level. The outstanding performance is in three aspects: first, the sustainable utilization rate of the equipment is low, and the life of imported equipment is more than 3 times the life of domestic equipment; second, the accuracy is poor, and the accuracy of imported equipment is often more than 10 times the accuracy of domestic equipment; third, intelligent The level is low, domestic automobile production equipment still needs a lot of manual operation, the product's intelligence and reliability are not high, and it covers a large area, consumes energy and causes serious pollution.

At present, the domestic automobile coating production line mainly uses a single-track trolley suspension conveyor. This structure is a type of electric hoist and accumulation-type suspension conveyor. The main functional components are: walking track, power transmission guide rail, turnout, rotating disc, elevator, running trolley , Spreader and control system. However, due to structural limitations, this transportation method can no longer meet the requirements of mass production, process level and quality on the automated transportation of heavy-duty wide bodies and large workpieces. The typical types are: ① The body of coaches has always been electrophoresed on the parts before body assembly, and then assembled. The result is not only low efficiency, but also the quality of the pretreatment electrophoresis damaged by the assembly connection and processing parts, and the final body paint quality is difficult to guarantee; ②The pre-processing technology of heavy truck frame adopts general lifting equipment, which not only has low level of process equipment, but also low production efficiency; ③The pre-processing of large structural parts of construction machinery also adopts electrophoresis of parts before assembly welding. Similarly, the quality of the electrophoresis process at the welding and joints cannot be guaranteed, especially for export products. The user's requirement must be overall electrophoresis, otherwise the product is judged to be unqualified.

The suspension rod 8 is a door-shaped pocket bottom structure. The ends are suspended on the two said conveyor chains.

The working principle of the above technical solution is:

When in use, the workpiece is first transported to the transition point of the incoming tower through the skid. At this time, a group of hanging spreaders that follow the movement of the conveyor chain lift the skid from below, so that the skid follows the movement of the hanging spreader and enters the lateral direction When it reaches the sinking position in the middle of the horizontal section, it enters the electric swimming pool for electrophoresis, and then follows the conveyor chain to enter the outlet tower and enter the transfer position. The skid and workpiece are transported out by the roller bed system, and the hanging spreader continues to follow the chain track Enter the second longitudinal section, and then continue to move into the horizontal support track. After entering the first longitudinal section, start the next cycle.

The beneficial effects of the above technical solution are: the vertical double-chain conveyor can meet the requirements of mass production, process level and quality on the overall automatic transportation of heavy-duty wide bodies and large workpieces, and has high working efficiency.
