Description
Technical Field
The invention relates to a track trolley assembly line.
Background
The assembly line is a professional production line which is customized according to the production characteristics of customers and the process requirements of the customers, and is used for meeting the production requirements of the customers.
The speed doubling chain line is widely used in an assembly line because the technology is mature. The speed-multiplying chain line is mainly used for conveying materials in an assembly and processing production line, and the tooling plate for bearing cargos on the chain line can run quickly through the speed-increasing function of the speed-multiplying chain line and is stopped at a corresponding operation position through the stopper. Meanwhile, the tooling plates can be stacked and conveyed, and due to the stacking function of the tooling plates, one conveying line is driven by one power and is divided into a fixed number of assembly stations according to the current technological requirements.
However, with social progress, market competition is intensified, and the demand of terminal consumers is higher and higher, so that the upgrading and updating of products are faster and faster, and the product period is shorter and shorter. In response to this challenge, manufacturers are continually modifying the process sequence and tuning the production line. When a manufacturer adjusts a production line, the original production line is fixed in structural design, so that the situation of small size and material consumption (if the original eight stations are adjusted to six stations, two more stations cause waste) is caused, and waste is caused; or equipment is added (for example, the original six stations are increased to eight stations, or a two-station conveyor is added behind the original production line, or the original production line is cut, so that the length of a frame and a speed doubling chain is increased), and the cost pressure is increased. The more flexible the design comes to the customer's weight.
The AGV dolly can directly constitute flexible assembly line as a part of intelligent factory. For example, five stations are designed, five AGV trolleys are directly used, the trolleys circularly move according to a design route to form an assembly line, and when the stations need to be adjusted, the AGV trolleys are directly increased or decreased. However, the assembly line of AGV carts suffers from the following problems:
1. energy source bottleneck: a power source of the AGV trolley is powered by a storage battery, and the power must be supplemented when the AGV trolley is used for a certain time. The following three charging methods are commonly used:
A. offline charging: charging needs a certain time, and in order to ensure production, in particular to a 24H factory, an AGV with the input multiple of the number of stations is needed;
B. replacing the battery pack on line: the same as a, and a sufficient number of battery packs need to be secured;
C. wireless charging: a special power system is required while considering the tact time of each station of the assembly line, and the shorter the time, the more wireless charging stations need to be arranged.
2. The problem of efficiency: because the AGV trolley does not need a special track to directly move on the ground, the AGV trolley needs to be designed into a loop line according to the section of beat requirement of the assembly line unloading and the assembly line on-line. If the annular is smaller, the space in the middle of the annular is difficult to use, and if the annular inner space is designed to be used as space, when people or objects pass through the inside and the outside of the annular, the AGV trolley can be unnecessarily stopped due to the safety arrangement of the AGV trolley.
The design of the AGV cart directly into the assembly line is therefore very disadvantageous.
