Description

Technical Field

[0001] The invention relates to an automated production line, in particular to a modular annular track device. Background Art

[0002] The existing technical solutions are mainly based on the ground circular rails of HepcoMotion in the UK. The technical implementation method is: install special V-shaped rollers on both sides of the slider, and then cooperate with the ground V-shaped guide rails; the V-shaped grooves on the rollers and the V-shaped grooves on the guide rails cooperate with each other to form a rolling guide structure, and the slider can slide under the guidance and support of the guide rails; the guide rails are of two types: conventional linear guide rails and specially optimized arc guide rails. The two guide rails can be combined to form a closed circular line; the closed circular line can be flexibly expanded by adding or removing replacement guide rails. Disadvantages of the existing technology: 1. The guide rail needs to be ground as a whole, and the V-shaped guide surfaces on both sides are difficult to process as a whole; especially for the arc guide rail, the trajectory of the transition connection section with the linear guide rail is not a standard circle, the processing technology is more complicated, and the processing difficulty is great; and in order to ensure the overall accuracy of the ring line, the interface positions of each guide rail section are all processed in pairs, and the interchangeability of the guide rails is poor; 2. The guide rail itself is not rigid, and the installation base surface is required to have sufficient accuracy to fix the guide rail without introducing new deviations due to the accuracy of the installation base surface itself. Therefore, the installation base surface must be machined; the accuracy requirements of the installation base surface increase the use cost of the ring line and also limit its scalability to a certain extent; 3. The existing ring line has high assembly requirements, and the installation and adjustment procedures are complicated, requiring installation workers to have sufficient training.

The slide rails 5 at each connection of these two connection methods are staggered, and the specific method is as follows Figure 7 As shown, the slide rails 5 at both ends of each straight guide rail module 1 or circular arc guide rail module 2 extend to the outside respectively. Since the length of each straight guide rail module 1 or circular arc guide rail module 2 is equal to the length of the slide rail 5 connected thereto, the slide rails 5 at both ends of each straight guide rail module 1 or circular arc guide rail module 2 extend to the outside respectively, and the other end will have the same length to be connected to the slide rail 5 on the connected straight guide rail module 1 or circular arc guide rail module 2.

Structural design of the guide rail module: the clamping design of the guide rail module does not require complicated grinding of the guide parts, thus reducing the processing cost of the module; at the same time, the structure makes the guide rail module itself more rigid, and the module itself is less sensitive to the dimensional accuracy of the base surface of the module installation, thereby reducing the accuracy requirements of the annular line installation base surface; this structure is applicable to both linear guide rail modules and circular arc guide rail modules, thereby greatly reducing the process cost on the circular arc guide rail module; 2. The movable design of the pin-shaft cooperation of the slider group: when the slider group enters the circular arc segment from the straight line or from the circular arc segment into the straight line segment, due to the two sets of sliders If the blocks enter in a certain order, there will be a group of sliders in the arc segment and a group of sliders in the straight segment. If the two sliders are rigidly connected, the sliders will be stuck in this case. Converting the rigid connection to a pin connection can avoid this problem; 3. Interface design between guide rail modules: The guide rail modules are teamed and matched, the interface surfaces of the main body profile and the fixed seat are staggered with the interface surfaces of the slide rails, and the slide rails act as positioning parts at the interfaces, which effectively reduces the matching requirements at the interfaces and also makes the transition between the slide rails smoother; and because the interface accuracy requirements are reduced, the interchangeability and scalability of the entire circular line are greatly enhanced, which is conducive to flexible transformation for on-site use.
