Description

Technical Field

[0001] The utility model relates to the technical field of double-speed conveying lines, in particular to a vacuum conveying device. Background Art

[0002] The double-speed conveyor line is also called the double-speed chain, double-speed conveyor chain, or differential chain line. It is a self-flowing assembly line equipment widely used in the production lines of the electronic and electrical industry, playing an important role in improving production efficiency and reducing production costs.

[0003] For example, a conveyor line for a manipulator with application number CN201610700297.1 and publication date 20161130 includes a support platform, a conveyor belt provided on the surface of the support platform, the conveyor belt connected to a motor via a belt drive device, the conveyor belt including a plurality of rollers, a plurality of lifting mechanisms provided below the conveyor belt, a plurality of top plates provided on top of the lifting mechanisms, the top plates provided between two adjacent rollers, the top plates provided along the axial direction of the rollers, a clamping plate provided on each end of the conveyor belt, a plurality of roller avoidance holes provided on the surface of the clamping plate, and the clamping plate connected to a thrust cylinder. The present invention has a reasonable design, a compact structure, a positioning and shaping effect, and is convenient for grasping.

[0004] For example, a vacuum adsorption carrier module with application number CN202120280901.6 and authorization announcement number 20211105 is fixedly connected to the outer shell through several first connecting blocks, several suction cups are fixedly connected to the other side of the several first connecting blocks, several plastic parts are fixedly connected to the several suction cups, the plastic parts have several suction holes, two second connecting blocks are fixedly connected to the outer shell, two valve bodies are fixedly connected to the two second connecting blocks, two valve cores are fixedly connected to the two second connecting blocks, two limit blocks are fixedly connected to the two valve cores, two retaining spring baffles are fixedly connected to the two valve bodies, and two springs are fixedly connected to the two retaining spring baffles. When the battery core is sucked, the skirt of the suction cup contacts the battery core. Due to the action of suction, the battery core slowly drops and contacts the plastic part, which increases the contact area between the suction cup and the battery core, reduces the pressure of the suction cup on the battery core, and solves the problem that the vacuum adsorption carrier module is easily damaged during clamping.

[0005] At present, double-speed conveyor lines use carriers to transport products. Traditional carriers include mechanical clamping conveying carriers and short-time vacuum adsorption carriers. Mechanical clamping conveying carriers cannot transport products with high positioning accuracy and easy deformation, and the spring clamping mechanism can easily damage the products; while short-time vacuum adsorption carriers have a small cavity volume and a short adsorption time (the stop valve and pipeline cannot guarantee long-term sealing, and vacuum leakage will occur after a period of time), which cannot meet the requirements of long-distance and long-term transportation, and there is a greater risk of releasing products due to unstable negative pressure during transportation. Therefore, it is urgent to design a vacuum conveying device to solve the above problems. Utility Model Content
