Description

Paper core dispensing pre-clamping device

Technical Field

The invention belongs to the technical field of mechanical and electrical control, and particularly relates to a paper core dispensing and pre-clamping device.

Background

The existing paper core dispensing and bonding process is to dispense a certain amount of AB glue on a circular groove of an end cover and then convey the glue to a bonding position to wait for bonding with a paper core. However, in the actual production process, the cylindrical filter paper core is in a corrugated state, and becomes loose and larger in outer contour size under the condition of no external force, and the size of the end cover is smaller. And the upper part of the filter paper core on the placing hole site is clamped by the manipulator, then the clamped paper core is taken out and further conveyed to the end cover on the bonding position, and is aligned with the end cover to be put down, so that bonding is realized, and the paper core is clamped and conveyed away by the manipulator after bonding is finished. The size of the paper core clamped by the mechanical arm is slightly smaller than the ring groove on the end cover. Meanwhile, in order to improve the production efficiency and meet the requirement of batch production, the manipulator is required to grab, convey and bond more than seven paper cores at one time. In addition, in the process of grabbing the workpiece by the manipulator, the manipulator needs to continuously reciprocate and is not suitable for continuously placing the workpiece on a working station, so that the paper core placing bedplate is designed, namely the paper core grabbing is not carried out in the paper core placing process. In order to avoid the influence on the production progress caused by frequent installation of paper cores by workers, the operators need to install more paper cores on the limited paper core placing bedplate as much as possible. The paper core placing bedplate is in a square body, 10 rows of paper cores can be placed in sequence, and 7 paper cores in each row can be placed in sequence, so that 70 placing hole positions are required to be designed on the paper core placing bedplate.

However, the outline of the loose paper core is indefinite, and when the mechanical arm grabs the loose paper core, the clamping jaw needs to be opened to a larger size, so that the loose paper core can be extruded to the paper core on the hole position beside the station for grabbing the paper core, and even the loose paper core is crushed. If the mounting hole sites are made smaller, the paper cores are slightly held tightly when being placed in the placing hole sites, which can slow down the placing progress of workers, and the time for placing the paper cores can be greatly prolonged, thereby affecting the efficiency. Therefore, the designed paper core placing bedplate has the function of meeting the requirement that workers can place 70 loose paper cores quickly, so that the workers can take out the paper cores from the box for storing the paper cores and put the paper cores into the box quickly; and the jaws of the robot are not opened so much that the open jaws do not exceed the limited space between adjacent cores.
