Description

A 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 pre-clamping device.

Background technique

The existing paper core dispensing and bonding process is to first point a certain amount of AB glue on the annular groove of the end cover, and then transfer it to the bonding position to wait for bonding with the paper core. However, in the actual production process, the cylindrical filter paper core is in a wrinkled state. Under the action of no external force, it is loose and becomes larger in size, and the size of the end cap is smaller. And clamp the upper part of the filter paper core on the hole position by the manipulator, then take out the clamped paper core, further transport it to the end cover on the bonding position, and put it down at the end cover to realize bonding and bonding. After completion, it is clamped and transported away by the manipulator. The size of the paper core after being clamped by the robot is slightly smaller than the ring groove on the end cover. At the same time, in order to improve production efficiency and meet the requirements of mass production, the manipulator is required to grab, transport and bond more than seven paper cores at a time. In addition, in the process of grasping the workpiece by the manipulator, continuous reciprocating motion is required, which is not suitable for placing the workpiece continuously on the working station. Therefore, the paper core placement platen is designed, that is, the paper core is not grasped during the paper core placement process. . In order to prevent workers from frequently installing paper cores and affecting the production progress, the operators should try to install as many paper cores as possible on the limited paper core placement table at one time. The paper core placement platen is in a square shape, and a total of 70 paper cores can be placed in 10 rows, 7 in each row, so it is necessary to design 70 placement holes on the paper core placement platen.

However, the size of the outer contour of the loose paper core is not fixed. When the manipulator grasps, its jaws need to be opened to a larger size, which will squeeze the hole on the side of the station to be grasped. paper core, or even crush it. If the installation hole is made smaller, when the paper core is placed in the installation hole, it will be in a slightly tight state, which will slow down the placement progress of workers, and cause the time for placing the paper core to be greatly prolonged, affecting the efficiency. Therefore, the function of the designed paper core placement platen is to not only meet the requirements of workers to quickly place 70 loose paper cores, so that workers can quickly take out and put in the paper cores from the box where the paper cores are stored; The clamping jaws should not be opened too much, so that the opened jaws should not exceed the limited space between adjacent paper cores.
