Ballpoint pen refill automatic scratch inspection equipment

Abstract

The invention relates to a ball point pen refill automatic marking inspection device. The ball point pen refill automatic marking inspection device is characterized in that multiple axially same crankshafts not disposed in the same plane are utilized, one of these crankshafts is an driving crankshaft, the driving crankshaft drives a pen refill in a marking unit to perform circle drawing motion, at the same time, the marking unit drives other driven crankshafts to rotate synchronously, and the pen refill in the marking unit is enabled to maintain at a stable state in the circle drawing process, such that the pen refill can be prevented from damage, ink in an ink tube of the pen refill can also be prevented from being interrupted, and secondary quality accidents are avoided. During operation, a paper delivery wheel of a paper feeding unit rotates to drive paper to move, the marking unit drives the pen refill to draw a locus on the paper, an image acquisition unit acquires the locus, a master control unit, according to an image, determines whether line breaking, hollowing or single siding occur in the pen refill, and if the line breaking, the hollowing or the single siding are detected, the master control unit controls a rejection apparatus to reject the corresponding pen refill.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a detection device for detecting ballpoint pen cores. Background technique [0002] Ballpoint pens (refills) currently occupy most of the market for writing products. The ballpoint pen refills produced by the factory need to be tested for writing performance before leaving the factory. The main purpose is to determine whether the product has writing defects such as unilateral, hollow and broken lines. Defective products need to be picked out and cannot be inflowed. market sale. At present, domestic stationery manufacturers produce more than 10 billion ballpoint pen refills every year, most of which are selected by manual inspection. Quality brings additional risks. Patent CN201110315436 discloses a pen refill marking inspection device, which is used for automatic marking and inspection of assembly line pen refills.

At present, domestic stationery manufacturers produce more than 10 billion ballpoint pen refills every year, most of which are selected by manual inspection. Quality brings additional risk

Patent CN201110315436 discloses a pen refill marking inspection device, which is used for automatic marking and inspection of assembly line pen refills. By trying to use the product of this patent, the following problems have occurred: 1. The existing production line station for pen refills is determined, and it is very difficult to There is little space for installation; 2. The eccentric discs of the circle drawing part of this product are arranged in a plane. When the product draws a circle quickly, there will be vibration in the circle drawing part, which will reduce the reproducibility of the circle drawing stitches.

The tip of the ballpoint pen core is small, and the ink in the ink storage tube is fluid, especially the neutral pen core. The ink has thixotropy, and its viscosity is sensitive to vibration. The transfer of the pen core must be as gentle as possible during the marking inspection process of the machine marking device to avoid rushing. The start and stop movement of the pen core will generate knocking vibration, otherwise it will easily lead to damage to the pen tip or disconnection of the ink column in the ink storage tube, resulting in secondary quality accidents of the pen core. The current products in use are limited in use due to this defect.
