The invention discloses a longitudinal four-axis multistation coil aftertreatment adhesive dispensing, line arranging and tin adhering mechanism. The mechanism comprises a four-index coil loading mechanism, a coil wound on the four-index coil loading mechanism and an unloading mechanism; the four-index coil loading mechanism comprises an X direction arranged motor, and a rotary table driven to rotate by virtue of the motor and four winding components which are arranged on the rotary table along the radial direction at intervals of 90 degrees. The longitudinal four-axis multistation coil aftertreatment adhesive dispensing, line arranging and tin adhering mechanism also comprises an adhesive dispensing mechanism arranged at a horizontal position I, a line arranging mechanism which can arrange skintles, arranged just above, of the coil and a tin adhering mechanism, the unloading mechanism is arranged below the four-index coil loading mechanism, a compression bar driving device can drive the front end of a compression bar to be inserted into the two sides of a groove of a sliding sleeve of the winding component arranged below and then move down in z direction, and the compression bar moves down to push the sliding sleeve, located at the coil, of the winding component to the tail end of a winding shaft. The mechanism disclosed by the invention is convenient for loading of the coil, line arranging, avoidance of offset of roots of the skintles during the line arranging, tin adhering and unloading.
