Electric brush feeding and inserting process: cutting the soft electric brush material belt into a strip shape matched with the height of the feeding box 1011, placing the strip shape into each strip cavity 10115 of the feeding box 1011, then placing the feeding box 1011 on the feeding box frame 1012 to enable the upper end of the first strip cavity to be aligned with the push head 10133 of the ejection mechanism 1013, then ejecting the soft electric brush in the first strip cavity from the feeding box 1011 by the ejection mechanism 1013 into the gap 1031 between the pressing plate 103 and the striker plate 102, and enabling a through hole on the soft electric brush to correspond to the longitudinal strip groove 1032 on the pressing plate 103; then, the stepping pulling driving device 104 drives the puncture needle 106 to penetrate through a through hole on the soft electric brush through operations of lifting, translation and the like, and the soft electric brush material belt is pulled down step by step, so that the soft electric brush corresponds to the position of the clamping device 105; then the clamping device 105 controls the clamping jaw 1054 to tear the soft electric brush from the material belt and send the soft electric brush to an electric brush caulking groove at a specified position through operations such as lifting, translation and the like, and then the next procedure is carried out; after the feeding of all brushes is accomplished to a whole strip soft brush material area, feed box translation mechanism 1014 control translation, pull out and insert bar inserted block 10141, cooperate with bar jack 10116 through bar inserted block 10141, chimb 10111 and direction spout 10121 cooperate to drive feed box 1011 and carry out the translation on feed box frame 1012, make next strip cavity aim at push head 10133, in the clearance 1031 between the soft brush area top clamp plate 103 and striker plate 102 in the next strip cavity, carry out the feeding in next strip soft brush material area.
End cover feeding process: the end covers are arranged in order through a vibrating disc, are sent into a conveying rail 301 through upstream related equipment, and are conveyed in a poking mode through a poking mechanism 302; when the end cover is conveyed to the end cover rotating device of the left operation port 3031, the rotating cylinder of the left operation port 3031 drives the end cover rotating seat to rotate leftwards, the left electric brush feeding device 1 conveys the soft electric brush to a corresponding electric brush caulking groove on the end cover and is pressed by the left pressing mechanism 4, then the rotating cylinder of the left operation port 3031 enables the end cover rotating seat to reset, and the toggle mechanism 302 continues to toggle and convey the end cover; similarly, when the end cover is sent to the end cover rotating device of the right operation port 3032, the rotating cylinder of the right operation port 3032 drives the end cover rotating base to rotate to the right, the right brush feeding device 2 sends the soft brush to the corresponding brush caulking groove on the end cover, the soft brush is pressed by the right pressing mechanism 5, then the rotating cylinder of the right operation port 3032 enables the end cover rotating base to reset, and the toggle mechanism 302 sends out the end cover with the soft brushes inserted into two sides.
In conclusion, the full-automatic soft electric brush inserting machine enables the soft electric brush which is bent in advance according to the electric brush caulking groove shape of the end cover of the micro motor to be positioned in the strip-shaped cavity 10115 of the feeding box 1011; when the feeding is not carried out, the soft electric brush which is bent in advance according to the shape of the electric brush caulking groove of the end cover of the micromotor is positioned in the strip-shaped cavity 10115 of the feeding box 1011 and limited by the strip-shaped cavity 10115; when the ejection mechanism 1013 ejects the soft electric brush from top to bottom from the strip-shaped cavity 10115 into the gap between the striker plate 102 and the pressing plate 103, the soft electric brush material belt is only subjected to the thrust from the ejection mechanism 1013 from top to bottom and is not influenced by external force in other directions; when the soft electric brush material belt is pulled in a stepping mode and clamped and fed, the soft electric brush material belt is limited by the striker plate 102 and the pressing plate 103; therefore, the soft electric brush can be prevented from deforming in the feeding process of the whole soft electric brush, the full-automatic and accurate insertion of the soft electric brush into the electric brush caulking groove is realized, and the production efficiency is improved.
In addition, it should be noted that the names of the parts and the like of the embodiments described in the present specification may be different, and the equivalent or simple change of the structure, the characteristics and the principle described in the present patent idea is included in the protection scope of the present patent. Various modifications, additions and substitutions for the specific embodiments described may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
