Owing to having adopted the technical solution of the utility model, the utility model is under the cooperation of scraper finger and proximity transducer, cylinder, by the control of control circuit, only the scraper of stamp need to be placed on to the position of appointment, the selecting and pick and place all and can independently be completed by full-automatic machine people of scraper, save labour, improved automation efficiency.
The specific embodiment
With reference to Figure of description.The utility model comprises main supporting plate 3, be fixed on the arm terminal pad 11 on main supporting plate 3, be fixed on the cylinder 10 under main supporting plate, described cylinder is double acting stop cylinder, described cylinder 10 arranges the first air inlet pipe 31 and the second air inlet pipe 32, and respectively control cylinder bar 12 withdrawal and stretch out, described cylinder 10 belows arrange respectively two chutes in left and right, slide block is installed in chute, the cylinder rod 12 of cylinder 10 is connected with shift fork 4, one end of shift fork 4 connects the cylinder rod 12 of cylinder 10, the other end of shift fork 4 is connected with the slide block 9 in the chute of left and right respectively, on described slide block 9, connect scraper holding finger 5, main supporting plate 3 upper surfaces are also provided with the proximity transducer gripper shoe 1 vertical with main supporting plate 3, in proximity transducer gripper shoe 1, be equipped with proximity transducer 2, main supporting plate 3 is also equipped with proximity transducer trigger mechanism 8, on described proximity transducer trigger mechanism 8, cover has pin sheath 82, proximity transducer trigger mechanism 8 is arranged on through pin sheath 82 on the main supporting plate 3 of perforation and can be along the endoporus axially-movable of lever sheath 82, described proximity transducer trigger mechanism 8 comprises and is positioned at approaching piece 81 and approaching the bar portion 83 under piece of main supporting plate 3 tops, in described bar portion 83, be arranged with spring 7, approaching piece 81 moves upward and is triggered with proximity transducer 2 proximity transducer 2 when the same level line.
Described shift fork 4 comprises shift fork pawl 41, declutch shift shaft 42, and declutch shift shaft 42 is coaxially connected with cylinder rod 12 ends, and shift fork pawl 41 ends, both sides are connected with the inner of finger gripper shoe slide block 9.
Further, on described arm terminal pad 11, be provided with the terminals of control circuit and the jockey of gases at high pressure passage.Arm terminal pad 11 is to realize the key device that the arm of robot is communicated by letter with hand, has the terminals of control circuit and the jockey of gases at high pressure passage on arm terminal pad; Control circuit terminals are mainly for guaranteeing the arm of robot and the reliable and stable transmission of the signal of telecommunication between hand; The passage jockey of gases at high pressure is mainly used in to the needs to gases at high pressure when meeting finger movement of the cylinder conveying high-pressure gas in control box.After control circuit and gas circuit connection, when the signal of telecommunication being transmitted by mechanical arm arrives control box by arm terminal pad, control lower cylinder work at the signal of telecommunication, promotes cylinder rod motion, thereby the motion of cylinder rod is delivered to finger, realizes the action that clamps or loosen scraper.
With reference to Fig. 2, mechanical arm is driving scraper clamping device to move to doctor position, in the process to tram motion, proximity transducer pin 8 inserts scraper 100, in scraper 100, be provided with and be applicable to the special hole that insert on proximity transducer trigger mechanism 8 tops, after insertion, at the bottom of hole, withstood to the pin stroke of direction motion with scraper clamping mechanism kinematic opposite direction, proximity transducer 2 perceives the approaching approaching of piece 81 of proximity transducer trigger mechanism 8 and sends the signal of telecommunication, control circuit is controlled the first air inlet pipe 31 air inlets, cylinder 10 Work Promote cylinder rods 12 move upward.
With reference to Fig. 3, cylinder rod 12 cylinder stroke that moves upward, drive the declutch shift shaft 42 of shift fork 3 to move upward, the lower end C of shift fork 3 stirs finger gripper shoe slide block 6 and inwardly moves along guide rail, finger gripper shoe slide block 6 drive finger gripper shoes are inwardly moved, and scraper finger 5 inwardly moves and clamps scraper 100 in finger gripper shoe 4 chutes.
With reference to Fig. 3, when stamp finishes scraper 100 to replace, mechanical arm is transported to scraper to place on doctor position place placement doctor blade holder, scraper clamping device obtains the signal of " unclamping ", the second air inlet pipe 32 air inlets, cylinder 10 work, promote cylinder rod 12 and move downward a stroke, the declutch shift shaft 42 that cylinder rod 12 promotes shift fork 4 moves downward with cylinder rod 12, shift fork pawl 41 outwards moves, driving finger gripper shoe slide block 6 outwards to move, scraper finger 5 is outside motion " unclamping " scraper 100 thereupon.
Above embodiment is only for to illustrate of the present utility model, rather than restrictive.In the situation that not departing from the utility model claim institute protection domain, other variations or the modification made, all belong to protection domain of the present utility model.
