Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] Referring to Figures 1 to 3 , a rotary mechanical gripper for grabbing a marker pen provided by the present invention includes a U-shaped seat 1. A conveying mechanism is arranged in the U-shaped seat 1. A plurality of notches 4 are formed on the top surface of the U-shaped seat 1. A cylinder 17 is vertically fixed to the rear side of the middle section of the U-shaped seat 1. The top surface of the cylinder 17 is fixedly connected to a top plate 12. A second mounting plate 13 is arranged on the top surface of the top plate 12. A rotary motor 18 is vertically fixed to the top surface of the second mounting plate 13. The output end of the rotary motor 18 is drivingly connected to a rotating shaft 22. An air cavity 28 is axially formed on the bottom surface of the rotating shaft 22. A horizontally connected intake pipe 27 communicating with the air cavity 28 is arranged on the outer side of the rotating shaft 22. A correcting member is arranged on the U-shaped seat 1. An arc surface 29 is arranged at the end of the rotating shaft 22. The correcting member includes a second support plate fixed to the top surface of the U-shaped seat 1. A third mounting plate is arranged on the top surface of the second support plate. A position sensor 21 is fixedly connected to the end of the third mounting plate;
[0020] The conveying mechanism includes two driving shafts 25 horizontally and rotatably connected to both sides of the inner wall of the U-shaped seat 1. A sprocket 26 is fixedly sleeved on each side of each driving shaft 25. A chain 3 is commonly sleeved between the two sprockets 26 on the same side. A plurality of equally spaced conveyor rollers 2 are horizontally and fixedly fixed between the two chains 3. A driving motor 24 is horizontally fixed to the outside of the U-shaped seat 1. The driving motor 24 is drivingly connected to the end of one of the driving shafts 25;
[0021] Referring to Figures 1 to 3, in order to monitor the lack of materials and empty materials on the conveying mechanism, a third support plate is horizontally fixed outside the U-shaped seat 1. A fourth mounting plate is provided on the top surface of the third support plate, and a second infrared sensor 10 is fixedly connected to the end of the fourth mounting plate. A first electric push rod 19 is horizontally fixed in the notch 4 between the second support plate and the third support plate;
[0022] Referring to Figures 1 to 3 , for the purpose of preventing foreign objects from getting stuck on the conveying mechanism and removing the pen bodies that fail to be turned over from the conveying mechanism, a first support plate 6 is fixedly connected to the outside of the U-shaped seat 1. A first mounting plate 9 is provided on the top surface of the first support plate 6, and a first infrared sensor 20 is fixedly connected to the end of the first mounting plate 9. A second electric push rod 11 is horizontally fixed in the notch 4 on the same side as the first infrared sensor 20, and a third electric push rod 23 is horizontally fixed in the notch 4 on the opposite side;
[0023] Referring to Figures 1 to 3 , in order to turn over pen bodies of different lengths, a first long circular hole 5 vertically penetrates through the top surface of the first mounting plate 9. A first stud 8 is movably inserted through the first long circular hole 5. The first stud 8 is vertically fixed on the top surface of the first support plate 6. A first nut 7 is threadedly sleeved on the outer edge of the first stud 8, and the first nut 7 abuts against the top surface of the first mounting plate 9. A second long circular hole 16 vertically penetrates through the top surface of the second mounting plate 13. A second stud 14 is movably inserted through the second long circular hole 16. The second stud 14 is vertically fixed on the top surface of the top plate 12. A second nut 15 is threadedly sleeved on the outer edge of the second stud 14, and the second nut 15 abuts against the top surface of the second mounting plate 13.
[0024] By providing a correcting member and a rotating shaft 22 with an air cavity 28 on the U-shaped seat 1, it plays an automatic straightening role for the pen bodies that are not properly positioned on the conveying mechanism without the need to manually straighten the pen bodies, thereby saving the human resource cost.
[0025] Working principle: During use, the pen body enters the U-shaped seat 1 from the right side of the conveying mechanism. When the first infrared sensor fails to detect the pen body, a warning will be issued. When it is detected, no warning will be given. At the same time, the first electric push rod 19 will perform continuous reciprocating displacement, so that the first electric push rod 19 will push the pen body placed upside down to the other side of the U-shaped seat 1 by pushing the tip of the pen, increasing the space for the pen body to flip. Then the pen body will move below the position sensor 21. When the position sensor 21 cannot detect the position of the pen tip, it means that the pen body is placed upside down. The upside-down pen body will move below the rotating shaft 22. The air pipe drives the rotating shaft 22 to descend, so that the end of the rotating shaft 22 abuts against the outside of the pen body. Then the air pipe connected to the air supply system sucks out the gas in the air chamber 28, and adsorbs and fixes the pen body at the end of the rotating shaft 22 through negative pressure. Then the cylinder 17 drives the rotating shaft 22 to rise, and then the rotating motor 18 drives the rotating shaft 22 and the pen body to rotate 180 degrees. After the pen body is placed upright, the pen body is placed back on the conveying mechanism. Then the air pressure is turned off, and the rotating shaft 22 is separated from the pen body. The second electric push rod 11 performs continuous reciprocating displacement, and ejects the non-flipped pen body out of the conveying mechanism through the opposite notch 4. At the same time, when the first infrared sensor 20 detects an item at the empty material position on the conveying mechanism, the third electric push rod 23 ejects it out of the conveying mechanism through the opposite notch 4.
[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
