[0017] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0018] A high-precision nut automatic implanting device includes an industrial robot manipulator 1, a mounting plate 11 detachably connected to the front end of the industrial robot manipulator 1, and a guide plate 12 fixedly connected to the front side surface of the mounting plate 11. A machine base 2 is slidably connected to the surface of the guide plate 12. A support plate 21 is detachably connected to the inner side of the bottom of the machine base 2. Four groups of connecting columns 22 are detachably connected to the upper surface of the support plate 21. The bottom ends of the connecting columns 22 penetrate through the support plate 21 and are detachably connected to an execution plate 23. A transportation mechanism 3 for inputting and outputting nuts is arranged on the top of the execution plate 23. A conveyor channel 24 is opened inside the execution plate 23. A pushing mechanism 4 for pushing the nut to move in the conveyor channel 24 is arranged on the front side inside the conveyor channel 24. A branch channel 25 is opened inside the execution plate 23 at the left side of the tail of the conveyor channel 24. An auxiliary mechanism 7 for pushing the nut into the branch channel 25 is arranged on the rear side inside the conveyor channel 24. A pretreatment mechanism 8 for cleaning and preheating the nut is arranged inside the conveyor channel 24 between the pushing mechanism 4 and the auxiliary mechanism 7.

[0019] As Figure 1As shown in the figure, the mounting plate 11 is detachably connected to the front end of the industrial robot manipulator 1. The industrial robot manipulator 1 is equipped with a corresponding control panel. During operation, the industrial robot manipulator 1 can drive the mounting plate 11 to move in various directions, facilitating the alignment of the nut with the hole position on the workpiece and improving the assembly accuracy. A corresponding drive source is provided on the mounting plate 11, and the drive source can drive the base 2 to move up and down along the guide plate 12 on the surface of the mounting plate 11. The support plate 21 is detachably connected to the execution plate 23 through four sets of connecting columns 22. The rear side of the support plate 21 is fixedly connected to the inner side of the bottom of the base 2, so the support plate 21 can move synchronously with the base 2. Among them, the execution plate 23 is a splicing structure and can be divided into two parts with the axis as the boundary. The two parts are detachably connected, such as by screw connection, which is convenient for cleaning and repairing the inside of the execution plate 23.

[0020] As Figures 1 - 7 shown in the figure, the transportation mechanism 3 on the industrial robot manipulator 1 is used for inputting and outputting nuts. Among them, the transportation mechanism 3 includes a feeding channel 31 and a discharging channel 33 opened on the upper surface of the base 2. The feeding channel 31 and the discharging channel 33 are not in the same straight line. The bottom end of the feeding channel 31 penetrates the base 2, the support plate 21 and the execution plate 23 and extends into the conveying channel 24. Among them, the external material bin is connected to the feeding channel 31 through a conveying pipeline 32, and is equipped with relevant gas sources, ejectors, air valves, etc. With the help of negative pressure, the nuts are sucked out of the material bin and sent into the conveying pipeline 32. Then, under the push of the air flow, the nuts are transported to the designated position. As Figure 3 shown and as Figure 7 shown in the figure, the bottom end of the discharging channel 33 penetrates the base 2, the support plate 21, the execution plate 23 and the branch channel 25 and extends to the outside of the bottom surface of the execution plate 23. A guiding cylinder 35 is detachably connected to the bottom port of the discharging channel 33. The branch channel 25 is communicated with the conveying channel 24. A telescopic cylinder 34 is installed on the top of the base 2. The piston rod of the telescopic cylinder 34 extends into the discharging channel 33. When the nut moves along the conveying channel 24 and the branch channel 25 into the discharging channel 33, at this time, the base 2 drives the bottom end of the guiding cylinder 35 to correspond to the working hole position. The telescopic cylinder 34 is started and the piston rod pushes the nut to move downward, and moves along the inner wall of the guiding cylinder 35 into the workpiece hole position. And the end of the piston rod of the existing telescopic cylinder 34 is also provided with a heating effect, so that the nut is hot-melt installed inside the hole position. As Figures 3 - 6As shown in the figure, the pushing mechanism 4 on the robotic arm 1 of the industrial robot is used to push the nut to move inside the conveying channel 24. The pushing mechanism 4 includes a moving plate 41 slidably connected inside the conveying channel 24. The front end of the moving plate 41 is detachably connected to the movable plate 42. The movable plate 42 is connected to the piston rod of the movable cylinder 44 through the connecting plate 43. When the movable cylinder 44 is started, the connecting plate 43 drives the moving plate 41 to move inside the conveying channel 24 through the movable plate 42. A positioning groove 45 is formed on the surface of the moving plate 41. Initially, the positioning groove 45 is located at the bottom of the feeding channel 31. The positioning groove 45 penetrates the upper and lower surfaces of the moving plate 41 and a positioning rod 46 is slidably connected inside. The bottom of the positioning rod 46 contacts the bottom surface of the conveying channel 24. It should be noted that the rear side of the bottom of the feeding channel 31 is open. At this time, the top of the positioning rod 46 extends into the bottom of the feeding channel 31, so that the nut can be smoothly sleeved on the outer circumferential side of the positioning rod 46 after detaching from the conveying pipe 32; As Figures 4 - 5 shown in the figure, the moving plate 41 drives the nut to move inside the conveying channel 24 through the positioning rod 46. A disc 47 is fixedly connected to the top surface of the positioning rod 46. The limiting groove 5 is formed on the top surface of the conveying channel 24 and is located behind the feeding channel 31. The rear side opening at the bottom of the feeding channel 31 is communicated with the limiting groove 5, and the disc 47 at the top of the positioning rod 46 can slide into the limiting groove 5 through this opening. The moving plate 41 limits the bottom of the positioning rod 46, and the limiting groove 5 limits the top of the positioning rod 46 through the disc 47, which is convenient for improving the stability of the nut movement; As Figures 3 - 6 shown in the figure, a circular groove 51 is formed on the bottom surface of the limiting groove 5 at the connection between the branch channel 25 and the conveying channel 24. When the nut moves to the connection between the branch channel 25 and the conveying channel 24, the diameter of the disc 47 is smaller than the diameter of the circular groove 51. Under the action of the self-gravity of the positioning rod 46, the disc 47 disengages from the limiting groove 5. And a moving groove 54 is formed on the bottom surface of the conveying channel 24 below the limiting groove 5. The bottom surface of the moving groove 54 is set as an inclined surface, and the inclined direction is downward from the feeding channel 31 to the limiting groove 5. Therefore, the positioning rod 46 and the disc 47 also disengage from the nut, and the bottom end of the positioning rod 46 extends into the moving groove 54; As Figure 6 shown in the figure, a placing groove 52 is formed on the upper surface of the moving plate 41 at the top surface of the positioning groove 45. The placing groove 52 and the positioning groove 45 are concentric circles. The diameter of the disc 47 is larger than the diameter of the placing groove 52. The disc 47 is embedded inside the placing groove 52 and the upper surface of the disc 47 is flush with the upper surface of the moving plate 41. A ball 53 is rotatably connected to the bottom surface of the positioning rod 46. The positioning rod 46 contacts the bottom surface of the moving groove 54 through the ball 53. The ball 53 improves the smoothness of the movement of the positioning rod 46; As Figures 3 - 5As shown, when the moving plate 41 resets, the moving plate 41 drives the positioning rod 46 to move through the positioning groove 45. The positioning rod 46 moves along the inclined bottom surface of the moving groove 54 with the help of the ball 53. The disc 47 disengages from the placement groove 52 and the top of the positioning rod 46 gradually moves upward relatively until the positioning rod 46 moves to the initial position.

[0021] A magnetic sheet can also be installed inside the actuator plate 23 below the circular groove 51. The magnetic sheet is specifically located on the front side of the branch channel 25. When the nut moves below the circular groove 51, the outer cylindrical surface of the nut will contact the magnetic sheet, and the magnetic sheet adsorbs the nut, thereby reducing the situation where the nut shifts on the upper surface of the moving plate 41 when the moving plate 41 resets.

[0022] As Figure 8 shown, the auxiliary mechanism 7 on the industrial robot manipulator 1 is used to assist in pushing the nut into the branch channel 25. The auxiliary mechanism 7 includes an auxiliary space 71 opened on the side wall at the end of the conveying channel 24. The auxiliary space 71 and the branch channel 25 are on opposite sides. A lower gear 72 is rotatably connected to the bottom surface of the auxiliary space 71. A lower rack 73 is fixedly connected to the right side surface of the moving plate 41. The lower gear 72 is engaged with the lower rack 73. When the moving plate 41 moves, the moving plate 41 can drive the lower gear 72 to rotate inside the auxiliary space 71 through the lower rack 73; As Figure 6 and Figure 8 shown, at the same time, an upper gear 74 is fixedly connected to the top of the rotating rod of the lower gear 72. The lower gear 72 can drive the upper gear 74 to rotate synchronously inside the auxiliary space 71. A push plate 75 is slidably connected to the top surface of the auxiliary space 71. A notch is formed on the surface of the push plate 75 and an upper rack 76 is fixedly connected to the side wall of the notch. The upper rack 76 is engaged with the upper gear 74. The upper gear 74 can drive the push plate 75 to slide on the top surface of the auxiliary space 71 through the upper rack 76. A limiting plate 77 is fixedly connected to the front end of the push plate 75. If the moving plate 41 drives the nut to move towards the port of the branch channel 25, at this time the push plate 75 drives the limiting plate 77 to move towards the auxiliary space 71. On the contrary, if the moving plate 41 resets, at this time the push plate 75 drives the limiting plate 77 to move towards the inside of the branch channel 25, thereby pushing the nut into the branch channel 25 with the limiting plate 77.

[0023] As Figure 7As shown, at the connection between the branch channel 25 and the discharge channel 33, an installation ring 6 is detachably connected to the inner side of the discharge channel 33. A plurality of flat plates 61 are rotatably connected to the outer circular surface of the installation ring 6, and a torsion spring is arranged at the rotation position. Initially, the upper surface of the flat plates 61 is flush with the upper surface of the branch channel 25. The plurality of flat plates 61 support the nuts, enabling the nuts to move smoothly into the discharge channel 33. During operation, the piston rod of the telescopic cylinder 34 presses the plurality of flat plates 61 through the nuts, and the flat plates 61 turn downward, causing the nuts to move into the guiding cylinder 35. A plurality of notches are formed in the inner wall of the discharge channel 33, corresponding to the flat plates 61. The flat plates 61 can be embedded into the notches when they turn, so as to keep the inner wall of the discharge channel 33 flat and not affect the movement of the nuts inside the discharge channel 33.

[0024] As Figures 4 - 5 shown, the pretreatment mechanism 8 on the robotic arm 1 of the industrial robot can clean the surface of the nuts and preheat the nuts. The pretreatment mechanism 8 includes two cleaning plates 81 detachably connected to the side wall of the conveying channel 24. The two cleaning plates 81 are symmetrically arranged, and silica gel sponges are installed inside the cleaning plates 81. The cleaning plates 81 are arranged on one side of the conveying channel 24 close to the bottom end of the feeding channel 31. The moving plate 41 drives the nuts to move through the positioning rod 46, enabling the nuts to pass through the two cleaning plates 81. Thus, the silica gel sponges inside the cleaning plates 81 clean the surfaces of the nuts. After the nuts pass through the cleaning plates 81, the heating wires inside the positioning rod 46 are activated. The heating wires generate heat and preheat the nuts, thereby reducing the influence of impurities on the firmness of the nuts inside the hole positions and accelerating the nut assembly efficiency.

[0025] As Figure 5 shown, a cavity 82 is formed inside the moving plate 41. The bottom surface of the cavity 82 is open, and a plurality of tooth blocks are fixedly connected to the bottom of the positioning rod 46 inside the cavity 82. The L-shaped plate 83 is arranged on the left side of the limiting groove 5 and is detachably connected to the bottom surface of the conveying channel 24. At the same time, a plurality of tooth grooves are fixedly connected to the top end of the L-shaped plate 83. The top of the L-shaped plate 83 extends into the cavity 82, and the tooth blocks are engaged with the tooth grooves. When the moving plate 41 moves, the L-shaped plate 83 moves relative to the moving plate 41 along the opening of the bottom surface of the cavity 82. Through the engagement of the tooth blocks and the tooth grooves, the positioning rod 46 rotates along the L-shaped plate 83. A vertical concave-convex surface is arranged on the outer circular surface of the positioning rod 46 between the positioning rod 46 and the nut, increasing the friction force between the positioning rod 46 and the nut. Thus, the positioning rod 46 drives the nut to rotate on the upper surface of the moving plate 41, and the cleaning plates 81 clean the nuts from multiple angles, facilitating the improvement of the cleaning effect of the cleaning plates 81. At the same time, the wires of the heating wires extend into the positioning rod 46 from the axis of the bottom end of the positioning rod 46, and the bottom end of the positioning rod 46 is rotatably connected to the rest of the positioning rod 46, thereby reducing the situation of the wires being wound as the positioning rod 46 rotates.

[0026] It should be noted that the present invention is a high-precision nut automatic implanting device. As Figures 1 - 8 shown, first, before the nut is implanted and moved by the industrial robot, the position of the mounting plate 11 and the position of the base 2 on the mounting plate 11 are adjusted under the cooperation of the robotic arm 1 of the industrial robot and the driving source, so that the bottom end of the guiding cylinder 35 corresponds to the workpiece hole position; Then, under the cooperation of the air source, the injector and the air valve, the nut is sucked out from the external storage bin and sent into the interior of the conveying pipeline 32. Then, under the push of the air flow, the nut disengages from the feeding channel 31 and lands on the positioning rod 46. The movable cylinder 44 is activated, and the movable rod of the movable cylinder 44 drives the connecting plate 43 to move, so that the connecting plate 43 drives the moving plate 41 to move inside the conveying channel 24 through the movable plate 42, so that the moving plate 41 drives the nut to move towards the branch channel 25 through the positioning rod 46. During this process, the silica gel sponge inside the cleaning plate 81 first cleans the nut, and then preheats the nut through the heating wire inside the positioning rod 46. At the same time, the moving plate 41 moves inside the limiting groove 5 through the disc 47. When the nut moves below the circular groove 51, the disc 47 disengages from the limiting groove 5 and is located inside the placement groove 52, and the bottom of the positioning rod 46 contacts the bottom surface of the moving groove 54. At this time, the positioning rod 46 disengages from the nut; Then the moving plate 41 resets and the moving plate 41 drives the lower gear 72 to rotate through the lower rack 73. The lower gear 72 can drive the upper gear 74 to rotate, so that the upper gear 74 can drive the push plate 75 to slide through the upper rack 76, so that the limiting plate 77 pushes the nut into the interior of the branch channel 25 until the nut moves to the upper surface of the flat plate 61. The piston rod of the telescopic cylinder 34 squeezes the multi-group flat plates 61 to turn over through the nut, so that the nut moves into the guiding cylinder 35 and moves along the inner wall of the guiding cylinder 35 into the workpiece hole position, and the nut is hot-melt installed inside the hole position under the heating action of the piston rod of the telescopic cylinder 34; Finally, during the reset process of the moving plate 41, the moving plate 41 drives the positioning rod 46 to move through the positioning groove 45. The positioning rod 46 moves along the inclined bottom surface of the moving groove 54 with the help of the ball 53, so that the disc 47 disengages from the placement groove 52 and the top of the positioning rod 46 gradually moves upward relatively until the positioning rod 46 moves to the initial position for implanting the next nut.
