After the substrate 3, the suction cup 4 and the workpiece are moved to the side of the static mold 1 and the dynamic mold 2, the substrate 3, the suction cup 4 and the workpiece are rotated to lower the height of the workpiece, and then the suction cup 4 is operated to release the work.
[0018] Furthermore, if Figure 2 and Figure 6 As shown, the driving mechanism includes a rotating plate 5, on which a driving rod 1 7 is rotatably mounted via a rotating shaft 1 6, on which a driving rod 2 9 is rotatably mounted via a rotating shaft 2 8, on which an end of the driving rod 1 7 away from the rotating plate 5 is rotatably mounted a driving rod 3 11 via a rotating shaft 3 10, a middle portion of the driving rod 3 11 is rotatably connected to a middle portion of the driving rod 2 9 via a rotating shaft 4 12, an end of the driving rod 3 11 away from the driving rod 1 7 is rotatably mounted a driving rod 4 14 via a rotating shaft 5 13, an end of the driving rod 4 14 away from the driving rod 3 11 is rotatably mounted a connecting plate 16 via a rotating shaft 6 15, an end of the connecting plate 16 away from the driving rod 4 14 is rotatably connected to an end of the driving rod 29 away from the rotating plate 5 via a rotating shaft 6 15, and the connecting plate 16 is fixed on the base plate 3; The driving rod three 11 is in a horizontal state, the driving rod one 7, the driving rod two 9 and the driving rod four 14 are parallel to each other, the driving rod three 11 and the connecting plate 16 are parallel to each other, the axis connecting line of the rotating shaft one 6 and the rotating shaft two 8, the axis connecting line of the rotating shaft three 10, the rotating shaft four 12 and the rotating shaft five 13, and the axis connecting line of the rotating shaft six 15 and the rotating shaft seven are parallel to each other, through the above arrangement, the rotating plate 5, the driving rod one 7, the driving rod two 9 and the driving rod three 11 form a parallelogram linkage mechanism, the driving rod three 11, the connecting plate 16, the driving rod two 9 and the driving rod four 14 form a parallelogram linkage mechanism, and in order to increase the stroke, when the suction cup 4 does not enter between the static mold 1 and the movable mold 2, the driving rod two 9 gradually moves away from the static mold 1 and the movable mold 2 from bottom to top; In this embodiment, if Figure 1-2 and Figure 6As shown in, when the substrate 3 and the suction cup 4 need to be moved, the driving rod 1 7 or the driving rod 2 9 is rotated counterclockwise, and the driving rod 3 11 will be lifted while approaching the static mold 1 and the dynamic mold 2, and the connecting plate 16, the suction cup 4 and the substrate 3 will be lifted while approaching the static mold 1 and the dynamic mold 2, and the angles of the substrate 3 and the suction cup 4 will not change, and the driving rod 1 7, the driving rod 2 9, the driving rod 3 11, the driving rod 4 14 and the driving rod 5 will all undergo adaptive changes. When the suction cup 4 moves to the workpiece, the driving rod 1 7 or the driving rod 2 9 is stopped from rotating to stop the suction cup 4; After the suction cup 4 sucks the workpiece, the driving rod 1 7 or the driving rod 2 9 is rotated in the reverse direction, and the suction cup 4, the connecting plate 16 and the workpiece gradually return to their initial positions.
[0019] Furthermore, if Figure 1 , Figure 2 and Figure 6 As shown, the rotating mechanism includes a fixed support plate 18, on which a support shaft 19 is rotatably mounted, the support shaft 19 is fixedly connected to the rotating plate 5, and a power assembly 20 is arranged at the end of the support shaft 19; The support plate 18 needs to be fixed from the outside; In this embodiment, the power component 20 uses a servo motor. When the suction cup 4 and the like need to be rotated, the servo motor is operated to drive the support shaft 19 to rotate, thereby driving the rotating plate 5 and the components thereon to rotate around the support shaft 19.
[0020] Furthermore, if Figure 3 , Figure 5 and Figure 7 As shown, a slider 1 21 slides on the substrate 3, a slider 2 22 slides on the slider 1 21, a mounting plate 23 is fixed on the slider 2 22, and the suction cup 4 is fixed on the mounting plate 23; The slider 1 21 slides on the track 1 24 fixedly connected to the base plate 3, and the slider 2 22 slides on the track 2 25 fixedly connected to the slider 1 21. The track 1 24 is perpendicular to the track 2 25, so that the suction cup 4 can move in the horizontal direction and the vertical direction; In this embodiment, when the position of the suction cup 4 needs to be adjusted according to the workpiece, the slider 1 21 is made to slide on the track 1 24, the slider 2 22 is made to slide on the track 2 25, and then the slider 1 21 and the slider 2 22 are fixed, so that the position of the suction cup 4 can be adjusted within a certain range.
[0021] Furthermore, if Figure 3 , Figure 5 and Figure 7As shown, it also includes an adjustment mechanism disposed on the base plate 3 for adjusting the position of the suction cup 4, the adjustment mechanism includes a main shaft 26 rotatably connected to the base plate 3, a driving arm 27 is fixed to one end of the main shaft 26, the other ends of the two driving arms 27 are slidably matched with the mounting plate 23, and a swing arm 28 is fixed to the other end of the main shaft 26; The adjustment mechanism also includes two screw rods 29 rotatably mounted on the base plate 3, the screw rods 29 are threadedly connected with a driving block 30, the driving block 30 is fixed with a driving shaft 31, and the driving shaft 31 is slidably matched with the swing arm 28; Two adjacent side walls of the mounting plate 23 are provided with a long hole 32, and a power shaft 33 is fixed to the other end of the driving arm 27, and the two power shafts 33 are respectively inserted into the two long holes 32; The screw rod 29 is rotatably mounted on a bearing seat fixed to the mounting plate 23. A guide rod passing through the driving block 30 is also fixed on the bearing seat. A second long hole is provided on the swing arm 28. The driving shaft 31 passes through the second long hole. In order to reduce the wear of the driving shaft 31 and the power shaft 33, bearings are installed at the ends of the driving shaft 31 and the power shaft 33, respectively contacting the inner walls of the first long hole 32 and the second long hole. In this embodiment, when it is necessary to adjust the position of the suction cup 4, one of the screw rods 29 is rotated, and the driving block 30 and the driving shaft 31 are moved under the action of the guide rod. Since the driving shaft 31 passes through the long hole 2 on the swing arm 28, the main shaft 26, the driving arm 27 and the power shaft 33 at the corresponding position are pushed to rotate around the axis of the main shaft 26, so that the slider 1 21 or the slider 2 22 slides, and when one of the main shafts 26 rotates, the power shaft 33 on the other driving arm 27 slides relative to the long hole 1 32, which will not affect the movement of the mounting plate 23, thereby adjusting the position of the suction cup 4.
[0022] Furthermore, if Figure 2 As shown, the driving mechanism also includes a cylinder 34 fixed on the rotating plate 5, a driving shaft 35 is fixed to the output end of the cylinder 34, an extension rod 36 is fixed to one end of the rotating shaft 6, and the driving shaft 35 and the extension rod 36 are slidably matched; The extension rod 36 is provided with a third long hole, and the driving shaft 35 passes through the third long hole; In this embodiment, when the suction cup 4 needs to be moved, the operating cylinder 34 moves the driving shaft 35. Since the driving shaft 35 passes through the long hole three on the extension rod 36 and the driving shaft 35 is fixedly connected to the rotating shaft 6, the rotating shaft 6 and the driving rod 7 are driven to rotate, thereby causing the suction cup 4 to perform corresponding actions.
[0023] Furthermore, two nuts 37 are threadedly connected to the screw rod 29, and the two nuts 37 are distributed on both sides of the driving block 30; In this embodiment, after the position of the suction cup 4 is adjusted, the nut 37 is tightened to fix the position of the suction cup 4 .
[0024] Furthermore, it also includes a conveyor belt 38, which is located on one side of the rotating plate 5; In this embodiment, the workpiece is placed on the conveyor belt 38, and the conveyor belt 38 conveys the workpiece to another location.
[0025] When in use, the position of the suction cup 4 on the base plate 3 is adjusted by rotating the screw rod 29 according to the position of the workpiece. After the static mold 1 and the movable mold 2 are separated, the servo motor is operated to rotate the base plate 3 and the suction cup 4 to a vertical state to prevent damage to other components during the movement between the static mold 1 and the movable mold 2. Then, the cylinder 34 is operated to move the driving shaft 35 to the left to move the base plate 3 and the suction cup 4 between the static mold 1 and the movable mold 2. When the suction cup 4 is just facing the molded workpiece, the cylinder 34 is stopped. Then, the ejector pin (not shown) on the movable mold 2 is operated to move the molded workpiece to separate the molded workpiece from the movable mold 2. Then, the servo motor is operated to rotate the base plate 3 and the suction cup 4 to a vertical state to prevent damage to other components during the movement between the static mold 1 and the movable mold 2. The suction cup 4 sucks the workpiece, and then the cylinder 34 is operated to move the driving shaft 35 to the right, so that the substrate 3, the suction cup 4 and the workpiece are moved to the side of the static mold 1 and the dynamic mold 2, and then the cylinder 34 is stopped, and the static mold 1 and the dynamic mold 2 are restarted for the next injection molding. After the substrate 3, the suction cup 4 and the workpiece are moved to the side of the static mold 1 and the dynamic mold 2, the servo motor is operated to rotate the substrate 3, the suction cup 4 and the workpiece to lower the height of the workpiece. When the workpiece is directly above the conveyor belt, the servo motor is stopped, and then the suction cup 4 is operated to release the work, and the workpiece falls onto the conveyor belt and is transported to other positions by the conveyor belt.
[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
