[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. Injection molding machines are divided into vertical, horizontal, and all-electric types. Injection molding machines heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity;

[0003] Injection molding machines can process plastics quickly and are very popular in the plastics field and are widely used. After the plastic parts are formed, the injection molding machine often uses a robot to take the material. The existing robot can replace manual material taking and can flexibly take the material according to the production situation to avoid burns to the staff during the material taking process.

[0004] However, the movements of existing manipulators in all directions are mostly controlled by cylinders, which is not convenient for conveying over long routes. At the same time, the directions of the existing manipulator claws are mostly fixed, which has low adaptability.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A new mechanical picker for an injection molding machine comprises an X-axis guide rail 1 and a Y-axis guide rail 2, wherein the top of the X-axis guide rail 1 is slidably provided with the Y-axis guide rail 2, the top of the Y-axis guide rail 2 is provided with a slide groove 3, the inner side of the slide groove 3 is slidably connected with an L-shaped seat 4, a rotating seat 5 is movably penetrated through one side of the top of the L-shaped seat 4, a first cylinder 6 is installed on the top of the rotating seat 5, one end of the output shaft of the first cylinder 6 penetrates through the rotating seat 5 and is connected with a clamp 7, a driving disk 8 is fixedly connected to the bottom end of the rotating seat 5, a first gear 81 is fixedly sleeved on the outer bottom end of the driving disk 8, a driving motor 9 is installed on the other side of the top of the L-shaped seat 4, one end of the output shaft of the driving motor 9 penetrates through the L-shaped seat 4 and is fixedly connected with a second gear 10, and the second gear 10 is meshed with the first gear 81;

[0023] The technical solution adopted above sets an X-axis guide rail 1 and a Y-axis guide rail 2 to facilitate the movement of the clamp 7 in the X-axis and Y-axis directions. The X-axis guide rail 1 is relatively long and can transport items over a longer route. The Y-axis guide rail 2 and the first cylinder 6 are used to adjust the precise position of the clamp 7 so that it can clamp the corresponding formed products. The upper and lower positions of the clamp 7 are adjusted by the extension and retraction of the first cylinder 6. The second gear 10 is driven to rotate by the driving motor 9, and then the first gear 81 and the second gear 10 are driven to rotate the rotating seat 5 to a corresponding angle, thereby driving the first cylinder 6 and the clamp 7 to adjust the horizontal angle to improve the adaptability of the clamp 7.

[0024] A sliding hole 31 penetrating the Y-axis guide rail 2 is provided at the bottom of the slide groove 3, and the bottom of the rotating seat 5 movably penetrates the sliding hole 31. A limiting ring is provided on the top fixed sleeve of the outer side of the rotating seat 5, and the limiting ring fits the top surface of the L-shaped seat 4, and the top edge of the driving disk 8 fits the bottom surface of the Y-axis guide rail 2;

[0025] In the technical solution adopted above, the setting of the sliding hole 31 is to facilitate the rotating seat 5 to pass through the Y-axis guide rail 2, so that it is not only convenient for the rotating seat 5 to follow the L-shaped seat 4 to translate along the direction of the slide groove 3, but also does not affect the rotational movement of the rotating seat 5 itself. The diameters of the limit ring and the driving disk 8 are both larger than the rotating seat 5, and the diameter of the driving disk 8 is larger than the width of the sliding hole 31, thereby achieving the effect of limiting the upper and lower positions of the rotating seat 5 so that it can only perform rotational movement.

[0026] A second cylinder 11 is installed at the top of the Y-axis guide rail 2 through a support plate 12, and one end of the output shaft of the second cylinder 11 is connected to the side of the L-shaped seat 4;

[0027] The technical solution adopted above can drive the L-shaped seat 4 to move along the Y-axis guide rail 2 through the second cylinder 11. The support plate 12 is arranged to lift the second cylinder 11 to a certain height to prevent its installation from affecting the activities of other components.

[0028] Transmission wheels 13 are rotatably installed on both sides of the top of the X-axis guide rail 1, and the two transmission wheels 13 are connected by a transmission belt 14. A guide column 15 is fixedly connected to the top of the transmission belt 14. A guide hole 16 is opened on the Y-axis guide rail 2, and the guide column 15 is slidably connected to the inner side of the guide hole 16. A servo motor 17 is installed on one side of the bottom end of the X-axis guide rail 1, and one end of the output shaft of the servo motor 17 passes through the X-axis guide rail 1 and is fixedly connected to the middle of one of the transmission wheels 13;

[0029] In the technical solution adopted above, the transmission belt 14 is operated through the transmission wheel 13, so that the guide column 15 makes corresponding circular motion along the direction of the transmission belt 14. When the guide column 15 moves, it will push the Y-axis guide rail 2 to move together, and can make the Y-axis guide rail 2 move back and forth. When the guide column 15 moves to the angle between the transmission belt 14 and the transmission wheel 13, it will be relatively displaced in the guide hole 16. This design enables the Y-axis guide rail 2 to have a longer range of motion, thereby facilitating the transportation of products over longer routes.

[0030] Two L-shaped plates 18 are symmetrically arranged at the bottom end of the Y-axis guide rail 2, and guide grooves 19 are opened on both sides of the X-axis guide rail 1. The adjacent ends of the two L-shaped plates 18 extend into the inner sides of the guide grooves 19 on both sides respectively. Balls 20 are movably installed on the ends and upper and lower surfaces of the L-shaped plates 18, and the balls 20 are rollingly connected with the inner walls of the guide grooves 19;

[0031] In the technical solution adopted above, the balls 20 at the ends of the L-shaped plates 18 on both sides abut against the inner walls of the guide grooves 19, and the balls 20 on the upper and lower surfaces of the L-shaped plates 18 abut against the upper and lower surfaces of the guide grooves 19. This arrangement enables the Y-axis guide rail 2 to move only along the direction of the X-axis guide rail 1 and not to move in other directions, thereby improving its activity stability. At the same time, the arrangement of the balls 20 can reduce friction.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
