Description

Technical Field

[0001] The utility model relates to a material taking and placing mechanism, in particular to a full-automatic injection molding material taking and placing mechanism, belonging to the technical field of injection molding production equipment. Background Technique

[0002] With the improvement of the level of production automation, the application of programmable manipulators and robots to automatically execute production tasks is also increasing. Modern injection molding machines are often equipped with manipulators, which are required to pick up the products produced by the injection molding machines and place them at predetermined positions to improve production efficiency. For special products and specific molds, the manipulators cannot achieve the required effects, so fixtures need to be used to achieve the purpose of material taking and placing.

[0003] At present, the fixtures for automatically loading, unloading and displacing materials by manipulators have unreasonable designs, complex steps and inaccurate positioning, resulting in inconsistent positions and large errors when embedding metal parts into injection molds.

[0004] It is known that the Chinese authorized invention (publication number: CN103978647B) discloses a full-automatic injection molding material taking and receiving method and a robot for implementing the method. Through structural optimization and the operation mode of sucking metal parts by negative pressure, it is fast, stable and reliable in performance. The fixture for automatically loading, unloading and displacing materials by a manipulator is provided with positioning pins on the fixture to improve the accuracy of the position where the metal parts are embedded into the injection mold;

[0005] It respectively sets a feeding part and a discharging part, and the structure is relatively complex. Moreover, the positions of the feeding part and the discharging part are fixed and cannot be adjusted according to actual use requirements, so the overall applicability is not high. Therefore, a full-automatic injection molding material taking and placing mechanism is proposed. Summary of the Utility Model

[0006] In view of this, the utility model provides a full-automatic injection molding material taking and placing mechanism to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0007] The technical solution of the embodiment of the utility model is realized as follows: a full-automatic injection molding material taking and placing mechanism includes a main body component, and the main body component includes a mounting plate, four mounting grooves, four mounting seats, a double-headed lead screw, a driving motor, a fixed pipe, a suction pipe, a suction head, a pressure ring, three pressure sensors, a spring and a limit ring;

[0008] The four mounting grooves are symmetrically formed on the upper surface of the mounting plate. The four mounting seats are symmetrically and slidably connected to the inner side walls of the four mounting grooves. Two corresponding mounting seats are symmetrically and threadedly connected to the outer side wall of the double-headed screw rod. One end of the double-headed screw rod is fixedly connected to the output shaft of the driving motor. The top end of the fixed tube is fixedly connected to the lower surface of the mounting seat. The suction pipe is slidably connected to the inner side wall of the fixed tube. The spring is sleeved on the outer side wall of the suction pipe. The suction head is mounted at the bottom end of the suction pipe. The limiting ring is fixedly connected to the outer side wall of the suction pipe. The three pressure sensors are symmetrically mounted on the upper surface of the pressure ring.

[0009] Further preferably, the pressure sensors are mounted on the lower surface of the mounting seat, and the outer side wall of the pressure ring is slidably connected to the inner side wall of the fixed tube.

[0012] Further preferably, the driving motor is mounted inside the mounting plate, and the double-headed screw rod is rotatably connected inside the mounting plate.

[0013] Further preferably, an air pipe is mounted at the top end of the suction pipe. The air pipe is communicated with the suction pipe, and the top end of the air pipe is located above the mounting seat.

[0016] Further preferably, a positioning pin is mounted on the lower surface of the mounting plate.

[0017] Due to the adoption of the above technical solutions in the embodiments of the present utility model, it has the following advantages: The present utility model adsorbs materials through the suction head. Driven by the robotic arm, the feeding of materials can be realized. By driving the motor to drive the double-headed lead screw to rotate, the distance between the corresponding two suction heads can be adjusted to be applicable to the material taking process. When taking materials, the robotic arm drives the mounting plate to move downward, so that the bottom end of the suction head contacts the product. After the suction head contacts the product, the straw is pushed by the force, and the suction head adsorbs the product. Driven by the robotic arm, the suction head takes out the product from the mold. Compared with the prior art, the present utility model simplifies the structure and improves the applicability by setting the adjustment mechanism, so that the suction head can meet the two processes of feeding and material taking. Moreover, a pressure sensor is set, which can ensure the close contact between the suction head and the product, improve the adsorption effect on the product, avoid the situation of dropping when taking out the product, and at the same time avoid the product being crushed.

Detailed implementation manners

[0026] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0027] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0028] As Figures 1-5 shown, an embodiment of the present invention provides a fully automatic injection molding picking and placing mechanism, including a main body assembly 101. The main body assembly 101 includes a mounting plate 11, four mounting grooves 12, four mounting seats 13, a double-headed lead screw 14, a drive motor 15, a fixed tube 16, a suction pipe 18, a suction head 19, a pressure ring 20, three pressure sensors 21, a spring 22, and a limit ring 23;

[0029] The four mounting grooves 12 are symmetrically formed on the upper surface of the mounting plate 11. The four mounting seats 13 are symmetrically and slidably connected to the inner side walls of the four mounting grooves 12. The two corresponding mounting seats 13 are symmetrically and threadedly connected to the outer side wall of the double-headed lead screw 14. One end of the double-headed lead screw 14 is fixedly connected to the output shaft of the drive motor 15. The top end of the fixed tube 16 is fixedly connected to the lower surface of the mounting seat 13. The suction pipe 18 is slidably connected to the inner side wall of the fixed tube 16. The spring 22 is sleeved on the outer side wall of the suction pipe 18. The suction head 19 is installed at the bottom end of the suction pipe 18. The limit ring 23 is fixedly connected to the outer side wall of the suction pipe 18. The three pressure sensors 21 are symmetrically installed on the upper surface of the pressure ring 20.

[0030] In one embodiment, the pressure sensor 21 is installed on the lower surface of the mounting seat 13. The outer side wall of the pressure ring 20 is slidably connected to the inner side wall of the fixed tube 16. The limit ring 23 is slidably connected to the inner side wall of the fixed tube 16. The pressure sensor 21 is located inside the fixed tube 16. The top end of the spring 22 abuts against the pressure ring 20, and the bottom end of the spring 22 abuts against the limit ring 23;

[0031] When picking up materials, the robotic arm 31 drives the mounting plate 11 to move downward, the mounting plate 11 drives the suction head 19 to move downward, so that the bottom end of the suction head 19 contacts the product. After the suction head 19 contacts the product, the force pushes the suction pipe 18. The suction pipe 18 squeezes the spring 22 through the limiting ring 23, and the spring 22 pushes the pressure ring 20 upward. The pressure ring 20 pushes the pressure sensor 21. Thus, the pressure received by the product can be detected through the pressure sensor 21. When the pressure reaches the rated value, the suction head 19 adsorbs the product. Driven by the robotic arm 31, the suction head 19 takes out the product from the mold. By setting the pressure sensor 21, it can ensure that the suction head 19 is in close contact with the product, improve the adsorption effect on the product, avoid the situation of dropping when taking out the product, and at the same time avoid damaging the product.

[0032] In one embodiment, the driving motor 15 is installed inside the mounting plate 11, and the double-headed lead screw 14 is rotatably connected inside the mounting plate 11. The driving motor 15 drives the double-headed lead screw 14 to rotate, and the double-headed lead screw 14 drives the mounting seat 13 through the thread, so that the two corresponding suction heads 19 can move away from each other, thereby realizing the adjustment of the position of the suction head 19 and being applicable to different usage requirements.

[0033] In one embodiment, an air pipe 17 is installed at the top end of the suction pipe 18. The air pipe 17 is communicated with the suction pipe 18. The top end of the air pipe 17 is located above the mounting seat 13, and the air pipe 17 is communicated with an external vacuum pump, so that the suction pipe 18 can adsorb the product.

[0034] In one embodiment, a driving assembly 301 is installed on one side of the mounting plate 11. The driving assembly 301 includes a robotic arm 31, a connecting seat 32 and a mounting hole 33;

[0035] The connecting seat 32 is fixedly connected to one side of the mounting plate 11, the mounting hole 33 is opened on the upper surface of the connecting seat 32, and the robotic arm 31 is connected to the mounting plate 11 through the connecting seat 32. By setting the connecting seat 32 and the mounting hole 33, it is convenient to install and connect the robotic arm 31 and the mounting plate 11.

[0036] In one embodiment, a positioning pin 24 is installed on the lower surface of the mounting plate 11, and the positioning pin 24 can play a role in positioning and guiding.

[0037] When the present utility model is working: when discharging materials, the robotic arm 31 drives the mounting plate 11 to move, the suction head 19 adsorbs the materials, then the robotic arm 31 drives the mounting plate 11 to move above the mold, and the robotic arm 31 drives the materials to move downward, so that the materials can be put into the mold, and at this time, injection molding work can be carried out;

[0038] The driving motor 15 drives the double-headed lead screw 14 to rotate. The double-headed lead screw 14 drives the mounting seat 13 through the thread, enabling the two corresponding suction heads 19 to move away from each other, thereby realizing the adjustment of the position of the suction heads 19 to be applicable to the material taking process.

[0039] During material taking, the robotic arm 31 drives the mounting plate 11 to move downward, making the bottom end of the suction head 19 contact the product. After the suction head 19 contacts the product, it forces the straw 18. The straw 18 squeezes the spring 22 through the limiting ring 23, and the spring 22 pushes the pressure ring 20 upward. The pressure ring 20 pushes the pressure sensor 21. Thus, the pressure received by the product can be detected through the pressure sensor 21. When the pressure reaches the rated value, the suction head 19 adsorbs the product, and under the drive of the robotic arm 31, the suction head 19 takes out the product from the mold.

[0040] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
