Abstract
Description
Technical Field
[0001] This utility model belongs to the field of injection molding processing technology, specifically relating to an automatic pin embedding fixture. Background Technology
[0002] When injection molded parts are joined, snap-fit components are used. Some parts also include screws and nuts to improve the connection. The screws need to be fixed to the injection molded parts first, and then the injection molding process is carried out. After cooling and molding, the screws are fixed in the injection molded parts. The screw embedding work needs to be done manually during the manufacturing process. Manual work is inefficient and it is difficult to ensure consistency and precision. This can lead to pressure film phenomenon during injection molding and may also result in loose connections during assembly.
[0003] To address the aforementioned problems, this application proposes an automatic nail-embedding fixture. Utility Model Content

[0007] As a preferred technical solution of this utility model, the gripper is provided in two parts, which are driven by a cylinder, and the inner side of the gripper is formed with an arc-shaped groove for holding the positioning screw.
[0008] As a preferred technical solution of this utility model, the mounting plate and the base plate are distributed in parallel, and there is a clearance between them through the upright plate for connecting an external air source to the air nozzle interface.
[0009] As a preferred embodiment of this utility model, one side of the mounting plate extends outward, and the extended portion is provided with several mounting holes.
[0010] As a preferred embodiment of this utility model, the positioning screw and the mold pre-embedded nail are at the same center.
[0011] Compared with the prior art, the beneficial effects of this utility model are: this utility model sets the positions of the positioning screw and the embedded nail to be concentrically distributed, and achieves precise positioning of the embedded nail position by clamping the positioning screw. Then, the screw is placed in the mold by a robotic arm, which has the advantages of high automation, high efficiency and high product consistency, while also reducing labor costs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example
[0021] Please see Figure 1-3The present invention provides the following technical solution: an automatic nail embedding fixture, including a machine base 1, an mounting plate 2 below the machine base 1, an adjustable movable seat 3 at the upper end of the mounting plate 2, a cylinder 4 fixed at the upper end of the movable seat 3, a gripper 5 fixed at the output end of the cylinder 4, a vertical plate 6 vertically fixed at the bottom of the mounting plate 2, a base plate 7 fixed at the bottom of the vertical plate 6, a suction cup 8 installed on the base plate 7, an air nozzle interface 9 provided at the upper end of the suction cup 8, and a positioning screw 13 fixed at the bottom of the machine base 1. In this embodiment, a positioning component concentric with the position of the pre-embedded nail on the mold can be installed at the bottom of the suction cup 8 or the base plate 7.
[0022] Specifically, the mounting plate 2 has a sliding groove 10 for the sliding of the movable seat 3, and the mounting plate 2 also has multiple fixing holes 11. The movable seat 3 is fixed to the mounting plate 2 by bolts passing through the fixing holes 11 and screws. In this embodiment, it is set as an adjustable structure, which can be adjusted according to the deviation of the positioning screw 13 and the pre-embedded nail position, and has higher adaptability and better practicality.
[0023] Specifically, there are two grippers 5, which are driven by cylinder 4. The inner side of the gripper 5 is formed with an arc-shaped groove for holding the positioning screw 13. In this embodiment, the gripper 5 clamps and releases the positioning screw 13 by driving the cylinder 4, which can not only ensure the accuracy of the pre-embedded screw position, but also facilitate the removal of the injection molded part.
[0024] Specifically, the mounting plate 2 and the base plate 7 are distributed in parallel, and there is a clearance between them through the upright plate 6 for the external air source to be connected to the air nozzle interface 9. In this embodiment, sufficient installation space is provided for the suction cup 8 to connect to the external air source.
[0025] Specifically, one side of the mounting plate 2 extends outward, and the extended portion has several mounting holes 12. In this embodiment, the automatic nail-embedding fixture is connected to an external robotic arm or handling unit through the mounting holes 12 on the mounting plate 2, facilitating the removal of the injection molded parts.
[0026] Specifically, the positioning screw 13 and the mold pre-embedded nail are at the same center. In this embodiment, the robot arm that picks up the pre-embedded screw performs the pre-embedded nail work with the center of the positioning screw 13 facing the mold. The robot arm operation has the advantages of high efficiency and consistency. Positioning by the positioning screw 13 can effectively ensure the accuracy of the nail embedding.
[0027] The working principle and usage process of this utility model are as follows: The position of the movable seat 3 on the mounting plate 2 is adjusted by the slide groove 10 to ensure that the positioning screw 13 is concentric with the position of the embedded screw on the mold. Then, the movable seat 3 is locked by the bolt through the fixing hole 11. The mounting plate 2 is installed on the robotic arm or a transportable unit through the mounting hole 12. The robotic arm that clamps and delivers the screw is adjusted to a position concentric with the positioning screw 13.
[0028] During operation: The transport unit moves the gripper 5 to the bottom of the machine base 1. The cylinder 4 drives the gripper 5 to clamp the positioning screw 13. At this time, the screw hole on the mold is concentric with the pre-embedded position. The robot arm picks up the screw and puts it into the pre-embedded hole. The mold performs injection molding. After injection molding is completed, the pre-embedded screw is fixed on the injection molded part. The suction cup 8 adsorbs the injection molded part. The gripper 5 releases its grip on the positioning screw 13. The transport unit takes the molded part out of the mold.
[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
