Abstract
The invention discloses a method for solving the problem of instability of an intramode implanted copper nut, which comprises the following steps: (1) during the preparation stage, fixing the sleeve assembly at the corresponding position of the jig plate, and fixing the copper nut base with the corresponding specification at the corresponding position of the base plate; (2) during operation, a copper nut with a corresponding specification is sleeved on a copper nut base by using special equipment, and the copper nut sleeved on the copper nut base is transferred into a copper nut sleeve by a manipulator; (3) the manipulator sends the jig plate which has grabbed the copper nut into the die, the copper nut sleeve is sent to the surface of the die by the aid of a corresponding guide mechanism and then stopped, and the pressing plate is pushed by the cylinder to enable the ejector pin to move forwards so as to push the copper nail into the die; (4) the robot is slowly withdrawn from the mold surface. Compared with the traditional negative pressure adsorption mode, the method can save the molding period by about 3 seconds, and the yield is improved to more than 99% from 90%.
Description
Technical Field
The invention belongs to the field of electronic products, and particularly relates to a method for solving the problem of instability of an intramode implanted copper nut.
Background
The conventional method for embedding the copper nut into the plastic part is to firstly inject and mold the plastic product and then embed the copper nut into the plastic product by hot melting or ultrasonic wave. In recent years, with the increase of manpower cost, notebook computers, mobile phones, routers and the like are developed in the direction of lightness and thinness, so that higher requirements are placed on the drawing force and the torsion of copper nuts embedded in plastic parts.
Because the copper nut that uses in the 3C trade is less (generally between M1.6-M3) the terminal surface can supply absorptive area littleer, and the mould surface structure who is buried is complicated, can produce the turbulent phenomenon of air at the copper nut by inhaling the in-process that changes to blow, leads to the unable accurate stop of copper nut at silk section of thick bamboo inner needle step department on the mould to lead to the shaping back, the degree of depth that the copper nut buried differs, influences the yield.
Disclosure of Invention
The invention provides a method for solving the instability of implanting a copper nut in a mould aiming at the problems in the background technology, and the method solves the instability of implanting the copper nut in the mould in a flexible mode.
The technical scheme of the invention is as follows: a method for solving instability of an in-mold implanted copper nut comprises the following steps:
1. during the preparation stage, fixing the sleeve assembly at the corresponding position of the jig plate, and fixing the copper nut base with the corresponding specification at the corresponding position of the base plate;
2. during operation, a copper nut with a corresponding specification is sleeved on a copper nut base by using special equipment, a manipulator grabs a jig plate, the position is adjusted, and the copper nut sleeved on the copper nut base is transferred into a copper nut sleeve;
3. the manipulator sends the jig plate which has grabbed the copper nut into the die, the copper nut sleeve is sent to the surface of the die by the aid of a corresponding guide mechanism and then stopped, and the pressing plate is pushed by the cylinder to enable the ejector pin to move forwards so as to push the copper nail into the die;
4. the manipulator is slowly withdrawn from the surface of the mould, and at the moment, the end part of the thimble still stays on the surface of the mould due to the action of the spring; and after the manipulator is completely withdrawn, the ejector pin is separated from the surface of the copper nail, and the mold continues to perform injection molding operation.
The invention has the beneficial effects that:
1. the mode of mechanical clamping is adopted to replace the mode of negative pressure adsorption. The copper nut structure of implanting in the mould is "worker" style of calligraphy, and the recess in the middle of this scheme utilization "worker" word uses 2 steel balls to add the elastic material of steel ball outside to carry out the centre gripping to the copper nut, ensures the centre gripping of tool (copper nut sleeve) to the copper nut.
2. The semi-flexible mechanism realized by the spring gives a certain force to the copper nut after the copper nut is sent into the die, and the force of the spring continuously acts on the copper nut in the process of retreating the copper nut sleeve, so that the separation of the copper nut and the boss of the inner needle of the ejector sleeve can not be caused by the separation of the copper nut sleeve.
3. Compared with the traditional negative pressure adsorption mode, the method can save the molding period by about 3 seconds, and the yield is improved to more than 99% from 90%.
Drawings
The invention is further described with reference to the following figures and examples:
FIG. 1 is a schematic structural view of the mechanism;
FIG. 2 is a schematic structural view of the copper nut base;
wherein: 1. fixed marble, 2, copper nut sleeve, 3, thimble, 4, spring, 5, clamp plate fixing base, 6, copper nut base.
Detailed Description
Example (b): referring to fig. 1-2, the method for solving the instability of the copper nut implanted in the mold provided by the invention comprises the following steps:
1. during the preparation stage, the sleeve assembly is fixed at the corresponding position of the jig plate, and the copper nut base with the corresponding specification is fixed at the corresponding position of the base plate.
2. During operation, the copper nut of corresponding specification is sleeved on the copper nut base by using special equipment, the manipulator grabs the jig plate, the position is adjusted, and the copper nut sleeved on the copper nut base is transferred into the copper nut sleeve.
3. The manipulator sends the jig plate which has grabbed the copper nut into the die, the corresponding guide mechanism is used for assisting, the copper nut sleeve is sent into the surface of the die and then stops, the air cylinder is used for pushing the pressing plate, the ejector pin moves forwards, and the copper nail is pushed into the die.
4. The manipulator is slowly withdrawn from the surface of the mould, at which time the end of the thimble remains on the surface of the mould due to the action of the spring. And after the manipulator is completely withdrawn, the ejector pin is separated from the surface of the copper nail, and the mold continues to perform injection molding operation.
It should be understood that the above-mentioned embodiments are only illustrative of the technical concepts and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All modifications made according to the spirit of the main technical scheme of the invention are covered in the protection scope of the invention.
