Description

Technical Field

[0001] The present application relates to the technical field of hot melt machines, and specifically discloses a nut hot melt machine. Background Art

[0002] There are several ways to embed copper nuts into plastic parts, such as mold forming pre-embedding, hot pressing, ultrasonic pressing, cold pressing, etc. Among them, hot melt embedding is the most common and most common embedding method. The hot melt embedding process of the nut is to heat the copper nut to a certain temperature to soften the plastic, and then press it into the plastic part. This method produces less internal stress, and the torsion and tension effect of the nut is also very good.

[0003] However, in the existing nut hot-melt embedding process, nut implantation is usually carried out manually or during the plastic part injection molding process. Manual nut implantation requires workers to use a soldering iron to heat the nut and melt the nut into the plastic part. Due to high-temperature operation, there is a phenomenon of harm to the workers. At the same time, the operation efficiency is low and the welding quality is uneven. Although the welding quality is good during the implantation process of plastic parts, the structure of the plastic mold is complicated, the mold volume becomes larger, and the difficulty of subsequent demolding is increased. Therefore, in view of this, the inventor provides a nut hot-melt machine to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problems of high labor intensity and uneven welding quality in the traditional nut hot-melt embedding process.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a nut hot melt machine, comprising:

[0006] A chassis, wherein a loading station and a hot-melt station are arranged in the chassis, and a loading platform is slidably connected between the loading station and the hot-melt station;

[0007] A moving mechanism drives the stage to slide back and forth;

[0008] A vibrating feeding tray is arranged outside the chassis and connected with a feeding trough;

[0009] The gripping mechanism includes an electric gripper that can grip the nuts in the feeding trough to the loading station and a driving assembly that drives the electric gripper to move;

[0010] The hot melt mechanism includes a vertical driving member located directly above the hot melt station, a pressure plate driven by the vertical driving member, a hot melt plate arranged below the pressure plate, and a plurality of hot melt heads buried in the hot melt plate. A reset member for driving the hot melt plate to reset is arranged in the chassis.

[0011] The principles and effects of this basic solution are:

[0012] Compared with the prior art, the utility model feeds nuts through a vibrating feed plate, and at the same time places plastic parts that need to be implanted with nuts through a loading platform, and then uses a grabbing mechanism to grab the nuts in the feeding trough to the corresponding implantation positions of the plastic parts on the loading platform in turn, and uses a moving mechanism to move the loading platform and the plastic parts and nuts on the loading platform to the hot melt station, and the vertical driving member presses the pressing plate downward so that the hot melt head on the hot melt plate contacts the nut, thereby heating the nut. After heating for a period of time, the vertical driving member drives the pressing plate to further press the hot melt plate downward, so that the nut is completely pressed into the plastic part, thereby completing the hot melt implantation process of the nut to the plastic part. The utility model can quickly and conveniently perform hot melt implantation of nuts on plastic parts after the plastic parts are formed, and the molding quality is easy to control. While not increasing the difficulty of plastic part molding, it also solves the problems of high manual labor intensity and uneven welding quality in the traditional nut hot melt implantation process.

[0013] Further, the moving mechanism comprises:

[0014] The stage driving cylinder is arranged in the chassis;

[0015] Slide rail, located between the loading station and the hot-melt station;

[0016] The slide table is driven by the loading platform driving cylinder and is slidably connected with the slide rail.

[0017] The slide rail is used for limiting and guiding, and the stage driving cylinder is used for driving, so as to conveniently drive the slide and the stage to move back and forth between the loading station and the hot melting station.

[0018] Furthermore, the loading platform is arranged on the slide and a heat insulation board is arranged between the slide, and the heat insulation board can protect the slide and the loading platform driving cylinder.

[0019] Further, the driving assembly comprises:

[0020] An X-axis ball nut screw pair, wherein the sliding direction of the nut seat in the X-axis ball nut screw pair is parallel to the direction of the slide rail;

[0021] A Y-axis ball nut screw pair is arranged on a nut seat in the X-axis ball nut screw pair, and a sliding direction of the nut seat in the Y-axis ball nut screw pair is perpendicular to the slide rail;

[0022] The Z-axis cylinder is arranged on the nut seat in the Y-axis ball nut screw pair, and the piston rod of the Z-axis cylinder is vertically connected downward to a mounting plate for mounting the electric clamp.

[0023] By setting the X-axis ball nut screw pair, the Y-axis ball nut screw pair and the Z-axis cylinder, the electric clamp can be adjusted in multiple directions to facilitate clamping the nut to the corresponding implantation position of the plastic part.

[0024] Furthermore, the electric clamps are multiple and detachably connected to the mounting plate, so that multiple nuts can be grasped at the same time.

[0025] Furthermore, a plurality of vertical guide rods are arranged around the hot melt station, and the pressing plate and the hot melt plate are both slidably connected to the guide rods, which play the role of limiting and guiding the pressing plate and the hot melt plate.

[0026] Further, the reset member is a reset spring sleeved on the outer wall of each guide rod and in contact with the hot melt plate. The reset spring facilitates the hot melt plate to be reset. BRIEF DESCRIPTION OF THE DRAWINGS
