Description

Technical Field

[0001] The invention relates to the field of headphone socket production automation, and in particular to a quick-plug terminal device for headphone socket assembly equipment. Background Art

[0002] As the popularity of mobile phones increases, the quantity and quality requirements for mobile phone components are getting higher and higher. As one of the mobile phone components, the existing fully manual assembly and inspection methods or semi-automatic assembly and inspection methods have low production efficiency and low product qualification rate, resulting in high product costs and low competitiveness, which can no longer meet market demand.

[0003] In view of this situation, it is necessary to provide an automatic assembly device that can automatically, quickly and accurately plug the earphone socket into the terminal, thereby improving efficiency and reducing the occurrence of safety accidents. Summary of the invention

[0004] In order to solve the existing technical problems, the present invention provides a quick-plug terminal device for earphone socket assembly equipment.

[0005] The specific contents of the present invention are as follows: A quick-plug terminal device for an earphone socket assembly device comprises a feed assembly, a raw material cutting assembly, a plug-in terminal assembly and a base, wherein the raw material cutting assembly and the plug-in terminal assembly are arranged on the base, and the feed assembly is arranged above the raw material cutting assembly, and the plug-in terminal assembly and the raw material cutting assembly are connected; the terminals packaged in tape pass through the feed assembly, the raw material cutting assembly and the plug-in terminal assembly in sequence, and the plug-in terminal assembly is connected to the earphone socket to be plugged in.

[0006] Furthermore, the feed assembly includes a feed cylinder, a first push rod, a sliding support, a vertical linear guide, a front pawl and a rear pawl; the feed cylinder is connected to the sliding support through the first push rod, the sliding support moves on the vertical linear guide, the front pawl and the sliding support are fixedly connected by a first pin, and a first spring is provided between the front pawl and the sliding support; the rear pawl is connected to the base, and a second spring is provided between the rear pawl and the base; the sliding support moves downward, and the positioning hole on the terminal tape fits with the front pawl, and the sliding cylinder moves upward, and the positioning hole on the terminal tape fits with the rear pawl.

[0007] The sliding support is fixedly connected to the first push rod, and the front pawl and the sliding support are fixedly connected by the first pin. When the terminal braid is fed, the feeding cylinder drives the sliding support to move in the feeding direction (from top to bottom) along the vertical linear guide rail, compresses the first spring between the sliding support and the front pawl, and makes the front pawl fit with the positioning hole on the braid. The front pawl can drive the braid to move downward for a certain distance, and the rear pawl overcomes the action of the second spring under the action of the braid movement and is in a loose state; then the feeding cylinder drives the slider support to move in the opposite direction (from bottom to top). At this time, the rear pawl clamps the braid under the action of the second spring to prevent it from moving, and the front pawl overcomes the action of the first spring and loosens. When the sliding support returns to the initial position, a feeding process is completed.

[0008] Furthermore, the raw material cutting assembly includes a first cylinder, a cylinder rod, a rocker arm, a transfer block, a pressure plate, a second cylinder, a second push rod, a connecting block, a cam rod, a cutting push rod, a clamping block and a roller. The first cylinder is connected to the transfer block through the cylinder rod, the transfer block swings around the second pin, the second pin is fixed on the rocker arm, the rocker arm is provided with a pressure plate, the pressure plate is provided with a fourth pin, the cutting push rod is connected to the clamping block, the cutting push rod is provided with a cutting groove, the second cylinder is connected to the second push rod, the cam rod is connected to the second push rod through the connecting block, and the roller rolls in the cam track in the cam rod to drive the cutting push rod to move.

[0009] The terminal braid passes through the feeding assembly and reaches the raw material cutting assembly. When the terminal packaged with the braid moves downward through the cutting groove of the cutting push rod and reaches the clamping block, the first cylinder drives the push rod to extend, causing the adapter block to swing around the second pin. Since the second pin is fixedly connected to the third push rod, and the third cylinder does not move at this time, the swing rod swings until the swing rod is attached to the clamping block. The pressure plate fixed on the swing rod is equipped with the fourth pin. With the clamping action of the swing rod, the terminal braid is fixedly clamped between the swing rod and the clamping block. Then the second pin drives the second push rod to extend, and the cam rod is fixedly connected to the second push rod through the connecting block, so that the cam rod moves to the right, and the roller rolls in the cam track in the cam rod, driving the cutting push rod to retract. The braid is subjected to the shear force of the cutting groove plane and the upper plane of the clamping block, and a terminal workpiece is cut off from the braid.

[0010] Furthermore, the second cylinder controls the cutting push rod to cut the terminal braid through the planar cam mechanism, thereby improving the efficiency and accuracy of cutting and improving work efficiency.

[0011] Furthermore, two fourth pins are provided, and the pressing block has a step structure. The fourth pin is arranged vertically, and the two vertically arranged fourth pins and the step of the pressing block can accurately position the terminal braid to ensure the accuracy of cutting.

[0012] Furthermore, the plug-in terminal assembly includes a third cylinder, a third push rod and a horizontal linear guide rail; the third cylinder is connected to the third push rod, and the third cylinder pushes the third push rod to move horizontally along the horizontal linear guide rail, and the swing rod is arranged on the third push rod. After the terminal is cut from the raw material cutting assembly, the third cylinder drives the third push rod to move forward along the horizontal linear guide rail. Since the swing rod is fixed on the third push rod, the third push rod pushes the swing rod, the clamping block and the terminal workpiece clamped therein to move forward together, and the terminal is inserted into the earphone socket to be connected later.

[0013] Furthermore, the swing rod is arranged on the third push rod through the third pin, one end of the swing rod is connected to the pressing block, and the other end is arranged between the first cylinder and the third push rod. In this way, the swing rod can move on the horizontal linear guide rail through the push of the third push rod, and the adapter block swings around the second pin, and the second pin is fixed on the swing rod. Therefore, by using the principle of leverage, the swing rod can swing around the third pin and swing to the pressing block when the raw material is cut to press and fix the terminal.

[0014] The beneficial effects of the present invention are as follows: after adopting such a structure, the earphone socket can be automatically, quickly and accurately plugged into the terminal, thereby improving efficiency, reducing the occurrence of safety accidents, freeing operators from dangerous, monotonous and heavy physical labor, effectively reducing labor costs, and improving production efficiency.
