Nut implantation machine and implantation method thereof

Abstract

The invention discloses a nut implanting machine, which comprises: an implanting machine cabinet body and a machine head, the cabinet body is provided with a three-axis coordinate manipulator, and the machine head is arranged on its Z axis, wherein: the machine head is provided with an implanting device , the feeding device and the feeding tube that can withstand high temperature. The feeding tube is passed through the implanting device, and the nut to be used is installed in the feeding tube. The feeding device can push the nut into the implanting device; the feeding and implanting slide There are guide rails on both sides of the rail plate, and the nuts pass through the guide rails to connect them to the Z-axis; the invention can be used immediately, without preheating time, and can increase production capacity; it can obtain accurate process parameters without the need for manual nut placement. High pulling torque, convenient production and machine adjustment, convenient production change and high efficiency; in addition, it can solve the change of the thermal expansion coefficient of the metal material of the integrated machine head at a high temperature of 250°C-350°C to the width of the machine head.

Description

technical field [0001] The invention relates to the technical field of hot-melt implantation of plastic parts into metal parts, in particular to a nut implantation machine and an implantation method thereof. Background technique [0002] The current nut implantation machines are mainly divided into three categories: 1. In-mold injection molding: first put the required number of nuts on the rear mold of the injection molding machine mold, and wrap the nuts in the plastic by mold closing injection molding; but there are the following problems: [0003] 1. When the mold is closed and injected, the movement of the rear mold will easily cause the nut to fall off and crush the mold; [0004] 2. The movement of the nut when injecting glue makes the product column position glued; [0005] 3. The efficiency is low about 200 pieces / hour. [0006] Few manufacturers adopt this method now. [0007] 2. Hot-melt method: manually put the nut on the plastic shell, put it into the mold of ...

AI Technical Summary

Problems solved by technology

[0005] 3. Low efficiency about 200 pieces / hour

[0008] 1. Low labor efficiency: Nut preheating takes 3-6 seconds. Taking a single material to press 4 nuts as an example, 3 people are required to put the nuts and 1 person to operate, pressing 1400-1800 nuts per hour, that is, the output is 350- 450 pieces / hour

[0009] 2. Change production and adjust machine: mechanically adjust the position of the hot melt head, change production for 2-4 hours, and a large number of defective products will be produced when adjusting the machine

[0010] 3. The process parameters are unstable: the set temperature of the hot melt machine is very different from the actual temperature obtained by the nut, and it is related to factors such as the ambient temperature and wind in the workshop

[0013] 1. Nuts need to be placed manually, the same as the hot melt method

[0014] 2. The high temperature generated by the plastic and the nut cannot be measured during ultrasonication, and it is entirely dependent on experience adjustment

[0015] 3. The noise generated during ultrasound is harmful to employees within 2M around
