Problems solved by technology

[0005] However, its process equipment is relatively complicated, requiring multiple compression cylinders, and when fixing the plastic part, the plastic part is divided into several parts, and several parts are positioned separately. Once a compression cylinder is in the wrong position during use, it will Damage to plastic parts will affect the relative position of plastic parts and metal parts

Embodiment 1

[0026] Such as figure 2 As shown, a thermal compression device includes a fixed pile, a plastic part installation part, and an iron part installation part; the plastic part installation part is set on the fixed pile (such as Figure 4 shown), and can be displaced along the height direction of the fixed pile; the upper end of the plastic part installation part is used to place the plastic part, and the fixed pile and the plastic part installation part together realize the positioning of the plastic part; the iron part installation part is used to place the iron part parts, and ensure that the side of the iron parts used to install the plastic parts is facing down. Specifically, the iron part installation part is magnetic on the side used to install the iron parts, and the iron parts are adsorbed on the iron part installation part. By controlling the iron parts The position of the magnetic part of the installation part can realize precise control of the relative position of the...

Embodiment 2

[0035] The difference with Embodiment 1 is that the mounting part of the iron part of the fixed pile is provided with a groove on one side for installing the iron part (such as image 3 shown), the iron piece is placed in the groove. The groove can realize the fixation of iron parts.

[0036] And when the iron part has an undercut, ensure that the width of the mounting part of the plastic part is smaller than the width of the plastic part,

[0037] The steps to use are:

[0038] Step 1: First place the plastic part on the plastic part installation part, the plastic part installation part and the fixing pile can realize the positioning of the plastic part;

[0039] Step 2: Install the iron parts on the iron part installation part, where there is a magnetic surface on the iron part installation part, and the iron parts are installed on the iron part installation part through magnetic adsorption; or the iron part installation part is used to install the iron parts There is a g...

Embodiment 3

[0045] The difference from Example 1 is that infrared lamps are provided around the upper end of the fixed pile to assist in heating the dispensing on the plastic parts to ensure that the dispensing glue is in a molten state. When in use, turn on the infrared lamp after dispensing on the surface of the plastic parts , Turn off the infrared lamp after the plastic part is in contact with the iron part.

Abstract

The invention belongs to a hot press fit mechanism, and particularly relates to a hot press fit device. The hot press fit device comprises a fixing pile, a plastic part mounting part and an iron part mounting part; the plastic part mounting part is arranged on the fixing pile in a sleeving manner, and can move in the height direction of the fixing pile, the upper end of the plastic part mounting part is used for containing of a plastic part, positioning of the plastic part can be jointly achieved through the fixing pile and the plastic part mounting part, the iron part mounting part is used for containing of an iron part, and it is ensured that the face, used for mounting of the plastic part, of the iron part is downward; the iron part mounting part is arranged above the fixing pile, and it is ensured that the plastic part can be accurately bonded on the iron part. The plastic part and the metal part can be more precisely fixed together.

Description

technical field [0001] The invention belongs to a thermocompression bonding mechanism, and in particular relates to a thermocompression bonding device. Background technique [0002] Such as figure 1 As shown, in the prior art, when a plastic part will be glued and fixed on an iron part, it must first be placed on the male mold surface of the iron part (ie figure 1 Dispens glue on the corresponding position on the side of the middle iron part facing downward), and then place the plastic part and the iron part on a positioning jig after dispensing glue, wherein the plastic part is located below the iron part, and pass A positioning bar fixes the plastic part and the iron part on the positioning jig, and the positioning jig is supported by a base. Afterwards, a pressing plate is preheated to 100-120 degrees and acts on the iron part, so that heat-conducting melt glue is generated between the iron part and the plastic part. After a period of time, the glue between the iron pa...
