Embodiment 1

[0030] In related technologies, metal punching tools are usually used to set holes for rubber pulling on metal products. The metal punching tools use the principle of metal stamping to punch out holes on metal products. However, the holes set in this way have the following defect:

[0031] 1. The hole wall is smooth and the glue pulling force is not strong, which is prone to the problem of separation of plastic materials and metal products, which reduces the reliability of metal-plastic combined products;

[0032] 2. Since the holes are set by the metal punching tool, in order to ensure the strength of the metal punching tool, the metal punching tool should not be too thin, for example, the diameter of the metal punching tool should not be less than 0.5mm; this results in punched holes The diameter of the hole is greater than 0.5mm; in this case, if the diameter of the plastic injected into the hole is less than 0.5mm, after the metal-plastic combination product is applied to ...

Embodiment 2

[0051] This embodiment provides a metal product. In some examples, the so-called metal product may be a hardware product. The "hardware product" in this embodiment refers to a product made of gold, silver, copper, iron, and tin alone or in combination. In this example, if Figure 5 and Figure 6 ( Figure 5 shows a top view of the metal product 50, while Figure 6 shown Figure 5 As shown in the schematic cross-sectional view of the metal product 50 along AA'), the metal product 50 includes at least one hole 51, which is used to accommodate the plastic material flowing into it during the injection molding stage, and the plastic material in the inflow hole is solidified Finally, the combination of the plastic material and the metal product is realized, that is, the hole is a hole for pulling glue. Therefore, the metal product is a raw material for manufacturing metal-plastic combined products.

[0052] In this embodiment, the hole 51 on the metal product 50 is set with a ...

Abstract

The invention provides a metal product punching method, a metal product, a metal plastic combined product and a terminal. The metal product punching method comprises the steps that a to-be-punched meta product is placed on a laser punching workbench, and a punching strategy aimed at the metal product is confirmed; and then, a laser source on the laser punching workbench is adopted to punch the metal product according to the punching strategy, at least one hole formed through the method is used for accommodating a plastic material flowing into the hole in an injection molding stage, and after the plastic material is cured, the plastic material and the metal product are combined. According to the metal product punching method, the hole which combines the metal product with the plastic material is formed through the laser source, so that relative to holes formed through hardware punching, the hole has the advantage that the hole wall is more rough, after the plastic material is cured in the hole, adhesive force of the hole is higher, the plastic iron separation probability is reduced, and reliability of the metal plastic combined product is improved.

Description

technical field [0001] The invention relates to the technical field of terminals, in particular to a method for setting holes in metal products, metal products, metal-plastic combined products and terminals. Background technique [0002] In the terminal, it is usually necessary to use a plastic-iron integrated frame to fix and accommodate other components. For example, in the backlight module, an outer frame is required to accommodate components such as reflective film, LED light source, and light guide plate. Metal-plastic combination products such as plastic-iron integrated frames include metal parts and plastic parts. The plastic parts and metal parts are combined through the holes on the metal parts: through injection molding into the holes, after the plastic material in the holes is cured and formed , which can make the plastic part and the metal part tightly combined. The quality of the holes on the metal part will affect the firmness of the combination of the metal p...
