Example Embodiment

[0023] The present invention discloses a manufacturing process of an LED bracket with good air tightness, such as figure 1 As shown, it includes the following steps:

[0024] (1) Stamping: Use a press and a mold to form a metal bracket.

[0025] (2) Inspection: The metal bracket is inspected to sort out qualified and defective products. If the metal bracket is NG, then return to stamping; if the metal bracket is OK, then enter the next process. The inspection adopts the combination of first article inspection and inspection Way.

[0026] (3) Injection molding: Put the qualified metal bracket into an injection mold for injection molding to form an insulator, so that the metal bracket and the insulator are fixed together by insert molding.

[0027] (4) Inspection: Inspect the semi-finished product after injection to sort out qualified and defective products; if the semi-finished product is NG, return to continue injection molding; if the semi-finished product is OK, enter the next proc...

Abstract

The invention discloses a manufacturing technology of an LED bracket with good air-tightness. The manufacturing technology comprises the following steps of: (1) stamping, namely stamping and molding a metal bracket by a press machine and a mold in fit; (2) checking; (3) injection molding; (4) checking; (5) electroplating; (6) checking; (7) bending and cutting; (8) checking; (9) packaging; and (10) checking. The LED bracket is manufactured in a manner of electroplating after injection molding; and the metal bracket is coarse in surface after being stamped and molded and can be firmly combined with an insulator, so that the air-tightness of a product is ensured. Meanwhile, electroplating treatment is carried out after injection molding; and an electroplating material can carry out further sealing treatment on the combined edge of the insulator and the metal bracket, so that the air-tightness of the product is further improved. Furthermore, a clad layer is not polluted by an injection molding material, so that the usability of the product is effectively improved.

Description

technical field [0001] The invention relates to the technology in the field of LED brackets, in particular to a manufacturing process of an LED bracket with good airtightness. Background technique [0002] The LED bracket is a base electronic component and one of the important components of the LED package. It mainly provides mechanical bearing, support, airtight protection and heat dissipation for the LED chip and its interconnection, and promotes the heat dissipation of the LED device. In recent years, with the improvement of semiconductor materials and packaging technology, and the improvement of luminous flux and light output efficiency, power LEDs have been applied in special lighting fields such as urban landscapes, traffic signs, LCD backlights, automotive lighting, billboards, etc. The lighting market is moving forward. [0003] However, when the current LED bracket is made, the metal bracket is firstly electroplated, and then the electroplated metal bracket is put ...
