Problems solved by technology

[0005] In the second procedure, the shielding cover is attached to the PCB. The positioning and inspection links in the steps need to be manually checked and confirmed. If the direction is wrong during the process, it will take time and effort to repair, which will seriously affect the production efficiency.
In addition, it is difficult to check the mounting direction of the shielding cover of the PCB, especially for the symmetrical shape, it is even more difficult to judge

Embodiment 1

[0042] figure 1 Embodiment 1 of the PCB shielding cover mounting method of the present invention is disclosed, including:

[0043] Step S1: Mount the shield on the PCB;

[0044] Step S2: identifying the correspondence between the preset first identifier on the PCB and the preset second identifier on the shield;

[0045] Step S3: judging whether the identified correspondence is consistent with the preset correspondence between the first identifier and the second identifier, if they are consistent, the placement is completed, if not, an alarm message is issued.

[0046] The PCB shield mounting method and system of the present invention can effectively identify the corresponding relationship between the preset first identifier on the PCB and the preset second identifier on the shield, and judge the identified correspondence and Whether the preset corresponding relationship is consistent, if it is consistent, the placement will be completed, if not, an alarm message will be issued...

[0048] figure 2 Embodiment 2 of the shielding cover mounting method of the PCB of the present invention is disclosed, including:

[0049] Step S1: Mount the shield on the PCB;

[0050] Step S2: identifying the correspondence between the preset first identifier on the PCB and the preset second identifier on the shield;

[0051] Step S3: judging whether the identified correspondence is consistent with the preset correspondence between the first identifier and the second identifier, if they are consistent, the placement is completed, and if they are inconsistent, an alarm message is issued;

[0052] Step S4: When it is judged that the identified correspondence is inconsistent with the preset correspondence between the first identifier and the second identifier, recycle the PCB on which the shielding case is mounted.

[0053] Compared with the first embodiment, the PCB shielding cover mounting method disclosed in the second embodiment is convenient to collect and centrally proc...

Abstract

The invention discloses a PCB shielding cover mounting method and system and a PCB and shielding cover mounting assembly. The PCB shielding cover mounting method comprises the following steps: S1) mounting a shielding cover on a PCB; S2) identifying the correspondence relation between a preset first identifier on the PCB and a preset second identifier on the shielding cover; and S3) judging whether the identified correspondence relation is identical to the correspondence relation between the preset first identifier and the preset second identifier, if so, finishing mounting, and if not, sending an alarm message. The invention also discloses a PCB shielding cover mounting system, which comprises a mounting mechanism, an identification module, a judgment module electrically connected with the identification module and an alarm module electrically connected with the judgment module. The PCB shielding cover mounting method and system are easy to operate and high in efficiency, and can effectively detect the PCB having the shielding cover and not meeting requirements, so that production efficiency of the PCB is further improved, and the yield of the obtained the PCB having the shielding cover is high.

Description

technical field [0001] The invention relates to the field of PCB production, in particular to a mounting method and system for a PCB shielding case, and a mounting assembly of a PCB and a shielding case. Background technique [0002] The shielding cover is a metal cover that can prevent electromagnetic interference and shield the components on the PCB (Printed Circuit Board, printed circuit board). The shielding cover isolates two spatial regions to control the induction and radiation of electromagnetic waves from one region to another. [0003] Shields are widely used in electronic products. With the miniaturization of electronic products and the diversification of functions, the shape and size of the shielding case are also becoming more and more diverse and complex. Due to the uncertainty of the product shape and PCB layout of the shielding can, most of the shielding cans are custom-made. [0004] In the SMT (SurfaceMountTechnology, surface mount technology) link of PC...
