Embodiment 1

[0041] This embodiment provides a material detection method based on an LCR bridge, such as figure 1 and Figure 5 shown, including the following steps:

[0042] Step S10, the upper computer pre-stores several material tables and the corresponding testing specifications (testing configuration) of each material table; that is, each material truck of each factory line or each type of PCB board corresponds to a material table and a testing specification;

[0043] Step S20, after the host computer authenticates the user, it presents each material table to the user;

[0044] Step S30, based on the detection specification associated with the material list selected by the user, the host computer uses the LCR bridge to detect the material vehicle or PCB board to generate detection data based on the detection specification; the model of the LCR bridge is preferably TH2829; The upper computer communicates with the LCR bridge through RS232; the LCR bridge detects the PCB board through ...

Embodiment 2

[0053] This embodiment provides a material detection system based on an LCR bridge, such as figure 2 and Figure 5 As shown, the following modules are included:

[0054] The material table and inspection specification setting module is used for the upper computer to pre-store several material sheets and the inspection specifications (test configuration) corresponding to each material sheet; that is, each material truck of each factory line or each type of PCB board corresponds to a material sheet and 1. Testing specifications;

[0055] The identity authentication module is used for the upper computer to display the material list to the user after the user is authenticated by the host computer;

[0056] The material detection module is used for the upper computer to detect the corresponding detection specification based on the material list selected by the user, and based on the detection specification, use the LCR bridge to detect the material truck or PCB board to generate...

Embodiment 3

[0066] This embodiment provides a material detection device based on an LCR bridge, such as image 3 As shown, it includes a memory, a processor, and a computer program stored in the memory and operable on the processor. When the processor executes the computer program, any implementation manner in Embodiment 1 can be realized.

[0067] Since the electronic device introduced in this embodiment is the device used to implement the method in Embodiment 1 of this application, based on the method described in Embodiment 1 of this application, those skilled in the art can understand the electronic device of this embodiment. Specific implementation methods and various variations thereof, so how the electronic device implements the method in the embodiment of the present application will not be described in detail here. As long as a person skilled in the art implements the equipment used by the method in the embodiment of the present application, it all belongs to the protection scope...

Abstract

The invention provides a material detection method, system and equipment based on an LCR bridge and a medium in the technical field of electronic equipment production. The method comprises the following steps that S10, a plurality of material lists and detection specifications corresponding to the material lists are pre-stored in an upper computer; S20, after the upper computer carries out identity authentication on the user, each material list is displayed to the user; S30, the upper computer associates a corresponding detection specification based on the material list selected by the user, and detects the material vehicle or the PCB by using an LCR bridge to generate detection data based on the detection specification; and S40, the upper computer judges whether the materials of the material trolley or the PCB are correct or not based on the detection data. The method has the advantages that the material detection efficiency and quality are greatly improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic equipment production, in particular to a material detection method, system, equipment and medium based on an LCR bridge. Background technique [0002] The placement machine is also called the placement machine or the surface mount system. In the production line, the placement machine is configured after the dispensing machine or the screen printing machine, and the surface mount components are accurately placed on the PCB pad by moving the placement head. on a device. In the process of using the placement machine, the production personnel need to prepare materials (components) in advance. It is inevitable that there will be errors in the process of preparing materials, especially when the production line is replaced, resulting in defects in the produced products that need to be reworked. Therefore, in the product After the production is completed, the materials need to be tested to determine w...
