Description

Plug assembling process

Technical Field

The invention relates to the electronic industry, in particular to a PCB wiring and shell mounting process.

Background

The electronics industry is never a technology-intensive, but labor-intensive, industry. The through hole mounting technology is the foundation of the electronic industry, and the tin surface inspection technology is always the foundation of the Chinese electronic industry. From the technical development trend of electronic components in the world, chip type has become one of the important signs for measuring the technical development level of electronic components in general, wherein three passive components, namely a chip inductor, a chip resistor and a chip inductor, account for about 85% -90% of the total output of the components. Electronic components are rapidly miniaturized while being made into chips, and the steps of electronic component combination and integration are accelerated along with the acceleration of the miniaturization process of electronic equipment. Because the electronic component products are of various types, each classified product has own characteristics in the technical development trend.

After various electronic components are welded on the PCB of the plug, working procedures such as wiring and shell mounting are needed, and defective products cannot be found in time in the conventional operation mode, so that the production efficiency is low. Therefore, there is a need for an improved plug assembly process to meet the current stage production requirements to improve production efficiency.

Disclosure of Invention

The invention aims to provide a plug assembling process to improve the working efficiency of plug assembling.

In order to achieve the above object, the present invention provides a plug assembling process, comprising the steps of:

step 1, taking down a semi-finished product processed in the last station from a conveyor belt by an operator with the left hand and lightly placing the semi-finished product on a workbench;

step 2, checking whether the work of the workstation is complete and in place, and starting the next work after confirming that no errors exist;

step 3, dividing the double handles 4 of the operator into single plates, and enabling the DC wire to pass through the bottom of the rubber shell by the right hand;

step 4, inserting and welding the DC wire into the hole at the corresponding position of the PCB by an operator, welding the wire end of the DC wire and fixing the DC wire on the corresponding bonding pad of the PCB;

and 5, after the operation is finished, the operator checks the operation by himself, and the operation flows to the next working procedure after the operation is qualified.

Preferably, in the plug assembling process, an operator must wear the electrostatic ring to work, and the electrostatic ring and the electrostatic wire are reliably connected.

Preferably, in the step 3, the operator needs to gently hold the rubber shell during operation, so that the appearance of the rubber shell cannot be damaged;

preferably, in the step 4, the DC line is soldered at the "V-" position of the PCB with the black line, the DC line is soldered at the "V +" position of the PCB with the red line, the soldering iron temperature is controlled at 360 ℃ ± 10 ℃, and the soldering time cannot exceed 3 seconds.

Preferably, in step 5, the operator checks and confirms that the solder joint has no defects such as empty solder, insufficient solder, continuous solder, cracked solder, and the like.

Detailed Description

The invention is mainly used for a PCB wiring and shell mounting process, and provides a plug assembling process which comprises the following specific steps:

step 1, in the plug assembling process, an operator needs to wear the electrostatic ring for operation and ensures reliable connection between the electrostatic ring and the electrostatic wire, and the operator takes down a semi-finished product processed in the previous station from the conveyor belt by the left hand and puts the semi-finished product on a workbench lightly.

And 2, checking whether the work of the workstation is complete or not, and starting the next work after the correctness is confirmed.

And 3, the operator needs to lightly hold the DC wire rod when operating, the appearance of the rubber shell cannot be damaged, the 4 connecting plates are divided into single plates by two hands, and the DC wire rod is held by the right hand and penetrates through the bottom of the rubber shell.

Step 4, inserting and welding the DC wire into the hole at the corresponding position of the PCB by an operator, welding the wire end of the DC wire and fixing the DC wire on the corresponding bonding pad of the PCB; and welding the DC wire at the V-position of the PCB by using the black wire, welding the DC wire at the V +' position of the PCB by using the red wire, and controlling the soldering iron temperature to be 360 +/-10 ℃ and ensuring that the welding time can not exceed 3 seconds.

And 5, after the operation is finished, an operator needs to check and confirm that the welding spot has no bad conditions such as empty solder, insufficient solder, continuous solder, cracked solder and the like, the welding spot flows to a next working procedure after the welding spot is qualified, and the defective products are placed at the designated positions.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
