An automatic move plug-in components spring touch button installation theory of operation:

firstly, completing the spring 50 by a spring robot, and making the bottom surface of the spring 50 into a bottom 52 or/and a top 51 which are planar;

secondly, punching the processed copper sheet into a fixing support 60 with three fixing pins and a limiting pin, and then performing a rolling procedure on the positioning support;

after the spring 50 is electroplated, the spring 50 uses a vibration disc to convey spring materials, the fixed support 60 is sent out by a braiding device, the spring 50 and the fixed support 60 are sent to a fixed stamping clamp for automatic assembly, and the spring 50 and the fixed support 60 are fixed by a crimping device after automatic assembly;

and fourthly, completing the braiding process through braiding equipment, and realizing automatic plug-in through an AI machine of a PCB factory.

The working principle of the braider is as follows: after the electric and pneumatic connection of the braid packaging machine, if the braid packaging machine is used for heat packaging, the cutter is raised to the proper temperature, and the carrier band and the air pressure of an air source are adjusted. The SMD components are placed into the carrier tape by manual or automatic feeding equipment, the motor rotates to pull the carrier tape forming carrier tape to a packaging position, the carrier tape is placed at the upper position, the two blades heated are pressed on the cover tape and the planting tape after the carrier tape is placed at the lower position, and the SMD component port on the carrier tape is sealed by the cover tape, so that the purpose of packaging the SMD components is achieved. The take-up reel then takes up the encapsulated carrier tape.

Some braiders are not hot sealed, but cold sealed. The cold seal of the stomach can lead the cover tape and the carrier tape to be bonded together without heating, and the cover tape used at the moment is sticky. Before packaging, the tape typically passes through two SENSORs, one for counting and one for material control. The material control is to detect whether there is a missing component in the carrier tape. If a miss is detected, the motor of the braider is immediately stopped and does not rotate, while the cutter head is also brought to the upper position. Counting SENSOR is typically done with optical fibers and requires a fast response so that counting is not missed. The counting SENSOR can count the side holes of the carrier tape or the molding grooves. The number of side holes is converted into the correct number of SMD.

AI machine, automatic plug-in components machine promptly, automatic plug-in components machine divides: the device comprises a cross-line component inserter, an axial component inserter and a radial component inserter. The different plug-in mechanisms are different. A circuit system: the automatic component inserter belongs to electromechanical integrated high-precision equipment, various functions of the automatic component inserter are uniformly coordinated and controlled by an internal CPU, and an action report result is fed back by a photoelectric switch or a Hall element or a sensing element such as a code.

The AI machine includes the gas circuit system: the automatic correction system comprises a pneumatic mechanism for each part, an X-Y positioning system (with a working clamp), a plug-in head assembly, a bending and shearing anvil block, an automatic correction system and a global plug-in machine, wherein the loosening and TDK are used for capturing a camera, an automatic board collecting and releasing system, a sequencer and element stack, an element detector and a centering correction system. The automatic plug-in components are installed on the PCBA in a motor integrated mode, the automatic plug-in components are all other plug-in components, namely components capable of being installed by the automatic plug-in components, the components basically comprise other plug-in components, such as components, capacitors, inductors and connector grades, engineering personnel in a design procedure can divide work on plug-in components of each station according to workload and rationality, each machine is only responsible for installing a plurality of components, the same operation is repeated, and the error opportunity is reduced as much as possible. When all the plug-ins to be mounted are mounted on the PCBA, a special station is responsible for conveying the PCBA to a W/S (wave soldering) grabbing chain, and meanwhile, solder blocks are pressed on some easily heated tilting plug-ins to prevent poor soldering. The W/S (wave soldering) is a soldering machine in which there is a melting tin furnace and the whole apparatus also has different heating pipes to control the temperature, i.e. to preheat. The W/S (wave soldering) is mainly used for soldering the components with the exposed components and the back patch. The PCBA enters the equipment, then passes through a spray head for spraying the soldering flux to clean the back, and then enters the tin furnace, and after the PCBA exits the tin furnace, an air knife thoroughly blows away residual tin from the plate. Since the tin in the tin furnace is wavy, the equipment is called wave soldering, and the soldered PCBA is taken out along the chain for the next process. Such as packaging processes and the like.
