Description

Technical Field

[0001] This utility model relates to the technology in the field of charging gun production, and in particular to a laser engraving machine for cutting and inspecting the outer shell of a charging gun. Background Technology

[0002] A charging gun is a device component used to charge electric vehicles or electric vehicle battery packs, typically in conjunction with charging stations or charging piles. The charging gun is designed to safely and efficiently transfer electrical energy to charge the electric vehicle's battery pack. It generally consists of a gun body, plug, cable, safety lock, and indicator lights / displays. When the charging gun is plugged into the electric vehicle's charging port, it establishes an electrical connection with the vehicle's charging system. The charging pile or charging station provides the necessary electrical energy, which is then transferred to the electric vehicle's battery pack via the charging gun. Internal electrical components within the charging gun monitor and control current and voltage to ensure the safety and efficiency of the charging process.

[0003] Typically, the gun body is formed by splicing two outer shells together. These two shells are generally molded using injection molding, and are symmetrically spliced ​​and fixed together to form a gun body. During the manufacturing process, after the outer shells are injection molded, they are usually connected with sprue gates. These sprue gates are relatively long and located in tricky positions. In current technology, the sprue gates can only be cut off manually. After the sprue gates are cut off, a logo is laser-engraved on the outer surface of the shell using a laser engraving device. This method has very low production efficiency, consumes a lot of manual labor, increases labor costs, and the cutting quality is inconsistent. Therefore, it is necessary to study a solution to the above problems. Utility Model Content

Then, the unloading robot 10m of injection molding machine m takes four charging gun shells l from the injection molding machine at once and puts them into the first receiving slot 101c of the first steering device c. After the electric gun housing l completes its turning in the first turning device c, it is transferred two at a time by the first robotic arm 40i corresponding to the transport and transfer device i into the coarse cutting device d.

Next, the first robot arm 40i corresponding to the transport and transfer device i transports and moves the two height-detected charging gun housings l into the second steering device g. Then, the two charging gun housings l are steered in the second steering device g. Finally, the first robot arm 40i corresponding to the transport and transfer device i moves the two charging gun housings l in the second steering device g. One by one, they are placed into the corresponding third receiving slot 101h in the rotary shifting device h. Then, the charging gun shell l rotates in the rotary shifting device h and passes through the laser engraving device j, the laser engraving detector 40h and the sorting and discharging device k in sequence. The laser engraving device j laser engraves the LOGO on the outer surface of the charging gun shell l. The laser engraving detector 40h detects the laser engraved LOGO on the outer surface of the charging gun shell l to determine whether the laser engraving is qualified. The sorting and discharging device k outputs the charging gun shell l that has completed the laser engraving test. During the output process, qualified products and defective products are discharged separately.
