Description

Technical Field

[0001] The utility model relates to the technical field of plastic packaging machines, in particular to a plastic packaging machine for processing circuit boards. Background Art

[0002] The circuit board is the core of electronic products. It can realize the integration of electronic modules. After processing, the circuit board needs to be plastic-sealed to protect the circuit board and facilitate subsequent storage, transportation and sales.

[0003] The current circuit board processing laminating machine, as described in the patent with announcement number CN218022554U, comprises a base and a laminating chamber, wherein the laminating chamber is fixedly mounted on one side of the top of the base, and a lifting cylinder is fixedly mounted on the top of the laminating chamber. The circuit board processing laminating machine places the circuit board to be laminating at a specified position on the carrier, and then starts the servo motor, which drives the gear to rotate at a constant speed. The gear pushes the sliding block through the rack, so that the sliding block slides horizontally and uniformly on the outside of the slide rail, thereby driving the carrier to enter the specified position inside the laminating chamber at a constant speed, and then the circuit board is sent to the specified position inside the laminating chamber. In this way, the circuit board can be automatically and accurately sent into the interior of the laminating chamber. Compared with the previous conveyor belt transportation, it is not easy to deflect, which ensures that the laminating can be accurately performed, and the phenomenon of laminating failure is avoided. It solves the problem that the positioning cannot be accurately performed, and thus the accurate laminating cannot be performed, and the phenomenon of laminating failure is easy to occur.

[0004] With respect to the above-mentioned related technologies, the applicant believes that although a plastic sealing machine for circuit board processing can improve the accuracy of moving the circuit board to the bottom of the plastic sealing device when in use, it is still a mobile product for plastic sealing. During the moving process, the circuit board will still move slightly, resulting in a decrease in the plastic sealing effect. After the circuit board is placed, the device needs to be moved, plastic sealed and cooled. The next circuit board can only be plastic sealed after the plastic sealing is completed, resulting in low efficiency in using the plastic sealing head, which affects the efficiency of circuit board plastic sealing production.
