Description

Technical Field

[0001] This utility model belongs to the field of electronic manufacturing technology, and more specifically, it relates to PCBA automatic spraying equipment without rinsing. Background Technology

[0002] Electronic components require cutting, welding, and spraying during processing. After welding, PCBAs need to be rinse-free to ensure they can proceed directly to subsequent manufacturing processes without cleaning. This process requires the use of automatic spraying equipment. The components are placed on the automatic spraying equipment's mounting base, and the equipment automatically processes them according to a pre-set program.

[0003] According to CN202420537282.8, this utility model discloses an automatic conformal coating machine for PCBA boards, relating to the field of conformal coating technology. It includes a stepper conveyor and an automatic coating machine mounted on the upper surface of the stepper conveyor. A fixed frame is mounted on the left side of the automatic coating machine on the upper surface of the stepper conveyor, and a positioning mechanism is provided outside the fixed frame. Compared with existing ordinary automatic conformal coating machines for PCBA boards, this automatic conformal coating machine allows operators to simply place the PCBA board roughly on the stepper conveyor, which then transports it to the designated position on the automatic coating machine for spraying. If the size of the PCBA board changes, the locking screw can be loosened, and the sliding adjustment limit rod can be slid to allow it to conform to the PCBA board for positioning. During positioning, rubber rollers reduce friction when the positioning plate is in contact with the board. The design of the roller groove and screw facilitates the disassembly and replacement of the rubber rollers.

[0004] Based on the above, existing automatic spraying equipment generally uses a rectangular placement plate structure to place the workpiece. The placement plate moves the workpiece for spraying. The placement plate is generally set parallel to the spraying equipment to facilitate uniform spraying of the workpiece. However, because the placement plate is parallel to the equipment, when the operator picks up the workpiece, they need to bend over to the placement plate to operate it. When working for a long time, this can easily lead to fatigue for the operator and affect their work efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a PCBA rinse-free automatic spraying device. This addresses the issue that existing automatic spraying devices typically use a rectangular placement plate to hold the workpiece, which then moves the workpiece for spraying. The placement plate is generally parallel to the spraying device to facilitate uniform spraying. However, because the placement plate is parallel, workers must bend over to reach the placement plate to handle the workpiece, leading to fatigue and reduced work efficiency over extended periods.

[0006] The purpose and effectiveness of this utility model PCBA rinse-free automatic spray coating equipment are achieved through the following specific technical means:
