Description

Technical Field

[0001] This invention relates to the field of circuit board processing technology, and in particular to a waterproof encapsulation device for PCB circuit board production. Background Technology

[0002] In today's rapidly developing electronics and information industry, PCB circuit boards, as core components of electronic devices, operate in increasingly complex and diverse environments. Waterproofing performance has become a key indicator of PCB reliability. Especially in applications such as outdoor electronic equipment, industrial control devices, and automotive electronic systems, PCBs are constantly exposed to humid, dusty, or liquid-splashed environments. Inadequate waterproofing can easily lead to short circuits, component corrosion, and other malfunctions due to moisture intrusion, directly impacting the lifespan and operational stability of the equipment. Therefore, developing efficient and reliable waterproofing encapsulation devices for PCB circuit boards is of significant practical importance.

[0003] Currently, the industry primarily uses manual glue application or semi-automated equipment for waterproof encapsulation of PCB circuit boards. This makes it difficult to ensure uniform glue distribution, easily leading to problems such as incomplete or over-sealing, resulting in unstable waterproof performance. Furthermore, most waterproof encapsulations require mixing two or more glue ingredients in specific proportions. Existing equipment often has simple mixing mechanisms, relying solely on natural mixing during pipeline transport, which fails to achieve thorough and uniform glue fusion, directly impacting the strength of the encapsulated adhesive and its waterproof seal. The diverse specifications of PCB circuit boards and mounting boxes mean that the clamping components of existing equipment have poor adaptability, easily resulting in loosening or over-tightening during fixation, causing circuit board displacement during glue application and affecting the accuracy of the glue application position. Traditional equipment's glue application components often use fixed trajectory movement, making it difficult to adapt to the complex glue application requirements of different circuit board sizes. For irregularly shaped or multi-area encapsulated circuit boards, comprehensive coverage is often impossible.

[0004] Therefore, there is a need to design a waterproof encapsulation device for PCB circuit board production that can efficiently mix adhesives and accurately position PCB circuit boards and mounting boxes. Summary of the Invention

[0036] When waterproof encapsulation of a PCB circuit board is required, the circuit board is installed in the corresponding mounting box, and then the mounting box is placed on the square platform 10 and pushed backward. The mounting box presses the arc surface on the front side of the mounting shell 119, which causes the two mounting shells 119 to drive the sliding plate 113 to move backward. The slot 114 of the sliding plate 113 drives the two swing rods 116 to rotate around the fixed axis 115 through the sliding shaft 117. The elastic element 118 is compressed, and the mounting box is pushed into the two mounting shells 119. The roller 1110 can guide the outside of the mounting box. When the rear side wall of the mounting box abuts against the baffle 1111, the pushing of the mounting box stops. At this time, operated via control panel 3, motor 46 drives lead screw 45 to rotate, and lead screw 45 drives slider 42 to move forward on straight slide rail 41. When the dispensing head 71 is above the mounting shell 119, motor 46 stops working, and first cylinder 55 operates, which can drive first sliding block 54 to move left and right for position adjustment. Second cylinder 64 operates, which can drive second sliding block 63 and dispensing head 71 to move up and down for adjustment. Agitator 12 mixes the glue in glue tank 8, and then the air compressor in glue tank 8 operates, and compressed air enters glue tank 8. Glue enters mixing tube 73 through hose 75 and branch pipe 74. In mixing tube 73, the two glue raw materials are squeezed by vortex blades 92, which in turn drive... As the vortex blade 92 rotates, the adhesive, after being sprayed out through the mixing tube 73 into the dispensing head 71, undergoes further mixing. Through the coordinated movement of the Y-axis moving component 4, X-axis moving component 5, and Z-axis moving component 6, adhesive can be injected into various parts of the mounting box, thereby flooding the PCB circuit board and achieving a waterproof encapsulation effect. After encapsulation, the control panel 3 controls the dispensing component 7 to stop dispensing adhesive, and starts the third cylinder 131 to drive the push plate 132 to push the mounting box forward, disengaging it from the clamping component 11 and moving it to the position of the cover plate 16 on the square platform 10. The vibrator 17 at the bottom of the cover plate 16 works to drive the cover plate 16 and the mounting box to vibrate at high frequency, making the adhesive in the mounting box evenly vibrate. This device has a simple structure and is easy to operate.
