Description

Technical Field

[0001] The present invention relates to the technical field of circuit boards, and more particularly to a circuit board mounting device for smart home appliances. Background Art

[0002] The circuit board of smart home products is one of the core components of the smart home system. It undertakes the important function of controlling and connecting various smart devices. There are many types of circuit boards, among which hard-soft circuit boards are widely used in the field of smart homes. Hard-soft circuit boards are circuit boards with FPC and PCB characteristics formed by combining flexible circuit boards (FPC) and rigid circuit boards (PCB) through lamination and other processes according to relevant process requirements. In addition, according to the number of circuit layers, circuit boards can also be divided into single-sided circuit boards, double-sided circuit boards, multi-layer circuit boards, etc., and when installing them, it is necessary to select the installation device according to different circuit boards.

[0003] Chinese patent document (CN108788709B) discloses a circuit board installation device that can be installed quickly. The specification states that "it includes a box body and a positioning plate, a slide groove is provided on the surface of the positioning plate, a connecting shaft is passed through the interior of the slide groove, a triangle plate is fixedly connected to the top of the connecting shaft, and a right-angle plate is fixedly connected to the top of the triangle plate, and a baffle is fixedly connected to the surface of the connecting shaft and located below the positioning plate, which relates to the technical field of circuit boards. The circuit board installation device that can be installed quickly can use a first spring to pull two adjacent connecting sleeves toward the middle, that is, pull the triangle plate and the right-angle plate closer to the center, and then the circuit board can be clamped by the cooperation of the triangle plate and the right-angle plate, and the circuit board can be positioned by adjusting the elongation of the slide rod in the fixed sleeve and making the clamping block clamp the screw column, and can be directly aligned at the next installation without aligning the circuit board with the screw hole of the screw column. It is easy to use, faster to operate, and improves work efficiency." However, in actual use, it is still difficult to adjust the position of the screwdriver head of the installation device according to the size of the circuit board.

[0004] Existing circuit board installation devices mainly rely on cylinder-driven robotic arms to adjust the position of the screwdriver head so as to accurately align the mounting holes on the edge of the circuit board. However, given that current circuit boards generally adopt a standard rectangular or square design, and the positioning holes are usually set at the four corners of these boards, such a design puts forward special requirements for the installation process. Although the installation method using a robotic arm can achieve high-precision positioning and installation, the corresponding equipment cost is relatively high, which increases the burden of production and maintenance. On the other hand, if manual installation is adopted, it is not only time-consuming, but also inefficient, which seriously wastes human resources. Both methods have shortcomings in ensuring the efficiency of circuit board installation and the convenience of operation. In view of this, we propose a circuit board installation device for smart home appliances. Summary of the invention

[0027] Working principle: This embodiment provides a circuit board installation device for smart home appliances. When in use, the housing mechanism 1 is grasped to move the position of the device, and the adjustment mechanism 3 is adjusted accordingly according to the size of the circuit board, so that the installation mechanism 2 is aligned with the installation holes at the four corners of the circuit board, and then the circuit board can be installed through the installation mechanism 2; When adjusting the position of the installation component 203, the knob 308 is pulled upward, so that the telescopic component 302 is extended and misaligned with the protective component 303. At this time, the steel cable 309 loses its restriction, and the steel cable 309 outside the winding disk 306 is loosened. The rotating component 202 will push the installation component 203 to move in the slide slot 102 due to the loss of the restriction of the steel cable 309.

When the motor 2041 is running, the driving disk 2042 and the tooth block 2043 are driven to drive the transmission belt 2053 to move outside the transmission wheel. Since the four transmission belts 2053 are respectively engaged with the four gears 2025 through the tooth grooves 2054, the transmission belt 2053 will synchronously drive the four gears 2025 to rotate when moving.
