Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing technology, and more specifically, it relates to PCBA micro-component crimping and assembly tooling. Background Technology

[0002] In today's era of rapid development in electronic technology, electronic devices are constantly evolving towards miniaturization, lightweighting, and high integration. This trend has led to the increasingly widespread application of micro-surface mount components (SMCs) such as 0201 and 01005 in the manufacturing process of printed circuit board assemblies (PCBAs). These micro-components, with their advantages of small size and high performance, provide key support for the miniaturization and high performance of electronic devices. However, when dealing with these micro-components, many insurmountable problems are exposed. Manual soldering relies on the experience and skills of operators. In order to overcome the drawbacks of traditional processes and improve the assembly quality and efficiency of PCBA micro-components, using a press machine to crimp the circuit board has become a feasible and effective solution. The press machine can provide stable and controllable pressure, applying appropriate pressure between the micro-component and the circuit board pads, so that the solder can better fill the gap between the component and the pad under pressure, thereby forming a reliable electrical connection.

[0003] The existing application number is CN202011168208.6. This invention discloses a circuit board assembly fixture and its usage method suitable for vehicle navigation, relating to the field of circuit board assembly technology. The invention includes a frame assembly, a carrier assembly on the surface of the frame assembly, a pressure plate assembly at the upper end of the carrier assembly, and a top frame assembly at the upper end of the frame assembly. The frame assembly includes an assembly frame, with cooling vents on its surface. A storage box is fixedly installed on the side of the assembly frame near the cooling vents. An assembly groove is provided at the upper end of the assembly frame, and a support frame is fixedly installed at the bottom end of the assembly frame. This invention positions and places the printed circuit board onto a metal substrate. The weight of the counterweight causes the assembly pressure plate to press firmly against the printed circuit board, ensuring a tight fit between the printed circuit board and the metal substrate. This prevents solder paste from slowly cooling and overflowing onto the sides of the metal substrate and the printed circuit board, thus improving the assembly quality and efficiency of the circuit board assembly.

[0004] Based on the above, when crimping micro-components onto existing circuit boards, workers generally need to place the micro-components into the mounting position on the circuit board first, and then use a crimping machine to crimp the circuit board. However, due to the small size of the micro-components, workers may not be able to place them properly, which can cause the micro-components to fly off during crimping, posing a certain safety hazard. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a PCBA micro-component crimping assembly fixture. This fixture solves the problem that when crimping micro-components on existing circuit boards, workers typically need to place the micro-components into the mounting position on the circuit board first, and then use a crimping machine to crimp the circuit board. However, due to the small size of the micro-components, workers may not be able to place them properly, which can cause the micro-components to easily break off during crimping, posing a certain safety hazard.

[0006] The purpose and effectiveness of this PCBA micro-component crimping assembly fixture are achieved through the following specific technical means:

[0007] The PCBA micro-component crimping and assembly fixture includes a crimping machine body, a crimping fixed plate, a crimping movable plate, an assembly platform, a crimping cylinder, a crimping protective mechanism, and an assembly positioning mechanism.

The assembly platform is fixedly connected above the crimping movable plate. The crimping cylinder is fixedly connected to the upper inner part of the crimping machine body. The crimping protective mechanism is located on the outer side of the crimping movable plate. The assembly positioning mechanism is located above the assembly platform.

[0008] Furthermore, the press-fitting protection mechanism includes: a protection drive cylinder, a protection limiting slide groove, and a protection connecting slider; the protection drive cylinder is fixedly connected to the rear of the press-fitting machine body, and the front end of the piston rod of the protection drive cylinder is fixedly connected to the press-fitting moving plate; two sets of protection limiting slide grooves are provided, and the two sets of protection limiting slide grooves are respectively opened on the upper left and right sides of the press-fitting fixed plate; two sets of protection connecting sliders are provided, and the two sets of protection connecting sliders are respectively fixedly connected to the lower left and right sides of the press-fitting moving plate, and both sets of protection connecting sliders are slidably connected inside the protection limiting slide groove.

[0009] Furthermore, the pressing protection mechanism also includes: a first protective rack, a protective drive gear, a protective shield, and a second protective rack; two sets of the first protective rack are provided, and the two sets of first protective racks are respectively fixedly connected to the upper left and right sides of the pressing moving plate; two sets of the protective drive gear are provided, and the two sets of protective drive gears are respectively rotatably connected to the front left and right sides of the pressing fixed plate, and the two sets of protective drive gears respectively mesh with the first protective rack; the protective shield is slidably connected to the front of the pressing machine body; two sets of the second protective rack are provided, and the two sets of second protective racks are respectively fixedly connected to the rear left and right sides of the protective shield, and the two sets of second protective racks respectively mesh with the protective drive gear.

[0010] Furthermore, the assembly positioning mechanism includes: a supplementary lighting panel light; the supplementary lighting panel light is fixedly connected to the inner side of the assembly platform.

[0011] Furthermore, the assembly positioning mechanism also includes: positioning adjustment holes and positioning pins; multiple sets of positioning adjustment holes are provided, and each set of positioning adjustment holes is a threaded hole structure, and the multiple sets of positioning adjustment holes are respectively opened on the inner side of the assembly platform; two sets of positioning pins are provided, and the two sets of positioning pins are respectively threadedly connected to the upper part of the inner side of the positioning adjustment hole.

[0012] Furthermore, the assembly positioning mechanism also includes a lever cylinder; two sets of lever cylinders are provided, and the two sets of lever cylinders are respectively fixedly connected to the upper left and right sides of the press-fitting moving plate, and the upper end of the two sets of lever cylinders is provided with a lever pressure plate structure.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention, through the setting of a press-fit protection mechanism, opens the protective drive cylinder. The piston rod of the protective drive cylinder moves backward, causing the press-fit moving plate to move backward. The backward movement of the press-fit moving plate causes the first protective rack to move backward, which in turn causes the protective drive gear to rotate. The rotation of the protective drive gear causes the second protective rack to move downward, which in turn causes the protective shielding plate to move downward. The downward movement of the protective shielding plate effectively shields the press-fit area, preventing small components from flying out and protecting the workers. At the same time, after press-fitting is completed, the piston rod of the protective drive cylinder moves forward, causing the press-fit moving plate to move forward. The forward movement of the press-fit moving plate causes the assembly platform to move forward, making it easier for workers to pick up the assembled circuit boards. This achieves separation of the assembly area and the press-fitting area, thus protecting the workers.

[0015] This invention, through the assembly positioning mechanism, connects the positioning pins to the corresponding positioning adjustment holes according to the circuit board model. Then, the circuit board is inserted with the positioning pins, at which point the positioning pins position the circuit board. Then, the lever cylinder is opened, which clamps the circuit board, ensuring its stability during assembly. Finally, the supplementary light panel is turned on, and its light passes through the mounting holes of the circuit board, making it easier for workers to find the mounting positions of the pins of the micro-components and improving the assembly efficiency of the micro-components.

The rotation of the protective drive gear 105 causes the second protective rack 107 to move downward. The downward movement of the second protective rack 107 causes the protective shielding plate 106 to move downward.
