Description

Technical Field

[0001] This utility model belongs to the field of PCBA processing technology, and more specifically, it relates to an automatic feeding and positioning device for PCBA micro-components. Background Technology

[0002] With the rapid development of electronic devices towards miniaturization and high integration, the application of micro-components in printed circuit boards (PCBAs) is becoming increasingly widespread. In the process of PCB manufacturing, a feeding device is usually required to position and feed the micro-components.

[0003] According to application number CN202322842861.1, a PCBA feeding device relates to the field of PCBA processing technology. The device includes a support frame with symmetrically arranged adjustment plates on its upper side. A connecting plate is connected to one side of the support frame via a telescopic rod. A push block is fixedly connected to the top of the connecting plate, and a push plate is fixedly connected to one side of the push block, with the push plate telescopically extending and retracting on the surface of the support frame. A rotating block is rotatably arranged on one side of the support frame, and material conveying components are arranged on all four sides of the rotating block. In this invention, by setting a rotating block on one side of the support frame, the square shape of the rotating block's side allows it to rotate, driving the PCBA boards on its surface to rotate, facilitating angled rotation feeding of the PCBA boards and increasing the device's practicality. Simultaneously, by setting material conveying components on the outside of the rotating block, the PCBA boards on the rotating block's surface can be synchronously conveyed after rotation, ensuring the device's feeding efficiency. Furthermore, the device has a simple structure and low maintenance costs.

[0004] Based on the above, the existing automatic feeding and positioning device for PCBA micro-components has a fixed structure for the vibratory feeder and feed bar, which makes it difficult to quickly adapt to micro-components of different specifications. When changing the type of component, the machine needs to be stopped, disassembled and the feed bar needs to be readjusted, which is time-consuming and affects production efficiency.

[0010] Furthermore, the replacement mechanism also includes: an adjustment slot, a pressing block, and an adjustment insert; the adjustment slot is located inside the fixed rod; the pressing block is slidably connected to the inside of the fixed base; the adjustment insert is fixedly connected to the outside of the pressing block, and the adjustment insert is slidably connected to the adjustment slot.

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

[0014] This invention facilitates the replacement of the feed rod through the design of a replacement mechanism. When feeding PCBA micro-components of different sizes, simply push the pressing block. The pressing block will cause the adjusting block to insert into the adjusting slot. At this time, the fixing rod, under the sliding connection between the adjusting block and the adjusting slot, will cause the limiting block to slide downward, disengaging it from the limiting slot. Then, pulling the feed rod will disengage the mounting slider from the mounting groove, thus completing the disassembly and replacement of the feed rod, improving work efficiency and reducing labor intensity. The adjustment mechanism also allows for the adjustment of the feed rod 7. When feeding PCBA micro-components of different sizes, the operating knob can be rotated. The rotation of the operating knob will... The rotating worm gear, in conjunction with the adjusting worm wheel, drives the threaded cylinder to rotate. The rotation of the threaded cylinder, through its threaded connection with the connecting threaded rod, causes the adjusting plate to slide, thereby adjusting the width of the material channel within the feed rod to accommodate different sized PCBA micro-components. Meanwhile, the hinge plate, under the action of a torsion spring, rests against the inner side of the vibratory feeder's feed tray, similarly accommodating different sized PCBA micro-components, effectively improving the equipment's adaptability. Through this mechanism, convenient feed rod replacement is achieved, improving work efficiency and reducing labor intensity, while precise adjustment of the feed rod is realized to accommodate different sized PCBA micro-components, significantly enhancing the equipment's applicability.
