One-by-one bi-directional feeding device for PCBs

Abstract

The invention relates to the technical field of PCB assembly, in particular to a one-by-one bi-directional feeding device for PCBs. The one-by-one bi-directional feeding device comprises a base plate and two board separating assemblies. Each board separating assembly comprises an installation plate installed on the base plate, and multiple board supporting blocks are arranged on the inner sides of the installation plates at intervals. A pushing plate and a board separation driving mechanism are installed on the upper edge of each installation plate. The pushing plates are provided with multiple extending teeth, and each extending tooth is located in the interval between every two adjacent board supporting blocks. Conveying assemblies are installed on the inner sides of the installation plates and lower than the bearing faces of the board supporting blocks, and baffles are arranged above the board supporting blocks. The bi-directional feeding device can be used for feeding materials to two different machining devices through bi-directional feeding, so that investment cost for a production line is greatly reduced; feeding stability is high, mutual friction between the adjacent PCBs can be effectively avoided, the rejection rate of electronic products is effectively decreased, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of PCB board assembly, in particular to a PCB board-by-bidirectional feeding device. Background technique [0002] With the rapid development of electronic technology, the use of electronic products is becoming more and more extensive. PCB circuit boards are important components of electronic products, and most PCB circuit boards are completed through SMT production lines. Although there are independent supporting equipment related to SMT production lines such as automatic board feeding machine, board receiving machine, board storage machine and connecting table on the market, their functions are single and the volume is large, and customers need to plan a large space for placement , and it is necessary to purchase multiple devices with different functions to meet production needs, which lacks flexibility in actual production applications.

Although there are independent supporting equipment related to SMT production lines such as automatic board feeding machine, board receiving machine, board storage machine and connecting table on the market, their functions are single and the volume is large, and customers need to plan a large space for placement , and it is necessary to purchase multiple devices with different functions to meet production needs, which lacks flexibility in actual production applications

[0003] In addition, the existing PCB board one-by-one feeding equipment generally adopts the structure of the material box and the manipulator. The structure is relatively complicated and the manufacturing cost is relatively high. It is difficult for the general conventional production line to bear such a high cost. There are also baffles and conveyor belts on the market. However, the separation of PCB boards depends on the friction between the PCB board and the conveyor belt. At the same time, adjacent PCB boards will also rub against each other, causing the PCB board to damage the circuit due to friction, or the PCB board The friction between the conveyor belt and the adjacent PCB boards is smaller than that between the adjacent PCB boards, resulting in the failure of PCB board feeding and obvious defects
