Description

Technical Field

[0002] During the traceability code processing of printed circuit boards, when the PCB board is transported from the previous process to the code drilling machine station through a conveyor line (roller or belt conveyor line), in order to ensure the position requirements of the processed traceability code on the PCB board, the PCB board needs to be positionally corrected before processing the traceability code to ensure the position accuracy of the traceability code on the PCB board.

[0003] Existing PCB positioning devices use a slap plate method: the PCB is transported by a line to a defined position (in the X-axis direction), whereupon a push plate or push rod of the slap plate positioning mechanism (Y-axis axial movement device) pushes the PCB to the defined Y-axis position to achieve right-angle positioning. However, when processing thin sheets less than 0.3 mm, this slap plate positioning method can cause warping and deformation of the sheet surface and edges due to the large thrust, affecting the processing quality of subsequent processes and even resulting in sheet scrapping. Furthermore, positioning accuracy is unstable. Utility Model Content

[0024] See also Figures 1 to 6, this embodiment provides a positioning device, including an X-axis axial movement positioning device 1 and a Y-axis axial movement positioning device 2, the X-axis axial movement positioning device 1 includes several groups of rolling components 101 distributed along the left and right sides, and the left or right sides of several groups of rolling components 101 are provided with X-axis blocking plates 102 that can block and position the plates to be positioned, and several groups of rolling components 101 can move the plates to be positioned along the left and right directions to the X-axis blocking plates 102; the Y-axis axial movement positioning device 2 includes several groups of conveyor belt components 201 distributed along the left and right sides, several groups of conveyor belt components 201 are spaced apart from several groups of rolling components 101 along the left and right directions, and the front or rear sides of several groups of conveyor belt components 201 are provided with Y-axis blocking plates 202 that can block and position the plates to be positioned, and several groups of conveyor belt components 201 can move the plates to be positioned along the front and rear directions to the Y-axis blocking plates 202. Function: (1) By including an X-axis axial movement positioning device and a Y-axis axial movement positioning device, the X-axis axial movement positioning device includes a plurality of rolling assemblies distributed along the left and right sides, an X-axis material stopper that can block and position the plate to be positioned is provided on the left or right sides of the plurality of rolling assemblies, and the plurality of rolling assemblies can move the plate to be positioned along the left and right directions to the X-axis material stopper; thereby, the plate to be positioned (such as a thin plate such as a PCB board) can be moved by the plurality of rolling assemblies and closely attached to the X-axis material stopper. (2) By including a Y-axis axial movement positioning device including a plurality of conveyor belt assemblies distributed along the left and right sides, the plurality of conveyor belt assemblies and the plurality of rolling assemblies are spaced apart along the left and right directions, a Y-axis material stopper that can block and position the plate to be positioned is provided on the front or rear sides of the plurality of conveyor belt assemblies, and the plurality of conveyor belt assemblies can move the plate to be positioned along the front and rear directions to the Y-axis material stopper; thereby, the plate to be positioned (such as a thin plate such as a PCB board) can be moved by the plurality of conveyor belt assemblies and closely attached to the Y-axis material stopper, thus completing the right-angle positioning action of the plate to be positioned (such as a thin plate such as a PCB board). From this analysis, we can see that the present invention can improve positioning accuracy.
