Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PCB board processing, in particular to a processing system for PCB boards. Background Art
[0002] The Chinese name of PCB board is printed circuit board, also known as printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing technology, it is called a "printed" circuit board. In the production process of PCB board, it needs to be polished to ensure the smoothness of the PCB board.
[0003] Existing PCB board polishing equipment cannot protect the PCB board well, so the PCB board is easily shifted during the polishing process and damaged after polishing, thereby increasing production costs. In addition, only one PCB board can be processed separately during polishing. After completion, the PCB board needs to be removed and another PCB board needs to be fixed, which reduces work efficiency. Utility Model Content
[0004] The utility model aims to provide a processing device for PCB which has a protection device and is easy to use.
[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.
[0006] A processing system for a PCB board comprises an operating table and a grinder, wherein a table leg is installed at the bottom of the operating table, a load-bearing plate is installed at the center position of the upper side of the operating table, a through hole is opened at the center position of the load-bearing plate, an adjustment component and a grinder are arranged on one side of the load-bearing plate, the adjustment component is connected with the grinder through a mounting frame, and the adjustment component is used for lifting and lowering the grinder; a rotating component and a fixed component are arranged above the operating table, the rotating component is located at one side of the bottom of the load-bearing plate, and the fixed component is located at the center of the operating table, the rotating component is used for rotating and adjusting the load-bearing plate, and the fixed component is used for positioning a PCB board on the load-bearing plate; a control panel is arranged on one side of the operating table.
[0007] It can be seen that the PCB boards to be processed are placed on the load-bearing plate respectively, and the single-end fixation of multiple PCB boards is completed by using the fixing components to avoid the PCB boards being bent during fixation and affecting the grinding flatness, thereby improving the yield and reducing the production cost. After the PCB board is fixed, the lifting of the grinder can be adjusted to meet the needs of different heights by using the adjustment component, which is more applicable. After adjusting the height of the grinder, the grinder is started to process the PCB board. During the processing, different PCB boards can be moved to the bottom of the grinder by using the rotating component to drive the load-bearing plate to rotate. After processing the previous PCB board, there is no need to remove the PCB board and install another PCB board, thereby further improving the processing speed and achieving improved work efficiency. The fixing component is located at the center of the operating table, which is convenient for the circular arrangement of PCB boards, improves space utilization, and is conducive to the miniaturization of equipment.
[0008] Furthermore, the adjustment component includes an adjusting column, a screw, A bevel gear, a connecting rod, B bevel gear, B bevel gear, a first motor and a movable block, and an adjusting cavity is opened in the adjusting column; a screw is movably installed in the adjusting cavity, an A bevel gear is installed at the bottom of the screw, and a movable block is movably installed on the screw, and the movable block is connected to the grinder through a mounting frame; a connecting rod is movably installed on one side of the adjusting column through a mounting hole, a B bevel gear is installed at the inner end of the connecting rod located in the adjusting cavity, and the output connecting shaft of the first motor is connected to the outer end of the connecting rod located at the adjusting column; the B bevel gear and the A bevel gear are meshing.
[0009] During use, when the height of the grinder needs to be adjusted, the first motor is started to drive the B bevel gear to rotate, and the A bevel gear is driven to rotate under the action of gear meshing, thereby achieving the height adjustment of the grinder. By using the adjustment component to drive the grinder to adjust the height, it can adapt to different height requirements and meet the use of different types of PCB boards, with higher adaptability.
[0010] Furthermore, the rotating assembly includes a support column, a second motor, a driving gear and a driven gear; a support column is installed at the upper center of the operating table, the top of the support column is movably installed with the lower surface of the load-bearing plate through a mounting plate, and a driven gear is installed on the lower side of the load-bearing plate; a second motor is installed on the upper surface of the operating table, and the top of the output connection end of the second motor is connected to the driving gear, and the gears of the driving gear and the driven gear are meshed.
[0011] After the previous PCB board is processed, the second motor is started to drive the active gear to rotate, and the driven gear is driven to rotate under the meshing action of the gears, thereby driving the load-bearing plate to rotate. By using the rotating component, the next PCB board can be quickly moved to the bottom of the grinder for processing after the previous PCB board is processed, thereby avoiding the process of disassembling and installing the PCB boards for many times, reducing the processing time, and thus improving the overall processing efficiency.
[0012] Furthermore, the fixing assembly includes an electric push rod, an extrusion plate, an extrusion block and an extrusion spring, and an extrusion cavity is opened on the extrusion plate; an electric push rod is installed at the center position of the operating table, and the telescopic end of the electric push rod passes through the through hole on the load-bearing plate and extends to the top of the load-bearing plate; an extrusion block is installed in the extrusion cavity through an extrusion spring, one end of the extrusion spring is connected to the inner wall of the extrusion cavity, and the other end of the extrusion spring is connected to the surface of the extrusion block; the bottom of the extrusion block is connected to the end of the electric push rod located above the load-bearing plate.
[0013] When the PCB board needs to be fixed in position, the extrusion plate and the extrusion block are driven to move up and down by starting the electric push rod. Under the action of the extrusion spring and the extrusion block, the PCB board can be buffered during the extrusion process, thereby avoiding excessive extrusion of the PCB board under the extension and retraction action of the electric push rod, resulting in damage to the PCB board, reducing the loss of the PCB board, and thus avoiding an increase in production costs.
[0014] Furthermore, friction plates are equidistantly installed on the load-bearing plate.
[0015] By installing a friction plate on the load-bearing plate, the friction between the PCB and the load-bearing plate can be increased, and the PCB can be prevented from being offset during processing.
[0016] Furthermore, the control panel is provided with a display screen for displaying the startup status of the device and a control button for controlling the startup of the device.
[0017] The status of the work can be viewed in real time through the display screen, and the progress of the work can be followed up in real time through the control buttons. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Specifically, the PCB boards to be processed are placed on the load-bearing plate 2 respectively, and the extrusion plate 62 is driven to rise and fall by starting the electric push rod 61 until the extrusion block 63 is in close contact with the PCB board to complete the extrusion and fixation of the PCB board.
