Description

Technical Field

[0001] The utility model relates to the technical field of PCB processing jigs, in particular to a PCB board surface processing carrier. Background Art

[0002] A PCB is a substrate with electronic components and circuit patterns printed on its surface. It is made of insulating materials, usually glass fiber reinforced epoxy resin and other materials. PCB is a very common component in electronic devices and is used to support and connect various electronic components such as integrated circuits, resistors, capacitors and other electronic devices.

[0003] In the processing process of LED display modules, the PCB board needs to be placed in a spraying jig, and then the jig is placed on a support platform to spray an ink layer or a transparent layer and other structures on it. However, the PCB board of the LED display module is heated during the previous welding process of the LED chip and the driver IC, which will cause a certain degree of warping, resulting in the thickness of the ink layer sprayed on the surface of the PCB board being affected, thereby affecting the ink color difference and the display effect of the LED display after splicing. Utility Model Content

[0004] The utility model aims to provide a PCB board surface processing carrier which can correct the PCB board and make the ink color sprayed on the surface uniform.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A PCB surface processing carrier comprises a workbench, wherein two empty areas are provided on the surface of the workbench, a spraying fixture corresponding to the two empty areas is arranged at the bottom of the workbench, a pressing plate is arranged on the upper side of the workbench, first fixing blocks are installed on both sides of the pressing plate, a first guide rod is connected to the lower side of the end of the first fixing block, and the end of the first guide rod passes through the lower side of the workbench, a first spring is sleeved on the outer surface of the first guide rod, and the two ends of the first spring are respectively abutted against the first fixing block and the workbench, the lower ends of the two first guide rods are commonly connected to a cross plate, and a pedal is installed on the outer surface of the cross plate.

[0007] It can be seen that by placing the PCB board on the upper surface of the workbench and in the empty area, and then stepping on the pedal with the foot to drive the pressure plate to press on the PCB board, the PCB board can be pressed and leveled from all sides, and finally sprayed with a spraying fixture, thereby improving the consistency of the ink color sprayed on the PCB board and improving the display effect of the LED display after splicing. In addition, the staff can control the force of stepping on the pedal according to the warping degree of the PCB board to ensure that all PCB boards can be leveled, which is more practical. The pedal is installed on the lower side of the workbench through the first guide rod, and the overall structure is compact and the manufacturing cost is low.

[0008] Furthermore, right-angle limit blocks are installed at the four corners of the upper surface of the workbench located in the empty area.

[0009] By setting the right-angle limit block, the PCB board can be positioned, so that the staff can quickly and accurately place the PCB board in the processing position, and the area of ​​the PCB board to be sprayed can be in the empty area, thereby improving work efficiency.

[0010] Furthermore, a second fixed block is installed on the side of the pressure plate away from the pedal board, a second guide rod is connected to the lower side of the end of the second fixed block, and the end of the second guide rod passes through the lower side of the workbench, a connecting plate is installed on the end of the second guide rod, and the end of the connecting plate is connected to the cross plate.

[0011] By setting the second fixing block, the second guide rod and the connecting plate, the pressing plate can be limited in multiple directions, so that when the staff steps down on the pedal, the pressing plate can remain horizontal and stable, thereby improving the leveling effect of the PCB board.

[0012] Furthermore, grooves are provided at the four corners of the upper surface of the workbench in the empty area, a telescopic rod is installed inside the groove, a top plate is installed at the end of the telescopic rod, a second spring is sleeved on the outer surface of the telescopic rod, and the two ends of the second spring are respectively abutted against the top plate and the inner wall of the groove, and the highest point of the top plate is lower than the highest point of the right-angle limit block.

[0013] When the PCB board is placed between the four right-angle limit blocks and on the upper side of the four top plates, as the pressure plate presses the PCB board, the top plate can be retracted into the groove and be on the same plane as the surface of the workbench. When the PCB board is sprayed, the pedal is released, the first spring drives the pressure plate to reset upward, and under the elastic force of the second spring, the top plate can be pushed to lift the PCB board, so that there is a gap between the PCB board and the surface of the workbench, and the staff can put their fingers into the gap to quickly take out the PCB board.

[0014] Furthermore, support columns are installed at the four corners of the bottom of the workbench, and anti-slip pads are installed at the bottom of the support columns.

[0015] The structure of the processing platform can be made more stable by providing support columns and anti-slip pads.

[0016] Furthermore, a rubber pad is provided at the bottom of the pressing plate.

[0017] The rubber pad has a certain deformation ability, so when the pressure plate presses the PCB board, it plays a role of buffer protection to avoid damage to the PCB board. BRIEF DESCRIPTION OF THE DRAWINGS
