Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit boards, and more specifically, to a PCB circuit board for a new energy vehicle onboard OBC power supply. Background Technology
[0002] With the accelerated pace of global 5G communication infrastructure construction, the demand for high-multilayer circuit boards is surging. To ensure the alignment between layers in high-multilayer circuits, OPE punching machines are commonly used to punch alignment and riveting holes after the inner layer circuits are etched. OPE punching machines have visual positioning detection, and their punching efficiency is high, producing 8 riveting holes in one pass, with punching repeatability controllable within + / -1mil. However, after the PCB circuitry is completed, OPE punching requires manual placement of the board into the machine, with the board cursor positioned within the OPE punching window (8*8mm). This manual placement and alignment is extremely inefficient. Furthermore, since the OPE punching position is fixed, if the worker places the board in the wrong direction, it will lead to incorrect punching positions, causing incorrect orientation during multilayer board riveting, incorrect inner layer patterns, and irreparable losses. The low efficiency of OPE punching and the lack of error-proofing for the punching placement direction are pressing technical problems that need to be solved in this field. Utility Model Content
[0003] The purpose of this utility model is to provide a PCB circuit board for a new energy vehicle OBC power supply, which aims to solve the technical problem of incorrect hole placement during OPE punching in the prior art.
[0004] This utility model provides a PCB circuit board for the OBC power supply of new energy vehicles.
[0005] The circuit board includes a multi-layer unit board, and the multi-layer unit board is fixed together by rivets in riveting holes. The feature is that each unit board includes at least one opening position of riveting hole, and the surface of the unit board is provided with at least one direction indicator mark and at least two target marks, the target marks including a first target mark and a second target mark.
[0006] The first target point includes a first rectangular border, a first circular area within the first rectangular border, and a first graphic area located within the first circular area; the first graphic area is a copper-free area, and there is a metal solder joint between the first graphic area and the first circular area; there is a copper-plated area between the first circular area and the first rectangular border.
[0007] The second target point includes a second rectangular area, a second circular area set within the second rectangular area, the second circular area being a copper-free area, and a copper-plated area between the second circular area and the second rectangular area;
[0008] The first graphic area is located at the center of the first rectangular area and the first circular area; the second circular area is located at the center of the second rectangular area.
[0009] The PCB circuit board disclosed in this utility model is placed in a specific direction according to the directional indicators on the unit board when it enters the OPE punching equipment. The OPE punching equipment punches holes according to the preset punching positions, which are the opening positions in this application, thereby forming riveting holes. Even if the placement direction is incorrect, when the unit board enters the OPE punching equipment, two different marking targets set on the single board unit are used to identify and locate it, thereby determining the placement direction and position before punching. The PCB circuit board of this application achieves directional positioning by setting directional indicators and at least two different and easily identifiable marking targets, thus overcoming the technical problem in the prior art where incorrect placement leads to the scrapping of multilayer circuit boards. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the PCB circuit board structure of this utility model;
[0011] Figure 2 and Figure 3 This is a partial enlarged view of the PCB circuit board of this utility model. Detailed Implementation
[0012] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:
[0013] Please refer to Figures 1 to 3 This utility model provides a PCB circuit board 100 for a power supply for an onboard OBC in a new energy vehicle: it includes a multi-layer unit board 10, and the multi-layer unit boards are fixed together by rivets in the riveting holes 11.
[0014] Each unit plate 10 includes an opening position 12 for at least one riveting hole 11. The surface of the unit plate 10 is provided with at least one direction indicator mark 13 and at least two target marks 14, the target marks 14 including a first target mark 141 and a second target mark 142.
[0015] The first target point 141 includes a first rectangular border 141a, a first circular region 141b disposed within the first rectangular border 141a, and a first graphic region 141c located within the first circular region 141b; the first graphic region 141c is a copper-free region, and a metal solder joint is located between the first graphic region 141c and the first circular region 141b; the area between the first circular region 141b and the first rectangular border 141a is a copper-plated region.
[0016] The second target point 142 includes a second rectangular region 412a and a second circular region 142b disposed within the second rectangular region 412a. The second circular region 142b is a copper-free region, and the area between the second circular region 142b and the second rectangular region 142a is a copper-plated region.
[0017] The first graphic area 141c is located at the center of the first rectangular area 141a and the first circular area 141b; the second circular area 142b is located at the center of the second rectangular area 141a.
[0018] The PCB circuit board disclosed in this utility model is placed in a specific direction according to the directional indicators on the unit board when it enters the OPE punching equipment. The OPE punching equipment punches holes according to the preset punching positions, which are the opening positions in this application, thereby forming riveting holes. Even if the placement direction is incorrect, when the unit board enters the OPE punching equipment, two different marking targets set on the single board unit are used to identify and locate it, thereby determining the placement direction and position before punching. The PCB circuit board of this application achieves directional positioning by setting directional indicators and at least two different and easily identifiable marking targets, thus overcoming the technical problem in the prior art where incorrect placement leads to the scrapping of multilayer circuit boards.
[0019] In this application, the PCB circuit board includes a cutting area 15 disposed at the edge, and two marking targets 14 are disposed within the cutting area 15. Both marking targets 14 are located in the cutting area 15, and are located on both sides of the PCB circuit board 100.
[0020] After the multi-layer unit board 10 is fixed by the riveting holes 11 after punching and pressing, the area to be cut can be cut by the cutting tool to form a PCB board. Setting the target point and direction indicator mark in the area to be cut can prevent the finished functional area located inside the area to be cut from being affected.
[0021] The dimensions of the two marked target points are 5-8mm*10-12mm; the diameter of the first graphic area is between 1-1.3mm, and the diameter of the second circular area is between 1-1.3mm.
[0022] In this application, both target points are rectangular structures. However, one target point has a first circular area, while the other target point does not. With this setting, when the OPE punching equipment recognizes the pattern, it is easier to first identify the position of the corresponding target point, and then further identify whether the target point is the first target point or the second target point. The recognition efficiency is high and the accuracy is also high.
[0023] In this application, there are multiple opening positions 12, all of which are located in the cutting area 15, and the multiple opening positions 12 are spaced apart. This spaced arrangement can improve the uniformity of the multilayer board pressing and fixing.
[0024] Wherein, at least one of the first circular regions 141b in the first target point 141 coincides with at least one of the opening positions 12.
[0025] In this application, the size of the first circular region 141b is basically consistent with the position of the riveting hole 11 to be opened at the opening position 12. When the opening position is opened, the first circular region is punched out, so as not to affect the riveting structure at the riveting hole position.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
