Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of screening device especially relates to a copper sheet rapid screening board. BACKGROUND
[0002] In the copper sheet corrosion determination experiment, because the copper sheet is subjected to long-term polishing (corrosion wear) during the experiment, the length, width and thickness of the copper sheet gradually decrease, which can easily cause a series of adverse effects. For example, the reduction of the size of the copper sheet can directly affect the accuracy of the experimental data, because the calculation of the corrosion rate usually depends on the initial size of the copper sheet; at the same time, the reduction of the size of the copper sheet can change the contact area of the copper sheet and the corrosion medium, thereby affecting the uniformity and rate of the corrosion process; and long-term polishing can also easily introduce surface defects or change the microstructure of the copper sheet, further affecting the analysis and evaluation of the corrosion behavior. Therefore, when performing the copper sheet corrosion determination experiment, the size and surface state of the copper sheet should be strictly controlled and ensured to meet the experimental requirements. In addition, according to the requirements in the standard GB / T5096-2017, the size of the copper sheet participating in the corrosion determination experiment should be within the range of 75mm±5mm in length, 12.5mm±2mm in width and 1.5mm-3.0mm in thickness, and the copper sheet should be regularly inspected and the copper sheet meeting the standard size requirements should be screened out to ensure that the size and surface state of the copper sheet meet the experimental requirements.
[0003] The existing technology usually uses measuring tools to detect and screen out unqualified copper sheets, and the measuring tools are usually vernier calipers and graduated rulers. Obviously, although the measuring tool can effectively detect and screen out unqualified copper sheets, if the number of copper sheets to be screened is large, the worker needs to participate in reading frequently, which not only reduces the screening efficiency of the copper sheets, but also increases the labor intensity and time and effort of the worker, and the worker is prone to visual fatigue due to the dense scale lines after a long time of reading, which can easily lead to reading errors, thereby reducing the accuracy of the copper sheet size detection data and making it difficult to ensure the normal progress of the subsequent copper sheet corrosion determination experiment.

[0012] Beneficial effects:
[0013] 1. By overlapping the copper sheet rapid screening board and the copper sheet, the worker can intuitively view the size deviation of the copper sheet relative to the substrate, so as to estimate and judge whether the detected copper sheet is qualified, without using other measuring tools, which not only reduces the labor intensity of the worker, but also facilitates the detection and screening of the copper sheet in large quantities, saves time and effort, and improves the screening efficiency.

[0027] Embodiment 1:
[0028] The utility model provides a copper sheet rapid screening board.
[0029] In an embodiment of the utility model, a copper sheet rapid screening board includes a substrate 1, the length size of substrate 1 is 72mm, the width size is 11mm, the thickness size is 2mm, the bottom surface of substrate 1 is the first reference surface 2, and the two adjacent side surfaces of substrate 1 are the second reference surface 3 and the third reference surface 4 respectively.
[0030] Specifically, as Figures 1 to 4As shown in the copper sheet rapid screening plate, the length size of the substrate 1 is made as 72mm, the width size is made as 11mm, and the thickness size is made as 2mm, so that the size parameters of the substrate 1 meet the size requirements of the copper sheet 100 in the standard GB / T5096-2017; at the same time, according to the size requirements in the standard GB / T5096-2017, the length size of the substrate 1 in the actual manufacturing process is in the tolerance range of-2mm to +8mm, the width size is in the tolerance range of-0.5mm to +3.5mm, and the thickness size is in the tolerance range of-0.5 to +1mm, and then the larger tolerance range is used to facilitate the production of the substrate 1.
[0031] Further, the copper sheet rapid screening plate in the use process, by placing the substrate 1 horizontally on the external detection table, and making the first reference surface 2 on the substrate 1 and the table surface of the external detection table flat and fit, at the same time, the second reference surface 3 and the third reference surface 4 on the substrate 1 are respectively flat and fit with the external limiting structure (such as V-shaped block), so that the limiting placement of the substrate 1 can be completed; at the same time, when the substrate 1 is placed, the copper sheet 100 to be detected is overlapped and placed on the substrate 1, and the two adjacent sides of the copper sheet 100 abut against the external limiting structure, so that the worker can intuitively view the size deviation of the copper sheet 100 relative to the substrate 1, and judge whether the copper sheet 100 is qualified, that is, if the other two side walls of the copper sheet 100 are flush with the two side walls of the substrate 1, it means that the copper sheet 100 is qualified; otherwise, if the length size or the width size of the copper sheet 100 and the substrate 1 is too large, it means that the copper sheet 100 is unqualified. In addition, the worker can stably place the copper sheet 100 on the table surface of the external detection table, and compare the distance between the top surfaces of the copper sheet 100 and the substrate 1, so that the thickness size of the copper sheet 100 can be easily judged, which is simple in operation and convenient to use.
[0032] Obviously, by overlapping the copper sheet rapid screening plate of the utility model with the copper sheet 100, the worker can intuitively view the size deviation of the copper sheet 100 relative to the substrate 1, so that the worker can estimate and judge whether the detected copper sheet 100 is qualified, without using other measuring tools, which not only reduces the labor intensity of the worker, but also facilitates the detection and screening of the copper sheet 100 in large quantities, saves time and effort, and improves the screening efficiency; at the same time, the utility model replaces the reading operation by intuitive visual judgment, avoids the reading error caused by visual fatigue of the worker, improves the accuracy of screening, and ensures the normal progress of the copper sheet 100 corrosion determination experiment.
[0033] In an embodiment, the first limiting plate 5 is rotatably installed on the second reference surface 3, and the first limiting plate 5 is used to abut against a side wall of the copper sheet 100 along a width direction of the copper sheet 100. Specifically, as shown in Figures 1 to 3 the first limiting plate 5 and the base plate 1 can be rotatably connected by a threaded connection, so that the first limiting plate 5 is not only convenient to disassemble, replace, but also can rotate relative to the base, and the structure design is simple and reasonable. Further, when the copper sheet 100 needs to be detected and screened, the worker rotates the first limiting plate 5 and makes the first limiting plate 5 abut against the side wall of the copper sheet 100, so that the copper sheet 100 can be blocked and positioned in the width direction, without separately finding and using an additional external limiting structure, and the use is more convenient and fast. In addition, after the detection and screening are completed, the worker reversely screws the first limiting plate 5, and rotates the first limiting plate 5 as a whole into the second reference surface 3, so that the utility model is convenient to store.
[0034] In an embodiment, as shown in Figures 1 to 3 the number of the first limiting plate 5 is multiple, and the multiple first limiting plates 5 are arranged in the extension direction of the base plate 1, so that the copper sheet 100 can be blocked and positioned by multiple points through the multiple first limiting plates 5, and the placing stability of the copper sheet 100 on the base plate 1 is improved.
[0035] In an embodiment, the second limiting plate 6 is rotatably installed on the third reference surface 4, and the second limiting plate 6 is used to abut against a side wall of the copper sheet 100 along a length direction of the copper sheet 100. Specifically, as shown in Figures 1 to 4 the second limiting plate 6 and the base plate 1 can be rotatably connected by a threaded connection, so that the second limiting plate 6 is not only convenient to disassemble, replace, but also can rotate relative to the base, and the structure design is simple and reasonable. Further, when the copper sheet 100 needs to be detected and screened, the worker rotates the second limiting plate 6 and makes the second limiting plate 6 abut against the other side wall of the copper sheet 100, so that the copper sheet 100 can be blocked and positioned in the width direction, without separately finding and using an additional external limiting structure, and the use is more convenient and fast. In addition, after the detection and screening are completed, the worker reversely screws the second limiting plate 6, and rotates the second limiting plate 6 as a whole into the third reference surface 4, so that the utility model is convenient to store.
[0036] In an embodiment, as shown in Figure 1 , Figure 3 and Figure 4As shown, the distance from the end face of the first limiting plate 5 and the second limiting plate 6 away from the base plate 1 to the top surface of the base plate 1 is 1.5mm to 3mm. It can be understood that in the detection process of the copper sheet 100, the copper sheet 100 is placed on the base plate 1, and the worker can judge whether the length and width dimensions of the copper sheet 100 are qualified by checking the spacing deviation of the copper sheet 100 and the base in the length and width dimensions. Since the distance from the end face of the first limiting plate 5 and the second limiting plate 6 away from the base plate 1 to the top surface of the base plate 1 is 1.5mm to 3mm, according to the size requirements of the copper sheet 100 in the standard GB / T5096-2017, the thickness dimension of the copper sheet 100 is 1.5mm-3.0mm, so the worker can check the spacing deviation between the top surface of the copper sheet 100 and the end face of the first limiting plate 5 and the second limiting plate 6 away from the base plate 1, and thus can judge whether the thickness dimension of the copper sheet 100 is qualified, which is simple to operate and convenient to use.
[0037] In an embodiment, the second reference surface 3 and the opposite side wall thereof are formed with a minimum length scale line 7, the third reference surface 4 and the opposite side wall thereof are formed with a minimum width scale line 8, and the first limiting plate 5 and the second limiting plate 6 are respectively formed with a minimum thickness scale line 9. Figures 1 to 4 As shown, according to the size requirements of the copper sheet 100 in the standard GB / T5096-2017, the minimum length dimension of the copper sheet 100 participating in the corrosion determination experiment is 70mm, so the minimum length scale line 7 formed on the second reference surface 3 and the opposite side wall thereof is 70mm; similarly, the minimum width dimension of the copper sheet 100 participating in the corrosion determination experiment is 10.5mm, so the minimum width scale line 8 formed on the third reference surface 4 and the opposite side wall thereof is 10.5mm; and the minimum width dimension of the copper sheet 100 participating in the corrosion determination experiment is 1.5mm, so the minimum thickness scale line 9 formed on the first limiting plate 5 and the second limiting plate 6 is 1.5mm, thereby marking the various minimum limit dimensions of the copper sheet 100 on the base plate 1, so that the worker can judge whether the copper sheet 100 is qualified, and the accuracy of detection and screening is improved. It is worth noting that in the actual manufacturing process of the utility model, the various dimensions of the base plate 1 can be made as the maximum limit dimensions of the copper sheet 100, that is, according to the size requirements of the copper sheet 100 in the standard GB / T5096-2017, the various dimensions of the base plate 1 can be made as length 80mm, width 14.5mm, and thickness 3.0mm, so that the worker can intuitively check and judge whether the various dimensions of the detected copper sheet 100 exceed the maximum value in the standard range and affect the use, and the accuracy of screening is further improved.
[0038] In an embodiment, the bottom surface of the base plate 1 is provided with mounting seats 10 spaced apart along the extension direction thereof, and magnetic attraction members 11 are respectively embedded in the two mounting seats 10. Figure 1 andFigure 2 As shown, two mounting seats 10 are arranged on the bottom surface of the substrate 1 at intervals, so that the bottom surface of the substrate 1 can be separated from the placement plane at the preset position, so that the staff can take the utility model; meanwhile, the substrate 1 can be stably supported by the two mounting seats 10, thereby ensuring the stability of the utility model during the detection process. In addition, the magnetic attraction piece 11 can be embedded in the two mounting seats 10, and the magnetic attraction piece 11 can be a magnet in the prior art, so that the substrate 1 can be fixedly installed at the preset position to detect the copper sheet 100, thereby improving the installation stability of the utility model, and the structure design is simple and reasonable.
[0039] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various changes and modifications to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
