Description

Technical Field

[0001] The invention relates to the technical field of communication card manufacturing, in particular to a punching line measuring device for a communication card. Background Art

[0002] Before using the communication card, the small card with the communication chip needs to be peeled off from the card body. In order to facilitate the user to easily peel off the small card, a peeling groove is usually punched out on the outer edge of the small card during the card body manufacturing process.

[0003] Considering the relative position error between the punching equipment and the card body, a special quality inspection process is required to measure the distance between the outermost punching line of the stripping groove and the edge or point on the card body, and then determine whether the distance is greater than the minimum allowable distance. Some punching lines need to be less than the maximum allowable distance. Qualified products are those in which the stripping groove and its punching line are limited to a specific area on the card body. Since the shape of the small card is a pentagon similar to a missing corner rectangle, there are five effective punching lines that need to be measured, namely the first punching line, the second punching line, the third punching line, the fourth punching line and the fifth punching line. Figure 1 , wherein it is necessary to measure the distance between the first punching line 31 and the third punching line 33 and the first reference edge 36, the distance between the second punching line 32 and the fifth punching line 35 and the second reference edge 37, and the distance between the fourth punching line 34 and the intersection of the first reference edge 36 and the second reference edge 37.

[0004] At present, a ruler is usually used to measure the distance from each punching line to the edge or point. The measurement personnel fix the card body to be measured on the table, and then use the zero scale line of the ruler to approach the edge of the card body, and then measure the distance of each punching line. In this process, it is necessary to ensure that the distance from the edge of the card body to the punching line is vertical, and the measurement must be slowly aligned. The measurement is time-consuming and prone to large errors. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a communication card punching line measuring device, which is simple to operate and can measure quickly and accurately.

[0006] According to an embodiment of the present invention, a device for measuring the punching line of a communication card comprises: a base; an upper cover, which is distributed above and below the base and connected to each other, and a slot for inserting a card body is formed between the upper cover and the base; a plurality of positioning cylinders, which are horizontally arranged in two rows at the edge of the slot, and the axis of each positioning cylinder extends in the up-down direction, and each row of the positioning cylinders has at least two positioning cylinders, wherein the outer common tangent line of one row of the positioning cylinders close to the slot constitutes a first positioning line, and the outer common tangent line of the other row of the positioning cylinders close to the slot constitutes a second positioning line, and the first positioning line and the second positioning line are perpendicular to each other; a marking frame, which is formed on the upper cover, and the marking frame is surrounded by the first marking line, the second marking line, the third marking line, the fourth marking line and the fifth marking line in sequence. The first marking line is parallel to the first positioning line, and the distance between the two is the minimum allowable distance between the first punching line and the first reference edge, the second marking line is parallel to the second positioning line, and the distance between the two is the minimum allowable distance between the second punching line and the second reference edge, the third marking line is parallel to the first positioning line, and the distance between the two is the maximum allowable distance between the third punching line and the first reference edge, the distance from the fourth marking line to the intersection of the first positioning line and the second positioning line is the maximum allowable distance from the fourth punching line to the intersection of the first reference edge and the second reference edge, and the fifth marking line is parallel to the second positioning line, and the distance between the two is the maximum allowable distance from the fifth punching line to the second reference edge.

[0007] At least the following beneficial effects are achieved: the measuring device cleverly designs the position and size of the marking frame so that each marking line of the marking frame is at the limit position, so as to compare each punching line on the card body, thereby being able to detect whether the card body product is qualified. The measuring device is easy to operate. It only needs to insert the card body into the slot so that the first reference edge and the second reference edge on the card body are respectively against the two rows of positioning cylinders, and then determine whether the first punching line, the second punching line, the third punching line, the fourth punching line and the fifth punching line on the card body are beyond the marking frame. In other words, as long as the first punching line, the second punching line, the third punching line, the fourth punching line and the fifth punching line on the card body are all in the marking frame, then the card body product is a qualified product and can be directly observed. Such measurement is very fast. In addition, the design of the positioning cylinder can ensure accurate positioning, and can prevent the situation where debris blocks the card body and causes inaccurate positioning, and the measurement accuracy is high.

[0028] In the description of the present invention, if there is a description of the first, second, third, fourth and fifth, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the sequence of the indicated technical features.

[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] Reference Figures 2 to 6 The present invention discloses a device for measuring the punching line of a communication card, comprising a base 1, an upper cover 2, a marking frame 8 and a plurality of positioning cylinders 5.

[0031] Reference Figure 2 and Figure 3 The upper cover 2 and the base 1 are distributed up and down and connected to each other. A slot 4 is formed between the upper cover 2 and the base 1. The slot 4 is suitable for the card body 3 to be inserted.

[0032] like Figure 2 As shown, multiple positioning cylinders 5 are horizontally arranged in two rows at the edge of the slot 4, and the axis of each positioning cylinder 5 extends in the up-down direction. Each row of positioning cylinders 5 has at least two positioning cylinders 5, and the outer circumference of one row of positioning cylinders 5 is close to the outer tangent line of the slot 4 to form a first positioning line 6, and the outer circumference of the other row of positioning cylinders 5 is close to the outer tangent line of the slot 4 to form a second positioning line 7, and the first positioning line 6 and the second positioning line 7 are perpendicular to each other.

[0033] It can be understood that the first positioning line 6 and the second positioning line 7 are both located in the slot 4. When the first reference edge 36 and the second reference edge 37 on the card body 3 respectively abut against the outer circumference of the two rows of positioning cylinders 5, the first positioning line 6 and the second positioning line 7 coincide with the first reference edge 36 and the second reference edge 37 respectively, and play a positioning role. The design of the positioning cylinder 5 can ensure precise positioning. Since the first reference edge 36 and the second reference edge 37 are both in point contact with the outer circumference of the positioning cylinder 5, compared to line contact, even if there are small debris in the slot 4, it will not affect the first reference edge 36 and the second reference edge 37 contacting the outer circumference of the positioning cylinder 5, which can prevent the occurrence of debris blocking the card body 3 and causing inaccurate positioning, and the measurement accuracy is high.

[0034] Reference Figure 2 and Figure 6 The marking frame 8 is formed on the upper cover, and the marking frame 8 is enclosed by a first marking line 81, a second marking line 82, a third marking line 83, a fourth marking line 84 and a fifth marking line 85 in sequence.

[0035] Further references Figure 1 and Figure 4 The first marking line 81 is parallel to the first positioning line 6 and the distance between the two is the minimum allowable distance between the first punching line 31 and the first reference edge 36 .

[0036] The second marking line 82 is parallel to the second positioning line 7 , and the distance between the second marking line 82 and the second positioning line 7 is the minimum allowable distance between the second punching line 32 and the second reference edge 37 .

[0037] The third marking line 83 is parallel to the first positioning line 6 , and the distance between the third marking line 83 and the first positioning line 6 is the maximum allowable distance between the third punching line 33 and the first reference edge 36 .

[0038] The distance from the fourth marking line 84 to the intersection of the first positioning line 6 and the second positioning line 7 is the maximum allowable distance from the fourth punching line 34 to the intersection of the first reference edge 36 and the second reference edge 37 .

[0039] The fifth marking line 85 is parallel to the second positioning line 7 , and the distance between the fifth marking line 85 and the second positioning line 7 is the maximum allowable distance from the fifth punching line 35 to the second reference edge 37 .

[0040] The present invention cleverly designs the position and size of the marking frame 8 on the upper cover 2 so that each marking line of the marking frame 8 is at an extreme position, so as to compare each punching line on the card body 3, thereby being able to detect whether the card body 3 product is qualified.

[0041] The measuring device is easy to operate. It only needs to insert the card body 3 into the slot 4 so that the first reference edge 36 and the second reference edge 37 on the card body 3 are respectively against the two rows of positioning cylinders 5, and then determine whether the first punching line 31, the second punching line 32, the third punching line 33, the fourth punching line 34 and the fifth punching line 35 on the card body 3 are beyond the marking frame 8. In other words, as long as the first punching line 31, the second punching line 32, the third punching line 33, the fourth punching line 34 and the fifth punching line 35 on the card body 3 are all within the marking frame 8, then the card body 3 product is a qualified product and can be directly observed. The measurement is very fast.

[0042] In some embodiments of the present invention, the marking frame 8 is printed on the bottom of the upper cover 2 and can be dyed black. The upper cover 2 is transparent and can be made of glass so that the operator can clearly observe the marking frame 8 through the upper cover 2.

[0043] The base 1 and the upper cover 2 can be connected by fasteners outside the slot 4, or by positioning the cylinder 5. In some embodiments of the present invention, refer to Figure 3 , Figure 5 and Figure 6 The base 1 and the upper cover 2 fit together in the area outside the slot 4 , the positioning cylinder 5 partially extends into the slot 4 and partially is located outside the slot 4 , and the base 1 and the upper cover 2 are connected through the positioning cylinder 5 .

[0044] Reference Figure 3 and Figure 6 The upper cover 2 is provided with a first embedded hole 21 at a position corresponding to the positioning cylinder 5, and the upper end of the positioning cylinder 5 is embedded in the first embedded hole 21. The upper cover 2 is provided with a first mounting hole 22 above the first embedded hole 21. The first mounting hole 22 and the first embedded hole 21 are connected to each other and penetrate the upper cover 2 from top to bottom. The inner diameter of the first mounting hole 22 is smaller than the inner diameter of the first embedded hole 21. The upper end of the positioning cylinder 5 is correspondingly provided with a first threaded hole, and the positioning cylinder 5 is connected to the upper cover 2 by means of a bolt passing through the first mounting hole 22 and connecting the first threaded hole.

[0045] Reference Figure 3 and Figure 5The base 1 is provided with a second embedded hole 11 at a position corresponding to the positioning cylinder 5, and the lower end of the positioning cylinder 5 is embedded in the second embedded hole 11. The base 1 is provided with a second mounting hole 12 below the second embedded hole 11. The second embedded hole 11 and the second mounting hole 12 are connected to each other and pass through the base 1 up and down. The inner diameter of the second mounting hole 12 is smaller than the inner diameter of the second embedded hole 11. The lower end of the positioning cylinder 5 is correspondingly provided with a second threaded hole, and the positioning cylinder 5 is connected to the base 1 by a bolt passing through the second mounting hole 12 and connecting the second threaded hole.

[0046] In some embodiments of the present invention, each row of positioning cylinders 5 is provided with two positioning cylinders 5, and two positioning cylinders 5 are sufficient to achieve accurate positioning of the card body 3, which is also conducive to making the measuring device into a smaller size. At the same time, the two positioning cylinders 5 in the same row can also be relatively far apart, eliminating the situation where the position of the card body 3 is deflected when the card body 3 is placed, thereby reducing the positioning error.

[0047] In order to facilitate the placement of the card body 3, the height of the slot 4 is greater than the thickness of the card body 3. Figure 4 The horizontal projection area of ​​the slot 4 is smaller than the area of ​​the card body 3 , and the card body 3 can be quickly inserted into or taken out of the slot 4 .

[0048] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
