Description

Technical Field

[0001] The present invention relates to the technical field of cutting electronic accessories, and in particular to a method for optimizing the cutting process of a radio frequency antenna plate. Background Art

[0002] As we all know, with the improvement of production technology, especially in the field of electronic component production, the technology of RF antenna boards is updated and replaced relatively quickly. The 5G RF antenna boards currently used in various fields have relatively high requirements for internal circuit boards due to the particularity of the antenna boards. Therefore, the cutting technology requirements for the cutting of the antenna boards are relatively high. The existing 5G RF antenna boards are made of thinner halogen-free, high tg value plates. When cutting 5G RF antenna boards, the number of teeth of the tungsten steel V-CUT knife cannot be sparse. If the depth of the V-CUT is retained at 0.10-0.15MM, it is easy to break the board and V-pierce. Since the material of the 5G RF antenna board is also a halogen-free plate, the material is relatively brittle. If the speed of the V-CUT machine is too fast, it is easy to burst the edge during cutting. The bursting of the edge will also affect the signal reception of the RF antenna board, resulting in more defective products and further increasing the production cost. Therefore, a method is needed to reduce the bursting edge and optimize the cutting process of the RF antenna board. Summary of the invention

[0003] In view of this, an object of the present invention is to provide a method for reducing edge bursting during cutting of a radio frequency antenna board and optimizing the cutting process of the radio frequency antenna board.

[0004] In order to achieve the purpose of the present invention, the present invention provides a method for optimizing the cutting process of a radio frequency antenna plate, which specifically includes the following steps:

[0005] S1. Set the V-CUT knife of the V-CUT machine to a 30-40 tooth tungsten steel V-CUT knife;

[0006] S2. Set the unit of V-CUT knife to 20000cm;

[0009] S5. Set the cutting speed of the V-CUT machine to 45-50cm / min;

[0011] The thickness of the radio frequency antenna board is 0.40-0.60 mm, and the radio frequency antenna board is a high-halogen and high-tg value board.

[0013] Preferably, the V-CUT knife of the V-CUT machine is a 30-tooth tungsten steel V-CUT knife, and the angle of the tungsten steel V-CUT knife is 20°.

[0014] Preferably, the cutting speed of the V-CUT machine is 50 cm / min.

[0015] Preferably, in the step S3, when a single V-CUT direction is selected, the cutting mode of the X-axis is set to de-cutting, the offset value of the Y-axis is set to -0.05 mm, and the offset value of the X-axis is set to 0 mm.

[0022] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings.

[0023] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to another element and integrated therewith, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which they pertain. The terms used in the specification herein are intended only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1 As shown, a preferred embodiment of the present invention provides a method for optimizing a cutting process of a radio frequency antenna plate, which specifically includes the following steps:

[0026] S1. Set the V-CUT knife of the V-CUT machine to a 30-40 tooth tungsten steel V-CUT knife;

[0027] S2. Set the unit of V-CUT knife to 20000cm;

[0028] S3. Turn off the back and forth cutting function of the V-CUT machine and select a single V-CUT direction;

[0029] S4. Set the V-cut parameters of the V-CUT machine;

[0030] S5. Set the cutting speed of the V-CUT machine to 45-50cm / min;

[0031] S6. Cut the radio frequency antenna plate 1 on a V-CUT machine.

[0032] Because the RF antenna board 1 is not an antenna board of ordinary material, but a halogen-free board, the material is brittle, and specific cutting parameters need to be set. The RF antenna board is also a signal board. If the V-cut line has defects or cracked edges after cutting, it will also affect the signal reception of the RF antenna board. Selecting a single V-CUT direction is to ensure the consistency of the depth of the back and forth cutting and avoid the V-cut phenomenon after cutting. After the RF antenna board is cut on the V-CUT machine, it is necessary to check whether the V-cut line of the cut RF antenna board has cracked edges or defects.

[0033] refer to Figure 1As shown, in a further preferred embodiment, the RF antenna board 1 is generally 0.40-0.60 mm thick and is a high-halogen high-tg value board. The material of the RF antenna board 1 is different from that of a general circuit board. The material of the RF antenna board 1 is thinner and more brittle. If the cutting parameters of the V-CUT machine are not properly set during cutting, the board may break or V-piercing may occur easily.

[0034] refer to Figure 1 As shown, in a preferred embodiment, in step S4, when setting the V-engraving parameters, the X-axis removal parameter is set to 50mm / s. The X-axis removal parameter is a value adjusted after multiple tests. In this embodiment, the X-axis removal parameter is set to 50mm / s to prevent the edge from bursting due to excessive speed during cutting. The X-axis removal parameter is set to 50mm / s or below 50mm / , so that the V-engraving effect can meet the requirements. The X-axis return parameter is set to 600mm / s, the Y-axis removal parameter is set to 600mm / s, and the Y-axis return parameter is set to 600mm / s. By setting appropriate cutting parameters, it can be ensured that the edge bursting 3 defect on the V-engraved line is prevented during cutting, thereby reducing the defective rate.

[0035] refer to Figure 1 As shown, in the preferred embodiment, the V-CUT knife of the V-CUT machine is a 30-tooth tungsten steel V-CUT knife, and the angle of the tungsten steel V-CUT knife is 20°. When the tungsten steel V-CUT knife is selected for cutting, the line will not burn the board and turn black. Compared with the previous diamond V-CUT knife, because the material of the RF antenna board is thin, the tungsten steel V-CUT knife has good cutting performance and will not burn the board. The angle of the V-CUT knife is selected to be 20° because the angle of the 20° V-CUT knife is small, the tip of the knife will be sharper, and the material will not be burned. For thinner RF antenna boards, the cut surface is smaller when it contacts the board surface, which can effectively reduce the oil loss and edge bursting of the board surface. The number of teeth of the tungsten steel V-CUT knife cannot be less than 30 teeth. The 30-tooth tungsten steel knife has more teeth, and the blade surface is denser, which will form a denser cutting line surface. When contacting the RF antenna board, the contact cutting line area is denser, and it is not easy to have edge bursting 3 during cutting. If the number of teeth is too large, it will result in fewer teeth, smaller contact cutting line surface, gaps in the cutting line surface, and it is easy for the cutting surface to have edge bursting 3.

[0036] refer to Figure 1As shown, in the preferred embodiment, the cutting speed of the V-CUT machine is 50cm / min, and the normal cutting speed is 40cm / min. In this embodiment, the cutting speed of the V-CUT machine is 50cm per minute or less. The purpose is to prevent the V-line from bursting 3 due to excessive speed, and to ensure that the V-line 2 can meet the requirements each time it is cut, without affecting the signal receiving function of the RF antenna board, with a low defective rate and reduced board waste.

[0037] refer to Figure 1 As shown, in a preferred embodiment, in step S3, when a single V-CUT direction is selected, the cutting mode of the X-axis is set to de-cutting. Selecting a single V-CUT direction can ensure that the depth of the RF antenna board is the same when cutting back and forth, and it will not be deep on one side and shallow on the other side, resulting in different depths and failing to meet the V-line 2 requirement. The Y-axis offset value is set to -0.05mm, and the X-axis offset value is 0mm. The set values ​​are all for preventing the V-line from bursting and V-penetration, thereby improving the V-line compliance rate.

[0038] refer to Figure 1 As shown, in a preferred embodiment, in step S3, when a single V-CUT direction is selected, the cutting mode of the Y axis is set to pull cutting.

[0039] refer to Figure 1 As shown, in a preferred embodiment, the V-CUT machine is a high-precision automatic V-CUT machine. Because the RF antenna board itself is an antenna board made of relatively special materials, high precision is required when V-cutting. The high-precision automatic V-CUT machine has high precision requirements and is suitable for cutting 5G RF antenna boards. In this embodiment, the high-precision automatic V-CUT machine is already a prior art and will not be described in detail in this specification.

[0040] The beneficial effects of the present invention are as follows: the present invention provides a method for optimizing the cutting process of a radio frequency antenna board. In the method, the number of teeth of a tungsten steel V-CUT knife is set, a single V-CUT direction and a cutting speed of a V-CUT machine are set, which can effectively reduce the edge bursting and V-piercing phenomena of the radio frequency antenna board during cutting, reduce the ratio of defective products in the production process, further reduce the production cost expenditure, and improve production efficiency.
