Description

Technical Field

[0001] This invention belongs to the field of welding position planning technology, and specifically relates to a welding position planning method, welding method and welding device for a wire mesh surfboard. Background Technology

[0002] To address the issue of traditional surfboards being bulky and inconvenient to transport, modern surfboards are made using ductile fabric. This process requires welding the ductile fabric to form the surfboard's shape. The precise placement of these welds significantly impacts the surfboard's quality. Traditional manual welding methods can lead to weld deviations, causing air leaks and compromising the surfboard's overall quality.

[0003] Therefore, based on the above technical problems, it is necessary to design a new method for planning the welding position, a welding method, and a welding device for fabric surfboard welding. Summary of the Invention

[0004] The purpose of this invention is to provide a method for planning the welding position of a brushed fabric surfboard, a welding method, and a welding apparatus.

[0005] To address the aforementioned technical problems, this invention provides a method for planning the welding positions of a brushed fabric surfboard, comprising:

[0006] Obtain the shape of the wire drawing fabric to be welded;

[0007] Cut the wire mesh according to its shape;

[0008] The final solder joints are formed on the segmented shape.

[0009] Furthermore, obtaining the shape of the wire drawing fabric to be welded includes:

[0010] Based on the shape of each surfboard, obtain the shape of each piece of fabric to be welded, and build a database based on the shapes of all the fabrics to be welded.

[0011] Furthermore, the segmentation based on the shape of the wire drawing fabric to be welded includes:

[0012] Based on the shape of the wire drawing cloth to be welded, obtain the vertex of the shape, and divide the shape into upper and lower parts according to the preset size. The upper part is the raised part, and the lower part is the flat part.

[0013] Furthermore, when the weld points of the wire-drawing cloth to be welded need to be set separately for the raised portion and the flat portion, the preset division distance is determined according to the preset dimensions. The shape of the wire-drawing cloth to be welded is placed vertically, and the highest point of this shape is the vertex. Starting from the vertex, the shape of the wire-drawing cloth to be welded is divided downwards at preset division distances. The distance from the dividing line to the vertex is equal to the preset division distance. The area above the dividing line is the raised portion, and the area below the dividing line is the flat portion; or

[0014] When the weld point of the wire drawing cloth to be welded does not need to be set separately from the curved part and the flat part, determine the vertex of the shape of the wire drawing cloth to be welded, use any distance as the dividing distance, and divide the shape of the wire drawing cloth to be welded by dividing it downwards at intervals from the vertex. The distance between the dividing line and the vertex is equal to the dividing distance. The part above the dividing line is the curved part, and the part below the dividing line is the flat part.

[0015] Furthermore, forming the final solder joint on the segmented shape includes:

[0016] When the welded wire cloth needs to have its raised part and flat part set separately for welding points, for the raised part, at each first preset welding distance on the vertical line between the vertex and the dividing line, the initial welding point is formed on the outline of the raised part on both sides of the vertical line.

[0017] For the planar portion, initial weld points are formed at intervals of a second preset welding distance along the contour of the planar portion.

[0018] Furthermore, when the wire drawing cloth to be welded does not require separate welding points for the raised part and the flat part, an initial welding point is formed on the contour of the flat part at intervals of a second preset welding distance, and this second preset welding distance is synchronized to the raised part so that an initial welding point is also formed on the contour of the raised part at intervals of a second preset welding distance.

[0019] Furthermore, the initial solder joint is moved inward by a preset compensation distance to form the final solder joint;

[0020] At the same height parallel to the dividing line, the final weld points on both sides of the center line of the shape of the fabric to be welded constitute a set of final weld points.

[0021] Secondly, the present invention also provides a welding method for a brushed fabric surfboard using the above-mentioned method for planning the welding position of the brushed fabric surfboard, comprising:

[0022] The final weld point location is output to the welding device;

[0023] The welding device welds the upper and lower layers of the fabric together according to the final weld point.

[0024] Furthermore, the upper and lower layers of the fabric in the planar section are completely overlapped, and the upper and lower layers of the fabric in the planar section are welded together according to the position of the final welding point in the planar section.

[0025] After the upper and lower layers of fabric in the flat section are welded together, the upper layer of fabric in the upturned section is stacked on the lower layer of fabric, and the upper layer of fabric has a margin, that is, the upper layer of fabric is larger than the lower layer of fabric. When welding the upturned section according to the final weld point, the travel of the upper layer of fabric after each weld is greater than the travel of the lower layer of fabric, and the margin of the upper layer of fabric is evenly distributed to the position of each weld point.

[0026] During the welding process, each weld involves simultaneously welding a set of final weld points on the upturned or flat portion.

[0027] Thirdly, the present invention also provides a welding apparatus for welding the upper and lower layers of the fabric using the above-described welding method for fabric surfboards.

[0028] The beneficial effects of this invention are that by obtaining the shape of the fabric to be welded; dividing the fabric according to its shape; and forming the final weld points on the divided shapes, the invention achieves precise determination of the welding position. Through precise welding position, the fabric can be precisely welded, ensuring the quality of the fabric surfboard.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] like Figures 1 to 4 As shown, this embodiment 1 provides a method for planning the welding position of a brushed fabric surfboard, including: obtaining the shape of the brushed fabric to be welded; dividing the brushed fabric according to its shape; forming the final welding point on the divided shape; achieving precise determination of the welding position, and through precise welding position, the brushed fabric can be precisely welded, ensuring the quality of the brushed fabric surfboard.

[0039] In this embodiment, obtaining the shape of the wire drawing fabric to be welded includes: obtaining the shape of each wire drawing fabric to be welded based on the shape of each surfboard, and constructing a database based on the shapes of all the wire drawing fabrics to be welded; each shape can be imported and stored via a file, the importable file type being a standard DXF file or an XJD file provided by the software itself. Imported graphic elements or data are not subject to additional processing, meaning that users can customize graphic editing based on the imported file using the interactive functions provided by the software to meet the user's requirements for the processed graphic. Since the processable graphic requires continuous, closed polylines, if the user-imported DXF graphic data is invalid, this function can be used to select scattered sub-graphics and combine them into a complete polyline to complete subsequent processing operations. The combination into polyline function can be used in conjunction with the breakup function. When the input graphic is a block or other combined graphic, it can be first broken up and then combined into a polyline.

[0040] In this embodiment, the segmentation based on the shape of the wire drawing cloth to be welded includes: obtaining the vertex of the shape based on the shape of the wire drawing cloth to be welded, and dividing the shape into upper and lower parts according to a preset size, with the upper part being the raised part and the lower part being the flat part; alternatively, the lower part can be the raised part and the upper part the flat part; dividing a shape into the raised part and the flat part allows for the determination of welding points in the raised part and the flat part respectively, which facilitates the accurate determination of the welding point position.

[0041] In this embodiment, when the weld point of the wire-drawing cloth to be welded needs to be set separately for the raised portion and the flat portion, a preset division distance is determined according to a preset size. The shape of the wire-drawing cloth to be welded is placed vertically, and the highest point of the shape is the vertex. Starting from the vertex, the shape of the wire-drawing cloth to be welded is divided downwards at a preset division distance. The distance between the division line and the vertex is equal to the preset division distance. The area above the division line is the raised portion, and the area below the division line is the flat portion; or

[0042] When the welded wire mesh does not require separate welding points for the raised and flat parts, determine the vertex of the wire mesh shape. Using any distance as the dividing distance, divide the wire mesh shape downwards from the vertex at intervals. The distance from the dividing line to the vertex is equal to the dividing distance. The area above the dividing line is the raised part, and the area below the dividing line is the flat part. When the graphic size is large, the welding points for the raised part and the flat part can be separated, resulting in more welding points near the head of the raised part, making the head weld more secure during welding.

[0043] In this embodiment, forming the final weld points on the segmented shape includes: when the welded wire needs to have weld points set separately for the raised portion and the flat portion, for the raised portion, initial weld points are formed on the contour of the raised portion on both sides of the vertical line between the vertex and the dividing line at intervals of a first preset welding distance; for the flat portion, initial weld points are formed on the contour of the flat portion at intervals of a second preset welding distance; for example, when the shape is a half shape, the raised portion can have initial weld points set on the contour at a preset separation distance of 25mm, and the initial weld points are set more densely at the head position of the ellipse, which facilitates the firmness of subsequent welding; the initial weld points of the flat portion can be set directly on the contour of the flat portion with an arc length of 25mm.

[0044] In this embodiment, when the wire drawing cloth to be welded does not require separate welding points for the raised part and the flat part, an initial welding point is formed on the contour of the flat part at intervals of a second preset welding distance, and the second preset welding distance is synchronized to the raised part so that an initial welding point is also formed on the contour of the raised part at intervals of a second preset welding distance.

[0045] In this embodiment, the initial weld point is moved inward by a preset compensation distance to form the final weld point; at the same height parallel to the dividing line, the final weld points on both sides of the center line of the shape of the fabric to be welded are a set of final weld points; due to the size of the welding head of the welding device, the initial weld point is moved inward so that the welding device can ensure that the welding is on the fabric during welding, thus ensuring the strength of the weld.

[0046] Example 2

[0047] Based on Example 1, Example 2 further provides a welding method for a surfboard made of brushed fabric using the welding position planning method of Example 1, comprising: outputting the position of the final weld point into a welding device; welding the upper and lower layers of the brushed fabric according to the final weld point; and welding the brushed fabric into a surfboard.

[0048] In this embodiment, the upper and lower layers of the flat section's fabric are completely overlapped, and then welded together according to the position of the final weld point. After the upper and lower layers of the flat section are welded together, the upper layer of the curved section is placed on top of the lower layer, with an allowance on the upper layer (i.e., the upper layer is larger than the lower layer). When welding the curved section according to the final weld point, the upper layer travels more than the lower layer after each weld, and the allowance of the upper layer is evenly distributed to each weld point. During the welding process, each weld simultaneously welds a set of final weld points on either the curved section or the flat section. Different travel distances for the upper and lower layers can be achieved using a differential wheel. The allowance facilitates bending of the curved section, and the even distribution of the allowance to each final weld point prevents damage to the weld points during bending.

[0049] Example 3

[0050] Based on Embodiments 1 and 2, Embodiment 3 further provides a welding device for welding the upper and lower layers of the fabric using the above-described fabric welding method.

[0051] In summary, this invention achieves precise determination of the welding position by obtaining the shape of the fabric to be welded; dividing the fabric according to its shape; and forming the final welding points on the divided shapes. This precise welding position allows for accurate welding of the fabric, ensuring the quality of the fabric surfboard.
