Description

Technical Field

[0001] The present invention mainly relates to the technical field of glass cutting, and in particular to a method for improving a tool path for special-shaped cutting. Background Art

[0002] With the expansion of the application fields of liquid crystal display glass, it is widely used in various consumer electronics, home appliances, medical equipment and other fields, especially in the field of new energy vehicles in recent years. There are various product shape requirements, including regular squares and various special shapes. Among the special shapes, there are special shapes such as obtuse angles and acute angles.

[0003] The existing technology is to start the knife at the intersection of the glass and then drop the knife at the intersection. Due to the tolerance fluctuation of the tool path of the equipment itself, it is not ideal to make the starting and dropping points of the knife coincide at the intersection every time. There is a certain probability of non-coincidence risk. When the starting point and the dropping point of the knife cannot coincide, the intersection is prone to chipping. Therefore, the present invention provides a method for improving the tool path for special-shaped cutting to solve the above problem. Summary of the Invention

[0004] The present invention mainly provides a method for improving the tool path for special-shaped cutting to solve the technical problems raised in the above background technology.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: a method for improving the tool path for special-shaped cutting, comprising the following steps:

[0006] S1, fixing the glass body by a fixing device and determining the cutting path of the glass body;

[0007] S2, determining the starting point of the cutting tool on both sides of the cutting path, and determining the ending point of the cutting tool on both sides of the cutting path, and making the ending point and the starting point close to each other;

[0008] S3, the tool enters from the starting point on one side, cuts the glass along the cutting path, and moves out from the starting point on the other side;

[0009] S4, moving the tool to an adjacent cutting point, allowing the tool to enter from the cutting point and cut the glass body along the cutting path, and then allowing the tool to move out from another cutting point;

[0010] S5, taking down the cut glass body, fixing the uncut glass body, and making the cutter start cutting from the adjacent starting point.

[0011] Furthermore, in S1, the fixing device is an adsorption device, including an air pump and a cutting plate connected to the air pump through an air pipe, and the top of the cutting plate is connected to the glass body.

[0012] In the present invention, the air pump is used to enable the cutting plate to vacuum absorb the glass body, making it easier for the cutter to cut the glass body.

[0013] Furthermore, the glass body includes a waste area and a use area, and the waste area and the use area are separated by a cutting path.

[0014] Furthermore, in S2 and S3, the starting path of the tool entering the cutting path from the starting point is tangent to the cutting path.

[0015] Furthermore, in S2 and S4, the tool's tool drop path from the tool drop point into the cutting path is collinear with a section of the cutting path.

[0016] Furthermore, the intersection point of the knife drop path and the cutting path is the same as the intersection point of the knife start path and the cutting path.

[0017] Furthermore, the cutting board is smaller than the use area, and the cutting board is located within the use area.

[0018] In the present invention, the cutting plate is smaller than the use area to prevent cut glass fragments from entering the air pipe, causing air pipe blockage and easily causing stagnation of vacuum adsorption.

[0019] Furthermore, the cutting point and the cutting starting point are both within the waste area.

[0020] In the present invention, the knife landing point and the knife starting point are both in the waste area to avoid damage to the use area, thereby ensuring the good condition of the use area.

[0021] Furthermore, the bottom of the glass body is connected to a support plate on the outside, and the support plate is located within the waste area.

[0022] In the present invention, the support plate facilitates supporting the waste area to prevent the cut glass from falling and breaking.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The present invention fixes the glass body on the cutting plate through vacuum adsorption, then determines the cutting path of the glass body, determines the starting point and the ending point on both sides of the cutting path, then makes the tool enter from the starting point on one side, cuts the glass along the cutting path, then makes the tool move out from the starting point on the other side, adjusts the position of the tool, makes the tool move to the adjacent ending point, makes the tool enter from the ending point and cuts the glass body along the cutting path, then makes the tool move out from another ending point, thus completing the cutting. This method extends the cutting path to move the starting point and the ending point to the waste area, so that the special requirement of the starting point and the ending point coinciding can be completely avoided, thereby improving the occurrence of poor cutting, avoiding the corner chipping caused by the non-coincidence of the starting point and the ending point, and reducing the displacement distance of the tool through the starting point and the ending point on both sides.

Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention pertains. The terms used in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0033] For example, please refer to the attached Figure 1-3 A method for improving a cutting path for special-shaped cutting comprises the following steps:

[0034] S1, fixing the glass body 1 by a fixing device and determining a cutting path 2 of the glass body 1;

[0035] S2, determining the starting point 5 on both sides of the cutting path 2, and determining the falling point 4 on both sides of the cutting path 2, and making the falling point 4 close to the starting point 5;

[0036] S3, the tool enters from the starting point 5 on one side, cuts the glass along the cutting path 2, and moves out from the starting point 5 on the other side;

[0037] S4, moving the tool to an adjacent cutting point 4, allowing the tool to enter from the cutting point 4 and cut the glass body 1 along the cutting path 2, and then allowing the tool to move out from another cutting point 4;

[0038] S5, taking down the cut glass body 1, fixing the uncut glass body 1, and making the cutter start cutting from the adjacent starting point 5.

[0039] For example, please refer to the attached Figure 2 In S1, the fixing device is an adsorption device, including an air pump and a cutting plate connected to the air pump through an air pipe, and the top of the cutting plate is connected to the glass body 1.

[0040] It should be noted that, in the embodiment, the air pump is used to enable the cutting plate to vacuum-absorb the glass body 1 , so as to facilitate the cutting of the glass body 1 by the cutter.

[0041] For example, please refer to the attached Figure 2 The glass body 1 includes a waste area 3 and a use area 6, and the waste area 3 and the use area 6 are separated by a cutting path 2.

[0042] For example, please refer to the attached Figure 1-2 In S2 and S3 , the tool enters the starting path 7 of the cutting path 2 from the starting point 5 and is tangent to the cutting path 2 .

[0043] It should be noted that, in the embodiment, the tool starting path 7 is tangent to the cutting path 2 to facilitate the tool to cut along the cutting path 2 and to facilitate the tool to smoothly enter the cutting path 2.

[0044] For example, please refer to the attached Figure 1-2 In S2 and S4 , the tool's tool-falling path 8 from the tool-falling point 4 into the cutting path 2 is collinear with a section of the cutting path 2 .

[0045] It should be noted that, in the embodiment, the knife falling path 8 and a section of the cutting path 2 are collinear, which facilitates the tool to cut along the cutting path 2 and facilitates the tool to smoothly enter the cutting path 2.

[0046] For example, please refer to the attached Figure 2-3 The intersection point of the knife drop path 8 and the cutting path 2 and the intersection point of the knife start path 7 and the cutting path 2 are the same point.

[0047] It should be noted that, in the embodiment, the intersection points are the same point, which improves the cutting quality of the glass body 1 .

[0048] For example, please refer to the attached Figure 2-3 , the size of the cutting board is smaller than the use area 6, and the cutting board is located within the range of the use area 6.

[0049] It should be noted that, in the embodiment, the cutting plate is smaller than the use area 6 to prevent the cut glass fragments from entering the trachea through the air holes, causing the trachea to be blocked, which can easily cause the stagnation of vacuum adsorption, thereby easily causing the glass body 1 to move during the tool cutting process, resulting in cutting deviation.

[0050] For example, please refer to the attached Figure 2-3 The cutting point 4 and the cutting starting point 5 are both within the range of the waste area 3.

[0051] It should be noted that, in the embodiment, the knife drop point 4 and the knife starting point 5 are both in the waste area 3 to avoid damage to the use area 6, thereby ensuring the good condition of the use area 6, and can completely avoid the special requirement that the knife starting point 4 and the knife drop point 5 overlap, thereby improving the occurrence of poor cutting.

[0052] For example, please refer to the attached Figure 2 The bottom of the glass body 1 is connected to the outer side of the support plate, and the support plate is located within the waste area 3.

[0053] It should be noted that, in the embodiment, the support plate facilitates supporting the waste area 3 to prevent the cut glass from falling and breaking, so that the waste can be fully utilized.

[0054] The specific operation method of the present invention is as follows: the glass body 1 is fixed on the cutting board by vacuum adsorption, and then the cutting path 2 of the glass body 1 is determined, and the starting point 5 and the landing point 4 are determined on both sides of the cutting path 2, and then the tool enters from the starting point 5 on one side and cuts the glass along the cutting path 2, and then the tool moves out from the starting point 5 on the other side, adjusts the position of the tool, moves the tool to the adjacent landing point 4, and then enters from the landing point 4 and cuts the glass body 1 along the cutting path 2, and then moves the tool out from the other landing point 4 to complete the cutting.

[0055] The above description of the present invention is exemplified in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
