Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a wire cutting device. Background Art

[0002] In the display industry, it is often necessary to separate some defective display modules that have been formed by pasting in order to recover the display or touch components therein. Traditionally, there are two ways to separate such adhesive display modules: low-temperature separation and wire cutting separation. Both methods are physical separations. The former uses ultra-low temperature conditions to significantly weaken the molecular movement of adhesive polymer materials to achieve separation, while the latter uses ultra-fine or ultra-high strength metal wires to cut the adhesive material to achieve separation.

[0003] Some adhesive display modules are highly sensitive to temperature, and ultra-low temperature environments will permanently damage product performance, so low-temperature separation is not applicable. Wire cutting only uses metal wires to cut the adhesive material, which will not affect the adhesive display module product itself. For adhesive display modules that are not suitable for low-temperature separation, wire cutting can only be used for separation.

[0004] However, the existing wire cutting machines have some technical problems. First, the wire will encounter great resistance when cutting in the viscose material, and it is very easy to break after long-term use, which seriously affects the product yield and efficiency. Secondly, the existing wire cutting efficiency is low. After the wire cutting, the viscose material will partially stick back. At this time, multiple wire cuttings are required to achieve the final separation.

[0005] Therefore, how to improve the wire breakage problem and enhance the efficiency of wire cutting has become an issue that needs to be urgently addressed in the industry. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] In the description of the present invention, it is to be understood that a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] To illustrate the wire cutting device provided by the present application, the following is a detailed description in conjunction with the accompanying drawings and the textual description of the embodiments.

[0036] Reference below Figure 1-Figure 3 A wire cutting device 100 according to an embodiment of the first aspect of the present invention is described. Figure 1-Figure 3As shown, the wire cutting device 100 includes a base 110, a first cutting assembly 120 and a second cutting assembly 130. Specifically, the base 110 includes a frame 111 and a stage 112. The stage 112 is arranged on the frame 111. The stage 112 has a first surface 1121 and a second surface 1122. The first surface 1121 of the stage 112 is used to place the display product to be separated. Further, the first cutting assembly 120 includes a first driving member 121 and a first cutting line 122. The first driving member 121 is arranged on the frame 111, and the first cutting line 122 is located above the first surface 1121 of the stage 112. The first driving member 121 can drive the first cutting line 122 to reciprocate, thereby realizing the first cutting. The cutting line 122 contacts the display product to be separated and realizes cutting. Furthermore, the second cutting component 130 includes a winding post and a second cutting line 133. The winding post is arranged on the frame 111, and the winding post contacts the second cutting line 133 and realizes limiting, and the second cutting line 133 is located above the first surface 1121 of the stage 112, so that the first cutting line 122 contacts the display product to be separated and realizes cutting. It can be seen that this scheme can better realize cutting and separation through multiple cutting by setting the first cutting component 120 and the second cutting component 130, thereby increasing the effect of completing separation in one cutting to avoid multiple cutting, and the use of multiple cutting can effectively reduce the overall cutting resistance and reduce the phenomenon of wire breakage.

[0037] It should be noted that the second cutting line 133 can be stationary or rotating during cutting, that is, the second cutting line 133 can be set to be not connected to a driving member, or the second cutting line 133 can be set to be connected to a driving member, that is, the second cutting line 133 can be rotated under the drive of the driving member. It can be understood that as long as the second cutting line 133 remains in a tensioned state during cutting, the second cutting line 133 can be set to be stationary or rotating according to the usage scenario.

[0038] It should be noted that the first cutting line 122 and the second cutting line 133 need to be parallel to the first surface 1121 of the stage 112, so as to ensure that the first cutting line 122 and the second cutting line 133 are in parallel contact with the adhesive layer of the display product to be separated, and avoid cutting damage caused by the first cutting line 122 and the second cutting line 133 contacting the non-adhesive layer of the display product to be separated during cutting.

[0039] It should be noted that, in addition to the first cutting line 122 and the second cutting line 133, a plurality of additional cutting lines may be provided. For example, a third cutting line may be provided. The third cutting line may be provided after the first cutting line 122 and the second cutting line 133 and in contact with the display product to be separated. In this case, the cutting and separation effect may be further enhanced. It is understandable that, depending on different usage scenarios, a plurality of additional cutting lines may be provided, and no specific limitation is made here.

[0040] According to one embodiment of the present invention, Figure 3 As shown, the first cutting line 122 and the second cutting line 133 are at the same distance from the first surface 1121. It can be understood that by setting the first cutting line 122 and the second cutting line 133 to be at the same distance from the first surface 1121, the first cutting line 122 and the second cutting line 133 are in contact with the display product to be separated at the same position, which further increases the cutting and separation effect. At the same time, it avoids the difference in height between the two, which causes the first cutting line 122 or the second cutting line 133 to contact the non-adhesive layer of the display product to be separated and cause cutting damage.

[0041] According to one embodiment of the present invention, Figure 2 As shown, the winding rod includes a first winding rod 131 and a second winding rod 132, and the first winding rod 131 and the second winding rod 132 are respectively arranged on both sides of the stage 112. It can be understood that by arranging the first winding rod 131 and the second winding rod 132 on both sides of the stage 112, it can be ensured that the tensioned state is maintained during cutting, thereby achieving contact with the display product to be separated.

[0042] According to one embodiment of the present invention, Figure 2 As shown, the second cutting line 133 is a line connected end to end, and the first winding post 131 and the second winding post 132 are arranged in a figure formed by the second cutting line 133 connected end to end. It can be understood that by setting the second cutting line 133 as a cutting line connected end to end, during the cutting process, the second cutting line 133 actually cuts the display product to be separated twice, thereby further enhancing the cutting effect.

[0043] According to one embodiment of the present invention, Figure 2 As shown, the second cutting assembly 130 also includes a second driving member 134, and the first winding post 131 and / or the second winding post 132 are connected to the second driving member 134. It can be understood that by providing a second driving member 134 connected to the first winding post 131 and / or the second winding post 132, the first winding post 131 and / or the second winding post 132 can be driven to rotate by the second driving member 134, thereby driving the second cutting line 133 to achieve reciprocating motion, thereby further enhancing the cutting effect.

[0044] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown, the first cutting assembly 120 also includes at least two guide wheels 123, which are in contact with the first cutting line 122. By setting the guide wheels 123 in contact with the first cutting line 122, the first cutting line 122 can always be kept in a tensioned state during the cutting process, further enhancing the cutting effect.

[0045] According to one embodiment of the present invention, Figure 1-Figure 3 As shown, the first cutting line 122 and the second cutting line 133 are metal wires. Specifically, the first cutting line 122 and the second cutting line 133 can be one of copper wires, aluminum wires or molybdenum wires. It can be understood that by setting the first cutting line 122 and the second cutting line 133 as metal wires, the cutting effect can be enhanced and the risk of wire breakage can be reduced.

[0046] According to one embodiment of the present invention, an adjusting device (not shown in the figure) is also included, which can drive the first driving member 121 and the winding column to move up and down. It can be understood that due to the different heights of the display products to be separated, the adjusting device can be set to adjust the height of the first cutting line 122 and the second cutting line 133 according to the heights of different display products to be separated, thereby meeting the actual usage scenario.

[0047] According to one embodiment of the present invention, Figure 3 As shown, the cross-sectional figure of the first cutting line 122 and the second cutting line 133 is circular, and the diameter of the cross-sectional figure is 0.15-2mm, for example, the diameter of the first cutting line 122 and the second cutting line 133 is 0.15mm, or the diameter of the first cutting line 122 and the second cutting line 133 is 0.18mm, or the diameter of the first cutting line 122 and the second cutting line 133 is 0.2mm, or the diameter of the first cutting line 122 and the second cutting line 133 is 0.3mm, or the diameter of the first cutting line 122 and the second cutting line 1 The diameter of the first cutting line 122 and the second cutting line 133 is 0.5mm, or the diameter of the first cutting line 122 and the second cutting line 133 is 0.8mm, or the diameter of the first cutting line 122 and the second cutting line 133 is 1mm, or the diameter of the first cutting line 122 and the second cutting line 133 is 1.5mm, or the diameter of the first cutting line 122 and the second cutting line 133 is 2mm. It can be understood that different sizes of first cutting lines 122 and second cutting lines 133 can be used according to different display products to be separated to meet different usage scenarios.

[0048] According to one embodiment of the present invention, Figure 3As shown, the diameter of the first cutting line 122 is greater than the diameter of the second cutting line 133. It can be understood that since the first cutting line 122 first contacts the display product to be separated, the resistance encountered by the first cutting line 122 during the cutting process is greater than the resistance encountered by the second cutting line 133, so the diameter of the first cutting line 122 needs to be set to be greater than the diameter of the second cutting line 133. For example, the diameter of the first cutting line 122 is 0.2 mm, and the diameter of the second cutting line 133 is 0.18 mm, or the diameter of the first cutting line 122 is 0.5 mm, and the diameter of the second cutting line 133 is 0.2 mm, or the diameter of the first cutting line 122 is 1 mm, and the diameter of the second cutting line 133 is 0.8 mm. It can be understood that, depending on the different display products to be separated, first cutting lines 122 and second cutting lines 133 of different sizes can be used to meet different usage scenarios.
