Description

Technical Field

[0001] The utility model relates to the technical field of a chip splitting process, in particular to a chip splitting device that can be used for streamlined production. Background Art

[0002] With the development of science and technology, life is becoming more and more advanced. With the advent of the digital age, the high-tech industry has been vigorously developed. The scale of the industry and the fierce competition among international manufacturers in the field of liquid crystal display (LCD) are expanding day by day. LCD devices have many advantages such as high image quality, small size, light weight, low driving voltage and low power consumption. Therefore, they are widely used in consumer communication or electronic products such as personal digital assistants (PDAs), mobile phones, camcorders, notebook calculators, desktop monitors, car monitors and projection TVs, and have become the mainstream of displays.

[0003] The liquid crystal display panel is a flat ultra-thin display device. The main body of a general liquid crystal display panel is mainly composed of a thin film transistor, a liquid crystal unit and a color filter. The liquid crystal unit is arranged between the thin film transistor and the color filter. The above structure is encapsulated between two transparent substrates. The liquid crystal display uses the signal and voltage of the thin film transistor to change and control the rotation direction of the liquid crystal molecules in the liquid crystal unit, thereby controlling the polarized light of each pixel point and achieving the display purpose.

[0004] In the processing of liquid crystal display panels, a large panel is usually processed and then the large panel is cut into the required small-sized panels. In this process, there are two main steps: cutting and splitting. The cutting step mainly uses a knife wheel with a certain hardness to apply a certain pressure to pass between the effective panel of the liquid crystal display panel and the discarded scraps to be cut, thereby leaving a cutting line on the surface of the liquid crystal display panel; and the splitting step uses the splitting principle to deepen the crack depth of the cutting line until the crack of the cutting line can completely separate the effective panel of the liquid crystal display panel from the discarded scraps.

[0005] In the prior art, the technology related to the splitting step can be divided into four methods: clamping method, knocking method, breaking and slicing method and high-flow hot gas method. The clamping method mainly fixes and clamps the portion of the liquid crystal display panel to be removed outside the cutting line through the upper and lower clamps to eliminate the residual material; the knocking method mainly applies a moderate external force to knock on the portion of the liquid crystal display panel to be removed outside the cutting line to eliminate the residual material. The breaking and slicing method mainly applies an external force to the panels on both sides of the cutting line through the device, so as to deepen the crack of the cutting line and separate the effective panel from the residual material; the high-flow hot gas method mainly uses high-speed hot gas to impact the cutting line, so as to deepen the crack of the cutting line and separate the effective panel from the residual material. Regarding the above methods, although all of them can achieve the splitting effect, most of the current splitting methods require the liquid crystal display surface to be processed in a static state, and it is impossible to process multiple cutting lines of the liquid crystal display panel at the same time, resulting in low efficiency of the processing splitting process.

[0006] In view of the foregoing, the inventor of the present invention has considered and designed a wafer splitting device in order to improve the deficiencies of the prior art, thereby providing an effective and rapid wafer splitting process to enhance industrial implementation and utilization.

DETAILED DESCRIPTION

[0044] The advantages, features and technical methods achieved by the present invention will be described in more detail with reference to exemplary embodiments and drawings so as to be easier to understand, and the present invention can be implemented in different forms, so it should not be understood as being limited to the embodiments described herein. On the contrary, for technicians in the technical field to which the present invention belongs, the provided embodiments will make the disclosure more thorough and comprehensive and fully convey the scope of the present invention, and the present invention will only be defined by the attached claims.

These terms are only used to distinguish one component, part, region, section, layer and / or part from another component, part, region, section, layer and / or part.

[0047] There are many ways to crack liquid crystal display panels, such as clamping, knocking, breaking and high-flow hot gas. However, the equipment for cracking processes using the above methods cannot achieve streamlined production. Usually, the equipment for cracking processes requires a short residence time for cracking. Therefore, it is difficult to meet the current manufacturing needs of a large number of liquid crystal display panels. Therefore, the existing technology is improved to provide a cracking device.

[0048] See also Figure 1, which is a schematic diagram of the slicing device of the present invention. As shown in the figure, the slicing device 1 of the present invention comprises a conveying device 11 and at least one slicing roller set 12. The at least one slicing roller set 12 is fixedly arranged on one side of the conveying device 11 parallel to the conveying direction; in the attached figure, two groups of slicing roller sets 12 are used as a demonstration, and the two groups of slicing roller sets 12 are respectively fixedly arranged on both sides of the conveying device 11 perpendicular to the conveying direction. The present invention mainly realizes a streamlined slicing process of the material 2 through the combination of the conveying device 11 and at least one slicing roller set 12, thereby improving the efficiency of the slicing process. The material 2 is a liquid crystal display panel, which includes a two-layer structure, a first layer is a color filter and a second layer is a thin film transistor. The color filter of the first layer has a body 20 and at least one residual material 22. The at least one residual material 22 is located on at least one side of the material 2 parallel to the conveying direction, and at least one cutting line 21 is provided on the outer side of the color filter of the first layer. At least one cutting line 21 is used to distinguish the body 20 from the at least one residual material 22. The material 2 has a side with the at least one residual material 22 facing away from or facing the conveying device 11.

[0049] In the present invention, the conveying device 11 is used to carry and transport the material 2 (such as a liquid crystal display panel) along the conveying direction. The conveying device 11 can be a conveyor belt, roller, ball, drum or chain, etc. The present invention does not limit the conveying method of the conveying device 11, and the conveying device 11 of the present invention is described by taking a conveyor belt as an example. At least one split roller group 12 is fixed on the conveying path of the conveying device 11; at least one split roller group 12 can be one split roller group 12 or two split roller groups 12, and the two split roller groups 12 are symmetrically arranged on the left and right sides of the conveying device 11. Therefore, the present invention is mainly described below with respect to the relevant changes of one of the split roller groups 12.

[0050] See also Figure 2 , which is a schematic diagram of the first embodiment of the splitting device of the utility model. As shown in the figure, the splitting roller group 12 includes at least one upper roller 121 and at least one lower roller 122. Here, the at least one lower roller 122 is not limited to a single lower roller 122 or multiple lower rollers 122, and the at least one upper roller 121 is not limited to a single upper roller 121 or multiple upper rollers 121. In this embodiment, the at least one upper roller 121 and the at least one lower roller 122 are both described as a single roller as an exemplary state.

[0051] The lower roller 122 is located on one side of the cutting line 21 in the area covered by the body 20, and one side of the lower roller 122 is flush with the cutting line 21. It is worth mentioning that the lower roller 122 has a predetermined angle with the material 2, preferably, the predetermined angle can be ±60 degrees (when the wafer flow direction is 0 degrees); if the predetermined angle is too large, it will cause the problem of abnormal roller rotation, and if the predetermined angle is too small, it may cause the problem of poor chip yield. In addition, the upper roller 121 is located on the other side of the cutting line. Optionally, the side of the body 20 is located between the two sides of the upper roller 121, or as shown in the figure, the upper roller 121 and the lower roller 122 are located on the same imaginary vertical line.

[0052] Among them, the residual material 22 on at least one side of the material 2 is on one side of the conveying device 11, and the conveying device 11 conveys the material 2 through the splitting roller group 12 for the splitting process. When the material 2 continues to move, it is pressed from the bottom and top by the lower roller 122 and the upper roller 121 at the same time, and then the material 2 is split by the cutting line 21 in the moving state to peel off the residual material 22 from the material 2.

[0053] It is worth mentioning that the vertical distance from the lower roller 122 to the upper roller 121 is a spacing H, the material 2 has a thickness T, and the spacing H is smaller than the thickness T. This part of the technology is mainly an important means for the material 2 to pass through the splitting roller group 12, and the splitting roller group 12 generates a force to press the material 2, thereby performing the splitting process.

[0054] In addition, before the splitting process is performed, the thickness of the material 2, the toughness of the material, or the size of the residual material 22 and other related conditions should be evaluated first, and according to the above-mentioned related conditions, the spacing H between the lower roller 122 and the upper roller 121 is adjusted by a moving or driving mechanism, and the present embodiment does not limit the adjustment method of the moving or driving mechanism to manual adjustment or automatic adjustment. Among them, if the spacing H between the lower roller 122 and the roller 121 is smaller than the thickness T of the material 2, the resistance of the material 2 to be introduced into the lower roller 122 and the upper roller 121 is too large, and the material 2 cannot be smoothly introduced into the splitting roller assembly 12; or, the material 2 is damaged due to the large resistance of the pressing. If the distance H between the lower roller 122 and the upper roller 121 is too large compared to the thickness T of the material 2, the lower roller 122 and the upper roller 121 cannot exert a pressing force on the material 2, that is, no force is exerted on the cutting line 21 of the material 2, and the splitting process cannot be performed. This embodiment can adjust the lower roller 122 and the upper roller 121 to the most appropriate position according to the relevant conditions of the material 2 by using a moving or driving mechanism.

[0055] See also Figure 3 , which is a schematic diagram of a second embodiment of the splitting device of the present utility model.

[0056] As shown in the figure, the split roller assembly 12 includes at least one upper roller 121 and at least one lower roller 122. In this embodiment, the number of the at least one lower roller 122 is one and the number of the at least one upper roller 121 is two as an exemplary embodiment.

[0057] The two upper rollers 121 are respectively a first upper roller 121A and a second upper roller 121B. The lower roller 122 and the second upper roller 121B are located on one side of the cutting line 22 of the area covered by the body 20, and the first upper roller 121A is located on the other side of the cutting line 22. Preferably, one side of the lower roller 122 is flush with the cutting line 22, the side of the body 20 is located between the two sides of the first upper roller 121A, and the second upper roller 121B and the lower roller 122 are located on the same imaginary vertical line.

[0058] It is worth mentioning that the first upper roller 121A and the second upper roller 121B are arranged at intervals along the directions of both sides of the material 2 , and the distance between the first upper roller 121A and the lower roller 122 is smaller than the distance between the second upper roller 121B and the lower roller 122 .

[0059] As mentioned above, when the material 2 is undergoing the splitting process, the first upper roller 121A can achieve a similar effect of breaking the material 2 (through the cutting line 22), and then the material 2 is pressed from the bottom and top by the lower roller 122 and the upper roller 121 at the same time, so that the material 2 is split along the cutting line 21 in a moving state to peel off the residual material 22 from the material 2; thereby, a stronger splitting force and a stable splitting effect can be achieved.

[0060] See also Figure 4 , which is a schematic diagram of a third embodiment of the splitting device of the present utility model.

[0061] As shown in the figure, in this embodiment, at least one lower roller 122 and at least one upper roller 121 are described as a single roller. The upper roller 121 and the lower roller 122 are located on the same imaginary vertical line, and the upper roller 121 is located above the lower roller 122. The top edge of the lower roller 122 is parallel to the bearing surface of the conveying device 11 that carries the material 2. Further, a moving or driving mechanism, such as a moving mechanism 120, is respectively disposed on the lower roller 122 and the upper roller 121; the moving mechanism 120 can respectively adjust the positions of the lower roller 122 and the upper roller 121 in the up-down direction or the left-right direction.

[0062] Please also read Figure 5 , which is Figure 4 As shown in the figure, in this embodiment, the distance H between the lower roller 122 and the upper roller 121 is the thickness T of the material 2, and the distance H is smaller than the thickness T. This part of the technology is mainly an important means for the material 2 to pass through at least one splitting roller assembly 12, and the splitting roller assembly 12 generates a force to press the material 2, thereby performing the splitting process.

[0063] In this embodiment, at least one upper roller 121 is located directly above at least one lower roller 122 , the material 2 is introduced between the at least one lower roller 122 and the at least one upper roller 121 , and the at least one lower roller 122 and the at least one upper roller 121 are located on one side of at least one cutting line 21 of the material 2 .

[0064] In this embodiment, the material 2 is pushed between the lower roller 122 and the upper roller 121 by the conveying device 11. At the same time, when the material 2 passes between the lower roller 122 and the upper roller 121, the lower roller 122 and the upper roller 121 are driven by the material 2 to roll in the conveying direction of the material 2; that is, the lower roller 122 rotates clockwise, and the upper roller 121 rotates counterclockwise. Moreover, the interval H between the lower roller 122 and the upper roller 121 is smaller than the thickness T of the material 2; therefore, when the material 2 moves through the splitting roller assembly 12, the material 2 will be in a state of continuous movement, and will be pressed upward by the lower roller 122 and pressed downward by the upper roller 121, so that the material 2 is pressed by the upper and lower forces at the same time, and under this pressing condition, the material 2 is continuously introduced and pushed by the conveying device 11, and this force acts on the cutting line 21 of the material 2, which will make the gap of the cutting line 21 larger and larger, until the gap of the cutting line 21 completely splits through a color filter of the first layer of the material 2, and the residual material 22 is peeled off from the color filter layer of the material 2, and the material 2 also passes through the splitting roller assembly 12 in a state of continuous movement.

[0065] This embodiment improves the technology of the existing equipment for the splitting process. The existing methods for the splitting process include clamping, knocking, breaking and high-speed hot gas. However, in the process of splitting, the material needs to be split in a static state, and it is impossible to split the cutting lines on both sides of the material at the same time, resulting in low efficiency of the splitting process. Therefore, the splitting equipment of the utility model, through the above configuration, the material 2 is kept in a moving state for splitting, and the streamlined splitting process method can improve the splitting efficiency, which is also conducive to the splitting process of the double-layer structure.

[0066] Please also read Figure 6 and Figure 7 , which is a schematic diagram of a roller and another schematic diagram of a splitting device of the fourth embodiment of the utility model. As shown in the figure, the difference between this embodiment and the previous embodiment is that at least one lower roller 122 and at least one upper roller 121 are set for an asymmetric material 2. Figure 6 The lower roller 122 is located on one side of the cutting line 21 of the material 2, and the upper roller 121 is located on the other side of the cutting line 21 of the material 2, or the lower roller 122 and the upper roller 121 are located on the same side of the cutting line 21 (not shown), and Figure 7 The implementation method of is set in the opposite manner to the implementation method of Figure 7, so it will not be repeated here.

[0067] The lower roller 122 and the upper roller 121 of this embodiment are set asymmetrically, and the force that can be generated varies greatly. The direction of the force on the material 2 is also different. The implementation method of this embodiment can select a suitable roller setting position based on relevant conditions such as the thickness of the material 2, the material toughness or the size of the residual material 22.

[0068] Please also read Figure 8 and Fig. 9 , which is a schematic diagram of a roller and another schematic diagram of a slicing device of the fifth embodiment of the utility model. As shown in the figure, the difference between this embodiment and the previous embodiment is that when there are two upper rollers 121 and one lower roller 121, the two upper rollers 121 are parallel and arranged at the same height (along the two sides of the material 2), and the lower roller 122 corresponds to one of the two upper rollers 121, and the two upper rollers 121 can be respectively arranged on both sides of the cutting line 21, or on the same side of the cutting line 21 (not shown). Figure 8 The lower roller 122 corresponds to the outer roller of the two upper rollers 121. Fig. 9 The lower roller 122 corresponds to the inner roller of the two upper rollers 121 .

[0069] The arrangement of the lower roller 122 and the upper roller 121 of this embodiment is suitable for the material 2 with high toughness. If the material 2 with high material toughness is subjected to the splitting process in the roller arrangement manner of the fourth embodiment, one side of the material 2 will be warped, making it difficult to perform the splitting process. Therefore, one of the two upper rollers 121 is arranged above the lower roller 122 to clamp and fix the material 2 to prevent the material 2 from warping, so as to facilitate the splitting process.

[0070] Please also read Fig.10 and Fig.11 , which is a schematic diagram of a roller and another schematic diagram of a slicing device of the sixth embodiment of the utility model. As shown in the figure, the difference between this embodiment and the previous embodiment is that when there is at least one upper roller 121 and at least two lower rollers 122, the two lower rollers 122 are parallel to each other and arranged at the same height (along the two sides of the material 2), the upper roller 121 corresponds to one of the two lower rollers 122, and the two lower rollers 122 can be respectively arranged on both sides of the cutting line 21, or on the same side of the cutting line 21 (not shown). Fig.10 The upper roller 121 corresponds to the outer roller of the two lower rollers 122. Fig.11 The upper roller 121 corresponds to the inner roller of the two lower rollers 122. The effect and purpose of this embodiment are the same as those of the fifth embodiment, so they will not be described again.

[0071] See also Fig.12, which is a roller schematic diagram of the slicing device of the seventh embodiment of the utility model and another roller schematic diagram. As shown in the figure, the difference between this embodiment and the previous embodiment is that when at least one upper roller 121 is two upper rollers 121 and at least one lower roller 122 is a lower roller, the two upper rollers 121 are arranged front and back (along the conveying direction) and arranged with the front higher and the back lower, that is, the vertical distance from the lower roller 122 to the front roller of the two upper rollers 121 is the spacing h1, and the vertical distance from the lower roller 122 to the rear roller of the two upper rollers 121 is the spacing h2, and the spacing h1 is greater than the spacing h2; and the thickness T of the material 2 is greater than or equal to the spacing h1.

[0072] As described above, when the material 2 is subjected to the splitting process, because the thickness T of the material 2 is greater than or equal to the distance h1 between the lower roller 122 and the front rollers of the second upper rollers 121, the material 2 is transported by the conveying device 11 and introduced between the lower roller 122 and the front rollers of the second upper rollers 121, and the resistance generated is small. The material 2 can be introduced between the lower roller 122 and the front rollers of the second upper rollers 121 through the pushing of the conveying device 11. Then, the material 2 is further introduced between the lower roller 122 and the rear rollers of the second upper rollers 121. Since the spacing h2 is smaller than the spacing h1, the material 2 encounters greater resistance when being introduced between the lower roller 122 and the rear roller of the second upper roller 121; however, the material 2 is continuously pushed by the external force of the conveying device 11, and at the same time, the lower roller 122 and the front rollers of the second upper rollers 121 fix the moving direction and position of the material 2, and continue to introduce the material 2 between the lower roller 122 and the rear roller of the second upper roller 121, and the material 2 is subjected to a stronger force between the lower roller 122 and the rear rollers of the second upper rollers 121, resulting in a splitting effect.

[0073] In the present embodiment, due to the thickness of the material 2, the toughness of the material or the size of the residual material 22 and other related conditions, a greater force needs to be applied to the material 2 for the splitting process. However, if the lower roller 122 and the upper roller 121 are to be able to apply sufficient force to the material 2 for the splitting process, the smaller the vertical distance from the lower roller 122 to the horizontal height of the upper roller 121, the greater the force applied to the material 2 after being introduced into the splitting roller group, which will also cause the material 2 to need to be introduced into the splitting roller group 12 with a greater external force; in this case, the present embodiment introduces the material 2 into the splitting roller group 12 through a progressive method, and gradually increases the pressure generated between the lower roller 122 and the two upper rollers 121, so that the material 2 can be subjected to a force sufficient for the splitting process.

[0074] Please also read Fig.13, which is a roller schematic diagram of the splitting device of the eighth embodiment of the utility model and another roller schematic diagram. As shown in the figure, the difference between this embodiment and the previous embodiment is that the arrangement of the lower roller 122 and the upper roller 121 is reversed. When at least one lower roller 122 is two lower rollers 122 and at least one upper roller 121 is one upper roller 121, the two lower rollers 122 are arranged front to back, and arranged with the front lower and the rear higher (along the conveying direction), that is, the vertical distance from the upper roller 121 to the front roller of the two lower rollers 122 is the spacing h3, and the vertical distance from the upper roller 121 to the rear roller of the two lower rollers 122 is the spacing h4, and the spacing h3 is greater than the spacing h4; and the thickness T of the material 2 is greater than or equal to the spacing h3. The effect and purpose of this embodiment are the same as those described in the fifth embodiment, so they are not repeated.

[0075] Please also read Fig.14 and Fig.15 , which is a schematic diagram of the material of the ninth embodiment of the present utility model. As shown in the figure, in this embodiment, it is used to illustrate that the material 2 is a double-layer structure, such as a combination of a color filter and a thin film transistor in a liquid crystal display panel. In addition to being applicable to the most basic single-layer structure, this embodiment can also achieve the same splitting effect for a double-layer structure. The thickness of the material 2, the material toughness, or the size of the residual material 22 and other related conditions are evaluated, and the appropriate roller setting position (such as the first to sixth embodiments) is selected. In this embodiment, the double-layer structure of the material 2 is illustrated, and the distribution mode of at least one residual material 22 in both layers can all be used to perform the splitting process using the splitting device 1. This embodiment is not limited to the splitting process of a single-layer or double-layer structure, nor is it limited to the distribution mode of at least one residual material 22. The splitting roller group 12 can be adjusted according to the material 2.

[0076] Please also read Fig.16 and Fig.17 , which are the front view and side view of the roller of the splitting device of the tenth embodiment of the utility model. As shown in the figure, the difference between this embodiment and the previous embodiment is that the wheel body style of at least one lower roller 122 or at least one upper roller 121 is further changed. Taking the front view of this embodiment as an example, there is a protrusion 123 in the middle of the roller. The protrusion 123 is conducive to the pressure of at least one lower roller 122 or at least one upper roller 121 to be concentrated on a force line, and the pressure force is more concentrated. The roller style of this embodiment is applicable to the previous embodiments.

[0077] Please also read Fig.18 and Fig.19, which are the front view and side view of the roller of the slicing device of the eleventh embodiment of the utility model. As shown in the figure, the difference between this embodiment and the previous embodiment is that the wheel body style of at least one lower roller 122 or at least one upper roller 121 is further changed. Taking the side view of this embodiment as an example, the roller is designed as a serrated portion 124. This embodiment is also applicable to the previous embodiments. In addition, the utility model does not limit the roller style. Regardless of the roller style of the ninth embodiment or the roller style of the tenth embodiment, they are all adjusted according to the relevant conditions such as the thickness of the material 2, the material toughness or the size of the residual material 22.

[0078] See also Fig. 20 and Fig.21 , which is a side view and a top view of the front and rear sensors of the twelfth embodiment of the splitting device of the utility model. As shown in the figure, the difference between this embodiment and the previous embodiment is that this embodiment further provides at least one front sensor 31, which is located in front of at least one splitting roller group 12, and is used to detect the position, width or thickness of the material 2.

[0079] In this embodiment, before the material 2 is subjected to the splitting process, the moving mechanism 120 is used to adjust the lower roller 122 and the upper roller 121 to the most appropriate position, and the material 2 is continuously moved from the conveying device 11 to the splitting roller group 12; however, not every position of the material 2 placed on the conveying device 11 can be accurately aligned with the splitting roller group 12. Therefore, at least one front sensor 31 is used to detect the position of the material 2 on the conveying device 11, that is, the sensor is used to detect the two sides of the material 2 for positioning, and then at least one roller group 12 is moved as a whole according to the position of the material 2 after positioning; that is, the relative position of the lower roller 122 and the upper roller 121 remains unchanged, and the splitting roller group 12 is aligned with the cutting line 21 of the material 2, so that the splitting process can be effectively performed. In addition, the front sensor 31 can also be used to detect the thickness and width of the material 2 as relevant data that can be used in subsequent processes.

[0080] Furthermore, at least one rear sensor 32 is further provided, and the at least one rear sensor 32 is located behind the splitting roller assembly 12, and the at least one rear sensor 32 is used to detect the width or thickness of the material 2. In this embodiment, the at least one rear sensor 32 is used in conjunction with the front sensor 31, and the width or thickness of the material 2 detected by the rear sensor 32 is compared with the width or thickness of the material 2 detected by the front sensor 31, so as to obtain the difference between the completed data of the material 2 after the splitting process and the original data of the material 2 before the splitting process, so as to detect whether the material 2 has completed the steps of the splitting process, whether at least one residual material 22 of the material 2 has fallen off, and so on.

[0081] In summary, the splitting device of the utility model includes a conveying device and a splitting roller group. A material (such as a liquid crystal display panel) is taken. A cutting line is provided on the outside of the material. The cutting line is used to separate the residual material of the material. The material is transported by the conveying device for the splitting process. The splitting roller group is arranged on one side of the conveying device. The splitting roller group includes at least one lower roller and at least one upper roller located above the at least one lower roller. The thickness of the material is greater than the vertical distance from the lower roller to the upper roller. When the material moves through the splitting roller group, the material is pressed from the upper and lower directions by the upper roller and the lower roller during the continuous movement, and then the residual material of the material is split by the cutting line. The splitting device of the utility model can use a streamlined splitting process to improve the splitting efficiency. In addition, at least one front sensor and at least one rear sensor are further provided. The material position is detected for positioning, and the thickness and width of the material are detected to detect whether the material has completed the splitting process.
