Description

Technical Field

[0001] The present application relates to the technical field of liquid crystal manufacturing, and in particular to a cutting device for producing LCD liquid crystal screen modules. Background Art

[0002] LCD screen is a display technology that uses liquid crystal as an optical switch. It is widely used in various devices, such as computer monitors, TVs, smart phones and other portable electronic devices. In the production process of the liquid crystal box of the liquid crystal panel, the large piece of liquid crystal screen glass behind the box needs to be separated into individual liquid crystal boxes by cutting and splitting, and then the liquid crystal is added, flattened and sealed to complete the preparation of the liquid crystal box.

[0003] In the LCD glass cutting process, the cutter wheel needs to perform X-direction and Y-direction cutting on the same side of the LCD glass. For example, the X-direction cutting is performed first to form the X-direction cutting marks, and then the Y-direction cutting is performed perpendicular to it. The LCD glass has been cut in the X-direction to form cutting marks. When the cutter wheel cuts the LCD glass in the Y-direction, it will intersect with the X-direction cutting marks formed in advance to form an intersection. The cutter wheel will collide with the intersection of the LCD glass. Since the internal stress of the LCD glass is difficult to dissipate quickly during the cutting process, the LCD glass is prone to edge collapse, breakage or sawtooth defects at the intersection, reducing the product yield. Summary of the invention

[0004] In order to improve the problem that edge chipping, breakage or jaggedness may occur at the intersection of the cutting seams of the LCD screen glass when the LCD screen glass is cut alternately vertically and horizontally, the present application provides a cutting device for LCD screen module production.

[0011] The machine platform is provided with a distance control component for adjusting the longitudinal position of the distance control rod.

[0012] Furthermore, the distance control assembly includes slide seats arranged at both ends of the distance control rod, and two first slide rails perpendicular to the distance control rod are arranged on the machine platform. The slide seats are slidably arranged on the first slide rails, and one end of the distance control rod slides through one of the slide seats, and the other end is threaded through the other slide seat.

[0013] Furthermore, a hand wheel or a driving motor is arranged at one end of the distance control rod threadedly passing through the slide seat.

[0014] Furthermore, one of the two adjacent sides of the limiting joint and the adjacent sliding sleeve is provided with a cone top, and the other is provided with a cone groove adapted thereto.

[0015] Furthermore, the separation mechanism includes a first magnetic body and a second magnetic body respectively arranged on adjacent ends of two laterally adjacent support platforms, and the first magnetic body and the second magnetic body magnetically repel each other.

[0016] Furthermore, at least one of the first magnetic body and the second magnetic body is an electromagnet, and the longitudinal cutter wheel is connected to a first controller, and the electromagnet is control-connected to the first controller;

[0017] When the longitudinal cutter wheel completes the longitudinal cutting of the liquid crystal screen, the first controller controls the electromagnet to be energized and magnetized.

[0018] Furthermore, one of the plurality of supporting groups is fixed on the machine platform.

[0023] 2. After the longitudinal cutting, gaps are formed between the multiple longitudinal strips of LCD screens, so that when the transverse cutter wheel performs transverse cutting, only a "T"-shaped intersection cut is formed on the long side of the longitudinal strip of LCD screens. Compared with the "cross"-shaped intersection cut produced by the transverse cutting directly after the longitudinal cutting in the current cutting process, the stress in the LCD screen can be released to a certain extent, making the probability of edge collapse of the LCD screen at the intersection lower, and thus the yield rate of the display screen cutting products can be improved to a certain extent;

[0024] 3. When the horizontal blade wheel is cutting the horizontal cutting seam, the vertical long LCD screen can be swayed along the horizontal cutting seam during the horizontal cutting process, which can reduce the irregular edges and cracks of the LCD screen after cutting and improve the cutting accuracy; and can disperse the internal stress of the LCD screen and reduce cracks not on the cutting line caused by stress concentration; and the slight shaking of the LCD screen itself can make the fracture of the LCD screen smoother and reduce the edge collapse phenomenon, thereby greatly reducing the edge collapse, breakage or sawtooth defects of the LCD screen when it is completely cut, and improving the product yield.

[0038] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0039] The present application embodiment discloses a cutting device for producing LCD liquid crystal screen modules. Figure 1 and Figure 2, which includes a machine 1, a longitudinal cutter wheel 21 and a transverse cutter wheel 22 arranged on the machine 1, and a mechanical arm 23 for driving the longitudinal cutter wheel 21 and the transverse cutter wheel 22 to move on the machine 1, and one or more longitudinal cutter wheels 21 and transverse cutter wheels 22 can be set, and the mechanical arm 23 only needs to make multiple or one round trip to complete the cutting of a large LCD screen; and the longitudinal cutter wheel 21 and the transverse cutter wheel 22 are driven by a motor to rotate at a high speed to cut the LCD screen, and the longitudinal cutter wheel 21 cuts a longitudinal cutting seam on the LCD screen, and the transverse cutter wheel 22 cuts a transverse cutting seam on the LCD screen. The mechanical arm 23 can be a two-axis mechanical arm 23 or a three-axis mechanical arm 23, and the longitudinal cutter wheel 21 and the transverse cutter wheel 22 correspond to one mechanical arm 23 respectively, or the two share one mechanical arm 23, and its specific configuration can be simply set according to actual production needs, which will not be repeated here.

[0040] A plurality of movable grooves 11 are provided on the table surface of the machine 1, and a supporting platform 31 is slidably arranged in the movable groove 11. The dimension of the movable groove 11 along the length direction of the transverse cutting seam is greater than the dimension of the supporting platform 31 in this direction, that is, the supporting platform 31 can slide in the sliding groove along the direction of the transverse cutting seam. The supporting platform 31 has an adsorption hole 311 for negative pressure adsorption of the liquid crystal screen, and the adsorption hole 311 is connected to an external negative pressure vacuum device. In order to ensure the fixed adsorption effect of the supporting platform 31 on the cut liquid crystal screen, a rubber layer is attached to the supporting platform 31, and the adsorption hole 311 is arranged through the rubber layer.

[0041] Reference Figure 1 and Figure 2 , multiple supporting platforms 31 are arranged in a matrix on the machine 1, and multiple supporting platforms 31 arranged vertically are set as a supporting group 3, and multiple supporting platforms 31 in a supporting group 3 are commonly connected to a longitudinally arranged guide rod 41, and a guiding structure for guiding the two ends of the guide rod 41 to move only in a direction perpendicular to the length direction of the guide rod 41 is provided on the machine 1. The guiding structure includes a slider 42 installed at both ends of the guide rod 41, and the machine 1 is provided with two second slide rails 43 perpendicular to the guide rod 41, and the slider 42 is slidably arranged on the second slide rail 43.

[0042] A separation mechanism for driving the two adjacent supporting groups 3 to move away from each other is provided between the two adjacent supporting groups 3, and a distance control mechanism for controlling the gap between the two adjacent supporting groups 3 is provided between the two adjacent supporting groups 3.

[0043] At the same time, the machine 1 is provided with a grinding head 5 and a robot arm 23 for driving the grinding head 5 to move between two distant supporting groups 3. The robot arm 23 can also be a two-axis robot arm 23 or a three-axis robot arm 23. Its function is to drive the high-speed rotating grinding head 5 to move along the longitudinal cutting seam to grind the edges of the cut LCD screen.

[0044] After such arrangement, when using the cutting device of the present application, first place the large LCD screen on the table 1, and adjust the position of the supporting table 31 according to the size of the small LCD screen to be cut, so that one small LCD screen planned to be cut corresponds to at least one supporting table 31, and then start the external negative pressure vacuum device, so that the supporting table 31 adsorbs and fixes the LCD screen with the help of the adsorption holes 311 thereon, and then cuts the large LCD screen through the longitudinal blade wheel 21 to divide it into multiple longitudinal long LCD screens supported and fixed by multiple supporting groups 3.

[0045] Subsequently, the separation mechanism separates the two adjacent longitudinal long liquid crystal screens, and the distance control mechanism controls the distance gap between the two, and then the grinding head 5 is started to grind the long sides of the longitudinal long liquid crystal screen to reduce the burrs on the longitudinal long sides of the liquid crystal screen, and avoid the occurrence of undesirable phenomena such as edge collapse, breakage or sawtooth caused by the stress concentration at the burrs in the liquid crystal screen during horizontal cutting due to the presence of burrs. The cutting quality when cutting first longitudinally and then transversely can be improved to a certain extent, and the yield rate of display screen cutting products can be improved.

[0046] Moreover, gaps are formed between the multiple longitudinal strips of LCD screens after longitudinal cutting, so that when the transverse cutting wheel 22 performs transverse cutting, only a "T"-shaped intersecting incision is formed on the long side of the longitudinal strip of LCD screen. Compared with the "X"-shaped intersecting incision produced by directly performing transverse cutting after longitudinal cutting in the current cutting process, the stress in the LCD screen can be released to a certain extent, making the probability of edge collapse of the LCD screen at the intersection lower, and thus the yield of the display screen cutting products can be improved to a certain extent.

[0047] Specifically, refer to Figure 1 , Figure 2 and Figure 3 The distance control mechanism includes a first connecting rod 61 and a second connecting rod 62 respectively hinged on adjacent ends of two laterally adjacent supporting platforms 31, a sliding sleeve 63 is hinged between the adjacent first connecting rods 61 and second connecting rods 62, and a distance control rod 71 parallel to the guide rod 41 is commonly penetrated through a plurality of sliding sleeves 63 in the same longitudinal direction, and a plurality of limit joints 72 corresponding to the plurality of sliding sleeves 63 are fixedly connected to the distance control rod 71; in the initial state, there is an angle between the first connecting rod 61 and the second connecting rod 62 on the sliding sleeve 63, and the limit joint 72 is located on the inner angle side of the angle.

[0048] The machine 1 is provided with a distance control assembly for adjusting the longitudinal position of the distance control rod 71. The distance control assembly includes slides 73 provided at both ends of the distance control rod 71. The machine 1 is provided with two first slide rails 74 perpendicular to the distance control rod 71. The slide 73 is slidably provided on the first slide rails 74. One end of the distance control rod 71 slides through one of the slides 73, and the other end is threaded through the other slide 73. A hand wheel or a driving motor is provided at one end of the distance control rod 71 threaded through the slide 73. In this embodiment, a hand wheel is provided at the end of the distance control rod 71, and a locking nut 75 is threadedly sleeved on one end of the distance control rod 71 close to the slide 73 screwed thereto, so as to fix the distance control rod 71 after adjusting the position of the limit joint 72. The first slide rail 74 and the second slide rail 43 can be the same slide rail.

[0049] In this way, when the spacing mechanism drives two adjacent support groups 3 to move away from each other, the first connecting rod 61 and the second connecting rod 62 on each relative support platform 31 in the two support groups 3 respectively pull the corresponding sliding sleeve 63 to slide on the control rod 71 until the sliding sleeve 63 moves to abut against the limit joint 72. At this time, the sliding sleeve 63 cannot slide on the control rod 71 toward the limit joint 72, that is, the distance between two laterally adjacent support platforms 31 in the two support groups 3 cannot be further increased, that is, the distance between the two longitudinal long LCD screens is limited, so that under the action of the spacing mechanism, the distance between the two adjacent long LCD screens after being cut can always be maintained at the set distance.

[0050] In this process, by turning the hand wheel to rotate the distance control rod 71 on the two slides 73, the positions of the multiple limit joints 72 on the distance control rod 71 between the two slides 73 can be adjusted, that is, the spacing between the two longitudinal long liquid crystal screens fixed on the two groups of support groups 3 can be preset, and the adjustment is relatively convenient. In addition, since the distance control rod 71 is provided with the slide 73 and the first slide rail 74, when the two groups of support groups 3 move away from each other, the distance control rod 71 can also move with the longitudinal long liquid crystal screens on the support group 3, and always keep the control of the spacing between the two adjacent longitudinal long liquid crystal screens, so that the consistency of the spacing control of all longitudinal long liquid crystal screens can be achieved to ensure the horizontal cutting effect.

[0051] In order to ensure the stability of the slide 73 after it contacts the limit joint 72, refer to Figure 1 and Figure 4, one of the two adjacent sides of the limit joint 72 and the adjacent sliding sleeve 63 is provided with a cone top 631, and the other is provided with a cone groove 721 adapted thereto. In this embodiment, the cone top 631 is fixed to the sliding sleeve 63, and the cone groove 721 is provided on the limit joint 72, and the cone top 631 and the cone groove 721 are coaxial with the distance control rod 71. In this way, when the distance between two laterally adjacent supporting platforms 31 is enlarged to a preset value, the cone top 631 on the sliding sleeve 63 is embedded in the cone groove 721 on the limit joint 72, and the contact area between the sliding sleeve 63 and the limit joint 72 is greatly increased, which can greatly avoid the possibility of circumferential shaking between the two, and further ensure the stability of the distance between two laterally adjacent longitudinal strip LCD screens.

[0052] In addition, refer to Figure 1 , Figure 2 and Figure 3 The above-mentioned separation mechanism includes a first magnetic body 81 and a second magnetic body 82 respectively arranged on adjacent ends of two laterally adjacent support platforms 31, and the first magnetic body 81 and the second magnetic body 82 magnetically repel each other, that is, the two magnetic poles are the same. And, more specifically, in order to avoid the magnetic repulsion between the first magnetic body 81 and the second magnetic body 82 during the cutting process of the longitudinal cutter wheel 21, that is, the two laterally adjacent support platforms 31 are pushed away from each other, which may cause the adjacent two longitudinal long strips of LCD screens not to be separated according to the cutting seam.

[0053] To this end, it is further configured that at least one of the first magnetic body 81 and the second magnetic body 82 is an electromagnet, for example, one is an electromagnet and the other is a permanent magnet, or both are electromagnets; and the longitudinal cutter wheel 21 is connected to a first controller, and the electromagnet is controlled and connected to the first controller; when the longitudinal cutter wheel 21 completes the longitudinal cutting of the LCD screen, the first controller controls the electromagnet to be energized and magnetized.

[0054] In this way, when the longitudinal blade wheel 21 completes the longitudinal cutting, the first controller controls the electromagnet to be energized. At this time, the first magnetic body 81 and / or the second magnetic body 82 are magnetized, so that a magnetic repulsion force is generated between the first magnetic body 81 and the second magnetic body 82, so that the two laterally adjacent support platforms 31 move away from each other, and the distance between the two support platforms 31 is limited by the controlled distance mechanism, so that the longitudinal long strip of LCD screen after cutting can be unfolded in an orderly manner, which is convenient for horizontal cutting.

[0055] Furthermore, one of the plurality of supporting groups 3 is fixed on the machine table 1, so that the plurality of supporting tables 31 eventually tend to a constant position; and the rotation direction of the transverse blade wheel 22 when cutting the LCD screen points to the supporting group 3 fixed on the machine table 1. For example, when the transverse blade wheel 22 rotates to cut a longitudinally long strip of LCD screen, the rotating transverse blade wheel 22 makes the longitudinally long strip of LCD screen tend to approach the supporting group 3 fixed on the machine table 1.

[0056] In this way, when the transverse blade wheel 22 is cutting the transverse cutting seam, the cut longitudinal strip LCD screen can have a tendency to approach the supporting group 3 fixed on the machine table 1, that is, the spacing between the longitudinal strip LCD screen and the several longitudinal strip LCD screens between the supporting group 3 has a tendency to decrease. This tendency needs to overcome the magnetic repulsion between the multiple first magnetic bodies 81 and the second magnetic bodies 82, so that the longitudinal strip LCD screen can form a floating effect on the machine table 1.

[0057] Specifically, the longitudinally long LCD screen can be shaken along the transverse cutting seam during the process of being transversely cut. On the one hand, such shaking can help guide the cracks of the LCD screen to expand evenly and straightly along the predetermined cutting line direction, thereby reducing irregular edges and cracks of the LCD screen after cutting, and improving the cutting accuracy; on the second hand, during the cutting process, stress may be generated inside the LCD screen, and the slight shaking of the LCD screen itself can disperse these stresses and reduce cracks not on the cutting line caused by stress concentration; on the third hand, during the cutting process, if the rotation speed of the transverse blade wheel 22 changes suddenly or becomes unstable, the LCD screen breaks too suddenly or quickly along the cutting line, which may cause edge collapse, and the slight shaking of the LCD screen itself can make the break of the LCD screen smoother and reduce the edge collapse phenomenon; on the fourth hand, if there are tiny defects or uneven stress distribution on the LCD screen, the cracks during cutting may deviate from the predetermined cutting line to form irregular cracks, and the slight shaking of the LCD screen itself can help adjust these non-uniformities and reduce the occurrence of unexpected cracks. Therefore, the floating cutting effect of the horizontal cutter wheel 22 on the longitudinal long liquid crystal screen can greatly reduce the edge chipping, breakage or sawtooth defects of the liquid crystal screen when it is completely cut, thereby improving the product yield.

[0058] The implementation principle of a cutting device for producing LCD screen modules in the embodiment of the present application is as follows:

[0059] When using the cutting equipment of the present application, a large LCD screen is first placed on the table top of the machine 1, and then divided into corresponding areas through multiple supporting tables 31, and the external negative pressure vacuum equipment is started to allow the supporting table 31 to adsorb and fix the LCD screen, and then the large LCD screen is cut by the longitudinal blade wheel 21 to divide it into multiple longitudinal long LCD screens supported and fixed by multiple supporting groups 3.

[0060] Subsequently, the first magnetic body 81 and the second magnetic body 82 drive the two adjacent longitudinal long liquid crystal screens to move away from each other, and control the distance gap between the two with the cooperation of the sliding sleeve 63 and the limit joint 72, and then start the grinding head 5 to grind the long sides of the longitudinal long liquid crystal screen, which can reduce the burrs on the longitudinal long sides of the liquid crystal screen, and avoid the occurrence of undesirable phenomena such as edge collapse, breakage or sawtooth caused by the stress concentration at the burrs in the liquid crystal screen during horizontal cutting due to the presence of burrs. The cutting quality when cutting first longitudinally and then transversely can be improved to a certain extent, and the yield rate of display screen cutting products can be improved.

[0061] Moreover, gaps are formed between the multiple longitudinal strips of LCD screens after longitudinal cutting, so that when the transverse cutting wheel 22 performs transverse cutting, only a "T"-shaped intersecting incision is formed on the long side of the longitudinal strip of LCD screen. Compared with the "X"-shaped intersecting incision produced by directly performing transverse cutting after longitudinal cutting in the current cutting process, the stress in the LCD screen can be released to a certain extent, making the probability of edge collapse of the LCD screen at the intersection lower, and thus the yield of the display screen cutting products can be improved to a certain extent.

[0062] Furthermore, when the transverse blade wheel 22 is cutting the transverse cutting seam, the longitudinally long LCD screen can be swayed along the transverse cutting seam during the transverse cutting process to create a floating effect, thereby reducing irregular edges and cracks of the LCD screen after cutting and improving cutting accuracy; and can disperse the internal stress of the LCD screen and reduce cracks that are not on the cutting line due to stress concentration; and through the slight shaking of the LCD screen itself, the fracture of the LCD screen can be smoother and the edge collapse phenomenon can be reduced, thereby greatly reducing the edge collapse, breakage or jaggedness of the LCD screen when it is completely cut, thereby improving product yield.
