[0002] During the production process of display screens, the display screens need to be laser cut to form rounded corners, speaker holes, camera holes, etc. During the cutting operation, the cutting equipment needs to fix the display screen by adsorbing it through the jig mounted on it. In order to process display screens of different sizes, the cutting equipment needs to be equipped with jigs with adsorption holes of different sizes. The jigs need to be replaced and leveled accordingly before changing the display screen to be processed, which is very inconvenient.

[0003] At the same time, during the cutting operation, waste debris will be generated on the surface of the jig. The debris left on the jig can easily scratch the next display screen, or make it impossible to place the next display screen flat, affecting processing.

It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0034] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0036] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] This embodiment provides a display screen cutting jig, which can absorb the display screen to facilitate processing of the display screen, and the display screen cutting jig is convenient for collecting debris scattered thereon, and is therefore particularly suitable for display screen cutting operations.

[0038] See also Figure 1 , Figure 2 and Figure 3 The display screen cutting jig includes a box body 1, a substrate 2 and an adsorption plate 3. The box body 1 has an opening 101. The substrate 2 is covered on the opening 101 and has a first stepped groove 201 running through it. The adsorption plate 3 is detachably covered on the first stepped groove 201 to form a box cavity with the box body 1 and the substrate 2. The adsorption plate 3 has adsorption holes 31 and chip collection holes 32 extending to its surface. The adsorption hole 31 is connected to a vacuum air source so that the surface of the adsorption plate 3 forms a first adsorption portion for adsorbing the display screen. The chip collection hole 32 is connected to the vacuum air source through the box cavity and corresponds to the cutting area of ​​the display screen, so that the box cavity can collect debris generated by the cutting of the display screen.

[0039] By means of the above structure, the display screen cutting jig can be equipped with multiple adsorption plates 3, and each adsorption plate 3 can be configured to have adsorption holes 31 and chip collection holes 32 with different opening positions and numbers, so as to adapt to display screens of different shapes and / or different cutting parts. Therefore, before cutting different display screens, it is only necessary to simply replace the adsorption plate 3 without completely replacing the display screen cutting jig, which greatly saves the time for replacement operations and reduces the difficulty of leveling and replacement operations.

[0040] At the same time, during the cutting operation, in addition to the adsorption holes 31, the vacuum air source also continuously provides negative pressure suction to the box cavity, so that negative pressure suction is formed at the chip collection holes 32 corresponding to the cutting area of ​​the display screen, and the debris generated by the cutting can be directly sucked into the box cavity by the air, or the debris sputtered to other areas of the substrate 2 can be manually moved to the chip collection holes 32 and then fall into the box cavity, so as to keep the surface of the substrate 2 and the adsorption plate 3 and even the working processing environment clean for a long time.

[0041] Specifically, see Figure 2 Combined with Figure 3 and Figure 4 In this embodiment, the box body 1 includes a bottom plate 11 and a plurality of wall plates 12 mounted on the bottom plate 11, and each wall plate 12 is connected end to end to enclose the bottom plate 11 to form an opening 101 with an opening facing upward. The heights of the wall plates 12 are consistent, so that the top surfaces of the wall plates 12 are coplanar and form a placement plane 102 for carrying the substrate 2. The substrate 2 with the first stepped groove 201 is covered on the placement plane 102, and the side of the first stepped groove 201 with a larger groove width is set upward, so that the adsorption plate 3 can overlap with the first stepped groove 201 and be covered on the substrate 2, so as to form a closed box cavity after being fastened by fasteners such as screws. Preferably, a plurality of ribs 13 for auxiliary support of the substrate 2 can be further provided in the box body 1, so that the substrate 2 can be reliably placed.

[0042] In order to ensure that the display screen can be cut accurately, it is necessary to ensure that the display screen can be placed in a horizontal position before the cutting operation, that is, the surface of the adsorption plate 3 on which the display screen is placed must be parallel to the horizontal plane. In this embodiment, the adsorption plate 3 is placed on the substrate 2, so the display screen can be indirectly adjusted and ensured to be placed horizontally by adjusting the posture of the substrate 2 or the box body 1.

[0043] As mentioned above, the box body 1 is a base structure fixed to the cutting device, and it is not easy to adjust its posture. Therefore, a better solution is to achieve the above-mentioned purpose of placing the display screen horizontally by adjusting the posture of the substrate 2.

[0044] Specifically, at least three nonlinearly arranged top screw holes 21 can be provided on the base plate 2, and a top screw (not shown in the figure) is threaded into each top screw hole 21. After being rotated, the top screw can extend out of the top screw hole 21 and abut against the box body 1 to adjust the flatness of the base plate 2; the base plate 2 is also provided with countersunk holes 22 near each top screw hole 21 for facilitating locking the base plate 2 and the box body 1.

[0045] With the above structure, after the top screws respectively arranged in the at least three nonlinearly arranged top screw holes 21 abut against the box body 1, the bottoms of the top screws can cooperate to form the foot structure of the base plate 2. The top screws are twisted to adjust the posture of the base plate 2, so that the adsorption plate 3 is in a horizontal posture. When the adsorption plate 3 is in a horizontal posture, the base plate 2 and the box body 1 are locked by countersunk screws, so that the adsorption plate 3 is positioned in a horizontal posture.

[0046] In this embodiment, a groove with a "I" or "X" shape that can be easily engaged with a tool can be provided on the top of the top screw, so that the top screw can be twisted by the tool. The top screw can adjust the posture of the base plate 2 by abutting against the top surfaces of the wall plates 12 and even the rib plates 13 of the box body 1. At the same time, threaded holes corresponding to the countersunk holes 22 on the base plate 2 can be provided on the top surfaces of the wall plates 12 and the rib plates 13 of the box body 1, so that the countersunk screw can be screwed into the threaded countersunk hole 22 and the threaded hole in turn to lock the base plate 2 and the box body 1.

[0047] Optionally, the above-mentioned top screw holes 21 and countersunk holes 22 can be set at the locations where the base plate 2 is connected to each wall panel 12 and rib plate 13 of the box body 1, and the number of countersunk holes 22 set near each top screw hole 21 is not limited to one, so that with the cooperation of multiple top screws, the posture of the base plate 2 and the adsorption plate 3 can be more accurately adjusted.

[0048] The surface of the substrate 2 and the surface of the adsorption plate 3 are preferably arranged in the same plane, so that when the substrate 2 is adjusted to a horizontal posture, the adsorption plate 3 can also be in a horizontal posture, which is convenient for leveling and can keep the display cutting jig beautiful. Of course, in other optional embodiments, the surfaces of the substrate 2 and the adsorption plate 3 can also be arranged in parallel, which also has the above-mentioned effect.

[0049] As a commonly used jig in the display processing industry, the structure of the adsorption hole 31 and the vacuum air path in the adsorption plate 3 is not described in detail here. However, it should be noted that in this embodiment, a through groove connected to the vacuum air source can be directly opened on the bottom plate 11 or the wall plate 12 of the box body 1, so that the vacuum air source device can be started during the cutting operation and the box body 1 can be continuously in a negative pressure state, thereby forming a negative pressure suction force at the chip collection hole 32.

[0050] See also Figure 2In this embodiment, the box body 1 may further include a drawer 14 that can be inserted into the box cavity, and the drawer 14 corresponds to the chip collecting hole 32, so that the chips can be collected more conveniently. The drawer 14 and the box body 1 can be locked by a screw connection component (such as a screw with a handle), so that when the drawer 14 is pushed into the box body 1, the drawer 14 can be tightly locked to the box body 1, so that the box cavity has a better airtight structure. At the same time, a plurality of through holes can be opened on the side wall of the drawer 14 located inside the box body 1, so that the airflow flowing into the drawer 14 from the chip collecting hole 32 can be dispersed and flowed out through each through hole, so as to prevent the airflow flowing through the drawer 14 from being too concentrated and entraining the chips out of the drawer 14.

[0051] More preferably, in order to prevent smaller debris from being brought into the vacuum air source device, a filter 15 can be provided at the through slot opened on the box body 1, that is, the box body 1 can be connected to the vacuum air source through the filter 15 provided therein, so that the debris is retained in the box cavity.

[0052] When the above-mentioned cutting operation is performed on the display screen, the display screen being cut may have accessories such as FPC installed. If the softer FPC extending out of the display screen is not fixed, the FPC may be damaged or even damaged by the laser during the cutting operation under the action of the airflow. In addition, in the case where some FPCs overlap with the cutting position of the display screen glass substrate 2, it is necessary to pull the FPC in the opposite direction and fix it before the cutting operation can be performed. To this end, in the present embodiment, an adsorption block 4 that can move toward or away from the first adsorption portion may also be provided on the adsorption plate 3, and a second adsorption portion is formed on the adsorption block 4, and the second adsorption portion can adsorb the FPC extending outward from the display screen to fix the FPC during the cutting operation. At the same time, the adsorption block 4 that can move toward or away from the first adsorption portion is suitable for fixing FPCs of different sizes on different display screens.

[0053] Specifically, see Figure 4 The adsorption plate 3 has a second stepped groove 301 which is not connected to the box cavity. The second stepped groove 301 extends away from the first adsorption portion. The two adsorption blocks 4 are movably overlapped on the second stepped groove 301 so as to be able to move along the extension direction of the second stepped groove 301 respectively.

[0054] A plurality of positioning holes arranged at intervals may be provided on the step surface of the second step groove 301, and a strip groove may be provided at the two edges of each adsorption block 4 for overlapping with the step surface of the second step groove 301, respectively, and the strip groove may be connected with the corresponding positioning hole and fastened by a fastener, so that the position of the adsorption block 4 can be flexibly adjusted and then locked. It should be noted that in other optional embodiments, the number of adsorption blocks may also be other numbers, such as one, three, etc., which are not limited here.

[0055] In order to further adapt to FPCs of different sizes for different display screens, in addition to configuring the adsorption block 4 to be movable, a second adsorption portion with a variable suction force generating position and quantity can be configured on the adsorption block 4. Figure 5 and Figure 6 The adsorption block 4 has an air passage 41 formed inward from its end surface, and the air passage 41 is connected to a vacuum air source. The surface of the adsorption block 4 has a plurality of air holes 42 connected to the air passage 41. In each of the air holes 42, an air nozzle 43 for forming a second adsorption portion is installed in the air hole 42 corresponding to the FPC of the display screen, and a sealing member 44 is provided in the remaining air holes 42.

[0056] By means of the above structure, for different display screens, the air nozzle 43 and the blocking member 44 can be selectively installed in each air hole 42 to form a second adsorption portion with variable suction force generating position and quantity. Preferably, in order to facilitate the adjustment of the position of the air nozzle 43 and the blocking member 44, the air nozzle 43 and the blocking member 44 can be screwed to the air hole 42.

[0057] Optionally, the adsorption hole 31, the air duct 41 and the box cavity are independently connected to the vacuum air source so that the suction can be adjusted separately. For example, after cutting a display screen, if there are debris left on the substrate 2 or the adsorption plate 3, the connection between the adsorption hole 31 and the air duct 41 and the vacuum air source can be closed, and the connection between the box cavity and the vacuum air source can be retained, that is, only the chip collection hole 32 has suction, which is convenient for the operator to remove the display screen on the adsorption plate 3 and use tools to clean the substrate 2 and the adsorption plate 3. At the same time, since the suction required for the fixed rigid display screen and the flexible FPC is different, the vacuum air source can adjust the suction of the adsorption hole 31 and the air duct 41 separately through valves on independent air paths. In this embodiment, the adsorption hole 31 and the air duct 41 can be respectively connected to the external vacuum air source through two air path joints penetrating the wall panel 12 of the box body 1.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
