The base 2 is used for mounting the fixed platform 3 , the movable platform 4 and the track unit 6 . The structure of the base 2 is not limited, as long as it can be erected and installed by the above-mentioned components.

The fixed platform 3 is fixedly disposed above the base 2 , and includes an upward fixed surface 31 for supporting and contacting the display panel 1 , and a plurality of air holes 32 formed on the fixed surface 31 .

The movable stage 4 is arranged on one side of the fixed stage 3 along a first direction 81 , and can reciprocate relative to the fixed stage 3 along the first direction 81 to adjust a distance from the fixed stage 3 . The movable platform 4 includes an upward bearing surface 41 for supporting and contacting the display panel 1 , and a plurality of air holes 42 formed on the bearing surface 41 . In this embodiment, the first direction 81 is a left-right direction, and the movable stage 4 can move left and right relative to the fixed stage 3 . The movable platform 4 can move left and right on the base 2 through the cooperation of transmission rails, conveyor belts, chains or other transmission mechanisms. Since the structural design of driving a component to reciprocate in mechanical equipment is a known technology, and it is not the focus of the improvement of the utility model, so it will not be described again.

Referring to FIGS. 2 , 3 , and 4 , the expansion carrier 5 is also disposed above the base 2 , and is disposed on a side of the fixed carrier 3 away from the movable carrier 4 along the first direction 81 . The expansion platform 5 includes a pivot side 51 pivotally connected to the fixed platform 3 , and a movable side 52 opposite to the pivot side 51 and spaced apart from the pivot side 51 along the first direction 81 . The expansion carrier 5 can pivot relative to the fixed carrier 3 , and then move between a loading position as shown in FIGS. 2 and 4 and a retracted position as shown in FIG. 3 . When in the bearing position, the expansion platform 5 is horizontal and can cooperate with the fixed platform 3 and the movable platform 4 for placing the display panel 1 , and at this time the movable side 52 is far away from the fixed platform 3 And it is at the same height as the pivotal side 51 . When the expansion platform 5 is in the retracted position, it extends approximately upright and closes against the side of the fixed platform 3 . At this time, the movable side 52 is close to the fixed platform 3 and is located on the pivot side 51 . below.

The rail unit 6 is located between the fixed platform 3 and the movable platform 4 , and includes a first rail 61 above the display panel 1 and a second rail 62 below the display panel 1 . Both the first track 61 and the second track 62 extend along a second direction 82 transverse to the first direction 81 . Specifically, the second direction 82 in this embodiment is perpendicular to the first direction 81 , and the second direction 82 refers to the front-to-back direction.

The cutter unit 7 is located between the fixed stage 3 and the movable stage 4 , and can move along the second direction 82 for cutting the display panel 1 . Specifically, the cutter unit 7 includes a first cutter 71 and a second cutter 72 opposite to each other at intervals up and down. The first cutter 71 is mounted on the first rail 61 so as to be movable along the second direction 82 , and is used for cutting the upper substrate 11 of the substrates 11 of the display panel 1 . The second cutter 72 is mounted on the second track 62 movably along the second direction 82 , and is used for cutting the lower substrate 11 of the substrates 11 of the display panel 1 . Both the first cutter 71 and the second cutter 72 can be driven to move up and down, so as to be close to the display panel 1 when cutting is required.

Referring to Figures 1, 3, and 5, when the utility model is used, the movable carrier 4 is driven to move to an appropriate position according to the size of the display panel 1. If the size of the display panel 1 is small, it is not necessary to use the The expansion carrier 5 can be placed in the retracted position. Then place the display panel 1 so that the display panel 1 can be supported by the movable platform 4 and the fixed platform 3 at the same time, and can be placed completely horizontally without any part being bent downward or hanging down. Then use an air pump not shown in the figure to connect the air holes 32, 42 through the pipeline and pump air, so as to generate negative pressure in the pipeline and the air holes 32, 42, so that the display panel 1 can be adsorbed and fixed. . The first cutter 71 and the second cutter 72 are driven to move along the second direction 82, so as to respectively cut a slit 111 extending along the second direction 82 on the substrate 11 of the display panel 1 (Fig. 5). The operator can stand on the side of the fixed platform 3 away from the movable platform 4 and break the display panel 1 along the cutout 111 to obtain a display panel 10 of a predetermined size ( FIG. 4 ).

Referring to Figures 4 and 5, when the utility model is used to cut a display panel 1 with a larger size, the movable carrier 4 can be moved away from the fixed carrier 3 relative to the state shown in Figure 3, and the expansion carrier 5 can be pivoted Turning to the bearing position shown in Figure 4, the movable carrier 4, the extended carrier 5 and the fixed carrier 3 together form a larger carrier platform, so that the display panel 1 of a larger size can be placed flatly, Therefore, the present invention can also be applied to the display panel 1 with a larger cutting size. At this time, the operator can stand on the movable side 52 of the expansion carrier 5 and break the display panel 1 along the cutout 111 .

To sum up, when the expansion carrier 5 is located at the bearing position, it can be matched with the fixed carrier 3 and the movable carrier 4 to form a larger bearing area, so whether it is a small size or a larger size All display panels 1 are suitable for cutting by the utility model. The expansion stage 5 located at the bearing position can help to support the side part of the display panel 1, avoiding this part to hang down on the side of the fixed stage 3, and then achieve a more comprehensive support for the display panel 1, so that The display panel 1 as a whole can be placed horizontally and flatly without any part bending, so the cutting accuracy and yield can be improved, and the generation of defective cutting products can be reduced to reduce the cost. When the expansion carrier 5 is not in use, it can be folded so that it is more convenient for operators to approach the fixed carrier 3 to perform the operation of breaking the display panel 1, so that the overall volume of the utility model can be reduced, and it is easy to use. Very convenient.
