As shown in fig. 1 to 3, a system 100 for manufacturing a display panel includes: the cutting unit 10 may form a plurality of first cutting lines V and a plurality of second cutting lines H on the display mother board 200, the plurality of first cutting lines V and the plurality of second cutting lines H intersect to respectively define the sizes of the plurality of display panels 210, in this embodiment, the display panels 210 are rectangular, the extending direction of the first cutting lines V is the same as the extending direction of the short sides of the rectangle, the extending direction of the second cutting lines H is the same as the extending direction of the long sides of the rectangle, and the plurality of first cutting lines V and the plurality of second cutting lines H intersect perpendicularly. When the cutting is completed, the display mother substrate 200 is still a complete sheet, the display panels 210 are substantially connected without being separated, and a plurality of cutting lines are formed only on the upper and lower surfaces of the display mother substrate 200.
Referring to fig. 2, in order to facilitate the separation of the display panels 210 from the display mother board 200 by the splitting unit 20 without damaging the display panels 210, an edge margin region is disposed at an edge of each display panel 210, and preferably, the edge margin region is disposed around the display panel 210. Since the display panel 210 is rectangular, the border regions 221, 222, 223, and 224 are respectively disposed on four sides of the display panel 210, and the border regions 221, 222, 223, and 224 and the display panel 210 form the first separation unit 210 ', that is, first, the separation device 300 (shown in fig. 4) of the splitting unit 20 separates the first separation unit 210' from the display mother board 200; next, the separating device 300 (as shown in fig. 4) removes the edge material regions 221, 222, 223, and 224 of the first separating unit 210', so as to obtain the display panel 210 with the target size, wherein a first cutting line V and a second cutting line H are disposed between the display panel 210 and the edge material regions 221, 222, 223, and 224.

Since the top surface of the buffer bar 22 protrudes from the upper surface of the second platform 21, the buffer bar 22 will lift the display mother board 200, when the first cutting line V on the display mother board 200 corresponds to the top surface of the buffer bar 22, due to the gravity, the portions of the display mother board 200 located at both sides of the first cutting line V will tend to move (i.e. sag) toward the upper surfaces of the first platform 11 and the second platform 21, thereby increasing the degree of splitting of the display mother board 200 by the first cutting line V, and facilitating the subsequent separation device 300 (as shown in fig. 4) to separate the display panel 210. The cross section of the buffer strip 22 is, for example, in a shape with a narrow top and a wide bottom, such as a triangle, a trapezoid, etc., i.e., the width of the top surface of the cross section of the buffer strip 22 is smaller than the width of the bottom surface of the buffer strip 22, and the top surface and the bottom surface are opposite, wherein the buffer strip 22 is, for example, foam, silica gel, etc. In this embodiment, the buffer bar 22 is disposed at an end portion of the second platform 21, and the end portion is adjacent to the first platform 11, and the motherboard 200 is shown to be transferred from the end portion to the second platform 21, but not limited thereto.

Or, there is no gap between the first platform 11 and the second platform 21, and the buffer strip is disposed at the junction of the first platform 11 and the second platform 21, depending on the actual requirement.

The pressing unit 320 includes a sliding member 324, a connecting rod 321, an elastic member 325, and a pressing plate 326, wherein the sliding member 324 is slidably connected to one end of the second supporting arm 312, the connecting rod 321 is disposed between the sliding member 324 and the pressing plate 326, the sliding member 324 slides relative to the second supporting arm 312 to drive the connecting rod 321 and the pressing plate 326 to move together, the elastic member 325 is sleeved on the connecting rod 321, a first end of the elastic member 325 abuts against a first surface of the sliding member 324, a second end of the elastic member 325 abuts against a second surface of the pressing plate 326, the first surface is opposite to the second surface, the pressing plate 326 includes a first pressing portion 322 and a second pressing portion 323 connected to each other, an included angle C is formed between the first pressing portion 322 and the second pressing portion 323, the included angle C is 0 ° to 180 °, preferably 90 ° to 120 ° in this embodiment, the included angle C between the first pressing portion 322 and the second pressing portion is 90 °, that is an inverted L type pressing plate 326, a second end of the elastic member 325 abuts against a second surface of the pressing portion 326, that the second end of the elastic member 325 abuts against an upper surface of the first pressing portion 322, the pressing portion 322, a side wall 321 of the pressing portion 322, and a side wall 3231 of the pressing portion 32131, and a side wall 32231, and a side wall.
With reference to fig. 5, the sliding member 324 has a through hole (not shown), the third end of the connecting rod 321 passes through the through hole, and the stopper 3211 is disposed at the third end of the connecting rod 321 to prevent the connecting rod 321 and the sliding member 324 from separating from each other; the connecting rod 321 further includes a fourth end, which is fixed to the second surface of the first pressing portion 322 of the pressing plate 326. Preferably, the second supporting arm 312 is further provided with a scale 313, and when the sliding member 324 is required to be adjusted to drive the pressing plate 326 to a designated position according to the target size of the display panel 210, so that the first pressing portion 322 and the second pressing portion 323 of the pressing plate 326 respectively correspond to different pressing positions, the pressing plate of the pressing unit 320 can be rapidly moved to the designated position by the arrangement of the scale 313. The sliding block or the sliding groove is disposed on the sliding member 324, and the corresponding sliding groove or the sliding block is disposed on the second support arm 312, and the sliding groove and the sliding block are matched with each other to enable the sliding member 324 to slide relative to the second support arm 312. Further, the slider 324 includes an adjustment knob 3241, and when the adjustment knob 3241 is loosened so that the slider 324 can slide with respect to the second support arm 312, and when the slider slides to the above-mentioned specified position, the adjustment knob 3241 is tightened so that the slider 3241 is fixed at the specified position. In other embodiments, the slider 324 can be directly slid relative to the second support arm 312 by rotating the adjusting knob 3241.
In this embodiment, the first pressing portion 322 is used to separate the border regions 221 to 224 from the first separating unit 210 'to obtain the display panel 210 with the target size, and the second pressing portion 323 is used to press other regions surrounding the border regions 221 to 224, so that the first separating unit 210' is separated from the display mother board 200.
To clearly understand the separation process of the first pressing portion 322 and the second pressing portion 323, please refer to fig. 5 to 6C. In fig. 5 and fig. 6C, the two pressing units 320 on the second supporting arm 312 of the bracket 310 are illustrated as separating the edge material areas 222 and 224, but it should be noted that the process of separating the edge material areas 221 and 223 by the two pressing units 320 on the first supporting arm 311 of the bracket 310 is similar to the schematic diagram of the process of separating the edge material areas 222 and 224.
As shown in fig. 6A, the separating device 300 is moved to a position above the second platform 21 (shown in fig. 2), the display mother board 200 is carried on the second platform 21, and a plurality of first cutting lines V and a plurality of second cutting lines H are formed on the display mother board 200 and are staggered with each other; the adsorption unit 330 is driven to align with the center of the first separation unit 210 ' to be separated, that is, the center of the first separation unit 210 ' is, for example, the center of the display panel 210, and the adsorption unit 330 adsorbs and fixes the first separation unit 210 '. According to the target size of the display surface 210, the sliding member 324 is moved to slide to a designated position relative to the second supporting arm 312, when the sliding member 324 is located at the designated position, the vertical projection of the first pressing portion 322 on the display panel 200 falls in the border area 224, and the vertical projection of the second pressing portion 323 on the display panel 200 falls in an area adjacent to the border area 224 (the area adjacent to the border area 224 may be, for example, the border area in the separation unit adjacent to the first separation unit 210'), and at this time, the elastic member 325 is in a compressed state. Preferably, the second pressing portion 323 only presses the edge material region of another separating unit adjacent to the edge material regions 222 and 224, that is, the second pressing portion 323 does not contact the edge material regions 222 and 224 of the first separating unit 210' and does not contact the display panel in the adjacent separating unit, so that the second pressing portion 323 does not contact the display panel 210 all the time when the separating device 300 separates the display panel 210 from the display mother board 200, thereby effectively preventing the second pressing portion 323 from pressing the display panel 210.
As shown in fig. 6B, the suction unit 330 is driven to move towards a direction away from the display mother board 200, so that the first separating unit 210' is separated from the display mother board 200, in the process, when the driving unit (not shown) drives the suction unit 330 to move towards a direction away from the display mother board 200, the second supporting arm 312 and the sliding member 324 respectively move towards a direction away from the display mother board 200, the sliding member 324 moves along the connecting rod 321 towards a direction away from the pressing plate 326 through the through hole, so that a distance between the first surface of the sliding member 324 and the second surface of the first pressing portion 322 is increased, that is, a distance between two ends of the elastic member 325 is increased, at this time, the elastic member 325 is changed from a compressed state to a first extended state, and due to an elastic force of the elastic member 325 itself, the second end of the elastic member 325 still abuts against the second surface of the first pressing portion. Continuing to drive the absorption unit 330 to move in a direction away from the display mother board 200, so that the rim charge regions 222 and 224 in the first separation unit 210' contact the first pressing portions 322 respectively, wherein the second ends of the elastic members 325 abut against the second surfaces of the first pressing portions 322, that is, the elastic members 325 exert a force in the direction of D1 on the first pressing portions 322, and the first pressing portions 322 can provide a pressing force in the direction of D1 to the rim charge regions 222 and 224; the driving unit drives the first separating unit 210 ' to move away from the display mother board 200, which is equivalent to the driving unit applying a force in the direction D2 to the display panel 210 in the first separating unit 210 ', and the direction D1 is opposite to the direction D2, so that when the rim charge areas 222 and 224 contact the first pressing portion 322, the rim charge areas 222 and 224 can be separated from the first separating unit 210 ' very easily under the interaction of the two forces in opposite directions, and the display panel 210 with the target size is obtained. In this embodiment, the first sidewalls 3221 (as shown in fig. 4) of the two first pressing portions 322 do not contact the display panel 210, i.e., the vertical projections of the first sidewalls 3221 also fall into the rim strip regions 222 and 224, respectively.
As shown in fig. 6C, after the edge material regions 222 and 224 are separated, since the first stretching state of the elastic member 325 is not a complete stretching state, the elastic force of the elastic member 325 continues to drive the sliding member 324 to move along the connecting rod 321 toward a direction away from the display mother board 200, so that the display panel 210 is further lifted above the first pressing portion 322, and preferably, the lower side surface of the display panel 210 may be higher than the second surface of the first pressing portion 322. Fig. 6C only shows that the display panel 210 is lifted to a position slightly higher than the second surface of the first pressing portion 322, but not limited thereto. In practical use, the relative position relationship between the second surface of the first pressing portion 322 and the display panel 210 can be set according to practical requirements. In this embodiment, the releasing of the elastic force of the elastic member 325 needs to be performed in cooperation with the lifting height of the suction unit 330, so as to avoid the abnormal separation caused by too fast releasing of the elastic force.
As can be seen from the above description, in the process of separating the display panel 210 by the separating apparatus 300 of the present invention, the first pressing portion 322 and the second pressing portion 323 of the pressing plate 226 do not contact the display panel 210, and the regions of the acting force applied by the first pressing portion and the second pressing portion 323 are all the rim charge regions surrounding the display panel 210, so that the pressure damage to the display panel 210 during the separating process is further reduced, and the separating damage can be effectively avoided.
The separator 300 further includes a driving unit (not shown) which is connected to the adsorption unit 330, and drives the adsorption unit 330 to move in an expansion and contraction manner, and the driving unit is, for example, a driving cylinder. Of course, in other embodiments of the present invention, the process of driving the absorption unit 330 to move toward the second direction can also be realized by the elastic force generated when the first elastic element 321 and the second elastic element 323 change from the compressed state to the extended state.
