Description
Technical Field
[0001] The utility model relates to the field of displays, and particularly to a sheet-breaking device for glass cutting in a display panel. Background Art
[0002] With the development of technology, display panels are widely used in commonly used electronic products in life, such as in-vehicle displays, laptop computers, or mobile phones, etc. In the production process of display panels, usually multiple display areas are made on a large-area mother board according to the needs of actual products, and then the display panels are cut into semi-finished products of small standard sizes according to each display area. After cutting, bait (or called surplus material) remains on each semi-finished display panel, which needs to be broken off.
[0003] Currently, when breaking the semi-finished display panels, usually two sheet-breaking methods are adopted: the chopping type for breaking the bait or the adsorption type for bending and breaking the bait. Both of these two sheet-breaking methods place the semi-finished display panel on the workbench, and the part to be sheet-broken extends beyond the edge of the workbench, and the semi-finished display panel is broken downward or upward by a breaking member. In the trend of narrow bezels or even borderless, the bait on each semi-finished display panel (generally located in the bezel area or adjacent to the bezel area) is getting narrower and narrower. Since the current bait has become narrower, for example, the minimum can reach 2.4 mm, if the original two sheet-breaking methods are still used, it is easy to generate debris during the sheet-breaking process, or there will be bad situations such as tail-shaped cracks or shell-shaped cracks on the semi-finished display panel, affecting the production yield.

Similar components in the drawings are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not be used to limit the protection scope of the present utility model.
[0023] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 shown is a top view of the sheet breaking device of the present utility model, Figure 2 shown is a side view of the sheet breaking device of the present utility model, Figure 3 shown is a schematic structural view of the sheet breaking component of the sheet breaking device of the present utility model. As Figure 1 and Figure 2As shown in the figure, the present utility model provides a sheet-breaking device 100, which includes a base 90, a carrier 10, a sheet-breaking assembly 20 and a control assembly 30. The carrier 10 is arranged on the base 90 for carrying a semi-finished display panel to be cut. The semi-finished display panel has a bait to be broken off. The carrier 10 has a first side 11, a second side 12 and a third side 13 which are connected to each other. The first side 11 is opposite to the third side 13. The sheet-breaking assembly 20 is arranged on the base 90 and adjacent to the second side 12 of the carrier 10. In one embodiment, the sheet-breaking assembly 20 is designed to be in contact with the carrier 10, that is, there is no gap between the sheet-breaking assembly 20 and the carrier 10 along the extension direction of the first side 11 / third side 13. The sheet-breaking assembly 20 has a sheet-breaking plate 21, and the sheet-breaking plate 21 has a groove 211. The groove 211 faces the carrier 10. The second side 12 has a first length L1, and the groove 211 has a second length L2. The first length L1 is equal to the second length L2. Along the extension direction of the second side 12, the control assembly 30 is arranged adjacent to at least one of the opposite sides of the sheet-breaking plate 21. The control assembly 30 is connected to the sheet-breaking assembly 20. The control assembly 30 has a first button 31 and a second button 32. When the first button 31 is pressed, the sheet-breaking assembly 20 is restricted to rotate only counterclockwise. When the second button 32 is pressed, the sheet-breaking assembly 20 is restricted to rotate only clockwise.
[0024] The semi-finished display panel includes a display panel body (which will be used as the display panel subsequently) and a bait to be broken off connected thereto. There is a pre-cutting line between the display panel body and the bait to be broken off. When the semi-finished display panel is placed on the carrier 10, at least part of the bait to be broken off extends beyond the second side 12 of the carrier 10 and extends into the sheet-breaking assembly 20. An operator can use the sheet-breaking device 100 of the present invention to break off the bait to be broken off from the semi-finished display panel along the pre-cutting line to process the required display panel.
[0025] In this embodiment, along the extension direction of the first side 11, the groove 211 has a first width W1, and the first width W1 is greater than or equal to the width that the semi-finished display panel needs to be cut / broken off. The sheet-breaking assembly 20 also has a handle 22. The handle 22 is connected to the sheet-breaking plate 21. The handle 22 is adjacent to the center position of the sheet-breaking plate 21. The handle 22 is, for example, fixedly connected to the top center position of the sheet-breaking plate 21. When the part of the semi-finished display panel that needs to be cut / broken off is placed in the groove 211, according to the position of the bait to be broken off, pressing the first button 31 enables the sheet-breaking plate 21 to execute a counterclockwise sheet-breaking mode, or pressing the second button 32 enables the sheet-breaking plate 22 to execute a clockwise sheet-breaking mode. At this time, the operator can rotate the sheet-breaking plate 21 counterclockwise or clockwise through the handle 22, so as to separate the bait part from the semi-finished display panel.
[0026] The breaking device 100 of the present utility model places the semi-finished display panel to be cut / broken on the stage 10 and protrudes the bait part to be cut. A breaking component 20 with a groove 211 is arranged on the side of the stage 10. By placing the bait part in the groove 211 of the breaking component 20, since the second length L2 of the groove 211 is equal to the first length L1 of the second side 12 and the first width W1 of the groove 211 is greater than or equal to the width that needs to be cut of the semi-finished display panel, the bait part is completely accommodated in the groove 211, improving the uniformity of the external force received by the bait part during the breaking process, avoiding damage to the display panel, and thus improving the production yield.
[0027] In an embodiment, the breaking device 100 further includes a vertical plate 40. The vertical plate 40 is arranged on the base 90. Along the extending direction of the second side 12, the vertical plate 40 is correspondingly arranged outside the breaking plate 21. The vertical plate 40 is rotatably connected to the breaking plate 21 and the control component 30 is located on the vertical plate 40. And in an embodiment, the vertical plate 40 is adjacent to the first side 11 and / or the third side 13 of the stage 10, so that the control component 30 arranged thereon is adjacent to the first side 11 and / or the third side 13 of the stage 10. For example, vertical plates 40 are arranged on both sides of the breaking component 20 (that is, adjacent to the left and right sides of the stage 10), and the control component 30 can be located on at least one of the vertical plates 40. The vertical plate 40 includes a connected first part and a second part. The first part is fixed to the base 90, and the second part is generally in an inverted L shape. The control component 30 is located on the side of the vertical plate 40 (specifically, for example, its second part) close to the stage 10.
[0028] In an embodiment, the breaking device 100 further includes a connecting component 50. The control component 30 is connected to the breaking component 20 through the connecting component 50. The connecting component 50 has a connecting plate 51. The connecting plate 51 is fixedly connected to the breaking plate 21, and the connecting plate 51 is rotatably connected to the vertical plate 40. The connecting plate 51 includes a first connecting plate 511 and a second connecting plate 512. The first connecting plate 511 and the second connecting plate 512 are perpendicularly connected. The first connecting plate 511 is rotatably connected to the vertical plate 40 (specifically, for example, its second part) and is opposite to the side of the breaking plate 21 adjacent to the corresponding vertical plate 40 and the first connecting plate 511 is parallel to the first side 11. The second connecting plate 512 is fixedly connected to the side of the breaking plate 21 opposite to the groove 211 and the second connecting plate 512 is parallel to the second side 12. Thus, the connecting plate 51 drives the breaking plate 21 to be rotatable relative to the vertical plate 40.
[0029] In an embodiment, the connecting component 50 has two connecting plates 51. The two connecting plates 51 correspond to the opposite sides of the breaking plate 21 and are respectively rotatably connected to the corresponding vertical plates 40. As Figure 3As shown, at least one hole 212 is provided in the breaking plate 21 adjacent to the first side 11 and the third side 13 (for example, a through hole penetrating from the side of the breaking plate 21 opposite to the groove 211 to the surface where the groove 211 is located, or a blind hole facing the surface where the groove 211 is located from the side of the breaking plate 21 opposite to the groove 211). The fixing component (not shown in the figure) passes through or is threaded into at least one hole 212 to fixedly connect the connecting plate 51 (specifically, the second connecting plate 512) and the breaking plate 21. For example, a stud passes through a hole 212 on the breaking plate 21 and a corresponding hole on the connecting plate 51 and is fixedly locked with a nut, but this is not limited in actual applications. That is, each connecting plate 51 is fixedly connected to the breaking plate 21 via the corresponding second connecting plate 512, and at the same time, each connecting plate 51 is rotatably connected to the corresponding vertical plate 40 via the corresponding first connecting plate 511. In an embodiment, the first connecting plate 511 of each connecting plate 51 can also be fixedly connected to the breaking plate 21. For example, the first connecting plate 511 is adhered to the side surface of the breaking plate 21 via double-sided tape.
[0030] In an embodiment, as Figure 2 shown, the carrier 10 has opposite first surface 14 and second surface 15. The first surface 14 has a plurality of suction holes 141, and the plurality of suction holes 141 are connected to a vacuum suction system (not shown in the figure, for example, arranged below the carrier 10). The second surface 15 has a plurality of connection holes (not shown in the figure), and the plurality of connection holes are communicated with the plurality of suction holes 141, and a plurality of suction tubes of the vacuum suction system are connected to the corresponding connection holes. When the semi-finished display panel to be cut / broken is placed on the carrier 10, the semi-finished display panel is vacuum-sucked through the plurality of suction holes 141 to keep the position of the semi-finished display panel fixed, so as to avoid the displacement of the semi-finished display panel during the breaking process and affect the breaking result. As Figure 1 shown, the first surface 14 of the carrier 10 has a plurality of limiting plates 142, and the plurality of limiting plates 142 can adapt to the shape of the semi-finished display panel. That is, the shape formed by the plurality of limiting plates 142 matches the shape of the semi-finished display panel, which is convenient for prompting the operator to place the semi-finished display panel on the carrier 10 and can limit the semi-finished display panel. For example, the plurality of limiting plates 142 are a plurality of discontinuous structures arranged along different sides according to the shape of the semi-finished display panel. In an embodiment, the plurality of limiting plates 142 can move on the first surface 14 to change the formed shape to adapt to various semi-finished display panels.
[0031] In one embodiment, the dicing device 100 further includes a support assembly 60. The support assembly 60 is used to support the stage 10 and is disposed on the base 90. The support assembly 60 has a plurality of support portions 61. In the thickness direction of the stage 10, the stage 10 extends from the second surface 15 to form a plurality of extension portions (not shown in the figure). The plurality of extension portions correspond to the plurality of support portions 61 one by one, and the plurality of extension portions and the plurality of support portions 61 are correspondingly connected through a plurality of fixing components 70. One side of the plurality of fixing components 70 connected to the plurality of extension portions has a chute (not shown in the figure) extending in the thickness direction of the stage 10. The end of each extension portion may be provided with a sliding member (not shown in the figure), and the sliding member is slidably disposed in the corresponding chute. In this way, the height of the stage 10 can be adjusted by sliding the sliding member in the chute. In this embodiment, the support assembly 60 has four support portions 61, corresponding to the four corners of the stage 10 respectively. By adjusting the height of the four corners of the stage 10 through each sliding member, the entire stage 10 is in the same plane.
[0032] In one embodiment, the dicing device 100 further includes an adjustment assembly 80. The adjustment assembly 80 is used to adjust the height of the stage 10. The adjustment assembly 80 has a plurality of adjustment portions, and the plurality of adjustment portions are respectively adjacent to the central positions of the first side 11 and the third side 13 of the stage 10. In this embodiment, the adjustment assembly 80 has two adjustment portions, which are respectively adjacent to the central positions of the first side 11 and the third side 13 of the stage 10. The height of the stage 10 can be adjusted so that when the semi-finished display panel is placed on the stage 10, the height of the bait portion to be cut of the semi-finished display panel is flush with the height of the groove 211 of the dicing plate 21. In one embodiment, each adjustment portion may include a micrometer knob. In practical applications, when an operator places the semi-finished display panel to be cut on the stage 10, the height of the stage 10 can be first adjusted through the adjustment assembly 80 so that the semi-finished display panel is aligned with the position where the groove 211 is located. Then, the position of the sliding member in the fixing component 70 can be adjusted to adjust the relative position relationship between each support portion 61 of the support assembly 60 and each extension portion of the stage 10. So that when the height of the stage 10 is fixed, the height of the four corners of the stage 10 can be further finely adjusted to assist in improving the height uniformity of the stage 10, and the stage 10 is stably supported by the support assembly 60 at the four corners.
[0033] Please refer to Figure 4 , Figure 4 , which shows a schematic structural diagram of the control component of the dicing device of the present utility model. As Figure 3 and Figure 4As shown, in this embodiment, the first button 31 has a first pressing portion and a first protruding portion 311 connected thereto and extending toward the corresponding connecting plate 51. The second button 32 has a second pressing portion and a second protruding portion 321 connected thereto and extending toward the corresponding connecting plate 51. In one embodiment, the first button 31 and the second button 32 are disposed on the same vertical plate 40. The first connecting plate 511 has a recessed portion (not shown in the figure) and a limiting post 5111 corresponding to the first protruding portion 311 and the second protruding portion 312 respectively. The shape and size of each recessed portion match those of the first protruding portion 311 and the second protruding portion 312. Each limiting post 5111 is disposed at the bottom of each recessed portion, and when the breaking piece plate 21 is in the horizontal position, the connecting line of each limiting post 5111 is horizontal or nearly horizontal. In this embodiment, the first protruding portion 311 and the second protruding portion 312 are cylindrical and have a notch along the axis of the cylinder. Further, this notch can be a notch formed along the radius direction of the cylinder from the central axis of the cylinder, and each notch can have an opposite first inner wall and a second inner wall. When, according to the position of the bait to be broken off on the semi-finished display panel, the first pressing portion of the first button 31 is selected to be pressed, the first protruding portion 311 is inserted into the corresponding recessed portion, and the corresponding limiting post 5111 is adjacent to or close to the first inner wall of the notch of the first protruding portion 311. At this time, the user can only rotate the breaking piece plate 21 counterclockwise, thereby realizing the breaking piece operation of the bait portion. When, according to the position of the bait to be broken off on the semi-finished display panel, the second pressing portion of the second button 32 is selected to be pressed, the second protruding portion 312 is inserted into the corresponding recessed portion, and the corresponding limiting post 5111 is adjacent to or close to the second inner wall of the notch of the second protruding portion 312. At this time, the user can only rotate the breaking piece plate 21 clockwise, thereby realizing the breaking piece operation of the bait portion. In one embodiment, the notch angle of the first protruding portion 311 and the second protruding portion 312 is the maximum angle at which the breaking piece plate 21 can rotate. When cooperating with the limiting post 5111, the user can rotate within this angle range for breaking the piece, and the size of this angle can be set according to actual needs.
[0034] In practical applications, the operator first places the semi-finished display panel to be cut on the stage 10 and protrudes the bait part to be cut. There is no gap between the splitting component 20 and the second side 12 of the stage 10. That is, when the semi-finished display panel is placed on the stage 10, the part that does not need to be cut is located on the stage 10, and the bait part to be cut is located in the groove 211 of the splitting plate 21. The cutting line corresponds to the connection line between the splitting component 20 and the second side 12. According to the type of the semi-finished display panel, the operator determines whether to use the upward splitting or downward splitting method. If the upward splitting method is selected, the operator presses the first button 31, and the first protrusion 311 is embedded in the recess of the first connecting plate 511 and can only rotate counterclockwise under the restriction of the limit post 5111. At this time, the operator holds the handle 22 and rotates counterclockwise to drive the splitting plate 21 to rotate synchronously. The bait part to be cut is separated from the semi-finished display panel under the external force brought by the rotation of the splitting plate 21, thus realizing the splitting of the semi-finished display panel.
[0035] In summary, the present invention provides a splitting device. By placing the semi-finished display panel to be cut on the stage and protruding the bait part to be cut, a splitting component with a groove is arranged on the side of the stage, and the bait part is placed in the groove of the splitting component. The splitting component is controlled by a control component to rotate to separate the bait part from the semi-finished display panel. Even if the width of the bait part to be cut is narrow, since it is completely accommodated in the groove of the splitting component, the force received during the splitting process is more uniform, and no bad conditions such as glass debris or cracks will occur, thereby improving the production yield.
[0036] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
