[0003] In the existing technology, pre-cut LCDs are separated into individual units manually. However, manual separation is inefficient and cannot meet production needs. Furthermore, the human body carries static electricity, and even with anti-static equipment, there are still situations where the anti-static equipment fails or is not worn correctly, which can lead to damage to the LCDs.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Example 1 Please see Figures 1 to 3The automatic LCD panel separation device in Embodiment 1 of the present invention includes a primary separation unit 1 and a secondary separation unit 3. The primary separation unit 1 includes a plurality of parallel and spaced slide rails 10. Each slide rail 10 includes an adsorption section 12 and a transfer section 14 at both ends. A sliding segment 13 for breaking the LCD is provided between the adsorption section 12 and the transfer section 14. A plurality of sliding components 20 are slidably disposed on the slide rails 10. Each sliding component 20 includes a first sliding structure 21 correspondingly slidably disposed on the slide rail 10. A hanging rail 22 is provided at the bottom of the corresponding first sliding structure 21. The upper part has several second sliding structures 23, and at the bottom of the second sliding structure 23 is an adsorption structure 24 for adsorbing the LCD. The secondary particle-splitting unit 3 is located on one side of the transfer section 14. The secondary particle-splitting unit 3 includes several parallel and spaced guide rails 30 for transferring the second sliding structure 23. The guide rails 30 are arranged corresponding to the sliding component 20. The guide rails 30 include a bearing section 31 and an unloading section 33 at both ends. A particle-splitting section 32 for breaking the LCD is arranged between the bearing section 31 and the unloading section 33. The bearing section 31 is arranged facing the side of the transfer section 14.

[0021] Understandably, the number of slide rails 10, sliding components 20, and the second sliding structure 23 can be flexibly adjusted according to the number of pre-cut LCD panels required, so that the present invention can be applied to LCD panels with different numbers of panels and improve production efficiency.

[0022] Furthermore, the slit segment 13 and the granular segment 32 are several arc-shaped structures.

[0023] Understandably, by setting the sliding segment 13 and the granulation segment 32, and by making the sliding segment 13 and the granulation segment 32 into several arc-shaped structures, when the leading sliding component 20 passes through the sliding segment 13, the adjacent sliding component 20 is still located in the adsorption segment 12. The leading sliding component 20 and the adjacent sliding component 20 will form an angle, causing the pre-cut LCD adsorbed at the bottom of the leading sliding component 20 and the pre-cut LCD at the bottom of the adjacent sliding component 20 to be separated by relative stress. Similarly, when the leading second sliding structure 23 passes through the granulation segment 32, the adjacent second sliding structure 23 is still located in the bearing segment 31. The leading second sliding structure 23 and the adjacent second sliding structure 23 will form an angle, causing the pre-cut LCD adsorbed at the bottom of the leading second sliding structure 23 and the pre-cut LCD at the bottom of the adjacent second sliding structure 23 to be separated by relative stress. This avoids a series of problems caused by manual granulation.

[0024] It should be noted that when the sliding component 20 slides to the transfer section 14, the upper surface of the bearing section 31 is at the same height as the upper surface of the hanging rail 22, the interval between two adjacent hanging rails 22 is equal to the interval between two adjacent guide rails 30, and the gap between the bearing section 31 and the transfer section 14 is less than the length of the second sliding structure 23.

[0025] Understandably, when the sliding component 20 slides to the transfer section 14, the upper surface of the bearing section 31 is at the same height as the upper surface of the hanging rail 22, and the interval between two adjacent hanging rails 22 is equal to the interval between two adjacent guide rails 30. Furthermore, the gap between the bearing section 31 and the transfer section 14 is less than the length of the second sliding structure 23. This allows the pre-cut LCD located in the transfer section 14 after completing the first-stage grain-splitting unit 1 process to slide from the hanging rail 22 to the bearing section 31 via the second sliding structure 23, thereby enabling the second-stage grain-splitting unit 3 process to proceed.

[0026] Furthermore, a lifting structure 40 for placing and raising / lowering the LCD is provided below the adsorption section 12.

[0027] Understandably, by providing a lifting structure 40 for placing and raising / lowering the LCD below the adsorption section 12, the LCD can be more easily adsorbed by the adsorption structure 24.

[0028] Furthermore, a proximity switch 11 is provided on the web of the slide rail 10. The proximity switch 11 is located at the end of the transfer section 14 away from the sliding section 13, and when the proximity switch is triggered, the hanging rail 22 aligns with the guide rail 30.

[0029] Understandably, by providing a proximity switch 11 on the web of the slide rail 10, the second sliding structure 23 can slide more conveniently from the hanging rail 22 to the bearing section 31 after the sliding assembly 20 completes the first-stage granulation unit 1 process.

[0030] Furthermore, a storage structure 50 is provided below the unloading section 33.

[0031] Understandably, by providing a storage structure 50 below the unloading section 33, the LCD after the granulation process can be stored in the storage structure 50.

[0032] Furthermore, a first support leg 19 is connected to one end of the slide rail 10 near the transfer section 14, a second support leg 39 is connected to one end of the guide rail 30 near the unloading section 33, a top plate 60 is provided on the top of the adsorption section 12 and the bearing section 31, and support legs 61 are connected to the bottom of the four corners of the top plate 60.

[0033] Example 2 Please see Figure 4 Embodiment 2 of the present invention provides a particle-splitting method for an automatic particle-splitting device for LCD panels, the particle-splitting method comprising the following steps: S1. Provide a pre-cut LCD panel; In this embodiment of the invention, the pre-cut LCD panel comprises 3*3 individual pieces.

[0034] S2. The pre-cut LCD panel is adsorbed onto the primary particle sizing unit 1; In one embodiment of the invention, the pre-cut LCD panel is placed on the lifting structure 40, and the relative position of the pre-cut LCD panel and the adsorption structure 24 is adjusted to control the lifting structure 40 to rise, so that the pre-cut LCD panel is adsorbed by the adsorption structure 24. The primary particle-splitting unit 1 includes two parallel and spaced slide rails 10. Each slide rail 10 includes an adsorption section 12 and a transfer section 14 at both ends. A sliding section 13 for breaking the LCD is provided between the adsorption section 12 and the transfer section 14. Three sliding components 20 are slidably disposed on the slide rail 10. Each sliding component 20 includes a first sliding structure 21 slidably disposed on the slide rail 10. A hanging rail 22 is disposed at the bottom of the corresponding first sliding structure 21. Three second sliding structures 23 are slidably disposed on the hanging rail 22. An adsorption structure 24 for adsorbing an LCD is disposed at the bottom of the second sliding structure 23. The segmented sections are composed of several arc-shaped structures; It should be noted that in this embodiment of the invention, the first sliding structure 21 and the second sliding structure 23 are electric sliders, and the adsorption structure 24 is a vacuum suction cup.

[0035] S3. The pre-cut LCD panel is divided into several strips according to the arrangement of the sliding assembly 10 by the primary granulation unit 1. In this embodiment of the invention, when the sliding component 20 passes through the segment 13, the adjacent sliding component 20 is still located in the adsorption segment 12. The leading sliding component 20 and the adjacent sliding component 20 will form an angle, so that the pre-cut LCD adsorbed at the bottom of the leading sliding component 20 and the pre-cut LCD at the bottom of the adjacent sliding component 20 are subjected to relative stress and separated, so that the pre-cut LCD board is divided into three strips.

[0036] S4. Move the LCD panels, which are arranged and divided into several strips, to the secondary particle division unit 3; In this embodiment of the invention, the LCD panel divided into three sections is moved toward the transfer section 14 by the first sliding structure 21 until it touches the proximity switch 11, and then the LCD panel divided into three sections is slid from the hanging rail 22 to the bearing section 31 by the second sliding structure 23. It should be noted that when the sliding component 20 slides to the transfer section 14, the upper surface of the bearing section 31 is at the same height as the upper surface of the hanging rail 22, the interval between two adjacent hanging rails 22 is equal to the interval between two adjacent guide rails 30, and the gap between the bearing section 31 and the transfer section 14 is less than the length of the second sliding structure 23. It should be noted that a proximity switch 11 is provided on the web of the slide rail 10. The proximity switch 11 is located at the end of the transfer section 14 away from the sliding section 13, and when the proximity switch 11 is triggered, the hanging rail 22 aligns with the guide rail 30.

[0037] S5. The LCD panel, which is arranged into several strips, is divided into several units according to the arrangement of the second sliding structure through the secondary granulation unit. In this embodiment of the invention, when the second sliding structure 23 passes through the particle segment 32, the adjacent second sliding structure 23 is also located in the bearing segment 31. The leading second sliding structure 23 and the adjacent second sliding structure 23 will form an angle, so that the pre-cut LCD adsorbed on the bottom of the leading second sliding structure 23 and the pre-cut LCD on the bottom of the adjacent second sliding structure 23 are subjected to relative stress and separated, so that the pre-cut LCD board divided into three strips is divided into nine pieces. The secondary particle division unit 3 is located on one side of the transfer section 14; The secondary particle-splitting unit 3 includes three parallel and spaced guide rails 30 for transferring the second sliding structure 23. Each guide rail 30 includes a bearing section 31 and an unloading section 33 at both ends. A particle-splitting section 32 for breaking the LCD is provided between the bearing section 31 and the unloading section 33. The bearing section 31 is disposed on the side facing the transfer section 14; The aforementioned particle segment 32 consists of several arc-shaped structures.

[0038] S6. Collect the LCD panels after particle separation; In this embodiment of the invention, the LCD panel that has undergone secondary granulation through the granulation segment 32 is moved above the storage structure 50 via the second sliding structure 23, and the adsorption structure 24 is released so that the granulated LCD panel falls into the storage structure 50.

[0039] In summary, the automatic LCD panel splitting device and method in the above embodiments of the present invention, by setting a plurality of parallel and spaced slide rails, by sliding a plurality of sliding components on the slide rails, by setting a hanging rail at the bottom of the corresponding first sliding structure, and by sliding a plurality of second sliding structures on the hanging rails, can flexibly adjust the number of slide rails, sliding components, and second sliding structures according to the required number of pre-cut LCD panels, so that the present invention can be applied to LCD panels with different splitting numbers, thereby improving production efficiency; by setting slitting segments and splitting segments, the slitting segments and splitting segments are several arc-shaped structures. This design causes the leading sliding component to tilt as it passes through the segmented section of the arc-shaped structure, creating an angle with its adjacent sliding components. Consequently, the pre-cut LCDs adsorbed at the bottom of the leading sliding component are separated from the pre-cut LCDs at the bottom of its adjacent sliding components. Similarly, the leading second sliding structure tilts as it passes through the segmented section of the arc-shaped structure, creating an angle with its adjacent second sliding structure. This further separates the pre-cut LCDs adsorbed at the bottom of the leading second sliding structure from the pre-cut LCDs at the bottom of its adjacent second sliding structure, thus avoiding a series of problems associated with manual segmentation.
