Please refer to Figure 2. FIG. 2 is a flowchart of a method 500 for disassembling the display screen 210 and the cover 220 (see FIG. 1 for the display 210 and the cover 220) according to an embodiment of the present invention. In this embodiment, as shown in Fig. 2, the disassembly method 500 includes the following steps (it should be understood that the steps mentioned in some embodiments, except for those whose order is specifically stated, can be based on actual needs. Adjust its sequence, even at the same time or partly at the same time):

(1) Place the display device 200 in the work space SW (step 510). Please refer to Figure 3. Fig. 3 is a partial enlarged view showing the range M of Fig. 1. In this embodiment, as shown in FIG. 3, the display device 200 includes a display screen 210 and a cover 220, and the display 210 and the cover 220 are connected by optical glue 230. The display device 200 is actually a part to be disassembled, that is, the user wants to disassemble the cover 220 from the display screen 210 through the disassembly method 500.

(2) Fix the display screen 210 on the fixing element 120 (step 520). More specifically, as shown in FIGS. 1 and 3, the user fixes the display screen 210 of the display device 200 on the fixing surface 121 of the fixing element 120.

(3) Inject the cooling liquid LC into the working space SW to embrittle the optical glue 230 (step 530). Please refer to Figure 4. Fig. 4 is a schematic cross-sectional view of the dismantling device 100 of Fig. 1, in which a cooling liquid LC is injected into the working space SW. After the user fixes the display screen 210 of the display device 200 on the fixing surface 121 of the fixing element 120, the user supplies the cooling liquid LC to the working space SW through the cooling liquid supply 140. Due to the low temperature of the cooling liquid LC, the optical glue 230 connected between the display screen 210 and the cover 220 becomes brittle.

(4) Repetitively hit at least one side of the cover 220 to damage the optical glue 230 (see Figure 3 for the optical glue 230), thereby separating the cover 220 from the display screen 210 (step 540). Please refer to Figure 5. FIG. 5 is a schematic cross-sectional view of the disassembling device 100 of FIG. 1, in which the impact element 130 collides with the cover 220. In this embodiment, when the optical glue 230 is first made brittle, and then repeatedly collide with at least one side of the cover plate 220 in the moving direction DM parallel to the fixed surface 121, the optical glue 230 can be effectively damaged without It may cause damage to the cover 220 or the display screen 210. Moreover, as described above, the impact element 130 is made of a soft material. Therefore, when the impact element 130 collides with the cover plate 220, the impact element 130 will be elastically deformed, thereby avoiding damage to the cover plate 220 due to the impact of the impact element 130. When the optical glue 230 is destroyed, the cover 220 is disassembled and separated from the display screen 210. In practical applications, for example, the frequency of the repeated collision cover 220 is about 5 Hz to about 15 Hz, but the present invention is not limited thereto.

Please refer to Figure 6. FIG. 6 is a cross-sectional view taken along the line A-A in FIG. 5, in which the impact element 130 includes a plane SF. In this embodiment, as shown in Figure 6, the plane SF of the impact element 130 faces the fixing element 120 (please refer to Figures 1, 3, 4, and 5), that is, towards the display device 200 fixed on the fixing element 120 . When the side of the cover 220 of the display device 200 facing the impact element 130 is a straight edge, the force of the impact element 130 hitting the cover 220 with the flat SF can be more evenly distributed on the cover 220. However, for example, when the side of the cover 220 of the display device 200 facing the impact element 130 is curved, the user can still use the impact element 130 including the flat SF to impact the cover 220.

Please refer to Figure 7. FIG. 7 is a cross-sectional view along the line A-A in FIG. 1, in which the impact element 130 includes a concave surface SC. In this embodiment, as shown in Fig. 7, the concave surface SC of the striking element 130 faces the fixing element 120 (please refer to Figs. 1, 3, 4, and 5), that is, towards the display device 200 fixed on the fixing element 120 . When the side of the cover 220 of the display device 200 facing the impact element 130 is an arc, the force of the impact element 130 hitting the cover 220 with the concave surface SC can be more evenly distributed on the cover 220. However, for example, when the side of the cover 220 of the display device 200 facing the impact element 130 is straight, the user can still use the impact element 130 including the concave surface SC to impact the cover 220.

In addition, as described above, the fixing element 120 is located between at least two adjacent impact elements 130, that is, the display device 200 is located between at least two adjacent impact elements 130. Therefore, the step 540 of repeatedly hitting the cover 220 further includes:

(4.1) Alternately collide the opposite sides of the cover 220 (step 541) to improve the efficiency of destroying the optical glue 230, and thereby improve the operating efficiency of the dismantling device 100.

Furthermore, as described above, the number of fixing elements 120 is plural, that is, plural display devices 200 can be accommodated in the working space SW of the housing 110. Therefore, the step 540 of repeatedly hitting the cover 220 further includes:

(4.2) Alternately collide with the corresponding sides of the two adjacent cover plates 220 facing each other (step 542), so as to improve the operating efficiency of the driving device 160 and the dismantling equipment 100.

In this embodiment, as shown in Figure 2, the disassembly method 500 further includes:

(5) The cover 220 that is disassembled and separated from the display 210 is placed in the accommodating space SA (step 550). Please refer to Figure 8. FIG. 8 is a schematic cross-sectional view showing the disassembly device 100 of FIG. 1, in which the cover 220 falls into the accommodating space SA. Specifically, when the optical glue 230 is destroyed and the cover 220 is disassembled and separated from the display 210, the cover 220 will fall from the working space SW into the accommodating space SA through the perforation HT of the structural plate 111, such as As shown in Figure 8, the user is allowed to carry out subsequent storage in the accommodation space SA.

In summary, the technical solutions disclosed in the foregoing embodiments of the present invention have at least the following advantages:

(1) When the optical glue becomes brittle first, and then repeatedly collide with at least one side of the cover plate in the direction of movement parallel to the fixed surface, the optical glue can be effectively destroyed without causing damage to the cover plate or the display screen. damage.

(2) Since the impact element is made of soft material, when the impact element collides with the cover plate, the impact element will be elastically deformed, so that damage to the cover plate due to the impact of the impact element can be avoided.

(3) Since the impact element can alternately impact the opposite sides of the cover plate, the efficiency of destroying the optical glue can be improved, and the operating efficiency of the dismantling equipment can be improved.

(4) Since the impact element can alternately impact the corresponding sides of the two adjacent cover plates facing each other, the operating efficiency of the driving device and the dismantling equipment can be improved.
