[0027] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0028] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] See also Figures 1 to 6 , which is a screen disassembly device of an embodiment of the present invention, includes an adsorption component 10, a clamping component 20 located above the adsorption component 10, and a calibration plate 30 detachably connected to the adsorption component 10; the calibration plate 30 is used to calibrate the relative position of the adsorption component 10 and the clamping component 20 to ensure positioning accuracy.

[0031] The adsorption assembly 10 includes a base 11, thermal pads 12 mounted on opposite sides of the top surface of the base 11, heating tubes 13 mounted within each thermal pad 12, rubber-coated suction cups 14 mounted on the top of each thermal pad 12, and air nozzles 15 mounted on the bottom of each thermal pad 12. The top of the air nozzles 15 connects upwardly to the rubber-coated suction cups 14, and the bottom of the air nozzles 15 connects externally to a vacuum pump via a hose. The rubber-coated suction cups 14 are used to adhere to the phone's screen.

[0032] Specifically, if Figure 4 As shown, the heat conducting base 12 has an exhaust groove 120 in the middle along its thickness direction, and the exhaust groove 120 corresponds to the air nozzle 15. The rubber-coated suction cup 14 has an exhaust hole 140 in the middle along its thickness direction, and the exhaust hole 140 corresponds to the exhaust groove 120.

[0033] The clamping assembly 20 includes two hinged cover plates 21, a long-side fixed clamping block 22 mounted on the inner long side of the bottom surface of each cover plate 21, a long-side movable clamping block 23 movably mounted on the outer long side of the bottom surface of each cover plate 21, a short-side movable clamping block 24 movably mounted on the short sides of the bottom surface of each cover plate 21, and a driving cylinder 25 mounted on the top surface of each cover plate 21. The area enclosed by the long-side fixed clamping block 22, the long-side movable clamping block 23, and the two short-side movable clamping blocks 24 forms a clamping cavity, which is used to position and clamp the mobile phone body. The driving cylinder 25 is used to simultaneously drive the long-side movable clamping block 23 and the short-side movable clamping block 24 toward the center of the cover plate 21 to shrink the size of the clamping cavity, thereby clamping the mobile phone body and effectively improving positioning accuracy.

[0034] like Figure 3 As shown, a positioning hole 210 is provided on the bottom surface of the cover plate 21 corresponding to the inside of the clamping cavity. The positioning hole 210 corresponds one-to-one with the exhaust hole 140, which can facilitate the positioning of the calibration plate 30.

[0035] like Figure 5 and Figure 6As shown, the long side movable clamping block 23 is upwardly connected to a first sliding block 230 , and the short side movable clamping block 24 is upwardly connected to a second sliding block 240 .

[0036] The top surface of the cover plate 21 is provided with a first slot 211 and two second slots 212. The first slot 211 is configured to accommodate the first slider 230, while the second slots 212 are configured to accommodate the second slider 240. The first slider 230 is connected to the drive cylinder 25, which is connected to the second slider 240 via a linkage mechanism. This allows the drive cylinder 25 to control the long-side movable clamp 23 and the two short-side movable clamps 24 to work in unison.

[0037] Specifically, the linkage mechanism includes a V-shaped link 261 hinged to the top surface of the cover plate 21, a first drive rod 262 hinged to one end of the V-shaped link 261, and a second drive rod 263 hinged to the other end of the V-shaped link 261. The end of the first drive rod 262, away from the V-shaped link 261, is hinged to the first slider 230, and the end of the second drive rod 263, away from the V-shaped link 261, is hinged to the second slider 240. The opening of the V-shaped link 261 faces the first slider 230. When the drive cylinder 25 pushes the first slider 230 to slide, the second slider 240 slides with it.

[0038] In this embodiment, the clamping assembly 20 also includes a solenoid valve 27 connected to each driving cylinder 25, and a baffle 28 connected to the top surface of each cover plate 21; the baffle 28 is used to cover the first slider 230, the second slider 240 and the connecting rod mechanism.

[0039] Furthermore, the entire clamping assembly 20 is also used to connect to an external force structure such as a handle or a robot arm, which can move the entire clamping assembly 20 upward.

[0040] The calibration plate 30 includes two base plates 31 and positioning pins 32 mounted on opposite sides of the base plates 31. The base plates 31 are used to attach the rubber-coated suction cups 14. The positioning pins 32 on the bottom surface of the base plates 31 correspond to the air extraction holes 140, while the positioning pins 32 on the top surface of the base plates 31 correspond to the positioning holes 210. This calibrates the relative position of the suction assembly 10 and the clamping assembly 20 to ensure positioning accuracy.

[0041] After calibration is completed, the clamping assembly 20 rises and the calibration plate 30 is removed to prepare for placing the mobile phone. Then put the mobile phone in, with the mobile phone screen facing the rubber-coated suction cup 14, and the clamping assembly 20 descends and tightens the clamping cavity, automatically completing the precise positioning and clamping of the mobile phone in this process. The vacuum pump is then started, and negative pressure is generated through the rubber-coated suction cup 14 to tightly adsorb the mobile phone screen to ensure that the mobile phone will not slip or move during the separation process. The heating tube 13 starts to work and continues to heat up for a certain period of time. The heat generated by the heating tube 13 is transferred to the mobile phone screen through the thermal seat 12 and the rubber-coated suction cup 14, heating the glue on the back of the mobile phone screen, softening it, and reducing the difficulty of separation. After the glue softens, the clamping assembly 20 rises again. Since the mobile phone screen is firmly adsorbed by the rubber-coated suction cup 14, the mobile phone body follows the clamping assembly 20 to move up, thereby realizing the separation of the mobile phone body and the mobile phone screen.

[0042] In actual use, the two cover plates 21 can be divided into a fixed cover plate 21 and a movable cover plate 21. When the separation starts, the movable cover plate 21 is first lifted up to a certain angle, which is equivalent to breaking the connection between the mobile phone body and the mobile phone screen from one side of the mobile phone, effectively reducing the tension between the mobile phone body and the mobile phone screen, reducing the risk of screen damage, and improving the success rate and efficiency of separation.

[0043] The above-mentioned screen disassembly device has a simple structure and is easy to use. The rubber-coated suction cup 14 adsorbs the mobile phone screen, and the heating tube 13 heats the adhesive on the back of the mobile phone screen to soften it. The clamping component 20 is used to move the mobile phone body upward, which can quickly separate the mobile phone screen and the mobile phone body, greatly improving the separation efficiency and effectively reducing the maintenance cost and time.

[0044] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
