[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

In addition, in the drawings, in order to effectively describe the technical content, the thickness of the components may be exaggerated or reduced.

[0026] Herein, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." modify the entire list of elements when following a list of elements, rather than modifying individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0027] The terms used herein are only used to describe specific exemplary configurations and are not intended to be limited. As used herein, the singular articles "one", "an" and "the" may also be intended to include plural forms, unless it is clearly indicated above that this is not the case.

[0029] Research has found that the disadvantages of the prior art are that a protective film needs to be attached to the surface of the glass substrates during stacking to prevent scratches and contamination, and the protective film needs to be removed during processing.

[0030] In the related art, the protective film on the surface of the glass substrate is mostly disposable. Before the sheet-taking device takes a single glass substrate from the stacking table under negative pressure, the protective film on the surface of the glass substrate needs to be torn off. This loading method increases the operation time of taking out the glass substrate, and at the same time, the torn protective film cannot be reused.

[0031] Therefore, how to solve the problem that the protective film takes too long to be removed and cannot be used a second time is a technical problem that needs to be solved urgently in the art.

[0032] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0034] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] like Figures 1 to 6As shown, at least one embodiment provides a glass substrate fetching device, comprising: a placement table 1, glass substrates 4 are stacked on the upper end of the placement table 1; when the glass substrates 4 are stacked, a protective film 3 is placed on the upper end of each of the glass substrates 4. A fetching device 2 is arranged on one side of the placement table 1, and is suitable for negative pressure adsorption of the glass substrates 4, and the fetching device 2 comprises a plurality of adsorption plates 20; after the fetching device 2 drives the adsorption plates 20 to move above the glass substrates 4, the adsorption plates 20 are inserted into the positioning grooves 30 until the adsorption plates 20 abut against the glass substrates 4, and the fetching device 2 is suitable for transporting the glass substrates 4 on the placement table 1 to the conveyor belt, and in the process of separating the glass substrates 4 from the adsorption plates 20, the protective film 3 on the surface of the glass substrates 4 is separated from the glass substrates 4.

[0036] Reference Figure 4 , a protective film 3 is attached to the surface of the glass substrate 4; a plurality of positioning grooves 30 are opened on the protective film 3, and the groove width of the positioning groove 30 is smaller than the outer diameter of the adsorption plate 20; wherein, after the adsorption plate 20 moves to above the positioning groove 30, the adsorption plate 20 flips and shrinks to be inserted into the positioning groove 30; the adsorption plate 20 changes from a contracted state to an extended state in the positioning groove 30, and adsorbs the glass substrate 4 with negative pressure; the film taking device 2 drives the glass substrate 4 to move to the conveyor belt, and the film taking device 2 moves upward relative to the glass substrate 4 to separate the protective film 3 from the glass substrate 4. Through the cooperation of the adsorption disk 20, the protective film 3 and the glass substrate 4, the glass substrate 4 is quickly separated from the protective film 3. The adsorption disk 20 changes from a contracted state to an extended state in the positioning groove 30, and adsorbs the glass substrate 4 with negative pressure. After the glass substrate 4 is separated from the protective film 3, the adsorption disk 20 changes from an extended state to a contracted state, and the blowing structure 25 blows air outward to make the protective film 3 detach from the sheet-taking device 2, which not only improves the work efficiency, but also enables the protective film 3 to be reused multiple times.

A blowing structure 25, one blowing structure 25 corresponds to one adsorption disk 20; the blowing mechanism is connected to the air pump, and the air pump delivers compressed air to the blowing mechanism, so as to facilitate the separation of the protective film 3 located above the adsorption disk 20 from the adsorption disk 20. Among them, after the glass substrate 4 is separated from the protective film 3, at this time, the protective film 3 temporarily stays between the adsorption disk 20 and the support frame 24, at this time, each adsorption disk 20 is suitable for limiting the protective film 3, so as to facilitate the separation of the protective film 3 from the glass substrate 4. When the glass substrate 4 is separated from the protective film 3, the adsorption disk 20 flips and shrinks, and the blowing structure 25 blows air outward to separate the protective film 3 from the adsorption disk 20, so as to facilitate the secondary recycling of the protective film 3.

When the adsorption member 203 is in an unfolded state, the adsorption member 203 abuts against the glass substrate 4, and the negative pressure air pump is suitable for negative pressure adsorption of the glass substrate 4 through the negative pressure holes. The manipulator 23 drives the support frame 24 to move, so as to transport the glass substrate 4 from the placement table 1 to the conveyor belt. The driver 201 is suitable for driving the two adsorption members 203 to contract and deform toward each other or to stretch and deform away from each other.

[0040] Reference Figure 3 , the size of the protective film 3 is larger than that of the glass substrate 4; after the protective film 3 abuts against the upper surface of the glass substrate 4, the edge of the protective film 3 is bent toward the side wall of the glass substrate 4 to protect the surrounding side walls of the glass substrate 4. After the four edges of the protective film 3 are bent downward, a cover with an opening downward is formed to protect the upper surface and surrounding side walls of the glass substrate 4 in the protective film 3.

Further, the fixing strip 31 is an adhesive tape, one end of the fixing strip 31 is fixed to the bent folded portion of the edge of the protective film 3, and the other end extends toward the positioning groove 30 and crosses the positioning groove 30.

[0042] Continue to refer to the attached Figure 4 A tear mark 32 is preset on the fixing strip 31 , and the tear mark 32 is located above the positioning groove 30 .

[0043] Reference Figure 5 In the process of the two adsorption members 203 being relatively contracted and deformed downward to be inserted into the positioning groove 30, the adsorption plate 20 squeezes the fixing strip 31 so that the fixing strip 31 breaks at the tear mark 32.
