[0075] It has been found through research that the disadvantages of the prior art are as follows: During the process of stacking glass substrates, it is necessary to attach a protective film to the surface to prevent surface scratches and contamination. During processing, the protective film on the surface needs to be removed.

[0076] In the related art, the protective film on the surface of the glass substrate is mostly disposable. Before the pick-up device picks up 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. Such a loading method increases the operation time for picking up the glass substrate. At the same time, the torn-off protective film cannot be reused.

[0077] Therefore, how to solve the problem that the removal of the protective film takes too much time and cannot be reused is a technical problem that urgently needs to be solved in the art.

[0078] Regarding the defects existing in the above solutions, they are all the results obtained by the inventors through practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by the present disclosure in this article for the above problems should both be the contributions made by the inventors to the present disclosure during the process of the present disclosure.

[0079] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0080] The following will, with reference to the drawings, elaborate on some embodiments of the present invention. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0081] As Figures 1 to 6 shown, at least one embodiment provides a glass substrate picking device, including: a placing table 1, on which glass substrates 4 are stacked at the upper end; 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 picking device 2, which is arranged on one side of the placing table 1 and is adapted to suck the glass substrate 4 by negative pressure. The picking device 2 includes a plurality of suction cups 20; after the picking device 2 drives the suction cups 20 to move above the glass substrate 4, the suction cups 20 are inserted into the positioning grooves 30 until the suction cups 20 are in contact with the glass substrate 4. The picking device 2 is adapted to transport the glass substrate 4 on the placing table 1 to the conveyor belt. During the process of separating the glass substrate 4 from the suction cups 20, the protective film 3 on the surface of the glass substrate 4 is separated from the glass substrate 4.

[0082] Referring to the attached Figure 4 , the protective film 3 is attached to the surface of the glass substrate 4; a plurality of positioning grooves 30 are formed on the protective film 3, and the slot width of the positioning grooves 30 is smaller than the outer diameter of the suction cups 20; wherein, after the suction cups 20 move above the positioning grooves 30, the suction cups 20 are turned over and contract and deform to be inserted into the positioning grooves 30; the suction cups 20 change from the contracted state to the extended state in the positioning grooves 30 to suck the glass substrate 4 by negative pressure; the picking device 2 drives the glass substrate 4 to move to the conveyor belt, and the picking 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 suction cups 20, the protective film 3 and the glass substrate 4, the separation of the glass substrate 4 from the protective film 3 is realized quickly. The suction cups 20 change from the contracted state to the extended state in the positioning grooves 30 to suck the glass substrate 4 by negative pressure. After the glass substrate 4 is separated from the protective film 3, the suction cups 20 change from the extended state to the contracted state, and the blowing structure 25 blows air outwards so that the protective film 3 detaches from the picking device 2, which not only improves the working efficiency but also enables the protective film 3 to be reused multiple times.

[0083] Referring to the attached Figure 1The film-taking device 2 includes: a base 21, which is arranged between the placement table 1 and the conveyor belt; the base 21 is arranged horizontally; a support base 22, which is slidably arranged on the base 21; a manipulator 23, which is arranged at the upper end of the support base 22; the manipulator 23 is suitable for driving the support frame 24 to move at any angle up, down, left, and right.

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.

[0085] Continue to refer to the attached Figure 2 The adsorption plate 20 includes: a driver 201, which is arranged on the side wall of the support frame 24; a positioning block 202, which is arranged below the support frame 24; two adsorption members 203, which are symmetrically hinged at the lower end of the positioning block 202, and the two adsorption members 203 are connected to the driver 201 in a transmission manner; each of the adsorption members 203 is provided with a plurality of negative pressure holes, which are connected to the negative pressure air pump. 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.

[0086] 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.

[0087] Reference Figure 4, in order to improve the relative stability between the bent portion at the edge of the protective film 3 and the upper surface portion of the protective film 3, a fixing strip 31 is provided at the bent portion of the protective film 3. The fixing strip 31 is fixed on the upper surface of the protective film 3 and extends towards the positioning groove 30. Further, the fixing strip 31 is a tape. One end of the fixing strip 31 is fixed at the bent and folded portion of the edge of the protective film 3, and the other end extends towards the positioning groove 30 and crosses the positioning groove 30.

[0088] Continue to refer to the appendix Figure 4 , a tearing mark 32 is preset on the fixing strip 31, and the tearing mark 32 is located above the positioning groove 30.

[0089] Refer to the appendix Figure 5 , during the process that the two suction attachments 203 are inserted into the positioning groove 30 in a relatively contracted state and deformed downward, the suction cup 20 presses the fixing strip 31 to break the fixing strip 31 at the tearing mark 32. The positioning groove 30 is opened along the length direction of the glass substrate 4, and the slot width of the positioning groove 30 is not less than the width of the positioning block 202.

[0090] Refer to the appendix Figure 1 , at least one embodiment provides a glass substrate picking device, including: a glass substrate 4; a protective film 3, which covers the glass substrate 4 and is provided with a plurality of positioning grooves 30; a picking device 2, which is adapted to pick up the glass substrate 4 by negative pressure; the picking device 2 includes: a support frame 24; a suction cup 20, which is arranged at the lower end of the support frame 24, and the suction cup 20 includes two suction attachments 203 that are hinged to each other; a blowing structure 25, which is arranged near the suction cup 20 on the support frame 24, and one blowing structure 25 corresponds to one suction cup 20; wherein, after the support frame 24 drives the suction cup 20 to move above the positioning groove 30, the two suction attachments 203 flip and contract to insert into the positioning groove 30; the suction attachment 203 flips from the contracted state to the extended state in the positioning groove 30 to pick up the glass substrate 4 by negative pressure; when the glass substrate 4 is separated from the suction attachment 203, the suction attachment 203 limits the protective film 3 to separate the protective film 3 from the glass substrate 4.
