[0002] With the development of science and technology, folding screen mobile phones gradually appear in the public's vision, and the research and production of ultra-thin glass used by folding screens gradually become the focus of major mobile phone glass manufacturers. The production process of ultra-thin flexible glass includes a hardening process. In the existing hardening process, the glass needs to be inserted into a hardening frame one by one. The hardening frame, as an auxiliary carrier, is an indispensable part of the hardening process. It can make the glass not overlap and stand in the hardening furnace perfectly, so that the glass can be fully hardened.

[0003] However, it is not easy to manually insert the product into the high-temperature hardening frame. It is known that the thickness of the ultra-thin flexible glass is about 0.03mm, and it is flexible, so the force control is very important. Therefore, manually inserting and pulling the ultra-thin flexible glass into the frame will easily cause cracks, scratches, breakage and other defects in the glass, resulting in low production yield of the process. In addition, during the production process, not only the operation method of the operator needs to be tested, but also the efficiency and individual differences of the operator need to be considered.

[0004] Due to the above reasons, the efficiency of the hardening process is low and the yield is difficult to guarantee. In short, for such fragile and flexible glass, manual insertion of the frame is not desirable. SUMMARY

The suction cup assembly 65 comprises: a suction cup base 652, the suction cup base 652 is provided with a first accommodation hole and a plurality of second accommodation holes; a vacuum air path suction plate 651 installed on the side of the suction cup base 652 away from the rotating arm 63, the surface of the suction cup base 652 away from the suction cup base 652 is provided with a plurality of first air holes, the surface of the suction cup base 652 facing the suction cup base 652 is provided with a second air hole corresponding to the first accommodation hole, the plurality of first air holes and the second air hole are in communication, and the second air hole is in communication with an external vacuum generator through a first connector 655 arranged in the first accommodation hole; a plurality of non-contact suction cups 654, the number of the non-contact suction cups 654 is consistent with the number of the second accommodation holes, the plurality of non-contact suction cups 654 are arranged in the plurality of second accommodation holes respectively, the surface of the non-contact suction cup 654 away from the rotating arm 63 is provided with a jet hole, and the surface of the non-contact suction cup 654 facing the rotating arm 63 is provided with an air inlet hole in communication with the jet hole; the suction cup fixing plate 653, the opposite sides of the suction cup fixing plate 653 are connected with the rotating arm 63 and the suction cup base 652 respectively, the suction cup fixing plate 653 is provided with a second connector 656 and a plurality of air flow communication holes in communication with the second connector 656, and the plurality of air flow communication holes are in one-to-one correspondence with the air inlet holes of the plurality of non-contact suction cups 654 respectively; and the second connector 656 is used to communicate with an external air supply device.

[0040] According to the above description, using the automatic rack inserting machine for ultra-thin flexible glass provided by the present embodiment to insert and place glass includes the following processes:

[0041] First, the glass stack is placed on the workbench 12 provided in the rack 1, and then the single-disk stack is placed on the transfer mechanism 3 by manual operation. The transfer mechanism 3 moves the single-disk stack from the loading position to the unloading position. The transfer module assembly 2 drives the transfer robot 6 to move to the first position. The transfer robot 6 sucks the glass in the single-disk stack. The transfer module assembly 2 drives the transfer robot 6 to move to the second position. The transfer robot 6 places the single glass on the secondary positioning mechanism 4. The secondary positioning mechanism 4 positions the glass to ensure accurate suction of the glass by the transfer robot 6. After positioning, the transfer robot 6 sucks the glass again. The transfer module assembly 2 drives the transfer robot 6 to move to the third position. The transfer robot 6 flips the glass from a horizontal position to a vertical position. The transfer module assembly 2 drives the transfer robot 6 to move vertically downward, so as to insert the glass into the rack 5. After insertion, the transfer robot 6 releases the glass. The transfer module assembly 2 drives the transfer robot 6 to move to the first position. At the same time, the next single-disk stack is placed on the transfer mechanism 3 by manual operation. In this way, the glass is sucked, positioned and inserted by mechanical automation, thereby reducing human intervention, greatly ensuring the accuracy, efficiency and production yield of the rack 5, and being not affected by the differences in people and operation methods.

[0042] It is worth mentioning that the transfer positioning bottom plate 33 is provided with positioning columns 34 at the four top corners. When the glass single-disk stack is placed on the upper end of the transfer positioning bottom plate 33 provided in the transfer mechanism 3, the positioning columns 34 at the four corners of the transfer positioning bottom plate 33 can be positioned and matched to realize preliminary positioning and placement, thereby ensuring the accuracy and stability of subsequent vacuum suction of the glass.

[0043] As described above, the cylinder positioning assembly 44 comprises a receiving seat 447 mounted on the cylinder fixing plate 446, and the receiving seat 447 and the cylinder 444 are located on opposite sides of the cylinder fixing plate 446, respectively. A guide bar 443 is slidably embedded on the upper side of the receiving seat 447, and the moving direction of the guide bar 443 is consistent with the extension direction of the extension shaft of the cylinder 444. A telescopic spring 448 is connected to the connecting block 445 and the bottom plate 41, respectively, and the positioning table 43 is designed with a hollow cavity and a blowing hole connected to the cavity. When the glass is placed on the positioning table 43 inside the secondary positioning mechanism 4, the positioning table 43 is blown by the internal cavity to achieve glass suspension, avoid glass placement scratches, and cooperate with the cylinder positioning assembly 44 installed on the four sides to achieve stable positioning of the glass. In addition, when the cylinder 444 is deflated, the push block 441 slowly approaches the glass under the back-pulling cooperation of the telescopic spring 448 inside, thereby accurately positioning the glass on the positioning table 43, and effectively preventing the push block 441 from causing damage to the glass due to excessive moving speed. Secondly, when the cylinder 444 is extended and retracted, the receiving seat 447 and the guide bar 443 can guide and cooperate to ensure accurate transmission and movement of the cylinder 444.

[0044] The vacuum airway suction plate 651 is installed on the side of the suction disc base 652 away from the rotating arm 63. The side of the suction disc base 652 away from the surface of the suction disc base 652 is provided with a plurality of first air holes. The surface of the suction disc base 652 facing the surface of the suction disc base 652 is provided with a plurality of second air holes corresponding to the first air holes. The first air holes and the second air holes are in communication. The second air holes are in communication with an external vacuum generator through a first connector 655 passing through the first air holes. A plurality of non-contact suction discs 654 are provided. The number of the non-contact suction discs 654 is consistent with the number of the second air holes. The non-contact suction discs 654 pass through the second air holes respectively. The surface of the non-contact suction disc 654 away from the rotating arm 63 is provided with a gas injection hole. The surface of the non-contact suction disc 654 facing the rotating arm 63 is provided with an air inlet hole in communication with the gas injection hole. The suction disc fixing plate 653 is connected to the rotating arm 63 and the suction disc base 652 respectively. The suction disc fixing plate 653 is provided with a second connector 656 and a plurality of air flow communication holes in communication with the second connector 656. The air flow communication holes are in one-to-one correspondence with the air inlet holes of the non-contact suction discs 654 respectively. The second connector 656 is used to communicate with an external air supply device. In addition, the surface of the non-contact suction disc 654 away from the rotating arm 63 is closer to the suction disc base 652 than the surface of the vacuum airway suction plate 651 away from the rotating arm 63. The surface of the vacuum airway suction plate 651 away from the rotating arm 63 is provided with a plurality of flow guide grooves. The opposite ends of each flow guide groove are in communication with the second air holes and the outside respectively. When sucking the glass, the gas injection hole of the non-contact suction disc 654 sprays gas. The gas spreads rapidly along the flow guide grooves from the center of the suction disc to the outside of the disc in the radial direction, forming a pressure difference, so that the glass product is suspended in the air. It mainly utilizes the Bernoulli principle: in water flow or air flow, the flow rate is fast, the pressure is small; the flow rate is slow, the pressure is large; when the upper surface of the glass near the gas injection hole has a large air flow rate and a small pressure, and the lower surface of the glass has a slow air flow rate and a large pressure, the glass will be lifted due to the pressure difference between the upper and lower surfaces, and will be suspended in the air. Therefore, when the glass at the upper end of the transfer mechanism 3 is to be sucked, the first connector 655 and the second connector 656 are connected to the vacuum generator and the air supply device respectively, so that the non-contact suction disc 654 and the suction disc fixing plate 653 cooperate with each other to realize the non-contact adsorption of the glass, so that the glass can be suspended and sucked, and the glass can be prevented from being scratched during the taking and placing process.

[0045] The embodiments of the application are described above with reference to the accompanying drawings, but the application is not limited to the above specific embodiments, which are merely illustrative and not restrictive, and a person of ordinary skill in the art can make many forms under the inspiration of the application without departing from the purpose of the application and the scope protected by the claims.
