For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium.

[0033] All terms used in this application have the same meanings as those understood by those of ordinary skill in the art to which this application pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, for example, should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0034] Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the specification.

[0035] In a first aspect, as Figures 1 to 4As shown, in some embodiments of the present application, a sheet transfer assembly is provided, mainly including a carrier structure 10 and an anti-scratch structure 20. The carrier structure 10 is provided with a negative pressure cavity 11, negative pressure holes 12 and a carrier surface 13. The negative pressure holes 12 are arranged on the carrier surface 13 and communicate with the negative pressure cavity 11. The anti-scratch structure 20 is connected to the side of the carrier surface 13 away from the negative pressure cavity 11 and is provided with a plurality of communication holes 21, and at least one communication hole 21 communicates with the negative pressure hole 12.

[0036] The anti-scratch structure 20 is arranged to adapt to the surface of the contact sheet 30, protecting the surface of the sheet 30 from scratches. Combining the settings of the negative pressure holes 12 and the negative pressure cavity 11 can generate negative pressure to adsorb the sheet 30 on the anti-scratch structure 20, maintaining the structural stability between the sheet 30 and the anti-scratch structure 20. The above functions effectively protect the sheet 30 from two aspects: avoiding relative friction and preventing scratches that would affect the quality even if relative friction occurs, thereby outputting sheets 30 with better quality. This embodiment effectively solves the problem of the risk of scratches during the transfer of existing sheets in adjacent processes.

[0037] It can be understood that, compared with traditional technical solutions, the setting of the anti-scratch structure 20 avoids the direct contact between the carrier surface 13 and the sheet 30 and also isolates the adsorption position, avoiding the generation of adsorption marks at the position of the negative pressure holes 12 and improving the surface quality of the sheet 30. Although the communication holes 21 replace the negative pressure holes 12 for adsorption, they are located within the anti-scratch structure 20, which is equivalent to extending the negative pressure holes 12. This makes the adsorption have a certain buffer, and the contact between the material at the opening position of the communication holes 21 and the sheet 30 will not cause damage, meeting the requirements of stable transportation and protecting the sheet 30.

[0038] It should be noted that the number of communication holes 21 and negative pressure holes 12 can be inconsistent. Generally, the number of communication holes 21 is less than or equal to the number of negative pressure holes 12. Such a setting is used to ensure that the communication holes 21 can always generate negative pressure, and the connection between the negative pressure holes 12 and the outside is achieved through the communication holes 21, which is convenient for adjusting the generated negative pressure and adapting to sheets 30 of different sizes. At the same time, the relatively large number of negative pressure holes 12 can effectively reduce the actual mass of the carrier structure 10.

[0039] In some embodiments of the present application (not shown in the figure), the anti-scratch structure 20 is made of a non-stick material or a flexible material and is integrally formed on the carrier surface 13. The flexible material or non-stick material can adapt to the surface of the sheet 30 without causing relative sliding, damage or displacement on the surface of the sheet 30. The setting of the flexible material has a certain buffering effect and has certain buffering performance during the transfer process, avoiding the situation where the acting force is transferred to the sheet 30 when there is a collision or the like, resulting in material damage.

[0040] The flexible material can specifically be materials such as rubber and silica gel with self-lubricating properties, which can play an isolating role for the sheet 30. The sheet 30 can specifically be a glass sheet, a photovoltaic panel, etc.

[0041] Such as Figures 1 to 4 As shown, in some embodiments of the present application, the scratch-resistant structure 20 is a polytetrafluoroethylene coating integrally formed on the bearing surface 13. The scratch-resistant structure 20 arranged in this way can be made thinner, and it can also avoid excessive assembly, resulting in instability of the scratch-resistant structure 20 and abrasion of the sheet 30 during the transfer process. At the same time, after the coating is applied, the original negative pressure hole 12 position can be directly penetrated through the entire scratch-resistant structure 20 to form a communication hole 21. In this way, there is no need to perform alignment settings between the communication hole 21 and the negative pressure hole 12, so as to achieve a better communication effect, have a better effect when generating adsorption, and improve the position accuracy of the communication hole 21 and the matching degree.

[0042] It can be understood that the polytetrafluoroethylene coating, also commonly known as Teflon, has good non-sticking performance and chemical stability. When facing non-metallic materials, it can meet a stable transportation environment, is not easy to generate and store dirt, and makes the surface of the sheet 30 cleaner.

[0043] In some alternative embodiments (not shown in the figure), the polytetrafluoroethylene coating can be a pre-sprayed sheet structure or a coating directly sprayed on the bearing surface 13.

[0044] Such as Figures 5 to 7 As shown, in some embodiments of the present application, an installation groove 131 is provided on the bearing surface 13, and the polytetrafluoroethylene coating is integrally formed in the installation groove 131. This setting enables better control of the length and width of the polytetrafluoroethylene coating, provides good balance for the sheet transfer assembly, and facilitates stability during subsequent transfer processes.

[0045] It can be understood that the polytetrafluoroethylene coating can be a pre-sprayed sheet structure directly installed in the installation groove 131 or a coating directly sprayed on the bottom wall of the installation groove 131.

[0046] In some embodiments of the present application (not shown in the figure), the width of the polytetrafluoroethylene coating is adapted to the bearing surface 13, that is, less than or equal to the width of the bearing surface 13, and the length of the polytetrafluoroethylene coating can be set according to the actual size of the sheet 30 and the adsorption requirements. The negative pressure holes 12 on the corresponding bearing structure 10 need to be completely located under the polytetrafluoroethylene coating to ensure the adsorption effect.

[0047] Such as Figures 1 to 3As shown, in some embodiments of the present application, the sheet transfer assembly is provided with a negative pressure structure. The carrier structure 10 includes one or more negative pressure cavities 11, and the negative pressure cavities 11 are respectively provided with negative pressure interfaces 14. One or more negative pressure interfaces 14 are detachably connected to the output end of the negative pressure structure.

[0048] The setting of one or more negative pressure cavities 11 can correspond to one or more bearing surfaces 13, so as to meet the transportation requirements of different sheets 30. It can be understood that the placement surface of the sheet 30 is generally the upper and lower surfaces of its structure, with a large area span. A single bearing surface 13 needs to avoid the transfer assembly, so as to facilitate extending into the inside of the transfer assembly and located below the sheet 30, so as to take away the sheet 30. Therefore, the bearing surface 13 can be strip-shaped to facilitate extending into it, and multiple bearing surfaces 13 can cooperate with the lower surface of the same sheet 30.

[0049] In an alternative embodiment, please refer to Figure 1 and Figure 3 , multiple bearing surfaces 13 are connected to the connecting handle 16. The connecting handle 16 is used for assembling on a manipulator or a transmission component, and is specifically connected through the connecting counterbore 17 located above it to provide power output. The lengths of multiple bearing surfaces 13 are the same, and the lengths of the anti-scratch structures 20 corresponding to them above are also equal. Multiple bearing surfaces 13 combine to form a larger bearing area, so as to realize the function of bearing a larger-size sheet 30.

[0050] In an alternative embodiment, according to the length of the sheet, the number of the set bearing surfaces 13 can be controlled within 1 to 4, which can meet the requirement of reducing the output power of the negative pressure structure while meeting the requirement of adsorption stability.

[0051] As Figures 1 to 3 shown, in some embodiments of the present application, the carrier structure 10 includes multiple negative pressure cavities 11, and the multiple negative pressure cavities 11 are symmetrically distributed along the length direction of the carrier structure 10; and / or, the multiple negative pressure cavities 11 are symmetrically distributed along the width direction of the carrier structure 10.

[0052] The above settings make the adsorption effect on a single bearing surface 13 have high balance, provide good balance for the force acting on the area where the bearing surface 13 is located, and at the same time can meet the cooperation of sheets 30 with different spans in the length direction and width direction of the carrier structure 10 to meet the transfer of the sheets 30.

[0053] As Figure 3 and Figure 6As shown, in some embodiments of the present application, the negative pressure interface 14 is a threaded hole. The above setting realizes the detachable connection between the negative pressure interface 14 and the output end of the negative pressure structure. The threaded hole can form a stable threaded connection and form self-locking and sealing, making the interface inconvenient to operate, and the generated negative pressure is stable, which is beneficial to the adsorption of the sheet 30.

[0054] In some embodiments of the present application (not shown in the figure), the diameter of the communication hole 21 is less than or equal to 1 mm; and / or, the diameter of the negative pressure hole 12 is less than or equal to 1 mm. Such a setting makes the sizes of the communication hole 21 and the negative pressure hole 12 relatively small. By arranging a plurality of communication holes 21 and negative pressure holes 12 to adapt to the sheet 30, while satisfying the adsorption effect on the sheet 30, it can also ensure that no adsorption damage is caused to the sheet 30, such as adsorption marks.

[0055] It can be understood that since the sizes of the communication hole 21 and the negative pressure hole 12 are relatively small, the negative pressure effect generated in a single hole is effective, and the sheet 30 has a certain structural strength, so it will not directly cause damage to the sheet 30. At the same time, because the peripheral structures of the communication hole 21 and the negative pressure hole 12 have a relatively small aperture, they have a supporting part with a relatively high structural strength, that is, the structural strength of the bearing surface 13 is also improved, thereby providing a more stable adsorption effect and facilitating transportation and transfer.

[0056] As Figure 1 and Figure 2 As shown, in some embodiments of the present application, a reinforcing structure 15 is provided on the surface of the bearing structure 10 facing away from the anti-scratch structure 20. The setting of the reinforcing structure 15 is used to provide a better supporting effect. It can be understood that the setting of the negative pressure cavity 11 causes a negative pressure effect inside the negative pressure cavity 11. Affected by the atmospheric pressure, the peripheral side walls of the cavity all have a tendency to move inwardly. Therefore, it is necessary to enhance the overall structural strength. The bearing surface 13 cannot increase specific structures and needs to maintain the accuracy of the bearing surface 13 to facilitate cooperation with the sheet 30. And the two side surfaces need to pass through the transmission components of the production line and need to maintain a structural gap. Therefore, the reinforcing structure 15 needs to be provided on the surface of the bearing structure 10 facing away from the anti-scratch structure 20 to provide the overall structural strength of the negative pressure cavity 11.

[0057] It should be noted that the length of the reinforcing structure 15 is adapted to the actual length of the negative pressure cavity 11. Such a setting avoids a large weight change caused by the excessive length of the reinforcing structure 15, which is not conducive to transportation.

[0058] As Figure 1 and Figure 2As shown, in some embodiments of the present application, the thickness of the strengthening structure 15 is greater than or equal to the width of the bearing structure 10. Such a setting can better ensure the stability of the entire bearing structure 10. The movement range of the bearing structure 10 should be within the height and width ranges supported by the sheet 30 to avoid the bearing structure 10 hitting the machine.

[0059] In some alternative embodiments, along the direction away from the bearing surface 13 in the thickness direction of the strengthening structure 15, the width of the strengthening structure 15 gradually decreases from the width of the bearing structure 10 and is symmetrically arranged. Such a setting makes the cross-section of the strengthening structure 15 perpendicular to its length direction triangular, forming a relatively stable support. At the same time, the material used for the strengthening structure 15 is reduced, thereby improving the compactness and stability of the structure.

[0060] As Figures 1 to 7 As shown, some embodiments of the present application provide a sheet transfer assembly for transferring the sheet 30. Its shape is generally like a fork and mainly includes the following parts or components: a bearing structure 10, a negative pressure cavity 11, negative pressure holes 12, a bearing surface 13, a mounting groove 131, a negative pressure interface 14, a strengthening structure 15, a connecting handle part 16, a connecting counterbore 17, an anti-scratch structure 20, and a communication hole 21.

[0061] The sheet transfer assembly is provided with 4 "fork teeth", that is, it has four bearing surfaces 13. When the sheet transfer assembly reaches below the sheet 30, the negative pressure structure generates negative pressure and communicates with the negative pressure cavity 11 through the negative pressure interface 14. The negative pressure cavity 11 obtains negative pressure. At this time, a large number of negative pressure holes 12 with a size of less than 1 mm opened on the bearing surface 13 generate negative pressure and communicate to the surface of the sheet 30 through the communication holes 21 on the anti-scratch structure 20, generating an adsorption effect. After the sheet 30 is adsorbed, under the protection of the anti-scratch structure 20, the sheet 30 will not be scratched on the sheet transfer assembly, nor will the adsorption marks generated by the existing suction nozzles occur. The gap between adjacent bearing surfaces 13 can ensure that the sheet transfer assembly avoids the support columns at the placement position of the sheet 30 in the previous process during operation, preventing movement interference and resulting in unstable transfer of the sheet 30.

[0062] The bearing structure 10 is made of aluminum profile structure or stainless steel pipe material, which can ensure the structural strength from the material and reduce the weight. Since the entire sheet transfer assembly is relatively large in size, to ensure the cantilever stability when the fork sheet transfer assembly extends, a strengthening structure 15 is provided on the side of the negative pressure cavity 11 away from the bearing surface 13, which is equivalent to a reinforcing rib.

[0063] The operation process of the sheet transfer component for transferring the sheet 30 from this station to the next station is as follows: Driven by a servo motor or a manipulator, the sheet transfer component is inserted below the sheet 30 at this station. The bearing surface 13 avoids the supporting components of the sheet 30 and moves upward as a whole. The sheet is adsorbed by the bearing surface 13 to break away from the support at this station. When the sheet transfer component moves upward, the negative pressure structure is started at the same time, and the sheet 30 is successfully adsorbed onto the anti-scratch structure 20, and the adsorption operation is completed. The sheet transfer component moves to above the support of the next station through the power system. While descending, the negative pressure structure is closed, and the sheet 30 is placed on the support of the next station. The sheet transfer component continues to descend below the support and leaves this station, and the sheet transfer component completes the entire transfer process.

[0064] In a second aspect, the present application provides a production line for processing and manufacturing the sheet 30, including a first process, a second process, a power component, and the sheet transfer component in any of the above embodiments. The sheet transfer component is fixedly connected to the power component, and the power component drives the sheet transfer component to transfer the sheet 30 from the first process to the second process. For the beneficial effects of the sheet transfer group, please refer to the descriptions in the above embodiments and will not be elaborated here. The power component can specifically be a manipulator or a transmission structure, and the bearing structure 10 is detachably connected through the connecting counterbore 17 on its connecting handle portion 16.

To avoid obscuring the concept of the present application, some details well known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed here based on the above description.

Those skilled in the art should understand that the above embodiments can be modified or some technical features can be equivalently replaced without departing from the scope and spirit of the present application.
