Unless otherwise specified, "plurality" means two or more.

[0047] As described in the background technology of the present application, in the related art, photovoltaic cells will generate certain static electricity during transportation and diffusion high-temperature processes. In the related art, since the photovoltaic cells are transported between the carrier box and the quartz boat by adsorption and transportation using ceramic suction cups, and due to the non-conductivity of ceramics at room temperature, the static electricity of the photovoltaic cells cannot be eliminated. In this way, there will be additional electrostatic adsorption force between the photovoltaic cells, and the electrostatic adsorption force will cause damage to the photovoltaic cells, such as scratches, fragmentation or hidden cracks.

[0048] In the related art, static electricity on photovoltaic cells is usually eliminated using a static electricity eliminator. Specifically, the static electricity eliminator will ionize air molecules to produce positive and negative ions, which will be blown to the surface of the photovoltaic cells to neutralize the positive and negative static electricity on the surface of the photovoltaic cells. However, the static electricity eliminator has the problem of slow static electricity removal speed and easy residual static electricity.

[0049] In view of the above-mentioned problems, the present application provides a suction cup to solve the problem that the static electricity elimination rod in the related art has a slow static electricity removal speed and is prone to residual static electricity.

[0050] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings:

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, the suction cup 100 includes a suction cup unit 1 and a contact conductor 2 ( Figure 2 and Figure 3 As shown), the suction cup unit 1 is used to adsorb and fix the adsorbed part 3, the contact conductor 2 is arranged on the suction cup unit 1, and the contact conductor 2 is used to contact the adsorbed part 3 adsorbed and fixed on the suction cup unit 1, so that the electrostatic charge on the adsorbed part 3 can be transferred to the contact conductor 2, and the contact conductor 2 is also used to be electrically connected to the grounding conductor (not shown in the figure) so that the electrostatic charge transferred to the contact conductor 2 can be transferred to the ground.

[0052] In the present application, since a contact conductor 2 is provided on the suction cup unit 1 in the suction cup 100, and since the contact conductor 2 is not only used to contact the adsorbed part 3 adsorbed and fixed to the suction cup unit 1, but also used to be electrically connected to the grounding conductor, when the suction cup 100 in the present application adsorbs the photovoltaic cell, the photovoltaic cell is the adsorbed part 3, and after the suction cup unit 1 adsorbs the photovoltaic cell, the electrostatic charge on the photovoltaic cell can be transferred to the contact conductor 2 in contact with it, and the electrostatic charge transferred to the contact conductor 2 can be transferred to the grounding conductor electrically connected to it, so that the electrostatic charge can be transferred to the grounding conductor via the grounding conductor, which can eliminate the static electricity on the photovoltaic cell, and then eliminate the electrostatic adsorption force between the photovoltaic cells, which can avoid damage to the photovoltaic cell due to the electrostatic adsorption force.

[0053] In the present application, since the attracted part 3 can be connected to the earth via the contact conductor 2 and the grounding conductor, basically, all the electrostatic charges on the attracted part 3 can be directly transferred to the earth via the contact conductor 2 and the grounding conductor. Compared with the static elimination rod in the related art, not only is there no need for the three static elimination processes of ionizing air, blowing the ionized air to the attracted part 3 to generate positive ions and negative ions, and neutralizing the electrostatic charges on the attracted part with the positive ions and negative ions, but also the problem of residual static electricity on the attracted part 3 due to the failure of the positive ions and negative ions to completely neutralize the electrostatic charges on the attracted part 3 can be avoided. Therefore, to a certain extent, the present application can not only simplify the process of static electricity elimination, which is beneficial to increase the elimination speed of static electricity on the attracted part 3, but also help to avoid the problem of residual static electricity on the attracted part 3.

[0054] For the suction cup unit 1, in a preferred embodiment, as Figure 1 , Figure 2 as well as Figure 3 As shown, the suction cup unit 1 is a ceramic suction cup, and the suction cup unit 1 includes an F-shaped suction cup unit and an E-shaped suction cup unit. By arranging the F-shaped suction cup unit and the E-shaped suction cup unit in one suction cup 100, they can be flexibly selected and used in combination according to specific needs and environments, thereby increasing the flexibility of the suction cup 100.

[0055] In other embodiments, the suction cup unit 1 includes an F-shaped suction cup unit or an E-shaped suction cup unit. Such an arrangement can simplify the composition of the suction cup unit 1 and facilitate the processing and manufacturing of the suction cup unit 1.

[0056] In other embodiments, the suction cup unit 1 can also be a rubber suction cup, a metal suction cup or a plastic suction cup. The type of the suction cup unit 1 can be selected flexibly. Specifically, it can be selected according to actual usage requirements. The embodiments of the present application will not be elaborated on this.

[0057] In addition, it should be noted that the structure of the suction cup unit 1, in addition to the F-shaped suction cup unit and the E-shaped suction cup unit, can also be a suction cup of any other structure, and the embodiments of the present application do not make specific limitations on this.

[0058] As for the attracted object 3, it should be noted that, in the embodiment of the present application, the attracted object 3 may not only be a photovoltaic cell sheet, but also other types of batteries or any other object with static electricity.

[0059] As for the grounding conductor, it should be noted that, in the embodiments of the present application, the grounding conductor may not only be a wire, but also any other conductive object.

[0060] For the suction cup 100, further, in a preferred embodiment, as Figure 1 , Figure 2 as well as Figure 3 As shown, the suction cup 100 also includes a mounting assembly 5, the suction cup unit 1 is arranged on the mounting assembly 5, the contact conductor 2 is electrically connected to the mounting assembly 5, and the mounting assembly 5 is used to be electrically connected to the grounding conductor so that the contact conductor 2 and the grounding conductor are indirectly electrically connected.

[0061] Such arrangement, through the installation component 5, not only facilitates the installation of the suction cup unit 1 in the suction cup 100, but also eliminates the need for the contact conductor 2 to be directly connected to the grounding conductor, which is beneficial to reducing the size of the contact conductor 2 and further beneficial to saving the manufacturing material of the contact conductor 2.

[0062] In other embodiments, the contact conductor 2 is directly connected to the ground conductor. This configuration can simplify the connection structure between the contact conductor 2 and the ground conductor, thereby facilitating the electrical connection between the contact conductor 2 and the ground conductor.

[0063] Further, in a preferred embodiment, Figure 2 and Figure 3As shown, the mounting assembly 5 includes a base 51, a cover plate 52 and a gasket 53. The base 51 is provided with a slot (not shown) penetrating the base 51. The suction cup unit 1 has an adsorption portion 11 and an insertion portion 12. The adsorption portion 11 is used to adsorb and fix the adsorbed component 3, and the insertion portion 12 is inserted into the slot. The cover plate 52 is arranged on a side of the base 51 away from the adsorption portion 11 to block the notch of the slot. The gasket 53 is arranged between the cover plate 52 and the base 51, and the gasket 53 is also arranged between the insertion portion 12 and the cover plate 52.

[0064] The cover plate 52 is a conductor cover plate, and / or the base 51 is a conductor base; the conductor cover plate and / or the conductor base are used to be electrically connected to the grounding conductor, so that the mounting assembly 5 is electrically connected to the grounding conductor, and the contact conductor 2 is electrically connected to the conductor cover plate and / or the conductor base.

[0065] In this way, the mounting assembly 5 composed of the base 51, the cover plate 52 and the gasket 53 not only facilitates the installation and removal of the suction cup unit 1 on the mounting assembly 5, but also protects the suction cup unit 1 through the gasket 53, which helps to prevent the suction cup unit 1 from being damaged due to interference with the cover plate 52. In addition, the electrical connection between the mounting assembly 5 and the grounding conductor and the contact conductor 2 is facilitated by the conductor cover plate and / or the conductor base.

[0066] In other embodiments, the mounting assembly 5 is a metal block, and a threaded hole for threadedly mating with a bolt is provided on the metal block, and a connecting ear is provided on the suction cup unit 1, and a through hole corresponding to the threaded hole and for the bolt to pass through is provided on the connecting ear, so that the suction cup unit 1 can be installed on the mounting assembly 5 by passing the bolt through the through hole and threadedly mating with the threaded hole. Such a configuration can simplify the structure of the mounting assembly 5, which is conducive to facilitating the processing and manufacturing of the mounting assembly 5.

[0067] Furthermore, the cover plate 52 is a conductor cover plate, the gasket 53 is a conductive gasket, and the gasket 53 contacts the cover plate 52 and the contact conductor 2 , so that the contact conductor 2 and the cover plate 52 are electrically connected through the gasket 53 .

[0068] The gasket 53 as a conductive gasket can not only protect the suction cup unit 1, but also realize the electrical connection between the contact conductor 2 and the cover plate 52, which facilitates the electrical connection between the contact conductor 2 and the cover plate 52. The contact conductor 2 is indirectly electrically connected to the grounding conductor through the gasket 53 and the cover plate 52, so there is no need to set a channel structure on the installation component 5 for avoiding the electrical connection between the contact conductor 2 and the grounding conductor, which can make full use of the existing structure of the installation component 5, and is conducive to simplifying the structure of the installation component 5, and is also conducive to facilitating the electrical connection between the contact conductor 2 and the grounding conductor.

[0069] In other embodiments, the contact conductor 2 contacts the cover plate 52. In this case, the gasket 53 may not be a conductive gasket. In this configuration, since the gasket 53 may not be a conductive gasket, the cost of the gasket 53 can be reduced.

[0070] In a preferred embodiment, the gasket 53 is a conductive silicone gasket. This configuration not only enables the gasket 53 to have good conductivity, but also enables the gasket 53 to have good elasticity, flexibility, shock absorption and buffering effects, thereby helping to extend the service life of the gasket 53 and enhancing the conductive effect of the gasket 53 and the protective effect on the suction cup unit 1.

[0071] In other embodiments, the gasket 53 may also be a conductive rubber gasket, a conductive sponge gasket or a conductive foam gasket. The material type of the gasket 53 is relatively flexible, and can be selected according to actual use requirements, which will not be elaborated in detail in the embodiments of the present application.

[0072] For the suction cup unit 1, further, in a preferred embodiment, the suction cup unit 1 has an adsorption surface (not marked in the figure) for contacting the adsorbed part 3, and the contact conductor 2 has a contact surface for contacting the adsorbed part 3; an installation groove (not shown in the figure) is provided on the adsorption surface, and the contact conductor 2 is installed in the installation groove so that the contact surface is coplanar with the adsorption surface.

[0073] With such a configuration, the contact surface of the contact conductor 2 and the adsorption surface of the suction cup unit 1 can be integrated into one surface, so that when the sucked part 3 is adsorbed on the adsorption surface, effective contact between the contact surface and the sucked part 3 can be ensured, and thus effective transfer of electrostatic charge on the sucked part 3 to the contact conductor 2 can be ensured. At the same time, to a certain extent, the space occupied by the contact conductor 2 and the suction cup unit 1 can be reduced, which is conducive to the convenience of setting the contact conductor 2 and the suction cup unit 1. Through the installation groove, not only can the reliability of the contact conductor 2 on the suction cup unit 1 be guaranteed, but also the corresponding structure of the coplanar arrangement of the contact surface and the adsorption surface on the suction cup unit 1 can be simplified, which is conducive to the convenience of processing the suction cup unit 1.

[0074] In other embodiments, a mounting groove is provided on the surface of the suction cup unit 1 that is opposite to the suction surface, a connecting hole is provided between the mounting groove and the suction surface, the contact conductor 2 is installed in the mounting groove, and the contact conductor 2 has a contact portion that extends out of the connecting hole and contacts the suctioned component 3, and the contact surface is provided on the contact portion. Such a configuration can, to a certain extent, reduce the influence of the coplanar configuration of the contact surface and the suction surface on the suction surface structure, thereby facilitating the suction effect of the suction surface on the suctioned component 3.

[0075] Regarding the contact conductor 2, further, in a preferred embodiment, the contact conductor 2 is a polyetheretherketone (PEEK) conductor.

[0076] Since polyetheretherketone has good wear resistance, using polyetheretherketone conductor as the contact conductor 2 can not only ensure the conductive effect, but also enhance the wear resistance of the contact conductor 2, thereby facilitating extending the service life of the contact conductor 2.

[0077] In other embodiments, the contact conductor 2 may also be a conductive rubber conductor, a conductive silicone conductor or a carbon-based material conductor. The material type of the contact conductor 2 is relatively flexible and can be selected according to actual use requirements. This embodiment of the present application will not be elaborated in detail.

[0078] like Figure 4 As shown, in a preferred embodiment, the suction cup 100 further includes a static eliminator 6 .

[0079] The static eliminator 6 can ionize the air into positive ions and negative ions, which can then neutralize the positive ions and negative ions with the positive and negative electrostatic charges on the attracted object 3. In this way, the electrostatic charge on the attracted object 3 can be eliminated through the dual means of the contact conductor 2 and the static eliminator 6, which can not only further accelerate the speed of static elimination, but also further ensure the static elimination effect.

[0080] In a preferred embodiment, Figure 1 As shown, the suction cup 100 further includes a driving mechanism 4 and at least two groups of suction cup unit groups, each suction cup unit group includes a plurality of suction cup units 1, and the driving mechanism 4 is used to drive each suction cup unit group to move closer to or away from each other.

[0081] Such arrangement, through at least two groups of suction cup unit groups, is conducive to the suction cup 100 to simultaneously absorb and fix more suctioned parts 3, which is only conducive to improving work efficiency. The driving mechanism 4 facilitates the adjustment of the position of each suction cup unit group, thereby facilitating the suction and fixing of each suction cup unit 1 in each suction cup unit group.

[0082] In a preferred embodiment, a plurality of F-shaped suction cup units are arranged at intervals, and each F-shaped suction cup unit forms a group of F-shaped suction cup unit groups; a plurality of E-shaped suction cup units are arranged at intervals, and each E-shaped suction cup unit forms a group of E-shaped suction cup unit groups, that is, two groups of suction cup unit groups are arranged, and the driving mechanism 4 is used to drive the F-shaped suction cup unit group and the E-shaped suction cup unit group to approach or move away from each other to perform separation and combination actions. The driving mechanism 4 is a prior art and will not be elaborated on in detail in the embodiments of the present application.

[0083] With such arrangement, the position adjustment of the F-shaped suction cup unit group and the E-shaped suction cup unit group is facilitated through the driving mechanism 4, which is not only conducive to facilitating the suction cup unit 1 in a single suction cup unit group to adsorb and fix the sucked part 3, but also conducive to facilitating the two suction cup units 1 in the two suction cup unit groups to jointly adsorb and fix the same sucked part 3.

[0084] Regarding the number of suction cup unit groups, in other embodiments, the suction cup unit groups can also be provided with one group, three groups, four groups or more. The number of suction cup unit groups can be set flexibly. Specifically, it can be determined according to actual usage requirements. The embodiments of the present application will not elaborate on this.

[0085] The present application also provides a loading and unloading device 1000, such as Figure 5 As shown, the loading and unloading equipment 1000 includes a suction cup 100.

[0086] In the present application, since the attracted part 3 can be connected to the earth via the contact conductor 2 and the grounding conductor, basically, all the electrostatic charges on the attracted part 3 can be directly transferred to the earth via the contact conductor 2 and the grounding conductor. Compared with the static elimination rod in the related art, not only is there no need for the three static elimination processes of ionizing air, blowing the ionized air to the attracted part 3 to generate positive ions and negative ions, and neutralizing the electrostatic charges on the attracted part with the positive ions and negative ions, but also the problem of residual static electricity on the attracted part 3 due to the failure of the positive ions and negative ions to completely neutralize the electrostatic charges on the attracted part 3 can be avoided. Therefore, to a certain extent, the present application can not only simplify the process of static electricity elimination, which is beneficial to increase the elimination speed of static electricity on the attracted part 3, but also help to avoid the problem of residual static electricity on the attracted part 3.

[0087] Furthermore, if Figure 5 As shown, the loading and unloading equipment 1000 also includes a mechanical arm 200, and the mechanical arm 200 has a mobile end, and the suction cup 100 is arranged at the mobile end. In this way, the mechanical arm 200 facilitates the flexible adjustment of the spatial position of the suction cup 100.

[0088] In other embodiments, the loading and unloading device 1000 may further include a guide rail and a slider, and the suction cup 100 is slidably arranged on the guide rail through the slider, so that the suction cup 100 can adjust the spatial position through the guide rail and the slider. Such an arrangement can simplify the mechanism for driving the suction cup 100 to adjust the spatial position, which is conducive to reducing the manufacturing cost.

[0089] It should be noted that, in addition to the robot arm 200, the mechanism for realizing spatial position adjustment of the suction cup 100 may be any other mechanism, and the embodiment of the present application does not make any specific limitation on this.

[0091] In the present application, since the attracted part 3 can be connected to the earth via the contact conductor 2 and the grounding conductor, basically, all the electrostatic charges on the attracted part 3 can be directly transferred to the earth via the contact conductor 2 and the grounding conductor. Compared with the static elimination rod in the related art, not only is there no need for the three static elimination processes of ionizing air, blowing the ionized air to the attracted part 3 to generate positive ions and negative ions, and neutralizing the electrostatic charges on the attracted part with the positive ions and negative ions, but also the problem of residual static electricity on the attracted part 3 due to the failure of the positive ions and negative ions to completely neutralize the electrostatic charges on the attracted part 3 can be avoided. Therefore, to a certain extent, the present application can not only simplify the process of static electricity elimination, which is beneficial to increase the elimination speed of static electricity on the attracted part 3, but also help to avoid the problem of residual static electricity on the attracted part 3.
