[0059] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0060] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0061] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0062] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0063] like Figure 1 and Figure 2As shown, the present application provides a rotating mechanism 741, which includes a rotor 1 and a stator 2. The rotor 1 has a cavity 11, and the inner wall of the cavity 11 has a connecting portion 12, which is electrically connected to the rotor 1. The cavity 11 extends along the axial direction of the rotating mechanism 741 and can pass through the rotor 1, which is convenient for setting other circuit connection lines and components. The stator 2 is annular and is sleeved on the rotor 1. The rotor 1 can rotate relative to the stator 2. There is a certain gap between the rotor 1 and the stator 2 to avoid direct contact between the rotor 1 and the stator 2 and reduce friction between the two. The stator 2 has a connecting hole 21 and a connecting component 22. The connecting hole 21 passes through the stator 2 in the radial direction of the rotating mechanism 741. The connecting component 22 is installed in the connecting hole 21. The outer wall of the connecting hole 21 can extend outward in the radial direction of the rotating mechanism 741 to form a pipe shape, which is convenient for setting and installing the connecting component 22. At least a portion of the connecting assembly 22 is elastic, elastically abutting the rotor 1 and electrically connecting the connecting assembly 22 and the rotor 1. For example, the connecting assembly 22 may include an elastic metal portion and may be configured in a filamentous or sheet-like form, providing both elasticity and conductivity. The rotor 1 may be made of a conductive material such as copper. When the rotor 1 rotates relative to the stator 2, the connecting assembly 22 can maintain an electrical connection with the rotor 1, enabling continuous current or signal transmission without affecting the normal rotation of the rotor 1. The end of the connecting assembly 22 away from the rotor 1 may protrude relative to the outer wall of the stator 2 to facilitate electrical connection of other external circuits to the rotating mechanism 741.

[0064] In the rotating mechanism 741 provided in the embodiment of the present application, the rotor 1 and stator 2 are electrically connected via a connecting assembly 22, enabling rotation while also ensuring continuous signal or current transmission. During the rotation of the rotor 1, the rotor 1 can output current or signals via an external circuit connected to the connecting portion 12, which can be connected to a device or mechanism that rotates with the rotor 1. The connected circuit can rotate with the rotor 1, thereby reducing the possibility of circuit entanglement and improving equipment safety and production efficiency.

[0065] like Figure 2 As shown, in a possible embodiment, the rotating mechanism 741 includes a plurality of stators 2 and a plurality of rotors 1, and the plurality of stators 2 and the plurality of rotors 1 are stacked along the axial direction of the rotating mechanism 741, and insulating parts 3 are respectively provided between adjacent stators 2 and between adjacent rotors 1.

[0066] The rotating mechanism 741 provided in the embodiment of the present application is provided with a plurality of stators 2, and each stator 2 can be provided with a connecting assembly 22, which can realize circuit connection respectively and realize the simultaneous connection of multiple circuits, thereby meeting more practical needs and power transmission. Correspondingly, the rotating mechanism 741 is also provided with a plurality of rotors 1, which are respectively used to cooperate with the corresponding stators 2, and the plurality of rotors 1 can rotate synchronously. Adjacent rotors 1 and adjacent stators 2 are separated by insulating members 3, and the material of the insulating members 3 can be a material with insulating function such as plastic or rubber to avoid short circuits between adjacent rotors 1 or stators 2, thereby improving the safety of the rotating mechanism 741. Adjacent rotors 1 and adjacent stators 2 can be connected to each other by connecting members 222, such as bolts, etc., to improve the stability of their structure.

[0067] like Figure 3 As shown, in a possible embodiment, the connecting assembly 22 includes a mounting seat 221, a connecting member 222 and an elastic member 223, the mounting seat 221 is installed in the connecting hole 21, the elastic member 223 connects the mounting seat 221 and the connecting member 222, and the connecting member 222 abuts against the rotor 1.

[0068] At least a portion of the mounting seat 221 is mounted within the connection hole 21. The connection hole 21 may be threaded, and the mounting seat 221 may be threadedly mounted therein. One end of the mounting seat 221 protrudes from the outer wall of the stator 2 for connection to external circuitry. The other end of the mounting seat 221 is located within the connection hole 21 and is connected to the elastic member 223. The elastic member 223 is connected to the connector 222 and provides elastic force to the connector 222, enabling the connector 222 to maintain contact with the rotor 1 during rotation, thereby enabling the rotor 1 to achieve electrical connection with the connector 222 during rotation. The elastic member 223 may be a spring or a spring, and may be conductive to facilitate electrical connection between the mounting seat 221 and the connector 222. The elastic member 223 may be made of a metal or alloy with good elasticity and conductivity, such as copper, aluminum nickel iron alloy, steel, etc.

[0069] like Figure 3 As shown, in one possible embodiment, the connecting member 222 includes a main body 222a and a limiting portion 222b. The limiting portion 222b is provided on the outer wall of the main body 222a. One end of the elastic member 223 abuts against the mounting seat 221, and the other end abuts against the limiting portion 222b. The mounting seat 221 has a mounting groove 221a on a side close to the rotor 1, and the elastic member 223 is mounted in the mounting groove 221a.

[0070] The mounting seat 221 may be provided with a through hole, through which a portion of the main body 222a is provided, so that a portion of the main body 222a can extend outside the stator 2 for easy connection, and the mounting seat 221 can also limit the position of the connector 222. The main body 222a may be provided in a rod shape, and the limiting portion 222b is provided around the outer wall of the main body 222a. The limiting portion 222b is used to limit the position of the elastic member 223. The elastic member 223 may be a spring and is sleeved on the main body 222a. The elastic member 223 is located between the mounting seat 221 and the limiting portion 222b, and will not separate from the connector 222 and can maintain a relatively compressed state. This allows the elastic member 223 to continuously apply a thrust to the limiting portion 222b, thereby driving the connector 222, causing the connector 222 to maintain a tendency to move closer to the rotor 1, thereby maintaining the connector 222 in a state of connection with the rotor 1. Mounting slot 221a extends radially along mounting seat 221. Elastic member 223 can abut against the bottom wall of mounting slot 221a, with at least a portion of elastic member 223 located within mounting slot 221a, thereby limiting elastic member 223 and reducing the likelihood of separation between elastic member 223 and connector 222, thereby increasing the stability of elastic member 223 during deformation. A portion of mounting seat 221 can extend outside of stator 2 through connecting hole 21, electrically connecting mounting seat 221 and connector 222. External circuitry can be connected to mounting seat 221 to achieve electrical connection with connector 222.

[0071] like Figure 3 As shown, in a possible embodiment, part of the connecting member 222 extends from the connecting hole 21 to the outside of the stator 2, and a fixing member 224 is provided at one end of the connecting member 222, and a wiring portion 225 is provided between the fixing member 224 and the stator 2, and the wiring portion 225 is sleeved on the connecting member 222.

[0072] The portion of the main body 222a that extends outside the stator 2 can be used for external wiring. The wiring portion 225 is located outside the stator 2 and is sleeved on the main body 222a or the mounting base 221. The wiring portion 225 is electrically connected to the connector 222. The fixing member 224 can fix the wiring portion 225, and the provision of the fixing member 224 can limit the connector 222. The provision of the fixing member 224 can keep at least a portion of the main body 222a outside the cavity 11, thereby preventing the elastic member 223 from completely pushing the main body 222a out of the connecting hole 21 and disengaging it. In particular, during assembly or maintenance of the rotating mechanism 741, if the rotor 1 is not properly installed, the connector 222 cannot abut against the rotor 1. Therefore, under the push of the elastic member 223, the connector 222 is not blocked by the rotor 1 and may be separated from the stator 2, making it inconvenient to install or maintain it. When the fixing member 224 is provided, even if the rotor 1 does not abut against the connecting member 222 , the fixing member 224 or the connecting portion 225 can abut against the outer wall of the stator 2 , thereby limiting the connecting member 222 and facilitating assembly and maintenance of the rotating mechanism 741 .

[0073] like Figure 2 As shown, in a possible embodiment, the rotating mechanism 741 includes a support seat 4 and a bearing 5, the support seat 4 and the bearing 5 are located at the bottom of the rotor 1, the bearing 5 is sleeved on the support seat 4, and the rotor 1 is installed on the support seat 4 and can rotate with the support seat 4.

[0074] The support base 4 is used to support the rotor 1. At least a portion of the support base 4 can extend radially along the rotating mechanism 741 to facilitate support of the rotor 1. The support base 4 and the bearing 5 can be disposed inside the stator 2 to facilitate reducing the size of the rotating mechanism 741. The bearing 5 can be sleeved onto the support base 4, and the support base 4 and the rotor 1 can rotate relative to the bearing 5. The bearing 5 can improve the stability of the movement and the flexibility of the rotation of the rotor 1. The support base 4 can be provided with an opening along the axial direction of the rotating mechanism 741 to facilitate the installation of wiring through the support base 4.

[0075] like Figure 2 As shown, in a possible embodiment, the rotating mechanism 741 includes a rotating shaft 6, and the support seat 4 has a mounting hole 41, which extends along the axial direction of the rotating mechanism 741. The rotating shaft 6 is installed in the mounting hole 41 and can rotate with the mounting seat 221.

[0076] The rotating shaft 6 can be used to support other equipment that requires rotation. Through the connection portion 12, external wiring is connected to the equipment that requires electrical connection, enabling it to deliver current or transmit signals to the rotating equipment. One end of the rotating shaft 6, which passes through the mounting hole 41, can be connected to another drive device, such as a motor, to drive the rotating shaft 6. The rotating shaft 6 is connected to the support base 4, driving the support base 4, and further driving the rotor 1 to rotate. This allows the wiring to rotate synchronously with the rotor 1 during operation, reducing the possibility of entanglement.

[0077] like Figure 2 As shown, in a possible embodiment, the rotating shaft 6 has a support plate 63 , which is located at the bottom of the support seat 4 and the bearing 5 and abuts against the bearing 5 .

[0078] The support plate 63 is located on the inner side of the stator 2. The support plate 63 is used to support the bearing 5 and the support seat 4. The support plate 63 is provided with a through hole for easy connection with the rotating shaft 6. The support plate 63 can rotate with the mounting seat 4 and the bearing 5 and support both of them, so that they remain stable during rotation.

[0079] like Figure 2 As shown, in a possible embodiment, the rotating shaft 6 includes a ventilation pipe 61 , which passes through the rotating shaft 6 along the axial direction of the rotating mechanism 741 , and has ventilation joints 62 at both ends of the ventilation pipe 61 .

[0080] The ventilation line 61 enables pneumatic transmission, for example, by connecting to a cylinder drive. Through pneumatic and electric transmission, different power transmissions can be achieved, meeting a wide range of practical needs. The ventilation connector 62 has good airtightness, which can reduce the possibility of air leakage and facilitates connection to other pipelines for power transmission. The ventilation connector 62 can rotate relative to the rotating shaft 6. When the rotating shaft 6 rotates, the ventilation line 61 can be reduced from becoming entangled, which helps improve processing efficiency and safety.

[0081] like Figure 4 As shown, the present application provides a processing device 7, which includes a rotating mechanism 741. The rotating mechanism 741 is the rotating mechanism of any of the above embodiments.

[0082] The processing equipment 7 includes a loading and transporting device 71, a unloading and transporting device 72, a supply and transporting device 73, and a sleeve device. The processing equipment 7 is used to combine protective parts with products, such as sleeves of rubber plugs on the surface of products to achieve the protection function of the product surface. In automated production, the equipment needs to work alternately and reciprocatingly to continuously sleeve protective parts on the products. Therefore, it is necessary to set a rotating device to continuously switch and transfer products and protective parts, and rotate the products that have been sleeved to other positions, and rotate the unsleeved products to the designated positions to achieve sleeves. During the rotation process, the rotating mechanism 741 can not only realize the rotation function, but also supply power or air to the rotating device, and can reduce the possibility of entanglement of lines and pipes, which is conducive to improving processing efficiency and safety.

[0083] The loading and transporting device 71 is used to transport products without protective parts to a specified preset position to facilitate the combination of protective parts and products by the protective parts installation equipment. The unloading and transporting device 72 is used to transport products with protective parts installed. The supply and transporting device 73 is used to transport protective parts.

[0084] like Figure 5 As shown, the sleeve device includes a rotating device 74, which includes a support plate 742 and a rotating mechanism 741. The support plate 742 is connected to the rotating shaft and can rotate with the rotating shaft. The rotating mechanism 741 can be connected to an external circuit to supply air or electricity to the fixed tool 743 on the support plate 742. The fixed tool 743 is used to clamp and fix the workpiece or protective part. This can be achieved by setting a claw, and the claw is driven to tighten or loosen by a motor or cylinder. The support plate 742 can be equipped with multiple fixed tools 743 to fix multiple products. By rotating, the protective parts of the products can be installed in turn, thereby achieving higher work efficiency.

[0085] like Figure 4As shown, the sleeve device also includes a first clamp 75, a second clamp 76, a third clamp 77 and a fourth clamp 78. The first clamp 75 is used to clamp the product from the feeding and transporting device 71, move the product to the rotating device 74, and fix the product by fixing the tool 743. The processing equipment 7 includes at least two rotating devices 74, one rotating device 74 is used to fix and rotate the product, and the other rotating device 74 is used to fix and rotate the protective part. The second clamp 76 clamps the protective part from the supply and transporting device 73 and transports the protective part to the rotating device 74, where it is fixed by the tool and rotates with the pallet 742. The rotating device 74 can rotate continuously, so that the product or protective part on the pallet 742 can also be continuously rotated to the appropriate position for use in the next process, so that the fourth clamp 78 can assemble the product and protective part. Specifically, the fourth clamp 78 first grasps a product from the fixed fixture 743. The fourth clamp 78 can rotate to rotate the product's position for subsequent assembly with the protective element. The rotating mechanism 741 drives the support plate 742 to rotate, causing the fixed fixture 743 holding the product to rotate to a predetermined position, facilitating the next product grip by the fourth clamp 78. Furthermore, the fourth clamp 78 moves the product to a position adjacent to another rotating device 74, which holds the protective element, and drives the product to install it into the groove of the protective element, connecting the two and completing the assembly. Finally, the third clamp 77 holds the assembled product and protective element and places them on the unloading and transporting device 72, which transports them to another location for subsequent operations.

[0086] An embodiment of the present application provides a rotating mechanism 741 and a processing device 7. The rotating mechanism 741 includes a rotor 1 and a stator 2. The rotor 1 has a cavity 11. The inner wall of the cavity 11 has a connecting portion 12. The connecting portion 12 is electrically connected to the rotor 1. The stator 2 is annular and is sleeved on the rotor 1. The rotor 1 can rotate relative to the stator 2. The stator 2 has a connecting hole 21 and a connecting component 22. The connecting hole 21 passes through the stator 2 along the radial direction of the rotating mechanism 741. The connecting component 22 is installed in the connecting hole 21. At least part of the connecting component 22 is elastic. The connecting component 22 elastically abuts against the rotor 1, and the connecting component 22 is electrically connected to the rotor 1. The rotating mechanism can maintain electrical connection while rotating, and can reduce the possibility of wiring harness entanglement, which is conducive to improving production efficiency.

[0087] The above describes in detail the structure, features and effects of the present application based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present application, but the present application does not limit the scope of implementation to what is shown in the drawings. Any changes made in accordance with the concept of the present application, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present application.
