[0051] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0052] It is readily understood that, based on the technical solution of this application, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of this application. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this application and should not be considered as the entirety of this application or as limitations or restrictions on the technical solution of the application.

[0053] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0054] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meanings of the above in this application according to the specific circumstances.

[0055] One embodiment of the present invention discloses a tightening assembly, such as... Figure 1 As shown, it includes a sleeve 1 for connection with fasteners, a drive shaft 2, a drive sleeve 3, a first drive device 4, and a second drive device 5.

[0056] Sleeve 1 is detachably connected to drive shaft 2. Drive sleeve 3 is movably sleeved on drive shaft 2. Drive shaft 2 can move along the axial direction of drive sleeve 3 and can rotate relative to drive sleeve 3. First drive device 4 is connected to drive shaft 2 and is used to drive drive shaft 2 to move along the axial direction. Second drive device 5 is connected to drive sleeve 3 and is used to drive sleeve 3 to rotate around its axis.

[0057] like Figure 2 As shown, a clutch mechanism is provided between the transmission shaft 2 and the transmission sleeve 3. The clutch mechanism includes a first limiting member 24 and a second limiting member 31. The first limiting member 24 is disposed in the circumferential direction of the transmission shaft 2, and the second limiting member 31 is disposed in the circumferential direction of the transmission sleeve 3.

[0058] During transmission, the first limiting member 24 is connected to the second limiting member 31 and restricts the relative rotation of the transmission shaft 2 and the transmission sleeve 3;

[0059] When not in operation, the first limiting member 24 separates from the second limiting member 31, and the transmission shaft 2 and the transmission sleeve 3 can rotate relative to each other.

[0060] Furthermore, such as Figure 2 As shown, sleeve 1, drive shaft 2, and drive sleeve 3 are arranged on the same axis. The end of drive shaft 2 is detachably connected to sleeve 1. When drive shaft 2 rotates, it can drive sleeve 1 to rotate. Drive sleeve 3 is sleeved on drive shaft 2, allowing drive sleeve 3 to slide relative to drive shaft 2 along its axial direction and drive shaft 2 and drive sleeve 3 to rotate relative to each other around their axis. A clutch mechanism is provided between drive shaft 2 and drive sleeve 3, enabling transmission between drive shaft 2 and drive sleeve 3 so that drive shaft 2 and drive sleeve 3 can rotate synchronously.

[0061] In this application, when tightening the fasteners on the hinge, the sleeve 1 connects to the fastener, and then the first driving device 4 drives the transmission shaft 2 to move axially towards the transmission sleeve 3, so that the first limiting member 24 and the second limiting member 31 are connected. This allows the transmission shaft 2 and the transmission sleeve 3 to rotate synchronously. That is, the second driving device 5 drives the transmission sleeve 3 to rotate, the transmission sleeve 3 drives the transmission shaft 2 to rotate, and the transmission shaft 2 drives the sleeve 1 to rotate, thereby achieving the function of tightening the fasteners. This solves the problem of manual tightening in the prior art, improves work efficiency, and reduces the workload of workers. In addition, when it is necessary to fill the fastener into the sleeve 1 or after the fastener installation is completed, the first driving device 4 drives the transmission shaft 2 to slide away from the transmission sleeve 3, thereby separating the first limiting member 24 and the second limiting member 31. At this time, there is no transmission between the transmission sleeve 3 and the transmission shaft 2, so that the sleeve 1 does not rotate, which facilitates separation from the installed fasteners and insertion of the fasteners into the sleeve 1. This application eliminates the need for manual tightening of fasteners, thereby improving the installation efficiency of hinges.

[0062] In some embodiments of the present invention, such as Figure 2 As shown, the transmission shaft 2 includes a first linkage shaft 21 and a second linkage shaft 22. The first linkage shaft 21 and the second linkage shaft 22 are connected by a sliding sleeve 23. The transmission sleeve 3 is sleeved on the sliding sleeve 23. The first limiting member 24 is disposed on the first linkage shaft 21. The first driving device 4 is connected to the first linkage shaft 21. The sleeve 1 is detachably connected to the second linkage shaft 22.

[0063] Furthermore, such as Figure 2 As shown, the first linkage shaft 21, the second linkage shaft 22, and the sliding sleeve 23 are all on the same axis. The outer circumferential surface of the sliding sleeve 23 is cylindrical. The transmission sleeve 3 is fitted onto the sliding sleeve 23, allowing the sliding sleeve 23 and the transmission sleeve 3 to rotate relative to each other and slide relative to each other along the axis. The first linkage shaft 21 and the second linkage shaft 22 are connected by the sliding sleeve 23, enabling them to rotate synchronously. When it is necessary to tighten / loosen fasteners, the first drive device 4 drives the first linkage shaft 21 to move axially, causing the first limiting member 24 on the first linkage shaft 21 to move and engage with the second limiting member 31 on the transmission sleeve 3, thereby enabling transmission between the transmission sleeve 3 and the first linkage shaft 21.

[0064] In some embodiments of the present invention, such as Figure 2 As shown, the first linkage shaft 21 is provided with a first rotation limiting part 211, the second linkage shaft 22 is provided with a second rotation limiting part 221, and the transmission sleeve 3 is sleeved on the first rotation limiting part 211 and the second rotation limiting part 221.

[0065] The first rotation limiting part 211 is slidably connected along the axial direction of the sliding sleeve 23. The first rotation limiting part 211 and the sliding sleeve 23 are fixed in the circumferential direction and restrict the relative rotation of the first rotation limiting part 211 and the sliding sleeve 23.

[0066] The second rotation limiting part 221 is slidably connected along the axial direction of the sliding sleeve 23. The second rotation limiting part 221 and the sliding sleeve 23 are fixed in the circumferential direction and restrict the relative rotation of the second rotation limiting part 221 and the sliding sleeve 23.

[0067] Furthermore, square holes are provided at both ends of the sliding sleeve 23 along the axial direction. The first rotation limiting part 211 is provided at the end of the first linkage shaft 21, and the second rotation limiting part 221 is provided at the end of the second linkage shaft 22. The first rotation limiting part 211 and the second rotation limiting part 221 match the shape of the square holes in the sliding sleeve 23. The first rotation limiting part 211 and the second rotation limiting part 221 are inserted into the square holes, so that the first rotation limiting part 211 and the second rotation limiting part 221 are respectively fixed relative to the sliding sleeve 23 in the circumferential direction, that is, the first linkage shaft 21, the second linkage shaft 22 and the sliding sleeve 23 can rotate synchronously. In addition, the first rotation limiting part 211 and the second rotation limiting part 221 can slide along the axial direction of the square hole. Therefore, when the first driving device 4 drives the first linkage shaft 21 to move axially, it will not drive the sliding sleeve 23 and the second linkage shaft 22 to move axially. In this way, the sleeve 1 will not move axially. Therefore, it can avoid the sleeve 1 moving a greater distance axially than the fastener is screwed in during the tightening process, which would cause damage to the hinge.

[0068] Optionally, a connecting hole is provided inside the sleeve 1. The connecting hole is a circular hole, and a groove is provided on the inner wall of the connecting hole. The first rotation limiting part 211 and the second rotation limiting part 221 are locking blocks provided in the circumferential directions of the first linkage shaft 21 and the second linkage shaft 22, respectively. The groove is provided axially, and the locking block is inserted into the groove and can slide along the groove. When the first driving device 4 drives the first linkage shaft 21 to slide axially, the locking block can slide along the groove. When the transmission sleeve 3 drives the first linkage shaft 21 and drives the first linkage shaft 21 to rotate, the first linkage shaft 21 drives the sliding sleeve 23 to rotate, and then drives the second linkage shaft 22 to rotate through the sliding sleeve 23.

[0069] In some embodiments of the present invention, such as Figure 2 As shown, the first limiting member 24 includes a plurality of first locking blocks, which are respectively arranged at intervals along the circumference of the first linkage shaft 21. The second limiting member 31 includes a plurality of first locking slots that match the first locking blocks. The first locking slots are arranged at the end of the sleeve 1, and the plurality of first locking slots are arranged at intervals along the circumference of the sleeve 1.

[0070] During transmission, the first locking block engages with the first locking slot.

[0071] Furthermore, during transmission, the first drive device 4 drives the first linkage shaft 21 to move toward the transmission sleeve 3, thereby causing the first locking block to engage in the first locking slot, which in turn restricts the relative rotation of the first linkage shaft 21 and the transmission sleeve 3, thereby enabling the transmission sleeve 3 to drive the first linkage shaft 21 to rotate.

[0072] Furthermore, the edge of the first locking block or the first locking slot is set as a slope, so that when overloaded, the first linkage shaft 21 and the transmission sleeve 3 can be separated under the action of the slope, thereby avoiding overload damage.

[0073] In some embodiments of the present invention, such as Figure 3 As shown, the end of the sleeve 1 is provided with a mounting port 10 for accommodating fasteners, and a magnetic suction element 11 is provided inside the mounting port 10.

[0074] Furthermore, the mounting port 10 has a hexagonal cross-section that matches the fastener, and the end of the mounting port 10 is open, allowing the fastener to be inserted into the mounting port 10 from the open end.

[0075] The magnetic chuck 11 is a magnet, which can magnetically attract the fastener to ensure that the fastener does not come off the mounting opening 10.

[0076] In some embodiments of the present invention, such as Figure 3 As shown, the magnetic suction member 11 is slidably disposed in the mounting port 10 and the magnetic suction member 11 can slide along the axial direction of the sleeve 1. A first elastic member 12 is connected between the magnetic suction member 11 and the sleeve 1.

[0077] Furthermore, the first elastic element 12 is a spring. During the tightening process, the first elastic element 12 can push the magnetic suction element 11 to move away from the mounting port 10, so that a force in the tightening direction can be applied to the fastener to assist in tightening the fastener. During the tightening process, there is no need to drive the sleeve 1 to move axially through external equipment. The sleeve 1 only needs to rotate to tighten the fastener, making the tightening process more controllable.

[0078] The present invention also discloses an installation device, such as Figure 4 As shown, it includes a housing 6 and at least one set of the tightening components described above, the tightening components being disposed on the housing 6.

[0079] Furthermore, the housing 6 is used to connect the movable mechanism, which can drive the installation device to the working position to complete the fastener tightening operation and material loading.

[0080] In some optional embodiments of the present invention, two sets of tightening components are provided, and the sleeve 1, drive shaft 2 and drive sleeve 3 in the two sets of tightening components are arranged in parallel and spaced apart.

[0081] like Figure 1 As shown, the transmission sleeve 3 is provided with a transmission gear 32, and the two sets of transmission gears 32 are connected by an output gear 51. The output end of the second drive device 5 is connected to the output gear 51.

[0082] Furthermore, the first drive device 4 is a telescopic mechanism, specifically a linear cylinder. The telescopic mechanism is connected to the first linkage shaft 21 to drive the first linkage shaft 21 to move axially. The second drive device 5 is a servo motor. The output end of the servo motor is connected to an output gear 51. The output gear 51 meshes with a transmission gear 32 connected to the transmission sleeve 3, so as to simultaneously drive the transmission sleeve 3 in the two sets of tightening assemblies to rotate, so as to synchronously tighten the two sets of fasteners.

[0083] The distance between the two sleeves 1 is the same as the distance between the two fasteners on the hinge. Therefore, by setting two sets of tightening devices, it is possible to tighten the two fasteners on the hinge at the same time, thereby further improving the work efficiency.

[0084] The servo motor can rotate in both the forward and reverse directions, thus enabling it to both tighten and loosen fasteners.

[0085] In some alternative embodiments of the present invention, such as Figure 4 As shown, the tightening assembly is provided with at least three sets. The sleeve 1, drive shaft 2 and drive sleeve 3 in the multiple sets of tightening assemblies are arranged in parallel and spaced apart. The spacing between adjacent sets of sleeve 1 is different from each other.

[0086] like Figure 1 As shown, the transmission sleeve 3 is provided with a transmission gear 32, and two adjacent sets of transmission gears 32 are connected by an output gear 51. The output end of the second drive device 5 is connected to one of the output gears 51.

[0087] The multiple transmission sleeves 3 are driven by the output gear 51, so the multiple transmission sleeves 3 can rotate synchronously.

[0088] Furthermore, the three sets of tightening components are arranged side by side, and the spacing between two adjacent sets of sleeves 1 is different, so it can accommodate two different sizes of hinges for installation.

[0089] Optionally, the three tightening components are arranged in a triangular shape.

[0090] Optionally, the tightening assembly can be set to more than three sets to accommodate the installation of more hinges of different sizes, or to install multiple hinges at the same time, saving tightening / loosening time.

[0091] The second linkage shaft 22 is also provided with a third rotation limiting part 222. The second rotation limiting part 221 and the third rotation limiting part 222 are respectively provided at both ends of the second linkage shaft 22. The cross section of the third rotation limiting part 222 is square or polygonal. The third rotation limiting part 222 is inserted into the sleeve 1 to restrict the relative rotation between the sleeve 1 and the sleeve 1. The sleeve 1 and the third rotation limiting part 222 are connected by a pin arranged radially to restrict the sleeve 1 and the third rotation limiting part 222 from moving axially.

[0092] Among them, different sleeves 1 can be used to tighten fasteners of different specifications.

[0093] Optionally, the distance or torque between two adjacent sets of tightening components can be changed by altering the type of the output gear 51 between adjacent tightening components. Alternatively, a reversing gear can be added to allow two adjacent sets of tightening components to rotate in different directions.

[0094] In some embodiments of the present invention, such as Figure 4 As shown, it also includes a gripping mechanism 7 for gripping the hinge. The gripping mechanism 7 includes a cylinder 71 and an electromagnetic suction head 72. The cylinder 71 is mounted on the housing 6, and the electromagnetic suction head 72 is connected to the cylinder 71.

[0095] Furthermore, such as Figure 4 As shown, the gripping mechanism 7 is located between the two sets of tightening components. The electromagnetic suction head 72 can be moved by the cylinder 71 so that the electromagnetic suction head 72 can contact and attract the hinge. When the hinge is moved to the installation position close to the car door, the cylinder 71 can adjust the position of the hinge and reduce the impact of the hinge contacting the car door, avoiding hard collision between the hinge and the car door, thus protecting the car door and the hinge.

[0096] The electromagnetic suction head 72 is used to attract the middle part of the hinge, and the two ends of the hinge are used to install fasteners. Therefore, the hinge can be gripped by the gripping mechanism 7. At the same time, the two sets of tightening components set on both sides of the gripping mechanism 7 can be aligned with the position of the fasteners installed on the hinge. Therefore, there is no need to readjust the position of the tightening components when installing the hinge, so as to improve the efficiency of the operation.

[0097] In some embodiments of the present invention, such as Figure 5 As shown, it also includes a welding torch 8, which is mounted on the housing 6. The welding torch 8 enables welding operations, thereby reducing the health impact of the welding process on workers.

[0098] The present invention also discloses an installation system, such as Figure 6As shown, it includes a robotic arm 91, a clamping mechanism 92 for clamping the car door, a visual positioning system for positioning the car door, and the aforementioned mounting device. The robotic arm 91 is fixedly connected to the housing 6, and the visual positioning system is communicatively connected to the robotic arm 91.

[0099] Furthermore, the visual positioning system includes multiple cameras, which can locate the installation position on the door to guide the robotic arm 91 to move the installation device to the installation position to install the hinge and complete the subsequent welding process, thereby increasing the degree of automation and improving work efficiency.

[0100] In some embodiments of the present invention, such as Figure 7 As shown, it also includes a fastener conveying assembly 93, which includes a vibratory feeder 931, a sorting turntable 932, and a third drive device 933. The third drive device 933 is connected to the sorting turntable 932 and is used to drive the sorting turntable 932 to rotate. The sorting turntable 932 is located at the output end of the vibratory feeder 931, and the sorting turntable 932 is provided with at least one placement port 934 for accommodating fasteners.

[0101] Furthermore, the vibratory feeder 931 is used to output disordered fasteners in a side-by-side sorting manner from its output end. The output end of the vibratory feeder 931 has a feeding track 935 for sorting the fasteners, and a sorting turntable 932 is disposed at the outlet of the feeding track 935. A third drive unit 933 is used to drive the sorting turntable 932 to rotate. The sorting turntable 932 has placement openings 934, and multiple placement openings 934 can be provided.

[0102] Generally, there are two placement ports 934, and the distance between the two placement ports 934 is the same as the distance between the sleeves 1 in the two sets of tightening assemblies. When receiving fasteners, the sorting turntable 932 is driven to rotate by the third drive device 933, so that the placement port 934 moves to the outlet of the feeding track 935, so that the fasteners can be conveyed into the placement port 934. After both placement ports 934 are filled with fasteners, the third drive device 933 drives the sorting turntable 932 to rotate to a preset position, so that the subsequent tightening assembly can fill and grab the fasteners in the placement port 934.

[0103] The sorting turntable 932 is equipped with multiple photoelectric sensors 936. These sensors detect whether fasteners in the feeding track 935 have been delivered to the correct position and whether fasteners are already in the placement opening 934. If fasteners have been delivered to the correct position, the third drive device 933 controls the sorting turntable 932 to rotate to the receiving position. If fasteners have not been delivered to the correct position, the third drive device 933 stops operating. Furthermore, if fasteners are detected in both placement openings 934, the third drive device 933 drives the sorting turntable 932 to rotate to a preset position for subsequent fastener gripping.

[0104] In addition, the installation system also includes a hinge conveying assembly 94, which is used to arrange multiple hinges so that the gripping mechanism 7 in the installation device can grip the hinges.

[0105] The above description is merely the principle and preferred embodiment of this application. It should be noted that, for those skilled in the art, several other modifications can be made based on the principle of this application, and these modifications should also be considered within the scope of protection of this application.
