Therefore, they should not be understood as limitations on the present invention.

[0027] The embodiment of the present application provides a nut installation device, including a processing table 1 and a screwing assembly 6. The screwing assembly 6 includes a moving part, a fixed channel 61, a screwing head 68 and a conveying channel 62. The moving part is arranged on the processing table 1. The moving part includes a moving seat 5. The fixed channel 61 is connected to the moving seat 5. The outlet end of the fixed channel 61 is provided with a switch component. The screwing head 68 is movably connected to the moving seat 5 along the axial direction of the fixed channel 61. The screwing head 68 is inserted into the fixed channel 61 and is used to screw the nut. The conveying channel 62 is connected to the fixed channel 61 and is used to feed the nut into the fixed channel 61.

[0028] The processing table 1 is used to place the equipment to be processed.

[0029] The movable base 5 can move in space, so that the fixed channel 61 provided on the movable base 5 can move in space.

[0030] The switch component is used to control the opening and closing of the fixed channel 61 .

[0031] The conveying channel 62 can be connected to a point between the two ends of the fixed channel 61, and the twisting head 68 passes through the connection point between the conveying channel 62 and the fixed channel 61 during the travel of the fixed channel 61, that is, the twisting head 68 can be located on both sides of the connection point between the conveying channel 62 and the fixed channel 61 respectively.

[0032] During operation, the movable base 5 first moves to the designated position. Simultaneously, the conveying channel 62 feeds the nut into the fixed channel 61. The screwing head 68 then moves toward the switch component, where it contacts the nut, pushing it along. The switch component then opens, and the screwing head 68, carrying the nut, moves to the screw where the nut is to be installed, aligning the nut with the screw. The screwing head 68 rotates, tightening the nut onto the screw. After installation, the screwing head 68 returns to its original position, the switch component closes, and the conveying channel 62 again feeds the nut into the fixed channel 61, repeating the cycle.

[0033] Compared with the traditional installation method, multiple nuts can be buffered in the conveying channel 62, eliminating the need to take out the nuts multiple times, thereby improving installation efficiency.

[0034] When the nut is accommodated in the fixing channel 61, the nut can be quickly positioned before installation by aligning the fixing channel 61 with the installation position of the nut, thereby reducing the risk of the nut being offset during installation and improving installation efficiency.

[0035] The connection point between the delivery channel 62 and the fixing channel 61 may be located on the side wall of the fixing channel 61 . Meanwhile, the cross-sectional area of ​​the fixing channel 61 may be set to be able to accommodate only one nut.

[0036] The screwing head 68 can be a hollow tubular structure, with the internal cross-sectional shape of the screwing head 68 adapted to the shape of the nut. A magnetic body 69 is provided inside the screwing head 68 to attract the nut. A spring is provided between the magnetic body 69 and the screwing head 68. When the screwing head 68 moves toward the nut, the nut can enter the screwing head 68. At the same time, the magnetic body 69 can attract the nut, reducing the risk of the nut being dislodged from the screwing cavity. The interior of the screwing head 68 is hollow, so that when the nut is turned, the screw installed in the nut can enter the screwing head 68, thereby allowing the nut to be fully tightened.

[0037] The magnetic body 69 may be provided with a guide shaft 610. When the magnetic body 69 contacts the nut, the guide shaft 610 is inserted into the nut, which can adjust the posture and position of the nut, thereby facilitating the alignment of the nut with the screw.

[0038] In some embodiments, the twisting assembly 6 also includes a floating seat 66, which is movably connected to the movable seat 5 along the axial direction of the fixed channel 61. A first elastic member 65 is provided between the floating seat 66 and the movable seat 5, and the twisting head 68 is connected to the floating seat 66.

[0039] The first elastic member 65 can be a spring. The floating seat 66 cooperates with the first elastic member 65 to facilitate the screwing head 68 to reset after completing screwing the nut.

[0040] In some embodiments, the screwing assembly 6 further includes a motor 67 , and an output end of the motor 67 is connected to a screwing head 68 .

[0041] In the embodiment where the screwing assembly 6 includes a floating seat 66 , the motor 67 may be disposed on the floating seat 66 .

[0042] When the motor 67 rotates, it can drive the screwing head 68 to rotate, so that the screwing head 68 can screw the nut.

[0043] In some embodiments, the switch component includes two abutting portions 63, which are arranged opposite to each other. The two abutting portions 63 are rotatably connected to the fixed channel 61, and a second elastic member 64 is arranged between the abutting portions 63 and the fixed channel 61. The second elastic member 64 is used to provide an elastic force that causes the two abutting portions 63 to abut against each other.

[0044] The second elastic member 64 may be a torsion spring.

[0045] Under the action of the second elastic member 64 , the two abutting portions 63 are in an abutting state. At this time, the outlet end of the fixing channel 61 is closed by the two abutting portions 63 , and the nut will not fall out after entering the fixing channel 61 .

[0046] When the twisting head 68 moves toward the switch component, the twisting head 68 can push the two abutting portions 63 to separate, thereby allowing the twisting head 68 to extend from the fixing channel 61 .

[0047] In some embodiments, the moving part also includes a first slide rail 2, a second slide rail 3 and a third slide rail 4. The first slide rail 2 is arranged on the processing table 1, the second slide rail 3 is slidably connected to the first slide rail 2, the third slide rail 4 is slidably connected to the second slide rail 3, and the moving seat 5 is slidably connected to the third slide rail 4. The extension directions of the first slide rail 2, the second slide rail 3 and the third slide rail 4 are perpendicular to each other.

[0048] Under the action of the first slide rail 2 , the second slide rail 3 and the third slide rail 4 , the movable seat 5 can move in space to adjust the position of the fixed channel 61 .

[0049] In some embodiments, a feeding assembly 7 is further included, and the feeding assembly 7 includes a screening component, and the screening component includes a screening channel, a pushing portion, and a discharge channel 75. The screening channel includes a first channel 71 and a second channel 72, and the middle parts of the first channel 71 and the second channel 72 are connected. The pushing portion is accommodated in the second channel 72 and is movably connected to the second channel 72 along the axial direction of the second channel 72, and is used to push the nut to move toward the outlet end of the second channel 72. The discharge channel 75 includes a first diversion channel 76 and a second diversion channel 77, and the discharge channel 75 is movably connected to the second channel 72 so that the first diversion channel 76 and the second diversion channel 77 are selectively connected to the outlet end of the second channel 72, and the first diversion channel 76 is connected to the conveying channel 62.

[0050] The pushing portion is used to push the nut to move toward the outlet end of the second channel 72 , and the first channel 71 is used to send the nut into the second channel 72 .

[0051] The middle of the second channel 72 refers to a position between both ends of the second channel 72 .

[0052] The inlet ends of the first diversion channel 76 and the second diversion channel 77 can face the outlet end of the second channel 72, so that when the discharge channel 75 moves, the first diversion channel 76 and the second diversion channel 77 can be selectively connected to the outlet of the second channel 72.

[0053] The second diverter channel 77 can be connected to the collection chamber, that is, when the nut is in the second channel 72, it can be inspected. If the nut is qualified, the inlet of the first diverter channel 76 can be aligned with the outlet of the second channel 72, so that the nut can be fed into the delivery channel 62 through the first diverter channel 76. If the nut is unqualified, the inlet of the second diverter channel 77 can be aligned with the outlet of the second channel 72, so that the unqualified nut can enter the collection chamber.

[0054] In some embodiments, a detection component 73 is further included, and the detection component 73 is disposed in the second channel 72 .

[0055] The detection component 73 is used to detect the nut to determine whether the nut is qualified. For example, the detection component 73 may include a contact head, and the second channel 72 includes a placement surface for supporting the nut. The contact head is movably connected to the second channel 72 along the normal of the placement surface. By fixing the starting moving position of the contact head, when the contact head moves to abut against the nut set on the placement surface, the movement distance of the contact head can be used to determine whether the thickness of the nut meets the requirements.

[0056] In some embodiments, a gas pumping component 74 is further included. The gas pumping component 74 is used to input gas into the first branch channel 76 to move the nut toward the delivery channel 62.

[0057] The air pump component 74 can be selected from existing products. Its structure and working principle are well known to those skilled in the art and will not be described in detail here.

[0058] By inputting gas into the first branch channel 76, the nut can be moved into the delivery channel 62. The first branch channel 76 and the delivery channel 62 can be connected through a hose.

[0059] In some embodiments, the air pumping component 74 is disposed in the second channel 72 , and the first diversion channel 76 includes an air pumping station. At the air pumping station, the outlet of the air pumping component 74 and the inlet of the first diversion channel 76 are disposed opposite to each other.

[0060] The air pumping component 74 is arranged in the second channel 72, so that the air pumping component 74 and the first diversion channel 76 can be separated, so that the pushing part can push the nut into the first diversion channel 76. When the nut is accommodated in the first diversion channel 76, the first diversion channel 76 is moved to the air pumping station. At this time, the outlet of the air pumping component 74 and the inlet of the first diversion channel 76 are arranged relative to each other, and the gas can enter it from the inlet of the first diversion channel 76 to drive the nut to move.

[0061] In some embodiments, the feeding assembly 7 further includes a centrifugal vibration screening disc, and the discharge port of the centrifugal vibration screening disc is connected to the first channel 71 .
