[0002] The upper and lower rings are key fixings of the RF device, and they need to be screwed on the cylindrical surfaces all around. The early assembly method relied on manual operation. Due to limited space, manual screw locking is difficult, and a maximum of 96 screws need to be screwed on the cylindrical surfaces all around, resulting in a long manual locking time. During the screw locking process, the manual operation does not monitor parameters such as locking torque, locking height, and number of locking circles, which often leads to defects that affect performance, such as the loosening and falling of screws of key fixings, and the scrapping of screws due to excessive torque. Utility Model Content

[0039] The utility model is now described in further detail in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, so they only show the components related to the utility model, and the directions and references (for example, up, down, left, right, etc.) can only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not adopted in a restrictive sense, and the scope of the subject matter claimed is limited only by the attached claims and their equivalents.

[0040] like Figure 1 and Figure 2 As shown, an intelligent locking mechanism for cylindrical screws around a complex and narrow space is used to screw a fixture assembly 1. The fixture assembly 1 includes a fixture body 101 and a support seat 102 for supporting the fixture body 101. The center of the support seat 102 is provided with a slot for the fixture body 101 to be inserted, and the two are positioned by pin insertion. The fixture body 101 is approximately cylindrical and has a locking surface along the circumferential direction for the intelligent locking mechanism to perform the locking operation. The locking surface includes a first locking surface 1011 and a second locking surface 1012 arranged opposite to each other. Figure 5 As shown;

[0041] The intelligent locking mechanism includes a platform 8, on which are arranged a conveying line assembly 2, a flip assembly 3, a material shifting assembly 4, a screw locking assembly 5, a displacement assembly 6 and a screw feeding assembly 10:

[0042] The conveyor line assembly 2 is used to convey the fixture assembly 1, and extends along the X-axis direction;

[0043] The flip assembly 3 is located at one end of the conveyor line assembly 2 and docked therewith, and includes a clamping unit for clamping and positioning the fixture assembly 1 from the conveyor line assembly 2 and a rotating unit for driving the fixture assembly 1 clamped by the clamping unit to flip so that the locking surface faces upward;

[0044] The material shifting assembly 4 is used to shift the fixture assembly 1 on the conveyor line assembly 2 to the inside of the flip assembly 3;

[0045] The screw locking component 5 is located above the flip component 3 and is used to screw the locking surface located below it;

[0046] And the displacement component 6 is used to drive the material shifting component 4 and the screw locking component 5 to move in the X-axis, Y-axis and Z-axis directions.

[0047] During operation, first, the conveyor line component 2 conveys the jig component 1 thereon to the position of the flip component 3, and then the material shifting component 4 shifts the jig component 1 into the inside of the clamping unit, the clamping unit clamps the jig component 1 into position, and the rotating unit flips the clamped and positioned jig component 1 so that the locking surface that needs to be screwed faces upward, and then the screw locking component 5 absorbs the screw and moves it to the specified position through the displacement component 6 for screw locking.

[0048] In some examples, the clamping unit includes an upper clamping seat 301, a lower clamping seat 302, and a linear reciprocating drive mechanism 303 located therebetween for driving the upper clamping seat 301 to move closer to or away from the lower clamping seat 302. The linear reciprocating drive mechanism 303 may be, but is not limited to, a cylinder, a nut screw pair, and the like. The fixed end of the linear reciprocating drive mechanism 303 is connected to the lower clamping seat 302, and the output end is connected to the upper clamping seat 301. The upper clamping seat 301 and the lower clamping seat 302 are arranged in parallel and a space is formed therebetween for accommodating the fixture assembly. 1, the upper clamp seat 301 and the lower clamp seat 302 are respectively fitted with the two end surfaces of the fixture component 1 to clamp the fixture component 1 therebetween, and a rubber pad is installed between the upper clamp seat 301 and the fixture component 1; in addition, the lower clamp seat 302 protrudes from the upper clamp seat 301 in the direction of the conveyor line component 2, that is, the extension length of the upper clamp seat 301 in the X-axis direction is less than the extension length of the lower clamp seat 302 in the X-axis direction, thereby avoiding interference with the upper clamp seat 301 during the material shifting process of the material shifting component 4, such as Figure 3 and Figure 4 As shown; in the initial state, the lower clamp seat 302 is in a horizontal state and docked with the conveyor line assembly 2, and a guide slope 3023 is provided at one end of the lower clamp seat 302 close to the conveyor line assembly 2. After the material shifting assembly 4 shifts the fixture assembly 1 on the conveyor line assembly 2 along the guide slope 3023 to the lower clamp seat 302, the output end of the linear reciprocating drive mechanism 303 retracts and drives the upper clamp seat 301 to move downward, thereby clamping the fixture assembly 1.

[0049] In some examples, at least two shifting holes 1021 are formed on the support seat 102, and the shifting holes 1021 are located at the rear end of the fixture assembly 1 along its conveying direction. The material shifting assembly 4 includes at least two shifting rods 401, and the shifting rods 401 correspond to the shifting holes 1021 one by one, and each shifting rod 401 is inserted into its corresponding shifting hole 1021, and the bottom of the shifting rod 401 is a conical structure, such as Figure 2 and Figure 6 As shown; first, the displacement component 6 drives the lever 401 to move to the position of the lever hole 1021, and moves down to insert into the lever hole 1021, and then the displacement component 6 drives the lever 401 to move along the X-axis direction to shift the fixture component 1 to the inside of the flip component 3;

[0050] In some examples, the support seat 102 is provided with at least two positioning holes 1022, and the number of the positioning holes 1022 can be but is not limited to two, three or four. When the number is two, the two are diagonally distributed. At least two positioning pins 304 are provided on the lower clamping seat 302 for lifting. The head of the positioning pin 304 is a conical structure. The positioning pins 304 correspond to the positioning holes 1022 one by one and each positioning pin 304 is inserted into the corresponding positioning hole 1022. Figure 4 As shown; when the material shifting component 4 shifts the jig component 1 to the specified position inside the flipping component 3, the lifting mechanism drives the positioning pin 304 to move up and insert it into the positioning hole 1022 to achieve plug-in positioning. On the one hand, the cooperation between the positioning pin 304 and the positioning hole 1022 can improve the positioning accuracy of the jig component 1. On the other hand, when the jig component 1 is flipped over for screw locking, the positioning pin 304 can hang the jig component 1, thereby improving the clamping effect of the jig component 1 and avoiding the jig component 1 from being unstable under the action of the screw locking component 5.

[0051] In some examples, the lower clamping seat 302 has protruding slide rails 3021 on both sides along the Y-axis direction for the support seat 102 to slide, and each slide rail 3021 extends along the X-axis direction. A recessed area is formed between the two slide rails 3021, and the positioning pin 304 is installed in the recessed area; after the material shifting assembly 4 shifts the fixture assembly 1 to the flipping assembly 3, the support seat 102 overlaps the two slide rails 3021 and slides along the extension direction of the slide rails 3021. The recessed area and the support seat 102 do not contact each other, thereby reducing the friction between the support seat 102 and the lower clamping seat 302.

[0052] In some examples, a plurality of rollers 305 are installed on the sides of the two slide rails 3021 that are close to each other, and the axes of the rollers 305 are perpendicular to the sliding direction of the jig assembly 1. The rollers 305 are supported under the jig assembly 1 to further reduce the friction between them and the lower clamping seat 302.

[0053] In some examples, the two sides of the two slide rails 3021 that are away from each other both protrude upward to form a limiting portion 3022 , and the support seat 102 is located between the two limiting portions 3022 . The two limiting portions 3022 enclose a sliding space for the support seat 102 to slide.

[0054] In some examples, the displacement assembly 6 includes a gantry 9 arranged on a table 8, and an X-axis displacement unit 601 is installed on the gantry 9. The output end of the X-axis displacement unit 601 is connected to the Y-axis displacement unit 602, and the output end of the Y-axis displacement unit 602 is connected to the first Z-axis displacement unit 603 and the second Z-axis displacement unit 604. The output end of the first Z-axis displacement unit 603 is connected to the material shifting assembly 4, and the output end of the second Z-axis displacement unit 604 is connected to the screw locking assembly 5. The X-axis displacement unit 601, the Y-axis displacement unit 602, the first Z-axis displacement unit 603 and the second Z-axis displacement unit 604 can be but are not limited to linear modules, cylinders or screw nut mechanisms, etc. The X-axis displacement unit 601, the Y-axis displacement unit 602 and the first Z-axis displacement unit 603 can drive the material shifting assembly 4 to move in three-dimensional directions, and the X-axis displacement unit 601, the Y-axis displacement unit 602 and the second Z-axis displacement unit 604 can drive the screw locking assembly 5 to move in three-dimensional directions.

[0055] In some examples, the output end of the Y-axis displacement unit 602 is connected to a substrate 605, a first Z-axis displacement unit 603 and a second Z-axis displacement unit 604 are installed on both sides of the substrate 605, and an upper visual component 7 is installed on the substrate 605. When the flip component 3 clamps the fixture component 1 into position and flips it, the upper visual component 7 takes a photo to position it, and then the screw locking component 5 absorbs the screw to perform the locking operation.

[0056] In some examples, the rotating unit includes a rotating drive mechanism 306, which is a servo motor. The output end of the servo motor is connected to the lower clamping seat 302 and its rotation axis is parallel to the X-axis. The servo motor is started to drive the clamping unit and the fixture assembly 1 clamped therein to rotate around the X-axis.

[0057] Working principle:

[0058] 1) The conveyor assembly 2 conveys the fixture assembly 1 thereon to the position of the flip assembly 3, and then the displacement assembly 6 drives the lever 401 to insert into the lever hole 1021 and drives the fixture assembly 1 to move along the X-axis direction to the specified position of the lower clamping seat 302;

[0059] 2) The positioning pin 304 moves upward and is inserted into the positioning hole 1022 to achieve plug-in positioning, and the output end of the linear reciprocating drive mechanism 303 retracts to drive the upper clamping seat 301 to move downward, thereby clamping the fixture assembly 1;

[0060] 3) The rotating unit turns the fixture assembly 1 90° to the left (the “left” here is relative to Figure 1 For example, the first locking surface 1011 faces upward;

[0061] 4) After the flipping is completed, the upper visual component 7 takes a photo of the fixture component 1 for positioning;

[0062] 5) The intelligent electric screwdriver assembly on the screw locking assembly 5 removes the screws from the screw feeding assembly 10;

[0063] 6) After the screw is sucked, the displacement component 6 drives the screw locking component 5 to move to the specified position to screw the fixture component 1 (the screw locking has the function of judging the number of turns / torque / angle / time and feedback);

[0064] 7) After the first locking surface 1011 is screwed, the rotating unit turns the fixture assembly 1 180° to the right (the "right" here is relative to Figure 1 For example, the second locking surface 1012 faces upward;

[0065] 8) After the flipping is completed, the upper visual component 7 takes a photo of the fixture component 1 for positioning;

[0066] 9) The intelligent electric screwdriver assembly on the screw locking assembly 5 removes the screws from the screw feeding assembly 10;

[0067] 10) After the screw is sucked, the displacement component 6 drives the screw locking component 5 to move to the specified position to screw the fixture component 1 (the screw locking has the function of judging the number of turns / torque / angle / time feedback);

[0068] 11) After the second locking surface 1012 is locked, the rotating unit flips the fixture assembly 1 back to its original position, and then the material shifting assembly 4 shifts the fixture assembly 1 onto the conveyor line assembly 2, and the fixture assembly 1 flows to the next station through the conveyor line assembly 2.
