[0018] A method for replacing the positioning plate fixture in the intelligent assembly of a domain controller includes the following installation steps:

[0019] S1. The moving chain rotates through its own drive, further causing the moving plate to drive the cylinder to move. At this time, the connecting block moves and deviates from the screw locking robot.

[0020] S2. Insert the positioning plate from the open end of the positioning groove and push the positioning plate deep into the positioning groove. At this time, the pin rod of the positioning mechanism is inserted into the limiting groove of the positioning plate under the action of the connecting spring. At this time, the positioning plate is fixed inside the fixture body, and the installation of the positioning plate and the fixture body is completed at this time.

[0021] S3. Move the fixture body by the handle, align the connection slot with the plug board and the connection column with the connection hole, and then connect the fixture body with the connection block. At this time, the plug board is inserted into the connection slot, the connection column is inserted into the connection hole, and further the triangular pin is inserted into the triangular groove, making the end of the plug board in an expanded state, so that the plug board is more tightly connected to the connection slot. The connection column is inserted into the connection hole and clamped and fixed by the clamping arm of the limiting mechanism. At this time, the fixation between the fixture body and the moving mechanism is completed;

[0022] S4. The moving chain is driven to reset itself, so that the fixture body moves under the screw locking robot. At this time, the screw locking robot can complete the screw locking work;

[0023] The following are the disassembly steps:

[0024] S1. The moving chain rotates by its own drive, and further the moving plate drives the cylinder to move. At this time, the connection block drives the fixture body to move away from the screw locking robot;

[0025] S2. Move the wrench. At this time, one end of the wrench abuts against the side of the connection block and the other end tilts outwards, driving the pull rod to move outside the connection block. At this time, the connecting rod drives the clamping arm to rotate around the positioning rod, and further makes the clamping arm away from the connection column. At this time, the plane of the wrench abuts against the side of the connection block, separating the clamping arm from the connection column;

[0026] S3. Horizontally pull the fixture body outwards through the handles on both sides of the fixture body. At this time, the fixture body is separated from the connection block. At this time, the disassembly of the fixture body and the moving mechanism is completed. After disassembly, move the wrench to make the wrench reset to a vertical state;

[0027] S4. Pull the pull sleeves on both sides of the fixture body, so that the pin rod moves out of the limit slot of the positioning plate. At this time, pull the positioning plate, and the positioning plate can be pulled out of the fixture body. At this time, the disassembly of the positioning plate and the fixture body is completed.

[0028] (III) Beneficial effects

[0029] The embodiment of the present invention provides a method and device for replacing the positioning plate fixture in the intelligent assembly of the domain controller. It has the following beneficial effects:

[0030] 1. Insert the positioning plate into the connection slot of the fixture body, and then align the fixture body and insert it into the connection block.

[0031] 2. When replacing, install the positioning plate into the fixture body in advance, reducing the replacement time and further improving the work efficiency.

[0032] 3. When the fixture body is connected to the connection block, the triangular pin is inserted into the triangular groove. At this time, the end of the insertion plate expands, making the fit between the insertion plate and the connection groove tighter. This design makes the connection between the fixture body and the connection block tighter.

[0033] 4.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] Referring to the attached Figure 1-2 , a positioning plate fixture replacement device for intelligent assembly of a domain controller, comprising a fixture body 1, a moving mechanism 2, and a screw locking robot 3. The moving mechanism 2 drives the fixture body 1 to move under the screw locking robot 3 for screw locking, and the moving mechanism 2 drives the fixture body 1 to move to one side of the screw locking robot 3 to facilitate the replacement of the fixture body 1;

[0046] Referring to the attached Figures 3-5 , a connecting groove 12 is provided at the bottom of the fixture body 1. The moving mechanism 2 includes a connecting block 24. An inserting plate 241 adapted to the connecting groove 12 is provided at the bottom of the connecting block 24. A triangular pin 13 is provided in the connecting groove 12. A triangular groove 242 adapted to the triangular pin 13 is provided at the end of the inserting plate 241. The triangular pin 13 is in interference fit with the triangular groove 242. When the fixture body 1 is connected to the connecting block 24, the inserting plate 241 is inserted into the connecting groove 12. At this time, the triangular pin 13 is inserted into the triangular groove 242, causing the end of the inserting plate 241 to expand, making the fit between the inserting plate 241 and the connecting groove 12 tighter, that is, increasing the connection strength between the fixture body 1 and the connecting block 24.

[0047] Referring to the attached Figures 6-7 , a connecting column 14 is provided on one side of the fixture body 1. An annular groove 141 adapted to the clamping arm 2441 is provided on the connecting column 14. The end of the connecting column 14 away from the fixture body 1 is a tapered column 142 with a gradually decreasing diameter. When the connecting column 14 is inserted into the connecting hole 243, the tapered column 142 with a gradually decreasing diameter will first push the two clamping arms 2441 to expand outwards. When the annular groove 141 moves into the two clamping arms 2441, at this time, under the action of the supporting spring 2442, the two clamping arms 2441 approach each other and stick into the annular groove 141. At this time, the connecting column 14 is fixed by the two clamping arms 2441. The width of the annular groove 141 is adapted to the width of the clamping arm 2441. After the connecting column 14 is fixed by the clamping arm 2441, it cannot move back and forth in the annular groove 141. A cavity adapted to the limiting mechanism is provided in the connecting block 24. The width of this cavity is adapted to the width of the clamping arm 2441. At this time, the cavity in the connecting block 24 will limit the clamping arm 2441, making the clamping arm 2441 unable to move back and forth, further limiting the connecting column 14, and fixing the fixture body 1 and the connecting block 24 so that they cannot be pulled apart back and forth.

[0048] The connecting block 24 is internally provided with a connecting hole 243 that matches the connecting column 14. A limiting mechanism for clamping the connecting column 14 is arranged inside the connecting block 24. The limiting mechanism includes symmetrically arranged clamping arms 2441. A support spring 2442 is arranged between the two clamping arms 2441. A positioning rod 2443 is rotatably connected inside the clamping arm 2441. A connecting rod 2444 is rotatably connected to the clamping arm 2441. One end of the connecting rod 2444 away from the clamping arm 2441 is rotatably connected to a pull rod 2445. One end of the pull rod 2445 extending out of the connecting block 24 is rotatably connected to a wrench 2446. By moving the wrench 2446, one end of the wrench 2446 abuts against the side surface of the connecting block 24. At this time, the wrench 2446 will drive the pull rod 2445 to move outward from the connecting block 24, further driving the connecting rod 2444 to drive the clamping arm 2441 to move. At this time, the clamping arm 2441 rotates around the positioning rod 2443, further causing the clamping arm 2441 to move away from the connecting column 14. At this time, the clamping arm 2441 no longer limits the connecting column 14. At this time, the fixture body 1 is horizontally pulled, so that the fixture body 1 is separated from the connecting block 24. At this time, the separation and disassembly between the fixture body 1 and the moving mechanism 2 are completed.

[0049] Refer to the appendix Figure 8 One end of the wrench 2446 is provided with an arc surface 2446a and a flat surface 2446b. A rotating shaft 2446c is arranged in the middle of the wrench 2446. The rotating shaft 2446c is inserted into the pull rod 2445 and the two are rotatably connected. A connecting plate 2446d is arranged on the side of the wrench 2446 away from the arc surface 2446a. The thickness of the connecting plate 2446d is smaller than that of the wrench 2446 and is arranged away from the connecting block 24. When the wrench 2446 is moved, the rotating shaft 2446c of the wrench 2446 rotates in the pull rod 2445, and the arc surface 2446a end of the wrench 2446 abuts against the side wall of the connecting block 24. By continuing to move the wrench 2446, the wrench 2446 drives the pull rod 2445 to move outward from the connecting block 24. When the flat surface 2446b of the wrench 2446 abuts against the side wall of the connecting block 24 and remains perpendicular, at this time, the pull rod 2445 moves outward from the connecting block 24, and the clamping arm 2441 moves away from the connecting column 14.

[0050] Refer to the appendix Figures 3-4 Handles 16 are arranged on both sides of the fixture body 1 to facilitate the movement of the fixture body 1. A positioning groove 11 that matches the positioning plate 17 is arranged inside the fixture body 1 to facilitate the installation of the positioning plate 17. Positioning holes for matching the fixing screws of the screw locking robot 3 are arranged on the positioning plate 17 to facilitate the screw locking of the screw locking robot 3. Positioning mechanisms 15 for fixing the positioning plate 17 are arranged on both sides of the fixture body 1 to facilitate the fixing of the positioning plate 17 and prevent the positioning plate 17 from shifting, affecting the screw locking.

[0051] Refer to the appendix Figure 9, the positioning mechanism 15 includes a pull sleeve 151, a pin rod 152, and a connecting spring 153. One end of the pin rod 152 is connected inside the pull sleeve 151, and the other end extends into the positioning groove 11 of the fixture body 1. Limiting grooves for mating with the pin rod 152 are provided on both sides of the positioning plate 17. One end of the connecting spring 153 is connected inside the pull sleeve 151, and the other end is connected to the side wall of the fixture body 1.

[0052] In this embodiment, a slope is provided on one side of the pin rod 152 facing the inlet side of the positioning groove 11. When the positioning plate 17 is installed into the positioning groove 11, the slope will be squeezed, causing the pin rod 152 to move outward, which will not hinder the installation of the positioning plate 17, making the installation convenient and fast.

[0053] In this embodiment, the moving mechanism 2 further includes a moving chain 21. A moving plate 22 is provided on the moving chain 21. A cylinder 23 is provided on the moving plate 22. The output end of the cylinder 23 is connected to the connecting block 24. The moving chain 21 drives the moving plate 22 to move through its own drive, further improving the movement of the cylinder 23 driving the connecting block 24.

[0054] A method for replacing the positioning plate fixture in the intelligent assembly of a domain controller includes the following installation steps:

[0055] S1. The moving chain 21 rotates through its own drive, further causing the moving plate 22 to drive the cylinder 23 to move. At this time, the connecting block 24 moves and deviates from the screw locking robot 3;

[0056] S2. Insert the positioning plate 17 from the open end of the positioning groove 11 and push the positioning plate 17 deep into the positioning groove 11.

At this time, the insertion plate 241 is inserted into the connecting groove 12, the connecting column 14 is inserted into the connecting hole 243, further causing the triangular pin 13 to be inserted into the triangular groove 242, making the end of the insertion plate 241 in an expanded state, making the connection between the insertion plate 241 and the connecting groove 12 tighter. The connecting column 14 is inserted into the connecting hole 243 and is clamped and fixed by the clamping arm 2441 of the limiting mechanism. At this time, the fixation between the fixture body 1 and the moving mechanism 2 is completed;

[0058] S4. The moving chain 21 resets through its own drive, causing the fixture body 1 to move under the screw locking robot 3. At this time, the screw locking robot 3 can complete the screw locking work;

[0059] During installation, directly insert the positioning plate 17 into the connection slot 12 of the fixture body 1. At this time, the installation of the positioning plate 17 and the fixture body 1 is completed, facilitating the quick installation of different positioning plates 17. Align the fixture body 1 and insert it into the connection block 24.

At this time, the connection between the fixture body 1 and the moving mechanism 2 is completed, facilitating the quick installation of different fixture bodies 1. The installation is simple and fast, greatly improving the installation speed.

[0060] The disassembly steps are as follows:

[0061] S1. The moving chain 21 rotates by its own drive, further causing the moving plate 22 to drive the cylinder 23 to move. At this time, the connection block 24 drives the fixture body 1 to move away from the screw locking robot 3.

[0062] S2. Move the wrench 2446. At this time, one end of the wrench 2446 abuts against the side surface of the connection block 24 and the other end tilts outward, driving the pull rod 2445 to move outside the connection block 24. At this time, the connecting rod 2444 drives the clamping arm 2441 to rotate around the positioning rod 2443, further causing the clamping arm 2441 to move away from the connecting column 14. At this time, the plane 2446b of the wrench 2446 abuts against the side surface of the connection block 24, separating the clamping arm 2441 from the connecting column 14.

The moving chain (21) rotates by its own drive, further causing the moving plate (22) to drive the cylinder (23) to move. At this time, the connecting block (24) moves and deviates from the screw locking robot (3); S2. Insert the positioning plate (17) from the open end of the positioning groove (11), and push the positioning plate (17) deep into the positioning groove (11). At this time, the pin rod (152) of the positioning mechanism (15) is inserted into the limiting groove of the positioning plate (17) under the action of the connecting spring (153). At this time, the positioning plate (17) is fixed in the fixture body (1), and the installation of the positioning plate (17) and the fixture body (1) is completed; S3. Move the fixture body (1) by the handle (16), align the connecting groove (12) with the insertion plate (241), align the connecting column (14) with the connecting hole (243), and then connect the fixture body (1) with the connecting block (24). At this time, the insertion plate (241) is inserted into the connecting groove (12), the connecting column (14) is inserted into the connecting hole (243), and further the triangular pin (13) is inserted into the triangular groove (242), so that the end of the insertion plate (241) is in an expanded state, making the connection between the insertion plate (241) and the connecting groove (12) tighter. The connecting column (14) is inserted into the connecting hole (243) and is clamped and fixed by the clamping arm (2441) of the limiting mechanism. At this time, the fixation between the fixture body (1) and the moving mechanism (2) is completed; S4. The moving chain (21) resets by its own drive, causing the fixture body (1) to move below the screw locking robot (3). At this time, the screw locking robot (3) completes the screw locking work; It includes the following disassembly steps: S1. The moving chain (21) rotates by its own drive, further causing the moving plate (22) to drive the cylinder (23) to move. At this time, the connecting block (24) drives the fixture body (1) to move and deviates from the screw locking robot (3); S2. Move the wrench (2446). At this time, one end of the wrench (2446) abuts against the side surface of the connecting block (24) and the other end warps outwards, driving the pull rod (2445) to move outside the connecting block (24). At this time, the connecting rod (2444) drives the clamping arm (2441) to rotate around the positioning rod (2443), further causing the clamping arm (2441) to move away from the connecting column (14). At this time, the plane (2446b) of the wrench (2446) abuts against the side surface of the connecting block (24), separating the clamping arm (2441) from the connecting column (14); S3. Horizontally pull the fixture body (1) outward through the handles (16) on both sides of the fixture body (1). At this time, the fixture body (1) is separated from the connecting block (24), and the disassembly of the fixture body (1) and the moving mechanism (2) is completed. After disassembly, toggle the wrench (2446) to reset the wrench (2446) to a vertical state; S4. Pull the pull sleeves (151) on both sides of the fixture body (1) to move the pin rod (152) out of the limit groove of the positioning plate (17). At this time, pull the positioning plate (17) to pull the positioning plate (17) out of the fixture body (1), and the disassembly of the positioning plate (17) and the fixture body (1) is completed.
