Description

Technical Field

[0001] This invention relates to the field of diesel generator assembly technology, and more specifically, to an automatic assembly equipment and method for diesel generator set parts. Background Technology

[0002] In the prior art, such as the diesel generator set enclosure disclosed in the authorization announcement number CN219587655U, the enclosure has multiple doors installed on the side, such as maintenance doors. The edges of the doors are connected to the enclosure by two hinges to achieve the opening and closing of the doors.

[0003] In the assembly process of existing diesel generator set enclosure doors (such as maintenance doors), the connection between the door and the enclosure mainly relies on hinges and bolts. Currently, the industry mostly uses manual assembly, which has the following significant drawbacks: 1. Cumbersome and inefficient operation: Manual labor is required to first move the door panel to the side of the cabinet, manually adjust the door panel's posture to align with the hinge installation position, and then tighten the bolts one by one to fix it. The assembly of a single door often requires 2-3 people to work together, which is time-consuming and difficult to adapt to the needs of large-scale production.

[0004] 2. Poor assembly precision: When manually tightening hinge bolts, deviations are prone to occur, which can easily lead to bolt tilting, stripping, or uneven force on the hinge, affecting the installation quality of the door panel.

[0005] 3. High labor intensity and insufficient safety: The door panels are mostly made of metal and are quite heavy. They are prone to being bumped or falling during manual handling and flipping, posing a safety hazard. At the same time, the repetitive labor of repeatedly tightening bolts can easily lead to operator fatigue.

[0006] Although some companies have tried to introduce simple auxiliary tools, they still need to manually position and tighten bolts. Therefore, this solution provides a device that can automatically grab, accurately align and automatically tighten bolts on door panels. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an automatic assembly equipment and method for diesel generator set parts, which solves the problem of low assembly efficiency of diesel generator set door.

[0008] To achieve the above objectives, the present invention provides the following technical solution: This invention provides an automatic assembly device for diesel generator set parts, comprising an upper frame, a middle frame, and a bottom frame. The upper frame is slidably mounted on the middle frame along the Z-axis and is equipped with a flipping device and a tightening device. The middle frame is slidably mounted on the bottom frame along the X-axis and is equipped with a limiting device. The flipping device is slidably mounted on the upper frame along the X-axis and is equipped with a suction cup device on its flipping part.

The third bevel gear and the fourth bevel gear mesh with each other. The third bevel gear is installed on the second spindle, and the fourth bevel gear is connected to one end of a second power shaft. The first power shaft and the second power shaft on either sleeve mounting base rotate in the same direction.

[0011] According to one embodiment of the present invention, a camera is installed on one side of the sleeve mounting base to simultaneously align with the two sleeves connected by the first power shaft and the second power shaft. Both the first power shaft and the second power shaft are segmented, and electromagnetic clutches are provided at the disconnection positions of the first power shaft and the second power shaft.

[0012] According to one embodiment of the present invention, the tightening device includes a U-shaped adjusting frame. The upper and lower ends of the adjusting frame are slidably adapted to the second support beam of the upper frame, and the corresponding sliders are provided with locking devices. Two sleeve mounting seats are aligned and arranged in the U-shaped groove of the adjusting frame along the Z-axis direction. Each sleeve mounting seat is connected to a mounting frame and a guide block. The mounting frame is also connected to a second nut block. The U-shaped groove of the adjusting frame is provided with an adjusting screw threadedly adapted to the second nut block and a guide rod slidably adapted to the guide block.

[0013] According to one embodiment of the present invention, the flipping part of the flipping device includes a flipping column, and two first support beams of the upper frame are slidably connected to rotating supports. Both ends of the flipping column are rotatably mounted on the rotating supports. A torque motor is mounted on any rotating support, and the output end of the torque motor is fixedly connected to one end of the flipping column. A flipping plate is fixedly connected to the flipping column. The flipping plate switches between a vertical state and a horizontal state. A compensation cylinder is mounted above the flipping plate, and the suction cup device is disposed below the flipping plate and fixedly connected to the output end of the compensation cylinder.

[0014] According to one embodiment of the present invention, the suction cup device includes a support plate fixedly connected to the output end of the compensation cylinder, and a plurality of vacuum suction cups are fixedly mounted on the support plate by bolts.

[0015] According to one embodiment of the present invention, the middle frame includes a slide plate, and lifting cylinders are arranged around the slide plate. The output end of the lifting cylinders is fixedly connected to the bottom of the upper frame. The limiting device includes a first limiting component, a second limiting component, and a support platform mounted on the slide plate. One of the first limiting component and the second limiting component is provided on one of the four sides of the support platform. The first limiting component includes a first limiting plate and a first limiting cylinder. The first limiting plate is slidably disposed on the support platform, and the first limiting cylinder drives the first limiting plate to move linearly toward the center of the support platform. The second limiting component includes a second limiting cylinder and a second limiting plate slidably disposed on the support platform. The second limiting cylinder is fixed to the side of the support platform, and its output end drives the second limiting plate to move linearly.

[0016] According to one embodiment of the present invention, a position sensor is also installed on the third support beam of the upper frame. The transmitting end of the position sensor is aligned with the flip plate in the vertical state. The bottom frame includes a base plate and a lead screw motor and a lead screw mounted on the base plate. The output end of the lead screw motor is connected to the lead screw. The slide plate is slidably mounted on the base plate in the X direction. A first nut block adapted to the lead screw thread is fixedly connected to the bottom end of the slide plate. Casters are installed at the bottom end of the base plate, and at least two adjacent casters are self-locking casters.

[0017] This invention also provides an assembly method for an automatic assembly equipment for diesel generator set parts, comprising the following specific steps: S1, installing the door panel on the middle frame and locking the door panel using a limiting device; S2, flipping the device to a horizontal state, grabbing the door panel using a suction cup device, and then flipping the device back to a vertical state to enter a waiting state; S3, manually pushing the equipment close to the housing, then pushing the flipping device to send the door panel into the door frame of the housing, and moving the hinge to press it against the outer wall of the housing; S4, adjusting the height of the two sleeve mounting seats according to the height of the hinge, and then individually adjusting the distance between the first power shaft and the second power shaft in each sleeve mounting seat so that they correspond to the bolt holes on the hinge, inserting bolts into the sleeves and slowly moving the tightening device to insert the bolts in the sleeves into the corresponding bolt holes; S5, starting the servo motor to tighten the bolts.

[0018] In summary, this application includes at least one of the following beneficial technical effects: 1. This equipment is used to assist in the installation of doors. It automatically grabs the door panel with hinges and adjusts the posture of the door panel. Then, it uses the two sleeve mounting seats of the tightening device to automatically tighten the bolts to complete the rapid installation of the door panel. This equipment realizes automatic grabbing, precise alignment and rapid fixing of door panels, reducing the need for manual operation and significantly improving installation efficiency and accuracy.

[0019] 2. In this solution, the position of one of the first or second power shafts connected to the adjusting support is linearly adjusted along the direction of the mounting groove by the cooperation of the fixed support and the sliding adjusting support in the mounting groove of the sleeve mounting seat. This allows for precise adjustment of the relative distance between the two power shafts, adapting to the distance of bolt holes on different hinges. At the same time, the sub-drive shaft and the mother drive shaft in the telescopic assembly are axially sliding and circumferentially fixed. With the cooperation of the sub-drive shaft, the mother drive shaft, the fixed support, and the adjusting support, the two power shafts can have relative displacement along the axial direction when transmitting torque, thus enabling torque transmission when the position changes and improving the adaptability of the tightening device.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example

[0023] like Figure 1 As shown, this is an automatic assembly device for diesel generator set parts provided in Embodiment 1 of the present invention. Embodiment 1 includes an upper frame 1, a middle frame 2, and a bottom frame 3. The upper frame 1 is slidably mounted on the middle frame 2 along the Z-axis direction, and a flipping device 4 and a tightening device 5 are installed on the upper frame 1. The tightening device 5 is slidably mounted on one end of the upper frame 1 along the Y-axis direction. Figure 5As shown, the upper frame 1 is provided with a first support beam 101, a second support beam 102, and a third support beam 103. The first support beam 101 is used to install the tilting device 4, and the second support beam 102 is used to install the tightening device 5. Figure 1 As shown, the flipping device 4 moves along the X-axis, while the tightening device 5 moves along the Y-axis. When the tightening device 5 moves to both sides of the upper frame 1, there is still a gap between the flipping device 4 and the tightening device 5 in the YZ plane to avoid interference between the two.

[0024] Next, as Figure 3 and Figure 4 As shown, in this embodiment, the middle frame 2 is slidably disposed on the bottom frame 3 along the X-axis direction, and the middle frame 2 is provided with a limiting device 6. The door panel 9 is placed on the middle frame 2, and the limiting device 6 can limit the door panel 9. The flipping device 4 is slidably disposed on the upper frame 1 along the X-axis direction, and a suction cup device 7 is installed on the flipping part of the flipping device 4. The limiting device 6 is used to limit the position of the door panel 9 on the suction cup device 7 to ensure that the door panel 9 can be located in the middle position of the suction cup device 7.

[0025] Typically, two hinges are installed side-by-side on the same side of a door panel 9. The traditional method of tightening each hinge individually with a single bolt can lead to misalignment of the remaining three holes on the hinge after the first bolt is installed, requiring manual adjustment. Furthermore, after the first hinge is installed, because the door panel 9 and the hinge are installed vertically, gravity can cause a slight tilt (roughly centered on the first hinge). This slight tilt can result in misalignment of the bolt holes on the second hinge. Therefore, the tightening device 5 in this embodiment has two sleeve mounting seats 502 for aligning the two hinges. A servo motor 508 and a first power shaft 503 and a second power shaft 504 for connecting the sleeves are mounted on the sleeve mounting seats 502. The output end of the servo motor 508 is powered to the first power shaft 503 and the second power shaft 504 respectively through the telescopic component 507. Bolts can be connected to the sleeve mounting seats 502 through the sleeves. In this embodiment, pentagonal bolts or hexagonal bolts can be used. The distance between the first power shaft 503 and the second power shaft 504 can be changed by the deformation of the telescopic component 507, so that the first power shaft 503 and the second power shaft 504 can be adapted to the bolt hole positions on different hinges.

[0026] like Figure 5 and Figure 6As shown, the tightening device 5 includes a U-shaped adjusting frame 501. The upper and lower ends of the adjusting frame 501 are slidably adapted to the second support beam 102 of the upper frame 1, and corresponding sliders are equipped with locking devices 5016. The locking devices 5016 are used to fix the adjusting frame 501 after it slides into place, preventing displacement during assembly. The locking devices 5016 achieve quick locking and unlocking by rotating the handle or pulling the lever, making operation simple and highly reliable. For example... Figure 6 As shown, two sleeve mounting seats 502 are aligned along the Z-axis and positioned in the U-shaped groove of the adjusting frame 501. Each sleeve mounting seat 502 is connected to a mounting frame 5013 and a guide block 5015. A second nut block 5014 is also connected to the mounting frame 5013. The U-shaped groove of the adjusting frame 501 contains an adjusting screw 5011 threadedly connected to the second nut block 5014 and a guide rod 5012 slidably connected to the guide block 5015. In this embodiment, the adjusting frame 501 is provided with two adjusting screws 5011 that are adapted to the two second nut blocks 5014, thereby enabling individual adjustment of the height of each sleeve mounting seat 502. To avoid interference between the upper and lower sleeve mounting seats 502, a servo motor 508 is installed at the ends of the two sleeve mounting seats 502 that are far apart from each other. To achieve automated operation, a controller is also provided in this device, which is connected to the electrical equipment in this invention. For example, the controller and servo motor 508 are connected via wired or wireless means and support bidirectional signal interaction.

[0027] like Figures 6-8 As shown, the sleeve mounting base 502 has a mounting groove. A first power shaft 503 and a second power shaft 504 are connected within the mounting groove via a fixed support 505 and an adjusting support 506. The fixed support 505 is fixed within the mounting groove, and the adjusting support 506 is slidably mounted within it. A sliding block 5061 is connected to one side of the adjusting support 506, and a threaded groove is formed on the sliding block 5061. A guide groove 5021, slidably connected to the sliding block 5061, is formed on the inner wall of one side of the mounting groove. A manual screw 5022, connected to the threaded groove, is also connected within the guide groove 5021. Figure 10As shown, the end of the manual screw 5022 is equipped with a handwheel or wrench interface, which facilitates the operator to rotate the manual screw 5022. The manual screw 5022 is then threadedly connected to the sliding block 5061 to drive the sliding block 5061 to move along the guide groove 5021, thereby changing the position of the adjusting support 506 in the mounting groove and thus changing the distance between the fixed support 505 and the adjusting support 506. The guide groove 5021 adopts a T-shaped or dovetail groove design to ensure that the sliding block 5061 does not shift laterally during movement, improving positioning accuracy and stability. The telescopic assembly 507 includes a sub-drive shaft 5075 and a female drive shaft 5076 that are axially sliding and circumferentially fixed. The sub-drive shaft 5075 is linked to one of the first power shaft 503 and the second power shaft 504, and the female drive shaft 5076 is linked to the other of the first power shaft 503 and the second power shaft 504.

[0028] like Figure 8 As shown, the sub-drive shaft 5075 and the female drive shaft 5076 of the telescopic assembly 507 are circumferentially fixedly connected by a spline or keyway structure, allowing them to freely extend and retract axially to adapt to the dynamic displacement requirements during equipment assembly. Previously, the position of the adjusting support 506 in the mounting slot could be changed by the manual screw 5022, thereby changing the distance between the fixed support 505 and the adjusting support 506. At this time, the relative position between the sub-drive shaft 5075 connected to the fixed support 505 and the female drive shaft 5076 connected to the adjusting support 506 also changed. Since the sub-drive shaft 5075 and the female drive shaft 5076 are splined, it is ensured that the fixed support 505 and the adjusting support 506 can still transmit power to each other when their positions change. The sub-drive shaft 5075 is directly connected to the first power shaft 503 through a coupling or flange, and the female drive shaft 5076 is connected to the second power shaft 504 in a similar manner. In addition, a scale is integrated on the groove of the mounting slot, which makes it easy to determine the distance between the first power shaft 503 and the second power shaft 504 based on the distance between the two bolt holes on the hinge, so that the sleeves and bolts on the two power shafts can be directly aligned with the corresponding bolt holes after installation.

[0029] like Figure 9As shown, the telescopic assembly 507 also includes a first bevel gear 5071, a second bevel gear 5072, and a first spindle 5077 installed in the fixed support 505, and a third bevel gear 5073, a fourth bevel gear 5074, and a second spindle 5078 installed in the adjusting support 506. The first spindle 5077 is rotatably mounted in the fixed support 505, and one end of the first spindle 5077 is fixedly connected to the sub-drive shaft 5075. The first bevel gear 5071 and the second bevel gear 5072 mesh with each other, and the first bevel gear 5071 is mounted on the first spindle. The second bevel gear 5072 is connected to one end of the first power shaft 503 on the sleeve mounting base 5077; the second spindle 5078 is rotatably mounted in the adjusting support 506 and one end of the second spindle 5078 is fixedly connected to the female transmission shaft 5076; the third bevel gear 5073 and the fourth bevel gear 5074 mesh with each other, the third bevel gear 5073 is mounted on the second spindle 5078 and the fourth bevel gear 5074 is connected to one end of the second power shaft 504; the first power shaft 503 and the second power shaft 504 on any sleeve mounting base 502 rotate in the same direction. The telescopic assembly 507 transmits and reverses the power of the first power shaft 503 and the second power shaft 504, which rotate in the same direction, through two sets of bevel gear mechanisms. Within the fixed support 505, the first power shaft 503 drives the second bevel gear 5072, which meshes to cause the first bevel gear 5071 to rotate in the opposite direction, driving the first spindle 5077 and the sub-drive shaft 5075 to output power. Within the adjusting support 506, the second power shaft 504 drives the fourth bevel gear 5074, which meshes to cause the third bevel gear 5073 to rotate in the opposite direction, driving the second spindle 5078 and the main drive shaft 5076 to output power. The sub-drive shaft 5075 and the main drive shaft 5076 adopt a nested structure, maintaining continuous and stable power transmission through the rigid connection between the spindle and the drive shaft when the fixed support 505 and the adjusting support 506 extend or retract relative to each other.

[0030] In this embodiment, a camera 509 is installed on one side of the sleeve mounting base 502 to simultaneously align with the two sleeves connected to the first power shaft 503 and the second power shaft 504. The camera 509 is preferably a CCD camera. It imports characteristic photos of bolt installation abnormalities, such as bolt tilting or misalignment between the bolt and the bolt hole, into the control terminal. The camera 509 continuously takes pictures of the bolts in the two sleeves. The control terminal compares the real-time photos with the characteristic photos and determines whether bolt installation abnormalities have occurred.

[0031] Furthermore, the first power shaft 503 and the second power shaft 504 can be segmented. Electromagnetic clutches 5010 are provided at the disconnected positions of the first power shaft 503 and the second power shaft 504. In this way, the torque transmission of the first power shaft 503 and the second power shaft 504 can be controlled independently through their respective electromagnetic clutches 5010. When the bolt installation is tilted and a withdrawal operation needs to be performed, it is only necessary to keep the electromagnetic clutch 5010 corresponding to the tilted bolt powered so that the power shaft of the servo motor 508 rotates in the opposite direction to remove the tilted bolt from the bolt hole.

[0032] like Figure 2 As shown, the flipping part of the flipping device 4 in this embodiment includes a flipping column 401. Rotating supports 403 are slidably connected to the two first support beams 101 of the upper frame 1. The two ends of the flipping column 401 are rotatably mounted on the rotating supports 403. A torque motor 402 is mounted on any rotating support 403. The output end of the torque motor 402 is fixedly connected to one end of the flipping column 401. A flipping plate 404 is fixedly connected to the flipping column 401. The flipping plate 404 switches between a vertical state and a horizontal state. A compensation cylinder 405 is mounted above the flipping plate 404. A suction cup device 7 is located below the flipping plate 404 and is fixedly connected to the output end of the compensation cylinder 405.

[0033] like Figure 3 and Figure 4 As shown, the middle frame 2 in this embodiment includes a slide plate 201. Lifting cylinders 202 are arranged around the slide plate 201. Guide posts 7033 are provided on the lifting cylinders 202 and slidably connected to the upper frame 1. The output end of the slide plate 201 is fixedly connected to the bottom of the upper frame 1. The limiting device 6 includes a first limiting component 601, a second limiting component 602, and a support platform 603 mounted on the slide plate 201. One of the first limiting component 601 and the second limiting component 602 is provided on each of the four sides of the support platform 603. The first limiting component 601 includes a first limiting plate 6011 and a first limiting cylinder 6012. The first limiting plate 6011 is slidably mounted on the support platform 603. The first limiting cylinder 6012 is fixed to the edge of the support platform 603, and its output end drives the first limiting plate 6011 to move linearly toward the center of the support platform 603. The second limiting assembly 602 includes a second limiting cylinder 6022 and a second limiting plate 6021 slidably mounted on the support platform 603. One end of the second limiting plate 6021 extends to the edge of the support platform 603. The second limiting cylinder 6022 is fixed to the edge of the slide plate 201, and the output end of the second limiting cylinder 6022 is fixedly connected to the bottom of the second limiting plate 6021 to drive the second limiting plate 6021 to move linearly. The suction cup device 7 includes a support plate 701 fixedly connected to the output end of the compensation cylinder 405. Multiple vacuum suction cups 702 are fixedly mounted on the support plate 701 by bolts.

[0034] To ensure the flip plate 404 remains vertical and accurately locates the position to grab the door panel 9, a position sensor 8 is installed on the third support beam 103 of the upper frame 1. The transmitter of the position sensor 8 is aligned with the flip plate 404 in the vertical position, and in this position, the flip plate 404 can accurately grab the door panel 9. Figure 4 As shown, the bottom frame 3 includes a base plate 304 and a lead screw motor 301 and a lead screw 302 mounted on the base plate 304. The output end of the lead screw motor 301 is connected to the lead screw 302. A slide plate 201 is slidably mounted on the base plate 304 in the X direction. A first nut block 303 that is threadedly adapted to the lead screw 302 is fixedly connected to the bottom end of the slide plate 201. Casters 305 are mounted on the bottom end of the base plate 304, and at least two adjacent casters 305 are self-locking casters. Example

[0035] Reference Figure 11 As shown, based on Embodiment 1, Embodiment 2 of the present invention provides an automatic assembly equipment for diesel generator set parts. In order to ensure the stability of the door panel 9 during the assembly process, positioning components 703 are installed at the upper and lower edges of the support plate 701. The positioning components 703 are used to fix the relative position between the equipment and the door panel 9 after the hinges on the door panel 9 are aligned with the bolt holes on the outer wall of the equipment, so as to facilitate the subsequent installation of the door panel 9.

[0036] Specifically, refer to Figure 13 As shown, the positioning assembly 703 includes a suction cup bracket 7031, a pneumatic suction cup 7032, a guide post 7033, and a guide sleeve 7034. Two pneumatic suction cups 7032 are mounted on the suction cup bracket 7031. The guide sleeve 7034 is mounted on the support plate 701. One end of the guide post 7033 is fixedly connected to the suction cup bracket 7031. A limiting groove 70331 is formed on the guide post 7033, and the guide post 7033 slides through the guide sleeve 7034. A locking nut 7035 is on the guide sleeve 7034. The limiting groove 70331 on the guide post 7033 passes precisely through the bottom end of the locking nut 7035, thus forming a circumferential limit on the guide post 7033. By tightening the locking nut 7035, the guide post 7033 can be locked in the guide sleeve 7034.

[0037] Based on the solution provided in Embodiment 2, this Embodiment 2 also provides an assembly method for an automatic assembly equipment for diesel generator set parts, including the following specific steps: S1, place the door panel 9 on the middle frame 2, and lock the door panel 9 through the limiting device 6; S2, refer to Figure 1 As shown, the flipping device 4 grips the door panel 9 in a horizontal position using the suction cup device 7, and then refers to... Figure 12As shown, the flipping device 4 is flipped to a vertical position to enter the waiting state; the support plate 701 is provided with eight vacuum suction cups 702, corresponding to the installation of the left door panel 9 and the right door panel 9. For example, when installing the right door panel 9, the right door panel 9 needs to be limited to the right half of the support plate 701 by the limiting device 6, and then the six vacuum suction cups 702 located on the right side of the support plate 701 are used to grab the door panel 9.

[0038] S3, manually push the equipment close to the box, then push the flipping device 4 to send the door panel 9 into the door frame of the box, manually move the hinge to stick it to the outer wall of the box, when the bolt holes on the hinge are aligned with the bolt holes on the box, use the positioning component 703 in the suction cup device 7 to fix the door panel 9 together with the support plate 701 to the outer wall of the equipment. In step S3, after the bolt holes on the hinge of the door panel 9 are aligned with the bolt holes on the outer wall of the equipment, the pneumatic suction cups 7032 in the upper and lower positioning components 703 are used to suction the outer wall of the equipment. Then, the suction cup bracket 7031 and the pneumatic suction cups 7032 are fixed together by the locking nut 7035, thereby firmly fixing the door panel 9 together with the support plate 701 to the outer wall of the equipment.

[0039] S4, adjust the height of the two sleeve mounting seats 502 according to the height of the hinge, and then adjust the distance between the first power shaft 503 and the second power shaft 504 in each sleeve mounting seat 502 separately so that they correspond to the bolt holes on the hinge respectively. Insert the bolts into the sleeves and slowly move the tightening device 5 to insert the bolts in the sleeves into the corresponding bolt holes. S4.1 During the adjustment of the tightening device 5, the distance between the two sleeves needs to be adjusted according to the distance between the two bolt holes on the hinge. First, the distance between the first power shaft 503 and the second power shaft 504 is adjusted by rotating the manual screw 5022, and sleeves are installed on both the first power shaft 503 and the second power shaft 504. Then, the height of each sleeve mounting seat 502 is adjusted individually by adjusting the screw 5011, so that the upper sleeve mounting seat 502 is aligned with the upper bolt hole of the upper hinge, and the lower sleeve mounting seat 502 is aligned with the lower bolt hole of the lower hinge, so as to achieve the purpose of precisely adjusting the height of the two sleeve mounting seats 502. After that, the camera 509 takes pictures of the bolt status inside the sleeve to confirm that the bolt is not tilted or missing material. If an abnormality is detected, step S5.2 is executed, and the insertion action is not required, reducing the risk of mechanical interference.

[0040] In step S4.1, when adjusting the first power shaft 503 and the second power shaft 504 on any sleeve mounting base 502, since the first power shaft 503 is fixed, the distance between the first power shaft 503 and the second power shaft 504 can be adjusted by adjusting the height of the second power shaft 504 through the corresponding manual screw 5022.

[0041] S5, start the servo motor 508 and tighten the bolts.

[0042] To ensure the stability and controllability of the bolt during the tightening process, in step S5, the controller controls the number of rotations of the output shaft of the servo motor 508 to ensure that the bolt rotation torque is consistent. That is, the controller sends instructions to the servo motor 508 to ensure that the number of rotations of the output shaft is consistent whether it rotates forward, reverse, or a combination of forward and reverse rotation. At the same time, the controller dynamically adjusts the instructions based on the operating status (such as the current number of rotations, speed, etc.) fed back by the servo motor 508 to ensure that the actual number of rotations is consistent with the target number of rotations.

[0043] During the assembly process, this embodiment also provides two corresponding operation mechanisms: Mechanism 1 S5.1, the controller controls the servo motor 508 to perform intermittent tightening operations on the bolts twice.

[0044] S5.1.1, the first operation is a pre-tightening operation, which controls the output shaft of the servo motor 508 to pre-rotate 1 to 2 revolutions.

[0045] S5.1.2, the second is the formal tightening operation, which further controls the output shaft of servo motor 508 to the target number of revolutions.

[0046] The purpose of Mechanism 1 is to address the difficulty in identifying deviations during bolt installation and the potential for forced tightening during manual operation if installation deviations are not identified, thereby preventing the subsequent bolts from becoming difficult to remove due to forced tightening.

[0047] Mechanism 2 S5.2, Detection of abnormal bolt installation. In step S5.1.1, camera 509 captures real-time photos of the corresponding sleeve area. The control terminal compares the real-time photos with pre-imported characteristic photos of abnormal bolt installation to determine whether an abnormal bolt installation has occurred, and changes the bolt installation action according to the abnormality.

[0048] S5.2.1, when no bolt is detected in the sleeve, the controller immediately sends a stop command to the servo motor 508, and the upper frame 1 retracts along the X-axis, causing the tightening device 5 to return to the initial waiting position of the upper frame 1. Simultaneously, the controller sends a material shortage signal, which is generated by determining the coordinates of the missing sleeve through image recognition by the camera 509, and combining this with the number of the sleeve mounting base 502 to generate a unique position code, thus prompting the operator to promptly replenish the bolt in the corresponding empty sleeve. When the tightening device 5 resets, the controller can re-call the camera 509 for confirmation, and then automatically continue executing step S4.

[0049] The material shortage signal specifies which sleeve mounting 502 and which drive shaft is missing material, so that it can be added accurately.

[0050] S5.2.2, when only a single bolt is detected tilting within the sleeve, the controller first disconnects the electromagnetic clutch 5010 on the side with the normal bolt, disengaging it and breaking the power connection between the servo motor 508 and the power shaft on that side. This ensures the bolt on that side remains stationary and no longer participates in subsequent error correction actions, thus preventing it from generating additional stress or torsion on the hinge. Secondly, the controller controls the servo motor 508 to rotate in the opposite direction. Since only the electromagnetic clutch 5010 on the side with the abnormal bolt remains engaged, power is transmitted to the sleeve driving the tilted bolt on that side, slowly unscrewing the tilted bolt until it is completely removed from the bolt hole. During the bolt removal process, the tightening device 5 retracts a distance along the X-axis to allow the sleeve and bolt to completely separate.

[0051] Next, the operator inserts a new bolt into the sleeve and repeats step S4 to continue the hinge installation process.

[0052] S5.2.3, when it is detected that both bolts are tilted inside the sleeves, the electromagnetic clutches 5010 of the two sleeves remain engaged. Simultaneously, the servo motor 508 rotates synchronously in the opposite direction at a lower speed and torque. The reverse torque of the servo motor 508 is limited to 50% of the forward torque. This reverse torque can be fed back in real-time through the encoder of the servo motor 508. If the torque exceeds the threshold, the operation stops immediately to avoid damage to the bolts or hinges. After the two sleeves smoothly remove the two tilted bolts from the bolt holes, the force on the two hinges is simultaneously released, preventing new torsional deformation of the door panel 9 or hinges due to one side exiting first. After the two bolts are removed, the door panel 9 remains fixed to the outer wall of the equipment by the positioning assembly 703. At this time, the hinges may not be fully fitted to the outer wall of the equipment, requiring the operator to re-align and calibrate. Subsequently, the operator needs to add new bolts to the sleeves or readjust the bolt condition before the equipment can re-execute the positioning operation of step S4 and the tightening process of step S5.

[0053] In step S5.2.2, the purpose is to address the issue of immediately driving the sleeve to rotate in the opposite direction when the abnormality is detected. However, rotating both bolts in the opposite direction at the same time may cause deformation or skewness of the hinge. That is, using a simple simultaneous reverse rotation exit operation will cause an uncontrollable deviation in the relative position of the bolt holes on the hinge and the bolt holes on the outer wall of the equipment. Therefore, step S5.2.2 actually provides a reset mechanism to avoid repositioning of the bolt holes. Since the normal bolts have not been displaced, the relative position of the hinge and the outer wall of the equipment is temporarily fixed by the bolts, avoiding overall positional shift, thus eliminating the need to reposition the bolt holes.
