Description

Technical Field

[0001] This invention belongs to the field of tightening equipment technology, and particularly relates to an intelligent balancing lever tightening device. Background Technology

[0002] The intelligent balancing arm tightening machine is a human-machine collaborative intelligent bolt tightening equipment, mainly composed of an industrial camera, a balancing assist arm, a servo intelligent tightening device, and a controller. It is used for nut and bolt fastening operations in industrial production lines, combining the flexibility of handheld operation with the precision control and error prevention capabilities of automated tightening operations.

[0003] In the current intelligent balancing arm tightening machine, product identification is generally achieved by an industrial camera. The system can retrieve matching torque parameters from the database based on the identified product type to avoid problems of excessive or insufficient torque during tightening operations.

[0004] However, the industrial cameras of existing intelligent balancing arm tightening machines lack corresponding protective structures. When the equipment is not in operation, the industrial camera lens cannot be shielded and protected. During production line shutdowns, off-duty hours, or holiday shutdowns, the exposed industrial camera lens is prone to accumulating environmental dust. This leads to the need for frequent cleaning and maintenance of the lens during long-term operation of the equipment. Repeated cleaning operations will cause wear on the lens surface, thereby shortening the actual service life of the industrial camera.

[0005] Therefore, it is necessary to provide a new intelligent balancing lever arm tightening device to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent balancing lever arm tightening device to solve the problems mentioned in the background section of the prior art.

[0007] To address the aforementioned problems, this invention proposes an intelligent balancing lever tightening device, comprising: a housing with two through holes on its top, each through hole housing a support rod, the top ends of the two support rods being fixedly mounted on a common top plate, and an industrial camera for photographing the product and identifying the tightening point of the nut being fixedly mounted on the bottom of the top plate; an intelligent lever arm fixedly mounted on the top of the housing for tightening the product nut, the intelligent lever arm being equipped with a tightening device; a placement plate fixedly mounted on one side of the housing, the top of the placement plate being equipped with a barcode scanner for tracing the product; a lifting mechanism mounted on the housing for raising and lowering the top plate; and a protective mechanism mounted on the top plate for shielding the industrial camera.

[0008] Preferably, the lifting mechanism includes: a servo motor fixedly installed on the inner wall of one side of the housing; a screw rotatably installed on the top of the housing, the bottom end of the screw being fixedly connected to the output shaft of the servo motor, a lifting plate being threaded onto the screw, one side of the lifting plate being slidably connected to the inner wall of one side of the housing, and the top of the lifting plate being fixedly connected to the bottom ends of the two support rods.

[0009] Preferably, the protective mechanism includes: two support blocks fixedly installed on one side of the top plate, with a common connecting frame hinged between the two support blocks; an arc-shaped rod slidably installed on the connecting frame, one end of the arc-shaped rod being fixedly connected to the top of the top plate; a spring slidably sleeved on the arc-shaped rod, one end of the spring being fixedly connected to the top of the top plate; a vertical plate fixedly installed on one side of the connecting frame, with a pull rope fixedly installed on the vertical plate, one end of the pull rope being fixedly connected to the top of the housing; a cover fixedly installed at one end of the connecting frame, the cover being used to cover the industrial camera; and two first U-shaped frames fixedly installed on the top of the top plate, each of the two first U-shaped frames having two U-shaped blocks fixedly installed on its inner side, and multiple first guide wheels rotatably installed on multiple U-shaped blocks, with multiple first guide wheels in contact with the pull rope.

[0010] Preferably, a second U-shaped frame is fixedly installed on the top of the top plate, and a second guide wheel is rotatably installed on the second U-shaped frame, the second guide wheel being in contact with the pull rope.

[0011] Preferably, the distance between the second guide wheel and the inner side of the top of the second U-shaped frame is 2mm, and the pull rope is a steel wire rope.

[0012] Preferably, a sealing ring is fixedly installed on the side of the cover near the industrial camera. The sealing ring is shaped like an opening and is used to fit the bottom of the top plate.

[0013] Preferably, the two support rods are equipped with the same main controller, which is used to analyze the images captured by the industrial camera.

[0014] Preferably, one of the first U-shaped frames is inclined, and the four corners of the box are provided with rubber strips for anti-collision.

[0015] Compared with related technologies, the intelligent balancing lever arm tightening device provided by the present invention has the following beneficial effects: Compared with existing technologies, the intelligent balancing arm tightening device provided in this solution retains all the original advantages of the intelligent arm tightening system, including arm assistance, position error prevention, high-precision torque closed loop, visual "plus" red light dual guidance, and scanning MES data traceability. It adds a lifting mechanism and a protective mechanism linked to the lifting mechanism. When the device is not in use and the lifting mechanism is activated to drive the top plate down, the cover on the protective mechanism can shield the industrial camera from dust, and vice versa. There is no need for manual operation of the cover protecting the industrial camera. In addition, during equipment operation, the top plate rises and the cover opens automatically to ensure normal image capture and recognition by the industrial camera. When the equipment is stopped and in standby mode, the top plate descends and the cover closes automatically to seal and shield the industrial camera, effectively preventing dust from the environment from contaminating the lens surface of the industrial camera. This significantly reduces the frequency of lens cleaning and maintenance, avoids repeated wiping that causes wear on the lens surface, extends the service life of the industrial camera, ensures stable visual recognition accuracy, and avoids quality risks such as point recognition errors, mismatched tightening process parameters, and poor bolt fastening caused by lens contamination.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This invention provides an intelligent balancing lever arm tightening device, such as... Figure 1-5 As shown, the intelligent balancing arm tightening device includes: a housing 1, with two through holes 2 on the top of the housing 1, each through hole 2 containing a support rod 3, the top of the two support rods 3 being fixedly mounted on the same top plate 4, and an industrial camera 5 for photographing the product and identifying the tightening point of the nut being fixedly mounted on the bottom of the top plate 4; an intelligent arm 6 fixedly mounted on the top of the housing 1 for tightening the product nut, the intelligent arm 6 being equipped with a tightening device; a placement plate 7 fixedly mounted on one side of the housing 1, the top of the placement plate 7 being equipped with a barcode scanner 8 for tracing the product; a lifting mechanism 9 mounted on the housing 1 for raising and lowering the top plate 4; and a protective mechanism 10 mounted on the top plate 4 for shielding the industrial camera 5.

[0020] In this embodiment, it should be noted that a red light guiding device is also provided on the edge of the top plate 4, and a torque controller and IO module are also provided inside the housing 1. When the intelligent balancing arm tightening device is working, the lifting mechanism 9 first drives the support rod 3 to move up and down along the perforation 2 at the top of the housing 1, thereby driving the top plate 4 to complete the height adjustment, so that the top plate 4 is at the corresponding working height. When the equipment is in the working mode, the protective mechanism 10 remains open to remove the obstruction of the lens of the industrial camera 5 at the bottom of the top plate 4. Then, the operator places the workpiece to be processed on the working position of the housing 1. The barcode scanner 8 on the top of the placement plate 7 scans the workpiece barcode to complete the workpiece ID binding and can trace the product. The main controller 14 retrieves the tightening process formula of the corresponding workpiece. The intelligent arm 6 has a built-in encoder to collect real-time position coordinates to realize the position error prevention constraint of the tightening point and the tightening operation sequence. The industrial camera 5 takes pictures of the workpiece for comparison and identification to confirm the workpiece model and the nut tightening point. With the help of the red light guiding device, the positioning guidance is output. The operator relies on the intelligent arm tightening device to tighten the workpiece. The lever arm 6 counteracts the reaction force generated by the tightening device and its own weight, reducing the manual operation load. Following the guide points, the intelligent lever arm 6 drives the tightening device to perform bolt and nut fastening operations. The tightening device, in conjunction with a torque controller, achieves closed-loop torque control, performing real-time torque acquisition and correction to ensure tightening torque accuracy. During operation, the main controller 14 collects torque, angle, and position operation data in real time, completes data storage, and can be connected to the MES system for production traceability. After the equipment completes all tightening operations and enters a non-working state of shutdown and standby, the operator can lower the top plate 4 by operating the lifting mechanism 9. During the descent, the protective mechanism 10, in conjunction with the lifting mechanism 9, shields and protects the lens of the industrial camera 5, preventing dust from adhering to the lens surface. Compared with existing technologies, this significantly reduces the frequency of cleaning the industrial camera 5 during long-term use, effectively reducing lens wear and extending the service life of the industrial camera 5, resulting in better performance.

[0021] In a further preferred embodiment of the present invention, the lifting mechanism 9 includes: a servo motor 91 fixedly installed on the inner wall of one side of the housing 1; a screw 92 rotatably installed on the top of the housing 1, the bottom end of the screw 92 being fixedly connected to the output shaft of the servo motor 91, a lifting plate 93 being threadedly installed on the screw 92, one side of the lifting plate 93 being slidably connected to the inner wall of one side of the housing 1, and the top of the lifting plate 93 being fixedly connected to the bottom ends of two support rods 3.

[0022] In this embodiment, when the lifting mechanism 9 is in use, the servo motor 91 is started, and the output shaft of the servo motor 91 drives the screw 92 to rotate synchronously. The rotation of the screw 92 drives the lifting plate 93, which is threadedly installed with it, to slide vertically along the inner side wall of the housing 1. During the up-and-down movement of the lifting plate 93, it drives the two support rods 3, which are fixedly connected to its top, to move synchronously. The support rods 3 pass through the through holes 2 opened at the top of the housing 1 to achieve vertical displacement. The two support rods 3 together drive the top plate 4 to complete the lifting adjustment. In this way, when the device is not in use, the overall height of the device can be reduced, so that the high device can save space during transportation and storage. During the descent of the top plate 4, it can synchronously drive the protective mechanism 10 to shield and protect the industrial camera 5. Conversely, when the servo motor 91 stops outputting power, the screw 92 locks and positions itself, so that the lifting plate 93, the support rods 3 and the top plate 4 remain at the current height position.

[0023] In a further preferred embodiment of the present invention, the protective mechanism 10 includes: two support blocks 101 fixedly installed on one side of the top plate 4, the two support blocks 101 being hinged together by the same connecting frame 102, an arc-shaped rod 103 slidably installed on the connecting frame 102, one end of the arc-shaped rod 103 being fixedly connected to the top of the top plate 4, and a spring 104 slidably sleeved on the arc-shaped rod 103, one end of the spring 104 being fixedly connected to the top of the top plate 4; and a vertical plate 105 fixedly installed on one side of the connecting frame 102. A pull rope 107 is fixedly installed on the 05, and one end of the pull rope 107 is fixedly connected to the top of the box 1; a cover 106 is fixedly installed on one end of the connecting frame 102, and the cover 106 is used to cover the industrial camera 5; two first U-shaped frames 108 are fixedly installed on the top of the top plate 4, and two U-shaped blocks 109 are fixedly installed on the inner side of each of the two first U-shaped frames 108. A first guide wheel 1010 is rotatably installed on each of the multiple U-shaped blocks 109, and the multiple first guide wheels 1010 are in contact with the pull rope 107.

[0024] In this embodiment, when the lifting mechanism 9 lifts the top plate 4 upward, the top plate 4 simultaneously moves the support block 101, connecting frame 102, vertical plate 105, and cover 106 upward together. The pull rope 107 is guided and reversed via the first guide wheel 1010 rotatably mounted on the U-shaped block 109 inside the first U-shaped frame 108. As the top plate 4 rises, the pull rope 107 is gradually tightened, pulling the vertical plate 105, causing the connecting frame 102 to rotate around the hinged position of the two support blocks 101. The connecting frame 102 slides relative to the arc rod 103 and compresses the spring 104 sleeved on the arc rod 103. At this time, the spring 104 is stressed and stores energy. The rotation of the connecting frame 102 causes the cover 106 to deflect away from the lens position of the industrial camera 5, removing the obstruction to the industrial camera 5, allowing the industrial camera 5 to normally complete the workpiece photography and comparison and nut tightening point identification. When the equipment is stopped and in standby mode... The lifting mechanism 9 drives the top plate 4 to fall downwards. The top plate 4 drives the support block 101 and the connecting frame 102 to fall synchronously. The pull rope 107 gradually loosens. At this time, the spring 104, which is in an energy storage state, releases its elastic force. The spring 104 pushes the connecting frame 102 to slide in the opposite direction along the arc rod 103. The connecting frame 102 rotates at the hinge of the support block 101, driving the cover 106 to rotate until it covers the industrial camera 5, thus sealing and blocking the lens of the industrial camera 5 and preventing dust and pollutants from adhering to the surface of the lens of the industrial camera 5. The first guide wheel 1010 rotates and guides the pull rope 107 throughout the entire process of pulling and releasing, reducing the friction and wear of the pull rope 107 and ensuring that the opening and closing action of the cover 106 is smooth and stable. When the equipment is restarted, the lifting mechanism 9 drives the top plate 4 to rise, repeating the above action of the pull rope 107 tightening to overcome the elastic force of the spring 104 and lifting the cover 106. The industrial camera 5 resumes its visual recognition working state, which is relatively convenient to use.

[0025] In a further preferred embodiment of the present invention, a second U-shaped frame 11 is fixedly installed on the top of the top plate 4, and a second guide wheel 12 is rotatably installed on the second U-shaped frame 11, the second guide wheel 12 being in contact with the pull rope 107.

[0026] In this embodiment, the contact between the second guide wheel 12 and the pull rope 107 can further limit and guide the direction of the pull rope 107. Together with the first guide wheel 1010, the pull rope 107 is constrained in multiple positions, which can effectively prevent the pull rope 107 from deviating, running off course, or scraping and getting stuck with surrounding parts during the lifting and lowering of the top plate 4 and the opening and closing of the cover 106 of the protective mechanism 10. This reduces the frictional resistance and wear of the pull rope 107 during the sliding process.

[0027] In a further preferred embodiment of the present invention, the distance between the second guide wheel 12 and the inner side of the top of the second U-shaped frame 11 is 2mm, and the pull rope 107 is a steel wire rope.

[0028] In this embodiment, a 2mm gap is provided between the second guide wheel 12 and the inner top of the second U-shaped frame 11, which allows for the pull rope 107 to move and avoid being squeezed and clamped by the second U-shaped frame 11 during the rotation of the second guide wheel 12, thus avoiding jamming and damage to the pull rope 107. The pull rope 107 is made of steel wire rope, which has the characteristics of high tensile strength and is not easy to stretch and deform. At the same time, steel wire rope is wear-resistant and fatigue-resistant, and can withstand the dusty and oily environment of the production line. It is not easy to break and damage, which can reduce the replacement and maintenance frequency of the pull rope 107.

[0029] In a further preferred embodiment of the present invention, a sealing ring 13 is fixedly installed on the side of the cover 106 near the industrial camera 5. The sealing ring 13 is shaped like an opening and is used to fit the bottom of the top plate 4.

[0030] In this embodiment, when the protective mechanism 10 drives the cover 106 to rotate into position to complete the shielding operation of the industrial camera 5 lens, the orifice-shaped sealing ring 13 can tightly fit the bottom of the top plate 4, forming a closed-loop sealing barrier layer between the cover 106 and the bottom of the top plate 4. This can effectively prevent dust in the production line environment from entering the industrial camera 5 lens position through the gap between the cover 106 and the top plate 4, avoiding contaminants from adhering to the lens through the gap and causing image blurring and position recognition deviation. It also prevents the industrial camera 5 from misidentifying and causing quality problems such as incorrect tightening parameters of the intelligent lever tightening device and unqualified bolt fastening. This can ensure the protective reliability of the industrial camera 5 lens during the standby phase, reduce the frequency of lens cleaning and maintenance, reduce surface wear caused by repeated cleaning, and extend the actual service life of the industrial camera 5.

[0031] In a further preferred embodiment of the present invention, the same main controller 14 is provided on the two support rods 3, and the main controller 14 is used to analyze the images captured by the industrial camera 5.

[0032] In this embodiment, the main controller 14 is mounted and fixed on two support rods 3. The main controller 14 receives workpiece images captured by the industrial camera 5 and performs image analysis to identify the workpiece model and determine the nut tightening point. Combined with the workpiece traceability information obtained by the barcode scanner 8, it retrieves the corresponding tightening process formula and issues operation instructions to the intelligent arm 6 and the tightening device. At the same time, it receives the position signal fed back by the encoder built into the intelligent arm 6 to realize position error prevention for tightening point and tightening sequence. The main controller 14 can also output control signals according to the working status of the equipment, and coordinate the lifting mechanism 9 and the protective mechanism 10 to work together. When the equipment enters the operation mode, it cooperates with the control and protection. Mechanism 10 opens cover 106 to ensure normal image acquisition by industrial camera 5. When the equipment is stopped and in standby mode, it works in conjunction with the control lifting mechanism 9 to lower, triggering the protective mechanism 10 to close cover 106 and block the lens of industrial camera 5. The main controller 14 synchronously collects torque and position data during the tightening process, completes data storage, and supports docking with the MES system to achieve full-process product traceability. This can, to a certain extent, ensure that the images captured by industrial camera 5 can be quickly analyzed and processed, avoiding errors in point identification and accidental triggering of tightening operations due to image processing lag. This ensures the stable and reliable operation of the entire process of visual recognition, error prevention control, tightening operation, and data traceability of the intelligent lever tightening device.

[0033] In a further preferred embodiment of the present invention, one of the first U-shaped frames 108 is inclined, and rubber strips for anti-collision are provided at the four corners of the box body 1.

[0034] In this embodiment, the rubber strips installed at the four corners of the housing 1 can buffer and protect the corners of the housing 1 when the equipment is transported or when there is an accidental collision on the production line, absorb the impact force of the collision, and prevent the metal corners of the housing 1 from directly colliding with the surrounding tooling, equipment, and operators.

[0035] In summary, compared with related technologies, this device retains all the original advantages of the intelligent lever tightening system, including lever arm assistance, position error prevention, high-precision torque closed-loop, visual "plus" red light dual guidance, and barcode scanning MES data traceability. It adds a lifting mechanism 9 and a protective mechanism 10 linked to the lifting mechanism 9. This allows the cover 106 on the protective mechanism 10 to shield the industrial camera 5 from dust when the lifting mechanism 9 is activated to lower the top plate 4 in a non-use state, and vice versa, eliminating the need for manual operation of the cover 106 protecting the industrial camera 5. In addition, during equipment operation mode, the top plate 4 is raised and the cover 106 is automatically opened simultaneously to ensure that the industrial camera 5 can take pictures and recognize normally. When the equipment is stopped and in standby mode, the top plate 4 is lowered and the cover 106 is automatically closed to seal and shield the industrial camera 5, effectively preventing dust in the environment from contaminating the lens surface of the industrial camera 5, greatly reducing the frequency of lens cleaning and maintenance, avoiding repeated wiping that causes wear on the lens surface, extending the service life of the industrial camera 5, ensuring stable visual recognition accuracy, and avoiding quality risks such as point recognition errors, mismatch of tightening process parameters, and poor bolt fastening caused by lens contamination.
