Description

Technical Field

[0001] This invention relates to the field of automated assembly technology, specifically to an automated assembly robot for metal fasteners. Background Technology

[0002] Metal fasteners, as core components in the field of mechanical connections, are widely used in numerous industries such as automobile manufacturing, engineering machinery, electronic equipment, and construction machinery. Their assembly quality directly affects the structural stability, connection reliability, and service life of products. With the transformation of manufacturing towards automation and intelligence, traditional manual tightening of fasteners can no longer meet the efficiency, precision, and consistency requirements of modern mass production. Automated assembly robots for metal fasteners have emerged to address this need. These robots integrate functional modules such as gripping, positioning, and tightening, enabling automated operation of fasteners from feeding and conveying to precise tightening to the workpiece's preset installation position. This significantly improves assembly efficiency, reduces manual labor intensity, and effectively ensures the accuracy of fastener tightening torque and assembly consistency, making them an indispensable key piece of equipment on modern industrial production lines.

[0003] For example, the invention disclosed in CN109227103B is an automatic fastener assembly robot. This invention can simultaneously carry multiple fasteners and tool sleeves, and can accurately and automatically pick up the required fasteners. However, in actual use, when different bolts need to be replaced, a series of sleeve removal and replacement operations must be performed before different types of bolts can be picked up, resulting in reduced assembly efficiency due to the large number of operation steps during switching. Summary of the Invention

[0004] The purpose of this invention is to provide an automated assembly robot for metal fasteners to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic assembly robot for metal fasteners, comprising a base and an adjustment assembly. A movable assembly is mounted on the top of the base, and the output end of the movable assembly is connected to a mounting base. A motor is fixed on one side of the mounting base, and the output end of the motor is connected to a drive shaft. A synchronous shaft is rotatably connected to the end of the drive shaft. The adjustment assembly is connected to the upper part of the mounting base and includes an electric push rod. The electric push rod is fixed on the upper part of the mounting base, and a bearing seat is mounted on the output end of the electric push rod. A protective cover is rotatably connected inside the bearing seat, and a drive ring is fixed on one side of the protective cover. A first connecting ear is rotatably connected to one side of the drive ring, and a rotating plate is rotatably connected to one end of the first connecting ear. A second connecting ear is rotatably connected to one end of the rotating plate, and a slide is rotatably connected to one side of the second connecting ear. A clamping block is fixed to one end of the slide, and a guide plate is slidably connected to the outer side of the slide.

[0006] Furthermore, the guide plate is fixedly connected to the synchronous shaft, and the synchronous shaft is slidably connected to the drive ring.

[0007] Furthermore, six first connecting ears are provided, and the first connecting ears are distributed in an equidistant circle along one side of the drive ring.

[0008] Furthermore, the moving component includes a first linear module, a second linear module, and a third linear module. The first linear module is mounted on the top of the base, and the output end of the first linear module is connected to the second linear module, while the output end of the second linear module is mounted on the third linear module.

[0009] Furthermore, the protective cover is provided with a protective component inside, and the protective component includes a compression spring. One end of the protective cover is abutted against the compression spring, and one end of the compression spring is abutted against a slip ring. A ball head post is fixed to one side of the slip ring, and one end of the ball head post is abutted against a fixing ring. A protrusion is fixed to one side of the fixing ring.

[0010] Furthermore, the slip ring is slidably connected to the drive shaft, and the ball joints are equidistantly distributed circumferentially along one side of the slip ring.

[0011] Furthermore, the retaining ring is fixedly connected to the synchronous shaft, and the axis of the synchronous shaft coincides with the axis of the drive shaft.

[0012] Furthermore, the front end of the base is provided with a feeding assembly, which includes a column. A vibratory feeder discharge track is provided on one side of the column, and a transfer seat is provided at one end of the vibratory feeder discharge track. A magnet is fixed inside the upper end of the transfer seat, and a rotating shaft is arranged at the lower part of the transfer seat. A slotted plate is fixed at one end of the rotating shaft, and a sliding column is slidably connected inside the slotted plate. A transmission rod is fixed at one end of the sliding column, and a guide sleeve is slidably connected to the outside of the transmission rod. A return spring abuts against the outside of the transmission rod, and a top rod is fixed at one end of the transmission rod.

[0013] Furthermore, the rotating shaft is rotatably connected to the column, and the column is fixedly connected to the guide sleeve.

[0014] Furthermore, the internal through groove of the slotted plate is obtuse-angled, and the rotatable angle of the slotted plate is 0-90 degrees.

[0015] This invention provides an automated assembly robot for metal fasteners, which has the following advantages: 1. This invention uses an electric push rod to drive the protective cover to move, and a rotating plate drives the slide to adjust the spacing of each clamping block, forming a hexagonal sleeve that can adapt to different bolt specifications. It can quickly adapt to various bolt sizes without changing the sleeve, significantly improving assembly efficiency. When the electric push rod is pulled back, the clamping blocks move synchronously towards the center and firmly clamp the bolt, ensuring that the bolt does not fall off during the transfer and tightening process, enhancing the fit and tightening quality. At the same time, the protective cover and the bearing seat are rotatably connected, decoupling the clamping mechanism from the rotating mechanism. During continuous rotation and tightening, the clamping force remains stable and does not loosen, realizing the independent parallel operation of clamping and rotation, ensuring the continuity and smoothness of automated assembly.

[0016] 2. During the tightening process, the drive shaft and synchronous shaft transmit torque through a slip ring, ball joint, and protrusion. Initially, the compression spring provides clamping force to make the drive shaft and synchronous shaft rotate synchronously. When the tightening resistance increases and the horizontal component of the force exerted by the protrusion on the ball joint exceeds the spring force, the slip ring compresses the spring, causing the ball joint to disengage from the protrusion and automatically cutting off the transmission. This effectively prevents bolt stripping, breakage, and component damage caused by over-tightening, and protects the motor and transmission mechanism from overload impact, improving equipment reliability. When clamping bolts of different specifications, the movement of the protective cover will synchronously change the spring compression, so that large bolts correspond to high torque thresholds and small bolts correspond to low torque thresholds, achieving adaptive matching between torque and bolt specifications. This eliminates the need for manual setting, avoids assembly problems caused by selecting the wrong torque, and reduces operating costs and difficulty.

[0017] 3. This invention uses a vibratory feeder to transport bolts of different specifications to the corresponding slot transfer seat via a discharge track. Magnetic adsorption of the bolt heads ensures stable fit and accurate positioning, preventing them from falling off during flipping. During the material handling process, the moving component drives the guide plate to press the top rod, which in turn drives the slot plate to rotate 90 degrees and lock its position via a transmission rod and sliding column. The clamping block then picks up the bolt, while the transfer seat blocks the discharge port. After material handling, the reset spring causes the transfer seat to rotate and align with the discharge port, preparing for the next feeding. The entire process relies on the preset path of the moving component and mechanical linkage to achieve fully automatic connection of positioning, conveying, gripping, and reset, requiring no additional sensors. The process is continuous and reliable, reducing equipment cost and complexity. Attached Figure Description

[0020] Please see Figures 1 to 5This invention provides a technical solution: an automatic assembly robot for metal fasteners, comprising a base 1 and an adjustment component 7. A moving component 2 is mounted on the top of the base 1, and the output end of the moving component 2 is connected to a mounting base 3. The moving component 2 includes a first linear module 201, a second linear module 202, and a third linear module 203. The first linear module 201 is mounted on the top of the base 1, and the output end of the first linear module 201 is connected to the second linear module 202. The output end of the second linear module 202 is mounted to the third linear module 203. A motor 4 is fixed on one side of the mounting base 3, and the output end of the motor 4 is connected to a drive shaft 5. A synchronous shaft 6 is rotatably connected to the end of the drive shaft 5. The adjustment component 7 is connected to the upper part of the mounting base 3, and the adjustment component 7 includes an electric push rod 701. An electric push rod 701 is fixed on the upper part of the mounting base 3. A push rod 701 is provided, and a bearing seat 702 is installed at the output end of the electric push rod 701. A protective cover 703 is rotatably connected inside the bearing seat 702, and a drive ring 704 is fixed on one side of the protective cover 703. A first connecting ear 705 is rotatably connected to one side of the drive ring 704, and a rotating plate 706 is rotatably connected to one end of the first connecting ear 705. Six first connecting ears 705 are provided, and the first connecting ears 705 are equidistantly distributed in a circle along one side of the drive ring 704. A second connecting ear 707 is rotatably connected to one end of the rotating plate 706, and a slide 708 is rotatably connected to one side of the second connecting ear 707. A clamping block 709 is fixed to one end of the slide 708, and a guide plate 710 is slidably connected to the outside of the slide 708. The guide plate 710 is fixedly connected to the synchronous shaft 6, and the synchronous shaft 6 is slidably connected to the drive ring 704. The specific operation is as follows: When picking up bolts of different sizes, the electric push rod 701 can be activated by the controller, causing it to slide the protective cover 703 outside the synchronous shaft 6 via the bearing seat 702. When the distance between the drive ring 704 and the guide plate 710 shortens, the rotating plate 706 will push the slide 708 to slide in the straight hole inside the guide plate 710. At the same time, the first connecting ear 705 and the second connecting ear 707 can adaptively rotate, thereby avoiding motion interference. Therefore, the slide 708 can expand the size of the hexagon formed between the six clamping blocks 709 during the movement, forming bolt sleeves of various specifications. Compared with existing fastener automatic assembly robots, this invention does not require the disassembly and replacement of sleeves, thereby improving assembly efficiency. When the electric push rod 701 pulls the bearing seat 702 to drive the protective cover 703 to slide outside the synchronous shaft 6, the electric push rod 701 can slide the protective cover 703 outside the synchronous shaft 6. When ring 704 moves back, as the distance between drive ring 704 and guide plate 710 increases, rotating plate 706 pulls all slide blocks 708 to move centrally, causing all clamping blocks 709 to move synchronously towards the center and clamp the bolt, preventing the bolt from falling off during the transfer process and improving the stability when picking up and putting down the bolt. In addition, it can also enhance the fit between the clamping block and the bolt head, thereby improving the final tightening effect and quality. Furthermore, since bearing seat 702 and protective cover 703 are rotatably connected, the driving clamping mechanism and the rotating mechanism are decoupled in motion, ensuring that the clamping force of clamping block 709 will not be accidentally released or changed due to the rotation of the mechanism during the entire process of continuously rotating and tightening the bolt. This achieves perfect parallelism and non-interference between the clamping and rotating actions, ensuring the continuity and smoothness of the automated assembly process.

[0021] Please see Figure 3 The protective cover 703 is provided with a protective component 8, and the protective component 8 includes a compression spring 801. One end of the protective cover 703 is abutted against the compression spring 801, and one end of the compression spring 801 is abutted against a slip ring 802. A ball head post 803 is fixed on one side of the slip ring 802, and one end of the ball head post 803 is abutted against a fixing ring 804. The slip ring 802 is slidably connected to the drive shaft 5, and the ball head posts 803 are equidistantly distributed circumferentially along one side of the slip ring 802. The fixing ring 804 is fixedly connected to the synchronous shaft 6, and the axis of the synchronous shaft 6 coincides with the axis of the drive shaft 5. A protrusion 805 is fixed on one side of the fixing ring 804. The specific operation is as follows: During the bolt tightening process, when the motor 4 drives the drive shaft 5 to rotate, it will first drive the slip ring 802 to rotate synchronously. At this time, the compression spring 801 will push the slip ring 802 under the limiting action of the protective cover 703, so that the ball head 803 and the fixed ring 804 are pressed together. At the same time, the ball head 803 will also fit with the protrusion 805, thereby pushing the protrusion 805 to make the fixed ring 804 rotate synchronously, transmitting power to the synchronous shaft 6, so that the clamping block 709 can drive the bolt to rotate to perform the tightening operation. During this process, the protrusion 802... The curved surface of drive shaft 5 generates a horizontal component force on ball joint 803. When this component force is less than the elastic force of compression spring 801, drive shaft 5 and synchronous shaft 6 will rotate synchronously. After tightening the bolt, the resistance on synchronous shaft 6 will increase, which in turn will gradually increase the horizontal force exerted by protrusion 805 on ball joint 803. When this thrust is greater than the elastic force of compression spring 801, slip ring 802 will squeeze compression spring 801, causing ball joint 803 to avoid protrusion 805. Therefore, there is a distance between drive shaft 5 and synchronous shaft 6. The automatic disconnection of the transmission effectively prevents bolt stripping, breakage, or damage to connected parts caused by overtightening. It also protects the motor 4 and transmission mechanism from overload impact, improving equipment reliability and service life, thus providing protection. When clamping bolts of different sizes, when the protective cover 703 moves towards the guide plate 710 to make the clamping block 709 adaptable to larger bolts, the protective cover 703 will simultaneously compress the compression spring 801, thereby increasing the transmittable torque threshold. When the protective cover 703 moves away from the guide plate 710 to make the guide plate 710 adaptable to smaller bolts, the compression spring 801 will also extend simultaneously, correspondingly reducing the torque threshold. This means that high torque is automatically activated when clamping large bolts, and low torque is automatically switched when clamping small bolts. This adaptive matching avoids the tediousness of manually setting or changing torque sleeves for different bolts, realizing intelligent following of torque and bolt specifications, greatly expanding the application range of the equipment, and fundamentally eliminating assembly quality problems caused by selecting the wrong torque. There is no need to add an additional complex control system, reducing the cost of use and the operating threshold.

[0022] Please see Figure 6 and Figure 7The base 1 has a feeding assembly 9 at its front end, which includes a column 901. A vibratory feeder discharge track 902 is provided on one side of the column 901, and a transfer seat 903 is provided at one end of the vibratory feeder discharge track 902. A magnet 904 is fixed inside the upper end of the transfer seat 903, and a rotating shaft 905 is installed at the lower part of the transfer seat 903. A slotted plate 906 is fixed at one end of the rotating shaft 905, and a sliding column 9 is slidably connected inside the slotted plate 906. 07. The internal through groove of the slotted plate 906 is obtuse-angled, and the rotatable angle of the slotted plate 906 is 0-90 degrees. One end of the sliding column 907 is fixed with a transmission rod 908, and the outer side of the transmission rod 908 is slidably connected with a guide sleeve 909. The rotating shaft 905 is rotatably connected with the column 901, and the column 901 is fixedly connected with the guide sleeve 909. The outer side of the transmission rod 908 abuts against a return spring 910, and one end of the transmission rod 908 is fixed with a top rod 911. The specific operation is as follows: the external screening vibratory feeder can transport bolts of different specifications to different vibratory feeder discharge tracks 902. Compared with the existing insert plate feeding method, there is no need to insert the bolts one by one into the insert plate in advance, nor is it necessary to flip and adjust the insert plate, thereby reducing the pre-operation steps during material picking and realizing uninterrupted bolt feeding. After the vibratory feeder discharge track 902 transports the bolts to the transfer seat 903 with corresponding large and small slots, the magnet 904 will attract its head to the inner wall of the slot, which significantly improves the fit stability and positioning accuracy between the bolt and the tooling, and also prevents the bolt from falling off due to subsequent flipping. During the material picking process, the moving component 2 will drive the guide plate 710 to press the top rod 911. Under the guidance of the guide sleeve 909, the transmission rod 908 will drive the sliding column 907 to slide in the through slot in the slot plate 906, thereby pushing the slot plate 906 to rotate 90 degrees around the rotating shaft 905, so that the transfer seat 903 can send the bolt to the slot. In front of the clamping center of the clamping block 709, as the guide plate 710 continues to move forward, the sliding column 907 will slide on another section of the through groove inside the slot plate 906, which can lock the angle of the transfer seat 903, ensuring absolute rigidity at the moment of gripping. At this time, the clamping block 709 can clamp and remove the bolt, and the transfer seat 903 will also block the discharge port of the vibratory feeder discharge track 902. After the bolt is removed, when the guide plate 710 separates from the top rod 911, the reset spring 910 pushes the transmission rod 908 to move back and reset. The transfer seat 903 will then rotate to align its groove with the discharge port of the vibratory feeder discharge track 902, preparing for the next material removal. The whole process only requires the moving component 2 to drive the adjusting component 7 to move and work according to the preset path. There is no need to add additional sensors to judge the status. Relying on the pure mechanical timing and position coordination, the seamless connection of positioning, conveying, gripping and resetting is achieved. Not only is the process highly consistent, but the equipment cost is also reduced.

[0023] In summary, this automatic assembly robot for metal fasteners first uses an external positioning fixture or robotic arm to fix the product in front of the robot. Then, an external screening vibratory feeder can transport bolts of different specifications to different vibratory feeder discharge tracks 902, achieving uninterrupted bolt supply. The vibratory feeder discharge tracks 902 then transport the bolts to a transfer seat 903 with corresponding large and small slots. The magnet 904 will attract the bolt head to the inner wall of the slot, improving the fit stability and positioning accuracy between the bolt and the fixture, and also preventing it from falling off during subsequent flipping. Secondly, the adjustment component 7 can be moved along the X, Y and Z axes by the first linear module 201, the second linear module 202 and the third linear module 203, thereby driving the guide plate 710 to press the top rod 911. Under the guidance of the guide sleeve 909, the transmission rod 908 drives the sliding column 907 to slide in the through groove in the slot plate 906, pushing the slot plate 906 to rotate 90 degrees around the pivot 905, so that the transfer seat 903 accurately delivers the bolt to the front of the clamping center of the clamping block 709. The transfer seat 903 will also block the discharge port of the vibratory feeder discharge track 902. Subsequently, as the guide plate 710 continues to move forward, the sliding column 907 will slide in another section of the through groove inside the slot plate 906, which can lock the angle of the transfer seat 903 and ensure absolute rigidity at the moment of gripping. Next, the electric push rod 701 is activated by the controller, causing it to slide the protective cover 703 outside the synchronous shaft 6 via the bearing seat 702. When the distance between the drive ring 704 and the guide plate 710 shortens, the rotating plate 706 pushes the slide 708 to slide in the straight hole inside the guide plate 710. At the same time, the first connecting ear 705 and the second connecting ear 707 can rotate adaptively to avoid motion interference. Therefore, the slide 708 can expand the size of the hexagon formed between the six clamping blocks 709 during the movement, forming bolt sleeves of various specifications. When the electric push rod 701 pulls the bearing seat 702 to move the drive ring 704 back, as the distance between the drive ring 704 and the guide plate 710 increases, the rotating plate 706 will pull all the slides 708 to move in the center, so that all the clamping blocks 709 move towards the center synchronously and clamp the bolts, preventing the bolts from falling off during the transfer process and improving the stability of bolt picking and putting. Then, after clamping and removing the bolt by clamping block 709, when the guide plate 710 separates from the push rod 911, the return spring 910 pushes the transmission rod 908 back to its original position. The material transfer seat 903 will then rotate to align its groove with the discharge port of the vibratory feeder discharge track 902, preparing for the next material removal. Afterward, the moving component 2 moves the bolt to the threaded hole of the product. When the motor 4 drives the drive shaft 5 to rotate, it will first drive the slip ring 802 to rotate synchronously. At this time, the compression spring 801 will push the slip ring 802 under the limiting action of the protective cover 703, so that the ball head 803 abuts against the fixed ring 804. At the same time, the ball head 803 will also fit against the protrusion 805, thereby pushing the protrusion 805 to make the fixed ring 804 rotate synchronously, transmitting power to the synchronous shaft 6, so that clamping block 709 can drive the bolt to rotate to perform tightening. During operation, the arc surface of the protrusion 805 will generate a horizontal component force on the ball head post 803. When this component force is less than the elastic force of the compression spring 801, the drive shaft 5 and the synchronous shaft 6 will rotate synchronously. After tightening the bolt, the resistance on the synchronous shaft 6 will increase, which will cause the horizontal force exerted by the protrusion 805 on the ball head post 803 to gradually increase. When this thrust is greater than the elastic force of the compression spring 801, the slip ring 802 will squeeze the compression spring 801, causing the ball head post 803 to avoid the protrusion 805. Therefore, the transmission between the drive shaft 5 and the synchronous shaft 6 will be automatically disconnected. This effectively prevents the bolt from stripping, breaking or being damaged by the connecting parts due to overtightening. It also protects the motor 4 and the transmission mechanism from overload impact, improves the reliability and service life of the equipment, and thus plays a protective role. Finally, when clamping bolts of different sizes, when the protective cover 703 moves towards the guide plate 710 to make the clamping block 709 adaptable to larger bolts, the protective cover 703 will simultaneously compress the compression spring 801, thereby increasing the transmittable torque threshold. When the protective cover 703 moves away from the guide plate 710 to make the guide plate 710 adaptable to smaller bolts, the compression spring 801 will also extend simultaneously, correspondingly reducing the torque threshold. This means that high torque is automatically activated when clamping large bolts, and low torque is automatically switched when clamping small bolts. This adaptive matching avoids the tediousness of manually setting or changing torque sleeves for different bolts, realizes intelligent following of torque and bolt specifications, greatly expands the application range of the equipment, and fundamentally eliminates assembly quality problems caused by selecting the wrong torque. There is no need to add an extra complex control system, reducing the cost of use and the operating threshold.
