Description

Technical Field

[0001] This application relates to the technical field, and in particular to an automatic positioning and assembly device for anti-loosening gaskets. Background Technology

[0002] In industrial production, component assembly is a crucial step in ensuring product manufacturing quality and efficiency. With the continuous development of the manufacturing industry, the requirements for assembly precision and automation of various components are becoming increasingly stringent. Especially in the manufacturing of equipment with extremely high stability and reliability requirements, the precise positioning and efficient assembly of components directly affect the performance and lifespan of the entire product. Anti-loosening washers, as a commonly used mechanical component, are widely used in various mechanical equipment. Their main function is to prevent bolts and other connecting parts from loosening, ensuring the stable operation of the equipment. Therefore, achieving automatic positioning and assembly of anti-loosening washers is of great significance for improving production efficiency and reducing labor costs.

[0003] In traditional anti-loosening washer assembly operations, common methods include manual assembly, assembly with the aid of simple tooling, and partial assembly using basic automated equipment. In manual assembly, workers must pick up each anti-loosening washer individually and precisely install it onto the bolt. Assembly with simple tooling utilizes basic tools to assist workers in completing the assembly, such as clamps of specific shapes to help workers better hold the washer. Partial assembly using basic automated equipment typically uses a vibratory feeder to arrange the anti-loosening washer neatly and transport it to a designated location, but subsequent operations such as picking, positioning, and installation still require manual intervention.

[0004] Because the outer periphery of the anti-loosening gaskets is irregularly shaped, pre-assembly material selection is challenging, while assembly also requires a certain level of precision. Traditional manual assembly methods are extremely inefficient and easily affected by human factors such as worker fatigue and mood, leading to inconsistent assembly quality. While simple semi-automated assembly uses basic mechanical equipment to assist in some assembly work—for example, using a vibratory feeder to arrange the anti-loosening gaskets neatly and transport them to designated positions—subsequent material handling, positioning, and installation still require manual intervention. This prevents full automation and still results in low assembly efficiency and high labor intensity. Summary of the Invention

[0005] In order to effectively realize the automatic positioning and assembly of anti-loosening gaskets and significantly improve the efficiency and accuracy of assembly work, the present invention provides an automatic positioning and assembly device for anti-loosening gaskets.

[0006] The automatic positioning and assembly device for anti-loosening gaskets provided by this invention adopts the following technical solution: An automatic positioning and assembly device for anti-loosening gaskets includes a feeding channel connected to a vibratory feeder, a support frame connected to the feeding channel, a conveying groove for conveying gaskets on the feeding channel, a first station and a second station on the feeding channel, the first station being located at the outlet end of the feeding channel, the second station being adjacent to the first station, a discharge hole and a positioning hole being opened on the feeding channel, both the discharge hole and the positioning hole communicating with the conveying groove, the discharge hole being located at the first station and penetrating the side wall of the outlet end of the feeding channel, and the positioning hole being located at the second station; The support frame is connected to a lifting cylinder, the drive shaft of the lifting cylinder is connected to a lifting plate, the lifting plate is connected to a material-picking cylinder and a mounting block, the drive shaft of the material-picking cylinder is connected to a material-picking rod, the material-picking rod is used to pass through the discharge hole and the center hole of the pad at the first station; the mounting block is connected to a positioning rod, when the material-picking rod passes through the pad at the first station, the positioning rod passes through the center hole of the pad at the second station, and the direction in which the material-picking cylinder drives the material-picking rod is parallel to the direction in which the feeding channel conveys the pad; The support frame is connected to a blocking device, which is used to prevent the blocking pad from disengaging from the outlet end of the conveying groove when the material taking cylinder is in an idle state. It also includes an assembly device, which includes a first moving component, a second moving component, and a clamping component. The first moving component and the second moving component are arranged vertically. The second moving component is connected to the first moving component. The clamping component is connected to the second moving component and is used to remove the gasket on the picking rod and transport it to the bolt.

[0007] By adopting the above technical solution, during use, the vibratory feeder transports the gasket to the conveying groove of the feeding channel, and the gasket reaches the first station after passing through the second station. When the picking cylinder is idle, the blocking device prevents the gasket from detaching from the outlet end of the conveying groove, ensuring a normal feeding rhythm. The lifting cylinder drives the lifting plate to move, allowing the picking rod to pass through the center hole of the gasket at the first station through the unloading hole, and the gasket is placed on the picking rod. At the same time, the positioning rod passes through the gasket at the second station to play a positioning role. The picking cylinder is activated, causing the picking rod to pull the gasket at the first station away from the feeding channel. Since the picking hole passes through the side wall of the feeding channel, the picking rod will not interfere with the feeding channel. Afterwards, the first and second moving components of the assembly device work together, and the clamping component removes the gasket from the picking rod and accurately transports and installs it onto the bolt, realizing the automatic positioning and assembly of the anti-loosening gasket, improving assembly efficiency and accuracy. At the same time, it realizes the full-process automation from gasket feeding to installation onto the bolt, improving the low efficiency and high labor intensity of traditional assembly methods.

[0008] Preferably, the outlet end of the feeding channel is connected to a photoelectric switch for detecting whether the pad at the first station has arrived. The photoelectric switch is connected to a control module, which is electrically connected to the lifting cylinder.

[0009] By adopting the above technical solution, photoelectric switches are used to detect whether the gasket at the first station has arrived. The control module controls the lifting cylinder according to the detection result, which can realize accurate detection of the gasket position and automatic control of the lifting cylinder, thereby improving the automation level and assembly accuracy of the anti-loosening gasket automatic positioning assembly device.

[0010] Preferably, the feeding channel is connected to a first Hall sensor and a second Hall sensor. The first Hall sensor and the second Hall sensor are symmetrically distributed at both ends of the first station along the gasket conveying direction to detect the position of the gasket on the first station. The first Hall sensor and the second Hall sensor are both fixedly connected to a mounting rod, which is fixedly connected to the top of the feeding channel. The first Hall sensor and the second Hall sensor are both electrically connected to the control module.

[0011] By adopting the above technical solution, the feeding channel is connected to a first Hall sensor and a second Hall sensor distributed at both ends along the conveying direction of the gasket at the first station. Based on the principle of electromagnetic induction, when the gasket passes by, it causes a change in the surrounding magnetic field. The first and second Hall sensors can detect this magnetic field change, thereby determining the position of the gasket at the first station. The Hall sensors are fixed to the top of the feeding channel by mounting rods and are electrically connected to the control module. The detected gasket position information is transmitted to the control module in real time, allowing the control module to precisely control subsequent related operations based on this information, improving the accuracy and efficiency of automatic positioning and assembly of the anti-loosening gaskets.

[0012] Preferably, an adjustment assembly is provided between the material-picking cylinder and the material-picking rod. The adjustment assembly includes a fixed block, an adjustment block, and a miniature electric push rod. The fixed block is fixedly connected to the material-picking cylinder. An adjustment groove is provided on the top of the fixed block. The adjustment block is located in the adjustment groove and is slidably connected to the fixed block. The material-picking rod is connected to the adjustment block. The miniature electric push rod is located inside the adjustment groove and is fixedly connected to the fixed block. The miniature electric push rod is also fixedly connected to the adjustment block. The miniature electric push rod is electrically connected to the control module. The control module is configured to drive the miniature electric push rod to adjust according to the position information of the first workstation pad detected by the first Hall sensor and the second Hall sensor, so that the center of the material-picking rod is aligned with the center hole of the pad.

[0013] By adopting the above technical solution, during use, the first Hall sensor and the second Hall sensor detect the position information of the first station pad and transmit it to the control module. The control module drives the miniature electric push rod according to the position information. The miniature electric push rod pushes the adjusting block to slide in the adjusting groove, thereby driving the picking rod to move, so that the center of the picking rod can be accurately aligned with the center hole of the pad, improving the accuracy and efficiency of picking.

[0014] Preferably, the blocking device includes a blocking cylinder and a blocking plate. The blocking cylinder is fixedly connected to the support frame, and the blocking plate is connected to the blocking cylinder. The blocking plate is used to selectively block the first station pad from leaving the feeding channel.

[0015] By adopting the above technical solution, a blocking device including a blocking cylinder and a blocking plate is set up. The blocking cylinder is fixedly connected to the support frame, and the blocking plate is connected to the blocking cylinder and can selectively block the first station pad from leaving the feeding channel. When the picking cylinder is idle, it can prevent the pad from falling off the outlet end of the conveying groove, ensuring normal feeding and operation of the device.

[0016] Preferably, the first moving component includes a base plate, a linear module, a guide rail, and a movable slider. The linear module and the guide rail are both horizontally arranged and fixedly connected to the base plate. The length direction of the guide rail is parallel to the length direction of the linear module. The guide rail is slidably connected to the movable slider. The movable slider and the slider of the linear module are both connected to the second moving component.

[0017] By adopting the above technical solution, the linear module and guide rail of the first moving component cooperate, and the moving slider on the guide rail and the slider on the linear module are connected to the second moving component. This can enhance the stability and accuracy of the movement of the second moving component, enabling the second moving component to move smoothly along a specific direction. This ensures that the clamping component can more accurately remove the pads from the picking rod and transport them to the bolts.

[0018] Preferably, the second moving component includes a fixed frame, an electric slide table, and a lifting frame. The fixed frame is connected to both the linear module and the moving slider. The electric slide table is connected to the fixed frame. The electric slide table is angled with the horizontal direction along its length. The lifting frame is connected to the slider of the electric slide table. The clamping component is connected to the lifting frame.

[0019] By adopting the above technical solution, the fixed frame is connected to the linear module and the movable slider, which allows the second movable component to move under the drive of the first movable component; the electric slide table is set at an angle between its length direction and the horizontal direction, which can realize multi-angle movement adjustment; the lifting frame is connected to the electric slide table slider and the clamping component is connected to the lifting frame, which can drive the clamping component to realize multi-angle movement and lifting, making it convenient to remove the pads on the picking rod and transport them to be installed on the bolts.

[0020] Preferably, the lifting frame extends to an edge portion, the clamping assembly is connected to the edge portion, and a clearance space is formed on one side of the clamping assembly. When the clamping assembly clamps the pad on the material picking rod, the feeding channel is located within the clearance space.

[0021] By adopting the above technical solution, the lifting frame extends to the edge and connects to the clamping component, so that a clearance space is formed on one side of the clamping component. This allows the feeding channel to be located within the clearance space when the clamping component clamps the pad on the picking rod, avoiding interference between the feeding channel and the clamping component during the clamping process, ensuring the smooth operation of the clamping operation, and improving the stability and reliability of the automatic positioning assembly device for anti-loosening pads.

[0022] Preferably, the clamping assembly includes a clamping cylinder, a first clamp, and a second clamp. The clamping cylinder is connected to the lifting frame. The first clamp and the second clamp are symmetrically distributed and connected to two drive shafts of the clamping cylinder for clamping the pad.

[0023] By adopting the above technical solution, the clamping cylinder connected to the lifting frame drives the symmetrically distributed first and second clamping jaws to clamp the gasket, which facilitates the removal of the gasket from the picking rod and its transportation and installation onto the bolt.

[0024] Preferably, the sidewalls of the first gripper and the second gripper that are close to each other are provided with gripping grooves, and the bottom of the gripping grooves is set with an arc.

[0025] By adopting the above technical solution, the curved clamping groove increases the contact area between the clamp and the pad, improves clamping stability, and ensures assembly accuracy and stability.

[0026] In summary, the present invention has the following beneficial effects: During operation, the vibratory feeder transports the gaskets to the conveying groove of the feeding channel. The gaskets then pass through the second station to reach the first station. When the picking cylinder is idle, the blocking device prevents the gaskets from detaching from the outlet end of the conveying groove, ensuring a normal feeding rhythm. The lifting cylinder drives the lifting plate to move, allowing the picking rod to pass through the feeding hole and through the center hole of the gasket at the first station, placing the gasket on the picking rod. Simultaneously, the positioning rod passes through the gasket at the second station for positioning. The picking cylinder is activated, causing the picking rod to pull the gasket at the first station away from the feeding channel. Since the picking hole penetrates the side wall of the feeding channel, the picking rod will not interfere with the feeding channel. Subsequently, the first and second moving components of the assembly device work together, and the clamping component removes the gasket from the picking rod and accurately transports and installs it onto the bolt, achieving automatic positioning and assembly of the anti-loosening gaskets, improving assembly efficiency and accuracy. Simultaneously, it automates the entire process from gasket feeding to bolt installation, improving the low efficiency and high labor intensity of traditional assembly methods.

[0039] An automatic positioning and assembly device for anti-loosening gaskets, referring to Figure 1 , Figure 2 and Figure 3 It includes a support frame 1, a feeding channel 2 connected to the vibratory feeder, a lifting cylinder 5, a picking cylinder 6, a mounting block 7, a blocking device 8, and an assembly device 9. The feeding channel 2 is fixedly connected to the support frame 1. The feeding channel 2 has a conveying groove 21, a first station 22, a second station 23, a discharge hole 24, and a positioning hole 25. The discharge hole 24 is located at the first station 22 and penetrates through the side wall of the outlet end. The positioning hole 25 is located at the second station 23.

[0040] Reference Figure 3 and Figure 4 The lifting cylinder 5 is connected to the support frame 1, and a lifting plate 51 is fixedly connected to the lifting cylinder 5. The picking cylinder 6 and the mounting block 7 are both fixedly connected to the lifting plate 51. The drive shaft of the picking cylinder 6 is connected to a picking rod 61, which passes through the discharge hole 24 and the center hole of the pad located at the first station 22. The mounting block 7 is fixedly connected to a positioning rod 71, which passes through the center hole of the pad located at the second station 23 when the picking rod 61 passes through the pad at the first station 22. The direction in which the picking cylinder 6 drives the picking rod 61 is parallel to the direction in which the feeding channel 2 conveys the pad. The blocking device 8 is connected to the support frame 1 and is used to block the pad from disengaging from the outlet end of the conveying groove 21 when the picking cylinder 6 is in an idle state. The assembly device 9 is used to remove the pad from the picking rod 61 and install it onto the bolt.

[0041] By coordinating the various components of the device, the anti-loosening gaskets are automatically positioned and assembled, realizing an automated process from feeding, picking up, positioning and installation of the anti-loosening gaskets from the vibratory feeder, improving assembly efficiency and accuracy, and reducing labor costs.

[0042] Reference Figure 3 The support frame 1 has a feeding trough 11 through which the outlet end of the vibratory feeder passes. A support block 12 is fixedly connected to the support frame 1, and the support block 12 is located at the bottom of the feeding trough 11. The outlet end of the vibratory feeder passes through the feeding trough 11 and is fixedly connected to the support block 12.

[0043] Reference Figure 2 , Figure 3 and Figure 4 The bottom of the feeding channel 2 is provided with a protrusion 201, which is fixedly connected to the side wall of the support block 12 by bolts. This design reduces the impact of the feeding channel 2 on the conveying groove 21 during installation. The inlet end of the feeding channel 2 is aligned with the outlet end of the vibratory feeder.

[0044] Reference Figure 2The width of the conveying groove 21 is slightly larger than the width of the gasket, and the height is slightly larger than the thickness of the gasket. For example, the width of the conveying groove 21 is 30mm and the height is 5mm; the width of the gasket is 28mm and the height is 4mm. This design ensures that the gaskets are conveyed one by one in the conveying groove 21, while also limiting the conveying direction of the gaskets.

[0045] Reference Figure 2 The first station 22 is located at the outlet end of the feeding channel 2, and the second station 23 is adjacent to the first station 22. Both the discharge hole 24 and the positioning hole 25 penetrate the feeding channel 2 and are connected to the conveying groove 21. The discharge hole 24 is located at the first station 22, and the positioning hole 25 is located at the second station 23. The axial distance between the discharge hole 24 and the positioning hole 25 is the distance between the center points of two adjacent gaskets. The diameters of both the discharge hole 24 and the positioning hole 25 are larger than the diameter of the center hole of the gasket and smaller than the outer contour width of the gasket.

[0046] Reference Figure 4 Both the positioning rod 71 and the picking rod 61 are columnar rod structures. The diameter of the feeding hole 24 is larger than the diameter of the picking rod 61, the diameter of the positioning hole 25 is larger than the diameter of the positioning rod 71, and the diameter of the positioning rod 71 is smaller than the diameter of the picking rod 61.

[0047] This structural design of the feeding channel 2 allows the anti-loosening pads to be picked up and positioned at the first station 22 and the second station 23 respectively. When the picking rod 61 passes through the pad at the first station 22, the positioning rod 71 passes through the pad at the second station 23. This ensures that adjacent pads maintain a stable position during the picking process and avoids mutual interference.

[0048] Reference Figure 5 and Figure 6 The top of the picking rod 61 is tapered, making it easier to insert the picking rod 61 into the center hole of the gasket and improving the success rate of picking up the material. The upper part of the picking rod 61 has a slot 611 for holding the gasket. The diameter of the lower part of the picking rod 61 is larger than the diameter of the center hole of the gasket, but smaller than the width of the outer contour of the gasket.

[0049] Reference Figure 1 and Figure 4 The lifting cylinder 5 and the lifting plate 51 are both located on the same side of the feeding channel 2, and the picking cylinder 6 is located below the feeding channel 2. The direction in which the picking cylinder 6 drives the picking rod 61 is parallel to the direction of the conveying pad in the feeding channel 2, both being horizontal.

[0050] Reference Figure 4Both the lifting cylinder 5 and the material handling cylinder 6 are sliding cylinders. The sliding table of the lifting cylinder 5 is fixedly connected to a limit block 52, and the support frame 1 is fixedly connected to a limit frame 53. The limit frame 53 is fixedly connected to a proximity switch 54 and is located above the limit block 52. The proximity switch 54 is electrically connected to the control module. When the proximity switch 54 detects that the limit block 52 is approaching, the control module controls the lifting cylinder 5 to stop.

[0051] Reference Figure 3 The blocking device 8 includes a blocking cylinder 81 and a blocking plate 82. The blocking cylinder 81 is horizontally positioned on the side of the feeding channel 2 away from the lifting cylinder 5 and is fixedly connected to the support frame 1. The blocking plate 82 is fixedly connected to the blocking cylinder 81 and is used to selectively block the pad of the first station 22 from leaving the feeding channel 2.

[0052] When the picking cylinder 6 is idle, the blocking cylinder 81 drives the blocking plate 82 to extend, preventing the gasket from detaching from the outlet end of the conveying groove 21; when the picking cylinder 6 starts working, the blocking plate 82 retracts, allowing the gasket to be picked up smoothly.

[0053] Reference Figure 4 A mounting base 31 is fixedly connected to the top outlet end of the feeding channel 2, and the mounting base 31 is located above the second station 23. The side wall of the mounting base 31 near the first station 22 is set as an inclined surface, and a photoelectric switch 3 is fixedly connected to the inclined surface to detect whether the pad of the first station 22 has arrived. The photoelectric switch 3 can be a diffuse reflection photoelectric switch 3 or a through-beam photoelectric switch 3.

[0054] Reference Figure 4 The photoelectric switch 3 is connected to a control module, which can be a PLC controller or a microcontroller. The control module is electrically connected to the lifting cylinder 5. When the photoelectric switch 3 detects that the pad has reached the preset position, the control module will promptly control the lifting cylinder 5 to operate, achieving more precise material handling.

[0055] With the cooperation of photoelectric switch 3 and control module, the position of the gasket can be detected in real time and the lifting cylinder 5 can be controlled in time, avoiding material picking failure caused by the gasket not reaching the first station 22, and further improving the assembly accuracy and efficiency.

[0056] Reference Figure 2The feeding channel 2 is connected to a first Hall sensor 41 and a second Hall sensor 42, both of which are linear Hall sensors. The first Hall sensor 41 and the second Hall sensor 42 are symmetrically distributed at both ends of the first station 22 along the gasket conveying direction, used to detect the position of the gasket on the first station 22. Both the first Hall sensor 41 and the second Hall sensor 42 are fixedly connected to a mounting rod 4, which is fixedly connected to the top of the feeding channel 2. Both the first Hall sensor 41 and the second Hall sensor 42 are electrically connected to the control module.

[0057] Reference Figure 2 The magnetic fields of the first Hall sensor 41 and the second Hall sensor 42 are symmetrically distributed: When the pad is centered, its distance to the first Hall sensor 41 and the second Hall sensor 42 is equal, so the magnetic field strength sensed by the two sensors is theoretically equal, and the output voltage V1≈V2. When the pad shifts to the left (closer to the first Hall sensor 41), the magnetic field at the first Hall sensor 41 becomes stronger (V1 increases), and the magnetic field at S2 becomes weaker (V2 decreases). When the shim shifts to the right (closer to S2), the opposite occurs: V1 decreases and V2 increases.

[0058] Reference Figure 2 The distance between the first Hall sensor 41 and the second Hall sensor 42 is smaller than the outer diameter of the gasket, but larger than the diameter of the central hole, to ensure that the gasket can simultaneously affect the first Hall sensor 41 and the second Hall sensor 42 within any expected offset range.

[0059] Even if there are slight differences in the magnetic strength of different pads, as long as they are symmetrically magnetized with respect to the first Hall sensor 41 and the second Hall sensor 42, the zero point of the differential signal will remain stable.

[0060] Reference Figure 5 When the picking rod 61 passes through the center hole of the pad at the first station 22, the top of the picking rod 61 is lower than the second Hall sensor 42 to prevent interference during the picking process.

[0061] Reference Figure 6 An adjusting assembly 62 is provided between the material-picking cylinder 6 and the material-picking rod 61. The adjusting assembly 62 includes a fixed block 621, an adjusting block 622, and a miniature electric push rod 623. The fixed block 621 is fixedly connected to the material-picking cylinder 6. The top of the fixed block 621 has an adjusting groove 6211, which can be a dovetail groove or a T-shaped groove. The adjusting block 622 matches the adjusting groove 6211 and is located within the adjusting groove 6211, and is slidably connected to the fixed block 621. The material-picking rod 61 is fixedly connected to the adjusting block 622.

[0062] Reference Figure 6 Two miniature electric push rods 623 are provided, spaced apart inside the adjusting groove 6211, and fixedly connected to the fixing block 621. Both ends of the adjusting block 622 are fixedly connected to the adjacent miniature electric push rods 623. The miniature electric push rods 623 are electrically connected to the control module, which is configured to drive the miniature electric push rods 623 to adjust according to the position information of the pad at the first station 22 detected by the Hall sensor, so that the center of the picking rod 61 is aligned with the center hole of the pad.

[0063] The first Hall sensor 41 and the second Hall sensor 42 can accurately detect the position of the gasket. The control module controls the micro electric push rod 623 to adjust the position of the picking rod 61 according to the detection information, so that the center of the picking rod 61 is aligned with the center hole of the gasket, which improves the accuracy of picking, reduces assembly problems caused by the deviation of the picking position, and further improves the performance of the entire assembly device 9.

[0064] Reference Figure 7 The assembly device 9 includes a first moving component 91, a second moving component 92, and a clamping component 93. The first moving component 91 and the second moving component 92 are arranged vertically. The second moving component 92 is connected to the first moving component 91. The clamping component 93 is connected to the second moving component 92 and is used to remove the gasket on the picking rod 61 and transport it to the bolt.

[0065] Reference Figure 7 The first moving component 91 includes a base plate 911, a linear module 912, a guide rail 913, and a sliding block 914. The linear module 912 can be a ball screw linear module 912 or a synchronous belt linear module 912. Both the guide rail 913 and the linear module 912 are horizontally arranged and fixedly connected to the base plate 911, with the length direction of the guide rail 913 parallel to the length direction of the linear module 912. The sliding block 914 is slidably connected to the guide rail 913. Both the sliding block 914 and the slider of the linear module 912 are connected to the second moving component 92. This structure enables the first moving component 91 to achieve linear movement in the horizontal direction.

[0066] Reference Figure 7 The second moving component 92 includes a fixed frame 921, an electric slide 922, and a lifting frame 923. The fixed frame 921 is a metal frame. The electric slide 922 is a servo electric slide 922. The electric slide 922 is vertically set and fixedly connected to the fixed frame 921. The lifting frame 923 is fixedly connected to the slider of the electric slide 922.

[0067] Reference Figure 7It includes multiple slotted photoelectric switches. The lifting frame 923 is fixedly connected to the baffles of the slotted photoelectric switches, and both ends of the electric slide table 922 are fixedly connected to the detection slots of the slotted photoelectric switches. The fixed frame 921 is fixedly connected to the baffles of the slotted photoelectric switches, and both ends of the linear module 912 are fixedly connected to the detection slots of the slotted photoelectric switches.

[0068] Reference Figure 7 The lifting frame 923 extends with an edge portion, and the clamping assembly 93 is fixedly connected to the edge portion. A clearance space is formed on one side of the clamping assembly 93. When the clamping assembly 93 clamps the pad on the picking rod 61, the feeding channel 2 is located within the clearance space.

[0069] The clearance space design ensures that the clamping component 93 will not interfere with the feeding channel 2 when clamping the pad, thus ensuring the smoothness of the assembly process and improving the overall assembly efficiency.

[0070] Reference Figure 7 and Figure 8 The clamping assembly 93 includes a clamping cylinder 931, a first gripper 932, and a second gripper 933. The clamping cylinder 931 is a finger cylinder. The first gripper 932 and the second gripper 933 are symmetrically distributed and fixedly connected to the two drive shafts of the clamping cylinder 931, respectively, for clamping the pad. Both the first gripper 932 and the second gripper 933 have mounting grooves 9301, and the drive shafts of the clamping cylinder 931 are located within the corresponding mounting grooves 9301. Both the first gripper 932 and the second gripper 933 are fixed to the clamping cylinder 931 by bolts.

[0071] Reference Figure 8 The first gripper 932 and the second gripper 933 are provided with gripping grooves 9302 on their sidewalls that are close to each other. The bottom of the gripping groove 9302 is set with an arc. This arc setting can better fit the shape of the pad and improve the stability of the gripping.

[0072] The implementation principle of this embodiment is as follows: After the vibratory feeder arranges the anti-loosening pads neatly, it conveys them into the conveying groove 21 of the feeding channel 2. The pads move to the second station 23 and the first station 22 within the conveying groove 21. When the pad reaches the first station 22, the photoelectric switch 3 detects the arrival of the pad, and the control module controls the lifting cylinder 5 to move, causing the lifting plate 51 to rise, which in turn drives the picking cylinder 6 to rise, so that the picking rod 61 passes through the unloading hole 24 and inserts into the center hole of the pad at the first station 22. At the same time, the positioning rod 71 passes through the pad at the second station 23 for positioning. When the pad is placed on the picking rod 61, the blocking plate 82 of the blocking device 8 retracts, allowing the pad to be removed. The first moving component 91 and the second moving component 92 of the assembly device 9 work together to move the clamping component 93 to the picking rod 61. The clamping cylinder 931 of the clamping component 93 drives the first jaw 932 and the second jaw 933 to close, clamping the pad on the picking rod 61. Next, assembly device 9 transports the gasket to the bolt location for installation. The entire process achieves automatic positioning and assembly of the anti-loosening gasket, improving assembly efficiency and accuracy, reducing labor costs, and representing a significant improvement over traditional assembly methods. Furthermore, the device has a compact layout, avoiding space waste and mechanical interference.

[0073] After the gasket is removed from the feeding channel 2, the blocking cylinder 81 immediately drives the blocking plate 82 to extend and block the outlet end of the feeding channel 2. Then, the lifting cylinder 5 descends and waits for the next start signal from the photoelectric switch.

Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
