Description
Technical Field
[0001] This application relates to the field of wheel speed sensor assembly technology, and more specifically, to an automatic assembly device for a wheel speed sensor frame. Background Technology
[0002] Wheel speed sensors, as key components in automotive electronic control systems, are widely used in important modules such as anti-lock braking systems (ABS), traction control systems (TCS), and electronic stability control systems (ESP). One of their core structural components is the frame assembly, typically composed of magnets, plastic terminals, and a metal housing. The assembly precision directly affects the sensor's signal acquisition accuracy and operational stability. With the automotive industry's ever-increasing demands for component quality, traditional manual assembly methods are no longer sufficient to meet the needs of high-volume, high-precision production. Automated assembly equipment is gradually becoming the mainstream trend in the industry.
[0003] Currently, there are still many technical challenges in the assembly process of wheel speed sensor frames. For example, the small size and complex shape of plastic terminals make them prone to jamming and misalignment with traditional conveying methods. Magnets, due to their strong magnetism, are susceptible to unstable adsorption or misalignment during conveying and assembly, affecting overall assembly efficiency and consistency. Furthermore, most existing assembly devices still rely on manual adjustment for material supply, which is not only labor-intensive but also prone to increasing product defect rates due to human error, affecting product quality stability.
[0004] In response to the above problems, some technical solutions for automatic assembly devices have been proposed in the industry. However, they generally suffer from problems such as unreasonable structural design, low feeding accuracy, and poor adaptability. In particular, the lack of effective limiting and guiding structures in the plastic terminal feeding process leads to instability in the conveying process, affecting the subsequent assembly cycle and success rate. Summary of the Invention
[0005] An automatic assembly device for a wheel speed sensor frame according to an embodiment of this application includes an assembly table. An assembly mechanism for carrying the workpiece to be assembled is rotatably mounted on the assembly table. A magnet feeding mechanism is provided on the assembly table on one side of the assembly mechanism to provide the magnetic components required for the wheel speed sensor frame. A plastic terminal feeding mechanism is provided on the assembly table on the other side of the assembly mechanism to provide the corresponding plastic terminals. The magnet feeding mechanism and the plastic terminal feeding mechanism are respectively equipped with a second feeding component and a first feeding component. The first feeding component is used to accurately convey the plastic terminals to the assembly station of the assembly mechanism, and the second feeding component is used to convey the magnets to the corresponding assembly position.
[0006] Furthermore, the plastic terminal feeding mechanism includes a base fixedly installed on the assembly table. The upper end of the base is provided with a feeding rail for guiding the plastic terminals to be conveyed along a predetermined trajectory. The feeding end of the feeding rail is connected to the discharging end of the conveyor belt. The conveyor belt is fixedly installed on one side of the assembly table for conveying the plastic terminals sequentially into the feeding rail.
[0007] Furthermore, a top frame is fixedly installed above the material conveying rail, and a third cylinder is installed on the top frame. The piston rod of the third cylinder passes through the top frame and is connected to the U-shaped plate. The U-shaped plate is located directly above the material conveying rail and is used to limit the upper end of the plastic terminal.
[0008] Furthermore, the first feeding assembly and the second feeding assembly adopt the same structural design. The first feeding assembly includes a fixed base fixedly installed on the assembly table. A rotary cylinder is provided on one side of the fixed base. The rotary cylinder drives the second turntable to rotate. The edge of the second turntable is provided with a material groove for receiving materials, so as to realize the transfer of plastic terminals.
[0009] Furthermore, a fourth cylinder is embedded inside the second turntable. The piston rod of the fourth cylinder extends into the material groove and is connected to the pusher plate. When the second turntable rotates to the designated position, the fourth cylinder drives the pusher plate to push out the plastic terminal in the material groove and send it into the assembly station.
[0010] Furthermore, the magnet feeding mechanism includes a bracket fixedly installed on the assembly table. A plurality of parallel guide rails are provided on one side of the bracket. A discharge plate is slidably installed on the guide rails. A plurality of vertically arranged conveying pipes are provided inside the discharge plate. The upper end of the conveying pipe is the inlet and the lower end is the outlet. The discharge plate is driven by a first cylinder to move along the guide rails.
[0011] Furthermore, the bottom of the discharge plate is slidably disposed inside the sealing plate, and the sealing plate is fixedly installed at the guide rail to seal the discharge port of the conveying pipe.
[0012] Furthermore, the assembly mechanism includes a first turntable rotatably mounted on the assembly table. The first turntable is driven to rotate by a motor. Multiple assembly plates are evenly distributed in the circumferential direction of the first turntable, and each assembly plate is provided with an assembly slot for accommodating the skeleton to be assembled.
[0013] Furthermore, a mounting base is provided near each assembly plate on the first turntable. A second cylinder is mounted on the mounting base, and a pressure plate is connected to the piston rod of the second cylinder. When the plastic terminal is fed into the assembly slot, the second cylinder drives the pressure plate to move downward and press the plastic terminal firmly.
[0014] Furthermore, the assembly slot rotates with the first turntable and corresponds sequentially to the outlets of the first feeding assembly and the second feeding assembly, respectively receiving plastic terminals and magnets.
[0015] 1. The beneficial effects of this application are as follows: By setting up an assembly table, a rotating assembly mechanism, a magnet feeding mechanism, and a plastic terminal feeding mechanism, and cooperating with the feeding component, automatic material conveying and precise assembly are achieved. The overall structural design is reasonable and highly automated, which can effectively replace the traditional assembly method that relies on manual operation, significantly improving assembly efficiency and production cycle time. At the same time, the coordinated design of the material conveying rail, conveyor belt, U-shaped plate, and cylinder in the plastic terminal feeding mechanism ensures the stability and positioning accuracy of material conveying. Combined with the rotary cylinder, turntable, and pushing structure in the feeding component, accurate placement of plastic terminals is achieved. The magnet feeding mechanism also ensures the orderly supply of magnets through the material conveying pipe and pneumatic drive components. The linkage and coordination between the various components make the entire assembly process efficient, stable, and controllable. This device effectively reduces the manual intervention links, avoids the errors and instability caused by human operation, and greatly improves assembly efficiency and production cycle time.
[0016] 2. The beneficial effects of this application are as follows: A third cylinder is provided on the top frame, and its drive end is connected to a U-shaped plate. The position of the U-shaped plate can be adjusted according to the height of the plastic terminals to adapt to materials of different specifications. During the conveying process, the U-shaped plate limits the top of the plastic terminals, effectively preventing upward squeezing caused by material accumulation or congestion; at the same time, the two sides of the U-shaped plate form a shield to protect the plastic terminals, preventing them from shifting or falling during the conveying process, thereby further improving the control accuracy and stability of the plastic terminal conveying process.

[0033] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.
[0034] The following describes an automatic assembly device for a wheel speed sensor frame according to an embodiment of this application, with reference to the accompanying drawings.
[0035] like Figures 1-9 As shown, an automatic assembly device for a wheel speed sensor frame according to an embodiment of this application includes an assembly table 1, on which an assembly mechanism 3 for carrying the workpiece to be assembled is rotatably mounted.
[0036] A magnet feeding mechanism 2 is provided on the assembly table 1 on one side of the assembly mechanism 3. It is used to provide the magnetic components required for the wheel speed sensor frame. The magnet feeding mechanism 2 includes a bracket 21 fixedly installed on the assembly table 1. A plurality of parallel guide rails 22 are provided on one side of the bracket 21. A discharge plate 23 is slidably installed on the guide rails 22. A plurality of vertically arranged conveying pipes 24 are provided inside the discharge plate 23. The upper end of the conveying pipe 24 is the inlet and the lower end is the outlet, which is used to accommodate and guide the magnetic components to move downward in sequence.
[0037] The magnetic element can be placed vertically inside the feeding pipe 24. The magnetic element can be discharged from the outlet. The discharge plate 23 is driven by the first cylinder 26 to move along the guide rail 22. When the magnetic element in the front feeding pipe 24 is removed, the discharge plate 23 can be driven by the first cylinder 26 to move along the guide rail 22, and the unused feeding pipe 24 can be switched to the feeding position to achieve continuous feeding.
[0038] Furthermore, the bottom of the discharge plate 23 is slidably disposed within the sealing plate 25, and the sealing plate 25 is fixedly installed at the guide rail 22 to seal the discharge port of the conveying pipe 24 to prevent the magnet from falling off accidentally. When the discharge plate 23 moves, the corresponding conveying pipe 24 disengages from the sealing area of the sealing plate 25, facilitating the smooth discharge of the magnetic component.
[0039] like Figure 3 As shown, a plastic terminal feeding mechanism 4 is provided on the assembly table 1 on the other side of the assembly mechanism 3 to provide corresponding plastic terminals. The plastic terminal feeding mechanism 4 includes a base 41 fixedly installed on the assembly table 1. A conveying rail 42 is provided at the upper end of the base 41 to guide the plastic terminals to be conveyed along a predetermined trajectory. The inlet end of the conveying rail 42 is connected to the outlet end of the conveyor belt 46. The conveyor belt 46 is fixedly installed on one side of the assembly table 1 to convey the plastic terminals to the conveying rail 42 in sequence.
[0040] like Figure 4 As shown, a top frame 43 is fixedly installed above the conveying rail 42. A third cylinder 45 is installed on the top frame 43. The piston rod of the third cylinder 45 passes through the top frame 43 and is connected to the U-shaped plate 44. The U-shaped plate 44 is located directly above the conveying rail 42 and is used to limit the upper end of the plastic terminal. When the third cylinder 45 moves the U-shaped plate 44 to a suitable position, on the one hand, the two sides of the U-shaped plate 44 protect the plastic terminal located inside the conveying rail 42 to prevent it from shifting or falling during the conveying process. On the other hand, the upper end of the U-shaped plate 44 limits the upper end of the plastic terminal, effectively preventing upward squeezing caused by material accumulation or congestion, thereby improving the control accuracy and stability of the conveying process.
[0041] like Figure 1 and Figure 2As shown, the magnet feeding mechanism 2 and the plastic terminal feeding mechanism 4 are respectively equipped with a second feeding component 6 and a first feeding component 5. The first feeding component 5 is used to accurately transport the plastic terminal to the assembly station of the assembly mechanism 3, while the second feeding component 6 is used to transport the magnet to the corresponding assembly position.
[0042] Specifically, the first feeding assembly 5 and the second feeding assembly 6 adopt the same structural design. The first feeding assembly 5 includes a fixed base 51 fixedly installed on the assembly table 1. A rotary cylinder 52 is provided on one side of the fixed base 51. The rotary cylinder 52 drives the second turntable 53 to rotate. The edge of the second turntable 53 is provided with a material groove 54 for receiving materials to realize the transfer of plastic terminals. When the rotary cylinder 52 causes the second turntable 53 to rotate, so that the material groove 54 corresponds to the outlet of the conveying rail 42, the plastic terminal enters the material groove 54 by being pushed by other terminals on the rear side. At this time, the rotary cylinder 52 causes the second turntable 53 to rotate again, so that the material groove 54 corresponds to the feeding area of the assembly mechanism 3.
[0043] Since the second turntable 53 is equipped with a fourth cylinder 55, the piston rod of the fourth cylinder 55 extends into the material groove 54 and is connected to the pusher plate 56. When the second turntable 53 rotates to the designated position, the fourth cylinder 55 drives the pusher plate 56 to push out the plastic terminal in the material groove 54 and send it into the assembly station of the assembly mechanism 3.
[0044] The operation of the second feeding component 6 is the same as that of the first feeding component 5. The magnetic element is pushed into the plastic terminal through the above operation to complete the assembly.
[0045] Figure 5 and Figure 6 As shown, the assembly mechanism 3 includes a first turntable 31 rotatably mounted on the assembly table 1. The first turntable 31 is driven to rotate by a motor. Multiple assembly plates 32 are evenly distributed in the circumferential direction of the first turntable 31. Each assembly plate 32 has an assembly slot 33 for accommodating the skeleton to be assembled. The plastic terminal is first pushed into the assembly slot 33. Then the first turntable 31 rotates, so that the assembly slot 33 passes through the magnet feeding station in sequence, so that the second feeding component 6 pushes the magnet into the plastic terminal to complete the final assembly.
[0046] Furthermore, a mounting base 34 is provided on the first turntable 31 near each assembly plate 32. A second cylinder 35 is mounted on the mounting base 34. The piston rod of the second cylinder 35 is connected to a pressure plate 36. When the plastic terminal is fed into the assembly slot 33, the second cylinder 35 drives the pressure plate 36 to move downward, pressing and fixing the plastic terminal to ensure its stability during subsequent magnet assembly and avoid misalignment caused by vibration or impact.
[0047] To ensure automated operation of the entire assembly process and coordinated operation between components, this device is also equipped with a controller to uniformly control the sequence and time intervals of action of various actuators such as cylinders, motors, and rotary cylinder 52. In addition, sensors are installed at key locations to detect the position of components, whether materials are in place, and whether actions are completed, thereby ensuring the accuracy and reliability of the entire assembly process.
[0048] In summary, before assembly begins, magnets and plastic terminals are placed manually or automatically into the feeding pipe 24 of the magnet feeding mechanism 2 and onto the conveyor belt 46, respectively. The conveyor belt 46 sequentially transports the plastic terminals to the feeding rail 42. The feeding rail 42 guides the plastic terminals forward along a predetermined trajectory. The third cylinder 45 drives the U-shaped plate 44 to move downward, limiting the top of the plastic terminals in the feeding rail 42. The U-shaped plate 44 prevents the terminals from shifting or falling during transport. The plastic terminals reach the feeding rail 42. After the end, it enters the material trough 54 of the first feeding assembly 5. The material trough 54 is located at the edge of the second turntable 53. The second turntable 53 is rotated by the rotary cylinder 52, so that the material trough 54 is aligned with the discharge port of the conveying rail 42, causing the plastic terminal to enter the material trough 54. The rotary cylinder 52 drives the second turntable 53 to rotate a certain angle, so that the material trough 54 containing the plastic terminal moves to the assembly slot 33. At this time, the fourth cylinder 55 is started, pushing the pusher plate 56 to push out the plastic terminal in the material trough 54 and send it into the assembly slot 33.
[0049] The second cylinder 35 on the mounting base 34 drives the pressure plate 36 to move downward, pressing and fixing the plastic terminal into the assembly slot 33. At the same time, the first turntable 31 rotates, causing the assembly slot 33 containing the plastic terminal to be rotated to the second feeding component 6. After the second feeding component 6 picks up the material, the second turntable 53 of the second feeding component 6 rotates into place. The fourth cylinder 55 drives the pusher plate 56 to move, pushing the magnet into the fixed plastic terminal to complete the assembly. All actions are uniformly scheduled by the controller. Sensors are installed at each key position to detect the material status and component position.
