Description

Technical Field

[0001] This invention belongs to the field of displacement sensor technology, specifically relating to an assembly device and method for a modular displacement sensor. Background Technology

[0002] Modular displacement sensors are flexible and scalable displacement sensors, typically used to measure physical quantities such as object position, distance, and displacement. Unlike traditional single-design displacement sensors, modular displacement sensors consist of multiple functional modules, each of which can be used independently or combined as needed, thus providing more customization options and flexibility. Existing technologies typically use linear automated assembly equipment to assemble modular displacement sensors. A linear conveyor platform transports the modular displacement sensor housing to be assembled, allowing a robotic arm to assemble it as the housing moves. However, since modular displacement sensors require the assembly of multiple modules, linear automated assembly equipment occupies a large space and is inconvenient to use. Furthermore, modular displacement sensors are prone to misalignment during transport on the linear conveyor platform, affecting assembly quality.

[0003] To address the aforementioned issues, this application proposes an assembly device and method for a modular displacement sensor. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides an assembly device and method for a modular displacement sensor, which features a small footprint and ease of use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an assembly device for a modular displacement sensor, comprising a base, wherein a conveying structure is provided on the top surface of the base;

[0006] The conveying structure includes a frame, which is fixedly connected to the top surface of the base. A conveyor belt is slidably connected to the inner wall of the frame. A toothed block assembly is fixedly connected to the inner wall at the bottom of the conveyor belt. The base has an installation groove near any inner corner of the conveyor belt. A drive motor is installed in the installation groove. A transmission tooth is fixedly connected to the output shaft of the drive motor. The transmission tooth meshes with the toothed block assembly. The conveyor belt is connected to the transmission tooth via the toothed block assembly. Several placement structures are equidistantly arranged on the top surface of the conveyor belt.

[0007] As a preferred assembly device for a modular displacement sensor of the present invention, the placement structure includes a first connecting column, which is fixedly connected to the top surface of the frame. A fixing plate is fixedly connected to the top of the first connecting column, and a second connecting column is fixedly connected to the center of the top surface of the fixing plate. A placement plate is fixedly connected to the top of the second connecting column.

[0008] As a preferred assembly device for a modular displacement sensor of the present invention, the placement plate has four guide openings arranged in a ring, and each guide opening is slidably connected to a limiting post, the top of which is a sloping structure.

[0009] As a preferred assembly device for a modular displacement sensor of the present invention, each of the limiting posts is fixedly connected to a first connecting plate at its bottom end, each of the first connecting plates is fixedly connected to a spring on the side away from the second connecting post, each of the springs is fixedly connected to a second connecting plate at the end away from the first connecting plate, each of the second connecting plates is fixedly connected to the bottom surface of the placement plate at its top end, and each of the second connecting plates is fixedly connected to the outer wall of the fixing plate at its bottom end.

[0010] As a preferred assembly device for a modular displacement sensor of the present invention, a collar is rotatably connected to the outer wall of the second connecting column, and a guide plate is fixedly connected to each collar near the position of the first connecting plate. The end of each guide plate near the collar is disposed between the collar and the adjacent first connecting plate.

[0011] As a preferred assembly device for a modular displacement sensor of the present invention, a connecting rod is fixedly connected to the bottom surface of the collar, and a handle is fixedly connected to the bottom end of the connecting rod.

[0012] As a preferred assembly device for a modular displacement sensor of the present invention, a connecting frame is fixedly connected to the top position of the outer wall of the frame, and a protective shell is fixedly connected to the top surface of the connecting frame.

[0013] As a preferred assembly device for a modular displacement sensor of the present invention, an assembly structure is provided on the top surface of the base;

[0014] The assembly structure includes a mounting plate, with support rods fixedly connected to the four corners of the bottom surface of the mounting plate. The support rods are fixedly connected to the top surface of the base, and several robotic arms are mounted on the top surface of the mounting plate.

[0015] As a preferred assembly device for a modular displacement sensor of the present invention, a mounting bracket is fixedly connected to the top surface of the mounting plate at a position away from the robotic arm, and a blower is mounted on the mounting bracket.

[0016] An assembly method for a modular displacement sensor assembly device includes the following specific steps:

[0017] S1. Start the drive motor through the PLC program, so that the drive motor drives the transmission gear to rotate. When the transmission gear rotates, it will drive the conveyor belt to move on the frame, so that the conveyor belt drives the placement structure on the conveyor belt to perform a circular rotation. Under the control of the PLC program, the drive motor will temporarily stop when the placement structure moves to the position of the robotic arm, so as to provide assembly time for the modular displacement sensor.

[0018] S2. Then, the staff places the housing of the modular displacement sensor to be assembled on the shelf near the blower, so that the limiting post moves in the guide port and away from the center of the shelf. When the limiting post moves, it will drive the first connecting plate to move together, so that the spring changes from a relaxed state to a compressed state. Under the action of the spring, the limiting post positions and clamps the housing of the modular displacement sensor, so that the housing of the modular displacement sensor is in the center of the shelf, preventing the housing of the modular displacement sensor from moving and ensuring the quality of assembly.

[0019] S3. The modular displacement sensor housing on the shelf will rotate in a circular motion. When the modular displacement sensor housing moves to the position of the hair dryer, the hair dryer will start to blow away the dust and impurities inside the modular displacement sensor housing.

[0020] S4. When the modular displacement sensor housing on the shelf moves to the position of each robotic arm, multiple robotic arms will assemble the modular displacement sensor according to the assembly process of the modular displacement sensor.

[0021] S5. After assembly, the modular displacement sensor will be moved to the position where the modular displacement sensor housing is placed. The operator can use the handle to rotate the collar, which will move the guide plate. Under the action of the guide plate, the first connecting plate will move the limiting post within the guide opening, so that the limiting post will no longer clamp the modular displacement sensor. This makes it convenient for the operator to take out the modular displacement sensor and place the modular displacement sensor housing to be assembled, thus realizing the assembly of the modular displacement sensor.

[0022] Compared with the prior art, the beneficial effects of this invention are as follows: The addition of a conveyor structure allows for the use of transmission teeth and tooth block assemblies. A PLC program starts the drive motor, causing the drive motor to rotate the transmission teeth. When the transmission teeth rotate, they move the conveyor belt along the frame, causing the conveyor belt to rotate the storage structure on it in a circular motion. Under the control of the PLC program, the drive motor temporarily stops when the storage structure reaches the position of the robotic arm, providing assembly time for the modular displacement sensor. This eliminates the need for a long linear conveyor platform to assemble multiple modules, resulting in a smaller footprint and easier use. Furthermore, the addition of the storage structure allows for easier operation by the staff. The housing of the modular displacement sensor to be assembled can be placed on the mounting plate, allowing the limiting post to move within the guide port and away from the center of the mounting plate. As the limiting post moves, it also moves the first connecting plate, causing the spring to change from a relaxed state to a compressed state. Under the action of the spring, the limiting post positions and clamps the housing of the modular displacement sensor, ensuring it is centered on the mounting plate and preventing it from moving freely. This ensures assembly quality. When used in conjunction with a conveyor structure, the housing of the modular displacement sensor can be precisely moved to the assembly position of each assembly arm, facilitating the assembly of the modular displacement sensor.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] like Figures 1 to 5 As shown;

[0040] To achieve a small footprint and convenient use, this modular displacement sensor assembly device includes a base 1, and a conveying structure 2 is provided on the top surface of the base 1.

[0041] The conveying structure 2 includes a frame 21, which is fixedly connected to the top surface of the base 1. A conveyor belt 22 is slidably connected to the inner wall of the frame 21. A toothed block assembly 23 is fixedly connected to the inner wall at the bottom of the conveyor belt 22. An installation groove 24 is provided at any inner corner of the base 1 near the conveyor belt 22. A drive motor 25 is installed in the installation groove 24. A transmission tooth 26 is fixedly connected to the output shaft of the drive motor 25. The transmission tooth 26 meshes with the toothed block assembly 23. The conveyor belt 22 is connected to the transmission tooth 26 through the toothed block assembly 23. Several placement structures 3 are equidistantly arranged on the top surface of the conveyor belt 22.

[0042] In this implementation scheme: the drive motor 25 is a servo motor. The drive motor 25 is started by the PLC program, which drives the transmission gear 26 to rotate. When the transmission gear 26 rotates, it drives the conveyor belt 22 to move on the frame 21, thereby causing the conveyor belt 22 to drive the placement structure 3 on the conveyor belt 22 to perform a circular rotation. Under the control of the PLC program, the drive motor 25 is temporarily stopped when the placement structure 3 moves to the position of the robotic arm 43, which provides assembly time for the modular displacement sensor. The assembly of multiple modules can be realized without a long linear conveyor platform, which has a small footprint and is convenient to use.

[0043] Furthermore:

[0044] like Figures 6 to 8 As shown;

[0045] Based on the above:

[0046] In an optional embodiment, the placement structure 3 includes a first connecting column 31, which is fixedly connected to the top surface of the frame 21. A fixing plate 32 is fixedly connected to the top of the first connecting column 31. A second connecting column 33 is fixedly connected to the center of the top surface of the fixing plate 32. A placement plate 34 is fixedly connected to the top of the second connecting column 33. The placement plate 34 has four guide openings 35 arranged in a ring. A limit post 36 is slidably connected in each guide opening 35. The top of each limit post 36 has a sloping structure. A first connecting plate 37 is fixedly connected to the bottom of each limit post 36. A spring 38 is fixedly connected to the side of each first connecting plate 37 away from the second connecting column 33. A second connecting plate 39 is fixedly connected to the end of each spring 38 away from the first connecting plate 37. The top of each second connecting plate 39 is fixedly connected to the bottom surface of the placement plate 34. The bottom of each second connecting plate 39 is fixedly connected to the outer wall of the fixing plate 32.

[0047] In this embodiment: During use, the operator places the housing of the modular displacement sensor to be assembled on the placement plate 34, causing the limiting post 36 to move within the guide port 35 and away from the center of the placement plate 34. Since the tops of the limiting posts 36 are all sloping, it facilitates the placement of the modular displacement sensor housing. Furthermore, as the limiting post 36 moves, it causes the first connecting plate 37 to move as well, causing the spring 38 to change from a relaxed state to a compressed state. Under the action of the spring 38, the limiting post 36 positions and clamps the housing of the modular displacement sensor, ensuring that the housing is centered on the placement plate 34, preventing movement of the housing and ensuring assembly quality.

[0048] Furthermore:

[0049] like Figure 7 and Figure 8 As shown;

[0050] Based on the above:

[0051] To facilitate the handling of the modular displacement sensor by staff, in an optional embodiment, a collar 310 is rotatably connected to the outer wall of the second connecting column 33. A guide plate 311 is fixedly connected to each collar 310 near the first connecting plate 37. The end of each guide plate 311 near the collar 310 is located between the collar 310 and the nearby first connecting plate 37. A connecting rod 312 is fixedly connected to the bottom surface of the collar 310, and a handle 313 is fixedly connected to the bottom end of the connecting rod 312.

[0052] In this embodiment: After the modular displacement sensor is assembled, the operator can use the handle 313 to rotate the collar 310, so that the collar 310 drives the guide plate 311 to move. Under the action of the guide plate 311, the first connecting plate 37 drives the limiting post 36 to move within the guide opening 35, so that the limiting post 36 no longer clamps the modular displacement sensor, making it convenient for the operator to take out the modular displacement sensor and place the modular displacement sensor shell to be assembled.

[0053] Furthermore:

[0054] like Figures 3 to 5 As shown;

[0055] Based on the above:

[0056] To improve the stability of the assembly device, in an optional embodiment, a connecting frame 27 is fixedly connected to the top of the outer wall of the frame 21, and a protective shell 28 is fixedly connected to the top surface of the connecting frame 27.

[0057] In this embodiment, the protective shell 28 can protect the storage structure 3, prevent debris from falling onto the conveyor belt 22, prevent the storage structure 3 from being blocked during movement, and improve the stability of the assembly device operation.

[0058] Furthermore:

[0059] like Figures 1 to 3 As shown;

[0060] Based on the above:

[0061] In an optional embodiment, an assembly structure 4 is provided on the top surface of the base 1 for assembling the modular displacement sensor.

[0062] The assembly structure 4 includes a mounting plate 41. Support rods 42 are fixedly connected to the four corners of the bottom surface of the mounting plate 41. The support rods 42 are fixedly connected to the top surface of the base 1. Several robotic arms 43 are installed on the top surface of the mounting plate 41.

[0063] In this embodiment, multiple robotic arms 43 can be set on the mounting plate 41 according to the assembly requirements of the modular displacement sensor, so that the modular displacement sensor can be assembled by multiple robotic arms 43 when it is being transported, thus adapting to different assembly requirements.

[0064] Furthermore:

[0065] like Figure 1 and Figure 2 As shown;

[0066] Based on the above:

[0067] To improve the assembly quality of the modular displacement sensor, in an optional embodiment, a mounting bracket 44 is fixedly connected to the top surface of the mounting plate 41 at a position away from the robotic arm 43, and a blower 45 is mounted on the mounting bracket 44.

[0068] In this embodiment: the housing of the modular displacement sensor passes under the mounting bracket 44 during the transportation process, and the blower 45 blows away the dust and impurities inside the housing of the modular displacement sensor, thereby improving the assembly quality of the modular displacement sensor.

[0069] An assembly method for a modular displacement sensor assembly device includes the following specific steps:

[0070] S1. Start the drive motor 25 through the PLC program, so that the drive motor 25 drives the transmission gear 26 to rotate. When the transmission gear 26 rotates, it will drive the conveyor belt 22 to move on the frame 21, so that the conveyor belt 22 drives the placement structure 3 on the conveyor belt 22 to perform a circular rotation. Under the control of the PLC program, the drive motor 25 is temporarily stopped when the placement structure 3 moves to the position of the robotic arm 43, so as to provide assembly time for the modular displacement sensor.

[0071] S2. Then, the staff places the housing of the modular displacement sensor to be assembled on the shelf 34 near the blower 45, so that the limiting post 36 moves within the guide port 35 and away from the center of the shelf 34. When the limiting post 36 moves, it will drive the first connecting plate 37 to move together, so that the spring 38 changes from a relaxed state to a compressed state. Under the action of the spring 38, the limiting post 36 positions and clamps the housing of the modular displacement sensor, so that the housing of the modular displacement sensor is in the center position of the shelf 34, preventing the housing of the modular displacement sensor from moving and ensuring the quality of assembly.

[0072] S3. The modular displacement sensor housing on the shelf 34 will rotate in a circle. When the modular displacement sensor housing moves to the position of the blower 45, the blower 45 will start to blow away the dust and impurities inside the modular displacement sensor housing.

[0073] S4. When the modular displacement sensor housing on the placement plate 34 moves to the position of each robotic arm 43, the modular displacement sensor will be assembled by multiple robotic arms 43 according to the assembly process of the modular displacement sensor.

[0074] S5. After assembly, the modular displacement sensor will be moved to the position where the modular displacement sensor housing is placed. The operator can use the handle 313 to rotate the collar 310, so that the collar 310 drives the guide plate 311 to move. Under the action of the guide plate 311, the first connecting plate 37 drives the limiting post 36 to move within the guide opening 35, so that the limiting post 36 no longer clamps the modular displacement sensor. This makes it convenient for the operator to take out the modular displacement sensor and place the modular displacement sensor housing to be assembled, thus realizing the assembly of the modular displacement sensor.

[0075] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
