Description

Technical Field

[0001] The present invention belongs to the technical field of displacement sensors, and in particular relates to an assembling device and method of a modular displacement sensor. Background Art

[0002] A modular displacement sensor is a displacement sensor with flexible configuration and scalability, and is generally used to measure physical quantities such as object position, distance, and displacement. Unlike traditional single-design displacement sensors, modular displacement sensors are composed of multiple functional modules, each of which can be used independently or combined as needed, thereby providing more customization options and flexibility. In the prior art, linear automated assembly equipment is generally used to assemble modular displacement sensors. A linear conveyor platform transports the modular displacement sensor housing to be assembled, and a robotic arm assembles the modular displacement sensor while the housing is moving.

[0008] As a preferred assembly device for a modular displacement sensor of the present invention, the storage plate is provided with four guide openings arranged in a ring, each of the guide openings is slidably connected to a limiting column, and the top ends of the limiting columns are all slope structures.

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

[0017] S1. The drive motor is started through the PLC program, causing the drive motor to drive the transmission gear to rotate. When the transmission gear rotates, it drives the conveyor belt to move on the frame, thereby causing the conveyor belt to drive the storage structure on the conveyor belt to perform circular rotation. Under the control of the PLC program, the drive motor is temporarily stopped when the storage structure moves to the position of the robotic arm to provide time for the modular displacement sensor to be assembled;

[0018] S2. The staff then places the modular displacement sensor housing to be assembled on a storage plate near the hair dryer. The limiting post moves within the guide opening and away from the center of the storage plate. The movement of the limiting post drives the first connecting plate to move together, causing the spring to change from a relaxed state to a compressed state. The limiting post, under the action of the spring, positions and clamps the modular displacement sensor housing, centered on the storage plate. This prevents movement and ensures assembly quality.

[0019] S3. The modular displacement sensor housing on the storage plate will perform a circular rotation. When the modular displacement sensor housing moves to the position of the blower, the blower will start to blow away the dust and impurities in the modular displacement sensor housing.

[0020] S4. When the modular displacement sensor housing on the storage plate moves to the position of each robotic arm, the modular displacement sensor is assembled by multiple robotic arms according to the modular displacement sensor assembly process;

[0021] S5. After assembly, the modular displacement sensor will be moved to the position where the modular displacement sensor housing is placed. The staff can use the handle to drive the ring to rotate, so that the ring drives the guide plate to move, and the first connecting plate drives the limit column to move in the guide port under the action of the guide plate, so that the limit column no longer clamps the modular displacement sensor, making it convenient for the staff to take out the modular displacement sensor and place the modular displacement sensor housing to be assembled, thereby realizing the assembly of the modular displacement sensor.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: a conveying structure is added to the present application, and the transmission teeth and the tooth block group can be used in conjunction with each other. The drive motor is started by the PLC program, so that the drive motor drives the transmission teeth to rotate. When the transmission teeth rotate, the conveyor belt is driven to move on the frame, so that the conveyor belt drives the storage structure on the conveyor belt to perform a circular rotation motion. Under the control of the PLC program, the drive motor is temporarily stopped when the storage structure moves to the position of the robot arm, providing assembly time for the modular displacement sensor. The assembly of multiple modules can be achieved without a long linear conveying platform, which occupies a small space and is convenient to use. At the same time, the storage structure is added, and the staff The housing of the modular displacement sensor to be assembled can be placed on the placement plate, so that the limit column moves in the guide port and away from the center of the placement plate, and when the limit column moves, it will drive the first connecting plate to move together, so that the spring changes from a relaxed state to a compressed state, so that the limit column positions and clamps the housing of the modular displacement sensor under the action of the spring, so that the housing of the modular displacement sensor is located in the center of the placement plate, preventing the housing of the modular displacement sensor from moving randomly on the placement plate, ensuring the quality of assembly, and when used in conjunction with the conveying structure, the housing of the modular displacement sensor can be accurately moved to the assembly position of each assembly arm, making it convenient to assemble the modular displacement sensor.

[0040] In order 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, and a tooth block group 23 is fixedly connected to the inner wall at the bottom of the conveyor belt 22. The base 1 is provided with a mounting groove 24 near any inner corner of the conveyor belt 22. A drive motor 25 is installed in the mounting groove 24. A transmission tooth 26 is fixedly connected to the output shaft of the drive motor 25. The transmission tooth 26 is meshed with the tooth block group 23. The conveyor belt 22 is connected to the transmission tooth 26 through the tooth block group 23. Several storage structures 3 are equidistantly arranged on the top surface of the conveyor belt 22.

[0042] In this embodiment, a servo motor is used as the drive motor 25, which is started by a PLC program, so that the drive motor 25 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 storage structure 3 on the conveyor belt 22 to perform a circular rotational motion. Under the control of the PLC program, the drive motor 25 is temporarily stopped when the storage structure 3 moves to the position of the robotic arm 43, providing assembly time for the modular displacement sensor. Multiple modules can be assembled without a long linear conveying platform, occupying a small space and being convenient to use.

[0043] Going further:

[0044] like Figures 6 to 8 As shown;

[0045] Combining the above:

[0046] In order to position and transport the modular displacement sensor to be assembled, in an optional embodiment, the storage structure 3 includes a first connecting column 31, which is fixedly connected to the top surface of the frame 21, and the top of the first connecting column 31 is fixedly connected to the fixing plate 32, and the center position of the top surface of the fixing plate 32 is fixedly connected to the second connecting column 33, and the top of the second connecting column 33 is fixedly connected to the storage plate 34. Four guide openings 35 arranged in a ring are opened on the storage plate 34, and each guide opening 35 is slidably connected to a limiting column 36. The top of the limiting column 36 is a slope structure, and the bottom end of each limiting column 36 is fixedly connected to the first connecting plate 37. Each first connecting plate 37 is fixedly connected to a spring 38 on the side away from the second connecting column 33, and each spring 38 is fixedly connected to a second connecting plate 39 on the end away from the first connecting plate 37. The top of each second connecting plate 39 is fixedly connected to the bottom surface of the storage plate 34, and the bottom end of each second connecting plate 39 is fixedly connected to the outer wall of the fixing plate 32.

[0047] In this embodiment: when in use, the staff places the housing of the modular displacement sensor to be assembled on the storage plate 34, so that the limit column 36 moves in the guide opening 35 and away from the center of the storage plate 34. At the same time, since the top of the limit column 36 is a slope structure, it is convenient for the staff to place the modular displacement sensor housing, and when the limit column 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, so that the limit column 36 positions and clamps the housing of the modular displacement sensor under the action of the spring 38, so that the housing of the modular displacement sensor is in the center position of the storage plate 34, preventing the housing of the modular displacement sensor from moving, and ensuring the quality of assembly.

[0048] Going further:

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

[0050] Combining the above:

[0051] In order to facilitate the staff to take and place the modular displacement sensor, in an optional embodiment, a ring 310 is rotatably connected to the outer wall of the second connecting column 33, and the position of the ring 310 near the first connecting plate 37 is fixedly connected to a guide plate 311. The end of each guide plate 311 close to the ring 310 is arranged between the ring 310 and the adjacent first connecting plate 37. A connecting rod 312 is fixedly connected to the bottom surface of the ring 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 staff can use the handle 313 to rotate the ring 310, so that the ring 310 drives the guide plate 311 to move, and the first connecting plate 37 drives the limit column 36 to move in the guide opening 35 under the action of the guide plate 311, so that the limit column 36 no longer clamps the modular displacement sensor, making it convenient for the staff to take out the modular displacement sensor and place the modular displacement sensor housing to be assembled.

[0053] Going further:

[0054] like Figures 3 to 5 As shown;

[0055] Combining the above:

[0056] In order 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.

[0058] Going further:

[0059] like Figures 1 to 3 As shown;

[0060] Combining the above:

[0061] In order to assemble the modular displacement sensor, in an optional embodiment, an assembly structure 4 is provided on the top surface of the base 1;

[0062] The assembly structure 4 includes a mounting plate 41 , and 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, a plurality of robotic arms 43 may be provided 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 the plurality of robotic arms 43 when being transported, thereby adapting to different assembly requirements.

[0064] Going further:

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

[0066] Combining the above:

[0067] In order 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 away from the mechanical arm 43 , and a blower 45 is installed on the mounting bracket 44 .

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

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

[0070] S1. The drive motor 25 is started by the PLC program, causing the drive motor 25 to rotate the transmission gear 26. 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 storage 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 storage structure 3 moves to the position of the robot arm 43 to provide time for the modular displacement sensor to be assembled.

[0071] S2. The staff then places the modular displacement sensor housing to be assembled on the storage plate 34 near the hair dryer 45. The limiting post 36 moves within the guide opening 35 and away from the center of the storage plate 34. The movement of the limiting post 36 drives the first connecting plate 37 to move together, 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 modular displacement sensor housing, keeping the modular displacement sensor housing at the center of the storage plate 34, preventing the modular displacement sensor housing from moving and ensuring assembly quality.

[0072] S3: The modular displacement sensor housing on the storage plate 34 performs a circular rotation. When the modular displacement sensor housing moves to the position of the blower 45, the blower 45 starts to blow away dust and impurities in the modular displacement sensor housing.

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

[0074] S5. After assembly, the modular displacement sensor will be moved to the position where the modular displacement sensor housing is placed. The staff can use the handle 313 to rotate the ring 310, so that the ring 310 drives the guide plate 311 to move, and the first connecting plate 37 drives the limit column 36 to move in the guide opening 35 under the action of the guide plate 311, so that the limit column 36 no longer clamps the modular displacement sensor, making it convenient for the staff to take out the modular displacement sensor and place the modular displacement sensor housing to be assembled, thereby completing 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 aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
