Description

Technical Field

[0001] This utility model relates to the field of mobile positioning technology, and in particular to a dual positioning device for a vehicle. Background Technology

[0002] The trolley travel device is a common motion control component in industrial automation and mechanical transmission systems. It is widely used in automated production lines, warehousing and logistics, robots, machine tools and other fields. In modern industrial automation and mechanical transmission systems, the positioning accuracy of the trolley travel device is a key factor affecting the operating efficiency and reliability of the entire system.

[0003] Traditional vehicle positioning devices are prone to problems due to the susceptibility of ambient light interference caused by the use of a single photoelectric sensor. Furthermore, they may experience detection delays or misjudgments under high-speed movement or complex working conditions, leading to decreased positioning accuracy and potential deviations in station positions. Therefore, those skilled in the art have developed a dual positioning device for vehicle movement to address the issues mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dual positioning device for vehicle movement. By using a first positioning device and a second positioning device in conjunction, it ensures that the station position will not deviate, thus achieving dual positioning and improving the accuracy of positioning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual positioning device for a trolley, comprising two support rods and multiple connecting rods. The two support rods are arranged in a front-to-back configuration, and the multiple connecting rods are arranged in a transverse configuration at the center between the two support rods. Each of the upper surfaces of the two support rods is provided with a guide rail, and each of the upper surfaces of the two guide rails is provided with three sliders arranged in a transverse configuration at the center. The trolley body is located at the center of the upper surface of the six sliders. A rack is provided at the center of the upper surface of the support rod at the rear end. A first positioning device is provided at the rear end of one side of the central support frame at the lower end of the trolley body, and a second positioning device is provided at the rear end of the center of one side of the central support frame at the lower end of the trolley body.

[0006] The first positioning device includes a first mounting plate, which is disposed on one side of the lower support frame of the trolley body. A connecting plate is provided at the center of one side of the first mounting plate. A bearing seat is provided at the center of the rear end face of the connecting plate. A mounting block is provided at the center of the upper end face of the bearing seat. A drive motor is provided at the center of the upper end face of the mounting block. An encoder is provided inside the mounting block at the center of the upper end face of the bearing seat. A connecting shaft is provided at the center of the lower end face of the bearing seat. A gear is provided at the end of the connecting shaft.

[0007] The above technical solution involves starting the drive motor, transmitting the rotational motion to the rack via the connecting shaft and gears, driving the main body of the trolley to move on the guide rail, and then sliding the slider on the guide rail to ensure the smooth movement of the main body of the trolley. The encoder monitors the rotation angle and position of the drive motor in real time and feeds the information back to the control system. The control system then precisely controls the movement of the drive motor based on the feedback information from the encoder, thereby achieving precise control of the position of the main body of the trolley.

[0008] Furthermore, the gear and the rack mesh with each other;

[0009] With the above technical solution, when the drive motor starts, the gear begins to rotate, and through meshing with the rack, the rotational motion is converted into linear motion.

[0010] Furthermore, the drive motor rotating shaft and the encoder rotating shaft are fixedly connected;

[0011] The above technical solution involves directly connecting the encoder's rotating shaft to the drive motor's rotating shaft. The encoder indirectly measures the drive motor's rotation state by detecting the rotation angle and speed of its own rotating shaft.

[0012] Furthermore, the second positioning device includes a second mounting plate, which is located at the rear center of a fixed bracket on one side of the lower end of the trolley body. Four mounting holes are arranged in a rectangular pattern at the upper center of one side of the second mounting plate, and a fixed plate is located at the lower center of one side of the second mounting plate. Four mounting sliding holes are arranged in a rectangular pattern at the center of the upper surface of the fixed plate. Photoelectric sensors are provided at the rear center of the mounting sliding holes on one side and at the front and rear center of the mounting sliding holes on the other side.

[0013] The above technical solution uses a second mounting plate to fix and support the fixed plate, and then uses mounting holes to support and install the photoelectric sensor. The photoelectric sensor emits and receives light signals to detect the target position. When the main body of the car moves to the predetermined position, the photoelectric sensor detects the target object and sends a signal. The control system adjusts the movement of the drive motor in real time according to the feedback signal from the photoelectric sensor, thereby achieving precise control of the position of the main body of the car.

[0014] Furthermore, a fixed rail is provided at the rear center of the upper end face of the multiple connecting rods, and a positioning block is provided at one side of the front end face and one end of the rear end face of the fixed rail.

[0015] Through the above technical solution, by fixing and adjusting the position of the positioning block with a fixed rail, when the trolley moves to the corresponding position, the photoelectric sensor first detects the positioning block, and then checks the position information with the current position of the encoder to ensure that the station position is not deviated, thus achieving dual positioning and improving the accuracy of positioning.

[0016] Furthermore, the output ends of the three photoelectric sensors respectively pass through two mounting sliding holes to the lower end of the fixing plate;

[0017] The above technical solution uses a photoelectric sensor to transmit signals to the lower end of the fixed plate, and works with the positioning block to achieve positioning.

[0018] Furthermore, a drag chain frame is provided at the rear center of the upper end face of multiple connecting rods, and a drag chain body is fixedly connected at the rear center of the upper end face of the fixing frame on one side of the lower end of the trolley body, and the drag chain body and the drag chain frame are sleeved together.

[0019] The above technical solution uses the internal structure of the cable chain to accommodate and protect various cables, preventing them from being worn or interfered with during movement. The cable chain moves synchronously with the trolley body, and the cable chain frame provides guidance and support for the cable chain, ensuring that the cable chain will not become tangled or jammed during movement.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the dual positioning device for trolley movement is used, when the trolley body moves to the predetermined position, the photoelectric sensor detects the positioning block, then checks the position information with the current position of the encoder, and then the encoder monitors the rotation angle and position of the drive motor in real time and feeds the information back to the control system. Then, the control system precisely controls the movement of the drive motor according to the feedback information from the encoder, thereby achieving precise control of the position of the trolley body and ensuring that the station position will not deviate, thus achieving dual positioning and improving the accuracy of positioning.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-5 This utility model provides an embodiment of a dual positioning device for a trolley, comprising two support rods 1 and multiple connecting rods 2. The two support rods 1 are arranged front to back, and the multiple connecting rods 2 are arranged laterally at the center between the two support rods 1. Each support rod 1 has a guide rail 3 at the center of its upper end face, and each guide rail 3 has three sliders 4 arranged laterally at the center of its upper end face. The trolley body 5 is located at the center of the upper end face of the six sliders 4. A rack 6 is located at the front end of the upper end face of the rear support rod 1. A first positioning device 7 is located at the rear end of one side of the central support frame at the lower end of the trolley body 5, and a second positioning device 8 is located at the rear end of one side of the central support frame at the lower end of the trolley body 5. The first positioning device 7 and the second positioning device 8 work together to ensure that the station position is not deviated, thus achieving dual positioning and improving the accuracy of positioning.

[0031] like Figure 2 , 3As shown, the first positioning device 7 includes a first mounting plate 701, which is disposed on one side of the lower support frame of the trolley body 5. A connecting plate 702 is provided at the center of one side of the first mounting plate 701. A bearing seat 703 is provided at the center of the rear end face of the connecting plate 702. A mounting block 704 is provided at the center of the upper end face of the bearing seat 703. A drive motor 705 is provided at the center of the upper end face of the mounting block 704. An encoder 706 is provided inside the mounting block 704 at the center of the upper end face of the bearing seat 703. A connecting shaft 707 is provided at the center of the lower end face of the bearing seat 703. A gear 708 is provided at the end of 707. It is started by a drive motor 705. The rotational motion is transmitted to the rack 6 through the connecting shaft 707 and the gear 708, driving the trolley body 5 to move on the guide rail 3. Then, the slider 4 slides on the guide rail 3 to ensure the smooth movement of the trolley body 5. The encoder 706 monitors the rotation angle and position of the drive motor 705 in real time and feeds the information back to the control system. The control system then precisely controls the movement of the drive motor 705 based on the feedback information from the encoder 706, thereby achieving precise control of the position of the trolley body 5.

[0032] Gear 708 meshes with rack 6. When drive motor 705 starts, gear 708 begins to rotate and converts rotational motion into linear motion through meshing with rack 6.

[0033] The rotating shaft of the drive motor 705 is fixedly connected to the rotating shaft of the encoder 706. The rotating shaft of the encoder 706 is directly connected to the rotating shaft of the drive motor 705. The encoder 706 indirectly measures the rotation state of the drive motor 705 by detecting the rotation angle and speed of its own rotating shaft.

[0034] like Figure 4 , 5 As shown, the second positioning device 8 includes a second mounting plate 801, which is located at the rear center of one side of the fixed frame at the lower end of the trolley body 5. Four mounting holes 802 are arranged in a rectangular pattern at the upper center of one side of the second mounting plate 801. A fixed plate 803 is located at the lower center of one side of the second mounting plate 801. Four mounting sliding holes 804 are arranged in a rectangular pattern at the center of the upper surface of the fixed plate 803. Photoelectric sensors 805 are located at the rear center of one mounting sliding hole 804 and the front center of the other mounting sliding hole 804. The fixed plate 803 is fixed and supported by the second mounting plate 801, and the photoelectric sensors 805 are supported and installed by the mounting sliding holes 804. The photoelectric sensors 805 emit and receive light signals to detect the target position. When the trolley body 5 moves to the predetermined position, the photoelectric sensor 805 detects the target object and sends a signal. The control system adjusts the movement of the drive motor 705 in real time based on the feedback signal from the photoelectric sensor 805, thereby achieving precise control of the position of the trolley body 5.

[0035] A fixed rail 806 is provided at the rear center of the upper end face of multiple connecting rods 2. A positioning block 807 is provided at one side of the center of the front end face and one end of the center of the rear end face of the fixed rail 806. The positioning block 807 is fixed and its position is adjusted by the fixed rail 806. When the trolley moves to the corresponding position, the photoelectric sensor 805 first detects the positioning block 807, and then checks the position information with the current position of the encoder 706 to ensure that the station position is not deviated, thus achieving dual positioning and improving the accuracy of positioning.

[0036] The output ends of the three photoelectric sensors 805 pass through the two mounting sliding holes 804 and lead to the lower end of the fixed plate 803. Through the passage of the photoelectric sensors 805, they can transmit signals to the lower end of the fixed plate 803 and cooperate with the positioning block 807 to achieve positioning.

[0037] Multiple connecting rods 2 are provided with a drag chain frame 9 at the rear center of the upper end face. A drag chain body 10 is fixedly connected to the rear center of the upper end face of the fixed frame on one side of the lower end of the trolley body 5. The drag chain body 10 and the drag chain frame 9 are sleeved and connected. The drag chain body 10 is used to accommodate and protect various cables to prevent the cables from being worn or interfered with during movement. The drag chain body 10 moves synchronously with the movement of the trolley body 5. The drag chain frame 9 provides guidance and support for the drag chain body 10 to ensure that the drag chain body 10 will not get tangled or stuck during movement.

[0038] Working principle: When the dual positioning device for trolley movement is used, the device also includes a control system. In the trolley movement device, the control system is the core part to achieve precise motion control and positioning. It receives signals from various sensors, analyzes and processes them, and sends corresponding control commands to the actuator. This solution is a commonly used technical means in the existing technology, which will not be elaborated on here, in order to achieve precise control of the trolley body 5.

[0039] The drive motor 705 is started, and the rotational motion is transmitted to the rack 6 through the connecting shaft 707 and the gear 708, driving the trolley body 5 to move on the guide rail 3. The slider 4 then slides on the guide rail 3 to ensure the smooth movement of the trolley body 5. The encoder 706 monitors the rotation angle and position of the drive motor 705 in real time and feeds the information back to the control system. The control system then precisely controls the movement of the drive motor 705 based on the feedback information from the encoder 706, thereby achieving precise control of the position of the trolley body 5.

[0040] The second mounting plate 801 provides fixed support for the fixed plate 803, and the mounting sliding hole 804 supports and installs the photoelectric sensor 805. The photoelectric sensor 805 emits and receives light signals to detect the target position. When the trolley body 5 moves to the predetermined position, the photoelectric sensor 805 detects the target object and sends a signal. The control system adjusts the movement of the drive motor 705 in real time based on the feedback signal from the photoelectric sensor 805, thereby achieving precise control of the position of the trolley body 5. The fixed rail 806 fixes and adjusts the position of the positioning block 807. When the trolley moves to the corresponding position, the photoelectric sensor 805 first detects the positioning block 807, and then checks the position information with the current position of the encoder 706 to ensure that the station position is not deviated, thus achieving dual positioning and improving the accuracy of positioning.

[0041] The cable carrier body 10 is used to house and protect various cables, preventing them from being worn or interfered with during movement. The cable carrier body 10 moves synchronously with the trolley body 5. The cable carrier frame 9 provides guidance and support for the cable carrier body 10, ensuring that the cable carrier body 10 will not become tangled or stuck during movement.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
