Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electric push rods, and specifically relates to a three-way linear motion sliding module device. Background Art
[0002] Linear motion control technology has been widely applied in many fields, especially in occasions with high precision and high response speed. Traditional linear control systems mainly focus on single-axis control, such as only controlling the X-axis or Y-axis. Such a design is simple and stable, but in changing application scenarios, its function appears to be somewhat single and cannot meet the complex requirements of multi-directional and multi-degree-of-freedom motion.
[0003] With the continuous progress of technology and the increasing demand for high-precision motion control, three-way linear modules have begun to emerge. This kind of module integrates independent linear drivers in the X, Y, and Z directions, aiming to achieve precise positioning and control in three-dimensional space. With its excellent three-degree-of-freedom design, the three-way linear module has quickly gained favor in fields such as industrial automation, medical equipment, aerospace, and electronic manufacturing.
[0004] However, even though three-way linear module technology has been widely applied in many fields, the existing technology still has many limitations. Most mainstream designs adopt a series connection method, which may amplify the error of one driver and transmit it to the next driver. This may not only lead to cumulative errors in motion but also pose a threat to the stability of the overall system. In addition, many three-way modules choose a complex drive structure composed of gears and belts to achieve multi-directional motion control. Although this design achieves the purpose to a certain extent, it also brings many problems: they are often heavy, which has a negative impact on the dynamic performance of the system; their mechanical complexity increases the maintenance difficulty and raises the overall ownership cost.
[0005] Therefore, it is necessary to conduct in-depth research and improvement on the existing three-way linear module technology to overcome the above-mentioned inherent disadvantages and further improve its performance and reliability. Based on this background, the utility model patent proposes a brand-new, efficient, and precise three-way linear motion sliding module device, expecting to bring significant technological progress to related fields.

[0039] Embodiment 1:
[0040] As Figure 1 and Figure 2 shown, this embodiment provides a three - direction linear motion slide module device, which has the characteristics of simple structure and high - efficiency drive, and is suitable for various application scenarios requiring three - direction precise motion control; this embodiment is particularly suitable for the commodity pushing system in a multi - grid drawer - type vending machine.
[0041] See Figure 1, the Z-axis sliding mode assembly consists of a pair of vertically arranged Z-direction sliding rods 1 and Z-direction sliders 2 respectively arranged thereon. The Z-axis sliding mode assembly is connected to the control system and is used to receive and execute control signals; the X-axis sliding mode assembly includes an X-direction sliding rod 3 connected between two Z-direction sliders 2, and an X-direction slider 4 is arranged on the X-direction sliding rod 3. The X-axis sliding mode assembly is also connected to the control system to ensure the precise positioning and control of the X-direction slider 4; the Y-axis sliding mode assembly is arranged on the X-direction slider 4 and consists of a series of multi-section electric push rods 5. The series of multi-section electric push rods 5 are connected to the control system through its microcontroller to achieve precise control and multi-section telescopic function in the Y-axis direction.
[0042] In this embodiment, the Z-direction sliding rod 1 is designed as a long rack structure, providing high stability and precision. Specifically, the Z-direction slider 2 includes a slider housing, a driving motor is arranged inside the housing, the output end of the driving motor is connected to a driving gear, and the driving gear meshes with the long rack; in order to ensure the motion synchronization between the two Z-direction sliding rods 1, this embodiment combines a feedback system of a linear encoder. The linear encoders are respectively installed on each Z-direction sliding rod 1 to monitor the position information of the slider 2 in real time; the control system precisely adjusts the output of the driving motor according to the position information fed back by the linear encoder, so as to realize the synchronous motion of the Z-direction sliders 2 on the two Z-direction sliding rods 1, and ensure the smooth and precise motion of the X-direction sliding rod 3 connected to the two Z-direction sliders 2.
[0043] The X-axis sliding mode assembly adopts a linear slide rail mechanism to ensure that the X-direction slider 4 can move smoothly and linearly in the X direction. The X-direction slider 4 is a high-precision slider and can slide precisely along the linear slide rail to ensure the positioning accuracy in the X-axis direction; in order to drive the X-direction slider 4, this embodiment adopts a belt drive method; specifically, the belt drive system consists of a driving motor, a driving wheel, a driven wheel and a belt. The driving wheel and the driven wheel are respectively installed at both ends of the X-direction sliding rod 3, and the belt bypasses the driving wheel and the driven wheel to form a closed transmission loop; the driving motor is connected to the driving wheel through a coupling. When the driving motor rotates forward and backward, the driving wheel drives the belt to move back and forth in a cycle along the inside of the X-direction sliding rod 3; since the X-direction slider 4 is fixedly connected above the belt, the forward and backward movement of the belt will directly drive the X-direction slider 4 to linearly move in the slider long groove above the X-direction sliding rod 3.
[0044] The belt drive system realizes the efficient linear motion of the X-axis sliding mode assembly, and at the same time greatly simplifies the structure of the driving mechanism and avoids complex mechanical transmission devices; in addition, the belt drive method has low friction and wear characteristics, which not only reduces the overall volume of the sliding mode assembly, but also extends the service life of the equipment and reduces the maintenance requirements.
[0045] To ensure the precise control and feedback of the device's movement, in this embodiment, linear encoders are respectively provided on the Z-axis slide bar 1 and the X-axis slide bar 3. These encoders can detect the position of the slider in the Z-axis and X-axis directions in real time and feed the data back to the control system.
[0046] As Figure 4 and Figure 5 shown, the series multi-section electric push rod 5 is a two-stage electric push rod, and its structure includes a first electric push rod 501 and a second electric push rod 502, which are connected by a series baffle 506; the series baffle 506 is a rectangular flat plate structure made of high-strength metal, including a fixed connection part 507 at the lower part and a rod-passing part 508 at the upper part, and a pipe-passing hole 509 is provided on the rod-passing part 508.
[0047] In Figure 4 it, the shaded part shows the connection relationship between the components; the fixed connection part 507 is horizontally connected to the first electric push rod 501, and the inner pipe 504 is fixedly connected to the fixed connection part 507, and the connection method can be threaded connection or welding; the rod-passing part 508 is horizontally connected to the second electric push rod 502, and the outer pipe 503 is fixedly connected to the rod-passing part 508, and the connection method can also be threaded connection or welding; the inner pipe 504 of the second electric push rod 502 can pass through the pipe-passing hole 509 of the rod-passing part 508.
[0048] Both the first electric push rod 501 and the second electric push rod 502 are linear electric push rods, including an outer pipe 503, an inner pipe 504 and a push rod housing 505. A driving device and a control device are arranged inside the push rod housing; in this embodiment, both the outer pipe 503 and the inner pipe 504 are hollow cylindrical structures, and the inner pipe 504 can axially expand and contract along the outer pipe 503 under the drive of the driving device.
[0049] This structure connects two electric push rods through the series baffle 506, realizing the multi-section telescopic function in the Y-axis direction; as Figure 5 shown, the outer pipe 503 of the first electric push rod 501 is pushed out to the right, and the inner pipe 504 of the second electric push rod 502 passes through the pipe-passing hole 509 and is pushed out to the left, increasing the stroke range and flexibility of the push rod.
[0050] In addition, to improve the safety of the system, in this embodiment, stroke limit devices 6 are both provided on the Z-axis slide bar 1 and the X-axis slide bar 3; the stroke limit device 6 is an inductive limiter, which can detect the position of the slider when it approaches the stroke limit position and send a signal to the control system; the control system slows down or stops the movement of the slider in a timely manner according to this signal, thus avoiding mechanical shock and equipment damage caused by sudden stop or over-limit movement.
[0051] Next, the working process of the three-way linear motion slide module device in this embodiment will be described:
[0052] I. Z-axis motion control: When motion in the Z-axis direction is required, the control system activates the drive motor within the Z-axis slider 2 according to the preset instructions. The drive motor drives the drive gear to mesh with the long rack of the Z-axis slide bar 1, pushing the Z-axis slider 2 to move vertically along the Z-axis slide bar 1.
[0053] To ensure the synchronous movement of the sliders 2 on the two Z-axis slide bars 1, the linear encoder monitors the position of the sliders in real time. The control system precisely adjusts the output of the drive motor based on the data feedback from the encoder, ensuring the synchronous movement of the sliders on the two slide bars, thereby ensuring the balance and stability of the X-axis slide bar 3.
[0054] II. X-axis motion control: After the Z-axis positioning is completed, if movement in the X-axis direction is required, the control system activates the drive motor in the X-axis sliding mode component; the drive motor drives the drive wheel inside the X-axis slide bar 3 through a coupling, and the drive wheel drives the belt, which in turn drives the X-axis slider 4 to move in the X-axis direction.
[0055] III. Y-axis motion control: After the X-axis positioning is completed, if precise pushing and pulling operations in the Y-axis direction are required, the control system activates the series multi-section electric push rod 5 through a microcontroller, and controls the series multi-section electric push rod 5 to achieve multi-section expansion and contraction.
[0056] During the movement of each axis, the stroke limit device 6 monitors the position of the slider in real time through an inductive limiter; when the slider approaches the set stroke limit position, the inductive limiter will detect this situation and send a signal to the control system; the control system slows down or stops the movement of the slider in a timely manner according to this signal, preventing mechanical shock and equipment damage caused by sudden stop or over-limit movement, and ensuring the safe operation of the system.
[0057] During the entire operation process, the linear encoder and the inductive limiter continuously feedback real-time position information to the control system. The control system adjusts the operations of each drive component based on this data, ensuring the synchronism, smoothness, and accuracy of each moving axis. At the same time, the system will detect and handle abnormal situations, such as issuing warnings and stopping operations when necessary.
[0058] Embodiment 2:
[0059] To further increase the expansion and contraction stroke of the Y-axis sliding mode component, in this embodiment, the series multi-section electric push rod is a four-stage electric push rod, see Figure 6, the four-stage electric push rod is sequentially denoted as the first electric push rod A, the second electric push rod B, the third electric push rod C, and the fourth electric push rod D from bottom to top. The first electric push rod A is fixedly arranged on the base 705; each stage of the electric push rod is composed of a driving part and a push rod part. The driving part includes a motor and a transmission mechanism, which are encapsulated in a rectangular housing. The motor drives the telescopic rod of the push rod part to perform telescopic movement through the transmission mechanism; the push rod part includes a push rod tube 701 and a telescopic rod 702 arranged in the push rod tube. One end of the telescopic rod 702 is connected to the transmission mechanism, and the other end is fixedly connected to the push rod tube 701 of the next-stage electric push rod through a series baffle 703 to achieve multi-stage telescoping of the multi-stage push rod.
[0060] In order to ensure the synchronous movement and structural stability between the upper and lower adjacent electric push rods, a slide rail mechanism is arranged between the upper and lower adjacent electric push rods. The slide rail mechanism includes a slide bar 704 arranged on the lower wall of the push rod tube 701 of the upper electric push rod, and a chute (not shown in the figure) arranged on the push rod tube of the lower electric push rod. The slide bar is slidably matched with the chute to guide and limit the relative movement of the upper and lower adjacent electric push rods to ensure the stability and coaxiality of the push rod during the telescopic process.
[0061] Other technical features of this embodiment are the same as those of Embodiment 1.
[0062] In summary, the three-way linear motion sliding module device of this embodiment realizes efficient, stable, and safe three-dimensional motion control through precise control and feedback mechanisms, and is particularly suitable for application scenarios such as multi-grid drawer-type vending machines that require precise positioning and flexible operation.
