Description

Technical Field

[0001] This utility model relates to the field of automation equipment, and in particular to a linear module with integrated rolling auxiliary support. Background Technology

[0002] Linear modules, as key transmission components in automation, are increasingly widely used in scenarios requiring long-stroke motion, such as product assembly and logistics sorting. In these long-stroke modules, the cover plate, as an important component protecting the internal structure, is usually positioned between the front and rear plates. Its own weight and material fatigue over long-term use can easily lead to downward deformation and collapse in the middle area. In existing technologies, the cover plate is fixed only by connections at both ends to the end plates, lacking an intermediate support structure. When the module stroke is long, the cover plate collapse problem becomes more prominent: on the one hand, the collapsed cover plate may cause frictional interference with the sliding seat below, hindering the normal movement of the sliding seat and accelerating component wear.

[0003] Therefore, it is necessary to design a linear module with integrated rolling auxiliary support to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a linear module with integrated rolling auxiliary support for dynamic prevention of cover plate collapse.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a linear module with integrated rolling auxiliary support, comprising:

[0006] The module body includes a base, a front plate located at the front end of the base, a rear plate located at the rear end of the base, a guide rail and a cover plate located on the base, wherein the cover plate is located on the front plate and the rear plate.

[0007] The drive assembly includes a motor, a transmission mechanism poweredly connected to the motor, and a conveyor belt connected to the transmission mechanism;

[0008] A sliding seat is fixed on the conveyor belt. The bottom of the sliding seat is provided with a slider that cooperates with the guide rail. The conveyor belt drives the sliding seat to move along the guide rail.

[0009] The first wheel assembly is disposed between the sliding seat and the cover plate. The first wheel assembly includes a first bracket and a plurality of first wheels disposed on the first bracket. The outer peripheral surface of the first wheel is tangent to the lower surface of the cover plate. When the sliding seat moves, the first wheel assembly moves with the sliding seat.

[0010] As a further improvement of the present invention, the transmission mechanism includes a driving wheel, a first driven wheel, a transmission belt connecting the driving wheel and the first driven wheel, a second driven wheel and a third driven wheel coaxially connected to the first driven wheel, and the transmission belt is located between the second driven wheel and the third driven wheel.

[0011] As a further improvement of the present invention, the sliding seat includes a body, a locking block and a bolt for fixing the locking block to the body, the conveyor belt is fixed between the locking block and the body, and the locking block has several transverse slots on the side facing the conveyor belt.

[0012] As a further improvement of the present invention, the body includes a horizontal part and vertical parts disposed on both sides of the horizontal part, wherein the upper surface of the vertical part is higher than the upper surface of the cover plate.

[0013] As a further improvement of the present invention, the number of the first wheels is multiple, and they are divided into two groups symmetrically arranged on the upper surface of the horizontal part.

[0014] As a further improvement of the present invention, it also includes several second wheel sets. The second wheel set includes a second bracket fixed on the base and a second wheel disposed on the second bracket. The second driven wheel and the third driven wheel divide the conveyor belt into an upper section and a lower section. The outer peripheral surface of the second wheel is tangent to the lower surface of the conveyor belt located in the lower section.

[0015] As a further improvement of the present invention, a plurality of second wheel sets are evenly distributed along the length direction of the conveyor belt.

[0016] As a further improvement of this utility model, the length of the second wheel is greater than the width of the conveyor belt.

[0017] As a further improvement of this utility model, the first wheel is a rubber-coated wheel, and the second wheel is a rubber-coated wheel.

[0018] As can be seen from the above technical solution, the linear module with integrated rolling auxiliary support of this utility model solves the problem of cover plate collapse in long-stroke linear modules by setting a first wheel group between the sliding seat and the cover plate. Specifically, it has the following advantages: First, the first wheel group moves synchronously with the sliding seat, and its first wheel always maintains tangential contact with the lower surface of the cover plate, forming dynamic support for the cover plate. When the cover plate tends to collapse downwards due to gravity or fatigue, the first wheel group can provide upward support force in real time, especially in the middle region of the long-stroke module, which can significantly suppress the deformation of the cover plate and ensure that the cover plate always remains flat. Second, a stable gap is maintained between the flat cover plate and the sliding seat, completely eliminating the friction risk caused by cover plate collapse and ensuring smooth movement of the sliding seat along the guide rail. Furthermore, the dynamic support of the first wheel assembly for the cover plate reduces cover plate vibration and avoids resonance caused by cover plate deformation, ensuring a stable trajectory for the sliding seat during high-speed, long-distance movement. Combined with the guiding structure of the bottom slider and guide rail, the positioning accuracy deviation of the entire module can be controlled within a smaller range throughout its entire stroke, meeting the stringent requirements of precision machining for long-stroke movements. Finally, the first wheel assembly is directly integrated into the sliding seat, eliminating the need for additional fixed support structures. This achieves effective protection of the long-stroke cover plate without altering the overall module dimensions, balancing lightweight design and cost control. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please refer to Figures 1 to 3As shown, this utility model provides a linear module with integrated rolling auxiliary support, which includes a module body 10, a drive assembly 20, a sliding seat 30, a first wheel set 40, and a second wheel set (not shown). The module body 10 includes a base 11, a front plate 13 disposed at the front end of the base 11, a rear plate disposed at the rear end of the base, a guide rail 12 disposed on the base 11, and a cover plate 15, with the cover plate 15 disposed on the front plate 13 and the rear plate.

[0028] Please refer to Figure 2 and Figure 6 As shown, the drive assembly 20 includes a motor 21, a transmission mechanism powered by the motor 21, and a conveyor belt 28 connected to the transmission mechanism. The transmission mechanism includes a drive wheel 22, a first driven wheel 23, a transmission belt 24 connecting the drive wheel 22 and the first driven wheel 23, a second driven wheel 25, and a third driven wheel (not shown) coaxially connected to the first driven wheel 23, all mounted side-by-side on the front end plate 13. The motor 21 is mounted on the mounting plate 26, with the motor 21 and the drive wheel 22 located on opposite sides of the mounting plate 26. The mounting base 27 is a hollow rectangle. The second driven wheel 25 is mounted on the mounting base 27 and coaxially mounted to the first driven wheel 23 via a connecting shaft. The third driven wheel is rotatably mounted at the far end of the base 11. The conveyor belt 28 is located between the second driven wheel 25 and the third driven wheel 29. The second driven wheel 25 and the third driven wheel 29 divide the conveyor belt 28 into an upper section and a lower section.

[0029] Please refer to Figures 3 to 5 As shown, the sliding seat 30 is fixed to the upper section of the conveyor belt 28. The bottom of the sliding seat 30 has a slider 32 that cooperates with the guide rail 12. The conveyor belt 28 drives the sliding seat 31 to move along the guide rail 12. Specifically, the sliding seat 30 includes a body 31, a locking block 33, and bolts that fix the locking block 33 to the body 31. The conveyor belt 28 is fixed between the locking block 33 and the body 31. The locking block 33 has several transverse slots on the side facing the conveyor belt 28 to increase the coefficient of friction between the locking block 33 and the conveyor belt 28, effectively preventing slippage of the conveyor belt 28 during movement. The body 31 includes a horizontal portion 311 and vertical portions 312 on both sides of the horizontal portion 311. The upper surface of the vertical portion 312 is higher than the upper surface of the cover plate 28. A platform or carrier adapted to the product can be installed above the vertical portion 312 according to actual transportation needs; details are omitted here.

[0030] Please refer to Figure 2 , Figure 3 and Figure 4As shown, the first wheel assembly 40 is disposed between the sliding seat 30 and the cover plate 15. When the sliding seat 30 moves, the first wheel assembly 40 moves with the sliding seat 30. The first wheel assembly 40 includes a mounting base 43, a first bracket 41 disposed on the mounting base 43, and a plurality of first wheels 42 disposed on the first bracket 41. The outer peripheral surface of the first wheel 42 is tangent to the lower surface of the cover plate 15 (see reference). Figure 3 (As shown). There are multiple first wheels 42, divided into two groups, symmetrically arranged on the upper surface of the horizontal part 311 with the center line of the cover plate length direction as the axis of symmetry. The first wheels 42 are preferably rubber-coated wheels, and the rubber material can be polyurethane, which is wear-resistant and will not damage the cover plate 15 during rolling.

[0031] Please refer to Figure 6 and Figure 7 As shown, the second wheel set 50 is located below the conveyor belt 28, and several second wheel sets 50 are evenly distributed along the length of the conveyor belt 28. Each second wheel set 50 includes a second bracket 51 fixed to the base 11 and a second wheel 52 mounted on the second bracket 51. The outer circumferential surface of the second wheel 52 is tangent to the lower surface of the lower section of the conveyor belt 28. The even distribution of the second wheel sets 50 along the length of the conveyor belt 28 distributes the weight of the conveyor belt 28 to multiple support points, preventing sagging in the middle section due to the excessive length of the conveyor belt 28 (especially for the lower section, which is more prone to sagging due to its own weight when there is no material weight above), ensuring that the conveyor belt 28 is always taut. The length of the second wheel 52 is greater than the width of the conveyor belt 28. Even if the edge of the conveyor belt 28 deviates slightly, it can still be supported by the excess portion of the second wheel 52, preventing the conveyor belt 28 from deviating further due to localized suspension. The second wheel 52 is a rubber-coated wheel; the rubber material can be polyurethane, which is wear-resistant and will not damage the conveyor belt 28 during rolling.
