Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electromechanical devices, in particular to a sliding table module. BACKGROUND

[0002] The sliding table module is a linear motion device composed of a guide rail, a sliding block, a driving mechanism and a transmission mechanism, and is mainly used to realize high-precision and high-repetitive linear displacement. The sliding table module device is widely used on industrial platforms due to its linear movement characteristics.

[0003] During the movement of the sliding table, an effective sealing and shielding protection scheme is needed to completely isolate the internal parts of the sliding table (such as the guide rail, lead screw and other precision components) from the external environment, so as to achieve the protection purposes of dust prevention, debris prevention and liquid splash prevention, while keeping the appearance clean.

[0033] The existing slide module protection measures mainly have the following two kinds: the first telescopic protective sleeve form, using a telescopic rubber sleeve or an organ case (usually made of rubber, plastic or fabric) to cover both sides of the slide, due to its limited telescopic ratio, this scheme is not suitable for long-stroke occasions, or is strictly limited in selection, and the flexibility is insufficient. The second, steel belt type protection, a roll of stainless steel belt is used to shield above the slide. When the slide moves, the steel belt is unfolded or retracted. This scheme may be suitable for long-stroke, but this scheme has several disadvantages: complex structure, high manufacturing cost, difficult assembly, and the present application provides a slide module based on the above problems.

[0034] The slide module provided by the present application will be described in detail below in conjunction with specific embodiments.

[0035] Figure 1 The structure diagram of the slide module provided by the embodiment of the present application is shown in Figure 2 The structure diagram of the internal structure of the slide module provided by the embodiment of the present application is shown in Figure 5 The partial structure diagram of the slide seat of the slide module provided by the embodiment of the present application is shown in Figure 1 、 Figure 2 and Figure 5 The present application provides a slide module, which comprises a cover plate 1, a base 2, a slide seat 3 and a linear drive structure 4. The base 2 is provided with a guide rail 20. The linear drive structure 4 is used to drive the slide seat 3 to move on the guide rail 20. The cover plate 1 is covered on the base 2 and is used to shield the linear drive structure;

[0036] The cover plate 1 has a first slot and a second slot for the sliding of the sliding seat 3, the first slot is provided with a first shielding belt 5, the second slot is provided with a second shielding belt 6, along the sliding direction of the sliding seat 3, the two ends of the first shielding belt 5 are fixed with the two sides of the sliding seat 3, the two ends of the second shielding belt 6 are fixed with the two sides of the sliding seat 3, the first shielding belt 5 is driven to shield the first slot with the sliding of the sliding seat 3, the second shielding belt 6 is driven to shield the second slot with the sliding of the sliding seat 3.

[0037] The sliding table module of the embodiment is a linear motion mechanism commonly used in the field of automation industry, which can realize precise and repeated linear movement. The base 2 is provided with guide rails 20, for example, two guide rails 20 are provided, and the two guide rails 20 are fixed on the base 2 by bolts. The linear driving structure 4 is used to drive the sliding seat 3 to move on the guide rail 20. Exemplarily, the bottom of the sliding seat 3 is provided with a sliding block matched with the guide rail 20. The cooperation structure of the guide rail 20 and the sliding seat 3 of the embodiment adopts the prior art. The linear driving structure 4 of the embodiment is used to drive the sliding seat 3 to move on the guide rail 20. The specific structure of the linear driving structure 4 is not particularly limited in the embodiment, for example, the linear driving structure 4 of the embodiment is a commonly used screw rod driving structure or a synchronous belt driving structure.

[0038] The cover plate 1 of the embodiment is covered on the base 2. Exemplarily, the cover plate 1 includes a top cover plate 11, end cover plates 12 arranged at both ends of the base 2, and side cover plates 13 arranged between the two end cover plates 12. The end cover plates 12 and the side cover plates 13 are fixed on the base 2. The top cover plate 11 is fixed on the end cover plates 12. The side cover plates 13 include front and rear side cover plates (not shown in the figure). The cover plate 1 of the embodiment has a first slot and a second slot for the sliding of the sliding seat 3. The first slot of the embodiment is located between the top cover plate 11 and the front side cover plate, and the second slot is located between the top cover plate 11 and the rear side cover plate. The cover plate 1 of the embodiment is covered on the base 2, and the size of the cover plate 1 is matched with the size of the base 2. The size of the cover plate 1 and the base 2 is not particularly limited in the embodiment.

[0039] The first slot is provided with a first shielding belt 5, and the second slot is provided with a second shielding belt 6. In the sliding direction of the sliding seat 3, the two ends of the first shielding belt 5 are fixed to the two sides of the sliding seat 3, and the two ends of the second shielding belt 6 are fixed to the two sides of the sliding seat 3. The first shielding belt 5 is driven to shield the first slot along with the sliding of the sliding seat 3, and the second shielding belt 6 is driven to shield the second slot along with the sliding of the sliding seat 3. The existing protection measures of the slide module mainly include the following two kinds: the first is a telescopic protective sleeve form. A telescopic rubber sleeve or an organ cover (usually made of rubber, plastic or fabric) is used to cover the two sides of the slide. Since the telescopic ratio is limited, this protection method is not suitable for long-stroke occasions or is strictly limited when selecting, and the flexibility is insufficient. The second is a steel belt type protection. A stainless steel belt is used to shield above the slide. When the slide moves, the steel belt is unfolded or retracted. This protection method may be suitable for long-stroke, but this protection method has multiple disadvantages: complex structure, high manufacturing cost, and difficult assembly. In the reciprocating process of the sliding seat 3 of the slide module of the embodiment, the first shielding belt 5 is driven to seal the first slot along with the sliding of the sliding seat 3, and the second shielding belt 6 is driven to seal the second slot along with the sliding of the sliding seat 3. The cover plate 1 and the first shielding belt 5 and the second shielding belt 6 of the slide module can completely isolate the inside of the slide from the external environment, achieve the protection purpose of dust prevention, debris prevention, and liquid splash prevention, and the two ends of the first shielding belt 5 of the slide module are fixed to the two sides of the sliding seat 3, and the two ends of the second shielding belt 6 are fixed to the two sides of the sliding seat 3. The assembly method is simple.

[0040] The slide module of the embodiment includes a cover plate, a base, a sliding seat, and a linear driving structure. The base is provided with a guide rail, and the linear driving structure is used to drive the sliding seat to move on the guide rail. The cover plate is installed on the base to shield the linear driving structure. The cover plate has a first slot and a second slot for the sliding seat to slide. The first slot is provided with a first shielding belt, and the second slot is provided with a second shielding belt. In the sliding direction of the sliding seat, the two ends of the first shielding belt are fixed to the two sides of the sliding seat, and the two ends of the second shielding belt are fixed to the two sides of the sliding seat. The first shielding belt is driven to shield the first slot along with the sliding of the sliding seat, and the second shielding belt is driven to shield the second slot along with the sliding of the sliding seat. In the reciprocating process of the sliding seat of the slide module, the first shielding belt is driven to seal the first slot along with the sliding of the sliding seat, and the second shielding belt is driven to seal the second slot along with the sliding of the sliding seat. The cover plate and the first shielding belt and the second shielding belt of the slide module can completely isolate the inside of the slide from the external environment, achieve the protection purpose of dust prevention, debris prevention, and liquid splash prevention, and the sealing structure of the slide module is simple and easy to assemble.

[0041] Figure 3Please refer to the enlarged structural diagram of the mounting location of the first and second shielding belts of the slide module provided in this embodiment of the invention. Figures 1-3 Specifically, on the first slot side, along the sliding direction of the slide block 3, both ends of the base 2 are provided with first flat pulleys 21, and the first shielding belt 5 is wrapped around the outside of the first flat pulleys 21; on the second slot side, along the sliding direction of the slide block 3, both ends of the base 2 are provided with second flat pulleys 22, and the second shielding belt 6 is wrapped around the outside of the second flat pulleys 22. In this embodiment, the first shielding belt 5 is wrapped around the outside of the first flat pulley 21, and the second shielding belt 6 is wrapped around the outside of the second flat pulley 22. The flat pulleys in this embodiment define the running path of the shielding belt, ensuring that the shielding belt always moves on a defined trajectory parallel to the slot, without collapsing inward or excessively deviating. In this embodiment, the shielding belt slides on the flat pulleys, and its friction is rolling friction, which is much less than the sliding friction of the belt dragging directly on a stationary structure. This structure significantly reduces operating noise, frictional resistance, and belt wear, and extends the service life of the first shielding belt 5 and the second shielding belt 6.

[0042] Preferably, both the first flat pulley 21 and the second flat pulley 22 are convex pulleys with a higher center and lower sides. Exemplarily, in this embodiment, both the first flat pulley 21 and the second flat pulley 22 are rugby ball-shaped structures with a higher center and lower sides. During operation, the first shielding belt 5 and the second shielding belt 6 are prone to shifting to one side due to uneven tension, installation errors, or load changes, leading to increased wear or even detachment. The center diameter of the rugby ball-shaped idler pulley is slightly larger than the sides. When the first shielding belt 5 and the second shielding belt 6 are biased to one side, the linear velocity at the contact point on that side will be slightly higher than on the other side due to the larger diameter, causing the belt to experience a frictional force pushing it back towards the center, thus achieving automatic correction. If the flat pulley is a pure cylinder, the first shielding belt 5 and the second shielding belt 6 may experience greater pressure on local edges due to slight shifts during operation, accelerating wear. The central convex structure of this embodiment slightly arches the belt contact surface, distributing pressure more evenly in the central area, reducing edge stress concentration, and extending the lifespan of the first shielding belt 5 and the second shielding belt 6, the first flat pulley 21, and the second flat pulley 22.

[0043] In a specific embodiment, the first shielding belt 5 and the second shielding belt 6 are fixed to the sliding seat 3 through sheet metal parts 23. In this embodiment, the first shielding belt 5 and the second shielding belt 6 are fixed to the sliding seat 3 through sheet metal parts 23, and the belts are always in tension during operation. The sheet metal parts 23 provide a large and solid connection area, which can more evenly disperse and transmit the tension of the belts to the main structure of the sliding seat 3. If the belts are directly fixed to the sliding seat 3 at a point, stress concentration will occur, which may damage the structure of the sliding seat 3 or the connection of the belts. In this embodiment, the sheet metal parts 23 act as a transition piece to effectively protect the core structure of the sliding seat 3. For example, the sheet metal part 23 in this embodiment is L-shaped, one end of the L-shaped sheet metal part is fixed to the first shielding belt 5, and the second end of the sheet metal part 23 is fixed to the sliding seat 3 by screws. The fixing method of the first shielding belt 5 is the same as that of the first shielding belt 5.

[0044] Further, the fixing positions of the first shielding belt 5 and the second shielding belt 6 to the sliding seat 3 are provided with first tensioning structures for adjusting the tension of the first shielding belt 5 and the second shielding belt 6.

[0045] In the above embodiment, the cover plate 1 includes a top cover plate 11, end cover plates 12 arranged at both ends of the base 2, and side cover plates 13 arranged between the two end cover plates 12. The end cover plates 12 and the side cover plates 13 are fixed to the base 2, and the top cover plate 11 is fixed to the end cover plates 12. The end cover plates 12 at both ends of the base 2 can shield the ends of the base 2. In this embodiment, the first slot and the second slot are arranged on the two side cover plates 13. When internal structures need to be repaired, only the top cover plate 11 needs to be removed to access most of the core components inside, without the need to disassemble the entire cover plate 1. The top cover plate 11, the end cover plates 12, the side cover plates 13, the first shielding belt 5 at the first slot, and the second shielding belt 6 at the second slot can prevent external foreign matter (such as dust and light sources) from entering the inside of the sliding table module, and protect the internal moving parts from interference or damage.

[0046] Please refer to Figure 1 , Figure 2In a specific embodiment, the linear drive structure 4 comprises a drive motor 41, a drive pulley 42 and a transmission belt 43. The drive pulley 42 is arranged at the output end of the drive motor 41, which is fixed to the sliding base 3. The two ends of the transmission belt 43 are fixed to the two ends of the guide rail 20 respectively. The drive pulley 42 is engaged with the transmission belt 43, so as to make the sliding base 3 slide along the longitudinal direction of the guide rail 20. In the traditional scheme of the existing slide module, the motor is fixed, the belt or the lead screw is driven, and the sliding base 3 is dragged. The linear drive structure 4 of the present embodiment only needs a fixed transmission belt 43 at both ends, a drive motor 41 and a drive pulley 42. The structure is extremely simple, the number of parts is greatly reduced, and the material cost, processing cost and assembly cost are directly reduced. At the same time, fewer parts mean higher system reliability and lower failure rate. The drive motor 41 is installed on the sliding base 3 through the motor flange, and the drive pulley 42 is directly engaged with the fixed transmission belt 43. The power transmission path is extremely short. The linear drive structure 4 of the present embodiment is simple to assemble. Only the drive motor needs to be installed on the sliding base 3, and then the two ends of the transmission belt 43 need to be tensioned and fixed at the two ends of the guide rail 20. The position of the drive motor 41 automatically determines the engagement point, and there is no problem of coaxiality calibration. The technical requirements for the assembly personnel are reduced. When the transmission belt 43 needs to be replaced, only the fixing device at both ends needs to be loosened, a new transmission belt 43 needs to be replaced and tensioned again.

[0047] Further, the linear drive structure 4 further comprises two idlers 44 arranged on both sides of the drive pulley 42 to increase the wrap angle of the transmission belt 43 on the drive pulley 42. In the traditional fixed motor drive, the belt wraps around the drive pulley at a large angle (usually close to 180°) to increase the contact area and friction. The two idlers 44 of the present embodiment press the fixed transmission belt 43 towards the drive pulley 42 from both sides, forcing the transmission belt 43 to wrap around the drive pulley 42 at a larger angle. The two idlers 44 of the present embodiment are fixed on the motor flange. The greater the wrap angle of the transmission belt 43 on the drive pulley 42, the greater the contact area between the transmission belt 43 and the drive pulley 42 and the static friction generated. The arrangement of the idlers 44 ensures that the torque output by the drive motor 41 can be effectively transmitted to the transmission belt 43, thereby converting into the force to push the sliding base 3 to move. Especially when starting, accelerating, decelerating or bearing load, the huge friction can effectively avoid the phenomenon of slipping and ensure the accuracy of transmission.

[0048] Preferably, please refer to Figure 2 and Figure 4The two ends of the transmission belt 43 are fixed to the mounting seat 24 through the toothed plate 26. The toothed plate 26 is precisely machined with meshing teeth matched with the tooth shape of the transmission belt 43 on the side facing the transmission belt 43, and the end of the transmission belt 43 is precisely tooth-shapedly embedded with the toothed plate 26. The toothed plate 26 is provided with a connecting through hole, and the toothed plate 26 and the end of the transmission belt 43 are firmly locked on the mounting seat 24 by sequentially penetrating the connecting through hole and the corresponding threaded hole of the mounting seat 24 through a fastener. The two ends of the transmission belt 43 are fixed to the mounting seat 24 through the toothed plate 26, realizing high-strength, high-precision and lossless fixing of the end of the transmission belt 43, and the meshing tooth structure ensures that the tension of the transmission belt 43 is uniformly transmitted through the tooth surface, avoiding the extrusion deformation and internal damage of the transmission belt 43 caused by the compression of ordinary clamps, greatly prolonging the service life of the transmission belt 43. At the same time, this fixing method fundamentally eliminates the possibility of any slip or creep of the transmission belt 43 at the fixed end, ensuring the long-term stability of the synchronization accuracy of the entire transmission system.

[0049] The linear driving structure 4 of the embodiment comprises a driving motor 41, a driving pulley 42, a transmission belt 43 and two idlers 44. The driving motor 41 is directly fixed and installed on the bottom plate of the sliding seat 3 through a motor flange, and the driving pulley 42 is installed on the output shaft of the driving motor 41. The two idlers 44 are installed on the two sides of the driving pulley 42 through the above-mentioned motor flange, which functions to increase the wrap angle of the transmission belt 43 on the driving pulley 42 and prevent transmission slip. The two ends of the transmission belt 43 are fixed to the two ends of the guide rail 20 through the mounting seat 24. The mounting seat 24 is provided with meshing teeth matched with the tooth shape of the transmission belt 43 for firmly fixing the transmission belt 43. When the driving motor 41 works, the driving pulley 42 rotates and generates a reaction force through the meshing with the fixed transmission belt 43, thereby driving the entire sliding seat 3 to move along the guide rail 20 together with the driving motor 41.

[0050] Further, the transmission belt 43 has a second tensioning structure for adjusting the tension of the transmission belt 43.

[0051] Figure 4 The structure diagram of the second tensioning structure of the sliding table module provided by the embodiment of the application is shown in Figures 1-4, specifically, the second tensioning structure comprises a waist-shaped hole 25 opened in the bottom of the base 2 and a mounting hole 14 opened in the side of the cover plate 1 for adjusting the position of the mounting seat 24, the mounting seat 24 is connected with the cover plate 1 through bolts or screws, so as to adjust the position of the mounting seat 24 through the bolts or screws, thereby adjusting the tension of the transmission belt 43. The tensioning structure of the transmission belt 43 in the embodiment is modularized to a separate mounting seat 24 plus waist-shaped hole 25 structure, and adjusting the tension only needs to operate this module, which does not affect other components such as the driving motor 41, the sliding seat 3 and the shielding structure of the sliding table. The operator can accurately fine-tune the position of the mounting seat 24 through the waist-shaped hole 25, so as to realize fine control of the tension of the transmission belt 43, and ensure that the tension is just right, not too loose to cause slipping, not too tight to increase wear and energy consumption. The mounting hole 14 through which the bolt / screw is opened in the side of the cover plate 1, the adjustment interface is exposed outside, and the user or maintenance personnel can directly perform the tensioning operation without opening the cover plate 1, and when the transmission belt 43 naturally elongates and loosens after long-term operation of the equipment, the on-site adjustment can be quickly performed, minimizing downtime.
