Description

Technical Field

[0001] This invention relates to the field of electromechanical equipment technology, and more specifically to a slide module. Background Technology

[0002] A slide module is a linear motion device consisting of a guide rail, a slider, a drive mechanism, and a transmission mechanism. It is primarily used to achieve high-precision, highly repeatable linear displacement. Due to its linear movement characteristics, slide module devices are widely used on machine tools in industrial applications.

[0003] During the movement of the slide table, an effective sealing and shielding protection scheme is needed to completely isolate the interior of the slide table (such as precision components like guide rails and lead screws) from the external environment, so as to achieve the protection against dust, chips, and liquid splashes, while maintaining a clean appearance.

[0004] Existing protective measures for slide modules mainly fall into two categories: First, telescopic protective sleeves, which use retractable rubber sleeves or bellows covers (usually made of rubber, plastic, or fabric) to cover both sides of the slide. Due to their limited telescopic ratio, this solution is unsuitable for long-stroke applications or is subject to strict limitations in selection, lacking flexibility. Second, steel belt protection, which uses a roll of stainless steel belt to shield the slide. As the slide moves, the steel belt unfolds or retracts. This solution may be suitable for long strokes, but it has several drawbacks: complex structure, high manufacturing cost, and difficult assembly. Summary of the Invention

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0024] Existing protective measures for slide table modules mainly fall into two categories: First, telescopic protective sleeves, which use retractable rubber sleeves or bellows covers (usually made of rubber, plastic, or fabric) to cover both sides of the slide table. Due to their limited telescopic ratio, this solution is unsuitable for long-stroke applications or is subject to strict limitations in selection, lacking flexibility. Second, steel strip protection, which uses a roll of stainless steel strip for shielding above the slide table. As the slide table moves, the steel strip unfolds or retracts. This solution may be suitable for long strokes, but it has several drawbacks: complex structure, high manufacturing cost, and difficult assembly. This application addresses these issues by providing a slide table module.

[0025] The slide module provided by the present invention will be described in detail below with reference to specific embodiments.

[0026] Figure 1 This is a schematic diagram of the structure of the slide module provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the internal structure of the slide module provided in an embodiment of the present invention after removing the outer shell. Figure 5 Please refer to the schematic diagram of a partial structure of the slide block of the slide module provided in the embodiment of the present invention. Figure 1 , Figure 2 and Figure 5 This invention provides a sliding module, including a cover plate 1, a base 2, a slide block 3, and a linear drive structure 4. The base 2 is provided with a guide rail 20, and the linear drive structure 4 is used to drive the slide block 3 to move on the guide rail 20. The cover plate 1 is placed on the base 2 to cover the linear drive structure. The cover plate 1 has a first slot and a second slot for the sliding block 3 to slide. A first shielding belt 5 is provided at the first slot, and a second shielding belt 6 is provided at the second slot. Along the sliding direction of the sliding block 3, the two ends of the first shielding belt 5 are fixed to the two sides of the sliding block 3, and the two ends of the second shielding belt 6 are fixed to the two sides of the sliding block 3. The first shielding belt 5 is driven by the sliding block 3 to shield the first slot, and the second shielding belt 6 is driven by the sliding block 3 to shield the second slot.

[0027] The slide module in this embodiment is a linear motion mechanism commonly used in the field of automated industry, which can achieve precise and repetitive linear movement. The base 2 in this embodiment is provided with guide rails 20, for example, two guide rails 20 are provided, and the two guide rails 20 are fixed to the base 2 by bolts. The linear drive structure 4 is used to drive the slide 3 to move on the guide rails 20. Exemplarily, the bottom of the slide 3 is provided with a slider that matches the guide rail 20. The mating structure between the guide rail 20 and the slide 3 in this embodiment adopts existing technology. The linear drive structure 4 in this embodiment is used to drive the slide 3 to move on the guide rail 20. This embodiment does not impose any special limitations on the specific structure of the linear drive structure 4. For example, the linear drive structure 4 in this embodiment is a commonly used lead screw drive structure or a synchronous belt drive structure.

[0028] In this embodiment, the cover plate 1 is mounted on the base 2. Exemplarily, the cover plate 1 includes a top cover plate 11, end cover plates 12 disposed at both ends of the base 2, and a side cover plate 13 disposed between the two end cover plates 12. Both the end cover plates 12 and the side cover plates 13 are fixed to the base 2. The top cover plate 11 is fixed to the end cover plates 12, and the side cover plate 13 includes a front side cover plate and a rear side cover plate (not shown in the figure). The cover plate 1 in this embodiment has a first slot and a second slot for sliding the slide block 3. The first slot 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. In this embodiment, the cover plate 1 is mounted on the base 2, and the size of the cover plate 1 is adapted to the size of the base 2. This embodiment does not impose any special limitations on the dimensions of the cover plate 1 and the base 2.

[0029] In this embodiment, a first shielding belt 5 is provided at the first slot and a second shielding belt 6 is provided at the second slot. Along the sliding direction of the slide block 3, the two ends of the first shielding belt 5 are fixed to the two sides of the slide block 3, and the two ends of the second shielding belt 6 are fixed to the two sides of the slide block 3. The first shielding belt 5 is driven by the sliding of the slide block 3 to shield the first slot, and the second shielding belt 6 is driven by the sliding of the slide block 3 to shield the second slot. The existing slide block module protection measures are mainly of the following two types: the first is the form of a retractable protective sleeve, which uses a retractable rubber sleeve or accordion cover (usually made of rubber, plastic or fabric) to cover the two sides of the slide block. Due to its limited retraction ratio, this protection method is not suitable for long stroke occasions, or is strictly limited in selection, and lacks flexibility. The second type is steel strip protection, which uses a roll of stainless steel strip to shield the slide table. When the slide table moves, the steel strip unfolds or retracts accordingly. This protection method may be suitable for long strokes, but it has several drawbacks: complex structure, high manufacturing cost, and difficult assembly. In this embodiment, during the reciprocating motion of the slide table module, the first shielding belt 5 moves with the slide table 3 to seal the first slot, and the second shielding belt 6 moves with the slide table 3 to seal the second slot. The cover plate 1 of the slide table module, as well as the first shielding belt 5 and the second shielding belt 6, can completely isolate the inside of the slide table from the external environment, achieving the purpose of dustproof, chipproof, and liquid splashproof protection. Moreover, the two ends of the first shielding belt 5 and the two ends of the second shielding belt 6 are fixed to the two sides of the slide table 3, making the assembly method simple.

[0030] The slide module of this embodiment includes a cover plate, a base, a slide block, and a linear drive structure. A guide rail is provided on the base, and the linear drive structure is used to drive the slide block to move on the guide rail. The cover plate is installed on the base to shield the linear drive structure. The cover plate has a first slot and a second slot for the slide block to slide. A first shielding belt is provided at the first slot, and a second shielding belt is provided at the second slot. Along the sliding direction of the slide block, the two ends of the first shielding belt are fixed to the two sides of the slide block, and the two ends of the second shielding belt are fixed to the two sides of the slide block. The first shielding belt moves with the sliding of the slide block to shield the first slot, and the second shielding belt moves with the sliding of the slide block to shield the second slot. During the reciprocating motion of the slide block of this slide module, the first shielding belt moves with the slide block to seal the first slot, and the second shielding belt moves with the slide block to seal the second slot. The cover plate of this slide module, as well as the first and second shielding belts, can completely isolate the inside of the slide block from the external environment, achieving the purpose of dustproof, chipproof, and liquid splashproof protection. Moreover, the sealing structure of this slide module is simple and easy to assemble.

[0031] 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. Figure 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.

[0032] 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.

[0033] In one specific embodiment, both the first shielding belt 5 and the second shielding belt 6 are fixed to the slide block 3 via sheet metal parts 23. In this embodiment, the first shielding belt 5 and the second shielding belt 6 are fixed to the slide block 3 via sheet metal parts 23. The belts are always under tension during operation. The sheet metal parts 23 provide a large and robust connection area, which can more evenly distribute and transfer the tension borne by the belt to the main structure of the slide block 3. If the belt is directly fixed to a single point on the slide block 3 body, it will lead to stress concentration, and there is a risk of damage to the slide block 3 structure or the belt connection point under long-term operation. In this embodiment, the sheet metal parts 23 act as a transition component, effectively protecting the core slide block 3 structure. Exemplarily, the sheet metal parts 23 in this embodiment are L-shaped. One end of the L-shaped sheet metal parts is fixed to the first shielding belt 5, and the second end of the sheet metal parts 23 is fixed to the slide block 3 with screws. The fixing method of the first shielding belt 5 is the same as that of the first shielding belt 5.

[0034] Furthermore, a first tensioning structure is provided at the fixing point between the first shielding belt 5 and the slide 3, and at the fixing point between the second shielding belt 6 and the slide 3. The first tensioning structure is used to adjust the tension of the first shielding belt 5 and the tension of the second shielding belt 6.

[0035] In the above embodiment, the cover plate 1 includes a top cover plate 11, end cover plates 12 disposed at both ends of the base 2, and a side cover plate 13 disposed between the two end cover plates 12. The end cover plates 12 and the side cover plates 13 are both fixed to the base 2, and the top cover plate 11 is fixed to the end cover plates 12. The end cover plates 12 located at both ends of the base 2 can shield both ends of the base 2. In this embodiment, the first slot and the second slot are respectively disposed on the two side cover plates 13. When it is necessary to inspect the internal structure, it is only necessary to remove the top cover plate 11 to access most of the internal core components without disassembling the entire cover plate 1. In this embodiment, the top cover plate 11, end cover plate 12, side cover plate 13, as well as the first shielding belt 5 located at the first slot and the second shielding belt 6 located at the second slot can prevent external foreign objects (such as dust and light sources) from entering the slide module and protect the internal moving parts from interference or damage.

[0036] Please see Figure 1 , Figure 2In one specific embodiment, the linear drive structure 4 includes a drive motor 41, a drive pulley 42, and a transmission belt 43. The drive pulley 42 is disposed at the output end of the drive motor 41, and the drive motor 41 is fixed to the slide block 3. The two ends of the transmission belt 43 are respectively fixed to the two ends of the guide rail 20. The drive pulley 42 meshes with the transmission belt 43 to allow the slide block 3 to slide longitudinally along the guide rail 20. Traditional solutions for existing slide block modules involve a fixed motor and a moving belt or lead screw to drag the slide block 3. The linear drive structure 4 of this embodiment only requires a transmission belt 43 fixed at both ends, a drive motor 41, and a drive pulley 42, resulting in an extremely simple structure and a significant reduction in the number of parts, directly lowering material, processing, and assembly costs. Furthermore, fewer parts mean higher system reliability and a lower failure rate. In this embodiment, the drive motor 41 is mounted on the slide block 3 via a motor flange, and the drive pulley 42 directly meshes with the fixed transmission belt 43, resulting in a very short power transmission path. The linear drive structure 4 in this embodiment is simple to assemble. Simply install the drive motor on the slide 3, and then tighten and fix the two ends of the transmission belt 43 at both ends of the guide rail 20. The position of the drive motor 41 automatically determines the meshing point, eliminating the problem of coaxiality calibration and reducing the technical requirements for assembly personnel. When the transmission belt 43 needs to be replaced, simply loosen the fixing devices at both ends, replace it with a new transmission belt 43, and re-tighten it.

[0037] Furthermore, the linear drive structure 4 also includes two idler pulleys 44 disposed on both sides of the drive pulley 42 to increase the wrap angle of the transmission belt 43 on the drive pulley 42. In conventional fixed motor drives, the belt wraps around the drive pulley at a large angle (usually close to 180°) to increase the contact area and friction. In this embodiment, the two idler pulleys 44 press the fixed transmission belt 43 against the drive pulley 42 from both sides, forcing the transmission belt 43 to wrap around the drive pulley 42 at a larger angle. In this embodiment, the two idler pulleys 44 are fixed to the aforementioned motor flange. The larger the wrap angle of the transmission belt 43 on the drive pulley 42 in this embodiment, the greater the contact area and the static friction generated between the transmission belt 43 and the drive pulley 42. The idler pulleys 44 ensure that the torque output by the drive motor 41 can be effectively transmitted to the transmission belt 43, thereby converting it into a force that pushes the slide 3 to move. Especially during startup, acceleration, deceleration, or when under load, the huge friction can effectively prevent slippage and ensure the accuracy of transmission.

[0038] Preferably, please refer to Figure 2 and Figure 4The guide rail 20 has mounting seats 24 at both ends, which are fixed to the base 2. The two ends of the transmission belt 43 are fixed to the mounting seats 24 via toothed plates 26. In this embodiment, the two ends of the transmission belt 43 are fixed to the mounting seats 24 via toothed plates 26. The toothed plates 26 have precision-machined meshing teeth on the side facing the transmission belt 43 that match the tooth profile of the transmission belt 43. The ends of the transmission belt 43 achieve precise tooth profile engagement with the toothed plates 26 through the meshing teeth. The toothed plates 26 are provided with connecting through holes. Fasteners are passed through the connecting through holes and the corresponding threaded holes on the mounting seats 24 in sequence to firmly lock the toothed plates 26 and the ends of the transmission belt 43 onto the mounting seats 24. Both ends of the transmission belt 43 are fixed to the mounting base 24 by toothed plates 26, achieving high-strength, high-precision, and damage-free fixing of the ends of the transmission belt 43. Its meshing tooth structure ensures that the tension of the transmission belt 43 is evenly transmitted through the tooth surface, avoiding the squeezing deformation and internal damage that may occur with ordinary clamps, thus greatly extending the service life of the transmission belt 43. At the same time, this fixing method fundamentally eliminates any possibility of slippage 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.

[0039] The linear drive structure 4 of this embodiment includes a drive motor 41, a drive pulley 42, a transmission belt 43, and two idler pulleys 44. The drive motor 41 is directly fixed to the base plate of the slide 3 via a motor flange, and the drive pulley 42 is mounted on the output shaft of the drive motor 41. The two idler pulleys 44 are mounted on both sides of the drive pulley 42 via the aforementioned motor flange, and their function is to increase the wrap angle of the transmission belt 43 on the drive pulley 42 to prevent transmission slippage. The two ends of the transmission belt 43 are fixed to the two ends of the guide rail 20 via mounting seats 24. The mounting seats 24 are provided with meshing teeth that engage with the tooth profile of the transmission belt 43 to securely fix the transmission belt 43. When the drive motor 41 is working, the drive pulley 42 rotates, and through meshing with the stationary transmission belt 43, it generates a reaction force, thereby driving the entire slide 3, together with the drive motor 41, to move along the guide rail 20.

[0040] Furthermore, the transmission belt 43 has a second tensioning structure for adjusting the tension of the transmission belt 43.

[0041] Figure 4 Please refer to the structural diagram of the second tensioning structure of the slide module provided in the embodiment of the present invention. Figures 1-4Specifically, the second tensioning structure includes an oblong hole 25 at the bottom of the base 2 and a mounting hole 14 on the side of the cover plate 1 for adjusting the position of the mounting seat 24. The mounting seat 24 is connected to the cover plate 1 by bolts or screws, so that the tension of the transmission belt 43 can be adjusted by adjusting the position of the mounting seat 24. In this embodiment, the tensioning structure of the transmission belt 43 is modularized into an independent mounting seat 24 and oblong hole 25 structure. Adjusting the tension only requires operating this module and does not affect other components of the slide, such as the drive motor 41, the slide 3, and the shielding structure. The operator can precisely fine-tune the position of the mounting seat 24 through the oblong hole 25, thereby achieving fine control of the tension of the transmission belt 43, ensuring that the tension is just right, neither too loose to cause slippage nor too tight to increase wear and energy consumption. The mounting holes 14 for bolts / screws are opened on the side of the cover plate 1, and the adjustment interface is exposed to the outside. Users or maintenance personnel can directly perform tensioning operations without opening the cover plate 1. When the transmission belt 43 naturally elongates and becomes loose after long-term operation of the equipment, on-site adjustment can be carried out quickly to minimize downtime.

[0042] Figure 5 Please refer to the schematic diagram of a partial structure of the slide block of the slide module provided in the embodiment of the present invention. Figure 1 and 5 In one specific embodiment, the slide block 3 includes a base plate 31 and a side plate 32 perpendicularly disposed to the base plate 31. The side plate 32 is disposed along the longitudinal direction of the base 2. The length of the base plate 31 in the transverse direction of the base 2 is greater than the width of the base 2. A mounting plate 33 is disposed on the side plate 32, and the mounting plate 33 is used for external mounting components. Figure 6 This is a structural diagram of a slide module on which robot A is installed. Figure 6 The mounting component is robot A. In this embodiment, the base plate 31 has two side plates 32 perpendicular to it. A mounting plate 33 is connected to the two side plates 32. In this embodiment, the height of the side plates 32 in the vertical direction is greater than the height of the cover plate 1. The length of the base plate 31 in the transverse direction of the base 2 is greater than the width of the base 2, ensuring that even when installing heavy or long-arm actuators (such as robot arms, pneumatic fingers, and cameras), the entire system can maintain stable and precise movement and will not twist due to insufficient rigidity.

[0043] Furthermore, the side plate 32 is provided with a first cable passage hole 311, and the mounting plate 33 is provided with a second cable passage hole 331. The second cable passage hole 331 is located in the middle of the mounting plate 33 or near the edge of the mounting plate 33. In this embodiment, by providing cable passage holes on the side plate 32 and the mounting plate 33, a laying path is provided for the cable, guiding the cable to move with the slide 3 in the most reasonable way. In this embodiment, the first cable passage hole 311 and the second cable passage hole 331 are deburred and rounded to avoid sharp edges cutting the cable sheath, greatly extending the cable life. Optionally, the second cable pass-through hole 331 in this embodiment is located in the middle of the mounting plate 33 or near the edge of the mounting plate 33. For example, the second cable pass-through hole 331 located in the middle of the mounting plate 33 is suitable when the interface of the load (such as a robot or vision camera) is also in the middle. The cable can be connected from the back of the load in the shortest and most direct way, which can ensure that the cable is neat and the bending radius of the cable is also the smallest. For example, the second cable pass-through hole 331 located near the edge of the mounting plate 33 makes it easier for the cable to converge to one side of the equipment frame, instead of piling up in the center of the mounting plate 33 and interfering with the installation or operation of the load.

[0044] Please see Figure 1 and Figure 5 In one specific embodiment, the slide module further includes a reversing module 7, which includes a platform 71 and a drive structure. The drive structure is used to drive the platform 71 to rotate and is fixed to the mounting plate 33. In this embodiment, by setting the reversing module 7, products placed on the platform 71 can achieve a reversing function. The cable of the drive structure of the reversing module 7 in this embodiment can be managed in a standardized manner through the first cable guide hole 311 and the second cable guide hole 331, along with the cable of the slide module itself, without the need for additional messy wiring. Exemplarily, the platform 71 in this embodiment is a perforated plate base.

[0045] Please see Figure 2 In one specific embodiment, the slide module further includes an I / O module 8. The slide module of this embodiment integrates the I / O module 8, which, by collecting sensor data in real time, can precisely control the lifting, lowering, and walking movements of the equipment, ensuring operational stability and accuracy. Simultaneously, the I / O module 8 can support adding or removing functions as needed, helping the equipment achieve customized upgrades and adapt to different working scenarios.

[0046] The slide module of this invention includes a cover plate, a base, a slide block, and a linear drive structure. A guide rail is provided on the base, and the linear drive structure is used to drive the slide block to move on the guide rail. The cover plate is installed on the base to shield the linear drive structure. The cover plate has a first slot and a second slot for the slide block to slide. A first shielding belt is provided at the first slot, and a second shielding belt is provided at the second slot. Along the sliding direction of the slide block, the two ends of the first shielding belt are fixed to the two sides of the slide block, and the two ends of the second shielding belt are fixed to the two sides of the slide block. The first shielding belt slides with the slide block to shield the first slot, and the second shielding belt slides with the slide block to shield the second slot. During the reciprocating motion of the slide block in this slide module, the first shielding belt moves with the slide block, sealing the first slot. The second shielding belt moves with the slide block, sealing the second slot. The cover plate, along with the first and second shielding belts, completely isolates the interior of the slide block from the external environment, achieving protection against dust, chips, and liquid splashes. Furthermore, the sealing structure of this slide module is simple and easy to assemble.
