Description

Technical Field

[0001] This utility model relates to a belt module with high load and long stroke. Background Technology

[0002] In the automation industry, linear modules (such as lead screw linear modules and belt linear modules) are one of the commonly used mechanical equipment in automation equipment. Linear modules have different names in different industries. Common names include: linear slide, linear table, electric slide, robotic arm, etc. A slide is usually installed on a linear module. Other required workpieces are installed on the slide, and a set of forward and reverse motor programs are set to realize the automatic cyclic reciprocating motion of the workpiece, thereby achieving the purpose of mass production and intensive production.

[0003] Belt linear modules have advantages such as high load capacity, high transmission speed, high transmission accuracy, and long stroke, and are widely used in automated production lines, CNC machine tools, 3D printers, and other equipment. In existing belt linear modules, a top cover is installed between the two end caps of the belt linear module to achieve protection, support, and safety. The top cover is located above the slide, and the reciprocating movement of the slide does not interfere with the top cover. However, in belt linear modules with high load and long stroke, the stroke can generally reach more than 2.3 meters, causing the middle part of the top cover to sag due to its own weight, resulting in greater noise during slide operation. In some belt linear modules with high load and long stroke, rollers are installed between the top cover and the top of the slide to improve the problem of the top cover sagging. The rollers are installed on the top of the slide to provide some support for the top cover and improve the sagging problem to a certain extent. However, the presence of rollers between the slide and the top cover will cause a lot of friction noise during the reciprocating movement of the slide, resulting in a poor user experience, especially in applications where noise is a concern. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a belt module with a large load and long stroke.

[0005] According to one aspect of the present invention, a high-load, long-stroke belt module is provided, comprising: The belt module body has mounting bases on the inner sides of both end caps. Adjustment element, the adjustment element is located on the top of the mounting base; and The steel strip has one end mounted on an adjusting element. The position of the adjusting element on the mounting base can be adjusted along the length of the steel strip. One end of the steel strip is mounted on one mounting base via the adjusting element, and the other end of the steel strip is mounted on another mounting base.

[0006] The belt module of this utility model allows the adjusting component on the mounting base to be adjusted along the length of the steel belt, thereby tautling the steel belt outward along its length. In belt modules with large loads and long strokes, the middle part of the steel belt will not sag due to its own weight. The steel belt replaces the upper cover structure in existing straight belt modules, avoiding the problem of upper cover sagging during long strokes, effectively reducing the noise of the slide table during operation, and providing users with a quiet user experience. It is suitable for use scenarios where noise is a requirement.

[0007] Preferably, there are two adjusting components, which are respectively located on the top of two mounting seats. One end of the steel strip is located on the adjusting component on the top of one mounting seat, and the other end of the steel strip is located on the adjusting component on the top of the other mounting seat.

[0008] Therefore, the two adjusting components can simultaneously tighten both ends of the steel belt outward along its length, ensuring that even in long-stroke belt modules, the middle of the steel belt will not sag due to its own weight.

[0009] Preferably, it also includes a first adjusting screw and a second adjusting screw. The adjusting component is provided with an elongated oval adjusting hole. The end of the first adjusting screw passes through the elongated oval adjusting hole and is screwed onto the top of the mounting base. The end of the second adjusting screw passes through the end cap of the belt module body and is screwed into the adjusting component. The length direction of the elongated oval adjusting hole is parallel to the length direction of the steel belt.

[0010] Therefore, when installing the steel strip, first install the adjusting component on the mounting base using the first adjusting screw. The first adjusting screw does not need to be tightened at first. Then, fix the end of the steel strip to the adjusting component. Since the oblong adjusting hole for installing the first adjusting screw is oblong in shape, the adjusting component will move outward along the length of the steel strip to straighten the steel strip during the tightening of the second adjusting screw. When the steel strip is taut, tighten the first adjusting screw. The assembly of the steel strip is very simple, and the middle position of the assembled steel strip will not sag due to its own weight.

[0011] Preferably, the end cap is provided with a through hole, and the end of the second adjusting screw passes through the through hole and is screwed into the adjusting component. The axis of the through hole is arranged perpendicular to the axis of the oblong adjusting hole.

[0012] Therefore, during the process of tightening the second adjusting screw on the end cap, the adjusting component will move outward along the length of the steel strip to straighten the steel strip. The perpendicular arrangement of the axis of the through hole and the axis of the oblong adjusting hole ensures that the adjusting component will move smoothly outward along the length of the steel strip during the process of tightening the second adjusting screw.

[0013] Preferably, there are at least two first adjusting screws and two second adjusting screws. The end of at least one first adjusting screw passes through an elongated adjusting hole on an adjusting member and is screwed onto the top of a mounting base. The end of at least one first adjusting screw passes through an elongated adjusting hole on another adjusting member and is screwed onto the top of another mounting base. The end of at least one second adjusting screw passes through one end cap of the belt module body and is screwed into an adjusting member. The end of at least one second adjusting screw passes through another end cap of the belt module body and is screwed into another adjusting member.

[0014] Therefore, the two adjusting components are respectively mounted on the corresponding mounting base by at least one first adjusting screw, and the two adjusting components can be moved along the length direction of the steel strip by at least one second adjusting screw.

[0015] Preferably, the number of elongated oval adjustment holes on the adjusting member is four, and the number of first adjusting screws is eight. The ends of four first adjusting screws pass through the four elongated oval adjustment holes on one adjusting member and are screwed onto the top of a mounting base. The ends of the other four first adjusting screws pass through the four elongated oval adjustment holes on another adjusting member and are screwed onto the top of another mounting base.

[0016] Therefore, the adjusting component can be securely installed on the mounting base by the four first adjusting screws. After the four first adjusting screws on the adjusting component are tightened, the steel belt can maintain a stable tension.

[0017] Preferably, there are six second adjusting screws. The ends of three second adjusting screws pass through one end cap of the belt module body and are screwed into an adjusting member, while the ends of the other three second adjusting screws pass through another end cap of the belt module body and are screwed into another adjusting member.

[0018] Therefore, each adjusting component can be securely locked to the end cap of the belt module body by three second adjusting screws, ensuring that the steel belt can maintain a stable tension.

[0019] Preferably, the adjusting member has a stepped portion, one end of the steel strip is located in the stepped portion of one adjusting member, and the other end of the steel strip is located in the stepped portion of another adjusting member.

[0020] Therefore, installing the end of the steel strip in the stepped part of the adjusting component can ensure that the top of the steel strip is flush with the top of the adjusting component or that the top of the steel strip does not protrude from the top of the adjusting component. This can avoid interference between the protruding top of the steel strip and other components, and also improve the aesthetics of the belt module.

[0021] Preferably, it further includes two fixing strips and at least two fixing screws, with the end of at least one fixing screw passing through one end of a fixing strip and a steel strip in sequence and then screwed into a step portion on an adjusting member, and the end of at least one fixing screw passing through the other end of another fixing strip and a steel strip in sequence and then screwed into a step portion on another adjusting member.

[0022] Therefore, the end of the steel strip can be installed in the stepped part of the adjusting part by means of a fixing strip and fixing screws.

[0023] Preferably, the sum of the thickness of the fixing strip and the thickness of the steel strip is equivalent to the longitudinal depth of the step.

[0024] Therefore, this ensures that the top of the fixing bar is flush with the top of the adjusting component, and the top of the steel strip is lower than the top of the adjusting component. This avoids interference between the protruding fixing bar and the top of the steel strip and other components, and also improves the aesthetics of the belt module. Attached Figure Description

[0028] See Figures 1 to 6 A high-load, long-stroke belt module includes a belt module body 1, an adjusting component 2, a steel belt 3, a first adjusting screw 4, a second adjusting screw 5, a fixing bar 6, and a fixing screw 7.

[0029] See Figure 1 and Figure 2 The belt module body 1 includes a base, a motor 101, a slide 102, a driven pulley 103, a drive pulley mounting base 104, and a timing belt 105. A drive pulley (not shown) is mounted in the drive pulley mounting base 104. The drive pulley mounting base 104 is fixed to the outer wall of one end cover 11 of the belt module body 1. The motor 101 drives the drive pulley inside the drive pulley mounting base 104 to rotate. The drive pulley inside the drive pulley mounting base 104 is connected to the driven pulley 103 via the timing belt 105, which passes through the end cover 11 where the drive pulley mounting base 104 is mounted. Driven wheel 103 is mounted on mounting base 12 on the inner wall of another end cover 11. Driven wheel 103 can rotate on mounting base 12. The two sides of slide table 102 are slidably mounted on the top of the two side walls of the base. The bottom of slide table 102 is fixed on synchronous belt 105. The specific structure of the belt module body 1 that enables the slide table 102 to reciprocate is not the protected content of this utility model. Only a brief introduction is given. Since the belt module body 1 drives the slide table 102 to reciprocate through synchronous belt 105, it has the advantages of large load-bearing capacity, fast transmission speed, high transmission accuracy and large stroke. See Figure 2 and Figure 3The inner sides of the two end caps 11 of the belt module body 1 are each equipped with a mounting base 12. In this embodiment, there are two adjusting members 2, which are respectively installed on the top of the two mounting bases 12. The position of the adjusting members 2 on the mounting bases 12 can be adjusted along the length of the steel belt 3. For details, please refer to [reference needed]. Figures 2 to 6 The adjusting component 2 has an oblong adjusting hole 21 formed on it. The end of the first adjusting screw 4 passes through the oblong adjusting hole 21 and is screwed onto the top of the mounting base 12. Both adjusting components 2 are mounted on the top of the mounting base 12 by the first adjusting screw 4. The length direction of the oblong adjusting hole 21 is parallel to the length direction of the steel strip 3. The spacing of the oblong adjusting holes 21 in the width direction is slightly larger than the outer diameter of the screw part of the first adjusting screw 4. The spacing of the oblong adjusting holes 21 in the width direction is smaller than the outer diameter of the nut of the first adjusting screw 4. When the first adjusting screw 4 is not tightened, since the oblong adjusting hole 21 for mounting the first adjusting screw 4 is oblong, the adjusting component 2 can move along the length direction of the steel strip 3 on the mounting base 12 when subjected to external force.

[0030] See 4 to Figure 6 In this embodiment, the adjusting member 2 has four oblong adjusting holes 21 and eight first adjusting screws 4. The ends of four first adjusting screws 4 pass through the four oblong adjusting holes 21 on one adjusting member 2 and are screwed onto the top of a mounting base 12. The ends of the other four first adjusting screws 4 pass through the four oblong adjusting holes 21 on another adjusting member 2 and are screwed onto the top of another mounting base 12. The adjusting member 2 can be securely mounted on the mounting base 12 by the four first adjusting screws 4. After the four first adjusting screws 4 on the adjusting member 2 are tightened, the steel strip 3 can maintain a stable tension. In other embodiments, the number of oblong adjusting holes 21 and the number of first adjusting screws 4 on the adjusting member 2 can be adjusted appropriately according to the width of the adjusting member 2 and the steel strip 3.

[0031] See Figures 1 to 3 One end of the steel belt 3 is fixed to an adjusting member 2 on the top of a mounting base 12, and the other end of the steel belt 3 is fixed to an adjusting member 2 on the top of another mounting base 12. Since the position of the adjusting member 2 on the mounting base 12 can be adjusted along the length of the steel belt 3, both adjusting members 2 can simultaneously tighten both ends of the steel belt 3 outwards along its length. Even in long-stroke belt modules, this ensures that the middle section of the steel belt 3 will not sag due to its own weight. For details, please refer to... Figures 2 to 6The adjusting component 2 has a stepped portion 22 formed on it. One end of the steel strip 3 is housed in the stepped portion 22 of one adjusting component 2, and the other end of the steel strip 3 is housed in the stepped portion 22 of another adjusting component 2. The shape of the fixing strip 6 is adapted to the shape of the stepped portion 22. The end of the fixing screw 7 passes through one fixing strip 6 and one end of the steel strip 3 in sequence and is screwed into the stepped portion 22 of one adjusting component 2. The end of the fixing screw 7 passes through another fixing strip 6 and the other end of the steel strip 3 in sequence and is screwed into the stepped portion 22 of another adjusting component 2. The end of the steel strip 3 is installed in the stepped portion 22 of the adjusting component 2 through the fixing strip 6 and the fixing screw 7. The sum of the thickness of the fixing strip 6 and the thickness of the steel strip 3 is equivalent to the longitudinal depth of the stepped portion 22. This ensures that the top of the fixing strip 6 is flush with the top of the adjusting component 2, and the top of the steel strip 3 is lower than the top of the adjusting component 2. This avoids interference between the protruding fixing strip 6 and the top of the steel strip 3 and other components, and also improves the aesthetics of the belt module.

[0032] See Figure 2 and Figure 3 In this embodiment, each fixing bar 6 secures the end of the steel strip 3 to the step portion 22 on the adjusting member 2 with four fixing screws 7, ensuring that the steel strip 3 can be securely fixed in the step portion 22 on the adjusting member 2. In other embodiments, the number of fixing screws 7 can be appropriately adjusted according to the width of the fixing bar 6 and the steel strip 3.

[0033] In other embodiments, depending on the installation requirements and the length of the steel strip 3, the number of adjusting members 2 can also be one. One end of the steel strip 3 is installed in the step portion 22 on the adjusting member 2 by the fixing strip 6 and the fixing screw 7. One end of the steel strip 3 is installed on the top of a mounting base 12 by the adjusting member 2, and the other end of the steel strip 3 is directly fixed on the top of another mounting base 12. The height of the mounting base 12 is slightly higher than the height of the mounting base 12 on which the adjusting member 2 is installed, to ensure that the heights of the two ends of the steel strip 3 are consistent.

[0034] See Figure 2 and Figure 3The end cap 11 has a through hole 111 formed on it. The end of the second adjusting screw 5 passes through the through hole 111 and is screwed into the adjusting member 2. The axis of the through hole 111 is perpendicular to the axis of the oblong adjusting hole 21 on the adjusting member 2. When installing the steel strip 3, first install the two adjusting members 2 on the two mounting seats 12 respectively by the first adjusting screw 4. The first adjusting screw 4 does not need to be tightened first. Then, install the end of the steel strip 3 in the step portion 22 on the adjusting member 2 by the fixing strip 6 and the fixing screw 7. Due to the oblong adjusting hole 21 on the first adjusting screw 4, the steel strip 3 is installed in the step portion 22 on the adjusting member 2. The hole 21 is oblong in shape. During the process of tightening the second adjusting screw 5 on the end cap 11, the adjusting member 2 will move outward along the length of the steel strip 3 to straighten the steel strip 3. When the steel strip 3 is tightened, the first adjusting screw 4 can be tightened. The assembly of the steel strip 3 is very simple, and the middle position of the assembled steel strip 3 will not sag due to its own weight. The axis of the through hole 111 is arranged perpendicular to the axis of the oblong adjusting hole 21 to ensure that during the process of tightening the second adjusting screw 5, the adjusting member 2 will move smoothly outward along the length of the steel strip 3.

[0035] The number of second adjusting screws 5 is at least two. At least one second adjusting screw 5 has its end passing through a hole 111 on one end cap 11 and screwed into an adjusting member 2. At least one second adjusting screw 5 has its end passing through a hole 111 on another end cap 11 and screwed into another adjusting member 2. The two adjusting members 2 can be moved along the length of the steel strip 3 using at least one second adjusting screw 5. In this embodiment, the number of second adjusting screws 5 is six. Each end cap 11 has three holes 111. The ends of three second adjusting screws 5 pass through the three holes 111 on one end cap 11 and screwed into an adjusting member 2. The ends of the other three second adjusting screws 5 pass through the three holes 111 on another end cap 11 and screwed into another adjusting member 2. Each adjusting member 2 can be securely locked to the end cap 11 using three second adjusting screws 5, ensuring that the steel strip 3 maintains a stable tension. In other embodiments, the number of second adjusting screws 5 can be adjusted appropriately according to the width of the adjusting member 2 and the width of the steel strip 3.

[0036] See Figures 1 to 6In this utility model's belt module, when installing the steel belt 3, firstly, the two adjusting members 2 are respectively installed on the two mounting seats 12 inside the two end caps 11 using the first adjusting screw 4. The first adjusting screw 4 does not need to be tightened initially. Then, the two ends of the steel belt 3 are respectively installed in the stepped portions 22 on the two adjusting members 2 using the fixing strip 6 and fixing screw 7. Because the elongated adjusting hole 21 for installing the first adjusting screw 4 is elongated, during the process of tightening the second adjusting screw 5 on the two end caps 11, the adjusting member 2 will move outward along the length of the steel belt 3 to straighten it. The two adjusting members 2 can move simultaneously... Stretch the two ends of the steel belt 3 outwards along its length. When the steel belt 3 is taut, tighten the first adjusting screw 4 on the two adjusting parts 2. The assembly of the steel belt 3 is very simple, and the middle position of the assembled steel belt 3 will not sag due to its own weight. In the belt module with large load and long stroke, the middle position of the steel belt 3 will not sag due to its own weight. The steel belt 3 replaces the upper cover structure in the existing belt straight module, avoiding the problem of the upper cover sag during long stroke, effectively reducing the noise of the slide table 102 during operation, bringing users a quiet user experience, and is suitable for use scenarios where noise is a requirement.

[0037] The above descriptions are merely some embodiments of this utility model, intended to illustrate the technical means of this utility model, and are not intended to limit the technical scope of this utility model. Any obvious improvements made to this utility model by those skilled in the art based on existing common knowledge fall within the protection scope of this utility model.
