[0054] like Figures 1 to 9 As shown, this embodiment provides a linear module that can improve the appearance of the linear module, facilitate the miniaturization of the linear module, and reduce the operating noise of the linear module. The linear module includes a profile housing 1, a first guide shaft 2, a second guide shaft 3, a movable base 4, and a drive assembly 5.
[0055] Among them, see Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A receiving cavity 11 is formed in the profile shell 1, and the first guide shaft 2 and the second guide shaft 3 extend along the first direction, and the first guide shaft 2 and the second guide shaft 3 are arranged in the receiving cavity 11 at intervals along the second direction, and the first direction is perpendicular to the second direction. The movable seat 4 is movably arranged in the profile shell 1 along the first direction, and is at least partially located in the receiving cavity 11. The portion of the movable seat 4 located in the receiving cavity 11 is provided with a first rolling body 401 and a second rolling body 402 between the first guide shaft 2 and the second guide shaft 3. The first rolling body 401 rolls with the first guide shaft 2, and the second rolling body 402 rolls with the second guide shaft 3, and the installation position of the second rolling body 402 in the second direction is adjustable; the portion of the movable seat 4 located outside the receiving cavity 11 is configured to install the component to be moved. The driving assembly 5 includes a synchronous belt (not shown) that is rotatably arranged in the receiving cavity 11 along the first direction. The synchronous belt is fixedly connected to the movable seat 4 and is used to drive the movable seat 4 to move along the first direction.
[0056] In the linear module provided by this embodiment, during the synchronous belt transmission process, the synchronous belt drives the movable seat 4 to move along the first direction. At the same time, the first rolling body 401 rolls with the first guide shaft 2, and the second rolling body 402 rolls with the second guide shaft 3, ensuring that the movable seat 4 always moves along the first direction, thereby causing the part to be moved to move in the first direction, and realizing that the linear module drives the part to be moved to move linearly. Since the first guide shaft 2, the second guide shaft 3, the first rolling body 401, the second rolling body 402 and the synchronous belt are all located in the accommodating cavity 11 of the profile shell 1, and the first rolling body 401 and the second rolling body 402 are located between the first guide shaft 2 and the second guide shaft 3, that is, all the moving parts are located in the accommodating cavity 11, the exterior of the entire linear module is neat and beautiful, and is conducive to the miniaturized design of the linear module; at the same time, arranging all the moving parts in the accommodating cavity 11 can reduce the noise generated during the operation of the linear module. Since the installation position of the second rolling body 402 in the second direction is adjustable, when assembling the first rolling body 401 and the first guide shaft 2 and the second rolling body 402 and the second guide shaft 3, the distance between the second rolling body 402 and the first rolling body 401 can be adjusted by adjusting the installation position of the second rolling body 402, which makes it easier to fit the first rolling body 401 and the first guide shaft 2 and the second rolling body 402 and the second guide shaft 3, thereby improving assembly efficiency.
[0057] like Figure 1 、 Figure 2 and Figure 3 As shown, in this embodiment, the X direction is the first direction, and the Z direction is the second direction. The moving component can be any component that requires linear movement. For example, in a printing device, the moving component can be a laser head. In production line equipment, the moving component can also be a gripper that grasps parts.
[0058] See Figure 3 、 Figure 4 and Figure 6 The movable seat 4 is provided with a clamping member 403, and the synchronous belt is fixedly connected to the movable seat 4 through the clamping member 403. When the synchronous belt is driven, the synchronous belt can drive the movable seat 4 to move relative to the profile shell 1 along the first direction, thereby driving the movable component to move linearly along the first direction.
[0059] In this embodiment, the clamping member 403 includes two belt clamps, which respectively clamp and fix the two ends of the synchronous belt. Further, the belt clamps have through-holes 4031, and the ends of the synchronous belt pass through the corresponding through-holes 4031 to pass through the belt clamps.
[0060] Optionally, see Figure 2 、 Figure 3 and Figure 4The movable seat 4 includes a first mounting plate 41 and a second mounting plate 42 that are spaced apart. The first mounting plate 41 is located in the accommodating cavity 11. The first rolling body 401 and the second rolling body 402 are both arranged on the first mounting plate 41. The second mounting plate 42 is located on the outside of the profile shell 1 and is used to install the components to be moved. The first mounting plate 41 provides a mounting base for the first rolling body 401 and the second rolling body 402, which facilitates hiding the first rolling body 401 and the second rolling body 402 in the accommodating cavity 11 of the profile shell 1, ensuring the neat appearance of the linear module. The second mounting plate 42 provides a mounting base for the components to be moved, which facilitates the disassembly and assembly of components that need to move linearly. The first mounting plate 41 and the second mounting plate 42 are spaced apart, which can reserve enough space for the movable seat 4 to move as a whole relative to the profile shell 1, avoiding interference between the first mounting plate 41 and the second mounting plate 42 and the profile shell 1.
[0061] See Figure 2 、 Figure 3 and Figure 5 The profile housing 1 is provided with a slideway 12 extending in a first direction and communicating with the accommodating cavity 11. The first mounting plate 41 and the second mounting plate 42 are connected by a slider 411. The slider 411 is located within the slideway 12 and slides with the slideway 12. When the synchronous belt is driven, the synchronous belt drives the first mounting plate 41 and the second mounting plate 42 to move in the first direction. During this process, the slider 411 slides within the slideway 12, enabling the second mounting plate 42 to drive the moving component to move in the first direction. The arrangement of the slider 411 and the slideway 12 can limit the movement of the movable seat 4 as a whole to always move in the first direction, ensuring the movement accuracy of the movable seat 4 and improving the smoothness of the movement of the movable seat 4.
[0062] Exemplarily, the slider 411 is a convex strip structure protruding from the first mounting plate 41. A groove is recessed on the second mounting plate 42 at a position corresponding to the convex strip structure. The convex strip structure partially snaps into the groove. The first mounting plate 41 has a first connecting hole on the convex strip structure, and the second mounting plate 42 has a second connecting hole at the position of the groove. Bolts or screws, or other fixing members, are passed through the first and second connecting holes to secure the first and second mounting plates 41 and 42 together, facilitating assembly and disassembly of the movable seat 4 and the profile housing 1. In other embodiments, the slider 411 can also be provided on the second mounting plate 42.
[0063] Optionally, see Figure 4 、 Figure 5 and Figure 6The first mounting plate 41 is provided with an adjustment plate 43 whose mounting position is adjustable along the second direction, and the second rolling body 402 is rotatably provided on the adjustment plate 43. Since the first rolling body 401 and the second rolling body 402 need to be assembled between the first guide shaft 2 and the second guide shaft 3, the adjustment plate 43 with adjustable mounting position is provided. When assembling the first rolling body 401 and the second rolling body 402 with the first guide shaft 2 and the second guide shaft 3, the first rolling body 401 can be first engaged with the first guide shaft 2, and then the adjustment plate 43 can be moved along the second direction to make the second rolling body 402 approach the first rolling body 401 along the second direction. Finally, the adjustment plate 43 can be moved along the second direction again to make the second rolling body 402 engage with the second guide shaft 3. This makes it easier for the second rolling body 402 to enter between the first guide shaft 2 and the second guide shaft 3, thereby reducing assembly difficulty and improving assembly efficiency.
[0064] In this embodiment, two first rolling bodies 401 are arranged at intervals in the first direction, and one second rolling body 402 is provided. The second rolling body 402 is located between the two first rolling bodies 401. The two first rolling bodies 401 and one second rolling body 402 form a triangular force-bearing structure, which has more stable force and can improve the movement stability of the movable seat 4 in the first direction.
[0065] Exemplarily, the first rolling body 401 and the second rolling body 402 are both rollers, and a rolling groove is provided on the roller along the circumference. The first guide shaft 2 can be clamped in the rolling groove of the first rolling body 401, and the second guide shaft 3 can be clamped in the rolling groove of the second rolling body 402, ensuring that the first rolling body 401 and the first guide shaft 2, and the second rolling body 402 and the second guide shaft 3 are stably matched.
[0066] See Figure 5 、 Figure 6 and Figure 7 The first mounting plate 41 is provided with a movable groove 412, and the adjustment plate 43 is located in the movable groove 412. A first elastic member 44 extending along the second direction is provided between the adjustment plate 43 and the groove wall of the movable groove 412. Under the elastic force of the first elastic member 44, the adjustment plate 43 has a tendency to drive the second rolling element 402 to abut against the second guide shaft 3 along the second direction. Specifically, when the adjustment plate 43 is driven to approach the first rolling element 401 along the second direction, the adjustment plate 43 squeezes the first elastic member 44. The first elastic member 44 accumulates elastic potential energy, causing the adjustment plate 43 to have a tendency to move away from the first rolling element 401. After the second rolling element 402 is adjusted between the first guide shaft 2 and the second guide shaft 3, the adjustment plate 43 is released. The adjustment plate 43 can then be moved in a direction away from the first rolling element 401 under the elastic force of the first elastic member 44, thereby causing the second rolling element 402 to move to engage with the second guide shaft 3 and remain in the state of engaging with the second guide shaft 3.
[0067] See Figure 5 and Figure 7 The adjustment plate 43 is provided with a first limiting hole 434 extending in the second direction, and the wall of the movable slot 412 is provided with a second limiting hole 414 extending in the second direction. One end of the first elastic member 44 is limited by the first limiting hole 434, and the other end is limited by the second limiting hole 414. This ensures that the first elastic member 44 can always extend and retract in the second direction, thereby stabilizing the force applied to the adjustment plate 43. For example, the first elastic member 44 is a spring.
[0068] Optionally, see Figure 5 、 Figure 6 and Figure 7 The outer edge of the adjustment plate 43 is provided with a circumferentially recessed retaining groove 431. The edge of the movable groove 412 engages within the retaining groove 431, and the retaining groove 431 and the edge of the movable groove 412 are capable of sliding engagement in the second direction. That is, when adjusting the position of the adjustment plate 43, the retaining groove 431 and the edge of the movable groove 412 slide in engagement. The provision of the retaining groove 431 restricts the movement of the adjustment plate 43 to the second direction, preventing the adjustment plate 43 from shifting, and ensuring that the second rolling element 402 accurately engages the second guide shaft 3 in the second direction.
[0069] See Figure 5 and Figure 6 The movable groove 412 has an opening, and the first mounting plate 41 is detachably provided with a fixing plate 45 at the opening. The fixing plate 45 is provided with a guide column 451 extending along the second direction, and the adjustment plate 43 is provided with a guide hole 432 extending along the second direction (such as Figure 7 As shown in FIG, the guide post 451 is inserted into the guide hole 432 and can slide with the guide hole 432. The guide post 451 cooperates with the guide hole 432 to further limit the movement direction of the adjustment plate 43 in the second direction, and to prevent the adjustment plate 43 from sliding in the second direction. Figure 3 The Y direction of the adjusting plate 43 is moved to ensure the installation stability of the adjusting plate 43. The setting of the fixing plate 45 allows the adjusting plate 43 to be disassembled from the opening of the movable groove 412, which is convenient for assembly and later maintenance.
[0070] Exemplarily, the fixing plate 45 is fastened to the bottom end of the first mounting plate 41 by screws, which is convenient for assembly and disassembly.
[0071] See Figure 5 and Figure 6The adjustment plate 43 is provided with a fixing portion 433 protruding along the second direction. The first mounting plate 41 is detachably provided with a first fastener. The first fastener is capable of fastening the fixing portion 433 to the first mounting plate 41 to fix the position of the adjustment plate 43 in the second direction. After the adjustment plate 43 is adjusted to the point where the second rolling element 402 engages with the second guide shaft 3, the fixing portion 433 is fixed to the first mounting plate 41 using the first fastener, preventing the adjustment plate 43 from moving relative to the first mounting plate 41. This ensures that the second rolling element 402 remains engaged with the second guide shaft 3 and does not become disengaged from the second guide shaft 3.
[0072] like Figure 4 and Figure 6 As shown, the fixing portion 433 is provided with a third limiting hole 4331, and the first mounting plate 41 is provided with a fixing hole 413. The first fastener can pass through the third limiting hole 4331 and be fastened in the fixing hole 413 to limit the position of the adjustment plate 43 in the second direction. Exemplarily, the first fastener is a bolt, and the fixing hole 413 is a threaded hole. The adjustment plate 43 can be fixed by tightening the bolt in the threaded hole.
[0073] See Figure 1 、 Figure 2 and Figure 3 The accommodating chamber 11 includes a first chamber 111 and a second chamber 112 that are connected to each other. The first guide shaft 2 and the second guide shaft 3 are arranged in the first chamber 111 at intervals along the second direction. The driving assembly 5 also includes a driving member 51, a driving pulley 52 and a driven pulley 53. The housing of the driving member 51 is located in the accommodating chamber 11. The driving pulley 52 is arranged at the output end of the driving member 51 and is located in the second chamber 112. The driven pulley 53 is rotatably arranged in the second chamber 112. The synchronous belt is wound around the driving pulley 52 and the driven pulley 53. When the driving member 51 drives the driving pulley 52 to rotate, the driving pulley 52 drives the synchronous belt and the driven pulley 53 to rotate, realizing synchronous belt transmission, and then the synchronous belt drives the movable seat 4 to move along the first direction.
[0074] In this embodiment, Figure 3 As shown, the first chamber 111 and the second chamber 112 are arranged side by side in the third direction. Figure 3 Such an arrangement can prevent the movement of the synchronous belt and the first rolling element 401, the second rolling element 402 and the first mounting plate 41 from interfering with each other, thereby ensuring movement stability and rationally arranging the various moving parts within the accommodating cavity 11.
[0075] See Figure 2 and Figure 8The profile shell 1 is provided with a card slot 14 on the upper and lower opposite inner walls of the first chamber 111. The first guide shaft 2 and the second guide shaft 3 are clamped in the corresponding card slot 14, and the first guide shaft 2 and the second guide shaft 3 protrude from the card slot 14, ensuring that the first rolling body 401 can roll with the first guide shaft 2, and the second rolling body 402 can roll with the second guide shaft 3.
[0076] Optionally, see Figure 2 、 Figure 3 、 Figure 8 and Figure 9 The profile housing 1 is provided with a tensioning mechanism 6, which includes a fixed block 61, an adjusting block 62, and a second elastic member 63. The fixed block 61 is fixedly mounted on the profile housing 1 and located within the second chamber 112. The adjusting block 62 is adjustable along a first direction within the profile housing 1 and located within the second chamber 112. The driven pulley 53 is rotatably mounted on the adjusting block 62. The second elastic member 63 is constrained between the fixed block 61 and the adjusting block 62. Under the elastic force of the second elastic member 63, the adjusting block 62 always tends to move away from the fixed block 61, thereby causing the driven pulley 53 to tension the timing belt.
[0077] When assembling the synchronous belt, you can first move the adjusting block 62 in the direction close to the fixed block 61 to make the driven pulley 53 close to the driving pulley 52, so that the synchronous belt is wound around the driven pulley 53. During this process, the second elastic member 63 is compressed to accumulate elastic potential energy. When the adjusting block 62 is released, the adjusting block 62 moves in the direction away from the fixed block 61 under the elastic force of the second elastic member 63, so that the synchronous belt is pre-tensioned, which can prevent the synchronous belt from detaching from the driven pulley 53 and improve the assembly efficiency of the synchronous belt.
[0078] See Figure 9 The adjusting block 62 is provided with a protruding column 621 extending in the first direction. One end of the second elastic member 63 is fixedly connected to the fixing block 61, and the other end is sleeved on the protruding column 621. The protruding column 621 can limit the expansion and contraction direction of the second elastic member 63, ensuring the stable expansion and contraction of the second elastic member 63. The second elastic member 63 is exemplarily a spring.
[0079] Exemplarily, the driving member 51 is a motor, the housing of the motor is located in the accommodating cavity 11 of the profile housing 1 , and the driving pulley 52 is fixed to the output shaft of the motor.
[0080] See Figure 8The profile housing 1 is provided with an adjustment hole 13 extending along a first direction. An adjustable second fastener 64 is disposed within the adjustment hole 13.
