Description

Technical Field

[0001] This utility model relates to the field of linear motor module technology, and in particular to a semi-enclosed drive linear motor module. Background Technology

[0002] Linear motor modules have several names, including linear modules, Cartesian coordinate robots, and linear slides. They can achieve linear and curvilinear motion of loads through the combination of individual units, making automation of light loads more flexible and positioning more precise. Some linear motor modules employ a closed design to prevent splashes from falling on their transmission or sliding components, allowing them to be used in harsh industrial environments.

[0003] However, while the enclosed structure effectively isolates external contaminants, its sealing also significantly hinders internal airflow. This causes the linear motor module to generate substantial heat due to friction in its transmission components (such as guide rails and lead screws) and sliding components (such as sliders and bearings) when frequently starting and stopping or under continuous heavy loads. The enclosed environment prevents this heat from dissipating quickly through natural convection, leading to its continuous accumulation inside the module. Prolonged exposure to high temperatures accelerates the aging of the transmission and sliding components. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a semi-enclosed drive linear motor module.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a semi-enclosed drive linear motor module, including a base plate, a fixed platform on the base plate, a first mounting seat and a second mounting seat on both sides of the base plate respectively, two slide rails spaced apart on the fixed platform, a sliding plate slidably mounted on the two slide rails, a first threaded rod rotatably mounted between the first mounting seat and the second mounting seat, the sliding plate being helically connected to the first threaded rod through a threaded hole, a drive motor horizontally mounted on the first mounting seat, the output shaft of the drive motor being connected to the end of the first threaded rod, U-shaped connecting plates with upward openings symmetrically mounted on both sides of the sliding plate, a mounting platform shared at the upper end of the two U-shaped connecting plates, two connecting rods horizontally spaced between the first mounting seat and the second mounting seat, a first U-shaped protective plate and a second U-shaped protective plate detachably mounted on the two connecting rods.

[0006] By adopting the above technical solution, a base plate, a first mounting seat, a second mounting seat, a mounting platform, and a connecting rod are provided. The mounting platform is used to connect to the device that needs to be driven. The drive motor drives the first threaded rod to rotate, which in turn drives the sliding plate to slide, thereby moving the U-shaped connecting plate and the mounting platform. The first U-shaped protective plate and the second U-shaped protective plate shield the sliding plate, the slide rail, and the first threaded rod, preventing flying debris from falling on them and affecting the normal movement of the sliding plate. At the same time, the sliding plate, the slide rail, and the first threaded rod are not completely sealed, and air can still circulate through the space between the fixed platform and the first U-shaped protective plate and the second U-shaped protective plate. This allows the heat on the sliding plate, the slide rail, and the first threaded rod to be naturally and quickly dissipated through air circulation, ensuring their service life and stability.

[0007] Furthermore, the second mounting base is provided with a U-shaped groove, a U-shaped block is slidably disposed in the U-shaped groove, and four compression springs arranged in a rectangular array are disposed in the U-shaped groove.

[0008] By adopting the above technical solution, U-shaped grooves and U-shaped blocks are set. During installation, the first U-shaped protective plate is first placed on the two connecting rods, with one side of it in contact with the first mounting base. Then, the worker picks up the second U-shaped protective plate and tilts it so that one end of it contacts the U-shaped block. Then, the second U-shaped protective plate is moved, causing the U-shaped block to move and the compression spring to be compressed. Next, the second U-shaped protective plate is placed on the connecting rod and released. The compression spring loses its restraint and pushes the U-shaped block and the second U-shaped protective plate to move, so that the second U-shaped protective plate and the first U-shaped protective plate are in close contact, preventing debris from falling onto the first threaded rod and slide rail through the gap between the second U-shaped protective plate and the first U-shaped protective plate.

[0009] Furthermore, two first limiting posts are horizontally spaced apart on the side of the first mounting base adjacent to the second mounting base, and two second limiting posts are also horizontally spaced apart on the side of the first mounting base adjacent to the second mounting base.

[0010] By adopting the above technical solution, a first limiting post and a second limiting post are set to limit the side of the first U-shaped protective plate away from the second U-shaped protective plate, thereby ensuring the stability of the position of the first U-shaped protective plate.

[0011] Furthermore, a fixing block is provided on the side of the second mounting base adjacent to the first mounting base. A threaded hole is vertically opened on the fixing block, and a second threaded rod is spirally arranged in the threaded hole. A handle is provided at the upper end of the second threaded rod, and a pressure block is provided at the lower end.

[0012] By adopting the above technical solution, a fixed block, a second threaded rod, and a handle are set. Rotating the handle drives the second threaded rod to rotate. When the second threaded rod rotates, it moves vertically relative to the fixed block. When the pressure block abuts against the second U-shaped protective plate, the position of the second U-shaped protective plate is fixed.

[0013] Furthermore, the bottom of the U-shaped groove is provided with four fixed tubes arranged in a rectangular array, and a sliding rod is slidably disposed inside the fixed tube, with one end of the sliding rod connected to the U-shaped block.

[0014] Furthermore, the first U-shaped protective plate is provided with two first connecting blocks at intervals on the side adjacent to the second U-shaped protective plate, and the first connecting blocks are provided with protrusions. The second U-shaped protective plate is provided with two second connecting blocks at intervals on the side adjacent to the first U-shaped protective plate, and the second connecting blocks are provided with grooves corresponding to the protrusions.

[0015] By adopting the above technical solution, a first connecting block, a protrusion, a second connecting block, and a groove are set. During installation, the protrusion is located in the groove, so that the first connecting block and the second connecting block are connected, and the first U-shaped protective plate and the second U-shaped protective plate are stably connected.

[0016] Furthermore, the upper end of the U-shaped connecting plate on the side away from the sliding plate is higher than the upper end of the plate on the side adjacent to the sliding plate, and the mounting platform is connected to the plate on the side of the U-shaped connecting plate away from the sliding plate.

[0017] Furthermore, the plates on both sides of the first U-shaped protective plate and the second U-shaped protective plate are located in the inner areas of the two U-shaped connecting plates, and the plate in the middle of the first U-shaped protective plate and the second U-shaped protective plate is located in the area between the sliding plate and the fixed platform.

[0018] Furthermore, the distance between the two connecting rods on opposite sides is the same as the distance between the first U-shaped protective plate and the second U-shaped protective plate relative to their two inner walls.

[0019] In summary, this utility model has the following beneficial effects: In this application, a base plate, a first mounting seat, a second mounting seat, a mounting platform, and a connecting rod are provided. The mounting platform is used to connect to the device that needs to be driven. The drive motor drives the first threaded rod to rotate, which in turn drives the sliding plate to slide, thereby moving the U-shaped connecting plate and the mounting platform. The first U-shaped protective plate and the second U-shaped protective plate shield the sliding plate, the slide rail, and the first threaded rod, preventing flying debris from falling onto them and affecting the normal movement of the sliding plate. Simultaneously, the sliding plate, the slide rail, and the first threaded rod are not completely sealed; air can still circulate through the space between the fixed platform and the first and second U-shaped protective plates, allowing heat on the sliding plate, the slide rail, and the first threaded rod to dissipate naturally and quickly through air circulation, ensuring their service life and stability.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-7As shown in the illustration, this application discloses a semi-enclosed linear motor module, including a base plate 10, a first mounting base 20, a second mounting base 30, a mounting platform 43, and a connecting rod 50. A fixed platform 11 is provided on the base plate 10. The first mounting base 20 and the second mounting base 30 are respectively disposed on both sides of the base plate 10. Two slide rails 12 are spaced apart on the fixed platform 11, and a sliding plate 40 is slidably disposed on both slide rails 12. A first threaded rod 41 is rotatably disposed between the first mounting base 20 and the second mounting base 30. The sliding plate 40 is helically connected to the first threaded rod 41 through a threaded hole. A drive motor 21 is horizontally disposed on the first mounting base 20. The output shaft of the drive motor 21 is connected to the end of the first threaded rod 41, and the drive motor 21 drives the first threaded rod 41 to rotate, thereby driving the sliding plate 40 to slide. U-shaped connecting plates 42 with upward openings are symmetrically disposed on both sides of the sliding plate 40. A mounting platform 43 is commonly disposed on the upper end of the two U-shaped connecting plates 42, and the mounting platform 43 is used to connect to the device to be driven. When the sliding plate 40 slides, it moves the U-shaped connecting plate 42 and the mounting platform 43. Two connecting rods 50 are horizontally spaced between the first mounting base 20 and the second mounting base 30. A first U-shaped protective plate 60 and a second U-shaped protective plate 70 are detachably mounted on both connecting rods 50, with the openings of both the first U-shaped protective plate 60 and the second U-shaped protective plate 70 facing downwards. The first U-shaped protective plate 60 and the second U-shaped protective plate 70 shield the sliding plate 40, the slide rail 12, and the first threaded rod 41, preventing flying debris from falling onto these components and affecting their normal movement. Simultaneously, the sliding plate 40, the slide rail 12, and the first threaded rod 41 are not completely sealed; air can still circulate through the space between the fixed platform 11 and the first U-shaped protective plate 60 and the second U-shaped protective plate 70, allowing heat on these components to dissipate naturally and quickly, ensuring their service life and stability.

[0030] Specifically, the upper end of the U-shaped connecting plate 42 on the side away from the sliding plate 40 is higher than the upper end of the side adjacent to the sliding plate 40. The mounting platform 43 is connected to the side of the U-shaped connecting plate 42 away from the sliding plate 40, ensuring that there is space between the mounting platform 43 and the sliding plate 40. The plates on both sides of the first U-shaped protective plate 60 and the second U-shaped protective plate 70 are located in the inner areas of the two U-shaped connecting plates 42, and the middle plate of the first U-shaped protective plate 60 and the second U-shaped protective plate 70 is located in the area between the sliding plate 40 and the fixed platform 11. The distance between the two connecting rods 50 on the side away from each other is the same as the distance between the two inner walls of the first U-shaped protective plate 60 and the second U-shaped protective plate 70. When the first U-shaped protective plate 60 and the second U-shaped protective plate 70 are located on the two connecting rods 50, the inner top wall of the first U-shaped protective plate 60 and the second U-shaped protective plate 70 are in contact with the two connecting rods 50, and the two inner walls are also in contact with the two connecting rods 50.

[0031] During setup, a U-shaped groove 31 is provided on the second mounting base 30, and a U-shaped block 32 is slidably disposed within the U-shaped groove 31. Four compression springs 33 arranged in a rectangular array are disposed within the U-shaped groove 31, with one end of the compression spring 33 connected to the bottom of the U-shaped groove 31 and the other end connected to the U-shaped block 32. During installation, the first U-shaped protective plate 60 is first placed on the two connecting rods 50, with one side of it in contact with the first mounting base 20. Then, the operator picks up the second U-shaped protective plate 70 and tilts it so that one end of it contacts the U-shaped block 32. The second U-shaped protective plate 70 is then moved, causing the U-shaped block 32 to move and the compression spring 33 to be compressed. Next, the second U-shaped protective plate 70 is placed on the connecting rod 50 and released. Then, the first U-shaped protective plate 60 and the second U-shaped protective plate 70 are pressed appropriately to ensure that the inner top surfaces of the first U-shaped protective plate 60 and the second U-shaped protective plate 70 are in contact with the connecting rod 50, thereby ensuring that the first U-shaped protective plate 60 and the second U-shaped protective plate 70 are aligned. The compression spring 33, no longer restrained, pushes the U-shaped block 32 and the second U-shaped protective plate 70 to move, causing the second U-shaped protective plate 70 to come into close contact with the first U-shaped protective plate 60, preventing debris from falling onto the first threaded rod 41 and the slide rail 12 through the gap between the second U-shaped protective plate 70 and the first U-shaped protective plate 60. Four fixed tubes 38 arranged in a rectangular array are provided at the bottom of the U-shaped groove 31. A sliding rod 39 is slidably installed inside each fixed tube 38, with one end of the sliding rod 39 connected to the U-shaped block 32 to ensure the stability of the sliding of the U-shaped block 32.

[0032] In the specific configuration, two first limiting posts 22 are horizontally spaced on the side of the first mounting base 20 adjacent to the second mounting base 30, and two second limiting posts 23 are also horizontally spaced on the side of the first mounting base 20 adjacent to the second mounting base 30. The distance between the adjacent sides of the two first limiting posts 22 is consistent with the distance between the two outer walls of the first U-shaped protective plate 60 and the second U-shaped protective plate 70. Two second limiting posts 23 are also spaced on the side of the first mounting base 20 adjacent to the second mounting base 30. The distance between the lower side of the second limiting post 23 and the upper side of the connecting rod 50 is consistent with the thickness of the middle part of the first U-shaped protective plate 60. When the first U-shaped protective plate 60 is located on the connecting rod 50, both the first limiting posts 22 and the second limiting posts 23 are in contact with the outer wall of the first U-shaped protective plate 60, limiting the side of the first U-shaped protective plate 60 away from the second U-shaped protective plate 70, thus ensuring the stability of the position of the first U-shaped protective plate 60. A fixing block 34 is provided on the side of the second mounting base 30 adjacent to the first mounting base 20. A threaded hole is vertically opened on the fixing block 34, and a second threaded rod 35 is spirally arranged in the threaded hole. A handle 36 is provided at the upper end of the second threaded rod 35 and a pressure block 37 is provided at the lower end. Rotating the handle 36 drives the second threaded rod to rotate. When the second threaded rod 35 rotates, it moves vertically relative to the fixing block 34. When the pressure block 37 abuts against the second U-shaped protective plate 70, the position of the second U-shaped protective plate 70 is fixed.

[0033] Two first connecting blocks 61 are spaced apart on the side of the first U-shaped protective plate 60 adjacent to the second U-shaped protective plate 70. Each first connecting block 61 has a protrusion 62. Two second connecting blocks 71 are spaced apart on the side of the second U-shaped protective plate 70 adjacent to the first U-shaped protective plate 60. Each second connecting block 71 has a groove 72 corresponding to the protrusion 62. During installation, the protrusion 62 is located in the groove 72, so that the first connecting block 61 and the second connecting block 71 are connected, and the first U-shaped protective plate 60 and the second U-shaped protective plate 70 are stably connected.

[0034] The operating principle of a semi-enclosed linear motor module in this embodiment is as follows:

[0035] When installing the first U-shaped protective plate 60 and the second U-shaped protective plate 70, first start the drive motor 21 to drive the sliding plate 40, U-shaped connecting plate 42, and mounting platform 43 to move to a position near the second mounting base 30. Then, the worker places the first U-shaped protective plate 60 on the two connecting rods 50, with one side of it contacting the first mounting base 20, and the first limiting post 22 and the second limiting post 23 both contacting the outer wall of the first U-shaped protective plate 60. Then, the drive motor 21 drives the sliding plate 40, U-shaped connecting plate 42, and mounting platform 43 to move to a position near the first mounting base 20. Then, the worker picks up the second U-shaped protective plate 70 and tilts it so that one end contacts the U-shaped block 32. Then, the worker moves the second U-shaped protective plate 70, causing the U-shaped block 32 to move and the compression spring 33 to be compressed. Then, the worker places the second U-shaped protective plate 70 on the connecting rod 50 and releases it. The compression spring 33 loses its restraint and pushes the U-shaped block 32 and the second U-shaped protective plate 70 to move, and the protrusion 62 is engaged in the groove 72. Next, the operator turns handle 36 to rotate the second thread, causing pressure block 37 to contact the second U-shaped protective plate 70, thus fixing the position of the second U-shaped protective plate 70. Air can circulate through the space between the fixed platform 11 and the first U-shaped protective plate 60 and the second U-shaped protective plate 70, allowing the heat on the sliding plate 40, slide rail 12, and first threaded rod 41 to dissipate naturally and quickly through air circulation, ensuring their service life and stability.

[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
