Description

Technical Field

[0001] The utility model relates to the field of linear motors, in particular to a fully enclosed dust-free linear motor module. Background Art

[0002] The linear motor module has a series of advantages such as fast single-body movement speed, high repeat positioning accuracy, and long service life. Its application greatly improves production efficiency. A steel belt type fully enclosed linear motor module is disclosed in the Chinese utility model patent with announcement number CN 220775617U. A first chamber is formed by covering the base and the upper ends of the first end plate and the second end plate with a soft steel plate, and a limit switch is arranged in the first chamber. The limit switch is connected to the outside of the first chamber through a wire and a second socket. The second socket is an aviation socket with dustproof function. This design places the limit switch and the induction sheet in an internal dust-free environment without affecting the appearance and function of the equipment, thereby avoiding dust accumulation.

[0003] In order to ensure the accuracy of the slide and avoid wear during movement, the second socket does not contact the upper surface of the base, that is, there is a certain gap between the two, and the soft steel plate will bulge above the slide, leaving a gap between the soft steel plate and the opening of the base (as shown in Figure 6). The two overlap each other so that external dust can enter the base through these gaps, which will affect the internal components. To this end, we designed a fully enclosed dust-free linear motor module. Utility Model Content

[0004] In order to solve the technical problem that the second socket does not contact the upper surface of the base and there is a certain gap between the two, the utility model provides a fully enclosed dust-free linear motor module.

[0005] The utility model is implemented by the following technical scheme: a fully enclosed dust-free linear motor module, including a base, a slide body is arranged inside the base for sliding left and right movement, and a connecting slide is arranged above the slide body, and moving frames are respectively installed at the front and rear ends of the connecting slide, and support rollers and pressing rollers are respectively rotatably arranged at the left and right ends of the front and rear sides of the two moving frames, a soft belt is arranged at the opening above the base, and the soft belt passes through the two support rollers and pressing rollers on the left and right sides in sequence, sealing belts are arranged on the front and rear sides of the upper end surface of the base, and the sealing belts are designed to be perpendicular to the base, and a plurality of contact components distributed at equal intervals are installed on the outward surfaces of the front and rear two moving frames, and the sealing belt is placed between the contact component and the moving frame, and the sealing belt is in contact with the outer surface of the moving frame.

[0006] As a further improvement of the above scheme, the contact assembly includes a mounting bracket, a plurality of the mounting brackets are mounted on the outer surface of the movable frame by screws, and a pressure roller is rotatably installed inside the mounting bracket by an axle pin, the outer diameter of the pressure roller is larger than the width inside the mounting bracket, and there is a spacing between the pressure roller and the movable frame, and the spacing is no larger than the thickness of the sealing belt, and the slide body will cause the two movable frames to move synchronously during the movement, thereby causing the contact assembly installed on the outer side of the movable frame to move together, and during the movement of the contact assembly, the pressure roller will cause part of the sealing belt to deform and fit against the outer surface of the movable frame, thereby being able to seal the gap between the movable frame and the base, so that external dust cannot enter the base through the gap between the two.

[0007] As a further improvement of the above scheme, the sealing belt is arranged in an L-shaped structure, and fixed plates are arranged on the left and right sides of the base, the left and right ends of the sealing belt are respectively fixed on the two fixed plates, and the bottom end of the sealing belt is fixed above the base, the lower half of the sealing belt is fixed above the base by screws, and the left and right ends are fixed on the two fixed plates, which makes the entire sealing belt have an L-shaped structure, and there will be no gap between the sealing belt and the base, thereby ensuring the sealing performance.

[0008] As a further improvement of the above scheme, the movable frame is not in direct contact with the surface of the base, and there is a gap between the two. The height of the gap is greater than the thickness of the sealing belt, and the bent portion of the sealing belt is below the movable frame. The lower half of the sealing belt is placed below the movable frame and does not contact it, which improves the sealing performance without causing friction obstruction thereto.

[0009] As a further improvement of the above scheme, a push plate is installed between the left and right sides of the two moving frames by screws, the lower half of the push plate is designed to be inclined outward, and the bottom end of the push plate is in sliding contact with the upper surface of the soft belt. When the push plate moves with the moving frame, it can clean up the dust attached to the soft belt so that it will not remain on the soft belt, and then fall into the inside of the base when the soft belt is raised.

[0010] As a further improvement of the above solution, an upper cover plate is arranged above the two movable frames, and the left and right sides of the upper cover plate are in contact with the upper surfaces of the two pushing plates, which can shield the upper part of the movable plate and improve the sealing performance.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model arranges a plurality of contact components on the front and rear sides of the mobile frame, and cooperates with the sealing belt arranged on the base. The pressing roller in the contact component can make the sealing belt deform and fit on the outer surface of the mobile frame, thereby sealing the gap between the mobile frame and the base, so that the external dust cannot enter the base through the gap between the two.

[0013] 2. By arranging push plates on the left and right sides of the mobile frame, the lower part of the push plates is tilted outward and in sliding contact with the upper surface of the soft belt, which can clean up the dust attached to the soft belt so that it will not remain on the soft belt, and prevent the dust from falling into the base when the soft belt is raised.

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0022] Example:

[0023] Please combine Figure 1-Figure 4A fully enclosed dust-free linear motor module of the present embodiment includes a base 1, a slide body 9 is slidably arranged inside the base 1, and a connecting slide 8 is arranged above the slide body 9, and a moving frame 7 is respectively installed at the front and rear ends of the connecting slide 8, and support rollers 71 and pressing rollers 72 are rotatably arranged at the left and right ends of the front and rear sides of the two moving frames 7, respectively, and a soft belt 2 is arranged at the opening above the base 1, and the soft belt 2 passes through the two support rollers 71 and the pressing roller 72 on the left and right sides in sequence, and sealing belts 4 are arranged on the front and rear sides of the upper end surface of the base 1, and the sealing belt 4 is designed to be perpendicular to the base 1, and a plurality of contact components 5 distributed at equal intervals are installed on the outward side surfaces of the front and rear moving frames 7, and the sealing belt 4 is placed between the contact component 5 and the moving frame 7, and the sealing belt 4 is in contact with the outer surface of the moving frame 7.

[0024] The contact assembly 5 includes a mounting bracket 51, and multiple mounting brackets 51 are installed on the outer surface of the movable frame 7 by screws, and a pressure roller 52 is rotatably installed inside the mounting bracket 51 by an axle pin. The outer diameter of the pressure roller 52 is larger than the width inside the mounting bracket 51, and there is a spacing between the pressure roller 52 and the movable frame 7, which is no larger than the thickness of the sealing belt 4. During the movement of the slide body 9, the two movable frames 7 will move synchronously, thereby causing the contact assembly 5 installed on the outer side of the movable frame 7 to move together. During the movement of the contact assembly 5, the pressure roller 52 will cause part of the sealing belt 4 to deform and fit onto the outer surface of the movable frame 7, thereby being able to seal the gap between the movable frame 7 and the base 1, so that external dust cannot enter the base 1 through the gap between the two.

[0025] The sealing belt 4 is arranged in an L-shaped structure, and a fixing plate 41 is arranged on the left and right sides of the base 1. The left and right ends of the sealing belt 4 are respectively fixed on the two fixing plates 41, and the bottom end of the sealing belt 4 is fixed on the top of the base 1. The lower half of the sealing belt 4 is fixed on the top of the base 1 by screws, and the left and right ends are fixed on the two fixing plates 41. This makes the entire sealing belt 4 have an L-shaped structure, and there will be no gap between the sealing belt 4 and the base 1, thereby ensuring the sealing performance.

[0026] The movable frame 7 is not in direct contact with the surface of the base 1, and there is a gap between the two. The height of the gap is greater than the thickness of the sealing belt 4, and the bent portion of the sealing belt 4 is below the movable frame 7. The lower half of the sealing belt 4 is placed below the movable frame 7 and does not contact it, which improves the sealing performance without causing frictional obstruction thereto.

[0027] A push plate 6 is installed between the left and right sides of the two moving frames 7 by screws. The lower half of the push plate 6 is designed to be inclined outward, and the bottom end of the push plate 6 is in sliding contact with the upper surface of the soft belt 2. When the push plate 6 moves with the moving frame 7, it can clean up the dust attached to the soft belt 2 so that it will not remain on the soft belt 2, and then fall into the inside of the base 1 when the soft belt 2 is raised.

[0028] An upper cover plate 3 is arranged above the two moving frames 7. The left and right sides of the upper cover plate 3 are in contact with the upper surfaces of the two pushing plates 6, which can shield the upper part of the moving plate and improve the sealing performance.

[0029] The implementation principle of a fully enclosed dust-free linear motor module in the embodiment of the present application is as follows: in actual use, the connecting slide 8 fixed on the slide body 9 can enable the two moving frames 7 to move synchronously, so that the clamping rollers 52 in the multiple contact components 5 on the front and rear sides can cause the sealing belt 4 to deform and fit onto the outer surface of the moving frame 7, thereby sealing the gap between the moving frame 7 and the base 1, so that external dust cannot enter the base 1 through the gap between the two, and the push plates 6 arranged on the front and rear sides of the moving frame 7 will also move accordingly, which can clean up the dust attached to the soft belt 2 so that it will not remain on the soft belt 2, and then fall into the base 1 when the soft belt 2 is raised.

[0030] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
