[0035] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0036] In view of the defects of low precision and poor dust prevention of linear slides in the prior art, the present application proposes a fully enclosed slide directly driven by a rod-shaped motor, which has the advantages of high precision and good dust prevention, and can meet the requirements for the use of linear slides in high-end manufacturing fields such as wafer semiconductors.

[0037] Combination Figure 1-3 As shown, the fully enclosed slide includes a box-type base 1 with an open side at the top, a rod-shaped motor, a stage 3 and a flexible steel belt 4 for sealing the open side; the rod-shaped motor is built into the base 1, and the two ends of the motor stator 21 of the rod-shaped motor are respectively fixed between the end plates 11 at the two ends of the base 1, and the motor mover 22 is slidably connected to the bottom plate 12 of the base 1; the stage 3 is located above the open side, and the stage 3 is fixedly connected to the motor mover 22 of the rod-shaped motor, and the motor mover 22 drives the stage 3 to slide linearly relative to the base 1; the two ends of the flexible steel belt 4 are fixed to the base 1, and the flexible steel belt 4 is pressed on the stage 3 to keep the open side of the base 1 sealed during the sliding process of the stage 3, so as to prevent the dust generated in the base 1 from overflowing through the open side and polluting the external processing environment where the fully enclosed slide is located.

[0038] The rod-shaped motor has a linear rod-shaped overall shape, and is a type of linear motor, including a motor stator 21 and a motor mover 22 coaxially connected to the motor stator 21. The motor mover 22 can move axially along the motor stator 21, thereby driving the stage 3 to move linearly. The workpiece to be tested or processed is fixed to the portion of the stage 3 where the flexible steel belt 4 is exposed, thereby realizing the use of a fully enclosed slide to drive the workpiece to move linearly as required to meet the actual needs of production and processing.

[0039] Specifically, the loading platform 3 includes a support platform 31 for providing guidance and support for the flexible steel belt 4 and a pressure strip 33 for pressing the flexible steel belt 4. The pressure strips 33 are arranged at intervals at both ends of the support platform 31, so the number of the pressure strips 33 is at least 2. The flexible steel belt 4 passes through the bottom of the pressure strip 33 and is pressed on the support platform 31. The pressure strip 33 can reduce the gap between the flexible steel belt 4 at both ends of the support platform 31 and the opening side.

[0040] In addition, guide slopes 32 are respectively provided on both end sides of the support platform 31 , and the guide slopes 32 can also enable the flexible steel belt 4 to maintain a better fitting relationship with the upper surface of the support platform 31 .

[0041] A guide member is provided on the lower side of the pressure strip 33 and / or the upper side of the support platform 31 to reduce the sliding friction between the flexible steel belt 4 and the loading platform 3, thereby bringing at least the following technical effects:

[0042] 1. Since the slide guide reduces the sliding friction between the flexible steel belt 4 and the loading platform 3, the friction generated by the flexible steel belt 4 on the loading platform 3 is smaller, which is beneficial to improving the sliding accuracy of the loading platform 3.

[0043] 2. The sliding friction between the flexible steel belt 4 and the loading platform 3 is small, which can reduce the wear of each to extend the service life, and can also reduce the dust generated by friction by reducing the sliding friction between the two.

[0044] The guide member is a roller and / or a roller, which is arranged on the lower side of the pressure strip 33 and / or the guide inclined surface 32 .

[0045] Further integration Figure 5 As shown, in this embodiment, the pressure strip 33 is integrally formed as a roller 332 .

[0046] Further integration Figure 6 As shown, in this embodiment, three ball holes are arranged at intervals on each of the pressure strips 33, and balls 332 are respectively arranged in the three ball holes.

[0047] Of course, in Figure 5 and Figure 6 Based on the illustrated example, rollers or balls may be provided on the guide slope 32 as required.

[0048] Recombination Figure 5 and Figure 6 As shown, a groove 34 is provided at the junction of the two guide inclined surfaces 32, and the guide slide is provided in the groove 34. The guide slide is a roller, a roller or / and a guide slide made of a wear-resistant material, for example Figure 5 The guide member in the middle groove 34 is a roller 332. Figure 6 The guide ball 332 is in the middle groove 34 .

[0049] Further integration Figure 1-Figure 4 As shown, the two ends of the flexible steel belt 4 are respectively pressed and fixed to the end plates 11 at the two ends of the base 1 through a pressing plate 5. Specifically, the end plate 11 is provided with a plurality of first fixing holes 111; the end of the flexible steel belt 4 is provided with a plurality of second fixing holes 41, and the aperture of the second fixing holes 41 in the length direction of the flexible steel belt 4 is larger than the first fixing holes 111; the pressing plate 5 is correspondingly provided with a plurality of fixing members 51, and the fixing members 51 pass through the second fixing holes 41 and are fixed to the first fixing holes 111 to press and fix the end of the flexible steel belt 4 between the pressing plate 5 and the end plate 11.

[0050] When fixing the flexible steel belt 4, one end thereof is fixed by a pressing plate 5, and the other end can be fixed by another pressing plate 5 after adjusting the tightness of the flexible steel belt 4 to ensure that the flexible steel belt 4 can maintain a good sealing fit with the opening side of the base 1.

[0051] After the fully enclosed slide has been used for a period of time, when the flexible steel belt 4 becomes loose relative to the opening side of the base 1, the flexible steel belt 4 can be tightened by adjusting one of the pressure plates 5 to facilitate operation.

[0052] Among them, the opening side is respectively provided with magnetic sealing strips 6 on two opposite sides in the length direction of the flexible steel strip 4, so that the magnetic sealing strip 6 can be used to downwardly suck the flexible steel strip 4 to seal the opening side, thereby improving the sealing matching relationship between the flexible steel strip 4 and the opening side of the base 1.

[0053] Since the motor mover 22 of the rod-shaped motor is a hollow structure, it is difficult to directly fix the motor mover 22 to the stage 3. For this reason, a mounting plate 23 is coated on the outer side of the motor mover 22, and the stage 3 is fixedly connected to the upper side of the mounting plate 23. Magnets 24 are respectively provided at both ends of the upper side of the mounting plate 23 to attract the flexible steel belt 4 downward, so as to further improve the sealing relationship between the flexible steel belt 4 and the opening side of the base 1.

[0054] In addition, a slide plate 25 with a slide groove is mounted on the bottom side of the mounting plate 23, and the bottom plate 12 is provided with a guide rail 121, and the slide plate 25 is slidably matched with the guide rail 121. The bottom plate 12 provides support for the motor mover 22, and the two are kept in sliding connection, so that the rod-shaped motor drives the stage 3 to move more smoothly and with higher movement accuracy.

[0055] Especially combined with Figure 1 As shown, the base 1 further includes a dust cover 7, which is arranged above the flexible steel belt 4 and fixedly connected to the loading platform 3. The dust cover 7 can be used to cover the junction of the flexible steel belt 4 and the loading platform 3 at both ends, so as to avoid the gap between the junction of the flexible steel belt 4 and the loading platform 3, which may cause dust inside the base 1 to overflow, so that the dust cover 7 cooperates with the flexible steel belt 4 to further improve the sealing performance of the opening side of the base 1.

[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
