For example, Chinese Patent CN210867362U discloses a fully sealed linear motor module. By cooperating with end plates, side cover plates and flexible steel belts to form a sealed space, the motor module is separated from the external space, effectively preventing dust in the air from falling in all directions; the linear motor is used to drive the loading table to slide, both ends of the flexible steel belt are fixedly connected to the end plates, pressing roller fixing frames are fixed at the front and rear ends of the loading table, and pressing rollers are hinged in the cavities of the pressing roller fixing frames. The flexible steel belt passes out from below the pressing rollers and passes above the loading table. However, the following deficiencies exist in this technical solution:

[0003] Since the flexible steel belt is arranged to pass through the loading table, tensile forces will be generated on different positions of the flexible steel belt during the movement of the motor module driving the loading table. During long-term use, it is easy to cause the sealing steel belt to be stretched and deformed, resulting in a decline in the sealing performance of the sealing steel belt. Summary of the Utility Model

[0004] The utility model aims to at least solve the problem that the sealing performance declines due to the stretching and deformation of the sealing steel belt in the prior art, and proposes a fully sealed linear motor module and a slide table thereof.

[0005] The utility model proposes a slide table of a fully sealed linear motor module, which includes a loading table and a sealing belt; the loading table includes a sliding seat, a first rolling guide assembly arranged on the sliding seat, and two second rolling guide assemblies respectively arranged at two opposite ends of the sliding seat. The sealing belt is arranged to pass out from the gap between the second rolling guide assembly and the end of the sliding seat; the end of each second rolling guide assembly is fixedly connected to the corresponding end of the sliding seat through an adjusting arm. The first end of the adjusting arm is fixedly connected to the second rolling guide assembly, and the second end of the adjusting arm is fixedly connected to the end of the sliding seat through an angle swinging structure.

[0008] In some preferred embodiments, the angular swing structure further includes a first locking hole provided at the end of the sliding seat, a second locking hole correspondingly provided at the second end of the adjusting arm, and a second fixing member passing through the second locking hole and locking with the first locking hole; the first locking hole is arranged farther from the second rolling guide assembly relative to the first fixing hole.

[0009] In some preferred embodiments, a reinforcing plate is provided above the second rolling guide assembly, and the ends of the reinforcing plate are respectively fixedly connected to the first end of the adjusting arm.

[0023] To further elaborate on the technical means and effects adopted by this application to achieve the intended purpose, the following, in combination with the attached drawings and preferred embodiments, details the specific implementation manners, structures, features, and their effects according to this application. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0024] Combined with Figures 1-3 As shown, the fully sealed linear motor module specifically includes a machine housing 1 and a linear motor 2 fixed inside the machine housing 1. The top surface of the machine housing 1 has a through groove 11 that is consistent with the movement direction of the linear motor 2; a sliding table driven by the linear motor 2 is provided in the through groove 11.

[0025] Specifically, the sliding table includes a material loading table 3 and a sealing belt 4. The material loading table 3 is used to place workpieces. The material loading table 3 is slidably arranged in the through groove 11, and the material loading table 3 is fixedly connected to the mover of the linear motor 2. The linear motor 2 drives the material loading table 3 to drive the workpieces to move linearly as required in the through groove 11; the two ends of the sealing belt 4 in the length direction are respectively fixed at the two ends of the machine housing 1, and the sealing belt 4 passes through the material loading table 3 and covers the through groove 11, using the sealing belt 4 to seal the through groove 11 to prevent the particulate dust generated during the movement of the linear motor 2 from overflowing through the through groove 11.

[0026] In order to make the material loading table 3 slide smoothly on the through groove 11, slide rails can be provided on the two opposite sides of the through groove 11, and the two opposite sides of the material loading table 3 are slidably connected to the slide rails.

[0027] In order to make the two side edges of the sealing belt 4 keep a tight fit between the two opposite side edges of the through groove 11 in the length direction to improve the sealing effect, usually the sealing belt 4 is made of a magnetic steel belt, and magnetic strips are provided on the two opposite side edges of the through groove 11 in the length direction to generate magnetic attraction for the sealing belt 4 through magnets, so that the sealing belt 4 can better seal the through groove 11.

[0028] Further combine Figures 3-6 As shown, the material loading table 3 specifically includes a sliding seat 31, a first rolling guide assembly 32 arranged on the sliding seat 31, and two second rolling guide assemblies 33 respectively arranged at two opposite ends of the sliding seat 31. Each second rolling guide assembly 33 is fixedly connected to the corresponding end of the sliding seat 31 through an adjusting arm 34 at the end of the central axis respectively.

[0029] In order to improve the connection strength between the second rolling guide assembly 33 and the adjusting arm 34, a reinforcing plate 35 is arranged above each second rolling guide assembly 33, and the two ends of the reinforcing plate 35 are respectively fixedly connected to the first ends of the two adjusting arms 34.

[0030] There is a gap between each second rolling guide assembly 33 and the corresponding end of the sliding seat 31; the end of the sealing belt 4 passes out from the sliding seat 31 downward through the gap between the second rolling guide assembly 33 and the end of the sliding seat 31 and is fixed to the end of the machine housing 1.

[0031] The first rolling guide assembly 32 abuts against the lower side surface of the sealing belt 4, and the second rolling guide assembly 33 presses on the upper side surface of the sealing belt 4, reducing the gap between the side of the sealing belt 4 and the side of the through groove 11, so that the sealing belt 4 seals the through groove 11 as much as possible.

[0032] During the linear movement of the material loading table 3 in the through groove 11 driven by the linear motor 2, the material loading table 3 rolls by abutting against the lower side surface of the sealing belt 4 through the first rolling guide assembly 32 and rolls by pressing on the upper side surface of the sealing belt 4 through the second rolling guide assembly 33, which can reduce the friction between the material loading table 3 and the sealing belt 4, make the movement of the material loading table 3 smoother, and at the same time can also reduce the wear of the sealing belt 4.

[0033] The sliding seat 31 includes two relatively arranged sliding rods 311 and a sealing plate 312 fixed between the two sliding rods 311. The two sliding rods 311 are respectively slidably connected to the long side edges of the through groove 11, and the bottom of the sealing plate 312 is fixedly connected to the mover of the linear motor 2. The mover of the linear motor 2 drives the whole sliding seat 31 to make a linear movement in the through groove 11 through the sealing plate 312.

[0034] The two ends of the first rolling guide assembly 32 in the central axis are respectively fixedly connected to the two sliding rods 311, and the upper surface of the first rolling guide assembly 32 is higher than the upper surface of the sealing plate 32, so that when the sealing belt 4 covers and passes through the sealing plate 312, it contacts the lower side surface of the sealing belt 4 through the first rolling guide assembly 32, and as much as possible avoids the contact between the sealing plate 312 and the sealing belt 4 to reduce the sliding resistance generated by the sealing belt 4 on the material loading table 3 during the sliding process.

[0035] As shown in the attached drawings, first rolling guide assemblies 32 are respectively provided at both ends of the sealing plate 312 located between the two sliding rods 311. Or / and, in other embodiments, a first rolling guide assembly 32 may also be provided in the middle of the sealing plate 312.

[0036] Among them, both the first rolling guide assembly 32 and the second rolling guide assembly 33 are rollers or roller wheels.

[0037] Specifically, the first end of each adjusting arm 34 is fixedly connected to one end of a second rolling guide assembly 33, and the second end of the adjusting arm 34 is fixedly connected to the end of the slide base 31 through an angular swing structure. Through the angular swing structure, the fixed angle between the second end of the adjusting arm 34 and the end of the slide base 31 can be adjusted as needed, correspondingly adjusting the position of the first end of the adjusting arm 34 relative to the slide base 31 in the up and down directions, so as to adjust the position of the second rolling guide assembly 33 relative to the slide base 31 in the up and down directions, ensuring that the second rolling guide assembly 33 presses down on the sealing belt 4 to keep a reliable sealed connection between the long side of the sealing belt 4 and the long side of the through groove 11.

[0038] After the fully sealed linear motor has been used for a long time, when the sealing belt 4 is stretched and deformed due to the tensile force generated by continuous repeated sliding on the loading table 3, it may cause a gap between the positions of the sealing belt 4 near the two ends of the loading table 3 and the through groove 11, resulting in a decrease in sealing performance. At this time, the fixed angle between the second end of the adjusting arm 34 and the end of the slide base 31 can be increased through the angular swing structure, thereby increasing the distance between the second rolling guide assembly 33 below the slide base 31, so that the second rolling guide assembly 33 increases the pressing degree on the sealing belt 4, and the long side of the deformed and elongated sealing belt 4 and the long side of the through groove 11 can still maintain a reliable sealed connection.

[0039] In a preferred embodiment, the angular swing structure includes a first fixing hole 301 provided at the end of the sliding rod 311 of the slide base 31, an adjusting hole 341 correspondingly provided at the second end of the adjusting arm 34, and a first fixing member passing through the adjusting hole 341 and fixedly connected to the first fixing hole 301. When the first fixing member is at different positions in the adjusting hole 341, the swing angle between the adjusting arm 34 and the sliding rod 311 can be correspondingly adjusted.

[0040] Among them, the adjusting hole 341 is a non-circular hole extending in the direction in which the adjusting arm 34 can swing relative to the slide base 31. The adjusting hole 341 is usually an elliptical hole, a strip-shaped hole or an arc-shaped hole.

[0041] In a preferred embodiment, the angular swing structure further includes a first locking hole 302 provided at the end of the sliding rod 311 of the sliding seat 31, a second locking hole 342 correspondingly provided at the second end of the adjusting arm 34, and a second fixing member passing through the second locking hole 342 and locking with the first locking hole 302; the first locking hole 302 is arranged farther from the second rolling guide assembly 33 than the first fixing hole 301.

[0042] The second end of the adjusting arm 34 is locked with the first locking hole 302 by the second fixing member passing through the second locking hole 342, which can improve the fixed connection strength between the second end of the adjusting arm 34 and the end of the sliding rod 311 and prevent loosening.

[0043] When it is necessary to adjust the swing angle of the adjusting arm 34, first loosen the second fixing member, remove the first fixing member, and then the second end of the adjusting arm 34 can rotate or swing relative to the end of the sliding rod 311 with the second fixing member as the rotation axis. When the adjusting arm 34 swings to a suitable angle relative to the end of the sliding rod 311, tighten the second fixing member and insert the first fixing member into the adjusting hole 341 and the first fixing hole 301 for fixation. The operation is simple and convenient to use.

[0044] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
