DETAILED DESCRIPTION

[0029] Please refer to Figures 1 to 7 , which is a vertical slide provided by a preferred embodiment of the present invention, mainly includes a column 10, two slide grooves 20, four slide seats 30 and a carrier 40. The number of these components can be changed according to demand, especially the slide grooves 20 and the slide seat 30.

[0030] The column 10 defines a virtual X-axis direction, a Y-axis direction, and a Z-axis direction, and substantially extends along the Z-axis direction and has a vertical columnar structure.

[0031] Each of the slide grooves 20 is recessed on two opposite sides of the column 10 and extends along the Z axis.

[0032] Each of the slide seats 30 is located in the corresponding slide slot 20, and each of the slide seats 30 includes a body 31, a first roller 32, an adjustment mechanism 33, two second rollers 34, two third rollers 35, a first mounting groove 36, two second mounting grooves 37 and two third mounting grooves 38, wherein the body 31 extends along the X-axis, the Y-axis and the Z-axis to form a rectangular parallelepiped shape, and has a first surface 311, a second surface 312, a third surface 313, a fourth surface 314, a fifth surface 315 and a sixth surface 316. Furthermore, the first mounting groove 36, the second mounting grooves 37 and the third mounting grooves 38 are respectively recessed at different positions on the body 31, and the number, size or position can be arbitrarily changed according to demand. In this example, the first mounting groove 36 is recessed on the body 31 and straddles the first surface 311 of the body 31 and the second surface 312 and the fourth surface 314 adjacent to the first surface 311. Each of the third mounting grooves 38 is recessed on the body 31 and straddles the third surface 313 of the body 31 and the fifth surface 315 or the sixth surface 316 adjacent to the first surface 311. Each of the second mounting grooves 37 is respectively disposed at an end corner position of the body 31. Moreover, the shapes of the spaces in the mounting grooves are similar to the contours of the components to be accommodated therein.

[0033] The adjustment mechanism 33 is accommodated in the first installation groove 36 for assembling and adjusting the first roller 32. Specifically, the adjustment mechanism 33 has a pivoting portion 331 and an adjusting portion 332, wherein the pivoting portion 331 has two sets of seats 3311, which are arranged in the first installation groove 36 on the main body 31 at a predetermined distance, and an accommodation space 3312 is formed between the two sets for accommodating the first roller 32, and the axis of the wheel axle 321 of the first roller 32 is pivoted on each of the seats 3311 along the Y-axis direction, and a part of the first roller 32 protrudes from the first installation groove 36 and is exposed outside the main body 31, as shown in FIG. Figure 3 , Figure 5 and Figure 6 shown.

[0034] Specifically, each of the base bodies 3311 includes two clamping members 33111 and two recesses 33112, wherein the two clamping members 33111 are used to clamp the axle 321 of the first roller 32, and each of the recesses 33112 is respectively recessed on a side surface of each of the clamping members 33111 facing the axle 321, and the curvature of each of the recesses 33112 is similar to the curvature of the axle 321 of the first roller 32, so that each of the base bodies 3311 can clamp the axle 321. Figure 4 and Figure 5 Furthermore, the clamping members 33111 are relatively far away from one of the main bodies 31 and are fixed to the main body 31 by at least one fastener 33113 .

[0035] The adjustment portion 332 includes an adjustment hole 3321 and an adjustment member 3322. The adjustment hole 3321 penetrates the main body 31 from the third surface 313 toward the first surface 311, and one end of the adjustment hole 3321 is opened to be located at the bottom 361 of the first mounting groove 36 and within the range covered by the position of the pivoting portion 331. The adjustment member 3322 is movably inserted into the adjustment hole 3321 and can perform linear displacement relative to the main body 31 and within the adjustment hole 3321, so that one end of the adjustment member 3322 protrudes from the adjustment hole 3321 and is exposed outside the main body 31, and abuts against the pivoting portion 331, thereby limiting the distance between the pivoting portion 331 and the main body 31, thereby adjusting the distance between the main body 31 and the first roller 32, such as Figure 4 , Figure 5 and Figure 6 shown.

[0036] The axis of the second roller 34 is pivotally mounted on the body 31 along the Z-axis direction and is located in the second mounting groove, so that a portion of the second roller 34 protrudes from the second mounting groove 37 and is exposed outside the body 31 .

[0037] The axis of the third roller 35 is pivotally mounted on the body 31 along the Y-axis direction and located in the third mounting groove, so that a portion of the third roller 35 protrudes from the third mounting groove 38 and is exposed outside the third surface 313 and the fifth surface 315 or the sixth surface 316 of the body 31.

[0038] In addition, the number, size, position or installation direction of the rollers can be changed as required to achieve a predictable effect.

[0039] According to the description of the slide 30, when each slide 30 is located in the corresponding slide groove 20, the first roller 32 and the third roller 35 are respectively slidably disposed on the two opposite groove walls 21 of the slide groove 20, and the second roller 34 is slidably disposed on the bottom surface of the groove bottom 22 of the slide groove 20, so that the movement of the slide 30 in the slide groove 20 is stably supported, such as Figure 7 shown.

[0040] The carrier 40 is composed of a plurality of plates 41, and forms a U-shaped structure, which can be sleeved on the column 10, and the inner wall surfaces 411 of the two facing plates 41 are respectively close to the notches of the slide grooves 20, and respectively connected with the corresponding slide seats 30, and the number of the slide seats 30 can be two, four or an even multiple, depending on the overall size of the plates 41. In this way, sliding friction between the carrier 40 and other components can be avoided.

[0041] Furthermore, the carrier 40 is driven by a power mechanism 50 and can move in the Z-axis direction. In this example, the power mechanism 50 includes a rack 51 and a drive motor 52. The rack 51 is arranged on the column 10 along the extending direction of the column 10. The drive motor 52 is arranged on the carrier 40 and has a roller gear at its output end, which is meshed with the rack 51.

[0042] Accordingly, the present invention can stably support the vertical structure in the moving direction, not limited to the gravity direction or the horizontal direction, and can avoid sliding friction between components. In addition to extending the service life, it can also avoid the reduction in precision due to wear.

[0043] Furthermore, the present invention can withstand higher speed movement, that is, the maximum speed: 3000mm / s, the noise is below 70 decibels, and the position repeatability is ±0.005mm, so as to improve the moving speed and noise of the known slide module and meet the requirements of specific applications. The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if it does not depart from the scope of the technical features of the present invention, uses the equivalent embodiments of the technical content disclosed by the present invention to make partial changes or modifications, which still fall within the scope of the technical features of the present invention.
