Description of the Invention: [Technology of the Invention] The present invention relates to a linear module having a ball support supporting an upper cover, which is related to a work mechanism for generating linear motion. [Prior Art] With the advent of automation, most of the equipment is moving toward automated production. In many automation equipment, a linear module is often used, which can produce smooth linear motion and can be The linear module 10 includes a moving platform 11 linearly moving relative to a base 12 as shown in FIGS. 1 and 2, and the base 12 is further covered with an upper cover 13 . The two ends of the upper cover 13 are correspondingly locked to the two ends of the base 12, and since the upper cover 13 has only two ends of the base 12, the deformation of the downward deformation of the upper portion of the upper cover 13 occurs. In order to enable the middle portion of the upper cover 13 to be supported, as shown in FIG. 1, a support block A is disposed between the moving platform 11 and the upper cover 13, and the deformation amount of the middle portion of the upper cover 13 is provided by the branch block A. Although the degree of downward deformation of the middle portion of the upper cover 13 can be reduced, since the surface of the branch block A is flat, when the mobile platform 11 moves linearly, the branch block A on the mobile platform 11 is directly The direct contact with the upper cover 13 is such that the upper cover 13 is easily worn. In order to reduce the wear of the upper cover 13, please refer to the description of Fig. 2, 201120330, the mobile platform 1 丨 斜 oblique temple # u on the moving direction of the mobile platform 11 to set a plurality of rollers B' by rolling the sorrow The rolling contact with the upper jaw 13 reduces the wear rate of the upper cover 13 to extend the service life of the upper cover 13, however, the movement is flat. The '衮 wheel rim is set to correspond to the moving direction of the mobile platform 11', so that the money wheel can support the rolling direction of the mobile platform 11 in one direction, so that the linear module 1 cannot be used for multiple needs. In the light of the institutional system, in view of this, Lai Zuo people research and deeper conceived 'after many research and development trials, finally created a linear module with a ball support structure. SUMMARY OF THE INVENTION The purpose of the present invention is to provide a linear module for covering the upper surface of the seed ball support member, which reduces the friction between the ball support member and the upper cover by point contact, and can generate multi-directional Degree of freedom, increasing the applicability of use. For the purpose of the invention, the present invention provides a linear module having a cap of a ball-supported floor member, comprising: a base having two opposite end caps, and the connecting line of the two end caps is defined as a linear moving direction; a moving platform is slidably disposed between the one end cover of the base along the linear movement direction, and a plurality of support coupling holes are formed on one side of the moving platform; a plurality of ball support members are provided with a ball on a base body The ball protrudes from one side of the base body and is freely rotatable, and the balls support 201120330 pieces are received in the supporting joints of the moving platform by the base; and an upper cover and two ends The fixing group is disposed on the base, and the upper cover abuts against the balls of the ball support on the moving platform. Providing the ball support between the upper cover and the moving platform, the upper cover and the ball supporting member are in a point contact manner, thereby reducing the friction between the two and increasing the upper cover relative to the The freedom of the mobile platform to improve the applicability of the use. [Embodiment] In order to enable your review board to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, please refer to the following [detailed description of the drawings] as follows: The present invention has a ball support supporting the upper cover A preferred embodiment of the linear module, as shown in Figures 3 through 5, comprises: a base 20 having two opposite end caps 21, and the line connecting the two end caps 21 is defined as a linear movement direction X, and the two ends A guide rod 22 is disposed between the cover 21s. The guide rod 22 is disposed along the linear movement direction X^:, and the end cover 21 is respectively provided with a plurality of array holes 211, and the two sides of the guide rod 22 are respectively disposed a guide rail 23, the two rails 23 are parallel to the guide rod 22; a moving platform 30 is slidably disposed between the two end covers 21 in the base 20 along the linear movement direction, and the mobile platform 3〇 has a through hole 31 opened in the linear movement direction, the through hole 31 of the moving platform 3〇 is provided for the guide rod 22 of the base 20, and the moving platform 3〇 corresponds to the guide of the base 2032030 The second guide groove 32 is disposed in the second embodiment, and the two guide grooves 32 of the mobile platform 30 are correspondingly sleeved. On the guide rails 23, the moving platform 30 is slidable relative to the base 20 in the linear movement direction X, and the moving platform 30 has a plurality of support coupling holes 33 on a side opposite to the guide groove 32. The support member coupling hole 33 is stepped, and in this embodiment, four support member coupling holes 33 are provided, and the moving platform 30 has two opposite retaining walls 34 along the linear movement direction X. The two retaining walls 34 are disposed to form a receiving portion 35. The plurality of ball supporting members 40 are formed by a base 41 having a ball 42. The outer shape of the base 41 corresponds to the support on the moving platform 30. The engaging holes 33 are formed, and the balls 42 are protruded from one side of the base 41 and are freely rotatable, and the respective ball supporting members 40 are tightly received by the base 41 on the moving platform 30. The support member is combined with the hole 33; and an upper cover 50 is disposed on the base 20, and the upper cover 50 is opposite to each other. φ should be provided with a plurality of array holes 51 at both ends of the base 20, and the upper cover is provided by the multiple array member 52. The two ends of the 50 are fixedly disposed at two ends of the base 20, and the middle portion of the upper cover 50 Ball ball against the support member 30 on the mobile platform 40. The upper 42 and the cover 50 is received in the corresponding to the movement of the platform 30. Accommodating portion 35 between the inner wall 34 bis. The above is the structural relationship of the linear module having the ball support supporting the upper cover. When the linear module is used, the through hole 31 of the moving platform 30 is the guide rod 22 sleeved on the base 20, and the The guide groove 32 is a guide 23 for locating the 201120330 on the base 20, so that the moving platform 30 of the linear module can slide along the linear movement direction X on the base 20, and when the mobile platform 30 is on the base When the upper slide 20 is slid, the ball support 40 on the moving platform 30 can provide the downward deformation of the upper cover 50 to support the upper cover 50. Since the ball 42 can freely rotate on the base 41, the ball 42 can be freely rotated on the base 41. The rotating force of the ball 42 can simultaneously reduce the linear sliding resistance of the moving platform 30 relative to the upper cover 50, not only improving the smoothness of the linear displacement of the moving platform 30, but also the point of contact between the ball 42 and the upper cover 50. Moreover, the degree of wear between the upper cover 50 and the moving platform 30 can be minimized, and the service life of the upper cover 50 or the moving platform 30 can be extended, and since the balls 42 of the ball support 40 can be freely rotated, Therefore the ball 42 can provide multiple degrees of freedom between the upper cover 50 and the mobile platform 30, so that the upper cover 50 can be used for more variations, and the applicability of the linear module can be improved. 201120330 [Simple diagram of the diagram] Figure 1 is a schematic diagram of a planar support block between the upper cover and the mobile platform of the conventional linear module.
