Description

[0004] In the current design of high-precision linear motion stage modules, the guide rails and drive mechanisms are mostly set separately. Although this improves the flexibility of the module to a certain extent, it also increases the complexity of assembly and the source of errors.

Secondly, many high-precision linear motion stage modules are equipped with cross-ball tracks. Although this design improves the load-bearing capacity and movement smoothness of the guide rails to a certain extent, its structure is complex and it is difficult to process and assemble, which further increases the cost and error of the module.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] See also Figure 1 , Figure 2 and Figure 3 The present invention provides a technical solution: a precisely positioned mobile stage module, comprising a base 100 and a mobile seat 300 assembled on the top of the base 100 through a parallel sliding of an integrated guide rail unit 200, wherein the integrated guide rail unit 200 comprises: a mounting groove 210, which is fixedly mounted on the top surface of the base 100 along the length direction of the base 100 and is a basic support structure of the integrated guide rail unit 200, a slide seat 240, which is slidably assembled on the top of the mounting groove 210 and provides structural support for the installation of the mobile seat 300, a driving mechanism 250, which is erected inside the mounting groove 210 along the length direction of the mounting groove 210 and provides a power source for the movement of the slide seat 240, a first fine-tuning guide mechanism 220 and a second fine-tuning guide mechanism 230, which are relatively arranged and assembled on the mounting groove 210 and provide precise guidance for the movement of the slide seat 240.

[0053] Based on the above-mentioned structural setting, the precisely positioned mobile stage module is composed of a base 100, an integrated guide rail unit 200 and a mobile seat 300, wherein the base 100 provides a stable basic support for the entire module, the integrated guide rail unit 200 integrates a guide rail and a drive mechanism 250, which is used to support and guide the mobile seat 300 to slide smoothly and accurately, and the mobile seat 300 is used to carry a workpiece or an actuator. Specifically, during the working process, the operator first adjusts the first fine-tuning guide mechanism 220 and the second fine-tuning guide mechanism 230 to fine-tune the guide rail to the desired position to ensure the positioning accuracy of the mobile seat 300, and then starts the drive mechanism 2 50, so as to drive the slide 240 to slide on the installation groove 210. At this time, the first fine-tuning guide mechanism 220 and the second fine-tuning guide mechanism 230 have accurately guided the slide 240 to ensure the stability and accuracy of the slide 240 during the sliding process. The precisely positioned mobile carrier module is provided with an integrated guide rail unit 200, which integrates the guide rail with the driving mechanism 250, effectively reducing the assembly error, thereby improving the positioning accuracy and stability of the module. At the same time, with the help of the first fine-tuning guide mechanism 220 and the second fine-tuning guide mechanism 230, the guiding accuracy of the slide 240 can be further improved, ensuring the high-precision positioning of the moving seat 300.

[0054] For further information, see Figure 4 and Figure 5The driving mechanism 250 includes two symmetrically distributed end seats 2510 respectively fixedly installed at both ends of the mounting groove 210, a synchronous belt transmission assembly 2520 mounted between the two end seats 2510, and a servo motor 2530 fixedly installed on the side of one of the end seats 2510 for the synchronous belt transmission assembly 2520 to move. The slide 240 is fixedly installed on the top of the synchronous belt of the synchronous belt transmission assembly 2520 through the connecting fitting 260. Among them, the driving mechanism 250 adopts the synchronous belt transmission assembly 2520 and the servo motor 2530 to achieve precise driving and control of the slide 240, and improve the operating efficiency and stability of the mobile platform module. Specifically, when the servo motor 2530 is started, the synchronous belt transmission assembly 2520 can drive the slide 240 assembled on the top of the synchronous belt through the connecting fitting 260 to slide stably along the first fine-tuning guide mechanism 220 and the second fine-tuning guide mechanism 230.

[0055] For further information, see Figure 6 The top of the connection fitting 260 is provided with a groove 2610 for the synchronous belt of the synchronous belt transmission assembly 2520 to accommodate, and both ends of the groove 2610 are provided with a flaring structure 2620. The connection fitting 260 uses the groove 2610 to press the synchronous belt of the synchronous belt transmission assembly 2520 against the bottom of the slide 240, thereby achieving fixed installation of the slide 240 on the synchronous belt. Specifically, the setting of the flaring structure 2620 facilitates the convenient disassembly and assembly of the synchronous belt.

[0056] For further information, see Figure 7 The first fine-tuning guide mechanism 220 is composed of a fixed clip 2210 provided at the top of one inner side surface of the installation groove 210 and clipped with one side of the connection accessory 260, two support blocks 2220 respectively provided at both ends of the other side surface of the installation groove 210, and a first fine-tuning guide rail 2230 slidably mounted on the two support blocks 2220. The first fine-tuning guide mechanism 220 is used for guiding and limiting the slide 240 on the inner side structure of the installation groove 210, that is, to ensure the stable movement of the slide 240 driven by the synchronous belt transmission assembly 2520. Specifically, the slide 240 cooperates with the connection accessory 260 on one side to achieve stable support and guiding and limiting with the help of the fixed clip 2210, and the slide 240 cooperates with the connection accessory 260 on the other side to achieve support and limiting with the help of the first fine-tuning guide rail 2230.

[0057] For further information, see Figure 8The first fine-tuning guide rail 2230 includes an active clip 2231 that is fitted into the side of the connecting accessory 260 and a first connecting plate 2232 that is fixedly installed on the outer side of the active clip 2231, and a first screw rod 2233 with a vertical thread passing through one side of the mounting groove 210. The inner end of the first screw rod 2233 extends into the mounting groove 210 and is rotatably connected to the first connecting plate 2232. A first hand wheel 2234 is fixedly installed on the outer end of the first screw rod 2233. First guide columns 2235 that can movably pass through one side of the mounting groove 210 are vertically provided on the outer surface of the first connecting plate 2232 and on both sides of the first screw rod 2233. Among them, in the first fine-tuning guide mechanism 220, the setting of the fixed clip 2210 and the movable clip 2231 can ensure the stability of the connecting accessory 260 and the slide 240 during the movement, and the cooperation of the first screw rod 2233 and the two first guide columns 2235 can realize the fine adjustment of the position of the slide 240. Specifically, the operator can drive the first connecting plate 2232 with the help of the first screw rod 2233 to drive the movable clip 2231 to move stably under the guidance of the two first guide columns 2235, thereby realizing the fine adjustment of the slide 240.

[0058] For further information, see Fig. 9 The second fine-tuning guide mechanism 230 is composed of a linear needle roller guide rail 2310 and a V-shaped guide bar 2320 respectively arranged on the top of the two outer sides of the mounting groove 210, and a second fine-tuning guide rail 2330 mounted on an inner side of the slide 240. The second fine-tuning guide mechanism 230 is used for guiding and limiting the slide 240 on the outer side of the mounting groove 210, that is, to ensure that the slide 240 moves stably on the mounting groove 210. Specifically, the linear needle roller guide rail 2310 provides stable support and limiting guidance for one side of the slide 240, while the second fine-tuning guide rail 2330 provides support and limiting for the other side of the slide 240. The first fine-tuning guide mechanism 220 and the second fine-tuning guide mechanism 230 are arranged and assembled on the mounting groove 210 in a relative manner. On the one hand, the layout is reasonable and convenient for the operation of the two. On the other hand, the first fine-tuning guide mechanism 220 and the second fine-tuning guide mechanism 230 are used in combination to achieve precise control of the movement of the slide 240.

[0059] For further information, see Fig.10The second fine-tuning guide rail 2330 includes a V-shaped needle roller guide rail 2331 adapted to the V-shaped guide bar 2320 and a second connecting plate 2332 fixedly installed on the outer side of the V-shaped needle roller guide rail 2331, and a second screw rod 2333 with a vertical thread passing through one side of the slide 240. The inner end of the second screw rod 2333 extends into the slide 240 and is rotatably connected to the second connecting plate 2332. A second hand wheel 2334 is fixedly installed on the outer end of the second screw rod 2333. Second guide columns 2335 that can movably pass through one side of the slide 240 are vertically provided on the outer surface of the second connecting plate 2332 and on both sides of the second screw rod 2333. Among them, in the second fine-tuning guide mechanism 230, the cooperation between the linear needle roller guide 2310 and the V-shaped needle roller guide 2331 and the V-shaped guide strip 2320 can ensure the stability of the movement of the slide 240 on the mounting groove 210, and the cooperation between the second screw rod 2333 and the two second guide pillars 2335 can realize the fine adjustment of the position of the slide 240. Specifically, the operator can drive the second connecting plate 2332 to drive the V-shaped needle roller guide 2331 to move stably under the guidance of the two second guide pillars 2335 by turning the second hand wheel 2334.

[0060] For further information, see Fig.11 , and also includes two first laser distance measuring sensors 2410 respectively sunk and installed on both sides of the top of the slide 240. Second laser distance measuring sensors 2430 are installed on both sides of the slide 240 through the height detection bracket 2420, and the two second laser distance measuring sensors 2430 are arranged diagonally. Among them, by setting the first laser distance measuring sensor 2410 and the second laser distance measuring sensor 2430 on the slide 240, they are respectively used to monitor the position of the slide 240 and the state of the moving seat 300 in real time. Specifically, the two first laser distance measuring sensors 2410 are sunk and installed on both sides of the slide 240, and can respectively detect the distance between the two sides of the slide 240 and the adjacent end seat 2510. During the movement of the slide 240, the distance of one first laser distance measuring sensor 2410 increases, and the moving distance of the slide 240 can be recorded, while the distance of the other first laser distance measuring sensor 2410 decreases, which can be used for data verification. In addition, in the set Within the error threshold, the module accuracy can be evaluated by monitoring data. The two second laser ranging sensors 2430 are arranged diagonally and installed on both sides of the slide 240 respectively, for real-time monitoring of the assembly flatness of the moving seat 300. The detection windows of the two second laser ranging sensors 2430 are arranged vertically upward, which means that they can measure and record the vertical distance between the bottom surface of the moving seat 300 in real time. When the data collected by the two second laser ranging sensors 2430 are consistent within the preset error threshold, it means that the assembly flatness of the moving seat 300 meets the expected accuracy requirements. Otherwise, the operator needs to adjust the moving seat 300.

[0061] For further information, see Fig.12 , the inner sides of the tops of the two end seats 2510 are provided with bosses 2511, and the inner sides of the two bosses 2511 are provided with two buffer pads 2512. Among them, by providing the bosses 2511 and the buffer pads 2512 on the inner sides of the tops of the end seats 2510, the impact and vibration of the slide seat 240 during the sliding process can be effectively reduced.

[0062] For further information, see Fig.13 , and also includes two locking assemblies 270 for positioning the first fine-tuning guide rail 2230 and the second fine-tuning guide rail 2330 respectively, the locking assembly 270 includes a locking block 2710, a bayonet 2720 for the first screw rod 2233 or the second screw rod 2333 to movably pass through the middle of the locking block 2710, and a screw rod 2730 vertically penetrated and assembled on one side of the locking block 2710, an adjustment slot 2740 extending radially along the bayonet 2720 is horizontally opened on the locking block 2710, the bottom end of the screw rod 2730 movably passes through the upper part of the adjustment slot 2740 and is threadedly connected to the lower part of the adjustment slot 2740, and a handle 2750 is fixedly installed on the top of the screw rod 2730. Among them, the two locking assemblies 270 are respectively used to position and lock the first fine-tuning guide rail 2230 and the second fine-tuning guide rail 2330 to ensure their stability and accuracy during operation. Specifically, when the position of the first fine-tuning guide rail 2230 or the second fine-tuning guide rail 2330 needs to be adjusted, the corresponding locking assembly 270 can be operated. Specifically, first, the screw 2730 is loosened upwards with the help of the handle 2750. When the adjustment of the first fine-tuning guide rail 2230 or the second fine-tuning guide rail 2330 is completed, the screw 2730 is tightened downwards, and the end of the first screw rod 2233 or the second screw rod 2333 is clamped with the bayonet 2720 to fix it and no longer rotate, thereby further enhancing the stability of the module.
