[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , a super-large dual-drive repair high-precision motion platform, including a support platform 1, on which a host for controlling the working mode is installed, a horizontal mover 2 is installed above the support platform 1, and drivers 3 are installed on both sides of the support platform 1. The drivers 3 drive the horizontal mover 2 from both sides. A longitudinal mover 4 is installed on the horizontal mover 2. The moving direction of the longitudinal mover 4 is perpendicular to that of the horizontal mover 2, and the longitudinal mover 4 is used to connect a detection or repair device;

[0025] The outer surface of the support platform 1 is provided with a number of disorderly arranged attitude repair mechanisms 6, which can improve the contact points with the bottom of the product and provide more control points to control the attitude repair of the product. The number of disorderly arranged attitude repair mechanisms 6 can all be individually driven to adjust and repair the attitude of the article;

[0026] The posture repair mechanism 6 includes a stepper motor 601 installed inside the support platform 1. The output shaft of the stepper motor 601 is connected to a speed reducer 602, and the output shaft of the speed reducer 602 is connected to a driving roller 603. A driven roller 604 is driven on the outer surface of the driving roller 603, and the outer surface of the driven roller 604 extends to the top of the support platform 1.

[0027] Through the above technical solution, a stepper motor 601 is arranged inside the support platform 1 to drive the driving roller 603. At the same time, the driving roller 603 drives the driven roller 604 to rotate. When the product on the surface of the support platform 1 deviates, the driven roller 604 at the corresponding angle will drive the product to move, realizing the posture adjustment and repair of the product, so as to improve the accuracy of product detection and repair.

[0028] Moreover, the two sets of drivers 3 can better push the gantry-style horizontal mover 2 to move, and have higher stability when dealing with super-large products.

[0029] The above-mentioned horizontal mover 2 and vertical mover 4 have the same structure and driving method as the prior art. Therefore, they will not be described in detail in the application documents and the drawings.

[0030] Specifically, several stepper motors 601 are individually connected to the host of the support platform 1 through data lines.

[0031] Through the above technical solution, if all the stepper motors 601 are individually controlled, different-direction movements can be performed through multiple driven rollers 604, so as to achieve diversified angle control and thus more precise product posture adjustment.

[0032] Specifically, there is an included angle between the driven rollers 604, and the outer surface heights of the driven rollers 604 are equal.

[0033] Through the above technical solution, the included angle is set between the driven rollers 604, so that more distribution directions can be achieved, and a driven roller 604 for adjusting the product posture is provided in each direction, so as to improve the accuracy of product posture adjustment and repair.

[0034] Specifically, the outer surfaces of the driving roller 603 and the driven roller 604 are both provided with concave and convex patterns. The outer surface of the driving roller 603 is rigid, and the outer surface of the driven roller 604 is flexible.

[0035] Through the above technical solution, concave and convex patterns are provided on the outer surfaces of the driving roller 603 and the driven roller 604, aiming to increase the friction between the driving roller 603 and the driven roller 604, so that the driving of the driven roller 604 by the driving roller 603 is more stable. The outer surface of the driven roller 604 is set to be flexible because the driven roller 604 will directly contact the product, and the flexible outer surface can better protect the product.

[0036] Specifically, moving guide grooves 101 are also provided on both sides of the top of the support platform 1. Fixed-point devices 5 are symmetrically installed inside the moving guide grooves 101, and the fixed-point devices 5 emit and receive infrared rays.

[0037] Through the above technical solution, the purpose of setting the moving guide grooves 101 is to conduct moving guidance, so that the fixed-point devices 5 can only move along the trajectory of the moving guide grooves 101, ensuring that the fixed-point devices 5 on both sides are parallel.

[0038] Specifically, limiting grooves 102 are provided on both sides of the moving guide grooves 101. Tooth rows 103 are arranged on the side surfaces of the limiting grooves 102, and wire grooves 104 are provided at the bottom of the moving guide grooves 101;

[0039] The fixed-point device 5 includes an infrared transmitting / receiving device 501. The infrared transmitting / receiving device 501 includes a transmitting end and a receiving end, and is used in pairs. Transmitting / receiving windows 502 are arranged on the opposite surfaces of two symmetrically distributed infrared transmitting / receiving devices 501. Support feet 503 are fixedly connected to the bottom of the infrared transmitting / receiving device 501, and the support feet 503 extend into the limiting grooves 102 and are limited. A transmission gear roller 504 is installed at the bottom of the infrared transmitting / receiving device 501. The transmission gear roller 504 is driven by a servo motor inside the infrared transmitting / receiving device 501, and the transmission gear roller 504 also meshes with the tooth row 103. A power supply data wire 505 is also provided at the bottom of the infrared transmitting / receiving device 501. The power supply data wire 505 passes through the wire groove 104 and extends into the support platform 1 to be controlled by the host of the support platform 1.

[0040] Through the above technical solution, the limiting grooves 102 and the support feet 503 are cooperated, so that the infrared transmitting / receiving device 501 can move without deviation and tilt. During use, by setting the distances between the left and right infrared transmitting / receiving devices 501 and the axis line of the moving platform, the servo motor inside the infrared transmitting / receiving device 501 drives the transmission gear roller 504 to rotate. The rotating transmission gear roller 504 cooperates with the tooth row 103, so that the infrared transmitting / receiving device 501 changes its direction to be horizontal with the edge of the product. When the product tilts or deviates, the infrared rays emitted by the transmitting / receiving window 502 will be blocked. The direction of tilting or deviation of the product is determined by the blocking direction, and then the corresponding stepping motor 601 is controlled to change the direction of the driven roller 604 to achieve the effect of automatically repairing the product posture.

[0041] In use, a stepper motor 601 is arranged inside the support platform 1 to drive the driving roller 603. Meanwhile, the driving roller 603 drives the driven roller 604 to rotate. When the product on the surface of the support platform 1 is offset, the driven roller 604 at the corresponding angle drives the product to move, realizing the attitude adjustment of the product, so as to improve the accuracy of product detection and repair.

[0042] The infrared emission / reception device 501 is supported and limited by arranging moving guide grooves 101 at both ends of the support platform 1. During use, the infrared rays emitted by the infrared emission / reception device 501 are emitted along the edge of the product. The paired infrared emission / reception devices 501 receive the infrared signals. When the infrared signal on one side is blocked, the infrared emission / reception device 501 sends an instruction to the stepper motor 601 at the corresponding position, causing the driven roller 604 at the corresponding angle to work to adjust the attitude of the product, achieving the effect of automatically repairing the attitude of the product.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
