Description

Technical Field

[0001] The present invention relates to the technical field of high-precision and high-stability transmission of photographed objects in machine vision, and in particular to a single-support transmission device for high-precision transmission. Background Art

[0002] Machine vision is a rapidly developing branch of artificial intelligence. Simply put, machine vision is the use of machines to replace human eyes for measurement and judgment. The machine vision system uses machine vision products (i.e., image capture devices, which are divided into CMOS and CCD) to convert the captured target into an image signal, transmit it to a dedicated image processing system, obtain the morphological information of the captured target, and convert it into a digital signal based on pixel distribution, brightness, color and other information; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the action of the equipment on site based on the judgment results. For example, transmission cover glass, small metal sheets (such as the back cover of a CNC-processed mobile phone), solar silicon wafers, wafers, etc. require machine vision to detect whether their surfaces are damaged, etc.

[0003] For high-precision and high-stability object transmission, the O-ring + roller method is used for rotation: this method puts an O-ring between two parallel rollers, and the O-ring moves with the rotation of the roller. The object is placed on the O-ring to achieve the translation of the object. Since the O-ring is a consumable item, it needs to be replaced with a new O-ring after a period of use. At this time, the double fixed support solution will make the replacement of the O-ring time-consuming and labor-intensive, and the system maintenance cost is high. Therefore, the single fixed support method will be used as the main support for the O-ring solution. During use, there is a certain amount of clearance between the roller and the bearing. When the object is transmitted from one O-ring module to another O-ring module, the object will generate a downward load pressure on the roller. Since the load on the roller will change dynamically when the object moves from one module to another, the roller will vibrate up and down due to the existence of clearance, thereby reducing the stability and accuracy of the transmission.

[0004] Therefore, it is necessary to provide a single-support transmission device for high-precision transmission to solve the above technical problems. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a single-support transmission device for high-precision transmission.

[0011] Compared with the related art, the single-support transmission device for high-precision transmission provided by the present invention has the following beneficial effects:

[0012] The present invention provides a single-support transmission device for high-precision transmission:

[0013] When in use, the O-ring is put in the groove structure of the pulley for transmission, and the workpiece is transmitted through the two O-rings. When the workpiece is transported to the first roller and the second roller, due to the effect of gravity, one end of the first roller has a certain amount of offset downward, which will cause the workpiece transmission to be deflected. When the workpiece passes through a first roller, the controller controls the electromagnet to be energized to generate magnetic force, which can adsorb the magnetic ring and apply a balancing force to the end of the first roller away from the second roller to offset the force pressed down by the weight of the workpiece. As the workpiece assembly moves away from the first roller, the controller controls the magnetic force of the electromagnet to gradually decrease, so that the offset of the first roller can always be kept within a certain range, reducing the vibration of the first roller. When the workpiece moves from one end to the other, the load on the first roller will gradually decrease, while it will gradually increase when it reaches the second roller. At this time, the controller will control the two electromagnets so that the changing loads of the two first rollers can be offset, thereby ensuring that the object is stable during the transmission process, thereby improving the accuracy and stability of the entire transmission system. This device has high transmission accuracy and stability, and is convenient for people to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Please refer to Figure 2 As shown, the load adjustment device 8 includes a magnetic ring 81, a first mounting seat 82, a first fixed shaft 83, an electromagnet 84 and a controller 85. The end of the first roller 3 away from the second roller 5 passes through the side plate 1 and is fixed with the magnetic ring 81. The side of the side plate 1 away from the bottom plate 2 is fixed with the first mounting seat 82. The two first mounting seats 82 are fixed with the first fixed shaft 83. The two ends of the first fixed shaft 83 are fixed with electromagnets 84. The two ends of the side plate 1 are fixed with controllers 85, and the two electromagnets 84 are electrically connected to the two controllers 85 respectively. The electromagnets 84 are energized by the controller 85 to generate magnetic force, which can adsorb the magnetic ring 81 and apply a balancing force to the end of the first roller 3 away from the second roller 5 to offset the downward force due to the weight of the workpiece. As the workpiece assembly moves away from the first roller 3, the controller 85 controls the magnetic force of the electromagnet 84 to gradually decrease, so that the offset of the first roller 3 can always be maintained within a certain range, thereby reducing the vibration of the first roller 3.

[0021] Example 2

[0022] Please refer to Figure 1 As shown, the supporting device 9 includes a second mounting seat 91, a second fixed shaft 92, a bending rod 93, a third fixed shaft 94 and a supporting wheel 95. The second mounting seat 91 is fixed on the upper surface of the base plate 2, and the second fixed shaft 92 is fixed in the middle of the two second mounting seats 91. Bending rods 93 are fixed at both ends of the second fixed shaft 92, and the third fixed shaft 94 is fixed at one end of the bending rod 93 away from the second fixed shaft 92. One end of the third fixed shaft 94 is rotatably connected to a supporting wheel 95 through a bearing, and the supporting wheel 95 is located at the top of the inner wall of the O-ring 7 and contacts. A rubber anti-slip layer is fixed on the outer side of the supporting wheel 95. By arranging the supporting device 9 on the base plate 2, the supporting wheel 95 can always support the O-ring 7, thereby improving the transmission accuracy.

[0023] Example 3

[0024] The O-ring 7 can be a flat belt or a synchronous belt.

[0025] Example 4

[0026] The supporting wheel 95 may be a ring-shaped device with a halo on the surface, such as a ceramic ring.

[0027] Working principle: When in use, the O-ring 7 is sleeved in the groove structure of the pulley 6 for transmission, and the workpiece is transmitted through the two O-rings 7. When the workpiece is transported to the first roller 3 and the second roller 5, due to the effect of gravity, one end of the first roller 3 has a certain amount of displacement downward, which will cause the workpiece transmission to be deflected. When the workpiece passes through a first roller 3, the controller 85 controls the electromagnet 84 to be energized to generate magnetic force, which can adsorb the magnetic ring 81 and apply a balancing force to the end of the first roller 3 away from the second roller 5 to offset the downward force caused by the weight of the workpiece. When the workpiece assembly moves away from the first roller 3, the controller 85 controls the magnetic force of the electromagnet 84 to gradually decrease, so that the offset of the first roller 3 can always be maintained within a certain range, reducing the vibration of the first roller 3. When the workpiece moves from one end to the other end, the load on the first first roller 3 will gradually decrease, and on the contrary, it will gradually increase when it reaches the second first roller 3. At this time, the controller 85 will control the two electromagnets 84 so that the changing loads of the two first rollers 3 can be offset, thereby ensuring that the object is stable during the transmission process, thereby improving the accuracy and stability of the entire transmission system.
