[0002] Chip resistors generally refer to fixed chip resistors, a type of metal-glass-glaze resistor. They are made by screen-printing a mixture of metal powder and glass-glaze powder onto a substrate. They are resistant to moisture and high temperatures, and have a low temperature coefficient. This significantly reduces circuit space and costs, allowing for more refined designs.

[0003] After the resistor is produced, it will be inspected by a detection device. The commonly used detection method is to use CCD photo detection to screen out defective products. During the detection, the resistors are transported one by one to the bottom of the CCD detection camera through a conveying device for photo detection. However, in the process of conveying the resistors, the positions of some resistors are offset, resulting in incomplete photos of them by the CCD detection camera, affecting the detection results. Therefore, it is necessary to design a detection device for resistors to solve the above problem. Utility Model Content

[0021] Hereinafter, embodiments of a detection device for a resistor sheet according to the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-3 The present invention shows a detection device for resistors according to an embodiment of the present invention, which includes a CCD detection device 2 installed on the top of an operating table 1, a conveyor 3 installed on the top of the operating table 1, and the CCD detection device 2 is arranged on the top of the conveyor 3. The left and right sides of the top of the operating table 1 are rotatably connected with movable guide plate assemblies 4, and the movable guide plate assembly 4 rotates on the top of the conveyor 3. The movable guide plate assembly 4 includes a bottom rod 42 rotatably connected to the inner cavity of the operating table 1. Through the multi-angle rotation setting of the bottom rod 42, the opening and closing size of the two movable guide plate assemblies 4 can be adjusted according to the actual size of the resistor to be detected, so that the detected resistor can be transported in the center of the surface of the conveyor 3. The top of the bottom rod 42 extends to the outside of the operating table 1 and is installed with an L-shaped guide plate 41. The L-shaped guide plate 41 slides up and down in the inner cavity of the bottom rod 42. The bottom of the surface of the bottom rod 42 is fixedly connected with a gear 5. The inner cavity of the operating table 1 slides The gear 5 is meshed with the double-sided toothed plate 6, and the inner cavity of the operating table 1 is rotatably connected with a threaded rod 7, and the double-sided toothed plate 6 is threadedly connected to the surface of the threaded rod 7. The front side of the threaded rod 7 extends to the outside of the operating table 1 and is fixedly installed with a handwheel 8. A guide rail 9 is installed at the bottom of the inner cavity of the operating table 1, and the double-sided toothed plate 6 slides on the top of the guide rail 9. A pulley 10 is installed at the bottom of the double-sided toothed plate 6. The surface of the guide rail 9 is provided with a slide groove 11 for the pulley 10 to move. The inner cavity of the L-shaped guide plate 41 is rotatably connected with multiple rollers 43. Through the setting of the roller 43, when the L-shaped guide plate 41 is used to limit the detection resistor, the resistor will contact the roller 43 and drive the roller 43 to rotate on the surface of the L-shaped guide plate 41, reducing the friction resistance between the resistor and the L-shaped guide plate 41 to avoid scratching the resistor. The L-shaped guide plate 41 is threadedly connected to the inner cavity of the bottom rod 42.

[0023] Working principle: When the present invention is used, the user drives the threaded rod 7 to rotate in the inner cavity of the operating table 1 by turning the hand wheel 8, thereby driving the double-sided tooth plate 6 to slide on the top of the guide rail 9. At this time, the pulley 10 will roll in the inner cavity of the slide groove 11, and then drive the two gears 5 to rotate relative to each other. At this time, the two bottom rods 42 will rotate relative to each other in the inner cavity of the operating table 1, driving the two L-shaped guide plates 41 to rotate, adjusting the opening and closing size of the L-shaped guide plates 41, and limiting the resistance piece transported on the surface of the conveyor 3 through the movable guide plate assembly 4, so that the resistance piece can be transported in the center of the surface of the conveyor 3, thereby ensuring that the CCD detection camera in the CCD detection device 2 takes comprehensive photos and inspections of it. By setting the L-shaped guide plate 41 and the bottom rod 42 to rise and fall, it can adapt to conveyors 3 of different heights, thereby improving the practicality of the device.

[0024] To sum up: the detection device for resistor sheets, by rotating the movable guide plate assembly 4, limits and guides the resistor sheet transported on the surface of the conveyor 3, so that the resistor sheet can be transported in the center of the surface of the conveyor 3, thereby ensuring that the CCD detection camera in the CCD detection device 2 takes pictures and detects it, and adapts to conveyors 3 of different heights by setting the L-shaped guide plate 41 to rise and fall.
