Description

Using the principle of laser ranging, this equipment quickly and non-contactly acquires shade length data, providing reliable assurance of product quality consistency and playing a crucial role in improving production efficiency and reducing defective product rates.

[0003] However, existing laser length measuring equipment has certain defects when measuring the length of the warning light lampshade. At present, the commonly used measurement method is to place the lampshade upright on the test bench, and determine the lampshade length by calculating the difference between the distance from the laser measuring instrument to the test bench and the distance detected by the laser measuring instrument. However, since the top of the lampshade is mostly a hemispherical structure, in order to ensure the accuracy of the measurement data, the laser beam must be accurately irradiated to the center position of the top of the lampshade, which puts extremely high demands on the positioning of the lampshade. However, the existing technology has the problem of insufficient accuracy in the positioning link, and it is difficult to ensure that the lampshade is in the ideal position during each measurement, resulting in large deviations in the measurement data; at the same time, the cumbersome positioning and adjustment process greatly reduces the detection efficiency, increases the production cycle and labor costs, and cannot meet the needs of modern industrial large-scale and efficient production.

Through the synchronous transmission characteristics of the bevel gear set, multiple clamping plates 803 are ensured to move centripetally at the same speed, avoiding the lampshade from deflecting or tilting due to uneven clamping force.

When the first gear 15 rotates, the detection platform 801 is driven to rotate through the ring gear 13, thereby driving the warning light lampshade on the detection platform 801 to rotate. If the lampshade is in a tilted state when clamped, the difference in data changes detected by the laser measuring instrument 7 multiple times is large, thereby judging that the lampshade is in a tilted state, so as to remind the staff to re-test and debug the device to avoid inaccurate positioning caused by device failure affecting the detection accuracy. The threshold can be set for automatic judgment. If the difference exceeds 1mm, an alarm is triggered.

[0026] See also Figures 6 to 10In the embodiment of the present invention, the transmission assembly 9 includes a driving cylinder 901, a nut 902 and a screw 903. The top end of the driving cylinder 901 is fixedly connected to the bottom wall of the second bevel gear 807.

The screw 903 passes through the nut 902 and is threadedly engaged with the nut 902. A ball is provided on the nut 902 to reduce friction. The screw 903 is a ball screw 903. The bottom end of the screw 903 is fixedly installed with a driving seat 904. The driving seat 904 is elastically connected to the connecting seat 808 through an elastic connecting element. A ball 905 is embedded in the bottom of the driving seat 904. The support plate 3 is installed with a The arc-shaped adjustment plate 10 is provided with inclined surfaces 1001 at both ends of the arc-shaped adjustment plate 10. When the rotating table 2 rotates, the rolling ball 905 intermittently contacts the arc-shaped adjustment plate 10; the elastic connecting element includes a connecting tube 906, a connecting column 907 and a spring 908. The top end of the connecting tube 906 is fixedly connected to the connecting seat 808, and the top end of the connecting column 907 extends into the interior of the connecting tube 906, and the connecting column 907 and the connecting tube 906 slide together. The top end of the connecting column 907 is elastically connected to the top wall of the connecting tube 906 through the spring 908, thereby realizing the elastic connection between the driving seat 904 and the connecting seat 808, and limiting the driving seat 904 so that the driving seat 904 can only move up and down, without The arc adjustment plate 10 is located directly below the laser measuring instrument 7. When the ball 905 moves to contact the inclined surface 1001 at the end of the arc adjustment plate 10, as the fixing assembly 8 continues to move, the inclined surface 1001 at the end of the arc adjustment plate 10 pushes the ball 905 to move upward, thereby driving the driving seat 904 to move upward. When the driving seat 904 moves upward, it drives the lead screw 903 to move upward, thereby driving the nut 902 to rotate. When the nut 902 rotates, it drives the driving cylinder 901 to rotate, and then drives the second bevel gear 807 to rotate.

When the warning light lampshade moves out of the detection area, as the rolling ball 905 separates from the arc adjustment plate 10, under the elastic action of the elastic connecting element, the driving seat 904 moves downward and resets, thereby causing the nut 902 to rotate in the opposite direction to drive the second bevel gear 807 to rotate in the opposite direction, and then the multiple vertical plates 802 are reset, so that the lampshade can be removed and placed on the detection table 801 later. When the lampshade moves to the detection area, it can automatically clamp the lampshade to position the lampshade, and automatically release the positioning after the lampshade moves out of the detection area, thereby improving the detection efficiency and having better synchronization.

The lower the height of the arc-shaped adjusting plate 10, the shorter the upward movement of the lead screw 903, and the smaller the movement distance of the vertical plate 802 and the clamping plate 803, so that the movement stroke of the clamping plate 803 can be adjusted, so that it can adapt to lampshades of different sizes, thereby improving the scope of application, and the adjustment method is relatively simple, and the clamping stroke of multiple fixing components 8 can be adjusted with only one adjustment.

[0028] This embodiment realizes the function of automatically driving the clamping plate 803 to clamp and position when the lampshade moves to the detection area, and automatically resetting and loosening after moving out of the detection area through the coordinated arrangement of the arc adjustment plate 10 and the ball 905 in the transmission assembly 9, and the transmission structure of the elastic connecting element and the ball screw 903.
