[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] Example

[0039] like Figures 1-6 As shown, this utility model provides a raw silk image acquisition device, which includes: a four-corner bracket 1, a blackboard silk winding machine 2, a camera 3, and a light source 4;

[0040] The left, right, front and bottom of the four-corner bracket 1 are all hollow. The back of the four-corner bracket 1 is provided with a baffle 5. The bottom of the four-corner bracket 1 is provided with a crossbeam 6. The bottom crossbeam 6 is used to connect and fix the support column 7 of the four-corner bracket 1. The top of the four-corner bracket 1 is provided with a crossbeam 6. The top crossbeam 6 is also used to connect and fix the support column 7 of the four-corner bracket 1.

[0041] The left and right crossbeams 6 at the top of the four-corner bracket 1 are rotatably connected to both ends of the blackboard winding machine 2.

[0042] The camera 3 and the light source 4 together form an image acquisition system, which is fixedly installed at any position above, behind, or below the blackboard winding machine 2.

[0043] The image acquisition system is fixedly installed below the blackboard wire winding machine 2.

[0044] like Figure 1 and Figure 4 As shown, a horizontal support plate 8 is provided between the top beam 6 and the bottom beam 6 of the four-corner bracket 1; a number of square holes 9 are evenly provided in the horizontal support plate 8, and a threaded hole is provided in the center of the square hole 9. The image acquisition system is fixed to the horizontal support plate 8 through the threaded hole.

[0045] Specifically, there are two layout methods. 【1】

[0047] Each support column 7 of the four corner brackets 1 is provided with several limiting grooves, which are used to fix the horizontal support plate 8 at a preset height.

[0048] It is understandable that the limiting grooves on each support column 7 of the four corner brackets 1 are matched with each other, so that the horizontal support plate 8 is on a horizontal plane at a fixed height. 【2】

[0050] Several inclined support brackets 10 are provided on the left and right side beams 6 or the front and rear side beams 6 at the bottom of the four corner brackets 1. Each inclined support bracket 10 includes a pair of support diagonal rods. The inclined support brackets 10 are used to fix the horizontal support plate 8 at a preset height.

[0051] like Figure 5 As shown, Figure 5This is a schematic diagram showing an inclined support bracket 10 for the front and rear crossbeams 6 and a horizontal support plate 8, which is provided from the side.

[0052] Understandably, in extreme cases, only one inclined support bracket 10 is needed to support the horizontal support plate 8. In addition, the inclined support brackets 10 of the left and right side beams 6 or the front and rear side beams 6 can cooperate with each other. For example, the two inclined support brackets 10 of the left and right side beams 6 and the one inclined support bracket 10 of the front and rear side beams 6 can cooperate with each other to support the horizontal support plate 8. Alternatively, only the left and right side beams 6 or only the front and rear side beams 6 can be used.

[0053] The image acquisition system is fixedly installed on the rear side of the blackboard wire winding machine 2.

[0054] like Figure 2 As shown, a plurality of square holes 9 are evenly provided on the upper edge of the inner surface of the baffle of the four corner bracket 1. A threaded hole is provided in the center of the square hole 9. The image acquisition system is fixed to the baffle through the threaded hole. The number of square holes 9 is adapted to the number of the image acquisition system.

[0055] The image acquisition system is fixedly installed above the blackboard wire winding machine 2.

[0056] like Figure 3 As shown, a horizontal support plate 8 is fixedly provided above the blackboard wire winding machine 2. Square holes 9 are evenly provided on the lower surface of the horizontal support plate 8. A threaded hole is provided in the center of the square holes 9. The image acquisition system is fixed to the lower surface of the horizontal support plate 8 through the threaded hole.

[0057] Specifically, each support column 7 of the four corner brackets 1 is connected to the horizontal support plate 8 via a synchronous telescopic rod 11.

[0058] The synchronous telescopic rod 11 can be electric or manual; if it is electric, synchronous control is required; in addition, in order to make the structure more compact, the synchronous telescopic rod 11 can also be embedded in the support column 7, so that when the horizontal support plate 8 is retracted, it can cover the four corner brackets 1.

[0059] Further explanation of each layout method:

[0060] When the image acquisition system is fixedly installed on the rear side of the blackboard wire winding machine 2, the original mechanical structure can be preserved to the greatest extent by fixing the image acquisition system directly on the inner surface of the baffle, without the need for additional devices. However, the rotation center of the blackboard is very close to the side, which places high demands on the parameters of the camera 33 itself, and the image may be distorted. When the blackboard wire winding machine 2 is rotating, the side gap is very small, and the wire is also introduced from the side of the blackboard wire winding machine 2, which may interfere with the normal operation of the blackboard wire winding machine 2.

[0061] When the image acquisition system is fixedly installed above the blackboard wire winding machine 2, the use of a telescopic rod to fix the image acquisition system above the blackboard wire winding machine 2 allows for height adjustment, which is beneficial for image acquisition. However, due to the addition of the telescopic rod, the overall size of the blackboard wire winding machine 2 increases, occupying more space and making it inconvenient to move and store the blackboard wire winding machine 2. Furthermore, due to the presence of the telescopic rod, the operator may be blocked when picking up or placing the blackboard wire winding machine 2, increasing the difficulty of picking up or placing the blackboard wire winding machine 2.

[0062] When the image acquisition system is fixedly installed below the blackboard wire winding machine 2, only an additional horizontal support plate 8 is added, which neither increases the overall size of the blackboard wire winding machine 2 nor interferes with the normal operation of the blackboard wire winding machine 2.

[0063] The entire workflow is explained as follows:

[0064] When the image acquisition system is fixedly installed on the rear side of the blackboard winding machine 2: after the blackboard winding machine 2 stops working and the blackboard is perpendicular to the ground, the image acquisition system is used to take pictures of the raw silk on the blackboard from the inside.

[0065] When the image acquisition system is fixedly set above the blackboard winding machine 2, after the blackboard winding machine 2 stops working and the blackboard is parallel to the ground, the image acquisition system is used to take pictures of the raw silk on the blackboard from top to bottom.

[0066] When the image acquisition system is fixedly set below the blackboard winding machine 2, after the blackboard winding machine 2 stops working and the blackboard is parallel to the ground, the image acquisition system is used to take pictures of the raw silk on the blackboard from bottom to top.

[0067] The remaining parts are explained as follows:

[0068] Light source 4 is a CBW-50034-W strip light source 4, with a light-emitting area size of 500mm×34mm, a length, width and height of 510mm×40mm×20mm, 6 rows of LED beads, a power supply voltage of 24V, a power of 24W, and a color temperature of 6500K.

[0069] All three cameras are CMOS type, with a built-in CMOS 1 / 3.2″ sensor. The dimensions of each camera are 38mm × 38mm × 7.0mm. They have 5 megapixels, a pixel size of 1.4um × 1.4um, an aperture of f / 2.2, a focal length of 3.05mm, a field of view of 90°, a 650 10nm filter, a maximum resolution of 3264*2448, a frame rate of 15fps, a USB power supply voltage of 5V 5%, and an interface speed of 480mb / s.

[0070] like Figure 6 As shown, the length of the blackboard in the blackboard winding machine 2 can be 1359mm and the width can be 469mm. Several raw silk sheets are arranged on the blackboard. There are blank spaces between each raw silk sheet, and the size of the blank spaces between each raw silk sheet is the same. The size of the raw silk sheet can be 125mm×463mm.

[0071] In summary, this utility model provides a raw silk image acquisition device, comprising: a four-corner bracket, a blackboard winding machine, a camera, and a light source; the left, right, front, and bottom of the four-corner bracket are hollowed out, a baffle is provided on the back of the four-corner bracket, and a crossbeam is provided at the bottom of the four-corner bracket for connecting and fixing the support column of the four-corner bracket; a crossbeam is provided at the top of the four-corner bracket for connecting and fixing the support column of the four-corner bracket; the left and right crossbeams at the top of the four-corner bracket are rotatably connected to both ends of the blackboard winding machine; the camera and the light source together form an image acquisition system, which is fixedly installed above, behind, or below the blackboard winding machine. This utility model only includes a four-corner bracket, a blackboard winding machine, a camera, and a light source, and its structure is simple and easy to disassemble and install. In this utility model, by fixing the image acquisition system to the rear side of the blackboard winding machine, no additional equipment is needed, reducing the requirement for necessary equipment. In this utility model, by fixing the image acquisition system above the blackboard winding machine, it will not interfere with the normal operation of the blackboard winding machine. In this invention, by placing the horizontal support plate below the blackboard winding machine, the normal operation of the winding machine is not hindered during inspection, and the overall size of the device is not increased.

[0072] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
