For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0019] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Example 1
[0021] like Figure 1-3 As shown: an automatically moving up and down lampshade for improving the scanning efficiency and accuracy of a camera, comprising a movable trolley 2 slidably mounted on a plotter 1, the trolley 2 being slidably connected to the plotter 1 via a back plate 201, a vertical guide device being arranged on the front end surface of the back plate 201, a camera 5 being arranged at the lower part of the back plate 201, a lampshade 4 being arranged at the outer side of the camera 5, a light source being arranged on the side wall of the lampshade 4, when the plotter 1 program is output, the trolley 2 starts edge scanning, the camera 5 captures the marking points on the paper, a carving knife 205 is slidably arranged on one side of the vertical guide device, the vertical guide device comprises two guide rods 3 arranged on the back plate 201, a right-angle mounting frame 203 is slidably arranged on the guide rods 3, a spring 204 is arranged in the vertical direction between the mounting frame 203 and the back plate 201, the spring 204 assists the mounting frame 203 to move upward, thereby improving the reaction speed.
[0022] A grating sensor 202 is arranged above the mounting frame 203, and the grating sensor 202 is used to detect the position of the engraving knife 205 and provide precise guidance for the operation of the engraving knife 205. The engraving knife 205 is arranged at the lower part of the mounting frame 203, and is used for engraving on the engraving machine. The engraving knife 205 is bolted to the lower part of the mounting frame 203 for contacting with the paper. A first electromagnet 301 is arranged on the upper part of the mounting frame 203, and the moving part of the first electromagnet 301 is fixedly connected to the mounting frame 203 to improve the moving accuracy and stability of the mounting frame 203. The camera 5 is arranged at the bottom of the first electromagnet 301, and the lampshade 4 is moved by the lifting device. The second electromagnet 302 is movably arranged at the lower part of the camera 5, and the lifting device is a second electromagnet 302 arranged on one side of the guide rod 3 on the opposite side of the mounting frame 203. The bottom of the second electromagnet 302 is fixedly connected to the lampshade 4 through a connecting plate, and the connecting plate is slidably arranged on the guide rod 3 through a sleeve. In the process of edge finding, the position of the paper is determined by capturing the two-dimensional code on the paper through the camera 5. When the trolley 2 moves to the specified position, the second electromagnet 302 operates. When the electromagnet is powered on or off, the lampshade 4 can move up and down along the guide rod 3, so as to automatically adjust the height of the lampshade 4 according to the needs of the camera 5 scanning to ensure the best lighting effect. Ensure that the camera 5 can capture clear and accurate image information. At the same time, due to the use of electromagnets as power sources, the device is simple to operate and responds quickly, which greatly improves work efficiency. The design of automatically moving the lampshade 4 up and down not only improves the efficiency and accuracy of the camera 5 scanning, but also reduces the difficulty of operation, which brings great convenience to the use of the engraving machine 1.
[0023] Example 2
[0024] The main difference between this embodiment and embodiment 1 is that the lifting device is an adjustment plate 6 arranged on the outer side of the guide rod 3 on the opposite side of the mounting frame 203, the upper part of the adjustment plate 6 is a hook-shaped hook head bent downward, the upper part of the mounting frame 203 is installed with an upper bearing 2031 abutting against the upper part of the adjustment plate 6, the top of the adjustment plate 6 is hinged to the back plate 201, a tension spring is connected between the lampshade 4 and the back plate 201, a guide hole is horizontally arranged at the lower part of the adjustment plate 6, a roller 601 is arranged on the back plate 201 to pass through the guide hole, the bottom of the adjustment plate 6 is arranged as an inclined surface, the upper part of the lampshade 4 is provided with a lower bearing 602, the lower bearing 602 abuts against the bottom inclined surface of the adjustment plate 6, the inclination angle of the bottom inclined surface of the adjustment plate 6 is 30-60 degrees, and during the edge finding process, the first electromagnet 301 is actuated to drive the mounting frame 203 upward, and the upper bearing 2031 abuts against the adjustment plate 6. The inner side of the hook of the section plate 6 abuts against the lower inclined surface of the adjustment plate 6, thereby driving the lower inclined surface of the adjustment plate 6 to squeeze the lower bearing 602 so that the lampshade 4 moves downward, thereby providing a supplementary light source for the camera 5. After one point is completed, the first electromagnet 301 is reset to the middle position, and the lampshade 4 moves upward under the action of the tension spring, and the action is repeated to complete the edge-finding operation. After the edge-finding operation is completed, the first electromagnet 301 drives the mounting frame 203 and the engraving knife 205 to move downward to perform the engraving operation to complete the production. When the lampshade 4 moves down and presses the paper, it prevents inaccurate positioning due to the paper tilting, and at the same time avoids the ambient light from affecting the camera 5. At this time, the lampshade 4 on the trolley 2 can reduce the area of the lamp irradiation, increase the light intensity, and use the diffuse reflection performance to facilitate the camera 5 to identify the marking points of highly reflective materials, clearly capture and scan, so that the positioning of the trolley 2 is more accurate and the cutting accuracy is higher.
