[0037] The top wall of the installation component 13 and the splash shield 7 is fixedly connected with a square frame 1301, and the square frame 1301 matches with a square groove 1302 reserved inside the sliding plate 3, and the interior of the sliding plate 3 is slidably connected with a plug-in board 1303 through a spring three 1308, and the end of the plug-in board 1303 matches with the plug-in groove 1305 reserved inside the square frame 1301.

When splash shield 2 8 contacts the surface of processing table 4, a closed area of ​​the entire processing device is formed, and the debris generated during the processing is confined in the closed area.

[0039] A light rod 903 is fixedly connected to the inner wall of the sliding groove 902, and the light rod 903 passes through the interior of the sliding block 901 and is connected to the sliding block 901 in an up and down sliding manner.

[0040] The dust suction tube 1001 is in an "L" shape, and the two dust suction tubes 1001 are symmetrically arranged, and the outer wall of the tube body of the dust suction tube 1001 is fixedly mounted with a limit plate 1002, wherein a spring 2 1003 is movably mounted on the outer ring of the dust suction tube 1001, and the two ends of the spring 2 1003 are respectively fixedly connected to the limit plate 1002 and the splash guard 7, and the spring 2 1003 applies pressure to cause the positioning ring 11 and the lower end of the dust suction tube 1001 to always fit the processing table 4.

The inclined surface 1304 is in sliding connection with the upper end of the square frame 1301. The square frame 1301 continuously moves upward to support the inclined surface 1304 and then pushes the plug board 1303 to move until the plug slot 1305 moves to a position flush with the plug board 1303. Then, the elastic force applied by the spring three 1308 pushes the plug board 1303 to match the plug slot 1305, thereby completing the installation of the square frame 1301 and the sliding plate 3.

[0045] The present invention also provides a flexible PCBA processing positioning method, using the above-mentioned flexible PCBA processing positioning device, and the specific operation steps are as follows:

[0046] Step 1: Move the positioning ring 11 upwards and fix the PCBA substrate on the surface of the processing table 4 to facilitate subsequent processing;

[0047] Step 2: The positioning ring 11 is pressed against the surface of the plate to be processed and positioned at the position to be drilled, so that the staff can judge the processing point in advance and ensure that the subsequent processing operation is carried out more smoothly;

[0048] Step 3: The sliding plate 3 descends, driving the splash shield 1 7 and the splash shield 2 8 to descend synchronously. When the splash shield 2 8 contacts the surface of the processing table 4, a closed area of ​​the entire processing device is formed, and the debris generated during the processing is confined in the closed area. At the same time, the dust collection pipe 1001 connected to the external dust collector absorbs and cleans the debris inside the closed area;

[0049] Step 4: Move the two plug-in boards 1303 in the direction of separation, so that the plug-in slots 1305 reserved inside the square frame 1301 are separated, so that the splash guard 1 7 and the splash guard 2 8 are separated from the sliding plate 3, which is convenient for the staff to inspect and repair the cutter head 6.

[0050] Working principle: When using the flexible PCBA processing positioning device and method, first push the positioning ring 11 upward to separate the positioning ring 11 from the surface of the processing table 4, then fix the PCBA substrate to be drilled on the surface of the processing table 4, loosen the positioning ring 11, and under the pressure applied by the spring 904 and the deadweight of the positioning ring 11, the positioning ring 11 is pressed against the surface of the board to be processed and positioned at the position to be drilled, so that the staff can judge the processing point in advance and ensure that the subsequent processing operation is implemented more smoothly;

[0051] The subsequent sliding plate 3 descends, driving the splash shield 1 7 and the splash shield 2 8 to descend synchronously. The splash shield 2 8 first contacts the surface of the processing table 4 during the descent process. At this time, a closed area of ​​the entire processing device is formed. The subsequent sliding plate 3 continues to descend, so that the rotating cutter head 6 contacts the PCBA substrate to be processed and processes the substrate. The debris generated during the processing is confined in the closed area surrounded by the splash shield 1 7 and the splash shield 2 8. At the same time, the dust suction pipe 1001 connected to the external dust collector absorbs and cleans the debris inside the closed area to prevent the debris from splashing and affecting the work of the staff and the cleanliness of the environment;

[0052] When it is necessary to remove the splash guard 1 7 and the splash guard 2 8 for maintenance of the cutter head 6, the two plug-in boards 1303 are moved in the direction of separation, so that the ends of the plug-in boards 1303 are separated from the plug-in slots 1305 reserved inside the square frame 1301, so that the square frame 1301 and the square slots 1302 fall off, thereby facilitating the separation of the splash guard 1 7 and the splash guard 2 8 from the sliding plate 3. When the square frame 1301 is installed later, the square frame 1301 is moved upward to match the square slots 1302, and the upper end of the square frame 1301 is pressed against the The plug-in board 1303 inside the square groove 1302 is provided with an end of an inclined surface 1304. During the continuous upward movement of the square frame 1301, the inclined surface 1304 is supported, thereby displacing and pushing the plug-in board 1303 to move in the direction of the groove 1306. Subsequently, during the continuous upward movement of the square frame 1301, the plug-in slot 1305 moves to a position flush with the plug-in board 1303, and the plug-in board 1303 is pushed to match the plug-in slot 1305 under the action of the elastic force applied by the spring three 1308, thereby completing the installation of the square frame 1301 and the sliding plate 3.

[0053] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
