Description

Technical Field

[0001] The invention relates to a drilling device, in particular to a PP board positioning drilling device. Background Art

[0002] Pure PP board has low density, is easy to weld and process, has excellent chemical resistance, heat resistance and impact resistance, is non-toxic and odorless, and is currently one of the most environmentally friendly engineering PP board plastics. When processing PP board, it is usually necessary to punch it for subsequent use.

[0003] Patent announcement number CN208801443U discloses a plastic plate positioning drilling device, which includes a box body and a pair of conveyor belts with the same structure. The pair of conveyor belts are inserted into the box body, and a drilling structure is installed on the inner upper wall of the box body. A pair of inlet and outlet structures with the same structure are installed on both sides of the conveyor belt, and a pair of clamping structures with the same structure are inserted on the inner front and rear side walls of the box body. When the drilling device is in use, the external power supply of the device is turned on, so that after receiving the command, the first electric push rod in the feeding and discharging structure on one side, the internal direct drive motor drives the telescopic end to extend and push out the clamping cylinder. After the clamping cylinder clamps the plastic plate according to the preset program, the main controller sends a signal to make the rotating cylinder drive the second rodless cylinder to rotate, so as to turn the direction of the plastic plate to face the conveyor belt. The controller sends a signal to control the second rodless cylinder to lift, and then the direct drive motor pushes the telescopic end of the first electric push rod to extend the clamping cylinder at its telescopic end, and then controls the clamping cylinder to release, puts the plastic plate on the conveyor belt, and controls the conveyor belt to start moving until the plastic plate is transported into the box and stops. At this time, according to the preset program, the main controller sends a signal to make the second electric push rods on both sides extend, push the pressure plate to clamp the plastic plate, and after the lead screw transmission receives the signal, the three-phase asynchronous motor inside it drives the lead screw to move laterally along the lead screw, driving the first A rodless cylinder and a drill bit move, and then the first rodless cylinder is controlled to drive the drill bit to move back and forth, so that it reaches the position where the plastic plate needs to be drilled, and the telescopic motor pushes the plastic plate between the pressure plate and the pressure plate to move up, so that the drill bit passes through the plastic plate to drill a hole, and then the telescopic motor is lowered, and the electric push rods on both sides are controlled to lower the plastic plate, and the conveyor belt is started to transport the plastic plate out of the box. After the plastic plate is clamped by the claw cylinder on the other side, the rotating cylinder drives the claw cylinder and the plastic plate on it to turn to the other side, and the controller sends a signal to make the first rodless cylinder lower the claw cylinder and place the plastic plate on the platform, and then control the claw cylinder to release the plastic, and repeat the above operation. The drilling operation can be performed continuously as needed, but the drilling device does not have the function of cleaning the debris generated during the drilling process. If it is not cleaned for a long time or the cleaning is not thorough, it will cause the hole to be deformed or the drilling position to shift when drilling holes in the plastic plate.

[0004] Therefore, it is necessary to design a PP board positioning and drilling device that can suck and collect debris. Summary of the Invention

The inclined plates 1206 are symmetrically and fixedly arranged on the front and back sides of the top of the workbench 2. The mounting block 1205 contacts the inclined plate 1206.

[0034] Please refer to Figures 5-6, the collection mechanism 13 includes a collection box 1301, a first guide rod 1302, a sealing plate 1303, an air outlet pipe 1304, a filter screen 1305, a first collection pipe 1306, a suction box 1307, an exhaust fan 1308, a second collection pipe 1309 and a collection cover 1310. The right part of the fixing frame 6 is symmetrically and fixedly provided with collection boxes 1301 before and after. The collection box 1301 can collect debris. The top of the collection box 1301 is fixedly provided with a first guide rod 1302. A sealing plate 1303 is slidably arranged on the first guide rod 1302. The sealing plate 1303 covers the collection box 1301. The right side of the collection box 1301 is fixedly connected with an air outlet pipe 1304. A filter screen 1305 is fixedly arranged in the air outlet pipe 1304. The filter screen 1305 can prevent debris from floating out.

The bottom of the suction box 1307 is fixedly connected with a second collection pipe 1309. The bottom end of the second collection pipe 1309 is fixedly provided with a collection cover 1310.

[0035] When drilling a hole in the PP board is required, the staff places the PP board on the first sliding seat 4. Under the action of the limiting plate 5, the PP board can be prevented from shifting. After the placement is completed, the staff pushes the first sliding seat 4 to slide to the right. The rightward sliding of the first sliding seat 4 causes the mounting block 1205 to move to the right and disengage from the inclined plate 1206 on the left. The second elastic member 1204 then resets and drives the pressing plate 1203 to move downward. The downward movement of the pressing plate 1203 drives the second sliding rod 1202 to slide downward, and the pressing plate 1203 presses downward to fix the PP board. Since the pressing plate 1203 is made of hard rubber and has a large frictional force, the PP board can be prevented from shifting during the drilling process. Subsequently, the staff continues to push the first sliding seat 4 to slide to the right, so that the position where the PP board needs to be drilled is located below the electric drill bit 9. At this time, the staff starts the cylinder 11, and the telescopic rod of the cylinder 11 extends and squeezes the first sliding rod 7 to slide downward. The first elastic member 10 is then compressed. The downward sliding of the first sliding rod 7 drives the electric drill bit 9 to move downward through the fixing seat 8 and contact the PP board. At this time, the staff starts the electric drill bit 9, and the electric drill bit 9 operates to drill a hole in the PP board, thus realizing the drilling of the PP board. Since a large amount of debris will be generated when the PP board is drilled, the staff can start the air extraction fan 1308. The air extraction fan 1308 operates to suck the debris into the second collection pipe 1309 through the collection cover 1310. The debris in the second collection pipe 1309 then enters the collection box 1301 through the suction box 1307 and the first collection pipe 1306 for centralized collection. The sucked-in air is then discharged through the air outlet pipe 1304. Under the action of the filter screen 1305, the debris can be prevented from floating out. After the drilling of the PP board is completed, the staff turns off the electric drill bit 9 and the air extraction fan 1308 to stop the operation. Then the staff controls the telescopic rod of the cylinder 11 to shorten and no longer squeeze the first sliding rod 7. The first elastic member 10 then resets and drives the electric drill bit 9 to move upward through the fixing seat 8 and disengage from the PP board. After use, the staff turns off the cylinder 11 to stop the operation. Subsequently, the staff continues to push the first sliding seat 4 to slide to the right, so that the mounting block 1205 contacts the inclined plate 1206 on the right. The mounting block 1205 then moves upward and drives the second sliding rod 1202 to slide upward. The second elastic member 1204 is then compressed. The upward sliding of the second sliding rod 1202 drives the pressing plate 1203 to move upward and no longer fix the PP board. The staff removes the PP board from the first sliding seat 4 for collection. After the collection is completed, the staff pushes the first sliding seat 4 to slide to the left to reset. The leftward movement of the first sliding seat 4 causes the mounting block 1205 to disengage from the inclined plate 1206 on the right. The second elastic member 1204 then resets and drives the pressing plate 1203 to move downward. The downward movement of the pressing plate 1203 drives the second sliding rod 1202 to slide downward. When the mounting block 1205 moves to the left and resets and contacts the inclined plate 1206 on the left, the mounting block 1205 then moves upward and drives the second sliding rod 1202 to slide upward and reset. The second elastic member 1204 is then compressed.The second sliding rod 1202 slides upward to drive the pressing plate 1203 to move upward and reset. When it is necessary to clean the debris inside the collection box 1301, the staff pulls the sealing plate 1303 upward to slide and open the collection box 1301. Then, the staff cleans the debris inside the collection box 1301. After the cleaning is completed, the staff pushes the sealing plate 1303 downward to slide and reset to close the collection box 1301.,

[0036] Embodiment 2

[0037] Please refer to Figure 1 and Figure 7 Based on Embodiment 1, it further includes a cleaning mechanism 14. The cleaning mechanism 14 can clean the debris on the PP plate. The cleaning mechanism 14 includes a second fixing block 1401, a second guide rod 1402, a second sliding seat 1403, a third sliding rod 1404, a cleaning brush 1405, and a third elastic member 1406. The second fixing blocks 1401 are symmetrically welded to the front and rear of the left side of the top of the collection cover 1310. A second guide rod 1402 is fixedly arranged between the two second fixing blocks 1401. A second sliding seat 1403 is slidably arranged on the second guide rod 1402. A third sliding rod 1404 is slidably arranged on the second sliding seat 1403. The bottom end of the third sliding rod 1404 is fixedly provided with a cleaning brush 1405. The cleaning brush 1405 can clean the debris on the PP plate. A third elastic member 1406 is connected between the cleaning brush 1405 and the bottom of the second sliding seat 1403. The third elastic member 1406 is sleeved on the third sliding rod 1404.,

[0038] Please refer to Figure 1 、 Figure 8 and Figure 9 It further includes a triggering mechanism 15. The triggering mechanism 15 can make the cleaning brush 1405 move back and forth for cleaning. The triggering mechanism 15 includes a fourth elastic member 1501, a mounting plate 1502, and a top plate 1503. Fourth elastic members 1501 are connected between the second sliding seat 1403 and the inner sides of the two second fixing blocks 1401. The fourth elastic members 1501 are sleeved on the second guide rod 1402. Mounting plates 1502 are symmetrically welded to the front and rear of the top of the second sliding seat 1403. Three top plates 1503 are evenly spaced on the front side of the top of the first sliding seat 4. The same top plates 1503 are symmetrically arranged on the rear side of the top of the first sliding seat 4. When the top plate 1503 moves to the right, it will contact the mounting plate 1502 to make the cleaning brush 1405 move back and forth for cleaning.,

[0039] After the drilling of the PP board is completed, when the staff pushes the first sliding seat 4 to continue sliding to the right, the PP board moves to the right and contacts the cleaning brush 1405. The cleaning brush 1405 slides upward accordingly, the third elastic member 1406 is compressed accordingly, the third sliding rod 1404 slides upward accordingly. The first sliding seat 4 slides to the right and drives the top plate 1503 to move to the right. The front top plate 1503 moves to the right and squeezes the front mounting plate 1502, causing the second sliding seat 1403 to slide backward and drive the cleaning brush 1405 to move backward. The front fourth elastic member 1501 is stretched accordingly, and the rear fourth elastic member 1501 is compressed accordingly. When the front top plate 1503 no longer squeezes the front mounting plate 1502 by moving to the right, the front and rear fourth elastic members 1501 reset accordingly and drive the second sliding seat 1403 to slide forward and reset. The second sliding seat 1403 slides forward and drives the cleaning brush 1405 to move forward. When the rear top plate 1503 moves to the right and squeezes the rear mounting plate 1502, the second sliding seat 1403 is caused to slide forward and drive the cleaning brush 1405 to move forward. The front fourth elastic member 1501 is compressed accordingly, and the rear fourth elastic member 1501 is stretched accordingly. When the rear top plate 1503 no longer squeezes the rear mounting plate 1502 by moving to the right, the front and rear fourth elastic members 1501 reset accordingly and drive the second sliding seat 1403 to slide backward and reset. The second sliding seat 1403 slides backward and drives the cleaning brush 1405 to move backward. Repeating like this, the cleaning brush 1405 is realized to continuously move back and forth to clean the debris remaining on the surface of the drilled PP board. When the PP board moves to the right and disengages from the cleaning brush 1405, the third elastic member 1406 resets accordingly and drives the cleaning brush 1405 to move and reset, and the third sliding rod 1404 slides downward and resets accordingly. When the first sliding seat 4 slides to the left and resets, under the cooperation of the top plate 1503 and the mounting plate 1502, the cleaning brush 1405 moves back and forth again. After the top plate 1503 and the mounting plate 1502 are disengaged, the cleaning brush 1405 stops moving accordingly.

[0040] Please refer to Figure 1 and Figure 10 There is also a moving mechanism 16. The moving mechanism 16 can make the first sliding seat 4 move automatically to the right. The moving mechanism 16 includes a third fixed block 1601, a screw 1602, a slider 1603 and a servo motor 1604. The third fixed block 1601 is welded to the right side of the bottom of the workbench 2. The screw 1602 is rotatably arranged on the third fixed block 1601. The slider 1603 is threadedly arranged on the screw 1602. The slider 1603 is connected to the bottom of the first sliding seat 4. The servo motor 1604 is fixedly arranged on the left side of the bottom of the workbench 2. The output shaft of the servo motor 1604 is connected to the left end of the screw 1602 through a coupling.

[0041] When drilling the PP board is required, the staff starts the servo motor 1604. The output shaft of the servo motor 1604 rotates to drive the screw 1602 to rotate. The rotation of the screw 1602 drives the slider 1603 to move to the right. The rightward movement of the slider 1603 drives the first slide seat 4 to slide to the right. When the PP board moves to the position below the electric drill bit 9, the staff turns off the servo motor 1604 to stop the operation. After the drilling of the PP board is completed, the staff starts the servo motor 1604 again. The slider 1603 continues to move to the right to drive the first slide seat 4 to continue to slide to the right. When the staff has collected the drilled PP board, the staff controls the output shaft of the servo motor 1604 to reverse, driving the screw 1602 to reverse. The reverse rotation of the screw 1602 drives the slider 1603 to move to the left to reset. The leftward movement of the slider 1603 drives the first slide seat 4 to slide to the left to reset. After use, the staff turns off the servo motor 1604 to stop the operation.

[0042] Please refer to Figure 1 and Figure 11 There is also a protection mechanism 17. The protection mechanism 17 can prevent debris from splashing. The protection mechanism 17 includes a fourth fixing block 1701, a fourth sliding rod 1702, a connecting block 1703, a protection cover 1704 and a fifth elastic member 1705. A fourth fixing block 1701 is welded to the right side of the fixing seat 8. A fourth sliding rod 1702 is slidably arranged on the fourth fixing block 1701. A connecting block 1703 is welded to the bottom end of the fourth sliding rod 1702. A protection cover 1704 is fixedly arranged on the left side of the connecting block 1703.
