[0011] Furthermore, the waste collection device includes a flexible rod, the end of which is fixedly connected to the inner wall of a protective box.

[0013] The present invention has the following beneficial effects: When the motor of this invention is turned on, the output end drives the threaded rod to rotate. When the threaded rod rotates, it drives the clamping plate to move via the moving plate. The clamping plate moves inside the moving groove via the support slide rod, making the movement of the clamping plate more stable. The movement of the clamping plate allows the machine to clamp circuit boards of different sizes. At the same time, when the clamping plate clamps the circuit board, it squeezes the elastic rod to avoid excessive compression that could cause bending damage to the circuit board. When the machine drills holes in the circuit board, it squeezes the pulley to squeeze the shock-absorbing pad, which relieves the force and prevents the circuit board from bending in the middle due to excessive compression during the drilling process, affecting normal use. When the clamping plate moves, it drives the shock-absorbing rod and the support plate to move together. The support plate supports both ends of the circuit board, and the shock-absorbing rod buffers the circuit board when the machine drills holes, preventing excessive compression that could affect the quality of the finished product.

[0014] When the second motor is turned on, its output end drives the second threaded rod to rotate. The rotation of the second threaded rod drives the slide rail to move within the guide groove via the guide pulley. The fixed telescopic rod makes the movement of the guide pulley more stable, preventing positional deviations that could affect the precise drilling of the circuit board. Simultaneously, as the slide rail moves, it drives the cutting head device and the grinding head to move together, allowing the machine to adjust to the required drilling position on the circuit board. The servo unidirectional electric actuator, when its output end is turned on, drives the lifting slider and the lifting slide plate to move together within the slide rail. This allows the machine to adjust the position of the cutting head device according to the circuit board thickness, thus enabling drilling operations on circuit boards of different thicknesses. When the third motor is turned on, its output end drives the third threaded rod to rotate via a rotating rod. The rotation of the third threaded rod, when it rotates, drives the cutting head device and the grinding head to move via a moving support plate, allowing the machine to drill circuit boards of different sizes. This also makes the drilling position more precise. The grinding head polishes the inner wall of the hole after drilling, making the inner wall smoother and preventing burrs from affecting the normal use of the circuit board. The tension rod makes the movement of the moving support plate more stable.

[0015] When the movable support plate moves, the support ring plate drives the suction head to pull the hose, ensuring that the suction head and the cutter head are always in the same position. The flexible rod and the reset plate limit and reset the hose, preventing it from getting tangled due to excessive stretching, which would affect the cleaning of waste. When the air pump is turned on, the output end will draw the waste generated during the machine's drilling through the suction port, sucking it into the waste collection box for centralized collection. This prevents waste accumulation from affecting the machine's precise drilling of circuit boards and thus impacting the quality of the finished product. When the support slide bar moves, the support block drives the push plate to move together. When the push plate comes into contact with the extrusion plate, it rotates upward on the surface of the support block due to the extrusion. As the push plate moves towards the cleaning door, the curved baffle blocks the push plate, causing it to push the waste along with it towards the cleaning door. At the same time, the push plate squeezes the extrusion plate, causing it to rotate on the surface of the rotating rod, thus driving the waste through quickly. When the push plate and the extrusion plate separate, the elasticity of the curved spring rod causes the extrusion plate to reset, causing the extrusion plate to repeatedly block the push plate. The push plate pushes the waste towards the cleaning door, making the machine easier to clean.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The waste collection device 6 includes a flexible rod 61. The flexible rod 61 and the reset plate 63 limit and reset the flexible hose 62. The end of the flexible rod 61 is fixedly connected to the inner wall of the protective box 1. The inner wall of the waste collection box 29 has a cleaning door 60. The flexible hose 62 is fixedly connected to the inner wall of the waste collection box 29. The reset plate 63 is fixedly connected to the surface of the flexible hose 62.

When the push plate 70 contacts the squeezing plate 68, it will rotate upward on the surface of the support block 66 due to squeezing. Through the squeezing plate 68, when the push plate 70 moves towards the cleaning door 60, it will be blocked by the curved baffle 71, causing the push plate 70 to push the waste together towards the cleaning door 60. At the same time, the push plate 70 The extrusion plate 68 is squeezed, causing it to rotate on the surface of the rotating rod 67, thus driving the waste debris through quickly.

[0029] When in use, the output end of motor 20 drives the threaded rod 21 to rotate. The rotation of the threaded rod 21 drives the clamping plate 27 to move via the moving plate 32. The clamping plate 27 moves within the moving groove 30 via the support slide rod 31, making its movement more stable. The movement of the clamping plate 27 allows the machine to clamp circuit boards of different sizes. Simultaneously, when clamping the circuit board, the clamping plate 27 compresses the elastic rod 26, preventing excessive compression that could cause bending damage. When the machine drills holes in the circuit board, the compression causes the pulley 23 to press against the shock-absorbing pad 24, relieving pressure and preventing the circuit board from bending due to excessive compression during drilling, thus affecting normal use. The movement of the clamping plate 27 also drives the shock-absorbing rod 33 and the support... The support plate 34 moves together with the circuit board, and the support plate 34 supports both ends of the circuit board. The shock absorber 33 buffers the circuit board when the machine is drilling, avoiding excessive pressure that could affect the quality of the finished product. When the second motor 40 is turned on, its output end drives the second threaded rod 41 to rotate. When the second threaded rod 41 rotates, it drives the slide rail 45 to move inside the guide groove 42 through the guide pulley 44. The fixed telescopic rod 43 makes the guide pulley 44 more stable when it moves, avoiding positional deviation that could affect the precise drilling of the circuit board. At the same time, when the slide rail 45 moves, it drives the cutter head device 54 and the grinding head 55 to move together, allowing the machine to be adjusted according to the required drilling position of the circuit board. When the servo unidirectional electric push rod 46 is turned on, its output end drives the lifting slider 47 and the lifting slide plate 48 to move together. The internal components of rail 45 move together, allowing the machine to adjust the position of the cutter head device 54 according to the different thicknesses of the circuit boards, thus enabling drilling operations on circuit boards of varying thicknesses. When the third motor 49 is turned on, its output end drives the third threaded rod 51 to rotate via the rotating rod 50. The rotation of the third threaded rod 51, in turn, drives the cutter head device 54 and the grinding head 55 to move via the moving support plate 53, allowing the machine to drill circuit boards of different sizes and ensuring more precise drilling. The grinding head 55 polishes the inner wall of the drilled hole, making it smoother and preventing burrs from affecting the normal use of the circuit board. The tension rod 52 makes the moving support plate 53 more stable during movement. The moving support plate 53 moves via the support ring plate 6. 5. The suction head 64 pulls the hose 62, ensuring that the suction head 64 and the cutter head device 54 are always in the same position. The flexible rod 61 and the reset plate 63 limit and reset the hose 62, preventing it from getting tangled due to excessive stretching, which would affect the cleaning of waste. When the air pump 75 is turned on, the output end will draw the waste generated during the machine's drilling through the suction port 72, allowing the suction head 64 to suck the waste generated during drilling into the waste collection box 29 for centralized collection. This prevents waste accumulation from affecting the machine's precise drilling of the circuit board, thus affecting the quality of the finished product. When the support slide bar 31 moves, it drives the push plate 70 to move together through the support block 66. When the push plate 70 contacts the extrusion plate 68, it will rotate upward on the surface of the support block 66 due to extrusion, and then rotate upward through the extrusion plate 68.When the push plate 70 moves towards the cleaning door 60, the curved baffle 71 obstructs it, causing the push plate 70 to push the waste along with it towards the cleaning door 60. Simultaneously, the push plate 70 compresses the squeezing plate 68, causing it to rotate on the surface of the rotating rod 67, thus propelling the waste through quickly. When the push plate 70 separates from the squeezing plate 68, the spring force of the curved spring rod 69 causes the squeezing plate 68 to reset, repeatedly obstructing the push plate 70. The push plate 70 then pushes the waste towards the cleaning door 60, making cleaning easier.
