Description

Technical Field

[0001] This utility model relates to the field of aluminum substrate processing technology, and specifically to a drilling dust removal mechanism for aluminum substrate processing. Background Technology

[0002] Aluminum substrate is a type of copper-clad laminate with excellent heat dissipation. It typically consists of three layers: a circuit layer (copper foil), an insulating layer, and a metal substrate. For high-end applications, it is also designed as a double-sided or multi-layer board, with the structure consisting of a circuit layer, an insulating layer, an aluminum substrate, another insulating layer, and another circuit layer. The working principle of aluminum substrate is based on its good thermal conductivity, which can effectively conduct heat from the circuit layer to the metal substrate, thereby reducing the product's operating temperature and improving its power density and reliability. In addition, aluminum substrate also has excellent electrical insulation and machinability, making it suitable for various high-power, high-frequency electronic applications, such as LED lighting, audio equipment, power supply equipment, and automotive electronics. Drilling is required during the processing of aluminum substrate.

[0003] Because drilling generates dust and debris, which are light and float in the surrounding air, workers can inhale them into their lungs, which can affect their health over time. Therefore, we provide a dust removal mechanism for drilling aluminum substrates. Utility Model Content

[0004] The purpose of this invention is to provide a drilling dust removal mechanism for aluminum substrate processing, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A drilling dust removal mechanism for aluminum substrate processing includes a support plate, a hydraulic cylinder is fixedly installed at the top center of the support plate, a piston rod is provided at the extended end of the hydraulic cylinder, and an extension column is fixedly installed at the other end of the piston rod.

[0007] Dust-collecting units are provided on both sides of the top of the bearing plate, and dust-proof units are provided on the outer surface of the extension column.

[0008] The dustproof unit includes a dustproof cover that is slidably sleeved on the outer surface of the bottom end of the extension column. The bottom end of the dustproof cover is provided with a rubber ring, so that it will not damage the aluminum substrate when it is attached.

[0009] A further improvement of this utility model is that: a limiting groove is provided on all four sides of the inner wall of the dust cover, a return spring is fixedly installed on all four sides of the top of the dust cover, a fixing arc block is fixedly installed on the other end of the return spring, and the fixing arc block is fixedly installed at the top of the outer surface of the extension column. The limiting groove can limit the position of the dust cover on the outer surface of the extension column.

[0010] A further improvement of this utility model is that a drill bit is fixedly installed at the middle position of the bottom end of the extension column, and sliders are fixedly installed on all four sides of the bottom end of the outer surface of the extension column, and the sliders are slidably installed inside the limiting groove.

[0011] A further improvement of this utility model is that: a dust suction chamber is provided on both sides of the bottom end of the extension column, and the dust suction chamber extends on both sides of the top end of the extension column.

[0012] A further improvement of the present invention is that the dust collection unit includes a dust collection box fixedly installed on both sides of the top of the support plate, and a dust collection pump is fixedly installed on the left side of the dust collection box.

[0013] A further improvement of this utility model is that a vacuum hose is fixedly installed on the right input port of the dust collection box, and the other end of the vacuum hose passes through the support plate and is fixedly installed at the top of the vacuum chamber.

[0014] A further improvement of this utility model is that: the top of the dust collection box is provided with an installation groove, and a filter screen plate is movably inserted into the installation groove. The top of the filter screen plate is provided with a snap-fit ​​groove. The filter screen plate can filter the debris sucked into the dust collection box and prevent it from entering the dust pump.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a drilling dust removal mechanism for aluminum substrate processing. By setting a dust cover to follow the extension column downwards, it first contacts the aluminum substrate and continues to move downwards, causing it to be squeezed and slide on the outer surface of the extension column and move upwards, squeezing the return spring until the drill bit contacts the aluminum substrate to drill. Under the elastic counter-push force of the return spring, the bottom end of the dust cover is always attached to the top of the aluminum substrate and located around the drill bit, which can cover the dust generated during drilling inside and prevent it from drifting to the outside, thereby improving the quality of the surrounding environment.

[0017] 2. This utility model provides a drilling dust removal mechanism for aluminum substrate processing. By setting up a dust pump to generate suction, a negative pressure is formed inside the dust collection box. In conjunction with the dust suction hose and dust suction chamber, the dust gathered by the dust cover is sucked into the dust collection box, which facilitates unified processing later and further improves work efficiency.

[0025] Example 1

[0026] like Figure 1-5As shown, this utility model provides a drilling dust removal mechanism for aluminum substrate processing, including a support plate 1. A hydraulic cylinder 2 is fixedly installed at the top center of the support plate 1. A piston rod 3 is provided at the extended end of the hydraulic cylinder 2. An extension column 4 is fixedly installed at the other end of the piston rod 3. Dust collection units are provided on both sides of the top of the support plate 1. A dustproof unit is provided on the outer surface of the extension column 4. The dustproof unit includes a dustproof cover 42 that is slidably sleeved on the outer surface of the bottom end of the extension column 4. Limiting grooves 4 are formed on all four sides of the inner wall of the dustproof cover 42. 3. A return spring 44 is fixedly installed on all four sides of the top of the dust cover 42. A fixed arc block 45 is fixedly installed on the other end of the return spring 44. The fixed arc block 45 is fixedly installed at the top of the outer surface of the extension column 4. A drill bit 41 is fixedly installed at the middle position of the bottom end of the extension column 4. A slider 46 is fixedly installed on all four sides of the bottom end of the outer surface of the extension column 4. The slider 46 is slidably installed inside the limiting groove 43. A dust suction chamber 47 is opened on both sides of the bottom end of the extension column 4. The dust suction chamber 47 extends on both sides of the top end of the extension column 4.

[0027] Furthermore, the dust cover 42 moves downwards following the extension column 4, first contacting the aluminum substrate, and continuously moving downwards to be squeezed and slide on the outer surface of the extension column 4, moving upwards and squeezing the return spring 44 until the drill bit 41 contacts the aluminum substrate to drill a hole. Under the elastic counter-push force of the return spring 44, the bottom end of the dust cover 42 is always attached to the top of the aluminum substrate around the drill bit 41, which can cover the powder generated during drilling inside and prevent it from drifting to the outside.

[0028] Example 2

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the dust collection unit includes a dust collection box 48 fixedly installed on both sides of the top of the support plate 1. A dust collection pump 49 is fixedly installed on the left side of the dust collection box 48, and a dust collection hose 410 is fixedly installed on the right input port of the dust collection box 48. The other end of the dust collection hose 410 passes through the support plate 1 and is fixedly installed at the top of the dust collection chamber 47. An installation groove 411 is provided on the top of the dust collection box 48. A filter screen plate 412 is movably inserted into the installation groove 411. A snap-fit ​​groove 413 is provided on the top of the filter screen plate 412.

[0030] Furthermore, the dust pump 49 is turned on, and the suction generated by the dust pump 49 creates a negative pressure inside the dust collection box 48. In conjunction with the dust suction hose 410 and the dust suction chamber 47, the dust gathered by the dust cover 42 is sucked into the dust collection box 48 for easy processing later.

[0031] The working principle of the drilling and dust removal mechanism for aluminum substrate processing will be explained in detail below.

[0032] like Figure 1-5 As shown, during use, the activation of the hydraulic cylinder 2 causes its extension end to drive the piston rod 3 downward, pushing the extension column 4 and the drill bit 41 closer to the aluminum substrate for drilling. As it moves downward, the dust cover 42 first contacts the aluminum substrate. As it continues to move downward, the dust cover 42 is squeezed and slides on the outer surface of the extension column 4, moving upward and squeezing the return spring 44 until the drill bit 41 contacts the aluminum substrate for drilling. Under the elastic counter-force of the return spring 44, the bottom end of the dust cover 42 is always attached to the top of the aluminum substrate around the drill bit 41, which can cover the dust generated during drilling inside and prevent it from drifting to the outside. At the same time, the dust pump 49 is turned on, and the suction force generated by the dust pump 49 creates a negative pressure inside the dust collection box 48. With the help of the suction hose 410 and the suction chamber 47, the dust gathered by the dust cover 42 is sucked into the dust collection box 48 for later unified processing.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
