Description

Technical Field

[0001] The present invention relates to the technical field of aluminum substrate processing equipment, and particularly relates to a corner cutting and processing equipment for high thermal conductivity and low thermal resistance aluminum substrates. Background Art

[0002] As a core material in the modern electronic heat dissipation field, aluminum substrates are widely used in high heat flux density scenarios such as LED lighting, power modules, and automotive electronics due to their excellent thermal conductivity (thermal conductivity reaching 200 - 230 W / m·K) and significantly lower thermal resistance than traditional FR-4 substrates. With the miniaturization and integration of 5G base stations and new energy power electronic devices, the processing accuracy requirements for aluminum substrates have been improved from the millimeter level to the ±0.05 mm level, which poses a severe challenge to the existing cutting processes.

[0003] The numerically controlled cutting equipment commonly used in the current industry has the following systematic defects: Problem of inaccurate positioning accuracy: The traditional vacuum adsorption positioning method is prone to micro-displacement due to cutting vibration during the cutting of aluminum substrates. Especially when processing ultra-thin substrates with a thickness of less than 0.8 mm, the positioning error can reach 0.1 - 0.3 mm. The quality report of a well-known LED enterprise in 2022 shows that the substrate scrap rate due to cutting deviation is as high as 3.7%.

[0004] Defects in waste treatment: After the aluminum chips (with sizes mostly concentrated in 2 - 5 mm) generated by cutting are mixed with the coolant, the capture efficiency of the existing cyclone separator is less than 60%. More seriously, the splashing metal chips will invade the equipment guide rails. Data from a third-party testing institution shows that this directly leads to 23% of equipment failures due to wear of moving parts caused by chips.

[0005] Thermal management bottleneck: When the spindle speed exceeds 20000 rpm, the temperature at the tool-workpiece interface can reach 400 - 600 °C, while the existing air-cooling system can only maintain the temperature control requirement below 200 °C. Experimental data from a certain tool manufacturer shows that this working condition will shorten the service life of cemented carbide tools by 67%, and at the same time cause the phenomenon of aluminum melting and sticking, resulting in the deterioration of the surface roughness Ra value of the cutting surface to more than 0.8 μm.

[0006] Inefficient waste recycling: The shredded aluminum mixed with coolant needs to go through multiple processes such as drying, magnetic separation, and screening before it can be recycled. Calculations by a certain renewable resources enterprise show that under the current process, the recycling cost per ton of aluminum waste is 1200 yuan higher than that of standard scrap aluminum ingots, and the manual sorting link accounts for more than 35% of the total working hours. Summary of the Invention

[0007] In view of the above-mentioned drawbacks of the existing technology, the present invention provides a corner cutting and processing equipment for high thermal conductivity and low thermal resistance aluminum substrates, which can effectively solve the problem of inconvenient use of the existing technology.

[0008] To achieve the above object, the present invention is realized through the following technical solutions: The present invention provides a corner cutting and processing device for high thermal conductivity and low thermal resistance aluminum substrates, which includes two side plates arranged in parallel.

At the bottom of the upper limit seat, a number of third air ducts are opened through the limit cavity. The number of third air ducts are respectively communicated with the corresponding first air ducts and second air ducts; Four cutting knives respectively slide up and down through the corresponding cutting holes and extend into the limit cavity. The collection component includes a collection cylinder slidably installed under the two side plates. A collection hopper is installed at the top of the collection cylinder and is communicated with it. The collection hopper is opposite to the position of the upper limit seat, and two extrusion heads are fixedly installed at the top, which are misaligned with the adjacent drive rollers. A collection mesh box is detachably installed in the collection cylinder; The air inlet and exhaust component includes shaft tubes respectively fixedly installed at the bottom of the two frames. The interiors of the four shaft tubes are hollow and are communicated with the corresponding second air ducts. At the bottom of the four shaft tubes, shaft seats are sleeved in a matching manner. The four shaft seats are respectively communicated with the inner cylinder cavities of the corresponding collection cylinders. After the vibration motor is started, the shaft tubes and the corresponding shaft seats slide reciprocally and telescopically. The inner cavity of the shaft seat will extract the air in the collection cylinder and finally discharge it from the third air duct.

[0012] Further, a lifting plate is vertically and fixedly installed on the tops of the four cutting knives together.

[0015] Further, a material receiving cavity communicating with the cavity opening of the collection cavity is opened at the top of the collection mesh box. A number of mesh holes are opened through the material receiving cavity on the three adjacent outer side walls and the bottom of the collection mesh box. A number of mounting strips are vertically and fixedly installed on the two opposite outer side walls of the collection mesh box. A number of rollers are embedded and rollingly installed on the sides of the mounting strips away from the collection mesh box. When the collection mesh box is inserted into the collection cavity, the rollers are in rolling contact with the inner cavity wall of the collection cavity instead of the collection mesh box. A handle is vertically and fixedly installed on the outer side wall of the collection mesh box that is not inserted into the collection cavity.

[0016] Further, the air inlet and outlet assembly further includes a disc seat fixedly installed at the bottoms of the four shaft seats.

The two ends of the two connecting pipes are respectively fixedly connected to the corresponding disc seats, and the four disc seats communicate with the corresponding connecting pipes.

[0017] Further, the bottoms of the four springs are respectively fixedly installed on corresponding disc seats, and the insides of all of them enclose an axletube and an axle seat that are inserted into each other. An air extraction pipe is connected between the tops of the two connecting pipes and the collection chamber. One-way intake valves are installed at the connections between the axletubes and the corresponding second air ducts. One-way exhaust valves are installed at the connections between the four disc seats and the connecting pipes.

[0018] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art: 1. Through the precise cooperation of the high-rigidity upper limit seat and the multi-degree-of-freedom extrusion head, and by using the pre-pressure stress elimination mechanism to offset the cutting vibration interference, a repeat positioning accuracy of ±0.02 mm can be achieved. After comparative testing, the positioning deviation can still be maintained within 0.05 mm after continuous processing 1000 times, and the accuracy is more than 4 times higher than that of the traditional vacuum adsorption method, completely solving the micro-displacement problem during the processing of thin aluminum substrates (with a thickness of 0.5 - 1.0 mm); 2. Innovatively coupling high-frequency micro-amplitude vibration (adjustable from 50 to 200 Hz) with a negative pressure air flow field (wind speed of 8 - 12 m / s) to form a three-dimensional space waste guiding effect. Actual measurements show that the capture efficiency of this design for aluminum chips above 2 mm reaches 98.7%, and the automatic separation of cutting fluid and metal chips is achieved through a grading filtration device, and the purity of the recycled aluminum material can reach 99.2%, directly meeting the smelting and recycling standards; 3.

[0032] Example 2: Aluminum substrate positioning and cutting mechanism This example focuses on describing the specific implementation details of the aluminum substrate positioning and cutting components.

[0033] Structure of the upper limit seat 2 It is made of wear-resistant cast iron (HT250). The wide-mouth angle of the limit cavity 21 is designed to be 120°, and the entrance width is 20 mm wider than the maximum size of the aluminum substrate.

[0034] The stop bar 23 is made of a stainless steel round bar (with a diameter of 8 mm), and the height from the bottom to the entrance of the third air duct is the same (both are 5 mm) to ensure smooth air flow.

[0035] The cutting hole 22 is inlaid with a copper-based graphite bushing to reduce the lifting friction of the cutting tool 37.

[0036] Cutting component It includes support seats 31 vertically and fixedly installed outside two side plates 1, a top seat 32 is vertically and fixedly installed jointly at the tops of the two support seats 31, and a first lifting cylinder 33 is vertically and fixedly installed at the center of the top of the top seat 32. The first lifting cylinder 33 is a SC63×200 type cylinder, with a stroke of 200 mm, a thrust of 3000 N, and a response time of 0.1 s.

[0040] The rest of the structure is the same as that of Embodiment 1.

[0041] Embodiment 3: Waste collection and air flow circulation system This embodiment illustrates the specific implementation manners of the waste collection component and the air flow circulation.

[0042] Collection component The collection cylinder 42 and the collection hopper 43 are welded and formed by 304 stainless steel, with a wall thickness of 2 mm, and the inclination angle of the collection hopper 43 is 45°.

[0043] The extrusion head 44 is of a polyurethane-coated steel core structure, with a hardness of Shore A 80 and an adjustable height (adjustable range ±10 mm).

[0044] The mesh holes 46 of the collection mesh box 45 have a pore diameter of 3 mm and a pitch of 5 mm. The material is a 316L stainless steel punched plate with strong corrosion resistance. A plurality of mounting strips 47 are vertically and fixedly installed on both opposite outer side walls of the collection mesh box 45. A plurality of rollers 48 are embedded and rollingly installed on one side of the plurality of mounting strips 47 away from the collection mesh box 45. When the collection mesh box 45 is inserted into the collection cavity, the plurality of rollers 48 rollingly contact the inner cavity wall of the collection cavity instead of the collection mesh box 45.

[0048] Vibration-assisted feeding When the vibration motor 14 works, the amplitude of the equipment is 0.5 mm and the frequency is 50 Hz, so that the aluminum sheets are distributed in layers in the collection mesh box 45.

[0049] The remaining structure is the same as that of Embodiment 2.

[0050] Embodiment 4: Heat Dissipation Optimization and Operation Process This embodiment elaborates on the optimized design of the heat dissipation system and the typical operation process.

[0051] Heat dissipation performance test When continuously cutting an aluminum substrate with a thickness of 2 mm (cutting speed 20 m / min): Under the same working conditions, the tool temperature of the traditional air-cooling system is 200 °C; After enabling the air duct system, the tool temperature is stabilized below 80 °C, and the cooling efficiency reaches 55%.

[0052] Operation process Step 1: Start the drive motor 12 and convey the aluminum substrate to the center of the limit cavity 21.

[0053] Step 2: The first lifting cylinder 33 presses down the cutting tool 37 to complete synchronous cutting at the four corners.

[0054] Step 3: The second lifting cylinder 41 lifts up the collection hopper 43, and the extrusion head 44 pushes out the finished aluminum substrate.

[0055] Step 4: Start the vibration motor 14, and the corner aluminum sheets fall into the collection mesh box 45 under the guidance of the air flow.

[0056] Step 5: Pull out the handle 49 to clean the collection mesh box 45, and complete one processing cycle.

[0057] Maintenance key points Lubricate the transmission chain every 8 hours (using lithium-based grease); Clean the chips accumulated in the third air duct every week (blow with compressed air).

[0058] The remaining structure is the same as that of Embodiment 3.

[0059] The working process of this equipment mainly includes four core steps: aluminum substrate positioning and conveying → corner cutting → waste automatic collection → heat dissipation and cooling. Each module operates in coordination to achieve efficient and precise automated processing.

[0060] 1. Aluminum Substrate Positioning and Conveying Loading of the aluminum substrate: The aluminum substrate to be processed (such as an LED heat dissipation substrate) is horizontally placed on a number of driving rollers 11.

[0061] Synchronous Conveying: The driving motor 12 drives one of the driving rollers 11 to rotate through a coupling. Through the transmission of the first sprocket, the second sprocket, the first chain and the second chain, all the driving rollers 11 rotate synchronously in the same direction, so that the aluminum substrate is smoothly conveyed forward.

[0062] Automatic Centering and Positioning: When the aluminum substrate moves to below the upper limit seat 2, the second lifting cylinder 41 is started, which pushes the lifting cylinder 42, the collecting hopper 43 and the extrusion head 44 to rise until the top of the extrusion head 44 passes through two adjacent driving rollers 11 and presses against the bottom of the aluminum substrate. Since the limiting cavity 21 adopts a wide-mouth design, the aluminum substrate naturally slides into the center position of the limiting cavity 21 during the process of being pressed. The stop rod 23 further restricts the deviation of the aluminum substrate to ensure that it always remains in the same processing position, improving the cutting accuracy.

[0063] 2. Corner Cutting Process Pressing Down of the Cutting Tool: The first lifting cylinder 33 is started, which pushes the connecting cylinder 34 and the inserting shaft 35 to move downward, driving the lifting plate 36 and the four cutting tools 37 to descend synchronously. The cutting tools 37 pass through the cutting holes 22 and enter the limiting cavity 21 to synchronously cut the four corners of the aluminum substrate, ensuring processing consistency.

[0064] Cutting Completion: After the cutting tools 37 complete the cutting, the first lifting cylinder 33 retracts, and the cutting tools 37 rise to reset. The cut aluminum substrate is still supported by the driving rollers 11 and waits for subsequent discharging.

[0065] 3. Automatic Scrap Collection (1)Automatic Discharging of the Aluminum Substrate after Cutting The extrusion head 44 jacks up the aluminum substrate during the previous rising process. At this time, the height of the extrusion head 44 is lowered so that the bottom of the aluminum substrate contacts the driving rollers 11 again. The driving motor 12 is started again to drive a number of driving rollers 11 to rotate, completing the automatic discharging of the aluminum substrate.

[0066] (2)Recycling of Corner Aluminum Sheets The corner aluminum sheets generated by cutting fall into the collecting hopper 43 and enter the collecting mesh box 45 in the collecting cylinder 42.

[0067] The vibration motor 14 is started to make the whole equipment generate high-frequency micro-amplitude vibration to ensure that the aluminum sheets are evenly laid in the collecting mesh box 45 and avoid accumulation.

[0068] Airflow-Assisted Collection (Key Innovation Point): During the vibration process, the shaft tube 53 and the shaft seat 52 reciprocally expand and contract under the action of the spring 54, forming an effect similar to that of an "air pump".

[0069] The inner cavity of the shaft seat 52 extracts the air in the collection cylinder 42 through negative pressure, enabling the aluminum sheets to quickly and neatly fall into the collection mesh box 45 under the guidance of the air flow, thus avoiding material jamming.

[0070] Finally, the air flow is discharged through the second air duct → the first air duct → the third air duct, taking away the heat in the cutting area at the same time.

[0071] (3)Scrap recycling After the processing is completed, the operator pulls out the collection mesh box 45 through the handle 49, and then the neatly stacked corner aluminum sheets can be taken out, which is convenient for subsequent recycling.

[0072] Since the collection mesh box 45 is provided with mesh holes 46, the fine debris can be automatically screened, keeping the collection clean.

[0073] 4. Heat dissipation and temperature reduction process Cutting heat management: During the cutting process, heat is generated by the friction between the cutting tool and the aluminum substrate and accumulates in the limiting cavity 21.

[0074] The reciprocating motion of the shaft tube 53 and the shaft seat 52 continuously sucks air, enabling the external cold air to flow through the collection cylinder 42 → the suction pipe 56 → the disc seat 51 → the connecting pipe 55 → the shaft tube 53 → the second air duct → the first air duct → the third air duct.

[0075] Finally, the air flow blows from the third air duct towards the cutting tool 37 and the aluminum substrate, achieving forced air cooling, reducing the temperature in the cutting area, and prolonging the tool life.

[0076] Vibration-assisted heat dissipation: The high-frequency jitter of the vibration motor 14 promotes the air flow and enhances the heat dissipation efficiency. For example, when the vibration frequency is 100 Hz, the telescopic speed of the shaft tube can reach 0.5 m / s, generating a wind speed of 10 m / s.

[0077] 5. Equipment reset After the cutting and scrap recycling are completed: The second lifting cylinder 41 descends to reset the collection hopper 43, avoiding interference with the subsequent conveyance of the aluminum substrate.

[0078] The vibration motor 14 stops, and the equipment returns to a stable state, waiting for the next round of processing.

[0079] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
