Description

Technical Field

[0001] The invention relates to the technical field of automatic processing, and in particular to a heat sink processing device that can be intelligently controlled. Background Art

[0002] Heat sinks are generally produced by milling a number of through grooves on an aluminum alloy block using milling equipment, thereby forming a number of heat sink fins on the surface of the workpiece. However, a large amount of debris is generated during the milling process, and the flying debris can cause the working environment to become dirty.

[0003] In addition, after the existing milling equipment processes the heat sink, burrs will remain on the milled surface. In order to ensure the processing quality, subsequent processes are often required to remove the burrs, which invisibly increases the work cost and the processing efficiency cannot be guaranteed. Summary of the invention

[0004] The purpose of the present invention is to provide a heat sink processing device that can be intelligently controlled to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: the heat sink processing equipment includes a bed, a multi-axis module, a milling mechanism, a control system and a tool changing mechanism. The multi-axis module is slidably connected to the bed, the milling mechanism is firmly connected to the multi-axis module, the control system is electrically connected to the multi-axis module, the milling mechanism and the tool changing mechanism, the control system is used to control the movement of the multi-axis module, the tool changing mechanism is firmly connected to the bed, and the milling mechanism is used to remove burrs while milling the workpiece.

[0006] The present invention processes the heat sink by milling. The bed is installed on the ground to provide a stable working environment for processing. During processing, the workpiece to be processed is first placed on the bed for fixing, and then a set milling program is input into the control system. The control system can automatically control the multi-axis module to move along a set trajectory, thereby driving the milling mechanism to move above the workpiece, and then milling the required heat sink shape on the workpiece, thereby realizing intelligent regulation of the processing process. The tool changing mechanism is a prior art and will not be described in detail here. The tool changing mechanism can automatically change the tool under the control of the control system, thereby improving the intelligence of the processing process. In order to ensure the flatness of the workpiece surface after processing, a corresponding mechanism is integrated on the milling mechanism to remove burrs generated during the milling process.

[0007] Furthermore, an installation cabinet is provided on one side of the bed, and a dust collection chamber and an air compressor are provided in the installation cabinet. The milling mechanism includes a milling component, a chip removal component, a deburring component and a rotating component. The milling component is tightly connected to the multi-axis module, the chip removal component is tightly connected to the milling component, the chip removal component is connected to the dust collection chamber and the air compressor, the deburring component is tightly connected to the chip removal component, the rotating component is tightly connected to the chip removal component, and the rotating component is used to adjust the position of the deburring component.

[0008] The milling assembly is connected to the multi-axis module, so that it can move freely on the surface of the workpiece. However, a large amount of debris will be generated during the milling process. In order to prevent the debris from splashing, a chip removal assembly is set to collect the splashed debris and introduce it into the dust collecting chamber in the installation cabinet for collection; in addition, in order to improve the efficiency of collecting debris, an air compressor is used to provide high-speed airflow to the chip removal assembly, and the movement trajectory of the debris is constrained by the high-speed airflow; since the heat sink is made by milling a number of through grooves on a whole piece of aluminum alloy workpiece, and the deburring assembly is arranged on both sides of the milling assembly, in order to ensure that the deburring assembly can be smoothly inserted into the milled through groove on the workpiece, the movement of the rotating assembly is controlled by the control system so that the position of the deburring assembly is the same as the milling direction.

[0009] Furthermore, the milling assembly includes a fixed shaft, a power shaft and a milling cutter, the fixed shaft is tightly connected to the multi-axis module, the power shaft is rotationally connected to the fixed shaft, and the milling cutter is transmission-connected to the power shaft.

[0010] The fixed axis is used to connect the multi-axis module, and the power axis is used to output torque, thereby driving the milling cutter to rotate at a certain speed to perform milling processing on the workpiece.

[0011] Furthermore, the chip removal assembly includes a fixed ring, a rotating cover, an air supply hose, a guide ring and an air distribution pipe. The fixed ring is tightly connected to the fixed shaft, the rotating cover is rotatably connected to the fixed ring, a chip removal port is provided on the rotating cover, and the chip removal port is connected to the dust collecting chamber. The guide ring is tightly connected to the bottom of the rotating cover, one end of the air supply hose is connected to the air compressor, and the other end of the air supply hose is connected to the guide ring. The air distribution pipe is connected to the inner cavity of the guide ring. The air distribution pipe is circumferentially arranged on the inner wall of the rotating cover, and the air outlet of the air distribution pipe faces the chip removal port. Guide grooves are provided on both sides of the rotating cover, and the deburring assembly is located in the guide groove.

[0012] A corresponding dust collector is provided in the dust collecting chamber, and is connected to the rotating hood through the chip discharge port on the fixed ring, thereby forming a negative pressure in the rotating hood to collect the debris generated in the milling process. At the same time, the high-speed airflow generated by the air compressor is guided into the guide ring through the air supply hose, and then discharged through the air distribution pipes circumferentially arranged on the inner wall of the rotating hood, forming an upward airflow in the rotating hood to constrain the movement trajectory of the debris, thereby improving the efficiency of debris collection; in addition, the rotating hood can be driven by the rotating assembly to rotate freely along the fixed ring, thereby moving the deburring assembly installed in the guide groove to a suitable position.

[0013] Furthermore, the air distribution pipe is arranged obliquely, and the inclination direction of the air distribution pipe is the same as the rotation direction of the milling cutter.

[0014] During the milling operation, the generated debris will be thrown outward by the high-speed rotating milling cutter. The rotating airflow in the same direction as the milling cutter rotation is formed by the inclined air distribution pipe, which guides the movement of the debris and improves the efficiency of collecting the debris.

[0015] Furthermore, the rotating assembly includes a rotating motor, a transmission gear and a gear ring. The rotating motor is tightly connected to the fixed ring, the output end of the rotating motor is transmission-connected to the transmission gear, a working chamber is provided on the fixed ring, the transmission gear is located in the working chamber, the gear ring is tightly connected to the rotating cover, the tooth surface of the gear ring is transmission-connected to the transmission gear, and the rotating motor is electrically connected to the control system.

[0016] When the milling assembly moves on the workpiece with a fixed trajectory under the control of the control system, the rotating assembly is actuated, and the control system controls the rotating motor to start, driving the transmission gear to rotate a certain angle in the working chamber, thereby transmitting power to the gear ring meshing with it, and then driving the rotating cover to rotate around the fixed ring, so that the position of the deburring assembly is aligned with the milling direction, so that the deburring assembly can be smoothly inserted into the milled through groove on the workpiece, thereby deburring the through groove.

[0017] Furthermore, the deburring assembly includes an electric push rod, a sliding block, a vertical unit and a transverse unit. The electric push rod is tightly connected to the inner wall of the guide groove, the output end of the electric push rod is transmission-connected to the sliding block, the sliding block is slidingly connected to the guide groove, a first opening groove and a second opening groove are provided on the sliding block, the vertical unit is located in the first opening groove, and the vertical unit is used to remove burrs on the side of the heat sink, the transverse unit is located in the second opening groove, and the transverse unit is used to remove burrs on the top of the heat sink.

[0018] The milling depth of the milling cutter is controlled by a control system, which controls the movement of an electric push rod in a group of deburring components on the rear side of the milling direction, so that the downward movement distance of the sliding block is the same as the milling depth, thereby ensuring that the sliding block can be fully inserted into the milled through groove of the heat sink. Since the burrs in the through groove of the heat sink are mainly distributed on the side and top of the through groove, during the downward movement of the sliding block, since the first open groove and the second open groove are staggered, the vertical unit and the horizontal unit located therein will automatically pop out to scrape off the burrs in the through groove without interfering with each other, thereby realizing the simultaneous milling and deburring, and improving work efficiency.

[0019] Further, the vertical unit includes a vertical scraper and a connecting spring, the vertical scraper is slidably connected to the first opening groove, one end of the connecting spring is firmly connected to the vertical scraper, the other end of the connecting spring is firmly connected to the inner wall of the first opening groove, and the connecting spring is arranged in a plurality of groups in the first opening groove; When storing: the vertical scraper abuts against the inner wall of the guide groove.

[0020] When the sliding block is in the guide groove, the vertical unit is in a retracted state, the blade of the vertical scraper abuts against the inner wall of the guide groove, and the connecting spring is in a compressed state; when the sliding block slides out of the guide groove, under the elastic force of the connecting spring, the vertical scraper extends out of the first opening groove and abuts against the side of the heat sink groove, and moves synchronously with the milling assembly driven by the multi-axis module to scrape off the burrs on the side of the groove.

[0021] Further, the transverse unit includes a moving block, an electromagnet, a repelling magnet, a transverse scraper and a supporting spring, the moving block is slidably connected to the second open slot, a swinging cavity and an arc groove are provided in the moving block, the transverse scraper is rotatably connected to the swinging cavity, the electromagnet is tightly connected to the upper end of the second open slot, the electromagnet is electrically connected to the control system, the repelling magnet is tightly connected to the moving block, the facing ends of the repelling magnet and the electromagnet are the same magnetic poles, one end of the supporting spring is tightly connected to the moving block, the other end of the supporting spring is tightly connected to the bottom end of the inner wall of the second open slot, an arc spring is provided in the arc groove, and the arc spring is tightly connected to the transverse scraper; When storing: the transverse scraper abuts against the inner wall of the guide groove.

[0022] When the transverse unit is in the storage state, the transverse scraper abuts against the inner wall of the guide groove, and the arc spring is in a compressed state. When deburring is performed, under the elastic force of the arc spring, the transverse scraper will rotate outward along the swing cavity until it is horizontal, thereby removing the burrs on the top of the heat sink; in the initial state, under the action of the supporting spring, the moving block is located at the top of the second opening groove. Since the milling depth of the milling cutter is controlled by the control system, the smaller the milling depth, the shallower the through groove depth of the heat sink, the greater the current transmitted to the electromagnet by the control system, the greater the magnetic force of the electromagnet, and the greater the repulsive force exerted on the repulsive magnet, thereby driving the moving block to move downward along the second opening groove for a certain distance, so that the blade of the transverse scraper can abut against the top of the heat sink, thereby scraping off the burrs on the top of the heat sink.

[0023] Furthermore, an inclined surface is provided at the upper end of the vertical scraper.

[0024] The inclined surface allows the vertical scraper to smoothly slide into the first opening groove when the deburring assembly is retracted into the guide groove.

[0025] Compared with the prior art, the present invention has the following beneficial effects: 1. The control system can automatically control the multi-axis module to move along the set trajectory, thereby driving the milling mechanism to move above the workpiece, and then milling the required heat sink shape on the workpiece, thus realizing intelligent control of the processing process.

[0026] 2. Use the air compressor to provide high-speed airflow to the chip removal assembly. The high-speed airflow generated by the air compressor is guided into the guide ring through the air supply hose, and then discharged through the air distribution pipes circumferentially arranged on the inner wall of the rotating cover, forming an upward airflow in the rotating cover to constrain the movement trajectory of the debris, thereby improving the efficiency of debris collection.

[0027] 3. When deburring, the control system controls the movement of the electric push rod in a group of deburring components on the rear side of the milling direction, so that the distance the sliding block moves downward is the same as the milling depth, thereby ensuring that the sliding block can be fully inserted into the milled through groove of the heat sink. When the sliding block slides out of the guide groove, under the elastic force of the connecting spring, the vertical scraper extends out of the first opening groove and abuts against the side of the through groove of the heat sink, and as the milling component moves synchronously under the drive of the multi-axis module, the burrs on the side of the through groove are scraped off. Under the elastic force of the arc spring, the transverse scraper will rotate outward along the swing cavity until it is horizontal, thereby removing the burrs on the top end of the heat sink. The vertical scraper and the transverse scraper form an inverted L-shaped scraper combination, thereby synchronously removing the burrs on the side and top end of the through groove of the heat sink, realizing the simultaneous milling and deburring, and improving work efficiency.

[0051] The working principle of the present invention is as follows: during processing, the workpiece to be processed is first placed on the bed 1 for fixing, and then the set milling program is input into the control system 4. The control system 4 can automatically control the multi-axis module 2 to move along the set trajectory, thereby driving the milling mechanism 3 to move above the workpiece, and then milling the required heat sink shape on the workpiece. The chip removal component 32 collects the splashed debris and introduces it into the dust collection chamber in the installation cabinet 6 for collection; in addition, in order to improve the efficiency of collecting debris, an air compressor is used to provide a high-speed airflow to the chip removal component 32, and the movement trajectory of the debris is constrained by the high-speed airflow; when performing deburring operations, the control system 4 controls the electric push rod 331 in a group of deburring components 33 on the rear side of the milling direction to move, so that the sliding block The downward moving distance of 332 is the same as the milling depth, thereby ensuring that the sliding block 332 can be fully inserted into the milled through groove of the heat sink. When the sliding block 332 slides out of the guide groove 3221, under the elastic force of the connecting spring 3332, the vertical scraper 3331 extends out of the first opening groove 3321, abuts against the side of the heat sink through groove, and moves synchronously with the milling assembly 31 driven by the multi-axis module 2 to scrape off the burrs on the side of the through groove. Under the elastic force of the arc spring 3346, the transverse scraper 3344 will rotate outward along the swing cavity 33411 until it is horizontal, thereby removing the burrs on the top end of the heat sink. The vertical scraper 3331 and the transverse scraper 3344 form an inverted L-shaped scraper combination, thereby removing the burrs on the side and top end of the heat sink through groove.
