Description

Technical Field

[0001] This invention relates to the field of laser processing technology, and more specifically to a laser-based device for cutting the shells of various types of radiators. Background Technology

[0002] As a key component of the heat dissipation system of electronic devices, the heat sink housing has diverse shapes and complex structures, and usually requires high-precision cutting and drilling to meet heat dissipation and assembly requirements. Traditional processing methods such as stamping and milling have problems such as high mold costs, poor processing flexibility, and poor adaptability to complex curved surfaces.

[0003] Laser cutting technology, due to its advantages such as high precision, high flexibility, and non-contact operation, has been widely used in metal sheet processing. However, existing laser cutting equipment still has the following shortcomings when dealing with the production of diverse, small-batch heat sink housings: Poor versatility: Specialized fixtures are difficult to adapt quickly to different models and sizes of radiator housings, resulting in long changeover and adjustment times and impacting production efficiency.

[0004] Limited functionality: Most devices can only cut planes or simple contours, and their processing capabilities are limited for radiator housings that require precise grooving and cutting on cylindrical or complex curved surfaces.

[0005] Low level of automation: Positioning, parameter adjustment, dust removal and other processes still require a lot of manual intervention, making it difficult to achieve efficient and clean continuous production.

[0006] Environmental issues: The fumes and spatter generated during laser processing can pollute the working environment, affecting equipment lifespan and processing quality.

[0007] Therefore, there is an urgent need for a specialized cutting device that can quickly adapt to different models, integrate multiple processing functions, has a high degree of automation, and is environmentally friendly. Summary of the Invention

[0008] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-type heat sink shell cutting device based on laser processing to solve the problems existing in the background art.

[0009] This invention provides the following technical solution: a laser-based multi-type radiator shell cutting device, comprising a clamping base, the top of which is provided with a clamping mechanism for positioning and clamping the radiator shell; the device further comprises two symmetrically arranged processing components, which are mounted above the clamping base via a precision radial and height adjustment mechanism; the radial and height adjustment mechanism can drive the processing components to radially extend and retract and vertically rise and fall relative to the workpiece center to adapt to radiator shells of different models and curved surfaces; a laser and an angle adjuster for adjusting the laser angle are installed at the end of each processing component; a shell sealing cover is also provided above the clamping base, and a filter for purifying processing fumes is installed on the shell sealing cover; Furthermore, the clamping base includes a clamping chassis, the clamping chassis having an annular rotating groove in the center and toothed grooves on the inner sidewall of the rotating groove; the top of the clamping chassis has multiple radial clamping moving grooves around its central axis, and a clamping block is slidably installed in each clamping moving groove. The multiple clamping blocks together constitute the clamping mechanism, which is used to automatically center and clamp the radiator shell from the side.

[0010] Furthermore, the radial and height adjustment mechanism includes a vertical support frame, a telescopic rod, and an extension rod; the vertical support frame is connected to the toothed groove in the rotating groove via a second gear and is driven by a second transmission motor, allowing it to move along the rotating groove; the telescopic rod is fixed to the top of the vertical support frame and is used to drive the vertical support frame and the entire processing assembly connected thereto for height adjustment; the extension rod consists of two parts, with a distance sensor installed between the two parts to detect the overall elongation of the extension rod; one end of the extension rod is hinged to the processing assembly, and the support rod at the other end is installed in the detection support hole of the vertical support frame via a detection sleeve.

[0011] Furthermore, the detection sleeve integrates a current detector, and the support rod of the extension rod is made of metal. When the extension rod extends or shortens, its relative angle with the vertical support frame changes, causing the support rod to rotate within the detection sleeve. The current detector calculates the angle by detecting the change in resistance caused by the rotation, and combines the data from the distance sensor to comprehensively calculate the precise radial distance between the laser and the processing center.

[0012] Furthermore, the processing component includes a moving block, a control block, an angle adjuster, and a laser; the moving block is slidably mounted on the sliding groove of the central support plate; the control block is fixedly connected to the moving block; the angle adjuster is mounted on the bottom of the moving block, and the laser is mounted on the angle adjuster, with the angle adjuster controlling its light output angle.

[0013] Furthermore, the device also includes a first transmission assembly, which includes a first transmission motor and a threaded rod. The threaded rod passes through the control block and engages with a threaded hole in the middle. Activating the first transmission motor can drive the control block and the entire processing assembly to move linearly along the sliding groove, thereby achieving linear cutting of the workpiece.

[0014] Furthermore, the second drive motor drives the second gear to rotate through the first gear. The second gear meshes with the tooth groove of the rotating groove, thereby driving the vertical support frame to move along the annular rotating groove, causing the laser to move in a circle around the center of the workpiece, thus realizing the circumferential cutting of the cylindrical heat sink shell.

[0015] Furthermore, the two symmetrically arranged processing components can be controlled independently and can perform alternating multi-station processing; that is, while one set of processing components is processing at the current station, the other set of processing components can be pre-adjusted to the processing parameters of the next station. After the current station is completed, it can quickly move to the processing position to continue the work, greatly reducing the waiting time between processes.

[0016] Furthermore, the outer casing sealing cover and the clamping base together form a sealed processing space. The filter is an activated carbon filter or a HEPA filter, which is used to adsorb and filter harmful fumes and metal particles generated during laser processing, ensuring a clean working environment.

[0017] The technical effects and advantages of this invention are as follows: 1. This invention enables precise cutting and grooving operations on planes, cylinders, and even complex curved surfaces by using a first transmission component to achieve linear cutting, a second transmission motor to drive circular cutting, and an angle adjuster to adjust the laser angle. It is a comprehensive invention.

[0018] 2. This invention, by incorporating an integrated distance sensor and angle detection system, can accurately calculate and control the position of the laser head in real time. The dual processing component design supports multi-station pre-adjustment and alternating processing, greatly improving production efficiency and reducing equipment downtime.

[0019] 3. The present invention effectively collects and treats processing fumes by providing a closed dust removal system consisting of a sealed outer shell and a filter, thereby improving the working environment, protecting the health of operators, reducing the pollution of equipment optical components and moving parts by fumes, and extending the service life of the equipment.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The laser-based multi-type heat sink shell cutting device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Reference Figure 1-3 This invention provides a laser-based multi-type radiator shell cutting device, including a clamping base 1, which includes a clamping chassis 101. The clamping chassis 101 has an annular rotating groove 102 in the middle, and the inner sidewall of the rotating groove 102 is provided with toothed grooves. A second gear 11 is installed inside the rotating groove 102 and meshes with the toothed grooves. The top of the clamping chassis 101 has multiple radially distributed clamping moving grooves 103. A clamping block 15 is slidably installed on the clamping moving grooves 103 and positions and clamps the workpiece 14. Two sets of processing components 3 are installed on the clamping base 1. The two ends of the processing components 3 are installed on vertical support frames 6 through extension rods 5. Both vertical support frames 6 are installed in the rotating groove 102 and are controlled to move by a second drive motor 8. In this embodiment, it should be specifically explained that: the laser 304 at the bottom of the processing component 3 is a processing unit. When in use, the vertical support frame 6 is moved to form a circular processing trajectory, and the first transmission component 4 is used to form a straight processing trajectory. The composite processing of multiple types of radiator shells is achieved through the cooperation of the two sets of processing components 3.

[0029] The main difference between this embodiment and the prior art is that this embodiment uses a first transmission component to achieve linear cutting, and a second transmission motor to drive circumferential cutting. Combined with an angle adjuster to adjust the laser angle, it can complete precise cutting and grooving operations on planes, cylindrical surfaces and even complex curved surfaces. It has comprehensive functions, specifically in processing component 3. The above structure is the main structure of this embodiment, which solves the problem that special fixtures are difficult to quickly adapt to heat sink shells of different models and sizes, and the long adjustment time for model changeover affects production efficiency. The motor is an existing structure, and the specific structure and connection control method of the motor will not be described in detail in this embodiment.

[0030] Reference Figure 4 The processing component 3 includes a moving block 301, on which a control block 302 is fixedly connected. An angle adjuster 303 and a laser 304 are installed at the bottom of the moving block 301. The laser 304 emits laser light to process the processing position. The first transmission component 4 includes a first transmission motor and a threaded rod. The threaded rod is installed inside the control block 302. The first transmission component 4 drives the control block 302 to move, thereby moving the laser 304. A sliding groove 201 is provided on the side of the middle support plate 2. The moving block 301 is installed on the sliding groove 201. Extension rods 5 are installed at both ends inside the processing component 3. The bottom of the extension rods 5 is installed on the vertical support frame 6 through a support rod.

[0031] In this embodiment, it should be specifically explained that: the extension rod 5 consists of two parts, and a distance sensor is installed between the two parts. The distance sensor is used to detect the relative displacement between the extension rods 5 and thus determine the extension length of the extension rod 5. Combined with the diameter parameter of the rotating groove 102, the coordinates of the linear processing position of the laser 304 are calculated.

[0032] Reference Figure 5The vertical support frame 6 is equipped with a telescopic rod 7, which allows the vertical support frame 6 to move up and down to adjust the processing height of the laser 304. The vertical support frame 6 has a detection support hole 601, and a detection sleeve 602 is installed inside the detection support hole 601. The support rods at both ends of the extension rod 5 are installed on the detection sleeve 602. When adjusting the length of the extension rod 5, the processing component 3 and the extension rod 5 are relatively displaced, and the extension rod 5 is stretched as a whole. At the same time, the vertical support frame 6 moves and the relative angle between it and the extension rod 5 changes. The detection sleeve 602 determines the vertical distance of the laser 304 from the processing center by detecting the rotation angle of the bottom support rod of the extension rod 5. A second gear 11 is installed at the bottom of the vertical support frame 6. The second gear 11 meshes with a first gear 10 on the side. The first gear 10 is installed on a second drive motor 8, and the second drive motor 8 is installed on a horizontal support plate 9.

[0033] In this embodiment, it should be specifically noted that: the detection sleeve 602 integrates a current detector, the support rod of the extension rod 5 is a metal rod, and the current detector calculates the angle by detecting the change in current caused by the change in resistance when the support rod rotates. Combined with the distance sensor data in the extension rod 5, the spatial coordinate position of the laser 304 is determined.

[0034] Reference Figure 6 The clamping base 1 is covered with a housing sealing cover 12, which forms a sealed space for the processing space of the clamping base 1. A filter 13 is installed on the housing sealing cover 12. The filter 13 purifies the gas in the internal space during processing. The filter 13 adopts a combination of activated carbon filter and HEPA filter, which are used to adsorb harmful gases and intercept particulate matter, respectively, to ensure the cleanliness of the processing environment.

[0035] Working principle of the invention: The specific steps are as follows: S1: Place the workpiece 14 on the clamping base 1 and clamp it with the mirror-symmetrical clamping block 15 so that the workpiece 14 is located in the center position. S2: Control the rotation of a single second drive motor 8 according to the shape of the workpiece 14 and the processing requirements. The second drive motor 8 drives the second gear 11 to rotate through the first gear 10. Since the second gear 11 meshes with the tooth groove inside the rotating groove 102, the relative displacement occurs between the processing component 3 and the extension rod 5. The extension rod 5 is stretched as a whole. The vertical support frame 6 moves in position and the relative angle between it and the extension rod 5 changes. The detection sleeve 602 determines the vertical distance of the laser 304 from the processing center by detecting the rotation angle of the bottom support rod of the extension rod 5, so that the laser 304 is in the processing position. The laser 304 rotates through the angle adjuster 303 to determine the processing angle. S3: After the position adjustment of the laser 304 is completed, when processing a circular workpiece, the two second drive motors 8 are rotated synchronously to control the overall rotation of the processing assembly 3. The laser 304 performs circular motion to process the workpiece at the processing position. When a straight position needs to be processed, the second drive motor 8 is controlled to rotate to the specified angle, and the first drive assembly 4 is started. The first drive assembly 4 controls the threaded rod to rotate and drive the control block 302 to move. At this time, the laser 304 performs straight processing on the workpiece 14. S4: When multi-station processing is required, the two sets of processing components 3 are controlled by adjusting back and forth. That is, when one set of processing components 3 is processing, the other set adjusts the height and length according to the parameters of the next processing position. After the adjustment is completed, after the first set is processed, the second set moves to the processing position to process. S5: During processing, the outer casing sealing cover 12 covers the processing position, and the filter 13 is activated to filter the smoke generated by laser processing.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
