Description

Technical Field

[0001] The present invention belongs to the technical field of heat pipe production, and particularly relates to a heat pipe welding device. Background Art

[0002] A heat pipe is an efficient heat dissipation device mainly used for heat management in electronic devices such as laptops, servers, and high-performance mobile phones. Its working principle is based on the processes of liquid evaporation and condensation to transfer heat. Specifically, a small amount of working fluid is contained inside the heat pipe. After the heat absorption area absorbs heat, the liquid evaporates into gas, and the gas then flows to the condensation area, where it releases heat and re-condenses into liquid. Then, these liquids return to the heat absorption area through capillary action or gravity, thus forming a cycle that effectively transfers heat from the heat source to the radiator or other cooling devices;

[0003] The manufacturing of heat pipes generally includes stamping or etching the upper and lower covers, assembling the wick, welding the upper and lower covers, sintering and leveling, connecting the water injection pipe, injecting water, primary degassing, secondary degassing and sealing, aging, and performance testing. The welding of the upper and lower covers usually adopts methods such as laser welding, ultrasonic welding, or resistance welding to ensure reliable connection even in high-temperature environments;

[0004] The prior art publication number CN112815750A discloses a manufacturing method of a heat pipe, a heat pipe, and a middle frame heat pipe. During the manufacturing process of the heat pipe, no flatness inspection of the welding surface is performed before welding the upper and lower covers. The flatness of the welding surface will seriously affect the airtightness inside the heat pipe. If the solder wears during use, the existence of the gap between the upper and lower covers will directly cause gas to escape and the heat pipe to fail. At the same time, the flatness problem will also affect the thermal conductivity of the heat pipe during subsequent use. At the same time, the prior art lacks cooling treatment during the welding process, and there are significant residual stress effects during the actual welding process. The residual stress is likely to be released during subsequent use, causing deformation or fracture of the heat pipe and resulting in the failure of the heat pipe. Summary of the Invention

[0041] The present invention provides the following embodiments.

[0042] Embodiment 1

[0043] An embodiment of the present invention provides a heat sink welding device, as Figures 1-8 shown, which includes a welding table 1 and an ultrasonic welding robotic arm 4. A carrier 2 is rotatably connected to the welding table 1, and an auxiliary welding mechanism 3 is slidably connected to the carrier 2. The auxiliary welding mechanism 3 includes a flatness detection assembly 300 and a heat sink clamp 301. The heat sink clamp 301 is used for clamping the upper heat sink cover and the lower heat sink cover.

[0044] The flatness detection assembly 300 includes a roller control assembly and a flatness detection roller 3000. The flatness detection roller 3000 is installed on the roller control assembly. The roller control assembly is used to drive the flatness detection roller 3000 to move. A plurality of pressure sensors are provided on the flatness detection roller 3000, and a water cooling assembly is provided inside the flatness detection roller 3000. The plurality of pressure sensors are used to detect the flatness of the welding surfaces of the upper heat sink cover and the lower heat sink cover. The water cooling assembly is used to cool the heat sink during welding. The surface of the flatness detection roller 3000 is made of an electrostatic adsorption material.

[0045] Preferably, it further includes a board picking robotic arm one 100, a board picking robotic arm two 101, and a board picking robotic arm three 102. An inlet board conveyor belt 1000 is provided on the side of the board picking robotic arm one 100, an outlet board conveyor belt 1010 is provided on the side of the board picking robotic arm two 101, and a board recycling box 1020 is provided on the side of the board picking robotic arm three 102.

[0046] Preferably, the flatness detection assembly 300 and the heat sink clamp 301 are installed on an installation sliding plate 302, and the installation sliding plate 302 is slidably connected to the carrier 2.

[0047] Preferably, the water-cooling component is a medium coil pipe, a cooling heat-conducting medium is stored in the medium coil pipe, and the medium coil pipe is communicated with an external medium storage tank through a pump body.

[0048] Preferably, the pressure sensor is electrically connected to the data processor, and the data processor is configured to analyze the detection data of the pressure sensor to obtain the pressure distribution of the welding surface, and further determine whether the flatness of the upper cover and the lower cover of the heat sink is qualified.

[0049] The working principle and beneficial effects of the above technical solution are as follows: During operation, the upper cover and the lower cover of the heat sink are input to the first plate-picking robot arm 100 through the feeding conveyor belt 1000. After the appearance quality inspection of the upper cover and the lower cover of the heat sink, the first plate-picking robot arm 100 installs them on the heat sink fixture 301. Then, the flatness detection assembly 300 drives the flatness detection roller 3000 to move through the roller control assembly to detect the flatness of the welding surfaces of the upper cover and the lower cover of the heat sink. During the detection process, surface cleaning is performed simultaneously. If the flatness is qualified, the upper cover and the lower cover of the heat sink are welded. During the welding process, the heat sink is cooled by the contact between the flatness detection roller 3000 and the surface of the heat sink. After welding, the image collector on the ultrasonic welding robot arm 4 collects images of the welding joints, and inputs the image collection results into the trained welding quality evaluation model to evaluate the welding quality of the heat sink. If the welding quality is good, the second plate-picking robot arm 101 removes the welded heat sink and places it on the discharging conveyor belt 1010. If the welding quality does not meet the standard or the flatness of the welding surface of the upper cover or the lower cover of the heat sink does not meet the standard, the third plate-picking robot arm 102 puts the non-conforming heat sink or the upper cover or the lower cover of the heat sink into the sheet metal recycling box 1020;

[0050] Before welding the heat sink, the present invention detects the flatness of the welding surface, avoiding the problems of heat sink failure and poor heat conduction performance during use caused by flatness problems. At the same time, during the welding process, the heat sink is cooled by the contact between the flatness detection roller 3000 and the surface of the heat sink, effectively avoiding the influence of residual stress on the heat sink itself during the welding process. The introduction of automated equipment such as the second plate-picking robot arm 101, the feeding conveyor belt 1000, and the discharging conveyor belt 1010 improves the production efficiency and automation level.

[0051] Embodiment 2

[0052] On the basis of Embodiment 1, the roller control assembly includes two symmetrically arranged lifting cylinders 3001. The lifting cylinders 3001 are fixedly connected to the mounting slide plates 302 of the carrier 2. The working end of the lifting cylinder 3001 is fixedly connected to a first carrier plate 3002. A push-pull cylinder 3003 is fixedly connected to the first carrier plate 3002. The working end of the push-pull cylinder 3003 is fixedly connected to a second carrier plate 3004. A push-pull guide rod 3005 is fixedly connected to the first carrier plate 3002. The second carrier plate 3004 is slidably connected to the push-pull guide rod 3005. The flatness detection roller 3000 is rotatably connected to the second carrier plate 3004.

[0053] The working principle and beneficial effects of the above technical solution are as follows: When the roller control assembly works, the lifting cylinder 3001 expands and contracts to drive the first carrier plate 3002 to lift, thereby driving the flatness detection roller 3000 to move up and down. Thus, the flatness detection roller 3000 rolls on the surface of the heat sink plate, so as to obtain the pressure value, and at the same time achieve the adsorption and cleaning effect. The push-pull cylinder 3003 expands and contracts to drive the second carrier plate 3004 to slide along the push-pull guide rod 3005, thereby adjusting the distance between the flatness detection roller 3000 and the surface of the heat sink plate and controlling the operation of the pressure sensor;

[0054] The lifting cylinder 3001 and the push-pull cylinder 3003 are used to accurately control the height and distance of the flatness detection roller 3000, ensuring that the pressure sensor can accurately detect the flatness of the welding surface. The flatness detection roller 3000 can not only perform flatness detection, but also achieve surface cleaning through lifting and moving.

[0055] Embodiment 3

[0056] On the basis of Embodiment 2, a motor mounting block 3006 is fixedly connected to the second carrier plate 3004. A driving motor 3007 is fixedly connected to the motor mounting block 3006. A first micro pulley 3008 is fixedly connected to the output end of the driving motor 3007. A second micro pulley 3009 is fixedly connected to the flatness detection roller 3000. The first micro pulley 3008 and the second micro pulley 3009 are connected by a micro transmission belt 3020;

[0057] An electric swing arm 3021 is rotatably connected to the second carrier plate 3004. A negative pressure dust suction roller 3022 is rotatably connected to the electric swing arm 3021. A plurality of dust suction holes are provided on the surface of the negative pressure dust suction roller 3022.

[0058] The working principle and beneficial effects of the above technical solution are as follows: during the pressure detection process, the driving motor 3007 drives the micro pulley 1 3008 to rotate, the micro pulley 1 3008 drives the micro transmission belt 3020 to transmit, the micro transmission belt 3020 drives the micro pulley 2 3009 to rotate, and the micro pulley 2 3009 drives the flatness detection roller 3000 to rotate, thereby realizing the rolling of the flatness detection roller 3000 on the heat soaking plate, providing a rotation driving force to avoid the rolling of the flatness detection roller 3000 from being stuck, and ensuring the accuracy and reliability of the pressure sensor detection value;

[0059] When there are many impurities attached to the flatness detection roller body 3000 , the electric swing arm 3021 rotates to make the negative pressure dust suction roller 3022 approach the flatness detection roller body 3000 , thereby cleaning the impurities on the surface of the flatness detection roller body 3000 .

[0061] On the basis of Example 1, the vapor chamber fixture 301 includes an auxiliary fixture component 303 and an execution fixture component 304;

[0063] The working principle and beneficial effects of the above technical solution: the plate picking robot arm 100 installs the upper cover of the heat spreader on the auxiliary fixture assembly 303, and installs the lower cover of the heat spreader on the execution fixture assembly 304. During the installation process, the welding surfaces of the upper cover and the lower cover of the heat spreader are initially oriented toward the flatness detection roller body 3000;

[0064] The pick-up manipulator 100 of the heat sink plate clamps the upper cover of the heat sink plate at a suitable position in the air. Then, the electric displacement lead screw 3032 rotates to drive the displacement nut 3031 to move, thereby driving the lead screw mounting seat 3030 and the clamping strip 3037 to move to a suitable position. Then, the clamping cylinder 3036 extends to drive the two clamping strips 3037 to move towards each other to clamp the upper cover of the heat sink plate. Then, the rotation drive motor 3038 drives the clamping cylinder 3036 to rotate to drive the upper cover of the heat sink plate to rotate to the direction perpendicular to the table surface, facilitating the flatness detection of the upper cover of the heat sink plate. The height of the upper cover of the heat sink plate can be adjusted by rotating the electric adjustment lead screw 3033 to drive the adjustment nut 3034 to move up and down.

[0065] Embodiment 5

[0066] On the basis of Embodiment 4, the execution fixture assembly 304 includes a mounting vertical plate 3040. An electric telescopic turntable 3041 is rotatably connected to the mounting vertical plate 3040, and an execution fixture is detachably connected to the electric telescopic turntable 3041.

[0067] The execution fixture includes a back plate 3042. Two symmetrically arranged fixture bodies are slidably connected to the back plate 3042. The fixture body includes an electric telescopic strip 3043 and an electric telescopic strip 3044. The electric telescopic strip 3043 and the electric telescopic strip 3044 are connected by a U-shaped welding rod 3045. Both the electric telescopic strip 3043 and the electric telescopic strip 3044 include a strip 3046 and a strip 3047. The strip 3047 is slidably connected inside the strip 3046.

[0068] An auxiliary extrusion cam 3048 is rotatably connected inside the electric telescopic turntable 3041.

[0069] The working principle and beneficial effects of the above technical solution are as follows: The pick-up manipulator 100 installs the lower cover of the heat sink on the two electric telescopic strip blocks 3043 on the execution fixture assembly 304. Then, the flatness detection roller body 3000 first detects the flatness of the upper cover of the heat sink. If the detection is unqualified, it will be removed. If the detection is qualified, the electric adjustment screw 3033 rotates to drive the upper cover of the heat sink to move upward. At the same time, the rotation drive motor 3038 drives the clamping cylinder 3036 to rotate to drive the upper cover of the heat sink to rotate to the parallel table direction, reserving space for the flatness detection of the lower cover of the heat sink. Then, the flatness detection roller body 3000 passes through the reserved space and contacts the lower cover of the heat sink in the two electric telescopic strip blocks 3043 to detect the flatness of the lower cover of the heat sink. If the flatness between the upper cover and the lower cover of the heat sink is qualified, the rotation drive motor 3038 drives the clamping cylinder 3036 to rotate to drive the upper cover of the heat sink to rotate to be perpendicular to the table and the welding surface of the upper cover of the heat sink is opposite to the welding surface of the lower cover of the heat sink. Then, the auxiliary fixture assembly 303 drives the upper cover of the heat sink to move to the electric telescopic strip block 3044. At the same time, the auxiliary extrusion cam 3048 rotates to push the lower cover of the heat sink to move towards the upper cover of the heat sink until the lower cover and the upper cover of the heat sink are closely attached. At this time, the side surface of the attachment surface of the lower cover and the upper cover of the heat sink is located at the gap between the electric telescopic strip block 3043 and the electric telescopic strip block 3044, which is convenient for the ultrasonic welding manipulator 4 to weld the heat sink. After welding one side, the electric telescopic turntable 3041 rotates 90 degrees to weld the next side;

[0070] When the electric telescopic strip block 3043 and the electric telescopic strip block 3044 clamp, they are both realized by the sliding of the strip block 3047 in the strip block 3046. The combination of the flatness detection roller body 3000 and the auxiliary extrusion cam 3048 ensures the precise docking and welding of the upper and lower covers of the heat sink.

The finishing mechanism housing 500 is provided with a heat sink pushing assembly 502, a heat sink finishing assembly 503, and a heat sink lifting and bundling assembly 504.

[0074] Preferably, the heat sink pushing assembly 502 includes an electric pushing lead screw 5020 rotatably connected within the housing 500 of the sorting mechanism. A pushing nut 5021 is threadedly connected to the electric pushing lead screw 5020. A pushing bar 5022 is fixedly connected to the pushing nut 5021 and is slidably connected within a pushing bar chute 5024 of a transition plate 5023.

[0075] The heat sink sorting assembly 503 includes a mounting frame 5030. A sorting rod 5031 is slidably connected vertically within the mounting frame 5030. A first downward pressing elastic member 5032 is provided on the sorting rod 5031. A sorting roller 5033 is rotatably connected to the bottom of the sorting rod 5031.

[0076] The heat sink lifting and bundling assembly 504 includes a bundling assembly lifting motor 5040. A bundling assembly lifting lead screw 5041 is fixedly connected to the output end of the bundling assembly lifting motor 5040. A bundling assembly lifting nut 5042 is threadedly connected to the bundling assembly lifting lead screw 5041. The bundling assembly lifting nut 5042 is slidably connected to the side wall of the housing 500 of the sorting mechanism and is fixedly connected to a lifting bundling machine 5043. An electric back plate 5044 is slidably connected to the lifting bundling machine 5043. Two symmetrically arranged back plate guide rods 5045 are fixedly connected to the lifting bundling machine 5043. The electric back plate 5044 is slidably connected to the back plate guide rods 5045. A pushing cylinder 5046 is provided on the inner wall of the housing 500 of the sorting mechanism.

[0077] The working principle and beneficial effects of the above technical solution are as follows: The heat sinks after welding are output by the plate output conveyor belt 1010 to the sorting mechanism 5. Then, they are pushed by the heat sink pushing assembly 502 onto the heat sink lifting and bundling assembly 504. After being assisted by the heat sink sorting assembly 503 for sorting, the heat sink lifting and bundling assembly 504 bundles several stacked heat sinks. After bundling, the heat sink lifting and bundling assembly 504 moves downward to a preset position, and the bundled heat sinks thereon are pushed out.

[0078] Specifically, the heat sink plate after welding is output to the heat sink plate pushing assembly 502 through the plate output conveyor belt 1010. At this time, the electric pushing lead screw 5020 rotates to drive the pushing nut 5021 to move. The pushing nut 5021 drives the push bar 5022 to slide in the push bar chute 5024, and at the same time pushes the heat sink plate towards the heat sink plate lifting and bundling assembly 504. At this time, the heat sink plate lifting and bundling assembly 504 and the transition plate 5023 are at the same height. The first heat sink plate is pushed onto the lifting and bundling machine 5043. Since the feeding end of the lifting and bundling machine 5043 is inclined, the front end of the subsequent heat sink plates will be inserted under the previous heat sink plate during the process of being pushed onto the lifting and bundling machine 5043, thereby gradually realizing the stacking of the heat sink plates. During the stacking process, the electric back plate 5044 can move left and right according to the actual size and bundling requirements of the heat sink plate, so that one side of the heat sink plate abuts against the electric back plate 5044, ensuring that the heat sink plates are stacked neatly. At the same time, during the stacking process, the sorting roller 5033 always abuts against the surface of the uppermost heat sink plate, preventing the position of the upper heat sink plate from shifting during the insertion of the subsequent heat sink plates. After the lifting and bundling machine 5043 finishes bundling, the bundling assembly lifting motor 5040 drives the bundling assembly lifting lead screw 5041 to rotate. The bundling assembly lifting lead screw 5041 drives the bundling assembly lifting nut 5042 to move downward, thereby driving the lifting and bundling machine 5043 to move downward to the same height as the pushing cylinder 5046. Then, the pushing cylinder 5046 extends to push out the bundled heat sink plates;

[0079] The design of the sorting mechanism 5 enables the heat sink plates after welding to be stacked and bundled quickly and orderly, improving the production efficiency. The combination of the heat sink plate pushing assembly 502, the heat sink plate sorting assembly 503, and the heat sink plate lifting and bundling assembly 504 realizes the whole process treatment of the heat sink plates, from pushing, stacking to bundling, ensuring the product quality.

[0080] Embodiment 7

[0081] Based on Embodiment 6, it further includes a cleaning, sampling and quality inspection component 505. The cleaning, sampling and quality inspection component 505 includes a position adjustment slide bar 5050. The position adjustment slide bar 5050 is fixedly connected to the mounting frame 5030. An electric slider 5051 is slidably connected to the position adjustment slide bar 5050. An adjustment guide cylinder 5052 is fixedly connected to the electric slider 5051. A connecting rod member 5053 is slidably connected up and down in the adjustment guide cylinder 5052. The connecting rod member 5053 is connected to the adjustment guide cylinder 5052 through a second downward pressing elastic member 5054. A first cleaning and quality inspection head 5055 is installed on the connecting rod member 5053. A second cleaning and quality inspection head 5056 is slidably connected in the transition plate 5023. A heating robotic arm 5057 is provided on the transition plate 5023;

[0082] The cleaning quality inspection head 1 5055 and the cleaning quality inspection head 2 5056 both include a U-shaped carrier block 5058 and a cleaning quality inspection roller 5059. The cleaning quality inspection roller 5059 is provided with a negative pressure mechanism. The cleaning quality inspection roller 5059 is provided with dust suction holes and a plurality of temperature sensors. The two U-shaped carrier blocks 5058 are connected by a micro telescopic rod.

[0083] The working principle and beneficial effects of the above technical solution are as follows: when the heat spreader passes through the heating mechanical arm 5057, the heating mechanical arm 5057 heats the position of the liquid cooling plate substrate, and then sends it between the cleaning quality inspection head 1 5055 and the cleaning quality inspection head 2 5056. In the process of passing through the cleaning quality inspection head 1 5055 and the cleaning quality inspection head 2 5056, the cleaning quality inspection roller 5059 cleans the surface and detects the temperature of the surface, and transmits the detection result to the data processor, and obtains the temperature distribution of the heat spreader at this time through data analysis, so as to analyze whether the heat spreader is qualified;

[0084] The U-shaped carrier block 5058 is designed with raised ends to ensure that the heat spreader can smoothly enter between the cleaning inspection head 1 5055 and the cleaning inspection head 2 5056. The electric slider 5051 and the position adjustment slide bar 5050 are designed to facilitate the adjustment of the positions of the cleaning inspection head 1 5055 and the cleaning inspection head 2 5056. The design of the downward pressing elastic member 2 5054 can ensure that the cleaning inspection head 1 5055 is always in contact with the heat spreader.

[0085] The design of the clean sampling quality inspection component 505 can perform real-time temperature detection and surface cleaning during the production process of the heat sink to ensure that the product meets quality standards. The design of the electric slider 5051 and the position adjustment slide bar 5050 allows the positions of the clean quality inspection head 1 5055 and the clean quality inspection head 2 5056 to be flexibly adjusted to meet different production needs.
