Description

Technical Field

[0001] The invention belongs to the technical field of vapor chamber production, and in particular relates to a vapor chamber welding device. Background Art

[0002] A vapor chamber is a highly efficient heat dissipation device, mainly used for thermal management in electronic devices such as laptops, servers and high-performance mobile phones. Its working principle is based on the process of liquid evaporation and condensation to transfer heat. Specifically, a small amount of working fluid is contained inside the vapor chamber. After absorbing heat in the heat absorption area, the liquid evaporates into gas, and the gas then flows to the condensation area, where it releases heat and recondenses into liquid. Then, the liquid returns 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 device. The manufacturing of the vapor chamber usually 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, water injection, primary degassing, secondary degassing and sealing, aging and performance testing. The upper and lower covers are usually welded by laser welding, ultrasonic welding or resistance welding to ensure reliable connection even in high temperature environment. Prior art publication number CN112815750A discloses a method for manufacturing a vapor chamber, a vapor chamber and a middle frame vapor chamber. During the manufacturing process of the vapor chamber, no inspection of the flatness 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 vapor chamber. If the solder is worn during use, the existence of the gap between the upper and lower covers will directly cause the gas to escape from the vapor chamber and fail. At the same time, the flatness problem will also affect the thermal conductivity of the vapor chamber during later use. At the same time, the prior art lacks cooling treatment during the welding process, and there is a large residual stress influence in the actual welding process. The residual stress is likely to be released during subsequent use, causing the vapor chamber to deform or break, resulting in failure of the vapor chamber. Summary of the invention

[0019] The present invention provides the following embodiments.

[0020] Example 1

[0021] The embodiment of the present invention provides a heat plate welding device, such as Figure 1-8 As shown, it includes a welding table 1 and an ultrasonic welding robot arm 4, the welding table 1 is rotatably connected to a carrier 2, the carrier 2 is slidably connected to an auxiliary welding mechanism 3, the auxiliary welding mechanism 3 includes a flatness detection component 300 and a heat spreader clamp 301, and the heat spreader clamp 301 is used to clamp the upper cover and the lower cover of the heat spreader; 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 number of pressure sensors are arranged on the flatness detection roller 3000. A water cooling assembly is arranged inside the flatness detection roller 3000. The pressure sensors are used to detect the flatness of the welding surfaces of the upper cover and the lower cover of the heat spreader. The water cooling assembly is used to cool the heat spreader during welding. The surface of the flatness detection roller 3000 adopts electrostatic adsorption material.

[0022] Preferably, it also includes a plate picking robot arm 100, a plate picking robot arm 2 101 and a plate picking robot arm 3 102. The plate picking robot arm 100 is provided with a plate feeding conveyor belt 1000 on the side, the plate picking robot arm 2 101 is provided with a plate discharging conveyor belt 1010 on the side, and the plate picking robot arm 3 102 is provided with a plate recovery box 1020 on the side.

[0023] Preferably, the flatness detection assembly 300 and the heat spreader fixture 301 are installed on a mounting slide 302 , and the mounting slide 302 is slidably connected to the carrier 2 .

[0024] Preferably, the water cooling component is a medium coil, in which cooling heat-conducting medium is stored, and the medium coil is connected to an external medium storage box through a pump body.

[0025] Preferably, the pressure sensor is electrically connected to a data processor, and the data processor is used to analyze the detection data of the pressure sensor to obtain the pressure distribution of the welding surface, and then determine whether the flatness of the upper cover and the lower cover of the heat spreader is qualified.

[0026] The working principle and beneficial effects of the above technical solution are as follows: when working, the upper cover and the lower cover of the heat spreader are input to the plate picking robot arm 100 through the plate feeding conveyor belt 1000, and the plate picking robot arm 100 performs appearance quality inspection on the upper cover and the lower cover of the heat spreader and then installs them on the heat spreader fixture 301, and then the flatness detection component 300 drives the flatness detection roller body 3000 to move through the roller body control component, and performs flatness detection on the welding surface of the upper cover and the lower cover of the heat spreader. During the detection process, the surface is cleaned at the same time. If the flatness is qualified, the upper cover and the lower cover of the heat spreader are welded, and the flatness detection roller is used during the welding process. The contact between the body 3000 and the surface of the heat spreader is used to cool the heat spreader. After welding is completed, the image acquisition device on the ultrasonic welding robot arm 4 is used to acquire images of the welding interface, and the image acquisition results are input into the trained welding quality assessment model to evaluate the welding quality of the heat spreader. If the welding quality is good, the plate picking robot arm 2 101 removes the welded heat spreader and places it on the plate delivery 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 spreader does not meet the standard, the plate picking robot arm 3 102 puts the heat spreader or the upper cover or the lower cover of the heat spreader that does not meet the standard into the plate recycling box 1020. The present invention performs a flatness detection on the welding surface before welding the heat spreader, thereby avoiding the problem of heat spreader failure and poor thermal conductivity during use due to flatness problems. At the same time, the heat spreader is cooled during welding by the contact between the flatness detection roller 3000 and the surface of the heat spreader, which effectively avoids the influence of residual stress on the heat spreader itself during welding. Automated equipment such as the plate picking robot arm 101, the plate feeding conveyor belt 1000 and the plate discharging conveyor belt 1010 are introduced to improve production efficiency and automation level.

If the upper cover of the heat spreader plate and the lower cover of the heat spreader plate are When the flatness is qualified, the driving motor 3038 is rotated to drive the clamping cylinder 3036 to rotate and drive the upper cover of the heat spreader to rotate to the vertical table surface and the welding surface of the upper cover of the heat spreader is opposite to the welding surface of the lower cover of the heat spreader, and then the auxiliary clamp assembly 303 drives the upper cover of the heat spreader to move to the electric telescopic block 2 3044, and at the same time, the auxiliary extrusion cam 3048 rotates to push the lower cover of the heat spreader to move in the direction of the upper cover of the heat spreader until the lower cover of the heat spreader and the upper cover of the heat spreader are tightly fitted. At this time, the side of the fitting surface of the lower cover of the heat spreader and the upper cover of the heat spreader is located in the gap between the electric telescopic block 1 3043 and the electric telescopic block 2 3044, which is convenient for the ultrasonic welding robot arm 4 to weld the heat spreader. After welding one side, the electric telescopic turntable 3041 rotates 90 degrees to weld the next side. When the electric telescopic strip 1 3043 and the electric telescopic strip 2 3044 are clamped, it is achieved by sliding the strip 2 3047 inside the strip 1 3046. The combination of the flatness detection roller 3000 and the auxiliary extrusion cam 3048 ensures the precise docking and welding of the upper cover and the lower cover of the heat spreader.

[0038] Preferably, the heat sink push assembly 502 includes an electric push screw 5020, which is rotatably connected to the housing 500 of the storage mechanism, and a push nut 5021 is threadedly connected to the electric push screw 5020, and a push bar 5022 is fixedly connected to the push nut 5021, and the push bar 5022 is slidably connected to the push bar slide groove 5024 of the transition plate 5023; The heat spreader assembly 503 includes a mounting frame 5030, in which a mounting rod 5031 is slidably connected up and down, a downward pressing elastic member 5032 is provided on the mounting rod 5031, and a tidying roller 5033 is rotatably connected to the bottom of the mounting frame 5030; The heat spreader lifting and bundling assembly 504 includes a bundling assembly lifting motor 5040, the output end of the bundling assembly lifting motor 5040 is fixedly connected to a bundling assembly lifting screw 5041, the bundling assembly lifting screw 5041 is threadedly connected to a bundling assembly lifting nut 5042, the bundling assembly lifting nut 5042 is slidably connected to the side wall of the collection and sorting mechanism shell 500, and is fixedly connected to the lifting and bundling machine 5043, the lifting and bundling machine 5043 is slidably connected to an electric back plate 5044, the lifting and bundling machine 5043 is fixedly connected to two symmetrically arranged back plate guide rods 5045, the electric back plate 5044 is slidably connected to the back plate guide rods 5045, and the inner wall of the collection and sorting mechanism shell 500 is provided with a push-out cylinder 5046.

[0039] The working principle and beneficial effects of the above technical solution are as follows: the welded vapor chamber is output to the collection mechanism 5 through the plate discharging conveyor belt 1010, and then pushed to the vapor chamber lifting and bundling assembly 504 through the vapor chamber pushing assembly 502, and after being assisted by the vapor chamber collecting assembly 503 for regularization, the vapor chamber lifting and bundling assembly 504 bundles a plurality of stacked vapor chambers, and after bundling is completed, the vapor chamber lifting and bundling assembly 504 moves downward to the preset position and the bundled vapor chambers thereon are pushed out; Specifically, the welded heat spreader is output to the heat spreader pushing assembly 502 via the plate output conveyor belt 1010. At this time, the electric pushing screw 5020 rotates to drive the pushing nut 5021 to move, and the pushing nut 5021 drives the pushing bar 5022 to slide in the pushing bar slide groove 5024, and at the same time pushes the heat spreader to move in the direction of the heat spreader lifting and bundling assembly 504. At this time, the heat spreader lifting and bundling assembly 504 and the transition plate 5023 are at the same height, and the first heat spreader is pushed onto the lifting and bundling machine 5043. Since the feeding end of the lifting and bundling machine 5043 is an inclined surface, the front end of the subsequent heat spreader will be inserted under the previous heat spreader during the process of being pushed to the lifting and bundling machine 5043, thereby gradually realizing the stacking of the heat spreaders. The plate 5044 can move left and right according to the actual size of the heat spreader and the bundling requirements, so that one side of the heat spreader abuts against the electric back plate 5044 to ensure that the heat spreaders are stacked neatly. At the same time, during the stacking process, the sorting roller 5033 always abuts against the surface of the uppermost heat spreader to prevent the position of the upper heat spreader from being offset during the insertion of subsequent heat spreaders. After the lifting and bundling machine 5043 has finished bundling, the bundling assembly lifting motor 5040 drives the bundling assembly lifting screw 5041 to rotate, and the bundling assembly lifting 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 push-out cylinder 5046, and then the push-out cylinder 5046 extends to push out the packaged heat spreader; The design of the collection and bundling mechanism 5 enables the welded heat spreaders to be quickly and orderly stacked and bundled, thereby improving production efficiency. The combination of the heat spreader pushing assembly 502, the heat spreader collection assembly 503 and the heat spreader lifting and bundling assembly 504 realizes the whole process of processing the heat spreader, from pushing, stacking to bundling, to ensure product quality.

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.

[0041] 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; 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. 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.
