[0002] The heat transfer principle of the heat spreader is to transfer heat through the phase change of water or other working fluids in the heat spreader at the evaporation end and the condensation end.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] The following is the attached Figure 1 To Attachment Figure 6 , describing the water injection module of the first embodiment of the present invention.

[0025] Reference Figure 1 According to some embodiments of the present invention, the water injection module includes a water injection component 200 and a liquid injection drive mechanism 300; wherein the water injection component 200 is used to inject water into the heat spreader, and the liquid injection drive component is connected to the water injection component 200, and is used to drive the water injection component 200 to rise and fall in the vertical direction, so that the water injection component 200 can descend and dock with the heat spreader located below it to complete the water injection, and after the water injection is completed, the water injection component 200 can rise and be separated from the heat spreader.

[0026] Reference Figures 1 to 4Specifically, the water injection assembly 200 includes an injection valve 210, an injection needle 220 and a protective sleeve 230; wherein the injection valve 210 contains a liquid medium such as ultrapure water, and can eject the liquid medium through the injection hole at the bottom of the injection valve 210 according to the set injection amount; the injection needle 220 and the protective sleeve 230 are vertically arranged at the bottom of the injection valve 210, and the upper ends of the injection needle 220 and the protective sleeve 230 are connected to the injection end at the bottom of the injection valve 210, and the diameter of the protective sleeve 230 is It is larger than the diameter of the injection needle 220 and is sleeved on the outside of the injection needle 220 to protect the injection needle 220; the upper end of the injection needle 220 is connected to the injection hole of the injection valve 210, so that the liquid working medium sprayed through the injection hole will flow into the injection needle 220; the diameter of the protective sleeve 230 is smaller than the inner diameter of the injection tube on the heat spreader, so that when the injection drive mechanism 300 drives the water injection assembly 200 to rise and fall, the lower ends of the injection needle 220 and the protective sleeve 230 can penetrate into or exit the injection tube of the heat spreader together.

[0027] It should be understood that the water injection module of this embodiment sets a protective sleeve 230 on the outside of the protective sleeve 230 so that during the injection process, the protective sleeve 230 can follow the injection needle 220 and penetrate into the injection tube of the heat spreader under the drive of the injection drive mechanism 300, so that the injection needle 220 can be protected by the protective sleeve 230, so that the diameter of the injection needle 220 can be made thin enough to ensure the water injection accuracy, and it is not easy to bend and deform due to obstruction (such as blockage or bending of the injection tube of the heat spreader), which is beneficial to increase the service life of the injection needle 220 and improve the injection efficiency.

[0028] It should be understood that the heat spreader includes a main body and an injection tube, wherein the injection tube is arranged at the top of the main body, and a tapered channel with a larger top and a smaller bottom is arranged on the top of the main body to connect the injection tube and a chamber for accommodating the working medium arranged inside the main body; in order to make the protective sleeve 230 have sufficient rigidity and strength, and at the same time enable the injection needle 220 to enter the chamber inside the main body through the tapered channel to directly inject water, thereby avoiding the accumulation of a large amount of working medium such as ultrapure water in the injection tube and affecting the water injection effect, in some embodiments, reference is made to Figure 4The lower end of the injection needle 220 extends to the outside of the protective sleeve 230, so that the lower end of the injection needle 220 can penetrate into the position below the protective sleeve 230, that is, when the lower end of the protective sleeve 230 is inserted into the injection tube, the injection needle 220 can continue to pass through the tapered channel in the heat spreader body into the chamber in the body to directly inject water into the chamber. Since the protective sleeve 230 does not need to follow the injection needle 220 to pass through the tapered channel in the heat spreader body, the outer diameter of the protective sleeve 230 can be set to be larger than the inner diameter of the tapered channel and close to the inner diameter of the injection tube, that is, the protective sleeve 230 can be made relatively thicker and have better strength and rigidity, thereby improving the protection effect of the injection needle 220 against bending.

[0029] It is understandable that in order to better align the water injection assembly 200 with the liquid injection pipe of the heat plate when it descends, in some embodiments, reference is made to Figures 2 to 5 The water injection module also includes a guide component 400, which is arranged at the lower side of the water injection component 200 and includes a guide tube 410. The guide tube 410 is sequentially provided with an upper guide hole 411 and a lower guide hole 412 in the vertical direction. The upper guide hole 411 and the lower guide hole 412 are both coaxially arranged with the injection needle 220. The upper guide hole 411 can allow the protective sleeve 230 and the injection needle 220 to penetrate. The diameter of the lower guide hole 412 is larger than the diameter of the upper guide hole 411 and is aligned with the heat spreader. The liquid injection tube on it is adapted; through the above structure, when the heat spreader comes under the guide assembly 400, the upper end of the liquid injection tube of the heat spreader can be first inserted into the lower guide hole 412, and then the water injection assembly 200 can be accurately inserted into the liquid injection tube inserted in the lower guide hole 412 when it descends, guided by the upper guide hole 411, thereby avoiding the problem that when the liquid injection tube is not accurately aligned with the liquid injection needle 220, the liquid injection needle 220 will pierce the heat spreader body and damage the heat spreader or damage the liquid injection needle 220.

[0030] It is understandable that, since the injection tube of some vapor chambers may be slightly bent, the upper end of the injection tube may be deflected to a certain extent, so that the upper end of the injection tube can smoothly and quickly penetrate into the lower guide hole 412, in one embodiment, referring to Figure 5 The guide assembly 400 also includes a guide sleeve 420 connected to the lower end of the guide tube 410. The lower end of the guide sleeve 420 is provided with a trumpet-shaped guide opening 421 which is small at the top and large at the bottom. The guide opening 421 is connected to the lower guide hole 412. Therefore, when the upper end of the injection tube is slightly deflected, under the guidance of the guide opening 421, the upper end of the injection tube will be able to automatically correct and smoothly penetrate into the lower guide hole 412.

[0031] It should be understood that in order to guide the deflected injection tube to pass through the lower guide hole 412, in some other embodiments, the lower end of the lower guide hole 412 can also be directly set to a trumpet shape that is small at the top and large at the bottom.

[0032] It can be understood that when the upper end of the injection tube is offset to a large extent, or when the heat spreader is not accurately positioned below the guide tube 410, it will be difficult to guide the upper end of the injection tube into the lower guide hole 412 through the guide port 421, and it will be impossible to subsequently inject ultrapure water or other working fluids into the heat spreader through the water injection assembly 200, and it is easy to cause defective products that are not injected with water to flow to the downstream process of the heat spreader production; therefore, in order to accurately identify whether the injection tube of the heat spreader is correctly inserted into the lower guide tube 410, in one embodiment, reference is made to Figure 5 The guide assembly 400 also includes an in-place detection member 430 arranged on the side of the guide tube 410, and the tube wall of the guide tube 410 is provided with a detection hole 413, the detection hole 413 is connected to the upper end of the lower guide hole 412, the in-place detection member 430 is opposite to the detection hole 413, and is used to detect whether the upper end of the liquid injection tube of the heat spreader reaches the upper end of the lower guide hole 412; and it should be understood that the in-place detection member 430 and the injection valve 210 are both electrically connected to the control system for controlling the injection module. When the in-place detection member 430 detects that the upper end of the liquid injection tube of the heat spreader has not reached the upper end of the lower guide hole 412, the control system will control the injection valve 210 to suspend the injection of ultrapure water and other working fluids this time, and can also control the relevant alarm device to sound an alarm to remind the staff that there is a water injection problem in the heat spreader.

[0033] It is understandable that in order to further reduce the risk of bending and deformation of the injection needle 220 during the water injection process, in some embodiments, reference is made to Figures 2 to 5 The guide assembly 400 further includes a bending detection member 440 disposed on the upper side of the guide tube 410 , and the bending detection member 440 is used to detect whether the protection sleeve 230 is bent. It should be understood that, similarly, the bending detection member 440 and the injection drive mechanism 300 are both electrically connected to the control system for controlling the injection module, and when the bending detection member 440 detects that the protective sleeve 230 begins to bend, the control system can control the injection drive mechanism 300 to stop driving the water injection assembly 200 to descend; when the bending detection member 440 detects that the portion of the protective sleeve 230 located on the upper side of the guide tube 410 begins to bend, it means that there are serious obstructions such as blockage inside the injection tube of the heat spreader, and thus the injection needle 220 may not be able to penetrate the injection tube. At this time, if the water injection assembly 200 continues to forcibly descend, not only is it easy to damage the lower end of the injection needle 220, but the protective sleeve 230 and the injection needle 220 also have the risk of bending and deforming due to pressure. Therefore, immediately stopping driving the water injection assembly 200 to descend when it is detected that the protective sleeve 230 begins to bend can effectively reduce the above risks.

[0034] It should be understood that in one embodiment, both the in-place detection member 430 and the bending detection member 440 are selected to adopt photoelectric sensors, and the photoelectric sensors include a transmitter and a receiver; wherein, the transmitter and the receiver in the in-place detection member 430 are respectively arranged on both sides of the guide tube 410, and the detection hole 413 simultaneously penetrates the tube wall of the guide tube 410 close to the transmitter and the tube wall close to the receiver, and when the injection tube is inserted into the upper end position of the lower guide hole 412, the receiver in the in-place detection member 430 will not be able to receive the detection light emitted by the transmitter, otherwise it will be able to receive it; similarly, the transmitter and the receiver in the bending detection member 440 are respectively arranged on both sides of the protective sleeve 230, when the protective sleeve 230 is bent, the receiver in the bending detection member 440 will be able to receive the detection light emitted by the transmitter, otherwise it will not be able to receive it.

[0035] It can be understood that, in order to drive the guide assembly 400 to be sleeved on the upper end of the liquid injection tube of the heat soaking plate through a single driver, and drive the liquid injection needle 220 and the protective sleeve 230 to penetrate into the liquid injection tube of the heat soaking plate, thereby simplifying the structure and reducing the cost, in some embodiments, reference is made to Figure 2 and Figure 3 The liquid injection drive mechanism 300 includes a primary lifting plate 310, a secondary lifting plate 320 and a lifting driver 330. The driving end of the lifting driver 330 is connected to the primary lifting plate 310 and is used to drive the primary lifting plate 310 to move in a vertical direction. The water injection component 200 is arranged on the primary lifting plate 310. The secondary lifting plate 320 is slidably connected to the primary lifting plate 310 in a vertical direction. The guide component 400 is arranged on the secondary lifting plate 320. Through the above structure, when the heat spreader comes under the guide tube 410, in the process of driving the first lifting plate 310 to descend by the lifting driver 330, the guide tube 410 in the guide assembly 400 can first be docked with the upper end of the injection tube, and after the upper end of the injection tube is inserted into the upper end of the lower guide hole 412, due to the obstruction of the injection tube, the guide assembly 400 and the secondary lifting plate 320 will not be able to continue to descend with the first lifting plate 310, so the secondary lifting plate 320 will slide upward equivalent to the first lifting plate 310, so that the secondary lifting plate 320 and the guide assembly 400 can remain in the position where they are socketed with the upper end of the injection tube, and the water injection assembly 200 that continues to descend with the first lifting plate 310 can continue to approach the heat spreader, and allow the protective sleeve 230 and the injection needle 220 to accurately penetrate into the injection tube of the heat spreader under the guidance of the upper guide hole 411.

[0036] It is understood that in some of these embodiments, reference Figure 2 and Figure 3, a counterweight block 321 is provided on the secondary lifting plate 320; during the descending process of the guide assembly 400, friction may be generated between the upper end of the injection tube and the hole wall of the lower guide hole 412, so that before the upper end of the injection tube is plugged into the position of the upper end of the lower guide hole 412, the guide assembly 400 and the secondary lifting plate 320 cannot continue to descend due to the action of the above-mentioned friction force, and the upper end of the injection tube cannot be normally plugged into the position of the upper end of the lower guide hole 412. Through the counterweight block 321, the weight of the counterweight block can be used to overcome the influence of the above-mentioned friction force, so that in the process of the lifting drive 330 driving the first-stage lifting plate 310 to move downward, the upper end of the injection tube can be ensured to be plugged into the position of the upper end of the lower guide hole 412.

[0037] In some of these embodiments, reference Figure 2 and Figure 3 , the water injection assembly 200 can be connected to the primary lifting plate 310 in a sliding manner in the vertical direction, and the primary lifting plate 310 is provided with a sliding detection member 311, which is located on one side of the water injection assembly 200 and is used to detect whether the water injection assembly 200 slides relative to the primary lifting plate 310. It should be understood that since the water injection assembly 200 is connected to the primary lifting plate 310 in a sliding manner in the vertical direction, when the water injection assembly 200 is obstructed in the process of following the primary lifting plate 310 to move downward, the water injection assembly 200 will slide upward relative to the primary lifting plate 310, thereby further reducing the risk of bending and deformation of the injection needle 220 and the protective sleeve 230; and by providing a sliding detection member 311 on the primary lifting plate 310 to detect the sliding of the water injection assembly 200 on the primary lifting plate 310, it is possible to judge whether the descending process of the water injection assembly 200 is obstructed by the detection result of the sliding detection member 311, that is, when relative sliding is detected, it indicates that the water injection assembly 200 is When the descending process is hindered and no relative sliding is detected, it means that the descending process of the water injection assembly 200 is normal. Therefore, the detection result of the sliding detection part 311 can also be used to determine whether the injection needle 220 and the protective sleeve 230 have finally penetrated into the injection tube of the heat spreader normally; similarly, the sliding detection part 311 is electrically connected to the control system for controlling the injection module, and when the sliding detection part 311 detects relative sliding, the control system will control the injection drive mechanism 300 to stop driving the water injection assembly 200 to descend, that is, control the lifting drive 330 to stop driving the first-level lifting plate 310 to move downward, so as to further reduce the risk of damaging the injection needle 220 and the protective sleeve 230.

[0038] It should be understood that referring to Figure 2 and Figure 3In one embodiment, in order to realize the sliding of the water injection assembly 200 on the first-level lifting plate 310, a first slide rail extending in the vertical direction is provided on the front of the first-level lifting plate 310, and a first slider slidably matched with the first slide rail is provided on the back of the injection valve 210; and in order to realize the sliding of the secondary lifting plate 320 on the first-level lifting plate 310, and at the same time, the secondary lifting plate 320 and the water injection assembly 200 can overlap in the height direction, so that the water injection module is more compact, a second slide rail extending in the vertical direction is provided on the back of the first-level lifting plate 310, and a second slider slidably matched with the second slide rail is provided on the side of the secondary lifting plate 320 facing the first-level lifting plate 310, and the guide assembly 400 includes a connecting frame 450, and is connected to the bottom of the secondary lifting plate 320 through the connecting frame 450, and a part of the connecting frame 450 extends to the bottom of the water injection assembly 200, and the guide pipe 410, the in-place detection member 430 and the bending detection member 440 are all arranged on the connecting frame 450.

[0039] It can be understood that in one embodiment, the sliding detection member 311 is a contact switch, which is arranged on the upper side of the injection valve 210, and when the injection valve 210 slides upward relative to the first-level lifting plate 310, the injection valve 210 will abut against the proximity switch and be able to generate a corresponding detection signal.

[0040] It should be understood that, as mentioned above, the injection pipe of the vapor chamber may be skewed, and when the degree of deflection of the injection pipe is large, it will be difficult to make the upper end of the injection pipe pass through the lower guide hole 412; for this reason, in some embodiments, reference is made to Figure 1 The water injection module includes a clamping assembly 500, which is arranged at the lower side of the guide tube 410 and is used to fix the injection tube of the heat spreader. When the heat spreader comes to the bottom of the guide tube 410 and waits for injection, the injection tube of the heat spreader can be clamped and fixed by the clamping assembly 500 to preliminarily position the injection tube. Even if the degree of deflection of the injection tube is large, the clamping assembly 500 can be used to correct the injection tube to reduce the difficulty of the injection tube passing into the lower guide hole 412.

[0041] It should be understood that during the production and processing of the vapor chamber, the vapor chamber is carried on a carrying jig and transported through a conveyor line so that the vapor chamber carried on the carrying jig can pass through a plurality of different stations during the production and processing of the vapor chamber, for example, it can be transported to the water injection station below the water injection assembly 200 and the guide assembly 400 in the present invention. In order to prevent the clamping assembly 500 from affecting the transportation of the vapor chamber, in one embodiment, reference is made to Figure 6The clamping assembly 500 includes a transverse drive 510 and a clamping mechanism 520, wherein the clamping mechanism 520 is used to clamp the injection tube of the fixed heat spreader, and the transverse drive 510 is connected to the clamping mechanism 520, and can drive the clamping mechanism 520 to move horizontally between the conveyor line and the guide assembly 400, or drive the clamping mechanism 520 to move out from above the conveyor line; so that when the heat spreader is transported to the water injection station to wait for water injection, the transverse drive 510 will drive the clamping mechanism 520 to move between the conveyor line and the guide assembly 400, so as to clamp the injection tube of the heat spreader to position the injection tube, and after the water injection is completed, the clamping mechanism 520 will release the clamping of the injection tube, and the transverse drive 510 will drive the clamping mechanism 520 to move out from above the conveyor line, so that the heat spreader can continue to be transported along the conveyor line following the supporting fixture.
