Description

Technical Field

[0001] The invention relates to the technical field of vapor chamber manufacturing equipment, and in particular to a degasser. Background Art

[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. Therefore, during the processing of the heat spreader, water or other working fluids need to be injected into the heat spreader through the injection tube on the heat spreader. After the water injection is completed, the air in the heat spreader needs to be extracted to complete the degassing, and then the injection tube needs to be squeezed and sealed. In the related art, the degassing and sealing of the heat spreader are achieved by a degasser, and the degasser is provided with a sealing mechanism. The sealing mechanism achieves sealing by squeezing and clamping the injection tube on the heat spreader through a clamp block. However, during the sealing process, the copper injection tube will extend from the pressure point to both ends due to pressure, and the injection tube will transmit extrusion force to the main body of the heat spreader. For the ultra-thin heat spreader, since the main body is very thin, it may be damaged by the extrusion force transmitted by the injection tube. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a degasser, which can effectively improve the damage problem of the vapor chamber caused by the injection tube squeezing the main body during sealing, thereby facilitating the improvement of the yield rate of the vapor chamber production process.

[0004] According to an embodiment of the present invention, the degassing machine includes a conveying device, a lifting and clamping device, a degassing device and a sealing device. The conveying device includes a conveying line and a carrying jig. The conveying line is provided with a degassing station and is used to convey the carrying jig. The carrying jig is used to carry a heat spreader. The lifting and clamping device is arranged at one side of the degassing station, and includes a clamping mechanism and a lifting mechanism. The clamping mechanism is used to clamp the liquid injection pipe of the heat spreader conveyed to the degassing station along with the carrying jig. The lifting mechanism is connected to the clamping mechanism and is used to drive the clamping mechanism to carry the heat spreader up so that the heat spreader is out of contact with the carrying jig. The degassing device includes a degassing component arranged above the degassing station, and the degassing component can be connected with the upper end of the liquid injection pipe of the heat spreader after lifting to degas the heat spreader. The sealing device is arranged below the degassing component and is used to squeeze the liquid injection pipe of the heat spreader after lifting to achieve the sealing of the heat spreader.

[0005] The degasser according to the embodiment of the present invention has at least the following beneficial effects: Before degassing, the degassing machine of the present embodiment can first clamp the liquid injection tube of the heat spreader by means of the lifting and clamping device, and lift the heat spreader so as to separate the heat spreader from the carrier jig used for transporting it. In addition, during the subsequent processes in which the degassing device and the sealing device respectively degas and seal the heat spreader, the heat spreader can be kept separated from the carrier jig, that is, the heat spreader is in a state where the main body is suspended. Therefore, during the sealing process, when the liquid injection tube is extended due to extrusion, the main body of the heat spreader can move downward along with the extension of the lower end of the liquid injection tube, thereby preventing the liquid injection tube from applying extrusion force to the main body of the heat spreader. Therefore, damage to the main body of the heat spreader due to extrusion by the liquid injection tube can be avoided, which is beneficial to improving the yield rate of heat spreader production.

[0022] The following is the attached Figure 1 To Attachment Figure 8 , describing the degasser of some embodiments of the present invention.

[0023] Reference Figure 1 and Figure 3According to some embodiments of the present invention, the degassing machine includes a conveying device 2000 for conveying the vapor chamber 10 and a degassing unit 1000 for degassing and sealing the vapor chamber 10; wherein the conveying device 2000 includes a conveying line 700 and a carrying fixture 900, the carrying fixture 900 is used to carry the vapor chamber 10, and the conveying line 700 is used to convey the carrying fixture 900, and the conveying line 700 is provided with a degassing station, and can convey the carrying fixture 900 and the vapor chamber 10 to the degassing station together; the degassing unit 1000 is arranged corresponding to the degassing station, and includes a lifting clamping device 100, a degassing device 200 and a sealing device 500; wherein the lifting clamping device 100 is arranged on one side of the degassing station, and includes a clamping mechanism 110 and a lifting mechanism 120. When the carrying fixture 900 carries the vapor chamber 10 to the degassing station, the clamping mechanism The structure 110 can clamp the injection tube 11 of the heat spreader 10 on the degassing station, and the lifting mechanism 120 is connected to the clamping mechanism 110 and is used to drive the clamping mechanism 110 to carry the heat spreader 10 up, so that the heat spreader 10 is out of contact with the supporting fixture 900, and the main body 12 of the heat spreader 10 is suspended in the air; the degassing device 200 includes a degassing component 300 arranged above the degassing station, and the degassing component 300 is used to dock with the upper end of the injection tube 11 of the heat spreader 10 after lifting to degas the heat spreader 10; the sealing device 500 is arranged below the degassing component 300, and the height is located at a position corresponding to the injection tube 11, so that after the degassing component 300 completes the degassing of the heat spreader 10 after lifting, the sealing mechanism 510 can squeeze the injection tube 11 of the heat spreader 10 after lifting to achieve the sealing of the heat spreader 10, so as to prevent air from entering the heat spreader 10 again.

[0024] It should be understood that, before degassing, the degassing machine of the present embodiment can first clamp the injection tube 11 of the heat spreader 10 through the lifting and clamping device 100, and lift the heat spreader 10, so that the heat spreader 10 is out of contact with the supporting fixture 900 that carries it for transportation, and in the subsequent process of the degassing device 200 and the sealing device 500 respectively performing degassing and sealing on the heat spreader 10, the heat spreader 10 can be kept out of contact with the supporting fixture 900, that is, the heat spreader 10 is in a state where the main body 12 is suspended. Therefore, during the sealing process, when the injection tube 11 is extended due to extrusion, the main body 12 of the heat spreader 10 can move downward along with the extension of the lower end of the injection tube 11, thereby preventing the injection tube 11 from applying an extrusion force to the main body 12 of the heat spreader 10. Therefore, damage to the main body 12 of the heat spreader 10 due to extrusion by the injection tube 11 can be avoided, which is beneficial to improving the yield rate of the heat spreader 10 production.

[0025] It is understandable that in order to enable the degassing assembly 300 to dock with the upper end of the liquid injection pipe 11 of the heat plate 10, refer to Figure 4In one embodiment, the degassing device 200 also includes a lifting drive mechanism 400, and the lifting drive mechanism 400 includes a lifting frame 410 and a lifting driver 420, wherein the lifting frame 410 is connected to the driving end of the lifting driver 420 and can be lifted and lowered under the drive of the lifting driver 420, and the degassing component 300 is arranged on the lifting frame 410, so that the degassing component 300 can be lifted and lowered together with the lifting frame 410, and when the degassing component 300 descends, it can approach the upper end of the injection pipe 11 of the heat spreader 10 that has been lifted and dock with it.

[0026] It is understandable that in order to prevent the outside air from entering the heat spreader 10 again during the degassing process, the degassing component 300 is provided with a sealing structure for cooperating with the upper end of the liquid injection tube 11 of the heat spreader 10 for sealing, and considering that the liquid injection tube 11 will not only extend downward at the lower end during the sealing process, but also extend upward at the upper end of the liquid injection tube 11, so as to avoid friction between the upper end of the liquid injection tube 11 and the sealing structure during the upward extension process, thereby damaging the seal in the sealing structure, in one embodiment, refer to Figures 4 to 7 The degassing assembly 300 can be slidably connected to the lifting frame 410 in the vertical direction, and includes an air intake pipe 310 and a compression sealing mechanism; the air intake pipe 310 is provided with an air intake hole 311 and a sealing cavity 312, the sealing cavity 312 is provided at the lower end of the air intake pipe 310, and is used to install a sealing structure docking with the upper end of the injection pipe 11, the lower end of the air intake hole 311 is connected to the sealing cavity 312, and the upper end of the air intake hole 311 extends to the top of the air intake pipe 310 and is used to connect to the vacuum generating device; wherein the sealing structure includes an elastic sealing sleeve 350, and the elastic sealing sleeve 350 is installed in the sealing cavity 312, and a through first center hole 351 is formed in the middle, and the elastic sealing sleeve 350 can pass through the first center hole 351. The center hole 351 is sleeved on the upper end of the injection tube 11 of the heat spreader 10, and the upper end of the first center hole 351 is connected to the suction hole 311, so that the air in the heat spreader 10 can flow to the vacuum generating device (not shown in the drawings) through the first center hole 351 and the suction hole 311 in sequence; the compression sealing mechanism is connected to the elastic sealing sleeve 350, and can axially squeeze the elastic sealing sleeve 350, so that the elastic sealing sleeve 350 can be deformed due to pressure, thereby shrinking the aperture of the first center hole 351, and the elastic sealing sleeve 350 can hold the injection tube 11 of the heat spreader 10 passing through the first center hole 351, thereby preventing outside air from entering the heat spreader 10 from the upper end of the injection tube 11.

[0027] It should be understood that, through the above structure, when the lifting drive mechanism 400 drives the degassing component 300 to move downward, the degassing component 300 will be sleeved on the upper end of the injection tube 11 of the jacked heat spreader 10 through the first center hole 351 in the elastic sealing sleeve 350, and then the elastic sealing sleeve 350 will be radially squeezed by the compression sealing mechanism to deform the elastic sealing sleeve 350 and shrink the aperture of the first center hole 351, so that the inner wall of the elastic sealing sleeve 350 is squeezed and fits the injection tube 11 passing through the first center hole 351, thereby avoiding a gap between the inner wall of the elastic sealing sleeve 350 and the upper end of the injection tube 11, so as to avoid external air The gas enters the heat spreader 10 from the upper end of the liquid injection tube 11; and when the heat spreader 10 is sealed, since the degassing component 300 is slidably connected to the lifting frame 410 in the vertical direction, when the upper end of the liquid injection tube 11 moves upward due to being squeezed, the elastic sealing sleeve 350 will be able to push the entire degassing component 300 to slide upward along with the extension of the upper end of the liquid injection tube 11, thereby avoiding relative sliding and friction between the upper end of the liquid injection tube 11 and the elastic sealing sleeve 350, and thus effectively reducing the wear problem of the sealing structure, which is beneficial to improving the degassing effect during the production process of the heat spreader 10 and improving the yield rate of the heat spreader 10 production.

[0028] It is understandable that, since the elastic sealing sleeve 350 is disposed in the sealing cavity 312, in order to facilitate the connection and extrusion of the elastic sealing sleeve 350 located in the sealing cavity 312, in some embodiments, reference is made to Figures 4 to 7 The compression sealing mechanism includes a compression ring 320 and a compression driver. The upper end of the compression ring 320 is inserted into the sealing cavity 312, and the lower end of the compression ring 320 is located outside the intake pipe 310. The compression driver is connected to the part of the compression ring 320 located outside the sealing cavity 312, that is, connected to the lower end of the compression ring 320, and is used to drive the compression ring 320 to axially compress the elastic sealing sleeve 350; at the same time, in order to prevent the compression ring 320 from affecting the upper end of the injection tube 11 of the heat spreader 10 from penetrating into the elastic sealing sleeve 350, the compression ring 320 is provided with a second center hole 321 opposite to and through the first center hole 351, and the inner diameter of the second center hole 321 can allow the injection tube 11 of the heat spreader 10 to pass through.

[0029] It can be understood that in order to reduce the size of the degassing assembly 300 in the vertical direction so as to make the structure of the degassing assembly 300 more compact, in some embodiments, referring to Figures 4 to 7The clamping driver includes a clamping cylinder 330 and a pressure cap 340. The piston rod of the clamping cylinder 330 is hollow, the air intake pipe 310 is passed through the piston rod, the pressure cap 340 is connected to the lower end of the piston rod and is opposite to the pressure ring 320, so that the air intake pipe 310, the elastic sealing sleeve 350 and the pressure ring 320 can overlap with the clamping driver in the height direction, thereby reducing the volume size of the degassing component 300 in the height direction.

[0030] It should be understood that, through the above structure, when the piston rod retracts and drives the pressure cap 340 upward to approach the elastic sealing sleeve 350, the pressure cap 340 will be able to abut and squeeze the pressure ring 320, so that the pressure ring 320 moves upward with the pressure cap 340, and then the pressure ring 320 axially squeezes the elastic sealing sleeve 350, and when the piston rod extends and drives the pressure cap 340 to move downward, the pressure cap 340 will be away from the elastic sealing sleeve 350, so that the elastic sealing sleeve 350 can recover under its own elastic force and push the pressure ring 320 to move downward with the pressure cap 340. Similarly, in order to prevent the pressure cap 340 from affecting the upper end of the heat spreader 10 from penetrating into the elastic sealing sleeve 350, the pressure cap 340 is provided with a third center hole 341 opposite to and through the second center hole 321, and the inner diameter of the third center hole 341 can allow the injection tube 11 of the heat spreader 10 to pass through.

[0031] It should be understood that since the injection tube 11 may be deflected to a certain extent, in order to enable the upper end of the injection tube 11 to better penetrate into the first center hole 351 through the third center hole 341 and the second center hole 321, in some embodiments, the lower end of the second center hole 321 and the third center hole 341 are both configured to be trumpet-shaped with a small upper part and a large lower part.

[0032] It is understood that in some of these embodiments, reference Figures 4 to 7 , the lifting drive mechanism 400 also includes a compression elastic member 430, which connects the lifting frame 410 and the degassing assembly 300 and is used to provide an elastic force to prevent the degassing assembly 300 from sliding upward. It should be understood that by providing the compression elastic member 430, when the degassing assembly 300 is driven by the lifting drive 420 to descend along with the lifting frame 410 and begins to dock with the injection pipe 11 of the heat spreader 10, the degassing assembly 300 can be prevented from sliding upward relative to the lifting frame 410 under the push of the injection pipe 11 (for example, under the friction between the injection pipe 11 and the elastic sealing sleeve 350), so that the degassing assembly 300 can be smoothly sleeved on the upper end of the injection pipe 11 through the elastic sealing sleeve 350, so as to better ensure the sealing performance during the degassing process and the sealing process.

[0033] It can be understood that in order to better ensure the degassing effect, the degassing component 300 includes a vacuum gauge 361, which is connected to the suction hole 311 and is used to detect the vacuum degree in the suction hole 311; it should be understood that since the suction hole 311 is connected to the first center hole 351 in the elastic sealing sleeve 350, by setting the vacuum gauge 361 to detect the vacuum degree in the suction hole 311, the sealing condition between the elastic sealing sleeve 350 and the upper end of the injection tube 11 can be understood, thereby avoiding the problem of unqualified degassing of the heat spreader 10 due to poor sealing.

[0034] It is understood that in some of these embodiments, reference Figures 4 to 7 The degassing unit 1000 further includes a vacuum tube 600, and the degassing assembly 300 includes a multi-way tube 370, wherein the multi-way tube 370 includes a first tube portion 371, a second tube portion 372, and a third tube portion 373 that are interconnected, and the first tube portion 371, the second tube portion 372, and the third tube portion 373 are respectively connected to the suction pipe 310, the vacuum gauge 361, and the vacuum tube 600, and the vacuum tube 600 is used to connect the vacuum generating device, so that the suction hole 311 in the suction pipe 310 can be connected to the vacuum gauge 361 and the external vacuum generating device at the same time by means of the multi-way tube 370. And, in some embodiments, refer to Figures 4 to 7 In order to facilitate disconnection of the connection between the degassing assembly 300 and the vacuum generating device, a switch valve 362 is provided between the third pipe portion 373 and the vacuum pipe 600 .

[0035] It should be understood that, in one embodiment, the switch valve 362 is selected to be an angle valve.

[0036] It should be understood that in order to achieve the sliding of the degassing assembly 300 on the lifting frame 410, in some embodiments, reference is made to Figures 4 to 7 The degassing component 300 includes a sliding seat 380, and a first sliding rail extending in a vertical direction is arranged on the lifting frame 410. A first sliding block slidably matched with the first sliding rail is arranged on the side of the sliding seat 380 facing the lifting frame 410, so that the degassing component 300 can be slidably connected to the lifting frame 410 through the sliding seat 380; and, in one embodiment, the clamping elastic member 430 is selected to adopt a heavy-loaded spring, and in order to enable the clamping elastic member 430 to provide an elastic force to prevent the degassing component 300 from sliding upward, the lower end of the clamping elastic member 430 is connected to the upper end of the sliding seat 380, and the upper end of the clamping elastic member 430 is connected to the lifting frame 410.

[0037] It should be understood that in some of these embodiments, reference Figure 4The sliding seat 380 is a bearing member in the degassing assembly 300, and the sliding seat 380 includes a seat body 381 and a clamping block 382, ​​the clamping block 382 is arranged on the seat body 381, and is used to clamp and fix the multi-way tube 370; and in order to facilitate the connection between the multi-way tube 370 and the switch valve 362, the vacuum gauge 361 and the suction pipe 310, the degassing assembly 300 also includes a pipe clamp 391 and a connecting pipe 392, wherein the vacuum gauge 361 is connected to the connecting pipe 392 through the pipe clamp 391, and the connecting pipe 392 is connected to the second pipe part 372 through the pipe clamp 391, and the suction pipe 310 and the angle valve are respectively connected to the first pipe part 371 and the third pipe part 373 through the pipe clamp 391.

[0038] It should be understood that in order to facilitate the installation and fixation of the clamping cylinder 330, in one embodiment, an internal threaded hole is provided at the top of the upper end of the cylinder body of the clamping cylinder 330, the suction pipe 310 is passed through the internal threaded hole, and an external threaded end is provided to cooperate with the internal thread in the internal threaded hole.

[0039] It is understandable that in order to prevent the clamping mechanism 110 from affecting the conveying of the carrying fixture 900 and the heat plate 10 on the conveying line 700, in some embodiments, reference is made to Figure 2 The lifting and clamping device 100 also includes a first transverse movement driver 130, which is connected to the clamping mechanism 110 and can drive the clamping mechanism 110 to move horizontally so that the clamping mechanism 110 can be moved to or out of the top of the degassing station; through the above structure, when the heat spreader 10 follows the supporting fixture 900 to be transported to the degassing station below the suction pipe 310, the first transverse movement driver 130 can drive the clamping mechanism 110 to move between the degassing station and the degassing component 300, so that the liquid injection pipe 11 of the heat spreader 10 can be clamped and positioned by the clamping mechanism 110, and after the heat spreader 10 on the supporting fixture 900 completes degassing, the clamping mechanism 110 can be moved out from between the degassing station and the degassing component 300, so that the supporting fixture 900 and the heat spreader 10 above it can continue to be transported downstream of the conveyor line 700.

[0040] And, similarly, in some embodiments, reference Figure 8The sealing device 500 includes a sealing mechanism 510 and a second transverse driving device 520. The sealing mechanism 510 is used to squeeze and seal the liquid injection pipe 11 of the heat soaking plate 10 located below the air intake pipe 310. The second transverse driving device 520 is connected to the sealing mechanism 510 and can drive the sealing mechanism 510 to move horizontally so that the sealing mechanism 510 moves to or out of the bottom of the air intake pipe 310. Through the above structure, when the heat soaking plate 10 follows the carrying fixture 900 to be transported to the bottom of the air intake pipe 310, the second transverse driving device 520 can be used to move the sealing mechanism 510 horizontally. 20 drives the sealing mechanism 510 to move to the bottom of the suction pipe 310, that is, to move to between the degassing station and the degassing component 300, and then the sealing mechanism 510 can clamp and seal the injection tube 11 of the heat spreader 10. After the heat spreader 10 on the supporting fixture 900 is sealed, the sealing mechanism 510 can be moved out from under the suction pipe 310, that is, from between the degassing station and the degassing component 300, so that the supporting fixture 900 and the heat spreader 10 on it can continue to be transported downstream of the conveyor line 700.

[0041] It should be understood that since the liquid injection tube 11 of the heat spreader 10 will extend to both ends during the sealing operation, in order to prevent the clamping mechanism 110 from affecting the extension of the liquid injection tube 11 to both ends and causing the liquid injection tube 11 to bend, it is necessary to keep the degassing assembly 300 sleeved on the upper end of the liquid injection tube 11 of the heat spreader 10, and first make the clamping mechanism 110 loosen the clamping of the liquid injection tube 11 and the first transverse movement driver 130 drive the clamping mechanism 110 to move out of the top of the degassing station, and then make the second transverse movement driver 520 drive the sealing mechanism 510 to move horizontally above the degassing station, and then seal the liquid injection tube 11 of the heat spreader 10.

[0042] It should be understood that in one embodiment, reference Figure 2 The lifting mechanism 120 and the first transverse movement driver 130 both use cylinders. For the sake of distinction, the two are named as the lifting cylinder and the first transverse movement cylinder respectively, wherein the first transverse movement cylinder is connected to the piston rod of the lifting cylinder, and the clamping mechanism 110 is connected to the piston rod of the first transverse movement cylinder, so that when the piston rod of the lifting cylinder is extended or retracted, the first transverse movement cylinder and the clamping mechanism 110 can be driven to rise and fall together, and when the piston rod of the first transverse movement cylinder is extended or retracted, the clamping mechanism 110 can be driven to move horizontally; and the clamping mechanism 110 includes a thumb cylinder 111 and two clamping blocks 112, the two clamping blocks 112 are respectively connected to the two thumbs of the thumb cylinder 111, and can be driven by the thumb cylinder 111 to approach each other to clamp or release the injection tube 11 of the heat spreader 10.

[0043] It is understood that in some of these embodiments, reference Figure 8The sealing mechanism 510 includes a sealing driver 512, a driving plate 513 and two extrusion blocks 515. The sealing driver 512 is connected to the driving plate 513 and is used to drive the driving plate 513 to slide along a first horizontal direction. The two extrusion blocks 515 are slidably arranged along a second horizontal direction. The driving plate 513 is provided with two sliding grooves 514 that are acutely angled with the first horizontal direction. The two sliding grooves 514 are symmetrically arranged. Two rollers 516 are respectively arranged on the two extrusion blocks 515. The two rollers 516 are respectively embedded in the two sliding grooves 514. The driving plate 513 can drive the two extrusion blocks 515 to move forward and backward through the cooperation of the two sliding grooves 514 and the two rollers 516. The pressing blocks 515 approach or move away from each other along the second horizontal direction; wherein, the first horizontal direction is parallel to the conveying direction of the conveyor line 700 at the degassing station, and the second horizontal direction is perpendicular to the conveying direction of the conveyor line 700 at the degassing station; it should be understood that, through the above structure, not only can the two extrusion blocks 515 be synchronously driven by a single sealing driver 512 to approach each other to clamp and extrude the injection tube 11 of the heat spreader 10, thereby achieving the sealing of the injection tube 11, but the driving force of the sealing driver 512 can also be amplified so that the extrusion force applied to the injection tube 11 by the two extrusion blocks 515 can be greater than the driving force of the sealing driver 512.

[0044] It is understandable that in order to facilitate monitoring of the squeezing force of the sealing mechanism 510 on the liquid injection tube 11 of the heat plate 10, thereby preventing the liquid injection tube 11 from being broken due to excessive squeezing, in some embodiments, reference is made to Figure 8 The sealing mechanism 510 also includes a pressure sensor 517, which is arranged between the driving end of the sealing driver 512 and the driving plate 513, and is used to detect the driving force applied by the sealing driver 512 to the driving plate 513 during the sealing process. The control module in the degasser can control the sealing driver 512 according to the pressure value detected by the pressure sensor 517. For example, when the pressure value detected by the pressure sensor 517 reaches a set value, the sealing driver 512 is controlled to stop pushing the driving plate 513 to prevent further squeezing of the injection tube 11.

[0045] It should be understood that in order to enable the second transverse drive 520 to push the sealing mechanism 510 to move to or out of the degassing station as a whole, in one embodiment, referring to Figure 8The sealing mechanism 510 includes a slide 511, a second slider is provided at the bottom of the slide 511, and is slidably connected to a second slide rail extending along the first horizontal direction by means of the second slider, and a sealing driver 512, a driving plate 513 and two extrusion blocks 515 are all arranged on the slide 511; and, in order to enable the two extrusion blocks 515 to slide horizontally along the second horizontal direction, a third slide rail extending along the second horizontal direction is provided at one end of the slide 511, and the two extrusion blocks 515 are slidably connected to the third slide rail, and the sealing driver 5 12 is connected to the other end of the slide 511 (the end opposite to the extrusion block 515), and the slide 511 is also provided with a fourth slide rail extending along the first horizontal direction, the fourth slide rail is located between the extrusion block 515 and the sealing driver 512, and the driving plate 513 is slidably connected to the fourth slide rail through the third slider at the bottom thereof; the driving end of the second transverse driving driver 520 is connected to the slide 511, and then drives the slide 511 to move along the first horizontal direction to drive the entire sealing mechanism 510 to move laterally to or out of the top of the degassing station.

[0046] It should be understood that, in one embodiment, the sealing drive 512 is selected to be a cylinder, and the second transverse drive 520 is selected to be a linear motor module.

[0047] It is understandable that in order to improve the efficiency of degassing and sealing, in some embodiments, reference is made to Figure 1 and Figure 2 The carrying jig 900 is provided with four fixing positions 910 in sequence along the conveying direction of the conveying line 700, and they are respectively the first fixing position, the second fixing position, the third fixing position and the fourth fixing position, and each fixing position is used to carry a heat spreader 10; there are two degassing stations, and each degassing station is correspondingly provided with two groups of degassing units 1000, that is, a total of four groups of degassing units 1000 are provided, and each group of degassing units 1000 is used to cooperate in completing the degassing and sealing of a heat spreader 10, so that the four heat spreaders 10 carried on the carrying jig 900 can be degassed and sealed in two batches in sequence. Furthermore, in order to arrange the heat spreader 10 on the supporting jig 900 relatively more densely and prevent the degassing units 1000 from interfering with each other when arranged along the conveyor line 700, the two degassing units 1000 corresponding to one degassing station are used to complete the degassing and sealing of the heat spreader 10 in the first fixed position and the third fixed position, and the two degassing units 1000 corresponding to the other degassing station are used to complete the degassing and sealing of the heat spreader 10 in the second fixed position and the fourth fixed position.

[0048] It is understandable that in order to facilitate the online use of multiple degassing machines to further improve the efficiency of degassing and sealing during the production of the vapor chamber 10, in some embodiments, reference is made to Figure 1The conveying device 2000 includes a first transfer mechanism 810 and a second transfer mechanism 820, the conveying line 700 includes a first conveying line 710 and a second conveying line 720 arranged in parallel, the degassing station is arranged on the second conveying line 720, the first transfer mechanism 810 is arranged at the head end of the first conveying line 710, and is used to transfer the carrying fixture 900 from the head end of the first conveying line 710 to the head end of the second conveying line 720, the second transfer mechanism 820 is arranged at the tail end of the first conveying line 710, and is used to transfer the carrying fixture 900 from the tail end of the second conveying line 720 to the tail end of the first conveying line 710; so that when multiple degassing machines are connected online, the first conveying lines 710 of the multiple degassing machines can be connected head to tail in sequence to form a continuous The main conveyor line 700 of the degasser, and the first transfer mechanism 810 in each degasser can transport the supporting jig 900 carrying the heat spreader 10 that has not been degassed on the main conveyor line to the corresponding second conveyor line 720, so that the supporting jig 900 carrying the heat spreader 10 that has not been degassed can be transported to the degassing station via the second conveyor line 720 for degassing and sealing. The supporting jig 900 transported to the end of the second conveyor line 720 and carrying the heat spreader 10 that has been degassed and sealed can be transferred back to the main conveyor line 700 by the corresponding second transfer mechanism 820, and can finally be output to the last degasser via the end of the main conveyor line (that is, the end of the last first conveyor line 710 arranged along the conveying direction).

[0049] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
