Description

Technical Field

[0001] The present application relates to the technical field of thermal conductive gasket feeding, and in particular to a thermal conductive gasket feeding device and a thermal conductive gasket pasting device. Background Art

[0002] Thermal pads are high-performance gap-filling, heat-conducting materials primarily used between electronic devices and heat sinks, as well as between electronic devices and product housings. Traditionally, thermal pads are applied manually. However, this process can easily lead to missing or incorrect placement, necessitating rework and resulting in low production efficiency.

[0003] To improve production efficiency and pass rate, existing technologies use machine lamination to replace manual labor. However, the thermal pad loading device for machine lamination uses a tray to load the pads. The tray can only hold a limited number of thermal pads at a time, requiring frequent loading, which is labor-intensive. Utility Model Content

[0004] In view of this, an embodiment of the present application provides a thermally conductive gasket feeding device and a thermally conductive gasket pasting device to solve the problem that the material tray of the existing thermally conductive gasket feeding device needs to be frequently loaded.

[0006] The thermal pad loading device provided by the present invention has the following beneficial effects: During loading, the thermal tape first tears off the isolation film as it passes through the first tensioning wheel. A peeling plate then peels the thermal pad at the front of the stage from the base film, allowing it to fall to the back of the stage for pickup by the suction assembly. Simultaneously, the base film passes through the perforations below the peeling plate and is wound onto the base film reel by the second tensioning wheel, allowing the base film to be collected. Compared to a tray, the thermal tape wound onto the loading reel can store more thermal pads, solving the problem of frequent tray loading in existing thermal pad loading devices, reducing labor intensity, and improving production efficiency.

[0007] In some embodiments, the thermally conductive gasket feeding device further includes an isolation film reel for winding an isolation film.

[0008] The beneficial effect of adopting the above technical solution is that the isolation film is wound by the isolation film reel to tear the isolation film off from the thermal pad, which can reduce labor intensity compared to manually tearing off the isolation film.

[0009] In some embodiments, a plurality of the first tensioning wheels are provided, wherein one of the first tensioning wheels constitutes the isolation film roll.

[0010] The beneficial effect of adopting the above technical solution is that one of the first tensioning wheels not only plays the role of tensioning the heat conducting belt, but also plays the role of winding the isolation film. In this way, there is no need to design an additional isolation film reel, which simplifies the structure and reduces costs.

[0011] In some embodiments, a plurality of second tensioning wheels are provided, and the thermal pad loading device further includes a swing bracket swingably mounted on the frame and a pressure wheel rotatably mounted on the swing bracket, wherein the pressure wheel is used to press the base film onto one of the second tensioning wheels.

[0012] The beneficial effect of adopting the above technical solution is: the base film is pressed against one of the second tensioning wheels by the pressure wheel to ensure the stability and accuracy of the base film winding.

[0013] In some embodiments, the thermal pad loading device also includes a fixed bracket fixed on the frame and a screw threadedly connected to the fixed bracket, the first end of the screw is connected to the swing bracket, and the second end of the screw is provided with an operating part for driving the screw to rotate.

[0014] The beneficial effects of adopting the above technical solution are: the screw is screwed through the operating part to drive the swing bracket to swing through the screw, thereby pressing the clamping wheel on the second tensioning wheel; since the screw can be adjusted steplessly, the degree of clamping of the clamping wheel can be effectively adjusted.

[0015] In some embodiments, the operating part is a hand wheel.

[0016] The beneficial effect of adopting the above technical solution is that the screw is rotated by turning the hand wheel, which is conducive to the rotation of the screw.

[0017] In some embodiments, the thermally conductive pads are arranged in an array and are rectangular in shape, and the gap between two adjacent thermally conductive pads is 0-0.5 mm.

[0018] The beneficial effects of adopting the above technical solution are as follows: the gap between two adjacent thermally conductive pads is small, and can be completed by cutting with one knife, thereby improving production efficiency, reducing waste and lowering costs.

[0019] In some embodiments, in the width direction of the thermally conductive belt, the distance between the edge of the thermally conductive pad and the edge of the base film is not less than 5 mm.

[0020] The beneficial effect of adopting the above technical solution is: even if the edge of the thermal conductive tape is bumped during transportation, it will not affect the internal thermal conductive gasket, ensuring that the thermal conductive gasket can be used normally.

[0021] In some embodiments, a release layer is provided on the rear portion of the table and / or the release sheet.

[0022] The beneficial effect of adopting the above technical solution is: preventing the thermal pad from sticking to the back of the table and / or the peeling plate, which is conducive to the absorption of the thermal pad.

[0023] A second aspect of the present application provides a thermally conductive gasket pasting device, which includes the thermally conductive gasket feeding device as described in the first aspect.

[0024] The thermally conductive gasket pasting device adopts any one or more embodiments of the above-mentioned thermally conductive gasket feeding device, and thus has the beneficial effects of the above-mentioned embodiments, which will not be described in detail here.

[0049] The embodiment of the first aspect of the present application provides a thermal pad feeding device. Figure 1 and Figure 3 The thermal pad feeding device 10 includes a frame 11, a feeding reel 12, a first tensioning wheel 13, a support platform 14, a second tensioning wheel 15 and a bottom film reel 16. The feeding reel 12 and the first tensioning wheel 13 are respectively rotatably mounted on the frame 11. A heat-conducting tape 17 is wound on the feeding reel 12. The heat-conducting tape 17 is fed to the support platform 14 through the first tensioning wheel 13. The heat-conducting tape 17 includes a bottom film 173, an isolation film 171 and a plurality of thermal pads 172. The plurality of thermal pads 172 are arranged between the bottom film 173 and the isolation film 171. The support platform 14 includes a platform body 141 and a peeling plate 142. The peeling plate 142 is fixed on the table body 141 and divides the table body 141 into a front part 141a and a rear part 141b. The peeling plate 142 is used to peel the thermal pad 172 of the front part 141a from the bottom film 173, and make the thermal pad 172 fall to the rear part 141b through the peeling plate 142; the table body 141 has a through hole 143 below the peeling plate 142, and the second tensioning wheel 15 and the bottom film roll 16 are respectively rotatably installed on the frame 11, and the bottom film 173 passes through the through hole 143 from the bottom of the peeling plate 142 and is wound on the bottom film roll 16 through the second tensioning wheel 15.

[0050] The feeding reel 12 is rotatably mounted on the frame 11, that is, the feeding reel 12 rotates on the frame 11, so that the heat conducting tape 17 wound on the feeding reel 12 is unwound and fed to the support platform 14. The feeding reel 12 can be an active component or a driven component.

[0051] The first tensioning wheel 13 is rotatably mounted on the frame 11. While ensuring that the heat conducting belt 17 is tensioned, the friction between the first tensioning wheel 13 and the heat conducting belt 17 is reduced, thereby facilitating the conveyance of the heat conducting belt 17 toward the support platform 14. The number of the first tensioning wheel 13 can be one or more, and the first tensioning wheel 13 can be either an active component or a passive component.

[0052] The heat conducting belt 17 is fed to the support platform 14 through the first tensioning wheel 13 . It can be understood that after being unfolded, the heat conducting belt 17 passes through one or more first tensioning wheels 13 and is fed to the support platform 14 .

[0053] A plurality of thermally conductive gaskets 172 are provided between the base film 173 and the isolation film 171 . It is understood that the plurality of thermally conductive gaskets 172 can be arranged in an array between the base film 173 and the isolation film 171 , or can be arranged in a disordered manner between the base film 173 and the isolation film 171 .

[0054] Optionally, the bottom film 173 may be made of PET and may have a thickness of 0.05-0.07 mm.

[0055] Optionally, the thermally conductive gasket 172 is a thermally conductive silicone gasket, which is a thermally conductive material synthesized by a special process using silicone as a base material and adding various auxiliary materials such as metal oxides. The thickness of the thermally conductive gasket 172 can be set as needed.

[0056] The present application does not limit the manner in which the stripping plate 142 is fixed to the table body 141 . For example, the stripping plate 142 can be fixed to the table body 141 by welding, fastener connection, snap connection, crimping, interference connection, or the like.

[0057] The peeling plate 142 divides the table body 141 into a table front portion 141a and a table rear portion 141b. Optionally, the upper surface of the table front portion 141a is flat, so that the peeling plate 142 can peel the thermal pad 172 from the base film 173; the upper surface of the table rear portion 141b is flat, so that the suction component can suck the thermal pad 172 away from the table rear portion 141b.

[0058] The peeling plate 142 has a peeling blade at one end close to the front portion 141 a , and the peeling plate 142 peels the thermal pad 172 from the base film 173 through the peeling blade.

[0059] The thermal pad 172 falls onto the table rear portion 141b via the peeling plate 142. It can be understood that after being peeled from the base film 173, the thermal pad 172 rests on the peeling plate 142 and, pushed by the subsequently peeled thermal pad 172, gradually moves toward the table rear portion 141b, ultimately landing on the table rear portion 141b. It should be noted that after the thermal pad 172 lands on the table rear portion 141b, the thermal pad loading device 10 stops operating. After the suction assembly has completely absorbed the thermal pad 172 that has landed on the table rear portion 141b, the thermal pad loading device 10 resumes operation, and this cycle repeats.

[0060] The stage body 141 has a through-hole 143 below the peeling plate 142 for the bottom film 173 to pass through. The length of the through-hole 143 matches the width of the bottom film 173. While ensuring that the bottom film 173 can pass through, the through-hole 143 can also limit the bottom film 173 in its width direction, preventing the bottom film 173 from deviating from the preset position.

[0061] The second tensioning wheel 15 is rotatably mounted on the frame 11. While ensuring that the heat conducting belt 17 is tensioned, the friction between the second tensioning wheel 15 and the heat conducting belt 17 is reduced, thereby facilitating the conveyance of the heat conducting belt 17 to the base film reel 16. There may be one or more second tensioning wheels 15, and the second tensioning wheel 15 may be an active component or a passive component.

[0062] The bottom film reel 16 is rotatably mounted on the frame 11 , and the bottom film reel 16 is driven to rotate by the first driving device, that is, the bottom film reel 16 is an active component.

[0063] The thermal pad loading device 10 provided by the embodiment of the present application has the following beneficial effects: During loading, the thermal conductive tape 17 can first tear off the isolation film 171 while passing through the first tensioning wheel 13. Then, the thermal conductive pad 172 on the front portion 141a of the stage can be peeled off from the base film 173 using the peeling plate 142, and the thermal conductive pad 172 can be dropped to the back portion 141b of the stage via the peeling plate 142 to be picked up by the suction assembly. Simultaneously, the base film 173 passes from below the peeling plate 142 through the perforations 143 and is wound around the base film reel 16 by the second tensioning wheel 15, thereby collecting the base film 173. Compared to a tray, the thermal conductive tape 17 wound on the loading reel 12 can store more thermal conductive pads 172, solving the problem of frequent tray loading in the existing thermal conductive pad loading device 10, reducing labor intensity, and improving production efficiency.

[0064] Please refer to Figure 2 In some embodiments, the thermal pad feeding device 10 further includes an isolation film reel 18 for winding the isolation film 171 .

[0065] The isolation film reel 18 is rotatably mounted on the frame 11 , and the isolation film reel 18 is driven to rotate by the second driving device, that is, the isolation film reel 18 is an active component.

[0066] The isolation film 171 is wound up by the isolation film roll 18 so as to be torn off from the thermal pad 172 , thereby reducing labor intensity.

[0067] In other embodiments, the isolation film roll 18 may not be provided, and the isolation film 171 may be torn off manually.

[0068] Please refer to Figure 1 In some embodiments, a plurality of first tensioning wheels 13 are provided, wherein one first tensioning wheel 13 constitutes an isolation film roll 18 .

[0069] Optionally, three first tensioning wheels 13 are provided, and the middle first tensioning wheel 13 constitutes the isolation film reel 18. At this time, the middle first tensioning wheel 13 is driven to rotate by the third driving device, that is, the middle first tensioning wheel 13 is an active component.

[0070] By adopting the above technical solution, one of the first tensioning pulleys 13 not only tensions the heat conducting belt 17 but also winds the separator film 171. This eliminates the need for a separate separator film reel 18, simplifies the structure, and reduces costs. Furthermore, as more separator film 171 is wound around the first tensioning pulley 13, its diameter increases, further enhancing the tensioning effect of the first tensioning pulley 13.

[0071] Please refer to Figure 1In some embodiments, a plurality of second tensioning wheels 15 are provided, and the thermal pad loading device 10 further includes a swing bracket 111 swingably mounted on the frame 11 and a pressure wheel 112 rotatably mounted on the swing bracket 111, and the pressure wheel 112 is used to press the bottom film 173 onto one of the second tensioning wheels 15.

[0072] The pressing wheel 112 is a rubber wheel, which ensures that the bottom film 173 is pressed tightly against the second tensioning wheel 15 while avoiding damage to the bottom film 173 and realizing the recycling of the bottom film 173.

[0073] The bottom film 173 is pressed against one of the second tensioning wheels 15 by the pressure wheel 112 to ensure the stability and accuracy of the winding of the bottom film 173 .

[0074] In some embodiments, the thermal pad loading device 10 also includes a fixed bracket 113 fixed on the frame 11 and a screw 114 threadedly connected to the fixed bracket 113, the first end of the screw 114 is connected to the swing bracket 111, and the second end of the screw 114 is provided with an operating part 115 for driving the screw 114 to rotate.

[0075] Optionally, a threaded hole is provided on the fixing bracket 113 , and the screw 114 is screwed into the threaded hole.

[0076] The first end of the screw rod 114 is connected to the swing bracket 111 . It can be understood that the first end of the screw rod 114 can be hinged to the swing bracket 111 or can abut against the swing bracket 111 .

[0077] The operating portion 115 is manually rotated to rotate the screw rod 114 , thereby driving the swing bracket 111 to swing using the first end of the screw rod 114 .

[0078] The screw 114 is screwed through the operating part 115 to drive the swing bracket 111 to swing through the screw 114, thereby pressing the clamping wheel 112 onto the second tensioning wheel 15; since the screw 114 can be adjusted steplessly, the degree of compression of the clamping wheel 112 can be effectively adjusted.

[0079] In other embodiments, the fixed bracket 113 , the screw rod 114 and the operating portion 115 may not be provided, and the fourth driving device may be directly used to drive the swing shaft of the swing bracket 111 to rotate, so as to achieve the swing of the swing bracket 111 .

[0080] Please refer to Figure 1 In some embodiments, the operating portion 115 is a hand wheel.

[0081] It is understandable that the handwheel can be fixed to the second end of the screw rod 114 by welding, fastener connection, clamping, interference connection, threaded connection, etc.

[0082] The screw rod 114 is rotated by turning the hand wheel, which facilitates the rotation of the screw rod 114 .

[0083] In other embodiments, the operating portion 115 may also be an operating rod, which is perpendicular to the screw rod 114, wherein the operating rod may be fixed to the second end of the screw rod 114 by welding, fastener connection, clamping, interference connection, threaded connection, etc.

[0084] Please refer to Figure 4 In some embodiments, the thermally conductive pads 172 are arranged in an array and are rectangular in shape, and the gap a between two adjacent thermally conductive pads 172 is 0-0.5 mm.

[0085] The thermally conductive pads 172 are arranged in an array, that is, the thermally conductive pads 172 can be arranged in one row, two rows, three rows, or four rows in the width direction X. The width direction X is perpendicular to the feeding direction.

[0086] Optionally, the gap a between two adjacent thermal pads 172 may be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, etc.

[0087] The gap between two adjacent thermal pads 172 is small, and can be completed with one cut, which improves production efficiency, reduces waste, and reduces costs. The size of the gap a is determined by the thickness of the blade. The thicker the blade, the larger the gap a, and the thinner the blade, the smaller the gap a.

[0088] It should be noted that, while ensuring that the thermal pad 172 is completely cut off and not adhered, the base film 173 must not be cut to avoid breakage of the base film 173 or failure in stripping.

[0089] In other embodiments, the gap a between two adjacent thermally conductive gaskets 172 may be approximately 2 mm. In this case, the gap between two adjacent thermally conductive gaskets 172 is relatively large and requires two cuts to complete.

[0090] Please refer to Figure 4 In some embodiments, in the width direction X of the thermal conductive tape 17 , the distance d between the edge of the thermal conductive pad 172 and the edge of the bottom film 173 is not less than 5 mm.

[0091] Optionally, the distance d between the edge of the thermally conductive gasket 172 and the edge of the bottom film 173 may be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.

[0092] By adopting the above technical solution, even if the edge of the heat-conducting belt 17 is bumped during transportation, it will not affect the internal heat-conducting gasket 172, ensuring that the heat-conducting gasket 172 can be used normally.

[0093] In other embodiments, while ensuring that the thermal conductive tape 17 is not bumped, the distance d between the edge of the thermal conductive gasket 172 and the edge of the bottom film 173 can be less than 5 mm, for example, 4 mm, 3 mm, etc.

[0094] In some embodiments, a release layer is provided on the table rear portion 141 b and the peeling plate 142 .

[0095] Optionally, the anti-sticking layer is anti-sticking silica gel. Of course, the anti-sticking layer can also adopt other anti-sticking materials.

[0096] By adopting the above technical solution, the thermal conductive pad 172 is prevented from sticking to the table rear portion 141 b and the peeling plate 142 , which is conducive to the absorption of the thermal conductive pad 172 .

[0097] In other embodiments, since the adhesive force of the thermal pad 172 is relatively small, an anti-sticking layer may not be provided on the table rear portion 141b and the peeling plate 142; or, an anti-sticking layer may be provided only on the table rear portion 141b, and no anti-sticking layer may be provided on the peeling plate 142; or, an anti-sticking layer may be provided only on the peeling plate 142, and no anti-sticking layer may be provided on the table rear portion 141b.

[0098] The second aspect of the present application provides a thermally conductive pad pasting device, which includes the thermally conductive pad feeding device 10 of the first aspect.

[0099] The thermal pad pasting equipment has a high degree of automation, saving a workstation and a worker, with high production efficiency, outputting more than 2,000 PCS per hour, and the machine pasting is more precise and of higher quality.

[0100] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
