Description

Technical Field

[0001] This utility model relates to the field of coating devices, specifically to a stepped radiator thermal grease coating device. Background Technology

[0002] There are various types of radiators used in existing air conditioner electrical boxes, one of which is the stepped radiator. This type of radiator typically absorbs heat by contacting the heating element with its front side. Before assembly, a certain thickness of thermal grease needs to be printed onto the back of the stepped radiator inside the air conditioner electrical box. Its main function is to remove air or gaps on the back, maximizing heat conduction and significantly improving or ensuring heat dissipation performance. Therefore, the quality and effectiveness of the thermal grease printed on the stepped radiator must be strictly controlled.

[0003] The existing stepped heat sink assembly process is cumbersome, requiring one person to apply thermal grease to the heat sink twice, and another person to assemble the heat sink into the electrical box. During the assembly process, the heat sink is repeatedly exposed to the thermal grease, which often contaminates other parts of the product, resulting in poor appearance, low work efficiency, and uneven thermal grease thickness. In addition, there is a time difference between the two printing processes, and the thermal grease is prone to drying and solidification during the printing process, which leads to a decrease or even loss of the heat dissipation performance of the thermal grease. Utility Model Content

[0004] The primary objective of this invention is to provide a stepped radiator thermal grease coating device that offers high coating efficiency, ensures coating quality, and facilitates quick workpiece removal by operators.

[0005] The second objective of this invention is to provide another stepped radiator thermal grease coating device that offers high coating efficiency, ensures coating quality, and facilitates quick workpiece removal by operators.

[0006] To achieve the aforementioned first objective, this utility model provides a stepped radiator thermal grease coating device, comprising: a radiator positioning module, which includes a positioning base and a support block, wherein the positioning base is provided with a radiator positioning groove, and the support block is disposed on one side of the positioning base; a thermal grease coating module, which is hinged to the support block via a hinge shaft, and includes a coating mesh assembly capable of covering the radiator positioning groove above; the coating mesh assembly includes a first coating mesh sheet, a connector, and a second coating mesh sheet arranged sequentially along a first direction, wherein the first coating mesh sheet is higher than the second coating mesh sheet, and the connector is provided with a guide wall, which is inclined downwards from the end near the first coating mesh sheet to the end near the second coating mesh sheet in the first direction; the center of gravity of the thermal grease coating module is located on the side of the hinge shaft away from the radiator positioning groove.

[0007] As can be seen from the above scheme, during use, the radiator can be directly placed into the radiator positioning slot, and then the thermal grease coating module is pressed down. The grease is then coated in one go from bottom to top along the first direction using a scraper, so that the thermal grease is evenly coated on the surface of the radiator, ensuring coating quality and improving work efficiency. After completion, the thermal grease coating module is released. By setting the center of gravity of the thermal grease coating module on the side away from the radiator positioning slot of the hinge, the thermal grease coating module becomes a non-powered device. When released, it automatically tilts backward, and the coating mesh assembly moves away from the radiator, leaving space for the operator to pick up the workpiece. The operator can then directly take out the radiator with the thermal grease coated and place it in the electrical box for assembly with the outdoor unit motherboard.

[0008] This stepped radiator thermal grease coating device simplifies the existing complex and cumbersome operation method, eliminates the drawbacks of the current practice, improves work efficiency, and avoids the thermal grease from contaminating other parts of the product, which could lead to abnormal product quality. It also avoids the problem of uneven thermal grease thickness and the time difference between the two printing processes, which can cause the thermal grease to dry out and harden during the printing process. The stepped radiator thermal grease coating device provided by this utility model can also ensure the heat dissipation performance of the thermal grease, thereby ensuring product quality.

[0009] In a preferred embodiment, the coated mesh assembly further includes a mesh mounting frame with a receiving groove, wherein the first coated mesh, the connector, and the second coated mesh form the bottom wall of the receiving groove.

[0010] Therefore, the receiving tank is used to hold the thermal grease, which can limit the position and size of the coated area and prevent the thermal grease from contaminating other parts of the product. At the same time, the mesh mounting frame is used to position each coated mesh and connector.

[0011] A further embodiment is that the thermal grease coating module also includes a first frame positioning block, a second frame positioning block, and a connecting block; the first frame positioning block and the second frame positioning block are arranged along a second direction and both extend along a first direction; the coating mesh assembly is fixed between the first frame positioning block and the second frame positioning block and is disposed near the first end of the thermal grease coating module; the connecting block is disposed at the second end of the thermal grease coating module; in the first direction, the hinge shaft is located between the coating mesh assembly and the connecting block.

[0012] As can be seen, the first frame positioning block, the second frame positioning block, and the connecting block are fixedly connected to form a fixed frame for the coating mesh assembly, which is used to support and position the coating mesh assembly.

[0013] A further embodiment is that the hinge shaft passes sequentially through the first frame positioning block and the second frame positioning block along the second direction; the thermal grease coating module also includes a first width limiter and a second width limiter, both of which are disposed on the hinge shaft and located between the first frame positioning block and the second frame positioning block. The first width limiter engages with the first frame positioning block in the second direction, and the second width limiter engages with the second frame positioning block in the second direction.

[0014] Therefore, by setting the width limiter, the width between the first frame positioning block and the second frame positioning block can be limited and adjusted.

[0015] A further embodiment is that both the first frame positioning block and the second frame positioning block are provided with mesh position adjustment holes, which extend along the first direction. The mesh mounting frame is provided with frame threaded holes. The thermal grease coating module also includes a first positioning component, which passes through the mesh position adjustment hole and is threadedly connected to the frame threaded hole.

[0016] Therefore, by setting the mesh position adjustment hole extending along the first direction, the position of the coating mesh assembly relative to the frame positioning block in the length direction can be adjusted to suit coating mesh assemblies of different sizes, thereby improving the versatility of the stepped radiator thermal grease coating device of this utility model.

[0017] A preferred embodiment is that the positioning base includes a base plate, a width adjustment plate, a first support base, and a second support base; the width adjustment plate and the support block are both fixed to the base plate, the first support base and the second support base are both fixed to the width adjustment plate and arranged along a second direction, and the radiator positioning groove is formed on the top of the first support base and the second support base; the width adjustment plate is provided with a support base position adjustment hole extending along the second direction, and the bottom of the first support base and the second support base are provided with support base threaded holes. The radiator positioning module also includes a second positioning member, which passes through the support base position adjustment hole and is threadedly connected to the corresponding support base threaded hole.

[0018] Therefore, by opening support position adjustment holes extending along the second direction on the width adjustment plate, the relative position of the two support seats in the width direction can be adjusted, thereby enabling the application of thermal grease to radiators of different sizes, further improving the versatility of the stepped radiator thermal grease coating device.

[0019] In a preferred embodiment, the stepped radiator thermal grease coating device further includes a thermal grease scraper that is capable of sliding contact with the coating mesh assembly.

[0020] Therefore, manually applying the thermal grease evenly to the radiator surface using a thermal grease scraper ensures coating quality and improves work efficiency.

[0021] A preferred embodiment is that the guide wall is connected to a first coated mesh and a second coated mesh at its two ends in the first direction, respectively.

[0022] It can be seen that the guide wall is connected to the first coating mesh and the second coating mesh at its two ends in the first direction, which can ensure a smooth transition between the guide wall and each coating mesh and ensure the smooth movement of the thermal grease scraper.

[0023] A preferred embodiment is that there are two support blocks, which are respectively set on both sides of the positioning base in the second direction; at least one support block is provided with a limiting post, which protrudes outward from the side wall of the corresponding support block toward the other support block. When the coating mesh assembly is in the position of covering the heat sink positioning groove, the limiting post limits the thermal grease coating module below the thermal grease coating module.

[0024] Therefore, it can be seen that the limiting post can limit the position of the thermal grease coating module after it is covered.

[0025] To achieve the second objective mentioned above, this utility model provides a stepped radiator thermal grease coating device, comprising: a radiator positioning module, which includes a positioning base and a support block, wherein the positioning base is provided with a radiator positioning groove, and the support block is disposed on one side of the positioning base; a thermal grease coating module, which is hinged to the support block via a hinge shaft, and includes a coating mesh assembly capable of covering the radiator positioning groove above; the coating mesh assembly includes a first coating mesh sheet, a connector, and a second coating mesh sheet arranged sequentially along a first direction, wherein the first coating mesh sheet is higher than the second coating mesh sheet, and the connector is provided with a guide wall, which is inclined downwards from the end near the first coating mesh sheet to the end near the second coating mesh sheet in the first direction; an elastic reset member is provided at the end of the thermal grease coating module away from the radiator positioning groove, and the elastic restoring force of the elastic reset member forces the thermal grease coating module to rotate around the hinge shaft, so that the coating mesh assembly is away from the radiator positioning groove.

[0026] As can be seen from the above scheme, during use, the radiator can be directly placed into the radiator positioning slot, and then the thermal grease coating module is pressed down. A scraper is used to coat the grease from bottom to top in one go along the first direction, so that the thermal grease is evenly coated on the surface of the radiator, ensuring coating quality and improving work efficiency. After completion, the thermal grease coating module is released. By setting an elastic reset component at the end of the thermal grease coating module away from the radiator positioning slot, after releasing, the elastic restoring force of the elastic reset component forces the thermal grease coating module to rotate around the hinge axis and automatically tilt backward, leaving space for the operator to take out the workpiece. The operator can directly take out the radiator with thermal grease coating and put it into the electrical box for assembly with the outdoor unit motherboard.

[0027] This stepped radiator thermal grease coating device simplifies the existing complex and cumbersome operation method, eliminates the drawbacks of the current practice, improves work efficiency, and avoids the thermal grease from contaminating other parts of the product, which could lead to abnormal product quality. It also avoids the problem of uneven thermal grease thickness and the time difference between the two printing processes, which can cause the thermal grease to dry out and harden during the printing process. The stepped radiator thermal grease coating device provided by this utility model can also ensure the heat dissipation performance of the thermal grease, thereby ensuring product quality.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0036] First embodiment of the stepped radiator thermal grease coating device:

[0037] See Figure 1 and Figure 2 The stepped radiator thermal grease coating device includes a radiator positioning module 1, a thermal grease coating module 2, and a thermal grease scraper 3. The thermal grease scraper 3 can slide in contact with the thermal grease coating module 2 and the coating mesh assembly 21. By manually pushing and scraping the thermal grease scraper 3, the thermal grease is evenly coated on the surface of the radiator 4, ensuring coating quality and improving work efficiency.

[0038] The radiator positioning module 1 includes a positioning base 11 and two support blocks 12. The two support blocks 12 are respectively disposed on both sides of the positioning base 11 in the second direction. The positioning base 11 is provided with a radiator positioning groove 111 for placing the radiator 4. The support blocks 12 are disposed on one side of the positioning base 11. The thermal grease coating module 2 is hinged to the support blocks 12 through a hinge shaft 20. The center of gravity of the thermal grease coating module 2 is located on the side of the hinge shaft 20 away from the radiator positioning groove 111, ensuring that after the operator releases his hand, the thermal grease coating module 2 can rotate around the hinge shaft 20 and tilt backward. The coating mesh assembly 21 of the thermal grease coating module 2 opens the slot 110 of the radiator positioning groove 111.

[0039] See Figures 2 to 6 The thermal grease coating module 2 includes a coating mesh assembly 21, a first frame positioning block 22, a second frame positioning block 23, a connecting block 24, a first width limiter 25, and a second width limiter 26. The coating mesh assembly 21 can cover the heat sink positioning groove 111 on top.

[0040] The coating mesh assembly 21 includes a mesh mounting frame 211 and a first coating mesh 212, a connector 213, and a second coating mesh 214 arranged sequentially along a first direction. Both the first and second coating meshes 212 are horizontally arranged, with the first coating mesh 212 higher than the second coating mesh 214. The connector 213 is provided with a guide wall 210, which is inclined downwards along the first direction from one end near the first coating mesh 212 to the other end near the second coating mesh 214. Preferably, the two ends of the guide wall 210 in the first direction are respectively connected to the first coating mesh 212 and the second coating mesh 214 to ensure a smooth transition between the guide wall 210 and each coating mesh, ensuring smooth movement of the thermal grease scraper 3. In other embodiments, the end of the guide wall 210 near the first coating mesh 212 may be slightly lower than the first coating mesh 212, and / or the end of the guide wall 210 near the second coating mesh 214 may be slightly higher than the second coating mesh 214. In this embodiment, the first direction is the front-back direction, and the second direction is the left-right direction.

[0041] The mesh mounting frame 211 has a receiving groove 2110. The first coated mesh 212, the connector 213, and the second coated mesh 214 form the bottom wall of the receiving groove 2110. The receiving groove 2110 is used to hold thermal grease and prevent the thermal grease from being contaminated to other parts of the product. At the same time, the mesh mounting frame 211 is used to position each coated mesh and connector 213.

[0042] The first frame positioning block 22 and the second frame positioning block 23 are arranged along the second direction and both extend along the first direction. The coating mesh assembly 21 is fixed between the first frame positioning block 22 and the second frame positioning block 23 and is disposed near the first end of the thermal grease coating module 2. The connecting block 24 is disposed at the second end of the thermal grease coating module 2. In the first direction, the hinge shaft 20 is located between the coating mesh assembly 21 and the connecting block 24.

[0043] The hinge pin 20 passes sequentially through the first frame positioning block 22 and the second frame positioning block 23 along the second direction. A first width limiter 25 and a second width limiter 26 are both disposed on the hinge pin 20 and located between the first frame positioning block 22 and the second frame positioning block 23. The first width limiter 25 engages with the first frame positioning block 22 in the second direction, and the second width limiter 26 engages with the second frame positioning block 23 in the second direction. The width limiters limit and adjust the width between the first frame positioning block 22 and the second frame positioning block 23.

[0044] Both the first frame positioning block 22 and the second frame positioning block 23 are provided with mesh position adjustment holes 221, which extend along the first direction. The mesh mounting frame 211 is provided with a frame threaded hole 2111. The thermal grease coating module 2 also includes a first positioning member (not shown), which passes through the mesh position adjustment hole 221 and is threadedly connected to the frame threaded hole 2111. By providing mesh position adjustment holes 221 extending along the first direction, the position of the coating mesh assembly 21 relative to the frame positioning block in the length direction can be adjusted to suit coating mesh assemblies 21 of different sizes, thereby improving the versatility of the stepped radiator thermal grease coating device of this utility model.

[0045] The positioning base 11 includes a base plate 112, a width adjustment plate 113, a first support base 114, and a second support base 115. The width adjustment plate 113 and the support block 12 are both fixed to the base plate 112. The first support base 114 and the second support base 115 are both fixed to the width adjustment plate 113 and arranged along a second direction. A radiator positioning groove 111 is formed on the top of the first support base 114 and the second support base 115. The width adjustment plate 113 has a support base position adjustment hole 1131 extending along the second direction. The bottom of the first support base 114 and the second support base 115 both have support base threaded holes (not shown). The radiator positioning module 1 also includes a second positioning member (not shown), which passes through the support base position adjustment hole 1131 and is threadedly connected to the corresponding support base threaded hole. By opening a support position adjustment hole 1131 extending along the second direction on the width adjustment plate 113, the relative position of the two support seats in the width direction can be adjusted, thereby enabling the application of thermal grease to radiators 4 of different sizes, further improving the versatility of the stepped radiator thermal grease coating device.

[0046] At least one support block 12 is provided with a limiting post 13. In this embodiment, both support blocks 12 are provided with limiting posts 13. The limiting post 13 protrudes outward from the side wall of the corresponding support block 12 toward the other support block 12. When the coating mesh assembly 21 is in the position of covering the heat sink positioning groove 111, the limiting post 13 limits the thermal grease coating module 2 below it.

[0047] In use, the radiator 4 can be placed directly into the radiator positioning slot 111, and then the thermal grease coating module 2 can be pressed down. The thermal grease scraper 3 can be used to coat the grease from bottom to top in one go along the first direction. After completion, the thermal grease coating module 2 can be released. By setting the center of gravity of the thermal grease coating module 2 on the side away from the radiator positioning slot 111, the thermal grease coating module 2 becomes a non-powered device. When released, it will automatically tilt backward, and the coating mesh assembly 21 will move away from the radiator 4, leaving space for the operator to take out the workpiece. The operator can directly take out the radiator 4 that has been coated with thermal grease and put it into the electrical box for assembly with the outdoor unit motherboard.

[0048] As can be seen from the above, this stepped radiator thermal grease coating device simplifies the existing complex and cumbersome operation method, eliminates the drawbacks of the current practice, improves work efficiency, and avoids the thermal grease from being contaminated to other parts of the product, which would lead to abnormal product quality. It also avoids the problem of uneven thermal grease thickness and the time difference in the existing two printing processes, which can easily cause the thermal grease to dry out and harden during the printing process. The stepped radiator thermal grease coating device provided by this utility model can also ensure the heat dissipation performance of the thermal grease, thereby ensuring product quality.

[0049] Second embodiment of the stepped radiator thermal grease coating device:

[0050] As a description of the second embodiment of the stepped radiator thermal grease coating device of this utility model, the following description only focuses on the differences from the first embodiment of the stepped radiator thermal grease coating device described above.

[0051] In this embodiment, the position of the center of gravity of the thermal grease coating module is not limited. It can be located on the side of the hinge away from the heat sink positioning groove or on the side of the hinge close to the heat sink positioning groove.

[0052] In this embodiment, an elastic reset member is provided at the end of the thermal grease coating module away from the radiator positioning slot. The elastic restoring force of the elastic reset member forces the thermal grease coating module to rotate around the hinge axis, so that the coating mesh assembly is away from the radiator positioning slot. Thus, after the operator releases their grip, the elastic restoring force of the elastic reset member forces the thermal grease coating module to rotate around the hinge axis and automatically tilt backward, providing space for the operator to remove the workpiece. Preferably, the elastic reset member is a tension spring.

[0053] Finally, it should be emphasized that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications.
