Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0045] The present application provides a thermal paste quick-brushing device for realizing the scraping and coating of thermal paste for a power supply.

[0046] The following will describe in detail specific embodiments of the thermal paste quick-brushing device of the present application in conjunction with the accompanying drawings.

[0047] Figure 1 It is a schematic structural diagram of the thermal paste quick-brushing device in this embodiment. Figure 2 It is Figure 1 a schematic diagram in the A-A direction in Figure 3 and is a schematic exploded structural diagram of the thermal paste quick-brushing device in this embodiment.

[0048] Referring to Figures 1 to 3 , the thermal paste quick-brushing device includes a base 1, a cover plate 2 and a limiting component 3. An opening is provided on one side of the base 1 along its own height direction. The cover plate 2 is detachably connected to the opening of the base 1 to open and close the opening of the base 1. The surface of the cover plate 2 is used to hold the thermal paste. A through hole 21 is provided on the cover plate 2. The limiting component 3 is fixedly connected inside the base 1. One side of the limiting component 3 along the height direction has an opening, thus forming a limiting groove 31. The opening direction of the limiting groove 31 is the same as the opening direction of the base 1. The limiting groove 31 is used to accommodate and limit the power supply. Wherein, the cover plate 2 is located on the opening side of the limiting component 3 and is used to abut against the power supply. The through hole 21 communicates with the limiting groove 31. The through hole 21 is correspondingly located outside the heat conduction area of the power supply. The shape of the through hole 21 matches the heat conduction area of the power supply and is used for the thermal paste to pass through and adhere to the heat conduction area of the power supply.

[0049] In the above thermal paste quick-brushing device, the position of the power supply is restricted and fixed by the limiting groove 31 of the limiting component 3. In this way, the position of the heat conduction area of the power supply can be fixed, so that when the cover plate 2 is connected to the base 1, the through hole 21 on the cover plate 2 will correspond to the heat conduction area of the power supply. Since the shape and size of the through hole 21 match those of the heat conduction area of the power supply, the heat conduction area of the power supply can be completely exposed. When applying thermal paste to the heat conduction area of the power supply subsequently, the through hole 21 can be used to limit the application shape, range, thickness, etc. of the thermal paste, so as to ensure that the thermal paste can be regularly and evenly adhered to the heat conduction area of the power supply, and further ensure that the thermal paste can perform its functions normally.

[0050] In addition, when using the above thermal paste quick-brushing device to apply thermal paste to the power supply, the operation difficulty is reduced, the work efficiency can be improved to a certain extent, and other components on the power supply can be avoided from being damaged, ensuring the yield of the entire power supply.

[0051] Referring to Figure 1 and Figure 3 , an opening is provided on one side of the base 1 along its own height direction. In actual application, the base 1 is arranged with its opening facing upward.

[0052] For the convenience of description, taking the state of the thermal paste quick-brushing device during actual application as an example, it is stipulated that the direction towards the opening of the base 1 is upward, and vice versa is downward.

[0053] The base 1 includes a substrate 11 and support plates 12 respectively arranged at opposite ends of the substrate 11.

[0054] The substrate 11 is rectangular. In other embodiments, the substrate 11 may also be trapezoidal or other shapes.

[0055] In this embodiment, the two support plates 12 are respectively arranged at both ends of the substrate 11 in the length direction. The two substrates 11 are arranged in parallel at intervals. At this time, the rectangular design of the substrate 11 facilitates the arrangement of the two support plates 12, that is, only by aligning the support plates 12 with the ends of the substrate 11 can the two support plates 12 be arranged in parallel at intervals.

[0056] The support plate 12 protrudes upward from the substrate 11. Among them, the two support plates 12 and the substrate 11 enclose a receiving groove with an upward opening for receiving a power supply.

[0057] Support positions are formed on the support plate 12, and the support positions on the two support plates 12 are symmetrically arranged to ensure that the two symmetric support positions on the two support plates 12 can be located on the same plane and cooperate to form a support surface.

[0058] Reference Figures 1 to 3 , the support plate 12 includes two support portions 121 arranged at intervals. The two support portions 121 are located on the same plane and are mirror-symmetrically arranged. Specifically, the two support portions 121 are distributed at intervals along the width direction of the substrate 11.

[0059] The support portion 121 includes a plurality of support bodies 1211 distributed along the width direction of the substrate 11. The heights of the plurality of support bodies 1211 of each support portion 121 increase from the inside to the outside in the width direction of the substrate 11, so that adjacent two support bodies 1211 form a stepped structure. Among them, the inside here refers to the direction towards the interval between the two support portions 121, and vice versa is the outside. The inside and outside directions in the following description of the structure of the support plate 12 refer to here.

[0060] In this embodiment, the two symmetrically arranged support bodies 1211 in the two support portions 121 cooperate to form a support position, and the two symmetric support positions on the two support plates 12 cooperate to form a support surface. Specifically, the support position is composed of the top surfaces of the two symmetrically arranged support bodies 1211 in the two support portions 121, and the support surface is composed of the top surfaces of the four support bodies 1211 with the same height.

[0061] Since each supporting portion 121 includes a plurality of supporting bodies 1211, and the two supporting portions 121 of each support plate 12 are arranged in mirror symmetry, the heights of the plurality of supporting bodies 1211 of each supporting portion 121 increase from the inside to the outside in the width direction of the substrate 11. In this way, the two supporting portions 121 can cooperate with each other to form a plurality of supporting positions, and the two support plates 12 cooperate with each other to jointly form a plurality of supporting surfaces, and there is a height difference between adjacent two supporting surfaces.

[0062] Figure 4 This is a top view of the thermal paste quick-brushing device in this embodiment.

[0063] Reference Figures 1 to 4 , the cover plate 2 is detachably connected to the opening of the base 1 to open and close the opening of the base 1, so as to realize the opening and closing of the accommodating groove of the base 1. In this way, it is convenient to detach the cover plate 2 from the base 1, which is convenient for putting the power supply into the accommodating groove of the base 1 from the opening of the base 1 or taking out the power supply from the base 1. Similarly, it is also convenient to connect the cover plate 2 to the base 1 to close the opening of the base 1.

[0064] In this embodiment, the cover plate 2 is located on the supporting surface, and the two ends of the cover plate 2 in the length direction are respectively connected and fixed to a support plate 12. Moreover, when the cover plate 2 is connected to the base 1, it can be in contact with the power supply.

[0065] The number of the cover plates 2 is multiple, and the areas of the cover plates 2 are all different. Each cover plate 2 is correspondingly arranged on the supporting surface formed by the cooperation of four supporting bodies 1211 with the same height. That is to say, when the cover plates 2 are connected to the base 1, they are respectively located at different height positions of the support plate 12. In this way, the spaces formed by the cover plates 2 and the substrate 11 when the cover plates 2 are connected to the base 1 will have different heights. Since the cover plate 2 will be in contact with the power supply during actual use, it can be seen that different cover plates 2 can be selected to be connected to the base 1 during actual use, so as to adapt to power supplies with different heights. Thus, the thermal paste quick-brushing device can be compatible with power supplies of various heights, improving the versatility of the thermal paste quick-brushing device.

[0066] In this embodiment, the fact that the areas of the cover plates 2 are different is mainly reflected in: while keeping the length dimensions of the cover plates 2 the same, the width dimensions of the cover plates 2 are changed. Among them, the width dimensions of the cover plates 2 are mainly determined according to the width dimensions of the corresponding supporting surfaces. Since the supporting surface is composed of the top surfaces of four supporting bodies 1211 with the same height, the width dimensions of the cover plates 2 are greater than the distance between the inner sides of the two supporting bodies 1211 with the same height of the same support plate 12 and do not exceed the distance between the outer sides of the two supporting bodies 1211 with the same height of the same support plate 12, so as to facilitate the cover plate 2 to be arranged on the supporting surface formed by the cooperation of four supporting bodies 1211 with the same height.

[0067] In this embodiment, the cover plate 2 is magnetically fixed to the support plate 12. Exemplarily, a magnetic unit is provided at the end of each support body 1211 away from the substrate 11 along its height direction, and a magnetic attraction portion corresponding to the magnetic unit is provided on the cover plate 2. The magnetic unit is magnetically connected to the magnetic attraction portion to realize the connection and fixation of the cover plate 2 and the support plate 12. In this embodiment, the connection between the cover plate 2 and the support plate 12 is realized by magnetic attraction fixation. During actual operation, the cover plate 2 can be directly removed from the support plate 12, or the cover plate 2 can be directly placed on the support position of the support plate 12, so as to realize the connection and fixation of the cover plate 2 and the support plate 12, and the taking is convenient and fast.

[0068] The cover plate 2 and the support plate 12 can also be snap-connected. Two stepped structures symmetrically arranged on each support plate 12 form a clamping position for clamping the end of the cover plate 2. Specifically, the width dimension of the cover plate 2 is the distance between the outer sides of two support bodies 1211 with the same height on the same support plate 12. Taking the example that two adjacent support bodies 1211 forming a stepped structure are respectively the first support body and the second support body, and the cover plate 2 is correspondingly placed on the support surface formed by four first support bodies with the same height. Among them, the second support body is located outside the first support body, and the height of the second support body is greater than that of the first support body. In this way, when the cover plate 2 is placed on the first support surface formed by four first support bodies with the same height, the end of the cover plate 2 in the width direction can abut against the inner side of the second support body. That is to say, the clamping position is surrounded by the top surfaces of two first support bodies with the same height and the inner side surfaces of two second support bodies with the same height on each support plate. The cooperation of four first support bodies with the same height and four second support bodies with the same height can realize the snap connection of the cover plate 2.

[0069] In this embodiment, the cover plate 2 is magnetically fixed to the support plate 12, and at the same time, the cover plate 2 is snap-connected to the support plate 12, so as to enhance the connection stability between the cover plate 2 and the support plate 12. In other embodiments, the cover plate 2 can also be only magnetically fixed to the support plate 12, or the cover plate 2 is only snap-connected to the support plate 12.

[0070] In this embodiment, a through hole 21 is provided on the cover plate 2. Among them, during actual application, after the cover plate 2 is connected to the base 1, the through hole 21 will be correspondingly located above the heat conduction area of the power supply, exposing the heat conduction area of the power supply. And because the cover plate 2 can abut against the power supply, it is convenient for subsequent heat conduction paste application operation on the heat conduction area, so that the heat conduction paste can pass through the through hole 21 to adhere to the heat conduction area of the power supply.

[0071] In this embodiment, the shape of the through hole 21 matches the heat conduction area of the power supply, and the thickness of the cover plate 2 is the same as the thickness of the thermal paste required by the power supply. This design enables the use of the through hole 21 to limit the application shape, range, thickness, etc. of the thermal paste, so as to ensure that the thermal paste can be attached to the heat conduction area of the power supply regularly and evenly, thereby ensuring that the thermal paste can perform its functions normally.

[0072] In this embodiment, the number of the through holes 21 can be multiple, and each through hole 21 is arranged corresponding to the heat conduction area of a power supply, so that the application of the thermal paste to the heat conduction areas of multiple power supplies can be realized at one time, improving the work efficiency.

[0073] In other embodiments, the number of the through holes 21 can also be one, and the specific setting is determined according to needs.

[0074] In this embodiment, the cover plate 2 includes a plate body 22 and a mesh plate. Among them, the through hole 21 is arranged on the plate body 22.

[0075] One side of the plate body 22 is open to form a groove 23 for containing the thermal paste. The groove 23 is communicated with the through hole 21. When the cover plate 2 is connected to the base 1, the opening of the groove 23 of the plate body 22 faces upward, and the top surface of the plate body 22 at the groove extends in the horizontal direction.

[0076] The mesh plate is arranged at the through hole 21 and fixedly connected to the plate body 22. A plurality of through holes 34 arranged in an array are provided on the mesh plate. The through holes 34 are communicated with the through hole 21, and the thermal paste passes through the through holes 34 on the mesh plate for attachment to the heat conduction area. In actual application, during the process of applying the thermal paste to the heat conduction area of the power supply, the mesh plate can ensure that the thermal paste is evenly applied to the heat conduction area of the power supply, preventing the thermal paste from leaking out and touching other components.

[0077] Reference Figure 3 , the limiting component 3 is fixedly connected inside the base 1. One side of the limiting component 3 in the height direction has an opening to form a limiting groove 31. The opening direction of the limiting groove 31 is the same as the opening direction of the base 1. The limiting groove 31 is used to accommodate and limit the power supply, thereby fixing the position of the power supply. At this time, when the cover plate 2 is connected to the base 1, the through hole 21 on the cover plate 2 is communicated with the limiting groove 31.

[0078] In this embodiment, the limiting component 3 includes a connecting plate 32 and a limiting member 33.

[0079] The connecting plate 32 is located inside the base 1 and is detachably connected to the base 1, so as to facilitate the removal of the connecting plate 32 from the base 1 for operations such as replacing and repairing the limiting component 3, and at the same time, it is also convenient to connect the connecting plate 32 to the base 1.

[0080] In this embodiment, the connecting plate 32 is screwed to the substrate 11. Specifically, a plurality of connecting holes 321 are provided on the connecting plate 32, and a plurality of fixing holes 111 corresponding to the connecting holes 321 are provided on the substrate 11. A connecting member is inserted through each connecting hole 321 and the corresponding fixing hole 111, and the connecting member is threadedly connected to the connecting plate 32 and the substrate 11, thereby realizing the connection and fixation of the connecting plate 32 and the substrate 11.

[0081] The connecting hole 321 and / or the fixing hole 111 is a waist-shaped hole, so that the connecting member can move within the connecting hole 321 and / or the fixing hole 111, thereby adjusting the position of the connecting plate 32 relative to the substrate 11.

[0082] Figure 5 For Figure 4 Schematic diagram in the B-B direction in

[0083] Reference Figure 3 And Figure 5 As shown in [[REF]] and [[REF]], a limiting member 33 is provided on the surface of the connecting plate 32, and the limiting member 33 and the connecting plate 32 enclose a limiting groove 31. At this time, the design that the connecting plate 32 can move relative to the substrate 11 facilitates adjusting the position of the limiting groove 31, so as to ensure that the limiting groove 31 can be correspondingly distributed with the through holes 21 on the cover plate 2.

[0084] In this embodiment, the number of the limiting members 33 can be multiple, and the multiple limiting members 33 are arranged at intervals along the length direction of the connecting plate 32. Each limiting member 33 and the connecting plate 32 enclose a limiting groove 31, and each limiting groove 31 is used to accommodate and limit one power supply, and there is at least one through hole 21 corresponding to the upper part of each limiting groove 31. The above design enables the limiting assembly 3 to limit and accommodate multiple power supplies at one time, and further enables the thermal paste quick-brushing device to apply thermal paste to multiple power supplies at one time, improving work efficiency.

[0085] In other embodiments, the multiple limiting members 33 can also be arranged in an array on the connecting plate 32, and the specific setting is determined according to needs.

[0086] In this embodiment, the limiting member 33 includes a plurality of spaced-apart limiting portions 331, and the plurality of limiting portions are arranged in a ring shape. The plurality of limiting portions 331 and the connecting plate 32 enclose a limiting groove 31, and each limiting portion 331 is used to fit and abut against the outer periphery of the power supply. The plurality of limiting portions 331 cooperate together to abut against the outer periphery of the power supply to realize the limiting function of the power supply.

[0087] Exemplarily, in this embodiment, the number of the limiting portions 331 is four, each limiting portion 331 is in an L shape, and the four limiting portions are arranged at intervals in a rectangle. Each limiting portion correspondingly abuts against a corner of the rectangular power supply, so that the power supply can be stably limited, and the structure is simple.

[0088] In other embodiments, the number of the limiting parts 331 can also be in any other shape such as a U shape, as long as the shape of the limiting part 331 is adapted to the outer periphery of the power supply, so as to ensure that the limiting part 331 can fit and abut against the power supply, thereby improving the limiting effect of the limiting member 33 formed by combining a plurality of limiting parts 331 on the power supply.

[0089] In this embodiment, a plurality of adjustment holes are provided on the connecting plate 32, and the adjustment holes are arranged in one-to-one correspondence with the limiting parts 331. A through hole is provided on the limiting part 331, and a fastener is inserted into each adjustment hole and the corresponding through hole for connecting and fixing the connecting plate 32 and the limiting part 331.

[0090] In this embodiment, each limiting part 331 is movably connected to the connecting plate 32, and the plurality of limiting parts 331 can approach or move away from each other to adjust the inner diameter of the limiting groove 31, so as to be compatible with power supplies having different length and width dimensions, thereby improving the versatility of the thermal paste quick-brushing device. In addition, when there are a plurality of limiting members 33, each limiting member 33 can accommodate and limit power supplies having the same length and width dimensions, or can accommodate and limit power supplies having different length and width dimensions. That is to say, the thermal paste quick-brushing device can simultaneously perform the thermal paste application work on a plurality of power supplies having the same length and width dimensions or a plurality of power supplies having different length and width dimensions, thereby improving the compatibility of the thermal paste quick-brushing device.

[0091] Specifically, the adjustment hole and / or the through hole is an oblong hole, and the fastener can move in the adjustment hole and / or the through hole to adjust the position of the limiting part 331, so as to expand or reduce the inner diameter of the limiting groove 31.

[0092] In other embodiments, a through hole is provided on the limiting part 331, and the through hole is a circular hole. A plurality of circular holes are provided on the connecting plate 32 corresponding to each limiting part 331. That is to say, by inserting the fastener into the through hole and any one of the circular holes, the position of the limiting part 331 relative to the connecting plate 32 can be changed.

[0093] In this embodiment, a through hole 34 is further provided on the limiting component 3, and the through hole 34 communicates with the limiting groove 31. Wherein, at least one through hole 34 is provided at each limiting position. Specifically, the through hole 34 is provided on the connecting plate 32 for an operator's hand or other tools to extend into to contact the power supply located in the limiting groove 31, so as to facilitate pushing out the power supply from the opening side of the limiting groove 31, so as to facilitate removing the power supply from the limiting component 3.

[0094] In this embodiment, the thermal paste quick-brushing device further includes a paste scraping member. The paste scraping member is used to scrape off the thermal paste located on the cover plate 2, so that the thermal paste passes through the through hole 21 and adheres to the power supply. During the process of scraping the thermal paste by the paste scraping member, due to the flat structure of the cover plate 2 itself and the cooperation of the paste scraping member with the through hole 21 of the cover plate 2 for applying the thermal paste, the uniformity and flatness of the thermal paste application can be improved.

[0095] Reference Figures 1 to 5 ,The thermal paste quick-brushing device further includes a magnetic member 4, which is arranged on the base 1 and is used for magnetically absorbing and storing the paste-scraping member. In this embodiment, the storage of the paste-scraping member is realized by magnetic absorption. After the paste-scraping member is used up, it can be directly placed on the magnetic member 4, so as to realize the storage of the paste-scraping member, avoid the loss of the paste-scraping member, and facilitate the next use.

[0096] Specifically, the magnetic member 4 is arranged on the outside of one of the support plates 12. By centrally arranging the magnetic member 4 and the support plate 12, the layout of the entire thermal paste quick-brushing device is optimized, and it can be avoided that the magnetic member 4 interferes with other structures.

[0097] The working principle of the above thermal paste quick-brushing device is as follows:

[0098] S1. Arrange the base 1 with the opening facing upward.

[0099] S2. Connect and fix the connecting plate 32 of the limiting component 3 to the substrate 11.

[0100] S3. According to the length and width dimensions of the power supply, connect the multiple limiting parts 331 of each limiting member 33 to the connecting plate 32, and / or adjust the positions of the multiple limiting parts 331 of each limiting member 33 relative to the connecting plate 32 to adjust the inner diameter of the limiting groove 31 formed by enclosing the multiple limiting parts 331 and the connecting plate 32. Then, place a power supply in each limiting groove 31, or place a power supply in some of the limiting grooves 31.

[0101] S4. According to the height dimension of the power supply, select a suitable cover plate 2 and place it on the supporting surface corresponding to the height, and the cover plate 2 is magnetically fixed to the corresponding support body 1211.

[0102] S5. According to the relative position between the through hole 21 and the heat conduction area of the power supply, adjust the position of the connecting plate 32 relative to the substrate 11 so that the heat conduction area of the power supply fixed in the limiting groove 31 is correspondingly located below the through hole 21, and the through hole 21 can completely expose the range of the heat conduction area.

[0103] S6. Pour an appropriate amount of thermal paste into the groove 23 on the top of the cover plate 2, scrape the thermal paste by moving the paste-scraping member along the cover plate 2, and scrape the thermal paste to adhere to the heat conduction area of the power supply through the through hole 21 until the upper surface of the thermal paste adhered to the heat conduction area is flush with the surface of the cover plate 2, so as to complete the uniform and standard application of the thermal paste on the power supply.

[0104] S7. Remove the cover plate 2 and take out the power supply on which the thermal paste has been applied.

[0105] When applying thermal paste to power supplies in the same batch, that is, when applying thermal paste to a large number of power supplies with the same length, width, and height dimensions, first complete the above steps S1 to S7, and if it is necessary to continue the thermal paste application work for the power supplies in this batch, subsequently, the power supply can be directly placed in the limit slot 31 and the cover plate 2 can be covered, and then steps S6 and S7 can be repeated until the thermal paste application work for the power supplies in this batch is completed.

[0106] When applying thermal paste to at least two batches of power supplies with the same height but different length and width dimensions, first complete the thermal paste application for the power supplies in the first batch according to the above operations. When applying thermal paste to the power supplies in the second batch, first repeat steps S3 and S5 to adjust and fix the corresponding positions of the subsequent power supply's heat conduction area and the through hole 21. After covering the cover plate 2, steps S6 and S7 can be repeated. Subsequently, when applying thermal paste to other power supplies in the second batch, the power supply can be directly placed in the limit slot 31 and the cover plate 2 can be covered, and then steps S6 and S7 can be repeated until the thermal paste application work for the power supplies in the second batch is completed. And so on until the thermal paste application work for all batches of power supplies is completed.

[0107] When applying thermal paste to at least two batches of power supplies with different heights but the same length and width dimensions, first complete the thermal paste application for the power supplies in the first batch according to the above operations. When performing the thermal paste application work for the power supplies in the second batch, first repeat the above step S4, and then the power supply can be directly placed in the limit slot 31 and the cover plate 2 can be covered, and then steps S6 and S7 can be repeated until the thermal paste application work for the power supplies in the second batch is completed. And so on until the thermal paste application work for all batches of power supplies is completed.

[0108] When applying thermal paste to at least two batches of power supplies with different heights and different length and width dimensions, first complete the thermal paste application for the power supplies in the first batch according to the above operations. When performing the thermal paste application work for the power supplies in the second batch, repeat the above steps S3 to S7 until the thermal paste application work for the power supplies in the second batch is completed. And so on until the thermal paste application work for all batches of power supplies is completed.

[0109] From the above technical solutions, it can be seen that the present utility model has at least the following advantages and positive effects:

[0110] In the above thermal paste quick-brushing device, the position of the power supply is restricted and fixed through the limiting groove of the limiting component. In this way, the position of the heat-conducting area of the power supply can be fixed, so that when the cover plate is connected to the base, the through hole on the cover plate will correspond to the heat-conducting area of the power supply. Since the through hole matches the shape and size of the heat-conducting area of the power supply, the heat-conducting area of the power supply can be completely exposed. When applying thermal paste to the heat-conducting area of the power supply subsequently, the through hole can be used to limit the application shape, range, thickness, etc. of the thermal paste, so as to ensure that the thermal paste can be attached to the heat-conducting area of the power supply regularly and evenly, and further ensure that the thermal paste can perform its functions normally.

[0111] In addition, using the above thermal paste quick-brushing device to apply thermal paste to the power supply reduces the operation difficulty, can improve the work efficiency to a certain extent, and can also avoid damaging other components on the power supply, ensuring the yield of the entire power supply.

[0112] Although the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
