Description

Technical Field

[0001] The utility model relates to the technical field of ceramic sheet gluing, in particular to a tooling fixture for gluing ceramic sheets. Background Art

[0002] A ceramic sheet is a sheet material made of specific materials, mainly made of materials such as alumina, aluminum nitride or silicon carbide. Among them, alumina and aluminum nitride are relatively common materials, while the price of silicon carbide material is usually high. Therefore, the ceramic sheet is the basic material for some electronic circuit structure technologies and can be used to make high-power semiconductor modules, electronic heaters, and electronic components used in automotive electronics and aerospace.

[0003] Among them, the ceramic sheets used in electronic components need to be coated with glue before use to dissipate heat and conduct heat for certain devices in electronic products, such as computer processors. Currently, the glue injection molds for ceramic sheets on the market are basically divided into two categories. One category is large in volume, automated, suitable for production on an assembly line, and costly; the other category has a smaller mold volume and is suitable for the self-research and development stage. Among them, the glue injection mold in the research and development stage glues the ceramic sheet on one side in sequence. However, ceramic sheets generally need to be glued on both sides, and this type of mold does not have a specific design for double-sided gluing. Summary of the Utility Model

[0031] Embodiment 1

[0032] Refer to Figure 1 - Figure 8 , which is the first embodiment of the present utility model, provides a tooling fixture for gluing ceramic chips. This device includes a bearing unit 100, including a bearing plate 101; a fixing unit 200, including a fixing plate 201 arranged on the bearing plate 101, a limiting plate 202 arranged on the fixing plate 201, and a moving unit 300, including a moving plate 301 arranged on the bearing plate 101, a connecting plate 303 arranged below the moving plate 301, and a limiting unit 400, including a fixture plate one 401 arranged on one side of the fixing plate 201, a hinge device 405 arranged on the fixture plate one 401, a fixture plate two 404 arranged on one side of the hinge device 405, and a limiting block 406 arranged on the fixture plate one 401. The ceramic chip is fixed by the fixture plate one 401 and the fixture plate two 404, and then the limiting unit 400 is fixed by the fixing plate 201 and the moving plate 301, so as to facilitate the staff to perform gluing treatment on both sides of the ceramic chip at the same time, improving the work efficiency and use comfort of the staff.

[0033] Wherein, a guide rail 205 is arranged inside the fixing plate 201, a guide rail assembly 308 is arranged inside the moving plate 301, a guide rail main body 404c corresponding to the guide rail 205 and the guide rail assembly 308 is arranged on one side of the fixture main body 404a, and guide surfaces 204 are arranged on one side of both the fixing plate 201 and the moving plate 301. The guide rail main body 404c is guided by the guide rail 205 and the guide rail assembly 308. At the same time, the rollers inside the guide rail 205 and the guide rail assembly 308 reduce the friction between the guide rail 205 and the guide rail assembly 308 and the guide rail main body 404c, facilitating the staff to insert the fixture plate one 401 and the fixture plate two 404 between the fixing plate 201 and the moving plate 301 for gluing treatment, and facilitating the staff to take it out after the gluing is completed, thereby increasing the use comfort of the staff.

[0034] During use, the staff first determines the size of the ceramic chips to be produced, and then installs the ceramic chips between the first fixture plate 401 and the second fixture plate 404. The structures of the first fixture plate 401 and the second fixture plate 404 are exactly the same. At this time, the two are closed, so that the first fixture plate 401 and the second fixture plate 404 fix the ceramic chip between them. Then, the staff inserts the closed first fixture plate 401 and second fixture plate 404 along the guiding surface 204 on one side of the fixed plate 201 and the moving plate 301. At this time, the guide rail body 404c on the outside of the first fixture plate 401 and the second fixture plate 404 will be inserted into the guide rail 205 and the guide rail assembly 308. Furthermore, the guide rail 205 and the guide rail assembly 308 guide the guide rail body 404c, enabling the first fixture plate 401 and the second fixture plate 404 to quickly slide to one end. At the same time, the rollers inside the guide rail 205 and the guide rail assembly 308 reduce the friction between them and the guide rail body 404c, facilitating the staff to insert the first fixture plate 401 and the second fixture plate 404 between the fixed plate 201 and the moving plate 301 for glue coating treatment, and also facilitating the staff to take them out after the glue coating is completed, thereby increasing the comfort of use for the staff.

[0035] Embodiment 2

[0036] Refer to Figure 1 - Figure 8 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a movable groove 103 is provided on the bearing plate 101, and a fixing bolt 304 corresponding to the movable groove 103 is provided at the bottom of the connecting plate 303. A fixing nut 305 is provided on the outside of the fixing bolt 304. By moving the fixing bolt 304 in the movable groove 103, the distance between the fixed plate 201 and the moving plate 301 is adjusted, facilitating the fixation of the first fixture plate 401 and the second fixture plate 404 with different thicknesses, and then fixing it with the fixing nut 305, thereby increasing the practicality and application range of the device.

[0037] Compared with Embodiment 1, further, a connecting card slot 302 corresponding to the limiting plate 202 is provided on the moving plate 301. By using the connecting card slot 302 in cooperation with the limiting plate 202, the minimum distance between the fixed plate 201 and the moving plate 301 is limited, and at the same time, the first fixture plate 401 and the second fixture plate 404 entering between them are limited, preventing them from moving and deviating, which is not convenient for the staff to insert the insertion post 307 into the moving plate 301 and the fixed plate 201 to fix them.

[0038] During use, for different electronic products, the sizes and thicknesses of the heat-conducting and heat-dissipating ceramic sheets used are also different, which results in different sizes and thicknesses of the fixture plate one 401 and the fixture plate two 404. At this time, the staff first rotates and adjusts the fixing bolt 304 outside the fixing nut 305 according to the sizes and thicknesses of the fixture plate one 401 and the fixture plate two 404, and then adjusts the moving plate 301 to make the distance between the moving plate 301 and the fixing plate 201 adapt to the sizes and thicknesses of the fixture plate one 401 and the fixture plate two 404. Then, the fixture plate one 401 and the fixture plate two 404 are inserted between the moving plate 301 and the fixing plate 201 along the guiding surface 204, and the handles 403 at the tops of the fixture plate one 401 and the fixture plate two 404 are held tightly. Furthermore, the fixture plate one 401 and the fixture plate two 404 held tightly are used to fix and limit the space between the moving plate 301 and the fixing plate 201. At this time, the staff rotates and adjusts the fixing nut 305 again, so as to fix the moving plate 301 on the top of the bearing plate 101, thereby adjusting and fixing the distance between the moving plate 301 and the fixing plate 201, which is convenient for the staff to re-insert the fixture plate one 401 and the fixture plate two 404 next time to apply glue to the ceramic sheets inside them, thus increasing the comfort of use for the staff. At the same time, the moving plate 301 and the fixing plate 201 can fix the fixture plate one 401 and the fixture plate two 404 with different thicknesses, increasing the practicability and application range of the device.

[0039] The rest of the structure is the same as that of Embodiment 1.

[0040] Embodiment 3

[0041] Refer to Figure 1 - Figure 8 This is the third embodiment of the present utility model. The difference between this embodiment and the second embodiment is that: connection insertion plates 402 are provided on one side of both the fixture plate one 401 and the fixture plate two 404, an insertion post 307 corresponding to the connection insertion plate 402 is provided on one side of the moving plate 301, a jack handle 306 is provided at one end of the insertion post 307, a collection bin 104 is provided inside the moving plate 301, a connection port 105 corresponding to the receiving slot 404b is provided at one end of the collection bin 104, a connection hole 102 is provided on the outside of the bearing plate 101, and a handle 403 is provided on the top of the fixture plate one 401. Through the handle 403, it is convenient for the staff to close the fixture plate one 401 and the fixture plate two 404 together, and then insert them between the fixing plate 201 and the moving plate 301 for gluing. At the same time, it is convenient for the staff to take them out, thereby increasing the comfort of use and work efficiency of the staff.

[0042] Compared with Embodiment 2, further, arc surfaces are equidistantly arranged on the inner side of the limiting block 406. The arc surfaces increase the friction between the periphery of the ceramic sheet and the limiting block 406, so that the ceramic sheet can be stably fixed therebetween. When the first clamping plate 401 and the second clamping plate 404 are inserted between the moving plate 301 and the fixed plate 201, at this time, the staff holds the jack handle 306 and sequentially passes the plug post 307 at one end thereof through the moving plate 301, 4020, and the fixed plate 201, thereby fixing the three of them. The plug post 307 with a frustum shape at one end facilitates the staff to start inserting and fixing it, thereby improving the work efficiency of the staff.

[0043] During the use process, after the staff inserts the first clamping plate 401 and the second clamping plate 404 between the moving plate 301 and the fixed plate 201, then holds the jack handle 306 and sequentially passes the plug post 307 at one end thereof through the moving plate 301, 4020, and the fixed plate 201, thereby fixing the three of them. Then, the collection bin 104 is inserted into the inner sides of the fixed plate 201 and the moving plate 301, and the connection port 105 at one end of the collection bin 104 is inserted into the receiving card slot 404b. At this time, the staff applies double-sided glue to the ceramic sheet fixed inside the first clamping plate 401 and the second clamping plate 404. The ceramic sheet is firmly fixed therebetween, which is convenient for the staff to evenly apply glue to the ceramic sheet, thereby improving the heat conduction efficiency and heat dissipation efficiency of the ceramic sheet. At the same time, during the glue application process by the staff, there will be excess glue remaining on the surfaces of the first clamping plate 401 and the second clamping plate 404. At this time, the staff can directly and quickly clean the excess glue downward into the collection bin 104, thereby preventing the excess glue from dripping onto other devices, causing pollution and waste, and further reducing the glue application cost of the ceramic sheet and the use comfort of the staff. After the glue application is completed, the staff first holds the jack handle 306 and removes the plug post 307, then holds the handle 403 and slides it out along the fixed plate 201. After it is taken out, the second clamping plate 404 is rotated along one side of the hinge device 405. At this time, the glued ceramic sheet will be stuck inside the limiting block 406. Then, the staff sequentially takes out and installs the glued ceramic sheets.

[0044] The remaining structures are the same as those of Embodiment 2.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
