[0038] To describe in detail the technical content, achieved purpose and effects of the present utility model, the following is described in conjunction with the implementation manners and with reference to the accompanying drawings.

[0039] An embodiment of the present utility model provides a non - stick fixture for a chip bonding platform, including an adjusting piece, a non - stick platform and a base;

[0040] A window is provided on the adjusting piece, and the shape and size of the window are the same as those of the chip;

[0041] The non - stick platform is provided with an adsorption hole array for vacuum - adsorbing the chip on the non - stick platform;

[0042] The non - stick platform is fixed to the base;

[0043] The adjusting piece is arranged between the non - stick platform and the base, and the adsorption hole array is opposite to the window.

[0044] As can be seen from the above description, the beneficial effects of the present utility model are as follows: a regulating piece is arranged between the anti-sticking platform and the base, and a window with the same shape and size as the chip is arranged on the regulating piece, while ensuring that the window is opposite to the adsorption hole array on the anti-sticking platform, so as to control the vacuum adsorption area of the adsorption hole array through the window of the regulating piece. In this way, it is not necessary to replace the anti-sticking platform according to the chip shape, and only the regulating piece with different window sizes needs to be replaced according to the chip shape, improving the applicability of the anti-sticking platform and reducing the use cost of the equipment.

[0045] Furthermore, a groove is arranged on one side of the anti-sticking platform close to the base;

[0046] Both ends of the groove are communicated; the regulating piece is arranged in the groove.

[0047] As can be seen from the above description, by arranging a groove on the anti-sticking platform and arranging the regulating piece in the groove, the regulating piece can be loaded and unloaded from the groove, facilitating the subsequent replacement of the regulating piece with different window sizes.

[0048] Furthermore, the regulating piece comprises a flat part and an extending part;

[0049] The window is arranged on the flat part;

[0050] The flat part is arranged in the groove and is attached to the first side of the base;

[0051] One end of the flat part is vertically connected to one end of the extending part to form an L-shaped structure, so that the extending part is attached to the second side of the base adjacent to the first side.

[0052] As can be seen from the above description, the regulating piece is arranged in an L-shaped structure, which is convenient for loading and unloading the regulating piece, and at the same time, the installation position of the flat part in the groove can be effectively limited through the extending part to ensure the window and the adsorption hole array.

[0053] Furthermore, a U-shaped opening is arranged on one side of the anti-sticking platform close to the extending part;

[0054] A positioning hole is arranged on the regulating piece;

[0055] The positioning hole is opposite to one end of the U-shaped opening close to the adsorption hole array, so that the center of the window and the center of the adsorption hole array are on the same straight line.

[0056] As can be seen from the above description, a U-shaped opening is arranged on the anti-sticking platform, a positioning hole is arranged on the regulating piece, and the U-shaped opening is opposite to the positioning hole, so as to ensure the relative position relationship between the adsorption hole array of the anti-sticking platform and the window of the regulating piece.

[0057] Furthermore, the depth of the groove is the same as the thickness of the regulating piece.

[0058] As described above, the depth of the groove is the same as the thickness of the adjusting piece, which ensures that the adjusting piece will not shift up and down during vacuum adsorption and at the same time ensures the vacuum adsorption effect.

[0059] Furthermore, the first projection area of the adsorption hole array on the base is located in the second projection area of the groove on the base.

[0060] As described above, since the adjusting piece is arranged in the groove, in order to ensure that the adsorption hole array can be opposite to the window, the adsorption hole array is arranged in the groove area.

[0061] Furthermore, the coverage area of the adsorption hole array is larger than the hollowed-out area of the window.

[0062] As described above, the coverage area of the adsorption hole array is larger than the hollowed-out area of the window, which improves the adaptability of the anti-sticking platform to windows of other sizes and at the same time ensures the adsorption effect of the adsorption hole array.

[0063] Furthermore, two threaded holes are provided on the anti-sticking platform;

[0064] The two threaded holes are respectively located on opposite sides of the groove;

[0065] The two threaded holes are used to fix the anti-sticking platform to the base.

[0066] As described above, the anti-sticking platform is fixed to the base by the cooperation of the threaded holes and screws, which facilitates the loading and unloading of the anti-sticking platform.

[0067] Furthermore, the adsorption holes in the adsorption hole array are arranged at equal distance intervals.

[0068] As described above, the adsorption hole array is arranged at equal distance intervals, so that the adsorption holes are evenly arranged, thus ensuring the uniform distribution of the vacuum adsorption force.

[0069] Furthermore, a convex edge is provided at the edge of the side of the anti-sticking platform close to the base;

[0070] The convex edge is in contact with the second side of the base.

[0071] As described above, by providing a convex edge at the edge of the anti-sticking platform, the relative position relationship between the anti-sticking platform and the base is restricted, avoiding the displacement of the anti-sticking platform and facilitating the installation of the anti-sticking platform.

The coverage area of the adsorption hole array 21 is larger than the hollow area of the window 11. The adsorption holes in the adsorption hole array 21 are arranged at equal distance intervals. Among them, the non-stick platform 2 covers the adjusting piece 1 and is fixed on the base, so that the adjusting piece 1 is fixed between the non-stick platform 2 and the base. The adsorption hole array 21 is arranged in a rectangular array, and the coverage area of the adsorption hole array 21 should be larger than the maximum size of the chip to be bonded, so as to increase the range of size adjustment of the window, thereby improving the applicability of the non-stick platform.

[0075] Please refer to Figure 3 , a groove 22 is provided on one side of the non-stick platform 2 close to the base. The depth of the groove 22 is the same as the thickness of the adjusting piece 1. The first projection area of the adsorption hole array 21 on the base is located in the second projection area of the groove 22 on the base. Two threaded holes 23 are provided on the non-stick platform 2; the two threaded holes 23 are respectively located on opposite sides of the groove 22; the two threaded holes 23 are used to fix the non-stick platform 2 to the base.

[0076] Please refer to Figure 4 , the adjusting piece 1 includes a flat part 101 and an extension part 102; the window 11 is provided on the flat part 101; the flat part 101 is arranged in the groove 22 and is in contact with the first side of the base; one end of the flat part 101 is vertically connected to one end of the extension part 102 to form an L-shaped structure, so that the extension part 102 is in contact with the second side of the base adjacent to the first side. Among them, both ends of the groove 22 are communicated, so that the air in the groove 22 can circulate, and the width of the groove 22 is greater than or equal to the width of the flat part 101, facilitating the insertion and extraction of the flat part 101 in the groove 22 and ensuring the convenience of replacing the adjusting piece 1. In addition, the first side and the second side of the base are vertically adjacent to form a corner, and the right angle of the L-shaped structure is in contact with the corner, so that the flat part 101 is in contact with the first side of the base and the extension part 102 is in contact with the second side of the base.

[0077] Please refer toFigure 3 and Figure 4 , on one side of the anti - sticking platform 2 close to the extension part 102, a U - shaped opening 24 is provided; on the flat part 101, a positioning hole 12 is provided; the positioning hole 12 is opposite to one end of the U - shaped opening 24 close to the adsorption hole array 21, so that the center of the window 11 and the center of the adsorption hole array 21 are on the same straight line.

[0078] Please refer to Figure 5 and Figure 6 , at the edge of one side of the anti - sticking platform 2 close to the base, a convex edge 25 is provided; the convex edge 25 fits with the second side of the base. Among them, the center of the positioning hole 12 and the center of the window 11 are on the same straight line. Since the extension part 102 of the adjusting piece 1 fits with the second side of the base, the longitudinal position of the center of the window 11 is defined. Then, through the relative relationship between the positioning hole 12 and the U - shaped opening 24, the transverse position of the center of the window 11 is defined, so as to ensure the relative position relationship between the window 11 and the adsorption hole array 21. In addition, the convex edge 25 is vertically arranged on the anti - sticking platform 2.

[0079] The installation steps of an anti - sticking fixture for a chip - sticking platform of the present utility model are specifically as follows: After installing the base on the chip - sticking platform, place the flat part of the adjusting piece in the area of the base provided with the vacuum adsorption cavity opening, and at the same time, fit the extension part of the adjusting piece with the base. After aligning the groove of the anti - sticking platform with the adjusting piece, the anti - sticking platform covers the adjusting piece and is placed on the base. Adjust the relative position between the anti - sticking platform and the base through the convex edge of the anti - sticking platform, and at the same time, adjust the relative position between the adsorption hole array and the window through the U - shaped opening of the anti - sticking platform and the positioning hole of the adjusting piece. After the relative position adjustment is completed, through the cooperation of the threaded hole of the anti - sticking platform and the screw, while fixing the anti - sticking platform to the base, the adjusting piece is fixed in the groove.

[0080] As Figure 7 shown, when the user needs to replace the chip, after loosening the screw fixing the anti - sticking platform, first pull out the old adjusting piece from the groove of the anti - sticking platform through the positioning hole, so that the extension part of the old adjusting piece is separated from the base, and then pull out the old adjusting piece from the groove through the extension part of the old adjusting piece. Finally, insert the flat part of the new adjusting piece with the same chip size into the groove of the anti - sticking platform, and after adjusting the window position through the extension part and the positioning hole, tighten the screw fixing the anti - sticking platform to complete the replacement of the adjusting piece.

[0081] In summary, a non-stick fixture for a chip bonding platform provided by the present utility model designs the original integrated special nano-coating material fixture into two parts: a non-stick platform and an adjusting piece. The adjusting piece is arranged between the non-stick platform and the base, and a window with the same shape and size as the chip is arranged on the adjusting piece, while ensuring that the window is opposite to the adsorption hole array on the non-stick platform, so as to control the vacuum adsorption area of the adsorption hole array through the window of the adjusting piece. When the user changes the chip size, there is no need to replace the non-stick platform according to the chip shape, but only need to replace the adjusting piece with different window sizes according to the chip shape, which improves the applicability of the non-stick platform and reduces the use cost of the equipment.
