It uses heat, pressure, and ultrasonic energy to tightly bond the bonding wires to the metal pads, enabling signal transmission between chips and between chips and the package. The wire bonding tool is an important tool in the wire bonding process, and its performance determines the reliability of the bonding.

[0003] Currently, for wire bonding of small chips and small electrodes, such as chips with dimensions of 4mil×5mil and 3.3mil×5mil, and electrodes with dimensions of 38 micrometers, 40 micrometers or smaller, ceramic chamfers are generally used. The taper angle of the ceramic chamfer is a key design parameter that directly affects the performance of the chamfer in semiconductor packaging, such as welding accuracy, service life, and material wear resistance. When processing the chamfer, the taper angle needs to be ground. For example, Chinese Patent Publication No. CN215092888U discloses "a grinding mechanism for grinding the inner chamfer of a ceramic chamfer". Through the movement of the first moving component and the second moving component, it is convenient to drive the grinding wheel and the loading clamp to move, thereby providing a grinding mechanism for grinding the inner chamfer of a ceramic chamfer and improving the grinding accuracy of the inner chamfer of the ceramic chamfer.

[0004] However, in actual use, due to the high hardness of the ceramic chopping knife itself, the grinding wheel of the grinding mechanism needs to be replaced frequently. The replacement is inconvenient and usually requires the use of tools to remove and install the grinding wheel, which affects the efficiency of replacement and processing. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-5 A ceramic chopping knife cone angle grinding device includes a machine base 1, a mounting cover 2 on the machine base 1, multiple sleeves 3 fixedly mounted on the mounting cover 2, and a chopping knife mounting seat 4 rotatably mounted inside each sleeve 3. A motor is mounted on the machine base 1, a first gear is fixedly mounted on the output shaft of the motor, and a second gear is mounted on each mounting seat 4 that meshes with the first gear. The motor drives the multiple mounting seats 4 and the chopping knife to rotate for convenient grinding. A support base 5 is fixedly mounted on the machine base 1, a grinding table 6 is slidably mounted on the support base 5, a grinding unit 7 that cooperates with the cone angle of the chopping knife is mounted on the grinding table 6, and a linear motor 8 is fixedly mounted on the support base 5. The output shaft of the linear motor 8 is connected to the grinding table 6.

[0017] In this invention, the position of the grinding table 6 is controlled by the linear motor 8 to grind or remove the grinding of the cleaver. By setting up the grinding unit 7 and the grinding table 6 to cooperate, when changing the grinding head, the grinding unit 7 can be taken out as a whole for replacement. Compared with the original replacement of the small grinding head, the operation is simpler and faster.

[0018] Furthermore, in this embodiment, the polishing table 6 is provided with a receiving groove 61, the polishing unit 7 is disposed in the receiving groove 61, and the polishing table 6 is provided with a clamping mechanism 9 that cooperates with the receiving groove 61 and the polishing unit 7. The polishing unit 7 is clamped and fixed as a whole by the clamping mechanism 9, thereby ensuring that the polishing unit 7 will not move during polishing and cause polishing failure.

[0019] Furthermore, in this embodiment, the clamping mechanism 9 includes a clamping block 91. Both the clamping block 91 and the receiving groove 61 are provided with slots 92 that cooperate with the grinding unit 7. A slider 93 is fixedly provided on the clamping block 91, and a sliding groove corresponding to the slider 93 is provided on the receiving groove 61. The clamping block 91 can move horizontally along the direction of the sliding groove, thereby removing the grinding unit 7 clamped by the clamping block 91 for replacement, and also making it convenient to reset the clamping block 91 to fix the grinding unit 7.

[0020] It should be noted that, in this embodiment, the slot 92 of the receiving groove 61 is provided with an installation hole, and a spring 94 is fixedly connected in the installation hole. A top block 95 is fixedly connected to the spring 94. The top block 95 abuts against the grinding unit 7. After the grinding unit 7 is installed, the top block 95 is squeezed into the installation hole by the grinding unit 7. At the same time, the spring 94 is compressed and produces elastic deformation. When the clamping block 91 releases its grip on the grinding unit 7, the spring 94 drives the top block 95 to move and push the grinding unit 7 to move, pushing the grinding unit 7 out of the slot 92 for easy removal and replacement.

[0021] Furthermore, in this embodiment, a lifting groove is provided in the sliding groove, and a wedge block 96 is slidably arranged in the lifting groove. An elastic element 97 is provided between the wedge block 96 and the lifting groove. A guide groove is provided on one side of the lifting groove. A toggle part 98 that cooperates with the guide groove is fixedly provided on the wedge block 96. The position of the wedge block 96 can be controlled by moving the toggle part 98 up and down. When the wedge block 96 fixes the clamping block 91, it contacts one end of the clamping block 91 to limit its movement.

[0022] More specifically, in this embodiment, the grinding unit 7 includes a fixing part 71 and a grinding head 72. A tool handle is fixedly provided on one side of the grinding head 72. A slot corresponding to the tool handle is provided on the fixing part 71. A locking block corresponding to the slot and the tool handle is provided on the fixing part 71. The locking block is fixedly connected to the fixing part 71 by screws, thereby tightly combining the tool handle and the fixing part 71 to form an integral structure. When replacing the grinding head 72, the locking block is moved up or removed first, and then the grinding head 72 and the tool handle can be removed for replacement.

[0023] Working method: During operation, the position of the grinding table 6 is controlled by the linear motor 8 to grind or remove the grinding of the cutting tool. The wedge block 96 is moved down by the downward moving part 98, so that the wedge block 96 is separated from the clamping block 91. The clamping block 91 is moved to separate the two slots 92. The spring 94 drives the top block 95 to move and push the grinding unit 7 to move, pushing the grinding unit 7 out of the slot 92. The grinding unit 7 can then be taken out for replacement. The operation is simple and convenient. After installing the new grinding unit 7, the clamping block 91 is reset to fix the grinding unit 7.
