Description

Technical Field

[0001] The present invention relates to the technical field of grinding devices, and particularly to a grinding jig for a die bonder.

Background Art

[0002] In the current technology, it is common to use a dedicated jig for polishing flanges provided by DISCO Corporation of Japan, which is a die bonder manufacturer. In any die bonder, a professional technician is required to polish the flange, and it takes about 100 minutes to complete one polishing. This is mainly because the workbench needs to be removed for flange polishing, the flat workbench needs to be cleaned after polishing, and in addition, it is necessary to measure and adjust the accuracy of the workbench. If the error of the flange exceeds 2 microns, defective products will occur. Therefore, the requirement for the polishing accuracy of the flange is very high, and polishing also takes a very long time. For semiconductor manufacturers that must continue production, it is impossible to take a long time to polish the flange after replacing the blade every time.

[0017] Embodiment 1 As shown in FIGS. 1-3, this embodiment provides a polishing jig for a die bonder. The die bonder has a main shaft 1, and a flange 2 for attaching a cutting tool is connected to the main shaft 1. The flange 2 has a light axis section 22 arranged in the axial direction. The polishing jig includes a torque output device 5 and a polishing member clamping device. The polishing member clamping device has a clamping body 4. One end of the clamping body 4 is detachably connected to the torque output device 5, and a polishing member 3 used for polishing the light axis section 22 is installed at the other end of the clamping body 4. The rotational motion output from the torque output device 5 is transmitted to the polishing member clamping device. Under the rotational motion of the polishing member clamping device that is interlocked therewith, the polishing member 3 quickly polishes the light axis section 22 of the flange 2. The torque output device 5 is selected from conventional electric torque wrenches. The clamping body 4 is provided with a non-circular hole structure, such as a polygonal hole. The output shaft of the torque output device 5 is provided with a non-circular shaft structure that fits with the non-circular hole structure, that is, a polygonal shaft corresponding to the polygonal hole. The torque output device 5 is inserted into the non-circular hole structure through the output shaft to achieve torque transmission of the clamping body 4. Therefore, rapid insertion connection is realized, and installation and removal are very convenient.

[0018] By providing at least one first recess on the clamping body 4, the polishing member 3 is arranged. The number of the first recesses is set according to requirements. For example, in this embodiment, four first recesses are arranged in the circumferential direction along the axis. The polishing member 3 is installed in the first recess. Specifically, a tightening member such as a screw is provided on the clamping body 4. The tightening member is screwed with the clamping body 4, and the end of the tightening member abuts against the outer surface of the polishing member 3, thereby fixing the polishing member 3 in the first recess.

[0019] The polishing member 3 has a first polishing portion 31 arranged in the axial direction. The first polishing portion 31 protrudes from the clamping body 4. In order to polish the light axis section 22, the first polishing portion 31 can move along the axial direction of the light axis section 22. The polishing member 3 may be a rectangular parallelepiped, and the first polishing portion 31 may be arranged at the lower part of the rectangular parallelepiped. The length of the first polishing portion 31 only needs to be wider than the width of the light axis section 22.

[0020] In order to enable the first polishing member 31 of the polishing member 3 to rotate around the axis of the optical axis step 22, in this embodiment, the flange 2 has a male screw step 23 arranged in the axial direction, and the clamping body 4 is provided with a female screw step 41 that meshes with the male screw step 23. When the female screw step 41 meshes with the male screw step 23, the screwing is a mechanical operation that combines axial movement with rotational movement. Therefore, when the clamping body 4 rotates, its movement realizes rotation and axial movement, and thus the polishing member 3 can move and rotate along the optical axis step 22, and polishing is applied to the optical axis step 22. By screwing, it is ensured that the rotation of the polishing member 3 along the axis is achieved, without affecting the torque output device 5, and the polishing accuracy can be guaranteed.

[0021] Embodiment 2 As shown in FIGS. 4-5, the polishing jig of the die-attaching machine according to this embodiment is The flange 2 has an end face portion 21 arranged in the radial direction, the polishing member 3 further has a second polishing portion 32 arranged in the radial direction. When the first polishing portion 31 moves to the opposite side of the optical axis step 22, the second polishing portion 32 can apply polishing to the end face portion of the flange 2, whereby the optical axis step 22 and the end face can be polished simultaneously. In addition, the polishing member 3 may be in the shape of a rectangular parallelepiped, clamping is applied in the radial direction of the rectangular parallelepiped, the second polishing portion 32 is installed on the side surface in the longitudinal direction, the end face of the flange 2 can be polished, the first polishing portion 31 is installed on the end face in the width direction, and the optical axis step 22 can be polished, which is different from Embodiment 1.

[0022] Embodiment 3 As shown in FIG. 6, the polishing jig of the die-attaching machine according to this embodiment is The clamping body 4 is provided with a second recess, the polishing member 3 is arranged in the second recess, the polishing member 3 has a polishing portion with a circular recess structure, and cooperates with the optical axis step 22 to apply polishing to the optical axis step 22. The inner contour of the second recess coincides with the outer contour of the polishing member 3, and it is possible to use a pressure device to press the polishing member 3 into the second recess by interference fit. In order to prevent the polishing member 3 from slipping out of the second recess during use, a tightening member is provided on the clamping body 4. The tightening member is screwed with the clamping body 4, and the end of the tightening member abuts against the outer surface of the polishing member 3, thereby fixing the polishing member 3 in the second recess, which is different from Embodiment 1.
