Description

Technical Field

[0001] The present invention relates to the technical field of component mounting, and particularly to a positioning jig for a cutting tool cooling nozzle of a die bonding machine.

Background Art

[0002] An existing die bonding machine is equipped with a cutting tool and a nozzle for cooling the cutting tool. When cutting a chip, the cutting tool causes a high temperature. If the temperature is too high, the cutting tool is likely to deform, affecting the cutting accuracy. Therefore, a nozzle is installed to spray a coolant onto the cutting tool to cool the cutting tool and lower the temperature. However, since the entire die bonding machine generates a certain vibration during operation, after working for a while, the screws fixing the nozzle are likely to loosen. When the screws loosen, the spraying position of the nozzle is likely to shift, thereby making it impossible to sufficiently cool the cutting tool. Therefore, it is necessary to reposition and fix the nozzle. The existing method mainly determines the position of the nozzle by the visual inspection of technicians or with the aid of tools, but it is very difficult to align the position of the nozzle to the standard height during actual operation.

Brief Description of the Drawings

Figure 4

[0017] As shown in FIGS. 1-2, the die attaching machine according to the present invention has a die attaching machine body 100, a main shaft 110 for attaching a tool is installed in the middle part of the die attaching machine body 100, and the die attaching machine body 100 is connected to at least one cooling nozzle. In the die attaching machine targeted in this embodiment, a first cooling nozzle 120 and a second cooling nozzle 130 are installed. The first cooling nozzle 120 is located on one side of the main shaft 110, the second cooling nozzle 130 is located on the other side of the main shaft 110, and two second cooling nozzles 130 are arranged in parallel along the axial direction of the main shaft 110.

[0018] The positioning jig for the tool cooling nozzle according to the present invention includes a jig body 210. The jig body 210 has a fitting ring portion 212 and a flat portion 211. The fitting ring portion 212 is integrally formed with the flat portion 211 or detachably separated and arranged. The fitting ring portion 212 has a circular cavity fitted to the main shaft 110, and the circular cavity is slightly larger than the outer diameter of the main shaft 110. The flat portion 211 is provided with a calibration plane for calibrating the cooling nozzle. When the calibration plane contacts the cooling nozzle, the mounting position of the cooling nozzle is determined, and the rapid positioning of the cooling nozzle is achieved.

[0019] Since there is a height difference between the first cooling nozzle 120 and the first cooling nozzle 130 and the calibration plane, in order to position the two cooling nozzles simultaneously, the positioning jig for the cooling nozzle of this embodiment further includes a height adjustment member 220. The height adjustment member 220 is arranged on the calibration plane, thereby adjusting the positioning height of the cooling nozzle. The height adjustment member 220 may be integrally formed with the flat portion 211. If the height of the cooling nozzle is predetermined, it is integrally formed with the flat portion 211 in advance. Of course, the height adjustment member 220 may be separately arranged from the flat portion 211, and the height adjustment member 220 may be arranged after the jig body 210 is positioned.

[0020] Since the fitting ring portion 212 having a circular cavity structure in the jig body 210 is connected to the main shaft 110, even if the positioning of the cooling nozzle is achieved (for example, maintaining a vertical state by its own weight), such positioning is very unstable because the jig body 210 is not positioned in the circumferential direction of the main shaft 110. In order to improve the stability of the jig body 210, the positioning jig for the cooling nozzle of this embodiment further includes a position limiting member 230. The position limiting member 230 is detachably connected to the die attaching machine body 100. The position limiting member 230 is provided with a position limiting portion for contacting the flat portion 211, and under the limitation of the position limiting portion, the jig body 210 can rotate around the main shaft 110.

[0021] Specifically, as shown in FIG. 4, at least two position limiting protrusions 231 are provided on the position limiting member 230, and the position limiting protrusions 231 are inserted into the position limiting holes 140 of the die attaching machine body 100 to play a role in position limitation. The position limiting holes 140 of the die attaching machine body 100 may be two horizontally arranged screw holes. After installing the flat head screws, there remains a certain depth of the holes, and the two position limiting protrusions 231 are also inserted to complete the positioning of the position limiting member 230. After positioning the position limiting member 230, by bringing the position limiting part of the position limiting member 230 into contact with the flat platform part 211, the jig body 210 rotates around the main shaft 110 under the limitation of the position limiting part, thereby realizing stable positioning. In another aspect of the present invention, at least two position limiting holes are provided in the position limiting member 230, and the position limiting protrusions of the die attaching machine body 100 are fitted into the position limiting holes to play a role in position limitation. The position limiting protrusions can be screws protruding from the die attaching machine body 100 or other protrusion structures.

[0022] To facilitate the position limitation between the position limiting member 230 and the flat platform part 211, a position limiting groove 2110 is provided on the flat platform part 211, and the position limiting member 230 is inserted into the position limiting groove 2110, and under their limitation, the jig body 210 rotates around the main shaft 110.

[0023] The second cooling nozzles 130 of the die attaching machine according to the present invention are arranged in parallel, have a rather long structure, and perform jet cooling at both ends approaching the cutting tool respectively. Therefore, the connection part between the fitting ring part 212 and the flat platform part 211 of the jig body 210 is pushed between the two second cooling nozzles 130. With such a structure, even if the positioning of the second cooling nozzles 130 is completed using the jig body 210, it becomes difficult to remove the jig body 210 after the positioning is completed.

[0024] As shown in FIG. 3, to facilitate the removal of the jig body 210, the fitting ring part 212 has at least two separable annular structures, and the fitting ring part 212 is detachably connected between the annular structures.

[0025] Specifically, a structure is provided in which a dovetail groove between the annular structures is removably combined with a dovetail protrusion, and the dovetail groove and the dovetail protrusion are arranged in the axial direction of the main shaft 110. Of course, the combination of a T-shaped groove and a T-shaped protrusion can also be used. With such a combined structure, after positioning the cooling nozzle, first move the upper annular structure along the axial direction of the main shaft 110 to remove it from the original position. When the dovetail protrusion comes out of the dovetail groove, the lower annular structure, if it communicates with the platform portion 211, may directly move downward and be removed, facilitating removal without being affected by the positions of the two second nozzles.
