Description

Technical Field

[0001] This utility model relates to the field of dicing machine technology, specifically to a precision feeding box for dicing machines. Background Technology

[0002] Dicing machines are key pieces of equipment in the semiconductor manufacturing and microelectronics packaging fields. They are mainly used to precisely cut integrated circuit chips on wafers into individual chip particles, preparing them for subsequent packaging and testing processes. The dicing bin in a dicing machine is a container used to store wafer workpieces after processing.

[0003] Existing dicing machine feed boxes, such as the fully automatic dicing machine feed box disclosed in publication number CN218614810U, have the advantage of buffering the wafers during the process of falling into the feed box. However, this feed box is inconvenient for positioning the wafer workpiece before feeding and for preventing the wafer workpieces from falling and causing collisions between the workpieces. Therefore, we propose a precision feed box for dicing machines. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a precision feeding box for a dicing machine.

[0024] Example 1:

[0025] Combination Figure 1-3 As shown, the present invention provides a precision feeding box for a dicing machine, comprising: a feeding box body 100 and a feeding assembly 200; the feeding box body 100 includes a chassis 101 fixedly mounted at its bottom; the feeding assembly 200 includes an electric slide rail 201 fixedly mounted on one side of the chassis 101, a slider 202 movably mounted on the electric slide rail 201, a first motor 203 fixedly mounted at the outer end of the slider 202, a support plate 204 fixedly mounted on the top of the first motor 203, a right positioning ring 205 and a left positioning ring 206 movably mounted on the top two sides of the feeding box body 100 respectively, a right gear 207 and a left gear 208 fixedly mounted on one side of the bottom of the right positioning ring 205 and the left positioning ring 206 respectively, and a right gear 207 and a left gear 208 fixedly mounted on the bottom of the right gear 207. The second motor 209 and the support plate 210 fixedly installed at the bottom of the second motor 209 are respectively fixedly installed on the bottom and side walls of the feeding box body 100, and the feeding box body 100 is also provided with a holding port 214 at the bottom. The left gear 208 is also fixedly installed with a rotating shaft 215 at the bottom. A baffle 216 is also fixedly installed on the rotating shaft 215. The support plate 210 is also provided with an insertion hole 217, and the rotating shaft 215 is movably installed in the insertion hole 217. The rotating shaft 215 is also provided with a threaded hole 218, and a screw 219 is movably installed in the threaded hole 218. The support plate 210 is fixed to the outer wall of the feeding box body 100.

[0026] Specifically, the dicing machine is a key piece of equipment in the semiconductor manufacturing and microelectronics packaging fields. It is mainly used to precisely dice integrated circuit chips on wafers into individual chip particles, preparing them for subsequent packaging and testing processes. The unloading bin in the dicing machine is a storage bin for wafer workpieces after processing. When the workpiece is conveyed to the unloading bin body 100, it is first conveyed to the upper end of the support plate 204 at the top of the unloading bin body 100. After being clamped and positioned by the right positioning ring 205 and left positioning ring 206 on both sides of the support plate 204, it is then moved downwards by the support plate 204 driven by the electric slide rail 201 to ensure accurate unloading into the unloading bin body 100. Simultaneously, the downward movement of the support plate 204 driven by the electric slide rail 201 also prevents collisions between the workpiece and other workpieces in the unloading bin body 100 during unloading, thus protecting the workpiece from damage. The lower outer part of the support plate 204... A motor 203 is mainly used for the rotation of the support plate 204 after the workpiece is unloaded, so that the workpiece can be moved out through the lower end. The second motor 209 at the upper end of the support plate 210 mainly drives the right gear 207 to synchronously drive the outer left gear 208, thereby realizing the opening and closing adjustment of the right positioning ring 205 and the left positioning ring 206. The first buffer pad 211 installed at the upper and lower ends of the support plate 204 is mainly used to protect the workpiece during the receiving and unloading process. The bottom wall and side wall of the unloading box body 100 are also used for this purpose. The second buffer pad 212 and the third buffer pad 213 are mainly used for protection during workpiece unloading and collection. The holding port 214 at the bottom of the unloading box body 100 is mainly used to facilitate the removal of multiple sets of workpieces from the unloading box body 100 by arm. The rotating shaft 215 installed in the insertion hole 217, as well as the baffle 216 and screw 219 installed on the rotating shaft 215, are mainly used for binding and supporting the rotating shaft 215, thereby ensuring the stability of the left gear 208 and the left positioning ring 206 during rotation adjustment.

[0027] Working principle and usage process of this utility model:

[0028] After the workpiece processed in the dicing machine is conveyed to the upper end of the support plate 204 at the top of the unloading box body 100, the second motor 209 at the upper end of the support plate 210 is started. After the second motor 209 is started, it will drive the upper right gear 207 to rotate. After the right gear 207 rotates, it will synchronously drive the outer meshing left gear 208 to rotate synchronously, thereby synchronously opening and closing the right positioning ring 205 and the left positioning ring 206 on both sides of the support plate 204. The workpiece at the upper end of the support plate 204 is clamped by the closed right positioning ring 205 and the left positioning ring 206 to position the workpiece received at the upper end of the support plate 204. After the right positioning ring 205 and the left positioning ring 206 position the workpiece, the workpiece is then... The second motor 209 controls the right positioning ring 205 and the left positioning ring 206 to open and return to their original positions. After the workpiece at the upper end of the support plate 204 is positioned, the electric slide rail 201 is started to move the first motor 203, the support plate 204, and the workpiece at the upper end of the support plate 204 downwards via the slider 202. After the support plate 204 moves down to the top of other workpieces in the unloading box body 100, the first motor 203 can rotate the support plate 204 to move the support plate 204 out. After the support plate 204 is moved out, the electric slide rail 201 moves the support plate 204 back to its original position, and the first motor 203 is started to reselect the support plate 204 to the middle of the unloading box body 100 for subsequent workpiece unloading.

[0029] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
