一种芯片贴装视觉定位校准台

Abstract

本实用新型提供一种芯片贴装视觉定位校准台,包括：校准组件、视觉组件，所述校准组件包括台面，所述台面上表面左后侧在左右方向上以及右前侧在前后方向上分别嵌入安装有一个用于对芯片进行校准定位的推进件，所述台面上表面右后侧嵌入安装有一个用于对芯片进行定位的定位模具，与现有技术相比，本实用新型具有如下的有益效果：通过设置校准组件，搭配视觉组件，随着两个推动块进入定位槽并不断对内部的芯片进行推动，从而达到调节定位槽中芯片位置的目的，解决了芯片上料定位性较差导致机械臂在抓取时难以精准对准目标位置容易出现偏移或抓空现象，有助于提升芯片后续贴装的准确性。

Claims

2. A vision alignment table for chip mounting as claimed in claim 1, characterized in that: The upper surface of the platform (110) is recessed downward on the left rear side in the left-right direction and on the right front side in the front-back direction to form an embedding groove (111). The middle of the rear end of the platform (110) is inclined at 45 degrees to the middle of the right end to form a clearance groove (112).

3. The chip mounting visual positioning calibration stage as described in claim 2, characterized in that: The upper surface of the table (110) is recessed downward on the right rear side to form an installation groove (113). The clearance groove (112) extends from the rear end to the right side through the installation groove (113). The two embedding grooves (111) are respectively connected to the left side and the front side of the installation groove (113). The depth of the two embedding grooves (111) at the end away from the installation groove (113) is greater than the depth at the end closer to it.

4. A vision alignment table for chip mounting as defined in claim 3, wherein: The upper surface of the positioning mold (130) is recessed downward to form a positioning groove (131). The left side of the positioning groove (131) extends to the left to form a connecting groove one, and the front side of the positioning groove (131) extends forward to form a connecting groove two.

5. A vision alignment table for chip mounting as claimed in claim 4, wherein: The two embedded slots (111) are connected to the interior of the positioning slot (131) through connecting slot one and connecting slot two, respectively, and the depths of connecting slot one and connecting slot two are the same as the depths of the two embedded slots (111) near the mounting slot (113), and the depths of connecting slot one and connecting slot two are the same as the depths of the positioning slot (131).

6. A vision alignment table for chip mounting as defined in claim 5, wherein: The pusher (120) includes a cylinder (121), which is placed inside the end of the embedding groove (111) away from the mounting groove (113). The inner end of the cylinder (121) is fixedly connected to the outer end of the limiting block (122). The upper side of the limiting block (122) near the mounting groove (113) is fixedly connected to the outer end of the push block (123). The mounting groove (113) is a chip-shaped groove.

7. A vision alignment table for chip mounting as claimed in claim 6, wherein: The limiting block (122) is slidably installed inside the outer end of the embedding groove (111), and the height of its lower end is lower than the bottom height of the inner end of the embedding groove (111). The pushing blocks (123) on the two pushers (120) are slidably connected to the first and second connecting grooves, respectively.

8. A vision alignment table for chip mounting as recited in claim 2, wherein: Two optical fiber sensors (133) are installed in the middle of the rear end and the middle of the right end of the positioning mold (130) to assist the chip calibration positioning, and the two optical fiber sensors (133) are arranged at an angle of 45 degrees, and the two optical fiber sensors (133) are placed in the accommodation groove (112).
