Abstract
Description
Technical Field
[0001] This utility model belongs to the field of AMB ceramic copper-clad laminate application technology, specifically, it relates to a positioning fixture for AMB ceramic copper-clad laminate. Background Technology
[0002] AMB ceramic copper-clad laminate is a high-performance ceramic circuit board. It is formed by brazing copper sheets and silicon nitride, aluminum nitride, aluminum oxide, or silicon carbide with active solder to form a motherboard, which is used for complex circuit design and high-requirement process manufacturing applications.
[0003] During the application of AMB ceramic copper-clad laminates, positioning fixtures are required for positioning to facilitate the handling of AMB ceramic copper-clad laminates in various processes. Existing positioning fixtures are basically stacked in a clip-type placement frame according to their layer height. When a positioning fixture is needed, a robotic arm uses a fixture suction nozzle to pick it up. Due to the stacking of the fixtures, they stick together and cannot be easily detached. Picking up multiple positioning fixtures at once requires manual intervention, which not only occupies manpower but also affects production efficiency. Furthermore, after the reflow soldering process of AMB ceramic copper-clad laminates, the positioning fixtures need to be separated from the AMB ceramic copper-clad laminates. However, the positioning fixtures sometimes jam the AMB ceramic copper-clad laminates, causing the ceramic edges to crack and the product to be scrapped. Therefore, improvements are necessary.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] One embodiment of this application provides a positioning fixture for an AMB ceramic copper-clad laminate, such as... Figures 1-3 As shown, it includes: a jig body 1, which is elongated, with the right end of the jig body 1 extending downward to form a first limiting block 11, the outer side of the first limiting block 11 being flush with the right side of the jig body 1; the thickness of the first limiting block 11 being the same as the thickness of the jig body 1; the bottom end of the first limiting block 11 being planar; the bottom of the first limiting block 11 extending inward to form a first limiting protrusion 12; the end face of the first limiting protrusion 12 being an arc surface to avoid damaging the ceramic edge of the AMB ceramic copper-clad laminate; a first rounded corner 13 being formed between the bottom of the first limiting protrusion 12 and the bottom of the first limiting block 11 to avoid damaging the ceramic edge of the AMB ceramic copper-clad laminate during disassembly.
[0028] The left end of the fixture body 1 extends downward to form a second limiting protrusion 14, the thickness of which is the same as the thickness of the fixture body 1; the end face of the second limiting protrusion 14 is an arc surface to avoid damaging the ceramic edge of the AMB ceramic copper-clad laminate; a second rounded corner 15 is formed between the bottom of the second limiting protrusion 14 and the bottom of the fixture body 1 to avoid damaging the ceramic edge of the AMB ceramic copper-clad laminate during disassembly.
[0029] A second limiting block 16 extends downward from the fixture body 1, and the second limiting block 16 is close to the second limiting protrusion 14; the thickness of the second limiting block 16 is the same as the thickness of the fixture body 1; the end face of the second limiting block 16 is an arc surface to avoid damaging the ceramic edge of the AMB ceramic copper-clad laminate; the end face of the second limiting block 16 is lower than the end face of the first limiting block 11; the end face of the second limiting block 16 is higher than the end face of the second limiting protrusion 14; the left and right sides of the second limiting block 16 are connected to the fixture body 1 through inclined surfaces 17 to ensure the stability of the second limiting block 16.
[0030] Furthermore, such as Figure 3 As shown, a third rounded corner 18 is formed between the bottom of the second limiting block 16 and the bottom of the fixture body 1, which can prevent damage to the ceramic edge of the AMB ceramic copper-clad laminate during disassembly.
[0031] Specifically, such as Figures 1-3 As shown, at least one third limiting protrusion 19 extends from the fixture body 1, and multiple third limiting protrusions 19 are spaced apart; the third limiting protrusion 19 is located between the first limiting block 11 and the second limiting block 16; the thickness of the third limiting protrusion 19 is the same as the thickness of the fixture body 1; the end face of the third limiting protrusion 19 is an arc surface to avoid damaging the ceramic edge of the AMB ceramic copper-clad laminate, and the end face of the third limiting protrusion 19 is on the same plane as the end face of the second limiting protrusion 14; a fourth rounded corner 110 is formed between the bottom of the third limiting protrusion 19 and the bottom of the fixture body 1 to avoid damaging the ceramic edge of the AMB ceramic copper-clad laminate during disassembly.
[0032] In one embodiment, such as Figures 1-3 As shown, a first limiting groove 111 is formed on the fixture body 1, and a first boss 112 is formed on the back of the fixture body 1 at a position corresponding to the first limiting groove 111. When multiple positioning fixtures are stacked, the first boss 112 of the previous positioning fixture cooperates with the first limiting groove 111 of the next positioning fixture to achieve relative positioning of the stack. The first limiting groove 111 is a circular groove, and the first boss 112 is a cylinder.

The second limiting groove 113 is a circular groove, and the second protrusion 114 is a polygonal column, which plays a role in preventing mistaken identity.
[0034] Furthermore, the end faces of the first limiting groove 111, the first boss 112, the second limiting groove 113, and the second boss 114 are all designed with rounded corners.
[0035] In one embodiment, such as Figure 3 As shown, the back of the fixture body 1 is provided with one or more elongated grooves 115. One end of the elongated groove 115 extends through to the upper end face of the fixture body 1. The elongated groove 115 allows a certain amount of air to enter. When multiple positioning fixtures are stacked, it can effectively prevent adjacent positioning fixtures from sticking together, which is convenient for the robot to pick up.
[0036] When using, such as Figure 4 As shown, multiple positioning fixtures are connected to the base at preset positions. The positioning fixtures limit the AMB ceramic copper-clad laminate to facilitate its processing. This is existing technology and will not be described in detail here.
