Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor packaging equipment, in particular to a LidAttach hot pressing die quick fixing fixture device. Background Art

[0002] The LidAttach (chip package cap) hot stamping die fast fixturing fixture is a fixture used to quickly secure hot stamping dies during chip packaging testing, package soldering, and other processes. Its primary function is to quickly attach the hot stamping die to the fixture and precisely position it through screw adjustment and machining to ensure a perfect fit between the die and the chip, thereby improving the quality and efficiency of chip packaging.

[0003] LidAttach is a key step in the semiconductor packaging process. It involves fixing a metal or ceramic lid (Lid) on top of the chip through hot pressing to protect the chip from the external environment. However, the widely used LidAttach equipment on the market mostly uses screws to fix the hot pressing mold. This fixing method requires a lot of time to remove and install the screws every time the mold is changed, which not only increases the complexity of the operation but also seriously restricts the improvement of production efficiency. Therefore, we proposed a LidAttach hot pressing mold fast fixing fixture device. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0005] Specifically, the technical problem to be solved by the present invention is to provide a LidAttach hot pressing mold quick fixing fixture device to solve the technical problem of low mold changing efficiency caused by fixing the hot pressing mold by screws in the existing technology.

[0011] A hot pressing die, the hot pressing die being arranged on the push rod of the multi-stage hydraulic push rod;

[0012] A snap-on locking structure is provided on the positioning seat and the hot pressing die, and is used to lock and unlock the positioning seat and the hot pressing die.

[0013] As an improved technical solution, positioning holes are provided at the four corners of the top end of the positioning seat, and the inner cavity of the positioning holes is movably connected to the hot pressing mold.

[0014] As an improved technical solution, positioning pins are fixedly installed at the four corners of one end of the hot pressing die away from the multi-stage hydraulic push rod, and the outer surface of the positioning pins is movably engaged with the inner cavity of the positioning hole.

[0016] As an improved technical solution, the snap-on locking structure includes a lower fixed plate, which is fixedly connected to the outer surface of the positioning seat, and a first T-shaped clamping column is fixedly installed on the outer surface of the lower fixed plate. A rotating plate is provided on the outer surface of the first T-shaped clamping column, and a second T-shaped clamping column is fixedly installed on the outer side of one end of the rotating plate away from the first T-shaped clamping column.

[0017] As an improved technical solution, the snap-on locking structure also includes an upper fixed plate, which is fixedly connected to the outer surface of the lower mold on the hot pressing mold. An inverted L-shaped clip is fixedly installed on the outer surface of the upper fixed plate, and the inverted L-shaped clip is movably connected to the rotating plate and movably connected to the second T-shaped clip column.

[0019] After adopting the above technical solution, the beneficial effects of the utility model are:

[0020] 1. The utility model locks the positioning seat and the lower mold on the hot pressing mold on the base by utilizing a snap locking structure. At this time, the rotating plate rotates clockwise with the first T-shaped clamping column as the axis until the rotating plate is rotated and clamped between the upper fixed plate and the inverted L-shaped clamping plate, and the second T-shaped clamping column is clamped on the inverted L-shaped clamping plate to achieve rapid and firm locking of the hot pressing mold and the positioning seat. During this period, the locking of the lower mold on the hot pressing mold and the positioning seat can be intuitively confirmed, thereby achieving rapid installation of the hot pressing mold and reducing the difficulty and complexity of operation.

[0021] 2.

[0044] Example 2

[0045] Reference Figure 1 -3 is the second embodiment of the present utility model. This embodiment differs from the first embodiment in that:

[0046] The snap-on locking structure 6 includes a lower fixed plate 61, which is fixedly connected to the outer surface of the positioning seat 2. A first T-shaped clamping column 62 is fixedly installed on the outer surface of the lower fixed plate 61. A rotating plate 63 is provided on the outer surface of the first T-shaped clamping column 62.
