Description

Technical Field

[0001] This utility model belongs to the field of microelectronic packaging technology, and in particular relates to an automatic bonding fixture compatible with multiple product sizes. Background Technology

[0002] In microelectronic packaging processes, existing automated bonding fixtures can only meet the automated bonding requirements of one type of product. When the product size changes, the machining tooling needs to be redesigned, leading to increased costs and reduced work efficiency. On the other hand, existing fixtures usually use mechanical fixing to clamp the product. When the product size is small, there may not be enough space for the mechanical clamping jaws, or the jaws may interfere with the bonding machine, affecting the product bonding.

[0003] Therefore, addressing the shortcomings of the existing technologies has become the focus of efforts for those skilled in the field. Utility Model Content

[0004] The purpose of this invention is to provide a glue sealing and pressure fixture that can completely solve the shortcomings of the prior art.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An automatic bonding fixture compatible with multiple product sizes includes a base, a tray positioning frame, a tray, and a product positioning frame. The base has multiple first air holes, and a first groove is formed on the bottom surface of the base to connect the multiple first air holes. The tray positioning frame is stacked on the top surface of the base, and the tray positioning frame has multiple positioning openings corresponding to the first air holes. The tray is placed in the positioning openings. The tray has multiple second air holes, and a second groove is formed on the bottom surface of the tray to connect the multiple second air holes. The second groove corresponds to the first air holes. The product positioning frame is stacked on the top surface of the tray, and a product positioning hole is formed on the product positioning frame.

[0007] Preferably, multiple sets of the tray and product positioning frame are provided.

[0008] Preferably, the second air hole on the tray is a cross-shaped air hole.

[0009] Preferably, the second air hole on the tray is a king-shaped air hole.

[0010] Compared with the prior art, the advantages of this utility model are: simple structure, reasonable design, simple and convenient operation, low cost, applicable to the automatic bonding needs of products of different sizes and thicknesses, which helps to improve work efficiency.

[0021] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0022] like Figures 1 to 10 As shown, an automatic bonding fixture compatible with multiple product sizes includes a base 1, a tray positioning frame 2, a tray 3, and a product positioning frame 4. The base 1 has multiple first air holes 5, and a first groove 6 is formed on the bottom surface of the base 1 to connect the multiple first air holes 5. The tray positioning frame 2 is stacked on top of the base 1, and has multiple positioning openings 7 corresponding to the first air holes 5. The tray 3 is placed in the positioning openings 7. The tray 3 has multiple second air holes 8, and a second groove 9 is formed on the bottom surface of the tray 3 to connect the multiple second air holes 8, with the second groove 9 corresponding to the first air holes 5. The product positioning frame 4 is stacked on top of the tray 3, and has product positioning holes 10. The base 1 and the tray positioning frame 2, as well as the tray 3 and the product positioning frame 4, can be connected and fixed with screws.

[0023] To accommodate the automated bonding requirements of products of different sizes and thicknesses, multiple sets of trays 3 and product positioning frames 4 are provided. Each set of trays 3 and product positioning frames 4 is designed with different sizes and thicknesses for different products, and the second air hole 8 is designed with a different structure. By replacing different trays 3 and product positioning frames 4, the automated bonding requirements of products of different sizes and thicknesses can be met. The worktable space of the bonding machine is limited; if the product thickness is too large, coupled with the height of the fixture, interference can easily occur, affecting the bonding process. Interference can be avoided by using trays and product positioning frames with a smaller thickness.

[0024] In this embodiment, the second air hole 8 on the tray 3 is a cross-shaped air hole, or it can be a king-shaped air hole.

[0025] When in use, this fixture is set on the bonding machine, the product 11 is placed in the product positioning hole 10, and the negative pressure is used to fix the product 11 on the product positioning frame 4 through the interconnected first groove 6, first air hole 5, second groove 9 and second air hole 8, and then the bonding work can be carried out.

[0026] This utility model has a simple structure, reasonable design, simple and convenient operation, and low cost. It can be applied to the automatic bonding needs of products of different sizes and thicknesses, which helps to improve work efficiency.

[0027] Similarly, it should be understood that, in order to simplify this disclosure and aid in understanding one or more of the various aspects of the invention, in the above description of exemplary embodiments of the invention, various features of the invention are sometimes grouped together in a single embodiment, figure, or description thereof. However, this method of disclosure should not be interpreted as reflecting an intention that the claimed invention requires more features than are expressly recited in each claim. Rather, as reflected in the following claims, the inventive aspect lies in fewer than all features of a single foregoing disclosed embodiment.
