Description

Technical Field

[0001] This utility model relates to the field of electronic packaging technology, specifically to a pressure plate fixture for a packaging bonding machine. Background Technology

[0002] The clamping fixtures in packaging and bonding equipment play a crucial role in modern semiconductor packaging processes. As a key component, the clamping fixture's main function is to stably hold the workpiece during the welding process, ensuring the accuracy and reliability of the welding.

[0003] With the rapid development of microelectronics technology, the requirements for packaging density and precision are increasing, and the variety of products is diversifying. Traditional pressure plate fixtures are gradually revealing many shortcomings. These fixtures are often unable to meet the diverse packaging needs of today due to design limitations.

[0004] Traditional pressure plate designs typically employ fixed and uniform dimensions and structures, offering poor adaptability to workpieces of varying sizes, shapes, or materials. In actual production environments, the diversity of product specifications often necessitates multiple sets of pressure plates of different specifications to meet production demands. Frequent pressure plate changes not only increase production preparation time and operational complexity but may also lead to reduced production efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pressure plate fixture for a packaging and bonding machine, which aims to solve the problem of insufficient compatibility of pressure plate fixtures in existing packaging and bonding equipment.

[0006] To achieve the above objectives, the embodiments of this utility model are implemented through the following technical solution: a pressure plate fixture for a bonding machine, comprising: a pressure plate body, a pressure block, and an elastic pressure plate; the pressure plate body is provided with a first window penetrating through the pressure plate body, and a plurality of positioning frames are provided on both sides of the first window; the pressure block includes a pressure block body and two pressure block ears, the two pressure block ears being symmetrically arranged at both ends of the pressure block body; the pressure block body corresponds to the position of the first window; the pressure block ears are adapted to the positioning frames; a product bonding window penetrating through the pressure block body is provided on the pressure block body; a second window penetrating through the elastic pressure plate is provided, the second window corresponding to the position of the first window; and a movable piece corresponding to the position of the positioning frames is provided on the elastic pressure plate.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: A first window is set on the main body of the pressure plate, and several positioning frames are set on both sides of the first window. Through the modular and universal design of the first window, the needs of various products can be met by changing the pressure blocks of different sizes and quantities. This allows small-sized tube shell products to install more pressure blocks to increase production capacity, and it is also suitable for large-sized tube shell products without length limitations, improving the compatibility of the pressure plate fixture and reducing the time and cost of frequently changing the pressure plate. Furthermore, the movable piece of the elastic pressure plate can adaptively adjust according to the actual thickness of the tube shell, ensuring that the elastic pressure plate can not only press stably, but also automatically adjust according to the product and the height of the pressure block, reducing the damage to the tube shell caused by the pressure block and improving the welding quality.

[0008] Furthermore, a positioning pin is provided on the main body of the pressure plate, and a positioning hole corresponding to the positioning pin is provided on the elastic pressure plate.

[0009] Furthermore, several bolt holes are evenly spaced on opposite sides of the pressure plate body.

[0010] Furthermore, a plurality of magnets are provided inside the pressure plate body, the magnets are located between the bolt holes and the first window, and the plurality of magnets are evenly distributed at intervals, and the elastic pressure plate is magnetically connected to the magnets.

[0011] Furthermore, the elastic pressure plate is provided with a positioning hole, which is adapted to the positioning pin, and the elastic pressure plate is attracted to the magnet by the positioning pin and the magnet.

[0012] Furthermore, the main body of the pressure plate is made of stainless steel.

[0013] Furthermore, the thickness of the main body of the pressure plate is 7 mm to 10 mm.

[0014] Furthermore, the elastic pressure plate is made of high-speed steel.

[0027] Please see Figures 1 to 5This utility model provides a pressure plate fixture for a bonding machine, including a pressure plate body 10, pressure blocks 20, and elastic pressure sheets 30. A first window 11 penetrating the pressure plate body 10 is provided on its upper surface. The size of the first window 11 depends on the product design size required for packaging; its width should meet the maximum width value of the product design, and its length adopts an integrated large window design. This allows products of different lengths to flexibly adapt to the positioning frame 16, enabling smaller tube shell products to accommodate more pressure blocks 20 to increase production capacity, while also being suitable for larger tube shell products without length limitations. This improves the compatibility of the pressure plate fixture and reduces the time and cost of frequently changing the pressure plate fixture. The first window 11 has two sides... Several positioning frames 16 are provided for convenient placement of the pressure block 20, enabling quick and accurate positioning and installation of the pressure block 20, thus improving production efficiency. Several bolt holes 14 are evenly spaced on both sides of the pressure plate body 10, penetrating the pressure plate body 10. The pressure plate body 10 is fixed to the bonding rail with screws 13. Several magnets 12 are provided inside the pressure plate body 10, located between the bolt holes and the first window, and evenly spaced. The elastic pressure plate 30 is magnetically connected to the magnets 12. Positioning pins 17 are provided on the pressure plate body 10, and the elastic pressure plate 30 is provided with positions corresponding to the positioning pins 17. The positioning hole 32, the elastic pressure plate 30 is attracted to the pressure plate body 10 by the positioning pin 17 and the magnet 12, and the disassembly and assembly can be completed without the use of additional tools, which is convenient for disassembly and installation. Compared with the bolt fixing method, it is not easy to wear, reduces labor time and cost, and reduces the maintenance and replacement cost of the fixture. The pressure plate body 10 is made of stainless steel, and its outer frame shape is adjusted according to the equipment track requirements. The thickness is 7 mm to 10 mm. The thickness should not be too thin. A certain thickness is required so that the screw can be embedded in the pressure plate, which is aesthetically pleasing and flat, and does not affect the function of the welding head. It should not be too thick, as excessive thickness will affect the bonding of the welding head, and ensure that the components of the welding head do not touch the pressure plate body 10; the pressure block 20 includes a pressure block body, Two pressure block ears 21 are provided. The pressure block body corresponds to the first window 11. The two pressure block ears 21 are symmetrically arranged at opposite ends of the pressure block body. The pressure block ears 21 are adapted to the positioning frame 16. The pressure block ears 21 are fitted into the positioning frame 16 so that the position of the pressure block 20 can be accurately aligned with the product. The number of pressure blocks 20 can be set as needed for different products to improve production efficiency. The size of the pressure block 20 can be changed according to product needs. A product bonding window 23 is opened on the pressure block body, which penetrates the pressure block body. The size of the bonding window 23 needs to be customized according to the allowable gap when the welding head and the wedge are pressed down. The minimum safe distance between the bonding window 23 and the cavity edge of the deep cavity product is 500um.The elastic pressure plate 30 is provided with a second window 31 penetrating through it, the second window 31 corresponding to the position of the first window 11. The elastic pressure plate 30 is provided with a movable piece 33 corresponding to the position of the positioning frame 16. The movable piece 33 is used to compensate for bonding product quality problems caused by tube shell tolerances. During equipment operation, when the product is pushed from the bottom of the pressure block 20 to the product bonding window 23, the tube shell of the product will be squeezed by the pressure block 20. When the tube shell is thick, the tube shell will drive the pressure block 20 to rise, and the elastic pressure plate 30 will be appropriately lifted by the pressure block 20, reducing damage to the tube shell from being pressed by the pressure block 20 and improving welding quality. When the tube shell is thin, the elastic pressure plate 30 can press the pressure block 20, preventing the product from shaking and becoming unstable during welding, leading to abnormal welding quality. Simultaneously, the independent movable piece 33 can prevent the lifting of a single pressure block 20 from affecting the tightness of other pressure blocks 20. The elastic pressure plate 30 is made of high-speed steel.
