Description

Technical Field

[0001] This utility model relates to the field of semiconductor packaging technology, specifically to a substrate pre-pressing fixture. Background Technology

[0002] Wire bonding is a common technique in the semiconductor, materials science, and precision manufacturing industries. It has wide applications in electronics, machinery, and aerospace, such as in the manufacture of semiconductor devices, precision mechanical parts, and aerospace structural components. In semiconductor packaging, substrate bonding is a process within wire bonding. Sufficient substrate adsorption is a crucial step in this process; insufficient adsorption leads to weak bonding, affecting product performance and lifespan.

[0003] In existing technologies, increasing pre-pressure is commonly used to enhance the adsorption force of the liner. Specifically, before the liner is bonded, a certain pressure is applied to create pre-stress in the liner, thereby strengthening its adsorption force. Additionally, the adsorption capacity of the liner can be improved by optimizing the design of the fixture. For example, adding special structures such as protrusions or grooves to the fixture increases the contact area between the liner and the fixture, thus improving the adsorption force.

[0004] However, the above-mentioned methods of increasing pre-pressure still have shortcomings: the existing pre-pressure methods are mainly achieved manually, which is complicated to operate, inefficient, and difficult to precisely control the magnitude and uniformity of pre-pressure, which can easily lead to uneven bonding of the liner and affect the quality of the product; in addition, the existing fixtures have special structures. Although these special structures can increase the contact area of ​​the liner pre-pressure position to improve the adsorption force, the current special structure manufacturing process is complicated and costly. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a liner pre-compression fixture. This liner pre-compression fixture can quickly and accurately position the liner and has the advantages of uniform pre-pressure application and simple structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pre-compression fixture for lining plates is provided, including:

[0008] The pre-compression fixture for the liner plate disclosed in this embodiment includes:

[0009] A pressure plate, with a positioning tray below it, the positioning tray being used to place the bonding backing plate;

[0010] A vacuum suction cup is located below the positioning tray and is used to adsorb the liner on the positioning tray.

[0011] A lifting cylinder is located below the vacuum suction cup. The lifting cylinder drives the vacuum suction cup plate to rise or fall and moves the positioning tray closer to or away from the pressure plate. When the positioning tray is close to the pressure plate, the pressure plate pre-presses the liner on the positioning tray. After the liner pre-pressing is completed, the positioning tray moves away from the pressure plate.

[0012] Since the positioning tray is located below the pressure plate, the vacuum suction cup is located below the positioning tray, and the lifting cylinder is located below the vacuum suction cup, the lifting cylinder can sequentially drive the vacuum suction cup and the positioning tray to lift upwards, so that the positioning tray is pressed against the pressure plate. At this time, the liner on the positioning tray is both attracted and positioned by the vacuum suction cup and pressed against the pressure plate, which can make the liner be pressed stably and evenly, improving the pre-pressing uniformity of the liner.

[0013] The lifting cylinder drives the vacuum suction cup to press the positioning tray against the pressure plate. On the one hand, it can automatically drive the liner to pre-press without manual control of the pressing process, avoiding the problem of inaccurate pressing. On the other hand, the pre-pressing process of the liner not only uses the suction force of the vacuum suction cup to apply suction and pre-pressing to the liner, but also combines the pressing force of the pressure plate to pre-press the liner, ensuring that the liner can be pre-pressed quickly and evenly. This avoids the problem of uneven pressing caused by the vacuum suction cup or pressure plate alone. At the same time, it can also eliminate the need for special structural settings, simplify the entire fixture, and reduce costs.

[0014] In some embodiments, the positioning tray is placed on a transport assembly, which drives the positioning tray to move above the vacuum suction cup. After the positioning tray is loaded with a liner to be bonded, the transport assembly drives the positioning tray to directly above the vacuum suction cup. After the liner bonding is completed, the transport assembly drives the positioning tray to the unloading station.

[0015] This transport assembly is used to transport the positioning tray, eliminating the need to move components such as vacuum suction cups and pressure plates. The positioning tray is simply transported via the assembly, avoiding any impact on positioning accuracy and pre-pressing effect caused by moving the vacuum suction cups and pressure plates. Furthermore, the positioning tray can move quickly between vacuum suction cups simply by moving above them, facilitating automatic loading and unloading of liner plates.

[0016] In some embodiments, the transport assembly includes a rotary plunger and a linear guide post.

[0017] The rotary plunger is used to control the working state of the linear guide post, thereby limiting the position of the positioning tray and preventing mistaken insertion.

[0018] The linear guide posts are located on both sides of the vacuum suction cup. The positioning tray is detachably mounted on the two linear guide posts. The rotating plunger drives the guide posts to rotate and moves the positioning tray along the linear guide posts.

[0019] Two linear guide pillars allow the positioning pallet to move along them, simplifying the loading and unloading process. Since the positioning pallet is detachably mounted on the guide pillars, different pallets can be replaced according to the liner size. The mounted positioning pallet can be quickly lifted by a lifting cylinder using a vacuum suction cup. Furthermore, the pallet's transfer via the guide pillars reduces contact with the liner during transport, minimizing the impact of liner contamination on product quality and improving liner bonding yield. A commercially available rotary plunger effectively drives the guide pillars, thus moving the positioning pallet mounted on them.

[0020] Furthermore, sliders are provided on both sides of one side of the positioning tray. The positioning tray is engaged with the guide post by the sliders. Therefore, when pre-pressing different liners, the positioning tray needs to be replaced. At this time, the original positioning tray is taken off the guide post, and the positioning tray of the correct size is engaged with the guide post by the slider on the positioning tray. The slider can connect the positioning tray to the guide post and can also lift the lifting cylinder onto the pressure plate by the vacuum suction cup.

[0021] In some embodiments, the positioning tray has a plurality of positioning windows for positioning the liner.

[0022] The positioning window is configured to fit the liner, thus providing good stability to the liner.

[0023] In some embodiments, the pressure plate has a pressing window on the side facing the positioning tray that corresponds to the positioning window. The configuration of the pressing window is adapted to the configuration of the liner. The edge of the liner is pressed by the edge of the pressing window, and a sealing ring is fitted into the inner edge of each positioning window.

[0024] The pressure plate's function is to press the liner on the positioning tray into place. To better press the liner, corresponding pressing windows are also provided on the pressure plate, mirroring the positioning windows. To better protect the liner's surface, these pressing windows prevent scratches. The pressing windows use their edges to press against the edges of the liner, thus achieving a more effective pressing action. A sealing ring also ensures the positioning windows stably press the liner into place, while simultaneously preventing damage to the liner.

[0025] In some embodiments, the vacuum suction cup includes a stacked upper vacuum plate and a lower vacuum plate, the upper vacuum plate adsorbing the positioning tray.

[0026] The lower vacuum plate has a plurality of first vacuum holes, and the upper vacuum plate has a plurality of second vacuum holes, wherein the diameter of the first vacuum holes is larger than the diameter of the second vacuum holes.

[0027] The vacuum suction cup is configured with an upper vacuum plate and a lower vacuum plate, which allows the suction and discharge holes of the vacuum suction cup to have different diameters. The diameter of the first vacuum hole is larger than that of the second vacuum hole, which results in a lower airflow pressure in the first vacuum hole, which can better generate negative pressure and improve the vacuum suction effect of the second vacuum hole.

[0028] In some embodiments, the vacuum upper plate is further provided with a plurality of protrusions that can be embedded in the positioning window, and the second vacuum hole is formed on the protrusions.

[0029] The protrusion can penetrate into the positioning window to adsorb the liner inside the positioning window, and the protrusion can get closer to the liner on the positioning window, thus achieving a better vacuum adsorption effect.

[0030] In some embodiments, the top of the lifting cylinder is provided with a platform, and the lifting cylinder is connected to the vacuum suction cup through the platform.

[0031] The lifting cylinder can make good contact with the vacuum suction cup through this platform.

[0032] In some embodiments, a vacuum pressure gauge is connected between the vacuum suction cup and the positioning tray to detect the negative pressure state of the vacuum suction cup adsorbing the positioning tray.

[0033] This vacuum negative pressure gauge can monitor the effect of vacuum adsorption and better monitor the effect of vacuum suction cup adsorption on positioning trays.

[0034] In some embodiments, the positioning tray has pull tabs on its sides.

[0035] The positioning tray can be quickly and easily removed by pulling the lugs, allowing for easy replacement.

[0036] The beneficial effects of this utility model on the pre-compression fixture for lining plates are as follows:

[0037] This utility model's pre-pressing fixture for liners uses a lifting cylinder to drive a vacuum suction cup to press a positioning tray against a pressure plate. On one hand, it automatically drives the liner for pre-pressing, eliminating the need for manual control and preventing inaccurate pressing. On the other hand, the pre-pressing process combines the suction force of the vacuum suction cup with the pressing force of the pressure plate, ensuring rapid and uniform pre-pressing of the liner. This avoids uneven pressing caused by relying solely on the vacuum suction cup or pressure plate. Furthermore, it eliminates the need for special structural features, simplifying the entire fixture and reducing costs. Attached Figure Description

[0049] Example 1

[0050] The pre-compression fixture for the liner plate disclosed in this embodiment, such as Figures 1-6 As shown, it includes:

[0051] Pressure plate 1, with a positioning tray 2 below the pressure plate 1, the positioning tray 2 being used to place the bonding backing plate;

[0052] Vacuum suction cup 3, which is located below the positioning tray 2, is used to adsorb the liner on the positioning tray 2;

[0053] A lifting cylinder 6 is located below the vacuum suction cup 3. The lifting cylinder 6 drives the vacuum suction cup 3 plate to rise or fall and moves the positioning tray 2 closer to or away from the pressure plate 1. When the positioning tray 2 is close to the pressure plate 1, the pressure plate 1 pre-presses the liner on the positioning tray 2. After the liner pre-pressing is completed, the positioning tray 2 moves away from the pressure plate 1.

[0054] Since the positioning tray 2 is located below the pressure plate 1, the vacuum suction cup 3 is located below the positioning tray 2, and the lifting cylinder 6 is located below the vacuum suction cup 3, the lifting cylinder 6 can sequentially drive the vacuum suction cup 3 and the positioning tray 2 to lift upwards, so that the positioning tray 2 is pressed against the pressure plate 1. At this time, the liner on the positioning tray 2 is attracted and positioned by the vacuum suction cup 3 on the one hand, and pressed against the pressure plate 1 on the other hand, so that the liner is pressed stably and evenly, improving the pre-pressing uniformity of the liner.

[0055] The lifting cylinder 6 drives the vacuum suction cup 3 to press the positioning tray 2 against the pressure plate 1. On the one hand, it can automatically drive the liner to pre-press without manual control of the pressing process, avoiding the problem of inaccurate pressing. On the other hand, the pre-pressing process of the liner not only uses the suction force of the vacuum suction cup 3 to apply suction and pre-pressing to the liner, but also combines the pressing force of the pressure plate 1 to pre-press the liner, ensuring that the liner can be pre-pressed quickly and evenly. This avoids the problem of uneven pressing caused by only the vacuum suction cup 3 or the pressure plate 1. At the same time, it can also eliminate the need for special structural settings, simplify the entire fixture, and reduce costs.

[0056] More specifically, pressure plate 1 is used to press the substrate to be bonded. Positioning tray 2 is placed below pressure plate 1 to hold the substrate to be bonded. Vacuum suction cup 3 is located below positioning tray 2 to adsorb the substrate on positioning tray 2. Lifting cylinder 6 is located below vacuum suction cup 3 and drives vacuum suction cup 3 to rise or fall, so that positioning tray 2 moves closer to or away from pressure plate 1. That is, the substrate to be bonded is placed on positioning tray 2. Driven by lifting cylinder 6, vacuum suction cup 3 rises, and lifting cylinder 6 drives vacuum suction cup 3 and positioning tray 2 to lift upward, so that positioning tray 2 is pressed against pressure plate 1. At this time, the substrate is adsorbed and positioned by vacuum suction cup 3 and pressed by pressure plate 1, realizing stable and uniform pressing of the substrate. After pre-pressing is completed, lifting cylinder 6 drives positioning tray 2 away from pressure plate 1, completing the pre-pressing process of the substrate.

[0057] This enables an automated, uniform, and efficient pre-pressing process for the liner, improving production efficiency and product quality.

[0058] In this embodiment, the positioning tray 2 is placed on the transport component, and the transport component drives the positioning tray 2 to move above the vacuum suction cup 3. After the positioning tray 2 is loaded with the liner to be bonded, the transport component drives the positioning tray 2 to directly above the vacuum suction cup 3. After the liner bonding is completed, the transport component drives the positioning tray 2 to the unloading station.

[0059] This transport assembly is used to transport the positioning tray 2, eliminating the need to move components such as the vacuum suction cup 3 and the pressure plate 1. Only the positioning tray 2 needs to be transported via the assembly, avoiding any impact on positioning accuracy and pre-pressing effect caused by moving the vacuum suction cup 3 and the pressure plate 1. Furthermore, the positioning tray 2 can move quickly between the vacuum suction cups 3 simply by moving above them, facilitating automatic feeding and unloading of the liner plates.

[0060] More specifically, the transport component is responsible for moving the positioning tray 2 above the vacuum suction cup 3 to achieve automatic loading and unloading of the liner.

[0061] In this embodiment, the transport assembly includes a rotary plunger 7 and a linear guide post 8.

[0062] The rotary plunger 7 is used to control the working state of the linear guide post 8, thereby limiting the position of the positioning tray 2 and preventing mistaken insertion.

[0063] The two linear guide posts 8 are located on both sides of the vacuum suction cup 3. The positioning tray 2 is detachably mounted on the two linear guide posts 8. The rotating plunger 7 drives the guide posts to rotate and moves the positioning tray 2 along the linear guide posts 8.

[0064] Two linear guide posts 8 allow the positioning tray 2 to move along them, simplifying the loading and unloading process. Since the positioning tray 2 is detachably mounted on the linear guide posts 8, different positioning trays 2 can be replaced according to the liner size. The mounted positioning tray 2 can be quickly lifted by the lifting cylinder 6 using the vacuum suction cup 3. The rotary plunger 7, readily available commercially, effectively drives the guide posts to rotate, thus moving the positioning tray 2 mounted on them.

[0065] Furthermore, sliders 14 are provided on both sides of one side of the positioning tray 2. The positioning tray 2 is engaged with the guide post by the sliders 14. Therefore, when different liner plates are pre-pressed, the positioning tray 2 needs to be replaced. At this time, the original positioning tray 2 is taken off the guide post, and the positioning tray 2 of the same size is engaged with the guide post by the sliders 14 on the positioning tray 2. The sliders 14 can connect the positioning tray 2 to the guide post and can also lift the lifting cylinder 6 onto the pressure plate 1 by the vacuum suction cup 3.

[0066] More specifically, the rotating plunger 7 controls the working state of the linear guide posts 8, thus defining and preventing the positioning tray 2 from being mistakenly positioned. Two linear guide posts 8 are located on either side of the vacuum suction cup 3, and the positioning tray 2 is detachably mounted on them. In use, the positioning tray 2 is engaged with the linear guide posts 8 via the slider 14, facilitating quick replacement and fixation. The rotating plunger drives the linear guide posts 8 to rotate, moving the positioning tray 2 along them. During use, the corresponding positioning tray 2 is replaced according to different liner sizes and engaged with the linear guide posts 8 via the slider 14. This simplifies the loading and unloading routes and improves efficiency. The detachable positioning tray 2 facilitates replacement according to liner sizes.

[0067] The rotating plunger 7 drives the guide column to rotate, thereby moving the positioning tray 2, which is easy to operate.

[0068] This liner pre-pressing fixture achieves automatic liner loading and unloading through the movement of guide pillars. Simultaneously, the structure of the rotating plunger 7 and linear guide pillar 8 enables precise control and rapid replacement of the positioning tray 2. This not only improves the efficiency and uniformity of pre-pressing but also reduces costs and simplifies the operation process. This fixture allows for rapid and uniform pre-pressing of liners, improving production efficiency and product quality.

[0069] In this embodiment, the positioning tray 2 has a plurality of positioning windows 9 for positioning the liner. The configuration of the positioning windows 9 is adapted to the liner, thus enabling better stability of the liner.

[0070] In this embodiment, the pressure plate 1 has a pressing window 11 corresponding to the positioning window 9 on the side facing the positioning tray 2. The configuration of the pressing window 11 is adapted to the configuration of the liner. The edge of the liner is pressed by the edge of the pressing window 11, and a sealing ring 10 is fitted into the inner edge of each positioning window 9.

[0071] The function of the pressure plate 1 is to press the liner on the positioning tray 2. To better press the liner on the positioning tray 2, a pressing window 11 corresponding to the positioning window 9 is also provided on the pressure plate 1. To better protect the surface of the liner, the pressing plate 1 has a pressing window 11 to avoid scratching the surface of the liner. The pressing window 11 uses its own edge to press against the edge of the liner, thus achieving a better pressing effect. The sealing ring 10 can also stably press the liner and prevent the liner from being damaged.

[0072] The sealing ring 10 is used to enhance the adsorption force of the liner, ensure the stability of the liner during the vacuum adsorption process, and protect the liner from damage.

[0073] The liner is placed on the positioning window 9 of the positioning tray 2, and the edge of the liner is contacted by the sealing ring 10 of the pressing window 11.

[0074] The vacuum system is activated, and the liner is firmly attached to the positioning window 9 by the sealed environment formed by the sealing ring 10.

[0075] During the pre-pressing process, the sealing ring 10 not only provides stable adsorption force, but also presses the liner to prevent the liner from shifting or deforming under pressure.

[0076] After pre-pressing is completed, the vacuum system is turned off and the liner is removed. Thanks to the protection of the sealing ring 10, the liner will not be damaged during the adsorption process. The liner pre-pressing fixture not only improves the efficiency and quality of liner pre-pressing but also reduces damage to the liner during production through the protection of the sealing ring 10, thereby improving product yield and economic benefits.

[0077] In this embodiment, the pressure plate 1 has a pressing window 11 on the side facing the positioning tray 2, which corresponds to the positioning window 9. The configuration of the pressing window 11 is adapted to the configuration of the liner, and the edge of the liner is pressed by the edge of the pressing window 11.

[0078] The function of the pressure plate 1 is to press the liner on the positioning tray 2. In order to better press the liner on the positioning tray 2, a pressing window 11 corresponding to the positioning window 9 is also opened on the pressure plate 1. In order to better protect the surface of the liner, the pressing plate 1 has a pressing window 11 to avoid scratching the surface of the liner. The pressing window 11 uses its own edge to press the edge of the liner, thereby achieving a better pressing effect.

[0079] In use, the liner plate 1 is placed on the positioning window 9 of the positioning tray 2 and fixed by vacuum adsorption. Utilizing the edge pair of the pressing window 11, damage to the liner plate during production is reduced through the protective function of the pressing window 11, thereby improving product yield and economic efficiency. This makes the fixture more suitable for liner plates of different sizes and shapes, enhancing the fixture's applicability and flexibility.

[0080] In this embodiment, the vacuum suction cup 3 includes a vacuum upper plate 31 and a vacuum lower plate 32 stacked together. The vacuum upper plate 31 adsorbs the positioning tray 2.

[0081] The lower vacuum plate 32 has a plurality of first vacuum holes, and the upper vacuum plate 31 has a plurality of second vacuum holes, wherein the diameter of the first vacuum holes is larger than the diameter of the second vacuum holes.

[0082] The vacuum suction cup 3 is configured with a vacuum upper plate 31 and a vacuum lower plate 32, which makes it possible for the suction hole and suction hole of the vacuum suction cup 3 to have different diameters. The diameter of the first vacuum hole is larger than that of the second vacuum hole, so that the airflow pressure of the first vacuum hole, which serves as the suction hole, is low, which can better generate negative pressure and improve the vacuum suction effect of the second vacuum hole.

[0083] In this embodiment, the vacuum upper plate 31 is further provided with a plurality of protrusions, which can be embedded in the positioning window 9, and the second vacuum hole is opened on the protrusions.

[0084] The protrusion can penetrate into the positioning window 9 to adsorb the liner inside the positioning window 9, and the protrusion can get closer to the liner on the positioning window 9, thus achieving a better vacuum adsorption effect.

[0085] In this embodiment, the top of the lifting cylinder 6 is provided with a platform 12, and the lifting cylinder 6 is connected to the vacuum suction cup 3 through the platform 12.

[0086] The lifting cylinder 6 can make good contact with the vacuum suction cup 3 through the platform 12.

[0087] In this embodiment, a vacuum pressure gauge is connected between the vacuum suction cup 3 and the positioning tray 2 to detect the negative pressure state of the vacuum suction cup 3 adsorbing the positioning tray 2.

[0088] This vacuum pressure gauge can monitor the effect of vacuum adsorption, and can better monitor the effect of vacuum suction cup 3 adsorbing positioning tray 2. Therefore, the vacuum pressure gauge can provide accurate negative pressure monitoring for the liner pre-pressing fixture, ensuring that vacuum suction cup 3 effectively adsorbs positioning tray 2, thereby improving the efficiency and quality of the entire pre-pressing process.

[0089] In this embodiment, the positioning tray 2 is provided with a pull lug 13 on its side.

[0090] The positioning tray 2 can be quickly and easily removed by pulling the lug 13, thereby replacing the positioning tray 2.

[0091] The aforementioned fixture uses guide pillars to transfer the tray, reducing contact with the liner during transfer and minimizing the impact of liner contamination on product quality, thereby improving the liner bonding yield. This fixture can be combined and adjusted by changing the pressure plate 1 and product tray to meet different needs, simplifying the manufacturing process and reducing costs. After the positioning tray 2 is transferred, the fixture uses a rotating plunger 7 to position and prevent mistaken insertion of the product tray, effectively positioning the product tray assembly during production to ensure proper assembly between the product tray and the vacuum plate, improving the liner adsorption capacity.

[0092] The pre-compression method of the present invention is achieved by pressure plate 1 and cylinder, which can achieve uniform pre-compression of the liner, making the liner more tightly adsorbed, improving the adsorption capacity of the liner, and avoiding the complexity of manual pre-compression operation, thus improving work efficiency. At the same time, by adjusting the air pressure, the magnitude and uniformity of the pre-compression force can be precisely controlled, ensuring the uniformity of the liner bonding, thereby improving the firmness of the liner during bonding.

[0093] Example 2

[0094] To further illustrate the method of using the fixture in Embodiment 1, the following usage steps are disclosed:

[0095] The process of enhancing the adsorption capacity of the liner by adding a pre-compression function:

[0096] The product to be bonded (backing plate) is placed into the corresponding positioning tray 2. Then, the positioning tray 2 with the backing plate is placed on the guide post via the slider 14 on the positioning tray 2. The positioning tray 2 is then transferred to the vacuum upper plate 31 of the vacuum suction cup 3 via the guide post. The rotating plunger 7 is used for limiting and preventing mistake.

[0097] Press the start button for the electric drive (electronic switch controlling the lifting cylinder 6) to start the lifting cylinder 6.

[0098] The lifting cylinder 6 drives the vacuum upper and lower plates and the positioning tray 2 to be lifted. During the lifting process, the pressure plate 1 pre-presses the liner on the positioning tray 2, thereby achieving uniform pre-pressing of the liner, making the liner and the vacuum upper plate 31 more closely contacted, improving the adsorption capacity of the liner, thereby improving the stability and reliability of the vacuum bonding fixture's adsorption of the liner, and improving the quality of the bonded product.

[0099] Press the start button for the electric drive (controlling the vacuum solenoid valve) to vacuum-adsorb the pre-compressed liner. In addition, the vacuum pressure gauge readings can be used to visually observe the liner adsorption process.

[0100] After bonding is complete, press the stop button of the electric drive (controlling the vacuum solenoid valve) to release the vacuum adsorption. Press the stop button of the electric drive (controlling the cylinder electronic switch) to make the lifting cylinder 6 drive the upper and lower vacuum plates and the positioning tray 2 to descend. After the descent is complete, smoothly remove the positioning tray 2. After removing the tray, place the processed liner in the designated position.

[0101] The aforementioned fixture, used for pre-pressing liners, achieves positioning and error-proofing functions through guide posts and rotating plungers 7; and by changing pressure plates 1 and positioning trays 2, it enables the bonding of liners of different types and sizes. During production, electronic control avoids the complexity of manual operation, greatly improving work efficiency. Simultaneously, adjusting air pressure allows for precise control of the magnitude and uniformity of the pre-pressure, ensuring uniform liner bonding and improving product quality.
