[0025] Example

[0026] A multifunctional chip welding device comprises a welding platform and a suction device 7. The welding platform is used to place a product to be welded. The suction device 7 is used to suck the multifunctional chip and place the multifunctional chip at the welding position of the product to be welded. The welding platform comprises a base 1 and a storage plate 6. Support devices 5 are distributed at four corners of the bottom surface of the storage plate 6. The tops of the four support devices 5 form an assembly cavity 13 adapted to the storage plate 6. A weighing sensor 12 is provided between the storage plate 6 and the bottom surface of the assembly cavity 13. The lower part of the support device 5 is movably connected to the base 1. A driving motor 4 for driving the supporting device 5 to move up and down is provided on the base 1. The driving motor 4 has a built-in braking function. The driving motor 4 and the weighing sensor 12 are electrically connected to a controller (not shown in the figure). After the working end of the suction device 7 contacts the top surface of the welding platform, the controller controls each support device 5 according to the pressure value detected by each weighing sensor 12 to adjust the height of the storage plate 6 and make the top surface of the storage plate 6 parallel to the plane where the working end of the suction device 7 is located.

[0027] In this embodiment, Figure 1As shown, the welding platform is used to place the product to be welded, ensuring the stability and accuracy of the product during the welding process. The main function of the suction device 7 is to suck the multifunctional chip from the storage position and accurately place it at the designated welding position of the product to be welded. This automated process greatly improves the welding efficiency and reduces human errors. The base 1 provides a stable support base for the equipment, and the placement plate 6 directly carries the product to be welded. Support devices 5 are installed at the four corners of the bottom surface of the placement plate 6. These devices not only support the placement plate 6, but also ensure that the top surface of the placement plate 6 is parallel to the plane where the working end of the suction device 7 is located through its height adjustment function. This design ensures the position accuracy of the chip during welding. The weighing sensor 12 is distributed between the placement plate 6 and the bottom surface of the assembly cavity 13, and is used to detect the weight change on the placement plate 6 in real time. When the suction device 7 contacts the placement plate 6, the sensor can sense the pressure change, thereby providing data to the controller for height adjustment. The driving motor 4 is connected to the lower part of the supporting device 5, and is used to drive the supporting device 5 to move up and down, so as to adjust the height of the storage plate 6. The built-in braking function of the driving motor 4 ensures the stability of the storage plate 6 after it is adjusted into place. The controller receives data from the weighing sensor 12, and controls the driving motor 4 according to these data to adjust the height of each supporting device 5, so that the height of the storage plate 6 can be accurately adjusted to ensure that its top surface is parallel to the plane where the working end of the suction device 7 is located. This multifunctional chip welding equipment realizes an efficient and accurate chip welding process through its advanced welding platform design and intelligent control system, which not only improves production efficiency, but also reduces the difficulty of operation and the rate of human error.

[0028] Furthermore, the supporting device 5 includes a supporting rod 501 and an adjusting rod 502. Four supporting rods 501 surround the assembly cavity 13. The bottom surface of the supporting rod 501 and the top of the adjusting rod 502 are integrally formed. The lower end of the adjusting rod 502 is movably connected to the base 1. A plurality of teeth 503 are provided on the outer wall of the adjusting rod 502 along its length direction. The driving motor 4 is fixed on the base 1, and the output shaft of the driving motor 4 is provided to mesh with the adjusting rod 502.

[0029] Specifically, Figure 1 and Figure 2 As shown, the support rod 501 is the main part of the support device 5. The four support rods 501 together form an assembly cavity 13 for supporting the storage plate 6. The design of the support rod 501 needs to be strong enough to bear the weight of the storage plate 6 and the products to be welded thereon. The adjustment rod 502 is a part of the support rod 501 and is integrally formed with the bottom surface of the support rod 501. The lower end of the adjustment rod 502 is movably connected to the base 1, which means that the adjustment rod 502 can move freely on the base 1, thereby adjusting the height of the storage plate 6.

[0030] A plurality of teeth 503 are provided on the outer wall of the adjusting rod 502 along its length direction, so that the adjusting rod 502 becomes teeth 503 , and these teeth 503 are used to mesh with the gear 3 on the output shaft of the driving motor 4 , so as to realize precise control of the position of the adjusting rod 502 . The driving motor 4 is fixed on the base 1, and a gear 3 matching the teeth 503 on the adjusting rod 502 is provided on its output shaft. When the driving motor 4 is started, the gear 3 on its output shaft will mesh with the teeth 503 on the adjusting rod 502, thereby driving the adjusting rod 502 to move up and down. Since each supporting device 5 is equipped with a driving motor 4, the height of each supporting rod 501 can be adjusted independently. When the working end of the suction device 7 contacts the top surface of the placement plate 6, if the plane where the working end is located is flush with the top surface of the placement plate 6, then the weight data obtained by the four weighing sensors 12 are the same; if the weight data obtained by a certain weighing sensor is easier than the data of the other weighing sensors 12, it means that the plane where the working end is located is not parallel to the top surface of the placement plate 6. At this time, it is necessary to adjust the height of the corresponding adjusting rod 502, thereby changing the height of the four corners of the placement plate 6 to ensure the parallelism of the top surface of the placement plate 6 and the plane where the working end of the suction device 7 is located.

[0031] Through this design, not only can the height of the storage plate 6 be accurately adjusted, but also each support rod 501 can be ensured to provide stable support, which helps to maintain the stability of the product to be welded during the welding process, thereby improving the welding quality. In addition, since the drive motor 4 has a built-in braking function, when the adjustment is completed, the drive motor 4 can quickly stop and lock the position of the adjustment rod 502, thereby preventing the storage plate 6 from moving during the welding process. The design of this support device 5 provides a flexible and stable height adjustment function for the multifunctional chip welding equipment, ensuring the accuracy and efficiency of the welding process.

[0032] Furthermore, the support rod 501 is L-shaped, and four L-shaped support rods 501 form a rectangular assembly cavity 13 .

[0033] Specifically, the design of the L-shaped support rod 501 provides two mutually perpendicular parts, usually one is a vertical part, which is used to be integrally formed with the adjustment rod 502 and connected to the base 1; the other is a horizontal part, which is used to support the bottom surface of the storage plate 6. This structure can ensure that the support rod 501 has sufficient stability when bearing weight. Because the support rods 501 are L-shaped, they can be arranged more compactly, thereby making more efficient use of space, which is particularly important when designing compact welding equipment, and can ensure the control of the overall size of the equipment. The design of the L-shaped support rods 501 generally makes the assembly process simpler because their shape and connection method are more intuitive. In addition, because the support rods 501 are L-shaped, the height of the storage plate 6 can be easily adjusted by moving the adjustment rod 502. When the four L-shaped support rods 501 form a rectangular assembly cavity 13, they can ensure that the placement plate 6 is evenly and stably supported, which is crucial for maintaining the stability and precision of the products to be welded. The rectangular assembly cavity 13 makes it easier to align and position the placement plate 6 when placed, which is very important for ensuring the accuracy and consistency of welding. The design of the L-shaped support rods 501 and the rectangular assembly cavity 13 provides a stable and efficient support structure for this multifunctional chip welding equipment, ensuring the stability and precision of the products to be welded during the welding process.

[0034] Furthermore, the base 1 is provided with a sliding cavity 2 for allowing the adjusting rod 502 to be inserted. Figure 1 and Figure 3 As shown, the sliding cavity 2 provided on the base 1 for allowing the adjustment rod 502 to be inserted provides a stable and precise support adjustment mechanism for the multifunctional chip welding device, enhancing the stability, adaptability and maintainability of the device. These features together improve the overall performance of the device and the user experience.

[0035] Furthermore, the weighing sensor 12 is a sensor chip made based on the principle of varistor.

[0036] Furthermore, the suction device 7 is a vacuum suction device 7, the lower end of the suction device 7 is a working end, and the suction device 7 is connected to a vacuum pump 10 through a pipeline.

[0037] Furthermore, the suction device 7 includes a suction end 11, a clamping end 8, and an exhaust channel 9. The suction end 11 is located at the lower end of the suction device 7, the clamping end 8 is arranged back to back with the suction end 11, and the exhaust channel 9 runs through the suction end 11 and the clamping end 8 and is connected to the vacuum pump 10.

[0038] Furthermore, the suction end 11 is a working end for sucking the multifunctional chip, and the clamping end 8 is used to transfer the sucked multifunctional chip to the welding position.

[0039] Specifically, Figure 1 As shown, the working principle is: the vacuum suction device 7 uses the negative pressure generated by the vacuum pump 10 to suck and clamp the chip. When the vacuum pump 10 is started, negative pressure is formed in the exhaust channel 9 connected by the pipeline, so that adsorption force is generated between the suction end 11 and the chip, thereby firmly sucking the chip. The vacuum suction method has the advantages of strong suction force, simple operation, strong adaptability, etc. It can adapt to chips of different sizes and shapes, and can work stably in various environments, thereby improving the efficiency and quality of chip welding.

[0040] The suction end 11 is located at the lower end of the suction device 7 and is the part that directly contacts the chip. Its cross section is rectangular. As mentioned above, this design provides a larger contact area and stability, ensuring that the chip can be firmly sucked.

[0041] The clamping end 8 is arranged opposite to the suction end 11, and is used to transfer the chip to the welding position after sucking it. The design of the clamping end 8 can be adjusted according to specific needs to ensure the stability and safety of the chip during the transfer process. The exhaust channel 9 runs through the suction end 11 and the clamping end 8, and is connected to the vacuum pump 10. Its function is to transfer the negative pressure generated by the vacuum pump 10 to the suction end 11, thereby generating an adsorption force. The design of the exhaust channel 9 needs to ensure smooth airflow to improve the suction and clamping effect. When the vacuum pump 10 is started, a negative pressure is formed at the suction end 11 through the exhaust channel 9, and an adsorption force is generated between the suction end 11 and the chip, thereby firmly sucking the chip. After sucking the chip, the clamping end 8 clamps the chip and transfers it to the welding position. In this process, the exhaust channel 9 continues to provide negative pressure to ensure that the chip is always firmly clamped. After reaching the welding position, the chip can be released and prepared for welding by controlling the switch of the vacuum pump 10 or adjusting the negative pressure. The vacuum suction device 7 provides the multifunctional chip welding device with efficient, accurate and reliable chip suction and transfer functions. This design not only improves welding efficiency and quality, but also reduces operation difficulty and human error rate.

[0042] Further, the cross section of the suction end 11 is rectangular. Specifically, the rectangular design provides a larger contact area, so that the suction device 7 can grasp the chip more stably when sucking the chip. This stability reduces the risk of the chip falling off during movement or transportation, improves the reliability of operation, and the rectangular suction end 11 can adapt to chips of different sizes and shapes. By adjusting the working parameters of the suction device 7, such as suction force and position, the rectangular suction end 11 can flexibly grab chips of different specifications, thereby improving the versatility and adaptability of the device. The rectangular suction end 11 is easier to achieve alignment with the target position when placing the chip. Since the rectangle has clear boundaries and symmetry, this enables the suction device 7 to more accurately align the target when placing the chip in the welding position, reducing the possibility of positional deviation. The rectangular suction end 11 is relatively simple to manufacture and can be manufactured using standard processing technology and materials. In addition, due to the simple and clear shape, it is also more convenient and quick to maintain and replace the suction end 11. The design of the cross section of the rectangular suction end 11 helps to improve the stability, adaptability, alignment accuracy and convenience of manufacturing and maintenance of the suction device 7. Together, these advantages enhance the performance and efficiency of the multifunctional die bonding equipment, making the die bonding process more efficient, accurate and reliable.

[0043] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
