Description

Technical Field

[0001] This utility model relates to the field of chip processing technology, specifically to a vibration-assisted feeding device for chip mounting. Background Technology

[0002] In the electronics manufacturing industry, chip mounting is a crucial step, and the efficiency and precision of its loading technology directly impact the quality and cost of the entire production process. As electronic products trend towards miniaturization and high integration, higher demands are placed on chip mounting technology. Achieving efficient, accurate, and stable chip loading has become a critical issue that the electronics manufacturing industry urgently needs to address. Vibration loading technology utilizes the force generated by vibration to move chips on a tray, thereby arranging and transporting them. Its principle involves a vibration source generating vibrations of a specific frequency and amplitude, causing the tray to vibrate and the chips within it to move and flip. A vision-based grasping system then acquires image information of the chips through image acquisition equipment and uses image processing algorithms to identify the chip's position, orientation, and other features, guiding a robotic arm to accurately grasp the chips. When the two work together, vibration loading provides the visual grasping system with orderly arranged chips, while the visual grasping system precisely positions the vibrated chips.

[0003] However, most vibration-assisted feeding devices currently employ a one-piece molded structure. This structure makes the various components of the device tightly integrated, making disassembly difficult. When the trays wear out due to long-term use or need to be replaced according to different chip specifications, the operation becomes extremely cumbersome, requiring a significant amount of time and manpower, severely impacting production schedules. Moreover, if a component inside the device malfunctions, the limitations of the one-piece structure make it difficult for maintenance personnel to quickly locate and replace the faulty component, resulting in high maintenance costs, reduced overall device efficiency, and an inability to meet the flexible needs of diverse chip mounting and feeding. Utility Model Content

[0004] The purpose of this invention is to provide a vibration-assisted feeding device for chip mounting, so as to solve the problem mentioned in the background art that the existing chip vibration-assisted feeding device is an integrated structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A vibration-assisted feeding device for chip mounting includes a hollow vibration base for chip mounting and a flexible vibratory plate for vibration feeding that can be detached and replaced. Several voice coil motors are evenly spaced and arranged in a ring on the bottom edge of the hollow vibration base, and a base is installed at the bottom of the voice coil motor. The hollow vibrating base has a hollow area inside. Several sets of air inlets connected to the hollow area are opened at the center of the top surface of the hollow vibrating base. Fixing ports are symmetrically opened on both sides of the top surface of the hollow vibrating base. A negative pressure fan is installed on the inner wall of the hollow area. An air outlet is opened on the outer wall of the hollow vibrating base and connected to the air outlet of the negative pressure fan. The bottom surface of the flexible vibratory plate is equipped with plug-in posts that are the same number, size, and position as the fixed plug-in ports and are plugged in to fit together.

[0006] Preferably, the length of the insertion post and the depth of the fixed socket can effectively prevent the flexible vibratory feeder from loosening or shifting during the vibration feeding process, ensuring that the chip can vibrate and adjust its posture on a stable platform, thereby improving the stability and reliability of the feeding process.

[0007] Preferably, the number of voice coil motors is 3-6, which can provide sufficient and uniform vibration power to the hollow vibrating base. Different combinations of numbers can be flexibly selected according to the actual chip characteristics and feeding requirements, meeting diverse production scenarios and improving the effect and efficiency of vibration feeding.

[0008] Preferably, the base and the hollow vibration base have the same bottom area and are coaxially arranged to ensure the overall stability of the device's center of gravity.

[0009] Preferably, a servo lifting cylinder is installed at the bottom of the base, which can flexibly adjust the height of the device according to actual production needs. This adapts to different working environments and chip mounting requirements, improving the applicability and flexibility of the device.

[0010] Preferably, the top of the piston rod of the servo lifting cylinder is coaxially connected to the center of the bottom surface of the base.

[0011] Preferably, the bottom surface of the servo lifting cylinder is equipped with a fixing plate for fixing to the ground or workbench, which can stably fix the device to the ground or workbench. This prevents the device from moving due to vibration or external force during operation, providing a stable working environment for chip loading.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: In this chip mounting vibration-assisted feeding device, the hollow vibration base and the detachable and replaceable flexible vibration plate allow the device to flexibly replace the flexible vibration plate according to different chip mounting requirements, improving the applicability of the device; by installing several voice coil motors evenly spaced and arranged in a ring on the bottom edge of the hollow vibration base, the voice coil motors can provide stable and uniform vibration power to the hollow vibration base, thereby effectively assisting chip feeding; by installing a base at the bottom of the voice coil motors, the entire device can be stably placed on the work platform; by setting a hollow area inside the hollow vibration base, and opening several sets of air inlets connected to the hollow area at the center of the top surface of the hollow vibration base, external air can enter the hollow area through the air inlets; by opening an air outlet on the outer wall of the hollow vibration base connected to the air outlet of the negative pressure fan, the air in the hollow area can be smoothly discharged when the negative pressure fan is working, forming a negative pressure environment in the hollow area. Because several sets of air inlets connected to the hollow area are opened at the center of the top surface of the hollow vibrating base, the flexible vibrating plate will be adsorbed onto the hollow vibrating base under negative pressure, which enhances the connection stability between the flexible vibrating plate and the hollow vibrating base, prevents the flexible vibrating plate from shifting or loosening during vibration, and ensures the smooth progress of the vibration feeding process.

[0017] Vibration-assisted feeding devices for chip mounting, such as Figures 1-3As shown, the device includes a hollow vibrating base 10 for chip mounting and a removable and replaceable flexible vibrating plate 20 for vibratory feeding. Several voice coil motors 40 are evenly spaced and arranged in a ring around the bottom edge of the hollow vibrating base 10, and a base 30 is installed at the bottom of each voice coil motor 40. A hollow region 13 is provided inside the hollow vibrating base 10. Several sets of air inlets 11 communicating with the hollow region 13 are opened at the center of the top surface of the hollow vibrating base 10. Fixed insertion ports 12 are symmetrically opened on both sides of the top surface of the hollow vibrating base 10. A negative pressure fan 14 is installed on the inner wall of the hollow region 13, and an air outlet 15 connected to the air outlet of the negative pressure fan 14 is opened on the outer wall of the hollow vibrating base 10. The bottom surface of the flexible vibrating plate 20 is equipped with insertion posts 21 that are the same number, size, and position as the fixed insertion ports 12 and are plugged in. Through the hollow vibrating base 10 and the removable and replaceable flexible vibrating plate 20, the device... The device can flexibly replace the flexible vibratory feeder 20 according to different chip mounting requirements, improving the applicability of the device; by installing several voice coil motors 40 evenly spaced and arranged in a ring at the bottom edge of the hollow vibratory base 10, the voice coil motors 40 can provide stable and uniform vibration power to the hollow vibratory base 10, thereby effectively assisting the chip loading; by installing a base 30 at the bottom of the voice coil motors 40, the entire device can be stably placed on the work platform; by setting a hollow area 13 inside the hollow vibratory base 10, and opening several sets of air inlets 11 connected to the hollow area 13 at the center of the top surface of the hollow vibratory base 10, external air can enter the hollow area 13 through the air inlets 11; by opening an air outlet 15 on the outer wall of the hollow vibratory base 10 connected to the air outlet of the negative pressure fan 14, the air in the hollow area 13 can be smoothly discharged when the negative pressure fan 14 is working, forming a negative pressure environment in the hollow area 13. Because several sets of air inlets 11 connected to the hollow area 13 are opened at the center of the top surface of the hollow vibrating base 10, the flexible vibrating plate 20 will be adsorbed on the hollow vibrating base 10 under the action of negative pressure, which enhances the connection stability between the flexible vibrating plate 20 and the hollow vibrating base 10, prevents the flexible vibrating plate 20 from shifting or loosening during vibration, and ensures the smooth progress of the vibration feeding process.

[0018] It is worth noting that the length of the plug 21 and the depth of the fixed socket 12 allow the plug 21 to be fully inserted into the fixed socket 12, ensuring the tightness and stability of the connection between the flexible vibrating plate 20 and the hollow vibrating base 10, and preventing loosening during vibration.

[0019] The number of voice coil motors 40 is 3-6 sets, which enables the hollow vibration base 10 to obtain sufficient and uniform vibration power. Different numbers of voice coil motors 40 can be selected according to the actual chip mounting requirements to meet diverse vibration feeding requirements and improve the flexibility and practicality of the device.

[0020] Furthermore, the base 30 and the hollow vibration base 10 have the same bottom area and are coaxially arranged, which makes the overall center of gravity of the device stable, maintains balance during vibration, reduces shaking and displacement, and ensures the stability and reliability of the chip loading process.

[0021] Specifically, a servo lifting cylinder 50 is installed at the bottom of the base 30. The top of the piston rod 51 of the servo lifting cylinder 50 is coaxially connected to the center of the bottom surface of the base 30, so that the height of the hollow vibration base 10 can be adjusted by controlling the servo lifting cylinder 50, thereby adapting to different working scenarios and chip mounting requirements and improving the applicability of the device.

[0022] In addition, the bottom surface of the servo lifting cylinder 50 is equipped with a fixing plate 52 for fixing to the ground or workbench, so that the servo lifting cylinder 50 and the entire device can be stably fixed to the ground or workbench, preventing the device from moving during operation and ensuring the smooth progress of chip loading.

[0023] The working principle of the vibration-assisted feeding device for chip mounting: First, select a suitable flexible vibratory plate 20 according to the chip mounting requirements, align the bottom plug 21 with the fixing socket 12 on the top surface of the hollow vibratory base 10 and insert it, so that the flexible vibratory plate 20 is stably installed on the hollow vibratory base 10. Next, the negative pressure fan 14 on the inner wall of the hollow zone 13 is started. Air enters the hollow zone 13 through the air inlet 11 and is discharged through the air outlet 15 by the negative pressure fan 14, forming a negative pressure in the hollow zone 13 to further fix the flexible vibrating plate 20. Then, the voice coil motor 40 is turned on, and the vibration it generates is transmitted to the hollow vibrating base 10, which in turn drives the flexible vibrating disk 20 to vibrate, causing the chip placed on the flexible vibrating disk 20 to roll continuously until the chip faces upward. During this process, the chip's position and status are accurately identified in conjunction with a vision grasping system; If the height of the device needs to be adjusted, the servo lifting cylinder 50 at the bottom of the base 30 can be controlled to extend and retract the piston rod 51 to lift the base 30 and the entire device. The fixed plate 52 at the bottom of the device can be fixed to the ground or workbench to ensure the stability of the device during operation, thereby successfully completing the chip loading.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
