Description

Technical Field

[0001] The present invention relates to the technical field of chip packaging, and particularly relates to an efficient dispensing auxiliary device for chip packaging. Background Art

[0002] The chip packaging dispenser is a key device in semiconductor manufacturing and assembly. Its main function is to accurately coat liquid materials such as glue and sealant on electronic components to achieve functions such as chip connection, filling and protection.

[0003] In order to improve the accuracy and efficiency of dispensing during chip packaging, many improvements have been made to the dispensing device during chip packaging in the prior art. For example, Chinese Patent CN116020705A discloses a dispenser for chip packaging, which includes a transmission box and a fixed frame fixed on the transmission box. A rotating tray is coaxially fixed on the central shaft, a dispensing head is fixed on the lifting frame, two extension plates are arranged below the lifting frame, a vertical elastic component is installed on the extension plates, a clamping component for limiting the chip is installed on the L-shaped sliding plate, and both sides of the intermediate gear are meshed with sliding racks slidably connected to the lifting frame; when the dispensing head in the invention moves down to perform the dispensing operation on the chip, the intermediate gear can drive the two sliding racks to slide, and the two extension plates approach each other. The trapezoidal pressing plate can perform horizontal and vertical limiting processing on the chip below the dispensing head, ensuring the stability of the dispensing process.

[0004] The above patent has obvious beneficial effects, but there are still the following deficiencies in actual operation:

[0005] 1. The dispenser uses two trapezoidal pressing plates to approach the chip from the side to achieve horizontal and vertical limiting of the chip. During the process of the trapezoidal pressing plate pressing the chip, relative sliding is likely to occur between the two, resulting in mechanical damage due to friction and affecting the quality of the finished product.

[0006] 2. The glue is a liquid with high viscosity. After the dispensing is completed, during the upward movement of the glue tube, a long trailing or filamentous structure is likely to form at the end, which will affect the current and subsequent chip packaging processes.

[0007] Based on this, the present invention designs an efficient dispensing auxiliary device for chip packaging to solve the above problems. Summary of the Invention

Specific embodiments

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] In the following description, "left", "right", "front", "rear", "upper", and "lower" mentioned are oriented in the perspective direction of the front view. The present invention will be further described below with reference to the embodiments.

[0031] Embodiment 1: In some embodiments, please refer to Figure 1 of the accompanying drawings of the specification. An efficient dispensing auxiliary device for chip packaging includes a base 1. A gantry 2 is arranged at the upper end of the base 1. A dispensing automatic cleaning mechanism 4 and a dispenser 9 are connected to the front end of the gantry 2. The lower end of the dispensing automatic cleaning mechanism 4 is connected to the dispenser 9. A belt conveyor 5 is arranged between the two bases 1. The two bases 1 are symmetrically distributed left and right along the belt conveyor 5. A chip placement table 6 is fixedly connected to the conveyor belt of the belt conveyor 5. The chip placement tables 6 are evenly distributed at equal intervals along the conveyor belt of the belt conveyor 5. On the front and rear sides of each chip placement table 6 at the end away from the belt conveyor 5, side limit blocks 7 are fixedly connected. A synchronous bidirectional clamping mechanism 3 is connected to the upper end of each base 1. The two synchronous bidirectional clamping mechanisms 3 are symmetrically distributed left and right along the belt conveyor 5. The synchronous bidirectional clamping mechanism 3 includes a horizontal clamping assembly 31 and a vertical clamping assembly 32. The horizontal clamping assembly 31 and the vertical clamping assembly 32 are connected to the upper end of the base 1. While the horizontal clamping assembly 31 clamps the chip 8 in the horizontal direction, it will drive the vertical clamping assembly 32 to clamp the chip 8 in the vertical direction.

[0032] In the present invention, at the feeding end of the belt conveyor 5, the chip 8 is placed on the chip placement table 6. The side limit blocks 7 will limit the chip 8 in the front and rear directions. The belt conveyor 5 conveys the chip placement table 6 towards the dispenser 9. When the chip 8 is transferred by the belt conveyor 5 to the lower part of the dispensing automatic cleaning mechanism 4, the horizontal clamping assembly 31 moves towards the direction close to the chip 8. While moving, the horizontal clamping assembly 31 will drive the vertical clamping assembly 32 to move to a position close to the chip 8 to fix the chip 8. The dispenser 9 starts dispensing. After the dispenser 9 finishes dispensing, the dispensing automatic cleaning mechanism 4 will automatically clean the gun head of the dispenser 9. The horizontal clamping assembly 31 resets, and at the same time drives the vertical clamping assembly 32 to reset, releasing the chip 8. The chip 8 is transferred by the belt conveyor 5 to its discharging end.

[0033] In the present invention, the side limit blocks 7 are fixed in the front-back direction of the chip 8, and the horizontal clamping assembly 31 and the vertical clamping assembly 32 are fixed in the left-right and up-down directions of the chip 8 respectively, ensuring the stability of dispensing. After the dispensing is completed, the dispensing automatic cleaning mechanism 4 will automatically clean the nozzle of the dispenser 9, removing the glue solution that is likely to adhere to the surface of the nozzle during the dispensing process, preventing waste glue from adhering to the workpiece to be processed, and ensuring the overall quality of the dispensed product.

[0034] Embodiment 2: In some embodiments, please refer to the Figure 3 of the attached drawings of the specification. The horizontal clamping assembly 31 includes a cylinder 311, a horizontal clamping slide rail 312, a horizontal support block 313 and a horizontal clamping block 314. The horizontal clamping slide rail 312 is fixedly connected to the upper end of the base 1. The horizontal support block 313 is slidably connected to the upper end of the horizontal clamping slide rail 312 in a limited manner. The cylinder 311 is fixedly connected to the upper end of the base 1. The horizontal support block 313 is fixedly connected to the output end of the cylinder 311 in the direction away from the chip 8. The horizontal clamping block 314 is fixedly connected to the end of the horizontal support block 313 away from the chip 8. When the chip 8 is moved to the lower side of the dispenser 9, the horizontal clamping block 314 clamps the side surface of the chip 8, and the surface of the horizontal clamping block 314 is provided with a silica gel coating.

[0035] Please refer to the Figure 3 of the attached drawings of the specification. The vertical clamping assembly 32 includes a vertical support block 321, a vertical limit ring 322, a vertical limit post 323, a limit sliding block 324 and a vertical clamping block 325. The vertical support block 321 is fixedly connected to the upper end of the base 1. The vertical limit ring 322 is fixedly connected to the upper end of the vertical support block 321. The upper end of the vertical limit post 323 is slidably connected to the vertical limit ring 322 in a limited manner. The lower end of the vertical limit post 323 is fixedly connected to the limit sliding block 324. A vertical limit groove 326 is formed on the horizontal support block 313. The limit sliding block 324 is slidably and limit-connected to the vertical limit groove 326. The upper end of the vertical clamping block 325 is fixedly connected to the upper end of the vertical limit post 323 through a connecting plate. When the chip 8 is moved to the lower side of the dispenser 9, the vertical clamping block 325 presses the chip 8 from the upper side of the chip 8 towards the chip placement table 6, and the surface of the vertical clamping block 325 is provided with a silica gel coating.

[0036] When the chip 8 is moved under the dispensing automatic cleaning mechanism 4, the cylinder 311 pushes the horizontal support block 313 to move horizontally towards the chip 8 under the limiting action of the horizontal clamping slide rail 312. The horizontal clamping block 314 clamps the chip 8 from the side. While the horizontal support block 313 moves horizontally, the horizontal support block 313 drives the limit sliding block 324 to move in a limited manner in the vertical limit groove 326. The limit sliding block 324 drives the vertical limit post 323 to move vertically towards the chip 8 under the limiting action of the vertical limit ring 322. The vertical clamping block 325 clamps the chip 8 from the upper side. After the dispenser 9 completes dispensing, the cylinder 311 controls the horizontal clamping block 314 and the vertical clamping block 325 to reset.

[0037] In the present invention, it is realized that only one drive can be used to clamp and fix the chip 8 synchronously in two directions, namely horizontally and vertically. The simple structure ensures the stability of the chip 8 during the dispensing process. At the same time, since the fixing method is direct clamping and pressing, there is no mechanical friction on the chip 8, which further improves the quality stability of the product. In addition, the silica gel coating on the surfaces of the horizontal clamping block 314 and the vertical clamping block 325 can improve the clamping force of the clamping block, and at the same time increase the buffer when pressing the chip 8, playing a protective role.
