Technical Field

[0001] This utility model belongs to the field of semiconductor processing technology, and in particular relates to an automatic dispensing device for semiconductor packaging. Background Technology

[0002] Semiconductor packaging dispensing equipment is a device used to perform dispensing operations during the semiconductor device packaging process. Dispensing is one of the key processes, and its accuracy and stability directly affect product quality. However, existing automated dispensing equipment for semiconductor packaging still has some problems.

[0003] For example, the utility model patent with publication number CN222447084U includes a workbench. The front and rear ends of the upper surface of the workbench are provided with first grooves. A slide rod is fixedly connected in the first groove at the front end of the upper surface of the workbench. A support block is provided inside the first groove. A first electric telescopic rod is fixedly connected at the center of the upper surface of the support block. In the actual use of the dispensing device, the dispensing head needs to be frequently replaced to adapt to different glue characteristics, such as viscosity, filler ratio and dispensing pattern accuracy requirements. However, the dispensing head of this utility model has a fixed structure, which is inconvenient to replace and affects work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic dispensing device for semiconductor packaging. By incorporating a locking box, during installation, pressing a button simultaneously moves two sliding rods downwards via a connecting block. This causes slider five to slide on the inner wall of slide groove two, which in turn moves slider four between two limiting plates, thus disengaging the two locking clips. The dispensing head is then inserted into the outer surface of the interface. Releasing the button causes the spring force to reset the locking clips, bringing them into contact with the inner wall of the slot, thus securing the dispensing head. Disassembly is similar; pressing the button disengages the locking clips from the slot. This locking and slot mechanism allows for quick disassembly of the dispensing head, facilitating replacement and solving the problem of existing automatic dispensing devices for semiconductor packaging having fixed dispensing heads, which are inconvenient to replace and affect work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an automatic dispensing device for semiconductor packaging, comprising an operating table and a dispensing bottle. An interface is fixedly connected to the bottom of the dispensing bottle, and a dispensing head is inserted into the outer surface of the interface. A slot is formed on the outer surface of the dispensing head. A locking box is fixedly connected to the outer surface of the dispensing bottle. Two latches are slidably connected inside the locking box, with the outer surfaces of the two latches contacting the inner wall of the slot. A slider four is fixedly connected to opposite sides of each of the two latches. A sliding groove two is formed at the bottom of the slider four, and a slider five is slidably connected to the inner wall of the sliding groove two. The inside of the locking box is close to the sliding groove five. Limiting plates are fixedly connected to the top and bottom of block four. One side of each limiting plate is slidably connected to the outer surface of block four. Sliding rods are fixedly connected to the front of each of the two blocks five.

An air pipe 132 is fixedly connected to the right side of the vacuum machine 131. The side of the air pipe 132 away from the vacuum machine 131 is fixedly connected to the right side of the vacuum adsorption platform 13. By setting up the vacuum adsorption platform 13, the encapsulated workpiece is placed on the top of the vacuum adsorption platform 13.

[0030] The top of the operating table 1 is provided with a slide groove 14. A lead screw 141 is rotatably connected to the inner wall of the slide groove 14. A slider 142 is slidably connected to the inner wall of the slide groove 14. The inside of the slider 142 is threadedly connected to the outer surface of the lead screw 141.

[0031] A specific application of this embodiment is as follows: During installation, pressing button 239 simultaneously moves the two sliding rods 236 downwards via connecting block 238. At this time, slider five 234 slides on the inner wall of sliding groove two 233, causing slider four 232 to slide between the two limiting plates 235, thereby causing the two locking buckles 231 to move away from each other. The dispensing head 22 is then inserted into the outer surface of interface 21. After releasing the button, the spring force of spring 237 causes the locking buckle 231 to reset, making it contact the inner wall of the slot 221, thus completing the fixation of the dispensing head 22. The same principle applies to disassembly; pressing button 239 disengages the locking buckle 231 from the slot 221. Then, the encapsulated workpiece is placed on top of the vacuum adsorption stage 13, and the vacuum machine 131 is started. A negative pressure is formed on top of the vacuum adsorption stage 13 through the air pipe 132 to fix the encapsulated workpiece and prevent displacement during the dispensing process. Then, motor two 123 is started. The screw 121 rotates on the inner wall of the slide rail 12, causing the slider 122 to slide on the inner wall of the slide rail 12. This causes the dispensing bottle 2 to move up and down via the dispensing frame 124, controlling the dispensing height. The motor 113 is started, driving the gear 114 to rotate, which causes the slider 112 to move along the rack 111, thus adjusting the left and right position of the dispensing bottle 2. While moving, the slider 112 slides on the outer surface of the limiting guide rail 115, which provides a stable motion trajectory for the slider 112. The motor 145 is started, driving the gear 144 to rotate, which in turn causes the screw 141 to rotate on the inner wall of the slide groove 14 via the gear 143. This causes the slider 142 to slide on the inner wall of the slide groove 14, which in turn causes the vacuum adsorption stage 13 to move back and forth, thereby indirectly adjusting the front and rear dispensing positions.
