Description

Technical Field

[0001] This utility model relates to the field of glue injection and maintenance technology for presses, and in particular to a glue injection mechanism. Background Technology

[0002] Clogging of the dispensing head is a common problem during molding and encapsulation processes. For example, low temperatures or insufficient pressure can cause poor fluid flow, leading to solidification and blockage inside the dispensing head. Alternatively, impurities in the fluid, such as unmelted filler or foreign matter, can directly clog the dispensing head's channels. Therefore, regular maintenance of the dispensing heads is necessary. However, the large number of dispensing heads makes unified maintenance difficult, and disassembly and cleaning after disassembly is inefficient.

[0003] Therefore, we propose a pressure bonding mechanism to solve the above problems. Utility Model Content

After the two arc-shaped blocks 6 are joined, the two clamping blocks 7 can slide circumferentially between the corresponding two arc-shaped blocks 6.

[0029] As a technical optimization of this utility model, the clamping block 7 can abut and fit with the sink 5, and the two clamping blocks 7 can clamp and position the dispensing head 4.

[0030] For the above example, those skilled in the art should know that when implementing the above technical solution, the number of arc-shaped blocks 6 and clamping blocks 7 is determined by the number of dispensing heads 4, and can be flexibly set according to the number of dispensing heads 4.

[0033] As a technical optimization of this utility model, the maintenance mechanism includes a water tank 10, with a plurality of water spray heads 11 evenly spaced at the bottom of the water tank 10, and two strip-shaped grooves 12 at the top of the water tank 10. Two strip-shaped blocks 9 can engage with the two strip-shaped grooves 12, and the plurality of water spray heads 11 can be aligned with the bottom of a plurality of glue injection heads 4. The plurality of water spray heads 11 are used to spray water, and the water flow impacts the bottom of the glue injection head 4 to achieve the effect of rinsing away impurities.

Maintenance involves placing several arc-shaped blocks 6 on either side of the dispensing heads 4, with two corresponding clamping blocks 7 aligned with the recesses 5 of the dispensing heads 4. This ensures the clamping blocks 7 and recesses 5 are properly engaged, positioning the dispensing heads 4. Then, the dispensing heads 4 are sequentially unscrewed, and two strip-shaped blocks 9 are engaged with two strip-shaped grooves 12, installing the dispensing heads 4 onto the water tank 10 for unified cleaning. Several water spray heads 11 are aligned with the bottom of the dispensing heads 4. The water spray heads 11 are then activated to impact and clean the dispensing heads 4. After cleaning, the top block 15 is positioned so that its air outlets 16 align with the top of the dispensing heads 4. High-pressure airflow is injected to blow out impurities from inside the dispensing heads 4 and to quickly dry their interior.

[0040] During the above operation, when the dispensing head 4 rotates, the two clamping blocks 7 rotate along with the dispensing head 4, and the two elastic telescopic rods 8 rise accordingly, without obstructing the disassembly of the dispensing head 4.
