Description

Technical Field

[0001] This utility model relates to the field of chip coating technology, and in particular to a spray head structure for chip coating. Background Technology

[0002] In the field of chip manufacturing and packaging, coating process is a key step in ensuring chip performance stability, anti-interference ability and lifespan. Its core is to use a spray head to accurately and evenly cover the chip surface or specific areas with functional spray liquids such as insulating coating, protective adhesive, and thermal conductive paste to form a thin film layer that meets the process requirements. As chips rapidly develop towards high integration, miniaturization and thinness, more stringent requirements are placed on the precision, consistency and production efficiency of coating process. As the core execution component of coating equipment, the performance of the spray head directly determines the coating quality and the smoothness of the production process.

[0003] During long-term use, tiny particulate impurities inevitably exist in the spraying liquid. These impurities tend to accumulate on the surface of the filter components inside the spray head, causing the filter components to become clogged. Traditional spray head filter components are mostly designed to be built-in and fixed. Once clogged, the entire spray head must be removed from the coating equipment before the filter components can be cleaned or replaced. This is not only cumbersome and time-consuming, but it can also force the coating production line to stop, seriously affecting the continuity of production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a chip coating spray head structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a chip coating spray head structure, comprising a spray head body, a filter assembly disposed within the spray head body, an inlet pipe fixedly connected to the upper end of the spray head body, a branch pipe fixedly connected to one side of the inlet pipe, a ball rotatably connected to one end of the branch pipe, a rubber tube fixedly connected to one side of the ball, a sealing head fixedly connected to one end of the rubber tube, a bolt threadedly connected to the sealing head, and a valve at the lower end of the inlet pipe.

[0006] As a further description of the above technical solution: a drain pipe is fixedly connected to one side of the spray head body, and a valve is provided on the drain pipe.

[0007] As a further description of the above technical solution: a fixed column is fixedly connected to one side of the liquid inlet pipe, a fixed frame is fixedly connected to one end of the fixed column, a limit rod is rotatably connected to the fixed frame, a torsion spring is fixedly connected to one side of the limit rod, and one end of the torsion spring is fixedly connected to the fixed frame.

[0008] As a further description of the above technical solution: the fixed frame is provided with a groove, and the limiting rod is provided in the groove.

[0009] As a further description of the above technical solution: the sphere is provided with a through hole, and the rubber tube is connected to the through hole of the sphere.

[0010] As a further description of the above technical solution: the lower end of the rubber tube passes through the sealing head, and the bolt passes through the sealing head.

[0011] As a further description of the above technical solution: the branch pipe passes through the liquid inlet pipe, the liquid inlet pipe passes through the spray head body, and the liquid outlet pipe passes through the spray head body.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, when the filter component inside the spray head body is blocked by tiny particles in the spray liquid, there is no need to disassemble the equipment. The spray liquid in the inlet pipe is used to backwash the filter component, remove the blockage, and the flushed impurities are discharged through the drain pipe. This significantly reduces downtime caused by equipment disassembly and maintenance, ensures the continuity of production, and improves overall production efficiency.

[0014] 2. In this utility model, after cleaning, the rubber tube and the ball are rotated by turning the sealing head, so that the through hole on the ball is misaligned with the hole of the branch pipe, preventing the spraying liquid from being discharged from the inlet pipe. Then, the rubber tube is stored in the fixed frame by the cooperation of the limiting rod and the torsion spring. The operation is simple and effectively avoids the problem of spraying liquid leakage, ensuring the cleanliness of the working environment and the safety of the equipment.

[0024] Example 1:

[0025] like Figures 1 to 4 As shown, a chip coating spray head structure includes a spray head body 1, a filter assembly 2 inside the spray head body 1, an inlet pipe 3 fixedly connected to the upper end of the spray head body 1, a branch pipe 4 fixedly connected to one side of the inlet pipe 3, a ball 5 rotatably connected to one end of the branch pipe 4, a rubber tube 6 fixedly connected to one side of the ball 5, a sealing head 7 fixedly connected to one end of the rubber tube 6, a bolt 8 threadedly connected to the sealing head 7, and a valve 9 provided at the lower end of the inlet pipe 3.

[0026] In addition, in this embodiment, the spraying liquid enters the spray head body 1 through the inlet pipe 3, is filtered by the filter assembly 2, and is sprayed out from the spray head body 1, thereby forming the basic structure of spraying. The filter assembly 2 removes impurities from the spraying liquid.

[0027] Specifically, a drain pipe 10 is fixedly connected to one side of the spray head body 1, and a valve 11 is provided on the drain pipe 10.

[0028] In this embodiment, by opening valve 2 11, the liquid inside the spray head body 1 can be discharged through the drain pipe 10, which provides a liquid discharge channel for discharging impurities generated during rinsing.

[0029] Specifically, a fixing post 12 is fixedly connected to one side of the liquid inlet pipe 3, a fixing frame 13 is fixedly connected to one end of the fixing post 12, a limit rod 14 is rotatably connected to the fixing frame 13, a torsion spring 15 is fixedly connected to one side of the limit rod 14, and one end of the torsion spring 15 is fixedly connected to the fixing frame 13.

[0030] As a preferred implementation, the rubber tube 6 can be placed into the fixed frame 13 by moving the limiting rod 14. After releasing, the torsion spring 15 drives the limiting rod 14 to reset and fix the rubber tube 6, thereby realizing the storage and fixation of the rubber tube 6 and preventing it from shaking randomly.

[0031] Specifically, the fixed frame 13 is provided with a groove, and the limiting rod 14 is provided in the groove.

[0032] In this embodiment, the limiting rod 14 is embedded in the groove under the action of the torsion spring 15, which restricts the rubber tube 6 from leaving the fixing frame 13 and enhances the stability of the rubber tube 6 after it is stored.

[0033] Specifically, the sphere 5 is provided with a through hole, and the rubber tube 6 is connected to the through hole of the sphere 5.

[0034] With this configuration, when the ball 5 rotates to the point where the through hole connects with the branch pipe 4, the spraying liquid can enter the rubber tube 6 through the branch pipe 4 and the through hole of the ball 5, which is used to control the delivery of the spraying liquid to the rubber tube 6.

[0035] Specifically, the lower end of the rubber tube 6 passes through the sealing head 7, and the bolt 8 passes through the sealing head 7.

[0036] The bolt 8 is screwed into the threaded hole at the bottom of the spray head body 1 to fix the sealing head 7. The rubber tube 6 introduces the spraying liquid into the spray head body 1 for fixing the sealing head 7 and conveying the flushing liquid.

[0037] Specifically, the branch pipe 4 passes through the liquid inlet pipe 3, the liquid inlet pipe 3 passes through the spray head body 1, and the drain pipe 10 passes through the spray head body 1.

[0038] In this embodiment, the inlet pipe 3 delivers the spraying liquid into the spray head body 1, the branch pipe 4 connects the inlet pipe 3 with the rubber tube 6, and the drain pipe 10 discharges the liquid from the spray head body 1, ensuring the connection between each pipe and the spray head body 1, and realizing the delivery and discharge of the liquid.

[0039] Working principle: When in use, first connect the liquid inlet pipe 3 to the spraying equipment, then the spraying equipment delivers the spraying liquid into the liquid inlet pipe 3, and then the spraying head body 1 sprays the chip surface.

[0040] When the filter component 2 inside the spray head body 1 is blocked by tiny particles in the spray liquid during the chip spraying process, the plugging head 7 is fitted onto the bottom of the spray head body 1, and then the bolt 8 is tightened. When one end of the bolt 8 is threaded into the threaded hole at the lower end of the spray head body 1, the plugging head 7 is fixed. Then, valve 1 9 is closed and valve 2 11 is opened. At this time, the spray liquid in the inlet pipe 3 is transported into the branch pipe 4 and then into the rubber tube 6 through the through hole on the ball 5. Subsequently, it enters the spray head body 1 through the plugging head 7 to flush the filter component 2. The spray liquid in the inlet pipe 3 impacts the surface of the filter component 2 to remove the blockage. There is no need to disassemble the equipment, which significantly reduces downtime. The flushed impurities are discharged into the spray head body 1 through the drain pipe 10.

[0041] After cleaning, close the drain pipe 10 and open valve 9. Then, twist the bolt 8 in the opposite direction to disengage it from the spray head body 1 and disengage the sealing head 7 from one end of the spray head body 1. Then, pull the sealing head 7 upward. The sealing head 7 drives the rubber tube 6 to move. The rubber tube 6 drives the ball 5 to rotate in the branch pipe 4. After the ball 5 rotates 180 degrees, the through hole on the ball 5 is misaligned with the hole in the branch pipe 4, thereby preventing the spray liquid from being discharged from the inlet pipe 3. Then, pull the limiting rod 14 upward to rotate it on the fixed frame 13 and twist the torsion spring 15. After the limiting rod 14 rises to a certain position, place the rubber tube 6 in the fixed frame 13 and release the limiting rod 14. The torsion spring 15 twists in the opposite direction to reset the limiting rod 14 in the groove on the fixed frame 13, thereby completing the storage of the rubber tube 6.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
