Abstract
Description
Technical field:
[0001] The utility model relates to the field of tooling, in particular to a fixing tooling for an acid discharge pump. Background technology:
[0002] Silicon wafers are often used to make integrated circuits and solar cells. During the manufacturing process, organic matter, metal impurities, oxides and other contaminants may exist on the surface of the silicon wafer, which will affect the quality and performance of the silicon wafer surface. Therefore, hydrofluoric acid is often used to clean silicon wafer samples.
[0003] The cleaning method is to manually use a handheld acid pump to pump the acid from the acid barrel into the acid tank for use. The acid barrel is a medium-to-large acid barrel with a cylindrical structure and two openings on the top. The handheld acid pump has high flexibility and can be applied to a variety of manual equipment and a relatively narrow on-site space, so it is used more frequently. However, it relies on personnel to hold the acid pump for a long time until the acid is drained and then take it out. During the process, due to the vibration of the acid pump body, the placement of the acid pump at the mouth of the acid barrel, and possible misoperation by personnel, it is very easy to cause acid dripping or leakage, causing harm to personnel.

Specific implementation method:
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] like Figure 1-Figure 4As shown, an acid discharge pump fixing tool comprises a circular collecting tank 1 and an acid pump limiting tank 2. A circular ring 3 of equal diameter is arranged below the circular collecting tank 1. A connecting rod 4 is fixed between the bottom of the circular collecting tank 1 and the circular ring 3. The inner diameter of the circular ring 3 matches the outer diameter of the acid barrel 10 and can be slightly larger. The circular ring 3 is sleeved on the acid barrel 10, and the circular collecting tank 1 is placed on the top of the acid barrel 10, so that the circular collecting tank 1 can be stably placed on the top of the acid barrel 10.
[0021] The acid pump limiting groove 2 is arranged in the circular collecting groove 1, and the bottom of the acid pump limiting groove 2 is fixed to the groove bottom of the circular collecting groove 1 by a supporting rod 5, the bottom of the acid pump limiting groove 2 is hollowed out, the groove bottom of the circular collecting groove 1 is provided with a through hole 6 corresponding to the opening of the acid barrel 10, the bottom of the acid pump limiting groove 2 corresponds to the through hole 6, the inner groove size of the acid pump limiting groove 2 is also designed to match the acid pump 11, although the bottom of the acid pump limiting groove 2 is hollowed out, there are still edges protruding in the horizontal direction, the acid pump 11 can be supported, the acid pump 11 can be embedded in the acid pump limiting groove 2 from above, the inlet of the acid pump 11 is connected to the hose 12, the inlet hose 12 passes through the bottom of the acid pump limiting groove 2 and the through hole 6 and extends into the acid barrel 10 to extract the acid;
[0022] A first opening 7 is provided on the side wall of the acid pump limiting groove 2, and a second opening 8 is provided on the side wall of the circular collecting groove 1 corresponding to the first opening 7. The outlet of the acid pump 11 is connected to a hose 12, and the hose 12 of the outlet passes through the first opening 7 and the second opening 8 and is placed outside the circular collecting groove 1, and can be extended into the acid groove to discharge the acid extracted from the acid barrel 10 into the acid groove for use.
[0023] The bottom of the circular collecting tank 1 is conical. When the acid pump 11 vibrates or the hose 12 is opened to enter and exit the acid barrel 10, acid liquid may leak into the circular collecting tank 1 to avoid leakage and potential safety hazards. The bottom of the circular collecting tank 1 is conical, so that the leaked acid is concentrated at the bottom of the tank, or flows back to the acid barrel through the through hole 6 along the inclined surface of the bottom of the tank.
[0024] The bottom of the circular collecting tank 1 is provided with two through holes 6 matching the number of openings of the two acid barrels 10. The bottom of the circular collecting tank 1 between the two through holes 6 is arched upward. When acid liquid leaks from the bottom of the circular collecting tank 1, it can flow downward along the arched bottom of the circular collecting tank 1 and flow back to the opening of the acid barrel 10 through the two through holes 6.
[0025] A conical outlet pipe 9 fixed to the bottom of the circular collecting tank 1 is provided below the through hole 6. The conical outlet pipe 9 is convenient for aligning with the opening of the acid barrel 10 so that the through hole 6 accurately corresponds to the opening of the acid barrel 10. The inlet hose 12 can also prevent the acid from leaking between the bottom of the circular collecting tank 1 and the top of the acid barrel 10 when entering and exiting the opening of the acid barrel 10.
[0026] Working principle: When the utility model is in use, the ring 3 is put on the acid barrel 10, the circular collecting tank 1 is placed on the top of the acid barrel 10, the through hole 6 is aligned with the opening of the acid barrel 10, and the acid pump 11 is embedded in the acid pump limiting groove 2. At the same time, the hose 12 of the acid pump 11 inlet passes through the bottom of the acid pump limiting groove 2 and the through hole 6 and extends into the acid barrel 10, and the hose 12 of the acid pump 11 outlet passes through the first opening 7 and the second opening 8 and is placed in the acid tank, and the acid in the acid barrel 10 is pumped out and discharged into the acid tank for use through the acid pump 11.
[0027] The circular ring 3 of the novel invention is sleeved on the acid barrel 10, and the circular collecting tank 1 can be placed on the top of the acid barrel 10. The acid pump limiting groove 2 in the circular collecting tank 1 can stably place the acid pump 11 above the acid barrel 10. The hose 12 at the inlet of the acid pump 11 is directly connected to the acid barrel 10, and the hose 12 at the outlet of the acid pump 11 is placed in the acid tank. The acid is pumped into the acid tank from the acid barrel for use, which replaces hand-held operation and avoids manual fatigue. At the same time, the acid pump limiting groove 2 is sleeved on the acid barrel 10 by the circular ring 3, which is convenient for moving and replacing the acid barrel 10 and flexible in use. The circular collecting tank 1 can collect acid liquid dripping or leaking from the acid pump 11, thereby reducing safety hazards.
