Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic cleaning, in particular to an ultrasonic cleaning telescopic bracket. Background Art

[0002] With the development of semiconductors and chips, the ball implanting and dispensing jig is a special mold for ball implanting. After dispensing, there is residual flux on the dispensing needle on the mold, which needs to be cleaned. The usual cleaning method is to set up a basin-shaped bracket, put alcohol in the bracket, and then put the mold upside down on the bracket to immerse the needle in alcohol for cleaning. However, there are the following problems during cleaning: (1) The length of the bracket is fixed and cannot be adjusted according to the length of the mold, resulting in low adaptability; (2) The bracket is closed on all sides, and the liquid level of the alcohol cannot be observed, which makes it easy for the alcohol to be higher than the pinhole, causing the flux to enter the pinhole, affecting the rebound of the dispensing needle, and causing missed printing during dispensing. Utility Model Content

[0022] 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 in 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.

[0023] Example 1

[0024] See also Figure 1 and Figure 2An ultrasonic cleaning telescopic bracket includes a bracket A1 and a bracket B2 combined with the bracket A1. The bracket A1 and the bracket B2 are both made of hard plastic to reduce weight and have high hardness. The bracket A1 and the bracket B2 are both U-shaped. The end face of the bracket A1 is provided with a slot 3, and the end face of the bracket B2 is connected with a plug rod 4. The bracket A1 and the bracket B2 are plugged in through the cooperation of the plug rod 4 and the slot 3, and are fixed by screws after plugging. The bracket A1 is provided with a screw hole 6, and the bracket B2 is provided with a strip hole 7 that cooperates with the screw hole 6. Dispensing molds of different lengths can adjust the length of the bracket by loosening the screws and translating the position of the bracket B2, so as to adapt to molds of different lengths.

[0025] Furthermore, the outer wall and the inner wall of the bracket B2 are provided with liquid level scales 5. By observing the height of the cleaning liquid, the problem of setting the height of the cleaning liquid and the difficulty in monitoring it is effectively solved, and the glue is prevented from flowing back into the pinhole along with the cleaning liquid.

[0026] The opposite ends of the bracket A1 and the bracket B2 are connected with upwardly protruding limit blocks 8. The four limit blocks on the top of the bracket are used to limit the mold to prevent the mold from moving.

[0027] like Figure 2 As shown, it is a schematic diagram of the existing cleaning bracket and the dispensing mold, wherein a plurality of needles are provided at the bottom of the dispensing mold, and needle tubes are connected to the needles, and the needle tubes are fixed in the positioning frame. During cleaning, the cleaning liquid easily overflows the positioning frame and enters through the pinhole on the needle tube, affecting the rebound of the needle.

[0028] The working principle of this embodiment is:

[0029] Before use, measure the length of the dispensing mold, combine the A / B brackets, and insert the screws and nuts. When the length of the inner frame of the bracket is consistent with the length of the mold, tighten the screws to fix the combined bracket. The length of the bracket can be adjusted by loosening the positioning screws and translating the position of the bracket B for different lengths. When cleaning, place the dispensing mold 10 on the bracket. The four limit blocks 8 on the top of the bracket are used to fix the mold to prevent the mold from moving. Observe the scale on the bracket corresponding to the horizontal plane where the needle is located, and then place the bracket in the cleaning tank of the ultrasonic cleaning machine. Add the cleaning liquid to the corresponding scale height. The dispensing mold head is placed in the middle hollow part. A certain width is left around the outer frame of the bracket to carry the mold and fit the mold. The mold is in a horizontal position to ensure that the needle is immersed in the liquid surface at the same depth and will not rise to the pinhole of the needle tube, ensuring that the flux on the needle will not flow into the pinhole. After cleaning and taking it out, take out the dispensing mold and blow it dry. At this time, the bracket can be used as a mold storage bracket.

[0030] Example 2

[0031] Based on Example 1, the end surface of the bracket A1, the end surface of the bracket B2, and both sides of the bracket B2 are provided with through holes 9. Large through holes 9 are provided on the sides of the surrounding outer frame to increase the flow of the cleaning liquid and to facilitate observation of whether the needle is immersed in the liquid surface.
