Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning a semiconductor copper wire bonding fixture, and in particular relates to a cleaning device for the fixture. Background Art

[0002] After using the semiconductor copper wire bonding fixture for a period of time, it will become dirty and the rubber will fall off, resulting in poor pressing of the bonding fixture. In mild cases, the gold ball or copper ball of the first bonding solder joint will be peeled off, and in severe cases, the first solder joint will not be able to be welded directly, which greatly affects the product quality and pass rate of the first solder joint in the bonding process.

[0003] At present, the traditional operation method in the industry is to stack the used bonding fixtures in a small plastic box, and then place the small plastic box in an ultrasonic container containing alcohol for ultrasonic cleaning. After cleaning, check whether the fixture is damaged under a high-power microscope. If it is damaged and exceeds the scrap standard, it will be scrapped. If the fixture is confirmed to be normal, it will be covered with rubber. The entire cleaning and inspection process is troublesome, inefficient, and there is a risk of damaging the fixture. The existing traditional bonding fixture cleaning method has the following defects: 1. The existing traditional cleaning method requires a large amount of alcohol, which increases the company's use cost; 2. In the existing traditional cleaning method, the cover plate and the cover plate and the heating block are prone to collision, resulting in fixture defects or reduced service life; 3. In the existing traditional cleaning method, the fixtures are stacked and there is no safety protection during the fixture cleaning process, which will result in the fixture being not cleaned properly, and there are safety risks for the staff during the cleaning process; 4. In the existing traditional cleaning method, the number of fixtures that can be cleaned each time is small, so the cleaning frequency increases, resulting in low work efficiency, increased labor costs and electricity costs. Utility Model Content

[0004] In view of the above-mentioned deficiencies existing in the prior art, the utility model provides a cleaning device for a clamp to solve the above-mentioned existing problems.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A fixture cleaning device comprises an ultrasonic cleaning machine, a fixture cleaning jig arranged in the ultrasonic cleaning machine, and a cleaning protective cover rotatably connected to the top of the ultrasonic cleaning machine, wherein the fixture cleaning jig comprises a side frame and a plurality of bottom brackets fixedly connected to the side frame, the plurality of bottom brackets are all fixedly connected with support blocks, and the support blocks are provided with a plurality of fixture placement grooves.

[0007] Furthermore, there are eight bottom brackets, which are correspondingly distributed in the side frames.

[0008] Furthermore, the fixture placement grooves are evenly distributed on the support block.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. The utility model can clean the fixture more cleanly, can clean more fixtures, can save alcohol consumption, greatly improve work efficiency, and reduce use cost and labor cost;

[0011] 2. When cleaning the fixture, the cover plate and the heating block are placed separately, which can avoid collision and wear of the fixture parts and greatly improve the service life of the fixture;

[0012] 3. The utility model is provided with a protective cover, which increases the safety factor during the cleaning process. BRIEF DESCRIPTION OF THE DRAWINGS
