[0018] In order to make the above-mentioned purposes, features and advantages of the utility model more apparent, obvious and easy to understand, the specific implementation manners of the utility model will be described in detail below in combination with the drawings. In the following description, a lot of specific details are set forth in order to give a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the following disclosed specific embodiments.

[0019] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. Where, when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements can also be present. As used herein the terms "vertical", "horizontal", "left", "right" and similar terms are used for explanation purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0021] As shown in the Figs. 1-2 The utility model provides a kind of air intake filter device of chip cleaning equipment, including air intake pipe box 10, air intake isolation cover 20, air intake pipe 11 is provided in the air intake pipe box 10, air intake pipe 11 is used to supply air for the blowing device of chip cleaning equipment, the air intake isolation cover 20 is connected with the air intake pipe box 10, and one end of air intake pipe 11 is communicated to the inside of the air intake isolation cover 20, air intake isolation cover 20 provides isolation effect for the filter screen of air intake end and external environment, filter screen 21 is further provided in the air intake isolation cover 20, filter screen 21 is horizontally arranged, and the filter surface of filter screen is arranged upwards, and distance is kept between the top wall of air intake isolation cover 20, to enable air to enter by the upper portion of filter screen, the lower end of filter screen 21 is connected with air guide hose 22, and is communicated with the air intake pipe in air intake pipe box 10 by air guide hose 22, air guide hose 22 is made of flexible material, for example, plastic, rubber etc., flexible hose 22 can conduct filter screen with air intake pipe 11;Air inlet 25 is provided on the wall of air intake isolation cover 20, and the height of air inlet 25 is lower than the height of filter screen 21, so that the air that air inlet 25 enters into the inside of air intake isolation cover 20 must be moved upwards to be able to detour to the upper portion of filter screen 21, so that it is forced to flow one to move upwards, to realize the effect of filtering part of foreign matter, particle in air, especially large particle in air cannot reach filter screen 21, so that not only improve the filtering efficiency, but also effectively prolong the service life of filter screen.

[0022] The air inlet 25 is arranged on the side wall of the air intake isolation cover 20, and is close to the bottom of the air intake isolation cover 20. By using side air intake mode, the floating matter on the ground can be avoided from being brought into the air intake isolation cover 20 by air flow.

[0023] The bottom of the air inlet isolation cover 20 is a sealing plate, so that the gas can only enter through the air inlet 25 on the side wall. The sealing plate isolates the air below the air inlet isolation cover 20, avoiding the air below the air inlet isolation cover 20 directly entering the inside of the air inlet isolation cover. At the same time, the sealing plate also makes the impurities in the upward airflow fall and collect on the sealing plate. Since the airflow on the upper surface of the sealing plate is basically not flowing, the impurities and particles will not be carried up again once they fall onto the sealing plate.

[0024] The filter screen 21 is installed on a support frame 23, and the support frame 23 is sealingly connected with the air guide hose 22. The support frame 23 plays a supporting and fixing role. Through the sealing connection of the support frame 23 and the air guide hose 22, the sealing effect is also effectively promoted.

[0025] The support frame 23 is provided with a gas sensor 24, and the gas sensor 24 is located in the air guide hose 22. The gas sensor 24 can detect the particulate matter content in the air filtered by the filter screen. Once the particulate matter content exceeds the set value, it is judged that the filter screen needs to be replaced.

[0026] The power supply device 13 of the gas sensor 24 is located in the air inlet pipe box 10 and is installed in a detachable manner.

[0027] The air inlet pipe box 10 is provided with a quick interface for replacing the filter screen 21, and the quick interface is located on the partition plate between the air inlet pipe box 10 and the air inlet isolation cover 20. The quick interface is beneficial to the replacement of the filter screen.

[0028] The air inlet pipe box 10 is provided with an openable sealing door 12 on the side, so as to facilitate the replacement of the filter screen 21. After the sealing door is opened, the inside of the air inlet pipe box 10 can be checked, and the filter screen 21 can be replaced.

[0029] The air inlet filtering device of the chip cleaning equipment provided by the utility model can filter and process the impurities and particles in the air, avoid the impurities and particles in the air entering the chip cleaning equipment, so that the purity of the chip surface can be maintained when the chip is subjected to heating, blowing and drying treatment, and the chip surface is not polluted. The filtering device in the application is designed through a path structure, so that the air must enter the side of the air inlet isolation cover 20, then is forced to flow upwards to the upper side of the filter screen 21, and then enters the air inlet pipe through the filter screen 21. During this period, since the air flows upwards, part of the impurities is naturally separated and collected by the bottom plate, so that the filtering effect is improved, and the filtered impurities are prevented from staying in other positions outside the air inlet isolation cover 20 in the factory building environment.

[0030] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered as within the scope of the present disclosure.

[0031] The above-described embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, but it shall not be understood as the limitation of the scope of the present application patent. It should be pointed out that, for the ordinary skilled in the art, under the premise of not departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent shall be subject to the appended claims.
