Description

Technical Field

[0001] The present application relates to the technical field of semiconductor cleaning devices, and in particular to a suspended air blowing gun device. Background Art

[0002] In the field of semiconductor production, particles have a crucial impact on product quality. Semiconductor devices are extremely precise, and any tiny particles may cause device performance degradation or even failure. Therefore, the semiconductor production environment has extremely strict control over particles to ensure product quality and reliability.

[0003] However, despite strict control measures, the activities of people and the operation of equipment in the production environment will inevitably generate dust and other particles. Once these particles adhere to the surface of semiconductor products, they may have a serious impact on product performance. Due to the high precision of semiconductor products, traditional contact cleaning methods (such as wiping) may damage the product and are therefore not suitable for cleaning semiconductor products.

[0004] At present, the semiconductor industry generally uses nitrogen guns to remove particles from the surface of products. Nitrogen guns spray clean nitrogen and use the impact force of the gas to blow particles away from the surface of the product, achieving non-contact cleaning. This method protects the integrity of the product and avoids the damage that may be caused by contact cleaning.

[0005] However, existing nitrogen gun products have some problems in practical applications. First, the metal hook fixing method of the nitrogen gun is prone to wear and dust, which will affect the cleaning effect after long-term use. Secondly, once the gun body is worn and dusty, the entire nitrogen gun needs to be replaced, which not only increases production costs, but also increases the complexity of maintenance. In addition, when the nitrogen gun is used and put back on the hook for fixing, it is not easy to align the nitrogen gun, there is a risk of falling, and it also increases the possibility of generating dust and other particles. Utility Model Content

With the guidance of the magnetic suction force, the air blow gun can be placed in the correct position more accurately and easily. The magnetic suspension method prevents the gun body from contacting other structures, thereby eliminating unnecessary friction between the air blow gun and other structures, reducing dust and other particles generated by friction, helping to keep the working environment clean and reducing the possibility of secondary pollution.

The first magnetic part is mounted on the frame in a horizontal state. The air blow gun comprises a gun body and a second magnetic part, and the second magnetic part is mounted on the gun body. When the air blow gun is stored, the air blow gun is below the first magnetic part, and the second magnetic part faces the first magnetic part. The second magnetic part and the first magnetic part have the same polarity opposite to each other, generating a like-sex attraction force, and the like-sex attraction force is balanced with the gravity of the air blow gun, so that the gun body of the air blow gun is suspended at a predetermined position below the first magnetic part.

[0008] In an implementable solution, the suspended air blow gun device further includes a position sensor, which is mounted on the frame; wherein when the gun body of the air blow gun enters a predetermined position below the first magnetic member, the gun body enters a sensing range of the position sensor.

[0009] In an implementable scheme, the suspended air blow gun device also includes a warning device, which is connected to the position sensor signal; when the gun body of the air blow gun enters the sensing range of the position sensor, the warning device sends a first warning signal; when the gun body of the air blow gun does not enter the sensing range of the position sensor, the warning device sends a second warning signal.

[0010] In an implementable solution, the warning device includes a first signal light and a second signal light; when the gun body of the air blow gun enters the sensing range of the position sensor, the first signal light is on; when the gun body of the air blow gun does not enter the sensing range of the position sensor, the second signal light is on.

[0012] The first docking magnetic member and the second docking magnetic member are symmetrically mounted on both sides of the gun body of the air blowing gun; the first side magnetic member and the second side magnetic member are mounted on the frame in a facing manner;

[0013] When the air blowing gun is suspended below the first magnetic part, the gun body is between the first side magnetic part and the second side magnetic part, and the first docking magnetic part and the first side magnetic part are oppositely polarized and repel each other, and the second docking magnetic part and the second side magnetic part are oppositely polarized and repel each other;

[0014] The repulsive force between the first mating magnetic component and the first side magnetic component is balanced with the repulsive force between the second mating magnetic component and the second side magnetic component.

[0015] In an implementable solution, the frame includes a top panel, a bottom panel and side wall panels; the top panel closes the top of the frame, and the bottom panel closes the bottom of the frame; the side wall panels close part of the side of the frame and retain a side opening for taking and placing the blow gun.

[0016] In one feasible solution, the side wall plate is a transparent plate.

[0017] In an implementable scheme, a mounting hole is provided on the bottom panel, and a pipe joint is sealed and installed in the mounting hole; the air blow gun includes a spiral telescopic tube, one end of which is connected to the air inlet on the gun body, and the other end of which is connected to the opening of the pipe joint located on the upper side of the bottom panel, and the opening of the pipe joint located on the lower side of the bottom panel is used to connect to the air supply device.

Finally, the same-sex attraction force between the second magnetic part and the first magnetic part is balanced with the gravity of the air blow gun, so that the air blow gun is suspended under the first magnetic part. Therefore, even if the air blow gun is held in one hand, the guidance can be successfully completed and the suspended storage can be achieved with the help of the same-sex attraction force between the second magnetic part and the first magnetic part, which simplifies the operation and helps the staff focus on the other hand to prevent the products and other items in the other hand from falling and being damaged.

[0022] At the same time, because the air blow gun is suspended and stored in a predetermined position, the gun body does not contact other structures, thus eliminating unnecessary friction between the air blow gun and other structures, reducing dust and other particles generated by friction, helping to keep the working environment clean and reduce the possibility of secondary pollution.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0036] like Figure 1 , Figure 2 , Figure 3 As shown, the present embodiment provides a suspended air blow gun device, including a frame 1, a first magnetic component 2 and an air blow gun 3. The first magnetic component 2 is mounted on the frame 1 in a horizontal state. The air blow gun 3 includes a gun body 31 and a second magnetic component 32, and the second magnetic component 32 is mounted on the gun body 31. When the air blow gun 3 is stored, the air blow gun 3 is below the first magnetic component 2, and the second magnetic component 32 faces the first magnetic component 2. The second magnetic component 32 is opposite to the first magnetic component 2 in polarity, generating a like-sex attraction force, and the like-sex attraction force is balanced with the gravity of the air blow gun 3, so that the gun body 31 of the air blow gun 3 is suspended at a predetermined position below the first magnetic component 2. It should be noted that the shape of the magnetic surface of the second magnetic component 32 and the first magnetic component 2 is generally the same, so as to provide a better magnetic alignment guiding effect.

[0037] like Figure 2 As shown, in the suspended air blowing gun device of the present application, when the air blowing gun 3 is stored, the staff only needs to move the second magnetic part 32 of the air blowing gun 3 closer to the direction of the first magnetic part 2 to within a certain distance, and then the magnetic attraction can be automatically completed under the same-sex attraction force between the second magnetic part 32 and the first magnetic part 2. Finally, the same-sex attraction force between the second magnetic part 32 and the first magnetic part 2 is balanced with the gravity of the air blowing gun 3, so that the air blowing gun 3 is suspended below the first magnetic part 2. Therefore, even if the air blowing gun 3 is held in one hand, the guidance can be successfully completed and the suspended storage can be realized with the help of the same-sex attraction force between the second magnetic part 32 and the first magnetic part 2, which simplifies the operation and helps the staff focus on the other hand to prevent the products and other items in the other hand from falling and being damaged.

[0038] At the same time, because the air blow gun 3 is suspended and stored in a predetermined position, the gun body 31 does not contact other structures, thereby preventing the air blow gun 3 from generating unnecessary friction with other structures and reducing dust and other particles generated by friction, which helps to keep the working environment clean and reduce the possibility of secondary pollution.

[0039] In this embodiment, if Figure 1 , Figure 2 , Figure 4 As shown, the suspended air blow gun device may further include a position sensor 4 mounted on the frame 1 ; wherein, when the gun body 31 of the air blow gun 3 enters a predetermined position below the first magnetic member 2 , the gun body 31 enters the sensing range of the position sensor 4 .

[0040] In this embodiment, the suspended air blowing gun device may further include a warning device, which is connected to the position sensor 4 by signal. When the gun body 31 of the air blowing gun 3 enters the sensing range of the position sensor 4, the warning device sends a first warning signal. When the gun body 31 of the air blowing gun 3 does not enter the sensing range of the position sensor 4, the warning device sends a second warning signal. The warning device may be a sound alarm, a light alarm, a vibration alarm, etc.

[0041] For example, in this embodiment, if Figure 4 As shown, the warning device may include a first signal light 51 and a second signal light 52. When the gun body 31 of the air blowing gun 3 enters the sensing range of the position sensor 4, the first signal light 51 is on; when the gun body 31 of the air blowing gun 3 does not enter the sensing range of the position sensor 4, the second signal light 52 is on.

[0042] In this embodiment, if Figure 5 , Figure 6 and Figure 7As shown, the suspended air blowing gun device may further include a first side magnetic member 61 and a second side magnetic member 62 of exactly the same shape, and the air blowing gun 3 may further include a first docking magnetic member 33 and a second docking magnetic member 34 of exactly the same shape, and the first docking magnetic member 33 and the second docking magnetic member 34 are also exactly the same shape as the first side magnetic member 61 and the second side magnetic member 62. The first docking magnetic member 33 and the second docking magnetic member 34 are symmetrically mounted on both sides of the gun body 31 of the air blowing gun 3, and the first side magnetic member 61 and the second side magnetic member 62 are mounted on the frame 1 in a facing manner. When the air blowing gun 3 is suspended below the first magnetic member 2, the gun body 31 is between the first side magnetic member 61 and the second side magnetic member 62, and the first docking magnetic member 33 and the first side magnetic member 61 are oppositely polarized and repel each other, and the second docking magnetic member 34 and the second side magnetic member 62 are oppositely polarized and repel each other. The repulsive force between the first docking magnetic member 33 and the first side magnetic member 61 is balanced with the repulsive force between the second docking magnetic member 34 and the second side magnetic member 62 , so that the air blowing gun 3 maintains a stable suspended posture.

[0043] In this embodiment, if Figure 8 As shown, the frame 1 may include a top panel 11, a bottom panel 12 and a side wall panel 13. The top panel 11 closes the top of the frame 1, and the bottom panel 12 closes the bottom of the frame 12. The side wall panel 13 closes part of the side of the frame 1 and retains a side opening 14 for taking out the air blowing gun 3.

[0044] In this embodiment, the side wall plate 13 may be a transparent plate to facilitate taking out and observation.

[0045] In this embodiment, if Figure 8 As shown, a mounting hole may be provided on the bottom panel 12, and a pipe joint 7 is sealed and installed in the mounting hole. The air blowing gun 3 includes a spiral telescopic tube 35, one end of which is connected to the air inlet on the gun body 31, and the other end of which is connected to the opening of the pipe joint 7 located on the upper side of the bottom panel 12. The opening of the pipe joint 7 located on the lower side of the bottom panel 12 is used to connect the air supply device.

[0046] In this embodiment, if Fig. 9 As shown, the frame 1 includes an elastic sheet 15, and the elastic sheet 15 covers the side opening 14. The elastic sheet 15 can be made of a low-dust-generating and wear-resistant elastic material. A long gap 151 extending in the vertical direction is provided in the middle of the elastic sheet 15, so that after the air blow gun 3 is taken out, it automatically maintains a nearly closed state, so that the air blow gun 3 can be in a relatively closed environment and kept clean.

[0047] In this embodiment, the gas medium blown out by the air blowing gun 3 may be clean nitrogen.

[0048] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
