Description

Technical Field

[0001] This utility model relates to the field of ultraviolet light equipment technology, and in particular to an ultraviolet light cleaning device. Background Technology

[0002] Ultraviolet (UV) cleaning technology refers to the removal of organic matter adhering to the surface of materials using the photosensitive oxidation of organic compounds. Before processes such as coating and photoresist application, the substrate surface often needs to be irradiated to clean it. Generally, during UV cleaning, the object being irradiated is placed inside an enclosure containing air. When the UV energy is sufficient, such as 172nm wavelength UV light, the oxygen in the air is irradiated by the UV light to produce ozone. When the enclosure is opened after the cleaning process is complete, the ozone inside the enclosure will be released into the environment, which is harmful to human health and pollutes the environment. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an ultraviolet cleaning device that can draw ozone generated after operation into a waste gas collection container and prevent ozone from being emitted into the outside world.

[0004] To solve the above-mentioned technical problems, this utility model provides an ultraviolet cleaning device, comprising: a housing, an exhaust pipe provided on the side of the housing, the exhaust pipe communicating with the interior of the housing, and a switch valve provided on the exhaust pipe; an air pump, the input end of the air pump being connected to the exhaust pipe, and the output end of the air pump being connected to a waste gas collection container; an ultraviolet lamp, the ultraviolet lamp being installed inside the housing, the ultraviolet lamp having an irradiation area; and a shelf, the shelf being slidably installed inside the housing, and when the shelf slides, the shelf can pass through the irradiation area.

[0005] As a preferred embodiment of this utility model, the device further includes a driving mechanism. The housing is provided with a first slide rail arranged in a horizontal direction. The first slide rail is connected to a sliding table through a first slider. The driving mechanism is connected to the sliding table and can drive the sliding table to slide back and forth in a horizontal direction. The storage platform is mounted on the sliding table.

[0006] As a preferred embodiment of this utility model, the ultraviolet lamp shines downwards, the top of the sliding table is equipped with a lifting platform that can be raised and lowered, and the storage platform is installed on the top of the lifting platform.

[0007] As a preferred embodiment of this utility model, one side of the box body is open and has an end plate that can be opened and closed. The sliding table is provided with a second slide rail arranged in the horizontal direction. The second slide rail is connected to a sliding plate through a second slider. The shelf is installed on the sliding plate. When the first slider slides to the end of the first slide rail near the opening, the sliding plate can slide through the opening.

[0008] As a preferred embodiment of this utility model, a limiting block is provided at the end of the second slide rail away from the opening, a fixing block is provided on the side of the limiting block close to the opening, and a movable block is provided at the bottom of the sliding plate. When the second slider slides to the end of the second slide rail away from the opening, the movable block is attracted to the fixing block.

[0009] As a preferred embodiment of this utility model, the box is equipped with a controller, the side indicator light of the box is electrically connected to the controller, and the indicator light and the air pump are respectively electrically connected to the controller.

[0010] As a preferred embodiment of this utility model, the interior of the platform is equipped with a heating wire, and the box is equipped with a temperature sensor for detecting the temperature of the object being illuminated.

[0011] As a preferred embodiment of this utility model, the box body is provided with a partition plate, which divides the interior of the box body into an electrical control area and a working area. The ultraviolet lamp is installed in the electrical control area, and the shelf is located in the working area.

[0012] This utility model provides an ultraviolet cleaning device. Compared with the prior art, its advantages are as follows: During operation, the object to be irradiated is first placed on a platform, and then the platform is slid back and forth. As the platform slides, it can pass through the irradiation area. When passing through the irradiation area, the ultraviolet lamp can irradiate the object on the platform to achieve the effect of ultraviolet cleaning. The back-and-forth sliding of the platform allows it to pass through the irradiation area repeatedly, which helps to ensure that the irradiation effect on various parts of the object is consistent. After irradiation is completed, the switch valve is opened, and the air pump works to draw the gas in the chamber into the waste gas collection container, thereby preventing the ozone generated during operation from being emitted into the outside.

Detailed Implementation

[0014] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0015] like Figure 1-3 As shown, a preferred embodiment of the ultraviolet cleaning device of this utility model includes: a housing 1, an exhaust pipe 11 on the side of the housing 1, the exhaust pipe 11 communicating with the interior of the housing 1, and a switch valve (not shown in the figure) on the exhaust pipe 11. In this embodiment, for ease of operation, the switch valve is a solenoid valve; a vacuum pump (not shown in the figure), the input end of the vacuum pump is connected to the exhaust pipe 11, and the output end of the vacuum pump is connected to a waste gas collection container (not shown in the figure); an ultraviolet lamp 2, which is installed inside the housing 1 and has an irradiation area; and a shelf 3, which is slidably installed inside the housing 1. When the shelf 3 slides, it can pass through the irradiation area.

[0016] The working principle of this embodiment is as follows: During operation, the object to be irradiated is first placed on the platform 3, and then the platform 3 is slid back and forth. As the platform 3 slides, it can pass through the irradiation area. When passing through the irradiation area, the ultraviolet lamp 2 can irradiate the object on the platform 3 to achieve the effect of ultraviolet cleaning. The back and forth sliding of the platform 3 allows it to pass through the irradiation area repeatedly, which helps to ensure that the irradiation effect of each part of the object is consistent. After the irradiation is completed, the switch valve is opened, and the air pump works to draw the gas in the chamber 1 into the exhaust gas collection container, thereby preventing the ozone generated during operation from being emitted into the outside.

[0017] For example, see Figure 3-5The device also includes a drive mechanism 4. The housing 1 is provided with a first slide rail 31 arranged in a horizontal direction. The first slide rail 31 is connected to a sliding table 32 through a first slider 311. The drive mechanism 4 is connected to the sliding table 32 and can drive the sliding table 32 to slide back and forth in a horizontal direction. The shelf 3 is installed on the sliding table 32. The drive mechanism 4 drives the sliding table 32 to slide back and forth in a horizontal direction, thereby realizing the reciprocating sliding of the shelf 3. In this embodiment, there is a drive motor, a drive wheel, a driven wheel, a synchronous belt, and a connecting block. The output end of the drive motor is connected to the drive wheel. The axes of the drive wheel and the driven wheel are respectively arranged in a longitudinal direction. The drive wheel is connected to the driven wheel through a synchronous belt. A connecting block is fixed on the synchronous belt. The connecting block is located between the drive wheel and the driven wheel. The connecting block is fixedly connected to the sliding table 32. The drive motor drives the drive wheel to rotate, thereby driving the connecting block and the sliding table 32 to move in a horizontal direction.

[0018] For example, see Figure 3-5 The UV lamp 2 shines downwards, and the top of the sliding table 32 is equipped with an adjustable lifting platform 33, which can adjust the height of the lifting platform 33. It should be noted that the lifting platform 33 is a mature product on the market, that is, existing technology, and its specific structure will not be described in detail here. The storage table 3 is installed on the top of the lifting platform 33. Since the lifting platform 33 can be adjusted, the vertical height between the storage table 3 and the UV lamp 2 can be adjusted to meet the usage requirements of different sized objects.

[0019] For example, see Figure 2-5 The box body 1 has an opening on one side and is provided with an end plate 12 that can be opened and closed. The sliding table 32 is provided with a second slide rail 34 arranged in the horizontal direction. The second slide rail 34 is connected to a sliding plate 35 through a second slider 341. The shelf 3 is installed on the sliding plate 35. When the first slider 311 slides to the end of the first slide rail 31 near the opening, the sliding plate 35 can slide through the opening and move to the outside of the box body 1. After opening the end plate 12, the first slider 311 is first slid to the end near the opening through the drive mechanism 4, and then the sliding plate 35 is manually pulled so that the shelf 3 moves through the opening to the outside of the box body 1, so that the object to be photographed can be placed on the shelf 3 or removed from the shelf 3.

[0020] For example, see Figure 2 and 6The second slide rail 34 is provided with a limiting block 36 at the end away from the opening, and a fixed block 361 is provided on the side of the limiting block 36 near the opening. The bottom of the sliding plate 35 is provided with a movable block 351. When the second slider 341 slides to the end of the second slide rail 34 away from the opening, the movable block 351 is attracted to the fixed block 361 (for example, the movable block 351 and the fixed block 361 are two magnets that attract each other). Under normal conditions, the second slider 341 is located at the end of the second slide rail 34 away from the opening, that is, the movable block 351 and the fixed block 361 are attracted to each other, which can prevent the sliding block from accidentally sliding during the operation and causing the table 3 to move. By manually pulling the sliding plate 35, the movable block can be separated from the fixed block 361, so as to realize the sliding of the sliding plate 35.

[0021] For example, see Figure 1 The housing 1 is equipped with a controller and a side indicator light 13. The indicator light 13 and the air pump are electrically connected to the controller. When the ultraviolet lamp 2 or the air pump is working, the indicator light 13 remains lit. Only when both the ultraviolet lamp 2 and the air pump are stopped will the controller turn off the indicator light 13. Therefore, the indicator light 13 clearly indicates whether the device is working, so as to prevent the ozone from being released into the outside world when the housing 1 is opened during operation.

[0022] For example, see Figure 4 The interior of the shelf 3 is equipped with a heating wire (not shown in the figure), which can heat the shelf 3 and thus heat the object to be irradiated on the shelf 3. The housing 1 is equipped with a temperature sensor 5 for detecting the temperature of the object to be irradiated. In this embodiment, the temperature sensor 5 is an infrared temperature sensor 5, which is installed above the shelf 3. Some objects to be irradiated need to be heated to a specific temperature before being irradiated with ultraviolet light. The arrangement of the heating wire and the temperature sensor 5 can realize the heating of the object to be irradiated and ensure that the temperature of the object to be irradiated reaches the required level.

[0023] For example, see Figure 3 The housing 1 is provided with a partition 14, which divides the interior of the housing 1 into an electrical control area 15 and a working area 16. The ultraviolet lamp 2 is installed in the electrical control area 15, and the shelf 3 is located in the working area 16. The electrical components are installed in the electrical control area 15 and separated from the working area 16 to reduce the impact of the ultraviolet lamp 2 on the electrical components when it is working. In order to help dissipate heat from the electrical control area 15, in this embodiment, a cooling fan is provided on the side wall of the electrical control area 15. Since the electrical control area 15 is separated from the working area 16, the ozone generated during operation will not be discharged to the outside through the cooling fan.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
