Description

Technical Field

[0001] The present application relates to the technical field of vacuum dry pump detection, and in particular to a warning light and a vacuum dry pump group. Background Art

[0002] Vacuum dry pumps are widely used in industries such as integrated circuits, solar photovoltaics, LEDs, and FPDs because they have the characteristics of no liquid working medium or sealing medium in the air duct, can continuously pump air in the range of atmospheric pressure to 10Pa, and can discharge directly into the atmosphere. Generally speaking, vacuum dry pumps are installed on the floor below the production floor for integrated circuits and solar photovoltaic chips. According to production needs, many vacuum dry pumps will be placed on this floor. When the vacuum dry pump fails, the signal light on the front panel of the vacuum dry pump will flash; at the same time, the vacuum monitoring sensor inside the host device being evacuated will detect vacuum abnormalities, so the host device will have an alarm prompt.

[0003] Traditional signal lights are mostly set on the front panel to facilitate staff to inspect the operating status of the vacuum pump. In order to keep the appearance of the vacuum dry pump neat and beautiful, multiple single-color and small signal lights are mostly used. However, due to the high density of dry pumps installed in the workshop and the surface of the indicator lights of dry pumps that have been working in the workshop for a long time, dust is easily attached to the surface, resulting in low luminous intensity of the indicator lights. Once the dry pump fails, the traditional indicator lights can only observe the operating status of the warning lights when the maintenance personnel are in front of the vacuum dry pump and are close to it. The dry pump with a fault alarm cannot be found quickly, resulting in low maintenance efficiency of the staff and difficulty in meeting the needs of maintenance personnel.

[0004] Some existing vacuum dry pumps have separate warning lights for easier observation by staff. Since there are many vacuum dry pumps in the workshop, the warning lights on the vacuum dry pumps need to be highly transparent and easy to store. However, after the existing warning lights are used, they remain in the same state as when they were used, which makes the layout of the workshop unbalanced and makes it difficult to place multiple vacuum dry pumps in the workspace. Utility Model Content

[0009] A light-emitting part is arranged in the lampshade, and the light-emitting parts are arranged in sequence along the axial direction of the fixed rod. The number of the light-emitting parts is more than two, and the connecting rod can drive the light-emitting part to fold along the rod length direction of the fixed rod, or the connecting rod and the fixed rod rotate to form a straight rod structure.

[0010] In a possible implementation, a telescopic portion is provided at one end of the lampshade close to the connecting rod, one end of the telescopic portion is connected to the lampshade, the telescopic portion matches the lampshade, and the other end of the telescopic portion is connected to the connecting rod.

[0011] In a possible implementation, a limiting portion is disposed on the lampshade, the limiting portions are disposed on the lampshade at intervals, and the limiting portions are correspondingly disposed between two adjacent light-emitting portions.

[0012] In a possible implementation, the number of the light-emitting parts is three, and the light-emitting parts are equally divided inside the lampshade; the number of the limiting parts is two, and the limiting parts are equally divided on the lampshade.

[0013] In a possible implementation, the light emitting portion is disposed on a center line of the lampshade, and one end of the connecting rod is disposed in a middle portion of the lampshade.

[0014] In a possible implementation, the telescopic portion is in a truncated cone structure, and a cross-sectional area of ​​an end of the telescopic portion close to the connecting rod is smaller than a cross-sectional area of ​​an end of the telescopic portion away from the connecting rod.

[0015] In a possible implementation, the fixing rod is vertically arranged on the top of the vacuum dry pump, and the lampshade can be rotated to a preset angle of 0 degrees to 90 degrees.

[0016] In a possible implementation manner, the ratio of the total length of the fixing rod to the total length of the lampshade is 1:5-4:7.

[0017] In a possible implementation manner, the lampshade is in a cylindrical structure, and one end of the lampshade away from the connecting rod is rounded.

[0018] According to another aspect of the present application, a vacuum dry pump group is provided, comprising the warning light described above and multiple vacuum dry pumps; pre-installation holes are provided on the tops of the multiple vacuum dry pumps, and the other end of the fixing rod of the warning light is arranged on the pre-installation hole; the light-emitting part inside the warning light is electrically connected to the main control board of the vacuum dry pump, and the total length of the warning light is less than one-third of the height of the vacuum dry pump; a display panel is provided in the middle and upper part of the front panel of the vacuum dry pump, an emergency stop button is provided on the side panel of the vacuum dry pump, and a sliding wheel is provided at the bottom of the vacuum dry pump.

It is convenient to organize the wires, so that the line of the light-emitting part is connected to the main control board inside the vacuum dry pump. When there is a problem with the light-emitting part, the lampshade can be directly removed to inspect the lamp beads inside the lampshade. At the same time, when the vacuum dry pump is not in use, the vacuum dry pump can be folded to a position level with the top plate of the vacuum dry pump, so that the vacuum dry pump occupies a more reasonable position in the workshop.

[0022] 3. The lampshade is made of epoxy resin. Epoxy resin is dustproof, waterproof, oil-proof, anti-iron filings, anti-corrosion, and light in weight. Compared with the old warning light lampshade, the epoxy resin lampshade is not easy to be contaminated with dust, and the design is more reasonable. And the transparent epoxy resin lampshade will not affect the light intensity of the LED lamp beads in the warning light.

[0032] Figure 1 A schematic diagram showing the structure of a warning light according to an embodiment of the present application; Figure 2 1 shows a front view of a vacuum dry pump in a vacuum dry pump assembly according to an embodiment of the present application. Figure 1As shown, the warning light 10 is suitable for being arranged on the vacuum dry pump 20, comprising: a fixing rod 100, a connecting rod 200, a light-emitting part and a lampshade 300; the interior of the fixing rod 100 is a hollow structure, one end of the fixing rod 100 is longitudinally arranged on the upper part of the vacuum dry pump 20, and the other end of the fixing rod 100 is rotatably connected to one end of the connecting rod 200; the interior of the connecting rod 200 is a hollow structure, one end of the connecting rod 200 is communicated with the fixing rod 100, and the other end of the connecting rod 200 is communicated with the lampshade 300, and the material of the lampshade 300 is epoxy resin; the interior of the lampshade 300 is provided with a light-emitting part, and the light-emitting part is arranged in sequence along the axial direction of the fixing rod 100, the number of the light-emitting parts is more than two, and the connecting rod 200 can drive the light-emitting part to fold along the rod length direction of the fixing rod 100, or the connecting rod 200 and the fixing rod 100 rotate to form a straight rod structure.

[0033] The warning light 10 proposed in this embodiment is composed of a light-emitting part, a lampshade 300, a connecting rod 200 and a fixed rod 100. The light-emitting part is arranged inside the lampshade 300, and one end of the connecting rod 200 is connected to the lampshade 300, and the other end of the connecting rod 200 is rotatably connected to one end of the fixed rod 100. The other end of the fixed rod 100 is arranged on the top of the vacuum dry pump 20. The installation method is simple and easy to operate. It should also be noted that since the interior of the fixed rod 100 is a hollow structure, and one end of the fixed rod 100 is longitudinally arranged on the upper part of the vacuum dry pump 20, the other end of the fixed rod 100 is rotatably connected to one end of the connecting rod 200; the interior of the connecting rod 200 is a hollow structure, and the other end of the connecting rod 200 is connected to the lampshade 300. It is convenient to organize the wires, so that the circuit of the light-emitting part is connected to the main control board inside the vacuum dry pump 20. It should also be noted that the fixed rod 100 and the connecting rod 200 are rotatably connected through the rotating part 400. It should be further explained that the epoxy resin material has the characteristics of dustproof, waterproof, oil-proof, anti-iron filings, anti-corrosion, and light weight. Compared with the old warning light 10 lampshade 300, the new warning light 10 lampshade 300 is not easy to be contaminated by dust, and the design is more reasonable. And the transparent epoxy resin lampshade 300 will not affect the light intensity of the LED lamp beads of the warning light 10. Compared with the old warning light 10 lampshade 300, the new warning light 10 lampshade 300 is transparent, which will not affect the light intensity of the LED lamp beads and is more colorful. At the same time, the brand logo of the dry pump can also be designed and engraved inside the warning light 10, which is not only beautiful, but also has an advertising effect.

[0034] In one specific embodiment, a telescopic portion 310 is provided at one end of the lampshade 300 close to the connecting rod 200, one end of the telescopic portion 310 is connected to the lampshade 300, the telescopic portion 310 matches the lampshade 300, and the other end of the telescopic portion 310 is connected to the connecting rod 200. The telescopic portion 310 is a truncated cone structure, and the cross-sectional area of ​​the end of the telescopic portion 310 close to the connecting rod 200 is smaller than the cross-sectional area of ​​the end of the telescopic portion 310 away from the connecting rod 200. In this embodiment, it should be noted that the telescopic portion 310 is provided to facilitate compression or extension of the lampshade 300. When in use, the telescopic portion 310 is pulled out along the rod length direction of the connecting rod 200, so that the lampshade 300 occupies a larger area and is easy to observe. It is convenient for staff to observe the operation of the vacuum dry pump 20. After use, the telescopic portion 310 is squeezed along the rod length direction to reduce the area occupied by the lampshade 300, so that the layout of the use space is more concentrated.

[0035] In one specific embodiment, the lampshade 300 is provided with a limiting portion 320 , and the limiting portions 320 are arranged on the lampshade 300 at intervals, and the limiting portions 300 are correspondingly arranged between two adjacent light-emitting portions.

[0036] In one specific embodiment, the number of the light-emitting parts is three, and the light-emitting parts are equally divided inside the lampshade 300 . The number of the limiting parts 320 is two, and the limiting parts 320 are equally divided on the lampshade 300 .

[0037] In summary, it should be noted that the light-emitting portion includes a first light-emitting portion, a second light-emitting portion and a third light-emitting portion. The distance between two adjacent limit portions 320 is equal, and the first light-emitting portion, the second light-emitting portion and the third light-emitting portion are arranged in equal length inside the lampshade 300. The sum of the setting length of the first light-emitting portion, the setting length of the second light-emitting portion and the setting length of the third light-emitting portion is equal to the total length of the lampshade 300. It should also be noted that the first light-emitting portion, the second light-emitting portion and the third light-emitting portion are preferably LED light strips. The limit portion 320 separates the first light-emitting portion, the second light-emitting portion and the third light-emitting portion outside the lampshade 300, which is convenient for the operator to observe the status of different lamp layers and to handle the vacuum dry pump 20 in operation in time. And when the lengths of the first light-emitting portion, the second light-emitting portion and the third light-emitting portion are equal to the total length of the lampshade 300, the light emission of the light-emitting portion in the lampshade 300 is obvious. Since the limit portions 320 are arranged at equal intervals, the proportion of each light-emitting portion is the same and the light emission is obvious. It should be further explained that the first light-emitting part emits a red light to indicate that the vacuum dry pump 20 is in a downtime state and needs to be stopped in time. The second light-emitting part emits a yellow light to indicate that the vacuum dry pump 20 is in an alarm state. The third light-emitting part displays a green light to indicate that the vacuum dry pump 20 is in a normal operating state. It should be further explained that there is a storage bin in the middle of the interior of the lampshade 300, and the length of the storage bin is equal to the length of the lampshade 300. There are two limit parts 320, one of which is located between the first light-emitting part and the second light-emitting part, and the other limit part 320 is located between the second light-emitting part and the third light-emitting part. Since the distance between each layer of light-emitting parts is close, it is inconvenient to adjust the color, and it is easy for the lights to affect each other, causing certain interference to the judgment of the staff. Therefore, a limit part 320 is set between each light-emitting part to reduce the color interference of the light-emitting parts.

[0038] In one specific embodiment, the light emitting part is arranged on the center line of the lampshade 300, and one end of the connecting rod 200 is arranged in the middle of the lampshade 300. In this embodiment, it should be noted that the first light emitting part, the second light emitting part and the third light emitting part are all arranged in the partition compartment of the storage compartment in the lampshade 300, so that the light colors of the first light emitting part, the second light emitting part and the third light emitting part have the same intensity when observed from a distance around, which can meet the needs of operators. This makes the structure of the warning light stable and the light emission uniform.

[0039] In one specific embodiment, the fixing rod 100 is vertically arranged on the top of the vacuum dry pump 20, and the lampshade 300 can rotate at a preset angle of 0-90 degrees. In this implementation, the connecting rod 200 is preferably rotatable along the length direction of the top panel of the vacuum dry pump 20; or the connecting rod 200 is preferably rotatable along the width direction of the top panel of the vacuum dry pump 20.

[0040] In one specific embodiment, the ratio of the total length of the fixing rod 100 to the lampshade 300 is 1:5-4:7. In this embodiment, it should be noted that the ratio of the total length of the fixing rod 100 to the lampshade 300 is preferably 1:3. It should also be noted that the ratio of the length of the fixing rod 100 to the length of the connecting rod 200 is preferably 1:1.

[0041] In one specific embodiment, the lampshade 300 is in a cylindrical structure, and the end of the lampshade 300 away from the connecting rod is rounded to prevent the lampshade 300 from scratching the hands of the staff when the lampshade 300 is folded or turned over. The cylindrical structure makes the luminous intensity of each light-emitting part uniform, which does not affect the staff's observation of the use status of the vacuum dry pump.

[0042] like Figure 2 As shown, the vacuum dry pump group includes the warning light 10 and multiple vacuum dry pumps 20 mentioned above; pre-installed holes are provided on the tops of the multiple vacuum dry pumps 20, and the other end of the fixing rod 100 of the warning light 10 is arranged on the pre-installed hole; the light-emitting part inside the warning light 10 is electrically connected to the main control board of the vacuum dry pump 20, the total length of the warning light 10 is less than one-third of the height of the vacuum dry pump 20, a display panel 21 is provided in the middle and upper part of the front panel of the vacuum dry pump 20, an emergency stop button 22 is provided on the side panel of the vacuum dry pump 20, and a sliding wheel 23 is provided at the bottom of the vacuum dry pump 20.

[0043] The vacuum dry pump group proposed in this embodiment, when the dry pump fails, the vacuum dry pump group of this embodiment can still clearly observe the operating status of the vacuum dry pump group under the condition of high density of dry pumps in the workshop, and compared with the traditional warning light 10 designed on the front panel of the dry pump, the vacuum dry pump 20 in this embodiment is more convenient for maintenance personnel to find the vacuum dry pump 20 that is in use and has a fault in time, thereby improving maintenance efficiency. The first light-emitting part, the second light-emitting part and the third light-emitting part are longitudinally arranged inside the lampshade and are all electrically connected to the main control board in the vacuum dry pump. The first light-emitting part displays a green light, the second light-emitting part displays a yellow light, and the third light-emitting part displays a red light. Specifically, the green light indicates the normal operating state, the yellow light indicates the alarm state, and the red light indicates the downtime state. The warning light is rotated and folded. The warning light can be folded when the dry pump is idle, and the warning light can be erected when the dry pump is enabled. Specifically, when in use, the warning light 10 is folded upward until the warning light 10 is perpendicular to the top plate of the vacuum dry pump 20, and the operating state of the vacuum dry pump 20 at the top is judged according to the light colors of the first light-emitting part, the second light-emitting part and the third light-emitting part. When not in use, since the fixed rod 100 and the connecting rod 200 are rotatably connected, the connecting rod 200 and the lampshade 300 can be rotated downward to reduce the volume of the vacuum dry pump 20. It should also be noted that the connecting rod 200 of the present application is rotatable along the length direction of the top panel of the vacuum dry pump 20, and the sum of the lengths of the connecting rod 200 and the lampshade 300 is less than the length of the top panel of the vacuum dry pump 20; or the connecting rod 200 is rotatable along the width direction of the top panel of the vacuum dry pump 20, and the sum of the lengths of the connecting rod 200 and the lampshade 300 is less than the width of the top panel of the vacuum dry pump 20. It should be further noted that the rod length of the fixed rod 100 is less than or equal to one twelfth of the overall height of the vacuum dry pump 20. The number of sliding wheels 23 is 4, and the sliding wheels are preferably universal sliding wheels, so that when multiple vacuum dry pumps 20 fail and stop running, the failed vacuum dry pumps 20 can be moved to the repair place for the same repair. Compared with the traditional warning light design on the front panel of the dry pump, the warning light of the present application is designed on the top plate of the dry pump, which is more conspicuous and easy for operators to detect the vacuum condition.

[0044] It should be noted that although the warning light and the vacuum dry pump are introduced as examples in this application, those skilled in the art will understand that this application should not be limited to this vacuum dry pump. In fact, users can flexibly set it according to personal preferences and / or actual application scenarios, as long as it is reasonable.

[0045] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
