[0002] The automobile glass sealing rubber strip is one of the necessary accessories when the automobile glass is installed and used, and can play a sealing and waterproof role after being pasted with the automobile glass. Since the sealing rubber strip used on the automobile glass is adapted to the shape of the automobile glass, some of the sealing rubber strips have special structures, and such sealing rubber strips generally require positioning using a mold and then heating to melt and bond two sealing rubber strips into a firm rubber strip whole, and then cutting to make the appearance neat and consistent.

[0029] Please refer to Figures 1 to 5The embodiment of the present application provides a cleaning device for cleaning a sealing strip 200, in particular a sealing rubber strip. The sealing rubber strip is a common sealing element in an automobile, most of which is made of rubber material and mainly realizes sealing by using the elastic deformation of rubber. Further, the cleaning device comprises a cleaning container 10 for storing cleaning liquid, a fixing structure 20 arranged below the cleaning container 10, and a cleaning element 30 fixed to the fixing structure 20. The cleaning element 30 is made of a water-absorbing material and is used for rubbing the surface of the sealing strip 200 to clean the sealing strip 200. The cleaning container 10 is provided with a liquid outlet for the cleaning liquid to flow out. The cleaning liquid flowing out of the liquid outlet drips on the cleaning element 30 under the action of gravity, so that the cleaning element 30 is kept in a wet state.

[0030] Understandably, the cleaning container 10 and the fixing structure 20 are arranged in a vertical direction. The liquid outlet of the cleaning container 10 is arranged at the bottom of the cleaning container 10. The cleaning liquid in the cleaning container 10 forms droplets through the liquid outlet. The droplets fall downward under the action of gravity and finally drip on the cleaning element 30.

[0031] In the embodiment of the present application, the cleaning element 30 is made of a water-absorbing material. Specifically, the cleaning element 30 can be made of a fiber material, and the fiber material has a special fiber structure inside, so that the fiber structure has the ability to absorb and hold liquid molecules. Therefore, when the cleaning liquid continuously drips on the cleaning element 30, the cleaning element 30 can fully absorb the cleaning liquid and keep a wet state, so as to ensure the cleaning effect of the cleaning element 30 and improve the cleaning effect. Alternatively, the cleaning liquid of the present application can be water or a special cleaning agent for cleaning the sealing strip 200.

[0032] Alternatively, the cleaning element 30 can be made of natural fiber materials such as cotton or hemp. The fiber surface is easy to adsorb liquid molecules and has natural hydrophilicity. The cleaning element 30 can also be made of synthetic fiber materials such as polyester or nylon. The surface thereof is usually specially treated to form a hydrophilic treatment layer. Of course, in other possible embodiments, the cleaning element 30 can also be a specially treated textile material. For example, cotton textiles can be treated by enzymes to fully expand the fiber surface of the fabric and increase the contact area between the fiber and the water, thereby improving the water absorption. A hydrophilic treatment agent can also be introduced into the synthetic fiber material to make the surface of the textile have better water absorption.

[0033] It can be understood that, since the shape of the sealing strip 200 needs to be adapted to the appearance of the automobile, the surface of the sealing strip 200 is usually irregular, and therefore when the cleaning piece 30 is made of a fibrous material, the cleaning piece 30 has softness, and when the cleaning piece 30 is in contact with the surface of the sealing strip 200, a slight deformation is generated so as to be adapted to the surface of the sealing strip 200, thereby further improving the cleaning effect. Moreover, since the inside of the sealing strip 200 is usually provided with a metal framework, the cleaning piece 30 has softness, and therefore hard contact with the sealing strip 200 can be avoided, thereby avoiding damage to the metal framework inside the sealing strip 200.

[0034] The cleaning device provided in the present application can fix the cleaning piece 30 by the fixing structure 20, and in use, the operator can contact the sealing strip 200 with the cleaning piece 30 and pull the sealing strip 200 in a certain direction, so that the cleaning piece 30 is rubbed with the surface of the sealing strip 200 to clean the surface of the sealing strip 200, which is simple and convenient to operate, and the cleaning liquid of the cleaning container 10 can be dropped on the cleaning piece 30 through the liquid inlet 24 to keep the cleaning piece 30 in a wet state, without manually pouring the cleaning liquid on the cleaning piece 30, thereby further improving the cleaning efficiency of the sealing strip 200.

[0035] In some embodiments, the cleaning device further comprises a buffer piece 40 for slowing down the flow rate of the liquid, and the buffer piece 40 is arranged between the liquid outlet and the cleaning piece 30, so that the cleaning liquid flowing out of the liquid outlet flows through the buffer piece 40 and is guided to the cleaning piece 30 through the buffer piece 40.

[0036] By arranging the buffer piece 40, when the cleaning liquid flows through the buffer piece 40, the buffer piece 40 can slow down the flow rate of the cleaning liquid, thereby slowing down the speed of the cleaning liquid dropping on the cleaning piece 30, avoiding the cleaning piece 30 being too wet, causing waste of the cleaning liquid, and helping to save costs.

[0037] In some embodiments, the buffer piece 40 is in a strip structure, the buffer piece 40 is made of a fibrous material, one end of the buffer piece 40 extends into the liquid outlet, and the other end of the buffer piece 40 extends towards the cleaning piece 30.

[0038] In this way, when the cleaning liquid flows through the buffer piece 40, the cleaning liquid can slowly penetrate the buffer piece 40, thereby achieving slow flow, so as to hinder the flow rate of the cleaning liquid. Moreover, since the buffer piece 40 is in a strip structure, the cleaning liquid in the buffer piece 40 finally flows out from the bottom end of the buffer piece 40, thereby guiding the flow direction of the cleaning liquid. Alternatively, the buffer piece 40 can be a cotton strip or a cloth strip.

[0039] In this embodiment, the buffer 40 is made of fibrous material, which has a special fibrous structure that allows it to absorb and retain liquid molecules. Therefore, when cleaning droplets flow through the buffer 40, the liquid can slowly penetrate the buffer 40, thereby achieving slow flow and improving the buffering effect of the buffer 40.

[0040] Optionally, the cushioning element 40 can be made of natural fiber materials, such as cotton or hemp, whose fiber surfaces easily adsorb liquid molecules and have natural hydrophilicity. The cushioning element 40 can also be made of synthetic fiber materials, such as polyester or nylon, whose surfaces are typically treated to form a hydrophilic layer. Of course, in other possible embodiments, the cushioning element 40 can also be a specially treated textile material. For example, for cotton textiles, enzyme treatment can fully expand the surface of the fabric fibers, increasing the contact area between the fibers and water, thereby improving water absorption. Alternatively, a hydrophilic treatment agent can be introduced into the synthetic fiber material to give the textile surface better water absorption.

[0041] In other possible implementations, such as Figure 5 As shown, the buffer 40 can be a hollow structure with a cavity. The buffer 40 is connected to the bottom of the cleaning container 10. The cavity of the buffer 40 is connected to the liquid outlet of the cleaning container 10. The cavity of the buffer 40 may include an inlet section 41 and a capillary section 42 connected in sequence. The cleaning liquid flowing out from the liquid outlet passes through the inlet section 41 and then flows out through the capillary section 42.

[0042] The inner diameter of the inlet section 41 is larger than that of the capillary section 42. After the cleaning fluid flows out of the outlet, it first flows into the inlet section 41, and then into the capillary section 42. The inner diameter of the capillary section 42 decreases sharply, causing capillary action; the capillary section 42 is equivalent to a capillary tube. Specifically, in the capillary section 42, the surface of the cleaning fluid is concave, exerting a pulling force on the liquid below, which overcomes the liquid's gravity and downward force, keeping the cleaning fluid within the capillary section 42. Thus, the upward pulling force of the cleaning fluid in the capillary section 42 slows down the dripping speed.

[0043] Understandably, the inner diameter of capillary segment 42 should have a significant difference from the inner diameter of inlet segment 41. This makes capillary action more likely to occur when the liquid flows to capillary segment 42. Of course, the ratio of the inner diameter of inlet segment 41 to the inner diameter of capillary segment 42 cannot be too small, otherwise the inner diameter of capillary segment 42 will be too large and will not be able to prevent liquid from dripping. The ratio of the inner diameter of inlet segment 41 to the inner diameter of capillary segment 42 cannot be too large either, otherwise the inner diameter of capillary segment 42 will be too small. While a small inner diameter of capillary segment 42 can prevent liquid from dripping, it may stop the cleaning fluid from dripping altogether, requiring excessive pressure to achieve normal dripping.

[0044] In addition, the inner wall of the liquid inlet section 41 and the inner wall of the capillary section 42 are connected by a conical surface, which can cause the cleaning liquid to adhere to the conical surface, thereby slowing down the flow of the cleaning liquid and further hindering the flow of the cleaning liquid.

[0045] In some embodiments, the fixing structure 20 has a cleaning channel 23 through which the sealing strip 200 passes, the cleaning channel 23 forms an opening 25 on both sides of the fixing structure 20, the cleaning member 30 is arranged in the cleaning channel 23, and the fixing structure 20 is further provided with a liquid inlet 24 in communication with the cleaning channel 23, and the cleaning liquid flowing out of the liquid outlet drips on the cleaning member 30 through the liquid inlet 24.

[0046] In the embodiments of the present application, the cleaning member 30 is arranged in the cleaning channel 23, and the cleaning channel 23 forms an opening 25 at both ends, which facilitates an operator to hold the sealing strip 200, pass one end of the sealing strip 200 through the opening 25 on one side of the cleaning channel 23, and pass out from the opening 25 on the other side of the cleaning channel 23, and since the cleaning member 30 is arranged in the cleaning channel 23 and is soaked with the cleaning liquid, when the sealing strip 200 passes through the cleaning channel 23, the cleaning member 30 will contact and rub against the surface of the sealing strip 200, thereby cleaning the surface of the sealing strip 200.

[0047] In some embodiments, the fixing structure 20 includes a first clamping block 21 and a second clamping block 22 rotatably connected with the first clamping block 21, and the end faces of the first clamping block 21 and the second clamping block 22 close to each other are provided with clamping grooves, and the clamping grooves on the first clamping block 21 and the clamping grooves on the second clamping block 22 jointly form the cleaning channel 23.

[0048] The first clamping block 21 and the second clamping block 22 are rotatably connected, thereby facilitating the opening of the fixing structure 20, exposing the cleaning channel 23, and facilitating the replacement of the cleaning member 30 in the cleaning channel 23.

[0049] Optionally, the edges of the first clamping block 21 and the second clamping block 22 are provided with hinges, and thus the rotatable connection of the first clamping block 21 and the second clamping block 22 can be realized through the hinges.

[0050] In some embodiments, the cleaning member 30 includes a first cleaning block 31 and a second cleaning block 32, and the first cleaning block 31 and the second cleaning block 32 are respectively accommodated in the clamping grooves on the first clamping block 21 and the second clamping block 22, and when the sealing strip 200 passes through the cleaning channel 23, the first cleaning block 31 and the second cleaning block 32 jointly clamp the sealing strip 200 to clean the surface of the sealing strip 200.

[0051] It can be understood that the first cleaning block 31 and the second cleaning block 32 can protrude from the opening 25 of the clamping groove, so that when the first clamping block 21 and the second clamping block 22 are closed, the pressing force between the first cleaning block 31 and the second cleaning block 32 is large, and the clamping force of the sealing strip 200 is large, thereby further improving the cleaning effect on the sealing strip 200.

[0052] In some embodiments, the cleaning device further comprises a holding structure 50 connected to one end of the cleaning container 10 towards the fixed structure 20, and the holding structure 50 is provided with a clamping channel for the buffer 40 to pass through, and the clamping channel is in communication with the liquid outlet.

[0053] By providing the holding structure 50, the position of the buffer 40 is more stable and cannot be offset, thereby further ensuring the guiding effect of the buffer 40 on the flow of cleaning liquid. In particular, when the buffer 40 is made of a fiber material, i.e. the buffer 40 is a cotton strip or a cloth strip, the state of the buffer 40 is relatively unstable, and therefore the holding structure 50 can support the buffer 40 and also protect the buffer 40.

[0054] In some embodiments, the cross section of the clamping channel is tapered in the direction of the cleaning container 10 towards the fixed structure 20. That is, the inner diameter of the clamping channel near the end of the cleaning container 10 is larger, thereby facilitating connection with the cleaning container 10, and the inner diameter of the clamping channel near the fixed structure 20 is smaller, thereby further ensuring the clamping effect of the buffer 40 and avoiding shaking of the buffer 40.

[0055] In some embodiments, as shown in Figure 4 The holding structure 50 comprises a first segment structure 51 and a second segment structure 52 connected to each other, both the first segment structure 51 and the second segment structure 52 are hollow structures with cavities, the cavities of the first segment structure 51 and the second segment structure 52 are both tapered hole structures, the included angle of the two generatrices of the cross section of the cavity of the first segment structure 51 is a first angle, the included angle of the two generatrices of the cross section of the cavity of the second segment structure 52 is a second angle, and the first angle is smaller than the second angle.

[0056] In some embodiments, the cleaning device further comprises a support frame 60, the support frame 60 comprises a support platform 61 for placing the fixed structure 20 and a support rod 62 connected to the support platform 61, the support rod 62 extends in the vertical direction and is used to support the cleaning container 10 so that the cleaning container 10 is located above the fixed structure 20.

[0057] The support frame 60 can make the fixing structure 20 and the cleaning container 10 into an integral structure, so that the relative position of the fixing structure 20 and the cleaning container 10 is more stable, and the fixing structure 20 and the cleaning container 10 as a whole are convenient to carry and move. The support frame 60 can also support the holding structure 50, so that the holding structure 50 is more stable.

[0058] Specifically, the support frame 60 can be connected with a fixing ring 63, and the fixing ring 63 is sleeved outside the cleaning container 10 and the holding structure 50. Since the side surfaces of the cleaning container 10 and the holding structure 50 are both circumferential structures, the fixing ring 63 can be better fitted with the outer walls of the cleaning container 10 and the holding structure 50, thereby improving the stability of the fixing of the cleaning container 10 and the holding structure 50.

[0059] The application also provides an automobile sealing strip production line, which comprises the cleaning device. The specific structure of the cleaning device is referred to the above-mentioned embodiments. Since the automobile sealing strip production line adopts all the technical solutions of the above-mentioned embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0060] In summary, the cleaning device provided by the application can fix the cleaning piece 30 by the fixing structure 20. In use, the operator can contact the sealing strip 200 with the cleaning piece 30 and pull the sealing strip 200 in a certain direction, so that the cleaning piece 30 rubs against the surface of the sealing strip 200 to clean the surface of the sealing strip 200. The operation is simple and convenient, and the cleaning liquid of the cleaning container 10 can drop on the cleaning piece 30 through the liquid inlet 24 to keep the cleaning piece 30 in a wet state, so that the cleaning liquid does not need to be manually poured on the cleaning piece 30, thereby further improving the cleaning efficiency of the sealing strip 200.

[0061] The above is only an optional embodiment of the application and is not used to limit the application. The application can have various changes and modifications for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the scope of claims of the application.
