[0002] Automobile glass sealing strips are one of the essential accessories for the installation and use of automobile glass. After being pasted on the automobile glass, they can play a role in sealing and waterproofing. Due to the adaptation to the shape of the automobile glass, some of the sealing strips used on the automobile glass have special structures. Such sealing strips generally require the use of molds for positioning and heating, and the two sealing strips are heat-fused into a solid strip as a whole, and then cut to make the appearance neat and consistent.

[0003] When the sealing strip is hot-melted and cut, it is inevitable that the surface of the sealing strip will be contaminated with pollutants, which will affect the subsequent processing of the strip, so the sealing strip needs to be cleaned. However, in the prior art, the sealing strip can only be cleaned by the operator holding a cleaning cloth, etc. In order to keep the cleaning cloth moist, the operator needs to pour cleaning liquid on the cleaning cloth from time to time, which is troublesome and has low cleaning efficiency.

[0029] See also Figures 1 to 5The embodiment of the present application provides a cleaning device for cleaning a sealing strip 200. The sealing strip 200 is specifically a sealing rubber strip. The sealing rubber strip is a common sealing component in automobiles. Most of the sealing components are made of rubber and mainly use the elastic deformation of rubber to achieve sealing. Furthermore, the cleaning device includes a cleaning container 10 for storing a cleaning liquid, a fixed structure 20 disposed under the cleaning container 10, and a cleaning member 30 fixed to the fixed structure 20. The cleaning member 30 is made of a water-absorbing material. The cleaning member 30 is used to rub against 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 onto the cleaning member 30 under the action of gravity to keep the cleaning member 30 in a wet state.

[0030] It can be understood that the cleaning container 10 and the fixed structure 20 are spaced apart in the vertical direction, and the liquid outlet of the cleaning container 10 is set at the bottom of the cleaning container 10. The cleaning liquid in the cleaning container 10 will form droplets through the liquid outlet, and the droplets will drip downward under the action of gravity and finally drip onto the cleaning member 30.

[0031] In the embodiment of the present application, the cleaning member 30 is made of a water-absorbing material, specifically, the cleaning member 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 retain liquid molecules, so when the cleaning liquid drops continue to drip on the cleaning member 30, the cleaning member 30 can fully absorb the cleaning liquid and maintain a wet state, thereby ensuring the cleaning function of the cleaning member 30 and improving the cleaning effect. Optionally, the cleaning liquid of the present application can be clean water or a special cleaning agent for cleaning the sealing strip 200.

[0032] Optionally, the cleaning member 30 can be made of natural fiber materials, such as cotton or linen, etc., whose fiber surfaces easily absorb liquid molecules and have natural hydrophilicity; the cleaning member 30 can also be made of synthetic fiber materials, such as polyester or nylon, etc., whose surfaces are usually specially treated to form a hydrophilic treatment layer. Of course, in other possible embodiments, the cleaning member 30 can also be a specially treated textile material, such as cotton textiles, which can be fully expanded by enzyme treatment to increase the contact area between the fiber and water, thereby improving water absorption; hydrophilic treatment agents can also be introduced into synthetic fiber materials to make the textile surface more absorbent.

[0033] It is understandable that, since the shape of the sealing strip 200 needs to match the appearance of the car, the surface of the sealing strip 200 is usually irregular, so when the cleaning member 30 is made of fiber material, the cleaning member 30 is soft, and when the cleaning member 30 contacts the surface of the sealing strip 200, it will produce a slight deformation to match the surface of the sealing strip 200, thereby further improving the cleaning effect. And since the sealing strip 200 is usually provided with a metal frame inside, the cleaning member 30 is soft, which can avoid hard contact with the sealing strip 200, thereby avoiding damage to the metal frame inside the sealing strip 200.

[0034] The cleaning device provided in the present application has a fixing structure 20 that can fix the cleaning member 30. When in use, the operator can contact the sealing strip 200 with the cleaning member 30 and pull the sealing strip 200 in a certain direction to cause friction between the cleaning member 30 and the surface of the sealing strip 200, thereby cleaning the surface of the sealing strip 200. The operation is simple and convenient, and the cleaning liquid in the cleaning container 10 can drip onto the cleaning member 30 through the liquid inlet 24 to keep the cleaning member 30 moistened. There is no need to manually pour the cleaning liquid on the cleaning member 30, thereby further improving the cleaning efficiency of the sealing strip 200.

[0035] In some embodiments, the cleaning device further includes a buffer 40 for slowing down the flow rate of the liquid. The buffer 40 is disposed between the liquid outlet and the cleaning member 30 . The cleaning liquid flowing out of the liquid outlet flows through the buffer 40 and is guided by the buffer 40 to flow toward the cleaning member 30 .

[0036] By providing the buffer 40, when the cleaning liquid flows through the buffer 40, the buffer 40 can slow down the flow rate of the cleaning liquid, thereby slowing down the speed at which the cleaning liquid drops onto the cleaning member 30, avoiding the cleaning member 30 from being too wet and causing waste of cleaning liquid, which helps to save costs.

[0037] In some embodiments, the buffer member 40 is a strip-shaped structure, and the buffer member 40 is made of fiber material. One end of the buffer member 40 extends into the liquid outlet, and the other end of the buffer member 40 extends toward the cleaning member 30 .

[0038] In this way, when the cleaning liquid flows through the buffer 40, the cleaning liquid can slowly penetrate the buffer 40, thereby achieving slow flow, thereby hindering the flow rate of the cleaning liquid. And because the buffer 40 is a strip structure, the cleaning liquid in the buffer 40 eventually flows out from the bottom of the buffer 40, thereby guiding the flow direction of the cleaning liquid. Optionally, the buffer 40 can be a cotton strip or a cloth strip.

[0039] In the embodiment of the present application, the buffer 40 is 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 retain liquid molecules. Therefore, when the cleaning liquid droplets flow through the buffer 40, the liquid can slowly penetrate the buffer 40, thereby achieving slow flow, thereby improving the buffering effect of the buffer 40.

[0040] Optionally, the buffer 40 can be made of natural fiber materials, such as cotton or linen, etc., the fiber surface easily absorbs liquid molecules and has natural hydrophilicity; the buffer 40 can also be made of synthetic fiber materials, such as polyester or nylon, etc., and its surface is usually specially treated to form a hydrophilic treatment layer. Of course, in other possible embodiments, the buffer 40 can also be a specially treated textile material, such as cotton textiles, enzyme treatment can make the surface of the fabric fiber fully unfold, increase the contact area between the fiber and water, and thus improve water absorption; hydrophilic treatment agents can also be introduced into synthetic fiber materials to make the textile surface more absorbent.

[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, and the cavity of the buffer 40 can include a liquid inlet section 41 and a capillary section 42 connected in sequence. The cleaning liquid flowing out of the liquid outlet passes through the liquid inlet section 41 and then flows out through the capillary section 42.

[0042] The inner diameter of the liquid inlet section 41 is larger than the inner diameter of the capillary section 42. After the cleaning liquid flows out from the liquid outlet, the cleaning liquid first flows into the liquid inlet section 41. Then, when entering the capillary section 42, the inner diameter of the capillary section 42 decreases suddenly. Therefore, a capillary phenomenon occurs in the capillary section 42, and the capillary section 42 is equivalent to a capillary tube. Specifically, in the capillary section 42, the liquid surface of the cleaning liquid is concave, which exerts a pulling force on the liquid below, and can overcome the gravity of the liquid and the downward impulse to keep the cleaning liquid in the capillary section 42. In this way, the cleaning liquid in the capillary section 42 has an upward pulling force, so the dripping speed of the cleaning liquid can be slowed down.

[0043] It is understandable that the inner diameter of the capillary section 42 should have a large difference with the inner diameter of the liquid inlet section 41, so that when the liquid flows to the capillary section 42, it is easier to produce capillary action. Of course, the ratio of the inner diameter of the liquid inlet section 41 to the inner diameter of the capillary section 42 cannot be too small, otherwise it means that the inner diameter of the capillary section 42 is too large, which cannot prevent the liquid from dripping; the ratio of the inner diameter of the liquid inlet section 41 to the inner diameter of the capillary section 42 cannot be too large, otherwise it means that the inner diameter of the capillary section 42 is too small. Although the inner diameter of the capillary section 42 is too small to prevent the liquid from dripping, it may stop the cleaning liquid from dripping, and excessive pressure is required 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 via a conical surface, which can make the cleaning liquid sticky on 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 fixed structure 20 has a cleaning channel 23 for the sealing strip 200 to pass through, the cleaning channel 23 forms openings 25 on both side surfaces of the fixed structure 20, and the cleaning member 30 is arranged in the cleaning channel 23. The fixed structure 20 is also provided with a liquid inlet 24 connected to the cleaning channel 23, and the cleaning liquid flowing out from the liquid outlet drips onto the cleaning member 30 through the liquid inlet 24.

[0046] In the embodiment of the present application, the cleaning member 30 is arranged in the cleaning channel 23, and openings 25 are formed at both ends of the cleaning channel 23, which is convenient for the 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. Since the cleaning member 30 soaked in the cleaning liquid is arranged in the cleaning channel 23, 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 fixed structure 20 includes a first clamping block 21 and a second clamping block 22 rotatably connected to the first clamping block 21. The end surfaces of the first clamping block 21 and the second clamping block 22 that are close to each other are provided with clamping grooves. The clamping groove on the first clamping block 21 and the clamping groove on the second clamping block 22 together form a cleaning channel 23.

[0048] The first clamping block 21 and the second clamping block 22 are rotatably connected, so that the fixing structure 20 is conveniently opened to expose the cleaning channel 23 , thereby facilitating replacement of the cleaning member 30 in the cleaning channel 23 .

[0049] Optionally, hinges are provided on the edges of the first clamping block 21 and the second clamping block 22, so that the first clamping block 21 and the second clamping block 22 can be rotatably connected through the hinges.

[0050] In some embodiments, the cleaning member 30 includes a first cleaning block 31 and a second cleaning block 32, which are respectively accommodated in a clamping groove on the first clamping block 21 and a clamping groove on the second clamping block 22. 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. Therefore, when the first clamping block 21 and the second clamping block 22 are covered, the clamping force between the first cleaning block 31 and the second cleaning block 32 can be larger, so that the force of jointly clamping the sealing strip 200 is larger, thereby further improving the cleaning effect of 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 facing the fixed structure 20 , and a clamping channel for the buffer 40 to pass through is provided in the holding structure 50 , and the clamping channel is communicated with the liquid outlet.

[0053] By providing the retaining structure 50, the position of the buffer 40 can be made more stable and will not be offset, thereby further ensuring the guiding effect of the buffer 40 on the flow of the cleaning liquid, especially when the buffer 40 is made of fiber material, that is, the buffer 40 is a cotton strip or a cloth strip, the state of the buffer 40 is relatively unstable, so providing the retaining 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 gradually reduced in the direction from the cleaning container 10 to the fixed structure 20. That is, the inner diameter of the end of the clamping channel close to the cleaning container 10 is larger, so as to facilitate the connection with the cleaning container 10, while the inner diameter of the end of the clamping channel close to the fixed structure 20 is smaller, so as to further ensure the clamping effect of the buffer 40 and prevent the buffer 40 from shaking.

[0055] In some embodiments, Figure 4 As shown, the retaining structure 50 includes a first section structure 51 and a second section structure 52 that are interconnected. The first section structure 51 and the second section structure 52 are both hollow structures with cavities. The cavities of the first section structure 51 and the second section structure 52 are both conical hole structures. The angle between two generatrixes of the cross section of the cavity of the first section structure 51 is a first angle, and the angle between two generatrixes of the cross section of the cavity of the first section structure 51 is a second angle. The first angle is smaller than the second angle.

[0056] In some embodiments, the cleaning device also includes a support frame 60, which includes a support platform 61 for placing the fixed structure 20 and a support rod 62 connected to the support platform 61, and the support rod 62 extends in a vertical direction. The support rod 62 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 fixed structure 20 and the cleaning container 10 an integral structure, so that the relative position of the fixed structure 20 and the cleaning container 10 is more stable, and it is convenient to carry and move the fixed structure 20 and the cleaning container 10 as a whole. The support frame 60 can also support the holding structure 50, so that the holding structure 50 is more stable.

[0058] Specifically, a fixing ring 63 can be connected to the support frame 60, and the fixing ring 63 is sleeved on the outside of the cleaning container 10 and the holding structure 50. Since the sides of the cleaning container 10 and the holding structure 50 are both circular structures, the setting of the fixing ring 63 can better fit 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 present application also proposes an automobile sealing strip production line, which includes a cleaning device. The specific structure of the cleaning device refers to the above embodiment. Since the automobile sealing strip production line adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0060] In summary, in the cleaning device provided by the present application, the fixing structure 20 can fix the cleaning member 30. When in use, the operator can bring the sealing strip 200 into contact with the cleaning member 30 and pull the sealing strip 200 in a certain direction to cause friction between the cleaning member 30 and the surface of the sealing strip 200, thereby cleaning the surface of the sealing strip 200. The operation is simple and convenient, and the cleaning liquid in the cleaning container 10 can drip onto the cleaning member 30 through the liquid inlet 24 to keep the cleaning member 30 moistened. There is no need to manually pour the cleaning liquid on the cleaning member 30, thereby further improving the cleaning efficiency of the sealing strip 200.

[0061] The above are only optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
