DETAILED DESCRIPTION

[0032] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0033] First embodiment

[0034] like Figures 1-6 As shown, the cleaning device for automobile metal sealing sheets according to the first embodiment of the present invention comprises:

[0035] Cleaning pool 1, the top of the cleaning pool 1 is open;

[0036] The surrounding frame 2 is arranged just above the bottom of the cleaning tank 1. The surrounding frame 2 includes at least two surrounding plates 21 distributed horizontally and arranged vertically. At least three transverse axes 22 extending along the distribution direction of the surrounding plates 21 are provided between adjacent surrounding plates 21. The transverse axes 22 and the surrounding plates 21 enclose an surrounding cavity, which is used to temporarily store workpieces. At least one of the two ends of the transverse axis 22 is detachably connected to the surrounding plates 21.

[0037] The rotating assembly 3 is used to drive the surrounding frame 2 to rotate, and the rotation center line is parallel to the distribution direction of the surrounding disk 21;

[0038] The lifting component 4 has an output end connected to the surrounding frame 2 through the rotating component 3 to drive the surrounding frame 2 to enter and exit the cleaning tank 1.

[0039] When the device is used, the lifting assembly 4 first drives the surrounding frame 2 to move upward to the top of the cleaning tank 1 through the rotating assembly 3, and then one of the horizontal shafts 22 in the surrounding frame 2 is removed from between the adjacent surrounding plates 21, so that the surrounding frame 2 is opened, making it convenient to place the workpiece to be cleaned, that is, the automobile metal sealing sheet, into the surrounding frame 2. Then, the two ends of the removed horizontal shaft 22 are connected to the surrounding plates 21 to prevent the workpiece from falling from the surrounding frame 2.

[0040] After that, the lifting assembly 4 drives the surrounding frame 2 to move downward through the rotating assembly 3, so that the surrounding frame 2 enters the cleaning tank 1, and the cleaning liquid in the surrounding frame 2 is immersed in the cleaning liquid. The rotating assembly 3 is started to drive the surrounding frame 2 to rotate. Relying on the rotation of the surrounding frame 2, the workpiece in the surrounding cavity of the surrounding frame 2 is turned over, and the cleaning liquid in the cleaning tank 1 is stirred, so that the workpiece and the cleaning liquid are fully contacted and reacted to remove impurities such as oil, particles, etc. on the surface of the workpiece, improve the cleaning effect, and thus improve the cleaning efficiency.

[0041] After cleaning is completed, the lowering component 4 drives the surrounding frame 2 to move upward to the top of the cleaning pool 1 through the rotating component 3. After that, the rotating component 3 is started, driving the surrounding frame 2 to rotate, so that the workpiece in the surrounding cavity of the surrounding frame 2 rotates, generating centrifugal force. Relying on the centrifugal force, the cleaning liquid droplets attached to the workpiece and the surrounding frame 2 are thrown off, so that the cleaning liquid droplets fall into the cleaning pool 1 below. On the one hand, it avoids the cleaning liquid dripping onto the ground and causing pollution to the surrounding environment. On the other hand, it ensures the drying of the surrounding frame 2 and the surface of the workpiece in the surrounding frame 2. There is no need for manual drying treatment, which reduces the burden on the operating workers. In addition, the dripping cleaning liquid falls into the cleaning pool 1 and can be reused, which reduces the loss of cleaning liquid and achieves energy saving.

[0042] The specific structure of the cleaning tank 1 is as follows: Figure 1-Figure 3 As shown, the cleaning tank 1 is horizontally arranged with an open top, and its length direction is parallel to the axial direction of the horizontal axis 22. End plates 12 extending along its width direction are distributed side by side at both ends of the top of the cleaning liquid 1, and downwardly extending support legs 13 are fixed under both ends of the end plates 12 to support the cleaning tank 1. A drain port is provided at the bottom of the cleaning tank 1, and the drain port is connected to a drain pipe 14. A valve 15 is provided on the drain pipe 14. After the cleaning liquid is used up, the valve 15 can be opened to discharge the used cleaning liquid through the drain pipe 14.

[0043] In order to simplify the structure of the surrounding frame 2, in the present invention, the surrounding frame 2 only includes two vertically arranged surrounding plates 21. Of course, in actual production conditions, the number of surrounding plates 21 in the surrounding frame 2 can also be other multiple numbers.

[0044] A further improvement is that the rotational centerline of the enclosure frame 2 coincides with the axis of the enclosure disk 21, and the transverse axes 22 are arranged in a circular array centered around the axis of the enclosure disk 21. This design ensures that the axis of the enclosure disk 21, the rotational centerline, and the centerline of the circular array of transverse axes 22 coincide, which helps ensure the stability of the enclosure frame 2's rotation and reduces the possibility of the center of mass of the enclosure frame 2 and the workpiece being integrated into one structure being too far away from the center of gravity, which could increase the vibration amplitude during rotation.

[0045] A further improvement is that four transverse shafts 22 are provided and only the two ends of one transverse shaft 22 are detachably connected to the surrounding plate 21 .

[0046] After adopting the above design, the number of horizontal shafts 22 is reduced to reduce the cost of the surrounding frame 2, and the gap between adjacent horizontal shafts 22 is guaranteed to avoid the gap being too small, which makes it difficult for the workpiece to be loaded into the surrounding frame 2. At the same time, it is avoided that the gap is too large, which causes the workpiece to easily fall from the gap between adjacent horizontal shafts 22 as the surrounding frame 2 rotates during the cleaning process. Since there are four horizontal shafts 22, after one of the detachable horizontal shafts 22 is removed from between the two surrounding plates 21, the workpiece can be easily taken and placed on the surrounding frame 2.

[0047] A further improvement is that both ends of the horizontal axis 22, which is detachably connected to the surrounding disk 21, are connected to the coaxial centerline with a threaded section 221, and the surrounding disk 21 is provided with a socket 211 for inserting the threaded section 221, and the threaded section 221 is connected to a screw sleeve 23, which abuts against the surrounding disk 21.

[0048] Specifically, such as Figure 5 and Figure 6 As shown, the surrounding frame 2 includes two surrounding plates 21 distributed axially along the transverse axis 23. The two surrounding plates 21 are each provided with four insertion holes 211 distributed in a circular array along the thickness direction of the two surrounding plates. The outer diameters of the four transverse axes 22 are consistent with the inner diameters of the four insertion holes 211. Among the four transverse axes 22, the lengths of three transverse axes 22 are equal to the sum of the thickness and distance of the two surrounding plates 21. The two ends of the three transverse axes 22 are welded and fixed to the inner walls of the insertion holes 22 of the two surrounding plates 21. The length of the remaining transverse axis 22 is greater than that of the other transverse axes 22. The length of the remaining three horizontal axes 22 is detachably connected to the surrounding disks 21. Specifically, the two ends of the horizontal axis 22 are also integrally connected with the coaxial centerline with threaded sections 221. During assembly, the horizontal axis 22 is passed through the insertion holes 211 of the two surrounding disks 21 to expose the threaded sections 211. Then, the screw sleeves 23 are screwed onto the threaded sections 211 so that the screw sleeves 23 abut against the surrounding disks 21. When it needs to be removed, the two screw sleeves 23 are respectively unscrewed from the two threaded sections 211 to remove the horizontal axis 222 from the two surrounding disks 21.

[0049] A further improvement is that the lifting assembly 4 includes a fixed frame 41, a lifting unit 42 and a lifting frame 43, the fixed frame 41 is fixed to the ground, the lifting unit 42 is arranged on the fixed frame 41, the output end of the lifting unit 42 is connected to the lifting frame 43, the lifting frame 43 slides on the fixed frame 41 in the vertical direction, and the rotating assembly 3 and the surrounding frame 2 are both arranged on the fixed frame 41.

[0050] Specifically, such as Figure 3 and Figure 4 As shown, the fixed frame 41 includes a base 411 fixed horizontally on the ground, and two pillars 412 are fixed above the base 411, which are axially distributed along the horizontal axis 22 and extend in the vertical direction. The top ends of the two pillars 412 are fixedly connected as a whole through a horizontal beam 413. The pillars 412 are located on one side of the cleaning pool 1, and a slide rail 414 extending in the vertical direction is provided on the side of the pillars 412 adjacent to the cleaning pool 1.

[0051] The lifting frame 43 includes a horizontal transverse rectangular frame 431 and a vertical longitudinal rectangular frame 432, which are connected as one body and the length direction is parallel to the axial direction of the horizontal axis 22. The two ends of the transverse rectangular frame 431 are fixedly connected to the two ends of the two longitudinal rectangular frames 432 by two reinforcing diagonal rods 435. The two ends of the transverse rectangular frame 431 away from the longitudinal rectangular frame 432 are provided with vertical profiles 433 extending downward and located directly above the cleaning pool 1. The rotating component 3 and the surrounding frame 2 are arranged between the two vertical profiles 433. The side of the longitudinal rectangular frame 432 adjacent to the fixed frame 41 is provided with two slides 434 extending in the vertical direction and distributed side by side along the axial direction of the horizontal axis 22. The two slides 434 correspond one-to-one with the two slide rails 414 and slide in conjunction with them.

[0052] The lifting unit 42 is a lifting cylinder, the cylinder of which extends upward in the vertical direction. The bottom end of the cylinder is fixed above the base 411, and the top end of the piston rod is fixedly connected to the longitudinal rectangular frame 432.

[0053] With the above structure, the lifting cylinder 42 acts on the longitudinal rectangular frame 432 , and the sliding bar 43 and the slide rail 414 slide together, so that the lifting frame 43 drives the rotating assembly 3 and the surrounding frame 2 to move stably up and down in the vertical direction.

[0054] A further improvement is that the rotating component 3 includes a rotating motor 31, a driving sprocket 32 ​​and a chain 33. The rotating motor 31 is connected to the output end of the lifting component 4. The output end of the rotating motor 31 is coaxially connected to the driving sprocket 32. One of the surrounding disks 21 is a driven sprocket, and the driving sprocket 32 ​​is connected to the driven sprocket through the chain 33.

[0055] Specifically, the rotating motor 31 is fixed below the horizontal rectangular frame 431, and the driving sprocket 32 ​​and the two surrounding disks 21 are connected to bearings 44. The outer rings of the bearings 44 are fixedly connected to the vertical profile 433, and the inner rings of the two bearings 44 are fixedly connected to the surrounding disk 21 coaxially, and the inner ring of the other bearing 44 is fixedly connected to the driving sprocket 32 ​​coaxially.

[0056] After adopting the above structure, the rotating motor 31 is started, driving the driving sprocket 32 ​​to rotate around its own axis, and acts on one of the surrounding plates 21 serving as the driven sprocket through the chain 33. The two surrounding plates 21 are fixedly connected by four horizontal shafts 22, causing the surrounding frame 2 to rotate.

[0057] A further improvement is that baffles 11 are provided on both sides of the top of the cleaning pool 1 and are arranged on both sides of the rotation center line of the surrounding frame 2. The baffles 11 extend along the distribution direction of the surrounding disk 21 and toward the lifting and lowering movement trajectory of the surrounding frame 2.

[0058] By setting the baffle 11, the cleaning liquid droplets thrown out when the surrounding frame 2 rotates after cleaning is completed can be blocked, so that the droplets are blocked on the baffle 11, flow downward along the baffle 11, and finally enter the cleaning pool 1. On the one hand, it avoids polluting the environment, and on the other hand, the cleaning liquid can be recycled and used, saving the amount of cleaning liquid.

[0059] A further improvement is that the horizontal distance between the top of the baffle 11 and the rotation centerline of the surrounding disk 21 is greater than the horizontal distance between the bottom of the baffle 11 and the rotation centerline of the surrounding disk 21, and the top of the baffle 11 is gradually transitioned to the bottom of the baffle 11.

[0060] Specifically, the two baffles 11 are both tilted downward, and the tilting direction is mirror-symmetrical, so that the top distance of the two baffles 11 is greater than the bottom distance of the two baffles 11, expanding the receiving range of the two baffles 11 to receive the ejected cleaning liquid droplets, and preventing the ejected cleaning liquid droplets from falling on the nearby ground and polluting the surrounding production environment.

[0061] Second embodiment

[0062] like Figure 7-10 As shown, the cleaning device for automobile metal sealing sheets according to the second embodiment of the present invention is based on the first embodiment, but differs in that:

[0063] It also includes a drying component 5, which is used to dry the surrounding frame 2 and the workpiece inside the surrounding frame 2. The drying component 5 includes a fan 51 and a blowing shell 52. The input end of the fan 51 is connected to the outside world, and the output end is connected to the inner cavity of the blowing shell 52. One side of the blowing shell 52 faces the lifting and lowering movement trajectory of the surrounding disk 21 and is densely covered with air outlet holes 5221; an electric heating element 53 is arranged in the blowing shell 52.

[0064] In this embodiment, the blowing shell 52 is in the shape of a long strip, and the length direction is axially parallel to the horizontal axis 22. The projection of the blowing shell 52 on the horizontal plane is separated from the projection of the horizontal rectangular frame 431 on the horizontal plane, thereby facilitating the lifting and lowering movement of the horizontal rectangular frame 431 and avoiding interference of the blowing shell 52 with the lifting and lowering movement of the horizontal rectangular frame 431.

[0065] The blowing shell 52 is tilted toward one side of the surrounding disk 21. Specifically, the blowing shell 52 includes an open shell 521 on one side and a shell cover 522 fixed on the open side of the shell 521. The open side of the blowing shell 52 faces the surrounding disk 21, and the blowing holes 5221 are densely distributed on the shell cover 522; the fan 51 is fixed on the beam 413, and its input end is fixed and connected to the shell 521 through a connecting pipe 54, and a filter screen 55 is provided at the output end; the electric heating element 53 is an electric heating network fixed in the shell 521.

[0066] After adopting the above design, after the workpiece is soaked and cleaned, the surrounding frame 2 is raised to the top of the cleaning pool 1 by using the lifting component 4, and the cleaning liquid droplets on the workpiece and the surrounding frame 2 are thrown out by the rotating component 3, and then the fan 51 and the electric heating element 53 are started to introduce external air, and the dust particles and impurities in the external air are filtered through the filter 55, so that the clean air enters the blowing shell 52 and contacts the energized electric heating element 53. The heating element 53 transfers heat to the air, so that the air is heated and ejected from the air outlet 5221, and the rotating component 3 controls the rotation of the surrounding frame 2 so that the hot air acts on the rotating surrounding frame 2 and the workpiece in the surrounding frame 2, so that the workpiece can quickly recover and dry, and the drying effect is guaranteed, avoiding a small amount of cleaning liquid droplets remaining on the workpiece, resulting in the residual droplets falling on the ground when the workpiece is taken out, polluting the surrounding environment.

[0067] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
