[0002] In related technologies, when cleaning the inner surfaces of shell-type products, workers often use brushes or cleaning cloths, which is time-consuming, yields inconsistent cleaning results, and is labor-intensive and inefficient. Therefore, existing automated cleaning devices frequently use high-pressure air guns to blow away dust, but this often leaves residual dust or oil, resulting in unsatisfactory cleaning. Thus, improving the cleaning efficiency and effectiveness of product inner surfaces is a problem that needs to be solved. Summary of the Invention

The movement paths of the first clamping part and the second clamping part both pass through the transfer platform. The cleaning module is provided with two sets, including a first cleaning module and a second cleaning module. The first cleaning module is used to clean the first opposing surface inside the product on the first clamping part, and the second cleaning module is used to clean the second opposing surface inside the product on the second clamping part.

[0010] According to some embodiments of the present invention, the conveying mechanism is located on the side of the cleaning mechanism away from the positioning module, and includes a feeding roller and a take-up roller, wherein the feeding roller is used to unwind the cleaning belt and the take-up roller is used to wind the cleaning belt.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0022] The following is for reference. Figures 1 to 8 An internal surface cleaning device according to an embodiment of the present invention is described.

[0023] like Figures 1 to 4 As shown, an inner surface cleaning device according to an embodiment of the present invention includes: a positioning module 100, a cleaning module 200, and an entry drive mechanism 300. The positioning module 100 is provided with a clamping end for clamping and fixing a product 500. The cleaning module 200 is used to clean the inner surface of the product 500 and includes a conveying mechanism 210 and a cleaning mechanism 220. The cleaning mechanism 220 includes a cleaning frame 221, a roller assembly 222, and a cleaning belt (not shown in the figure). The roller assembly 222 is rotatably connected to the cleaning frame 221, and the cleaning belt is sleeved on the roller assembly 222. The conveying mechanism 210 is used to drive the cleaning belt to move around the roller assembly 222. The entry drive mechanism 300 is used to drive the clamping end and / or the cleaning module 200 to move so that at least a portion of the cleaning mechanism 220 can enter the port of the product 500 and clean the opposite surfaces inside the product 500 by the moving cleaning belt.

[0024] It is understood that this internal surface cleaning device includes a positioning module 100, a cleaning module 200, and an entry drive mechanism 300. In use, the clamping end of the positioning module 100 clamps and fixes one end of the product 500. Then, the entry drive mechanism 300 can drive the positioning module 100 and the cleaning module 200 to move closer together, so that the cleaning mechanism 220 in the cleaning module 200 enters the port of the product 500. The cleaning belt in the cleaning mechanism 220, which is arranged around the roller assembly 222, can rotate under the drive of the conveying mechanism 210. The cleaning belt entering the product 500 can clean the opposite surfaces inside the product 500 during the movement, thereby realizing the automated cleaning of the inner surface of the product 500. Therefore, the internal surface cleaning device of this application can automatically wipe and clean the inner surface of the product 500, improving the cleaning efficiency and cleaning effect of the inner surface of the product 500.

[0025] Specifically, the cleaning strip can be made of different types of fabrics such as non-woven fabric, or other materials that can be used for cleaning.

[0026] It should be understood that the cleaning belt can be a complete loop fitted onto the cleaning frame 221, or only a portion of it can be fitted onto the cleaning frame 221. The key is to ensure that a portion of the cleaning mechanism 220 can enter the port of the product 500 for cleaning.

[0027] Understandably, the cleaning mechanism 220 also includes a second elastic component 224. The roller assembly 222 is rotatably connected to one end of the cleaning frame 221 near the positioning module 100. The second elastic component 224 is located on the side of the roller assembly 222 facing away from the positioning module 100. The cleaning belt is sleeved on the second elastic component 224. The roller assembly 222 divides the cleaning belt into an upper cleaning section and a lower cleaning section distributed vertically. The second elastic component 224 has the elasticity to make the upper cleaning section protrude from the upper end face of the roller assembly 222 and the lower cleaning section protrude from the lower end face of the roller assembly 222, so that the cleaning belt can flexibly contact the opposite surfaces within the product 500. For example, as... Figures 4 to 5 As shown, in this embodiment, the roller assembly 222 is rotatably connected to one end of the cleaning frame 221 near the positioning module 100, thereby enabling better rotation of the cleaning belt surrounding the roller assembly 222. Simultaneously, the second elastic component 224 is disposed on the cleaning frame 221 and located on the side of the roller assembly 222 away from the positioning module 100. The second elastic component 224 has elasticity supporting the upper cleaning section of the cleaning belt protruding from the upper end face of the roller assembly 222, and also has elasticity supporting the lower cleaning section of the cleaning belt protruding from the lower end face of the roller assembly 222. This allows the upper and lower cleaning sections to flexibly abut against the inner surface of the product 500, preventing the cleaning belt from squeezing and deforming the product 500 after entering its interior. Furthermore, the elastic support of the cleaning belt against the inner surface of the product 500 enhances the cleaning force and effectiveness.

[0028] It is understood that the second elastic component 224 has two sets distributed vertically to support the upper and lower cleaning sections respectively. The second elastic component 224 includes an abutment 2241, a second elastic component 2242, and a limiting pin 2243. The cleaning rack 221 has receiving grooves 2211 that penetrate its upper and lower end faces respectively. The abutment 2241 is located on the side of the second elastic component 2242 away from the bottom of the receiving groove 2211 and protrudes from the opening of the receiving groove 2211. The abutment 2241 has a waist-shaped hole 2244 that extends vertically and penetrates horizontally. The limiting pin 2243 is fixed to the cleaning rack 221 and passes through the waist-shaped hole 2244. For example, as Figures 4 to 6As shown, in this embodiment, the second elastic component 224 includes two sets that respectively abut against the upper cleaning section and the lower cleaning section. Each set includes an abutment 2241, a second elastic component 2242, and a limiting pin 2243. The cleaning frame 221 has receiving grooves 2211 that penetrate the upper and lower surfaces respectively. The abutment 2241 is located on the side of the second elastic component 2242 away from the bottom of the receiving groove 2211 and protrudes from the opening of the receiving groove 2211. The abutment 2241 has a waist-shaped hole 2244 that penetrates itself. The oblong hole 2244 extends vertically, and the limiting pin 2243 passes through the oblong hole 2244 and is fixed at both ends to the cleaning rack 221. Thus, after the abutment 2241 is pressed against the second elastic member 2242 by the cleaning belt, the abutment 2241 can move vertically relative to the limiting pin 2243 through the oblong hole 2244. Simultaneously, when outside the product 500, the abutment 2241 can move away from the bottom of the receiving groove 2211 under the action of the second elastic member 2242, without disengaging from the limiting pin 2243. Therefore, the second elastic member 224 can contract after entering the product 500 by resisting the inner wall of the product 500 with the cleaning belt, pressing the cleaning belt tightly against the inner wall of the product 500. After exiting the product 500, it can expand the cleaning belt again, exhibiting elasticity and facilitating cleaning.

[0029] It is understandable that the abutment member 2241 is made of a flexible material and its end face away from the second elastic member 2242 is a smooth curved surface. For example, as... Figure 6 As shown, in this embodiment, the abutment 2241 itself is also a flexible part, specifically made of rubber or silicone. The end face of the abutment 2241 away from the second elastic part 2242 is a smooth curved surface, that is, the end face in contact with the cleaning belt is a curved surface, which can further improve the elasticity of the contact and maximize the avoidance of pressure damage and impact to the product 500.

[0030] It is understood that a transfer platform 400 is also included, which is located between the positioning module 100 and the cleaning module 200 and is used to temporarily place the product 500. The positioning module 100 includes a first clamping part 101 and a second clamping part 102. The positioning module 100 is provided with a first driving mechanism 103. The output end of the first driving mechanism 103 is connected to the second clamping part 102 and is used to drive the second clamping part 102 to rotate. The movement paths of the first clamping part 101 and the second clamping part 102 both pass through the transfer platform 400. The cleaning module 200 is provided with two sets, namely a first cleaning module 201 and a second cleaning module 202. The first cleaning module 201 is used to clean the first opposing surface of the product 500 on the first clamping part 101, and the second cleaning module 202 is used to clean the second opposing surface of the product 500 on the second clamping part 102. For example, as Figures 1 to 3As shown, in this embodiment, a transfer platform 400 is provided between the positioning module 100 and the cleaning module 200. The positioning module 100 includes a first clamping part 101 and a second clamping part 102 located at the output end of the transplanting module. The cleaning module 200 also includes a first cleaning module 201 and a second cleaning module 202. When the first cleaning module 201 enters the product 500 held by the first clamping part 101 to clean the first opposing surface of the product 500, the product 500 with its first opposing surface cleaned is temporarily stored on the transfer platform 400. Then, the second clamping part 102 clamps the product 500 on the transfer platform 400, allowing the second cleaning module 202 to enter the product 500 held by the second clamping part 102 to clean the second opposing surface of the product 500. After being clamped by the second clamping part 102, the product 500 rotates under the drive of the first driving mechanism 103, facilitating the second cleaning module 202 to clean the second opposing surface of the product 500. Specifically, in this embodiment, the first driving mechanism 103 drives a 90-degree rotation, thus completing the cleaning of the entire inner surface of the cuboid product 500. Of course, if the product 500 is a polygonal prism, such as a triangular prism or a pentagonal prism, it can also be rotated by a corresponding angle to achieve cleaning of the inner surface of the product 500; or if the product 500 is cylindrical, multiple sets of clamping parts and corresponding cleaning modules 200 can be provided to achieve thorough cleaning of the inner surface of the product 500.

[0031] It should be understood that, in addition to configuring one of the first clamping part 101 and the second clamping part 102 to be rotatable, in other embodiments, the second cleaning module 202 can also be configured as a horizontally rotating cleaning belt. This eliminates the need to rotate the product 500; as long as the cleaning belt in the second cleaning module 202 is perpendicular to the cleaning belt in the first cleaning module 201, the entire inner surface of the cuboid product 500 can be cleaned. Alternatively, the second opposing surface inside the product 500 can be cleaned by driving the second cleaning module 202 to rotate while the product 500 remains stationary, i.e., by rotating the cleaning belt in the second cleaning module 202 by a certain angle.

[0032] It is understood that the conveying mechanism 210 is located on the side of the cleaning mechanism 220 away from the positioning module 100, and includes a feed roller 211 and a take-up roller 212. The feed roller 211 is used to unwind the cleaning tape, and the take-up roller 212 is used to wind the cleaning tape. For example, as Figures 1 to 3 , Figure 7As shown, in this embodiment, the conveying mechanism 210 is located on the side of the cleaning mechanism 220 away from the positioning module 100. It includes a feeding roller 211 for providing cleaning tape to the cleaning mechanism 220 and a receiving roller 212 for winding up the used cleaning tape. That is, in this embodiment, the cleaning tape is only partially fitted onto the cleaning frame 221. The cleaning tape continuously released by the feeding roller 211 is used to clean different products 500. In other words, a clean cleaning tape is used each time a new product 500 is cleaned, ensuring the cleaning effect.

[0033] It is understood that the cleaning mechanism 220 also includes a third elastic component 225 disposed at one end of the cleaning rack 221 near the conveying mechanism 210. The third elastic component 225 is used to abut against the bottom of the upper cleaning section and the upper part of the lower cleaning section. For example, as Figures 4 to 5 As shown, in this embodiment, the third elastic component 225 on the cleaning frame 221, which is located near the conveying mechanism 210 and away from the positioning module 100, can support the upper and lower parts of the end of the cleaning belt away from the roller assembly 222, thereby enabling the third elastic component 225 to work with the second elastic component 224 to provide elastic support for the upper and lower cleaning sections of the cleaning belt.

[0034] Understandably, it also includes a spray module 226, which is positioned towards the cleaning belt and used to spray cleaning fluid onto the cleaning belt. For example, as Figure 2 As shown, in this embodiment, a cleaning solution is sprayed onto the cleaning belt via a spray assembly, allowing the moistened cleaning belt to better clean dust and oil stains from the inner surface of the product 500. Specifically, the cleaning solution can be a solution such as alcohol that can clean oil stains and dust.

[0035] It is understood that the positioning module includes a second drive mechanism 104 and a third drive mechanism 105. The output end of the second drive mechanism 104 is connected to the clamping end and is used to drive the clamping end to move horizontally closer to or further away from the transfer table 400. The output end of the third drive mechanism 105 is connected to the clamping end and is used to drive the clamping end to move up and down. For example, as... Figures 2 to 3 As shown, in this embodiment, the second drive mechanism 104 can drive the clamping end to move horizontally, and the third drive mechanism 105 can drive the clamping end to rise and fall, thereby realizing the transfer of the product 500 on the transfer table 400.

[0036] It is understood that the conveying mechanism 210 includes a conveying assembly 213, which is disposed between the feed roller 211 and the cleaning mechanism 220 and is used to move the cleaning belt. For example, as Figures 7 to 8As shown, in this embodiment, the conveying mechanism 210 includes a conveying assembly 213 disposed between the unloading roller 211 and the cleaning mechanism 220, which enables the movement of the cleaning belt. Specifically, the conveying assembly 213 includes a drive roller 2131, a first driven roller 2132 located above the drive roller 2131, and a second driven roller 2133 located below the drive roller 2131. The first driven roller 2132 is used to cooperate with the drive roller 2131 to deliver the unwound cleaning belt, and the second driven roller 2133 is used to cooperate with the drive roller 2131 to deliver the cleaning belt to be rewound.

[0037] It should be understood that the upper and lower parts of the third elastic component 225 are respectively provided with the first guide roller component 227, thereby enabling the limiting of the upper part of the cleaning section and the lower part of the cleaning section on the cleaning belt.

[0038] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
