Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, specifically to a follow-up automatic cleaning device and system for automotive decorative parts. Background Technology

[0002] The complexity of multiple processes in the production of automotive trim parts makes their surfaces highly susceptible to the accumulation of dust, impurities, and other tiny particles. While these minor imperfections are difficult to detect, they have a significant impact on the quality of the final product. To ensure that trim parts meet high-quality standards, cleaning is an indispensable and crucial step. Professional cleaning processes can precisely remove surface impurities, leaving the product surface sparkling clean. This lays a solid foundation for subsequent assembly and use, thereby guaranteeing the aesthetics and durability of the vehicle's interior trim.

[0003] For some small and medium-sized enterprises, manual cleaning is generally used, which is inefficient. To address this, most automotive trim production lines are now equipped with cleaning lines to automate the cleaning process. Specifically, trim parts are typically conveyed to a cleaning station and then stopped, where a cleaning mechanism operates. The trim parts are then conveyed again, and the cleaning mechanism cleans the next trim part, thus cleaning each trim part on the production line one by one. However, this cleaning method requires the cleaning mechanism to coordinate with the stopping of the conveyor line. This intermittent cleaning method places high demands on the stability of the production cycle. If the cleaning time does not match the conveyor cycle, trim parts may accumulate, affecting the smoothness of the entire production process and the stability of product quality. Moreover, frequent starts and stops reduce the overall operating efficiency of the production line. Summary of the Invention

[0004] The purpose of this invention is to provide a follow-up automatic cleaning device and cleaning system for automotive trim parts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automatic cleaning device for automotive trim parts includes a base and a horizontal plate fixed on the base. The base is provided with a conveyor line for the trim parts, and the conveyor line includes a detour section arranged in a semi-circle. Also includes: The transmission component is mounted on the horizontal plate. The two ends of the transmission component are respectively formed with a first detour section and a second detour section in a semi-circular shape. The second detour section is concentric with the detour section. The transmission component is provided with multiple covers. Each of the multiple covers is connected to the transmission component through a set of height switching mechanisms. A cleaning mechanism is provided in the cover. When the transmission component moves, the cover located above the detour section can move down to cover the decorative part, and the transmission component drives the cover to move along the detour section, so that the cover and the decorative part remain relatively stationary. The cleaning mechanism blows and brushes the decorative part in turn, and a vacuum cleaner is installed on the side of the base near the detour section.

[0006] As a further aspect of the present invention: the height switching mechanism includes a telescopic structure disposed between the transmission member and the cover, and a limiting component cooperating with the telescopic structure. The telescopic structure includes a guide plate fixedly connected to the transmission member and a sleeve plate fixed to the cover. The guide plate and the sleeve plate are slidably fitted together, and an elastic connecting member is provided between them.

[0007] As a further embodiment of the present invention: the guide plate is provided with a cylindrical cavity, and the elastic connector includes a column fixed inside the sleeve and extending into the cylindrical cavity. The column is slidably connected to the guide plate. The cylindrical cavity is also provided with a spring sleeved on the outer periphery of the column. One end of the spring is connected to the inner bottom wall of the cylindrical cavity, and the other end is connected to a frustum fixed at the end of the column away from the cover.

[0008] As a further embodiment of the present invention: two drive wheels corresponding to the first detour section and the second detour section are rotatably mounted on the horizontal plate, and a first motor is also mounted on the horizontal plate. The output end of the first motor is connected to the rotation shaft of one of the drive wheels. The transmission component connects the two drive wheels and rolls with the two drive wheels. The limiting component includes a limiting member fixed to the horizontal plate. The two ends of the limiting member are respectively formed with semicircular portions. The two semicircular portions are concentric with the first detour portion and the second detour portion, respectively. The side of the sleeve plate is provided with a roller, and the roller abuts against the bottom of the limiting member.

[0009] As a further embodiment of the present invention: the bottom of the limiting member is provided with a "U"-shaped protrusion on the side near the detour section, and the end of the "U"-shaped protrusion is connected and transitioned to the side of the bottom of the limiting member away from the detour section by an inclined surface.

[0010] As a further embodiment of the present invention: the cleaning mechanism includes an air blower and a brush movably disposed within the housing, the air blower and the brush being driven by a power mechanism disposed within the housing to perform circular motion, the air blower being connected to an air supply structure, and the brush being driven by an electric mechanism disposed within the housing to deflect relative to the power mechanism.

[0011] As a further embodiment of the present invention: an assembly plate is slidably provided inside the cover, and two first electric push rods are fixed on the cover. The movable ends of the first electric push rods are fixed to the assembly plate. The power mechanism includes a vertical pipe rotatably mounted on the assembly plate and a second motor mounted on the assembly plate and whose output end is connected to the vertical pipe. The riser is rotatably mounted with a horizontal shaft perpendicular to the riser at the end away from the second motor. The brush is fixed to the end of the horizontal shaft away from the riser. The horizontal shaft is connected to the electric mechanism. The riser is fixedly connected with a guide tube. The air blowing head is fixed to the end of the guide tube away from the riser.

[0012] As a further embodiment of the present invention: the air supply structure includes an air inlet pipe fixed to the mounting plate and a kit fixedly connected to the air inlet pipe. The kit is rotatably and sealed to the riser, and the riser is also provided with a plurality of openings equidistant from each other along the circumference and enclosed by the kit.

[0013] As a further embodiment of the present invention: the electric mechanism includes a second electric push rod fixedly mounted on the assembly plate and a horizontal arm fixed to the movable end of the second electric push rod. The end of the horizontal arm away from the second electric push rod is rotatably connected to a first sleeve slidably sleeved on the riser. The first sleeve is connected to a second sleeve slidably sleeved on the horizontal shaft via a connecting rod. The connecting rod is hinged to the first sleeve and the second sleeve at both ends, respectively. The outer wall of the horizontal shaft is provided with a spiral groove. A column extending into the groove and slidably connected to the horizontal shaft is fixed on the second sleeve.

[0014] A car trim cleaning system includes the aforementioned follow-up automatic cleaning device.

[0015] Compared with the prior art, the beneficial effects of the present invention are: By setting a conveyor line with a semi-circular detour section on the base, and setting a transmission component above the conveyor line, the second detour section on the transmission component is concentric with the detour section, so that the running speed of the transmission component and the conveyor line are kept synchronized. Specifically, during operation, the transmission component can drive multiple covers to move. Before the cover reaches the starting point of the detour section, the height switching mechanism can cause the cover to move down to cover the decorative part and prevent dust generated during the cleaning process from escaping. Then, the cover and the decorative part remain relatively stationary as they pass through the detour section. During this period, the cleaning mechanism inside the cover successively blows and brushes the decorative part. After the cover passes through the detour section, the height switching mechanism drives the cover to rise again, so that the cleaned decorative part is conveyed toward the next process. Therefore, by setting up a conveyor line and transmission components with the common feature of a semi-circular structure, and using a height switching mechanism to drive the cover to change height at specific times, the cleaning mechanism performs cleaning work while the cover and decorative parts remain relatively stationary. This achieves uninterrupted follow-up cleaning of the decorative parts without the need for frequent start-stop operations, thereby improving the overall operating efficiency of the production line. Moreover, it helps to maintain a stable production rhythm, avoids the accumulation of decorative parts, and ensures the smoothness of the entire production process and the stability of product quality.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0029] Please see Figures 1-10 In this embodiment of the invention, an automatic cleaning device for automotive trim parts includes a base 1 and a horizontal plate 3 fixedly disposed above the base 1. The base 1 is provided with a conveyor line 4 for the trim parts, and the conveyor line 4 includes a semi-circular detour section 401. Also includes: The transmission component 8 is located below the horizontal plate 3. The two ends of the transmission component 8 are respectively formed with a first detour section 801 and a second detour section 802 in a semi-circular shape. The second detour section 802 is concentric with the detour section 401. Multiple covers 10 are evenly provided on the transmission component 8. Each of the multiple covers 10 is connected to the transmission component 8 through a set of height switching mechanisms. A cleaning mechanism is provided in the cover 10. When the transmission component 8 moves, the cover 10 located above the detour section 401 can move down to cover the decorative part, and the transmission component 8 drives the cover 10 to move along the detour section 401, so that the cover 10 and the decorative part remain relatively stationary. The cleaning mechanism sprays and brushes the decorative part in turn, and a vacuum cleaner 2 is installed on the side of the base 1 near the detour section 401.

[0030] It should be noted that the conveyor line 4 is an application of existing technology. In this application, only part of its shape is described, and its specific structure and principle will not be described in detail. Secondly, similar to existing methods, multiple fixed posts 5 are evenly arranged on the conveyor line 4. During the operation of the production line, the fixed posts 5 serve as carriers for the decorative parts, which are located on the fixed posts 5. The conveyor line 4 drives the decorative parts through various processing steps. The distance between each fixed post 5 is equal, and the distance between each cover 10 is also equal. Moreover, the distance between two adjacent cover 10s is equal to the distance between two adjacent fixed posts 5s. In this way, when the transmission member 8 moves, each cover 10 moves down in sequence, thus covering the decorative parts on each fixed post 5 in sequence.

[0031] Specifically, during processing, the conveyor line 4 and the transmission component 8 operate at synchronized speeds. Before the cover 10 reaches the starting point of the detour section 401, the height switching mechanism is triggered, causing the cover 10 to move downwards. Thus, the cover 10 covers the decorative part. Subsequently, the transmission component 8 drives the cover 10 to move along the detour section 401, and the cover 10 and the decorative part remain relatively stationary. During this period, the cleaning mechanism operates, successively spraying and brushing the decorative part. Therefore, some of the dust on the decorative parts can be blown away, while some stubborn dust (that is, dust that is difficult to remove by blowing) is brushed off, thus achieving an effective cleaning function for the decorative parts and ensuring the final quality of the decorative parts. It should be noted that whenever the cover 10 moves down, there will be a certain gap between the bottom of the cover 10 and the surface of the base 1. During operation, the vacuum cleaner 2 remains running and can collect the dust blown off the decorative parts and the dust brushed off, so as to avoid dust pollution of the working environment or secondary pollution of the decorative parts that have been cleaned.

[0032] This application provides a conveyor line 4 with a semi-circular detour section 401 on the base 1, and a transmission member 8 is provided above the conveyor line 4. The second detour section 802 on the transmission member 8 is concentric with the detour section 401 and has the same radius, so that the running speed of the transmission member 8 and the conveyor line 4 are kept synchronized. During operation, the transmission member 8 can drive multiple covers 10 to move. Before the cover 10 reaches the starting point of the detour section 401, the height switching mechanism can cause the cover 10 to move down to cover the decorative part and prevent dust generated during the cleaning process from escaping. Then the cover 10 and the decorative part remain relatively stationary and pass through the detour section 401. During this period, the cleaning mechanism inside the cover 10 successively completes the spraying and brushing treatment of the decorative part. After the cover 10 passes through the detour section 401, the height switching mechanism drives the cover 10 to rise again, so that the cleaned decorative part is conveyed towards the next process. Therefore, by setting up a conveyor line 4 and a transmission component 8 with the common feature of a semi-circular structure, and using a height switching mechanism to drive the cover 10 to change height at a specific time, the cleaning mechanism performs cleaning work while the cover 10 and the decorative parts remain relatively stationary. This achieves uninterrupted follow-up cleaning of the decorative parts without the need for frequent start-stop operations, thereby improving the overall operating efficiency of the production line. Moreover, it helps to maintain a stable production rhythm, avoids the accumulation of decorative parts, and ensures the smoothness of the entire production process and the stability of product quality.

[0033] Please refer to it again. Figure 8 and Figure 9 The height switching mechanism includes a telescopic structure disposed between the transmission member 8 and the cover 10, and a limiting component cooperating with the telescopic structure. The telescopic structure includes a guide plate 11 fixedly connected to the bottom of the transmission member 8 and a sleeve plate 12 fixedly on the cover 10. The guide plate 11 and the sleeve plate 12 are slidably fitted together, and an elastic connecting member is provided between them. The guide plate 11 has a cylindrical cavity. The elastic connecting member includes a column 13 fixed to the bottom of the sleeve plate 12 and extending into the cylindrical cavity. The column 13 is slidably connected to the guide plate 11. A spring 14 is also provided in the cylindrical cavity and sleeved on the outer periphery of the column 13. One end of the spring 14 is connected to the inner bottom wall of the cylindrical cavity, and the other end is connected to a frustum 1301 fixedly disposed at the end of the column 13 away from the cover 10.

[0034] Please refer to it again. Figure 7Two drive wheels 7, corresponding to the first detour section 801 and the second detour section 802 respectively, are rotatably mounted on the horizontal plate 3. A first motor 6 is also mounted on the horizontal plate 3. The output end of the first motor 6 is connected to the rotation shaft of one of the drive wheels 7. The transmission component 8 connects the two drive wheels 7 and rolls with them. The limiting component includes a limiting member 9 fixed on the horizontal plate 3. The two ends of the limiting member 9 are respectively formed with semicircular portions. The two semicircular portions are concentric with the first detour section 801 and the second detour section 802 respectively. A roller 1201 is provided on the side of the sleeve plate 12. The outer circumference of the rim of the roller 1201 abuts against the bottom of the limiting member 9.

[0035] Please refer to it again. Figure 5 and Figure 7 The bottom of the limiting member 9 is provided with a "U"-shaped protrusion 901 on the side near the detour section 401. The end of the "U"-shaped protrusion 901 is connected and transitioned to the side of the bottom of the limiting member 9 away from the detour section 401 through the inclined surface 902.

[0036] During operation, the first motor 6 operates, driving the drive wheel 7 to rotate. As a result, the transmission component 8 can operate continuously, causing the multiple covers 10 to move along the shape trajectory of the transmission component 8. That is, when the cover 10 moves above the detour section 401, its movement trajectory can be consistent with the detour section 401, so as to ensure that the cover 10 and the decorative parts located on the detour section 401 remain relatively stationary, providing sufficient time for the cleaning mechanism to work. Furthermore, during the operation of the transmission component 8, the roller 1201 rolls along the bottom of the limiting component 9. When the roller 1201 contacts the inclined surface 902, it will give way. Correspondingly, the roller 1201 drives the sleeve 12 to slide downward relative to the guide plate 11, the cover 10 moves downward, the spring 14 is compressed, and then the roller 1201 rolls onto the inclined surface 902 at one end of the "U"-shaped protrusion 901, and the cover 10 covers the decorative parts below it. As the roller 1201 rolls along the "U"-shaped protrusion 901, the cleaning mechanism successively blows and brushes the decorative parts. Afterward, the roller 1201 rolls onto the inclined surface 902 at the other end of the "U"-shaped protrusion 901. During this process, the spring 14 rebounds, which can reset all components. That is, the sleeve plate 12 slides upward relative to the guide plate 11, and the cover 10 is lifted and reset, so that the decorative parts that have been cleaned are exposed again and continue to be conveyed to the next process.

[0037] Please refer to it again. Figure 8 , Figure 9 as well as Figure 10The cleaning mechanism includes an air blower 22 and a brush 24 movably disposed within the cover 10. The air blower 22 and the brush 24 can be driven by a power mechanism disposed within the cover 10 to perform circular motion. The air blower 22 is connected to an air supply structure, and the brush 24 can be driven by an electric mechanism disposed within the cover 10 to oscillate relative to the power mechanism. An assembly plate 16 is slidably disposed inside the cover 10. Two first electric push rods 15 are also fixed on the cover 10. The movable end of the first electric push rod 15 is fixed to the assembly plate 16. The power mechanism includes a riser 18 rotatably mounted on the assembly plate 16 and a second motor 17 mounted on the assembly plate 16 and whose output end is connected to the riser 18. A horizontal shaft 23 perpendicular to the riser 18 is rotatably mounted at the end of the riser 18 away from the second motor 17. The brush 24 is fixed to the end of the horizontal shaft 23 away from the riser 18. The horizontal shaft 23 is connected to the electric mechanism. A guide tube 21 is fixedly connected to the riser 18. The air blowing head 22 is fixed to the end of the guide tube 21 away from the riser 18. The air supply structure includes an air inlet pipe 20 fixed on the assembly plate 16 and a kit 19 fixedly connected to the air inlet pipe 20. The kit 19 is sealed and rotatably connected to the riser pipe 18, and the riser pipe 18 is also provided with a plurality of openings 1801 equidistantly along the circumference and enclosed by the kit 19.

[0038] During operation, when the roller 1201 rolls over the inclined plane 902 onto the "U"-shaped protrusion 901, the cover 10 covers the decorative part. At this time, the brush 24 does not contact the groove on the decorative part. The second motor 17 operates, driving the air blower 22 and the brush 24 to perform circular motion through the riser 18. An external air pump blows air, which passes through the air inlet 20, the kit 19, the port 1801, the riser 18, the guide tube 21, and the air blower 22 in sequence and blows into the groove of the decorative part, so that some dust can be blown away. Subsequently, the first electric push rod 15 drives the mounting plate 16 to slide downward until the brush 24 enters the groove of the decorative part. Thus, the brush 24 performs circular motion, which can clean stubborn dust. Furthermore, the brush 24 and the horizontal shaft 23 are detachably connected. When maintaining the device, the first electric push rod 15 drives the mounting plate 16 to slide downward inside the cover 10 until the brush 24 is exposed outside the cover 10, which makes it convenient for staff to inspect or replace the brush 24.

[0039] The electric mechanism further includes a second electric push rod 25 fixedly mounted on the assembly plate 16 and a cross arm 26 fixed to the movable end of the second electric push rod 25. The end of the cross arm 26 away from the second electric push rod 25 is rotatably connected to a first sleeve 27 slidably sleeved on the riser 18. The first sleeve 27 is connected to a second sleeve 29 slidably sleeved on the horizontal shaft 23 via a connecting rod 28. The two ends of the connecting rod 28 are respectively hinged to the first sleeve 27 and the second sleeve 29. The outer wall of the horizontal shaft 23 is provided with a spirally arranged sliding groove 2301. A column 2901 is fixed on the second sleeve 29, extending into the sliding groove 2301 and slidably connected to the horizontal shaft 23.

[0040] With attachment Figure 8 Taking the illustrated state as an example, the brush 24 is in an inclined state. After the brush 24 moves around the groove on the decorative part more than one revolution, the second electric push rod 25 operates, driving the horizontal arm 26 to move downward. Correspondingly, the horizontal arm 26 drives the first sleeve 27 to slide downward on the vertical tube 18, and the first sleeve 27 pushes the second sleeve 29 to slide towards the brush 24 on the horizontal axis 23 through the connecting rod 28. During this process, the column 2901 slides with the horizontal axis 23 through the sliding groove 2301, causing the horizontal axis 23 to rotate. Thus, the horizontal axis 23 drives the brush 24 to deflect relative to the vertical tube 18. During the deflection of the brush 24, it sweeps the dust in the groove of the decorative part upward, which can promote the discharge of dust in the groove of the decorative part, thereby achieving deep cleaning of the inside of the groove of the decorative part. This design, by utilizing the physical characteristics and shape changes of the brush 24, makes the cleaning process more efficient and thorough, ensuring the quality stability of the decorative part in subsequent processes. Furthermore, during the subsequent assembly of decorative parts, the grooves on the decorative parts are generally sealed to other components. In this regard, the grooves on the decorative parts can be effectively cleaned to ensure that the connection between the decorative parts and other components is tight and reliable, thereby ensuring the overall assembly quality and sealing performance.

[0041] As another embodiment of the present invention, an automotive trim cleaning system is also proposed, including the aforementioned follow-up automatic cleaning device.
