[0001] This utility model relates to the field of product processing technology, specifically to a conveying component and a cleaning device. Background Technology

[0002] With the advancement of technology, mobile phones, tablets and other electronic products have become indispensable tools in life. The pace of electronic product updates and iterations is accelerating, and consumers' demand for innovation in electronic products is increasing. Glass window covers have become widespread. With technological innovation and progress, and consumers' pursuit of novelty, the 3D product design of the glass back cover features a rectangular protrusion running through the entire short side, making the front of the entire shell a groove and the back a protrusion. The groove can be more than 3mm deep.

[0003] After the initial processing of the electronic product casing is completed, it will be cleaned. During the cleaning process, the conveyor roller and pressure roller in the existing cleaning station work together to drive the electronic product casing to be transported along the conveying direction. Because the length of the conveyor roller is insufficient to support the groove, and the roller surface of the pressure roller cannot deform to apply rigid pressure to the boss, the electronic product casing shakes or gets stuck during the transport process, which affects the smooth transport of the electronic product casing.

[0004] In summary, there is an urgent need to develop a conveying component and cleaning device that can effectively solve the above-mentioned technical problems. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] The following is combined with Figures 1 to 11 The following describes embodiments of the present invention.

[0023] According to an embodiment of the present invention, in one aspect, a conveying assembly 11 is provided for conveying a product having a boss on one side and a groove on the other side, comprising: The conveying assembly 11 includes several sets of first conveying roller groups 1101. Each set of first conveying roller groups 1101 includes a flexible pressure roller 11011 and a first conveying roller 11012 arranged opposite to each other. A first passageway 11013 is formed between the flexible pressure roller 11011 and the first conveying roller 11012. The several sets of first conveying roller groups 1101 are arranged along the conveying direction to form a first conveying channel. The axial dimension of the first conveying roller 11012 is larger than the dimension of the groove of the product to be conveyed. The flexible pressure roller 11011 and the first conveying roller 11012 cooperate to allow the product to be conveyed to pass smoothly through the first passageway 11013 and remain on the conveying path of the first conveying channel.

[0024] In this embodiment, as Figure 4 , Figure 5 As shown, in the first conveying roller group 1101, the flexible pressure roller 11011 is at the top and the first conveying roller 11012 is at the bottom. The roller surface of the first conveying roller 11012 is in contact with the groove surface of the product to be conveyed, and the flexible pressure roller 11011 is in contact with the boss surface of the product to be conveyed. At this time, the product to be conveyed is in a state where the boss is facing up and the groove is facing down.

[0025] In this technical solution, a first conveying channel is formed by several first conveying roller groups 1101 along the conveying direction, allowing the product to be conveyed to move along the first conveying channel. The axial dimension of the first conveying roller 11012 is larger than the groove size of the product to be conveyed. During operation, the first conveying roller 11012 contacts the outer surface of the groove of the product to be conveyed, without extending into the groove or obstructing the transport of the product. At the same time, a flexible pressure roller 11011 contacts the protrusion surface of the product to be conveyed with flexible pressure, which does not cause strong obstruction to the protrusion and prevents the product to be conveyed from getting stuck or shaking in the first conveying channel. This allows the product to be conveyed to pass smoothly through the first passageway 11013 and remain on the path of the first conveying channel, ensuring the smooth transport of the product.

[0026] In one embodiment, such as Figure 4 , Figure 5 and Figure 6 As shown, a guide support 11023 is fitted at a preset position on the outer periphery of the first conveying roller 11012, and the guide support 11023 is detachably connected to the first conveying roller 11012. The product to be conveyed has a step formed by the protrusion. When the product is transported with the protrusion facing down and the groove facing up, this configuration allows for the connection of the guide support 11023 to the first conveying roller 11012 to form a second conveying roller 11021, enabling switching between the first and second conveying rollers 11012 and improving their versatility. The roller surface of the first conveying roller 11012 supports the protrusion, and the guide support 11023 provides support for the step portion of the product with the protrusion, ensuring that the product is subjected to overall force on the side with the protrusion, which is beneficial for product transport. In this embodiment, the connection between the first conveying roller 11012 and the guide support 11023 is not specifically limited. The two can be detachably connected by various methods such as snap-fit, bolt connection, or plug-in connection. Those skilled in the art should understand that the dimensions of the guide support 11023 match the height of the boss.

[0027] In one embodiment, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the conveying assembly 11 also includes several sets of second conveying roller groups 1102. Each second conveying roller group 1102 includes a flexible pressure roller 11011 and a second conveying roller 11021 arranged opposite each other. A guide support 11023 is sleeved at a predetermined position on the outer periphery of the roller surface of the second conveying roller 11021. In this embodiment, two guide support members 11023 are sleeved on the roller surface of the second conveying roller 11021. The two guide support members 11023 are spaced apart, and the distance between the guide inner walls 110231 of the two guide support members 11023 is sufficient to accommodate the width of the boss. Figure 6 In the Y direction, that is, the inner guide wall 110231 of the two guide supports 11023 is fitted against the outer wall of the boss. With this configuration, the guide support 11023 can effectively act as a stop to prevent the product to be conveyed from deviating.

[0028] In this state, such as Figure 4 , Figure 5As shown, in the second conveying roller group 1102, the flexible pressure roller 11011 is above and the second conveying roller 11021 is below. The side wall of the guide support member 11023 of the second conveying roller 11021 is in contact with the outer side wall of the boss of the product to be conveyed. The two guide support members 11023 provide support and guidance for the product to be conveyed. The flexible pressure roller 11011 is in contact with the groove surface of the product to be conveyed. At this time, the product to be conveyed is in a state with the groove facing up and the boss facing down.

[0029] In one embodiment, such as Figure 4 , Figure 5 As shown, several sets of second conveyor rollers 1102 are arranged along the conveying direction to form a second conveying channel, and the first conveying channel is arranged parallel to the second conveying channel. Figure 4 As shown, there are two sets of first conveying roller groups 1101 to form two first conveying channels, and two sets of second conveying roller groups 1102 to form two second conveying channels. The two first conveying channels and the two second conveying channels are arranged side by side. The flexible pressure rollers 11011 of the first conveying roller group 1101 and the flexible pressure rollers 11011 of the second conveying roller group 1102 are driven by the same upper rotating shaft. The first conveying roller 11012 of the first conveying roller group 1101 and the second conveying roller 11021 of the second conveying roller group 1102 are driven by the same lower rotating shaft. The rotation speeds of the upper rotating shaft and the lower rotating shaft are the same.

[0030] In one embodiment, the flexible pressure roller 11011 is a brush pressure roller, that is, the roller surface of the flexible pressure roller 11011 is provided with bristles to provide flexible pressure, and can also prevent the products to be conveyed from rushing forward and causing stacking, card scratches, etc., to ensure smooth and stable transmission.

[0031] According to an embodiment of the present invention, another aspect, a cleaning device is also provided, such as... Figure 1 , Figure 2 As shown, the system includes a cleaning station 1, a cleaning assembly 12, and the aforementioned conveying assembly 11. The cleaning assembly 12 is disposed within the accommodating space of the cleaning station 1, and can clean the conveyed products on the conveying assembly 11. By providing the conveying assembly 11 and the cleaning assembly 12 within the cleaning station 1, the transportation and cleaning of the products to be conveyed are achieved.

[0032] In one embodiment, such as Figure 2 , Figure 11 As shown, the cleaning assembly 12 includes a first cleaning roller group 1201, which is disposed on the first conveying channel. The first cleaning roller group 1201 includes a first upper brush cleaning roller and a first lower brush cleaning roller. The bristles of the first upper brush cleaning roller and the first lower brush cleaning roller are inclined relative to the roller surface. The inclined arrangement allows the bristles to clean the outer wall of the boss or the inner wall of the groove, thereby improving the cleaning ability.

[0033] In one embodiment, such as Figure 2 , Figure 11 As shown, the cleaning assembly 12 further includes a second cleaning roller group 1202 and a third cleaning roller group 1203. The second cleaning roller group 1202 includes a second upper brush cleaning roller and a second lower brush cleaning roller. The bristles of the second upper brush cleaning roller and the second lower brush cleaning roller are inclined relative to the roller surface. The inclination direction of the bristles of the first upper brush cleaning roller is opposite to that of the second upper brush cleaning roller, and the inclination direction of the bristles of the first lower brush cleaning roller is opposite to that of the second lower brush cleaning roller. The third cleaning roller group 1203 includes a third upper brush cleaning roller and a third lower brush cleaning roller. The bristles of the third upper brush cleaning roller and the third lower brush cleaning roller are vertically arranged. The third cleaning roller group 1203 cleans the surface of the boss or the inner surface of the groove. It should be noted that this application does not limit the tilting direction of the first upper brush cleaning roller and the first lower brush cleaning roller; they can clean sidewalls in the same direction or in different directions. Similarly, it does not limit the tilting direction of the second upper brush cleaning roller and the second lower brush cleaning roller; they can clean sidewalls in the same direction or in different directions. By configuring the first cleaning roller group, the second cleaning roller group, and the third cleaning roller group, the surface of the product to be conveyed, the inner sidewalls of the groove, and the outer sidewalls of the boss can be effectively cleaned.

[0034] Compared to straight brushes that can only reach the surface area of ​​the product to be conveyed, this application uses a staggered tilting arrangement, where the bristles of the first upper brush cleaning roller are tilted in the opposite direction to those of the second upper brush cleaning roller, and the bristles of the first lower brush cleaning roller are tilted in the opposite direction to those of the second lower brush cleaning roller. This allows for effective brushing of the inner sidewalls of the groove and the outer sidewalls of the boss (and can also clean the through holes if the product to be conveyed has them), thus significantly improving cleaning capabilities.

[0035] In this embodiment, the number of cleaning stations 1 is not specifically limited. Preferably, there are 6 cleaning stations 1, each with identical configurations. Adjacent cleaning stations 1 have their first conveying channels connected to each other, and their second conveying channels connected to each other. Multiple sets of cleaning components 12 can be configured within one cleaning station 1. For example... Figure 2 The cleaning station 1 is also equipped with a spray head 13, which sprays cleaning liquid or clean water toward the product to be transported.

[0036] In one embodiment, such as Figure 1 , Figure 3 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the cleaning device also includes a drying table 2, which is located at the rear of the cleaning table 1. The drying table 2 has an air knife chamber, and the air knife chamber has an air outlet 2106. The shape of the air outlet 2106 is a continuous curved segment, and the vertical distance between the highest and lowest points of the air outlet 2106 is greater than the depth of the groove or the thickness of the boss. In this embodiment, as... Figure 3 As shown, the air knife chamber includes an upper air knife chamber 21 and a lower air knife chamber 22. The air outlet 2106 of the upper air knife chamber 21 is arranged downwards, and the air outlet 2106 of the lower air knife chamber 22 is arranged upwards, so as to blow air onto the surface of the product to be conveyed. The vertical distance between the highest point and the lowest point of the air outlet 2106 is ( Figure 10 In the Z direction), greater than the depth of the groove ( Figure 10 (in the X direction) or the thickness of the boss ( Figure 10 In the Z direction, compared to the straight air outlet 2106 blowing directly onto the boss (or groove), which causes the product to be transported to be subjected to greater air pressure and thus obstructs the transmission (because the straight air outlet 2106 will concentrate the air on a certain straight line of the product to be transported, and with the groove or boss setting of the product to be transported, warping and obstruction are easy to occur during the transport process), the continuous curved section of the air outlet 2106 of this application makes the transmission smoother and avoids the problem of product warping and obstruction due to greater air pressure.

[0037] In one embodiment, such as Figure 1 , Figure 3 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the air knife chamber includes an air inlet pipe 2104, a first air knife housing 2101, and a second air knife housing 2102. The first air knife housing 2101 and the second air knife housing 2102 form a through-flow uniform air channel 2103 and an air outlet 2106. The air outlet end 21041 of the air inlet pipe 2104 is located within the uniform air channel 2103. The pipe wall of the air outlet end 21041 is provided with a plurality of air outlet holes 21042, which are connected to the air outlet 2106. The air from the air outlet 2106 is evenly distributed through the uniform air channel 2103 before reaching the air outlet 2106. In this embodiment, the upper air knife chamber 21 and the lower air knife chamber 22 respectively include an air inlet pipe 2104, a first air knife housing 2101, and a second air knife housing 2102. A uniform airflow channel 2103 is formed by the inner walls of the first air knife housing 2101 and the second air knife housing 2102. The outer peripheral wall of the air inlet end has gaps with the inner walls of the first air knife housing 2101 and the second air knife housing 2102, respectively, so that the air blown out through the air outlet 21042 is evenly distributed through the uniform airflow channel 2103 and reaches the air outlet 2106, from which it is blown out. In this embodiment, as... Figure 7 , Figure 9and Figure 10 As shown, by setting continuous curved segments, water stains on the surface of the product to be transported are driven out from the middle to the edge, which enhances the purging efficiency. After purging, the surface of the product to be transported is cleaner, which improves the water stains left at the very end of the product after the traditional straight air knife purging.

[0038] In this embodiment, as Figure 1 , Figure 3 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the first air knife housing 2101 and the second air knife housing 2102 are made of aluminum alloy. Both the first air knife housing 2101 and the second air knife housing 2102 have hollow, irregular cavities inside, with the internal cavity of the first air knife housing 2101 being larger than that of the second air knife housing 2102. This ensures that the air velocity at the outlet 2106 is uniformly swept out and enhanced. Furthermore, this embodiment does not specifically limit the number of air knife cavities. The distance between the upper air knife cavity 21 and the lower air cavity can be adjusted using a linear lifting module to accommodate different products to be conveyed.

[0039] In the specific implementation process, the product to be conveyed moves along the first conveying channel (protrusion facing up, groove facing down) or the second conveying channel (protrusion facing down, groove facing up). The spray head 13 sprays out cleaning liquid or clean water, and the cleaning component 12 cleans the product to be conveyed. After the cleaning is completed, the product to be conveyed enters the drying table 2 and is dried by the air knife chamber of the drying table 2.

[0040] In another embodiment of this utility model, the first conveying channel is located upstream or downstream of the second conveying channel, that is, the first conveying channel and the second conveying channel are connected. Between the first conveying channel and the second conveying channel, a reversing robotic arm is provided in the cleaning table 1. The robotic arm grabs the product to be conveyed and rotates it 180°.

[0041] As an alternative implementation, the number of guide supports 11023 sleeved on the roller surface of the second conveying roller 11021 is three, four, five or even more.

[0042] As an alternative implementation, the shape of the air outlet 2106 is a continuous broken line segment and / or a curved segment. That is, the air outlet 2106 can also be a continuous broken line segment, or the shape of the air outlet 2106 can also be a mixture of broken line segments and curved segments.

[0043] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
