Description

Technical Field

[0001] This application relates to the field of product cutting and separation technology, and in particular to a cutting and conveying device. Background Technology

[0002] With the rapid development of 3C electronic products, especially the rapid development of production technology, glass panels, with their transparent and smooth sensory characteristics, are widely used in the display devices of 3C electronic products. For example, glass panels are used in the screens of electronic products such as mobile phones, smartwatches, in-vehicle displays and monitors to protect the screens of these products from scratches.

[0003] In the glass panel production process, large glass panels need to be cut into multiple small glass pieces. However, the gap between two adjacent glass pieces after cutting is very small, which makes it difficult for the robotic arm to grasp the cut glass pieces that are being transported at high speed on the conveyor line in subsequent processes. This can easily damage adjacent glass pieces after cutting. Utility Model Content

[0004] Therefore, it is necessary to provide a cutting and conveying device to address the problem that the small gap between two adjacent glass sheets after cutting makes it difficult for the robot to grasp the glass sheets and easily damages them. This device can increase the gap between two adjacent glass sheets after cutting on the conveying line, making it easier for the robot to grasp them.

[0005] According to one aspect of this application, a cutting and conveying device is provided, comprising:

[0006] A cutting mechanism, the cutting mechanism including a frame and a cutter movably mounted on the frame;

[0007] A first conveying mechanism is provided through the frame along a conveying direction, such that the cutter is positioned above the first conveying mechanism. The first conveying mechanism is used to convey products along the conveying direction at a first conveying speed V1.

[0008] A second conveying mechanism is disposed adjacent to the first conveying mechanism in the conveying direction. The second conveying mechanism is used to convey the product along the conveying direction at a second conveying speed V2, which is greater than the first conveying speed V1.

[0009] In one embodiment, the difference ΔV between the second conveying speed V2 and the first conveying speed V1 is ≤250mm.

[0010] In one embodiment, the first conveying mechanism is set at a higher height than the second conveying mechanism, so that there is a height difference ΔH between the first conveying mechanism and the second conveying mechanism.

[0011] In one embodiment, the height difference ΔH ≤ 150 mm.

[0012] In one embodiment, the first conveying mechanism has an output end near the second conveying mechanism, the second conveying mechanism has an input end near the first conveying mechanism, the output end and the input end are arranged adjacent to each other in the conveying direction, and the output end is located above the input end in the vertical direction.

[0013] In one embodiment, an air blowing mechanism is connected to the input terminal, and the air blowing mechanism is positioned above the input terminal and below the output terminal.

[0014] In one embodiment, the blowing mechanism is an ion bar that can blow out ion wind.

[0015] In one embodiment, the first conveying mechanism and / or the second conveying mechanism includes a conveyor belt for carrying and conveying the product, the conveyor belt having a plurality of vacuum adsorption holes for drawing in airflow so that the product can be vacuum adsorbed onto the conveyor belt.

[0016] In one embodiment, the cutting mechanism further includes a first linear module and a second linear module. The first linear module is disposed on the frame, the second linear module is movably disposed on the first linear module, and the cutter is movably disposed on the second linear module. The second linear module and the cutter can move together relative to the first linear module along a cutting direction perpendicular to the conveying direction and the vertical direction, and the cutter can move relative to the second linear module along the vertical direction.

[0017] In one embodiment, the cutting and conveying device further includes a plurality of robotic arms for gripping the product, the plurality of robotic arms being arranged next to the second conveying mechanism and spaced apart sequentially along the conveying direction.

[0018] The aforementioned cutting and conveying equipment, by arranging a first conveying mechanism and a second conveying mechanism adjacent to each other along a conveying direction, with the first conveying mechanism passing through the cutting mechanism and the second conveying mechanism conveying products at a speed greater than that of the first conveying mechanism, allows the product to be cut by the cutting mechanism during its conveying process on the first conveying mechanism. When the product is first conveyed to the second conveying mechanism, the product being conveyed earlier can be conveyed at a faster speed, while the product being conveyed later is still being conveyed at a slower speed by the first conveying mechanism. This allows the product being conveyed earlier and the product being conveyed later to quickly separate without the need for other mechanisms, facilitating the robotic arm's gripping of the cut product in subsequent processes. This avoids damage to the product during gripping and prevents interference between adjacent robotic arms when gripping products. Attached Figure Description

[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0026] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0031] This application provides a cutting and conveying device for cutting large glass panels into multiple small glass pieces, and also for conveying the glass panels and the cut glass pieces to subsequent processes.

[0032] The structure of the cutting and conveying equipment in this application will be described below, taking the glass panel used for the screen of 3C electronic products as an example.

[0033] It is understood that, in other embodiments, the cutting and conveying equipment of this application is not limited to cutting and conveying only glass panels, but can also cut and convey any product, and can also increase the distance between any two adjacent products after cutting online, which is not limited here.

[0034] See Figure 1 , Figure 1 A schematic diagram of a cutting and conveying device 10 according to an embodiment of this application is shown. The cutting and conveying device 10 according to an embodiment of this application includes a cutting mechanism 100 and a conveying mechanism 200. The conveying mechanism 200 passes through the cutting mechanism 100, and a robot arm is disposed adjacent to the conveying mechanism 200. The conveying mechanism 200 is used to convey products 40 (e.g., glass panels) along a conveying direction (X direction shown in the figure); the cutting mechanism 100 is used to cut large pieces of products 40 into smaller pieces of products 40 arranged sequentially when they are conveyed by the conveying mechanism 200; the robot arm is used to grab the smaller pieces of products 40 when they are conveyed by the conveying mechanism 200, so as to transfer the products 40 to the next process.

[0035] Specifically, the cutting mechanism 100 includes a frame 110 and a cutter (not shown) movably mounted on the frame 110. A conveying mechanism 200 passes through the frame 110, and the cutter is movable relative to the frame 110 to cut large pieces of product 40. More specifically, the cutter is movably connected to the frame 110 via a transmission assembly 120. In one embodiment, the transmission assembly 120 is a two-axis module, including a first linear module 121 and a second linear module 122. The first linear module 121 is mounted on the frame 110, and the second linear module 122 is movably mounted on the first linear module 121. The cutter is movably mounted on the second linear module 122. During movement, the cutter can move relative to the second linear module 122 in the vertical direction (Z direction shown in the figure) to descend and contact the product 40; the second linear module 122 and the cutter can move together in a cutting direction perpendicular to the conveying direction and the vertical direction (Y direction shown in the figure), so that the cutter can cut a large piece of product 40 along the cutting direction. Of course, the cutter is not limited to being connected to the frame 110 via the transmission assembly 120; for example, the cutter can also be connected to a robotic arm, which is not limited here.

[0036] In order to improve production efficiency and enable the product 40 to maintain a high turnover rate during conveying, in a preferred embodiment, there are multiple robotic arms, which are arranged sequentially and at intervals along the conveying direction, so that multiple pieces of the cut product 40 can be grasped by multiple robotic arms at the same time.

[0037] However, as described in the background section, the small gap between adjacent product pieces 40 after cutting makes it difficult for robotic arms to grasp the cut product 40, which is being transported at high speed on the conveyor line, in subsequent processes. This can easily damage adjacent product pieces 40 after cutting. Furthermore, the small gap between adjacent product pieces 40 can also cause interference between adjacent robotic arms when grasping product 40.

[0038] Therefore, in order to solve the above problems, the applicant has improved the above embodiments. Figure 2 and Figure 3 An improved embodiment of the cutting conveying mechanism 200 is shown. In the improved embodiment, the conveying mechanism 200 is divided into a first conveying mechanism 210 and a second conveying mechanism 220 arranged adjacent to each other along the conveying direction. The first conveying mechanism 210 passes through the frame 110 of the cutting mechanism 100 and is used to convey the product 40 at a first conveying speed V1. When the large product 40 is conveyed on the first conveying mechanism 210, it can be cut into small pieces by the cutting mechanism 100. The second conveying mechanism 220 is used to convey the small pieces of product 40 obtained after cutting at a second conveying speed V2, which is greater than the first conveying speed V1.

[0039] Thus, there is a speed difference ΔV between the second conveying mechanism 220 and the first conveying mechanism 210 when conveying product 40. This speed difference is ΔV = V2 - V1. It is easy to understand that when product 40 is cut by the cutting mechanism 100 during the conveying process of the first conveying mechanism 210, the product 40 that is conveyed first among two adjacent products 40 (i.e., the product 40 on the right in the figure) can be conveyed by the second conveying mechanism 220 at a faster conveying speed the moment it is first conveyed to the second conveying mechanism 220, while the product 40 that is conveyed later... (That is, the product 40 on the left of the two adjacent products 40 in the figure) is still being conveyed by the first conveying mechanism 210 at a slower speed, so that the product 40 being conveyed in front can move forward quickly without the need for other mechanisms. Therefore, it can be ensured that the product 40 being conveyed in front and the product 40 being conveyed behind can quickly create a distance, so that the robot can easily grasp the cut product 40 in the subsequent process. This can avoid the robot from damaging the product 40 when grasping it, and also avoid the adjacent robot from interfering with each other when grasping the product 40.

[0040] Optionally, the speed difference ΔV between the second conveying speed V2 and the first conveying speed V1 is ≤250mm, which ensures that after the distance between two adjacent products 40 is increased, the spacing between the two products 40 is neither too large nor too small, thus ensuring a suitable spacing.

[0041] In some embodiments, the first conveying speed V1 may be less than or equal to 250 mm / s, and the second conveying speed V2 may be less than or equal to 500 mm / s. The specific speed is not limited, as long as the speed difference ΔV is less than or equal to 250 mm / s. For example, in one embodiment, the first conveying speed V1 is 250 mm / s, and the second conveying speed V2 is 500 mm / s.

[0042] It is worth noting that in some cases, when product 40 is a glass panel, the material of the glass panel can be soft glass. In this case, after the glass panel is cut, the two adjacent glass pieces may still stick together. Even if the conveying speed of the second conveying mechanism 220 is higher than that of the first conveying mechanism 210, the product 40 transported later may still be carried into the second conveying mechanism 220 by the product 40 transported earlier, causing the two adjacent product pieces 40 to not be completely separated.

[0043] To resolve this issue, see [link / reference] Figure 2 and Figure 3Based on the above embodiment, the height of the first conveying mechanism 210 is higher than that of the second conveying mechanism 220, so that there is a height difference ΔH between the first conveying mechanism 210 and the second conveying mechanism 220. By creating a height difference between the first conveying mechanism 210 and the second conveying mechanism 220, when one of the two adjacent product pieces 40 is completely or mostly detached from the first conveying mechanism 210, it will fall onto the second conveying mechanism 220. Since the conveying speed of the second conveying mechanism 220 is higher than that of the first conveying mechanism 210, the distance between the two adjacent product pieces 40 after cutting can be quickly increased, thereby ensuring that the two adjacent product pieces 40 are separated quickly and avoiding the phenomenon that the two adjacent product pieces 40 are still unable to be completely separated due to some adhesion after cutting.

[0044] Optionally, the height difference ΔH between the first conveying mechanism 210 and the second conveying mechanism 220 is ≤150mm. This ensures that the product 40 does not fall too high, thus preventing the product 40 from being damaged and ensuring that there is a time difference between the two products 40 falling onto the second conveying mechanism 220, thereby ensuring the spacing between the two products 40.

[0045] In one embodiment, the first conveying mechanism 210 is set at a height of 1050mm and the second conveying mechanism 220 is set at a height of 900mm. Of course, the heights of the first conveying mechanism 210 and the second conveying mechanism 220 can be arbitrary and are not limited here.

[0046] Preferably, the distance between the first conveying mechanism 210 and the second conveying mechanism 220 is set to be sufficiently close, i.e., as... Figure 4 As shown, the first conveying mechanism 210 has an output end 211 near the second conveying mechanism 220, and the second conveying mechanism 220 has an input end 221 near the first conveying mechanism 210. The output end 211 and the input end 221 are arranged adjacent to each other in the conveying direction, and the output end 211 is located above the input end 221 in the vertical direction. In this way, after the product 40 falls from the first conveying mechanism 210, it can fall entirely onto the second conveying mechanism 220. This avoids the situation where only a small portion of the product 40 falls onto the second conveying mechanism 220 at the moment of falling due to the large distance between the first conveying mechanism 210 and the second conveying mechanism 220 in the conveying direction. This also prevents the product 40 from falling to the ground from the second conveying mechanism 220 due to imbalance.

[0047] Furthermore, based on one of the above embodiments, combined with Figure 2 and Figure 4As shown, an air blowing mechanism 300 is connected to the input end 221 of the second conveying mechanism 220. The air blowing mechanism 300 is positioned above the input end 221 and below the output end 211 of the first conveying mechanism 210. Figure 2 and Figure 4 As shown, when product 40 is conveyed to the output end 211 of the first conveying mechanism 210, product 40 will be exposed at the output end 211 of the first conveying mechanism 210. The part of product 40 exposed at the output end 211 of the first conveying mechanism 210 will be suspended and located above the input end 221 of the second conveying mechanism 220. By setting an air blowing mechanism 300, the air blowing mechanism 300 can blow air on the suspended part of product 40, which can slow down the falling speed of product 40 to the second conveying mechanism 220. Especially when product 40 is soft glass, the suspended part of product 40 can float under the action of airflow, thus preventing product 40 from falling rapidly onto the second conveying mechanism 220, thereby also preventing product 40 from being damaged due to rapid falling.

[0048] Furthermore, the blowing mechanism 300 is an ion bar that can blow out ion wind. By blowing out ion wind, it can not only slow down the product 40 falling to the second conveying mechanism 220 as mentioned above, but also eliminate static electricity on the product 40. This can prevent static electricity on the product 40 from attracting dust to the surface of the product 40, and thus prevent static electricity from affecting the results of subsequent defect detection of the product 40.

[0049] Regarding the structure of the first conveying mechanism 210 and the second conveying mechanism 220, as follows: Figure 2 As shown, the first conveying mechanism 210 and the second conveying mechanism 220 include conveyor belts 222, which are used to convey the product 40. In the embodiment shown in the figure, the first conveying mechanism 210 and the second conveying mechanism 220 each include multiple conveyor belts 222, which are arranged sequentially along the cutting direction. Of course, it can also be a single conveyor belt 222 with a relatively wide dimension along the cutting direction.

[0050] It is understood that the first conveying mechanism 210 and the second conveying mechanism 220 are not limited to the conveying method of the conveyor belt 222, but can also be a structure in which multiple conveying rollers are arranged in sequence for conveying, and there is no limitation on this.

[0051] In addition, when product 40 is conveyed on conveyor belt 222, in order to prevent product 40 from slipping relative to conveyor belt 222, multiple vacuum adsorption holes (not shown in the figure) are opened on conveyor belt 222. The vacuum adsorption holes are connected to a vacuum pump. By using the vacuum pump to draw a vacuum, the vacuum adsorption holes can draw in airflow, so that product 40 can be vacuum adsorbed on conveyor belt 222 and in close contact with conveyor belt 222, avoiding product 40 slipping on conveyor belt 222 and causing wear of product 40.

[0052] Therefore, the cutting and conveying equipment 10 provided in this application divides the conveying mechanism 200 into a first conveying mechanism 210 and a second conveying mechanism 220. The first conveying mechanism 210 and the second conveying mechanism 220 have a speed difference, and the first conveying mechanism 210 and the second conveying mechanism 220 have a height difference. This enables the rapid separation of two adjacent pieces of product 40 after cutting, which facilitates the gripping of the robot arm and avoids damage to the product 40 when the robot arm grips the product 40. This effectively improves the yield rate and production efficiency of the product 40.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
