Description

Technical Field

[0001] This application relates to the technical field of automated feeding equipment, and in particular to a lower cylinder casting insert supply device and die casting system. Background Technology

[0002] Currently, in automobile engines, the lower cylinder block is typically formed using a casting process to ensure structural strength, durability, and vibration resistance. A typical lower cylinder block consists of five inserts, each with slightly different specifications and dimensions. During production, the inserts are transported via a conveyor line to a preheating machine for heating before being embedded into the mold for lower cylinder block casting.

[0003] In related technologies, conveyor lines require production personnel to manually lift and place inserts of different specifications and sizes onto the chain plate positioning pins of the conveyor line according to the specifications of each machine model. This results in high labor intensity. Furthermore, the chain plate positioning pins on the conveyor line are fixedly installed on the positioning plate and are only applicable to inserts of a few specific machine models. When an unsuitable insert type is encountered, the entire positioning plate needs to be disassembled and replaced, which is time-consuming, labor-intensive, and affects the continuity of production. Moreover, since there are many specifications and sizes of inserts, manual placement of inserts is prone to errors in material handling, which can lead to workpiece scrap in subsequent production. Summary of the Invention

[0004] Therefore, it is necessary to provide a lower cylinder casting insert supply device and die casting system to address the problems of high labor intensity for existing technicians and workpiece scrapping caused by incorrect material handling.

[0005] A first aspect of this application provides a lower cylinder block casting insert supply device, comprising:

[0006] Frame;

[0007] An upper conveyor line and a lower conveyor line are arranged side by side at intervals along the height direction on the frame. The upper feed end of the upper conveyor line is aligned with the lower discharge end of the lower conveyor line, and the upper discharge end of the upper conveyor line is aligned with the lower feed end of the lower conveyor line.

[0008] A material handling and feeding mechanism is arranged on one side of the upper discharge end and the lower feed end. The material handling and feeding mechanism includes a robotic arm, a material handling and feeding fixture, and an identifier. The material handling and feeding fixture and the identifier are respectively disposed on the robotic arm.

[0009] A transfer pallet, the transfer pallet being disposed on the frame; and,

[0010] A secondary identification device is installed on the frame and aligned with the transfer tray.

[0011] When the lower cylinder casting insert supply device of this solution is working, multiple material frames containing various types of inserts are transferred to the upper conveyor line through the upper feeding end, and then reach the upper discharge end position under the transmission of the upper conveyor line. At this time, according to the preset production requirements of the current model, under the drive of the robotic arm, the specifications and dimensions of different inserts are accurately identified and positioned with the help of the identifier, so that the pick-and-place fixture can grab and transfer multiple inserts of different specifications and dimensions to the transfer tray in sequence. Then, according to the specified error prevention conditions, the secondary identification device will perform a secondary identification and verification of the specifications, dimensions and arrangement order of all inserts in the transfer tray. When there are no abnormalities, the robotic arm drives the pick-and-place fixture to grab all the inserts in the transfer tray at once and transfer them to the preheater for heating, thereby completing the insert feeding and supply operation. Compared with existing technologies, this solution can automatically complete the insert feeding and supply operation without human intervention. After two identification processes, it can ensure that the insert picking and placing is accurate and reliable, avoid the problem of workpiece scrapping during subsequent production, and greatly improve the overall product quality control level.

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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] See Figures 1 to 5 This application illustrates a lower cylinder block casting insert supply device in one embodiment. It is mainly used to accurately pick up and transfer multiple inserts 300 of different specifications and sizes suitable for the current lower cylinder block manufacturing to the downstream preheater so that the lower cylinder block can be cast.

[0038] For example, the lower cylinder block casting insert supply device includes a frame 10, an upper conveyor line 20, a lower conveyor line 30, a material handling mechanism 40, a transfer pallet, and a secondary identification device 50. The frame 10 is the main supporting structure of the entire lower cylinder block casting insert supply device, used to load and integrate the upper conveyor line 20, the lower conveyor line 30, the material handling mechanism 40, the transfer pallet, and the secondary identification device 50.

[0039] For example, the frame 10 can be a frame structure welded from metal components, which is simple in structure, easy to manufacture and low in cost, with high strength and good durability.

[0040] The upper conveyor line 20 and the lower conveyor line 30 are arranged side by side and spaced apart along the height direction on the frame 10. It can be understood that the upper conveyor line 20 is located above the lower conveyor line 30. For example, the upper conveyor line 20 can be directly above or diagonally above the lower conveyor line 30, depending on the actual needs.

[0041] The upper feed end 21 of the upper conveyor line 20 is aligned with the lower discharge end 32 of the lower conveyor line 30, and the upper discharge end 22 of the upper conveyor line 20 is aligned with the lower feed end 31 of the lower conveyor line 30. That is, the upper feed end 21 is located above the lower discharge end 32, and the upper discharge end 22 is located above the lower feed end 31.

[0042] During operation, the material frame 200 containing various types of inserts 300 is conveyed from the upper feed end 21 to the upper discharge end 22; the empty material frame 200 after the insert 300 is picked up is conveyed from the lower feed end 31 to the lower discharge end 32.

[0043] Furthermore, in one embodiment, the lower cylinder block casting insert supply device further includes a first transfer mechanism 60 and a second transfer mechanism 70. The first transfer mechanism 60 is disposed on one side of the upper feed end 21 and the lower discharge end 32, and the first transfer mechanism 60 is provided with a feed port. The second transfer mechanism 70 is disposed on one side of the upper discharge end 22 and the lower feed end 31.

[0044] Understandably, once the material frame 200 containing the inserts 300 reaches the positions of the upper discharge end 22 and the lower feed end 31, after the material handling mechanism 40 has picked up all the inserts 300 from the material frame 200, the second transfer mechanism 70 can lower the empty material frame 200 from the upper discharge end 22 to the lower feed end 31, thus entering the lower conveyor line 30; the lower conveyor line 30 then transports the empty material frame 200 from the lower feed end 31 to the lower... The discharge end 32 is positioned to reach the feeding port, facilitating the replenishment of new inserts 300 into the empty material frame 200. Then, the second transfer mechanism 70 lifts the material frame 200 filled with inserts 300 from the lower discharge end 32 to the upper feeding end 21, thereby entering the upper conveyor line 20. It can then be conveyed again to the pick-and-place execution mechanism 40 through the upper conveyor line 20, realizing cyclic feeding and cyclic use of the material frame 200, greatly improving feeding efficiency.

[0045] In the above embodiments, both the first transfer mechanism 60 and the second transfer mechanism 70 include a lifting power component and a lifting carrier plate, with the lifting carrier plate connected to the lifting power component. The lifting power component drives the lifting carrier plate to move in the height direction, enabling the lifting carrier plate to drive the material frame 200 to flow between the upper conveyor line 20 and the lower conveyor line 30, allowing the material frame 200 to be recycled, reducing the material unloading process of the material frame 200, and improving the feeding efficiency of the insert 300.

[0046] Please continue reading. Figure 2 and Figure 3 Specifically, the material handling mechanism 40 is arranged on one side of the upper discharge end 22 and the lower feed end 31. The material handling mechanism 40 includes a robotic arm 41, a material handling clamp 42 and an identifier 43, which are respectively mounted on the robotic arm 41. The transfer tray is mounted on the frame 10. The secondary identification device 50 is mounted on the frame 10 and aligned with the transfer tray.

[0047] In summary, implementing the technical solution of this embodiment will have the following beneficial effects: When the lower cylinder casting insert supply device of this solution is working, multiple material frames 200 containing various types of inserts 300 are transferred to the upper conveyor line 20 through the upper feed end 21, and then reach the upper discharge end 22 under the transmission of the upper conveyor line 20. At this time, according to the preset production requirements of the current model, under the drive of the robotic arm 41, the specifications and dimensions of different inserts 300 are accurately identified and positioned with the help of the identifier 43, so that... The pick-and-place fixture 42 can sequentially grab and transfer multiple inserts 300 of different specifications and sizes to a transfer tray. Then, according to specified error-proofing conditions, the secondary identification device 50 will again perform secondary identification and verification of the specifications, dimensions, and arrangement order of all inserts 300 in the transfer tray. When no abnormalities are found, the robotic arm 41 drives the pick-and-place fixture 42 to grab all the inserts 300 in the transfer tray at once and transfer them to the preheater for heating, thus completing the insert 300 feeding operation. Compared with existing technologies, this solution can automatically complete the insert 300 feeding operation without human intervention. Furthermore, the two-stage identification process ensures accurate and reliable insertion and placement of inserts 300, avoiding workpiece scrap during subsequent production and greatly improving the overall product quality control level.

[0048] Alternatively, the recognizer 43 may be one of a visual recognition camera, a visual recognition probe, or the like.

[0049] Please continue reading. Figure 3 and Figure 4 In one embodiment, the upper conveyor line 20 includes an upper support, an upper non-powered conveyor assembly 23, and an upper conveyor plate 24. The upper support is provided with an upper feed end 21 and an upper discharge end 22, and the height of the upper support decreases from the upper feed end 21 to the upper discharge end 22. The upper non-powered conveyor assembly 23 is rotatably mounted on the upper support, and the upper conveyor plate 24 is rotatably mounted on the upper non-powered conveyor assembly 23. The upper conveyor plate 24 is used to load and convey the material frame 200 containing various types of inserts 300.

[0050] The upper support, with its decreasing height design, allows the hopper containing the insert 300, placed on the upper unpowered conveyor assembly 23, to move automatically from the upper feed end 21 to the upper discharge end 22 under its own gravity, thus entering the picking range of the material handling actuator 40. This reduces the use of power equipment and lowers the complexity and cost of the equipment structure. The upper conveyor plate 24 supports the material frame 200 and allows the material frame 200 to move along with the upper conveyor plate 24.

[0051] For example, the upper non-powered conveying component 23 can be a non-powered roller, a non-powered chain plate, or other conveying mechanism, which can be selected according to actual needs.

[0052] In this application, the material frame 200 adopts a frame plate structure with an open top, and the interior is used to place at least one row of inserts 300. The material frame 200 has a simple structure and facilitates the material handling fixture 42 to pick up the inserts 300 from the material frame 200, as well as to replenish the empty material frame 200 with inserts 300.

[0053] It is necessary to note that, considering the variety of sizes of the inserts 300 used in the production of the lower cylinder block (usually no less than 5 types), and in order to improve the feeding capacity, the upper unpowered conveying assembly 23 preferably conveys three rows of material frames 200 simultaneously. The sizes of the inserts 300 in different material frames 200 are generally different, and the sizes of the inserts 300 in the same material frame 200 can be the same or partially different (for example, at least 2 types).

[0054] Furthermore, the lower conveyor line 30 includes a lower support, a lower non-powered conveyor assembly 33, and a lower conveyor plate 34. The lower support is provided with a lower feed end 31 and a lower discharge end 32, and the height of the lower support decreases from the lower feed end 31 to the lower discharge end 32. The lower non-powered conveyor assembly 33 is rotatably mounted on the lower support, and the lower conveyor plate 34 is rotatably mounted on the lower non-powered conveyor assembly 33. The lower conveyor plate 34 is used to load and convey empty material frames 200.

[0055] The structure of the lower conveyor line 30 is basically the same as that of the upper conveyor line 20. Therefore, it can achieve the same technical effect as the upper conveyor line 20, such as automatic conveying of empty material frames 200 under gravity. Therefore, it will not be described in detail here.

[0056] It is necessary to note that, based on any of the above embodiments, the surfaces of the upper conveyor plate 24 and the lower conveyor plate 34 are provided with a plurality of limiting blocks arranged at intervals along the circumferential direction, and the plurality of limiting blocks surround to form a limiting groove.

[0057] Preferably, the limiting block is a magnetic block. The bottom of the material frame 200 is locked into the limiting groove. With the combined constraint of the holding force of the limiting block and the magnetic attraction, the material frame 200 can be placed stably and reliably on the upper conveyor plate 24 and the lower conveyor plate 34, avoiding the problem of the material frame 200 shifting and falling due to inertia or instability of the center of gravity after picking up the material.

[0058] Of course, in other embodiments, positioning pins can be used for positioning, adhesive parts can be used for positioning, etc., to limit the material frame 200. The appropriate method can be selected flexibly according to actual needs.

[0059] In one embodiment, multiple pick-and-place fixtures 42 are provided, arranged side by side. Compared to having only one pick-and-place fixture 42, which requires multiple back-and-forth movements under the drive of the robotic arm 41 to sequentially place multiple inserts 300 of different sizes into the transfer tray, resulting in long travel distances, long time consumption, and reduced material handling efficiency, this solution installs multiple pick-and-place fixtures 42 on the robotic arm 41 simultaneously. Under the condition that the robotic arm 41 only performs small travel distances and small angle deflections, multiple pick-and-place fixtures 42 can pick up multiple required inserts 300 of different sizes in one go, saving the travel distance and time consumption of back-and-forth movements. Moreover, multiple pick-and-place fixtures 42 can also place multiple inserts 300 into the transfer tray at one time, improving work efficiency and avoiding confusion and errors in the order and position of the inserts 300.

[0060] The material handling fixture 42 includes a fixture base, a first fixed block, a second fixed block, a first insert rod, and a second insert rod. The first and second fixed blocks are spaced apart and opposite to each other on the fixture base. The first insert rod is located on the first fixed block, and the second insert rod is located on the second fixed block. The surface of the insert 300 facing the upper opening of the material frame 200 has two insertion holes. During material handling, with the robotic arm 41 and the identifier 43 providing alignment, the first and second insert rods are inserted into their respective insertion holes. The tight fit between the insert rods and the hole walls allows the insert 300 to be picked up and removed from the material frame 200. This material handling method is simple, reliable, and highly feasible.

[0061] In order to be inserted into the socket more accurately and effectively, the ends of the first and second inserts are both tapered, and the tapered surface serves as a guide.

[0062] For inserts 300 of different sizes and specifications, the spacing between the two insertion holes on the insert 300 may vary. Therefore, in another embodiment, the pick-and-place fixture 42 further includes a drive source. The drive source has a first drive arm and a second drive arm, which are positioned opposite each other and capable of telescopic movement. The first drive arm is connected to a first fixed block, and the second drive arm is connected to a second fixed block. By driving the first and second fixed blocks closer together or further apart using the drive source, the distance between the first and second insertion rods can be flexibly adjusted, thereby adapting to insertion holes with different spacings. This allows the pick-and-place fixture 42 to be suitable for picking and placing inserts 300 of various sizes and specifications.

[0063] Furthermore, based on any of the above embodiments, the secondary identification device 50 includes a support frame, a visual recognition camera, and a supplementary light source. The visual recognition camera and the supplementary light source are respectively mounted on the support frame and both face the transfer tray. The support frame is used to assemble and integrate the visual recognition camera and the supplementary light source on the frame 10, and to adjust the distance between the visual recognition camera and the supplementary light source and the transfer tray to ensure the visual recognition effect and the supplementary lighting effect. By capturing images of multiple inserts 300 on the transfer tray, the visual recognition camera can identify the specifications and dimensions of each insert 300, and thus identify and judge the placement order and position of all inserts 300 to verify the correctness of the removed inserts 300, ensuring the safe and normal subsequent casting of the lower cylinder block.

[0064] In addition to the above, this application also provides a die-casting system, which includes a lower cylinder block casting insert supply device as described in any of the above embodiments.

[0065] 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.

[0066] 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.
