[0034] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0035] This embodiment provides a material conveying device for moving and simultaneously rotating a carrier 500 for carrying materials. The materials include, but are not limited to, products to be processed 600. For example, the materials can also be finished products or other objects or materials that need to be conveyed. It should also be noted that, in the accompanying drawings, the material conveying device is mounted on a base plate 700. However, in practical applications, the various parts of the material conveying device are not limited to being mounted on the same plate, but may also be mounted on a workbench or different mounting carriers. For example, one part may be mounted on a workbench, while another part may be mounted on the ground or a wall. That is, the base plate 700 in the accompanying drawings is merely an illustration of the mounting carrier for the material conveying device, and not a limitation thereof.

[0036] The material conveying device provided in this embodiment is described in detail below.

[0037] like Figures 1 to 6 As shown, the material conveying device provided in this embodiment includes a moving component, a rotating component, and a connecting rod 400. The moving component includes a driving member 100 for driving the carrier 500 to reciprocate within a plane between its initial position and a target position. The rotating component includes a fixed end component 200, a follower end component 300, and a connecting rod 400. The fixed end component 200 includes a first base 210 and a first mounting base 220. The first mounting base 220 is rotatably mounted on the first base 210 about a first axis perpendicular to the first axis. The aforementioned plane; the follower end assembly 300 includes a second base 310 and a second mounting base 320. The second base 310 is fixedly connected to the output part 120 of the moving assembly. The second mounting base 320 is rotatably disposed on the second base 310 about a second axis perpendicular to the aforementioned plane, and the second mounting base 320 can be fixedly connected to the carrier 500. The connecting rod 400 is disposed parallel to the aforementioned plane. One end of the connecting rod 400 is movably disposed on the first mounting base 220 along its axial direction, and the other end is fixedly connected to the second mounting base 320.

[0038] Of course, in other embodiments of the present application, the connection manner of the connecting rod 400 and the first mounting seat 220 and the second mounting seat 320 is not limited to the above form, for example: the connecting rod 400 can also be movably arranged in the axial direction at one end of the second mounting seat 320, and the other end is fixedly connected with the first mounting seat 220; or, the two ends of the connecting rod 400 are movably arranged in the axial direction of the first mounting seat 220 and the second mounting seat 320, respectively. That is, as long as the connecting rod 400 is movable in the axial direction, that is, it can be telescopic in the axial direction to adapt to the changing distance between the first mounting seat 220 and the second mounting seat 320, the specific connection manner of the two ends of the connecting rod 400 and the first mounting seat 220 and the second mounting seat 320 can not be limited.

[0039] The material conveying device provided by the embodiment can make the at least one end of the connecting rod 400 relatively move in the axial direction of the mounting seat connected with the end to adapt to the changing distance between the fixed end assembly 200 and the follow-up end assembly 300 connected with the output part 120 of the driving part 100, and make the second mounting seat 320 in the follow-up end assembly 300 relatively rotate about the second axis under the limiting action and rotate from the initial angle to another angle. By changing the distance between the translational trajectory of the fixed end assembly 200 and the carrier 500, the carrier 500 can be rotated to the target angle when being translated to the target position.

[0040] That is, the material conveying device provided by the embodiment can make the carrier 500 for carrying materials automatically rotate to the target angle in the process of being translated by the rotating assembly, which not only can replace manual operation and reduce the dependence on manual operation, thereby reducing the labor cost, but also does not need to set a rotating driving part, so the device and energy cost are low. The carrier 500 and the materials thereon are rotated while moving, that is, the two-dimensional actions of translation and rotation are combined and performed synchronously, which can greatly improve the conveying efficiency, thereby improving the production efficiency and reducing the cost per product.

[0041] In addition, in the process of conveying the carrier 500 and the materials thereon by using the material conveying device provided by the embodiment, human intervention is less, and there is no rotating power source, so the safety risk in the production process is low and the safety is high. In addition, using the rotating assembly to replace the rotating power source such as a rotating cylinder or a rotating motor can effectively save space in the height direction, so that the whole device is convenient for matching operation with other automatic devices, and there is no problem of insufficient rotating torque and inertia.

[0042] Further, using the material conveying device provided by the embodiment, only the carrier 500 needs to be replaced to meet the conveying requirements of different products, which has good compatibility and strong applicability and is conducive to meeting the individualization and diversification requirements of consumers on 3C products.

[0043] It should be further noted that, as shown in Figure 1 and Figure 2 , changing the distance between the translation trajectory of the fixed end assembly 200 and the carrier 500 can adjust the angular rotation range of the carrier 500. In addition, when the distance between the fixed end assembly 200 and the translation trajectory of the carrier 500 is unchanged, the translation stroke of the carrier 500 corresponds to its angular rotation range. The longer the translation stroke of the carrier 500, the larger its angular rotation range. The shorter the translation stroke of the carrier 500, the smaller its angular rotation range. That is, the angular rotation range of the carrier 500 can also be controlled by controlling the translation distance of the carrier 500. Preferably, in the embodiment, the stroke end of the carrier 500 is its target position, and when the carrier 500 translates to its target position, its rotation angle reaches the target angle of 90°. In theory, the angular rotation range of the carrier 500 and the material provided by the material conveying device is greater than 0° and less than 180°. Therefore, as long as the target angle is within this range, the embodiment can be implemented.

[0044] As shown in Figure 3 and Figure 5 , in the embodiment, the first mounting seat 220 is provided with a plug-in hole 223, one end of the connecting rod 400 is inserted into the plug-in hole 223 and can slide along the axial direction of the plug-in hole 223, and the other end of the connecting rod 400 is fixedly connected with the second mounting seat 320. In this way, when the driving part 100 drives the follower end assembly 300, the carrier 500 and the material thereon to translate, the end of the connecting rod 400 connected with the second mounting seat 320 moves and makes the second mounting seat 320 rotate around the second axis, while the end of the connecting rod 400 connected with the first mounting seat 220 extends and retracts in the plug-in hole 223, thereby driving the first mounting seat 220 to rotate around the first axis.

[0045] Specifically, as shown in Figure 5 , in the embodiment, a linear bearing 240 is arranged in the plug-in hole 223, and the connecting rod 400 is slidably inserted into the center hole of the linear bearing 240. Further, the linear bearing 240 can have two, and the type can be a lengthened type to better slide with the connecting rod 400. By arranging the linear bearing 240 in the plug-in hole 223, the frictional resistance when the connecting rod 400 slides and extends can be reduced, so that the extension and retraction can be smoother, and the wear of the connecting rod 400 can be reduced.

[0046] Of course, the connection mode of the connecting rod 400 and the first mounting seat 220 is not limited to the form of hole-shaft cooperation, for example, the two can also be connected through guide rail sliding, specifically, the first mounting seat 220 is provided with a first guide rail, and the connecting rod 400 is provided with a second guide rail along the axial direction, and the first guide rail and the second guide rail are slidingly connected. That is, as long as the connecting rod 400 can move relative to the first mounting seat 220 along the axial direction, the specific connection mode between the connecting rod 400 and the first mounting seat 220 can not be limited in the application.

[0047] As shown in Figure 3 and Figure 5 , in the embodiment, the top surface of the second mounting seat 320 is used for fixed connection with the bottom surface of the carrier 500, and the connecting rod 400 is lower than the top surface of the second mounting seat 320. In this way, the connecting rod 400 is located below the carrier 500, and does not interfere with the carrier 500, the materials on the carrier 500, and the process operation above the carrier 500, which is safe and saves space.

[0048] As shown in Figure 5 , in the embodiment, the first base 210 includes a first rotating shaft 211, and an axis of the first rotating shaft 211 forms a first axis; the first mounting seat 220 is provided with a first hole, and the first rotating shaft 211 is inserted into the first hole and can rotate relative to the first hole. Of course, in other embodiments of the application, the first mounting seat 220 can also include the first rotating shaft 211, and the first base 210 is provided with the first hole, which can also achieve the rotation of the first mounting seat 220 relative to the first base 210.

[0049] More specifically, the first hole and the first rotating shaft 211 are connected through a first rotating bearing 230, an inner ring of the first rotating bearing 230 is fixedly sleeved on the outside of the first rotating shaft 211, and an outer ring of the first rotating bearing 230 is fixedly arranged in the first hole. Through the first rotating bearing 230, the frictional resistance between the first mounting seat 220 and the first rotating shaft 211 can be effectively reduced, so that the rotation of the first mounting seat 220 is more flexible.

[0050] In the embodiment, the first mounting seat 220 includes a first connecting flange 221, and a central hole of the first connecting flange 221 forms the first hole, that is, the first rotating shaft 211 is connected with the first connecting flange 221 through the first rotating bearing 230.

[0051] In the embodiment, the first mounting seat 220 further includes a mounting block 222, the mounting block 222 is fixedly connected with the first connecting flange 221, and a plug-in hole 223 is arranged in the mounting block 222.

[0052] In the embodiment, as shown in Figure 5As shown, the first mounting base 220 also includes a mounting plate 224. The bottom surface of the mounting plate 224 is fixedly connected to the first connecting flange 221, and the top surface is fixedly connected to the mounting block 222, serving as a carrier for connecting the first connecting flange 221 and the mounting block 222 or both.

[0053] Continue as Figure 5 As shown, in this embodiment, the second base 310 includes a second rotating shaft 311, the axis of which forms a second axis; the second mounting base 320 is provided with a second hole, and the second rotating shaft 311 is inserted into the second hole and can rotate relative to it. Of course, in other embodiments of this application, the second mounting base 320 may also include a second rotating shaft 311, while the second base 310 is provided with a second hole, which also enables the second mounting base 320 to rotate relative to the second base 310.

[0054] More specifically, the second hole and the second rotating shaft 311 are connected by a second rotating bearing 330. The inner ring of the second rotating bearing 330 is fixedly sleeved on the outside of the second rotating shaft 311, and the outer ring of the second rotating bearing 330 is fixedly installed inside the second hole. This connection via the second rotating bearing 330 effectively reduces the frictional resistance between the second mounting base 320 and the second rotating shaft 311, thereby allowing for more flexible rotation of the second mounting base 320 and the carrier 500 on it.

[0055] In this embodiment, the second mounting base 320 includes a second connecting flange 321, and the center hole of the second connecting flange 321 forms a second hole, that is, the second rotating shaft 311 and the second connecting flange 321 are connected by a second rotating bearing 330.

[0056] In this embodiment, as Figure 6 As shown, the second mounting base 320 also includes a clamping block 322. The clamping block 322 has a through hole, and along the circumference of the through hole, the clamping block 322 has a first end 323 and a second end 324. There is a gap between the first end 323 and the second end 324, allowing the first end 323 and the second end 324 to move closer to each other and further away. The clamping block 322 is fixedly connected to the second connecting flange 321, and the first end 323 and the second end 324 clamp the end of the connecting rod 400 in the through hole. Specifically, after the end of the connecting rod 400 is inserted into the through hole of the clamping block 322, the first end 323 and the second end 324 can be connected and brought closer together by fasteners such as bolts, thereby clamping the end of the connecting rod 400 in the through hole.

[0057] In this embodiment, as Figure 5 and Figure 6As shown, the second base 310 further comprises a connecting plate 312, the second rotating shaft 311 is arranged on the top surface of the connecting plate 312, and the bottom surface of the connecting plate 312 is fixedly connected with the output portion 120 of the moving assembly. Of course, in other embodiments of the present application, the second rotating shaft 311 can also be directly connected with the output portion 120 of the moving assembly.

[0058] In the embodiment, the driving member 100 is a linear driving member, more specifically, a cylinder, further specifically, a rodless cylinder, the fixed portion 110 of which is fixedly installed on the base plate 700, and the output portion 120 of which drives the follower end assembly 300 and the carrier 500 to move. However, in other embodiments of the present application, the driving member 100 is not limited to a cylinder, but can also be a hydraulic cylinder or a linear motor, etc. Moreover, in other embodiments of the present application, the moving assembly can further comprise a transmission assembly, such as a chain transmission assembly, a gear and rack transmission assembly or a belt transmission assembly, etc., the driving member 100 is connected with the transmission assembly, and the transmission assembly can drive the carrier 500 to reciprocate between the initial position and the target position.
