[0044] See below Figure 1 and Figure 2 The utility model provides a conveying device for conveying materials, which specifically includes:

[0045] Annular inner guide rail 10;

[0046] An annular outer guide rail 20, wherein the annular outer guide rail 20 is disposed around the outer side of the annular inner guide rail 10;

[0047] At least two guide rail slides 30, wherein at least one of the guide rail slides 30 is slidably disposed on the annular inner guide rail 10, and at least another of the guide rail slides 30 is slidably disposed on the annular outer guide rail 20;

[0048] A loading plate 40, two ends of which are respectively disposed on at least two of the guide rail slides 30;

[0049] The driving mechanism 50 is drivingly connected to the guide rail slide 30 and is used to drive the two ends of the loading plate 40 to move along the annular inner guide rail 10 and the annular outer guide rail 20 respectively.

[0050] In this embodiment, guide rail slides 30 are respectively arranged on the inner annular guide rail 10 and the outer annular guide rail 20, and the two ends of the loading plate 40 are respectively fixedly connected to the guide rail slides 30, and a driving mechanism 50 is arranged to drive and connect the guide rail slides 30, thereby driving the guide rail slides 30 through the driving mechanism 50, so that the loading plate 40 moves along the inner annular guide rail 10 and the outer annular guide rail 20. In this embodiment, the stable transportation of materials is achieved by adopting an annular guide rail transportation method. The annular guide rail occupies a small area, a large number of workstations can be arranged, and the structure is more compact. Different automation mechanisms can be used to achieve automatic assembly of materials, thereby reducing the material transportation cost and improving the transportation efficiency. At the same time, double annular guide rails are used to support the materials, so that the guide rails are evenly stressed so that the materials can be transported smoothly, and at the same time, excessive shaking of each component during the movement is avoided to affect the automatic assembly of other workstations. In addition, the double annular guide rails have a strong carrying capacity and can transport heavier materials.

[0051] The conveying device provided in this embodiment can be applied to a variety of material conveying scenarios. For example, in the production of electric oil-filled radiator heaters, due to the heavy weight and large volume of the oil-filled radiator body, certain requirements are placed on the carrying capacity and floor space of the conveying device. This embodiment adopts a double annular guide rail design, which can not only improve the carrying capacity of the conveying device, but also save the floor space of the line layout, thereby reducing transportation costs and improving transportation efficiency. In specific application scenarios, the inner annular guide rail 10 and the outer annular guide rail 20 can adopt heavy-duty guide rails, and an aluminum profile base is provided to support the inner annular guide rail 10 and the outer annular guide rail 20, so that the conveying device can carry materials of greater weight, thereby further improving the transportation capacity of the conveying device.

[0052] Combination Figure 2 and Figure 3 As shown, in one embodiment, the guide rail slide 30 includes a base 31, a guide rail pulley 32 and a bearing 33, the guide rail pulley 32 can be horizontally rotatably arranged below the base 31, the bearing 33 can be horizontally rotatably arranged above the base 31, and the loading plate 40 is arranged above the bearing 33;

[0053] The guide rail pulley 32 of at least one of the guide rail slides 30 is slidably disposed on the annular inner guide rail 10 , and the guide rail pulley 32 of at least another of the guide rail slides 30 is slidably disposed on the annular outer guide rail 20 .

[0054] In this embodiment, a guide rail pulley 32 is disposed below the base 31 , so that the guide rail slide seat 30 is slidably disposed on the annular inner guide rail 10 or the annular outer guide rail 20 .

[0055] Combination Figure 4 and Figure 5 As shown, specifically, at least two guide rail pulleys 32 are arranged at intervals below each base 31, and sliding grooves are arranged in the middle of the two guide rail pulleys 32 in the circumferential direction. Slide bars are protruding on both sides of the annular guide rail (annular inner guide rail 10 and / or annular outer guide rail 20), and the annular guide rail is sandwiched between the two guide rail pulleys 32, so that the slide bars on both sides of the annular guide rail are embedded in the sliding grooves, so that the two guide rail pulleys 32 can slide along the annular guide rail. This sliding mode can make the entire guide rail slide seat 30 have not only linear sliding ability but also arc sliding ability, that is, it can slide along the annular guide rail.

[0056] In a specific embodiment, four guide rail pulleys 32 are arranged below each base 31. The four guide rail pulleys 32 are arranged in an array to form a structure of two rows and two columns, thereby forming two groups of guide rail pulleys 32, each group including two guide rail pulleys 32, and the annular guide rail is sandwiched between the two groups of guide rail pulleys 32, thereby improving the stability of movement. More specifically, the guide rail slide 30 on the annular inner guide rail 10 and the annular outer guide rail 20 can adopt the above structure.

[0057] By horizontally rotating the bearing 33 above the base 31, the bearing 33 is used to support the loading plate 40, and the rotation of the bearing 33 increases the freedom of the guide rail slide 30 in the horizontal direction. In a specific application scenario, the bearing 33 can be a cross roller bearing. When the guide rail slide 30 moves to the turning point of the annular inner guide rail 10 or the annular outer guide rail 20, the cross roller bearing can increase the freedom of the guide rail slide 30 by self-rotation, so that the guide rail slide 30 passes the turning point smoothly. In addition, the loading plate 40 and the bearing 33 in this embodiment can be fixed by hexagon socket screws and a connecting plate. Specifically, a bakelite connecting plate for supporting materials and a steel plate connecting plate connected to the bottom of the bakelite connecting plate are provided at the bottom of the loading plate 40, and a bearing connecting plate is provided above the bearing 33, and the fixed connection between the bearing 33 and the bearing connecting plate, the fixed connection between the bearing connecting plate and the steel plate connecting plate, and the fixed connection between the steel plate connecting plate and the bakelite connecting plate are realized in turn by hexagon socket screws.

[0058] In one embodiment, the driving mechanism 50 is drivingly connected to at least one of the guide rail slides 30, and at least another guide rail slide 30 also includes a linear guide rail 34 horizontally arranged above the base 31 and a guide rail slider 35 slidably arranged on the linear guide rail 34, and the bearing 33 can be horizontally rotatably arranged above the guide rail slider 35, and the linear guide rail 34 is perpendicular to the annular outer guide rail 20 or the annular inner guide rail 10.

[0059] In the present embodiment, at least two guide rail slides 30 are provided, wherein at least one guide rail slide 30 is connected to the driving mechanism 50, thereby driving the loading plate 40 to move along the annular inner guide rail 10 and the annular outer guide rail 20 through the driving mechanism 50, and when moving to the turning point of the annular outer guide rail 20 and / or the annular inner guide rail 10, the other guide rail slide 30 can achieve a certain degree of movement in the horizontal direction through the linear guide rail 34 and the guide rail slider 35. Specifically, the guide rail slider 35 can slide on the linear guide rail 34 according to the angle requirement of the turning point, thereby driving the guide rail slide 30 and the loading plate 40 to adaptively adjust to adapt to the angle requirement of the turning point, thereby improving the degree of freedom of the loading plate 40 at the turning point, reducing the friction between the annular inner guide rail 10, the annular outer guide rail 20 and the guide rail slide 30, thereby avoiding the problem of unstable transportation or jamming at the turning point. Specifically, when the loading plate 40 moves to a turning point, the speeds of the inner and outer sides are different, and the speed of the inner side is slower than that of the outer side, which may cause the loading plate 40 to become stuck easily. At this time, by providing a linear guide rail 34 and a guide rail slider 35 in the guide rail slide 30 on one side of the loading plate 40, the loading plate 40 can slide back and forth on this side, that is, the loading plate 40 can slide back and forth at the turning point according to the motion trajectory requirements, and combined with the rotation function of the bearing 33, the degree of freedom of the loading plate 40 at the turning point can be improved, so that the loading plate 40 can move smoothly at the turning point.

[0060] In a specific application scenario, a guide rail slide 30 including a linear guide 34 and a guide rail slider 35 may be provided on only one of the guide rails, the annular inner guide rail 10 or the annular outer guide rail 20, but not provided on the other guide rail, so that the degree of freedom required at the turning point in most cases can be met. For example, in the present embodiment, a guide rail slide 30 including a linear guide 34 and a guide rail slider 35 may be provided on only the annular outer guide rail 20, but not provided on the annular inner guide rail 10, and the guide rail slide 30 including a linear guide 34 and a guide rail slider 35 is connected to the driving mechanism 50 on the annular inner guide rail 10. In some scenarios, the guide rail slide 30 on the annular inner guide rail 10 and the guide rail slide 30 on the annular outer guide rail 20 may also include a linear guide 34 and a guide rail slider 35, so as to further improve the degree of freedom at the turning point.

[0061] Combination Figure 7 and Figure 8 As shown, in one embodiment, the driving mechanism 50 includes a sprocket drive member 51, a sprocket 52 and a chain 53, the chain 53 has the same shape as the annular inner guide rail 10 and / or the annular outer guide rail 20, the sprocket drive member 51 is drivingly connected to the sprocket 52, and the sprocket 52 is connected to the chain 53;

[0062] At least one of the guide rail slides 30 further includes a connecting member 36 disposed on the base 31 , and the connecting member 36 is connected to the chain 53 .

[0063] In this embodiment, the sprocket drive 51 drives the sprocket 52, the sprocket 52 is connected to the chain 53, the chain 53 is connected to the guide rail slide 30 through the connecting member 36 on the base 31, and the chain 53 has the same shape as the annular inner guide rail 10 and / or the annular outer guide rail 20. On this basis, the sprocket drive 51 drives the sprocket 52 to rotate, the sprocket 52 drives the chain 53 to move along the guide rail direction of the annular inner guide rail 10 and / or the annular outer guide rail 20, and then connects to the guide rail slide 30 through the connecting member 36, and drives the loading plate 40 to move on the annular inner guide rail 10 and / or the annular outer guide rail 20, thereby realizing the transmission of materials.

[0064] In specific application scenarios, the sprocket drive 51 can use a servo motor. The servo motor has the advantages of high-precision control, smooth operation, and the ability to complete acceleration, deceleration, and positioning in a short time. The transmission mechanism composed of the servo motor, sprocket 52, and chain 53 has the advantages of strong overload capacity, accurate transmission ratio, and reliable operation. It can achieve precise displacement of materials and can also better control displacement errors, thereby improving the consistency of subsequent automated assembly operations.

[0065] In one embodiment, a plurality of sprockets 52 are provided and are located at arc-shaped corners of the annular inner guide rail 10 and / or the annular outer guide rail 20 .

[0066] In this embodiment, sprockets 52 are provided at multiple arc-shaped corners of the annular inner guide rail 10 and / or the annular outer guide rail 20, so that the tension of the chain 53 is maintained by the sprocket 52, ensuring that the chain 53 can smoothly transition at the arc-shaped corners, and the transmission direction of the chain 53 can be changed, so that the loading plate 40 can move along the transportation direction and convey materials.

[0067] For example, Figure 1 As shown, the annular inner guide rail 10 and the annular outer guide rail 20 both have four arc-shaped bends, and four sprockets 52 are correspondingly arranged, and the four sprockets 52 are respectively located at the four arc-shaped bends on the inner side of the annular inner guide rail 10, and are connected to the chain 53, so that the shape of the entire chain 53 is adapted to the shape of the annular inner guide rail 10 and the annular outer guide rail 20, so that the motion trajectory of the guide slide 30 connected to the chain 53 is the same as the shape of the annular inner guide rail 10 and / or the annular outer guide rail 20; at the same time, the chain 53 can be driven by four sprockets 52 at the same time, thereby improving working reliability and stability.

[0068] In one embodiment, the conveying device further comprises a positioning device 60 disposed on the annular inner guide rail 10 and / or the annular outer guide rail 20;

[0069] At least one of the guide rail slides 30 further includes a positioning member 37 disposed on the base 31 , and the positioning device 60 can be positioned with the positioning member 37 .

[0070] In this embodiment, by providing a positioning device 60 on the guide rail, and providing a positioning member 37 on the base 31 of at least one guide rail slide 30 corresponding to the guide rail, the positioning device 60 and the positioning member 37 are used for positioning, so that the material on the loading plate 40 can be accurately transported to the working position. Specifically, the positioning device 60 can be provided only on the annular inner guide rail 10 or the annular outer guide rail 20, or the positioning device 60 can be provided on both the annular inner guide rail 10 and the annular outer guide rail 20.

[0071] In one embodiment, the positioning device 60 includes a positioning seat 61, a positioning drive member arranged on the positioning seat 61, and a limit block 62 slidable up and down on the positioning seat, the positioning drive member drivingly connects the limit block 62, and a positioning groove 621 for positioning the positioning member 37 is arranged on the top of the limit block 62, and the limit block 62 is used to position with the positioning member 37 after being driven to rise.

[0072] In this embodiment, the positioning device 60 is provided with a positioning drive member and a limit block 62 on the positioning seat 61, and the positioning drive member is used to drive the limit block 62 to slide up and down on the positioning seat, so that after the limit block 62 is driven to rise, it is positioned with the positioning member 37 through the positioning groove 621 set on the top of the limit block 62.

[0073] Specifically, when the guide rail slide 30 drives the loading plate 40 to reach the designated working position (i.e., the position of the positioning device 60) on the annular inner guide rail 10 or the annular outer guide rail 20, the positioning drive member drives the limit block 62 to rise, and makes the positioning groove 621 on the top of the limit block 62 reach a position that can abut against the positioning member 37, so that the guide rail slide 30 and the loading plate 40 are limited by the positioning member 37 to avoid the movement or shaking of the material position during the working process, ensure the safety of the working process, and also facilitate the staff to perform corresponding work on the material. Among them, the shape of the positioning groove 621 is adapted to the shape of the positioning member 37 to improve the positioning stability. For example, the positioning member 37 is a columnar structure that protrudes laterally and is arranged on the side of the base 31, and the positioning groove 621 is a semicircular groove structure with an opening facing upward. In this embodiment, a positioning member 37 and a connecting member 36 can be set on the guide rail slide 30 on the annular inner guide rail 10, and the connecting member 36 and the positioning member 37 are respectively set on the inner side and the outer side of the guide rail slide 30. In order to improve the versatility, the connecting member 36 and the positioning member 37 can be connected to the guide rail slide 30 in a detachable manner. At the same time, a positioning device 60 is set on the annular inner guide rail 10 to cooperate in positioning the guide rail slide 30 thereon, and the guide rail slide 30 on the annular outer guide rail 20 is set as a guide rail slide 30 including a linear guide 34 and a guide slider 35.

[0074] In a specific application scenario, the sprocket drive 51 and the positioning device 60 are controlled by a PLC control signal. The sprocket drive 51 drives the guide rail slide 30 and the loading plate 40 to move to the designated working position according to the PLC control signal and then stops. Then the positioning device 60 drives the limit block 62 to rise according to the PLC control signal using the positioning drive. After completing the corresponding material processing work, the positioning drive drives the limit block 62 to descend to cancel the limit on the guide rail slide 30 and the loading plate 40, and the sprocket drive 51 drives the guide rail slide 30 and the loading plate 40 to move to the next designated working position.

[0075] In one embodiment, the guide rail slides 30 are arranged in groups and there are multiple groups, and the loading plates 40 are correspondingly arranged in multiples, and each loading plate 40 is arranged on each group of the guide rail slides 30, each group of the guide rail slides 30 includes a plurality of inner guide rail slides slidably arranged on the annular inner guide rail 10 and an outer guide rail slide slidably arranged on the annular outer guide rail 20, or, each group includes a plurality of outer guide rail slides slidably arranged on the annular outer guide rail 20 and an inner guide rail slide slidably arranged on the annular inner guide rail 10.

[0076] In this embodiment, a plurality of groups of guide rail slides 30 and corresponding plurality of loading plates 40 are arranged on the guide rails, and each group of guide rail slides 30 may include a plurality of inner guide rail slides and one outer guide rail slide, or, each group of guide rail slides 30 may include a plurality of outer guide rail slides and one inner guide rail slide, wherein the inner guide rail slides are arranged on the annular inner guide rail 10, and the outer guide rail slides are correspondingly arranged on the annular outer guide rail 20.

[0077] In this embodiment, by arranging multiple sets of guide rail slides 30 and corresponding multiple loading plates 40 on the guide rails, the layout of the conveying device can be made more compact, thereby improving the transportation capacity of the conveying device, and more materials can be transported by the conveying device. It can be understood that each set of guide rail slides 30 drives a loading plate 40, and the loading plate 40 transports a portion of material, and multiple sets of guide rail slides 30 and multiple loading plates 40 can simultaneously transport more materials on the guide rails.

[0078] In addition, in this embodiment, a plurality of guide rail slides are arranged on one of the guide rails, and only one guide rail slide is arranged on the other guide rail, so that the stability of material transportation can be improved through the cooperation between the guide rail slides. Figure 2 As shown, two inner guide rail slides can be set on the annular inner guide rail 10, and an outer guide rail slide can be set on the annular outer guide rail 20. On this basis, one end of the loading plate 40 is connected to the outer guide rail slide, and the other end is connected to the two inner guide rail slides. In this way, a triangular layout can be formed between an outer guide rail slide and two inner guide rail slides to support the loading plate 40, so that the stability of the loading plate 40 during movement is ensured by using the triangular structure, so that it will not tilt or shake. Further, no linear guide rail 34 and guide rail slider 35 are set on the two inner guide rail slides, and only a connecting member 36 and a positioning member 37 need to be set on both sides of one of the inner guide rail slides. At this time, a linear guide rail 34 and a guide rail slider 35 can be set in the outer guide rail slide. In this way, the degree of freedom of the loading plate 40 at the turning point can be improved while ensuring the stable movement of the loading plate 40.

[0079] Of course, in other scenarios, multiple outer guide rail slides can be slidably arranged on the annular outer guide rail 20, and an inner guide rail slide can be arranged on the annular inner guide rail 10, and a linear guide rail 34 and a guide slider 35 can be arranged in the inner guide rail slide. In addition, it should be noted that when multiple guide rail slides are arranged on a guide rail, the multiple guide rail slides are independently arranged side by side and are fixed by connecting the loading plate 40. At the same time, only one of the guide rail slides needs to be connected to the chain 53.

[0080] In one embodiment, a baffle 41 for limiting the position of the material is disposed upwardly on the loading plate 40 , and the baffle 41 encloses and forms a receiving cavity for loading the material. At least one through hole 42 is opened on the loading plate 40 .

[0081] In this embodiment, if Figure 1 and Figure 7 As shown, the loading plate 40 is provided with a baffle 41 upwardly for limiting the position of the material, and the baffle 41 encloses a receiving cavity for loading the material. When the material is placed in the receiving cavity and conveyed, the receiving cavity enclosed by the baffle 41 may not be a completely closed receiving cavity. For example, only L-shaped baffles 41 are provided at the four corners of the loading plate 40. It is only necessary to ensure that the material does not fall out of the loading plate 40 under the action of the baffle 41, thereby ensuring the safety of the conveying process. At the same time, at least one through hole 42 is provided on the loading plate 40. The through hole 42 can reduce the weight of the loading plate 40 and reduce the load of the guide rail. In some specific scenarios, for example, when the conveying device is used to convey the radiator body of an electric oil radiator heater, since an oil bag is provided under the radiator body, the through hole 42 can be used to avoid interference with the oil bag and cause wear, thereby ensuring the material safety of the radiator body.

[0082] In one embodiment, the annular inner guide rail 10 and the annular outer guide rail 20 have the same shape and the same spacing.

[0083] In this embodiment, by setting the annular inner guide rail 10 and the annular outer guide rail 20 to have the same shape and equal spacing at all locations, the stability of the material when being transported on the guide rail can be ensured. It can be understood that the arc-shaped turns of the annular inner guide rail 10 and the annular outer guide rail 20 are concentrically arranged, and the spacing between the arc-shaped turns of the two is also equal to the spacing at other positions, so that it can be ensured that the material moves smoothly when it is transported to the arc-shaped turns without getting stuck. Specifically, the annular inner guide rail 10 and the annular outer guide rail 20 may not be a circular ring, for example, they may be set in the shape of a runway, with four sides being straight guide rails and four corners formed by the four sides being arc-shaped guide rails.
