[0002] With the continuous advancement of automation technology, automated production methods are gradually replacing traditional manual production methods, and their development direction is increasingly moving towards integration. Currently, small workpieces are commonly loaded using vibrating plates.

Vibrating plates often cannot ensure the consistent orientation of the workpieces, necessitating correction during the loading process.

[0003] In the existing technology, the direction of the workpiece is generally detected by a visual imaging mechanism. Specifically, an industrial camera is used to take an image of the workpiece, and the image result is then sent back to a computer for algorithm calculation to finally determine the direction of the workpiece. However, the use of visual imaging mechanisms is expensive.

[0004] Therefore, the above problems need to be solved urgently. Utility Model Content

[0038] Before any embodiments of the present application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.

[0039] In this application, the terms "comprises," "includes," "has," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0040] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent three situations: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0041] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0042] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. associated with a specific value. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0043] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one assembly, or a combination of multiple parts.

[0044] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.

[0045] See also Figures 1 to 4 This embodiment provides a conveying mechanism capable of identifying and correcting workpieces, which is used to convey and correct the workpiece 300 supplied by the vibration plate 100. The conveying mechanism capable of identifying and correcting workpieces includes a frame 1, a conveying channel 2, a transport component 3 and an identification component 4.

[0046] Specifically, the conveying channel 2 is provided on the frame 1 and is connected to the discharge port 200 of the vibration plate 100. The conveying channel 2 includes a loading station, an identification station, and an output station. It is worth noting that the loading station is the entrance of the conveying channel 2, and the output station is the outlet of the conveying channel 2. The vibration plate 100 can supply the workpiece 300 to the loading station.

[0047] The transport assembly 3 is mounted on the frame 1 and is configured to transport the workpiece 300 between the loading station, the identification station, and the output station, and to place the workpiece 300 on any of the three stations. The identification assembly 4 is mounted on the frame 1 and includes an identification member 41 movably mounted above the identification station. The identification member 41 has a first state in which it is inserted into a corresponding connection hole on the workpiece 300 and a second state in which it abuts against the upper side of the workpiece 300.

[0048] In actual application, the vibrating plate 100 first supplies the workpiece 300 to the loading station, and then the transport component 3 transports the workpiece 300 on the loading station to the identification station. Subsequently, the identification component 41 begins to descend and switches to one of the first state and the second state. It should be noted that the identification component 4 can feedback the identification result based on whether the identification component 41 is inserted into the connecting hole. If the identification component 41 is inserted into the connecting hole, it indicates that the direction of the workpiece 300 is correct. Otherwise, it indicates that the direction of the workpiece 300 is wrong. That is, when the identification component 41 is in the first state, it indicates that the direction of the workpiece 300 is correct. When the identification component 41 is in the second state, it indicates that the direction of the workpiece 300 is wrong.

[0049] It is understood that determining the orientation of the workpiece 300 by determining whether the identification member 41 can be inserted into the corresponding connection hole on the workpiece 300 has a simple structure and low cost. Furthermore, existing visual imaging mechanisms are prone to misjudgments due to electronic failures, which can affect production quality and efficiency. However, the above-mentioned method of determining the orientation of the workpiece 300 based on the mechanical fit between the identification member 41 and the workpiece 300 does not involve electronic components, thus avoiding these problems and helping to ensure production quality and efficiency.

[0050] To improve the efficiency of determining the recognition result, the recognition component 4 also includes a connecting rod 42, a first feedback member 43, a second feedback member 44, and a drive member 45. One end of the connecting rod 42 is hinged to the frame 1, and the recognition member 41 is disposed on the connecting rod 42. The first feedback member 43 is disposed at the other end of the connecting rod 42, and the second feedback member 44 is disposed on the frame 1. When the recognition member 41 is in the first state, the first feedback member 43 and the second feedback member 44 are connected to each other and feedback the recognition result. The drive member 45 is disposed on the frame 1 and is used to drive the connecting rod 42 to rotate.

[0051] It should be noted that the first feedback element 43 and the second feedback element 44 can employ a detection structure based on the principle of electrical circuit detection. Specifically, when the first feedback element 43 and the second feedback element 44 are connected, an identification signal is emitted; otherwise, no identification signal is emitted. The identification signal can be provided by light, sound, or any other form that is convenient for staff to observe, and there are no specific limitations on this. It should also be noted that the drive element 45 can be any linear drive structure known in the art, such as a cylinder or linear module, and this embodiment does not impose any specific requirements or limitations on this.

[0052] Furthermore, to prevent the identification member 41 from crushing the workpiece 300, the identification assembly 4 further includes a stopper 46 disposed on the frame 1. The stopper 46 can abut against the connecting rod 42 to prevent the identification member 41 from excessively pressing down on the workpiece 300. Specifically, the stopper 46 is a bolt threaded onto the frame 1, thereby being able to adjust the height of its contact with the connecting rod 42, providing high adaptability.

[0053] If the depth of the connection hole corresponding to the identification member 41 is shallow, the height of the identification member 41 after being inserted into the connection hole will not change much, that is, the height of the identification member 41 will not change much when it switches from the second state to the first state, which puts forward higher requirements for the coordination of the first feedback member 43 and the second feedback member 44, and increases the cost of use. In order to avoid the above problem, the identification member 41 is located on the side of the connecting rod 42 away from the first feedback member 43. Such a setting can form two force arms of different lengths at the parts of the connecting rod 42 on both sides of the identification member 41, that is, the distance from the first feedback member 43 to the identification member 41 will be greater than the distance from the identification member 41 to the hinge end of the connecting rod 42, thereby amplifying the movement stroke of the first feedback member 43 and improving the recognition accuracy. Preferably, the distance from the first feedback member 43 to the identification member 41 is five times the distance from the identification member 41 to the hinge end of the connecting rod 42.

[0054] Generally, workpieces 300 that are misaligned require correction. To this end, the conveyor channel 2 includes a correction station, and the transport assembly 3 is configured to transport the workpiece 300 to the correction station. The conveying mechanism capable of identifying and correcting the workpiece also includes a correction assembly 5 that rotates the workpiece 300 at the correction station. This arrangement allows the correction assembly 5 to rotate the corresponding workpiece 300 based on the recognition result of the recognition assembly 4, resulting in a high degree of automation and improved production efficiency.

[0055] Specifically, the correction assembly 5 includes a turntable 51 rotatably mounted on the frame 1 and a rotating member 52 for driving the turntable 51 to rotate. The turntable 51 is located at the correction station and is used to support the workpiece 300. It should be noted that the rotating member 52 can be any rotation drive structure in the prior art, such as a rotary cylinder, a servo motor, etc., and this embodiment does not impose any specific requirements or limitations on this.

[0056] In this embodiment, the transport assembly 3 includes a fork 31 and a power member 32. The fork 31 is provided with a transport groove 311 adapted to accommodate the workpiece 300. The power member 32 is used to drive the fork 31 in a predetermined direction. It is understood that by accommodating the workpiece 300 in the transport groove 311, the workpiece 300 can be minimized from deflecting during transport, facilitating subsequent identification and correction operations. It should be noted that the transport groove 311 only needs to be slightly larger than the workpiece 300 to ensure that it can effectively position the workpiece 300 without causing it to become stuck.

[0057] To further improve production efficiency, the loading station, identification station, correction station, and output station are arranged in sequence, equidistant along a preset direction. At least two transport troughs 311 are arranged equidistant along the preset direction. With this arrangement, the transport assembly 3 can simultaneously transport multiple workpieces 300, thereby simultaneously transporting multiple workpieces 300 to different stations. For example, while one workpiece 300 is being transported to the identification station, another workpiece 300 is being transported to the correction station. This ensures that the identification assembly 4 and the correction assembly 5 can operate simultaneously, thereby helping to improve production efficiency. In this embodiment, three transport troughs 311 are provided.

[0058] Generally, the loading mechanism of the next process equipment will be close to the previously mentioned output station. To prevent the shift fork 31 from impacting and damaging the loading mechanism of the next process equipment, in this embodiment, a buffer member 33 is provided on one side of the shift fork 31, away from the loading station. The buffer member 33 can abut against the frame 1 when the shift fork 31 passes the output station. Specifically, the buffer member 33 includes a contact block rotatably mounted on the end of the shift fork 31 and a torsion spring that resets the contact block.

[0059] To ensure the accuracy of the recognition results, the conveying mechanism capable of identifying and correcting the workpiece also includes a positioning assembly 6 disposed on the frame 1. The positioning assembly 6 is used to secure the workpiece 300 to a preset position on the recognition station. In this embodiment, the positioning assembly 6 includes an abutment 61 and a cylinder 62. The abutment 61 is disposed on the piston rod of the cylinder 62. The cylinder 62 can drive the abutment 61 to push against the workpiece 300 on the recognition station, so that the workpiece 300 remains in the preset position on the recognition station during the recognition process. In other embodiments, the cylinder 62 can also be replaced by other existing linear drive structures, such as a linear module, an electric cylinder, etc.

[0060] This embodiment further provides a loading device, which includes a vibrating plate 100 and the aforementioned conveying mechanism capable of identifying and correcting workpieces, wherein the conveying mechanism capable of identifying and correcting workpieces is used to convey the workpieces 300 supplied by the vibrating plate 100. It is understood that the loading device including the aforementioned conveying mechanism capable of identifying and correcting workpieces has low operating costs.

[0061] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
