Description

Technical Field

[0001] The present invention relates to an automatic feeding system, belonging to the technical field of automation equipment. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] During the automobile production process, a large number of door hinges need to be installed on the car body. In particular, different car models may use door hinges of different shapes. That is, the shape and structure of the door hinges vary, which increases the difficulty of loading the door hinges.

[0004] Although the assembly technology of door hinges is mature, the wide variety and different shapes of door hinges make it difficult to load them automatically. Therefore, the assembly system of door hinges has not yet been fully automated.

[0005] Furthermore, because traditional automatic material feeders struggle to automate the loading of door hinges, conventional loading is typically done manually, with workers placing the hinges directly into the assembly line fixtures. Manual loading requires constant vigilance, ensuring they avoid injury from the equipment, keep pace with the equipment, and avoid misplacing the wrong product. Furthermore, manual loading can be difficult to determine if a product's dimensions meet requirements. Utility Model Content

[0065] Unless otherwise stated, the exemplary embodiments / examples shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of the various embodiments / examples may be further combined, separated, interchanged, and / or rearranged without departing from the technical concepts of the present disclosure.

[0066] The use of cross hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise indicated, the presence or absence of cross hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the order described. In addition, the same figure numbers represent the same components.

[0067] When a component is referred to as being “on,” “over,” “connected to,” or “coupled to” another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another component, there are no intervening components present. For this purpose, the term “connected” may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0068] For descriptive purposes, the present disclosure may use spatially relative terms such as "below," "beneath," "under," "down," "above," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings.

[0070] Figure 1 It is a structural schematic diagram of an automatic loading system according to one embodiment of the present disclosure. Figure 2 It is a structural schematic diagram of an automatic loading system according to an embodiment of the present disclosure from another angle.

[0071] like Figure 1 and Figure 2 As shown, the automatic loading system of the present disclosure may include components such as a transmission device 100 , a material dividing device 200 , a material blocking device 300 and a handling device 400 .

[0072] Among them, the transmission device 100 is used to transmit the workpiece to be loaded, and the workpiece is transmitted from one end of the transmission device 100 to the other end of the transmission device 100; the dividing device 200 is arranged at the other end of the transmission device 100, for dividing the workpiece transmitted by the transmission device 100; the blocking device 300 is arranged at the other end of the transmission device 100, for blocking the workpiece after being divided by the dividing device 200, and so that there is a workpiece between the dividing device 200 and the blocking device 300; and the transporting device 400 is used to transport the workpiece blocked by the blocking device 300.

[0073] The structure of the automatic feeding system disclosed herein will be described in detail below with reference to the accompanying drawings.

[0074] Figure 3 It is a schematic structural diagram of a transmission device according to one embodiment of the present disclosure.

[0075] like Figure 3 As shown, the transmission device 100 of the present disclosure can be a belt conveyor, that is, the transmission device 100 transmits the workpiece from one end of the transmission device 100 to the other end through a conveyor belt. Accordingly, one end of the transmission device 100 is the feeding end, and the other end of the transmission device 100 can be the discharging end.

[0076] In the present disclosure, the transmission device 100 may include a base 101 and a driving device 102 disposed on the base 101. The driving device 102 may be a motor that can drive a driving roller to rotate. The driving roller is connected to a driven roller via a conveyor belt. In this case, the driving roller and the driven roller are both rotatably disposed on the base 101, and the driving roller and the driven roller are disposed parallel to each other and are both disposed horizontally, so that the upper surface of the conveyor belt can be located on a horizontal plane.

[0077] The conveying device 100 further includes a guide device 103 for guiding the workpieces conveyed on the conveyor belt. In a specific embodiment, the guide devices 103 are provided in pairs, and the two guide devices 103 are respectively arranged on both sides of the conveyor belt in the transmission direction. Thus, the workpieces conveyed on the conveyor belt can contact and be guided by the guide devices 103.

[0078] More preferably, the transmission device 100 also includes an adjusting device 104, which can adjust the distance between the two guide devices 103. Therefore, when the transmission device 100 of the present disclosure transmits workpieces of different sizes, the distance between the guide devices 103 can be adjusted to adapt to the size of the workpiece through the adjusting device 104, so that the transmission device 100 of the present disclosure can stably transport workpieces of different sizes.

[0079] In a specific embodiment, the adjustment device 104 can be a manual adjustment device, that is, the adjustment device 104 can include a screw and a handle connected to the screw. The screw can be rotatably mounted on the base 101 and its axial position is restricted by the base 101. The screw is provided with two nuts, which are respectively fixed to the two guide devices 103. Moreover, the screw is a double-rotating screw (or a bidirectional screw). Therefore, when the handle is turned to rotate the screw, the guide devices 103 can slide on the base 101, allowing the two guide devices 103 to move closer to or farther away from each other.

[0080] like Figure 2 As shown, a tool 110 is provided at one end of the transmission device 100 of the present disclosure. A contoured groove is provided on the tool 110 . After the workpiece passes through the contoured groove, it is transmitted by the transmission device 100 .

[0081] In a specific embodiment, a support frame 120 is provided at one end of the transmission device 100, and the support frame 120 is formed into a gantry structure, and a through groove is opened on the support frame 120 along the vertical direction and penetrates the support frame 120 from the vertical direction. At this time, the tooling 110 can be a plate-like structure, and the tooling 110 can be set in the through groove of the support frame 120, so that the automatic loading system disclosed in the present invention can easily replace the tooling 110.

[0082] When the automatic loading system of the present disclosure is in use, different tooling 110 can be selected according to different part shapes. At this time, the workpiece can be placed on the left side of the tooling 110 (in the form of a vertical bar) in a predetermined posture by manual or mechanical arms. Figure 2 The workpiece is then forced to the right by the tooling 110 (in the direction shown). The tooling 110 then moves to the conveyor belt, where it is then transported. The presence of the contoured groove effectively prevents products of varying sizes from flowing into the conveyor 100 and disrupting normal production cycles.

[0083] In addition, the workpiece can be changed by replacing different tooling 110. At this time, the distance between the guide devices 103 can be adjusted synchronously to meet the width requirement of the workpiece of this model.

[0084] In the present disclosure, the support frame 120 may also be provided with an identification device 130 capable of identifying the model of the tooling 110. In a specific embodiment, the identification device 130 may include multiple proximity sensors. Different tooling 110 may have holes at positions corresponding to the proximity sensors. These proximity sensors identify the model of the tooling 110 by identifying the positions of the holes in the tooling 110. Furthermore, after confirming the model of the tooling 110, the control system will know which workpiece will be transported and can change the control program accordingly to ensure the normal operation of the entire system.

[0085] Refer again Figure 3 In the present disclosure, the material dividing device 200 includes a material dividing cylinder 210 and a material dividing baffle 220 driven by the material dividing cylinder 210; wherein, the material dividing cylinder 210 is fixed to the other end of the transmission device 100, and the material dividing baffle 220 is used to block the upper end of the workpiece to achieve material dividing.

[0086] Specifically, the material distribution cylinder 210 can be fixed to the base 101 of the transmission device 100 via a bracket, and the material distribution cylinder 210 can drive the material distribution baffle 220 to cause the material distribution baffle 220 to move in the vertical direction. As a result, when the material distribution baffle 220 moves to its maximum downward position, it can block the movement of the workpiece, thereby achieving material distribution of the workpiece. Correspondingly, when the material distribution baffle 220 moves to its maximum upward position, the workpiece can pass under the material distribution baffle 220 without contacting the material distribution baffle 220.

[0087] Moreover, the material blocking device 300 includes a material blocking cylinder 310 and a material blocking baffle 320 driven by the material blocking cylinder 310; wherein, the material blocking cylinder 310 is fixed to the other end of the transmission device 100, and the material blocking baffle 320 is used to block the lower end of the workpiece to achieve material blocking.

[0088] Specifically, the material-blocking cylinder 310 can be fixed to the base 101 of the conveying device 100 via a bracket, and the material-blocking cylinder 310 can drive the material-blocking baffle 320 to cause the material-blocking baffle 320 to move in the vertical direction. Thus, when the material-blocking baffle 320 moves to its maximum upward position, it can block the movement of the workpiece, thereby achieving material blocking of the workpiece. Furthermore, when the material-blocking baffle 320 moves to its maximum downward position, the workpiece can be clamped and transported by the handling device 400 without contacting the material-blocking baffle 320.

[0089] In the present disclosure, the other end of the transmission device 100 is further provided with a first detection device 230, which can be a beam switch, and detects whether there is a workpiece between the feeding device 200 and the blocking device 300 through the first detection device 230; when there is a workpiece between the feeding device 200 and the blocking device 300, the transport device 400 can be activated to move the workpiece away, and at this time the feeding device 200 can prevent the movement of the transported workpiece, and the blocking device 300 moves to a position where it does not hinder the transport device 400. In another case, when there is no workpiece between the feeding device 200 and the blocking device 300, and after the transport device 400 leaves, the blocking device 300 is driven and located at the blocking position, and then the feeding device 200 is driven so that the workpiece passes through the feeding device 200 and is blocked by the blocking device 300. At this time, a new workpiece will flow between the feeding device 200 and the blocking device 300, and the next cycle can be carried out.

[0090] Moreover, a second detection device 330 can be provided on the material blocking baffle 320. The second detection device 330 can be a component such as a contact switch or a distance sensor. When the workpiece contacts the material blocking baffle 320, or there is a preset distance between the workpiece and the material blocking baffle 320, the second detection device 330 can be triggered, so that the position of the workpiece can be accurately known.

[0091] In a preferred embodiment, the automatic loading system further includes: a support member 500 , which is disposed at the other end of the transmission device 100 , and the workpiece located between the dividing device 200 and the blocking device 300 is supported by the support member 500 .

[0092] Figure 4 It is a schematic structural diagram of a transport device according to one embodiment of the present disclosure. Figure 5 It is a structural schematic diagram of a transport device according to an embodiment of the present disclosure from another angle.

[0093] like Figure 4 and Figure 5As shown, the handling device 400 of the present disclosure includes a moving platform 410 and a clamping jaw assembly 420 arranged on the moving platform 410. The clamping jaw assembly 420 includes a first clamping jaw 421 and a second clamping jaw 422. The first clamping jaw 421 and the second clamping jaw 422 approach or move away from each other in the up and down directions to clamp or release the workpiece.

[0094] Specifically, the motion platform 410 disclosed in the present invention can be a two-dimensional motion platform, which can have two degrees of freedom in the horizontal directions perpendicular to each other, and these two degrees of freedom in the horizontal directions perpendicular to each other can be driven separately by a driving device (such as a rodless cylinder), thereby realizing the movement of the jaw assembly 420, that is, realizing the movement of the jaw assembly 420 approaching and away from the workpiece, and realizing the movement stroke of the jaw assembly 420 for transporting the workpiece.

[0095] In the present disclosure, the first clamping jaw 421 (lower clamping jaw) includes two lower arms, and two grooves are opened on the support member 500, and the openings of the grooves face the transport device 400. When the clamping jaw assembly 420 clamps the workpiece, the two lower arms of the first clamping jaw 421 can be inserted into or removed from the grooves.

[0096] The second clamping jaw 422 (upper clamping jaw) includes two upper arms, each of which is provided with a pressing block 423 at one end. The pressing block 423 is used to press the workpiece against the lower arm, thereby achieving stable clamping of the workpiece.

[0097] In a preferred embodiment, the first clamping jaw 421 can be driven by a first clamping jaw driving cylinder and move in the vertical direction. The second clamping jaw 422 can be driven by a second clamping jaw driving cylinder and move in the vertical direction. Thus, the first clamping jaw 421 and the second clamping jaw 422 of the present disclosure can displace the workpiece in the vertical direction while holding it, thereby allowing the workpiece to be transported to different heights via the clamping jaw assembly 420.

[0098] Figure 6 2 is a schematic structural diagram of an inspection device 600 according to an embodiment of the present disclosure.

[0099] like Figure 6 As shown, the automatic loading system of the present disclosure further includes: an inspection device 600, which is used to receive the workpiece transported by the transport device 400 and inspect the workpiece.

[0100] Specifically, the inspection device 600 disclosed herein includes a limiting assembly 610 and a camera 620; wherein, the limiting assembly 610 is used to receive the workpiece transported by the transport device 400 and position the workpiece; the camera 620 is used to take pictures of the workpiece from above the workpiece, thereby realizing inspection of the workpiece.

[0101] More specifically, the inspection device 600 may include a workbench 630, on which a positioning seat 640 is provided, wherein the workpiece transported by the transport device 400 can be placed on the positioning seat 640. In addition, the present disclosure provides three position limiting assemblies 610, which respectively limit the workpiece in two directions.

[0102] In an optional embodiment, the limiting assembly 610 may include a limiting cylinder 611 and a limiting block 612. The limiting cylinder 611 can be set on the workbench 630, and the limiting block 612 can be slidably set on the positioning seat 640 so as to make pressure contact with the workpiece through the limiting block 612, so that the workpiece is stably held.

[0103] In a preferred embodiment, the camera 620 can be driven to move horizontally. Thus, the camera 620 can move from a position above the side of the workpiece to a position directly above the workpiece, and further, the camera 620 can move beyond the workpiece position to the other side of the workpiece. Thus, the camera 620 can perform an all-round inspection of the workpiece, thereby improving the accuracy of the inspection results.

[0104] The workpiece disclosed herein may be a door hinge. Generally speaking, door hinges are generally divided into two types, cast hinges and stamped hinges. The external dimensions of hinges produced by these two methods are difficult to be particularly precise. Automated production lines generally have high requirements for the accuracy of part dimensions. Moreover, since door hinges come in various shapes, the difficulty of automated assembly is undoubtedly increased. Although a door hinge is a small accessory, the assembly process is numerous and the cost of automated assembly equipment is high. Therefore, compatibility has become a rigid requirement for assembly equipment in factories. In other words, the automated assembly equipment needs to meet the assembly of hinges of different shapes as much as possible, so as to reduce equipment investment and significantly improve factory efficiency.

[0105] The automatic loading system disclosed in the present invention can be used as part of an automated assembly system to realize the transportation and inspection of door hinges. At the same time, qualified workpieces after inspection will be transported from the inspection device 600 to the automated assembly system by a robotic arm or other device. Moreover, the automatic loading system disclosed in the present invention is compatible with a variety of different products, can accurately identify each product, and can effectively pick and place. Therefore, the automatic loading system disclosed in the present invention reduces the workload of workers, meets production requirements, improves product qualification rate, and reduces labor intensity. Moreover, the automatic loading system disclosed in the present invention can also achieve the requirements of automated assembly in terms of technology, which can save a lot of manpower and time, reduce equipment investment, and greatly improve factory efficiency.

[0106] Specifically, when the automatic loading system disclosed in the present invention is in use, the workpieces can be manually placed to fill the entire transmission device. At this time, the worker can leave his post and handle other things. When part of the workpiece is consumed, he can continue to place products. Therefore, the automatic loading system disclosed in the present invention will not affect the production rhythm of the automated assembly line, and frees up manual time.

[0107] When the workpiece is placed on the positioning seat 640, two relatively arranged limiting assemblies 610 are actuated to clamp the workpiece. Then, the third limiting assembly 610 is actuated to push the workpiece straight from the side.
