Description

Technical Field

[0001] The utility model relates to the field of mechanical engineering, in particular to a feeding mechanism, and a feeding device and a detection device comprising the same. Background Art

[0002] In automated production lines, belt conveyors often transport items (products or raw materials) from one workstation to the next. Items need to stop at each workstation to facilitate processing. Currently, this is achieved by controlling the start and stop of the belt conveyor. However, this repeated start and stop behavior results in low conveying efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a feeding mechanism, which is beneficial to improving the conveying efficiency.

[0004] Another object of the present invention is to provide a feeding device, the feeding mechanism of which is conducive to improving the conveying efficiency.

[0005] Another object of the present invention is to provide a detection device whose feeding mechanism is conducive to improving the conveying efficiency.

[0006] The utility model provides a feeding mechanism comprising a bracket and a feeding unit. The feeding unit comprises a belt conveyor assembly and a lifting frame. The belt conveyor assembly is mounted on the bracket and comprises a conveyor belt and rollers supporting the conveyor belt. The conveyor belt comprises at least two supporting segments extending along a trajectory parallel to the conveying direction. The at least two supporting segments are spaced apart along the conveying direction. A clearance gap is formed between each two adjacent supporting segments. The supporting segments are capable of supporting articles in a supporting direction perpendicular to the conveying direction. The conveyor belt further comprises at least one connecting segment. Each connecting segment connects two adjacent supporting segments and arches in a direction opposite to the supporting direction. The lifting frame comprises at least one supporting arm. Each supporting arm is opposite to a clearance gap in the supporting direction and is located on the side of the corresponding connecting segment pointing in the supporting direction. The lifting frame is movably connected to the bracket in the supporting direction and in a direction opposite to the supporting direction, thereby driving the supporting arm to move between a retracted position and a lifting position. When the supporting arm moves from the retracted position to the lifting position along the supporting direction, the supporting arm passes through the clearance and lifts the article supported by the supporting section along the supporting direction.

[0007] The feeding mechanism is beneficial to improving the conveying efficiency.

[0008] In another exemplary embodiment of the feeding mechanism, the lifting frame further comprises a lifting body. The lifting body is disposed on one side of the belt conveyor assembly along the width direction, wherein the width direction is perpendicular to the conveying direction and the supporting direction. The lifting body is movably connected to the bracket in the supporting direction and in a direction opposite to the supporting direction. A supporting arm extends in a direction parallel to the width direction, with one end fixedly connected to the lifting body and the other end freely disposed and used to lift the object. This structure is simple and easy to manufacture.

[0009] In another exemplary embodiment of the feeding mechanism, the feeding mechanism is provided with two feeding units. The belt conveyor assemblies of the two feeding units are arranged side by side in the width direction to respectively support the widthwise edges of the articles. For each feeding unit, the lifting body of the support frame is arranged on the side of the belt conveyor assembly facing away from the other feeding unit in the width direction. This helps to improve the stability of the supported articles.

[0010] In another exemplary embodiment of the feeding mechanism, the free end of the support arm has a holding slot. The holding slot is defined by a supporting surface and a stop surface, both perpendicular to each other. The supporting surface is perpendicular to and oriented in the same direction as the supporting direction. The stop surface faces the other feeding unit. This helps prevent widthwise displacement or skew of the items held by the support arm.

[0011] In another exemplary embodiment of the feeding mechanism, each feeding unit includes several limit blocks. Several limit blocks are fixedly connected to the bracket and are arranged at intervals along the conveying direction. Each limit block is opposite to a supporting section along the width direction. The gap between each two adjacent limit blocks is opposite to a clearance gap along the width direction. Each limit block has a limit groove. The limit groove is defined by a first limit surface and a second limit surface that are perpendicular to each other. The first limit surface is perpendicular to the supporting direction and faces the same direction as the supporting direction. The second limit surface faces the other feeding unit. The supporting section is arranged in the limit groove of the corresponding limit block. For each feeding unit, the lifting body of the lifting frame is arranged on the side of the several limit blocks that is away from the other feeding unit along the width direction. The support arm can pass through the gap between two adjacent limit blocks during movement. This helps to improve the stability of the belt conveyor assembly in conveying items.

[0012] In another exemplary embodiment of a feeding mechanism, the bracket includes a base, a first frame, and a second frame. The first frame and the second frame are connected to the base, and at least one of the first frame and the second frame is adjustable in width relative to the base. Two feeding units are mounted on the first frame and the second frame, respectively. By adjusting the width distance between the first frame and the second frame, the feeding mechanism can be adapted to accommodate items of various sizes. This improves the adaptability of the feeding mechanism.

[0013] In another exemplary embodiment of the feeding mechanism, at least one of the first and second frames is movably connected to the base in the width direction and in a direction opposite to the width direction. The bracket further includes a ball screw structure. The axial direction of the ball screw structure is parallel to the width direction. The screw of the ball screw structure is rotatably connected to the base about its axis. The nut of each ball screw structure is fixedly connected to the one of the first and second frames that is movably connected to the base. This facilitates adjustment of the distance between the first and second frames in the width direction.

[0014] The present invention also provides a loading device comprising the aforementioned feeding mechanism and a robotic arm. The robotic arm is capable of gripping an article held up by the supporting arm in a lifting position. The feeding mechanism of the loading device improves conveying efficiency, thereby improving the operating efficiency of the loading device.

[0015] The present invention also provides a detection device comprising several of the aforementioned feeding devices and several detection units. The feeding devices are arranged along the conveying direction so that the belt conveyor assemblies of the feeding devices can continuously convey items along the conveying direction. Each feeding device corresponds to at least one detection unit, and each detection unit corresponds to at least one feeding device. The robotic arm of each feeding device can deliver the items it has gripped to the corresponding detection unit. The detection unit is used to detect the received items. The feeding mechanism of the detection device helps improve the conveying efficiency, thereby improving the working efficiency of the detection device.

[0016] In another exemplary embodiment of the inspection equipment, a belt conveyor assembly comprising several loading devices forms a conveyor chain. The inspection equipment also includes a feeding device and a diverter. The feeding device is capable of moving items to the starting point of the conveyor chain. The diverter receives items from the end point of the conveyor chain and transports them to multiple locations. This provides a structural foundation for automated inspection and sorting.

[0061] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings. The same reference numerals in the figures represent components with the same structure or similar structures but the same functions.

[0062] In this document, “illustrative” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “illustrative” should not be interpreted as a more preferred or more advantageous technical solution.

[0063] In this article, "first", "second", etc. do not indicate their importance or order, but are only used to indicate the difference between each other for the convenience of document description.

[0064] To simplify the drawings, each figure schematically shows only the parts related to the present invention, which do not represent the actual structure of the product.

[0065] Figure 1 The figure is a perspective view of a schematic embodiment of a feeding mechanism. The feeding mechanism is used to transport objects, such as circuit boards, but not limited thereto. Figure 1 As shown, the feeding mechanism 100 includes a bracket 10 and two feeding units 20. Each feeding unit 20 includes a belt conveyor assembly 21 and a lifting frame 23.

[0066] Each belt conveyor assembly 21 is mounted on the bracket 10 and includes a conveyor belt 211 (for clarity, Figure 1 The middle conveyor belt 211 is drawn with a dotted line) and 13 rollers 212 supporting the conveyor belt 211 ( Figure 1 Only one of the rollers 212 is schematically shown. The belt conveyor assemblies 21 of the two feeding units 20 are arranged side by side along the width direction W to support the two side edges of the article along the width direction W respectively.

[0067] Figure 2 Shows Figure 1 The belt conveyor assembly of the feeding mechanism shown in FIG. Figure 2 As shown, the conveyor belt 211 includes four supporting segments Dt extending along a trajectory line L parallel to the conveying direction S, wherein the conveying direction S is perpendicular to the width direction W. The four supporting segments Dt are arranged at intervals along the conveying direction S. A clearance gap G is formed between each two adjacent supporting segments Dt. The supporting segments Dt can support items along a supporting direction T perpendicular to the conveying direction S and the width direction W. The conveyor belt 211 also includes three connecting segments Dx. Each connecting segment Dx connects two adjacent supporting segments Dt and arches in the opposite direction of the supporting direction T. The belt conveyor assembly 21 can transport the items supported by the supporting segments Dt along the conveying direction S or the opposite direction of the conveying direction S. The belt conveyor assembly 21 can be started by driving one of the rollers 212 to rotate by a motor.

[0068] like Figure 1 and Figure 2 As shown, each support frame 23 includes three support arms 231. The three support arms 231 are arranged along the conveying direction S. Each support arm 231 is opposite a clearance gap G along the supporting direction T and is located on the directional side of the corresponding connecting section Dx along the supporting direction T (i.e., the upper side in the figure). The support frame 23 is movably connected to the bracket 10 along the supporting direction T and the direction opposite to the supporting direction T, thereby driving the support arms 231 to move between a retracted position and a supporting position. Figure 1 and Figure 2 In the embodiment, the support arm 231 is in the retracted position. In this case, the object supported by the supporting segment Dt is located above the support arm 231 and does not contact the support arm 231. During the movement of the support arm 231 from the retracted position to the lifting position along the supporting direction T, the support arm 231 passes through the clearance G and lifts the object supported by the supporting segment Dt along the supporting direction T. Figure 3 The state after the supporting arm 231 reaches the lifting position is shown. Figure 4 and Figure 5 The position of the article 90 on the feeding mechanism 100 when the supporting arm 231 is in the retracted position and the supporting position is shown from the side. Figure 4 The article 90 is supported on the supporting section Dt of the conveyor belt 211. Figure 5 The middle article 90 is lifted upward by the supporting arms 231 of the two lifting frames 23 and separated from the conveyor belt 211 .

[0069] When the supporting arms 231 are in the retracted position, the items supported by the conveyor belt 211 can be moved along the conveying direction S or the opposite direction of the conveying direction S by the conveyor belt 211. When the items are conveyed by the conveyor belt 211 to above the supporting arms 231, the lifting frame 23, which moves upward along the supporting direction T, can lift the items supported by the conveyor belt 211 along the supporting direction T via the supporting arms 231, removing them from the conveyor belt 211. In this way, the items lifted by the lifting frame 23 remain at their current position, while the belt conveyor assembly 21 can continue to convey other items, thereby improving conveying efficiency.

[0070] In other schematic embodiments of the feeding mechanism, the number of feeding units 20 of the feeding mechanism, the number of lifting frames 23 of each feeding unit 20, the number of supporting arms 231 of each lifting frame 23, the number of supporting sections Dt and connecting sections Dx of each conveyor belt 211, and the number of rollers 212 of each belt conveyor assembly 21 can all be adjusted as needed.

[0071] Figure 6 It is a structural diagram of the lifting frame. Figure 1 and Figure 6 As shown, in the schematic embodiment, the lifting frame 23 also includes a lifting body 232. For each feeding unit 20, the lifting body 232 of the lifting frame 23 is arranged on the side of the belt conveyor assembly 21 away from the other feeding unit 20 along the width direction W, thereby helping to avoid the lifting frame 23 from interfering with the conveying of items by the conveyor belt 211. The lifting body 232 is movably connected to the bracket 10 along the supporting direction T and the opposite direction of the supporting direction T. Specifically, the lifting body 232 includes, for example, a lifting rod. The lifting rod is movably provided in the bracket 10 along the supporting direction T and the opposite direction of the supporting direction T. The support arm 231 extends in a direction parallel to the width direction W and is fixedly connected to the lifting body 232 at one end, and the other end is freely arranged and used to lift items. This structure is simple and has good stability.

[0072] like Figure 6 As shown, in the exemplary embodiment, the free end of the supporting arm 231 has a holding groove C1. The holding groove C1 is defined by a supporting surface Ft and a stop surface Fd that are perpendicular to each other. The supporting surface Ft is perpendicular to the supporting direction T and faces the same direction as the supporting direction T. The supporting surface Ft is used to support items along the supporting direction T. The stop surface Fd faces the other feeding unit 20. The stop surface Fd is used to support the items held by the supporting surface Ft of the supporting arm 231 in a direction parallel to the width direction W, so as to prevent the items from shifting or skewing in the width direction W.

[0073] like Figure 1 and Figure 3As shown, in the exemplary embodiment, each feed unit 20 includes four stoppers 25. The four stoppers 25 are fixedly connected to the bracket 10 and spaced apart along the conveying direction S. Each stopper 25 is aligned with a support segment Dt along the width direction W. The gap between each two adjacent stoppers 25 is aligned with a clearance gap G along the width direction W.

[0074] Figure 7 Used to display the three-dimensional structure of the limit block. Figure 7 As shown, each limiting block 25 has a limiting groove C2. The limiting groove C2 is defined by a first limiting surface F1 and a second limiting surface F2, which are perpendicular to each other. The first limiting surface F1 is perpendicular to the supporting direction T and faces the same direction as the supporting direction T. The second limiting surface F2 faces the other feeding unit 20. The supporting section Dt is arranged in the limiting groove C2 of the corresponding limiting block 25. Ideally, the supporting section Dt maintains a set distance from the first limiting surface F1. The first limiting surface F1 can prevent the supporting section Dt from excessively collapsing during use. The second limiting surface F2 is used to prevent the articles supported by the conveyor belt 211 from shifting or skewing in the width direction W during the conveying process. This helps to improve the stability of the belt conveyor assembly 21 in conveying articles. For each feeding unit 20, the lifting body 232 of the lifting frame 23 is arranged on the side of the four limiting blocks 25 along the width direction W away from the other feeding unit 20. The supporting arm 231 can pass through the gap between two adjacent limiting blocks 25 during the movement.

[0075] like Figure 1 As shown, in the schematic embodiment, the bracket 10 includes a base 11, a first frame 13 and a second frame 15. The second frame 15 is fixedly connected to the base 11, and the position of the first frame 13 relative to the base 11 along the width direction W is adjustable. Specifically, the first frame 13 is movably connected to the base 11 along the width direction W and the opposite direction of the width direction W. The first frame 13 is movably connected to the base 11 by a sliding rod fixed to the second frame 15, for example, by a sliding connection, but is not limited to this. Two feeding units 20 are respectively installed on the first frame 13 and the second frame 15. By adjusting the distance between the first frame 13 and the second frame 15 along the width direction W, the feeding mechanism can be adapted to items of various sizes. This helps to improve the applicability of the feeding mechanism. In other schematic embodiments, the positions of the first frame 13 and the second frame 15 relative to the base 11 along the width direction W can be adjusted.

[0076] like Figure 1As shown, in the exemplary embodiment, the bracket 10 further includes a ball screw structure 17. The axial direction of the ball screw structure 17 is parallel to the width direction W. The screw of the ball screw structure 17 is rotatably connected to the base 11 around its axis. In this exemplary embodiment, the second frame 15 is fixedly connected to the base 11, and the screw of the ball screw structure 17 is indirectly connected to the base 11 by being rotatably connected to the second frame 15. The nut of the ball screw structure 17 is fixedly connected to the first frame 13. This facilitates adjustment of the distance between the first frame 13 and the second frame 15 along the width direction W.

[0077] In the exemplary embodiment, the feeding mechanism further comprises, for example, a motor for driving the belt conveyor assembly 21 and a cylinder for driving the lifting frame 23. The feeding mechanism further comprises, for example, a programmable logic controller for signal connection between the motor and the cylinder.

[0078] Figure 8 FIG. 1 is a schematic structural diagram of a schematic embodiment of a feeding device. Figure 8 As shown, the loading device 1000 includes a Figure 1 The feeding mechanism 100 shown is a mechanical arm 200. The mechanical arm 200 can clamp the articles held up by the supporting arm 231 in the lifting position. The feeding mechanism of the feeding device is conducive to improving the conveying efficiency, thereby helping to improve the working efficiency of the feeding device.

[0079] In other exemplary embodiments, the number of the feeding mechanisms 100 and the robotic arms 200 of the loading device can be adjusted as needed.

[0080] Figure 9 FIG. 1 is a schematic structural diagram of a schematic embodiment of a detection device. Figure 9 As shown, the detection equipment includes two Figure 8 The feeding device 1000 and two detection units 2000 are shown. The two feeding devices are arranged along the conveying direction S so that the belt conveyor assemblies 21 of the two feeding devices can continuously convey items along the conveying direction S. Each feeding device corresponds to a detection unit 2000. The robotic arm 200 of each feeding device can deliver the items it clamps to the corresponding detection unit 2000. The detection unit 2000 is used to detect the received items, and the detection is, for example, a circuit board ICT test (In-Circuit Test) or a circuit board FCT test (Functional Circuit Test), but is not limited to this. The feeding mechanism of the detection equipment is conducive to improving the conveying efficiency, thereby helping to improve the working efficiency of the detection equipment.

[0081] In other exemplary embodiments, the number of the loading devices 1000 and the number of the detection units 2000 of the detection equipment can be adjusted as needed.

[0082] like Figure 9 As shown, in the schematic embodiment, the belt conveyor assembly of the two feeding devices forms a conveyor chain. The detection equipment also includes a feeding device 3000 and a diverter device 4000. The feeding device 3000 is capable of moving the items to the starting point of the conveyor chain. The diverter device 4000 is capable of receiving items from the end point of the conveyor chain and transporting the received items to multiple locations. When in use, for example, the diverter device 4000 is controlled to transport the items to different locations based on different detection results of the detection unit 2000. This provides a structural basis for automated detection and classification.
