Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of manufacturing equipment for electrical components and assemblies, specifically relating to component supply equipment, and more particularly to an inverted feeder for SMT material supply. Background Technology
[0002] Surface Mount Technology (SMT) is a commonly used assembly technology and process in the current electronic equipment manufacturing industry.
[0003] In the surface mount technology (SMT) process, a strip material is required. The strip material is placed on a reel and continuously pulled out until it is used up and then replaced. In order to improve the operating efficiency of the production line, a special strip changing mechanism needs to be designed to replace the strip material on the reel during the continuous conveying of the strip material.
[0004] In related technologies, the buffer bin of the tape-changing mechanism is generally located below the conveyor mechanism (such as the SMT material feeding connection bin device and its feeding method provided in publication number CN119155983A). Redundant tape is buffered in the buffer bin by gravity. However, the inventors found that this method easily leads to the tape layers tangling and stacking, forming a disordered state. During subsequent conveying, tape knots and creases are likely to occur, and in more severe cases, tape knots may occur, affecting tape usage. Furthermore, due to limited space, the lower-positioned buffer bin affects the size of the waste bin located below it, thus impacting the continuity of tape usage.
[0005] Therefore, how to avoid the entanglement and stacking of the material strip caused by using gravity to buffer the material strip, while reducing the impact on the size of the waste bin, is a technical problem that urgently needs to be solved.
[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

Simultaneously, the buffer bin's location above the conveyor mechanism reduces the space occupied by the waste bin, further ensuring the stable operation of the SMT production line.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0054] In this document, when it is mentioned that a first component is located on a second component, this can mean that the first component can be directly formed on the second component, or that a third component can be inserted between the first and second components. Furthermore, in the accompanying drawings, the thickness of the components may be exaggerated or reduced for the purpose of effectively describing the technical content.
[0055] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.
[0056] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list. For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.
[0057] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting.

Rather, the use of the terms “example,” “exemplary,” etc., is intended to present concepts in a specific manner.
[0059] Research has found that the buffer bins of the tape changing mechanism in related technologies are generally located below the conveyor mechanism. By using gravity to buffer redundant tapes into the buffer bins, it is easy for the tape layers to become entangled and stacked, forming a disordered state. As a result, when used for SMT assembly, the tapes are prone to knots and creases, affecting the stable operation of the SMT production line.
[0060] Based on the above research, this disclosure provides an inverted feeder bin for SMT material supply. By inverting the buffer bin 200 above the conveyor mechanism 300 and coordinating with the adsorption effect of the negative pressure adsorption block 210, active adsorption force replaces passive gravity, forcing the material tape 400 to be contained into the buffer bin 200 and straightened. This completely avoids the material tape 400 from freely stacking under the action of gravity, allowing the material tape 400 to be stored orderly in the buffer bin 200, thus ensuring the stable operation of the SMT production line.
[0061] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.
[0062] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0063] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0064] Please see Figure 1 and Figure 2 At least one embodiment provides an inverted feeder for SMT materials, comprising: a side plate 100; a buffer 200 disposed on the side plate 100; and a conveying mechanism 300 disposed on the side plate 100 and located below the buffer 200; wherein, a feed inlet 220 is provided at the bottom of the buffer 200; and a negative pressure adsorption block 210 is provided at the top of the buffer 200; during feeder connection, an external negative pressure source provides adsorption force to the buffer 200 through the negative pressure adsorption block 210 to feed the material strip 400 located at the feed inlet 220 into the buffer 200.
[0065] By inverting the buffer bin 200 above the conveyor mechanism 300 and coordinating the suction effect of the negative pressure adsorption block 210, active adsorption force replaces passive gravity, forcing the material tape 400 into the buffer bin 200 and straightening it. This completely prevents the material tape 400 from freely stacking under gravity, ensuring that the material tape 400 is stored orderly within the buffer bin 200. This fundamentally solves the problems of material tape 400 entanglement, stacking, knotting, and creases, significantly improving buffer orderliness and material supply continuity, and ensuring the stable operation of the SMT production line. Simultaneously, the buffer bin's location above the conveyor mechanism reduces the space occupied by the waste bin, further ensuring the stable operation of the SMT production line.
[0066] It should be noted that the conveyor mechanism 300 will guide the material belt 400 along... Figure 2 The conveyor belt 400 is conveyed in the direction shown in F4 to taut it. Simultaneously, an external negative pressure source provides suction force to the buffer chamber 200 through the negative pressure adsorption block 210, adsorbing the conveyor belt 400 at the inlet 220 and causing it to move along... Figure 2 The data is sent to the cache bin 200 in the direction indicated by F5.
[0067] Please continue reading. Figure 1 and Figure 2 The buffer compartment 200 includes: a side cover 240, which covers the side plate 100; the bottom of the side cover 240 has a notch to form a feed inlet 220; and a sealing member 250, which is disposed between the side cover 240 and the side plate 100 to seal the side cover 240 and the side plate 100 to maintain the adsorption force inside the buffer compartment 200.
[0068] The sealing element 250 ensures stable negative pressure inside the buffer chamber 200 and avoids fluctuations in adsorption force. The sealing element 250 is a sealing strip, which is set along the closing part of the side cover 240 to complete the sealing of the buffer chamber 200.
[0069] Please see Figure 1 and Figure 2 The buffer bin 200 is also equipped with a hopper detection sensor 500 to detect the material strip 400 in the buffer bin 200.
[0070] Specifically, the hopper detection sensor 500 includes a sensor positioned near the feed inlet 220.
[0071] By placing the hopper detection sensor 500 close to the feed inlet 220, it is possible to promptly determine the presence or absence of material in the buffer bin 200.
[0072] Please see Figure 1 and Figure 3 The conveying mechanism 300 includes: a roll-changing end drive unit 310 and a connecting end drive unit 320, wherein the roll-changing end drive unit 310 and the connecting end drive unit 320 are respectively disposed at both ends of the side plate 100 and located below the feed inlet 220 of the buffer bin 200; and a feeding drive unit 330, which is disposed between the roll-changing end drive unit 310 and the connecting end drive unit 320, located directly below the feed inlet 220, and is used to feed the material belt 400 into the feed inlet 220 of the buffer bin 200.
[0073] Specifically, the two ends of the tape 400 are handled by the roll-changing end drive unit 310 and the docking end drive unit 320, respectively. The feeding drive unit 330 is responsible for vertically feeding the tape 400 into the buffer bin 200. The feeding drive unit 330 feeds the tape 400 into the feed inlet 220 of the buffer bin 200, thereby avoiding the tape 400 from accumulating below the feed inlet 220 and ensuring that the redundant tape 400 is efficiently transferred to the inverted buffer bin 200.
[0074] Please continue reading. Figure 1 and Figure 3The connecting end drive unit 320 includes: a first fixed driven wheel 321, which is disposed on the side plate 100; and a first moving drive wheel 322, which is disposed on the side plate 100 through a first lifting module 323 and driven by a first drive motor 324.
[0075] Specifically, the first driving wheel 322 along Figure 2 Rotate in the direction shown by F6 to convey the redundant material belt 400 after docking toward the feeding drive unit 330.
[0076] Please continue reading. Figure 1 and Figure 3 The feeding drive unit 330 includes: a first clamping wheel 331, which is mounted on the side plate 100 via a second lifting module 333; and a second clamping wheel 332, which is mounted on the side plate 100 via a third lifting module 334. The first clamping wheel 331 and the second clamping wheel 332 are both located directly below the feed inlet 220, and the first clamping wheel 331 is located above the second clamping wheel 332. A guide plate 3321 is provided on the side of the second clamping wheel 332 to guide the material belt 400.
[0077] The first clamping wheel 331 is driven by the second drive motor 335, and the first clamping wheel 331 moves along... Figure 2 Rotate in the direction shown by F3 to feed the tape 400 that will be retracted from the connecting end drive unit 320 into the buffer bin 200.
[0078] Please continue reading. Figure 1 and Figure 3 The roll-changing end drive unit 310 includes: a second fixed driven wheel 311, which is disposed on the side plate 100; and a second moving drive wheel 312, which is disposed on the side plate 100 through a fourth lifting module 313 and driven by a third drive motor 314.
[0079] It should be noted that the first lifting module 323, the second lifting module 333, the third lifting module 334 and the fourth lifting module 313 are all located on the back of the side plate 100, that is, on the other side of the buffer compartment 200, and are all driven by a cylinder and a slider.
[0080] Please see Figure 2 and Figure 4The conveying mechanism 300 further includes: a trigger 340, which is disposed on the side of the connecting end drive 320 away from the changing end drive 310; the trigger 340 includes: a mounting block 341, which is disposed below the side plate 100; a rotating arm 342, which is rotatably connected to the mounting block 341 via a rotating shaft 3411; and a holding rod 343, one end of which is connected to the rotating arm 342 and the other end of which extends into the lower end of the material belt 400; wherein, an elastic trigger rod 344 is disposed below the rotating arm 342 and a detection sensor 345 is disposed below the mounting block 341. When the material belt 400 is taut, the holding rod 343 is pressed down, thereby driving the rotating arm 342 to rotate downward so that the elastic trigger rod 344 approaches the detection sensor 345.
[0081] Because the top of the elastic trigger rod 344 abuts against the rotating arm 342, when the material belt 400 is taut, the material belt 400 presses down against the abutment rod 343 as follows. Figure 2 The movement of F1 causes the rotating arm 342 to rotate downwards, and the elastic trigger rod 344 moves along... Figure 2 The material moves in the F2 direction and approaches the detection sensor 345. The detection sensor 345 provides real-time feedback on the tautness of the material belt 400, thereby confirming whether the redundant material belt 400 has been completely fed into the buffer bin 200.
[0082] Please see Figure 2 and Figure 4 The end of the abutment rod 343 away from the rotating arm 342 is provided with a guide rod 346; the guide rod 346 is inclined outward to guide the material strip 400 placed above the abutment rod 343.
[0083] When the material strip 400 is inserted, it automatically slides along the guide bar 346 above the holding bar 343, preventing the redundant material strip 400 from slipping off the holding bar 343 during buffering.
[0084] Please see Figure 2 Two auxiliary guide wheels 110 are also provided on both sides of the feed inlet 220; when the material belt 400 rises with the first clamping wheel 331 and the second clamping wheel 332, the material belt 400 abuts against the bottom of the auxiliary guide wheels 110 on both sides of the feed inlet 220.
[0085] Please continue reading. Figure 2 A feed detection sensor 600 is provided at the drive unit 310 at the roll changing end to detect the presence or absence of the material belt at the roll changing end.
[0086] In summary, this utility model provides an inverted feeder for SMT materials, comprising: a side plate 100; a buffer 200 disposed on the side plate 100; and a conveying mechanism 300 disposed on the side plate 100 and located below the buffer 200. The buffer 200 has a feed inlet 220 at its bottom and a negative pressure adsorption block 210 at its top. During feed, an external negative pressure source provides adsorption force to the buffer 200 through the negative pressure adsorption block 210, thereby feeding the material strip 400 located at the feed inlet 220 into the buffer 200. By inverting the buffer bin 200 above the conveyor mechanism 300 and coordinating the suction effect of the negative pressure adsorption block 210, active adsorption force replaces passive gravity, forcing the material tape 400 into the buffer bin 200 and straightening it. This completely prevents the material tape 400 from freely stacking under gravity, ensuring that the material tape 400 is stored orderly within the buffer bin 200. This fundamentally solves the problems of material tape 400 entanglement, stacking, knotting, and creases, significantly improving buffer orderliness and material supply continuity, and ensuring the stable operation of the SMT production line. Simultaneously, the buffer bin's location above the conveyor mechanism reduces the space occupied by the waste bin, further ensuring the stable operation of the SMT production line.
[0087] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0088] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein.

[0089] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation.

Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0090] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
