[0002] A large number of SMD components are used in the production and processing of circuit boards. In order to ensure production efficiency, most of the existing SMD components are processed onto circuit boards by SMD machines. SMD components are usually strip materials, which are packaged in discs and need to be transported to the SMD machine through a feeder when loading.

[0003] The utility model patent with patent application publication number CN 211580532 U discloses a feeder assembly of a placement machine, including a feeder body, a material tray, a motor installed on the feeder body, a screw driven by the motor, a nut seat cooperating with the screw, a connecting rod connected to the nut seat, a transverse axis connected to the connecting rod, and a pressure cover; the free end of the transverse axis is provided with an external thread, the pressure cover is provided with a threaded hole, a screw sleeve is provided in the threaded hole, the pressure cover is screwed on the transverse axis, and the material tray is sleeved on the transverse axis and can rotate freely.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that although the setting of the pressure cover can effectively fix the material tray, when the material tray is disassembled and replaced, the operator needs to rotate and remove the pressure cover before removing the old material tray and installing the new one. During this process, the pressure cover and the connecting rod are always in a separated state, so it is easy to be lost. In addition, when resetting the pressure cover later, it is necessary to realign the pressure cover with the connecting rod, which poses a certain degree of operational difficulty.

[0005] Therefore, it is necessary to invent a feeder assembly for a placement machine to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a feeder assembly of a patch machine, which is provided with an avoidance locking mechanism so that when the material tray is disassembled, the adjusting handle is rotated in the opposite direction, and then the adjusting handle drives the conical push rod to move in the direction away from the rotating axis through the stud. At this time, the compressed reset spring drives the limit block to retract into the inside of the connecting sleeve, and then the material tray is pulled outward, so that the material tray is separated from the connecting sleeve and the outside of the adjusting handle, so as to solve the problem that although the setting of the pressure cover proposed in the above-mentioned background technology can effectively fix the material tray, when the material tray is disassembled and replaced, the operator needs to rotate and remove the pressure cover before removing the old material tray and installing the new material tray. During this process, the pressure cover and the connecting rod are always in a separated state, so it is easy to be lost. In addition, when the pressure cover is subsequently reset, it is necessary to realign the pressure cover with the connecting rod, which has a certain operating difficulty.

[0007] According to one aspect of the present disclosure, the following technical solution is provided: a feeder assembly of a placement machine, comprising:

[0008] A feeder body, wherein the feeder body is used to install the adjustment mechanism;

[0029] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.

[0032] 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 specified, 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 described order. In addition, the same figure numbers represent the same components.

[0033] When a component is referred to as being "on" or "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. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0034] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "down," "over," "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. For example, if the device in the accompanying drawings is turned over, components described as "under" or "beneath" other components or features would subsequently be positioned "over" the other components or features. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0035] The terms used here are for the purpose of describing specific embodiments, and are not intended to be restrictive. As used here, unless the context clearly indicates otherwise, the singular forms "one (kind, person)" and "said (the)" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, it is explained that there are stated features, integral bodies, steps, operations, parts, assemblies and / or their groups, but it is not excluded that there are or add one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups. It should also be noted that, as used here, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values ​​and / or the values ​​provided that will be recognized by those of ordinary skill in the art.

[0036] Figure 1 It is a schematic diagram of the overall structure of a feeder assembly of a placement machine according to an embodiment of the present disclosure.

[0037] like Figure 1-Figure 3 As shown, the feeder assembly of the placement machine disclosed in the present invention may include: a feeder body 1, an adjustment mechanism 2, an avoidance locking mechanism 3, a material tray 4 and other components.

[0038] Figure 2 It is a schematic structural diagram of an adjustment mechanism 2 of a gear pump sealing mechanism according to an embodiment of the present disclosure.

[0039] like Figure 2As shown, in the present disclosure, the adjusting mechanism 2 includes a driving motor 21, an adjusting screw 22, a moving slider 23, a moving rod 24, a connecting ring 25 and a rotating shaft 26, wherein the driving motor 21 is fixedly connected to the feeder body 1, the adjusting screw 22 is transmission-connected to the right side of the driving motor 21, the moving slider 23 is transmission-sleeved and arranged on the outside of the adjusting screw 22 and is slidingly fitted with the feeder body 1, the moving rod 24 is fixedly arranged at the bottom of the moving slider 23, the connecting ring 25 is fixedly arranged at the end of the moving rod 24, and the rotating shaft 26 is rotatably arranged on the inside of the connecting ring 25 through a bearing.

[0040] Therefore, when the driving motor 21 drives the adjusting screw 22 to rotate, the moving slider 23 moves left or right on the outside of the adjusting screw 22. During this process, the moving slider 23 drives the rotating shaft 26 to move left or right through the moving rod 24 and the connecting ring 25. When the rotating shaft 26 moves, it drives the avoidance locking mechanism 3 to move synchronously, thereby adapting to material trays 4 of different specifications.

[0041] Figure 3 It is a schematic structural diagram of an avoidance locking mechanism 3 of a gear pump sealing mechanism according to an embodiment of the present disclosure.

[0042] like Figure 3 As shown, in a preferred embodiment, the avoidance locking mechanism 3 includes a connecting sleeve 31, a limiting ring 32, a limiting block 33, a reset spring 34, a stud 35, a truncated cone-shaped push rod 36 and an adjusting handle 37, wherein the connecting sleeve 31 is fixedly connected to the rotating shaft 26, the limiting ring 32 is fixedly sleeved on the outside of the connecting sleeve 31, the limiting block 33 is slidably penetrated inside the connecting sleeve 31 and extends to the side of the connecting sleeve 31, the reset spring 34 is fixedly connected between the limiting block 33 and the inner wall of the connecting sleeve 31, the stud 35 is threadedly connected to the inside of the connecting sleeve 31, the truncated cone-shaped push rod 36 is fixedly arranged at the rear end of the stud 35, and the adjusting handle 37 is fixedly arranged at the front end of the stud 35.

[0043] Therefore, when installing the material tray 4, the material tray 4 is sleeved on the outside of the adjusting handle 37 and is continuously pushed, and the material tray 4 is continuously moved backward along the adjusting handle 37 and the connecting sleeve 31 until it is fitted with the limiting ring 32, and then the adjusting handle 37 is rotated, and the adjusting handle 37 drives the stud 35 to rotate continuously, and the rotation of the stud 35 drives the truncated cone-shaped push rod 36 to continuously move in the direction close to the rotating shaft 26. In this process, the truncated cone-shaped push rod 36 continuously pushes the limiting block 33, so that the limiting block 33 extends out from the inside of the connecting sleeve 31, and the extended limiting block 33 is fixed to the material tray 4 by the front of the material tray 4;

[0044] When disassembling the material tray 4, the adjusting handle 37 is rotated in the opposite direction, so that the adjusting handle 37 drives the conical push rod 36 to move away from the rotating shaft 26 through the stud 35. At this time, the compressed return spring 34 drives the limit block 33 to retract into the connecting sleeve 31, and then the material tray 4 is pulled outward, so that the material tray 4 can be separated from the connecting sleeve 31 and the outer side of the adjusting handle 37.

[0045] In the description of this specification, the description with reference to the terms "one embodiment / method", "some embodiments / methods", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment / method or example are included in at least one embodiment / method or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment / method or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments / methods or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments / methods or examples described in this specification and the features of different embodiments / methods or examples, unless they are contradictory.

[0046] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0047] Those skilled in the art should understand that the above embodiments are only for the purpose of clearly illustrating the present disclosure, and are not intended to limit the scope of the present disclosure. For those skilled in the art, other changes or modifications may be made based on the above disclosure, and these changes or modifications are still within the scope of the present disclosure.
