Abstract
Description
Technical Field
[0001] This disclosure relates to a multi-station unloading mechanism, belonging to the field of automation equipment technology. Background Technology
[0002] With technological advancements, more and more factories are adopting automated equipment to manufacture products. This is especially true in the production of 3C products, where automated equipment has become widespread.
[0003] In the process of product manufacturing using automated equipment, the automation of loading and unloading is one of the important factors affecting the efficiency of automated equipment. During the loading and unloading of some materials, due to the different spacing between the cavities in the material trays, or when moving materials from a large material tray to a small material tray, there are situations where the spacing between the materials during picking up is different from that during unloading; in addition, in some cases, the placement direction of the materials also differs between different material trays.
[0004] Currently, many devices use a single-pick-and-place method to handle this problem. While this method is highly stable, it can only pick up 1-2 materials at a time, resulting in extremely low efficiency and severely impacting the equipment's production cycle. In this automated environment that demands high stability and efficiency, this operating method has become a key factor affecting production efficiency. Utility Model Content

[0043] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.
[0044] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0045] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.
[0046] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.
[0047] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.
[0048] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0049] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values that would be recognized by one of ordinary skill in the art.
[0050] Figure 1 This is a structural schematic diagram of a multi-station unloading mechanism 800 according to one embodiment of the present disclosure.
[0051] like Figure 1 As shown, the multi-station unloading mechanism 800 of this disclosure, when in use, enables materials to be unloaded from an automated production line at varying distances, or enables materials to be transferred from one pallet to another at varying distances.
[0052] The multi-station unloading mechanism 800 disclosed herein may include components such as a motion platform 810, a pitch changing device 820, and an unloading module 830.
[0053] The motion platform 810 is configured to move along a first direction; wherein, the first direction may be horizontal. In a specific embodiment, the motion platform 810 is a motor-driven lead screw and nut structure. Since the motor-driven lead screw and nut structure is a common structure in the art, its structure will not be described in detail here.
[0054] The pitch-changing device 820 is disposed on the motion platform 810, and the motion platform 810 drives the pitch-changing device 820 to reciprocate along the first direction; thus, when the multi-station unloading mechanism 800 of this disclosure is in use, it can not only change the distance between materials, but also make the materials move as a whole along the first direction.
[0055] In one specific embodiment, the pitch control device 820 is a motor-driven cam pitch control mechanism.
[0056] Figure 3 This is a schematic diagram of the motion platform and pitch-changing device of a multi-station unloading mechanism according to one embodiment of the present disclosure. Figure 4 This is a structural schematic diagram of the motion platform and pitch-changing device of a multi-station unloading mechanism according to one embodiment of the present disclosure from another angle.
[0057] like Figure 3 and Figure 4 As shown, the pitch-changing device 820 of this disclosure includes a housing 821, on which a plurality of guide rails 822 are disposed, wherein the plurality of guide rails 822 are all arranged along a first direction. Specifically, one surface of the housing 821 of this disclosure is disposed substantially vertically, and a through hole is formed on the surface, the through hole extending along the first direction. At the same time, the camshaft of the pitch-changing device 820 also extends along the first direction, and the camshaft corresponds to the through hole in the height direction.
[0058] The pitch control device 820 disclosed herein also includes a pitch block 823, wherein the pitch block 823 can be driven by a camshaft to change the distance in a first direction. That is, at least a portion of the pitch block 823 can be inserted into the interior of the housing 821 via a through hole, thereby allowing the portion of the pitch block 823 located within the housing 821 to slide within a cam groove on the camshaft, thus enabling the pitch block 823 to change position in the first direction.
[0059] See again Figure 1 The material feeding module 830 of this disclosure is configured as a plurality of modules, wherein the pitch changing device 820 is used to drive the plurality of material feeding modules 830 to operate so that the distance between adjacent material feeding modules 830 can be changed.
[0060] In other words, the number of pitch blocks 823 disclosed herein can be the same as the number of unloading modules 830 and they can be set one-to-one. Thus, when the pitch blocks 823 move in the first direction, the unloading modules 830 can move in the first direction.
[0061] The blanking module 830 is provided with a slider 824; specifically, the blanking module 830 of this disclosure is not directly connected to the slider 824, but is indirectly connected to the slider 824. For example, the blanking module 830 can be connected to the pitch block 823 through the first connector 840, the pitch block 823 is connected to the slider 824, wherein each pitch block 823 is provided with two sliders 824.
[0062] In this disclosure, the sliders 824 of adjacent unloading modules 830 are slidably disposed on different guide rails 822. The slider 824 of the unloading module 830 refers to the slider 824 corresponding to that unloading module 830.
[0063] Specifically, the guide rail 822 includes a first guide rail, a second guide rail, a third guide rail, and a fourth guide rail; the first guide rail, the second guide rail, the third guide rail, and the fourth guide rail are arranged sequentially from top to bottom and are distributed at equal intervals.
[0064] In this disclosure, each unloading module 830 is provided with two sliders 824, that is, each unloading module 830 corresponds to two sliders. Among them, along the first direction, the unloading modules 830 located at odd-numbered positions (i.e., along the first direction) are... Figure 1 Two sliders 824 (from left to right) are slidably mounted on the first guide rail and the third guide rail, respectively; the unloading module 830 (i.e., along the even-numbered position) is located at an even-numbered position. Figure 1 The two sliders 824 (from left to right) are slidably mounted on the second and fourth guide rails, respectively.
[0065] Therefore, the sliders 824 of two adjacent feeding modules 830 will not interfere with each other, and the two feeding modules 830 can be brought close together. At this time, the multi-station feeding mechanism 800 can be used for closely arranged materials.
[0066] Figure 5 This is a schematic diagram of the structure of the unloading module of a multi-station unloading mechanism according to one embodiment of the present disclosure. Figure 6 and Figure 7 This is a structural schematic diagram of the unloading module of a multi-station unloading mechanism according to one embodiment of the present disclosure from another angle.
[0067] like Figures 5 to 7 As shown, in one embodiment, the first connector 840 corresponding to the even-numbered feeding module 830 is connected to the second connector 850, and the second connector 850 is guided by the guide rod 860.
[0068] Specifically, the second connector 850 of this disclosure has guide holes, through which the guide rod 860 passes, allowing the second connector 850 to slide along the guide rod 860. As a result, the unloading module 830 located at an even-numbered position of this disclosure has higher precision during movement.
[0069] The second connector 850 of this disclosure is formed in a generally L-shaped structure, that is, it includes a horizontal section and a vertical section that are vertically connected. The other end of the horizontal section is connected to the upper end of the first connector 840. The unloading module 830 is fixed to the vertical section and is located in the space enclosed by the first connector and the second connector.
[0070] In a preferred embodiment, the unloading module 830 is fixedly connected to the second connector 850, thereby enabling the unloading module 830 of this disclosure to maintain a firm fixed relationship with the pitch block 823.
[0071] See again Figures 5 to 7 The unloading module 830 of this disclosure includes an output shaft 831, which is capable of rotation and lifting relative to the first connecting member 840. In other words, the unloading module 830 of this disclosure can be formed as a ZR module (or referred to as a ZR axis), and the rotational and lifting degrees of freedom of the unloading module 830 can be independent degrees of freedom.
[0072] An installation plate 832 is fixed on the output shaft 831 of this disclosure. A suction cup 833 and a positioning post 834 are fixed on the lower surface of the installation plate 832. Thus, the multi-station unloading mechanism 800 of this disclosure can pick up materials through the suction cup 833 and limit the distance between the materials and the installation plate 832 through the positioning post 834 to achieve material positioning.
[0073] In one embodiment, the housing 821 of the pitch converter 820 of this disclosure is disposed on the connecting plate 870, and the connecting plate 870 is fixedly connected to the nut of the motion platform 810. Since the motion platform 810 can drive the pitch converter 820 to move along a preset horizontal direction (first direction).
[0074] Existing automated production lines offer high production speeds and large outputs. However, due to variations in product size and placement within the tray, structures such as variable-pitch feeding and orientation-changing mechanisms (i.e., feeding modules) are needed to address the issues of high product quantity, disorganized placement, and low efficiency.
[0075] When using the multi-station unloading mechanism disclosed herein, the pitch-changing structure can be locked. For example, if the loading distance of a material is 20mm, the pitch-changing mechanism can be controlled to make the distance between the unloading modules 830 20mm, and then the pitch-changing mechanism will not operate during the entire unloading process. Next, if the loading distance of the next material is 30mm, the pitch-changing mechanism can be controlled to operate again to make the distance between the unloading modules 830 30mm, and then the pitch-changing mechanism will not operate during the entire unloading process.
[0076] In another application scenario, the pitch-changing mechanism can remain in constant operation. For example, if a certain material has a spacing of 20mm on one pallet, and it needs to be transferred to another pallet or to the production line, the spacing of the material needs to be 30mm after the transfer is completed. During this transfer process, the pitch-changing device will operate continuously to ensure that the distance between the unloading modules 830 is 30mm.
[0077] In the description of this specification, the references to terms such as "one embodiment / mode," "some embodiments / modes," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment / mode or example is included in at least one embodiment / mode or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment / mode or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments / modes or examples. Furthermore, without contradiction, those skilled in the art can combine and integrate the different embodiments / modes or examples described in this specification, as well as the features of different embodiments / modes or examples.
[0078] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0079] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
