[0080] 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.
[0081] 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.
[0082] 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.
[0083] 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.
[0084] 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.
[0085] 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.
[0086] 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.
[0087] Figure 1 This is a schematic diagram of a feeding device for multi-size materials according to one embodiment of the present disclosure.
[0088] like Figure 1 As shown, the multi-size material feeding device disclosed herein may include: a first hopper 100, a second hopper 200, and a conveying device 300, etc.
[0089] The conveying device 300 is used to identify the size of the material, and the conveying device 300 has a first position, a second position, and an intermediate position between the first position and the second position; a first hopper 100 is disposed at the first position to receive material with a first size conveyed by the conveying device 300; and a second hopper 200 is disposed at the second position to receive material with a second size conveyed by the conveying device 300.
[0090] Specifically, in use, the multi-size material unloading device of this disclosure allows the conveying device 300 to be positioned in the middle. At this time, a robotic arm or other equipment can transport materials (e.g., a tray) from the area between the conveying device 300 and the first hopper 100 and the second hopper 200 to the area below the mounting plate 340 of the conveying device 300, where they are attracted by the suction cup 350. The conveying device can then determine the size of the material. When the material is of the first size (e.g., 400mm*400mm), it can be conveyed to the first position and placed in the first hopper 100; when the material is of the second size (e.g., 300mm*300mm), it can be conveyed to the second position and placed in the second hopper 200. Thus, the multi-size material unloading device of this disclosure can unload materials of two different sizes.
[0091] Figure 2 This is a schematic diagram of the structure of a conveying device for a multi-size material feeding device according to one embodiment of the present disclosure.
[0092] like Figure 2 As shown, the conveying device 300 disclosed herein includes components such as a horizontal motion mechanism 310, a vertical motion mechanism 320, a support frame 330, a mounting plate 340, a suction cup 350, and a laser sensor 360.
[0093] The horizontal motion mechanism 310 of this disclosure is a linear motion mechanism. In one specific embodiment, the horizontal motion mechanism 310 can be a motor-driven ball screw structure. Since the motor-driven ball screw mechanism is a common structure in the art, it will not be described in detail here.
[0094] The vertical motion mechanism 320 is disposed on the horizontal motion mechanism 310 so that the horizontal motion mechanism 310 can drive the vertical motion mechanism 320 to move between a first position and a second position. Specifically, the vertical motion mechanism 320 is also a linear motion mechanism. For example, the vertical motion mechanism 320 can be a cylinder, such as a double-rod cylinder or a slide cylinder.
[0095] The support frame 330 is mounted on the vertical motion mechanism 320 so that the vertical motion mechanism 320 drives the support frame 330 to generate lifting motion; the mounting plate 340 is disposed on the support frame 330, wherein the mounting plate 340 is disposed approximately horizontally, and the mounting plate 340 is provided with a suction cup 350, thereby enabling the suction cup to pick up materials by providing negative pressure to the suction cup 350.
[0096] When the above-described conveying device is in operation, it can provide two degrees of freedom of movement, horizontal and vertical, to the material picked up by the suction cup 350, thereby facilitating the delivery of the material to the area below the suction cup 350 of the conveying device 300, and enabling the suction cup to pick up the material.
[0097] In a preferred embodiment, the mounting plate 340 has a plurality of elongated holes arranged in multiple rows, with adjacent rows of elongated holes staggered. This allows for the suction of materials of different sizes to be picked up by installing the suction cup 350 in different elongated holes or at different positions in one elongated hole.
[0098] The laser sensor 360 disclosed herein is used to detect the size of the material picked up by the suction cup 350. Specifically, the pressure in the vacuum line connected to the suction cup 350 can be used to determine whether the suction cup 350 has picked up material. After the suction cup 350 picks up material, the size of the material can be determined based on the signal from the laser sensor 360.
[0099] For example, when the laser emitted by the laser sensor 360 has an echo signal, it indicates that the size of the material is large, and the size of the material is set as the first size; when the signal emitted by the laser sensor 360 has no echo signal, the size of the material on the surface is small, and the size of the material is set as the second size.
[0100] In this disclosure, the first hopper 100 and the second hopper 200 have the same structure. The structure of the first hopper and the second hopper of this disclosure will be described in detail below with reference to the accompanying drawings.
[0101] Figure 3 This is a schematic diagram of the structure of a first hopper according to one embodiment of the present disclosure. Figures 4 to 8 This is a structural schematic diagram of the first hopper at different angles according to one embodiment of the present disclosure.
[0102] like Figures 3 to 8 As shown, the first hopper 100 of this disclosure may include structures such as a base plate 110, a first support plate 120, a second support plate 130, a first conveying assembly 140, a second conveying assembly 150, and a first drive assembly 160.
[0103] The base plate 110 disclosed herein is generally square in shape and includes a first direction and a second direction. The first direction may be the length direction of the base plate 110, and the second direction may be the width direction of the base plate 110.
[0104] The first support plate 120 and the second support plate 130 are both slidably mounted on the base plate 110. Specifically, the base plate 110 is provided with two guide rails, which are arranged in parallel and both are arranged along a first direction.
[0105] One end of the first support plate 120 is slidably mounted on one of the two guide rails via a slider, and the other end is slidably mounted on the other guide rail via a slider. Similarly, one end of the second support plate 130 is slidably mounted on one of the two guide rails via a slider, and the other end is slidably mounted on the other guide rail via a slider. Thus, both the first support plate 120 and the second support plate 130 can slide on the guide rails, allowing them to approach or move away from each other in a first direction.
[0106] With the above structure, the length direction of the first support plate 120 and the second support plate 130 of this disclosure is parallel to the second direction.
[0107] In this disclosure, when the first support plate 120 and the second support plate 130 approach or move away from each other, one of the first support plate 120 and the second support plate 130 can remain stationary. In a preferred embodiment, the first support plate 120 and the second support plate 130 can move in opposite directions simultaneously, so that the first support plate 120 and the second support plate 130 can approach or move away from each other.
[0108] The first conveying assembly 140 is disposed on the first support plate 120 and located inside the first support plate 120; similarly, the second conveying assembly 150 is disposed on the second support plate 130 and located inside the second support plate 130. That is, the first conveying assembly 140 and the second conveying assembly 150 of this disclosure are located in the area between the first support plate 120 and the second support plate 130, thereby enabling the conveying of trays via the first conveying assembly 140 and the second conveying assembly 150. In other words, at this time, a stack of trays (i.e., at least one stacked tray) can be placed on the first conveying assembly 140 and the second conveying assembly 150 and conveyed by the first conveying assembly 140 and the second conveying assembly 150.
[0109] The first drive assembly 160 is used to drive the first support plate 120 and / or the second support plate 130 to move, so that the first support plate 120 and the second support plate 130 can approach or move away from each other. Thus, the first hopper of this disclosure can be adapted to trays of different sizes. That is, the width between the first support plate 120 and the second support plate 130 of this disclosure can change with the size of the tray, so that the first hopper 100 of this disclosure can transport trays of different sizes, thereby achieving compatibility with trays of different sizes.
[0110] Specifically, the first drive assembly 160 of this disclosure can simultaneously drive the first support plate 120 and the second support plate 130, and cause the first support plate 120 and the second support plate 130 to have opposite directions of movement.
[0111] Specifically, the first drive assembly 160 of this disclosure may include a first drive motor and a bidirectional helical screw 161 driven to rotate by the first drive motor. The bidirectional helical screw 161 may be a trapezoidal screw with both positive and negative teeth. Specifically, the first drive motor is fixed to the base plate 110; both ends of the bidirectional helical screw 161 are rotatably disposed on the base plate 110 through bearing seats, and the axis of the bidirectional helical screw 161 is disposed along a first direction. At this time, the bearing seats can limit the axial position of the bidirectional helical screw 161.
[0112] A first nut is provided on the first support plate 120, and a second nut is provided on the second support plate 130. The first nut and the second nut have different helical directions, and both the first nut and the second nut cooperate with the bidirectional helical screw. Thus, when the bidirectional helical screw 161 rotates in one direction, the first support plate 120 and the second support plate 130 can approach each other, and when the bidirectional helical screw 161 rotates in another direction, the first support plate 120 and the second support plate 130 can move away from each other.
[0113] Both the first conveying assembly 140 and the second conveying assembly 150 are synchronous belt conveying assemblies, thereby enabling the conveying of a material tray disposed on a synchronous belt through the movement of the synchronous belt of the synchronous belt conveying assembly. In this disclosure, the first conveying assembly 140 includes a first driving pulley 141 and at least one first driven pulley, which are connected by a first synchronous belt drive. Similarly, the second conveying assembly 150 includes a second driving pulley 151 and at least one second driven pulley, which are connected by a second synchronous belt drive. Since synchronous belt conveying assemblies are common structures in the art, their structure will not be described in detail in this disclosure.
[0114] The first hopper 100 of this disclosure also includes a second drive assembly 170, which is used to drive the first conveying assembly 140 and the second conveying assembly 150 to move; that is, the second drive assembly 170 of this disclosure is set to one, and the first conveying assembly 140 and the second conveying assembly 150 are synchronously driven through one second drive assembly 170.
[0115] The second drive assembly 170 includes a second drive motor and a drive shaft 171 driven by the second drive motor. The cross-section of the drive shaft 171 is non-circular, for example, hexagonal. The first drive wheel 141 and the second drive wheel 151 are both slidably disposed on the drive shaft 171 and driven by the drive shaft 171 to rotate.
[0116] Specifically, the two ends of the drive shaft 171 of this disclosure are rotatably supported on the base plate 110 by bearing seats, and the axial position of the drive shaft 171 can be restricted by the bearing seats. That is to say, the axis of the drive shaft 171 is set along the first direction and will not move along the first direction.
[0117] The first drive wheel 141 is rotatably supported on the first support plate 120 via a bearing, and the drive shaft 171 is slidable within the inner bore of the bearing, so that the drive shaft 171 does not affect the movement of the first support plate 120 in the first direction. Similarly, the second drive wheel 151 is rotatably supported on the second support plate 130 via a bearing, and the drive shaft 171 is slidable within the inner bore of the bearing, so that the drive shaft 171 does not affect the movement of the second support plate 130 in the first direction.
[0118] The first hopper 100 disclosed herein also includes a lifting assembly 180, which is used to raise the tray between the first support plate 120 and the second support plate 130 to a preset position, wherein the tray is in a loading position at the preset position.
[0119] The lifting assembly 180 disclosed herein may include a lifting drive device 181 and a tray support 182 driven by the lifting drive device 181 to generate lifting; specifically, the lifting drive device 181 disclosed herein may be fixed on a vertical plate 183, at which time the vertical plate 183 is set approximately vertically, and its lower end can be fixed to the base plate 110.
[0120] The lifting drive device 181 can be a ball screw structure; alternatively, it can be a linear motion mechanism such as a cylinder or hydraulic cylinder. Two guide rails are provided on the upright plate 183, both vertically positioned, allowing the lifting drive device 181 to be located in the area between the two guide rails.
[0121] The tray support 182 is slidably disposed on the upright plate 183. For example, the tray support 182 is provided with a slider, which is slidably disposed on the guide rail provided on the upright plate 183, so that the tray support 182 can move relative to the upright plate 183. That is, the tray support 182 is driven and can generate vertical movement.
[0122] In one embodiment, the tray support 182 is also fixed to the nut of the ball screw mechanism, so that the lifting drive device 181 can drive the tray support 182 to produce lifting motion.
[0123] Figure 9 and Figure 10 This is a structural schematic diagram of the base of the first door panel and the opening / closing part of the first hopper according to one embodiment of the present disclosure.
[0124] A first front upright plate 121 and a first rear upright plate 122 are provided on the first support plate 120, and the first front upright plate 121 and the first rear upright plate 122 are respectively provided at both ends of the length direction of the first support plate 120; a plurality of first guide rods 123 are provided between the first front upright plate 121 and the first rear upright plate 122; a first door panel base 124 is slidably provided on the first guide rod 123, and a first door panel switch part 125 is rotatably provided on the first door panel base 124. The first door panel switch part 125 is driven by the first door panel switch part driving device 127 and is in the state of opening the first hopper 100 or closing the first hopper 100.
[0125] Specifically, when the first door panel switch 125 is in the open state of the first hopper 100, the first door panel base 124 and the first door panel switch 125 are in approximately the same vertical plane; when the first door panel switch 125 is in the closed state of the first hopper 100, the first door panel base 124 and the first door panel switch 125 are perpendicular to each other, and the first door panel switch 125 is used to block the tray inside the first hopper 100.
[0126] In this disclosure, the first door panel base 124 can be driven by the first door panel base driving device 126 so that the first door panel base 124 can slide along the first guide rod 123, thereby the hopper of this disclosure can adapt to hoppers of different lengths.
[0127] In one specific embodiment, the first door panel base driving device 126 can be a ball screw structure; of course, it can also adopt other linear motion mechanisms. The ball screw mechanism can be implemented using existing technologies, which will not be elaborated upon here.
[0128] Furthermore, the first door panel switch 125 of this disclosure can be driven by the first door panel switch drive device 127, so that the first door panel switch 125 can rotate relative to the first door panel base 124 by a preset angle. Specifically, the first door panel base 124 can rotate 90° relative to the first door panel switch 125, thereby enabling the first door panel switch 125 to be in an open first hopper state or a closed first hopper state.
[0129] In one specific embodiment, the first door panel switch driving device 127 can be a cylinder, one end of which is hinged to the first door panel base 124, and the second end of which is hinged to the first seat component 128. The first seat component 128 is fixed to the first door panel switch 125, so that the rotation of the first door panel switch relative to the first door panel base 124 can be driven by the extension and retraction of the cylinder.
[0130] Figure 11 and Figure 12This is a structural schematic diagram of the base of the second door panel and the opening / closing part of the second door panel of the first hopper according to one embodiment of the present disclosure.
[0131] The second support plate 130 is provided with a second front upright plate 131 and a second rear upright plate 132, which are respectively located at both ends of the length direction of the second support plate 130. A plurality of second guide rods 133 are provided between the second front upright plate 131 and the second rear upright plate 132. A second door panel base 134 is slidably provided on the second guide rod 133. A second door panel switch part 135 is rotatably provided on the second door panel base 134. The second door panel switch part 135 is driven by the second door panel switch part driving device 137 and is in the state of opening the first hopper 100 or closing the first hopper 100.
[0132] Specifically, when the second door panel switch 135 is in the open state of the first hopper 100, the second door panel base 134 and the second door panel switch 135 are in approximately the same vertical plane; when the second door panel switch 135 is in the closed state of the first hopper 100, the second door panel base 134 and the second door panel switch 135 are perpendicular to each other, and the second door panel switch 135 is used to block the tray inside the first hopper 100.
[0133] In this disclosure, the second door panel base 134 can be driven by the second door panel base driving device 136 so that the second door panel base 134 can slide along the second guide rod 133, thereby the hopper of this disclosure can adapt to hoppers of different lengths.
[0134] In one specific embodiment, the second door panel base drive device 136 can be a ball screw structure; of course, it can also adopt other linear motion mechanisms. The ball screw mechanism can be implemented using existing technologies, which will not be elaborated upon here.
[0135] Furthermore, the second door panel switch 135 disclosed herein can be driven by the second door panel switch drive device 137, so that the second door panel switch 135 can rotate relative to the second door panel base 134 by a preset angle. Specifically, the second door panel base 134 can rotate 90° relative to the second door panel switch 135, thereby enabling the second door panel switch 135 to be in an open first hopper state or a closed first hopper state.
[0136] In one specific embodiment, the second door panel switch driving device 137 can be a cylinder, one end of which is hinged to the second door panel base 134, and the second end of which is hinged to the second seat component 138. The second seat component 138 is fixed to the second door panel switch 135, so that the rotation of the second door panel switch relative to the second door panel base 134 can be driven by the extension and retraction of the cylinder.
[0137] See again Figures 9 to 12 A second blocking part 139 is provided on the second rear upright plate. The second blocking part 139 is located above the end of the second conveying assembly 150 near the lifting assembly 180, so that the material tray of this disclosure can be accurately limited in the hopper.
[0138] In one embodiment of this disclosure, the first hopper 100 further includes a tray detection device for detecting the presence signal of the tray. That is, the tray detection device can detect the presence or absence of the tray. In a preferred embodiment, the tray detection device can be a through-beam switch, a photoelectric sensor, or a diffuse reflection sensor, and multiple devices can be configured to detect the tray from multiple locations.
[0139] Based on the above structure, the space inside the first hopper of this disclosure can be changed according to the size of the material tray, so that the material tray can be accurately positioned and stably maintained in the first hopper. Its structure is stable, highly accurate, fast, and easy to assemble.
[0140] Although one example of this disclosure shows a configuration with two hoppers, those skilled in the art will understand that the number of hoppers can be set to multiple. Therefore, the multi-size material unloading device of this disclosure can accommodate materials of various sizes, and in this case, the horizontal movement mechanism of the conveying device will have a longer stroke.
[0141] In addition, when using the multi-size material feeding device disclosed herein, other methods can also be used to determine the size of the material, such as using a camera or other devices to determine the size of the material. These methods of determining the size of the material can be implemented using existing technologies, and will not be described in detail here.
