Description

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on June 4, 2024, with application number 2024107145946 and application name “A device and method for detecting the position of a bundled workpiece and its intelligent trash can”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the technical field of intelligent trash can packaging position detection, and more specifically, to a device and method for detecting the position of a bundled workpiece and an intelligent trash can thereof. Background Art

[0003] A smart trash can is a trash can that can automatically pack and change bags. It has an independent control module inside. By integrating some software programs into the control module, intelligent control of the opening and closing of the lid, packing and changing bags can be achieved, thereby realizing the intelligence of the smart trash can.

[0004] Reference Figure 1 A tool structure for cinching garbage bags inside a smart trash can is currently available. This tool is used to cinch the openings of garbage bags together, facilitating packing and bag changing. The tool structure includes a base plate 01, a cable tie 02, a heating wire base 03, and a power assembly 04. Base plate 01 is provided with an opening 05 for the garbage bag to pass through. Cable tie 02 is positioned around the periphery of opening 05, with one end of cable tie 02 fixed to heating wire base 03 and the other end being a movable end connected to power assembly 04. Driven by power assembly 04, the movable end of cable tie 02 can be moved to reciprocally reduce or increase the opening size of cable tie 02, thereby constricting or resetting the garbage bag.

[0005] In order to realize intelligent control of the bundled workpiece (cable tie), it is necessary to detect the position of the bundled workpiece during the packaging process or the position of the starting and ending points of the packaging. The position detection in the existing technology usually uses multiple position switches to detect at the positions to be detected, such as multiple non-contact photoelectric door position switches. However, when used for detection in the bundled workpiece structure, since the cable tie is a continuous structure, if multiple photoelectric door position switches are installed on the inner wall of the bottom plate, the cable tie may trigger multiple position switches at the same time during the contraction process, resulting in the cable tie position detection being impossible to achieve or the implementation scheme being more complicated. Therefore, how to conveniently detect the position of the bundled workpiece is a technical problem that needs to be solved by this patent. Summary of the Invention

[0006] In response to the technical problem raised in the background technology of how to conveniently detect the position of the bundled workpiece in the existing technology, the present invention provides a single potential sensing device for comprehensively detecting the packaging process position of the bundled workpiece or the packaging starting and ending positions.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A device for detecting the position of a grommet workpiece comprises a mounting plate, a grommet workpiece and a drive assembly, wherein the grommet workpiece and the drive assembly are driven and connected, and further comprises a position detection assembly, wherein the position detection assembly comprises a position detection probe and a potential sensing device, wherein the potential sensing device has a trigger rod, and the end of the position detection probe is telescopically mounted on the mounting plate, the position detection probe is connected to the trigger rod, and the position detection probe controls the synchronous movement of the trigger rod when the position detection probe is telescopically moved; one end of the position detection probe is tightly mounted on the grommet workpiece; and one or more recesses of different depths are provided on one surface of the grommet workpiece for tightly contacting the position detection probe.

[0009] Through the above technical solution: the present invention only needs to set up a potential sensing device to comprehensively detect the position of the bundled workpiece during the packaging process or the position of the starting and ending points of the packaging. The specific working process is: using the driving component to drive the bundled workpiece to move, that is, the bundled workpiece performs a closing operation or reset, when the notch on the bundled workpiece is located above the end of the position detection probe, the position detection probe begins to extend upward, and when the position detection probe extends, it drives the trigger rod to move, and the trigger rod movement controls the resistance value of the potential sensing device to change, thereby identifying the position. For different detection positions, by setting notches of different depths, notches of different depths give different amplitudes to the trigger rod movement, so that when the bundled workpiece passes the end of the position detection probe, the trigger rod movement controls the resistance value of the potential sensing device to change by different values, thereby identifying multiple detection positions.

[0010] The present invention further provides that: the mounting plate is provided with a packing opening, and an arc-shaped baffle is provided on the outer periphery of the packing opening.

[0011] Through the above technical solution, the packing opening is used for passing garbage bags in the smart trash can and putting garbage into it, and the arc-shaped baffle is used to limit the maximum expansion position of the packing opening workpiece after it is reset.

[0012] The present invention further: wherein the position detection component also includes a shell and a spring, the shell is fixed to the mounting plate, the position detection probe is installed through the inside of the spring, the bottom end support of the spring is installed on the shell, and the top end support of the spring is installed on the position detection probe.

[0013] Through the above technical solution, the newly added shell is used as an installation carrier for the workpiece inside the position detection component, and retractable installation is achieved by installing a spring. Of course, retractable installation can be achieved not only by using springs, but also by using soft or elastic workpieces such as cushions.

[0014] The present invention further comprises: wherein the bottom end of the spring abuts against the inner wall of the shell, the top end of the spring is fixed to the position detection probe, and the bottom end of the position detection probe moves through the bottom surface of the shell.

[0015] The above technical solution is used as one of the correct ways to install the spring.

[0016] The present invention further provides that: a connecting plate is provided in the middle of the position detection probe, a waist-shaped hole is provided on the connecting plate, and the trigger rod is passed through the waist-shaped hole.

[0017] Through the above technical solution, by providing the waist-shaped hole, the movement of the trigger rod position can be facilitated.

[0018] The present invention further includes a packaging component, which includes a mounting seat and a sealing and cutting workpiece. The mounting seat is arranged on the upper surface of the mounting plate, and the sealing and cutting workpiece is arranged on the outer surface of the mounting seat. One end of the bundle workpiece is fixed to the mounting seat, and the other end of the bundle workpiece is driven and connected to the driving component.

[0019] The present invention further provides that: the sealing and cutting workpiece is a heating wire, a heating sheet or a heat conducting sheet.

[0020] The present invention further provides that: the potential sensing device is configured as a rotary adjustable potentiometer.

[0021] The present invention further provides that: the mounting plate is provided with a position detection port, one end portion of the position detection probe is located at the position detection port and is mounted closely to the beam workpiece.

[0022] Through the above technical solution, by opening a position detection port, the telescopic installation of the position detection probe on the mounting plate is facilitated, that is, the position detection probe can be installed through the position detection port to sense the recess in the beam workpiece above the position detection port.

[0023] Based on the above position detection device, a method for detecting the position of a beam workpiece is provided, wherein a driving component drives the beam workpiece to move;

[0024] When the notch on the workpiece passes the end of the position detection probe, the position detection probe begins to extend and retract, which drives the trigger rod to move. The action of the trigger rod controls the resistance value of the potential sensing device to change.

[0025] When notches of different depths pass through the end of the position detection probe, the trigger rod actuates to control the resistance value of the potential sensing device to change by different values;

[0026] The positions of different beam opening workpieces can be detected by changing the resistance value of the potential sensing device.

[0027] A smart trash can is provided, using any one of the aforementioned devices for detecting the position of a bundled workpiece.

[0028] In summary, the present invention has the following beneficial effects:

[0029] The present invention provides notches of different depths on the bundled workpiece. During the packaging process of the bundled workpiece, when the notches of different depths touch the position detection probe, the extension length of the position detection probe is different, thereby driving the movement amplitude of the trigger rod to be different, and ultimately driving the potential change value of the potential sensing device to be different, so as to accurately obtain the packaging position of the bundled workpiece.

DETAILED DESCRIPTION

[0038] The present invention will be further described in detail below with reference to the embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0039] A device for detecting the position of a beam workpiece, combined with Figure 2-Figure 7 As shown, the device comprises a mounting plate 1, a slinging workpiece 2, a drive assembly 3, and a packaging assembly. The mounting plate 1 is circular with upwardly protruding sides, though other shapes are possible. The mounting plate 1 defines a packaging opening 1-2, which is surrounded by an arc-shaped baffle 1-3. The slinging workpiece 2 is mounted inside the arc-shaped baffle 1-3. One end of the slinging workpiece 2 is fixed to the packaging assembly, while the other end is free and connected to the drive assembly 3. Driven by the drive assembly 3, the slinging workpiece 2 can be retracted above the packaging opening 1-2 to perform the packaging operation.

[0040] In this embodiment, the driving component 3 is configured as a driving structure of a motor, a reduction gear and a gear. In other embodiments, it can also be driven by an extrusion transmission method, etc. In this embodiment, when the bundle workpiece 2 is connected to the gear for transmission, it is necessary to set the side of the bundle workpiece 2 used to connect the gear of the driving component 3 to a rack surface (not shown in the figure), and the rack surface is used to engage with the gear of the driving component 3 for transmission. The packaging component is a hot melt sealing and cutting device, which is used to seal and cut the garbage bags that have been bundled. Specifically, the packaging component has a mounting seat 8 and a sealing and cutting workpiece 9. The mounting seat 8 is fixed to the upper surface of the mounting plate 1, and the sealing and cutting workpiece 9 is fixed to the front end surface of the mounting seat 8. The sealing and cutting workpiece 9 is a heating wire or a heating plate or a heat conducting plate. When the bundle workpiece 2 is bundled, the garbage bag can be pressed against the surface of the sealing and cutting workpiece 9 on the front end surface of the mounting seat 8 for hot melt sealing and cutting. When the bundle workpiece 2 is installed, one end of the bundle workpiece 2 is fixed to the mounting seat 8, and the other end of the bundle workpiece 2 is connected to the driving component 3. Of course, in another embodiment, both ends of the bundled workpiece 2 can be driven and converged by a driving member, or a larger number of bundled workpieces 2 can be provided for driven and converged, etc.

[0041] In order to detect the packaging position of the bundled workpiece 2, for example, to detect the starting position, middle position and end position of the bundled workpiece 2 in the packaging process, the present invention provides a position detection component for position detection. The position detection component includes a position detection probe 4 and a potential sensing device 5. The bundled workpiece 2 is provided with one or more recesses of different depths on one side thereof for being close to the position detection probe 4. The number of recesses is determined according to the number of positions to be detected. Position detection is achieved by changing the potential value of the potential sensing device 5 by changing the position of the position detection probe 4 in the recess. In this embodiment, taking the detection of the starting position, middle position and end position of the bundled workpiece 2 in the packaging process as an example, the bundled workpiece 2 is provided with a first recess 2-1, a second recess 2-2 and a third recess 2-3 on one side thereof for being close to the position detection probe 4, which are respectively used to detect the starting position, end position and middle position of the bundled workpiece 2 in the packaging process.

[0042] To achieve position detection, the potential sensing device 5 of the present invention has a trigger rod 5-1, and the mounting plate 1 is provided with a position detection port 1-1. The top end of the position detection probe 4 is located in the position detection port 1-1 and is installed closely to the beam workpiece 2. To achieve the telescopic installation of the end of the position detection probe 4 on the mounting plate 1, the present invention further adds a shell 6 and a spring 7 to the position detection assembly to enable telescopic installation of the position detection probe 4. The shell 6 is fixed to the mounting plate 1, and the position detection probe 4 is installed inside the spring 7. The bottom end of the spring 7 supports and installs the housing 6 (such as the bottom end of the spring 7 abuts the inner wall of the housing 6). The top end of the spring 7 supports and installs the position detection probe 4 (such as the top end of the spring 7 is fixed to the position detection probe 4). The bottom end of the position detection probe 4 moves through the bottom surface of the housing 6. The position detection probe 4 is connected to the trigger rod 5-1, and when the position detection probe 4 telescopes, it controls the trigger rod 5-1 to move synchronously.

[0043] To achieve flexible movement of the trigger rod 5-1, a connecting plate 4-1 is provided in the middle of the position detection probe 4. The connecting plate 4-1 is provided with a waist-shaped hole 4-2, and the trigger rod 5-1 is inserted into the waist-shaped hole 4-2. In addition, the potential sensing device 5 of the present invention is configured as a rotary adjustable potentiometer.

[0045] ① The driving component 3 drives the beam workpiece 2 to move;

[0046] ② When the notch on the workpiece 2 passes the end of the position detection probe 4, the position detection probe 4 begins to extend and retract, which drives the trigger rod 5-1 to move. The action of the trigger rod 5-1 controls the resistance value of the potential sensing device 5 to change.

[0047] ③ When notches of different depths pass through the end of the position detection probe 4, the trigger rod 5-1 is actuated to control the resistance value of the potential sensing device 5 to change by different values;
