Description

Technical Field

[0001] The present invention relates to the technical field of 3D printing, and in particular to a detection mechanism and a detection method for neat line arrangement in a production process of 3D printing consumables. Background Art

[0002] After the filaments required for 3D printing are produced, they are rolled into bundles using a winder for easy storage. However, in some cases, the existing 3D printing filament winders do not arrange the wires neatly when winding the filaments, resulting in a loose roll. When used, the filaments are arranged in a messy manner and are inconvenient to unfold. Therefore, it is necessary to monitor and test the neatness of the wire arrangement of the winder during the production process of 3D printing filaments to ensure that the filaments wound by the winder are neat. Summary of the Invention

[0003] In order to address the deficiencies of the prior art, the present invention provides a 3D printing consumables production process neat wire arrangement detection mechanism and detection method thereof, which can detect whether the winding machine is neatly winding the consumables onto the winding reel.

[0004] The technical problem to be solved by the present invention is achieved through the following technical means: The technical solution of the present invention is that one aspect of the present invention is to provide a detection mechanism for neat wire arrangement in the production process of 3D printing consumables, which is used to be arranged on a winder provided in a 3D printing consumables production line. The winder includes a winding device for driving a winding reel and a wire arrangement device for guiding the consumables. The wire arrangement device includes a mobile frame and a wire lead-out block installed on the mobile frame. It is characterized in that the detection mechanism for neat wire arrangement in the production process of 3D printing consumables includes:

[0005] The rotating device includes a fixed frame and a motor fixedly mounted on the fixed frame; the motor is provided with a rotating shaft;

[0006] A swing arm, which is fixedly mounted on a rotating shaft provided by the motor;

[0007] A plurality of collection units are installed below the swing arm and facing the central axis of the winding drum, each of which is used to detect the distance between itself and the consumables wound on the winding drum;

[0008] A first infrared transceiver module, which is fixedly mounted on the fixing frame and is used to detect the position of the swing arm;

[0009] A second infrared transceiver module is fixedly mounted on the cable arrangement device and faces the movable frame, and is used to monitor the height of the movable frame;

[0010] a third infrared transceiver module, which is fixedly mounted on the winder and faces the winding reel;

[0011] The controller is electrically connected to the motor, the first infrared transceiver module, the second infrared transceiver module, the third infrared transceiver module and all the acquisition units; the controller is also electrically connected to a display and a plurality of buttons.

[0012] In the above scheme, the function of the winder is to wind the produced consumables on the winding drum, the winding device is used to drive the winding drum to rotate, and the wire arrangement device is used to use the mobile frame to move forward and backward and up and down, so that the wire lead-out block on the mobile frame can move forward and backward in the direction of the central axis of the winding drum, and the consumable line is inserted into the wire lead-out block and led out through the wire lead-out block. The wire lead-out block is used to control the lead-out position of the consumable by moving. In this way, the winding drum can rotate and the wire lead-out block can move forward and backward and up and down. Therefore, the consumables are led out through the wire lead-out block. The 3D printing consumables production process neatly arranges the wires on the winding drum, and the 3D printing consumables production process neatly arranges the wires on the winding drum. The rotating device can rotate the swing arm so that the swing arm can move to the direction directly above the winding drum and parallel to the central axis of the winding drum. A plurality of collection units are arranged on the swing arm. The collection unit is used to detect the distance between it and the consumables wound on the winding drum. Each collection unit monitors at least one circle of consumables. The combined detection of multiple collection units can detect whether each turn of the consumables is neat when it is wound on the winding reel. In addition, the swing arm needs to be located above the winding reel when the collection unit is performing the detection, but the winding reel needs to be disassembled and replaced with the next empty winding reel after winding is completed. Therefore, the swing arm needs to be driven by the motor to rotate to a position that does not interfere with the disassembly and assembly of the winding reel, and the first infrared transceiver module can be used to detect the position of the swing arm, specifically whether the swing arm is directly above the winding reel or at the side of the winding reel that does not interfere with the disassembly and assembly of the winding reel; on the other hand, the present invention is equipped with a second infrared transceiver module that can be used to detect the specific height position of the movable frame, that is, the wire lead-out block. For each layer of winding of the winding reel, the wire lead-out block needs to rise by one layer in height to ensure the neatness of the winding; on the other hand, the present invention is equipped with a third infrared transceiver module for detecting whether the winding reel is rotating, that is, detecting whether the winding device is in normal working condition when winding and rewinding are required; on the other hand, the present invention is equipped with a controller, which can be used for the overall control of the mechanical movement of the entire component of the neat wire arrangement detection mechanism in the production process of 3D printing consumables.

[0013] In one embodiment, all acquisition units are installed on the swing arm through a position adjustment device; the position adjustment device includes a guide rail fixedly installed under the swing arm and a slider installed on the guide rail; a fixing component for fixing all acquisition units is provided under the slider, and the fixing component is provided with a plurality of mounting holes for cooperating with the installation of the acquisition units; the acquisition unit is a fourth infrared transceiver module.

[0014] In the above scheme, the collection unit is installed on a slider, and the slider can be moved on the guide rail to achieve the overall position adjustment of the collection unit. In this way, the collection unit can be adjusted according to different winding reels or different consumables diameters to adapt to the neat wiring detection of consumables.

[0015] In one embodiment, a plurality of acquisition units are arranged on the slider in a curved array.

[0016] In the above solution, multiple collection units are arranged in a curve and can be arranged more compactly on the slider, so that each circle of consumables wound on the winding drum can be detected by a corresponding collection unit.

[0017] In one embodiment, the controller drives the motor to operate via a driving module.

[0018] In one embodiment, a through hole is provided on the side wall of the slider, and the through hole extends from the outside of the slider to the outer side wall of the guide rail; a locking screw is installed on the through hole, and the locking screw is used to lock the slider on the guide rail.

[0019] In the above solution, the locking screw is used to lock the slider.

[0020] Another aspect of the present invention is to provide a detection method for the 3D printing consumables production process neat line detection mechanism, the detection method comprising the following steps:

[0021] S1. The controller detects through the first infrared transceiver module whether the swing arm is above the winding drum and the swing arm is parallel to the central axis of the winding drum. If not, the controller drives the motor to rotate above the winding drum and make the swing arm parallel to the central axis of the winding drum. If yes, it proceeds to the next step;

[0022] S2. The controller detects the height position of the movable rack through the second infrared transceiver module. The controller determines the reference distance between each collection unit and the top layer of consumables on the winding reel according to the height position of the movable rack, and then proceeds to the next step.

[0023] S3. The controller detects whether the winding reel is rotating through the third infrared transceiver module. If the winding reel is not rotating, the controller continues to wait until the rotation starts. If the winding reel is in the rotating state, the controller collects the actual distance between the consumables on the winding reel and the collection unit through all collection units. The controller determines the deviation distance based on the actual distance and the reference distance. If the deviation distance is greater than a preset range, the controller determines whether the distance between the collection unit and the consumables is in a misaligned state.

[0024] S4. The controller collects statistics based on the data of all misalignment states. If the statistical data is greater than a preset qualified value range, the roll of consumables is judged to be unqualified for neat wiring. If the statistical data is less than or equal to the preset qualified value range, the roll of consumables is judged to be qualified for neat wiring.

[0025] In one embodiment, step S4 is followed by step S5. When the controller detects that the height position of the movable rack has changed through the second infrared transceiver module, the controller obtains the latest reference distance based on the latest height position change, and then detects the actual distance through all acquisition units. The controller re-judges the deviation distance based on the actual distance and the latest reference distance. If the deviation distance is greater than the preset range, it is determined whether the distance between the acquisition unit and the consumable is in a misaligned state; the controller records the number of all misaligned states; when the controller detects that the winding drum is not rotating through the third infrared transceiver module, the controller no longer collects the distance through all acquisition units; then enters the next step S6, the controller drives the motor to rotate, so that the swing arm rotates 90 degrees, and the swing arm is not directly above the winding drum.

[0026] In one embodiment, the controller displays the misalignment status digitally via a display. BRIEF DESCRIPTION OF THE DRAWINGS

The wire arrangement device 4 includes a mobile frame and a wire lead-out block 6 installed on the mobile frame 5. The present invention is characterized in that the detection mechanism for neatly arranging wires in the production process of 3D printing consumables includes:

[0032] The rotating device 7 includes a fixing frame 8 and a motor 9 fixedly mounted on the fixing frame 8; the motor 9 is provided with a rotating shaft 10;

[0033] A swing arm 11 is fixedly mounted on a rotating shaft 10 provided on the motor;

The wire lead-out block 6 is used to control the lead-out position of the consumable by moving. In this way, the winding drum 2 can rotate and the wire lead-out block 6 can move forward and backward and up and down.

Each collection unit 12 monitors at least one circle of consumables, so that The combined detection of multiple collection units 12 can detect whether each turn of the consumables is neat when it is wound on the winding reel 2. In addition, the swing arm 11 needs to be located above the winding reel 2 when the collection unit 12 is detecting. However, after the winding reel 2 is wound, it needs to be disassembled and replaced with the next empty winding reel 2. Therefore, the swing arm 11 needs to be driven by the motor 9 to rotate to a position where it does not interfere with the disassembly and assembly of the winding reel 2, and the first infrared transceiver module 13 can be used to detect the position of the swing arm 11, specifically whether the swing arm 11 is located directly above the winding reel 2 or at the side of the winding reel 2 where it does not interfere with the disassembly and assembly of the winding reel 2.

The fixing member 22 is L-shaped, with a hollow portion at the top. The upper portion of the collection unit 12 is inserted into the hollow portion of the fixing member 22 through the mounting hole.
