Description

Technical Field

[0001] The present invention relates to the technical field of plate flatness detection, in particular to a surface flatness detection device for furniture plate processing. Background Art

[0002] Flatness is one of the important technical indicators for evaluating the quality of sheet materials. After the production of each batch of furniture sheets is completed, it is necessary to randomly test and determine the surface flatness of the sheet materials to determine whether the sheets are qualified or not. Existing sheet flatness monitoring equipment, such as the flatness measuring device for metal sheet production disclosed in the authorization announcement number CN212963251U, includes a workbench. This application combines scientific and technological products to accurately detect the flatness of the metal sheet surface, improve the detection accuracy of the metal sheet, and simplify the detection operation, so that the quality of the metal sheet leaving the factory is better, meeting the needs of commercialization.

[0003] When spot-checking boards, the boards are generally placed flat on a testing table, and then the flatness of the boards is checked by the cooperation of an infrared emitter and a detection probe. Similar to the above-mentioned prior art, most existing furniture boards are made of wood. After cutting and polishing, there may be some sawdust on the surface of the boards. Moreover, some of the sawdust may adhere to the surface of the boards due to the stacking and squeezing of the boards, forming bulges, which may affect the results of the flatness test. Before the test, it is necessary to clean the boards to be sampled separately, which is troublesome.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0033] See also Figures 1-12, a surface flatness detection device for furniture board processing, including a detection table 1, a mounting frame 2 is slidably provided on the detection table 1, and a plurality of detection probes 4 are fixedly installed on the mounting frame 2 (the detection probes 4 are used in conjunction with external infrared transmitters and other equipment. This detection method is a prior art and will not be described in detail here). A power mechanism for controlling the movement of the mounting frame 2 is installed at the lower end of the detection table 1. The power mechanism includes a motor 9 fixedly installed on the detection table 1, a threaded rod 7 is fixedly installed at the output end of the motor 9, and the mounting frame 2 is threadedly connected to the threaded rod 7. Slides 3 are provided on both sides of the detection table 1, and a slider 28 fixedly connected to the mounting frame 2 is slidably connected in one of the slides 3. A rotating rod 26 is rotatably mounted on the block 28, and the rotating rod 26 is in sliding contact with another slide 3. A cleaning assembly is fixedly sleeved on the outer side of the rotating rod 26, and the cleaning assembly includes a cross mounting frame 17 fixedly sleeved on the outer side of the rotating rod 26. An opening 19 is provided on one side of the cross mounting frame 17, and a mounting plate 22 is slidably connected in the opening 19. A connecting spring 31 is fixedly arranged between the mounting plate 22 and the opening 19, and a brush 15 is mounted on the outer side of the mounting plate 22. The outer side of the mounting plate 22 is arc-shaped and made of soft rubber. During detection, the starting motor 9 can control the movement of the mounting frame 2, so that the mounting plate 22 drives the brush 15 to move, thereby cleaning the wood chips on the surface of the plate in advance;

[0034] The cam 25 is provided with a plurality of slots 20 for slidingly connecting the cam 25 to the mounting groove 20, and a retractable spring 21 is fixedly provided between the cam 25 and the mounting groove 20. A sawtooth bar 10 for controlling the rotation of the cam 23 is fixedly installed on one side of the detection platform 1 (the sawtooth bar 10 is composed of a long plate and a plurality of groups of saw teeth, and the plurality of groups of saw teeth are evenly spaced on the long plate, and each group of saw teeth can control the rotation of the cam 26 by a quarter of a circle). During the movement of the cam 26, the cooperation between the sawtooth bar 10 and the arcuate teeth 25 can control the cam 26 to rotate a quarter of a circle after moving for a period of time, so as to switch the bristles 15 and avoid using one group of bristles 15 all the time, which affects the cleaning effect. After the detection is completed, when the control mounting frame 2 is reset, the sawtooth bar 10 will squeeze the arcuate teeth 25 to slide into the mounting groove 20, so that the cam 26 does not rotate during the reset process.

[0035] A limiting assembly for limiting the rotating rod 26 is provided in the slider 28, and the limiting assembly includes an annular block 29 fixedly sleeved on the outside of the rotating rod 26, and a plurality of arc-shaped spring plates 27 are fixedly installed at equal intervals on the outside of the annular block 29. A cavity is opened in the slider 28, and an annular plate 30 is fixedly installed in the cavity. A plurality of arc-shaped protrusions 24 corresponding to the positions of the arc-shaped spring plates 27 are fixedly installed on the inside of the annular plate 30 at equal intervals. During the detection process, when the motor 9 controls the movement of the mounting frame 2, the rotating rod 26 can be limited by the cooperation of the arc-shaped protrusions 24 and the arc-shaped spring plates 27, so that each time the rotating rod 26 rotates to switch the bristles 15, it can be ensured that the bristles 15 are in contact with the surface of the plate for cleaning.

[0036] The cleaning assembly is installed on one side of the slider 28, and a rotating member for controlling the extension and retraction of the cleaning assembly is fixedly installed on the slider 28. The cleaning assembly includes a fixed cylinder 16 fixedly installed on one side of the slider 28, and a connecting port 33 is opened on one side of the fixed cylinder 16. The mounting plate 22 is abutted against the connecting port 33. The thickness of the mounting plate 22 is greater than the height of the connecting port 33, and the length of the mounting plate 22 is greater than the width of the connecting port 33. A rotating shaft 8 is rotatably installed in the fixed cylinder 16, and multiple rotating frames 32 are fixedly installed on the outer side of the rotating shaft 8. One end of the rotating shaft 8 passes through one of the sliding ports 3 and is fixedly sleeved with a gear ring 5. A serrated plate 6 meshing with the gear ring 5 is fixedly installed on one side of the detection platform 1. During the detection process, when the motor 9 controls the installation frame 2 to move, the gear ring 5 cooperates with the serrated plate 6 to make the rotating shaft 8 drive the rotating frame 32 to rotate, and the brush 15 that has just been cleaned is patted and cleaned, so as to avoid wood chips being mixed in the brush 15 and affecting the next cleaning effect.

[0037] As a further technical solution of the present invention, the rotating part includes a disc 14 fixedly connected to the slider 28, and an annular groove is provided on one side of the disc 14. The annular groove is composed of a first arc groove 13, a second arc groove 12 and a horizontal groove 11 which are interconnected. One end of the mounting plate 22 is fixedly connected to a sliding rod 18 which is slidably connected to the annular groove. In the process of controlling the rotation of the rotating rod 26, the bristles 15 that have just been cleaned can be controlled to move to the fixed cylinder 16 through the cooperation of the annular groove and the connecting spring 31 to clean the bristles 15.

[0038] As a further technical solution of the present invention, the fixed cylinder 16 is composed of two arc-shaped shells, one of which is fixedly connected to the slider 28, and a rotating block 34 is fixedly installed on both arc-shaped shells. The two rotating blocks 34 are rotatably connected by a spring shaft. This rotating structure is a prior art and will not be described in detail here. In the presence of external force, the fixed cylinder 16 can be rotated to open the fixed cylinder 16 to clean the wood chips inside. In the absence of external force, the fixed cylinder 16 is in a closed state.

[0039] Working principle: During random inspection, the wood board to be inspected is placed on the inspection table 1, and the motor 9 is started to drive the threaded rod 7 to rotate, and the threaded rod 7 drives the mounting frame 2 to move, and the mounting frame 2 drives the slider 28 to slide in the sliding mouth 3. When the slider 28 moves, it drives the rotating rod 26, the fixed cylinder 16 and the disc 14 to move;

[0040] The rotating rod 26 drives the cross mounting frame 17 to move when it moves, and the cross mounting frame 17 drives the brush 15 to move through the mounting plate 22, so as to clean the wood chips on the surface of the board in advance, and then the detection probe 4 can detect the cleaned board;

[0041] When the rotating rod 26 is moving and the extruded arc-shaped teeth 25 are not in contact with the sawtooth bar 10, the rotating rod 26 can be limited by the cooperation of the arc-shaped protrusion 24 and the arc-shaped spring plate 27, so that each time the rotating rod 26 rotates to switch the bristles 15, it can be ensured that the bristles 15 are in contact with the surface of the plate for cleaning.

[0042] When the rotating rod 26 is moving, the arc-shaped teeth 25 are squeezed to contact the sawtooth bar 10, which can make the rotating rod 26 rotate a quarter of a circle, and the bristles 15 are switched to avoid using one set of bristles 15 all the time, which affects the cleaning effect. After the detection is completed, the motor 9 is started to reverse and control the mounting frame 2 to reset. During this process, the sawtooth bar 10 squeezes the arc-shaped teeth 25 to slide into the mounting groove 20, so that the rotating rod 26 does not rotate during the reset process.

[0043] When the rotating rod 26 drives the cross mounting frame 17 to rotate, the cross mounting frame 17 drives the slide rod 18 to slide in the annular groove through the mounting plate 22. The bristles 15 that have just finished cleaning slide from the first arc groove 13 through the second arc groove 12 to the horizontal groove 11. Then, the slide rod 18 is pushed to slide in the horizontal groove 11 by the action of the connecting spring 31 until it slides to the connection between the horizontal groove 11 and the first arc groove 13. At this time, the bristles 15 that have finished cleaning are pushed into the fixed cylinder 16, and the mounting plate 22 on one side of the bristles 15 abuts against the connecting port 33.

[0044] The fixed cylinder 16 drives the rotating shaft 8 to move during the movement. Through the cooperation of the gear ring 5 and the serrated plate 6, the rotating shaft 8 can drive the rotating frame 32 to rotate, and the bristles 15 that have just been cleaned are patted and cleaned to avoid wood chips mixed in the bristles 15, which affects the cleaning effect next time.
