Description

Technical Field

[0001] The utility model relates to the technical field of furniture manufacturing, in particular to a positioning device for cutting furniture plates. Background Art

[0002] Furniture boards are used in furniture manufacturing. During the board processing, the size of the boards needs to be cut according to actual conditions for easy transportation or direct use. Before cutting, the cutting position of the boards must be determined, and the boards must be measured and marked, and then cut using a cutting machine. In the prior art, auxiliary positioning devices for board cutting are widely used, such as patent CN212020748U, a marking device for cutting bamboo and wood boards, which discloses fixing a marking pen at the bottom end of a threaded rod. After the marking pen is positioned, the marking pen is driven by a motor, a lead screw, and a first slider to mark the surface of the bamboo and wood board, thereby achieving board cutting positioning and marking. However, before marking, the support plate and the top plate need to be moved along the first slide groove, and then the marking pen on the U-shaped block needs to be moved along the second slide groove on the top plate to mark. At the same time, measurement operations are still required before marking positioning, which is not conducive to further improving the processing rate. Utility Model Content

[0031] The utility model relates to a positioning device for cutting furniture plates, comprising a workbench 1 for placing plates, a lifting and pressing plate component 2 for fixing plates, a right-angle top block 3 for limiting the position of plates is arranged on the workbench 1, one corner of the plates abuts against the inner side of the right-angle top block 3, and the lifting and pressing plate component 2 is arranged above the plates placed on the workbench 1. As an embodiment, the right-angle top block 3 is arranged at the upper left corner of the workbench 1 and the right-angle opening of the right-angle top block 3 faces the center of the plate workbench 1, and the lifting and pressing plate component 2 is arranged in the space above the center of the workbench 1. Furthermore, a support frame 10 is arranged above the workbench 1, and the lifting and pressing plate component 2 is installed on the support frame 10.

[0032] Specifically, a capacitive digital caliper 4 is also installed on the workbench 1. The capacitive digital caliper 4 is arranged outside the right-angle top block 3. The capacitive digital caliper 4 is parallel to the right-angle side direction of the right-angle top block 3. The capacitive digital caliper 4 takes the position where the right-angle top block 3 is located as the starting position, and the position where one corner of the plate rests on the inner side of the right-angle top block 3 is the zero scale point. The capacitive digital caliper 4 includes a fixed scale 40 installed on the workbench 1 and a movable caliper 41 slidably connected to the fixed scale 40. The fixed scale 40 includes a static grid of a capacitive grid sensor and a ruler body with a static grid installed. The movable caliper 41 includes a sliding housing, a digital display is arranged on the top of the sliding housing, a capacitive digital caliper circuit board is arranged in the sliding housing, the capacitive digital caliper circuit board includes a movable grid of a capacitive grid sensor and a control calculation board with a movable grid installed, and the digital display is electrically connected to the capacitive digital caliper circuit board. The capacitive digital caliper adopts a capacitive sensor to convert the mechanical displacement into an electrical signal. The control operation board that receives the electrical signal displays the size of the obtained mechanical displacement on a digital display after a series of transformations and operations.

[0033] As an implementation mode, a dehumidification bag is removably placed in the sliding shell, and the dehumidification bag can be replaced regularly to keep the sliding shell dry, which is beneficial to ensure the measurement accuracy of the capacitive sensor during long-term use and reduce the impact of the humid environment on the measurement accuracy.

[0034] Furthermore, a linear transmission component 5 is arranged parallel to the side of the fixed scale 40 away from the plate, a moving block 50 is installed on the linear transmission component 5, a laser scriber 51 is installed on the top of the moving block 50, and a line of light emitted by the laser scriber 51 is used to mark and position the furniture plate 6 to indicate the cutting position. One side of the moving block 50 is connected to the movable caliper 41, so that the movable caliper 41 is driven to move when the moving block 50 moves. Furthermore, the moving block 50 is connected to the movable caliper 41 through a connecting rod 52. During use, the moving block 50 drives the movable caliper 41 to move. When the staff observes that the value displayed on the digital display corresponds to the required cutting size, the linear transmission component 5 stops driving, so that the moving block 50 remains in the cutting position, and the light emitted by the laser scriber 51 is irradiated on the furniture plate to complete non-contact marking and positioning, which is convenient for the subsequent cutting operation using cutting equipment.

[0035] It can be understood that the linear transmission component 5 adopts a linear guide rail or an electric push rod, so that the moving block 50 can reciprocate along the linear direction.

[0036] Further, the lifting platen component 2 includes a driving device 20, the output shaft of the driving device 20 is equipped with a pressure plate, the pressure plate is arranged to face the workbench 1, and a pressure sensor 22 is installed in the pressure plate. It can be understood that the driving device 20 can be an electric cylinder, a pneumatic cylinder or a hydraulic cylinder to realize the up and down movement of the pressure plate.

[0037] As an embodiment, a connecting bracket 24 is further provided between the pressure plate and the output shaft of the driving device 20, and the connecting bracket includes a triangular connecting rod 240, and the triangular connecting rod 240 is connected to one side of the square tube ring 241, and the pressure plate is arranged on the other side of the square tube ring 241. The cross-section of the square tube ring 241 is square, so that when the pressure plate is pressed down, the square tube ring disperses the downward pressure of the output shaft to the pressure plate, thereby effectively protecting the furniture panel.

[0038] As an embodiment, the pressure plate includes an upper plate 210 and a lower plate 211, and a pressure sensor 22 and a plurality of buffer springs 23 are arranged between the upper plate 210 and the lower plate 211. Furthermore, a controller is also arranged on one side of the workbench 1, and the pressure sensor 22, the drive device 20, the linear transmission component 5, and the laser scriber 51 are electrically connected to the controller respectively. Before the device is used, the pressure parameter is preset on the controller. When the pressure value obtained by the pressure sensor reaches the pressure parameter, the drive device 20 stops pressing down to complete the fixing of the furniture board. After the cutting is completed, the drive device 20 drives the pressure plate to move up. Furthermore, a plurality of buffer springs 23 are arranged around the pressure sensor 22. It can be understood that the pressure sensor 22 is arranged at the center of the upper plate 210, and a plurality of buffer springs 23 are arranged around the upper bottom plate 210.

[0039] As an implementation mode, a protective pad for protecting the board is arranged on the outer side of the lower plate 211. Furthermore, the protective pad is arranged as a rubber pad, which is more economical and durable, and can effectively prevent the pressure plate from causing scratches and damage to the furniture board during the process of pressing down and fixing the board.

[0040] As an embodiment, the workbench 1 is formed with a vertical mounting channel 6, and the vertical mounting channel 6 and the right-angle top block 3 are respectively located on both sides of the lifting and lowering plate component 2, and a lifting device 60 is arranged in the vertical mounting channel 6, and the top of the lifting device 60 is arranged as a universal ball platform 61, and the universal ball platform 61 includes a lifting plate, and a plurality of split ball mesh belts 610 are installed on the lifting plate, and the split ball mesh belts 610 are recessed with ball mounting grooves 612, and the ball mounting grooves 612 are installed with universal balls 611, and the universal balls 611 can roll in the ball mounting grooves 612; further, the ball mounting grooves 612 are also formed with mounting square grooves for facilitating the placement of mounting covers 613, and the mounting cover 613 is formed with arc-shaped mounting holes corresponding to the universal balls 611, so that the top of the universal balls 611 is exposed from the arc-shaped mounting holes. When in use, the universal ball platform 61 rises under the drive of the lifting device 60, so that the top of the universal ball 611 is higher than the plane of the workbench 1. After the user places the plate on the workbench 1, the back of the plate contacts the universal ball 611. The user only needs to push the plate to push the plate to the right-angle top block 3 under the action of the universal ball 611, so that one corner of the plate rests on the inner side of the right-angle top block 3. Then the universal ball platform 61 descends, and the back of the plate is placed flat on the workbench 1. The driving device 20 drives the pressure plate to press down and fix the plate, and the linear transmission component 5 drives the moving block 50 to move. When the value displayed on the digital display corresponds to the required cutting size, the moving block 50 remains in the cutting position, and the laser scriber 51 synchronously realizes positioning and marking.

[0041] As an implementation method, a contact switch is provided inside the right-angle top block 3. When the furniture plate is against the inside of the right-angle top block 3, the contact switch is triggered, and the lifting device 60 drives the universal ball platform 61 to descend, so that the back side of the plate is placed flat on the workbench 1, and then the driving device 20 drives the pressure plate to press down and fix the plate. Specifically, the lifting device 60 can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder to realize the up and down movement of the universal ball platform 61.

[0042] As an implementation mode, the workbench 1 has universal wheels at the bottom, so that the user can move the workbench 1 according to usage requirements.
