Description
Technical Field
[0001] The utility model relates to the technical field of plate edge banding equipment, in particular to a plate precision positioning device for a plate edge banding machine. Background Art
[0002] In the production of furniture made from boards, it is necessary to stick edge banding tape on the cut surface of the board for edge banding. The edge banding machine in the prior art places the board on the chain conveyor belts arranged on the left and right sides of the table, and cooperates with the rollers pressed on the top of the board to move the board in the left and right directions to complete the milling and edge banding of the side of the board. In the actual production process, for boards with consistent side shape throughout the side, the milling and edge banding processing do not require high accuracy in the left and right position of the board. However, for the case where the side shape of the board is inconsistent, for example, the middle part of the side of the board has a C-shaped or J-shaped groove, the position of the board is positioned by the conveying stroke of the chain conveyor. Due to the movement gap of the chain conveyor, etc., the error is large, resulting in insufficient accuracy in the shape position of the side of the board. Utility Model Content
[0003] In view of the above problems, the utility model provides a plate precision positioning device for a plate edge banding machine, which provides precise positioning for the plate during translation processing, thereby ensuring the processing accuracy of the plate.

[0007] Furthermore, the mobile position detection device includes an encoder, which is mounted on a gear or a motor, and detects the left-right positioning of the top plate by measuring the rotation angle of the gear. The servo motor has its own encoder.
[0008] Furthermore, the mobile position detection device includes a displacement sensor, and the displacement sensor is installed on the plate precision positioning device or the edge banding machine. The mobile position detection device detects the left and right direction positioning of the plate precision positioning device.
[0009] Furthermore, the top plate is slidably arranged on the mounting frame along the up-down direction, and the top plate is connected with up-down linear drive devices to provide power for the up-down movement of the top plate.
[0010] Furthermore, the top plate is slidably arranged on the mounting frame along the front-rear direction, and the top plate is connected to a front-rear linear drive device to provide power for the front-rear movement of the top plate.
[0011] Furthermore, a pressure wheel for pressing the plate is arranged above the plate conveying device, and the front end of the top plate is located below the pressure wheel.
[0012] Furthermore, the top plate is rotatably arranged on a mounting frame, and the top plate is switched between two positions of leaning against the plate and not interfering with the left and right movement of the plate by rotating.

[0027] As an embodiment, the linear drive device 32 includes a motor 321, a gear 322, and a rack 323. The rack 323 is fixedly arranged on the edge banding machine 1 along the left-right direction. The motor 321 is mounted on the mounting frame 34. The gear 322 is connected to the driving shaft of the motor 321, and the gear 322 is meshed with the rack 323. As other embodiments, the linear drive device 32 can also be a linear drive device in the prior art such as a cylinder, a hydraulic cylinder, an electric telescopic rod, a synchronous belt drive, a screw drive, etc.
[0028] As an embodiment, the mobile position detection device includes an encoder, which is installed on the gear 322 or the motor 321. The encoder detects the left and right positioning of the top plate by measuring the rotation angle of the gear. As an implementation, the motor 321 is a servo motor with an encoder, so it is not shown in the drawings. In addition, the motor 521 can also be a motor in the prior art such as a hybrid servo, a stepper motor, etc.
[0029] As another embodiment, the mobile position detection device includes a displacement sensor, which is installed on the plate precision positioning device 3 or the edge banding machine 1, and the mobile position detection device detects the left and right positioning of the plate precision positioning device 3. The displacement sensor includes but is not limited to a magnetic scale, a grating scale, etc.
[0030] As a more preferred implementation scheme, the top plate 31 is slidably arranged on the mounting frame 34 in the up-down direction. Specifically, a second vertically arranged slide rail 343 is installed on the mounting frame 34. The top plate 31 is installed on the second slider 344. The second slider 344 and the second slide rail 343 slide together to realize the up-down sliding of the top plate. As other implementation schemes, the up-down sliding can also be realized by other linear sliding structures in the prior art, such as an optical axis and a linear bearing. The top plate 31 is connected with an up-down linear drive device 35 to provide power for the up-down movement of the top plate 31. The up-down linear drive device 35 includes but is not limited to a cylinder, an electric telescopic rod, a hydraulic cylinder, a motor-driven screw nut pair, etc. By moving the top plate up and down, the top plate is moved down to contact the left end of the plate when precise positioning is required, and the top plate is moved up to avoid interference between the top plate and the plate when precise positioning is not required. In addition, the position of the top plate 31 can be kept unchanged. After the plate is processed, the plate is directly removed and then the top plate is moved to the right to return to its original position.
[0031] As a more preferred embodiment, the top plate 31 is slidably arranged on the mounting frame 34 along the front-back direction, and the top plate 31 is connected to a front-back linear drive device 36 to provide power for the front-back movement of the top plate 31. Specifically, the top plate 31 is mounted on a third slider 345, and a third slide rail 346 arranged along the front-back direction is installed on the mounting frame 34. The third slider 345 and the third slide rail 346 slide together to realize the up and down sliding of the top plate. As other embodiments, the up and down sliding can also be realized by other linear sliding structures in the prior art, such as an optical axis and a linear bearing; the front-back linear drive device 36 includes but is not limited to a cylinder, an electric telescopic rod, a hydraulic cylinder, a motor-driven screw nut pair, etc. By moving the top plate forward and backward, when precise positioning is required, the top plate is moved down to contact the left end of the plate, and when precise positioning is not required, the top plate is moved forward to avoid interference between the top plate and the plate.
[0032] A pressing wheel 21 for pressing the plate is arranged above the plate conveying device 2, and the front end of the top plate 31 is located below the pressing wheel 21. Specifically, the pressing wheel 21 is connected to a lifting device to control its lifting and lowering. After the plate is placed on the plate conveying device 2, the pressing wheel drops down and presses on the plate, thereby ensuring that the friction between the plate and the plate conveying device drives the plate to move. The plate processing parts such as milling and edge banding are located behind the pressing wheel, and the positions of the milling cutter 5, the edge banding belt fitting wheel 6, etc. are located behind the plate. The top plate extends under the pressing wheel to be as close to the plate processing position as possible, thereby ensuring the positioning accuracy of the plate processing position.
[0033] As another embodiment, the top plate is adjusted in its front and rear position by moving forward and backward, so that the top plate can switch between two front and rear positions: being located below the pressure wheel or not; and the top plate can switch between two up and down positions: being located on the left side of the plate or not by moving up and down. Thus, the top plate can be located both on the left side of the plate and below the pressure wheel when working. When the top plate returns to the zero position, neither the pressure wheel nor the plate will interfere with the movement of the top plate.
[0034] Furthermore, the top plate 31 is rotatably mounted on the mounting frame 34. The top plate 31 is switched between two positions, that is, against the plate and not interfering with the left-right movement of the plate, by rotating. The top plate 31 is connected to a motor to provide power for its rotation. The top plate 31 can be switched between two positions, that is, located on the left side of the plate and not interfering with the leftward movement of the plate. The switching methods include, but are not limited to, translating the top plate 31 to move the position, rotating the top plate 31, and the like.
[0035] The specific use process of one embodiment of the utility model is as follows:
[0036] The plate is placed on the plate conveying device 2, and the plate conveying device drives the plate to move from right to left. During this process, the plate is pressed by the pressure wheel 21 to make the plate and the plate conveying device move synchronously. The plate moves to the right side of the top plate 31 and pushes the top plate 31 to move to the left. During the movement, the motor 321 always gives the top plate 31 a rightward force to make the top plate 31 and the plate fit more closely. The thrust of the plate is greater than the resistance given by the motor 321. In the process of the plate moving to the left, the encoder or displacement sensor records the position of the plate in real time and transmits it to the controller of the edge banding machine, thereby providing accurate position information for the edge banding machine to perform milling, edge banding and other processing on the plate. After completing the processing with high precision requirements, the front and rear linear drive devices 36 drive the top plate 31 to move forward to exit in front of the pressure wheel, and then the top plate 31 is lifted upward by the upper and lower linear drive devices 35. The top plate 31 and the plate do not interfere with each other. The plate continues to move for processing or is directly removed. The top plate 31 moves to the right to its original position driven by the motor 321 of the linear drive device 32 to wait for the next plate to be precision processed.
[0037] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, this does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
