Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, and more specifically, to a sheet metal edge banding in-place detection and docking device. Background Technology

[0002] Edge banding machines are a type of woodworking machinery. As the name suggests, they are used to band the sides of wood panels, automating the traditional manual process. The process includes many steps such as conveying, gluing, cutting, front and back trimming, top and bottom trimming, top and bottom fine trimming, top and bottom scraping, and polishing. In the edge banding process, the edge banding tape needs to wrap around the entire board. The tape is automatically fed by a feeding mechanism. After the edge banding is completed, the feeding mechanism needs to stop. Currently, the length of edge banding tape needed for the entire board's circumference is calculated, and then the feeding length of the tape feeding machine is set. However, due to errors in the calculation of the entire board's side length, the length of the edge banding tape fed in this way does not match the length of the board's side. This often results in overlapping ends or gaps between the edge banding tape after banding, leading to poor edge banding quality. Therefore, overcoming the shortcomings of the existing technology is a problem that urgently needs to be solved in this technical field. Utility Model Content

[0003] This utility model provides a device for detecting and docking edge banding tape in place, which aims to improve the current method of calculating the length of edge banding tape needed for the entire circumference of the board and then setting the feeding length of the tape feeder. However, due to errors in the calculation of the entire side of the board, the length of the edge banding tape being fed does not match the length of the side of the board. This often results in the edge banding tape overlapping at the beginning and end or gaps between the two after edge banding is completed, leading to poor edge banding quality.

[0004] To achieve the above objectives, this utility model provides a device for detecting and connecting edge banding of sheet metal in place, the specific technical solution of which is as follows:

[0005] In one embodiment, a sheet metal edge banding tape positioning and detection device includes a mounting frame. A positioning mechanism is provided on one side of the mounting frame to position the sheet metal to be processed. A detection mechanism is provided on the mounting frame, including a second fixing member fixed to one side of the mounting frame. A sensor is fixed on the second fixing member. The signal emitted by the sensor can illuminate the edge banding tape on the sheet metal. When the edge banding tape is properly applied to the sheet metal, the sensor can receive the corresponding signal and then send information to the edge banding tape conveyor to stop the conveyor, thereby stopping the edge banding tape supply.

[0006] In one embodiment, the sensor emits a signal that illuminates the edge banding strip on the underside of the bottom surface of the board.

[0007] In one embodiment, the positioning mechanism includes a bottom positioning unit, which includes a first fixing member fixed to one side of the mounting frame. A bottom positioning member is rotatably mounted on the lower side of the first fixing member, and the bottom surface of the plate is placed on the bottom positioning member to achieve positioning of the bottom surface of the plate.

[0008] In one embodiment, the bottom positioning element is conical or cylindrical.

[0009] In one embodiment, the positioning mechanism further includes a side positioning unit, which includes a side positioning shaft rotatably mounted on a mounting bracket. The side positioning shaft abuts against the side edge of the plate to achieve positioning of the distance between the side of the plate and the sensor.

[0010] In one embodiment, there are two side positioning shafts, which are respectively located on both sides of the bottom positioning unit.

[0011] In one embodiment, a lifting mechanism is provided on the lower side of the mounting frame. The lifting mechanism includes a driving component that can push the mounting frame to move up and down, thereby enabling the mounting frame to drive the bottom positioning unit to move up and down, thereby realizing the adjustment of the reference point on the side of the plate illuminated by the sensor.

[0012] In one embodiment, the mounting frame is provided with a contouring mechanism, which includes a third fixing member. A rotating shaft is rotatably mounted on one side of the third fixing member. The rotating shaft is fixed to a connecting plate for fixing the device and the entire edge banding machine. An elastic member is connected to one side of the third fixing member, and a connecting shaft is connected to the other side of the elastic member. The connecting shaft is fixed to the mounting frame. Under the elastic force of the elastic member, the device can always be in close contact with the side edge of the board, realizing the contouring of the board during edge banding.

[0013] In one embodiment, the elastic element is a spring.

[0014] The beneficial effects of this embodiment are:

[0015] 1. By setting a positioning mechanism on one side of the board, the board is positioned. Then, an inspection mechanism is set on one side of the board. The sensor on the inspection mechanism emits a signal that can illuminate the edge banding tape on the board. When there is no edge banding tape on the side of the board, the sensor signal is not blocked by the edge banding tape and will be emitted further. When the edge banding tape on the side of the board is finished, the sensor signal illuminates the edge banding tape, and the edge banding tape blocks the sensor signal. At this time, the sensor signal is emitted for a shorter distance. The sensor will then send a signal to the tape feeder, and the tape feeder will stop feeding. The signal will be blocked when the beginning and end of the edge banding tape just touch, and the tape feeder will stop at the exact moment. Therefore, the edge banding tape feeding is very accurate and there will be no overlap or insufficient feeding, which greatly improves the edge banding quality.

[0016] 2. By setting up a lifting mechanism, when the board is long, the height of the board will change during the edge sealing process. This will cause the height position of the reference point on the side of the board where the sensor transmits the signal to change, resulting in inaccurate signal. The lifting mechanism can push the height of one side of the board to change, thereby adjusting the height position of the reference point on the side of the board where the sensor transmits the signal to change, so that the sensor transmits the signal to the same reference height position on the side of the board, thus improving the accuracy of inspection.

[0017] 3. By setting up a contouring mechanism, the board material is always in close contact with the positioning mechanism during the edge banding process, resulting in a tight and secure edge banding. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] The technical solutions provided by the embodiments of this utility model are described below with reference to the accompanying drawings.

[0037] Please see Figure 1 , Figure 2 and Figure 3An embodiment of this utility model provides a board edge banding in place detection and docking device, including a mounting frame 100, which is composed of a board. A positioning mechanism 200 is provided on the side of the mounting frame 100, which is used to position the board to be processed.

[0038] Please see Figure 2 , Figure 5 and Figure 6 Specifically, the positioning mechanism 200 includes a bottom positioning unit 210, which includes a first fixing member 211. The first fixing member 211 is L-shaped and is fixed to the middle of the mounting bracket 100 by bolts. A bottom positioning member 212 is rotatably mounted on the lower side of the first fixing member 211. The bottom surface of the plate 600 is placed on the bottom positioning member 212 to achieve bottom positioning of the plate 600, thereby achieving height positioning of the plate 600. Preferably, the bottom positioning member 212 is conical or cylindrical. Specifically, when the bottom positioning member 212 is conical (e.g., ...), ... Figure 5 As shown in the figure, the large end of the bottom positioning component 212 is provided with a short cylindrical section. The outer cylindrical surface of this section of cylinder contacts the bottom surface of the plate 600. The remaining part of the bottom positioning component 212 is a conical surface. In this way, the remaining bottom positioning component 212 cannot contact the bottom surface of the plate 600, reducing frictional resistance and allowing the plate 600 to move forward more smoothly. When the bottom positioning component 212 is a cylinder (not shown in the figure), the cylinder is tilted so that the high point of the cylinder abuts against the bottom end of the plate 600. Of course, the bottom positioning component 212 can also be made of other structural components, as long as it can support the plate 600. Examples will not be given here.

[0039] Please see Figure 2 , Figure 5 and Figure 6 In addition, the positioning mechanism 200 also includes a side positioning unit 220, which includes a side positioning shaft 221. The side positioning shaft 221 is rotatably mounted on the mounting bracket 100. There are two side positioning shafts 221, which are respectively located on both sides of the bottom positioning member 212. The outer cylindrical surface of the side positioning shaft 221 abuts against the side of the plate 600 to achieve positioning of the side of the plate 600. Then, when the plate 600 moves forward, it contacts the bottom positioning member 212 and the two side positioning shafts 221 to achieve positioning of the plate 600.

[0040] Please see Figure 4 , Figure 6 and Figure 7It should be noted that a detection mechanism 300 is provided on one side of the mounting frame 100. The detection mechanism 300 includes a second fixing member 310, which is fixed to one side of the mounting frame 100 by bolts. A sensor 320 is fixed on the second fixing member 310. The sensor 320 can be a photoelectric sensor, a proximity sensor, an ultrasonic sensor, an image recognition sensor, etc. The signal emitted by the sensor 320 can illuminate the edge banding tape 610 on the board 600. When the edge banding tape 610 on the board 600 is in place, the sensor 320 can receive the corresponding signal and then send information to the conveyor of the edge banding tape 610 to stop the conveyor of the edge banding tape 610, thereby stopping the feeding of the edge banding tape 610.

[0041] It should be noted that the signal emitted by sensor 320 illuminates the edge banding 610 on the underside of the bottom surface of the sheet 600 (e.g., Figure 8 (The area indicated by the dotted line) When there is no edge banding tape on the side of the board 600, the sensor signal is not blocked by the edge banding tape and will be transmitted over a longer distance. After the edge banding tape is applied to the side of the board 600, the signal of the sensor 320 shines on the edge banding tape, and the edge banding tape blocks the signal of the sensor 320. As a result, the signal transmitted by the sensor 320 is shorter. At this time, the sensor 320 will send a signal to the tape feeder, and the tape feeder will stop feeding. The signal will be blocked only when the beginning and end of the edge banding tape just touch, and the tape feeder will stop at the exact moment. Therefore, the edge banding tape feeding is very accurate and there will be no overlap or insufficient feeding, which greatly improves the edge banding quality.

[0042] Please see Figure 4 , Figure 5 and Figure 6 Specifically, a lifting mechanism 400 is provided on the lower side of the mounting frame 100. The lifting mechanism 400 includes a driving component 410, which can be a cylinder, an electric push rod, etc. The piston rod end of the driving component 410 is fixedly connected to the mounting frame 100, so that the driving component 410 can push the mounting frame 100 to move up and down, and the mounting frame 100 can drive the bottom positioning unit 210 to move up and down. When the length of the board is long, the height of the board will change during the edge sealing process, which will cause the height position of the reference point on the side of the board where the signal emitted by the sensor 320 is irradiated to change, resulting in inaccurate signal. By using the driving component 410 of the lifting mechanism 400 to push the height of one side of the board to change, the height position of the reference point on the side of the board where the signal emitted by the sensor 320 is irradiated can be adjusted, so that the signal emitted by the sensor 320 is irradiated at the same reference height position on the side of the board, thereby improving the accuracy of inspection.

[0043] Please see Figure 3 , Figure 4 and Figure 6The mounting frame 100 is equipped with a contouring mechanism 500, which includes a third fixing member 510. A rotating shaft 520 is rotatably mounted on one side of the third fixing member 510, allowing the third fixing member 510 to rotate around the axis of the rotating shaft 520. The rotating shaft 520 is fixed to a connecting plate 700 used to fix the device and the entire edge banding machine together. An elastic member 530 is connected to one side of the third fixing member 510; the elastic member 530 is preferably a spring, but rubber strips or other elastic parts can also be used. A connecting shaft 540 is connected to the other side of the elastic member 530 and is fixed to the mounting frame 100. During the edge sealing process, the board pushes the mounting bracket 100 backward via the side positioning shaft 221. After the mounting bracket 100 is pushed, it drives the third fixing member 510 to move backward. Then, the third fixing member 510 rotates backward around the rotating shaft 520. At this time, the elastic member 530 on the third fixing member 510 becomes longer after being pushed backward, and thus the tension increases. As a result, the elastic member 530 gives the mounting bracket 100 a forward push, so that the side positioning shaft 221 on the mounting bracket 100 is always in close contact with the side of the board. At the same time, the mounting bracket 100 can rotate around the piston rod axis of the driving member 410, so that the board 600 can always be in contact with the positioning mechanism 200 during the edge sealing process.

[0044] It should be noted that the motion state and trajectory of each mechanism in this device can be automatically controlled by CNC program or PLC programming, and automatic start-stop and automatic operation can be achieved in conjunction with position switches. The above-mentioned programs and programming are common knowledge to those skilled in the art, so they will not be described in detail here.

[0045] The specific model and specifications of sensor 320 and drive unit 410 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0046] The power supply and operating principle of the sensor 320 and the drive unit 410 are clear to those skilled in the art and will not be described in detail here.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
