Description

After the bonding process is completed, such composite panels will inevitably have grooves or open edges. In order to ensure structural performance and sealing, filling or sealing is required. The current gluing process is mainly based on manual gluing by dipping glue. This method is not only inefficient, but the quality of gluing is significantly affected by human factors such as the operator's proficiency and working conditions, resulting in poor gluing consistency and low yield. In addition, in order to ensure that the gluing effect meets the standards, a lot of time needs to be invested in production process control and quality inspection, further increasing production costs and management complexity.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Embodiment 1

[0026] like Figure 1-10 As shown, the present application relates to an adaptive edge banding and gluing device, which comprises: a machine 1 in the shape of a rectangular parallelepiped; a conveyor belt 16 is arranged inside the machine 1, and the conveyor belt 16 is used to transport the composite board from the loading end to the unloading end; an electric control box 3 is arranged on one side of the machine 1.

[0027] In order to facilitate edge sealing of the composite board, the composite board is preferably placed vertically on the conveyor belt 16; after the bonding process, the composite board will leave grooves or open edges, which must be filled or sealed. The vertical placement allows the glue to flow along the direction of gravity, which can improve the filling efficiency of the grooves or edges; vertically placing the composite board can also make full use of the space above the machine 1, making the equipment structure more compact and saving floor space.

[0028] A first clamping plate 11 and a second clamping plate 12 are symmetrically arranged on the top of the conveyor belt 16 along the width direction. The first clamping plate 11 and the second clamping plate 12 have the same structure.

[0029] Taking the first clamping plate 11 as an example, a threaded connection hole is provided at the bottom of the feeding end of the first clamping plate 11, and a connecting through hole is provided at the bottom of the unloading end; a double-threaded screw 14 is threadedly connected to the threaded connection hole, and the thread direction of the double-threaded screw 14 is oppositely arranged from the middle to the two ends; the double-threaded screw 14 is transmission-connected to the first motor 13, and the first motor 13 is installed on the side wall of the machine 1, and is used to drive the double-threaded screw 14 to rotate through the first motor 13, thereby making the first clamping plate 11 and the second clamping plate 12 approach or move away from each other, thereby adjusting the distance between the first clamping plate 11 and the second clamping plate 12. The connecting through hole is slidably connected to a limit rod 15, which is used to limit the first clamping plate 11 and the second clamping plate 12, ensure the stability of the sliding of the first clamping plate 11 and the second clamping plate 12, and avoid shaking, offset, etc. when adjusting the distance or limiting the composite plate; A rotating cylinder 111 is rotatably mounted on the first clamping plate 11. After the first clamping plate 11 and the second clamping plate 12 limit the composite plate, the composite plate can continue to move along the material conveying direction driven by the conveyor belt 16; the double-threaded screw 14 and the limiting rod 15 are respectively arranged at the upper and lower ends of the material conveying direction to avoid interference with the composite plate.

[0030] An edge sealing component 23 for edge sealing the composite board is also provided on the top of the machine 1; the edge sealing component 23 includes: a bracket 21 fixedly installed on the top of the machine 1, a three-axis movable module 22 installed on the top of the bracket 21, and an edge sealing nozzle 233 installed on the three-axis movable module 22; the three-axis movable module 22 is used to drive the edge sealing nozzle 233 to move in the three directions of X, Y, and Z, so that the edge sealing nozzle 233 can flexibly adjust the edge sealing position and trajectory according to the composite boards of different heights or widths; the position of the edge sealing nozzle 233 can be accurately controlled by the three-axis movable module 22 to achieve high-precision edge sealing operation, which helps to ensure the quality of edge sealing and make the edge sealing glue evenly applied to the edge of the composite board; the three-axis movable module 22 is arranged on the top of the bracket 21 to facilitate adaptation to composite boards of different heights or widths.

[0031] The edge sealing glue nozzle 233 includes: a glue inlet 231, which is connected to the glue box through a connecting pipe. The glue box can be set on one side of the machine 1 or on the top of the three-axis movable module 22. The glue liquid is pumped out from the glue box through a glue pump and transported to the glue inlet 231. How the glue pump pumps the glue liquid from the glue box to the glue inlet 231 is a conventional setting and will not be described in detail in this application.

[0032] The glue outlet end of the glue inlet 231 is connected to a glue nozzle body 232, which is in a cylindrical shape and hollow inside to form a glue flow channel; the glue outlet end of the glue nozzle body 232 is connected to a glue outlet nozzle, which is rotatably connected to the glue nozzle body 232; a glue outlet switch 234 is provided on the glue outlet nozzle; the glue outlet switch 234 is used to open or seal the glue outlet nozzle, thereby controlling the outflow and stop of the glue.

[0033] The glue discharging switch 234 comprises: a rotating circle 2341, a transmission member 2342 is connected to the outer arc surface of the rotating circle 2341, and a cylindrical connecting block is arranged on the bottom surface of the rotating circle 2341; the rotating circle 2341 is coaxially connected to a closing member 2344, the closing member 2344 is composed of a plurality of rotating blocks, one end of two adjacent rotating blocks close to each other is an arc surface, and a sliding groove is provided at the other end of the rotating block, and the sliding groove is slidably connected with the cylindrical connecting block; a cylindrical block is installed on the side of the closing member 2344 away from the rotating circle 2341; the closing member 2344 is coaxially connected to a guide ring 2343, and a waist hole is provided on the guide ring 2343, and the waist hole is slidably connected with the cylindrical block; when the transmission member 2342 rotates, it drives the rotating circle 2341 to rotate, and then drives the plurality of rotating blocks of the closing member 2344 to slide along the waist hole of the guide ring 2343 through the cylindrical connecting block, so that the plurality of rotating blocks move away from each other to form an opening, or move close to each other to close the glue discharging nozzle.

[0034] Among them, when the edge sealing is completed, the glue pump stops supplying glue, but the pressure in the pipeline is not released in time, and the glue liquid will continue to flow out from the glue nozzle that is not completely closed under the action of pressure, forming a tail or residue. The residual glue liquid may drip, which may contaminate the conveyor belt 16, or form irregular glue marks during edge sealing, affecting the appearance and sealing, so the residual glue liquid needs to be processed.

[0035] The glue outlet nozzle includes: an arc-shaped portion 2331 , a straight portion 2332 connected to the arc-shaped portion 2331 , and a contact portion 2333 disposed at the connection between the straight portion 2332 and the arc-shaped portion 2331 .

[0036] When the composite board needs to be edge-sealed with glue, one corner of the top of the composite board is fitted with the contact portion 2333, and the other corner of the top of the composite board is fitted with the inner arc surface of the arc portion 2331; at this time, the glue outlet switch 234 is between the two corners of the composite board and can completely cover the side of the composite board; then turn on the glue outlet switch 234 to seal the edge of the composite board with glue.

[0037] By cooperating with the arc portion 2331 and the straight portion 2332, it is only necessary to adjust the relative position of the composite board and the inner side of the arc portion 2331 to adapt to composite boards of different thicknesses, so that composite boards of different thicknesses can be edge-sealed; in addition, the arc portion 2331 and the straight portion 2332 form a semi-enclosed structure, and the edge-sealing glue cannot be sprayed outside the range of the arc portion 2331 and the straight portion 2332 (that is, the glue can be prevented from being sprayed on the side wall or unintended area of ​​the composite board). By cooperating with the arc portion 2331 and the straight portion 2332, the glue that may overflow can be moved to the middle, to a certain extent. To prevent leakage; for example, when processing a curved composite board, the first clamping plate 11 and the second clamping plate 12 are used to limit the composite board in the width direction of the conveyor belt 16, and then the conveyor belt 16 is started to move the composite board along the conveying direction; when the composite board moves to below the edge sealing nozzle 233, the three-axis moving module 22 drives the glue nozzle to move to the composite board, and when the glue outlet switch 234 is triggered, the glue coating is started, and then the three-axis moving module 22 adjusts the posture of the edge sealing nozzle 233 (such as height, lateral movement, etc.) according to the curvature of the composite board, so that the glue nozzle is always in contact with the composite board to ensure the edge sealing effect.

[0038] The arc portion 2331 is composed of a shell 23315 and an arc piece 23316 installed on the inner side of the shell 23315. A threaded block 23311 is installed on the shell 23315. A threaded connection through hole is provided in the middle of the threaded block 23311. An adjusting column 23312 is threadedly connected to the threaded connection through hole. A hexagonal head is provided at the end of the adjusting column 23312 outside the arc portion 2331. An inner hexagonal opening is provided on the hexagonal head, so that the hexagonal head or the inner hexagonal opening can be driven to rotate by a wrench or an inner hexagonal wrench to adjust the depth of the adjusting column 23312, thereby adjusting the curvature of the arc portion 2331. One end of the adjusting column 23312 inside the arc portion 2331 is connected to the arc piece 23316, so that the arc can be adjusted by the adjusting column 23312. shaped piece 23316; an annular connecting structure is also installed on the adjusting column 23312, and the annular connecting structure is connected with a flow regulating piece 23314, and the flow regulating piece 23314 is slidably installed on the arc portion 2331 near the liquid outlet, and the flow regulating piece 23314 is used to close or partially close the nozzle body 232, so as to slightly adjust the amount of glue in the nozzle body 232 output to the glue outlet switch 234; the flow regulating piece 23314 is connected to a reset spring 23313 on the side close to the adjusting column 23312, and the reset spring 23313 is used to push the flow regulating piece 23314 to close the nozzle body 232; in addition, the diameter of the annular connecting structure can be increased or decreased as needed to adjust the moving stroke of the flow regulating piece 23314.

[0039] When the thickness of the composite board is too large or too small and exceeds the adjustable range, the adjustment column 23312 can be rotated according to the thickness of the composite board to adjust the curvature of the arc portion 2331; at the same time, the adjustment column 23312 drives the flow adjustment sheet 23314 to slide, and slightly adjusts the amount of glue that can pass through the nozzle body 232. The curvature of the arc portion 2331 is related to the amount of glue output. Specifically, when the curvature of the arc portion 2331 is larger, it means that the thickness of the composite board that can be carried is larger, and the required amount of glue output increases; conversely, the thickness of the composite board becomes smaller, and the required amount of glue output decreases; thus, the curvature adjustment of the arc portion 2331 and the synchronous adjustment of the glue output can be achieved through a simple mechanical structure, and the structure is simple and does not require a complex processing system.

[0040] An opening is provided on the side wall of the straight portion 2332 facing the arc-shaped portion 2331, and a cavity is provided in the opening, in which a rotating plate 23321 is hinged; a storage capsule 23328 is also installed inside the cavity of the straight portion 2332, and the storage capsule 23328 is connected to the rotating plate 23321; a torsion spring is installed on the connecting shaft between the rotating plate 23321 and the straight portion 2332, and the torsion spring is used to keep the rotating plate 23321 in an open state.

[0041] The glue discharge end of the glue discharge switch 234 is also equipped with an annular glue suction component 23322. The inner side of the annular glue suction component 23322 is provided with a plurality of glue suction ports for sucking glue liquid that may drip from the lower side of the glue discharge switch 234. The annular glue suction component 23322 is connected to the storage capsule 23328 through a pipeline. A one-way valve can be provided between the storage capsule 23328 and the annular glue suction component 23322 to prevent the liquid or gas in the storage capsule 23328 from flowing back to the annular glue suction component 23322.

[0043] When the glue discharge nozzle is fitted with the composite board, the composite board contacts the contact part 2333 through the rotating plate 23321, and the glue pump is ready to start discharging glue; at the same time, the side wall of the composite board contacts the rotating plate 23321 to compress the rotating plate 23321. The rotating plate 23321 squeezes the storage capsule 23328 during the compression process. The storage capsule 23328 drives the partition plate 23325 to slide through the transmission rod 23323, compresses the air in the pressure chamber 23324 toward the piston 23326, and extends the piston rod 23327. The piston rod 23327 drives the transmission part 2342 to rotate, so that the glue discharge switch 234 is turned on to discharge glue, and the edge sealing and gluing work of the composite board is performed. When the edge sealing of the composite plate is completed, the composite plate is separated from the rotating plate 23321, and the torsion spring drives the rotating plate 23321 to automatically reset, thereby driving the storage capsule 23328 to expand and inhale air, causing the annular glue suction member 23322 to inhale air, and sucking the glue liquid that may remain on the glue outlet switch 234 into the storage capsule 23328.

[0044] The edge-sealing glue of the composite board is usually applied with hot melt glue or polyurethane glue. As an optional solution, a diluent or a retarder can be stored in the storage capsule 23328 according to the type of glue to prevent the glue from solidifying in the storage capsule 23328 after the storage capsule 23328 absorbs the glue. A rotating rod 23329 is rotatably installed on the side of the partition 23325 close to the storage capsule 23328, and a stirring blade 23331 is coaxially installed on the rotating rod 23329.

Embodiment 2

[0045] The electric control box 3 has a built-in PLC controller, and a visual camera is installed on the three-axis moving module. The visual camera is electrically connected to the PLC controller through a signal line. The visual camera is used to perform real-time visual detection of the relative position relationship between the composite board and the edge banding nozzle.

[0046] The contact part is equipped with a pressure sensor, which is used to detect the pressure change when the edge banding nozzle contacts the composite board, and is electrically connected to the PLC controller through a signal line to transmit the detection data in real time.

[0047] When the composite plate moves under the edge banding nozzle, the three-axis moving module drives the edge banding nozzle to move along the set trajectory, so that the edge banding nozzle gradually approaches the composite plate; when the pressure value detected by the pressure sensor reaches the manually set threshold, it indicates that a corner of the composite plate has contacted the contact part; subsequently, during the movement of the composite plate, the pressure sensor continuously collects contact pressure data to ensure that the contact part maintains stable contact with the edge of the composite plate; during the gluing process, the visual camera continuously collects information on the surface contour and edge position of the composite plate, and combines the contact pressure data collected by the pressure sensor to complete the composite plate in place detection and posture judgment.

[0048] The three-axis moving module dynamically adjusts the three-axis moving module according to the changes in the edge height and contour curvature of the composite board detected in real time by the visual camera, thereby adjusting the posture of the edge banding nozzle, including: fine-tuning up and down along the Z direction to adjust the height distance between the nozzle and the surface of the board; lateral movement along the X and Y directions to adapt to changes in the width or edge curve of the composite board; when necessary, adjust the slight inclination angle of the nozzle to better fit the edge of the board; through the coordinated control of visual detection and pressure sensor feedback, the edge banding nozzle is always in close contact with the edge of the composite board to ensure continuous and uniform glue discharge, avoiding defects such as glue breakage and glue accumulation.

[0049] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
