Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, and in particular to an automatic dispensing and curing production line for composite sheets. Background Technology

[0002] In the production and processing of composite panels, such as wooden door frames, picture frames, and furniture frames, multiple pieces of glued panels are typically joined together to form a frame structure, which is then cured under pressure. With the development of automation technology, automated glue dispensing and curing production lines for composite panels have gradually become widespread.

[0003] Currently, the industry mostly uses natural air drying, traditional cold pressing, or ordinary hot pressing methods to cure frame structures. These methods generally have drawbacks such as long curing cycles and slow production cycles, which to some extent restricts overall production efficiency and makes it difficult to fully meet the demands of modern large-scale, fast-paced production.

[0004] To shorten curing time, some production lines have introduced rapid pressure curing equipment. However, existing pressure curing equipment still faces some technical bottlenecks affecting overall efficiency when handling frame structures. Firstly, traditional curing fixtures often employ simple unidirectional side extrusion, lacking effective support for the bottom edge of the frame and simultaneous flexible positioning of the inner and outer walls. During pressurization, slight misalignment or uneven stress may occur at the frame corners. To ensure bonding strength, a longer holding time is usually required to compensate for insufficient positioning accuracy. Secondly, during pressure curing, trace amounts of air or adhesive can easily accumulate at the joints of the frame corners, potentially affecting local curing quality. Some existing equipment attempts to create micropores on the surface of the pressure plate or curing components and use negative pressure suction to assist in venting. However, under actual operating conditions, adhesive easily enters the micropores with the airflow and solidifies, gradually clogging the suction channel. This not only weakens the effect of auxiliary venting but may also increase the frequency of equipment downtime for maintenance, thus affecting the continuous operation efficiency of the production line.

[0005] Therefore, there is a need in this field to develop relevant production lines in a targeted manner, so as to effectively shorten the curing cycle and improve overall production efficiency while ensuring curing quality. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an automatic dispensing and curing production line for composite panels, which solves the problems of long curing cycle and slow production cycle of existing panel splicing production lines.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an automatic dispensing and curing production line for composite panels, comprising: The conveying module includes a first conveyor belt distributed along a first direction and a second conveyor belt disposed at the end of the first conveyor belt; The dispensing module is mounted on the first conveyor belt via a gantry frame and is used to dispense adhesive onto the sheet material conveyed by the first conveyor belt.

[0010] In one embodiment, the corner curing assembly includes a sliding mechanism, a curing bracket, a corner electrode, and a pressure electrode. The sliding mechanism extends from the corner of the worktable towards the central support assembly. The sliding mechanism includes a telescopic motor and a transmission screw. The curing bracket is mounted on the transmission screw via a sliding base, and the sliding base is driven to connect with the transmission screw. The corner curing assembly achieves synchronous displacement through the synchronous operation of each telescopic motor. The curing bracket is connected to the movable end of the sliding mechanism. The corner electrode is located at the bottom of the curing bracket. The pressure electrode is located directly above the corner electrode via a lifting cylinder. An insulating buffer pad is provided between the pressure electrode and the curing bracket. An L-shaped abutment is provided on the outer edge of the corner electrode. The abutment is used to abut against the outer wall surface of the corner of the frame structure. During curing, the abutment block and the abutment are respectively abut against the inner wall surface and the outer wall surface of the frame structure.

[0011] In one embodiment, the corner electrode is provided with an array of suction through holes, and the bottom of the corner electrode is provided with a suction cavity that communicates with the suction pipeline, and the suction through holes are connected to the suction cavity.

[0012] In one embodiment, the suction line is connected to the backflush line via a switching valve, which is used to backflush and clean the suction through hole when the machine is stopped or the suction is blocked.

[0013] In one embodiment, buffer sliders are provided on both the abutment seat and the two walls of the frame structure. The buffer sliders are embedded in the middle of the contact wall of the abutment seat. A buffer airbag is provided on the side of the buffer slider away from the frame structure. The buffer airbag is connected to the air supply pipe.

[0014] In one embodiment, the buffer slider is provided with a flexible abutment layer, the material of which is either silicone or polyurethane.

[0015] In one embodiment, the output end of the lifting cylinder is provided with a mounting plate, a pressure electrode is provided at one end of the mounting plate, and a guide shaft is provided at the end of the mounting plate away from the pressure electrode. The guide shaft passes through the curing bracket and extends upward.

[0016] In one embodiment, the dispensing module includes a dispensing assembly, a blocking assembly, and a detection assembly; The dispensing assembly includes a gantry spanning the first conveyor belt, a lifting mechanism mounted on the gantry, and a dispensing head driven to move up and down by the lifting mechanism. The dispensing head is connected to the lifting mechanism via a displacement mechanism to move along the width direction of the first conveyor belt. The blocking component is located at the rear end of the dispensing component and includes a drive component and a blocking plate that is driven by the drive component to move up and down in the vertical direction, for blocking or releasing the sheet material on the first conveyor belt. The detection component includes a sensor located at the front end of the blocking component. The sensor is used to detect the position of the board material and control the actions of the blocking component and the dispensing component in conjunction with it.

[0017] The beneficial effects of this invention are as follows: 1. This invention provides an automated dispensing and curing production line for composite panels. Through a modular, serial layout of a first conveyor belt, a second conveyor belt, a combination table, and a high-frequency curing module, it achieves smooth material flow transitions and tight process connections. This reduces material handling and downtime between processes in traditional production models, enabling highly efficient collaboration throughout the entire process from veneer loading, automated dispensing, frame assembly to pressure curing. Combined with precise positioning and rapid pressurization mechanisms within the production line, it effectively reduces overall curing waiting time, shortens production cycle time, and improves the overall production efficiency and automation level of composite panels.

[0018] 2. The automatic dispensing and curing production line for combined panels provided by this invention employs the cooperation between the telescopic extension part and the abutment block in the central support component, and the design of the buffer slider and buffer airbag on the L-shaped abutment seat on the outer edge of the corner curing component. By enabling the abutment block and the L-shaped abutment seat to simultaneously abut against the inner and outer walls of the frame structure during curing, and by providing flexible buffering through the airbag and flexible abutment layer during the contact process, this improves the phenomenon that traditional unidirectional extrusion clamps are prone to causing slight misalignment or uneven force at the corners of the frame. This optimizes the positioning effect and clamping flexibility of the frame structure and improves the fit at the joints during pressure curing.

[0019] 3. The present invention provides an automatic dispensing and curing production line for combined boards, which adopts an array of suction through holes on the corner electrodes and a bottom suction chamber. Combined with the design of connecting the suction pipeline to the back-blowing air path through a switching valve, the airflow control mechanism of alternating negative pressure suction and positive pressure back-blowing is constructed. This improves the situation where trace amounts of gas and adhesive are easily trapped at the corner joints during pressure curing, reduces the risk of frequent shutdowns for cleaning caused by adhesive blockage of traditional negative pressure micropores, extends the maintenance cycle of the suction channel, and ensures the continuous operation efficiency of the production line.

[0020] 4. The automatic dispensing and curing production line for combined boards provided by the present invention uses an insulating buffer pad between the pressure electrode and the curing bracket, and a guide shaft on the mounting plate that passes through the curing bracket. By providing vertical guidance and insulation isolation during the pressing process of the pressure electrode, the mechanical jamming or electrical interference that is prone to occur during the lifting and lowering process of the traditional pressure mechanism is improved, the stability of the vertical pressing of the pressure electrode is improved, and the service life of the equipment is extended.

[0021] 5. The present invention provides an automatic dispensing and curing production line for composite panels. The production line layout of the conveying module, dispensing module, assembly table and curing module is particularly important. The coordinated cooperation of the dispensing component, blocking component and detection component in the dispensing module, through the detection of the panel position by the sensor and the linkage control of the lifting and lowering of the blocking plate and the dispensing action, realizes the automated continuous operation of the panel from conveying, dispensing to assembly and curing. It improves the problems of low efficiency and poor consistency of dispensing position in traditional manual or semi-automatic frame assembly methods, and improves the production cycle and assembly accuracy of the frame structure.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. The technical features designed in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] In the description of this invention, it should be noted that all terms used in this invention (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains, and should not be construed as limiting the invention; it should be further understood that the terms used in this invention should be understood to have the same meaning as those in the context of this specification and in the relevant field, and should not be understood in an idealized or overly formal sense, except as expressly defined in this invention.

[0027] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0028] Please refer to Figures 1 to 7 An automated dispensing and curing production line for composite panels, comprising: The conveying module 1 includes a first conveyor belt 11 distributed along a first direction and a second conveyor belt 12 disposed at the end of the first conveyor belt 11; The dispensing module 2 is mounted on the first conveyor belt 11 via a gantry frame and is used to dispense adhesive onto the sheet material conveyed by the first conveyor belt 11. The assembly table 3 is located at the end of the second conveyor belt 12 and is used to assemble the glued sheets to form a frame structure. The high-frequency curing module 4, located at the rear end of the assembly table 3, includes a worktable 41, multiple sets of corner curing components 42 arranged around the worktable 41, and a central support component 43 located at the center of the worktable 41. Each set of corner curing components 42 includes upper and lower corresponding pressure electrodes 425 and separate corner electrodes 423. The pressure electrodes 425 and corner electrodes 423 cooperate to form a high-frequency electric field. The central support component 43 is used to support and position the frame structure to be cured. Specifically, the operator assembles the glued boards at the second conveyor belt 12 and the assembly table 3, and then places them on the central support component 43. The control module is electrically connected to the delivery module 1, the dispensing module 2, and the high-frequency curing module 4.

[0029] Specifically, the second conveyor belt 12 can be distributed along a second direction or along a first direction, with the second direction perpendicular to the first direction. More conveyor belts can also be connected to form a conveyor belt group. Those skilled in the art can make adjustments according to the actual situation without making specific limitations.

[0030] Before curing, the frame structure needs to be supported and positioned. Different frame structures have different dimensions, and space needs to be reserved for the corner curing components 42 to allow for movement. Therefore, in this embodiment, the central support component 43 includes a central lifting plate 431 located at the center of the workbench 41, with a lifting drive component 432 connected to the bottom of the central lifting plate 431. Several telescopic extensions 433 extend radially from the central lifting plate 431. These telescopic extensions 433 are generally cross-shaped or X-shaped, and their upper surfaces form a support surface for receiving the bottom edge of the frame structure. This design allows the central support component 43 to flexibly adjust its lifting range according to the size of the frame structure. The radial extension of the telescopic extensions 433 adapts to different sizes of frame bottom edges, and with the cooperation of the lifting drive component 432, the frame structure can be smoothly lifted and transferred. Simultaneously, the cross-shaped or X-shaped layout helps avoid the movement trajectory of the surrounding corner curing components 42, reducing the risk of mechanical interference and providing a more stable and compatible bottom support and positioning foundation for the frame structure.

[0031] During pressure curing, the frame structure needs to maintain accurate geometry to prevent misalignment at corner joints, and the internal support range needs to be adjusted for different frame sizes. Therefore, in this embodiment, an abutment block 4331 is provided on the supporting surface. The abutment block 4331 is used to abut against the inner wall of the frame structure, and the surface of the abutment block 4331 is provided with a wear-resistant insulating layer. The telescopic extension 433 is located between adjacent corner curing components 42, and a telescopic drive component 434 is embedded in the central lifting plate 431. The movable end of the telescopic drive component 434 is connected to the telescopic extension 433, and the telescopic drive component 434 drives the telescopic extension 433 to extend and retract synchronously. This arrangement allows the abutment block 4331 to cooperate with external components to form a two-way positioning constraint on the frame, which helps to alleviate the deformation or corner misalignment of the frame during pressure. At the same time, the wear-resistant insulating layer helps to extend the service life of the abutment block 4331 and can avoid electrical interference under high-frequency electric fields to a certain extent.

[0032] In this embodiment, the corner curing assembly 42 includes a sliding mechanism 421, a curing bracket 422, a corner electrode 423, and a pressure electrode 425. The sliding mechanism 421 extends from the corner of the worktable surface 41 toward the central support assembly 43. The sliding mechanism 421 includes a telescopic motor 4211 and a transmission screw 4212. The curing bracket 422 is mounted on the transmission screw 4212 via a sliding base 4213, and the sliding base 4213 is driven to connect with the transmission screw 4212. The corner curing assembly 42 achieves synchronous displacement through the synchronous operation of each telescopic motor 4211. The curing bracket 422 is connected to the movable end of the sliding mechanism 421. The corner electrode 423 is located at the bottom of the curing bracket 422. The pressure electrode 425 is located directly above the corner electrode 423 via a lifting cylinder 4251. An insulating buffer pad 4254 is provided between the pressure electrode 425 and the curing bracket 422. An L-shaped abutment is provided on the outer edge of the corner electrode 423, which abuts against the outer wall surface of the corner of the frame structure. During curing, the abutment block 4331 and the abutment abut against the inner and outer walls of the frame structure, respectively. Specifically, the sliding base 4213 is mounted on the transmission screw 4212 via a screw pair. This arrangement, through the screwed engagement between the transmission screw 4212 and the sliding base 4213, enables the curing bracket 422 to perform stable and high-precision linear displacement. Multiple sets of telescopic motors 4211 operate synchronously under the control of the control module, enabling each curing bracket 422 to move closer together synchronously, thus ensuring more uniform force distribution on the frame. The insulating buffer pad 4254 can isolate the upper and lower electrodes to a certain extent, reducing the risk of electrical interference and providing flexible buffering during the pressurization process, which helps to alleviate the rigid impact caused by slight differences in the thickness of the sheet material. The cooperation between the L-shaped abutment seat 424 and the internal abutment block 4331 forms a two-way clamping constraint, which helps to lock the corners of the frame structure more accurately, thereby reducing the phenomenon of misalignment or loosening of the corner joints during pressurization and providing structural protection for improving the curing quality.

[0033] During the pressure curing process, trace amounts of air or adhesive can easily accumulate at the corner joints of the frame structure, potentially forming bubbles or isolation layers in certain areas, thus affecting the curing quality. This requires improvement through an auxiliary venting structure. In this embodiment, the corner electrode 423 is provided with an array of suction through-holes 4231, and the bottom of the corner electrode 423 is provided with a suction cavity 4232 communicating with the suction pipe 4233. The suction through-holes 4231 and the suction cavity 4232 are connected. This arrangement allows the arrayed suction through-holes 4231 to expand the suction coverage area and, together with the suction cavity 4232 at the bottom, construct a negative pressure suction channel. This helps to directionally extract the trace amounts of gas and adhesive trapped at the joints, thereby improving the local curing quality at the corner joints to a certain extent and reducing poor bonding caused by gas retention.

[0034] Under actual negative pressure suction conditions, the suction through-hole 4231 is easily sucked in by overflowing adhesive or sawdust from processing, gradually becoming clogged, leading to suction failure and increasing the frequency of equipment downtime for maintenance. In this embodiment, the suction pipeline 4233 is connected to the backflushing air path via a switching valve, used to perform reverse purging cleaning of the suction through-hole 4231 when the machine is stopped or suction is blocked. This configuration allows the introduction of the switching valve to switch the air path between negative pressure suction and positive pressure backflushing. When needed, the backflushing air path applies reverse airflow to the suction through-hole 4231, which helps to remove residues in the channel, reduces the risk of micropore blockage failure, helps to extend the maintenance-free cycle of the electrode, and provides a certain guarantee for the continuous and stable operation of the suction-assisted exhaust function.

[0035] In actual processing, the frame structure may have slight dimensional tolerances, and a certain degree of flexible buffering is required during pressure curing to avoid rigid collisions or uneven local stress. In this embodiment, buffer sliders 4241 are provided on both the abutment seat and the two walls of the frame structure. The buffer sliders 4241 are embedded in the middle of the contact wall of the abutment seat, and a buffer airbag 4242 is provided on the side of the buffer slider 4241 away from the frame structure. The buffer airbag 4242 is connected to the air supply pipe 4243. This arrangement allows the buffer airbag 4242 to provide adjustable flexible support force, which helps to absorb the displacement caused by the dimensional tolerances of the frame and alleviate the stress concentration that may be caused by rigid abutment. At the same time, the buffer slider 4241 embedded in the middle helps to maintain the overall stability of the abutment surface, thereby improving the uniformity of lateral pressure and the reliability of clamping to a certain extent.

[0036] Furthermore, a pressure sensor is installed inside the buffer airbag 4242. The introduction of the pressure sensor allows the overall control module to acquire real-time pressure data within the airbag and adjust the air intake of the air supply pipe 4243 accordingly. This ensures that the clamping force is stably maintained within the set process range, preventing damage to the sheet surface or deformation of the frame due to excessive pressure, while also preventing insecure clamping due to insufficient pressure. This improves the parameter controllability and processing consistency of the pressure curing process.

[0037] Furthermore, the control module determines whether the airbags are in contact with the frame or whether the frame is deformed by comparing the pressure changes of different airbags 4242.

[0038] In this embodiment, the buffer slider 4241 is provided with a flexible abutment layer, which is made of either silicone or polyurethane. This design allows the flexible abutment layer made of silicone or polyurethane to provide a certain degree of elastic deformation when in contact with the frame structure, which helps to increase the contact area and alleviate local pressure, thereby reducing the risk of mechanical damage to the surface of the board to a certain extent. At the same time, silicone or polyurethane can increase the coefficient of friction of the contact surface, which helps to maintain the positional stability of the frame during the pressurization process.

[0039] When the pressure electrode 425 is pressed vertically downwards under the drive of the lifting cylinder 4251, it needs to ensure the straightness and stability of its movement to prevent uneven loading or jamming, and at the same time, it needs to maintain an appropriate relative position with the curing bracket 422. Therefore, in this embodiment, the output end of the lifting cylinder 4251 is provided with a mounting plate 4252, the pressure electrode 425 is set at one end of the mounting plate 4252, and the end of the mounting plate 4252 away from the pressure electrode 425 is provided with a guide shaft 4253, which passes through the curing bracket 422 and extends upwards. This arrangement ensures that the cooperation between the guide shaft 4253 and the curing bracket 422 provides reliable linear guidance for the lifting and lowering movement of the mounting plate 4252 and the pressure electrode 425, helping to alleviate the movement jamming phenomenon caused by unilateral force or uneven loading; at the same time, the mounting plate 4252 connects the pressure electrode 425 to the lifting cylinder 4251, which is conducive to transmitting stable downward pressure, thereby improving the stability and positioning accuracy of the vertical pressing of the pressure electrode 425 to a certain extent.

[0040] During the conveying process, the sheet material needs to be precisely positioned to ensure the accuracy of the dispensing location. Furthermore, the dispensing trajectory needs to be adjusted for sheets of different widths, and relative displacement of the sheet material during dispensing must be prevented. In this embodiment, the dispensing module 2 includes a dispensing component, a blocking component, and a detection component. The dispensing assembly includes a gantry spanning the first conveyor belt 11, a lifting mechanism mounted on the gantry, and a dispensing head driven to move by the lifting mechanism. The dispensing head is connected to the lifting mechanism via a displacement mechanism to move along the width direction of the first conveyor belt 11. The blocking component is located at the rear end of the dispensing component and includes a drive component and a blocking plate that is driven by the drive component to move up and down in the vertical direction, for blocking or releasing the sheet material on the first conveyor belt 11. The detection component includes a sensor positioned at the front end of the blocking component. This sensor detects the position of the sheet material and controls the actions of both the blocking and dispensing components. This arrangement enables automated linkage between detection, blocking, and dispensing actions, helping to ensure the sheet material remains in a fixed position during dispensing and improving the accuracy and consistency of the dispensing position. Simultaneously, the lateral adjustment of the displacement mechanism facilitates dispensing for sheets of varying widths, thus providing structural support for enhancing the overall automation and processing efficiency of the production line.

[0041] Specifically, the dispensing module 2 can adopt other dispensing structures as long as they can meet the needs of automatic dispensing. Those skilled in the art can make adjustments as needed, without making specific limitations.

[0042] In actual operation, the board is first smoothly conveyed by the first conveyor belt 11. When the sensor of the detection component detects that the board has reached the preset dispensing position, the control system links the blocking component, and the drive component drives the blocking plate to descend vertically to block and position the board. Subsequently, the lifting mechanism of the dispensing component drives the dispensing head to descend to the set height, and the displacement mechanism drives the dispensing head to perform precise dispensing along the width of the first conveyor belt 11. After the dispensing is completed, the blocking plate rises to release the board, and the board enters the second conveyor belt 12 with the conveyor belt and changes direction to be conveyed to the assembly table 3 area.

[0043] Next, the operator assembles the glued sheets into a frame structure at the assembly table 3 and places it directly onto the central support component 43 of the high-frequency curing module 4. At this time, the central lifting plate 431 rises under the drive of the lifting drive component 432, lifting the frame structure to the working height; simultaneously, the telescopic drive component 434 inside the central lifting plate 431 drives the cross-shaped or X-shaped telescopic extension 433 to extend synchronously, so that the abutment block 4331 on the supporting surface fits against the inner wall of the frame structure, providing initial internal support.

[0044] Subsequently, the corner curing assembly 42 begins to operate, and the telescopic motors 4211 of multiple sliding mechanisms 421 operate synchronously. Through the threaded engagement of the transmission screw 4212 and the sliding base 4213, the curing bracket 422 and the corner electrode 423 are driven to smoothly move towards the center along the corner of the worktable 41. When the L-shaped abutment seat 424 contacts the outer wall of the corner of the frame structure, the buffer airbag 4242 is compressed, and the pressure sensor inside it begins to collect pressure data in real time. The control system compares the pressure changes of different buffer airbags 4242 to determine whether the abutment seats on each side have made uniform contact with the frame, and whether there is any local deformation or improper placement of the frame. If an excessive pressure difference is detected, the system can adjust the air intake of the air supply pipe 4243 or fine-tune the sliding mechanism 421 to ensure that the frame is subjected to uniform force around its perimeter, avoiding rigid impact or local stress concentration.

[0045] After confirming the positioning and stress state are correct, the lifting cylinder 4251 drives the mounting plate 4252 and the pressure electrode 425 to press down vertically. The guide shaft 4253 passes through the curing bracket 422 to provide reliable linear guidance and prevent uneven loading or jamming. The pressure electrode 425 cooperates with the corner electrode 423 below to apply uniform curing pressure to the frame structure and form a high-frequency electric field. During this curing process, the suction pipe 4233 is connected to the negative pressure source through the switching valve. The array of suction through holes 4231 directionally extracts the trace amounts of gas and adhesive trapped at the corner joints to improve the local curing quality and reduce the generation of bubbles or isolation layers.

[0046] Finally, after the curing cycle ends, the pressure electrode 425 rises and resets, the corner curing component 42 retracts synchronously, the central support component 43 descends and retracts, and the operator or unloading mechanism removes the cured frame structure. Furthermore, when the equipment stops or the system detects abnormal suction resistance, the switching valve automatically switches to the backflush air path, introducing positive pressure gas into the suction chamber 4232 to backflush and clean the suction through-hole 4231, maintaining the suction channel's unobstructed flow and preparing for the next processing cycle.
