Description

Technical Field

[0001] This invention relates to a decorative patch forming mechanism and method. Background Technology

[0002] like Figure 1 The image shown is a sample diagram of a cabinet door decorative component or cabinet door structure. Existing cabinets are designed with a "fake drawer" appearance to reduce costs, or decorative patches are set on the furniture cabinet doors to improve the surface decoration. The cabinet door decorative component includes an outer frame 101, which is formed by splicing four panels. The outer frame is rectangular or square, and the four panels have the same width. The beveled edges are glued together. The inner side of the outer frame has a cut and shaped stepped surface 102, which forms a rectangular stepped surface after splicing. The inner side of the outer frame has a diagonal brace 103. The diagonal brace 103 is fixed to the outer frame with nails during manual operation. Then, a decorative panel 104 is covered on the outer surface of the diagonal brace 103. The thickness of the outer perimeter of the decorative panel 104 is consistent with the height of the stepped surface 102 to the surface of the outer frame.

[0003] The molding process for the aforementioned decorative components is quite complex. Firstly, the outer frame requires cutting, gluing, joining, and drying of the panels, fixing the diagonal braces, applying secondary glue, and fixing the decorative panels. The entire process is almost entirely manual, resulting in high costs and low efficiency. Even our company's existing rectangular frame panel positioning and hot-pressing molding device requires prior manual alignment and cannot be integrated with other processes. Furthermore, the fixing of the diagonal braces and the gluing of the decorative panels 104 also require multiple steps, leading to low efficiency and issues such as diagonal brace angle misalignment, inaccurate glue alignment on the step surface 102, and glue overflow onto the outer frame 101 surface. Summary of the Invention

The bearing seat is fixed with a threaded connection seat. The threaded connection seat is connected to the conveyor platform via a pressure roller spring. The threaded connection seat and the conveyor platform are also provided with an adjusting bolt that limits the extension and retraction of the pressure roller spring.

[0013] Preferably, both sides of the conveying platform are equipped with limiting stops for blocking workpieces and pressing and positioning cylinders for pressing down and limiting the decorative frame, located behind the inclined support pressing mechanism and behind the suspension. The telescopic end of the pressing and positioning cylinder is fixed with a pressing plate. The limiting stops are fixed to a telescopic positioning cylinder. The telescopic positioning cylinders are fixed on both sides of the conveying platform. The conveying platform is fixed with guide plates for limiting the rectangular frame, located in front of each telescopic positioning cylinder. The guide plates are fixed to the support platform with bolts. The front end of the guide plates has a guide slope. The spacing between the guide plates matches the outer frame.

[0014] The present invention also includes a method for forming decorative patches, which utilizes the above-mentioned decorative patch forming mechanism, and the specific steps are as follows:

[0015] (1) Two vertical pieces are pre-assembled, and then the frames are assembled by a pair of outer gluing cylinders moving towards each other. During operation, the outer corner clamping device and the inner corner clamping device are higher than the frame gluing platform. First, the inner gluing cylinder drives the inner frame to move to the outer frame, so that the gap width between the inner frame and the outer frame is consistent with the width of the plate or matches the width under the condition of meeting the accuracy requirements.

[0016] (2) Place a pair of boards to be spliced ​​between the two sets of corresponding inner baffles and the corresponding outer baffles. The conveyor roller drives the two boards on a feeding plate to move towards each other. Under the constraint of the inner baffles and the outer baffles, the boards moving towards each other eventually come together and are spliced. The outer baffle has a photoelectric sensor to sense the position of the board. When the board reaches the gluing area, the glue is sprayed on the gluing part of the board to be spliced. After the two boards located in one of the inner baffles and the outer baffles are glued and stable, the hot air blower is started. The corner of the feeding plate has a heat conduction port for the corresponding hot air blower. The hot air can quickly dry the glue at the frame bonding point, thereby improving the curing speed.

[0017] (3) The two outer corner clamping devices clamp the frame and move towards each other. The two inner gluing cylinders contract synchronously, so that the edges of the two pairs of assembled boards are glued together to form an outer frame. Then the inner baffle maintains pressure under the action of the inner gluing cylinder. Then the two outer corner clamping devices retract until the outer frame is freed from the support of the frame. The formed outer frame is located between the two inner baffles under the constraint of the inner baffle. The inner gluing cylinder contracts and the outer frame falls into the frame gluing platform below. Then it is output to the conveying platform by the conveyor chain on the frame gluing platform.

[0018] (4) The conveyor belt moves the outer frame to a pair of limit stops, the conveyor belt stops working, the lower pressure plate moves down under the drive of the lower positioning cylinder, presses the outer frame, the suction cup feeding mechanism sends the inclined brace to the conveyor platform and places the inclined brace in the designated position, then the extension end of the top pressure cylinder of the inclined brace pressing mechanism rises from the opening. In the initial state, the top of the arc-shaped top pressure plate should be located on one side of the inclined brace. As the top pressure cylinder gradually rises, the most protruding part of the arc-shaped top pressure plate can fully contact the inclined brace. Under the action of the spring, the middle part of the arc-shaped top pressure plate abuts against the side of the inclined brace, and then the suction cup feeding mechanism withdraws; there are mechanical arms on both sides of the conveyor platform, and nail guns are fixed on the mechanical arms. The nail guns are fixed by the mechanical arms or manually; the lower positioning cylinder moves up, the limit stops retract, and the conveyor belt outputs the workpiece that has completed the inclined brace fixing to the next limit stop;

[0019] (5) The limit stop bar located at the rear of the suspension extends to block the workpiece. After the workpiece is in place, the conveyor belt stops working. The downward positioning cylinder at the rear of the suspension presses down to limit the workpiece. The cover plate loading cylinder drives the cover plate suction cup to move down and uses the negative pressure pump to start adsorbing the board. After the glue rack is installed on the moving table, the moving table is driven to move laterally by the transverse mechanism so that each glue extrusion head is located at the corresponding position on the step surface. The glue lifting cylinder drives the glue rack to descend so that the glue extrusion head is close to the step surface. Then, the glue is applied to the step surface and the inclined support surface by extruding the glue. Then, the glue lifting cylinder drives the glue rack to rise. The moving table moves under the drive of the transverse mechanism so that the cover plate loading cylinder is above the step surface. Then, the cover plate loading cylinder drives the decorative panel to descend and fasten the decorative panel to the step surface to achieve the bonding of the decorative panel.

[0020] (6) The downward positioning cylinder on the rear side of the suspension moves upward and the limit stop bar retracts. The conveyor belt outputs through the cleaning roller. The cleaning roller can wipe the surface of the decorative panel to facilitate the removal of any possible glue leakage. After the completed decorative panels are stacked and naturally dried, the decorative patch is formed.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention utilizes the inner and outer baffle frames to clamp the sheet metal through the coordinated movement of the outer and inner gluing cylinders, which can satisfy the oblique splicing of the decorative frame and ultimately achieve the automated splicing of the overall frame.

[0023] In this embodiment of the invention, hot air bonding with hot air vents is used, which can improve bonding efficiency, meet the bonding requirements of decorative frames, and improve production efficiency. The upper part of the outer frame and the frame bonding platform has a vertically arranged glue spray pipe facing the board, which can spray liquid glue at the splicing parts of the board to facilitate automatic bonding of the splicing parts of the board.

[0024] The internal diagonal brace positioning and feeding mechanism of this invention utilizes a downward positioning cylinder and a suction cup feeding mechanism to achieve the limiting of the rectangular outer frame and the automatic feeding of the diagonal brace, which can improve production efficiency, reduce labor costs, and ensure the stability of the diagonal brace position. This invention uses the arc-shaped top pressure plate and spring to ensure the stability of the diagonal brace position and provide a guarantee for the fixation of the diagonal brace.

[0025] This invention utilizes the glue extrusion head on the glue lifting cylinder of the veneer bonding mechanism, in conjunction with the veneer loading cylinder to move the decorative panel, which can improve production efficiency, reduce glue overflow, lower labor costs, and improve product stability.

[0026] The cleaning roller structure used in the panel bonding mechanism in this embodiment of the invention can help to press the surface of the decorative panel while wiping the surface of the decorative panel. The use of vertical edges can prevent the glue extrusion head from overflowing onto the surface of the outer frame during the glue extrusion process. Attached Figure Description

[0047] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0048] See Figure 2-6A decorative patch forming mechanism includes a frame gluing platform 110 and a conveying platform 210 located behind the frame gluing platform. The frame gluing platform 110 has external corner clamping devices 120 on both sides and a support 1110 in the middle of the frame gluing platform 110. A pair of back-to-back symmetrically arranged internal corner clamping devices 130 are provided on the support 1110, corresponding to the external corner clamping devices. The external corner clamping device 120 includes a support for the board material. The feeding plate 1210 has a vertically right-angled outer frame 1220 fixed on its outer edge. The inner angle clamping device 130 includes an inner gluing cylinder 1310 fixed to the movable end of the lifting mechanism and a right-angled inner frame 1320 driven to move by the inner gluing cylinder 1310. The feeding plate 1210 is fixed to the telescopic end of an outer gluing cylinder 1230, which is fixedly connected to the frame gluing platform 110.

[0049] In this embodiment, to ultimately form a frame, the inner corner clamping devices are arranged in pairs and symmetrically facing away from each other, and the outer corner clamping devices are arranged in pairs corresponding to the inner corner clamping devices and facing each other. The outer corner clamping device 120 is used to limit the outer contour of the outer frame 101 after the board is introduced. The inner gluing cylinder 1310 drives the right-angled inner baffle 1320 to limit the inner contour of the board introduced on the loading plate 1210. During operation, the inner baffle 1320 and the outer baffle 1220 clamp the board under the coordinated opposing movements of the outer gluing cylinder 1230 and the inner gluing cylinder 1310.

[0050] In this embodiment, the aforementioned outer corner clamping device and inner corner clamping device cooperate to form an outer frame gluing structure for forming an outer frame. A conveyor platform 210 is also connected to the rear side of the frame gluing platform 110. The conveyor platform 210 has a conveyor belt 2110. An inner inclined brace positioning and feeding mechanism and a cover plate gluing mechanism are sequentially arranged above the conveyor belt along the material conveying direction.

[0051] In this embodiment, the inner baffle 1320 on the frame gluing platform 110 is right-angled and has inclined surfaces 1321 at both ends for introducing the plates. The inclined surfaces 1321 are used to guide the plates 100 so that each plate is gradually introduced between the inner baffle 1320 and the outer baffle 1220. The positioning is achieved through the action of the inner baffle 1320 and the outer baffle 1220, ensuring that two adjacent plates 1100 are set vertically.

[0052] The outer frame 101 is a structure of four plates spliced ​​diagonally. During operation, two of the plates are pre-assembled vertically, and then the frames are assembled by a pair of outer bonding cylinders 1230 moving in opposite directions.

[0053] During operation, the outer corner clamping device 120 and the inner corner clamping device 130 are higher than the frame gluing platform 110. First, the inner gluing cylinder 1310 drives the inner baffle 1320 to move towards the outer baffle 1220, so that the gap width between the inner baffle 1320 and the outer baffle 1220 is consistent with the width of the plate or, under the condition of meeting the accuracy requirements, consistent with the width.

[0054] Two boards 100 to be spliced ​​are placed between the two corresponding inner frames 1320 and the corresponding outer frames 1220. Two adjacent boards 100 that are perpendicularly spliced ​​are fed into the loading plate 1210, with the adhesive bevels of the two boards 100 facing each other. In actual design, adhesive can be pre-sprayed onto both ends of the boards manually before loading them. After the two boards located in one pair of inner frames 1320 and outer frames 1220 are glued and stabilized, the two outer corner clamping devices 120 clamp the frames and move them towards each other. The two inner adhesive cylinders 1310 simultaneously retract, causing the edges of the two pairs of spliced ​​boards to adhere to each other, forming the outer frame 101.

[0055] Subsequently, the inner retaining frame 1320 maintains pressure under the action of the inner gluing cylinder 1310. Then, the two outer corner clamping devices 120 retract until the outer frame 101 is released from the support of the frame. The outer frame 101 formed is located between the two inner retaining frames 1320 under the constraint of the inner retaining frame 1320. The inner gluing cylinder 1310 retracts, and the outer frame 101 falls into the frame gluing platform 110 below. It is then conveyed to the next process by the conveying mechanism on the frame gluing platform 110.

[0056] In one embodiment of the invention, to achieve automatic feeding, the feeding plate 1210 has a pair of conveyor rollers for guiding the material along the material entry direction. The upper surfaces of each conveyor roller group are flush, and each conveyor roller group consists of multiple arranged conveyor rollers 140. Each conveyor roller 140 is connected to the feeding plate via bearings and is hinged to the feeding plate 210 via bearings, protruding from the upper surface of the feeding plate 1210. The conveyor rollers are driven to rotate by a feeding motor. Each conveyor roller is coaxially fixed with a conveyor gear, and adjacent conveyor gears mesh with each other. One of the conveyor gears is driven to rotate by the feeding motor 1410. During installation, the interior or lower part of the feeding plate 1210 is hollow to accommodate the conveyor rollers.

[0057] During operation, the conveyor roller 140 drives two plates on a feeding plate 1210 to move towards each other. Under the constraint of the inner baffle 1320 and the outer baffle 1220, the plates moving towards each other eventually come together and are spliced. Then, the two outer corner clamping devices 120 clamp the frame and move towards each other. The two inner gluing cylinders 1310 contract synchronously (relieve pressure), so that the edges of the two pairs of spliced ​​plates are glued together to form the outer frame 101.

[0058] In one embodiment of the invention, the conveyor rollers 140 of the conveyor roller group are arranged obliquely towards the outer baffle 1220, thereby ensuring that the two plates in the same outer baffle 1220 are pushed against each other at opposite corners. Under the limitation of the gap between the inner baffle 1320 and the outer baffle 1220, the two plates will move towards the right angle of the outer baffle 1220, thereby satisfying the splicing.

[0059] To improve bonding efficiency, the frame bonding platform 110 is equipped with hot air vents 150 corresponding to the bonding points of the outer frame, specifically at the four corners of the outer frame bonding area. A hot air blower 1510, fixed to the frame bonding platform, is located below each hot air vent 150, with the blower's vents facing diagonally opposite the frame 101. The loading plate 1210 has heat-conducting openings 1221 at its corners for the hot air blower. The hot air allows for rapid drying of the adhesive at the frame bonding points, thereby increasing the curing speed.

[0060] Compared to the rectangular frames of traditional craft picture frames, decorative frames are generally smaller in size, with side lengths of 10-20cm and lower load-bearing requirements. In addition, decorative components need to be covered with a cover plate after the frame is finished, and the outer surface structure of the decorative blocks is enhanced by diagonal braces and nails. Therefore, a shorter gluing and drying time can be used.

[0061] The lower part of the inner frame 1320 has a groove 1322 that can cooperate with the stepped surface of the plate. The groove 1311 can better limit the plate at the upper part of the inner frame 1320 and prevent the edge of the plate from warping upward.

[0062] To ensure the stability of the feeding plate 1210 and the inner baffle 1320 during movement, the outer bonding cylinder 1230 is mounted on the frame. The feeding plate 1210 and the outer baffle 1220 have guides that cooperate with the frame. The inner baffle 1320 can have a sliding groove and track that cooperate with the bracket 1110 to improve accuracy and avoid deviation.

[0063] In one embodiment of the present invention, the upper part of the outer frame has a glue spraying pipe 160, the glue spraying pipe 160 has a nozzle 1610 that slopes downward toward the loading plate, and a pump body is provided on the glue spraying pipe. During operation, when the boards are driven to approach each other by the conveyor roller 140, the outer baffle frame 1220 has a photoelectric sensor to sense the position of the board entering. When the board reaches the gluing area, the glue spraying pipe sprays glue onto the gluing part of the boards to be joined.

[0064] The glue spray pipe 160 on the upper part of the outer frame is used to spray glue onto the two panels to be spliced ​​on the inner side of the outer frame, while the glue spraying platform above the frame is used to spray glue onto the edges of the two spliced ​​right-angled panels. In this embodiment, the nozzle 1610, which is angled downward toward the feeding plate, enables automatic glue spraying during the feeding process, avoiding excessive glue overflow caused by manual glue application.

[0065] To facilitate the movement of the outer frame 101, which is limited by the inner baffle 1320 after molding, onto the frame bonding platform 110, a conveyor chain 1120 is provided on the frame bonding platform 110. A pusher plate 1121 for pushing the outer frame is fixed on the conveyor chain. The pusher plate 1121 is used to ensure that the frame is conveyed to the next process area by the conveying mechanism on the frame bonding platform 110.

[0066] See Figure 8-11 The conveyor platform 210 is located on the rear side of the frame gluing platform and has an inner diagonal brace positioning and feeding mechanism. The inner diagonal brace positioning and feeding mechanism is used to place the diagonal brace 102 inside the outer frame, so that the diagonal brace 102 can be fixed to the outer frame manually or mechanically with a row of nails. The row of nails is located at the joint between the diagonal brace 102 and the outer frame.

[0067] The internal inclined brace positioning and feeding mechanism includes a suction cup feeding mechanism 220 located above the conveying platform 210 for clamping the inclined brace. The conveying platform is provided with a conveyor belt 2110 for inputting workpieces. Limiting bars 230 for blocking workpieces are provided on both sides of the conveying platform 210. Pressing and positioning cylinders 240 for pressing down and limiting the decorative frame are also provided on both sides of the conveying platform. The conveying platform has an opening 2120 in the middle, and an inclined brace pressing mechanism 250 is located below the opening.

[0068] In an embodiment of the invention, the inclined support pressing mechanism includes a pressing cylinder 2510, the telescopic end of which is vertically arranged and fixed with a horizontally arranged telescopic rod 2520, and the end of the telescopic rod is fixed with an arc-shaped pressing plate 2530.

[0069] In this embodiment, the telescopic rod 2520 includes a fixed rod 2521 fixed to the telescopic end of the top pressure cylinder 2510. A support rod 2522 is sleeved inside the fixed rod 2521. The support rod 2522 and the fixed rod 2521 are connected by a spring. The arc-shaped top pressure plate 2530 has a protrusion in the middle and bends towards the top pressure cylinder at the top.

[0070] The telescopic end of the pressing positioning cylinder 240 is fixed with a pressing plate 2410, and the limiting stop 230 is fixed to a telescopic positioning cylinder 2310. The telescopic positioning cylinder 2310 is fixed on both sides of the conveyor platform. The limiting stop 230 is arranged in parallel and perpendicular to the input direction of the conveyor belt.

[0071] During operation, the rectangular outer frame 101 enters the processing area via the conveyor belt 2110 of the conveyor platform 210. A pair of limit stops 230 extend under the drive of the telescopic positioning cylinder 2310 to prevent the outer frame 101 from moving forward. Then the conveyor belt stops working, and the lower pressure plate 2410 moves downward under the drive of the lower pressure positioning cylinder 240 to press the outer frame 101. The suction cup feeding mechanism 220 sends the inclined support to the conveyor platform and places the inclined support in the designated position. Then the telescopic end of the top pressure cylinder 2510 of the inclined support pressing mechanism 250 rises from the opening 2120. In the initial state, the top of the arc-shaped top pressure plate 2530 should be located on one side of the inclined support. As the top pressure cylinder 2510 gradually rises, the most protruding part of the arc-shaped top pressure plate 2530 can fully contact the inclined support 103. Under the action of the spring, the middle part of the arc-shaped top pressure plate 2530 abuts against the side of the inclined support 103. Then the suction cup feeding mechanism withdraws.

[0072] To improve stability, the fixed rod and the support rod have mutually cooperating guide structures, such as guide grooves and convex rails. In this embodiment, the conveyor belts 2110 are a pair and are respectively located on both sides of the opening on the conveying platform. The conveyor belts 2110 need to avoid the opening to prevent interference with the top pressure cylinder 2510.

[0073] In one embodiment of the invention, the suction cup feeding mechanism includes a slanted support process bracket 2210, a transverse slanted support feeding guide rail 2220 fixed on the slanted support process bracket 2210, a slanted support feeding slider 2230 slidably fitted on the slanted support feeding guide rail 2220, a feeding slider driving device on the slanted support process bracket for driving the slanted support feeding slider to move laterally along the slanted support feeding slider 2230, a slanted support suction lifting cylinder 2240 fixed on the slanted support feeding slider, and a suction cup 2250 fixed at the telescopic end of the lower part of the slanted support suction lifting cylinder 2240.

[0074] During operation, the inclined support suction lifting cylinder 2240, moved by the inclined support feeding slider 2230, switches between the material stacking area of ​​the inclined support workpiece and both sides of the conveying platform. When the inclined support suction lifting cylinder 2240 picks up material, it extends, and the suction cup 2250, connected to a negative pressure pump via a negative pressure pipeline, adsorbs the material. Multiple suction cups 2250 can be designed and evenly arranged along the inclined support direction. During material release, the inclined support feeding slider 2230 moves laterally under the drive of the feeding slider drive device. After the arc-shaped top pressure plate 2530 presses against the inclined support, the suction cup 2250 releases the negative pressure and is retracted and reset by the inclined support suction lifting cylinder 2240.

[0075] In this embodiment, the feeding slider driving device can be a cylinder, an electric cylinder, a hydraulic system, or a screw and nut system to drive the inclined support feeding slider 230 to move laterally. In this embodiment, the feeding slider driving device is a feeding cylinder 2231.

[0076] To ensure that the outer frame is in the preset position after entering, the conveying platform is fixed with a guide plate 260 for limiting the rectangular frame on the front side of the telescopic positioning cylinder. The guide plate is fixed to the support platform by bolts. The front end of the guide plate 260 has a guide slope 2610. The outer frame is gradually guided along the inner side of the guide plate under the conveyor belt 2110 until it is limited to the limiting stop bar 230.

[0077] The spacing between the guide plates matches the outer frame. The conveying platform has a limiting groove for fixing the guide plates, and the guide plates are fixed to the conveying platform by bolts passing through the limiting groove. The limiting groove structure allows for easy adjustment of the guide plate 260 position to accommodate outer frames 101 of different sizes.

[0078] The conveying platform is equipped with a photoelectric sensor to sense the contact between the edge of the outer frame and the limiting stop bar 230, thereby triggering the suction cup feeding mechanism to send the inclined support to the conveyor belt.

[0079] After the diagonal brace is loaded, a manual workstation can be set up on one side of the conveyor platform for manual nailing. Alternatively, an automatic nail gun can be used. As shown in the figure, when using an automatic nail gun to nail the edges of both ends of the diagonal brace to the outer frame, there are robotic arms 270 on both sides of the conveyor platform. Nail guns are fixed on the robotic arms 270, and the nail guns are used to nail the brace to the designated positions.

[0080] After the diagonal brace position is fixed, the limit stop 230 retracts, the lower pressure plate 2410 moves upward to reset under the drive of the lower positioning cylinder 240, and the conveyor belt 2110 runs, driving the workpiece that has completed the diagonal brace fixation to move to the next process area.

[0081] like Figure 12-16 As shown, similar to the positioning and limiting actions required by the internal inclined brace positioning and feeding mechanism, limiting stops 370 are provided on both sides of the conveyor platform within the process area to block the workpiece. Depressing positioning cylinders 350 are also provided on both sides of the conveyor platform 210 to press down and limit the decorative frame. A pressing plate 3510 is fixed to the telescopic end of the pressing positioning cylinder 350. The limiting stops 370 are fixed to a telescopic positioning cylinder 3710, which is fixed to both sides of the conveyor platform. The limiting stops 370 are arranged parallel to each other and perpendicular to the conveyor belt input direction.

[0082] During operation, the workpiece (i.e., the rectangular outer frame 101) enters the processing area via the conveyor belt 2110 of the conveyor platform 210. A pair of limit stops 370 extend under the drive of the telescopic positioning cylinder 3710 to prevent the outer frame 101 from moving forward. Afterward, the conveyor belt 2110 stops working, and the lower pressure plate 3510 moves downward under the drive of the lower pressure positioning cylinder 350 to press the outer frame 101. After the installation of the decorative panel 104 is completed, the limit stops 370 and the lower pressure plate 3510 reset, and the conveyor belt 2110 outputs the formed decorative patch.

[0083] In one embodiment of the invention, in order to ensure that the outer frame is in a preset position after entering, the conveying platform is fixed with a guide plate 360 ​​for limiting the rectangular frame on the front side of the telescopic positioning cylinder. The guide plate 360 ​​is fixed to the support platform by bolts. The front end of the guide plate 360 ​​has a guide slope 3610. The outer frame is gradually guided along the inner side of the guide plate under the conveyor belt 2110 until it is limited to the limiting stop bar 370.

[0084] The processing area has a decorative patch covering and gluing mechanism, which is located on a suspension 320 above the conveying platform. The suspension 320 has a moving platform 3210 driven by a lateral movement mechanism. A glue-applying lifting cylinder 3310 is fixed on the lower surface of the moving platform. A glue-applying frame 320 is fixed on the lower surface of the glue-applying lifting cylinder. A glue-applying extrusion head 330 is fixed on the glue-applying frame. A covering plate loading cylinder 3410 is also fixed on the lower surface of the moving platform. A covering plate suction cup 340 is fixed to the telescopic end of the covering plate loading cylinder. The covering plate suction cup is connected to a negative pressure pump via a pipeline.

[0085] The glue applicator 3320 includes crisscrossing rectangular support rods 3321. The glue extrusion heads 330 are evenly fixed on the support rods. The glue nozzle inlet pipe is connected to the glue storage tank. A metering pump is installed on the pipe to control the glue inlet of each glue extrusion head 330. Generally, the glue is in paste form.

[0086] The support rods 3321 can be fixedly connected to each other by bolts to facilitate adjustment according to the structure of decorative panels of different sizes and specifications. Of course, in actual design, the position of the adhesive extrusion head 330 can also be adjusted so that the adhesive extrusion head 330 corresponds to the stepped surface 102 of the outer frame.

[0087] The aforementioned cover plate suction cups 340 are multiple and arranged at the same height, and their lifting and lowering are uniformly controlled by the cover plate loading cylinder 3410.

[0088] During operation, the cover plate loading cylinder 3410 drives the cover plate suction cup 340 to move downwards, and the negative pressure pump starts to adsorb the board. After the glue application frame 3320 is installed on the moving table 3210, the moving table 3210 is driven to move laterally by the transverse mechanism, so that each glue extrusion head 330 is located at the corresponding position on the step surface 3102. The glue application lifting cylinder 3310 drives the glue application frame 3320 to descend, so that the glue extrusion head 330 approaches the surface of the step surface 3102. Then, the glue is applied to the step surface and the inclined support surface by extruding the glue. Then, the glue application lifting cylinder 3310 drives the glue application frame 3320 to rise. The moving table 3210 moves under the drive of the transverse mechanism, so that the cover plate loading cylinder 3410 is located above the step surface. Then, the cover plate loading cylinder 3410 drives the decorative panel 104 to descend and press the decorative panel onto the surface of the step surface, so as to achieve the bonding of the decorative panel 104.

[0089] The lateral movement mechanism is a suspension cylinder 3211 fixed on the suspension. The moving platform and the suspension have mutually cooperating guide rails and guide grooves. The telescopic end of the suspension cylinder is fixedly connected to the moving platform to drive lateral movement along the guide rail direction of the suspension.

[0090] In one embodiment of the invention, a vertical edge 3330 is fixed to the lower periphery of the support rod to prevent adhesive overflow. The upper end of the vertical edge 3330 is connected to the lower part of the support rod by a bolt 3331, and the support rod has an oblong hole for a limiting bolt. The oblong hole allows for easy adjustment of the position of the vertical edge. The vertical edge 3330 is used to align with the edge of the stepped surface 104 to prevent adhesive from leaking out of the outer side of the stepped surface.

[0091] A pressure sensor is fixed on the vertical edge 3330, which senses and determines the position of the adhesive application lifting cylinder 3310. When the vertical edge 3330 contacts the workpiece, it triggers the adhesive application lifting cylinder 3310 to stop moving, and the metering pump pumps the adhesive.

[0092] The output end of the conveyor belt 2110 is also fixed with a cleaning roller 380 located on the upper part of the conveyor platform. The cleaning roller 380 is driven to rotate by a cleaning motor 3820, and both ends of the cleaning roller are hinged to the conveyor platform via bearing seats 3801. The cleaning roller 380 can be used to press the glued decorative cover plate 104 and wipe the surface to facilitate the removal of any glue leakage. The surface of the cleaning roller 380 is covered with a towel cover 3810, which can be replaced periodically as needed.

[0093] In one embodiment of the invention, the bearing housing 3801 is fixed with a threaded connecting seat 3802. The threaded connecting seat is connected to the conveying platform 210 via a pressure roller spring 3803. Each bearing housing 3801 is provided with a pair of threaded connecting seats 3802. The threaded connecting seat and the conveying platform also have adjusting bolts 3804 for adjusting the extension and retraction of the pressure roller spring 3803. The lower end of the adjusting bolt 3804 is threadedly connected to the conveying platform. By adjusting the relative height between the adjusting bolt 3804 and the conveying platform 210, the pressure roller spring 3803 is limited, thereby adjusting the height of the bearing housing 3801 and the cleaning roller 380 to accommodate decorative patches of different thicknesses.

[0094] In the above embodiment, the conveyor belt in the middle of the conveying platform is a conventional conveyor belt, and the inner end of the guide plate 360 ​​extends into the upper part of the conveyor belt 2110 without contacting the middle conveyor belt 2110, thus playing a guiding role.

[0095] The present invention also includes a method for forming decorative patches, which utilizes the above-mentioned decorative patch forming mechanism, and the specific steps are as follows:

[0096] (1) Two vertical pieces are pre-assembled, and then the frames are assembled by a pair of outer gluing cylinders moving towards each other. During operation, the outer corner clamping device and the inner corner clamping device are higher than the frame gluing platform. First, the inner gluing cylinder drives the inner frame to move to the outer frame, so that the gap width between the inner frame and the outer frame is consistent with the width of the plate or matches the width under the condition of meeting the accuracy requirements.

[0097] (2) Place a pair of boards to be spliced ​​between the two sets of corresponding inner baffles and the corresponding outer baffles. The conveyor roller drives the two boards on a feeding plate to move towards each other. Under the constraint of the inner baffles and the outer baffles, the boards moving towards each other eventually come together and are spliced. The outer baffle has a photoelectric sensor to sense the position of the board. When the board reaches the gluing area, the glue is sprayed on the gluing part of the board to be spliced. After the two boards located in one of the inner baffles and the outer baffles are glued and stable, the hot air blower is started. The corner of the feeding plate has a heat conduction port for the corresponding hot air blower. The hot air can quickly dry the glue at the frame bonding point, thereby improving the curing speed.

[0098] (3) The two outer corner clamping devices clamp the frame and move towards each other. The two inner gluing cylinders contract synchronously, so that the edges of the two pairs of assembled boards are glued together to form an outer frame. Then the inner baffle maintains pressure under the action of the inner gluing cylinder. Then the two outer corner clamping devices retract until the outer frame is freed from the support of the frame. The formed outer frame is located between the two inner baffles under the constraint of the inner baffle. The inner gluing cylinder contracts and the outer frame falls into the frame gluing platform below. Then it is output to the conveying platform by the conveyor chain on the frame gluing platform.

[0099] (4) The conveyor belt moves the outer frame to a pair of limit stops, the conveyor belt stops working, the lower pressure plate moves down under the drive of the lower positioning cylinder, presses the outer frame, the suction cup feeding mechanism sends the inclined brace to the conveyor platform and places the inclined brace in the designated position, then the extension end of the top pressure cylinder of the inclined brace pressing mechanism rises from the opening. In the initial state, the top of the arc-shaped top pressure plate should be located on one side of the inclined brace. As the top pressure cylinder gradually rises, the most protruding part of the arc-shaped top pressure plate can fully contact the inclined brace. Under the action of the spring, the middle part of the arc-shaped top pressure plate abuts against the side of the inclined brace, and then the suction cup feeding mechanism withdraws; there are mechanical arms on both sides of the conveyor platform, and nail guns are fixed on the mechanical arms. The nail guns are fixed by the mechanical arms or manually; the lower positioning cylinder moves up, the limit stops retract, and the conveyor belt outputs the workpiece that has completed the inclined brace fixing to the next limit stop;

[0100] (5) The limit stop bar located at the rear of the suspension extends to block the workpiece. After the workpiece is in place, the conveyor belt stops working. The downward positioning cylinder at the rear of the suspension presses down to limit the workpiece. The cover plate loading cylinder drives the cover plate suction cup to move down and uses the negative pressure pump to start adsorbing the board. After the glue rack is installed on the moving table, the moving table is driven to move laterally by the transverse mechanism so that each glue extrusion head is located at the corresponding position on the step surface. The glue lifting cylinder drives the glue rack to descend so that the glue extrusion head is close to the step surface. Then, the glue is applied to the step surface and the inclined support surface by extruding the glue. Then, the glue lifting cylinder drives the glue rack to rise. The moving table moves under the drive of the transverse mechanism so that the cover plate loading cylinder is above the step surface. Then, the cover plate loading cylinder drives the decorative panel to descend and fasten the decorative panel to the step surface to achieve the bonding of the decorative panel.

[0101] (6) The downward positioning cylinder on the rear side of the suspension moves upward and the limit stop bar retracts. The conveyor belt outputs through the cleaning roller. The cleaning roller can wipe the surface of the decorative panel to facilitate the removal of any possible glue leakage. After the completed decorative panels are stacked and naturally dried, the decorative patch is formed.

[0102] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
