Description

Technical Field

[0001] The invention relates to the field of multilayer board production equipment, in particular to a feeding device for multilayer board processing and production. Background Art

[0002] In the field of sheet material processing and manufacturing, especially the production of multi-layer panels, single-layer panels often require surface repair, quantitative gluing, precise leveling, and alternating positioning and conveying with adhesive sheets to meet the requirements of subsequent hot pressing or lamination. To improve production efficiency and product quality, the industry is gradually transitioning from traditional manual processing to automated conveying and surface treatment devices. In particular, in the context of supporting intelligent heat treatment production lines, higher requirements are placed on the intelligence and integration of front-end loading and processing equipment.

[0003] As a key component of modern sheet metal hot pressing and laminating processing, the operating efficiency and processing quality of the intelligent heat treatment production line largely depend on the coordination and processing accuracy of the front-end loading device. If surface defects in the front-end processing are not repaired in time, the glue is unevenly applied, or there is a conveying positioning error, it will directly affect the temperature and pressure distribution and bonding quality during the heat treatment process, thereby causing quality problems such as hollowing, delamination, and warping in the multi-layer board after heat treatment, which seriously restricts the overall operating efficiency and product qualification rate of the intelligent production line.

[0004] Furthermore, while some devices have adhesive supply and preliminary filling functions, the filling process is often unable to automatically adjust the amount of glue output based on the depth or area of the defect, which can easily lead to insufficient filling or excessive glue overflow, affecting the flatness of the panel surface and the quality of the product appearance. Furthermore, after completing the conveying, docking, and positioning of the single panel and the bonding plate, existing equipment generally lacks an efficient automatic reset mechanism, requiring manual intervention to reset the limit structure, further limiting the equipment's intelligence level and stable operation capabilities.

[0005] Therefore, it is necessary to provide a multilayer board processing and loading device with a reasonable structure, automatic detection and filling, leveling and trimming, conveying and positioning, and automatic resetting functions. The device should be efficiently connected with the intelligent heat treatment production line to improve the intelligence and refinement of the front-end processing, thereby comprehensively solving the problems of inaccurate defect repair, unstable positioning and docking, and low degree of automation in the existing technology, and effectively improving the overall production process efficiency and finished product qualification rate of multilayer board products.

[0006] After searching, it was found that the prior art publication number is CN215453459U, which discloses a single-machine production equipment for fully automatic multi-layer board processing that is easy to feed, including a device body and a stacking mechanism. A pushing mechanism is installed on one side of the device body, and the stacking mechanism is arranged on one side of the pushing mechanism, and the pushing mechanism is flush with the horizontal line of the stacking mechanism. This scheme can drive the pressing plate to move up and down through the first cylinder, so that after the plates are stacked, downward pressure can be provided, so that the multi-layer plates can be pressed. At the same time, four first cylinders are arranged above the pressing plate, which can ensure high-strength pressure while making the force more uniform. Through the reset spring, the top column can be moved up and flush with the lower surface of the pressing plate when pressing down. After pressing, the top column automatically recovers and is ejected due to elasticity, thereby avoiding the plates from sticking to the pressing plate after pressing.

[0007] Therefore, based on the above search and combined with existing technologies, there is an existing stand-alone production equipment for fully automatic multi-layer board processing that is easy to feed. This device only realizes the pressing process after the multi-layer boards are stacked, and does not involve the automatic detection and filling function of panel surface defects. At the same time, although the device has a pressing action, it lacks automatic control in terms of stacking positioning and structural reset. Summary of the Invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. During use, the present invention provides a detection component, a filling component, and a smoothing component on the conveyor platform body, enabling automatic detection and high-precision filling of surface depressions during panel conveyance. The detection component contacts the top surface of the panel via a sensor block, accurately identifying the location and depth of the depression.

The brush in the smoothing component always maintains contact with the panel under the action of the fourth spring, evenly smoothing the glue dripping on the surface. This not only effectively fills the concave area, but also ensures that the panel surface is flat and free of glue bumps, improving the tightness and uniformity of the fit between it and the adhesive plate, thereby making it more suitable for the hot pressing or multi-layer composite process in the subsequent intelligent heat treatment production line, reducing defects such as hollowing and delamination caused by poor fitting, and improving the product qualification rate;

[0022] 3. During use, the present invention realizes efficient and stable positioning and stacking of panels and adhesive plates through the cooperation of the conveying support platform with the connecting rod, sliding block and clamping plate. After the positioning is completed, the conveying support platform links the ratchet disk and the fifth spring mechanism under the action of gravity to realize the automatic reset of the limiting structure, so that the sliding block automatically returns to its position, ensuring the continuous progress of the subsequent panel stacking process. The automatic reset structure effectively simplifies the manual intervention process, improves the automation level and operating efficiency of the equipment, and is particularly suitable for seamless docking with the intelligent heat treatment production line and continuous production requirements, and enhances the collaborative operation capability of the entire line.

A motor 13 is fixedly installed on the inner bottom surface of the conveyor frame 11 by bolts. The output shaft of the motor 13 is connected to the number of transmission rollers 12 through a transmission chain 14. Specifically, the model of the motor 13 is 1FL6044-1AF61-2LB1. The output shaft of the motor 13 is coaxially fixed with a transmission gear. The rotating shafts of the number of transmission rollers 12 pass through the side wall of the conveyor frame 11 and are coaxially fixed with driven gears. The transmission chain 14 is meshed and sleeved on the outer walls of the transmission gear and the number of driven gears. The transmission chain 14 remains taut.

Specifically, a plurality of mounting holes are opened on the top surface of the first mounting bracket 21 at equal intervals. A plurality of cylinders 22 are fixedly mounted in the mounting holes. A first piston rod 23 is slidably mounted on the inner wall of each cylinder 22. A sensing block 231 for detecting the depression of the panel surface is fixedly mounted on the bottom end of the first piston rod 23. Specifically, the bottom surface of the sensing block 231 is an arc surface, and the outer wall of the first piston rod 23 is sleeved with the first piston rod 23. A spring 24, the detection component 2 can realize automatic identification of defects on the surface of the panel before entering the intelligent heat treatment production line, so as to ensure the quality of the panel for subsequent processes. Specifically, the top of the first spring 24 abuts against the bottom surface of the piston of the first piston rod 23, and the bottom end of the first spring 24 abuts against the inner bottom surface of the cylinder 22. The first spring 24 has an upward force on the first piston rod 23. The tops of the several cylinders 22 are connected to an air supply pipe 25, and the air supply pipe 25 is connected to the inside of the several cylinders 22.

Specifically, the air pump 28 supplies air to several cylinders 22 through the air pipe 25, compressing the first spring 24 to move the first piston rod 23 downward in the cylinder 22, so that the sensing block 231 abuts against the top surface of the panel. The elastic coefficient of the first spring 24 is smaller than the elastic coefficient of the second spring 27. When the air pressure inside the pipeline reaches a certain threshold, the high-pressure gas pushes the first ball valve 26 to disengage it from the abutment ring, compressing the second spring 27. The high-pressure gas is discharged through the vent pipe 251, so that the pressure inside the air pipe 25 is constant.

[0049] Example 2: Please refer to Figures 3 to 10, a feeding device for multi-layer board processing and production, which is different from Example 1 in that the filling component 3 includes a second mounting frame 31, which is fixedly mounted on the inner wall of the conveying frame 11 by bolts, and a plurality of discharge cylinders 32 are fixedly mounted on the top surface of the second mounting frame 31 at equal intervals. Specifically, the distance between the discharge cylinder 32 and the cylinder 22 is less than or equal to 10 cm to ensure the accuracy of filling after detection. A plurality of mounting holes are equidistantly opened on the top surface of the second mounting frame 31, and a plurality of discharge cylinders 32 are fixedly mounted in the mounting holes.

Specifically, epoxy resin has excellent adhesion and has strong adhesion to materials such as metal, glass, ceramics, and concrete. At the same time, the epoxy resin has good volume stability and small shrinkage after curing. The storage cylinder 36 is connected to the delivery pipe 35. The filling component 3 can repair defects and quantitatively fill glue on the panels before entering the intelligent heat treatment production line, thereby improving the fit and hot pressing quality between the panels. Specifically, the epoxy resin inside the storage cylinder 36 is transported into the interior of several discharge cylinders 32 through the delivery pipe 35. A discharge pipe 321 is provided on the bottom surface of the discharge cylinder 32, and a storage pipe 322 is provided on the outer wall of the discharge pipe 321. The storage pipe 322 and the discharge pipe 32 1 is connected internally, the inner wall of the storage tube 322 is slidably connected to the second ball valve 33, the outer diameter of the second ball valve 33 is adapted to the inner diameter of the discharge tube 321, the outer wall of the second ball valve 33 is fixedly connected to the third spring 34, the outer wall of the second ball valve 33 is fixedly connected to the connecting rope 4, the end of the connecting rope 4 away from the second ball valve 33 passes through the storage tube 322 and the outer wall of the cylinder 22 and is fixedly connected to the top surface of the first piston rod 23, specifically, the end of the third spring 34 away from the second ball valve 33 is fixedly connected to the end of the inner wall of the storage tube 322, the third spring 34 releases the elastic force to push the second ball valve 33 into the discharge tube 321, so that the discharge tube 321 is closed, and the epoxy resin inside the discharge cylinder 32 cannot be discharged. When the sensing block 231 of the plug rod 23 detects the depression of the outer wall of the panel, the air pressure inside the cylinder 22 pushes the first piston rod 23 to move downward, and the first piston rod 23 pulls the second ball valve 33 through the connecting rope 4, so that the second ball valve 33 partially enters the storage tube 322, and a gap is generated between the second ball valve 33 and the inner wall of the discharge pipe 321. The epoxy resin inside the discharge cylinder 32 is discharged through the gap and falls on the panel surface. The larger the depression on the panel surface, the longer the gap between the second ball valve 33 and the inner wall of the discharge pipe 321 is generated, and the more epoxy resin flows out. The deeper the depression on the panel surface, the larger the gap between the second ball valve 33 and the inner wall of the discharge pipe 321, and the more epoxy resin flows out.

Specifically, the fourth spring 54 releases the elastic force, pushing the sliding rod 53 downward, so that the brush 531 abuts against the top surface of the panel, and the brush 531 smears the epoxy resin dripping on the surface of the panel, smoothes the epoxy resin, and completely fills the depression.

[0051] Example 3: Please refer to Figure 2 、 Figures 11 to 14 , a feeding device for multi-layer board processing and production, which is different from Example 1 in that telescopic cylinders 62 are installed at the four corners of the top surface of the base 61, and the bottom surface of the conveying support platform 63 is fixedly connected to the telescopic ends of the four telescopic cylinders 62. Specifically, the telescopic cylinders 62 have a limiting effect on the conveying support platform 63, so that the conveying support platform 63 can only move vertically up and down above the base 61.

[0052] See also Figures 11 to 14The adjustment assembly 7 includes a ratchet plate 71, which is rotatably connected to the center of the top surface of the base 61. Specifically, a bearing 72 is installed between the outer wall of the rotating shaft of the ratchet plate 71 and the inner wall of the rotating groove opened on the top surface of the base 61.

Specifically, an annular groove 711 is opened at the center of the top surface of the ratchet plate 71, and a convex ring is provided on the bottom surface of the rotating ring 73. The convex ring is slidably inserted in the annular groove 711. The annular groove 711 has a limiting effect on the convex ring. The top surface of the rotating ring 73 is coaxially fixed with a fifth spring. 74, the end of the fifth spring 74 away from the rotating ring 73 is fixedly connected to the center of the bottom surface of the conveying support platform 63, and a rotating column 75 is coaxially fixedly installed at the center of the top surface of the ratchet disk 71. An adjustment plate 751 is welded to the outer wall of the rotating column 75, and the adjustment plate 751 is inserted between the spring wires of the fifth spring 74. An extension rod 632 is welded and fixed to the bottom surface of the conveying support platform 63, and a push rod 76 is hinged at the end of the extension rod 632. A torsion spring is installed between the push rod 76 and the end of the extension rod 632. A ratchet block 761 is provided on the bottom surface of the end of the push rod 76 away from the extension rod 632, and the ratchet block 761 is engaged with the ratchet disk 71 Specifically, when the adhesive plate and the panel cross and fall on the top surface of the conveying support platform 63 in sequence, the conveying support platform 63 moves downward under the influence of gravity, and the fifth spring 74 is compressed by the connecting rod 65, which drives the sliding block 64 to move in the slide rail 631. The clamping plates 641 of the four sliding blocks 64 position the panel on the top surface of the conveying support platform 63 by moving toward each other. However, if the positioning of the second layer of panels is to be achieved, the four sliding blocks 64 need to be reset. When the conveying support platform 63 moves downward, the extension rod 632 drives the push rod 76 to move, and the push rod 76 drives the ratchet plate 71 to rotate through the ratchet block 761. At this time When the torsion spring is compressed, the ratchet disk 71 drives the rotating column 75 to rotate, and the adjustment plate 751 on the outer wall of the rotating column 75 rotates accordingly, releasing the part of the spring wire of the fifth spring 74 compressed by the adjustment plate 751, changing the length of the fifth spring 74, and offsetting the gravity of the panel through the elastic performance of the part of the spring wire released by the fifth spring 74, and the conveying support platform 63 moves upward to restore its initial height. The four sliding blocks 64 move to their initial positions respectively driven by the four connecting rods 65, and the torsion spring releases the elastic force, causing the ratchet block 761 of the push rod 76 to re-engage with the ratchet disk 71, making it convenient for the next panel positioning work.

[0053] The working principle of the present invention is as follows: when the device is in use, two conveyor bodies 1 are used to convey the panel and the adhesive plate with glue applied on the surface respectively. The conveyor body 1 used for conveying the panel is equipped with a detection component 2, a filling component 3 and a smoothing component 5 in sequence, which are used to realize the recognition, automatic filling and surface finishing of panel defects;

[0054] During the operation of the device, the panel is first placed on the conveyor frame 11. Under the drive of the motor 13, the transmission gear set on the output shaft of the motor 13 is meshed with the driven gears on the multiple transmission rollers 12 through the transmission chain 14, so that the transmission chain 14 drives the multiple transmission rollers 12 to rotate synchronously. Through the continuous rotation of multiple transmission rollers 12, the panel is stably conveyed;

[0055] The air pump 28 is started. When the panel moves to the position directly below the detection assembly 2, the air pump 28 supplies air to the cylinders 22 through the air pipe 25. Under the influence of the air pressure, the first piston rod 23 moves downward in the cylinder 22. The sensing block 231 at its bottom end presses down to the panel surface and contacts the top surface of the panel to detect whether there is a depression on the surface. If a depression is encountered, the first piston rod 23 continues to compress the first spring 24 and moves downward. When the air pressure exceeds a preset threshold, the first ball valve 26 is pushed out of contact with the abutment ring by the high-pressure gas, compressing the second spring 27 and causing some of the gas to be discharged through the bleed pipe 251, thereby maintaining a stable pressure in the entire system and avoiding false detection or damage to the cylinder 22.

[0056] When the first piston rod 23 moves downward, the top end of the first piston rod 23 pulls the second ball valve 33 connected to it through the connecting rope 4. The second ball valve 33 originally tightly seals the discharge pipe 321 under the action of the third spring 34. After the second ball valve 33 is pulled, part of the second ball valve 33 enters the storage pipe 322 and forms a gap with the inner wall of the discharge pipe 321, so that the epoxy resin in the discharge cylinder 32 is discharged smoothly. The larger the depression on the panel surface, the longer the gap between the second ball valve 33 and the inner wall of the discharge pipe 321 is generated, and the more epoxy resin flows out. The deeper the depression on the panel surface, the larger the gap between the second ball valve 33 and the inner wall of the discharge pipe 321 is generated, and the more epoxy resin flows out. Therefore, the glue output amount can be automatically adjusted to ensure that depressions of different degrees are effectively filled, thereby improving the quality of the board.

[0057] The panel is further conveyed to the smoothing assembly 5 area. The smoothing assembly 5 is provided with a plurality of sliding cylinders 52 and sliding rods 53. A brush 531 is installed at the bottom of the sliding rod 53. The sliding rod 53 is always kept in contact with the panel under the action of the fourth spring 54, so that the brush 531 runs closely against the panel surface. The epoxy resin dripping on the panel surface is evenly smoothed by the brush 531, and the depressions are completely filled, ensuring that the panel surface is flat and free of residual glue or protrusions, which is convenient for subsequent hot pressing or laminating operations.

[0058] After the panel and the adhesive sheet are respectively conveyed to the end where the two conveyor bodies 1 intersect, they are alternately stacked by the positioning adjustment mechanism 6. The conveyor support platform 63 is controlled by the telescopic cylinders 62 installed at the four corners of the base 61 to move up and down, allowing the conveyor support platform 63 to move only in the vertical direction. When a panel falls on the conveyor support platform 63, the conveyor support platform 63 moves downward due to gravity, and then the four sliding blocks 64 are driven by the connecting rod 65 to slide toward each other in the slide rail 631, and the panel is limited and positioned by the clamping plate 641;

[0059] In order to achieve the positioning of the second layer of panels, the sliding block 64 needs to be reset. During the downward movement of the conveying support platform 63, the extension rod 632 at the bottom drives the push rod 76 to press down. The bottom end of the push rod 76 is provided with a ratchet block 761 which engages with the ratchet plate 71. The extension rod 632 drives the push rod 76 to move. The push rod 76 drives the ratchet plate 71 to rotate through the ratchet block 761, and then the ratchet plate 71 drives the rotating column 75 and the adjusting plate 751 to rotate, and the adjusting plate 751 releases the compressed fifth spring. 74 spring wire, changes the length of the fifth spring 74, and the elastic performance of the part of the spring wire released by the fifth spring 74 offsets the gravity of the panel. The conveying support platform 63 moves up and resets under the action of the elastic force, and the sliding block 64 returns to the initial position through the drive of the connecting rod 65. At the same time, the torsion spring releases the elastic force to drive the push rod 76 to rotate, so that the ratchet block 761 and the ratchet disk 71 are re-engaged, thereby completing the automatic reset of the positioning module and preparing for the next round of loading and positioning operations; at this point, the work of this device is completed.
