Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to an automated adhesive processing equipment for sheet metal and accessories, specifically a sheet metal processing equipment with adhesive accessories. Background Technology

[0002] Currently, the bonding and installation of boards and accessories mostly adopts the traditional process of "manual material loading, manual glue application, manual accessory positioning, and manual compaction," which has the following core problems:

[0003] 1. The manual operation process is loosely connected, and each batch takes a long time to process, making it difficult to meet the needs of industrialized mass production.

[0004] 2. Manual application of glue is prone to uneven glue thickness, missed areas, or accumulation, resulting in insufficient adhesion strength of accessories or glue overflow that contaminates the workpiece.

[0005] 3. Relying on manual visual positioning of accessories is prone to errors due to operational mistakes, which can cause the accessories to shift in position and require rework during subsequent assembly, increasing the scrap rate.

[0006] 4. Some boards (such as wood boards and acrylic boards) are easily scratched. During manual handling or compaction, improper force control can easily cause damage to the surface of the workpiece.

[0007] 5. The lack of coordinated control between processing stages makes continuous production impossible, resulting in a high proportion of labor costs.

[0008] Existing automated equipment only mechanizes a single step (such as automatic glue application), failing to form a complete "feeding-processing-collection" closed loop. Manual intervention is still required, which cannot fundamentally solve the aforementioned problems. Therefore, there is an urgent need for an integrated, highly automated, and precisely positioned sheet metal adhesive processing equipment to meet the dual demands of industrial production for efficiency and quality. Utility Model Content

[0009] This utility model aims to solve the problems existing in the prior art by providing a sheet metal processing equipment with adhesive attachments. This solves the problems of high reliance on manual labor, low precision, and poor efficiency in the current sheet metal and attachment adhesive processing, and meets the needs of fully unmanned operation, improved processing precision and production efficiency, and reduced workpiece damage rate.

[0010] The technical solution adopted by this utility model to solve its technical problem is as follows: This sheet metal processing equipment with adhesive attachments includes a conveyor belt, a first robotic arm at the side of the conveyor belt for moving the sheet metal from the outside onto the conveyor belt, an adhesive applicator on the conveyor belt for applying adhesive to the sheet metal, a calibration block located behind the adhesive applicator along the conveying direction for aligning the sheet metal, a second robotic arm at the side of the conveyor belt for gripping the attachment from the outside and placing it on the adhesive-coated sheet metal, and a top pressure plate on the conveyor belt for pressing and bonding the attachment to the sheet metal. With this configuration, through the coordinated operation of the conveyor belt, the first robotic arm, the adhesive applicator, the calibration block, the second robotic arm, and the top pressure plate, a fully automated processing system is constructed from sheet metal loading to attachment bonding and forming, achieving a comprehensive effect of improved processing efficiency, guaranteed precision, and stable quality. The conveyor belt, as the core transport carrier, provides a continuous and uniform movement path for the sheet metal, connecting all processing stages. The first robotic arm precisely transfers the external sheet metal to the preset position on the conveyor belt, avoiding deviations and damage caused by manual loading, and establishing a unified initial benchmark for subsequent processes. As the conveyor belt transports the sheet metal, the gluing device simultaneously and evenly applies glue to the specific areas on the sheet metal where attachments need to be bonded, solving the problems of uneven glue thickness and glue overflow caused by manual gluing, and ensuring that the amount of glue used is appropriate for the bonding requirements. Subsequently, the calibration block straightens and adjusts the sheet metal that may have shifted during transport, correcting lateral deviations or angular tilts, ensuring that the gluing area can accurately align with the subsequent attachment assembly position. When the sheet metal reaches the designated assembly station, the second robotic arm simultaneously picks up the attachment from the outside and precisely places it in the gluing area, eliminating the need for manual alignment and avoiding assembly misalignment caused by visual errors and hand tremors. Finally, the top pressure plate applies uniform pressure to the attachment, promoting full adhesion between the attachment and the gluing area of ​​the sheet metal, reducing gaps and strengthening the adhesion, preventing the attachment from falling off during subsequent use. The entire structural system eliminates the need for manual intervention in key processes such as handling, gluing, and assembly. This reduces manual labor and operational errors, while the seamless connection of each component ensures uninterrupted processing. It also guarantees full control over the entire process, from the accuracy of sheet material feeding, the uniformity of gluing, the position of accessory assembly, to the final bonding quality. Ultimately, this results in efficient, precise, and stable accessory bonding and processing, meeting the consistency and reliability requirements of mass production.

[0011] As a further improvement of this utility model, the gluing device includes a rotating roller with a roller-like structure. The rotating roller is coated with glue and comes into contact with the board as it passes by, forming a gluing structure for applying glue to the board. The gluing device is improved and optimized through the rotating roller with a roller-like structure. After the rotating roller is pre-coated with glue, it can form a stable gluing structure by contacting the surface of the board with the roller surface when the board is conveyed by the conveyor belt. This contact method can rely on the roller-like characteristics of the rotating roller to form a uniform and continuous glue layer in the area of ​​the board where the attachment needs to be bonded. This avoids the problems of glue layer breakage and uneven thickness that are easy to occur with manual gluing or non-roller gluing. Furthermore, by matching the rhythm of the rotating roller with the conveyor belt, it can ensure that the glue application speed is synchronized with the board movement speed, preventing missed coating or glue overflow caused by coating lag or advance.

[0012] As a further improvement of this utility model, the calibration block has an L-shaped right-angle structure, forming a straightening structure that uses the end wall of the calibration block to limit and push the plate through the predetermined position in a predetermined posture. In the overall processing system of the plate processing equipment with adhesive attachments, the straightening structure formed by the L-shaped right-angle calibration block, as a key transition link connecting the gluing device and the second robot, can be precisely adapted to the continuous conveying rhythm of the conveyor belt, realizing the orientation correction and posture regularization of the plate after gluing. When the plate after the glue has been applied by the gluing device is conveyed to the attachment assembly station by the conveyor belt, even if there are problems such as lateral displacement or angular tilt due to slight deviation in the initial feeding or slight shaking during the conveying process, the L-shaped right-angle end wall of the calibration block can apply a stable pushing force to the edge of the plate through the limiting effect, forcing the plate to gradually adjust its posture during continuous conveying, and finally pass through the predetermined area in a predetermined posture consistent with the conveyor belt conveying direction and with the gluing area precisely aligned with the subsequent placement position of the second robot attachment. This uprighting structure requires no additional power drive; relying solely on its own structure and the conveyor belt's collaborative transport, it ensures the uniformity and stability of the board material entering the accessory assembly stage. This provides a reliable positional reference for the second robotic arm to accurately grasp the accessories and place them in the adhesive application area of ​​the board material, thereby avoiding misalignment of accessories due to board posture deviations. It also ensures the bonding accuracy between the accessories and the board material during subsequent top pressure plate compaction and bonding. Ultimately, together with other structures in the equipment, it maintains the processing accuracy and stability of the entire process from board material feeding and adhesive application to accessory assembly and compaction, improving the consistency of overall product bonding quality.

[0013] As a further improvement of this utility model, a sensor is installed on the conveyor belt located between the gluing device and the calibration block to sense the movement of the board material from above. After the board material has been coated with adhesive in the bonding area by the gluing device, as it moves towards the calibration block along the conveyor belt, the sensor can sense the board material's movement in real time, accurately capturing the board's position signal—confirming that the board material has successfully completed gluing and entered the preset area before calibration, and providing an implicit trigger for the calibration block's straightening action to confirm "board material in place." This sensor eliminates the need for manual intervention to determine the board material's position, avoiding the problems of the calibration block "waiting in vain" or "board passing by without calibration" caused by delays or misjudgments due to manual observation. It ensures that each coated board material is accurately detected before reaching the calibration block, thereby ensuring that the calibration block can promptly apply a straightening force to any potentially misaligned board material through its L-shaped right-angle end wall, allowing the board material to enter subsequent processes in a neat posture. Meanwhile, the sensor's top sensing method can adapt to boards of different thicknesses and widths without affecting the normal conveyor belt transport or causing contact damage to the board surface. While maintaining the surface integrity of the board after gluing, it enhances the automation connection accuracy of the gluing and calibration process, providing a pre-position guarantee for the subsequent precise assembly of accessories by the second robotic arm and the effective compaction and adhesion of the top pressure plate. Ultimately, together with other structures of the equipment, it maintains the stability of the entire process from board feeding to finished product adhesion, improving the consistency and efficiency of the overall processing.

[0014] As a further improvement of this utility model, a board storage platform for storing boards is provided at the starting end of the conveyor belt, and an accessory storage platform for storing accessories is provided on the side of the conveyor belt near the second robot arm. The board storage platform at the starting end of the conveyor belt and the accessory storage platform near the second robot arm together constitute the material supply support structure of the equipment, providing material support for the continuous and efficient operation of the overall processing flow. Among them, the board storage platform at the starting end of the conveyor belt can centrally store the boards to be processed, so that the first robot arm does not need to frequently transfer boards from other external areas. It can simply grab the boards at the storage platform and transfer them to the starting end of the conveyor belt. This shortens the material acquisition distance for the first robot arm, reduces the time spent by the robot arm traveling back and forth, ensures the matching of the feeding rhythm with the conveyor belt conveying and subsequent gluing process, and avoids the tedious operation of manually carrying boards to the robot arm's working range. It also prevents the boards from being bumped and damaged during manual handling, ensuring the stability and integrity of the supply of boards to be processed. The accessory storage platform located on the side of the conveyor belt, near the second robotic arm, centralizes the accessories to be assembled within the second robotic arm's working range. This allows the second robotic arm to quickly grab the accessories without long-distance movement upon receiving an assembly command, precisely placing them in the glued area of ​​the sheet metal after gluing and calibration. This avoids delays in the second robotic arm's material retrieval due to accessories being stored too far away, thus ensuring synchronization with the sheet metal conveying rhythm and guaranteeing a smooth connection between the accessory assembly stage and the preceding glued and calibrated processes. These two storage platforms work in synergy with the first and second robotic arms, the conveyor belt, and subsequent processing structures to ensure a centralized and convenient supply of sheet metal and accessories from the material source. This reduces manual intervention in material handling, lowering labor costs and the risk of material loss. Furthermore, by shortening the robotic arm's material retrieval path and ensuring a continuous material supply, it maintains a seamless operation throughout the entire process from sheet metal loading, glued application, and calibration to accessory assembly and compaction. This prevents a decrease in processing efficiency due to interrupted material supply or excessively long retrieval times, ultimately improving the overall stability and efficiency of the processing in conjunction with other components of the equipment.

[0015] As a further improvement of this utility model, the execution terminals of the first and second robotic arms are vacuum suction cup structures. With this configuration, the execution terminals of the first and second robotic arms adopt vacuum suction cup structures, which can be deeply adapted to the material transfer requirements, processing accuracy requirements, and material protection requirements of the equipment, forming an efficient and reliable material gripping-placement collaborative mechanism. For the first robotic arm, it needs to pick up boards from the board storage platform at the beginning of the conveyor belt and transfer them to the conveyor belt. The vacuum suction cup can stably pick up boards of different materials and thicknesses through negative pressure adsorption, avoiding edge damage or surface scratches that may be caused by traditional mechanical grippers. At the same time, it ensures that the board does not shift its position during the transfer process and is accurately placed in the preset loading position of the conveyor belt, providing a regular initial material state for subsequent gluing and calibration. For the second robotic arm, it needs to pick up accessories from the accessory storage platform on the side of the conveyor belt and place them on the glued board. The vacuum suction cup can flexibly adapt to the size and shape of the accessories for adsorption, avoiding hand contamination or position misjudgment when manually picking up accessories. When transferring to the board gluing area, it can rely on the stable adsorption force of the suction cup to ensure the positional accuracy of the accessories during placement, preventing the accessories from tilting or misaligning during placement. The vacuum suction cup structure of both types of robotic arms does not require additional complex positioning components. It can achieve non-destructive and precise transfer of materials simply by negative pressure adsorption. It not only connects the material flow between the plate storage platform, the accessory storage platform and the conveyor belt, but also provides a precise material basis for the subsequent posture correction of the calibration block and the compaction and adhesion of the top plate, thereby improving the quality consistency of the adhesion of the plate and the accessory.

[0016] As a further improvement of this utility model, the gluing device includes a drive roller that drives the rotating roller to rotate synchronously, with the drive roller in tangential contact with the rotating roller. This structure, where the drive roller and rotating roller are in tangential contact and rotate synchronously, is the core transmission support ensuring the uniformity and continuity of gluing on the board. It can precisely match the board conveying rhythm of the conveyor belt, forming a stable gluing operation mechanism. When the equipment starts, the drive roller provides power and transmits it directly and efficiently to the rotating roller through tangential contact, ensuring that their speeds are completely synchronized and avoiding fluctuations in the rotating roller's speed due to transmission slippage. As the conveyor belt carries the board through the gluing device at a uniform speed, the synchronously rotating roller can contact the board surface at a stable linear speed, uniformly and continuously applying glue to the pre-set adhesion area of ​​the board. This prevents problems such as excessively thick or thin glue application or glue breaks caused by sudden changes in the rotating roller's speed, and also matches the conveyor belt's conveying speed, achieving a continuous operation of "board movement - synchronous gluing," avoiding processing interruptions caused by the separation of the gluing and conveying stages. This transmission structure eliminates the need for complex auxiliary transmission components. Reliable power transmission can be achieved through a simple design based on tangential contact, reducing potential equipment failures. It provides a uniform and complete adhesive base for subsequent calibration block posture correction, attachment assembly of the second robotic arm, and compaction and adhesion of the top pressure plate. Furthermore, it works in conjunction with other structures of the equipment to maintain the stability of the entire process from plate feeding to attachment and molding, ensuring the consistency of the final product's adhesion quality.

[0017] As a further improvement of this utility model, a receiving platform for receiving sheet metal with attachments is placed at the tail end of the conveyor belt. The receiving platform at the tail end of the conveyor belt, together with the preceding processing structures, forms a complete closed-loop material flow, providing a stable receiving carrier for the processed sheet metal with attachments. After the sheet metal is compacted by the top pressure plate and the attachments are attached, it is continuously conveyed to the tail end of the conveyor belt, where the receiving platform can directly receive the finished sheet metal. This eliminates the need for manual waiting at the tail end of the conveyor belt, avoiding losses caused by untimely reactions during manual receiving and reducing manual intervention in the transfer of finished products, thus maintaining the automated continuity of the overall processing flow. Meanwhile, the receiving platform allows finished products to be stacked and stored in an orderly manner, avoiding damage to accessories and scratches on the surface of the boards caused by random stacking. It ensures standardized material management throughout the entire chain, from board feeding (based on the board storage platform), processing (gluing, calibration, assembly, and compaction) to finished product collection (based on the receiving platform). Together with the first robotic arm, the second robotic arm, and the conveyor belt, it ensures efficient flow of "raw materials-processing-finished products", further enhancing the orderliness and finished product protection during batch processing, and improving the overall stability and convenience of production.

[0018] The beneficial effects of this utility model are as follows: The structure of this utility model is reasonable and compact. It connects the first robotic arm, gluing device, L-shaped calibration block, sensor, second robotic arm, top pressure plate, sheet and accessory storage platform, and receiving platform via a conveyor belt, forming a collaborative working system. This system specifically addresses the problems of excessive manual intervention, low positioning accuracy, poor production efficiency, and easy damage to workpieces in existing sheet and accessory gluing processes. The equipment achieves full automation of the entire process from "sheet feeding - gluing - posture calibration - accessory assembly - compaction - receiving," eliminating the need for manual intervention in key stages such as handling, gluing, and positioning. This reduces labor costs and eliminates human error. The gluing device relies on the synchronous operation of the active roller and the rotating roller. The transmission system ensures uniform adhesive application, while the L-shaped calibration block, in conjunction with sensors, corrects the orientation of the sheet material, guaranteeing precise adhesion between accessories and the sheet material, significantly improving the consistency of batch product quality. Each stage is seamlessly connected via a uniform conveyor belt, and the material storage platform optimizes the robotic arm's material handling path, drastically reducing processing time and adapting to the needs of industrial mass production. The robotic arm's vacuum suction cups for picking and placing materials, the smooth conveyor belt transport, and the orderly receiving platform prevent scratching, damage, or dropping of sheet material and accessories throughout the entire process, reducing workpiece damage and scrap rates. Furthermore, the overall structure is compact and the transmission is simple, requiring no complex auxiliary components, resulting in low energy consumption, fewer malfunctions, and flexible adjustments based on sheet / accessory specifications, making it widely applicable in industrial applications.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] Referring to the accompanying drawings: The sheet metal processing equipment with adhesive attachments in this embodiment includes a conveyor belt 1, a first robotic arm 2 at the side end of the conveyor belt 1 for moving the sheet metal from the outside onto the conveyor belt 1, an adhesive applicator on the conveyor belt 1 for applying adhesive to the sheet metal, a calibration block 3 located behind the adhesive applicator along the conveying direction for aligning the position of the sheet metal, a second robotic arm 4 at the side end of the conveyor belt 1 for grabbing the attachments from the outside and placing them on the sheet metal with adhesive, and a top pressure plate 5 on the conveyor belt 1 for pressing and adhering the attachments to the sheet metal.

[0025] The gluing device includes a rotating roller 6 with a roller-like structure. The rotating roller 6 is coated with glue and comes into contact with the board as it passes by, forming a gluing structure for applying glue to the board.

[0026] The calibration block 3 is an L-shaped right-angle structure, forming a straightening structure in which the calibration block 3 uses the end wall limit to push the plate through the predetermined position in a predetermined posture.

[0027] A sensor 7 is provided on the conveyor belt 1 located between the glue applicator and the calibration block 3, which senses the movement of the sensing plate above.

[0028] At the starting end of the conveyor belt 1, there is a board storage platform 8 for storing boards, and at the side of the conveyor belt 1 near the second robot arm 4, there is an accessory storage platform 9 for storing accessories.

[0029] The execution terminals of the first robotic arm 2 and the second robotic arm 4 are vacuum suction cup structures.

[0030] The adhesive applicator includes an active roller 10 that drives the rotating roller 6 to rotate synchronously, and the active roller 10 is in tangential contact with the rotating roller 6.

[0031] Preferably, a receiving platform 11 for receiving belt accessory plates is placed at the tail end of the conveyor belt 1.

[0032] The operating procedure of the sheet metal processing equipment with adhesive attachments is as follows: First, the sheets to be processed are stacked on the sheet metal storage platform at the beginning of the conveyor belt. The attachments to be attached are placed on the attachment storage platform near the second robot arm on the side of the conveyor belt. The main control switch is turned on to put the conveyor belt, gluing device (including rotating roller and drive roller), sensors, etc., into standby mode. Each robot arm is reset and the top pressure plate is raised. Then, the first robot arm uses a vacuum suction cup to grab a single sheet metal from the sheet metal storage platform and places it stably on the conveyor belt. The conveyor belt starts and drives the sheet metal to be conveyed to the gluing device. When the sheet metal approaches the gluing device, the drive roller starts and drives the tangential rotating roller to rotate synchronously (the speed matches the conveyor belt). The rotating roller evenly applies a certain amount of adhesive to the area of ​​the sheet metal to be glued. After gluing, the sheet metal continues to be conveyed. After the sensor detects the sheet metal, a hidden calibration action is triggered. Upon entering the L-shaped calibration block area, if any deviation or tilt occurs due to overshoot, the right-angled end wall of the calibration block will straighten the material to the predetermined posture. After receiving the linkage signal, the second robotic arm uses a vacuum suction cup to grab the accessory from the accessory storage table. When the calibrated sheet arrives at the assembly station, the accessory is precisely placed in the adhesive application area of ​​the sheet to complete the initial bonding. Then, the "sheet + accessory" is conveyed to the bottom of the top pressure plate. The conveyor belt pauses briefly (or maintains a low speed), and the top pressure plate applies a preset pressure downward under the drive of the power component. After maintaining this pressure for 3-5 seconds, it rises and resets, and the conveyor belt resumes operation to transport the material to the end. Finally, the sheet with the accessory slides down to the receiving table via the guide structure. The staff retrieves the material periodically. The entire process of "loading - adhesive application - calibration - assembly - compaction - receiving" is automatically cyclical until the material in the sheet or accessory storage table is exhausted. After replenishing the material, the process can continue.
