Description

Technical Field

[0001] The invention relates to a robot automatic box opening and sealing mechanism, belonging to the technical field of packaging devices. Background Art

[0002] In the field of modern ceramic manufacturing, center-side basins, as a common daily ceramic utensil, have a variety of sizes and designs, providing great flexibility and convenience, and meeting the needs of use in different scenarios. However, center-side basins vary in size, and they need to be finely arranged in different sizes during firing to maximize the utilization of kiln space, ensure even heat distribution, and reduce deformation. This leads to the problem of random specifications and sizes of incoming materials on the center-side basin packing production line. The traditional method based on manual assembly is not only inefficient overall, but also has high labor costs. It requires stricter supervision and a higher level of coordination. Product quality is difficult to guarantee and can no longer meet the market demand for high turnover.

[0003] With the continuous development of artificial intelligence technology, intelligent assembly systems with industrial robots as the main body have helped to greatly improve production flexibility and shorten product processing cycles. At the same time, through the communication and interaction of management software systems such as manufacturing execution systems (MES) and enterprise resource planning systems (ERP), the entire process of product assembly and delivery can be automated. The rapid development of visual technology and intelligent sensors has enabled assembly production lines to have a higher level of intelligence. Advanced visual technology can not only monitor the production process in real time, but also perform quality inspection and anomaly detection to ensure the accuracy of each link. Intelligent sensors provide key feedback information by collecting data in real time, further enhancing the system's adaptive capabilities.

[0004] For example, an automatic carton opening and sealing machine disclosed in the application number: 201710572997.1 is provided with a carton opening station, a carton packing station and a carton sealing station in sequence on the conveyor line. The carton feeding mechanism can automatically deliver the carton plate to the carton opening station. At the carton opening station, the carton plate is opened into a carton by the carton opening mechanism. When the carton is moved from the carton opening station to the carton packing station, the bottom side panel of the carton is folded by the bottom carton sealing mechanism. At the carton packing station, the product cartoning operation is realized. When the carton is moved from the carton packing station to the carton sealing station, the top side panel of the carton is folded by the top carton sealing mechanism, thereby realizing automatic carton feeding, carton opening, carton packing and carton sealing operations, improving the efficiency of product carton packaging, and having use value.

[0005] Deficiencies in the prior art:

[0006] 1. Traditional packaging lines are usually designed to process products of specific sizes and shapes. For products with diverse specifications such as mid-rim basins, frequent manual adjustments of equipment are often required, which lacks flexibility, resulting in a low degree of automation and difficulty in quickly responding to changes in different batches of products, and unable to meet the market demand for high production changes;

[0007] 2. Due to the different sizes and specifications of incoming materials, frequent equipment adjustments and manual interventions restrict the operating efficiency of the production line, which not only increases production time, but also leads to higher failure rates and downtime, affecting the overall production efficiency and capacity;

[0008] 3. The existing packaging lines rely on workers to spend a lot of time and energy to arrange, adjust and pack products, which not only increases labor costs, but also may cause operator fatigue and work errors under high labor intensity, thus affecting production quality and safety.

[0069] Step 2: Snap the left and right sides together: The short folding edge lifting cylinder is started to drive the short folding edge into place;

[0070] Then, the short folding edge rotating cylinder starts to operate, folding the left and right lids to complete the closing of the left and right lids, while the short folding edge remains stationary;

[0071] Step 3: Upper clapping: The main lifting cylinder of the upper long folding edge is started first, and the upper folding edge is lowered to appropriately press down the upper cover of the carton;

[0073] Step 4: Finally, start the magnetic induction long folding cylinder 1 4, the magnetic induction long folding cylinder 2 5 and the magnetic induction long folding cylinder 3 6 to ensure that the upper cover is completely compacted;

[0074] Lower snap: first, the magnetic induction long folding cylinder 1 4, the magnetic induction long folding cylinder 2 5 and the magnetic induction long folding cylinder 3 6 are retracted and restored to their original positions;

[0075] Step 5: Then the upper folding edge auxiliary lifting cylinder rises, the magnetic induction long folding edge cylinder 49 is started, the lower folding edge is raised to appropriately press the lower end cover, and then the magnetic induction long folding edge cylinder 49 rises and returns to its original position, and finally the upper folding edge pushing cylinder is started to completely compact the cover and complete the ear flapping;

[0076] Release: After the clapping is completed, the magnetic long folding cylinder 1 4, the magnetic long folding cylinder 2 5 and the magnetic long folding cylinder 3 6 return to their original positions, releasing the carton, thereby allowing it to continue to move along the conveyor belt, and at the same time the next carton moves into position to repeat the adaptive sealing;

[0077] Step 6: After the carton is packed, the carton moves to the adaptive sealing module through the conveyor belt of the transport module for sealing. After receiving the signal that the carton has arrived, the adaptive sealing module uses the sensor to achieve precise positioning. At the same time, the servo motor will drive the ear-flapping device to automatically adjust the position and width to adapt to the size of the specific carton. When the position is adjusted to the right position, the ear-flapping device will perform the cover-flapping action, and then go to the sealing machine to seal the lid according to the carton size information.

[0078] Embodiment 1

[0079] like Figure 1 - Figure 8 As shown, the conveying module is composed of two belts, and the adaptive capping module is composed of a lifting and fixing cylinder, a short folding edge lifting cylinder, a short folding edge rotating cylinder, an ear-slapping device, an upper long folding edge main and auxiliary lifting cylinders, an upper folding edge pushing cylinder, a lower folding edge lifting cylinder, a lower folding edge pushing cylinder and a sealing machine;

[0080] The two modules together form an efficient carton sealing system. The conveying module uses two belts to achieve smooth transportation and storage of products, ensuring the continuity and precise delivery of cartons on the production line.

[0081] Embodiment 2

[0082] like Figure 1 - Figure 8 As shown, by starting the push motor 13 to push the push rod 15, the U-shaped photoelectric servo 23 and the limit frame 23 along the lower slide rail 14 and the upper slide rail 16 to adjust the width of the U-shaped photoelectric servo 23, the rotating rod 17 and the short folding edge beat ear 28;

[0083] Left and right clapping: the short folding edge lifting cylinder is started to drive the short folding edge into place;

[0084] Then, the short folding edge rotating cylinder starts to operate, folding the left and right lids to complete the closing of the left and right lids, while the short folding edge remains stationary;

[0085] Upper snap-on: The main lifting cylinder of the upper long folding edge is started first, lowering the upper folding edge to appropriately press down the upper cover of the carton;

[0086] Subsequently, the upper folding edge auxiliary lifting cylinder is started to appropriately press the cover down again, and the short folding edge flap ear 1 7 and the short folding edge flap ear 2 8 are withdrawn and restored to their original positions;

[0087] Finally, the magnetic induction long folding cylinder 1 4, the magnetic induction long folding cylinder 2 5 and the magnetic induction long folding cylinder 3 6 are started to ensure that the upper cover is completely compacted;

[0088] Lower snap: first, the magnetic induction long folding cylinder 1 4, the magnetic induction long folding cylinder 2 5 and the magnetic induction long folding cylinder 3 6 are retracted and restored to their original positions;

[0089] Then the upper folding edge auxiliary lifting cylinder rises, the magnetic induction long folding edge cylinder 49 is started, the lower folding edge is raised to appropriately press the lower end cover, and then the magnetic induction long folding edge cylinder 49 rises and returns to its original position, and finally the upper folding edge pushing cylinder is started to completely compact the cover and complete the ear flapping;

[0090] Release: After the clapping is completed, the magnetic long folding cylinder 1 4, the magnetic long folding cylinder 2 5 and the magnetic long folding cylinder 3 6 return to their original positions, releasing the carton, thereby allowing it to continue to move along the conveyor belt, and at the same time the next carton moves into position to repeat the adaptive sealing;

[0091] After packing, the carton is moved to the adaptive sealing module through the conveyor belt of the conveying module for sealing. After receiving the signal of the arrival of the carton, the adaptive capping module realizes precise positioning through the sensor. At the same time, the servo motor will drive the ear-slapping device to automatically adjust the position and width to adapt to the size of the specific carton. When the position is adjusted in place, the ear-slapping device will perform the cover-slapping action, and then go to the sealing machine to seal the lid according to the carton size information. The adaptive capping module integrates a variety of cylinders and sensor devices. According to the different sizes and shapes of the cartons, the action of each cylinder can be flexibly adjusted to realize adaptive folding of cartons of different specifications. The short folding lifting cylinder and the rotating cylinder cooperate with the ear-slapping device to effectively handle the short side folding of the carton and realize the preliminary processing of the capping.

[0092] The upper and lower long folding edge lifting cylinders and the pushing cylinders ensure that the long edges of the carton are folded in place to ensure the integrity of the closure;

[0093] The adaptive capping module works in coordination with the conveying module to ensure seamless connection and precise positioning of each link through a precise control system, thus achieving efficient carton sealing operations.
