For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0025] Combine the following Figure 1 , Figure 2 and Figure 3 The specific implementation of the straw assembly production line of the utility model is described.

[0026] The utility model provides a highly automated straw assembly production line, aiming to eliminate the limitations brought by manual operation. The straw assembly production line specifically includes: a first conveyor line 10, used for unidirectional conveying of a straw box 11, in which a straw assembly is installed; an unpacking workbench 20, arranged at the end of the first conveyor line 10, on which an unpacking mechanism for opening the lid of the straw box 11 is arranged; a grabbing robot 30, arranged on one side of the unpacking workbench 20, used for grabbing the straw assembly from the straw box 11 with the lid opened to the straw assembly machine 40; a second conveyor line 50, used for transporting the empty box back to the straw box 11, and the starting end of the second conveyor line 50 is arranged at an adjacent position to the unpacking workbench 20. The straw assembly production line realizes the automation of the entire process from automatic unpacking of the straw box 11, precise grabbing of the straw assembly to efficient return of the empty box, significantly improving production efficiency and reducing labor costs.

[0027] Specifically, as the starting point of the production line, the first conveyor line 10 is responsible for unidirectionally conveying the straw box 11 filled with straw assemblies. These straw assemblies are usually arranged neatly in the packaging box in advance to facilitate subsequent automated processing. The unpacking workbench 20 at the end of the first conveyor line 10 is integrated with an unpacking mechanism, which can automatically open the lid of the straw box 11 to prepare for the automatic grabbing of the straw assemblies. The grabbing robot 30 located on one side of the unpacking workbench 20 can accurately identify and grab single or grouped straw assemblies from the opened straw box 11, and then send them to the subsequent straw assembly machine 40 for further processing. In order to achieve effective recycling of resources, a second conveyor line 50 is also included, which is responsible for transporting the emptied straw box 11 from the vicinity of the unpacking workbench 20 back to the starting point or the designated recycling area. The starting end of the second conveyor line 50 is adjacent to the unpacking workbench 20, ensuring that the empty box can be removed immediately to avoid occupying the working space, and also leaving a channel for the subsequent delivery of the straw box 11 to maintain the smooth operation of the production line.

[0028] In order to further improve the degree of automation and operation accuracy, according to a straw assembly production line provided by the utility model, a visual recognition device is provided above or on the side of the first conveyor line 10 to identify the orientation of the straw box 11. Among them, the visual recognition device can capture and analyze the position and orientation of the straw box 11 on the conveyor line in real time through a high-resolution camera and advanced image processing algorithms, so as to help the unpacking mechanism to accurately align the box cover and prepare for smooth unpacking. On the other hand, in addition to locating the straw box 11, the visual system can preferably also perform preliminary quality inspections, such as monitoring whether the appearance of the straw box 11 is damaged, whether the straws in the box are neatly arranged, etc. Once an abnormality is detected, the system can issue an alarm in time to prevent unqualified materials from entering the subsequent production process.

[0029] In order to solve the problem of inconsistent orientation of the straw box 11 that may be encountered during the conveying process, according to a straw assembly production line provided by the utility model, at the upstream position of the unpacking workbench 20, the first conveyor line 10 includes a turning table 12; the upper surface of the turning table 12 is provided with an array roller assembly 13 composed of a plurality of drive rollers, and the operation mode of the array roller assembly 13 includes a conventional conveying mode and a turning mode; in the conventional conveying mode, the rotation directions of the plurality of drive rollers in the array roller assembly 13 are the same; in the turning mode, the directions of one part of the drive rollers in the array roller assembly 13 are opposite to those of another part of the drive rollers, so that the straw box 11 carried on the array roller assembly 13 rotates.

[0030] Among them, in the conventional conveying mode, all the drive rollers in the array roller assembly 13 rotate synchronously and in the same direction. This synergistic effect ensures that the straw box 11 can move forward smoothly and quickly along the conveyor line until it reaches the predetermined processing position, such as the unpacking workbench 20. When the system detects that the straw box 11 needs to adjust its orientation, the array roller assembly 13 will switch to the flip mode. At this time, a part of the drive rollers in the array will change the direction of rotation and form relative motion with another part of the rollers. This opposite rotational driving force acts on the bottom of the straw box 11, causing the straw box 11 to rotate a specific angle along the roller contact surface until it reaches the correct orientation. By combining these two operating modes, the flip table 12 can flexibly adapt to the processing needs of the straw box 11 in different situations, which not only improves the degree of automation of the production line, but also effectively avoids operation interruptions or errors caused by the wrong orientation of the straw box 11, further improving the overall production efficiency and the smoothness of the process.

[0031] Considering that the straw box 11 may be packaged with tape, according to a straw assembly production line provided by the utility model, a knife extension mechanism is provided above the first conveyor line 10 at the upstream position of the unpacking workbench 20, so as to cut the packaging tape above the straw box 11. The knife extension mechanism is equipped with a sharp and controllable cutting tool, such as an electric blade or a laser cutting head, and its position is adjustable so as to accurately align with the straw box 11 on the conveyor line. When the straw box 11 is transported to the predetermined position, the knife extension mechanism is started to quickly and accurately cut the packaging tape covering the opening of the straw box 11. In order to ensure the accuracy of the cutting process, the knife extension mechanism preferably works in conjunction with the visual recognition device described above. The visual system first identifies the position of the straw box 11 and the position of the tape, and then sends instructions to the knife extension mechanism to accurately adjust it to the optimal cutting position and depth to avoid damaging the straws in the box or the box itself. By automatically cutting the tape, the straw box 11 can be unpacked immediately after arriving at the unpacking workbench 20 without manual pause processing.

[0032] According to a straw assembly production line provided by the utility model, the grasping robot 30 is provided with a visual recognition component; the visual recognition component is located adjacent to the gripper 31 of the grasping robot 30 so as to move with the gripper 31. The visual recognition component equipped with the grasping robot 30 significantly improves the accuracy, efficiency and flexibility of straw grasping through follow-up visual monitoring and intelligent analysis. Preferably, the real-time visual feedback of the visual recognition component enables the grasping robot 30 to accurately locate each straw component, ensuring the accuracy of each grasping action and reducing the possibility of misgrasping or missing grasping. Based on visual information, the grasping robot 30 can dynamically adjust the posture, opening and closing degree and grasping path of its gripper 31 to adapt to straw components of different shapes, sizes or arrangements.

[0033] According to a straw assembly production line provided by the utility model, the straw assembly machine 40 is provided with a temporary storage box 41 for receiving assembled straws, and a waste box 42 for receiving straw components that failed to be assembled. Specifically, the temporary storage box 41 is located at the output end of the straw assembly machine 40, and is used to receive those straws that have been successfully assembled. These straws are usually finished products that have undergone strict quality inspection and assembly verification and meet production standards. The design of the temporary storage box 41 ensures that the assembled straws can be stacked or temporarily stored in an orderly manner, waiting for the next step of packaging or transfer to the downstream production line. The waste box 42 corresponds to the temporary storage box 41, and is arranged on the other side or a specific position of the straw assembly machine 40, and is specifically used to collect straw components that have not been successfully combined or do not meet quality requirements during the assembly process. These may include straws that have failed to assemble, are deformed, damaged, or tested unqualified. Through the automatic sorting mechanism, these waste materials will be directly sent to the waste box 42, avoiding mixing with qualified products and simplifying the subsequent processing process.

[0034] In order to ensure that the empty boxes can be quickly and accurately transferred from the unpacking workbench 20 to the second conveyor line 50, according to a straw assembly production line provided by the utility model, an overhead crane grabbing mechanism is arranged above the unpacking workbench 20 and the starting end of the second conveyor line 50, which is used to grab the empty straw box 11 from the unpacking workbench 20 to the starting end of the second conveyor line 50; or, a pushing mechanism is arranged on one side of the unpacking workbench 20, which is used to push the empty straw box 11 from the unpacking workbench 20 to the starting end of the second conveyor line 50.

[0035] Specifically, the overhead crane grabbing mechanism is preferably arranged above the unpacking workbench 20 and the starting end of the second conveyor line 50 as an automated handling solution for three-dimensional space operation. The overhead crane grabbing mechanism is usually equipped with a retractable mechanical arm and a grabbing fixture, which can grab the empty straw box 11 from above through a precise positioning control system, and then lift and move it horizontally to the starting position of the second conveyor line 50 and put it down.

[0036] As another option, a push mechanism can be configured on one side of the unpacking workbench 20. Usually, a mechanical device with a push plate or a push rod is used. When the straw box 11 is emptied on the unpacking workbench 20, the push mechanism is started to push the empty box horizontally to the starting end of the second conveyor line 50 next to it.

[0037] According to a straw assembly production line provided by the utility model, the second conveyor line 50 is parallel to the first conveyor line 10, and the conveying direction of the second conveyor line 50 is opposite to that of the first conveyor line 10. The parallel and opposite-direction layout can effectively utilize the lateral space of the factory or workshop, reduce the floor space of the production line, and allow managers to intuitively monitor the entire production process, making it easy to discover and solve problems. Among them, the first conveyor line 10 is responsible for inputting fully loaded straw boxes 11 to the unpacking workbench 20, while the second conveyor line 50 is responsible for moving the empty boxes from the unpacking workbench 20 and sending them back to the starting point or designated area. The reverse coordination of the two conveyor lines forms a closed-loop material circulation system, ensuring the continuity and efficiency of the production process.

[0038] According to a straw assembly production line provided by the utility model, the unpacking mechanism includes multiple groups of swing arms 21 and drivers 22 arranged around the unpacking workbench 20, and the inner side of the swing arm 21 is provided with a suction cup structure 23 for negative pressure adsorption of the box cover of the straw box 11; when the box cover is adsorbed by the suction cup structure 23, the swing arm 21 is driven by the driver 22 to swing, so that the box cover can be opened with the swing of the swing arm 21. Specifically, multiple groups of swing arms 21 are evenly arranged around the unpacking workbench 20, and are connected to the driver 22 (such as a servo motor or a pneumatic cylinder) by transmission. The inner side of each group of swing arms 21 is equipped with a special suction cup structure 23, which can tightly adsorb the box cover of the straw box 11 through the negative pressure pipeline or the negative pressure (vacuum) generated by the deformation of the suction cup structure 23. When the suction cup structure 23 successfully adsorbs the box cover, the driver 22 is started, and the swing arm 21 is controlled to swing regularly according to the preset program. As the swing arm 21 swings outward, the box cover is also moved by the traction force of the suction cup, and gradually opens.

[0039] According to a straw assembly production line provided by the utility model, a transmission shaft 24 is arranged between the swing arm 21 and the driver 22; the transmission shaft 24 is parallel to the edge of the straw box 11, and the swing arm 21 is vertically installed on the transmission shaft 24; in the axial direction of the transmission shaft 24, the installation position of the swing arm 21 is adjustable. The transmission shaft 24 is arranged parallel to the edge of the straw box 11, which ensures that the trajectory of the swing arm 21 when swinging is consistent with the opening direction of the box cover, thereby improving the accuracy of the unpacking action. It is particularly critical that the installation position of the swing arm 21 in the axial direction of the transmission shaft 24 is adjustable, so that it has extremely high flexibility, and the initial position of the swing arm 21 can be adjusted according to actual needs to adapt to straw boxes 11 of different specifications. Through this adjustable installation design, the production line can more flexibly respond to the needs of product diversification, reduce the cost of equipment modification or replacement caused by product changes, and is conducive to maintenance and debugging, so that technicians can quickly adjust according to actual conditions.
