Description

Technical Field

[0001] This invention relates to the field of light industrial machinery and equipment technology, and more specifically, to a cup material production line. Background Technology

[0002] In existing technologies, the assembly of cup materials mainly relies on manual operation. A typical production process involves manually aligning and assembling the cup body, base, and internal electronic components. This manual assembly method has significant drawbacks: firstly, it consumes a huge amount of labor, resulting in high production costs; secondly, due to human factors, problems such as improper installation and weak connections are prone to occur during prolonged repetitive labor, leading to poor product consistency and difficulty in ensuring quality stability.

[0003] Furthermore, after the initial assembly of the product, subsequent processes are required, such as pattern printing and quality inspection. Currently, these processes are usually carried out at different workstations, requiring operators to manually transfer and load / unload semi-finished or finished products between workstations. This method is not only time-consuming and labor-intensive, resulting in low production efficiency, but also leads to each dispersed workstation occupying a large amount of production space, resulting in a loose production line layout and low logistics efficiency, further restricting the improvement of production capacity and the optimization of production costs.

[0004] Therefore, there is an urgent need for an automated solution that can integrate multiple processes to overcome the many drawbacks of manual and decentralized operation modes. Summary of the Invention

[0005] The present invention aims to overcome at least one of the defects of the prior art and provide a cup material production line to solve the problems of dispersed processes and low level of automation.

[0006] The technical solution adopted by the present invention is to provide a cup material production line, wherein the cup material includes at least a base and a cup body having a first opening, and the base is configured to cover the first opening; The production line includes: A feeding assembly for placing the cup body and the base body; A feeding assembly is located downstream of the discharging assembly. The feeding assembly includes a feeding robotic arm and a first feeding mechanism and a second feeding mechanism located on the feeding robotic arm. The feeding robotic arm is used to drive the first feeding mechanism and the second feeding mechanism. The first feeding mechanism is used to pick up and release the cup body, and the second feeding mechanism is used to pick up and release the seat body. A loading platform is rotatably disposed downstream of the feeding assembly. The loading platform is used to receive the cup body released by the first feeding mechanism and the seat body released by the second feeding mechanism. An assembly component is located downstream of the feeding component. The assembly component includes an assembly mechanism, a first limiting mechanism, and a second limiting mechanism. The first limiting mechanism is used to position the cup body at a preset position on the platform, with the first opening of the cup body facing upward. The second limiting mechanism is used to continuously press the seat body down onto the first opening. The assembly mechanism is used to connect and fix the seat body to the cup body. A discharge assembly is located downstream of the assembly assembly and is used to remove the assembled cup material from the platform. A conveying assembly is connected between the assembly assembly and the discharge assembly, and the conveying assembly is used to transfer the loading platform.

[0007] In this invention, by integrating a first feeding structure and a second feeding mechanism into a feeding robotic arm, it is possible to achieve highly adaptable picking and dropping of cups, seats, or other materials, thereby improving the stability of material picking and transfer as well as the accuracy of material release. By integrating positioning, pressing, and connection fixing functions into the assembly components, and further combining the feeding components, discharge components, and conveying components in an orderly manner, all core steps from raw materials to finished product assembly are seamlessly connected in a coherent system. The physical space and work process are highly concentrated, eliminating breakpoints and waiting between processes, and effectively solving the problems of dispersed processes and low automation levels.

[0008] In some embodiments, the first feeding mechanism includes a cylinder component and a plurality of pneumatic grippers, the cylinder component being disposed on the feeding robotic arm, and the pneumatic grippers being movably disposed on the cylinder component; The pneumatic gripper has a limiting part on the side away from the cylinder component, and the inner wall of the cup body has a mating part with a shape matching the limiting part. The pneumatic gripper is used to extend into the cup body through the first opening of the cup body and press against the inner wall of the cup body when the first feeding mechanism picks up the cup body, so that the limiting part and the mating part are positioned and engaged.

[0009] In this invention, the first feeding mechanism uses a pneumatic gripper to extend into the inside of the cup to fix the two, which can avoid the potential damage risk to the appearance of the cup caused by grasping the outer surface of the cup. In addition, the positioning and cooperation between the limiting part of the pneumatic gripper and the mating part of the inner wall of the cup can improve the stability of the cup picking and transferring process, and help ensure that the cup is transferred to the preset position of the platform, which facilitates the alignment and assembly and fixation between the first opening of the cup and the base in the assembly process.

[0010] In some embodiments, the second feeding mechanism includes a connecting seat, a limiting member, and a first negative pressure device with a suction nozzle. The connecting seat is disposed on the feeding robot arm, the first negative pressure device is disposed on the connecting seat, and the limiting member is disposed on the connecting seat or the first negative pressure device. The limiting member has a limiting surface. When the second feeding mechanism picks up the seat, both the suction nozzle of the first negative pressure device and the limiting surface face the seat. The first negative pressure device sucks the seat tightly through the suction nozzle, and the limiting surface is spaced apart from or abuts against the seat.

[0011] In this invention, during the process of placing the seat over the first opening of the cup, a certain positional fine adjustment is required by the feeding robotic arm. The first negative pressure device is used for adsorption and fixation, which can reduce the contact area between the first feeding mechanism and the seat, making the seat more flexible when adjusting its position. In addition, the limiting component can limit or correct the longitudinal displacement of the seat, ensuring that the seat and the first opening of the cup are aligned in a preset manner, thus improving assembly efficiency.

[0012] In some embodiments, the limiting member is disposed on the connecting seat, the limiting member having a through hole extending from the limiting surface to the connecting seat, the first negative pressure device extending from the seat body toward the limiting surface through the through hole, and the air suction nozzle being exposed on the limiting surface.

[0013] In this invention, the limiting member is directly provided on the connecting seat, which has high installation stability. At the same time, the through hole can limit the first negative pressure device, improve the installation stability of the first negative pressure device, and make the orientation of the air suction nozzle stable, so as to reliably suck the seat body.

[0014] In some embodiments, the cup body has a second opening on the side facing the platform, and the platform has a boss with a shape matching the second opening. The cup body is positioned on the platform by fitting the second opening onto the boss. The first limiting mechanism includes a telescopic drive and a clamp. The clamp is connected to the drive end of the telescopic drive. The telescopic drive is located on one side of the conveying assembly. The clamp has a slot facing the cup. The telescopic drive drives the clamp by telescopic movement, so that the slot approaches and clamps the cup or moves away from the cup.

[0015] In this invention, the cup body is fitted with a protrusion through a second opening, which can provide the first positioning of the cup body. The cup body is limited from the outside by a clamp, which can provide the second positioning of the cup body. Thus, the cup body can be stably positioned at a preset position on the platform, making the assembly between the base and the cup body precise and efficient.

[0016] In some embodiments, the second limiting mechanism includes a pneumatic actuator and a movable rod. The pneumatic actuator is located on one side of the conveying assembly, and the proximal end of the movable rod is movably located at the driving end of the pneumatic actuator. The pneumatic actuator is configured to drive the movable rod such that the distal end of the movable rod swings toward the platform and presses down on the seat, or causes the distal end of the movable rod to float up and swing back to one side of the conveying assembly.

[0017] In this invention, the second limiting mechanism can perform two actions: swinging and pressing. When the movable rod is not pressing down, it swings to a preset position to avoid interfering with the actions of the assembly robot arm and the assembly mechanism. The movable rod presses the seat down onto the first opening of the cup body, so that the seat body does not shift during the assembly process of the assembly mechanism, thereby improving the assembly accuracy between the seat body and the cup body.

[0018] In some embodiments, the assembly mechanism includes: An assembly robotic arm, wherein the proximal end of the assembly robotic arm is located on one side of the conveying assembly, and the distal end of the assembly robotic arm is provided with a lifting component; A screw feeding device is located on one side of the conveying assembly and close to the assembly robot arm; A screw adsorption and tightening device is provided on the lifting component. The screw adsorption and tightening device is driven by the assembly robot arm and configured to adsorb screws from the screw feeding device and tighten the screws between the base and the cup.

[0019] In some embodiments, the conveying assembly includes: an upper conveyor belt, a lower conveyor belt, a first lifting mechanism, and a second lifting mechanism; The upper conveyor belt and the lower conveyor belt are arranged vertically. The upper conveyor belt is used to transport the platform from the assembly component to the discharge component, and the lower conveyor belt is used to transport the platform from the discharge component to the assembly component. The upper conveyor belt is connected to the lower conveyor belt at one end near the discharge component via the first lifting mechanism, and the lower conveyor belt is connected to the upper conveyor belt at one end near the assembly component via the lower second lifting mechanism.

[0020] In this invention, the loading platform loaded with finished cup materials is conveyed to the unloading component via an upper conveyor belt to complete the unloading. The unloaded loading platform can be lowered to the lower conveyor belt via a first lifting mechanism, and then sent back to the position corresponding to the assembly component via the conveying of the lower conveyor belt and the lifting action of the second lifting mechanism, so that the loading platform can achieve automated conveying. Furthermore, the conveying component of this invention can operate two loading platforms simultaneously. By having two loading platforms support the cup body and the base body, the interval time between two assembly can be shortened, thereby reducing the idle time of the production line and improving the production efficiency of cup materials.

[0021] In some embodiments, the discharge assembly includes: A multi-axis robot is positioned on one side of the conveying assembly; A receiving device is located downstream of the conveying assembly; The second negative pressure device is located on the multi-axis robot. Driven by the multi-axis robot, the second negative pressure device is configured to adsorb the assembled cup material and transfer it to the receiving device.

[0022] In some embodiments, the production line includes a frame, and the feeding assembly, the loading assembly, the assembly assembly, and the discharging assembly are sequentially arranged on the frame according to the flow direction of the cup material, and the conveying assembly is arranged on the frame between the assembly assembly and the discharging assembly.

[0023] In some embodiments, the production line further includes a laser engraving assembly disposed between the assembly assembly and the discharge assembly, the laser engraving assembly being located on one side of the conveying assembly, and the laser engraving assembly being used to engrave the outer surface of the cup material.

[0024] In some embodiments, the production line further includes a defective product station located between the assembly component and the discharge component, the defective product station being close to the discharge component and located on one side of the conveying component.

[0025] In some embodiments, the production line further includes a quality inspection component located between the assembly component and the discharge component, the quality inspection component being used to inspect the assembled cup materials to distinguish between qualified and unqualified products among the cup materials.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: by integrating the first feeding structure and the second feeding mechanism through the feeding robotic arm, it is possible to achieve highly adaptable picking and delivery of cups, seats or other materials; by integrating positioning, pressing and connecting fixing functions through the assembly components, and further combining the feeding components, discharging components and conveying components in an orderly manner, all core steps from raw materials to finished product assembly are seamlessly connected in a coherent system, effectively solving the problems of dispersed processes and low automation levels.

[0038] Example 1 like Figure 1 , 2 As shown in Figure 4, this embodiment provides a cup material production line. The cup material includes at least a base 2 and a cup body 1 with a first opening 12. The base 2 is configured to cover the first opening 12. The production line includes: The feeding assembly 100 is used to hold the cup body 1 and the base 2; The feeding assembly 200 is located downstream of the discharging assembly 100. The feeding assembly 200 includes a feeding robotic arm 210 and a first feeding mechanism 220 and a second feeding mechanism 230 located on the feeding robotic arm 210. The feeding robotic arm 210 is used to drive the first feeding mechanism 220 and the second feeding mechanism 230. The first feeding mechanism 220 is used to pick up and release the cup body 1, and the second feeding mechanism 230 is used to pick up and release the seat body 2. The platform 300 is rotatably located downstream of the feeding assembly 200. The platform 300 is used to receive the cup 1 released by the first feeding mechanism 220 and the seat 2 released by the second feeding mechanism 230. Assembly component 400 is located downstream of feeding component 200. Assembly component 400 includes assembly mechanism 410, first limiting mechanism 420 and second limiting mechanism 430. First limiting mechanism 420 is used to position cup body 1 at a preset position on platform 300. First opening 12 of cup body 1 is set upward. Second limiting mechanism 430 is used to continuously press seat 2 down on first opening 12. Assembly mechanism 410 is used to connect and fix seat 2 and cup body 1. The discharge component 500 is located downstream of the assembly component 400 and is used to remove the assembled cup material from the stage 300. The conveying component 600 is connected between the assembly component 400 and the discharge component 500, and the conveying component 600 is used for transferring the material to the transfer table 300.

[0039] In this embodiment, the production line includes a frame 700, a feeding assembly 100, a loading assembly 200, an assembly assembly 400, and a discharging assembly 500, which are sequentially arranged on the frame 700 according to the flow direction of the cup materials. A conveying assembly 600 is located on the frame 700 between the assembly assembly 400 and the discharging assembly 500. A platform 300 flows between the assembly assembly 400 and the discharging assembly 500 via the conveying assembly 600. In this way, all processes are integrated into a single production line, reducing the overall space occupied by the production line. Furthermore, the connections between the processes are compact and reliable, improving the production and flow efficiency of the cup materials.

[0040] In this embodiment, in order to reduce the feeding frequency, the feeding component 100 includes several feeding platforms and several conveyor belts. Each feeding platform is equipped with materials such as cup body 1 and seat body 2. The several conveyor belts are connected to each other. The feeding platforms are transported to the side close to the feeding component 200 by the conveyor belts in sequence, and the feeding component 200 is used to feed materials in sequence.

[0041] It is understood that the present invention integrates the first feeding mechanism 220 and the second feeding mechanism 230 through the feeding robotic arm 210, which can achieve highly adaptable picking and delivery of cup body 1, seat body 2 or other materials, and can improve the stability of material picking and transfer as well as the accuracy of material release; through the assembly component 400 integrating positioning, pressing and connection fixing functions, and further orderly combining the feeding component 100, the discharging component 500 and the conveying component 600, all core steps from raw materials to finished product assembly are seamlessly connected in a coherent system, the physical space and operation process are highly concentrated, eliminating the breakpoints and waiting between processes, and effectively solving the problems of dispersed processes and low level of automation.

[0042] Continue to refer to Figure 2 and 3 In some embodiments, the first feeding mechanism 220 includes a cylinder component 221 and a plurality of grippers 222. The cylinder component 221 is disposed on the feeding robot arm 210, and the grippers 222 are movably disposed on the cylinder component 221. The gripper 222 has a limiting part 223 on the side away from the cylinder component 221. The inner wall of the cup body 1 has a mating part 11 whose shape matches the limiting part 223. The gripper 222 is used to extend into the cup body 1 through the first opening 12 of the cup body 1 and press against the inner wall of the cup body 1 when the first feeding mechanism 220 picks up the cup body 1, so that the limiting part 223 and the mating part 11 are positioned and engaged.

[0043] In use, the first feeding mechanism 220 uses a pneumatic gripper 222 to extend into the cup body 1 to fix the two together. This avoids the potential damage to the appearance of the cup body 1 caused by gripping its outer surface. In addition, the positioning engagement between the limiting part 223 of the pneumatic gripper 222 and the mating part 11 of the inner wall of the cup body 1 improves the stability of the picking and transferring process of the cup body 1, helping to ensure that the cup body 1 is transferred to the preset position on the platform 300. This facilitates the alignment and assembly of the first opening 12 of the cup body 1 with the base 2 during the assembly process. Specifically, the inner wall of the cup body 1 is provided with several protruding ridges extending along the depth direction of the cup body 1. Two adjacent protruding ridges together with the corresponding inner wall of the cup body 1 form the mating part 11 of the groove. The limiting part 223 of the pneumatic gripper 222 is a protrusion whose shape fits into the groove of the inner wall of the cup body 1. It can be understood that by fitting the protrusion of the pneumatic gripper 222 into the groove of the inner wall of the cup body 1, a reliable positioning engagement between the pneumatic gripper 222 and the cup body 1 can be achieved.

[0044] In this embodiment, the second feeding mechanism 230 includes a connecting seat 231, a limiting member 232, and a first negative pressure device 233 with an air suction nozzle 234. The connecting seat 231 is disposed on the feeding robot arm 210, the first negative pressure device 233 is disposed on the connecting seat 231, and the limiting member 232 is disposed on the seat body 2 or the first negative pressure device 233. The limiting member 232 has a limiting surface. When the second feeding mechanism 230 picks up the seat body 2, the air suction nozzle 234 of the first negative pressure device 233 and the limiting surface are both facing the seat body 2. The first negative pressure device 233 sucks the seat body 2 tightly through the air suction nozzle 234, and the limiting surface is spaced apart from the seat body 2 or abuts against each other.

[0045] refer to Figure 7 In this invention, the side of the seat 2 facing the cup 1 is provided with several protruding structures 21. Some of these protruding structures 21 are located close to the edge of the seat 2. This means that when the feeding assembly 200 transfers the seat 2 to mate with the first opening 12 of the cup 1, if the seat 2 is aligned from top to bottom towards the first opening 12, high alignment accuracy is required. Otherwise, the alignment time between the seat 2 and the first opening 12 will be too long, affecting production efficiency. Figure 2To avoid the aforementioned disadvantages, the present invention uses a loading robotic arm 210 to move the seat 2 at a certain tilt angle, allowing the protruding structure 21 located at the edge of the seat 2 to first enter the cup body 1 through the first opening 12. Then, the loading robotic arm 210 moves the seat 2 downward, aligning the seat 2 with the first opening 12 of the cup body 1. It is understood that during the downward movement of the loading robotic arm 210, the seat 2 needs to be finely adjusted in position. The present invention uses a first negative pressure device 233 for adsorption and fixation, which can reduce the contact area between the first loading mechanism 220 and the seat 2, giving the seat 2 better flexibility when adjusting its position. In addition, the limiting member 232 can limit or correct the longitudinal offset of the seat 2, ensuring that the seat 2 and the first opening 12 of the cup body 1 are aligned in a preset manner, thus improving assembly efficiency.

[0046] In a preferred embodiment, the limiting member 232 is disposed on the connecting seat 231. The limiting member 232 has a through hole extending from the limiting surface to the connecting seat 231. The first negative pressure device 233 extends from the seat 2 toward the limiting surface through the through hole, and the air suction nozzle 234 is exposed on the limiting surface. It can be understood that the limiting member 232 is directly disposed on the connecting seat 231, which has high installation stability. At the same time, the through hole can limit the first negative pressure device 233, improve the installation stability of the first negative pressure device 233, and make the orientation of the air suction nozzle 234 stable, so as to reliably suction the seat 2.

[0047] In this embodiment, to accurately identify the cup 1, the seat 2, and other materials, the loading robotic arm 210 is also equipped with an image acquisition device. Specifically, the distal end of the loading robotic arm 210 is equipped with a mounting base, on which the first loading mechanism 220, the second loading mechanism 230, and the image acquisition device are all mounted. The loading robotic arm 210 drives the mounting base, thereby synchronously moving the first loading mechanism 220, the second loading mechanism 230, and the image acquisition device. Furthermore, the image acquisition device can also be used to identify and locate the position of the platform 300, so that the loading robotic arm 210 can accurately place the cup 1 and the seat 2 into preset positions on the platform 300. In specific implementation, to improve flexibility, the loading robotic arm 210 is a multi-axis robotic arm.

[0048] refer to Figure 4 , 6 7. In this embodiment, the cup body 1 has a second opening on the side facing the platform 300. The platform 300 is provided with a boss 310 whose shape matches the second opening. The cup body 1 is positioned on the platform 300 by fitting the second opening onto the boss 310. The first limiting mechanism 420 includes a telescopic drive member 421 and a clamp 422. The clamp 422 is connected to the drive end of the telescopic drive member 421. The telescopic drive member 421 is located on one side of the conveying assembly 600. The clamp 422 has a slot 423 facing the cup body 1. The telescopic drive member 421 drives the clamp 422 to move the slot 423 closer to and clamp the cup body 1 or away from the cup body 1. In a preferred embodiment, the telescopic drive member 421 can be implemented by a cylinder. The cylinder is fixed on the frame 700 by a fixed seat. It can be understood that the cylinder can shorten the execution time of the telescopic action and improve efficiency. It should be noted that the telescopic drive member 421 can also be implemented by a telescopic motor, screw, etc., which are well known to those skilled in the art and will not be described in detail here.

[0049] In practical use, the cup body 1 is fitted with a protrusion 310 through the second opening, which can provide the first positioning of the cup body 1. The cup body 1 is limited from the outside by the clamp 422, which can provide the second positioning of the cup body 1. Thus, the cup body 1 can be stably positioned in the preset position on the stage 300, so that the assembly between the seat 2 and the cup body 1 is precise and efficient.

[0050] refer to Figure 4 , 6 In this embodiment, the second limiting mechanism 430 includes a pneumatic actuator 431 and a movable rod 432. The pneumatic actuator 431 is located on one side of the conveying assembly 600. The proximal end of the movable rod 432 is movably located at the driving end of the pneumatic actuator 431. The pneumatic actuator 431 is configured to drive the movable rod 432, causing the distal end of the movable rod 432 to swing towards the platform 300 and press down on the seat 2, or causing the distal end of the movable rod 432 to float up and swing back to one side of the conveying assembly 600. It can be understood that through a pneumatic actuator 431, the second limiting mechanism 430 can perform two actions: swinging and pressing down. This allows the movable rod 432 to swing to a preset position when not performing the pressing action, avoiding interference with the actions of the assembly robot arm 413 and the assembly mechanism 410. The movable rod 432 presses the seat 2 down onto the first opening 12 of the cup body 1, preventing the seat 2 from shifting during the assembly process by the assembly mechanism 410, thus improving the assembly accuracy between the seat 2 and the cup body 1.

[0051] refer to Figure 5 In this embodiment, the assembly mechanism 410 includes: Assembly robot arm 413, the proximal end of assembly robot arm 413 is located on one side of conveying component 600, and the distal end of assembly robot arm 413 is provided with lifting component; The screw feeding device 411 is located on one side of the conveying assembly 600 and close to the assembly robot arm 413; The screw adsorption and tightening device 412 is located on the lifting component. Driven by the assembly robot arm 413, the screw adsorption and tightening device 412 is configured to adsorb screws from the screw feeding device 411 and tighten the screws between the base 2 and the cup 1.

[0052] In specific implementation, the screw adsorption and tightening device 412 includes an electric screwdriver 414 and an air cylinder 415. The electric screwdriver 414 is located on the lifting component. The air cylinder 415 has an air vent 418 and a channel penetrating its upper and lower end faces. The air vent 418 is connected to the channel. The bit of the electric screwdriver 414 enters from the first port 416 of the channel and extends to the second port 417 of the channel. The air vent 418 is connected to an external negative pressure device. The second port 417 of the channel is used to adsorb screws, and the bit is configured to rotate relative to the air cylinder 415. Thus, when the second port 417 adsorbs a screw, the bit of the electric screwdriver 414 can engage with the end groove of the screw. The assembly robot arm 413 transfers the screw to a preset position aligned with the base 2, and then the electric screwdriver 414 is activated, which tightens and fixes the screw at the connection between the base 2 and the cup 1.

[0053] refer to Figure 1 , 4 In this embodiment, the conveying assembly 600 includes: an upper conveyor belt 610, a lower conveyor belt 620, a first lifting mechanism 630, and a second lifting mechanism 640; The upper conveyor belt 610 and the lower conveyor belt 620 are arranged vertically. The upper conveyor belt 610 is used to transport the platform 300 from the assembly component 400 to the discharge component 500, and the lower conveyor belt 620 is used to transport the platform 300 from the discharge component 500 to the assembly component 400. The end of the upper conveyor belt 610 near the discharge component 500 is connected to the lower conveyor belt 620 through the first lifting mechanism 630, and the end of the lower conveyor belt 620 near the assembly component 400 is connected to the upper conveyor belt 610 through the lower second lifting mechanism 640.

[0054] In use, the platform 300 loaded with finished cup materials is conveyed to the unloading component 500 via the upper conveyor belt 610 to complete the unloading. The unloaded platform 300 can be lowered to the lower conveyor belt 620 via the first lifting mechanism 630, and then sent back to the position corresponding to the assembly component 400 via the conveying of the lower conveyor belt 620 and the lifting action of the second lifting mechanism 640, so that the platform 300 can achieve automated conveying. Furthermore, the conveying component 600 of the present invention can operate two platforms 300 at the same time. By having two platforms 300 support the cup body 1 and the seat body 2, the interval time between two assembly can be shortened, thereby reducing the empty transport time of the production line and improving the production efficiency of cup materials.

[0055] In practice, the upper conveyor belt 610 and the lower conveyor belt 620 are connected by multiple tracks, allowing multiple platforms 300 to be configured on both belts. By running or stopping different tracks, one platform 300 can remain at the assembly process where the assembly component 400 is located, while other platforms 300 loaded with finished cup materials can move to downstream processes. This reduces the idle time of the production line and improves production efficiency.

Driven by the multi-axis robot 510, the second negative pressure device 530 adsorbs the assembled cup material and transfers it to the receiving device 520 via the multi-axis robot 510.

[0057] refer to Figure 1 The production line also includes a laser engraving component 800 located between the assembly component 400 and the discharge component 500. The laser engraving component 800 is located on one side of the conveying component and is used to engrave the outer surface of the cup material.

[0058] refer to Figure 1 The production line also includes a defective product station located between the assembly component 400 and the discharge component 500. The defective product station is close to the discharge component 500 and located on one side of the conveying component. In specific implementation, the second negative pressure device 530 is also used to adsorb defective products, and the multi-axis robot 510 transfers the defective products to the defective product station.

[0059] refer to Figure 1 The cup material production line also includes a quality inspection component 900 located between the assembly component 400 and the discharge component 500. The quality inspection component 900 is used to inspect the finished cup materials to distinguish between qualified and unqualified products. In specific implementation, the quality inspection component 900 includes an image acquisition device and a main control device. The image acquisition device acquires images of the finished cup materials, and then the main control device analyzes the images to determine whether the cup materials are qualified.
