Description

TECHNICAL FIELD

[0001] The application relates to the technical field of a screen printing machine, in particular to a screen printing machine automatic detection and waste removal system. BACKGROUND

[0002] The screen printing machine is a device for printing images, texts, patterns or other designs on the surfaces of different materials, and the application range of the screen printing machine is very wide, and the screen printing machine can be used for printing various plastics, cosmetic packaging boxes, metal plates, electronic products and household products. It can also be used for printing on flat and curved surfaces, such as various types of cups, buckets, glasses and baseball bats.

[0003] After the screen printing machine completes product printing, the printed products need to be detected to check whether the products are qualified products, and currently, workers usually detect the products by naked eyes. However, the quality of the products detected by workers is poor, and unqualified products are not detected, and the detection speed is slow, thereby reducing the work efficiency of product quality detection. SUMMARY

[0004] In order to improve the work efficiency of printing product quality detection, the application provides a screen printing machine automatic detection and waste removal system.

[0005] The screen printing machine automatic detection and waste removal system provided by the application adopts the following technical scheme:

[0006] The screen printing machine automatic detection and waste removal system comprises a rack and a conveying part, the rack is installed at the output end of a screen printing machine, the conveying part is arranged on the top surface of the rack, a visual detection assembly is arranged on the top of the rack, the visual detection assembly is arranged on the top of the conveying part, the visual detection assembly is used for detecting whether the product is qualified, a clamping part is arranged on one side of the rack, the clamping part is arranged at the output end of the conveying part, a finished product transfer part is arranged on one side of the rack close to the clamping part, and a substandard product transfer part is arranged on the side of the finished product transfer part away from the rack.

[0007] Through the above technical scheme, after the product is printed by the screen printing machine, the product is transferred to the top surface of the conveying part from the output end of the screen printing machine, then the conveying part transfers the product to the bottom of the visual detection assembly, the detection assembly detects whether the product is qualified, the clamping part clamps the qualified product to the top surface of the finished product transfer part, and the unqualified product is placed on the top surface of the substandard product transfer part, so that the unqualified products are screened out.

[0008] The visual detection assembly is used for detecting the product, so that the labor of workers can be reduced, and the detection quality of the product by the application is higher than that by workers, the situation that unqualified products are not detected can be reduced, and the work efficiency of printing product quality detection can be improved.

[0009] Preferably, the end of the gripping member is provided with a finished product discharging member, and the end of the gripping member away from the conveying member is provided with a substandard product discharging member.

[0010] By using the above technical scheme, when the visual inspection assembly detects a substandard product, the finished product discharging member first grips and sends the product to the top surface of the finished product conveying member. At this time, the finished product conveying member receives a signal that the product is unqualified for quality inspection, and the finished product conveying member will stop conveying. Then, the finished product discharging member continues to return to grab the product on the next conveying member that has completed detection. At the same time, the substandard product discharging member is located at a position where it can grab the substandard product placed on the discharging conveying member, and a vacuum air source for the substandard product discharging member is also signaled. At this time, the finished product discharging member and the substandard product discharging member simultaneously adsorb the corresponding products. When the next operation is performed, the product adsorbed by the finished product discharging member will be sent to the top surface of the finished product conveying member, and the product adsorbed by the substandard product discharging member will be sent to the top surface of the substandard product conveying member, thereby completing the process of screening substandard products. When no substandard product is detected, the finished product conveying member does not stop, and the substandard product discharging member does not receive a signal. At this time, there is no vacuum air source, so the finished product cannot be grabbed.

[0011] Therefore, by using one gripping member, the effect of grabbing qualified products and unqualified products can be achieved, thereby saving resources. Compared with the case of using one finished product discharging member to sequentially grab substandard products and qualified products, the route of the gripping member in the present application is shorter, thereby further improving the work efficiency of printing product quality detection.

[0012] Preferably, the finished product discharging member is a finished product discharging suction cup.

[0013] By using the above technical scheme, the finished product discharging member is a finished product discharging suction cup. When the finished product discharging suction cup sucks the product, compared with the method of grabbing the product by using a gripper hand, the present application can reduce the situation of scratching the product.

[0014] Preferably, the finished product discharging suction cup has two, and the two finished product discharging suction cups are distributed along the width direction of the conveying member.

[0015] By using the above technical scheme, the two finished product discharging suction cups can suck the two ends of the product, thereby making the sucking of the product more stable and reducing the situation of the product falling during movement after being sucked.

[0016] Preferably, the extension direction of the finished product conveying member is perpendicular to the extension direction of the conveying member.

[0017] By adopting the above technical solution, the extension direction of the finished product transfer part is perpendicular to the extension direction of the conveying part, so that the distance between the finished product transfer part and the defective product transfer part is shorter, and the defective product discharge part can better absorb the defective products on the top surface of the finished product transfer part to the top surface of the defective product transfer part.

[0018] Preferably, the defective product discharging part is a defective product discharging suction cup.

[0019] By adopting the above technical solution, the defective product discharging piece is a defective product discharging suction cup, which can further reduce the situation of scratching the product.

[0020] Preferably, there are two defective product discharge suction cups, and the two defective product suction cups are distributed along the wide side direction of the conveying member.

[0021] By adopting the above technical solution, there are two defective product discharging suction cups, so that the two defective product discharging suction cups can be more stable when sucking up defective products.

[0022] Preferably, the visual detection component includes a light source unit and a camera, the camera is arranged on the top of the light source unit, and the output end of the camera is aligned with the top surface of the conveying member.

[0023] By adopting the above technical solution, with the cooperation of the light source unit and the camera, it is possible to better take photos of the products and compare the printed patterns to distinguish qualified products from defective products.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. After the product is printed by the screen printer, it enters the top surface of the conveyor from the output end of the screen printer. After that, the conveyor transfers the product to the bottom of the visual inspection component. The inspection component detects whether the product is qualified. The gripper clamps the qualified product to the top surface of the finished product transfer component and places the unqualified product on the top surface of the defective product transfer component, thereby screening out the products that fail the quality inspection.

[0026] This application uses visual inspection components to inspect products, which can reduce the labor of staff. At the same time, compared with the inspection by staff, the inspection quality of products inspected by mechanical means is higher, which can reduce the situation where defective products are not detected, and can also improve the work efficiency of printed product quality inspection.

[0027] 2. By using one clamping piece, qualified products and unqualified products can be clamped, thereby saving resources. At the same time, compared with the situation of using one finished product discharge piece to clamp defective products and qualified products in turn, the round-trip clamping route of this application is shorter, thereby further improving the work efficiency of printed product quality inspection.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The embodiments of the present application disclose an automatic detection and waste discharge system for a screen printing machine.

[0035] Reference Figure 1 and Figure 2 , the automatic detection and waste discharge system of the screen printing machine includes a detection device, which is arranged at the output end of the screen printing machine 7. The detection device includes a frame 1 and a conveyor 2. The frame 1 is installed on one side of the screen printing machine 7, and the conveyor 2 is arranged on the top surface of the frame 1. One end of the conveyor 2 corresponds to the output end of the screen printing machine 7. The conveying direction of the conveyor 2 is consistent with the conveying direction of the screen printing machine 7. The product enters the top surface of the conveyor 2 from the output end of the screen printing machine 7, and the conveyor 2 continues to convey the product. A visual inspection component 3 is provided on the top of the frame 1, and the visual inspection component 3 is located on the top of the conveyor 2. The visual inspection component 3 includes a light source unit 31 and a camera 32. The camera 32 is arranged on the top of the light source unit 31, and the output end of the camera 32 is aligned with the top surface of the conveyor 2. After the product is printed by the screen printing machine 7, the product enters the top surface of the conveyor 2 from the output end of the screen printing machine 7. After that, the conveyor 2 moves the product to the bottom of the visual inspection component 3, and with the cooperation of the light source unit 31 and the camera 32, the product is photographed and the printed pattern is compared to distinguish qualified products from defective products.

[0036] Reference Figure 3 and Figure 4, a clamping part is provided on one side of the frame 1. In the embodiment of the present application, the clamping part is a robot 4, which is located at the output end of the conveyor 2. A finished product discharging part is installed at the output end of the robot 4, and the finished product discharging part is a finished product discharging suction cup 41. The finished product discharging suction cup 41 is located at one end of the robot 4 close to the conveyor 2. There are two finished product discharging suction cups 41, and the two finished product discharging suction cups 41 are distributed along the wide side direction of the conveyor 2. Under the action of the finished product discharging suction cups 41, the products on the conveyor 2 that have completed the inspection can be sucked up, and the two finished product discharging suction cups 41 can suck up both ends of the product, so that the suction of the product can be more stable, reducing the situation where the product falls during the movement after being sucked up.

[0037] A defective product discharge piece is provided at the output end of the robot 4 away from the finished product discharge suction cup 41. In the embodiment of the present application, the defective product discharge piece is a defective product discharge suction cup 42. There are two defective product discharge suction cups 42, and the two defective product discharge suction cups 42 are distributed along the wide side direction of the conveying part 2.

[0038] A finished product transfer part is provided at the output end of the frame 1. In the embodiment of the present application, the finished product transfer part is a finished product conveyor belt 5. The extension direction of the finished product conveyor belt 5 is perpendicular to the extension direction of the conveying part 2, and the transfer direction of the finished product conveyor belt 5 is perpendicular to the transfer direction of the conveying part 2. Under the action of the finished product conveyor belt 5, qualified products can be transported.

[0039] Reference Figure 3 and Figure 4 Correspondingly, a defective product transfer part is provided on the side of the finished product conveyor belt 5 away from the frame 1. In the embodiment of the present application, the defective product transfer part is a defective product conveyor belt 6. The long side of the defective product conveyor belt 6 is parallel to the long side of the conveying member 2. The transfer direction of the defective product conveyor belt 6 is consistent with the transfer direction of the conveying member 2. The defective product conveyor belt 6 can transport unqualified products detected by the visual inspection component 3, thereby screening out products that fail the quality inspection.

[0040] When the visual inspection component 3 detects defective products, they are first sucked up by the finished product discharging suction cup 41 and sent to the top surface of the finished product conveyor belt 5. At this time, the finished product conveyor belt 5 receives a signal that the product is unqualified in quality inspection, and the finished product conveyor belt 5 will suspend transportation. After that, the finished product discharging suction cup 41 continues to go back to grab, and the finished product discharging suction cup 41 sucks the product that has completed the inspection on the next conveyor part 2. At the same time, the defective product discharging suction cup 42 is just located at a position where it can grab the defective products placed on the discharging conveyor belt, and also gives the signal to the defective product discharging suction cup 42 as a vacuum air source for suction. At this time, the finished product discharging suction cup 41 and the defective product discharging suction cup 42 simultaneously absorb the corresponding products. When the next action is performed, the product absorbed by the finished product discharging suction cup 41 will be sent to the top surface of the finished product conveyor belt 5, and the product absorbed by the defective product discharging suction cup 42 will be sent to the top surface of the defective product conveyor belt 6, thus completing the waste removal process. When no defective products are detected, the finished product conveyor belt 5 does not stop, and the defective product discharging suction cup 42 does not receive a signal. At this time, there is no vacuum air source, and the finished product cannot be grabbed.

[0041] The present application inspects products through the visual inspection component 3, which can reduce the labor of the staff. At the same time, compared with the inspection by staff, the inspection quality of the products inspected by mechanical means is higher, which can reduce the situation where defective products are not detected, and can also improve the work efficiency of printed product quality inspection.

[0042] The above are all preferred embodiments of the present application. These embodiments are only explanations of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
