Description

Technical Field

[0001] This utility model relates to the field of cup printing technology, specifically to a testing mechanism for cup printing equipment. Background Technology

[0002] In existing technologies, the inspection and defective product handling of cup printing equipment are often carried out separately. Inspection is usually done manually by visual inspection, and it is not possible to automatically detect and monitor the printing process in real time. Defective product handling can only detect whether the cup is broken at the corona discharge point, and then the broken cups are removed at the waste cup return point, thus affecting overall production efficiency. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a testing mechanism for cup printing equipment, so as to solve the problem of reduced production efficiency caused by the fact that testing and defective product handling are often carried out separately, as mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides a detection mechanism for a cup printing device. The cup printing device includes a frame and a cup mold assembly. A separator output shaft is provided on one side of the frame along a first direction. The cup mold assembly includes a fixing ring, multiple cup mold shafts, and multiple cup molds. The fixing ring is located at the end of the separator output shaft. The multiple cup mold shafts are circumferentially spaced around the outer periphery of the fixing ring. Each cup mold corresponds to one of the multiple cup mold shafts, and each cup mold is located at the radial end of the cup mold shaft. The detection mechanism includes:

[0005] A visual inspection component, located on the side of the frame facing the cup mold component along the first direction, includes an industrial camera for photographing and identifying the product fitted onto the cup mold.

[0006] Each of the cup molds is provided with multiple air outlets at one end of the radial direction away from the fixing ring, as well as an air outlet chamber that communicates with each of the multiple air outlets.

[0007] The fixing ring has multiple first air inlets on the side facing the frame along the first direction, and each of the multiple first air inlets corresponds to one of the multiple cup mold shafts. Each cup mold shaft has a first air passage inside, which extends radially, communicates with the air outlet chamber at the top, and communicates with the first air inlet at the bottom. When the industrial camera detects a defective product, it blows the product off the cup mold by introducing air along the direction of the first air inlet, the first air passage, the air outlet chamber, and the air outlet.

[0008] This invention provides a detection mechanism for a cup printing equipment. An industrial camera can quickly and accurately photograph and identify products mounted on cup molds. Once a defective product is detected, it can be immediately blown off via an air path system, reducing intermediate steps and avoiding errors and time waste that may occur with manual operation. This integrated detection and rejection design greatly improves production efficiency. Each cup mold shaft has a first air path connected to a corresponding air outlet chamber and outlet. This design allows the blowing-off operation to be precise down to each cup mold. When the industrial camera detects a defective product on a cup mold, the corresponding air path system can blow off only that defective product without affecting other normal products.

[0009] In some embodiments, the detection mechanism further includes a drive sleeve, which is sleeved on the indexer output shaft and disposed between the fixed ring and the frame along the first direction, rotating relative to the indexer output shaft. One end of the drive sleeve that abuts against the fixed ring has an annular boss, and the annular boss has multiple second air passages inside, each corresponding to one of the multiple first air inlets.

[0010] By adopting the above technical solution, the presence of the drive sleeve makes the relative rotation between the fixed ring and the indexer output shaft smoother. The design of the annular boss not only provides space for the second air passage but also increases the rigidity of the structure, reducing vibration and loosening that may occur during equipment operation. The air source can be more evenly distributed to each of the first air inlets through the second air passage, and then reach the air outlet chamber and air outlet through the first air passage, ensuring that each cup mold receives a stable and sufficient airflow when blowing off defective products.

[0011] In some embodiments, the detection mechanism further includes a sleeve fitted over the outer side of the drive sleeve and abutting against the annular boss. The sleeve contains a plurality of third air passages extending along the first direction, each corresponding to a second air passage. The sleeve has an outward protrusion at one end along the first direction away from the annular boss, and the protrusion contains a plurality of second air inlets spaced circumferentially within it. These second air inlets correspond to the second air passages and are used to communicate with an external blowing device to blow air into the second air passages.

[0012] By adopting the above technical solution, the sleeve and the third air passage make the air intake of the air passage system more stable and uniform. The external blowing device can introduce gas into the third air passage through multiple air inlets, and then distribute it to each of the first air inlets through the second air passage, finally reaching the air outlet chamber and air outlet along the first air passage. This multi-stage air passage design can ensure that each cup mold receives a stable and sufficient airflow when blowing off defective products, improving the reliability of the blowing effect.

[0013] In some embodiments, the detection mechanism further includes a sealing portion disposed on the side of the outwardly protruding portion facing the cup mold assembly along the first direction, and surrounding the sleeve and the annular boss in the circumferential direction, for enhancing the airtightness of the second air passage and the third air passage. The outer surface of the sealing portion is provided with an annular groove extending in the circumferential direction.

[0014] By adopting the above technical solution, the sealing part makes the connection between the sleeve and the annular boss tighter, which can effectively reduce airflow leakage between the second and third air passages. This ensures that the airflow can efficiently pass from the external blowing device through the second air inlet, the third air passage, the second air passage, and the first air passage, finally reaching the air outlet chamber and the air outlet. This makes the airflow more concentrated and powerful when blowing off defective products, improving the reliability and consistency of the blowing effect.

[0015] In some embodiments, the vision inspection assembly further includes a sensor, a mounting bracket, a mounting plate, and a first connecting plate. The mounting plate is disposed on one side of the frame along a second direction and supports the industrial camera. One end of the mounting bracket is connected to the frame, and the other end is connected to the mounting plate. The first connecting plate extends along the first direction, with one end connected to the mounting bracket and the other end corresponding to the cup mold shaft. The sensor is disposed at the end of the mounting bracket near the cup mold shaft and is used to detect the position of the cup mold shaft.

[0016] Using the above technical solution, the sensor can monitor the position of the cup mold shaft in real time, ensuring that the cup mold shaft is in the correct position when the industrial camera takes pictures for recognition. The mounting plate is located on one side of the frame along the second direction and supports the industrial camera. During equipment installation or maintenance, the installation and positioning of the vision inspection components can be quickly achieved by adjusting the position of the fixing bracket and the mounting plate.

[0017] In some embodiments, the vision inspection assembly further includes an illumination strip and a second connecting plate. The illumination strip is disposed on the side of the industrial camera facing the cup mold assembly along the first direction, and the two ends of the second connecting plate are respectively connected to the illumination strip and the fixing frame.

[0018] By adopting the above technical solution, the presence of the lighting strip can ensure that the light on the product surface is uniform and sufficient during photo recognition, thereby improving the accuracy and reliability of the detection and avoiding detection errors caused by insufficient or uneven light.

[0019] In some embodiments, the detection mechanism further includes a drive assembly comprising a drive motor, a timing belt, and a motor mounting plate, the motor mounting plate being disposed on the other side of the frame along the second direction. The drive motor is fixedly connected to the motor mounting plate, and a drive shaft extending along the first direction is provided on the side facing the cup mold assembly along the first direction. The timing belt is sequentially wound between the drive shaft and the annular groove, for driving the sealing portion to rotate via the drive motor.

[0020] Using the above technical solution, the motor mounting plate is located on the other side of the frame along the second direction, separating the drive assembly from the vision inspection assembly to avoid affecting the recognition effect of the industrial camera. The drive motor can precisely control the rotation speed and angle, and transmit power to the sealing part and cup mold assembly through a synchronous belt, ensuring that each cup mold is in the correct position when detecting and blowing off defective products.

[0021] In some embodiments, the plurality of air outlets are spaced around the ends of the cup mold.

[0022] By adopting the above technical solution, multiple air outlets spaced around the end of the cup mold can form a uniform airflow distribution, ensuring that defective products are subjected to the same blowing force in all directions, thereby more effectively blowing defective products off the cup mold.

[0023] In some implementations, the sensor is either a position sensor or an infrared sensor.

[0024] Using the above technical solutions, the position sensor can accurately detect the position of the cup mold shaft, ensuring that the cup mold shaft is in the correct position when the industrial camera takes pictures for recognition. The infrared sensor, on the other hand, can detect the position of the cup mold shaft in a non-contact manner, avoiding wear and errors caused by mechanical contact. Both types of sensors can provide high-precision detection signals, improving the reliability and accuracy of the detection. Attached Figure Description

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] refer to Figures 1 to 4 , Figure 1 This diagram shows the connection of the detection mechanism of a cup printing device 1 according to an embodiment of the present invention; Figure 2 A perspective view of the detection mechanism of a cup printing device 1 provided in an embodiment of the present invention is shown; Figure 3 for Figure 2 A sectional view; Figure 4 This diagram shows a partial structural schematic of the detection mechanism of a cup printing device 1 provided in an embodiment of the present invention.

[0033] like Figures 1 to 4 As shown, the technical solution provided in this application is a testing mechanism for a cup printing device 1. The cup printing device 1 includes a frame 10 and a cup mold assembly 11. The frame 10 is along a first direction ( Figure 1 The indexer output shaft is located on one side (as shown in the X direction). The cup mold assembly 11 includes a retaining ring 12, multiple cup mold shafts 13, and multiple cup molds 14. The retaining ring 12 is located at the end of the indexer output shaft, and the multiple cup mold shafts 13 are arranged circumferentially (as shown in the X direction). Figure 2 Multiple cup molds 14 are spaced apart on the outer periphery of the fixing ring 12 (as shown in the θ direction). Multiple cup molds 14 are correspondingly arranged with multiple cup mold shafts 13. Each cup mold 14 is located on the cup mold shaft 13 along the radial direction (as shown in the θ direction). Figure 2 The end (as shown in the λ direction). The detection mechanism includes:

[0034] The visual inspection component 3 is located on the side of the frame 10 facing the cup mold component 11 along the first direction, and includes an industrial camera 30 for taking pictures and identifying the product fitted onto the cup mold 14.

[0035] Each cup mold 14 is provided with multiple air outlets 140 at one end radially away from the fixing ring 12, and an air outlet chamber 141 that is connected to the multiple air outlets 140.

[0036] The fixing ring 12 has multiple first air inlets 120 on the side facing the frame 10 along the first direction, and the multiple first air inlets 120 are arranged one-to-one with multiple cup mold shafts 13. Each cup mold shaft 13 has a first air passage 130 inside, which extends radially, with its top communicating with the air outlet chamber 141 and its bottom communicating with the first air inlet 120. When the industrial camera 30 detects a defective product, it blows the product off the cup mold 14 by introducing air along the direction of the first air inlet 120, the first air passage 130, the air outlet chamber 141, and the air outlet 140.

[0037] This application provides an inspection mechanism for a cup printing device 1. An industrial camera 30 can quickly and accurately photograph and identify products mounted on cup molds 14. Once a defective product is detected, it can be immediately blown off through an air path system, reducing intermediate steps and avoiding errors and time waste that may occur during manual operation. This integrated design of inspection and rejection greatly improves production efficiency. Each cup mold shaft 13 has a first air path 130 inside, connected to a corresponding air outlet chamber 141 and air port 140. This design allows the blowing-off operation to be precise down to each cup mold 14. When the industrial camera 30 detects a defective product on a cup mold 14, the corresponding air path system can blow off only the defective product without affecting other normal products.

[0038] In some embodiments, reference Figures 1 to 4 The testing mechanism also includes a drive sleeve 20, which is fitted onto the indexer output shaft and positioned between the fixed ring 12 and the frame 10 along the first direction, rotating relative to the indexer output shaft. An annular boss 21 is provided at one end of the drive sleeve 20 that abuts against the fixed ring 12. Multiple second air passages 210 are provided inside the annular boss 21, and each of the multiple second air passages 210 corresponds to one of the multiple first air inlets 120.

[0039] For example, the presence of the drive sleeve 20 makes the relative rotation between the fixed ring 12 and the indexer output shaft smoother. The design of the annular boss 21 not only provides space for the second air passage 210, but also increases the rigidity of the structure, reducing vibration and loosening that may occur during equipment operation. The air source can be more evenly distributed to each of the first air inlets 120 through the second air passage 210, and then reach the air outlet chamber 141 and the air outlet 140 through the first air passage 130, ensuring that each cup mold 14 can obtain a stable and sufficient airflow when blowing off defective products.

[0040] In some embodiments, reference Figures 1 to 4 The detection mechanism also includes a sleeve 22, which is fitted onto the outside of the drive sleeve 20 and abuts against the annular boss 21. The sleeve 22 has multiple third air passages 220 extending along a first direction, each corresponding to a second air passage 210. At the end of the sleeve 22 away from the annular boss 21 along the first direction, there is an outward protrusion 23. The outward protrusion 23 has multiple second air inlets 230 spaced circumferentially within it, each corresponding to a second air passage 210, for communication with an external blowing device to blow air into the second air passage 210.

[0041] For example, the arrangement of sleeve 22 and third air passage 220 makes the air intake of the air passage system more stable and uniform, and the overall air passage is as follows: Figure 3 As indicated by the dotted line, the external blowing device can introduce gas into the third air path 220 through multiple air inlets, and then distribute it to each of the first air inlets 120 through the second air path 210. Finally, it reaches the air outlet chamber 141 and the air outlet 140 along the first air path 130. This multi-stage air path design can ensure that each cup mold 14 can obtain a stable and sufficient airflow when blowing off defective products, thus improving the reliability of the blowing effect.

[0042] In some embodiments, reference Figures 1 to 4 The testing mechanism also includes a sealing part 24, which is located on the side of the outer protrusion 23 facing the cup mold assembly 11 in the first direction, and is arranged circumferentially around the sleeve 22 and the annular boss 21 to enhance the airtightness of the second air passage 210 and the third air passage 220. The outer surface of the sealing part 24 is provided with an annular groove 240 extending circumferentially.

[0043] For example, the sealing part 24 makes the connection between the sleeve 22 and the annular boss 21 tighter, which can effectively reduce the leakage of airflow between the second air passage 210 and the third air passage 220, and ensure that the airflow can efficiently reach the air outlet chamber 141 and the air outlet 140 from the external blowing device through the second air inlet 230, the third air passage 220, the second air passage 210, and the first air passage 130. This makes the airflow more concentrated and powerful when blowing off defective products, improving the reliability and consistency of the blowing effect.

[0044] In some embodiments, reference Figures 1 to 4 The visual inspection component 3 also includes a sensor 31, a mounting bracket 32, a mounting plate 33, and a first connecting plate 34. The mounting plate 33 is disposed on the frame 10 along the second direction ( Figure 1 The mounting bracket 32 ​​is located on one side (as shown in the Y direction) and supports the industrial camera 30. One end of the mounting bracket 32 ​​is connected to the frame 10, and the other end is connected to the mounting plate 33. The first connecting plate 34 extends along the first direction, with one end connected to the mounting bracket 32 ​​and the other end correspondingly disposed with respect to the cup mold shaft 13. The sensor 31 is disposed at the end of the mounting bracket 32 ​​near the cup mold shaft 13 and is used to detect the position of the cup mold shaft 13.

[0045] For example, the sensor 31 can monitor the position of the cup mold shaft 13 in real time, ensuring that the cup mold shaft 13 is in the correct position when the industrial camera 30 takes pictures for recognition. The mounting plate 33 is located on one side of the frame 10 along the second direction and supports the industrial camera 30. During equipment installation or maintenance, the installation and positioning of the vision inspection component 3 can be quickly achieved by adjusting the position of the fixing bracket 32 ​​and the mounting plate 33.

[0046] In some embodiments, reference Figures 1 to 4 The visual inspection component 3 also includes an illumination strip 35 and a second connecting plate 36. The illumination strip 35 is located on the side of the industrial camera 30 facing the cup mold component 11 along the first direction. The two ends of the second connecting plate 36 are respectively connected to the illumination strip 35 and the fixing bracket 32.

[0047] For example, the presence of the lighting strip 35 can ensure that the light on the product surface is uniform and sufficient during photo recognition, thereby improving the accuracy and reliability of the detection and avoiding detection errors caused by insufficient or uneven light.

[0048] In some embodiments, reference Figures 1 to 4The testing mechanism also includes a drive assembly, which comprises a drive motor 40, a timing belt 42, and a motor mounting plate. The motor mounting plate is located on the other side of the frame 10 along the second direction. The drive motor 40 is fixedly connected to the motor mounting plate, and a drive shaft 41 extending along the first direction is provided on the side facing the cup mold assembly 11 along the first direction. The timing belt 42 is sequentially wound between the drive shaft 41 and the annular groove 240, and is used to drive the sealing part 24 to rotate via the drive motor 40.

[0049] For example, the motor mounting plate is located on the other side of the frame 10 along the second direction, separating the drive assembly from the vision inspection assembly 3 to avoid affecting the recognition effect of the industrial camera 30. The drive motor 40 can precisely control the speed and angle of rotation, and transmits power to the sealing part 24 and the cup mold assembly 11 through the timing belt 42, ensuring that each cup mold 14 is in the correct position when detecting and blowing off defective products.

[0050] Specifically, the drive motor 40 drives the sealing part 24 to rotate via the synchronous belt 42. The cup mold assembly 11 also includes a drive ring 15, which is located on the side of the sealing part 24 facing the cup mold 14 in the first direction and is bolted to the sealing part 24. The drive plate and the bottom of the cup mold 14 are closely fitted together, so that the cup mold 14 rotates together with the drive ring 15, thereby keeping the cup mold 14 rotating at a constant speed throughout the printing process. During the printing process, the cup will pause briefly each time it rotates into the next station. During this period, the cup will still maintain stable rotation. The vision inspection equipment performs real-time detection when the cup mold 14 and the cup pause rotation at the station. The cup is detected several times for each rotation to ensure that all angles of the cup can be detected by the industrial camera 30 through rotation. The cup detection includes issues such as: registration deviation (≥0.2mm), printing position offset, printing defects, printing color monitoring (color difference threshold control), bubbles (≥1mm2), scratches, dirt, and impurities. After detecting abnormal cups, the abnormal cups are rejected through multiple air paths.

[0051] In some embodiments, reference Figures 1 to 4 Multiple air vents 140 are spaced around the end of the cup mold 14.

[0052] For example, multiple air outlets 140 spaced around the end of the cup mold 14 can form a uniform airflow distribution, ensuring that defective products are subjected to the same blowing force in all directions, thereby more effectively blowing defective products off the cup mold 14.

[0053] In some embodiments, sensor 31 is either a position sensor or an infrared sensor.

[0054] For example, a position sensor can accurately detect the position of the cup mold shaft 13, ensuring that the cup mold shaft 13 is in the correct position when the industrial camera 30 takes a picture for recognition. An infrared sensor, on the other hand, can detect the position of the cup mold shaft 13 in a non-contact manner, avoiding wear and errors caused by mechanical contact. Both types of sensors can provide high-precision detection signals, improving the reliability and accuracy of the detection.

[0055] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
