Description

Technical Field

[0001] The present invention belongs to the technical field of thermos cup visual inspection, and in particular relates to a cup body defect inspection device based on vision. Background Art

[0002] As an indispensable part of our daily life, the insulated cup has an exquisite design and diverse functions, allowing us to enjoy the appropriate temperature of drinks whether in the hot summer or the cold winter.

[0003] As people's living standards continue to improve, fitness exercises are becoming more and more popular in daily life. Thermos cups play an increasingly important role in fitness exercises, especially in maintaining good water supply and keeping the ideal temperature of drinks. Therefore, when exercising, people generally carry thermos cups with them, especially some professional fitness and fitness enthusiasts, who will carry thermos cups and other items when going to the gym.

[0004] However, the existing thermos cup has the following defects when used in the above scenarios and during the production process: 1. Some professional fitness enthusiasts generally need to not only replenish water during fitness, but also add various substances to the water to replenish the energy needed by the body, such as protein powder, electrolytes, etc. These substances need to be placed in a water cup in a certain amount before mixing, and then add water for mixing. During the adding process, these powder substances are deposited at the bottom of the cup, and are easy to clump when adding water. It takes a long time to shake or stir to fully dissolve in the water, which is very troublesome.

[0005] 2. During fitness, you need to constantly replenish water, so the volume of thermos cups used for fitness is generally large. When used in other scenarios, they are too large to be used and carried.

[0006] 3. During the production of thermos cups, the surface of the cup body needs to be inspected after production to determine whether there are any defects on the surface, so as to facilitate the screening of inferior products. However, the existing detection devices generally detect the surface of the cup body by mechanical claw clamping or suction cup adsorption and then rotating. However, mechanical claw clamping and suction cup adsorption will cover part of the surface of the cup body, resulting in this part of the surface cannot be detected, requiring multiple misaligned detections, resulting in low detection efficiency, and discontinuous detection, which will lead to reduced detection accuracy. Summary of the invention

[0007] The purpose of the present invention is to provide a cup body defect detection device based on vision, which can make the brewing material dissolve in water at a higher rate, improve the brewing efficiency, and be more convenient to use. At the same time, the cup body detection efficiency is high and the detection accuracy is higher.

[0009] The cup body comprises a cup cover, a cup body connected to the cup cover, and a storage cover arranged in the inner cavity of the cup body; The storage cover is used for placing brewing materials and is suspended in the inner cavity of the cup body in a magnetic manner. Under external force, the storage cover can rotate to mix the brewing materials with water.

[0010] As a preferred solution, the magnetic attraction method is to symmetrically embed a first strong magnetic column in the outer wall of the storage cover and symmetrically embed a second strong magnetic column in the inner wall of the cup body, and the first strong magnetic column and the second strong magnetic column have opposite polarities.

[0011] As a preferred solution, the storage cover includes a cover body and a cover cover that are engaged with each other, through holes are evenly opened on the cover cover, and the first strong magnetic columns are symmetrically embedded in the outer side wall of the cover body.

[0012] As a preferred solution, the height of the cover body is greater than three quarters of the overall height of the storage cover, and is integrally injection-molded from a transparent plastic material. The outer surface of the cover body is integrally molded with scale lines. The cover cover is integrally molded from a metal material by stamping, and its mass is greater than that of the cover body.

[0013] As a preferred solution, the cup body is a segmented structure, and is formed by a cup mouth, a middle section and a bottom support portion which are connected to each other by threads; The top of the cup mouth part is integrally formed with a cup mouth connected to the cup cover, and the bottom inner wall is provided with a first threaded groove, the top of the middle section part is integrally formed with a first threaded opening, and the bottom inner wall is provided with a second threaded groove, the top of the base part is integrally formed with a second threaded opening, the first threaded groove is completely consistent with the second threaded groove, and the first threaded opening is completely consistent with the second threaded opening.

[0014] As a preferred embodiment, the cup body is ringed with an elastic anti-slip sleeve, and the cup mouth, middle section and bottom support are symmetrically embedded with second strong magnetic columns matching the first strong magnetic columns, the middle section is integrally formed with a first convex ring at the bottom of the first threaded mouth, and the bottom support is integrally formed with a second convex ring at the bottom of the second threaded mouth.

[0015] As a preferred solution, the polarity of the magnetic attraction portion is opposite to that of the second strong magnetic column, and the magnetic attraction portion is a cylindrical magnet or an electromagnet.

[0016] As a preferred solution, the circumferential pushing mechanism includes a rotating support rotatably mounted on the top bracket, a pushing cylinder fixedly mounted on the rotating support, and a second servo motor vertically mounted on the top bracket, the power output end of the second servo motor is connected to a driving gear through a coupling, the top of the rotating support is fixedly sleeved with a driven gear ring meshing with the driving gear, and the clamping support is fixedly mounted on the power output end of the pushing cylinder.

[0017] As a preferred solution, the CCD camera located on the side of the detection platform is provided with a linear drive mechanism for driving it to perform linear motion relative to the cup body to be detected, which includes a linear track support plate fixedly mounted on the detection platform, a slide seat slidably mounted on the linear track support plate, and a first servo motor fixedly mounted on the linear track support plate, a nut seat is fixedly mounted on the slide seat, and the power output end of the first servo motor is connected to a screw threadedly connected to the nut seat through a coupling transmission.

[0018] The technical effects achieved by the present invention are: The thermos cup of the present invention provides a storage cover inside the cup body, and provides a first strong magnetic column and a second strong magnetic column to magnetically suspend the storage cover. When the brewing material is placed inside the storage cover and water is added, the storage cover will continuously flip around the magnetic axis under the action of the water flow, and gradually scatter the powder into the water through the through holes, thereby reducing the formation of lumps and making the brewing material and water mix more evenly. At the same time, when the user shakes the thermos cup, the back and forth flowing water will also make the storage cover continuously flip around the magnetic axis, thereby acting as a stirring rotor, so that the brewing material dissolves faster in the water, the brewing efficiency is improved, and the use is more convenient.

[0019] The thermos cup in the present invention has a storage cover with a multi-section structure, and the sections are connected by threads.

[0020] The cup body defect detection device in the present invention can be matched with the second strong magnetic column in the thermos cup by setting a magnetic support claw and cooperating with the magnetic suction part, and can detect and clamp the cup body through magnetic suction force. Compared with the existing technical means, it does not produce direct contact with the cup body and will not cover the surface of the cup body, so that the surface of the cup body can be continuously and uninterruptedly inspected 360° around the surface without multiple inspections. While improving the inspection efficiency, the inspection is continuous, so that the inspection accuracy is improved, and the modification cost is low, which is easy to promote.

[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0024] like Figure 9-Figure 16 As shown, a vision-based cup body defect detection device is used to detect the cup body 2 of the thermos cup in Example 1 and Example 2, including a CCD camera 7 and a clamping part 8 installed on a detection platform.

[0025] Embodiment 1: like Figure 1-Figure 3 As shown, the device is used to detect a cup body 2 , which includes a cup cover 1 , the cup body 2 connected to the cup cover 1 , and a storage cover 3 arranged in the inner cavity of the cup body 2 .

[0026] Among them, the storage cover 3 is used to place the brewing material, and the brewing material here can be powder, hydrogel, liquid, tea and other common materials that are mixed with water for drinking. The storage cover 3 is magnetically suspended in the inner cavity of the cup body 2. Under the action of external force, the storage cover 3 can rotate to fully mix the brewing material with water, so as to improve the efficiency of various substances dissolving in water and facilitate users to drink.

[0027] Refer to the attached Figure 3 The storage cover 3 includes a cover body 31 and a cover 32 that are engaged with each other, and through holes 321 are evenly opened on the cover 32. The brewing material can be placed on the cover body 31, and the cover 32 is covered on the cover body 31 to seal it. Then, the storage cover 3 is placed into the cup body 2. During the mixing process with water, if it is a flowable substance such as powder, hydrogel, liquid, etc., it can flow out through the through hole 321 and dissolve in the water; if it is a non-flowable substance such as tea, water can enter the storage cover 3 through the through hole 321 to soak it, and then diffuse out to complete the fusion with water; this embodiment is described by taking the placement of powder in the storage cover 3 as an example.

[0028] Refer to the attached Figure 2-Figure 3 In this embodiment, the magnetic attraction method is a first strong magnetic column 4 symmetrically embedded in the outer wall of the cover body 31 and a second strong magnetic column 5 symmetrically embedded in the inner wall of the cup body 2. The first strong magnetic column 4 and the second strong magnetic column 5 have opposite polarities and are placed opposite to each other with a gap between them, which can reduce the obstruction to the water flow and avoid the retention of brewing materials. At the same time, through the principle of opposite magnetic attraction, the lateral magnetic attraction between the first strong magnetic column 4 and the second strong magnetic column 5 is used to magnetically suspend the storage cover 3 between the two groups of second strong magnetic columns 5 arranged symmetrically in the transverse direction to form an invisible magnetic attraction axis; thereby, when adding During the process of mixing the water, under the impact of the water flow, the storage cover 3 will continuously flip around the magnetic axis, and use the centrifugal force to gradually scatter the powder into the water through the through hole 321, thereby reducing the formation of lumps and making the brewing material and water mix more evenly. At the same time, when the user shakes the thermos cup, the water flowing back and forth in the cup body 2 will also make the storage cover 3 continuously flip around the magnetic axis, thereby acting as a stirring rotor, so that the brewing material dissolves in the water at a higher rate, improves the brewing efficiency, and is more convenient to use; and the magnetic suction method is also easy to disassemble, which is convenient to remove for cleaning.

[0029] In other embodiments, the first strong magnetic pillar 4 and the second strong magnetic pillar 5 may be directly arranged in contact with each other, and may be arranged according to specific needs.

[0030] In this embodiment, three groups of second strong magnetic columns 5 are arranged in the cup body 2, which are arranged at the top, middle and bottom of the cup body 2 respectively. When placing the storage cover 3, different placement positions can be selected according to different brewing objects. For example, when placing flowable materials such as powder, it can be placed in the middle or top to facilitate full dissolution, and the stirring range is wider when shaking and stirring; when placing non-flowable soaking objects such as tea leaves, it can be placed at the bottom so that it can be fully in contact with water, and there will be no phenomenon of no contact with water when the water is continuously reduced.

[0031] Of course, in other embodiments, at least one group of second strong magnetic columns 5 is arranged in the cup body 2 , and can be arranged at the top, middle and bottom of the cup body 2 as needed.

[0032] Refer to the attached Figure 3 In the present embodiment, in order to facilitate quantitative taking of powdered substances, the height of the cover body 31 is greater than three quarters of the overall height of the storage cover 3, thereby increasing the volume for placing powdered substances and better meeting user needs. The cover body 31 is integrally injection-molded from a transparent plastic material, and a scale line 311 is integrally formed on the outer surface of the cover body 31. Users can accurately grasp the amount of water dissolved in the powdered substance, thereby making the taste of the mixed beverage better and meeting various user needs.

[0033] The plastic material is one of polycarbonate (PC), polypropylene (PP), Trita copolyester, acrylonitrile-styrene copolymer (AS) and ECOZEN. The present embodiment uses Trita copolyester.

[0034] Furthermore, in order to ensure that the powder is fully dissolved, the cover 32 is stamped and formed in one piece from a metal material, and its mass is greater than that of the cover body 31. In this way, after the storage cover 3 is continuously flipped, the cover 32 as the heavier end will flip to the bottom under the action of gravity, toward the bottom of the cup, thereby facilitating the complete pouring of the substance inside into the water through the through hole 321 to avoid retention inside, and at the same time, non-flowing substances such as tea leaves can also better contact with water.

[0035] The metal material is one of stainless steel, aluminum alloy, copper alloy and titanium alloy, and this embodiment uses stainless steel.

[0036] Of course, in other embodiments, the cover body 31 and the cover 32 can be made of other suitable materials, including but not limited to plastic and metal materials, and the materials of the two materials can be the same or different.

[0037] Refer to the attached Figure 1 The cup body 2 is covered with an elastic anti-skid sleeve 6, which makes it more comfortable for users to hold the cup and also plays an anti-skid role to prevent the cup from slipping out of the hand.

[0038] Embodiment 2: like Figure 4-Figure 8 As shown, this embodiment is basically the same as the first embodiment, and the only difference is that: Refer to the attached Figure 4 The device is used to detect the cup body 2. The cup body 2 is a segmented structure, which is composed of a cup mouth 21, a middle section 22 and a bottom support 23 that are connected to each other by threads. When a smaller thermos cup is needed, the middle section 22 can be removed, and the cup mouth 21 and the bottom support 23 can be assembled to form a new small-capacity thermos cup, which is more convenient to carry and meets current needs, making the thermos cup more widely used to meet various needs of users.

[0039] Refer to the attached Figure 5-Figure 7 The top of the cup mouth 21 is integrally formed with a cup mouth 211 connected to the cup cover 1, and the bottom inner wall is provided with a first thread groove 212, the top of the middle section 22 is integrally formed with a first thread opening 221, and the bottom inner wall is provided with a second thread groove 222, and the top of the bottom support 23 is integrally formed with a second thread opening 231, and the first thread groove 212 is completely consistent with the second thread groove 222, and the first thread opening 221 is completely consistent with the second thread opening 231, so that the cup mouth 21, the middle section 22 and the bottom support 23 can be arbitrarily selected to be combined in pairs, and then when the user needs, the cup mouth 21, the middle section 22 and the bottom support 23 can be combined to form a large-volume cup body 2; the cup mouth 21 and the bottom support 23 are combined to form a small-volume cup body 2 (such as the attached Figure 8 as shown).

[0040] Refer to the attached Figure 4-Figure 8 In order to magnetically connect with the storage cover 3, a second strong magnetic column 5 matching the first strong magnetic column 4 can be symmetrically embedded in the cup mouth 21, the middle section 22 and the bottom support 23, so that the storage cover 3 can be magnetically attracted regardless of whether a large-volume cup body 2 or a small-volume cup body 2 is used.

[0041] Furthermore, in this embodiment, the middle section 22 is integrally formed with a first convex ring 223 at the bottom of the first threaded opening 221, and the bottom support section 23 is integrally formed with a second convex ring 232 at the bottom of the second threaded opening 231, and the elastic anti-slip sleeve 6 is sleeved between the first convex ring 223 and the second convex ring 232, so that the threaded connection gap between the cup mouth 21, the middle section 22 and the bottom support section 23 can be covered (as shown in the attached figure). Figure 8 As shown on the left, it improves the aesthetics and also improves the heat preservation performance; at the same time, since the elastic anti-slip sleeve 6 can be appropriately deformed according to the shape of the cup body, when a small-volume cup body 2 is formed by combining the cup mouth portion 21 and the bottom support portion 23, the elastic anti-slip sleeve 6 can also be put on the cup body 2 to cover the threaded connection gap (such as the attached Figure 8 As shown on the right), it improves aesthetics while also improving thermal insulation performance.

[0042] Of course, in other embodiments, the first convex ring 223 and the second convex ring 232 may not be provided, and the selection may be made according to processing and process requirements.

[0043] Embodiment three: Refer to the attached Fig. 9 A group of CCD cameras 7 are respectively arranged on the side and bottom of the detection platform. At the same time, an optical lens 76 is installed at the shooting end of the CCD camera 7. At the same time, a ring light source 78 is installed on the top bracket through a ring bracket 77, and the ring light source 78 surrounds the periphery of the clamping part 8, which can illuminate the four sides of the cup body 2 during detection to improve the shooting clarity.

[0044] Refer to the attached Fig. 9 as well as Fig.12 In order to expand the detection range of the CCD camera 7 on the side of the detection platform, a linear track support plate 71 is fixedly installed on the detection platform, and a slide 72 is slidably installed on the linear track support plate 71. At the same time, a first servo motor 74 is fixedly installed on the linear track support plate 71. A nut seat 73 is fixedly installed on the slide 72, and a screw rod 75 threadedly connected to the nut seat 73 is connected to the power output end of the first servo motor 74 through a coupling transmission. The first servo motor 74 can be used to drive the screw rod 75 to rotate, and then the reciprocating movement of the nut seat 73 on the screw rod 75 can be used to drive the CCD camera 7, the optical lens 76 and the slide 72 to move linearly along the track on the linear track support plate 71, thereby expanding the detection range of the CCD camera 7 and making its detection of the cup body 2 more comprehensive.

[0045] Secondly, the CCD camera 7 located at the bottom of the detection platform is arranged to look upward through an adjustable tilt bracket, so that it can pass through the central through hole of the detection platform to perform visual detection on the bottom of the cup body 2.

[0046] Refer to the attached Fig.10 as well as Fig.11 The clamping portion 8 includes a magnetic claw mechanism for magnetically limiting the cup body 2 and a circumferential pushing mechanism for driving the magnetic claw assembly.

[0047] Please refer to the attached Fig.11 The magnetic claw mechanism includes a clamping support 81, a magnetic claw 82 installed in the clamping support 81 in a transversely staggered sliding manner, and a magnetic portion 83 fixedly embedded in the bottom end of the magnetic claw 82. At the same time, the magnetic portion 83 has an opposite polarity to the second strong magnetic column 5, so that the cup body 2 can be detected and clamped by magnetic attraction without direct contact with the cup body 2 and will not cover the surface of the cup body 2.

[0048] In this embodiment, the magnetic attraction portion 83 is a cylindrical magnet, which can save costs.

[0049] Of course, in other embodiments, the magnetic attraction portion 83 may be an electromagnet, which is powered on when the cup body 2 is attracted, and powered off when the detection is completed and the cup is taken out, making it more convenient to take. Compared with using a cylindrical magnet, there is no need to use a clamping claw with greater force.

[0050] Furthermore, the magnetic support claw 82 is integrally formed with a positioning slide bar 84 on its top, and slide grooves 86 are symmetrically opened at both ends of the clamping support 81, and the positioning slide bar 84 is slidably inserted into the slide groove 86, and then a positioning bolt 85 is threadedly connected to the slide groove 86 on the side of the clamping support 81. The two groups of positioning slide bars 84 can be relatively slid in the slide groove 86 to change the distance between the two groups of magnetic support claws 82, thereby improving their adaptability and being able to magnetically attract cup bodies 2 of different calibers. After adjustment, the positioning slide bar 84 can be fixed in position by rotating the positioning bolt 85 so that it will not move easily during use, thereby ensuring stability in use.

[0051] Please refer to the attached Fig.10 The circumferential pushing mechanism includes a rotating support 88 rotatably mounted on the top bracket, a pushing cylinder 87 fixedly mounted on the rotating support 88, and a second servo motor 810 vertically mounted on the top bracket. A driving gear 811 is connected to the power output end of the second servo motor 810 through a coupling transmission. At the same time, a driven gear ring 89 meshing with the driving gear 811 is fixedly sleeved on the top of the rotating support 88. The second servo motor 810 can drive the pushing cylinder 87 through the meshing driving gear 811 and the driven gear ring 89. The whole body rotates circumferentially, and the clamping support 81 is fixedly installed on the power output end of the pushing cylinder 87, which can drive the cup body 2 magnetically attracted to the magnetic support claw 82 to rotate circumferentially, so that the CCD camera 7 can continuously and uninterruptedly detect the surface of the cup body 2 at 360° without multiple detections. While improving the detection efficiency, the detection is continuous, so that the detection accuracy is improved. At the same time, the pushing cylinder 87 can control the magnetic support claw 82 to enter or leave the interior of the cup body 2 through the extension and retraction of its power output end to avoid obstruction to the movement of the cup body 2.

[0052] See attached Fig.13 as well as Fig.14In order to take the cup body 2, the present embodiment is also provided with a conveying part 9, which includes a linear support 91 fixedly mounted on the production bracket, an arm slide 92 symmetrically slidably mounted on the linear support 91, and a first pneumatic clamping claw 93 and a second pneumatic clamping claw 94 symmetrically mounted on two groups of arm slides 92. A positioning screw 95 is installed between the two groups of arm slides 92 to adjust the distance between them, so that the first pneumatic clamping claw 93 and the second pneumatic clamping claw 94 can be placed just on both sides of the detection platform, and can clamp the undetected cup body 2 and the detected cup body 2 respectively. At the same time, a linear drive cylinder 96 is fixedly mounted on the bottom of the linear support 91, and the power output end of the linear drive cylinder 96 is fixedly mounted on the bottom of one of the arm slides 92. The linear drive cylinder 96 can be used to push the first pneumatic clamping claw 93 and the second pneumatic clamping claw 94 to move synchronously through the arm slide 92, thereby completing the alternating displacement transmission of the undetected cup body 2 and the detected cup body 2.

[0053] According to the above structure, when the cup body 2 is inspected, the present embodiment firstly conveys the cup body 2 with the opening facing upward to the inspection platform one by one at equal distances through the conveyor line 10. After the cup body 2 is conveyed to the clamping range of the first pneumatic clamping claw 93, the conveyor line 10 stops, and the first pneumatic clamping claw 93 is started to clamp the cup body 2. Then, the power output end of the linear drive cylinder 96 retracts to move the cup body 2 to the bottom of the power output end of the push cylinder 87. After that, the power output end of the push cylinder 87 extends and pushes the magnetic support claw 82 into the cup body 2. The magnetic attraction part 83 and the second strong magnetic column 5 are used to complete the clamping of the cup body 2. At the same time, the first pneumatic clamping claw 93 is controlled to relax the clamping claw, and the power output end is extended by the linear drive cylinder 96 to reset it. At the same time, the second pneumatic clamping claw 94 is reset to be able to clamp the magnetically attracted cup body 2 around. Secondly, the surface of the cup body 2 is visually inspected by the CCD camera 7 arranged on the side and bottom of the inspection platform, and the shooting picture is transmitted to the visual inspection system for analysis of the shooting result. At the same time, the second servo motor 810 can drive the magnetic support claw 82 to rotate circumferentially through the driving gear 811 and the driven gear ring 89, and synchronously drive the magnetically attracted cup body 2 to rotate, so as to continuously and uninterruptedly perform a comprehensive inspection on the surface of the cup body 2 to ensure the inspection accuracy; Finally, after the inspection is completed, the second pneumatic clamping claw 94 is used to clamp the inspected cup body 2, and at the same time, the power output end of the push cylinder 87 is retracted to pull the magnetic support claw 82 out of the cup body 2. The first pneumatic clamping claw 93 on the other side clamps the uninspected cup body 2 transported by the conveyor line 10, and then the power output end of the linear drive cylinder 96 is retracted. The two cup bodies 2 complete the displacement synchronously, and the inspected ones are transported to the sorting line 11 for sorting, and the uninspected ones are repeated for the above steps, and the inspection of one cup body 2 after another is completed over and over again.

[0054] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
