Technical Field

[0001] The utility model relates to the technical field of thermos cup bottom film detection, in particular to a thermos cup bottom film detection device which can reduce the cost of supporting feeding equipment and is based on machine vision. Background Art

[0002] A thermos cup is a special container or bottle designed to maintain the temperature of a liquid. It is usually made of double or multi-layer materials and has heat-insulating properties. It is designed to keep the temperature of hot drinks (such as hot water, coffee, tea) or cold drinks (such as ice water, cold drinks) for a period of time to prevent temperature loss. During the production process of a thermos cup, the bottom of the cup and the cup body are usually laser welded together to achieve the effect of vacuum insulation. Therefore, the quality of the film at the bottom of the cup is closely related to the processing efficiency and quality of the thermos cup. Before use, the film needs to be inspected for appearance defects and defective films are removed to avoid poor welding effects of the thermos cup due to film defects, and the insulation effect of the thermos cup cannot meet industrial standards.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In order to further understand the content, features and effects of the present invention, the following embodiments are described in detail as follows:

[0035] See also Figure 1 , Figure 2 As shown in the figure, the embodiment of the utility model proposes a thermos cup film detection device, which includes a mounting base 1, and the mounting base 1 is provided with a front and back detection platform 2, a front and back detection mechanism 3, a film flipping mechanism 4, a quality inspection platform 5, a film transport mechanism 6, a side defect detection mechanism 7 and an NG barrel 8. Among them, Figure 4 As shown, the front and back detection mechanism 3 is located directly above the front and back detection platform 2. The front and back detection platform 2 is used to receive the thermos cup film to be inspected fed by the matching external loading equipment. The front and back detection mechanism 3 performs front and back detection and identification, front defect detection, and front getter quantity abnormality detection on the thermos cup film to be inspected fed to the front and back detection platform 2 based on machine vision recognition. The film flipping mechanism 4 is located on the rear side of the front and back detection platform 2. When the front and back detection mechanism 3 detects that the thermos cup film to be inspected on the front and back detection platform 2 is reversely discharged with the bottom (inner wall side) facing upward, the film flipping mechanism 4 executes the film rotation instruction, clamps the thermos cup film to be inspected placed in reverse on the front and back detection platform 2, and rotates it so that its front side (outer wall side) faces upward. As shown Figure 1 and Figure 2As shown, the NG barrel 8 is located in the same straight line direction as the quality inspection station 5 and the front and back inspection station 2, and the film transport mechanism 6 is located in the rear direction of the quality inspection station 5, the front and back inspection station 2 and the NG barrel 8, and is parallel to the straight line where the front and back inspection station 2, the quality inspection station 5 and the NG barrel 8 are located. The film transport mechanism 6 transfers the film of the thermos cup to the corresponding workstation according to the corresponding test results. After completing the front and back detection and identification, front defect detection and front getter quantity abnormality detection of the thermos cup film on the front and back inspection station 2, the film transport mechanism 6 executes the corresponding transport instructions according to the test results. Specifically, when the front defect and getter abnormality of the thermos cup film are detected on the front and back inspection station 2, the thermos cup film is regarded as an NG product, and the film transport mechanism 6 grabs the NG product and transports it to the NG barrel 8. When it is detected on the front and back inspection station 2 that there is no front defect and getter abnormality on the insulation cup bottom film, the insulation cup bottom film is qualified in the inspection items at the front and back inspection station 2. At this time, the insulation cup bottom film also needs to be inspected for side defects. The film transport mechanism 6 grabs the insulation cup bottom film that has passed the inspection process and transfers it to the quality inspection station 5, where the side defect inspection process of the insulation cup bottom film is completed. Specifically, the quality inspection station 5 is a 360° rotating inspection station. When the side defect detection mechanism 7 performs side defect detection on the insulation cup bottom film on the quality inspection station 5, the quality inspection station 5 drives the insulation cup bottom film on it to rotate at a certain angle. Specifically, as Figure 3 As shown, the side defect detection mechanism 7 is located directly behind the quality inspection platform 5. The side defect detection mechanism 7 completes the side defect detection of the thermos cup film based on machine vision recognition. During the detection process, the quality inspection platform 5 drives the thermos cup film to take pictures of it at a certain rotation angle to obtain its side profile information, and then completes the side defect detection of the thermos cup film through machine vision recognition. When it is detected that there is no defect on the side of the thermos cup film, the thermos cup film is considered to be a qualified product, and the film transport mechanism 6 grabs the qualified product and transfers it to the matching output conveyor belt for discharge. When it is detected that there is a defect on the side of the thermos cup film, the thermos cup film is considered to be an NG product, and the film transport mechanism 6 grabs the NG product and transfers it to the NG barrel 8.

[0036] Further, in an embodiment of the present utility model, if Figure 4 and Figure 5 As shown, the front and back inspection platform 2 includes a lower platform 21 and an upper platform 22 both of which have notches on the rear side, wherein the notch on the upper platform 22 is composed of a circular notch and a rectangular notch connecting the circular notch, and the notch on the lower platform 21 is composed of a rectangular notch. Figure 6 As shown, the rectangular notch on the lower platen 21 overlaps with the rectangular notch on the upper platen 22. Figure 5As shown, the upper platen 22 is fixed on the upper surface of the lower platen 21, and a film sensing sensor 23 is provided on the upper surface of the lower platen 21 in the notch of the upper platen 22. Specifically, the circular notch on the upper platen 22 faces the middle of the lower platen 21, and the film sensing sensor 23 is located in the circular notch. The film sensing sensor 23 is used to sense whether there is a thermos cup film in place on the front and back detection platform 2. In the embodiment of the utility model, the film sensing sensor 23 can be a non-contact sensor such as a proximity sensor, a photoelectric sensor, etc. The rear notches of the lower plate 21 and the upper plate 22, i.e., the rectangular notches that overlap each other, form a clamping claw placement position 24, which can be used to place the clamping claw of the film flipping mechanism 4. Since the clamping claw placement position 24 is a notch that passes through the upper plate 22 and the lower plate 21, the clamping claw of the film flipping mechanism 4 can easily and quickly grab the film of the thermos cup placed on the upper plate 22 from the clamping claw placement position 24. In order to conveniently flip the film of the thermos cup, such as Figure 5 As shown, the lower plate 21 is connected with a flipping and giving way mechanism 25 for driving the lower plate 21 and the upper plate 22 to move up and down in the vertical direction as a whole. When the thermos cup bottom film is to be turned straight, the clamping claws of the bottom film flipping mechanism 4 clamp the thermos cup bottom film, and then the flipping and giving way mechanism 25 drives the lower plate 21 and the upper plate 22 to move downward in the vertical direction as a whole to adjust a height, and then the flipping and giving way mechanism 25 rotates, driving the thermos cup bottom film to rotate 180°, thereby realizing its straightening. Since the flipping and giving way mechanism 25 has adjusted the lower plate 21 and the upper plate 22 as a whole downward by a height, the lower plate 21 and the upper plate 22 will not interfere with the rotating thermos cup bottom film.

[0037] Further, in an embodiment of the present utility model, if Figure 4 and Figure 5 As shown, the flipping mechanism 25 includes a positioning plate 251 located below the mounting substrate 1, wherein a through hole is opened in the middle of the positioning plate 251, and a connecting seat 252 spanning the through hole is fixed on the positioning plate 251, and the connecting seat 252 is fixed to the lower surface of the mounting substrate 1. Figure 5As shown, a vertically telescopic first guide rod cylinder 253 is fixed on the connecting seat 252, and the cylinder body of the first guide rod cylinder 253 passes through the through hole of the positioning plate 251 and is located in the space below the mounting base plate 1. The guide rod end of the first guide rod cylinder 253 is connected to the lower platen 21, and two opposite positioning guide rods 254 are movably provided on the mounting base plate 1 on both sides of the first guide rod cylinder 253. Specifically, a sliding sleeve is provided on the positioning guide rod 254, and the sliding sleeve is fixedly connected to the mounting base plate 1. The positioning guide rod 254 can move up and down in the sliding sleeve, and the upper end of the positioning guide rod 254 is connected to the lower platen 21, and the lower end is connected to the positioning plate 251. When it is necessary to perform a giving way action, the guide rod of the first guide rod cylinder 253 retracts, driving the lower platen 21 and the upper platen 22 to move downward in the vertical direction as a whole to adjust a height. During the downward movement, the positioning guide rods 254 on both sides stabilize the first guide rod cylinder 253 and the lower platen 21 and the upper platen 22 as a whole.

[0038] Further, in an embodiment of the present utility model, if Figure 4 and Figure 5 As shown, in order to make the film of the thermos cup centered at the circular notch of the upper plate 22, that is, directly above the film sensing sensor 23, opposite film centering mechanisms 26 are provided on both sides of the upper plate 22. When the film of the thermos cup is transported to the front and back detection platform 2 through the film transport mechanism 6, the film centering mechanism 26 adjusts the position of the film of the thermos cup located on the front and back detection platform 2, so that the film of the thermos cup is centered at the circular notch of the upper plate 22, which can facilitate the sensing of the film sensing sensor 23 and also make the film of the thermos cup face the image acquisition lens of the front and back detection mechanism 3 above.

[0039] Further, in an embodiment of the present utility model, if Figure 5 As shown, the film centering mechanism 26 includes a support seat 261, a support platform 2611, a second guide rod cylinder 262 and a "V"-shaped slider 263. Specifically, the support seat 261 is fixed on the mounting base 1, the support platform 2611 is fixed on the upper end of the support seat 261, the second guide rod cylinder 262 is fixed on the upper surface of the support platform 2611, and the "V"-shaped slider 263 is connected to the guide rod of the second guide rod cylinder 262. In order to make the "V"-shaped slider 263 slide and adjust more stably on the support platform 2611, the lower surface of the "V"-shaped slider 263 is slidably connected to the upper surface of the support platform 2611, specifically, a sliding guide structure in which a slide groove and a slide rail cooperate is adopted.

[0040] Further, in an embodiment of the present utility model, if Figure 4As shown, the front and back detection mechanism 3 includes a 3D depth camera 31 with a lens pointing vertically downward and facing the center of the front and back detection platform 2, and a ring light source 32 located between the front and back detection platform 2 and the 3D depth camera 31. Among them, a first column 11 is provided on the mounting base plate 1, a crank arm bracket 111 is provided on the top of the first column 11, a light source bracket is provided in the middle, the 3D depth camera 31 is fixed on the crank arm bracket 111, and the ring light source 32 is fixed on the light source bracket. The ring light source 32 uses a high-angle ring light, which can clearly highlight the texture and details of the object surface of the thermos cup bottom film, so that the detailed information that is conducive to the front and back detection is highlighted.

[0041] Further, in an embodiment of the present utility model, if Figure 7 As shown, the film flipping mechanism 4 includes a fixing frame 41 arranged on the mounting base plate 1, a rotating cylinder 42 fixed on the fixing frame 41, and a clamping claw cylinder 43 fixed on a rotating end cover 421 of the rotating cylinder 42. Among them, the end of the clamping claw cylinder 43 is provided with two clamping claws 44 that can be opened or clamped in the vertical direction. When the film is not clamped, the two clamping claws 44 are at a large opening angle, and do not interfere with the placement position of the thermos cup film on the upper platen 22. When the thermos cup film needs to be clamped, the two clamping claws 44 are relatively closed and clamped in the vertical direction under the drive of the clamping claw cylinder 43, so as to clamp the edge of the thermos cup film placed on the upper platen 22. Figure 7 The state shown in the figure is the state of clamping of the clamping jaws 44. In order to avoid damage to the bottom film of the thermos cup, the clamping surface of the clamping jaws 44 is provided with a silicone pad for buffering, which can avoid rigid contact with the bottom film of the thermos cup.

[0042] Further, in an embodiment of the present utility model, if Figure 8 , Fig. 9 and Fig.10 As shown, the quality inspection platform 5 includes a gear transmission seat 51, a turntable 52, a servo motor 53, a suction cup platform 54, a lower suction cup 55, a solenoid valve 56, a disc-shaped light source 57 and a transparent cover platform 58. Specifically, the gear transmission seat 51 is fixed on the mounting substrate 1, the turntable 52 is rotatably arranged on the gear transmission seat 51, and is fixedly connected to the gear ring in the gear transmission seat 51. The servo motor 53 meshes with the outer ring shaft teeth of the gear ring in the gear transmission seat 51 through the gear on the gear shaft, thereby driving the turntable 52 to rotate on the gear transmission seat 51. Figure 8As shown, a circular assembly opening is provided at the center of the turntable 52, and a cylindrical suction cup platform 54 passes through the circular assembly opening and protrudes from the upper surface of the turntable 52.

The opening of the lower suction cup 55 faces upward, and its plate body is fixed on the suction cup platform 54. The lower end of the suction cup platform 54 is provided with an electromagnetic valve 56 for controlling the lower suction cup 55. The electromagnetic valve 56 is located on one side of the lower surface of the mounting substrate 1, that is, in the space below the mounting substrate 1. In order to increase the stability of the electromagnetic valve 56, an electromagnetic valve bracket 15 is fixed on one side of the lower surface of the mounting substrate 1, and the bottom of the electromagnetic valve 56 is fixed on the electromagnetic valve bracket 15. A circular through hole matched with the suction cup platform 54 is provided at the center of the disc-shaped light source 57. The disc-shaped light source 57 is mounted on the suction cup platform 54 through the circular through hole. The two are connected in a relatively rotatable relationship, that is, the suction cup platform 54 remains stationary, and the disc-shaped light source 57 and the turntable 52 can rotate synchronously as a whole. A transparent cover platform 58 is provided on the disc-shaped light source 57.

The connecting arm slider 622 is fixedly connected to the double-station connecting arm 63. Under the vertical drive of the third guide rod cylinder 621, the connecting arm slider 622 and the double-station connecting arm 63 can be fine-tuned up and down as a whole in the vertical direction, so that the upper suction cup 64 can more accurately grasp and place the bottom film of the thermos cup.

When the longitudinal linear drive module 721 drives the vertical linear drive module 722 and the black-and-white industrial camera 71 to move and adjust in the longitudinal direction as a whole, the clearance opening 14 provides a movable space for the vertical linear drive module 722 to move in the longitudinal direction. At the same time, due to the setting of the clearance opening 14, the lower half of the vertical linear drive module 722 can be arranged on one side of the lower surface of the mounting substrate 1, that is, the space below the mounting substrate 1. This setting can also reduce the installation height of the two-axis adjustment component 72 on the mounting substrate 1, and also reduce the volume of the device.
