Description

Technical Field

[0001] This invention relates to the field of lamp inspection equipment technology, specifically a lamp inspection mechanism for blow molding machines with classification function. Background Technology

[0002] The light inspection mechanism is a device used to inspect the quality of blow-molded bottles. When a bottle arrives at the inspection station, backlight and bottom light sources are activated according to a preset pattern to illuminate the bottle, making internal and surface defects clearly visible. The acquired images are transmitted to an image processing and analysis system, which uses software algorithms to process and analyze the images, identifying various potential defects in the bottle. The output end of the electric gripper may accumulate dust or debris from the bottle during gripping, especially when the bottle is heavy. The electric gripper exerts a strong gripping force, making the output end prone to debris accumulation. Therefore, the output end of the electric gripper needs frequent cleaning to maintain high friction and improve the gripping effect on the bottle.

The first drive mechanism drives the first turntable, which is mounted on the connecting shaft, to rotate. The second drive mechanism drives the second turntable to rotate synchronously with the first turntable. The second turntable and the first turntable are coaxially connected via the connecting shaft. The first turntable is mounted on the worktable, and the second drive mechanism is mounted on the frame. The first turntable is equipped with a bottle-spinning mechanism, and the second turntable is equipped with a bottle-pressing mechanism. The container to be inspected is placed between the bottle-spinning mechanism and the bottle-pressing rod. The first turntable is driven by the first drive mechanism, and the second turntable is driven by the second drive mechanism to rotate synchronously with the first turntable. The second drive mechanism is connected to the frame, and the first turntable is mounted on the worktable.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention uses a first stepper motor to drive a third gear to rotate, which in turn drives a second gear to rotate, which in turn drives a disc to rotate, which in turn drives a support frame to rotate, which in turn drives a rack to rotate, which in turn drives an extension rod and an auxiliary wheel to rotate. The auxiliary wheel rotates to the convex position of the cam, causing it to move away from the center of the disc. This movement of the auxiliary wheel away from the center of the disc drives the extension rod to move away from the center of the disc, which in turn drives the rack to move away from the center of the disc. The rack moves in the direction of the movement, which drives the first gear to rotate. The rotation of the first gear drives the rotating frame to rotate. The rotation of the disc drives the rotating frame to rotate. The rotation of the rotating frame drives the C-shaped arc plate to rotate. The C-shaped arc plate rotates and contacts the first micro switch, which triggers the first micro switch. The first micro switch transmits an electrical signal to the external controller. The external controller controls the electric gripper to perform clamping. The rotation of the rotating frame drives the electric gripper to rotate. The electric gripper clamps the bottle containing the solution conveyed by the feeding mechanism. The rotation of the electric gripper causes the bottle containing the solution to rotate, which is beneficial for continuous clamping and detection of rotated bottles. After the detection is completed, the bottle automatically rotates back to its initial state. 2. The defective bottle is detected by a camera, and the information is transmitted to an external controller. The external controller then activates the sorting component to start sorting. The time it takes for the defective bottle to be removed from the unloading rotating frame is determined by the time the camera on the right detects the defective bottle. The sorting component is activated based on this fixed time difference to sort the defective bottle onto the second belt conveyor. The output shaft of the third stepper motor of the sorting component rotates, which drives the worm gear to rotate. The worm gear then drives the rotating arc frame to rotate. The rotating arc frame rotates to a preset position and stops. The defective bottle moves to the position on the first belt conveyor and, guided by the rotating arc frame, moves to the second belt conveyor. Then, the rotating arc frame returns to its initial state, thus completing the sorting of defective and qualified bottles. This facilitates the automatic classification of bottles after inspection.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] The present invention will be further described below with reference to embodiments.

[0026] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0027] Example 1: In some examples, please refer to Figures 1-14 A bottle blowing machine light inspection mechanism with classification function includes a frame 1. A feeding mechanism 2 for continuously feeding bottles is installed on the left side of the frame 1. A cleaning mechanism 5 for continuously cleaning the grippers is installed on the upper side of the feeding mechanism 2. A clamping and flipping mechanism 3 for continuously clamping and flipping the bottle is installed on the rear side of the frame 1.

[0029] The linkage flipping assembly includes: a support frame 31, a rack 32, a first gear 33, and a flipping frame 34. Multiple support frames 31 are located on the upper side of the frame 1. The rack 32 is slidably connected to the support frame 31. The first gear 33 is rotatably connected to the support frame 31 via a rotating shaft. The first gear 33 and the rack 32 mesh with each other. The flipping frame 34 is fixedly installed on the rotating shaft of the first gear 33. The clamping assembly includes: an electric gripper 35, which is fixedly installed on the flipping frame 34. Two support crossbars 36 are fixedly installed on the support frame 31. One end of the rack 32 is slidably connected to a limit rod 318. The end of the limit rod 318 away from the rack 32 is fixedly installed inside the support frame 31. A spring 319 is sleeved on the limit rod 318. One end of the spring 319 is in close contact with the rack 32, and the other end of the spring 319 is in close contact with the support frame 31.

[0030] The feeding mechanism 2 feeds the bottles filled with solution, the clamping and flipping mechanism 3 continuously clamps and flips the bottles after feeding, the light vision inspection mechanism 4 inspects the bottles filled with solution after clamping and flipping, and sorts and unloads them after inspection, and the cleaning mechanism 5 cleans the clamping and flipping mechanism 3.

[0031] The rack 32 of the clamping and flipping mechanism 3 moves, causing the first gear 33 to rotate. The rotation of the first gear 33 causes the flipping frame 34 to rotate. The rotation of the flipping frame 34 causes the electric gripper 35 to rotate. The electric gripper 35 clamps the bottle containing the solution conveyed by the feeding mechanism 2. The rotation of the electric gripper 35 causes the bottle containing the solution to flip. One of the support bars 36 supports the flipping plate in its initial state, and the other support bar 36 supports the electric gripper 35 in its flipped state.

[0032] The cam assembly includes: an electric slip ring 37, a disk 38, a cam 39, an extension rod 310, and an auxiliary wheel 311. The fixed end of the electric slip ring 37 is fixedly installed on the rear side of the frame 1. The disk 38 is fixedly installed on the rotating end of the electric slip ring 37. The cam 39 is fixedly installed on the frame 1. The extension rod 310 is fixedly installed on the end of the rack 32 away from the support frame 31. The auxiliary wheel 311 is rotatably connected to the end of the extension rod 310 away from the rack 32 via a rotating shaft. The auxiliary wheel 311 is in close contact with the cam 39. Multiple support frames 31 are evenly spaced in a circular array on the disk 38 with the center of the disk 38 as the center. The support frames 31 are fixedly installed on the disk 38. The electric gripper 35 is electrically connected to an external controller via the electric slip ring 37. The external controller can be set as an EPC-BS350 industrial control computer from Shenzhen Yanwei Technology Co., Ltd.

[0033] The rotation of the disc 38 of the cam assembly drives the support frame 31 to rotate, which in turn drives the rack 32 to rotate. The rack 32 then drives the extension rod 310 and the auxiliary wheel 311 to rotate. The auxiliary wheel 311 rotates to the protruding position of the cam 39, causing it to move away from the center of the disc 38. This movement of the auxiliary wheel 311 drives the extension rod 310 to move away from the center of the disc 38, which in turn drives the rack 32 to move away from the center of the disc 38. The movement of the rack 32 drives the first gear 33 to rotate. The cam 39 triggers a portion of the electric gripper 35 to flip, allowing the bottle containing the solution to be continuously gripped and flipped for testing. The bottle flipping tests the seal, and simultaneously inverts the liquid inside the bottle, causing impurities that are difficult to detect after settling at the bottom to fall to the bottle mouth. During this process, the impurities pass through the bottle body and are easily detected.

[0034] The triggering component includes: a circular frame 312, a C-shaped arc plate 313, and a first micro switch 314. The circular frame 312 is fixedly installed on the upper side of the cam 39, and the C-shaped arc plate 313 is fixedly installed on the outer side wall of the circular frame 312. The two ends of the C-shaped arc plate 313 are bent upwards. A first micro switch 314 is fixedly installed at one end of each support frame 31 near the center of the disk 38.

[0035] The rotation of the disc 38 causes the circular frame 312 to rotate, which in turn causes the C-shaped arc plate 313 to rotate. The C-shaped arc plate 313 rotates and contacts the first micro switch 314, triggering the first micro switch 314. The first micro switch 314 transmits an electrical signal to an external controller, which then controls the electric gripper 35 to perform clamping.

[0036] The cam assembly further includes a drive assembly, which is mounted on the lower side of the frame 1. The drive assembly includes a first stepper motor 315, a second gear 316, and a third gear 317. The first stepper motor 315 is fixedly mounted on the lower side of the frame 1, the second gear 316 is fixedly mounted on the lower side of the disc 38, and the third gear 317 is fixedly mounted on the output shaft of the first stepper motor 315.

[0037] The first step motor 315 of the drive assembly rotates, which drives the third gear 317 to rotate. The rotation of the third gear 317 drives the second gear 316 to rotate, and the rotation of the second gear 316 drives the disc 38 to rotate.

[0038] Example 2: In some embodiments, such as Figures 1-14 As shown, in a preferred embodiment of the present invention, the feeding mechanism 2 includes: a first belt conveyor 21, a bottle-separating screw 22, and a second stepper motor 23.

The first belt conveyor 21 transports the bottles containing solutions to the right until they reach the bottle-separating screw 22. The output shaft of the second stepper motor 23 rotates, driving the bottle-separating screw 22 to rotate. The rotation of the bottle-separating screw 22 drives the bottles containing solutions to continue to be transported to the right at equal intervals.

[0040] The feeding mechanism 2 further includes a feeding assembly, which is installed on the left side of the frame 1. The feeding assembly includes a first rotary table 24, a feeding rotary frame 25, a left support plate 26, and a limiting frame 27. The first rotary table 24 is fixedly installed on the left side of the frame 1. The feeding rotary frame 25 is fixedly installed at the output end of the first rotary table 24. The feeding rotary frame 25 has multiple first slots for accommodating bottles to be tested.

The limiting frame 27 is fixedly installed on the front side of the frame 1. The left side of the limiting frame 27 is close to the feeding rotary frame 25 to limit the bottles to be tested in the first slots of the feeding rotary frame 25 so that they do not move out of the first slots.

[0041] The bottle-separating screw 22 rotates, causing the bottles containing the solution to continue to be conveyed to the right at equal intervals. The bottles are then conveyed to the feeding rotating frame 25 of the feeding assembly. The output end of the first rotating worktable 24 rotates, causing the feeding rotating frame 25 to rotate. The first slot of the feeding rotating frame 25 moves to the position of the bottle containing the solution to accommodate it. The feeding rotating frame 25 rotates to continuously rotate and convey the bottle containing the solution to the position of the electric gripper 35, where it clamps the bottle.

The inspection cameras 41 can be set as TriSpector10003D smart cameras from Haoai Intelligent Technology Co., Ltd.

[0043] The light from the light panel 43 shines through the curved transparent plate 42 onto the inverted bottle containing the solution, and the detection camera 41 detects it and transmits the information to the external controller.

[0044] The light-based visual inspection mechanism 4 further includes a feeding assembly, which is installed on the right side of the frame 1. The feeding assembly includes a second rotating worktable 44, a feeding rotating frame 45, a right-side support plate 46, and a support piece 47. The second rotating worktable 44 is fixedly installed on the right side of the frame 1. The feeding rotating frame 45 is fixedly installed at the output end of the second rotating worktable 44.

The support piece 47 is fixedly installed on the right-side support plate 46. The right side of the limiting frame 27 is close to the feeding rotating frame 45 to limit the bottles after inspection in the second slots of the feeding rotating frame 45 so that they do not move out of the first slot.

[0045] After the bottle is inspected, it rotates back to its initial state and continues to rotate and be conveyed to the unloading rotating frame 45 of the unloading assembly. The electric gripper 35 opens, and the output end of the second rotating worktable 44 rotates, driving the unloading rotating frame 45 to rotate. The second slot of the unloading rotating frame 45 moves to the position of the bottle containing the solution to accommodate it. The unloading rotating frame 45 rotates to continuously rotate and convey the bottle containing the solution.

[0046] Example 3: In some embodiments, such as Figures 1-14As shown, in a preferred embodiment of the present invention, the feeding assembly further includes a material distribution assembly, which is installed on the right side of the frame 1. The material distribution assembly includes a vertical frame 48, a rotating arc frame 49, a worm gear 410, a third stepper motor 411, a worm 412, and a second belt conveyor 413. The vertical frame 48 is fixedly installed on the right side of the frame 1. The rotating arc frame 49 is rotatably connected to the right side of the vertical frame 48 via a rotating shaft. The worm gear 410 is fixedly installed on the rotating shaft of the rotating arc frame 49. The third stepper motor 411 is fixedly installed on the right side of the frame 1. Mounted on the vertical frame 48, the worm gear 412 is fixedly installed on the output shaft of the third stepper motor 411, and the worm gear 412 and the worm wheel 410 mesh with each other. The second belt conveyor 413 is fixedly installed on the right side of the frame 1. The front side of the second belt conveyor 413 and the rear side of the first belt conveyor 21 are in close contact, and the second belt conveyor 413 and the first belt conveyor 21 share a side baffle. The right side of the support plate 47 is in close contact with the left side of the second belt conveyor 413 to assist in supporting the bottles after inspection as they enter the second belt conveyor 413.

[0047] The detection camera 41 detects the defective bottle and transmits the information to the external controller. The external controller controls the material distribution component to start distributing the bottle. The time after the right-side detection camera 41 detects the defective bottle can be used to determine when the defective bottle moves out of the feeding rotating frame 45. The material distribution component is started by using this fixed time difference to distribute the defective bottle to the second belt conveyor 413.

[0048] The output shaft of the third stepper motor 411 of the sorting component rotates, driving the worm gear 412 to rotate. The rotation of the worm gear 412 drives the worm wheel 410 to rotate, and the rotation of the worm wheel 410 drives the rotating arc frame 49 to rotate. After the rotating arc frame 49 rotates to the preset position, it stops. The defective bottles move to the position of the first belt conveyor 21 and, guided by the rotating arc frame 49, move to the second belt conveyor 413. Then, the rotating arc frame 49 returns to the initial state, thus completing the sorting of defective and qualified bottles.

[0049] The cleaning mechanism 5 includes: an air nozzle 51, a funnel 52, an extension tube 53, and a second micro switch 54. The air nozzle 51 is fixedly mounted on the limiting frame 27 by a bracket. The funnel 52 is fixedly mounted on the middle side of the limiting frame 27. The extension tube 53 is fixedly mounted on the lower side of the funnel 52. The second micro switch 54 is fixedly mounted on the bracket of the air nozzle 51. The air nozzle 51 is connected to an external air supply device, and the extension tube 53 is connected to an external vacuuming device.

[0050] The rotation of disc 38 drives the support frame 31 to rotate. The rotation of support frame 31 contacts the second micro switch 54, which transmits an electrical signal to the external controller. The external controller controls the output ends of the external air supply equipment and the external vacuum cleaner to open, so that the air nozzle 51 sprays gas onto the electric gripper 35 to clean the output end of the electric gripper 35. The output end of the electric gripper 35 may be contaminated with dust or debris from the bottle. The bottle contains a solution, making it relatively heavy. Therefore, the output end of the electric gripper 35 needs to be cleaned frequently to maintain high friction and improve the gripping effect on the bottle. Most of the cleaned debris falls into the funnel 52, and the external vacuum cleaner starts to suck away the debris in the funnel 52.

[0051] The first micro switch 314, the first stepper motor 315, the first belt conveyor 21, the second stepper motor 23, the first rotary table 24, the detection camera 41, the second rotary table 44, the third stepper motor 411, the second belt conveyor 413, and the second micro switch 54 are all electrically connected to an external controller.
