Description

Technical Field

[0001] This utility model relates to the field of glass production technology, and in particular to a device for screening fine cracks at the bottom of bottles. Background Technology

[0002] Glass is an amorphous inorganic non-metallic material, generally made from a variety of inorganic minerals as the main raw materials and a small amount of auxiliary raw materials. It is widely used in buildings for wind insulation and light transmission. It is a mixture. After the glass is produced, the glass surface needs to be inspected for cracks. The specific operation is to apply a flaw detector to the glass surface, wipe it off after a period of time, and then apply a developer to check whether there are any scratches on the glass surface.

[0003] A search of existing technology revealed a device for detecting glass cracks, with publication number CN216208694U. This device has multiple sets of rubber suction cups installed on its slider. By stretching the slider, the bottom area of ​​the glass mounting plate is increased or decreased, achieving a stable fixation effect for glass of various sizes. The use of rubber suction cups further enhances the stability of the glass to be tested. However, during the testing operation, the device requires placing and testing each bottle individually, followed by removal and replacement, which reduces testing efficiency, delays the work process, and affects work productivity. Utility Model Content

[0004] Therefore, it is necessary to address the issue that the process of placing and replacing bottles one by one during inspection can lead to decreased inspection efficiency and delays in the work process. This necessitates providing a bottle bottom fine crack screening device, comprising: a mounting body, on one side of which a first servo motor is fixedly connected; a screening mechanism, installed inside the mounting body, with its surface connected to the output shaft of the first servo motor and extending to the side of the mounting body near the first servo motor; a detection component, installed on the side of the mounting body away from the first servo motor; and a sorting component, connected to the end of the mounting body near the first servo motor. The screening mechanism includes two rotating rollers rotatably connected inside the mounting body, one end of each roller fixedly connected to the output shaft of the first servo motor. A conveyor steel belt is fitted onto the surface of the two rollers, and multiple positioning components are fixedly connected to the surface of the conveyor steel belt. An abutment component is provided on the side of the conveyor steel belt near the first servo motor, and this abutment component is installed on one side of the mounting body. Adjust the conveyor belt speed to 1.2m / s to ensure that the bottle spacing is ≥150mm.

[0005] In one embodiment, the positioning component includes a connecting seat fixedly connected to the surface of the conveyor belt, a positioning arc plate fixedly connected to the inner bottom wall of the connecting seat, two side rubber plates fixedly connected to the upper end of the positioning arc plate, a stop block provided between the two side rubber plates, a notch opened at the end of the positioning arc plate near the first servo motor, and the stop block fixedly connected to the inner bottom wall of the positioning arc plate near the notch.

[0006] In one embodiment, the contact assembly includes a drive housing fixedly connected to one side of the mounting body. A controller is fixedly connected to the side of the drive housing, and a three-jaw chuck is rotatably connected to the upper end of the drive housing. A support frame fixedly connected to the upper end of the drive housing is sleeved on the outer side of the three-jaw chuck. A positioning ring is fixedly connected to the end of the support frame away from the drive housing, and a supplementary lighting ring is fixedly connected inside the positioning ring. The central axis of the chuck forms a 45-degree angle with the horizontal plane. The contact assembly uses an SMCMHT9-16D triple clamping unit, with an adjustable clamping force range of 5-15N. The standard clamping force for a 500ml bottle is set to 8N, depending on the bottle type.

[0007] In one embodiment, the detection component includes a support frame fixedly connected to the side of the mounting body away from the first servo motor. A connecting arm is fixedly connected to the side of the support frame near the mounting body. A multispectral camera is embedded in the end of the connecting arm away from the support frame. Multiple industrial cameras are arranged on the outside of the multispectral camera. A ring light source is fixedly connected to the surface of the connecting arm near the industrial cameras. A second infrared transceiver sensor is fixedly connected to the surface of the support frame at the lower end of the connecting arm. The ring light source contains multiple sets of LED ring light sources with different wavelengths: 365nm, 850nm, and 1450nm respectively. After the three-jaw chuck clamps the bottle mouth, the stepper motor drives the bottle to rotate one revolution. The industrial camera captures 12 frames of images of the bottle bottom from different angles. The key component, the LED ring light source, uses Osram SFH 4735 series infrared LEDs. The industrial camera is a Basler ace acA2000-165um model, equipped with a 25mm fixed-focus lens. The LED light source can be replaced with a xenon flash system, and the camera can be upgraded to a polarized light sensitive model to enhance crack contrast. The specific adjustments can be made according to the actual situation.

[0008] In one embodiment, the sorting assembly includes a guide frame fixedly connected to the mounting body near the end of a first servo motor. An electric push rod is fixedly connected to the side of the guide frame near the detection assembly, with its telescopic end extending into the interior of the guide frame. A second servo motor is fixedly connected to the other side of the guide frame, and a rotating shaft is fixedly connected to the output shaft of the second servo motor. The rotating shaft is rotatably connected to the inner wall of the guide frame. A third infrared receiving sensor is provided on the inner wall of the sorting assembly to identify the position of the bottle inside the guide frame.

[0009] In one embodiment, a connecting frame is fixedly connected to one side of the support frame, the connecting frame is fixedly connected to the surface of the positioning ring, and a plurality of first infrared transceiver sensors are embedded in the lower end of the connecting frame.

[0010] In one embodiment, a central partition is fixedly connected to the inner bottom wall of the guide frame, and arc-shaped toothed rubber strips are provided on both sides of the central partition. The lower end of the arc-shaped toothed rubber strips extends into the interior of the guide frame and is fixedly connected to a connecting plate, which is fixedly connected to the surface of the rotating shaft.

[0011] Beneficial effects

[0012] The aforementioned bottle bottom fine crack screening device uses a screening mechanism that, under the contact action of the positioning ring surface, pushes the bottle mouth downwards. At this time, the bottle body, under the action of the support frame, forms a lever effect to lift the bottle bottom, causing the bottle body to tilt and form an overall shape. It can be directly used with the detection component to perform detection without detaching from the conveyor belt. After the detection is completed, it can continue to be conveyed, simplifying the steps in the detection operation and improving the detection efficiency.

[0013] The sorting components, in conjunction with the screening mechanism, properly classify the two bottles and the defective products. When the good products are conveyed into the guide rack by the positioning components, the connecting plate drives the arc-shaped toothed rubber strip to retract into the guide rack, allowing the good product bottles to be discharged to the outside. When the defective products move, the arc-shaped toothed rubber strip remains still, driving the electric push rod to push the bottle to the other side of the middle partition. Through different channels on both sides of the middle partition, the good products and the defective products are collected separately. Attached Figure Description

[0029] The following is combined Figures 1-7 This invention describes a bottle bottom fine crack screening device.

[0030] In one embodiment, a bottle bottom fine crack screening device includes: a mounting body 1, with a first servo motor 2 fixedly connected to one side of the mounting body 1; a screening mechanism 3, installed inside the mounting body 1, with the surface of the screening mechanism 3 connected to the output shaft of the first servo motor 2, and the surface of the screening mechanism 3 extending to the side of the mounting body 1 near the first servo motor 2; a detection component 4, installed on the side of the mounting body 1 away from the first servo motor 2; and a sorting component 5, connected to the end of the mounting body 1 near the first servo motor 2.

[0031] The screening mechanism 3 includes two rotating rollers 31 rotatably connected inside the mounting body 1. One end of the rotating roller 31 is fixedly connected to the output shaft of the first servo motor 2. A conveying steel belt 32 is sleeved on the surface of the two rotating rollers 31. Multiple positioning components 34 are fixedly connected to the surface of the conveying steel belt 32. An abutting component 33 is provided on the side of the conveying steel belt 32 near the first servo motor 2. The abutting component 33 is installed on one side of the mounting body 1.

[0032] like Figure 1-4 As shown, the positioning component 34 includes a connecting seat 341 fixedly connected to the surface of the conveyor steel belt 32. A positioning arc plate 342 is fixedly connected to the inner bottom wall of the connecting seat 341. Two side rubber plates 343 are fixedly connected to the upper end of the positioning arc plate 342. A stop block 344 is provided between the two side rubber plates 343. A notch is opened at the end of the positioning arc plate 342 near the first servo motor 2. The stop block 344 is fixedly connected to the inner bottom wall of the positioning arc plate 342 near the notch.

[0033] The contact component 33 includes a drive housing 331 fixedly connected to one side of the mounting body 1. A controller 332 is fixedly connected to the side of the drive housing 331. A three-jaw chuck 333 is rotatably connected to the upper end of the drive housing 331. A support frame 334 fixedly connected to the upper end of the drive housing 331 is sleeved on the outside of the three-jaw chuck 333. A positioning ring 337 is fixedly connected to the end of the support frame 334 away from the drive housing 331. A supplementary light ring 338 is fixedly connected inside the positioning ring 337. A connecting frame 335 is fixedly connected to one side of the support frame 334. The connecting frame 335 is fixedly connected to the surface of the positioning ring 337. A plurality of first infrared transceiver sensors 336 are embedded in the lower end of the connecting frame 335.

[0034] In this embodiment, the device drives one of the rotating rollers 31 to rotate by driving the first servo motor 2. At this time, the conveyor belt 32 is connected to the two rotating rollers 31, so that the two rotating rollers 31 rotate synchronously. When the conveyor belt 32 rotates, it drives the positioning component 34 to move synchronously, and drives the bottle body to move through the positioning arc plate 342.

[0035] When the bottle moves to the positioning ring 337, the bottle mouth will be pressed downward by the contact action of the positioning ring 337 surface. At this time, the bottle body forms a lever action under the action of the support frame 334 to lift the bottom of the bottle, so that the bottle body is tilted at a 45-degree angle. At the same time, the side rubber plates 343 on both sides keep the bottle body from shifting too much, so that the bottle mouth and the three-jaw chuck 333 are on the same axis, and the bottom of the bottle is facing the multispectral camera 45.

[0036] The controller 332 is electrically connected to the rotating roller 31 and the three-jaw chuck 333. The first infrared transceiver sensor 336 embedded in the connecting frame 335 detects that the bottle has reached the detection position. At this time, the rotating roller 31 stops rotating and the control contact component 33 clamps the bottle mouth and rotates it four times at a 90-degree angle to cooperate with the detection component 4 to perform the detection operation.

[0037] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, the detection component 4 includes a support frame 41 fixedly connected to the side of the mounting body 1 away from the first servo motor 2. A connecting arm 42 is fixedly connected to the side of the support frame 41 close to the mounting body 1. A multispectral camera 45 is embedded in the end of the connecting arm 42 away from the support frame 41. Multiple industrial cameras 44 are arranged on the outside of the multispectral camera 45. A ring light source 43 is fixedly connected to the surface of the connecting arm 42 close to the industrial camera 44. A second infrared transceiver sensor 46 is fixedly connected to the lower end of the connecting arm 42 on the surface of the support frame 41.

[0038] The sorting assembly 5 includes a guide frame 51 fixedly connected to the mounting body 1 near the end of the first servo motor 2. An electric push rod 55 is fixedly connected to one side of the guide frame 51 near the detection assembly 4. The telescopic end of the electric push rod 55 extends into the interior of the guide frame 51. A second servo motor 53 is fixedly connected to the other side of the guide frame 51. A rotating shaft 54 ​​is fixedly connected to the output shaft of the second servo motor 53. The rotating shaft 54 ​​is rotatably connected to the inner wall of the guide frame 51. A middle partition 52 is fixedly connected to the inner bottom wall of the guide frame 51. Arc-shaped toothed rubber strips 57 are provided on both sides of the middle partition 52. The lower end of the arc-shaped toothed rubber strips 57 extends into the interior of the guide frame 51 and is fixedly connected to a connecting plate 56. The connecting plate 56 is fixedly connected to the surface of the rotating shaft 54.

[0039] In this embodiment, when the device is working, the second infrared transceiver sensor 46 detects when the bottle reaches the detection position. The second infrared transceiver sensor 46 is electrically connected to the controller 332. The ring light source 43 will generate light of various different wavelengths, and multiple industrial cameras 44 will take pictures of the bottle bottom from different angles to check for cracks in the bottle bottom. After the pictures are taken, the images are identified and the signals are sent to the controller 332 for processing, which controls the electric push rod 55 to perform a pushing operation.

[0040] When a good product is conveyed into the guide rack 51 by the positioning component 34, it will be intercepted by the arc-shaped toothed rubber strip 57 inside the guide rack 51. Then, the second servo motor 53 drives the rotating shaft 54 ​​to deflect, causing the connecting plate 56 to move the arc-shaped toothed rubber strip 57 into the guide rack 51, so that the good product bottle is discharged to the outside. At the same time, when the defective product moves into the guide rack 51, the arc-shaped toothed rubber strip 57 remains silent and drives the electric push rod 55 to push the bottle to the inside of the arc-shaped toothed rubber strip 57 on the other side of the middle partition 52. Then the arc-shaped toothed rubber strip 57 retracts, discharging the defective product to the outside. Good products and defective products are collected separately through different channels on both sides of the middle partition 52.

[0041] Working principle: The conveyor belt 32 is connected to two rotating rollers 31, driving the first servo motor 2 to make the two rotating rollers 31 rotate synchronously. When the conveyor belt 32 rotates, it drives the positioning component 34 to move synchronously. When the bottle body is located inside the positioning arc plate 342 and moves to the positioning ring 337, the surface of the positioning ring 337 abuts against the bottle mouth downwards. The bottle body forms a lever effect on the support frame 334 to lift the bottom of the bottle. The side rubber plates 343 on both sides keep the bottle body from shifting too much. The control abutment component 33 clamps the bottle mouth. When the second infrared transceiver sensor 46 detects that the bottle body has reached the detection position, the second infrared transceiver sensor 46 is electrically connected to the controller 332. The ring light source 43 generates light of multiple wavelengths, and the industrial camera 44 takes pictures of the bottom of the bottle from different angles.

[0042] When a good product is conveyed into the guide rack 51 through the positioning component 34, it will be intercepted by the arc-shaped toothed rubber strip 57 inside the guide rack 51. The second servo motor 53 drives the rotating shaft 54 ​​to deflect, and the connecting plate 56 drives the arc-shaped toothed rubber strip 57 to retract into the guide rack 51, and the good product bottle is discharged to the outside. When a defective product moves into the guide rack 51, the arc-shaped toothed rubber strip 57 remains silent and drives the electric push rod 55 to push the bottle to the inside of the arc-shaped toothed rubber strip 57 on the other side of the middle partition 52. Then the arc-shaped toothed rubber strip 57 retracts and discharges the defective product to the outside. Different channels on both sides of the middle partition 52 collect good products and defective products separately.

[0043] It should be noted that the first servo motor 2, drive chassis 331, controller 332, first infrared transceiver sensor 336, supplementary aperture 338, positioning component 34, industrial camera 44, multispectral camera 45, second infrared transceiver sensor 46, electric actuator 55, and second servo motor 53 mentioned above are all devices with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the power supply for the first servo motor 2, drive chassis 331, controller 332, first infrared transceiver sensor 336, supplementary aperture 338, positioning component 34, industrial camera 44, multispectral camera 45, second infrared transceiver sensor 46, electric actuator 55, and second servo motor 53 can be powered by the built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
