Description

Technical Field

[0001] The utility model relates to the field of industrial automation detection, in particular to automatic visual bottle inspection equipment. Background Art

[0002] Industrial vision, also known as machine vision, is a key technology in industrial automation. It uses optical, non-contact sensing devices to capture images and convert them into digital signals, enabling object identification, measurement, location, and detection. Industrial vision systems are widely used in automated production lines to improve efficiency, ensure product quality, and reduce costs. They also play a vital role in hazardous environments unsuitable for manual labor or where human vision is insufficient.

[0003] Existing visual bottle inspection equipment typically uses the following process: a bottle passes in front of a scanner, which captures the bottle's image and processes and analyzes it. The inspection results are then transmitted to a control system. When the bottle continues to move and reaches a designated position, the control system uses the results to decide whether to allow the bottle to pass or eject it from the conveyor. For example, a medicine bottle inspection machine not only detects cosmetic defects but also connects to a bottle unscrambler and case packer, enabling automated sorting and case packing throughout the entire process. This automated inspection method significantly improves inspection efficiency and accuracy, reduces manual intervention, and lowers defective product rates.

[0004] Because image capture is typically performed using single or multiple fixed-position scanners, certain parts of the bottle, such as the edges, bottom, or defects at specific angles, may not be accurately captured due to limited scanning angles or lighting conditions. Furthermore, due to the scanner's field of view and resolution limitations, visual inspection can have a certain rate of misjudgment when detecting defects on tiny or complex surfaces. This is especially true when bottles are moving rapidly on conveyor belts, requiring extremely fast image capture and processing times, further increasing the difficulty of detection. Utility Model Content

[0005] In order to overcome the disadvantage of relatively high detection difficulty, the utility model provides an automatic visual bottle inspection device that is convenient for detection.

[0006] The automatic visual bottle inspection equipment includes a load-bearing frame, a baffle, a visual camera, a pusher, a drive roller, a conveyor belt, a drive motor, a support frame and a rotating mechanism. Baffles are connected to the front and rear sides of the top of the load-bearing frame, and a drive motor is installed on the baffle. A drive roller is rotatably connected between the two baffles. The conveyor belt is sleeved on the drive roller, and one of the drive rollers is connected to the output shaft of the drive motor. The rear baffle is connected to the support frame, and a visual camera is installed on the support frame for scanning and inspecting bottles. A pusher is installed on the visual camera for pushing out the inspected bottles. The visual camera and the pusher are connected by wire. There is an opening in the middle of the front baffle, and a rotating mechanism is provided on the conveyor belt for placing and rotating the inspected bottles.

[0007] In one embodiment, the rotating mechanism includes a fixed ring, a rotating shaft, a mounting plate, a rotating motor, a clamping rod and a tray. A mounting plate is connected between the two baffles, and a rotating motor is installed at the bottom of the mounting plate. The mounting plate and the rotating motor are both located between the conveyor belts. The output shaft of the rotating motor passes through the mounting plate and is connected to the clamping rod. The front and rear sides of the fixed ring are connected to the rotating shaft, and the rotating shaft is connected to the conveyor belt. One side of the tray is rotatably connected to the fixed ring, and a clamping slot is opened on the other side of the tray. The clamping slot cooperates with the clamping rod for transmission. The tray is used to place the test bottles.

[0008] In one embodiment, a positioning ring is further included. The top of the tray is connected with the positioning ring to stabilize the test bottle.

[0009] In one embodiment, the portion of the tray where the card slot is opened is rounded to form a connecting opening.

[0010] In one embodiment, a defective product collection box is further included, and the defective product collection box is placed at the bottom of the load-bearing frame.

[0011] In one embodiment, an identification plate is further included, and the identification plate is connected to the baffle.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By driving the inspection bottle to rotate through the rotating mechanism and coordinating with the visual camera's scanning, a 360-degree all-round inspection of the inspection bottle is achieved, which can more comprehensively capture all angles and details of the bottle, thereby improving the accuracy of the inspection and reducing the difficulty of the visual camera's inspection.

DETAILED DESCRIPTION

[0020] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] Example: Automatic visual bottle inspection equipment, such as Figure 1-Figure 5 As shown, it includes a load-bearing frame 1, a baffle 2, a visual camera 3, a pusher 4, a driving roller 5, a conveyor belt 6, a driving motor 7, a support frame 8 and a rotating mechanism. The baffle 2 is connected to the front and rear sides of the top of the load-bearing frame 1, and the driving motor 7 is installed on the baffle 2. The driving roller 5 is rotatably connected between the two baffles 2, and the conveyor belt 6 is sleeved on the driving roller 5, one of the driving rollers 5 is connected to the output shaft of the driving motor 7, the rear baffle 2 is connected to the support frame 8, and the support frame 8 is equipped with a visual camera 3 for scanning and inspecting bottles 101. The visual camera 3 is equipped with a pusher 4 for pushing out the inspection bottles 101. The visual camera 3 is connected to the pusher 4 through a wired connection, and can convert the inspection results into control signals and send them to the pusher 4 in real time to control its operation. There is an opening in the middle of the front baffle 2, which is located directly in front of the pusher 4. A rotating mechanism is provided on the conveyor belt 6 for placing and rotating the inspection bottles 101.

[0022] like Figure 4 and Figure 5 As shown, the rotating mechanism includes a fixing ring 9, a rotating shaft 10, a mounting plate 11, a rotating motor 12, a clamping rod 13 and a tray 14. The mounting plate 11 is connected between the two baffles 2. The rotating motor 12 is installed at the bottom of the mounting plate 11. The mounting plate 11 and the rotating motor 12 are both located between the conveyor belts 6. The output shaft of the rotating motor 12 passes through the mounting plate 11 and is connected to the clamping rod 13. A controller is installed on the baffle 2. The controller is connected to the visual camera 3 and the drive motor 7 through a wired connection for receiving and sending signals to achieve coordinated work of the equipment, and the controller can run the set program The front and rear sides of the fixing ring 9 are connected to the rotating shaft 10, the rotating shaft 10 is connected to the conveyor belt 6, one side of the tray 14 is rotatably connected to the fixing ring 9, and the other side of the tray 14 is provided with a slot 15, the slot 15 and the card rod 13 are transmission-coordinated, the tray 14 is used to place the test bottle 101, and the portion of the tray 14 with the slot 15 is rounded to form a connecting opening 17. By rounding the ends of the slot 15 on the pallet, the tray 14 moves with the conveyor belt 6, and the slot 15 cooperates with the card rod 13 more smoothly, ensuring that the card rod 13 can be accurately inserted into the slot 15.

[0023] The detection bottle 101 is placed on the tray 14 through a robotic arm or intermittent conveying component, the driving motor 7 and the rotating motor 12 are turned on, and the working is coordinated through the controller. The driving motor 7 drives the driving roller 5 to rotate, thereby driving the conveyor belt 6 to rotate and conveying the detection bottle 101 backward. When the detection bottle 101 reaches the middle part of the baffle 2, the card slot 15 at the bottom of the tray 14 docks with the card rod 13, and the card rod 13 is inserted into the card slot 15. At this time, the driving motor 7 stops, and the rotating motor 12 drives the card rod 13 to rotate 360 degrees. The card rod 13 drives the tray 14 to rotate through the card slot 15, thereby driving the detection bottle 101 to rotate, and the turned-on visual camera 3 performs 360-degree viewing of the detection bottle 101. The visual inspection is performed by the camera 3, and the result of the visual inspection is converted into a control signal, which is sent to the pusher 4. The pusher 4 decides whether to start according to the received signal. If the inspection bottle 101 has defects, the visual camera 3 sends a signal, and the pusher 4 starts according to the signal to push the inspection bottle 101 out of the conveyor belt 6. At the same time, after the visual inspection is completed, a signal is sent to the controller. The controller controls the driving motor 7 and the rotating motor 12 to start and stop repeatedly according to the program, and cooperates with the visual camera 3 to achieve the effect of intermittent inspection. When the tray 14 moves with the conveyor belt 6, it is connected to the conveyor belt 6 through the rotating shafts 10 at both ends of the fixed ring 9. After the inspection bottle 101 with good quality passes through the conveyor belt 6, it proceeds to the next production step.

[0024] like Figure 1 and Figure 4 As shown, a positioning ring 16 is also included. The top of the tray 14 is connected with the positioning ring 16 to stabilize the test bottle 101.

[0025] When the detection bottle 101 is placed, the bottom of the detection bottle 101 contacts the positioning ring 16, so that the detection bottle 101 is more stable when moving with the conveyor belt 6 and will not slide on the push plate to affect the detection.

[0026] like Figure 1 As shown, a defective product collection box 18 is also included. The defective product collection box 18 is placed at the bottom of the load-bearing frame 1 and is used to collect defective products.

[0027] like Figure 1 As shown, an identification plate 19 is also included, and the baffle 2 is connected to the identification plate 19 .

[0028] The sign 19 marks the defective product exit to remind the staff that the test bottle 101 will fly out from here and they should not block the opening of the baffle 2.

[0029] During operation, the test bottle 101 is first placed on the tray 14 of the rotating mechanism by a robotic arm or an intermittent conveying component. The positioning ring 16 on the tray 14 ensures the stability of the test bottle 101 during movement to prevent sliding from affecting the test results. The tray 14 is connected to the conveyor belt 6 through the rotating shafts 10 at both ends of the fixed ring 9 to ensure stable movement. Subsequently, the drive motor 7 is started to drive the drive roller 5 to rotate, thereby driving the conveyor belt 6 to transport the test bottle 101 backward. When the test bottle 101 moves to the middle of the baffle 2, the slot 15 at the bottom of the tray 14 docks with the card rod 13 driven by the rotating motor 12, and the card rod 13 is inserted into the slot 15. The two ends of the slot 15 are rounded to ensure smooth cooperation with the card rod 13. At this time, the drive motor 7 stops working, and the rotating motor 12 drives the card rod 13 to rotate 360 degrees, thereby driving the tray 14 and the test bottle 101 to rotate through the slot 15. , achieving 360-degree inspection. During this process, the visual camera 3 is turned on to perform a full-scale visual scan of the rotating inspection bottle 101, and converts the inspection result into a control signal and sends it to the pusher 4 immediately. If the inspection bottle 101 is defective, the pusher 4 will start immediately according to the received signal and push the inspection bottle 101 out of the opening in the middle of the front baffle 2 onto the conveyor belt 6. The defective product collection box 18 at the bottom of the load-bearing frame 1 is responsible for collecting the pushed out defective products for subsequent processing. At the same time, the visual camera 3 sends a signal to the controller, and the controller controls the start and stop of the drive motor 7 and the rotating motor 12 according to the preset program to achieve intermittent inspection, ensuring that each inspection bottle 101 can be carefully inspected. The inspection bottles 101 with good quality continue to move with the conveyor belt 6 and enter the next production step. The identification plate 19 marks the defective product outlet to remind staff to pay attention to safety.
