Description

Technical Field

[0001] This utility model relates to the field of industrial automation testing equipment technology, specifically to a device for detecting easily broken bottles. Background Technology

[0002] In the injection molding production of pharmaceutical easy-break bottles, the uniformity of wall thickness in all parts of the bottle is a key indicator affecting product quality. Traditional inspection methods mainly rely on manual visual inspection using a handheld high-powered flashlight. This method is not only inefficient but also has the following serious drawbacks: First, manual inspection is much slower than the production cycle of modern injection molding machines, creating a production bottleneck. The inspection time for a single part can be as long as 10-15 seconds. Furthermore, as working hours increase, operators experience visual fatigue, leading to a significant increase in both missed and false positive rates. Statistics show that after two hours of continuous work, the false positive rate for manual inspection can exceed 5%.

[0003] Secondly, while some existing automated testing equipment has improved efficiency to some extent, it still has significant shortcomings: 1) The detection function is limited. Most devices only detect the bottle body or bottom, and cannot achieve comprehensive and simultaneous detection of the bottle head, neck, body and bottom. 2) Multi-angle detection is not possible; due to the complex shape of certain parts of the bottle, shadows or refractions are easily generated, resulting in blind spots in the detection. 3) The light source is fixed and the illumination angle cannot be adjusted according to the bottle's posture, which affects the image acquisition quality.

[0004] These technical deficiencies severely restrict the improvement of quality control levels in the pharmaceutical industry. Therefore, developing a new type of testing device that can comprehensively overcome these deficiencies is of significant practical importance. Utility Model Content

Detailed Implementation

[0020] The following is in conjunction with the appendix Figure 1-8 The present invention will be described in further detail below.

[0021] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0022] This embodiment relates to a device for detecting easily broken bottles, including: a frame 1, which is welded from high-quality carbon structural steel, has high overall rigidity, and its first-order natural frequency reaches 85Hz, effectively avoiding common vibration source frequencies. A lifting bracket 10 and a control module 14 are installed on the frame 1. The lifting bracket 10 can be a manual lifting bracket or an electric lifting bracket, which can be selected according to the actual situation. The control module 14 is preferably an industrial control computer. A camera 11 and a ring-shaped supplementary light device 12 are rotatably connected to the lifting bracket 10. The camera 11 is located above the ring-shaped supplementary light device 12 and is coaxially distributed with it. The ring-shaped supplementary light device 12 is a ring-shaped RGBW four-color LED light, and the color temperature can be adjusted through the control module 14 or by setting a control button (not shown). A drive assembly is installed on the frame 1. The drive assembly includes a lateral movement mechanism installed on the frame 1 and a rotation mechanism installed on the lateral movement mechanism. The lateral movement mechanism is used to drive the easy-break bottle to move along the length and width of the frame 1. The rotation mechanism is used to drive the easy-break bottle to rotate 360° in the horizontal plane and level in the vertical plane. A tray 8 is installed on the rotation mechanism. A backlight 18 is installed on the tray 8. A light shield 17 is installed on the backlight 18. Several evenly distributed detection holes 19 are opened on the light shield 17.

[0023] In this embodiment, the control module 14 is electrically connected to the electrical components in the device. The control module 14 is used to control the opening and closing of the electrical components and to receive images captured by the camera 11 and analyze the thickness of the fragile bottle in the images. The fragile bottle includes a bottle body and a cap on the bottle body. When the thickness of the fragile bottle needs to be detected, the cap and bottle body can be placed on the backlight 18, or a clamp or vacuum adsorption device can be set to position the cap and bottle body on the backlight 18 to ensure the stability of the cap and bottle body. The cap and bottle body are then aligned with the detection hole 19. The control module 14 starts the lateral movement mechanism to move the bottle laterally. The moving mechanism drives the rotating mechanism, tray 8, backlight 18, and easy-break bottle to move along the length and width of the frame 1, so that the easy-break bottle is close to the camera 11. Then the lateral movement mechanism is closed, the lifting bracket 10 is adjusted so that the camera 11 is aligned with the top of the bottle, the backlight 18 and the ring light device 12 are turned on, the backlight 18 emits light and shines on the bottle through the detection hole 19, and the ring light device 12 can provide supplementary light to the camera 11, which can eliminate the shadow produced by the camera 11 when shooting, and improve the accuracy of detection. When the color temperature of the ring light device 12 needs to be adjusted, the worker can operate the control module 14 to adjust it. After the top of the bottle has been inspected, the bottle can be inverted, and an image of the bottom of the bottle can be taken. Afterwards, the bottle is placed upright on the backlight 18, and the lateral movement mechanism is driven to move the fragile bottle away from the camera 11. Then, the lifting bracket 10 can be adjusted downwards, and the camera 11 is rotated so that it faces the side of the bottle (including the neck and body). The lateral movement mechanism is then driven to bring the bottle closer to the camera 11. After adjustment, the lateral movement mechanism is turned off. By adjusting the height of the lifting bracket 10, the camera 11 can capture multiple points on the vertical side of the bottle. The bottle can also be rotated horizontally by manipulating the rotation mechanism, and the camera 11 can capture multiple points on the circumferential side of the bottle. When certain parts of the bottle are prone to shadows or refraction due to their complex shape, such as the neck with multiple convex and concave structures, the worker can rotate the camera 11, and the ring supplementary lighting device 12 will also rotate with it, enabling multi-angle detection and effectively avoiding blind spots. The images captured by the camera 11 are transmitted to the control module 14, which can compare these images with standard images to accurately determine whether the thickness of different parts of the bottle is consistent. The lid can be tested using the method described above, which will not be repeated here.

[0024] The setup in this application not only enables all-round synchronous detection of the bottle head, neck, body, and bottom, but also allows for multi-angle detection through rotating the camera 11. This avoids blind spots caused by shadows or refractions due to the complex shape of certain parts of the bottle. Furthermore, the illumination angle of the ring-shaped supplementary lighting device 12 can be adjusted according to the bottle's posture, thus improving the image acquisition quality.

[0025] like Figure 7-8 As shown, a rotating head 16 is mounted on the lifting bracket 10, and a mounting plate 15 is mounted on the rotating head 16. The camera 11 and the ring light device 12 can both be detachably connected to the mounting plate 15.

[0026] In this embodiment, the mounting plate 15 is used to mount and fix the camera 11 and the ring light device 12. Rotating the camera 11 or the ring light device 12 will cause the mounting plate 15 to rotate inside the rotating head 16. The rotation range of the rotating head 16 is 0-45°, that is, it rotates from the horizontal plane to the vertical plane.

[0027] like Figure 1-2 As shown, the transverse motion mechanism includes a first electric guide rail 2 and a second electric guide rail 3. The first electric guide rail 2 is mounted on the frame 1 and moves along the length of the frame 1. The second electric guide rail 3 is mounted on the first electric guide rail 2 and moves along the width of the frame 1. The rotation mechanism is mounted on the second electric guide rail 3.

[0028] In another embodiment, when the control module 14 activates the first electric guide rail 2 and the second electric guide rail 3, the first electric guide rail 2 will drive the second electric guide rail 3, the rotating mechanism, the backlight 18 and the easy-break bottle to move along the length direction of the frame 1, and the second electric guide rail 3 will drive the rotating mechanism, the backlight 18 and the easy-break bottle to move along the width direction of the frame 1, so as to facilitate the adjustment of the position of the easy-break bottle.

[0029] like Figure 1-2 As shown, the rotating mechanism includes a mounting base 4, a rotating platform 5, an adjusting plate 6, and a rotating component. The mounting base 4 is mounted on the second electric guide rail 3. The rotating platform 5 is rotatably connected to the mounting base 4 and rotates in a horizontal plane. The adjusting plate 6 is mounted above the rotating platform 5. The rotating component is mounted on the rotating platform 5 and is connected to the adjusting plate 6 via a transmission connection. The adjusting plate 6 rotates in a vertical plane, and an electric cylinder 20 is installed between the adjusting plate 6 and the tray 8. The rotating component includes a motor 7 and a worm gear assembly. Both the motor 7 and the worm gear assembly (not shown) are mounted on the rotating platform 5. The output end of the motor 7 is fixedly connected to one end of the worm gear assembly, and the movable end of the worm gear assembly is connected to the adjusting plate 6 via a transmission connection. A level 9 is mounted on the tray 8.

[0030] In this embodiment, rotating the rotary table 5 can drive the adjusting plate 6, electric cylinder 20, tray 8, backlight 18, and easy-break bottle to rotate in the horizontal plane. If the adjusting plate 6 needs to be leveled, the motor 7 is started, and the motor 7 will drive the worm gear assembly to rotate in the vertical plane. It should be noted that the angle range of the adjusting plate 6 is ±15°. The level 9 on the tray 8 can be used to measure whether the adjusting plate 6 is level, which is beneficial for more accurate detection of easy-break bottles.

[0031] like Figure 1-2As shown, an electric robotic arm 13 is installed on the frame 1. The electric robotic arm 13 is used to grasp the product to be inspected.

[0032] In this embodiment, the electric robotic arm 13 can be used to place the fragile bottle to be tested on the backlight 18 or remove it from the backlight 18, reducing the workload of workers.

[0033] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
