Technical Field

[0001] This utility model relates to the field of glue bubble detection, and in particular to a glue bubble detection and degreasing device. Background Technology

[0002] Air bubbles often get mixed into the glue during dispensing machine operation. These bubbles affect the quality and effect of dispensing, leading to product defects. Traditional detection methods mostly rely on manual visual inspection, which is not only inefficient but also prone to missed or false detections due to human error. Especially on large-scale production lines, this method is insufficient to meet the demands of efficient and accurate production. Therefore, developing a device that can automatically, quickly, and accurately detect and remove air bubbles in glue is of great significance for improving dispensing quality and production efficiency. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a glue bubble detection and removal device that ensures that the glue fed into the dispensing machine is free of bubbles.

[0005] The glue discharge assembly includes a three-way valve, which includes a glue inlet, a first glue outlet, and a second glue outlet. The glue inlet is connected to a second pipe connector via a connecting pipe. The first glue outlet is used to connect to a waste glue bucket, and the second glue outlet is used to connect to an external glue dispensing machine.

[0006] Furthermore, the glue detection box includes a base with a light source facing the visual detection component, and also includes an upper light-transmitting glass and a lower light-transmitting glass.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] like Figures 1 to 4 As shown in the figure, an embodiment of this application discloses a glue bubble detection and discharge device, including a detection platform 1, on which a glue detection box 2 for glue to flow is provided. A first pipe connector 3 and a second pipe connector 4 are respectively provided at both ends of the glue detection box. The first pipe connector 3 is used to connect to an external glue feeding device. A visual detection component for detecting bubbles in the glue is provided above the glue detection box 2. A discharge component is provided on one side of the detection platform 1.

[0020] The glue discharge assembly includes a three-way valve 5, which includes a glue inlet 6, a first glue outlet 7, and a second glue outlet 8. The glue inlet 6 is connected to a second pipe connector 4 via a connecting pipe. The first glue outlet 7 is used to connect to a waste glue bucket, and the second glue outlet 8 is used to connect to an external glue dispensing machine.

[0021] It should be explained that a control module is also included, which is used to connect to the vision inspection component and the three-way valve 5, and to control whether the first dispensing port 7 or the second dispensing port 8 opens based on the detection result of the vision inspection component.

[0022] In specific operation, when the external glue feeding device delivers glue to the glue detection box 2 through the first pipe joint 3, the glue will flow through the glue detection box 2. At this time, the vision detection component set above the glue detection box 2 starts to work to detect whether there are air bubbles in the glue in the glue detection box 2.

[0023] If air bubbles are detected in the adhesive, the control module sends a control signal to the adhesive discharge assembly. Upon receiving the signal, the three-way valve 5 in the adhesive discharge assembly changes the position of its internal valve core, connecting the inlet 6 to the first outlet 7 and disconnecting it from the second outlet 8. In this way, the adhesive containing air bubbles flows into the inlet 6 through the connecting pipe and is discharged into the waste adhesive bin through the first outlet 7, thus preventing the adhesive containing air bubbles from entering the external dispensing machine.

[0024] If no air bubbles are detected in the adhesive, the control module will not send a signal to change the state of the three-way valve 5, or it will send a signal to maintain the current state. At this time, the inlet 6 of the three-way valve 5 remains connected to the second outlet 8, and the air-free adhesive will be smoothly delivered to the external dispensing machine through the second outlet 8 for subsequent dispensing operations.

[0025] This structure, through the integration of a dedicated glue detection box 2 and a vision inspection component, can automatically and accurately detect the presence of air bubbles in the glue. This avoids the inefficiency and issues of missed or false detections associated with manual visual inspection, effectively ensuring that the glue fed into the dispensing machine is bubble-free, thereby improving dispensing quality and production efficiency. Simultaneously, the three-way valve 5 in the glue discharge component allows for the flexible discharge of glue containing air bubbles into a waste glue bin, while delivering bubble-free glue to an external dispensing machine, further ensuring the stability and reliability of the dispensing process.

[0026] In this embodiment, the glue detection box 2 includes a base 21, on which a light source 22 facing the visual detection component is provided, and also includes an upper light-transmitting glass 23 and a lower light-transmitting glass 24. A channel for glue to flow through is provided between the upper light-transmitting glass 23 and the lower light-transmitting glass 24. The upper light-transmitting glass 23 has a first opening 25 at both ends that communicates with the channel, and the first openings 25 at both ends are respectively connected to a first pipe connector 3 and a second pipe connector 4.

[0027] During the actual inspection, the adhesive flows through a channel formed between the upper and lower transparent glass 24. A stable light source 22 emits light that penetrates the adhesive and reaches the vision inspection component. The inspection camera 95 in the vision inspection component captures and analyzes the light penetrating the adhesive. Because air bubbles in the adhesive create different optical properties than the surrounding adhesive, the inspection camera 95 can accurately identify the presence of air bubbles based on changes in light. Once an air bubble is detected, the inspection camera 95 transmits a signal to the control module.

[0028] In this embodiment, an upper fixed shell 26 and a lower fixed shell 27 are also included. The bottom of the lower fixed shell 27 is provided with a first through hole that matches the size of the light source 22. When the upper fixed shell 26 and the lower fixed shell 27 are fastened together, the upper light-transmitting glass 23 and the lower light-transmitting glass 24 are confined within the upper fixed shell 26 and the lower fixed shell 27. The upper shell, the lower shell, and the base 21 are fixedly connected by bolts. The first pipe connector 3 and the second pipe connector 4 are respectively installed at both ends of the upper shell. The two ends of the upper shell are respectively provided with second through ports. The first pipe connector 3 and the second pipe connector 4 communicate with the channel through the first through port 25 and the second through port. The upper shell is provided with a second through hole that matches the size of the light source 22.

[0029] Specifically, the upper fixing shell 26 and the lower fixing shell 27 in the above structure enable stable clamping and positioning of the upper transparent glass 23 and the lower transparent glass 24. This design greatly improves the stability and reliability of the inspection, reduces inspection errors caused by glass movement or light interference, and also serves to press the upper transparent glass 23 and the lower transparent glass 24 together, preventing adhesive from flowing out from the gaps between the upper transparent glass 23 and the lower transparent glass 24.

[0030] In this embodiment, the second through hole has a concave hole structure 28.

[0031] Specifically, the second through hole adopts a concave hole structure 28 design. This structure can ensure the accuracy of the field of view of the inspection camera 95 during inspection, enabling the inspection camera 95 to more accurately capture the changes in light after penetrating the glue, and avoid interference with the inspection results due to light reflection or refraction at the edge of the through hole.

[0032] In this embodiment, the visual inspection component includes a fixed base 91 and a fixed rod 92 mounted on the fixed base 91. A clamping block 93 is sleeved on the fixed rod 92 and the clamping block 93 is fixed to the fixed rod 92 by bolts. It also includes an L-shaped mounting block 94, which includes a horizontal plate and a vertical plate. The horizontal plate is detachably connected to the clamping block 93, and an inspection camera 95 is mounted on the vertical plate.

[0033] The horizontal plate is provided with a waist-shaped groove 96, and the clamping block 93 is provided with a mounting hole that mates with the waist-shaped groove 96.

[0034] Specifically, when it is necessary to adjust the height of the inspection camera 95, the bolts at the clamping block 93 can be loosened, the position of the clamping block 93 can be adjusted, and then the bolts at the clamping block 93 can be tightened. When it is necessary to adjust the horizontal position of the inspection camera 95, the bolts at the connection between the horizontal plate and the clamping block 93 can be loosened, and the L-shaped mounting block 94 can be moved horizontally to a suitable position by using the cooperation of the waist-shaped groove 96 and the mounting hole. Then the bolts at that position can be tightened, thereby realizing the flexible adjustment of the horizontal position of the inspection camera 95.

[0035] The aforementioned adjustment methods enable the visual inspection component to better adapt to glue inspection scenarios with different specifications and inspection requirements, further enhancing the practicality and flexibility of the device.

[0036] In this embodiment, a light shield 10 is provided on the detection platform 1, and the glue detection box 2 and the visual detection component are located inside the light shield 10.

[0037] Specifically, the light shield 10 effectively blocks external light from interfering with the inspection process. During the inspection, changes in external light may affect the accuracy of light capture by the inspection camera 95 in the visual inspection component. The light shield 10 isolates the glue inspection box 2 and the visual inspection component from external light, creating a relatively stable and independent light environment for the inspection process, thereby greatly improving the accuracy and reliability of the inspection.

[0038] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
