[0033] One embodiment of this utility model proposes an automatic dispensing device based on CIPG process, referring to... Figure 1 , Figure 2 ,include:

[0034] Control cabinet 1;

[0035] The three-axis module includes an X-axis linear drive mechanism 21, a Y-axis linear drive mechanism 22 and a Z-axis linear drive mechanism 23. The Y-axis linear drive mechanism 22 is slidably connected to the X-axis linear drive mechanism 21 along the x-direction, and the Z-axis linear drive mechanism 23 is slidably connected to the Y-axis linear drive mechanism 22 along the y-direction.

[0036] Cleaning mechanism 3, which is used to clean the adhesive coating area of ​​the workpiece;

[0037] The glue application mechanism 4 is used to apply glue to the glue application area of ​​the workpiece;

[0038] The inspection mechanism includes a first inspection mechanism 61 for inspecting the dimensions of the glued area on the workpiece, a second inspection mechanism 62 for measuring the height between the workpiece and the glued mechanism 4, and a third inspection mechanism 63 for inspecting the glued strip after it has been applied.

[0039] Support plate 5 is mounted on the Z-axis linear drive mechanism 23. The cleaning mechanism 3, the glue application mechanism 4 and the detection mechanism are all mounted on the support plate 5.

[0040] This embodiment improves the structure of existing automatic dispensing devices by adding a cleaning mechanism 3, a first detection mechanism 61, and a second detection mechanism 62. The cleaning mechanism 3 cleans the workpiece area to be glued before dispensing, removing impurities and improving dispensing quality. The first detection mechanism 61 accurately measures the position and size of the area to be glued before dispensing, ensuring the accuracy of the dispensing path and reducing defective products due to dimensional deviations. The second detection mechanism 62 monitors and adjusts the height between the dispensing mechanism 4 and the workpiece in real time during the dispensing process, avoiding uneven glue thickness caused by uneven workpiece or slight displacement of the dispensing mechanism 4.

[0041] CIPG (Compound Injection Gasket) is a method that involves dispensing or injecting liquid adhesive at predetermined locations, followed by curing to form a robust and durable seal or gasket. In this embodiment, combining CIPG with an automated dispensing device allows for more precise dispensing, reduces the possibility of adhesive flow or spread, and ensures product quality and consistency.

[0042] Specifically, the three-axis module includes an X-axis linear drive mechanism 21, a Y-axis linear drive mechanism 22, and a Z-axis linear drive mechanism 23. Two sets of Y-axis linear drive mechanisms 22 are located on either side of the X-axis linear drive mechanism 21. The X-axis linear drive mechanism 21 is mounted on the two sets of Y-axis linear drive mechanisms 22, allowing it to move along the Y-axis. The Z-axis linear drive mechanism 23 is slidably connected to the Y-axis linear drive mechanism 22 along the Y-axis. A support plate 5 is slidably mounted on the Z-axis linear drive mechanism 23. A cleaning mechanism 3, a gluing mechanism 4, and a detection mechanism are mounted on the support plate 5. Therefore, the support plate 5 can move axially in the X, Y, and Z directions. Furthermore, the mechanisms mounted on the support plate 5 can also perform precise spatial movements in multiple positions, greatly improving the efficiency and accuracy of the automated production line.

[0043] In this embodiment, the X-axis linear drive mechanism 21, the Y-axis linear drive mechanism 22, and the Z-axis linear drive mechanism 23 adopt motor lead screw drive modules commonly used in the prior art.

[0044] When the device starts working, the first detection mechanism 61 is activated to accurately measure the position and size of the area to be coated. The cleaning mechanism 3 cleans the area to be coated according to the coating path obtained by the first detection mechanism 61. After cleaning, the coating mechanism 4 applies adhesive to the area to be coated according to the preset coating path. The second detection mechanism 62 monitors the relative height change between the coating mechanism 4 and the coating position in real time. During the coating process, the coating mechanism 4 automatically adjusts parameters such as coating path, speed and pressure according to the measurement results of the first detection mechanism 61 and the real-time monitoring information of the second detection mechanism 62. After the coating is completed, the third detection mechanism 63 is activated to perform quality inspection on the coated workpiece.

[0045] Furthermore, the cleaning mechanism 3 includes a plasma direct spray gun. In this embodiment, referring to... Figure 3 The plasma direct spray gun is fixedly mounted on the support plate 5 via a spray gun mounting plate 621. The plasma direct spray gun is also connected to an external bellows, the other end of which is connected to external equipment such as a plasma generator and a gas source, forming a complete cleaning system. When the plasma direct spray gun receives a start signal, it receives plasma and high-energy gas from the plasma generator through the bellows. These gases are accelerated inside the spray gun and converted into a high-speed plasma jet, which is directly sprayed onto the surface of the workpiece to be cleaned. The plasma jet has the characteristics of high temperature, high speed, and high energy, and can quickly decompose and remove oil, dust, and other impurities from the workpiece surface without damaging it. The plasma direct spray gun is an existing device that uses plasma technology commonly used in existing technologies. This technology ionizes gas into plasma through a specific device and utilizes the active components of the plasma to clean the workpiece surface.

[0046] Furthermore, referring to Figure 4 The first detection mechanism 61 includes a camera mounting bracket 611, a camera 612, a light source mounting bracket 613, and a light source 614. The camera 612 is fixedly mounted on the support plate 5 via the camera mounting bracket 611, and the light source 614 is fixedly mounted on the support plate 5 via the light source mounting bracket 613 and is located below the camera 612.

[0047] In this embodiment, when camera 612 receives a start signal, the three-axis module moves camera 612 to directly above the adhesive application area, enabling camera 612 to capture an image of the adhesive application area. The captured image data is then transmitted to the image processing system to accurately measure the dimensional parameters of the adhesive application area, namely, the width and shape of the area to be adhesiveed. This allows the adhesive application mechanism 4 to apply adhesive to the workpiece based on the image data fed back by the first detection mechanism 61, thereby reducing the generation of defective products. In this embodiment, light source 614 is used to illuminate the area to be measured, making the image of the area clearer and thus improving the accuracy of the shooting results.

[0048] Furthermore, the camera mounting bracket 611 is provided with first oblong holes 615 distributed along the Z-axis direction. The camera mounting bracket 611 is provided with fixing bolts, which pass through the first oblong holes 615 to fix the camera mounting bracket 611 and the support plate 5. In this embodiment, the camera mounting bracket 611 is provided with first oblong holes 615 distributed along the height direction. The camera mounting bracket 611 is provided with fixing bolts, which can pass through the first oblong holes 615 and slide up and down, thereby adjusting the height of the camera 612 and thus adjusting the distance between the camera 612 and the light source 614. By adjusting the height of the camera 612, it can adapt to the height requirements of different workpieces, improving the flexibility of the equipment.

[0049] Furthermore, the light source mounting bracket 613 is provided with second oblong holes 616 distributed along the Y-axis direction. The light source mounting bracket 613 is provided with fixing bolts, which pass through the second oblong holes 616 to fix the light source mounting bracket 613 and the support plate 5. In this embodiment, the light source mounting bracket 613 is provided with second oblong holes 616 distributed along its length direction. The light source mounting bracket 613 is provided with fixing bolts, which can pass through the second oblong holes 616 and slide left and right, thereby adjusting the angle of the light source 614. By adjusting the angle of the light source 614, the lighting effect can be optimized, reducing the impact of shadows and reflections on image capture, which is beneficial for the camera 612 to capture clearer images, thereby improving the accuracy of subsequent image processing and measurement.

[0050] Furthermore, referring to Figure 3 and Figure 5The second detection mechanism 62 is installed on the first detection mechanism 61. The second detection mechanism 62 includes a mounting plate 621 and a laser height measurement module 622. The laser height measurement module 622 is fixedly installed on the light source mounting bracket 613 via the mounting plate 621. In this embodiment, the mounting plate 621 is fixedly installed on the light source mounting bracket 613. This installation structure saves equipment space, making the entire device more compact and reducing the equipment footprint. By integrating the first detection mechanism 61 and the second detection mechanism 62 together, multiple detection functions can be realized simultaneously, i.e., height measurement can be performed while capturing images, thereby optimizing the workflow and improving detection efficiency. The mounting plate 621 has several through holes, including a second mounting hole for fixing the mounting plate 621 to the light source mounting bracket 613 and a third mounting hole for fixing the laser height measurement module 622 on the mounting plate 621. By providing several through holes on the mounting plate 621, the position and angle of the laser height measurement module 622 can be flexibly adjusted to adapt to different measurements. Requirements: The laser height measurement module 622 is fixedly installed on the light source mounting bracket 613 via the mounting plate 621. It is used to measure the height between the glue application mechanism 4 and the workpiece during the glue application process. The laser height measurement module 622 utilizes the discreteness and directionality of laser light to determine the height between the glue application mechanism 4 and the workpiece through light reflection and refraction, and feeds the measurement results back to the control panel of the control cabinet to control the height distance between the glue application mechanism 4 and the workpiece. This avoids uneven glue strip thickness at the glue application point due to changes in the height between the glue application mechanism 4 and the workpiece during the glue application process, which helps to reduce the generation of defective products and improve the glue application quality.

[0051] Furthermore, referring to Figure 6 The third detection mechanism 63 includes a rotary motor 631 and a 3D camera 632. The rotary motor 631 is fixedly mounted on the support plate 5. The driving end of the rotary motor 631 is fixedly connected to the 3D camera 632 and drives the 3D camera 632 to rotate.

[0052] Specifically, the rotary motor 631 is fixedly mounted on the support plate 5 via the motor mounting plate 621. The drive end of the rotary motor 631 is fixedly connected to the 3D camera 632 and drives the 3D camera 632 to rotate, which can meet the shape and inspection requirements of different workpieces. The scanning range of the 3D camera 632 can be flexibly controlled by the rotation angle of the rotary motor 631, thereby realizing the scanning and inspection of the workpiece from all directions.

[0053] Furthermore, referring to Figure 3The adhesive application mechanism 4 includes a screw valve, which is fixedly connected to the support plate 5 via a screw valve mounting bracket. In this embodiment, the screw valve can be a single-set screw valve or a double-set screw valve; the structure of the screw valve is not limited here.

[0054] Furthermore, referring to Figure 3 The support plate 5 has a plurality of first mounting holes 51 along the Z-axis direction, and both the glue application mechanism 4 and the cleaning mechanism 3 have fixing holes corresponding to the first mounting holes 51. In this embodiment, the support plate 5 has a plurality of first mounting holes 51, and the glue application mechanism 4 and the cleaning mechanism 3 can be flexibly installed on the support plate 5 according to actual needs. By adjusting the angle and position of the glue application mechanism 4 and the cleaning mechanism 3, the glue application and cleaning effects can be optimized. Furthermore, when the glue application mechanism 4 or the cleaning mechanism 3 needs to be repaired or replaced, they can be easily removed from the support plate 5 by disassembling the fixing bolts, which facilitates equipment maintenance and reduces downtime and maintenance costs.

[0055] Furthermore, referring to Figure 1 The control cabinet 1 is equipped with a warning light 11 on its top. In this embodiment, the warning light 11 is a three-color warning light 11, used to reflect the operating status and fault information of the equipment in real time. By installing the warning light 11 on the top of the control cabinet 1, the operator can easily observe the status of the warning light 11, and promptly detect and handle problems.

[0056] In this embodiment, a safety light curtain is also installed at the door of the control cabinet 1 to prevent personal injury. The safety light curtain can monitor the position of personnel or objects in the danger zone in real time. Once personnel or objects are detected entering the danger zone, the safety light curtain will quickly trigger the safety system to stop the operation of the equipment, thereby avoiding accidents and reducing downtime and production interruptions caused by safety accidents, thus improving production efficiency. The control cabinet 1 is also equipped with a control panel, and the warning light 11 and the safety light curtain are electrically connected to the control panel.
