Description

Technical Field

[0001] This invention relates to the field of visual monitoring of adhesive weight, specifically a process for monitoring adhesive weight using CCD vision. Background Technology

[0002] In the fields of industrial automation and intelligent manufacturing, adhesive dispensing is a crucial supporting link in core processes such as electronic component packaging and product structure bonding. The weight stability of adhesive dispensing directly determines the bonding strength, sealing performance, and batch consistency of the product, playing a decisive role in the quality and reliability of the end product. As downstream industries such as consumer electronics and automotive electronics continue to upgrade their requirements for product refinement and high reliability, the market has placed more stringent standards on the weight control accuracy, production efficiency, and multi-scenario adaptability of adhesive dispensing processes. Against this backdrop, it is necessary to introduce an adhesive weight monitoring process based on CCD vision inspection technology to achieve high-precision, real-time, and intelligent control of dispensing volume.

[0003] While existing visual monitoring technologies can meet the basic requirements of routine adhesive weight monitoring, in actual industrial mass production scenarios, the workpieces to be glued still require additional specialized fixtures for positioning and clamping, generally lacking integrated automatic clamping capabilities that seamlessly integrate with automated production lines. This technological limitation not only significantly increases the time spent on workpiece clamping, positioning calibration, and unloading, greatly extending the overall processing cycle of a single batch of products, but also directly disrupts the continuous flow of the dispensing operation, causing equipment idle time and production line imbalance. The combined effect of these shortcomings not only reduces the operating efficiency and output capacity of the dispensing process, but also introduces the risk of positioning deviation due to increased manual intervention, affecting the consistency of adhesive weight distribution. Ultimately, the actual performance of the entire process falls far short of the expected standards for high-precision, high-efficiency industrial production, resulting in an overall unsatisfactory process performance.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] This embodiment provides a process for monitoring the weight of adhesive using CCD vision;

[0033] Please see Figure 1 - Figure 8As shown, the device includes a frame 1, with a sliding groove 2 in the middle of the frame 1. Support columns 3 are fixed on both sides of the frame 1, and through slots 4 are formed in the middle of each support column 3. A computer 5 is mounted on one side of one of the support columns 3. A three-axis motion platform 6 is fixed to the upper end of both support columns 3. A dispensing head 7 and a monitoring camera 8 are mounted on the output end of the three-axis motion platform 6. A through hole 9 is formed at the output end of the three-axis motion platform 6, and a connecting structure is provided on the inner wall of the through hole 9. The connecting structure includes a connecting rod 10, with sliding frames 11 slidably connected to both ends of the connecting rod 10. Grooves 12 are formed on the adjacent sides of the two sliding frames 11. Fixed frames 13 are fixed to the lower ends of the two sliding frames 11, and the lower ends of the two fixed frames 13 are rotatably connected. The system includes two connecting frames 14, each with a connecting rod 15 rotatably connected to its lower end. Two sliders 16 are fixed to both ends of each connecting rod 15. Each slider 16 has a slot 17 on both sides, and a locking block 18 is installed on the inner wall of each slot 17. A limit bracket 19 is fixed to one end of every two adjacent locking blocks 18. Through the deep integration of the dispensing head 7 and the monitoring camera 8 with the database system built into the computer 5, a complete, high-precision dispensing closed-loop control system is constructed: Before the dispensing operation starts, the computer 5 first calls the corresponding product line parameters pre-stored in the database, automatically configures the initial dispensing pressure, dispensing speed, and movement trajectory of the dispensing head 7, and calibrates the shooting angle of the monitoring camera 8. The focus range and data acquisition frequency ensure that the equipment is in optimal working condition from startup. During the dispensing process, the monitoring camera 8 synchronously acquires two-dimensional images and three-dimensional data of the dispensing area in real time, and transmits the acquired real-time data stream to the computer 5 at high speed. The computer 5 calls the pre-built mathematical model of the visual characteristics of glue weight in the database, and combines it with auxiliary data such as the current glue type and ambient temperature and humidity to quickly analyze the real-time acquired visual data, accurately inverting the actual weight and distribution uniformity of the current glue dot. If the analysis result shows that there is a deviation in the glue amount, the computer 5 immediately initiates the control command: on the one hand, it feeds back a signal to the drive system of the dispensing head 7 to dynamically fine-tune the dispensing speed, dispensing pressure, or The dispensing head 7 moves along a trajectory to achieve real-time correction of the glue volume. On the other hand, it simultaneously records deviation data, adjusted parameters, and glue volume detection results into the database, forming a complete data chain from problem to control to result. Meanwhile, the database continuously accumulates dispensing data for each batch of products and periodically performs statistical mining through the data analysis module of computer 5 to optimize the adaptation accuracy of the mathematical model of glue weight visual characteristics. It can also provide data support for parameter matching for different product lines. When switching workpiece types, it is only necessary to call the historical optimal parameters of the corresponding product in the database to quickly complete equipment debugging, significantly shorten the production changeover cycle, and realize intelligent and efficient management and control of the dispensing process.

[0034] Please refer to it again. Figure 1 - Figure 8As shown, the outer surface of the connecting rod 10 is slidably connected to the inner wall of the through hole 9, and the outer surfaces of both ends of the connecting rod 10 are slidably connected to the inner walls of the two grooves 12. The two grooves 12 are opened on the near sides of the two sliding frames 11. The outer surfaces of the two sliding frames 11 are slidably connected to the inner walls of the two through slots 4. The two sliding frames 11 are arranged opposite to each other. The cross section of each sliding frame 11 is T-shaped. The lower ends of the two sliding frames 11 are fixed to the upper ends of the two fixed frames 13. The lower ends of the two fixed frames 13 are rotatably connected to the far ends of the two connecting frames 14. The near ends of the two connecting frames 14 are rotatably connected to the outer surfaces of the two connecting rods 15. The two ends of the two connecting rods 15 are fixed to the middle of the two sliders 16. The outer surfaces of the two sliders 16 are slidably connected to the inner walls of both sides of the slide groove 2. Four slots 17 are opened on both sides of the two sliders 16. The outer surfaces of the four locking blocks 18 are in contact with the inner walls of the four slots 17. The near ends of the four locking blocks 18 are fixed to the far ends of the two limiting frames 19. The outer surfaces of the four limiting frames 19 are slidably connected to the upper surfaces of both sides of the frame 1.

[0035] The specific implementation process is as follows: The three-axis motion platform 6 drives the dispensing head 7 at its end to move synchronously with the monitoring camera 8, completing the product dispensing and glue volume monitoring operations simultaneously; relying on the CCD monitoring camera 8 and 3D data, the data is transmitted to the computer 5. The computer 5 calls the pre-built mathematical model of glue weight visual characteristics in the database to quickly analyze the current glue volume accuracy; if a glue volume deviation is detected, a signal is immediately fed back to the dispensing control system, driving the dispensing head 7 to dynamically adjust parameters such as dispensing speed and dispensing pressure. At the same time, the database records the adjustment data and dispensing effect, forming a fully automated control process from acquisition to analysis, adjustment, and recording. This ensures glue volume consistency and accumulates data support for subsequent process optimization; subsequently, the automatic control system will be used to replace manual fine-tuning operations, reducing the frequency of first-piece inspections. After the basic production line completes the verification, the entire system will be replicated and promoted to other production lines and adapted and debugged for different glue path configurations;

[0036] Meanwhile, the through hole 9 opened at the drive end of the three-axis motion platform 6 can drive the connecting rod 10, which is slidably connected to its inner wall, to move synchronously. Under the limiting action of the groove 12 on the near side of the two sliding frames 11, the moving connecting rod 10 drives the two sliding frames 11 to slide along the through groove 4 opened in the middle of the support column 3. The two sliding frames 11 drive the fixed frame 13 fixed at its lower end to move synchronously. The fixed frame 13 drives the two connecting rods 15 that rotate near the two connecting frames 14 through the connecting frame 14 rotatably connected at its lower end. The two sliders 16 fixedly connected to the two connecting rods 15 slide in the opposite direction along the sliding groove 2 opened in the middle of the frame 1. The two sliders 16 that move in the opposite direction drive the two limiting frames 19 fixed near the four blocks 18 to move in the opposite direction by means of the locking groove 17 opened in its inner wall and the locking block 18, thereby realizing automatic positioning and clamping of the workpiece to be glued placed in the middle of the frame 1. For workpieces of different sizes, only the assembly position of the clamping block 18 in the clamping slot 17 needs to be adjusted to adapt to the workpiece. No additional special positioning fixture is required, which can achieve the effect of automatic positioning, effectively improve the continuity of dispensing operation, and thus optimize the overall process operation.

[0037] Example 2

[0038] During the dispensing process, the adhesive is prone to spreading due to its fluidity. If the adhesive is not semi-solidified when the parts are subsequently removed, it is very easy for it to flow off-center. Allowing it to stand naturally until it is semi-solidified is time-consuming, which seriously restricts process efficiency. Therefore, a rapid adhesive solidification step needs to be added after dispensing to promote the adhesive to reach a semi-solidified state as soon as possible to suppress flow, ensure the accuracy of the dispensing shape, and facilitate the subsequent pressing and assembly process, thereby improving the overall process efficiency.

[0039] Please see Figure 1 - Figure 8 As shown, a rapid semi-solidification function has been added based on Example 1;

[0040] Please refer to it again. Figure 1 - Figure 8As shown, a fixing block 20 is fixed to the same end of each of the two sliders 16. A rack 21 is fixed to the adjacent side of each of the two fixing blocks 20. A gear 22 is meshed between the two racks 21. A stabilizing rod 23 is fixed to the middle of the gear 22. A fan impeller 24 is fixed to the other end of the stabilizing rod 23. A support base 25 is rotatably connected to the outer surface of the middle part of the stabilizing rod 23. The two fixing blocks 20 are fixed to one end of each of the two sliders 16 at opposite ends. The two fixing blocks 20 are staggered. The adjacent side of each of the two fixing blocks 20 is fixed to the opposite side of each of the two racks 21. The adjacent side of each of the two racks 21 meshes with both sides of the gear 22. The middle part of the gear 22 is fixed to one end of the stabilizing rod 23. The other end of the stabilizing rod 23 is fixed to the middle part of the fan impeller 24. The outer surface of the middle part of the stabilizing rod 23 is rotatably connected to the inner wall of the support base 25. One end of the support base 25 is fixed to one side of the frame 1. The vertical section of the support base 25 is L-shaped, and the vertical section of the stabilizing rod 23 is cross-shaped.

[0041] The specific implementation process is as follows: Through the through hole 9 opened at the drive end of the three-axis motion platform 6, the connecting rod 10 slidably connected to its inner wall can move synchronously. The two sliding frames 11 connected to both ends of the connecting rod 10, through the transmission of the fixed frame 13, the connecting frame 14 and the connecting rod 15, drive the two sliders 16 to move in the opposite direction along the slide groove 2. The sliders 16 moving in the opposite direction drive the two sets of staggered fixed blocks 20 fixed at one end to move synchronously in the opposite direction, thereby driving the racks 21 on the adjacent side of the fixed blocks 20 to slide synchronously in the opposite direction. The racks 21 moving in the opposite direction mesh with the gears 22, driving the gears 22 to rotate; the stabilizing rod 23 fixed in the middle of the gears 22 rotates synchronously under the support and limit of the support seat 25 on the frame 1, thereby driving the fan impeller 24 at the other end of the stabilizing rod 23 to rotate at high speed;

[0042] After the dispensing operation is completed, as the two limit frames 19 separate from each other, the high-speed rotating fan impeller 24 generates directional airflow, which precisely blows the glue area on the workpiece surface, accelerating the glue to enter a semi-solid state and achieving a rapid semi-solidification effect. This effectively shortens the standing time required for the glue to semi-solidify, avoids the risk of flow deviation, ensures the smooth progress of subsequent pressing and assembly processes, and significantly improves the overall process efficiency.

[0043] Example 3

[0044] After dispensing, the product adheres tightly to the placement table, making subsequent manual or mechanical removal operations significantly inconvenient and affecting process flow efficiency. Therefore, a product lifting structure needs to be added to automatically lift the product off the placement table after dispensing and partial adhesive setting, thus optimizing the ease of removal.

[0045] Please see Figure 1 - Figure 8 As shown, a convenient retrieval function has been added based on Embodiment 1;

[0046] Please refer to it again. Figure 1 - Figure 8 As shown, each of the two sliders 16 has a drive rod 26 fixed in the middle. The outer surfaces of the two drive rods 26 are slidably connected to a drive frame 27. Guide grooves 28 are provided on both sides of the drive frame 27. A top frame 29 is fixed at the upper end of the drive frame 27. A stabilizing groove 30 is provided in the middle of the slide groove 2. The two ends of the two drive rods 26 are fixed in the middle of the two sliders 16. The outer surfaces of the two drive rods 26 are slidably connected to the inner walls of the two guide grooves 28. The two guide grooves 28 are symmetrically opened on both sides of the drive frame 27. The outer surface of the drive frame 27 is slidably connected to the inner wall of the stabilizing groove 30. The stabilizing groove 30 passes through the upper side of the frame 1. The cross-section of the stabilizing groove 30 is T-shaped. The lower end of the top frame 29 is fixed to the middle of the upper end of the drive frame 27. The outer surface of the top frame 29 is in contact with the inner wall of the stabilizing groove 30.

[0047] The specific implementation process is as follows: Through the through hole 9 at the drive end of the three-axis motion platform 6, the connecting rod 10, which is slidably connected to its inner wall, can move synchronously. The two sliding frames 11 connected to both ends of the connecting rod 10, through the transmission of the fixed frame 13, the connecting frame 14 and the connecting rod 15, drive the two sliders 16 to move in the opposite direction along the slide groove 2. The sliders 16 moving in the opposite direction drive the two driving rods 26 fixed in the middle to move synchronously. The two driving rods 26 moving in the opposite direction are adapted to and cooperate with the two inclined guide grooves 28 to form a squeezing force on the driving frame 27. The driving frame 27 slides smoothly under the limiting guidance of the stabilizing groove 30, and drives the top frame 29 fixed in the middle to move synchronously.

[0048] After the dispensing operation is completed, as the two limit frames 19 separate, the high-speed rotating fan impeller 24 generates a directional airflow that precisely blows the adhesive area on the workpiece surface, causing the adhesive to quickly enter a semi-solid state. As the two sliders 16 continue to move away from each other in opposite directions, the drive rod 26, through the oblique transmission action of the guide groove 28, pushes the drive frame 27 upward, which in turn drives the top frame 29 to lift the workpiece off the placement table surface, forming a safe retrieval gap and achieving the effect of convenient retrieval. This avoids the risk of adhesion and scratches during retrieval and greatly improves the convenience of retrieval operations.
