Description

Technical Field

[0001] The invention relates to the technical field of glue dispensing machines, and in particular to an online glue dispensing visual recognition device. Background Art

[0002] Glue dispensing machine, also known as glue coating machine, glue dripping machine, glue spraying machine, glue filling machine, etc., is an automated machine that specializes in controlling fluids and dripping and applying fluids to the surface or inside of products. It can achieve three-dimensional and four-dimensional path dispensing, precise positioning, precise glue control, no drawing, no glue leakage, and no glue dripping. Glue dispensing machine is mainly used for glue, paint and other liquids in product processes to accurately point, inject, apply and drip to the precise position of each product, and can be used to achieve dotting, drawing lines, circles or arcs.

[0003] After searching, the patent with the patent announcement number CN207473189U discloses a two-way visual recognition device for a dispensing machine based on visual positioning technology. Although the light emitted by the light source reaches the prism through the light guide cavity when the device is in use, it is refracted to the reflector through the triangular prism, and then reflected to the lens through the reflector and the light guide hole. The light emitted by the lower light source reaches the prism through the light guide cavity, and is refracted to the lens through the triangular prism and the light guide hole, so as to measure the coaxial objects in two opposite directions. However, when dealing with the recognition task after the transparent glue is applied, since the glue is usually transparent or translucent after application, it is difficult to immediately and accurately judge the quality of the glue application, such as the amount of application, uniformity, whether there is leakage or over-application, etc., when only relying on the visual lens for recognition. This transparency reduces the contrast between the glue and the background (such as the substrate), thereby increasing the difficulty of recognition. Although the device realizes two-way visual recognition, when dealing with transparent glue, a more complex image processing algorithm is required to improve the recognition accuracy, which will increase the amount of calculation and affect the real-time performance of recognition. Since the recognition process is highly dependent on the performance of the visual lens and the accuracy of the image processing algorithm, any lens contamination, wear or algorithm defects may lead to recognition failure or increased errors. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an online dispensing visual recognition device, which solves the problems raised in the background technology.

[0005] The solution of the present invention to solve the above technical problems is as follows:

[0006] An online dispensing visual recognition device comprises a body, a storage cabinet is installed on the body, a conveyor belt is installed on the body, a base is installed on one side of the body, a mechanical arm is installed on the base, and a machine head is installed on the mechanical arm.

[0007] The mechanical arm is provided with a connecting seat, a dividing plate is provided at the bottom end of the connecting seat, the connecting seat is rotatably mounted on the base through the dividing plate, a first connecting arm is rotatably mounted on the connecting seat, a second connecting arm is rotatably mounted on the first connecting arm, and a machine head is rotatably mounted on one end of the second connecting arm away from the first connecting arm;

[0008] The machine head is provided with a substrate, a fluorescent sensor is installed on one surface of the substrate, an industrial camera is installed on the side surface of the substrate facing away from the fluorescent sensor, a protective cover is installed on the substrate outside the industrial camera, a laser ranging sensor is installed on one end surface of the substrate, a glue dispensing head is installed on the side end surface of the substrate facing away from the laser ranging sensor, the glue dispensing head is provided with two feeding interfaces, and the two feeding interfaces are respectively connected to glue and fluorescent agent through conduits.

[0009] Based on the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the cross section of the substrate is trapezoidal, and the laser distance measuring sensor and the dispensing head are respectively mounted on both side end surfaces of the substrate through a first mounting seat and a second mounting seat.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] The trapezoidal cross-section design enhances the overall strength and rigidity of the baseplate, making it more stable when bearing the weight of the dispensing head and laser distance sensor, as well as the vibration and shock generated during operation. This stability is essential to ensure the accuracy of dispensing and laser distance measurement. The trapezoidal design allows for more efficient use of space, especially in compact automated production environments. By mounting the laser distance sensor and dispensing head on both sides of the baseplate, mutual interference between them can be reduced while ensuring that they each have sufficient operating space. This layout also helps to reduce the overall size of the entire device and improve the integration of the equipment.

[0013] Furthermore, the conveyor belt is provided with a rotating shaft, which is rotatably mounted on the machine body through a bearing seat, a toothed disc is mounted on the rotating shaft, a second chain is transmission-mounted on the toothed disc, and a first chain plate and a second chain plate are mounted on the second chain.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] The shaft is mounted on the machine body through the bearing seat, ensuring the stable rotation of the shaft. The bearing seat is not only easy to install, but also can extend the service life of the shaft and reduce the failure rate of the machine. The transmission design of the toothed disc and the second chain improves the transmission efficiency, because the chain transmission has the characteristics of high transmission efficiency and can withstand large torque. This design enables the power to be efficiently transmitted from the motor to the conveyor belt, thereby driving the movement of the conveyor belt. This design makes the entire transmission system compact and occupies little space, which is easy to integrate in the limited equipment space. At the same time, it also improves the overall aesthetics of the equipment.

[0016] Furthermore, the second chain is composed of inner links and outer links, and a fixing plate is provided on the outer links, and a fixing plate is provided on one side of the outer links.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] This chain design enhances the stability of the overall structure. The combination of inner and outer links makes the chain more stable during transmission, reducing transmission errors caused by loose or deformed chains. The design of the fixed plate further strengthens the outer link, enabling it to withstand greater tension and torque, thereby improving the stability and reliability of the entire transmission system. The precise matching of the inner and outer links ensures the accuracy of the transmission. Through the transmission connection between the toothed disc and the second chain, precise speed and position control can be achieved, which is essential for dispensing operations that require high-precision positioning.

[0019] Furthermore, identification plates are provided on both sides of the second chain plate, and a connecting block is provided at the bottom end of the second chain plate, baffles are provided at both ends of the first chain plate, and a connecting block is also provided at the bottom end of the baffle, and the first chain plate and the second chain plate are connected and fixed to the second chain through the connecting blocks.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] The first chain plate, the second chain plate and the second chain are firmly connected by the connecting block to form a stable transmission structure. This connection method reduces the vibration and noise caused by the relative movement between the chain and the chain plate, and improves the stability and reliability of the overall structure. The identification plate is used in conjunction with detection elements such as photoelectric sensors to monitor the movement state of the conveyor belt or perform position identification. By fixing the identification plate on the second chain plate, its stability and accuracy during the transmission process can be ensured, thereby improving the accuracy and reliability of the transmission. At the same time, the precise design and processing of the connecting block ensures a good fit between the chain plate and the chain, reducing the transmission error caused by improper fit.

[0022] Furthermore, support plates are installed at both ends of the body through reinforcement plates, and baffles are installed on the support plates to block materials on the conveyor belt. A motor is installed inside the body, and the motor is connected to the rotating shaft at one end of the conveyor belt through a first chain.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] By installing reinforcement plates at both ends of the machine body and supporting plates on this basis, the structural stability of the entire conveying system is significantly enhanced. This design can withstand the weight of the conveyor belt and the materials on it, reducing deformation or damage caused by long-term operation or carrying heavy objects. The motor is connected to the rotating shaft at one end of the conveyor belt through the first chain. This chain drive method has the advantages of large force transmission, accurate transmission ratio, and compact structure, which can ensure the smooth and reliable operation of the conveyor belt. The baffle installed on the support plate is used to block the materials on the conveyor belt to ensure that the materials maintain a stable position during the transmission process to prevent them from shifting or sliding. This is especially important for materials that require precise dispensing, because any slight position deviation may lead to inaccurate dispensing. The precise control of the motor combined with the chain drive can achieve precise adjustment of the conveyor belt speed to meet the needs of different materials and dispensing processes.

[0025] Furthermore, a photoelectric sensor is installed on one side of the machine body, and the rotation speed of the conveyor belt is determined by detecting the time interval each time the identification plate is identified by the photoelectric sensor.

[0026] The beneficial effects of adopting the above further scheme are:

[0027] Photoelectric sensors work by emitting light signals and receiving their reflected or blocked signals, without direct contact with the conveyor belt or identification plate. This non-contact measurement method avoids the wear and error that may be caused by long-term friction in traditional mechanical contact sensors, thereby extending the service life of the equipment. Photoelectric sensors can accurately detect the time intervals between each passage of the identification plate, and the precise speed of the conveyor belt can be obtained by calculating these time intervals. Since photoelectric sensors have the characteristics of fast response speed and high measurement accuracy, they can provide accurate and reliable speed data. Photoelectric sensors can monitor the speed changes of the conveyor belt in real time and provide real-time feedback signals to the control system. This enables the control system to adjust the dispensing speed, position and other parameters in time according to the changes in speed to ensure the accuracy and consistency of dispensing.

[0028] Furthermore, a positioning groove is provided on the substrate, a sliding groove is provided on the positioning groove, the industrial camera is installed in the positioning groove, and a fixing bolt is installed on the industrial camera, and the fixing bolt and the sliding groove cooperate with each other to lock and fix the industrial camera.

[0029] The beneficial effects of adopting the above further scheme are:

[0030] The positioning groove on the base plate provides an accurate installation position for the industrial camera, ensuring the position accuracy of the camera during installation. This design avoids shooting errors caused by position offset during installation. By directly installing the industrial camera in the positioning groove, the installation process is simplified and the installation difficulty is reduced. At the same time, the design of the positioning groove also makes the camera more stable during installation and less prone to shaking. The slide groove on the positioning groove provides convenience for adjusting the position of the industrial camera. After sliding the camera and adjusting it to the appropriate position, the fixing bolt and the slide groove are used to lock and fix it, so as to achieve flexible adjustment and precise fixation of the camera position. The fixing bolt and the slide groove can ensure the stability of the industrial camera after installation. This design avoids the loosening or falling of the camera due to vibration or external force during use, and ensures the stability and reliability of shooting.

[0031] Furthermore, a connector is installed on the top of the base plate, and the base plate is rotatably connected to the second connecting arm via the connector.

[0032] The beneficial effects of adopting the above further scheme are:

[0033] The design of the connector enables a flexible rotational connection between the substrate and the second connecting arm. This design allows the substrate to rotate or tilt freely within a certain range, thereby meeting the needs of different application scenarios. By adjusting the angle and position between the substrate and the second connecting arm, the working posture of the entire device can be easily adjusted to adapt to different working environments or task requirements. In application scenarios that require precise control of position or angle, such as automated production lines, precision instruments, etc., by adjusting the connection angle between the substrate and the second connecting arm, the layout and workflow of the entire device can be optimized to improve work efficiency. The flexible rotational connection reduces the installation error and cumulative error caused by the fixed connection, and improves the accuracy and reliability of the entire device.

[0034] Furthermore, the fluorescence sensor is mounted on a surface of the substrate on a side away from the industrial camera through a third mounting seat, and the fluorescence sensor is located below the slide slot.

[0035] The beneficial effects of adopting the above further scheme are:

[0036] The fluorescent sensor is installed on the side of the substrate away from the industrial camera and below the chute. This layout effectively utilizes the space of the substrate and avoids spatial conflicts and interference between different components. The compact layout makes the entire device more compact, which is conducive to installation and use in a limited space, especially in automated production lines or inspection equipment with limited space. The fluorescent sensor and the industrial camera are installed on different sides of the substrate, reducing the light interference between the two. This helps to ensure that the images captured by the industrial camera are clear and accurate, while ensuring that the fluorescent sensor can work stably and reliably. The location of the fluorescent sensor below the chute may mean that its measurement area is relatively independent of the shooting area of ​​the industrial camera, which helps to reduce errors caused by overlapping or crossing measurement areas and improve overall measurement accuracy.

[0037] The present invention provides an online dispensing visual recognition device, which has the following beneficial effects:

[0038] The device integrates a high-precision robotic arm and head, and with industrial cameras and laser ranging sensors, it can achieve precise control and detection of the dispensing position. Automated operation not only improves production efficiency, but also reduces human errors.

[0039] The speed of the conveyor belt is determined by the time interval of the photoelectric sensor detecting the identification plate, thereby achieving real-time monitoring and precise control of the conveyor belt speed. This helps to ensure the stability and consistency of the dispensing operation.

[0040] The dispensing head can receive glue and fluorescent agent at the same time and mix them before dispensing. This allows the glue to be directly fluorescently marked without adding additional processes, facilitating subsequent detection.

[0041] Industrial cameras are used to directly observe the dispensing position, and fluorescent sensors are used to detect fluorescent agents in the glue. The combination of the two can further confirm the location, coverage, and uniformity of the glue. This multiple detection mechanism improves the reliability of dispensing quality.

DETAILED DESCRIPTION

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] See also Figures 1 to 11 As shown, the embodiments provided by the present invention are:

[0059] Embodiment 1

[0060] An online dispensing visual recognition device includes a machine body 1, a storage cabinet 102 is installed on the machine body 1, a conveyor belt 5 is installed on the machine body 1, a rotating shaft 506 is provided on the conveyor belt 5, support plates 106 are installed at both ends of the machine body 1 through reinforcing plates 105, and baffles 107 are installed on the support plates 106, and the materials on the conveyor belt 5 are blocked by the baffles 107, and a motor 103 is installed inside the machine body 1, and the motor 103 is connected to the rotating shaft 506 at one end of the conveyor belt 5 through a first chain 104. By installing reinforcing plates 105 at both ends of the machine body 1 and installing support plates 106 thereon, the structural stability of the entire conveying system is significantly improved. This design can bear the weight of the conveyor belt 5 and the materials thereon, and reduce deformation or damage caused by long-term operation or carrying heavy objects. The motor 103 is connected to the rotating shaft 506 at one end of the conveyor belt 5 through the first chain 104. The chain transmission method has the advantages of large transmission force, accurate transmission ratio and compact structure, ensuring that the conveyor belt 5 runs smoothly and reliably. The stopper 107 on the support plate 106 is used to position the material to ensure that it does not deviate or slip during the transmission process. This is especially important for materials that require high-precision dispensing, because any slight deviation may lead to inaccurate dispensing. The precise control of the motor 103 combined with the chain drive can achieve precise adjustment of the speed of the conveyor belt 5 to meet the needs of different materials and dispensing processes. The rotating shaft 506 is rotatably installed on the body 1 through the bearing seat 505, and a toothed disc 504 is installed on the rotating shaft 506. The second chain 503 is transmission-installed on the toothed disc 504. The second chain 503 consists of an inner link 5032 and an outer link 5033, and a fixing plate 5031 is provided on the outer link 5033, and a fixing plate 5031 is provided on one side of the outer link 5033. The chain design further enhances the stability of the system.

[0061] On the other hand, the precise matching of the inner and outer chain links 5033 ensures the stability of the transmission process and reduces the transmission error caused by loose or deformed chains. The design of the fixed plate 5031 strengthens the outer chain link 5033, enabling it to withstand greater tension and torque, thereby improving the stability and reliability of the transmission system. Through the transmission connection between the toothed disc 504 and the second chain 503, the speed and position control are accurately realized, which is crucial for high-precision dispensing operations. The second chain 503 is equipped with a first chain plate 501 and a second chain plate 502. The toothed disc 504 is driven by the motor 103 to drive the second chain 503, and then the toothed disc 504 drives the first chain plate 501 and the second chain plate 502. The rotating shaft 506 is installed on the machine body 1 through the bearing seat 505 to ensure its stable rotation. The bearing seat 505 is not only easy to install, but also can extend the service life of the rotating shaft 506 and reduce the failure rate of the machine. The transmission design of the toothed disc 504 and the second chain 503 improves the transmission efficiency, thanks to the high efficiency of the chain transmission and its ability to withstand large torque. This design can efficiently transfer power from the motor 103 to the conveyor belt 5 to drive its movement. The overall transmission system has a compact structure and occupies a small space, which is convenient for integration in a limited equipment space, while improving the aesthetics of the equipment. Identification plates 5022 are provided on both sides of the second chain plate 502, and a photoelectric sensor 101 is installed on one side of the body 1. The photoelectric sensor 101 detects the time interval each time the identification plate 5022 identifies to determine the rotation speed of the conveyor belt 5, so as to facilitate the subsequent control of the speed of the conveyor belt 5. The photoelectric sensor 101 works by emitting and receiving reflected or blocked signals, without direct contact with the conveyor belt 5 or the identification plate 5022. This non-contact measurement method avoids the wear and error caused by long-term friction of traditional mechanical contact sensors, and extends the service life of the equipment.

[0062] The photoelectric sensor 101 can accurately detect the time interval of the identification plate 5022 passing through, and calculate the rotation speed of the conveyor belt 5 through these data. Since the photoelectric sensor 101 has the characteristics of fast response speed and high measurement accuracy, it can provide accurate rotation speed data, monitor the speed change of the conveyor belt 5 in real time, and provide real-time feedback for the control system. This enables the control system to adjust the dispensing speed and position in time according to the speed change, ensuring the accuracy and consistency of the dispensing operation, and the bottom end of the second chain plate 502 is provided with a connecting block 5021, the two ends of the first chain plate 501 are provided with baffles 5011, and the bottom end of the baffle 5011 is also provided with a connecting block 5021, the first chain plate 501 and the second chain plate 502 are connected and fixed to the second chain 503 through the connecting block 5021, and the first chain plate 501, the second chain plate 502 and the second chain 503 are firmly connected through the connecting block 5021, forming a stable transmission structure. This connection method reduces the relative movement between the chain and the chain plate, reduces vibration and noise, and enhances the stability and reliability of the structure. The identification plate 5022 works in conjunction with detection elements such as the photoelectric sensor 101 to monitor the motion state of the conveyor belt 5 or perform position recognition. The identification plate 5022 is fixed to the second chain plate 502 to ensure its stability and accuracy during the transmission process, thereby improving the accuracy and reliability of the transmission. The precise design and processing of the connecting block 5021 ensures a good fit between the chain plate and the chain, reducing errors caused by improper fit.

[0063] Embodiment 2

[0064] In order to facilitate moving the head to the desired position for dispensing, for example, Figure 2 As shown, the present invention also includes: the robot arm 3 is provided with a connecting seat 302, the bottom end of the connecting seat 302 is provided with a dividing plate 301, the connecting seat 302 is rotatably mounted on the base 2 through the dividing plate 301, a first connecting arm 303 is rotatably mounted on the connecting seat 302, a second connecting arm 304 is rotatably mounted on the first connecting arm 303, and a machine head 4 is rotatably mounted on the end of the second connecting arm 304 away from the first connecting arm 303.

[0065] Embodiment 3

[0066] In order to accurately detect the coating effect of the glue, for example, Figures 8 to 11As shown, the present invention also includes: the head 4 is provided with a base plate 405, the top of the base plate 405 is installed with a connector 402, the base plate 405 is rotatably connected to the second connecting arm 304 through the connector 402, so that the second connecting arm 304 drives the connector 402 to move the head 4 to a desired angle, and the base plate 405 and the second connecting arm 304 are flexibly rotatably connected through the connector 402, allowing the base plate 405 to freely rotate or tilt within a certain range to meet the needs of different application scenarios. By adjusting the angle and position of the base plate 405 and the second connecting arm 304, the device can adapt to different working environments or task requirements.

[0067] In scenes where precise position control is required, such as automated production lines and precision instruments, adjusting the connection angle can optimize the device layout and workflow, and improve work efficiency. The flexible rotation connection reduces the installation error caused by the fixed connection, and improves the overall accuracy and reliability. A fluorescent sensor 404 is installed on one side of the substrate 405. The fluorescent sensor 404 is installed on the side of the substrate 405 away from the industrial camera 406 through the third mounting seat 4041, and the fluorescent sensor 404 is located below the slide 4051. The fluorescent agent mixed in the glue is detected by the fluorescent sensor 404 to further detect and determine the position and coverage of the glue. The fluorescent sensor 404 is installed on the side of the substrate 405 away from the industrial camera 406 and is located below the slide 4051. This layout makes full use of the space of the substrate 405 and avoids spatial conflicts and interference between components. The compact layout makes the device more suitable for automated production lines or testing equipment with limited space.

[0068] The fluorescence sensor 404 and the industrial camera 406 are separately installed on different sides of the substrate 405, which reduces light interference, ensures that the image captured by the industrial camera 406 is clear and accurate, and the fluorescence sensor 404 can work stably. The fluorescence sensor 404 is located below the slide groove 4051, and its measurement area is independent of the shooting area of ​​the industrial camera 406, which reduces the overlap error, thereby improving the overall measurement accuracy. The industrial camera 406 is installed on the surface of the substrate 405 on the side away from the fluorescence sensor 404, and a protective cover 407 is installed on the substrate 405 on the outside of the industrial camera 406. A positioning groove 4052 is provided on the substrate 405, and a slide groove 4051 is provided on the positioning groove 4052. The industrial camera 406 is installed in the positioning groove 4052, and a fixing bolt 4061 is installed on the industrial camera 406. The fixing bolt 4061 and the slide groove 4051 cooperate with each other to lock and fix the industrial camera 406. The positioning groove 4052 on the substrate 405 provides a precise installation position for the industrial camera 406, ensuring the accuracy of the position when the camera is installed. This design avoids shooting errors caused by camera position deviation during installation. The direct installation of industrial camera 406 simplifies the installation process and reduces the difficulty of installation. At the same time, the design of positioning groove 4052 makes the camera more stable after installation and less prone to shaking. The slide groove 4051 on the positioning groove 4052 provides convenience for adjusting the camera position. After sliding the camera to a suitable position, it is locked with fixing bolt 4061 to ensure its stable position. This design prevents the camera from loosening due to vibration or external force, and ensures the stability and reliability of shooting. A laser distance sensor 401 is installed on one end face of the substrate 405, and a dispensing head 403 is installed on the end face of the substrate 405 away from the laser distance sensor 401. The cross section of the substrate 405 is trapezoidal, and the laser distance sensor 401 and the dispensing head 403 are respectively installed on the two side end faces of the substrate 405 through the first mounting seat 4011 and the second mounting seat 4031. The trapezoidal cross-section design significantly enhances the overall strength and rigidity of the substrate 405, making it more stable when bearing the weight of the dispensing head 403 and the laser distance sensor 401 and the vibration and impact generated during operation. This stability is crucial to ensure the accuracy of dispensing and laser distance measurement. The trapezoidal design optimizes space utilization and is particularly suitable for compact automated production environments. By installing the laser distance sensor 401 and the dispensing head 403 on both sides of the substrate 405, the mutual interference between the two can be effectively reduced, while leaving sufficient space for their respective operations. This layout also helps to reduce the overall size of the device and improve the integration of the equipment. The dispensing head 403 is provided with two feed interfaces, and the two feed interfaces are connected to the glue and the fluorescent agent through conduits respectively, so that the dispensing head 403 mixes the glue and the fluorescent agent before dispensing, which is convenient for the subsequent detection of the position and coverage of the glue by the fluorescent sensor 404.

[0069] Working principle:

[0070] The motor 103 drives the rotating shaft 506 on the conveyor belt 5 through the first chain 104, thereby driving the entire conveyor belt 5 to move. The workpiece to be dispensed is placed on the conveyor belt 5, and the workpiece moves forward with the conveyor belt 5. The photoelectric sensor 101 detects the time interval between each passing of the identification plate 5022 installed on the second chain 503, thereby calculating the rotation speed of the conveyor belt 5. This information provides a speed reference for subsequent dispensing operations.

[0071] The industrial camera 406 is mounted on the machine head 4, and adjusts its position as the robot arm 3 moves, taking images of the workpiece to be dispensed. These images are transmitted to the control system for further processing. The control system processes the images taken by the industrial camera 406, extracts key information such as the shape and position of the workpiece, and provides a positioning basis for subsequent precise dispensing.

[0072] The laser distance sensor 401 is mounted on the machine head 4 to measure the distance between the machine head 4 and the workpiece to be glued. This information helps to further calibrate the position of the glue dispensing head 403 to ensure the accuracy of glue dispensing.

[0073] The dispensing head 403 is provided with two feed interfaces, which receive glue and fluorescent agent respectively. Before dispensing, the glue and fluorescent agent are mixed evenly inside the dispensing head 403. According to the results of visual recognition and laser ranging, the control system drives the robot arm 3 to move the dispensing head 403 to a precise position and perform the dispensing operation. The addition of fluorescent agent enables the position after dispensing to be detected and confirmed by the fluorescent sensor 404.

[0074] The fluorescence sensor 404 is mounted on the machine head 4 and is used to detect the distribution of the fluorescent agent on the workpiece after dispensing. By detecting the distribution of the fluorescent agent, it can be further confirmed whether the position and coverage of the glue meet the requirements.

[0075] During the entire dispensing process, the control system will record relevant data, such as conveyor belt speed, dispensing position, dispensing amount, etc., for subsequent analysis and optimization. Based on the results of data recording, the control system can adjust the dispensing parameters in real time to ensure the stability and consistency of dispensing quality.

[0076] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
