Detailed Implementation
[0036] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.
[0037] Please refer to Figures 1-4 As shown, an embodiment of this application provides an adhesive coating device, including a workpiece carrier 5, a moving mechanism 4, a vision inspection component 3, and a moving mechanism. The workpiece carrier 5 is disposed on the moving mechanism 4, and the moving mechanism 4 drives the workpiece carrier 5 to move between a first station and a second station. The vision inspection component 3 is disposed on the second station, and the moving mechanism is provided with an adhesive coating device 9 to drive the adhesive coating device 9 to move to the second station for adhesive coating.
[0038] The workpiece carrier 5 is used to place the target workpiece 6 to be coated with adhesive, ensuring that the target workpiece 6 is stably fixed on the workpiece carrier 5. The workpiece carrier 5 can be moved via the moving mechanism 4, allowing switching between the first and second workstations. The first workstation can be a loading station, a unloading station, or a loading and unloading station. Additionally, another unloading station can be set up for unloading; there are no restrictions. The second workstation is the adhesive coating station. By moving between the first and second workstations, the target workpiece 6 to be coated with adhesive can be loaded, unloaded, or loaded and unloaded, thus achieving automatic conveying, which is more convenient and faster. A vision inspection component 3 is installed at the second workstation. The vision inspection component 3 is mainly used for pre-coating image positioning detection and post-coating detection. The pre-coating image positioning detection can be configured to determine whether the workpiece has moved into position and to guide the adhesive coating using coordinates based on the image. The post-coating detection can be configured to take images to detect the thickness and deviation of the adhesive lines to determine whether the adhesive coating is qualified. An adhesive applicator 9 is installed on the movable mechanism. The adhesive applicator 9 can move to the second workstation via the movable mechanism to apply adhesive to the target workpiece 6 at that workstation. Through the cooperation between various mechanisms and devices, the processes of workpiece conveying and adhesive application can be automated, reducing labor costs.
[0039] In the embodiments of this application, the visual detection component 3 mainly includes a visual module 31, a light source component 33, and a driving mechanism 32, wherein the driving mechanism 32 drives the visual module 31 and / or the light source component 33 to switch between a working position and a clearance position.
[0040] The vision module 31 of the vision inspection component 3 is used for photographic inspection, and the light source module is used for photographing and lighting so that the target workpiece 6 to be coated with glue can obtain better lighting effect, thereby enabling the vision module 31 to form a clearer image. The drive mechanism 32 is used to drive the vision module 31 and / or the light source component 33 to switch between the working position and the avoidance position. When the vision module 31 and / or the light source component 33 is in the avoidance position, it can avoid the glue coating activity area and avoid mutual interference.
[0041] In some application scenarios, the driving mechanism 32 can drive the light source component 33 to switch between the working position and the avoidance position. This allows the light source component 33 to avoid obstacles while also moving closer to the target workpiece 6 to provide illumination, enabling the camera component to obtain a clearer image from a fixed position. Alternatively, the driving mechanism 32 can simultaneously drive the vision module 31 and the light source component 33 to switch between the working position and the avoidance position. By moving both the vision module 31 and the light source component 33 simultaneously, a clearer and more accurate image can be obtained, but the positioning of the vision module 31 is more cumbersome. The driving mechanism 32 can also drive only the vision module to switch between the working position and the avoidance position. By moving the vision module 31, a clearer and more accurate image can be obtained, but this can easily obstruct the illumination and the positioning is also more cumbersome. The above driving methods can be selected and configured according to actual needs and are not limited.
[0042] Through the above technical solution, the workpiece to be coated can be placed on the tooling fixture. The tooling fixture can move between the loading / unloading position and the coating position through the moving mechanism 4 to achieve automatic delivery. The light source component 33 of the vision inspection component 3 can switch between the working position and the avoidance position through the drive mechanism 32. When the light source component 33 is in the working position, it can better illuminate the workpiece, which can help the vision module 31 obtain a clearer image, thereby meeting the high imaging quality lighting requirements of the vision module 31. It can also avoid interference with the coating process of the robotic arm 8, which is more conducive to the visual inspection of the coating. At the same time, it can also achieve a higher degree of automation and reduce labor costs.
[0043] In one embodiment, the visual inspection component 3 further includes a lifting guide member 321, the light source component 33 is slidably disposed on the lifting guide member 321, and the driving mechanism 32 drives the light source component 33 to move and switch between a working position and a clearance position along the lifting guide member 321.
[0044] In this way, the light source assembly 33, which is slidably mounted on the lifting guide component 321, can switch between the working position and the avoidance position along the guiding direction of the lifting guide component 321 by the drive mechanism 32. Switching and avoiding in a vertical lifting manner can make better use of the upper space and avoid occupying the horizontal space.
[0045] Furthermore, in combination Figure 4 and Figure 5 As shown, in order to obtain a better lighting effect, the light source assembly 33 includes a mounting frame 331 that is slidably connected to the lifting guide member 321 and multiple sets of light sources arranged on the mounting frame 331 around the vision module 31, and the angle of each set of light sources is adjustable.
[0046] In this way, multiple light sources are arranged around the vision module 31 on the mounting bracket 331, allowing the multiple light sources to illuminate from one side or the same circumference upwards. This avoids obstructing the vision module and enables 360° illumination of the target workpiece 6, which in turn helps the vision module obtain better imaging. At the same time, each light source can be adjusted in angle through a hinged joint with a rotating component 333, which serves as a pivot. This makes it easier to adjust the light source according to different needs, making it more practical and convenient.
[0047] In practical implementation, the lifting guide component 321 includes a driving component 322 and two longitudinally arranged longitudinal guide rails 922. The light source assembly 33 is slidably disposed between the two longitudinal guide rails 922, and is driven to move up and down by the driving component 322, thereby realizing the position switching of the light source. The driving component 322 can be a cylinder or a lead screw and nut pair working with a motor to achieve the drive, and there is no limitation.
[0048] Preferably, the vision module 31 uses four CCD cameras 311 in conjunction with four strip light sources 332.
[0049] In a preferred embodiment of the loading device, combined with Figures 6-8 As shown, the workpiece carrier 5 includes a tooling base 51 and a quick-change tooling 52 disposed on the tooling base 51. The quick-change tooling 52 is provided with a plurality of positioning pins 53 and a plurality of vacuum suction cups 54 for adsorbing workpieces.
[0050] The tooling base 51 is fixedly mounted on the moving mechanism 4, while the quick-change tooling 52 is detachably mounted on the tooling base 51. This facilitates the replacement of the quick-change tooling 52, which can hold different workpieces. Furthermore, the positioning pin 53 and the vacuum suction cup 54 facilitate the placement and fixation of the target workpiece 6.
[0051] Based on this, the top of the tooling base 51 is also provided with a quick-change connector 58, and the bottom of the quick-change tooling 52 is provided with a quick-change connector 57. The quick-change connector 57 is engaged with the quick-change connector 58. The quick-change connector 58 is provided with a connecting shaft, and multiple outwardly protruding steel balls 59 are provided on the periphery of the connecting shaft through the mounting groove. The steel balls 59 can be elastically protruded or compressed back by the spring in the mounting groove. The quick-change connector 57 is provided with a socket for the connecting shaft to be inserted. The periphery of the socket wall is provided with a limiting groove for the steel balls 59 to form a limiting fit in the longitudinal direction after protruding. With this structure of quick-change connector 57 and quick-change connector 58, quick-change can be realized, making it more convenient and faster to use.
[0052] To facilitate the separation of the target workpiece 6 from the vacuum suction cup 54 after adhesive application, the quick-change connecting seat 58 is further provided with a demolding lifting component 56, and the quick-change tooling 52 is provided with an opening 55 for the demolding lifting component 56 to pass through. The demolding lifting component 56 is a lifting cylinder, and the telescopic end of the lifting cylinder passes through the opening 55 to act on the target workpiece 6.
[0053] Please refer to Figures 1-3 As shown in the embodiment of this application, the active mechanism is a robotic arm 8, which is electrically connected to a controller. The moving mechanism 4, vision module 31, light source assembly 33, drive mechanism 32, and glue applicator 9 are all electrically connected to the controller.
[0054] The robotic arm 8 can drive the glue applicator 9 to apply glue to the target workpiece 6 from multiple axes and angles, making the glue application more flexible and convenient. The controller can be a PLC or similar controller, which simultaneously controls the moving mechanism 4, the vision module 31, the light source assembly 33, the drive mechanism 32, and the glue applicator 9. In this way, glue application can be automated through preset execution logic.
[0055] In practical implementation, the controller can also perform functions such as workpiece type and shape recognition and yield detection through the imaging configuration of the vision module 31. Regarding yield detection, the optimal qualified product is used as the benchmark to detect size deviations, shape detection, and glue line thickness detection. Tolerances are added according to process requirements, and the deviation value is calculated visually; anything exceeding these limits is considered unqualified. The above detection methods are existing technology and will not be elaborated upon here.
[0056] In order to clean the glue from the glue outlet 94 of the glue applicator 9, combined with Figure 3 and Figure 9 As shown, the adhesive application equipment may further include an adhesive cleaner 10 located at the third station. The movable mechanism drives the adhesive application device 9 to switch between the second and third stations. After the adhesive application is completed, the movable mechanism can move the adhesive application device 9 to the third station where the adhesive cleaner 10 is located, and the adhesive cleaner 10 can automatically clean the adhesive outlet 94.
[0057] Specifically, the adhesive remover 10 can unwind the adhesive strip via the unwinding wheel 102 and wind it up via the take-up wheel 101. A steering shaft 103 is provided between the unwinding wheel 102 and the take-up wheel 101. The adhesive strip can turn around the steering shaft 103. By providing clamping members 104 on both sides, the two sections of the adhesive strip that have turned around the steering shaft 103 move inward and stick tightly to the adhesive outlet 94, thus achieving automatic adhesive removal and avoiding manual cleaning.
[0058] Please refer to Figures 10-14As shown. In an embodiment of this application, the glue applicator includes a glue pushing assembly 91, a second drive mechanism 92, a valve assembly 93, and a glue dispensing head 94. The glue pushing assembly 91 includes a housing for accommodating a glue stick 95 and a pushing member 911 inserted into the housing. The housing is provided with a disassembly part 914 for loading the glue stick 95. The second drive mechanism 92 drives the pushing member 911 to move axially along the housing. The housing is connected to the glue dispensing head 94 through the valve assembly 93. The housing is provided with a first connection part 915 that communicates with the interior of the housing and is used for introducing gas.
[0059] The adhesive pushing assembly 91 is used to push the adhesive stick 95. The adhesive stick 95 is installed in a housing that can accommodate it. Inside the housing, the adhesive stick 95 is pressurized by the pushing member 911, causing the adhesive inside to be squeezed out and enter the dispensing head 94 through the valve assembly 93 for application. The housing is provided with a disassembly part 914 that allows the housing to be opened, facilitating the insertion and removal of the adhesive stick 95. The disassembly part 914 can be located at the axial end or on the periphery of the housing. Furthermore, the disassembly part 914 can be detachable or a hatch-like installation structure, as long as it allows for the insertion and removal of the adhesive stick 95; there are no limitations. The drive mechanism 92 drives the pushing member 911 to push the adhesive stick 95 axially, causing the adhesive inside the adhesive stick 95 to be squeezed out from the nozzle 953 at the head to the tail. Because the glue stick 95 experiences an imbalance between circumferential and end pressures when compressed within the housing, a first connecting part 915 facilitates connection to a gas injection device. This allows gas to be introduced after connection, increasing internal pressure and maintaining internal pressure balance, thus preventing glue overflow during the dispensing process. In practice, the first connecting part 915 can be a connecting hole on the housing. Specifically, the moving mechanism 4 can be an electric guide rail 922 or a linear mechanism such as a lead screw and nut pair.
[0060] Through the above technical solution, the glue pushing component 91 can be easily loaded and replaced with glue stick 95 through the disassembly part 914. When glue stick 95 is squeezed out by the pushing component 911 pushed by the second drive mechanism 92, it can be pushed to the glue outlet 94 through the valve component 93 to make glue application convenient. After the glue stick 95 is used up, a new glue stick 95 can be loaded by opening the disassembly part 914. It is convenient and quick, and also reduces the complexity and cost of the mechanism. In addition, gas can be easily introduced through the first connecting part 915 to increase the internal air pressure and balance the internal pressure, thereby preventing glue from overflowing at the tail of the glue stick 95, making the glue pushing more stable and smooth.
[0061] In one embodiment, the disassembly portion 914 includes a first end cap 9141 disposed at the end of the housing.
[0062] In this way, by using the first end cap 9141 provided at the end of the housing as a disassembly part 914, the end of the housing can be opened by disassembling and separating it, which facilitates the insertion or removal of the glue stick 95. The connection between the first end cap 9141 and the housing can be a threaded connection or a snap-fit connection, as long as it is convenient to fill the glue stick 95, there is no limitation.
[0063] Furthermore, the housing includes a cylindrical portion 913 and a second end cap 912. The first end cap 9141 and the second end cap 912 are respectively disposed at one end of the cylindrical portion 913. The connecting portion is disposed on the cylindrical portion 913. The pushing member 911 passes through the second end cap 912 and slides with the second end cap 912 through a sliding seal.
[0064] In this way, the two ends of the cylinder 913 are respectively connected to a first end cap 9141 and a second end cap 912. The first end cap 9141 is connected to the valve assembly 93, and the valve assembly 93 can be detached from the housing along with the first end cap 9141. The second end cap 912 allows the pushing member 911 to pass through and simultaneously achieves a sliding seal through a sliding seal, thus ensuring relatively stable internal pressure. Specifically, the sliding seal can be an oil seal bushing 916.
[0065] In order to be compatible with a 95-grade glue stick, combined with Figure 12 and Figure 13 As shown, further, the pushing member 911 includes a rod portion 9111 and a pressure-applying portion 9112 connected to the rod portion 9111, the diameter of the pressure-applying portion 9112 being smaller than the inner diameter of the end cap 952 of the glue rod 95.
[0066] The glue stick 95 is a section with a nozzle 953 and a tail cap 952. The tail cap 952 is fixedly sealed inside the glue stick shell 951, and the tail cap 952 has a cylindrical groove structure. When the pressure part 9112, whose diameter is smaller than the inner diameter of the tail cap 952, applies axial pressure to the tail cap 952, the connection between the tail cap 952 and the cylindrical glue stick shell 951 will be broken. At this time, the tail cap 952 will act as a piston and move axially inside the glue stick shell 951 to squeeze the glue inside. When the tail cap 952 reaches the other end of the glue stick shell 951, the glue will be basically squeezed out, thereby realizing glue pushing. At the same time, after air is introduced through the first connecting part 915, the internal air pressure increases, thus preventing the problem of glue overflow at the tail of this type of glue stick 95 during the extrusion process.
[0067] In the embodiments of this application, the second drive mechanism 92 is a linear drive mechanism, and a pressure sensor 96 is provided between the pushing member 911 and the drive mechanism. The pressure sensor 96 and the linear drive mechanism are electrically connected to a controller (not shown in the figure).
[0068] The linear drive mechanism can drive the pressing component 911 to perform linear motion for linear glue dispensing. The controller can directly acquire or acquire the travel distance of the linear drive mechanism through relevant position sensors. When the travel distance is zero, the glue dispensing is complete. The pressure sensor 96 can be used to detect pressure changes during the pressing process. The pressure parameters fed back by the sensor can facilitate the controller to stop the linear drive mechanism or perform calibration. For example, after loading a new glue stick 95, the position can be calibrated using the force feedback parameters obtained from existing tests. Then, according to the linear travel distance parameter L of the current glue stick 95 obtained from tests, the linear distance change X can be obtained through the acquired linear drive mechanism drive parameters. When LX = 0, the glue dispensing is complete. Of course, the controller can be a controller with certain programmable functions, such as a PLC controller, and there are no restrictions.
[0069] Preferably, the linear drive mechanism is a lead screw and nut pair drive mechanism driven by a servo motor 921, and the servo motor 921 is electrically connected to the controller. The cooperation between the servo motor 921 and the lead screw and nut pair drive mechanism enables more precise driving and facilitates the calculation of the linear distance change X using the parameters of the servo motor 921 and the lead screw, thereby allowing for better control of the glue dispensing amount.
[0070] In a preferred embodiment of the valve assembly 93, combined with Figure 14 As shown, the valve assembly 93 includes a screw valve 933 and a drive motor 932 for driving the screw valve 933. The feed end of the screw valve 933 is connected to the housing through a pipe 97, and the discharge end of the screw valve 933 is connected to the dispensing head 94.
[0071] The drive motor 932 drives the screw valve 933 to operate. The screw valve 933 can transport the glue entering the screw valve 933 to the glue outlet 94 through the pipeline 97. Using the screw valve 933 as a conveying component also allows for precise control of the glue dispensing amount. The first end cap 9141 is also provided with a connecting nozzle for connecting to the pipeline 97.
[0072] Based on this, the drive motor 932 is connected to the controller via an encoder 931. The encoder 931 can easily collect the displacement of the drive motor 932 shaft rotation and generate pulse signals to feed back to the controller, thereby facilitating coordination with the servo motor 921 of the linear drive mechanism to achieve precise control of the glue dispensing amount.
[0073] To facilitate the connection of movable mechanisms such as robotic arm 8 for adhesive application, combined with Figure 10 and Figure 11As shown, it also includes a mounting bracket 910. The adhesive pushing assembly 91, the drive mechanism 92 and the valve assembly 93 are all mounted on the mounting bracket 910. The mounting bracket 910 is provided with a second connecting part 99 for connecting the robotic arm 8.
[0074] The adhesive applicator 91, drive mechanism 92, and valve assembly 93, all mounted on the mounting bracket 910, can move as a unit with the mounting bracket 910. This allows the robotic arm 8, connected to the mounting bracket 910 via the second connecting part 99, to move flexibly, enabling multi-angle adhesive application to the target workpiece 6 or parts, making it more convenient and practical. Specifically, the second connecting part 99 is a connecting plate perpendicularly connected to the mounting bracket 910.
[0075] Specifically, the adhesive pushing assembly 91 and the valve assembly 93 are located on one side of the mounting bracket 910, and the second driving mechanism 92 is located on the other side. The second driving mechanism 92 is connected to the pushing member 911 through the connector 98.
[0076] For better linear drive, the linear drive mechanism also includes a guide rail 922 and a slider 923 slidably mounted on the guide rail 922. The guiding direction of the guide rail 922 is parallel to the moving direction of the pushing member 911, and the slider 923 is connected to a lead screw and nut drive mechanism (not shown in the figure) driven by a servo motor 921. The lead screw and nut drive mechanism is located inside the guide rail 922. Thus, the slider 923 can move linearly under the drive of the servo motor 921. While the slider 923 is moving, the push rod can be driven to move linearly through the connecting member 98, thereby realizing the glue pushing action.
[0077] To achieve better operation and protection, combined with Figure 1 and Figure 2 As shown, the above-mentioned mechanisms are all set on the operating table 1 and protected by the protective cover 2 set on the operating table 1. The protective cover 2 is provided with an operating window, and a light grating 7 is provided in the operating window. When an object extends into or enters the protective cover 2 through the operating window, it can be detected by the light grating 7 and an alarm will be triggered by a device such as a buzzer.
