Description

Technical Field

[0001] This application belongs to the field of adhesive application technology, and in particular relates to an adhesive application device. Background Technology

[0002] An adhesive coating device is an automated equipment used to precisely apply adhesive to designated areas of a workpiece to achieve functions such as bonding, sealing, moisture protection, insulation, or protection. This device is widely used in the fields of electronic information (such as bonding of circuit board components and adhesive coating for chip packaging), automotive manufacturing (such as sealing of body sheet metal joints and adhesive coating for wire harness fixing), 3C products (such as bonding of mobile phone frames and screens and adhesive coating for laptop shell splicing), medical devices (such as sealing of consumable interfaces and fixing of equipment components), and new energy (such as adhesive coating for battery electrodes and sealing of photovoltaic module frames). Especially in mass production scenarios, the performance of the adhesive coating device is directly related to the product qualification rate and production efficiency.

[0003] However, existing glue coating devices still have many technical shortcomings in practical applications, among which the problem of glue residue is particularly common. After the glue coating operation is completed, glue residue is easily left on the glue dispensing needle, the inner wall of the glue delivery pipeline, or the surface of the glue coating actuator. If this residual glue is not cleaned in time, it will easily cause blockage of the glue dispensing channel after the glue hardens, leading to phenomena such as glue interruption, uneven glue amount, or abnormal trajectory in subsequent glue coating processes. This not only seriously affects the glue coating quality and product consistency and glue coating accuracy, but may also contaminate the surface of the workpiece, increase equipment maintenance costs, and increase production rework rate.

[0042] To provide a clearer understanding of the technical features, objectives, and effects of this application, a detailed description is now provided with reference to the accompanying drawings.

[0045] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, mechanisms, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0046] During the glue application process, the accuracy of the glue application is easily affected by the residual glue on the glue application needle. Furthermore, if the glue application needle remains idle for too long, the glue inside the needle may solidify, leading to poor glue dispensing or even glue interruption. This not only reduces work efficiency but also increases production costs due to the frequent replacement of the glue application needle. Moreover, because high-viscosity glues have poor flowability and dry and solidify faster, these problems are even more pronounced when using high-viscosity glues.

[0047] At least in response to the above-mentioned problems, the present application provides a glue application device in the following embodiments to solve the problems of decreased production efficiency and increased production costs caused by glue residue and glue solidification at the glue application needle during the glue application process of existing glue application devices.

[0048] like Figure 1 As shown, this embodiment provides a glue application device, including a glue application component 1, a glue application robotic arm 2, a weighing component 3, and a glue wiping component 4. The glue application component 1 is used to perform a glue application action on the workpiece to be glued. The glue application component 1 is fixed to the end of the glue application robotic arm 2. The glue application component 1 and the glue application robotic arm 2 work together. The weighing component 3 is used to weigh the amount of glue applied by the glue application component 1. The glue wiping component 4 is used to perform a glue wiping action on the glue application component 1.

[0049] In this embodiment, before applying the adhesive, the adhesive application robot arm 2 moves the adhesive application component 1 to the weighing component 3 to weigh the amount of adhesive applied by the adhesive application component 1, ensuring that the error between the preset amount of adhesive applied by the adhesive application component 1 and the actual amount of adhesive applied does not exceed the preset value; the adhesive application robot arm 2 moves the adhesive application component 1 to the workpiece to be coated and applies the adhesive; after the adhesive application is completed, the adhesive application robot arm 2 moves the adhesive application component 1 to the wiping component 4, and the wiping component 4 wipes away the residual adhesive after the adhesive application by the adhesive application component 1.

[0050] It should be noted that the adhesive application component 1 in the adhesive application device of this application is used to perform adhesive application on the workpiece to be coated. In some embodiments, the adhesive application component 1 includes an adhesive application valve and an adhesive application needle. The amount and shape of adhesive application from the adhesive application needle (such as dot or line) can be adjusted by the adhesive application valve according to process requirements. It is often used in scenarios such as precision electronic component packaging and small structure bonding.

[0051] It should also be noted that the adhesive application robotic arm 2 in the adhesive application device of this application is used to drive the movement of the adhesive application component 1. As an example and not a limitation, the adhesive application robotic arm 2 may include a SCARA robot, a Cartesian coordinate robot, a Delta robot, a cylindrical coordinate robot, or a spherical coordinate robot.

[0052] It should also be noted that the weighing component 3 in the adhesive application device of this application is used to weigh the amount of adhesive applied by the adhesive application component 1. As an example and not a limitation, the weighing component 3 may include an electronic scale, a gravity sensor, a strain gauge weighing module, a piezoelectric weighing sensor, or an electromagnetic force balance weighing device.

[0053] It should also be noted that the adhesive wiping component 4 in the adhesive application device of this application is used to perform an adhesive wiping action on the adhesive application component 1 to clean the residual adhesive left by the adhesive application component 1 before application; for example, the adhesive wiping component 4 may include two sponges, and the residual adhesive of the adhesive application component 1 is wiped away by the relative movement of the two sponges in opposite directions; or, for example, the adhesive wiping component 4 may include two lint-free cloths, and the residual adhesive of the adhesive application component 1 is wiped away by the relative movement between the two lint-free cloths and the adhesive application component 1.

[0054] It should also be noted that the above preset values ​​can be determined according to the coating accuracy required for actual production. In some embodiments, if the error between the preset coating amount and the actual coating amount of the coating component 1 exceeds the preset value, the coating needle and coating valve of the coating component 1 can be cleaned and maintained manually in a timely manner, and the coating amount of the coating component 1 can be corrected and adjusted manually or automatically by the equipment control system of the coating device, so as to control the error within the preset value and ensure coating accuracy.

[0055] In some embodiments, when the error between the preset amount of adhesive applied by the adhesive application component 1 and the actual amount of adhesive applied exceeds a preset value, an alarm signal (such as an audible and visual alarm, a system pop-up window, or a device shutdown command) will be immediately triggered to facilitate timely adjustment.

[0056] This embodiment provides a glue-applying device with functions of weighing and cleaning residual glue, adaptable to glues of various viscosities. Specifically, the weighing component 3 performs quality control on the actual amount of glue applied by the glue-applying component 1, reducing the impact of residual glue from previous applications on the accuracy of the current application; the cleaning component 4 cleans the residual glue from the glue-applying component 1 after the current application, reducing the impact of residual glue from the current application on the accuracy of subsequent applications. This embodiment of the glue-applying device improves application accuracy while reducing rework of the glued workpieces and replacement of the glue-applying needles caused by residual glue, thereby increasing glue-applying production efficiency, reducing waste of raw materials, and lowering production costs.

[0057] Furthermore, the adhesive application device provided in this embodiment, in addition to including the aforementioned adhesive application component 1, adhesive application robotic arm 2, weighing component 3, and adhesive wiping component 4, may also include an adhesive cutting component. The adhesive cutting component is used to cut off the residual adhesive after application by the adhesive application component 1. For adhesives with high viscosity, adhesive stringing may occur after application. The adhesive cutting component can first cut off the stringy adhesive, and then the adhesive wiping component 4 can clean the residual adhesive, further improving the accuracy of adhesive application.

[0058] Furthermore, the glue-applying device provided in this embodiment, in addition to including the aforementioned glue-applying component 1, glue-applying robotic arm 2, weighing component 3, glue-wiping component 4, and glue-cutting component, may also include an anti-coagulation device. The anti-coagulation device is used to prevent the glue-applying component 1 from coagulating. When the glue-applying device has a long standby time, the glue in the glue-applying component 1 may coagulate and block the glue-applying needle. After applying the glue, placing the glue-applying needle of the glue-applying component 1 in the coagulation device can prevent the glue in the glue-applying needle from coagulating during standby. For example, the anti-coagulation device may contain an anti-coagulation medium. By placing the glue-applying needle in the anti-coagulation medium, the glue in the needle tube can be prevented from coagulating. Such as heat-insulating liquid, inert gas, etc., the anti-coagulation function can be achieved by soaking, wrapping, or spraying, avoiding frequent replacement of the glue-applying needle of the glue-applying component 1 and further reducing production costs.

[0059] In some embodiments, the above-mentioned anti-coagulation device may have a built-in constant temperature heating module (e.g., maintaining the temperature below the glue's freezing point) to prevent the glue in the syringe from coagulating; the above-mentioned anti-coagulation device may also prevent the glue in the syringe from coagulating by isolating the glue-applying needle from air. For example, the anti-coagulation device may contain a liquid, and the glue-applying robotic arm 2 drives the glue-applying needle to be immersed in the liquid to isolate it from air. The liquid has the characteristics of not reacting chemically with the glue and not adversely affecting the glue's performance. For example, the liquid may be mineral oil or a special anti-coagulation liquid adapted to the type of glue.

[0060] The following description will further illustrate the adhesive application device provided in this application, taking the aforementioned adhesive application robotic arm 2 as an example, which is a SCARA robot 21 and the adhesive application method.

[0061] like Figure 2 As shown, the adhesive application device provided in this embodiment includes: an adhesive application component 1, a SCARA robot 21, a weighing component 3, an adhesive wiping component 4, an adhesive cutting component 5, an anti-coagulation device 6, and a fixing device 7.

[0062] The following will combine Figures 3 to 7 The structure of each part of the adhesive coating device in this embodiment will be further explained.

[0063] like Figure 3 As shown, the adhesive application assembly 1 includes an adhesive application needle 11 and an adhesive application screw valve 12. The adhesive application needle 11 is used to apply adhesive to the workpiece to be coated, and the adhesive application screw valve 12 is used to control the delivery and distribution of adhesive. The adhesive application needle 11 is fixed to the adhesive outlet at the end of the adhesive application screw valve 12. The adhesive application screw valve 12 is mechanically fixed to the end of the SCARA robot 21. The SCARA robot 21 drives the adhesive application assembly 1 to achieve multi-dimensional and high-precision positional movement to adapt to the adhesive application path requirements of different workpieces.

[0064] like Figure 4 As shown, the weighing component 3 includes an electronic scale 31 and a first bracket 32. The electronic scale 31 is used to weigh the amount of glue applied by the glue application component 1, thereby calibrating the glue dispensing amount of the glue application component 1 and ensuring the glue application accuracy. The first bracket 32 ​​is used to fix the electronic scale 31 so that it is within the movable range of the glue application component 1, which facilitates weighing and verifying the amount of glue dispensed by the glue application needle 11 before glue application.

[0065] like Figure 5 As shown, the adhesive application assembly 4 includes two sets of adhesive application sponges 41, a first container 42, a second support 43, and a drive mechanism 44. The two sets of adhesive application sponges 41 are connected to the drive mechanism 44, which can drive the two sets of adhesive application sponges 41 to move in opposite directions. The first container 42 is detachably fixed to the second support 43, and the drive mechanism 44 is mechanically fixed to the second support 43.

[0066] The two sets of adjacent adhesive-applying sponges 41 form a V-shaped or arc-shaped groove, the size of which matches the diameter of the adhesive-applying needle, ensuring that the two sets of adhesive-applying sponges 41 can closely adhere to the needle surface. Furthermore, the adhesive-applying sponges 41 have high absorbency, effectively removing residual adhesive from the needle. The first container 42 is used to collect adhesive drips during the application process, keeping the working environment clean. The detachable design of the first container 42 facilitates subsequent cleaning of any residual adhesive collected in the container. The second bracket 43 serves as the overall support structure for the adhesive-applying assembly 4. The driving mechanism 44 drives the two sets of adhesive-applying sponges 41 to move towards each other. For example, the driving mechanism 44 may include a miniature cylinder, which can extend (clamp the needle) and retract (release the needle) the adhesive-applying sponges 41, ensuring efficient application.

[0067] In some embodiments, the adhesive wiping assembly 4 may further include a cleaning tank mounted on the second bracket 43. The cleaning tank contains a cleaning solvent, which can automatically extend into the cleaning tank for cleaning after the adhesive wiping sponge 41 has completed multiple adhesive wiping operations, thereby removing residual adhesive adsorbed inside the sponge and extending the service life of the adhesive wiping sponge 41.

[0068] It should be understood that the two sets of adhesive sponges 41 mentioned above can also be replaced with other materials with cleaning capabilities, such as flexible fiber materials (e.g., dust-free wiping cloths and microfiber cloths), elastic rubber or silicone materials, rigid wear-resistant materials (e.g., ceramic scrapers and polytetrafluoroethylene scrapers), etc., without limitation.

[0069] like Figure 5 As shown, the adhesive breaking assembly 5 includes an adhesive breaking wire 51, a fixing seat 52, and a third container 53. The two ends of the adhesive breaking wire 51 are tightened and fixed by the fixing seat 52. The fixing seat 52 is fixed on the second bracket 43. The fixing seats 52 are distributed on both sides of the third container 53. The third container 53 is detachably fixed on the second bracket 43.

[0070] The adhesive-breaking filament 51 is used to cut off the residual adhesive that is pulled into the glue-applying needle 11 before the glue-applying assembly 4 performs the glue-applying action, so as to avoid the residual adhesive from pulling and sticking together and affecting the glue-applying effect; the fixing seat 52 ensures that the adhesive-breaking filament 51 is in a taut state to avoid incomplete glue breaking due to loosening; the second container 52 is used to collect the glue that is cut off during the glue-breaking process, keeping the working environment clean, and the detachable design of the second container 52 makes it convenient to clean the residual glue collected in the container later.

[0071] In some embodiments, the fixing base 52 is provided with a fine-tuning mechanism (such as a threaded knob) for adjusting the tension of the adhesive-breaking wire 51, which can adjust the tension of the metal wire in real time according to the change of adhesive viscosity (such as the need to increase tension when the viscosity increases) to ensure stable adhesive breaking effect.

[0072] In some embodiments, the glue-breaking assembly 5 further includes a position adjustment mechanism for adjusting the position of the glue-breaking filament 51. For example, the position adjustment mechanism is integrated between the fixed base 52 and the second bracket 43, and includes a horizontal adjustment slide rail and a vertical adjustment screw. The horizontal adjustment slide rail allows the fixed base 52 to be adjusted along a direction parallel to the needle movement direction, and the vertical adjustment screw controls the height of the glue-breaking filament 51, ensuring that the glue-breaking filament 51 can be accurately aligned with the glue outlet position of the glue-applying needle 11 to adapt to different specifications of glue-applying needles.

[0073] It should be noted that in this embodiment, the glue-cutting component 5 and the glue-wiping component 4 are integrated and installed on the same bracket, which facilitates the quick removal and cleaning of the residual glue on the glue-applying needle 11 after cutting off the residual glue. The compact layout facilitates efficient collaborative work between the glue-cutting component 5 and the glue-wiping component 4.

[0074] In other embodiments, the adhesive-cutting component 5 and the adhesive-wiping component 4 can also be installed separately, without the need to integrate them together, which facilitates the flexible layout of the adhesive-cutting component 5 and the adhesive-wiping component 4 in the adhesive application device to adapt to different application scenarios.

[0075] By way of example and not limitation, the broken filament 51 may be a metal wire (such as stainless steel wire), a high-strength synthetic fiber filament, a ceramic fiber filament, a nylon filament, etc.

[0076] like Figure 6 As shown, the anti-coagulation device 6 includes a third container 61 and a third support 62. The third container is detachably fixed to the third support 62. The third container 61 can be used to hold liquid. The glue-applying needle 11 is immersed in the liquid to isolate it from the air, prevent the glue in the glue-applying needle 11 from coagulating, and ensure that the glue is always in a flowable state.

[0077] like Figure 7 As shown, the fixing device 7 includes a clamping head 71 and a driving mechanism 72. The clamping head 71 is connected to the driving mechanism 72 and moves along the positioning guide component under the drive of the power component.

[0078] The clamping head 71 is used to pre-press and fix the workpiece to be coated with glue, so that the workpiece to be coated with glue maintains a stable position and state during the glue coating process, ensuring the accuracy and consistency of glue coating; the driving mechanism 72 provides power to the clamping head 71, such as the driving mechanism 72 including a cylinder, electric cylinder, etc.

[0079] The following will further explain the glue-applying device in conjunction with the actual operation process of a glue-applying device in this embodiment.

[0080] S1: Loading and positioning the product to be coated. The product to be coated is moved to the preset positioning station of the coating device to provide a precise positional reference for subsequent fixing and coating operations. This can be achieved through precise placement by manual means or automated gripping by a robotic arm.

[0081] S2: Pre-pressing and fixing the product to be coated with adhesive. The clamping head 71 of the fixing device 7, driven by the driving mechanism 72, firmly fixes the product to be coated with adhesive in a preset position, preventing the product from shifting or shaking during the subsequent adhesive coating process and ensuring the adhesive coating accuracy.

[0082] S3: Take the glue-applying needle 11. The SCARA robot 21 moves the glue-applying needle 11 and removes it from the third container 61 of the anti-coagulation device 6, preparing it for the pre-applying inspection.

[0083] S4: Perform an initial check on the amount of adhesive applied by the dispensing needle 11. The SCARA robot 21, carrying the dispensing assembly 1, arrives above the electronic scale 31 and performs the dispensing operation along a pre-planned trajectory on the weighing platform of the electronic scale 31. After the dispensing is completed, the electronic scale 31 collects the weight data of this dispensing operation and feeds the weight data back to the equipment control system of the dispensing device. If the error between the weight data and the amount of adhesive applied preset by the equipment control system does not exceed the preset value, the dispensing operation continues. If it exceeds the preset value, the amount of adhesive dispensed by the dispensing assembly 1 is corrected and adjusted manually or automatically by the equipment control system (such as adjusting the dispensing pressure and speed of the dispensing screw valve 12), or the dispensing needle and dispensing valve of the dispensing assembly 1 are cleaned and maintained manually in a timely manner until the error is controlled within the preset value, and then the dispensing operation continues.

[0084] In some embodiments, if the error between the weight data and the amount of adhesive applied preset by the equipment control system exceeds a preset value, an alarm signal (such as an audible and visual alarm, a system pop-up window, or an equipment shutdown command) will be immediately triggered to facilitate timely adjustment.

[0085] S5: Perform glue cutting and wiping treatment on the residual glue on the glue application needle 11. Before formal glue application, the SCARA robot 21 moves the glue application needle 11 to above the glue cutting component 5, controls the glue application needle 11 to approach the glue cutting filament 51, and cuts the residual glue filament at the end of the needle by a small movement of the SCARA robot 21 or by the active triggering of the glue cutting filament 51; after the glue cutting is completed, the SCARA robot 21 continues to move the glue application needle 11 to the groove between the two sets of glue wiping sponges 41 of the glue wiping component 4, and wipes the outer wall and end of the needle to thoroughly remove the residual glue, prevent residual glue from contaminating the subsequent glue-to-be-applied products or affecting the glue application quality, and keep the working environment clean.

[0086] S6: The adhesive application needle 11 performs formal adhesive application on the product to be coated. The SCARA robot 21 drives the adhesive application needle 11 to move precisely above the product to be coated, and applies adhesive evenly to the designated area of ​​the product to be coated according to preset adhesive parameters (such as adhesive dispensing amount, adhesive speed, path trajectory, etc.), thus completing the formal adhesive application operation.

[0087] It should be noted that if it is necessary to continue applying glue to the next workpiece, steps one through five above can be repeated until the glue application is completed. Optionally, step S4 can be performed when applying glue to each workpiece, or it can be performed at a preset time or based on the number of workpieces to be glued. For example, after the glue application begins, step S4 can be performed every 30 minutes, or step S4 can be performed after applying glue to 100 workpieces.

[0088] If the adhesive application device needs to remain idle for an extended period after application, the above-mentioned workflow may further include:

[0089] S7: Perform anti-coagulation treatment on the glue application needle 11. The SCARA robot 21 moves the glue application needle 11 to the anti-coagulation device 6 and puts the glue application needle 11 back into the third container 61 of the anti-coagulation device 6 to prevent the glue in the needle from solidifying due to prolonged standing, and to ensure that the glue application needle 11 can dispense glue normally when used next time.

[0090] The glue application device in this embodiment includes the weighing component 3, the glue-cutting component 5, the glue-wiping component 4, and the anti-coagulation device 6. The weighing component 3 controls the amount of glue applied. The glue-cutting component 5 and the glue-wiping component 4 ensure the removal of residual glue of different viscosities, are compatible with glue of different viscosities, and improve the consistency of glue application. The anti-coagulation device 6 ensures the normal glue dispensing of the glue application needle 11 and improves the service life of the glue application needle 11. In addition, the glue application device has a high degree of automation and is very convenient to control and adjust.

[0091] It should be noted that the glue application component 1, the SCARA robot 21, the weighing component 3, the glue wiping component 4, the glue cutting component 5, the anti-coagulation device 6, and the fixing device 7 in the glue application device provided in this application can all be integrated and installed on a single equipment frame, or they can be partially integrated and installed on a single equipment frame, or they can be installed separately. No limitation is made here.

[0092] In summary, the glue application device provided in this application has the functions of weighing the amount of glue applied, cutting off and wiping the glue from the glue application needle, and preventing the glue from solidifying at the glue application needle. This solves the problems of inconsistent glue application amounts and glue solidification at the needle caused by glue residue during application. The device can control the amount of glue applied, is suitable for glues of different viscosities, and can completely remove even high-viscosity glues. It also avoids frequent replacement of the glue application needle due to glue solidification, improving production efficiency and reducing production costs.
