Description

Technical Field

[0001] This utility model relates to the field of glue dispensing technology, and in particular to an automatic glue dispensing device. Background Technology

[0002] Automatic glue dispensing equipment is a widely used automated device in the electronics, electrical appliances, and automotive parts industries, capable of automatically dispensing glue to specific parts of workpieces. Automatic glue dispensing equipment typically includes a glue dispensing mechanism and a robotic arm. The dispensing mechanism stores and dispenses a measured amount of glue, while the robotic arm drives the dispensing mechanism to the designated dispensing station and adjusts its posture to fit the glued area of ​​the workpiece. In existing technologies, the setting and adjustment of the glue dispensing amount rely entirely on the operator's manual experience, lacking quantifiable real-time monitoring and feedback methods. Before applying glue to the workpiece, the operator first starts the equipment for a test application. After a small amount of glue is applied to the waste material board, the operation is paused. The operator observes the coverage and accumulation of glue on the waste material board, and, based on past experience, judges whether the current glue dispensing mechanism is too much or too little. Then, the operator manually operates the parameter buttons on the dispensing mechanism to adjust the glue dispensing volume. After adjustment, the equipment is started again for a test application, and the above observation, judgment, and adjustment are repeated until the glue dispensing volume is visually confirmed to meet expectations. Finally, the glue dispensing parameters are determined, and the equipment is put into batch glue application. This method of adjusting the glue dispensing volume through visual observation and experience is easily affected by the operator's subjective bias, making it difficult to guarantee the accuracy of the glue dispensing volume and thus hindering the improvement of the glue dispensing effect of the automatic glue dispensing equipment. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an automatic glue-dispensing device, which is beneficial for improving the glue-dispensing effect of the automatic glue-dispensing device.

[0004] An automatic glue dispensing device according to an embodiment of the present invention includes a frame, a robotic arm, and a glue dispensing mechanism. The robotic arm is mounted on the frame, and its output end is connected to the glue dispensing mechanism. The device also includes a bracket mounted on the frame, with a mounting plate and a limiting hole on the mounting plate; a weighing device mounted on the frame, positioned below the mounting plate; and a receiving cylinder passing through the limiting hole. The receiving cylinder collects the glue dispensing mechanism's output glue, with its lower end abutting against the weighing device. The weighing device weighs the receiving cylinder and the glue within it.

[0005] It has at least the following beneficial effects: Before applying adhesive to the workpiece, the operator first starts the automatic adhesive dispensing equipment for a trial dispensing. The robotic arm drives the dispensing mechanism to move above the receiving cylinder and starts dispensing adhesive. The dispensing mechanism stops after a set time. During dispensing, all the adhesive discharged falls into the receiving cylinder, allowing the weighing device to weigh the cylinder in real time. After dispensing stops, the operator uses the change in adhesive weight displayed on the weighing device—the total weight of adhesive collected per unit time—to directly determine the dispensing volume per unit time. Based on this dispensing volume data, the operator judges whether the current dispensing volume meets expectations. If not, the parameters of the dispensing mechanism are adjusted, and the dispensing and weighing process is repeated until the dispensing volume per unit time meets expectations. This automatic glue dispensing equipment adjusts the glue dispensing amount per unit time by weighing and detecting, replacing the existing technology that relies on operators to visually observe the state of the glue on the waste board and make judgments based on experience. This effectively avoids the impact of operators' subjective bias on the glue dispensing amount judgment, ensuring the accuracy of the glue dispensing amount of the glue dispensing mechanism. In turn, it ensures the consistency of glue dispensing amount for each workpiece in subsequent batch glue dispensing operations of the automatic glue dispensing equipment, thus improving the glue dispensing effect of the automatic glue dispensing equipment.

Detailed Implementation

[0017] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] refer to Figures 1 to 3 This utility model discloses an automatic glue dispensing device, including a frame 100, a robot arm 500, a glue dispensing mechanism 400, a support 110, a weighing device 140, and a receiving cylinder 130. The robot arm 500 is mounted on the frame 100, and its output end is connected to the glue dispensing mechanism 400. The support 110 is mounted on the frame 100 and has a mounting plate 120 with a limiting hole 121. The weighing device 140 is mounted on the frame 100 and is positioned below the mounting plate 120. The receiving cylinder 130 passes through the limiting hole 121 and is used to collect the glue output by the glue dispensing mechanism 400. The lower end of the receiving cylinder 130 is in contact with the weighing device 140, which is used to weigh the receiving cylinder 130 and the glue inside it.

[0021] Understandably, before applying glue to the workpiece, the operator first starts the automatic glue-applying equipment for a trial application. The robotic arm 500 drives the glue dispensing mechanism 400 to move above the receiving cylinder 130 and starts dispensing glue. The dispensing mechanism 400 stops after running for a set time. During the glue dispensing process, all the glue output by the dispensing mechanism 400 falls into the receiving cylinder 130, allowing the weighing device 140 to weigh the receiving cylinder 130 in real time. After the dispensing mechanism 400 stops dispensing glue, the operator directly calculates the glue dispensing volume per unit time based on the change in glue weight displayed on the weighing device 140, i.e., the total weight of glue collected per unit time. The operator uses the dispensing data to determine if the dispensing volume of the dispensing mechanism 400 meets expectations. If not, the parameters of the dispensing mechanism 400 are adjusted, and the dispensing and weighing process is repeated until the dispensing volume meets expectations. This automatic dispensing equipment adjusts the dispensing volume of the dispensing mechanism 400 by weighing, replacing the existing method of relying on operator visual observation of the glue condition on waste boards and experience. This effectively avoids the impact of operator subjectivity on dispensing volume judgment, ensuring the accuracy of the dispensing volume and thus guaranteeing the consistency of glue dispensing volume for each workpiece in subsequent batch dispensing operations. Therefore, it improves the dispensing effect of the automatic dispensing equipment.

[0022] It should be explained that the weighing device 140 is equipped with a display screen, which can display the weighing data in real time, allowing operators to intuitively read the weight changes of the adhesive in the receiving cylinder 130. Before each dispensing operation of the dispensing mechanism 400, the operator must zero the weighing device 140. After the dispensing mechanism 400 dispenses adhesive according to the unit time and stops, the weight data displayed on the weighing device 140's display screen is the total weight of the adhesive collected within the unit time. This data is directly used to calculate the dispensing volume of the dispensing mechanism 400 within the unit time, effectively avoiding detection errors caused by the weight of the receiving cylinder 130 itself and the weight of residual adhesive. This ensures a consistent benchmark for each dispensing volume data and further improves the accuracy of judging and adjusting the dispensing volume. In a preferred embodiment of this utility model, the unit time is 5 seconds, and the weighing device 140 can be a common electronic scale. In this embodiment of the utility model, the outer wall of the receiving cylinder 130 abuts against the wall of the limiting hole 121. The wall of the limiting hole 121 plays a limiting role in the receiving cylinder 130, effectively preventing the receiving cylinder 130 from shifting horizontally during the trial filling process due to external forces such as slight vibration of the automatic glue dispensing equipment and impact of glue. This not only ensures that all the glue output by the glue dispensing mechanism 400 can fall into the receiving cylinder 130, but also ensures the weighing accuracy of the weighing device 140.

[0023] refer to Figure 3 and Figure 4 The automatic glue dispensing equipment also includes a waste cylinder 260 and a glue scraping mechanism 200. Both the waste cylinder 260 and the glue scraping mechanism 200 are mounted on the mounting plate 120. The glue dispensing end 410 of the glue dispensing mechanism 400 can scrape the glue scraping mechanism 200 so that the glue adhering to the glue dispensing end 410 of the glue dispensing mechanism 400 is transferred to the glue scraping mechanism 200. The waste cylinder 260 is used to collect the glue dripping from the glue scraping mechanism 200. Understandably, during the trial filling phase (such as when weighing and testing the material receiving cylinder 130) or during the intervals of batch glue filling operations on workpieces, when it is necessary to clean the residual glue adhering to the glue dispensing end 410 of the glue dispensing mechanism 400, the robot arm 500 will drive the glue dispensing mechanism 400 to move to the glue scraping mechanism 200 on the mounting plate 120, so that the glue dispensing end 410 of the glue dispensing mechanism 400 makes scraping contact with the glue scraping mechanism 200, so that the glue adhering to the glue dispensing end 410 is peeled off and transferred to the glue scraping mechanism 200 through the scraping action. Subsequently, the glue on the glue scraping mechanism 200 will drip naturally under the action of gravity, and the dripping glue will fall into the waste cylinder 260 below the glue scraping mechanism 200 to complete the collection of residual glue. The scraping mechanism 200 cleans residual adhesive from the dispensing end 410 of the dispensing mechanism 400, preventing the cured adhesive from clogging the dispensing end 410 and ensuring smooth dispensing. It also prevents residual adhesive from mixing with new adhesive during the next dispensing cycle, thus avoiding discrepancies in dispensing volume detection. Furthermore, the waste container 260 collects the scraped-off adhesive, effectively preventing it from dripping and contaminating the operating environment of the automatic dispensing equipment.

[0024] refer to Figure 4 The adhesive scraping mechanism 200 includes an adhesive scraping rope 210. The dispensing end 410 of the dispensing mechanism 400 can scrape the adhesive scraping rope 210 to transfer the adhesive adhering to the dispensing end 410 of the dispensing mechanism 400 onto the adhesive scraping rope 210. It is understood that the adhesive scraping rope 210 has a certain degree of flexibility, allowing it to better conform to the surface of the dispensing end 410 of the dispensing mechanism 400 when scraping, thus achieving efficient removal of residual adhesive. Furthermore, the flexible material of the adhesive scraping rope 210 avoids causing hard wear to the dispensing end 410 of the dispensing mechanism 400 during the scraping process, thereby extending the service life of the dispensing mechanism 400.

[0025] refer to Figure 4The scraping mechanism 200 also includes an unwinding rod 220 and a winding rod 230. The lower ends of both the unwinding rod 220 and the winding rod 230 are rotatably connected to the mounting plate 120. The unwinding rod 220 and the winding rod 230 are respectively located on both sides of the waste cylinder 260. Both ends of the scraping rope 210 are connected to the unwinding rod 220 and the winding rod 230, respectively. Both the unwinding rod 220 and the winding rod 230 are used for winding the scraping rope 210. The unwinding rod 220 can release the scraping rope 210, and the winding rod 230 can wind the scraping rope 210. It can be understood that one end of the scraping rope 210 is wound around the unwinding rod 220 on one side of the waste cylinder 260, and the other end of the scraping rope 210 is wound around the winding rod 230 on the other side of the waste cylinder 260, so that the scraping rope 210 is in a taut state. When it is necessary to clean the residual adhesive at the dispensing end 410 of the dispensing mechanism 400, the operator first rotates the unwinding rod 220 to release part of the scraping rope 210, and simultaneously rotates the rewinding rod 230 to rewind the corresponding length of the scraping rope 210, so that the clean section of the scraping rope 210 without adhesive is moved above the waste container 260. Then, the robotic arm 500 drives the dispensing end 410 of the dispensing mechanism 400 to scrape the clean section on the scraping rope 210 to transfer the residual adhesive. After scraping is completed, if the section of the scraping rope 210 above the waste container 260 has a lot of adhesive attached, the unwinding rod 220 and the rewinding rod 230 can be rotated again to replace the clean section of the scraping rope 210 for the next scraping. The cooperation between the unwinding rod 220 and the rewinding rod 230 enables the section replacement of the scraper rope 210, preventing a decrease in cleaning effectiveness due to excessive localized adhesive residue on the scraper rope 210. This ensures the cleanliness of the contact area between the scraper rope 210 and the dispensing end 410, achieving efficient removal of residual adhesive by the scraper rope 210 and preventing residual adhesive from being transferred back to the dispensing end 410 of the dispensing mechanism 400. (Reference) Figure 4 Both the unwinding rod 220 and the rewinding rod 230 are equipped with a gripping part 240 at their upper ends. The operator can rotate the unwinding rod 220 and the rewinding rod 230 through the gripping part 240, which improves the convenience for the operator to rotate the unwinding rod 220 and the rewinding rod 230.

[0026] In one embodiment of this utility model, damping rings made of elastic rubber are fitted onto the outer walls of the lower ends of both the unwinding rod 220 and the winding rod 230. The mounting plate 120 has two mounting holes. The lower ends of the unwinding rod 220 and the winding rod 230 are rotatably connected to the inner bottom walls of the two mounting holes. Annular grooves are provided on the inner side walls of both mounting holes. The two damping rings are respectively disposed within the two mounting holes and engaged within the two annular grooves. Both the unwinding rod 220 and the winding rod 230 can rotate relative to the damping rings. In a natural state and during scraping, the static friction between the outer walls of the unwinding rod 220 and the winding rod 230 and the inner walls of the two damping rings restricts the free rotation of the unwinding rod 220 and the winding rod 230, ensuring that the unwinding rod 220 and the winding rod 230 will not rotate during scraping. When it is necessary to adjust a section of the scraper rope 210, the operator only needs to apply a torque greater than the static friction force to rotate the unwinding rod 220 and the winding rod 230. The unwinding rod 220 and the winding rod 230 can then rotate over the friction force of the damping ring. After the unwinding rod 220 and the winding rod 230 have rotated, the operator removes the external force. The static friction force between the damping ring and the unwinding rod 220 and the winding rod 230 will immediately limit the continued rotation of the unwinding rod 220 and the winding rod 230, thus completing the fixation of the unwinding rod 220 and the winding rod 230.

[0027] refer to Figure 4 The adhesive scraping mechanism 200 also includes two mounting sleeves 250, the lower ends of which are connected to the mounting plate 120. The unwinding rod 220 and the rewinding rod 230 are respectively located within the two mounting sleeves 250. Each mounting sleeve 250 has a rope passage hole for the adhesive scraping rope 210 to pass through. It is understood that the adhesive scraping rope 210 passes through the rope passage holes on the two mounting sleeves 250, and these holes limit the movement of the rope, ensuring that the portion of the rope 210 between the unwinding rod 220 and the rewinding rod 230 remains straight under tension. On the other hand, during the process of unwinding the rope by the unwinding rod 220 and winding the scraping rope 210 by the winding rod 230, the wall of the rope hole can guide and limit the scraping rope 210, preventing the scraping rope 210 from shaking due to equipment vibration during unwinding and winding, and ensuring that the glue outlet end 410 of the glue outlet mechanism 400 can smoothly scrape against the scraping rope 210.

[0028] refer to Figure 3 and Figure 4The automatic glue dispensing equipment also includes a cleaning mechanism 300, which is mounted on the mounting plate 120. The cleaning mechanism 300 is used to clean the dispensing end 410 of the glue dispensing mechanism 400. Understandably, during trial dispensing, during breaks in batch glue dispensing operations, or after completion, the robotic arm 500 can drive the glue dispensing mechanism 400 to the cleaning mechanism 300 on the mounting plate 120, allowing the cleaning mechanism 300 to clean the dispensing end 410 of the glue dispensing mechanism 400 to remove residual glue. The cleaning mechanism 300 further improves the cleanliness of the dispensing end 410 of the glue dispensing mechanism 400, preventing residual glue from mixing with new glue and causing fluctuations in the glue dispensing volume of the glue dispensing mechanism 400, ensuring the accuracy of the glue dispensing volume, and thus improving the glue dispensing effect of the automatic glue dispensing equipment.

[0029] refer to Figure 4 The cleaning mechanism 300 includes a cleaning box 310 and an ultrasonic generator. The cleaning box 310 is mounted on the mounting plate 120 and is used to hold cleaning fluid. The dispensing end 410 of the dispensing mechanism 400 can be immersed in the cleaning fluid in the cleaning box 310. The ultrasonic generator is mounted on the cleaning box 310. Understandably, when cleaning the dispensing end 410 of the glue dispensing mechanism 400 is required, the robotic arm 500 drives the glue dispensing mechanism 400 to move directly above the cleaning box 310 and controls the glue dispensing mechanism 400 to descend, so that the dispensing end 410 of the glue dispensing mechanism 400 is completely immersed in the cleaning liquid in the cleaning box 310. Then, the ultrasonic generator installed on the cleaning box 310 is activated, and the high-frequency vibration generated by the ultrasonic generator is transmitted to the cleaning liquid, causing a large number of microbubbles to form inside the cleaning liquid, so as to completely peel off the glue residue attached to the dispensing end 410 of the glue dispensing mechanism 400 that was not cleaned by the glue scraping mechanism 200, thereby achieving a thorough cleaning of the dispensing end 410 of the glue dispensing mechanism 400. In this embodiment of the present invention, the cleaning mechanism 300 also includes a blower mechanism, which is mounted on the mounting plate 120 and located next to the cleaning box 310. After cleaning the dispensing end 410 of the dispensing mechanism 400, the robotic arm 500 drives the dispensing mechanism 400 to rise, causing the dispensing end 410 of the dispensing mechanism 400 to be extracted from the cleaning fluid. Then, the blower mechanism is activated to blow and dry the dispensing end 410 of the dispensing mechanism 400, preventing cleaning fluid residue from affecting the normal dispensing of glue by the dispensing mechanism 400. In this embodiment of the invention, the cleaning fluid can be common water or isopropyl alcohol cleaning fluid, and the ultrasonic generator is also a common setting in the cleaning field, which will not be further described here.

[0030] refer to Figure 3 and Figure 4The cleaning mechanism 300 also includes a brush plate 320, which is mounted on the cleaning box 310 and is used to scrape against the dispensing end 410 of the dispensing mechanism 400. Understandably, during ultrasonic cleaning of the dispensing end 410 of the dispensing mechanism 400 immersed in the cleaning fluid within the cleaning box 310, the robotic arm 500 can drive the dispensing mechanism 400 upwards, causing the dispensing end 410 to scrape against the brush plate 320. The bristles of the brush plate 320 can peel off any remaining adhesive residue adhering to the surface of the dispensing end 410 through scraping. Then, the robotic arm 500 can drive the dispensing mechanism 400 downwards, causing the dispensing end 410 to re-immerse in the cleaning fluid. This process is repeated, utilizing the combined action of brush scraping and ultrasonic cleaning to achieve efficient cleaning of the dispensing end 410 of the dispensing mechanism 400.

[0031] refer to Figure 1 The automatic glue dispensing equipment also includes a conveying mechanism 600 and a positioning fixture 610. The conveying mechanism 600 is mounted on the frame 100. The output end of the conveying mechanism 600 is connected to the positioning fixture 610. The conveying mechanism 600 is used to drive the positioning fixture 610 to move in the horizontal direction. The positioning fixture 610 is used to position the workpiece. After the trial filling is completed and the dispensing volume of the dispensing mechanism 400 is adjusted, the unloading robot in the upstream equipment of the automatic dispensing equipment places the workpiece to be dispensed onto the positioning fixture 610, which positions and fixes the workpiece. Then, the conveying mechanism 600 starts, driving the positioning fixture 610 to move horizontally, conveying the fixture and workpiece to the preset dispensing area. Afterward, the conveying mechanism 600 stops. Next, the robot 500, according to the preset dispensing path, drives the dispensing mechanism 400 to move above the dispensing position of the workpiece, aligning the dispensing end 410 of the dispensing mechanism 400 with the dispensing area of ​​the workpiece. The dispensing mechanism 400 then starts and performs the dispensing operation according to the set dispensing volume and speed. During the dispensing process, the robot 500 drives the dispensing mechanism 400 along the preset path to ensure that the adhesive evenly covers the dispensing area of ​​the workpiece. After the glue dispensing operation is completed, the glue dispensing mechanism 400 stops dispensing glue, and the robot arm 500 drives the glue dispensing mechanism 400 away from the glue dispensing operation area. Finally, the conveying mechanism 600 restarts, driving the positioning fixture 610 and the glued workpiece away from the glue dispensing operation area. The material handling robot arm in the downstream equipment of the automatic glue dispensing equipment removes the workpiece from the positioning fixture 610. In this embodiment of the utility model, the conveying mechanism 600 can be a common belt conveyor, and the robot arm 500 can be a common multi-axis robot arm 500. The multi-axis robot arm 500 can drive the glue dispensing mechanism 400 to move in the up-down, left-right, and front-back directions. The glue dispensing mechanism 400 and the positioning fixture 610 are also common settings in the glue dispensing field, and will not be described further here.

[0032] refer to Figure 3 and Figure 4 The automatic dispensing equipment also includes a detection mechanism 700, which is mounted on the mounting plate 120 and includes a laser displacement sensor. Understandably, before the dispensing operation, the robotic arm 500 drives the dispensing end 410 of the dispensing mechanism 400 to the detection mechanism 700. The laser displacement sensor detects the distance to the reference surface of the dispensing end 410 and compares the measured data with a preset standard value to calculate the positional deviation of the dispensing end 410 of the dispensing mechanism 400 in the X, Y, and Z axis directions. If the deviation is within the acceptable range, it is deemed acceptable, and the robotic arm 500 drives the dispensing mechanism 400 into the dispensing area for the dispensing operation. If the deviation exceeds the acceptable range, the operator adjusts the dispensing end 410 of the dispensing mechanism 400 to ensure accurate positioning, thus guaranteeing precise dispensing positioning of the dispensing mechanism 400 subsequently. The detection mechanism 700 is a common distance measuring and detection mechanism 700 used in automatic glue dispensing equipment to calibrate the glue dispensing mechanism 400's dispensing position, and will not be described further here.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
