Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, and more specifically, to a semi-automatic adhesive coating system. Background Technology

[0002] Currently, when using manual glue application equipment, operators must be present throughout the entire process. This includes placing the parts on the application table, applying glue using a glue gun according to the predetermined procedure, returning the glue gun to the table after application, and finally removing the glued parts. Therefore, manual glue application equipment has a high personnel occupancy rate, making labor costs increasingly prominent. Furthermore, because the glue is applied manually, the results are subject to subjective influence, easily leading to over- or under-application, or even misapplication, resulting in unstable production outcomes and ultimately affecting vehicle body quality.

[0003] Currently, adhesive coating equipment is divided into two types: manual adhesive coating equipment and automatic adhesive coating equipment, used in manual and automatic production lines respectively. Due to differences in structure, safety, and service conditions, the two cannot be simply interchanged. Therefore, it is not possible to simply replace manual adhesive coating equipment with automatic adhesive coating equipment in its original location. Automatic adhesive coating equipment has a high degree of automation and its quality stability is significantly better than that of manual adhesive coating equipment. However, it has a complex structure, is expensive, and requires corresponding robots, fixtures, supports, and other equipment. If the manual adhesive coating process is integrated into an automatic line, it would require the addition of automatic adhesive coating equipment and robots, and even numerous other devices such as loading ports, fixtures, and roller shutters, leading to adjustments in the production line layout and high budgets. Furthermore, manual adhesive coating equipment is a fixed asset; scrapping it while it is still in normal service would result in the loss of state-owned assets.

[0004] How to modify manual glue application equipment to enable automated glue application and allow it to be used in its original location is a problem that urgently needs to be solved in manual glue application production lines. Utility Model Content

[0005] To solve at least one of the above-mentioned technical problems, this utility model provides a semi-automatic glue application system, which connects an automatic glue application gun to the end of a robot's robotic arm. The robot moves the automatic glue application gun, and the control module of the automatic glue application gun controls the opening and stopping of glue dispensing, thereby realizing semi-automatic glue application on parts.

[0006] The technical problem solved by this utility model is addressed by the following technical solution:

[0007] A semi-automatic glue application system includes a glue application control cabinet, a pump, an automatic glue application gun, and a robot. The automatic glue application gun is located at the end of the robot's robotic arm, and its glue inlet is connected to the pump's outlet via a glue delivery pipe. The automatic glue application gun has a control module for controlling the opening and closing of the glue application. The pump is electrically connected to the glue application control cabinet, and the control module is electrically connected to the robot's controller.

[0008] Furthermore, the control module includes a solenoid valve, which is installed in the glue dispensing air path of the automatic glue gun. The solenoid valve controls the opening and closing of the glue dispensing from the automatic glue gun, making the control simple and convenient.

[0009] Furthermore, the robot is configured as a six-axis collaborative robot, which allows for flexible setting of the robot's running trajectory.

[0010] Furthermore, the system also includes a glue tank, the inlet of which is connected to the pump. The glue tank contains glue, which is supplied by the pump.

[0011] Furthermore, the system also includes a hose support, which includes a column and a crossbeam. A hose clamp is provided on the crossbeam, and the glue delivery hose is fixedly installed in the hose clamp, suspending the glue delivery hose in the air to facilitate the movement of the glue delivery hose with the automatic glue applicator.

[0012] Furthermore, a slide rail is provided on the crossbeam, and the tube clamp is slidably mounted on the slide rail via a slider, so that the tube clamp can slide along the slide rail to adjust the position of the glue delivery tube.

[0013] Furthermore, a balancer is provided between the tube clamp and the slider to absorb the vibration when the glue delivery tube moves up and down.

[0014] Furthermore, a pressure stabilizing valve is installed on the glue delivery tube to maintain stable glue dispensing from the automatic glue gun.

[0015] Furthermore, the pressure regulating valve is fixed to the hose support by a fixing bracket to support the pressure regulating valve.

[0016] Furthermore, the system also includes a glue application table for placing parts.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) In this semi-automatic gluing system, the operator is only responsible for placing the parts on the gluing table and then controlling the robot to start to complete the gluing. After gluing, the parts can be removed. The gluing process does not need to be accompanied by the gluing process. It can realize semi-automatic gluing of parts. During the robot gluing process, the operator can perform other work, which improves production efficiency.

[0019] (2) The operator is only responsible for starting / stopping the robot. The glue application process is automated by the robot and is not affected by the operator's subjective opinions. Compared with manual glue application equipment, this semi-automatic glue application system has a low personnel occupancy rate, which can reduce the number of operators and reduce costs. The glue application trajectory and glue output are stable, the glue application quality is significantly improved, and the stability is significantly enhanced.

[0020] (3) The semi-automatic glue application system can be modified based on the manual glue application equipment and can still be used in the original station of the manual production line. Compared with the manual glue application equipment, the semi-automatic glue application system has a high degree of automation and low labor cost. Compared with the fully automatic glue application equipment, the semi-automatic glue application system has a simple structure and control program and does not rely on the standard electrical communication environment of the fully automatic production line required by the fully automatic glue application equipment.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments of this disclosure to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0025] In the description of this utility model, it should be noted that the term "comprising" and its variations indicate an open-ended inclusion, that is, "including but not limited to". Furthermore, in the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] This utility model provides a semi-automatic glue application system, such as Figure 1 As shown, the system includes a glue application control cabinet 1, a pump 2, an automatic glue application gun 3, and a robot 4. The automatic glue application gun 3 is located at the end of the robotic arm of the robot 4, and its glue inlet is connected to the outlet of the pump 2 via a glue delivery pipe 5. The automatic glue application gun 3 has a control module, which is used to control the opening and closing of the glue dispensing from the automatic glue application gun 3. The pump 2 is electrically connected to the glue application control cabinet 1, and the control module is electrically connected to the controller of the robot 4.

[0027] The automatic glue applicator 3 is connected to the end of the robotic arm of the robot 4, allowing the robot 4 to move with the automatic glue applicator 3. Preferably, the controller of the robot 4 is a PLC controller. A PLC program is written for the robot 4 based on the glue application location of the part, thereby controlling the movement trajectory of the end of the robot 4, so that the robotic arm of the robot 4 moves the automatic glue applicator 3 along a predetermined trajectory. Glue is pumped out by the pump 2, and the control module of the automatic glue applicator 3 controls the opening and closing of the glue dispensing, achieving semi-automatic glue application to the part. The pump 2 is electrically connected to the glue application control cabinet 1. The opening and closing of the pump 2 can be controlled by the glue application control cabinet 1, and the operating parameters of the pump 2, such as glue delivery temperature and pressure, can also be adjusted and maintained through the glue application control cabinet 1. For example, the glue application control cabinet 1 can be the control cabinet of an SCA 90903.466E00 manual glue applicator, and the pump 2 can be the pneumatic pump of an SCA PPW57-280P08-600 manual glue applicator.

[0028] In some embodiments, the control module includes a solenoid valve 31, which is located in the glue dispensing air path of the automatic glue gun 3. The solenoid valve 31 controls the opening and stopping of glue dispensing from the automatic glue gun 3, making the control simple, convenient, and low-cost. For example, the automatic glue gun 3 can use an SCA AK400-152.5 glue gun. When this semi-automatic glue dispensing system is in use, the pump 2 pumps the glue from the glue tank 6 and delivers it to the automatic glue gun 3 through the glue delivery pipe 5. When the solenoid valve 31 of the automatic glue gun 3 is opened, the glue dispensing air path of the automatic glue gun 3 is opened, and glue is dispensed from the glue outlet to perform the glue dispensing operation on the parts. When the solenoid valve 31 of the automatic glue gun 3 is closed, the glue dispensing air path of the automatic glue gun 3 is closed, and the automatic glue gun 3 stops dispensing glue.

[0029] Solenoid valve 31 is electrically connected to the controller of robot 4. The opening and closing of solenoid valve 31 can be controlled by the PLC controller of robot 4, thereby controlling the opening and closing of automatic glue applicator 3 in accordance with the movement trajectory of robot 4. This allows automatic glue applicator 3 to automatically open at pre-set glue-applying positions and automatically close at positions where glue application is not required, thus completing automated glue application. The opening and closing of automatic glue applicator 3 is not controlled by time but by the movement trajectory points of robot 4, ensuring precise control and accurate glue application. The opening degree of solenoid valve 31, controlled by the PLC controller of robot 4, can also control the glue dispensing amount of automatic glue applicator 3, adapting to the different glue application requirements of different parts and maintaining a stable glue application amount.

[0030] In some embodiments, robot 4 can be a small six-axis collaborative robot, for example, a JAKA C12 robot. The collaborative robot 4 is compact, occupies little space, is easy to deploy, and has low cost. Furthermore, it does not rely on the standard electrical communication environment of traditional fully automated production lines; the robot arm's trajectory can be flexibly set solely through the robot 4's PLC controller, making control simple and convenient.

[0031] In some embodiments, the system further includes a glue tank 6, the inlet of the pump 2 is connected to the glue tank 6, the glue tank 6 stores glue, the inlet of the pump 2 is connected to the glue tank 6, and the glue in the glue tank 6 is pumped out to provide glue to the glue delivery tube 5 and the automatic glue gun 3.

[0032] When the robot 4 moves with the automatic glue applicator 3, the glue delivery tube 5 can be suspended in the air by a glue delivery tube bracket 7 to facilitate its movement. Specifically, the glue delivery tube bracket 7 includes a column 71 and a crossbeam 72. A tube clamp 73 is provided on the crossbeam 72, and the glue delivery tube 5 is fixedly mounted on the tube clamp 73. The glue delivery tube 5 can be supported by the glue delivery tube bracket 7, suspending it in the air and preventing it from falling to the ground. Preferably, multiple tube clamps 73 can be provided along the extension direction of the crossbeam 72 to support multiple positions of the glue delivery tube 5, resulting in more stable support.

[0033] In some embodiments, a slide rail is provided on the crossbeam 72, and the tube clamp 73 is slidably mounted on the slide rail via a slider 74. The tube clamp 73 can slide along the slide rail to adjust the glue delivery tube 5 to a suitable position to match the running trajectory of the robot 4, preventing the glue delivery tube 5 from being dragged or torn during the operation of the robot 4. Preferably, a balancer 75 is provided between the tube clamp 73 and the slider 74, which can absorb the vibration of the glue delivery tube 5 when it moves up and down, and buffer the glue delivery tube 5.

[0034] In some embodiments, a pressure regulating valve 8 is provided on the glue delivery tube 5 to ensure glue delivery pressure, maintain stable glue dispensing from the automatic glue gun 3, and extend the life of the glue delivery tube 5. Since the pressure regulating valve 8 is relatively heavy and the glue delivery tube 5 is suspended in the air, to prevent the pressure regulating valve 8 from falling off the glue delivery tube 5, it can be fixed to the glue tube support 7 by a fixing bracket 9. Specifically, the fixing bracket 9 can be fixed to the crossbeam 72 or the longitudinal beam, providing support for the pressure regulating valve 8, ensuring a secure and reliable connection between the pressure regulating valve 8 and the glue delivery tube 5, and further supporting the glue delivery tube 5.

[0035] In some embodiments, the system further includes a gluing station 10 for placing parts. When the semi-automatic gluing system is in operation, the operator needs to place the parts on the gluing station 10, which can accommodate multiple or various parts. Then, the operator starts the semi-automatic gluing system, and the robot 4 can automatically apply glue along a predetermined trajectory with the automatic glue gun 3.

[0036] When using manual glue application equipment, the operator holds the glue gun throughout the entire glue application process, and the operator manually controls the glue application trajectory, glue gun speed, and glue dispensing volume. In contrast, this semi-automatic glue application system only requires the operator to place the part on the glue application table 10 and then control the robot 4 to complete the glue application. After application, the part can be removed, eliminating the need for continuous operator involvement. While the semi-automatic system is running, the operator can move to other workstations to complete corresponding tasks. Furthermore, the glue application process is automated by the robot 4, unaffected by operator intervention. Therefore, compared to manual glue application equipment, this semi-automatic system has a lower personnel requirement, more stable glue application trajectory and dispensing volume, significantly improved glue quality, and significantly enhanced stability.

[0037] Fully automatic glue application equipment requires a standard electrical communication environment (VASS 5, VASS 6, etc.) for fully automated production lines, working in conjunction with a traditional six-axis industrial robot to complete the fully automated glue application. This semi-automatic glue application system, however, can operate independently without relying on the standard electrical environment of an automated production line. Fully automatic glue application equipment requires a dispensing machine, and the parameters of the pump 2 and the glue application program, such as the glue dispensing volume and time, are adjusted through the glue application control cabinet 1, making control complex. In contrast, the glue application control cabinet 1 of this semi-automatic system does not need to control the glue application program. Instead, it integrates the opening and closing of the automatic glue gun 3 and the glue dispensing volume with the movement trajectory of the robot 4 through the robot 4's PLC controller. The control program is relatively simple, and the matching accuracy between the glue application operation, glue dispensing volume, and glue application trajectory is high.

[0038] This semi-automatic glue application system can be modified from manual glue application equipment. It can retain the main structure of the original manual glue application equipment, such as the glue application control cabinet 1 and pump 2, resulting in a small modification scope, low modification cost, and continued usability on manual production lines. Compared to the original manual glue application equipment, this semi-automatic glue application system offers a high degree of automation and low labor costs. For example, in a project where 12 sets of this system are used in a manual glue application area, an economic assessment shows a saving of 4 people per shift. Based on a single-person labor cost of 162,000 yuan per year, the total labor cost savings over its lifespan (mass production: 7 years) can reach 9.072 million yuan. Using this glue application system can significantly reduce labor costs. Compared to fully automatic glue application equipment, this semi-automatic glue application system has a simpler structure and control program.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
