Description
Technical Field
The utility model relates to the technical field of gluing of automobile parts, in particular to a gluing detection system.
Background
With the development of automobile manufacturing technology and the continuous improvement of performance thereof, the adhesive seal is used as an important auxiliary material necessary for automobile production, and is increasingly widely applied. In the application of automobile manufacturing, the sealant not only can play roles in reinforcing an automobile structure, fastening rust prevention, heat insulation and vibration reduction and internal and external decoration, but also can replace the traditional processes of welding, riveting and the like of certain parts, realize the connection between the same or different materials, simplify the production process and optimize the product structure. On the roads of automobile light weight, high speed and energy saving, life prolonging and performance improving, the sealant plays an increasingly important role. Because the sealant is usually viscous, the packaging mode is barrel-shaped or branch-shaped, and main technical parameters of the sealant in the use process include the gluing length, the diameter, the position, the validity period, the storage temperature and the like. The quality requirements of the length and the diameter of the sealant are difficult to intuitively control during automatic gluing, and particularly quality defects are easy to generate in an automatic lamination process after the sealant is coated.
In the prior art, a visual detection technology is generally adopted for monitoring the gluing quality, the technology adopts the principle that a camera performs visual photographing, and the difference is fed back by establishing a reference gluing sample to be compared with an actual sample so as to ensure the gluing quality.
However, the detection range of the detection technology has a limitation, usually only a range smaller than 1 square meter can be detected by one camera, when the gluing length of a part is larger than 1 meter, the camera usually needs to move to change the position to detect, during which the part needs to be kept still, and the camera slides to take a picture. In addition, the detection technology needs to scan and photograph in advance, each time the beat is 3-5 seconds, the production time of the station body is occupied, and the production beat is wasted. Therefore, the existing detection technology has higher hardware cost and lower detection efficiency.
Disclosure of utility model
The utility model aims to provide a glue spreading detection system which can solve the technical problems of higher hardware cost and lower detection efficiency of the existing glue spreading detection technology.
In order to achieve the above purpose, the utility model provides a glue coating detection system, which comprises a main controller and a glue coating detection device, wherein two ends of the glue coating detection device are respectively connected with a glue coating gun and the main controller, and the main controller respectively controls actions of a mechanical gripper and the glue coating gun.
As an optimal scheme, the gluing detection device is a laser displacement sensor, the input end of the laser displacement sensor is connected with the gluing gun through an electric signal, and the output end of the laser displacement sensor is connected with the main controller through an electric signal.
Preferably, the laser displacement sensor is arranged on the side face of the glue gun and is positioned above the muzzle of the glue gun.
When the robot grabs a part and starts to glue, a signal is sent out to start the laser displacement sensor to start detection, when the detection is unqualified, the laser displacement sensor feeds back the signal to the main controller, the main controller sends out the signal, and the glue coating equipment stops and gives an alarm. The laser displacement sensor can accurately position the position of unqualified gluing, so that glue supplementing of glue coating equipment is guided. The judging standard for detecting whether the test is qualified is as follows: when the glue coating diameter is changed or glue breaking occurs, the laser displacement sensor cannot receive a distance signal fed back by the glue path, namely the distance signal exceeds the height detection range set by the laser displacement sensor, and the detection is judged to be unqualified at the moment.
As an optimal scheme, the gluing detection device is a current generator and a current receiver, the current generator is connected with the gluing gun, and two ends of the current receiver are respectively connected with the mechanical gripper and the main controller.
Preferably, the current generator and the current receiver are arranged on the gluing device.
Because of the conductivity of the glue, the glue gun, the glue and the mechanical gripper can form a current loop and generate a certain resistance to be fed back to the main controller; when the diameter of the glue is changed, the resistance received by the main controller is also changed; when the glue is spread and broken, the current loop forms a broken circuit, and the main controller receives the broken circuit resistor. According to the scheme, whether the gluing state meets the process requirement is judged by monitoring the resistor formed between the gluing device and the mechanical gripper of the part.
The utility model has the beneficial effects that:
According to the gluing detection system, the gluing detection device is arranged on the gluing gun, so that whether the gluing quality is qualified or not can be detected in real time in the gluing process, the thickness of the glue diameter and the glue breaking state can be rapidly identified, the gluing process can be timely adjusted through the main controller, and the gluing abnormality can be rapidly and accurately fed back. Moreover, the detection system has the advantages of low cost, rapid and convenient detection process, simple equipment maintenance, wide application range and capability of being used in an automatic gluing workstation. Therefore, the utility model can solve the technical problems of higher hardware cost and lower detection efficiency of the traditional glue spreading detection technology.
