Description

Technical Field

[0001] The utility model relates to a vehicle body fixture installation detection system, which is applicable to the technical field of automobile production detection. Background Art

[0002] As a pre-treatment electrophoresis conveying technology, the body performs a 360° flip when entering and exiting the tank. Due to the many advantages brought by the special structure, it has been widely promoted and applied in domestic and foreign automobile manufacturing paint shops. After the body-in-white enters the painting, the four-door and two-cover fixtures are manually installed, and then it enters the pre-treatment electrophoresis for flipping.

[0003] The car body is turned over in the pre-treatment electrophoresis tank. At present, most automobile OEMs only rely on manual inspection to confirm the installation status of the fixture. If the fixture falls off or becomes loose due to missing or improper installation, it will have the following major impacts on workshop production:

[0004] 1. During the pre-treatment electrophoresis process, if the fixtures used to fix the four doors and two covers are not installed, the doors or covers will open and collide with the equipment in the tank, causing the body parts to be scrapped and the equipment in the tank to be damaged;

[0005] 2. It takes a lot of time to deal with the abnormal fixture body, including the grooving operation and inspection and replacement operation, which seriously affects the normal production flow;

[0006] 3. Currently, the body fixture status inspection is manual inspection, which may cause the risk of missed inspection or incomplete inspection;

[0007] 4. Abnormal fixture installation often leads to production line stoppage and increased production costs. Utility Model Content

[0008] The technical problem to be solved by the utility model is: in order to solve the above technical problem, the utility model provides a vehicle body clamp installation detection system.

[0009] The technical solution adopted by the utility model is: a vehicle body fixture installation detection system, characterized in that: it has:

[0010] A frame is arranged in the inspection station;

[0011] The cover detection module is arranged at a position on the frame corresponding to the cover, and has a first photoelectric switch for obtaining a signal of whether the first photoelectric switch is blocked by the cover;

[0012] The tail cover detection module is arranged at a position on the frame corresponding to the tail cover and has a second photoelectric switch for obtaining a signal of whether the second photoelectric switch is blocked by the cover;

[0013] A door detection module is arranged on the frame at a position corresponding to the door, and is used to obtain distance information between the door detection module and the door;

[0014] The controller, the hood detection module, the tail cover detection module, and the door detection module are all connected to the controller, and the controller can receive the signals of the first photoelectric switch, the second photoelectric switch, and the distance information between the door detection module and the door;

[0015] The alarm module is connected to the controller and is used to alarm and remind personnel when the controller receives a signal that the first photoelectric switch is blocked, a signal that the second photoelectric switch is blocked, or the distance information between the door detection module and the door exceeds the preset range in the controller. In this way, after the body fixture is installed on the body and before the body is transported to the electrophoresis station along the production line, the body is transported to the detection station along the production line. At this time, the door detection module will obtain the distance information between the door detection module and the door, the first photoelectric switch will obtain the signal whether it is blocked by the hood, and the second photoelectric switch will obtain the signal whether it is blocked by the tail cover. When the first photoelectric switch is blocked by the hood, the second photoelectric switch is blocked by the tail cover, or the distance information obtained by the door detection module exceeds the preset range in the controller, the controller will determine that the body fixture is installed abnormally and send a signal to the alarm module. The alarm module will alarm and remind personnel to check the body.

[0016] The alarm module has a hood alarm, a tail cover alarm and a door alarm. The hood alarm is used to alarm and remind personnel when the controller receives a signal that the first photoelectric switch is blocked; the tail cover alarm is used to alarm and remind personnel when the controller receives a signal that the second photoelectric switch is blocked; the door alarm is used to alarm and remind personnel when the controller receives the distance information between the door detection module and the door exceeds the preset range in the controller. In this way, when the hood alarm alarms, it reminds personnel that the hood fixture is installed abnormally; when the tail cover alarm alarms, it reminds personnel that the tail cover fixture is installed abnormally; when the door alarm alarms, it reminds personnel that the door fixture is installed abnormally. It is convenient to remind personnel of the location of the abnormal installation of the fixture, and it is convenient for personnel to further check the abnormally installed fixture.

[0017] The alarm module has a sound alarm and a light alarm, so that personnel can be effectively reminded by the sound alarm and the light alarm.

[0018] The first photoelectric switch has a first laser transmitter and a first laser receiver. When the cover fixture is installed correctly, the first laser receiver will sense the laser emitted by the first laser transmitter. When the cover fixture is not installed or installed incorrectly, the first laser receiver does not sense the laser emitted by the first laser transmitter. In this way, by determining whether the cover blocks the first laser receiver from receiving the laser of the first laser transmitter, it is easy to determine whether the cover is in the position where the cover is when the cover fixture is installed normally.

[0019] The second photoelectric switch has a second laser emitter and a second laser receiver. When the tail cap fixture is installed correctly, the second laser receiver will sense the laser emitted by the second laser emitter. When the tail cap fixture is not installed or is installed incorrectly, the second laser receiver does not sense the laser emitted by the second laser emitter. In this way, by determining whether the tail cap blocks the second laser receiver from receiving the laser of the second laser emitter, it is easy to determine whether the tail cap is in the position where the tail cap is when the tail cap fixture is installed normally.

[0020] The door detection module is a laser rangefinder.

[0021] The first photoelectric switch is slidably mounted on the frame via the first electric slide rail, the second photoelectric switch is slidably mounted on the frame via the second electric slide rail, the door detection module is slidably mounted on the frame via the third electric slide rail, and the first electric slide rail, the second electric slide rail and the third electric slide rail are all connected to the controller. In this way, when the production line is used to produce vehicles of different models, it is convenient to control the operation of the first electric slide rail, the second electric slide rail and the third electric slide rail through the controller to move the first photoelectric switch, the second photoelectric switch and the door detection module to the position corresponding to the body of the vehicle model.

[0022] The beneficial effect of the utility model is as follows: the utility model sets a detection station in front of the electrophoresis station of the automobile production line, and sets a door detection module, a hood detection module and a tail cover detection module in the detection station for detecting whether the door furniture, the hood clamp and the tail cover clamp are installed normally, and when it is detected that the door furniture, the hood clamp or the tail cover clamp is installed abnormally, the controller sends a signal to the alarm module, and the alarm module alarms and reminds personnel to check the vehicle body clamp. In the utility model, the detection of the hood clamp and the tail cover clamp is carried out by photoelectric switch detection, and the first photoelectric switch and the second photoelectric switch are arranged on the frame at positions corresponding to the normal installation of the hood clamp and the tail cover clamp. At this time, the hood clamp and the tail cover clamp are in normal installation, and the first laser receiver of the first photoelectric switch and the second laser receiver of the second photoelectric switch can both receive laser signals; when the hood clamp or the tail cover clamp is installed abnormally, the hood or the tail cover will be displaced and block the first photoelectric switch or the second photoelectric switch, so that the first laser receiver or the second laser receiver does not receive the laser signal, and the controller will determine that the installation of the hood clamp or the tail cover clamp is abnormal and alarm to remind personnel. In this embodiment, the door clamp is detected by a laser rangefinder, and the laser rangefinder is arranged on the frame at a position corresponding to the normal installation of the door clamp. At this time, the distance between the laser rangefinder and the door obtained by the laser rangefinder meets the installation requirements and is within the preset range in the controller; when the door clamp is installed abnormally, the position of the door will change while moving with the production line. At this time, the distance between the laser rangefinder and the door obtained by the laser rangefinder will exceed the preset range in the controller, so that the controller will determine that the door clamp is installed abnormally and alarm to remind personnel.
