Description

Technical Field

[0001] This utility model relates to a detection device for preventing leaks and errors in clamps. Background Technology

[0002] Currently, in the manufacturing process of automotive dashboard crossbeams, the scrapping of assemblies and welding damage to tooling due to missing or incorrect parts is a serious problem. Preventing employees from missing or incorrectly assembling parts is a key quality and safety production issue that enterprises are focusing on. Usually, missing or incorrect parts can only be detected through full inspection of the assembly welds and abnormal equipment alarms. This results in high product scrapping costs, long fixture maintenance cycles, and the use of high-precision equipment. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a detection device for preventing omissions and errors in fixtures. This device can reduce the cost of scrapping assemblies and reduce damage to fixtures during production caused by omissions or errors. A sensor position diagram is installed on the human-machine interface. Based on the signals output by the sensors on the fixture, the sensor position diagram can also prompt employees on the clamping sequence, thereby improving production efficiency.

[0004] The technical solution to achieve the above objective is: a detection device for preventing leaks and errors in fixtures, comprising a communicator, a controller, sensors installed at each clamping station of the fixture, and a sensor position diagram installed on the human-machine interface; wherein:

[0005] The sensor communicates with the controller via the communicator;

[0006] The controller is connected to the human-machine interface;

[0007] The sensor signal point distribution in the sensor location diagram corresponds one-to-one with the sensor positions at each clamping station of the fixture.

[0008] In the aforementioned detection device for preventing omissions and errors in clamping, when the sensor detects that a part is properly clamped at the corresponding clamping station, the sensor sends a signal to the controller via a communicator. The controller then controls the clamping fixture to operate and sends the positioning signal to the human-machine interface. The corresponding sensor signal point is displayed normally in the sensor position diagram on the human-machine interface. If a part is missing or not properly clamped, the controller does not receive the feedback signal from the sensor, the clamping fixture will stop at the current step and cannot proceed with the next operation. At the same time, the corresponding sensor signal point is displayed abnormally in the sensor position diagram on the human-machine interface.

[0009] In the aforementioned detection device for preventing leaks and errors in clamps, green indicates that the corresponding sensor signal point is normal, and red indicates that the corresponding sensor is abnormal.

[0010] This utility model discloses a detection device for preventing omissions and errors in fixtures. A sensor position diagram is installed on the human-machine interface. Sensors are used to detect omissions or errors in the fixture during the production process. During the clamping process, the device can detect the presence or absence of parts and convert the output signal to the sensor position diagram to prompt the employee with the clamping sequence. If a part is missing or incorrectly installed, the controller does not receive a signal from the sensor, and the fixture clamping button will be locked, preventing control of the fixture's clamping action. Only when all the parts to be assembled in this step are in place can the fixture receive a signal from the sensor and proceed to the next step. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of a detection device used for preventing leaks and errors in fixtures;

[0012] Figure 2 This is a schematic diagram of the sensors installed at each clamping station of the fixture. Detailed Implementation

[0013] To enable those skilled in the art to better understand the technical solution of this utility model, its specific embodiments are described in detail below with reference to the accompanying drawings:

[0014] Please see Figure 1 and Figure 2 The preferred embodiment of this utility model is a detection device for preventing leakage and errors in fixtures, including a communicator 1, a controller 2, sensors 3 installed at each clamping station of the fixture, and a sensor position diagram 5 installed on the human-machine interface 4; the sensors 3 communicate with the controller 2 through the communicator 1; the controller 2 is connected to the human-machine interface 4.

[0015] In the sensor location diagram 5, the sensor signal points GR01-GR13 correspond one-to-one with the sensor 3 positions on each clamping station of the fixture.

[0016] When sensor 3 detects that a part is properly clamped at the corresponding clamping station, it sends a signal to controller 2 via communicator 1. Controller 2 then controls the fixture to operate and sends the positioning signal to the human-machine interface 4. The corresponding sensor signal points are displayed normally in the sensor position diagram 5 on the human-machine interface 4. If a part is missing or not properly clamped, controller 2 will not receive the sensor feedback signal, and the fixture will stop at the current step, unable to proceed with the next operation. Simultaneously, the corresponding sensor signal points in the sensor position diagram 5 on the human-machine interface 4 will display an abnormality. In sensor position diagram 5, green indicates that the corresponding sensor is normal, and red indicates that the corresponding sensor is abnormal. In this way, the operator can intuitively observe whether each part is missing or not properly clamped in the sensor position diagram 5 on the human-machine interface 4. If parts are missing or incorrectly installed, and the controller does not receive a signal from the sensor, the clamping button will be locked, preventing the clamping action from being controlled. Only when all parts required for this step are properly installed will the controller receive a signal from the sensor and proceed to the next step. This reduces assembly scrap costs and minimizes damage to the clamps caused by missing or incorrect installations during production. The sensor location diagram can also be used to guide employees on the clamping sequence, improving production efficiency.

[0017] In summary, the detection device for preventing omissions and errors in fixtures of this invention can reduce the cost of scrapping assemblies and reduce damage to fixtures during production due to omissions or errors. By installing a sensor position diagram on the human-machine interface, the sensor position diagram can also prompt employees for the clamping sequence based on the signals output by the sensors, thereby improving production efficiency.
