Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0026] Embodiment 1:

[0027] The utility model provides an automatic quality inspection system for the automatic windshield wiper function of a vehicle. Figure 1 As shown, the automated quality inspection system for the vehicle automatic wiper function includes a vehicle conveying device 1, a rain simulation device 2, a wiper working condition collection device 3 and a control device 4.

[0028] The vehicle conveying device 1 is used for conveying vehicles to be inspected. The rainwater simulation device 2 is arranged above the vehicle conveying device 1 and can spray clean water to the vehicle to be inspected. The wiper working condition collection device 3 is electrically connected to the control device 4.

[0029] During quality inspection, the vehicle conveying device 1 drives the vehicle to be inspected to move and conveys it to the rainwater simulation device 2. The rainwater simulation device 2 sprays clean water to the vehicle to be inspected. At this time, the automatic wiper function of the vehicle to be inspected is triggered and starts to work. During this process, the wiper working condition collection device 3 collects the working condition information of the wiper of the vehicle to be inspected in real time and transmits it to the control device 4. The control device 4 determines whether the wiper of the vehicle to be inspected is working normally based on the working condition information.

[0030] The vehicle conveying device 1, the rainwater simulation device 2, the wiper working condition collection device 3 and the control device 4 of the utility model cooperate with each other, and the quality inspection of the vehicle automatic wiper function can be realized without too much human participation. Not only the quality inspection effect is significant, the quality inspection efficiency is high, but also the labor cost is low.

[0031] Embodiment 2:

[0032] Example 2 is based on Example 1:

[0033] like Figure 1 and Figure 2 As shown, the automated quality inspection system for the vehicle automatic wiper function includes a vehicle identification device 5 , and the vehicle identification device 5 is electrically connected to the control device 4 .

[0034] During quality inspection, the vehicle identification device 5 collects the vehicle model information of the vehicle to be inspected and transmits it to the control device 4. The control device 4 determines whether the vehicle to be inspected has an automatic wiper function based on the vehicle model information. If the vehicle has an automatic wiper function, the rain simulation device 2 and the wiper condition collection device 3 work normally. If the vehicle does not have an automatic wiper function, the rain simulation device 2 and the wiper condition collection device 3 do not work, and the vehicle conveying device 1 directly conveys the vehicle.

[0035] As an optional implementation, the control device 4 includes an industrial control host 41 , and the wiper operating condition acquisition device 3 and the vehicle identification device 5 are both electrically connected to the industrial control host 41 .

[0036] The industrial control host 41 has an archiving function, which can archive vehicle quality inspection information, which is convenient for later tracing compared to traditional manual quality inspection methods.

[0037] As an optional implementation, the vehicle identification device 5 includes a barcode scanner 51 , which is disposed on one side of the starting end of the vehicle conveying device 1 , and is electrically connected to the industrial control host 41 .

[0038] When identifying vehicle information, the vehicle VIN code can be scanned by the barcode scanner 51 to obtain the vehicle information, thereby providing a basis for whether the vehicle has an automatic wiper function.

[0039] As an optional implementation, the control device 4 includes a position detection device, and the position detection device is electrically connected to the industrial control host 41 , and the rain simulation device 2 is electrically connected to the industrial control host 41 .

[0040] During the quality inspection process, when the vehicle conveying device 1 conveys the vehicle to be inspected to the rainwater simulation device 2, the position detection device senses that the vehicle to be inspected is in place and feeds back to the industrial control host 41. The industrial control host 41 controls the rainwater simulation device 2 to turn on and performs quality inspection on the vehicle. After that, the vehicle conveying device 1 continues to convey the vehicle. When the position detection device detects that the vehicle leaves the rainwater simulation device 2 and feeds back to the industrial control host 41, the industrial control host 41 controls the rainwater simulation device 2 to turn off.

[0041] In this way, resources can be effectively saved and quality inspection costs can be saved.

[0042] As an optional embodiment, the position detection device includes a photoelectric detection component 42, and the photoelectric detection component 42 includes a transmitter and a receiver. The transmitter and the receiver are relatively arranged on two sides of the vehicle conveying device 1, and a position detection grating is formed between the transmitter and the receiver.

[0046] When simulating rainwater, clean water provided by the water pipe network flows into the nozzle 22 through the jet pipe 21 and is sprayed onto the vehicle through the nozzle 22, and the rainwater simulation effect is significant.

[0047] As an optional implementation, the rainwater simulation device 2 includes a jet valve 23 and a booster pump 24 .

[0048] The jet valve 23 is disposed on the conveying section of the jet tube 21 and is located upstream of the nozzle 22 . The jet valve 23 is electrically connected to the industrial control host 41 and is used for flow control of the jet tube 21 .

[0049] The booster pump 24 is disposed on the delivery section of the jet pipe 21 and is located upstream of the jet valve 23 . The booster pump 24 is electrically connected to the industrial control host 41 to control the jet pressure of the water flow.

[0050] As an optional implementation, the vehicle conveying device 1 includes a conveying plate chain 11 , and a positioning portion 111 is provided on the conveying plate chain 11 .

[0051] The positioning portion 111 is configured as a wheel positioning block, which limits the relative position of the wheels, thereby limiting the relative position of the vehicle.

[0052] The conveyor plate chain 11 with the positioning portion 111 is used to convey the vehicle to be inspected, which has a large load-bearing capacity, a smooth conveying process and a significant effect.

[0053] As an optional implementation, the supporting device 6 includes a second gantry 62 , which is located downstream of the first gantry 61 , and the second gantry 62 is erected above the vehicle conveying device 1 .

The camera 31 can acquire images and video information of the wiper working condition and feed it back to the industrial control host 41 .

[0055] As an optional implementation, the control device 4 also includes a quality inspection result display device and a voice broadcast device, wherein the quality inspection result display device adopts a display screen, and the voice broadcast device adopts a voice prompter.

[0056] The quality inspection result display device can intuitively display the quality inspection information of the vehicle, and the voice broadcasting device can broadcast the quality inspection information in the form of voice.

[0057] The quality inspection result display device and the voice broadcast device are both existing technologies, and their structures are not described in detail.

[0064] (IV) The photoelectric detection component 42 detects that the vehicle moves to the rain simulation device 2, the jet valve 23 and the booster pump 24 are turned on, and water flows through the jet pipe 21 to the nozzle 22 and is sprayed onto the vehicle to simulate rain;

[0065] (V) The vehicle senses rain, triggering the automatic wiper function to turn on and the wipers to operate;

[0066] (VI) The camera 31 collects the working condition information of the wiper in real time and feeds it back to the industrial control host 41;
