Description

Technical Field

[0001] The present application relates to the technical field of vehicle refrigerator transport detection, and in particular to a vehicle refrigerator transport device with a plug-in and unplug identification function. Background Art

[0002] The refrigeration test of the car refrigerator assembly line is one of the core links in the production process of car refrigerators. Its main purpose is to ensure that the refrigeration performance of the produced car refrigerators meets the design specifications and quality standards. The assembly line usually includes the following steps: the factory that produces car refrigerators usually sets up a special car refrigerator assembly line to transfer the car refrigerators from the production line to the testing position; at the testing position, the operator needs to provide power to the car refrigerator so that the testing equipment can operate normally; insert the temperature detection device into the car refrigerator for temperature detection. During the temperature detection, the temperature inside the car refrigerator will be monitored and recorded, and then compared and analyzed according to the preset standards; after the test is completed, the test results will be sent to the staff for review and processing.

[0003] After the inspection is completed, the staff needs to unplug the power cords of all the car refrigerators on the assembly line from the power supply, unplug all the temperature detection devices from the car refrigerators, and then start the conveyor belt to transport the batch of car refrigerators; during this period, since the staff need to operate a large number of car refrigerators, if there is any omission or negligence in unplugging the temperature detection device or the power cord, and then starting the transmission, the power cord or the temperature detection device will be damaged under the action of the conveying force. Therefore, a detection device is urgently needed to detect whether the temperature detection device or the power cord is unplugged, so as to ensure that the conveyor belt can only be started again when all the wiring harnesses are unplugged. Utility Model Content

[0004] The present invention provides a vehicle-mounted refrigerator transport device with plug-in and unplug identification function, and the specific implementation method is as follows:

[0005] A main conveyor belt and several branch conveyor belts evenly arranged at equal distances along the conveying direction of the main conveyor belt. The main conveyor belt is a roller conveying structure, and a lifting and transferring assembly is installed at the internal gap thereof. The lifting and transferring assembly is used to vertically transfer the vehicle refrigerator from the main conveyor belt to the branch conveyor belt. Several vehicle refrigerator detection positions are evenly spaced along the conveying direction of the branch conveyor belt;

[0006] A temperature sensor is installed above the detection position and a power supply socket is installed below the detection position. The power supply socket is connected to the power supply harness of the vehicle refrigerator. The temperature sensor is used to detect the temperature when the vehicle refrigerator is running and is inserted into the refrigeration cavity.

[0007] The controller has an input end electrically connected to the temperature sensor, and an output end electrically connected to the main conveyor belt and the branch conveyor belt. After the detection is completed and the controller detects that there is no low-temperature input to each temperature sensor, the branch conveyor belt is turned on to transport the vehicle refrigerator. If there is low-temperature input, it proves that the temperature sensor has not been pulled out of the refrigeration chamber, and the branch conveyor belt will not be operated.

[0008] Preferably, it also includes a photoelectric sensor electrically connected to the controller, the photoelectric sensor is integrated on the panel of the power socket, and is used to detect whether the plug of the power supply harness is unplugged from the power socket.

[0009] Based on the above technical solution, when the temperature sensor is higher than the specified set low temperature, the indicator light is green, which means that the temperature sensor is removed. Otherwise, it means that the temperature sensor has not been removed. Even after the car refrigerator stops supplying power, the internal temperature will still remain low for a certain period of time, which is lower than the set low temperature. Therefore, the temperature sensor can be used to determine whether it is removed before starting the conveyor belt for the second time.

[0011] Based on the above technical solution, a guide rail or a hoist can be added to the crossbeam of the frame, so that each temperature sensor harness has the function of position adjustment to cope with the adjustment of the corresponding relationship between the distance between the vehicle refrigerators and the position of the vehicle refrigerators after the modification.

[0012] Preferably, it also includes a human-machine interface electrically connected to the controller, on which an emergency stop button, indicator lights and branch buttons are integrated, and the number of branch buttons corresponds to the number of indicator lights. The branch buttons are used to control the start and stop of each branch conveyor belt, and the indicator lights are used to prompt whether the power supply harness and temperature sensor on the branch conveyor belt are removed.

[0013] Based on the above technical solution, the emergency stop button is used to control the one-touch shutdown of all conveyor belts to prevent major safety accidents; at the same time, the branch button controls the start and stop of the corresponding branch conveyor belt, and the indicator light shows green, indicating that all wiring harnesses on the branch conveyor belt have been removed.

[0014] Preferably, the trunk conveyor belt includes a first bracket, and the roller conveying structure is composed of a plurality of rollers, each of which is installed at an equal distance on the top of the first bracket.

[0015] Preferably, the branch conveyor belt includes a second bracket and a conveyor belt arranged on the second bracket, and the second bracket is equipped with a motor, and an output end of the motor is connected to the conveyor belt.

[0017] Preferably, it also includes the same number of pallets as the vehicle refrigerator, and the pallets are placed at the bottom of the vehicle refrigerator to increase the contact area between the main conveyor belt and the branch conveyor belt, thereby improving the transportation stability of the vehicle refrigerator.

[0018] Based on the above technical solution, the shape of the vehicle refrigerator is not a square structure, and its lower cross-sectional area is smaller than the upper cross-sectional area. At the same time, it will pass through a roller conveyor structure with gaps. Therefore, adding a pallet can effectively improve the stability of the vehicle refrigerator transportation; the lifting and transfer component is an existing conventional belt conveyor structure, and a conventional lifting mechanism is provided at the bottom. The lifting and transfer component is also electrically connected to the controller.
