Detailed Description

The invention is described in further detail below with reference to the accompanying drawings:

as shown in fig. 1 to 4, the intelligent assembly detection working trolley comprises a program control module, a sensing module, a data transmission module, an indication module, a power supply module and a working trolley body.

The program control module comprises an industrial personal computer 4 and a programmable relay controller 8; the induction module comprises an RFID card reader 11, an RFID antenna 12, an RFID electronic tag 13 and a proximity switch sensor 10; the data transmission module is wireless communication equipment based on a TCP/IP protocol; the indicating module comprises a display 1, a bamboo joint lamp 2 and an LED indicating lamp 7; the power supply module includes a UPS5 and a switching power supply 9.

A display 1, a mouse keyboard, a bamboo joint lamp 2 and a common tool tray 3 are arranged on the table top of the vehicle body, and electrical equipment such as a UPS5, a switching power supply 9, an industrial personal computer 4 and a programmable relay controller 8 are mainly arranged on the left side of the lower portion of the table top. The right side below the table top is provided with a plurality of layers of drawers 6, an LED indicator light 7 is arranged on a panel of each layer of drawer, an RFID antenna 12 is fixed inside the drawer and a vehicle-mounted intelligent tool 14 is placed inside the drawer, an RFID electronic tag 13 is fixed on the intelligent tool 14, other facilities such as a wire reel and the like are placed on the lower portion of the drawer, a proximity switch sensor 10 and an RFID card reader 11 are arranged on a stand column close to the drawer, and the RFID card reader 11 is connected with the RFID antenna (12) of each drawer through a cable. The UPS5 is connected with an external power supply and supplies power to the industrial personal computer 4, the display 1, the switching power supply 9 and the RFID card reader (11).

The installation distance between the proximity switch sensor 10 and the side wall of the drawer 6 is smaller than the sensing distance of the sensor. When the drawer 6 is pulled out beyond the sensing range of the sensor or the drawer 6 is pushed into the sensing range of the sensor, a jump occurs in the sensor output and the jump is sent to the programmable relay controller 8. When the drawer 6 is pushed into the sensing range of the sensor, the programmable relay controller 8 detects the jumping output of the proximity switch sensor 10, the RFID card reader 11 is immediately called to detect the RFID electronic tag 13 in the vehicle, if the use condition of the intelligent tool 14 meets the process requirements, the programmable relay controller 8 outputs and controls the bamboo joint lamp 2 to be bright green, otherwise, the bamboo joint lamp is bright red, and simultaneously outputs and controls the LED indicating lamp 7 to be bright and dark.

As shown in fig. 5 and 6, the operation process of the intelligent assembly detection trolley of the present patent is as follows:

before use, the intelligent tool 14 attached with the RFID electronic tag 13 is placed into the corresponding pearl wool groove, and then the trolley drawer 6 is completely pushed into the trolley body. After the power is switched on and the proximity switch 10 senses the reset of the drawer, the RFID card reader 11 checks the RFID electronic tag 13 in the drawer and judges whether the intelligent tool 14 is reset. If the intelligent tool 14 in the drawer is missing or taken wrongly, the bamboo joint lamp 2 is bright red, and the display 1 prompts an operator which tool is not returned; if the tool in the drawer is correctly reset, the bamboo joint lamp 2 is bright green, an operator is guided to take out the next tool to be used, and the LED indicator lamp 7 on the corresponding drawer of the tool is lightened. After the tool is correctly taken out, the drawer 6 is closed, the bamboo joint lamp 2 keeps a green lamp, and the display 1 displays that the task is started.

The operator uses intelligent tool 14 to carry out the operation, and intelligent tool 14 will automatic acquisition item data and send for industrial computer 4, and whether the item data of industrial computer 4 automatic recording save and judgement collection is qualified, if unqualified then the bamboo joint lamp 2 is bright red, and the suggestion of display 1 is gathered again. After the current process step is completed and all the item data are qualified, the intelligent tool 14 is put back into the drawer 6. The process is circulated until the whole production process is completed.

As noted above, while the present invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limited thereto. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
