[0031] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0032] like Figures 1 to 4 An intelligent assembly and inspection workbench shown includes a program control module, a sensing module, a data transmission module, an indication module, a power supply module and a workbench body.

[0033] The program control module includes an industrial computer 4 and a programmable relay controller 8; the sensing module includes 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 a wireless communication device based on the TCP / IP protocol; the indication module includes a display 1, a bamboo lamp 2 and an LED indicator light 7; the power supply module includes a UPS 5 and a switching power supply 9.

[0034] The vehicle body table is provided with a display 1, a mouse and keyboard, a bamboo light 2, and a common tool tray 3. The lower left side of the table is mainly provided with electrical equipment such as a UPS 5, a switching power supply 9, an industrial computer 4, and a programmable relay controller 8. There are multiple drawers 6 on the right side below the table. Each drawer panel is provided with an LED indicator 7. An RFID antenna 12 is fixed inside the drawer and a vehicle-mounted smart tool 14 is placed thereon. An RFID electronic tag 13 is fixed on the smart tool 14. Other facilities such as a winding reel are placed at the lower part of the drawer. A proximity switch sensor 10 and an RFID card reader 11 are installed on the column near the drawer. The RFID card reader 11 is connected to the RFID antenna (12) of each drawer by a cable. The UPS 5 is connected to an external power supply and supplies power to the industrial computer 4, the display 1, the switching power supply 9, and the RFID card reader (11).

[0035] The installation distance between the proximity switch sensor 10 and the side wall of the drawer 6 is less than the sensing distance of the sensor. When the drawer 6 is pulled out to exceed the sensing range of the sensor or the drawer 6 is pushed into the sensing range of the sensor, the sensor output jumps and sends the jump 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 jump output of the proximity switch sensor 10, and immediately calls the RFID card reader 11 to detect the RFID electronic tag 13 in the vehicle. If the use of the smart tool 14 meets the process requirements, the programmable relay controller 8 outputs to control the bamboo light 2 to light green, otherwise it lights up red, and at the same time outputs to control the LED indicator light 7 to light up or off. In addition, during the waiting interval of the working step, the programmable relay controller 8 outputs to control the bamboo light 2 to light yellow.

[0036] like Figure 5 and Figure 6 As shown, the operation process of the intelligent assembly and inspection workbench of this patent is as follows:

[0037] Before use, place the smart tool 14 with the RFID electronic tag 13 into the corresponding pearl cotton groove, and then push the trolley drawer 6 completely into the vehicle body. After the power is turned on and the proximity switch 10 senses the drawer reset, the RFID card reader 11 checks the RFID electronic tag 13 inside the drawer to determine whether the smart tool 14 has returned to its place. If the smart tool 14 in the drawer is missing or taken by mistake, the bamboo light 2 will light up red, and the display 1 will prompt the operator which tool has not been returned; if the tool in the drawer has been correctly returned, the bamboo light 2 will light up green to guide the operator to take out the next tool to be used, and the LED indicator 7 on the drawer corresponding to the tool will light up. After taking out the tool correctly, close the drawer 6, the bamboo light 2 will remain green, and the display 1 will show that the task has started.

[0038] The operator uses the smart tool 14 to perform the operation. The smart tool 14 automatically collects the item point data and sends it to the industrial computer 4. The industrial computer 4 automatically records and saves and determines whether the collected item point data is qualified. If it is unqualified, the bamboo light 2 lights up red and the display 1 prompts to re-collect. After completing the current step and all the item point data are qualified, the smart tool 14 is put back into the drawer 6. This cycle is repeated until the entire production process is completed.

[0039] As described above, although the present invention has been shown and described with reference to certain preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and details may be made without departing from the spirit and scope of the present invention as defined in the appended claims.
