[0033] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0034] Example 1

[0035] The existing assembly adopts the master-apprentice model for training, combined with the work instructions, and long-term learning is required to be competent for the job content and ensure the quality of product assembly; but due to the long training cycle, high personnel turnover, low assembly efficiency and high labor costs, this application proposes an instrument box assembly instruction system to overcome the above problems and provide an assembly instruction system to help operators quickly get started with zero basic knowledge, thereby ensuring product assembly quality while improving assembly efficiency.

[0036] The instrument box assembly indication system includes a workbench 3, a material rack and an indication device, wherein the indication device includes a controller, a communication module, a relay, a sensor group arranged on the workbench 3 for detecting whether assembly has started, a sensor array arranged on the material rack for judging whether materials have been taken and the quantity of materials, a signal light 5 arranged on the material rack for prompting the process and the taking status, and a display device 1 for video and voice guidance of operations. The controller, the relay and the signal light 5 are connected in sequence, the controller, the communication module and the display device 1 are connected in sequence, and the sensor array and the sensor group are respectively connected to the controller.

[0037] Working principle: When the tooling vehicle containing materials enters the predetermined position, the sensor (photoelectric sensor) detects the quantity of materials, and the material information data is transmitted to the controller through the bus to determine whether the quantity meets the set value. If it meets the set value, the metal proximity switch and infrared sensor on the workbench detect whether to start assembly. If assembly has not started, a prompt will be given. If assembly starts, the signal light on the material rack corresponding to the material required for the first process will be triggered to prompt. The infrared sensor on the material rack determines whether the material is taken correctly. If it is correct, the green signal light will be triggered while the signal light on the material rack corresponding to the material required for the next process will be triggered, and the display device will be triggered for video guidance and voice guidance. If the material is taken incorrectly, the red signal light will be triggered for prompting. The video guidance and voice guidance include installation methods, installation sequence and key quality control points, etc.; until the installation is completed, the clock module starts timing when the assembly starts, and the clock module stops timing when the assembly is completed; when the instrument box is assembled and leaves the workbench, the sensor under the table inputs the signal into the controller, the entire assembly sequence is reset, the system records the assembly time, and completes the instrument box counting; if the material quantity is less than the set value, the system automatically sends a delivery request message to the material delivery personnel through the wireless communication module.

[0038] The present invention guides operators to assemble through an indication system, wherein material guidance for the next process and video and voice guidance for the current process are provided according to the material availability, thereby ensuring assembly quality, reducing assembly difficulty, and facilitating operators with no basic knowledge to quickly get started and complete the work quickly and independently, thus saving labor costs and improving assembly efficiency.

[0039] Example 2

[0040] Based on Example 1, since there are a large number of infrared sensors, an acquisition card expansion interface is used, and two ports are used for expansion to collect 128 sensor data, which greatly simplifies the device and improves the collection efficiency.

[0041] The communication module of the present application includes a CAN communication circuit and a wireless communication circuit, the display device includes a PC, and the controller is connected to the CAN communication circuit through a bus interface and then connected to the PC. Bus communication is used for data transmission, which is stable and reliable; wireless communication circuits can also be used for transmission, which can be selected according to needs. Figure 3-4 As shown, the wireless communication circuit is as follows Figure 2 and 5 As shown, the models and values ​​of the selected devices are shown in the figure. Those skilled in the art can clearly and completely implement the technical solution of the present application based on the records of the present application.

[0042] The sensor group includes a metal proximity switch and an infrared sensor for detecting whether assembly has started. The metal proximity switch and the infrared sensor are connected to the controller respectively. The metal proximity switch and the infrared sensor are installed on the workbench 3. The sensor array includes a laser beam sensor and a photoelectric sensor for detecting a large number of small materials, and an infrared sensor group 4 for judging whether the materials are taken. The infrared sensor group 4 is connected to the controller through an acquisition card, and the laser beam sensor and the photoelectric sensor are connected to the controller respectively. The material rack includes a small material rack 6, a large material rack 7 and a standard material rack 2. The standard material rack 2 is provided with a laser beam sensor and a photoelectric sensor. The small material rack 6 and the large material rack 7 are respectively provided with an infrared sensor group 4. An infrared sensor is installed at a material placement slot.

[0043] This application detects the quantity of materials through a photoelectric sensor module, and the photoelectric sensor model is E18-D80NK; the infrared sensor detects whether the material has been taken, and the infrared sensor model is E18-D80NK. The laser beam sensor is set in the standard rack, and the quantity taken is determined by detecting the use of the operator. Its model is TB12D-T20N. The metal proximity switch and infrared sensor are installed on the workbench, and the metal proximity switch model is LJ12A34Z / BX. The detection principle is: the first step in assembling the instrument box is to put the instrument box bottom plate into the workbench. The workbench is embedded with a metal proximity switch and an infrared sensor. When the metal proximity switch detects the instrument box bottom plate, the system determines that the entire assembly has begun; the metal switch detection distance is only a few millimeters. During the assembly process, the instrument box may need to be lifted a certain distance, which may cause the metal proximity switch to lose the signal, and the infrared sensor has a longer detection distance, which can reach tens of centimeters. Therefore, after detecting that the metal proximity switch has lost its signal, the system will continue to determine whether the infrared sensor has a signal (referring to detecting that there is an instrument box bottom plate on the workbench). If the infrared sensor also loses its signal, the system determines that the entire assembly is over. The specific circuit is as follows Figure 2 and 8As shown, the infrared sensor installed on the material rack not only plays the role of judging whether the object is taken, but also plays the role of triggering the next process guidance. For example, after material A of the second step is correctly taken, the infrared sensor transmits a signal to the controller, and the controller triggers the relay to flash the green signal light to prompt that it is correct. At the same time, the display device is controlled to provide video guidance and voice guidance, and the signal light on the material rack of the next process is triggered to flash. The operator can operate it in a fool-proof manner, which is easy to get started and has high assembly efficiency.

[0044] The controller triggers the corresponding signal light 5 according to the data transmitted by the sensor. The controller controls the corresponding signal light 5 through the relay. The circuit connection of the controller, the relay and the signal light 5 is as follows: Figure 2 and 6 As shown, the models and values ​​of the selected devices are shown in the figure. Those skilled in the art can clearly and completely implement the technical solution of the present application based on the records of the present application.

[0045] The clock module starts timing when the assembly starts, and stops timing when the assembly is completed; the clock module model is DS1302, and the circuit connection is as follows Figure 2 and 7 shown.

[0046] The present invention determines whether to start assembly through metal proximity switches and infrared sensors. After the assembly starts, the signal light displays the materials required for the first process. The use status and the use quantity are determined according to the infrared sensor, photoelectric sensor and laser beam sensor. After the operator uses the materials, video and voice guidance and signal lights are used to remind the operator of the next process according to the use status. Each process corresponds to an operation instruction, which is conducive to the operator to quickly break away from the instruction book or the master to carry out the operation, thereby ensuring the operation quality and improving the assembly efficiency.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
