[0039] Wherein, ① the identification device 130 is respectively arranged on each detection point on the general assembly tool, and one identification device 130 is arranged on each detection point. ② The electromagnetic air control valve 120 adopts a two-position two-way electromagnetic valve. The electromagnetic air control valve 120 is arranged on the pneumatic control console of the general assembly tool, the air inlet end of the electromagnetic air control valve 120 is connected with the air inlet source of the pneumatic control console, the air outlet end of the electromagnetic air control valve 120 is connected with the control switch of the pneumatic control console, and the electromagnetic air control valve 120 is used for controlling the opening or closing of the clamping action of the general assembly tool. ④ The at least one identification device 130 comprises at least one optical fiber amplifier and / or at least one laser diffuse reflection sensing switch.

[0040] It should be noted that the working principles of the optical fiber amplifier and the laser diffuse reflection sensing switch are the same, and both are used for collecting the shape contour of the target point and the position degree of the part. The specific working principle is prior art, which will not be described in detail here.

[0041] The PLC controller 110 is used for:

[0042] When the assembly identification signal of the target part is received, the shape contour and the current position degree of the target area of the part to be measured are obtained by using the identification device 130 on the detection point corresponding to the target part.

[0043] Wherein, ① the target part is the part that needs to be assembled at present. ② The assembly identification signal is the signal that needs to be identified before assembly of the target part, which is generated according to the input of the user. ③ One part corresponds to at least one detection point, that is, one part corresponds to at least one detection point, and each detection point corresponds to an identification device 130. ④ The identification device 130 obtains the position of the point where the shape contour of the part is arranged. If a part corresponds to multiple detection points, the shape contour and the current position degree collected by multiple optical fiber amplifiers are used.

[0044] It should be noted that the position degree is a parameter that is designed and adjusted on the general assembly tool according to the size of the part.

[0045] It is judged whether the shape contour of the part to be measured is the same as the shape contour of the target part, and a first judgment result is obtained, and it is judged whether the current position degree of the part to be measured is within the preset position degree range, and a second judgment result is obtained.

[0046] Wherein, the shape contour of the target part and the preset position degree range are all pre-stored in the PLC controller 110.

[0047] When the first determination result and the second determination result are both yes, the electromagnetic air control valve 120 is controlled to be turned on, so as to control the general assembly tool to perform assembly on the target part through the control switch.

[0048] Specifically, when the shape contour of the to-be-tested part is the same as that of the target part and the current position degree of the to-be-tested part is within the preset position degree range, the PLC controller 110 controls the electromagnetic air control valve 120 to be turned on, so as to control the general assembly tool to perform assembly on the target part through the control switch.

[0049] Preferably, the PLC controller 110 is further configured to:

[0050] When at least one of the first determination result and the second determination result is no, the electromagnetic air control valve 120 is controlled to be turned off, so as to disconnect the control switch from controlling the general assembly tool.

[0051] Specifically, when the shape contour of the to-be-tested part is not the same as that of the target part, or the current position degree of the to-be-tested part is not within the preset position degree range, the PLC controller 110 controls the electromagnetic air control valve 120 to be turned off, so as to disconnect the control switch from controlling the general assembly tool.

[0052] Preferably, the system further comprises an alarm device 140.

[0053] The PLC controller 110 is further configured to:

[0054] When the first determination result and the second determination result are both yes, the alarm device 140 is controlled to output prompt information.

[0055] Wherein, ① the alarm device 140 is a three-color warning light; and ② when the alarm device 140 is a three-color warning light, the first alarm information is that the three-color warning light presents green.

[0056] When at least one of the first determination result and the second determination result is no, the alarm device 140 is controlled to output second alarm information.

[0057] Wherein, when the alarm device 140 is a three-color warning light, the second alarm information is that the three-color warning light presents red.

[0058] Preferably, the system further comprises a touch display screen 150.

[0059] Wherein, the touch display screen 150 is a common display screen on the market, which is connected with the PLC controller 110 and is configured to send the assembly identification signal corresponding to the part to be identified to the PLC controller 110 according to the assembly identification signal input by a user.

[0060] The touch display screen 150 is configured to receive the assembly identification signal of the target component input by the user and send it to the PLC controller 110.

[0061] It should be noted that the touch display screen 150 is written with the product model classification program required for production. When the user clicks on the production plan set on the touch display screen 150 during production, the touch display screen 150 generates the assembly identification signal of the related components of the product corresponding to the production plan and sends it to the PLC controller 110.

[0062] Preferably, the system further comprises a power module 160.

[0063] The power module 160 is configured to supply power to each device in the component identification system 100.

[0064] Preferably, the power module 160 adopts a 24V power supply by default, and can be adjusted according to actual needs, which is not limited herein.

[0065] In order to better illustrate the technical solutions of the present embodiment, the following examples are used for illustration:

[0066] The total assembly tool is an intelligent automatic identification total assembly welding tool for the cab welding line of a tractor.

[0067] The target component is a side wall framework used for the cab. Since the side wall framework has multiple different models, this example is used for illustration.

[0068] Specifically, a program is written on the PLC controller 110, a classification model calling menu for different side wall skeletons used for different cab models is written on the touch display screen 150, and the PLC controller 110 is connected with the touch display screen 150 through a data wire to realize data connection, so that the PLC controller 110 receives the assembly identification signal generated by the touch display screen 150. When the user produces a cab, the touch display screen 150 directly calls out the corresponding model of the side wall skeleton corresponding to the model of the cab produced by the user after the user clicks the model of the cab produced on the touch display screen 150. After the user clicks the start button, the intelligent automatic identification system in the PLC controller 110 immediately enters the start state. When the side wall skeleton installed by the user must meet two conditions at the same time: condition 1. The model of the installed side wall skeleton must be correct; 2. The side wall skeleton must be installed to the specified position, the total assembly tool can enter the normal working state only when the two conditions are met at the same time. At this time, the user presses the clamping switch button of the total assembly tool, the green light of the three-color warning light of the total assembly tool is on, the total assembly tool normally runs into the normal clamping work, and after the clamping is completed, the user directly welds. When the model of the side wall installed by the user is incorrect or the installed side wall skeleton is not installed to the specified position, the alarm function of the total assembly tool is triggered at this time, the red light of the three-color warning light is on, and the buzzer alarms. At the same time, the electromagnetic pneumatic valve 120 of the total assembly tool automatically cuts off the air path on the total assembly tool. At this time, the user presses any clamping button on the total assembly tool, and the total assembly tool will not perform any action. The user must install the correct side wall skeleton and install the side wall skeleton to the specified position at the same time. Only when the two conditions are met at the same time, the total assembly tool can normally start and enter the working state.

[0069] The technical scheme of the embodiment can automatically identify the assembly of parts, solve the occurrence of quality problems such as misloading, missing loading of parts on the production line, and deviation of the size of parts due to clamping not in place, and improve the production quality.

[0070] Figure 2 An embodiment of a flowchart of a part assembly identification method provided by the application is shown. As shown in Figure 2 The method comprises the following steps:

[0071] Step 210: When the PLC controller receives the assembly identification signal of the target part, the identification device on the detection point corresponding to the target part is used to obtain the contour and current position degree of the to-be-measured part in the target area;

[0072] Step 220: The PLC controller judges whether the contour of the to-be-measured part is the same as the contour of the target part to obtain a first judgment result, and judges whether the current position degree of the to-be-measured part is within the preset position degree range to obtain a second judgment result;

[0073] Step 230: when the first judgment result and the second judgment result are both yes, the PLC controller controls the electromagnetic pneumatic control valve to be connected, so as to control the general assembly tool to assemble the target part through the control switch.

[0074] More preferably, further comprising:

[0075] When at least one of the first judgment result and the second judgment result is no, the electromagnetic pneumatic control valve is controlled to be cut off, so as to disconnect the control switch from controlling the general assembly tool.
