The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

As described in the background of the present application, after the production equipment or the material is abnormal and the production equipment is controlled to stop running, any operator can control the equipment to restart, for example, after the material in the chip mounter is abnormal and the conveyor is controlled to stop running, any operator can control the conveyor to restart, and this kind of control mode easily causes the defective product to continue flowing into the downstream, thereby affecting the normal running of the production line.

Based on this, the embodiment of the present application provides a control device 10, which is used for solving the technical problem that the normal production of a production line is affected by restarting a random control device. As shown in fig. 1, the control apparatus 10 includes a face recognition device 101, a controller 102, and a first target device 103; the face recognition device 101 is connected to a first input A1 of the controller 102, and a first output B1 of the controller 102 is connected to the first target device 103.

The face recognition apparatus 101 may acquire face information, identify the acquired face information, and send the identification result to the controller 102, where the face information may be face image information.

Specifically, the face recognition device 101 may include a camera and obtain face information through the camera; the face recognition device 101 may be configured to compare the obtained face information with target face information, where the target face information may be face information of an operator (such as a supervisor) at a certain level, or face information of other operators qualified to operate the first target device. The target face information can be input in advance by a corresponding operator and stored, and in practical application, the target face information can be stored in a cloud or a local memory. In the case that the target face information is stored in the cloud, the face recognition device 101 may have a function of communicating with the cloud to obtain the target face information stored in the cloud, and an operator corresponding to the target face information may input the face information through another mobile terminal (such as a mobile phone, a computer, etc.) and store the face information in the cloud. In the case where the target face information is stored in the local memory, the face recognition apparatus 101 may include the local memory, and the operator corresponding to the target face information may input the face information through the face recognition apparatus 101, and the face recognition apparatus 101 stores the target face information in the local memory. The face recognition device 101 compares the acquired face information with the target face information, and if the acquired face information is matched with the target face information, the face recognition device can output successful face recognition information and send the information to the controller 102; if the acquired face information does not match the target face information, face recognition failure information can be output and sent to the controller 102. In order to improve the accuracy of face recognition, multiple times of recognition can be performed. The face recognition apparatus 101 may further include a display screen for displaying the acquired face information, such as a face image, and displaying a face recognition result.

The face recognition device 101 is connected to the first INPUT terminal of the controller 102, and may be directly connected to an I/O (INPUT/OUTPUT), or connected to a USB (Universal Serial Bus), as shown in fig. 2.

The controller 102 may control the first target device 103 according to the face recognition result transmitted by the face recognition device 101. The Controller 102 may be an Industrial Personal Computer (IPC), and may specifically be a Programmable Logic Controller (PLC). The controller 102 has a plurality of inputs for receiving information from different devices and a plurality of outputs for sending control commands to different devices. The controller 102 may be embedded with logic operation software for operating the received information to obtain a corresponding control instruction. In this embodiment of the application, the controller 102 may perform an operation according to the information about whether the face recognition is successful or not sent by the face recognition device 101 to obtain a corresponding control instruction, for example, perform an operation according to the information about the success of the face recognition to obtain a control instruction for controlling the start of the first target device; or, performing operation according to the face recognition failure information to obtain a control instruction for controlling the first target device not to be started.

The first target device 103 may be a device that experiences a machine failure or material anomaly, such as a placement machine, or may be a device that is not experiencing a failure downstream from the placement machine, such as a conveyor or elevator. When the first target device 103 is a chip mounter with a machine fault or material abnormality, face recognition can be performed, the chip mounter is controlled to be restarted through the controller 102, and the situation that the normal operation of a production line is influenced because the chip mounter is started at will and continues to be in a fault state is avoided. When the first target device 103 is a conveyor or a lifter which is located at the downstream of the chip mounter and has no fault, the face recognition can be performed, the controller 102 controls the conveyor or the lifter to be restarted, and the situation that the conveyor or the lifter is started randomly to continuously transport the defective products to the downstream to influence the normal operation of a production line is avoided.

In practical applications, the controller 103 may be located at a location remote from the work site to facilitate remote control.

It can be understood that, in the control device 10 provided in this embodiment of the present application, by connecting the face recognition device 101 to the input end a1 of the controller 102 and connecting the output end B1 of the controller 102 to the first target device, the face recognition device 101 may transmit information about whether the face recognition is successful or not to the controller, and the controller 102 may control the first target device 103 to restart when the information transmitted by the face recognition device 101 is successful in face recognition; therefore, the operator who stores the corresponding face information in the face recognition device 101 can control the first target device to restart, and the influence on normal production of a production line caused by the fact that any operator randomly controls the first target device 103 to restart is avoided.

In practical applications, in order to facilitate the controller 102 to control the first target device 103, in an embodiment, the control device 10 provided in this embodiment of the present application further includes a first relay J1 and a first switch K1, as shown in fig. 3, the first output terminal B1 of the controller 102 is connected to one end of the first relay J1, and the other end of the first relay J1 is connected to the output common terminal COM of the controller 102; the first switch K1 and the first target device 103 constitute a control circuit, and the first switch K1 corresponds to the first relay J1.

The first output terminal B1 and the output common terminal COM may be connected to the first relay J1, specifically, to a coil of the first relay J1. One end of the first relay J1 is connected to the first OUTPUT terminal B1 of the controller 102, which may be an INPUT/OUTPUT (INPUT/OUTPUT) connection, as shown in fig. 3.

The first switch K1 forms a control loop with the first target device 103, and it is understood that the closing of the first switch K1 controls the activation of the first target device 103.

The first switch K1 corresponds to the first relay J1, and specifically, whether or not the coil of the first relay J1 is energized can control the state of the first switch K1. For example, energizing the coil of the first relay J1 may control the first switch K1 to close.

It can be understood that, with the above-described scheme, the first output terminal B1 of the controller 102 is connected to one end of the first relay J1, and the other end of the first relay J1 is connected to the output common terminal COM of the controller 102; first switch K1 constitutes control circuit with first target device 103, and first switch K1 corresponds with first relay J1 for when the information that face recognition device 101 transmitted was face identification success, controller 102 can control the coil of first relay J1 and get electric, and then first switch K1 is closed, thereby control first target device 103 restart, can improve accuracy and the convenience of controlling first target device 103 restart.

In order to avoid the restart operation of the operator who is not qualified to operate the first target device 103 and to remind other operators (such as the operator who is qualified to operate the first target device 103) to check in time, in an embodiment, the control device 10 provided in this embodiment of the present application further includes an alarm device 104 and a second switch K2, as shown in fig. 4, the alarm device 104 and the second switch K2 form a control loop, and the second switch K2 corresponds to the first relay J1.

Wherein, the alarm device 104 can be used to send out alarm information, the alarm device 104 can include a warning light and/or a buzzer, and when the alarm device 104 includes a warning light and a buzzer, the warning light and the buzzer can be connected in series or in parallel in a circuit, as shown in fig. 5-1 and fig. 5-2. The alarm device 104 may be disposed on the controller 102, or may be disposed on the first target device 103, so as to facilitate other operators to determine specific restart devices of the operators who do not have the manipulation qualification.

The alarm device 104 and the second switch K2 form a control loop, and it is specifically understood that the closing of the second switch K2 can control the operation of the alarm device 104, such as the flashing of a warning light and/or the sounding of a buzzer, and the opening of the second switch K2 can control the stop of the operation of the alarm device 104.

The second switch K2 corresponds to the first relay J1, and specifically, whether or not the coil of the first relay J1 is energized can control the state of the second switch K2. For example, a loss of power to the coil of the first relay J1 may control the second switch K2 to close.

It can be understood that, through the above scheme, the control device 10 further includes an alarm device 104 and a second switch K2, the alarm device 104 and the second switch K2 form a control loop, the second switch K2 corresponds to the first relay J1, when the information transmitted by the face recognition device 101 is face recognition failure, the coil of the first relay J1 loses power, and further the second switch K2 is controlled to be closed, so as to control the alarm device 104 to work and send out warning information, so that an operator who does not have the qualification of controlling the first target device 103 can be warned when the first target device 103 is operated, and other operation technicians (such as an operator who has the qualification of restarting the first target device 103) can be reminded to check in time. Then, after the operator qualified to operate the first target device 103 performs face recognition, the face recognition device 101 transmits information that the face recognition is successful, the coil of the first relay J1 is powered on, the second switch K2 is controlled to be turned off, the alarm device 104 stops working, the first switch K1 is controlled to be turned on, and the first target device 103 is controlled to be restarted.

In order to further ensure normal production of the production line, in an embodiment, the control device 10 provided in the embodiment of the present application further includes a failure release information input device 105, as shown in fig. 6, where the failure release information input device 105 is connected to the second input terminal a2 of the controller 102.

The failure release information input device 105 may be used for an operator to input a failure release instruction, among others. The failure release information input device 105 may be a button provided on the controller 102, and an operator may input a failure release instruction by activating the button. The failure release instruction may be a failure release instruction for the first target device 103, for example, when the first target device 103 fails (including a machine failure and/or a material abnormality), after the failure of the first target device 103 is released, an operator inputs the failure release instruction for the first target device 103 through the failure release information input device 105. The failure removal instruction may also be a failure removal instruction for another device, for example, the other device having the failure is a chip mounter, the first target device 103 is a conveyor or a lifter which does not have the failure downstream of the chip mounter, after the failure of the chip mounter is removed, an operator inputs the failure removal instruction of the chip mounter through the failure removal information input device 105, and then the conveyor or the lifter downstream of the chip mounter can be controlled to restart in combination with the face recognition.

In practical applications, the failure release information input device 105 may be used not only to input a failure release instruction, but also to trigger the face recognition device 101 to start face recognition. For example, after the operator inputs the failure release instruction through the trigger key, the face recognition device 101 may turn on the camera to obtain the face information. Of course, when controlling the first target device 103 to restart, the failure removal instruction may be input through the failure removal information input device 105 first, and then the face recognition may be performed; the face recognition may be performed by the face recognition apparatus 101, and then the failure release instruction may be input by the failure release information input apparatus 105.

The failure relief information INPUT device 105 is connected to the second INPUT terminal a2 of the controller 102, and may be directly connected to an I/O (INPUT/OUTPUT).

It can be understood that, with the above-mentioned solution, the control device 10 further includes the failure removal information input device 105, and the failure removal information input device 105 is connected to the second input end a2 of the controller 102, so that the controller 102 can control the first target device 103 to restart under the condition that the failure removal and the face recognition are successful, thereby avoiding that the controller 102 controls the first target device 103 to restart under the condition that the failure is not removed, and further ensuring the normal production of the production line.

Considering that when a failure occurs and the first target device 103 is not controlled to stop operating in time, production is affected, for example, when a chip mounter has a machine failure and/or material abnormality, if the downstream conveyor is not controlled to stop operating in time, a defective product flows downstream; therefore, in an implementation manner, the control device 10 provided in the embodiment of the present application further includes an information collecting device 106, as shown in fig. 7, where the information collecting device 106 is connected to the third input terminal a3 of the controller 102.

The information collecting device 106 may be configured to collect equipment operation state information, including machine operation information and/or material information, judge whether a machine is faulty or not and judge whether a material is abnormal or not, and transmit a judgment result to the controller 102, where the judgment result may be transmitted by using an XML file. The object of the information collection device 106 for collecting the operation state information may be the first target device 103, or may be another device.

The information collecting apparatus 106 is connected to the third INPUT terminal a3 of the controller 102, and may be directly connected to an I/O (INPUT/OUTPUT) or connected to an ethernet.

It can be understood that, through the above solution, the control device 10 further includes the information acquisition device 106, the information acquisition device 106 is connected to the third input end a3 of the controller 102, and the controller 102 can timely control the first target device 103 to stop operating when the information transmitted by the information acquisition device 106 is that there is a fault.

In order to facilitate the controller 102 to control the operation state of the first target device 103, in one embodiment, the control apparatus 10 provided in the embodiment of the present application further includes a second relay J2 and a third switch K3; as shown in fig. 8, the second output terminal B2 of the controller 102 is connected to one end of the second relay J2, and the other end of the second relay J2 is connected to an output common terminal COM of the controller 102; the third switch K3 constitutes a control circuit with the first target device 103, and the third switch K3 corresponds to the second relay J2.

The second output terminal B2 and the output common terminal COM may be connected to the second relay J2, specifically, to a coil of the second relay J2. One end of the second relay J2 is connected to the second OUTPUT terminal B2 of the controller 102, which may be an INPUT/OUTPUT (INPUT/OUTPUT) connection, as shown in fig. 8.

The third switch K3 forms a control loop with the first target device 103, and it is understood that the opening of the third switch K3 can control the first target device 103 to stop operating.

The third switch K3 corresponds to the second relay J2, and specifically, whether or not the coil of the second relay J2 is energized can control the state of the third switch K3. For example, energizing the coil of the second relay J2 may control the third switch K3 to open.

The third switch K3 and the first switch K1 may be the same switch, as shown in fig. 8, the third switch K3 and the first switch K1 may also be different switches, as long as the third switch K3 is opened, the first target device 103 stops operating, the first switch K1 is closed, and the first target device 103 restarts.

It can be understood that, with the above-described scheme, the second output terminal B2 of the controller 102 is connected to one end of the second relay J2, and the other end of the second relay J2 is connected to the output common terminal COM of the controller 102; the third switch K3 and the first target device 103 form a control loop, and the third switch K3 corresponds to the second relay J2, so that when the information transmitted by the information acquisition device 106 is in a fault, the coil of the second relay J2 is powered on, and the third switch K3 is controlled to be switched off, so that the first target device 103 is controlled to stop running, and the accuracy and convenience for controlling the first target device 103 to stop running can be improved. After the fault is resolved, after the human face recognition can be performed by an operator qualified to control the first target device 103, the information transmitted by the human face recognition device 101 is that the human face recognition is successful, the coil of the first relay J1 is powered on, and the first switch K1 is controlled to be closed, so that the first target device 103 is controlled to be restarted.

In an implementation manner, the control apparatus 10 provided in this embodiment of the present application further includes a second target device 107, as shown in fig. 9, and the information collecting device 106 is connected to the second target device 107.

It can be understood that, by the above scheme, the control apparatus 10 further includes the second target device 107, and the information collection device 106 is connected to the second target device 107, so that the information collection device 106 can collect the operation state information of the second target device 107, and when the second target device 107 has a fault, the controller 102 can control the first target device 103 to stop operating. For example, the second target device 107 is a chip mounter, the first target device 103 is a conveyor, and when the chip mounter fails, the controller 102 may control the conveyor to stop operating, so as to prevent the defective products from continuously flowing downstream.

In practical applications, when the information acquisition device 106 acquires material information of the second target device 107, in order to accurately determine whether the material is abnormal, in an implementation manner, the control apparatus 10 provided in this embodiment of the present application further includes a warehouse material management device 108, as shown in fig. 10, where the information acquisition device 106 is connected to the warehouse material management device 108.

The warehouse material management device 108 may have a mapping relationship between the material number and the work station pre-stored therein, and may send the mapping relationship to the information acquisition device 106. When the information acquisition device 106 acquires the material information of the second target device 107, the serial number of the material assembled at the second target device 107 and the corresponding work station can be acquired, and the material information can be acquired through the scanning gun. The information acquisition device 106 may compare the mapping relationship, and determine whether the material number assembled in the second target device 107 matches the work station, if so, the material is normal, and if not, the material is abnormal.

It can be understood that, through the above scheme, the control apparatus 10 further includes a warehouse material management device 108, and the information collection device 106 is connected to the second target device 107 and the warehouse material management device 108, so that the information collection device 106 can accurately determine whether the second target device 107 has material abnormality, and if the material abnormality occurs, the controller 102 can control the first target device 103 to stop operating.
