Method of operation of terminal connection induction system

The working method of the terminal wiring induction system is applied to the terminal wiring induction system in the first embodiment or the third embodiment of the terminal wiring induction system, and the working method is mainly used for controlling the terminal wiring induction system to guide workers to assemble wiring terminals of connecting wires and a plurality of wires, so that the problem that the workers need to set wire number tubes or labels at the end parts of the wires in advance in the prior art is solved, the workers are prevented from inserting the end parts of the wires into wrong hole positions, the qualification rate of the produced connecting wires is guaranteed, the production efficiency is improved, and the labor cost is reduced.

With reference to fig. 12, the connection line has two connectors and a plurality of wires as an example for illustration in this embodiment, wherein before the connectors of the connection line and the plurality of wires are assembled, first, the first connection terminal of the first connector is inserted into the first detection seat, and after the first connection terminal is inserted into the first installation position of the first detection seat, in the depth direction of the first installation position, a projection of one first pin is located in one first hole location of the first connection terminal, so that the plurality of first pins correspond to the plurality of first hole locations one by one; similarly, a second connecting terminal of a second connector is inserted into the second detection seat, and after the second connecting terminal is inserted into a second mounting position of the second detection seat, the projection of one second pin is located in one second hole site of the second connecting terminal in the depth direction of the second mounting position, so that the plurality of second pins correspond to the plurality of second hole sites one to one.

Then, a corresponding computer program is introduced into the PLC controller according to the type and kind of the connecting wire to be processed, where the computer program may include the number of wires to be assembled and the corresponding relationship between the first pins on the first testing seat and the second pins on the second testing seat (i.e. the corresponding relationship between the first holes on the first connecting terminal and the second holes on the second connecting terminal is set), for example, the #1 pin on the first testing seat and the #2 pin on the second testing seat are set to correspond. In addition, in this embodiment, the two ends of each electric wire are respectively provided with a terminal, when the electric wire is assembled with the connecting terminal, the terminal at the end of the electric wire is inserted into the corresponding hole on the corresponding connecting terminal, and when the terminal at the end of the electric wire is inserted in place, the terminal can be electrically connected with a corresponding contact pin on the detection seat.

Then, the terminal wiring induction system is started, so that the PLC controller reads the computer program stored in the PLC controller, and executes step S11, obtains the control command, and controls the first indicator light and the second indicator light corresponding to the control command to emit light according to the control command. The corresponding first indicator lamp on the first detection seat and the corresponding second indicator lamp on the second detection seat are controlled to emit light according to the acquired control instruction, so that a worker is guided to insert the first end of the current wire to be assembled into a first hole position, corresponding to the first indicator lamp, on the first wiring terminal, and insert the second end of the current wire to be assembled into a second hole position, corresponding to the second indicator lamp, on the second wiring terminal.

The obtaining of the control command may be a first control signal generated by a control element connected to an input unit of the PLC controller, for example, a button connected to the input unit of the PLC controller, and the PLC controller obtains the first control signal once every time the button is pressed, so that the terminal wiring guidance system obtains the control command once. Or, the acquisition of the control instruction may be a second control signal generated by a soft contact inside the PLC controller, for example, when the first pin corresponding to the first light-emitting indicator lamp and the second pin corresponding to the second light-emitting indicator lamp are connected by a wire and are in a conducting state, the PLC controller may acquire a feedback signal, and at this time, the computer program stored in the PLC controller controls the soft contact inside the PLC controller to be closed once according to the acquired feedback signal, so as to simulate to press a button once, so that a worker does not need to actually press a button externally provided on the PLC controller, thereby better improving the production efficiency, and making the work of the terminal connection induction system more reliable.

Further, when the connecting line for assembly includes at least one multi-core wire, and the color of each sub-wire of the multi-core wire is different, the color sensor is required for assembly of the connecting line, and at this time, the acquisition of the control command may also be the first detection signal generated by the color sensor. For example, when the color sensor detects the color of the sub-line of the multi-core wire, a first detection signal corresponding to the color of the detected sub-line is generated and fed back to the PLC controller, so that the PLC controller controls a corresponding first indicator lamp on the first detection seat and a corresponding second indicator lamp on the second detection seat to emit light after comparing the acquired first detection signal with relevant parameters in a computer program stored in the PLC controller, thereby guiding a worker to insert two ends of each sub-line into corresponding hole sites on two connection terminals respectively.

After the first indicator light and the second indicator light corresponding to the acquired control instruction are illuminated, step S12 is executed to determine whether the first pin corresponding to the illuminated first indicator light and the second pin corresponding to the illuminated second indicator light are in a conducting state. If so, the current position of the electric wire to be assembled is proved to be correct, and step S13 is executed to obtain a feedback signal; otherwise, the position of the current wire connection to be assembled is proved to be wrong, and the step S12 is executed again to ensure that the next wire can be assembled after the position of the current wire connection to be assembled is correct.

When the position that the electric wire that waits to assemble at present connects is correct, this electric wire can make the first contact pin corresponding with luminous first pilot lamp and switch on with the corresponding second contact pin of luminous second pilot lamp to the PLC controller can acquire above-mentioned feedback signal. And after the PLC acquires the feedback signal, executing step S14, judging whether the assembly of all the wires of the connecting wire is finished, if so, finishing the assembly of the connecting wire, otherwise, returning to step S11 to carry out the assembly processing of the next wire.

The following exemplifies the operation method of the terminal connection induction system of the present embodiment.

For example, one: the connecting wire has two connectors and a plurality of electric wires, wherein, the length and/or the colour of a plurality of electric wires are all different, and a plurality of electric wires are all single core electric wires.

When the connectors of the connecting lines and the plurality of wires need to be assembled, first, the first wiring terminal of the first connector is mounted on the first detection seat, and the second wiring terminal of the second connector is mounted on the second detection seat.

And then, starting the terminal wiring induction system, wherein the PLC controls a first indicator lamp on the first detection seat to emit light and controls a second indicator lamp on the second detection seat corresponding to the first indicator lamp to emit light according to a computer program stored in the PLC. For example, a first indicator light #1 on the first detection seat emits light, and a second indicator light #2 on the second detection seat emits light, wherein the first indicator light corresponds to a first hole #1 on the first connection terminal and a first pin #1 on the first detection seat, and the second indicator light corresponds to a second hole #2 on the second connection terminal and a second pin #2 on the second detection seat. At this time, only the #2 second pin on the second detection seat communicates with the output unit of the PLC controller, and all the communication between the other second pins and the output unit of the PLC controller is cut off.

And then, the PLC controls a third indicator light of a first storage bin corresponding to the material supply device to emit light so as to guide a worker to take the electric wire in the first storage bin. It should be noted that, if the material supply device is not provided with an indicator light, but an automatic door is arranged at the bin opening of the storage bin, the PLC controller may control the automatic door at the bin opening of the storage bin corresponding to the material supply device to open.

Then, when the worker inserts the first end of the taken electric wire into the #1 first hole of the first connecting terminal and inserts the second end of the electric wire into the #2 second hole of the second connecting terminal, the #1 first contact pin on the first detection seat and the #2 second contact pin on the second detection seat are conducted, a feedback signal is formed and fed back to the PLC, and when the PLC judges that the connection of all the electric wires is not completed, the control steps are repeated to connect the next electric wire. For example, when a next wire needs to be connected to the #4 first hole of the first connection terminal and the #1 second hole of the second connection terminal, the PLC controller controls the #4 first indicator light on the first detection seat to emit light and controls the #1 second indicator light on the second detection seat to emit light.

When the worker inserts at least one end of the taken electric wire into the specified hole site, the PLC controller keeps the current state until the worker inserts the two ends of the taken electric wire into the corresponding hole sites respectively; certainly, as another optional processing mode, if the PLC controller detects a wrong hole location at the end of the wire through a computer program stored in the PLC controller, the PLC controller may control the terminal wiring guidance system to be in a locked state, so as to wait for the worker to perform subsequent processing before re-operating.

Example two is as follows: the connecting wire has two connectors and a plurality of wires, wherein one of the plurality of wires is a multi-core wire having, for example, four colors of red, black, blue, and green.

When the connectors of the connecting wires and the multi-core wires need to be assembled, firstly, the first wiring terminal of the first connector is installed on the first detection seat, and the second wiring terminal of the second connector is installed on the second detection seat.

And then, starting the terminal wiring induction system, transferring one sub-wire in the multi-core wire to the color sensor by a worker for detection, feeding a generated first detection signal back to the PLC by the color sensor, and controlling a first indicator lamp on the first detection seat to emit light and a second indicator lamp corresponding to the first indicator lamp on the second detection seat to emit light according to a computer program stored in the PLC. For example,

for example, when the currently detected sub-line is red, which corresponds to the #1 first indicator light on the first detection seat and the #2 second indicator light on the second detection seat, the PLC controller controls the #1 first indicator light on the first detection seat to emit light and controls the #2 second indicator light on the second detection seat to emit light according to the first detection signal fed back by the color sensor. The first indicator lamp corresponds to a #1 first hole on the first wiring terminal and a #1 first contact pin on the first detection seat, and the second indicator lamp corresponds to a #2 second hole on the second wiring terminal and a #2 second contact pin on the second detection seat. At this time, only the #2 second pin on the second detection seat communicates with the output unit of the PLC controller, and all the communications between the other second pins and the output unit of the PLC controller are blocked.

Then, when a worker inserts the first end of the red sub-wire into the #1 first hole of the first connecting terminal and inserts the second end of the red sub-wire into the #2 second hole of the second connecting terminal, the #1 first contact pin on the first detection seat and the #2 second contact pin on the second detection seat are conducted, a feedback signal is formed and fed back to the PLC, and the PLC repeats the control steps to connect the next wire when judging that the connection of all the wires is not completed. For example, when the color of the next sub-line is black, the black sub-line needs to be connected to the #4 first hole of the first connection terminal and the #1 second hole of the second connection terminal, and after the worker transfers the black sub-line to the color sensor for detection, the color sensor feeds back a first detection signal generated by the color sensor to the PLC controller, so that the PLC controller controls the #4 first indicator lamp on the first detection seat to emit light and controls the #1 second indicator lamp on the second detection seat to emit light according to a computer program stored in the PLC controller.

In addition, as for the connection of the other single-core electric wires in the connection line, the above example is referred to, and therefore, the description thereof will not be repeated.

Method for operating a terminal connection induction system

With reference to fig. 13, the working method of the terminal connection induction system of this embodiment is applied to the terminal connection induction system in the first embodiment or the third embodiment of the terminal connection induction system, and the working method is mainly used for controlling the terminal connection induction system to guide a worker to assemble a connection terminal of a connection line and a plurality of electric wires, so as to solve the problem that the worker needs to set a wire number tube or a label at the end of each electric wire in advance in the prior art, and avoid the worker from inserting the end of the electric wire into a wrong hole, thereby ensuring the qualification rate of the produced connection line, improving the production efficiency, and reducing the labor cost.

In the present embodiment, the connecting line has two connectors and a plurality of wires as an example, wherein the installation manner of the connecting terminals of the connectors and the corresponding detecting seats and the corresponding relationship between the pins of the two detecting seats are the same as the first embodiment of the operation method of the terminal connection guiding system, and therefore, the description thereof is not repeated here.

Next, the terminal wiring inducing system is activated, so that the PLC controller reads its own stored computer program, and performs step S21 to acquire a second detection signal of the second detection loop. And the acquisition of a second detection signal of the second detection loop is realized by the detection rod.

And then, executing a step S22, controlling a first indicator light and a second indicator light corresponding to the second detection signal to emit light according to the second detection signal, so as to guide a worker to respectively insert two ends of the tested wire into the hole sites corresponding to the two connection terminals.

Next, step S23 is executed to determine whether the first pin corresponding to the first indicator light emitting and the second pin corresponding to the second indicator light emitting are in a conducting state. If so, the current position of the electric wire to be assembled is proved to be correct, and step S24 is executed to obtain a feedback signal; otherwise, the position of the current wire connection to be assembled is proved to be wrong, and the step S23 is executed again to ensure that the next wire can be assembled after the position of the current wire connection to be assembled is correct.

When the position that the electric wire that waits to assemble at present connects is correct, this electric wire can make the first contact pin corresponding with luminous first pilot lamp and switch on with the corresponding second contact pin of luminous second pilot lamp to the PLC controller can acquire above-mentioned feedback signal. And after the PLC acquires the feedback signal, executing step S25, judging whether the assembly of all the wires of the connecting wire is finished, if so, finishing the assembly of the connecting wire, otherwise, returning to step S21 to carry out the assembly processing of the next wire.

The following exemplifies the operation method of the terminal connection induction system of the present embodiment. Example three: the connecting wire has two connectors and many electric wires, and wherein, the length and the colour of many electric wires are all the same, and the first end of many electric wires has all been inserted in the hole site that corresponds on the first binding post of first connector, forms semi-manufactured goods line between many electric wires and the first connector promptly. Thus, the third example can be regarded as assembling the semi-finished wire of the connecting wire and the second connector.

When a plurality of wires of the semi-finished wire of the connecting wire and the second connector need to be assembled, first, the first connection terminal of the first connector is mounted on the first detection seat, and the second connection terminal of the second connector is mounted on the second detection seat. At this time, since the first ends of the plurality of wires are all inserted into the corresponding first holes on the first connection terminal, the second ends of the plurality of wires need to be inserted into the corresponding second holes on the second connection terminal of the second connector one by one.

And then, starting the terminal wiring induction system, when the staff makes the second ends of the wires contact with the detection rods one by one, identifying which hole position on the second wiring terminal the second end of the wire needs to be inserted into by the detection rods through the second detection loop, and feeding back a second detection signal to the PLC controller, so that the PLC controller controls a corresponding first indicator lamp on the first detection seat to emit light, and controls a corresponding second indicator lamp on the second detection seat to emit light. For example, when the first end of the front wire is inserted into the #1 first hole of the first connection terminal, the PLC controller controls the #1 first indicator lamp on the first detection seat and the #2 second indicator lamp on the second detection seat to emit light, wherein the second indicator lamp corresponds to the #2 second hole on the second connection terminal and the #2 second pin on the second detection seat. At this time, only the #2 second pin on the second detection seat communicates with the output unit of the PLC controller, and all the communication between the other second pins and the output unit of the PLC controller is cut off.

And then, when the worker inserts the second end of the wire into the #2 second hole of the second connecting terminal, the #1 first contact pin on the first detection seat and the #2 second contact pin on the second detection seat are conducted, and a feedback signal is formed and fed back to the PLC controller, so that the PLC controller repeats the control steps to connect the next wire when judging that the connection of all the wires is not completed. And when the worker inserts at least one end of the wire to be taken into the specified hole site in a wrong way, the PLC controller keeps the current state until the worker inserts the two ends of the wire to be taken into the corresponding hole sites respectively.

It should be noted that, if there is a multi-core wire among the plurality of wires, the assembly process of the multi-core wire is the same as the second example in the first embodiment of the operation method of the terminal connection induction system, and therefore, a repeated description is not given here.

Third embodiment of method for operating terminal connection induction system

With reference to fig. 14, the working method of the terminal connection induction system of this embodiment is applied to the terminal connection induction system in the second embodiment or the third embodiment of the terminal connection induction system, and the working method is mainly used for controlling the terminal connection induction system to guide a worker to assemble a connection terminal of a connection line and a plurality of electric wires, so as to solve the problem that the worker needs to set a wire number tube or a label at the end of each electric wire in advance in the prior art, and avoid the worker from inserting the end of the electric wire into a wrong hole, thereby ensuring the qualification rate of the produced connection line, improving the production efficiency, and reducing the labor cost.

The present embodiment is exemplified by the case where the connection line has a single connector and a plurality of wires, wherein,

before the connector and the electric wires of the connecting wire are assembled, firstly, a wiring terminal of the connector is inserted into the detection seat, and after the wiring terminal is inserted into the installation position of the detection seat, the projection of one contact pin is positioned in one hole site of the wiring terminal in the depth direction of the installation position, so that the plurality of contact pins and the plurality of hole sites are in one-to-one correspondence.

Then, according to the model and the type of the connecting wire to be processed, a corresponding computer program is introduced into the PLC, and the computer program can comprise the quantity of the electric wires required to be assembled, the corresponding relation between the plurality of contact pins on the detection seat and the plurality of first storage bins of the material supply device and the like. In addition, in this embodiment, a terminal is disposed at an end portion of each electric wire to be connected, when the electric wire is assembled with the connection terminal, the terminal at the end portion of the electric wire is inserted into a corresponding hole on the corresponding connection terminal, and when the terminal at the end portion of the electric wire is inserted in place, the terminal can be electrically connected with a corresponding contact pin on the detection seat.

Then, the terminal wiring guidance system is started, so that the PLC controller reads the computer program stored in the PLC controller, and executes step S31, obtains the control instruction, and controls the first indicator light corresponding to the control instruction according to the control instruction. The corresponding first indicator lamp on the detection seat is controlled to emit light according to the acquired control instruction, so that a worker is guided to insert the end part of the current wire to be assembled into a hole position, corresponding to the first indicator lamp, on the wiring terminal. Here, the acquisition of the control command is the same as the operation method of the terminal connection induction system in the first embodiment, and therefore, the description thereof will not be repeated. Further, when the assembled connection line includes at least one multicore wire, the assembly manner of the multicore wire is similar to the principle of the assembly manner of the multicore wire in the first embodiment of the operation method of the terminal connection induction system, and therefore, the description will not be repeated.

After the first indicator light corresponding to the obtained control instruction is lighted, step S32 is executed to determine whether the contact pin of the pin corresponding to the lighted first indicator light and the sensing pin are in a conducting state. If so, the current position of the electric wire to be assembled is proved to be correct, and step S33 is executed to obtain a feedback signal; otherwise, the position of the current wire connection to be assembled is proved to be wrong, and the step S32 is executed again to ensure that the next wire can be assembled only after the position of the current wire connection to be assembled is correct.

When the position that the electric wire that waits to assemble connects at present is correct, contact pin and the response needle to the contact pin that this electric wire corresponds can contact each other in order to become the conducting state to the PLC controller can acquire above-mentioned feedback signal. And after the PLC acquires the feedback signal, executing step S34, judging whether the assembly of all the wires of the connecting wire is finished, if so, finishing the assembly of the connecting wire, otherwise, returning to step S31 to carry out the assembly processing of the next wire.

The following exemplifies the operation method of the terminal connection induction system of the present embodiment. Example four: the connecting wire has a single connector and a plurality of wires.

When the connector of the connecting line and a plurality of wires need to be assembled, firstly, the wiring terminal of the connector is installed on the detection seat. And then, starting the terminal wiring induction system, and controlling an indicator lamp on the detection seat to emit light by the PLC according to a computer program stored in the PLC. For example, the #1 first indicator light on the current detection seat emits light, and in this embodiment, it is assumed that the first indicator light corresponds to the #1 pin, the #2 first storage bin of the material supply device, and the #1 hole of the connection terminal, respectively.

And then, the PLC controls a second indicator light of a #1 first storage bin on the material supply device to emit light so as to guide a worker to take the electric wire in the first storage bin. When the worker inserts the end of the taken electric wire into the hole #1 of the connecting terminal,

and the contact pin and the induction pin of the #1 contact pin on the front detection seat are contacted and conducted, and form a feedback signal to be fed back to the PLC, so that the PLC repeats the control steps to connect the next electric wire when judging that the connection of all the electric wires is not completed. When the end of the wire taken by the worker is inserted into the specified hole, the PLC keeps the current state until the end of the wire taken by the worker is inserted into the corresponding hole; of course, as other optional processing modes, if the PLC controller detects a wrong hole at the end of the wire through a computer program stored in the PLC controller, the PLC controller may control the terminal wiring guidance system to be in a locked state, so as to wait for the worker to perform subsequent processing before re-operating.

Finally, it should be emphasized that the above-described preferred embodiments of the present invention are merely examples of implementations, and it should be understood that various changes and modifications may be made by those skilled in the art, and any changes, equivalents, improvements and the like, which fall within the spirit and principle of the present invention, should be included in the scope of the present invention.
