Detailed Description

To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

According to the utility model discloses an embodiment provides a detection device of motion, as shown in fig. 1 the utility model discloses a detection device of motion's a schematic structure diagram of an embodiment. The detection device of the movement mechanism may include: a bit signal detection unit 31 and a controller 33.

In one example, the in-place signal detecting unit 31 may form a closed circuit 30 (see, for example, the examples shown in fig. 3 to 5) with the moving mechanism 32 (see, for example, the example shown in fig. 4), and may be configured to obtain a first state change signal of the closed circuit 30 when the moving mechanism moves to a preset position, as an in-place signal when the moving mechanism moves to the preset position.

For example: the loop signal is used for signal detection and control, so that the common inductive switches (such as a proximity switch, a photoelectric sensor, an optical fiber sensor and the like) can be effectively replaced, and signals (such as a contact in-place signal, a detection signal and the like) can be directly acquired in the contact process.

Alternatively, the bit signal detecting unit 31 may include: a serial circuit.

For example: referring to the examples shown in fig. 4 and 5, the control and detection of the in-place signal are realized by using a closed circuit (i.e., a loop); the state change of the circuit requires certain external action; the control system is reversible.

Therefore, the detection and control device is applicable to detection and control of various motion mechanisms through closed circuits in various forms, and is wide in application range, good in control flexibility and high in universality.

Optionally, the first state change signal may include: if the initial state of the closed circuit 30 when the moving mechanism does not move to the preset position is a closed loop state, when the moving mechanism moves to the preset position, the closed circuit 30 is opened and is in an open circuit state.

Alternatively, the first state change signal may further include: if the initial state of the closed circuit 30 is the open circuit state, when the moving mechanism moves to the preset position, the closed circuit 30 is closed and is in the closed loop state.

For example: if it is necessary to acquire a control signal according to a process of changing the state of the entire circuit from open to closed, the above process (e.g., from "on" to "off") may be reversed (e.g., from "off" to "on"), and information control may also be realized.

From this, through can be according to the initial state of the nimble signal that sets up of actual demand, it is good to use the convenience, and user experience is good.

For example: the mechanism (such as a motion mechanism) action and a signal (such as an in-place signal) are skillfully combined, the in-place signal monitoring is realized in the butt joint process by directly utilizing the in-place signal, the method is simple and convenient, and the method can be used in occasions where the human body is not suitable for direct operation (such as automatic pressure resistance of products, connection of high-voltage wires, mechanism conduction detection in severe environments of high temperature, toxicity, corrosivity, radioactivity and the like).

Therefore, the corresponding signals are directly acquired in the running process of the movement mechanism, and the running process is controlled according to the signals, so that the acquisition mode and the control mode of the signals are simple and convenient, the reliability is high, and the humanization is good.

In one example, the controller 33 may be configured to determine that the moving mechanism has been operated to the preset position according to the in-position signal.

For example: the method can be used for detecting and processing the in-place signals in severe environment.

Therefore, by acquiring and processing the loop signal, the method has the advantages of convenience in control, compact structure, no need of additionally adding an auxiliary control mechanism and the like, and is good in reliability.

Alternatively, the controller 33 may include: at least one of PLC, MCU, singlechip, DSP treater.

For example: the control system can comprise a PLC. After the original circuit state changes, a prompt signal is sent to the PLC, so that the movement mechanism stops advancing, or mechanical equipment gives an alarm to remind after the original circuit state changes.

Therefore, the controller in various forms is beneficial to improving the convenience of control and the flexibility of use, and the reliability is high.

In an alternative embodiment, the controller 33 may be further configured to control the moving mechanism to perform a next operation after the moving mechanism is determined to have been operated to the preset position.

For example: the in-place signal can be used as a reference for the next action.

Therefore, the next control is carried out based on the determined in-place signal, and the accuracy and the reliability of the next control are improved.

In an alternative embodiment, the in-position signal detecting unit 31 may be further configured to acquire a second state change signal of the closed circuit 30, which is opposite to the first state change signal, when the moving mechanism is out of the preset position, as an out-position signal that the moving mechanism is out of the preset position.

Accordingly, the controller 33 may be further configured to determine that the moving mechanism has departed from the preset position according to the deviation signal.

For example: referring to the examples shown in fig. 3 and 4, in the process of approaching and butting the moving point and the object, the state of the original circuit is changed, so that the control system obtains a feedback signal; and in the process that the moving point is far away from the object, the circuit state is changed again, and the control system acquires a feedback signal again.

Therefore, the comprehensive control and safety of the motion mechanism in the operation process can be improved by off-position control.

In an alternative embodiment, the controller 33 may be further configured to control the moving mechanism to perform a next operation after the moving mechanism is disengaged from the preset position after determining that the moving mechanism is disengaged from the preset position.

For example: the off-bit signal can be used as a reference for the next action.

Therefore, the next control is carried out based on the determined off-position signal, and the accuracy and the reliability of the next control are improved.

In an alternative embodiment, the number of the moving mechanisms forming the closed circuit 30 with the in-position signal detecting unit 31 may be at least one.

Accordingly, when the number of the motion mechanisms is more than one, the controller 33 may be further configured to control the operation of the at least one motion mechanism according to the in-position signal of the at least one motion mechanism or the out-of-position signal of any one of the at least one motion mechanism.

For example: and can also be used for safety protection and the like.

For example: in the aspect of safe use of equipment, the control system can also be applied to realize multipoint safety protection, and as long as abnormality occurs at one position, the control system can acquire signals to ensure the operation safety.

For example: referring to the example shown in fig. 5, in terms of the operation safety of the equipment, the control system can also be used to realize multipoint safety protection, and as long as an abnormality occurs at one place, that is, one or more places are changed from closed to open, the whole loop is changed from closed to open, and the corresponding control system acquires a signal, so that remote control and multipoint control can be realized, and the operation safety can be ensured.

For example: referring to the example shown in fig. 5, in terms of safety, the circuit state at some point (or some points) of the serial circuit can be changed to affect the whole circuit, so that the moving part is stopped or decelerated, and the like, thereby ensuring safety.

Therefore, the system is beneficial to improving the reliability and safety of the operation of the system where the plurality of motion mechanisms are located by monitoring the plurality of motion mechanisms at the same time, and the control mode is simple and convenient.

In an alternative embodiment, referring to the example shown in fig. 2, the method may further include: a display unit 34.

In one example, the display unit 34 may be configured to display at least one of the in-place signal and the out-of-place signal.

Therefore, through the display of the positioning signal, the off-position signal and the like, specific information can be displayed more intuitively, and the use experience of a user and the running safety of the motion mechanism are further improved better.

Through a large number of tests, the technical scheme of the embodiment is adopted, and signals (such as contact in-place signals, detection signals and the like) are directly obtained in the contact process of the movement mechanism, so that the method can be used for detecting and processing in-place signals in severe environment; the device has the advantages of convenient control, compact structure, no need of additionally adding an auxiliary control mechanism and the like, and has good reliability.

According to the utility model discloses an embodiment still provides a motion corresponding to motion's detection device. The motion mechanism may include: the detection device of the movement mechanism.

In an alternative embodiment, the method may further include: and (4) making a voltage-resistant grounding device.

In one example, the voltage-withstanding grounding apparatus may include: a feeler lever 11; the feeler lever 11 forms a closed circuit 30 with the control device of the kinematic mechanism; when the contact rod 11 moves to a preset position, the closed circuit 30 generates the first state change; when the detection device of the movement mechanism is further configured to obtain a second state change signal of the closed circuit 30, the closed circuit 30 generates the second state change when the feeler lever 11 is disengaged from the preset position.

Therefore, a closed circuit is formed by the feeler lever and the detection device, whether the feeler lever moves in place or leaves can be detected, and the detection is convenient and reliable.

In one example, the voltage withstanding grounding apparatus may further include: the fixed ring 12, the pretension spring 13, the feeler lever guide sleeve 15, the clutch piece 19, the 1 st loop terminal 17 and the 2 nd loop terminal 20. The fixing ring 12, the pre-tightening spring 13 and the feeler lever guide sleeve 15 can be arranged on the periphery of the feeler lever 11 in a matching manner, and the fixing ring 12 and the feeler lever guide sleeve 15 can be positioned at two ends of the pre-tightening spring 13.

Optionally, the 1 st loop terminal 17, the 2 nd loop terminal 20, the clutch block 19 and the power supply circuit form another closed circuit 30.

For example: the fixed ring (12) and the pre-tightening spring (13) can increase the pre-tightening force, so that the circuit state cannot be easily changed, and the fixed ring and the pre-tightening spring are an auxiliary mechanism formed by another closed loop 30.

For example: the feeler lever guide sleeve 15 can reduce sliding resistance and ensure smooth sliding, and is an auxiliary mechanism for smoothly changing the state of the other closed loop 30 under the satisfied condition (for example, greater than the pre-tightening force of a spring).

Optionally, when the feeler lever 11 moves to another preset position, the pre-tightening spring 13 is compressed, so that the feeler lever 11 and the feeler lever guide sleeve 15 slide relatively, and another first state change occurs in the another closed circuit 30.

Optionally, when the feeler lever 11 has been disengaged from the other preset position, the compression of the pre-tightening spring 13 is restored, so that the relative sliding between the feeler lever 11 and the feeler lever guide sleeve 15 is restored, and the other closed circuit 30 undergoes the other second state change.

Therefore, through another closed circuit based on the pre-tightening spring, whether the touch rod is subjected to another in-place or another out-of-place detection or not can be detected through the compression and the extension of the pre-tightening spring, the operation process is safe and reliable, and the use convenience of a user is good.

In one embodiment, fig. 3 may show a common normally closed circuit.

In one example, the normally closed circuit may include: a power supply E, a first indicator light (e.g., load) L1, a second indicator light L2, and a normally closed contact K1.

For example: referring to the example shown in fig. 3, the circuit is normally closed and when the switch is open, the circuit is open. The change in state may provide a signal to a control unit (e.g., controller 33) and may also provide an indication.

In one embodiment, FIG. 4 may show a closed circuit including a motion mechanism.

In one example, the closed circuit may include: a power source E, a first indicator light L1 and a movement mechanism.

In one example, the motion mechanism may include: the device comprises a feeler lever 11, a fixed ring (used for adjusting the pretightening force of a pretightening spring) 12, a pretightening spring 13, a pretightening cushion block 14, a feeler lever guide sleeve 15 and a guide sleeve mounting block 16; a 1 st loop terminal 17, a 1 st insulating sleeve 18, a clutch block 19, a 2 nd loop terminal 20, a 2 nd insulating sleeve 21, a lock nut 22, and other peripheral component interfaces 23, and the like.

For example: referring to the example shown in fig. 4, during the approaching and docking process of the contact rod 11 with an object (e.g., an object at a preset position), the originally closed loop is opened, and the control system (e.g., the controller 33) acquires a signal (i.e., a loop open signal, which may indicate that the contact rod 11 is in contact with the object in place) and indicates the next action.

For example: during the process of the stylus 11 moving away from the object, the otherwise open circuit is reclosed, and the control system (e.g., controller 33) obtains a signal (i.e., a circuit closed signal, which may indicate that the stylus 11 has been moved away from the object) and indicates a further action.

Therefore, the mechanism (such as a motion mechanism) action and a signal (such as an in-place signal) can be skillfully combined, the in-place signal monitoring is realized in the butt joint process by directly utilizing the in-place signal, the method is simple and convenient, and the method can be used in occasions where the human body is not suitable for direct operation (such as automatic voltage resistance of products, connection of high-voltage wires, mechanism conduction detection in severe environments of high temperature, toxicity, corrosivity, radioactivity and the like).

In one example, referring to the example shown in fig. 4, when the mechanism (e.g., the moving mechanism) hits an object during the forward process, the pre-tightening spring is further compressed, the feeler lever 11 and the feeler lever guide sleeve 15 slide relatively, the loop where the 1 st loop terminal 17 and the 2 nd loop terminal 20 are located is disconnected, and the control system (e.g., the controller 33) acquires a in-position signal that the feeler lever 11 has hit the object and indicates the next action; when the mechanism (e.g., the kinematic mechanism) is retracted, the pretensioned springs gradually return to their extended positions, the circuit is again switched from the open state to the closed state, the circuit is again switched to the closed state, and the control system (e.g., the controller 33) will obtain a signal that the feeler lever has been disengaged and indicate the next action.

For example: the feeler lever 11 and the feeler lever guide sleeve 15 can slide, the sliding force is required to be as small as possible, and the guide sleeve (namely the feeler lever guide sleeve 15) can be replaced by a linear bearing, a copper sleeve, a steel sleeve, a non-metal sleeve and the like on the premise of not influencing the use effect and the safety.

Optionally, the guide sleeve can be a standard component (linear bearing, guide sleeve and the like) according to actual requirements, and can also be machined.

For example: the position of the fixing ring 12 can be adjusted to determine the proper spring (for example, the pre-tightening spring 13) pre-tightening force, and the 1 st insulating sleeve 18 and the 2 nd insulating sleeve 21 have the functions of disconnecting the butting mechanism from the signal circuit, have no influence on each other and allow the integrated structure to be manufactured.

Alternatively, the insulating sleeve may be made in one piece, but is required to facilitate assembly of other mechanisms.

Alternatively, the insulating sleeve may be made integral with the clutch block, the lock nut, or the like.

Alternatively, the feeler lever may be other parts, mechanisms, etc. that slide relative to the guide sleeve.

For example: the front end of the feeler lever can be made into a proper shape according to the structure of a product, and the tail end of the feeler lever can be directly connected with a lead and other mechanisms.

For example: the size of the pretightening force of the spring can be adjusted by adjusting the position of the fixing ring, and the circuit needs to be ensured to be in a closed state until the state is changed by external force.

Optionally, the pre-tightening force of the spring can be selected according to motion indexes such as speed and acceleration of the docking mechanism and indexes such as pressure resistance of a tested product, and no mandatory requirement is made. For example: when the starting acceleration of the docking mechanism is larger, the pretightening force can be properly adjusted to ensure that the state of a loop before docking is not changed; correspondingly, when the pressure resistance of the tested product is poor, the pretightening force can be properly reduced, and the product is ensured not to be damaged.

For example: when the two points need to be considered simultaneously, the acceleration time can be properly prolonged, the acceleration is gentle, and the requirement on the pretightening force is reduced.

In one example, referring to the examples shown in fig. 3 and 4, in the process of approaching and butting the moving point and the object, the state of the original circuit is changed, so that the control system obtains a feedback signal; when the moving point is far away from the object, the circuit state is changed again, so that the control system acquires a feedback signal again (the signal can be used as a reference for the next action).

The circuit is divided into a closed circuit, which is also called a closed loop, and an open circuit, which cannot be called a loop because it is open, but can be called an electric circuit.

In one particular example, the action points may include the following features:

the method comprises the steps of firstly, having certain strength and rigidity; the movement can directly influence the change of the circuit state; and a certain external action is required for changing the circuit state through the moving point.

In one embodiment, the control system can also be used for equipment safety, multi-point safety protection is realized, and the control system can acquire signals to ensure operation safety as long as abnormality occurs at one position.

Referring to the example shown in fig. 5, in terms of the operation safety of the equipment, the control system can also be used to realize multipoint safety protection, and as long as an abnormality occurs at one place, that is, one or more places are changed from closed to open, the whole loop is changed from closed to open, and the corresponding control system acquires a signal, so that remote control and multipoint control can be realized, and the operation safety can be ensured. The number of the normally closed switches in fig. 5 can be determined according to actual needs.

In one example, both fig. 4 and fig. 5 are used to facilitate a closed circuit (i.e., a loop) to control and detect the in-place signal; the state change of the circuit requires certain external action; the control system is reversible.

Similarly, if it is necessary to obtain a control signal according to the process of changing the state of the whole circuit from open to closed, the above process (for example, from "on" to "off") can be reversed (for example, from "off" to "on"), and information control can be realized.

In one example, in the process of detecting and controlling the circuit signal, if the initial state is the open state, the circuit cannot be called a loop, and only the circuit can be called.

In one example, referring to the example shown in fig. 5, in terms of safety, the circuit state at some point (or some points) of the serial circuit can be changed to affect the whole circuit, so that the moving part is stopped or decelerated, and the like, thereby ensuring safety.

Since the processing and functions of the motion mechanism of this embodiment are basically corresponding to the embodiments, principles and examples of the devices shown in fig. 1 to fig. 2, the description of this embodiment is not detailed, and reference may be made to the related descriptions in the foregoing embodiments, which are not repeated herein.

Through a large amount of experimental verifications, adopt the technical scheme of the utility model, through utilizing return circuit signal to carry out signal detection and control, can effectively replace inductive switch commonly used, can be arranged in safety protection, the security is good.

According to the utility model discloses an embodiment still provides a detection system of motion corresponding to motion. The detection system of the movement mechanism may include:

at step S110, the moving mechanism 32 (see, for example, the example shown in fig. 4) and the in-place signal detection unit 31 described above are formed into a closed circuit 30 (see, for example, the examples shown in fig. 3 to 5), and when the moving mechanism moves to a preset position, a first state change signal of the closed circuit 30 is acquired as an in-place signal of the moving mechanism running to the preset position.

At step S120, it is determined that the moving mechanism has been operated to the preset position according to the in-place signal.

In an alternative embodiment, in combination with step S120, the method may further include: and after the movement mechanism is determined to operate to the preset position, controlling the movement mechanism to perform the next operation after the movement mechanism is operated to the preset position in a preset manner.
