Abstract

The present invention belongs to the technical field of electrical components, and specifically relates to a device for improving the operation of an electromagnetic actuator, and more particularly to a control device and a working method for an intelligent manufacturing actuator.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] After research, it was found that the dual-coil electromagnetic actuator in the related art uses the same current to drive the two coils of the actuator when driving. When switching the power supply, the magnetic force generated by the previous coil has not completely disappeared, and there is still attraction to the actuator's battery core, which causes the action of the actuator to lag when switching, resulting in a delay in the actuator's response. Therefore, how to solve the impact of the magnetic force generated by the previous coil on the drive of the next coil when switching is the problem and purpose to be solved by the present invention.

[0024] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0025] Based on the above research, the embodiments of the present disclosure provide a control device and a working method for an intelligent manufacturing actuator, which controls the switched coil with a larger current, thereby offsetting the magnetic force generated by the previous coil, allowing the actuator to move quickly, improving the response speed of the actuator, and thus reducing the difference in response speed of the actuator during startup and switching.

[0026] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0028] See also Figure 1 and Figure 2 , at least one embodiment provides a control device for an intelligent manufacturing actuator, including the following structure.

[0029] The actuator body includes an iron core and two coils, and the two coils are respectively arranged at the two ends of the iron core. Each coil generates a magnetic field through current, thereby driving the iron core to move. The two coils control different directions or forces respectively, which can provide higher stability and accuracy.

[0030] A power supply module is electrically connected to the two coils and is used to supply power to the two coils. The two coils are supplied with power by the power supply module, and the energy of the power supply is controlled under the control of the controller.

[0031] The controller is electrically connected to the power supply module and is configured to control the power supply module to continuously supply power to one of the coils with the first energy according to the received power supply instruction; and when a switching instruction is received, the power supply to the current coil is stopped, and the other coil is supplied with the second energy for a preset time, and then the energy is reduced to the first energy to continuously supply power to the coil, thereby completing the power supply switching.

[0032] Specifically, if Figure 1 and Figure 2 As shown, the two coils are coil L1 and coil L2. When coil L1 is energized, it drives the iron core to rise, and when coil L2 is energized, it drives the iron core to fall. The distance the iron core moves is related to the amount of energy of the energization.

[0033] The magnetic force of the electromagnetic field generated by the corresponding coil when powered by the first energy is smaller than the magnetic force of the electromagnetic field generated by the corresponding coil when powered by the second energy. The magnetic force generated by the previous coil is offset by the larger second energy, so that the actuator moves quickly and the response speed of the actuator is improved, thereby reducing the difference in the response speed of the actuator when starting and switching.

[0034] Specifically, the continuous power supply with the first energy, that is, the continuous power supply with the preset voltage and the first current, is performed to meet the action requirements of the core.

[0035] The preset time of supplying power with the second energy, that is, the preset time of supplying power with the preset voltage and the second current. The preset voltage and the second current set according to the demand are used to supply power to meet the action requirements of the iron core, wherein the first current is smaller than the second current. Since the first current is smaller than the second current, when switching, the lagging magnetic force of the previous coil is offset by a stronger magnetic force, thereby improving the response speed during switching. The preset time is obtained based on experiments, that is, the response time of the two actions is made the same.

[0036] Please continue reading Figure 1 and Figure 2 The power supply module includes a power supply unit and a capacitor unit. The capacitor unit consumes the residual electric energy when the coil is powered off and charges the next working coil, thereby improving the response speed of the next working coil and reducing energy loss.

[0037] The controller is electrically connected to the power supply unit and the capacitor unit respectively. The control principles of the power supply unit and the capacitor unit are as follows.

[0038] Control principle of the power supply unit: the controller is configured to control the power supply unit to continuously supply power to one of the coils with the first energy according to the received power supply instruction; and when a switching instruction is received, the power supply to the current coil is stopped, and the other coil is supplied with the second energy for a preset time, and then the energy is reduced to the first energy to continuously supply power to the coil, thereby completing the power supply switching.

[0039] Control principle of the capacitor unit: the controller is also configured to control the capacitor unit to charge with the residual electric energy in the current coil that stops powering when receiving a switching instruction, thereby accelerating the disappearance of the electromagnetic field of the current coil, and control the capacitor unit to discharge while powering the other coil with the second energy, thereby powering the other coil and accelerating the generation of the electromagnetic field of the other coil.

[0040] Please continue reading Figure 1 In some embodiments, the power supply unit includes a power supply A and a power supply B, and the power supply A and the power supply B are used to supply power to the corresponding coils separately.

[0041] See also Figure 2 In some embodiments, the power supply unit includes a power supply and a contactor, and the controller controls the conduction direction of the contactor to supply power to the coil L1 and the coil L2.

[0042] It should be noted that the charging time of the capacitor unit is shorter than the power supply switching time of the coil L1 and the coil L2, that is, the time for the residual electric energy in the coil to be consumed is shorter than the power supply switching time.

[0043] See also Figure 3 , the capacitor unit includes the following structure.

[0044] The supercapacitor C is charged and discharged to increase the speed at which the magnetic forces of the two coils are generated and disappeared.

[0045] Four switch tube groups, and the two ends of the two coils are connected to the two ends of the super capacitor C through the corresponding switch tube groups; the controller is electrically connected to the four switch tube groups, and is configured to control the on-off state of the four switch tube groups according to the switching instructions to control the charging and discharging of the super capacitor C. The on-off of the super capacitor C and the coil L1 and the coil L2 is controlled by the four switch tube groups, and a corresponding charging and discharging circuit is formed.

[0046] Specifically, the controller controls the on / off states of the four switch tube groups according to the switching instructions to control the charging and discharging of the super capacitor C, that is: When a switching instruction is received, the switch tube groups at both ends of the coil that is currently stopped from being powered are controlled to be turned on with the supercapacitor C, and the residual electric energy in the current coil that is currently stopped from being powered is used to charge, thereby accelerating the disappearance of the electromagnetic field of the current coil; and after the charging is completed, the switch tube groups at both ends of the other coil are controlled to be turned on with the supercapacitor C, so as to power the other coil and accelerate the generation of the electromagnetic field of the other coil.

[0047] The meaning of charging completion is that the residual electric energy in the current coil that stops supplying power is consumed. In actual control, the switching of charging and discharging is completed by setting the conduction time.

[0048] It should be noted that the switch tube group includes two switch tubes, and the two switch tubes in each switch tube group are turned on in opposite directions. The controller is electrically connected to the control pins P1-P8 of the switch tubes to control the on and off of the corresponding switch tubes.

[0049] When the coil L1 is discharged, the switch tubes Q2 and Q6 in the switch tube group are turned on. The circuit diagram when turned on is as follows: Figure 4 As shown, the current direction is shown as I1. When the coil L1 is charged, the switch tubes Q1 and Q5 in the switch tube group are turned on. The circuit diagram when turned on is shown as follows Figure 5 As shown, the current direction is shown as I2.

[0050] Please continue reading Figure 3 The capacitor unit further includes: a discharge management chip U6, and the discharge management chip U6 is electrically connected to both ends of the super capacitor C, and is configured to discharge after detecting that the super capacitor is fully charged. Among them, the chip model of the discharge management chip U6 is BW6101. After the super capacitor C is fully charged, the discharge management chip U6 is used to discharge to prevent the super capacitor C from being overcharged.

[0051] See also Figure 6 At least one embodiment further provides a working method for a control device for an intelligent manufacturing actuator as described above, wherein when switching the action of the actuator, after supplying power to another coil with the second energy for a preset time, the power supply is reduced to the first energy to continuously supply power to the coil, thereby completing the power supply switching. When the first energy is used to supply power, the magnetic force of the electromagnetic field generated by the corresponding coil is smaller than the magnetic force of the electromagnetic field generated by the corresponding coil when the second energy is used to supply power, thereby offsetting the magnetic force generated by the previous coil, causing the actuator to move quickly, thereby improving the response speed of the actuator, and reducing the difference in response speed of the actuator during startup and switching.

[0052] Specifically, the working method includes: S110: Receive a power supply instruction.

[0053] Specifically, when the actuator is required to work, the controller receives a power supply instruction.

[0054] 120: According to the power supply instruction, continuously supply power to one of the coils with the first energy.

[0060] S150: According to the switching instruction, after supplying power to another coil with the second energy for a preset time, the energy is reduced to the first energy to continuously supply power to the coil, thereby completing the power supply switching.

[0061] Specifically, the magnetic force of the electromagnetic field generated by the corresponding coil when powered by the first energy is smaller than the magnetic force of the electromagnetic field generated by the corresponding coil when powered by the second energy, thereby offsetting the magnetic force generated by the previous coil, causing the actuator to move quickly and improving the response speed of the actuator, thereby reducing the difference in response speed of the actuator during startup and switching.

[0062] In some embodiments, the power supply module includes a power supply unit and a capacitor unit, and the controller is electrically connected to the power supply unit and the capacitor unit, respectively.

[0063] The working method also includes: When the power supply to the current coil is stopped according to the switching instruction, the capacitor unit is controlled to charge the residual electric energy in the current coil to accelerate the disappearance of the electromagnetic field of the current coil. The residual electric energy of the current coil is consumed by the capacitor unit to accelerate the disappearance of the electromagnetic field of the current coil and reduce the impact on another coil.

[0064] While supplying power to another coil with the second energy, the capacitor unit is controlled to discharge, supplying power to another coil, accelerating the generation of the electromagnetic field of another coil, charging the next coil, improving the response speed of the next coil, and reducing energy loss.

[0065] In some embodiments, the continuous power supply with the first energy is to provide continuous power supply with a preset voltage and a first current; the power supply with the second energy for a preset time is to provide power supply with a preset voltage and a second current for a preset time; wherein the first current is smaller than the second current.

When switching the action of the actuator, after supplying power to another coil with the second energy for a preset time, the energy is reduced to the first energy to continuously supply power to the coil, thereby completing the power supply switching. The magnetic force of the electromagnetic field generated by the corresponding coil when powered by the first energy is smaller than the magnetic force of the electromagnetic field generated by the corresponding coil when powered by the second energy, thereby offsetting the magnetic force generated by the previous coil, causing the actuator to move quickly, improving the response speed of the actuator, and reducing the difference in response speed of the actuator during startup and switching.
