[0002] In modern industrial production, assembly line equipment is key to improving production efficiency and product quality. However, with rising energy costs and growing awareness of environmental protection, effectively reducing energy consumption has become a critical issue for companies.

[0047] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0048] The embodiment of the present invention proposes an energy-saving and consumption-reducing system for automated assembly line production equipment. In order to solve the shortcomings of the electrical control system in the prior art in terms of energy saving and consumption reduction, especially when the production line is at a standstill or operating at low load, the technical effect of still maintaining a high energy consumption level is achieved.

[0049] To better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0050] Example 1

[0051] See also Figure 1 , an energy-saving and consumption-reducing system for automated assembly line production equipment according to an embodiment of the present utility model comprises:

[0052] A three-phase five-wire circuit 1, a starting control circuit 2, an energy-saving control circuit 3, a low-power load circuit 4, and a high-power load circuit 5.

[0053] The starting control circuit 2 , the energy-saving control circuit 3 , the low-power load circuit 4 , and the high-power load circuit 5 are electrically connected to the three-phase five-wire circuit 1 , respectively.

[0054] The energy-saving control circuit 3 includes: a second switching power supply, a first button switch, and a second relay KA2.

[0055] The second relay KA2 includes: a coil and a normally open point.

[0056] The first end, second end, and third end of the second switching power supply are electrically connected to the third phase L3, the neutral wire N1, and the ground wire PE in the three-phase five-wire circuit, respectively; the coil of the first push button switch and the second relay KA2 are connected in series in a loop formed by the fourth end and the fifth end of the second switching power supply.

[0057] In this embodiment, the second switching power supply refers to a power supply used to prepare and check the system before the energy-saving and consumption-reducing system officially starts operating, for example, including preheating certain components, initializing the system, or performing safety checks.

[0058] The energy-saving control circuit 3 further includes: a second AC contactor KM2.

[0059] The second AC contactor KM2 includes a coil, a normally open contact, and a normally closed main contact.

[0060] In a specific implementation process, the normally open contact of the second AC contactor KM2 is not connected to the energy-saving and consumption-reducing system of this embodiment.

[0061] The coil of the second AC contactor KM2 is connected in series with the normally open point of the second relay KA2 ; the normally open point of the second relay KA2 is electrically connected to the third phase L3 of the three-phase five-wire circuit 1 and the neutral line N1 .

[0062] During the specific implementation process, the starting control circuit 2 is used to start the entire energy-saving and consumption-reducing system; the energy-saving control circuit is used to reduce energy consumption during non-production periods; the low-power load circuit is used to provide continuous power supply for components that need to work for a long time; and the motor high-power load circuit provides the power required for high-energy-consuming equipment such as motors to work.

[0063] The normally closed main contact of the second AC contactor KM2 is connected in series to the high-power load circuit 5.

[0064] When the first push button switch is closed, the second AC contactor KM2 is activated, cutting off the power supply to the high-power load circuit, while the low-power load circuit is powered normally.

[0065] In the specific implementation process, when the first button switch is closed, the second AC contactor KM2 is activated, and its normally closed main contact is disconnected, cutting off the power supply to the high-power load circuit 5, thereby significantly reducing energy consumption during non-production periods or when high-energy-consuming equipment is not required to work.

[0066] Through a simple first-button switch, you can switch from normal operation to energy-saving mode. The operation is very intuitive and simple, which reduces complicated operating steps and improves the user-friendliness of the energy-saving and consumption-reduction system.

[0067] Furthermore, the AC contactor is designed to withstand frequent on-off operations and is suitable for use in industrial production line environments.

[0068] For example, the low-power load circuit is before the energy-saving control circuit, such as the components of the control card data acquisition system that need to run for a long time, and the high-power load circuit is after the energy-saving control circuit. When the entire assembly line production equipment is completed, the entire equipment is in standby state, but due to the special characteristics of some components, the entire machine cannot be powered off, which requires continuous power supply to extend its life. At this time, press the first button switch, and the motor and other high-power components in the high-power load circuit 5 will lose power. When production is needed, turn on the first button switch again, and normal operation will be restored.

[0069] In this embodiment, the startup control circuit 2 includes:

[0070] A first switching power supply, a key switch, a start button, a first relay KA1 and a first AC contactor KM1.

[0071] The first relay KA1 includes: a coil and a normally open point.

[0072] The first AC contactor KM1 includes: a coil, a normally open point, a normally open main contact, and a normally closed contact.

[0073] In a specific implementation process, the normally closed contact of the first AC contactor KM1 is not connected to the energy-saving and consumption-reducing system in this embodiment.

[0074] The first, second, and third terminals of the first switching power supply are electrically connected to the third phase L3, the neutral wire N1, and the ground wire PE in the three-phase five-wire circuit 1, respectively; the key switch, the start button, and the coil of the first relay KA1 are connected in series in a loop formed by the fourth and fifth terminals of the first switching power supply.

[0075] In this embodiment, the first switching power supply is a post-startup switching power supply, which refers to the power supply after the energy-saving and consumption-reducing system in this embodiment is started and enters a normal operating state. At this time, all loads will receive power supply.

[0076] In the specific implementation process, after the main switch QF is closed and the start button is pressed, the first AC contactor KM1 is activated and the entire energy-saving and consumption-reducing system enters the full-power operation state. At this time, both the low-power load circuit and the high-power load circuit are powered.

[0077] The coil of the first AC contactor KM1 is connected in series with the normally open point of the first relay KA1 ; the normally open point of the first relay KA1 is electrically connected to the third phase L3 of the three-phase five-wire circuit 1 and the neutral line N1 , respectively.

[0078] In this embodiment, the normally open main contact of the first AC contactor KM1 is connected in series to the energy-saving control circuit, and the normally open point of the first AC contactor KM1 is connected in parallel to the start button.

[0079] In this embodiment, the startup control circuit 2 further includes:

[0080] Emergency stop button;

[0081] The emergency stop button is connected in series between the key switch and the start button.

[0082] By setting an emergency stop button and connecting it in series between the key switch and the start button, when an abnormal situation occurs and the emergency stop button is pressed, the power supply to the entire system can be immediately interrupted, and all running equipment can be quickly stopped, thereby preventing the abnormal event from further expanding and protecting the safety of personnel and equipment.

[0083] In this embodiment, the three-phase five-wire circuit 1 includes: a main switch QF, a first phase L1 , a second phase L2 , a third phase L3 , a neutral line N1 , and a ground line PE.

[0084] The three-phase five-wire circuit 1 is a 380V circuit.

[0085] The main switch is electrically connected to the first phase L1 , the second phase L2 , the third phase L3 and the neutral line N1 .

[0086] The low-power load circuit 4 and the high-power load circuit 5 are respectively connected to the three phases of the three-phase five-wire circuit 1 .

[0087] In this embodiment, the energy-saving and consumption-reducing system further includes:

[0088] Indicator light circuit;

[0089] The indicator light circuit includes: a power indicator light and an operating status indicator light.

[0090] The power indicator light is connected in parallel with the coil of the first AC contactor KM1, and the operation status indicator light is connected in parallel with the coil of the second AC contactor KM2.

[0091] By setting up the indicator light circuit, it can provide intuitive visual feedback to help operators understand the current status of the system.

[0092] For example, the power indicator light is connected in parallel with the coil of the first AC contactor KM1. When the main switch QF is closed and the system is powered, the power indicator light comes on, indicating that the system is in standby or running state, allowing the operator to quickly confirm whether the system has power and avoid operating errors due to power problems;

[0093] Connecting the operating status indicator light in parallel with the coil of the second AC contactor KM2 can show whether the system is in energy-saving mode. When the first button switch is pressed and the coil of the second relay KA2 is energized, it is energy-saving mode. The energy-saving mode indicator light lights up, and the operator can determine that the system has switched to energy-saving mode, thereby reducing unnecessary energy consumption.

[0094] The energy-saving and consumption-reducing system also includes:

[0095] Reset button switch;

[0096] The reset push button switch is connected in parallel with the first push button switch.

[0097] During non-production periods or after an emergency situation is resolved, operators can quickly restore the system to normal operation through the reset button switch, reducing downtime and improving production efficiency. At the same time, the reset button switch increases the flexibility of manual control. Operators can manually restore system operation after confirming safety, ensuring that all safety checks have been completed before resuming production.

[0098] The energy-saving and consumption-reducing system for automated assembly line production equipment of this embodiment supports low-power operation of assembly line production equipment, saving electricity and increasing costs; at the same time, through the first button switch and the reset button switch, it supports manual control, so that in energy-saving mode, that is, when the high-power load circuit is not powered, it can be quickly converted to a high-power load circuit power-on mode, thereby quickly resuming production.
