In existing solutions, the nitrogen system of selective wave soldering will maintain a large gas flow value under welding conditions to ensure a large gas consumption to meet welding requirements, and will also maintain a large gas consumption under non-welding conditions, which leads to a waste of resources. In order to solve the above problems, the present application provides an energy-saving system and a control system, which maintains a small gas flow value under energy-saving conditions through an energy-saving module to provide a small gas consumption, avoid waste of resources, and save costs.

Obviously, the described embodiments are only 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 should fall within the scope of protection of the present invention.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0036] The following describes an energy-saving system and control system of the present application. Figure 1 , an energy-saving system of the present application in one embodiment comprises: a control module 4, a gas source 1, an energy-saving module 2 and a gas ring outlet 3;

[0037] One end of the energy-saving module 2 is connected to the gas source 1, and the other end of the energy-saving module 2 is connected to the gas ring outlet 3. The gas in the gas source 1 flows to the gas ring outlet 3 through the energy-saving module 2;

[0038] The control module 4 is connected to the energy-saving module 2, and is used to obtain the real-time flow value of the gas flowing through the energy-saving module 2 from the energy-saving module 2 under energy-saving conditions, and control the energy-saving module 2 according to the real-time flow value to adjust the real-time flow value to a preset energy-saving flow value.

[0039] The working principle of this embodiment is as follows:

[0040] Under welding conditions, after receiving the welding instruction, the control module 4 actively collects the real-time flow value of the gas flowing through the energy-saving module 2 from the energy-saving module 2, and parses the welding instruction to obtain the welding flow value, wherein the welding flow value refers to the flow value that can complete the welding work. The control module 4 compares the real-time flow value with the welding flow value, and if the real-time flow value is not equal to the welding flow value, the energy-saving module 2 is controlled to adjust the real-time flow value to the welding flow value.

[0041] Under the energy-saving condition, after receiving the energy-saving instruction, the control module 4 actively collects the real-time flow value of the gas flowing through the energy-saving module 2 from the energy-saving module 2, and analyzes the energy-saving instruction to obtain the energy-saving flow value, wherein the energy-saving flow value refers to the gas flow value that can keep the tin nozzle used for welding from being oxidized in the non-welding state. The control module 4 compares the real-time flow value with the energy-saving flow value. If the real-time flow value is not equal to the energy-saving flow value, the energy-saving module 2 is controlled to adjust the real-time flow value to the energy-saving flow value. Among them, the energy-saving flow value is less than the welding flow value.

[0042] In the embodiment of the present application, under energy-saving working conditions, the energy-saving module 2 can monitor the real-time flow value of the gas flowing through the energy-saving module 2 and send it to the control module 4. The control module 4 compares the real-time flow value with the energy-saving flow value, and after confirming that there is a difference between the two, it will control the energy-saving module 2 so that the real-time flow value is close to the energy-saving flow value. In this way, in the non-welding state, that is, under energy-saving working conditions, the system does not need to maintain a fixed large gas flow at all times, but only needs to maintain the real-time flow value near a smaller energy-saving flow value, so as to avoid excessive gas from going out of the gas ring outlet 3, avoid waste of resources, save energy and reduce emissions, and save costs for users.

[0043] See also Figure 2 , another embodiment of an energy-saving system of the present application comprises: a control module 4, a gas source 1, an energy-saving module 2, a gas ring outlet 3, a manual sliding valve 5, a pneumatic triplet 6 and a pressure gauge 7;

[0044] One end of the energy-saving module 2 is connected to the gas source 1, and the other end of the energy-saving module 2 is connected to the gas ring outlet 3. The gas in the gas source 1 flows to the gas ring outlet 3 through the energy-saving module 2;

[0045] The control module 4 is connected to the energy-saving module 2, and is used to obtain the real-time flow value of the gas flowing through the energy-saving module 2 from the energy-saving module 2 under energy-saving conditions, and control the energy-saving module 2 according to the real-time flow value to adjust the real-time flow value to a preset energy-saving flow value.

[0046] Specifically, the manual sliding valve 5 is connected between the gas source 1 and the energy-saving module 2 to control the on-off of the gas path from the gas source 1 to the gas ring outlet 3 .

[0047] The pneumatic triplet 6 is connected between the manual sliding valve 5 and the energy-saving module 2, and is used to dry and filter the gas. Specifically, the pneumatic triplet 6 includes: a first filter 61, a gas valve 62 and a second filter 63;

[0048] The first filter 61, the gas valve 62 and the second filter 63 are connected in series in sequence. The first filter 61 is connected to the gas source 1, and the second filter 63 is connected to the energy-saving module 2. The first filter 61 and the second filter 63 are used to filter the gas, and the gas valve 62 is used to control the on-off of the gas circuit.

[0049] The pressure gauge 7 is connected between the second filter 63 and the energy-saving module 2 , and is used to detect the pressure of the gas and upload it to the control module 4 .

[0050] The energy-saving module 2 includes: a first electronic flow meter 21, a second electronic flow meter 22, a first valve 23 and a second valve 24;

[0051] The first electronic flowmeter 21 and the first valve 23 are connected in series to form a first branch, the second electronic flowmeter 22 and the second valve 24 are connected in series to form a second branch, the first branch and the second branch are connected in parallel to form a parallel branch, one end of the parallel branch is connected to the gas source 1, and the other end of the parallel branch is connected to the gas ring outlet 3. Specifically, the first valve 23 is connected to the pressure gauge 7, the second valve 24 is connected to the pressure gauge 7, and the first electronic flowmeter 21 and the second electronic flowmeter 22 are connected to the gas ring outlet 3.

[0052] The first electronic flow meter 21 is used to send the real-time flow value to the control module 4 when the control module 4 controls the first valve 23 to open and the second valve 24 to close under the welding condition, so that the control module 4 controls the valve of the first electronic flow meter 21 according to the real-time flow value, thereby adjusting the real-time flow value to a preset welding flow value;

[0053] The second electronic flow meter 22 is used to send the real-time flow value to the control module 4 when the control module 4 controls the second valve 24 to open and the first valve 23 to close under energy-saving conditions, so that the control module 4 controls the valve of the second electronic flow meter 22 according to the real-time flow value, thereby adjusting the real-time flow value to the energy-saving flow value.

[0054] The first valve 23 is a one-way valve, and the second valve 24 is a one-way valve.

[0055] The working principle of this embodiment is as follows:

[0056] Under welding conditions, after receiving the welding instruction, the control module 4 opens the first valve 23 and closes the second valve 24. At this time, the first branch is flowing and the second branch is closed. The control module 4 actively collects the real-time flow value flowing through the first electronic flow meter 21 from the first electronic flow meter 21, and analyzes the welding instruction to obtain the welding flow value, wherein the welding flow value refers to the flow value that can complete the welding work, generally 20-35L / min. The control module 4 compares the real-time flow value with the welding flow value. If the real-time flow value is not equal to the welding flow value, the valve of the first electronic flow meter 21 is controlled to adjust the real-time flow value to the welding flow value.

[0057] Under the energy-saving condition, after receiving the energy-saving instruction, the control module 4 opens the second valve 24 and closes the first valve 23. At this time, the second branch is flowing and the first branch is closed. The control module 4 actively collects the real-time flow value of the gas flowing through the second electronic flow meter 22 from the second electronic flow meter 22, and analyzes the energy-saving instruction to obtain the energy-saving flow value therein, wherein the energy-saving flow value refers to the gas flow value that can keep the tin nozzle used for welding from being oxidized in a non-welding state, which is generally 5-8L / min. The control module 4 compares the real-time flow value with the energy-saving flow value. If the real-time flow value is not equal to the energy-saving flow value, the valve of the second electronic flow meter 22 is controlled to adjust the real-time flow value to the energy-saving flow value. Among them, the energy-saving flow value is less than the welding flow value.

[0058] For example, the preset welding flow value is 20L / min, and the energy-saving flow value is 5L / min. Under welding conditions, the control module 4 opens the first valve 23 and closes the second valve 24. The real-time flow value flowing through the first electronic flow meter 21 is 18L / min. Since 18<20, it is necessary to adjust the valve of the first electronic flow meter 21 and open the valve to make the real-time flow value reach 20L / min; under energy-saving conditions (such as equipment maintenance, equipment standby reaching energy-saving time, welding module in and out of the board, production line midway rest, change of machine model, etc.), the control module 4 opens the second valve 24 and closes the first valve 23. The real-time flow value flowing through the second electronic flow meter 22 is 6L / min, then it is necessary to adjust the valve of the second electronic flow meter 22 and close the valve to make the real-time flow value drop to 5L / min.

[0059] In this embodiment, by selecting the corresponding branch under different working conditions and adjusting the real-time flow value, the real-time flow value can reach the welding flow value under welding conditions and the energy-saving flow value under energy-saving conditions. The real-time flow value can be controlled, that is, the gas consumption is reasonably controlled, thereby improving work efficiency.

[0060] See also Figure 3, another embodiment of an energy-saving system of the present application comprises: a control module 4, a gas source 1, an energy-saving module 2, a gas ring outlet 3, a manual sliding valve 5, a pneumatic triplet 6 and a pressure gauge 7;

[0061] Part of the content of this embodiment Figure 2 The corresponding embodiments are similar and will not be described here in detail, but the difference lies in the energy-saving module 2. The energy-saving module 2 of this embodiment includes: a third electronic flow meter 25 and a flow proportional valve 26;

[0062] One end of the flow proportional valve 26 is connected to the gas source 1, and the other end of the flow proportional valve 26 is connected to the gas ring outlet 3 via the third electronic flow meter 25;

[0063] The third electronic flow meter 25 is used to send the real-time flow value to the control module 4 under energy-saving conditions, so that the control module 4 controls the flow proportional valve 26 according to the real-time flow value, thereby adjusting the real-time flow value to the energy-saving flow value, or, to send the real-time flow value to the control module 4 under welding conditions, so that the control module 4 controls the flow proportional valve 26 according to the real-time flow value, thereby adjusting the real-time flow value to the preset welding flow value.

[0064] The working principle of this embodiment is as follows:

[0065] Under welding conditions, after receiving the welding instruction, the control module 4 actively collects the real-time flow value flowing through the third electronic flow meter 25 from the third electronic flow meter 25, and analyzes the welding instruction to obtain the welding flow value, wherein the welding flow value refers to the flow value that can complete the welding work, generally 20-35L / min. The control module 4 compares the real-time flow value with the welding flow value. If the real-time flow value is not equal to the welding flow value, the flow proportional valve 26 is controlled to adjust the real-time flow value to the welding flow value.

[0066] Under the energy-saving condition, after receiving the energy-saving instruction, the control module 4 actively collects the real-time flow value of the gas flowing through the third electronic flow meter 25 from the third electronic flow meter 25, and analyzes the energy-saving instruction to obtain the energy-saving flow value, wherein the energy-saving flow value refers to the gas flow value that can keep the tin nozzle used for welding from being oxidized in the non-welding state, which is generally 5-8L / min. The control module 4 compares the real-time flow value with the energy-saving flow value. If the real-time flow value is not equal to the energy-saving flow value, the flow proportional valve 26 is controlled to adjust the real-time flow value to the energy-saving flow value. Among them, the energy-saving flow value is less than the welding flow value.

[0067] For example, the preset welding flow value is 20L / min, and the energy-saving flow value is 5L / min. Under welding conditions, the control module 4 collects the real-time flow value flowing through the third electronic flow meter 25 as 18L / min. Since 18<20, it is necessary to adjust the flow proportional valve 26 and open the valve to make the real-time flow value reach 20L / min; under energy-saving conditions (such as equipment maintenance, equipment standby reaching energy-saving time, welding module in and out of the board, production line midway rest, change of machine model, etc.), the control module 4 collects the real-time flow value flowing through the third electronic flow meter 25 as 6L / min, then it is necessary to adjust the flow proportional valve 26 and close the valve to make the real-time flow value drop to 5L / min.

[0068] In this embodiment, the real-time flow value is monitored by the third electronic flow meter 25, and the real-time flow value is adjusted according to the flow proportional valve 26, so that it reaches the welding flow value under the welding condition and reaches the energy-saving flow value under the energy-saving condition. When welding, it is set to the welding flow value, and a larger flow value can meet the welding requirements. When energy saving, it is set to the energy-saving flow value, and a smaller flow value can achieve the purpose of energy saving and emission reduction, thereby improving work efficiency.
