[0041] Connecting platform equipment 01, spraying equipment 02, and wave soldering equipment 03;

[0042] Conveying device 1, connecting conveying mechanism 11, spray conveying mechanism 12 and welding conveying mechanism 13, exhaust device 2, heating device 3, control device 4, connecting material detection component 51, spray material detection component 52 and welding material detection component 53. Detailed Implementation

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] This utility model discloses a wave soldering system, as shown in the attached figure. Figure 1As shown, in addition to the conveying device 1, exhaust device 2, heating device 3, and control device 4, the system also includes a transfer platform device 01, a spraying device 02, and a wave soldering device 03. The conveying device 1 is located between the transfer platform device 01, the spraying device 02, and the wave soldering device 03, allowing materials to be transported from the transfer platform device 01 to the wave soldering device 03. The materials mentioned can be circuit boards. The exhaust device 2 is located directly above the spraying device 02 and is used to exhaust air outwards, ensuring a clean working environment. The heating device 3 is located inside the wave soldering device 03 and is used to heat the solder to solder components and circuit boards. The control device 4 is connected to the conveying device 1, the exhaust device 2, and the heating device 3.

[0046] The control device 4 has pre-stored the system's operating modes, which are divided into energy-saving mode and normal mode. Energy-saving mode refers to the operation mode in which all equipment operates at lower power, resulting in lower energy consumption. Normal mode refers to the operation mode in which all equipment operates at normal power, resulting in higher energy consumption.

[0047] When the control device 4 generates an energy-saving switching command, it retrieves the corresponding operating mode and switches to the energy-saving mode, achieving automatic switching and avoiding energy waste caused by delayed switching, thus reducing energy consumption. It should be noted that the energy-saving switching command refers to the command to switch the operating mode to the energy-saving mode. It can be generated by the control device 4 based on trigger signals fed back from sensors, but is not limited to this.

[0048] When the working mode is switched to energy-saving mode, the control device 4 generates a power reduction command and sends the power reduction command to the conveying device 1, the exhaust device 2 and the heating device 3 respectively, so as to reduce the output power of the three devices. This reduces the output power of the conveying device 1, the exhaust device 2 and the heating device 3 in energy-saving mode, reduces energy consumption, avoids energy waste and helps to achieve energy saving and consumption reduction.

[0049] In a preferred embodiment, the conveying device 1 includes a conveying drive component that provides torque to the conveying device 1. The conveying device 1 also includes an exhaust drive component that provides torque to the exhaust device 2. Both the conveying drive component and the exhaust drive component can be servo motors. Both the conveying drive component and the exhaust drive component are connected to the control device 4. When the control device 4 generates a power reduction command, it directly sends the command to both the conveying drive component and the exhaust drive component, reducing their rotational speeds until their actual speeds are reduced to a set speed. This causes the conveying drive component and the exhaust drive component to stop rotating or rotate at low speed, thereby reducing the output power of both the conveying device 1 and the exhaust device 2 to a set power. This ensures that the power consumption of both the conveying device 1 and the exhaust device 2 is minimized in energy-saving mode. This achieves automatic adjustment of the power consumption of both the conveying device 1 and the exhaust device 2, resulting in a high degree of automation, more accurate adjustment results, and more convenient operation.

[0050] In a preferred embodiment, the heating device 3 includes a heater connected to the control device 4. When the control device 4 generates a power reduction command, the actual current of the heater in the control device 4 is reduced to a set current, causing the heating device 3 to perform low-temperature heating, thereby reducing the output power of the heating device 3 to a specified power, and minimizing the power consumption of the heating device 3 in energy-saving mode. This achieves automatic adjustment of the power consumption of the heating device 3, with a high degree of automation, more accurate adjustment, and greater convenience.

[0051] In a first specific embodiment, the wave soldering system further includes a timer connected to the control device 4. The timer records the operating time of the conveyor 1, the exhaust device 2, and the heating device 3. When the timer sends a feedback signal to the control device 4, the control device 4 determines whether the operating time of the conveyor 1, the exhaust device 2, and the heating device 3 is within the set energy-saving time period. If so, it generates an energy-saving switching command to switch to energy-saving mode; otherwise, it generates a normal switching command to switch to normal mode. The set energy-saving time period mentioned in this document refers to the energy-saving time set according to the production plan. This invention uses a set energy-saving time method to automatically switch the entire system to energy-saving mode and automatically switch back to normal mode when the energy-saving mode ends, maximizing energy savings.

[0052] When control device 4 generates a normal switching command, it retrieves the corresponding operating mode and switches to the normal mode, achieving automatic switching. This avoids energy waste caused by delayed switching and reduces energy consumption. It's important to note that the normal switching command refers to the command to switch the operating mode to the normal mode.

[0053] When the working mode is switched to normal mode, the control device 4 generates a power increase command and sends the power increase command to the conveying device 1, the exhaust device 2 and the heating device 3 respectively, so as to increase the output power of the three devices, so that the output power of the conveying device 1, the exhaust device 2 and the heating device 3 in normal mode increases, ensuring that each device can operate normally.

[0054] The wave soldering system also includes a conveyor rotation detection device, an exhaust rotation detection device, and a heating temperature detection device. The conveyor rotation detection device detects the rotational speed of the conveyor drive component of conveyor device 1, and the exhaust rotation detection device detects the rotational speed of the exhaust drive component of exhaust device 2. Both the conveyor rotation detection device and the exhaust rotation detection device can be encoders. The heating temperature detection device detects the heating temperature of the heater in heating device 3, and can specifically be a temperature sensor. The conveyor rotation detection device, the exhaust rotation detection device, the heating temperature detection device, the conveyor drive component, the exhaust drive component, and the heater are all connected to the control device 4.

[0055] When the conveyor rotation detection device detects that the rotational speed of the conveyor drive component is outside the normal set speed range in normal mode, it means that the rotational speed of the conveyor drive component is abnormal. The conveyor rotation detection device sends a signal to the control device 4. After judgment and processing, the control device 4 sends a command to the conveyor drive component to automatically adjust its rotational speed until it is within the normal set speed range, thereby improving the conveying efficiency in normal mode. The normal set speed range mentioned in this text refers to the optimal speed range of the conveyor drive component in normal mode.

[0056] When the exhaust rotation detection device detects that the speed of the exhaust drive component is outside the normal specified speed range in normal mode, it means that the speed of the exhaust drive component is abnormal. The exhaust rotation detection device sends a signal to the control device 4. After judgment and processing, the control device 4 sends a command to the exhaust drive component to automatically adjust its speed until it is within the normal specified speed range, thereby improving the exhaust efficiency in normal mode. The normal specified speed range mentioned in this text refers to the optimal speed range of the exhaust drive component in normal mode.

[0057] When the heating temperature detection device detects that the heating temperature of the heater in normal mode is not within the normal temperature range, it means that the heating device 3 is malfunctioning in normal mode. The heating temperature detection device sends a signal to the control device 4. After judgment and processing, the control device 4 sends a command to the heater to automatically adjust the heater current until the heating temperature is within the normal temperature range, thereby improving the heating efficiency in normal mode. The normal temperature range mentioned in this text refers to the optimal temperature range of the heating device 3 in normal mode.

[0058] The wave soldering system also includes an ambient temperature detection device, an alarm device, and a heat dissipation device, all connected to the control device 4. The ambient temperature detection device, specifically a temperature sensor, detects the temperature of the heating zone of the heating device 3. The alarm device issues an alarm. The heat dissipation device dissipates heat from the heating zone; preferably, it includes a cooling fan and a cooling motor.

[0059] When the ambient temperature detection device detects that the temperature of the heating zone exceeds the maximum set position, the temperature of the heating zone is too high. The ambient temperature detection device sends a feedback signal to the control device 4. After judgment and processing, the control device 4 sends an instruction to the alarm device and the heat dissipation device, which automatically activate the alarm device and the heat dissipation device. The alarm device reminds the operator to pay attention to the temperature of the heating zone, and the heat dissipation device cools down the heating zone as soon as possible.

[0060] In the second specific implementation, the wave soldering system also includes a material detection device and a material shortage timer, both connected to the control device 4. The material detection device is used to detect whether the conveying device 1 is conveying material; the material detection device can be a laser sensor or an obstacle removal device, etc. The material shortage timer is used to record the time during which the conveying device 1 has not conveyed material.

[0061] When the material detection device detects that the conveyor 1 is not conveying material, it sends a feedback signal to the control device 4. The control device 4 then processes the signal and sends a command to the material-free timing device, which automatically starts and records the time during which the conveyor 1 has not conveyed material. The material-free timing device sends the recorded time of no material conveying to the control device 4. When the control device 4 determines whether the time of no material conveying exceeds the set material conveying time, if so, it generates an energy-saving switching command and switches to energy-saving mode; otherwise, it generates a normal switching command and switches to normal mode. In addition to using a set time to switch working modes, this invention also switches working modes by recording the time of no material conveying.

[0062] The conveying device 1 includes a connecting conveyor 11, a spray conveyor 12, and a welding conveyor 13 connected sequentially. The connecting conveyor 11 and the spray conveyor 12 are both horizontally positioned; the welding conveyor 13 is inclined. Materials pass sequentially through the connecting conveyor 11, the spray conveyor 12, and the welding conveyor 13, achieving continuous transmission, eliminating ineffective time, and improving conveying efficiency. The connecting conveyor 11, the spray conveyor 12, and the welding conveyor 13 can all be roller conveyors, but are not limited to these.

[0063] The material detection device includes a connecting material detection element 51, a spray material detection element 52, and a welding material detection element 53, all of which are connected to the control device 4. All three can be laser sensors, but are not limited to these. The connecting material detection element 51 is used to detect whether there is material in the connecting area of ​​the connecting conveyor mechanism 11; the spray material detection element 52 is used to detect whether there is material in the spray area of ​​the spray conveyor mechanism 12; and the welding material detection element 53 is used to detect whether there is material in the working area of ​​the welding conveyor mechanism 13.

[0064] When the control device 4 receives signals from the material receiving detector 51, the spray material detector 52, and the welding material detector 53 simultaneously, it means that none of the three conveying mechanisms are conveying material, and the control device 4 automatically starts the material shortage timer.

[0065] It should be noted that the controller should include a signal receiving unit, a signal judging unit, and a signal transmitting unit. The signal receiving unit is used to receive electrical signals sent by the timing device, the conveyor rotation detection device, the exhaust rotation detection device, or other detection devices such as the conveyor rotation detection device. The signal judging unit is electrically connected to the signal receiving unit so that it can determine whether the signal received by the signal receiving unit is a trigger signal. The signal transmitting unit is electrically connected to the signal judging unit so that it can send the judgment signal generated by the signal judging unit to the actuators such as the conveyor device 1, the exhaust device 2, and the heating device 3. The specific arrangement of the signal receiving unit, the signal judging unit, and the signal transmitting unit can refer to the prior art; in this utility model, only the application scenario of the above three components has been changed, and no substantial improvement has been made. Obviously, controllers with this structure are widely used in existing automatic control equipment, such as MCUs, DSPs, or single-chip microcomputers. The key point of this utility model is that the controller combines each detection device and each actuator in a pairwise correspondence.

[0066] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0067] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
