Description

Technical Field

[0001] This application relates to the field of hot air gun technology, and in particular to a multi-station hot air gun. Background Technology

[0002] In the research and development and production of electronic products, especially during the debugging and small-batch trial production stages of circuit boards (PCBs), technicians often need to repeatedly replace and debug components on the PCBs. At this time, hot air soldering stations and their core component—the hot air gun—become key tools for improving the efficiency of this operation. The hot air gun rapidly heats the airflow to a temperature high enough to melt solder through internal heating elements, forming a concentrated stream of high-temperature hot air. During operation, technicians simply hold or hold the hot air gun, aiming its nozzle at the area of ​​the multi-pin device to be disassembled. The high-temperature hot air simultaneously and evenly heats the solder joints of all pins of the device, causing the solder to melt collectively in a short time. This process eliminates the need to operate on each pin individually, allowing for the non-destructive desoldering of the entire device in one go, thus greatly improving the efficiency of disassembling multi-pin components and significantly simplifying the debugging process.

[0003] In the existing technology, the utility model patent with publication number CN220507267U discloses a hot air gun with a single-station design, which cannot simultaneously meet the needs of multiple people collaborating or multi-tasking in parallel. In actual production, debugging, or repair workshop environments, when multiple technicians need to disassemble components on different circuit boards simultaneously, or when a single technician needs to alternately disassemble multiple components in different areas while handling a complex circuit board, the single-station hot air gun becomes a significant efficiency bottleneck. Technicians must queue to use the single equipment resource, resulting in wasted working time and idle personnel. Even for single-person operation, after disassembling one component, if another component on the same board needs to be processed immediately, it is necessary to wait for the hot air gun to cool down, reset, or readjust parameters, making seamless multi-tasking impossible. This inherent limitation of "only one operation point can be served at a time" severely restricts the improvement of overall work efficiency and is difficult to adapt to the requirements of high concurrency and rapid turnaround in modern electronic manufacturing and repair processes. Utility Model Content

[0004] To address the issue of single-station hot air guns limiting overall work efficiency, this application provides a multi-station hot air gun.

[0005] The multi-station hot air gun provided in this application adopts the following technical solution:

[0006] A multi-station hot air gun, comprising:

[0007] The host is equipped with multiple fans and has multiple air outlets, each of which is connected to the air outlet of a fan.

[0008] Multiple hot air gun bodies, with the air inlet of each hot air gun body connected to the air outlet, and the host is configured to independently control each of the fans and the corresponding hot air gun bodies to blow out hot air.

[0009] By adopting the above technical solution, multiple hot air output channels are constructed. Through the independent control of each fan and corresponding hot air gun body by the host, independent operation of each hot air output is realized. This allows a single host to support the independent operation of multiple hot air gun bodies at the same time, thereby allowing multiple technicians to operate in parallel or a single technician to efficiently perform multi-task processing. This significantly improves the work efficiency when handling multiple devices or multiple circuit boards in electronic R&D, production debugging and maintenance, and eliminates the queuing and operation interruption problems caused by the uniqueness of equipment resources.

[0010] Optionally, it also includes a hot air gun holder, which has multiple hot air gun storage slots corresponding to the multiple hot air gun bodies.

[0011] By adopting the above technical solution, each hot air gun is equipped with a storage location, realizing the orderly return and rapid positioning management of idle equipment in multi-station operations. This avoids the risks of confusion, mutual interference, or accidental burns caused by the random placement of hot air guns when multiple technicians are working at the same time, and indirectly improves the efficiency of multi-person collaboration and operational safety.

[0012] Optionally, the air gun holder includes a base, on which a plurality of support seats are rotatably connected. Each support seat is provided with an air gun storage position and is configured to be positioned at an angle after rotation.

[0013] By adopting the above technical solution, the rotating connection structure enables each hot air gun body to have independent angle adjustability in the storage position, allowing operators to flexibly adjust the orientation of each hot air gun body according to the workbench layout or personal operating habits, optimize the picking and placing path and reduce spatial interference between multiple operators. At the same time, the positioning design ensures the stability of the storage posture after adjustment, and improves the convenience and spatial adaptability of multi-station collaborative operation.

[0014] Optionally, the top of the support base is provided with an upward-facing slot, and the hot air gun body is connected to a handle anti-scalding sleeve. The handle anti-scalding sleeve is spaced apart from the outer side wall of the hot air gun body, and the handle anti-scalding sleeve can be inserted into the slot.

[0015] By adopting the above technical solution, the slot and the spaced-out anti-scalding sleeve of the handle form a suspended storage structure. The gap between the slot and the hot air gun body forms a heat insulation layer, which not only ensures that the high-temperature gun body is suspended to avoid scalding the support seat, but also significantly improves the anti-tipping stability in the storage state, and facilitates quick blind operation with one hand to pick up and put away the gun.

[0016] Optionally, the base is provided with heat dissipation holes at a position corresponding to the air outlet end of the hot air gun body.

[0017] By adopting the above technical solution, the heat dissipation holes accelerate the dissipation of heat accumulated at the air outlet of the hot air gun, effectively blocking the continuous conduction of high temperature to the base, and preventing the hot air gun base from deforming or aging due to long-term heat exposure.

[0018] Optionally, the hot air gun body is equipped with a gyroscope sensor, and the host is connected to the gyroscope sensor to receive the attitude data of the hot air gun body measured by the gyroscope sensor in real time, and output a control signal to the hot air gun body according to the attitude data of the hot air gun body.

[0019] By adopting the above technical solution, the linkage control mechanism between the gyroscope sensor and the host establishes an adaptive mapping relationship between the device's attitude and operating status. By analyzing the spatial motion data of the hot air gun body in real time, the host dynamically outputs control signals to realize the autonomous switching of the working mode. This essentially solves the operational redundancy of frequent manual start-stop in multi-device systems, endows the hot air gun body with intelligent response capabilities based on changes in physical state, and optimizes the human-machine interaction logic.

[0020] Optionally, when the host receives the attitude data of the hot air gun body and finds it to be in a static state, it outputs a sleep signal to the hot air gun body and the fan; when the host receives the attitude data of the hot air gun body and finds it to be in a non-static state, it outputs a start signal to the hot air gun body and the fan.

[0021] By adopting the above technical solution, the hot air gun automatically enters sleep mode and cuts off the power supply when the hot air gun body is stored at rest, which significantly reduces the standby power consumption of the multi-station system and extends the life of the components; when the gun body is picked up, it instantly wakes up to output hot air, eliminating the operation delay of traditional manual start and stop, realizing a seamless workflow of ready-to-use, especially suitable for scenarios where multiple people frequently alternate operations.

[0022] Optionally, it may also include multiple air nozzles, which are detachably connected to the air outlet end of the hot air gun body;

[0023] The main unit is connected to a nozzle holder on its side, and the nozzle holder has multiple nozzle storage slots.

[0024] By adopting the above technical solutions, the modular separation design of the nozzle and the hot air gun, as well as the multi-storage layout of the nozzle holder, enables centralized classification management and rapid on-demand use of nozzles of various specifications, avoiding the chaos of searching when frequently changing nozzles in multi-workstation operations; at the same time, the nozzle storage space fixes the spatial position of each nozzle, preventing the risk of burns caused by random placement of high-temperature nozzles or mutual adhesion, significantly improving the efficiency of tool switching and operational safety in multi-tasking scenarios.

[0025] Optionally, the nozzle is plugged into the air outlet of the hot air gun body, and the outer wall of the nozzle is provided with a snap-fit ​​part;

[0026] The multi-station hot air gun also includes a plug-in socket, which can interfere with the snap-fit ​​portion to insert the nozzle into or remove it from the hot air gun body.

[0027] By adopting the above technical solution, the interference structure of the plug-in socket and the nozzle locking part forms a touchless lever auxiliary mechanism. The blocking part limits the insertion and the inclined surface guides the insertion and removal with one hand. During installation, the locking part is pressed down and slides into the slot along the inclined surface. Then, force is applied to lock it in place. The opposite force is applied to disassemble it. This completely avoids the risk of burns from operating the high-temperature nozzle by hand, while ensuring the mechanical reliability and airtightness of the connection when replacing multiple sizes of nozzles at high frequency.

[0028] Optionally, the air inlet of the hot air gun body and the air outlet are connected by an electrical male-female connector.

[0029] By adopting the above technical solution, operators can complete the connection or disassembly of the hot air gun body in seconds without tools. It supports the dynamic allocation of the number of workstations according to task requirements. At the same time, the air circuit and circuit are connected / cut off simultaneously during the plugging and unplugging process, realizing the modular hot-swappable hot air gun body and host, enabling the multi-workstation system to have the ability to expand and replace equipment in real time.

[0030] Optionally, the air outlet of the hot air gun body includes a detachably connected air duct and a heating element assembly.

[0031] By adopting the above technical solution, it is possible to replace the heating element component individually without disassembling the entire hot air gun body, and heating element components with different power can be selected.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. By setting up multiple independently controlled fans and corresponding air outlets within the main unit, and connecting them one by one to multiple hot air gun bodies, multiple independent hot air output paths are constructed. The main unit's ability to independently control each air source and corresponding hot air gun body allows a single main unit to support the independent operation of multiple hot air gun bodies simultaneously, completely solving the queuing and operation interruption problems caused by traditional single-station equipment, and significantly improving work efficiency when multiple people collaborate or a single person handles multiple tasks.

[0034] 2. The hot air gun body with integrated gyroscope sensor is linked with the host, and realizes intelligent switching of the device's working status (static sleep / moving start) through real-time attitude perception. This eliminates the redundancy and energy waste of frequent manual start and stop operations, and realizes "ready to use". It is especially optimized for the smoothness of frequent alternation of multiple people.

[0035] 3. With the help of the hot air gun holder (with adjustable angle support and heat dissipation holes) and the nozzle holder, a stable, orderly and heat-dissipating dedicated storage space is provided for each hot air gun body and various nozzle sizes. This effectively avoids the risks of chaotic access, mutual interference, high temperature burns or heat damage caused by random placement of equipment, and greatly improves the operational safety and equipment management efficiency in multi-person and multi-task scenarios.

[0036] 4. The nozzle and the hot air gun body are connected by a plug-in connector and equipped with a plug-in socket, forming a lever-assisted, contactless quick-change mechanism. This allows workers to install and remove high-temperature nozzles with one hand, effortlessly and safely, completely avoiding the risk of burns from bare-hand operation. It also ensures the airtightness and mechanical strength of the connection, greatly improving the efficiency and safety of frequent nozzle changes in multi-tasking scenarios. The multi-storage design of the nozzle holder ensures clear classification and quick location and use of nozzles of different sizes. Attached Figure Description

[0048] The following will be combined with the appendix Figure 1-5 The technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0049] This application discloses a multi-station hot air gun. (Refer to...) Figure 1 The multi-station hot air gun includes a main unit 1, multiple hot air gun bodies 2, a hot air gun base 3, multiple air nozzles 4, and a plug-in socket 5.

[0050] The main unit 1 is equipped with multiple fans (not shown in the figure) and multiple air outlets 11, which are connected to the air outlets of the fans. The air inlet of the hot air gun body 2 is connected to the air outlet 11, and the air outlet of the hot air gun body 2 is detachably connected to the nozzle 4. The main unit 1 is configured to independently control each fan and the corresponding hot air gun body 2 to blow out hot air.

[0051] The main unit 1 is equipped with a control panel, which has buttons for first speed, second speed, third speed, heating up, cooling down, fan speed acceleration, fan speed deceleration, and power. The control panel independently controls the start, stop, airflow, and temperature of each fan and the corresponding hot air gun body 2, enabling independent control of the hot air output of each workstation. This is existing technology and will not be described in detail.

[0052] A nozzle holder 12 is connected to the side of the main unit 1. The nozzle holder 12 has multiple holes forming nozzle storage positions. The nozzle holder 12 can accommodate various sizes of nozzles 4 on the hot air gun body 2, such as four sizes of nozzles 4 with outlet diameters of 6mm, 8mm, 10mm, and 12mm. In an optional embodiment, the diameter of the holes on the nozzle holder 12 is configured to match the outlet diameter of different sizes of nozzles 4. The nozzle holder 12 centrally manages multiple sizes of nozzles 4, avoiding confusion when searching and preventing them from sticking together after being heated.

[0053] The number of hot air gun bodies 2 can be set according to actual needs, such as three or four. In this embodiment, there are two hot air gun bodies 2. Correspondingly, the host 1 is equipped with two fans and two independent air outlets 11. The host 1 can connect to two hot air gun bodies 2 at the same time, supporting independent operation at dual stations. The air inlet and air outlet 11 of the hot air gun body 2 are connected by a plug-in electrical male and female connector. For example, a 12-pin integrated electrical male and female connector can be used to achieve quick connection between the host 1 and the hot air gun body 2.

[0054] The air gun holder 3 is located on the side of the main unit 1. The air gun holder 3 has multiple air gun storage slots corresponding to multiple hot air gun bodies 2. The hot air gun bodies 2 can be stored on the air gun holder 3 when not in use.

[0055] Reference Figure 2 The air gun holder 3 includes a base 31, on which a plurality of bearing seats 32 are rotatably connected. The number of bearing seats 32 is the same as the number of air gun bodies 2. Each bearing seat 32 is provided with an air gun storage position and is configured to be positioned at an angle after rotation.

[0056] Specifically, the base 31 is a U-shaped seat with two opposing clamping plates 31a. The support seat 32 is located between the two clamping plates 31a and is an arc-shaped plate. At two opposing positions of the support seat 32 and the two clamping plates 31a, one position is rotatably connected to the clamping plate 31a via a rotating shaft 33, and the other position is connected to the other clamping plate 31a. Both positions have through holes. The through holes of the support seat 32 have internal threads that connect to the adjusting bolts 34. The support seat 32 and the clamping plates 31a are fastened together by the adjusting bolts 34. Loosening the adjusting bolts 34 adjusts the angle of the support seat 32, and tightening them positions the support seat 32. The adjustable angle of the support seat 32 allows the operator to flexibly adjust the orientation of each hot air gun body 2 according to the workbench layout or personal operating habits, optimizing the pick-up and drop path and reducing spatial interference between multiple operators.

[0057] Reference Figure 3 and Figure 4 The top of the support base 32 is provided with an upward-facing slot 32a. The hot air gun body 2 is connected to a handle anti-scalding sleeve 21. The handle anti-scalding sleeve 21 is spaced apart from the outer wall of the hot air gun body 2. The handle anti-scalding sleeve 21 can be inserted into the slot 32a. The hot air gun body 2 is located inside the support base 32, which enables hanging and storage, avoids scalding the base 31 and improves anti-tipping performance.

[0058] Since the hot air gun holder 3 houses multiple hot air gun bodies 2, the hot air gun bodies 2 will accumulate heat at the air outlet after use. The base 31 is provided with multiple heat dissipation holes 31b at the positions corresponding to the air outlet of the hot air gun bodies 2, so as to facilitate heat dissipation at the air outlet of the hot air gun bodies 2, block high temperature conduction, and prevent the base 31 from deforming and aging.

[0059] The nozzle 4 is plugged into and detached from the air outlet of the hot air gun body 2. The outer wall of the nozzle 4 has a locking portion 41, which in this embodiment is annular. A plug-in / plug seat 5 is provided on the base 31. The plug-in / plug seat 5 can interfere with the locking portion 41 to insert or remove the nozzle 4 from the hot air gun body 2. The plug-in / plug seat 5 and the locking portion 41 form a contactless lever mechanism, avoiding the risk of burns from manual operation.

[0060] Reference Figure 5The plug-in socket 5 includes a U-shaped seat body 51. The upper side wall of the seat body 51 is arc-shaped to fit against the outer side wall of the hot air gun body 2, and has an arc-shaped slot 52 that matches the snap-fit ​​part 41. Both upper ends of the seat body 51 protrude upward to form a stop part 53, and the upper side of the seat body 51 slopes downward from the outside to the inside to form an inclined surface 54.

[0061] When the operator needs to install the nozzle 4, insert the nozzle 4 into the air outlet of the hot air gun body 2, then press the locking part 41 of the nozzle 4 against the blocking part 53, and then slide the nozzle 4 down the inclined surface 54 so that the locking part 41 is inserted into the slot 52 of the plug-in seat 5. Apply force in the direction away from the hot air gun body 2 to make the nozzle 4 more securely installed on the hot air gun body 2. When the operator needs to replace the nozzle 4, follow the same operation, insert the locking part 41 into the slot 52 of the plug-in seat 5, apply force in the direction away from the nozzle 4, and pull the nozzle 4 off the hot air gun body 2.

[0062] The structure of the hot air gun body 2 is existing technology. Based on this, in an optional embodiment, a gyroscope sensor is configured on the circuit board inside the hot air gun body 2. The host 1 is connected to the gyroscope sensor to receive the attitude data of the hot air gun body 2 measured by the gyroscope sensor in real time, and outputs control signals to the hot air gun body 2 according to the attitude data of the hot air gun body 2.

[0063] Specifically, when the host 1 receives attitude data from the hot air gun body 2 indicating a stationary state (e.g., the hot air gun body 2 is placed on the support 32 or on a table), and the gyroscope sensor detects no angle change, the default bit is reset to zero, and a signal is sent back to the host 1. The host 1 then outputs a sleep signal to the hot air gun body 2 and the fan, reducing energy consumption and extending the lifespan of the hot air gun body 2. When the host 1 receives attitude data from the hot air gun body 2 indicating a non-stationary state (i.e., when the operator picks up the hot air gun body), the host 1 outputs a start signal to the hot air gun body 2 and the fan. This allows the operator to directly align the nozzle 4 with the pins of the device to be heated, using high-temperature hot air to heat the solder on the pins. This simplifies the operation process, improves ease of use, and solves the operational redundancy of frequent manual start-stop operations in multi-device systems.

[0064] Multiple fans within the main unit 1 independently supply air to each air outlet 11, which is then delivered to the corresponding hot air gun body 2 for heating output via pluggable electrical male and female connectors. The hot air gun body 2 senses its attitude via a gyroscope: when stationary, the main unit 1 controls sleep mode for energy saving; when picked up, it instantly starts. When idle, the hot air gun body 2 is inserted into the slot 32a of the hot air gun holder 3 for hanging and storage, with the heat dissipation holes 31b accelerating the dissipation of residual heat; the nozzle 4 is stored in the nozzle holder 12, and can be safely removed and installed via the pluggable connector 5 when replacement is needed. The angle of each support 32 is adjustable to adapt to multi-workstation layouts. The main unit 1 panel enables independent control of parameters for each workstation, ultimately achieving the core goal of multi-task parallel processing and efficient resource utilization.

[0065] Furthermore, in an optional embodiment, the hot air gun body 2 includes a connection interface for connecting to the host, a gun housing, a gun circuit board, an air duct extending a certain working distance for conducting hot air, and a heating element assembly (the above is the existing structure). Based on the existing structure, the heating element assembly is detachably connected to the air duct and the nozzle 4, supporting the individual replacement of the heating element assembly without disassembling the entire hot air gun. The heating element assembly uses a gold-plated male and female pin connector for quick replacement and can be configured with heating element assemblies of different power, such as 1000W, 1200W, 1400W, and 1600W, allowing users to select a suitable product according to their power requirements.
