This invention, by setting a clamping part to fix the PCB board, prevents it from shifting during welding, thus avoiding affecting the welding effect. Simultaneously, a temperature sensor is fixedly installed near the welding torch, and the temperature sensor is electrically connected to a warning light. When the temperature is too high, it will prompt the worker to move the welding torch away from the PCB board, achieving the effect of preventing damage to welding components and weak welding.
[0004] However, although the aforementioned PCB board soldering device has a temperature sensor near the soldering gun to alert workers, it does not have a specific protective mechanism to protect it. If workers do not react in time, there is still a risk of damaging components.
[0005] To address the aforementioned issues, a protective PCB board soldering device is proposed. Utility Model Content

Connecting plates are fixedly installed at both ends of the sliding column.
[0009] The protective mechanism includes storage racks installed at both ends of the top of the processing table, and protective plates are slidably connected to the inner walls of the storage racks.

[0016] Preferably, the cross plate is positioned above the threaded rod to protect it.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] This protective PCB welding device uses an adjustable mechanism and a temperature sensor to monitor the welding torch temperature in real time. Once the temperature exceeds the preset safety value, the controller responds quickly and immediately activates the drive cylinder to drive the processing table to descend rapidly. This temperature sensing and adjustment mechanism ensures that the PCB board can be moved away from the heat source in time when the welding torch is abnormally hot, effectively avoiding problems such as damage to electronic components, circuit deformation, or deterioration of board performance caused by overheating, and greatly improving the safety of the PCB welding process.
[0019] As the processing table descends, the drive motor operates synchronously, causing the protective plate to quickly unfold and close, providing a double reliable protective barrier for the PCB board. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0027] Example
[0028] like Figure 1-3As shown, the system includes a processing base 1, an adjustment mechanism 2 on the top of the processing base 1, a mounting frame 4 at the center of the top of the adjustment mechanism 2, a controller 5 on one side of the mounting frame 4, a welding torch 6 connected to the bottom guide rail of the mounting frame 4, and a temperature sensor 7 located slightly below the center of the welding torch 6. The adjustment mechanism 2 includes a bottom mounting frame 201 slidably connected to the top wall of the processing base 1, a processing table 202 mounted on the top of the bottom mounting frame 201, two sets of inclined grooves 203 on both sides of the bottom mounting frame 201, a sliding column 204 passing through the inclined grooves 203 on both sides of the bottom mounting frame 201 and slidably connected to the inclined grooves 203, and connecting plates 205 fixedly mounted at both ends of the sliding column 204. The adjustment mechanism 2 also includes a drive cylinder 206 mounted at one end of the processing base 1, and limit seats 207 installed around the top of the processing base 1. Connecting parts 208 are slidably connected to the inner wall of the limit seats 207.
[0029] It should be noted that, in this embodiment, during PCB board soldering, the drive cylinder 206 is installed at one end of the processing base 1, the limiting seat 207 is installed around the top of the processing base 1, the connecting piece 208 is slidably connected to the inner wall of the limiting seat 207, and both the connecting plate 205 and the connecting piece 208 are fixedly connected to the processing table 202. At this time, the sliding column 204 is located at the highest point of the inclined groove 203, and the processing table 202 is in a higher position. When the temperature sensor 7 detects that the temperature of the soldering torch 6 exceeds the preset safe temperature value, it transmits a signal to the controller 5. The controller 5... Upon receiving an overheating signal, the control drive cylinder 206 is activated. The output end of the drive cylinder 206 pushes the bottom mounting bracket 201 to slide on the top wall of the processing base 1. At the same time, the sliding column 204 slides downward in the inclined groove 203 until the sliding column 204 slides to the lowest point of the inclined groove 203. At this time, the connecting parts 208 installed around the bottom of the processing table 202 slide in the limit seat 207, and the height of the processing table 202 is reduced, so that the PCB board placed on the processing table 202 is away from the soldering gun 6, avoiding damage to the PCB board due to the overheating of the soldering gun 6.
[0030] like Figure 4 , 5As shown, the protective mechanism 3 includes a storage rack 301 installed at both ends of the top of the processing table 202. A protective plate 302 is slidably connected to the inner wall of the storage rack 301. The protective mechanism 3 also includes a sliding groove 303 opened on both sides of the storage rack 301. A drive motor 304 is installed on the side of the storage rack 301 away from the welding torch 6. An installation block 305 is welded to the middle of the top of the storage rack 301 near the welding torch 6. A horizontal plate 306 is welded between one side of the storage rack 301 and the installation block 305. A movable plate 307 is provided above the protective plate 302. The bottom sides of the movable plate 307 are connected to the sides of the protective plate 302. A rubber layer 308 is glued to the side of the protective plate 302 near the welding torch 6. A threaded rod 309 is passed through the middle of the movable plate 307. One end of the threaded rod 309 is connected to the output end of the drive motor 304 and is located between the storage rack 301 and the installation block 305.
[0031] It should be noted that in this embodiment, when the temperature adjustment mechanism 2 of the welding torch 6 is operating, the controller 5 simultaneously controls the drive motor 304 to start. The output end of the drive motor 304 drives the threaded rod 309 to rotate. Since the threaded rod 309 is inserted through the middle of the movable plate 307, and the bottom sides of the movable plate 307 are connected to the sides of the protective plate 302, and the bottom of the movable plate 307 is inserted through the slide groove 303 and slidably connected to the slide groove 303, when the threaded rod 309 rotates, the movable plate 307 slides along the slide groove 303 towards the PCB board, and drives the protective plate 302 to unfold from the storage rack 301 until the protective plates 302 on both sides of the processing table 202 are close to the rubber layer 308 and tightly adhere to it, thereby protecting the PCB board.
[0032] The mounting block 305 is welded to the middle of the top of the storage rack 301 near the welding gun 6, providing a support point for one end of the threaded rod 309. The horizontal plate 306 is welded between the storage rack 301 and the mounting block 305 and is located above the threaded rod 309. Its main function is to protect the threaded rod 309, prevent some spatter generated by the welding gun 6, and avoid the threaded rod 309 from getting stuck due to foreign objects. (In this device, the transmission structure formed by the drive motor 304 and the threaded rod 309 has a self-locking function. After the protective plate 302 moves into place, it can firmly maintain the current position of the protective plate 302 by relying on the predetermined self-locking mechanism between the drive motor 304 and the threaded rod 309, preventing it from moving accidentally due to external forces or other factors. This self-locking function is widely used in many automated equipment involving screw drives and is a well-known and mature technology in this field. Its detailed implementation will not be described here.)
[0033] Furthermore, during the welding process, the temperature sensor 7 continuously collects the temperature data of the welding torch 6 and transmits this data to the controller 5 in real time. After receiving the temperature data from the temperature sensor 7, the controller 5 compares it with a preset temperature threshold. If the temperature data exceeds the preset temperature threshold, the controller 5 determines that the temperature of the welding torch 6 is too high and sends a control signal to the drive cylinder 206 and the drive motor 304. After receiving the signal, the drive cylinder 206 and the drive motor 304 control the operation of the adjustment mechanism 2 and the protective mechanism 3. (In this device, the temperature sensor 7 monitors the temperature of the welding torch 6 in real time, and the controller 5 processes the collected temperature data according to the preset program and sends corresponding instructions to the drive motor 304 and the drive cylinder 206 according to the predetermined control logic to achieve coordinated control of the protective mechanism 3 and the adjustment mechanism 2. This temperature monitoring and equipment linkage control method has been widely used in the field of related automation equipment and is a well-known existing technology in the field of automation. It will not be described in detail here.)
[0034] Working principle of this utility model:
[0035] Refer to the instruction manual appendix Figure 1-5 During PCB board soldering, the drive cylinder 206 is installed at one end of the processing base 1, and the limiting seat 207 is installed around the top of the processing base 1. The connecting piece 208 is slidably connected to the inner wall of the limiting seat 207. The connecting plate 205 and the connecting piece 208 are both fixedly connected to the processing table 202. At this time, the sliding column 204 is located at the highest point of the inclined groove 203, and the processing table 202 is in a higher position. When the temperature sensor 7 detects that the temperature of the soldering torch 6 exceeds the preset safe temperature value, it transmits a signal to the controller 5. The controller 5 receives the temperature over-temperature signal. After the high signal, the control drive cylinder 206 is started. The output end of the drive cylinder 206 pushes the bottom mounting bracket 201 to slide on the top wall of the processing base 1. At the same time, the slide column 204 slides down in the inclined groove 203 until the slide column 204 slides to the lowest point of the inclined groove 203. At this time, the connectors 208 installed around the bottom of the processing table 202 slide in the limit seat 207, and the height of the processing table 202 is reduced, so that the PCB board placed on the processing table 202 is away from the soldering gun 6, avoiding damage to the PCB board due to the excessive temperature of the soldering gun 6.
[0036] Synchronously, the controller 5 controls the drive motor 304 to start, and the output end of the drive motor 304 drives the threaded rod 309 to rotate. Since the threaded rod 309 passes through the middle of the movable plate 307, and the bottom sides of the movable plate 307 are connected to the sides of the protective plate 302, and the bottom of the movable plate 307 passes through the slide groove 303 and is slidably connected to the slide groove 303, when the threaded rod 309 rotates, the movable plate 307 slides along the slide groove 303 towards the PCB board, and drives the protective plate 302 to unfold from the storage rack 301 until the protective plates 302 on both sides of the processing table 202 are close to the rubber layer 308 and stick tightly, thereby protecting the PCB board.
[0037] When the temperature of the welding torch 6 drops to a safe temperature range, the temperature sensor 7 transmits a signal to the controller 5. The controller 5 controls the drive cylinder 206 to reverse, causing the bottom mounting bracket 201 to lift the processing table 202 and the slide column 204 to return to the highest point of the inclined groove 203. At the same time, the controller 5 controls the drive motor 304 to rotate in the opposite direction, causing the threaded rod 309 to reverse. The movable plate 307 moves along the slide groove 303 to store the protective plate 302 in the storage rack 301, after which the welding operation can continue.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
