It also undertakes important tasks such as transmitting power and signals. In practical applications, in order to reliably achieve electrical connection, ensure the transmission performance of power and signals, and comprehensively guarantee safety during use, it is necessary to use wiring terminals to connect and use transformers. Through its specific structure and material, the wiring terminals can stably connect the transformer and computer equipment, accurately transmit the power and signals output by the transformer to various components of the computer, and play the role of insulation and fixation during the connection process, effectively preventing the occurrence of electrical accidents.

[0014] The present invention also provides a transformer terminal flip welding method, comprising the following steps:

[0015] S1. Fix the workpiece, i.e., the terminal, on the U-shaped base by operating the blocking clamping device;

[0016] S2. The terminal block is flipped to a suitable angle by operating the speed reduction precision rotation structure, and the wire is placed on the welding part of the terminal block;

[0017] S3. At this time, the terminal block is connected to the wire at a specified angle, and the worker can complete the welding operation of the terminal block and the wire by using a welding gun;

[0018] S4. When the wiring terminal is flipped, it slides on the auxiliary rotating ring through the top and bottom of the T-shaped rotating block to limit the rotation of the driven rotating shaft to prevent the wiring terminal on the driven rotating shaft from shaking when it is flipped.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) Since the rotation speed of the first large tooth can be further reduced, it can drive the active shaft to rotate slowly, thereby reducing the rotation speed of the active shaft, so that the workpiece (terminal) clamped on the active shaft can be slowly flipped to adjust the welding angle and position between the workpiece and the wire, thereby avoiding the poor accuracy of flipping the terminal, which causes it to be unable to stop at the appropriate required welding position angle for use, thereby improving the welding accuracy of the device for the terminal and the wire, thereby improving the welding effect of the device; and the above gear ratio has the opportunity to achieve a degree where the driving disc rotates one circle to drive the active shaft to rotate 1° after a specific match. The specific rotation angle is determined by different gear ratios. By using gears with different numbers of teeth and sizes to control how many degrees the driving disc drives the active shaft to rotate when it rotates one circle, and when the angle of the terminal is greatly adjusted or when it is turned around, it can be achieved by rotating the terminal itself, thereby reducing the limitations of the device during use and improving the use effect of the device;

[0021] (2) The two U-shaped clamps move relative to each other, so that the U-shaped clamps can be clamped and set, so that the top, bottom and side of the U-shaped clamps are in contact with the top, bottom and side of the workpiece, thereby avoiding the shaking of the workpiece during the welding process with the wire, and improving the welding effect of the device on the terminal block; at the same time, the friction between the U-shaped clamps and the workpiece is increased by the rubber patch, avoiding the dislocation or shaking of the workpiece after being clamped, and improving the use effect of the device; at the same time, when the U-shaped clamps are in contact with the workpiece, the blocking cross plate continues to move, so that it moves within the upper limit of the blocking slide column, so that the blocking spring is in a buffering state, thereby enhancing the fixing effect of the workpiece, until the blocking cross plate and the contact pieces on the opposite side of the U-shaped clamps are in contact, indicating that the clamping operation of the workpiece has been completed. If the workpiece is dislocated during use, the two contact pieces will be disconnected, and the control panel will receive the signal in time and use it to notify the operator, so that the staff can be notified in time to deal with the dislocated workpiece, thereby avoiding safety accidents and further reducing the limitations of the device during use;

[0022] (3) When the pressure square plate moves away from the guide base, the air inlet valve is closed and the air outlet valve is opened, so that the gas in the pressure box enters the air inlet hose through the air outlet valve and continuously flows into the gas distribution pipe; when the pressure square plate is reset, the air inlet valve is opened and the air outlet valve is closed, so that the outside gas re-enters the pressure box and waits for the next movement of the pressure square plate, so that the pressure box continuously produces gas and acts on the gas distribution pipe, so that the gas continuously flowing into the gas distribution pipe is ejected through the pressure nozzle, so as to remove the impurities generated when the terminal and the wire are welded. Cleaning can be carried out, and at the same time, harmful gases generated during welding can be prevented from being pushed to the welding site and affecting the welding operation of the workers, thereby ensuring the health of the workers and improving the welding effect of the device; at the same time, the switching sequence of the air inlet valve and the air outlet valve can be changed, so that the pressure nozzle is converted into an air suction effect, and the harmful gases generated by welding can be absorbed, filtered and discharged according to different welding requirements, so as to purify the gas and prevent the harmful gases generated during welding from affecting the environment, further improving the safety and effect of the device during use, and reducing the limitations of the device during use;

[0023] (4) When the driving disc is rotating, the driving blocks on it can be limited to rotate in the driving grooves on the protective box, so as to limit the rotation of the driving disc, avoid the shaking of the driving disc during rotation, and cause the workpiece to shake during flipping, thereby improving the stability of the workpiece and the driving disc during rotation; at the same time, it can avoid the unstable rotation of the driving disc due to the uneven force applied to the driving disc when the staff needs to adjust the angle of the terminal, and support the driving disc, further improving the welding effect of the device on the terminal; at the same time, because the workpiece is clamped by the blocking clamping devices on the active shaft and the driven shaft, the active shaft drives the clamped workpiece to rotate while also driving the driven shaft to rotate, so that the top and bottom of the T-shaped rotating block on it slide at the auxiliary rotating ring, so as to further limit the rotation of the driven shaft and the workpiece, so as to avoid the shaking of the terminal during welding or flipping, which causes it to be unstable, thereby improving the stability of the terminal during flipping and welding, so that the use effect of the device is also improved;

[0024] (5) After the position adjustment of the workpiece is completed, the driving spring is reset by loosening the pulling square column so that it is no longer limited and resets, so that it can drive the pulling square column to reset and move in the gas transmission square cylinder, so that the gas inside can enter the bending pipe through the connecting pipe and the transfer square box. Since the strength of the driving spring is greater than that of the positioning spring, the reset gas in the bending pipe acts on the positioning cylinder to move it toward the driving disc, so that the positioning spring is in a buffering state, so that it can drive the rubber block to move toward the driving disc, so that the rubber block contacts the annular rubber pad, increasing the friction force on the driving disc, that is, the driving disc is clamped to avoid shaking or dislocation of the terminal when in use, thereby improving the welding effect of the device on the terminal, and ensuring the limiting effect of the driving disc. At the same time, the elastic rod body can also increase the limiting strength of the driving disc according to different limiting requirements, thereby improving the use effect of the device.

[0042] After the workpiece is fixed to the U-shaped base 1 by the blocking clamping device, it means that the terminal block can be connected to the wire and the welding operation can be performed; at the same time, by rotating the driving disc 15, the second small tooth 13 in the protective square box 8 is driven to rotate through the driving shaft 14, so that the second large tooth 12 is engaged and rotates, so that the rotation speed of the auxiliary shaft 11 on the second large tooth 12 is lower than that of the driving shaft 14, and then the first small tooth 10 on the auxiliary shaft 11 drives the engaged first large tooth 9 to rotate, and the size of the first large tooth 9 is still larger than the first small tooth 10, so that the rotation speed of the first large tooth 9 can be further reduced, so that the active shaft 2 can be driven to rotate slowly, the rotation speed of the active shaft 2 is reduced, and the workpiece (terminal block) clamped on the active shaft 2 can be slowly moved. Flipping is used to adjust the welding angle and position between the terminal and the wire, so as to avoid the poor accuracy of flipping the terminal, which may cause the terminal to be unable to stop at the appropriate welding position angle for use, thereby improving the welding accuracy of the terminal and the wire, and thus improving the welding effect of the device; and the gear ratio has the opportunity to achieve a degree where the driving disc 15 rotates one circle to drive the active shaft 2 to rotate 1° after a specific match, and the specific rotation angle is determined by different gear ratios. By using gears with different numbers of teeth and sizes to control how many degrees the driving disc 15 rotates one circle to drive the active shaft 2 to rotate, and when the angle of the terminal is greatly adjusted or when it is turned around, it can be achieved by rotating the terminal itself, which reduces the limitations of the device when in use and improves the use effect of the device;

[0043] It is worth mentioning that when the driving disc 15 is rotating, the driving rotating blocks 17 thereon are allowed to rotate within the driving rotating grooves 18 on the protective box 8, so that the rotation of the driving disc 15 can be limited, so as to avoid the shaking of the driving disc 15 during rotation, which causes the workpiece to shake when it is turned over, thereby improving the stability of the workpiece and the driving disc 15 during rotation; at the same time, it is avoided that when the staff needs to adjust the angle of the terminal, the driving disc 15 is not uniformly applied, resulting in unstable rotation, and the driving disc 15 is supported, further improving the docking of the device. The welding effect of the wire terminal; at the same time, since the workpiece is clamped by the blocking clamping devices on the active rotating shaft 2 and the driven rotating shaft 3, the active rotating shaft 2 drives the clamped workpiece to rotate while also driving the driven rotating shaft 3 to rotate, so that the top and bottom of the T-shaped rotating block 6 on it slide at the auxiliary rotating ring 7, so as to further limit the rotation of the driven rotating shaft 3 and the workpiece, and avoid the shaking of the terminal during welding or flipping, which leads to its instability, thereby improving the stability of the terminal during flipping and welding, and the use effect of the device is also improved.
