[0002] In the production process of a relay, a terminal wire needs to be welded on a moving spring piece of a terminal. In the prior art, in order to avoid the welding work of the terminal wire by a worker and to improve the production efficiency, a terminal wire welding machine is generally used for welding (usually resistance welding). However, in the prior art, the terminal is fed by a vibrating feeding disc, so that the moving spring piece of the terminal is bent due to vibration and collision during the feeding process, which affects the subsequent welding work and the welding quality. In addition, during the welding process, the moving spring piece pin and the terminal wire conductor are not welded well due to the rapid and continuous welding of the welding machine, which results in insufficient welding strength between the moving spring piece and the terminal wire, and causes the moving spring piece pin and the terminal wire conductor to have welding quality problems, resulting in a large amount of rework after the subsequent relay assembly.

[0028] The following describes the specific operation of this embodiment: It should be noted that the conveyor belt 102 is connected to the output channel of the vibrating feeder. The machine base 1 is equipped with a terminal wire conveying mechanism, a wire stripping mechanism, and a clamping and feeding mechanism. The terminal wire conveying mechanism conveys the terminal wire 5 to the wire stripping mechanism. The wire stripping mechanism, in conjunction with the clamping and feeding mechanism, performs fixed-point and fixed-length stripping and cutting of the terminal wire 5. Then, the clamping and feeding mechanism clamps the stripped and cut terminal wire 5 and connects the exposed conductor at the end of the terminal wire 5 with the pin of the moving spring 4. The vibrating feeder, terminal wire conveying mechanism, wire stripping mechanism, and clamping and feeding mechanism are all existing mature technologies and are not shown in the figure. In use, the external vibrating feeding tray feeds the terminals 3 one by one onto the conveyor belt 102. The movable spring 4 pins on the terminals 3 are supported on the mounting plate 101 in front. As the conveyor belt 102 rotates, the terminals 3 move from right to left into the welding range of the resistance welding machine 2. After the terminals 3 move into the welding range of the resistance welding machine 2, that is, when the leftmost movable spring 4 pin of the terminal 3 is directly opposite the welding head of the resistance welding machine 2 and is supported on the top block 2001 of the resistance welding machine 2, the conveyor belt 102 stops rotating. The clamping and feeding mechanism feeds the exposed conductor at the end of the terminal wire 5 to the movable spring 4 pin of the terminal 3. In this embodiment, taking the movable spring 4 with four pins as an example, the clamping and feeding mechanism clamps all four terminal wires 5 at once and makes the four The exposed conductors at the ends of the terminal wires 5 are simultaneously connected to the pins of the moving spring 4. Then, the clamping and feeding mechanism remains stationary, and the resistance welding machine 2 and the top block 2001 move laterally via the moving platform to weld the pins of the moving spring 4 one by one, so that the exposed conductors at the ends of the four terminal wires 5 are welded to the pins of the moving spring 4 one by one. After the welding is completed, the clamping and feeding mechanism stops clamping the terminal wires 5, and at the same time, the resistance welding machine 2 and the top block 2001 reset. The conveyor belt 102 continues to run, conveying the moving spring 4 of the welded terminal wires 5 along with the corresponding terminal 3 to the left, away from the welding range of the resistance welding machine 2, for unloading. At this time, the next terminal 3 moves into the welding range of the resistance welding machine 2, and the above welding operation is repeated to weld the terminal wires 5 to the pins of the moving spring 4 of the subsequent terminal 3.

[0029] During the movement of the terminal 3, in order to prevent the terminal 3 from being dislodged from the conveyor belt 102 due to mechanical vibration, and to avoid the problems of terminal 3 position deviation and stacking, the upward movement of the moving terminal 3 is restricted by the L-shaped limiting plate 103. At the same time, by setting rubber isolation strips 10201, and when the external vibrating feeding tray transports the terminal 3 one by one onto the conveyor belt 102, the terminal 3 is positioned between two adjacent rubber isolation strips 10201. The rubber isolation strips 10201 restrict the left and right movement of the moving terminal 3, ensuring the stable transport of the terminal 3 and ensuring the stable progress of the welding work.

[0030] As the terminals 3 move one by one into the welding range of the resistance welding machine 2, the appearance of the moving spring 4 pin on the terminal 3 is inspected by the first visual detector 201 on the right (mainly to detect whether the moving spring 4 pin is bent); after the terminal wire 5 is welded to the moving spring 4 pin of the terminal 3, the welding quality is inspected by the first visual detector 201 on the left (mainly to detect the appearance of the weld between the moving spring 4 pin and the conductor of the terminal wire 5); during the welding process of the terminal 3, if the first visual detector 201 on the right detects that the moving spring 4 pin of the terminal 3 is bent, after the terminal 3 moves to be directly opposite the push block 204 on the right, the first driving member 203 on the right quickly pushes the corresponding push block 204 backward, so that the terminal 3 falls into the first collection frame 205 through the notch opened on the mounting plate 101 and the L-shaped limiting plate 103, and then the first driving member 203 on the right quickly pulls the corresponding push block 204 to reset; after the terminal wire 5 is welded to the moving spring 4 pin of the terminal 3, if the left When the first visual detector 201 detects a defect in the appearance of the weld between the pin of the moving spring 4 and the conductor of the terminal wire 5, when the terminal 3 moves to be directly opposite the push block 204 on the left, the first driving member 203 on the left quickly pushes the corresponding push block 204 backward, so that the terminal 3 falls into the second collection frame 206 through the notch opened on the mounting plate 101 and the L-shaped limiting plate 103. Then, the first driving member 203 on the left quickly pulls the corresponding push block 204 to reset. This avoids the problem of bending of the pin of the moving spring 4 affecting the subsequent welding work and welding quality, and avoids the large-scale rework after the subsequent relay assembly due to welding quality problems between the pin of the moving spring 4 and the conductor of the terminal wire 5. Note that the distance that the conveyor belt 102 drives the terminal 3 to move to the left each time is equal to the distance between the back sides of two adjacent rubber isolation strips 10201. That is, the terminal 3 moves to the left by a fixed length. That is, it is only necessary to set the push block 204 to be directly opposite the terminal 3 after the fixed length movement to ensure that the terminal 3 is directly opposite the push block 204 after the movement.

[0031] Furthermore, to ensure the weld strength between the pin of the moving spring 4 and the conductor of the terminal wire 5, after the terminal wire 5 is welded to the pin of the moving spring 4 of terminal 3, as terminal 3 moves to the left, after all the terminal wires 5 on terminal 3 have contacted the U-shaped plate 302, the two second driving members 301 jointly push the U-shaped plate 302 upward to push the terminal wire 5 upward. At the same time, the second vision detector 303 detects whether the weld between the pin of the moving spring 4 and the conductor of the terminal wire 5 is firm after the terminal wire 5 is pushed upward, ensuring the weld strength between the pin of the moving spring 4 and the conductor of the terminal wire 5, and facilitating subsequent adjustments to welding parameters and maintenance of welding equipment based on the detected strength data. Note that the detection standard is: after the U-shaped plate 302 pushes the terminal wire 5 upward, if only the end... If the conductor of the sub-wire 5 remains firmly connected to the pin of the moving spring 4 without significant change, it indicates a strong weld between the pin of the moving spring 4 and the conductor of the terminal wire 5. Conversely, if the conductor of the terminal wire 5 becomes loose or detached from the pin of the moving spring 4, it indicates an unsatisfactory weld. Note that the distance by which the second drive unit 301 pushes the U-shaped plate 302 upward is set in advance by the operator according to requirements. Note that while the second drive unit 301 pushes the U-shaped plate 302 upward to test the weld strength between the pin of the moving spring 4 and the conductor of the terminal wire 5, the resistance welding machine 2 welds the terminal wire 5 to the moving spring 4 of the subsequent terminal 3. When the resistance welding machine 2 completes one welding operation and resets, the second drive unit 301 pulls the U-shaped plate 302 to reset, avoiding obstruction of the conveyor belt 102.

[0032] Furthermore, by setting the length of the U-shaped plate 302 to simultaneously detect the terminal wires 5 welded to the four terminals 3, and ensuring that the detection range of the second visual detector 303 completely covers the U-shaped plate 302, when detecting the welding firmness between the pin of the moving spring 4 and the conductor of the terminal wire 5, the second driving member 301 can drive the U-shaped plate 302 to push the terminal wires 5 upward after all four adjacent terminals 3 welded to the U-shaped plate 302 have contacted the U-shaped plate 302, thereby reducing the operating frequency of the second driving member 301 and improving its service life.

[0033] After the weld strength test is completed, as terminal 3 drives the connected moving spring 4 and terminal wire 5 to continue moving to the left, the first visual detector 201 on the left detects the weld quality on the pin of the moving spring 4, and the first driving component 203 cooperates with the push block 204 to remove the unqualified terminal 3. Note that after the weld strength test, the weld quality on the pin of the moving spring 4 will be further exposed, making it easier for the first visual detector 201 to detect the weld quality on the pin of the moving spring 4.

[0034] Furthermore, to prevent the U-shaped plate 302 from pushing the terminal wire 5 upwards and causing the pins of the movable spring 4 to bend upwards, thus affecting the weld strength test and requiring subsequent correction by personnel, a limiting plate 401 restricts the rear half of the movable spring 4 pins at the weld point when the U-shaped plate 302 is driven upwards by the second driving member 301 to push the terminal wire 5 upwards. Simultaneously, a limiting block 402 restricts the weld point of the movable spring 4 pins. That is, the limiting plate 401 and the limiting block 402 work together to prevent the U-shaped plate 302 from causing the terminal wire 5 to bend upwards. The upward bending of the pin of the movable spring 4 affects the detection of the weld strength; more specifically, the distance between the lower side of the limiting plate 401 and the upper side of the front mounting plate 101 is equal to the thickness of the pin of the movable spring 4, and the distance between the lower side of the limiting block 402 and the upper side of the pin of the movable spring 4 is left with the thickness of the conductor of the terminal wire 5, so as to avoid the limiting block 402 blocking the movement of the pin of the movable spring 4; at the same time, as the welded terminal 3 moves to the left, after the terminal wire 5 welded to the terminal 3 has contacted the U-shaped plate 302, the conductor of the terminal wire 5 is located between two adjacent limiting blocks 402, so as to avoid blocking the detection of the second visual detector 303.

[0035] Because, to prevent the limiting block 402 from blocking the movement of the movable spring 4 pin, the thickness of the terminal wire 5 conductor is left between the lower side of the limiting block 402 and the upper side of the movable spring 4 pin, the movable spring 4 pin still has a slight upward bend when the U-shaped plate 302 pushes the terminal wire 5 upward. Therefore, after the welding firmness test is completed, as the conveyor belt 102 runs, the terminal 3 will drive the movable spring 4 and the terminal wire 5 connected to it to continue to move to the left. At this time, the pressure roller 505 squeezes and flattens the movable spring 4 pin to prevent the movable spring 4 pin from bending and affecting its use. It needs to be corrected by the staff. Specifically, initially, the first connecting block 504, under the action of the spring 503, makes the pressure roller 505 tightly connected to the upper side of the front mounting plate 101. During the process of terminal 3 moving to the left, after the welding firmness test is completed, the movable spring 4 and terminal wire 5 connected to it will continue to move. The pin of the movable spring 4 will contact the pressure roller 505 and apply an upward pushing force to the pressure roller 505. As the pin of the movable spring 4 moves, the connecting rod 502, the first connecting block 504 and the pressure roller 505 will be forced to move upward, and the spring 503 will be compressed. Due to the pushing force released after the spring 503 is compressed, the pressure roller 505 will automatically perform a leveling operation on the pin of the movable spring 4 during the movement. At the same time, since the pressure roller 505 is rotatably connected to the first connecting block 504, the friction is reduced, and the pressure roller 505 will not loosen the conductor of the firmly welded terminal wire 5 during the leveling process of the pin of the movable spring 4.

[0036] Furthermore, considering that during the testing of the solder joint strength between the pin of the moving spring 4 and the conductor of the terminal wire 5, the poorly soldered terminal wire 5 will detach from the pin of the moving spring 4 and fall onto the machine base 1 during the testing process; therefore, by opening a flow guide collection groove 1002 on the side of the T-shaped mounting plate 1001 facing the front mounting plate 101, and placing the flow guide collection groove 1002 below the U-shaped plate 302, the flow guide collection groove 1002 collects the terminal wire 5 that detaches during the solder joint strength testing process, and discharges the collected terminal wire 5 into an external collection frame through the discharge frame 701 for recycling.

[0037] Furthermore, considering that during the testing of the solder joint strength between the pin of the moving spring 4 and the conductor of the terminal wire 5, some terminal wires 5 with poor solder joints remain connected to the pin of the moving spring 4 during the testing process, after the solder joint strength test is completed, the terminal 3 moves the connected moving spring 4 and terminal wire 5 to the left. During the leveling process of the pin of the moving spring 4, the pressure roller 505, in conjunction with the rubber sheet 602, causes the poorly soldered terminal wires 5 to detach from the pin of the moving spring 4, reducing the workload of subsequent workers.

[0038] Example 2: Based on Example 1, as follows Figure 6 , Figure 10 , Figure 11 and Figure 12 As shown, it also includes a hinge 801 fixed between the output end of the second drive member 301 and the U-shaped plate 302.

[0039] It also includes an electric rotating rod 901 connected to the right end of the U-shaped plate 302; another electric rotating rod 901 is connected to the right end of the limiting plate 401 through a connecting plate, the horizontal central axes of the two electric rotating rods 901 coincide in the vertical direction, and both electric rotating rods 901 are located in front of the pin of the moving spring 4; the electric rotating rod 901 is composed of a direct drive motor and a rod body, and the direct drive motor drives the rod body to rotate; the rotating ends of the two electric rotating rods 901 are staggered; the front mounting plate 101 is provided with a first clearance notch 10101, a second clearance notch 10102 and a third clearance notch 10103 in sequence, and the first clearance notch 10101, the second clearance notch 10102 and the third clearance notch 10103 are interconnected.

[0040] The following describes the specific operation of this embodiment: During the weld strength test, the U-shaped plate 302 can be pushed upward by the second drive member 301 on the left, while the second drive member 301 on the right remains stationary. This causes the U-shaped plate 302 to tilt to the left and down to the right under the action of the hinge 801. After the terminal wire 5 is welded to the pin of the moving spring 4 of the terminal 3, the weld strength test is automatically performed as the terminal 3 moves to the left, eliminating the need for the second drive member 301 to reciprocate, thus extending its service life. Note that the tilt angle of the U-shaped plate 302 is set and adjusted by the operator in advance according to the requirements. At the same time, by tilting the U-shaped plate 302 to the left and down to the right, the change of the welding point between the moving spring 4 and the terminal wire 5 at different lifting heights can be detected, allowing the operator to adjust the welding parameters and maintain the welding equipment based on the data. Note that the mounting plate 101 at the front has a first clearance notch 10101 to avoid interference with the change of state of the U-shaped plate 302.

[0041] Furthermore, after the clamping and feeding mechanism delivers the exposed conductor at the end of the terminal wire 5 to the pin of the moving spring 4 of the terminal 3, the two electric rotating rods 901 rotate in opposite directions to replace the clamping and feeding mechanism in clamping the end of the terminal wire 5. This frees the clamping and feeding mechanism from the work of stripping and cutting the terminal wire 5 when welding the next terminal 3, avoiding the need for the clamping and feeding mechanism to maintain the clamping state of the terminal wire 5 during welding. This optimizes the welding process, improves welding smoothness, and increases production efficiency. Note that in the initial state, the two electric rotating rods 901 are combined in a V-shape, and both electric rotating rods 901 are located in front of the pin of the moving spring 4. The resistance welding machine 2 will not interfere with the upper electric rotating rod 901, and through the first clearance notch 10101, the second clearance notch 10102, and the third clearance notch 10103 provided on the front mounting plate 101, it will not interfere with the lower electric rotating rod 901.

[0042] Furthermore, by misaligning the rotating ends of the two electric rotating rods 901, it is prevented that when the U-shaped plate 302 changes from a straight state to an inclined state, the two electric rotating rods 901 rotate towards each other to clamp the terminal wire 5, and are blocked by the terminal wire 5 near the rotating end of the electric rotating rod 901, thus preventing them from rotating to a straight state to clamp the remaining terminal wires 5.

[0043] Although the invention has been described with reference to exemplary embodiments, it should be understood that the invention is not limited to the disclosed exemplary embodiments. The scope of the following claims should be given the broadest interpretation so as to cover all variations and equivalent structures and functions.
