[0002] The network transformer mainly has the functions of signal transmission, impedance matching, waveform repair, signal noise suppression and high voltage isolation. Since there are multiple pins on both sides of the network transformer, the bending or deflection of the pins needs to be adjusted and corrected before packaging the network transformer.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1: A network transformer pin spacing fine-tuning device provided by the present invention includes a processing table 1, a lateral fine-tuning component, a longitudinal fine-tuning component and an auxiliary roller 4, see Figure 1-Figure 10 As shown, a discharge trough 10 for horizontally placing the network transformer 100 is provided on the top of the processing table 1, and a loading port 11 for pushing the network transformer 100 is provided on the left front side of the top of the processing table 1, and the bottom side of the loading port 11 is flush with the bottom side of the discharge trough 10, so as to facilitate pushing the network transformer 100. A lateral fine-tuning component is provided in the middle of the processing table 1, and the lateral fine-tuning component includes a mounting seat 2, an adjustment frame 21 and an adjustment roller 22. Two mounting seats 2 are symmetrically provided in the front and rear middle of the upper side of the processing table 1, an adjustment frame 21 is provided on the upper part of the mounting seat 2, and 7 adjustment rollers 22 are rotatably provided on the adjustment frame 21 at intervals. A longitudinal fine-tuning component is provided on the right side of the processing table 1, and the longitudinal fine-tuning component The parts include a support seat 3, a cylinder 31, a connecting frame 32, a base 33, an adjustment plate 34, an elastic member 35 and an oblique seat 36. A support seat 3 is provided on the right front side of the processing table 1. The upper part of the support seat 3 is equipped with a cylinder 31. The end of the telescopic rod of the cylinder 31 is provided with a connecting frame 32. Two rows of bases 33 are symmetrically arranged on the connecting frame 32. Adjustment plates 34 are slidably provided on the bases 33. An elastic member 35 is connected between the upper side of the adjustment plate 34 and the base 33. The elastic member 35 is made of elastic rubber and is strong and durable. An oblique seat 36 adapted to the adjustment plate 34 is symmetrically arranged on the upper right side of the processing table 1. Five auxiliary rollers 4 are rotatably provided on the two adjustment plates 34 of the same group.

[0034] For further explanation, please see Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the adjusting rollers 22 are arranged in order from small to large from left to right, which is conducive to adjusting the pins of the network transformer 100 with different degrees of deflection, and is highly practical. The corresponding auxiliary rollers 4 in the same group are symmetrically staggered and distributed to support the pins of the network transformer 100. The bevel seat 36 is set in a W shape, and the end of the adjusting plate 34 is provided with a bevel that is compatible with the bevel of the bevel seat 36.

[0035] Push the network transformer 100 from the loading port 11 into the discharge trough 10, and push the network transformer 100 along the discharge trough 10 by pushing from left to right. When the pins on the network transformer 100 contact the adjusting rollers 22 in turn, the squeezing effect of the adjusting rollers 22 with different diameters can realize the horizontal adjustment correction of the pins of the network transformer 100, which is conducive to fine-tuning the front and rear sides of the pins of the network transformer 100. When the network transformer 100 is pushed further so that the pins on it are located between the corresponding two adjustment plates 34, the cylinder 3 is started. 1 makes its telescopic rod extend, and the connecting frame 32 will drive the base 33, the adjustment plate 34 and the elastic member 35 to move downward synchronously. When the lower end of the adjustment plate 34 contacts and cooperates with the bevel seat 36, the bevel seat 36 pushes the adjustment plate 34, so that the corresponding two adjustment plates 34 are close to each other to squeeze the pins of the network transformer 100, so that the left and right sides of the pins of the network transformer 100 can be fine-tuned and corrected, and while the adjustment plate 34 moves downward, the corresponding auxiliary roller 4 supports the front and rear sides of the pins of the network transformer 100 to achieve synchronous limit. In this way, by correcting the pins of the network transformer 100 horizontally and vertically, the pins of the network transformer 100 can be corrected at one time, and the pins are less affected by the offset amplitude, which is convenient to use and highly practical, thereby helping to improve the efficiency of correcting the pins of the network transformer 100.

[0036] Example 2: Based on Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9 As shown, it also includes a support 5, a servo motor 51, a rotating shaft 52, a transmission component 53 and a push block 54. A support 5 is provided on the left rear side of the upper part of the processing table 1. A servo motor 51 is installed on the support 5 for intermittently controlling the network transformer 100 to push. Rotating shafts 52 are rotatably provided on the left and right sides of the upper part of the processing table 1. The rotating shaft 52 on the left is connected to the output shaft of the servo motor 51. A transmission component 53 is provided between the two rotating shafts 52. The transmission component 53 is mainly composed of a conveyor belt and two belt rollers. The two belt rollers are respectively mounted on the rotating shaft 52. The conveyor belt is wound around the two belt rollers. Push blocks 54 for pushing the network transformer 100 to move horizontally are provided at intervals on the conveyor belt.

[0037] It should be further explained that the fixing frame 6, the limiting frame 61 and the torsion spring 62 are also included. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.10 , Fig.11 and Fig.12 As shown, a fixing frame 6 is provided on the upper right side of the processing table 1, and a limit frame 61 for limiting the end of the network transformer 100 is rotatably provided in the middle of the fixing frame 6 through two connecting shafts, and a torsion spring 62 for resetting is sleeved on the connecting shaft, one end of the torsion spring 62 is connected to the fixing frame 6, and the other end of the torsion spring 62 is connected to the limit frame 61.

[0038] It should be further explained that the rack 7, the rotating rod 71 and the overrunning clutch gear 72 are also included. Figure 1 , Figure 2 , Figure 3 , Fig.10 , Fig.11 and Fig.12 As shown, the outer ends of the two connecting shafts are connected to a rotating rod 71, and the two rotating rods 71 ​​are mounted with an overrunning clutch gear 72. Two racks 7 are symmetrically arranged on the front and back of the right side of the connecting frame 32, and the racks 7 can be moved downward to engage with the overrunning clutch gear 72.

[0039] It should be further explained that the supporting frame 8 and the limiting rod 81 are also included. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig.10 As shown, a support frame 8 is provided in the middle of the upper side of the processing table 1 , and a limiting rod 81 for clamping the upper end surface of the network transformer 100 is provided on the support frame 8 .

[0040] It should be further explained that a buffer block 9 is also included. Figure 1 , Fig.10 , Fig.11 and Fig.12 As shown, a buffer block 9 is provided on the limit frame 61, and the buffer block 9 contacts the right end of the limit rod 81. The buffer block 9 is made of rubber material and is used for buffering when the limit frame 61 is closed.

[0041] The servo motor 51 is started, and its intermittent operation is controlled. The transmission component 53 drives the push block 54 to transmit intermittently, so that the network transformer 100 placed in the discharge trough 10 can be intermittently pushed and loaded; the blocking effect of the limit frame 61 makes the pushed network transformer 100 just below the adjustment plate 34. When the telescopic rod of the cylinder 31 extends downward, the connecting frame 32 will drive the rack 7 thereon to move downward synchronously. When the rack 7 is engaged with the overrunning clutch gear 72, the outer ring of the overrunning clutch gear 72 will rotate with it. Since the rotating rod 71 is not affected and remains stationary, when the telescopic rod of the cylinder 31 is shortened and reset upward, the connecting frame 32 will drive the adjustment plate 34 and the rack 7 thereon to move upward and reset synchronously. The adjustment plate 34 is disengaged from the pin of the network transformer 100, and the rack 7 will be engaged with the overrunning clutch gear 72 again. When the gear 7 is closed, the overrunning clutch gear 72 drives the rotating rod 71 thereon to rotate so that the limit frame 61 flips upward by 90 degrees, and the torsion spring 62 is twisted accordingly. Under the continued pushing action of the transmission component 53 and the push block 54, the network transformer 100 with the pins corrected can be pushed out and unloaded. When the rack 7 is disengaged from the overrunning clutch gear 72, the elastic force of the torsion spring 62 drives the limit frame 61 to flip and reset in the opposite direction. Under the buffering action of the buffer block 9, the flipped and reset limit frame 61 can be buffered. Moreover, through the cooperation of the support frame 8 and the limit rod 81, the upper end surface of the network transformer 100 in the discharge trough 10 can be limited, which is beneficial for the network transformer 100 to maintain a stable state when being pushed. At the same time, it is more beneficial to improve the stability of the network transformer 100 when fine-tuning the pins, and ensure the quality of the pin adjustment.

[0042] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application.

At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
