[0031] Reference Figure 1 In an embodiment of the present utility model, a terminal rotation bending structure includes a machine 100, the machine 100 is provided with a workbench 103, a pressing device 110 and a bending device 120, the workbench 103 is provided with a terminal 105, the pressing device 110 is provided with a pressing block 111 that can extend and press the terminal 105 located on the workbench 103, the terminal 105 includes a bending section 106 and a base section 107, the bending device 120 is provided with a slider 121, and the slider 121 is provided with a pressing block 111. The side wall of the machine 100 has an arc-shaped track. When the pressure block 111 presses against the base section 107, the slider 121 can slide along the track and push the base section 107 toward the pressure block 111 through the actuator 122. Since the slider 121 moves along the arc track, the actuator 122 can reduce the relative friction between the two when pushing the bending section 106, thereby avoiding scratching the electroplated layer of the terminal 105, so as to realize the process of bending the terminal 105 after electroplating.

[0032] Specifically, during processing, the terminals 105 are densely arranged on the material strip, the material strip with the terminals 105 is laid on the workbench 103, the base section 107 is fixed on the material strip, and the bent section 106 is suspended at one end of the base section 107. Figure 2 and Figure 3 The workbench 103 is provided with an operating hole 104, and the actuator 122 can pass through the operating hole 104 to push against the bottom side wall of the bending section 106, and bend the bending section 106 toward the pressing block 111. Figure 4 It can be understood that a plurality of actuators 122 are provided on the slider 121. In this embodiment, at least three mutually spaced actuators 122 are provided on the slider 121 along the length direction of the material strip. By providing a plurality of actuators 122, a plurality of terminals 105 can be bent at the same time, thereby improving processing efficiency.

[0033] It can be understood that the slider 121 is driven by the motor to move along the track. Specifically, the bending device 120 includes a driving wheel 125 and a connecting rod 124. The driving wheel 125 is located at the lower part of the workbench 103. One end of the connecting rod 124 is rotatably connected to the radial periphery of the driving wheel 125, and the other end is rotatably connected to the slider 121. When the driving wheel 125 rotates back and forth, it can drive the connecting rod 124 to move up and down, thereby pushing the slider 121 to move back and forth along the track.

[0034] Furthermore, the track includes a first slide groove 101 and a second slide groove 102. The first slide groove 101 is located on the side of the second slide groove 102 facing the workbench 103. The centers of the track circles of the first slide groove 101 and the second slide groove 102 coincide and are located on the side close to the workbench 103, so that the slider 121 can slide around the workbench 103. Correspondingly, a plurality of rollers 123 are provided on the slider 121. The rollers 123 are embedded in the second slide groove 102, and their radial outer walls roll against the side walls of the second slide groove 102. It can be understood that there is a gap between the second slide groove 102 and the rollers 123. When the slider 121 moves, the outer wall of the roller 123 rolls against the inner wall of any side of the second slide groove 102, thereby guiding the sliding track of the slider 121. In this embodiment, at least three rollers 123 are provided to prevent the slider 121 from rotating. Further, referring to Figure 5 The connecting rod 124 is provided with a connecting pin 126 connected to the slider 121. The connecting pin 126 is inserted into the first chute 101, and its radial outer wall can roll against the side wall of the first chute 101, thereby guiding the movement trajectory of the connecting rod 124. Furthermore, a hinge 130 is provided at one end of the connecting rod 124 connected to the slider 121, which enables the connecting rod 124 and the slider 121 to be hingedly connected. The connecting pin 126 is mounted on the hinge 130. It is understood that the hinge 130 is a fisheye joint to achieve a rotational connection. It is understood that the machine 100 is provided with a cavity 108, and the slider 121 is movable within the cavity 108. The track is provided on both sides of the machine 100 and connected to the cavity 108. The rollers 123 of the slider 121 are provided on both sides. The rollers 123 on both sides are embedded in the second chute 102, which helps to improve the operating stability of the slider 121.

[0035] It is understood that the drive wheel 125 is provided with an adjustment block 127 that can move in the radial direction of the drive wheel 125. The end of the connecting rod 124 is hinged to the adjustment block 127. When the position of the adjustment block 127 is adjusted, the swing radius of the connecting rod 124 around the drive wheel 125 can be adjusted, thereby adjusting the height of the connecting rod 124 reaching the top dead center position during the bending process, thereby adjusting the position of the slider 121 after bending, and thus adjusting the bending angle of the terminal 105. Furthermore, the drive wheel 125 is provided with a sensor plate 129 that extends outward in the radial direction of the drive wheel 125. The machine 100 is provided with a zero position sensor 109. When the drive wheel 125 rotates and brings the sensor plate 129 close to the zero position sensor 109, the zero position sensor 109 detects the sensor plate 129, and the drive wheel 125 is at a preset zero position. At the same time, the slider 121 is at a preset initial position, making it easy to reset the bending device 120. It is understandable that the machine 100 is provided with a driving motor 128 , which is used to drive the driving wheel 125 to rotate. In this embodiment, the driving motor 128 and the driving wheel 125 are respectively provided on two sides of the machine 100 .

[0036] Reference Figure 2 The pressing device 110 is provided with a lifting block 112 and a driving block 113. The pressing block 111 is fixed to the end of the lifting block 112 near the workbench 103. The driving block 113 is connected to the machine 100 by sliding horizontally, and the lifting block 112 is connected to the machine 100 by sliding vertically. The driving block 113 is provided with an inclined driving groove 114. The lifting block 112 is provided with a driving shaft 115 inserted into the driving groove 114. When the driving block 113 moves, it can drive the driving shaft 115 to move up and down through the driving groove 114, thereby realizing the lifting and lowering of the lifting block 112, and finally realizing the lifting and lowering movement of the pressing block 111. It can be understood that a driving cylinder 116 is provided on the pressing device 110, and the driving cylinder 116 can drive the driving block 113 to move.
