DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] like Figure 1-Figure 5 As shown, this embodiment provides a terminal pin correction device, which is arranged on one side of the terminal conveying mechanism 1. The correction device includes a bracket 10 and a correction component 20.

[0025] Specifically, such as Figures 1-4 As shown, the bracket 10 includes an L-shaped support 11 and a horizontal plate 12. The front end of the horizontal part of the L-shaped support 11 faces one side of the terminal conveying mechanism 1. The horizontal plate 12 is perpendicular to the top of the L-shaped support 11 and corresponds to the horizontal part of the L-shaped support 11. A group of symmetrical and spaced guide grooves 111 are opened in the horizontal part of the L-shaped support 11. The width between the two adjacent sides of a group of guide grooves 111 is the same as the pin width of the terminal 2. A group of guide grooves 111 are arranged along a vertical direction perpendicular to the L-shaped support 11, and a group of guide grooves 111 are connected to the front end of the horizontal part of the L-shaped support 11. A first inclined surface 112 is provided on one side of the inner bottom surface of a group of guide grooves 111, and the first inclined surface 112 is arranged on the side away from a group of guide seats 111 and inclined toward the symmetrical center line direction of a group of guide grooves 111.

[0026] The orthopedic assembly 20 includes a cylinder 21, a connecting seat 22, a pressure plate 23, a set of orthopedic plates 24, and a spring 25. The cylinder 21 is vertically arranged, and the upper end of the cylinder 21 shell is connected to the bottom surface of the horizontal plate 12. The output end of the cylinder 21 is vertically downwardly connected to the top surface of the connecting seat 22. The pressure plate 23 is protruding from the center of the bottom surface of the connecting seat 22, and the direction of the pressure plate 23 is consistent with the arrangement direction of the set of guide seats 111. The connecting seat 22 is recessed upward from the bottom. The upper ends of the set of orthopedic plates 24 are rotatably connected to the inner wall of the connecting seat 22, and the lower ends extend vertically downward from the bottom of the connecting seat 22. The set of orthopedic plates 24 are respectively located on both sides of the pressure plate 23. The outer sides of the lower ends of the set of orthopedic plates 24 are respectively provided with third inclined surfaces 246, and the third inclined surfaces 246 match the first inclined surfaces 112. The spring 25 is provided on the side above the pressure plate 23, and the two ends of the spring 25 are respectively connected to the opposite sides of a group of corrective plates 24. In normal state, under the action of the spring 25, the group of corrective plates 24 contacts the inner wall of the connecting seat 22, so that the lower ends of the group of corrective plates 24 are opened in a trumpet shape, and after opening, the distance between the outer walls of the lower ends of the group of corrective plates 24 is smaller than the distance between the side walls of the group of guide seats 111 away from each other.

[0027] Specific operation method:

[0028] Start the terminal conveying mechanism 1 to move the pins of the terminal 2 onto the L-shaped support 11 and between a group of guide grooves 111. Start the cylinder 21 to move the cylinder 21 vertically downward. A group of corrective plates 24 are inserted downward along the corresponding group of guide grooves 111, so that the group of corrective plates 24 are brought close to each other under the action of the group of guide grooves 111, and are close to the two sides of the pressure plate 23 under the action of the first inclined surface 112, so that the group of corrective plates 24 correct the two sides of the pins of the terminal 2. When the lower end of the group of corrective plates 24 is inserted into the bottom of the group of guide grooves 111, the pressure plate 23 acts on the top surface of the pin of the terminal 2, thereby correcting the upper and lower surfaces of the pin of the terminal 2, thereby completing the pin correction of the terminal 2. The structure is simple and the operation is easy.

[0029] Specifically, such as Figure 4-5 As shown, in order to improve the correction accuracy of the pins on both sides of the terminal 2, a group of correction plates 24 include an arc seat 241, a vertical surface 242, a second inclined surface 243, and a vertical plate 244. The arc seat 241 is rotatably connected to the inner wall of the connecting seat 22, and the vertical surface 242 is provided on the opposite side of a group of correction plates 24, and the upper side edge of the vertical surface 242 is tangent to the arc seat 241. When a group of correction plates 24 move closer to the two sides of the pressure plate 23 under the action of a group of guide grooves 111, the vertical surfaces 242 of a group of correction plates 24 fit together, thereby vertically maintaining a group of correction plates 24 on both sides of the pressure plate 23, avoiding wear of the adjacent side of a group of guide grooves 111 or wear of both sides of the pressure plate 23 after long-term use, which causes a group of correction plates 24 to deviate toward its symmetrical midline when correcting the pins on both sides of the terminal 2, thereby crushing or injuring the pins on both sides of the terminal 2.

[0030] The upper end of the second inclined surface 243 is connected to the lower side of the vertical surface 242, and the lower side of the second inclined surface 243 is inclined away from the direction of the symmetry center line of a group of orthopedic plates 24. The lower side of the second inclined surface 243 is connected to the upper end of the vertical plate 244, and the two ends of the spring 25 are respectively connected to the opposite side of the vertical plate 244.

[0031] In order to prevent the spring 25 from tilting along its axis when compressed, an accommodating hole 245 is recessed on one side of the vertical plate 244 , and the two ends of the spring 25 are respectively connected to the bottom of the accommodating hole 245 .

[0032] The above description is only a preferred embodiment of the present invention and does not represent the only embodiment or limit the present invention. It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
