[0028] For ease of understanding, Figure 1 The diagram shows the structure of the connector terminal 52 before and after bending in this embodiment.

[0029] like Figure 2As shown, a connector terminal bending mechanism with shaping function is provided on an automatic connector assembly equipment. The automatic connector assembly equipment is provided with a transfer line 10 extending in the X direction. The connector terminal bending mechanism includes a bending component 20, a transfer component 30, a shaping component 40, and a base 60. A transfer slide 11 is formed on a Y-direction sidewall of the transfer line 10, which is adapted to the glue core 51 on the connector and extends in the X direction. Two or more terminals 52 extending in the Y direction and arranged in the X direction are arranged on the glue core 51. The end of the terminal 52 to be bent extends to the Y-direction outer side of the transfer slide 11.

[0030] like Figure 3 As shown, the material transfer assembly 30 is located at one end of the material transfer line 10 in the X direction, including a first drive device 31 and a first slide plate 32 connected to it in a transmission manner. The first slide plate 32 is provided with a guide plate 33, and the guide plate 33 is provided with a guide groove 34 that is connected to the material transfer slide and adapted to the core 51. After the connector semi-finished product on the material transfer line 10 is moved to the guide groove 34, the first drive device 31 can drive the first slide plate 32 to move in the Y direction and drive the product on the guide plate 33 to move synchronously.

[0031] In this embodiment, the base 60 is provided with a first slide rail 35 that is adapted to the first slide plate 32 and extends along the Y direction. The first slide rail 35 is composed of two L-shaped support plates 36 located on the sides of the Y-direction ends of the first slide plate 32. The lateral arms of the two support plates 36 can be detachably fixed on the base 60, and their longitudinal arms extend in the Z direction and are provided with Y-direction extending limiting rods 37. Limiting plates 38 are provided on the Y-direction sides of the two limiting rods 37. The limiting plates 38 can be detachably fixed on the first slide plate 32.

[0032] like Figure 4 As shown, the bending assembly 20 includes a rotating shaft 21 located below the Y-direction side of the guide groove 34 and extending along the X-direction. A bending plate 22 is hinged to the rotating shaft 21. The bending plate 22 is connected to the second driving device 23 and can rotate on the rotating shaft under its drive to bend the terminal 52 of the product on the guide groove 34 facing the bending plate 22.

[0033] In this embodiment, the second driving device 23 is a linear cylinder hinged to the base 60, and its output end is hinged to the bending plate 22. Two positioning posts 24 extending in the Z direction and arranged in the X direction are provided on the base 60 below the Y-direction side of the third sliding plate 44. A rotating shaft 21 is provided on the opposing sidewalls of the two positioning posts 24. The end of the bending plate 22 facing the guide groove 34 has three protrusions arranged in the X direction: a first protrusion 25, a second protrusion 26, and a third protrusion 27. The first protrusion 25 and the third protrusion 27 are each hinged to a rotating shaft 21. A roller 28 extending in the X direction and rotatable relative to the Y-direction end of the second protrusion 26 is mounted on it. The length of the roller 28 is greater than the maximum X-direction distance between the two terminals 52 on the connector. For ease of production and assembly, the second protrusion 26 is detachably fixed to the bending plate 22, and its end extending to the outside of the bending plate 22 has a U-shaped structure, with the roller 28 mounted between its two sidewalls. To prevent the terminal from deforming during the bending process, a support plate supporting the terminal 52 from the bottom is provided on the side of the roller 28 in the Y direction on the base 60.

[0034] like Figure 5 As shown, the shaping assembly 40 includes a column 41 disposed on the first slide plate 32, a third drive device 42 and a third slide rail 43 extending in the Z direction disposed on the column 41, a third slide plate 44 disposed on the third slide rail 43 and drivenly connected to the third drive device 42, the lower end of the third slide plate 44 extends above the guide groove 34 and the bending plate 22 and is adapted to the product on the guide groove 34; the third drive device 42 can drive the third slide plate 44 to move in the Z direction to guide the terminal 52 of the product on the guide groove 34.

[0035] like Figure 6 As shown, in this embodiment, a shaping block 45 is detachably fixed to the lower end of the third slide plate 44. A forming part 1 is formed on the Y-direction sidewall of the shaping block 45, extending obliquely downward and outward. A positioning part 2 and a pressing part 3 are arranged along the Y-direction at the bottom end of the forming part 1. The positioning part 2 faces the bending plate 22 and includes a plurality of fourth protrusions 46 arranged in the X-direction. A terminal 52 can be accommodated between each pair of adjacent fourth protrusions 46. The pressing parts 3 are all adapted to the upper end of the core 51.

[0036] like Figure 3-4 As shown, in this embodiment, the first driving device 31, the second driving device 23, the first sliding plate 32 and the rotating shaft 21 are all mounted on the base 60.

[0037] During operation, the transfer line 10 drives the connector core 51 to slide from the transfer slide 11 into the guide groove 34. After it is in place, the first drive device 31 drives the first slide plate 32 to move the guide plate 33 along the Y direction to approach the bending plate 22, and sends the area to be bent of the terminal 52 on the product in the guide groove 34 to the roller 28. Simultaneously, the third drive device 42 drives the third slide plate 44 to move the shaping block 45 along the Z direction downward to approach the product in the guide groove 34 until the pressing part 3 presses the core 51, each fourth protrusion 46 on the positioning part 2 extends to the middle of the two ends 52 and presses the terminal 52 against the support plate on the base 60, and the bottom end of the forming part 1 moves to the side of the terminal 52 to guide its bending. Simultaneously, the second drive device 23 drives the bending plate 22 to flip upward and bend the terminal 52 simultaneously. After bending and forming, the third drive device 42 drives the shaping block 45 to move upward away from the bent terminal 52 and return to its original position. The second drive device 23 drives the bending plate 23 to flip downward and return to its original position. The first drive device 31 drives the guide plate 33 to move the bent product on it to its original position and make the guide groove 34 connect with the transfer slide 11, thus completing the terminal bending and shaping action of one product. The product on the transfer slide 11 pushes the bent product in the guide groove 34 forward to leave the guide groove 34 or enter the inspection station. At the same time, the next product to be bent flows into the guide groove 34. This process is repeated to sequentially bend the terminals 52 on each product on the transfer line 10.

[0038] This utility model has a simple structure and compact layout. By providing a guide groove 34 at the end of the X-direction extending material transfer slide 11 that is adapted to the product and can be translated along the Y-direction, and a shaping block 45 above the guide groove 34 that can move along the Z-direction and press the product on it, and a bending plate 22 that can be flipped up and down on the Y-direction side of the guide groove 34, it can cooperate with the material transfer line 10 to continuously bend the terminals 52 on each connector product one by one, which is efficient and fast. By providing a pressing part 3, a positioning part 2 and a forming part 1 on the shaping block 45, the core 51 and the terminal 52 can be fixed before bending the terminal 52, avoiding the problem of deformation of the longitudinal bending area and the transverse guiding area of ​​the terminal 52 due to the positional displacement of the product, improving the bending yield, and eliminating the need for subsequent shaping, simplifying the production process, improving production efficiency and reducing production costs.

[0039] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
