Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of connector terminal shaping, in particular to a connector terminal shaping device. BACKGROUND

[0002] The connector terminal is an important component for electrical connection in electronic equipment, and its shape and size precision directly affect the reliability and stability of electrical connection.

[0003] Reference Figure 1 The connector terminal includes a terminal shell 11 and a terminal contact 12 embedded in the terminal shell. The terminal shell is in a cylindrical shape as a whole. In the related art, the terminal shell is formed by stamping a metal plate, and after stamping is completed, a long strip-shaped metal strip 13 is still retained at the tail end of the terminal shell. The tail ends of a plurality of terminal shells 11 are connected side by side with the same metal strip 13 to form a terminal string. The metal strip 13 is further stamped with a positioning hole 131 in the region corresponding to each terminal shell 11. When assembling the terminal shell 11 and the terminal contact 12, a stamping method is usually adopted, and the terminal contact 12 is punched into the terminal shell 11 by using a stamping punch. However, in the stamping process, there is a probability that the stamping punch will deform the front end opening of the terminal shell 11.

[0004] In view of the related art in the above, it is necessary to provide a device capable of restoring the shape of the terminal shell. Invention content

[0005] In order to restore the shape of the terminal shell, the present application provides a connector terminal shaping device.

When the terminal shell is located below the positioning assembly, the positioning assembly can press the terminal shell on the material moving track, and then the shaping assembly can shape the deformed terminal shell to restore the shape of the terminal shell. The shaped terminal string can be wound by the material collecting disc.

The bottom of the first positioning block is spaced apart in the length direction and provided with at least two first positioning grooves for pressing the terminal shell on the material moving track.

[0014] By adopting the technical scheme, the specific structure of the positioning assembly is disclosed. When the terminal string is located below the first positioning block, the first cylinder drives the first positioning block to move downwards, so that the first positioning groove abuts against the terminal shell, thereby pressing the terminal shell on the material moving track.

[0015] Optionally, the shaping assembly comprises a driving cylinder arranged on the shaping rack and located on one side of the material moving track, a driving seat arranged at the end of the piston rod of the driving cylinder, a shaping sleeve horizontally slidingly arranged on the driving seat, and a shaping striker. The extension direction of the piston rod of the driving cylinder is horizontally perpendicular to the length direction of the material moving track. The outer diameter of the shaping striker is matched with the inner diameter of the terminal shell, and the inner diameter of the shaping sleeve is matched with the outer diameter of the terminal shell.

[0016] By adopting the technical scheme, the specific structure of the shaping assembly is disclosed. The driving cylinder drives the driving block to move towards the material moving track, thereby driving the shaping striker and the shaping sleeve to move towards the terminal shell. When the shaping sleeve contacts the terminal shell, the terminal shell can be extruded into the shaping sleeve to shape the outer surface of the terminal shell. Then, the conveying mechanism drives the terminal string to move, so that the terminal shell whose outer surface has been shaped is conveyed to the position opposite to the shaping striker. The shaping striker can be inserted into the terminal shell to shape the inside of the terminal shell. The above steps can be repeated to shape the terminal shells on the terminal string in sequence.

[0017] Optionally, the driving base comprises a driving base plate, a mounting portion connected to one end of the driving base plate facing the material moving track, and a driving portion connected to the other end of the driving base plate away from the material moving track; the shaping sleeve is arranged in the mounting portion, the shaping sleeve is sleeved with a first nut on the side of the mounting portion away from the material moving track, and the shaping sleeve is further sleeved with a first spring on the end away from the material moving track, one end of the first spring abuts against the first nut and the other end abuts against the driving portion; the shaping punch is sleeved with a second nut on the side of the mounting portion away from the material moving track, and the shaping punch is further sleeved with a second spring on the end away from the material moving track, one end of the second spring abuts against the second nut and the other end abuts against the driving portion; the driving portion is provided with a first accommodation groove for inserting the shaping sleeve and a second accommodation groove for inserting the shaping punch.

[0018] By adopting the above technical scheme, the first nut, the first abutting spring and the first accommodation groove are arranged, so that when the shaping sleeve contacts the terminal shell, the first abutting spring can be compressed, the impact force between the shaping sleeve and the terminal shell is buffered, and damage to the terminal shell caused by direct rigid contact is avoided. The second nut, the second abutting spring and the second accommodation groove are arranged, so that when the shaping punch contacts the terminal shell, the second abutting spring can be compressed, the impact force between the shaping punch and the terminal shell is buffered, and damage to the terminal shell caused by direct rigid contact is avoided.

[0019] Optionally, the conveying mechanism comprises a first conveying assembly located at the starting end of the material moving track, a second conveying assembly located at the end of the material moving track, and a synchronous connecting rod connecting the first conveying assembly and the first conveying assembly; the first conveying assembly comprises a conveying cylinder arranged horizontally on the shaping rack, a first sliding block arranged at the end of the piston rod of the conveying cylinder, a first lifting cylinder arranged vertically on the side of the first sliding block facing the material moving track, and a first driving rod arranged at the end of the piston rod of the first lifting cylinder and used for inserting the positioning hole of the metal strip; the second conveying assembly comprises a second sliding block arranged in the shaping rack, a second lifting cylinder arranged on the side of the second sliding block facing the material moving track, and a second driving rod arranged at the end of the piston rod of the second lifting cylinder and used for inserting the positioning hole of the metal strip.

[0020] By adopting the technical scheme, the specific structure of the conveying mechanism is disclosed. When the terminal string is located on the material moving track, the first lifting cylinder drives the first driving rod to move downward and insert into the positioning hole of the metal strip, and the piston rod of the second lifting cylinder synchronously drives the second driving rod to move downward and insert into the positioning hole of the metal strip.

[0022] By adopting the technical scheme, the second positioning block can press the terminal shell against the material moving track, and then the outer diameter and the inner diameter of the front end opening of the terminal shell are detected by the detection probe to determine whether the size specification is met.

[0023] Optionally, the outer side of the detection probe is provided with a dust cover.

The extension range of the piston rod of the conveying cylinder 311 is equal to the distance between the two positioning holes 131 in the metal strip 13.

[0050] With reference to Figure 2 and Figure 5The shaping mechanism 4 comprises a positioning assembly 41 mounted on the material moving frame 22 and located on the upper side of the material moving track 221, and a shaping assembly 42 mounted on the mounting frame 23 and located on one side of the material moving track 221. The material moving frame 22 has a first mounting seat 224 for mounting the positioning assembly 41. The positioning assembly 41 comprises a first cylinder 411 mounted in the first mounting seat 224 and facing one side of the material moving track 221, and a first positioning block 412 mounted at the end of the piston rod of the first cylinder 411. The piston rod of the first cylinder 411 is arranged vertically downward towards the direction of the material moving track 221, so as to drive the first positioning block 412 to move vertically downward and abut against the material moving track 221. The bottom of the first positioning block 412 is spaced apart in the length direction and provided with at least two first positioning grooves 4121. In this embodiment, the first positioning grooves 4121 are provided with four. When the first cylinder 411 drives the first positioning block 412 to abut against the material moving track 221, the groove walls of the first positioning grooves 4121 can abut against the outer side wall of the terminal shell 11, so as to fix the terminal shell 11 on the material moving track 221.

[0051] With reference to Figure 2 and Figure 5 The shaping assembly 42 comprises a driving cylinder 421 fixed to the mounting frame 23 and arranged perpendicularly to the material moving track 221, a driving seat 422 connected to the end of the piston rod of the driving cylinder 421 and slidingly arranged on the mounting frame 23, a shaping sleeve 423 slidingly mounted horizontally on the driving seat 422, and a shaping striker 424 slidingly mounted horizontally on the driving seat 422. The piston rod of the driving cylinder 421 is arranged towards one side of the material moving track 221 and perpendicularly to the length direction of the material moving track 221. The driving cylinder 421 drives the driving seat 422 to slide towards the direction of the material moving track 221, so that the shaping sleeve 423 and the shaping striker 424 can abut against the terminal shell 11 located on the material moving track 221. In this embodiment, the shaping sleeve 423 is spaced apart and provided with two, and the shaping striker 424 is spaced apart and provided with two.

[0052] With reference to Figure 5 and Figure 6 The driving seat 422 comprises a driving bottom plate 4221, a mounting portion 4222 connected to the driving bottom plate 4221 and close to one side of the material moving track 221, and a driving portion 4223 connected to the driving bottom plate 4221 and away from one side of the material moving track 221.

[0054] With reference to Figure 5 and Figure 6 In order to avoid the shaping sleeve 423 from damaging the terminal shell 11 due to hard contact when contacting the terminal shell 11, the driving sleeve is sleeved with a first nut 4231 on the side away from the material moving track 221 in the mounting portion 4222, and the driving sleeve is also sleeved with a first spring 4232 on the end away from the material moving track 221. The driving portion 4223 is provided with a first accommodation groove 42231 on the side toward the mounting portion 4222, for inserting the end of the driving sleeve. One end of the first spring 4232 abuts against the first nut 4231, and the other end abuts against the driving portion 4223, so as to drive the shaping sleeve 423 to always have a tendency to move toward the material moving track 221. When the shaping sleeve 423 abuts against the terminal shell 11, the driving sleeve can be displaced a distance toward the driving portion 4223, the first nut 4231 can compress the first spring 4232, and at the same time, the shaping sleeve 423 can be inserted into the first accommodation groove 42231 on the end away from the material moving track 221, so as to avoid the hard contact between the shaping sleeve 423 and the terminal shell 11.

[0055] With reference to Figure 5 and Figure 6In order to avoid the shaping punch 424 from damaging the terminal shell 11 due to hard contact when contacting the terminal shell 11, the driving punch is sleeved with a second nut 4241 on the side away from the material moving track 221 in the mounting portion 4222, and the driving punch is also sleeved with a second spring 4242 on the end away from the material moving track 221.

One end of the second spring 4242 abuts against the second nut 4241 and the other end abuts against the driving portion 4223, so as to drive the shaping punch 424 to always move towards the material moving track 221. When the shaping punch 424 abuts against the terminal shell 11, the driving punch can be displaced towards the driving portion 4223 by a distance, the second nut 4241 can compress the second spring 4242, and at the same time, the shaping punch 424 can be inserted into the second accommodation slot 42232 on the end away from the material moving track 221, so as to avoid the hard contact between the shaping punch 424 and the terminal shell 11.

[0056] With reference to Figure 2 and Figure 7 The visual detection mechanism 5 is arranged on one side of the shaping mechanism 4 along the conveying direction of the material moving track 221. The visual detection mechanism 5 comprises a second cylinder 51, a second positioning block 52 mounted on the end of the piston rod of the second cylinder 51 and a detection probe 53 mounted on the top of the detection frame 24.

The bottom of the second positioning block 52 is provided with at least two second positioning grooves 521 spaced apart along the length direction. In this embodiment, the second positioning grooves 521 are provided with four. When the second positioning block 52 abuts against the material moving track 221, the groove wall of the second positioning groove 521 can abut against the terminal shell 11, so as to fix the terminal shell 11 on the material moving track 221.

[0057] With reference to Figure 2 and Figure 7 The detection probe 53 is arranged perpendicular to the length direction of the material moving track 221. When the second positioning block 52 presses the terminal shell 11 against the material moving track 221, the detection probe 53 can detect the opening of the terminal shell 11 by photographing. The detection frame 24 is also provided with a dust cover 54 covering the detection probe 53, and the dust cover 54 is open on the side towards the material moving track 221.

[0058] The removing mechanism 6 is arranged at one side of the visual inspection mechanism 5 along the conveying direction of the material moving track 221. The removing mechanism 6 comprises a third cylinder 61 mounted on the material moving frame 22 and a punch block 62 connected to the end of the piston rod of the third cylinder 61. The third cylinder 61 and the punch block 62 are both located above the material moving track 221, and the piston rod of the third cylinder 61 is arranged towards the material moving track 221. The material moving track 221 is provided with a material dropping groove 2213 penetrating through the upper and lower surfaces below the punch block 62, and the top of the material moving frame 22 is provided with a material dropping groove 226 opposite to the material dropping groove 2213. The workbench 21 is provided with a material collecting basket 63 below the material dropping groove 2213, and the upper end opening of the material collecting basket 63 is opposite to the lower end opening of the material dropping groove 2213. When the detection probe 53 detects an unqualified terminal shell 11, and when the unqualified terminal shell 11 is moved to the material dropping groove 2213, the piston rod of the third cylinder 61 extends downward to drive the punch block 62 to move downward, so as to knock off the unqualified terminal shell 11 from the metal strip 13 and make the unqualified terminal shell 11 enter the material collecting basket 63 through the material dropping groove 2213 and the material dropping groove 226.

[0059] With reference to Figure 2 The material collecting mechanism 7 comprises a material collecting frame 71 mounted on the top of the workbench 21, a material collecting disc 72 rotatably mounted on the material collecting frame 71, and a paper placing disc 73 rotatably mounted on the material collecting frame 71. The material collecting frame 71 is further provided with a material collecting motor 74 for driving the material collecting disc 72 to rotate. The material collecting disc 72 and the paper placing disc 73 are both located at the end of the material moving track 221. The projections of the material collecting disc 72, the paper placing disc 73 and the material moving track 221 in the top view direction are on the same straight line. The paper placing disc 73 is wound with a separation paper 75, and the other end of the separation paper 75 is fixed on the material collecting disc 72. The shaped terminal string is pulled from the material moving track 221 to the material collecting disc 72 for fixation, and then the material collecting motor 74 drives the material collecting disc 72 to rotate counterclockwise, so that the terminal string is gradually wound on the material collecting disc 72.
