[0062] In this embodiment of the present invention, the third cam 4223, the fourth cam 4224, and the fifth cam 4225 can respectively drive the first linkage slide rod 42323, the second linkage slide rod 42331, and the third linkage slide rod 42343 to slide during rotation. The second linkage pulley 42332 of the second linkage slide rod 42331 directly drives the pressing part 44 to move. The first linkage slide rod 42323 drives the first linkage pulley 42324 on the first linkage slide rod 42322 to move the flattening part 43 through the first linkage plate 42321. The third linkage slide rod 42343 drives the third linkage pulley 42344 on the third linkage slide rod 42342 to move the pressing part 44 through the third linkage plate 42341. In this embodiment of the invention, the third cam 4223, the fourth cam 4224, and the fifth cam 4225 of the drive unit 42 are combined to drive the flattening unit 43 and the pressing unit 44 in a coordinated manner. The first connecting end 71 is fed to the pin-integrated pressing device 4, and the welding wire is similarly fed to the pin-integrated pressing device 4. The welding wire is flattened and cut into individual second connecting ends 72 on the pin-integrated pressing device 4, and then the second connecting ends 72 are pressed onto the first connecting end 71. The pin-integrated pressing device 4 achieves overall coordinated driving through a single drive unit 42, resulting in a compact structure, high synchronization, and effectively ensuring the accuracy of the pressing. Furthermore, in this embodiment of the invention, the horizontal driving force of the third, fourth, and fifth cams can be converted into the vertical driving force of the first, second, and third linkage slide rods.

[0063] like Figure 5 , 10As shown in Figure 11, the driving unit 42 further includes a second linkage assembly 424, which is disposed above the flattened part 43. The second linkage assembly 424 includes two sets of second linkage brackets 4241 arranged side by side. The second linkage brackets 4241 are disposed on the mounting platform 41, and the gap between the two second linkages is the installation position of the first linkage assembly 423, resulting in a compact structure. A second linkage plate 4242 is rotatably disposed on the top of the second linkage bracket 4241, and a second linkage rod 4243 is disposed at one end of the second linkage plate 4242. The bottom is rotatably provided with a second linkage wheel 42431, and the other ends of the two sets of second linkage plates 4242 are connected by a second linkage connecting plate 4244.

The second linkage wheel 42441 is engaged in the hook arc groove 42451. In this embodiment, the flattening part 43 flattens the welding line, which needs to flatten the circular welding line into an elliptical cross-section. After flattening, it is cut by the cutting blade 435 on the flattening part 43. After cutting, each second connecting end 72 will fall into the pressing part 44. In order to ensure accurate material dropping, the flattening part 43 needs to be driven to move downward so that the flattening part 43 fits into the pressing part 44. In this embodiment of the present invention, the second linkage plate 4242 is driven to swing by the first cam 4221 and the seventh cam 4227. The second linkage plate 4242 can drive the flattening part 43 to press down through the second linkage wheel 42441 so that the flattening part 43 fits into the pressing part 44. Since the flattening part 43 is spring-sleeved on the sleeve rod 45, when the second linkage plate 4242 is not pressed down, the flattening part 43 returns to its original position under the action of the spring force. In this embodiment of the utility model, a single drive unit 42 drives the drive spindle 4211 to rotate, and the drive spindle 4211 drives the first cam 4221, the third cam 4223, the fourth cam 4224, the fifth cam 4225 and the seventh cam 4227 to rotate, thereby realizing a single-drive integrated linkage structure, saving costs and effectively ensuring the synchronization of each action.

The linkage pin 42531 is inserted into the third linkage slot 425521.

[0066] In this embodiment of the invention, the sixth cam 4226 rotates, driving the third linkage plate 1 4252 to rotate. The third linkage plate 1 4252 drives the third linkage plate 2 4253 to rotate. The third linkage plate 2 4253 drives the linkage pin 42531 to swing up and down. The linkage pin 42531 engages with the third linkage slot 425521 of the third linkage block 42552, driving the third linkage slide rod 42551 to move up and down. The third linkage slide rod 42551 drives the pressing part 44 to move up and down. In this embodiment of the invention, a single drive unit 42 and an integrated drive assembly 421 drive the drive spindle to rotate. The drive spindle drives the first cam 4221, the third cam 4223, the fourth cam 4224, the fifth cam 4225, the sixth cam 4226, and the seventh cam 4227 to rotate, realizing a single-drive integrated linkage structure, effectively ensuring the synchronicity of the actions of the pressing part 44 and the flattening part 43.

[0067] like Figure 11 , 16As shown in Figure 19, the flattening part 43 includes a first flattening seat 431 and a first flattening slider 432. Positioning blocks are provided on both sides of the first flattening slider 432. It should be noted that the positioning blocks do not affect the sliding of the first flattening slider 432 within a limited range. A first flattening slide rod 4311 is provided on the first flattening seat 431 towards the first flattening slider 432. A first flattening slide hole 4321 corresponding to the first flattening slider 432 is provided on the first flattening seat 431. A first flattening mold 4312 is connected to the first flattening seat 431, and a first flattening mold corresponding to the first flattening mold 4312 is provided on the first flattening slider 432. 4322, the first flattening mold 4312 has a plurality of first flattening grooves 43121, the second flattening mold 4322 has a first flattening groove 43221 corresponding to the first flattening grooves 43121, a guide plate 4313 is provided above the first flattening mold 4312, the guide plate 4313 has a guide hole 43131, the guide hole 43131 corresponds to the first flattening groove 43121; one end of the first linkage module 4232 abuts against the side of the first flattening slider 432 away from the first flattening seat 431, and a spring is also provided between the first flattening seat 431 and the first flattening slider 432. The flattening part 43 further includes a second flattening seat 433 and a second flattening slider 434. The second flattening seat 433 is connected below the first flattening part 43. Positioning blocks are also provided on both sides of the second flattening slider 434. It should be noted that the positioning blocks do not affect the sliding of the second flattening slider 434 within a set range. A second flattening slide rod 4331 is provided on the second flattening seat 433 towards the second flattening slider 434. A second flattening slide hole 4341 corresponding to the second flattening slider 434 is provided on the second flattening seat 433. A second flattening mold 4332 is connected to the second flattening seat 433. The second flattening slider 434 is provided with a second flattening mold 4342 corresponding to the second flattening mold 4332. The second flattening mold is provided with a plurality of second flattening grooves 43321. The second flattening mold is provided with a second flattening groove 43421 corresponding to the first second flattening groove 43321. One end of the second linkage module 4233 abuts against the side of the second flattening slider 434 away from the second flattening seat 433. A spring is provided between the second flattening seat 433 and the second flattening groove. The bottom of the second flattening groove 43421 is connected to the cutting blade 435.

[0068] In this embodiment of the invention, the welding wire enters the first flattening groove 43121 and the second flattening groove 43421 from the wire hole 43131. The fifth cam 4225 drives the first linkage module 4232 to move, and the first linkage module 4232 drives the first flattening slider 432 to move towards the first flattening seat 431, so that the welding wire is flattened for the first time in the first flattening groove 43121 and the first flattening groove 43221. After the first flattening is completed, the third cam 4223 continues to rotate. When the second cam 4222 does not drive the first flattening slider 432, since there is a spring between the first flattening slider 432 and the first flattening seat 431, the first flattening slider 432 will move away from the first flattening seat 431. At this time, the welding wire will continue to move towards the first flattening seat 431. The wire moves down into the second flattening groove 43321 and the second flattening groove 43421. At this time, the fourth cam 4224 will drive the second linkage component 424 to move. The second linkage component 424 will drive the second flattening slider 434 to move towards the first flattening seat 431, so as to realize the second flattening of the welding wire in the second flattening groove 43321 and the second flattening groove 43421. At the same time, the cutting blade 435 at the bottom of the second flattening slider 434 will cut the welding wire into individual second connecting ends 72. A spring is provided between the second flattening seat 433 and the second flattening slider 434. The second flattening slider 434 will move away from the first flattening seat 431. The welding wire is flattened, flattened, and cut repeatedly. Furthermore, during the cutting process, in order to ensure that the second connecting end 72 falls smoothly into the pressing part 44, the first cam 4221 and the seventh cam 4227 drive the second linkage component 424 to move. The second linkage component 424 drives the first flattening seat 431 and the second flattening seat 433 to move downward and fit against the pressing part 44.

[0069] like Figure 11 , 20 As shown in Figure 25, the pressing part 44 includes a pressing fixing component 441 and a pressing movable component 442. The pressing movable component 442 is located above the pressing fixing component 441. The pressing movable component 442 is sleeved on the sleeve rod 45, and a spring is provided between the pressing movable component 442 and the sleeve rod 45. The pressing fixing component 441 is disposed on the mounting platform 41. The sleeve rod 45 passes through the pressing fixing component 441. The third linkage slide rod 42551 passes through the pressing fixing component 441 and connects to the pressing movable component 442.

[0070] like Figures 22 to 24As shown, the pressing and fixing assembly 441 includes a pressing and fixing base 4411, a pressing and fixing mounting seat 4412, and a pressing and fixing cover plate 4413. The pressing and fixing base 4411 has a pressing and fixing groove 44111 and a pressing and fixing step 44112. An L-shaped linkage block 4414 is rotatably mounted on the pressing and fixing groove 44111. A pressing and fixing abutment wheel 44141 is rotatably mounted at one end of the L-shaped linkage block 4414. A spring is mounted at the bottom of the L-shaped linkage block 4414, and several pressing and fixing top posts 44142 are mounted at the other end of the L-shaped linkage block 44142. A first pressing and fixing spring 441421 is sleeved on each pressing and fixing top post 44142. The pressing and fixing seat 4412 is mounted on the pressing and fixing step 44112. The 412 is provided with a pressing conveying channel 44121, a plurality of pressing fixing platforms 44122 and a pressing fixing unloading inclined surface 44123. The conveying device 3 conveys the first connecting end 71 to the pressing conveying channel 44121. The pressing fixing platform 44122 is provided with a pressing fixing hole 441221. The pressing top column 44142 passes through the pressing fixing hole 441221. The top of the first pressing spring 441421 abuts against the bottom of the pressing fixing hole 441221. The pressing cover plate 4413 is provided above the pressing mounting base 4412. The pressing cover plate 4413 is provided with a pressing relief groove 44131. The pressing relief groove 44131 is located above the pressing fixing platform 44122.

[0071] like Figure 20 and 21As shown, the pressing movable assembly 442 includes a pressing movable seat 4421 and a pressing movable slider 4422. Positioning blocks are provided on both sides of the pressing movable slider 4422. It should be noted that the positioning blocks do not restrict the sliding of the pressing movable slider 4422. A pressing movable slide rod 44211 is provided on the pressing movable seat 4421 towards the pressing movable slider 4422. A spring is also provided between the pressing movable seat 4421 and the pressing movable slider 4422. A pressing movable sliding hole 44221 corresponding to the pressing movable slider 4422 is provided on the pressing movable seat 4421. A first pressing movable mold 44212 is connected to the upper part of the material. The first pressing movable mold 44212 is provided with a pressing positioning groove 442121. The pressing movable slider 4422 is provided with a second pressing movable mold 44222 corresponding to the first pressing movable mold 44212. The bottom of the first pressing movable mold 44212 is provided with a plurality of pressing movable clamping blocks 442122. The pressing movable clamping blocks 442122 are located below the pressing positioning groove 442121. The bottom of the second pressing movable mold 44222 is provided with a pressing push nozzle 442221 corresponding to the pressing movable clamping block 442122.

[0072] In this embodiment of the present invention, when the cut-out second connecting end 72 is close to the pressing part 44 on the flattened part 43, the second connecting end 72 falls into the pressing positioning groove 442121. After being positioned by the pressing positioning groove 442121, as... Figure 25 As shown, the material falls into the clamping jaws of the auxiliary piece 8. Simultaneously, driven by the second cam 4222, the third linkage slide rod 42551 drives the pressing movable seat 4421 to move downward. When the pressing movable seat 4421 moves downward, the pressing movable clamping block 442122 can press the first connecting end 71 onto the pressing conveying channel 44121. At the same time, as the pressing movable seat 4421 moves downward, the bottom of the pressing movable seat 4421 abuts against the pressing abutment wheel 44141, causing the L-shaped linkage block 4414 to swing, thereby causing the pressing top column 44142 to move upward and pass through the pressing fixing hole 441221. Three sets of pressure pins 44142 are provided. The tops of the corresponding pressure pins 44142 pass through the auxiliary moving holes 81 of the auxiliary piece 8, fixing the auxiliary piece 8 to the pressure pins 44142. Then, driven by the third cam 4223, the third linkage module 4234 drives the pressure sliding block 4422 to move towards the pressure seat 4421. The pressure push nozzle 442221 at the bottom of the pressure sliding block 4422 pushes the second connecting end 72, located on the clamping jaw of the auxiliary piece 8, into the clamping jaw of the first connecting end 71, pressing the second connecting end 72 against the first connecting end 71, completing the entire pressure process. After pressing, it resets under the action of elasticity, and this cycle repeats. Figure 5 As shown, a detection component 61 can also be set on the mounting platform 41 to detect whether the completed pin 7 is qualified. The detection component 61 is not a major innovation and will not be elaborated here.

[0073] like Figure 5 , 6As shown in Figures 26 and 27, the conveying device 3 includes a conveying drive assembly 31 and a conveying fixing part 32; the conveying drive assembly 31 includes a conveying drive cylinder 316, a conveying mounting block 311, a first conveying linkage plate 312, and a second conveying linkage plate 313. The conveying drive cylinder 316 is disposed below the mounting platform 41. A conveying linkage rod 314 is rotatably disposed on the conveying mounting block 311. The bottom of the conveying linkage rod 314 is connected to one end of the first conveying linkage plate 312, the output end of the conveying drive cylinder 316 is connected to the other end of the first conveying linkage plate 312, and the top of the conveying linkage rod 314 is connected to one end of the second conveying linkage plate 313. The conveying drive cylinder 316 drives the first conveying linkage plate 312 to swing, the first conveying linkage plate 312 drives the conveying linkage rod 314 to rotate, and the conveying linkage rod 314 drives the second conveying linkage plate 313 to swing; the conveying... The fixing part 32 includes a conveying fixing base 321, on which a fixed conveying channel 3211 is provided. The first connecting end 71 and the auxiliary piece 8 are conveyed on the fixed conveying channel 3211. A pusher slider 322 is also slidably provided on the conveying fixing base 321. A pusher connecting block 323 is provided on the pusher slider 322. A pusher needle 324 is provided below the pusher connecting block 323. A stop block 325 is provided on one side of the pusher needle 324 to restrict the rotation of the pusher needle 324. A pusher spring 326 is provided between the pusher connecting block 323 and the pusher slider 322. The pusher connecting block 323 can slide up and down relative to the pusher slider 322. The pusher needle 324 is engaged in the fixed conveying channel 3211. A pusher linkage wheel 315 is rotatably provided at the other end of the second conveying linkage plate 313. The pusher linkage wheel 315 is connected to the pusher slider. In this embodiment of the utility model, the second conveying linkage plate 313 swings to drive the pusher linkage wheel 315 to swing. The pusher linkage wheel 315 can drive the pusher slider 322 to slide on the conveying pusher fixed seat. When the pusher slider moves towards the flattened part, the pusher slider drives the pusher connecting block 323 to move. The pusher needle 324 below the pusher connecting block 323 is inserted into the auxiliary moving hole 81 of the auxiliary piece 8. Due to the blocking effect of the stop block 325 on one side of the pusher needle 324, the pusher needle 324 cannot rotate. Therefore, the pusher needle 324 can push the auxiliary piece 8 and the first connecting end 71 to move. When the pusher slider retracts, there is no stop block 325 on the other side of the pusher needle 324. Therefore, the pusher needle 324 can rotate and retract to the rear side. Combined with the downward pressure of the pusher spring 326, the pusher needle 324 is inserted into the next auxiliary moving hole 81. The first connecting end 71 and the auxiliary piece 8 are conveyed in this way in a reciprocating cycle.

[0074] like Figure 5 , 6As shown in Figures 28 to 30, the first connecting end 71 and the auxiliary piece 8 are fixedly connected together. Ultimately, the first connecting end 71 and the auxiliary piece 8 need to be separated. Bending the first connecting end 71 and the auxiliary piece 8 facilitates their subsequent separation. The mounting platform 41 is also provided with a bending section 5, which is located between the conveying device 3 and the integrated pin pressing device 4. The driving unit 42 also includes a fourth linkage assembly 426. The bending section 5 includes a bending base 51, a bending cover plate 52, and a bending pressing block 53. A bending conveyor is provided on the bending base 51. The channel 511 has a first bending clearance groove 521 on the bending cover plate 52. The bending pressure block 53 is located above the bending cover plate 52. A bending slide rod 531 is connected below the bending pressure block 53. The bending slide rod 531 passes through the bending base 51 and the mounting platform 41. A bending pressure knife 532 is located below the bending pressure block 53. The bending pressure knife 532 can be engaged in the first bending clearance groove 521. A bending fixing rod 512 is provided on the bending base 51. A spring is sleeved on the bending fixing rod 512. The bending pressure block 53 is sleeved on the bending fixing rod 512. In this embodiment of the invention, the fourth linkage component 426 moves the bending slide bar 531 downward, causing the bending pressure block 53 to move downward. The bending pressure blade 532 of the bending pressure block 53 engages with the first bending clearance groove 521. The bending pressure blade 532 bends the connection position between the first connecting end 71 and the auxiliary piece 8. It should be noted that this bending does not completely detach the connection between the first connecting end 71 and the auxiliary piece 8; they remain connected. This bending merely makes it easier for the auxiliary piece 8 to separate from the first connecting end 71 after subsequent crimping. It should be noted that the bending is performed before the second connecting end 72 is crimped onto the first connecting end 71. The connection position between the first connecting end 71 and the auxiliary piece 8 is precisely the position where the second connecting end 72 is crimped onto the first connecting end 71. If the bending is performed after the crimping is completed, the already crimped first connecting end 71 and the second connecting end 72 will be damaged. Through this bending, the first connecting end 71 and the auxiliary piece 8 can be separated by gently pulling the auxiliary piece 8. The bending base 51 is also provided with a second bending clearance groove 513, and the mounting platform 41 can also be provided with a CCD detection mechanism 62. The CCD detection mechanism 62 detects from the second bending clearance groove 513 whether the first connecting end 71 delivered to the flattening part 43 is a qualified first connecting end 71.

[0075] like Figure 5 , 6As shown in Figure 28, the fourth linkage assembly 426 includes a fourth linkage fixing frame 4261, a fourth linkage plate 4262 rotatably mounted on the fourth linkage fixing frame 4261, a fourth linkage rod 42621 at one end of the fourth linkage plate 4262, a fourth linkage wheel 426211 rotatably mounted on the top of the fourth linkage rod 42621, a corresponding hole on the mounting platform 41, the fourth linkage wheel 426211 passing through the corresponding hole on the mounting platform 41, the second cam 4222 abutting against the fourth linkage wheel 426211, a fourth linkage mounting block 4263 connected to the other end of the fourth linkage plate 4262, and the bottom of the bent slide rod 531 connected to the fourth linkage mounting block 4263. Similar to the structure of the third linkage component 425 in this embodiment, the fourth linkage plate 4262 is driven to swing by the second cam 4222 of the drive unit 42. The fourth linkage plate 4262 includes a fourth linkage plate one and a fourth linkage plate two, which are rotatably connected. There is sufficient space on the fourth linkage fixing frame 4261 to allow the fourth linkage plate one and the fourth linkage plate two to swing. The fourth linkage plate two drives the fourth linkage mounting block 4263 to move downward, thereby driving the bending pressure block 53 to move downward. In this embodiment of the present invention, the bending bending part 5 is driven by the integrated drive of the drive unit 42, so that the various actions are synchronized. In this embodiment of the present invention, the first cam 4221, the second cam 4222, the third cam 4223, the fourth cam 4224, the fifth cam 4225, the sixth cam 4226, and the seventh cam 4227 of the drive unit 42 are all driven by the same linkage, each completing its own action. At the same time, the actions are combined and linked to complete the bending, flattening, cutting, and pressing.
