A third linkage pulley 42344 is also rotatably arranged on the second third-linkage slide bar 42343 in the direction close to the third cam 4223. This third linkage pulley 42344 abuts against the third cam 4223.

[0089] In the embodiment of the present invention, during the rotation of the third cam 4223, the fourth cam 4224, and the fifth cam 4225, they can respectively drive the first second-linkage slide bar 42323, the second linkage slide bar 42331, and the second third-linkage slide bar 42343 to slide. The second linkage pulley 42332 of the second linkage slide bar 42331 directly drives the material pressing part 44 to act. The first second-linkage slide bar 42323 drives the first linkage pulley 42324 on the first linkage slide bar 42322 through the first linkage plate 42321 to drive the flattening part 43 to act. The second third-linkage slide bar 42343 drives the third linkage pulley 42344 on the first third-linkage slide bar 42342 through the third linkage plate 42341 to drive the material pressing part 44 to act. In the embodiment of the present invention, through the third cam 4223, the fourth cam 4224, and the fifth cam 4225 of the driving part 42, they are combined to drive the flattening part 43 and the material pressing part 44 in an integrated linkage manner. Through the integrated material pressing device 4, the first connection end 71 is conveyed onto the integrated material pressing device 4. Similarly, the welding wire is conveyed onto the integrated material pressing device 4. On the integrated material pressing device 4, the welding wire will be flattened and then cut into individual second connection ends 72, and then the second connection ends 72 are crimped onto the first connection end 71. The integrated material pressing device 4 realizes the overall linkage drive through a single driving part 42, with a compact structure, high synchronism, and effectively ensuring the crimping accuracy. Further, in the embodiment of the present invention, the horizontal driving forces of the third cam, the fourth cam, and the fifth cam can be converted into the vertical driving forces of the first linkage slide bar, the second linkage slide bar, and the first third-linkage slide bar.

[0090] As Figure 5 、 10As shown in FIGS. 10 and 11, the driving part 42 further includes a second linkage assembly 424, and the second linkage assembly 424 is disposed above the flattening part 43; the second linkage assembly 424 includes two groups of second linkage brackets 4241 arranged side by side, and the second linkage brackets 4241 are disposed on the mounting table 41. The gap between the two second linkages is the installation position of the first linkage assembly 423, and the structure is compact; a second linkage plate 4242 is rotatably disposed at 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. A first second linkage wheel 42431 is rotatably disposed at the bottom of the linkage rod 4243. The other ends of the two second linkage plates 4242 are connected by a second linkage connecting plate 4244, and a second linkage wheel two 42441 is rotatably disposed below the second linkage connecting plate 4244; the first cam 4221 and the seventh cam 4227 respectively abut against the first second linkage wheel 42431 one by one.

In this embodiment, when the flattening part 43 flattens the welding line, it is necessary to flatten the circular welding line into an elliptical cross-section. After flattening, the cutting knife 435 on the flattening part 43 is used for cutting. After cutting, each second connecting end 72 will fall into the pressing part 44. In order to make the blanking accurate, it is necessary to drive the flattening part 43 to move downward so that the flattening part 43 fits the pressing part 44. In the embodiment of the present invention, the first cam 4221 and the seventh cam 4227 are used to drive the second linkage plate 4242 to swing, and the second linkage plate 4242 can drive the downward pressing flattening part 43 through the second linkage wheel two 42441, so that the flattening part 43 fits the pressing part 44. Since the flattening part 43 is sleeved on the sleeve rod 45 through a spring, when the second linkage plate 4242 is not pressed down, under the action of the spring force, the flattening part 43 returns to its original position. In the embodiment of the present invention, through a single driving part 42, the integrated driving assembly 421 drives the driving main shaft 4211 to rotate, and the driving main shaft 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, realizing an integrated linkage structure of a single drive, saving costs and effectively ensuring the synchronization of each action.

[0092] As Figure 14 and 15 shown, the third linkage assembly 425 further includes a third linkage mounting frame 4255. The third linkage mounting frame 4255 is disposed below the mounting table 41. A third linkage sliding rod 42551 is slidably provided on the third linkage mounting frame 4255. The top of the third linkage sliding rod 42551 passes through the mounting table 41 and is connected to the material pressing part 44. A third linkage clamping block 42552 is further fixedly provided on the third linkage sliding rod 42551. A third linkage clamping groove 425521 is formed on the third linkage clamping block 42552. The linkage clamping column 42531 is snapped into the third linkage clamping groove 425521.

[0093] In the embodiment of the present invention, when the sixth cam 4226 rotates, it drives the first third linkage plate 4252 to rotate. The first third linkage plate 4252 drives the second third linkage plate 4253 to rotate. The second third linkage plate 4253 drives the linkage clamping column 42531 to swing up and down. The linkage clamping column 42531 is snapped into the third linkage clamping groove 425521 of the third linkage clamping block 42552, driving the third linkage sliding rod 42551 to move up and down. The material pressing part 44 is driven to move up and down through the third linkage sliding rod 42551. In the embodiment of the present invention, through a single driving part 42, the integrated driving assembly 421 drives the driving main shaft to rotate. The driving main shaft 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 an integrated linkage structure with a single drive, effectively ensuring the synchronization of the actions of the material pressing part 44 and the flattening part 43.

[0094] As Figure 11 、 16As shown in FIGS. 0 to 19, the flattening portion 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 will not affect the sliding of the first flattening slider 432 within the defined range. The first flattening seat 431 is provided with a first flattening slide rod 4311 in the direction of the first flattening slider 432. A first flattening slide hole 4321 corresponding to the first flattening slider 432 is formed in the first flattening slider 432. A first flattening die 4312 is connected to the first flattening seat 431. A first flattening die 4322 corresponding to the first flattening die 4312 is provided on the first flattening slider 432. A plurality of first flattening grooves 43121 are formed in the first flattening die 4312. A first flattening groove 43221 corresponding to the first flattening groove 43121 is formed in the first flattening die 4322. A wire guide plate 4313 is provided above the first flattening die 4312. A wire hole 43131 is formed in the wire guide plate 4313. The wire 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. A spring is further provided between the first flattening seat 431 and the first flattening slider 432. The flattening portion 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 portion 43. Positioning blocks are also provided on both sides of the second flattening slider 434. It should be noted that the positioning blocks will not affect the sliding of the second flattening slider 434 within the set range. The second flattening seat 433 is provided with a second flattening slide rod 4331 in the direction of the second flattening slider 434. A second flattening slide hole 4341 corresponding to the second flattening slider 434 is formed in the second flattening slider 434. A second flattening die 4332 is connected to the second flattening seat 433. A second flattening die 4342 corresponding to the second flattening die 4332 is provided on the second flattening slider 434. A plurality of second flattening grooves 43321 are formed in the second flattening die. A second flattening groove 43421 corresponding to the second flattening groove 43321 is formed in the second flattening die 4342. 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 knife 435.

[0095] In an embodiment of the present invention, the welding wire enters the first flattening groove 43121 and the second flattening groove 43421 through the wire hole 43131. The fifth cam 4225 drives the first linkage module 4232 to move. The first linkage module 4232 drives the first flattening slider 432 to move towards the first flattening seat 431, so as to first flatten the welding wire in the first flattening groove 43121 and the first flattening groove 43221 for the first time. After the first flattening is completed, when the third cam 4223 continues to rotate and the second cam 4222 does not drive the first flattening slider 432, since a spring is provided 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 downward into the second flattening groove 43321 and the second flattening groove 43421. At this time, the fourth cam 4224 will drive the second linkage assembly 424 to move. The second linkage assembly 424 drives the second flattening slider 434 to move towards the first flattening seat 431, so as to second flatten the welding wire in the second flattening groove 43321 and the second flattening groove 43421. At the same time, the cutting knife 435 at the bottom of the second flattening slider 434 will cut the welding wire into individual second connection ends 72. Since 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, and the welding wire is flattened for the first time, flattened for the second time and cut in this way repeatedly. Further, during cutting, in order to make the second connection ends 72 smoothly fall into the material pressing part 44, the first cam 4221 and the seventh cam 4227 drive the second linkage assembly 424 to act. The second linkage assembly 424 drives the first flattening seat 431 and the second flattening seat 433 to move downward to fit the material pressing part 44.

[0096] As Figure 11 , 20 Shown in FIGS. 24 to 25, the material pressing part 44 includes a material pressing fixed component 441 and a material pressing movable component 442. The material pressing movable component 442 is located above the material pressing fixed component 441. The material pressing movable component 442 is sleeved on the sleeve rod 45, and a spring is provided between the material pressing movable component 442 and the sleeve rod 45. The material pressing fixed component 441 is arranged on the mounting table 41. The sleeve rod 45 passes through the material pressing fixed component 441. The third linkage slide rod 42551 passes through the material pressing fixed component 441 to connect the material pressing movable component 442.

[0097] As Figures 22 to 24As shown, the blank holding and fixing assembly 441 includes a blank holding and fixing base 4411, a blank holding mounting seat 4412, and a blank holding cover plate 4413. A blank holding mounting groove 44111 and a blank holding step 44112 are formed on the blank holding and fixing base 4411. An L-shaped linkage block 4414 is rotatably arranged in the blank holding mounting groove 44111. One end of the L-shaped linkage block 4414 is rotatably provided with a blank holding abutting wheel 44141. A spring is arranged at the bottom of the L-shaped linkage block 4414. The other end of the L-shaped linkage block 4414 is provided with a plurality of blank holding ejector pins 44142. A first blank holding spring 441421 is sleeved on the blank holding ejector pin 44142. The blank holding mounting seat 4412 is arranged on the blank holding step 44112. A blank holding conveying channel 44121, a plurality of blank holding fixing platforms 44122, and a blank holding fixing and discharging inclined surface 44123 are arranged on the blank holding mounting seat 4412. The conveying device 3 conveys the first connection end 71 to the blank holding conveying channel 44121. A blank holding fixing hole 441221 is formed in the blank holding fixing platform 44122. The blank holding ejector pin 44142 passes through the blank holding fixing hole 441221. The top of the first blank holding spring 441421 abuts against the lower part of the blank holding fixing hole 441221. The blank holding cover plate 4413 is arranged above the blank holding mounting seat 4412. A blank holding avoidance groove 44131 is formed in the blank holding cover plate 4413. The blank holding avoidance groove 44131 is located above the blank holding fixing platform 44122.

[0098] As 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. The pressing movable seat 4421 is provided with a pressing movable slide rod 44211 in the direction of 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 slide hole 44221 corresponding to the pressing movable slider 4422 is formed in the pressing movable slider 4422. A first pressing movable die 44212 is connected to the pressing movable seat 4421. A pressing positioning through groove 442121 is provided on the first pressing movable die 44212. A second pressing movable die 44222 corresponding to the first pressing movable die 44212 is provided on the pressing movable slider 4422. A number of pressing movable pressing blocks 442122 are provided at the bottom of the first pressing movable die 44212. The pressing movable pressing blocks 442122 are located below the pressing positioning through groove 442121. A pressing nozzle 442221 corresponding to the pressing movable pressing blocks 442122 is provided at the bottom of the second pressing movable die 44222.

[0099] In the embodiment of the present invention, when the second connection end 72 cut out falls into the pressing positioning through groove 442121 when the flattened portion 43 approaches the pressing portion 44, after being positioned by the pressing positioning through groove 442121, as Figure 25 shown, it falls onto the clamping mouth of the auxiliary sheet 8. At the same time, driven by the second cam 4222, the pressing movable seat 4421 is driven to move downward by the third linkage slide rod 42551. When the pressing movable seat 4421 moves downward, the pressing movable pressing blocks 442122 can just press the first connection end 71 against the pressing conveying channel 44121. At the same time, when the pressing movable seat 4421 moves downward, the bottom of the pressing movable seat 4421 will abut against the pressing abutting wheel 44141, causing the L-shaped linkage block 4414 to swing, so that the pressing ejector pin 44142 moves upward through the pressing fixing hole 441221. There are three groups of pressing ejector pins 44142. The tops of the corresponding pressing ejector pins 44142 will pass through the auxiliary moving holes 81 of the auxiliary sheet 8, so that the auxiliary sheet 8 is fixed by the pressing ejector pins 44142. Then, driven by the third cam 4223, the third linkage module 4234 drives the pressing movable slider 4422 to move towards the pressing movable seat 4421. The pressing nozzle 442221 at the bottom of the pressing movable slider 4422 just pushes the second connection end 72 located on the clamping mouth of the auxiliary sheet 8 into the clamping mouth of the first connection end 71, so that the second connection end 72 is crimped on the first connection end 71, completing the entire pressing process. After the crimping is completed, it is reset under the action of the elastic force, and such reciprocating cyclic actions are performed. AsFigure 5 As shown, a detection component 61 can also be provided on the mounting table 41 to detect whether the pin 7 is qualified. The detection component 61 is not the main innovation point and will not be elaborated here.

[0100] Such as Figure 5 、 6As shown in FIGS. 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 arranged below the mounting table 41. A conveying linkage rod 314 is rotatably arranged 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. 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. The conveying linkage rod 314 drives the second conveying linkage plate 313 to swing. The conveying fixing part 32 includes a conveying fixing base 321. A fixed conveying channel 3211 is arranged on the conveying fixing base 321. The first connection end 71 and the auxiliary piece 8 are conveyed on the fixed conveying channel 3211. A pushing slider 322 is slidably arranged on the conveying fixing base 321. A pushing connection block 323 is arranged on the pushing slider 322. A pushing needle 324 is arranged below the pushing connection block 323. A stop block 325 is arranged on one side of the pushing needle 324 for restricting the rotation of the pushing needle 324. A pushing spring 326 is arranged between the pushing connection block 323 and the pushing slider 322. The pushing connection block 323 can slide up and down relative to the pushing slider 322. The pushing needle 324 is inserted into the fixed conveying channel 3211. The other end of the second conveying linkage plate 313 is rotatably provided with a pushing linkage wheel 315. The pushing linkage wheel 315 is connected to the pushing slider. In the embodiment of the present invention, the second conveying linkage plate 313 swings to drive the pushing linkage wheel 315 to swing. The pushing linkage wheel 315 can drive the pushing slider 322 to slide on the conveying and pushing fixing seat. When the pushing slider moves towards the flattening part, the pushing slider drives the pushing connection block 323 to move. The pushing needle 324 below the pushing connection 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 pushing needle 324, the pushing needle 324 cannot rotate. Therefore, the pushing needle 324 can push the auxiliary piece 8 and the first connection end 71 to move. When the pushing slider retracts, there is no stop block 325 on the other side of the pushing needle 324. Therefore, the pushing needle 324 can rotate and retract to the rear side. Combined with the downward pressure of the elastic force of the pushing spring 326, the pushing needle 324 is inserted into the next auxiliary moving hole 81 again. In this way, the first connection end 71 and the auxiliary piece 8 are conveyed in a reciprocating cycle.

[0101] As Figure 5 , 6As shown in FIGS. 28 to 30, the first connection end 71 and the auxiliary piece 8 are fixedly connected together. Eventually, it is necessary to separate the first connection end 71 and the auxiliary piece 8. By bending the first connection end 71 and the auxiliary piece 8, it is convenient for the subsequent separation of the first connection end 71 and the auxiliary piece 8. A bending portion 5 is further provided on the mounting table 41, and the bending portion 5 is provided between the conveying device 3 and the integral pressing device 4. The driving portion 42 further includes a fourth linkage assembly 426. The bending portion 5 includes a bending base 51, a bending cover plate 52, and a bending pressing block 53. A bending conveying channel 511 is provided on the bending base 51. A first bending avoidance groove 521 is provided on the bending cover plate 52. The bending pressing block 53 is disposed above the bending cover plate 52. A bending slide rod 531 is connected below the bending pressing block 53. The bending slide rod 531 passes through the bending base 51 and the mounting table 41. A bending pressing knife 532 is provided below the bending pressing block 53, and the bending pressing knife 532 can be inserted into the first bending avoidance groove 521. A bending fixing rod 512 is provided on the bending base 51, and a spring is sleeved on the bending fixing rod 512. The bending pressing block 53 is sleeved on the bending fixing rod 512. In the embodiment of the present invention, the fourth linkage assembly 426 drives the bending slide rod 531 to move downward, so that the bending pressing block 53 moves downward, and the bending pressing knife 532 of the bending pressing block 53 is inserted into the first bending avoidance groove 521. The bending pressing knife 532 bends the connection position between the first connection end 71 and the auxiliary piece 8. It should be noted that this bending does not completely separate the connection between the first connection end 71 and the auxiliary piece 8. The first connection end 71 and the auxiliary piece 8 are still in a connected state. This bending only makes it easier for the auxiliary piece 8 to be separated from the first connection end 71 after the subsequent pressing is completed. It should be noted that why not bend after the second connection end 72 is pressed onto the second connection end 72, because the connection position between the first connection end 71 and the auxiliary piece 8 is exactly the position where the second connection end 72 is pressed onto the first connection end 71. If the bending is carried out after the pressing is completed, the already completed pressing of the first connection end 71 and the second connection end 72 will be damaged. Through this bending, only by gently pulling the auxiliary piece 8 subsequently, the first connection end 71 and the auxiliary piece 8 can be separated. A second bending avoidance groove 513 is further provided on the bending base 51. A CCD detection mechanism 62 can also be provided on the mounting table 41. The CCD detection mechanism 62 detects whether the first connection end 71 conveyed to the flattening portion 43 through the second bending avoidance groove 513 is a qualified first connection end 71.

[0102] As Figure 5 、 6As shown in FIGS. 27 and 28, the fourth linkage assembly 426 includes a fourth linkage fixing bracket 4261, on which a fourth linkage plate 4262 is rotatably provided. One end of the fourth linkage plate 4262 is provided with a fourth linkage rod 42621, and at the top of the fourth linkage rod 42621, a fourth linkage wheel 426211 is rotatably provided. Corresponding holes are formed in the mounting table 41, and the fourth linkage wheel 426211 passes through the corresponding holes in the mounting table 41. The second cam 4222 abuts against the fourth linkage wheel 426211. The other end of the fourth linkage plate 4262 is connected with a fourth linkage mounting block 4263, and the bottom of the bent sliding rod 531 is connected with the fourth linkage mounting block 4263. In this embodiment, the structure is similar to that of the third linkage assembly 425. The second cam 4222 of the driving part 42 drives the fourth linkage plate 4262 to swing. The fourth linkage plate 4262 includes a first fourth linkage plate and a second fourth linkage plate, which are rotatably connected. There is enough space on the fourth linkage fixing bracket 4261 for the first fourth linkage plate and the second fourth linkage plate to swing. The second fourth linkage plate drives the fourth linkage mounting block 4263 to move downward, thereby driving the bent pressing block 53 to move downward. In the embodiment of the present invention, the driving part 42 is integrally driven to drive the bending part 5, so that each action is synchronously linked. In the 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 driving part 42 are all driven by the same drive linkage, and each completes its own action. At the same time, the actions are combined to complete bending, flattening, cutting and material pressing in a linked manner.
