Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0026] Embodiment 1:

[0027] A patch lead processing device includes a workbench 1. On the tabletop of the workbench 1, a positioning and conveying mechanism 2, a pressing roller 3, a moving mechanism 4, a hammering mechanism 6, and a baffle 7 are sequentially arranged from left to right. The positioning and conveying mechanism 2 realizes the positioning and conveying of the lead, ensuring the accuracy of the center position during the lead conveying process. The pressing roller 3 is used to ensure that the lead is conveyed along the tabletop of the workbench 1;

[0028] A cutting mechanism 5 is arranged on the moving mechanism 4, and the moving mechanism 4 is used to drive the cutting mechanism 5 to move left and right. The cutting mechanism 5 is used for cutting the lead;

[0029] The hammering mechanism 6 is arranged on the upper part of the baffle 7, and the hammering mechanism 6 is used for hammering the end of the lead. The baffle 7 is used for limiting the lead.

[0030] The positioning and conveying mechanism 2 includes side plates 201, a first servo motor 202, a first conveying roller 203, a first gear disk 204, a second conveying roller 205, and a second gear disk 206. The first servo motor 202 is arranged outside the side plates 201, and the output end of the first servo motor 202 is fixedly connected to the connection end of one end of the first conveying roller 203 through a coupling. A first gear disk 204 is fixedly installed on the connection end of one end of the first conveying roller 203. The first gear disk 204 is meshed and connected with a second gear disk 206 arranged at the connection end of one end of the second conveying roller 205. The second conveying roller 205 is arranged above the first conveying roller 203.

[0031] The positioning and conveying mechanism 2 further includes a worm 207, a rocker 208, a mounting seat 209, a worm gear 210, a positive and negative lead screw 211, a slider 212, a guide roller 213 and a first slide bar 214. The two ends of the worm 207 are rotatably connected to the inside of the side plate 201, and one end of the worm 207 is fixedly installed with a worm gear 210. The worm gear 210 is in transmission connection with the worm 207 at the bottom. One end of the worm 207 is fixedly installed with a rocker 208, and the two ends of the worm 207 are rotatably installed on the mounting seat 209. The sliders 212 are symmetrically arranged at both ends of the positive and negative lead screw 211, and the inner bottom end of the slider 212 is slidably connected to the first slide bar 214 arranged at the bottom of the positive and negative lead screw 211. Scale lines are arranged on the first slide bar 214. The guide roller 213 is arranged on the slider 212 and is used for positioning the width of the lead wire.

[0032] By arranging the positioning and conveying mechanism 2 and the pressure roller 3 at the front end of the table surface of the workbench 1, precise positioning and conveying of the lead wire are realized, so as to ensure precise hammering and cutting of the end of the lead wire. By the action of the first servo motor 202, the first gear disk 204 and the second gear disk 206, relative rotation of the first conveying roller 203 and the second conveying roller 205 is realized, and the lead wire between the two conveying rollers is conveyed forward. By using the guide rollers 213 on both sides at the front end of the conveying roller, the width of the lead wire is limited, ensuring that the lead wire is always conveyed at the center of the conveying roller, so as to ensure that the lead wire is at the center of the bottom of the cutting mechanism 5 and the hammering mechanism 6 during the conveying process, improving the conveying effect. By rotating the rocker 208, the rotation of the positive and negative lead screw 211 is realized, and thus the guide rollers 213 are driven by the two sliders 212 to approach or move away from each other, and the distance between the two guide rollers 213 is adjusted to adapt to the conveying of lead wires of different widths.

[0033] The moving mechanism 4 includes a support frame 401, a second servo motor 402, a screw rod 403, a sliding seat 404 and a second slide bar 405. The support frame 401 is arranged on one side of the workbench 1, and a second servo motor 402 is arranged on the support frame 401. The output end of the second servo motor 402 is fixedly connected to one end of the screw rod 403 through a coupling. The screw rod 403 is in threaded connection with the inner side of one side of the sliding seat 404. The inner side of the other side of the sliding seat 404 is slidably connected to the second slide bar 405 arranged on one side of the screw rod 403.

[0034] A cutting mechanism 5 is arranged at the center of the sliding seat 404. The cutting mechanism 5 includes a first telescopic rod 501, a first mounting plate 502 and a cutting knife 503. The first telescopic rod 501 is arranged at the center of the sliding seat 404, and the output end of the first telescopic rod 501 is fixedly connected to the center of the first mounting plate 502. A cutting knife 503 is arranged at the bottom of the first mounting plate 502.

[0035] By arranging the truncating mechanism 5 on the moving mechanism 4, the moving mechanism 4 drives the truncating mechanism 5 to move left and right, so as to adjust the position of the lead cutting.

[0036] The hammering mechanism 6 includes a second telescopic rod 601, a second mounting plate 602 and a hammer head 603. The second telescopic rod 601 is arranged on the support frame 401, and the output end of the second telescopic rod 601 is fixedly connected to the center of the second mounting plate 602. A hammer head 603 is arranged at the bottom of the second mounting plate 602, and the hammer head 603 is arranged on the upper part of one side of the baffle 7.

[0037] The hammering mechanism 6 further includes a pressing plate 604, a sliding column 605 and a spring 606. The sliding column 605 is slidably connected to the center of the inside of one side of the second mounting plate 602, and a pressing plate 604 is arranged at the bottom end of the sliding column 605. The spring 606 is sleeved on the outside of the sliding column 605.

[0038] By arranging the hammering mechanism 6 on the upper part of one side of the baffle 7, the end of the lead is held and hammered, ensuring the stability of the lead during the hammering process, thereby ensuring the hammering effect. The driving of the second telescopic rod 601 pushes the second mounting plate 602 to move downward, so that the pressing plate 604 first contacts the lead and presses the lead. As the second mounting plate 602 moves downward and the hammer head 603 falls, the second mounting plate 602 moves downward along the sliding column 605 and compresses the spring 606, realizing the hammer head 603 falling to hammer the end of the lead.

[0039] Working principle: First, adjust the distance between the two guide rollers 213 according to the width of the lead, so that both sides of the lead are along the guide rollers 213 and pass through between the first conveying roller 203 and the second conveying roller 205, then pass through the bottom of the pressing roller 3 and fit with the table top of the workbench 1. With the driving of the first servo motor 202, the two conveying rollers rotate relatively to realize the forward conveying of the lead between them until the end of the lead contacts the baffle 7. Then drive the second telescopic rod 601 to make the pressing plate 604 first press the lead and then hammer the end of the lead through the hammer head 603 (it should be noted that an elastic pad is arranged on the bottom surface of the pressing plate 604, so that the pressing will not damage the lead). After the hammering is completed, drive the first telescopic rod 501, and use the falling of the cutting knife 503 to cut the lead.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
