[0018] Compared with the prior art, the present application has the following beneficial effects: 1. The present application, the device realizes all-around clamping and limiting of the winding drum through the combination structure of the main limiting plate and the auxiliary limiting plate: the main limiting plate serves as the core limiting component and mainly positions the middle part of the winding drum, the auxiliary limiting plates rotatably arranged at both ends of the main limiting plate can adjust the angle through the forward and reverse motor, adapt to winding drums of different diameters, ensure that the winding drum is stably positioned, and avoid shifting; at the same time, the limiting chains on the inner sides of the main limiting plate and the auxiliary limiting plate are rotatably connected through the round rod and form flexible contact with the surface of the winding drum, which not only reduces surface damage caused by rigid extrusion, but also can keep the winding drum in a stable posture during the welding process through the transmission of the chain, and this cooperative structure solves the problems of easy displacement and easy damage of the traditional rigid limiting, so that the positioning error of the winding drum during the welding process is controlled in a very small range, and the welding stability is significantly improved.

[0019] 2.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] See also Figures 1-8 As shown in , this embodiment provides a welding device with a roll loading and unloading clamping limit structure, including a mounting table 1, the upper end surface of the mounting table 1 has both left and right edges protruding upward, and the protruding structure is symmetrical front and back, as shown in FIG. Figure 2 As shown, an adjusting motor 101 is fixedly mounted on the outer surface of the protruding structure at the rear end on the left side, and a rotating shaft 102 is rotatably mounted on the inner sides of the two protruding structures at the front and rear ends. The rear end of the rotating shaft 102 on the left side is fixedly connected to the output shaft of the adjusting motor 101, and a conveyor belt 103 is rotatably mounted on the circumferential surface of the rotating shaft 102. Figure 2 shown.

[0025] Therefore, during use, the operation of the adjusting motor 101 will drive the rotating shaft 102 on the left to rotate, and the rotation of the rotating shaft 102 on the left will drive the conveyor belt 103 to move, and the movement of the conveyor belt 103 will drive the rotating shaft 102 on the right to rotate, thereby achieving the purpose of conveying the reel 5 that needs to be welded, improving the degree of automation of the device, and the surface of the conveyor belt 103 is provided with anti-slip grooves, which increases the friction between the conveyor belt 103 and the reel 5, preventing the reel 5 from sliding during the conveying process.

[0026] It should be noted that, during the operation of the conveyor belt 103 , since the reel 5 needs to be transported over a long distance, the length of the conveyor belt 103 needs to be set according to the actual situation on site.

[0027] Then, frames 2 are fixedly installed on the front and rear edges of the upper end face of the mounting platform 1, and limit rods 201 are fixedly installed on the left and right edges of the inner sides of the front and rear frames 2. The structure of the limit rod 201 is an I-shaped structure. Then, slide rods 202 are slidably installed on the outer sides of the left and right limit rods 201. The outer sides of both ends of the slide rods 202 are provided with matching sliding grooves 203. Therefore, when sliding with the limit rods 201, as shown in FIG. Figure 5 shown.

[0028] Furthermore, a telescopic cylinder 204 is fixedly mounted on the upper end surface of the mounting platform 1 and on the inner side surface of the frame 2, a U-shaped seat 205 is fixedly mounted on the telescopic rod of the telescopic cylinder 204 and the inner upper end surface of the frame 2, and a gear 207 is rotatably mounted on the inner side of the U-shaped seat 205, and a first motor 206 is fixedly mounted on the outer side surface of the lower end U-shaped seat 205, and the output shaft of the first motor 206 is fixedly connected to the adjacent gear 207, as shown in FIG. Figure 5 shown.

[0029] Then, a chain 208 is fixedly installed at the middle position of the upper end surface of the slide bar 202. The chain 208 passes through the U-shaped seat 205 and engages with the gear 207, and is then fixedly installed on the inner upper end surface of the frame 2.

[0030] Therefore, during use, when the reel 5 needs to be placed on the mounting platform 1 and is fitted with the subsequent main limit plate 301 and the auxiliary limit plate 303, the telescopic rod of the telescopic cylinder 204 is controlled to perform telescopic movement, so that the U-shaped seat 205 at the upper end drives the gear 207 to move up and down, thereby causing the chain 208 to move up and down. At this time, since the chain 208 is fixedly connected to the slide bar 202, the slide bar 202 will move up and down along the limit rod 201, thereby achieving the loading and unloading position restriction of the reel 5. At the same time, by starting the first motor 206, the output shaft of the first motor 206 drives the adjacent gear 207 to rotate. Since the gear 207 is engaged with the chain 208, the chain 208 drives the slide bar 202 to move up and down, thereby achieving fine adjustment of the position of the reel 5, so that the reel 5 can be accurately placed at the specified position, which is convenient for subsequent welding operations.

[0031] When the first motor 206 is used, the smooth operation of the chain 208 can be ensured, and the offset of the position of the reel 5 due to the shaking or jamming of the chain 208 can be avoided. In addition, the precise control of the first motor 206 enables each movement of the chain 208 to reach the predetermined position, thereby realizing fine-tuning of the position of the reel 5. This fine-tuning mechanism greatly improves the accuracy and efficiency of the welding operation, reduces the tediousness of manual adjustment, and also reduces the error during the operation. Therefore, the welding device, through clever design, not only realizes the loading and unloading positioning limit of the reel 5, but also ensures that the reel 5 can be accurately placed in the specified position through the precise control of the motor, which provides great convenience for subsequent welding operations.

[0032] Then, an adjusting cylinder 3 is fixedly installed in the middle of the slide rod 202, and a main limit plate 301 is fixedly installed on the telescopic rod of the adjusting cylinder 3. The outer sides of the upper and lower ends of the main limit plate 301 are fixedly installed with a forward and reverse motor 302, and the output shaft of the forward and reverse motor 302 is fixedly installed with a secondary limit plate 303. Figure 7 shown.

[0033] Secondly, grooves 304 are provided on the inner side surfaces of the main limiting plate 301 and the auxiliary limiting plate 303, and round rods 305 are rotatably installed at both ends of the main limiting plate 301 and the auxiliary limiting plate 303, and the round rods 305 pass through the grooves 304. Then, a limiting chain 306 is rotatably installed inside the grooves 304 and on the circumferential surface of the round rods 305, as shown in FIG. Figure 7 shown.

[0034] Therefore, during use, when it is necessary to limit the position of reels 5 of different sizes, the adjusting cylinder 3 can be started to make the telescopic rod drive the main limit plate 301 to move, and then adjust the distance between the main limit plate 301 and the auxiliary limit plate 303 to adapt to reels 5 of different sizes.

[0035] At the same time, the start of the forward and reverse motor 302 can drive the secondary limit plate 303 to rotate, so that the angle between the secondary limit plate 303 and the main limit plate 301 can be adjusted, further increasing the flexibility of the positioning limit.

[0036] The grooves 304 opened on the inner side surfaces of the main limiting plate 301 and the auxiliary limiting plate 303, as well as the round rod 305 and the limiting chain 306 rotatably installed inside the groove 304, together constitute a stable limiting structure. When the reel 5 is placed between the main limiting plate 301 and the auxiliary limiting plate 303, the limiting chain 306 will fit tightly on the surface of the reel 5, preventing the reel 5 from shaking or shifting during the loading and unloading process, thereby ensuring that the reel 5 can be stably positioned and limited.

[0037] Therefore, through this ingenious design, the welding device not only achieves precise positioning restriction of the reel 5, but also greatly improves the efficiency and stability of loading and unloading, providing a strong guarantee for subsequent welding operations.

[0038] Finally, a connecting plate 4 is fixedly installed between the inner upper ends of the front and rear frames 2, a second motor 401 is fixedly installed at the center of one end of the connecting plate 4, and a limiting groove 402 is provided on the lower end surface, and the output shaft of the second motor 401 extends to the inside of the limiting groove 402, and a reciprocating screw 410 is fixedly installed on the output shaft, as shown in FIG. Figure 8 shown.

[0039] Secondly, a slider 403 is threadedly installed on the circumferential surface of the reciprocating screw 410, and the upper end of the slider 403 is slidably installed in the interior of the limiting groove 402. The first connecting rod 404 is rotatably installed at the edge positions on both sides of the lower end of the slider 403, and a double-headed groove rod 405 is rotatably installed on the end of the first connecting rod 404 away from the slider 403. A third motor 406 is fixedly installed on the outer center of one of the double-headed groove rods 405, and the output shaft of the third motor 406 extends to the inner side of the double-headed groove rod 405, and a screw 407 is fixedly installed on the output shaft. The screw 407 and the other double-headed groove rod 405 are in a threaded rotation connection state, as shown in FIG. Figure 8 shown.

[0040] A second connecting rod 408 is rotatably mounted on the outer side of the lower end of the double-ended groove rod 405, and a welding gun 409 is rotatably mounted on one end of the second connecting rod 408 away from the double-ended groove rod 405. Figure 8 shown.

[0041] Therefore, during use, by starting the second motor 401, the reciprocating screw 410 can be driven to rotate, and since the slider 403 is threadedly mounted on the circumferential surface of the reciprocating screw 410, and the upper end of the slider 403 is slidably mounted inside the limiting groove 402, during the rotation of the reciprocating screw 410, the slider 403 can be driven to slide back and forth along the inside of the limiting groove 402, and during the sliding process of the slider 403, the double-headed groove rod 405 can be driven to move back and forth left and right through the first connecting rod 404. At this time, the third motor is started again. 406, can drive the screw 407 to rotate, and since the outer center of one of the double-headed grooved rods 405 is fixedly installed with a third motor 406, and the screw 407 and the other double-headed grooved rod 405 are in a threaded rotation connection state, therefore, during the rotation of the screw 407, it can drive the other double-headed grooved rod 405 to move back and forth left and right. When the two double-headed grooved rods 405 are close to each other, it can rotate the angle of the first connecting rod 404 and the second connecting rod 408, thereby allowing the welding gun 409 to approach or move away from the position where the reel 5 needs to be welded.
