Description

Technical Field

[0001] This utility model belongs to the field of robot manufacturing technology, and specifically relates to a quick change mechanism for a wire feeding device. Background Technology

[0002] Intelligent robots are automated systems that integrate multiple advanced technologies such as artificial intelligence (AI), sensor technology, mechanical engineering, and control theory. They are capable of performing complex tasks and have the ability to perceive the environment, make decisions, act autonomously, and learn. In the production and research and development of intelligent robots, cable laying devices are used to lay cables inside mechanical equipment.

[0003] Existing wire feeding devices use a quick-change mechanism. The wire feeding roller to be installed is placed in a slot and then secured by a spring-loaded locking module, connecting it to a turntable for quick replacement. During wire feeding, a motor drives the connected turntable, which in turn rotates the fixed wire feeding roller, thus controlling its direction. However, due to the large amount of cable used in production, frequent disassembly and replacement of the wire feeding roller are necessary. The springs in the locking module, after prolonged use, are frequently compressed and restored, potentially reducing their resilience and affecting the securing effect on the wire feeding roller. This necessitates manual removal and replacement of the locking module, which is inconvenient. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a quick-change mechanism for a wire feeding device. This mechanism can quickly and securely clamp and fix the wire feeding roller when changing it, effectively ensuring the fixation effect of the wire feeding roller after long-term use and facilitating the quick replacement of the wire feeding roller.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a quick-change mechanism for a wire feeding device, including a base, a bracket provided on the upper surface of the base, a mounting box provided in the middle of the inner side of the bracket, a rotating cylinder rotatably mounted between the mounting box and the bracket, a mounting groove provided on the side of the rotating cylinder near the vertical center of the base, a fixing module for fixing the wire feeding roller provided on the rotating cylinder, and an electrical control module for driving the rotating cylinder to rotate between the bracket and the rotating cylinder; symmetrically distributed fixing plates are provided on the front and rear sides of the base, symmetrically distributed fixing holes are provided on the upper surface of the fixing plates, and a buffer pad is provided on the lower surface of the fixing plates.

[0006] As a further improvement of this utility model, the electrical control module includes a worm gear fixedly sleeved on the outer arc surface of the rotating cylinder. U-shaped seats are provided on the lower inner sides of both the left and right sides of the bracket. A worm is rotatably installed inside each U-shaped seat. The worm is meshed with the adjacent worm gear. An electrical control unit for driving the worm to rotate is also provided on the U-shaped seat. The electrical control unit includes a drive motor located on the rear side of the U-shaped seat. The output shaft of the drive motor is fixed to the adjacent worm through a coupling.

[0007] As a further improvement of this utility model, the fixing module includes guide grooves evenly opened on the side of the rotating cylinder near the vertical center of the base. Sliding columns are slidably arranged inside the guide grooves. Limiting clamps are provided on the side of the sliding columns near the vertical center of the base. The rotating cylinder is also provided with a driving unit for driving the limiting clamps to move. The driving unit includes guide rails evenly arranged inside the rotating cylinder. Sliding disks are symmetrically distributed between adjacent guide rails. Connecting rods are evenly distributed on the outer side of the sliding disks. Sliding rods are provided between the ends of two horizontally adjacent connecting rods away from the horizontal center of the rotating cylinder. The sliding rods are respectively connected and fixed to adjacent sliding columns. A bidirectional lead screw is rotatably arranged in the middle of the rotating cylinder. The sliding disks are threadedly connected to the bidirectional lead screw. A knob is provided at the end of the bidirectional lead screw away from the vertical center of the base.

[0008] As a further improvement of this utility model, a control box is provided on the front side of the bracket, and all drive motors are electrically connected to the control box.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, when it is necessary to replace the pay-off roller during use, slide the pay-off roller to be replaced between the two mounting slots, and then turn the knobs on the left and right sides to make the sliding column drive the limit clamp to move towards the side closer to the horizontal center of the rotating cylinder, so as to quickly and stably clamp and fix the pay-off roller.

[0011] Secondly, the knobs drive the bidirectional lead screws connected to them to rotate, which in turn causes the two sliding discs threaded to them to move in opposite directions between the guide rails. This causes the sliding discs to drive the sliding column to slide inside the guide groove through the connecting rod, which in turn causes the limit clamp to move stably.

[0012] Third, by controlling the operation of the drive motor, the worm gear drives the rotating drum to rotate, which in turn drives the feeding roller to rotate, thereby achieving the feeding of the wire.

[0013] Fourth, the buffer pad on the lower surface of the fixed plate can effectively prevent damage to the base caused by excessive tightening of bolts during installation. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 2 As shown, the system includes a base 101, a bracket 104 on the upper surface of the base 101, a mounting box 105 in the middle of the inner side of the bracket 104, a rotating cylinder 106 rotatably mounted between the mounting box 105 and the bracket 104, and a mounting groove 107 on the side of the rotating cylinder 106 near the vertical center of the base 101. A fixing module for fixing the wire feeding roller is also provided on the rotating cylinder 106. An electrical control module for driving the rotating cylinder 106 to rotate is also provided between the bracket 104 and the rotating cylinder 106.

[0022] like Figure 2 , 4As shown, the electrical control module includes a worm gear 210 fixedly sleeved on the outer arc surface of the rotating cylinder 106. U-shaped seats 211 are provided on the lower inner sides of both the left and right sides of the bracket 104. Worms 212 are rotatably installed inside each U-shaped seat 211. The worms 212 are respectively meshed with the adjacent worm gears 210. An electrical control unit for driving the worms 212 to rotate is also provided on the U-shaped seat 211. The electrical control unit includes a drive motor 213 located on the rear side of the U-shaped seat 211. The output shaft of the drive motor 213 is fixed to the adjacent worms 212 by couplings.

[0023] like Figure 2 , 3 As shown, the fixing module includes guide grooves 201 evenly spaced on one side of the rotating cylinder 106 near the vertical center of the base 101. Sliding columns 202 are slidably disposed inside each guide groove 201. Limiting clamps 203 are provided on the side of each sliding column 202 near the vertical center of the base 101. A driving unit for moving the limiting clamps 203 is also provided on the rotating cylinder 106. The driving unit includes guide rails 205 evenly spaced inside the rotating cylinder 106, with symmetrically distributed guide rails 205 slidably spaced between adjacent guide rails 205. The sliding disk 206 has evenly distributed connecting rods 207 rotatably arranged on its outer side. A sliding rod 204 is arranged between the ends of two horizontally adjacent connecting rods 207 away from the horizontal center of the rotating cylinder 106. The sliding rods 204 are respectively connected and fixed to the adjacent sliding columns 202. A bidirectional lead screw 208 is rotatably arranged in the middle of the interior of the rotating cylinder 106. The sliding disk 206 is threadedly connected to the bidirectional lead screw 208. A knob 209 is arranged at the end of the bidirectional lead screw 208 away from the vertical center of the base 101.

[0024] like Figure 1 As shown, a control box 301 is provided on the front side of the bracket 104, and the drive motors 213 are all electrically connected to the control box 301.

[0025] When replacing the pay-off roller during use, the operator slides the pay-off roller to be replaced between the two mounting slots 107, and then rotates the knobs 209 on both sides. This causes the knobs 209 to rotate the bidirectional lead screw 208 connected to them, which in turn causes the two threaded sliding discs 206 connected to them to move in opposite directions between the guide rails 205. During the movement of the sliding discs 206, the sliding discs 206 rotate with the connecting rod 207, and the connecting rod 207 rotates with the sliding rod 204. This causes the sliding discs 206 to drive the sliding column 204 via the connecting rod 207. 2. The sliding column 202 slides inside the guide groove 201, causing the limiting clamp 203 to move towards the side closer to the transverse center of the rotating drum 106, thereby quickly and stably clamping and fixing the wire feeding roller. The drive motor 213 is controlled to operate, so that the output shaft of the drive motor 213 drives the worm gear 212 connected to it to rotate. Then, through the meshing relationship between the worm gear 212 and the worm wheel 210, the worm wheel 210 is driven to rotate, which in turn drives the rotating drum 106 to rotate. The rotation of the rotating drums 106 on both sides drives the wire feeding roller to rotate, thereby realizing wire feeding.

[0026] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, symmetrically distributed fixing plates 102 are provided on both the front and rear sides of the base 101. The upper surface of each fixing plate 102 has symmetrically distributed fixing holes 103, and the lower surface of each fixing plate 102 has a buffer pad. When installing the base 101, personnel will pass the bolts through the fixing holes 103 and then use external tools to tighten the bolts to fix the base 101 to the ground. The buffer pads on the lower surface of the fixing plates 102 effectively prevent damage to the base 101 caused by excessive tightening of the bolts during installation.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
