Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically relating to a feeding mechanism for a welding robot. Background Technology

[0002] A welding robot is an industrial robot that performs welding. Welding robots typically have a mechanical structure similar to a human arm, which can move up and down, left and right, and forward and backward like a human arm. It can also rotate around different axes, which allows the robot to flexibly reach different welding positions.

[0003] Chinese Patent Publication No. CN221849109U discloses a translational welding robot, including a welding table. A moving component is mounted on one side of the welding table, an electric telescopic rod is connected to one end of the moving component, a rotating component is connected to the output end of the electric telescopic rod, an angle component is mounted on the lower part of the rotating component, a welding torch is connected to one side of the angle component, and a fume extraction component is connected to another side of the angle component. The fume extraction component includes a suction ring and a suction fan. The suction ring is connected to one side of the angle component, and dustproof holes are evenly spaced on one side of the suction ring, communicating with the inner cavity of the suction ring. A horn cover is fixedly connected to one side of the suction ring, and the welding torch is located in the middle of the suction ring and the horn cover. This utility model achieves welding of electrical cabinets through the cooperation of the moving component, electric telescopic rod, rotating component, angle component, welding torch, and fume extraction component, and purifies the fumes generated during welding.

[0004] While existing welding robots can purify the fumes generated during the welding process, the placement of the items to be welded and the removal of the welded items before and after welding are still manually operated. This not only greatly reduces the welding efficiency of the welding robot, but also cannot guarantee that the placement of the items to be welded is completely consistent each time, thus affecting the welding effect. Utility Model Content

[0005] The purpose of this invention is to provide a feeding mechanism for a welding robot to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a welding robot, comprising a placement platform, a welding robot fixedly connected to the top of the placement platform, a rotating disk rotatably connected to the outer side of the welding robot on the top of the placement platform, an intermittent feeding structure installed on the side of the rotating disk and the top of the placement platform, the intermittent feeding structure comprising a feeding groove arranged in a ring array on the outer surface of the rotating disk and an auxiliary block arranged in a ring array fixedly connected to the inner surface of the rotating disk, an adaptation groove being provided on the inner surface of the auxiliary block, a transmission disk rotatably connected to the top of the rotating disk, a limiting shaft fixedly connected to the top of the transmission disk, an arc-shaped groove being provided on the top of the limiting shaft, and a lever fixedly connected to the top of the transmission disk.

[0007] In a preferred embodiment, the lever is located outside the limiting shaft, the limiting shaft of the adapter groove is adapted to it, and a rotary motor is fixedly connected to the bottom of the placement platform. The transmission end of the rotary motor passes through the bottom of the placement platform and is fixedly connected to the bottom of the rotating disk.

[0008] In a preferred embodiment, an auxiliary groove is provided on the inner wall of the side surface of the feeding trough, and a clamping structure is installed inside the auxiliary groove. The clamping structure includes a limiting slide groove provided on the inner wall of the side surface of the auxiliary groove, and a support plate is installed inside the auxiliary groove. A limiting slider is fixedly connected to the side surface of the support plate.

[0009] In a preferred embodiment, the limiting slider is adapted to the limiting groove, and a helical spring is fixedly connected to the side surface of the support plate, with the end of the helical spring away from the support plate being fixedly connected to the inner wall of the auxiliary groove.

[0010] In a preferred embodiment, the inner wall of the material discharge trough is provided with a telescopic groove, and a push rod is slidably connected inside the telescopic groove. A push block is fixedly connected to the end of the push rod away from the telescopic groove, and the shape of the push block is adapted to the telescopic groove.

[0011] In a preferred embodiment, the top of the placement platform is provided with a positioning groove, and the interior of the positioning groove is connected to rotating balls in a circular array. The bottom of the rotating disk is fixedly connected with a positioning ring, and the bottom of the positioning ring is provided with a limit groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This invention involves placing two items to be welded inside the material feeding trough. A rotary motor is then started, causing a rotating disk at its transmission end to rotate. During this rotation, the disk drives a paddle block and a limiting shaft to rotate synchronously. The paddle block, in turn, moves an auxiliary block through an adapter groove. This auxiliary block, through its arc-shaped groove, rotates and moves. When the transmission disk completes one rotation, the adapter groove of the next auxiliary block covers the outside of the limiting shaft. This process continues until the rotation of the transmission disk drives the paddle block to move again, resulting in intermittent rotation. This achieves a uniform replacement of the material feeding trough below the welding robot, facilitating subsequent welding of items in each trough by the welding robot. This effectively improves the accuracy of item placement and the welding quality.

[0014] In this invention, when two items to be welded are placed in the auxiliary groove, the thickness of the items themselves will exert pressure on the support plate, causing the helical spring to contract. During the contraction process, the helical spring will use its elasticity to drive the support plate to support the items, thereby playing a role in fixing them. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figure 1-5 This utility model provides a feeding mechanism for a welding robot, including a placement platform 1. A welding robot 2 is fixedly connected to the top of the placement platform 1. A rotating disk 3 is rotatably connected to the outer side of the welding robot 2 on the top of the placement platform 1. An intermittent feeding structure is installed on the side of the rotating disk 3 and the top of the placement platform 1. The intermittent feeding structure includes a feeding groove 31 arranged in a ring array on the outer surface of the rotating disk 3 and an auxiliary block 32 arranged in a ring array fixedly connected to the inner surface of the rotating disk 3. An adaptation groove 33 is provided on the inner surface of the auxiliary block 32. A transmission disk 34 is rotatably connected to the top of the rotating disk 3. A limiting shaft 35 is fixedly connected to the top of the transmission disk 34. An arc-shaped groove 36 is provided on the top of the limiting shaft 35. A toggle block 37 is fixedly connected to the top of the transmission disk 34.

[0024] First, place the two items to be welded inside the material feeding trough 31. Then, start the rotary motor 4 to drive the rotary disk 3 at its transmission end to rotate. During the rotation of the rotary disk 3, the toggle block 37 and the limiting shaft 35 will rotate synchronously. During the rotation, the toggle block 37 will move the auxiliary block 32 through the adapter groove 33. The auxiliary block 32 will rotate and move through the arc groove 36. When the transmission disk 34 completes one rotation, the adapter groove 33 of the next auxiliary block 32 will cover the outside of the limiting shaft 35 until the rotation of the transmission disk 34 drives the toggle block 37 to move again, which plays a role in intermittent rotation. This achieves the effect of uniformly changing the material feeding trough 31 below the welding robot 2, which makes it easier for the welding robot 2 to weld the items in each trough. This effectively improves the accuracy of the item placement and the welding quality.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, the lever 37 is located outside the limiting shaft 35, and the limiting shaft 35 of the adapter groove 33 is adapted to it. The bottom of the placement platform 1 is fixedly connected to the rotary motor 4, and the transmission end of the rotary motor 4 passes through the bottom of the placement platform 1 and is fixedly connected to the bottom of the rotating disk 3.

[0026] The output of the rotary motor 4 drives the rotary disk 3 to rotate.

[0027] Specifically, such as Figure 5As shown, an auxiliary groove 5 is provided on the inner wall of the side surface of the feeding groove 31. A clamping structure is installed inside the auxiliary groove 5. The clamping structure includes a limiting slide groove 51 provided on the inner wall of the side surface of the auxiliary groove 5. A support plate 52 is installed inside the auxiliary groove 5. A limiting slider 53 is fixedly connected to the side surface of the support plate 52.

[0028] The limiting slider 53 is adapted to the limiting groove 51. A helical spring 54 is fixedly connected to the side surface of the support plate 52. The end of the helical spring 54 away from the support plate 52 is fixedly connected to the inner wall of the auxiliary groove 5.

[0029] When two items to be welded are placed in the auxiliary slot 5, the thickness of the items themselves will exert pressure on the support plate 52, causing the coil spring 54 to contract. During the contraction process, the coil spring 54 will use its elasticity to drive the support plate 52 to support the items, thereby playing a fixing role.

[0030] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, the inner wall of the material feeding trough 31 is provided with a telescopic groove 6, and a push rod 7 is slidably connected inside the telescopic groove 6. A push block 8 is fixedly connected to the end of the push rod 7 away from the telescopic groove 6, and the shape of the push block 8 is adapted to the telescopic groove 6.

[0031] After the welding robot 2 welds the items inside the material trough 31 together, it can push the push block 8 by pushing the push rod 7 to move the items, thereby emptying the material trough 31 and making it convenient for the staff to put items in again.

[0032] Specifically, such as Figure 2 and Figure 4 As shown, a positioning groove 9 is provided on the top of the placement platform 1. Rotating balls 10 are rotatably connected in a ring array inside the positioning groove 9. A positioning ring 11 is fixedly connected to the bottom of the rotating disk 3. A limit groove 12 is provided at the bottom of the positioning ring 11.

[0033] The rotating ball bearing 10 can reduce the friction between the positioning groove 9 and the positioning ring 11 and improve the lubrication.

[0034] The working principle and usage process of this utility model are as follows: During use, two items to be welded are first placed inside the feeding trough 31. Then, the rotary motor 4 is started, which drives the rotary disk 3 at its transmission end to rotate. During the rotation of the rotary disk 3, the push block 37 and the limiting shaft 35 rotate synchronously. During the rotation, the push block 37 pushes the auxiliary block 32 through the matching groove 33. The auxiliary block 32 rotates and moves through the arc groove 36. When the transmission disk 34 completes one rotation, the matching groove 33 of the next auxiliary block 32 will cover the outside of the limiting shaft 35 until the rotation of the transmission disk 34 drives the push block 37 to push again, which plays the role of intermittent rotation. This achieves the effect of uniform replacement of the feeding trough 31 below the welding robot 2, which makes it convenient for the welding robot 2 to weld the items in each trough. This effectively improves the accuracy of the item placement and the welding quality.

[0035] Then, when the rotating disk 3 rotates to a certain angle, the welding robot 2 will weld the items inside the material trough 31. The rotating disk 3 will automatically take away the welded items, and the unwelded items will automatically move to the bottom of the welding robot 2 for welding. Finally, the push rod 7 pushes the push block 8 to move the items, thereby freeing up the material trough 31 for the staff to place items again.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
