DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0030] Example: See Figure 1 - Figure 5 In this embodiment, a welding device 1 for conveyor chain production is involved, which is specifically used for automatically welding the angle code of the conveyor chain to improve production efficiency and welding quality and reduce manual labor intensity. The device is particularly suitable for large-scale industrial production lines, in which the conveyor chain needs to quickly and frequently connect the angle code with the chain. Specifically, it includes: an angle code conveying unit 11, a chain conveying unit 12 and a welding unit 13; the angle code conveying unit 11 adopts intermittent transmission by a synchronous belt transmission mechanism 4, and a pusher component 3 is arranged on one side, and the pusher component 3 pushes the angle code from the synchronous belt transmission mechanism 4 to the welding station; the chain conveying unit 12 adopts a sprocket and chain meshing mode to convey, and conveys the chain to be welded from the chain input end 14 to the welding station, and conveys the chain after welding to the chain output end 15; the welding unit 13 is located above the welding station, and includes a three-axis moving component 5, and the three-axis moving component 5 is connected and fixed with a welding gun 131, and the three-axis moving component 5 drives the welding gun 131 to move to the welding station.

[0031] Specifically, in this embodiment, the angle code conveying unit 11 intermittently transmits the angle code to the welding station through the synchronous belt transmission mechanism 4 to ensure the continuous supply of the angle code. The pushing component 3 is on one side of the synchronous belt transmission mechanism 4. When the angle code reaches the predetermined position (aligned with the active end of the pushing component 3), the pushing component 3 of the utility model adopts an electric push rod 31, and the electric push rod 31 pushes the angle code to the welding station (the upper surface of the chain to be welded). The chain conveying unit 12 uses the meshing mode of the sprocket and the chain to smoothly convey the chain to be welded from the chain input end 14 to the welding station (below the angle code). After welding is completed, the chain is conveyed to the chain output end 15 for subsequent processing or inspection to ensure the stability and continuity of the chain during the welding process. During the welding process of the welding unit 13, the three-axis moving component 5 drives the welding gun 131 to move accurately in the three spatial dimensions of the X, Y, and Z axes to achieve welding of the angle code and the chain. The welding device 1 of this embodiment not only reduces the intensity of manual labor through automated conveying and welding processes, but also improves production efficiency. Compared with manual operations with human errors, the angle codes welded by the welding device 1 have better consistency: the angle codes are provided with connecting holes for installing chain plates, and the connecting holes on each chain link have the same relative position, so that when the chain plates are installed later, the holes at both ends of the chain plates can be aligned with the connecting holes on the angle codes, which facilitates the installation of the chain plates.

[0032] The chain conveying unit 12 comprises an input sprocket 21 at the chain input end 14, a positioning sprocket 22 at the welding station and an output sprocket 23 at the chain output end 15, and the input sprocket 21, the positioning sprocket 22 and the output sprocket 23 are all connected to a sprocket motor 24 adapted to drive the rotation thereof. The input sprocket 21 and the output sprocket 23 in the present embodiment are respectively fixed to the left and right sides inside the device body through a bearing seat, and the sprocket motor 24 driving the two sprockets (input sprocket 21 and output sprocket 23) to rotate is located above the bearing seat. The positioning sprocket 22 is located between the input sprocket 21 and the output sprocket 23, and the sprocket motor 24 connected to the lower end of the positioning sprocket 22 drives it to rotate. The input sprocket 21, the positioning sprocket 22 and the output sprocket 23 are arranged in a staggered manner, wherein the input sprocket 21 and the output sprocket 23 are located on the same side. The sprocket motor 24 can be driven individually or synchronously, so that the chain can be transported stably. In particular, the input sprocket 21 and the output sprocket 23 are rotated in opposite directions so that the chain is tightened before welding, ensuring that the chain position is fixed during welding.

[0033] See also Figure 3The angle code conveying unit 11 is slidably connected to a limiting component 32 at one side of the welding station. The limiting component 32 is provided with a reset spring 33. The reset spring 33 drives the limiting component 32 to pull toward the side of the pushing component 3. The pushing component 3 pushes the angle code to move toward the welding station. The folded edge 34 of the angle code is clamped between the movable end of the pushing component 3 and the limiting component 32. In this embodiment, the angle code conveying unit 11 is provided with a conveying channel 35 for passing the angle code along the direction of the synchronous belt transmission mechanism 4, so that the position of the angle code is always consistent during the conveying process. The angle code conveying unit 11 is provided with a conveying groove 36 at one side of the pushing component 3. The width of the conveying groove 36 gradually decreases from the pushing component 3 to the welding station side until it is the same as the width of the angle code, so that the angle code can be automatically positioned on the left and right sides when it is pushed to the welding station. The limiting component 32 starts to contact the folded edge 34 of the angle code only when the pushing component 3 pushes the angle code out of the synchronous belt transmission mechanism 4, and then the pushing component 3 starts to push the limiting component 32. At this time, the reset spring 33 is stretched until the angle code is pushed to the welding station (the upper surface of the chain to be welded). In this embodiment, the limiting component 32 limits the angle code by contacting the folded edge 34 of the angle code through its side protrusion 321, so as to prevent the angle code from tipping over when being pushed out by the pushing component 3. After welding is completed, the positioning sprocket 22 drives the welded chain link to rotate, so that the angle code is peeled off from one side of the protrusion 321 of the limiting component 32, and then the pushing component 3 is retracted. The limiting component 32 returns to the initial state again under the action of the reset spring 33, and a working cycle is realized.

[0034] See also Figure 4 The synchronous belt transmission mechanism 4 includes a transmission belt 41, and the two ends of the transmission belt 41 are respectively sleeved on two pulleys 42, and the shaft of any pulley 42 is connected to a synchronous belt motor 43 adapted to drive the rotation thereof. In this embodiment, the angle code is placed on one side of the synchronous belt transmission mechanism 4, and the transmission belt 41 is driven by the synchronous belt motor 43, so that the angle code moves toward the pushing component 3 in sequence. In addition, a tensioning wheel 44 is also provided between the two ends of the transmission belt 41, and the outer side of the tensioning wheel 44 is in contact with the transmission belt 41, which helps to reduce the slippage of the transmission belt 41, thereby maintaining the stability of the synchronous belt transmission mechanism 4 when conveying the angle code.

[0035] See also Figure 5The three-axis moving component 5 includes a first linear module 51, which is fixed to the top of the inner side of the device body and drives the welding gun 131 to move left and right; a second linear module 52, which is connected and fixed to the movable end of the first linear module 51 and drives the welding gun 131 to move forward and backward; a third linear module 53, which is connected and fixed to the movable end of the second linear module 52 and drives the welding gun 131 to move up and down. The movable end of the third linear module 53 is connected and fixed to the welding gun 131 through a servo gear 54, allowing the welding gun 131 to be adjusted at a finer angle. The first linear module 51 and the second linear module 52 both use ball screws. The third linear module 53 uses a servo electric cylinder, which has precise position control and rapid response capabilities. Through the coordinated work of the above components, the welding gun 131 can be flexibly moved in three-dimensional space to meet the precise positioning requirements of the welding gun 131.

[0036] See also Figure 6 The side of the device body is provided with a transparent window 16 for sliding, allowing the operator to observe the welding process in real time and check whether there are defects in the welding joint, such as pores, lack of fusion, and lack of penetration, through the transparent window 16, so as to ensure visual monitoring of the welding process, and help to find problems early and take corrective measures. The transparent window 16 is made of low-emissivity glass (Low-E glass) and has an ultraviolet isolation film on its outer surface, which protects the operator from the influence of ultraviolet radiation.
