Description

Technical Field

[0001] This utility model relates to the field of lap welding equipment, specifically a welding rod folding device used in a lap welding machine. Background Technology

[0002] With the continuous growth of energy demand and the increasing prominence of environmental issues, solar power generation, as a clean and renewable energy form, has received widespread attention. Photovoltaic modules, as the core component of solar power generation systems, play an important role in converting solar energy into electrical energy.

[0003] Stacking welding machines connect solar cells in series using welding rods and busbars. In some special processes, welding rods are intermittently welded onto the solar cells, with the welding rods exposed at both ends of the cells. Busbars are then used to weld the exposed ends of the welding rods together. At this point, workers need to fold the welding rods at both ends of the solar cells at a specified angle. However, manual folding is inefficient and not conducive to automated deployment; therefore, a device for this folding operation needs to be designed. Utility Model Content

[0004] To address the problems in the prior art, this application provides a welding electrode folding device for use in a lap welding machine, which enables automated folding of welding electrodes and improves production efficiency.

[0005] The technical solution is as follows:

[0006] A welding rod folding device for use in a lap welding machine includes a mounting frame with connecting mechanisms at both ends and a folding mechanism on the side of the mounting frame. The folding mechanism includes a bracket with a rotatable shaft and a connecting rod on one side of the bracket. The shaft and the connecting rod are connected and driven by a transmission component. A motor A for driving the shaft to rotate is mounted on the bracket, and paddles are spaced apart on the connecting rod.

[0007] Preferably, a vertical rail is provided on the other side of the bracket, and a slider is provided on the mounting frame. The mounting frame and the bracket are connected by the cooperation of the vertical rail and the slider. A rack is provided on the other side of the bracket, and a motor B is provided on the mounting frame. A gear that meshes with the rack is provided at the output end of the motor B.

[0008] Specifically, the transmission component includes a driving wheel and a driven wheel mounted on the bracket. The driving wheel and the driven wheel are respectively connected to the end of the rotating shaft and the end of the connecting rod, and the driving wheel and the driven wheel are connected by a transmission belt.

[0009] Specifically, the transmission component also includes a tensioning wheel, which is mounted on the bracket and is used to adjust the tension of the transmission belt.

[0010] Specifically, the connecting mechanism includes a horizontal rail mounted on the mounting frame, a slider mounted on the horizontal rail, a sliding plate mounted on the top surface of the slider, a bearing seat mounted above the sliding plate, a bearing seat containing a bearing, the sliding plate and the bearing seat being connected by a coupling, the top of the bearing being connected to the bearing, and its bottom being connected to the sliding plate; a connecting member is mounted on the side of the bearing seat, and the connecting member is connected to an external driving component.

[0011] Preferably, the bracket is provided with an extension plate.

[0012] Preferably, symmetrical stops are provided on the other side of the bracket.

[0013] Preferably, the rotating shaft and the motor A are driven by gear meshing; or, the rotating shaft and the motor A are driven by a belt.

[0014] In summary, by placing the battery end and a portion of the welding rod on the extension plate, and the busbar and a portion of the welding rod on the lever, motor A operates, controlling the lever to flip, thereby bending the welding rod to a specified angle without manual bending. This significantly improves production efficiency and increases the overall automation rate of the equipment. Simultaneously, motor B controls the lifting and lowering of the folding mechanism, driving the entire welding rod folding device horizontally. Through the coordinated movement of these two mechanisms, the lever can be moved to the designated position, ensuring that the busbar and a portion of the welding rod are accurately placed on the lever, improving folding accuracy.

[0023] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0024] like Figure 1 and Figure 2 As shown, the connecting mechanism 3 is installed at both ends of the mounting bracket 1, and the folding mechanism 2 is installed on the side of the mounting bracket 1. Figure 4 As shown, the folding mechanism 2 includes a bracket 201. A rotating shaft 202 and a connecting rod 203 are respectively provided on the upper and lower sides of one side of the bracket 201. Both the rotating shaft 202 and the connecting rod 203 can rotate. The rotating shaft 202 and the connecting rod 203 are connected by a transmission component. The transmission component is installed on the outer side of the bracket 201. At the same time, a motor A206 that drives the rotating shaft 202 to rotate is installed on the bracket 201. The paddles 204 are installed on the connecting rod 203 at intervals.

[0025] Motor A206 drives shaft 202 to rotate, which, through the connection of transmission components, drives connecting rod 203 to rotate, ultimately driving lever 204 to rotate. Connecting mechanism 3 connects to an external mobile device, which can be a belt-driven or cylinder-driven device capable of linear movement. The mobile device moves mounting bracket 1, causing lever 204 to move below the welding rods at both ends of the battery cell, placing the busbars and welding rods on lever 204. It should be noted that the number of levers 204 is determined by the number of busbars; when welding three busbars, three levers 204 are required. Motor A206 operates, driving lever 204 to rotate, which in turn causes the busbars and welding rods to flip, folding the welding rods.

[0026] like Figure 4 and Figure 5 As shown, the transmission components include a driving wheel 207 and a driven wheel 209. The driving wheel 207 is mounted on both ends of the bracket 201 and connected to both ends of the rotating shaft 202. Similarly, the driven wheel 209 is mounted on both ends of the bracket 201 and connected to both ends of the connecting rod 203. The driving wheel 207 and the driven wheel 209 are connected by a transmission belt 210, with both ends of the transmission belt 210 wrapped around the driving wheel 207 and the driven wheel 209, respectively. A tensioning wheel 208 is also mounted on the bracket 201. The tensioning wheel 208 contacts the transmission belt 210 and adjusts its tension. To facilitate the adjustment of the tensioning wheel 208, a slot is provided in the bracket 201. The tensioning wheel 208 moves within the slot to adjust the tension of the transmission belt 210. After adjustment, it is locked and fixed. The motor A206 drives the rotating shaft 202 to rotate, which in turn drives the driven wheel 209 to rotate via the transmission belt 210, ultimately causing the connecting rod 203 to rotate.

[0027] like Figure 2 and Figure 5 As shown, since the heights of the welding rod and the lever 204 are inconsistent, a vertical rail 211 is installed on the other side of the bracket 201, and a matching slider is installed on the mounting frame 1. The slider is installed on the vertical rail 211 to connect the bracket 201 and the mounting frame 1, allowing the bracket 201 to move up and down along the vertical rail 211 on the mounting frame 1. Simultaneously, a rack 213 is vertically installed on the same side of the bracket 201 as the vertical rail 211, and a motor B4 is installed on the mounting frame 1. A gear that meshes with the rack 213 is installed on the shaft of the motor B4. When the motor B4 operates, the meshing of the gear and rack 213 drives the rack 213 to move vertically, thereby moving the bracket 201 along the vertical rail 211 and moving the lever 204 to the specified height, allowing the busbar and welding rod to fall onto the lever 204.

[0028] To prevent the mounting bracket 1 from tilting during movement, drive devices are connected to both ends of the mounting bracket 1. However, the speeds of the drive devices at both ends must be consistent. If they are inconsistent, it will cause the speeds at both ends of the mounting bracket 1 to be different, which could lead to belt strain or even breakage. Therefore, connecting mechanisms 3 are required at both ends of the mounting bracket 1.

[0029] like Figure 3As shown, the connecting mechanism 3 includes a horizontal rail 301, which is mounted on the mounting frame 1. A slider 302 is mounted on the horizontal rail 301, and a sliding plate 306 is mounted on the top surface of the slider 302. The bottom of the connecting shaft 303 is mounted on the sliding plate 306. A bearing seat 304 is provided on the top of the connecting shaft 303, and a bearing is installed inside the bearing seat 304, connecting the bearing to the top of the connecting shaft 303. A connecting piece 305 is provided on the side of the bearing seat 304. An external drive device is provided, which adopts a structure where a motor drives a belt to rotate. The connecting piece 305 shown in the figure is a structure for connecting to the belt. Specifically, a clamp is used to fix the belt in place. The drive device drives the belt to rotate, thereby driving the mounting frame 1 to move toward or away from the battery cells. When the speeds of the drive devices at both ends of the mounting bracket 1 are inconsistent, the bearing seat 304 rotates around the connecting shaft 303 through the action of the bearing, while the slider 302 moves along the horizontal track 301. The speed is compensated by rotation and movement, thereby ensuring that the speeds on both sides are consistent and avoiding accidents.

[0030] like Figure 4 As shown, an extension plate 205 is provided on the side of the bracket 201 facing the battery cell. The end of the battery cell and part of the welding rod can be placed on the extension plate 205 and supported by the extension plate 205.

[0031] like Figure 5 As shown, a stop block 212 is provided on one side of the bracket 201 located on the vertical track 211. The stop block 212 is symmetrically arranged at the upper and lower ends of the side of the bracket 201. At the same time, a blocking component is also provided on the mounting bracket 1 corresponding to the stop block 212. Through the cooperation of the stop block 212 and the blocking component, the bracket 201 can be prevented from sliding out of the vertical track 211.

[0032] It should be noted that there are two transmission methods between the rotating shaft 202 and the motor A206. One method involves gears being installed on both the rotating shaft 202 and the drive shaft of the motor A206, with the gears meshing together. When the motor A206 operates, the rotation of the rotating shaft 202 is achieved through the meshing of the gears. The other method involves wrapping the two ends of a belt around the drive shaft of the motor A206 and the rotating shaft 202, respectively. When the motor A206 operates, the rotation of the rotating shaft 202 is achieved through the connection of the belt. This embodiment uses the first transmission method.

[0033] In practical operation, this welding rod folding device is installed on the stacking welding machine at both ends of the battery cell, and the connecting piece 305 is connected to the belt of the drive equipment. The drive equipment drives the mounting bracket 1 to move towards the battery cell, while the motor B4 operates, and the drive bracket 201 moves downward along the vertical track 211. Through horizontal and vertical movement, the lever 204 moves to below the welding rod and busbar. Then, the motor B4 drives the bracket 201 to rise a short distance, so that the end of the battery cell and part of the welding rod are placed on the extension plate 205. At this time, the motor A206 drives the rotating shaft 202 to rotate, which drives the driven wheel 209 to rotate, realizing the rotation of the connecting rod 203, and finally driving the lever 204 to rotate. This, in turn, causes the busbar and welding rod to flip, so that the welding rod is folded to the specified angle.

This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not described herein.
