Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for photovoltaic frame production, specifically to a welding device for photovoltaic frame production. Background Technology

[0002] Square photovoltaic frames are a type of photovoltaic frame that has good stability and symmetry. They can evenly distribute pressure, provide reliable support for solar modules, effectively resist external forces such as wind pressure and snow loads, and protect the internal cells from mechanical stress.

[0003] In existing technologies, the manufacturing of photovoltaic frames requires the sequential welding of the four edge strips (parts to be welded) that make up the photovoltaic frame. During the welding process, it is necessary to frequently clamp, release, turn, and re-clamp the semi-finished product (a component made of two or three edge strips) to adjust the position of the semi-finished product in order to weld all the joints of the edge strips. Alternatively, workers can hold a welding gun and constantly adjust their own position to weld the joints of the four edge strips. The entire manufacturing process is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide a welding device for photovoltaic frame production, in order to solve the technical problem that the manufacturing process of photovoltaic frames is complicated by the need to frequently adjust the position of semi-finished products or the workers themselves to weld the joints of the edge strips.

[0008] As a further technical solution of the above scheme, the upper surface of the base is provided with a circular mounting groove, and a vertical positioning shaft is provided at the center of the mounting groove; the rotating assembly includes a drive motor, a driving gear, and a driven gear; the drive motor is located on the lower surface of the base, and the output shaft of the drive motor passes through the upper surface of the base and is connected to the driving gear; the driven gear is located at the lower part of the movable plate, and a bearing is embedded in the middle of the driven gear, and the rotation axis of the movable plate, the axis of the driven gear, and the axis of the bearing coincide; the movable plate is rotatably mounted on the positioning shaft through the bearing, and the driven gear meshes with the driving gear.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0018] like Figures 1-5 As shown, a welding device for photovoltaic frame production includes a base 1, a movable plate 2, a clamping assembly 3, a rotating assembly, and a welding assembly 5. Movable plate 2 is rotatably mounted on base 1; The clamping assembly 3 is disposed on the side of the movable plate 2 away from the base 1 and is used to clamp the parts to be welded. In this embodiment, the parts to be welded refer to the edge strips used to produce photovoltaic frames. The rotating component is mounted on the base 1, and the moving end of the rotating component is connected to the movable plate 2 for driving the movable plate 2 to rotate. The welding assembly 5 includes a robotic arm and a laser welding gun 54; the robotic arm is mounted on the base 1, and the laser welding gun 54 is mounted on the moving end of the robotic arm; the position of the laser welding gun 54 is adjusted by the robotic arm to weld the parts to be welded.

[0019] When using this device, the operator can place multiple edge strips of equal length on the movable plate 2 for splicing. In this embodiment, there are four edge strips. The ends of the four edge strips are connected in sequence to form a square frame structure. Then, the four edge strips are clamped and fixed by the clamping component so that the relative positions of the four edge strips are fixed. Then, the position of the laser welding gun 54 is adjusted by the robotic arm so that the welding end of the laser welding gun 54 corresponds to one of the welding positions of the four edge strips (the joint between two adjacent edge strips). At this time, the operator can start the laser welding gun 54 and use the laser welding gun 54 to weld at that position. After welding at this position is completed, the worker can adjust the position of the movable plate 2 by rotating the component, so that the movable plate 2 rotates 90° around its rotation axis. At this time, the welding end of the laser welding gun 54 corresponds to another position to be welded on the four edge strips. The above welding steps are repeated again. Then, the position of the movable plate 2 is adjusted by rotating the component again and the welding work continues until all four positions to be welded are completed, thus completing the production of the photovoltaic frame.

[0020] The device uses clamping assembly 3 to clamp and fix the frame structure composed of multiple edge strips onto movable plate 2, thus fixing the relative positions of the multiple edge strips. Then, the position of laser welding gun 54 is adjusted by a robotic arm so that the welding end of laser welding gun 54 corresponds to one of the joints of the multiple edge strips and performs welding operation. After the welding of this joint is completed, the position of multiple edge strips can be quickly adjusted by rotating assembly to make the other joint of multiple edge strips correspond to the welding end of laser welding gun 54, and the welding end of laser welding gun 54 welds at this position. This process is repeated until all joints of multiple edge strips are welded to complete the manufacturing of photovoltaic frame. The entire process does not require frequent clamping, releasing, turning and re-clamping of multiple edge strips, thus simplifying the manufacturing process of photovoltaic frame.

[0021] Preferably, the aforementioned robotic arm includes a hydraulic telescopic rod 51, an electric push rod 52, and a retaining ring 53; the hydraulic telescopic rod 51 is vertically mounted on the base 1, and the electric push rod 52 is mounted on the piston rod of the hydraulic telescopic rod 51; the direction of motion of the electric push rod 52 is perpendicular to the direction of motion of the hydraulic telescopic rod 51, and the retaining ring 53 is mounted on the push rod end of the electric push rod 52; the laser welding gun 54 is detachably mounted on the push rod end of the electric push rod 52 via the retaining ring 53.

[0022] By controlling the movements of the hydraulic telescopic rod 51 and the electric push rod 52, the height and horizontal position of the laser welding gun 54 can be adjusted to better achieve the welding of the edge strips and to complete the production of photovoltaic frames of different sizes, thus making the device more convenient to use.

[0023] like Figure 3 and Figure 4 As shown, in a preferred embodiment, the upper surface of the movable plate 2 is provided with four sliding grooves 21, which are arranged at equal intervals around the rotation axis of the movable plate 2; the clamping assembly 3 includes four clamping units, which are respectively matched with the four sliding grooves 21; the clamping unit includes a servo motor 31, a lead screw 32, a threaded sleeve 33, and a clamping plate 34; the servo motor 31 is disposed on the side wall of the movable plate 2; the lead screw 32 is rotatably disposed in the sliding groove 21, and the axis of the lead screw 32 is parallel to the long axis of the sliding groove 21; the output shaft of the servo motor 31 is connected to one end of the lead screw 32 through a coupling; the threaded sleeve 33 is screwed onto the lead screw 32, and the clamping plate 34 is connected to the top of the threaded sleeve 33.

[0024] In this embodiment, a sliding groove 21 is provided on the upper surface of the movable plate 2 as the sliding base of the clamping plate 34; multiple edge strips are placed on the movable plate 2 and their positions are adjusted. The servo motor 31 is started to drive the lead screw 32 to rotate. Since the clamping plate 34 is screwed onto the lead screw 32 through the threaded sleeve 33, the clamping plate 34 moves toward the center of the movable plate 2 during the rotation of the lead screw 32, causing the edge strips to move closer to the center of the movable plate 2. After the adjacent edge strips move closer (end to end in sequence), the welding assembly 5 is used for welding.

[0025] like Figure 4 As shown, in a preferred embodiment, the side of the clamping plate 34 facing the rotation axis of the movable plate 2 is provided with anti-slip protrusions 6. In this embodiment, the anti-slip protrusions 6 are provided on the surface of the clamping plate 34, which increases the friction when the clamping plate 34 contacts the edge strip, preventing the edge strip from sliding due to external force or vibration during the welding process.

[0026] like Figure 4 and Figure 5 As shown, in a preferred embodiment, the upper surface of the base 1 is provided with a circular mounting groove 11, and a vertical positioning shaft 12 is provided at the center of the mounting groove 11; the rotating assembly includes a drive motor 41, a driving gear 42, and a driven gear 43; the drive motor 41 is disposed on the lower surface of the base 1, and the output shaft of the drive motor 41 passes through the upper surface of the base 1 and is connected to the driving gear 42; the driven gear 43 is disposed on the lower part of the movable plate 2, and a bearing 44 is embedded in the middle of the driven gear 43; the rotation axis of the movable plate 2, the axis of the driven gear 43, and the axis of the bearing 44 coincide; the movable plate 2 is rotatably mounted on the positioning shaft 12 through the bearing 44, and the driven gear 43 meshes with the driving gear 42.

[0027] In this embodiment, a mounting groove 11 is formed on the upper surface of the base 1, and a positioning shaft 12 is set at the center of the mounting groove 11 as the mounting base for the driven gear 43. When rotation is required, the drive motor 41 is started, and the output shaft of the drive motor 41 drives the driving gear 42 to rotate. Since the driving gear 42 meshes with the driven gear 43, the driven gear 43 follows the driving gear 42 to rotate. The driven gear 43 drives the movable plate 2 to rotate, thereby adjusting the direction of the movable plate 2 and thus adjusting the joint of the upper edge strip of the movable plate 2.

[0028] Preferably, the drive motor 41 is a stepper motor, and the stepper motor rotates 90 degrees each time to ensure that each rotation of the stepper motor can drive the square frame to rotate 90 degrees through the movable plate 2, so that the next welding position of the square frame corresponds exactly to the position of the laser welding gun 54, thereby making the welding of the square frame more convenient.

[0029] The terms "connection" and "fixing" appearing in this utility model description can refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meaning of the above terms in this utility model should be understood according to the specific circumstances.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
