Description

Technical Field

[0001] This utility model relates to the technical field of welding equipment, specifically to a double-sided welding and flipping mechanism for photovoltaic panels. Background Technology

[0002] Automated welding equipment is a machine that can weld objects through system control, effectively improving production efficiency and reducing production costs. However, existing automated welding machines generally use partial clamping or positioning structures to fix products, which can easily damage brittle semiconductor wafers due to clamping forces during positioning and welding. Furthermore, positioning structures such as grooves cannot allow for flipping. When welding two sheet-like plates together via electrodes, it is generally necessary to weld one side of the plate to the electrode first, then flip the product to weld the other side. This prevents rapid automatic flipping when welding two brittle products. For example, in a radioisotope battery, when welding two semiconductor silicon wafers together via electrodes, currently only one semiconductor wafer can be welded to the electrode first, and then the other semiconductor wafer is installed before welding. While this achieves automated welding, the welding efficiency is low, and operators cannot simultaneously load products during the welding process. Summary of the Invention

[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a photovoltaic panel double-sided welding and flipping mechanism, which can ensure the integrity of the fixed surface of brittle materials during the welding process, enable the double-sided materials to be flipped quickly during welding, and achieve the purpose of synchronous material filling during the welding process, resulting in high production efficiency.

[0004] To address the aforementioned technical problems, the objective of this application is achieved through the following technical solution: A photovoltaic panel double-sided welding flipping mechanism includes a rotating component, at least two flipping components disposed on the rotating component, and a positioning component disposed on the flipping component for fixing the product to be welded.

[0005] Preferably, the positioning component includes a limiting seat fixed at one end to the flipping component, positioning grooves provided on the upper and lower sides of the limiting seat, and a pressure plate detachably provided on the positioning groove.

[0006] Preferably, the limiting seat includes a U-shaped frame, a limiting groove disposed inside the U-shaped frame, and a pressure block disposed at the open end of the U-shaped frame.

[0007] Preferably, the pressure plate and / or the positioning groove are provided with magnetic blocks.

[0008] Preferably, the rotating assembly includes a control motor, a rotary table mounted on the control motor, and a mounting base mounted on the rotary table, and the flipping assembly is mounted on the mounting base.

[0009] Preferably, the mounting base has a T-shaped structure, and two flipping components are used and installed on both sides of the mounting base.

[0010] Preferably, the rotary table includes a base, a turntable mounted on the base and controlled to rotate by the control motor, a position sensor on the base, and a positioning block on the turntable.

[0011] Preferably, the flipping assembly is a rotary cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: First, by combining the rotating component and multiple flipping components with positioning components, double-sided welding products can be automatically flipped during welding. At the same time, during the welding process, operators can promptly remove the welded products and load products to be welded, thus effectively solving the problem that existing welding equipment cannot easily load and complete double-sided welding in one go, effectively improving welding efficiency and production efficiency.

[0013] Secondly, the pressure plate adopts magnetic connection, which can ensure that the wafer semiconductor silicon wafer will not have excessive local stress during clamping, and will not fall or shift during rotation. This can effectively avoid damage to thin and brittle semiconductor wafers during welding due to unreasonable clamping structure design. Attached Figure Description

[0015] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0016] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0017] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0018] like Figure 1 and 2 As shown, a photovoltaic panel double-sided welding flipping mechanism includes a rotating component 1, at least two flipping components 2 disposed on the rotating component 1, and a positioning component 3 disposed on the flipping component 2 for fixing the product to be welded.

[0019] In actual operation, the double-sided welding flipping mechanism is installed on the operating table of the automatic welding machine through the rotating component 1. The rotating component 1 can rotate and switch the relative positions of multiple flipping components 2, so that at least one of them is located in the welding area and the other is located in the external filling and feeding area. During operation, the operator installs the product onto the external positioning component 3, and then rotates the rotating component 1 to rotate the positioning component 3 with the product installed to the welding area for welding the upper surface. At the same time, the operator installs the product onto the outer positioning component 3. After one side of the product is welded, the system controls the flipping component 2 to rotate 180° to weld the other side. The outer product can also be assembled separately by rotation during installation. After both sides are welded, the rotating component 1 rotates again to remove the welded product from the welding area, and the newly loaded product enters the welding area for welding. The welded product rotated to the loading area can be disassembled. Through the combination of the rotating component 1 and multiple flipping components 2 with positioning components 3, the double-sided welded product can be automatically flipped during welding. At the same time, during the welding process, the operator can promptly remove the welded product and load the product to be welded, thus effectively solving the problem that existing welding equipment cannot easily achieve double-sided direct welding in one loading, effectively improving welding efficiency and production efficiency.

[0020] A further improvement is that the positioning component 3 includes a limiting seat 31 with one end fixed to the flipping component 2, positioning grooves 32 provided on the upper and lower sides of the limiting seat 31, and a pressure plate 33 detachably provided on the positioning grooves 32.

[0021] The product body with welding and the metal electrode sheet penetrating the upper and lower semiconductors are fixed by the limiting seat 31. The wafer-shaped semiconductor silicon wafers on the upper and lower sides are specifically pressed and limited by the pressure plates 33 on both sides. This can ensure that the wafer-shaped semiconductor silicon wafers will not form excessive local stress during the clamping process, and will not fall or shift during the rotation process. It can effectively avoid the phenomenon that the thin and brittle semiconductor wafers will be damaged during the welding process due to unreasonable clamping structure design.

[0022] A further improvement is made to the limiting seat 31, which includes a U-shaped frame 321, a limiting groove 322 disposed inside the U-shaped frame 321, and a pressure block 323 disposed at the opening end of the U-shaped frame 321.

[0023] After the main body of the product to be welded slides into the limiting groove 322, it is engaged in the U-shaped frame 321. The pressure block 323 at the open end can press the product firmly, thereby ensuring the relative position accuracy of the product and effectively preventing displacement of the product after installation. At the same time, by pressing the inner and outer sides of the product, a relative positioning can be formed between the conductive metal parts to be welded and the product, preventing the conductive metal parts from falling off or shifting due to lack of pressure.

[0024] For example, when welding the semiconductor silicon wafers and electrode sheets on both sides of the battery body, after the battery body slides in through the limiting groove 322, the outer end is pressed by the pressure block 323. At the same time, the metal electrode sheets located on the side of the battery body are pressed and limited by the side of the U-shaped frame 321 and the pressure block 323. After inserting the battery body, if the semiconductor silicon wafer is independent, the semiconductor silicon wafer facing upward is installed first and pressed by the pressure plate 33. Then, the semiconductor silicon wafer on the other side is installed after rotating the limiting seat 31 and pressed by the pressure plate 33, thereby achieving the initial assembly and positioning of the product. Finally, the welding operation is performed by rotating the assembly and rotating the welding area.

[0025] A further improvement is that a magnetic block 4 is provided in the pressure plate 33 and / or the positioning groove 32.

[0026] When the pressure plate 33 presses and limits the upper and lower sides of the product, after the pressure plate 33 is placed, it is magnetically attracted to the positioning groove 32 by the magnetic block 4. The selection of the magnet effectively ensures the clamping force, and also makes disassembly more convenient. This effectively solves the problem that existing clamping structures require additional fixing with screws or clips, which makes product disassembly and assembly troublesome.

[0027] A further improvement based on any of the above embodiments is that the rotating assembly 1 includes a control motor 11, a rotating table 12 disposed on the control motor 11, and a mounting base 13 disposed on the rotating table 12, and the flipping assembly 2 is disposed on the mounting base 13.

[0028] When the rotating component 1 rotates the flipping component 2, the control motor 11 drives the rotating table 12 to rotate at a fixed angle, thereby realizing the fixed angle rotation of the flipping component 2 installed on the mounting base 13. The structure is simple, all components can be directly purchased, the manufacturing cost is low, and the rotation angle control is convenient.

[0029] A further improvement is made in that the mounting base 13 adopts a T-shaped structure, and two flipping components 2 are used and installed on both sides of the mounting base 13.

[0030] Mounting base 13 adopts a T-shaped structure, and its bottom is fixed to the rotating table 12 by bolts. The structure is simple, and two flipping components 2 are symmetrically installed on both sides of mounting base 13, which enables the flipping components 2 to quickly switch between the welding area and the filling area. The whole structure is simple and easy to operate.

[0031] The rotating platform 12 includes a base 121 and a turntable 122 mounted on the base 121 and controlled to rotate by the control motor 11. The base 121 is equipped with a position sensor 5 and the turntable 122 is equipped with a positioning block 6. The flipping assembly 2 is a rotary cylinder.

[0032] Mounting base 13 is fixed on turntable 122, which rotates. After installation, the initial position between base 121 and turntable 122 is corrected by the cooperation of position sensor 5 and positioning block 6. After correction, the turntable 122 can be rotated at a fixed angle simply by controlling control motor 11. At the same time, the positioning block 6 can be corrected once after passing position sensor 5, thus avoiding the problem of angular deviation between base 121 and turntable 122 during operation. Positioning component 3 is installed on piston rod of rotary cylinder, making operation simpler and faster when flipping is required, and providing high positioning accuracy.

[0033] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
