Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be clearly and completely described below with reference to the detailed description of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
For convenience in explanation, the description herein uses terms indicating relative spatial positions, such as "upper," "lower," "rear," "front," and the like, to describe one element or feature's relationship to another element or feature as illustrated in the figures. The term spatially relative position may encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "above" other elements or features would then be oriented "below" or "above" the other elements or features. Thus, the exemplary term "below" can encompass both a spatial orientation of below and above.
Fig. 1 is a schematic view of a battery case laser welding tool according to the present invention, and fig. 1 is a drawing. The battery case laser welding tool 1 includes a frame 2, a positioning mechanism 3, and a welding mechanism (not shown). A positioning mechanism 3 is provided on the frame 2 to position the battery compartment. The welding mechanism is arranged on the frame 2, and the battery box is welded after being positioned by the positioning mechanism 3. That is, the positioning mechanism 3 and the welding mechanism are provided on the frame 2, and after the battery case is automatically or manually clamped by the positioning mechanism 3, the welding mechanism is moved to the battery case for welding.
The structure and the operation principle of the frame 2 and the positioning mechanism 3 will be described in detail below.
The frame 2 includes a base 21, a leveling mechanism 22, a communication system 23, and an air supply control system 24. The positioning mechanism 3 is mounted on the base 21 in a seated position. The horizontal adjusting mechanism 22 is disposed under the plurality of legs of the base 21 to keep the base 21 horizontal, and generally, the number thereof is determined according to the number of the legs of the base 21, and as shown in fig. 1, the number thereof is 4, but not limited thereto. The communication system 23 collects and relays signals to and from the inside of the tool 1, such as a horizontal adjustment signal, a clamping control signal of the positioning mechanism 3, an input welding start signal, an output welding end signal, a control signal of the PLC, and the like. Air supply control system 24 distributes and controls the output of the air supply.
The positioning mechanism 3 includes a clamp positioning mechanism 31, a dead point positioning mechanism 32, a splash guard mechanism 33, and a double-rail positioning mechanism 34.
As shown in fig. 2, the clamping and positioning mechanism 31 has a plurality of pressing points 311 and pressing arms 312, for example, 3, as required. In this embodiment, the gap between the plurality of pinch points is 5 mm. So, only remain 5mm clearance between each compress tightly the point, many compress tightly the point of equipartition again, even laser welding process can produce a large amount of heats, also can guarantee at the welded in-process, the faying face between the product is enough flat, is favorable to the going on smoothly of welding.
However, in the welding process, a large reaction force is generated due to the deformation of the product, and at the moment, the positioning reference needs to overcome the influence of the action force caused by the deformation so as to control the deformation of the product.
In the present embodiment, as shown in fig. 3 and 4, the dead point positioning mechanism 32 includes a positioning support block 321, a stopper 322 and a spring 323, the positioning support block 321 abuts against the pressing point 311 of the clamping and positioning mechanism 31, one side of the stopper 322 abuts against the positioning support block 321 and the stopper 322 has a dead point, for example, the stopper 322 is a wedge-shaped block, and the spring 323 is disposed on the other side of the stopper 322. By setting the dead point reference position (the position when the stop block 322 reaches the dead point) after the positioning reference reaches the extension position, the middle wedge-shaped block is clamped to the position, and the dead point is not moved by the dead point, so that the displacement of the product in the positioning welding process is eliminated, and the dimensional accuracy of the product after the laser welding is finished is ensured.
In the welding process, the coating on the surface of a product (battery box) is heated and can be volatilized in a large quantity, and splashed dust can cover the surface of the product to form a plugging hole. In order to prevent the occurrence of the blocking phenomenon, in the present embodiment, as shown in fig. 5, the splash guard 331 is added to the splash guard mechanism 33 of the positioning mechanism 3 outside the water nozzle of the tool 1, and the pressing arm 332 is opened in advance when the welding mechanism is welded to the close position through the PLC program control, so as to ensure that the welding splash cannot enter the water nozzle hole, that is, when the welding mechanism starts welding, the splash guard mechanism 33 opens the pressing arm 332 at the position corresponding to the splash guard 331, and the opening of the pressing arm 332 is controlled by the PLC program for the tool 1. The design that frock 1 increased protection mechanism 33 that splashes can realize dirt-proof demand, increases the life of equipment and guarantees the welding quality of battery case.
In order to press the battery box in cooperation with the pressing points 311, as shown in fig. 6, a plurality of dual-rail positioning mechanisms 34 are further disposed on the base 21, each dual-rail positioning mechanism 34 includes two rails 341 and a locking mechanism 342, and the dual-rail positioning mechanism 34 lifts the positioning surface of the base 21 through the dual-rail 341, so that the positioning surface and the plurality of pressing points 311 clamp the battery box to be welded. The double-guide-rail mode can ensure the stability of lifting and the high precision of positioning.
In conclusion, the battery box laser welding tool disclosed by the invention can realize that the battery box can be kept flat before welding or in the welding process through the design of the positioning mechanism, and is high in positioning precision and high in welding quality. Furthermore, through the design of the splash protection mechanism, the dustproof requirement can be met, the service life of the equipment is prolonged, and the welding quality of the battery box is guaranteed.
