Description

Technical Field

[0001] The present invention relates to the technical field of battery trays for new energy vehicles, and in particular to automated welding equipment for battery trays for new energy vehicles. Background Art

[0002] With the rapid development of new energy vehicles, batteries, as their core components, have increasingly stringent production requirements. As an important structural component that carries battery modules, battery trays not only need to bear the weight of the battery, but also need to have good strength, durability and thermal management capabilities to ensure the safe operation of the battery under various working conditions. Therefore, the manufacturing accuracy of the battery tray is directly related to the safety and life of the battery pack.

[0003] Traditional battery tray manufacturing usually adopts manual welding, which not only makes it difficult to ensure welding quality, but also has low production efficiency and cannot meet the needs of large-scale production. Manual welding relies on the experience and technical level of workers, and is easily affected by factors such as worker fatigue and mood, resulting in unstable welding quality. Insufficient welding accuracy can easily cause welding point deviation, affecting the overall strength and stability of the battery tray. In addition, manual welding has low production efficiency and is difficult to meet the efficiency requirements of modern production. In addition, due to the large uncertainty of manual welding and the high difficulty of welding quality control, the product qualification rate decreases, thereby increasing the manufacturing cost. In view of the above problems, an automated welding equipment for new energy vehicle battery trays is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the technical problems raised in the above background technology.

[0005] The present invention adopts the following technical scheme: an automated welding equipment for a new energy vehicle battery tray, comprising a base, a support frame fixedly installed on the surface of the base, an electric slide rail fixedly installed on the surface of the support frame, a slide plate slidably connected to the surface of the electric slide rail, a placement frame fixedly installed on the surface of the slide plate, a bracket fixedly installed on the bottom surface of the slide plate, a cylinder fixedly installed on the bottom surface of the bracket, a push plate fixedly installed on the output end of the cylinder, a cushion fixedly installed on the surface of the push plate, a column fixedly installed on the surface of the base, a top plate fixedly installed on the top of the column, a mounting frame fixedly installed on the bottom surface of the top plate, a mounting block arranged inside the mounting frame, a fixing plate fixedly installed on the bottom surface of the fixing block, and a welding head fixedly installed on the bottom surface of the fixing plate.

[0006] Preferably, a screw is fixedly mounted on the surface of the placement frame, a limiting plate is inserted on the surface of the screw, and a nut is threadedly connected to the surface of the screw. Here, the screw and the limiting plate are installed on the surface of the placement frame to achieve stable positioning of the battery tray in the placement frame. The limiting plate cooperates with the nut to effectively prevent the battery tray from deflecting during welding, thereby improving welding accuracy.

[0007] Preferably, the number of the limit plates is four groups, and the four groups of limit plates are symmetrically distributed on the surface of the placement frame. Here, the limit plates are symmetrically distributed to ensure the multi-directional support and balance of the tray, so that the battery tray remains stable during the welding process, effectively reducing the vibration that may be generated during the welding process, and improving the welding quality and equipment stability.

[0008] Preferably, the bottom surface of the push plate is fixedly mounted with guide rods, the guide rods are evenly distributed around the bottom surface of the push plate, and the guide rods slide inside the bracket. Here, the guide rods can slide inside the bracket, which helps the push plate to run stably, ensures the even distribution of thrust, reduces the friction loss of the device under the action of thrust, and prolongs the life of the device.

[0009] Preferably, a connecting plate is fixedly installed on the side of the column, and a baffle is fixedly installed on the surface of the connecting plate, and the baffles are symmetrically distributed on both sides of the column. Here, the connecting plate and the baffle are installed on the side of the column, which not only protects the safety of the equipment during the welding process, but also prevents the generation of spatter during the welding process under the design of left-right symmetrical distribution, thereby enhancing the safety and stability of the equipment.

[0010] Preferably, the interior of the baffle is set as a transparent plate. Here, the transparent plate allows the operator to clearly observe the welding process, ensure the welding quality, and provide a protective barrier for the welding area to avoid injuries caused by misoperation of personnel and improve safety.

[0011] Preferably, a cylinder is fixedly mounted on the side of the mounting frame, a latch is slidably connected inside the cylinder, a spring is sleeved on the surface of the latch, a plug hole is opened on the side of the mounting block, and the latch is inserted into the plug hole. Here, the mounting block can be quickly positioned and fixed, the mounting accuracy and stability of the welding head are improved, and the stability of the welding effect is ensured.

[0012] Preferably, the pin is provided with a thread groove inside, a screw is threadedly connected to the inside of the thread groove, a screw hole is provided inside the jack, and the screw is threadedly connected to the inside of the screw hole. Here, the thread groove and the screw are connected with the thread of the jack to ensure the stability of the pin and prevent it from loosening due to vibration, thereby ensuring that the welding head does not shift during high-frequency welding, and improving the reliability and welding accuracy of the equipment.

[0013] Preferably, the number of the latches is two groups, and the two groups of latches are symmetrically distributed on both sides of the installation frame. Here, the symmetrical distribution of the two groups of latches can evenly distribute the fixing force of the installation frame, ensuring that the installation frame is balanced and stable during use, while increasing the anti-deformation ability of the latches and improving the durability of the device.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are: 1. In the present invention, by adding screws and limit plates in the placement frame, the stable positioning of the battery tray is ensured, and the tray is effectively prevented from shifting during the welding process. When the welding process is completed, the electric slide rail drives the slide plate to move, and then the limit plate is removed. At this time, the cylinder drives the push plate to move upward, and the push plate drives the soft pad to lift the tray, so that the tray can be pushed out from the inside of the placement frame so that personnel can remove the tray.

[0015] 2. In the present invention, the safety and stability of the equipment are improved by symmetrically installing connecting plates and transparent baffles on both sides of the column. The transparent baffle can not only effectively prevent the spatters generated during the welding process from damaging the equipment and operators, but also enable the operators to observe the welding process in real time to ensure the welding quality. While increasing safety protection, it also improves the controllability and observation convenience of the welding operation, avoiding safety problems caused by misoperation.

[0016] 3. In the present invention, the combined structure of the pin, the cylinder and the spring enables the welding head to be quickly positioned, which is convenient for stable operation in high-frequency welding operations. In addition, the threaded groove and screw connection design of the pin prevent loosening caused by vibration during welding, thereby improving the reliability of welding.
