Description

[0096] The movable welding equipment and the welding workstation provided by the above embodiments have the following beneficial effects:

[0097] 1. Currently, the moving position of the protective equipment is single and cannot move to the welding position in time. In the embodiment of the present invention, by starting the first servo motor to drive the second pulley to rotate, the second pulley drives the first pulley to rotate through the belt, the first pulley drives the rotating rod to rotate, the second bevel gear on the rotating rod rotates, and the second bevel gear drives the first bevel gear to rotate, thereby driving the first lead screw to rotate. By rotating the first lead screw, the first sliding frame is driven to move back and forth along the X-axis direction. Starting the second servo motor drives the second lead screw to rotate, and the second lead screw drives the sliding plate to move back and forth along the Y-axis direction. Starting the third servo motor drives the third lead screw to rotate, and the third lead screw drives the first sliding block and the laser emitter to move back and forth along the Z-axis direction. While the first sliding frame and the sliding plate are moving, the laser emitter will also be driven to move. The reason for using the bevel gear to drive the first lead screw to rotate is to facilitate the synchronous rotation of the first lead screws of the two first sliding parts, so that the first sliding frame will move more stably along the X-axis direction. The laser emitter and the protective cover move together. Through the protective cover, a large amount of welding fumes can be prevented from spreading outside the device, and at the same time, the arc light generated during welding can be prevented from affecting the staff, which well solves the problem that the moving position of the protective equipment is single and cannot move to the welding position in time;

[0098] 2. Currently, the battery components are all welded manually during welding, which is time-consuming and laborious, and dust cannot be removed well during welding. In the embodiment of the present invention, through the pressing cylinder and the dust removal pressing plate, a large amount of dust generated during welding can be well prevented from spreading outside the device. The tray is lifted by an external lifting device during welding. The laser channel abuts against the battery component to be welded, and then the laser emitter moves above the laser channel to weld the battery component. The multiple suction pipes on the pressing cylinder and the dust removal pressing plate are connected to the connecting pipe, and the connecting pipe can be connected to an external dust suction device. The multiple suction pipes are used to suck the dust generated during welding, which solves the problem that the product quality qualification rate is affected due to the pollution of the pole column or the connecting piece caused by the splash of welding slag during the current welding process, which is likely to form a welding explosion point;

[0099] 3. At present, when welding battery components, battery components of different models and sizes are encountered. Since there is no distance measuring device, it is impossible to well control the movement of the laser emitter to the corresponding position after tool change, which easily leads to laser deviation. In the embodiment of the present invention, the second cylinder is started to move the L-shaped bearing plate above the battery component, and then one of the distance measuring sensors is driven to move by moving the movable block. The distance measuring sensor is moved corresponding to the battery component after tool change, and the moving distance is initially determined through the pointer and the scale. The distance measuring sensor can accurately determine the moving distance again, thus facilitating the movement of the emission laser to the corresponding position, solving the problem that when welding battery components at present, battery components of different models and sizes are encountered, and due to the absence of a distance measuring device, it is impossible to accurately control the movement of the laser emitter to the corresponding position after tool change.

[0100] 4. During welding, the welding points are confirmed manually, which is time-consuming and laborious. In the embodiment of the present invention, the camera fixing seat is fixed on the first sliding block, and when the moving mechanism moves, the CCD camera is driven to move at the same time. The CCD camera is moved above the battery component to be welded, and the position of the welding point is determined and marked through the CCD camera, solving the problem that during welding, the welding points are confirmed manually, which is time-consuming and laborious.
