Description

Technical Field

[0001] This utility model relates to the field of laser welding technology, and more specifically, to a multi-station laser welding device. Background Technology

[0002] In modern manufacturing, laser welding technology is widely used in many fields due to its significant advantages such as high precision, high speed, and small heat-affected zone.

[0003] Traditional laser welding equipment typically employs a single-station design, meaning it can only weld one workpiece at a time. After welding a workpiece, the equipment must be stopped, the finished workpiece removed, and a new workpiece loaded before the equipment can be restarted for the next welding operation. This operating mode results in significant idle time for the equipment, hindering production efficiency. Therefore, we propose an improvement: a multi-station laser welding device.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] For an example, please refer to... Figures 1-6 A multi-station laser welding device includes a cabinet 1, a robot arm 5 is provided on the top of the cabinet 1, the robot arm 5 is connected to a laser welder 501, and two workpiece platforms 2 are also provided on the top of the cabinet 1 respectively located on both sides of the robot arm 5. The workpiece platform 2 includes a driving component provided on the cabinet 1, and the driving component is connected to a workpiece fixing part.

[0030] The workpiece fixing part includes a base plate 203 connected to the driving component. A number of support rods 204 are connected to the top of the base plate 203. A top plate 205 is connected between the top ends of the support rods 204. Fixing components are provided on the side of the top plate 205. The support rods 204 are fixed to the top plate 205 and the base plate 203 by bolts.

[0031] The setup of two workpiece platforms 2 provides two processing positions, enabling parallel processing and loading / unloading operations. While the laser welder 501 is welding a workpiece at one workpiece platform 2, the operator can load and unload workpieces at the other workpiece platform 2. This parallel operation mode greatly reduces the idle time of the device, allowing the device to complete welding tasks for more workpieces per unit time, thereby significantly improving overall production efficiency.

[0032] Furthermore, the fasteners include a mounting base 206 disposed on the side of the top plate 205 and a first cylinder 207. The piston rod of the first cylinder 207 is hinged to a pressure plate 208, and a connecting plate 210 is hinged between the pressure plate 208 and the mounting base 206. During the extension and retraction of the piston rod of the first cylinder 207, it can drive the pressure plate 208. When the pressure plate 208 rotates and stands upright, it can fix the workpiece. When the pressure plate 208 rotates toward the center area of ​​the top plate 205, it can clamp the workpiece. The first cylinder 207 and the mounting base 206 are connected to the top plate 205 by bolts.

[0033] Furthermore, the driving component includes a motor 215 mounted on the side of the cabinet 1. The output shaft of the motor 215 is connected to a lead screw 212 via a coupling. Two slides 213 are threaded onto the outer surface of the lead screw 212, and the slides 213 are disposed on the outer surface of the lead screw 212. A lead screw nut is disposed between the slides 213 and the lead screw 212. The motor 215 can drive the lead screw 212 to rotate. During the rotation of the lead screw 212, it can drive the slides 213 to move horizontally, thereby driving the base plate 203 to move horizontally to adjust the position of the base plate 203.

[0034] Furthermore, the outer surface of the lead screw 212 is connected to two bearing seats 211 by bearings, and both bearing seats 211 are installed on the top of the cabinet 1. The bearing seats 211 can support the lead screw 212 and are connected to the cabinet 1 by bolts.

[0035] Furthermore, a slide rail 201 is installed on the top of the cabinet 1, and a slider 202 is slidably connected to the slide rail 201. The slider 202 is connected to the bottom of the base plate 203. The slide rail 201 is installed on the top of the cabinet 1 by bolts. The slide rail 201 and the slider 202 cooperate with each other to support and limit the base plate 203, so as to improve the stability of the horizontal movement of the base plate 203.

[0036] Furthermore, each of the two slides 213 is provided with a baffle 214 on its side. Each of the two baffles 214 is provided with a positioning element on the side that is far away from each other, and the positioning element is located on the top of the cabinet 1. The positioning element includes a support base 4 installed on the top of the cabinet 1. The support base 4 is provided with a hydraulic buffer 401 and a sensor 402. The hydraulic buffer 401 can buffer the baffle 214 to prevent the baffle 214 from directly contacting the sensor 402. The sensor 402 is used to detect the position of the baffle 214 to confirm whether the base plate 203 has moved into place.

[0037] Furthermore, an isolator is installed on the top of the cabinet 1, which divides the top of the cabinet 1 into a processing area and a loading and unloading area. A protective box 101 is set on the top of the cabinet 1 in the processing area, and the robot arm 5 is located inside the protective box 101. The processing area is separated by the isolator and the robot arm 5 to improve the safety during the processing.

[0038] Furthermore, the isolation component includes a support frame 3 installed on the top of the cabinet 1. Two protective plates 301 are installed on the front of the support frame 3, and a support plate 302 is provided on the back of the support frame 3. Two second cylinders 303 are installed on the support plate 302. The bottom end of the piston rod of each of the two second cylinders 303 is connected to a partition plate 304. The positions of the two partition plates 304 correspond to the positions of the two workpiece platforms 2, respectively. The second cylinders 303 can drive the partition plates 304 to rise and fall, so as to control the opening and closing of the partition plates 304.

[0039] Furthermore, a wheel frame 305 is provided on the side of the partition 304, and a roller 306 is connected to the wheel frame 305. The outer surface of the roller 306 is in rolling contact with the support frame 3. The roller 306 can cooperate with the support frame 3 to limit the partition 304, so as to improve the stability of the partition 304 lifting and lowering.

[0040] The support plate 302 and the guard plate 301 are both connected to the support frame 3 by bolts. The support frame 3 is installed on the top of the cabinet 1 by bolts. The second cylinder 303 is connected to the support plate 302 by bolts.

[0041] This application is also equipped with a PLC control system. The robot arm 5, motor 215, second cylinder 303, first cylinder 207 and sensor 402 are all controlled by the PLC control system. The PLC control system is existing technology, and its control principle and circuit connection are also existing technology, which will not be described in detail in this application.

[0042] In use, the second cylinder 303 drives the partition 304 to rise, and then the motor 215 drives the lead screw 212 to rotate, so as to drive the base plate 203 to move through the slide 213, so that the base plate 203 moves from the processing area to the loading and unloading area. The first cylinder 207 drives the pressure plate 208 to rotate and stand up, so as to take out the processed workpiece from the top of the top plate 205, and then put in the workpiece to be processed. The first cylinder 207 drives the pressure plate 208 to rotate toward the workpiece to clamp the workpiece, and then the base plate 203 moves to the processing area, and the second cylinder 303 drives the partition 304 to fall.
