Description

Technical Field

[0001] This utility model relates to the field of laser welding equipment technology, and in particular to a multi-station welding workbench for a laser welding machine. Background Technology

[0002] In modern industrial production, laser welding technology is widely used in many fields such as electronics, automobiles, and medical devices due to its advantages such as high welding precision, high speed, and small heat-affected zone. The worktable of the laser welding machine, as a key component for supporting and positioning the workpiece, directly affects welding efficiency and quality. However, in the existing technology, traditional laser welding worktables are mostly designed as single-station machines, meaning that only one workpiece can be welded at a time. In actual production, this type of single-station machine has obvious limitations: when welding, the operator must wait for the current workpiece to be welded before the next workpiece can be loaded, positioned, and welded. Throughout the process, the laser welding machine has a lot of idle time, resulting in low production efficiency and difficulty in meeting the needs of mass production. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the prior art by proposing a multi-station welding workbench for laser welding machines.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a multi-station welding workbench for a laser welding machine, comprising a workbench body and a laser welding mechanism, wherein a control system is installed at the front end of the workbench body, a rotary table is provided above the workbench body, a fixed base is fixedly installed at the top inside the workbench body, a variable speed motor is installed at one end of the fixed base, a rotating shaft is also rotatably installed through the upper end of the workbench body, and an angle sensor is installed at the front end of the rotary table.

[0005] Preferably, the upper end of the rotating shaft is fixed to the lower end of the rotary table, and the lower end of the rotating shaft is fixed to the output end of the variable speed motor.

[0007] Preferably, a ring seat is installed at the upper end of the worktable body, and multiple sets of stabilizing columns are installed at the lower end of the rotary table.

[0008] Preferably, the upper end of the annular seat is provided with a circular groove, and the lower parts of the multiple sets of stabilizing columns are all disposed inside the circular groove.

[0009] Preferably, a front-to-back moving mechanism is installed on the upper end of the workbench body, a left-to-right moving mechanism is installed on the movable end of the front-to-back moving mechanism, one end of the laser welding mechanism is fixed to the movable end of the left-to-right moving mechanism, and the front-to-back moving mechanism, the left-to-right moving mechanism and the laser welding mechanism are all connected to the control system signal.

[0010] Preferably, a feeding mechanism is installed at the upper end of the workbench body, and the feeding mechanism is connected to the control system signal.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, a variable speed motor, in conjunction with a rotating shaft, drives the rotary table to rotate. An angle sensor can accurately feedback the angle information of the rotary table, ensuring accurate switching of the rotary table's workstations and making the workpiece positioning at the welding station more accurate. With the help of four sets of clamping mechanisms, while the laser welding mechanism is welding a workpiece at one workstation, other workstations can simultaneously perform operations such as loading, greatly reducing equipment downtime and significantly improving production efficiency. In addition, multiple sets of stabilizing columns at the lower end of the rotary table slide within the circular grooves of the annular seat, effectively enhancing the stability of the rotary table during rotation and preventing the workpiece from shaking during the welding process, thus ensuring the consistency and strength of the weld.

[0012] 2. In this utility model, with the cooperation of the front-back moving mechanism, the left-right moving mechanism and the laser welding mechanism, the laser welding mechanism can flexibly adjust its position under the drive of the front-back moving mechanism and the left-right moving mechanism, which can adapt to the welding requirements of workpieces of different sizes, further enhancing the versatility and flexibility of the equipment and improving the utilization rate of the equipment. 2. In this utility model, the operation of the entire equipment is centrally controlled by the control system. Operators only need to make simple parameter settings and issue commands through the control system to realize the automated operation of the equipment, which simplifies the operation process. At the same time, the unloading mechanism realizes the automatic unloading of the workpiece after welding, reducing manual intervention and reducing the labor intensity of operators.

Detailed Implementation

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a multi-station welding workbench for a laser welding machine, including a workbench body 1 and a laser welding mechanism 6. A control system 2 is installed at the front end of the workbench body 1, and a rotary table 3 is arranged above the workbench body 1. A fixed seat 9 is fixedly installed at the top inside the workbench body 1, and a variable speed motor 10 is installed at one end of the fixed seat 9. A rotating shaft 11 is also rotatably installed through the upper end of the workbench body 1. An angle sensor 14 is installed at the front end of the rotary table 3. The upper end of the rotating shaft 11 is fixed to the lower end of the rotary table 3, and the lower end of the rotating shaft 11 is fixed to the output end of the variable speed motor 10. Four sets of detachable clamping mechanisms 8 are installed at the upper end of the rotary table 3. The four sets of clamping mechanisms 8, the angle sensor 14, and the variable speed motor 10 are all connected to the control system 2. A circular seat 12 is installed at the upper end of the workbench body 1, and multiple sets of stabilizing columns 13 are installed at the lower end of the rotary table 3. A circular groove 15 is opened at the upper end of the circular seat 12, and the lower parts of the multiple sets of stabilizing columns 13 are all arranged inside the circular groove 15.

[0018] The specific settings and functions of this embodiment are described below. The workbench body 1 serves as the basic load-bearing component of the entire equipment, providing an installation and support platform for other components. A control system 2 is installed at its front end. The control system 2 is the core control hub of the equipment, responsible for coordinating and controlling the operation of various mechanisms. A rotary table 3 is set above the workbench body 1. The rotary table 3 is a key component for realizing multi-station conversion, used to carry the workpiece to be welded and drive it to switch between different stations. A fixed base 9 is fixedly installed at the top of the inside of the workbench body 1. The fixed base 9 provides a stable mounting foundation for the variable speed motor 10, ensuring that the variable speed motor 10 will not shake during operation. The variable speed motor 10 is installed at one end of the fixed base 9. The variable speed motor 10 provides power for the rotation of the rotary table 3, and it can meet the rotation speed requirements of the rotary table 3 under different working conditions by changing the output speed. A rotating shaft 11 is rotatably installed through the upper end of the workbench body 1. The rotating shaft 11 serves to connect the variable speed motor 10 and the rotary table 3. Its upper end is fixed to the lower end of the rotary table 3, and its lower end is fixed to the output end of the variable speed motor 10. In this way, when the variable speed motor 10 is working, it can drive the rotary table 3 to rotate synchronously through the rotating shaft 11. An angle sensor 14 is installed at the front end of the rotary table 3. The angle sensor 14 can monitor the rotation angle of the rotary table 3 in real time and transmit the monitored signal to the control system 2 so that the control system 2 can accurately control the rotation position of the rotary table 3. A ring seat 12 is installed at the upper end of the worktable body 1, and multiple sets of stabilizing columns 13 are installed at the lower end of the rotary table 3. A circular groove 15 is opened at the upper end of the ring seat 12, and the lower parts of the multiple sets of stabilizing columns 13 are all set inside the circular groove 15. When the rotary table 3 rotates, the stabilizing columns 13 will slide in the circular groove 15, and together with the ring seat 12, they will provide stable support for the rotary table 3, effectively preventing the rotary table 3 from tilting or shaking during rotation, and ensuring the smooth operation of the rotary table 3. Four sets of detachable clamping mechanisms 8 are installed on the upper end of the rotary table 3. The four sets of clamping mechanisms 8 are evenly distributed on the rotary table 3 and are used to clamp and fix different workpieces to be welded. The four sets of clamping mechanisms 8, angle sensor 14 and variable speed motor 10 are all connected to the control system 2. The control system 2 can control the start, stop and speed of variable speed motor 10 according to the signal fed back by angle sensor 14, thereby controlling the rotation of rotary table 3. At the same time, it can also control the clamping action of clamping mechanism 8 to realize automated operation.

[0019] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, a front-to-back moving mechanism 4 is installed on the upper end of the workbench body 1. A left-to-right moving mechanism 5 is installed on the movable end of the front-to-back moving mechanism 4. One end of the laser welding mechanism 6 is fixed to the movable end of the left-to-right moving mechanism 5. The front-to-back moving mechanism 4, the left-to-right moving mechanism 5 and the laser welding mechanism 6 are all connected to the control system 2. A feeding mechanism 7 is installed on the upper end of the workbench body 1. The feeding mechanism 7 is connected to the control system 2.

[0020] The overall effect of this embodiment is that a front-to-back moving mechanism 4 is installed on the upper end of the workbench body 1. The front-to-back moving mechanism 4 can drive the connected parts to move in the front-to-back direction. A left-to-right moving mechanism 5 is installed on the movable end of the front-to-back moving mechanism 4. The left-to-right moving mechanism 5 can be driven by the front-to-back moving mechanism 4 and can also drive the connected parts to move in the left-to-right direction. One end of the laser welding mechanism 6 is fixed to the movable end of the left-to-right moving mechanism 5. Under the coordinated action of the front-to-back moving mechanism 4 and the left-to-right moving mechanism 5, the laser welding mechanism 6 can realize the movement in the front-to-back and left-to-right directions, thereby accurately aligning the workpiece rotated to the welding station for welding operations. Furthermore, the front-to-back moving mechanism 4, the left-to-right moving mechanism 5 and the laser welding mechanism 6 are all signal connected to the control system 2. The control system 2 can accurately control their movement trajectory and working status. The upper end of the workbench body 1 is equipped with a feeding mechanism 7. The feeding mechanism 7 is connected to the control system 2. After the workpiece is welded, the rotary table 3 rotates it to the feeding station. Under the control of the control system 2, the feeding mechanism 7 automatically feeds the welded workpiece, realizing the closed loop of the automated production process.

[0021] The operation and working principle of this device are as follows: Before starting work, the operator presets the relevant parameters in the control system 2, including the rotation angle of the rotary table 3, the clamping force of the clamping mechanism 8, the welding parameters of the laser welding mechanism 6, the movement trajectory of the forward and backward moving mechanism 4 and the left and right moving mechanism 5, and the timing of the action of the unloading mechanism 7. The first stage is the loading stage. The operator places the workpiece to be welded in the empty clamping mechanism 8 on the rotary table 3. After the control system 2 receives the signal that the loading is completed (which can be triggered manually or detected by a sensor), it controls the clamping mechanism 8 to move and stably clamp the workpiece to prevent displacement during subsequent rotation and welding. Next, the control system 2 sends a command to the variable speed motor 10, the variable speed motor 10 starts and drives the rotary table 3 to start rotating through the rotating shaft 11. During the rotation of the rotary table 3, the angle sensor 14 at its front end detects the rotation angle of the rotary table 3 in real time and continuously feeds the angle information back to the control system 2. When the rotary table 3 rotates to the preset angle, so that the clamping mechanism 8 with the workpiece to be welded accurately reaches the welding station, the control system 2 controls the variable speed motor 10 to stop running and the rotary table 3 remains stationary. At this time, the control system 2 controls the front-to-back moving mechanism 4 and the left-to-right moving mechanism 5 to start. The two work together to move the laser welding mechanism 6 to the workpiece above the welding station and adjust it to a suitable welding position. Then, the laser welding mechanism 6 starts under the control of the control system 2 and performs welding operations on the workpiece according to the preset welding parameters. During the welding process, if the workpiece needs to be welded at multiple angles, the control system 2 can control the front-to-back moving mechanism 4 and the left-to-right moving mechanism 5 to move the laser welding mechanism 6 according to the preset program, or control the variable speed motor 10 to drive the rotary table 3 for fine adjustment to ensure the accuracy of the welding process. Finally, once the workpiece at one station is welded, the control system 2 stops the laser welding mechanism 6 and moves it away from the station via the forward / backward movement mechanism 4 and the left / right movement mechanism 5. Simultaneously, the control system 2 restarts the variable speed motor 10, causing the rotary table 3 to continue rotating, moving the next clamping mechanism 8 containing the workpiece to be welded to the welding station, repeating the welding process. The welded workpiece is then transported to the unloading station as the rotary table 3 rotates. When the welded workpiece arrives at the unloading station, the control system 2 controls the unloading mechanism 7 to start. The unloading mechanism 7 performs operations such as grabbing or pushing the workpiece to remove it from the clamping mechanism 8, thus completing the unloading process. At the same time, the control system 2 controls the clamping mechanism 8 at this station to release so that it can be loaded again later.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
