[0023] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this utility model provides a technical solution: a metal frame welding device, comprising: an equipment base 1, with conveyors installed at both ends of the equipment base 1; the equipment base 1 is a U-shaped metal frame; support platforms 2 are bolted to both ends of the top of the equipment base 1, forming a welding channel between the two support platforms 2; a material trough 6 is welded inside the equipment base 1, with a material placement port at one end of the material trough 6 and a feeding part installed on one side of the material trough 6 for feeding materials one by one into the support platforms 2. At the top of the support platform 2, a transmission belt assembly 18 for driving material docking is installed; a limiting structure is placed at the top of the support platform 2, and the limiting structure includes a limiting rod 11 and a limiting rod 2 15. Both the limiting rod 11 and the limiting rod 2 15 are fixedly connected to the support platform 2. A pressure plate 12 for pressing the material is raised and lowered in the middle of the limiting rod 11. A double-axis cylinder 2 14 for lifting the material is provided between the limiting rod 2 15 and the limiting rod 11; two laser welding heads 5 are provided and are symmetrically arranged up and down along the welding channel.

[0025] It should be noted that in this embodiment, a controller and an operation panel are provided. The workpiece at a 45-degree angle at the end is placed in the material trough 6. During operation, the feeding part conveys the material upward, thereby conveying the material to the top of the support platform 2. The transmission belt assembly 18 pushes the workpiece forward, thereby pushing the workpiece between the first limit rod 11 and the second limit rod 15, so that the ends of the two workpieces are joined together. The pressure plate 12 presses it down to fix it. The controller controls the laser welding head 5 to move towards the workpiece and weld the joint of the workpiece along the welding channel. Under the action of the timer, the laser welding head 5 and the pressure plate 12 are reset. The dual-axis cylinder 14 lifts the welded material, and then the unloading cylinder 9 pushes the material to the conveyor belts at both ends for conveying.

[0026] In one embodiment, the feeding unit includes a linear module 2 7 fixedly connected to one side of the material trough 6. The material trough 6 is slidably connected to the feeding plate 8. The movable slide of the linear module 2 7 is fixedly connected to the feeding plate 8. The material trough 6 corresponding to the support platform 2 is provided with a feeding hole for material to pass through.

[0027] It should be noted that in this embodiment, the linear module 2 7 drives the feeding plate 8 to move upward. This pushes the workpiece at the top out of the feeding hole, making its bottom parallel to the top of the support platform 2. An infrared sensor is installed on the top of the equipment base 1 to detect whether the top of the material at the top has reached the preset position. When the linear module 2 7 pushes the material through the feeding plate 8, the infrared sensor detects the material information and sends a signal to the controller. The controller controls the linear module 2 7 to stop working and controls the transmission belt assembly 18 to push the material to the designated position.

[0028] In one embodiment, the transmission belt assembly 18 includes a transmission belt, two pulleys mounted at both ends of the transmission belt, a housing for supporting the pulleys, and a motor for driving the pulleys. A pusher plate 20 is fixedly connected to the outer side of the transmission belt, and a conveying channel 16 is installed on the top of the conveying hole. A groove for the pusher plate 20 to pass through is opened on one side of the conveying channel 16. A dual-axis cylinder 3 17 is fixedly connected to the top of the support platform 2, and the output end of the dual-axis cylinder 3 17 is fixedly connected to the housing.

[0029] It should be noted that, in this embodiment, when pushing the material, after the controller receives the signal from the infrared sensor that the material has reached the corresponding height, the controller controls the dual-axis cylinder 17 to drive the housing forward, so that the transmission belt is located on the side close to the material. The motor drives the transmission belt and pulley to move inside the housing. The transmission belt drives the pusher plate 20 to push the material from one end along the length of the material in the conveying channel 16 towards the space between the limit rod 11 and the limit rod 25. An infrared sensor for detecting the position of the pusher plate 20 is installed at the top of one end of the housing. When the pusher plate 20 corresponds to the infrared sensor, the material is pushed to the designated position. At this time, the two materials are joined together. The dual-axis cylinder 17 drives the housing to retract and separate the pusher plate 20 from the workpiece. After separation, the pusher plate 20 rotates once inside the housing under the drive of the motor and then resets.

[0030] In one embodiment, the channel between the second limiting rod 15 and the first limiting rod 11 corresponds to the conveying channel 16. A double-axis cylinder 19 is fixedly connected to the top of the support platform 2 and to one side of the first limiting rod 11. The output end of the double-axis cylinder 19 is fixedly connected to the pressure plate 12. A lifting groove 13 for sliding the pressure plate 12 is provided in the middle of the first limiting rod 11.

[0031] It should be noted that in this embodiment, when the infrared sensor detects that the pusher plate 20 has reached the designated position, the controller controls the dual-axis cylinder three 17 to work while controlling the dual-axis cylinder four 19 to drive the pressure plate 12 to move downward along the lifting groove 13, thereby pressing the workpiece between the limit rod one 11 and the limit rod two 15 through the pressure plate 12, thereby fixing the workpiece.

[0032] In one embodiment, a feeding cylinder 9 is fixedly connected to the bottom of the support platform 2 and to one end near the welding channel. A V-shaped block 10 for feeding is fixedly connected to the output end of the feeding cylinder 9. The V-shaped block 10 is slidably connected to the support platform 2.

[0033] It should be noted that, in this embodiment, after welding is completed, the dual-axis cylinder 19 drives the pressure plate 12 to reset upwards, the dual-axis cylinder 14 pushes the welded workpiece to the top of the limit rod 15, and the unloading cylinder 9 drives the V-block 10 to move along the welding channel, thereby pushing the welded V-frame down along the welding channel through the V-block 10.

[0034] In one embodiment, a linear module 4 is fixedly connected to both the top and bottom of the equipment base 1. A laser welding head 5 is vertically slidably connected to the moving slide of the linear module 4. A dual-axis cylinder 3 is fixedly connected to the end of the laser welding head 5. The output end of the dual-axis cylinder 3 is fixedly connected to the moving slide of the linear module 4.

[0035] It should be noted that in this embodiment, the linear module 4 moves the laser welding head 5 to a preset position, and the dual-axis cylinder 3 extends, thereby driving the laser welding head 5 to move towards the workpiece. When the dual-axis cylinder 3 reaches the limit position, the linear module 4 drives the laser welding head 5 to move along the welding channel, so that the laser welding head 5 performs welding along the joint of the workpiece.
