Description

Technical Field

[0001] This utility model belongs to the field of laser processing technology, specifically an automatic feeding laser welding device. Background Technology

[0002] Laser welding is a precision welding technology that uses a high-energy-density laser beam as a heat source to locally melt and join materials. It generates laser light through a laser, which is focused by an optical system to form a spot with a diameter of micrometers to millimeters. The energy is concentrated at the joint of the workpiece, causing the material to melt rapidly and then cool and solidify, thereby achieving welding.

[0003] Currently, laser welding equipment is an industrial device that uses the high energy density of a laser beam to join materials. Its core principle is to use the high temperature generated by focusing the laser beam to locally melt or vaporize the workpiece, and then form a strong welded joint after cooling.

[0004] Currently, after long-term observation, it has been found that existing laser welding devices can only weld certain areas of the workpiece because the fixed position of the workpiece cannot be changed. When welding other parts of the workpiece is required, the workpiece needs to be re-fixed, which consumes a lot of time and increases the welding time of each workpiece, thus affecting welding efficiency. Therefore, an automatic feeding laser welding device is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5This utility model provides an automatic feeding laser welding device, including a laser generator cabinet 1; characterized in that: a laser transmission optical path 11 is fixedly connected to the side wall of the laser generator cabinet 1; a laser welding head assembly 12 is fixedly connected to the side wall of the laser transmission optical path 11; two sets of legs 13 are provided at the front end of the laser generator cabinet 1; a transmission frame 14 is fixedly connected to the end of the legs 13; a first motor 15 is symmetrically fixedly connected to the inner side wall of the transmission frame 14; a double-headed gear rod 16 is provided at the output end of the first motor 15; a track shell 17 is fixedly connected to the side wall of the transmission frame 14; the double-headed gear rod 16 is rotatably connected to the inner side wall of the track shell 17; a toothed conveyor belt 18 is slidably connected to the side wall of the track shell 17; the toothed conveyor belt 18 and the double-headed gear rod 16 are meshed; a rotating roller 1 is fixedly connected to the side wall of the track shell 17. 9; A toothed conveyor belt 18 is rotatably connected to the side wall of the rotating roller 19; a connecting conveyor belt 101 is fixedly connected to the outer side wall of the toothed conveyor belt 18; a fixing block 102 is fixedly connected to the inner side wall of the connecting conveyor belt 101; a rotating disk 103 is rotatably connected to the inner side wall of the fixing block 102; a placement disk 104 is fixedly connected to the end of the rotating disk 103; multiple sets of fixing plates 105 are fixedly connected to the end of the placement disk 104; the fixing plates 105 are arranged in a circumferential array; a cylinder 106 is fixedly connected to the side wall of the fixing plate 105; a clamping plate 107 is fixedly connected to the output end of the cylinder 106; multiple sets of first springs 108 are fixedly connected to the side wall of the clamping plate 107; a hard rubber sheet 109 is fixedly connected to the end of the first spring 108; multiple sets of handle brackets 110 are fixedly connected to the side wall of the placement disk 104; the handle brackets 110 are arranged in a circumferential array.During operation, the weldment is first placed on the placement tray 104. Then, the cylinder 106 is activated to drive the clamping plate 107 to slide inward until the hard rubber sheet 109 contacts the weldment and clamps it. At this time, the first spring 108 is compressed under pressure. When the clamping is fixed, the first spring 108 generates a reaction force on the hard rubber sheet 109, which applies additional compressive force to the weldment, improving the clamping effect. Subsequently, the control system starts the first motor 15 to drive the double-headed gear rod 16 to rotate. The rotation of the double-headed gear rods 16 on both sides drives the toothed conveyor belt 18 to move. At the same time, the meshing connection between the double-headed gear rods 16 and the toothed conveyor belt 18 improves the stability of the conveyor belt. Then, the connecting conveyor belt 101 drives the clamping mechanism and the weldment. The workpiece is conveyed to the welding area, where it is welded using the laser welding head assembly 12. During welding, the control system issues commands to adjust the position of the workpiece, and the manual operation of the handle 110 can drive the rotating disk 103 to rotate. This allows different parts of the workpiece to be positioned below the laser welding head assembly 12, enabling the laser welding head assembly 12 to weld different areas of the workpiece. This design uses a conveyor belt to automatically feed the workpiece to the welding area. Simultaneously, a clamping mechanism securely holds the workpiece, and by rotating the clamping structure and adjusting the position of the clamping mechanism and the workpiece using the conveyor belt, different positions of the workpiece can be positioned directly below the welding area, thus enabling welding operations at different locations and improving welding efficiency.

[0028] Furthermore, such as Figure 5 As shown, the clamping plate 107 has multiple sets of buffer grooves 2 symmetrically opened on its side wall; a second spring 21 is fixedly connected to the side wall of the buffer groove 2; a splicing plate 22 is fixedly connected to the end of the second spring 21; a ball head 23 is symmetrically fixed to the side wall of the splicing plate 22; a soft rubber sheet 24 is rotatably connected to the side wall of the ball head 23; during operation, when the clamping plate 107 clamps the weldment, the soft rubber sheets 24 on both sides also clamp the weldment through the rebound force generated by the second spring 21. At the same time, due to the setting of the ball head 23 and the softness of the soft rubber sheet 24, the soft rubber sheet 24 can be angularly offset, and the upper and lower ends can be twisted and fitted to different degrees according to the shape of the weldment, so as to achieve a tight fit effect according to the different shapes and sizes of the weldment, thereby increasing the fitting area of ​​the weldment. This design, through the setting of the adaptive tight-fitting clamping mechanism, can increase the fitting area when clamping the weldment, thereby enhancing the working area of ​​the clamping force, and thus increasing the clamping force on the weldment and improving the clamping stability of the weldment.

[0029] Furthermore, such as Figure 6As shown, an exhaust device 3 is fixedly connected to the side wall of the transmission frame 14; multiple sets of vent pipes 31 are arranged on the side wall of the exhaust device 3; the vent pipes 31 are arranged in a circumferential array; a venting balloon 32 is provided at the output end of the vent pipe 31; a jet nozzle 33 is rotatably connected to the side wall of the venting balloon 32; during operation, when the conveyor transports the welded parts, the exhaust device 3 is activated to generate gas, which is transported through the vent pipes 31 and then through the venting balloon 32 to the jet nozzle 33, where the gas is ejected. At the same time, the jet nozzle 33 is rotated to adjust its spray angle so that it is directed towards the center area of ​​the conveyor belt, thereby achieving jet treatment of the welded parts. Jet treatment can reduce dust on the welded parts. This design, through the jet device, can remove dust from the welded parts, reducing the amount of dust remaining on the welded parts, thereby reducing the situation of insufficient or uneven laser energy distribution in the welding area when laser welding the welded parts, and improving the welding quality.

[0030] Furthermore, such as Figure 6 As shown, a fitting frame 4 is fitted to the side wall of the vent pipe 31; a positioning bracket 41 is fixedly connected to the side wall of the exhaust device 3; the fitting frame 4 and the positioning bracket 41 are fixedly connected; during operation, the fitting frame 4 and the positioning bracket 41 provide a fitting support effect for the middle part of the vent pipe 31. By fitting and supporting the vent pipe 31, the vent pipe 31 is fitted and fixed when the gas passes through it. This fitting support device can improve the stability of the jet device during operation.

[0031] Furthermore, such as Figure 2 and Figure 4 As shown, a laser sensor 5 is fixedly attached to the side wall of the laser welding head assembly 12; a height-fixing plate 51 is fixedly attached to the side wall of the fixing block 102. During operation, as the fixing block 102 moves towards the lower end of the leg frame 13, the laser sensor 5 continuously emits a signal. When the height-fixing plate 51 is directly facing the lower end of the laser sensor 5 emitting the signal, the laser sensor 5 receives the signal and the emission height decreases. At this time, it sends a signal to the control system to stop the conveyor belt. At this time, the fixing block 102 is directly below the leg frame 13, and the welded part is also at the center of the welding area. The positioning process of the welded part is completed. This design, through the laser height detection device, determines the transportation position of the welded part by detecting the change in laser height, thereby realizing the transportation positioning process of the welded part, so that the welded part reaches the welding center and improves the accuracy of the welding position.

[0032] Furthermore, such as Figure 5As shown, a third spring 6 is fixedly connected to the side wall of the fixing plate 105; the third spring 6 is fixedly connected to the clamping plate 107; during operation, the third spring 6 is initially in a compressed state. When the clamping plate 107 presses the welded part, the third spring 6 is released, generating a thrust on the clamping plate 107, thereby increasing the clamping force of the clamping plate 107 on the welded part. This design improves the clamping stability of the welded part by increasing the clamping force on the welded part.

[0033] Working principle: First, the weldment is placed on the placement tray 104. Then, the cylinder 106 is activated to drive the clamping plate 107 to slide inward until the hard rubber sheet 109 contacts the weldment and clamps it. At this time, the first spring 108 is compressed under pressure. When clamped and fixed, the first spring 108 generates a reaction force on the hard rubber sheet 109, which applies additional compressive force to the weldment, improving the clamping effect. Then, the control system starts the first motor 15 to drive the double-headed gear rod 16 to rotate. The rotation of the double-headed gear rods 16 on both sides drives the toothed conveyor belt 18 to move. At the same time, the meshing connection between the double-headed gear rods 16 and the toothed conveyor belt 18 improves the conveying speed. The stability of the belt is ensured, and then the connecting conveyor belt 101 drives the clamping mechanism and the weldment to be transported to the welding area. The welding operation is performed by the laser welding head assembly 12. During the welding process, the position of the weldment is adjusted by the control system, and the handle frame 110 can be manually operated to drive the rotating disk 103 to rotate, so that different parts of the weldment are under the laser welding head assembly 12, so that the laser welding head assembly 12 can perform welding treatment on different areas of the weldment. When the clamping plate 107 clamps the weldment, the soft rubber sheets 24 on both sides also clamp the weldment through the rebound force generated by the second spring 21. At the same time, through the setting of the ball head 23 and the softness of the soft rubber sheet 24, the soft rubber sheet 24 can be angled. The degree of offset, and the upper and lower ends can be twisted and fitted to different degrees according to the shape of the weldment, so as to achieve a tight fit effect according to the different shapes and sizes of the weldment, thereby increasing the fitting area of ​​the weldment. When the conveying device transports the weldment, the exhaust device 3 is activated to generate gas, which is transported through the vent pipe 31 and delivered to the jet head 33 through the venting balloon 32. The gas is then sprayed out through the jet head 33. At the same time, the spray angle of the jet head 33 is adjusted by rotating it so that it is aimed at the center area of ​​the conveyor belt, thereby realizing the jet treatment of the weldment. The jet treatment can reduce the dust on the weldment. The set fitting frame 4 and positioning bracket 41 provide a fitting support effect for the middle part of the vent pipe 31. The fitting support is used to fix the vent pipe 31 when the gas passes through it. As the fixing block 102 moves towards the lower end of the leg frame 13, the laser sensor 5 always sends a signal. When the height plate 51 is directly facing the lower end of the laser sensor 5, the laser sensor 5 receives the signal and the emission height decreases. At this time, it sends a signal to the control system to stop the conveyor belt. At this time, the fixing block 102 is under the leg frame 13, and the welded part is also in the center of the welding area. At this time, the positioning process of the welded part is completed. Initially, the third spring 6 is in a compressed state. When the clamping plate 107 squeezes the welded part, the third spring 6 is released and a thrust is generated on the clamping plate 107, thereby increasing the clamping force of the clamping plate 107 on the welded part.
