Description

Technical Field

[0001] This utility model relates to the technical field of anti-scratch equipment for laser splicing surfaces, and in particular to an anti-scratch device for the surface of materials used in the production of laser-welded plates. Background Technology

[0002] The surface scratch protection device for laser-welded plates is a specialized piece of equipment used to protect the surface of metal sheets from mechanical damage during the laser welding process. In the automotive and aerospace industries, laser welding technology is used to connect metal sheets of different materials and thicknesses. Scratches on the surface of the sheet directly affect the welding quality, structural strength, and product aesthetics. This device avoids surface damage caused by traditional mechanical contact through low-contact transmission and positioning. Combined with cleaning and protection technologies, it ensures that the sheet maintains high surface integrity throughout the entire processing.

[0003] Early anti-scratch devices mainly used a structure of mechanical roller conveying combined with rigid clamp positioning. This contact design inevitably caused indentations and scratches on the surface of the sheet material, and the positioning accuracy was severely affected by mechanical wear. Existing technology uses a combination of air flotation platform and vision positioning system to avoid mechanical damage by adopting a bottom contact conveying method. However, existing devices still have significant shortcomings: in terms of pretreatment, the cleaning unit uses a single ion air dust removal, which cannot effectively remove the microscopic oil film and oxide layer on the surface of the sheet material, resulting in poor adhesion of the subsequent protective film. These insufficient pretreatments cause pores in laser splicing, which seriously restricts the application effect of the device in the field of high-end manufacturing. Utility Model Content

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0034] Reference Figure 1 , Figure 6 and Figure 7The present invention provides an embodiment of a surface anti-scratch device for laser welding plate production, comprising a workbench 1, which is an important platform for laser welding. Multiple pressure-reducing blocks 4 are fixedly connected to the outer side of the workbench 1, serving as modules for buffering pressure. Welding mechanisms 3 are provided at the top of the multiple pressure-reducing blocks 4, which are important mechanisms for achieving the welding target. A protective mechanism 2 is provided at the bottom of the inner wall of the workbench 1 to reduce the problem of cracks in welding. Rear side plates 9 are fixedly connected to the right side of the two pressure-reducing blocks 4 on the right side, which are important modules for fixing the rear structure.

[0035] The protective mechanism 2 includes two rotating shafts 201, which are important columns for achieving rotation. The front and rear ends of the two rotating shafts 201 are rotatably connected to the left and right sides of the bottom inner wall of the workbench 1, respectively. The outer walls of the rotating shafts 201 are equipped with conveyor belts 202, which are important hubs for welding conveying. The inner walls of the conveyor belts 202 are equipped with heating belts 203, which are important circulation belts for achieving continuous heating. Multiple heating rods 204 are fixedly connected to the inner walls of the heating belts 203, which are important sources of heat energy for heating. The front and rear ends of the multiple heating rods 204 are fixedly connected with heat-conducting rings 205, which can transfer heat energy. Dust covers 206 are fixedly connected to the opposite sides of the two heat-conducting rings 205 to prevent dust from entering the equipment. A constant temperature component 207 is provided on the right side of the heat-conducting rings 205, which can realize the recovery and storage of heat energy.

[0036] Specifically, the workbench 1 serves as a crucial platform for the entire equipment. Multiple pressure-reducing blocks 4 significantly reduce the impact force generated during welding. The welding mechanism 3 is a vital component for achieving the target welding. This mechanism can perform high-precision welding tasks on the target through flexible direction changes. To prevent welding cracks, the protective mechanism 2 can preheat the target before welding to induce cracks. Before the welding task begins, the heating rollers 204 can be activated. Multiple heating rollers 204 can rapidly generate heat energy, which will act on the heating band 203 through the outer wall, allowing the heating band 203 to achieve a continuous heating effect. The heating belt 203 rotates synchronously with the rotating shaft 201, achieving uniform heating. The welding target is conveyed to the surface of the conveyor belt 202. When excessive heat occurs, the heat-conducting ring 205 transfers the excess heat to the constant temperature component 207, allowing for further preheating and reducing or avoiding welding cracks. The welding target receives continuous preheating under the action of the heated conveyor belt 202, thus preventing porosity in the welding process.

[0037] Reference Figure 6 , Figure 8The constant temperature component 207 includes a heat rod 2071, which can store excess heat energy in the device. The outer wall of the heat rod 2071 is rotatably connected to the right side of the inner wall of the heat conducting ring 205. The front and rear ends of the outer wall of the heat rod 2071 are rotatably connected to heat absorption rings 2072, which are important modules for absorbing excess heat energy. The front end of the heat rod 2071 is rotatably connected to a heat insulation cover 2073. In order to achieve the function of protecting and storing heat energy, the outer wall of the heat insulation cover 2073 is fixedly connected to a heat transfer device 2074. In order to achieve further heat energy transfer, the outer wall of the heat transfer device 2074 is slidably connected to a bracket 2075, which can realize vertical movement of the frame. The bottom of the bracket 2075 is fixedly connected to multiple heat spray nozzles 2076, which can achieve a stable balance of the target after welding and prevent the occurrence of cracks due to temperature difference.

[0038] Specifically, excess heat is stored in the heat-conducting ring 205. The heat-absorbing ring 2072 rotates and absorbs heat on the inner wall of the heat-conducting ring 205, storing the heat inside itself and then transporting and storing the heat in the heat rod 2071. The heat insulation cover 2073 further stores and insulates the stored heat. After the target welding is completed, the heat in the heat rod 2071 is transported to the support 2075 through the heat transfer device 2074. When it is necessary to set the height temperature balance, the support 2075 can be moved vertically on the outer wall of the support 2075, which can improve the flexibility of the equipment. When the specified height is reached, the heat in the support 2075 will be used to balance the temperature of the welding target below through multiple heat spray nozzles 2076 to avoid cracking caused by temperature difference after welding.

[0039] Reference Figure 3 , Figure 4 and Figure 5The welding mechanism 3 includes two hollow blocks 301, which are important frame platforms of the welding mechanism 3. The adjacent sides of the two hollow blocks 301 are fixedly connected to the front and rear ends of the pressure reducing blocks 4, respectively. The top of the hollow blocks 301 is slidably connected to a welding base 302, which is an important base for realizing welding displacement. The adjacent side of the welding base 302 is slidably connected to a welding frame 303, which is a device for realizing vertical welding displacement. The front and rear sides of the welding frame 303 are slidably connected to welding arms 304, which are important welding facilities. The bottom of the welding arm 304 is threadedly connected to a fixing ring 305, which can be used to fix the welding laser head. The adjacent sides of the two pressure reducing blocks 4 on the left and right sides are equipped with A clamping assembly 306 is provided to fix the welding target. A cleaning assembly 307 is provided on the bottom right side of the welding chassis 302 to clean up residue after welding. The cleaning assembly 307 includes a rear block 3071, the left side of which is fixedly connected to the bottom right side of the pressure reducing block 4. A protective cover 3073 is fixedly connected to the right side of the rear block 3071 to prevent residue from splashing out. Multiple magnets 3072 are fixedly connected to the bottom of the rear block 3071 to attract metal residue. Motors 3075 are fixedly connected to the front and rear ends of the bottom of the protective cover 3073. The power source includes a rotating block 3074 rotatably connected to the output end of the front motor 3075. A brush shaft 3076 is rotatably connected to the adjacent side of the rotating block 3074 for scraping surfaces. A limit ring 3077 is rotatably connected to the front end of the brush shaft 3076 for fixing it. Two clamping components 306 include scale bars 3061, enabling high-precision positioning. The left and right sides of the two scale bars 3061 are fixed to adjacent sides of two pressure-reducing blocks 4. Multiple locking blocks 3062 are fixedly connected to the top of each scale bar 3061, forming an important module for horizontal movement. Stabilizing blocks 3063 are slidably connected to the front and rear sides of the measuring bar 3061. Stabilizing blocks 3064 are slidably connected to the top of the two stabilizing blocks 3063. Telescopic columns 3065 are fixedly connected to the inner walls of the two stabilizing blocks 3064, which can achieve compression clamping of the welding target. Protective sleeves 3066 are rotatably connected to the opposite sides of the two telescopic columns 3065 to prevent excessive compression from causing rebound force. Force-applying blocks 3067 are fixedly connected to the adjacent sides of the two telescopic columns 3065. Fixing plates 3068 are fixedly connected to the adjacent sides of the two force-applying blocks 3067, which are important metal plates for achieving compression welding target.

[0040] Specifically, when the welding target reaches above conveyor belt 202, it can be adjusted to a suitable size by moving stabilizing block 3063 and stabilizing block 3064. The bottom of stabilizing block 3063 can be clipped onto the top of stabilizing block 3062 to achieve a fixing effect. Then, the bottom of stabilizing block 3064 can be clipped onto the top of stabilizing block 3063. The protective sleeve 3066 can be used to activate the telescopic column 3065 on the inner wall of stabilizing block 3064. The telescopic column 3065 will push the force-applying block 3067. The force-applying block 3067 will act on the fixing plate 3068, and the two fixing plates 3068 will move synchronously towards the center. Interval compression can be used to clamp the welding target. The welding base 302 can move horizontally on the top of the hollow block 301. The welding frame 303 can move vertically on the welding base 302. The welding arm 304 can also move horizontally on the welding frame 303. The fixing ring 305 is an important fixing device for fixing the welding laser head. When the welding work is completed, slag will inevitably be generated. The generated slag will be conveyed to the bottom of the rear block 3071. Multiple magnets 3072 will attract the metal slag. The slag that cannot be attracted will be cleaned out by the rotation of the brush shaft 3076.

[0041] Reference Figure 1 , Figure 4 The two front side plates 5 are fixedly connected to the adjacent side of the rotating shaft 2 7, which is an important device for inputting and conveying the welding target. The outer wall of the rotating shaft 2 7 is provided with a conveyor belt 2 6, which is an important channel for bringing the welding target into the welding area. The top of the two rear side plates 9 is fixedly connected to the bottom of the rotating block 3074 respectively. The bottom front and rear ends of the two front side plates 5 and the rear side plates 9 are fixedly connected to suction cups 8, which are important support legs for stabilizing the equipment. The top of the front side plates 5 is fixedly connected to the baffle plate 10, which is an important fixed support for fixing the blower 11. The two baffle plates 10 are fixedly connected to the adjacent side of the blower 11, which can blow away the surface before welding.

[0042] Specifically, the target to be welded is conveyed to the surface of the conveyor belt 6 on the outer wall of the rotating shaft 2 7, and the target to be welded can be conveyed to the welding point. Multiple suction cups 8 can absorb and relieve the pressure generated during the welding operation. In order to further avoid and reduce the weld cracks, the target to be welded can be cleaned of surface impurities under the strong blowing force of the blower 11.

[0043] Working principle: Before welding, the heating rollers 204 can be activated. Multiple heating rollers 204 can quickly generate heat energy, which will act on the heating belt 203 through the outer wall, so that the heating belt 203 can achieve a continuous heating effect. The heating belt 203 will rotate synchronously under the action of the rotating shaft 201, so that the heating belt 203 can achieve a uniform heating effect. The welding target is conveyed to the surface of the conveyor belt 202. When there is excessive heat energy, the excess heat energy can be transferred to the constant heat energy under the action of the heat conduction ring 205. Within the heat-generating component 207, excess heat energy can be used for other preheating effects, further reducing and avoiding welding cracks. The welding target can receive continuous preheating under the action of the heated conveyor belt 202, thus preventing porosity in the weld. Excess heat energy is stored in the heat-conducting ring 205. The heat-absorbing ring 2072 rotates and absorbs heat on the inner wall of the heat-conducting ring 205, storing the heat energy within itself, and then transporting and storing the heat energy in the heat rod 2071. The heat-insulating cover 2073 further stores and preserves the stored heat energy. The heating element works as follows: after the target welding is completed, the heat energy in the heat rod 2071 is transported to the support 2075 through the heat transfer device 2074. When a height temperature balance needs to be set, the support 2075 can be vertically moved on its outer wall, improving the flexibility of the equipment. When the designated height is reached, the heat energy in the support 2075 is used to balance the temperature of the welding target below through multiple heat nozzles 2076 to avoid cracking caused by temperature differences after welding. When the welding target reaches above the conveyor belt 202, it can be stabilized by moving the stabilizing block 306. 3. Adjust the stabilizer block 3064 to the appropriate size. The bottom of the stabilizer block 3063 can be snapped onto the top of the locking block 3062 to achieve a fixing effect. Then, snap the bottom of the stabilizer block 3064 onto the top of the stabilizer block 3063. The protective sleeve 3066 can be used to activate the telescopic column 3065 on the inner wall of the stabilizer block 3064. The telescopic column 3065 will push the force application block 3067. The force application block 3067 will act on the fixing plate 3068. The two fixing plates 3068 will compress towards the middle at the same time, which can act as a clamping effect on the welding target.

[0044] Furthermore, the welding base 302 can move horizontally on the top of the hollow block 301, the welding frame 303 can move vertically on the welding base 302, and the welding arm 304 can move horizontally on the welding frame 303. The fixing ring 305 is an important fixing device for fixing the welding laser head. When the welding work is completed, slag will inevitably be generated. The generated slag will be conveyed to the bottom of the rear block 3071. Multiple magnets 3072 will attract the metal slag. The slag that cannot be attracted will be cleaned out by the rotation of the brush shaft 3076. The target to be welded is conveyed to the surface of the conveyor belt 6 on the outer wall of the rotating shaft 7. The target to be welded can be conveyed to the welding point. Multiple suction cups 8 can withstand and relieve the pressure generated during the welding operation. In order to further avoid and reduce the weld cracks, the target to be welded can be cleaned of surface impurities by the strong blowing force of the blower 11.
