Description

Technical Field

[0001] This utility model relates to the field of automotive plastic parts technology, specifically to a laser welding machine for automotive plastic parts. Background Technology

[0002] With the rapid development of the automotive industry, lightweighting has become an important trend in automotive design. Plastic parts used in automobile manufacturing are widely used due to their advantages such as light weight, corrosion resistance, and ease of processing and molding. They can not only effectively reduce the curb weight of automobiles and improve fuel efficiency, but also reduce environmental pollution to a certain extent. Common plastic parts for automobiles include, but are not limited to, bumpers, interior parts, and body panels. These plastic parts play an important role in the safety, comfort, and aesthetics of automobiles.

[0003] According to patent document CN210190643U, a laser welding machine with strong light protection for plastic parts production is disclosed. The machine includes a laser welding machine body, a support arm fixedly mounted at the top of the machine body, a welding head fixedly mounted at one end of the support arm, a worktable fixedly connected to one side of the machine body, a protective frame fixedly connected to the top of the worktable, a sliding frame slidably connected to the front end of the protective frame, a fixed plate fixedly connected to the lower side of the front end of the sliding frame, a hydraulic cylinder fixedly mounted between the top of the fixed plate and the bottom of the worktable, a flat lens mounted at the front end of the sliding frame, and a mounting groove formed on one side of the sliding frame. This invention improves the performance of the laser welding machine with strong light protection for plastic parts production, effectively blocking the strong light generated by the laser welding machine, preventing harm to workers, and also preventing harmful gases from damaging their health.

[0004] When laser welding automotive plastic parts, the plastic parts are usually placed on a mold, and then the welding head on the laser welding machine body descends to cover the top of the mold to perform the welding operation. However, because there are limiting structures around the mold, the plastic parts may shift due to improper placement during the welding operation, thus affecting the welding quality. In addition, when placing the plastic parts, since the laser welding head is usually facing the top of the mold, if the operator's hand accidentally enters the irradiation range of the laser welding head, it can easily cause hand injury, posing a certain safety hazard.

[0023] Please see Figure 3-4 The base 1 includes two support plates 11, with a top plate 12 fixedly connected to the top of the two support plates 11. Side connecting rods 13 are fixedly connected to the front and rear sides of the left and right sides of the top plate 12. Two bidirectional screw connecting blocks 15 are fixedly connected to the rear sides of the two rear side connecting rods 13 on one side of the top of the top plate 12.

The outer walls of the double-acting screw 115 are rotatably connected to the inner walls of two double-acting screw connecting blocks 15 on both sides. The outer walls of the double-acting screw 115 are threaded to the rear side of two inverted L-shaped expansion plates 17 on both sides of the inner side of the two double-acting screw connecting blocks 15.

[0024] When welding automotive plastic parts is required, the parts to be welded are first placed on the mold plate 110. Then, the motor 111 is started. The output of the motor 111 drives the turntable 112 to rotate. The outer wall of the turntable 112 drives the track 113 to rotate. The inner wall of the track 113 away from the turntable 112 drives the second turntable 114 to rotate. The right side of the second turntable 114 drives the double-acting screw 115 to rotate on the inner wall of the two double-acting screw connecting blocks 15. The outer wall of the double-acting screw 115 rotates on the inner wall of the two double-acting screw connecting blocks 15.

The bottom inner side of each of the two sets of V-shaped rotating rods 26 is rotatably connected to the inner wall of the two sets of hinge blocks 19.

[0026] When the two inverted L-shaped expansion plates 17 slide towards each other on both sides of the inner walls of the two guide grooves 16, the inner sides of the two inverted L-shaped expansion plates 17 drive the two clamping plates 18 to clamp and fix the automotive plastic parts on the mold plate 110. At the same time, the inner walls of the two hinge blocks 19 drive the two sets of V-shaped rotating rods 26 to rotate towards each other. The inner tops of the two sets of V-shaped rotating rods 26 drive the two welding head partition control plates 24 to slide away from each other on the outer walls of the two sets of columnar crossbars 23. The inner bottoms of the two welding head partition control plates 24 drive the two partitions 27 to move away from each other, so that the two clamping grooves 28 can release the limit on the bottom of the welding head 210 and the welding head 210 is no longer separated from the bottom mold plate 110. At this time, the welding head 210 can freely perform laser welding operations on the automotive plastic parts on the mold plate 110 under the control of the welding machine control plate 29.

[0027] Working principle: When welding automotive plastic parts is required, the automotive plastic parts to be welded are first placed on the mold plate 110. Then, the motor 111 is started.

The inner wall of the track 113 away from the turntable 112 drives the second turntable 114 to rotate. The right side of the second turntable 114 drives the double-acting screw 115 to rotate on the inner wall of the two double-acting screw connecting blocks 15. The outer wall of the double-acting screw 115 drives the two inverted L-shaped expansion plates 17 to slide towards each other on both sides of the inner wall of the two guide grooves 16 on both sides of the inner side of the two double-acting screw connecting blocks 15. The inner side of the two inverted L-shaped expansion plates 17 drives the two clamping plates 18 to clamp and fix the automotive plastic parts on the mold plate 110.

[0028] When the two inverted L-shaped expansion plates 17 slide towards each other on both sides of the inner walls of the two guide grooves 16, the inner sides of the two inverted L-shaped expansion plates 17 drive the two clamping plates 18 to clamp and fix the automotive plastic parts on the mold plate 110. At the same time, the inner walls of the two hinge blocks 19 drive the two sets of V-shaped rotating rods 26 to rotate towards each other. The inner tops of the two sets of V-shaped rotating rods 26 drive the two welding head partition control plates 24 to slide away from each other on the outer walls of the two sets of columnar crossbars 23. The inner bottoms of the two welding head partition control plates 24 drive the two partitions 27 to move away from each other, so that the two clamping grooves 28 can release the limit on the bottom of the welding head 210 and the welding head 210 is no longer separated from the bottom mold plate 110. At this time, the welding head 210 can freely perform laser welding operations on the automotive plastic parts on the mold plate 110 under the control of the welding machine control plate 29.
