Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing technology, and in particular relates to a coating removal device for laser welding. Background Technology

[0002] In modern manufacturing, laser welding is widely used in fields such as automobile manufacturing, aerospace, and electronic components due to its advantages such as high welding precision, small heat-affected zone, and high welding strength. However, many workpieces to be welded are pre-coated with various functional coatings (such as anti-corrosion coatings, insulating coatings, and decorative coatings), and the presence of these coatings can have a significant negative impact on the quality of laser welding.

[0003] In existing technologies, when removing coatings from electrode plates, it is not convenient to quickly position and fix the electrode plates before removal. During the operation, the electrode plates are prone to shaking or displacement, which not only reduces the accuracy of coating removal but also affects work efficiency. Moreover, traditional positioning methods cannot ensure that the load is evenly distributed on the electrode plates, which can easily cause damage to the electrode plates due to local stress concentration. In addition, traditional positioning mechanisms are not convenient to quickly adjust to achieve compatible fixation when dealing with electrode plates of different specifications and thicknesses, requiring a lot of time and effort to adjust, which reduces the convenience and efficiency of the overall work. Utility Model Content

[0004] The purpose of this invention is to provide a coating removal device for laser welding, which solves the problem that in the prior art, when removing coatings from electrodes, it is not convenient to quickly position and fix the electrodes before removal, and the electrodes are prone to shaking or displacement during operation. This not only reduces the accuracy of coating removal, but also affects work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a coating removal device for laser welding, including a base plate and an electrode plate. The base plate is provided with a positioning mechanism and a rotating mechanism. A pulsed laser stripping machine is fixedly connected to the top of the base plate. The positioning mechanism is used for multi-station positioning of multiple electrode plates. The pulsed laser stripping machine removes the coating from the multiple electrode plates after positioning.

[0007] The positioning mechanism includes a fixed column fixedly connected to the top surface of the base plate. A support disk is rotatably connected to the outer wall of the fixed column. Several fixed bases are fixedly connected to the top of the support disk. The several fixed bases are evenly distributed in a circular row on the top of the support disk. Two sliding rods pass through the fixed bases. A connecting rod is fixedly connected between the two sliding rods. Springs are wound around the outer walls of the two sliding rods. One end of the spring is fixedly connected to the connecting rod, and the other end of the spring is fixedly connected to the fixed base. The springs are always in a compressed state.

[0008] Furthermore, a hinge block is fixedly connected to the end of each of the two slide rods away from the connecting rod, and two hinge rods are hinged to the inner wall of each of the two hinge blocks.

[0009] Furthermore, each of the four hinge rods has a clamping plate hinged to one end away from the hinge block, and four limiting plates are fixedly connected to the fixed base, with each of the four clamping plates sliding through the four limiting plates respectively.

[0010] Furthermore, the rotating mechanism includes a circular groove formed on the top of the base plate, the inner wall of which is slidably connected to the outer wall of the supporting disc.

[0011] Furthermore, a motor is fixedly connected to the top of the base plate, and a rotating rod is fixedly connected to the output end of the motor via a coupling. A gear is fixedly connected to the outer wall of the rotating rod.

[0012] Furthermore, a toothed ring is fixedly connected to the outer wall of the supporting disk, and the toothed ring meshes with a gear.

[0013] Furthermore, an electric push rod is fixedly connected to the top of the fixed column, and a push block is fixedly connected to the output end of the electric push rod.

[0014] Furthermore, a roller is rotatably connected to the bottom of the connecting rod, and the roller is located inside the push block and in contact with the inner wall of the push block.

[0015] This utility model has the following beneficial effects:

[0016] 1. By incorporating a positioning mechanism, the electrode plate is placed between four clamping plates before coating removal. A compressed spring pulls a hinge block, which in turn moves two hinge rods, bringing the upper and lower clamping plates closer together and positioning the electrode plate within the four clamping plates. This ensures the electrode plate is stably fixed during removal, preventing shaking or displacement during operation, thus improving the accuracy and efficiency of coating removal. Furthermore, the positioning mechanism is rationally designed, distributing the force evenly across the four clamping plates, avoiding localized stress concentration and damage to the electrode plate. It achieves compatible fixing of various electrode plates, and offers fast positioning and convenient operation.

[0017] 2. By incorporating a rotating mechanism, after the coating is removed from the electrode plate by the pulsed laser stripping machine, the drive motor rotates the rotating rod and gear, which in turn drives the gear ring to rotate. The gear ring drives the support disc to rotate on the inner wall of the circular groove. The circular groove provides support for the rotation of the support disc, allowing the pulsed laser stripping machine to sequentially peel the coating off the electrode plates on different fixed bases. After the roller on the fixed base rotates into the push block, the motor is turned off and the electric push rod is driven to push the roller. The roller drives the connecting rod to compress the spring, allowing the slide rod to move the hinge block. With the cooperation of the hinge rod, the upper and lower clamping plates move away from each other, allowing the electrode plate with the coating removed to be taken out. This design ensures the speed and safety of the electrode plate replacement process, significantly reduces the frequency of manual intervention and the difficulty of operation, and improves the efficiency of coating removal.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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.

[0028] Please see Figure 1-5 As shown, this utility model is a coating removal device for laser welding, including a base plate 1 and an electrode plate 4. The base plate 1 is provided with a positioning mechanism 2 and a rotating mechanism 3. A pulsed laser stripping machine 5 is fixedly connected to the top of the base plate 1. The positioning mechanism 2 is used to perform multi-station positioning of multiple electrode plates 4. The pulsed laser stripping machine 5 removes the coating from the multiple electrode plates 4 after positioning.

[0029] The positioning mechanism 2 includes a fixed column 21 fixedly connected to the top surface of the base plate 1. A support disk 22 is rotatably connected to the outer wall of the fixed column 21. Several fixed bases 23 are fixedly connected to the top of the support disk 22. The fixed bases 23 are evenly distributed in a circular arrangement on the top of the support disk 22. Two sliding rods 24 pass through the fixed bases 23. A connecting rod 25 is fixedly connected between the two sliding rods 24. Springs 26 are wound around the outer walls of both sliding rods 24. One end of the spring 26 is fixedly connected to the connecting rod 25, and the other end of the spring 26 is fixedly connected to the fixed base 23. The springs 26 are always in a compressed state. Hinged blocks 27 are fixedly connected to the ends of the four plates 24 away from the connecting rod 25. Two hinged rods 28 are hinged to the inner walls of the two hinged blocks 27. Clamping plates 29 are hinged to the ends of the four hinged rods 28 away from the hinged blocks 27. Four limiting plates 291 are fixedly connected to the fixed base 23. The four clamping plates 29 slide through the four limiting plates 291 respectively. A positioning mechanism 2 is provided to bring the clamping plates 29 on both sides closer together, positioning the electrode plate 4 inside the four clamping plates 29. This ensures that the electrode plate 4 is stably fixed during peeling, preventing shaking or displacement during operation, thereby improving the accuracy and efficiency of coating removal. Simultaneously, the positioning mechanism 2 is reasonably designed, with the force evenly distributed on the four clamping plates 29, avoiding localized stress concentration and damage to the electrode plate 4. In addition, the positioning mechanism 2 has a quick adjustment function, automatically adjusting the spacing of the clamping plates 29 according to electrode plates 4 of different specifications and thicknesses, achieving compatible fixing of various electrode plates 4.

[0030] The rotating mechanism 3 includes a circular groove 31 on the top of the base plate 1. The inner wall of the circular groove 31 is slidably connected to the outer wall of the supporting disc 22. A motor 33 is fixedly connected to the top of the base plate 1. The output end of the motor 33 is fixedly connected to a rotating rod 34 via a coupling. A gear 35 is fixedly connected to the outer wall of the rotating rod 34. A gear ring 32 is fixedly connected to the outer wall of the supporting disc 22. The gear ring 32 meshes with the gear 35. An electric push rod 36 is fixedly connected to the top of the fixed column 21. A push block 37 is fixedly connected to the output end of the electric push rod 36. A roller 38 is rotatably connected to the bottom of the connecting rod 25. The roller 38 is located inside the push block 37 and contacts the inner wall of the push block 37. By setting up the rotating mechanism 3, the replacement process of the electrode plate 4 is ensured to be rapid and safe, the frequency of manual intervention and the difficulty of operation are greatly reduced, and the efficiency of coating peeling is improved.

[0031] One specific application of this embodiment is: the pulsed laser stripping machine 5 is a device that uses pulsed laser technology to precisely strip and remove material surfaces or specific layers, and is widely used in precision manufacturing fields such as electronics, semiconductors, aerospace, and medical devices;

[0032] By setting a positioning mechanism 2, before the coating is removed from the electrode plate 4, it is placed between four clamping plates 29. The compressed spring 26 pulls the hinge block 27, and the hinge block 27 drives the two hinge rods 28 to move. This causes the clamping plates 29 on the upper and lower sides to move closer to each other, positioning the electrode plate 4 inside the four clamping plates 29. This ensures that the electrode plate 4 can be stably fixed during removal, preventing shaking or displacement during operation, thereby improving the accuracy and efficiency of coating removal. At the same time, the positioning mechanism 2 is reasonably designed, and the force is evenly distributed on the four clamping plates 29, avoiding local stress concentration and damage to the electrode plate 4, and achieving compatible fixation for various electrode plates.

[0033] With the rotating mechanism 3, after the coating is removed from the electrode plate 4 by the pulsed laser stripping machine 5, the drive motor 33 drives the rotating rod 34 and gear 35 to rotate, which in turn causes the gear 35 to drive the gear ring 32 to rotate. The gear ring 32 drives the support disc 22 to rotate on the inner wall of the circular groove 31. The circular groove 31 can provide support for the rotation of the support disc 22, so that the pulsed laser stripping machine 5 can sequentially peel off the coating from the electrode plates 4 on different fixed bases 23. After the roller 38 on the fixed base 23 rotates into the push block 37, the motor 33 is turned off and the electric push rod 36 is driven to push the roller 38. The roller 38 drives the connecting rod 25 to squeeze the spring 26, so that the slide rod 24 can drive the hinge block 27 to move. With the cooperation of the hinge rod 28, the clamps 29 on the upper and lower sides move away from each other. At this time, the electrode plate 4 after the coating is peeled off is taken out. This design ensures the speed and safety of the electrode plate 4 replacement process, greatly reduces the frequency of manual intervention and the difficulty of operation, and improves the efficiency of coating peeling.
