[0003] At present, the tip of the electrode of the spot welding machine will be deformed or the diameter will increase due to high temperature corrosion, oxidation or friction after long-term use, and this change will cause the current density to decrease during welding, and local heating to be uneven, in order to maintain the welding strength, the equipment will automatically increase the current, and then cause the metal to overheat and splash, resulting in an increase in splashes during the welding process, and too many splashes will adhere to the surface of the electrode to form foreign matter, so that the electrode needs to be polished and cleaned frequently, which not only accelerates the consumption of the electrode, but also increases the replacement frequency of the electrode, in addition, the splashes may also enter the internal part of the equipment, causing short circuit or poor contact of the electronic components, and seriously affecting the service life of the electronic components.

[0036] The sensing component 26 includes a sensing cylinder 261 that communicates with the cone 22. A piston plate 262 is fixedly connected to the inner wall of the sensing cylinder 261 by a spring. An air vent 43 is provided on the side wall of the sensing cylinder 261. An elastic pressure rod 27 is fixedly connected to the side wall of the piston plate 262 near the spring. A pressure sensor 28 is fixedly connected to the inner wall of the sensing cylinder 261. The end of the elastic pressure rod 27 away from the piston plate 262 contacts the pressure sensor 28, which can detect whether the welding electrode 14 is worn.

[0037] A small electric push rod 29 is fixedly connected to the upper side wall of the detection cylinder 161. The moving end of the small electric push rod 29 is fixedly connected to the top plate 30, which can keep the insertion cylinder 21 and the detection cylinder 161 relatively fixed.

[0038] The inner wall of the mounting cover 131 is fixedly connected to two placement frames 37. The inner wall of the left placement frame 37 is fixedly connected to multiple longitudinally distributed laser generators 38, and the inner wall of the right placement frame 37 is fixedly connected to multiple longitudinally distributed laser receivers 39, which can detect the amount of splashes.

[0039] The upper sidewall of the hollow plate 12 is rotatably connected to a rotating tube 40, and the upper end of the rotating tube 40 is fixedly connected to a grinding tube 41. The grinding tube 41 is inclined and the tube wall of the grinding tube 41 is fixedly connected to a grinding layer. The tube wall of the grinding tube 41 has multiple suction ports. The upper sidewall of the hollow plate 12 is fixedly connected to a drive motor 42. The output end of the drive motor 42 is connected to the rotating tube 40 through a gear transmission assembly, which can clean foreign objects on the surface of the welding electrode 14.

[0040] The operating principle of this invention is explained as follows: The clamp is fitted onto the outside of the limiting seat 5, so that the lower sidewall of the clamp contacts the electrode plate 6 on the surface of the limiting seat 5. Then, an electrical signal is sent to the controller 2 through an external switch. After receiving the electrical signal, the controller 2 controls the blocking motor 8 to work. The blocking motor 8 drives the baffle 9 to rotate, so that the baffle 9 rotates to the right side of the clamp. Then, the controller 2 controls the first lead screw drive module 7 to work (the lead screw drive module consists of a drive box, a motor, a threaded rod, and a threaded cylinder. The motor controls the rotation of the threaded rod, and the threaded rod drives the threaded cylinder to move through the threaded engagement, and the threaded cylinder drives the required components to move). The lead screw drive module 7 will drive the blocking motor 8 and the baffle 9 to move to the set position. The baffle 9 will fix the clamp. Then the controller 2 will control the two first electric push rods 3 to work. The two first electric push rods 3 will drive the lifting plate 4 to move downward. The lifting plate 4 will drive the mounting cover 131 to move downward together. The mounting cover 131 will drive the connecting seat 132 and the two welding electrodes 14 on the lower side of the connecting seat 132 to move downward together through the elastic rod. The welding electrodes 14 will first contact the bracket on the surface of the clamp. The mounting cover 131 will contact the surface of the clamp under the drive of the lifting plate 4. At this time, the bracket and the welding electrodes 14 will be located inside the mounting cover 131.

[0041] Next, controller 2 energizes the two welding electrodes 14 to weld the clamp and bracket. During welding, spatter generated by the clamp and bracket will scatter in all directions, falling into the storage frame 15 inside the mounting cover 131 or adhering to the inner wall of the mounting cover 131. Some spatter will pass through the two placement frames 37 during the scattering process. The laser signal emitted by the laser generator 38 in the left placement frame 37 will be blocked by the spatter. Controller 2 detects the amount of spatter through the laser receiver 39. When controller 2 detects a large amount of spatter through the laser receiver 39, controller 2 will control the first electric push rod 3 to move the lifting plate 4 and welding head assembly 13 upwards to the initial position after the clamp welding is completed. Next, the second electric push rod 10 is controlled to operate. The second electric push rod 10 drives the hollow plate 12 upwards to a set position via the second lead screw drive module 11. Then, the controller 2 controls the second lead screw drive module 11 to operate, which drives the detection component 16 to move directly below the left welding electrode 14. Next, the controller 2 controls the second electric push rod 10 to continue operating, driving the detection component 16 upwards to a set position, so that the lower end of the welding electrode 14 is inserted into the cone 22. The cone 22 and the lower end of the welding electrode 14 are in close contact. When there are no foreign objects attached to the surface of the welding electrode 14, after the second electric push rod 10 stops operating, the controller 2 controls the small electric push rod 29 to operate, causing the small... The electric push rod 29 pushes the lower wall of the insert 21 using the top plate 30. Then, the controller 2 controls the air pump 24 to work, which extracts the gas inside the collection box 23, and the gas inside the hollow plate 12 is also extracted. The detection cylinder 161 is fixedly connected to the hollow plate 12 through the short pipe 162, and the detection cylinder 161 is connected to the insert 21 through the riser pipe 20. The gas inside the insert 21 is discharged to the outside by the air pump 24. When the lower end of the welding electrode 14 is not worn, the lower end of the welding electrode 14 will fit tightly against the inner wall of the cone 22 and block all the sensing cylinders 261. When the lower end of the welding electrode 14 is worn, the lower end of the welding electrode 14 will become shorter, and the lower end of the welding electrode 14 will be located at several sensing cylinders. Above cylinder 261, the seal on induction cylinder 261 is released, allowing it to connect with the outside. Since the piston plate 262 inside induction cylinder 261 is under negative pressure near the spring (gas is extracted from the side of piston plate 262 near the spring through vent 43, creating a negative pressure on that side), once connected, the piston plate 262 moves towards the vent 43. After passing the vent 43, it directly connects to the outside, stopping the piston plate 262's movement. During this movement, the piston plate 262 is pressed against the pressure sensor 28 by the elastic rod 27, causing the pressure sensor 28 to send an electrical signal to the controller 2.Upon receiving this electrical signal, controller 2 indicates that the welding electrode 14 is worn and needs to be replaced promptly.

[0042] When foreign matter adheres to the surface of the welding electrode 14, as the detection component 16 moves the cone 22 upward to the set position, the cone 22, under the action of the foreign matter, will move the lifting tube 20, the detection plate 17, and the conductive frame 18 downward together through the insertion tube 21, causing the conductive frame 18 to contact the conductive plate 19. The conductive frame 18 is electrically connected to the external power supply, and the conductive plate 19 is electrically connected to the controller 2. When the two contact, an electrical signal is sent to the controller 2, indicating that foreign matter is adhered to the surface of the welding electrode 14. The controller 2 will then control the second electric push rod 10 to move the hollow plate 12 and other components downward to the set position, and control the second lead screw drive module. In step 11, the second lead screw drive module 11 drives the grinding tube 41 to move directly below the welding electrode 14. Then, the controller 2 controls the drive motor 42 to work. The drive motor 42 drives the rotating tube 40 and the grinding tube 41 to rotate together through the gear transmission assembly, so that the grinding tube 41 rotates along the periphery of the welding electrode 14. The grinding layer on the surface of the grinding tube 41 is used to grind the foreign matter attached to the surface of the welding electrode 14. During the grinding process, the controller 2 also controls the air pump 24 to work at the same time. According to the above principle, the foreign matter ground off the welding electrode 14 will be sucked in through the surface of the grinding tube 41 and transported to the collection box 23 for storage.

[0043] Once the welding electrode 14 is functioning normally, the problem might be increased spatter due to oil contamination on the clamp surface. Before welding the next clamp, the controller 2 will operate the second electric push rod 10, which will drive the second lead screw drive module 11, the hollow plate 12, and the grinding assembly 31 upwards to a set position. Then, the controller 2 will operate the second lead screw drive module 11, which will drive the grinding assembly 31 to move above the clamp. During the operation of the second lead screw drive module 11, the controller 2 will also operate the grinding electric push rod 36, which will drive the grinding roller 31. 2. The surface of the clamp is in contact with the clamp. At the same time, the controller 2 will also control the grinding motor 32 to work. The grinding motor 32 drives the grinding roller 312 to grind the oil stains on the surface of the clamp. At the same time, the controller 2 will also control the air pump 24 to work. According to the above principle, the impurities ground off will be transported to the collection box 23 through the dust suction hole on the surface of the grinding roller 312. The air pump 24 has a large power. During the process of detecting the wear degree of the welding electrode 14, even if the external gas enters the collection box 23 through the dust suction hole on the surface of the grinding roller 312 and the suction port on the surface of the grinding tube 41, the side of the piston plate 262 near the spring will maintain a negative pressure state.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
