Description

Technical Field

[0001] This invention relates to the field of high-speed line welding, and more specifically, to a stroke-triggered welding device and method. Background Technology

[0002] Resistance welding is a welding method that uses the resistance heating effect generated by the current passing through the contact surface and adjacent areas of the workpieces to heat them to a molten or plastic state, thereby forming a metal joint.

[0003] Currently, pressure welding is commonly used in high-speed wire and terminal welding applications. Existing technology (Chinese invention patent application with publication number CN119566486A) discloses a resistance welding head and resistance welding equipment. The welding head is moved by a Scottish yoke structure for a first displacement and then by a cylinder for a second displacement, achieving dual-stroke trigger welding. Although this improves the welding accuracy and stability, the welding head needs to frequently move up and down during the welding process. The rollers in the Scottish yoke structure frequently come into frictional contact with the inner wall of the constraint groove. With the increase of usage time, the grease and dust on the outer surface of the rollers mix to form a paste. After thickening, it generates shear resistance, resulting in increased friction and a sudden increase in resistance. This can cause the rollers to jam and the welding head to intermittently stop during its lifting and lowering movements. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a solution.

[0005] To solve the above problems, the present invention adopts the following technical solution.

The device also includes a scraping assembly, which includes a scraper seat fixedly attached to one side of the base, an inclined surface at the upper end of the scraper seat, a groove on the inclined surface, a feed inlet on the inner wall of the groove, an inner cavity inside the scraper seat, a filter cartridge rotatably connected to the scraper seat and located within the inner cavity, and a discharge port inside the scraper seat that connects the inner cavity to the feed inlet.

[0007] Furthermore, the scraper seat is provided with an exhaust port that communicates with the inner cavity, and a filter screen is fixedly connected to the inner wall of the exhaust port. An air inlet connector is fixedly connected to the outer surface of one side of the seat body, and a pipe connecting the exhaust port and the air inlet connector is provided inside the seat body.

[0008] Furthermore, a cover plate is fixedly attached to one side of the mounting plate, and a through hole is opened inside the cover plate, with a plug inserted into the through hole.

[0009] Furthermore, the scraper seat is also provided with multiple oil drain grooves communicating with the inner cavity, an oil storage cavity communicating with the multiple oil drain grooves, and an oil drain port communicating with the oil storage cavity. The opening of the oil drain port is located at the lower end of the scraper seat, and a sealing plug is inserted into the opening of the oil drain port.

[0010] Furthermore, a side plate is fixedly connected to one side of the scraper seat, and a discharge port is opened inside the side plate. A synchronous wheel is rotatably connected to one side of the side plate. One side of the synchronous wheel is fixedly connected to one end of the filter cylinder, and the other end of the filter cylinder is rotatably connected to the inner wall of the inner cavity. A drive unit that drives the synchronous wheel to rotate is also connected to one side of the seat.

[0011] Furthermore, the drive unit includes a hollow column fixed to one side of the base, a rotating column with one end rotatably connected to one side of the base and the other end rotatably connected to the inner wall of the hollow column, a second synchronous pulley fixed to the outer surface of the rotating column, a first synchronous belt passing through the hollow column and connecting the first synchronous pulley to the second synchronous pulley, and a motor fixed to one side of the hollow column, with the motor's output shaft passing through the hollow column and fixed to one end of the rotating column.

[0012] Furthermore, the inner wall of the groove is provided with a movable slot, and an eccentric block is rotatably connected to the inner wall of the movable slot. A material dropping plate is rotatably connected to the inner wall of the groove via a torsion spring. A bevel gear one and a bevel gear two that are driven by the bevel gear one are rotatably connected inside the scraper seat. One side of the bevel gear one is fixedly connected to one side of the eccentric block. A pushing assembly is connected inside the seat and the scraper seat. The pushing assembly includes a synchronous wheel three and a synchronous wheel four rotatably connected inside the seat body, a synchronous belt two that connects the synchronous wheel three and the synchronous wheel four, a transmission rod rotatably connected inside the scraper seat and fixedly connected at one end to the synchronous wheel four, and the bevel gear two is fixedly connected to the other end of the transmission rod. One end of the rotating column that is rotatably connected to the seat body is fixedly connected to the synchronous wheel three.

[0013] Furthermore, two rollers are provided between the side plate and the base, and the two ends of the rollers are rotatably connected to the side plate and the base respectively. A belt is sleeved on the outside of the two rollers, and a pusher flange is fixed to the outer surface of the belt. One end of one of the rollers is fixed to a synchronous pulley six, and a synchronous pulley five is fixed to the outside of the transmission rod. The synchronous pulley five and the synchronous pulley six are connected by a synchronous belt three. The synchronous pulley six is ​​rotatably connected inside the base.

[0014] Furthermore, the welding part includes a fixing plate fixed to one side of the mounting plate, a cylinder fixed to the fixing plate, a welding head slidably connected to one side of the fixing plate and whose upper end is fixed to the telescopic end of the cylinder, and a displacement sensor fixed to the fixing plate.

[0015] A method of using a stroke-triggered welding device, comprising the following steps:

[0016] S1. The motor drives the rotating disk to rotate counterclockwise. The rotation of the rotating disk drives the base and roller to rotate. The roller rotates clockwise due to friction with the upper surface of the base. When the roller rotates, it will contact the scraper seat. The scraper seat scrapes off the material on the outer surface of the roller and the scraped material falls into the groove. The rotation of the base causes the position of the roller in the constraint groove to change, which drives the mounting plate to slide downward on one side of the bracket. When the mounting plate slides downward, it drives the welding part to move downward, so that the welding head is closer to the workpiece.

[0017] S2. The cylinder extends and lowers the welding head to weld the workpiece. After welding, the cylinder raises the welding head, and then the motor drives the rotating disk to rotate clockwise to reset. The rollers rotate clockwise due to contact and friction with the top wall of the constraint groove. The scraper continues to scrape the material on the surface of the rollers. After the rotating disk rotates clockwise to reset and the scraper resets, the material in the groove enters the feed port and is discharged from the discharge port. The material discharged from the discharge port falls into the filter cartridge.

[0018] S3. The motor drives the rotating column to rotate, which in turn drives the second synchronous pulley to rotate. The rotation of the second synchronous pulley drives the first synchronous pulley and the filter cartridge to rotate via the first synchronous belt. The rotation of the filter cartridge generates centrifugal force, which throws out the grease from the material. The grease thrown out by the filter cartridge slides off the inner wall of the cavity and flows into the oil drain groove. From the oil drain groove, it enters the oil storage chamber. By pulling out the sealing plug, the grease in the oil storage chamber can be discharged. By pulling out the plug and connecting the air inlet connector to the air pipe, gas is sprayed out from the exhaust port, blowing the impurities inside the filter cartridge out through the through hole in the cover plate.

[0019] S4. The rotation of the rotating column can also drive the rotation of the synchronous pulley three. The rotation of the synchronous pulley three drives the rotation of the synchronous pulley four and the transmission rod through the synchronous belt two. The rotation of the transmission rod drives the rotation of the synchronous pulley five. The synchronous pulley five drives the rotation of the synchronous pulley six through the synchronous belt three. The synchronous pulley six drives one of the rollers to rotate. The rotation of one of the rollers drives the other roller and the belt outside the two rollers to rotate. The material on the upper surface of the scraper seat is pushed into the groove by the pushing flange on the surface of the belt.

[0020] S5. The transmission rod can also drive the second bevel gear to rotate. The second bevel gear drives the first bevel gear and the eccentric block to rotate. When the eccentric block rotates, when the eccentric end of the eccentric block contacts the blanking plate, it can push the free end of the blanking plate upward in the groove, increasing the tilt angle of the blanking plate so that the material on the blanking plate can quickly enter the feed port.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] (1) This solution is equipped with a scraping component. When the seat rotates with the rotating disk and drives the roller to rotate in the constraint groove, the scraping seat on the seat can scrape the paste on the outer surface of the rotating roller. After scraping, the frictional resistance is restored from nonlinear and abrupt viscous resistance to linear and stable sliding or rolling friction. This can make the single-stroke lifting motion of the mounting plate more stable, avoid the phenomenon of jamming and crawling, and make the reciprocating motion of the mounting plate smoother. Especially in low-speed conditions, the motion control accuracy is higher. In addition, by scraping the outer surface of the roller, it can also prevent the roller surface from being scratched with deep grooves, thus extending the service life of the roller.

[0023] (2) This solution is equipped with an inner cavity and a filter cartridge. The scraped paste can enter the groove from the inclined surface on the scraper seat, enter the feed port from the groove, and be discharged into the filter cartridge from the discharge port. This avoids the situation where the paste impurities on the scraper seat re-contact the roller due to movement, and the paste impurities can be centrally stored. The filter cartridge can separate the grease in the paste from the paste impurities, which is convenient for subsequent professional recycling and treatment.

[0024] (3) This scheme is equipped with a pusher assembly and an eccentric block. When the rotating column rotates, the pusher assembly can drive the eccentric block to rotate in the movable groove. When the eccentric block rotates and the eccentric end contacts the lower surface of the blanking plate, it can push the free end of the blanking plate upward in the groove. When the eccentric block separates from the lower surface of the blanking plate, the force generated by the torsion spring drives the blanking plate to rotate and reset. By making the free end of the blanking plate move up and down in the groove, the paste-like impurities that enter the groove and fall on the blanking plate can be quickly fed into the feed port, thereby avoiding the paste-like impurities from staying in the groove for a long time; and realizing the rapid centralized recycling of the paste-like impurities scraped off the roller.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1 to 11 A stroke-triggered welding device includes a bracket 1, a mounting plate 3 slidably attached to one side of the bracket 1, a welding part 4 fixedly attached to one side of the mounting plate 3, and a motor 2 fixedly attached to one side of the bracket 1.

[0040] The welding part 4 includes a fixing plate 41 fixed to one side of the mounting plate 3, a cylinder 42 fixed to the fixing plate 41, a welding head 43 slidably connected to one side of the fixing plate 41 and whose upper end is fixed to the telescopic end of the cylinder 42, and a displacement sensor 44 fixed to the fixing plate 41.

[0041] The mounting plate 3 has a constraint groove 31 inside. A rotating disk 11 is rotatably connected to one side of the bracket 1, and a seat 12 is fixedly connected to one side of the rotating disk 11. A roller 13 is rotatably connected to one side of the seat 12, and the roller 13 is located in the constraint groove 31. A base 14 extending into the constraint groove 31 is also fixedly connected to one side of the mounting plate 3. The output shaft of the motor 2 is connected to the rotating disk 11.

[0042] It also includes a scraping assembly 5, which includes a scraper seat 51 fixed to one side of the base 12, an inclined surface disposed on the upper end of the scraper seat 51, a groove 52 opened on the inclined surface, a feed inlet 53 opened on the inner wall of the groove 52, an inner cavity 54 opened inside the scraper seat 51, a filter cartridge 57 rotatably connected to the inside of the scraper seat 51 and located in the inner cavity 54, and a discharge port 58 opened inside the scraper seat 51 and connecting the inner cavity 54 with the feed inlet 53.

[0043] The scraper seat 51 is also provided with an exhaust port 55 that communicates with the inner cavity 54, and a filter screen 56 is fixedly connected to the inner wall of the exhaust port 55. An air inlet connector 59 is fixedly connected to the outer surface of one side of the seat body 12, and a pipe connecting the exhaust port 55 and the air inlet connector 59 is provided inside the seat body 12.

[0044] A cover plate 18 is also fixedly connected to one side of the mounting plate 3. The cover plate 18 has a through hole, and a plug 181 is inserted into the through hole.

[0045] The scraper seat 51 is also provided with multiple oil drain grooves 7 connected to the inner cavity 54, an oil storage cavity 8 connected to the multiple oil drain grooves 7, and an oil drain port 9 connected to the oil storage cavity 8. The opening of the oil drain port 9 is located at the lower end of the scraper seat 51, and a sealing plug 91 is inserted into the opening of the oil drain port 9.

[0046] By adopting the above technical solution, the motor 2 drives the rotating disk 11 to rotate counterclockwise. The rotation of the rotating disk 11 drives the seat 12 and roller 13 to rotate. The roller 13 rotates clockwise due to contact and friction with the upper surface of the base 14. When the roller 13 rotates, it contacts the scraper seat 51, which scrapes off the material on the outer surface of the roller 13. The scraped material falls into the groove 52. The rotation of the seat 12 causes the position of the roller 13 in the constraint groove 31 to change, which drives the mounting plate 3 to slide downward on one side of the bracket 1. When the mounting plate 3 slides downward, it drives the welding part 4 to move downward, so that the welding head 43 is close to the workpiece. Then, the cylinder 42 is controlled to extend and drive the welding head 43 to descend. The welding head 43 then welds the workpiece. Welding; after welding, cylinder 42 drives welding head 43 to rise and reset, then motor 2 drives rotating disk 11 to rotate clockwise to reset, roller 13 contacts and rubs against the inner top wall of constraint groove 31 to rotate clockwise, scraper seat 51 continues to scrape the material on the surface of roller 13; after rotating disk 11 rotates clockwise to reset and drives scraper seat 51 to reset, the material in groove 52 enters inlet 53 and is discharged from outlet 58, the material discharged from outlet 58 falls into filter cartridge 57; cylinder 42 extends to drive welding head 43 to descend, welding head 43 welds the workpiece; after welding, cylinder 42 drives welding head 43 to rise, then motor 2 drives rotating disk 11 to rotate clockwise to reset. In position, the roller 13 rotates clockwise due to contact and friction with the inner top wall of the constraint groove 31, and the scraper seat 51 continues to scrape the material on the surface of the roller 13; after the rotating disk 11 rotates clockwise to reset and drives the scraper seat 51 to reset, the material in the groove 52 enters the feed port 53 and is discharged from the discharge port 58. The material discharged from the discharge port 58 falls into the filter cylinder 57; the grease in the material will flow through the filter cylinder 57 into the inner cavity 54, and flow along the inner wall of the inner cavity 54 into the oil drain groove 7, and from the oil drain groove 7 into the oil storage chamber 8. By pulling out the sealing plug 91, the grease in the oil storage chamber 8 can be discharged; by pulling out the plug 181 and connecting the air inlet connector 59 to the air pipe, the gas flows from the exhaust... The nozzle 55 sprays out impurities from inside the filter cartridge 57, which are then discharged through the through holes in the cover plate 18. The scraper seat 51 cleans the paste-like material on the outer surface of the rotating roller 13. After cleaning, the frictional resistance changes from nonlinear and abrupt viscous resistance to linear and stable sliding or rolling friction. This makes the single-stroke lifting motion of the mounting plate 3 smoother, avoids jamming and crawling, and makes the reciprocating motion of the mounting plate 3 smoother, especially at low speeds, resulting in higher motion control precision. Furthermore, by cleaning the outer surface of the roller 13, deep grooves are prevented from being scratched on the surface of the roller 13, extending the service life of the roller 13.

[0047] Please see Figures 3-5 , Figure 7 and Figure 11A side plate 511 is fixedly connected to one side of the scraper seat 51, and a discharge port 512 is opened inside the side plate 511. A synchronous wheel 61 is rotatably connected to one side of the side plate 511. One side of the synchronous wheel 61 is fixedly connected to one end of the filter cylinder 57, and the other end of the filter cylinder 57 is rotatably connected to the inner wall of the inner cavity 54. A drive unit 6 that drives the synchronous wheel 61 to rotate is also connected to one side of the seat body 12.

[0048] The drive unit 6 includes a hollow column 63 fixed to one side of the base 12, a rotating column 65 with one end rotatably connected to one side of the base 12 and the other end rotatably connected to the inner wall of the hollow column 63, a second synchronous pulley 66 fixed to the outer surface of the rotating column 65, a first synchronous belt 62 passing through the hollow column 63 and connecting the first synchronous pulley 61 and the second synchronous pulley 66, and a motor 64 fixed to one side of the hollow column 63, with the output shaft of the motor 64 passing through the hollow column 63 and fixed to one end of the rotating column 65.

[0049] By adopting the above technical solution, the motor 64 drives the rotating column 65 to rotate, the rotating column 65 drives the synchronous pulley 66 to rotate, and the synchronous pulley 66 drives the synchronous pulley 61 and the filter cartridge 57 to rotate through the synchronous belt 62. The rotation of the filter cartridge 57 generates centrifugal force to throw out the grease in the material. The grease thrown out by the filter cartridge 57 slides off the inner wall of the inner cavity 54 and flows into the oil drain trough 7, and enters the oil storage cavity 8 from the oil drain trough 7. This method can quickly reduce the oil content of the paste inside the filter cartridge 57. The remaining residue changes from greasy paste to relatively dry, loose particles or lumps. Its internal friction and flow resistance are greatly reduced. The remaining residue loses its stickiness and becomes loose, and can no longer stick together into a large clump. This makes it easier for the gas sprayed from the exhaust port 55 to blow the impurities inside the filter cartridge 57 out of the filter cartridge 57.

[0050] Please see Figures 9-11 The inner wall of the groove 52 is provided with a movable groove 15, and an eccentric block 16 is rotatably connected to the inner wall of the movable groove 15. The inner wall of the groove 52 is rotatably connected to a material discharge plate 17 (e.g., a torsion spring). Figure 10As shown, the two sides of one end of the material drop plate 17 are rotatably connected to the two sides of the inner wall of the groove 52, and a torsion spring is provided at the connection to drive the material drop plate 17 to reset. The scraper seat 51 is rotatably connected to a bevel gear 161 and a bevel gear 162 that is driven by the bevel gear 161. One side of the bevel gear 161 is fixedly connected to one side of the eccentric block 16. The seat body 12 and the scraper seat 51 are connected to a pusher assembly 10. The pusher assembly 10 includes a synchronous wheel 101 and a synchronous wheel 102 rotatably connected inside the seat body 12, a synchronous belt 103 connecting the synchronous wheel 101 and the synchronous wheel 102, a transmission rod 104 rotatably connected inside the scraper seat 51 and fixedly connected at one end to the synchronous wheel 102, and the bevel gear 162 is fixedly connected to the other end of the transmission rod 104. The rotating column 65 is rotatably connected to the seat body 12 and fixedly connected to the synchronous wheel 101.

[0051] By adopting the above technical solution, the rotation of the rotating column 65 can also drive the rotation of the synchronous pulley three 101. The rotation of the synchronous pulley three 101 drives the synchronous pulley four 102 and the transmission rod 104 to rotate through the synchronous belt two 103. The transmission rod 104 can also drive the rotation of the bevel gear two 162. The bevel gear two 162 drives the bevel gear one 161 and the eccentric block 16 to rotate. When the eccentric block 16 rotates in the movable groove 15, when the eccentric end of the eccentric block 16 contacts the lower surface of the blanking plate 17, it can push the free end of the blanking plate 17 upward in the groove 52. Increasing the tilt angle of the discharge plate 17 allows the material on the discharge plate 17 to quickly enter the feed inlet 53. After the eccentric block 16 separates from the lower surface of the discharge plate 17, the force generated by the torsion spring drives the discharge plate 17 to rotate and reset. By making the free end of the discharge plate 17 move up and down in the groove 52, the paste-like impurities that have entered the groove 52 and fallen on the discharge plate 17 can be quickly fed into the feed inlet 53, thereby avoiding the paste-like impurities from staying in the groove 52 for a long time. This achieves rapid and centralized recycling of the paste-like impurities scraped off the roller 13.

[0052] Please see Figure 7 and Figure 11 Two rollers 108 are provided between the side plate 511 and the seat 12, and the two ends of the rollers 108 are rotatably connected to the side plate 511 and the seat 12 respectively. A belt is sleeved on the outside of the two rollers 108, and a pusher flange 109 is fixedly connected to the outer surface of the belt. One end of one of the rollers 108 is fixedly connected to a synchronous pulley six 107. A synchronous pulley five 105 is fixedly connected to the outside of the transmission rod 104, and the synchronous pulley five 105 and the synchronous pulley six 107 are connected by a synchronous belt three 106. The synchronous pulley six 107 is rotatably connected inside the seat 12.

[0053] By adopting the above technical solution, the rotation of the rotating column 65 can also drive the rotation of the synchronous wheel 3 101. The rotation of the synchronous wheel 3 101 drives the rotation of the synchronous wheel 4 102 and the transmission rod 104 through the synchronous belt 2 103. The rotation of the transmission rod 104 drives the rotation of the synchronous wheel 5 105. The synchronous wheel 5 105 drives the rotation of the synchronous wheel 6 107 through the synchronous belt 3 106. The synchronous wheel 6 107 drives one of the rollers 108 to rotate. The rotation of one of the rollers 108 drives the other roller 108 and the belts outside the two rollers 108 to rotate. The material on the upper surface of the scraper seat 51 is quickly pushed into the groove 52 by the pusher flange 109 on the surface of the belt, which promotes the rapid movement of the material on the upper surface of the scraper seat 51 and improves the efficiency of centralized recycling and processing of the material.

[0054] How to use:

[0055] S1. Motor 2 drives rotating disk 11 to rotate counterclockwise. The rotation of rotating disk 11 drives seat 12 and roller 13 to rotate. Roller 13 rotates clockwise due to contact and friction with the upper surface of base 14. When roller 13 rotates, it will contact scraper seat 51. Scraper seat 51 scrapes off the material on the outer surface of roller 13. The scraped material falls into groove 52. The rotation of seat 12 causes roller 13 to change position in constraint groove 31, which drives mounting plate 3 to slide downward on one side of bracket 1. When mounting plate 3 slides downward, it drives welding part 4 to move downward, so that welding head 43 is close to workpiece.

[0056] S2, the cylinder 42 extends and drives the welding head 43 to descend, and the welding head 43 welds the workpiece; after welding, the cylinder 42 drives the welding head 43 to rise, and then the motor 2 drives the rotating disk 11 to rotate clockwise to reset, the roller 13 contacts and rubs against the inner top wall of the constraint groove 31 to rotate clockwise, and the scraper seat 51 continues to scrape the material on the surface of the roller 13; after the rotating disk 11 rotates clockwise to reset and drives the scraper seat 51 to reset, the material in the groove 52 enters the feed port 53 and is discharged from the discharge port 58, and the material discharged from the discharge port 58 falls into the filter cartridge 57;

[0057] S3. Motor 64 drives rotating column 65 to rotate, rotating column 65 drives synchronous pulley 66 to rotate, synchronous pulley 66 drives synchronous pulley 61 and filter cartridge 57 to rotate via synchronous belt 62. The rotation of filter cartridge 57 generates centrifugal force to throw out the grease in the material. The grease thrown out by filter cartridge 57 slides down the inner wall of cavity 54 and flows into oil drain 7. It enters oil storage chamber 8 from oil drain 7. By pulling out sealing plug 91, the grease in oil storage chamber 8 can be discharged. By pulling out plug 181 and connecting air inlet connector 59 to air pipe, gas is sprayed out from exhaust port 55, blowing out impurities inside filter cartridge 57 through the through hole in cover plate 18.

[0058] S4. The rotation of the rotating column 65 can also drive the rotation of the synchronous pulley 3 101. The rotation of the synchronous pulley 3 101 drives the synchronous pulley 4 102 and the transmission rod 104 to rotate through the synchronous belt 2 103.
