Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a welding equipment for manufacturing interior door handles. Background Technology

[0002] With the continuous development of the automotive industry, the requirements for component quality, production efficiency, and cost control are increasing. As a crucial component of automotive interiors, the manufacturing of door handles demands high precision, efficiency, and stability from welding equipment. Welding equipment includes electric welding machines and flame welding equipment. In the automotive manufacturing field, common types include ultrasonic handheld welding machines, hot melt welding machines, and laser welding machines. Some equipment features functions such as voltage protection, overload protection, overcurrent protection, automatic power supply frequency compensation, and automatic frequency tracking. The ultrasonic power is adjustable, and a computer-programmed, graded soft-start mode triggers the ultrasonic waves, resulting in more ideal welding effects for plastic parts. Traditional welding methods, such as edge-sealing and pressing techniques, have shortcomings, such as easy aging of adhesives and poor durability. Laser spiral welding can increase the joint area, suppress deformation of the door opening, improve the rigidity of the body, allow for gaps between plates, enable rapid welding, shorten the welding spacing, and offer high flexibility in joint configuration. It can be used with CNC welding power supplies, intelligent welding machines, fully automatic special welding machines, and flexible welding robot workstations to achieve CNC, automation, and intelligence in welding production. New welding processes and equipment are constantly being developed to improve the welding quality and production efficiency of the door handles and reduce costs.

[0003] Traditional welding methods are simple and require ultrasonic welding after laser welding, necessitating the transfer of parts. This transfer process increases positioning errors and lacks effective support for complex curved surfaces, resulting in low positioning efficiency. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a welding equipment for manufacturing interior door handles, comprising an equipment base plate, an equipment bracket fixedly connected to the bottom of the equipment base plate, a welding machine device fixedly connected to one side of the top of the equipment base plate, a fixing device fixedly connected to the top of the equipment base plate, and the welding machine device being positioned above the fixing device.

[0005] The welding machine device includes a first telescopic rod, with a welding bracket fixedly connected to the movable end of the first telescopic rod. A first motor is fixedly connected to the top of the welding bracket. A fixed seat is sleeved and fixedly connected to the drive shaft of the first motor. A laser module is fixedly connected to the bottom of the fixed seat. A fixed plate is sleeved and fixedly connected to the side of the laser module. A first spring rod is slidably connected through the bottom of the fixed plate. An ultrasonic welding head is fixedly connected to the bottom of the first spring rod. The fixed end of the first telescopic rod is fixedly connected to the top of the equipment base plate. Activating the first telescopic rod causes the welding bracket to rise or fall. Activating the first motor causes the fixed seat to rotate, which in turn rotates the laser module. The rotation of the laser module causes the fixed plate to rotate, which in turn moves the first spring rod. This movement, in turn, moves the ultrasonic welding head, allowing the inner handle to undergo ultrasonic welding. The ultrasonic welding head welds specific positions on the handle surface. After welding, the ultrasonic welding head stops moving, providing support and positioning for the first spring rod. This ensures the laser module maintains a stable position during welding, improving welding accuracy. The first spring rod also absorbs the vibration of the ultrasonic welding head, preventing it from affecting the welding accuracy of the laser module. Furthermore, the spring force of the first spring rod stabilizes the position of the part, ensuring its stability during welding and further enhancing welding precision.

[0006] Preferably, the fixing device includes an upper top plate, the top of which has a straight sliding groove, and a lower bottom plate rotatably connected to the bottom of the upper top plate. The top of the lower bottom plate has an arc-shaped sliding groove, the inner wall of which is slidably connected to a sliding assembly. A support device is rotatably connected to the top of the sliding assembly, and a positioning assembly is fixedly connected to the side of the support device. A pneumatic assembly is fixedly connected to the top of the upper top plate, and the movable end of an electric worm gear device is fixedly connected to the side of the upper top plate. The fixed end of the electric worm gear device is fixedly connected to the side of the lower bottom plate, and the bottom of the lower bottom plate is fixedly connected to the top of the equipment base plate via a bracket. The electric worm gear... The lever device, an electric worm gear mechanism, rotates, causing relative rotation between the upper top plate and the lower bottom plate. The upper top plate and the lower bottom plate drive the straight and arc-shaped sliding grooves to slide relative to each other, thereby causing the hollow shaft cylinder to slide along the straight and arc-shaped sliding grooves. This allows the sliding base to slide along the top of the upper top plate via a sliding strip, thus clamping and positioning the part from multiple directions. Under the transmission of the electric worm gear mechanism, the part moves to a designated position and remains in a fixed position, ensuring processing quality. The position of the hollow shaft cylinder is limited by upper and lower limit rings. Compared with traditional fixing methods, this method increases the positioning capability for complex curved surface parts, enabling rapid positioning of the inner handle.

[0007] Preferably, the sliding assembly includes a sliding base, with slide bars fixedly connected to both sides of the bottom of the sliding base, a limit plate fixedly connected to the top of the sliding base, a rotating shaft fixedly connected to one side of the top of the sliding base, a hollow shaft cylinder fixedly connected to the bottom of the sliding base, an upper limit ring sleeved and fixedly connected to the side of the hollow shaft cylinder, and a lower limit ring fixedly connected to the bottom of the side of the hollow shaft cylinder. The hollow shaft cylinder is slidably connected to the side of the arc-shaped slide groove through the upper limit ring.

[0008] Preferably, the support device includes a support base, a limiting rack is fixedly connected to the top of the support base, a sliding seat is slidably connected to the side of the limiting rack, a hollow pull rod is fixedly connected to the side of the sliding seat, a first spring is sleeved and slidably connected to the side of the hollow pull rod, a fixed end of a spring hydraulic rod is fixedly connected to the side of the sliding seat, the fixed end of the spring hydraulic rod is connected to an oil supply pipe, the bottom of the support base is rotatably connected to the top of the sliding base through a rotating shaft, and the side of the spring hydraulic rod is fixedly connected to the side of the positioning component.

[0009] Preferably, the positioning assembly includes a positioning seat, a brake gear rotatably connected to the side of the positioning seat, a spring rod fixedly connected to the side of the brake gear, a suction cup fixedly connected to the side of the spring rod, a limit post fixedly connected to the inner wall of the suction cup, and a side of the positioning seat fixedly connected to the movable end of the spring hydraulic rod. A sliding base drives a support base to move, the support base drives a sliding seat to move, and the sliding seat moves the spring hydraulic rod, thereby elastically positioning the side of the part. The positioning and elasticity of the spring hydraulic rod absorb the vibration generated by the first spring rod, thus preventing displacement of the part during welding. When the part position is different, the first spring is pulled, causing the sliding seat to move away from the spring hydraulic rod. The pressure rod changes the pointing height of the spring-hydraulic rod, ensuring clamping stability. The compression deformation of the spring-hydraulic rod causes the hydraulic oil to change direction along the oil supply pipe, thus achieving a fixed linkage. The spring-hydraulic rod moves the positioning seat, which in turn moves the brake gear. The brake gear then moves the spring rod, which in turn moves the suction cup. The suction cup positions the side of the part for fixation. Limiting posts prevent displacement during compression positioning. The elasticity of the spring rod provides adaptive fixation of the part, and the fixation of the spring rod also fixes the brake gear, allowing multiple sets of brake gears to mesh and brake, maintaining a stable and fixed state, thus ensuring the quality of the clamping.

[0010] Preferably, the pneumatic assembly includes a ventilation duct, a second motor is fixedly connected to the inner wall of the ventilation duct via a bracket, a lower fan blade is fixedly connected to the top of the second motor, a lower gear ring meshes with the top of the lower fan blade, a reversing gear meshes with the top of the lower gear ring, a fixed shaft is rotatably connected to the side of the reversing gear, an upper gear ring meshes with the top of the reversing gear, an upper fan blade is fixedly connected to the top of the upper gear ring, a support assembly is fixedly connected to the top of the ventilation duct, the bottom of the ventilation duct is fixedly connected to the top of the equipment base plate, and the side of the support assembly penetrates the top of the lower base plate and is rotatably connected to the lower base plate.

[0011] Preferably, the support assembly includes an oil reservoir with an oil inlet pipe connected to its side, an air outlet fixedly connected to its bottom, a sliding cylinder slidably connected to its inner wall, a support cylinder connected to its top, a support mesh fixedly connected to its top, and the bottom of the air outlet fixedly connected to the top of the ventilation pipe. The side of the oil reservoir penetrates the top of the upper top plate and is rotatably connected to it. The side of the oil reservoir also penetrates the top of the lower bottom plate and is rotatably connected to it. A second motor rotates, driving the lower fan blades to rotate. The rotation of the lower fan blades drives the lower gear ring to rotate, which in turn drives the reversing gear to rotate. The upper gear ring rotates, which in turn drives the upper fan blades to rotate. This, in turn, draws air from the top of the ventilation duct to the bottom, thus providing pneumatic cooling and cleaning of the parts' surfaces. This ensures welding quality and timely cooling, preventing thermal deformation after welding that could affect the overall quality. Hydraulic oil flows through the inlet pipe, moving the sliding cylinder to position the parts from the side and bottom, facilitating placement. The cylinder can also be adjusted to different heights to support parts of varying sizes, providing stable support during the ultrasonic welding process.

[0012] This invention provides a welding device for manufacturing interior door handles. It has the following advantages:

[0013] 1. The welding equipment used in the manufacturing of the interior door handle includes a first telescopic rod. This first telescopic rod raises or lowers the welding bracket, activating a first motor. The rotation of the first motor rotates the fixed base, which in turn rotates the laser module. The rotation of the laser module rotates the fixed plate, which in turn moves the first spring rod. This, in turn, moves the ultrasonic welding head, allowing the interior door handle to undergo ultrasonic welding. The ultrasonic welding head welds specific locations on the handle surface. After welding, the ultrasonic welding head stops moving, providing support and positioning for the first spring rod. This ensures the laser module remains in a stable position during welding, improving welding accuracy. Furthermore, the first spring rod absorbs the vibration of the ultrasonic welding head, preventing it from affecting the welding accuracy of the laser module. The spring force of the first spring rod also stabilizes the position of the part, ensuring stability during welding and further enhancing welding accuracy.

[0014] 2. The welding equipment used in the manufacturing of the interior door handle is equipped with an electric worm gear device. The rotation of the electric worm gear device causes relative rotation between the upper top plate and the lower bottom plate. The upper top plate and the lower bottom plate drive the straight slide groove and the arc slide groove to slide relative to each other, thereby driving the hollow shaft cylinder to slide along the straight slide groove and the arc slide groove. This causes the sliding base to slide along the top of the upper top plate through the slide bar, thereby clamping and positioning the part from multiple directions. Under the transmission of the electric worm gear device, the part moves to a designated position and is held in a fixed position, thus ensuring the processing quality. The position of the hollow shaft cylinder is limited by the upper limit ring and the lower limit ring. Compared with the traditional fixing method, this method increases the positioning of parts with complex curved surfaces, thereby enabling the interior handle to be positioned quickly.

[0015] 3. The welding equipment used in the manufacturing of the interior door handle is equipped with a sliding base. The sliding base moves the support base, which in turn moves the sliding seat. The sliding seat moves the spring-hydraulic rod, thereby elastically positioning the side of the part. The positioning and elasticity of the spring-hydraulic rod absorb the vibration generated by the first spring rod, thus preventing displacement of the part during welding. When the part position is different, the first spring is pulled, causing the sliding seat to move away from the spring-hydraulic rod, thereby changing the pointing height of the spring-hydraulic rod and ensuring clamping stability. The compression deformation of the spring-hydraulic rod causes the hydraulic oil to change direction along the oil supply pipe, thus achieving a fixed linkage. The spring-hydraulic rod moves the positioning seat, which in turn moves the brake gear, which in turn moves the spring rod, which in turn moves the suction cup. The suction cup positions and fixes the side of the part. The setting of the limit post prevents displacement during compression positioning. At the same time, the elasticity of the spring rod provides adaptive fixation of the part, and after the spring rod is fixed, it fixes the brake gear, thereby enabling multiple sets of brake gears to mesh and brake, maintaining a stable and fixed state and ensuring the quality of the work.

[0016] 4. The welding equipment used in the manufacturing of the car door handle is equipped with a second motor. The rotation of the second motor drives the lower fan blade to rotate, which in turn drives the lower gear ring to rotate. The rotation of the lower gear ring drives the reversing gear to rotate, which in turn drives the upper gear ring to rotate. The rotation of the upper gear ring drives the upper fan blade to rotate, thereby driving air to be transferred from the top to the bottom of the ventilation duct. This allows for pneumatic cooling and cleaning of the surface of the parts, ensuring welding quality and timely cooling. This prevents thermal deformation after hot welding from affecting the welding quality. Hydraulic oil from the oil supply pipe flows through the oil inlet pipe, which drives the sliding cylinder to move. This allows for positioning of the parts from the side and bottom, facilitating the placement of the parts. The height can be adjusted according to the different sizes of the parts, thus providing support for parts of different sizes and providing stable support for the parts during the ultrasonic welding stage.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-2 The present invention provides a technical solution: a welding equipment for manufacturing interior door handles, including an equipment base plate 1, an equipment bracket 2 fixedly connected to the bottom of the equipment base plate 1, a welding machine device 3 fixedly connected to one side of the top of the equipment base plate 1, a fixing device 4 fixedly connected to the top of the equipment base plate 1, and the welding machine device 3 being positioned above the fixing device 4.

[0028] The equipment base plate 1 and equipment bracket 2 provide overall support for the equipment. The welding machine device 3 moves the welding module and integrates ultrasonic welding and laser welding modules to perform systematic welding on the inner handle, shortening the processing flow. The inner handle is fixed by the fixing device 4, and the corresponding components of the fixing device 4 are used to position complex parts, thereby completing the positioning during welding and ensuring welding efficiency. The pneumatic components are used for cooling during welding to ensure welding quality. The welding quality is guaranteed after welding is completed.

[0029] The welding machine device 3 includes a first telescopic rod 301. A welding bracket 302 is fixedly connected to the movable end of the first telescopic rod 301. A first motor 303 is fixedly connected to the top of the welding bracket 302. A fixed seat 304 is sleeved and fixedly connected to the drive shaft of the first motor 303. A laser module 305 is fixedly connected to the bottom of the fixed seat 304. A fixed plate 306 is sleeved and fixedly connected to the side of the laser module 305. A first spring rod 307 is slidably connected through the bottom of the fixed plate 306. An ultrasonic welding head 308 is fixedly connected to the bottom of the first spring rod 307. The fixed end of the first telescopic rod 301 is fixedly connected to the top of the equipment base plate 1.

[0030] The first telescopic rod 301 is activated, causing the welding bracket 302 to rise or fall. The first motor 303 is also activated, rotating the fixed base 304, which in turn rotates the laser module 305. The laser module 305 rotates, causing the fixed plate 306 to rotate. The fixed plate 306 then moves the first spring rod 307, which in turn moves the ultrasonic welding head 308. This allows the inner handle to undergo ultrasonic welding first, with the ultrasonic welding head 308 welding specific positions on the handle surface. After welding, the ultrasonic welding head 308 stops moving, providing support and positioning for the first spring rod 307. This ensures the laser module 305 remains in a stable position during welding, improving welding accuracy. The first spring rod 307 also absorbs the vibration of the ultrasonic welding head 308, preventing it from affecting the welding accuracy of the laser module 305. Furthermore, the spring force of the first spring rod 307 stabilizes the position of the part, ensuring stability during welding and further improving welding accuracy.

[0031] Please see Figures 1-4The present invention provides a technical solution: the fixing device 4 includes an upper top plate 401, a straight sliding groove 402 is provided on the top of the upper top plate 401, a lower bottom plate 403 is rotatably connected to the bottom of the upper top plate 401, an arc-shaped sliding groove 404 is provided on the top of the lower bottom plate 403, a sliding component 405 is slidably connected to the inner wall of the arc-shaped sliding groove 404, a support device 406 is rotatably connected to the top of the sliding component 405, a positioning component 407 is fixedly connected to the side of the support device 406, a pneumatic component 408 is fixedly connected to the top of the upper top plate 401, the movable end of an electric worm gear device 409 is fixedly connected to the side of the upper top plate 401, the fixed end of the electric worm gear device 409 is fixedly connected to the side of the lower bottom plate 403, and the bottom of the lower bottom plate 403 is fixedly connected to the top of the equipment base plate 1 through a bracket.

[0032] The sliding assembly 405 includes a sliding base 4051, with slide bars 4052 fixedly connected to both sides of the bottom of the sliding base 4051, a limit plate 4053 fixedly connected to the top of the sliding base 4051, a rotating shaft 4054 fixedly connected to one side of the top of the sliding base 4051, a hollow shaft cylinder 4055 fixedly connected to the bottom of the sliding base 4051, an upper limit ring 4056 sleeved and fixedly connected to the side of the hollow shaft cylinder 4055, a lower limit ring 4057 fixedly connected to the bottom side of the hollow shaft cylinder 4055, and the hollow shaft cylinder 4055 slidably connected to the side of the arc-shaped slide groove 404 through the upper limit ring 4056.

[0033] The electric worm gear device 409 is activated, and its rotation causes the upper top plate 401 and the lower bottom plate 403 to rotate relative to each other. The upper top plate 401 and the lower bottom plate 403 drive the straight slide groove 402 and the arc slide groove 404 to slide relative to each other, thereby driving the hollow shaft cylinder 4055 to slide along the straight slide groove 402 and the arc slide groove 404. This causes the sliding base 4051 to slide along the top of the upper top plate 401 via the slide bar 4052, thereby clamping and positioning the part from multiple directions. Under the transmission of the electric worm gear device 409, the part moves to a designated position and remains in a fixed position, thereby ensuring the processing quality. The upper limit ring 4056 and the lower limit ring 4057 limit the position of the hollow shaft cylinder 4055. Compared with the traditional fixing method, this method increases the positioning of complex curved surface parts, thereby enabling the inner handle to be positioned quickly.

[0034] Please see Figures 1-6The present invention provides a technical solution: the support device 406 includes a support base 4061, a limiting rack 4062 is fixedly connected to the top of the support base 4061, a sliding seat 4063 is slidably connected to the side of the limiting rack 4062, a hollow pull rod 4064 is fixedly connected to the side of the sliding seat 4063, a first spring 4065 is sleeved and slidably connected to the side of the hollow pull rod 4064, a fixed end of a spring hydraulic rod 4066 is fixedly connected to the side of the sliding seat 4063, the fixed end of the spring hydraulic rod 4066 is connected to an oil supply pipe 4067, the bottom of the support base 4061 is rotatably connected to the top of the sliding base 4051 through a rotating shaft 4054, and the side of the spring hydraulic rod 4066 is fixedly connected to the side of the positioning component 407.

[0035] The positioning assembly 407 includes a positioning seat 4071, a brake gear 4072 rotatably connected to the side of the positioning seat 4071, a spring rod 4073 fixedly connected to the side of the brake gear 4072, a suction cup 4074 fixedly connected to the side of the spring rod 4073, a limit post 4075 fixedly connected to the inner wall side of the suction cup 4074, and the side of the positioning seat 4071 fixedly connected to the movable end side of the spring hydraulic rod 4066.

[0036] The sliding base 4051 drives the support base 4061 to move, which in turn drives the sliding seat 4063 to move. The movement of the sliding seat 4063 then drives the spring-hydraulic rod 4066 to move, thus providing elastic positioning of the part's side. The positioning and elasticity of the spring-hydraulic rod 4066 absorb the vibration generated by the first spring rod 307, preventing displacement of the part during welding. When the part's position changes, the first spring 4065 is pulled, causing the sliding seat 4063 to move away from the spring-hydraulic rod 4066, thereby changing the pointing height of the spring-hydraulic rod 4066 and ensuring stable clamping. The compression deformation of the spring-hydraulic rod 4066 also causes the hydraulic oil to change direction along the oil supply pipe 4067. This allows for a fixed linkage. The spring hydraulic rod 4066 drives the positioning seat 4071 to move, which in turn drives the brake gear 4072 to move. The brake gear 4072 then drives the spring rod 4073 to move, which in turn drives the suction cup 4074 to move. The suction cup 4074 positions the side of the part for fixation. The setting ratio of the limit post 4075 prevents displacement during compression positioning. At the same time, the elasticity of the spring rod 4073 provides adaptive fixation for the part. After the spring rod 4073 is fixed, it also fixes the brake gear 4072, thereby enabling multiple sets of brake gears 4072 to mesh and brake, maintaining a stable and fixed state and ensuring the quality of the fixation.

[0037] Please see Figures 1-8The present invention provides a technical solution: the pneumatic component 408 includes a ventilation pipe 4081, a second motor 4082 is fixedly connected to the inner wall of the ventilation pipe 4081 by a bracket, a lower fan blade 4083 is fixedly connected to the top of the second motor 4082, a lower gear ring 4084 is meshed with the top of the lower fan blade 4083, a reversing gear 4085 is meshed with the top of the lower gear ring 4084, a fixed shaft 4086 is rotatably connected to the side of the reversing gear 4085, an upper gear ring 4087 is meshed with the top of the reversing gear 4085, an upper fan blade 4088 is fixedly connected to the top of the upper gear ring 4087, a support component 4089 is fixedly connected to the top of the ventilation pipe 4081, the bottom of the ventilation pipe 4081 is fixedly connected to the top of the equipment base plate 1, and the side of the support component 4089 penetrates the top of the lower base plate 403 and is rotatably connected to the lower base plate 403.

[0038] The support assembly 4089 includes an oil reservoir 40891, an oil inlet pipe 40892 connected to the side of the oil reservoir 40891, an air outlet 40893 fixedly connected to the bottom of the oil reservoir 40891, a sliding cylinder 40894 slidably connected to the inner wall of the oil reservoir 40891, a support cylinder 40895 connected to the top of the sliding cylinder 40894, a support net 40896 fixedly connected to the top of the support cylinder 40895, the bottom of the air outlet 40893 fixedly connected to the top of the ventilation pipe 4081, the side of the oil reservoir 40891 penetrating the top of the upper top plate 401 and rotatably connected to the upper top plate 401, and the side of the oil reservoir 40891 penetrating the top of the lower bottom plate 403 and rotatably connected to the lower bottom plate 403.

[0039] The second motor 4082 is started, and its rotation drives the lower fan blade 4083 to rotate. The rotation of the lower fan blade 4083 drives the lower gear ring 4084 to rotate, which in turn drives the reversing gear 4085 to rotate. The rotation of the reversing gear 4085 drives the upper gear ring 4087 to rotate, which in turn drives the upper fan blade 4088 to rotate. This drives air to be transferred from above to below the ventilation pipe 4081, thereby providing pneumatic cooling and cleaning of the surface of the parts. This ensures welding quality and timely cooling, preventing thermal deformation after hot welding from affecting the welding quality. The hydraulic oil in the oil supply pipe 4067 flows through the oil inlet pipe 40892, which drives the sliding cylinder 40894 to move. This allows for both side and bottom positioning of the parts, facilitating placement and allowing for height adjustment according to different part sizes. This provides support for parts of different sizes and provides stable support during the ultrasonic welding stage.
