Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and in particular to an automated welding equipment for processing household electrical appliances. Background Art

[0002] Ultrasonic welding equipment is widely used in household appliance housings, packaging, auto parts, fishing gear and other industries. It is often used for welding plastic parts. The ultrasonic energy is transmitted to the welding area through the upper weldment. Since the welding area, that is, the interface between the two welds, has a large acoustic impedance, local high temperature will be generated and accumulated in the welding area, causing the contact surface of the two plastics to melt rapidly. After a certain amount of pressure is applied, they are fused into one. The welding strength can be close to the strength of the raw material itself.

[0003] Current welding equipment, such as the ultrasonic welding equipment disclosed in Chinese Patent Publication No. CN117444525B, fuses the plastic casings of household appliances using localized high temperatures. However, after welding, the products must be collected and cooled. During automated transportation, the connection area often remains cold, leading to some degree of deformation and misalignment. Accordingly, the present invention provides automated welding equipment for household appliance processing. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an automated welding device for processing household appliances.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: An automated welding device for processing household appliances comprises a mobile base, a mounting block, a support frame and a fixed frame, wherein the mounting block is fixedly arranged on the top of the mobile base, and a welding piece is fixedly arranged on the top of the mounting block; The welding part is composed of a lifting part and a welding part, and the welding part is pushed to slide vertically by the lifting part sliding up and down; The top of the mobile base is fixedly connected to two support frames, and an automatic clamping member is provided between the two support frames. The automatic clamping member consists of a regulating part and a clamping part. The automatic clamping member drives the regulating part to slide vertically up and down and horizontally left and right through electricity. The clamping part drives the clamping part to move and clamp the home appliance in multiple directions through the four-way sliding of the regulating part. A fixed frame is fixed on the top of the mobile base, and an upper groove and a lower groove are respectively opened on the fixed frame, wherein a transmission part is set inside the upper groove, and the transmission part automatically transports the welded home appliances through the continuous rotation of two rollers; A cooling part is provided inside the lower groove, which consists of an air cooling part and a liquid cooling part. The air cooling part cools the product on the transmission part by continuously blowing air, and the liquid cooling part continuously injects coolant into the metal pipe through piston movement to quickly cool the air flow blown out by the air cooling part.

[0006] Preferably, the lifting part includes a support column, a gear plate and a lifting ring, wherein the lifting ring and the gear plate are meshed and connected, and the lifting part rotates the driving handle on the lifting ring so that the lifting ring can slide vertically up and down along the support column.

[0007] Preferably, the regulating part includes a first sliding rod, a first electric slider, a guide rod and a second electric slider. The regulating part drives the clamping part to adjust and move up and down by the first electric slider sliding vertically along the first sliding rod, and the regulating part drives the clamping part to adjust and move left and right by the second electric slider sliding horizontally along the guide rod.

[0008] Preferably, the transmission part includes a first conveying roller, a second conveying roller and a conveyor belt, wherein the first conveying roller and the second conveying roller are sleeved and connected to each other in synchronous rotation via the conveyor belt.

[0009] Preferably, the conveyor belt is a thin and light belt with high friction force, and a plurality of ventilation mesh holes are provided on the conveyor belt, so that the air flow of the air cooling part can cool the product through the ventilation mesh holes.

[0010] Preferably, the air cooling part includes an air jet hole and an air pump. The air cooling part quickly impacts the air flow into the air jet hole through the air pump, and cools the products on the transmission part through the air flow ejected from the air jet hole.

[0011] Preferably, the liquid cooling part continuously injects cooling liquid into the bent metal tube through piston movement to cool the metal tube, wherein the airflow ejected from the jet hole in the air cooling part passes through the bent metal tube cooled by the liquid cooling part to cool it.

[0012] Preferably, the bent metal tube in the liquid cooling part is placed transversely between the transmission part and the air cooling part, and the metal tube is fixedly arranged inside the upper groove and above the air injection hole.

[0013] The present invention has the following beneficial effects: 1. By setting up a cooling component, the air cooling part and the liquid cooling part in the cooling component work together to form an efficient cooling system. The liquid cooling part continuously injects coolant into the bent metal tube through piston movement to quickly reduce the temperature of the metal tube. The air pump in the air cooling part sends the air flow into the air jet hole. The ejected air flow is cooled again when passing through the cooled metal tube. Then, the product is cooled in all directions through the ventilation mesh of the conveyor belt. This process not only has high cooling efficiency, but also has a reasonable air flow path design, ensuring that all parts of the product can be fully cooled, effectively preventing the product from deformation due to high temperature after welding, and ensuring product quality.

[0014] 2. By setting up a transmission part, the first transmission roller, the second transmission roller and the conveyor belt sleeve rotate synchronously to form a stable transmission structure. The conveyor belt is made of a light, thin and high-friction material, which not only ensures that the product will not slip due to insufficient friction during transmission, but also reduces the energy consumption caused by its own weight. At the same time, the design of the ventilation mesh provides convenient conditions for air cooling without affecting the transmission stability, so that the product can be cooled synchronously during the transmission process, realizing the efficient combination of transmission and cooling, and ensuring the continuity of the production process.

[0015] 3. By setting up an automatic clamping part, the control part in the automatic clamping part is driven by the power of the first electric slider and the second electric slider to achieve vertical and horizontal sliding, driving the clamping part to perform multi-directional mobile clamping of home appliances. This automated clamping process replaces traditional manual positioning and fixing operations, reduces manual intervention links, not only reduces the error rate of manual operation, improves the consistency of product welding, but also saves labor costs.

[0016] 4. By setting up the welding parts, the lifting part in the welding parts adopts a combination design of support columns, tooth plates and lifting collars. By turning the driving handle and utilizing the principle of gear meshing, the lifting collar can slide vertically along the support column, thereby pushing the welding part up and down. This mechanical transmission method is simple and intuitive to operate, and can accurately control the height of the welding part, adapting to the welding needs of household appliances of different height specifications.

The transmission part automatically transports the welded home appliances through the continuous rotation of two rollers. A cooling part is provided inside the lower groove, which consists of an air cooling part and a liquid cooling part. The air cooling part cools the product on the transmission part by continuously blowing air, and the liquid cooling part continuously injects coolant into the metal pipe through piston movement to quickly cool the air flow blown out by the air cooling part. Example 1:

[0022] The regulating part includes a first slide bar 10, a first electric slider 11, a guide rod 13 and a second electric slider 14. The regulating part drives the clamping part to adjust and move up and down by the first electric slider 11 sliding vertically along the first slide bar 10, and drives the clamping part to adjust and move left and right by the second electric slider 14 sliding horizontally along the guide rod 13.

[0023] Among them, the support column 3 is fixedly connected to the top of the mounting block 2, the tooth plate 4 is fixedly connected to one side of the support column 3, one side of the lifting ring 5 is fixedly connected to the sliding frame 6, and a welder 7 is fixedly provided on the sliding frame 6.

[0024] In addition, a first fixed plate 9 is fixedly connected between the two support frames 8, wherein two first sliding rods 10 are fixedly connected to one side of the first fixed plate 9, and two first electric sliders 11 are respectively slidably connected to the two first sliding rods 10, and a second fixed plate 12 is fixedly connected to one side of the two first electric sliders 11, and a guide rod 13 is fixedly provided on one side of the second fixed plate 12, and a second electric slider 14 is slidably connected through the guide rod 13, and a second sliding rod 15 is fixedly connected to one side of the second fixed plate 12, and a sliding plate 16 slidably connected to the second sliding rod 15 is fixedly connected to one side of the second electric slider 14, and an electric clamping arm 17 is fixedly provided on the sliding plate 16.

[0029] The conveyor belt 22 is a thin and light belt with high friction force. A plurality of ventilation mesh holes are provided on the conveyor belt 22 so that the air flow of the air cooling part can cool the product through the ventilation mesh holes.

[0030] An extrusion base 18 is fixedly connected to the top of the mobile base 1 .

[0031] Among them, one side of the upper groove is rotatably connected to the first conveying roller 20, and the other side of the upper groove is rotatably connected to the second conveying roller 21. A motor 23 is fixedly installed on one side of the fixed frame 19, and the positioning drive end of the motor 23 is fixedly connected to the first conveying roller 20.

[0032] In this embodiment, the motor 23 is started. When the welding of the product on the extrusion base 18 is completed, it is clamped to the transmission belt 22 through the electric clamping arm 17. At this time, the motor 23 drives the first conveyor roller 20 to rotate, and then drives the conveyor belt 22 to rotate, thereby transmitting the product thereon horizontally. Example 3:

[0033] Reference Figures 6-10 The air cooling part includes an air jet hole 25 and an air pump 26. The air cooling part quickly impacts the air flow into the air jet hole 25 through the air pump 26, and the air flow ejected from the air jet hole 25 is used to cool the products on the transmission part.

[0034] The liquid cooling part continuously injects coolant into the bent metal tube through piston movement to cool the metal tube, wherein the air flow ejected from the jet hole 25 in the air cooling part passes through the bent metal tube cooled by the liquid cooling part to cool it.

[0035] The bent metal tube in the liquid cooling part is placed transversely between the transmission part and the air cooling part. The metal tube is fixed inside the upper groove and located above the air injection hole 25 .

[0036] Among them, a middle partition 24 is fixedly set between the fixed frames 19, a number of air injection holes 25 are evenly opened on the middle partition 24, an air pump 26 is fixedly set inside the lower groove, and a buffer chamber 27 connected to the air injection holes 25 is fixedly set at the bottom of the middle partition 24, and the buffer chamber 27 and the air pump 26 are connected to each other through two air guide tubes 28.

[0037] In addition, one side of the fixed frame 19 is rotatably connected to the first bevel gear 29 fixedly connected to the first conveying roller 20, one side of the fixed frame 19 is fixedly connected to the fixed block 30, one side of the fixed block 30 is rotatably connected to the second bevel gear 31, and the other side of the fixed block 30 is rotatably connected to the reciprocating screw 32 fixedly connected to the second bevel gear 31, a ball nut 33 is threadedly sleeved on the reciprocating screw 32, one side of the ball nut 33 is fixedly connected to two push rods 34, one side of the fixed frame 19 is fixedly connected to the first water tank 35, and one side of the push rod 34 is fixedly connected to the piston 36 connected to the sliding piston between the first water tank 35.

[0038] One side of the first water tank 35 is fixedly connected to a liquid cooling pipe 37, which passes through the fixed frame 19 and extends to the inside of the upper groove. A cooler 38 is fixedly provided on one side of the fixed frame 19. The other end of the liquid cooling pipe 37 extends to the outside of the fixed frame 19 and is connected to the cooler 38. One side of the fixed frame 19 is fixedly connected to a second water tank 39. The first water tank 35 and the second water tank 39 are connected by a water pumping pipe 40, and the second water tank 39 and the cooler 38 are connected by a connecting pipe 41.

[0039] In this embodiment, after the air pump 26 in the lower groove is started, the air is compressed and transported to the buffer chamber 27 through two air ducts 28. The buffer chamber 27 is connected to the air jet hole 25. Its function is to buffer and evenly distribute the compressed air in the cavity to avoid the situation where direct air supply causes uneven air flow. The air flow after pressure stabilization in the buffer chamber 27 is ejected from the air jet holes 25 evenly opened on the middle partition 24, and the household appliances on the conveyor belt 22 of the transmission part are cooled in all directions. This design ensures that the air flow can evenly cover the surface of the product, improves the air cooling efficiency, effectively takes away the heat from the surface of the product, realizes an efficient and orderly cooling process, and ensures that the product can be cooled quickly during transportation.

[0040] Furthermore, when the first conveying roller 20 rotates, the first bevel gear 29 fixedly connected thereto rotates accordingly, and the first bevel gear 29 meshes with the second bevel gear 31, driving the second bevel gear 31 to rotate, thereby causing the reciprocating screw 32 fixedly connected thereto to rotate. The ball nut 33 on the reciprocating screw 32 performs reciprocating linear motion along the reciprocating screw 32 under the action of thread transmission, and the push rod 34 connected to one side of the ball nut 33 pushes the piston 36 to perform reciprocating piston motion in the first water tank 35. The reciprocating motion of the piston 36 causes the coolant to circulate in the liquid cooling system. When the piston 36 moves backward, negative pressure is generated in the first water tank 35, and the coolant in the second water tank 39 is sucked into the first water tank 35 through the pumping pipe 40.

[0041] When the piston 36 moves forward, the coolant in the first water tank 35 is squeezed and transported to the liquid cooling pipe 37 inside the upper groove through the liquid cooling pipe 37. The liquid cooling pipe 37 absorbs the coldness of the coolant and its temperature drops, performing secondary cooling on the air-cooled airflow passing through it. The coolant heated by heat exchange flows out from the other end of the liquid cooling pipe 37, enters the cooler 38 for cooling, and then flows back to the second water tank 39 through the connecting pipe 41, completing the circulation of the coolant. The air-cooled airflow is cooled secondary after passing through the cooled liquid cooling pipe 37, and then cools the product in all directions through the ventilation mesh on the conveyor belt 22.

[0042] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
