Description

Technical Field

[0001] This utility model relates to the technical field of projection welding, and in particular to an automatic welding device. Background Technology

[0002] Projection welding equipment is a type of welding device mainly used for welding protrusions or holes in various metals. Automatic welding equipment, through the integration of an automated control system and an intelligent sensing module, can automatically complete workpiece identification, positioning, welding parameter adjustment, and welding operations. However, the fumes containing harmful substances generated during the welding process can directly disperse into the indoor air, making it easy for workers to inhale them, which can cause harm to their health over a long period of time. Therefore, an automatic welding device is particularly needed.

[0003] A projection welding device for automotive parts, authorized by announcement number CN221185068U, includes a body and a cleaning component. An upper connecting block and a lower connecting block are fixedly mounted on the body. Both the upper and lower connecting blocks are equipped with positioning blocks, and fasteners are provided within each positioning block. An upper electrode rod and a lower electrode rod are respectively located within each positioning block. The fasteners are used for quick fixing and adjustment of the lower and upper electrode rods. The cleaning component is located on the positioning block connected to the upper electrode rod and is situated outside the upper electrode rod, used to absorb and clean the fumes generated during welding. This invention effectively solves the problems of harmful fumes generated during projection welding, which are easily inhaled by workers and can cause long-term health damage. Furthermore, the removal of the upper and lower electrode rods for cleaning is cumbersome and inconvenient for quick assembly and disassembly. However, the suction port of the smoke-absorbing plate of the aforementioned automotive component projection welding device is located at the bottom, which can only cover the area near the upper electrode rod. The fumes that diffuse from around the lower electrode rod during welding cannot be effectively absorbed, resulting in an incomplete overall purification effect. Furthermore, although the electrode rod can be disassembled for cleaning, the smoke-absorbing components are inconvenient to disassemble and clean, which will affect the smoke-absorbing efficiency over a long period of time.

[0004] To address the aforementioned problems, an automatic welding device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an automatic welding device to solve the problems of existing automatic welding devices mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic welding device, comprising a projection welding machine body, wherein the projection welding machine body comprises an upper electrode rod and a lower electrode rod, and the upper electrode rod and the lower electrode rod are vertically aligned vertically; a fumigation component is provided near the electrode end of the upper electrode rod; two sets of positioning blocks are provided near the electrode end of the upper electrode rod; and an installation component is provided on the outside of the fumigation component.

[0018] 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.

[0019] Example like Figure 1-4As shown, the projection welding machine includes a body 1, which includes an upper electrode rod 2 and a lower electrode rod 3, which are vertically aligned. A fumigation assembly 4 is located near the electrode end of the upper electrode rod 2, and two sets of positioning blocks 5 are located near the electrode end. An installation assembly 6 is located on the outer side of the fumigation assembly 4. The fumigation assembly 4 includes a first smoke collection box 401 installed near the electrode end of the upper electrode rod 2, and a second smoke collection box 402 located at one end of the upper electrode rod 2 near the electrode end. The first smoke collection box 401 and the second smoke collection box 402 form a ring around the surface of the upper electrode rod 2. Multiple sets of smoke inlet holes 403 are evenly distributed at the bottom of the first smoke collection box 401 and the second smoke collection box 402. The bottom wall of each of the cigarette boxes 402 is equipped with a baffle 404. The bottom walls of the first cigarette box 401 and the second cigarette box 402 are equipped with filter elements 405. A slot 406 is provided on one side of the first cigarette box 401, and a block 407 is connected to one side of the second cigarette box 402. The smoking assembly 4 also includes an upper rubber ring 408 installed on the inner top of the first cigarette box 401 and the second cigarette box 402, and a lower rubber ring 409 installed on the inner bottom of the first cigarette box 401 and the second cigarette box 402. The top of the first cigarette box 401 is provided with a connection port 410. The top of the baffle 404 is provided with multiple sets of insertion holes 411. The bottom of the filter element 405 is equipped with multiple sets of insertion blocks 412, and the positions of the insertion blocks 412 and the insertion holes 411 correspond one-to-one.

[0020] It should be noted that in this embodiment, the automatic welding device completes the welding operation based on the projection welding machine body 1, and simultaneously uses the fume extraction component 4 and the installation component 6 to collect the fumes during the welding process and to install and fix the device. The fume extraction component 4 consists of a first fume collection box 401 and a second fume collection box 402. The two are matched and engaged by the slot 406 and the block 407 to form a ring-shaped sleeve on the upper electrode rod 2 and the lower electrode end 3 near the electrode end. During installation, the insert block 412 at the bottom of the filter element 405 is first inserted into the insert hole 411 at the top of the baffle 404. The top edge of the insert block 412 is rounded so that it can easily slide into the insert hole 411 when inserted. The shape of the insert hole 411 is the same as that of the insert block 405. The 12-matching element is slightly larger than the insert block 412, ensuring that the insert block 412 can be inserted smoothly and providing sufficient friction to ensure that the filter element 405 is stable and does not wobble after installation and can be completed manually. The filter element 405 is installed in the space composed of the baffle 404, the first smoke collection box 401 and the second smoke collection box 402 to filter the smoke generated by welding. Then, the locking block 407 of the second smoke collection box 402 is aligned with the locking groove 406 of the first smoke collection box 401 and inserted to make the two splice into a complete ring. In addition, the upper rubber ring 408 on the inner top of the first smoke collection box 401 and the lower rubber ring 409 on the inner bottom of the second smoke collection box 402 are tightly fitted with the upper electrode rod 2 to play a sealing role and prevent smoke from leaking out. The connection port 410 is located on the top of the first smoke collection box 401. External ventilation equipment (such as a fan or vacuum cleaner) is connected through the connection port 410. When the external ventilation equipment is running, a negative pressure environment is formed inside the first smoke collection box 401 and the second smoke collection box 402. The welding fumes enter the smoke collection box through the smoke inlet 403, preventing the fumes from spreading in the workshop and ensuring a safe working environment. The working process of the external ventilation equipment is existing technology and will not be described here. Furthermore, positioning blocks 5 are respectively installed on the upper and lower surfaces of the first smoke collection box 401 and the second smoke collection box 402 to limit the position of the smoke extraction component 4 and prevent the first smoke collection box 401 and the second smoke collection box 402 from sliding along the upper electrode rod 2 and the lower electrode rod 3 when the projection welding machine body 1 is working.

[0021] like Figure 5 As shown, the mounting component 6 includes mounting grooves 601 respectively opened on the outer sides of the first smoke collection box 401 and the second smoke collection box 402. The opening end of the first smoke collection box 401 is provided with four sets of docking cylinders 602, and the opening end of the second smoke collection box 402 is provided with four sets of docking posts 603. The mounting component 6 also includes a first mounting ring 604 installed on the outer side of the mounting groove 601, and a second mounting ring 605 installed on the outer side of the mounting groove 601. The first mounting ring 604 and the second mounting ring 605 form a ring shape and are rotatably connected at one side. A hook 606 is installed on one side of the first mounting ring 604, and a buckle 607 is installed on one side of the second mounting ring 605. The hook 606 and the buckle 607 engage with each other.

[0022] It should be noted that, in this embodiment, the first mounting ring 604 and the second mounting ring 605 in the mounting assembly 6 form a ring and are sleeved in the mounting groove 601 on the outside of the first smoke collection box 401 and the second smoke collection box 402. The two are rotatably connected on one side, and the hook 606 on one side of the first mounting ring 604 and the buckle 607 on one side of the second mounting ring 605 engage with each other to install the smoking assembly 4 on the upper electrode rod 2. At the same time, the docking cylinder 602 at the opening end of the first smoke collection box 401 and the docking post 603 at the opening end of the second smoke collection box 402 correspond one-to-one and engage with each other. The smoking assembly 4 at the lower electrode rod 3 and the mounting assembly 6 are also installed in the same way to ensure that the structure at the upper and lower electrode rods is symmetrical and stable. The docking cylinder 602 is made of POM material. During installation, the operator only needs to align the docking post 603 with the opening of the docking cylinder 602 and apply a thrust to achieve a tight engagement. The entire process does not require misalignment, rotation or complex alignment, and the operator can complete the operation manually.

[0023] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-5When the projection welding machine body 1 is powered on, the upper electrode rod 2 and the lower electrode rod 3 apply pressure to the workpiece and are powered on. The resistance heat generated by the current passing through the workpiece causes the workpiece to melt locally at the welding part, forming a welding point and completing the welding operation. During the welding process, a large amount of smoke and dust will be generated at the welding part (the projection welding machine body 1 is an existing automated equipment, and the specific working principle will not be explained here). Since multiple sets of smoke inlet holes 403 are evenly opened at the bottom of the first smoke collection box 401 and the second smoke collection box 402, the smoke generated by welding enters the smoke collection box through the smoke inlet holes 403 under the action of hot airflow and external suction (matching exhaust equipment). When the smoke enters the smoke collection box, it passes through the filter element 405, which filters the smoke and intercepts solid particles and other impurities. The filtered air is discharged from the external equipment connected to the connection port 410 (if there is a need for subsequent purification, an external purification device can be connected for further processing. This is existing technology and will not be described here). After the filter element 405 has been used for a period of time, its filtration effect will decrease and it needs to be replaced. Loosen the hook 606 of the first mounting ring 604 and the buckle 607 of the second mounting ring 605 to separate the first mounting ring 604 and the second mounting ring 605. At this time, open the first smoke collection box 401 and the second smoke collection box 402, separate the slot 406 and the block 407, take out the old filter element 405, and then insert the new filter element 405 into the insertion hole 411 of the baffle 404 to complete the replacement of the filter element 405.
