[0014] Compared with the prior art, the present invention has the following beneficial effects: Through the cooperation of the suction component and the electrostatic purifier, the treatment of welding waste gas is realized. During the welding process, the multiple sets of fans in the suction component can extract the waste gas in the protective cavity. The activated carbon adsorber first preliminarily absorbs the organic pollutants and odors in the waste gas, and then transports them to the electrostatic purifier through the vacuum pump. The high-voltage electric field is used to charge the particles in the waste gas and adsorb them on the dust collecting plate, further purifying the waste gas, effectively preventing the waste gas from spreading wantonly, improving the working environment, and protecting the health of the operators. At the same time, an anti-static rubber mat is also laid on the main board to prevent static electricity accumulation, avoid damage to LED lamps and electronic components during welding due to static electricity, ensure stable welding work, and improve product quality.

[0015] Through the cooperation of multiple sets of electric sliders and movable rails, it can move on the main plate, making it convenient to position the circuit board to the welding area. The structure of the first support plate, the first baffle plate and multiple sets of second baffle plates can firmly fix circuit boards of different specifications with the help of positioning bolts and positioning holes to ensure the stability of the circuit board during welding; at the same time, through the cooperation of the push plate, the push rod, the movable rod, the electric cylinder and the limit block, when the welding is completed, the first positioning assembly moves to the mobile platform, and the mobile platform moves outward through the transmission structure. In this process, the first electric cylinder pushes the limit block to move. When the limit block moves to the specified position, due to the setting of its inclined surface, the sliding wheel at one end of the movable rod will move upward along the inclined surface, thereby driving the push plate to overcome the elastic force of the spring and move upward, and smoothly push up the welded circuit board. This makes it unnecessary for operators to manually take the circuit board, which improves the convenience and efficiency of picking up, reduces the manual operation time, and reduces the risk of circuit board damage caused by improper manual operation.

[0016] The partitioning card plate on the partition plate in the second positioning assembly forms a partitioning groove, which can separate and position multiple groups of connecting wires to prevent them from being entangled with each other during the welding process, effectively improving the welding accuracy. The combination of the clamping block, the clamping groove, the clamping plate and the first magnet firmly clamps the connecting wire, ensuring the stability of the connecting wire during welding and guaranteeing the welding quality. When placing the connecting wire, one end of the connecting wire is against the positioning plate to facilitate determining the position of the connecting wire. The clamping plate is then installed to improve the efficiency and accuracy of placing the connecting wire, and effectively reduce welding errors caused by inaccurate positioning; the positioning plate and the moving platform are rotatably connected through a flip spring, which facilitates its reversal in the direction of the welding machine during welding, so that while ensuring the positioning effect, it will not hinder the movement of the second support plate.

[0019] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but cannot be used to limit the scope of protection of the present invention.

[0020] Embodiment 1: Figures 1 to 12As shown, the present invention provides a welding tool for producing LED lamps with a protective structure, including a main body plate 11 and a welding machine 21.

At the same time, a plurality of second slide rails 32 are also arranged on the moving platform 12. One end of the first slide rail 31 and the second slide rail 32 are butted against each other to form a moving slide rail. The first positioning assembly and the second positioning assembly can slide smoothly on the moving slide rail. At the same time, one end of two sets of first slide rails 31 is provided with a protrusion, and the second slide rail 32 is provided with a fixed card slot corresponding to the protrusion. When the first slide rail 31 is butted against the second slide rail 32, the protrusion is stuck in the fixed card slot to form a splicing structure to ensure the stable operation of the moving slide rail. The circuit board 22 is installed inside the first positioning assembly, and the plurality of connecting wires 23 are stuck in the second positioning assembly. A removable protective cover 33 is installed on the main plate 11. The protective cover 33 is connected to the main plate 11 to form a protective cavity. One end of the connecting wire 23 contacts the circuit board 22, and the connection portion between the two is in the protective cavity. The welding machine 21 is fixed on the main plate 11. A through slot is provided on the protective cover 33, so that the welding head at the bottom of the welding machine 21 can pass through the protective cavity and move in the through slot; a sealing cover is provided on the protective cover 33, one end of the sealing cover is connected to the protective cover 33, and the other end is connected to the welding machine 21, so as to form a sealed cavity. The sealing cavity is connected to the protective cavity through the through slot, which strengthens the overall sealing and avoids the leakage of welding exhaust gas. The sealing cover is pleated and made of rubber material. While ensuring the sealing, it will not hinder the use of the welding machine 21. A suction assembly is provided on the protective cover 33, and a gas storage box 34 and an electrostatic purifier 35 are also provided above the main body plate 11. The electrostatic purifier 35 is connected to the gas storage box 34 and the suction assembly respectively. The treated gas enters the gas storage box 34, and the gas storage box 34 can be connected to other equipment; at the same time, during the welding operation, the suction assembly starts to work and extracts the waste gas generated in the protective cavity. The waste gas first passes through the activated carbon adsorber 62 to preliminarily remove organic pollutants and odors therein, and then is transported to the electrostatic purifier 35 through the vacuum pump 65. The activated carbon adsorber 62 can use the HC-500 activated carbon adsorber. In the electrostatic purifier 35, the high-voltage electric field charges the particulate matter in the waste gas, and then adsorbs it onto the dust collecting plate to achieve waste gas purification, effectively prevent the waste gas from spreading randomly in the workshop, improve the working environment, and protect the health of the operators. The electrostatic purifier 35 can use the AAF ES300 electrostatic purifier.In addition, the anti-static rubber pad laid on the surface of the main plate 11 can prevent static electricity accumulation, avoid static electricity from damaging LED lamps and electronic components during the welding process, ensure the stable progress of welding work, and improve product quality; at the same time, its control parts are connected to the external controller, and the operator can adjust the operating status of each component according to the welding process requirements through the controller, and complete operations such as starting, stopping, and speed adjustment.

[0021] like Figures 2 to 4 , Fig.10 As shown, the first positioning assembly includes a first support plate 401, a first baffle plate 402 and a plurality of second baffle plates 403; the first support plate 401 is used as a basic bearing component, and an electric slider is installed at the bottom of the first support plate 401 corresponding to the position of the movable slide rail. The electric slider can slide smoothly on the movable slide rail, so that the first positioning assembly can adjust the position according to the welding requirements. The first baffle plate 402 and the second baffle plate 403 are both fixed on the first support plate 401, and a plurality of positioning through holes 404 are evenly distributed on them. On the first support plate 401, positioning holes 405 are opened at the positions corresponding to these positioning through holes 404. When it is necessary to fix the circuit board 22, the positioning bolt 406 passes through the positioning through holes 404 on the first baffle plate 402 and the second baffle plate 403, and then screws into the positioning hole 405 of the first support plate 401, so as to effectively fix the circuit board 22. The multiple groups of second baffles 403 are parallel to each other and perpendicular to the first baffle 402 . Such a layout enables the circuit board 22 to be stably clamped between the first baffle 402 and the multiple groups of second baffles 403 .

[0022] The first positioning assembly also includes multiple groups of electric suction cups 407. Multiple groups of mounting grooves 408 are pre-opened on the first support plate 401. The electric suction cups 407 are installed in these mounting grooves 408, and their top surfaces are slightly higher than the top surface of the first support plate 401. When the circuit board 22 is placed on the first positioning assembly, it will contact the multiple groups of electric suction cups 407. The adsorption force generated by the electric suction cups 407 can further stabilize the circuit board 22. At the same time, a limited slot 409 is also opened on the first support plate 401, and a push plate 410 is arranged above it. The bottom of the push plate 410 is connected to a push rod 411. The push rod 411 is set in a square shape. The push plate 410 is clamped in the limited slot 409 so that the push plate 410 is parallel to the top surface of the first support plate 401. The push rod 411 passes through the first support plate 401, and a limited plate 412 is arranged at the bottom thereof. A spring is installed between the limited plate 412 and the first support plate 401, and the spring is sleeved on the push rod 411. The push plate 410 contacts the circuit board 22. After the welding is completed, the circuit board 22 can be pushed through a series of linkages. A connection hole is opened at the position corresponding to the push rod 411 of one group of moving platforms 12, and a movable rod 413 is inserted into the connection hole. One end of the movable rod 413 contacts the bottom of the limit plate 412, and the other end is installed with a sliding wheel 414, which contacts the anti-static rubber pad laid on the surface of the main plate 11.

[0023] On the main plate 11, there are provided a mounting slot 14 and a sliding slot 15 which are interlinked with each other. A first electric cylinder 16 is installed above the main plate 11.

An inclined surface is provided on the limit block 17, and the whole is in a trapezoidal shape. When the first positioning assembly moves with the moving platform 12, the sliding wheel 414 will contact the inclined surface of the limit block 17. As the first electric cylinder 16 pushes the limit block 17 to move, the sliding wheel 414 rolls on the inclined surface, thereby driving the movable rod 413 to move upward, and the push plate 410 is pushed by the limit plate 412 and the push rod 411, so that the welded circuit board 22 is smoothly pushed up, which is convenient for the operator to pick up, thereby improving the efficiency and convenience of the welding work.

[0024] like Figure 2 , Figure 5 , Figure 6 , Fig.11As shown, the second positioning assembly includes a second support plate 501 and a partition plate 502. A plurality of electric sliders are installed at the bottom of the second support plate 501. These electric sliders can slide freely on the movable slide rails, so that the second positioning assembly can adjust the position according to the welding requirements. The partition plate 502 is installed above the second support plate 501. A plurality of partitioning cards 503 are distributed on the top surface of the partition plate 502. A partitioning groove 504 is formed between adjacent partitioning cards 503. During the welding operation, a plurality of connecting wires 23 are respectively inserted into these partitioning grooves 504, thereby avoiding the connection wires 23 from being entangled with each other, which provides convenience for the subsequent welding work. On the second support plate 501, a plurality of clamping blocks 505 are arranged, and a clamping groove 506 is opened on each clamping block 505. A clamping plate 507 is placed above the second support plate 501, and the two ends of the clamping plate 507 are respectively inserted into the clamping groove 506. At the same time, a first magnet is also installed in the clamping groove 506, and the first magnet contacts the clamping plate 507. Through the adsorption of the first magnet, the clamping plate 507 can be tightly pressed on the second support plate 501, and the connecting wire 23 is firmly clamped between the clamping plate 507 and the second support plate 501, ensuring that the connecting wire 23 remains stable during the welding process.

[0025] A support frame 508 is installed above the main body plate 11, which is located on one side of the welding machine 21. A plurality of electric lifting rods 509 are arranged on the support frame 508, and a limit box 510 is connected below the support frame 508, and the limit box 510 is connected to the shaft ends of the plurality of electric lifting rods 509. The electric lifting rod 509 can drive the limit box 510 to move up and down. A detachable limit cover plate 511 is installed on the opening surface of the limit box 510, and the limit cover plate 511 can contact the top surface of the clamping plate 507. A second electric cylinder 512 is arranged above the limit box 510, and a second magnet 513 is installed in the limit box 510, and the shaft end of the second electric cylinder 512 passes through the limit box 510 and is connected to the second magnet 513. Through the extension and retraction of the second electric cylinder 512, the adsorption force between the second magnet 513 and the limit cover plate 511 can be controlled, so as to further adjust the clamping degree of the clamping plate 507 on the connecting line 23.

[0026] One group of mobile platforms 12 is provided with a slot corresponding to the second support plate 501, and a positioning plate 514 is arranged above the main body plate 11. The positioning plate 514 is inserted into the slot and is rotatably connected to the mobile platform 12. A flip spring is also installed at the connection so that the positioning plate 514 can be reversed in the direction of the welding machine 21 and automatically restored. The top of the positioning plate 514 and one side of the second support plate 501 are both provided with an arc surface. The existence of the arc surface makes the contact transition between the two natural, reduces collision and jamming, avoids component wear or position offset caused by unsmooth contact, and makes the positioning process smoother and more efficient. A fixed platform 18 is arranged on the main body plate 11, and the top of the fixed platform 18 is inclined, and an electromagnet 515 is installed on the top. When the positioning plate 514 moves to the vicinity of the fixed platform 18, the magnetic force generated by the electromagnet 515 can adsorb the positioning plate 514 on the fixed platform 18, thereby realizing the accurate positioning of the second positioning component and ensuring the smooth progress of the welding work.

Multiple groups of suction pipes 63 are arranged on the top of the protective cover 33. The suction pipes 63 are distributed at the corners of the top of the protective cover 33. One group of suction pipes 63 is located between the multiple groups of suction pipes 63 and are arranged in a staggered manner. Such an arrangement allows the protective cavity to be well connected with the outside through the suction pipes 63.

[0028] A connection box 64 is provided at one end of the suction pipe 63, and the fan 61 is installed in the connection box 64, and the blowing direction of the fan 61 is outward. When the fan 61 is running, a negative pressure will be formed in the protective cavity, and the waste gas generated during the welding process will be extracted through the suction pipe 63.

At the same time, an air pump 65 is also provided on the mounting platform 19, and the air pump 65 is connected to the electrostatic purifier 35 and multiple groups of connection boxes 64 through connecting pipes. An activated carbon adsorber 62 is installed on the connecting pipe between the air pump 65 and the connection box 64. After the waste gas is extracted, it first passes through the activated carbon adsorber 62, which can preliminarily adsorb organic pollutants and odors in the waste gas. Then, the waste gas is transported to the electrostatic purifier 35 by the air pump 65, and further purified in the electrostatic purifier 35. In addition, two groups of exhaust hoods 66 are arranged in the protective cavity, one group of exhaust hoods 66 is connected to one group of suction pipes 63, and the other group is connected to multiple groups of suction pipes 63, and the welding head of the welding machine 21 is just located between the two groups of exhaust hoods 66, so that the waste gas generated during welding can be collected more effectively.

[0029] The main body plate 11 is also provided with a welding platform 67, which is located between the multiple groups of support platforms 13. One end of the circuit board 22 extends out of the first positioning component and is located above the welding platform 67. The welding platform 67 is provided with an assembly slot 68, and a photoelectric sensor 69 is installed in the assembly slot 68. The photoelectric sensor 69 can sense the welding situation.

[0030] Embodiment 2: Based on the welding tool for producing LED lamps with a protective structure provided in Embodiment 1 of the present application, Embodiment 2 of the present application proposes a welding tool for producing LED lamps with a protective structure. Embodiment 2 is only a preferred embodiment of Embodiment 1, and the implementation of Embodiment 2 will not affect the independent implementation of Embodiment 1. Embodiment 2 of the present invention will be further described below.

[0031] like Figure 7 , Figure 8 As shown, one group of mobile platforms 12 is provided with a slot corresponding to the second support plate 501, and a positioning plate 514 is arranged above the main body plate 11. The positioning plate 514 is inserted into the slot and is rotatably connected to the mobile platform 12. A flip spring is also installed at the connection so that the positioning plate 514 can be reversed in the direction of the welding machine 21 and automatically restored. A roller 516 is installed on the top of the positioning plate 514, and a plurality of pulleys 517 are arranged on one side of the second support plate 501. When the positioning plate 514 moves with the mobile platform 12 and approaches the second support plate 501, the roller 516 can contact the bottom surface of the second support plate 501, and the plurality of pulleys 517 can also contact one side of the positioning plate 514. This contact mode makes the relative movement of the positioning plate 514 and the second support plate 501 smoother, reducing friction and wear between components. A fixed platform 18 is arranged on the main body plate 11, and the top of the fixed platform 18 is inclined, and an electromagnet 515 is installed on the top. When the positioning plate 514 moves to the vicinity of the fixing platform 18, the magnetic force generated by the electromagnet 515 can adsorb the positioning plate 514 onto the fixing platform 18, thereby achieving accurate positioning of the second positioning component and ensuring smooth welding work.

[0032] The difference between the second embodiment and the first embodiment is that a roller 516 is installed on the top of the positioning plate 514, and a plurality of pulleys 517 are arranged on one side of the second support plate 501. The roller 516 contacts the bottom surface of the second support plate 501, and the plurality of pulleys 517 contact one side of the positioning plate 514, so that the friction force when the positioning plate 514 and the second support plate 501 move relative to each other can be further reduced, and the wear between the components can be reduced to a greater extent, so that the relative movement of the two is smoother. The remaining conditions are consistent with those of the first embodiment, so this embodiment will not be repeated.

[0033] The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
