Description

Technical Field

[0001] The present invention belongs to the technical field of LED lamp production, and more specifically, relates to a welding tool with a protective structure for LED lamp production. Background Art

[0002] During the production process of LED lamps, soldering operations are often required to solder connecting wires to the LED lamp's circuit board. This ensures a stable power supply to the LED lamp through the connecting wires, ensuring that the lamp can illuminate normally after being connected to the power supply. During the welding process, in order to ensure the quality, stability and reliability of the welding between the LED lamp circuit board and the connecting wires, a welding tool is required. The welding tool can effectively position the circuit board and the connecting wires, avoiding displacement and shaking during the welding process, and ensuring that the solder joints are accurately connected. When soldering LED lamps to the connecting wires, the solder wire used in the welding process contains flux, which produces pungent odors under high temperature. However, traditional welding tooling often only performs a simple welding positioning function and cannot effectively collect, purify and treat the exhaust gas generated during welding, resulting in the uncontrolled spread of exhaust gas, polluting the working environment. At the same time, it may also cause the human body to inhale a certain amount of exhaust gas, which can easily cause physical discomfort to operators after long working hours.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The combination of an exhaust assembly and an electrostatic purifier allows for the treatment of welding exhaust gas. During the welding process, multiple fans in the exhaust assembly draw exhaust gas from the protective chamber. An activated carbon adsorber initially absorbs organic pollutants and odors from the exhaust gas before pumping it to the electrostatic purifier. A high-voltage electric field charges particulate matter in the exhaust gas and attracts it to the dust collector, further purifying the exhaust gas. This effectively prevents the uncontrolled spread of exhaust gas, improves the working environment, and protects the health of operators. Furthermore, an anti-static rubber mat is placed on the main body panel to prevent static electricity from accumulating and damaging LED lamps and electronic components during the welding process, ensuring stable welding and improving product quality.

[0017] 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, ensuring the stability of the circuit board during the welding process; at the same time, through the cooperation of the push plate, push rod, movable rod, electric cylinder and limit block, when the welding is completed, the first positioning assembly moves to the movable table, and the movable table then moves outward through the conveying structure. During 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, pushing up the welded circuit board smoothly. This eliminates the need for operators to manually pick up the circuit board, improving the convenience and efficiency of picking up the parts, reducing manual operation time, and reducing the risk of circuit board damage caused by improper manual operation.

[0018] The dividing card plate on the dividing plate in the second positioning assembly forms a dividing groove, which can separate and position multiple groups of connecting wires to prevent them from getting entangled with each other during welding, effectively improving welding accuracy. The combination of the clamping block, the clamping groove, the clamping plate and the first magnet firmly clamps the connecting wire, ensuring that the connecting wire is stable during welding and guaranteeing 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, effectively reducing welding errors caused by inaccurate positioning; the positioning plate and the movable table are rotatably connected through a flip spring, which facilitates its reversal toward 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.

DETAILED DESCRIPTION

[0033] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but are not intended to limit the scope of protection of the present invention.

[0034] Example 1: Figures 1 to 12As shown, the present invention provides a welding fixture for LED lamp production with a protective structure, comprising a main plate 11 and a welding machine 21. Multiple sets of movable platforms 12 are disposed above the main plate 11. The movable platforms 12 are able to slide freely on the main plate 11 via a conveying structure, which can be a screw drive. The main plate 11 is also provided with multiple sets of support platforms 13, each equipped with a first slide rail 31. Simultaneously, multiple sets of second slide rails 32 are disposed on the movable platform 12. The first and second slide rails 31 and 32 are butted together at one end to form a movable slide rail, upon which the first and second positioning assemblies can slide smoothly. Furthermore, two sets of first slide rails 31 have protrusions at one end, and the second slide rails 32 have corresponding fixing slots. When the first and second slide rails 31 and 32 are butted together, the protrusions engage within the fixing slots, forming a joint structure that ensures stable operation of the movable slide rail. A circuit board 22 is mounted within the first positioning assembly, while multiple sets of connecting wires 23 are positioned within 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 between the two is located in the protective cavity. The welding machine 21 is fixed to 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 within 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, thereby forming a sealed cavity. The sealed cavity is connected to the protective cavity through the through slot, which strengthens the overall sealing and prevents leakage of welding exhaust gas. The sealing cover is pleated and made of rubber material. While ensuring sealing, it will not hinder the use of the welding machine 21. The protective cover 33 is equipped with an exhaust assembly. A gas storage tank 34 and an electrostatic purifier 35 are also located above the main body panel 11. The electrostatic purifier 35 is connected to the gas storage tank 34 and the exhaust assembly, respectively. The treated gas enters the gas storage tank 34, which can be connected to other equipment. Simultaneously, during welding operations, the exhaust assembly activates, extracting the exhaust gas generated within the protective chamber. The exhaust gas first passes through an activated carbon adsorber 62 to initially remove organic pollutants and odors. It is then transported to the electrostatic purifier 35 via an exhaust pump 65. The activated carbon adsorber 62 can be an HC-500 activated carbon adsorber. In the electrostatic purifier 35, a high-voltage electric field charges particulate matter in the exhaust gas, which then attracts it to the dust collector, purifying the exhaust gas. This effectively prevents the exhaust gas from spreading freely within the workshop, improving the working environment and protecting the health of operators. The electrostatic purifier 35 can be an AAF ES300 electrostatic purifier.In addition, the anti-static rubber pad laid on the surface of the main body plate 11 can prevent the accumulation of static electricity, 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 requirements of the welding process through the controller, and complete operations such as starting, stopping, and speed adjustment.

[0035] like Figures 2 to 4 、 Figure 10 As shown, the first positioning assembly includes a first support plate 401, a first baffle 402, and multiple sets of second baffles 403. The first support plate 401 serves as the 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, allowing the first positioning assembly to adjust its position according to welding requirements. The first baffle 402 and the second baffle 403 are both fixed to the first support plate 401, and multiple sets of positioning holes 404 are evenly distributed on them. Positioning holes 405 are opened on the first support plate 401 at the positions corresponding to these positioning holes 404. When the circuit board 22 needs to be fixed, the positioning bolt 406 passes through the positioning holes 404 on the first baffle 402 and the second baffle 403, and then screws into the positioning hole 405 of the first support plate 401, thereby effectively fixing the circuit board 22. The multiple groups of second baffles 403 are parallel to each other and perpendicular to the first baffles 402 . Such a layout enables the circuit board 22 to be stably positioned between the first baffles 402 and the multiple groups of second baffles 403 .

[0036] The first positioning assembly also includes multiple sets of electric suction cups 407. Multiple sets of mounting slots 408 are pre-defined on the first support plate 401. The electric suction cups 407 are mounted within these mounting slots 408, with their top surfaces slightly elevated above the top surface of the first support plate 401. When the circuit board 22 is placed on the first positioning assembly, it comes into contact with the multiple sets of electric suction cups 407. The suction force generated by the electric suction cups 407 further stabilizes the circuit board 22. Furthermore, a limit slot 409 is defined on the first support plate 401, above which is positioned a push plate 410. The push plate 410 is connected to a push rod 411 at its bottom. The push rod 411 is shaped in a square and is positioned within the limit slot 409, ensuring 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 is located at its bottom. A spring is installed between the limit plate 412 and the first support plate 401, and the spring is sleeved around the push rod 411. The push plate 410 contacts the circuit board 22 and, after soldering is complete, pushes the circuit board 22 through a series of linkages. One of the movable platforms 12 has connection holes corresponding to the push rods 411, through which a movable rod 413 passes. One end of the movable rod 413 contacts the bottom of the stop plate 412, while the other end is mounted with a sliding wheel 414, which contacts the antistatic rubber pad on the surface of the main plate 11.

[0037] On the main plate 11, there are provided a mounting slot 14 and a sliding slot 15 that are interconnected. A first electric cylinder 16 is installed above the main plate 11. The first electric cylinder 16 is clamped in the mounting slot 14. A limit block 17 is provided at the end of its shaft, and the limit block 17 is clamped in the sliding slot 15. An inclined surface is provided on the limit block 17, and the whole is trapezoidal in shape. When the first positioning assembly moves with the movable 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 pushing the push plate 410 through 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.

[0038] like Figure 2 、 Figure 5 、 Figure 6 、 Figure 11As shown, the second positioning assembly includes a second support plate 501 and a partition plate 502. Multiple sets 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, allowing the second positioning assembly to adjust its position according to welding requirements. The partition plate 502 is installed above the second support plate 501. Multiple sets of partitioning clips 503 are distributed on the top surface of the partition plate 502, and partition grooves 504 are formed between adjacent partitioning clips 503. During welding, multiple sets of connecting wires 23 are respectively clamped into these partition grooves 504, thereby preventing the connecting wires 23 from being entangled with each other and facilitating subsequent welding work. Multiple sets of clamping blocks 505 are provided on the second support plate 501, each of which is provided with a clamping groove 506. A clamping plate 507 is placed above the second support plate 501, and the two ends of the clamping plate 507 are respectively clamped into the clamping grooves 506. At the same time, a first magnet is installed in the clamping groove 506, and the first magnet contacts the clamping plate 507. Through the adsorption effect of the first magnet, the clamping plate 507 can be tightly pressed against the second support plate 501, firmly clamping the connecting wire 23 between the clamping plate 507 and the second support plate 501, ensuring that the connecting wire 23 remains stable during the welding process.

[0039] A support frame 508 is mounted above the main plate 11 and is located on one side of the welding machine 21. Multiple sets of electric lift rods 509 are mounted on the support frame 508. A limit box 510 is connected below the support frame 508. The limit box 510 is connected to the shaft ends of the multiple sets of electric lift rods 509. The electric lift rods 509 drive the limit box 510 to move up and down. A removable limit cover 511 is mounted on the opening of the limit box 510, which contacts the top surface of the clamping plate 507. A second electric cylinder 512 is mounted above the limit box 510. A second magnet 513 is mounted within the limit box 510. The shaft end of the second electric cylinder 512 extends through the limit box 510 and connects to the second magnet 513. By extending and retracting the second electric cylinder 512, the suction force between the second magnet 513 and the limit cover 511 can be controlled, thereby further adjusting the degree of clamping of the clamping plate 507 on the connecting wire 23.

[0040] One of the movable platforms 12 is provided with a slot corresponding to the second support plate 501. A positioning plate 514 is provided above the main plate 11. The positioning plate 514 is inserted into the slot and is rotatably connected to the movable platform 12. A flip spring is also installed at the connection point 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 presence of the arc surface makes the contact transition between the two natural, reduces collisions and jams, avoids component wear or position offset caused by poor contact, and thus makes the positioning process smoother and more efficient. A fixed platform 18 is provided on the main plate 11. The top of the fixed platform 18 is inclined and an electromagnet 515 is installed on the top. When the positioning plate 514 moves near the fixed platform 18, the magnetic force generated by the electromagnet 515 can adsorb the positioning plate 514 on the fixed platform 18, thereby achieving accurate positioning of the second positioning component and ensuring the smooth progress of the welding work.

[0041] like Figure 2 、 Figure 9 As shown, the suction assembly includes multiple sets of fans 61 and multiple sets of activated carbon adsorbers 62. Multiple sets of suction pipes 63 are installed 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 set of suction pipes 63 is located between the multiple sets of suction pipes 63, and the arrangement is staggered. This arrangement ensures that the protective cavity can be well connected to the outside world through the suction pipes 63.

[0042] Each end of the suction pipe 63 is equipped with a connection box 64. The fan 61 is mounted inside the connection box 64, with the airflow of the fan 61 directed outward. When the fan 61 is running, a negative pressure is created within the protective chamber, drawing the exhaust gases generated during the welding process out through the suction pipe 63. The main body 11 has a mounting platform 19, on which the electrostatic purifier 35 is mounted. An air pump 65 is also mounted on the mounting platform 19, which is connected to the electrostatic purifier 35 and multiple sets of connection boxes 64 via connecting pipes. An activated carbon adsorber 62 is installed on the connecting pipe between the air pump 65 and the connection box 64. After being extracted, the exhaust gas first passes through the activated carbon adsorber 62, which initially absorbs organic pollutants and odors from the exhaust gas. The exhaust gas is then transported by the air pump 65 to the electrostatic purifier 35 for further purification. In addition, two groups of exhaust hoods 66 are set 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. The welding head of the welding machine 21 is located just between the two groups of exhaust hoods 66, which can more effectively collect the waste gas generated during welding.

[0043] The main plate 11 is also provided with a soldering platform 67, which is located between the multiple sets of support platforms 13. One end of the circuit board 22 extends from the first positioning assembly and is located above the soldering platform 67. The soldering platform 67 has an assembly slot 68, within which a photoelectric sensor 69 is mounted. This sensor senses the soldering status and can be an Omron E3Z-D61 photoelectric sensor. A protective plate 36 is installed above the soldering platform 67 and is detachably connected to the soldering platform 67. The circuit board 22 is placed on top of the protective plate 36. The protective plate 36 is made of a transparent material, which protects the photoelectric sensor 69 while not interfering with its operation.

[0044] Example 2: Based on the welding tool for producing LED lamps with a protective structure provided in Example 1 of this application, Example 2 of this application provides a welding tool for producing LED lamps with a protective structure. This Example 2 is merely a preferred embodiment of Example 1, and its implementation does not affect the independent implementation of Example 1. The following further describes Example 2 of the present invention.

[0045] like Figure 7 、 Figure 8 As shown, one of the movable platforms 12 has a slot corresponding to the second support plate 501. A positioning plate 514 is provided above the main plate 11. The positioning plate 514 snaps into the slot and is rotatably connected to the movable platform 12. A flip spring is installed at the connection, allowing the positioning plate 514 to rotate toward the welding machine 21 and automatically return to its original position. A roller 516 is mounted on the top of the positioning plate 514, while multiple sets of pulleys 517 are installed on one side of the second support plate 501. When the positioning plate 514 moves with the movable 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 multiple sets of pulleys 517 can also contact one side of the positioning plate 514. This contact structure allows the positioning plate 514 and the second support plate 501 to move smoothly relative to each other, reducing friction and wear between components. A fixed platform 18 is provided on the main plate 11. The top of the fixed platform 18 is tilted and equipped with an electromagnet 515. 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 progress of the welding work.

[0046] The difference between this second embodiment and the first embodiment lies in the fact that a roller 516 is mounted on the top of the positioning plate 514, and a plurality of pulleys 517 are provided on one side of the second support plate 501. The contact between the rollers 516 and the bottom surface of the second support plate 501, and the contact between the plurality of pulleys 517 and one side of the positioning plate 514, further reduces friction during relative movement between the positioning plate 514 and the second support plate 501, significantly reducing wear between the components and ensuring smoother relative movement. The remaining conditions are consistent with those of the first embodiment and are therefore not further described in this embodiment.

[0047] The basic principles, main features and 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.
