Description

Technical Field

[0001] The present invention relates to the technical field of pin welding, and specifically to a pin welding device for LED lamp production. Background Art

[0002] The pins of an LED lamp are conductive components extending from the LED chip package, serving as a bridge connecting the chip to the external circuit. Commonly, there are two pins corresponding to the positive and negative poles respectively. For special-function LED lamps such as RGB tri-color LED lamps, there are three or more pins, and their shapes vary. Straight pins are convenient for inserting into the circuit board sockets for welding, while surface-mount pins are flat and fit on the surface of the circuit board for miniaturized installation. The pin material is mostly copper with good electrical conductivity and thermal conductivity, and some use iron alloys with special treatment and copper or tin plating on the surface to control costs. It not only undertakes the electrical connection function, allowing current to pass through the chip smoothly to make it emit light, but also physically supports and fixes the chip. The pin welding device is a key tool in the electronic manufacturing field for precisely connecting pins with components such as circuit boards.

[0008] The present invention provides a pin welding device for LED lamp production. It has the following beneficial effects:

[0009] 1. For the pin welding device for LED lamp production, there are provided an arc-shaped rubber block 1 and an arc-shaped rubber block 2 to provide a stable and conforming placement and fixing platform for the pins. By utilizing its own elasticity to buffer the pressure when fixing the pins, it prevents the pins from deforming due to excessive extrusion, ensures the integrity of the pins and the accuracy of subsequent welding. After the welding arm accurately moves to the pin welding position, welding operation is performed on the pins to achieve effective connection of the pins. The motor inside the electric fan drives the fan blade to rotate to form suction force, and the toxic gases and welding slag generated during welding are absorbed through the waveform air guide piece, improving the working environment and ensuring the health of the operators. During welding, the double-acting cylinder contracts and the servo motor drives the clamping block to rotate, without affecting the normal rotation of the waveform air guide piece, ensuring the normal absorption of waste gas and welding slag.

[0010] 2. For the pin welding device for LED lamp production, there is provided a moving clamping device. The arc-shaped rubber block 1 and the arc-shaped rubber block 2 provide a stable and conforming placement and fixing platform for the pins. By utilizing its own elasticity to buffer the pressure when fixing the pins, it prevents the pins from deforming due to excessive extrusion, ensures the integrity of the pins and the accuracy of subsequent welding. The linear electric slide rail precisely controls the downward movement of the moving block and the connecting rod, enabling the magnetic block 1 to accurately fit with the magnetic block 2, achieving reliable fixation of the pins. The connecting rod drives the top plate to move, and further enables the welding arm to accurately reach the pin welding position, preparing for welding. The magnetic block 1 and the magnetic block 2 are tightly fitted through magnetic suction force, providing a stable acting force for the arc-shaped rubber block 1 and the arc-shaped rubber block 2 to fix the pins, ensuring the firmness of pin fixation, providing a fastening force for the connection of the slider 1 and the slider 2, and ensuring the stability of the pin translation process. The electric push rod converts the circular motion of the motor into linear motion, driving the push block and the slider 2 to move forward smoothly. The slider 2 is connected to the slider 1 through magnetic suction force, achieving fixed translation of the pins, preventing the welding slag generated during welding from splashing onto other parts such as the moving block, protecting the device from damage, extending the service life of the device, and ensuring the normal operation of the device.

[0011] 3. The pin welding equipment for LED lamp production is provided with an absorption device. After the welding arm accurately moves to the pin welding position, the pin welding operation is carried out to achieve the effective connection of the pins. The motor inside the electric fan drives the fan blade to rotate to form suction force, and the toxic gases and welding slag generated during welding are absorbed through the waveform air guide piece, improving the working environment and ensuring the health of the operators. The special shape of the waveform air guide piece can better guide the air flow, accurately absorb harmful substances, and improve the absorption efficiency. The motor drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate, so that the waveform air guide piece rotates according to the welding position, ensuring that the air flow is accurately guided to the welding place, and more effectively absorbing the toxic gases and welding slag. The activated carbon in the filter layer uses its rich microporous structure to adsorb the toxic and harmful substances and tiny welding slag particles in the gas, purify the gas, and reduce the environmental pollution. The arc-shaped filter piece allows the purified gas to be discharged smoothly, and at the same time prevents external dust and flying debris from entering the electric fan, ensuring the cleanliness and normal operation of the electric fan. The feeding cover and feeding hole facilitate the staff to replace the activated carbon with reduced adsorption capacity in the filter layer, with simple operation, ensuring that the filter layer continuously and effectively plays the filtering role.

[0012] 4. The pin welding equipment for LED lamp production is provided with an adjusting device. During welding, the double-acting cylinder contracts and the servo motor drives the clamping block to rotate, without affecting the normal rotation of the waveform air guide piece, ensuring the normal absorption of waste gas and welding slag. After welding, the servo motor rotates in the reverse direction and the double-acting cylinder expands and contracts, so that the clamping block clamps the waveform air guide piece and translates, driving the surface welding slag to fall off by deformation, realizing the cleaning of the waveform air guide piece and ensuring its subsequent normal operation. The baffle prevents the welding slag splashed during welding from falling on the threaded rod, avoiding damage to the threaded rod and ensuring its normal transmission function. The flow guiding plate guides the air flow again, making the air flow more concentratedly guided to the welding position, and improving the absorption efficiency of waste gas and welding slag.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] The first embodiment, please refer to Figures 1-4 , the present invention is a pin welding device for LED lamp production, including a bottom plate 1, a moving clamping device 2 is fixedly connected to the top of the bottom plate 1, a top plate 3 is fixedly connected to one side of the moving clamping device 2, a welding arm 4 is fixedly connected to the bottom of the top plate 3, an absorption device 5 is fixedly connected to the top of the bottom plate 1, an adjustment device 6 is fixedly connected to the top of the absorption device 5, and one side of the moving clamping device 2 is fixedly connected to one side of the absorption device 5;

[0024] The mobile clamping device 2 includes a connecting rod 21. A moving block 22 is fixedly connected to the bottom of the connecting rod 21. A sliding groove 23 is opened at the bottom of the moving block 22. A first slider 24 is slidably connected to the inner wall of the sliding groove 23. An arc-shaped rubber block 25 is fixedly connected to the inner wall of the first slider 24. A first magnet 26 is fixedly connected to the bottom of the first slider 24. A linear electric slide rail 27 is fixedly connected to one side of the moving block 22. A rectangular plate 28 is fixedly connected to the side of the linear electric slide rail 27 close to the moving block 22. An arc-shaped groove 29 is opened at the top of the rectangular plate 28. A first rectangular groove 210 is opened on the inner wall of the arc-shaped groove 29. An electric push rod 211 is fixedly connected to one side of the inner wall of the first rectangular groove 210. A push block 212 is fixedly connected to the movable end of the electric push rod 211. A second slider 213 is fixedly connected to the top of the push block 212. A second magnet 214 is fixedly connected to the top of the second slider 213. An arc-shaped rubber block 215 is fixedly connected to the inner wall of the second slider 213. The top of the connecting rod 21 is fixedly connected to the bottom of the top plate 3. The bottom of the linear electric slide rail 27 is fixedly connected to the top of the bottom plate 1. One side of the linear electric slide rail 27 is fixedly connected to one side of the absorption device 5. One side of the rectangular plate 28 is fixedly connected to one side of the absorption device 5. The bottom of the rectangular plate 28 is fixedly connected to the top of the bottom plate 1. When in use, the pin is placed in the mobile clamping device 2. After being fixed, it is moved to the welding position. The welding arms 4 weld the pins respectively. The toxic gases and welding slag generated during welding are absorbed, collected and filtered by the absorption device 5 below. The adjusting device 6 guides the airflow generated by the absorption device 5 to make the airflow more accurate for the welding position. The staff places the pin on the arc-shaped rubber block 215. The arc-shaped rubber block 215 has a certain elasticity and softness, which can provide a stable and fitting placement platform for the pin. At this time, the linear electric slide rail 27 is started, and it drives the moving block 22 and the connecting rod 21 connected to the moving block 22 to move downward. A first magnet 26 is installed below the moving block 22, and a second magnet 214 is installed at the corresponding position on the structure where the arc-shaped rubber block 215 is located. When the moving block 22 moves downward to a certain position, the first magnet 26 and the second magnet 214 approach each other. According to the characteristics of the magnet, a strong magnetic attraction force will be generated between the opposite magnetic poles, making the two fit tightly together. At the same time, the arc-shaped rubber block 25 connected to the first magnet 26 also moves downward, cooperating with the arc-shaped rubber block 215 to tightly fix the pin in the middle. Here, the elasticity of the arc-shaped rubber block 25 and the arc-shaped rubber block 215 plays a key role. They can buffer the pressure during the process of fixing the pin, prevent the pin from being deformed due to excessive extrusion, and ensure the integrity of the pin and the accuracy of subsequent welding. While the pin is being fixed, the connecting rod 21 also drives the top plate 3 to move downward. The top plate 3 is connected to the welding arms 4. The downward movement of the top plate 3 enables the welding arms 4 to accurately move to the welding position of the pin, preparing for the subsequent welding work. After the pin is fixed, the electric push rod 211 is started. The working principle of the electric push rod 211 is to drive the screw to rotate through the motor,Convert the circular motion of the motor into the linear motion of the push rod. After the electric push rod 211 is started, it drives the push block 212 to move forward. The push block 212 is connected to the second slider 213. Therefore, the movement of the push block 212 will drive the second slider 213 to move forward together. The second slider 213 and the first slider 24 are fastened together by the magnetic attraction between the first magnetic block 26 and the second magnetic block 214. This magnetic connection method not only ensures the connection stability between the first slider 24 and the second slider 213, but also has a certain degree of flexibility. When the second slider 213 moves forward, due to the magnetic attraction, the first slider 24 will also move forward together, so as to fix and translate the pin, preventing the welding slag generated during welding from splashing onto the moving block 22 or other parts during the welding process, avoiding damage to the equipment and affecting the normal operation and service life of the equipment.

[0025] For the second embodiment, please refer to Figures 1-8 , the present invention provides a pin welding device for LED lamp production: The absorption device 5 includes a collection box 51. The inner wall of the collection box 51 is rotatably connected to a corrugated air guide piece 52 through a rotating bolt. Circular holes 53 are opened on both sides of the collection box 51. A filter layer 54 is fixedly connected to the inner wall of the circular hole 53. An electric fan 55 is fixedly connected to one side of the filter layer 54. An arc-shaped filter piece 56 is fixedly connected to the inner wall of the circular hole 53. A rectangular groove two 57 is opened on one side of the collection box 51. A motor 58 is fixedly connected to one side of the inner wall of the rectangular groove two 57. A driving shaft of the motor 58 is fixedly connected to a driving wheel 59. A driven wheel 510 is engaged with one side of the driving wheel 59 by a gear. A feeding hole 511 is opened on the top of the collection box 51. A feeding cover 512 is rotatably connected to the top inner wall of the feeding hole 511 through a rotating bolt. The bottom of the collection box 51 is fixedly connected to the top of the bottom plate 1. The top of the collection box 51 is fixedly connected to the bottom of the adjusting device 6. One side of the collection box 51 is fixedly connected to one side of the linear electric slide rail 27. One side of the corrugated air guide piece 52 is rotatably connected to one side of the rectangular plate 28 through a rotating bolt. A driving shaft of the motor 58 is fixedly connected to the corrugated air guide piece 52. The bottom of the feeding hole 511 is communicated with the filter layer 54;

[0026] The adjusting device 6 includes a support block 61 and a folding rod 68. One side of the support block 61 is fixedly connected to a servo motor 62. The drive shaft of the servo motor 62 is fixedly connected to a threaded rod 63. One end of the threaded rod 63 penetrates and is threadedly connected to a clamping block 64. A jack 65 is provided on the side of the clamping block 64 close to the support block 61. The top of the support block 61 is fixedly connected to a baffle 66. The bottom of the baffle 66 is fixedly connected to a flow guide plate 67. One side of the folding rod 68 is fixedly connected to a double-acting cylinder 69. The bottom of the support block 61 is fixedly connected to the top of the collection box 51. The bottom of the folding rod 68 is fixedly connected to the top of the collection box 51. The side of the flow guide plate 67 away from the baffle 66 is fixedly connected to one side of the support block 61. When in use, when the pin moves to the appropriate welding position, the welding arm 4 starts to weld the pin. During the welding process, high temperature will be generated, and at the same time, harmful substances such as toxic gases and welding slag will be generated. In order to ensure the safety of the working environment and the health of the operators, and to prevent these harmful substances from damaging the equipment, the electric fan 55 is started. After the electric fan 55 is started, the motor inside it drives the fan blades to rotate at high speed. According to the principle of fluid mechanics, the rotation of the fan blades forms a low-pressure area inside the electric fan 55, thus generating suction. Under the action of the suction, the air flow is absorbed into the electric fan 55 through the corrugated air guide piece 52. The special shape of the corrugated air guide piece 52 can better guide the air flow so that it can accurately absorb the toxic gases and welding slag generated by welding. At the same time, the motor 58 is started. The output shaft of the motor 58 is connected to the driving wheel 59. The motor 58 converts electrical energy into mechanical energy and drives the driving wheel 59 to rotate. The driving wheel 59 is connected to the driven wheel 510 through a transmission device such as a belt or a chain. The rotation of the driving wheel 59 will drive the driven wheel 510 to rotate. The driven wheel 510 is connected to the corrugated air guide piece 52. Therefore, the rotation of the driven wheel 510 will drive the corrugated air guide piece 52 to rotate according to the welding position, which can accurately direct the air flow to the welding area and more effectively absorb the toxic gases and welding slag generated by welding. The absorbed gases and welding slag will first pass through the filter layer 54. Activated carbon is placed inside the interlayer of the filter layer 54. The activated carbon has a rich microporous structure and has a strong adsorption capacity. When the gas passes through the filter layer 54, the activated carbon can adsorb the toxic and harmful substances and tiny welding slag particles in it and filter and purify the gas. The filtered gas is discharged through the arc-shaped filter piece 56. The arc-shaped filter piece 56 can not only allow the purified gas to be discharged smoothly, but also prevent external dust and flying debris from entering the inside of the electric fan 55, ensuring the cleanliness and normal operation of the inside of the electric fan 55. When the adsorption capacity of the activated carbon inside the filter layer 54 decreases after being used for a period of time, it needs to be replaced. At this time, the operator only needs to open the feed cover 512 and put the new activated carbon into the inner interlayer of the filter layer 54 through the feed hole 511 to complete the replacement of the activated carbon. The operation is simple and convenient. During the welding process, the double-acting cylinder 69 is in a retracted state. At the same time, the servo motor 62 is started to drive the threaded rod 63 to rotate.The clamping block 64 is in threaded fit with the threaded rod 63. The rotation of the threaded rod 63 will cause the clamping block 64 to rotate. At this time, the rotation of the clamping block 64 will not affect the normal rotation of the corrugated air guide vane 52, ensuring the normal absorption of waste gas and welding slag during the welding process. When the welding is completed, some welding slag may adhere to the surface of the corrugated air guide vane 52. In order to clean the corrugated air guide vane 52, the servo motor 62 rotates in the reverse direction, so that the groove on the bottom side of the clamping block 64 is clamped with the top of the corrugated air guide vane 52. Then, the double-acting cylinder 69 expands and contracts to both sides, inserts the cylinder into the jack 65, and limits the clamping block 64 to fix it in a specific position. At this time, the servo motor 62 rotates again. Since the clamping block 64 is limited, the clamping block 64 will translate along the threaded rod 63, driving the corrugated air guide vane 52 to deform. The deformation of the corrugated air guide vane 52 will cause the welding slag attached to its surface to be bounced off, thus realizing the cleaning of the corrugated air guide vane 52. In addition, during the entire welding process, the baffle 66 can prevent the splashed welding slag from falling onto the threaded rod 63 during welding, avoiding damage to the threaded rod 63 by the welding slag and affecting its normal transmission function. The deflector 67 guides the air flow again, making the air flow more concentratedly directed to the welding position, improving the absorption efficiency of waste gas and welding slag.,

[0027] When the present invention is in operation, the pins are placed in the moving clamping device 2. After being fixed, they are moved to the welding position. The welding arms 4 weld the pins respectively. The toxic gases and welding slag generated during welding are absorbed, collected and filtered by the absorption device 5 below. The adjusting device 6 guides the airflow generated by the absorption device 5 to make the airflow more accurate to the welding position. The staff places the pins on the arc-shaped rubber block two 215. The arc-shaped rubber block two 215 has a certain elasticity and softness, and can provide a stable and fitting placement platform for the pins. At this time, the linear electric slide rail 27 is started, which drives the moving block 22 and the connecting rod 21 connected to the moving block 22 to move downward. A first magnetic block 26 is installed below the moving block 22, and a second magnetic block 214 is installed at the corresponding position on the structure where the arc-shaped rubber block two 215 is located. When the moving block 22 moves downward to a certain position, the first magnetic block 26 and the second magnetic block 214 approach each other. According to the characteristics of magnets, a strong magnetic attraction force will be generated between opposite magnetic poles, making the two fit tightly together. At the same time, the arc-shaped rubber block one 25 connected to the first magnetic block 26 also moves downward, cooperating with the arc-shaped rubber block two 215 to tightly fix the pins in the middle. Here, the elasticity of the arc-shaped rubber block one 25 and the arc-shaped rubber block two 215 plays a key role. They can buffer the pressure during the process of fixing the pins, prevent the pins from being deformed due to excessive extrusion, and ensure the integrity of the pins and the accuracy of subsequent welding. While the pins are being fixed, the connecting rod 21 also drives the top plate 3 to move downward. The top plate 3 is connected to the welding arm 4. The downward movement of the top plate 3 enables the welding arm 4 to accurately move to the welding position of the pins, preparing for the subsequent welding work. When the pins are fixed, the electric push rod 211 is started. The working principle of the electric push rod 211 is that the motor drives the screw to rotate, converting the circular motion of the motor into the linear motion of the push rod. After the electric push rod 211 is started, it drives the push block 212 to move forward. The push block 212 is connected to the second slider 213, so the movement of the push block 212 will drive the second slider 213 to move forward together. The second slider 213 and the first slider 24 are fastened together by the magnetic attraction between the first magnetic block 26 and the second magnetic block 214. This magnetic attraction connection method not only ensures the connection stability between the first slider 24 and the second slider 213, but also has a certain flexibility. When the second slider 213 moves forward, due to the magnetic attraction, the first slider 24 will also move forward together, thereby fixing and translating the pins, preventing the welding slag generated during welding from splashing onto the moving block 22 or other parts during welding, avoiding damage to the equipment and affecting the normal operation and service life of the equipment. When the pins move to the appropriate welding position, the welding arm 4 starts to weld the pins. During the welding process, high temperature will be generated, and at the same time, harmful substances such as toxic gases and welding slag will be generated. In order to ensure the safety of the working environment and the health of the operators, and to prevent these harmful substances from damaging the equipment, the electric fan 55 is started. After the electric fan 55 is started, the motor inside it drives the fan blades to rotate at high speed. According to the principle of fluid mechanics,The rotation of the fan blades creates a low-pressure area inside the electric fan 55, thereby generating suction. Under the action of the suction, the air flow is absorbed into the electric fan 55 through the corrugated air guide vane 52. The special shape of the corrugated air guide vane 52 can better guide the air flow, enabling it to accurately absorb the toxic gases and welding slag generated during welding. At the same time, the motor 58 starts. The output shaft of the motor 58 is connected to the driving wheel 59. The motor 58 converts electrical energy into mechanical energy and drives the driving wheel 59 to rotate. The driving wheel 59 is connected to the driven wheel 510 through a transmission device such as a belt or a chain. The rotation of the driving wheel 59 will drive the driven wheel 510 to rotate. The driven wheel 510 is connected to the corrugated air guide vane 52. Therefore, the rotation of the driven wheel 510 will drive the corrugated air guide vane 52 to rotate according to the welding position, enabling the air flow to accurately direct to the welding area and more effectively absorb the toxic gases and welding slag generated during welding. The absorbed gases and welding slag will first pass through the filter layer 54. Activated carbon is placed inside the interlayer of the filter layer 54. The activated carbon has a rich microporous structure and has a strong adsorption capacity. When the gas passes through the filter layer 54, the activated carbon can adsorb the toxic and harmful substances and tiny welding slag particles in it, filtering and purifying the gas. The filtered gas is discharged through the arc-shaped filter plate 56. The arc-shaped filter plate 56 can not only allow the purified gas to be discharged smoothly but also prevent external dust and flying debris from entering the inside of the electric fan 55, ensuring the cleanliness and normal operation of the inside of the electric fan 55. When the activated carbon inside the filter layer 54 is used for a period of time, its adsorption capacity will decrease and needs to be replaced. At this time, the staff only needs to open the feed cover 512 and put the new activated carbon into the inner interlayer of the filter layer 54 through the feed hole 511 to complete the replacement of the activated carbon. The operation is simple and convenient. During the welding process, the double-acting cylinder 69 is in a retracted state. At the same time, the servo motor 62 starts and drives the threaded rod 63 to rotate. The clamping block 64 is in threaded cooperation with the threaded rod 63. The rotation of the threaded rod 63 will cause the clamping block 64 to rotate. At this time, the rotation of the clamping block 64 will not affect the normal rotation of the corrugated air guide vane 52, ensuring the normal absorption of waste gas and welding slag during the welding process. When the welding is completed, some welding slag may adhere to the surface of the corrugated air guide vane 52. To clean the corrugated air guide vane 52, the servo motor 62 rotates in the reverse direction, making the groove on the bottom side of the clamping block 64 tightly clamped with the top of the corrugated air guide vane 52. Then, the double-acting cylinder 69 extends and retracts to both sides, inserts the cylinder into the jack 65, and limits the clamping block 64 to fix it in a specific position. At this time, the servo motor 62 rotates again. Since the clamping block 64 is limited, the clamping block 64 will translate along the threaded rod 63, driving the corrugated air guide vane 52 to deform. The deformation of the corrugated air guide vane 52 will cause the welding slag adhering to its surface to be bounced off, thus realizing the cleaning of the corrugated air guide vane 52. In addition, during the entire welding process, the baffle 66 can prevent the splashing welding slag during welding from falling onto the threaded rod 63, avoiding damage to the threaded rod 63 by the welding slag and affecting its normal transmission function. The flow guide plate 67 guides the air flow again.Direct the air flow more concentratedly to the welding position to improve the absorption efficiency of waste gas and welding slag.
