Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a welding device for processing and producing LED filament lamp driver boards. Background Technology

[0002] A welding device for processing LED filament lamp driver boards is mainly used for the precise welding of electronic components on LED filament lamp driver boards. LED filament lamp driver boards typically include various electronic components, such as resistors, capacitors, diodes, and LED chips. These components need to be accurately and stably mounted on the driver board using a welding device. The design of the welding device needs to consider efficiency, accuracy, and operability.

[0003] According to a public announcement (Publication No.: CN118768788B), a welding device for processing and producing LED filament driver boards includes a conveyor belt. The outer surface of the conveyor belt is provided with a main body of the equipment. The main body of the equipment also includes two feeding devices, which are disposed on the front and rear surfaces of the conveyor belt. The feeding devices are used to feed welding rods as needed when the conveyor belt is conveying the LED driver board and subsequent components for welding, so as to ensure that the main body of the equipment can normally weld the LED filament to the LED driver board and ensure the normal operation of the device. A processing device is disposed on the top of the conveyor belt. The processing device is used to cooperate with the conveyor belt to pre-treat the welding surface of the LED driver board.

[0004] The aforementioned method, through the cooperation between components such as the conveyor belt and the main body of the equipment, is insufficient to resolve welding inaccuracies or quality issues caused by changes in the position of the drive board, resulting in reduced welding precision of the drive board, which needs improvement. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a welding device for processing and producing LED filament lamp driver boards, which solves the technical problems of inaccurate welding or quality caused by changes in the position of the driver board in the prior art.

The presence of two clamping plates is beneficial for clamping the two sides of the filament lamp.

[0009] For example, in a welding device for processing and producing LED filament lamp driver boards provided in at least one embodiment of this utility model, the bidirectional lead screw, the limiting rod, and the threaded sleeve are located on the inner wall of the dustproof shell, and the fan blade is located on the top of the welding table. The design of the dustproof shell is beneficial to protecting the bidirectional lead screw, the limiting rod, and the threaded sleeve.

[0010] For example, in a welding device for processing and producing LED filament lamp driver boards provided in at least one embodiment of the present invention, a switch is provided on the side of the motor, and a torsion spring is fixedly connected to the circumferential surface of the rotating shaft. The end of the torsion spring away from the rotating shaft is fixedly connected to the bottom of the L-shaped rod. The design of the torsion spring is beneficial to the automatic reset of the rotating shaft when it is not driven.

[0011] For example, in at least one embodiment of the present invention, a welding device for processing and producing LED filament lamp driver boards is provided, which further includes: the welding head is located at the top of the welding table, and two threaded sleeves are provided, which are symmetrical to each other along the vertical central axis of the bidirectional screw. This design is beneficial to use the welding head to directly weld the filament lamp on the welding table.

[0012] According to another aspect, at least one embodiment of this utility model also provides a welding device for processing and producing LED filament lamp driver boards, comprising: a cleaning component provided on the top of the welding table, the cleaning component including a through-hole groove, the through-hole groove being opened on the top of the welding table, a crossbar fixedly connected to the side of the L-shaped rod, a pressure chamber fixedly connected to one end of the crossbar, a push rod passing through one end of the pressure chamber, a triangular block fixedly connected to one end of the push rod, a second push rod passing through one end of the pressure chamber, a vibrating rod fixedly connected to one end of the second push rod, a thin rod fixedly connected to the top of the clamping plate, a pressing block fixedly connected to one end of the thin rod, the through-hole groove being opened on the welding table, waste generated during welding may fall from the through-hole groove, and the welding table is struck by the vibrating rod to prevent the through-hole groove from becoming clogged.

[0013] For example, in a welding device for processing and producing LED filament lamp driver boards provided in at least one embodiment of this utility model, the triangular block is located on the displacement trajectory of the extrusion block, and the welding table is located on the displacement trajectory of the vibrating rod. This design is beneficial for striking the welding table when the vibrating rod moves.

[0014] For example, in a welding device for processing and producing LED filament lamp driver boards provided in at least one embodiment of the present invention, there are also: a plurality of through-hole slots are provided and arranged in a linear array on the top of the welding table; a spring is fixedly connected to the circumferential surface of the push rod; the end of the spring away from the push rod is fixedly connected to one end of the pressure chamber; the design of the spring facilitates that the push rod can automatically reset when it is not squeezed.

[0015] For example, in a welding device for processing and producing LED filament lamp driver boards provided in at least one embodiment of the present invention, a second spring is fixedly connected to the circumferential surface of the second push rod. The end of the second spring away from the second push rod is fixedly connected to one end of the pressure chamber. The design of the second spring is beneficial to the automatic reset of the second push rod when it is not compressed.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] In this invention, the interoperability of components such as the bidirectional lead screw, motor, clamping plate, and fan blades within the welding anti-displacement heat dissipation assembly enables the drive plate to be clamped by the bidirectional lead screw and two threaded sleeves. This ensures that the drive plate does not move during the welding process, thus avoiding welding inaccuracies or quality problems caused by changes in the position of the drive plate. The synchronous movement of the clamping plate in two directions enhances the stability of the fixation. The rotation of the fan blades generates airflow for cooling, which helps control the temperature rise during the welding process and prevents overheating from damaging the drive plate or welding points, ensuring the safety and reliability of the welding process.

[0018] In this invention, the design of the through-hole groove, achieved through the cooperation of components such as the air pressure chamber, push rod, and vibration rod inside the cleaning assembly, allows impurities to pass through and fall off smoothly, preventing them from remaining on the top of the welding table. This maintains a clean working environment and avoids affecting subsequent welding or other operations. The vibration clears the through-hole groove, preventing blockage caused by impurity accumulation. The vibration cleaning function ensures that the equipment's performance is not affected by impurity accumulation during long-term use, thus maintaining welding accuracy and equipment stability.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0032] like Figures 1-5 As shown, this invention illustrates a welding device for processing and producing LED filament lamp driver boards according to one embodiment of the present invention. The device includes a support leg 1, a welding table 2 fixedly connected to the top of the support leg 1, a welding anti-displacement and heat dissipation assembly 3 on the top of the welding table 2, and a motor 31. The bottom of the motor 31 is fixedly connected to the top of the welding table 2, and a bidirectional lead screw 32 is fixedly connected to the output shaft of the motor 31. A threaded sleeve 33 is threadedly connected to the circumferential surface of the bidirectional lead screw 32. A side of the motor 31 is fixedly connected to... A limiting rod 34 is provided, with one end of the limiting rod 34 away from the motor 31 passing through the side of the threaded sleeve 33. A clamping plate 35 is fixedly connected to the side of the threaded sleeve 33. An L-shaped rod 37 is fixedly connected to the side of the welding table 2. A rotating shaft 38 passes through the top of the L-shaped rod 37. A fan blade 39 is fixedly connected to the circumference of the rotating shaft 38. A diagonal rod 310 is fixedly connected to the circumference of the rotating shaft 38. A pressing rod 312 is fixedly connected to the top of the clamping plate 35. A support rod 313 is fixedly connected to the side of the welding table 2. A welding head 314 is provided at the bottom of the support rod 313.

[0033] In some examples, the inclined bar 310 is located on the displacement trajectory of the extrusion bar 312, and several fan blades 39 are arranged in a circumferential array on the circumferential surface of the rotating shaft 38, which helps to provide stable wind power to blow air onto the welding table 2.

[0034] In some examples, there are two clamping plates 35, which are symmetrical to each other along the vertical central axis of the bidirectional lead screw 32. The top of the welding table 2 is fixedly connected to a dust cover 36 and has two clamping plates 35, which is beneficial for clamping the two sides of the filament lamp driver board.

[0035] In some examples, the bidirectional lead screw 32, the limiting rod 34, and the threaded sleeve 33 are located on the inner wall of the dust cover 36, and the fan blade 39 is located on the top of the welding table 2. The design of the dust cover 36 is beneficial to protecting the bidirectional lead screw 32, the limiting rod 34, and the threaded sleeve 33.

[0036] In some examples, a switch 315 is provided on the side of the motor 31, and a torsion spring 311 is fixedly connected to the circumferential surface of the shaft 38. The end of the torsion spring 311 away from the shaft 38 is fixedly connected to the bottom of the L-shaped rod 37. The design of the torsion spring 311 is conducive to the automatic reset of the shaft 38 when it is not driven.

[0037] In some examples, the welding head 314 is located on top of the welding station 2, and two threaded sleeves 33 are provided and are symmetrical to each other along the vertical central axis of the bidirectional lead screw 32. This design is advantageous for directly welding the filament lamp driver board on the welding station 2 using the welding head 314.

[0038] For example, such as Figures 1-5 As shown, the welding head 314 is driven by a servo motor to weld the filament lamp driver board. The driver board is placed on the welding table 2, with the welding head 314 located at the top of the welding table 2. Two threaded sleeves 33 are provided and are symmetrically arranged along the vertical central axis of the bidirectional lead screw 32. This design facilitates direct welding of the filament lamp driver board on the welding table 2 using the welding head 314. To prevent the driver board from moving during welding, switch 315 is pressed to start the motor 31, which is a three-phase asynchronous motor. The motor 31 rotates forward, which drives the bidirectional lead screw 32 to rotate forward. The bidirectional lead screw 32 then causes the threaded sleeve 33 and clamping plate 35 to move relative to each other, moving them in the same direction. This causes the clamping plate 35 to move closer to the center of the welding table 2. At this time, the drive plate is placed on the welding table 2. When the two clamping plates 35 move relative to each other, they clamp both sides of the drive plate simultaneously, preventing displacement. This relative movement of the clamping plates 35 also drives the pressing rod 312 to move. 310 is located on the movement trajectory of the extrusion rod 312. When the extrusion rod 312 moves, it will extrude against the inclined rod 310, causing the inclined rod 310 to move. The movement of the inclined rod 310 will drive the rotating shaft 38 to rotate. The rotating shaft 38 passes through the top of the L-shaped rod 37 and is rotatably connected to the top of the L-shaped rod 37. When the rotating shaft 38 rotates, it will drive the fan blade 39 to rotate. The rotation of the fan blade 39 will generate a certain amount of wind. The fan blade 39 is located on the top of the welding table 2. When the fan blade 39 rotates, the wind generated will blow directly onto the welding table 2. The drive plate is cooled by airflow to prevent overheating. The drive plate is clamped by a two-way lead screw 32 and two threaded sleeves 33 to ensure that the drive plate does not move during welding, thus avoiding welding inaccuracies or quality problems caused by changes in the position of the drive plate. The synchronous movement of the clamping plate 35 in two directions enhances the stability of the fixation. The fan blade 39 rotates to generate airflow for cooling, which helps to control the temperature rise during welding and avoid overheating that could damage the drive plate or welding point, ensuring the safety and reliability of the welding process.

[0039] like Figures 1-5 As shown, this invention illustrates a welding device for processing and producing LED filament lamp driver boards in another embodiment of the present invention. The device includes: a cleaning component 4 on the top of a welding table 2, the cleaning component 4 including a through-hole groove 41, the through-hole groove 41 being formed on the top of the welding table 2; a crossbar 42 fixedly connected to the side of an L-shaped rod 37, a pressure chamber 43 fixedly connected to one end of the crossbar 42, a push rod 44 penetrating one end of the pressure chamber 43, a triangular block 411 fixedly connected to one end of the push rod 44, a second push rod 45 penetrating one end of the pressure chamber 43, a vibrating rod 46 fixedly connected to one end of the push rod 45; a thin rod 49 fixedly connected to the top of a clamping plate 35, a pressing block 410 fixedly connected to one end of the thin rod 49; and the through-hole groove 41 being formed on the welding table 2. Waste generated during welding may fall from the through-hole groove 41. The vibration rod 46 strikes the welding table 2 to prevent the through-hole groove 41 from becoming clogged.

[0040] In some examples, the triangular block 411 is located on the displacement trajectory of the extrusion block 410, and the welding table 2 is located on the displacement trajectory of the vibrating rod 46. This design is advantageous for striking the welding table 2 when the vibrating rod 46 moves.

[0041] In some examples, several through-hole slots 41 are provided and arranged in a linear array on the top of the welding platform 2. A spring 47 is fixedly connected to the circumferential surface of the push rod 44. The end of the spring 47 away from the push rod 44 is fixedly connected to one end of the pressure chamber 43. The design of the spring 47 is conducive to the automatic reset of the push rod 44 when it is not compressed.

[0042] In some examples, a spring 48 is fixedly connected to the circumferential surface of push rod 45. The end of spring 48 away from push rod 45 is fixedly connected to one end of the pressure chamber 43. The design of spring 48 is to allow push rod 45 to automatically reset when it is not compressed.

[0043] For example, such as Figures 1-5As shown, the clamping plate 35 moves relative to the clamping plate 35, which in turn moves the thin rod 49 and the extrusion block 410. The triangular block 411 is located on the movement trajectory of the extrusion block 410. Both the triangular block 411 and the extrusion block 410 have inclined surfaces. Due to the influence of the inclined surfaces, when the extrusion block 410 presses against the triangular block 411, it will push the triangular block 411 and the push rod 44 into the pressure chamber 43. This causes the push rod 44 to push the gas inside the pressure chamber 43, which in turn pushes the push rod 45 out. The push rod 45 then pushes the vibrating rod 46 out. The welding table 2 is located on the movement trajectory of the vibrating rod 46. When the vibrating rod 46 is pushed out, it will strike the welding table 2 and vibrate it. The through-hole groove 41 is designed to allow fine dust and other particles generated during welding to pass through. Impurities fall through the through-hole groove 41, preventing them from remaining on the top of the welding table 2. When the vibrating rod 46 strikes the welding table 2, it can clear the through-hole groove 41, preventing it from becoming clogged. The striking of the vibrating rod 46 on the welding table 2 can effectively vibrate the surface of the welding table 2, helping to remove dust, welding slag, and other small impurities generated during the welding process. The design of the through-hole groove 41 allows these impurities to pass through smoothly and fall off, preventing them from remaining on the top of the welding table 2, thus maintaining a clean working environment and avoiding affecting subsequent welding or other operations. The clearing effect of vibration on the through-hole groove 41 prevents the through-hole groove 41 from becoming clogged due to the accumulation of impurities. The vibration cleaning function ensures that the equipment will not be affected by the accumulation of impurities during long-term use, thus maintaining welding accuracy and equipment stability.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
