[0002] With the continuous development and popularization of LED lighting technology, LED lamps have been widely used in indoor and outdoor lighting, display screens, automotive lighting and other fields due to their advantages of energy saving, environmental protection and long life. However, in the welding process of LED brackets, welding technology has problems such as low efficiency and unstable quality, which makes it difficult to meet the modern LED lighting industry's demand for high precision, high efficiency and high stability. Automated welding processing equipment can realize functions such as automatic feeding, automatic positioning, automatic welding and automatic detection, which greatly improves production efficiency and product quality. At the same time, the application of intelligent technology enables welding processing equipment to be intelligently adjusted and optimized according to production needs, further improving production efficiency and flexibility.

[0003] The Chinese patent with publication number CN 118559316 A and titled “LED bracket welding processing device and method”,

[0004] The invention comprises a workbench, on which a welding assembly, a rotating loading and unloading assembly and a welding auxiliary assembly are installed; the rotating loading and unloading assembly comprises a turntable assembly and a fixed extrusion member; the turntable assembly comprises a rotating disk, on which station slots are provided at equal angles, the station slots located below the welding assembly are welding stations, and a material unloading slot is provided on the workbench; the fixed extrusion member comprises a fixed rod, on the outer side of the fixed rod, extrusion blocks are fixedly installed at equal angles, and the number of extrusion blocks is the same as that of the station slots and the positions correspond one to one; the welding auxiliary assembly comprises a suction cup and a suction cup lifting and driving mechanism, and the suction cup lifting and driving mechanism comprises a pressure block, which is adapted to the extrusion block, and when the extrusion block rotates to the welding station, it presses the pressure block downward, and the pressure block drives the suction cup to move downward, and the suction cup sucks the LED chip after it moves downward into position. The invention improves welding efficiency and welding stability.

[0005] When welding the LED bracket, the prior art of the above patent overcomes the problem that the loading and unloading time is long and the welding efficiency is low when the LED bracket and the LED chip are welded, and the efficiency of the LED bracket is improved by rotating the loading and unloading. However, the above scheme does not mention the technical problem of the transportation of the lamp bead chip during the welding process of the LED bracket.

DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] See also Figure 1-11 An LED bracket welding processing device provided in an embodiment of the present invention includes a bracket 1, a vibration adjustment mechanism 2, a selection mechanism 3, a conveying mechanism 4 and a working mechanism 5. The vibration adjustment mechanism 2 is installed on the right side of the upper end of the bracket 1, the selection mechanism 3 is installed in the middle position of the upper end of the bracket 1, the conveying mechanism 4 is installed on the bracket 1 on the left side below the vibration adjustment mechanism 2, and the working mechanism 5 is installed on the left side of the upper end of the bracket 1. The working mechanism 5 loads the LED lamp bead chip on the LED bracket.

[0037] The vibration adjustment mechanism 2 includes a material collection box 21, a vibration module 22 and a transmission module 23. The material collection box 21 is installed on the bracket 1. The upper end of the material collection box 21 is an opening extending outward. The vibration module 22 is installed in the material collection box 21. The transmission module 23 is installed on the bracket 1 at the lower end of the material collection box 21.

[0038] In the above technical scheme, during operation, the LED lamp bead chip is placed into the vibration adjustment mechanism 2. At this time, the vibration module 22 in the vibration adjustment mechanism 2 vibrates the LED lamp bead chip, so that the LED lamp bead chip is only in a state of facing forward or backward when entering the transmission module 23 (the welding surface of the LED lamp bead chip is the front side), and then the transmission module 23 drives the LED lamp bead chip to move toward the selection mechanism 3. When the LED lamp bead chip moves to the bottom of the selection mechanism 3, the selection mechanism 3 moves downward, and the selection mechanism 3 adjusts the LED lamp bead chip with the reverse side facing downward, so that the front side of the LED lamp bead chip faces downward, and then the selected LED lamp bead chip is sent to the conveying mechanism 4 through the transmission module 23. The conveying mechanism 4 limits the current of the LED lamp bead chip, so that the working mechanism 5 can grab the LED lamp bead chips one by one, and load the grabbed LED lamp bead chips on the LED bracket, and finally the working mechanism 5 welds the LED lamp bead chips on the LED bracket.

[0039] See also Figure 2-3As shown, as the preferred technical solution of this embodiment, the vibration module 22 includes a vibration rod 221, a rotating wheel 222, a vibration frame 223, a vibration tube 224, a limiting frame 225, an airbag 1 226, a vibration motor 227, a cam 228 and an airbag 229. The front and rear sides of the collecting box 21 are provided with limiting grooves, and the vibration rod 221 is slidably arranged in the limiting grooves. The outer side of the vibration rod 221 is provided with a rotating wheel 222, and the inner end of the vibration rod 221 is provided with a vibration frame 223. The vibration frame 223 has a U-shaped structure, and a limiting spring is installed between the vibration frame 223 and the inner wall of the collecting box 21. The vibration frame 223 is evenly provided with discharge grooves, and barrier grooves are provided on both sides of the discharge groove. The airbag 229 is installed in the barrier groove. The vibration tube 224 is evenly installed on the vibration frame 223. The vibration tube 224 has a rectangular hollow structure. The tube 224 corresponds to the position of the discharge trough, and a limit frame 225 is installed on the inner wall of the collection box 21 located on the upper side of the vibration tube 224. The limit frame 225 is evenly provided with screening grooves, and the screening grooves correspond to the positions of the vibration tube 224, and the vibration tube 224 can slide in the screening groove. The limit frame 225 is provided with a mounting groove connected to the screening groove, and an air bag 226 is arranged at the opening in the mounting groove. There are air holes on the limit frame 225 between two adjacent mounting grooves, and the two adjacent mounting grooves are connected through the air holes. A vibration motor 227 is installed on the bracket 1 located on the front and rear sides of the collection box 21 through a motor seat, and a cam 228 is installed on the output shaft of the vibration motor 227. The cam 228 rotates with the rotating wheel 222. An air pipe is arranged on the outside of the collection box 21, one end of the air pipe is connected to the air hole, and the other end of the air pipe is connected to the existing air pump.

[0040] In the above technical scheme, when the LED lamp bead chips are placed on the limit frame 225 in the collection box 21, the air pump works at this time, and the gas is input into the air bag 226 through the cooperation of the air pipe and the air hole. After the air bag 226 expands, the upper end opening of the screening slot is blocked. In this state, the LED lamp bead chips are concentrated on the limit frame 225. When the LED lamp bead chips are vibrated and adjusted, the air pump 2 first works to drive the air bag 229 in the vibration frame 223 to expand, and the air pump 1 works to drive the air bag 226 to reset. At this time, the LED lamp bead chips on the limit frame 225 fall into the vibration tube 224 in an orderly manner under the action of gravity, and then the air pump 1 works to make the air bag 226 block the opening of the screening slot. In this state, the vibration is started. The driving motor 227 controls the rotation of the cam 228, and the cam 228 drives the rotating wheel 222 to vibrate up and down. At this time, the vibration tube 224 on the vibration frame 223 vibrates up and down in the limit frame 225, so that the LED lamp bead chips that fall into the vibration tube 224 are only in a state of facing up or down. During operation, the vibration tube 224 only drives the LED lamp bead chips inside it to vibrate through the temporary blocking of the air bag 229. The friction of a large number of LED lamp bead chips gathered in the vibration adjustment mechanism 2 is reduced by local vibration, avoiding damage to the LED lamp bead chips during vibration. Then the air pump works to drive the air bag 229 to reset, and the transmission module 23 transports the LED lamp bead chips in the vibration tube 224 to the bottom of the selection mechanism 3.

[0042] In the above technical solution, when the conveying roller 232 rotates through the conveying motor 233, the conveying belt 233 then drives the conveying trough to rotate, so that the LED lamp bead chips in the vibration tube 224 fall evenly into the conveying trough, thereby driving the LED lamp bead chips to move toward the empty shell part on the left side of the partition 234.

[0043] Continue reading Figure 4As shown, as a preferred technical solution of this embodiment, the opening and closing unit 235 includes a two-way cylinder 2351, an opening and closing connecting frame 2352 and an opening and closing strip 2353. The opening and closing strip 2353 is evenly arranged in the hollow shell part by a sliding fit.

The two opening and closing strips 2353 are used to control the opening and closing of the through-groove.

[0044] See also Figure 5-Figure 6 As shown, the picking mechanism 3 includes a movable frame 31, a lifting cylinder 32, a movable plate 33, an adjusting cylinder 34, a suction cup 35, a negative pressure pipe 36, and a transmission motor 37.

An adjusting cylinder 34 is installed between the movable plate 33 and the movable frame 31. A suction cup 35 is evenly installed on the lower end surface of the movable plate 33. A negative pressure pipe 36 is rotatably provided on the conveying frame 231 located below the movable frame 31, and the negative pressure pipe 36 rotates with the conveying slot. Adsorption pipes are evenly provided on the negative pressure pipe 36 Hole, the adsorption hole cooperates with the suction cup 35, the rear end of the negative pressure tube 36 is connected to the output shaft of the transmission motor 37 through a coupling, the front end of the negative pressure tube 36 is connected to the existing negative pressure air pump, the transmission motor 37 is installed on the conveying frame 231 through the motor seat, the suction cup 35 is externally connected to the existing air pump, and an adsorption switch is installed in the suction cup 35. A visual sensor is installed on the outer wall on the right side of the collection box 21, and the visual sensor is electrically connected to the adsorption switch in the suction cup 35. When the visual sensor detects that the LED lamp bead chip at the corresponding position is facing up during work, the visual sensor feeds back a signal to the adsorption switch, and the adsorption switch that receives the feedback signal from the visual sensor is opened, and the adsorption switch that does not receive the signal remains in a closed state.

[0045] In the above technical solution, when the LED lamp bead chip enters the empty shell part through the conveyor belt 233, the opening and closing strip 2353 is in a closed state, so that the LED lamp bead chip is attached to the opening and closing strip 2353, and the lifting cylinder 32 drives the movable frame 31 to move downward, and the visual sensor is fed back to the adsorption switch, so that the suction cup 35 on the movable plate 33 sucks out the LED lamp bead chip with the reverse side facing down, and then the lifting cylinder 32 and the adjusting cylinder 34 cooperate to drive the movable plate 33 to move toward the negative pressure tube 36, and the suction cup 35 sucks out the LED lamp bead chip with the reverse side facing down. The chip is put into the adsorption hole, and the negative pressure air pump temporarily adsorbs the LED lamp bead chip through the suction force generated by the suction cup 35, and then the transmission motor 39 drives the negative pressure tube 36 to rotate. At the same time, the negative pressure tube 36 restricts the LED lamp bead chip in the adsorption hole by means of negative pressure. When the negative pressure tube 36 drives the LED lamp bead chip to face down, the negative pressure tube 36 stops adsorption, and the LED lamp bead chip falls into the empty shell. At this time, the two-way cylinder 2351 drives the opening and closing strip 2353 to open through the opening and closing connecting frame 2352, and the LED lamp bead chip falls into the conveying mechanism 4.

A guide frame 45 is installed on the bracket 1 located on the right side of the conveying belt 43, and a guide groove is opened on the upper end surface of the guide frame 45, and the guide groove is Y-shaped.

[0047] In the above technical solution, when the LED lamp bead chip falls onto the conveying belt 2 43, the conveying roller 2 44 drives the belt 2 43 to move toward the working mechanism 5 through the rotation of the conveying motor 2, and the guide frame 45 limits the current of the LED lamp bead chip falling on the belt 2 43. The belt 2 43 gradually becomes narrower through the current limiting of the guide frame 45, so that only one LED lamp bead chip can pass through the narrowest part, and the working mechanism 5 can thus grab the falling LED lamp bead chips one by one.
