Description

Technical Field

[0001] The invention relates to the technical field of light strip welding, and in particular to a LED light strip welding device. Background Art

[0002] LED light strips are LEDs assembled on a strip-shaped FPC (flexible circuit board) or PCB hard board, and are named because of their shape like a strip. They are gradually emerging in various decoration industries because of their long service life (normal life is generally 80,000-100,000 hours), energy saving and green environmental protection. During the production process of LED light strips, the shorter and wider LED light strips produced need to be spliced ​​together through welding devices, and then the spliced ​​LED light strips are divided into longer and narrower LED light strips by cutting to facilitate assembly and sales.

[0003] A Chinese patent document with authorization announcement number CN116984742B discloses an automatic welding device for light strips, which includes a base and two light strip positioning seats that are horizontally slidably connected to opposite ends of the base; a fixed block arranged between the two light strip positioning seats and located above the light strip positioning seats, and a laser welding head is vertically installed on the fixed block; a bracket connected to the fixed block; a motor vertically installed on the bracket, a rotating block is driven and connected to the output shaft of the motor, and a grinding wheel is provided on the bottom surface of the rotating block; a driving mechanism that can synchronously move longitudinally when driving the fixed block to move horizontally, the motor drives the grinding wheel to rotate, and then drives the fixed block to move horizontally through the driving mechanism, so that the grinding wheel can grind and polish the surfaces of the two welding ends of the light strips, remove oxides and foreign matter on the surface of the light strips, and at the same time improve the smoothness of the surface of the welding area of ​​the light strip, which is beneficial to the concentration of laser light from the laser welding head and improves the accuracy and efficiency of laser welding.

[0004] However, the structural design of the above-mentioned related technology: in the process of welding the LED light strips, only two LED light strips can be welded, which is inconvenient to continuously weld the light strips. When the LED light strips need to be spliced ​​together to be longer, other welding equipment is required to weld the two spliced ​​light strips with another two spliced ​​light strips, which makes the welding efficiency of the light strips low, thereby affecting the welding efficiency.

[0005] Therefore, an LED light strip welding device is proposed to solve the above-mentioned problems. Summary of the invention

[0006] The present invention provides an LED light strip welding device, aiming to solve the problem in the related art that it is inconvenient to perform continuous welding on the light strip.

[0007] The LED light strip welding device of the present invention comprises a shell, a placement plate and a telescopic member, wherein the placement plate is mounted on the telescopic member, the telescopic member is arranged on the inner bottom wall of the shell, a mounting ring is arranged above the placement plate, the mounting ring can rotate around itself, a plurality of sliding holes are opened on the inner side of the mounting ring, a movable cylinder is slidably connected inside the sliding hole, a piston is mounted on the movable cylinder, the piston is elastically slidably arranged in the sliding hole along the length direction of the movable cylinder, a suction cup is mounted on one end of the movable cylinder penetrating the mounting ring, and an exhaust valve is arranged on the movable cylinder;

[0008] The inner side of the mounting ring is rotatably connected with an air inlet cylinder to blow air into the sliding hole. A seal is arranged between the mounting ring and the air inlet cylinder. An air supply pipe is arranged on the air inlet cylinder, and an air pump is connected to the air supply pipe.

[0009] A mounting seat is arranged above the mounting ring, an electric slide rail 1 is arranged on the mounting seat, a lifting plate is arranged on the electric slide rail 1, a welding head is arranged on the lifting plate to connect two light strips, and pressure plates are arranged on both sides of the welding head.

[0010] Beneficial effect: the mounting ring drives the suction cup to rotate through the movable cylinder. When the suction cup rotates to the top of the placement plate, the air pump inflates the air into the air inlet cylinder through the air supply pipe. The gas entering the air inlet cylinder enters the sliding hole and pushes the suction cup on the movable cylinder to move through the piston, so that the suction cup contacts the light strip on the placement plate and the light strip is adsorbed on the suction cup. Then, as the fixed plate continues to rotate, the suction cup moves out of the range of the placement plate and drives the adsorbed light strip to move up. At this time, the subsequent suction cup continues to adsorb the light strip on the placement plate. When the ends of the two light strips are both below the welding head, the welding head welds the two light strips to connect the two light strips. When the two light strips are welded, the suction cup continues to rotate to drive the two welded light strips to rotate and transfer the subsequent light strip ends to the bottom of the welding head. At this time, the welded light strip end is welded to the unwelded light strip head end through the welding head to achieve the effect of continuous welding of the light strip.

[0011] Preferably, the bottom of the air intake cylinder has an opening corresponding to the sliding hole, an air intake pipe is installed at one end of the air intake cylinder, the air intake pipe is rotatably connected to the air supply pipe, a receiving groove is opened on the inner wall of the air intake cylinder, a baffle is slidably connected to the inside of the receiving groove, the baffle has a bent portion at one end extending out of the receiving groove, the bent portion of the baffle is sealed with the inner wall of the mounting ring, and a connecting plate is installed on the inner side of the baffle.

[0012] The effect is that, by rotating the baffle, the sliding holes can be blocked to adjust the number of open sliding holes, thereby adjusting the number of contacts between the suction cup and the light strip to absorb light strips of different lengths.

[0013] Preferably, an adjusting component is installed on the connecting plate, and a connecting component is rotatably connected to the adjusting component.

[0014] Preferably, the connecting assembly comprises a connecting cylinder and a limiting cylinder, the connecting cylinder is mounted on one end of the air inlet cylinder, and the limiting cylinder is mounted on one side of the inner wall of the connecting cylinder.

[0016] The effect is that when the limit sleeve completely slides onto the limit shaft, the rotating shaft on the limit shaft is rotated. At this time, the rotating shaft can drive the baffle to extend out of the air intake cylinder through the connecting plate to reduce the opening range of the air intake cylinder, thereby reducing the air supply range, so that the suction cup can be extended one by one or more at the same time. When the baffle is adjusted, the limit sleeve is returned to between the limit cylinder and the limit shaft, and then the limit shaft is rotated in the opposite direction, so that the limit shaft drives the connecting cylinder on the limit cylinder to rotate through the limit sleeve, and the connecting cylinder drives the opening of the air intake cylinder to face directly downward, and the adjustment of the air supply range is completed at this time.

[0017] Preferably, a bidirectional lead screw is rotatably connected to the inner wall of the shell, a sliding rod is installed at the bottom of the other side of the inner wall of the shell, both ends of the bidirectional lead screw are threadedly connected to the outer side with a limiting plate, the limiting plate is slidably connected to the sliding rod, and a plurality of sliding grooves are opened on the limiting plate, and the placement plate can slide up and down along the length direction of the sliding groove.

[0018] The effect is that the two limit plates can be driven to move closer to or farther from each other through the bidirectional lead screw, so that the placement plate can adapt to light strips of different lengths.

[0019] Preferably, a fixing plate and a fixing ring are respectively installed at both ends of the mounting ring, a fixing cylinder is installed at one end of the fixing plate, one end of the fixing cylinder is rotatably connected to a support frame, a control box is installed at the bottom of the support frame, and the air pump is installed on the support frame.

[0020] Preferably, a second electric slide rail is installed on the shell, a mounting arm is slidably connected to the second electric slide rail, and the mounting arm is installed on the mounting seat.

[0021] The effect is that the mounting arm on the second electric slide rail can drive the mounting seat to move up and down, and at the same time the mounting seat can drive the pressing plate to move downward, so that the pressing plate can be pressed on the end of the light strip.

[0022] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: when the mounting ring drives the suction cup to rotate to the top of the placement plate, the air pump inflates the air into the air inlet cylinder through the air supply pipe, and the gas entering the air inlet cylinder pushes the suction cup on the movable cylinder to move through the piston, so that the light strip is adsorbed on the suction cup, and as the fixed plate continues to rotate, the suction cup drives the adsorbed light strip to move upward, and at this time the subsequent suction cup continues to adsorb the light strip on the placement plate, and when the ends of the two light strips are both below the welding head, the welding head welds the two light strips to connect the two light strips, and when the two light strips are welded, the suction cup continues to rotate to drive the two welded light strips to rotate and transfer the subsequent light strip ends to the bottom of the welding head, and at this time the welded light strip end is welded to the unwelded light strip head end through the welding head to achieve the effect of continuous welding of the light strip.

[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0036] like Figure 1 As shown, the material storage mechanism includes a placement component 11, a control box 12 is installed on one side of the placement component 11, a support frame 13 is installed on the top of the control box 12, an air pump 14 is installed on one side of the support frame 13, an air supply pipe 15 is installed at the air outlet end of the air pump 14, the air supply mechanism is rotatably connected to the air supply pipe 15, a locking plate 16 is installed on the outer side of one end of the air supply pipe 15, a motor 17 is installed on one side of the top of the control box 12, a transmission wheel 18 is installed on the driving shaft of the motor 17, and the feeding mechanism is connected to the transmission wheel 18 in transmission.

[0037] like Figure 1 and Figure 2As shown, the placement component 11 includes a shell 111 and a placement plate 115. One side of the shell 111 is installed on the control box 12, and the other side of the shell 111 is provided with a door for opening the shell 111 for replenishing the light strip. The placement plate 115 is located inside the shell 111. The placement plate 115 is in an arc shape. The flexibility of the light strip can be used to form an arc on the placement plate 115. A number of support bars extend outward on both sides of the placement plate 115. A telescopic member 116 is installed at the bottom of the placement plate 115. The telescopic member 116 is installed on the inner bottom wall of the shell 111. In this embodiment, the telescopic member 116 is a hydraulic cylinder. In other embodiments, the telescopic member 116 is a cylinder or an electric telescopic rod. By extending the movable end of the telescopic member 116, the placement plate 115 can be driven to approach the upper feeding mechanism, so that the feeding mechanism can adsorb the light strip at the top of the placement plate 115.

[0038] When loading, first stack the light strips on the placement plate 115 from bottom to top and make the light strips form the same shape as the placement plate 115, then use the loading mechanism to adsorb the top light strip on the placement plate 115. After a light strip is adsorbed, the telescopic part 116 drives the placement plate 115 to move upward so that the top light strip is in the same position.

[0039] like Figure 2 As shown, a bidirectional lead screw 112 is rotatably connected to the bottom of one side of the inner wall of the shell 111, and an adjusting shaft is installed at one end of the bidirectional lead screw 112. The adjusting shaft on the bidirectional lead screw 112 is set on one side of the shell 111, and a sliding rod 117 is installed at the bottom of the other side of the inner wall of the shell 111. The outer sides of both ends of the bidirectional lead screw 112 are threadedly connected to a limiting plate 113, and the limiting plate 113 is slidably connected to the sliding rod 117. A plurality of sliding grooves 114 are opened on the limiting plate 113, and the plurality of sliding grooves 114 are arranged at equal intervals along the width direction of the limiting plate 113, and the support bar on the placement plate 115 is located inside the sliding groove 114.

[0040] Rotating the bidirectional lead screw 112 can drive the two limit plates 113 to move closer to each other to adapt to light strips of different lengths.

[0041] like Figure 1 and Figure 3As shown, the feeding mechanism includes a rotating assembly 31 and a feeding assembly 32. The rotating assembly 31 includes a rotating ring 311. A fixed disk 312 is installed at one end of the rotating ring 311. The fixed disk 312 is provided with a plurality of exhaust holes. A fixed ring 315 is installed at the other end of the rotating ring 311. A through hole is provided at the center of the fixed disk 312. A fixed cylinder 313 is installed at one end of the fixed disk 312. One end of the fixed cylinder 313 is rotatably connected to one side of the support frame 13. The fixed cylinder 313 is coaxially arranged with the fixed disk 312. A transmission wheel 2 314 is installed on the outer side of the fixed cylinder 313. In this embodiment, the transmission wheel 1 18 and the transmission wheel 2 314 are both pulleys. The transmission wheel 1 18 and the transmission wheel 2 314 are connected by belt transmission. In other embodiments, the transmission wheel 1 18 and the transmission wheel 2 314 are both sprockets. The transmission wheel 1 18 and the transmission wheel 2 314 are connected by chain transmission.

[0042] The motor 17 drives the fixed cylinder 313 in the transmission wheel 2 314 to rotate through the transmission wheel 1 18 , and the fixed cylinder 313 can drive the rotating ring 311 to rotate through the fixed plate 312 .

[0043] like Figure 1 and Figure 3 As shown, the feeding assembly 32 includes a mounting ring 321, a piston 323, a movable cylinder 324 and a suction cup 326. The mounting ring 321 is coaxially arranged inside the rotating ring 311, the fixed plate 312 and the fixed ring 315 are respectively installed at both ends of the mounting ring 321, the air supply mechanism is sealed and arranged on the inner side of the mounting ring 321 to supply air to the mounting ring 321, a plurality of sliding holes 322 are opened on the inner wall of the mounting ring 321, and the plurality of sliding holes 322 are distributed in a circular array with the axis of the mounting ring 321 as the center, the movable cylinder 324 is slidably connected inside the sliding hole 322, and the piston 323 is installed at one end of the movable cylinder 324. On the outside, the other end of the movable cylinder 324 is in a closed state, the outer side of the piston 323 is slidably connected to the inner wall of the sliding hole 322 and is sealed by an elastic rubber ring, the other end of the movable cylinder 324 passes through the mounting ring 321 and the rotating ring 311 in sequence and extends to the outside of the rotating ring 311, and the suction cup 326 is installed at the other end of the movable cylinder 324. The suction cup 326 is arc-shaped and is adsorbed by vacuum. In the initial position, the suction cup 326 is attached to the outer side of the rotating ring 311.

[0044] The fixed plate 312 can drive the suction cup 326 on the movable cylinder 324 to rotate through the mounting ring 321. When the suction cup 326 rotates to the top of the placement plate 115, the air supply mechanism blows air into the mounting ring 321. At this time, the gas in the mounting ring 321 pushes the suction cup 326 on the movable cylinder 324 to move through the piston 323, so that the suction cup 326 contacts the light strip on the placement plate 115 and the light strip is adsorbed on the suction cup 326. Then, as the fixed plate 312 continues to rotate, the suction cup 326 moves out of the range of the placement plate 115 and drives the adsorbed light strip to move upward. At this time, the subsequent suction cups 326 continue to adsorb the light strip on the placement plate 115.

[0045] When the ends of the two light strips are both located below the welding mechanism, the welding mechanism welds the two light strips to connect the two light strips.

[0046] like Figure 3 and Figure 4 As shown, an elastic member 325 is installed between the rotating ring 311 and the mounting ring 321. In the present embodiment, the elastic member 325 is a spring. The elastic member 325 is located on the outer side of the movable cylinder 324 to drive the suction cup 326 to reset. An exhaust valve 327 is installed on the outer side of the movable cylinder 324. The exhaust valve 327 is arranged close to the mounting ring 321. The exhaust valve 327 is electrically connected to the control box 12.

[0047] When the two light strips are welded, the rotation of the fixed disk 312 drives the suction cup 326 to rotate, so as to drive the two welded light strips to rotate and transfer the subsequent ends of the light strips to the bottom of the welding mechanism. At this time, the welded light strip end is welded to the unwelded light strip head end through the welding mechanism. As the fixed disk 312 continues to rotate, the suction cup 326 continues to drive the unwelded light strip head end to transfer to the bottom of the welding mechanism to continuously weld the light strip. At the same time, the suction cup 326 in contact with the welded light strip head end stops adsorbing the light strip, so that the welded light strip can droop naturally, so as to facilitate the winding of the welded light strip. When the suction cup 326 stops adsorbing, the exhaust valve 327 on the movable cylinder 324 connected thereto opens to discharge the gas in the slide hole 322. At this time, under the action of the elastic member 1 325, the elastic member 1 325 begins to reset, so as to drive the suction cup 326 to reset.

[0048] like Figure 1 , Figure 3 and Figure 4 As shown, the air supply mechanism includes an air supply component 41, which is arranged on the inner side of the mounting ring 321, and one end of the air supply component 41 is rotatably connected to the air supply pipe 15. One end of the air supply component 41 is provided with a connecting component 42, and an adjusting component 43 is rotatably connected in the connecting component 42. The connecting component 42 can drive the air supply component 41 to rotate in the mounting ring 321, and the adjusting component 43 can adjust the air supply range of the air supply component 41.

[0049] like Figure 1 , Figure 4 and Figure 5 As shown, the air supply assembly 41 includes an air intake cylinder 411, an air intake pipe 414 and a baffle 415. The air intake cylinder 411 is rotatably connected to the inner side of the mounting ring 321, and the mounting ring 321 and the air intake cylinder 411 are sealed by an elastic rubber sleeve. The bottom of the air intake cylinder 411 has an opening corresponding to the slide hole 322. The air intake pipe 414 is installed at one end of the air intake cylinder 411, and one end of the air intake pipe 414 extends out of the mounting ring 321 and is rotatably connected to one end of the air supply pipe 15. The locking plate 16 is arranged on the outer side of one end of the air intake pipe 414, and the air intake pipe 414 can be locked by the locking plate 16 to limit the rotation of the air intake pipe 414.

[0050] A receiving groove 412 is provided on the inner wall of the air intake cylinder 411, and the receiving groove 412 is in an arc shape. The baffle 415 is slidably connected in the receiving groove 412. One end of the baffle 415 extending out of the receiving groove 412 has a bending portion, and the bending portion of the baffle 415 is sealed with the inner wall of the mounting ring 321. A connecting plate 416 is installed on the inner side of the baffle 415, and one end of the connecting plate 416 is fixed to the adjusting component 43. A sliding groove 413 for the connecting plate 416 to rotate is provided on the inner wall of the air intake cylinder 411.

[0051] The air pump 14 inflates the air into the air inlet cylinder 411 through the air inlet pipe 414 on the air supply pipe 15 , and the gas entering the air inlet cylinder 411 enters the sliding hole 322 through the opening on the air inlet cylinder 411 .

[0052] like Figure 1 , Figures 3 to 6 As shown, the connection assembly 42 includes a connection cylinder 421 and a stop cylinder 422. The connection cylinder 421 is installed on the end of the intake cylinder 411 opposite to the intake pipe 414, the connection cylinder 421 penetrates the fixing ring 315 and extends out of the fixing ring 315, and the stop cylinder 422 is installed on one side of the inner wall of the connection cylinder 421. In this embodiment, the stop cylinder 422 is an external spline cylinder.

[0053] like Figure 1 , Figures 4 to 6 As shown, the adjustment component 43 includes a limit shaft 431, a rotating shaft 432, a turntable 433 and a limit sleeve 434. One end of the rotating shaft 432 is installed at one end of the limit shaft 431. In the present embodiment, the limit shaft 431 is an external spline shaft. The other end of the rotating shaft 432 passes through the limit cylinder 422 and the air intake cylinder 411 in sequence and is installed on the connecting plate 416. The turntable 433 is installed at the other end of the limit shaft 431. One end of the turntable 433 is rotatably connected to one end of the connecting cylinder 421. The limit sleeve 434 is slidably connected between the limit cylinder 422 and the limit shaft 431. In the present embodiment, the limit sleeve 434 is an internal spline sleeve.

[0054] When the limiting sleeve 434 completely slides onto the limiting shaft 431 , the limiting shaft 431 can rotate independently. When the limiting sleeve 434 is located between the limiting cylinder 422 and the limiting shaft 431 , the limiting cylinder 422 and the limiting shaft 431 can rotate simultaneously.

[0055] like Figure 6 As shown, a connecting ring 435 is installed on the outer side of one end of the limiting sleeve 434, and two guide rods 436 are installed on one end of the connecting ring 435. One end of the guide rod 436 passes through the turntable 433 and extends to the outside of the turntable 433. A handle 438 is installed on one end of the guide rod 436, and an elastic member 437 is provided on the outer side of the guide rod 436. In this embodiment, the elastic member 437 is a spring, and the elastic member 437 is installed between the turntable 433 and the connecting ring 435 to drive the limiting sleeve 434 to reset.

[0056] When adjusting the air supply range, pulling the handle 438 outward can drive the guide rod 436 to move outward, so that the limit sleeve 434 slides completely onto the limit shaft 431. At this time, the elastic member 437 is stretched, and then the handle 438 is turned. At this time, the handle 438 drives the rotating shaft 432 on the limit shaft 431 to rotate through the turntable 433. The rotating shaft 432 drives the baffle 415 to extend out of the air intake cylinder 411 through the connecting plate 416 to reduce the opening range of the air intake cylinder 411, thereby reducing the air supply range, so that the suction cup 326 can be extended individually or multiple at the same time to adsorb light strips of different lengths.

[0057] When the baffle 415 is adjusted, the handle 438 is released. Under the action of the elastic member 437, the limiting sleeve 434 returns to between the limiting cylinder 422 and the limiting shaft 431, and then the handle 438 is rotated in the opposite direction so that the opening of the air inlet cylinder 411 faces directly downward, and the adjustment of the air supply range is completed.

[0058] like Figure 1 As shown, the welding mechanism includes a mounting base 21, an electric slide rail 22, a lifting plate 23 and two welding heads 24. The electric slide rail 22 is installed on the inner wall of the mounting base 21, the lifting plate 23 is slidably connected to one side of the electric slide rail 22, and the two welding heads 24 are respectively slidably connected to one side of the lifting plate 23. A cylinder (not shown in the figure) is provided inside the lifting plate 23. The cylinder in the lifting plate 23 is connected to the two welding heads 24 to drive the welding heads 24 to move up and down.

[0059] Continue to refer Figure 1 As shown, fixing rods 25 are provided on both sides of the welding head 24, and the two ends of the fixing rod 25 are respectively installed on both sides of the inner wall of the mounting base 21, and a pressing plate 26 is installed at the bottom of the fixing rod 25 to press on the ends of the two light strips.

[0060] like Figure 1 and Figure 2As shown, a mounting arm 27 is installed on one side of the mounting seat 21, and an electric slide rail 28 is slidably connected to one side of the mounting arm 27. The electric slide rail 28 is installed on one side of the shell 111. The mounting seat 21 can be driven to move up and down through the electric slide rail 28 to adjust the initial height of the welding head 24.

[0061] Working principle: During welding, the motor 17 drives the fixed cylinder 313 on the transmission wheel 2 314 to rotate through the transmission wheel 1 18, and the fixed cylinder 313 drives the rotating ring 311 to rotate through the fixed plate 312. At the same time, the fixed plate 312 drives the suction cup 326 on the movable cylinder 324 to rotate through the mounting ring 321.

[0062] When the suction cup 326 rotates to the top of the placement plate 115, the air pump 14 inflates the air into the air inlet cylinder 411 through the air inlet pipe 414 on the air supply pipe 15, and the gas entering the air inlet cylinder 411 pushes the suction cup 326 on the movable cylinder 324 to move through the piston 323, so that the suction cup 326 adsorbs the light strip. Then, as the fixed plate 312 continues to rotate, the suction cup 326 moves out of the range of the placement plate 115 and drives the adsorbed light strip to move upward. At this time, the subsequent suction cups 326 continue to adsorb the light strip on the placement plate 115.

[0063] When the ends of the two light strips are both below the welding head 24, the electric slide rail 28 drives the mounting seat 21 to move downward through the mounting arm 27, so that the pressure plate 26 is pressed on the ends of the two light strips. At this time, the welding head 24 welds the two light strips to enable power transmission between the two light strips.

[0064] When the two light strips are welded, the suction cup 326 is rotated by the rotation of the fixing plate 312 to drive the two welded light strips to rotate and transfer the subsequent ends of the light strips to the bottom of the welding head 24. At this time, the welded end of the light strip is welded to the unwelded head end of the light strip through the welding head 24.

[0065] As the fixed plate 312 continues to rotate, the suction cup 326 continues to drive the unwelded head end of the light strip to move to the bottom of the welding head 24 to achieve the effect of continuous welding of the light strip. At the same time, the suction cup 326 in contact with the head end of the welded light strip stops adsorbing the light strip, so that the welded light strip can naturally droop due to gravity, so as to facilitate the winding of the welded light strip.

[0066] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
