Description

Technical Field

[0001] The present invention belongs to the technical field of LED strip welding, and specifically, relates to an LED strip welding device. Background Art

[0002] In the LED strip welding process, generally, a lifting mechanism drives a soldering iron (with a temperature in the range of 250°C to 300°C) to press down, and the solder wire sent by an electric wire feeding mechanism (45) reaches the docking position between the LED strip and the connecting wire, melts the solder wire and evenly coats it at the docking position, thereby completing the welding process. The LED strip is formed by connecting multiple LED lamp beads in series through a flexible circuit board, and has the characteristics of high flexibility and convenient installation. However, when welding with the connecting wire, although the LED strip maintains its flexible plate shape, the connecting wires to be welded are all independent individuals, and this characteristic makes the steps of placing and positioning before welding particularly cumbersome.

[0003] Especially in the welding process of LED strips for low-voltage applications, the connecting wires used are mostly short wires, which are numerous and easy to scatter. To ensure the smooth progress of welding, operators need to accurately place multiple short wires into the preset slots in sequence. This process not only takes time and effort but also increases the operation difficulty. In response to this problem, there are currently two main coping methods in the industry: One is manual operation, that is, the operator holds the LED strip and the short wire in both hands for manual docking. Although this method simplifies the short wire feeding step to a certain extent, in order to save docking time, the operator often needs to hold a handful of short wires to dock with the LED strip, which undoubtedly limits the flexibility of the palm and increases the risk that the connecting wire is not firmly fixed during the welding process, resulting in uneven stress on the welding point and easy loosening, affecting the welding quality.

[0004] The other method is to use an automated welding production line, and the robotic arm clamps the short wire and directly docks it with the LED strip. Although this method has significantly improved the docking accuracy, the robotic arm needs to move frequently between the short wire storage area and the welding area, increasing the production cycle and reducing the welding efficiency of the LED strip. In addition, no matter which short wire feeding and docking method is adopted, it is necessary to strip off a part of the rubber skin at one end of the short wire in advance to expose the internal wire core, and this preparation work also takes a long time, further reducing the welding efficiency of the LED strip. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an LED strip welding device.

[0006] To achieve the aforementioned invention purpose, the technical solutions adopted by the present invention include: A welding table, the top of which is provided with an automatic soldering machine for welding LED light strips; A conveyor belt, wherein the conveyor belt has a conveyor toothed belt for conveying a connecting line, the conveyor toothed belt is provided with a plurality of positioning grooves for inserting the connecting line along the circumference direction, the conveyor toothed belt has an inclined line-complementing segment, the welding table has an inclined surface for conveying the connecting line, the inclined surface has the same slope as the line-complementing segment, the line-complementing segment contacts the connecting line on the inclined surface, and when the conveyor toothed belt is driven, the line-complementing segment slides and rubs against the connecting line, so that the connecting line can be inserted into the positioning groove; In the present invention, the area where the conveyor toothed belt is close to the top of the welding table is the docking section, and the area arranged obliquely below the docking section is the supplementary line section. When the supplementary line section of the conveyor toothed belt rotates to the area close to the top of the welding table, it is transformed into the docking section. Although the areas where the docking section and the supplementary line section are located are fixed, any part of the conveyor toothed belt can enter the docking section or the supplementary line section.

[0007] In the present invention, a plurality of positioning grooves are spaced apart from each other, and the distance is the same as the distance between two adjacent welding points of the LED light strip, so that the connecting wire can be butted against the welding points of the LED light strip only by moving the conveyor belt.

[0008] In the present invention, the connecting wire is a short wire, and the roughness of the inclined surface is 1.6 microns. When the conveyor belt moves, the sliding friction between the conveyor belt and the connecting wire can push the connecting wire into the positioning groove. The conveyor belt and the inclined surface are squeezed relative to each other, so that the connecting wire can be firmly inserted into the positioning groove. Compared with the prior art, the inclination of the inclined surface can be utilized to make the connecting wire slide on it, and the conveyor belt is moved and the connecting wires are respectively inserted into the positioning grooves at corresponding positions. There is no need to manually or use a robot to take the connecting wire. The connecting wire can be automatically inserted into the positioning groove and sent to the area where the LED light strip is welded, eliminating the steps of connecting and installing butt joints. The positioning of the positioning groove avoids uneven force on the welding points, thereby improving the welding efficiency of the LED light strip while also improving the welding quality of the LED light strip.

[0009] A wire feeding mechanism is provided, wherein the wire feeding mechanism can feed the connecting wire to the inclined surface, and a wire feeding channel is provided between the wire feeding mechanism and the conveyor belt so that a plurality of connecting wires are arranged in sequence and pass through the wire feeding channel one by one.

[0010] Preferably, the wire feeding mechanism includes a wire storage plate frame for accommodating connecting wires and a wire feeding plate frame for feeding wires. The wire storage plate frame is internally connected to the wire feeding plate frame. The wire feeding plate frame is internally connected to a wire feeding belt. When the wire feeding belt is driven, the wire feeding belt slides and rubs the connecting wires so that multiple connecting wires are arranged in sequence and the connecting wires are fed into the wire feeding channel one by one.

[0011] In the present invention, the connecting wires can be pushed into the wire feeding channel in sequence by the movement of the wire feeding belt, and the conveying speed of the connecting wires to the wire feeding channel can be controlled by adjusting the moving speed of the wire feeding belt, thereby avoiding the accumulation of connecting wires caused by excessive wire feeding speed per unit time, which is helpful for the welding of LED light strips.

[0012] Preferably, two wire stripping blades are connected to the wire feeding plate frame, a gap is left between the two wire stripping blades for the connecting wires to pass through one by one, a discharge port is opened on one side of the wire feeding plate frame, and one end of the two wire stripping blades is close to the discharge port.

[0013] Preferably, the two stripping blades each have a stripping segment parallel to the moving path of the connecting wire, and one end of the two stripping segments is integrally formed with a wire pushing segment for pushing the rubber toward the discharge port.

[0014] In the present invention, when the connecting wire is pushed to move by the wire feeding belt, the connecting wire will roll in the gap between the two wire stripping blades. The rubber of the connecting wire will be cut by the two wire stripping blades while rolling, and the cut rubber will move to the outside of the discharge port along the guide of the wire stripping section and fall off. Therefore, during the transportation of the connecting wire, the rubber of the connecting wire can be peeled off to expose the wire core. Compared with the prior art, there is no need to peel off the rubber of the connecting wire before feeding, and the wire stripping operation can be performed simultaneously during the feeding process, which further reduces the time consumed by the preparation work before welding the LED light strip and improves the welding efficiency of the LED light strip.

[0015] Preferably, a guide plate is connected to the welding table, and the guide plate includes a cone bar connected to one side of the conveyor belt, and a lifting surface for lifting the connecting line is provided on the top of the cone bar.

[0016] In the present invention, after the LED light strip and the connecting wire are welded, the connecting wire and the LED light strip connected in sequence will be moved by the positioning groove. During the movement, the connecting wire will be gradually pushed out from the positioning groove as the inclination of the top surface of the cone bar changes, until the connecting wire is completely detached from the positioning groove. Compared with the prior art, the LED light strip after welding can be automatically taken out through the cooperation of the conveying toothed belt and the guide plate, which is convenient for collecting the welded LED light strip.

[0017] Preferably, the welding table has a storage space for storing the LED light strip, and the guide plate has a guide surface, and the guide surface is used to guide the LED light strip into the storage space.

[0018] In the present invention, the guiding surface has a slope inclined towards the receiving space. After the welding of the LED light strip is completed, the LED light strip will move onto the guiding surface under the traction of the connecting wire. After the connecting wire completely disengages from the inside of the positioning groove, since the LED light strips have not been split one by one, multiple LED light strips are adhered together in a plate shape and have a larger volume than the connecting wire. Due to gravity, the welded LED light strip will slide in the direction guided by the guiding surface and fall into the receiving space for collection. Compared with the prior art, it can automatically collect the welded LED light strips, facilitating the reprocessing of the LED light strips after welding.

[0019] Preferably, a large gear roller and a small gear roller are rotatably arranged above the inclined surface. The diameter of the large gear roller is larger than that of the small gear roller, and both the large gear roller and the small gear roller are meshed and connected with the conveying toothed belt.

[0020] Preferably, a support plate frame is fixedly connected to one side of the welding table, and the conveying toothed belt is slidably connected to the support plate frame.

[0021] Preferably, the automatic soldering machine includes a bracket fixedly connected to the top of the welding table. A lifting mechanism is arranged inside the bracket, an electric soldering iron is connected to the lifting mechanism, and an electric wire feeding mechanism for feeding solder wire to the electric soldering iron is arranged on one side of the electric soldering iron.

[0022] Compared with the prior art, the advantages of the present invention include: (1) For an LED light strip welding device provided by the present invention, the inclination of the inclined surface enables the connecting wire to slide thereon. It moves through the conveying toothed belt and respectively clamps the connecting wire into the positioning grooves at corresponding positions. There is no need to manually or use a manipulator to pick up the connecting wire, and it can automatically clamp the connecting wire into the positioning grooves and send it to the area where the LED light strip is welded. The steps of connection installation and docking are eliminated, and due to the positioning of the positioning grooves, the situation of uneven stress on the welding points is avoided. While improving the welding efficiency of the LED light strip, the welding quality of the LED light strip is also improved; (2) For an LED light strip welding device provided by the present invention, there is no need to peel the rubber skin of the connecting wire before feeding, and the wire stripping operation can be carried out synchronously during the feeding process, further reducing the time consumed for the preparatory work before welding the LED light strip and improving the welding efficiency of the LED light strip; (3) For an LED light strip welding device provided by the present invention, it can push the connecting wire to move into the wire feeding channel in sequence, and by adjusting the moving speed of the wire feeding belt, the conveying speed of the connecting wire to the wire feeding channel can be controlled, thus avoiding the situation of wire accumulation caused by too fast wire feeding speed per unit time, which is helpful for the welding of the LED light strip; (4) The LED strip welding device provided by the present invention can automatically take out the welded LED strip through the cooperation of the conveying toothed belt and the guide plate, which is convenient for collecting the welded LED strip. (5) For the LED strip welding device provided by the present invention, the welded LED strip will move to the guide surface under the traction of the connecting wire. After the connecting wire completely detaches from the positioning groove, since the LED strips are not split one by one yet, multiple LED strips are stuck together in a plate shape and have a larger volume than the connecting wire. Due to the gravity, the welded LED strip will slide into the storage space in the direction guided by the guide surface for collection. Compared with the prior art, it can automatically collect the welded LED strip, which is convenient for the reprocessing of the welded LED strip. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Please refer to Figure 1 、 Figure 2 and Figure 3 , this embodiment discloses an LED strip welding device, including a welding machine tool 1.

[0034] Specifically, the welding machine tool 1 includes a welding table 11. One side of the welding table 11 is fixedly connected with a feeding table 13. The top of the feeding table 13 has an inclined surface 14 arranged obliquely, and the inclined surface 14 is used for conveying connecting wires. A storage space is opened in the welding table 11, and a storage box 12 is placed in the storage space.

[0035] In this embodiment, an automatic soldering machine 4 is fixedly connected to the soldering table 11. The automatic soldering machine 4 has the same structure as that in the prior art, and all have a lifting mechanism, a soldering iron 44 that moves vertically driven by the lifting mechanism, and an electric wire feeding mechanism 45 for feeding solder wire to the soldering iron 44.

[0036] Specifically, a bracket 41 is fixedly connected to the top of the soldering table 11. The lifting mechanism includes a lifting frame 42 slidably connected in the bracket 41. Two electric telescopic rods 43 are fixedly connected in the bracket 41. The telescopic ends of the electric telescopic rods 43 are fixedly connected to the lifting frame 42. The soldering iron 44 is fixedly connected to the lifting frame 42. The structure of the electric wire feeding mechanism 45 is the same as that in the prior art, and all include an electrical interface, a driving motor, a signal interface, a pressure handle, a wire feeding guide rod, a pressing wheel, a driving wire feeding wheel, and a wire outlet guide rod.

[0037] In this embodiment, the soldering working steps are as follows: Connect the power supply, set the wire feeding speed to 1.5 meters per minute, and the wire feeding direction to forward. Lead out the solder wire from the solder wire reel, pass it through the wire feeding guide rod of the wire feeding mechanism, place it between the wire feeding wheel and the pressing wheel, then pass it through the wire outlet guide rod, and guide it to the soldering iron 44; Start the wire feeding motor, and the welding wire begins to be drawn to the soldering iron 44. According to the soldering parameters, the control system automatically adjusts the wire feeding speed and direction. The welding wire passes through the wire outlet guide rod, is guided to the soldering iron 44, and then the telescopic end of the electric telescopic rod 43 drives the lifting frame 42 to move downward. The soldering iron 44 presses down the solder wire and moves to the connection part between the LED light strip and the connecting wire for soldering.

[0038] Please refer to Figure 1 and Figure 3 , this embodiment discloses an LED light strip soldering device, including a conveyor belt 2.

[0039] Specifically, the conveyor belt 2 includes a large gear roller 23, a small gear roller 24, and a conveying tooth belt 21. Rotating shafts 26 are fixedly connected inside both the large gear roller 23 and the small gear roller 24. The rotating shafts 26 are rotatably connected to the soldering table 11. A conveying motor is fixedly connected inside the soldering table 11. The driving end of the conveying motor is fixedly connected to one of the rotating shafts 26. Both the large gear roller 23 and the small gear roller 24 are meshed with the conveying tooth belt 21. The diameter of the large gear roller 23 is larger than that of the small gear roller 24.

[0040] When in use, starting the conveying motor can drive one of the rotating shafts 26 to rotate. By using the meshing connection between the large gear roller 23, the small gear roller 24 and the conveying tooth belt 21, the conveying tooth belt 21 can be driven to move.

[0041] Further, a plurality of positioning grooves 22 are provided along the circumferential direction of the conveying toothed belt 21, and there is a distance between the plurality of positioning grooves 22, and this distance is the same as the distance between two adjacent welding points of the LED light strip, so that only by moving the conveying toothed belt 21, the connection line can be docked with the welding points of the LED light strip. The top area of the large gear roller 23 and the small gear roller 24 is the docking section of the conveying toothed belt 21, and the docking section is arranged parallel to the horizontal plane. The bottom area of the large gear roller 23 and the small gear roller 24 is the supplementary line segment of the conveying toothed belt 21, and the supplementary line segment is inclined and has the same slope as the inclined surface 14.

[0042] In this embodiment, a support plate frame 25 is fixedly connected to one side of the welding table 11. The support plate frame 25 is slidably connected to the docking section and the supplementary line segment respectively. Through the setting of the support plate frame 25, when the conveying toothed belt 21 moves, it can provide support for the docking section and the supplementary line segment, facilitate the filling of the connection line into the positioning groove 22 of the supplementary line segment, and at the same time, it can also provide a supporting force for the conveying toothed belt 21 in the docking section during soldering, which is helpful for the soldering of the LED light strip.

[0043] Specifically, a partition plate is fixedly connected to the highest point of the inclination of the inclined surface 14. A wire feeding channel 27 is formed between the partition plate and the inclined surface 14. Multiple connection lines are arranged in sequence on the inclined surface 14, and the connection lines enter the wire feeding channel 27 one by one due to their own weight.

[0044] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , an LED light strip welding device, including a guide plate 3.

[0045] Specifically, the guide plate 3 includes a tapered strip 31 fixedly connected to the top of the welding table 11. The tapered strip 31 fits against one side of the conveying toothed belt 21. A jacking surface for jacking up the connection line is provided at the top of the tapered strip 31. The guide plate 3 further includes a guiding surface 33 and a guiding surface 34. The guiding surface 33 can take over the connection line jacked up by the jacking surface, and a chamfer 32 is provided on the side of the guiding surface 33 that first contacts the connection line. The guiding surface 33 can guide the connection line and the LED light strip to move in the position of the guiding surface 34. The connection line connected to the LED light strip is pulled by the weight of the LED light strip and slides down from the guiding surface 34 into the storage box 12 for collection.

[0046] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 8 , an LED light strip welding device, including a wire feeding mechanism 5.

[0047] Specifically, the wire feeding mechanism 5 includes a wire feeding plate frame 52 fixedly connected to the inclined surface 14. A wire feeding channel 27 is arranged between the wire feeding plate frame 52 and the conveyor belt 2. The wire feeding plate frame 52 includes a wire storage plate frame 51 integrally formed therewith. A plurality of connecting wires can be stored in the wire storage plate frame 51. Two wire stripping blades 57 are connected in the wire feeding plate frame 52. A gap for the connecting wires to pass through one by one is left between the two wire stripping blades 57. An outlet 53 is formed on one side of the wire feeding plate frame 52. One ends of the two wire stripping blades 57 are close to the outlet 53.

[0048] In this embodiment, the internal space of the wire feeding plate frame 52 is divided into a wire feeding area 59 and a wire stripping area 510 by taking the two wire stripping blades 57 as the boundary. The wire stripping blades 57 have integrally formed wire stripping segments 571 and pushing segments 572. The wire stripping segments 571 are parallel to the moving path of the connecting wire, and the moving path of the connecting wire is specifically the moving path of the connecting wire in the wire feeding plate frame 52. Among them, the pushing segments 572 are arranged obliquely to the inner wall of the wire feeding plate frame 52, and the inclined direction faces the outlet 53.

[0049] Specifically, two synchronous gear rollers 55 are rotatably connected in the wire feeding plate frame 52. A wire feeding belt 56 is arranged on the two synchronous gear rollers 55. The two synchronous gear rollers 55 are both meshed and connected with the wire feeding belt 56. A wire feeding motor 54 is fixedly connected to one side of the wire feeding plate frame 52. The driving end of the wire feeding motor 54 is fixedly connected to one of the synchronous gear rollers 55. A middle support plate 58 is fixedly connected in the wire feeding plate frame 52. The middle support plate 58 is slidably connected with the wire feeding belt 56, so that when the wire feeding belt 56 pushes the connecting wire to move, the middle support plate 58 can provide a middle supporting force for the wire feeding belt 56.

[0050] It should be noted that by starting the wire feeding motor 54, the synchronous gear roller 55 can be driven to move. Through the transmission between the two synchronous gear rollers 55 and the wire feeding belt 56, the wire feeding belt 56 can move and push the connecting wire to move, so as to automatically supplement the connecting wire to the conveyor belt.

[0051] In this embodiment, during the process of the wire feeding belt 56 pushing the connecting wire to move, the connecting wire will roll in the gap between the two wire stripping blades 57. While rolling, the connecting wire will be cut by the two wire stripping blades 57 to cut off the rubber sheath. The cut rubber sheath will move and fall off outside the outlet 53 along the guiding direction of the wire stripping segment 571. Therefore, during the transportation of the connecting wire, the rubber sheath of the connecting wire can be stripped to expose the wire core. Compared with the prior art, there is no need to peel the rubber sheath of the connecting wire before feeding, and the wire stripping operation can be carried out synchronously during the feeding process, further reducing the time consumed in the preparation work before the welding of the LED light strip and improving the welding efficiency of the LED light strip.

[0052] In this embodiment, the welding implementation steps of the LED light strip are as follows: S1. Place the connecting wires with the same length after cutting into the wire storage board frame 51. Starting the feeding motor 54 can drive the synchronous gear roller 55 to move. Through the transmission between the two synchronous gear rollers 55 and the wire feeding belt 56, the wire feeding belt 56 can be driven to move and push the connecting wires to move on the inclined surface 14. During this process, the rubber skins of the connecting wires will be peeled off by the two wire stripping blades 57 to expose the wire cores. Multiple connecting wires are arranged in sequence and pass through the wire feeding channel 27 one by one, automatically supplementing the connecting wires to the conveyor belt 2. S2. Starting the conveyor motor can drive one of the rotating shafts 26 to rotate. By using the meshing connection between the large gear roller 23, the small gear roller 24 and the conveyor belt 21, the conveyor belt 21 can be driven to move. When the conveyor belt 21 moves, by using the sliding friction between the conveyor belt 21 and the connecting wires, the connecting wires can be pushed into the positioning groove 22. By using the relative extrusion between the conveyor belt 21 and the inclined surface 14, the connecting wires can be firmly clamped into the positioning groove 22 and then transported to the position of the automatic soldering machine 4 by the conveyor belt 21. When the connecting wires move to the position where they contact the welding points of the LED light strip, turn off the conveyor motor to stop the movement of the connecting wires. Then, the telescopic end of the electric telescopic rod 43 drives the lifting frame 42 to move downward, and the soldering iron 44 presses down the solder wire and moves to the connection between the LED light strip and the connecting wires for soldering. S3. After the LED light strip and the connecting wires are soldered, the positioning groove 22 will carry the successively connected connecting wires and LED light strip to move. During the movement, the connecting wires will gradually be pushed out of the positioning groove 22 as the inclination of the jacking surface at the top of the tapered bar 31 changes. After the connecting wires are completely separated from the positioning groove 22, since the LED light strips have not been split one by one, multiple LED light strips are stuck together in a plate shape and have a larger volume than the connecting wires. The soldered LED light strips will slide into the storage box 12 in the storage space in the direction guided by the guiding surface 34 due to gravity.

[0053] It should be understood that the above embodiments are only used to illustrate the technical concept and features of the present invention. The purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can be made. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
