Description

Technical Field

[0001] The utility model relates to an LED lamp string production and processing device, and more specifically, to a truncating and welding device for a novel LED lamp string processing mechanism. Background Art

[0002] Due to its rich colors and low energy consumption, LED lamp strings are widely used in indoor or outdoor decorative structures. The LED lamp string usually includes a leather wire and several lamp beads arranged on the leather wire. Several electric wires are arranged inside the leather wire. The leather wire has good overall insulation and good waterproof and moisture-proof effects, enabling the LED lamp string to be used outdoors. The LED with a leather wire as the lamp string has shown an upward trend in recent years.

[0003] Currently, the processing of the above-mentioned LED lamp strings on the market usually adopts manual assembly line processing, which requires manual wire twisting, soldering, welding, and plastic sealing of the lamp strings. During the production process, multiple workers need to cooperate manually, which not only increases the production cost but also cannot guarantee the production efficiency and product quality. Moreover, the process of wire twisting the lamp strings takes a long time and is difficult to process.

[0004] Currently, in order to ensure the structural strength of the lamp string, the above-mentioned LED lamp string usually twists and connects multiple electric wires. For example, Chinese Patent No. CN110726082A discloses an LED twisted wire lamp string, its production method and production equipment. The LED twisted wire lamp string includes: a first wire, a second wire, and a third wire, which are helically twisted together; several surface-mounted LEDs, and two solder feet of several surface-mounted LEDs are respectively mounted on several first solder joints and several second solder joints. Several surface-mounted LEDs are connected in parallel, series, or in a mixed connection manner; and several encapsulation colloids are respectively coated on the surfaces of several surface-mounted LEDs and the third wire corresponding to the positions of the surface-mounted LEDs. The LED twisted wire lamp string provided by the present invention, due to having three wires, when the LED twisted wire lamp string is a series lamp string, the third wire can increase the strength of the LED lamp string and prevent the surface-mounted LEDs from falling off when pulling the LED twisted wire lamp string; when the LED twisted wire lamp string is a parallel lamp string, the third wire is connected in parallel with the first wire or the second wire, which is beneficial to reducing the voltage attenuation speed and enabling the LED lamp string to be not restricted by the power supply.

[0005] Although the above-mentioned LED lamp string production equipment can realize the automated production of LED lamp strings, during the production process, multiple wires are twisted and wound, and then the wound wires are welded to the corresponding component pins one by one, with low processing efficiency and great processing difficulty. Summary of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a cutting and welding device for a new type of LED lamp string processing mechanism with high automation, convenient production, high processing efficiency, and reliable connection between the lamp string and components.

[0007] To achieve the above object, the present utility model provides the following technical solution: A cutting and welding device for a new type of LED lamp string processing mechanism, including a base, an annular track is provided on the base, several clamping mechanisms are provided on the annular track, the clamping mechanisms slide on the annular track, the annular track includes two relatively arranged vertical tracks and a curved track for connecting the vertical tracks, the clamping mechanism includes a sliding plate slidably connected to the annular track and a clamping jaw provided on the sliding plate, the clamping jaw is used for clamping the LED lamp string, a processing mechanism is provided on the base along the length direction of the vertical track, the processing mechanism includes a cutting component, a tinning component and a welding component, the cutting component includes a cutting knife provided on one side of the annular track and a cutting air cylinder provided on the cutting knife for driving the cutting knife, the tinning component includes a mounting bracket provided on one side of the processing mechanism, a tin storage barrel provided on the mounting bracket and a tinning rod provided in the tin storage barrel, the tin storage barrel is rotatably connected to the mounting bracket, the tinning rod slides on the mounting bracket for adding solder to the cutting place of the LED lamp string, the welding component includes a soldering iron and a soldering plate, the soldering iron is provided at the upper end of the clamping jaw, the soldering plate is provided at the lower end of the clamping jaw, driving members are provided on both the soldering iron and the soldering plate, and the soldering iron and the soldering plate are symmetrically arranged with the clamping jaw as the central axis and can approach or move away from each other through the driving members for welding and forming the LED lamp string and electronic components.

[0008] The present utility model is further arranged as: A transmission belt is further provided in the annular track, connecting plates are provided between the transmission belt and each clamping mechanism, and the transmission belt drives the clamping mechanism to slide on the annular track.

[0009] Preferably, the annular track further includes a transmission wheel drivingly connected to the transmission belt, and the transmission wheel is used for driving the clamping mechanism to intermittently move on the annular track.

[0010] Preferably, when the clamping mechanism runs and stops on the annular track, the cutting knife, the tinning rod, the soldering iron and the soldering plate are all located between adjacent clamping jaws.

[0011] The present utility model is further arranged as that the clamping mechanism further includes an opening and closing member provided at the rear end of the clamping jaw, the opening and closing member includes a pressing plate fixedly connected to the clamping jaw and a return spring provided at the lower end of the pressing plate, and the opening and closing member is configured to allow the clamping jaw to open after being subjected to pressure.

[0012] The present utility model is further configured such that the driving cylinders of the cutting assembly include a feed cylinder and a skin-removing cylinder. The feed cylinder moves in the vertical direction, and the skin-removing cylinder moves in the length direction of the LED light string. Moreover, the moving distance of the feed cylinder = the thickness of the skin wire layer on the upper surface of the LED light string.

[0013] The present utility model is further configured such that the moving range of the soldering rod in the soldering assembly is from the bottom of the solder storage barrel to the bottom of the clamping jaw.

[0014] The present utility model is further configured such that the processing mechanism further includes one or more groups of wire-embedding assemblies, feeding assemblies, dispensing assemblies, and wire-loosening assemblies.

[0015] Preferably, the wire-embedding assembly includes a pressing member disposed on one side of the annular track and a wire-embedding member disposed on the other side of the annular track. The wire-embedding member includes a wire-pushing cylinder and a pressing block disposed on one side of the wire-pushing cylinder. The position of the pressing block matches the position of the clamping jaw.

[0016] The feeding assembly includes a storage rack and a slide rail disposed between the storage rack and the annular track. A gripper is further provided on the slide rail. The gripper is used to pick up components in the storage rack and mount them on the LED light string.

[0017] The dispensing assembly includes a glue outlet valve and a baking lamp. The dispensing assembly is used to encapsulate the components on the LED light string onto the light string.

[0018] Preferably, one end of the vertical rail is provided with a mounting disc. The mounting disc includes a driving wheel for mounting the LED light roll and a plurality of tension wheels. The other end of the vertical rail is further provided with a storage disc. The storage disc is used to wind up the processed LED light string.

[0019] By adopting the above technical solutions, during the movement of the LED light string in the device, it is cut off at a fixed distance within the light string, and the wires inside the skin wire are exposed. The components are mounted on the wires and welded by the soldering assembly and the welding assembly to enhance the connection strength between the components and the wires. At the same time, after welding, the dispensing assembly encapsulates the connection between the components and the wires, further increasing the overall strength and waterproof performance. Meanwhile, the LED light string is clamped by the clamping jaws in the clamping mechanism and circulates along the annular track. Moreover, the annular track can process two LED light strings simultaneously, with high processing efficiency.

[0020] Furthermore, in order to improve the accuracy of cutting and truncating the LED lamp string and the position of component mounting during the processing, during the processing of the device, the clamping mechanism is driven by a transmission wheel and moves intermittently within the circular track. The LED lamp string is divided into several processing units by the clamping jaws, and the transmission wheel drives the clamping jaws to perform intermittent movement. That is, during the processing, after the clamping mechanism moves a fixed distance, it will stop for a fixed time, enabling the processing mechanism to process each processing unit. At the same time, when the clamping mechanism stops on the circular track, the cutter, solder applicator, soldering iron, and soldering plate in the processing mechanism are all arranged between adjacent clamping jaws. Since the displacement distance of the transmission wheel driving the transmission belt is fixed, that is, after the clamping mechanism stops, the cutter, solder applicator, soldering iron, and soldering plate are all located at fixed positions within the processing unit, making the cutting, soldering, and welding positions the same during processing, thus improving the accuracy of component mounting and welding.

[0021] Meanwhile, before mounting components on the LED lamp string, the cutting assembly performs fixed-point cutting on the LED lamp string. During the cutting process of the cutting assembly, the moving distance of the feed cylinder = the distance of the surface wire layer on the LED lamp string, enabling the cutting assembly to perform surface peeling on the LED lamp string without cutting the internal wires of the LED lamp string, exposing the positions for mounting components on the lamp string, allowing the components to be directly electrically connected to the internal wires of the lamp string, preventing the components in this processing unit from being connected to the wire layer and causing a circuit break, and improving the use effect of the finished product.

[0022] Moreover, the processing mechanism further includes one or more groups of wire embedding components, feeding components, dispensing components, and wire loosening components. The above-mentioned various components cooperate within the processing mechanism. After the LED lamp string is fed by the wire embedding component and clamped by the clamping mechanism, through the processing of each component, peeling, cutting, feeding, soldering, and plastic sealing of the LED lamp string are realized. By replacing the stranded connection of multiple wires with the truncating and soldering of the lamp string, the processing efficiency is high and the effect of the finished product is good.

[0044] During the movement of the LED light string in the device, it is cut off at a fixed distance in the light string to expose the wire in the skin wire. The components are mounted on the wire and welded by the soldering assembly 42 and the welding assembly 43 to enhance the connection strength between the components and the wire. At the same time, after welding, the dispensing assembly 46 encapsulates the connection between the components and the wire to further increase the overall strength and waterproof performance. At the same time, the LED light string is clamped by the claws 32 in the clamping mechanism 3 and circulates along the annular track 2. The annular track 2 can process two LED light strings simultaneously, and the processing efficiency is high.

[0045] Further, in order to improve the accuracy of cutting and truncating the LED lamp string and the position of component mounting during the processing, during the processing of the device, the clamping mechanism 3 is driven by a transmission wheel 7 and moves intermittently within the circular track 2.

That is, during the processing, after the clamping mechanism 3 moves a fixed distance, it will stop for a fixed time, enabling the processing mechanism 4 to process each processing unit.

During the cutting process of the cutting assembly 41, the moving distance of the feed cylinder 4121 = the distance of the surface wire layer on the LED lamp string, enabling the cutting assembly 41 to perform surface skin - removing operation on the LED lamp string without cutting the internal wires of the LED lamp string, exposing the positions for mounting components on the lamp string, enabling the components to be directly electrically connected to the internal wires of the lamp string, preventing the components in this processing unit from being connected to the wire skin layer and causing a circuit open - circuit, and improving the use effect of the finished product.

[0047] Moreover, the processing mechanism 4 further includes one or more groups of wire - embedding components 44, feeding components 45, glue - dispensing components 46, and wire - loosening components 47.

After the LED lamp string is fed by the wire - embedding component 44 and clamped by the clamping mechanism 3, through the processing of each component, skin - removing, cutting, feeding, soldering, and plastic - encapsulating of the LED lamp string are realized. By replacing the stranding connection of multiple wires with the truncating and soldering of the lamp string, the processing efficiency is high and the effect of the finished product is good.

[0048] During the processing of the LED light string by the above device, the clamping mechanism 3 moves within the annular track 2, and the clamping mechanism 3 moves along a first direction on the first vertical track 21 of the annular track 2, and the clamping mechanism 3 moves along a second direction on the second vertical track 21 of the annular track 2. The first direction is opposite to the second direction. That is, within the annular track 2, the end of the first vertical track 21 is connected to the start end of the second vertical track 21 through a curved track 22, and mounting disks 8 for placing raw material light string rolls and storage disks 9 for winding finished light strings are provided at both ends of the vertical track 21. At the start end of the vertical track 21, the light string in the mounting disk 8 is installed in the clamping mechanism 3 through the wire embedding assembly 44. At the same time, the clamping mechanism 3 slides on the vertical track 21 to the end to complete production. At the same time, the wire releasing assembly 47 at the end controls the light string to fall off from the clamping mechanism 3 and be wound and stored in the storage disk 9. At the same time, the clamping mechanism 3 after the wire releasing is completed moves from the end of the vertical track 21 to the start end of the other vertical track 21 through the curved track 22 to complete the clamping and processing of the light string within the other vertical track 21.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
