Description

Technical Field

[0001] This utility model relates to the field of plastic LED strip extrusion molding technology, and in particular to an integrated plastic LED strip extrusion molding machine. Background Technology

[0002] An integrated plastic LED strip extrusion molding machine is a specialized piece of equipment used for the automated production of integrated plastic LED strips. Its function is to integrate and install the LED strip on the top wall inside a PC base, then assemble the PC cover with the PC base, and finally achieve one-piece molding of the PC cover through an extrusion process. It is commonly used in large-scale production scenarios for LED lighting equipment.

[0003] However, because the PC base and PC cover typically require an interference fit to ensure structural stability and sealing, after the PC cover is extruded, it needs to be pressed and assembled with the PC base. Usually, the extrusion and pressing processes are separate, resulting in an excessively long production line and hindering production efficiency. Furthermore, traditional pressing methods relying on manual labor or simple tooling make it difficult to precisely control the force and stroke during the pressing process. Uneven force applied by the operator or slight angle deviations can easily lead to excessive local stress in the PC cover, causing invisible micro-cracks or inconsistent panel embedding depths. This not only results in low efficiency but also affects the quality and long-term reliability of the final product. Utility Model Content

[0004] The purpose of this invention is to provide an integrated plastic LED strip extrusion molding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integrated plastic LED strip extrusion molding machine includes an extruder, wherein two conveyor belts are provided on one side of the discharge port of the extruder, and a pressing assembly is provided between the two conveyor belts, the pressing assembly including two pressure plates arranged above and below.

[0007] A PC base and a PC cover are provided, with a COB light strip between them. Both ends of the PC base and the PC cover are provided with end caps. A pressing assembly is used to press the PC base and the PC cover together. A robotic arm is provided on one side of the pressing plate. A punching machine is provided above the conveyor belt that is furthest from the extruder.

[0008] Preferably, the pressure plate is provided with a material receiving groove.

[0009] Preferably, several pressure blocks are fixedly installed on the side of the two pressure plates that are far apart from each other.

[0010] Preferably, several pressure blocks located on the same side are connected by a connecting rod.

[0011] Preferably, the pressing assembly includes a mounting base, a T-shaped shell is fixedly mounted on the top of the mounting base, a sliding groove is provided on the side wall of the T-shaped shell, the connecting rod slides through the sliding groove, a sliding seat is slidably mounted inside the T-shaped shell, a slot is provided at one end of the sliding seat near the connecting rod, two hinge rods are hinged in the slot, and the other ends of the two hinge rods are respectively rotatably sleeved on the middle sections of the upper and lower connecting rods.

[0012] Preferably, a cylinder is fixedly installed at the end of the sliding seat away from the pressure plate, and the piston rod of the cylinder is fixedly connected to the end of the sliding seat.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. By using symmetrically arranged pressure plates, pressure blocks, and connecting rods in the pressing assembly, and in conjunction with the pressing assembly consisting of a cylinder-driven sliding seat and hinge rod, the automatic pressing of the PC base and PC cover is achieved, replacing the traditional manual assembly process of PC base and PC cover. This not only significantly reduces labor costs, but also ensures the accuracy of the snap-fit ​​position and the consistency of assembly quality through uniform pressure, effectively avoiding finished product quality problems caused by uneven manual operation.

[0015] 2.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] An integrated plastic LED strip extrusion molding machine, such as Figures 1-6 As shown, it includes:

[0028] The extruder 2 has two conveyor belts 3 on one side of the discharge port, and a pressing assembly 1 is provided between the two conveyor belts 3. The pressing assembly 1 includes two pressure plates 17 arranged vertically.

[0029] PC base 6 and PC cover 7 are connected by a COB LED strip 9. The bottom of PC base 6 is open, and PC cover 7 is snapped into the opening. The COB LED strip 9 is pre-installed between PC base 6 and PC cover 7. Both ends of PC base 6 and PC cover 7 are provided with plugs 8. Press assembly 1 is used for pressing PC base 6 and PC cover 7. A robotic arm 4 is provided on one side of pressure plate 17. A punching machine 5 is provided above the one of the two conveyor belts 3 that is away from extruder 2. PC cover 7 is produced by extrusion by extruder 2. The conveyor belt 3 is used to push PC cover 7 forward along the production line. When PC cover 7 produced by extruder 2 falls onto the lower pressure plate 17 under the push of conveyor belt 3, the upper and lower pressure plates 17 apply pressure together to make PC cover 7 embed into the groove of PC base 6, completing the snap-fit ​​assembly between the two. After the assembly is completed, the two plugs 8 are installed at both ends of PC cover 7 and PC base 6 by external device.

[0030] A robotic arm 4 is provided on one side of the pressure plate 17. The robotic arm 4 places the PC base 6 between the upper and lower pressure plates 17 and positions it accurately above the PC cover 7. After the pressing assembly 1 completes the pressing assembly of the PC base 6 and the PC cover 7, the robotic arm 4 moves the finished one-piece plastic light strip to another set of conveyor belts 3.

[0031] A punching machine 5 is installed above the conveyor belt 3 furthest from the extruder 2. The punching machine 5 uses its internal pneumatic grippers to grab the integrated plastic light strip and move it to the punching area. It uses its integrated punching components to punch holes at both ends of the PC cover 7 at the bottom of the integrated plastic light strip. The extruder 2 has an automatic cutting function for the molded PC cover 7. The conveyor belt 3 uses a clamping structure on top to ensure that the transported PC cover 7 is always in the middle of the conveying path to avoid deviation. By integrating the extruder 2, conveyor belt 3, pressing component 1, robotic arm 4 and punching machine 5, a complete production line is constructed. From the extrusion production of PC cover 7 to the automatic pressing and assembly with PC base 6, and then to the punching of the finished product, all processes are seamlessly connected. This replaces the manual handling, alignment and assembly links between processes in the traditional mode, realizes automated processing from raw materials to finished products, and effectively improves production efficiency.

[0032] The pressure plate 17 is provided with a material picking slot. The robotic arm 4 uses its gripper to accurately place the PC cover 7 into the designated position on the lower pressure plate 17 through the material picking slot. After the pressing assembly 1 completes the pressing and assembly of the PC base 6 and the PC cover 7, the gripper of the robotic arm 4 once again uses the material picking slot to take out the finished one-piece plastic light strip and move it to another conveyor belt 3 downstream.

[0033] Several pressure blocks 16 are fixedly installed on the side of the two pressure plates 17 that are far apart from each other. By driving the corresponding upper and lower pressure blocks 16 to move closer to each other, the pressure plates 17 connected to them are directly driven to move towards each other. Finally, the two pressure plates 17 squeeze the PC base 6 and PC cover 7 from the upper and lower sides to complete the snap-fit ​​assembly.

[0034] Several pressure blocks 16 located on the same side are connected by a connecting rod 18, so that when the connecting rod 18 is in motion, it can drive the multiple pressure blocks 16 on the same side to move synchronously, ensuring that these pressure blocks 16 can move closer to each other in a coordinated manner.

[0035] The pressing assembly 1 includes a mounting base 11, on the top of which a T-shaped shell 12 is fixedly mounted. A groove is provided on the side wall of the T-shaped shell 12, through which the connecting rod 18 slides. A sliding seat 14 is slidably mounted inside the T-shaped shell 12. A slot is provided at one end of the sliding seat 14 near the connecting rod 18, and two hinge rods 15 are hinged in the slot. The other ends of the two hinge rods 15 are respectively rotatably sleeved on the middle sections of the upper and lower connecting rods 18. When the sliding seat 14 moves away from the pressure plate 17 inside the T-shaped shell 12, it will pull the two hinge rods 15 to move. Since the two ends of the hinge rods 15 are hinged to the sliding seat 14 and the connecting rods 18 respectively, the hinge rods 15 will bring the upper and lower connecting rods 18 closer to each other. The groove on the side wall of the T-shaped shell 12 restricts and guides the movement path of the connecting rods 18, ensuring that they slide stably up and down according to a preset trajectory.

[0036] A cylinder 13 is fixedly installed at the end of the sliding seat 14 away from the pressure plate 17. The piston rod of the cylinder 13 is fixedly connected to the end of the sliding seat 14. Through the extension and retraction of the piston rod, the sliding seat 14 is driven to reciprocate linearly inside the T-shaped shell 12. In turn, through the above steps, the two pressure plates 17 are driven to press the PC base 6 and the PC cover 7 simultaneously.

[0037] The working principle of the integrated plastic LED strip extrusion molding machine provided by this utility model is as follows:

[0038] First, the extruder 2 injects molten plastic into the mold and automatically cuts the formed PC cover 7. By using the extrusion process provided by the extruder 2, it can be ensured that the PC cover 7 has a highly consistent cross-sectional size and wall thickness throughout its length, thus ensuring the stability of product quality. At the same time, the extrusion process can produce a constant cross-sectional shape. For example, the edge cross-section of the PC cover 7 is extruded into an arc shape, which makes it easier to press into the groove of the PC base 6.

[0039] Subsequently, the formed PC cover 7 is received by the conveyor belt 3 on the side of the discharge port and conveyed forward until it is pushed onto the pressure plate 17 directly below the pressing assembly 1.

[0040] Simultaneously, the robotic arm 4 places the PC base 6 on its gripper above the PC cover 7. At this time, the cylinder 13 pulls the sliding seat 14 at its front end backward in a straight line within the T-shaped shell 12 by retracting the piston rod. The sliding seat 14 pulls the two hinge rods 15 to swing around their hinge point and converts the horizontal pulling force into the vertical opposite movement of the two connecting rods 18. Under the guidance of the slide groove of the T-shaped shell 12, the connecting rods 18 drive all the pressure blocks 16 on the same side to move closer to each other synchronously. Finally, the two pressure plates 17 together clamp the PC base 6 and the PC cover 7, pressing and snapping them together to assemble them into an integrated plastic light strip.

[0041] After assembly, the gripper of the robotic arm 4 takes out the finished one-piece plastic light strip through the material picking groove on the pressure plate 17 and moves it to another conveyor belt 3 downstream. The conveyor belt 3 transports the finished product to the punching station, where the pneumatic gripper of the punching machine 5 grabs and moves it, and uses its punching component to punch holes at both ends of the bottom of the PC cover 7, finally completing all processing.

[0042] The basic working principle of extruder 2 is to mold thermoplastic or thermosetting plastics into products of a specific shape in a mold through stages such as heating, melting, injection, pressure holding, and cooling. In this molding machine, it is used to produce PC cover 7 and has an automatic cutting function for the molded products. Conveyor belt 3, as a continuous material conveying device, is used to transfer workpieces between various workstations in the production line. In this molding machine, the clamps on conveyor belt 3 are used to ensure that the workpieces are centered during the conveying process and to prevent deviation. Robotic arm 4, as a general industrial robot, can perform repetitive operations such as gripping, handling, and placing through programming control. In this molding machine, robotic arm 4 uses the gripper at its end to perform loading and unloading tasks. Drilling machine 5 is an automated drilling unit that integrates a power head and a special fixture. In this molding machine, drilling machine 5 grips the workpiece through its internal pneumatic gripper and drives the drill bit to drill holes in PC cover 7. All of the above components are widely used technologies in this field, and their specific structures and working principles are existing technologies in this field and will not be described in detail here. The specific model of cylinder 13 is SMC. CY1S32-50-M5.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
