Description

Technical Field

[0001] This utility model relates to the field of display screen coating technology, and in particular to an automatic LED display screen packaging coating machine. Background Technology

[0002] An automatic LED display packaging laminating machine is a specialized device for automatically completing the laminating operation during the packaging process of LED displays. LED displays are susceptible to dust, moisture, and impacts during transportation and storage. The film used in the automatic laminating machine has excellent waterproof, dustproof, and abrasion-resistant properties, forming a physical barrier to protect the screen surface from damage and extend the product's lifespan. Manual lamination is prone to errors such as improper film cutting or repeated lamination. The automatic laminating machine, through precise control of film usage and cutting accuracy, reduces material waste. Automated lamination ensures consistent packaging quality for each product, meeting industry standards and customer requirements, and is particularly suitable for high-end LED display products with high requirements for packaging precision and appearance.

[0003] However, existing technologies, such as Chinese Announcement No. CN208217090U, "A Mobile Phone Tempered Glass Display Screen Coating and Packaging Equipment," disclose a mobile phone tempered glass display screen coating and packaging equipment. This equipment includes a machine base, with a first raw material placement area and a second raw material placement area respectively located at the head and middle sections of the machine base for placing protective films. A display screen placement area is located between the first and second raw material placement areas. The protective film from the first raw material placement area passes through the display screen placement area and, together with the protective film from the second raw material placement area, passes through a roller assembly and is then conveyed to a photosensitive cutting device at the tail of the machine base. This invention automatically slices individual products through mechanical pressing, improving production efficiency and saving labor costs.

[0004] However, this device lacks a central clamping structure for propulsion linkage, which cannot ensure that the display screen remains centered and fixed during the transfer process. This leads to skewed lamination due to offset, preventing the screen from moving smoothly to the lamination station at a constant speed. This may cause screen transfer to stall or fluctuate in speed, thus affecting the uniformity of film lamination. It fails to solve the problems of positional offset and unstable transfer of LED displays during the lamination process. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art, which cannot ensure that the display screen remains in a fixed center position during the transmission process, resulting in skewed film coating due to offset. This prevents the screen from moving smoothly to the coating station at a constant speed, which may cause screen transmission jams and speed fluctuations, thereby affecting the uniformity of film bonding. It does not solve the problems of position offset and unstable transmission of LED display screens during the coating process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic laminating machine for LED display packaging, comprising a worktable, a through groove on the worktable, and limit grooves on both sides of the through groove. Limit plates are movably embedded in the limit grooves, and movable plates are fixedly connected to the inner sides of the two limit plates. A rotating rod is rotatably connected inside the movable plate, and a rotating assembly is provided at the bottom of the rotating rod. The rotating assembly includes a gear, the top of which is fixedly connected to the bottom of the rotating rod. A rack is meshed with the outer surface of the gear, and two connecting plates are fixedly connected to the top of the rack. The tops of the two connecting plates are fixedly connected to the top of the worktable. When moving simultaneously, the meshing action of the rack and gear will drive the rotating rod to rotate inside the movable plate.

[0007] In a preferred embodiment, a synchronizing rod is fixedly connected to the top of the rotating rod, and connecting rods are rotatably connected to both ends of the synchronizing rod. A follower rod is rotatably connected to the end of the connecting rod away from the synchronizing rod, and a wedge is fixedly connected to the bottom of the follower rod. Two wedge slots are formed on the moving plate, and the outer surface of the wedge is movably embedded in the wedge slot. The other end of the connecting rod pushes the follower rod, causing the follower rod and the wedge to move along the slotting direction of the wedge, and causing the two side plates to move closer to the center at the same time.

[0008] In a preferred embodiment, a side plate is fixedly connected to the top of the follower rod, and a positioning rod is movably embedded inside the side plate. One end of the two positioning rods is fixedly connected to an elastic clamping plate, and the end of the positioning rod away from the elastic clamping plate is fixedly connected to a force-bearing plate. According to the size of the film-applying equipment required for this batch, a positioning rod and spring of appropriate length are selected to ensure that the elastic clamping force applied during clamping is moderate.

[0009] In a preferred embodiment, a spring is movably sleeved on the outer surface of the positioning rod. The ends of the two springs away from the force plate are fixedly connected to one side of the side plate, and the other ends of the springs are fixedly connected to one side of the force plate. The springs on the force plate side can provide a certain elastic movement space for the equipment, allowing the equipment to have a certain dimensional error.

[0010] In a preferred embodiment, a threaded rod is rotatably connected inside the through groove and extends out one end. The outer surface of the threaded rod is threadedly connected to the inside of the movable plate. Rotating the thread will drive the movable plate, causing the movable plate and the limiting plate to move along the slotting direction of the limiting groove.

[0011] In a preferred embodiment, a mounting sleeve is fixedly connected to one side of the workbench, and a motor is fixedly embedded in the inner surface of the mounting sleeve. The output end of the motor is fixedly connected to one end of the threaded rod. When the motor is powered on, it will drive the threaded rod to rotate inside the through groove.

[0012] In a preferred embodiment, the bottom of the workbench is fixedly connected to multiple support legs, and the top of the workbench is fixedly connected to a film applicator body. The film applicator body, as an existing device and technology, can apply a film to the outer surface of the equipment.

[0013] In a preferred embodiment, a pressure-bearing shell is fixedly connected to the top of the movable plate, and a stop plate is fixedly connected to the top of the pressure-bearing shell. The equipment to be applied to is placed on the top of the pressure-bearing shell and on one side of the stop plate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This utility model features a device with a central clamping structure that ensures the display screen remains centered and fixed during transport, preventing misalignment during film lamination. It enables the screen to move smoothly to the lamination station at a constant speed, avoiding screen transport jams and speed fluctuations that could affect the uniformity of film lamination. This solves the problems of positional shift and unstable transport of LED displays during the lamination process. Attached Figure Description
