Description

Technical Field

[0001] The utility model relates to the technical field of projection screen laminating, in particular to a large-size laser projection screen laminating device. Background Art

[0002] Laser TVs have developed rapidly due to their advantages such as wide color gamut, high brightness, long service life, energy saving, and environmental protection. A laser TV includes a projector (laser) and a projection screen used in cooperation with the projector. During use, the projection screen is usually installed on a wall, and the light projected by the projector onto the projection screen is reflected by the projection screen and then enters the eyes of the audience along a set optical path, thereby generating an image.

[0003] Currently, the projection screens on the market mainly include two types: soft screens and hard screens. The hard screen includes an optical film and a back plate. The back plate is made of a rigid material, and the optical film is adhesively bonded to the back plate with glue. Then, frames are assembled around the hard screen to play a role in shielding and decoration. However, since the hard screen for laser TVs is large in size, and because the back plate of the hard screen in the prior art is a rigid whole, and the optical film has been adhered to the back plate at the time of leaving the factory, this will result in a large overall weight and size of the hard screen. Therefore, it is difficult to handle the hard screen and bring it into the user's home, which will seriously restrict the development of the entire projection industry.

[0004] The soft screen includes a screen body and a support frame. The screen body can be bent, and the support frame can be disassembled, which is convenient to enter the user's home. The screen body is fixed by adhesively bonding a base cloth and a film. Generally, the base cloth is fully coated with adhesive and then bonded and fixed with the film. Since there is glue around the film in the full-back-adhesive production process, it will cause great operation difficulty, high rejection rate, and high cost in the subsequent production process.

[0005] In view of the above problems, the production of soft screens requires a laminating device that can achieve local back-adhesive of the base cloth. Summary of the Invention

[0006] The purpose of the utility model is to provide a large-size laser projection screen laminating device, which can achieve local back-adhesive of the base cloth and the lamination is flat and firm.

[0007] To achieve the above purpose, the utility model provides a large-size laser projection screen laminating device, which includes a frame and a pressing mechanism. Removable guard plates are arranged on both sides of the frame. The pressing mechanism is arranged on the frame. An outfeed conveyor is arranged on the left side of the pressing mechanism. An auxiliary mechanism is further included;

[0008] The auxiliary mechanism includes an upper platform, a suction belt, a conveyor belt, a signal frame, a fitting shaft, a suction cup device and a gas supply device. The upper platform is arranged on one side of the frame. The suction belt is arranged on the side of the frame close to the upper platform. The conveyor belt is arranged on one side of the frame. The signal frame is fixedly connected to the frame and is located on both sides of the frame. The fitting shaft is located on one side of the signal frame. A pressing wheel assembly is arranged on one side of the fitting shaft. The suction cup device is arranged on the right side of the frame. The gas supply device is arranged on one side of the suction cup device.

[0009] Among them, the suction cup device includes a suction cup frame, a downward cylinder and a moving component. The suction cup frame is located on one side of the signal frame. The output end of the downward cylinder is connected to the suction cup frame and is located above the suction cup frame. The moving component is arranged on the right side of the downward cylinder.

[0010] Among them, the moving component includes a fixed plate and a driving frame. The fixed plate is fixedly connected to the frame and is located on both sides of the frame. The driving frame is fixedly connected to the downward cylinder and is arranged on one side of the fixed plate.

[0011] Among them, the gas supply device includes a support frame and a gas distribution component. The support frame is fixedly connected to the frame and is located on both sides of the frame. The gas distribution component is arranged on the side of the support frame close to the suction cup frame.

[0012] Among them, the gas distribution component includes a conduit and a tracheal joint. The conduit is fixedly connected to the support frame and is located on the support frame. The tracheal joint is threadedly connected to the conduit and is located on the conduit. The tracheal joint is connected to the quick connector of the top trachea of the suction cup on the suction cup frame through a rubber trachea.

[0013] The utility model discloses a large-size laser projection screen bonding equipment. Removable guard plates are arranged on both sides of the frame. The pressing mechanism is arranged on the frame. A discharging conveyor is arranged on the left side of the pressing mechanism. The cut double-sided tape is placed on the workbench. At this time, the double-sided tape is in the state of one side being the release paper of the tape and the other side being the release film. A front end part of the double-sided tape is placed on the suction belt of the bonding equipment with the release paper facing upwards. The suction is turned on to peel off the release paper of the double-sided tape. The cut cloth is placed on the upper platform. The platform is divided into two parts, the upper one is for the cloth and the lower one is for the suction belt. The double-sided tape is placed and the cloth is conveyed. The belt starts to run, and the double-sided tape moves forward with the rotation of the conveyor belt. When the signal rack detects the signal, the conveyor belt stops, and the suction cup rack drives the suction cup to operate, sucking up the cloth placed on the upper platform and placing it at the set position at the front end of the double-sided tape. After placement, the suction cup rack returns to the initial position, and the pressure wheel assembly moves and presses down on the cloth. The bonding shaft is removed and placed on the cloth. The equipment switch is pressed to start the suction belt. The double-sided tape and the cloth are bonded together by the bonding shaft weight pressure, and finally pressed together by the pressing mechanism. After processing is completed, it is transported out through the discharge conveyor, so that the base layout can be partially glued and the bonding is flat and firm.
