Description

Technical Field

[0001] This utility model relates to the field of backlight keyboard technology, specifically a backlight panel positioning and film-peeling device. Background Technology

[0002] Backlit keyboards are computer peripherals that illuminate the keys using LEDs placed below them or along the edges of the keyboard panel. Their core function is to provide clear key visibility in low-light environments. This design originated from the demand for multi-functional keyboards driven by the gaming market. Through technological breakthroughs such as light adjustment and color diversity, it has gradually evolved into a peripheral category that balances practicality and aesthetics. Operationally, brightness and lighting modes can be adjusted via key combinations or dedicated software to meet the needs of various scenarios, including nighttime office work and e-sports gaming.

[0003] A backlit keyboard, a computer peripheral that provides key recognition in low-light environments, consists of a keycap assembly and a backlight panel. The backlight panel is illuminated by LEDs located below or along its edges, and the keycap assembly and backlight panel are attached to form a complete backlit key structure. To meet the needs of various scenarios such as nighttime office work and e-sports gaming, backlit keyboards require adjustments to brightness and lighting modes via key combinations or dedicated software. Therefore, the precision required for the fit between the keycap assembly and the backlight panel is extremely high.

[0004] In current backlit keyboard production, the adhesive layer of the backlight panel (used for bonding with the keycap assembly) needs to be covered with an anti-stick film during transportation to prevent multiple backlight panels from sticking together. Before bonding the keycap assembly to the backlight panel, this anti-stick film must be removed, and the accurate positioning of the backlight panel must be ensured. Currently, the above-mentioned film removal and positioning processes mostly rely on manual operation: workers manually place the backlight panel at the bonding station, visually align it with the positioning marks to complete the initial positioning, and then manually remove the anti-stick film.

[0005] However, manual operation has the following drawbacks:

[0006] 1. Low efficiency: The positioning and film removal of a single backlight panel takes a long time, making it difficult to adapt to large-scale production lines.

[0007] 2. Poor positioning accuracy makes it easy for the naked eye to align the backlight panel and keycaps, resulting in misalignment after bonding, which affects the uniformity of the lighting and the feel of the keys.

[0008] 3. Unstable film tearing quality: Uneven force when manually tearing the film can easily damage the adhesive layer or leave some film fragments, which further affects the reliability of the bonding.

[0009] Therefore, there is an urgent need for a device that can automatically position and peel off the backlight panel to solve the problems of low efficiency, poor accuracy, and unstable quality in the existing technology. Utility Model Content

[0010] This utility model discloses a backlight panel positioning and film-tearing device, which overcomes the defects of manual positioning and film-tearing in the production of existing backlight keyboards.

[0011] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0012] This utility model discloses a backlight panel positioning and film-tearing device, including a feeding and positioning mechanism and a film-tearing mechanism, wherein the film-tearing mechanism is located at the rear end of the feeding and positioning mechanism, wherein:

[0013] The material feeding and positioning mechanism includes a backlight adsorption device, a backlight pressure plate, and a backlight positioning block. The backlight adsorption device is set horizontally. One end of the backlight positioning block is installed on a mounting block. Mounting block one is installed on the output end of vertical cylinder one. The backlight pressure plate is installed at the lower end of the pressure plate mounting plate. One side of the pressure plate mounting plate is installed on a connecting plate. Connecting plate one is installed on the output end of cylinder two.

One end of the finger cylinder mounting plate is installed at the output end of the rotary cylinder, and the other end of the finger cylinder mounting plate is installed with the finger cylinder. Two clamping blocks are installed at the output end of the finger cylinder.

[0015] Furthermore, the backlight adsorption device includes a suction cup mounting top plate, the lower end of the suction cup is mounted on the suction cup mounting block, the top of the suction cup passes through the suction cup mounting top plate, the suction cup mounting block is provided with a gas channel corresponding to the suction cup, the suction cup mounting top plate is mounted on the top of the suction cup mounting block, the gas channel is connected to a pipe, and one end of the pipe is installed at the ventilation chamber.

[0016] Furthermore, the bottom of both the ventilation chamber and the suction cup mounting block are mounted on a movable plate. Slider blocks are mounted on both sides of the bottom of the movable plate. The sliders are slidably connected to the guide rail. A lead screw nut is mounted on the bottom of the movable plate. The lead screw nut is connected to the lead screw. Both ends of the lead screw are mounted on bearing seats. One end of the lead screw is connected to the drive motor.

[0017] Furthermore, there are two backlight panel positioning blocks arranged in parallel, with the two backlight panel positioning blocks installed on both sides of the mounting block one, and the backlight panel pressure plate located between the two backlight panel positioning blocks.

[0018] Furthermore, the backlight plate is mounted on the lower end of the pressure plate mounting plate by two springs. The pressure plate mounting plate is equipped with two guide posts, and the backlight plate is connected to the guide posts, which pass through the springs.

[0019] Furthermore, the pressure plate mounting plate is provided with a sliding groove and a guide post through groove. The sliding groove is located at the upper end of the guide post through groove, and the diameter of the sliding groove is larger than that of the guide post through groove. A sliding block is installed on the outer side of the upper end of the guide post, and the diameter of the sliding block matches that of the sliding groove. The top of the spring is installed at the bottom of the sliding block, and a cover is installed on the top of the sliding block.

[0020] Furthermore, the finger cylinder is installed at the output end of the rotary cylinder two, which is mounted on the finger cylinder mounting plate.

[0021] Furthermore, a sensor plate is installed on one side of the movable plate, and a sensor corresponding to the sensor plate is provided at the lower end of one side of the guide rail.

[0022] The beneficial effects of this utility model are:

[0023] To improve production efficiency, the device uses finger cylinders and clamping blocks to clamp the film. The rotating cylinder works, driving the finger cylinders to rotate. At the same time, the lead screw rotates, moving the entire device to complete the film tearing process and improving the film tearing efficiency.

[0024] To improve positioning accuracy, the suction cup performs initial positioning, and then the backlight plate pressure plate presses the backlight plate firmly to ensure that the suction cup can completely hold the backlight plate and guarantee the positioning accuracy of the material feeding.

[0025] To ensure stable film tearing quality, a rotary cylinder is used for initial demolding, followed by horizontal movement to achieve final demolding. This avoids the problem of uneven force when manually tearing the film, resulting in no damage to the adhesive layer, no film residue, and improved bonding yield.

[0026] Reduce labor costs: The equipment can operate unmanned, reducing labor input and avoiding fatigue errors from manual operation, thus improving production stability. Attached Figure Description
