Description

Technical fields:

[0001] This utility model relates to a laser cutting device for touch screen production. Background technology:

[0002] A touch screen, also known as a touch panel, is a sensor-type liquid crystal display device that can receive input signals from touch. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connected devices according to a pre-programmed program. It can replace mechanical button panels and create vivid audio-visual effects through the liquid crystal display screen.

[0003] Before being formed, touchscreens need to be laser-cut to the required size. Currently, most methods involve clamping the horizontally placed touchscreen from both sides using a clamping structure. Then, a laser cutter positioned above the touchscreen moves left, right, front, and back to complete the cut, as illustrated by a touchscreen cutting device disclosed in Chinese Patent Publication No. CN222269033U. However, this patent lacks a structure to receive and support the cut touchscreen. After laser cutting, the touchscreen must be manually supported until the clamping structure releases before it can be removed. This method is inconvenient and requires all cut touchscreens to be removed before the next operation can begin, resulting in inefficient work. Therefore, it is necessary to improve this technology. Utility model content:

[0004] This utility model addresses the problems existing in the prior art by providing a laser cutting device for touch screen production.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a laser cutting device for touch screen production, comprising a worktable disposed directly below a laser cutter, a clamping structure for holding a horizontally placed touch screen from the left and right sides on the top of the worktable, a downwardly recessed cavity on the top of the worktable, a support plate for receiving the cut touch screen horizontally disposed inside the cavity, the support plate being driven upward by a lifting component to contact the bottom of the cut touch screen, the support plate and the lifting component being driven left and right by a lateral moving component, and an opening at the left end of the cavity to facilitate the support plate moving to the left and passing through.

[0006] Furthermore, the lifting assembly includes a pair of lifting cylinders distributed on the left and right. The lifting cylinders are arranged vertically, and the cylinder rods of the pair of lifting cylinders extend upward and are connected to the bottom of the support plate. The pair of lifting cylinders drive the support plate to move up and down.

[0007] Furthermore, the lateral movement assembly is a ball screw nut pair that is laterally installed in the middle of the bottom surface of the cavity. The left end of the ball screw nut pair extends out of the cavity, and a movable seat is fixed to the top of the nut of the ball screw nut pair. A pair of lifting cylinders are installed on the top of the movable seat.

[0008] Furthermore, the clamping structure is located directly above the cavity. The clamping structure includes a pair of clamping plates distributed on the left and right. The pair of clamping plates are driven to move left and right by a horizontally arranged electric telescopic rod. The electric telescopic rod is mounted on a fixed base plate, and the fixed base plate is fixed to the top of the worktable.

[0009] Furthermore, the cavity is in the shape of a rectangular groove.

[0010] Compared with the prior art, the present invention has the following advantages: The present invention has a reasonable structural design. It uses a liftable support plate to support the cut touch screen. Then, the horizontal moving component drives the support plate and the cut touch screen to move to the left out of the worktable. The entire material handling process does not require manual support of the touch screen. After the cut touch screen moves out of the worktable, it does not affect the clamping structure to clamp the next touch screen, which facilitates the quick execution of the next cutting operation and improves work efficiency.

[0012] Figure 2 This is a top view of an embodiment of the present invention. Detailed implementation method:

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] like Figures 1-2As shown, this utility model discloses a laser cutting device for touch screen production, including a worktable 1 horizontally positioned directly below a laser cutter 2. The laser cutter can move in the front-back and left-right directions. The top of the worktable 1 is provided with a clamping structure for holding a horizontally placed touch screen 4 from the left and right sides. The top of the worktable 1 is provided with a downwardly recessed cavity 3, the position of which corresponds to the position of the clamping structure. Inside the cavity 3, a support plate 5 is horizontally positioned to receive the cut touch screen. The support plate 5 is driven upward by a lifting component and contacts the bottom of the cut touch screen. The support plate 5 and the lifting component are driven left and right by a lateral moving component. The left end of the cavity 3 has an opening 6 to facilitate the support plate moving to the left and passing through. That is, the support plate moves the cut touch screen to the left out of the cavity, and the cut touch screen can be manually removed from the support plate on the left side of the cavity.

[0016] During operation, the entire touchscreen to be cut is held by a clamping structure from both sides, with the support plate initially positioned directly below the touchscreen. The laser cutter then cuts the touchscreen held by the clamping structure from left to right. After all cutting is complete, the lifting component drives the support plate upwards, bringing its top into contact with the bottom of the touchscreen. The clamping structure releases the touchscreen, allowing the support plate to fully support the cut touchscreen. Next, the lifting component drives the support plate and the cut touchscreen downwards until the touchscreen is inside a recessed cavity. Finally, the lateral movement component moves the support plate and the cut touchscreen to the left out of the cavity, allowing a manual removal of the cut touchscreen from the support plate on the left side of the cavity. This device utilizes a liftable support plate to hold the cut touchscreen, and then the lateral movement component moves the support plate and the cut touchscreen to the left out of the worktable. The entire unloading process requires no manual support of the touchscreen, and after the cut touchscreen moves out of the worktable, it does not affect the clamping structure's ability to hold the next touchscreen, facilitating quick and efficient subsequent cutting operations and improving work efficiency.

[0017] In this embodiment, the lifting assembly includes a pair of lifting cylinders 7 distributed on the left and right. The lifting cylinders 7 are arranged vertically, and the cylinder rods of the pair of lifting cylinders 7 extend upward and are connected to the bottom of the support plate 5. The pair of lifting cylinders 7 drive the support plate 5 to move up and down.

[0018] In this embodiment, the lateral movement component is a ball screw nut assembly 8 horizontally installed in the middle of the bottom surface of the cavity 3. The left end of the ball screw nut assembly 8 extends out of the cavity, and a movable seat 9 is fixed to the top of the nut of the ball screw nut assembly 8. A pair of lifting cylinders 7 are installed on the top of the movable seat 9. The ball screw nut assembly drives the pair of lifting cylinders and the support plate to move left and right through the movable seat.

[0019] In this embodiment, the clamping structure is located directly above the cavity 3. The clamping structure includes a pair of clamping plates 10 distributed on the left and right. The pair of clamping plates 10 are driven to move left and right by a horizontally arranged electric telescopic rod 11. The electric telescopic rod 11 is mounted on a fixed base plate 12, and the fixed base plate 12 is fixed to the top of the workbench 1.

[0020] In this embodiment, the concave cavity 3 is in the shape of a rectangular groove.

[0021] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0022] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0023] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
