Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically a device for lifting sheet materials. Background Technology

[0002] Sheet protective film, also known as sheet material, is primarily used after the electronic product manufacturing process to affix it to the outer casing of electronic products, such as computer screens or the exterior of computer plastic casings. This prevents scratches and dust from entering the electronic product during subsequent transportation, achieving the desired protective purpose. Sheets are cut to size according to the specific product, and large quantities of sheets of the same size are stacked and stored. When needed, a certain number of stacked sheets are transferred to a location accessible to the appropriate equipment for retrieval. Typically, sheet materials are stored or transferred using a hopper. Once the sheet material reaches the designated location, appropriate equipment continuously retrieves the top layer of sheet material from the hopper; for example, a robotic arm with suction cups can be used to pick up the top layer of sheet material.

[0003] However, as the sheet material is continuously used, the stacked sheet material height will gradually decrease, resulting in a problem where the corresponding equipment has too large a height difference and it is difficult to pick up the material. Utility Model Content

[0004] This utility model mainly provides a sheet material lifting device to solve the problem that as the sheets are continuously taken out, the height of the stacked sheets gradually decreases, resulting in a large height difference in the corresponding equipment, making it difficult to pick up the materials.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A sheet material lifting device includes a hopper frame and a mounting frame. A support plate is placed on the hopper frame. A lifting assembly is installed on the mounting frame, with a lifting plate at its front end. The lifting plate moves up and down via the lifting assembly. A displacement notch is provided at the rear end of the hopper frame to accommodate the vertical movement of the lifting plate, allowing the support plate to move up and down as well. Sheet material anti-sticking mechanisms are provided on both sides of the mounting frame, with the lower end of the anti-sticking mechanism higher than the upper end of the support plate. The main function of the anti-sticking mechanism is to increase friction between the sheet material and the sides of the stacked sheets. When the equipment picks up the top sheet material, the friction is greater than the suction force between the two sheets, making it easier for the top and bottom sheets to separate and open. In use, stacked sheets are placed on the support plate, and then the support plate and sheets are placed on the hopper rack for transfer. The rack is moved to the material handling station equipped with a lifting component, with the lifting plate positioned below the support plate. During the material handling process, the lifting component moves the lifting plate up and down, thereby moving the support plate on the hopper rack up and down. At the same time, during the material handling process of the corresponding equipment, the sheet anti-sticking mechanism set on the left and right sides of the mounting frame is used to stick to the stacked sheets on the support plate. The structure of this application allows the lifting plate and the support plate to move up and down via the lifting assembly on the mounting frame, thereby causing the stacked sheets on the support plate to move up and down, preventing the sheet material from being difficult to pick up due to a large height difference between the sheet material and the corresponding equipment. The displacement notch ensures that the lifting plate does not collide with the hopper frame when it moves the support plate up and down. At the same time, the sheet material anti-adhesion mechanism increases the friction between the sheet material and the side of the stacked sheet material, so that the sheet material on the top layer is separated from the sheet material below when it is picked up, preventing the two from sticking together and being picked up at the same time. Furthermore, the lower end of the sheet material anti-adhesion mechanism is higher than the upper end of the support plate, which can prevent it from colliding with the support plate and the hopper frame.

[0007] Furthermore, the lifting assembly includes two support frames disposed on the rear side of the mounting frame, with a lifting screw rotatably connected between the two support frames. One end of the lifting screw passes through the same support frame and is fixedly connected to the output end of the motor. A movable seat is threaded onto the lifting screw, and a connecting plate is disposed on the front side of the movable seat. A guide rail is disposed between the connecting plate and the mounting frame; the lifting plate is disposed on the front side of the connecting plate. This configuration allows the motor to drive the lifting screw to rotate, thereby causing the movable seat to move vertically in conjunction with the connecting plate and the guide rail; the guide rail provides a limit to prevent the movable seat from rotating along with it.

[0008] Furthermore, the lifting plate is provided with a positioning cone, and the material receiving plate is provided with a positioning cone hole that cooperates with the positioning cone. This arrangement allows for better positioning and limiting through the positioning cone and the positioning cone hole.

[0009] Furthermore, the sheet material anti-sticking mechanism includes a fixed frame mounted on a mounting bracket. A sliding assembly is located at the front end of the fixed frame, and a sliding plate is mounted on the sliding assembly. An adjusting screw is threaded onto the sliding plate, and an anti-sticking plate is rotatably connected to the inner end of the adjusting screw. A friction pad is located on the inner side of the anti-sticking plate, and a connecting guide rod is located on the outer side of the anti-sticking plate. The connecting guide rod is slidably connected to the sliding plate. The lower ends of the sliding plate, anti-sticking plate, and friction pad are higher than the upper end of the supporting plate. This configuration allows the sliding plate to move up and down at the front end of the fixed frame via the sliding assembly. The adjusting screw can be used to move the anti-sticking plate closer to or away from the stacked sheets. Furthermore, after the structure is in contact with the stacked sheets, when the lifting assembly moves the supporting plate up and down, the sliding assembly can also coordinate with the up and down movement, eliminating the need for repeated adjustments to the anti-sticking plate's position.

[0010] Furthermore, the sliding assembly includes a protruding strip disposed on the side of the sliding plate, a recessed block disposed at the front end of the fixing frame, and an anti-detachment block disposed on the upper end of the protruding strip; the protruding strip and the recessed block are slidably connected. The lower end of the protruding strip is higher than the upper end of the support plate. This configuration is simple in structure, allows the protruding strip to slide in cooperation with the recessed block, and limits the lowest position of the protruding strip and prevents it from falling off by the anti-detachment block.

[0011] Furthermore, the friction pad is made of rubber. Using rubber is cost-effective and allows for efficient separation of sheet materials.

[0012] Beneficial effects: The structure of this application enables the lifting plate and the support plate to move up and down through the lifting components on the mounting frame, thereby causing the stacked sheets on the support plate to move up and down, preventing the sheet material from being difficult to pick up due to a large height difference between the sheet material and the corresponding equipment; the setting of the displacement notch ensures that the lifting plate does not collide with the hopper frame when it moves the support plate up and down; at the same time, the sheet material anti-adhesion mechanism increases the friction between the sheet material and the side of the stacked sheet material, thereby separating the sheet material below from the top sheet material when it is picked up, preventing the two from sticking together and being picked up at the same time; and the lower end of the sheet material anti-adhesion mechanism is higher than the upper end of the support plate, which can prevent it from colliding with the support plate and the hopper frame.
