Description

Technical Field

[0001] This utility model relates to the field of 3C electronic technology, specifically a novel machine for stacking fiberglass back covers for mobile phones. Background Technology

[0002] As smartphones become thinner, lighter, and more high-performance, the requirements for the strength, toughness, and lightweight of materials for phone back covers are becoming increasingly stringent. Fiberglass boards, due to their high strength, low weight, and impact resistance, have become one of the core materials for mainstream phone back covers. The market demand for fiberglass boards for phone back covers continues to grow, and the requirements for their processing precision (such as dimensional deviation and interlayer bonding) and production efficiency are constantly increasing. Currently, the stacking processing of fiberglass boards for phone back covers is still mainly done manually.

[0003] Since the size of the fiberglass back cover of a mobile phone and its supporting leather and film is usually between a few centimeters and more than ten centimeters, and the interlayer bonding deviation needs to be controlled within a small range to meet the subsequent assembly requirements; manual operation relies on visual positioning and manual adjustment, and the positioning error is generally large, which can easily lead to interlayer misalignment. In subsequent assembly, secondary correction or even direct scrapping is required, which cannot adapt to the miniaturization of mobile phone components. Furthermore, manually completing processes such as feeding a single set of fiberglass boards, cutting the outer material, layering, and marking the positioning holes takes a long time.

[0004] To address this issue, we designed a new type of mobile phone back cover fiberglass board stacking machine. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of mobile phone back cover fiberglass board stacking machine to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a novel mobile phone back cover fiberglass board stacking machine, including a frame. Along the material conveying direction, the frame is sequentially equipped with a leather material feeding and cutting mechanism, a fiberglass feeding mechanism, a film laminating mechanism, a punching mechanism, a material pulling mechanism, and a finished product cutting mechanism. The fiberglass feeding mechanism includes at least two material bins arranged along the width of the frame. A fiberglass pushing component is provided below each material bin for pushing the mobile phone back cover fiberglass board in the bin to the laminating station of the film laminating mechanism. The leather material feeding and cutting mechanism is used to process the leather material... The machine performs fixed-length cutting and conveys the cut leather material to the lamination station; the film lamination mechanism is used to stack and press the fiberglass board pushed by the fiberglass feeding mechanism, the leather material conveyed by the leather material feeding and cutting mechanism, and the film to be laminated; the punching mechanism is used to punch positioning holes in the stacked material after lamination by the film lamination mechanism; the material pulling mechanism is used to drive the stacked material after punching positioning holes to move along the material conveying direction of the frame to achieve continuous feeding; the finished product cutting mechanism is used to cut the continuous stacked material conveyed by the material pulling mechanism into finished fiberglass back cover panels of preset size.

[0007] Furthermore, the fiberglass feeding mechanism has four hoppers arranged side by side, and each hopper is equipped with a material detection sensor for detecting the remaining amount of fiberglass board.

[0011] Furthermore, the punching mechanism includes a positioning table, guide posts, and punch assembly. The positioning table is fixed on the frame and has a positioning groove that matches the stacking contour of the fiberglass back cover of the mobile phone. The guide posts are vertically arranged at the four corners of the positioning table, and the punch assembly is slidably sleeved on the guide posts. The number of punches in the punch assembly is the same as the number of preset positioning holes in the stacking.

[0012] Furthermore, the material pulling mechanism includes a drive roller, a driven roller, and a drive motor. The output end of the drive motor is connected to the drive roller, and the driven roller is connected to the frame through an elastic bracket.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This utility model provides a technical solution: a novel mobile phone back cover fiberglass board stacking machine, including a frame, on which a leather material feeding and cutting mechanism 1, a fiberglass material feeding mechanism 6, a film laminating mechanism 2, a punching mechanism 3, a material pulling mechanism 4, and a finished product cutting mechanism 5 are sequentially arranged along the material conveying direction; the fiberglass material feeding mechanism 6 includes at least two material bins arranged along the width direction of the frame, and a fiberglass pushing component is provided below the material bins for pushing the mobile phone back cover fiberglass board in the material bins to the laminating station of the film laminating mechanism 2; the leather material feeding and cutting mechanism 1 is used to process the leather material... The machine performs fixed-length cutting and conveys the cut leather material to the lamination station; the film lamination mechanism 2 is used to stack and press the fiberglass board pushed by the fiberglass feeding mechanism 6, the leather material conveyed by the leather material feeding and cutting mechanism 1, and the film to be laminated; the punching mechanism 3 is used to punch positioning holes in the stacked material after lamination by the film lamination mechanism 2; the pulling mechanism 4 is used to drive the stacked material after punching positioning holes to move along the material conveying direction of the frame to achieve continuous feeding; the finished product cutting mechanism 5 is used to cut the continuous stacked material conveyed by the pulling mechanism 4 into finished mobile phone back cover fiberglass board products of preset size.

[0020] In practice, the following components are integrated sequentially along the material conveying direction: leather feeding and cutting mechanism 1, fiberglass feeding mechanism 6, film lamination mechanism 2, punching mechanism 3, material pulling mechanism 4, and finished product cutting mechanism 5. Each mechanism forms a workflow of leather cutting, fiberglass feeding, interlayer lamination, positioning punching, continuous material pulling, and finished product cutting through a preset conveying path. No manual material transfer is required, and the entire process of stacking fiberglass back cover panels for mobile phones is completed automatically. This setup can eliminate interlayer misalignment errors caused by manual transfer and is suitable for the miniaturization requirements of mobile phone components.

[0021] See Figure 1-3 The fiberglass feeding mechanism 6 has four hoppers arranged side by side, and each hopper is equipped with a material detection sensor to detect the remaining amount of fiberglass board.

[0022] In practice, the fiberglass feeding mechanism 6 has four parallel hoppers along the width of the frame, which can pre-store multiple sets of fiberglass back cover panels for mobile phones. The material detection sensor in each hopper monitors the remaining amount of fiberglass panels in real time. When the remaining amount is lower than the preset threshold, it automatically issues a replenishment prompt, eliminating the need for frequent manual checks on the hopper status.

[0023] See Figure 1-3 The fiberglass feeding mechanism 6 includes a fiberglass pushing component, which includes a pushing cylinder and a pushing plate. The fixed end of the pushing cylinder is connected to the frame, and the output end of the pushing cylinder is detachably connected to the pushing plate. The shape of the pushing plate is adapted to the outline of the discharge port of the hopper, and a flexible protective layer is provided on the side of the pushing plate facing the fiberglass board.

[0024] In practice, the fixed end of the push cylinder is connected to the frame, and the output end is detachably connected to the push plate. When feeding is required, the push cylinder drives the push plate to move horizontally and accurately pushes the fiberglass board in the hopper to the lamination station of the film lamination mechanism 2. A flexible protective layer is provided on the side of the push plate facing the fiberglass board to avoid scratching the surface of the fiberglass board during pushing.

[0025] See Figure 1-3 The leather feeding and cutting mechanism 1 includes an unwinding roller, a guide roller, a tension adjustment component, and a cutting component. The unwinding roller is used to place the rolled leather, the guide roller is used to guide the leather transmission direction, the tension adjustment component is used to adjust the tension during the leather transmission process, and the cutting trajectory of the cutting component is adapted to the preset shape of the mobile phone back cover leather.

[0026] In practice, the unwinding roller places the rolled leather material, which is then guided to the preset transmission path by the guide roller; the tension adjustment component adjusts the tension of the leather material to avoid wrinkles; the cutting component cuts the leather material to a fixed length according to the preset shape of the mobile phone back cover, and the cut material is directly conveyed to the lamination station of the film lamination mechanism 2.

[0027] See Figure 1-3 The film laminating mechanism 2 includes a pressing roller group arranged opposite each other. The pressing roller group includes an active pressing roller and a driven pressing roller. The active pressing roller is connected to the output end of the drive motor, and the surfaces of the active pressing roller and the driven pressing roller are covered with an elastic buffer layer.

[0028] In specific implementation, the pressing roller group of the film laminating mechanism 2 includes an active pressing roller and a driven pressing roller that are opposite each other: the active pressing roller is connected to the output end of the drive motor to provide pressing power; the driven pressing roller is connected to the frame through an elastic bracket, and the spacing can be adaptively adjusted according to the total thickness of the fiberglass board, leather and film; the surfaces of the active pressing roller and the driven pressing roller are covered with an elastic buffer layer, and when the stacked material passes between the two rollers, the elastic buffer layer applies uniform pressure.

[0029] See Figure 1-3 The punching mechanism 3 includes a positioning table, guide columns, and punch assembly. The positioning table is fixed on the frame and has a positioning groove that matches the stacking contour of the fiberglass back cover of the mobile phone. The guide columns are vertically set at the four corners of the positioning table. The punch assembly is slidably sleeved on the guide columns, and the number of punches in the punch assembly is the same as the number of preset positioning holes in the stacking.

[0030] In practice, the positioning table of the punching mechanism 3 is fixed on the frame, and the surface of the positioning table is provided with a positioning groove that is perfectly adapted to the outline of the fiberglass back cover of the mobile phone. The four corners of the positioning table are vertically provided with guide posts, and the punch assembly is slidably sleeved on the guide posts. The number of punches is consistent with the number of preset positioning holes in the stack. During punching, the punch moves down along the guide posts and punches positioning holes on the stack.

[0031] See Figure 1-3The material pulling mechanism 4 includes an active roller, a driven roller, and a drive motor. The output end of the drive motor is connected to the active roller, and the driven roller is connected to the frame through an elastic bracket. A transmission channel for clamping stacked materials is formed between the active roller and the driven roller, and the surfaces of the active roller and the driven roller are provided with anti-slip textures.

[0032] In practice, the output end of the drive motor of the material pulling mechanism 4 is connected to the active roller, which drives the active roller to rotate; the driven roller is connected to the frame through an elastic bracket, forming a clamping and transmission channel with the active roller; when the stacked material enters the channel, the anti-slip texture increases the friction to avoid slipping, and the active roller drives the driven roller to rotate synchronously, so as to stably transport the stacked material to the finished product cutting mechanism 5 along the transmission direction.

[0033] See Figure 1-3 The finished product cutting mechanism 5 has a finished product collection bin at its discharge end. The finished product collection bin is fixed on the frame and the inner wall of the finished product collection bin is lined with a cushioning pad.

[0034] In practice, the finished product cutting mechanism 5 cuts the continuously stacked materials into finished mobile phone back cover fiberglass boards of a preset size. The finished products slide down the discharge end to the finished product collection bin fixed on the frame. When the finished products fall, they come into contact with the buffer pad to avoid damage to the edges and corners caused by collision.

[0035] Working principle: The operator replenishes the mobile phone back cover fiberglass board to the four parallel material bins of the fiberglass feeding mechanism 6, and installs the rolled leather material onto the unwinding roller of the leather material feeding and cutting mechanism 1. First, the unwinding roller releases the leather material, which is then guided to a preset path by the guide roller. The tension adjustment component adjusts the tension in real time to prevent wrinkles, and the cutting component cuts the leather material to a preset shape and length. After cutting, the material is directly conveyed to the lamination station of the film lamination mechanism 2.

[0036] Simultaneously, the material detection sensor in the hopper monitors the remaining amount of fiberglass board and sends a replenishment prompt when it is insufficient; the push cylinder drives the push plate adapted to the hopper outlet to push the fiberglass board to the lamination station. The flexible protective layer of the push plate avoids scratching the fiberglass board. The four hoppers alternately supply material to ensure continuous production. Subsequently, the active pressure roller rotates under the drive of the drive motor, and the driven roller adjusts the spacing according to the total thickness of the fiberglass board, leather and film through the elastic bracket. The elastic buffer layer on the surface of the two rollers applies uniform pressure, and the laminated material is conveyed to the punching mechanism 3.

[0037] After the composite stacked material enters the punching mechanism 3, it falls into the matching positioning groove of the positioning table to achieve positioning. The four corner guide columns of the positioning table ensure the stability of the punch assembly trajectory. The punch punches positioning holes according to the preset number. After completion, the stacked material enters the pulling mechanism 4. In the material pulling mechanism 4, the drive motor drives the active roller to rotate, and the driven roller forms a clamping channel with the active roller through the elastic bracket. The anti-slip texture on the roller surface increases the friction and prevents slippage, so that the stacked material is conveyed to the finished product cutting mechanism 5 at a uniform speed. Finally, the finished product cutting mechanism 5 cuts the continuous stack of materials according to the preset size. The finished products slide down the discharge end to the collection bin with a buffer pad on the inner wall. The buffer pad prevents the corners of the finished products from being damaged by collision. When the bin is full, the system prompts to replace the bin. The entire process does not require manual transfer and realizes automated processing.
