Description

Technical Field

[0001] This utility model relates to the field of material feeding machine technology, specifically a material feeding device for automotive panel films. Background Technology

[0002] In the automotive interior film production field, the automotive panel film cutting device is a key automated equipment connecting the supply of film raw materials with subsequent fine processing. Its core function is to precisely cut, slit, or punch sheets of raw film according to the design dimensions and shape requirements of components such as automotive dashboards and center consoles, and then orderly transport the processed film products to the next process (such as punching, lamination, and inspection). It directly determines the efficiency and dimensional consistency of automotive interior film production and is a fundamental piece of equipment to ensure the quality of subsequent processing. In actual operation, existing automotive panel film cutting devices generally use electric suction cups as film transfer mechanisms. The electric suction cups adsorb the raw film materials or the cut film products and transfer them to a carrier plate for temporary storage or awaiting further processing. However, during the transfer and placement process, the film is often tilted or offset when placed on the carrier plate due to factors such as uneven suction force of the electric suction cup, easy deformation of the film itself, interference from small impurities on the carrier plate surface, or deviation in the alignment accuracy between the electric suction cup and the carrier plate. This causes the film to fail to align with the preset positioning reference of the carrier plate, which not only requires manual adjustment of the film position, increasing labor costs, but also affects the processing accuracy of subsequent punching, bonding and other processes due to the film position deviation. This can easily produce defective products with out-of-tolerance dimensions and excessive assembly gaps, making it difficult to meet the stringent requirements of automotive interior film for production efficiency and processing accuracy.

[0003] Therefore, this utility model provides an automotive panel film feeding device. Utility Model Content

The carrier plate has eight through holes and four U-shaped pushers. Each U-shaped pusher is slidably connected to the inner wall of two corresponding through holes and the bottom of the carrier plate. Threaded blocks are installed at the bottom of each of the four U-shaped pushers, and screws are threaded to the inner walls of each of the four threaded blocks. Driven gears are installed at opposite ends of each of the four screws, and driving gears mesh between the four driven gears. A drive unit, which is connected to the driving gear, is installed at the bottom of the carrier plate.

[0006] Preferably, each of the four U-shaped pushers has two arc-shaped surfaces on one side of its top end to facilitate the diaphragm falling into the area between the four U-shaped pushers.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-4 A device for feeding automotive panel films includes a movable support frame 1, a suction cup frame 11, a guide rail 12, and a material carrier plate 2. The material carrier plate 2 has eight through holes 21 and four U-shaped pusher frames 3. The U-shaped pusher frames 3 are slidably connected to the inner walls of two corresponding through holes 21 and the bottom of the material carrier plate 2. Each of the four U-shaped pusher frames 3 has a threaded block 31 installed at its bottom. Each of the four threaded blocks 31 has a screw 32 threadedly connected to its inner wall. Each of the four screws 32 has a driven gear 33 installed at one end opposite to the other. The four driven gears 33 are meshed with a drive gear 34. A drive unit 35 that is connected to the drive gear 34 is installed at the bottom of the material carrier plate 2.

[0022] Specifically, during operation, the movable support frame 1 moves along the guide rail 12, uses the suction cup frame 11 to pick up the membrane and transfer it above the carrier plate 2, at which point the membrane is positioned between the four U-shaped pusher frames 3. Next, the drive unit 35, a drive motor, starts, driving the drive gear 34 to rotate. Since the drive gear 34 meshes with the four driven gears 33, the four driven gears 33 rotate synchronously, thereby causing the screw 32, which is threadedly connected to it, to rotate. When the screw 32 rotates, the threaded block 31 moves along the screw 32, thereby causing the U-shaped pusher frames 3 to slide within the through hole 21. Four U-shaped pushers 3 move from the periphery towards the center, pushing and adjusting the placed film. The synchronized movement of the four U-shaped pushers 3 pushes any offset or tilted film to the center reference position of the carrier plate 2, achieving precise film positioning. During this process, the sliding of the U-shaped pushers 3 within the through holes 21 provides space for film placement and removal, facilitating the placement of the suction cup holder 11 and subsequent film removal. Furthermore, the single drive source 35 allows for synchronized control of the movement of the four U-shaped pushers 3, adapting to films of different sizes and offering strong versatility. This solves the problem of film tilting or shifting on the carrier plate due to uneven suction force of the electric suction cup and the inherent characteristics of the film itself. It eliminates the need for manual adjustments to the film position, reducing labor costs. Simultaneously, it ensures alignment of the film with the preset positioning reference of the carrier plate 2, improving the processing accuracy of subsequent punching and bonding processes, reducing the production of defective products, and meeting the stringent requirements for production efficiency and processing precision in automotive interior film manufacturing.

[0023] In one embodiment of this utility model, such as Figures 1-4 As shown, each of the four U-shaped pushers 3 has two arc-shaped surfaces 36 on one side of its top end, which facilitates the diaphragm falling into the area between the four U-shaped pushers 3.

[0024] Specifically, because the curved surface 36 has an inclined arc-shaped structure, even if there is a small deviation in the initial position during the descent, the diaphragm can slide into the area between the four U-shaped pushers 3 along the curvature of the curved surface 36. This avoids the diaphragm scraping or getting stuck with the right-angled edge of the top of the U-shaped pusher 3, allowing the diaphragm to fall more smoothly and quickly to the designated area, providing good preconditions for the subsequent precise pushing and adjustment of the diaphragm by the U-shaped pusher 3.

[0025] In one embodiment of this utility model, such as Figures 1-4 As shown, each of the four screws 32 has an end plate 321 installed at the far end, and the end plate 321 contacts the side wall of the corresponding threaded block 31.

[0026] Specifically, when the screw 32 rotates and drives the threaded block 31 to move along the screw 32, if the threaded block 31 moves to the end away from the screw 32, the end plate 321 will contact the side wall of the threaded block 31, preventing the threaded block 31 from continuing to move in that direction and preventing the threaded block 31 from disengaging from the screw 32. This ensures that the threaded connection between the threaded block 31 and the screw 32 is always stable and effective, thereby ensuring that the U-shaped pusher 3 can slide stably and reliably in the through hole 21 under the drive of the screw 32, realizing precise pushing and adjustment of the diaphragm, and ensuring the stable operation of the entire device for diaphragm positioning.

[0027] In one embodiment of this utility model, such as Figures 1-4 As shown, baffles 22 are slidably connected to the inner walls of the eight through holes 21, and the baffles 22 are in contact with the side walls of the corresponding U-shaped pusher frame 3.

[0028] Specifically, when the drive unit 35 moves the U-shaped pusher 3 towards the center to adjust the diaphragm position, the U-shaped pusher 3 can no longer move inward after contacting the baffle 22. At this point, the space between the four U-shaped pushers 3 matches the preset diaphragm specifications. In this way, the position of the baffle 22 can be adjusted in advance according to diaphragms of different sizes, so that the U-shaped pusher 3 can only clamp and position within the range of the corresponding diaphragm size. This ensures that the device is compatible with diaphragms of relatively large sizes, avoids diaphragm deformation due to excessive movement of the U-shaped pusher 3, and ensures that the positioning reference of diaphragms of the same specifications in different batches is consistent, thereby improving the positioning accuracy and adaptability of diaphragms of specific sizes.

[0029] In one embodiment of this utility model, such as Figures 1-4 As shown, each of the eight through holes 21 has an inner groove 211 on its inner wall. An electric telescopic rod 23 is installed on the inner wall of the inner groove 211, and one end of the electric telescopic rod 23 is fixed to the side wall of the baffle 22.

[0030] Specifically, when it is necessary to adapt to films of different sizes, the extension length of the electric telescopic rod 23 can be controlled to drive the baffle 22 to slide within the through hole 21, thereby quickly adjusting the position of the baffle 22 within the through hole 21. After the baffle 22 moves to a preset position that matches the target film size, the electric telescopic rod 23 remains fixed, so that the baffle 22 stably limits the movement range of the U-shaped pusher 3. This structure eliminates the need for manual adjustment of the baffle 22 position, achieving automated and precise adjustment of the baffle 22 position through electric drive. This not only improves the adjustment efficiency when switching between films of different sizes, but also ensures the positioning accuracy of the baffle 22, further guaranteeing the accuracy of the clamping and positioning of the U-shaped pusher 3 for films of different specifications, and meeting the processing needs of diverse sizes of automotive panel films.

[0031] In one embodiment of this utility model, such as Figures 1-4As shown, a support ring 4 is installed at the bottom of the material carrier plate 2, and four support blocks 41 are installed at the bottom end of the support ring 4. The screw 32 is rotatably connected to the inner wall of the corresponding support block 41.

[0032] Specifically, the screw 32 is rotatably connected to the inner wall of the corresponding support block 41, so that when the drive unit 35 drives the driving gear 34 and the driven gear 33 to rotate, the screw 32 can rotate stably with the support block 41 as a fixed fulcrum, avoiding wobbling or deviation of the screw 32 due to its own length or rotational force, and ensuring that the threaded transmission between the screw 32 and the threaded block 31 is always accurate and stable. At the same time, the combined structure of the support ring 4 and the support block 41 provides a reasonable distance between the transmission components such as the screw 32 and the driven gear 33 and the bottom of the material plate 2, which not only prevents interference between the transmission components and the material plate 2 or other structures when they are in operation, but also provides space for the installation and maintenance of each component, further ensuring the stable operation of the entire drive transmission system, thereby ensuring that the U-shaped pusher 3 can slide accurately under the drive of the screw 32 and achieve reliable positioning of the diaphragm.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] Working principle: When the automotive panel film feeding device is working, the movable support frame 1 moves along the guide rail 12, and the suction cup frame 11 adsorbs the film and transfers it to the top of the carrier plate 2. The film is guided by the arc surface 36 at the top of the U-shaped pusher frame 3, so that even if there is a small deviation in the initial position, it can fall smoothly between the four U-shaped pusher frames 3. After the drive unit 35 is started, it drives the drive gear 34 to rotate, which drives the four driven gears 33 to rotate synchronously through meshing, thereby causing the screw 32 to rotate. The screw 32 operates stably under the support of the support block 41 at the bottom of the support ring 4, avoiding shaking and deviation, and at the same time drives the screw connected to it. The threaded block 31 moves, and the end plate 321 at the end of the screw 32 prevents the threaded block 31 from disengaging. The threaded block 31 drives the U-shaped pusher 3 to slide along the through hole 21. According to the diaphragm size in advance, the baffle 22 is driven to move along the inner groove 211 to the preset position by the electric telescopic rod 23. The U-shaped pusher 3 stops after it contacts the baffle 22 and pushes the diaphragm to the center reference position of the carrier plate 2 from all sides, achieving precise positioning without manual adjustment. This solves the problem of diaphragm tilting and offset, ensures that the diaphragm is aligned with the positioning reference, improves the accuracy of subsequent processes, adapts to diaphragms of different sizes, and meets the requirements of production efficiency and accuracy.
