[0002] A film splicer is an automated device that can accurately bond protective film materials to designated objects. Existing automated film splicers can simultaneously complete tasks such as film material connection, continuous feeding, and film cutting. The feeding device is used to store film materials and continuously feed them to the film splicer.

[0003] Since the film material has a certain viscosity, different layers of film are easy to stick together when stacked on the storage table of the feeding device. Therefore, a separation blowing device is usually provided in the film feeding device. However, the existing separation blowing mechanism is generally arranged at the uppermost end of the storage table near the suction head to facilitate the separation of the stuck film material when the suction head grabs the film material. However, the blowing range of the blowing mechanism arranged near the suction head is fixed and single, and it cannot cooperate well with the storage table that can be raised and lowered for blowing and separation, which can easily lead to loss and deformation of the film material. Long-term operation may also lead to blockage or failure of the feeding device. [Utility Model Content]

[0014] The utility model also provides a film splicing machine, which includes the feeding device as mentioned above.

[0015] Compared with the prior art, the feeding device and film splicing machine provided by the utility model have the following advantages:

The lifting distance is transmitted to the lifting mechanism by the optical detection mechanism. The storage space can change its size according to the height movement of the lifting mechanism to store film materials of corresponding capacity. The blowing range of the blowing mechanism is located between 3 cm above and below the center line of the light sensing mechanism to effectively blow away the sticky film materials, avoid blockage and jamming of the film materials, and ensure smooth supply of the film materials.

[0017] 2.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0041] See also Figure 1-Figure 2 The solution to the technical problem solved by the present invention is to provide a feeding device 100, including a loading platform 1, baffles 2 arranged opposite to each other on the loading platform 1, and a lifting mechanism 3 connected to the loading platform 1, a storage space 4 is formed between the lifting mechanism 3 and the baffle 2, and the storage space 4 is used to store film material 8; a light sensing mechanism 5 is arranged on the two opposite baffles 2, and the light sensing mechanism 5 is arranged on the first side 21 of the baffle 2 facing the storage space 4, the feeding device 100 also includes a blowing mechanism 6 arranged corresponding to the light sensing mechanism 5, and the blowing mechanism 6 is arranged on the second side 22 adjacent to the first side 21, and the blowing range of the blowing mechanism 6 is located between 3 cm above and below the center line of the light sensing mechanism 5.

[0042] It can be understood that the light sensing mechanism 5 and the air blowing mechanism 6 work together to achieve precise management of the film material 8. The light sensing mechanism 5 can monitor the descent of the film material 8 in real time, ensure that the lifting mechanism 3 automatically adjusts the height, and always keeps the film material 8 in the optimal access position; the blowing range of the air blowing mechanism 6 is set between 3 cm above and below the center line of the light sensing mechanism 5, which can blow away the adhered film material 8, effectively avoid blockage or jamming of the film material 8, and ensure smooth supply of the film material 8.

[0043] Specifically, the loading platform 1 provides a flat platform for supporting and placing the entire feeding device 100. It is located at the bottom of the entire feeding device 100 and is connected to the jacking mechanism 3. The jacking mechanism 3 lifts the storage space 4 through a retractable support frame and is designed to be rectangular, circular or other shapes according to the needs of the feeding device 100.

[0044] The baffle 2 limits the flow range of the stored film material 8. The first embodiment of the present invention provides a feeding device 100 including at least six baffles 2, and more baffles 2 can be adaptively set according to the length of the film material 8. The number of baffles 2 is not specifically limited in the present invention.

[0045] The distance between the two opposing baffles 2 is set according to the width requirement of the film material 8. The two baffles 2 are arranged relative to each other to form an effective storage space, which together with the lifting mechanism 3 constitutes the storage space 4 for the film material 8 to prevent the film material 8 from scattering in the film supply device.

[0046] The opposite sides of the two baffles 2 are defined as the first side 21, and a light sensing mechanism 5 is provided on the first side 21. At the same time, the first side 21, as the side in direct contact with the film material 8, can be smoothed to a certain extent to prevent the film material 8 from being stuck during extraction. The baffle 2 and the lifting mechanism 3 are arranged on the same side of the loading platform 1 and are parallel to the lifting mechanism 3.

[0047] When needed, the lifting mechanism 3 raises the top height of the film material 8 to facilitate taking or lowers the top height of the film material 8 to increase the capacity of the storage space 4 to store more film material 8. The lifting mechanism 3 may include components such as a motor, a slide rail, and an electric or mechanically driven lifting device. The lifting mechanism 3 is directly connected to the loading platform 1 and is located on the center line relative to the two baffles 2.

[0048] Furthermore, the light sensing mechanism 5 is connected to the lifting mechanism 3 by signal. When the light sensing mechanism 5 senses that the top height of the film material 8 is lower than the height of the light sensing mechanism 5 , the lifting mechanism 3 pushes the lifting plate 41 to rise.

[0049] It can be understood that every time a film material 8 is taken away, the light sensing mechanism 5 can detect the drop of the top end of the film material 8 and transmit the signal to the lifting mechanism 3. The lifting mechanism 3 can rise to a height of the thickness of the film material 8, so that the top end of the film material 8 is always in a relative position level with the optical detection mechanism. The lifting distance is transmitted to the lifting mechanism 3 by the optical detection mechanism. The storage space 4 can change its size according to the height movement of the lifting mechanism 3 to store film materials 8 of corresponding capacity. The blowing range of the air blowing mechanism 6 is located between 3 cm above and below the center line of the light sensing mechanism 5 to effectively blow away the adhered film material 8, avoid blockage and jamming of the film material 8, and ensure smooth supply of the film material 8.

[0050] The signal fed back by the light sensing mechanism 5 provides the consumption status of the film material 8, improves the manageability of the film material 8, optimizes the storage and retrieval process, ensures the continuity of the film material 8 when picking up, shortens the travel distance of the upper material picking mechanism 7, and improves the efficiency of material picking.

[0051] Specifically, the light sensing mechanism 5 monitors the height changes of the film material 8 in real time and feeds back to the lifting mechanism 3, thereby driving the lifting and lowering of the lifting mechanism 3. The light sensing mechanism 5 includes components such as a light source and a photoelectric sensor, which are arranged on the first side 21 of the two opposite baffles 2 facing the storage space 4 to ensure that the film material 8 in the storage space 4 can be effectively sensed.

[0052] Furthermore, the film material 8 includes a first film material 81 located on the top layer and a second film material 82 adjacent to the first film material 81. The end of the first film material 81 close to the suction head 71 is defined as the first end 811. The suction head 71 extracts the first end 811 to the blowing range of the blower mechanism 6, and the first film material 81 and the second film material 82 are separated under the action of the blower mechanism 6.

[0053] It can be understood that since the surface of the film material 8 is relatively smooth, a certain amount of static electricity will be generated on the surfaces of the two adjacent first film materials 81 and the second film materials 82 when they are stacked and rubbed against each other. Under the action of electrostatic attraction and vacuum adsorption, the first film material 81 and the second film material 82 will stick together. When the first end 811 of the first film material 81 is adsorbed and lifted by the suction head 71, the second film material 82 will be lifted synchronously. The blowing mechanism 6 blows gas into the layers between the first film material 81 and the second film material 82. The film material 8 itself has a certain weight. The distance between the layers of the first film material 81 and the second film material 82 gradually increases under the action of wind. Due to the action of gravity, the second film material 82 automatically falls until the second film material 82 is completely separated from the first film material 81.

[0054] Specifically, the blowing mechanism 6 separates the first film material 81 on the top layer and the second film material 82 thereunder by accelerating the flow of air, effectively separating the layers of the film material 8 to prevent adhesion or accumulation. The blowing mechanism 6 includes an air source, an air duct, a nozzle and an airflow adjustment structure, which is located on the second side 22 adjacent to the first side 21. The nozzle faces the material storage space 4 to ensure that the airflow can blow directly to the layer between the first film material 81 and the second film material 82.

[0055] The blowing range of the hair dryer mechanism 6 is located 3 cm above and below the center line of the light sensing mechanism 5, that is, the position of the nozzle of the hair dryer mechanism 6 coincides with the center line of the light sensing mechanism 5. At the same time, the hair dryer mechanism 6 and the light sensing mechanism 5 are spaced apart, and a certain physical distance is maintained between the hair dryer mechanism 6 and the light sensing mechanism 5 to prevent the hair dryer mechanism 6 from interfering with the normal operation of the light sensing mechanism 5.

[0056] Furthermore, the air blowing mechanism 6 includes a first air blowing mechanism 61 , and the first air blowing mechanism 61 is arranged on the baffle 2 close to the side of the suction head 71 .

[0057] It can be understood that the first blowing mechanism 61 cooperates with the suction process and optimizes the taking and flow of the film material 8, more accurately separates the film material 8 that is about to undergo the next step, improves the separation efficiency, and enables the suction head 71 to stably and continuously take materials from the pile of film materials 8.

[0058] Furthermore, a lifting plate 41 is provided between the baffle 2 and the lifting mechanism 3 , and the lifting plate 41 is connected to the lifting mechanism 3 .

[0059] It can be understood that the lifting plate 41 is used to carry the stored film material 8, and the film material 8 is stacked on the lifting plate 41. The lifting plate 41 is connected to the lifting mechanism 3 to adjust the storage height of the film material 8, ensuring the accuracy of storage and retrieval of the film material 8.

[0060] Specifically, the lifting plate 41 is arranged in the storage space 4, serving as a carrier for the film material 8 in the storage space 4, supporting the weight of the film material 8. Optionally, the lifting surface can be made of a flat material or a non-slip material to ensure that the film material 8 does not slip during the stacking process;

[0061] The lifting plate 41 is connected to the lifting mechanism 3. An interface for connecting to the lifting mechanism 3 is provided on the lifting plate 41. The height of the top of the film material 8 can be accurately adjusted by adjusting the height in the vertical direction.

[0062] See also Figure 2 - Figure 3 Furthermore, the feeding device 100 also includes a material taking mechanism 7, which is arranged on one side of the storage space 4, and the material taking mechanism 7 includes at least two suction heads 71 ​​arranged in parallel.

[0063] It can be understood that at least two suction heads 71 ​​are set to balance the force during extraction, and each suction head 71 has an independent suction control mechanism, which effectively avoids the problem of unstable suction of the film material 8 by a single suction head 71, causing the film material 8 to fall, and avoids the situation where the material collection mechanism 7 cannot be used when a single suction head 71 fails.

[0064] Specifically, the material picking mechanism 7 also includes components such as a negative pressure air pipe, an air source, a driving device, a control device and an adjusting device. The driving device can control the vertical or horizontal movement of the suction head 71. The suction head 71 is soft and adaptable. The material picking mechanism 7 is also arranged on the side of the storage space 4 set on the loading platform 1, opposite to the entrance of the storage space 4, so that the material can be picked up smoothly when the film material 8 is accumulated.

[0065] Multiple suction heads 71 ​​are arranged in parallel, and the suction force is evenly distributed during the adsorption process, so that the film material 8 does not shift, deform or fall. The suction heads 71 ​​can adapt to film materials 8 of different shapes, weights and sizes. At least two suction heads 71 ​​are arranged side by side, and the distance between the two suction heads 71 ​​is adjusted according to the size and shape of the film material 8.

[0066] Furthermore, the suction head 71 is arranged perpendicular to the length direction of the storage space 4 , and the suction head 71 can move relative to the loading platform 1 in two directions: perpendicular and parallel to the loading platform 1 .

[0067] It can be understood that the suction head 71 moves in both vertical and parallel directions, and the suction head 71 can more accurately locate the film material 8 at the top of the storage space 4, thereby improving the efficiency of the feeding device 100 in extracting, transporting and storing the film material 8.

[0068] Furthermore, the feeding device 100 further includes a frame 72 , and the material taking mechanism 7 is mounted on the frame 72 . The frame 72 pulls the material taking mechanism 7 to move relative to the loading platform 1 in two directions, vertical and parallel to the loading platform 1 .

[0069] It can be understood that the frame 72 is a carrier of physical support, providing movement guidance and support for the suction head 71, bearing the load of the material taking mechanism 7, and ensuring the stability of the entire feeding device 100.

[0070] Furthermore, the feeding device 100 further includes a pressure sensing mechanism 73 , and the pressure sensing mechanism 73 is electrically connected to at least one suction head 71 .

[0071] It can be understood that the pressure sensing mechanism 73 enables the suction head 71 to absorb the stacked film material 8 layer by layer, and does not cause excessive gripping force when gripping the film material 8, resulting in gripping of multiple layers of film material 8.

[0072] The blowing working state of the blower mechanism 6 is associated with the pressure sensing mechanism 73. When the suction head 71 absorbs the film material 8, the pressure sensing mechanism 73 monitors the change of suction force in real time and works synchronously with the blower mechanism 6 to ensure that the suction head 71 does not absorb multiple layers of film material 8: the pressure sensing mechanism 73 transmits a feedback signal to the blower mechanism 6. When the pressure change detected by the pressure sensing mechanism 73 exceeds the preset pressure value of a piece of film material 8, the blower mechanism 6 will increase the airflow or perform a sweeping motion to expand the blowing range to help separate the first film material 81 from the second film material 82, and prevent the suction head 71 from extracting multiple layers of film material 8.

[0073] See also Figure 4 The second embodiment of the present invention provides a film splicing machine 200, which includes a feeding device 100 as provided in the first embodiment. The film splicing machine 200 has the same beneficial effects as the feeding device 100, which will not be described in detail here.

[0074] The film splicing machine 200 further includes a conveying device, which is docked with the feeding device 100 , and the suction head 71 accurately transfers the film material 8 to the film splicing area of ​​the conveying device to complete the subsequent operation of the film splicing machine 200 .

[0075] Compared with the prior art, the feeding device and film splicing machine provided by the utility model have the following advantages:

[0076] 1. The feeding device provided in the embodiment of the present invention, whenever a film material is taken away, the light sensing mechanism can detect the drop of the top end of the film material, and the lifting mechanism can rise to a height of the thickness of the film material, so that the top end of the film material is always in a relative position level with the optical detection mechanism. The lifting distance is transmitted to the lifting mechanism by the optical detection mechanism. The storage space can change its size according to the height movement of the lifting mechanism to store film materials of corresponding capacity. The blowing range of the blowing mechanism is located between 3 cm above and below the center line of the light sensing mechanism to effectively blow away the sticky film materials, avoid blockage and jamming of the film materials, and ensure smooth supply of the film materials.

[0077] 2. In the feeding device provided in the embodiment of the present invention, the lifting plate is used to carry the stored film material, and the film material layers are stacked on the lifting plate. The lifting plate is connected to the lifting mechanism to adjust the film material storage height, thereby ensuring the accuracy of film material storage and retrieval.

[0078] 3. The feeding device provided in the embodiment of the present invention has a lifting mechanism that automatically adjusts the storage space according to the feedback signal of the light sensing mechanism so that the height of the top of the film material is always maintained at the same height as the light sensing mechanism. The signal feedback from the light sensing mechanism provides information on the consumption of the film material, thereby improving the manageability of the film material, optimizing the storage and retrieval process, ensuring the continuity of the film material picking up, shortening the travel distance of the upper material picking mechanism, and improving the efficiency of material picking.

[0079] 4. The feeding device provided in the embodiment of the present invention is provided with at least two suction heads to balance the force during extraction, effectively avoiding the problem of unstable suction of the film material by a single suction head causing the film material to fall, and avoiding the situation where the material taking mechanism cannot be used when a single suction head fails.

[0080] 5.

[0081] 6. The feeding device provided in the embodiment of the present invention has a suction head that moves in both vertical and parallel directions. The suction head can more accurately locate the film material at the top of the storage space, thereby improving the efficiency of the feeding device in extracting, transporting and storing the film material.

[0083] 8. The feeding device provided in the embodiment of the present invention has a pressure sensing mechanism that enables the suction head to absorb the stacked film material layer by layer, so that when grabbing the film material, there is no excessive gripping force that may result in grabbing multiple layers of film material.

[0084] 9. The feeding device provided in the embodiment of the present invention has a relatively smooth surface of the film material. When the two adjacent first film materials and the second film material are stacked and rubbed against each other, a certain amount of static electricity will be generated on the surface. Under the action of electrostatic attraction and vacuum adsorption, the first film material and the second film material will stick together. When the first end of the first film material is adsorbed and lifted by the suction head, the second film material will be lifted synchronously. The blowing mechanism blows gas into the layers between the first film material and the second film material. The film material itself has a certain weight. The layers gradually increase under the action of wind, and the second film material is completely separated from the first film material.

[0085] 10. The present invention also provides a film splicer, which has the same beneficial effects as the feeding device and will not be described in detail here.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.
