Description

Technical Field

[0001] This utility model relates to a die-cutting device, and more particularly to a precision die-cutting device for photosensitive dry film. Background Technology

[0002] Precision die-cutting equipment for photosensitive dry films is mainly used for high-precision cutting and shaping of photosensitive dry films. This equipment can ensure that the photosensitive dry film can meet the production requirements of customers in subsequent related production processes such as exposure, development and etching, according to customer needs.

[0003] Die-cutting is a process used to precisely cut photosensitive dry film into a predetermined shape and size. This process not only ensures aesthetics and functionality but also improves the efficiency of subsequent processing steps and reduces material waste. It is a key step in ensuring the stable performance of the final product. In existing die-cutting technologies, film material tends to stick to the die during die-cutting. This prevents the film material from completely detaching from the die, thus affecting the accuracy and quality of die-cutting. Film material residue not only reduces the yield rate of products but also increases the frequency of manual die cleaning during production, prolongs the production cycle, and increases production costs, seriously affecting production efficiency and economic benefits. Utility Model Content

[0004] To overcome the problem of film material sticking to the die during die cutting, which prevents the film material from completely detaching from the die and thus affects the precision and quality of die cutting, the purpose is to provide a precision die cutting device for photosensitive dry film that can remove residual waste material from the die during die cutting.

[0005] The technical solution of this utility model is as follows: a precision die-cutting device for photosensitive dry film, comprising a device body, a pressure table, an upper die, a worktable, a lower die, a cross slide, a transmission group one, a transmission group two, a slider, an air valve, an air pipe, and an air blowing nozzle. The device body has a processing cavity. A stamping lifting component is located in the upper part of the device body, and a worktable is located in the lower part of the device body. A lower die is located on the worktable. A pressure table is slidably located in the upper part of the device body. The pressure table is driven by the stamping lifting component to move up and down within the device body. An upper die is located on the upper part of the pressure table. When the upper die is pressed down by the pressure table, it contacts the lower die. The upper and lower dies work together to achieve die-cutting of the photosensitive film through precise alignment and high-pressure stamping. A cross slide is located on one side of the processing cavity of the device body. The cross slide is driven by a transmission... The system consists of a first group and a second transmission group. The movement trajectories of the first and second transmission groups are intersecting in a cross shape. The second transmission group is equipped with a slider, which moves up and down vertically on the second transmission group. This design enables precise movement of the slider in both horizontal and vertical directions. The slider is equipped with an air valve, and an air connector is located on one side of the air valve. Two air pipes are connected to the air valve, and multiple air nozzles are arranged at intervals on each air pipe. The two air pipes are arranged vertically on the air valve, and the air nozzles on the two air pipes are symmetrically arranged. The air outlets of the air nozzles are inclined and face the upper and lower sides of the rear respectively. When the upper and lower molds separate, there is a gap between the upper and lower molds. Driven by the cross slide, the air pipes on the slider move back and forth within the gap area between the upper and lower molds.

[0006] As a preferred technical solution of this utility model, it also includes a rotating frame and a cleaning roller. The rotating frame is symmetrically and rotatably arranged on the side of the slider away from the air valve. Each rotating frame is composed of a rotating roller and two connecting blocks. The rotating frame is arranged in the same direction as the air pipe. The cleaning roller is rotatably arranged between the connecting blocks of the rotating frame.

[0007] As a preferred technical solution of this utility model, it also includes an electric cylinder, gears and racks. The rotating roller of the rotating frame is provided with gears, and two gears mesh with each other. An electric cylinder is provided on the upper part of the slider. A rack is provided on the drive rod of the electric cylinder. The rack meshes with a gear. When the drive rod of the electric cylinder extends and retracts, the rack moves, thereby driving a gear in contact with the rack to rotate. Under the meshing of the gears, the two gears rotate synchronously in opposite directions, driving the two rotating frames to rotate, thereby driving the cleaning roller to synchronously realize the up and down arc swing.

[0008] As a preferred technical solution of this utility model, it also includes a material transfer frame, an air outlet, an air box, an air outlet hole, and a guide plate. The material transfer frame is provided in the rear part of the equipment body. The material transfer frame is arranged through the front and rear. An air outlet is provided in the rear part. An air box is symmetrically arranged above and below the air outlet of the rear part of the material transfer frame. An air connector is provided on one side of the air box. Several air supply branches are provided on each air box. Multiple air outlet holes are opened on the upper and lower sides of the air outlet of the rear part of the material transfer frame. Each air supply branch pipe passes through one air outlet hole. Guide plates are symmetrically arranged above and below the rear part of the material transfer frame. The guide plates are arranged in an inclined shape. After the air in the air box passes through the air supply branch pipe, it is discharged from the air outlet hole into the air outlet of the material transfer frame and impacts a nearby guide plate. Under the guidance of the guide plate, the air flow rushes backward.

[0009] As a preferred technical solution of this utility model, it also includes a material collection frame and a feed inlet. The material collection frame is provided at the rear of the equipment body. The inside of the material collection frame is hollow. A feed inlet is opened on the upper front side, and a discharge outlet is provided at the lower part. The feed inlet of the material collection frame is directly opposite the air outlet of the material transfer frame.

[0010] Beneficial effects: This utility model sets a cross slide on the main body of the equipment and sets two sets of air blowing nozzles on the slider of the cross slide. Before and after die cutting, the air blowing nozzles are driven by the cross slide to move back and forth between the upper and lower dies to clean the residual photosensitive film material on the upper and lower dies. The airflow thoroughly removes the tiny particles and debris remaining on the mold surface, ensuring that the mold surface is clean and tidy, thereby improving the accuracy of subsequent die cutting and the yield of products.

[0011] This invention utilizes an adjustable cleaning roller mounted on a slider, which makes close contact with the mold surface, enabling physical cleaning of the mold before and after die-cutting to remove surface dust and residue. Simultaneously, an air blowing device further removes tiny particles and debris from the mold surface, ensuring a clean and residue-free finish. This dual-cleaning method not only improves mold cleaning efficiency but also effectively extends mold lifespan, thereby enhancing overall production quality and efficiency.

[0012] This invention, through the design of suction and recovery components, can effectively gather and collect the airflow carrying film material blown out by the air nozzle, preventing the film material from scattering inside the equipment or in the surrounding environment, reducing cleaning workload, and also preventing environmental pollution in the workshop caused by flying fine particles.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0022] Example 1

[0023] The equipment body 1 has a processing cavity inside. The design of the processing cavity provides sufficient space for the entire die-cutting process, ensuring the smooth operation of each component, and also facilitating maintenance and inspection. The upper part of the equipment body 1 is equipped with a stamping lifting component, which is responsible for driving the upper die to move up and down. By precisely controlling the descent speed and force of the upper die, the accuracy and consistency of the die-cutting process are ensured. The lower part of the equipment body 1 is equipped with a worktable 3, on which a lower die 31 is mounted. The design of the worktable 3 and the lower die 31 ensures the stable placement of the photosensitive film, providing a stable foundation for subsequent die-cutting operations. The precise cooperation between the lower die 31 and the upper die ensures that the photosensitive film is subjected to uniform pressure during the die-cutting process, avoiding product quality problems caused by uneven pressure, and improving the product qualification rate and production efficiency.

[0024] The upper part of the equipment body 1 is equipped with a sliding pressure table 2. The pressure table 2 is driven by a stamping lifting component and moves up and down within the equipment body 1. The design of the pressure table 2 allows it to move smoothly within the equipment body 1, reducing friction during the movement. The upper part of the pressure table 2 is equipped with an upper mold 21. When the upper mold 2 is pressed down with the pressure table 2, it will contact the lower mold 31. The connection structure between the upper mold 21 and the pressure table 2 is stable, ensuring the positional accuracy of the upper mold 21 during the pressing process, while avoiding the offset during the die-cutting process. The upper and lower molds work together to achieve the die-cutting of the photosensitive film through precise alignment and high-pressure stamping.

[0025] A cross slide 4 is provided on one side of the processing cavity of the equipment body 1. The cross slide 4 consists of a first transmission group 41 and a second transmission group 42. The movement trajectories of the first transmission group 41 and the second transmission group 42 intersect in a cross shape. A slider 5 is provided on the second transmission group 42. The slider 5 moves up and down vertically on the second transmission group 42. Through this design, precise movement of the slider 5 in both horizontal and vertical directions is achieved. The multi-dimensional precise movement of the slider 5 enables the cleaning components installed on it to accurately reach the designated positions, improving cleaning efficiency and effectiveness.

[0026] The slider 5 is equipped with an air valve 51, and an air connector is provided on one side of the air valve 51. Two air pipes 52 are connected to the air valve 51. Multiple air nozzles 53 are arranged at intervals on each air pipe 52. The two air pipes 52 are arranged vertically on the air valve 51, and the air nozzles 53 on the two air pipes 52 are symmetrically arranged. The air outlets of the air nozzles 53 are inclined to the upper and lower sides of the rear. The airflow in the air nozzles 53 of the upper and lower air pipes 52 will blow onto the surfaces of the upper mold 21 and the lower mold 31 respectively. The air connector on the air valve 51 is used to connect to a high-pressure air source. The airflow is transmitted to the air pipes 52 through the air valve, ensuring a stable airflow supply. The purpose of the inclined rearward arrangement of the air nozzles 53 is that, during cleaning, the air pipes are moved from front to back by the cross slide 4, so that the blown airflow and the film material carried by the airflow can be blown out of the equipment, effectively removing the residue generated during the die-cutting process, reducing the contamination of the mold surface, and not affecting the personnel in front of the equipment.

[0027] When the upper mold 21 and the lower mold 31 separate, there is a gap between the upper mold 21 and the lower mold 31. Under the drive of the cross slide table 4, the air pipe 52 on the slider 5 moves back and forth in the gap area between the upper mold 21 and the lower mold 31. Through this design, not only can the mold surface be pre-cleaned before die cutting to ensure the smooth progress of the die cutting process, but also the residue can be removed immediately after die cutting to keep the mold clean, extend the service life of the mold, and improve production efficiency and product quality.

[0028] Example 2

[0029] Based on Example 1, such as Figure 3and Figure 4 As shown, it also includes a rotating frame 6 and a cleaning roller 61. The rotating frame 6 is symmetrically and rotatably mounted on the side of the slider 5 away from the air valve 51. Each rotating frame 6 consists of a rotating roller and two connecting blocks. The rotating frame 6 is arranged in the same direction as the air pipe 52. Cleaning rollers 61 are rotatably mounted between the connecting blocks of the rotating frame 6. The design of the cleaning roller 61 allows it to make close contact with the mold surface during the movement of the slider 5, effectively removing dust and residue from the mold surface and improving the cleaning effect.

[0030] Among them, such as Figure 3 and Figure 4 As shown, it also includes an electric cylinder 62, a gear 63, and a rack 64. The rotating roller of the rotating frame 6 is equipped with a gear 63, and two gears 63 mesh with each other. The upper part of the slider 5 is equipped with an electric cylinder 62, and the drive rod of the electric cylinder 62 is equipped with a rack 64. The rack 64 meshes with one of the gears 63. When the drive rod of the electric cylinder 62 extends or retracts, the rack 64 moves, thereby driving the gear 63 in contact with the rack 64 to rotate. The rotation of the gear 63 is transmitted to the other gear 63 through the meshing relationship, so that the two gears 63 rotate synchronously in opposite directions, driving the two rotating frames 6 to rotate, and thus driving the cleaning roller 61 to synchronously swing up and down in an arc. This design not only allows the cleaning roller 61 to cover a larger cleaning area, but also allows for flexible adjustment according to the specific conditions of the mold surface, improving the flexibility and adaptability of cleaning.

[0031] In summary, by setting an adjustable cleaning roller 61 on the slider 5 to make close contact with the mold surface, the mold can be physically cleaned before and after die cutting to remove dust and residues from the surface. At the same time, in conjunction with the air blowing device, the airflow further removes tiny particles and debris from the mold surface, ensuring that the mold surface is clean and free of residues. This dual cleaning method not only improves the cleaning efficiency of the mold, but also effectively extends the service life of the mold, thereby improving the overall production quality and efficiency.

[0032] Among them, such as Figure 5 and Figure 6As shown, the device also includes a material transfer frame 7, an air outlet 70, an air box 71, an air outlet 710, and a guide plate 72. The material transfer frame 7 is located at the rear of the device body 1. The material transfer frame 7 is arranged through the entire device, and an air outlet 70 is located at its rear. The design of the material transfer frame 7 ensures that the airflow can pass smoothly and avoids airflow blockage during transmission. The air boxes 71 are symmetrically arranged above and below the air outlet 70 at the rear of the material transfer frame 7. An air connector is provided on one side of the air box 71. Each air box 71 is equipped with several air supply branches. The design of the air box 71 can store and distribute airflow to ensure a stable airflow supply. Multiple air outlets 710 are opened on both the upper and lower sides of the air outlet 70 at the rear of the material transfer frame 7. Each air vent pipe passes through one air outlet 710. The design of the air outlets 710 allows the airflow to be evenly distributed, improving the coverage and impact force of the airflow. The rear of the material transfer frame 7 is symmetrically equipped with guide plates 72. The guide plates 72 are set at an angle. The design of the guide plates 72 can guide the direction of the airflow, making it more concentrated and powerful. The airflow in the air box 71 passes through the air vent pipe and is discharged from the air outlet 710 into the air outlet 70 of the material transfer frame 7, and impacts a nearby guide plate 72. Under the guidance of the guide plate 72, the airflow rushes backward. This design not only enhances the impact force of the airflow, but also ensures that the airflow can effectively cover the air outlet 70 area of ​​the material transfer frame 7, driving the airflow in the equipment body 1 to flow from front to back. This airflow will pass through the rear interior of the material transfer frame 7 from front to back and be transmitted backward. It should also be noted that the airflow inside the air box begins to blow out when the air tube 52 moves, and stops after the air tube 52 returns to its original position for a period of time. It does not blow out continuously. It works in coordination with the movement of the air tube 52 to reduce energy waste.

[0033] like Figure 5 and Figure 7 As shown, the equipment also includes a collection frame 8 and a feed inlet 81. The collection frame 8 is located at the rear of the equipment body 1. The collection frame 8 is hollow inside, with a feed inlet 81 on the upper front side and a discharge outlet at the lower part. The feed inlet 81 of the collection frame 8 is directly opposite the air outlet 70 of the transfer frame 7. The design of the collection frame 8 can effectively collect the airflow containing film material discharged from the air outlet 70 of the transfer frame 7, preventing the film material from scattering inside the equipment or in the surrounding environment, reducing the amount of cleaning work, and also preventing the pollution of the workshop environment caused by flying fine particles. Through the collection of the collection frame 8 and the discharge of the discharge outlet, the collected film material can be centrally processed, improving the resource recycling rate and reducing production costs. This integrated suction and recycling design not only improves the overall performance of the equipment, but also improves the working environment of the workshop.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
