Description

Technical Field

[0001] This utility model relates to a composite material cutting machine, specifically to a vacuum adsorption plate and a composite material cutting machine. Background Technology

[0002] Composite material cutting machines are primarily designed for CNC cutting of flexible materials such as carbon fiber, glass fiber, soft glass, EVA foam, and honeycomb profiles. They utilize a vacuum adsorption plate to adsorb and position the flexible material, allowing a laser cutting head or vibrating knife cutting head to cut it. For example, Chinese Patent 201920623408.2 discloses a flexible material CNC vibrating knife cutting machine with vacuum adsorption function, comprising: a machine tool body, an X-axis, a Y-axis, and a Z-axis; the Y-axis is fixedly mounted on the machine tool body; the X-axis is slidably mounted on the Y-axis above the machine tool body; and the Z-axis is slidably mounted on the X-axis above the machine tool body for cutting flexible products. The machine tool body includes: a frame, a vacuum adsorption table, a vacuum adsorption mechanism, and sheet metal parts mounted on the outer surface of the frame.

[0003] The existing technology has the following drawbacks: In the vacuum adsorption of flexible materials in a single zone of a vacuum adsorption stage, the suction force is stable in the area near the negative pressure suction end of the stage, while the suction force is weak in the area far from the negative pressure suction end. The uneven distribution of suction force can easily lead to insufficient adsorption force in local areas (far from the negative pressure suction end) during cutting, resulting in displacement of the flexible composite material during processing and affecting the cutting quality. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a vacuum adsorption plate to solve the technical problem of uneven suction distribution and insufficient adsorption force in local areas during cutting in the prior art.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, this utility model provides a vacuum adsorption plate, comprising: A base, wherein a plurality of partitioned frames are provided on the base, and guide grooves are arranged on the partitioned frames; An adsorption panel is located on the top of the base. The adsorption panel has several pairs of partition adsorption holes located in the partition frame and several pairs of positioning adsorption holes located in the guide groove. The partitioned adsorption pipeline is located at the bottom of the base and has partitioned suction ends that correspond one-to-one with and communicate with the partitioned frames. Each partitioned suction end is equipped with an on / off component for switching on and off. The positioning adsorption pipeline is located at the bottom of the base and has a positioning suction end that communicates with the guide channel.

[0006] In some embodiments, the partitioned adsorption pipeline includes a main pipeline, a first branch pipeline, and a second branch pipeline. One end of the main pipeline is connected to a plurality of first branch pipelines, and one end of the first branch pipeline away from the main pipeline is connected to a plurality of second branch pipelines. The one end of the second branch pipeline away from the main pipeline is connected and communicates with each partitioned frame in a corresponding manner.

[0007] In some embodiments, the end of the first branch pipe away from the main branch pipe is further provided with a secondary main branch pipe extending to the outside of the base.

[0008] In some embodiments, the number of partition frames is eight, arranged in an octagonal grid on the base.

[0009] In some embodiments, the guide channel includes at least one first linear channel extending along the length of the base and at least two second linear channels extending along the width of the base, forming at least two cross-shaped channels.

[0010] In some embodiments, the positioning adsorption pipeline includes a suction pipeline and several branch pipelines, one end of each of the branch pipelines being connected to the suction pipeline, and the other end of each branch pipeline being connected and communicated with the center of the cross groove.

[0013] In some embodiments, the inner bottom wall of the partition frame is provided with a flow guiding mesh groove.

[0014] Secondly, this utility model also provides a composite material cutting machine, including a vacuum adsorption plate as described in any of the above.

[0015] Compared with the prior art, the vacuum adsorption plate provided by this utility model forms a vacuum adsorption platform with partitioned frames on the base, each corresponding to an adsorption hole in the partition.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem of uneven suction distribution and insufficient localized suction during cutting, this invention provides a vacuum adsorption plate. The plate utilizes partitioned frames 101 on a base 1 to create a vacuum adsorption platform, with each partition having its own adsorption hole 201. By switching the negative pressure suction on and off in the partitioned adsorption pipes 3, the negative pressure suction is directed to the cutting position, concentrating the adsorption area at the cutting location and improving adsorption stability. Furthermore, the guide channel 102 and positioning adsorption pipes 4 provide a separate negative pressure channel for the positioning adsorption hole 202 area, enabling continuous vacuum adsorption of the composite material and ensuring consistent positioning. This avoids the displacement effects of suction fluctuations during partition switching on the composite material.

[0020] It should be noted that the vacuum adsorption plate described in this utility model is used in, but not limited to, composite material cutting machines. For ease of explanation, this utility model only uses the application of the vacuum adsorption plate in a composite material cutting machine as an example. The principle of the vacuum adsorption plate in other types of equipment is essentially the same as that in the composite material cutting machine, and will not be described in detail here.

[0021] Please see Figure 1-4 This utility model provides a vacuum adsorption plate, which includes a base 1, an adsorption panel 2, partitioned adsorption pipes 3, and positioning adsorption pipes 4. The base 1 has multiple partitioned frames 101 arranged in an array along the length of the base 1. Preferably, there are eight partitioned frames 101 arranged in an octagonal grid on the base 1, which evenly divides the adsorption area into two symmetrical sections. Each section has four partitioned frames 101, resulting in a total of eight sections within the two sections, i.e., an octagonal grid layout. The base 1 has guide channels 102 arranged on the dividing lines of the partitioned frames 101. The guide channels 102 must at least substantially cover the adsorption area along the length direction; that is, the guide channels 102 include at least one first linear channel 102a extending along the length of the base 1, thus providing adsorption and positioning for carbon fibers arbitrarily placed in the length direction. Correspondingly, in order to match the partition frame 101 and the guide channel 102 to form an adsorption positioning on the top surface of the adsorption plate, an adsorption panel 2 is fixedly connected to the top of the base 1. The adsorption panel 2 is located on the top of the base 1. The adsorption panel 2 has a plurality of pairs of partition adsorption holes 201 located in the partition frame 101 and a plurality of pairs of positioning adsorption holes 202 located in the guide channel 102. The partition adsorption holes 201 are connected to the internal passage of the corresponding partition frame 101, and the positioning adsorption holes 202 are connected to the guide channel 102. The partitioned adsorption pipeline 3 is located at the bottom of the base 1 and has partitioned suction ends 301 that correspond one-to-one with and are connected to the partitioned frames 101. Each partitioned suction end 301 is equipped with an on / off component 302 for switching on and off. The partitioned adsorption pipeline 3 is used to connect to a vacuum pump to create a vacuum at the partitioned suction end 301. In the connected state, negative pressure suction can be generated in the partitioned adsorption holes 201 of the corresponding partition to adsorb and position the composite material. The positioning adsorption pipeline 4 is located at the bottom of the base 1 and has a positioning suction end 401 that is connected to the guide groove 102. The positioning adsorption pipeline 4 is used to connect to a vacuum pump. It is connected to a separate vacuum pump that is different from the vacuum pump connected to the partitioned adsorption pipeline 3 to form an independent vacuum path. Negative pressure is created in the positioning adsorption hole 202 to adsorb and position the composite material.

[0022] In this embodiment, the system employs zoned adsorption and allows for the installation of multiple fans along the expansion path, facilitating the expansion or replacement of negative pressure fans based on the actual required negative pressure intensity. With a zoned arrangement, the corresponding zones are connected according to the cutting position, resulting in a concentrated distribution of suction force. This reduces the area requiring negative pressure extraction, and the concentrated distribution ensures relatively uniform suction force and more stable adsorption. The guide channels 102, positioned at the zone boundaries, form a buffer adsorption area for zone switching, providing continuous adsorption stability. By targeting the cutting position with specific zones, the buffer adsorption area formed by the guide channels 102 provides stable adsorption during zone switching, reducing potential fluctuations in material positioning and adsorption.

[0023] In one embodiment, please refer to Figure 2 and Figure 4 To balance the path length of negative pressure suction to each zone, the partitioned adsorption pipeline 3 includes a main pipeline 31, a first branch pipeline 32, and a second branch pipeline 33. The end of the main pipeline 31 is connected to the two first branch pipelines 32. The main pipeline 31 is located at the midpoint of the base 1 and extends laterally to the outside of the base 1 for connecting to the vacuum pump pipeline. The end of the first branch pipeline 32 away from the main pipeline 31 is connected to the four second branch pipelines 33. The end of the first branch pipeline 32 away from the main pipeline 31 is located at the geometric center of the four partitioned frames 101. The four second branch pipelines 33 are distributed circumferentially around this geometric center and extend to the center point of the four partitioned frames 101. The ends of the second branch pipelines 33 away from the main pipeline 31 are connected and communicated with the partitioned frames 101 one by one.

[0024] This is understandable; please refer to [link / reference]. Figure 4 With the arrangement of the main pipeline 31, the first branch pipeline 32 and the second branch pipeline 33, the paths from the main pipeline 31 to each zone suction end 301 are all equal, making the suction of each zone suction end 301 more uniform and reducing the possible negative pressure difference.

[0025] For further details, please refer to Figure 4 To facilitate the expansion of the number of vacuum pumps, a secondary main pipeline 34 extending to the outside of the base 1 is provided at the end of the first branch pipe away from the main pipeline 31. When one vacuum pump is connected to the main pipeline 31, it can provide suction negative pressure for the vacuum pump; when two branch main pipelines 31 are used separately, two vacuum pumps can be connected to provide independent negative pressure suction for both plates. By switching the on and off of each zone as needed, a better adsorption effect can be obtained.

[0026] Understandably, when using one vacuum pump, the other two secondary main pipelines 34 are sealed with plugs, and when using two vacuum pumps, the main pipeline 31 is sealed with plugs.

[0027] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 In order to extend in the width direction on the basis of covering along the length direction and provide a stable coverage range, the guide groove 102 includes at least one first linear groove 102a that runs through the base 1 along the length direction and at least two second linear grooves 102b that run through the base 1 along the width direction, forming at least two cross grooves 102c.

[0028] Understandably, depending on the actual length of the base 1, the number of the first linear groove 102a and the second linear groove 102b can be increased, and a corresponding number of cross grooves 102c can be formed.

[0029] Furthermore, in order to divert and suction, the positioning adsorption pipeline 4 includes a suction pipeline 41 and several branch pipelines 42. One end of each branch pipeline 42 is connected to the suction pipeline 41, and the other end is connected to and communicates with the center of the cross groove 102c. The flow is diverted through the branch pipelines 42, so that the negative pressure suction of the two sides of the cross groove 102c is relatively uniform.

[0030] In one embodiment, please refer to Figure 2 In order to facilitate the on / off control of each zone, the on / off component 302 includes a solenoid valve, which is installed one by one at the end of the second diversion pipeline 33. The on / off of each zone is controlled by opening and closing the solenoid valve.

[0031] Understandably, when the solenoid valve of the corresponding zone is closed, the negative pressure suction of that zone is shut off; conversely, when the solenoid valve of the corresponding zone is open, the negative pressure suction of that zone is unblocked.

[0032] In one embodiment, please refer to Figure 2 The inner side of the partition frame 101 is fitted with a honeycomb panel 5, which provides a high-strength and lightweight support platform. The air drawn by the vacuum pump flows through these honeycomb units to ensure uniform distribution of adsorption force.

[0033] Understandably, after the honeycomb panel 5 is inserted into the partition frame 101, it can be fixed by adhesive bonding, such as epoxy resin bonding.

[0034] In one embodiment, please refer to Figure 2 The inner bottom wall of the partition frame 101 is provided with a flow guide grid groove 6, which serves as a vacuum collection pipe to optimize airflow distribution and connect multiple cellular partitions to the total vacuum.

[0035] This utility model also provides a composite material cutting machine, including a vacuum adsorption plate as described in any of the above, which serves as a workpiece support platform for the cutting machine. The workpiece is adsorbed and positioned on the vacuum adsorption plate by vacuum adsorption, so that the cutting machine can perform subsequent stable cutting. Specifically, flexible materials such as carbon fiber are laid on the vacuum adsorption plate, and adsorption positioning is formed by drawing a vacuum, so that the subsequent cutting head can move and cut.

[0036] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail as follows: Both the partitioned adsorption pipeline 3 and the positioning adsorption pipeline 4 are connected to a vacuum pump to provide negative pressure suction. At this time, the solenoid valve of the partitioned suction end 301 at the bottom of the partitioned frame 101 below the cutting position is opened to form suction force, adsorbing the workpiece onto the adsorption panel 2. In addition, there is also suction force at the position of the guide groove 102. When the cutting blade moves to another partition, the solenoid valve of the previous partition is closed, and the solenoid valve of the partition is opened, so that the partition conducts negative pressure suction according to the cutting position, concentrating the adsorption area at the cutting position and improving the adsorption stability of the cutting position. During the above switching process, the position of the guide groove 102 always provides adsorption force on the workpiece, which can avoid the displacement effect of suction fluctuation on the composite material during partition switching.

[0037] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
