Description

Technical Field

[0001] The invention relates to the technical field of intelligent cutting tables, and in particular to an intelligent cutting table for cutting soft materials with a large expansion coefficient. Background Art

[0002] like Figure 1 As shown, the existing cutting bed film coating device is composed of two parts: a fixed rod 1 and a rotating film-retracting rod 2. During the film coating operation, one end of the film 700 is first fixed on the fixed rod 1, and the other end is wound on the rotating film-retracting rod 2, and then the rotating film-retracting rod 2 is allowed to rotate and tighten the film following the reciprocating motion of the cutting head 400, so that the film 700 is always covered on the surface of the soft material, achieving the function of auxiliary sealing and maintaining vacuum pressure. However, the existing cutting bed film coating method is generally suitable for cutting soft materials whose thickness does not change much after vacuum adsorption, but is not suitable for soft materials with a large expansion coefficient, because the soft materials with a large expansion coefficient will be separated from the film coating area and sent to the material picking table 200 after being cut off in the vacuum adsorption area and passing through the tooth plate 800, resulting in the material outside the film coating area (i.e., being transported to the material picking table 200) will start to deflate and expand prematurely, thereby affecting the vacuum airtightness of the vacuum adsorption area 300, and then affecting the cutting accuracy of the subsequent materials on the vacuum adsorption area 300. To solve this problem, the commonly used manual solution is to adopt manual assisted lamination, that is, to fill the leaking parts. This solution requires a lot of manpower cost, which is not conducive to reducing costs and increasing efficiency of enterprises. Summary of the invention

[0003] In view of the problems in the background technology, the purpose of the present invention is to provide an intelligent cutting table for cutting soft materials with a large expansion coefficient.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0005] An intelligent cutting table for cutting soft materials with a large expansion coefficient, comprising a cutting table body, a material picking table, a vacuum adsorption area, a cutting head, a first retractable film assembly, a second retractable film assembly and a film, wherein the first retractable film assembly is arranged across the upper front end of the material picking table and is fixedly connected to the cutting table body, the second retractable film assembly is arranged across the material picking table or above the vacuum adsorption area and is fixedly connected to the cutting head, one end of the membrane is connected to the first retractable film assembly, and the other end is connected to the second retractable film assembly, the cutting head is slidably arranged on the cutting table body, and can move back and forth along the length direction of the cutting table body, above the material picking table and the vacuum adsorption area, with the second retractable film assembly.

[0006] Furthermore, the intelligent cutting table also includes a tooth plate, which is fixedly mounted on the upper part of the cutting table body and is located between the material picking platform and the vacuum adsorption area, and is used to separate the material picking platform and the vacuum adsorption area.

[0007] Furthermore, the material picking platform is arranged at the front half of the upper part of the cutting table body, and the vacuum adsorption area is arranged at the rear half of the upper part of the cutting table body.

[0008] Furthermore, the first film retracting and releasing assembly includes a gantry frame spanning the upper front end of the picking table and fixedly connected to the cutting table body, a first rotating film retracting and releasing rod arranged on the inner side of the gantry for rotating the film retracting and releasing, and a rotating film retracting and releasing drive mechanism arranged at one end of the gantry and transmission-connected to the first rotating film retracting and releasing rod.

[0009] Furthermore, the rotary film retracting and unwinding driving mechanism includes a rotary motor, a motor wheel, a driven wheel and a transmission belt. The rotary motor is fixedly arranged at one end of the gantry. The motor wheel is arranged on the power transmission shaft of the rotary motor and is connected to the driven wheel through the transmission belt. The driven wheel is arranged at one end of the first rotary film retracting and unwinding rod.

[0010] Furthermore, the motor wheel has a one-way bearing, and the motor wheel is sleeved on the output shaft of the rotating motor through the one-way bearing.

[0011] Furthermore, the first film retracting and unretracting assembly also includes a rotating shaft, a counterweight rod and a tension rod arranged inside the gantry. The rotating shaft is rotatably arranged inside the gantry, and both ends of the rotating shaft are respectively connected to the counterweight rod and the tension rod through a first connecting plate.

[0012] Furthermore, a limit sensor is provided at one end of the gantry for sensing the tension rod.

[0013] Furthermore, the second film retracting and releasing assembly includes a second rotating film retracting and releasing rod straddling the material picking platform or the vacuum adsorption area and two second connecting plates arranged at both ends of the second rotating film retracting and releasing rod and used to connect the second rotating film retracting and releasing rod and the cutting head.

[0014] Compared with the prior art, the advantages of the present invention are as follows: it can ensure that the film is always attached to the material above the picking table and the vacuum adsorption area, and prevent the material that leaves the vacuum adsorption area from leaking and expanding prematurely, but keeps it in a certain negative pressure state, thereby ensuring the accurate cutting of subsequent materials in the vacuum adsorption area; compared with traditional cutting tables that require manual assisted lamination, the intelligent cutting table provided by the present invention has a wider range of applications, requires less manpower costs, and is beneficial for enterprises to reduce costs and increase efficiency.

[0015] In general, the coating device of the cutting table in the prior art is located above the vacuum adsorption area of ​​the cutting table, that is, the coating area is located on the vacuum adsorption area. Once the material in the vacuum adsorption area is cut and sent to the picking table through the tooth plate of the cutting table, this part of the material is separated from the coating area and is no longer affected by the adhesion of the film; while the coating device of the cutting table of the present application is partially located above the picking table and partially located on the vacuum adsorption area, that is, the coating area spans the picking table and the vacuum adsorption area. When the material on the vacuum adsorption area is cut and sent to the picking table through the tooth plate of the cutting table, a length of film will still be attached to it, so that it will continue to be in a certain negative pressure state, and will not leak and expand prematurely due to separation from the vacuum adsorption area.

When in use, the second rotating retractable film assembly 400 will move back and forth on the cutting bed body 100 together with the cutting head 400, ensuring that the film 700 is always attached to the material above the picking table 200 and the vacuum adsorption area 300, thereby ensuring that the material cut by the cutting head 400 can still maintain a certain negative pressure state after leaving the vacuum adsorption area 300, thereby ensuring the accurate cutting of subsequent materials on the vacuum adsorption area 300.

[0024] Please continue reading Figure 2 The intelligent cutting table provided in the embodiment of the present invention further includes a tooth plate 800, and the tooth plate 800 is fixedly arranged on the upper part of the cutting table body 100 and is located between the picking table 200 and the vacuum adsorption area 300, and is used to separate the picking table 200 and the vacuum adsorption area 300.

[0025] Please continue reading Figure 2 In the embodiment of the present invention, the picking table 200 is disposed at the front half of the upper portion of the cutting table body 100 , and the vacuum adsorption area 300 is disposed at the rear half of the upper portion of the cutting table body 100 .

[0026] Please continue reading Figures 2 to 4 In an embodiment of the present invention, the first film retracting and unwinding assembly 500 includes a gantry 501 spanning the upper front end of the picking table 200 and fixedly connected to the cutting table body 100, a first rotating film retracting and unwinding rod 502 arranged on the inner side of the gantry 501 for rotating the retracting and unwinding film 700, and a rotating film retracting and unwinding driving mechanism 503 arranged at one end of the gantry 501 and transmission-connected to the first rotating film retracting and unwinding rod 502.

[0027] Please continue reading Figure 4In an embodiment of the present invention, the rotating film retracting and unwinding driving mechanism 503 includes a rotating motor 503a, a motor wheel 503b, a driven wheel 503c and a transmission belt 503d, wherein the rotating motor 503a is fixedly arranged at one end of the gantry 501, the motor wheel 503b is arranged on the power transmission shaft of the rotating motor 503a, and is connected to the driven wheel 503c through the transmission belt 503d, and the driven wheel 503c is arranged at one end of the first rotating film retracting and unwinding rod 502.

[0028] Specifically, the motor wheel 503b and the driven wheel 503c can be synchronous wheels or sprocket wheels, and the transmission belt 503d can be a synchronous belt or a chain. When the motor wheel 503b and the driven wheel 503c are synchronous wheels, the transmission belt 503d is a synchronous belt; when the motor wheel 503b and the driven wheel 503c are sprocket wheels, the transmission belt 503d is a chain.

[0029] Specifically, the motor wheel 503b has a one-way bearing, and the motor wheel 503b is sleeved on the output shaft of the rotating motor 503a through the one-way bearing, so that the motor wheel 503b can only rotate clockwise following the rotating motor 503a, and cannot rotate counterclockwise.

[0030] Please continue reading Figure 3 and Figure 4 In an embodiment of the present invention, the first retractable film assembly 500 further includes a rotating shaft 504, a counterweight rod 505 and a tension rod 506 arranged on the inner side of the gantry 501, wherein the rotating shaft 504 is rotatably arranged on the inner side of the gantry 501, and both ends of the rotating shaft 504 are respectively connected to the counterweight rod 505 and the tension rod 506 through a first connecting plate 507.

[0031] Please continue reading Figure 4 In the embodiment of the present invention, a limit sensor 508 is provided on one side of the gantry 501, and the limit sensor 508 is used to sense the tension rod 506 to detect whether the film 700 is tensioned.

[0032] See also Figure 2 In an embodiment of the present invention, the second film retracting assembly 600 includes a second rotating film retracting rod 601 straddling the picking platform 200 or the vacuum adsorption area 300 and two second connecting plates 602 arranged at both ends of the second rotating film retracting rod 601 and used to connect the second rotating film retracting rod 601 and the cutting head 400.

[0033] The working principle of the intelligent cutting machine for cutting soft materials with large expansion coefficient provided in the embodiment of the present invention is as follows:

[0034] Before use, one end of the film 700 is first wound around the first rotating film retracting rod 502, and the other end is wound around the second rotating film retracting rod 601, and then the cutting head 400 is started to cut from front to back. At this time, the second rotating film retracting rod 601 will move from front to back along with the cutting head 400. During the process of the second rotating film retracting rod 601 moving from front to back along with the cutting head 400, the film 700 wound around the second rotating film retracting rod 601 will have a backward pulling force, thereby pulling the first rotating film retracting rod 502 to rotate counterclockwise to release the film, thereby making the film 700 attached to the surface of the soft material with a large expansion coefficient on the picking table 200 and the vacuum adsorption area 300. When part of the material on the vacuum adsorption area 300 is cut off, the material is fed to the picking table 200 to make it After passing the tooth plate 800, the vacuum adsorption area 300 is separated. At this time, some soft materials with a large expansion coefficient that have separated from the vacuum adsorption area 300 will deflate and expand due to the lack of adsorption power, affecting the accurate cutting of subsequent materials on the vacuum adsorption area 300. In order to ensure the accurate cutting of the materials on the vacuum adsorption area 300, the rotating motor 503a needs to control the first rotating film retracting rod 502 to release the film through the driven wheel 503c, so that the surface of the soft material with a large expansion coefficient sent to the picking table 200 can also be attached by the film 700, so that the soft material with a large expansion coefficient that has separated from the vacuum adsorption area 300 (that is, sent to the picking table 200) will not leak and expand, but will continue to be in a certain negative pressure state, thereby ensuring the accurate cutting of the materials on the vacuum adsorption area 300.

[0035] Among them, when the cutting head 400 moves forward, the film 700 will separate downward from the tension rod 506 due to its own weight. At this time, the tension rod 506 will tilt downward because there is no upward lifting force given by the film 700, and will separate from the sensing area of ​​the limit sensor 508. At this time, the rotating motor 503a needs to rotate clockwise. Due to the presence of the one-way bearing, the rotating motor 503a will drive the motor wheel 503b to rotate clockwise, and the motor wheel 503b will drive the driven wheel 503c to rotate clockwise through the transmission belt 503d. The driven wheel 503c will drive the second rotating film retracting rod 601 to rotate and retract the film until the tension rod 506 is sensed by the limit sensor 508 again. At this time, the film 700 and the tension rod 506 are in a close fit state, that is, the film 700 is in a tensioned state.

[0036] It should be noted that the intelligent cutting table for cutting soft materials with a large expansion coefficient provided in the embodiment of the present invention also involves some other components, such as: an intelligent controller, etc. These unmentioned components belong to the existing technology and no further explanation will be given because there has been no improvement.

[0037] Finally, it should be noted that the above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present invention.
