[0064] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0065] Example 1

[0066] See also Figure 1 、 Figure 2 and Figure 3 This embodiment provides a non-contact liquid cutting device, which is used to perform non-contact cutting on liquid polymer 10.

[0067] In this embodiment, the non-contact liquid cutting device includes a base 100, an electrode plate 200, a tool holder module 300, a cutting tool 400, and a high-voltage power supply 500. The electrode plate 200 is disposed on the base 100, and the upper surface of the electrode plate 200 is used to place the liquid polymer 10 to be cut. The tool holder module 300 is disposed on the base 100, and the cutting tool 400 is detachably mounted on the tool holder module 300. The cutting tool 400 has a blade portion 410 of a predetermined length, and the blade portion 410 faces the upper surface of the electrode plate 200.

[0068] See also Figure 3 The high-voltage power supply 500 is used to provide a high voltage. The positive electrode of the high-voltage power supply 500 is electrically connected to the cutting tool 400, and the negative electrode of the high-voltage power supply 500 is electrically connected to the electrode plate 200 and grounded. It is understood that the high-voltage power supply 500 is used to provide a high voltage to the cutting tool 400. The high voltage electricity passes through the tip of the blade portion 410 of the cutting tool 400, ionizing the air medium and forming a charged ion wind. The ion wind is then used to segment the liquid polymer 10, achieving non-contact cutting. The ion wind extends along the length of the blade portion 410.

[0069] Optionally, the length of the ion wind is greater than or equal to the width of the liquid polymer 10 along the cutting direction, so as to facilitate cutting the entire liquid polymer 10. Of course, in some embodiments, the length of the ion wind can be less than the width of the liquid polymer 10 along the cutting direction to cut out the desired shape.

[0070] In this embodiment, the base 100 includes an adjustable base 110 and an insulating spacer 120 disposed on the adjustable base 110. The adjustable base 110 is used to adjust the height of the insulating spacer 120 in the vertical direction Z, thereby adjusting the distance between the electrode plate 200 and the cutter 400. The electrode plate 200 is disposed on the side of the insulating spacer 120 facing away from the base. The insulating spacer 120 prevents the voltage generated by the electrode plate 200 from being transmitted to the adjustable base 110, thereby improving safety.

[0071] Optionally, the insulating partition 120 is a rubber plate, a silicone plate, a ceramic plate or a glass plate, etc. It should be understood that the above is only an example and is not intended to limit the scope of protection of this application.

[0072] Furthermore, the adjustable base 110 includes a lower base 111, an upper base 112, and a lifting and adjusting mechanism 113 disposed between the lower base 111 and the upper base 112. One end of the lifting and adjusting mechanism 113 is connected to the upper base 112, and the other end is connected to the lower base 111. The lifting and adjusting mechanism 113 is used to adjust the height between the upper base 112 and the lower base 111. The insulating partition 120 is disposed on the upper base 112, and the tool holder module 300 is disposed on the lower base 111.

[0073] In some embodiments, the lifting and adjusting mechanism 113 is a small scissor-type lifting mechanism, wherein the lifting and adjusting mechanism 113 includes a scissor frame and a drive assembly. The ends of the scissor frame are respectively connected to the upper base 112 and the lower base 111. The drive assembly includes an adjustment motor and a screw. The adjustment motor drives the screw to rotate, and the screw drives the ends of the two cross-hinged scissor rods on the scissor frame to move closer together through a nut. Of course, a screw handle can also be used instead of a motor drive.

[0074] In other embodiments, the lifting adjustment mechanism 113 may also be an electric push rod, a linear motor, or an electric cylinder.

[0075] In this embodiment, the base 100 also includes a first sliding guide assembly 130 and a second sliding guide assembly 140. The first sliding guide assembly 130 is arranged on the upper base 112 along the first horizontal direction X, the second sliding guide assembly 140 is arranged on the first sliding guide assembly 130 along the second horizontal direction Y, and the insulating partition 120 is arranged on the second sliding guide assembly 140.

[0076] The first horizontal direction X is perpendicular to the second horizontal direction Y, and the second sliding guide assembly 140 is movable relative to the first sliding guide assembly 130 along the first horizontal direction X. In other words, the first sliding guide assembly 130 provides guidance along the first horizontal direction X. The insulating spacer 120 is movable relative to the second sliding guide assembly 140 along the second horizontal direction Y. In other words, the second sliding guide assembly 140 provides guidance along the second horizontal direction Y.

[0077] Specifically, the first sliding guide assembly 130 includes a first guide rail and a first slider. The first guide rail is arranged along the first horizontal direction X, and the first guide rail can be slidably arranged relative to the upper base 112. The first slider is slidably arranged on the first guide rail, and the first slider is connected to the second sliding guide assembly 140. The above-mentioned second sliding guide assembly 140 includes a second guide rail and a second slider, wherein the second guide rail is arranged along the second horizontal direction Y and slidably cooperates with the upper base 112, and the second slider in the second sliding guide assembly 140 is connected to the bottom of the insulating partition 120. Therefore, the position of the electrode plate 200 on the insulating partition 120 on the horizontal plane M1 can be adjusted by cooperating with the first sliding guide assembly 130 and the second sliding guide assembly 140, thereby adjusting the cutting position of the tool 400 on the liquid polymer 10 on the electrode plate 200, and realizing cutting of the liquid polymer 10 at different positions (please refer to Figure 9a 、 Figure 9b and Figure 9c ).

[0078] Please also refer to Figure 2In this embodiment, the tool holder module 300 includes a mounting base 310, a rotating base 320, and a plurality of tool holders 330. The mounting base 310 is mounted on the lower base 111 of the base 100, and the rotating base 320 is rotatably mounted on the mounting base 310. The plurality of tool holders 330 are disposed on the outer circumference of the rotating base 320, and each tool holder 330 is used to mount at least one tool 400. Thus, the tool 400 can be switched by rotating the rotating base 320, thereby changing different tools 400 for cutting, making operation more convenient.

[0079] In some embodiments, the tool holder module 300 also includes a tool changing drive mechanism (not shown), which is arranged on the mounting seat 310 and is transmission-connected to the rotating seat 320 . The tool changing drive mechanism is used to drive the rotating seat 320 to rotate, so as to realize automatic switching of the tool 400 .

[0080] Furthermore, the tool change drive mechanism includes a tool change motor and a rotary table, wherein the tool change motor is connected to the input shaft of the rotary table, and the output shaft of the rotary table is connected to the rotary seat 320, thereby driving the output shaft of the rotary table to rotate a preset angle. Optionally, the rotary table uses an indexer.

[0081] In some embodiments, the knife holder 330 is hingedly connected to the outer circumference of the rotating base 320, and the knife holder 330 can swing up and down in the vertical plane M2 relative to the rotating base 320. Therefore, when the knife holder 330 is not needed to install a knife, the knife holder 330 can be folded for storage. When the knife holder 330 is needed, the knife holder 330 is folded.

[0082] Optionally, the plurality of tool seats 330 are distributed in an array around the rotation axis of the rotating seat 320 .

[0083] Furthermore, each tool holder 330 may be provided with at least one tool 400 , and a plurality of tools 400 are arranged at intervals on the tool holder module 300 .

[0084] See also Figure 10 For example, two parallel blades 400 are provided on a mounting portion. During cutting, both blades 400 on the blade holder 330 are energized simultaneously, so that the blade edge 410 of each blade 400 on the blade holder 330 can generate ionized wind to cut the liquid polymer 10. Of course, in some embodiments, three, four, or other numbers of blades 400 can be provided on each blade holder 330 depending on cutting requirements. It should be understood that the above is merely illustrative and does not limit the scope of protection of this application.

[0085] See also Figure 10Optionally, the shape of the blade portion 410 includes one of a straight line, a curved line, a broken line, and a cross. Different blade portions 410 can be selected to cut different shapes. The curved line can be an arc or an S-shape. It should be understood that the above is merely an example and does not limit the scope of protection of this application.

[0086] Please also refer to Figure 6 and Figure 7 In some embodiments, the voltage provided by the high-voltage power supply 500 ranges from 5kV to 11kV. It should be noted that the voltage supplied by the high-voltage power supply 500 to the cutting tool 400 is directly proportional to the cutting depth of the liquid polymer 10 by the cutting tool 400. Similarly, the voltage supplied by the high-voltage power supply 500 to the cutting tool 400 is also directly proportional to the cutting speed of the liquid polymer 10 by the cutting tool 400. Therefore, when cutting the liquid polymer 10, the voltage supplied by the high-voltage power supply 500 can be gradually increased until it reaches a preset value to ensure effective cutting. Of course, the voltage can also be directly increased to the preset value.

[0087] In other embodiments, the voltage range provided by the high voltage power supply 500 may be selected to be 6 kV to 11 kV.

[0088] Optionally, the voltage range provided by the high-voltage power supply 500 may also be selected to be 6.8 kV to 10 kV.

[0089] Alternatively, the electrode plate 200 may be made of a conductive metal material, such as a copper plate, a steel plate, an aluminum plate, or an iron plate. It should be understood that the above is merely an example and does not limit the scope of protection of this application. In this embodiment, the electrode plate 200 is a copper plate.

[0090] Optionally, the material of the tool 400 can be selected from various conductive materials according to needs.

[0091] In some embodiments, the non-contact liquid cutting device also includes a high-speed camera 800, which is arranged on one side of the base 100 through a first bracket 810, and the shooting end of the high-speed camera 800 is facing the upper surface of the electrode plate 200, so as to facilitate the operator to observe the state of the liquid polymer 10 during cutting in real time.

[0092] Furthermore, the non-contact liquid cutting device also includes a lighting assembly 900, which is arranged on one side of the base 100 through a second bracket 910. The irradiation end of the lighting assembly 900 faces the upper surface of the electrode plate 200 and is used to provide a light source for the high-speed camera 800.

[0093] See also Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 This embodiment also provides a cutting method, which uses the non-contact liquid cutting device provided above. The cutting method includes the following steps:

[0094] S100: placing the liquid polymer 10 to be cut on the upper surface of the electrode plate 200;

[0095] S200: Select a cutting tool 400 and install it on the tool holder module 300;

[0096] S300: starting the high-voltage power supply 500 and increasing the voltage output by the high-voltage power supply 500 to a preset value;

[0097] S400: Cutting is completed, and the high voltage power supply 500 is turned off.

[0098] The cutting principle of the non-contact liquid cutting device provided in this embodiment is as follows: by applying high voltage to the cutter 400, discharge at the tip of the blade 410 ionizes the air, thereby generating an ion wind below the blade 410. This ion wind then cuts and separates the liquid polymer 10. The shape of the blade 410 can be varied to cut the liquid polymer 10 into a desired shape.

[0099] The non-contact liquid cutting device provided in this embodiment has the following advantages:

[0100] (1) Since ion wind is used during cutting, and ions are very small, the ion wind blown out is finer and has higher precision.

[0101] (2) Since the cutter 400 does not need to be in direct contact with the liquid polymer 10 itself when cutting the liquid polymer 10, the service life of the cutter 400 is greatly improved, and the types of liquids that can be cut are expanded.

[0102] (3) Ion wind is used to cut polymers. During the entire cutting process, no pollutants or noise are generated, so the impact on the environment is small and no harmful substances are produced. It is economical and environmentally friendly.

[0103] Example 2

[0104] See also Figure 8 This embodiment provides a non-contact liquid cutting device. This embodiment is an improvement made on the technical basis of the above embodiment 1. Compared with the above embodiment 1, the difference is:

[0105] In this embodiment, the non-contact liquid cutting device further comprises a support plate 600 and a third sliding guide assembly 700. The support plate 600 is vertically arranged on the lower base 111, and the third sliding guide assembly 700 is arranged on the support plate (600) along the first horizontal direction X.

[0106] The third sliding guide assembly 700 includes a third guide rail and a third slider. The third guide rail is arranged along the first horizontal direction X, and both ends of the third guide rail are fixedly connected to the support plate 600. The third slider is slidably disposed on the third guide rail.

[0107] At least one tool holder module 300 is provided. This embodiment shows three tool holder modules 300, and three third sliders are correspondingly provided on the third guide rail. Specifically, in order to more clearly describe the technical solution of this embodiment, the tool holder module 300 is described below as follows:

[0108] The tool holder module 300 is disposed on a third slider corresponding to the third sliding guide assembly 700, wherein the third slider of the tool holder module 300 is hingedly engaged, thereby allowing the tool holder module 300 to flip relative to the third sliding guide assembly 700 within a vertical plane M2 passing through the second horizontal direction Y, and the tool holder module 300 to slide along the third guide rail along the first horizontal direction X. The first horizontal direction X is perpendicular to the second horizontal direction Y. It will be appreciated that when the tool holder module 300 is not in use, the entire tool holder module 300 can be flipped upward and folded, and the folded tool holder module 300 can be moved to one side along the first horizontal direction X for storage to prevent interference with the tool holder module 300 in use.

[0109] Furthermore, in this embodiment, please refer to Figure 2 The tool holder module 300 includes a mounting seat 310, a rotating seat 320 and a plurality of tool seats 330. The mounting seat 310 is hingedly arranged on the corresponding third slider on the third sliding guide assembly 700, so that the mounting seat 310 can be flipped relative to the third sliding guide assembly 700 in a vertical plane M2 passing through the second horizontal direction Y, and the mounting seat 310 can slide along the first horizontal direction X on the third sliding guide assembly 700. The rotating seat 320 is rotatably arranged on the mounting seat 310, and a plurality of tool seats 330 are arranged on the outer peripheral surface of the rotating seat 320. Each tool seat 330 is used to install at least one tool 400.
