[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] The existing cable shielding net processing mechanism basically uses rigid transmission parts, which may easily cause excessive force to cause wear of parts in the equipment, resulting in uneven incision of the shielding net or even partial uncutting of the shielding net. In addition, when the cable is eccentric, a smooth incision cannot be obtained, thereby reducing the production quality of the cable and making it uncompetitive in the market.

[0027] In view of the above problems, the present utility model application provides a cable shielding net cutting and flipping mechanism 100, please refer to Figure 1-Figure 2 , Figure 1 This is a three-dimensional structural diagram of an embodiment of the cable shielding net cutting and flipping mechanism of the utility model. Figure 2 yes Figure 1 The three-dimensional structural diagram of the cable shielding net cutting and flipping mechanism from another angle is shown, and the cable shielding net cutting and flipping mechanism 100 includes but is not limited to a workbench 110, a driving assembly 120, a holding assembly 130, a positioning assembly 140, a cutting assembly 150 and a flipping assembly 160. It should be noted that the terms "including" and "having" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or components inherent to these processes, methods, products or devices.

[0028] Specifically, the holding assembly 130, the positioning assembly 140, the cutting assembly 150, the flipping assembly 160 and the driving assembly 120 are sequentially arranged on the workbench 110 along the length direction of the workbench 110. The holding assembly 130 is used to hold one end of the cable, and the positioning assembly 140 fixes the other end of the cable. After the holding assembly 130 sends the cable into the positioning assembly 140, the holding assembly 130 and the positioning assembly 140 jointly keep the cable in a horizontal state, and cooperate with the driving assembly 120 to drive the cutting assembly 150 and the flipping assembly 160 to reciprocate along the length direction of the workbench 110 to facilitate the subsequent shielding net cutting and flipping process steps. The cutting assembly 150 can cooperate with the positioning assembly 140 to cut the shielding net of the cable, and the flipping assembly 160 is used to flip the shielding net.

[0029] In some other embodiments, the driving component 120 can also be set at other positions of the workbench 110. Of course, those skilled in the art can also set the position of the driving component 120 according to actual conditions, as long as it can realize the function of controlling the motion trajectory of the cutting component 150 and the flipping component 160.

[0030] Please continue reading Figure 1-Figure 2 , Optionally, in this embodiment, the workbench 110 further includes a first flat plate 111, a second flat plate 112 and a third flat plate 113 sequentially arranged along the length direction of the workbench 110. It can be seen that the cutting assembly 150 is arranged between the first flat plate 111 and the second flat plate 112, and a flip assembly 160 and a driving assembly 120 are also arranged between the first flat plate 111 and the second flat plate 112. The positioning assembly 140 is arranged between the first plate body 111 and the third plate body 113, and the holding assembly 130 is arranged on the side of the third flat plate 111 away from the positioning assembly 140. It should be noted that the terms "first", "second", etc. in the embodiments of the present application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined by the terms "first", "second", etc. may explicitly or implicitly include at least one of the features. In the description of the utility model, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0031] Please combine Figure 1-Figure 2 See also Figure 3 , Figure 3 yes Figure 1 The three-dimensional structural schematic diagram of the cutting component of the cable shielding net cutting and flipping mechanism shown is shown. Optionally, in this embodiment, the cutting component 150 includes a cylinder 151, a transmission member 152, a shielding cutting conduit 153, a fixed plate 154 and an adaptive device 155, wherein one end of the transmission member 152 is fixedly connected to the cylinder 151, and the other end is rotatably connected to the shielding cutting conduit 153. The shielding cutting conduit 153 rotates at a high speed driven by the cylinder 151 to cut off the shielding net, and the cylinder 151 and the transmission member 152 are both fixed to the fixed plate 154.

[0032] Please continue reading Figure 3 Optionally, the cutting assembly 150 also includes a guide rod 156, one end of the guide rod 156 is fixedly connected to the first flat plate 111, and the other end is fixedly connected to the second flat plate 112. The fixed plate 154 is sleeved on the guide rod 156 and can reciprocate between the first flat plate 111 and the second flat plate 112 along the axial direction of the guide rod 156. The fixed plate 154 is suspended above the workbench 110 so that the adaptive device 155 is suspended in the air, and the adaptive device 155 is not restricted by the workbench 110 when working.

[0033] Please combine Figure 3 See also Figure 4-Figure 5 , Figure 4 yes Figure 3 The schematic diagram of the three-dimensional structure of the adaptive device and the fixing plate of the cutting component of the cable shielding net cutting and flipping mechanism shown in FIG. Figure 5 yes Figure 4 Schematic diagram of the exploded structure of the adaptive device and the fixed plate of the cutting assembly of the cable shielding net cutting flipping mechanism shown in the figure. Optionally, in this embodiment, the fixed plate 154 includes a first plate body 1541 and a second plate body 1542 arranged in parallel with each other, and the adaptive device 155 is arranged between the first plate body 1541 and the second plate body 1542. The side of the first plate body 1541 away from the adaptive device 155 is fixedly connected to the driving assembly 120. Specifically, in this embodiment, each adaptive device 155 includes a mounting sleeve 1551 and a spring 1552. The mounting sleeve 1551 is sleeved on Spring 1552, spring 1552 can be compressed and extended in the installation sleeve 1551, one end of the installation sleeve 1551 is fixed to the first plate 1541, and the other end is fixed to the second plate 1542. When the driving component 120 drives the cutting component 150 to cut off the shielding net of the cable, the shielding conduit 153 abuts against the positioning component 140. It should be pointed out that the shielding conduit 153 performs the cutting step specifically under the drive of the cylinder 151. The shielding conduit 153 rotates at a high speed to cut off the shielding net. Therefore, after the shielding conduit 153 abuts against the positioning component 140, it is necessary to continue to apply pressure. Facing the continuous pressure of the driving assembly 120, since the first plate 1541 is fixedly connected to the driving assembly 120 on the side away from the adaptive device 155, the first plate 1541 will gradually approach the second plate 1542 under the action of the spring 1552. When the elastic force reaches a certain level, the first plate 1541 and the second plate 1542 jointly drive the cylinder 151 and the transmission member 152 to move toward the positioning assembly 140, avoiding the strong squeezing of the cutting shielding conduit 153 and the positioning assembly 140, buffering the pressure applied by the rigid transmission member 152, reducing the wear of components in the cable shielding net cutting and flipping mechanism 100, and extending the service life of the cable shielding net cutting and flipping mechanism 100. It should be noted that if there is no adaptive device 155, during the continuous pressurization process of the drive component 120, since the relative position of the drive component 120 does not move, when the drive component 120 senses that no movement has occurred, the drive component 120 may alarm, thereby affecting the continuous operation of the cable shielding net cutting and flipping mechanism 100. The setting of the adaptive device 155 avoids this situation.

[0034] Please continue to read Figure 4-Figure 5 Optionally, in this embodiment, the number of the adaptive devices 155 is four and they are symmetrically arranged on both sides of the shielded conduit 153 so that the first plate 1541 and the second plate 1542 are evenly stressed.

[0035] In this embodiment, the adaptive device 155 can also solve the problem of cutting the shielding net when the cable is eccentric and uneven. Specifically, when the holding component 130 holds one end of the cable and extends the cable into the positioning component 140 and waits for the step of cutting the shielding net to be performed, if the cable deviates from the shielding conduit 153, since the adaptive device 155 is suspended in the air, it does not have a preset movement track. Instead, according to the actual situation of the cable, the elastic force of the four springs 1552 can extend the shielding conduit 153 into the inside of the shielding net and abut against the positioning component 140 in the same or different manner. This can ensure that the shielding net is completely cut off at one time, and also improve the success rate of cutting the shielding net, the flatness after cutting, and the overall processing accuracy of the cable.

[0036] In some other embodiments, the spring 1552 is other elastic elements, and the number of the adaptive devices 155 is at least two and they are fixed symmetrically or centrosymmetrically between the first plate 1541 and the second plate 1542. Of course, those skilled in the art can also set the number, shape and position of the adaptive devices 155 according to actual conditions, as long as the functions of buffering pressure and solving the problem of shielding net cutting when the cable is eccentric can be achieved.

[0037] In some other embodiments, the fixing plate 154 is slidably connected to the workbench 110 .

[0038] See also Figure 3 Optionally, in this embodiment, the cutting component 150 also includes an in-situ sensing device 157, which is arranged on a side of the first plate 1541 close to the workbench 110. The in-situ sensing device 157 can record the initial position of the first plate 1541. After completing the cutting and flipping steps of the shielding net, since the first plate 1541 needs to be reset, the first plate 1541 is driven by the driving component 120 and gradually moves away from the first flat plate 111. When the in-situ sensing device 157 senses the first plate 1541, the driving component 120 stops moving and waits for the next cutting and flipping steps of the shielding net.

[0039] As for other structural features of the holding assembly 130 , the positioning assembly 140 , the flipping assembly 160 and the driving assembly 120 , they are within the comprehension of those skilled in the art and will not be elaborated here.

[0040] The above is a description of the various structural components, connection relationships and functions of this embodiment. The specific working process of the cable shielding net cutting and flipping mechanism 100 will be described below in combination with this embodiment.

[0041] In the present embodiment, when the cable shielding net cutting and flipping mechanism 100 is required to perform the cable shielding net cutting and flipping steps, firstly, one end of the cable is fixed by the holding assembly 130, and then the holding assembly 130 is started to slide toward the direction of the third plate 113, and the other end of the cable is inserted into the positioning assembly 140 and fixed to the positioning assembly 140. The positioning assembly 140 repeatedly squeezes and rolls the shielding net so that the shielding net of the cable is slightly unfolded to allow the shielding conduit 153 to extend into the inner wall of the shielding net. After the shielding conduit 153 extends into the inner wall of the shielding net, it abuts against the positioning assembly 140, and it is necessary to continue to apply pressure so that the shielding conduit 153 can perform the cutting step. Facing the continuous pressure of the driving assembly 120, since the side of the first plate 1541 away from the adaptive device 155 is fixedly connected to the driving assembly 120, the first plate 1541 gradually approaches the second plate 1542 under the compression of the spring 1552. When the elastic force reaches a certain level, the first plate 1541 and the second plate 1542 jointly drive the cylinder 151 and the transmission member 152 to move toward the positioning assembly 140, so that the shielding conduit 153 is closely attached to the positioning assembly 140. The shielding conduit 153 is driven by the transmission member 152 and the cylinder 151 to rotate at a high speed to cut off the shielding net and move away from the cable. The spring 1552 between the first plate 1541 and the second plate 1542 is stretched, and the step of cutting off the shielding net is completed. Then, the shielding net is opened through the positioning component 140. The flipping component 160, driven by the driving component 120, completes the step of flipping the shielding net and exits the positioning component 140. Finally, the driving component 120 starts, driving the cutting component 150 and the flipping component 160 away from the positioning component 140. When the first plate 1541 is sensed by the in-situ sensing device 157, the driving component 120 stops moving, and the step of flipping the shielding net is completed, waiting for the next step of cutting and flipping the shielding net.

[0042] Furthermore, the present invention also provides a wire cutting machine 200, see Figure 6-Figure 7 , Figure 6 This is a three-dimensional structural diagram of an embodiment of the utility model wire cutting machine. Figure 7 yes Figure 6 The wire cutting machine shown is a three-dimensional structural schematic diagram with part of its cover removed. The wire cutting machine 200 includes but is not limited to the aforementioned cable shielding net cutting and flipping mechanism 100 , an electrical control unit 210 and a cover 220 .

[0043] Specifically, the cable shielding net cutting and flipping mechanism 100 is arranged above the electrical control unit 210, and a storage space for placing the electrical control unit 210 is provided below the wire cutting machine 200. The cable shielding net cutting and flipping mechanism 100 and the electrical control unit 210 are both covered by a machine cover 220, which can protect the cable shielding net cutting and flipping mechanism 100 and the electrical control unit 210 and extend the service life of the wire cutting machine 200.
