Description

Technical Field

[0001] The utility model relates to the technical field of cable processing equipment, and more specifically to a cable trimming and weaving shielding net device. Background Art

[0002] In the prior art, cables with shielding function usually include a shielding layer surrounding the inner conductor, and the shielding layer is usually composed of a braided shielding net, and is a tubular braided net formed by conductive wires. In order to install an electrical connector or a conductive terminal at the end of the cable, it is necessary to remove the outer insulating skin surrounding the braided shielding net, and then push the end of the braided shielding net (which covers the inner insulating skin) backward by a predetermined length in a direction substantially perpendicular to the extending direction of the inner conductor, and at the same time widen (expand) it.

[0003] Due to the strict requirements of the shielding system on grounding, it is very easy to cause poor grounding and discontinuity of the shielding layer, destroying its integrity. In order to ensure effective grounding of the shielding layer, the braided shielding net needs to be folded 180° first. However, after the braided shielding net is folded 180°, the shielding wires are relatively messy, which can easily affect subsequent operations.

[0004] In order to overcome the above problems and improve processing and production efficiency, the applicant modified the existing technology and proposed the following technical solutions. Utility Model Content

DETAILED DESCRIPTION

[0061] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0062] For cable trimming and braiding, please refer to Figure 1-11 As shown, it includes: a main frame 00, a cutting mechanism 01, a weaving direction switching mechanism 02 and a thread clamping mechanism 700.

[0063] The wire clamping mechanism 700 is used to clamp the cable and move the cable back and forth in the direction of wire feeding and wire outlet, and clamp the cable to facilitate subsequent operations; the cutting mechanism 01 is used to cut the outer insulation layer, aluminum foil, braided shielding net, inner insulation layer, etc. of the cable, and the braiding direction turning mechanism 02 is used to comb the braided shielding net neatly and turn it 180° to facilitate the subsequent installation of connection terminals or connectors.

[0064] like Figure 1-2 As shown, the main frame 00 adopts a cabinet structure, so that the cutting and turning of cables can be carried out in a roughly closed state, reducing environmental impact.

[0065] Continue as Figure 2-3As shown, the main frame 00 has a large panel, the slide rail 03 is horizontally installed on the large panel, the cutting mechanism 01 and the weaving direction turning mechanism 02 are horizontally installed in parallel, and the clamping mechanism 700 is located in front of the cutting mechanism 01 and the weaving direction turning mechanism 02; Figure 3 As shown, the position of the wire does not move, and the cutting mechanism 01 and the weaving direction turning mechanism 02 are installed on the slide rail 03. The cutting mechanism 01 and the weaving direction turning mechanism 02 are moved along the slide rail 03 by the driving component to switch the workstation; the driving component can be a commonly used driving structure such as a motor and a cylinder.

[0066] like Figure 3-5 As shown, the wire clamping mechanism 700 includes: two symmetrically arranged clamping members 710, a first screw rod assembly 720 and a first moving assembly 730;

[0067] A V-shaped opening is formed at the positions where the clamping members 710 face each other, and the cable is clamped between the two clamping members 710;

[0068] The first screw rod assembly 720 includes: a mounting frame 721, a first slide rail 722 mounted on the mounting frame 721, a first screw rod 723 arranged parallel to the first slide rail 722, and a first motor 724 driving the first screw rod 723 to rotate, and the first slide rail 722 and the first screw rod 723 are parallel to the slide rail 03;

[0069] The clamping member 710 is installed on the first slide rail 722 through a slider and is connected to the first screw rod 723. When the first motor 724 drives the first screw rod 723 to rotate, the two clamping members 710 move closer or farther away from each other to clamp or release the cable. The first motor 724 can rotate forward and reverse. When the first motor 724 rotates forward, the first screw rod 723 rotates forward, so that the two clamping members 710 move closer to each other along the first slide rail 722 to clamp the cable; when the first motor 724 rotates reversely, the first screw rod 723 rotates reversely, so that the two clamping members 710 move away from each other along the first slide rail 722 to release the cable.

[0070] Furthermore, the first moving assembly 730 includes: a second slide rail 731, a second screw rod 732 arranged parallel to the second slide rail 731, and a second motor 733 driving the second screw rod 732 to rotate, the mounting frame 721 is assembled on the second slide rail 731 through a slider and connected to the second screw rod 732, and the second motor 733 drives the mounting frame 721 to move along the second slide rail 731 to feed the cable into the cutting mechanism 01 or pull it out of the cutting mechanism 01;

[0071] The second slide rail 731 and the second screw rod 732 are perpendicular to the slide rail 03 , and the second motor 733 is connected to the second screw rod 732 via a belt assembly, thereby driving the second screw rod 732 to rotate.

[0072] like Figure 6-10As shown, the cutting mechanism 01 includes: a knife disc 100, a plurality of auxiliary knives 410, a plurality of main knives 420, a first bracket 210, a second bracket 220, a rotating power assembly 310, a feeding power assembly 320, a central tube 200 and a frame 300.

[0073] like Figure 6 As shown, a structure of the frame 300 is in a frame shape, which acts as a carrier and has a top plate 301, a bottom plate 302, a front side plate 303 and a rear side plate 304, which support various components of the cutting mechanism 01 during installation;

[0074] Of course, the frame 300 can be designed to be other shapes as long as it can play a supporting role.

[0075] The central tube 200 is arranged horizontally, and the central tube 200 is arranged hollow;

[0076] The center of the cutter head 100 forms a wire inlet 101 , the front end of the central tube 200 is inserted into the cutter head 100 , the rear end is supported on the rear side plate 304 of the frame 300 , and the wire inlet 101 corresponds to the front end opening of the central tube 200 .

[0077] The knife disc 100 is made of high-hardness hardware material and is disc-shaped as a whole.

[0078] The cutter disc 100 includes: a main body 110, a mounting disc 120 and a toothed disc 130. The main body 110, the mounting disc 120 and the toothed disc 130 are in an assembled relationship or an integrally formed relationship. The mounting disc 120 is located on the front side of the main body 110, and the toothed disc 130 is located on the rear side of the main body 110. The mounting disc 120 is mainly used to install the auxiliary knife 410 and the main knife 420, and the toothed disc 130 is subsequently cooperated with the rotating power component 310 to drive the cutter disc 100 to rotate.

[0079] There are four auxiliary knives 410 installed on the mounting plate 120, and the four auxiliary knives 410 are arranged around the circumference of the central opening 101. Similarly, there are four main knives 420 installed on the mounting plate 120, and the four main knives 420 are arranged around the circumference of the central opening 101, and the auxiliary knives 410 are located on the outside and the main knives 420 are located on the inside. Figure 9-10 As shown, when viewed from the front, the auxiliary knife 410 blocks the main knife 420 .

[0080] It is worth noting that if Figure 8 As shown, a protective plate is also provided on the front of the cutter head 100. Figure 5-8 As shown, for ease of viewing, the protective plate on the front of the blade disc 100 is hidden.

[0081] Continue as Figure 8As shown, the first bracket 210 and the second bracket 220 are sleeved on the central tube 200, the auxiliary knife 410 is connected to the first bracket 210 through the connecting rod a430, and a connecting block a211 is provided at the connection, and the main knife 420 is connected to the second bracket 220 through the connecting rod b440, and a connecting block b221 is provided at the connection; the connecting block a211 and the connecting block b221 are both provided with a slide groove 240, and the connecting block a211 connected to the connecting rod a430 connected to the auxiliary knife 410 is fixed to the first bracket 210, and the connecting block b221 connected to the connecting rod b440 connected to the main knife 420 is fixed to the second bracket 220. When the feeding power assembly 320 pushes the first bracket 210 and the second bracket 220 to move along the central tube 200, the connecting rod moves along the slide groove 240.

[0082] Continue as Figure 8 As shown, a mounting groove 121 is provided on the surface of the mounting plate 120, and the connecting rod is connected to the auxiliary knife 410 and the main knife 420 through a connecting arm 450. The connecting arm 450 is installed in the mounting groove. Under the pushing action of the connecting rod, the connecting arm 450 moves along the mounting groove 121, so that the auxiliary knife 410 and the main knife 420 are close to or away from the center of the wire inlet 101.

[0083] The rotating power component 310 is mainly used to drive the cutter disc 100 to rotate. Here, a bearing can be arranged between the front end of the center tube 200 and the cutter disc 100, and the rear end of the center tube 200 is fixed to the rear side plate 304, so that when the cutter disc 100 rotates, the center tube 200 will not rotate with the cutter disc 100; or, the front end of the center tube 200 is fixed to the cutter disc 100, and a bearing is arranged between the rear end of the center tube 200 and the rear side plate 304, so that when the cutter disc 100 rotates, the center tube 200 follows the rotation. Preferably, the center tube 200 does not rotate with the cutter disc 100.

[0084] The central tube 200 of the present embodiment does not rotate with the cutter head 100 ; the first bracket 210 and the second bracket 220 are sleeved on the outside of the central tube 200 via a sleeve 230 .

[0085] Furthermore, the sleeve 230 is sleeved outside the central tube 200 and can move along the central tube 200 under external force; a bearing is arranged between the second bracket 220 and the sleeve 230, and there is no bearing between the first bracket 210 and the sleeve 230. The first bracket 210 is arranged in a floating manner, so that when the cutter disc 100 rotates, the first bracket 210 and the second bracket 220 are assisted by the connecting rod and the connecting block to rotate synchronously with the cutter disc 100.

[0086] Furthermore, the feeding power assembly 320 pushes the first bracket 210 and the second bracket 220 to move relatively along the central tube 200, and the first bracket 210 and the second bracket 220 move in the direction close to the cutter disc 100 and away from the cutter disc 100;

[0087] In the process of the feeding power assembly 320 pushing the first bracket 210 and the second bracket 220 to move along the central tube 200 close to the cutter head 100, the auxiliary cutter 410 and the main cutter 420 will approach the center of the wire inlet 101 for cutting;

[0088] When the feeding power assembly 320 pushes the first bracket 210 and the second bracket 220 to move along the central tube 200 away from the cutter head 100, the auxiliary cutter 410 and the main cutter 420 will move away from the center of the wire inlet 101 to retract the cutter.

[0089] Furthermore, if Figure 8 As shown, the cutter disc 100 is provided with a groove body 140 for a connecting rod to pass through, one end of the connecting rod is limited in the slide groove 240, and the other end passes through the groove body 140 and is connected to the connecting arm 450. At the same time, the connecting rod is limited in the groove body 140 by a pin; during the rotation of the connecting rod around the pin, the connecting arm 450 is pulled to move in the installation groove 121 through the lever principle, thereby driving the auxiliary knife 410 and the main knife 420 to move.

[0090] Furthermore, four auxiliary knives 410 are provided, and each auxiliary knife 410 is provided with a connecting arm 450, a connecting rod a430 and a connecting block a211; similarly, four main knives 420 are provided, and each main knife 420 is provided with a connecting arm 450, a connecting rod b440 and a connecting block b221.

[0091] In the above-mentioned process of cutting, the connecting rod does not move forward and backward. When the first bracket 210 and the second bracket 220 move forward (i.e., move closer to the cutter disc 100), the end of the connecting rod moves along the slide groove 240, and the end of the connecting rod tilts up, and the front end of the connecting rod moves down, pushing the connecting arm 450 to move inward along the mounting groove 121, and the auxiliary knife 410 and the main knife 420 cut;

[0092] During the process of retracting the knife, the connecting rod will not move forward or backward. When the first bracket 210 and the second bracket 220 move backward (i.e., move away from the knife disc 100), the end of the connecting rod moves along the slide groove 240. When the end of the connecting rod is pressed down, the front end of the connecting rod rises, pushing the connecting arm 450 to move outward along the installation groove 121, and the auxiliary knife 410 and the main knife 420 are retracted.

[0093] Furthermore, an elastic member 600 is connected between the first bracket 210 and the second bracket 220, and the first bracket 210 and the second bracket 220 are relatively maintained at the first position by the elastic member 600. During the cutting process, when the auxiliary knife 410 is not subjected to the reaction force of the cable, the first bracket 210 and the second bracket 220 are synchronously moved by the elastic member, that is, there is no relative movement between the two, and the auxiliary knife 410 and the main knife 420 are synchronously cut.

[0094] Specifically, Figure 8As shown, the elastic member 600 is a tension spring, and a plurality of elastic members 600 are arranged between the first bracket 210 and the second bracket 220, so that the force is more balanced, and the first bracket 210 and the second bracket 220 are kept in a tightly connected state (position) by the elastic member 600, i.e., the tension spring. During the cutting process, when the auxiliary knife 410 is subjected to the reaction force of the cable, it overcomes the elastic force of the elastic member 600, so that the first bracket 210 and the second bracket 220 produce relative movement, i.e., the first bracket 210 and the second bracket 220 move away from each other, and the auxiliary knife 410 and the main knife 420 do not feed synchronously.

[0095] like Fig.10 As shown, Fig.10 The state at this time is that the first bracket 210 and the second bracket 220 have produced relative movement, and the main knife 420 is closer to the cable inlet 101 than the auxiliary knife 410. At this time, if the cable has been inserted into the cable inlet 101, the main knife 420 can cut the cable during rotation.

[0096] The specific working principle of the cutting mechanism is further explained below:

[0097] In the initial state, the first bracket 210 and the second bracket 220 are defined as being away from the cutter disc 100, at which time the wire inlet 101 is opened to the maximum, and the auxiliary knife 410 is closer to the center of the wire inlet 101 than the main knife 420;

[0098] Next, the wire is inserted into the conducting port 101 manually or by a wire feeding mechanism;

[0099] The rotating power assembly 310 and the feeding power assembly 320 are started simultaneously;

[0100] The rotary power assembly 310 drives the cutter head 100 to rotate, and the auxiliary cutter 410, the main cutter 420, the first bracket 210, the second bracket 220, etc. also rotate synchronously. At this time, the wire may not be located at the exact center of the wire inlet 101;

[0101] In the process of synchronously feeding the auxiliary knife 410 and the main knife 420 driven by the rotation of the knife disc 100 and the feeding power assembly 320, the wire may first contact a certain auxiliary knife 410, and the auxiliary knife 410 continuously pushes the wire toward the center of the wire inlet 101;

[0102] Until the wire is located at the center of the wire inlet 101 and the plurality of auxiliary knives 410 are subjected to the reaction force of the wire, then, under the reaction force of the wire, the first bracket 210 no longer moves close to the cutter disc 100, the auxiliary knives 410 no longer advance, and the second bracket 220 continues to move close to the cutter disc 100, the main knife 420 continues to advance, and is closer to the center of the wire inlet 101 than the auxiliary knives 410;

[0103] By controlling the feed amount of the main knife 420, the outer insulation layer and the aluminum foil layer of the cable can be cut to expose the braided shielding mesh.

[0104] After the cutting is completed, the feed power assembly 320 pushes the first bracket 210 and the second bracket 220 to retract the knife. During the retraction process, the second bracket 220 moves away from the knife disc 100, and the main knife 420 retracts. Then the first bracket 210 and the second bracket 220 move synchronously away from the knife disc 100 again, and the main knife 420 and the auxiliary knife 410 retract synchronously again.

[0105] After cutting is completed, the wire can be pulled out of the wire inlet 101 .

[0106] During the wire pulling process, the beginning of the wire corresponding to the auxiliary knife 410 is pulled out, and the feed power assembly 320 drives the auxiliary knife 410 to press the beginning of the wire inward, so that the beginning of the braided shielding net opens, which is convenient for subsequent operations.

[0112] The belt 3224 drives the screw drive wheel 3221 to rotate, which further drives the screw 323 to rotate. During the rotation of the screw 323, the push plate 324 is pushed to move. The push plate 324 drives the sleeve 230 to move, and then pushes the first bracket 210 and the second bracket 220 to move.

[0116] The conduit 530 is detachably mounted on the mounting member 520. The first driving member 510 drives the conduit 530 to rotate. The conduit 530 is coaxially arranged with the central tube 200 and is hollow. Its diameter is smaller than that of the central tube 200 and can be inserted into the central tube 200.

[0117] A second driving member 540, wherein the first driving member 510 is mounted on the second driving member 540 through a slider and is driven to move by the second driving member 540, thereby driving the catheter 530 to move in a direction of inserting into or withdrawing from the central tube 200;

[0118] Furthermore, the catheter 530 can pass through the central tube 200 from the front end;

[0119] The first driving member 510 may be a motor, and the second driving member 540 includes: a motor 541 and a screw rod 542.

[0120] Optionally, the second driving member 540 may also be selected to have a cylinder and a slide rail. The first driving member 510 is installed on the slide rail through a slider. The cylinder pushes the first driving member to move along the slide rail, which can also push the catheter 530 to move.

[0121] After cutting the outer insulating layer and the aluminum foil, the cutting mechanism 01 also feeds the power assembly 320 to drive the auxiliary knife 410 to press the beginning of the wire inward, so that the beginning of the braided shielding net opens;

[0122] For the convenience of representation, the position where the outer insulation layer and aluminum foil are cut on the cable is defined as a;

[0123] The cable is inserted into the cable inlet 101 again, but the position a does not go over the auxiliary knife 410 and enter the cable inlet 101, and the cable is inserted into the cable inlet 101; at this time, the first driving member 510 and the second driving member 540 are running, pushing the guide tube 530 to approach the knife disc 100 during the self-rotation process and insert it between the braided shielding mesh and the inner insulating layer;

[0124] The purpose of the catheter 530 rotating during the movement is to prevent the braided shielding mesh from being pushed by the catheter 530 and stacking backwards, causing the catheter 530 to be unable to be inserted between the braided shielding mesh and the inner insulating layer.

[0125] The conduit 530 moves over the auxiliary knife 410, and the conduit 530 moves, and the left end of the conduit 530 moves to the left side of the auxiliary knife 410, that is, passes through the line inlet 101;

[0126] At this point, the conduit 530 is located between the braided shield and the inner insulation layer;

[0127] Next, the cutting mechanism 01 is activated, and the auxiliary knife 410 and the main knife 420 advance again. By the same principle, the advance amount of the main knife 420 is controlled to cut part of the woven shielding mesh;

[0128] After cutting the braided shield, pull the cable out.

[0129] Furthermore, the central tube 200 may also be connected to a suction device 800 to suck out and collect the cut waste from the central tube 200 .

[0131] In one embodiment, the weaving direction reversing mechanism 02 includes: two groups of brushes 610 distributed symmetrically and a third driving member 620 driving the brushes 610 to rotate;

[0132] When the third driving member 620 drives the brush 610 to move forward, the braided shielding net is broken up and combed. When the third driving member 620 drives the brush 610 to move backward, the braided shielding net is turned 180 degrees.

[0133] Furthermore, the weaving direction reversing mechanism 02 further includes: a fourth driving member 630, which drives the two groups of brushes 610 to move relatively away from or close to each other;

[0134] Specifically, Fig.11 As shown, two brushes 610 are symmetrically arranged, each brush 610 is mounted on a brush holder, and each brush 610 is driven by a third driving member 620, which may be a motor;

[0135] The two brushes 610 can be installed on the slide rail through a slider, and the fourth driving member 630 drives the two brushes 610 to move away from or closer to each other, and adjusts the position according to the diameter of the cable.

[0136] like Fig.11As shown, when the brush on the left rotates counterclockwise and the brush on the right rotates clockwise, it becomes a positive motion, which is to break up and comb the braided shielding net;

[0137] After combing is completed, turn the braided shield 180° while the left brush rotates clockwise and the right brush rotates counterclockwise.

[0138] Through the above, the cables can be trimmed and the braided shielding net can be scattered and turned over, which is more convenient for the subsequent installation of connection terminals or connectors.
