DETAILED DESCRIPTION

[0040] 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.

[0041] For cable splitting and cutting devices, please refer to Figure 1-10 As shown, it includes: a frame 00, a wire clamping mechanism 100, a wire dividing mechanism 200 and a wire cutting mechanism 300, which can complete the division and cutting of the cable.

[0042] like Figure 1 As shown, the cable 400 moves along the direction of the arrow X, and the cable 400 passes through the cable clamping mechanism 100 and then passes through the cable cutting mechanism 300;

[0043] like Fig.10 As shown, one of the structural modes of the flat cable 400 is that the flat cable 400 is formed by connecting a first wire body 410 and a second wire body 420. Fig.10 The front end of the middle cable 400 has been installed with a terminal. In actual use, the front end of the cable 400 may not have a terminal installed. The utility model mainly divides the cable 400, cuts and separates the ends of the cable 400, and cuts the first wire body 410 and the second wire body 420 after separation, and cuts the first wire body 410 and the second wire body 420.

[0044] like Figure 1 and Figure 6 As shown, the frame 00 mainly serves as a carrier, and the wire clamping mechanism 100, the wire dividing mechanism 200 and the wire cutting mechanism 300 are installed on the frame 00. The frame 00 is also provided with a protective shell 01 to cover some components and play a dust-proof role.

[0045] The wire clamping mechanism 100 comprises two symmetrical clamping heads 110 and a first driving assembly 120 for driving the clamping heads 110 to move toward each other or away from each other.

[0046] like Figure 3 As shown, the two clamps 110 are symmetrically distributed on the left and right. Figure 3 The state in the middle is a state where the two clamps 110 are facing away from each other. When clamping, the two clamps 110 should move toward each other to clamp the cable 400;

[0047] like Figure 8 As shown, a plurality of tooth plates 111 are arranged at intervals on the chuck 110, and tooth grooves 112 are formed between adjacent tooth plates 111. When in use, when the two chucks 110 are approached toward each other, the tooth plates 111 of one chuck are inserted into the tooth grooves 112 of the other chuck to engage with each other; the two chucks 110 are relatively close to each other, so as to better clamp the cable 400.

[0048] Furthermore, the two chucks 110 are provided with notches on the sides facing each other, and the notches are provided with a first guide surface 113 and a second guide surface 114 distributed in an eight-shaped pattern, and a clamping surface 115 is formed between the first guide surface 113 and the second guide surface 114. When the two chucks 110 move toward each other, the first guide surface 113 and the second guide surface 114 can better guide the cable 400 to move to the clamping surface 115, such as Figure 8 As shown, the clamping surface 115 is a vertical plane. When the cable 400 is clamped, the first cable body 410 is on the top and the second cable body 420 is on the bottom, that is, it is clamped vertically, so that the first cable body 410 and the second cable body 420 can both contact the clamping surface 115.

[0049] Furthermore, when the two clamps 110 clamp the cable 400, they contact the surface of the cable 400 instead of tightening the cable 400. In the clamped state, the cable 400 can still be pulled by an external force to move the cable cutting mechanism 300.

[0050] Furthermore, the wire clamping mechanism 100 also has two rollers 130, which are respectively installed at the front sides of the two clamps 110 and move toward or away from the clamps 110;

[0051] like Figure 1As shown, one roller 130 is installed on a chuck 110 through a roller bracket 131, and the other roller 130 is installed on the other chuck 110 through the roller bracket 131. The roller 130 moves with the chuck 110. In the moving direction of the cable 400, the cable 400 first passes between the two rollers 130 and then passes between the two chucks 110. The roller 130 can provide a certain resistance. The roller 130 clamps the cable 400, which can help the cable 400 move in a straight line better.

[0052] like Figure 6 As shown, a first guide rail 02 is provided on the frame 00 corresponding to each chuck 110, two first guide rails 02 are distributed in a straight line, and the chuck 110 is installed on the first guide rail 02 through a slider;

[0053] Furthermore, the first driving component 120 is a cylinder, and one cylinder is provided corresponding to each chuck 110; the cylinder is installed on the frame 00, and the output shaft of the cylinder is connected to the chuck 110, and the cylinder drives the chuck 110 to move along the first guide rail 02. The first driving component 120 drives the two chucks 110 to move toward each other or away from each other on the first guide rail 02, thereby clamping or releasing the cable 400.

[0054] Optionally, the first driving assembly 120 may also adopt a screw structure, a motor and gear combination structure, a motor and transmission belt combination structure, etc.

[0055] like Figure 1 , Figure 7 and Fig. 9 As shown, the wire splitting mechanism 200 has a wire splitting blade 210 and a second driving assembly 220 for driving the wire splitting blade 210 to move. The wire splitting blade 210 passes through one of the clamps 110 to cut and split the cable 400 at the position where the cable is clamped.

[0056] Figure 1 In the figure, the wire splitting mechanism 200 is installed corresponding to the clamping head 110 located on the right side, and the wire splitting blade 210 is installed at a mounting block 211. The shape of the mounting block 211 is not limited, and it mainly plays a bearing and supporting role; the mounting block 211 is assembled on the first guide rail 02 through a slider;

[0057] The second driving assembly 220 may be a cylinder, which is mounted on the chuck 110 , and the output shaft of the cylinder is connected to the mounting block 211 .

[0058] When in use, when the clamp 110 moves, the wire splitting mechanism 200 follows and moves on the first guide rail 02. After the two clamps 110 clamp the cable 400, the second drive component 220 drives the mounting block 211 to move along the first guide rail 02, and the wire splitting blade 210 moves toward the cable 400, piercing the middle position of the first wire body 410 and the second wire body 420. As the cable 400 continues to move along the X direction, after the cable 400 is split to a set length B, the second drive component 220 drives the mounting block 211 to move and reset along the first guide rail 02, and the wire splitting blade 210 leaves the cable 400, thereby completing the separation of the first wire body 410 and the second wire body 420 of the cable 400.

[0059] Optionally, the cutting and separation length of the flat cable 400 is set as required.

[0060] The chuck 110 is provided with a through slot 116 for the wire splitting blade 210 to pass through. The wire splitting blade 210 extends through the through slot 116 to the space between the two chucks 110 to cut the cable 400.

[0061] Optionally, a through slot 116 may be provided on at least one of the chucks 110 , or may be provided on both chucks 110 , both of which can achieve the purpose of cutting and separation.

[0062] Optionally, the second driving assembly 220 may also adopt a screw structure, a motor and gear combination structure, a motor and transmission belt combination structure, etc.

[0063] like Figure 4 As shown, the line splitting mechanism 200 is installed on Figure 4 The chuck 110 on the left, that is, the above-mentioned line dividing mechanism 200 is installed corresponding to the chuck 110 on the right; here, define Figure 4 The chuck on the left side is the left chuck 110a, and the chuck on the right side is the right chuck 110b. The cylinder 120a drives the left chuck 110a, and the cylinder 120b drives the right chuck 110b. Obviously, from Figure 4 It can be seen that the cylinder 120a is fixedly mounted on the frame 00 to drive the left clamp 110a to move left and right along the first guide rail 02; and the cylinder 120b is mounted on the first guide rail 02 through a slider to drive the right clamp 110b to move left and right along the first guide rail 02; in addition, the cylinder 120b is connected to an adjusting screw 140, which is mounted on the frame 00, and the distance between the left clamp 110a and the right clamp 110b can be adjusted by adjusting the screw 140;

[0064] More specifically, the strokes of the cylinders 120a and 120b are straight. After the cylinders 120a and 120b drive the left chuck 110a and the right chuck 110b to move toward each other to the maximum stroke, the distance between the clamping surfaces 115 between the left chuck 110a and the right chuck 110b is C. In order to accommodate cables of different diameters, the distance between the right chuck 110b and the left chuck 110a can be adjusted by adjusting the screw 140 so that the distance between the clamping surfaces 115 becomes C'.

[0065] like Figure 4-5 As shown, the wire cutting mechanism 300 has two symmetrical wire cutting blades 310 and a third driving assembly 320 for driving the wire cutting blades 310 to move toward each other or away from each other;

[0066] A first blade 311 and a second blade 312 are formed on the wire cutting blade 310 , and a distance between the first blades 311 on the two wire cutting blades 310 is smaller than a distance between the second blades 312 on the two wire cutting blades 310 ;

[0067] The first blade 311 is located above the second blade 312 . The first blade 311 of the wire cutting blade 310 corresponds to the first wire body 410 , and the second blade 312 corresponds to the second wire body 420 .

[0068] like Figure 5 As shown, the cable 400 moves between the cutting blades 310, and the cutting blades 310 are driven by the third driving assembly 320 to move toward each other until the two first blades 311 contact the first wire body 410;

[0069] Next, the two cutting blades 310 continue to move a distance D1, so that the two first blades 311 cut and cut the first wire body 410. At this time, the second wire body 420 may just touch the second wire body 420 or may not touch the second wire body 420.

[0070] Then, the flat cable 400 is pulled to move a displacement distance A, where the displacement distance A is set by the user's needs. The displacement distance A is the difference in length between the first wire body 410 and the second wire body 420 after being cut.

[0071] Then, the two cutting blades 310 continue to move a distance D2 so that the two second blades 312 cut and separate the second wire body 420 .

[0072] Finally, the cutting blade 310 is reset and the flat cable 400 is cut.

[0073] Further, the wire cutting blade 310 is mounted on the blade support 330;

[0074] The third driving assembly 320 includes: a screw rod 321 and a motor 322;

[0075] The blade support 330 is mounted on the screw rod 321. When the motor 322 drives the screw rod 321 to rotate, the two wire cutting blades 310 are driven to move toward each other or away from each other.

[0076] like Figure 6 As shown, a second guide rail 03 is also provided at the frame 100, and the blade holder 330 is threadedly connected to the screw rod 321 and installed on the second guide rail 03 through a slider, and the second guide rail 03 is parallel to the first guide rail 02; the curved motion of the screw rod 321 is converted into a linear movement of the blade holder 330 through the cooperation of the second guide rail 03.

[0077] Optionally, the third driving assembly 320 may also adopt a cylinder structure, a motor and gear combination structure, a motor and transmission belt combination structure, etc.

[0078] Furthermore, a feeding track 04 is provided on the frame 00 corresponding to the lower side of the cutting mechanism 300 , and the cut cable 400 falls onto the feeding track 04 and moves to a designated position.

[0079] Furthermore, the cable dividing and cutting device further comprises: a cable pulling mechanism (not shown in the figure), the cable pulling mechanism having a mechanical clamp and a fourth driving assembly, the fourth driving assembly pulling the cable 400 to move linearly;

[0080] When in use, the cable 400 needs to be Figure 1 The cable moves in the X direction, then the front end of the cable 400 is clamped by the mechanical clamp of the cable pulling mechanism, and after clamping, the cable is pulled to move in the X direction by the fourth driving component. The cable moves a set distance each time, and the cutting, separation and trimming of the cable can be automatically completed.

[0081] Optionally, a sensor or other structure may be provided corresponding to the wire pulling mechanism to sense whether a flat wire 400 enters, and then activate the mechanical clamp to clamp the flat wire 400.

[0082] The specific use of the utility model is further described below:

[0085] S30, the first driving assembly drives the two clamps to move toward each other to clamp the cable, and the roller clamps the cable at the same time;

[0086] S40, the second driving assembly drives the wire splitting blade to pass through the clamp and pierce the cable;

[0087] S50, the fourth driving assembly drives the mechanical clamp to pull the cable to move a distance B, and the cable separation blade cuts the cable by a distance B to partially separate the cable;

[0088] S60, the second driving component drives the line dividing blade to reset;
