Description

Technical Field

[0001] The invention relates to the field of cutting devices, in particular to an automatic cable cutting device based on an ultrasonic method. Background Art

[0002] The principle of ultrasonic cutting is to use the effect of ultrasonic waves to make the blade produce instantaneous telescopic vibration, so that the blade and the workpiece collide repeatedly under high acceleration in a very short period of time. As a result, a tiny broken layer is generated on the surface of the workpiece while it is being processed.

[0003] The cable uses a protective sheath to wrap multiple battery cells together. When recycling the cable, removing the rubber protective sheath on the outside of the cable is an important preliminary processing step. When removing the rubber protective sheath, ultrasonic cutting causes minimal extrusion and damage to the conductor, insulation layer and other structures inside the cable, which can maintain the integrity of the cable's internal structure to the greatest extent, so that different parts can be recycled separately later.

[0004] When removing the protective cover on the outside of the cable, the existing ultrasonic cutting device usually pulls the cable on the cutting table so that the cable continues to pass through the cutter, thereby cutting the protective cover on the outside of the cable with the cutter. However, due to various reasons such as the layout and winding transportation of the used cable, the battery cells may rotate inside the protective cover, making it difficult for the cutter of the existing cutting device to cut the protective cover along the gap between the battery cells, which can easily cause the cutter to contact the battery cell and cause damage to the battery cell. The contact between the cutter and the battery cell can easily cause wear to the cutter, thereby reducing the service life of the cutter. Summary of the invention

Detailed implementation mode

[0032] The embodiments of the present invention will be described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as a limitation of the present invention. For those not specified in the embodiments regarding specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in this field or according to the product specifications.

[0033] Refer to Figure 1 and Figure 2 , an automatic cable cutting device based on the ultrasonic method, including a bottom plate 1, and a cutting mechanism 2 for moving and cutting the cable is arranged on the upper part of the bottom plate 1. The cutting mechanism 2 includes a conveying component 27 arranged on the bottom plate 1. The conveying component 27 includes moving frames 271 symmetrically arranged front and back on the upper part of the bottom plate 1. The upper part of the moving frame 271 is in a U-shaped structure. Clamping wheels 272 are rotatably arranged on one side close to the middle of the bottom plate 1 of the two longitudinal sections of the U-shaped structure of the moving frame 271. The clamping wheel 272 on the left is located on the left side of the left ear plate 22, and the clamping wheel 272 on the right is located on the right side of the right ear plate 21. A bi-directional screw 273 is rotatably arranged on the upper part of the bottom plate 1, and the bi-directional screw 273 is threadedly connected to the two moving frames 271 respectively.

[0034] Continue to refer to Figure 1 and Figure 2 , on the rear part of the rear moving frame 271, transmission rods 274 are symmetrically arranged left and right and rotatably. The transmission rods 274 are connected to the clamping wheels 272 at corresponding positions on the rear moving frame 271 through belts. The two transmission rods 274 are connected through a belt. A power motor 275 is fixedly installed on the lower left side of the rear moving frame 271, and the output shaft of the power motor 275 is fixedly connected to the left transmission rod 274.

[0035] When the cable needs to be cut, the operator first rotates the bidirectional screw 273 according to the outer diameter of the cable, so that the bidirectional screw 273 synchronously drives the two moving frames 271 to adjust in the opposite direction, so that the moving frame 271 drives the clamping wheel 272 thereon to move forward and backward, and then makes the distance between the clamping wheels 272 on the front and rear moving frames 271 able to clamp the cable, and then starts the power motor 275, the power motor 275 drives the transmission rod 274 on the left side to rotate, the transmission rod 274 on the left side drives the transmission rod 274 on the right side to rotate, and at the same time the transmission rod 274 drives the two clamping wheels 272 on the rear moving frame 271 to rotate in the same direction.

[0036] See also Figure 1 , Figure 3 and Figure 6 The cutting mechanism 2 also includes a right ear plate 21 fixedly installed on the right upper side of the base plate 1, a left ear plate 22 fixedly installed on the left upper side of the base plate 1, and circular hole grooves penetrating left and right are opened on the upper sides of the right ear plate 21 and the left ear plate 22. The circular hole grooves on the right ear plate 21 and the left ear plate 22 are arranged coaxially, and a fixed ring plate 23 coaxial with the circular hole groove on the right ear plate 21 is fixedly installed on the left side of the right ear plate 21, and a rotating cylinder 24 is rotatably arranged on the left side of the fixed ring plate 23, and an ultrasonic cutter 25 is radially slidably arranged in the middle of the rotating cylinder 24, and an adjusting screw 28 threadedly connected to the rotating cylinder 24 is rotatably arranged on the left side of the ultrasonic cutter 25.

[0037] The operator turns the adjusting screw 28 in advance according to the thickness of the cable protective cover, so that the adjusting screw 28 drives the ultrasonic cutter 25 to move radially along the rotating cylinder 24, thereby adjusting the position of the ultrasonic cutter 25, so that the ultrasonic cutter 25 close to the side of the axis of the rotating cylinder 24 can cut off the protective cover while the ultrasonic cutter 25 does not contact the battery cell. The cable is then inserted between the two clamping wheels 272 on the left side, so that the clamping wheel 272 on the left rear side pushes the cable to the right, so that the cable extends to the right into the circular hole groove of the left ear plate 22.

[0038] See also Figure 1 , Figure 3 , Figure 4 and Figure 6The cutting mechanism 2 also includes a direction adjustment component 26 jointly arranged on the left ear plate 22 and the rotating cylinder 24. The direction adjustment component 26 includes a rotating tube 261 rotatably arranged on the right side of the left ear plate 22. A follower disk 262 is fixedly installed on the right side of the rotating tube 261. Moving wheel frames 263 are arranged on the rotating tube 261 at equal intervals along its circumference. The moving wheel frame 263 is slidably connected to the rotating tube 261 along the radial direction. A supporting wheel 264 is rotatably arranged on one side of the moving wheel frame 263 close to the axis of the rotating tube 261. A fixed column 265 is fixedly installed on the right side of the moving wheel frame 263. A limiting portion 266 for limiting the fixed column 265 is provided on the rotating cylinder 24.

[0039] See also Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The limiting portion 266 includes a blocking plate 2661 which is slidably arranged on the left side of the rotating cylinder 24 in a direction parallel to the radial direction thereof, and a locking plate 2662 is slidably arranged on the left side of the rotating cylinder 24 in a direction parallel to the radial direction thereof. The blocking plate 2661 and the locking plate 2662 are symmetrically arranged, and the follower disk 262 is provided with straight waist-shaped grooves which correspond to the fixed columns 265 at equal intervals along its circumference, and the right end of the fixed column 265 is inserted into the right side of the follower disk 262 through the straight waist-shaped groove.

[0040] See also Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 A No. 1 screw rod 2663 is rotatably provided on the left side of the rotating cylinder 24. The No. 1 screw rod 2663 is threadedly connected to the blocking plate 2661. The locking plate 2662 is a hollow structure. The left side of the rotating cylinder 24 is fixedly installed on the No. 1 electric push rod 2664. The telescopic section of the No. 1 electric push rod 2664 is fixedly connected to the inside of the locking plate 2662.

[0041] The operator rotates the No. 1 screw 2663 in advance according to the distance between the gap between the battery cells of the cable and the axis of the rotating cylinder 24, so that the No. 1 screw 2663 drives the blocking plate 2661 to move toward the axis of the rotating cylinder 24. In the initial state, the telescopic section of the No. 1 electric push rod 2664 is in a retracted state, so that the No. 1 electric push rod 2664 drives the locking plate 2662 to be in a retracted position inside the rotating cylinder 24.

[0042] See also Figure 3 , Figure 4 , Figure 5 and Figure 6The limiting portion 266 also includes a rotating ring 268 rotatably arranged on the right outer side of the rotating tube 261, and inclined push blocks 2681 corresponding to the fixed columns 265 are fixedly installed on the outer side of the rotating ring 268 at equal intervals along its circumference. A No. 2 electric push rod 2682 is hinged on the left side of the movable disk 262, and the telescopic section of the No. 2 electric push rod 2682 is hinged to the rotating ring 268.

[0043] When the cable extends to the right into the circular hole groove of the left ear plate 22, the clamping wheel 272 continues to be rotated, so that the cable extends to the right into the rotating tube 261 and the follower disk 262 in turn. In the initial state, the telescopic section of the No. 2 electric push rod 2682 is in an extended state, so that the telescopic section of the No. 2 electric push rod 2682 drives the inclined push block 2681 to contact the fixed column 265 at the corresponding position by pushing the rotating ring 268, so that the inclined push block 2681 pushes the fixed column 265 to a position away from the axis of the rotating tube 261, and then the fixed column 265 drives the abutment wheel 264 through the moving wheel frame 263 to also be located at a position away from the axis of the rotating tube 261.

[0044] When the cable is extended into the interior of the follower disk 262, the telescopic section of the No. 2 electric push rod 2682 is contracted, so that the No. 2 electric push rod 2682 pulls the rotating ring 268 and the rotating tube 261 to rotate relative to each other, and the rotating tube 261 drives the inclined push block 2681 thereon to rotate synchronously, so that the inclined push block 2681 no longer pushes the fixed column 265.

[0045] See also Figure 3 and Figure 4 On the outer side of the rotating tube 261, L-shaped plates 267 corresponding to the moving wheel frame 263 are fixedly installed at equal intervals along its circumference, and a No. 2 screw rod 2671 is threadedly connected to the horizontal section of the L-shaped plate 267. A disc plate 2672 is rotatably provided at one end of the No. 2 screw rod 2671 close to the axis of the rotating tube 261, and a coil spring is provided between the disc plate 2672 and the moving wheel frame 263.

[0046] When the inclined push block 2681 no longer pushes the fixed column 265, the coil spring pushes the moving wheel frame 263 to move toward the direction close to the axis of the rotating tube 261 through its own elastic force, so that the moving wheel frame 263 drives the abutting wheel 264 to move to abut against the outer side of the cable, thereby causing the abutting wheel 264 to squeeze the protective cover of the cable, and then causing the abutting wheel 264 corresponding to the gap between the battery cells to push the protective cover toward the direction close to the axis of the rotating tube 261, and at the same time, the abutting wheel 264 drives the fixed column 265 thereon to move synchronously, and the abutting wheel 264 corresponding to the gap between the battery cells drives the fixed column 265 thereon to move a greater amount than the other fixed columns 265, so that the fixed column 265 corresponding to the gap between the battery cells is closer to the axis of the rotating tube 261 than the other fixed columns 265.

[0047] It should be noted that, for some cables with thicker protective covers, the operator can rotate the No. 2 screw 2671 so that the No. 2 screw 2671 drives the disc 2672 to move toward the direction close to the axis of the rotating tube 261, thereby increasing the pre-compression of the coil spring, so that the coil spring can push the protective cover of the cable through the abutment wheel 264 with greater force. Conversely, the pre-compression of the coil spring is reduced to prevent the abutment wheel 264 from squeezing and deforming the battery cell.

[0048] See also Figure 3 and Figure 5 A fixed block 269 is fixedly installed at equal intervals along the circumference of the left side of the movable disk member 262, and a tooth plate 2691 is slidably arranged on the fixed block 269 along the tangential direction of the movable disk member 262 through a guide column. The tooth plate 2691 corresponds to the fixed column 265 one by one, and a pushing spring is arranged between the tooth plate 2691 and the fixed block 269. A protruding column 2692 is fixedly installed on the left side of the tooth plate 2691.

[0049] In the initial state, when the inclined push block 2681 pushes the fixed column 265, the inclined push block 2681 also pushes the protruding column 2692, so that the protruding column 2692 drives the tooth plate 2691 to move to no longer contact with the fixed column 265, and at the same time compresses the push spring. When the inclined push block 2681 no longer contacts with the fixed column 265, the inclined push block 2681 no longer pushes the protruding column 2692, so that the push spring pushes the tooth plate 2691 to move against the fixed column 265 through its own elastic force.

[0050] When the movable wheel frame 263 drives the fixed column 265 to move toward the direction approaching the axis of the rotating tube 261, the fixed column 265 intermittently pushes the tooth plate 2691 in the direction away from itself. When the fixed column 265 stops moving, the pushing spring drives the tooth plate 2691 to move again to abut against the fixed column 265, so that the slot on the tooth plate 2691 extends to the outside of the fixed column 265, thereby blocking the fixed column 265 through the side of the slot of the tooth plate 2691 parallel to the tangent of the fixed column 265, thereby preventing the fixed column 265 from moving away from the axis of the rotating tube 261, avoiding the cable from pushing the abutment wheel 264 away from itself when moving to the right, so that the abutment wheel 264 always remains in the position at the gap between the battery cells.

[0051] See also Fig. 9 A lifting plate 29 is slidably provided on the left ear plate 22 in the vertical direction, a driving wheel 291 is rotatably provided on the right side of the lifting plate 29, an execution motor 292 is fixedly installed on the left side of the lifting plate 29, and the output shaft of the execution motor 292 is fixedly connected to the driving wheel 291, a hydraulic push rod 293 is fixedly installed on the upper part of the bottom plate 1, and the telescopic section of the hydraulic push rod 293 is fixedly connected to the lifting plate 29.

[0052] When the abutment wheel 264 is inserted to the position between the battery cells, the telescopic section of the hydraulic push rod 293 is extended to drive the lifting plate 29 to move upward, and the lifting plate 29 simultaneously drives the execution motor 292 and the driving wheel 291 to move upward, so that the cylindrical surface of the driving wheel 291 abuts against the outer surface of the rotating pipe 261, and then the execution motor 292 is started to drive the driving wheel 291 to rotate, and the driving wheel 291 drives the rotating pipe 261 to rotate synchronously through the friction force on the rotating pipe 261, so that the rotating pipe 261 drives the fixed column 265 to rotate synchronously through the moving wheel frame 263.

[0053] See also Figure 6 , Figure 7 and Figure 8 A C-shaped plate 2665 is fixedly installed on the right side of the locking plate 2662, and a locking member 2666 is provided on the right side of the rotating cylinder 24 for radial sliding. The side of the locking member 2666 close to the axis of the rotating cylinder 24 is a rod-shaped structure, and the side of the locking member 2666 away from the axis of the rotating cylinder 24 is a block-shaped structure. The block structure of the locking member 2666 is fixedly connected to the right side of the C-shaped plate 2665, and positioning holes for inserting the locking member 2666 are provided at equal intervals along the circumference of the fixed ring plate 23.

[0054] When the locking plate 2662 is in a state of being retracted inside the rotating cylinder 24, the locking plate 2662 drives the rod-shaped structure of the locking member 2666 through the C-shaped plate 2665 to be inserted into the positioning hole at the corresponding position of the fixed ring plate 23, so that the fixed ring plate 23 is fixedly connected to the rotating cylinder 24, thereby preventing the rotating cylinder 24 from rotating.

[0055] When the rotating tube 261 drives the fixed column 265 to rotate, the fixed column 265 rotates from the position of the locking plate 2662 to the position close to the blocking plate 2661, so that the fixed column 265 corresponding to the gap between the battery cells rotates to abut against the side of the blocking plate 2661, and the remaining fixed columns 265 all pass from the outer side of the blocking plate 2661 away from the axis of the rotating cylinder 24. At this time, the fixed column 265 drives the gap between the battery cells of the cable to the position corresponding to the ultrasonic tool 25 through the abutment wheel 264, and then extends the telescopic section of the No. 1 electric push rod 2664, so that the No. 1 electric push rod 2664 drives the locking plate 2662 to extend to the outside of the rotating cylinder 24.

[0056] Thereby, the locking plate 2662 moves to the other side of the fixed column 265 corresponding to the gap between the battery cells. At this time, the fixed column 265 corresponding to the gap between the battery cells is limited by the blocking plate 2661 and the locking plate 2662, and the rotating cylinder 24 and the rotating tube 261 are connected together, so that the rotating cylinder 24 drives the ultrasonic tool 25 to always correspond to the position of the gap between the battery cells.

[0057] As the locking plate 2662 moves, the locking member 2666 is driven to move synchronously through the C-shaped plate 2665, so that the rod-shaped structure of the locking member 2666 withdraws from the positioning hole of the fixed ring plate 23, so that the fixed ring plate 23 is no longer fixedly connected to the rotating cylinder 24, thereby allowing the rotating cylinder 24 to rotate, and then the clamping wheel 272 on the left drives the cable to move to the ultrasonic tool 25, so that the ultrasonic tool 25 cuts the gap between the battery cells of the cable, and then the clamping wheel 272 on the left drives the cable to move to the clamping wheel 272 on the right, so that the clamping wheel 272 on the right completes pushing the cable to the right side of the ultrasonic tool 25, and then the ultrasonic tool 25 completely cuts the protective cover of the cable.

[0058] When cutting the protective cover of the cable, the present invention also includes the following steps: In the first step, the operator first rotates the bidirectional screw 273 according to the outer diameter of the cable, so that the distance between the clamping wheels 272 on the front and rear movable frames 271 can clamp the cable, and the operator rotates the No. 1 screw 2663 according to the distance between the gap between the battery cells of the cable and the axis of the rotating cylinder 24, so that the No. 1 screw 2663 drives the blocking plate 2661 to move in the direction of the axis of the rotating cylinder 24, and the operator rotates the adjusting screw 28 according to the thickness of the cable protective cover, so that the adjusting screw 28 drives the ultrasonic cutter 25 to move radially along the rotating cylinder 24.

[0059] The second step is to start the power motor 275 to drive the clamping wheels 272 to rotate in the same direction, insert the cable between the two clamping wheels 272 on the left, so that the clamping wheel 272 on the left rear side pushes the cable to the right and extends into the interior of the follower disk 262, and retract the telescopic section of the second electric push rod 2682, so that the abutment wheel 264 pushes the protective cover toward the direction close to the axis of the rotating tube 261.

[0060] The third step is to extend the telescopic section of the hydraulic push rod 293 to drive the cylindrical surface of the driving wheel 291 to press against the outer surface of the rotating tube 261, start the execution motor 292 to drive the rotating tube 261 to rotate, so that the fixed column 265 rotates to press against the side of the blocking plate 2661, and extend the telescopic section of the No. 1 electric push rod 2664 to drive the locking plate 2662 to move to the other side of the fixed column 265 corresponding to the gap between the battery cells, so that the rotating cylinder 24 is connected to the rotating tube 261, and at the same time, the ultrasonic tool 25 always corresponds to the position of the gap between the battery cells.

[0061] In the fourth step, the clamping wheel 272 on the left drives the cable to move to the ultrasonic cutter 25, so that the ultrasonic cutter 25 cuts the gaps between the battery cells of the cable, and then the clamping wheel 272 on the left drives the cable to move to the clamping wheel 272 on the right, so that the clamping wheel 272 on the right pushes the cable to the right side of the ultrasonic cutter 25, and then the ultrasonic cutter 25 completely cuts the protective cover of the cable.

[0062] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
