[0001] The invention relates to the technical field of cable processing, and in particular to automatic loading and unloading equipment for laser removal of wire insulation layers. Background Art

[0002] The general method of removing the insulation layer on the surface of the enameled wire is burning, solution pickling, and mechanical grinding. It is not only inefficient but also has different disadvantages. Removing the insulation layer on the surface of the enameled wire by burning not only pollutes the environment, but is also inconvenient to operate and has many safety hazards. The liquid after solution pickling not only pollutes the environment, but also may corrode human skin. The most important thing is that the end after paint removal is uneven, which is difficult to achieve for products with extremely high precision requirements. In addition to the high noise of mechanical grinding, the grinding wheel can easily cause damage to the metal wire of the wire body. Therefore, lasers are now commonly used to remove the insulation layer of the wire.

[0052] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0053] See also Figure 1-Figure 15 ,An automatic loading and unloading device for laser removal of wire insulation layer, comprising a frame 101, on which a laser wire stripping machine 100 is installed;

[0054] The laser wire stripping machine 100 is used to perform laser removal of the insulation layer of the wire 108;

[0055] The laser wire stripping machine 100 is a common component in the prior art and will not be described in detail here;

[0056] It also includes a transmission module, which is transmission-connected to two first conveyor belts 104, and a set of pusher plates 1041 are installed on the two first conveyor belts 104;

[0057] The transmission module includes two transmission rollers rotatably connected to the frame 101 and a driving motor 103 fixed to the frame 101. The output shaft end of the driving motor 103 is fixedly connected to a transmission roller (not shown in the figure). The two transmission rollers are both transmission-connected to the first conveyor belt 104, or the transmission rollers are transmission-connected to the first conveyor belt 104 through belt transmission, chain transmission or other transmission forms. A pulley 102 adapted to the first conveyor belt 104 is fixedly installed on the transmission roller. In order to facilitate the installation of the pulley 102, a pulley bracket 1021 is also provided on the frame 101.

[0058] A discharge end is provided on the right side of the first conveyor belt 104, and a material coding end is provided on the left side of the first conveyor belt 104. The first conveyor belt 104 is tilted downward from the discharge end to the material coding end. A group of regularly distributed support pulleys 105 are rotatably connected on the frame 101 and corresponding to the position inside the first conveyor belt 104.

[0059] The push plate 1041 is an L-shaped structure, and is used to push out the material holding plate 106 stacked on the second trapezoidal block 210 at the loading end;

[0060] Since the height of the discharge end is higher than that of the stacking end, the push plate 1041 can touch the material holding plate 106 at the discharge end, while at the stacking end, the push plate 1041 does not touch the material holding plate 106 and moves from under the stacking plate at the stacking end.

[0061] When the code plate is at the discharge end, the code plate is arranged below the first conveyor belt 104;

[0062] When the material-coding plate is at the material-coding end, the material-coding plate is arranged above the first conveyor belt 104;

[0063] The driving slope 1062, the slow-down slope 1061 and the return slope 1063 do not contact the extrusion beads at the material-coding end;

[0064] At the material-coding end, the first trapezoidal block 205 fully retracts under the action of the oil return spring and loses its limiting effect on the material-containing plate 106;

[0065] Under the action of the first conveyor belt 104, the pushed out material holding plate 106 moves toward the direction of the material coding end of the first conveyor belt 104. When the pushing plate 1041 moves to the material coding plate on the material coding end, under the pushing action of the pushing plate 1041, the pushing plate 1041 pushes the material holding plate 106 into the material coding plate on the material coding end. When the material coding plate on the material coding end receives the material holding plate 106 pushed by the pushing plate 1041, the hydraulic cylinder 203 at the material coding end drives the material holding plate 106 on the material coding plate to lift upward. When the material holding plate 106 is lifted upward, the two second trapezoidal blocks 210 retract. When the lifting height of the material holding plate 106 exceeds the second trapezoidal blocks 210, under the action of the reset spring, the two second trapezoidal blocks 210 limit the material holding plate 106 fed into the material coding plate from the bottom of the material holding plate 106, and the material coding plate is reset to the initial height.

[0066] Two stacking carts 200 are arranged in mirror image, and the two stacking carts 200 are respectively arranged at two ends of the first conveyor belt 104, and the material receiving plates 106 are stacked on the stacking carts 200;

[0067] A trolley bracket 202 is installed at the bottom of the material handling trolley 200, and an AGV trolley 201 is clamped at the bottom of the trolley bracket 202. A clamping piece 206 clamped with the frame 101 is installed on the trolley bracket 202;

[0068] A material holding mold 107 is regularly installed on the material holding plate 106, a wire 108 is installed on the material holding mold 107, and a wire stripping hole 109 is opened on the material holding mold 107 to cooperate with the wire 108 and the laser wire stripping machine 100;

[0069] The laser wire stripping machine 100 acts on the wire 108 through the wire stripping hole 109 , thereby achieving laser wire stripping of the wire 108 ;

[0070] A trigger driving member is mounted on the material holding plate 106;

[0071] The trigger driving member includes a slow-down slope 1061 arranged at the rear of the material receiving plate 106, the slow-down slope 1061 is arranged upward, and return slopes 1063 are arranged at the rear of the material receiving plate 106 and at positions corresponding to both sides of the slow-down slope 1061. Two driving slopes 1062 are arranged at the front of the material receiving plate 106. The slow-down slope 1061 has a length L1, and the return slope 1063 has a length L2, which is twice the length L1. The driving slope 1062 is provided with a length L3, which is 1.5 times the length L2.

[0072] By setting the slow-down slope 1061, the material holding plate 106 above the coding plate can be smoothly lowered;

[0073] The length L2 is longer than the length L1 because before the slow-descent slope 1061 supports the material holding plate 106 at the discharge end, the first trapezoidal block 205 needs to retract all its short sides so that the second trapezoidal block 210 and the first trapezoidal block 205 can support the material holding plate 106 at the same time, so that the material holding plate 106 can slowly descend;

[0074] The stacking plate is installed on the stacking vehicle 200, and a hydraulic cylinder 203 is installed between the stacking plate and the stacking vehicle 200;

[0075] Two triggering members arranged in mirror image and mounted on the stacking vehicle 200, the triggering members are triggered by the movement of the triggering driving member;

[0076] A limiting member installed on the material stacking vehicle 200 and used to limit the position of the material holding plate 106, the limiting member is linked with the trigger member;

[0077] The triggering member includes a first hydraulic push rod 208 fixed on the material handling vehicle 200, a first piston rod is provided on the first hydraulic push rod 208, an extrusion bead 207 is embedded in the end of the first piston rod, the oil circuit end of the first hydraulic push rod 208 is connected with a hydraulic pipe, the other end of the hydraulic pipe is connected with the limiter, the axis of the first piston rod is perpendicular to the conveying direction of the first conveyor belt 104, the extrusion bead 207 cooperates with the return slope 1063 and the driving slope 1062, and an oil return spring is sleeved on the first piston rod;

[0078] The limiting member includes a second hydraulic push rod 209 fixed on the material handling vehicle 200, the oil circuit end of the second hydraulic push rod 209 is connected to the hydraulic pipe, the second hydraulic push rod 209 is provided with a second piston rod, the end of the second piston rod is installed with a first trapezoidal block 205 matched with the slow-down slope 1061, the first trapezoidal block 205 is provided with a first slope, the first slope faces upward, the angle between the axis of the second piston rod and the axis of the first piston rod is 90°, and the axis of the second piston rod is perpendicular to the axis of the transmission roller;

[0079] During operation, the first conveyor belt 104 moves to the right discharge end, pushing the material holding plate 106 above the second trapezoidal block 210 at the loading end to move, and the moving material holding plate 106 moves relative to the material holding plate 106 above which is still limited by the material stacking vehicle 200;

[0080] At this time, when the bottom material receiving plate 106 is moving, the driving inclined surface 1062 on the material receiving plate 106 is triggered and acts on the squeezing bead 207. After the squeezing bead 207 is pressed, it will push the squeezing bead 207 to retract. After the squeezing bead 207 retracts, it drives the first piston rod on the squeezing bead 207 to retract. After the first piston rod on the squeezing bead 207 retracts, the hydraulic oil in the hydraulic pipe acts on the second hydraulic push rod 209 to extend the second piston rod. After the second piston rod is extended, the first trapezoidal block 205 connected to the second piston rod is pushed out, and the upper short side of the first trapezoidal block 205 at the feeding end contacts the bottom side of the upper material receiving plate 106 and supports it.

[0081] Due to the first inclined surface on the first trapezoidal block 205, the material holding plate 106 can be gradually and steadily lowered at the feeding end and the shaking of the internal materials can be avoided;

[0082] The cross section of the first piston rod is S1, the cross section of the second piston rod is S2, the material holding plate 106 has lengths c, b and d, the telescopic length of the first piston rod is length d, and the first trapezoidal block 205 has lengths e and f:

[0083] S2 / S1=X

[0084] Length b / length e=length c / length f=X

[0085] Length d / (length e+length f)=X

[0086] Two stacking limiters are symmetrically arranged and installed on the stacking vehicle 200 , and are used for stacking limit of the material holding plates 106 .

[0087] The stacking limiter includes a second trapezoidal block 210 slidably connected to the stacking trolley 200 , a return spring is installed between the second trapezoidal block 210 and the stacking trolley 200 , and a second inclined surface is provided on the second trapezoidal block 210 , and the second inclined surface faces downward.

[0088] The working principle of the present invention is as follows: since the height of the discharge end is higher than that of the material coding end, the push plate 1041 can touch the material holding plate 106 at the discharge end, and at the material coding end, the push plate 1041 does not contact the material holding plate 106, and moves from under the material coding plate at the material coding end. When the material coding plate is at the discharge end, the material coding plate is arranged below the first conveyor belt 104, and when the material coding plate is at the material coding end, the material coding plate is arranged above the first conveyor belt 104. The driving inclined plane 1062, the slow-down inclined plane 1061 and the return inclined plane 1063 do not contact the extrusion beads at the material coding end. At the material coding end, the first trapezoidal block 205 fully retracts under the action of the oil return spring and loses contact with the material holding plate 106. The limiting effect of the material plate 106 is that when working, the first conveyor belt 104 moves to the right discharge end, pushing the material plate 106 above the second trapezoidal block 210 at the loading end to move, and the moving material plate 106 moves relative to the material plate 106 above which is still limited by the material stacking vehicle 200. At this time, when the lowest material plate 106 moves, the driving inclined surface 1062 on the material plate 106 is triggered and acts on the squeezing bead 207. After the squeezing bead 207 is compressed, it will push the squeezing bead 207 to retract. After the squeezing bead 207 retracts, it drives the first piston rod on the squeezing bead 207 to retract. After the first piston rod on the squeezing bead 207 retracts, the hydraulic oil of the hydraulic pipe acts on The second hydraulic push rod 209 extends the second piston rod. After the second piston rod is extended, the first trapezoidal block 205 connected to the second piston rod is pushed out. The upper short side of the first trapezoidal block 205 at the feeding end contacts and supports the bottom side of the upper material holding plate 106. Under the action of the first conveyor belt 104, the pushed material holding plate 106 moves toward the material coding end of the first conveyor belt 104. When the pushing plate 1041 moves to the material coding plate on the material coding end, under the pushing action of the pushing plate 1041, the pushing plate 1041 pushes the material holding plate 106 into the material coding plate on the material coding end. The material coding plate on the material coding end receives the material holding plate 106 pushed by the pushing plate 1041. 06, the hydraulic cylinder 203 at the material encoding end drives the material receiving plate 106 on the material encoding plate to lift upwards, and when the material receiving plate 106 is lifted upwards, the two second trapezoidal blocks 210 retract. When the lifting height of the material receiving plate 106 exceeds the second trapezoidal blocks 210, under the action of the reset spring, the two second trapezoidal blocks 210 limit the material receiving plate 106 fed into the material encoding plate from the bottom of the material receiving plate 106, and the material encoding plate is reset to the initial height. When the material receiving plate 106 passes through the laser wire stripping machine 100, the material receiving mold 107 is picked up by the laser wire stripping machine 100, and the wire 108 in the material receiving mold 107 on the material receiving plate 106 is laser stripped in turn.

[0089] like Figure 16-Figure 20As shown, another embodiment of the present invention further provides an automatic loading and unloading device for laser removal of wire insulation layer with a stepping transmission mechanism. Specifically, the stepping transmission mechanism includes a machine table 1, on which a processing position 2 is provided. One end of the processing position 2 is a loading position 21, and the other end is a unloading position 22. Between the loading position 21 and the unloading position 22, at least a laser vaporization position 23 for laser vaporization removal of the outer coating on the surface of the material wire and a detection position 24 for detecting the removal state of the outer coating on the surface of the material wire are provided. The loading position 21, the laser vaporization position 23, the detection position 24, and the unloading position 22 are equidistantly distributed.

[0090] The machine table 1 is provided with a first bracket 3, a second bracket 4, a third bracket 5 and a stepper motor 6 in the area below the processing position 2; a first belt pulley 7 is movably mounted on the upper end of the first bracket 3 through a rotating connecting piece, and the first belt pulley 7 is rotatably fitted in the upper material position 21; an inner gear ring is provided on the first belt pulley 7; a second belt pulley 8 is movably mounted on the upper end of the second bracket 4 through a rotating connecting piece, and the second belt pulley 8 is rotatably fitted in the lower material position 22; the upper end of the third bracket 5 is movably mounted on the upper end of the third bracket 5 through a rotating connecting piece The movable assembly is provided with an eccentric wheel 9, which is periodically eccentrically meshed in the inner gear ring on the first pulley 7; the eccentric wheel 9 has a central axis, and the output end of the stepper motor 6 is connected to the central axis of the eccentric wheel 9, and the step-by-step driving force is transmitted through the eccentrically meshing eccentric wheel 9 and the first pulley 7; the first pulley 7 and the second pulley 8 are simultaneously sleeved with a second conveyor belt 10, and the material wire is placed on the second conveyor belt 10, and is step-by-step cyclically transmitted between the upper material position 21 and the lower material position 22 through the second conveyor belt 10. The stepper motor 6 transmits the stepping driving force through the eccentric wheel 9 and the first pulley 7 in eccentric meshing, which has high reliability and durability; the design of the eccentric wheel 9 can realize reciprocating trajectory motion. This movement mode helps to reduce vibration and impact, making the transmission process smoother, improving the transmission effect of the material wire, and thus improving the processing effect of the laser on the material wire and the detection effect after laser processing; and the transmission accuracy of the eccentric wheel 9 meshing with the inner gear ring is very high, which can be used in occasions requiring high-precision laser processing material wire transmission.

[0091] A third pulley 11 is provided on the central axis of the eccentric wheel 9 and the output end of the stepper motor 6 (the third pulley 11 provided on the central axis of the eccentric wheel 9 is omitted in the accompanying drawings), and a synchronous belt 13 is sleeved on the third pulley 11 provided on the central axis of the eccentric wheel 9 and the output end of the stepper motor 6; the provision of the synchronous belt 13 can lengthen the driving length of the stepper motor 6 and the eccentric wheel 9, which is beneficial for the assembly and use of the stepper motor 6 at a suitable position on the machine platform 1.

[0092] The second conveyor belt 10 is arranged on one side of the processing position 2, and a chain 14 that cooperates with the synchronous belt 13 for synchronous transmission is arranged on the other side of the processing position 2. The material wire is placed on the second conveyor belt 10 and the chain 14 for transmission at the same time; baffles 12 are arranged on the upper ends of both sides of the processing position 2, and the baffles 12 are used to limit the deviation movement of the material wire toward the upper ends of the processing position 2 during the transmission process, so as to realize the centered transmission of the material.

[0093] In this embodiment, the stepping transmission mechanism uses a stepper motor 6 to provide driving force. The stepper motor 6 has a fixed number of steps per rotation, which can achieve high-precision position control; the stepper motor 6 can maintain a large static torque when it stops receiving pulse signals, thereby improving the reliability of the transmission drive; the stepper motor 6 can quickly adjust the speed by changing the pulse frequency, and can quickly start, brake and reverse. When it is detected in the detection process that the material wire is unqualified in removing the outer coating, the stepper motor 6 can quickly adjust the rotation direction, which is conducive to the rapid rework of unqualified products and improves the molding quality of the product. ; By setting an inner gear ring on the first pulley 7 and setting an eccentric wheel 9 that eccentrically meshes with the inner gear ring, the stepper motor 6 can transmit step-by-step driving force through the eccentric wheel 9 and the first pulley 7 that eccentrically meshes, and this method has high reliability and durability; the design of the eccentric wheel 9 can achieve reciprocating trajectory motion, which helps to reduce vibration and impact, making the transmission process more stable and improving the transmission effect for the material wire; and the transmission accuracy of the eccentric wheel 9 meshing with the inner gear ring is very high, which can be applied to occasions that require high-precision laser processing material wire transmission. Therefore, this embodiment effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
