[0035] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0036] like Figure 1 As shown, the present invention provides an online processing device for the inner core steel rope of an automotive zipper cable, comprising a feeding mechanism 1, a feeding mechanism 2, a cutting mechanism 3, a stripping mechanism 4, a stripping mechanism 5, an inspection mechanism 6, and a frame 8; the feeding mechanism 1, the feeding mechanism 2, the cutting mechanism 3, and the inspection mechanism 6 are sequentially arranged on the frame 8, and the stripping mechanism 4 and the stripping mechanism 5 are arranged between the cutting mechanism 3 and the inspection mechanism 6 via the frame 8;

[0037] like Figure 3-7 As shown, the feeding mechanism 1 includes two limiting roller groups 11, a pressing assembly 12, an anti-blocking mechanism 13, a guide roller group 14, and a side plate 15. The two limiting roller groups 11, the pressing assembly 12, the anti-blocking mechanism 13, and the guide roller group 14 are sequentially arranged on the side plate 15.

[0038] Two limiting roller groups 11 are respectively arranged longitudinally and transversely on one side of the pressing assembly 12;

[0039] The pressing assembly 12 includes one or more connecting rods 121, connecting shafts 122, fixed shafts 125, and connecting plates 127. The connecting shafts 122 are connected to the side plates 15. One end of the connecting rods 121 is connected to the connecting shafts 122, and the other end of the connecting rods 121 is provided with a pressure roller 123. The fixed shafts 125 are connected to the lower part of the pressure rollers 123 through the side plates 15, and the number of fixed shafts 125 is adapted to the number of pressure rollers 123. The connecting plate 127 is connected to the upper part of the connecting rods 121 through the side plates 15, and a buffer spring 128 is connected between the connecting plate 127 and the connecting rods 121.

[0040] The anti-blocking mechanism 13 includes a material-passing block 131, a sensing tube 132, a reset spring 135, and a sensor 138. The material-passing block 131 is provided with a through groove 135 in the horizontal direction. The sensing tube 132 passes through the through groove 135. Both ends of the sensing tube 132 are provided with a stop block 133. The size of the stop block 133 is larger than the size of the through groove 135. A reset spring 132 is provided between the stop block 133 and the side wall of the material-passing block 131. The sensor 138 is set at a position adapted to the sensing tube 132 through the side plate 15.

[0041] One or more steel ropes 7 pass simultaneously between two limiting roller groups 11. These two limiting roller groups 11 are arranged longitudinally and transversely to simultaneously limit the passing steel ropes 7 both laterally and longitudinally, preventing them from flying out. Because the steel ropes just unwound from the cable reel have a certain degree of bending, the steel ropes 7 are pressed between the fixed shaft 125 and the pressure roller 123 for transmission. The pressure roller 123 drives the connecting rod 121, which, under the action of the buffer spring 128, bounces slightly around the connecting shaft 122 as a fulcrum, buffering the unstable unwinding process and ensuring smooth feeding. The steel ropes 7 then pass through the sensor... The sensing tube 132 is guided out through the guide roller group 14. When a part of the steel rope 7 is clumped, the clumped area cannot pass smoothly through the sensing tube 132. The sensing tube 132 is affected by the traction force of the steel rope 7 and moves together towards the sensor 138. The sensor 138 can be an existing photoelectric sensor. When the stop block 133 is located at the sensor 138, it converts the light signal into an electrical signal and transmits it to the terminal. After receiving the signal, the terminal issues instructions to the relevant equipment, which facilitates the timely processing of the steel rope clumping area by the management personnel. The reset spring 132 plays a reset role for the sensing tube 132.

[0042] The side plate 15 is provided with a support rod 124, and the middle part of the connecting rod 121 is connected to the support rod 124. The support rod 124 provides support for the undulating connecting rod 121. The connecting rod 121 can be an elastic rod to avoid interference with the upper and lower buffering of the connecting rod 121.

[0043] The connecting rod 121 is connected to the support rod 124 by fastener 126. The distance between the fixed shaft 125 and the pressure roller 123 can be adjusted by the fastener 126 to meet the requirements of the steel rope transmission speed.

[0044] The number of buffer springs 128 is matched with the number of connecting rods 121, and each connecting rod 121 is connected to the connecting plate 127 through a corresponding buffer spring 128. When multiple steel ropes 7 are being transmitted, each corresponding connecting rod 121 can buffer according to the different conditions of the corresponding steel rope 7, and each connecting rod 121 acts precisely on a single corresponding steel rope.

[0045] The bottom of the connecting plate 127 is provided with a limiting rod 129, which can limit the extent to which the connecting rod 121 tilts up, and prevent the connecting rod 121 from tilting up too much and colliding with the connecting plate 127.

[0046] A positioning element 136 is provided between the material feeding block 131 and the guide roller group 14. The positioning element 136 has positioning holes 137, and the number of positioning holes 137 is adapted to the number of connecting rods 121. Each steel rope 7 passes through the corresponding positioning hole 137, which serves to position the ropes and prevent them from tangling before processing.

[0047] like Figure 8-11 As shown, the feeding mechanism 2 includes two clamping assemblies 21 and a transferring assembly 22;

[0048] The clamping assembly 21 includes a first cylinder 211, an upper clamping plate 212, and a lower clamping plate 213. The piston rod of the first cylinder 211 is connected to the upper clamping plate 212, and the upper clamping plate 212 is located above the lower clamping plate 213.

[0049] The first cylinder 211 controls the upper clamping plate 212 to descend, clamping the steel rope 7 between the upper clamping plate 212 and the lower clamping plate 213, thereby achieving clamping and positioning of the steel rope 7. A protective pad 214, which can be a rubber pad, is provided at the bottom of the upper clamping plate 212. Since the contact area between the steel rope 7 and the upper clamping plate 212 is subjected to significant pressure, the protective pad 214 can protect this area and prevent the steel rope 7 from being damaged.

[0050] The material transfer assembly 22 is located between the clamping assembly 21 for pre-clamping and the cutting mechanism 3. The material transfer assembly 22 includes a fixed plate 221, a second cylinder 222, a material transfer plate 224, and a telescopic guide pipe 225. The material transfer plate 224 is connected to the second cylinder 222 through the fixed plate 221. The clamping assembly 21 for material transfer is located on the material transfer plate 224. Both sides of the clamping assembly 21 for material transfer are provided with material passing plates 223. The material passing plate 223 has one or more material passing holes 2231. The number of telescopic guide pipes 225 is adapted to the number of material passing holes 2231. The telescopic guide pipes 225 are connected to the corresponding material passing holes 2231.

[0051] Since more than one steel rope is being transmitted simultaneously, each steel rope is conveyed along the corresponding material through hole 2231 to the telescopic guide pipe 225, thus preventing the steel ropes from getting tangled together when the clamping assembly 21 clamps and positions the material.

[0052] The material clamping assembly 21 for material transfer moves back and forth under the action of the second cylinder 222 along with the transfer plate 224. A limit switch 227 is provided between the material clamping assembly 21 for material transfer and the cutting mechanism 3. The limit switch 227 can monitor the stroke range of the second cylinder 222 in real time. When the transfer plate 224 touches the limit switch 227, the limit switch 227 will send a signal, and the control system will stop supplying air to the second cylinder 222, thereby improving the accuracy of material transfer by the transfer assembly 22 and preventing the steel rope 7 from being in the wrong position, which would cause deviations in the subsequent peeling and shaving positions.

[0053] A guide rail assembly 229 is provided between the fixed plate 221 and the transfer plate 224. The guide rail assembly 229 is an existing component and can be a combination of a straight rail and a slider, so that the transfer plate 224 always moves along the same straight line.

[0054] The cutting mechanism 3 includes a support plate 31, a pressure plate 32, a third cylinder 33, and two cutters 34. The pressure plate 32 is located between the cutters 34 and the material transfer assembly 22. The top of the support plate 31 is provided with a pressing groove 311. The pressure plate 32 is located above the support plate 31 and is connected to the third cylinder 33. The two cutters 34 are arranged opposite to each other and connected to a fourth cylinder 35.

[0055] The steel rope 7 is pressed into the pressing groove 311 by the pressure plate 32, which plays a positioning role. The pressing groove 311 is preferably "V" shaped. Compared with the conventional arc-shaped groove structure, the "V" shaped pressing groove 311 can meet the transmission and positioning of steel ropes 7 of different diameters.

[0056] Because the steel rope inside the zipper cable is covered with a leather layer, the two cutters 34 are set opposite each other and cut the steel rope 7 at the same time. Compared with single-blade cutting, the double-blade cutting structure can process both sides of the steel rope 7 at the same time, which can better adapt to the cutting needs of leather layers of different thicknesses. In addition, the two blades can wear each other, extending the service life of the cutters.

[0057] Both the third cylinder 33 and the fourth cylinder 35 are cylinder connecting rod mechanisms. Cylinder connecting rod mechanisms can transmit greater power within a limited operating space, converting the expansion pressure of the cylinder piston into the rotational torque of the crankshaft, balancing inertial forces, and improving the positioning and cutting accuracy of the steel rope.

[0058] The peeling mechanism 4 includes a sixth cylinder 41 and a peeling workpiece 42, with the sixth cylinder 41 connected to the peeling workpiece 42;

[0059] The pattern-making mechanism 5 includes a seventh cylinder 51 and a pattern-making workpiece 52, with the seventh cylinder 51 connected to the pattern-making workpiece 52.

[0060] like Figure 2As shown, the inspection mechanism 6 includes a fifth cylinder 61, a vision inspection instrument 62, a lighting plate 63, and a fixed-length drive component 64; the fifth cylinder 61 is connected to the fixed-length drive component 64, the fifth cylinder 61 is located between the vision inspection instrument 62 and the lighting plate 63, and the vision inspection instrument 62 is located above the fifth cylinder 61.

[0061] The length-fixing drive unit 64 can be an existing ball screw and motor assembly. After the steel rope 7 has been stripped and grouted, the length-fixing drive unit 64 moves the fifth cylinder 61 to the target clamping position. The fifth cylinder 61 can be an existing clamping cylinder. The fifth cylinder 61 clamps the end of the steel rope 7 and is then pulled by the length-fixing drive unit 64 to below the vision inspection instrument 62, thus fixing the length of the processed steel rope 7. The vision inspection instrument 62 is an existing inspection device that captures images of the grouted part at the end of the steel rope 7 below and performs image comparison on the terminal. The steel rope 7 is monitored in real time online to detect the quality of the stripping process. Simultaneously, the pressure plate 32, controlled by the third cylinder 33, clamps the steel rope 7 between the pressure plate 32 and the support plate 31 to prevent slippage during cutting, which would affect the flatness of the cut surface. Two cutters 34, controlled by corresponding fourth cylinders 35, cut the steel rope 7 between them. The pre-clamping assembly 21 can pre-position the steel rope 7 during cutting, preventing the unwound steel rope 7 from continuing to move forward slightly due to inertia, thus affecting the accuracy of the steel rope transmission. After cutting, to facilitate the processing of the ends of the steel rope 7, the material transfer clamping assembly 21 clamps the steel rope 7. The pre-clamping clamping assembly 21 releases the steel rope 7, and the material transfer clamping assembly 21, controlled by the second cylinder 222, conveys the steel rope 7 forward. The steel rope 7 moves along the telescopic guide pipe 225 between the peeling mechanism 4 and the stripping mechanism 5.

[0062] This utility model discloses an online processing device for the inner core steel rope of an automotive zipper cable. A feeding mechanism 1 simultaneously and smoothly feeds several steel ropes 7. A feeding mechanism 2 conveys the processing ends of the steel ropes to a stripping mechanism 4 and a crimping mechanism 5 for sequential stripping and crimping. A sixth cylinder 41 raises and lowers the stripped workpiece 42, and a seventh cylinder 51 raises and lowers the crimped workpiece 52, providing space for the clamping of the inspection mechanism 6. After stripping and crimping, the inspection mechanism 6 clamps the ends of the steel ropes 7 for length and crimping inspection. A cutting mechanism 3 cuts the steel ropes 7 at the target position, and the stripping and crimping operations on the unwound steel rope ends are repeated in a cyclical manner.

[0063] The frame 8 is equipped with a guide ramp 81, which is located below the detection mechanism 6. After the processed steel rope is cut, the fifth cylinder 61 releases its grip on the steel rope, and the steel rope falls along the slope of the guide ramp 81 to the target collection position, which facilitates the collection of the processed steel rope.

[0064] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described.
