[0027] Embodiment: As Figure 1-7 shown, a flexible cable feeding mechanism includes a frame 100, a lifting unit 110, a separating unit 120 and a conveying and fixing module 200. The lifting unit 110 and the separating unit 120 are installed on the frame 100. The frame 100 includes a streamline 101 for carrying a tray, and the tray is used for storing flexible cables. The conveying and fixing module 200 includes a support frame 210, a conveying unit 220 and a fixing unit 230. The conveying unit 220 is connected to the support frame 210, and the fixing unit 230 is installed on the support frame 210. The lifting unit 110 is used to lift the tray so that the tray is separated from the streamline 101. The separating unit 120 is used to hold the tray lifted by the lifting unit 110. The support frame 210 is used to support the tray on the streamline 101. The fixing unit 230 is used to clamp the tray on the support frame 210. The conveying unit 220 is used to drive the support frame 210 to run so as to convey the tray on the support frame 210 to different workstations.

[0028] As shown Figure 1 in the figure, there are two parallel flow lines 101 provided on the rack 100. Separation units 120 are fixedly provided on both flow lines 101. The lifting unit 110 is located below the flow lines. The conveying and fixing module 200 is located between the two flow lines 101, and a plurality of work stations are provided along the length direction of the flow lines 101. During use, a stack of trays filled with flexible cables to be bent are placed on the flow line 101. The lifting unit 110 rises to push the trays upwards, so that the trays are separated from the flow line 101 until the lowermost tray is located above the separation unit 120. Then the lifting unit 110 descends, and only the lowermost tray is located below the separation unit 120. The separation unit 120 extends out and supports the stack of trays above, that is, the lowermost tray is separated. The lifting unit 110 continues to descend with the lowermost tray until the tray lands on the flow line 101. Then, after the support frame 210 and the fixing unit 230 clamp and fix the tray on the flow line 101, the conveying unit 220 drives the support frame 210 to operate to convey the tray to the next work station. When the flexible cables in the tray are taken out, the lifting unit 110, the separation unit 120 and the conveying and fixing module 200 use the same method to realize the stacking and conveying of empty trays. In this application, the separation unit 120 and the lifting unit 100 are used to realize the separation of full trays and the stacking of empty trays. The tray on the flow line 101 is clamped by the support frame 210 and the fixing unit 230, and the conveying between each work station of the tray is completed by the conveying unit 220. Therefore, this feeding mechanism can feed materials for the production of flexible cables. The whole process is fully automated controlled, and the purpose of accurately controlling the feeding amount can be achieved. Moreover, the trays can be automatically stacked after production, improving the production efficiency and reducing the production cost.

[0029] As shown Figure 5 in the figure, the lifting unit 110 includes a stepper screw motor 111, a lifting plate 112, a guide rod 113 and a support block 114. The stepper screw motor 111 is connected to the lifting plate 112, and the stepper screw motor 111 can drive the lifting plate 112 to operate. The first end of the guide rod 113 is fixedly connected to the lifting plate 112, and the second end of the guide rod 113 is fixedly connected to the support block 114.

[0030] The conveying and fixing module 200 is installed inside the flow line 101. There is a gap between the conveying and fixing module 200 and the flow line 101, and the support block 114 is located in the gap.

[0031] As shown Figure 4 and Figure 5As shown, the stepper screw motor 111 is located below the streamline 101. The stepper screw motor 111 can drive the support block 114 to move up and down, enabling the support block 114 to move from below the streamline 101 to above the streamline 101. Two support blocks 114 are fixedly arranged on the guide rod 113, and the two support blocks 114 are arranged in parallel. A nozzle 115 for adsorbing the tray is provided on the support block 114. The stepper screw motor 111 is vertically arranged on the frame 100, and the screw of the stepper screw motor 111 is connected to the lifting plate 112, thereby driving the lifting plate 112 to move up and down. A guide rod 113 is fixedly provided at each of the four corner ends of the lifting plate 112, and two guide rods 113 are fixedly connected to a support block 114, that is, a support block 114 is provided inside each of the two streamlines 101. During operation, the stepper screw motor 111 drives the support block 114 to move upward until the support block 114 lifts the tray on the streamline 101, and the nozzle 115 sucks the tray to prevent the tray from shaking. The stepper screw motor 111 continues to drive the support block 114 upward so that the lowermost tray is located above the separation unit 120. Then, the stepper screw motor 111 descends until the lowermost tray is lower than the separation unit 120. The separation unit 120 extends to catch the remaining trays except the lowermost one. The stepper screw motor 111 further descends to make the lowermost tray fall on the streamline 101. The support frame 210 and the fixing unit 230 clamp the tray on the streamline 101. The conveying unit 220 drives the support frame 210 to operate to convey the tray to the next station. Then, the support frame 210 and the fixing unit 230 return to the original station, clamp all the trays on the separation unit 120. The separation unit 120 retracts. The support frame 210 and the fixing unit 230 descend to make the tray fall on the streamline 101, waiting to separate the lowermost tray for the first time.

[0032] As Figure 1 and Figure 2 shown, the separation unit 120 includes a separation cylinder 121, a separation plate 122, and a guide rail 123. The separation cylinder 121 and the guide rail 123 are fixedly installed on the streamline 101. The separation plate 122 is slidably installed on the guide rail 123. The separation cylinder 121 is connected to the separation plate 122, and the separation cylinder 121 can drive the separation plate 122 to slide along the guide rail 123.

[0033] :On both sides of the streamline 101, a separation unit 120 is fixedly installed respectively, that is, there is a separation unit 120 on each of the two streamlines 101, which can hold the tray from both sides of the tray, improving the stability of the tray; the guide rail 123 is horizontally installed on the streamline 101, the separation plate 122 is located above the streamline 101, and the separation cylinder 121 can drive the separation plate 122 to move towards the inner side of the streamline 101, thereby holding the tray. The separation cylinder 121 can drive the separation plate 122 to move in the horizontal direction. When the separation cylinder 121 drives the separation plate 122 to move towards the inner side of the streamline 101, the separation plate 122 can hold the tray; when the separation plate 122 moves towards the outer side of the streamline 101, the tray can be separated from the separation plate 122 and fall on the flow channel 101.

[0034] As Figure 6 and Figure 7 shown, the conveying unit 220 includes a lead screw module, the support frame 210 is connected to the lead screw nut of the lead screw module, and the lead screw module drives the support frame 210 to move in the horizontal direction through the lead screw nut. The lead screw module includes a motor, a lead screw and a lead screw nut. The motor is connected to the lead screw and drives the lead screw to rotate. The lead screw nut is screwed on the lead screw. When the lead screw rotates, it drives the lead screw nut to perform a linear motion. The support frame 210 runs synchronously with the lead screw nut, thereby transporting the tray on the support frame 210 to different workstations.

[0035] As Figure 6 and Figure 7 shown, the fixing unit 230 includes a clamping cylinder 231 and a lifting cylinder 233. The clamping cylinder 231 and the lifting cylinder 233 are both fixedly installed on the support frame 210. The lifting cylinder 233 is used to eject the tray, and the clamping cylinder 231 is connected to the clamping plate 232, and the clamping cylinder 231 can drive the clamping plate 232 to clamp the tray. When the support frame 210 runs to the lower part of the tray, the piston rod of the lifting cylinder 233 extends to eject the tray, so that the tray is separated from the streamline 101, and the clamping cylinder 231 clamps the tray, thus playing a role in fixing the tray. Then, under the action of the conveying unit 220, after the tray is conveyed to the preset position, the clamping cylinder 231 releases the tray, and the lifting cylinder 233 descends to make the tray fall into the streamline 101.

[0036] As Figure 1 and Figure 3As shown in the figure, along the length direction of the streamline 101 on the rack 100, a loading position 102, a picking position 103, a buffer position 104, a discharging position 105 and an unloading position 106 are successively arranged. The lifting unit 110 and the separating unit 120 are arranged on the loading position 102, the buffer position 104 and the unloading position 106. The conveying and fixing module 200 is arranged on the picking position 103 and the discharging position 105. The conveying unit 220 on the picking position 103 can drive the support frame 210 to run between the loading position 102, the picking position 103 and the buffer position 104. The conveying unit 220 on the discharging position 105 can drive the support frame 210 to run between the buffer position 104, the discharging position 105 and the unloading position 106. The conveying and fixing module 200 on the picking position 103 is used to carry the tray loaded with the cable to be bent from the loading position 102 to the picking position 103, and then carry the empty tray on the picking position 103 to the buffer position 104. The conveying and fixing module 200 on the discharging position 105 is used to carry the empty tray from the buffer position 104 to the discharging position 105, and then carry the tray loaded with the bent cable on the discharging position 105 to the unloading position 106.

[0037] During operation, first, a stack of trays filled with cables is placed at the loading position 102. Under the action of the lifting unit 110 and the separating unit 120, the lowermost tray is separated from the stack of trays. Then, the fixing unit 230 in the conveying and fixing module 200 at the picking position 103 fixes the tray to the support frame 210. The conveying unit 220 transports the tray from the loading position 102 to the picking position 103. Then, the conveying unit 220 drives the support frame 210 to return to the initial position. The fixing unit 230 fixes the tray again. The external device takes away the cables in the tray and bends them. When the cables in the tray are taken out completely, an empty tray is formed. The empty tray runs to the buffer position 104 under the action of the conveying unit 220 and is stacked at the buffer position 104. The conveying unit 220 in the conveying and fixing module 200 at the discharging position 105 transports the empty tray at the buffer position 104 to the discharging position 105. The processed cables are transported by the external device to the tray at the discharging position 105 until the tray is full of cables. Then, the conveying unit 220 transports the full tray to the unloading position 106. After a certain number of trays are stacked at the unloading position 106, the full trays are removed manually or by an external device. Therefore, the present application can automatically meet the requirements for trays during the processes of loading, picking, discharging and unloading of cables, and can complete the operations of automatically separating trays and stacking trays, improving the work efficiency and reducing the processing cost.

[0038] As Figure 6 and Figure 7As shown, a support platform assembly is provided on the support frame 210. The support platform assembly includes a first support platform 211 and a second support platform 212. Fixing units 230 are provided below both the first support platform 211 and the second support platform 212. A baffle 107 is fixedly provided on the flow line 101, and a photoelectric sensor 108 is fixedly provided on the baffle 107. The baffle 107 is located at the loading position 102, the buffer position 104, and the unloading position 106. Photoelectric sensors 108 are fixedly installed on the first support platform 211 and the second support platform 212, and the photoelectric sensors 108 are used to confirm whether the product is in place. The lifting cylinder 233 is connected to the support platform assembly to drive the up and down movement of the support platform assembly. Initially, in the conveying and fixing module 200 at the material taking position 103, the first support platform 211 is at the loading position 102 and the second support platform 212 is at the material taking position 103. In the conveying and fixing module 200 at the discharging position 105, the first support platform 211 is at the discharging position 105 and the second support platform 212 is at the unloading position 106. When the first support platform 211 at the loading position 102 receives the tray, the conveying unit 220 operates to move the first support platform 211 at the loading position 102 to the material taking position 103, and place the tray on the flow line 101 at the material taking position 103. Then the conveying unit 220 drives the support frame 210 to return. The second support platform 212 moves upward under the action of the lifting cylinder 233 and holds the tray. The clamping cylinder 231 drives the clamping plate 232 to clamp the tray. The external module sucks the wire harness in the tray at the material taking position 103 and transports it to a preset position for bending processing. The conveying and fixing module 200 at the discharging position 105 can move the empty tray from the buffer position 104 to the discharging position 105 and the full tray at the discharging position 105 to the unloading position 106 in the same way.

[0039] The operation method of this application includes the following steps:

[0040] Step 1: Place a stack of trays containing unbent wire harnesses on the flow line 101 at the loading position 102;

[0041] Step 2: The stepping screw motor 111 drives the support block 114 to move upward. The support block 114 jacks up all the trays on the flow line 101, and the suction nozzle 115 sucks the tray to prevent the tray from shaking. The stepping screw motor 111 continues to drive the support block 114 to move upward so that the lowermost tray is located above the separation unit 120;

[0042] Step 3: Then the stepping screw motor 111 descends until only the lowermost tray is lower than the separation plate 122, and the separation cylinder 121 drives the separation plate 122 to extend out to catch the remaining trays except the lowermost one;

[0043] Step 4: The stepping screw motor 111 further descends to make the bottom tray fall on the flow line 101, thereby automatically completing the separation operation of the bottom tray;

[0044] Step 5: The lifting cylinder 233 drives the first support platform 211 upward and holds the tray, and the clamping cylinder 231 drives the clamping plate 232 to clamp the tray from both sides of the tray, that is, the fixing unit 230 fixes the tray;

[0045] Step 6: The conveying unit 220 drives the first support platform 211 to move to the material taking position 103, the clamping cylinder 231 drives the clamping plate 232 to release the material tray, the lifting cylinder 233 descends, and the material tray falls on the streamline 101 of the material taking position 103;

[0046] Step 7: The conveying unit 220 drives the first support platform 211 to return to the loading position 102, and the separation plate 122 retracts, so that a stack of trays falls back on the streamline 101 of the loading position 102, and the second support platform 212 and the fixing unit 230 work together to fix the trays on the material extraction position 103, so that the external module can extract the materials and send them to the bending equipment for bending processing;

[0047] Step 8: After all the empty trays in the trays at the material taking position 103 are taken out, the conveying unit 220 conveys the empty trays on the second support platform 212 to the buffer position 104 for stacking. When stacking, the conveying unit 220 first conveys the empty trays to the streamline 101 of the buffer position, and then conveys the trays to the separation plate 122 through the lifting unit 110 on the buffer position;

[0048] Step 9: At the same time, the first support platform 211 transports a new tray to the material picking position 103. The empty tray is transported to the streamline 101 of the material discharging position 105 under the action of the conveying fixed module 200 located at the material discharging position 105. The bent cable is placed on the tray at the material discharging position 105. When the tray at the material discharging position 105 is full of cable, it is transported to the material discharging position 106 for stacking under the action of the conveying fixed module 200. After a certain number of trays are stacked in the material discharging position 106, the photoelectric sensor 108 is started to remind manual or external equipment to move the full trays away.

[0049] It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these modifications and improvements are all within the scope of protection of the present application. Therefore, the scope of protection of the patent of the present application shall be subject to the attached claims.
